Telemedicine: A New Frontier in Clinical Practice.

The COVID-19 pandemic has highlighted the important role of telemedicine as a tool for safe healthcare delivery across the world. While its use was more common in the developed world, the developing world has also adopted this strategy. It is important to develop a clear process and contextual guidance for effective use of this strategy for better patient-doctor interaction and its role in teaching/learning of trainees.

Online assessment in undergraduate medical education: Challenges and solutions from a LMIC university.

BACKGROUND AND OBJECTIVES: The Covid-19 pandemic has caused large-scale disruption in almost all educational programs across the world. Planning and rapid implementation of assessment through an online format presents the next set of novel challenges that must be addressed by academic administrations across the globe. METHODS: This cross-sectional study was conducted between March to August 2020 at the Aga Khan University Medical College. Two hundred medical students of year 1 and 2 participated in the study. We describe the planning, processes, and outcomes of online assessments using video communication platforms conducted at a private university in Pakistan. Standardized protocols were written and piloted, extensive training of student, proctors and staff for preparation and conduct of online assessments were developed. Feedback was recorded after each session and suggestions were incorporated in subsequent high-stakes assessments. RESULTS: A total of three pilot assessments were conducted to identify issues and process refinement. Commercially available lockdown browser and ZOOM were used in the first pilot; 80% of the class was unable to launch lockdown browser and laptops required repeated reload/reboot. For the second pilot assessment, University's VLE page & MS Teams was trailed. Issues with internet connectivity, VLE page slowdown, and suboptimal recording feature in MS Teams were identified. For the final pilot assessment, phased launching of VLE page with single test item per page was implemented with success. The students reported that attempting the online exam on VLE with ZOOM support was user friendly. Ninety percent of the class was supportive of the continuing with the online assessments. CONCLUSION: In order to device an effective protocol for e-assessments conducting multiple trial runs, and incorporating feedback from all stakeholders is a necessity.

Perceptions of technology-enhanced learning in undergraduate medical education at a private medical college in Karachi, Pakistan.

OBJECTIVE: To identify perceptions of key stakeholders in a private medical college for the adoption of technology enhanced learning at the undergraduate level. METHODS: The mixed-method study was conducted at the Aga Khan University Medical College in Karachi from May 2014 to May 2015. Data was collected from students, faculty and academic programme leaders through questionnaires, focus group discussions (FGDs) and semi-structured interviews. SPSS 19 was used for quantitative data analysis. Qualitative data was analysed by generating codes and themes from the FGDs and interview transcripts. RESULTS: There was a consensus among the stakeholders regarding the need to incorporate technology-enhanced learning at the undergraduate level to supplement the curriculum, but not as a replacement for face-to-face class sessions. Students and faculty members have access to technology on campus. Students are appropriately digitally literate and use information and communication technology extensively for studies and other communication needs. All faculty members use PowerPoint and videos, and some use other tools, like simulations. The key challenges to technology-enhanced learning use identified included faculty members' skills to incorporate it in teaching, limited opportunities and time to learn the use of technology, poor faculty incentives for teaching innovation, and lack of availability of technical support and appropriate technologies. CONCLUSIONS: Successful adoption of technology-enhanced learning requires changes in the curriculum and pedagogical approaches, preparedness and willingness of the stakeholders, and academic leaders' vision and support to embrace new teaching and learning approaches.

Effect of faculty personality, rating styles, and learner traits on student assessment in medical education: A mixed-method study from the Aga Khan University, Karachi.

Background: Medical colleges invest considerable effort in developing assessment programs to effectively evaluate students across attributes of knowledge, skills, and behavior. While assessment by direct observation is designed to be objective, "soft characteristics" such as personality, demeanor of student, and assessor may make assessment more subjective. The effect of such attributes in medical education remains unclear and needs exploration. The objective of this study was to explore non-cognitive traits of assessor and learner to understand their roles in student assessment. Methods: A mixed-method study was conducted during March to June 2015. All clinical faculty members at the Aga Khan University were invited to participate in this study. A questionnaire was designed and completed by the study participants. Two focus group discussions (FGDs) with faculty members explored teacher and learner traits influencing student assessment. A documentary analysis of the yearly student feedback report with a focus on the section on assessment was also utilized. Data triangulation was achieved by combining three sets of data. Results: Fifty-four (28%) clinical faculty members completed the questionnaire and 11 participated in the FGDs. About 68% reported rating students leniently. More than 50% reported their personality as a factor influencing assessment and 76% reported student appearance influencing assessment. The documentary analysis identified faculty personality and rating styles as key issues affecting the validity of student assessment during ongoing observation. In the FGDs, traits such as eagerness, intuition in students, and body language were reported to influence faculty members during the assessment. Discussion: Softer attributes of trainer and trainee increase the subjectivity of student assessment. Ongoing faculty training and rater feedback are required for a robust and objective assessment.

Mimicking rashes: Use of moulage technique in undergraduate assessment at the aga khan university, Karachi.

BACKGROUND: The use of simulated patients in student assessment is supported by the Best Evidence Medical Education and U.S. Agency for Healthcare Research and Quality, and it provides a safe and effective alternative to real patients in many situations. To assess the validity and feasibility of moulage technique-where a cosmetically constructed rash is used on simulated patients-two dermatologic rashes were developed using moulage simulation on standardized patients at Aga Khan University Hospital for 3rd year medical summative Objective Structured Clinical Examination (OSCE). METHODS: Checklists for cases that focused on history taking of a skin rash were developed. These also included a description and identification of lesions, differential diagnosis, and basic management. Cases were first reviewed and approved by the Educational Committee and a dermatologist content expert. Stations were piloted to assess validity and feasibility. Simple nontoxic materials were used to develop the rash by faculty familiar with moulage simulation. RESULTS: Sixty-four students were assessed on a Herpes Zoster case and 32 students on a Herpes Simplex case in morning and afternoon sessions. The total mean score obtained at all OSCE stations was 64.82 ± 10.22. Mean scores on the morning and afternoon dermatology stations were 62.72 ± 9.74 and 69.03 ± 9.98, respectively. Face validity for both stations was established through input of content experts. The internal reliability as measured by Cronbach's alpha between the checklist items on the morning and afternoon stations was acceptable at 0.60 (20 items) and 0.65 (18 items), respectively. DISCUSSION: The use of moulage technique to develop dermatologic lesions on simulated patients may be utilized for student assessment.

Health literacy in Pakistan: Exploring new ways of addressing an old challenge.

Pakistan continues to struggle with low health literacy that often results in late presentation of disease, poor adherence to treatment and meagre understanding of wellness and disease prevention. In a country burdened by diseases of the developing and the developed world, with poor healthcare infrastructure and low literacy levels improving healthcare literacy could have major influence on health and wellness of our masses. Utilising our rapidly expanding mobile technology and media for dissemination of health information is a viable solution. Public service announcements for media and health information apps for mobile technology can be developed by the government, health sector and media partnership. A systematic, multi-level targeted approach to health literacy would allow health seekers the opportunity to understand and comprehend disease prevention, symptomatology and treatment.

The case for family medicine in Pakistan.

The specialty of Family Medicine enjoys a special position in the medical practice of the West, serving as one of the key primary care specialties. Family physicians act as providers of first contact catering to the medical needs of the entire family in all aspects of preventive, curative and rehabilitative stages of illness and to health maintenance. The growth of this specialty, however, has lagged behind in Pakistan for various reasons. Having both a high burden of communicable and non-communicable diseases in Pakistan; family physicians should form the frontline force in dealing with these health issues. Several success stories of Family Medicine forming the base of medical services have been noted, validating its presence and propagation. The World Health Organisation also supported this in its 2008 report that discusses primary care for all. Growth of family practice needs to be encouraged at both undergraduate and postgraduate levels to ensure adequate training and provision of quality of medical care to our society. The need of the hour is that both medical institutions and the government develop policies to strengthen Family Medicine and incentivise family practice in rural and urban settings to cater to the needs of society at large.

Isoniazid induced motor-dominant neuropathy.

Isoniazid though a very effective treatment for tuberculosis can cause severe motor-dominant neuropathy which can be reversible with pyridoxine supplementation. A 45-year-old female diagnosed with psoas abscess, culture positive for mycobacterium tuberculosis, was started on anti- tuberculous treatment with four drugs, including isoniazid at a dose of 5 mg/kg/day. Three months later she developed severe motor weakness of lower limbs with loss of ankle and knee reflexes. She was treated with vitamin B6 injections and isoniazid treatment was continued. Her motor weakness gradually improved in a few months, but mild sensory impairment persisted even after two years. There is need for vigilance regarding neurological effects of isoniazid in seemingly low-risk individuals in whom development of symptoms should raise the suspicion about slow acetylator status. Timely therapeutic intervention with high-dose vitamin B6 can reduce the long-term morbidity associated with this easily reversible condition.

Polypharmacy in elderly: a cautious trail to tread.

Polypharmacy has now increasingly come into focus as the recipient of healthcare in old age worldwide. In elderly it is associated with frequent adverse drug reactions (ADRs) and drug-drug interactions resulting in significant morbidity. Geriatrics is still an emerging specialty in South Asia, especially in Pakistan, where multiple reasons for polypharmacy exist. An extensive literature review of articles using key words like 'polypharmacy,' 'elderly' was conducted. The recently updated Beers Criteria of classification of inappropriate drugs in the elderly was reviewed in detail. Articles of relevance to polypharmacy and evaluation of guidelines for appropriate interventions to minimise inappropriate drug prescribing were also reviewed. Commonly prescribed drugs like psychotropic, cardiovascular, nonsteroidal anti-inflamanatory drugs (NSAIDs) and oral hypoglycaemics can cause significant adverse events when prescribed to the elderly. Primary care physicians may use evidence based non-pharmacological interventions which may be appropriate to use in selected cases. Drugs can affect quality of life and morbidity in the elderly. A basic understanding of ageing physiology and pharmacology along with a step-wise approach to prescribing in the elderly maybe helpful in minimising iatrogenic complications of commonly used drugs in this age group.

Creation of Virtual Patients for Undergraduate and Postgraduate Medical Education: An Experience from Pakistan.

OBJECTIVE: To create virtual patients as an educational tool to determine their feasibility and effectiveness in clinical problem solving. STUDY DESIGN: Cross-sectional study. Place and Duration of the Study: The Aga Khan University Hospital, Karachi, from 2018 to 2021. METHODOLOGY: Prototype virtual patients were developed at the Aga Khan University Hospital, Karachi, for medical trainees. Articulate Storyline 360 software was used for creating clinical encounters. Undergraduate students and postgraduate trainees were selected using purposive sampling to practice on these virtual patients (VPs). They were asked to provide feedback on the construction and usefulness of virtual patients as a learning modality. RESULTS: Two VPs were created and used. The geriatric VP was used for the assessment of final-year students. Twenty-five students gave detailed feedback after completion. Most (90%) agreed that the VP provided realistic scenarios and improved clinical reasoning. Almost five identified the need to improve navigational instructions. The pediatric VP for postgraduate trainees was well received. Almost 90% reported that it facilitated learning and improved knowledge and clinical reasoning. There was a 30% increase in post-test scores, supporting it as an adjunct resource for clinical learning. CONCLUSION: Virtual patients can be easily created using local disease patterns to make learning more contextual. They enhance clinical reasoning and decision-making in a safe learning environment.   Key Words: Medical education, Virtual patients, e-learning.

Recurrent Hypoglycaemia In An Older Individual With Covid-19.

Coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged as a deadly pandemic overburdening healthcare system globally. While people of all ages were affected, the older population has faced disproportionately higher morbidity and mortality, likely due to altered immune responses and pre-existing comorbid conditions like cardiovascular disease, hypertension, diabetes mellitus, chronic pulmonary and kidney disease. Clinical manifestations in older patients may also be atypical with absence of fever, increased chances of acute confusion and longer recovery times. While other parameters of disease severity have been found, poor glycaemic control is another indicator of severity in COVID 19 infection. Moreover, older patients with diabetes mellitus are also at risk of hypoglycaemia which increases the risk of cardiovascular and cerebrovascular events, progression of dementia, falls, emergency department visits and hospitalization. Here we share a case of an older man with COVID-19 infection who presented primarily with recurrent hypoglycaemia and weakness. This case also highlights the social impact of an infection that has decimated support systems for vulnerable older adults.

Feasibility and Effectiveness of Mini-Clinical Evaluation Exercise (Mini-CEX) in an Undergraduate Medical Program: A Study From Pakistan.

Background In clinical settings, direct observation (DO) with feedback is an effective method to assess and improve learner performance. One tool used for DO is the mini-clinical evaluation exercise (Mini-CEX). We conducted a study to assess the effectiveness and feasibility of Mini-CEX for medical students at Aga Khan University, Karachi. Methods Utilizing a purposive sampling technique, a total of 199 students in six core clerkships of Years 3 and 4 were selected for this study. Participating faculty underwent training workshops for use of Mini-CEX and feedback strategies. Each student was assessed twice by one faculty, using a modified version of the Mini-CEX, which assessed four domains of clinical skills: Data Gathering, Communication, Diagnosis/Differential, and Management Plan and Organization. Feedback was given after each encounter. Faculty and students also provided detailed feedback regarding the process of DO. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 26 (IBM Corp., Armonk, NY, USA), with categorical variables arranged as frequencies and percentages. The Chi-squared test was used for further statistical analyses, and a P-value of < 0.05 was considered statistically significant. Effectiveness was assessed via a change in student performance between the first and second Mini-CEX, and feasibility was assessed via qualitative feedback. Results We obtained three sets of results: Mini-CEX forms (523), from which we included a total 350 evaluations for analysis, 216 from Year 3 and 134 from Year 4, and feedback on DO: student (70) and faculty (18). Year 3 students performed significantly better in all foci of the Mini-CEX between the first and second assessment (P ≤ 0.001), whereas in Year 4, significant improvement was limited to only two domains of the Mini-CEX [Communication of History/Physical Examination (P = 0.040) and Diagnosis/Differential and Management Plan (P < 0.001)]. Students (65.7%) and faculty (94.4%) felt this exercise improved their interaction. 83.3% faculty recommended its formal implementation compared to 27.1% of students, who reported challenges in implementation of the Mini-CEX such as time constraints, logistics, the subjectivity of assessment, and varying interest by faculty. Conclusion Direct observation using Mini-CEX is effective in improving the clinical and diagnostic skills of medical students and strengthens student-faculty interaction. While challenges exist in its implementation, the strategic placement of Mini-CEX may enhance its utility in measuring student competency.

Comparison of exhaled carbon monoxide levels among commuters and roadside vendors in an urban and a suburban population in Pakistan.

Carbon monoxide (CO) is one of the six criteria air pollutants related to urbanization and has a wide range of health effects. The study measured and compared the exhaled CO levels among commuters and roadside vendors in potentially heavy and low traffic volume areas of Karachi, a megacity in Pakistan. Saddar town [areas of M. A. Jinnah Road (Tibet Center, Denso Hall) and Empress Market] was selected to represent an area of high traffic volume and the suburban town of Gadap (Gadap and Gulshan-e-Maymar) was selected to represent an area of no or low traffic volume. The study compared the CO exposure of commuters and roadside vendors in high and low traffic volume in Karachi. CO exposure was measured in expired air using the breath analyzer module of Bacharach Monoxor-II, USA. A total of 326 individuals (115 commuters and 211 stationary roadside vendors) from Saddar town (n = 193) and Gadap town (n = 133) were selected. In addition, CO levels in ambient air in the same areas, using portable CO analyzer (Bacharach, Monoxor-II, USA), were measured. The mean ambient CO level at Saddar town was 15.6 (SE ± 2.6) ppm compared to 3.3 (SE ± 0.3) ppm at Gadap town. The mean CO level in expired air was significantly higher among nonsmokers at Saddar town (12.8 ± 0.5 ppm) compared to the nonsmokers at Gadap town (7.8 ± 0.4 ppm). The mean CO level in expired air among smokers was twice that of nonsmokers (21.6 vs. 10.6 ppm). CO in expired air was greater among high traffic volume commuters and roadside stationary population in Karachi, Pakistan. The population in Karachi is exposed to high concentration of air pollutants. These pollutants need to be characterized for health effects and interventions needs to be developed.

Effectiveness of Simulation-based Clinical Skills Training for Medical Students in Respiratory Medicine: A Pilot Study.

OBJECTIVE: To assess the effectiveness of high-fidelity simulation-based medical education (HF-SBME) in teaching and learning respiratory clinical examination in medical students. STUDY DESIGN: Quasi-experimental pilot study. PLACE AND DURATION OF STUDY: The Aga Khan University, Karachi, from November 2018 to January 2020.   Methodology: This study was conducted amongst third year medical students at the University. Students were assigned to intervention (IG) or control groups (CG). The IG underwent training for the respiratory clinical examination on a high-fidelity simulator mannequin, while the CG received the conventional practice session on standardised patients. Students were assessed on their respiratory clinical examination skills in five domains, and each domain was scored between 1-3 points (poor=1, fair=2, good=3) for a maximum composite score of 15. Feedback on use of SBME was also obtained from students. RESULTS: There were no statistically significant differences in demographics for the CG (n=41) and IG (n=40). Composite score for control and intervention groups was not significantly different (CG: 12.9 ± 1.89 vs. IG: 12.0 ± 2.35; p=0.067). However, a greater percentage of CG students were rated good in all five domains, with the difference being statistically significant for ability to correlate findings with clinical history (CG: 87.8% vs. IG: 67.5%; p=0.028). CONCLUSION: Although medical students perceived HF-SBME as a beneficial teaching modality, it did not translate into improved performance. More research is required to determine the utility of HF-SBME in a developing country, like Pakistan. Key Words: Simulation, High-fidelity, Medical education, Developing country, Clinical skills.

Elderly musculoskeletal disease burden in Karachi, Pakistan: Associations and implications for developing countries.

OBJECTIVE: The global rise in the older population has increased the rates of osteoporosis and osteoarthritis, conditions that impact mobility and functionality. There is limited data on musculoskeletal disease in older populations residing in developing countries. METHODS: A community-based study using multistage cluster random sampling of older individuals was conducted in Karachi. Predefined criteria were used for osteoporosis and osteoarthritis. Gait assessment was performed. RESULTS: More than half of the participants were females and 53% reported illiteracy. Around 30% had osteoporosis and two-thirds had osteoarthritis. Multivariate analysis showed associations of female sex, Pashtun ethnicity, illiteracy, and hypertension with the combined variable of osteoporosis and osteoarthritis. CONCLUSIONS: The prevalence of osteoarthritis was higher than in other regional studies. Presence of both osteoporosis and osteoarthritis increased the risk of certain geriatric syndromes. High rates of musculoskeletal morbidity are seen in the elderly in Pakistan. Measures at a health-system level are required for better outcomes in older adults.

A living WHO guideline on drugs to prevent covid-19.

CLINICAL QUESTION: What is the role of drugs in preventing covid-19? WHY DOES THIS MATTER?: There is widespread interest in whether drug interventions can be used for the prevention of covid-19, but there is uncertainty about which drugs, if any, are effective. The first version of this living guideline focuses on the evidence for hydroxychloroquine. Subsequent updates will cover other drugs being investigated for their role in the prevention of covid-19. RECOMMENDATION: The guideline development panel made a strong recommendation against the use of hydroxychloroquine for individuals who do not have covid-19 (high certainty). HOW THIS GUIDELINE WAS CREATED: This living guideline is from the World Health Organization (WHO) and provides up to date covid-19 guidance to inform policy and practice worldwide. Magic Evidence Ecosystem Foundation (MAGIC) provided methodological support. A living systematic review with network analysis informed the recommendations. An international guideline development panel of content experts, clinicians, patients, an ethicist and methodologists produced recommendations following standards for trustworthy guideline development using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. UNDERSTANDING THE NEW RECOMMENDATION: The linked systematic review and network meta-analysis (6 trials and 6059 participants) found that hydroxychloroquine had a small or no effect on mortality and admission to hospital (high certainty evidence). There was a small or no effect on laboratory confirmed SARS-CoV-2 infection (moderate certainty evidence) but probably increased adverse events leading to discontinuation (moderate certainty evidence). The panel judged that almost all people would not consider this drug worthwhile. In addition, the panel decided that contextual factors such as resources, feasibility, acceptability, and equity for countries and healthcare systems were unlikely to alter the recommendation. The panel considers that this drug is no longer a research priority and that resources should rather be oriented to evaluate other more promising drugs to prevent covid-19. UPDATES: This is a living guideline. New recommendations will be published in this article and signposted by update notices to this guideline. READERS NOTE: This is the first version of the living guideline for drugs to prevent covid-19. It complements the WHO living guideline on drugs to treat covid-19. When citing this article, please consider adding the update number and date of access for clarity.

Effectiveness of home-based rehabilitation program in minimizing disability and secondary falls after a hip fracture: Protocol for a randomized controlled trial.

INTRODUCTION: Hip fractures are a major health problem globally and are associated with increased morbidity, mortality, and substantial economic costs. Successful operative treatment of hip fracture patients is necessary for the optimization of post-op mobility and functional recovery of the patient. Rehabilitation after surgical stabilization of a hip fracture is crucial in order to restore pre-fracture function and to avoid long-term institutionalization. In particular ongoing exercise which targets balance can prevent up to 40% of falls. Therefore, we have designed a post-discharge home-based physical rehabilitation intervention program to minimize disability and falls in this high-risk elderly population. METHODS AND ANALYSIS: The study will be an open label, simple randomized controlled trial at a single hospital. The two arms will be equally allocated on a 1:1 ratio into intervention and control groups. The control arm will receive the usual standard postoperative rehabilitation. The intervention group will receive an extended home-based rehabilitation program twice a week continued for 3 months (12 weeks) after discharge. The Primary outcome of the study is occurrence of falls. Falls will be measured at 3, 6, 12, and 24 months by research-assistant follow-up telephone calls for both the groups. Mobility-related disability will be measured with a self-reported test at every routine follow-up for up to two years using a performance-based short battery tool. Negative binomial regression model will be used to compare number of falls in both the groups by computing incidence ratio rates. ETHICS AND DISSEMINATION: Approval for the conduction of this study has been taken from the Ethical Review Committee (ERC) of the institution. Evidences which will be obtained from this study will facilitate to propose changes in existing guidelines and policies for treating fall and hip fracture patients.Trial registrationThis trial is registered on clinicaltrials.gov ID: NCT04108793.

Experiences, attitudes and barriers towards research amongst junior faculty of Pakistani medical universities.

BACKGROUND: The developing world has had limited quality research and in Pakistan, research is still in its infancy. We conducted a study to assess the proportion of junior faculty involved in research to highlight their attitude towards research, and identify the factors associated with their research involvement. METHODS: A cross-sectional study was conducted in four medical universities/teaching hospitals in Pakistan, representing private and public sectors. A pre-tested, self-administered questionnaire was used to collect information from 176 junior faculty members of studied universities/hospitals. Logistic regression analysis was used to identify factors related to attitudes and barriers in research among those currently involved in research with those who were not. RESULTS: Overall, 41.5% of study subjects were currently involved in research. A highly significant factor associated with current research involvement was research training during the post-graduate period (p < 0.001). Other factors associated with current involvement in research were male gender, working in the public sector and previous involvement in research. Overall, a large majority (85.2%) of doctors considered research helpful in their profession and had a positive attitude towards research; nevertheless this positive attitude was more frequently reported by doctors who were currently involved in research compared to those who were not (OR = 4.69; 95% CI = 1.54-14.26). Similarly, a large proportion (83.5%) of doctors considered research difficult to conduct; higher by doctors who were not presently involved in research (OR = 2.74; 95% CI = 1.20-6.22) CONCLUSION: Less than half of the study participants were currently involved in research. Research output may improve if identified barriers are rectified. Further studies are recommended in this area.
