Description: METHOD AND SYSTEM FOR PATIENT-ORIENTED OPTIMIZATION OF ORDER OF CARE TREATMENTS AND PATIENT IDENTIFICATION CARD FOR USE IN SUCH A METHOD OR SUCH A SYSTEM. The invention relates to a method for patient-oriented optimization of an order of care treatments offered by care provider, wherein the degree of utilization of all means at the disposal of the care provider, which together with many afore-mentioned orders of care treatments con¬ stitute, in their mutual dependence, the care process, is maximized. The invention further relates to a system for patient- oriented optimization of an order of care treatments offered by care provider, wherein the degree of utiliza¬ tion of all means at the disposal of the care provider, which together with many afore-mentioned orders of care treatments constitute, in their mutual dependence, the care process, is maximized. The invention relates furthermore to a patient iden¬ tification card for use in such a method and in such a system. Within the scope of this application, the term 'patient' covers all of the following terms: patient, client, user, consumer, resident and insured person in as far as applied within the social service sector. The term 'care provider' includes all providers of care such as general practitio¬ ners, pharmacists, specialists, nurses, paramedics, insti¬ tutions providing care and the like. Within the social service sector there is a significant waste of means on the one hand, while on the other there are no or insufficient means available for urgent matters. Both waste and shortages threaten the attainable level of quality of the processes of primary care. Years of expe- rience, analyses and many experiments have made it clear that the following causal factors especially lie at the basis of the present situation: - many care providers are involved in providing care to the patient, each care provider organising severally a part of the care process concerning the patient. - the patient is not made to become actively involved in planning his own care process. - the management hardly have any relevant basic infor¬ mation at their disposal concerning the primary processes. - quality of care as a concept has not been put into practice. - as a consequence of lack of coherence, every person involved generates (being more or less forced to do so) an enormous bureaucracy. Consequently, the number of staff that could be employed in primary processes is restriced by about 20%. This bears hard on the patient (waiting lists, damage to the care provided) and on society as a whole (social waste) . - motivation among people and organisations concerned (local governments, insurance companies, providers) to become more patient-oriented is low through lack of per¬ spective, since the sphere of influence is so delicately balanced that an action by one party is viewed with dis¬ trust by the other parties. An important problem in the social service sector is that the patient is not actively involved in the planning of his own order of care treatments. It is a trend within the social service sector, to make the patient more actively involved in this. The way in which this is done anticipates an expected future strengthening of the legal position of the patient as regards the medical treatments he is receiving. In liability regulations these medical actions are usually seen as agreements of exertion between patient and care providers. In view of the increase in (often painful and energy-consuming) legal procedures as a consequence of actions which are alleged to have been performed incor¬ rectly or medical treatments which have not been carried out to the satisfaction of the patient, there is an ever stronger call in society for a treatment agreement between patient and care provider. In the Netherlands, this desire finds its expression in a proposal for a new Act concer¬ ning the medical treatment agreement. Apart from this, a patient will be treated several times for different disorders by different providers of care. In their files, these care providers have files containing data about the illness of the patient, treatments etc. This results in the existence of many medical files per patient, scattered over several files of care providers. In The Netherlands alone, there are on average 14 medical files per inhabitant, that means about 200 million files in all. This situation entails a great deal of (already difficult) communication, many unnecessary actions, much unnecessary bureacracy, but above all it means that the quality of overall care and the contribution of each in¬ dividual action is very difficult to measure. When a patient wants to have access to his own historical medical data, he wil usually need permission to inspect these files from different providers of care, if these can still be traced. But also in the case in which a care provider wishes to know something about a certain detail of a medical nature having to do with an illness of his patient in the past, this can be difficult to trace or only to be obtained from many other care providers. Hereby, a great deal of time is lost, which can have serious effects for the patient. An often recurring problem in health services is the delays for the patient. After an examination at the clinic or .the pronouncement of a diagnosis by a doctor, an in¬ definite- period of time may go by before the patient receives information as to the time and place at which a subsequent examination or an operation will take place. If a patient has to undergo several interdependent medical treatments, the dependent care activities are only planned after the care activities on which they depend have been performed. This type of planning mechanism causes an accumulation of waiting periods for the patient. As a consequence thereof, the patient will be in a state of uncertainty during a certain period, his private and business life becoming subordinated to the planning proce- dure of the care provider concerned. These 'costs' have never been defined as health care costs but they run into billions of guilders every year. What is meant here are costs which are shifted onto individuals or onto a group of people collectively, such as for instance the Sickness Benefit System or the Disablement Insurance Act/ General Disablement Act. It would therefore be beneficial to the patient to make this period last as short as possible. Apart from this, it would be advantageous to him if the period between the first and the last care treatment is fixed as early as possible. The care provider too, benefits from fixing periods of different treatments of a patient at as early a date as possible, since it will then be possible to make an early assessment of the equipment which will be required for these care treatments. Such requirements are, for in¬ stance, certain care providers for a care treatment, the location at which a care treatment will take place, the aids and drugs needed for the care treatment. When such data are known for all future patients, the available means can be used to their fullest extent. In a first aspect, the invention is characterized by a method and a system which optimizes the stream of patients of a care provider consisting of a multitude of an order of care treatments to be carried out per patient, by rendering these treatments interdependent by means of the permission given by the patient to carry out these care treatments, wherein said optimization consists of a mini¬ mization of length of time between first and last care treatment of an order of care treatments and a maximazat- ion of the degree of utilization of the means at the disposal of the care provider, consisting of care workers, aids, equipment, space and stocks of goods and drugs. In a second aspect, the invention is characterized by a method and a system which collects and manages data con- cerning the state of health of the patient, wherein all these date are the property of the patient and relate to care treatments, irrespective of the fact, that these have been carried out or are being carried out by different care providers, and the patient possesses an information carrier with a unique combination of personal data which provides him sole access to the date concerning his state of health which are present in the system. In the third aspect, the invention is characterized by a method and a system which contains the means offered by the care provider and the care treatments offered by the care providers and which can express these in units of time, costs or price per units of time, weight or volume, wherein the system determines the costs, price and dura- tion of a future order of care treatments, after the patient has given permission for them to be carried out. In a fourth aspect, the invention is characterized by a patient identification card, owned by every resident of a country in which the care provider concerned is situated, said card functioning as a key, by means of which permis¬ sion is granted for care treatment or order of care treat- ments on the owner and which provides the owner with sole access to an integral survey of his personal medical data. The card also functions as key to the system which con¬ tains a combination of personal data which is unique for that person, so that it is of no use and/or value to people other than himself. In a fifth aspect, the invention is characterized by a computer programme which has, using hardware equipment suitable for this purpose, sole access to the data con¬ tained on the patient identification card. The sixth aspect of the invention is characterized in that the system is continuously generating developing criteria which render the quality of care measurable and asses¬ sable, so that it will be possible, in some cases, to immediately compensate injured parties without having to look at the question of guilt, by which not only the patient is spared additional suffering, but by which the providers of care too, are given the opportunity to con¬ tinuously adjust and improve their care programmes. The seventh aspect is characterized by the built-in pos¬ sibility of obtaining a payment guarantee beforehand by coupling permissions to packages of care for which the patient is insured. The eighth aspect is characterized by the possibility of using the patient identification card as drug card, donor card or for the benefit of (alterable) expressions of a person's will in case of coma, incompetence, the matter of euthanasia, etc. It is the object of the invention the raise the quality of care and to drive back waste within and increasing the ■ availability of the care providers for the primary proces¬ ses of the social service sector, and to make use to measure of the means required, by which the drawbacks and problems mentioned previously are removed to a large extent. Waste is often confused with inefficiency. This is not correct. Especially in the social service sector, it happens that people are working very efficiently on use¬ less tasks. Efficienty requires well-defined goals. Since these do not exist, (health)care efficiency is an empty phrase. The invention ensures that goals will have to be set per treatment of each individual case, so that the ef- ficiency can be assessed as far as these goals are con¬ cerned. It will then be possible for similar cases in a different setting, to have a different efficieny. By deriving the secondary and tertiary processes from the primary processes, the efficiency of the former two can be determined. More in particular, the invention concerns an automatized planning system, which determines the order of care ac¬ tivities to be provided by care providers for the benefit of the treatment of a patient in such a way, that the duration of the order of care activities is as short as possible and the quality of the care offered is as high as possible and that the means required for this are used as efficiently as possible, wherein this automatized planning system uses a unique means of identification which belongs to the patient, by means of which the patient authorizes the user of the automatized planning system to carry out care activities for the benefit of the patient. Because it is the care treatments, which are the same the world over in their systematics, which are taken as a starting point, the planning system can be used in any care system. For this purpose, the invention provides a method of patient-oriented optimization of an order of care treat- ments offered by a care provider, comprising: - the reading of an access code by a computer programme loaded into a computer, said access code being incor- porated into a module of indelible data on a patient identification card, - the generating of an output signal following the posit¬ ive identification of the access code by the computer programme, - the reading of modules of variable data on the patient identification card by the computer programme by means of the output signal, - the processing of central data files filed in the main memory of the computer by the computer programme, said files concerning the care activities and/or the patient, and processing the data read on the patient identification card in such a manner, that an order of care treatments is generated which is optimally patient-oriented, and - the up-dating of the variable data on the patient iden¬ tification card and up-dating the central data files after the care treatment. For this purpose, the present invention moreover provides a system for patient-oriented optimization of care treat¬ ments offered by a care provider, comprising a patient identification card having a module with indelible patient data and an access code and further modules with variable data, and a computer programme loaded into a computer to which the patient identification card has sole access by means of the access code, the computer programme having access, after the access code has been read by means of reading equipment, to the further modules and to central data files, said computer programme being suitable to optimize the care treatments.' The system for data management consists of a computer programme describing a care provider as a process flow chart and a collection of information-carrying patient identification cards, wherein the computer programme has sole access to the data stored on the patient identifi¬ cation card and the patient identification card has sole access to the date stored in the files of the system concerning the state of health of the owner of this card. The computer programme is stored in a main memory to which personal computers are coupled by means of known tech¬ niques such as networks, said personal computers being located anywhere in the care institution where care treat¬ ments are performed. All personal computer are coupled in situ to equipment which is capable of reading information from and filing it on the patient identification card. According to known techniques, this information can be in an optical, magnetic or electronic form, or a combination of these forms. As a consequence of this, the way in which a patient passes through an order of care treatments can be op¬ timized, because the way in which the patient passes through the primary process, is taken as a starting point. Because the secondary and tertiary processes are geared thereto (by means of formulas of logistic management) , the efficiency of the two latter processes is heightened even more. This starting point therefore concerns a patient- (client-oriented) orientation. For the social service sector this is a unique starting point, because providers of care work in a production- and product-oriented manner. In that case, availability determines the order of care treatments. If there is any efficiency at present, this is organised in an unstructured manner within the secondary or tertiary processes. In that way, too, the manner in which the secondary and tertiary processes are coupled following the primary processes, is unique. By means of the invention it is possible, moreover, that the patient gives and records his permission for medical treatments to be carried out by the care provider prior to these treatments. In this way, the agreement of exertion takes on the character of a result-oriented agreement, because the care provider will for instance be forced, on the basis of the Act mentioned before, to explain to the patient what the treatment entails, what the risks are, what the consequences or possible results may be and whether there are any alternatives available. By having this recorded systematically by both care provider and patient in one single document, it will be possible to measure if and to what extent the expectations have been realised and what the consequences thereof should be. Apart from that, it will be possible for the patient to manage his entire file himself. Quality and efficiency can therefore be significantly increased if a central medical file is created, which is owned by the patient and to which the patient has complete access and to which the care provider to whom the patient has turned, has access for the relevant parts only. Since the files are the property of the patient, the latter can himself give permission to third parties to use data from his file. One could think, for instance, of scientific institutes who might be able to use these specific data for research. If a central system according to the invention is present in a care institution which contains all previously men¬ tioned means of the care institution and their mutual dependence, then it will be possible to create, while optimizing the degree of utilization, a planning per individual means. Such a system ensures that all means for a certain care treatment are present at the desired time and place, after a working schedule has been drawn up per individual means prior to the time at which the care treatment takes place. The result of this is that every care provider connected to such a care institution will know what his planning for the day, week or month will be, thus making it possible to minimize unproductiveness during his periods of presence at the institution. With regard to aids, drugs and other goods that may be required, this might lead to planning of the flow of goods and to stock management. The system, which couples the means required for carrying out all individual care treatments to these treatments and which knows the cost price per means per unit of time, will moreover be able to immediately determine the costs of a future order of care treatments during a certain period. Of its own accord, the system generates as it were stan- dards for a responsible type of care for similar patients with similar problems and at the same time it indicates what should be understood by 'care on the basis of the state of the art of medical science' on a day to day basis. This continuous developping of criteria makes it possible to couple a patient injury insurance to the system. This is not an insurance in the established sense of the word, but a provision which ensures that a care provider is compensated without all sorts of procedures and without going into the question of guilt, if the care provided was of a poor quality: for after all, providing care is first of all the work of man. The system will then be able to immediately trace the source of the problem so that effec- tive measures can be taken immediately. Should the in¬ cident repeat itself, then culpable behaviour can be deemed to have been established, in which case the proce¬ dures which are now usual will have to be followed. It will be possible, however, to deal with these in a short period of time, because all the facts are known directly and have been indisputably recorded. The invention also provides a patient identification card provided with a carrier containing modules with indelible patient date and access code and further modules with a memory capacity for variable data, which is eminently suitable for use in the method and the system according to the invention. If the patient possesses an information-carrying card which serves as a means of identification for the system and which provides sole access to his medical files stored in this system, it is essential that this card also con¬ tains some data of a personal nature which do not vary and which can be extremely relevant to certain care treat¬ ments. Examples of this are blood group, tissue typifica- tion, certain allergic reactions and for the future one might think of fingerprints or DNA-code. These characteristics will only need to be determined once, while nowadays it still happens more than once. The card could also contain data of ' a personal data which could have far-reaching consequences for the treatment but which could change during a person's life. One might think here of a donor card, persons who are the patient's con- fidants and who should be consulted in case of coma, expressions of a person's will (euthanasia) , etc. Because drugs used are also registered, it will be pos¬ sible to have the information-carrying card serve as a so- called 'drug card' as well, and even as a prescription. It need not be argued that many errors which occur at present and hospital admissions which are the consequence of these errors, might be avoided. Another advantage could arise if the information-carrying identification card contained data concerning the in¬ surance package of the patient and data as to whether or not there are general or specific personal liabilities, so that the care provider, by obtaining the permission of the care provider to carry out a certain order of care treat¬ ments, will also have a guarantee that the care provider will be paid for his exertions. Cards and equipment which can be used for the purposes stated above are known in themselves. They could, for instance, be so-called smart cards, optical cards of magnetic strip cards, or a combination of these, which can be read in and out by equipment which is for sale in the shops. Because some goods are provided with standardized barcodes, the reading equipment should be able to read barcodes as well. This equipment can be coupled to per- sonal computers in a known way. Some embodiments of the invention will be described by way of examples by means of the accompanying drawing, in which: Figure 1 shows a structure of the computer programme to be used in the method and the system according to the inven¬ tion, Figures 2A en B, respectively, show the front and the back of a patient identification card, and Figure 3 shows a schematic process chart of a care insti¬ tution. As represented in figure 1, the computer programme 3 uses central data files 2, containing information about the means at the disposal of the care institution. All means are present in the form of variabels. Examples of these means are: - diagnostic codes - therapeutic codes - available locations for care treatments - available equipment - available goods - available medical and care means - available staff - management The variabels are rendered interdependent, in as far as this applies in the care institution concerned, and/or provided with specific preconditions (such as for instance care workers who work specific hours and can therefore generate different costs) . All variables possess a code to which a length of time and costs per unit and price per unit are coupled. This interdependence leads to a collec¬ tion of possible processes which together represents the care package offered by the care institution in the shape of a process flow which can be passed through by the patient. .An example of this is represented in tabel 1. Each process starts with reading the patient iden¬ tification card 5 (figure 2) . This has a module 6 with the following data in indelible form: a. an identification number consisting of a main number and a serial number which are composed as follows: - for residents with a personal national insurance number the main number is the national insurance number and the serial number is zero. - for residents without a personal national insurance number, the main number is the national insurance number of the natural person or legal body which represents them (for instance parent, guardian, curator, government insti¬ tution) and the serial number is between 1 and 999999999 (children, inhabitants of special institutions) . for non-residents, the main number is the national insurance number of the domestic authority responsible for him or an identification number of a foreign authority and the serial number is between 1 and 999999999. This would include, for instance, centres for persons seeking asylum, foreign travel insurers or countries. Each care provider is handed their own serial numbers for these cases. These numbers can also be used in those cases in which, for some reason, residents are (temporarily) not in possession of their card and in which immediate medical treatment is imperative: a so-called wild card. b. the blood group of the patient, possibly complemented with other unvarying data such as tissue typification, finger print, DNA-code, allergies or specific disorders. c. an access code consisting of, for instance, 10 digits. After reading module 6 , the computer programme 3 genera¬ tes an output signal (i.e. the key/password) by ' which other modules, for instance 7, 8 and 9 of the patient identification card 5, become suitable to be read by the computer programme 3. The content of these modules 7, 8 and 9 can be altered by the patient and/or an authorized person. These further modules 7, 8 and 9 could for instance contain the following data: Donor code and other information connected with this as well as other expressions of a person's will, such as authorized persons, euthanasia, etc. Data concerning the insurance package, such as the name of the insurance company, the policy number, the standard package, the presence of general and specific personal liability, supplementary packages, etc. Data concerning facts and conclusions of care treatments that have already been received or have yet to be carried out as well as concerning medication (drug card) . Data concerning care treatment in home care situations by for instance general practitioners and paramedics. Data intended for assessing quality and for the medical insurance of the patient. Data intended for other purposes. After the patient identification card has been read, the patient authorizes the carrying out of an order of care treatments relating to himself. The nature (of the treatment) , in the form of a code or combination code, constitutes the input fed to the computer programma by a care provider or by variable modules of the patient identification card. The latter is the case if this information was already stored in these modules as a consequence of a previous programme output. Subsequently, the programme generates the following data 4 according to the schedule concerning the order of care treatments represented in figure 1: A. Locations where the care treatments will take place. B. Starting times of the care treatments C. Estimated finishing times of the care treatments. D. The names of the care workers required for the care treatments. E. The required aids and goods. F. The required medication. G. The required number of hours of each care worker per care treatment. H. The times at which each care worker should be in a certain place. I. The costs of the number of hours per care worker. J. The costs of the aids per care treatment. K. The costs of the medication per care treatment. L. The costs of the equipment per care treatment. M. The costs of the location per care treatment. N. The total costs of the order of care treatments. 0. The price to be charged for the order of care treatments provided. P. Possible references for subsequent care treatments (medication, etc.). Q. Possible follow-up appointments. R Z The nature of the order of care treatments is filed in the medical file of the patient in the file of the main memory in codes or a combination of codes together with possible particulars or remarks made by a care provider. At the same time, A - F and 0 - Q are also filed in this file. The patient receives a print-out of a part of the output (A., B. , C. , 0., P., Q.,) as well as of the nature of the order of care treatments, while this information is also stored on a module of his patient identification card. Since the data under H. are stored in the files intended for this purpose, a planning for each care provider will be available immediately. In practice, the care provider could receive a print-out of this information once a week, so that he will be in possession of his schedule before the working week starts. It will also be possible for him to gain access to this file by means of a personal pass word, so that he can see what his schedule looks like at any given time. Because the goods, equipment and drugs to be used (E. , F.) as well as the quantities thereof are filed in specific files (see figure 1) and because the system also knows what the minimum amounts per item should be (the so-called critical stock) , the computer programme also generates the information as to at what time a specified amount of a certain good, aid of drug should be ordered. In this case too, this can be followed up by a letter being sent to the person responsible for purchases, or the person can read this for himself in the files concerned by means of a pass word. In this manner, the system can manage the stocks and supplies. Due tot he fact that the system retains all data concer- ning care treatments, it is possible to use the system as an instrument for forming a judgement on the quality of care offered per care provider, per ward, per piece of equipment, per location, etc. The patient has access at all times to his own medical file, so that he will not need permission for this from the care provider. The patient himself owns this file. The system reveals the codes stored on the patient identi- fication card, so that the system as it were manages the file for the patient. If the patient dies, it will be possible to learn from a module of the patient identification card, whether care treatment should be planned in relation to donorship. Because another module can contain the insurance data, it will be possible to determine the costs of certain care treatments before they are carried out and also before reading the card for the benefit of planning. It will also be possible to determine how much of the costs will be paid by the insurance company and how much the patient will have to pay himself. These data could lead to a preference for different care activities, thus enlarging the range of options for the patient. After permission has been given and the data have been stored, the price of the care offered can immediately be stored on this module or, if desired, on paper. Payment can then take place immediately after the last care treat¬ ment by the patient or his insurance company. At present, payment does not take place until at least 60 days after the last treatment. Although the shape and quality of the patient identifi¬ cation card is such that it can easily be carried around by its owner, there will be patient identification cards of the wild card type for non-residents in each institu¬ tion and in each mobile care unit. The process chart of the optimization programme to be used in the method and in the system according to the inven¬ tion, will be described by means of figure 3. A number of days before the patient is admitted, the main coordinating department will have at its disposal all the capacity still available. Then, it will have to be deter¬ mined how much capacity will be available on the day of admission, taking into account appointments that have been made and expected urgency. A selection will also be made of those patients who are available on that admission day. This selection will also include patients who are on the waiting list. Moreover, it will already be known which patients have indicated that they will be available, should they be admitted earlier. This last group is selec¬ ted on the basis of criteria of the medical specialist. Now, both the availability of capacity and the demand for this capacity are at the disposal of the people concerned. Mathematically formulated one is faced, when drafting an admission programme in which these two elements of supply and demand are combined, with a problem with a linear goal function, non-linear preconditions and binary variables. The admission programme will have to meet the following requirements: - sufficient capacity for patients urgently requiring care, - patients requiring semi-urgent care have to be admitted within the time set, - remain with the preconditions of the capacity, - the longer on the waiting list, how higher the priority (semi-urgent typification) , - patients should not be forgotten (especialy the internal transfers who are often less urgents, but who should not be dismissed between treatments, - capacity bottle-necks should be used to the best pos¬ sible advantage. The programma works as follows: 1. sort the list containing available patients on the basis of priority, (this leads to sorted list 10) The patients having the highest priority are these requiring semi-urgent care. Within this group, a fur- ther selection can be made on the basis of the length of time a patient has been on a waiting list. It will also be possible to sort the remaining patients per specialty on the basis of the length of time that they have been on the waiting list. 2. Fill up the time available in the operating theatre and the available beds per specialism with patients appearing on the sorted list in order of priority. In doing this, attention should be paid to the dif¬ ference between beds in male and female wards. The following situations can arise: - the beds available are filled, but there is still time available in the operating theatre (11 yes) - the time available in the operating theatre is filled up but there are still beds available (11 no) In the first case, a smaller operation will be replaced by a bigger operation (12) . This can be done in the following way: the operations can be divided into three groups on the basis of duration, operations of a short, medium or long duration. Out of the sorted list of patients, the patient with the lowest priority who is to undergo a small operation is selected. This patient is replaced by the patient who has not yet been selected, who has to undergo a long operation and who has the highest priority. In the second case, no action takes place at yet. ^^ 3. -allocating the selected patients to^the wards. First of all those patients are placed who can only be helped by one ward (13) . The remaining patients are sorted on the basis of the workload they generate, in decreasing order. For every ward where beds are still available, the remaining available workload (15) is calculated as indi¬ cator. Patients who already have an appointment for the admission day concerned, can also be included in this placement procedure (16) , but care should be taken to ensure that they are admitted in any case. 4. Solution in case of workload problems (18) when all patients have been placed (17) . When the agreed limits are exceeded, serious patients will have to be replaced by patients requiring less care (19) , or one should see where there is any capacity left. If; apart from workload, a bed is available, too, a reshuffle may suffice. If not, a patient requiring a great deal of care will have to be deleted from the list of admissions (20) . Time in the operating theatre which thus becomes available (21) can be used by a patient who puts less of a strain on the workload. Apart from that, all sorts of combinations can of course be considered. 5. filling up remaining capacity (23). If there are wards who have both beds and nursing capacity available, these can be used by admitting patients who do not have to undergo surgery. It will also be possible to replace a lengthy operation by two shorter operations. Selecting a certain option will depend on the relative priority of the patients. The heuristics described above are applied in hospitals where the available time in the operating theatre is considered to be a bottle-neck. This time is namely filled in first. Then, the capacity of beds is looked at, and last of all the nursing capacity. The latter is by no means the least important. However, practice has shown that the nursing capacity provides most opportunities for shifting. In this way, the programme results in an optimal use of the available time in the operating theatre within the preconditions set. In a practical example the application of the inventive method and the inventive system can generate the following data for the person concerned: The patient. A patient visiting the clinical consulting-hour receives the following letter at the end of the consultation, with the following contents: 1. Dear Sir/Madam, date and diagnosis 2. Date of admission, time of admission, ward room, 3. Day of operation, time of operation, surgeon, 4. Day of discharge and time of discharge 5. Persons responsible for treatment, care and service 6. telephone number of the admissions department in case of eventualities 7. Visiting hours 8. Complaints procedure and kind regards from the manage¬ ment. The surgeon On a weekly, and if necessary on a daily basis, the sur¬ geon receives a survey from the admissions department, containing the following information: 1.

The system is very user-friendly because it minimizes many activities which are at present a constant source of irritation to the staff. These effects are aimed at moti¬ vating the staff to switch over from a product/production oriented style of work to a market/client-oriented style. Time will become available for staff to concentrate on the essentials of their work. The amount of time gained comes from drastically reducing administrative procedures, reducing the number of useless actions and reducing the understaffing of the staff (and patient) . The invention has the following effects on the following groups of people concerned: The nursing wards The all or nothing effect (one of the main causes of the high level of sick leaves and disablement) is eliminated by: - the number of patients to be admitted for pre and post operative care and non-surgical care will always fit within the hour profiles agreed upon. - a shortage of shifts is regulated by a revised hour profile. - a surplus of shifts can be used to raise the hour profile. - the entitlement to the number of days off in a calendar year is regulated by the admissions depart- ment. - the time-consuming activity of looking for files is a thing of the past. The file will always be where the patient is. The medical activities departments. - the number of patients to be admitted for pre and post surgical care and non-surgical care will always fit within the hour profiles agreed upon. - a shortage of shifts is regulated by a revised hour profile. - a surplus of shifts can be used to raise the hour profile. - the entitlement to the number of days off in a calendar year is regulated by the admissions depart¬ ment. - the patient will always take his medical file with him. In this file, it will be automatically recor¬ ded that the medical activity has taken place. The specialist - optimizes his dedication for the benefit of the patients. - experiences a drastic lessening of the burden of administrative procedures. - will be more service-oriented towards his patients because it will be possible to immediately make sug¬ gestions for a programme of action and to record such a programme. - will be in possession of the medical files prior to his consulting hour so they will no longer have to be traced. - will receive a quality judgement after each se- quence of care treatments, so that he will be better able to inform the patient beforhand - it will be possible to get rid of 'soft' waiting lists. Therefore more service for the patient. - it will be easier to get rid of 'hard' waiting lists because it will be possible to use additional facilities which become available because other spec- ialists temporarily have less patients - applications for more means, if necessary, will now be automatically supported quantatively. - less negative energy needs to go into supposed favouratism because it is not a person but an 'objec- tive' programme which is carrying out the optimi¬ zation process. - optimizing heightens the chance of a higher fee per ' time unit. - immediate insight into costs and yields per patient or group of patients, so that one will be better able to choose between competitive examinations. The management. - The management will now be able to feed production agreements such as nursing days, admissions, medical activities, operations, visits to the clinic etc. into the programme, which production agreements can now indeed be realised by means of planning. - the management will receive concrete and manageable information concerning costs and yields per opera¬ tion/diagnosis and concerning products and statis¬ tical data on all possible variables. - the data will enable the management to pursue a strategic management style, which is necessary in a health care sector which is being subjected to more market forces. -the management will possess the necessary infor¬ mation to be able to realise a policy plan in a com- petitive market by conducting well-directed negotiat¬ ions with care insurers. Although the invention is described above by means of the medical sector, it will be obvious that the invention can also be successfully applied in other social sectors. In relation to the patient identification card, it is observed that the access of the card to the computer programma can not only take place via an access code represented in digits, for instance magnetic, optical or bar code digits, but that this can be done in many dif¬ ferent ways. It is possible for the card to have an access code in the form of a coating which only reflects light in a certain colour, in the form of a coating which becomes transparent in a certain electro-magnetic field, in the form of a surface of the card having a certain roughness, in the form of a certain form of outline of the card or for instance in the form of cut-away sections in the card.

Claims: C A I M S 1. Method for patient-oriented optimization of orders of care treatments offered by a care provider, comprising: - the reading of an access code by a computer programme loaded into a computer, said access code being incor- porated into a module of indelible data on a patient iden¬ tification card, - the generating of an output signal following the posi¬ tive identification of the access code of the patient identification card by the computer programme, - the reading by the computer programme of variable data which have been rendered accesible hereby on the relevant modules of the patient identification card, - the processing of central data files filed in the main memory of the computer by the computer programme, said files concerning the care activities and/or the patient, and processing the data read on the patient identification card in such a manner that an order of care treatments is generated which is optimally patient-oriented, and - the up-dating of the variable data on the patient iden- tification card and up-dating the central data files after the care treatment. 2. Method according to claim 1, characterized in that generating an optimal patient-oriented order of care treatment takes place in such a way, that the patient is placed on a waiting list of patients, that the computer programme sorts the waiting list in order of priority on the basis of patient data, and that, on the basis of the patient data and the central data files, it renders the care treatments mutually dependent to such a degree that the length of time between the first and the last care treatment of the patient is minimized and the degree of utilization of all means at the disposal of the care provider are maximized in their mutual dependance as defined by the computer programme. 3. Method according to any one of the preceding claims by which data concerning the state of health of the patient and the care treatments he is receiving are collected and managed, wherein these data are the property of the pa¬ tient and are accessible to the patient alone in a certain place by means of his patient identification card, regard¬ less of the fact that these data originate from different care providers or various social workers. 4. Method according to claim 1 or 2, wherein the patient authorizes the carrying out of an order of care treatments for himself by means of his patient identification card. 5. Method according to claim 1 or 2, wherein the sum total of the means and care treatments provided by the care provider is expressed in standard units of money, time, people and volume in such a way that a future order of care treatments for a patient will, after the patient has authorized it, determine the costs/price and duration of this order of care treatments. 6. Method according to claim 1 or 2, wherein measurable criteria are generated to ensure that injured parties can be compensated regardless of the question of guilt, and whereby the order of care treatments and the means can be geared to each other more efficiently. 7. Method according to claim 4, wherein the patient iden- tification card contains the care package for which the patient is insured, by which, through authorizing a future order of care treatments, a payment guarantee is given. 8. Method according to claim 1, wherein the patient iden¬ tification card contains erasable data for the benefit of a drug card, donor card, the expression of the patient's will concerning euthanasia, incompentence, etc. 9. System for patient-oriented optimization of orders of care treatments offered by a care provider to patients, wherein the degree of utilization of all means at the disposal of the care provider, which together with these order of care treatments constitute, in their mutual dependence, the care process, is maximized, comprising a patient identification card having a module with indelible - patient data and an access code and further modules with variable data, and a computer programme loaded into a computer to which the patient identification card has access by means of the access code, the computer programma having access, after the access code has been read by means of reading equipment, to the data filed on earlier modules and to central data files determined by this access code. 10. System according to claim 9 which collects and manages data concerning the state of health of the patient and care treatments he is receiving, wherein these data are the property of the patient and to which he alone has access by means of his patient identification card, re¬ gardless of the fact that these data originate from dif¬ ferent care providers or several social workers. 11. System according to claim 4, wherein the patient authorizes the carrying out of an order of care treatments for himself by means of his patient identification card. 12. System according to claim 5, wherein the sum total of means and care treatments provided by the care provider is expressed in standard units of money, time, people and volume in such a way, that a future order of care treat- ments for a patient will, after the patient has authorized it, determine the costs/price and duration of this order of care treatments. 13. System according to claim 6, wherein measurable crite¬ ria are generated to ensure that injured parties can be compensated regardless of the question of guilt, and by which the order of care treatments and the means can be geared to one another more efficiently. 14. System according to claim 7 and claim 11, wherein the patient identification card contains the care package for which the patient is insured, by which, through authoriz¬ ing a future order of care treatments, a payment guarantee is given. 15.
