BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is broadly concerned with a system and method for conditional diagnosis, assessment and symptom tracking of patients having behavioral health and/or physical disorders. More particularly, it is concerned with a system and method for providing a health care practitioner with diagnostic criteria and assessment techniques for a particular disorder, recording a treatment plan, and tracking patient symptoms and responses to the treatment plan in order to assess, optimize and document symptom improvement under the treatment plan, as well as providing the patient and clinician with an education and interaction tool for facilitating communication between patient and practitioner regarding the nature of the disorder and purpose and progress of the treatment.
2. Description of the Related Art
Health care practitioners or clinicians voluntarily document observation and treatment of their patients so that they can monitor their treatment plans and make appropriate revisions to optimize patient symptom improvement. Such documentation is also required so that the quality of their care can be monitored by federal and state agencies, such as Medicare and Medicaid, and various private accreditation agencies, such as the Joint Committee on the Accreditation of Health Care Organizations. Clinicians also need to maintain adequate documentation in order to respond to requests from third party insurers for substantiation of patient claims for reimbursement.
Health care practitioners are trained to identify the symptoms of a patient, make a diagnosis of a disorder or disease, assess the severity of the disorder, develop a plan for treatment of the patient and track the progress of the treatment plan. To assist them in documenting these steps, clinicians generally dictate their notes of each patient visit. The notes are subsequently transcribed and maintained in a confidential record, or so-called “chart”. While the primary purpose of the chart is to assist the clinician with diagnosis and assessment of the patient's progress under the treatment plan, it also serves an important documentation function. Although the patient generally does not have access to the chart, information may be culled from it and provided to third parties such as insurance companies and various regulatory and accreditation agencies. Each of such third parties has its own documentary requirements, and any failure of the clinician to fully meet such requirements may result in negative consequences for both the clinician and the patient. For example, third party payors such as insurance companies frequently deny claims for reimbursement based on inadequate documentation of symptoms to support the diagnosis or progress under the treatment plan. And reimbursement may be denied for treatment which is expensive or long term in cases where progress cannot be demonstrated by familiar, objective methods, such as by laboratory testing.
In addition, such chart-type documentation methods produce a series of “snap shot” records of the patient's symptoms at each office visit. Over the course of treatment, the chart may become voluminous and time consuming for clinician review.
When a patient suffers from an injury or illness, a record of the patient's symptoms, diagnosis (whether the disorder exists), assessment (the severity of the condition once it is diagnosed) and the progress of the chosen treatment plan are relatively easy to document. However, when a patient suffers from physical symptoms having no observable underlying cause, or suffers from a disorder having behavioral or psychological symptoms, documentation of diagnosis, assessment and progress under the treatment plan can be substantially more difficult. Practitioners themselves may have difficulty tracking the effectiveness of treatment of such a patient.
In order to assist clinicians, various professional associations have developed criteria for use in establishing a diagnosis, conducting an assessment and evaluating the effectiveness of a treatment plan implemented by the practitioner. For example, the American Psychiatric association has developed the DSM-IV Diagnostic Criteria for Attention Deficit Hyperactivity Disorder (ADHD). A variety of diagnostic and assessment instruments have been implemented which employ such criteria.
Some instruments have been developed to assist in establishing a diagnosis, for example the Conners ADHD/DSM IV Scales. Some instruments, such as the Beck Depression Inventory, combine both diagnosis and assessment functions. Both of these types of instruments are generally in the form of questionnaires, which may be completed by a patient or by a health care practitioner during an interview with the patient. Such so-called self-reporting instruments include a set of predetermined questions which are answered by the patient. The responses may be forwarded to a testing center for visual or computerized scoring and the results returned to the patient's health care practitioner for interpretation. The responses may also be scored in the clinician's office. Alternatively, the health care practitioner may conduct a structured interview of the patient. As with self-reporting instruments, the patient's responses are scored and subsequently interpreted by the practitioner.
Once a conditional diagnosis and assessment have been made, the health care practitioner generally develops a treatment program consisting of prescribed medication and/or behavior management. Whether or not the diagnosis and assessment are conducted simultaneously and whether they are conducted by patient self-report or by structured interview, they provide a fixed record of the health status of the patient at the time the diagnosis and assessment are made. Some health care practitioners provide their patients with copies of the diagnosis and assessment scores. However, without clinical knowledge and experience, such scores generally provide a patient with little insight.
It is well known that the more targeted a treatment program is to a patient's own symptoms, the better the result. The effects of the treatment program on the patient's symptoms and development of any side-effects will determine whether the program requires modification. Thus, treatment is optimized by frequent periodic patient assessment during the course of the prescribed therapy. However, available assessment instruments provide one time, “snap shot” views, which are time consuming and require expensive subsequent scoring and analysis. Because they can only assess the patient's health status at the time of administration, they must be periodically readministered, scored and analyzed throughout the duration of the treatment program. Even then, the resulting multiplicity of scored assessment instruments in the patient's chart does not provide the clinician with a convenient, continuous summary of the patient's progress.
Some instruments, such as the Distressed Mood/Behavior Intervention Form have been developed for use as preprinted charts for institutionalized patients. These instruments are used by caregivers to document when a common behavioral symptom such as wandering occurs, the intervention, such as redirection, employed by the caregiver, and the initials of the caregiver observing the behavior. While such instruments provide a chart of patient behavior, they must be completed by the caregiver and do not include diagnostic and assessment criteria for any particular illness, or permit tracking of the patient's progress in response to a treatment program.
The diagnostic and assessment criteria for some disorders, such as ADHD, are complex and the assessment depends heavily on the patient's recollection. Consequently, a health care practitioner may have difficulty obtaining a complete record of all reportable factors, including symptoms, settings and frequency at every office visit. The complexity of the disorder may also leave patients confused and with unanswered questions about their disorder and their impairment may prevent them from organizing their thoughts during the brief office visit. Patients may also need general advice regarding alternative treatment options and where they can obtain additional information; or they may need more specific advice regarding how to keep track of their symptoms and communicate them to their health care practitioner so that complete information is provided. While patient care pamphlets are available to provide general information regarding many common disorders, they are not tailored to individual patients and they include no patient-specific symptom information. Patients generally receive little written information regarding their particular disorder and treatment plan and are provided with no written record of the initial assessment.
Accordingly, there is a need for a combination diagnostic and assessment tool that can be used as the basis for a dialog between a patient and practitioner during the office visit and which is aimed at tracking the patient's symptoms and targeting the treatment for those symptoms as they change over time. Such a tool is needed in order to document treatment progress for the clinician and the patient, as well as for third parties such as insurers and regulatory agencies. There is also a need for such a tool which is very easy to use in order to ensure that it will be used at every office visit. Regular usage of such a tool is necessary in order to track the progress of the treatment program so that the treatment can be promptly adjusted as necessary to optimize the outcome.
SUMMARY OF THE INVENTION
The present invention relates generally to a method for conditionally diagnosing a mental or physical disorder in a patient and assessing and tracking the symptoms of the patient during treatment for the disorder. The method involves providing an interview instrument implemented as a computer program, generating a screen display, and accessible and used by either or both of the clinician and the patient to record and track the symptoms, the interview instrument having a list of symptoms and diagnostic and assessment information for a selected disorder. A clinician conducts a first interview of the patient to identify and assess the patient's symptoms of the disorder in accordance with the list of symptoms and diagnostic and assessment information. The clinician then records the patient's symptoms and the clinician's assessment of the symptoms on the interview instrument. Alternately, the patient records the patient's symptoms on the interview instrument and the clinician then conducts a first interview of the patient. The clinician develops a diagnosis and treatment plan for the disorder and records them on the interview instrument. The clinician conducts one or more subsequent interviews of the patient for identifying and assessing the patient's symptoms; and the clinician records changes in the patient's symptoms on the interview instrument for documenting the effects of the treatment plan.
The interview instrument includes joint use, diagnostic, patient-use and follow-up portions. The joint-use portion includes a list of symptoms and assessment criteria and space for recording the patient's symptoms as well an assessment of the symptoms. The diagnostic portion includes diagnostic information for a preselected disorder as well as space for recording a treatment plan. The patient-use portion includes instructions for communicating with the clinician and educational information about the disorder. The follow-up portion includes the listing of symptoms as well as spaces for recording changes in the patient's symptoms over time, under the treatment plan.
Objects and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention.
The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.

DETAILED DESCRIPTION OF THE INVENTION
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.
Referring now to the drawings, FIGS. 10 and 11 depict a patient conditional diagnosis, assessment and symptom tracking method 10 in accordance with the present invention. FIGS. 1–9 depict an exemplary patient assessment interview instrument 12 for use in diagnosing patients with Attention Deficit Hyperactivity Disorder (ADHD). The interview instrument 12 includes a joint-use portion 14 (FIGS. 1–2 except spaces 50 and 52 and FIGS. 5–6), a diagnostic or clinician-use portion 16 (FIGS. 3–4 and boxes 50 and 52 of FIGS. 1–2), a patient-use portion 18 (FIG. 7), and a follow-up portion 20 (FIGS. 8–9).
Referring now to FIGS. 1–2 and 5–6, the joint-use portion 14 is designed for use by both the clinician and the patient. It includes identifying information in the form of a patient name space 22, a parent name space 24, date space 26 and a patient information space 28 for recording information relevant to diagnosis and treatment, such as age, grade, teacher, height, weight and blood pressure. It also includes a listing of the symptoms 30 with adjacent check boxes for recording the diagnostic environment or setting 32 and frequency assessment 34. Advantageously, the joint use portion 14 combines the information which is needed for diagnosis into a single record which may be easily reviewed by both the clinician and the patient. A space 36 is provided to enter examples of the symptoms, including the severity of the impairment. The joint use portion 14 may be completed by the clinician during a structured interview, or it may be completed by the patient. The joint use portion 14 also includes title and pagination indicia 38.
The diagnostic or clinician-use portion 16 shown in FIGS. 3–4 includes diagnostic and assessment information for a selected illness or disorder for use by a clinician. The information in this portion 16 is provided to educate and assist the clinician in reaching a conditional diagnosis and includes instructions 40 for using the interview instrument 12 to implement the tracking system and method 10. Diagnostic criteria 42 are provided for a preselected disorder or illness, including a listing of specific symptoms 30, diagnostic clarifying information 44 for use by the clinician in evaluating the symptoms 30, assessment techniques 46 for use by the clinician in assessing the symptoms 30, impairment and treatment response strategies 48 for assessing changes attributable to treatment. The clinician-use portion 16 also includes space for entry of Notes 50 and a Treatment Plan 52 by the clinician. These spaces are blocked out on the joint use-portion depicted in FIGS. 5 and 6, so that the Notes 50 and Treatment Plan 52 entered into these spaces by the clinician will not be automatically transferred to the pages distributed to the patient.
The diagnostic criteria 42, such as “Symptoms must have persisted for at least 6 months to a degree that is maladaptive and inconsistent with developmental level,” and symptoms 30, such as “often has difficulty sustaining attention in tasks or play activities” may be derived from a diagnostic manual for psychiatric disorders, such as the Diagnostic and Statistical Manual of Mental Disorders(DSM) published by the American Psychiatric Association, or from any other recognized source. In the case of physical illnesses or disorders, the diagnostic criteria 42 may be derived from a medical diagnostic manual such as The International Classification of Diseases (ICD), published by the World Health Organization.
The diagnostic clarifying information 44, includes information specific to the preselected disorder necessary for evaluating the symptoms 30 once they are identified. In the exemplary interview instrument 12 for ADHD, diagnostic clarifying information 44 includes information regarding age of onset of the disorder, number and severity of the symptoms, pervasiveness and persistence of the impairment and persistence of the symptoms 30 designed to aid the clinician making a conditional differential diagnosis. Depending on the preselected disorder, the diagnostic clarifying information 44 may include any other factors recognized to be relevant to evaluation of the symptoms 30.
Although definitive diagnostic tests are available for some disorders, others like ADHD can only be diagnosed following careful assessment of the patient's history and symptoms 30. The interview instrument 12 includes assessment techniques 46 for assisting the clinician in assessing symptoms 30 of the preselected disorder, impairment of the patient attributable to the symptoms 30 and treatment response. Assessment techniques 46 may include interview and history techniques 54 designed to assist the clinician in gathering a complete history necessary to differentiate between situational problems, other disorders and a preselected disorder, such as ADHD. Assessment techniques 46 may also include observation techniques 56 for observing the patient's functioning in a plurality of environments, the family and psychiatric history 58 and medical history 60, which may indicate a likelihood of developing the disorder, identify causal factors, or provide other clues to diagnosis.
Strategies 48 for assessing changes attributable to implementation of a treatment plan include establishing target symptoms 62 and domains of impairment 64 and measuring changes at different drug dosages 66.
Although the term clinician is used herein for consistency, the method 10 and assessment instrument 12 may also be used to good effect by any behavioral or medical practitioner, such as physicians, psychologists, counselors, social workers, speech pathologists, physician's assistants, nurse practitioners, as well as teachers and therapists.
The patient use portion 18 of the instrument 12 is shown in FIG. 7 to include instructions 68 for use of the interview instrument 12. The instructions 68 include directives to learn 70 about the disorder, communicate 72 with the clinician and use the interview instrument 12 to track symptom improvement 74. Depending on the preselected disorder, additional directives may also be included. The patient use portion 18 also includes a patient information section 76 including contact information for organizations that offer resources directed to the disorder and a treatment section 78 that describes the accepted treatment approaches for the disorder. Pharmaceutical information 80 appropriate to the disorder may also be included. The pharmaceutical information 80 may include names of therapeutic agents approved for use in treatment of the disorder and information about dosage, administration, contraindications and warnings. The pharmaceutical information 80 may be accompanied by advertising indicia 81 of one or more selected pharmaceutical companies and the trade names of their therapeutic agents which may be suitable for use in treatment of the disorder. While the pharmaceutical information 80 is preferably printed on the patient-use portion 18 to inform patients of available pharmaceuticals for treating the disorder, this information may also be printed on the clinician-use portion 16.
The follow up report 20 is depicted in FIGS. 8 and 9 to include a plurality of lists of the symptoms 30 of the disorder with adjacent date spaces 82 for entry of the date of each follow-up visit. Adjacent the symptoms 30 are check boxes for No change 84, Improved/still needs attention 86 and Resolved 88. It is foreseen that, for some disorders, a check box indicating regression (not shown) may also be provided. A note space 90 is provided so that the clinician may indicate environmental, time, frequency or any other relevant differences in symptom improvement, e.g. that the symptom 30 is more improved at school than at home or that the symptom 30 is more improved in the morning than later in the day. The Follow-up report 20 includes lines for recording certain patient information such as name 92, parent 94, patient's age 96, grade 98, teacher 100 as well as a note space 102 for entry of any specific problems or concerns of the clinician. Space is also provided for recording physical characteristics such as a height space 104, weight space 106, blood pressure space 108 for recording blood pressure as well as any blood chemistry, such as, for example, serotonin levels, which may be relevant to tracking drug therapy. A medication information space 112 is provided for recording medication information relevant to the disorder, such as whether the medication is continued over weekends and during the summer. A listing of relevant medication side effects with adjacent check boxes 114 is also provided. The follow-up report 20 also includes space 116 for clinician notes/treatment changes, such as adjustment of medication dosage, recommendations for additional therapy such as behavioral therapy and any other treatment recommendations. The follow-up report 20 thus provides a concise record over time of the patient's progress under the treatment plan. The follow-up report 20 is designed primarily for review by the clinician in evaluating the patient's progress. However, it may also be distributed to the patient, so that the patient can review the progress and use this information to better communicate changes in their symptoms 30 to the clinician.
While the exemplary interview instrument 12 addresses two variants of a disorder which frequently occur in combination, Attention Deficit Disorder with or without Hyperactivity, it may also be designed to address other disorders, either singly or in groups of two or more. It may be employed for treatment of patients having some symptoms of any of a number of mental or physical disorders or illnesses, such as anxiety, dementia, disorders of the central nervous system, eating disorders, elimination disorders such as enuresis and encopresis, headaches and migraines, mood disorders such as Bipolar Disorder and Depression, psychoses such as Schizophrenia, sleep disorders, substance abuse, and chronic conditions such as Diabetes and Asthma. Those skilled in the art will appreciate that the system of the present invention can be employed for virtually any conditionally diagnosable mental or physical illness or disorder or combination thereof.
The interview instrument 12 may be implemented as either a printed booklet of tear-sheets or as a computer program generating a video display. FIGS. 1–9 depict the respective pages or screen displays. In booklet form, the exemplary ADHD interview instrument 12 includes two pairs of stacked pages and a third page for the follow-up portion 20. The pages are constructed so that FIGS. 1 and 3 depict respective first and second sides of a first page to be retained by a clinician and FIGS. 2 and 4 depict respective first and second sides of a second page to be retained by the clinician. In similar fashion, FIGS. 5 and 7 cover respective first and second sides of a first page to be retained by a patient and FIGS. 6 and 7 cover respective first and second sides of a second page to be retained by the patient. FIGS. 8 and 9 cover respective first and second sides of a follow-up report 20 to be retained by the clinician as documentation of the progress of the patient. In this manner, the educational material depicted in FIGS. 3 and 4 is imprinted on the reverse sides of the pages to be retained by the clinician and the educational material depicted in FIG. 7 is imprinted on the reverse side of the pages to be distributed to the patient. Where the patient educational material can be fitted onto a single page, as is shown in FIG. 7, then it may be imprinted on the reverse side of each page to be retained by the patient. It is also foreseen that the reverse side of one of the pages could be left blank, or lines for patient notes. Depending upon the length of the joint-use portion 14 and the length of the clinician-use and patient-use educational portions, it may not always be feasible to print the respective clinician and patient education portions on the reverse of the clinician-use 16 or patient-use 18 portions. In such instances, additional pages may be required or the information may be edited for length.
A first Page 1 depicted in FIG. 1 is stacked atop a second Page 1 depicted in FIG. 5. A first page 2 is depicted in FIG. 2 and is stacked atop a second page 2 depicted in FIG. 6. The pages are constructed of so-called “carbonless” paper, so that entries on the first page 1 depicted in FIG. 1 in the setting and frequency check boxes 32 and 34 and notations in the space 36 for description of symptoms and examples are automatically transferred into the corresponding spaces on the second page 1 depicted in FIG. 5. Similarly, entries on the first page 2 depicted in FIG. 2 will be automatically transferred into the corresponding spaces on the second page 2 depicted in FIG. 6.
All of the pages of the interview instrument 12 are of approximately the same size, which may be any suitable size, such as, for example about 81⁄2 inches by about 11 inches, except that the pairs of first and second pages and the follow-up report 20 may be progressively offset from each other by a short distance and imprinted with a title and/or pagination indicia, in the manner of an index. This arrangement serves to facilitate tear-sheet type removal of the copies of pages 1 and 2 by the clinician for distribution to the patient.
The symptoms 30 are arranged on the page fronts with adjacent boxes for indicating the environments described in the diagnostic criteria 42 and assessment techniques 46. The diagnostic criteria 42 and symptoms 30 are elucidated on the reverse side of the pages.
The previously described interview instrument 12, as shown in FIGS. 1–9 is adapted for use in a diagnosis, assessment and symptom tracking system or method 10. FIG. 10 is a flow diagram with blocks representing the following steps of a simplified embodiment of the method 10: providing the clinician with an interview instrument, block 118; conducting an initial patient interview and assessment, block 122; recording symptoms on the interview instrument, block 124; developing a diagnosis and treatment plan and recording the plan on the interview instrument, block 126; implementing the treatment plan, block 128; conducting a follow-up patient interview and assessment, block 133; recording changes in symptoms on the interview instrument, block 136; reviewing the interview instrument to track progress of the patient under the treatment plan, block 138; modifying the treatment plan, block 140; and, alternatively, continuing the treatment plan, block 142 or discontinuing the treatment, block 144. As previously discussed, recording symptoms on the interview instrument, block 124 may be undertaken by the patient, and in such cases precedes conducting an initial patient interview and assessment, block 122.
In more detail, as shown in FIGS. 10 and 11, block 118 corresponds to providing the clinician with an interview instrument specially designed for diagnosis of a selected disorder and previously described in detail in association with reference numeral 12. The interview instrument 12 includes a joint use portion 14 for use by both the clinician and the patient, a diagnostic portion 16 for use by the clinician, a patient-use portion 18 for use by the patient, and a follow-up portion 20 for use by the clinician. While it is useful to organize the interview instrument 12 in this manner, such usage designations are not hard and fast. Any portion of the instrument may be considered to be a joint-use portion 14 where joint use may enhance the interactive nature of the interview and assessment or is likely to improve the treatment outcome.
The diagnostic portion 16 of the instrument 12 includes instructions 40, a list of symptoms 30 and diagnostic and assessment educational information about the disorder for clinician reference. The diagnostic and assessment information includes diagnostic criteria 42, diagnostic clarifying information 44 and assessment techniques 46.
The clinician consults the diagnostic and assessment information contained on the interview instrument, block 120 and conducts the initial interview and assessment, block 122 in accordance with the list of symptoms 30 and the diagnostic and assessment information contained in the interview instrument 12. The clinician next records the symptoms 30, the environment 32 in which they occur and the clinician's assessment of the patient's symptoms on the joint-use portion of the interview instrument, block 124. In some instances, it may be desirable to employ the space 36 for recording the exact words used by the patient to describe the symptoms. It is also foreseen that the patient may participate in this step by recording the symptoms, block 124. It is also foreseen that the instrument 12 may be implemented as a computer program, generating a screen display, which may be accessed and used by either or both of the clinician and the patient to record the symptoms 30. In such instances, the clinician may consult the record of the symptoms 30 prior to conducting the initial patient interview and assessment, block 122.
The clinician next identifies target symptoms for treatment and develops a treatment plan for treatment of the disorder and records the treatment plan on the interview instrument, block 126. The clinician may refer to the recorded symptoms 30, environment 32, frequency 34 and any severity information recorded on the interview instrument 12 in order to identify the target symptoms. The treatment plan may include medical procedures such as surgery, physical or behavioral therapy, administration of therapeutic agents as well as periodic testing, such as blood chemistry, ECG, blood pressure, or any other suitable treatment. The treatment plan is implemented, block 128 and in some instances the interview instrument may be reviewed by a third party, block 130. Third party review may be conducted by private or public insurers, such as Medicare and Medicaid, in order to determine whether and to what extent charges incurred by the patient for the interview and subsequent treatment will be reimbursable, or it may be conducted by state or federal regulatory agencies charged with reviewing quality of patient care.
The clinician distributes both the joint-use 14 and patient-use 18 portions of the instrument 12 to the patient. The patient use portion 18 includes instructions 68, patient educational information about the disorder 76 and a summary of treatment options 78. The patient next reviews at step 132 the patient information and the recorded symptoms 30 on the interview instrument 12. Such patient review enhances communication between the clinician and the patient.
At step 134 the clinician reviews the interview instrument 12 and conducts an interactive follow-up interview of the patient including assessment of the symptoms. Educated by review of the patient information and recorded symptoms on the interview instrument in block 132, the patient is better equipped to identify symptoms of the disorder as they are experienced as well as their environment and frequency. This improves the accuracy of the information garnered during the interview process and the communication of the information to the clinician for recording on the interview instrument 12. It also improves the quality of the patient's choices regarding treatment options and the patient's participation in the treatment itself.
The clinician next records at step 136 any changes in the patient's symptoms on the follow-up report portion 20 of the interview instrument 12. The clinician reviews the interview instrument to 12 track the progress of the patient under the treatment plan at step 138. This review may cause the clinician to determine that the treatment plan is appropriate and should be continued, blocks 140, 142 and 128, that the treatment plan has been accomplished and can be discontinued, blocks 140, 142 and 144, or that the treatment plan should be modified, blocks 140, 128.
In this manner, the interview instrument 12 functions as a dialog tool between the patient and clinician for improving diagnosis and assessment of a disorder or illness across multiple patient care visits. The follow-up report portion 20 of the interview instrument 12 provides documentation of the patient's progress across multiple visits. The follow-up report serves as a tracking tool for third parties who may have an interest in determining whether the patient is making progress under the treatment plan as well as documentation.
It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.
