Potentially inappropriate medication use by elderly persons in U.S. Health Maintenance Organizations, 2000-2001.

OBJECTIVES: To determine rates of potentially inappropriate medication use in elderly persons in managed care plans in the United States in 2000-2001. DESIGN: Cross-sectional study using automated medication-dispensing data. SETTING: Ten geographically distributed health maintenance organizations (HMOs). PARTICIPANTS: One hundred fifty-seven thousand five hundred seventeen members aged 65 years and older enrolled in one of the HMOs. MEASUREMENTS: Prevalence of use of 33 potentially inappropriate medications from January 1, 2000 through June 30, 2001. RESULTS: In 2000-2001, 28.8% (95% confidence interval=28.6-29.1) of elderly individuals received at least one of 33 potentially inappropriate medications. This rate ranged from 23.0% to 36.5% across the 10 HMOs. Approximately 5% of elderly patients received at least one of the 11 medications classified by an expert panel as "always avoid," 13% received at least one of the eight medications that would rarely be considered appropriate, and 17% received at least one of the 14 medications that have some indications but are often misused. Overall, rates of use of these medications were greater in women (32.4%) than in men (24.2%). At least 1% of elderly members received belladonna alkaloids (2.3%), dicyclomine (1.1%), or hyoscyamine (1.2%), each of which multiple expert panels have classified as always inappropriate in patients aged 65 years and older. Seven percent of elderly members received propoxyphene, an analgesic medication considered rarely appropriate in the elderly and a drug that has a long history of limited efficacy and potential for toxicity. CONCLUSION: Recent rates of potentially inappropriate medication use by elderly HMO members were at least as great as in a 1996 national sample. This study highlights the need to understand more fully the rationale behind the continued use of these medications.

Health plan members' views on forgiving medical errors.

BACKGROUND: How patients respond to medical errors may influence how physicians approach disclosure of medical errors, but information on patients' responses is limited. Research is needed on how the circumstances that surround a medical error affect how patients respond. OBJECTIVE: To investigate whether patients' tendency to forgive a physician following a medical error varied under different circumstances. STUDY DESIGN: Cross-sectional survey. METHODS: We mailed a questionnaire to 1500 randomly selected health plan members; the response rate was 66%. Questionnaire items assessed the likelihood of forgiveness following a medical error under 12 circumstances drawn from a review of the literature. RESULTS: Respondents were most likely to forgive a physician if the patient failed to provide complete information (93% would or might forgive) and least likely to forgive if the error was due to efforts to keep costs down (11% would or might forgive). Most respondents would not forgive a physician when the physician was tired or distracted (68%), was incomplete in data collection (76%), lacked knowledge (78%), or failed to follow up (85%). Men were more likely to forgive than women; the most educated respondents were most likely to forgive. CONCLUSIONS: Our findings suggest that patients are not likely to forgive a physician in circumstances in which they suspect incompetence, inattention, or a lack of caring on the part of the physician involved. A more comprehensive understanding of forgiveness and the effect of forgiveness on the physician-patient relationship following a medical error is needed.

Health plan members' views about disclosure of medical errors.

BACKGROUND: Various authorities and national organizations encourage disclosing medical errors, but there is little information on how patients respond to disclosure. OBJECTIVE: To examine how the type of error, severity of adverse clinical outcome, and level of disclosure affect patients' responses to error and disclosure. DESIGN: Mail questionnaire survey (8 versions were developed) varying 3 factors in a completely crossed, randomized, factorial design. Each questionnaire included a vignette describing 1) a medical error (failure to check for penicillin allergy or inadequate monitoring of antiepileptic medication); 2) an associated clinical outcome (life-threatening or less serious); and 3) a physician-patient dialogue, with either full disclosure (acceptance of responsibility and an apology) or nondisclosure (expression of regret without acceptance of responsibility or an apology). SETTING: New England-based health plan. PARTICIPANTS: Random sample of 1500 adult members received the questionnaire, with a 66% response rate. MEASUREMENTS: Likelihood of changing physicians, likelihood of seeking legal advice, ratings of patient satisfaction, trust and emotional reaction in response to a vignette and dialogue, and views on medical error and disclosure. RESULTS: Full disclosure reduced the reported likelihood of changing physicians and increased patient satisfaction, trust, and positive emotional response. Full disclosure reduced the reported likelihood of seeking legal advice in only 1 error-and-outcome vignette. In the other vignettes, the percentage of patients indicating that they would seek legal advice was relatively high even with full disclosure. Almost all respondents (98.8%) wanted to be told of errors, most (83%) favored financial compensation if harm occurred, and few (12.7%) favored compensation if no harm occurred. LIMITATIONS: Since the study was done in the context of a managed care plan in one geographic area, it could not assess whether the results are generalizable to other populations. In addition, it could not determine whether responses to the simulated situations used predict responses to real situations. CONCLUSIONS: Patients will probably respond more favorably to physicians who fully disclose medical errors than to physicians who are less forthright, but the specifics of the case and the severity of the clinical outcome also affect patients' responses. In some circumstances, the desire to seek legal advice may not diminish despite full disclosure.

How to design computerized alerts to safe prescribing practices.

BACKGROUND: Medication errors and preventable adverse drug events are common, and about half of medication errors occur during medication ordering. This study was designed to develop and evaluate medication safety alerts and processes for educating prescribers about the alerts. METHODS: At Kaiser Permanente Northwest, a group-model health maintenance organization where prescribers have used computerized order entry since 1996, qualitative interviews were conducted with 20 primary care prescribers. RESULTS: Prescribers considered alerts helpful for providing prescribing and preventive health information. More than half the interviewees stated that it would be unwise to let clinicians control or avoid safety alerts. Common frustrations were (1) being delayed by the alert, (2) having difficulty interpreting the alert, and (3) receiving the same alert repeatedly. Most prescribers preferred small-group educational sessions tied to existing meetings and having local physicians conduct education sessions. DISCUSSION: The findings were used to design a strategy for introducing and promoting the interventions, modifying the alert text and tools, and focusing the education on how clinicians could use the alerts effectively.

Psychometric structure of a comprehensive objective structured clinical examination: a factor analytic approach.

PROBLEM STATEMENT AND BACKGROUND: While the psychometric properties of Objective Structured Clinical Examinations (OSCEs) have been studied, their latent structures have not been well characterized. This study examines a factor analytic model of a comprehensive OSCE and addresses implications for measurement of clinical performance. METHODS: An exploratory maximum likelihood factor analysis with a Promax rotation was used to derive latent structures for the OSCE. RESULTS: A model with two correlated factors fit the data well. The first factor was related to Physical Examination and History-Taking was labeled as information gathering, while the second factor was related to Differential Diagnosis/Clinical Reasoning, and Patient Interaction and was labeled as reasoning and information dissemination. Case Management did not contribute to either factor. The factors accounted for a total 61.6% of the variance in the skills variables. CONCLUSIONS: Recognizing the psychometric components of OSCEs may support and enhance the use of OSCEs for measuring clinical competency of medical students.

Geriatrics training in general internal medicine fellowship programs: current practice, barriers, and strategies for improvement.

To ensure its growth and prosperity, general internal medicine will need to embrace care of the elderly, research on aging, and geriatrics education as components of its core mission. Experts agree that general internal medicine fellows could benefit from increased opportunities in research on aging and geriatrics education; however, important barriers will hamper efforts to integrate geriatrics training into general internal medicine fellowship programs. This article reviews the barriers to integration and proposes solutions for overcoming those barriers. As a result of interviews and meetings with a broad representation of general internists, geriatricians, funding agencies, and policymakers, we propose 2 interventions: 1) the development of institutional program grants to foster collaboration between general internal medicine and geriatrics faculty in the training of general internal medicine fellows and 2) the creation of a 3-year fellowship program combining general internal medicine and geriatrics. This article discusses the importance of evaluating these and other programs intended to increase the geriatrics experience of general internal medicine fellows, and it describes the potential implications of these changes for a broad array of stakeholder institutions.

Decline in fish consumption among pregnant women after a national mercury advisory.

OBJECTIVE: A well-publicized January 2001 federal advisory recommended that pregnant women limit consumption of certain fish because of concerns about mercury contamination. We endeavored to estimate the extent to which pregnant women changed fish consumption habits after dissemination of this national advisory. METHODS: We performed interrupted time series analysis of data from a cohort of pregnant women (2235 who completed at least one dietary questionnaire) visiting obstetric offices in a multispecialty group practice in eastern Massachusetts, surveyed before the advisory from April 1999 through December 2000 and after the advisory from April 2001 through February 2002. Main outcome measures were consumption of total fish and of four fish types: canned tuna, dark meat fish, shellfish, and white meat fish. Subjects reported fish consumption on semiquantitative food frequency questionnaires administered at each trimester of pregnancy. RESULTS: We observed diminished consumption of dark meat fish, canned tuna, and white meat fish after the national mercury advisory. These decreases resulted in a reduction in total fish consumption of approximately 1.4 servings per month (95% confidence interval 0.7, 2.0) from December 2000 to April 2001, with ongoing declines through the end of the study period. There was no change in shellfish intake. CONCLUSION: After dissemination of federal recommendations, pregnant women in this cohort reported reduced consumption of fish, including tuna, dark meat fish, and white meat fish. Because these fish may confer nutritional benefits to mother and infant, public health implications of these changes remain unclear.

Variation in predictors of primary care career choice by year and stage of training.

CONTEXT: It is not known whether factors associated with primary care career choice affect trainees differently at different times or stages of medical education. OBJECTIVE: To examine how role models, encouragement, and personal characteristics affect career choice at different stages (medical school vs residency) and periods (1994 vs 1997) of training. DESIGN: A split-panel design with 2 cross-sectional telephone surveys and a panel survey in 1994 and 1997. PARTICIPANTS: A national probability sample of fourth-year students (307 in 1994, 219 in 1997), 645 second-year residents in 1994, and 494 third-year residents in 1997. Of the fourth-year students interviewed in 1994, 241 (78.5%) were re-interviewed as third-year residents in 1997. MAIN OUTCOME MEASURE: Primary care (general internal medicine, general pediatrics, or family medicine) career choice. RESULTS: Having a primary care role model was a stronger predictor of primary care career choice for residents (odds ratio [OR], 18.0; 95% confidence interval [95% CI], 11.2 to 28.8 in 1994; OR, 43.7; 95% CI, 24.4 to 78.3 in 1997) than for students (OR, 6.5; 95% CI, 4.3 to 10.2; no variation by year). Likewise, peer encouragement was more predictive for residents (OR, 5.4; 95% CI, 3.3 to 8.9 in 1994; OR, 16.6; 95% CI; 9.7 to 28.4 in 1997) than for students (OR, 2.1; 95% CI, 1.3 to 3.2; no variation by year). Orientation to the emotional aspects of care was consistently associated with primary care career choice across stages and years of training. CONCLUSIONS: The effect of peer encouragement and role models on career choice differed for students and residents and, in the case of residents, by year of training, suggesting that interventions to increase the primary care workforce should be tailored to stage of training.

How do precepting physicians select patients for teaching medical students in the ambulatory primary care setting?

OBJECTIVE: To study how clinical preceptors select patients for medical student teaching in ambulatory care and to explore key factors they consider in the selection process. DESIGN: Qualitative analysis of transcribed interviews. SETTING: Harvard Medical School, Boston, Mass. PARTICIPANTS: Nineteen physicians (14 general internists and 5 general pediatricians) who serve as clinical preceptors. MEASUREMENTS: Responses to in-depth open-ended interview regarding selection of patients for participation in medical student teaching. MAIN RESULTS: Preceptors consider the competing needs of the patient, the student, and the practice the most important factors in selecting patients for medical student teaching. Three dominant themes emerged: time and efficiency, educational value, and the influence of teaching on the doctor-patient relationship. These physicians consciously attempt to select patients whose participation in medical student teaching maximizes the efficiency of the clinical practice and optimizes the students' educational experiences, while minimizing any potential for harming the relationship between preceptor and patient. CONCLUSIONS: These findings may help validate the frustration preceptors frequently feel in their efforts to teach in the outpatient setting. Becoming more cognizant of the competing interests-the needs of the patient, the student, and the practice-may help physicians to select patients to enhance the educational experience without compromising efficiency or the doctor-patient relationship. For educators, this study suggests an opportunity for faculty development programs to assist the clinical preceptor both in selecting patients for medical student teaching and in finding ways to maximize the efficiency and educational quality of the outpatient teaching environment.

Quality and correlates of medical record documentation in the ambulatory care setting.

BACKGROUND: Documentation in the medical record facilitates the diagnosis and treatment of patients. Few studies have assessed the quality of outpatient medical record documentation, and to the authors' knowledge, none has conclusively determined the correlates of chart documentation. We therefore undertook the present study to measure the rates of documentation of quality of care measures in an outpatient primary care practice setting that utilizes an electronic medical record. METHODS: We reviewed electronic medical records from 834 patients receiving care from 167 physicians (117 internists and 50 pediatricians) at 14 sites of a multi-specialty medical group in Massachusetts. We abstracted information for five measures of medical record documentation quality: smoking history, medications, drug allergies, compliance with screening guidelines, and immunizations. From other sources we determined physicians' specialty, gender, year of medical school graduation, and self-reported time spent teaching and in patient care. RESULTS: Among internists, unadjusted rates of documentation were 96.2% for immunizations, 91.6% for medications, 88% for compliance with screening guidelines, 61.6% for drug allergies, 37.8% for smoking history. Among pediatricians, rates were 100% for immunizations, 84.8% for medications, 90.8% for compliance with screening guidelines, 50.4% for drug allergies, and 20.4% for smoking history. While certain physician and patient characteristics correlated with some measures of documentation quality, documentation varied depending on the measure. For example, female internists were more likely than male internists to document smoking history (odds ratio [OR], 1.90; 95% confidence interval [CI], 1.27 - 2.83) but were less likely to document drug allergies (OR, 0.51; 95% CI, 0.35 - 0.75). CONCLUSIONS: Medical record documentation varied depending on the measure, with room for improvement in most domains. A variety of characteristics correlated with medical record documentation, but no pattern emerged. Further study could lead to targeted interventions to improve documentation.

How well do second-year students learn physical diagnosis? Observational study of an Objective Structured Clinical Examination (OSCE).

BACKGROUND: Little is known about using the Objective Structured Clinical Examination (OSCE) in physical diagnosis courses. The purpose of this study was to describe student performance on an OSCE in a physical diagnosis course. METHODS: Cross-sectional study at Harvard Medical School, 1997-1999, for 489 second-year students. RESULTS: Average total OSCE score was 57% (range 39-75%). Among clinical skills, students scored highest on patient interaction (72%), followed by examination technique (65%), abnormality identification (62%), history-taking (60%), patient presentation (60%), physical examination knowledge (47%), and differential diagnosis (40%) (p <.0001). Among 16 OSCE stations, scores ranged from 70% for arthritis to 29% for calf pain (p <.0001). Teaching sites accounted for larger adjusted differences in station scores, up to 28%, than in skill scores (9%) (p <.0001). CONCLUSIONS: Students scored higher on interpersonal and technical skills than on interpretive or integrative skills. Station scores identified specific content that needs improved teaching.

The relationship between second-year medical students' OSCE scores and USMLE Step 1 scores.

The relationship between objective structured clinical examinations (OSCEs) and standardized tests is not well known. We linked second-year medical students' physical diagnosis OSCE scores from 1998, 1999 and 2000 (n = 355) with demographic information, Medical College Admission Test (MCAT) scores, and United States Medical Licensing Examination (USMLE) Step 1 scores. The correlation coefficient for the total OSCE score with USMLE Step 1 score was 0.41 (p < 0.001). Two of 7 skills areas-diagnosis and identification of abnormality-were significant multivariate correlates of USMLE Step 1 score. OSCE station scores accounted for approximately 22% of the variability in USMLE Step 1 scores. A second-year OSCE in physical diagnosis is correlated with scores on the USMLE Step 1 exam, with skills that foreshadow the clinical clerkships most predictive of USMLE scores. This correlation suggests predictive validity of this OSCE and supports the use of OSCEs early in medical school.

Communicating with patients about medical errors: a review of the literature.

BACKGROUND: Ethical and professional guidelines recommend disclosure of medical errors to patients. The objective of this study was to review the empirical literature on disclosure of medical errors with respect to (1) the decision to disclose, (2) the process of informing the patient and family, and (3) the consequences of disclosure or nondisclosure. METHODS: We searched 4 electronic databases (MEDLINE, CINAHL, PsycINFO, and Social Sciences Citations Index) and the reference lists of relevant articles for English-language studies on disclosure of medical errors. From more than 800 titles reviewed, we identified 17 articles reporting original empirical data on disclosure of medical errors to patients and families. We examined methods and results of the articles and extracted study designs, data collection procedures, populations sampled, response rates, and definitions of error. RESULTS: Available research findings suggest that patients and the public support disclosure. Physicians also indicate support for disclosure, but often do not disclose. We found insufficient empirical evidence to support conclusions about the disclosure process or its consequences. CONCLUSIONS: Empirical research on disclosure of medical errors to patients and families has been limited, and studies have focused primarily on the decision stage of disclosure. Fewer have considered the disclosure process, the consequences of disclosure, or the relationship between the two. Additional research is needed to understand how disclosure decisions are made, to provide guidance to physicians on the process, and to help all involved anticipate the consequences of disclosure.
