Sexual history inquiry and HIV counseling: improving clinical skills and medical knowledge through an interactive workshop utilizing standardized patients.

BACKGROUND: Sexual history and HIV counseling (SHHIVC) are essential clinical skills. Our project's purpose was to evaluate a standardized patient educational intervention teaching third-year medical students SHHIVC. METHODS: A four-hour standardized patient workshop was delivered to one-half of the class each of three consecutive years at one medical school. Approximately 3.5 weeks later, all students engaged in a standardized patient examination including one station assessing SHHIVC, answered an open-ended written exercise following the standardized patient encounter, and completed a written examination including sexual history and HIV-related questions. RESULTS: Workshop participants scored higher than non-participants on SHHIVC items on the standardized patient station (P < .0001), written exam (P < .0001), and open-ended written exercise after the standardized patient encounter (P = .024). CONCLUSIONS: Our SHHIVC curriculum was associated with students demonstrating better clinical skills on a SHHIVC standardized patient examination station and more SHHIVC knowledge on two measures of medical knowledge than students not participating in the SHHIVC educational intervention.

Therapeutic monitoring of clozapine in Australia: the need for consensus.

In the absence of well-defined guidelines for the monitoring of plasma concentrations of clozapine, this study examined the practices of seven laboratories from four states in Australia. Laboratories analyzed 5 freeze-dried serum samples containing a mixture of clozapine and norclozapine in varying concentrations and the measurement data were analyzed for accuracy and precision. Additional information on laboratory practices was obtained through questionnaire responses. Measurement precision amongst the laboratories was good but there were significant differences in the accuracy of measurements from one laboratory. There were differences in the ranges for which assays had been validated and in suggested therapeutic ranges. These differences could have a significant impact on the interpretation of measured concentrations and patient care, and emphasize the need for consensus in this area. Repeat concentration measurements are recommended in the case of drug concentration measurements that are inconsistent with clinical observations or previous measurements.

The Kentucky medical curriculum: continuing innovations in educating physicians.

The University of Kentucky College of Medicine (UKCOM) retains a long history of educational commitment, quality, and innovation. Since undergoing a major curricular revision in the early 1990s, the evolving UKCOM curriculum has continued to incorporate advances in biomedical knowledge and pedagogy while meeting changing societal needs and expectations for physicians in practice. Building upon its established record of excellence in medical education, a curricular quality assurance (QA) program has been initiated to more efficiently guide improvement and innovation by providing faculty with key resources to identify and disseminate local best practices in teaching, learning, and evaluation. Through such efforts, the University of Kentucky College of Medicine is committed to providing a rich educational experience that will meet the needs of students, physicians, and patients well into the 21st century.

Proficiency testing (external quality assessment) of drug detection in oral fluid.

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall "present"/"not found" reports calculated as true positives/(true positives+false negatives) were for the amphetamine specific assay 50%, methyl-amphetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.

CPAP compliance: video education may help!

BACKGROUND: CPAP remains the treatment of choice for Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS), but compliance with CPAP is poor. Of many interventions tried to improve CPAP compliance, only education and humidification have been shown to be of benefit. Our purpose was to develop and pilot test a video to enhance patient understanding of obstructive sleep apnea and of the purpose, logistics, and benefits of CPAP use in patients newly diagnosed with OSAHS. A patient's CPAP compliance in the first few weeks after starting its use is predictive of long-term compliance with CPAP treatment. It is imperative that patients grasp at the outset both the severity of OSAHS and the effectiveness of CPAP therapy. METHODS: An educational video script was written based on recommendations for patient educational video materials and covering identified misconceptions about OSAHS and perceived barriers to CPAP use. The videotape is 15 min in length and features two middle-aged males, one African-American and one Euro-American, discussing OSAHS and CPAP in a factory break room. RESULTS: In a randomized two-group design with a control group, patients with newly diagnosed OSAHS, and who viewed the CPAP educational video on their first clinic, were significantly more likely to use their machine and to return for a 1-month clinic visit than were those in the control group. CONCLUSION: Viewing of a patient education video at the initial visit was found to significantly improve the rate of return for the follow-up visit.

Can physicians improve patient satisfaction with long waiting times?

The purpose of our study was to determine how time spent with the physician might be related to patient dissatisfaction with their waiting time. During a 2-month period, patients in our internal medicine resident continuity clinic completed a survey assessing their satisfaction with their waiting time and their estimates of their waiting time and time spent with the resident physician. For patients with long waiting times (more than 15 min in the waiting room or more than 10 min in the exam room), patient dissatisfaction with waiting time was associated with a shorter physician visit (48% were dissatisfied if the physician spent less than 15 min vs. 18% if the physician spent more than 15 min with them, p = .03). These data suggest that physicians can mediate the negative effects of long waiting times by spending more time with their patients. Future studies on patient satisfaction should consider this interaction.

Are continuity clinic patients less satisfied when residents have a heavy inpatient workload?

The purpose of this study was to assess the influence of resident non-clinic workload on the satisfaction of continuity clinic patients. Over a 2-month period in 2002, residents and patients were surveyed at the University of Kentucky internal medicine continuity clinic. Residents provided a self-report of their non-clinic workload as light or medium versus heavy or extremely heavy. Patient satisfaction was assessed with a 7-item, 10-point scale with items derived from commonly used patient satisfaction instruments. In 168 patient encounters, patients were significantly less satisfied with their clinic visit if they were seen by a resident who had a heavier workload. In addition, these patients gave significantly lower ratings with regard to the amount of time spent with the patient during the visit, and how well the resident listened and paid attention. Although alternative explanations exist, we propose that heavy hospital workload is associated with decreased patient satisfaction in resident continuity clinic.

Exploring the type-of-crime hypothesis, religiosity, and spirituality in an adult male prison population.

This study examined the association between measures of spirituality and religiosity and characteristics of current criminal conviction in a male prison population. Spirituality was operationalized as spiritual well-being and existential well-being. Religiosity was operationalized as frequency of religious service attendance, whether an individual considered himself to be religious, and how strongly an individual believed his religious beliefs influenced his behavior. Inmates whose convictions were property related reported greater spiritual wellbeing, were more likely to consider themselves religious, and to say that religious beliefs influenced their behavior than inmates whose crimes were not property related. Inmates whose convictions were drug related were less likely to consider themselves religious, and inmates whose conviction involved violence were more likely to consider themselves religious but less likely to endorse statements that religious beliefs influenced their behavior. The distinction between religiosity and spirituality is discussed in terms of the type-of-crime hypothesis.

Post-traumatic stress disorder among patients with orofacial pain.

AIMS: To examine the presence and impact of post-traumatic stress disorder (PTSD) in a sample of patients seeking treatment for orofacial pain. METHODS: One hundred forty-one consecutive patients with an array of orofacial pain conditions were screened using a structured clinical interview for PTSD and the PTSD Symptom Checklist--Civilian Version (PCL), a brief PTSD self-report inventory. Additionally, participants received a clinical examination and self-report questionnaires to assess pain, coping styles, and presence of post-traumatic symptoms. RESULTS: Thirty-three (23%) patients received a full lifetime or current PTSD diagnosis, with an additional 11 patients receiving a partial PTSD diagnosis. Only 5 of these 44 patients had ever been previously diagnosed with PTSD. PTSD symptoms were associated with higher pain scores (P < .05) and affective distress (P < .01). Furthermore, discriminant function analyses suggested that the PCL accurately classified 89% of these cases (sensitivity = .85, specificity = .90, positive predictive power = 74%, negative predictive power = 95%). CONCLUSION: These results suggest that PTSD is prevalent in the orofacial pain setting and that PTSD symptomatology is associated with increased pain and affective distress that may complicate clinical presentation. Furthermore, PTSD can be accurately and efficiently assessed using a brief, self-report inventory.

Determinants of resident satisfaction with patients in their continuity clinic.

The purpose of this study was to identify what patient and physician factors influence resident satisfaction with patient encounters in a continuity clinic setting. Resident satisfaction was assessed from postencounter questionnaires completed by 68 internal medicine residents regarding 979 patient encounters. We found that residents were more satisfied with patients diagnosed with general medical problems than with patients diagnosed with pain and psychiatric disorders. First-year residents were less satisfied with patients diagnosed with pain and psychiatric disorders than second- and third-year residents. However, this dissatisfaction with seeing patients with pain or psychiatric disorders lessened as continuity of care was enhanced.

Are continuity clinic patients less satisfied when the resident is postcall?

Due to recent public debate and newly imposed resident work hour restrictions, we decided to investigate the relationship of resident call status to their ambulatory patients' satisfaction. Resident continuity clinic patients were asked to rate their level of satisfaction on a 10-point Likert-type scale. Using multiple regression approaches, these data were then assessed as a function of resident call status. We found that in 646 patient encounters, patient satisfaction scores were significantly less when the resident was postcall, 8.99 +/- 1.8, than when not postcall, 9.31 +/- 1.3. We herein discuss etiologies and implications of these findings for both patient care and medical education.

Improving students' sexual history inquiry and HIV counseling with an interactive workshop using standardized patients.

Sexual history and HIV counseling are essential clinical skills. Our project's purpose was to evaluate a standardized patient (SP) educational intervention teaching third-year medical students sexual history taking and HIV counseling. A 4-hour SP workshop was delivered to one-half of the class. Four weeks later, all students engaged in an SP examination including one station on assessing sexual history taking and HIV counseling. Workshop participants scored one standard deviation higher on sexual history and HIV counseling items than nonparticipants. Our sexual history and HIV counseling curriculum was associated with students asking more thorough sexual histories and providing more HIV counseling.

An exploratory examination of the Spiritual Well-Being Scale among incarcerated black and white male drug users.

A number of studies have examined the link between criminality and religiosity. However, only a limited number of studies have examined the relationship between spirituality and criminality. Because spirituality has been identified as a fundamental attribute of the personalities of Blacks, studies examining differences in the association between spirituality by ethnicity could provide information to understand the disparity of incarceration rates among Blacks and Whites. For this study, data were collected from 661 male prisoners with prior histories of drug use to examine spirituality that was assessed using two factors from a modified version of the Spiritual Well-Being Scale: relationship with a higher power and satisfaction with oneself in the world. Analyses revealed that White men reported significantly higher scores on both factors than Black men. The unexpected findings are discussed in light of the existing literature that identifies the significance of spirituality in the personality and coping style of Blacks.

The association of health-related quality of life and age of initiation of smoking.

OBJECTIVE: To assess the association between age of initiation of smoking and health-related quality of life. DESIGN: Secondary analysis of the 1997 Kentucky Health Survey. PARTICIPANTS: 677 Kentuckians aged 18 years or older. MEASUREMENTS AND RESULTS: Participants were classified as current, former, and never smokers. Early initiation of smoking was defined as beginning smoking at less than 15 years of age. All participants completed the Medical Outcomes Study Short Form Health Survey (SF-20). Decremental health-related quality of life scores were demonstrated for persons initiating smoking before the age of 15 on SF-20 subscales of mental health, health outlook, and social functioning (p < .05). These decrements on SF-20 subscales are more pronounced (p < .05) for females on all of the scales except for physical functioning. CONCLUSION: Regardless of current smoking status, people who initiate smoking before the age of 15 have a poorer health-related quality of life. Women who initiate smoking before age 15 appear to have a much poorer health-related quality of life than men.

Evaluation of commercial assays for vancomycin and aminoglycosides in serum: a comparison of accuracy and precision based on external quality assessment.

OBJECTIVE: To compare the accuracy and precision of commercial assay techniques in the measurement of gentamicin, tobramycin, amikacin, netilmicin and vancomycin in serum. METHODS: Data from the measurement of 40 external quality assessment samples from 358 laboratories providing a therapeutic drug monitoring service were analysed. RESULTS: Significant differences between techniques in accuracy and precision were observed for all drugs. Coefficients of variation ranged from 4.1% to 9.8% for the aminoglycosides and from 6.7% to 11.7% for vancomycin. The percentage difference in measurements from the weighed-in drug concentration ranged from -10.1% to +4.0% for the aminoglycosides and from -3.5% to +5.7% for vancomycin. The Dade Behring Emit immunoassay was notable in producing significantly more outliers (>4 S.D. from the weighed-in concentration) than other techniques in the measurement of gentamicin, amikacin and vancomycin. CONCLUSIONS: All assays performed to a satisfactory standard for measurement in non-renal patients, but none met the more stringent standards desirable for monitoring patients with renal impairment.
