The effect of educational preparation on physician performance with a sexually transmitted disease-simulated patient.

BACKGROUND: Simulated patients are used with increased frequency for medical students and residents, but have not been used very often with practicing physicians. We hypothesized that educational materials could improve primary care physicians sexual practices history taking and counseling as assessed by a simulated patient in the physician's office. METHODS: Simulated patient (SP) visits were made to 232 (75% of eligible) primary care physicians. The patient simulated was a sexually active young woman with vaginitis and sexually transmitted disease/human immunodeficiency virus risk behaviors. In advance of the visit, physicians were provided educational materials (monograph, pamphlet, and audiotape) developed for the study, including a risk assessment questionnaire that could be used with patients. RESULTS: Most physicians randomly allocated to the intervention participated. Twenty-one percent of physicians refused to schedule an SP visit. Physicians who received an SP rated the experience highly. Physicians who prepared for the visit with the educational materials performed significantly better than those who did not. About two thirds of physicians reviewed the materials, many for the second time, after the SP visit. Physicians who used the study risk assessment questionnaire performed better. Many physicians (24.9% to 39.8%) did not meet each of the four goals for the visit, as assessed subjectively by the SP. Physician performance was better for measures of general patient interaction than for measures of sexual practices history taking and counseling techniques. CONCLUSION: The SP visit was acceptable to most physicians practicing in a community and was evaluated by them as an appealing and an effective educational experience. The SP, however, has limited feasibility because of cost. The SP led to review of materials by nearly all physicians either before or after the visit. Physicians who prepared before the visit performed better on every dimension, eliciting more information, displaying better patient interaction skills, and meeting more of the educational goals. Even with educational preparation, however, many physicians were not perceived as being effective counselors.

Patient simulators in teaching patient education skills to family practice residents.

The University of Texas Medical Branch Family Medicine Residency includes in its curriculum the use of interviews with simulated patients for the teaching of patient education skills. Success with simulated cases requires careful programming of the stimulator, realistic situations, and objective evaluation and feedback for the residents. This paper describes the "patient education guidelines" which we used in programming a simulated patient, as well as specific objectives for the content of the residents' interviews and a rating form for evaluating the educational process used by the residents. The interviews with a simulated patient were video taped for review by faculty and residents, using the content objectives and the rating form as aids in the feedback session.

Real problems: a layered approach to constructing a patient simulation.

We propose and have implemented a program, called "Real Problems", for the authoring of simulated patient encounters. This program uses a layered database approach to separate the unchanging sections of the program from the more patient-specific sections, so as to increase the speed of authoring. The user's interest is maintained through the use of graphics, sound and extensive feedback.

Case specificity of performance with simulated patients.

In the part one examination for membership of the Royal New Zealand College of General Practitioners (MRNZCGP) patient simulations are used to assess candidates' communication and management skills. In the 1989 examination two different scoring proformas were used to determine if the scoring method contributed significantly to the degree of case specificity that has been observed. The results of this study demonstrate significant differences in performance between cases, while interexaminer rating of performance within cases showed no significant difference. Such results indicate that the between cases differences in measured performance are indicative of real differences and are not reducible by manipulation of the scoring method.

A computer management system for patient simulations.

A series of interactive videodisc patient simulations is being used to teach clinical problem-solving skills, including diagnosis and management, to dental students. This series is called Oral Disease Simulations for Diagnosis and Management (ODSDM). A computer management system has been developed in response to the following needs. First, the sequence in which students perform simulations is critical. Second, maintaining records of completed simulations and student performance on each simulation is a time-consuming task for faculty. Third, the simulations require ongoing evaluation to ensure high quality instruction. The primary objective of the management system is to ensure that each student masters diagnosis. Mastery must be obtained at a specific level before advancing to the next level. The management system does this by individualizing the sequence of the simulations to adapt to the needs of each student. The management system generates reports which provide information about students or the simulations. Student reports contain demographic and performance information. System reports include information about individual patient simulations and act as a quality control mechanism for the simulations.

A field test of the TIME patient simulation model.

The Technological Innovations in Medical Education (TIME) Project has created an interactive videodisc patient-simulation model that provides faculty with a new method for patient-centered teaching in the medical school classroom. The TIME model is designed to be controlled by a professor in the classroom setting, and incorporates voice recognition technology and video dramatization to create a believable patient encounter. Under the auspices of the Lister Hill National Center for Biomedical Communications, National Library of Medicine, where the Project originated in 1983, three medical schools participated in a field test of this "high-tech" model. Six faculty members made ten classroom presentations of two TIME simulations to 306 second-year medical students. The principal finding was that, in a group setting, a large majority of the students at all three schools became individually committed to the care and management of the simulated patient. They acted as if the patient's problems were real and left the session feeling as though they had interacted with an actual person. Therefore, in terms of simulating a real patient, the TIME patient-simulation model was validated, providing the basis for the development of new patient-centered methods to teach and test medical students in the classroom setting. The Project has been at the Georgetown University School of Medicine, where the model is being introduced into the existing curriculum, since 1988. It is currently being used as a part of the final examination for second-year students and in discussion-group settings for fourth-year students in the internal medicine clerkship. A field test is also under way using the TIME model to assess the clinical performance of third-year students.

Computer-based patient simulations: hospital pharmacists' performance and opinions.

The performance of pharmacists in using an interactive computer-based patient simulation program and their attitudes toward the simulations are reported. The Institutional Patient Medication Simulation program is designed to enhance and evaluate the medication problem-solving skills of pharmacists. Each simulation consists of patient data-gathering, case question, and therapy decision modules with initial assessment and monitoring nodes. Five simulations were tested: gout, urinary-tract infection, congestive heart failure, antimicrobial prophylaxis in surgery, and hypertension. Pharmacists from nine hospitals were recruited for the study. Participants were asked to perform the simulations within a specified period and to complete attitudinal questionnaires. Of the 91 pharmacists who volunteered, 72 (79%) completed the simulations and the questionnaires. The practitioners indicated that the simulations adequately tested their knowledge and that they would recommend them to colleagues. Performance scores for data gathering were less than 70%, with no significant differences among the simulations. Case question scores exceeded 80% and again were consistent among simulations, whereas therapy decision scores were more variable, with the lowest scores being recorded for antimicrobial-related simulations. Pharmacists with more hospital experience tended to perform better. Pharmacists completing a patient simulation program found the simulations to be worthwhile. Performance scores indicated some difficulty in gathering patient data and showed that correct therapeutic decisions may not always occur even if adequate information is obtained.

Senior medical students as simulated patients in an objective structured clinical examination: motivation and benefits.

Third and fourth year medical students were recruited to participate as simulated patients and examiners in an Objective Structured Clinical Examination (OSCE) administered for second year medical students. Students reported they were motivated to participate, not only by the honorarium, but because they believed the OSCE would be fun and interesting and because they were interested in medical education and in improving clinical evaluation. The third and fourth year medical students benefitted academically and financially from participation. Faculty benefitted by having a readily available source of enthusiastic and knowledgeable simulated patients.

Dental diagnosis and treatment (DDx & Tx): interactive videodisc patient simulations for dental education.

Judgement skills and critical thinking in dentistry are developed through: (1) a systematic approach to gathering and processing information, and (2) an essential amount of practical experience. A new system of interactive videodisc patient simulations titled 'Dental Diagnosis and Treatment' or 'DDx & Tx' has been developed to provide students or practicing dentists an opportunity to develop and practice their critical thinking skills. The DDx & Tx system consists of patient simulation software, a laser-reflective videodisc with its accompanying database, a patient simulation management system, and documentation. An authoring tool is under development. Faculty-authored simulations require students to gather information, formulate diagnoses, order appropriate treatments and properly sequence those treatments. The students' performance is automatically scored and a critique is provided as a review.

Bacterial contamination and the effect of filters in anaesthetic circuits in a simulated patient model.

In order to investigate bacterial contamination of anaesthetic breathing circuits and means of prevention of this, six different laboratory experiments were performed. These experiments involved the bacterial contamination of Dräger Narkose Spiromat 650 and Dräger AV-1 circle system circuits and of an isolated soda lime carbon dioxide absorber. The effects of anaesthetic gas, gas flow rate and the incorporation of a hydrophobic membrane heat and moisture exchanging bacterial/viral filter (HMEF) at the patient end of these circuits were investigated. It was found that without a HMEF the whole interior of the anaesthetic circuits became contaminated with bacteria. Components closest to the simulated patient showed the highest levels of contamination. Higher gas flows were associated with decreased levels of circuit contamination, presumably because more bacteria were expelled from the system. Halothane (1 volume %) and soda lime were not found to have any demonstrable bactericidal action. The presence of a HMEF between the simulated patient and the Y-piece prevented any detectable contamination from reaching the circuit. Consequently, the presence of a HMEF provides protection of the anaesthetic circuit as well as other patients, healthcare workers and the environment.

Unannounced simulated patients' observations of physician STD/HIV prevention practices.

Studies describing sexually transmitted disease (STD) and human immunodeficiency virus (HIV) prevention practices of primary care physicians have relied on physician or patient reports. This study describes physician STD/HIV prevention practices as observed by unannounced simulated patient evaluators (SPEs). SPEs visited sixty-five primary care physicians. Each SPE portrayed a sexually active female, new to the area, requesting a consultation on STD prevention. One-third of the physicians in the study asked no risk questions, and over 80% failed to ask the SPE specifically about her sexual practices. Most physicians discussed the risks of STDs and HIV and covered basic recommendations (use condoms and know partners better); however, few physicians provided any individualized information or advice about safer sexual practices and the specifics of condom use, such as how to use them or what kind to use. These observations support the low rates of STD/HIV prevention indicated in physicians' self-report and further identify specific deficiencies in the thoroughness of their risk assessment and preventive counseling practices.

Assessing housestaff diagnostic skills using a cardiology patient simulator.

OBJECTIVE: To assess the cardiovascular physical examination skills of internal medicine housestaff. DESIGN: Cross-sectional assessment of housestaff performance on three valvular abnormality simulations conducted on the cardiology patient simulator, "Harvey." Evaluations were done at the beginning (session I) and end (session II) of the academic year. SETTING: Duke University Medical Center internal medicine training program. SUBJECTS: Sixty-three (59%) of 107 eligible internal medicine housestaff (postgraduate years 1 through 3) agreed to participate and completed session I; 60 (95%) completed session II. MEASUREMENTS: All volunteers were tested on three preprogrammed simulations (mitral regurgitation, mitral stenosis, and aortic regurgitation). RESULTS: The overall correct response rates for all housestaff were 52% for mitral regurgitation, 37% for mitral stenosis, and 54% for aortic regurgitation. No difference was noted in correct response rates between sessions I and II. For mitral regurgitation, correct assessment of the contour of the holosystolic murmur predicted a correct diagnosis (P = 0.002). For mitral stenosis, identification of an opening snap and proper characterization of the mitral area diastolic murmur predicted a correct diagnosis (P < 0.0001). No individual observations were noted for the aortic regurgitation simulation, whose identification by the housestaff was associated with a correct diagnosis. CONCLUSIONS: Housestaff had difficulty establishing a correct diagnosis for simulations of three common valvular heart diseases. Accurate recognition of a few "key" observations was associated with a correct diagnosis in two of the three diseases. Teaching housestaff to elicit and interpret a few critical signs accurately may improve their physical diagnosis abilities.

Simulated patients as a learning resource in the study of reproductive medicine.

Simulated patients have been used to foster active learning and problem solving skills in an undergraduate programme of reproductive medicine. These simulators were trained to present a series of clinical problems and were used in a variety of approaches. They served to highlight communication skills and to force attention on the recognition, assessment and management of patient problems.

Assessment of the performance of general practitioners by the use of standardized (simulated) patients.

A study was undertaken whereby a set of standardized (simulated) patients visited general practitioners without being detected, in a health care system where doctors had fixed patient lists. Thirty nine general practitioners were each visited during normal surgery hours by four standardized patients who were designed to be indistinguishable from real patients. The objective of the study was to see whether the actual performance of general practitioners, as assessed by standardized patients, met predetermined consensus standards of care for actual practice. The patients presented standardized accounts of headache, diarrhoea, shoulder pain and diabetes. The mean group scores of the doctors on the predefined standards of care for the different complaints ranged from 33 to 68%. The results show that standardized patients may be the method of choice in the assessment of the quality of actual care of doctors. It is hypothesized that the substandard scores of the doctors do not reflect inadequate competence, but are a result of the difference between competence and performance.

Standardized (simulated) patients' accuracy in recording clinical performance check-list items.

In large-scale performance-based assessment of medical professionals' clinical competence, simulated patients (standardized patients-SPs) are used not only to simulate case problems but also to record on check-list the examinees' clinical performance during their encounter with the SPs. The purposes of this study were to determine the SPs' overall accuracy in recording check-list items, and whether their accuracy was affected by the various characteristics of the check-list, and by the different times during a day and the different days within the examination when the recordings were obtained. Results showed that the SPs' accuracy in recording check-list items was good to very good and was affected by the length of the check-list, as well as by the type and the clarity of the check-list item. It was further found that the SPs' accuracy was consistent and did not vary over the course of a one-day or a 15-day examination.

A method for introducing standardized (simulated) patients into general practice consultations.

A study has been undertaken to determine whether it is possible for a set of standardized (simulated) patients to visit general practitioners, without being detected, in a health care system where doctors have fixed patient lists. Since sending standardized patients into doctors' offices is a new way to assess the performance of general practitioners; this paper describes in detail the methodology that has been used for visits. The paper looks first at the general preparation for visits and secondly at the specific preparation concerning the fine detail of the individual visit. The method was tested in 156 consultations with 39 general practitioners and in no cases were the standardized patients detected. None of the doctors visited felt offended and all were prepared to cooperate in future studies with standardized patients. It is concluded that the standardized patient method, following the step-by-step procedure described, is feasible in actual practice.

An example of lyophilized protein-based materials not simulating patient sera.

Use of reconstituted lyophilized protein-based materials in the clinical laboratory is partly based on the assumption that these materials adequately simulate patients' sera. We examined several of these materials and found that certain ones do not have the same adsorbancies at 340 and 380 nm as do most sera. The implication of this is examined with respect to glucose determination by the hexokinase method on a dual-wave-length blank-subtraction instrument.

Physician attitudes toward relicensure: the simulated patient option.

Primary care physicians in one Southern city were asked to return a mail questionnaire stating their attitudes toward relicensure issues. Respondents overwhelmingly preferred continuing education as the method of creditation for relicensure, but as a second choice preferred the simulated patient procedure to formal examinations. Nearly one half of the respondents agreed to participate in a pilot study of this method. The MD author received more positive replies than the PhD author, possibly because different segments within well matched subsamples were motivated to respond.
