RESUMO

AIMS: This study compared three artificial intelligence (AI) platforms' potential to identify drug therapy communication competencies expected of a graduating medical doctor. METHODS: We presented three AI platforms, namely, Poe Assistant©, ChatGPT© and Google Bard©, with structured queries to generate communication skill competencies and case scenarios appropriate for graduating medical doctors. These case scenarios comprised 15 prototypical medical conditions that required drug prescriptions. Two authors independently evaluated the AI-enhanced clinical encounters, which integrated a diverse range of information to create patient-centred care plans. Through a consensus-based approach using a checklist, the communication components generated for each scenario were assessed. The instructions and warnings provided for each case scenario were evaluated by referencing the British National Formulary. RESULTS: AI platforms demonstrated overlap in competency domains generated, albeit with variations in wording. The domains of knowledge (basic and clinical pharmacology, prescribing, communication and drug safety) were unanimously recognized by all platforms. A broad consensus among Poe Assistant© and ChatGPT© on drug therapy-related communication issues specific to each case scenario was evident. The consensus primarily encompassed salutation, generic drug prescribed, treatment goals and follow-up schedules. Differences were observed in patient instruction clarity, listed side effects, warnings and patient empowerment. Google Bard did not provide guidance on patient communication issues. CONCLUSIONS: AI platforms recognized competencies with variations in how these were stated. Poe Assistant© and ChatGPT© exhibited alignment of communication issues. However, significant discrepancies were observed in specific skill components, indicating the necessity of human intervention to critically evaluate AI-generated outputs.

RESUMO

BACKGROUND: Artificial intelligence (AI) tools are designed to create or generate content from their trained parameters using an online conversational interface. AI has opened new avenues in redefining the role boundaries of teachers and learners and has the potential to impact the teaching-learning process. METHODS: In this descriptive proof-of- concept cross-sectional study we have explored the application of three generative AI tools on drug treatment of hypertension theme to generate: (1) specific learning outcomes (SLOs); (2) test items (MCQs- A type and case cluster; SAQs; OSPE); (3) test standard-setting parameters for medical students. RESULTS: Analysis of AI-generated output showed profound homology but divergence in quality and responsiveness to refining search queries. The SLOs identified key domains of antihypertensive pharmacology and therapeutics relevant to stages of the medical program, stated with appropriate action verbs as per Bloom's taxonomy. Test items often had clinical vignettes aligned with the key domain stated in search queries. Some test items related to A-type MCQs had construction defects, multiple correct answers, and dubious appropriateness to the learner's stage. ChatGPT generated explanations for test items, this enhancing usefulness to support self-study by learners. Integrated case-cluster items had focused clinical case description vignettes, integration across disciplines, and targeted higher levels of competencies. The response of AI tools on standard-setting varied. Individual questions for each SAQ clinical scenario were mostly open-ended. The AI-generated OSPE test items were appropriate for the learner's stage and identified relevant pharmacotherapeutic issues. The model answers supplied for both SAQs and OSPEs can aid course instructors in planning classroom lessons, identifying suitable instructional methods, establishing rubrics for grading, and for learners as a study guide. Key lessons learnt for improving AI-generated test item quality are outlined. CONCLUSIONS: AI tools are useful adjuncts to plan instructional methods, identify themes for test blueprinting, generate test items, and guide test standard-setting appropriate to learners' stage in the medical program. However, experts need to review the content validity of AI-generated output. We expect AIs to influence the medical education landscape to empower learners, and to align competencies with curriculum implementation. AI literacy is an essential competency for health professionals.

RESUMO

BACKGROUND: Emotional intelligence (EI) is a predictive factor of academic success in undergraduate Doctor of Medicine (MD) programs. Although some research suggests a positive association between EI and academic success in MD programs, other research reports neither an association nor a negative correlation between the two variables. The current study aimed to resolve these contradictory findings by conducting a systematic review and a meta-analysis using research from 2005 to 2022. METHODS: Data were analyzed using a multilevel modeling approach to (a) estimate the overall relationship between EI and academic success in MD programs and (b) determine whether the mean effect size varies according to country (United States vs. non-United States countries), age, EI test, EI task nature (ability-based vs. trait-based), EI subscales, and academic performance criteria (grade point average vs. examinations). RESULTS: Findings from 20 studies (m = 105; N = 4,227) indicated a positive correlation between EI and academic success (r = .13, 95% CI [.08, - .27], p < .01). Moderator analyses indicated that the mean effect size significantly varied according to EI tests and EI subscales. Moreover, three-level multiple regression analyses showed that between-study variance explained 29.5% of the variability in the mean effect size, whereas within-study variance explained 33.5% of the variability in the mean effect. CONCLUSIONS: Overall, the current findings show that EI is significantly, albeit weakly, related to academic success in MD programs. Medical researchers and practitioners can therefore focus on integrating EI-related skills into the MD curriculum or target them through professional development training and programs.

RESUMO

BACKGROUND: Malaria caused by Plasmodium falciparum in pregnancy can result in adverse maternal and fetal sequelae. This review evaluated the adherence of the national guidelines drawn from World Health Organization (WHO) regions, Africa, Eastern Mediterranean, Southeast Asia, and Western Pacific, to the WHO recommendations on drug treatment and prevention of chloroquine-resistant falciparum malaria in pregnant women. METHODS: Thirty-five updated national guidelines and the President's Malaria Initiative (PMI), available in English language, were reviewed. The primary outcome measures were the first-line anti-malarial treatment protocols adopted by national guidelines for uncomplicated and complicated falciparum malaria infections in early (first) and late (second and third) trimesters of pregnancy. The strategy of intermittent preventive treatment of malaria in pregnancy (IPTp) with sulfadoxine-pyrimethamine (SP) was also addressed. RESULTS: This review evaluated the treatment and prevention of falciparum malaria in pregnancy in 35 national guidelines/PMI-Malaria Operational Plans (MOP) reports out of 95 malaria-endemic countries. Of the 35 national guidelines, 10 (28.6%) recommend oral quinine plus clindamycin as first-line treatment for uncomplicated malaria in the first trimester. As the first-line option, artemether-lumefantrine, an artemisinin-based combination therapy, is adopted by 26 (74.3%) of the guidelines for treating uncomplicated or complicated malaria in the second and third trimesters. Intravenous artesunate is approved by 18 (51.4%) and 31 (88.6%) guidelines for treating complicated malaria during early and late pregnancy, respectively. Of the 23 national guidelines that recommend IPTp-SP strategy, 8 (34.8%) are not explicit about directly observed therapy requirements, and three-quarters, 17 (73.9%), do not specify contra-indication of SP in human immunodeficiency virus (HIV)-infected pregnant women receiving cotrimoxazole prophylaxis. Most of the guidelines (18/23; 78.3%) state the recommended folic acid dose. CONCLUSION: Several national guidelines and PMI reports require update revisions to harmonize with international guidelines and emergent trends in managing falciparum malaria in pregnancy. National guidelines and those of donor agencies should comply with those of WHO guideline recommendations although local conditions and delayed guideline updates may call for deviations from WHO evidence-based guidelines.

RESUMO

OBJECTIVES: This study evaluated the prevalence of prescribing drugs with constipation-inducing potential and the prophylactic use of laxatives in community-dwelling older adults. METHOD: An audit of outpatient prescriptions ordered for older adults aged ≥65 years with one or more chronic morbidities in 24 governmental primary healthcare centres in Bahrain. The prescriptions were collected by pharmacist-in-charge of each health centre between December 2015 and June 2016. The proportion of prescriptions with constipation-inducing drugs and co-prescribed laxatives was determined. KEY FINDINGS: The overall prevalence of prescribing drugs with the potential to cause constipation was 30.5% (642/2106). Prescriptions with at least one anticholinergic/drug with anticholinergic potential (DAP) were 22.5% (473/2106): single medication in 16.6% (350/2106) and two or more combinations in 5.9% (124/2106). A combination of two or more anticholinergics/DAP accounted for 2.9% (61/2106) prescriptions. Constipation-inducing drugs other than anticholinergics such as multivalent cation preparations and non-dihydropyridine calcium channel blockers were prescribed in 8.0% (168/2106) of cases. Orphenadrine and first-generation antihistamines, both with high anticholinergic drug burden, were the frequently prescribed medications, either alone or combined. The rate of prescribed laxatives was 2.96% (19/642), mostly for those on constipation-inducing drug monotherapy. CONCLUSION: Approximately a third of prescriptions for older adults had constipation-inducing medications, typically a single DAP. Prescribing laxatives were uncommon and did not correlate with the prevalence of prescribing drugs with constipation potential. Physicians' awareness about anticholinergic drugs and their potential risks, and the prophylactic use of laxatives to mitigate iatrogenic constipation are to be included in continuing professional programmes.

RESUMO

INTRODUCTION: Hypertension, if not appropriately treated, is associated with life-threatening complications. AIMS: This study evaluated antihypertensive prescribing patterns in older adults (≥ 65 years) versus young adults based on the current guidelines with an emphasis on the use of dual single-pill combinations (SPCs). METHODS: A nationwide audit of 8746 primary care prescriptions of hypertensive patients with comorbidities in Bahrain was performed. RESULTS: Antihypertensive combination therapy was prescribed more often to older (77.1%) than young adults (68.6%; P < 0.0001) whereas SPCs were under-used (57.6% vs. 69.4%; P < 0.0001). Recommended dual SPCs, without/with a combination of a free-dose complementary antihypertensive agent, were significantly less often prescribed for the older adult as compared to young adult adults (45.1% vs. 62.99% and 35.97% vs. 46.72%; P < 0.0001), respectively. Unacceptable two- and three-drug combinations (including those with limited clinical evidence and unacceptable ones) were prescribed more often to older adults rather than to young ones (20.06% vs. 12.6%; and 56.5% vs. 46.8%; P < 0.0001), respectively. In both age groups, the top-three antihypertensive classes prescribed as monotherapy were angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and ß blockers. CONCLUSION: The updated guidelines for hypertension treatment in older adults have had a limited impact on primary care practice in Bahrain. In both age groups, there was a high positive correlation between the number of antihypertensive drugs prescribed and prescribing unacceptable combinations. Unacceptable combinations comprising SPC-related antihypertensive therapy duplication were more common than those reported elsewhere. Introducing approved triple SPCs may discourage prescribing unacceptable antihypertensive drugs and their combinations that lack robust evidence.

RESUMO

BACKGROUND: The relationship between large-group classroom attendance by students and test achievement in problem-based learning (PBL) curricula is unclear. This study examined the correlation between attendance at resource sessions (hybrid lectures in the PBL curriculum) and test scores achieved in pharmacology and determined whether the score achieved was related to student gender. METHODS: A cross-sectional observational study over one academic year of 1404 pre-clerkship medical students was performed. Class attendance during pharmacology resource sessions and MCQ test scores achieved in pharmacology were analysed. RESULTS: The percentage of students' attendance in resource sessions declined over three years of the programme, from 78.7 ± 27.5 in unit I to 22.1 ± 35.6 (mean ± SD) in unit IX. A significant but weakly positive correlation was evident between attendance and achievement in pharmacology (r = 0.280; p < 0.0001). The mean score of the students who attended > 50% of the resource sessions was significantly higher (p < 0.0001). Students who attended ≤50% were more likely to achieve lower tertile scores. The mean score achieved and the number of higher tertile scorers were higher among students who attended > 50% of the resource sessions. Although female students' attendance was significantly higher, no significant gender-related differences in either mean scores or top grades achieved were found. CONCLUSIONS: In a PBL curriculum, the classroom attendance of students in pharmacology declined during the pre-clerkship phase. A weak positive correlation was found between attendance and academic achievement, as measured by MCQ test scores. Factors other than motivation and attendance may confound gender-based academic performance and merit further research.

RESUMO

BACKGROUND: Data on the potential effects of maternal exposure to melamine is scarce. We aimed to evaluate the impact of melamine administration on pregnancy outcome and foetal growth in rats. METHODS: Positively-mated female Sprague-Dawley rats (n=24) were treated from day 6 to day 20 of gestation with vehicle (control), melamine 300 mg/kg/day (group-1) or melamine 450 mg/kg/day (group 2). On day 21, the numbers of foetal resorptions and dead foetuses were recorded. Thereafter, pups were examined for external anomalies, and various growth parameters were measured. RESULTS: A remarkable increase in the number of resorptions was observed in group-2 compared to the other two groups. A significant increase in foetal weight and placental weight was seen in group-2 compared to control. Head length and placental diameter were low in group-1 compared to control. The ratio between crown-rump length and head length was significantly greater in group 2 compared to control indicating asymmetrical intrauterine growth restriction. The only influence observed in group 1 compared to control was a decrease in placental diameter. No gross foetal malformations or changes in umbilical cord length, crownrump length or biparietal diameter were observed in both melamine-treated groups. CONCLUSIONS: Maternal exposure to melamine during pregnancy increased the incidence of resorption and resulted in asymmetrical intrauterine growth restriction.

RESUMO

AIM: Several drugs have been used for treating non-alcoholic fatty liver disease (NAFLD). The present study is a network meta-analysis of such drugs. DESIGN, SETTING AND PATIENTS: Randomised clinical trials comparing drug interventions in patients with NAFLD were analysed. OR and weighted mean difference (95 % CI) were the effect estimates for categorical and numerical outcomes, respectively. Random-effects model was used to generate pooled estimates. Surface under the cumulative ranking curve was used to rank the treatments. MAIN OUTCOME MEASURES: Proportion of responders was the primary outcome measure and non-alcoholic steatohepatitis scores, liver enzymes, lipid profile, body mass index, homeostatic model assessment of insulin resistance, intrahepatic fat and adverse events were the key secondary outcomes. RESULTS: 116 studies were included in the systematic review and 106 in the meta-analysis. Elafibranor, gemfibrozil, metadoxine, obeticholic acid, pentoxifylline, pioglitazone, probiotics, telmisartan, vildagliptin and vitamin E significantly increased the response rate than standard of care. Various other drugs were observed to modify the secondary outcomes favourably. Probiotics was found with a better response in children; and elafibranor, obeticholic acid, pentoxifylline and pioglitazone in patients with type 2 diabetes mellitus. The quality of evidence observed was either low or very low. CONCLUSION: In patients with NAFLD, several drugs have been shown to have variable therapeutic benefit. However, the estimates and the inferences should be considered with extreme caution as it might change with the advent of future head-to-head clinical trials.

RESUMO

AIMS: Several antihypertensive drugs are used in the treatment of severe hypertension in pregnancy. The present study is a network meta-analysis comparing the efficacy and safety of these drugs. METHODS: Electronic databases were searched for randomized clinical trials comparing drugs used in the treatment of severe hypertension in pregnancy. The number of women achieving the target blood pressure (BP) was the primary outcome. Doses required and time taken for achieving the target BP, failure rate, and incidences of maternal tachycardia, palpitation, hypotension, headache, and neonatal death and stillbirth were the secondary outcomes. Mixed treatment comparison pooled estimates were generated using a random-effects model. Odds ratios for the categorical and mean difference for the numerical outcomes were the effect estimates. RESULTS: Fifty-one studies were included in the systematic review and 46 in the meta-analysis. No significant differences in the number of patients achieving target BP was observed between any of the drugs. Diazoxide [-15 (-20.6, -9.4)], nicardipine [-11.8 (-22.3, -1.2)], nifedipine/celastrol [-19.3 (-27.4, -11.1)], nifedipine/vitamin D [-17.1 (-25.7, -9.7)], nifedipine/resveratrol [-13.9 (-22.6, -5.2)] and glyceryl trinitrate [-33.8 (-36.7, -31)] were observed to achieve the target BP (in minutes) more rapidly than hydralazine. Nifedipine required fewer doses than hydralazine for achieving the target BP. Glyceryl trinitrate and labetalol were associated with fewer incidences of tachycardia and palpitation respectively than hydralazine. Trial sequential analysis concluded adequate evidence for hydralazine and nifedipine compared with labetalol. Moderate quality of evidence was observed for direct comparison estimate between labetalol and hydralazine but was either low or very low for other comparisons. CONCLUSION: The present evidence suggests similar efficacy between nifedipine, hydralazine and labetalol in the treatment of severe hypertension in pregnancy. Subtle differences may exist in their safety profile. The evidence is inadequate for other drugs.

RESUMO

Premature ejaculation (PE) is the most common sexual dysfunction in men. The present study is a network meta-analysis of drugs used for treating PE. Electronic databases were searched for randomized controlled trials comparing medical interventions with either placebo or with other active drugs in patients with PE. Inverse variance heterogeneity model was used for mixed-treatment comparisons. Intravaginal ejaculatory latency time (IELT) and adverse events were the main outcome measures. A total of 44 studies were included in the meta-analysis. Dapoxetine 30 and 60 mg, tadalafil, sildenafil, paroxetine with sildenafil, topical lidocaine, dapoxetine 30 mg with mirodenafil, vardenafil, fluoxetine, and tadalafil, pindolol with paroxetine, tramadol, topical lidocaine with tadalafil, paroxetine with tadalafil, and topical eutectic mixture of local anesthetics were associated with a significant increase in IELT. Similarly, dapoxetine 60 mg, venlafaxine, fluoxetine, tramadol at 25, 50, and 100 mg, and combined fluoxetine and tadalafil were associated with an increased risk of adverse events. Dapoxetine 30 mg has a high likelihood of being the "best" in the interventional pool. Dapoxetine at 30 mg could be used as the first-line agent in the management of PE.

RESUMO

Dissemination of misleading drug information through social media can be detrimental to the health of the public. This study, carried out in Bahrain, evaluated the truthfulness of 22 social media claims about drugs (72.7%), dietary supplements (22.7%), and toxic bisphenol-A (4.5%). They circulated on WhatsApp platform, as case studies. We categorized claims as objectively true, false, or potentially misleading. The content analysis revealed that "potentially misleading" claims were the most frequent messages (59.1%). They tend to exaggerate the efficacy or safety without sufficient evidence to substantiate claims. False claims (27.3%) were likely due to unfair competition or deception. Overall, 13.6% of the messages were objectively true claims that could withstand regulatory scrutiny. Majority of the drug-related messages on social media were potentially misleading or false claims that lacked credible evidence to support them. In the public interest, regulatory authorities should monitor such information disseminated via social media platforms.

RESUMO

OBJECTIVES: The aims of this study were to evaluate: (1) the prevalence and types of potentially inappropriate prescribing in older adults with hypertension or diabetes mellitus and hypertension, and (2) whether or not differences in the training of primary care physicians were associated with potentially inappropriate prescribing. MATERIALS AND METHODS: Primary care prescriptions issued by family physicians and general practitioners were audited using Screening Tool of Older Persons' Prescriptions criteria (version 1), with 18 out of 65 applicable criteria. Descriptive statistics were used to test the difference between proportions, and two-tailed t test was used for continuous variables. RESULTS: A total of 2,090 outpatient prescriptions were written during the study period; of these, 712 (34.1%) were potentially inappropriate. The mean number of drugs per patient was 6.03 (±2.5). Of the 712 prescriptions, 543 (76.3%) were used for the treatment of acute medical illnesses. The most common examples of potentially inappropriate prescribing were: orphenadrine (n = 174; 8.33%), long-term nonsteroidal anti-inflammatory drugs for > 3 months (n = 150; 7.18%), proton pump inhibitors for > 8 weeks (n = 135; 6.46%), antihypertensive therapy duplication (n = 59; 2.82%), long-acting glyburide (n = 48; 2.29%), and chlordiazepoxide for > 1 month (n = 44; 2.11%). Family physicians showed a greater tendency toward potentially inappropriate prescribing compared to general practitioners, but the difference was nonsignificant (n = 514 [34.75%] vs. n = 162 [31.3%]; p = 0.16). CONCLUSIONS: The prevalence of potentially inappropriate prescribing (i.e., 34.1%) was within the spectrum reported worldwide and unrelated to the training backgrounds of physicians. Most of the identified potentially inappropriate prescribing (76.3%) in older adults was associated with medications for acute medical illnesses and hence inappropriate polypharmacy should be discouraged.

RESUMO

BACKGROUND: The use of non-steroidal anti-inflammatory drug (NSAIDs) is deemed a major risk factor for peptic ulcer disease in elderly population that requires concomitant therapy with gastroprotective agents (GPAs). OBJECTIVE: This study evaluated the rational prescribing of NSAIDs and GPAs, and extent of adherence to the guideline recommendations in primary care. METHODS: Nationwide audit of prescriptions issued to elderly patients (≥65 years) with hypertension or diabetic hypertension in primary care. RESULTS: Among 2090 elderly, 45.9% were on low-dose aspirin, and 13.5% on other NSAIDs. Diclofenac-XR was the most frequently prescribed NSAIDs to three-quarter patients whereas naproxen, the safest NSAID for patients with high cardiovascular (CV) risk, was rarely prescribed. Among those on NSAID, 82.9% were on a scheduled dosing regimen; of these 78.8% received long-term NSAID therapy (3.9±0.9 months). The prescription rate of GPAs was low: 29.2% for aspirin and 33.3% for other NSAIDs. A quarter of the patients on histamine type-2 receptor antagonists received ranitidine at subtherapeutic single-dose for gastroprotection. Approximately half of the patients on proton pump inhibitors (PPIs) were prescribed supra-therapeutic double-dose regimen: omeprazole and esomeprazole accounted for 63.2% of overall prescribed PPIs. CONCLUSIONS: The rational choice of NSAIDs and physicians' adherence to gastroprotective measures was suboptimal in primary care. The choice of NSAIDs and gastroprotective strategy in elderly be guided by the CV and gastrointestinal adverse events likelihood due to the NSAIDs and risk profile of patients for such adverse events.

RESUMO

BACKGROUND: Inflammatory markers are increased during vaso-occlusive crisis (VOC) in adult patients with sickle cell anemia (SCA), but this is not clear in clinical steady state. AIM: The present study aims to establish the frequency and intensity of bone pain episodes in adult patients with SCA in clinical steady state and to determine the correlation between different inflammatory markers, other variables including QT dispersion (QTd) and pain frequency and intensity in SCA. PATIENTS AND METHODS: Patients were classified into two groups: group 1, those with more than three hospital admissions in the last 6 months, and group 2, those with no hospital admission. Pearson correlation between variables such as body mass index (BMI), level of tumor necrosis factor (TNF-α), interleukin-1 (IL-1), C-reactive protein (CRP), hemoglobin (Hb), reticulocyte count, white blood cell count (WBC), ferritin, lactate dehydrogenase (LDH), parathormone (PTH), vitamin D3 (25-OH cholecalciferol) and bone pain frequency with severity was evaluated. RESULTS: Forty-six patients were enrolled in this study with a mean age of 18.47±5.78 years, with 23 patients in each group. Vitamin D3 and Hb were lower (17.04±5.77 vs 37.59±4.83 ng/L, P<0.01 and 7.96±0.3 vs 8.44±0.27 g/dL, P<0.01, respectively); the inflammatory markers showed significantly higher level of TNF-α, IL-1 and CRP (56.52±5.43 pg/ml, 44.17±4.54 pg/ml and 3.20±0.72 mg/L, respectively, P<0.05); WBC, LDH and reticulocyte count were also significantly higher and the QTd was higher (45.0±2.22 vs 41.55±0.8 ms, P<0.05) in group 1 when compared with group 2. Pearson correlation coefficient showed significant positive correlation between serum level of TNF-α and bone pain frequency (r=0.414, P<0.005) and serum level of IL-1 (r=0.39, P<0.008). CONCLUSION: There is a strong positive correlation between TNF-α, IL-1 and WBC and bone pain frequency in steady state in adult patients with SCA. CRP and low hemoglobin had weak positive correlation. QTd was significantly longer in patients who had hospitalizations with VOC.

RESUMO

OBJECTIVES: This study aimed to explore reasons for poor performance in prescription writing stations of the objective structured practical examination (OSPE) and absenteeism in prescription writing sessions among preclerkship medical students at the Arabian Gulf University (AGU) in Manama, Bahrain. METHODS: This descriptive study was carried out between September 2014 and June 2015 among 157 preclerkship medical students at AGU. Data were collected using focus group discussions and a questionnaire with closed- and open-ended items. RESULTS: All 157 students participated in the study (response rate: 100.0%). The most frequently cited reasons for poor performance in OSPE stations were an inability to select the correct drugs (79.6%), treatment duration (69.4%), drug quantity (69.4%) and drug formulation (68.2%). Additionally, students reported inadequate time for completing the stations (68.8%). During focus group discussions, students reported other reasons for poor performance, including examination stress and the difficulty of the stations. Absenteeism was attributed to the length of each session (55.4%), lack of interest (50.3%), reliance on peers for information (48.4%) and optional attendance policies (47.1%). Repetitive material, large group sessions, unmet student expectations and the proximity of the sessions to summative examinations were also indicated to contribute to absenteeism according to open-ended responses or focus group discussions. CONCLUSION: This study suggests that AGU medical students perform poorly in prescription writing OSPE stations because of inadequate clinical pharmacology knowledge. Participation in prescription writing sessions needs to be enhanced by addressing the concerns identified in this study. Strategies to improve attendance and performance should take into account the learner-teacher relationship.

RESUMO

OBJECTIVES: This study used role-play demonstrations to train medical students to communicate drug therapy and evaluated the perceptions on this instructional approach. MATERIALS AND METHODS: The second-year medical students who attended a prescription writing session (n = 133), participated in this study. Prescription communication was introduced by using role-play demonstrations. Participant's perceptions were explored by a self-administered questionnaire and focus group discussion. The academic achievement of attendees and nonattendees was compared with an objective structured performance evaluation (OSPE) station that tested students' competence in this skill. RESULTS: Most attendees responded to the questionnaire (81.2%). Almost all respondents expressed their desire to have similar demonstrations in other units. A large proportion of participants reported that role-play demonstrations helped them develop their communication skills, in general, confidence to communicate drug-related information in a prescription, and the ability to explain the aim of drug therapy to patients. Most trainees thought also that they developed skills to communicate instructions on drug use including drug dose, frequency of administration, duration of therapy, adverse drug reactions, and warnings. During the focus group interviews, students thought that role-play was useful but would be more beneficial if conducted frequently in small group as part of the curriculum implementation. The majority of students also reported improved competence in writing a complete prescription. Analysis of attendees and nonattendees grades in the OSPE showed that the former scored higher than the latter group (P = 0.016). CONCLUSIONS: Role-play demonstrations were well accepted by medical students and led to the development of their competence in communicating drug therapy to patients.

RESUMO

PURPOSE: Recruitment of tutors to work in problem-based learning (PBL) programs is challenging, especially in that most of them are graduated from discipline-based programs. Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. METHODS: This study included evaluation of faculty (n=69) who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS), Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring) using structured evaluation forms based on a Likert-type scale (poor to excellent). The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. RESULTS: Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000). Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. CONCLUSION: Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

RESUMO

BACKGROUND: Published clinical practice guidelines have addressed antihypertensive therapy and sexual dysfunction (SD) in many different ways. OBJECTIVE: In this systematic review, we evaluated guidelines that address antihypertensive drug-associated SD, guideline recommendations, and recent guideline trends. METHODS: Thirty sets of guidelines for hypertension management in adults that had been published in the English language since 2000 were reviewed. The primary outcome measure was antihypertensive-associated SD potential, which was independently evaluated using specific questions by 2 authors in a nonblinded standardized manner. RESULTS: Sexual dysfunctions associated with thiazide-class diuretics, ß-blockers, and centrally acting sympathoplegics were addressed by half of the guidelines reviewed. There is no clarity on ß-blockers and thiazide-class diuretics because one-third of the guidelines are vague about individual ß-blockers and diuretics, and there is no statement on third-generation ß-blockers and thiazide-like diuretics that can improve erectile function. The revised guidelines never use terms such as loss of libido, ejaculatory dysfunction, lack of orgasm, and priapism. Summary versions of guidelines are inadequate to reflect the key interpretation of the primary guidelines on SD associated with antihypertensives, even in the major guidelines that were updated recently. Therapeutic issues such as exploring SD in clinical history, assessing SD prior to and during treatment with antihypertensives, substituting the offending agents with alternatives that possess a better safety profile, intervening with phosphodiesterase-5 inhibitors, and avoiding the concomitant use of nitrovasodilators are superficially addressed by most guidelines, with the exception of 2013 European Society of Hypertension/European Society of Cardiology and Seventh Joint National Committee recommendations. CONCLUSION: Future guideline revisions, including both full and summary reports, should provide a balanced perspective on antihypertensive-related SD issues to improve the impact of hypertension treatment guidelines on patient care and quality of life.
