Abstract

A hospital computerized system (26) includes terminals (24) in all departments (12 and 14) for entering information pertinent to a patient's stay. The initial information entered includes the patient's history (28), admitting physician's physical examination results (3), and physician's orders for tests or hospital services to be performed. The system (26) prints a history and physical report for the patient's chart and highlights abnormal findings and complaints. The system (26) schedules and reschedules all hospital services for the patient on a priority basis, thereby eliminating this responsibility from the nurses and other hospital personnel, and avoids situations where the patient is scheduled to be in two places simultaneously. The system (26) receives and stores all test results and technician's, nurses, and doctor's notes and prints a summarized discharge planning document and a narrative discharge report for the chart, as well as a patient instruction document.

Description

"SYSTEM FOR CENTRALIZED STORAGE OF PATIENT RELATED DATA RECORD INCLUDING MEDICAL NOTES AND TEST RESULTS AND FOR SCHEDULING PATIENT RELATED SERVICES."

This invention relates to a hospital medical record maintenance, generation and scheduling system. and more particularly, to a computerized system located throughout the hospital facility for maintaining and generating required medical records for a hospitalized patient and for scheduling various tests, therapies and other hospital services for that patient.

In the past, record keeping for a hospitalized patient has been a major problem for the proper administration of a hospital and a major administrative drain on the time of the medical staff. A patient 's chart, or file, is typically maintained at the nurse's station, which is in the area of the patient's hospital room. However, documents from various parts of the hospital, such as laboratory reports, physical therapist's reports, doctor's reports and the like are continually generated at locations throughout the hospital, or in other places remote from the hospital, and must be placed in this chart. The need for continual access to the chart places additional work on the hospital support staff, such as the nurses and technicians, who must either travel to the chart area, or te l ep ho ne the nurses station for a report on information contained in the chart. Further, a substantial expenditure of money on the part of the hospital results because of the necessity of employing runners or messengers to physically carry the various reports to the nurses station for inclusion with the chart. These procedures can delay the placing of important documents in the patient's chart for review by physicians and nurses.

Another problem commonly present in most hospital systems is the scheduling of patients for various services performed by the hospital. Some services, such as physical therapy, respiratory therapy, X -r ays and the like may only be able to handle one, or a few, patients at a time. Further, a patient can only be scheduled to be in one place at a time. In order to properly schedule patients, the technicians in the various service organizations and nurses on the patient floor are constantly communicating by telephone to set up appropriate schedules. This takes up valuable time of the hospital personnel, which otherwise could be used for direct patient care. Furthermore, emergency situations often occur in a hospital, resulting in changes to the schedule to permit the emergency tests to be performed, thereby causing normally scheduled non-emergency tests to either be rescheduled or causing the patient to wait for long periods of time at the service area. Again, this takes up additional time αf the hospital support staff which could better be utilized in providing direct patient care.

In addition to the above, there are many other problems which reduce the time that scarce medical staff has available to provided direct patient care. For example, for every patient discharged from a hospital, a discharge summary must be prepared based on the patients hospital stay. Much of the information contained in the discharge summary is contained in the patient's chart and needs to be summarized or abstracted before being placed in the discharge summary. In addition, physicians must dictate the discharge summary relating to the medical conclusions and future care of the patient. This results in additional physician time and inherent delays in the preparation of the discharge summary, since, after being dictated by the physician, it must first be sent to a transcription service firm, which typically is at a location remote from the hospital, and then returned to the hospital for inclusion with the chart before the patient is discharged. A similar problem exists for the history and physical reports, which are generated at the time the patient is admitted.

Most hospitals possess computer systems which are used for much of the administration within the hospital. For example, in most hospitals, computer systems provide the bills for the patients. To generate a bill, substantial data, such as tests and services performed, must be entered into the computer in order for the bill to be generated. Because of the existence of computerized billing utilized in most hospitals, computer terminals are typically positioned throughout the hospital in order to permit the data to be entered at the location that the charge is generated. For example, when laboratory tests are performed, the data is entered into the billing computer directly from the laboratory area so that the cost of the test can be placed on the patient's bill. However, much of the same data may be hand carried to the patient's chart for review by the medical staff.

One could substantially increase the efficiency and reduce the paper work in a modern hospital by more fully utilizing existing computer systems, or by installing supplemental systems, to relieve much of the administrative burdens placed on physicians and support staffs in the hospitals. For example, the maintenance of medical records can be substantially simplified by utilizing computer technology. In addition, the scheduling of patients can be simplified using the computer technology. By combining functions, such as scheduling and chart report generation into single systems, considerable efficiencies and duplications are further eliminated. Since much of the information is already being entered into a computer system for billing purposes, the incremental additional work is minimized. For example, one must now type in the various laboratory tests performed for billing; to additionally type in the test results would not require significant additional effort. The benefit, of course, is that once the test results are entered into the system, anyone with access to a terminal and a password can see the results without physically going to the chart or without calling and disturbing a nurse. Further, as soon as the results are typed into the system, they can be printed at the nurses' station and immediately be placed in the patient's chart. The prior art discloses various computer systems which control portions of a hospital system, but nothing shows the entire integrated system as proposed herein. For example, reference is made to the following United States Patents which show various prior art hospital computerized systems: 3,872,442 in the name of Baker A. Mitchell, Jr. and entitled, "Hospital Data Processing System"; 4,135,241 in the name of Eugene A. Stanis et al and entitled, "Inventory Control, Bed Allocation and Accounting Data Handling System"; 4,315,309 in the name of Robert D. Coli and entitled, "Integrated Medical Test Data Storage and Retrieval System"; 4,491,725 in the name of Lawrence E. Pritchard and entitled, "Medical Insurance Verification and Processing System"; 4,591,974 in the name of Donald H. Dornbush et al and entitled, "Information Recording And Retrieval System"; 4,658,357 in the name of Gary T. Carroll et al and entitled, "Time and Accounting System"; and 4,917,050 in the name of Kenichi Komatsu et al and entitled, "Database System".

In accordance with one aspect of this invention, there is provided a scheduling and reporting system for hospital patients comprising means for entering location data regarding each patient and physician orders for hospital services to be performed for each patient. Further, the system includes means for scheduling the ordered services for each patient and for reporting the schedule information to a common area in the vicinity of each patient's location. The system further includes means for recording and reporting the results of the services administered to each patient to the common area in the vicinity of each patient's location. Finally, the system includes means responsive to the recorded information for generating a discharge summary report for each patient at the conclusion of the hospitalization of such patient.

In accordance with another aspect of this invention, there is provided a method of scheduling patient services and recording patient data for a hospitalized patient comprises the steps of recording and location for each patient and recording physician orders for services to be performed upon each patient. Additionally, the method includes the steps of automatically scheduling the services for each patient, recording the results of the performance of such services and providing the discharge summary record for each patient.

One pr eferr ed embodiment of the subject invention is hereafter described with specific reference being made to the following figure, in which:

Figure 1 shows a block diagram of the improved medical records and scheduling computer system;

Figure 2 illustrates a form a patient may use to provide medical history information for entrance into the computer system of the subject information; and

Figure 3 illustrates a form a physician may use in providing information relating to a physical examination for entrance into the computer system of the subject information.

Referring now to Figure 1, a diagram illustrating the various areas of a hospital which would use the subject invention is shown. These various areas include the admitting area 10, the nurses' stations 12, the various hospital service departments 14 and the medical record's department 1 6 . Within each of these areas 10, 12, 14 and 16, many sub-areas, to be specified hereafter, are included. Typically, each individual area or sub-area of a hospital operates independent of other areas or sub-areas; however, each area or sub-area must constantly communicate with certain other areas or sub-areas to make information generally available. One purpose of the present invention is to facilitate orderly, efficient and rapid communication among the various areas of the hospital and to provide such information with minimal human intervention between the various areas and sub-areas, as necessary. Referring specifically to the admitting area 10. the one portion of the hospital that every patient associates is the admitting office 18. A patient may be admitted to a hospital, through admitting office 18, either through the emergency room 20 or by direct admittance from a doctor's office 22. Normally, some sort of a medical history, physical examination results and physician orders are sent to admitting office 18 by the admitting physician. At the admitting office, a patient's chart is initially set-up and the patient is assigned to a particular bed location in the hospital. Reports of the initial physical examination and patient history, as well as the physician's orders are then placed in the chart. Other documents, such as prior hospital discharge reports may also be placed in the chart.

When using the subject invention, the bed location and other pertinent patient data (name, address, age, sex, etc.) of the patient and the physician admitting orders and history and physical information are entered into terminal 24. This information is transmitted to and stored in main computer 26 in the medical records department 16 and may be accessed by any of the other terminals 24 shown in Figure 1. Of course, the information may be subject to password or other security procedures, which procedures are well known in the art.

The history and physical information may be derived from an emergency room physician's examination of a patient brought into emergency room 20 and may be entered from the terminal 24 in either the admitting office or the emergency room 20. Alternatively, the history and physical information may have been generated earlier during an examination at doctor's office 22 and may be entered from a terminal 24 contained in the doctor's office 22 directly to the admitting office and to computer 26. In such case, the patient may be pre-admitted and go directly to an assigned room without visiting the admitting office 18, or with only a short visit to the admitting office 18. One time saving technique for entering the history and physical information utilizes a program in which all normal components of a patient's history and physical examination are pre-programmed. Such a program permits the physician to merely recite abnormal findings by dictating or checking a form for later data entry of the abnormalities. A form 28, of a type which may be completed by the patient, with or without assistance from a nurse or other member of the physician's staff, is shown in Figure 2. A form 30, of a type which may be used by the physician for providing the information results of a physical examination, is shown in Figure 3. Alternatively, the physician may use form 30, shown in Figure 3, as a guide in dictating a physical examination report and need only dictate the abnormal findings. As seen in both Figures 2 and 3, both forms 28 and 30 list many possible problems which could be associated with a particular patient. To use the forms 28 and 30, only the abnormal blocks need be checked. When the data is entered into the terminal 24, the screen prompting the data entry operator will be organized similar to the various sections of the forms 28 and 30 and the information on the forms 28 and 30 is thereby easily entered through terminal 24 into computer 26 of the system shown in Figure 1. An example of the entire forms 28 and 30 is shown in Appendix I and Appendix II hereto, respectively.

As seen in Figure 2, the patient history portion of the required information is initially provided by the patient filling in the lines or checking the appropriate blocks of form 28. The blocks are organized by the various medical systems of the body. As seen from Figure 3, the physical examination form 30, as well as the program of computer 26, segregate each various part of the body, so that a physician may indicating by a checkmark or by dictation, that a particular part of the body has no medical problems. This is indicated by the WNL (within normal limits) block. Alternatively, where particular medical problems are found during the physical examination, that prob lent is manifested by either circling a system, followed by a comment to be filled in the blank on the form. Alternatively, the physician may dictate the abnormal results of the examination by simply referring to form 30 as a guide. Form 30 further includes a block labeled "DEFERRED" which may be checked if no examination of that particular body system was made, or if a referral to another physician is necessary.

From the information provided using the forms 28 and 30 in Figures 2 and 3, a h i story and physical report meeting the requirements of the Joint Commission For Accreditation Of Healthcare Organizations can be prepared by computer 26, setting forth the entire physical condition of the patient including both normals and abnormalities. The output device, such as the printer or screen monitor, or both, is programmed to print or display the abnormalities in bold, underlined or italics text for easy scanning by other physicians and medical service personnel. The history and physical report includes both the patient's past medical history , wh i ch is typ ica l l y generated by the pat ient , and the results of a physical examination. In either case, it is necessary to only enter the abnormalities because the normals are pre-programmed within the system.

Where a patient has completed the General section 32 of form 28 shown in Figure 2 by checking the Fever, Chills and Night Sweats blocks under the General system block 32, the history and physical report may include a clause under the heading Clinical History, as follows: "General: The patient complains of fever, chills and night sweats. The patient reports no weakness, fatigue nor fainting." The report may contain the following sentence under the heading Physical Examination, where the physician has checked, or dictated, for the General block 34 as seen in Figure 3, that the patient is a 50 year old White Female, that is malnourished. "General: The general examination reveals this 50 year old white female is well developed, is malnourished, alert, does not appear acutely ill and is cooperative." It should be noted that in the narrative transcript report, the portions checked or completed are printed in a bold print and the items left blank are printed in normal print. This makes a review of the report easier for those wishing to scan for only medical problems.

Once the patient has been admitted through admitting office 18 and the chart has been prepared, the physician's order document and the history and physical examination report are inserted into the chart. Then, both the patient and chart are transferred to the assigned bed location. If the patient had previously been hospitalized and the subject system had been in use, the past discharge summary could also be retrieved from long term storage device 36 and reprinted for inclusion in the chart. This will be described in more detail hereafter.

Every bed location in a hospital is in a defined type of patient areas, typically a floor, wing, etc. For example, typical floors, wings, or patient areas of a hospital include the ICU/CCU area for critically ill patients, the medical area for patients undergoing diagnostic testing or recovering from illnesses, the surgical area for preoperative and post-operative patients, the pediatrics area for ch i l dren and the obstetrics area for obstetric's patients. Of course, different hospitals may have different or additional patient areas. Within each of the various patient areas of a hospital, a central nurses' station is typically present and such nurses' stations are shown in Figure 1 in nurses' station block 12. Located at each of the nurses' stations 12 is a terminal 24, which includes a keyboard, screen display and printer device.

When the patient is transferred to the bed in one of the nurses' station 12 areas of the hospital, the chart is physically stored at the central nurses station. New documents are to be placed into the chart as they are received on the printer associated with terminal 24 at the particular nurses' station. In addition, nurse's initial assessments, patient readings, such as blood pressure, tem perature, fluid intake and output etc., and other similar information may be entered and printed through the nurse's station terminal 24. This permits the information to be stored in the central computer 26 and exist in the patient's chart. In addition, the information that is entered through one of the terminals 24 is stored in central computer 26, as well as being printed on the printer at the nurses' station for inclusion in the paper chart. As will be discussed hereafter, the information printed on the nurses' station printer may also be entered at various other locations in the hospital.

At the time the physician's orders were entered in admitting office 10, the information was stored in central computer 26. Typical of the physician's orders would be the performance of certain tests, such as laboratory tests, X-rays, neurology tests and the like, and the provision of certain therapies for the patient, such as physical therapy, respiratory therapy and the like. Additionally, the physician may order certain medication for the patient from the hospital pharmacy or special diets for the patient from the hospital dietary department. The information entered from the physician order is stored in computer 26 and transferred to the appropriate hospital service departments 14, where it is printed or displayed on the terminal 24 at such department. As an example, the various departments in a hospital may be the Neurological (NEURO) department, the Cardio-Pulmonary (CARDIO PULM.) department, the pharmacy (PHARM) department, the Laboratory (LAB) department, the Radiology (X-RAY) department, the Respiratory Therapy (RESP. THERAPY) department, the Physical Therapy (PHYS. THERAPY) department, and the kitchen (DIETARY) department.

For the hospital departments 14 giving tests or providing therapy services, it is not sufficient to merely advise each of the departments 14 of the fact a test is to be performed or that a certain therapy is to be given. Many tests or therapies are available to one, or a limited number of patients at a time. Further, a patient can only be at one place at any given time. For example, certain X-ray tests are only available for one patient at a time and it is necessary to schedule the patients to fully utilize the X-ray equipment, while at the same time not delaying for unacceptably long periods the time required to perform the X-ray. Thus, it is desirable that computer 26 schedule the time each test and therapy is to occur for the entire hospital.

At the time the physician order is entered through terminal 24 at the admitting office 18, the tests requested may be designated in a priority manner. For example, the physician may determine that the test should be performed STAT, indicating immediately, ASAP (as soon as possible), indicating that same day, or Routine, indicating during the next available time slot. Where a high priority test is ordered, computer 26 may have to reschedule previously scheduled tests. This is easily accomplished by a conventional Bchpduling program and by printing or displaying the rescheduled times at both the department terminal 24 and the nurses' station terminal 24. As the tests and therapies are completed, the schedule may be revised to minimize patient waiting where the department is behind schedule, or to minimize technician waiting if a department is ahead of schedule.

After tests are completed, the test result information is transmitted by the testing department to computer 26 and computer 26 causes the information to be printed on the printers at the appropriate nurses's station 12 closest to the patient's location. The test results may include raw test results, such as blood test results, or may include interpretations made by a physician, such as in the case of an X-ray or EKG reading. Again appropriate forms to be completed, or to serve as dictation guides, similar to forms 28 and 30 in Figures 2 and 3, may be used by the phy- sicians interpreting the test results. Once the test results are printed at the nurses' station, the printed paper is placed in the patient's chart. Since the test results or interpretations are also stored in central computer 26, the attending physician, or a consulting physician, is able to review the results from their own terminal 24 without having to go to the hospital. When the test results are entered, computer 26 further causes appropriate billing for the tests performed. By using the same system that schedules and reports test results to derive billing information, duplicate billing and non-billing situations can be reduced.

In addition to utilizing the nurses station terminals 24 for displaying the scheduled information, the nurses initial histories and daily patient information, such as blood pressure, heart rate, temperature, respiratory rate and fluid intake and output can be recorded and stored in computer 26. Each of the patient information entries may be reported back to nurses station 24 or, as will be explained hereafter, printed in a discharge summary in the form of graphs or in an abstracted form as determined by the program for computer 26. In addition, the information may be printed at the nurses' station terminals 24 for inclusion in the patient's paper chart for referral by physicians or other medical personnel. Since the same information will be stored by computer 26, it may also be reviewed by a physician having access to a terminal in his office without having to come to the hospital.

Each of the various hospital service departments receive instructions and/or provide results or comments to terminals 24 associated in their area . Further, billing information is normally taken from the provision of the results or comments indicating that the ordered service has been completed. For some services, only test results are reported. For other services, comments of a therapist or physician are reported. In all instances, the reported information is stored in the memory of computer 26 and printed at the nurses' station for inclusion in the patient's chart. In addition, additional physician generated information may be entered from a terminal 24 and stored in computer 26, particularly where new patient ailments or a change in treatment occur. Also, medical findings may be entered and stored in computer 26.

The above described sequence of scheduling and data reporting continues for the duration of the patient's stay in the hospital. When the patient is to be discharged from the hospital, a discharge summary report must be prepared, which meets the requirements of the Joint Commission For Accreditation Of Healthcare Organizations. Portions of the discharge summary report include items dictated by the physician or entered by completing the Discharge Planning form attached hereto as Append i x I I I . I n add i t ion , o ther por t i ons include a summary, or abstracting, of the test result data, the treatments, new complaints and the like.

In preparing the Discharge Summary report, computer

26 prepares the Discharge Planning document (Appendix III) for completion by the physician. The Discharge Planning document is based upon the initial patient complaints and abnormal findings entered at the admitting office 18, as supplemented by additional patient ailments and abnormal physical findings entered during the patient's stay in the hospital. The Discharge Planning document is generally requested by the attending physician the day prior to anticipated discharge and is completed so that the proper discharge documents may be prepared in time for the patient's discharge the next morning. The Discharge Planning document is in a form which first lists each diagnoses listed on the Physical Examination Report (Figure 3 and Appendix II) entered as part of the admitting procedure, as supplemented by additional diagnoses made during the hospital stay and entered as physician's comments. Next, a section for a discharge diagnoses is provided for completion by the physician.

Thereafter, the Discharge Planning document lists the various patient complaints and includes an area for the physician completing the Discharge Planning document to check whether the complaint was stable, improved spontane αusly, resolved spontaneously, improved with treatment or resolved with treatment. In addition, a block labeled "Other", together with an associated space, is provided. For comp l a i nts wh ich changed , or were reso l ved , w i th treatment , a space is provided for physician's comments. Next a similar section is provided based .upon the physical examination abnormal findings entered originally, or as supplemented during the haspitalization.

Finally, a summary and abstraction of the various department 14 reports is provided. These may include the admission, or first, reading, discharge, or last, reading and the hospital course reading. The hospital course reading is a reading between admission and discharge and may typically be the highest, or most abnormal reading. If all interim readings were normal, the hospital course reading may be left blank. Of course, some services may not have been utilized during the hospitalization and will be blank, or there may only be one or two readings. In addition, a place is provided for the physician completing the Discharge Planning document to indicate that a particular section is non-contributory and should be left out of the discharge summary report.

The Discharge Planning document concludes with a prognosis section, a discharge instruction section and a disposition section, all of which are to be completed by the attending physician. The disposition section is used to indicate whether the patient is to be allowed to go home, to a nursing home, a rehab center, or the like. If the patient is to go to a nursing home, rehab center or the like, a social service module of the program of computer 18 includes a database for determining whether such a facility is available for that patient. If not, the final Discharge Report may be delayed. Alternatively, the disposition may indicate that the patient is referred to another physician, generally a specialist for the ailment determined during hospitalization. Once the Discharge Planning Document is completed by the physician, a Discharge Summary document is prepared in narrative form, with the abnormal results highlighted, such as being printed in bold. In addition, Discharge Instructions in layman's terms are prepared and handed to the patient upon discharge. Of course, the patient's final bill is provided at the same time.

In case the patient ever returns to the hospital, it would be advantageous to be able to recall the significant events of the prior hospital stay. In order to provide this information, the discharge summary, and other pertinent information may be stored in a long term storage device 36, such as a laser disk memory. In such a system, multiple disks may be necessary and will be typically organized based upon a period of time. Each patient entry may be cataloged by patient name and/or social security number, for example, and a master database, sortable by patient n ame and/or social security number, should be maintained for the multiple disks, so that the next time the patient enters the hospital, the pertinent information may be retrieved, reprinted and placed in the patient's chart. At most, one disk per hospitalization will have to be loaded into storage device 36 and the patient's past hospitalization history can be quickly retrieved. In other words, it is no longer necessary to go to the warehouse and retrieve the paper chart from storage to see the pertinent events of the prior hospital stay.

From the above description, it is seen that the same information is used for many different aspects of the required records management requirements for patient care. Further, the computer system is programmed to abstract certain information and ignore other information based upon the normality or abnormality of the results, thereby making the task of the medical personnel easier and freeing time for patient care. While the subject computerized hospital system has been described as a series of remote terminals 24 communicating w i th a centra l computer 26 , the system may be set up as one or more local area networks, or a combination of such systems.
