Objective: To measure the impact of a teaching intervention and to compare process and outcomes of care for HIV-infected patients randomly assigned to a general medicine clinic (GMC) or an infectious disease clinic (IDC) for primary care.Design: Prospective, randomized, controlled trial.Setting: University hospital in Durham, NC.Patients: Two hundred fourteen consecutive HIV-infected patients presenting for primary care.Intervention: Physicians at the GMC received HIV-related training and evidence-based practice guidelines.Measurements: Utilization of services, health-related quality of life, preventive and screening measures, and antiretroviral use for one year.Results: At baseline GMC patients were more likely to be African American (85% vs 71%; P =.03) and had lower baseline CD4+ cell counts than IDC patients (262 +/- 269 vs 329 +/- 275; P =.05). A similar and high proportion of patients in both groups received appropriate preventive care services including Pneumocystis carinii pneumonia (PCP) prophylaxis, pneumococcal vaccination, and antiretroviral therapy. Screening for TB was more frequent in GMC (89% vs 68%; P =.001). In the year following randomization, GMC patients made more visits to the emergency department than IDC patients (1.6 +/- 3.0 vs 0.7 +/- 1.5; P =.05). Hospital use was higher for GMC patients with average length of stay 7.8 +/- 6.3 days compared to 5.7 +/- 3.8 days for IDC patients (P =.01). In analyses, which adjust for potential baseline imbalances, these differences remained.Conclusions: Targeted education in GMC achieved similar provision of primary care for GMC patients, yet use of health care services was higher for this group. The delivery of adequate primary care is necessary but not sufficient to produce changes in health care utilization. [ABSTRACT FROM AUTHOR]

Main Results: Compared with younger patients, patients aged 50 years or older were less likely to have acquired HIV via intravenous drug use or homosexual contact (p = .0001). Older patients were more likely to have comorbid diseases (12% vs 4%; p = .0001), had more frequent neurologic findings on admission (19% vs 9%; p = .0001), and scored higher on a PCP-specific severity-of-illness scale indicating more severe disease (p = .0001). Older patients had more intensive care unit admissions and intubations (p = .0001). Patients aged 50 years or older were less likely to have a diagnosis of HIV mentioned in their progress notes during the first 2 days of admission (75% vs 85%; p = .0001), less likely to receive PCP-specific therapy within the first 2 hospital days (58% vs 76%; p = .0001), and more likely to receive steroids (32% vs 22%; p = .0001). Older patients had a greater in-hospital mortality (32% vs 18%; p = .0001). However, in logistic regression analysis with mortality as the outcome, the effect of older age was diminished when adjustments were made for insurance status, severity of illness, comorbidity, timely PCP therapy, and inpatient use of steroids.Conclusions: Age differences in mortality for AIDS-related PCP may be explained by increased severity of presenting illness, underrecognition of HIV, and delay in initiation of PCP-specific therapy. Physicians may need to consider HIV-related infections for persons aged 50 years or older at risk of HIV infection. [ABSTRACT FROM AUTHOR]

Abstract Background Learner satisfaction assessment is critical in the design and improvement of training programs. However, little is known about what influences satisfaction and whether trainee specialty is correlated. A national comparison of satisfaction among internal medicine subspecialty fellows in the Department of Veterans Affairs (VA) provides a unique opportunity to examine educational factors associated with learner satisfaction. We compared satisfaction across internal medicine fellows by subspecialty and compared factors associated with satisfaction between procedural versus non-procedural subspecialty fellows, using data from the Learners' Perceptions Survey (LPS), a validated survey tool. Methods We surveyed 2,221 internal medicine subspecialty fellows rotating through VA between 2001 and 2008. Learners rated their overall training satisfaction on a 100-point scale, and on a five-point Likert scale ranked satisfaction with items within six educational domains: learning, clinical, working and physical environments; personal experience; and clinical faculty/preceptor. Results Procedural and non-procedural fellows reported similar overall satisfaction scores (81.2 and 81.6). Non-procedural fellows reported higher satisfaction with 79 of 81 items within the 6 domains and with the domain of physical environment (4.06 vs. 3.85, p Conclusions Internal medicine fellows are highly satisfied with their VA training. Nonprocedural fellows reported higher satisfaction with most items. For both procedural and non-procedural fellows, clinical faculty/preceptor and personal experience have the strongest impact on overall satisfaction.

Abstract Background Supporting 21st century health care and the practice of evidence-based medicine (EBM) requires ubiquitous access to clinical information and to knowledge-based resources to answer clinical questions. Many questions go unanswered, however, due to lack of skills in formulating questions, crafting effective search strategies, and accessing databases to identify best levels of evidence. Methods This randomized trial was designed as a pilot study to measure the relevancy of search results using three different interfaces for the PubMed search system. Two of the search interfaces utilized a specific framework called PICO, which was designed to focus clinical questions and to prompt for publication type or type of question asked. The third interface was the standard PubMed interface readily available on the Web. Study subjects were recruited from interns and residents on an inpatient general medicine rotation at an academic medical center in the US. Thirty-one subjects were randomized to one of the three interfaces, given 3 clinical questions, and asked to search PubMed for a set of relevant articles that would provide an answer for each question. The success of the search results was determined by a precision score, which compared the number of relevant or gold standard articles retrieved in a result set to the total number of articles retrieved in that set. Results Participants using the PICO templates (Protocol A or Protocol B) had higher precision scores for each question than the participants who used Protocol C, the standard PubMed Web interface. (Question 1: A = 35%, B = 28%, C = 20%; Question 2: A = 5%, B = 6%, C = 4%; Question 3: A = 1%, B = 0%, C = 0%) 95% confidence intervals were calculated for the precision for each question using a lower boundary of zero. However, the 95% confidence limits were overlapping, suggesting no statistical difference between the groups. Conclusion Due to the small number of searches for each arm, this pilot study could not demonstrate a statistically significant difference between the search protocols. However there was a trend towards higher precision that needs to be investigated in a larger study to determine if PICO can improve the relevancy of search results.

Background: In spring 2020, the COVID-19 pandemic overwhelmed intensive care teams with severely ill patients. Even at the end of life, families were barred from hospitals, relying solely on remote communication. A Remote Communication Liaison Program (RCLP) was established to ensure daily communication for families, while supporting overstretched intensivists. Objectives: To evaluate the effectiveness and impact of the RCLP on participating liaisons and intensivists. Design: Two quality improvement surveys were developed and administered electronically. Setting/Subjects: Based in the United States, all liaisons and intensivists who participated in this program were invited to take the surveys. Measurements: Descriptive statistics were used to analyze the quantitative Likert-scale data, and qualitative analysis was used to assess themes. Results: Among respondents, all (100%) liaisons and more than 90% of intensivists agreed or strongly agreed that the RCLP provided a valuable service to families. More than 70% of intensivists agreed or strongly agreed that the program lessened their workload. More than 90% of liaisons agreed or strongly agreed that participation in the program improved their confidence and skills in end-of-life decision making, difficult conversations, and comprehension of critical care charts. Themes elicited from the liaisons revealed that participation fostered a renewed sense of purpose as physicians, meaningful connection, and opportunities for growth. Conclusions: RCLP successfully trained and deployed liaisons to rapidly develop skills in communication with beleaguered families during COVID-19 surge. Participation in the program had a profound effect on liaisons, who experienced a renewed sense of meaning and connection to the practice of medicine.

Decision analysis is a tool that clinicians can use to choose an option that maximizes the overall net benefit to a patient. It is an explicit, quantitative, and systematic approach to decision making under conditions of uncertainty. In this article, we present two teaching tips aimed at helping clinical learners understand the use and relevance of decision analysis. The first tip demonstrates the structure of a decision tree. With this tree, a clinician may identify the optimal choice among complicated options by calculating probabilities of events and incorporating patient valuations of possible outcomes. The second tip demonstrates how to address uncertainty regarding the estimates used in a decision tree. We field tested the tips twice with interns and senior residents. Teacher preparatory time was approximately 90 minutes. The field test utilized a board and a calculator. Two handouts were prepared. Learners identified the importance of incorporating values into the decision-making process as well as the role of uncertainty. The educational objectives appeared to be reached. These teaching tips introduce clinical learners to decision analysis in a fashion aimed to illustrate principles of clinical reasoning and how patient values can be actively incorporated into complex decision making.

Background: Clinical prediction rules (CPR) are tools that clinicians can use to predict the most likely diagnosis, prognosis, or response to treatment in a patient based on individual characteristics. CPRs attempt to standardize, simplify, and increase the accuracy of clinicians' diagnostic and prognostic assessments. The teaching tips series is designed to give teachers advice and materials they can use to attain specific educational objectives., Educational Objectives: In this article, we present 3 teaching tips aimed at helping clinical learners use clinical prediction rules and to more accurately assess pretest probability in every day practice. The first tip is designed to demonstrate variability in physician estimation of pretest probability. The second tip demonstrates how the estimate of pretest probability influences the interpretation of diagnostic tests and patient management. The third tip exposes learners to various examples and different types of Clinical Prediction Rules (CPR) and how to apply them in practice. PILOT TESTING: We field tested all 3 tips with 16 learners, a mix of interns and senior residents. Teacher preparatory time was approximately 2 hours. The field test utilized a board and a data projector; 3 handouts were prepared. The tips were felt to be clear and the educational objectives reached. Potential teaching pitfalls were identified., Conclusion: Teaching with these tips will help physicians appreciate the importance of applying evidence to their every day decisions. In 2 or 3 short teaching sessions, clinicians can also become familiar with the use of CPRs in applying evidence consistently in everyday practice.

However, in logistic regression analysis with mortality as the outcome, the effect of older age was diminished when adjustments were made for insurance status, severity of illness, comorbidity, timely PCP therapy, and inpatient use of steroids., Conclusions: Age differences in mortality for AIDS-related PCP may be explained by increased severity of presenting illness, underrecognition of HIV, and delay in initiation of PCP-specific therapy. Physicians may need to consider HIV-related infections for persons aged 50 years or older at risk of HIV infection.

Vascular smooth muscle tone is modulated in vivo by the functional interaction of a variety of vasoconstrictor and vasodilator stimuli. Endogenous substances (e.g., epinephrine) acting on smooth muscle, simultaneously activate alpha-adrenergic receptors (alpha-AR) eliciting contraction and beta-adrenergic receptors (beta-AR) which relax the muscle. This study characterizes the beta-adrenergic response in the isolated rabbit aorta precontracted with phenylephrine (PE) or serotonin (5-hydroxytryptamine [5-HT]). The beta-adrenergic agonist isoproterenol (ISO) produces a biphasic response that is composed of a rapid relaxation followed by a slower regaining of tension identified as desensitization. An exploratory kinetic model that describes both relaxation and desensitization as first order processes provides a good description of the experimental data. The five parameters used to describe the ISO response are: the observed rate constants for relaxation and desensitization (krel and kdes), the fractional magnitudes of the changes in tension for the two processes (R/C) and D/R), and the observed delay in the onset of the desensitization response, td. The krel and R/C were dependent on concentration of ISO in a saturable manner in rings precontracted with either 1 mumol/L PE or 1 mumol/L 5-HT and inversely related to the concentration of the contractile agonist. Yet, although the degree of fractional relaxation in the presence of PE covered the full range, that of 5-HT extended over a range of 20%. This behavior leads to the conclusion that the functional interaction between the contractile and relaxing stimuli is non additive. No dependence on the concentration of ISO was observed for D/R, kdes, and td.(ABSTRACT TRUNCATED AT 250 WORDS)
