PERCEPTION OF FIRST YEAR MBBS STUDENTS TOWARDS ECE (EARLY CLINICAL EXPOSURE) IN PHYSIOLOGY.

Introduction : Early Clinical Exposure is a teaching learning method which enables student to learn basic sciences effectively and retain the information which bene?ts patient and promotes better patient care. Hundred students selected after applying inclusion exclusion criteria divided into 2 groups A and B taught Methodology : basal ganglia and thyroid physiology in conventional method and other in ECE integrated method respectively and after interchanging groups, demonstrating the clinical features of parkinsonism and hypothyroidism for ECE group. A pretest and post-test were conducted preceding and following lecture in both settings. The results obtained were interpreted using Results : excel. The mean of pre-test marks for Traditional teaching and ECE integrated teaching are 5.62±2.42 and 4.58±2.33 respectively and the post-test scores of Traditional and ECE teaching are 10.62±2.52 and 12.8±2.46 respectively. Discussion : Majority considered that the synchronisation of classroom learning with clinical experiences was bene?cial, and the majority believed that integrated teaching improved understanding of the practical applications of physiology. Through Conclusion : this study we conclude that ECE integrated teaching is more effective in imparting knowledge in ?rst MBBS students as the gap of imagination was bridged by live demonstration with help of patient which is re?ected in the Likert scale and in the scores. Though the ECE integration is a tough job for the teacher, it is a great learning tool for students.

Effectiveness of self-directed learning in physiology-students’ perspective

Background: Self-directed learning (SDL) is an important adult learning educational approach where the learner makes all the effort to study on his own with or without the help of a facilitator. SDL gives the learner greater autonomy and freedom over his own learning process. Aim and Objectives: (1) To compare lecture-based and SDL methodologies using pre-test and post-test on 1st year MBBS students in physiology. (2) To know the effectiveness of SDL methodology sessions from a student’s perspective using questionnaires. Materials and Methods: The present study was conducted among 1st year MBBS students in the Department of Physiology. After taking ethical clearance from the institutional ethical committee, total of 150 students were divided into two groups comprising 75 each. Each group attended two sessions of SDL and lecture where pre-test and post-test was given in the form of MCQs. Pre-test and post-test scores of each session were compared. Student’s perspectives about SDL were assessed via questionnaires. Data entry and analysis were carried out using Microsoft excel datasheet and SPSS software (Ver. 22). The test of significance for paired data was done using Wilcoxon Signed rank test. Results: In our study, it was found that the mean value of the post-test scores of SDL group were greater than that of the lecture session. Majority of students perceived the SDL sessions to be more effective. It helped them know their objectives and proactively establish their learning goal. Conclusion: SDL sessions are more effective than lecture sessions in teaching physiology to 1st year MBBS students. It ensures that the learner becomes more independent, which is a highly desirable trait for a medical graduate.

Considering the probable differential diagnosis

@#Differential diagnosis is the method of limiting the possible causes of the patient’s symptoms before making a final diagnosis. For experienced clinicians, it is the process of using clinical experience alongside the patient’s symptoms and test results to prioritize the list of possibilities until the diagnosis can be identified with confidence.

Introduction: Knowledge about falls prevention is essential in reducing incidence in the elderly; nursing intervention may be the way for achieving it. Objective: To assess a Jean Watson's model-based nursing intervention's effectiveness in the level of knowledge about falls prevention in the elderly who have experienced it. Methods: Quantitative and pre-experimental research with pre-test and post-test, contextualized in 37 family medical offices belonging to Dr. Rudesindo Antonio García del Rijo Polyclinic (Sancti Spíritus Province, Cuba), and carried out from 2018 to 2019. The universe was made up of 42 elderly people who had falls in the last year. Knowledge was measured with surveys validated by experts and piloting with Cronbach's alpha higher than 0.5. For the thematic and methodological axes of the intervention (based on the ten care factors of Jean Watson's theory), the bibliography on the subject was reviewed, as well as the identified knowledge needs were taken into account. The information was processed with absolute frequencies, percentages, mean, standard deviation, as well as with minimum and maximum value. The Wilcoxon's signed rank test was used to test the hypothesis. Results: Prior to the intervention, level four of knowledge was shown by 9.52 percent of the elderly. Once the intervention was applied, it amounted to 90.47 percent, with significance of -5.249 and P < 0.05. Conclusions: A nursing intervention based on Jean Watson's model was effective in increasing the level of knowledge about falls prevention in the elderly who have experienced it(AU)

Assessment of training need and training efficacy for national program for prevention and control of cancer, diabetes, cardiovascular diseases and stroke among medical officers of West Bengal, India

Background: The national program for prevention and control of cancer, diabetes, cardiovascular diseases and stroke (NPCDCS) has been rolled out in West Bengal, with its implementation initiated through state-wide training of Medical Officers (M.O). For attaining requisite competency for meeting NPCDCS objectives, MOs have been trained at their respective district levels. Present study aimed to assess the training need, training efficacy and need for further training.Methods: A repeat cross-sectional study was conducted from May-July 2018 for M.Os of six randomly chosen districts of West Bengal, out of those whereat NPCDCS was launched in first phase. 40-45 M.Os were randomly selected from each district in liaison with district level health authorities. The total sample size was 352 with Finite population correction. On the days of training, pre and post training surveys were conducted with an identical semi-structured, pre-tested and validated questionnaire (Cronbach’s alpha >0.8) covering different levels of cognitive domain, with a maximum possible score of 100 marks. No negative marking was done for incorrect responses. Training was imparted by the Principal Investigator (accredited trainer). Ethical clearance was granted by the State Health Directorate. Informed consent from each participant was obtained.Results: Dependent sample t-test revealed significant increment (p<0.0001) in post-test scores (t=63.134) & one-way repeated measure general linear model (GLM) also revealed F=29.617 (p<.0001). The “Effect Size” was classified as “Huge” (Cohen’s D=63.134/√(352)= 3.365), as was noted between pre-test and post-test scores, based on Cohen’s convention and Sawilowsky’s addition. It was further noted that even after six hour training sessions there was 27.44% knowledge gap (p<0.0001) after adjusting for Bonferroni.Conclusions: Imperativeness of training coupled with periodic refresher training has been established as a pre-requisite for successful implementation of NPCDCS.

A study to assess the effectiveness of training on first aid among students of industrial training institute in tribal area of Thane district, Maharashtra

Background: Sudden illness, injury or animal bites can often be serious unless proper care is administered promptly. First aid is immediate attention to one suffering from illness or injury. Everyone should be able to give effective assistance until an injured person can receive professional medical care. This study was undertaken with objectives of assessing the baseline knowledge among students of industrial training institute (ITI) about common health emergencies, their appropriate first aid measures and to conduct training on first aid through lecture and demonstration as well as to assess effectiveness of training on their knowledge about first aid.Methods: An Interventional study. Baseline and post-test assessment of knowledge scores was carried out after a week and 16 weeks of training sessions on first aid of all students in the institute. Data analyzed by SPSS software using descriptive statistics and appropriate statistical tests of significance.Results: Baseline knowledge about first aid in injuries and bites was higher among students than their knowledge about burns and other emergencies. Rural students and students of scheduled caste and tribe had low baseline knowledge (p=0.015 and p=0.025 respectively). Training on first aid significantly improved knowledge about all health emergencies among all students as evident from post-test scores at first week and 16 weeks (p<0.05). Gain in knowledge was significantly higher among rural students.Conclusions: Students had low baseline knowledge about first aid measures. Sessions combining knowledge and skills have brought about significant improvement in the knowledge of participants irrespective of their age, caste or urban-rural background.

Diagnostic models of the pre-test probability of stable coronary artery disease: A systematic review

A comprehensive search of PubMed and Embase was performed in January 2015 to examine the available literature on validated diagnostic models of the pre-test probability of stable coronary artery disease and to describe the characteristics of the models. Studies that were designed to develop and validate diagnostic models of pre-test probability for stable coronary artery disease were included. Data regarding baseline patient characteristics, procedural characteristics, modeling methods, metrics of model performance, risk of bias, and clinical usefulness were extracted. Ten studies involving the development of 12 models and two studies focusing on external validation were identified. Seven models were validated internally, and seven models were validated externally. Discrimination varied between studies that were validated internally (C statistic 0.66-0.81) and externally (0.49-0.87). Only one study presented reclassification indices. The majority of better performing models included sex, age, symptoms, diabetes, smoking, and hyperlipidemia as variables. Only two diagnostic models evaluated the effects on clinical decision making processes or patient outcomes. Most diagnostic models of the pre-test probability of stable coronary artery disease have had modest success, and very few present data regarding the effects of these models on clinical decision making processes or patient outcomes.

Assessment on antibody test for diagnosis performance of heparin induced thrombocytopenia / 临床检验杂志

Objective To assess the antibody test for the diagnosis performance of heparin induced thrombocytopenia(HIT).Methods 52 plasma samples of patients with HIT,126 plasma samples of heparin treated patients without HIT and 50 plasma samples of healthy individuals were collected from 2014 September to 2016 November.According to thrombosis,the patients were further divided into two groups:isolated HIT group without thrombosis (30 cases) and heparin induced thrombocytopenia with thrombosis (HITY) group (22 cases).The whole HIT antibody in plasma was assayed by using ACL-TOP 700 coagulation analyzer and reagent (HemosIL HIT-AbPF4-H).The IgG-specific HIT antibody in plasma was assayed by using ACL AcuStar chemiluminescent analyzer and reagent (HemosIL AcuStar HIT-IgGPF4-H).Results The levels of whole antibody and IgG-specific antibody in the patients of heparin control group was higher than those in healthy control (U value was 1 644.0 and 1 911.0,respectively,P ＜ 0.01).The levels of two HIT antibodies in HIT patients group were higher than those in the patients of heparin control group (U value was 550.0 and 4.7,respectively,P ＜ 0.01).ROC curve showed that the sensitivities of both whole antibody and IgG-specific antibody were 100％,and up-regulating the cut-off value could improve the specificity of both tests.The positive incidence of the whole antibody was 27.8％ in the heparin control group and 100％ in HIT patients group while the cut-off value was 1.50 U/mL.The positive incidence of IgG-specific antibody was 0 in the heparin control group and 100％ in the HIT patients group while the cut-off value was 1.51 U/mL.While the cut-off value of IgG-specific antibody was 2.32 U/mL,the diagnosis sensitivity of thrombosis assessment was 90.9％ and the specificity was 80.0％.In case the cut-off value exceeded 2.32 U/mL,the accumulating risk of HIT increased significantly in HIT patients within 15 days (Log-rank x2 =56.577,P ＜ 0.01).Conclusion The whole antibody and IgG-specific antibody could contribute to excluding diagnosis,diagnosis or risk assessment for the suspected HIT patients.

Questionnaire based assessment of teaching effectiveness during a lecture series on pharmacotherapeutics.

Background: Lecture is a widely accepted method of teaching & learning. It provides more of surface learning and covers larger text in specified time. However it has a disadvantage that there is no assessment about the extent of knowledge learner receives. Hence, we designed a daily questionnaire based evaluation technique. Methods: Without disclosing the topic, second year MBBS students (mean n=23) after learning from lecture series in Pharmacology, participated voluntarily to a questionnaire based task on eight therapeutic lecture topics. They wrote answers separately in 5-10 minutes before, and after delivery of text without referring to notes i. e. pre-test & post-test. Papers were valued on score basis, data recorded, interpreted and analyzed. Results: Mean acceptability (81.4%), mean improvement (94%), mean collective maximum score (96%), mean individual maximum score (92%) were observed. 85-100% participants out of total 184 in eight therapeutic lecture topics passed in post-test (None passing in Pre-test) reflected good improvement in cognitive structure. Conclusion: Performance in such tests provides feedback on teaching effectiveness, specificity & adequacy of knowledge gained by learners.

Optimizing the Effectiveness of CME Program: NAMS Experience.

Planning organisation and delivery of educational program(s), culminating in purposeful learning require strong basis of principles of adult learning along with a sound knowledge and requisite skills in both psychology as well as technology of medical education. Assessing effectiveness of a CME program is as important as the organization of learning activities and delivery of academic program as these may provide further directions for enhancing the efficacy of the CME delivery system. Objective: (i) The purpose of this study was to investigate the effectiveness of well planned and conducted CME program in terms of enhancing knowledge and competence of the participants. (ii) To explore if the gain in knowledge and competence, if any, can be attributed to the interactive design of the educational process. Methods: The study was conducted during NAMS-AIIMS Regional Symposium on Sleep Medicine at AIIMS, Jodhpur as part of NAMSCON 2013. After explaining the objectives of the study to the participants and assurance of confidentiality, a validated and pre-tested questionnaire consisting of 30 multiple choice, single response questions, was administered to 103 participants. Following intervention consisting of didactic lectures by experts in different aspects of sleep medicine, interactive sessions and problem triggered sessions consisting of clinical data, participants were readministered post test questions which were, however, different from pre-test but had similar difficulty level. Result: The response rate of participants was 89%. Pre-intervention scores were 11.76 ± 4.4, with only 26 % of participants achieving an arbitrary pass score of 50 %. Comparison of paired score of participants who attempted both pre and post tests (n=59) showed improvement from 12.1 ±4.6 to 18.3 ± 3.8 which was significant (p <0.05). 84.7 % of participants secured above pre decided 50% score. The mean increase in the score was 6.2 with 95% CIs 4.8; 7.5 (P <0.001). Higher gain in knowledge and competencies is attributed to intense interactive involvement of participants during the problem triggered sessions, feedback provided during interaction and system of reward and incentive introduced at time of sessions. The study concludes that well designed educational intervention based on the principles of adult learning brings positive gain in the knowledge and enhances competence of the participants.

Evaluation of “Palliative care workshop for physicians engaged in clinical practice for cancer treatment held in Kyoto”

In Kyoto, we held the first “Palliative care workshop for physicians engaged in clinical practice for cancer treatment” in Japan on June 7-8, 2008 under the directive of the Ministry of Health, Labor and Welfare. There were 163 participants in the workshop, including 56 physicians and 107 voluntarily participating healthcare professionals (77 nurses, 23 pharmacists and 7 other medical professionals). We analyzed the results of tests consisting of 25 questions classified into 7 categories based on their contents. Tests were administered before and after the workshop (pre-test and post-test), and the educational effects of our conference were evaluated by examining changes in test scores. Participants other than physicians, nurses and pharmacists were excluded from analysis of the test scores because comprehensive medical knowledge was required to solve the questions. The mean rates of correct answers on pre- and post-test were 87.9% for physicians (total 78.9%) and 94.6% for physicians (total 89.1%), respectively. The scores were markedly increased after the workshop, showing practical significance of our attempt. However, the percentage of correct answers regarding psychological symptoms was lowest for physicians as well as for other healthcare professionals on both pre- and post-test. These findings strongly suggest that the workshops produced a sufficient educational effect, but improvement in individual training systems is considered necessary, especially in fields related to psychological manifestations.

Pre-Test Likelihood, Experience of Operators and Additive Diagnostic Efficacy of Gated Attenuation-Corrected Myocardial SPECT in coronary Artery disease

BACKGROUND AND OBJECTIVES: We investigated if gated and/or attenuation-corrected SPECT improved performance of experienced or in-experienced operators in the diagnosis of coronary artery disease (CAD) or stenosed arteries in patients having intermediate or high pretest likelihood. MATERIALS AND METHODS: Rest/dipyridamole stress gated attenuation-corrected SPECT was performed in 81 patients (M:F=48:33, 62+/-8.6 years old, of high (n=38) or intermediate (n=43) pre-test likelihood for CAD, 1 vessel; 14, 2 vessel; 19, 3 vessel disease; 31, normal; 17). Two experienced and one novice physicians graded 1 (normal) to 5 (definitely abnormal) for each artery 1) by conventional rest Tl-201/stress Tc-99m-MIBI SPECT, 2) 1) plus viewing gated SPECT (+gated) and 3) 2) plus attenuation-corrected SPECT (+AC gated). Areas under curves (AUC) of receiver operating characteristic (ROC) curves were compared. RESULTS: AUC was greater in patients with high likelihood than intermediate likelihood. Novice physician performed better in diagnosing RCA stenosis (AUC: 0.53 for usual, 0.58 for +gated, and 0.66 for +AC gated) in patients with intermediate likelihood. AUC was not different for the diagnosis of CAD and LAD or LCx. Performance of experienced physicians was not different regardless of pre-test likelihood. Novice operator's specificity increased from 53% to 73% for CAD, and 62% to 89% (p<0.05) for RCA in patients with intermediate likelihood. CONCLUSION: We conclude that gated attenuation-corrected SPECT was helpful only for novice physician to diagnose RCA stenosis by increasing specificity in patients with intermediate likelihood. Even for inexperienced physician, these methods were not helpful in patients with high pre-test likelihood or for LAD or LCX.
