Psychometric characteristics of a write-up assessment form in a medicine core clerkship.

BACKGROUND: Case write ups are ubiquitous in medicine clerkships, yet few studies have examined how they are assessed. PURPOSE: To examine the feasibility, reliability, and validity of scores on a new write-up assessment form. METHODS: In 2002, medicine core clerkship students (n = 165) submitted 3 patient write ups (n = 493). Each was graded using a 14-item form and given a Global Write-Up Assessment. Final Global Write-Up grades were correlated to National Board of Medical Examiners medicine subject exam scores and multiple clerkship ratings. RESULTS: For most items on the form, the full 4-point rating range was used. The reproducibility coefficient was .67 (SE = .12). Final Global Write-Up grades were correlated with exam scores (r = .35, p < .05) and inpatient (r = .28, p < .05) and outpatient (r = .16, p < .05) course grades. CONCLUSIONS: The write-up assessment form, as used in a design with multiple write ups and raters, provides relatively precise estimates of performance and can be used to assess written documentation skills.

Literacy and knowledge, attitudes and behavior about mammography in Latinas.

This cross-sectional study explored the association between functional health literacy and the knowledge, beliefs, attitudes, and behavior about mammography and self-breast examination in a sample of Latinas attending community health clinics in Philadelphia. The results show that 70% of Latinas had inadequate or marginal functional health literacy. In Latinas, functional health literacy is only weakly associated with knowledge and not associated with beliefs and attitudes about screening mammography, but is significantly associated with having ever had a mammogram. After adjusting for demographic characteristics, functional health literacy was significantly associated with having ever had a mammogram (odds ratio [OR] 1.14, 95% confidence interval [CI] 1.02-1.27). These findings suggest that Latinas with poor functional health literacy are less likely to undergo mammography. Future research should target increasing the knowledge about and rates of screening mammography in patients with low functional health literacy.

Measuring adherence to mammography screening recommendations among low-income women.

OBJECTIVES: (1) To describe the accuracy of self-report and administrative claims for measuring mammography adherence among low-income women; (2) to determine whether the accuracy of self-report differed between telephone interview and mailed questionnaire; and (3) to explore whether the method of measuring adherence affected associations between mammography adherence and participant sociodemographic characteristics. DESIGN: Retrospective cohort study of women receiving care from a Philadelphia Medicaid Managed Care Organization (MCO). PARTICIPANTS: Three hundred and ninety-nine low-income women eligible for screening mammography of whom 64% were African American, 14% Caucasian, 13% Hispanic, and 8% Asian American. MEASURES: Self-reported use of mammography screening, administrative mammography claims data, and dates of mammograms from radiology facility records. The "gold standard" categorized women as having undergone screening if they had either a billing claim or facility record for a mammogram in the past 12 months. MAIN RESULTS: Two hundred and eighty-three of the 399 women reported having had a mammogram in the past 12 months. The sensitivity of self-report was 0.93, specificity was 0.54, positive predictive value was 0.70, and negative predictive value was 0.86. One hundred and seventy-nine of the 399 women had a claim for a mammogram in the past 12 months. The sensitivity of claims data was 0.83 with a negative predictive value of 0.84. The sensitivity of self-report was higher with telephone data collection (0.98) than with mailed data collection (0.82), while the specificity was higher with mail (0.64) than telephone (0.50). African American race was associated with adherence to screening recommendations when mammography use was measured by self-report (RR 1.31, P = 0.002) but not when it was measured by claims or facility validation (RR 1.03, P = 0.56, and RR 1.12, P = 0.15, respectively). CONCLUSIONS: Accurate measurement of adherence to mammography screening among low-income women is difficult. Self-report substantially overestimates adherence (particularly when collected through telephone interviews), while also misclassifying some women who underwent screening as not having been screened (particularly when collected through mailed questionnaires). In contrast, administrative claims data substantially underestimates adherence. Inaccurate measurement of mammography adherence can lead to a biased understanding of the factors associated with adherence.

Sleep behaviors and attitudes among internal medicine housestaff in a U.S. university-based residency program.

PURPOSE: Physicians-in-training are susceptible to fatigue given their prolonged duty hours. Sleep deprivation has been shown to alter perceptions of sleepiness and performance. This study examined the state of sleepiness and attitudes about sleep and performance of work- and non-work-related tasks among incoming and current housestaff; and how rotation, call cycle, and call status are related to acute and chronic sleep deprivation and perceptions of sleepiness. METHOD: A survey instrument was administered in June 2001 to 53 incoming interns and 79 current housestaff at the University Pennsylvania School of Medicine, a university-based internal medicine residency program. RESULTS: All 132 participants (100%) completed the instrument. Acute sleep deprivation was experienced by 34% of the current housestaff and 64% of current housestaff were chronically sleep deprived. Current housestaff admitted to the possibility of dozing while performing various work-related tasks such as writing notes in charts (69%), reviewing medication lists (61%), interpreting labs (51%), and writing orders (46%). At least half of all respondents felt their patients received good care despite residents' sleepiness and as many believed sleep deprivation was a necessary part of training. Nearly half (48%) of current housestaff rotating on a ward service reported acute sleep deprivation, as did 81% of those who were postcall. Over two-thirds of the housestaff on wards and in the ICU reported chronic sleep deprivation. Subjective sleepiness did not vary much across rotations, call cycle, and call status. CONCLUSION: Chronic and acute sleep deprivation contribute to residents' fatigue. Education could be targeted at attitudes. Further investigation of factors contributing to chronic sleep deprivation in this population is warranted.

A RIME perspective on the quality and relevance of current and future medical education research.

In this article, the authors consider the quality and relevance of current and future medical education research by (1) presenting a framework for medical education research and reviewing basic principles of "good" empirical work, (2) extending the discussion of principles to "best practices," (3) considering the distinctive features of medical education that present challenges to the researcher, and (4) discussing opportunities for expanding the scope and influence of medical education research. Their audience is intended to be clinicians involved in education, deans and associate deans who create and direct educational curricula and processes, and those from offices critical to the educational mission such as admissions, student services and financial aid, as well as medical education researchers. The authors argue that the quality and relevance of current work can be enhanced when research is situated within a general framework and questions are asked that are based on literature and theory and push the field toward new knowledge. Obviously methods and designs must be appropriate and well-executed and sufficient data must be gathered. Multiple studies are highlighted that showcase the rigor and creativity associated with excellent quality work. However, good research is not without its challenges, most notably short timelines and the need to work within an ever-changing real-life educational environment. Most important, the field of medical education research has many opportunities to increase its impact and advance its quest to study important learners' behaviors and patients' outcomes. Programs to train and collaborate with clinical and administrative colleagues, as well as researchers in other fields, have great potential to improve the quality of research in the field.

The impact of resident duty hour reform in a medicine core clerkship.

PROBLEM STATEMENT: Residency programs have changed to comply with resident duty hour regulations. This study's purpose was to determine if there are differences in medicine clerkship students' activities, associations, and perceptions of educational value before and after duty hour reform. METHOD: Medicine clerkship students, both before (n = 36) and after (n = 33) duty hour reform, wore random reminder pagers for one week and completed time allocation surveys with each signal. Event proportions were calculated and analysis of variance assessed group differences. RESULTS: A total of 804 and 912 surveys were completed before and after reform, respectively. No differences existed in proportion of time for direct patient care (.13 versus.14, p =.35), indirect patient care (.35 versus.32, p =.21), and education (.38 versus.37, p =.69) activities, students' associations, educational value, and time in the hospital before and after reform. CONCLUSIONS: Residency program changes had minimal impact on medicine clerkship students.

Development and testing of the health care system distrust scale.

BACKGROUND: Distrust of the health care system may be a significant barrier to seeking medical care, adhering to preventive health care and treatment regimens, and participating in medical research. OBJECTIVE: To describe the development and psychometric testing of an instrument (the Health Care System Distrust Scale) to measure distrust of the health care system. METHODS: Scale development involved 2 phases. In Phase 1, a pilot instrument was developed based on a conceptual model of health care-related distrust. Draft items were created using focus group sessions with members of the general public, literature review, and expert opinion. Draft items were pilot tested with 55 individuals waiting to be assigned to jury duty at the Municipal Court of Philadelphia. A priori, candidate items for elimination or revision included those with >5% missing data, extremely low or high interitem or item-total correlations, or those having a negative effect on the scale's internal consistency. In Phase 2, we conducted a survey of 400 prospective jurors to assess the reliability and validity of the final scale scores. RESULTS: In Phase 1, a 10-item scale was constructed that included 4 items measuring honesty, 2 items measuring confidentiality, 2 items measuring competence, and 2 items measuring fidelity. The participants in Phase 2 had a mean age of 41 years. Forty-three percent were African-American, 45% white, and 4% Hispanic. Scores on the Health Care System Distrust scale ranged from 12 to 46 with a possible range from 10 to 50. The mean score was 29.4 with a standard deviation of 6.33. No item had over 5% missing data. Internal consistency (Cronbach's alpha) was 0.75. Item-total correlations ranged from 0.27 to 0.57. Principal components analysis revealed 1 general component accounting for 32% of the variance. Nine of the variables had loadings higher than 0.40. As predicted, distrust of the health care system was higher among African Americans than whites and was inversely correlated with trust in personal physicians. CONCLUSIONS: Initial testing suggests that we developed an instrument with valid and reliable scores in order to measure distrust of the health care system. Future research is needed to evaluate the validity and reliability of the Health Care System Distrust scale among diverse populations. This instrument can facilitate the investigation of the prevalence, causes, and effects of health care system distrust in the United States.

Program directors' views of the importance and prevalence of mentoring in internal medicine residencies.

Program directors establish priorities for residency programs. Their views of mentoring likely influence the tone about and availability of mentoring programs. This survey to all internal medicine program directors assessed attitudes toward mentoring, existence of formal mentoring programs, and features of the mentoring programs. The response was 60%. The majority (>60%) favored mentoring. Forty-nine percent of the residencies had structured mentoring programs. Programs differed in frequency of meetings, use of evaluations, and presence of curriculum. Overall, although program directors' attitudes are favorable and at least half have formal mentoring programs, the programs are largely unstructured, loosely monitored, and underevaluated.

The development of a rapid screen for caregiver burden.

OBJECTIVES: To develop a shortened screen for burden associated with caring for a patient with Alzheimer's disease (AD). DESIGN: Cross-sectional. SETTING: The Memory Disorders Clinic of an AD center. PARTICIPANTS: Two hundred fifty-one AD patient-caregiver dyads. MEASUREMENTS: Screen for Caregiver Burden (SCB), Center for Epidemiologic Studies Depression scale, Medical Outcomes Short Form, Mini-Mental State Examination, and patient and caregiver characteristics. RESULTS: At least 25% of the sample endorsed eight of the 25 items in the SCB subjective burden (SB) scale. Of these eight items with a prevalence of 25% or greater endorsement, seven items had item-total correlations of 0.55 or greater. The shortened seven-item SCB SB had an alpha of 0.86, indicating that the shortened scale has good internal consistency (Full SCB SB alpha=0.88). The seven-item SCB SB was highly associated with depression and overall mental health measures. CONCLUSION: This shortened version of the SCB allows a clinician to rapidly assess the burden associated with caregiving for a person with AD.

Effect of race on ratings of hypothetical candidates for a research scholarship/research assistant position.

BACKGROUND: Study of the racial-ethnic biases of medical students is necessary to further understand health disparities. The objectives of this study were to (a) determine if medical students exhibit racial biases, (b) assess whether there are differences in racial biases among medical students who have and have not received a curriculum in cultural sensitivity, and (c) determine if these findings vary by student race-ethnicity. DESCRIPTION: We evaluated medical students' preferences in hiring hypothetical candidates for a research scholarship and a research assistant position. Each student received a packet containing four curricula vitae (CVs) with attached photographs. Three CVs and photographs were identical. The fourth CV was identical, but in half the packets the photograph was of an African American man and in the other half of a White man. Students were asked to provide ratings of suitability. EVALUATION: The African American candidate received better ratings than the White candidate. There were no differences in the ratings by student curriculum receipt or race-ethnicity. CONCLUSION: We found no evidence that an African American candidate was discriminated against by medical students.

Health care economics, financing, organization, and delivery.

BACKGROUND: The US health care system is in a state of rapid evolution, with changing payment, organizational, and management structures. To learn how to function optimally in a system in which care is increasingly managed and competitive, today's medical students must understand the structural and economic underpinnings of the system within which they will practice. At the outset of the Undergraduate Medical Education for the 21st Century (UME-21) project, the great majority of medical school curricula were lacking in areas of health care financing and organizational structure. The institutions involved in the UME-21 project sought to address curricular deficiencies in two broad areas: (1) the structure and financing of the US health care system ("health policy") and (2) the manner in which this system is reflected in the organization and activities of health care providers ("care delivery"). This article discusses the development, implementation, and evaluation of the first of the two areas. METHODS: Data were abstracted from written reports provided by each of the UME-21 schools to the project's Executive Committee and sponsor. In selected cases, additional data were obtained by personal communications with project directors and evaluators. Local UME-21 project leaders verified all data presented. RESULTS: Curricular philosophy and teaching methods varied widely, but health policy curricula were predominantly preclinical and didactic in nature. At the school level, much was achieved in terms of student knowledge, curricula were generally well received by students, attitudes toward managed care generally moved in a positive direction, and behavior may have been positively influenced as well. At the project level, many potentially interesting changes exist within the 18 schools and between the UME-21 and other schools, but it is not clear whether or what parts of the health policy curricula were responsible for these changes. Nonetheless, as measured by changes in health policy-related items on the Association of American Medical Colleges Graduation Questionnaire, it appears that UME-21 schools outperformed their non-UME-21 counterparts. All of the UME-21 schools were enthusiastic about their health policy innovations, and this extended across all key stakeholders. Most schools avoided focusing on managed care and instead adopted more neutral themes that introduced the same material. Integrating the new material in conjunction with the more traditional aspects of the curriculum was also an effective implementation strategy. CONCLUSIONS: Health policy should be incorporated into both the preclinical and clinical years. The former emphasizes health care economics as one of the foundations of medical practice, whereas the latter provides the opportunity for its use on a daily basis in clinical settings. However, like any new curriculum, to achieve equal status with the traditional biomedical curriculum, it must be presented in a scholarly, rigorous, and reasonably comprehensive fashion. Mounting a scholarly health policy curriculum requires a wide-ranging, interdisciplinary faculty. If it is to become a central component of the medical school curriculum, creative approaches to faculty recruitment and development will be needed. This will require both careful educational policy formulation and new investment.

UME-21 local evaluation initiatives: contributions and challenges.

BACKGROUND AND OBJECTIVES: The 18 medical schools involved in the UME-21 initiative developed innovative curricula and evaluation strategies. While there was significant variation in how schools approached the evaluation process, there were common methodological issues and challenges affecting the reliability of scores and validity of interpretations regarding outcomes. This paper explores these issues and challenges, using experiences from selected UME-21 schools. METHODS: Four evaluation issues and strategies are discussed: instrument development, study design, process evaluation using formative evaluation methods, and qualitative strategies. Within each discussion, examples from a UME-21 school are presented. RESULTS: The four evaluation strategies offered the flexibility to match local evaluation needs with an effective approach to evaluations. CONCLUSIONS/IMPLICATIONS: The school-level evaluation requirements by the UME-21 initiative provided schools the flexibility to design individualized evaluation strategies, yet also encouraged collaboration among evaluators. While this strategy resulted in many successes at the school level, it also served to identify common methodological challenges that can be used as a guide for other schools in implementing and evaluating curricula.

Assessing health literacy in African American and Caucasian adults: disparities in rapid estimate of adult literacy in medicine (REALM) scores.

BACKGROUND AND OBJECTIVES: The influence of literacy on health and health care is an important area of investigation. Studies with a literacy focus are most valuable when literacy is assessed with psychometrically sound instruments. METHODS: This study used a prospective cohort sample of 1,610 primary care patients. Patients provided sociodemographics and took the Rapid Estimate of Adult Literacy in Medicine (REALM), a 66-item word pronunciation literacy test. RESULTS: The sample was 65% African American; 66% were men; 51% had a high school education or less. REALM scores were significantly related to education, age, and race but not gender. When stratified by education, differences between African Americans and Caucasians remained significant. Using 19 different strategies to shorten the 66-item instrument, reliability coefficients above.80 were maintained. CONCLUSIONS: The REALM is a robust assessment of health literacy. However, the discordance in scores between African Americans and Caucasians with similar educational attainment needs to be further addressed. A much shorter instrument would still have internally consistent scores and potentially be more useful in clinical settings.

Designing an illustrated patient satisfaction instrument for low-literacy populations.

Up to 25% of adults in the United States have difficulty with everyday reading tasks. As patients, adults with low literacy may not be able to complete many self-administered written questionnaires, which often are used to obtain information from patients and to gauge their satisfaction with care. We developed an illustrated version of a patient satisfaction instrument used by the Veterans Health Administration. This paper describes the extensive design process used to develop, pilot-test, and revise this 63-item illustrated instrument. A total of 438 patients were interviewed over a 1-year period to obtain feedback on illustrations, with at least 15 people viewing and commenting on each picture and revision. All pictures were revised, with the majority revised at least 4 times. We report on this iterative design process as well as on lessons we learned in illustrating questions for low-literacy populations.
