How medical students' trauma histories affect their clinical clerkship experiences

BACKGROUND

As the gender demographics of medical students have evolved over the past decades, it is important to understand potential stressors and challenges that may affect clinical learning experiences. This study investigated the prevalence of prior sexual assault (SA) and interpersonal violence (IPV) in medical students and how these affect their clinical clerkship experiences.

METHODS

A survey was distributed to third- and fourth-year medical students at a single institution in August 2022 querying respondents on demographics and prior experiences with SA/IPV at any point in their lives. Respondents who indicated they had previously experienced SA/IPV were directed to questions about how these experiences affected clerkships.

FINDINGS

Of 419 students, 125 responded to the survey (30.8% response rate). Forty (31.1%) reported a history of SA/IPV-32 (80.0%) women, five (12.5%) men, and three (7.5%) who did not report gender or identified as non-binary. Of the 40 respondents with a history of SA/IPV, 20 (50.0%) reported that their prior history affected their overall clinical experience, and nine (22.5%) felt that it affected their performance. Only seven (17.5%) reported using any resources, such as counselling, during their clerkships. Narrative responses discussed significant effects on performing physical exams, taking a history, interacting with team members, and engaging during clerkships.

DISCUSSION

This work demonstrates the high number of students affected by SA/IPV and how these prior experiences affected core components of their clerkship experiences.

CONCLUSIONS

Institutions must be proactive to create better supports for learners with histories of trauma, including SA/IPV.

The Development of a Video Intervention to Improve Senior Medical Students' Performance on Outpatient Telephone Encounters: a Delphi Analysis and Randomized Controlled Trial

Introduction

Postgraduate trainees address outpatient telephone calls (OTCs) with little prior training. This study determines the skills necessary for OTCs and examines whether a video intervention improves medical students' performance on simulated OTCs.

Materials and Methods

We utilized a Delphi technique to determine skills needed for OTCs and created a 9-min video teaching these skills. Senior medical students were randomized to Intervention (viewed video) and Control (did not view video) groups. Students were assessed pre-/post-intervention on simulated OTCs. The primary outcome was the between-group difference in improvement.

Results

The Delphi yielded 34 important skills with the highest focus on communication (n = 13) and triage (n = 6). Seventy-two students completed assessments (Control, n = 41; Intervention, n = 31). The score (mean ± SD) improved 4.3% in the Control group (62.3 ± 14.3% to 66.6 ± 25.0%) and 12.2% in the Intervention group (60.7 ± 15.2% to 72.9 ± 20.4%, p = 0.15). The effect size measured by Cohen's d was 0.55, considered effective (> 0.33) for an educational intervention.

Conclusions

This project fills a gap in OTC training. The use of the Delphi technique, intervention development based on the results, and evaluation of efficacy is a process that could be reproduced for other educational gaps.

What Does "Patient-Centered" Mean? Qualitative Perspectives from Older Adults and Family Caregivers

This study aimed to (1) examine what patient-centeredness means for older adults and family caregivers, and (2) assess circumstances underlying their preference for geriatric care. We conducted separate focus groups with older adults and family caregivers of older adults about health care experiences and expectations and conducted a vignette-based experiment to assess preference for geriatric care. Participants expressed a need for greater skill and empathy and integration of caregivers. They preferred geriatric care to usual primary care with increasing social, health, and healthcare complexity. Distinct needs of older adults should be considered in referral practices to geriatric medicine.

Exploring How Personal, Social, and Institutional Characteristics Contribute to Geriatric Medicine Subspecialty Decisions: A Qualitative Study of Trainees' Perceptions

PURPOSE

To explore internal medicine residents' and geriatrics fellows' perceptions of how personal, social, and institutional characteristics contribute to their professional identity and subspecialty decisions related to geriatric medicine.

METHOD

The authors conducted 23 in-depth, semistructured interviews with internal medicine residents, with and without an interest in geriatrics, and geriatrics fellows across 3 academic medical centers in the United States from October 2018 through June 2019. They then used a qualitative narrative approach to analyze the interview data.

RESULTS

Trainees related personal experiences, such as exposure to physicians and experiences with grandparents, to their interest in medicine. Trainees with an interest in geriatrics at 2 institutions did not feel supported, or understood, by peers and mentors in their respective institutions but maintained their interest in the field. The following variations between institutions that are supportive and those that are not were noted: the number of geriatricians, the proximity of the institution to geriatrics clinics, and the ways in which institutional leaders portrayed the prestige of geriatric medicine. Institutional characteristics influenced trainees' understanding of what it meant to be a doctor, what meaning they garnered from work as a physician, and their comfort with different types of complexity, such as those presented when providing care to older adults.

CONCLUSIONS

Institutional characteristics may be particularly important in shaping trainee interest in geriatric medicine. Institutions should encourage leadership training and opportunities for geriatricians so they can serve as role models and as hands-on mentors for trainees beginning in medical school. Increasing the number of geriatricians requires institutions to increase the value they place on geriatrics to generate a positive interest in this field among trainees. Institutions facilitating formation of professional identity and sense of purpose in work may consider engaging geriatricians in leadership and mentoring roles as well as curriculum development.

Student Perceptions of educational handovers

BACKGROUND

Educational handovers can provide competency information about graduating medical students to residency program directors post-residency placement. Little is known about students' comfort with this novel communication.

OBJECTIVE

To examine graduated medical students' perceptions of educational handovers.

METHODS

The authors created and distributed an anonymous survey to 166 medical students at a single institution following graduation in the spring of 2018. Within this cohort, 40 students had an educational handover sent to their future program director. The survey explored comfort level with handovers (1=very uncomfortable; 5=very comfortable) and ideal content (e.g., student strengths, areas for improvement, goals, grades received after residency application). Respondents self-reported their performance in medical school and whether a handover was sent. Correlation analyses examined relationships between performance and other variables. T-tests examined differences between students who did and did not have a handover letter sent.

RESULTS

The survey response rate was 40.4% (67/166) - 47.8% of students felt comfortable with handovers, 19.4% were neutral, and 32.8% were uncomfortable. There was no correlation between self-reported medical school performance and comfort level. Respondents felt most strongly that strengths should be included, followed by goals. Those who had a handover letter sent expressed significantly higher comfort level (3.8 ± 1.0 vs. 2.6 ±1.3, p=0.003) with this communication.

CONCLUSION

Medical students reported varying levels of comfort with educational handovers; however, those who had handovers sent had more positive perceptions. In order to improve the education continuum, it is essential to engage students in the development of this handover communication.

Perceptions of Parenting Challenges and Career Progression Among Physician Faculty at an Academic Hospital

This survey study compares the perceptions of male and female physician faculty members who have children regarding parenting challenges and career progression at an academic hospital.

Eating Problems in Advanced Dementia: Navigating Difficult Conversations

INTRODUCTION

The majority of older adults with advanced dementia (AD) develop difficulties with eating and swallowing, often prompting concerns about nutrition and quality of life. Employing a palliative approach requires providers to attain skills in addressing symptoms and communicating with family caregivers about the trajectory of AD and associated dysphagia, as well as to elicit goals of care. Research suggests internal medicine (IM) residents often perceive minimal education during training addressing skills needed to care for patients with AD.

METHODS

We developed and piloted a small-group interactive seminar utilizing a trigger video depicting a family meeting addressing eating problems in a patient with AD. Case-based learning, small-group discussion, and learner reflection were employed. We assessed the impact on 82 of the 106 IM, medicine-pediatrics, and neurology residents who participated in the seminar.

RESULTS

Participant evaluation indicated residents showed high satisfaction and perceived the educational content of the seminar to be robust and clinically relevant. We found statistically significant (p < .001) improvements in self-reported confidence in dementia-specific skills postseminar. Effect size was large to very large (Cohen's d = 1.3-1.7).

DISCUSSION

An interactive, case-based seminar utilizing a video depicting a realistic family meeting improved residents' self-efficacy in skills needed to address nutritional issues, engage in goals-of-care discussions, and reflect on concerns among caregivers of patients with AD. The seminar teaches important geriatric and palliative concepts meant to improve residents' ability to care for older adults with AD in their future careers.

Internal medicine paging curriculum to improve physician-nurse interprofessional communication: a single center pilot study

Effective physician-nurse communication is critical to patient safety, yet internal medicine trainees are rarely given feedback on this skill. In order to address this gap, we developed a 4-week simulated paging curriculum for senior medical students. Standardized Registered Nurses administered five acute inpatient paging cases to students via telephone and scored communication on a 10-point global scale (1 = highly ineffective to 10 = highly effective) and seven communication domains using a 5-point Likert-type scale. The domains included precision/clarity, instructive, directing, assertive, ability to solicit information, engaged, and structured communication. Students received verbal and written feedback from the nurses on communication skills and clinical decision-making. Our primary goal was to determine if student-nurse communication improved throughout the curriculum. Data were analyzed using multivariate ANOVAs with repeated measures. Twenty-seven students participated. Global communication scores increased significantly from case 1 to case 5 (7.1 to 8.7, p < .01). The following communication domains increased significantly: precision (3.8 to 4.4, p < .01), instructive (3.6 to 4.7, p < .01), directing (4.0 to 4.6, p = .02), assertiveness (4.0 to 4.7, p = .04), engaged (4.1 to 4.7, p < .01). In conclusion, this curriculum can be an innovative approach to improve physician-nurse communication using standardized registered nurses to deliver structured feedback to medical trainees.

Does Performance on Evidence-Based Medicine and Urgent Clinical Scenarios Assessments Deteriorate During the Fourth Year of Medical School? Findings From One Institution

PURPOSE

The fourth year of medical school (M4) should prepare students for residency yet remains generally unstructured, with ill-defined goals. The primary aim of this study was to determine whether there were performance changes in evidence-based medicine (EBM) and urgent clinical scenarios (UCS) assessments before and after M4 year.

METHOD

University of Michigan Medical School graduates who matched into internship at Michigan Medicine completed identical assessments on EBM and UCS at the beginning of M4 year and 13 months later during postgraduate year 1 (PGY1) orientation. Individual scores on these assessments were compared using paired t test analysis. The associations of academic performance, residency specialty classification, and initial performance on knowledge changes were analyzed.

RESULTS

During academic years 2014 and 2015, 76 students matched into a Michigan Medicine internship; 52 completed identical EBM stations and 53 completed UCS stations. Learners' performance on the EBM assessment decreased from M4 to PGY1 (mean 93% [SD = 7%] vs. mean 80% [SD = 13%], P < .01), while performance on UCS remained stable (mean 80% [SD = 9%] vs. mean 82% [SD = 8%], P = .22). High M4 performers experienced a greater rate of decline in knowledge level compared with low M4 performers for EBM (-20% vs. -4%, P = .01). Residency specialty and academic performance did not affect performance.

CONCLUSIONS

This study demonstrated degradation of performance in EBM during the fourth year and adds to the growing literature that highlights the need for curricular reform during this year.

Are medical students trained in cross-cover?

OBJECTIVES

To examine the current state of cross-cover education in undergraduate medical education and intern perceived readiness to provide cross-cover.

METHODS

An electronic survey was distributed to 126 incoming interns in surgery, internal medicine, family medicine and paediatrics residencies at a single academic centre. Information regarding prior cross-cover training, experience, confidence, and responses to a sample cross-cover case were obtained.

RESULTS

The survey response rate was 69.8% (88 of 126), which included both partial and complete responses. Fifty-seven interns out of 85 (67.1%) had no formal training and 51 (60.0%) had no experience performing cross-cover. They reported feeling unprepared to provide cross-cover, with an average score of 1.8 on a 5-point Likert scale (1, not at all confident; 5, extremely confident). Interns had more confidence in performing cross-cover tasks if they had prior direct cross-cover experience (p = 0.001), and were the least confident in performing the initial evaluation and management of urgent issues (Likert score = 1.6). Scores on the sample case were correlated with the amount of prior experience with patients (p = 0.06). Only 77.7% of interns indicated that they would notify their senior resident in two urgent scenarios. Those who reported higher confidence in knowing when to ask for help were more likely to appropriately notify their senior colleague (p = 0.005). We identified gaps in cross-cover training and in the preparedness of incoming interns CONCLUSIONS: We identified gaps in cross-cover training and in the preparedness of incoming interns. This has important implications for the first day of residency, when interns are often asked to perform cross-coverage, yet feel unprepared to do so and express the greatest concern in urgent cross-cover scenarios. Addressing this curricular gap is crucial in assuring safe cross-cover care.

Zinc Acetate Lozenges May Improve the Recovery Rate of Common Cold Patients: An Individual Patient Data Meta-Analysis

Background

A previous meta-analysis of 3 zinc acetate lozenge trials estimated that colds were on average 40% shorter for the zinc groups. However, the duration of colds is a time outcome, and survival analysis may be a more informative approach. The objective of this individual patient data (IPD) meta-analysis was to estimate the effect of zinc acetate lozenges on the rate of recovery from colds.

Methods

We analyzed IPD for 3 randomized placebo-controlled trials in which 80–92 mg/day of elemental zinc were administered as zinc acetate lozenges to 199 common cold patients. We used mixed-effects Cox regression to estimate the effect of zinc.

Results

Patients administered zinc lozenges recovered faster by rate ratio 3.1 (95% confidence interval, 2.1–4.7). The effect was not modified by age, sex, race, allergy, smoking, or baseline common cold severity. On the 5th day, 70% of the zinc patients had recovered compared with 27% of the placebo patients. Accordingly, 2.6 times more patients were cured in the zinc group. The difference also corresponds to the number needed to treat of 2.3 on the 5th day. None of the studies observed serious adverse effects of zinc.

Conclusions

The 3-fold increase in the rate of recovery from the common cold is a clinically important effect. The optimal formulation of zinc lozenges and an ideal frequency of their administration should be examined. Given the evidence of efficacy, common cold patients may be instructed to try zinc acetate lozenges within 24 hours of onset of symptoms.

Zinc acetate lozenges for treating the common cold: an individual patient data meta-analysis

AIMS

The aim of this study was to determine whether the allergy status and other characteristics of common cold patients modify the effects of zinc acetate lozenges.

METHODS

We had available individual patient data for three randomized placebo-controlled trials in which zinc acetate lozenges were administered to common cold patients. We used both one stage and two stage meta-analysis to estimate the effects of zinc lozenges.

RESULTS

The total number of common cold patients was 199, the majority being females. Eighty percent of them fell into the age range 20-50 years. One third of the patients had allergies. The one stage meta-analysis gave an overall estimate of 2.73 days (95% CI 1.8, 3.3 days) shorter colds by zinc acetate lozenge usage. The two stage meta-analysis gave an estimate of 2.94 days (95% CI 2.1, 3.8 days) reduction in common cold duration. These estimates are to be compared with the 7 day average duration of colds in the three trials. The effect of zinc lozenges was not modified by allergy status, smoking, baseline severity of the common cold, age, gender or ethnic group.

CONCLUSION

Since the effects of zinc acetate lozenges were consistent between the compared subgroups, the overall estimates for effect seemed applicable over a wide range of common cold patients. While the optimal composition of zinc lozenges and the best frequency of their administration should be further investigated, given the current evidence of efficacy, common cold patients may be encouraged to try zinc lozenges for treating their colds.

Reported Exercise Patterns and their Relationship to Lipid Levels among Healthy Older Adults

There have been few studies concerning the relationship between exercise habits and lipid levels of older adults. This study examines this relationship using data from 117 healthy older adults who volunteered to participate in a health promotion project. Responses to a seven-day activity recall questionnaire, percentage of body fat as measured by bioelectric impedance, age, and gender were used to predict total cholesterol, HDL, LDL, and triglyceride levels. Only the model predicting HDL was significant (R2=. 15, p = .002). Subsequent regression analyses predicting HDL levels were limited to persons who participated in one or more exercise sessions in the previous week. For these active women, the model's ability to predict HDL improved (R2= .37,p = .005), with exercise level having the greatest effect. For the active men, the model's predictive ability was not significant. The findings suggest that for active women, level of physical activity does modestly influence HDL levels.

Attitudes of Employees for an On-Campus Health Promotion Program at a Large Urban University

This article describes the results of a survey among employees at Wayne State University that were designed to determine the desire for and willingness to participate in a campus wellness program. All 4,300 employees were mailed a questionnaire during the period March-June 1989. Among the 2,401 respondents (56% response rate), 81% felt a wellness program should be offered and 57% indicated an intention to participate. A significantly higherpercentage ofBlacks (77%) and women (62%) stated they would participate as compared to Whites (51%) and men (51%). There was an inverse relationship between desire for the program and income level; those who held commercial health club memberships and resided closerto campus showed higher interest. In the overall sample, lunchtime activities were the most requested. Types of services most requested included health screening (e.g., cholesterol testing and fitness assessment) and exercise classes.

A Preliminary Study of the Impact of Case Specificity on Computer-Based Assessment of Medical Student Clinical Performance

The implications of case specificity of two computer-based clinical simulation examination cases (CBX) were examined by a classical measurement approach and by a Bayesian analysis of test characteristics. The CBXs (a surgery and an ob/gyn case) were designed by the National Board of Medical Examiners and administered to 163 University of Michigan Medical School students. The results indicate that the students performed differently on the two cases, the surgery case appearing to be more difficult. The ob/gyn case had greater sensitivity (more accuracy in passing competent students), whereas the surgery case had greater specificity (more accuracy in failing noncompetent students). The differences between the cases and evidence of case specificity raise the issue of an exam's objective and the acceptable type of classification error These results suggest that additional studies are required before widespread use of such exams can be implemented in "high stakes" situations for licensure purposes.

Competency-based education: programme design and challenges to implementation

CONTEXT

Competency-based education (CBE) has been widely cited as an educational framework for medical students and residents, and provides a framework for designing educational programmes that reflect four critical features: a focus on outcomes, an emphasis on abilities, a reduction of emphasis on time-based training, and promotion of learner centredness. Each of these features has implications and potential challenges for implementing CBE.

METHODS

As an experiment in CBE programme design and implementation, the University of Michigan Master of Health Professions Education (UM-MHPE) degree programme was examined for lessons to be learned when putting CBE into practice. The UM-MHPE identifies 12 educational competencies and 20 educational entrustable professional activities (EPAs) that serve as the vehicle for both learning and assessment. The programme also defines distinct roles of faculty members as assessors, mentors and subject-matter experts focused on highly individualised learning plans adapted to each learner.

CONCLUSIONS

Early experience with implementing the UM-MHPE indicates that EPAs and competencies can provide a viable alternative to traditional courses and a vehicle for rigorous assessment. A high level of individualisation is feasible but carries with it significant costs and makes intentional community building essential. Most significantly, abandoning a time-based framework is a difficult innovation to implement in a university structure that is predicated on time-based education.

Assessment challenges in competency-based education: A case study in health professions education

There is a growing demand for health sciences faculty with formal training in education. Addressing this need, the University of Michigan Medical School created a Master in Health Professions Education (UM-MHPE). The UM-MHPE is a competency-based education (CBE) program targeting professionals. The program is individualized and adaptive to the learner's situation using personal mentoring. Critical to CBE is an assessment process that accurately and reliably determines a learner's competence in educational domains. The program's assessment method has two principal components: an independent assessment committee and a learner repository. Learners submit evidence of competence that is evaluated by three independent assessors. The assessments are presented to an Assessment Committee who determines whether the submission provides evidence of competence. The learner receives feedback on the submission and, if needed, the actions needed to reach competency. During the program's first year, six learners presented 10 submissions for review. Assessing learners in a competency-based program has created challenges; setting standards that are not readily quantifiable is difficult. However, we argue it is a more genuine form of assessment and that this process could be adapted for use within most competency-based formats. While our approach is demanding, we document practical learning outcomes that assess competence.

Validation of the Revised Brief Diabetes Knowledge Test (DKT2)

Purpose

The purpose of this study is to examine the reliability and validity of the revised Diabetes Knowledge Test (DKT2). The original test was updated to reflect current diabetes care and education guidelines. The test has 2 components: a 14-item general test and a 9-item insulin use subscale.

Methods

Two samples were used to evaluate the DKT2. The first came from an online survey company (Qualtrics, LCC) (n = 101) and the second from University of Michigan’s (UofM) Diabetes Registry (n = 89). Cronbach’s coefficient alpha was used to calculate reliability. To examine validity, comparisons by type of diabetes, insulin use and oral medication use, and educational level were completed. Correlations between diabetes duration and both the general test and insulin subscale were calculated for the UofM sample.

Results

The two samples differed demographically. While the reliabilities between the samples were disparate, when combined, the coefficient alphas demonstrated reliability for both the general test (.77) and the insulin use subscale (.84). The validation comparisons proved to be similar; different results occurred between samples but when combined demonstrated validity.

Conclusions

The reliability and validity tests were inconsistent by sample. The different results can, in part, be attributed to the demographic differences between the 2 samples. With the exception of age, the samples differed in every other measured variable. However, when the samples were combined, the analyses supported the reliability and validity of the Diabetes Knowledge Test 2. The DKT2 is a quick and low-cost method of assessing general knowledge of diabetes and diabetes self-care.

A targeted infection prevention intervention in nursing home residents with indwelling devices: a randomized clinical trial

IMPORTANCE

Indwelling devices (eg, urinary catheters and feeding tubes) are often used in nursing homes (NHs). Inadequate care of residents with these devices contributes to high rates of multidrug-resistant organisms (MDROs) and device-related infections in NHs.

OBJECTIVE

To test whether a multimodal targeted infection program (TIP) reduces the prevalence of MDROs and incident device-related infections.

DESIGN, SETTING, AND PARTICIPANTS

Randomized clinical trial at 12 community-based NHs from May 2010 to April 2013. Participants were high-risk NH residents with urinary catheters, feeding tubes, or both.

INTERVENTIONS

Multimodal, including preemptive barrier precautions, active surveillance for MDROs and infections, and NH staff education.

MAIN OUTCOMES AND MEASURES

The primary outcome was the prevalence density rate of MDROs, defined as the total number of MDROs isolated per visit averaged over the duration of a resident's participation. Secondary outcomes included new MDRO acquisitions and new clinically defined device-associated infections. Data were analyzed using a mixed-effects multilevel Poisson regression model (primary outcome) and a Cox proportional hazards model (secondary outcome), adjusting for facility-level clustering and resident-level variables.

RESULTS

In total, 418 NH residents with indwelling devices were enrolled, with 34,174 device-days and 6557 anatomic sites sampled. Intervention NHs had a decrease in the overall MDRO prevalence density (rate ratio, 0.77; 95% CI, 0.62-0.94). The rate of new methicillin-resistant Staphylococcus aureus acquisitions was lower in the intervention group than in the control group (rate ratio, 0.78; 95% CI, 0.64-0.96). Hazard ratios for the first and all (including recurrent) clinically defined catheter-associated urinary tract infections were 0.54 (95% CI, 0.30-0.97) and 0.69 (95% CI, 0.49-0.99), respectively, in the intervention group and the control group. There were no reductions in new vancomycin-resistant enterococci or resistant gram-negative bacilli acquisitions or in new feeding tube-associated pneumonias or skin and soft-tissue infections.

CONCLUSIONS AND RELEVANCE

Our multimodal TIP intervention reduced the overall MDRO prevalence density, new methicillin-resistant S aureus acquisitions, and clinically defined catheter-associated urinary tract infection rates in high-risk NH residents with indwelling devices. Further studies are needed to evaluate the cost-effectiveness of this approach as well as its effects on the reduction of MDRO transmission to other residents, on the environment, and on referring hospitals.

Medical school handoff education improves postgraduate trainee performance and confidence

OBJECTIVES

Determine postgraduate first-year (PGY-1) trainees ability to perform patient care handoffs and associated medical school training.

METHODS

About 173 incoming PGY-1 trainees completed an OSCE handoff station and a survey eliciting their training and confidence in conducting handoffs. Independent t-tests compared OSCE performance of trainees who reported receiving handoff training to those who had not. Analysis of variance examined differences in performance based on prior handoff instruction and across levels of self-assessed abilities, with significance set at p<0.05.

RESULTS

About 35% of trainees reported receiving instruction and 51% reported receiving feedback about their handoff performance in medical school. Mean handoff performance score was 69.5%. Trainees who received instruction or feedback during medical school had higher total and component handoff performance scores (p<0.05); they were also more confident in their handoff abilities (p<0.001). Trainees with higher self-assessed skills and preparedness performed better on the OSCE (p<0.05).

CONCLUSIONS

This study provides evidence that incoming trainees are not well prepared to perform handoffs. However, those who received instruction during medical school perform better and are more confident on standardized performance assessments. Given communication failures lead to uncertainty in patient care and increases in medical errors, medical schools should incorporate handoff training as required instruction.

Antibody to Epstein-Barr virus deoxyuridine triphosphate nucleotidohydrolase and deoxyribonucleotide polymerase in a chronic fatigue syndrome subset

BACKGROUND

A defined diagnostic panel differentiated patients who had been diagnosed with chronic fatigue syndrome (CFS), based upon Fukuda/Carruthers criteria. This diagnostic panel identified an Epstein-Barr virus (EBV) subset of patients (6), excluding for the first time other similar "clinical" conditions such as cytomegalovirus (CMV), human herpesvirus 6 (HHV6), babesiosis, ehrlichiosis, borreliosis, Mycoplasma pneumoniae, Chlamydia pneumoniae, and adult rheumatic fever, which may be mistakenly called CFS. CFS patients were treated with valacyclovir (14.3 mg/kg q6h) for ≥ 12 months. Each patient improved, based upon the Functional Activity Appraisal: Energy Index Score Healthcare Worker Assessment (EIPS), which is a validated (FSS-9), item scale with high degree of internal consistency measured by Cronbach's alpha.

METHODS

Antibody to EBV viral capsid antigen (VCA) IgM, EBV Diffuse Early Antigen EA(D), and neutralizing antibodies against EBV-encoded DNA polymerase and EBV-encoded dUTPase were assayed serially approximately every three months for 13-16 months from sera obtained from patients with CFS (6) and from sera obtained from twenty patients who had no history of CFS.

RESULTS

Antibodies to EBV EA(D) and neutralizing antibodies against the encoded-proteins EBV DNA polymerase and deoxyuridine triphosphate nucleotidohydrolase (dUTPase) were present in the EBV subset CFS patients. Of the sera samples obtained from patients with CFS 93.9% were positive for EA(D), while 31.6% of the control patients were positive for EBV EA(D). Serum samples were positive for neutralizing antibodies against the EBV-encoded dUTPase (23/52; 44.2%) and DNA polymerase (41/52; 78.8%) in EBV subset CFS patients, but negative in sera of controls.

CONCLUSIONS

There is prolonged elevated antibody level against the encoded proteins EBV dUTPase and EBV DNA polymerase in a subset of CFS patients, suggesting that this antibody panel could be used to identify these patients, if these preliminary findings are corroborated by studies with a larger number of EBV subset CFS patients.

Internal medicine house officers' attitudes and experience with patients who overstep patient-physician boundaries

Maintenance of appropriate social boundaries is an essential aspect of patient care. Given limited clinical experience, house officers may be especially vulnerable to such transgressions. We studied the frequency of patients' transgressions of boundaries and house officer responses to these transgressions. An online survey was administered to internal medicine house officers at the University of Michigan Health System that addressed the frequency of patient-physician boundary transgressions, house officer responses to transgressions, and the perceived need for education regarding transgressions. The frequency of reported patient transgressions of various boundaries during the past 6 months ranged from 0 to more than 30. The most common reported incident was being called by their first name, and the least common incidents included patients engaging/attempting to engage in sexual contact and attempting to give expensive gifts. Most respondents denied the need for education regarding appropriate boundaries with patients; however, most perceived a need for training on how to respond to transgressions. Overall, there was a wide range in reported frequencies of transgressions. The frequency of transgressions reported by house officers was greater than what is previously described for attending physicians though their responses to transgressions were similar.

Conceptual model for reducing infections and antimicrobial resistance in skilled nursing facilities: focusing on residents with indwelling devices

Infections in skilled nursing facilities (SNFs) are common and result in frequent hospital transfers, functional decline, and death. Colonization with multidrug-resistant organisms (MDROs) - including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and multidrug-resistant gram-negative bacilli (R-GNB) - is also increasingly prevalent in SNFs. Antimicrobial resistance among common bacteria can adversely affect clinical outcomes and increase health care costs. Recognizing a need for action, legislators, policy-makers, and consumer groups are advocating for surveillance cultures to identify asymptomatic patients with MDROs, particularly MRSA in hospitals and SNFs. Implementing this policy for all SNF residents may be costly, impractical, and ineffective. Such a policy may result in a large increase in the number of SNF residents placed in isolation precautions with the potential for reduced attention by health care workers, isolation, and functional decline. Detection of colonization and subsequent attempts to eradicate selected MDROs can also lead to more strains with drug resistance. We propose an alternative strategy that uses a focused multicomponent bundle approach that targets residents at a higher risk of colonization and infection with MDROs, specifically those who have an indwelling device. If this strategy is effective, similar strategies can be studied and implemented for other high-risk groups.

Geriatrics educational outreach: A tale of three GRECCS

Current geriatrics workforce projections indicate that clinicians who care for adults will need basic geriatrics knowledge and skills to address the geriatric syndromes and issues that limit functional independence and complicate medical management. This is most evident for the clinicians caring for veterans in the Department of Veterans Affairs hospitals and clinics nationwide. Geriatric Research, Education and Clinical Centers (GRECCs), whose staff are geriatric-content experts, have developed a number of programs to tackle this daunting educational task. This article introduces three different programs designed and implemented by GRECCs to train currently practicing health care providers in the Veterans Health Administration medical clinics. It also describes the successes and lessons learned from these three programs.

Perceptions and attitudes are primary contributors to insulin delivery system satisfaction in people with type 2 diabetes

BACKGROUND

This study identifies factors that influence satisfaction with an insulin delivery system (IDS). Knowledge of such factors could help identify individuals who would benefit from innovative IDS.

METHODS

Individuals with type 2 diabetes who use insulin, recruited from a general and chronic illness panel, participated in a web-based survey that included questions about demographics, self-reported diagnoses and hemoglobin A1c (HbA1c), current IDS used, insulin therapy attitudes, current IDS features, and satisfaction with IDS. Univariate analyses identified variables associated with IDS satisfaction (P < 0.05); those variables were entered into stepwise linear regression analyses with IDS satisfaction as the dependent variable.

RESULTS

Six hundred sixty-seven individuals with type 2 diabetes participated (mean age, 57 years; 52% female; 88% Caucasian; 73% vial/syringe users, 27% insulin pen users). IDS satisfaction was associated (P < 0.05) with gender, health status, HbA1c, self-reported comorbidity, insulin therapy attitudes, IDS type, and evaluation of IDS features. Among individuals who reported their HbA1c (n = 438), the best predictors of IDS satisfaction were perceived effectiveness and value of insulin therapy, evaluation of IDS activity interference, and commitment to insulin therapy (R2 = 0.49, P < 0.001). Among all participants (n = 667), a second regression analysis that employed a variable representing report of HbA1c found the best predictors of IDS satisfaction included those in the first analysis with the addition of gender, report of HbA1c, and evaluation of IDS ease of use. These variables provided additional variance (R2 = 0.56, P < 0.001).

CONCLUSIONS

In people with type 2 diabetes, positive perceptions and attitudes about insulin therapy have greater influence than the type of IDS used on IDS satisfaction.

Evaluating the Efficacy of an Empowerment-Based Self-Management Consultant Intervention: Results of a Two-Year Randomized Controlled Trial

OBJECTIVES: This study was conducted to determine if an empowerment-based Diabetes Self-Management Consultant (DSMC) was more effective than a group receiving Mailed metabolic Assessments Only (MAO) in improving diabetes-related quality of life and blood glucose control. MATERIALS AND METHODS: A two-year clinical trial, in which 310 patients with type 2 diabetes were randomized to the DSMC intervention or the MAO group. The DSMC met with the patient to review the baseline assessments, then met with this review was patient and the patient's physician. Subsequently patients received monthly telephone calls from the DSMC who used the empowerment approach to help patients identify self-management problems, consider options, set goals and make adjustments to their diabetes self-management plans. RESULTS: The Diabetes Self-Management Consultant (DSMC) intervention resulted in improvements in diabetes related quality of life (PAID) p= .008, the Empowerment Scale p= .024, A1C p= .016, Perceived understanding of diabetes p= .001 and satisfaction with diabetes care p= .019 as compared to the MAO group. DISCUSSION/CONCLUSION: The DSMC the intervention resulted in a broad array of modest diabetes related improvements. A promising area for future research would be to test the efficacy of combining an empowerment-based DSMC intervention with case management using algorithm-based medication adjustments for higher risk patients.

Validation of the energy index point score to serially measure the degree of disability in patients with chronic fatigue syndrome

BACKGROUND

A simple quantitative accurate method for assessing the degree of fatigue in patients with chronic fatigue syndrome (CFS) is necessary for physicians and patients. Severity of the disease and recovery can, thus, be assayed.

PATIENT AND METHODS

From February 1-27, 2007, fifty-six consecutive CFS patients at a single treatment center were simultaneously evaluated by the patient with the fatigue severity score (FSS), and by consensus of both patient and physician by the energy index (EI) point score.

RESULTS

The FSS and EI correlated well, 0.67, p<0.001.

CONCLUSION

The El point score is a validated reliable method to assess fatigue in CFS patients.

Zinc supplementation decreases oxidative stress, incidence of infection, and generation of inflammatory cytokines in sickle cell disease patients

Zinc deficiency is common in adult sickle-cell disease (SCD) patients. We previously demonstrated that zinc supplementation to adult SCD patients decreased the incidences of infections and hospital admissions. We hypothesize that zinc supplementation improves T-helper cell function and decreases vascular endothelial cell activation, oxidative stress, and nuclear factor-kappa B (NF-kappaB)-DNA binding in mononuclear cells (MNCs) in SCD patients. To test this hypothesis, 36 SCD patients were recruited and randomly divided into 2 groups. One group (n = 18) received 25-mg zinc orally thrice a day for 3 months. The other group (n = 18) received placebo. The results indicate that the zinc-supplemented group had decreased incidence of infections compared with the placebo group. After zinc supplementation, red blood cell, hemoglobin (Hb), hematocrit, (Hct), plasma zinc, and antioxidant power increased; plasma nitrite and nitrate (NOx), lipid peroxidation products, DNA oxidation products, and soluble vascular cell adhesion molecule-1 decreased in the zinc-supplemented group, compared with the placebo group. Zinc-supplemented patients exhibited significant decreases in lipopolysaccharide-induced tumor necrosis factor-alpha (TNF-alpha) and IL-1beta mRNAs, and TNF-induced nuclear factor of kappaB-DNA binding in MNCs, compared with the placebo group. Ex vivo addition of zinc to MNCs isolated from the placebo subjects decreased TNF-alpha and IL-1beta mRNAs. Zinc supplementation also increased relative levels of IL-2 and IL-2Ralpha mRNAs in phytohemagglutinin-p-stimulated MNCs. These results suggest that zinc supplementation may be beneficial to SCD patients.

Duration and severity of symptoms and levels of plasma interleukin-1 receptor antagonist, soluble tumor necrosis factor receptor, and adhesion molecules in patients with common cold treated with zinc acetate

BACKGROUND

Zinc lozenges have been used for treatment of the common cold; however, the results remain controversial.

METHODS

Fifty ambulatory volunteers were recruited within 24 h of developing symptoms of the common cold for a randomized, double-blind, placebo-controlled trial of zinc. Participants took 1 lozenge containing 13.3 mg of zinc (as zinc acetate) or placebo every 2-3 h while awake. The subjective scores for common cold symptoms were recorded daily. Plasma zinc, soluble interleukin (IL)-1 receptor antagonist (sIL-1ra), soluble tumor necrosis factor receptor 1, soluble vascular endothelial cell adhesion molecule, and soluble intercellular adhesion molecule (sICAM)-1 were assayed on days 1 and 5.

RESULTS

Compared with the placebo group, the zinc group had a shorter mean overall duration of cold (4.0 vs. 7.1 days; P < .0001) and shorter durations of cough (2.1 vs. 5.0 days; P < .0001) and nasal discharge (3.0 vs. 4.5 days, P = .02) Blinding of subjects was adequate, and adverse effects were comparable in the 2 groups. Symptom severity scores were decreased significantly in the zinc group. Mean changes in plasma levels of zinc, sIL-1ra, and ICAM-1 differed significantly between groups.

CONCLUSION

Administration of zinc lozenges was associated with reduced duration and severity of cold symptoms. We related the improvement in cold symptoms to the antioxidant and anti-inflammatory properties of zinc.

Primary care physician beliefs about insulin initiation in patients with type 2 diabetes

BACKGROUND

Insulin is the most effective drug available to achieve glycaemic goals in patients with type 2 diabetes. Yet, there is reluctance among physicians, specifically primary care physicians (PCPs) in the USA, to initiate insulin therapy in these patients.

AIMS

To describe PCPs' attitudes about the initiation of insulin in patients with type 2 diabetes and identify areas in which there is a clear lack of consensus.

METHODS

Primary care physicians practicing in the USA, seeing 10 or more patients with type 2 diabetes per week, and having > 3 years of clinical practice were surveyed via an internet site. The survey was developed through literature review, qualitative study and expert panel.

RESULTS

Primary care physicians (n = 505, mean age = 46 years, 81% male, 62% with > 10 years practice; 52% internal medicine) showed greatest consensus on attitudes regarding risk/benefits of insulin therapy, positive experiences of patients on insulin and patient fears or concerns about initiating insulin. Clear lack of consensus was seen in attitudes about the metabolic effects of insulin, need for insulin therapy, adequacy of self-monitoring blood glucose, time needed for training and potential for hypoglycaemia in elderly patients.

CONCLUSIONS

The beliefs of some PCPs are inconsistent with their diabetes treatment goals (HbA1c < or = 7%). Continuing medical education programmes that focus on increasing primary care physician knowledge about the progression of diabetes, the physiological effects of insulin, and tools for successfully initiating insulin in patients with type 2 diabetes are needed.

Patient-provider perceptions of diabetes and its impact on self-management: a comparison of African-American and White patients

AIMS

To compare patient-provider differences in diabetes-related perceptions between African-American and White patients and to examine its association with self-care behaviours.

METHODS

One hundred and thirty patient-provider pairs were recruited from the greater Detroit area. Patients and providers completed a survey assessing perceptions about diabetes-related concepts and demographic background. The Diabetes Semantic Differential Scale was used to measure diabetes-related perceptions. Patients also reported the frequency of performing self-care behaviours, including following a healthy eating plan, engaging in physical activity, blood glucose monitoring, and taking medication and/or insulin.

RESULTS

There were a greater number of patient-provider differences in diabetes-related perceptions for the African-American patients (nine of 18 concepts) compared with the White patients (four of 18 concepts). Stepwise regression analyses found patients' semantic differential scores to be significantly associated with five self-care behaviours for African-American patients and two self-care behaviours for White patients. Providers' semantic differential scores emerged as predictors of self-care behaviours for African-American patients, but not for White patients.

CONCLUSIONS

Our findings suggest that compared with White patients, African-Americans differ in a greater number of diabetes-related perceptions than their providers. Patients' and providers' perceptions of diabetes care concepts have a significant impact on a greater number of self-care behaviours for African-American patients than White patients.

Patient and provider perceptions of diabetes: measuring and evaluating differences

OBJECTIVE

This study measures diabetes care perceptions of patients and their providers, and examines perceptions differences of patient-provider pairs.

METHODS

Patient and provider perceptions were assessed using the Diabetes Semantic Differential Scales (DSDS) which ask respondents to rate diabetes care concepts using contrasting adjective pairs. The DSDS was scored by two methods: using means and using factor analysis. Persons with diabetes 40-years-old or older were recruited. Using a "snowball" sampling strategy, potential provider participants were identified by their patients; 71 providers agreed. These providers represented 51% of the patient participants and created 138 patient-provider pairs.

RESULTS

For the mean scores, there were significant differences between patients and providers for 5 of the 18 semantic differentials (28%). Similarly, the factor scores indicated significant differences for 14 of 54 factors (26%). The effect sizes indicated practical differences.

CONCLUSION

Significant differences exist between patient and provider perceptions. Generally, patients have the more positive diabetes perceptions.

PRACTICE IMPLICATIONS

During patient and provider discussions, participants can perceive diabetes concepts differently. The DSDS can determine perception differences. While it is best to use factor analyses to score the DSDS, mean scores are more easily calculated and indicate the broad conceptual areas where patient and provider differ.

Successful implementation of a faculty development program in geriatrics for non-primary care physician educators

A four-year faculty development program to enhance geriatrics learning among house officers in seven surgical and related disciplines and five medical subspecialties at a large academic institution resulted in changes in attitudes and knowledge of faculty participants, expanded curricula and teaching activities in geriatrics, and enhanced and altered career trajectories of faculty participants. The program centered on problem-oriented longitudinal small group seminars with concurrent application of new skills. Key success factors included securing the active support of institutional leaders, focus on career development, examining presumptions regarding professional scope, protected time for faculty participants, and provision of teaching and evaluation resources for individualized application by faculty.

Immunoassay with cytomegalovirus early antigens from gene products p52 and CM2 (UL44 and UL57) detects active infection in patients with chronic fatigue syndrome

AIMS

To investigate whether the use of recombinant early antigens for detection of antibodies to human cytomegalovirus (HCMV) gene products CM(2) (UL44, UL57) and p52 (UL44) is specific in the diagnosis and differentiation of active HCMV infection in a subset of patients with chronic fatigue syndrome (CFS), a diagnosis which is often missed by the current ELISA assay that uses crude viral lysate antigen.

METHODS

At a single clinic from 1999 to 2001, a total of 4774 serological tests were performed in 1135 patients with patients using two immunoassays, Copalis and ELISA. The Copalis immunoassay utilised HCMV early gene products of UL44 and UL57 recombinant antigens for detection of HCMV IgM antibody, and viral capsid antigen for detection of HCMV IgG antibody. The ELISA immunoassay utilised viral crude lysate as antigen for detection of both HCMV IgG and IgM.

RESULTS

517 patients (45.6%) were positive for HCMV IgG by both assays. Of these, 12 (2.2%) were positive for HCMV(V) IgM serum antibody by HCMV ELISA assay, and 61 (11.8%) were positive for IgM HCMV serum antibody by Copalis assay. The Copalis assay that uses HCMV early recombinant gene products CM(2) (UL44, UL57) and p52 (UL44) in comparison with ELISA was 98% specific.

CONCLUSIONS

Immunoassays that use early antigen recombinant HCMV CM(2) and p52 are five times more sensitive than HCMV ELISA assay using viral lysate, and are specific in the detection and differentiation of active HCMV infection in a subset of patients with CFS.

A Vertically Integrated Geriatric Curriculum Improves Medical Student Knowledge and Clinical Skills

The objective of this study was to determine the effect of a vertically integrated curriculum intervention on the geriatric knowledge and performance in clinical skills of third-year medical students. This observational cohort study conducted at the University of Michigan Medical School evaluates the performance of 622 third-year medical students from the graduating class years of 2004 through 2007. An integrated curriculum intervention was developed and implemented for the class of 2006. Its elements included identification and tracking of geriatric learning outcomes in an individualized Web-based student portfolio, integration of geriatric content into preclinical courses, development of a geriatric functional assessment standardized patient instructor, and an experience in a geriatrics clinic during the ambulatory component of the third-year internal medicine clerkship. Medical student performance was assessed on a geriatric knowledge test and during a geriatric functional assessment station administered during an Observed Structured Clinical Examination (OSCE) at the beginning of the fourth year. Student performance on the geriatric functional assessment OSCE station progressively improved from pre-intervention performance (mean performance+/-standard deviation 43+/-15% class of 2005, 62 + 15% class of 2006, 78+/-10% class of 2007; analysis of variance, P<.001). Similarly, student performance on the geriatric knowledge test was significantly better for the classes of 2006 and 2007 than for the class of 2005 (model F ratio=4.72; P<.001). In conclusion, an integrated approach to incorporating new educational geriatric objectives into the medical school curriculum leads to significant improvements in medical student knowledge and in important clinical skills in the functional assessment of older patients.

Valacyclovir treatment in Epstein-Barr virus subset chronic fatigue syndrome: thirty-six months follow-up

We hypothesized that subset classification of Epstein-Barr virus (EBV) in chronic fatigue syndrome (CFS) is required. At first, a blinded-random placebo-controlled trial of valacyclovir in EBV CFS subset was performed (Group 1), and this EBV subset was followed for thirty-six months (Group 2). Patients were given valacyclovir at 14.3 mg/kg every 6 hours. The validated Energy Index (EI) point score assessing physical functional capacity, Holter monitor, multigated (radionuclide) MUGA rest/stress ventriculographic examination, EBV serum IgM viral capsid antibodies (VCA), and EBV early antigen diffuse (EA) were followed. After six-months, Group 1 CFS patients receiving valacyclovir experienced an increased mean least square EI point score +1.12 units (122 kcal/day), while the placebo cohort increased +0.42 EI units (65 kcal/day). EI point scores at Group 2 increased progressively. Sinus tachycardias decreased and abnormal cardiac wall motion improved. Serum antibody titers to EBV VCA IgM decreased. Patients resumed normal activities.

Zinc supplementation decreases incidence of infections in the elderly: effect of zinc on generation of cytokines and oxidative stress

BACKGROUND

Zinc deficiency, cell-mediated immune dysfunction, susceptibility to infections, and increased oxidative stress have been observed in elderly subjects (ie, those >55 y old). Zinc is an effective antiinflammatory and antioxidant agent.

OBJECTIVES

The primary objective was to determine the effect of zinc on the incidence of total infections in healthy elderly subjects. The secondary objective was to determine the effect of zinc on cytokines and oxidative stress markers.

DESIGN

A randomized, double-blind, placebo-controlled trial of zinc supplementation was conducted in elderly subjects. Fifty healthy subjects of both sexes aged 55-87 y and inclusive of all ethnic groups were recruited for this study from a senior center. The zinc-supplemented group received zinc gluconate (45 mg elemental Zn/d) orally for 12 mo. Incidence of infections during the supplementation period was documented. The generation of inflammatory cytokines, T helper 1 and T helper 2 cytokines, and oxidative stress markers and the plasma concentrations of zinc were measured at baseline and after supplementation.

RESULTS

Compared with a group of younger adults, at baseline the older subjects had significantly lower plasma zinc, higher ex vivo generation of inflammatory cytokines and interleukin 10, and higher plasma oxidative stress markers and endothelial cell adhesion molecules. The incidence of infections and ex vivo generation of tumor necrosis factor alpha and plasma oxidative stress markers were significantly lower in the zinc-supplemented than in the placebo group. Plasma zinc and phytohemagglutin-induced interleukin 2 mRNA in isolated mononuclear cells were significantly higher in the zinc-supplemented than in the placebo group.

CONCLUSIONS

After zinc supplementation, the incidence of infections was significantly lower, plasma zinc was significantly higher, and generation of tumor necrosis factor alpha and oxidative stress markers was significantly lower in the zinc-supplemented than in the placebo group.

Contrast-Enhanced CT Accurately Detects Hemorrhage in Torso Trauma: Direct Comparison With Angiography

OBJECTIVE

To assess the ability of contrast enhanced computed tomography (CECT) to detect active hemorrhage and other vascular injuries in chest, abdominal, and pelvic trauma patients, using angiographic findings and need for intervention as paired gold standards.

METHODS

We obtained approval from the Institutional review board for a retrospective search of the radiology information system: seeking trauma patients undergoing angiography within 24 hours of CECT for chest, abdominal, or pelvic injuries. CECT protocol was standard trauma CT, not specialized for CT angiography. Angiographic techniques varied with indication. Clinical and imaging reports and selected radiologic studies were reviewed, but the original dictated report was the interpretive standard. We used Fisher's exact test for statistical analysis.

RESULTS

During the 30-month study period, 466 patients underwent emergent interventional radiologic procedures. Of those, 418 were excluded for nontrauma indications or neuroangiographic procedures. Fourty-eight patients (33 male, 15 female, average age 43.4) thus constituted the study population in whom we evaluated 63 traumatic injuries. CT findings had statistically significant associations (p < 0.0001) with both angiographic evidence of active hemorrhage and the need for intervention, which were tabulated separately. CT had 94.1% sensitivity and 97.6% negative predictive value (NPV) for detection of active hemorrhage, and 92.6% sensitivity and 91.2% NPV for predicting need for surgical or endovascular intervention.

CONCLUSIONS

CECT findings correlate strongly with angiographic findings, though sensitivity remains imperfect. However, when CT is used in the context of other clinical features, particularly hemodynamic instability, it may enable clinicians to reserve emergent angiography for those patients in whom emergent intervention is planned.

Development of a Standardized Patient Instructor to Teach Functional Assessment and Communication Skills to Medical Students and House Officers

Professional societies have called for increased geriatrics training for all medical students and physicians. A Geriatrics Standardized Patient Instructor (GSPI) was developed in which learners assess the functional status of a patient preparing for hospital discharge. Standardized patients (SPs) rate learners on functional assessment and communication skills, and provide feedback. Seventeen SPs were trained. Correlations of ratings by SPs with ratings by three geriatricians of videotaped encounters indicated good reliability (correlation coefficient = 0.69 and 0.70 for functional assessment and communication skills, respectively). Results from two learner groups illustrated the utility and feasibility of the GSPI. First, 138 house officers in nine specialties experienced the GSPI as a formative evaluation during implementation of new geriatrics curricula. Mean scores+/-standard deviation (on a 100-point scale) for functional assessment and communication skills were 78+/-16 and 86+/-11, respectively. House officers rated the overall experience positively (mean rating (1 = poor, 5 = excellent) 3.9+/-0.8). Second, 171 first-year medical students (M1 s) encountered the GSPI as part of an intense, multimodal educational intervention. Mean scores on functional assessment and communication skills were 93+/-10 and 93+/-7, respectively. Mean overall rating of the experience by M1 s was 4.1+/-0.8. After demonstrated success as a teaching tool in these two groups of learners, the GSPI has been successfully used with second- and third-year (M3) medical students and house officers from a total of 12 specialties and incorporated into multistation Objective Standardized Clinical Examination exercises for incoming house officers and M3 s. Unlike existing diagnosis-oriented SPs, the GSPI can be used to assess and teach geriatrics skills to physician learners across disciplines and levels of training.

A study of certified diabetes educators: influences and barriers

PURPOSE

There were 2 related goals for this study. The first purpose was to describe the structure (type, staffing, and number of educational sessions provided), process (preferred learning approaches), and outcome measures commonly used to provide patient education. The second purpose was to identify the influences, resources, and constraints that affect and alter the attitudes and practices of diabetes educators.

METHODS

A 30-item questionnaire that addressed 4 areas--demographics, practice characteristics, education program structure, and educational processes--was mailed to a sample of American Association of Diabetes Educators members. Three hundred sixty-one registered nurse and registered dietician certified diabetes educators completed the questionnaire and were included in the final analysis.

RESULTS

This survey indicated that this group of certified diabetes educators has incorporated new research findings and innovative teaching methods into their practices. They experience few barriers and tend to make changes in their attitudes and practices based on scientific and experiential evidence. The 3 most highly rated influences on these changes were related to patient responses to their teaching, followed by continuing education conferences and new research findings.

CONCLUSIONS

Based on these findings, providing continuing education that first and foremost incorporates experience-based examples of effective strategies supported by research published in professional journals appears to have the most influence on the practice of educators.

Brief report: Brief instrument to assess geriatrics knowledge of surgical and medical subspecialty house officers

PROBLEM

Initiatives are underway to increase geriatrics training in nonprimary care disciplines. However, no validated instrument exists to measure geriatrics knowledge of house officers in surgical specialties and medical subspecialties.

METHODS

A 23-item multiple-choice test emphasizing inpatient care and common geriatric syndromes was developed through expert panels and pilot testing, and administered to 305 residents and fellows at 4 institutions in surgical disciplines (25% of respondents), emergency medicine (29%), medicine subspecialties (19%), internal medicine (12%), and other disciplines (15%).

RESULTS

Three items decreased internal reliability. The remaining 20 items covered 17 topic areas. Residents averaged 62% correct on the test. Internal consistency was appropriate (Cronbach's alpha coefficient=0.60). Validity was supported by the use of expert panels to develop content, and by overall differences in scores by level of training (P<.0001) and graded improvement in test performance, with 58%, 63%, 62%, and 69% correct responses among HO1, HO2, HO3, and HO4s, respectively.

CONCLUSIONS

This reliable, valid measure of clinical geriatrics knowledge can be used by a wide variety of surgical and medical graduate medical education programs to guide curriculum reform or evaluate program performance to meet certification requirements. The instrument is now available on the web.

Effects of a geriatrics interdisciplinary experience on learners' knowledge and attitudes

This study examines the impact of an interdisciplinary training program on knowledge and attitudes of learners from four health care programs: medicine, pharmacy, social work, and nursing. Sixty-two learners participated in a 4-day educational program (one day each week for 4 weeks) focusing on interdisciplinary geriatric care. After completing the program, learner scores improved on a knowledge test and two attitudinal subscales, and they reported a positive training experience. A short-term interdisciplinary educational intervention can have an impact on learners' knowledge of and attitudes toward older adults, and improve their understanding and confidence in participating in an interdisciplinary collaborative care team.

Barriers to following dietary recommendations in Type 2 diabetes

AIMS

To evaluate barriers to following dietary recommendations in patients with Type 2 diabetes.

METHODS

We conducted focus groups and surveys in urban and suburban VA and academic medical centres. For the written survey, a self-administered questionnaire was mailed to a random sample of 446 patients with diabetes. For the focus groups, six groups of patients with diabetes (three urban, three suburban) were conducted, with 6-12 participants in each group. The focus groups explored barriers across various types of diabetes self-management; we extracted all comments relevant to barriers that limited patients' ability to follow a recommended diet.

RESULTS

The written survey measured the burden of diabetes therapies (on a seven-point rating scale). Moderate diet was seen as a greater burden than oral agents (median 1 vs. 0, P = 0.001), but less of a burden than insulin (median 1 vs. 4, P < 0.001). A strict diet aimed at weight loss was rated as being similarly burdensome to insulin (median 4 vs. 4, P = NS). Despite this, self-reported adherence was much higher for both pills and insulin than it was for a moderate diet. In the focus groups, the most commonly identified barrier was the cost (14/14 reviews), followed by small portion sizes (13/14 reviews), support and family issues (13/14 reviews), and quality of life and lifestyle issues (12/14 reviews). Patients in the urban site, who were predominantly African-American, noted greater difficulties communicating with their provider about diet and social circumstances, and also that the rigid schedule of a diabetes diet was problematic.

CONCLUSIONS

Barriers to adherence to dietary therapies are numerous, but some, such as cost, and in the urban setting, communication with providers, are potentially remediable. Interventions aimed at improving patients' ability to modify their diet need to specifically address these areas. Furthermore, treatment guidelines need to consider patients' preferences and barriers when setting goals for treatment.

Development and utilization of vignettes in assessing medical students' support of older and younger patients' medical decisions

Currently no appropriate vignettes exist to examine issues of age-based care among students early in their medical careers. This paper addresses that issue in two parts. First, as the development of vignettes, widely used in medical research, is rarely described, suggestions for developing reliable and valid vignettes are presented. These suggestions are derived from the development of a series of vignettes assessing the support of older and younger patients' medical decisions among first year medical students. Second, the responses to the vignettes were analyzed quantitatively and qualitatively to assess potential age-based biases. Results indicate that students do not differ in their level of support for older and younger patients' medical decisions. However, students are more supportive of patients who desired aggressive treatments than of those who wished to end treatment. Many students did not focus on the age of the patient, but instead on the patient's quality of life.

Prevalence of abnormal cardiac wall motion in the cardiomyopathy associated with incomplete multiplication of Epstein-barr Virus and/or cytomegalovirus in patients with chronic fatigue syndrome

We reported unique incomplete herpesvirus (Epstein-Barr Virus (EBV) and/or nonstructural (HCMV) cytomegalovirus) multiplication in 2 distinct subsets of CFS patients. The CFS subsets were identified by: a) presence of IgM serum antibodies to HCMV nonstructural gene products p52 and CM2 (UL44 and UL57), and/or b) IgM serum antibodies to Epstein-Barr virus viral capsid antigen (EBV, VCA IgM). Diagnostic IgM serum antibodies were found in two independent blinded studies involving 49 CFS patients, but the same antibodies were absent in 170 control patients (p<0.05). Abnormal 24 Hr-electrocardiographic monitoring, tachycardias at rest and, in severe chronic cases, abnormal cardiac wall motion (ACWM) were seen in these same CFS patients. We now report a prospective consecutive case control study from 1987--1999 of cardiac dynamics as measured by radionuclide ventriculography in 98 CFS patients from 1987--1999. Controls were patients with various malignancies who were evaluated in protocols requiring radionuclide ventriculography before initiation of cardiotoxic chemotherapeutic agents. The prevalence of abnormal cardiac wall motion (ACWM) at rest in CFS patients was 10 out of 87 patients (11.5%). With stress exercise, 21 patients (24.1%) demonstrated ACWM. Cardiac biopsies in 3 of these CFS patients with ACWM showed a cardiomyopathy. Among the controls, ACWM at rest was present in 4 out of 191 patients (2%) (p=0.0018). A progressive cardiomyopathy caused by incomplete virus multiplication of EBV and/or HCMV in CFS patients is present.

Case management for patients with poorly controlled diabetes: a randomized trial

PURPOSE

To evaluate the effects of a collaborative case management intervention for patients with poorly controlled type 2 diabetes on glycemic control, intermediate cardiovascular outcomes, satisfaction with care, and resource utilization.

METHODS

We conducted a randomized controlled trial at two Department of Veterans Affairs Medical Centers involving 246 veterans with diabetes and baseline hemoglobin A(1C) (HbA(1C)) levels >or=7.5%. Two nurse practitioner case managers worked with patients and their primary care providers, monitoring and coordinating care for the intervention group for 18 months through the use of telephone contacts, collaborative goal setting, and treatment algorithms. Control patients received educational materials and usual care from their primary care providers.

RESULTS

At the conclusion of the study, both case management and control patients remained under poor glycemic control and there was little difference between groups in mean exit HbA(1C) level (9.3% vs. 9.2%; difference = 0.1%; 95% confidence interval: -0.4% to 0.7%; P = 0.65). There was also no evidence that the intervention resulted in improvements in low-density lipoprotein cholesterol level or blood pressure control or greater intensification in medication therapy. However, intervention patients were substantially more satisfied with their diabetes care, with 82% rating their providers as better than average compared with 64% of patients in the control group (P = 0.04).

CONCLUSION

An intervention of collaborative case management did not improve key physiologic outcomes for high-risk patients with type 2 diabetes. The type of patients targeted for intervention, organizational factors, and program structure are likely critical determinants of the effectiveness of case management. Health systems must understand the potential limitations before expending substantial resources on case management, as the expected improvements in outcomes and downstream cost savings may not always be realized.

Informal diabetes education: impact on self-management and blood glucose control

PURPOSE

The purpose of this study was to determine if participation in screening clinics to detect and treat diabetes-related eye disease also led to informal patient learning that had an impact on self-management behavior and blood glucose control.

METHODS

To evaluate the evidence for patient learning over time, the data of patients who returned as advised for 2 subsequent annual diabetes disease screenings were analyzed. Evaluation measures included medication use, self-management behavior, and hemoglobin A1c (A1C).

RESULTS

During the 2-year study period, the use of insulin increased by 37% at the first exam, 43% at the second exam, and 42% at the third exam (P = .02). No significant changes were found in the use of oral medication. Glucose self-monitoring also increased by 61% at the first exam, 71% at the second exam, and 76% at the third exam (P < .01). Mean A1C values for returning participants declined by 9.2% at the first exam, 8.9% at the second exam, and 8.6% at the third exam (P = .03).

CONCLUSIONS

The screening clinics had an educational impact associated with behavior change (improved self-management and glucose control) even though the clinics were not intended to produce such change. Therefore, caregivers should consider that patient learning can and should be part of every diabetes care encounter.
