Abstract:
The present invention is a system and method for inputting physician notes associated with the admission, diagnosis and treatment of patients in a healthcare system. It can be used for those who are critically ill as well as those who are engaged in more routine medical care. The present invention reduces the risk of medical treatment by populating specific patient information throughout the patient care system so that current physician notes are combined with other information and made available rapidly to hospital personnel at all levels of patient care. The present invention also assists in analyzing data in relation to risk associated with management choices and managing the patient care to reduce assessed risk.

Description:
CROSS REFERENCE TO OTHER PATENT APPLICATIONS  
       [0001]    This application is a continuation-in-part of and claims priority to U.S. patent application Ser. No. 09/443,072, entitled “System And Method For Providing Continuous, Expert Network Critical Care Services From A Remote Location(s)” filed Nov. 18, 1999, which is hereby is incorporated by reference in this application in its entirety for all purposes. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    The present invention relates to a system and method for automating physician notes within an entire system of patient care and patient monitoring. For purposes of this application, the “patient care system” refers generally to the system in a hospital or other care facility that provides health care services to patient. Such a system comprises, without limitation, emergency rooms, operating rooms, laboratories, hospital rooms, data processing systems, monitoring equipment, administrative systems and billing systems.  
           [0003]    While the severity of illness of ICU and other hospitalized patients over the past 15 years has increased dramatically, the level of and type of physician coverage has remained constant. Most hospitalized patients receive brief minutes of attention during morning rounds. During the remainder of the day and night, nurses are the primary caregivers, with specialists called only after patient conditions have started to deteriorate. One result of this mismatch between severity of illness and physician coverage is a high prevalence of avoidable errors that result in clinical complications. Exacerbating the problem is the inability of present days systems to incorporate and disseminate information derived from doctors and other hospital based physicians through the patient care system so that all observations and diagnoses are available to various hospital personnel in a timely way. In 1998, an Institute of Medicine Roundtable determined that avoidable patient complications were the single largest problem in medical care delivery. In another prominent 1998 study of 1000 patients, 46% experienced an avoidable adverse event in care, with 40% of these errors resulting in serious disability or death. Techniques that can limit these problems would be beneficial indeed, not only to patients but to the hospitals themselves.  
           [0004]    The physicians who treat critically ill patients are in critically short supply. Numerous studies have shown that intensivists (physicians who have trained and board certified in Critical Care Medicine) can markedly improve patient outcomes. However, only one-third of all critically ill patients ever have an intensivist involved in their care, and the number of intensivists would need to increase seven-fold (nationally) to provide 24-hour coverage to all critically ill patients. With the rapid aging of the population, this shortfall of expertise is going to increase dramatically.  
           [0005]    Even where intensivists are present (and especially where they are not), patients suffer from unnecessary variation in practice. There is little incentive for physicians to develop and conform to evidence-based best practices (it takes significant work and a change in behavior to develop and implement them). This variation contributes to sub-optimal outcomes, in both the quality and cost of care delivered to hospitalized patients.  
           [0006]    What is needed, and is beginning to be fielded with great success, is a critical care regimen offered to critically ill patients. Such a system is described in Application for Letters patent No. 09/443,072, entitled “System And Method For Providing Continuous, Expert Network Critical Care Services From A Remote Location(S)” which is incorporated herein by reference. Rather than the traditional consultative model where a periodic visit takes place and the doctor then goes away, a more active 24-hour intensivist managed care is instituted via remote monitoring of geographically disparate healthcare locations. Such technology leverages the intensivists&#39; expertise and standardizes the care afforded to critically ill patients. Further, continuous feedback to improve the practice of intensivists is necessary so that timely interventions can occur to minimize any adverse events. But even more can be done.  
           [0007]    Attempts to automate various aspects of patient care have been the subject of various inventions. For example, U.S. Pat.

           [0019]    While these inventions provide useful records management and diagnostic tools, none of them provides a comprehensive method for inputting physician notes and populating patient care databases in real time regardless of where and when those physician notes are generated. In short, the inventions noted above are NOT designed for highly integrated hospital care.  
           [0020]    What would be useful is a system and method for providing physician notes in a convenient manner, and integrating those notes throughput the patient care system whether it be for routine care or for care for the critically ill. Information from the physician notes (i.e. observations, thinking, and clinical plans for patients) would be immediately available to hospital personnel at all levels from administrative to those dealing directly with patients. Further, such information entered by a physician would be re-used to the maximum extent and in the most effective manner to provide information necessary for patient care and related administrative services.  
         BRIEF SUMMARY OF THE INVENTION  
         [0021]    The present invention is a system and method for creation and dissemination of Physician notes.  
           [0022]    It is an aspect of the present invention to integrate and coordinate diagnosis, diagnostic tests, treatment and monitoring actions and administrative functions with physician notes generated for any particular patient regardless of where the patient is in the healthcare system.  
           [0023]    It is another aspect of the present invention to capture important clinical data for a patient one time and to re-use that information repeatedly throughout the patient care system.  
           [0024]    It is yet another aspect of the present invention to automate recording of patient notes made in the course of patient care.  
           [0025]    It is yet another aspect of the present invention to provide physicians with formatted options for creating detailed notes and diagnoses that facilitate use of the physician notes throughout the patient care system and associated databases.  
           [0026]    It is a further aspect of the present invention to provide an automated system for communicating and coordinating the patient&#39;s medical history and treatment with a billing system.  
           [0027]    It is a yet a further aspect of the present invention to provide an automated system for communicating the patient&#39;s updated medical information with medical treatment devices providing therapy to the patient.  
           [0028]    It is yet another aspect of the present invention to help physicians detect patterns relating to temporal and contextual aspects of a patient that might otherwise go unnoticed.  
           [0029]    It is still a further aspect of the present invention to provide customized patient diagnostic menus based upon the patients medical history and treatment plan and provide/report that information to hospital personnel at all levels in the patient care system as appropriate (i.e. not all hospital personnel require ALL information about a patient).  
           [0030]    It is yet a further aspect of the present invention is an automated patient management system that records patient information and communicates the information to patient treatment stations to assist in administration of treatment and monitoring.  
           [0031]    It is another aspect of the present invention to customize the pull down menu provided by the system to reflect a patient&#39;s medical history, diagnosis and treatment options.  
           [0032]    It is yet another aspect of the present invention to automatically select and set patient alarm notifications and reminders to health care workers when a patient&#39;s medical treatment is due.  
           [0033]    It is a further aspect of the present invention to provide risk assessment of specified therapies and notify the health care providers when therapies specified to the system are contraindicated.  
           [0034]    It is yet another aspect of the present invention to respond to changing patient healthcare parameters by providing customized patient healthcare diagnostic and treatment menus specific for the changed state of the patient and to facilitate diagnosis.  
           [0035]    It is yet a further aspect of the present invention to customize pick lists of patient care options to reflect the health care needs that are appropriate for each patient.  
           [0036]    It is yet another aspect of the present invention to pre-load information for physician notes based upon prior notes so that further physician notes about a patient comprise information entered from prior notes thereby saving time in the note creation.  
           [0037]    It is still another aspect of the present invention to link ICD-9 codes and CPT codes to the physician note entries to provide billing information to administrative parts of the patient care system.  
           [0038]    These and other aspects of the present invention will become apparent to those skilled in the art from a review of the general and specific descriptions that follow.  
           [0039]    The present invention is a system and method for inputting physician notes associated with the admission, diagnosis and treatment of patients in a healthcare system. It can be used for those who are critically ill as well as those who are engaged in more routine medical care. The present invention reduces the risk of medical treatment by populating specific patient information throughout the patient care system so that current physician notes are combined with other information and made available rapidly to hospital personnel at all levels of patient care. The present invention also assists in analyzing data in relation to risk associated with management choices and managing the patient care to reduce assessed risk.  
           [0040]    The system and method of the present invention can be implemented in a general purpose computer or a portable computer. It is equally suitable for use on Tablet PC&#39;s and personal digital assistants (PDA&#39;s) and for both wired and wireless systems.  
           [0041]    The present invention provides physicians with a series of tools for creating detailed notes that document their findings and treatment plans. The note writing application of the present invention provides physicians with tools for creating detailed notes that document their findings and treatment plans. Through the use of physician notes and integration functions, clinical data is captured and re-used throughout the patient care system. By incorporating physician observations, assessments and plans into a patient care database, these data enable the intelligent systems that comprise the patient care system to provide more focused care and avoid errors that might otherwise occur. This, in turn, enhances the efficiency and effectiveness of patient care and resulting in superior clinical outcomes.  
           [0042]    The note writing application of the present invention is available for use by any on-site physician. The present invention comprises templates for multiple different types of physician notes, including admission notes, brief and comprehensive progress notes, procedure notes and consultation notes. The note writing application uses a series of data-entry screens that break the notes into discrete sections. The bulk of the data are entered into the note using pre-defined selection options (e.g. pick list items, radio buttons, etc.). This both speeds note creation and captures discrete data elements, each of which relates to a specific patient at a specific point in time. The formatted nature of the data input by the physician are also easily accepted into the patient care database. All entries are time stamped by the present invention when they are released by the physician.  
           [0043]    Over 1000 structured data elements are available for the physician note creation, covering admission data (demographics/admission date and time/admission diagnosis/past history/social history/family history/review of systems), physical examination findings, active diagnoses and treatments, and details of specific procedures). However, the number of entries is not meant as a limitation. It is anticipated that the number of formatted entry options will increase as knowledge of various treatments are added to the medical community generally. Free text fields are provided to allow entry of information not captured in the pick list options and for narrative detail, where needed. Conventional means such as keyboards, handwriting recognition, and voice recognition can be used for free text entry.  
           [0044]    The end product of the note writing application of the present invention is a file that presents the selected options and free text entries in a format resembling a traditional physician&#39;s note. This file is stored electronically, after being signed electronically by the physician, for subsequent review within patient care system and can be configured to print a copy of the file for inclusion in the medical record or to export a file to hospital information systems. The note writing application is designed to provide substantially all required physician documentation options that a physician might normally need for creation of a patient record. The present invention can also be upgraded to add more options to the various note writing screens as more knowledge is gathered about patient care.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0068]    As noted above the present invention is a system and method for providing a physician note writing functionality that is integrated into a patient care system. The present invention provides the physician with a wide variety of formatted patient related input options normally used by the physician in admission, diagnosis, physical finding and other factors. Once released by the physician, the patient notes are populated throughout the patient care system to aid in patient care, set alarms for patient physiological data, and to monitor best practices to name but a few functions. Physician notes, and the data contained therein, are also re-used and released (as appropriate) to administrative functions of the patient care system such a billing (ICD-9 and CPT codes), insurance form completion, Medicare and Medicaid aid requests and the like.  
         [0069]    [0069]FIG. 1A illustrates a block diagram of functional areas receiving data from patient notes according to an embodiment of the present invention. The physician data entry produces a body of data referred to in FIG. 1A as “Notes.” A subset of notes data is available to populate other administrative functions relating to the patient&#39;s care and the administration of the paperwork associated with that care. As illustrated in FIG. 1A, these functions comprise:  
         [0070]    Medication Administration. Data fields as to allergies, pre-admission medications, and prescribe medications are populated.  
         [0071]    Pre-fill subsequent notes. Data fields regarding the patient that have been previously completed are pre-filled automatically in subsequent notes.  
         [0072]    Patient Profile Screen. Note data are added to the patient profile information (e.g., active diagnoses and treatments).  
         [0073]    Event Log screen. Basic patient data is added to the event screen.  
         [0074]    Line Log screen. Note data are used to create/maintain the line log from physician procedure notes.  
         [0075]    Severity Adjustment. Note data are used to populate severity adjustment tools (e.g., APACHE™ II or III scoring). The severity adjustment score is returned to the patient profile.  
         [0076]    Billing (physician and hospital). Note data comprise all of information necessary to determine the charges for a patient.  
         [0077]    Set Alerts (e.g., Smart Alerts™). Physician-entered data (active diagnoses and past history) automatically configures “smart” diagnostic systems to thresholds relevant to a particular patient allowing automatic monitoring of both absolute value and trends in those variables.  
         [0078]    Identify Diagnoses. A diagnosis pick list is displayed in response to note data.  
         [0079]    Identify Treatments. Customized patient healthcare diagnostic and treatment menus are displayed in response to note data.  
         [0080]    Reporting Practice Patterns (e.g., Smart Reports™). Reports are created from the notes data. These reports profile how care is delivered— providing information not normally available to hospital administrators or physicians.  
         [0081]    Following are more detailed descriptions of the options and actions presented to the physician by the present invention:  
         [0082]    In accordance with a first aspect of the present invention, as embodied and broadly described herein, FIG. 1B illustrates completed admission note data. “Notes” are an important function of the integrated system of data management. In one embodiment of the present invention, a physician enters information about a patient as Notes. As illustrated in FIG. 1B, the Notes-Create button enables a physician to create physician notes that are recorded in a database of the patient care system. Data entered into Notes are used to populate other areas of the patient care system, such as the patient profile.  
         [0083]    Five types of Notes are illustrated in this FIG. 1B. However, this is not meant as a limitation. Other types of notes are easily added as healthcare knowledge increases:  
         [0084]    1. Admission Notes Admission Notes are required for each patient upon initial admission to the hospital or ICU. The system does not allow entry of a Comprehensive Progress Note until the Admission Note has been completed. One Admission Note is entered per initial visit to the hospital or ICU.  
         [0085]    2. Readmission Notes are required for each readmission to the hospital or ICU. The system does not allow entry of a Comprehensive progress Note until the Readmission Note has been completed. One Readmission Note is entered per readmission to the hospital or ICU.  
         [0086]    3. Comprehensive Progress Notes provide the physician with a means of tracking and documenting a patient&#39;s progress.  
         [0087]    4. Brief Progress Notes Provides the physician a means of documenting events in a patient&#39;s progress.  
         [0088]    5. Procedure Notes provide the physician a means of tracking and documenting procedures that were performed on a patient.  
         [0089]    There are two types of Admission Notes: Medical and Surgical. The procedures for admission in each setting are different. In another aspect of the present invention, a surgical admission note is used for a patient that was admitted or came from the operating room (O.R.) in the past several hours. An Admission Note can be cancelled from any of the screens in the Create Note process by clicking the Cancel button. Options are provided to the user for closing the note or selecting the “Yes” button to go back to the Types of Notes screen. Selecting the “No” button returns the user to the current Admission Note.  
         [0090]    An embodiment of the present invention is creating an admission note for a patient who was not admitted to the operating room before admission: selecting the Notes-Create button from the Patient Profile screen provides data fields for entering data as to the admitting Diagnosis. When a patient is admitted to the hospital or ICU as a medical patient, the user completes the Admitting Diagnosis fields by using the pick lists. Data is entered as to complete the Chief Complaint/History of Present Illness data fields. Data is entered as to the Source of Patient Information from a pick list.  
         [0091]    Yet another aspect of the present invention is creating an Admission Note for a surgical patient. To create an Admission Note for a patient who was admitted to the hospital or ICU from the operating room, a user selects the Admission link. Data is entered in the required surgery fields as to the Surgical Diagnosis, the organ system involved (selected from the pick lists), the required elective surgery, and the Surgical Diagnosis fields selected from the pick lists. The Diagnosis pick list is displayed in response to the admission note populating the surgery fields. Data is entered to complete the Post-Operative Status information. Data as to the Chief Complaint/History of Present Illness is entered from the Source of Patient Information pick list.  
         [0092]    Data fields as to Allergies and Pre-Admission Medications are populated from the Allergies and Pre-Admissions Medications pick lists. The Allergies and Pre-Admission Medications menu displays the Select Drug(s) screen. The present invention also checks for drug allergies and contraindications for any drug and conveys to the physician any such drug allergy or other indications that may be stored concerning the patient.  
         [0093]    [0093]FIG. 4 illustrates data fields populated as to allergies and pre-Admission medications. In one embodiment data are entered from the Allergies and Pre-Admissions Medications pick lists when applicable. Data as to drugs prescribed to the patient and drugs taken by the patient are entered from a Select Drug(s) screen.  
         [0094]    [0094]FIG. 5 illustrates one aspect of a Select Drugs(s) screen. Once the relevant drug is selected, the name of the drug can be typed in or selected form a list. The selected drug is added to the List of Drugs Selected for this Patient on the right side of the screen. Multiple drugs can be added by repeating the selection process until all the appropriate drugs are added. Data as to a non-drug allergy may also be entered. Data as to Pre-Admission Medications is entered in the Select Drugs field. As illustrated in FIG. 5, the relevant drug from the left side of the screen may be added or removed from the patient list. The name of the drug or use the mouse to scroll and select the name of the drug. Dosage, units and frequency for preadmission medications are entered in the medication field.  
         [0095]    A patient&#39;s Past History is also viewable in the present invention. The Past History information fields are displayed for population by data entry for procedures Performed and Not Performed, where information is or where information is not obtainable or where no health problems exist. Data entered as performed permits the user to enter past history information and access the past history menu. This is the default setting. Once data as to the Past History is entered, the user enters data as to at least one Past History field. All Past History fields are optional and should be completed as appropriate for each patient.  
         [0096]    Data entry for past history fields is optional. If data is entered, the user enters information as to the status of Neurologic, Cardiovascular, Pulmonary, Renal, gastrointestinal, Infectious Disease, Hematology/Oncology, Endocrine, Rheumatic, systems. Data entries will generate custom pick lists with additional fields to complete for data entry.  
         [0097]    For example, selecting Yes for TIA(s) causes the system to display a pick list titled “multiple” to allow you to indicate multiple TIA(s). As Past History information is added, you can show and/or refresh the Past History Summary, which displays a separate window showing the Past History as it will appear in the final printed Note.  
         [0098]    To enter a patient&#39;s Past History information: A user selects the desired section button (e.g. 1-Neurologic) in the Past History menu or uses the scroll feature on the right side of the screen.  
         [0099]    [0099]FIG. 7 illustrates the Patient History Summary displayed as the Patient History Summary in a separate window. This summary displays for the physician summaries of various conditions of the patient such as past medical conditions and individual habits such as smoking.  
         [0100]    [0100]FIG. 8 illustrates aspects of the review of systems fields to be populated. A user in the Review of Systems field selects either Performed or Not Performed. A user navigates the Review of Systems fields by selecting the appropriate menu buttons on the left side of the screen. As each menu button is selected, the information fields displayed on the right change so that only those fields that are associated with each menu appear. Highlighting a selection will notify the user as to which selection is being considered. Selecting the Performed button permits you to enter Review of Systems information and access the Review of Systems menu. If Review of Systems is performed, the system requires completion of at least one “Review of Systems” field. The “Review of Systems” information fields are: General Systemic, Eye, ENT, Cardiovascular, Respiratory, Gastrointestinal, Musculoskeletal, Skin, Neurologic, Psychiatric, Endocrine, Hematologic. Throughout Review of Systems, certain pick list selections will cause additional fields and/or pick lists to appear as necessary to complete data entry. As Review of Systems data is added, a physician can show and/or refresh the Review of Systems Summary, which displays a separate window showing the Review of Systems as it will appear in the final printed Note. All or some of the Review of Systems information can be entered.  
         [0101]    An exemplary approach to patient management utilizing the one embodiment is the following: Select General System in the Review of Systems menu. Select the necessary information from the pick lists. After all necessary Review of Systems information has been entered; the Review of Systems Summary is refreshed. This displays the Review of Systems Summary. FIG. 9 illustrates the Review of Systems Summary screen.  
         [0102]    The Social History and Family History display has two options 1. Performed and 2. Not Performed. The Performed option is the one option that permits a physician to enter Social History information and access the Social History pick lists. The performed option is the default setting. This is also true for Family History. Throughout Social History, certain pick list selections will cause additional fields and/or pick lists to appear as necessary to complete data entry. Selecting Not Performed removes all Social History information on the screen. This is also true for Family History. In Social History, the patient&#39;s marital status is derived from ADT information. The patient&#39;s smoking status, ethanol use and IV drug abuse information are derived from the patient&#39;s Past History information. Any changes in Social History information are reflected in Past History. Data as to the patient&#39;s Social History information is selected from information from the pick lists. FIG. 10: illustrates data entry fields where Social History/Family History screen information can be entered.  
         [0103]    The Physical Exam data fields have two options: 1. Performed and 2. Not Performed. The Performed option is the only option that permits you to enter Physical Exam information and access the Physical Exam pick lists. Selecting Not Performed removes all the Physical Exam information on the screen and the menu on the left side of the screen. The Physical Exam data fields available for population are Constitutional, Neurologic, Eyes, Ears/Nose/mouth/Throat, Neck, Respiratory, Cardiovascular, Relevant hemodynamic Data, Gastrointestinal, Genitourinary, Musculoskeletal, Extremities, and Skin  
         [0104]    [0104]FIG. 11 illustrates physical exam data fields. Data comes into some of the data fields based upon the bedside monitors for the particular patient. Data is also entered into the Physical Exam fields by selecting the appropriate options on the left side of the screen. As each menu button is selected, the information fields displayed on the right change so that only those fields that are associated with each menu appear and are highlighted in yellow. Throughout Physical Exam, specific pick list selections cause additional fields and/or pick lists to appear as necessary to complete data entry As Physical Exam information is added, a user can show and/or refresh the Physical Exam Summary. The following pertinent data are listed in the Physical Exam data fields: Constitutional, Non-Invasive, Mean, Defaulted, from most recent 10-minute median, near non-invasive arterial blood pressure value in Vital Signs, Systemic Mean Defaulted from most recent 10-minute median, near PA blood pressure value in Vital Signs, PA Mean Defaulted from most recent 10-minute median in Vital Signs, Heart Rate Defaulted from most recent 10-minute median in Vital Signs Temp Defaulted from Temp Max entry in I &amp; I.

         [0109]    [0109]FIG. 14 illustrates the fields, Billing Information screen. A user enters billing information” and is presented with a pick list. If no billing information is entered, this data field is not populated and completes the screen.  
         [0110]    [0110]FIG. 15 illustrates an Admission Note. The Admission Note screen provides a user view, sign, and print options. The admission note must be signed before it can be saved or printed.  
         [0111]    To sign a note and print the note in the ICU: a user must enter their P.I.N. and save button. To sign and save a note without printing, a user can sign a note that is entered under a different user&#39;s logon by entering a user&#39;s name, password, and authorized clinician&#39;s PIN.  
         [0112]    Another aspect of the present invention is the management of patients who are readmitted to an ICU Facility. Another embodiment provides for a user to create a readmission note for a patient to be entered into the ICU. The Readmission Note consists of ten screens:  
         [0113]    1. Reason for Readmission, Surgical information, Admission Diagnosis, Chief Complaint/History of Present Illness  
         [0114]    2. Allergies, Preadmission Medications  
         [0115]    3. Past History  
         [0116]    4. Review of Systems  
         [0117]    5. Social History and Family History

         [0121]    9. Billing information  
         [0122]    10. View/Sign/Print Note.  
         [0123]    The patient is a surgical patient when entered from the O.R. or went to the O.R. within 4 hours from admission. When the patient is admitted from the O.R., the note displays a Surgical Admission Diagnosis and data fields in which to record relevant post-operative information. When the patient is not admitted from the O.R., the patient is a Medical Admission and a Medial Admission Diagnosis data field is displayed.  
         [0124]    Another embodiment of the present invention is the Readmission note that can be either surgical or medical. Readmission Note (Medical) describes the procedures for creating a readmission note for a patient who was admitted to the ICU directly. Admission Note (Surgical) describes the procedures for creating a readmission note for a patient who was admitted to the O.R. before admission.  
         [0125]    A readmission note for a patient who is not admitted to the O.R. before admission is a medical readmission note. The user enters an admitting Diagnosis with the Reason for Readmission from the pick list. The Admitting Diagnosis fields are selected from the pick lists. The program contains a data field for the Chief Complaint/History of Present Illness. The user selects the Source of Patient information from the pick list. When a readmission is via the O.R., the readmission is classified as surgical. To create a readmission note for a patient who was admitted to the O.R., before admission into the ICU, the user specifies that the patient is admitted from the O.R.  
         [0126]    [0126]FIG. 17 illustrates a Surgical Diagnosis data field. The user enters data as to the diagnosis and selects options from the pick list to populate the remaining data fields. Data from the previous Admission note populates sub data fields in the surgical diagnosis screen. This can be edited if new information has been obtained since the last admission. The procedure for completing the sub data fields is the same as for the procedure for populating the Admission Note data fields.  
         [0127]    A Comprehensive Progress Note data field is not available to a user until an Admission Note section is saved. The Comprehensive Progress Note consists of 8 data (screens): Within each Data field are sub data fields that require population with patient specific data:  
         [0128]    1. Surgical Information, admission Diagnosis, Events of Note  
         [0129]    2. Allergies, Preadmission Medications  
         [0130]    3. Past History  
         [0131]    4. Physical Exam  
         [0132]    5. Today&#39;s Problems/Diagnoses, Today&#39;s Treatments/Diagnostics  
         [0133]    6. Laboratory Results, Assessment and Plan  
         [0134]    7. Billing Information  
         [0135]    8. View/Sign/Print Note.  
         [0136]    A Comprehensive Progress Note for new surgery data section provides instructions for creating a Comprehensive Progress Note for a patient who had surgery since the last Progress Note. There are a total of 8 screens in the readmission process A Comprehensive Progress Note created for a patient who was not admitted to the O.R. before admission.  
         [0137]    [0137]FIG. 19 illustrates a Comprehensive Progress Note data section. A user enters Events of Note information. The information entered when the Admission Note is created populates the same data fields in the Comprehensive Progress Note.  
         [0138]    A Brief Progress Note provides the physician with a means of documenting changes in patient status, updates and interventions. The progress note consists of 3 data fields: 1. Surgery question, Events of Note 2. Today&#39;s problems/Diagnoses, Today&#39;s Treatments/Diagnostics 3. View/Sign/Print Note. A user uses a Brief Progress Note for creating notes for a patient who has not had surgery since the last Progress Note. A Medical Brief Progress Note is used for creating a Brief Progress Note for a patient who has had surgery since the last Progress Note.  
         [0139]    To create a Brief Progress Note for a patient who has not had surgery since the last Progress Note. Selecting the Progress link and indicating that no surgery has taken place since the last progress note populates the surgery field. Data is Entered under Events of Note data field for random notes pertaining to the patient.  
         [0140]    To create a Brief Progress Note for a patient who has had surgery since the last Progress Note: the user selects the Brief Progress link and enters data as to the necessary Post-Operative Status fields. Data as to Events of Note information is entered in the free form field.  
         [0141]    [0141]FIG. 20 illustrates a Brief Progress Note screen. Modifications to data screens displayed on the Brief Progress note changes by navigating with the Previous button to go back to the screen(s) that require correction(s), making the necessary changes and advancing to the final screen. Thus the physician can change the active diagnosis and treatment based on the latest information about the patient. The Brief Progress Note is signed before it is saved or printed. By signing the note, the user authorizes updating the patient&#39;s chart with information from the Note.  
         [0142]    A note is signed by the user by entering a P.I.N A user can sign a note that is entered under a different user&#39;s logon: using the Sign As entry and entering the user name followed by the password and the authorized clinician&#39;s P.I.N. in the sign field. When the Brief Progress Note is Completed and signed, you save the Admission note by clicking the Save button. Print and save the Brief Progress Note by clicking on the Print and Save button.  
         [0143]    [0143]FIG. 21 illustrates a Procedure Note providing the physician with a Means of tracking and documenting procedures that were performed on a patient. The Procedure Note consists of two screens: 1. Procedure 2. View/Sign/Save Note. To Create a Procedure Note: the user selects the Procedure link and selects a procedure from a pick list. The procedures are listed as links. When a procedure is selected, additional links are displayed.  
         [0144]    A user can cancel the Procedure Note from any of the screens in the Create-Note process.  
         [0145]    [0145]FIG. 22 illustrates Procedure Note Specifics screen. A user enters the information from the pick lists. For example, when a user selects catheter insert a pick list displays the types the types of catheters the facility provides that the user selects. This displays the Procedure Note Final screen.

To make modifications to previous screens: the user selects the Previous button to go back to the screen(s) that require corrections(s). The user makes the necessary changes and advances to the final screen of the Procedure Note. Sign. By signing the note, the user authorizes updating the patient&#39;s chart with information from the note. Once this occurs, the present invention populates the various files that require such information such as billing systems, line logs, patient profile information and the like.  
         [0147]    A user signs a Note by entering a P.I.N. To allow one user to sign a note that is entered under a different user&#39;s logon: the user checks the Sign As box and enters the user&#39;s name, password, and the authorized clinician&#39;s P.I.N. in the sign field. When the Procedure Note is completed and signed, the user saves the note by clicking on the Save button. The user may print and save the Procedure Note by clicking the Print and Save button. A prompt is displayed to “wait while the note is printed and saved.” Another prompt notifies the user that “Your note has been printed and saved.” The Notes— View button enables a user to view a completed note including the date/time of every note. A note set is numbered and dated in reverse chronological date order, displaying the most recent note first for easy reference.  
         [0148]    [0148]FIG. 24 illustrates a Notes View screen a user can view any note by clicking on the note&#39;s time. When more than one note is shown, the user may view other notes by selecting the note to be viewed. The Note can be printed in the hospital, ICU, or the eICU facility. Notes that have been created and saved are displayed by time (newest to oldest) at the bottom of the Notes—view screen. The time is followed by letters that identify the type of note. These abbreviations are used: A—admission Note R—Readmission Note P—Procedure Note CP —Comprehensive Progress Note BP—Brief Progress Note  
         [0149]    As mentioned previously, the note writing application of the present invention is designed to capture clinical patient information for reuse within the patient care system. The following examples illustrate several ways in which present invention utilizes the data stored during physician note writing:  
         [0150]    Physician-entered data are populated within patient care system in order to place information in a context that facilitates patient assessment and monitoring. These data are often displayed with information obtained from other sources (or other notes), with the goal to portray patient information in a format that highlights temporal and contextual relationships and helps physicians detect patterns that may otherwise not be appreciated. Examples include the creation/maintenance of the Line Log from physician procedure notes and the display of active diagnoses and treatments on a Patient Profile.  
         [0151]    Physician-entered data (active diagnoses and past history) automatically configures “smart” diagnostic systems for specific patients. Examples include the automatic selection of more sensitive default thresholds for heart rate alarms in patients at risk for or suffering from active coronary heart disease and the identification of high-acuity patients without specified preferences for end-of-life support.  
         [0152]    Physician notes entered using the present invention are used to determine physician adherence to best practices and are used in reporting on patient care. Examples of such adherence that may be reported include the use of mechanical compression devices to prevent deep venous thrombosis, the detection of contraindications to the use of beta blockers, the presence of risk factors that increase predicted mortality, and many others.  
         [0153]    The capture of this granular, time-stamped information through the physician note writing system of the present invention therefore facilitates the use and administration other patient care devices and systems.  
         [0154]    It is also important to note that many of the physician notes are nested within data categories. Thus, information that is germane to a diagnosis or administrative function can be obtained readily depending on how the much a hospital personnel needs to “drill down” through such data. For example, it may be necessary for a physician to know that a patient has pneumonia AND to know the type of bacteria causing the pneumonia. However, a billing administrator need only know that the diagnosis is pneumonia. Other information about the specific pathogen causing the condition is NOT required. Further the present invention will provide only that information that is germane to the function being performed. Thus the billing administrator will not normally get the same information that the physician would receive, but only that which is necessary to do the administrative job.  
         [0155]    In another embodiment of the present invention, information that is acquired is used for severity-adjustment scoring of patient illness. By way of illustration and not as a limitation, information gathered by the present invention is used to determine an APACHE II score (which is well-known in the art). The APACHE II score is a general measure of disease severity based on current physiologic measurements age and previous health condition. The score can help in the assessment of patients to determine the level and degree of diagnostic and therapeutic intervention. Included in the score are values associated with acute physiology, age, and chronic health.  
         [0156]    In yet another embodiment of the present invention, data automatically configures “smart” diagnostic systems that provide the information for completion of the APACHE assessment. The same smart diagnostic systems alert administrator if there is insufficient data to provide an assessment. As will be apparent to those skilled in the art, other severity-adjustment assessment tools may be used with embodiments of the present invention without depart from its scope.  
         [0157]    Although the present invention has been described in terms of specific embodiments, various substitutions of materials and conditions can be made as will be appreciated by those skilled in the art. Further, while critically ill patients substantially benefit form the functions of the physician note writing applications of the present invention; this is not meant as a limitation. The present invention will find uses throughout the patient care system whether the patient is critically ill or receiving more “routine” medical care. Thus the description contained herein should be applied to all levels of patient care, whether the patient is in an institution for several days or is receiving outpatient care. In addition, the creation of physician notes need not occur at a fixed station. The templates for entering physician note information can be installed on portable computers, on PDA&#39;s as well as on more standard computer terminals found in hospitals. Similarly, a physician does not have to be “wired” to the servers of the present invention since the present invention can equally function in a wireless environment with physician PDA&#39;s or the like communicating in a wireless fashion with the patient care system. Thus the scope of the invention is only to be limited by the following claims:
