Cancer control knowledge, attitudes, and perceived skills among medical students.

BACKGROUND: The Cancer Prevention and Control Education (CPACE) program aims to strengthen and coordinate curriculum offerings in cancer prevention and control for medical, graduate nursing and public health students. METHODS: Students were surveyed on cancer-related knowledge and confidence as part of needs assessment and evaluation efforts. The students completed self-administered surveys (response rate 78%). Descriptive and stratified analysis and ANOVA were conducted. RESULTS: Knowledge and confidence generally increased with each successive class year, but confidence varied markedly across specific counseling scenarios and by gender. While the students overall reported greater confidence in performing an examination than in interpreting the results, confidence varied significantly across specific types of examinations. CONCLUSIONS: Understanding of basic information about common cancers was disappointing. Confidence to perform and interpret examinations could be higher, especially for opposite-gender screening examinations. Implications of the findings for CPACE curriculum development are discussed.

The patient exit interview as an assessment of physician-delivered smoking intervention: a validation study.

In evaluating the efficacy of physician-delivered counseling interventions for health behavior changes such as smoking cessation, a major challenge is determining the degree to which interventions are implemented by physicians. The Patient Exit Interview (PEI; J. Ockene et al., 1991) is a brief measure of a patient's perception of the content and quantity of smoking cessation intervention received from his or her physician. One hundred eight current smokers seen in a primary care clinic completed a PEI following their physician visit. Participants were 45% male, 95% Caucasian, with a mean age of 42 years and an average of 22 years of smoking. The PEI correlated well with a criterion measure of an audiotape assessment of the physician-patient interaction (r = .67, p < .001). When discrepancy occurred, in general it was due to patients' over-reporting of intervention as compared with the criterion measure. Implications and limitations of these findings are discussed.

Faculty development for community-based physicians at the University of Massachusetts and SUNY-Buffalo.

Community-based faculty development (CBFD) is becoming increasingly important as medical education moves into the ambulatory/office-based setting CBFD provides preceptors with essential knowledge, skills, and attitudes directly related to teaching while providing a sense of identity as teachers to a diverse group of practitioners in a variety of settings. This article reviews the structure and function of successful community-based faculty development, using as examples programs from the University of Massachusetts Medical School and the State University of New York at Buffalo that were supported by The Robert Wood Johnson Foundation's Generalist Physician Initiative. After reviewing the literature on successful implementation of programs dedicated to community-based precepting, the authors investigate the educational concepts, instructional designs, and operational characteristics that are the framework for providing successful faculty development to community-based preceptors. They list rationales and examples of the educational methods used and compare structural components of the programs at both institutions. Last, they explore future directions in the rapidly changing medical education environment that need to be addressed in CBFD in the areas of outcome/program evaluation, comprehensive needs assessment, and regionalization.

The relationship between smoking, cholesterol, and HDL-C levels in adult women.

The purpose of this study was to determine the independent relationship between smoking quantity and cholesterol (TC) and lipoprotein levels (HDL-C) in women. A total of 805 female subjects were grouped as: non-smokers, ex-smokers, light smokers, moderate smokers, and heavy smokers. TC and HDL-C were examined before and after controlling for the coexisting risk factors of age, body composition, fitness level, dietary fat intake, family history of coronary artery disease, oral contraceptive, and alcohol use. Preliminary analysis demonstrated significant differences (p < .01) in TC between heavy smokers and all other groups and significant differences in HDL-C between heavy to moderate smokers and ex- and non-smokers. After adjusting for confounding variables, the differences in TC and HDL-C remained unchanged between the groups. It was concluded that heavy to moderate smoking was independently associated with higher TC and lower HDL-C levels, and that smoking abstinence or smoking cessation may be associated with healthier lipoprotein profiles in adult women. Based on these findings, it was recommended that employers consider the provision of health promotion programs including seminars, behavioral modification workshops, as well as financial incentives for employees to stop smoking.

The Physician-Delivered Smoking Intervention Project: factors that determine how much the physician intervenes with smokers.

OBJECTIVE: To determine factors that affect how much physicians trained to use a patient-centered smoking intervention intervene with their smoking patients. DESIGN: Forty internal medicine residents and ten internal medicine attending physicians trained in a patient-centered counseling approach were randomized to an algorithm condition (provision of intervention algorithm at each patient visit) or a no-algorithm condition. Smoking intervention steps used by physicians with patients were assessed with Patient Exit Interviews (PEIs). SETTING: Ambulatory clinic; academic medical center. PATIENTS: Five hundred twenty-seven adult smokers seen in clinic between June 1990 and April 1992. MAIN RESULTS: There was no difference in overall PEI scores or in individual PEI steps taken between the algorithm and no-algorithm conditions. Two patient baseline factors (reporting thinking of stopping smoking within six months and higher Fagerstrom Tolerance Score) and one physician factor (older age) were significantly predictive of higher PEI score. CONCLUSION: Provision of an intervention algorithm at each patient visit does not increase the likelihood that trained physicians who are cued to intervene will perform more of the intervention steps taught. Trained physicians are more likely to intervene with smokers who are more nicotine-dependent and who expect and desire to stop smoking.

Expectations and outcomes after hip fracture among the elderly.

Hip fractures among the elderly are a common occurrence, with high social and personal costs. Sequelae not infrequently include loss of independent functioning, permanent disability, and death. This prospective study of a cohort of eighty recently diagnosed "hardy" hip fracture patients examines initial rehabilitation expectations using a combination of methods. The study addresses the relationship between initial expectations and changes in ambulatory status from prefracture to three months post-fracture. The importance of previous experience with illness is also explored. Participants who had positive expectations for recovery and those who had greater previous experience were likely to have less negative change in ambulation from prefracture to three months, and better overall ambulation at three months. The findings suggest a relationship between patient expectations for recovery and actual recovery of ambulation, and support the heretofore "clinical impression" that cognition and affect influence the course of rehabilitation after hip fracture.

Finding meaning after the fall: injury narratives from elderly hip fracture patients.

Hip fractures occur frequently among the elderly, often with severe medical, psychological and social repercussions. This research takes a new look at hip fracture rehabilitation, focusing on meanings and post-fracture prognostic indicators. An innovative methodological approach to narrative analysis is employed which combines ethnographic and epidemiologic techniques. Analyses of injury narratives from 80 elderly subjects interviewed soon after initial hospitalization are presented, focusing on three categories of meaning: explanatory models, sense of disability, and futurity. Insights from these narratives, as well as from questionnaires and observations, shed light on the experience of hip fracture for the elderly. In addition, aspects of the initial narratives are considered in relation to ambulation outcomes at 3 and 6 months. Those individuals who perceive their problem in a more external or mechanical fashion (caused by the environment) show greater improvement in ambulation at 3 and 6 months relative to those who show no evidence of this thinking or who perceive it as an internal or organic problem (in terms of disease or illness). Greater improvement in ambulation at 3 and 6 months is also noted for subjects whose perception of disability was consistent with more autonomy, independence, and a sense of connection with the world around them. The present study demonstrates the potential utility of narrative analysis as a data reduction approach. It also suggests the possibility of new psychosocial prognostic factors for hip fracture rehabilitation.

Training family practice and internal medicine residents to counsel patients who smoke: improvement and retention of counseling skills.

This investigation builds on an earlier study by describing the final results of a training program that teaches internal medicine and family practice residents to counsel patients to stop smoking. In this study, 198 residents participated in a three-hour training program which included small group discussion and role-playing exercises. Videotaped observations of role-playing performances were used to assess behavioral outcomes related to counseling skills for 104 residents who completed pre-, immediate post-, and long-term follow-up testing. The present findings support previous results that show the training program has a significant positive effect on physician smoking cessation counseling skills. A subsample of residents continued to exhibit improved counseling skills one year after the initial educational interventions, suggesting that these skills can be retained over time.

Surgeon and family physician opinions of the general surgical needs of family practice residents: a pilot study.

There is a lack of data assessing needs and evaluating educational objectives in general surgery for family practice residents. Studies suggest that family practice residency graduates feel underprepared in some surgical areas. This study provides results of a survey of 28 surgeons, practicing family physicians and family practice residents in the Northeast regarding the importance of 166 surgical objectives. The groups are compared to each other to detect differences in perceptions about what family practice residents should be taught in general surgery. Surgeons attached significantly less importance to nine of 21 general categories of learning objectives (e.g. emergency skills) than did practicing family physicians or family practice residents. No differences in ratings of surgical objectives were observed for 12 of 21 general categories.

Acquired hypophosphataemic vitamin D resistant rickets in black children.

The case histories of five black children aged between 4 1/2 and 9 years, with acquired hypophosphataemic vitamin D resistant rickets are presented. Muscle weakness was a striking feature clinically, while radiographically all had marked osteopenia in association with classical florid rickets. Biochemically, they were normocalcaemic and hypophosphataemic, with normal parathyroid hormone concentrations. In three of the children 1,25-dihydroxyvitamin D concentrations were low. One child responded to no specific therapy, while three required continuous 1 alpha-hydroxyvitamin D and oral phosphate supplementation, and the fifth 1 alpha-hydroxyvitamin D therapy alone before the clinical, biochemical and radiographic picture responded. The features in three of the children resemble oncogenous rickets, but the features of the other two do not fit any known aetiology. Although the group as a whole may be heterogeneous, until the pathogenetic mechanisms are determined, the authors believe they should be grouped together as acquired hypophosphataemic vitamin D resistant rickets.

Mechanisms of anemia in protein-energy malnutrition in Johannesburg.

Studies of red cell metabolism, erythropoeitin concentration, iron and folate status were made in 48 children with protein-energy malnutrition in Johannesburg (altitude 1800 m). Biochemical evidence of iron deficiency was presented in 26% cases on admission and developed in 90% during recovery. Biochemical evidence of folate deficiency was present in 14% of cases on admission and resolved on dietary therapy alone. Serum erythropoeitin was increased on admission and remained elevated during recovery. There was no relationship between serum erythropoeitin and Hb concentrations. Key enzymes in the red cell glycolytic and hexose monophosphate pathways and red cell membrane showed increased activity. Red cell adenosine triphosphate concentration was increased and unstable. Red cell potassium was decreased and, in the fatal cases, red cell sodium was increased. The possible significance and practical implications of these findings are discussed.
