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.

We developed a computer-administered health screening interview for the employees of an urban teaching hospital. The interview is part of the integrated Center for Clinical Computing (CCC) clinical information system used throughout the hospital, and is available on any of 2000 terminals. Conducted in private and with protection of confidentiality, the interview seeks information on medical problems and patterns of living for which behavioral change is considered desirable. In a four-year period ending in May 1994, 1937 employees completed the interview. The results showed that stress and unhappiness were common: 57% of the employees reported high levels of stress, and 42% reported feeling sad, discouraged, or hopeless in the previous month; 6% indicated that life sometimes did not seem worth living. Eighty-six percent of the employees expressed an interest in the health-related programs offered by the hospital: 72% were interested in the fitness center, and 37% in the stress-reduction program. We conclude that if interactive health-promotion programs are easily available, they will be used and appreciated in the work place. The programs can be written to reveal the employees' health concerns and stimulate their interest in promoting their own health.

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 computer, we compared the rate of detection of HIV-related factors elicited by the computer interview with the rate elicited by standard American Red Cross procedures (written questionnaires and face-to-face interviews) for assessment of donor suitability. The study was performed at a Red Cross blood donor center and a hospital. A consecutive sample of 294 male and female blood donors 18 to 75 years of age participated in a randomized crossover trial in which the order of the two methods was reversed. Among 272 prospective donors who provided complete data, the computer identified 12 who reported either behavior associated with a risk of acquiring HIV or symptoms compatible with AIDS. None of these 12 was so identified by face-to-face interviews or written questionnaires. Only one used the confidential unit exclusion procedure to prevent use of his donated blood. Tests for antibody to HIV were negative in blood from all 272 subjects. The subjects enjoyed the computer interview and judged it to be more private than the standard method for donor assessment.

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.

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.

Although computers are now commonly used for financial purposes in hospitals and physicians' offices, most physicians do not routinely use them in patient care. And in hospitals where laboratory data are provided on computer terminals, the displays are often difficult to use and programs that offer assistance in interpreting the data are usually unavailable. We have developed decision support programs that are widely used with the clinical computing system at our hospital. This paper describes the programs and how the clinicians use them.

Schools of talking therapy generally consider the doctor-patient relationship to be essential to the therapeutic process. Yet studies reveal that the presence of a therapist can sometimes inhibit frank disclosure and that patients will speak alone, in the absence of a therapist, about matters of importance to them. We have programmed a computer interview to facilitate soliloquy and have studied its effectiveness. Encouraged by the computer, subjects talked into a microphone first about anxiety-provoking circumstances and then about relaxation. Both mean heart rate and State anxiety scores fell significantly between the beginning and the end of the interview.

The authors briefly review some problems encountered in collecting and interpreting dietary data and in analyzing them by hand and by computer methods. The use of computers, meant to speed processing, has often delayed processing or merely replaced computation time with coding time. The authors describe a simplified nutrient data base and an interactive retrieval method, Quick Input of Food, which has been developed for direct use by nutritionists with their clients.

A computerized supplement to a hospital's drug information newsletter, called Drugman, is described. The pharmacy department of a 452-bed teaching hospital developed Drugman. The program uses the "Converse" software, which was developed by the hospital's computer medicine department. The program provides information on new drugs recently added to the formulary and updated information on current formulary drugs. It also provides information on investigational drugs. A staff pharmacist is responsible for coordinating the writing and review of each new-drug monograph in the system, as well as the computer entry and up-dating of existing monographs. The program is available to all medical, nursing, and pharmacy personnel via computer terminals located on each nursing unit and in the pharmacy department. Survey questions at the end of the program elicit user response to the program and suggestions for additions or changes. In the initial 14-month period, the general response to Drugman has been favorable. Drugman represents a new method of disseminating drug information via computer in an individual hospital. The program complements traditional drug information sources and has been received positively in our hospital.
