A Case Study of Intractable Vomiting with Final Diagnosis of Neuromyelitis Optica.

This case study presents a patient living in a suburban/rural community who received appropriate referral to secondary and tertiary care for nausea and vomiting, accompanied by waxing and waning neurological symptoms, yet proved difficult to diagnose. This patient is presented to draw attention to a rare neurological disorder which should be included in the differential diagnosis of nausea and vomiting with some key neurological complaints, even in the absence of physical findings.

The symbolic and material nature of physician identity: implications for physician-patient communication.

This field study considers the implications of the symbolic and material nature of physician identity for communication with patients. In-depth interviews of physicians across multiple organizational contexts reveal that physician identity is a discursive process of situated meaning in which particular configurations of beliefs, values, and actions are constructed within specific contexts. The content of individual physician identity was related to the general environment of medicine and its local medical context. The identities of physicians working in private practice were linked to the economic, legal, and social environment of medicine, whereas physicians working as employees had identities related to working in a setting that buffered the effects of the environment. Specific implications of the symbolic and material nature of physician identity for physician-patient communication are examined. Understanding physician identity is important to health communication scholarship because of the ongoing and central nature of physicians in health-care decision making and delivery.

Physician discussion about social activities in primary care encounters with older adults.

OBJECTIVE: Involvement in social activities is linked to positive health outcomes. This study focused on the prevalence of social activity discussions during the primary care medical encounter, and examined how patient, physician, and contextual factors were associated with discussions between physicians and older patients. METHODS: The research was a secondary analysis of 434 videotapes recorded during primary care medical visits between 1998 and 2000 in outpatient clinics. Recordings were coded to identify a number of variables related to patient, physician, and companion characteristics, physician discussion on various topics, and quality of the physician's interaction with the patient. RESULTS: Physicians discussed social activity in only 31% of medical encounters. Variables significantly associated with social activity discussions included patient and physician race/ethnicity, physician age group, physician supportiveness, and the geographical site of the visit. CONCLUSION: Results support the inclusion of discussion and counseling about social activities in medical encounters with older patients. Family physicians will likely experience improved patient satisfaction, and geriatric patients can potentially reap health benefits that improve both quality of life and medical outcomes. Additional research is needed to understand more fully the correlates and benefits of social activity discussion during the medical encounter.

Learning basic surgical skills with mental imagery: using the simulation centre in the mind.

CONTEXT: Although surgeons and athletes frequently use mental imagery in preparing to perform, mental imagery has not been extensively researched as a learning technique in medical education. OBJECTIVE: A mental imagery rehearsal technique was experimentally compared with textbook study to determine the effects of each on the learning of basic surgical skills. METHODS: Sixty-four Year 2 medical students were randomly assigned to 2 treatment groups in which they undertook either mental imagery or textbook study. Both groups received the usual skills course of didactic lectures, demonstrations, physical practice with pigs' feet and a live animal laboratory. One group received additional training in mental imagery and the other group was given textbook study. Performance was assessed at 3 different time-points using a reliable rating scale. RESULTS: Analysis of variance on student performance in live rabbit surgery revealed a significant interaction favouring the imagery group over the textbook study group. CONCLUSIONS: The mental imagery technique appeared to transfer learning from practice to actual surgery better than textbook study.

A reliable and valid instrument to assess competency in basic surgical skills in second-year medical students.

BACKGROUND: Despite calls for competency based education, a dearth of validated instruments for measuring basic skills currently exists. We developed an instrument to assess competency in basic surgical skills in second-year medical students and tested it for psychometric reliability and validity. METHODS: From a review of the literature, an instrument comprised of numerically scaled items was constructed. After initial tests, several items were divided to produce a final instrument more specific and more appropriate for providing feedback to students. The final instrument was empirically tested for reliability and validity. RESULTS: The final 10-item instrument is presented here along with all of the empirical evidence including internal consistency reliability and interrater reliability, and content, criterion-related, and construct validity. Overall alpha reliability was 0.84 and interrater reliability was r = 0.83, P < 0.01 for the total scores. Factor analysis provided evidence of construct validity. CONCLUSIONS: The instrument has psychometric properties adequate for use as one criterion for summative evaluation and is educationally practical enough to provide focused and detailed feedback for student improvement.

Reaching and teaching preceptors: limited success from a multifaceted faculty development program.

We conducted a six-pronged preceptor faculty development program that included a listserve and interactive Web-based teaching scenarios. A total of 144 preceptors in a required preceptorship program were offered traditional continuing medical education (CME), a preceptor listserve, an electronic clinical teaching discussion group, an orientation videotape, a CD-ROM on teaching skills, and technology support. On Web-based evaluation, 31% of participants responded. Eighty percent of preceptors allowed us to subscribe them to the listserve, and most agreed it was useful. One third of preceptors responded to an electronic clinical teaching case discussion, most rating it useful to their precepting. The listserve and electronic teaching cases hold promise for preceptor faculty development.

Decision or no decision: how do patient-physician interactions end and what matters?

BACKGROUND: A clearly stated clinical decision can induce a cognitive closure in patients and is an important investment in the end of patient-physician communications. Little is known about how often explicit decisions are made in primary care visits. OBJECTIVE: To use an innovative videotape analysis approach to assess physicians' propensity to state decisions explicitly, and to examine the factors influencing decision patterns. DESIGN: We coded topics discussed in 395 videotapes of primary care visits, noting the number of instances and the length of discussions on each topic, and how discussions ended. A regression analysis tested the relationship between explicit decisions and visit factors such as the nature of topics under discussion, instances of discussion, the amount of time the patient spoke, and competing demands from other topics. RESULTS: About 77% of topics ended with explicit decisions. Patients spoke for an average of 58 seconds total per topic. Patients spoke more during topics that ended with an explicit decision, (67 seconds), compared with 36 seconds otherwise. The number of instances of a topic was associated with higher odds of having an explicit decision (OR = 1.73, p < 0.01). Increases in the number of topics discussed in visits (OR = 0.95, p < .05), and topics on lifestyle and habits (OR = 0.60, p < .01) were associated with lower odds of explicit decisions. CONCLUSIONS: Although discussions often ended with explicit decisions, there were variations related to the content and dynamics of interactions. We recommend strengthening patients' voice and developing clinical tools, e.g., an "exit prescription," to improving decision making.

Prevalence and correlates of doctor-geriatric patient lifestyle discussions: analysis of ADEPT videotapes.

BACKGROUND: This study identifies the prevalence and correlates of physician-geriatric patient discussions about physical activity and nutrition lifestyle behaviors. METHODS: Between August 1998 and July 2000, 423 older patient visits to 36 physicians were videotaped in three different primary care settings. The patient sample was primarily white, female, well-educated, and financially sufficient, although 12.7% of the encounters occurred in an inner city clinic. The major dependent variable-lifestyle discussion-is based on observations of physician behavior. Descriptive and multivariate logistic regression analyses were conducted in 2004. RESULTS: Nutrition talk was most prevalent, occurring in almost half the encounters (48.2%) followed by physical activity discussions (39.2%) then conjoint mention (22%). Discussions were significantly less likely to occur in acute visits. While ethnicity, gender, and length of visit were not significantly related, physician interaction style and patient vitality and education were significant predictors in the multivariate analyses. CONCLUSIONS: Given the impact of lifestyle behaviors on myriad health outcomes, the current prevalence rates of physician discussion, while higher than in many previous studies, remain sub-optimal. Practical assessment tools, training in behavioral counseling, and reimbursement incentives are recommended strategies for raising physical activity and nutrition discussion prevalence in primary care settings.

Understanding primary care physicians' propensity to assess elderly patients for depression using interaction and survey data.

OBJECTIVE: The objective of this study was to examine primary care physicians' propensity to assess their elderly patients for depression using data from videotapes and patient and physician surveys. STUDY DESIGN: An observational study was informed by surveys of 389 patients and 33 physicians, and 389 videotapes of their clinical interactions. Secondary quantitative analyses used video data scored by the Assessment of Doctor-Elderly Patient Transactions system regarding depression assessment. A random-effects logit model was used to analyze the effects of patient health, competing demands, and racial and gender concordance on physicians' propensity to assess elderly patients for depression. RESULTS: Physicians assessed depression in only 14% of the visits. The use of formal depression assessment tools occurred only 3 times. White patients were almost 7 times more likely than nonwhite patients to be assessed for depression (odds ratio [OR], 6.9; P < 0.01). Depression assessment was less likely if the patient functioned better emotionally (OR, 0.95; P < 0.01). The propensity of depression assessment was higher in visits that covered multiple topics (OR, 1.3; P < 0.01) contrary to the notion of competing demands crowding out mental health services. Unexpectedly, depression assessment was less likely to occur in gender and racially concordant patient-physician dyads. CONCLUSIONS: Primary care physicians assessed their elderly patients for depression infrequently. Reducing the number of topics covered in visits and matching patients and physicians based on race and gender may be counterproductive to depression detection. Informed by videotapes and surveys, our findings offer new insights on the actual care process and present conclusions that are different from studies based on administrative or survey data alone.

An efficient method of identifying major depression and panic disorder in primary care.

The research literature is replete with evidence of and concerns about the prevalence and undertreatment of mental disorders in primary care. Although screening, on its own, may not directly affect clinical outcomes, it is still the most efficient and effective way to identify psychologically distressed patients for either research purposes or to provide patients with or refer patients to appropriate care. The current study sought to establish the utility of the MHI-5 for the detection of patients suffering from major depression or panic disorder, two of the most common psychiatric conditions seen in primary care settings. This study was conducted in a family medicine clinic and 246 adult outpatients participated. Patients completed the Mental Health Index-5 (MHI-5) as the screening measure and the PRIME-MD Patient Health Questionnaire (PHQ) as the diagnostic instrument. ROC analyses indicated that a cut-off score of 23 on the MHI-5 yielded a sensitivity of 91% and a specificity of 58% for predicting provisional diagnoses of major depression or panic disorder from the PHQ. Using a single item to screen for a PHQ diagnosis of major depression yielded a sensitivity of 88% and a specificity of 62% and a second question had a sensitivity of 100% and specificity of 63% for PHQ diagnosis of panic disorder. These results indicate that it is possible to use a small number of items to efficiently and effectively screen for mental disorders affecting a significant portion of primary care patients.

Comparing the effects of physical practice and mental imagery rehearsal on learning basic surgical skills by medical students.

OBJECTIVE: The purpose of this study was to test the effects of varying the amount of physical practice and mental imagery rehearsal on learning basic surgical procedures. STUDY DESIGN: Using a sample of 65 second-year medical students, 3 randomized groups received either: (1) 3 sessions of physical practice on suturing a pig's foot; (2) 2 sessions of physical practice and 1 session of mental imagery rehearsal; or (3) 1 session of physical practice and 2 sessions of imagery rehearsal. All participants then performed a surgery on a live rabbit in the operating theater of a veterinary college under approved conditions. Analysis of variance was applied to pre- and post-treatment ratings of surgical performance. RESULTS: Physical practice followed by mental imagery rehearsal was statistically equal to additional physical practice. CONCLUSION: Initial physical practice followed by mental imagery rehearsal may be a cost-effective method of training medical students in learning basic surgical skills.

Attitudes of veterinary medical students and medical students toward collaborative learning: an experiment.

This study measured the attitudes of 55 medical students and 30 veterinary medical students as they participated in an experiment of collaborative teaching and learning about basic surgical skills. Two parallel forms of an attitude questionnaire were developed, with three subscales: confidence in one's own surgical skill; collaboration with the other type of student; and inter-professional collaboration in general. These attitude scales were administered before and after an experiment involving the veterinary medical students teaching the medical students incision and exploratory laparoscopy in a laboratory setting using live rabbits. After the experiment, measures of the medical students' attitudes had increased significantly on all three subscales. Measures of the veterinary students' attitudes increased significantly on two subscales but declined on the subscale of inter-professional collaboration.
