RESUMO
Background: Multiple choice questions (MCQs) are a common method for formative and summative assessment of medical students. Item analysis enables identifying good MCQs based on difficulty index (DIF I), discrimination index (DI), distracter efficiency (DE). The objective of this study was to assess the quality of MCQs currently in use in pharmacology by item analysis and develop a MCQ bank with quality items.Methods: This cross-sectional study was conducted in 148 second year MBBS students at NKP Salve institute of medical sciences from January 2018 to August 2018. Forty MCQs twenty each from the two term examination of pharmacology were taken for item analysis A correct response to an item was awarded one mark and each incorrect response was awarded zero. Each item was analyzed using Microsoft excel sheet for three parameters such as DIF I, DI, and DE.Results: In present study mean and standard deviation (SD) for Difficulty index (%) Discrimination index (%) and Distractor efficiency (%) were 64.54±19.63, 0.26±0.16 and 66.54±34.59 respectively. Out of 40 items large number of MCQs has acceptable level of DIF (70%) and good in discriminating higher and lower ability students DI (77.5%). Distractor efficiency related to presence of zero or 1 non-functional distrator (NFD) is 80%.Conclusions: The study showed that item analysis is a valid tool to identify quality items which regularly incorporated can help to develop a very useful, valid and a reliable question bank.
RESUMO
Background: The main objective of this study was to evaluate prescription patterns of antihypertensives in preeclampsia patients at a tertiary care hospital in Central India.Methods: The study belongs to retrospective observational type. he study was conducted by department of Pharmacology in association of department of Obstetrics & Gynaecology department at Nkp Salve Institute of Medical Sciences & Research Centre, Lata Mangeshkar Hospital, Nagpur. Permission from Institute Ethics Committee was taken for studying the prescribing patterns of drugs. The study was conducted for a period of 6 months. Inclusion and Exclusion criteria were added.Results: The maximum number patients seen in age groups 36-41 (28.6%). The main drug prescribed in our study was Labetalol followed by methyldopa. In our study most of the patients were of moderate and mild type corresponding to 48% and 32% respectively and only 20% of patients belong to severe cases. In our study highest number of patients was seen in second gravida i.e. 33.33%.Conclusions: Labetalol was the most common anti hypertensive prescribed in pre eclampsia patients. Rationale prescribing of drugs were done.
RESUMO
Background: Hypertension and diabetes mellitus are both chronic disorders and when they occur as co-morbidities create havoc by presenting with a plethora of morbidity and mortality. Both require drug treatment over a long period of time, which calls for stringent analysis of prescribing trends of the same. Objectives: The present study was intended to analyze prescribing pattern and establish prescribing trends of anti-hypertensive drugs (AHD) in hypertensive diabetic patients. Methods: The present study was a record based, randomized, non-interventional study of 2 years duration conducted at a tertiary care hospital of central India. Prescriptions from 400 case records of hypertensive diabetics were obtained from the medical record section. Demographic details, blood pressure, and AHDs prescribed were systematically entered in pre-validated case record form. All data were thoroughly analyzed for fallacies and appropriateness. Results: Among 400 patients, 221 were males, and 179 were females. Monotherapy was used in 366 (91.5%) patients while combination therapy was used in 34 (8.5%) patients. Most commonly used combination was angiotensin converting enzyme inhibitor (ACEI)+calcium channel blocker (CCB), while in monotherapy CCB≥ACEI>beta blocker>diuretic>angiotensin II receptor blocker were most commonly prescribed. Conclusion: The present study represents trend and attitude of physicians in prescribing AHDs. On comparing with Joint National Committee 7 guidelines, the majority of the cases deviated from the guidelines, mostly in a choice of AHDs and Fixed dose combination.
