A web-based rapid prototyping and clinical conversational system that complements electronic patient record system.

Even the most extensive hospital information system cannot support all the complex and ever-changing demands associated with a clinical database, such as providing department or personal data forms, and rating scales. Well-designed clinical dialogue programs may facilitate direct interaction of patients with their medical records. Incorporation of extensive and loosely structured clinical data into an existing medical record system is an essential step towards a comprehensive clinical information system, and can best be achieved when the practitioner and the patient directly enter the contents. We have developed a rapid prototyping and clinical conversational system that complements the electronic medical record system, with its generic data structure and standard communication interfaces based on Web technology. We believe our approach can enhance collaboration between consumer-oriented and provider-oriented information systems.

The CCC system in two teaching hospitals: a progress report.

Computing systems developed by the Center for Clinical Computing (CCC) have been in operation in Beth Israel and Brigham and Women's hospitals for over 10 years. Designed to be of direct benefit to doctors, nurses, and other clinicians in the care of their patients, the CCC systems give the results of diagnostic studies immediately upon request; offer access to the medical literature: give advice, consultation, alerts, and reminders; assist in the day-to-day practice to medicine, and participate directly in the education of medical students and house officers. The CCC systems are extensively used, even by physicians who are under no obligation to use them. Studies have shown that the systems are well received and that they help clinicians improve the quality of patient care. In addition, the CCC systems have had a beneficial impact on the finances of the two hospitals, and they have cost less than what many hospitals spend for financial computing alone.

Guidelines for management of HIV infection with computer-based patient's record.

Computers are steadily being incorporated in clinical practice. We conducted a nonrandomised, controlled, prospective trial of electronic messages designed to enhance adherence to clinical practice guidelines. We studied 126 physicians and nurse practitioners who used electronic medical records when caring for 349 patients with HIV infection in a primary care practice. We analysed the response times of clinicians to the situations that triggered alerts and reminders, the number of ambulatory visits, and hospitalisation. The median response times to 303 alerts in the intervention group and 388 alerts in the control group were 11 and 52 days (p < 0.0001), respectively. The median response time to 432 reminders in the intervention group was 114 days and that for 360 reminders in the control group was over 500 days (p < 0.0001). There was no effect on visits to the primary care practice. There was, however, a significant increase in the rate of visits outside the primary care practice (p = 0.02), which is explained by the increased frequency of visits to ophthalmologists. There were no differences in admission rates (p = 0.47), in admissions for pneumocystosis (p = 0.09), in visits to the emergency ward (p = 0.24), or in survival (p = 0.19). We conclude that the electronic medical record was effective in helping clinicians adhere to practice guidelines.

Patient entries in the electronic medical record: an interactive interview used in primary care.

We describe the development, implementation, and use of a computer-administered patient interview, the Health History Interview, by over 300 new patients in a primary care practice at Boston's Beth Israel Hospital. The interview has been well accepted by patients and rated positively by providers. It electronically captures clinical information directly from patients for use during their initial encounter with a provider. It facilitates aggregate analysis of clinical data for quality improvement efforts, such as aiming preventive medicine interventions at identified problem areas within the clinic. Expectations management has been an important task throughout the project. Increasing use of the interview beyond the 30-40% of new patients who have taken it will require greater communication with patients, greater convenience to patients and providers, and more evidence of the clinical, administrative, and research benefits of the technique. Most important, full implementation will require fundamental changes in physician practice habits and patterns of communication between patients and the health care system, as well as clearly demonstrated cost-benefit improvements through the use of these tools.

Effect of computer-based alerts on the treatment and outcomes of hospitalized patients.

BACKGROUND: Hospital computing systems play an important part in the communication of clinical information to physicians. We sought to determine whether computer-based alerts for hospitalized patients can affect physicians' behavior and improve patients' outcomes. METHODS: We performed a prospective time-series study to determine whether computerized alerts to physicians about rising creatinine levels in hospitalized patients receiving nephrotoxic or renally excreted medications led to more rapid adjustment or discontinuation of those medications, and to determine whether such alerts protected renal function. RESULTS: Laboratory data were observed for 20,228 hospitalizations, with documentation of 1573 events (instances of rising creatinine levels during treatment with a nephrotoxic or renally excreted drug). During the intervention period, doses were adjusted or medications discontinued an average of 21.6 hours sooner after such an event (P < .0001). For patients receiving nephrotoxic medications during the intervention period, the relative risk of serious renal impairment was 0.45 (95% confidence interval, 0.22 to 0.94) as compared with the control period, and the mean serum creatinine level was 14.1 mumol/L (0.16 mg/dL) lower on day 3 (P < .01) and 25.6 mumol/L (0.29 mg/dL) lower on day 7 (P < .05) after an event. Forty-four percent of physicians who responded to a questionnaire said that the alerts had been helpful in the care of their patients, whereas 28% found them annoying. Sixty-five percent wished to continue receiving alerts. CONCLUSIONS: Computer-based alerts regarding patients with rising creatinine levels affect physician behavior, prevent serious renal impairment, preserve renal function, and are accepted by clinicians.

Be well!: a computer-based health care interview for hospital personnel.

We developed a computer-based health care interview for employees at an urban teaching hospital. The interview is part of the hospital-wide, integrated Center for Clinical Computing (CCC) system at the Beth Israel Hospital in Boston, and is available on 1500 terminals located throughout the hospital. The program emphasizes medical problems and patterns of living for which behavioral change is considered desirable. Conducted in private and with protection of confidentiality, the interview offers information about people and facilities available to help members of the hospital community seek better health. Between May 15, 1990, and May 14, 1992, a total of 1281 people completed the interview, and 84% indicated an interest in one or more of the health-related programs offered by the hospital. That these are difficult times in America was illustrated by the unhappiness reported by 43% of the participants, including 5% who indicated that life sometimes seemed not worth living. We hope they availed themselves of the opportunity offered by the interview to obtain help for their problems, and that other hospitals will do what Beth Israel Hospital is doing to promote well-being among its employees.

An electronic medical record that helps care for patients with HIV infection.

We have built a clinical workstation to help doctors and nurses care for patients with HIV infection. This knowledge-based medical record system provides medication alerts, reminders about primary care, and on-line information to support the care of patients with HIV infection. We are conducting a controlled clinical trial of this computer system in a single practice setting, which consists of 18 staff physicians, 13 nurses, and 113 residents, who cooperatively practice in four teams. Two teams of physicians are assigned to an intervention group and two teams to a control group. This paper reports preliminary results from the first year of study, January 15, 1992, through January 14, 1993. During this period 274 patients with HIV infection were followed by the general medical practice--130 in a control group and 144 in an intervention group. Physicians in the intervention group more rapidly and more completely followed primary care guidelines than did physicians in the control group. Patients in the intervention group had 2476 ambulatory or emergency visits (17.2 visits per patient) compared with 1882 visits (14.5 visits per patient) for the control patients (p < 0.01). There were 101 hospitalizations for 51 patients in the intervention group (an admission rate of 0.7) compared with 104 admissions for 54 patients in the control group (an admission rate of 0.8) (p = NS). There were 8 deaths in the intervention group (5.6%) compared with 13 (10%) in the control group (p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Use of electronic mail in a teaching hospital.

Electronic mail has been in use for almost 20 years at Boston's Beth Israel Hospital and is an integral part of the clinical information system. Through a study of usage patterns during a one-week period, we found that 1247 persons sent 7482 messages to 1302 different recipients. Each category of user (attending physician, house officer, nurse, etc.) sent the most e-mail to others of the same user category. Through an electronically administered questionnaire, we found that self-reported usage patterns had a high correlation (r = 0.6) with measured use. Sixty-six percent of respondents used e-mail daily or weekly, and 58% used it for issues of patient care; nearly all users found this useful for communicating about patient care issues. Ninety percent of respondents felt e-mail made their lives easier and 61% felt it had a humanizing influence on their lives. We conclude that the e-mail system is well-utilized by clinical personnel and felt to be useful in both patient care and nonpatient care situations.

Computer-based interview for screening blood donors for risk of HIV transmission.

OBJECTIVE: To test the ability of a computer-based interview to detect factors related to the risk of the human immunodeficiency virus (HIV) among potential blood donors and to determine donor reactions to the use of the interview. DESIGN: A comparison of the rate of detection of HIV-related factors elicited by a computer interview with that obtained by standard American Red Cross procedures for assessment of donor suitability, including a randomized crossover trial in which the order of the two methods was reversed. Information obtained by the computer was not available to influence the use of blood components for transfusion. SETTING: The computer interview was administered to donors at an American Red Cross blood donor center and at a mobile blood drive at a hospital. SUBJECTS: Consecutive sample of 294 male and female blood donors 18 to 75 years of age. MAIN OUTCOME MEASURES: Subjects' responses to the computer-based interview as well as responses to the standard Red Cross written questionnaires and face-to-face interviews were used for donor assessment. RESULTS: The interview took an average of 8 minutes to complete. From among 272 donors who provided complete data, the computer identified 12 donors who reported either behaviors associated with a risk of HIV acquisition or symptoms compatible with the acquired immunodeficiency syndrome; none of these donors had been so identified either by routine written questionnaires or by face-to-face interviews used to screen potential blood donors. Only one of the 12 identified donors used the confidential unit exclusion procedure to prevent use of his donated unit. The rate of elicitation of HIV-related factors by the computer interview was 12 (4.4%) of 272 (95% confidence interval [CI], 2.3% to 7.6%), compared with two (0.13%) of 1536 (95% confidence upper bound, 0.28%) using the standard Red Cross procedure (P less than .0001). Tests for antibodies to HIV were negative in blood samples from all of the 272 subjects studied. The subjects enjoyed the computer interview and judged it to be more private than the standard donor assessment method. They also predicted that donors would be more honest with the computer interview than with a human interviewer. CONCLUSIONS: Computer-based screening elicits more HIV-related factors in the health histories of blood donors than do the standard questionnaire and interviewing methods currently in use. Computer-based screening is also acceptable to blood donors.

The effect of computer-based reminders on the management of hospitalized patients with worsening renal function.

We performed a prospective time-series study to determine whether computerized reminders to physicians about rising creatinine levels in hospitalized patients receiving nephrotoxic and renally excreted medications led to more rapid adjustment or discontinuation of those medications, and to evaluate physician acceptance of computerized reminders. Laboratory data were followed on 10,076 patients over 13,703 admissions generating 1104 events of rising creatinine levels during treatment with nephrotoxic or renally excreted medications. During the intervention period, medications were adjusted or discontinued an average of 21.1 hours sooner (p less than 0.0001) after such an event occurred when compared with the control period. This effect of the reminders was strongest for patients receiving renally excreted and mildly nephrotoxic medications. Of physicians who responded to a computerized survey, 53% said that the reminders had been helpful in the care of their patients, while 31% felt that the reminders were annoying. Seventy-three percent wished to continue receiving computerized reminders. We conclude that computerized reminders are well-accepted in our hospital and have a strong effect on physician behavior.

ClinQuery: a system for online searching of data in a teaching hospital.

We designed a user-friendly computer program that permits physicians to search the clinical database of Boston's Beth Israel Hospital by clinical and demographic descriptors. For example, the user can identify all admissions in which diabetic ketoacidosis was diagnosed, the serum bicarbonate level was under 12 mmol/L, and the length of stay exceeded 7 days. Once particular admissions are identified, all data stored in the computerized record can be displayed. Authorized persons can also request the patient's complete medical record for further study. Over a 30-month period, 530 doctors, nurses, medical students, and administrators used the program to search the hospital's clinical database 1786 times. They displayed detailed information on 30,851 patients and requested the complete medical record 5319 times. In 1389 of the 1786 searches completed, the searcher responded to a computer-based questionnaire about motivation for the search. Responses indicated that 32% of the searches were for clinical research, 17% for patient care, 17% for teaching and education, 11% for hospital administration, and 12% for general exploration. In 58% of the searches, respondents indicated definite or probable success in finding the desired information. We conclude that physicians and allied personnel will repeatedly obtain, view, and analyze aggregate clinical information if they are provided with appropriate tools. We believe that such access to clinical information is an important resource for patient care, teaching, and clinical research.

Self-service computerized bibliographic retrieval: a comparison of Colleague and PaperChase, programs that search the MEDLINE data base.

Colleague and PaperChase are the two most widely used computer systems designed specifically for clinicians and scientists who wish to search the National Library of Medicine's MEDLINE data base of references to the biomedical literature. The present study compares the performance of these two systems. Two matched groups of second-year medical students each received 3 hr of instruction, one group in Colleague, the other in PaperChase. Each student then attempted 10 test searches. The next day the groups were reversed, and each student attempted 5 additional searches. During 3 1/2 hr allocated for searching, users of Colleague attempted 64 test searches and retrieved 326 target references; users of PaperChase attempted 78 searches and retrieved 496. Users of Colleague took a mean of 2.2 min and spent a mean of $1.20 to find each target reference; users of PaperChase took 1.6 min and spent $0.92. We conclude that after limited training, medical students find more references faster and at lower cost with PaperChase than with Colleague.

Relation between age, education, and time to respond to questions in a computer-based medical interview.

The time required for 458 women volunteers to respond to questions in a computer-based medical interview was related both to their age and to their formal education. When the analysis was restricted to the 220 women with a college degree, older women responded more slowly than their younger counterparts, and when the analysis was restricted to the 265 women between 18 and 30 years of age, women with less formal education took longer to respond. By contrast, the time required for the volunteers to record their responses was related only to age.
