ABSTRACT

BACKGROUND: A substantial number of older adults succumb soon after HIV diagnosis despite ART. We explored the causes, risk factors and circumstances before death among older adults acquring HIV. METHODS: We recruited individuals newly diagnosed at our centre from 2016-2020 and analysed data of those who died. Patients were stratified to older (≥50 years) or younger (<50 years) based on their age at diagnosis and attributes were compared. The Cox proportional multivariable model was used to identify factors associated with all-cause mortality. RESULTS: Among 75 deaths reported, the majority of deaths were AIDS-related and late presentation was common in both age groups. The majority of deaths occurred in the first 12 months after care presentation and over two-thirds in both groups disengaged from care prior to death. Older age remained an independent factor associated with death after adjusting for confounders including opportunistic infections, late presentation to care, ART initiation and chronic comorbidities at presentation. CONCLUSION: Most causes of death in our setting were AIDS-related and associated with late care presentation both in young and older individuals, although older age at diagnosis remained an independent risk factor. Our findings highlight the urgent need to encourage prompt ART initiation following diagnosis, especially in older adults.

ABSTRACT

The proportion of new HIV diagnoses among older adults aged ≥50 years continues to rise. Older adults are at higher risk of late diagnosis which is associated with higher treatment complexity and poorer health outcomes. Few studies in the Asia-Pacific region have explored factors contributing to late presentation and diagnosis in this population. Thus, our study aimed to explore factors influencing late HIV diagnosis among older adults ≥50 years in Malaysia. We conducted in-depth interviews with 16 older adults newly diagnosed with HIV (OPLWH) and focus group discussions with seven healthcare providers (HCPs) from different specialties in an academic tertiary hospital in Malaysia. All sessions were audio-recorded, transcribed verbatim and analysed thematically. Three main themes related to late diagnosis among OPLWH emerged: (1) challenge in recognizing HIV symptoms among older persons, (2) older persons and HCPs having low index of suspicion of HIV and (3) poor acceptance of HIV testing among older persons due to perceived personal and social identities. HCPs often missed HIV symptoms and these collectively culminated in OPLWH experiencing complex diagnostic journeys resulting in late HIV diagnosis. To reduce delays in HIV diagnosis, strategies are needed to improve HIV knowledge and risk perception among both older adults and HCPs.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has fueled the widespread adoption of telemedicine in healthcare, particularly in Sarawak, Malaysia. This study investigates the use and acceptance of Sarawak's inaugural multidisciplinary geriatric telemedicine service, TELEG. METHODS: This cross-sectional study took place at the Sarawak Heart Centre's geriatric department from July 1, 2021, to April 30, 2022. Convenient sampling included all TELEG-enrolled patients during this period, to achieve minimum sample size of 148. TELEG's utilization was assessed in terms of medication therapy and treatment plan optimization, as well as enhanced healthcare accessibility. Participants' acceptance of TELEG was measured using the Service User Technology Acceptability Questionnaire (SUTAQ) administered through Google Forms. Descriptive statistics percentages illustrated the proportion of participants who found TELEG moderately to highly acceptable. Associations between baseline characteristics and overall acceptance were explored through bivariate analyses, including Pearson's correlation test, independent t-test, and ANOVA. The influence of six SUTAQ dimensions on overall acceptance, multivariable linear regression using enter method was employed. Statistical significance was determined by p-values less than 0.5. RESULTS: Among 180 geriatric patients enrolled in TELEG during the study period, 149 agreed to participate. TELEG led to medication therapy optimization for 88.6% of participants, primarily involving dose adjustment (44.7%), de-prescribing (31.8%), and prescribing (15.9%). Additionally, 53.8% received treatment plan optimization, predominantly in the form of self-care education (56.3%), referrals for further treatment (33.8%), additional laboratory investigations (29.6%), and increased monitoring (26.8%). Among those educated in self-care (n = 40), dietary intake (27.5%), lower limb exercise (25.0%), and COVID-19 vaccination (12.5%) were the most common topics. All participants expressed moderate to high acceptance of TELEG (mean = 4.9, SD = 0.65, on a scale of 1 to 6). Notably, care personnel concern (B = 0.256; p < 0.001) had the most significant impact on overall acceptance. CONCLUSION: This pioneering study evaluates the utilization and user acceptance of a geriatric telemedicine service in the region, providing valuable insights to support its expansion. Follow-up surveys or interviews to gain insights into users' experiences are crucial to further enhance acceptance.

ABSTRACT

This study evaluated the acceptability and tolerability of three alcohol-based hand rubs (ABHRs) at Sarawak General Hospital, Malaysia. Conducted from 12-26 November 2021 using a modified WHO Protocol, it involved a survey among health workers and concessionaires, with a 35% response rate (1,598 of 4,628 participants). The majority were nurses (60.8%), with the medical division most represented (28.4%). Most respondents (93.2%) used ABHRs at least five days a week and found them easily accessible (72.3%). Product B was the preferred ABHR (65%), primarily for its color and fragrance, surpassing WHO's 50% approval rate in these aspects. However, no other product features met WHO criteria. There were no significant differences in self-reported skin tolerability across the products, and none achieved overall WHO approval. These results offer important insights for ABHR selection in developing countries and highlight the value of the WHO Protocol in assessing product acceptability and tolerability.

ABSTRACT

In Malaysia, despite achieving leprosy-elimination status in 1994, leprosy remains a public health issue among the indigenous Penan community in Sarawak. This study aimed to determine the prevalence trend and clinical profile of leprosy among the Penans in rural Baram, Sarawak, Malaysia. A retrospective records review was conducted on 10-year (2008-2018) time trend of annual prevalence rate and 5-year (2013-2018) Penan leprosy patient clinical profile. Out of the 257 new cases of leprosy reported in Sarawak, 42.8% were Penans, and 72.7% were from Baram. The annual Penan ethnic-specific prevalence rate ranged from 2.08 to 35.5/10 000. Forty-six cases were analyzed for clinical profile: There were more males, active case detection, and multibacillary leprosy. The prevalence trend of leprosy among the Penans in rural Baram exceeded recommended elimination targets. Majority of the cases were detected through active case detection, but cases were detected late. Interventions are needed to improve early diagnosis and detection to achieve elimination of leprosy.

ABSTRACT

INTRODUCTION: Allopurinol, the first-line treatment for chronic gout, is a common causative drug for severe cutaneous adverse reactions (SCAR). HLA-B*58:01 allele was strongly associated with allopurinol-induced SCAR in Asian countries such as Taiwan, Japan, Thailand and Malaysia. HLA-B*58:01 screening before allopurinol initiation is conditionally recommended in the Southeast-Asian population, but the uptake of this screening is slow in primary care settings, including Malaysia. This study aimed to explore the views and experiences of primary care doctors and patients with gout on implementing HLA-B*58:01 testing in Malaysia as part of a more extensive study exploring the feasibility of implementing it routinely. METHODS: This qualitative study used in-depth interviews and focus group discussions to obtain information from patients with gout under follow-up in primary care and doctors who cared for them. Patients and doctors shared their gout management experiences and views on implementing HLA-B*58:01 screening in primary care. Data were coded and analysed using thematic analysis. RESULTS: 18 patients and 18 doctors from three different healthcare settings (university hospital, public health clinics, private general practitioner clinics) participated. The acceptability to HLA-B*58:01 screening was good among the doctors and patients. We discovered inadequate disclosure of severe side effects of allopurinol by doctors due to concerns about medication refusal by patients, which could potentially be improved by introducing HLA-B*58:01 testing. Barriers to implementation included out-of-pocket costs for patients, the cost-effectiveness of this implementation, lack of established alternative treatment pathway besides allopurinol, counselling burden and concern about genetic data security. Our participants preferred targeted screening for high-risk populations instead of universal screening. CONCLUSION: Implementing HLA-B*58:01 testing in primary care is potentially feasible if a cost-effective, targeted screening policy on high-risk groups can be developed. A clear treatment pathway for patients who test positive should be made available.

ABSTRACT

In 2016, a national school-based thalassemia screening programme was implemented in Malaysia. This study aimed to explore the experiences and views of adolescents from an urban school who had undergone the screening programme. We carried out in-depth interviews with 18 participants aged between 18 and 19 years old, with 12 of them identified as carriers during the school screening. Interviews were transcribed verbatim and analysed using thematic analysis. Three main themes emerged from this study: (1) issues encountered at various levels of the school screening programme: appropriate age for screening, thalassaemia education in school, parental consent and follow-up visit and post-test counselling; (2) experiencing emotional rollercoaster: worry, anxiety, shame, stigma; (3) choosing future partners after carrier status was known-prepared or unprepared? Various issues and screening-related challenges were encountered before, during and after the screening test. Recommendations include improving thalassaemia screening education for both school-going adolescents and parents, and better follow-up care and support for those identified as carriers. These will help stakeholders to be well informed and supportive of thalassaemia screening in schools.

ABSTRACT

INTRODUCTION: Outpatient management for dengue fever is the mainstay of treatment for most dengue cases. However, severe dengue can develop rapidly while patients are at home. Understanding the self-care practices and healthcare-seeking behaviours among dengue patients managed as outpatients will help improve the delivery of care to these patients. OBJECTIVE: This study aimed to explore the self-care practices, health-seeking behaviour and outpatient management of dengue fever from the perspectives of patients and primary care physicians. METHODOLOGY: This qualitative study used in-depth interviews and focus group discussions to obtain information from laboratory-confirmed dengue patients who received outpatient care and primary care physicians who cared for them. Patients and physicians shared their experiences and perceptions of self-care practices, decisions to seek urgent care, and outpatient management procedures and visit frequency. Data were coded and analysed using thematic analysis. RESULTS: 13 patients and 11 physicians participated. We discovered that the use of traditional remedies was common with patients perceiving no harm from it, whereas physicians did not see a benefit. Dengue patients' knowledge of warning signs was inadequate despite the information being provided by physicians during clinical follow-up visits. Regarding the decision to seek urgent medical care, physicians assumed patients would seek help immediately once they experienced warning signs. However, for the patients, other factors influenced their health-seeking behaviour, such as their personal perceptions of symptom severity and often more importantly, their social circumstances (e.g., availability of childcare). Patients also described regular outpatient follow-up for dengue as inconvenient. There was variation in the prescribed outpatient follow-up interval recommended by participating physicians who complained about the lack of clear guidelines. CONCLUSION: Perceptions around self-care practices, health-seeking behaviour and outpatient management of dengue often differed between physicians and patients, especially on comprehension of dengue warning signs. Addressing these gaps between patient and physician perceptions and recognition of patient drivers of health-seeking behaviour are needed to improve the safety and delivery of outpatient care for dengue patients.

ABSTRACT

BACKGROUND: In resource-limited settings, HIV-related services are often targeted to younger key populations, although increasing reports have found that adults ≥50 years now account for among the highest increase in new HIV diagnosis. We assessed the proportion of new HIV infections among older adults (≥50 years) and compared their sociodemographics, risk behaviors, and HIV-related outcomes to newly diagnosed younger adults (<50 years). METHODS: This retrospective analysis included all new HIV diagnosis from 2016 to 2019 at the University of Malaya Medical Centre, Malaysia. Trends of HIV diagnosis was assessed using join point regression analysis, and characteristics between the older and younger adults were compared using χ 2 test or Mann-Whitney U test. Kaplan-Meier analysis and log-rank test were used to compare the survival probability in both age groups. RESULTS: From a total of 594 new HIV diagnosis between 2016 and 2019, 11.5% (N = 68) were among older adults with an annual percent increase of 5.50%. Older adults were more likely ethnic Indians ( P < 0.001), acquired HIV through heterosexual contact ( P = 0.001), had late presentation to care ( P = 0.003), and multimorbidity ( P < 0.001). Immunological responses after 12 months on antiretroviral therapy were comparable in both the groups. Older adults had a higher probability of death compared with younger adults (adjusted hazard ratio 1.81, 95% confidence interval: 1.02 to 3.23, P = 0.043) after adjusting for sex, mode of HIV transmission, late presentation to care, antiretroviral therapy initiation, and multimorbidity. CONCLUSION: Older adults diagnosed with HIV were associated with late care presentation and increased mortality. There is an urgent need to enhance uptake of HIV testing and linkage to care among older individuals in our setting.

ABSTRACT

More than 20 years since its discovery, our understanding of Pin1 function in various diseases continues to improve. Pin1 plays a crucial role in pathogenesis and has been implicated in metabolic disorders, cardiovascular diseases, inflammatory diseases, viral infection, cancer and neurodegenerative diseases such as Alzheimer's, Parkinson's and Huntington's disease. In particular, the role of Pin1 in neurodegenerative diseases and cancer has been extensively studied. Our understanding of Pin1 in cancer also led to the development of cancer therapeutic drugs targeting Pin1, with some currently in clinical trial phases. However, identifying a Pin1-specific drug with good cancer therapeutic effect remains elusive, thus leading to the continued efforts in Pin1 research. The importance of Pin1 is highlighted by the presence of Pin1 orthologs across various species: from vertebrates to invertebrates and Kingdom Animalia to Plantae. Among these Pin1 orthologs, their sequence and structural similarity demonstrate the presence of conservation. Moreover, their similar functionality between species further highlights the conservancy of Pin1. As researchers continue to unlock the mysteries of Pin1 in various diseases, using different Pin1 models might shed light on how to better target Pin1 for disease therapeutics. This review aims to highlight the various Pin1 orthologs in numerous species and their divergent functional roles. We will examine their sequence and structural similarities and discuss their functional similarities and uniqueness to demonstrate the interconnectivity of Pin1 orthologs in multiple diseases.

ABSTRACT

BACKGROUND: Effective knowledge transfer of eLearning objects can hasten the adoption and dissemination of technology in teaching and learning. However, challenges exist which hinder inter-organisational knowledge transfer, particularly across continents. The ACoRD project aimed to transfer knowledge on digital learning development from UK/EU (provider) to Malaysian (receiver) higher education institutions (HEIs). This study explores the challenges encountered during the knowledge transfer process and lessons learned. METHODS: This is a qualitative study involving both the knowledge providers and receivers in focus group discussions (n = 25). Four focus group discussions were conducted in the early (n = 2) and mid-phase (n = 2) of the project by trained qualitative researchers using a topic guide designed to explore experiences and activities representing knowledge transfer in multi-institutional and multi-cultural settings. The interviews were audio-recorded, transcribed verbatim, and checked. The transcripts were analysed using thematic analysis. RESULTS: Five main themes emerged from this qualitative study: mismatched expectations between providers and receivers; acquiring new knowledge beyond the professional "comfort zone"; challenges in cascading newly acquired knowledge to colleagues and management; individual and organisational cultural differences; and disruption of knowledge transfer during the COVID-19 pandemic. CONCLUSION: This study highlights the need to create a conducive platform to facilitate continuous, timely and bi-directional needs assessment and feedback; this should be done in the early phase of the knowledge transfer process. The challenges and strategies identified in this study could guide more effective knowledge transfer between organisations and countries.

ABSTRACT

INTRODUCTION: Vaccine safety is a primary concern among vaccine-hesitant individuals. We examined how seven persuasive messages with different frames, all focusing on vaccine safety, influenced Malaysians to accept the COVID-19 vaccine, and recommend it to individuals with different health and age profiles; that is, healthy adults, the elderly, and people with pre-existing health conditions. METHODS: A randomised controlled experiment was conducted from 29 April to 7 June 2021, which coincided with the early phases of the national vaccination programme when vaccine uptake data were largely unavailable. 5784 Malaysians were randomly allocated into 14 experimental arms and exposed to one or two messages that promoted COVID-19 vaccination. Interventional messages were applied alone or in combination and compared against a control message. Outcome measures were assessed as intent to both take the vaccine and recommend it to healthy adults, the elderly, and people with pre-existing health conditions, before and after message exposure. Changes in intent were modelled and we estimated the average marginal effects based on changes in the predicted probability of responding with a positive intent for each of the four outcomes. RESULTS: We found that persuasive communication via several of the experimented messages improved recommendation intentions to people with pre-existing health conditions, with improvements ranging from 4 to 8 percentage points. In contrast, none of the messages neither significantly improved vaccination intentions, nor recommendations to healthy adults and the elderly. Instead, we found evidence suggestive of backfiring among certain outcomes with messages using negative attribute frames, risky choice frames, and priming descriptive norms. CONCLUSION: Message frames that briefly communicate verbatim facts and stimulate rational thinking regarding vaccine safety may be ineffective at positively influencing vaccine-hesitant individuals. Messages intended to promote recommendations of novel health interventions to people with pre-existing health conditions should incorporate safety dimensions. TRIAL REGISTRATION NUMBER: NCT05244356.

ABSTRACT

Shared decision making (SDM) activities in Malaysia began around 2010. The rise in the numbers of patients with chronic disease in Malaysia underscores a growing need for doctors to practice patient-centred care and SDM as more Malaysians come into regular contact with health decision-making scenarios. Recent guidelines for medical professionalism have emphasized that options and risks be discussed in consultations, especially for procedures with risk of adverse outcomes. Although SDM is not legally required, principles of SDM are applied in legal judgements on informed consent. Research on SDM has grown to include the adoption of patient and public involvement in research, an increased emphasis on incorporating local cultural values in SDM, and implementation of SDM in Malaysia's health system and organizational culture. While COVID-19 hindered the progress of SDM research, one positive development was that vaccination choices heightened public consciousness about personal decisional autonomy and the need to discuss pros and cons with doctors before making a medical decision.

ABSTRACT

BACKGROUND: Doctors may struggle to identify patient agendas during busy primary care consultations. Therefore, an online patient agenda tool (the Values in Shared Interactions Tool- VISIT) was developed which allowed patients to enter their agenda items pre-consultation for doctors to view on their electronic medical records (EMR). This study aimed to measure the impact of this EMR-integrated website on patient satisfaction, number of agenda items discussed and consultation time. METHODS: An unblinded cluster-randomized controlled trial was conducted in a university-based primary care clinic between June-October 2019. Twenty-five family medicine trainees were randomized into using the VISIT tool (intervention) and usual care (control). Descriptive analysis showed significant differences between arms for age, occupation and mobile device proficiency scores. These were entered as covariates in trial analyses. Primary outcome was mean self-reported patient satisfaction score using the Healthcare Provider-Patient Communication (HCPPC) questionnaire, secondary outcomes were mean agenda items per consultation and mean consultation time. RESULTS: The intervention arm had 12 doctors and 109 patients; the control arm had 13 doctors and 137 patients. Participation rates were 25.5% for intervention vs 53.6% for control. There was no difference between arms for patient satisfaction scores (133.3, 95% CI: 130.67-135.88 intervention vs 134.0, 95% CI: 131.76-136.29 control, P =.680) and consultation duration (15.83 min, 95% CI: 13.66-17.99 intervention vs 15.45 min, 95% CI: 13.57-17.34 control, P =.805). Mean number of agenda items discussed was higher in the intervention arm (2.25 items, 95% CI: 2.06-2.44 intervention vs 1.94 items, CI 95%: 1.78-2.11, P =.024). CONCLUSIONS: Integrating patient agendas into the EMR did not affect patient satisfaction compared to usual care but was associated with a slightly increased number of agenda items without an increase in consultation time. This shows it may be useful for a busy primary care setting with multiple comorbidities and short consultation times.

ABSTRACT

BACKGROUND: This study explored the user experiences of paediatric postgraduate trainees in Malaysia and Thailand in using a 2 h and 15 min online module for breastfeeding developed for Southeast Asia, which was adapted from existing European online modules for European and German Continuing Medical Education (CME) credits. METHODS: A qualitative study using focus group discussions (FGDs) was conducted with paediatric postgraduate trainees who used an online English-language breastfeeding module in two Thai universities (May 2020, done online) and two Malaysian universities (Sept- Nov 2019, in-person). FGDs explored module usability and utility. Sessions were transcribed verbatim and analysed thematically. The process of coding was done collaboratively by Thai and Malaysian researchers. RESULTS: Twenty Six resident trainees participated (Thai, n = 13; Malaysian, n = 13). Ages ranged from 29-34 years old, with 21 females. Nineteen participants had never used online learning modules prior to this. Participants took between 1 to 5 sessions to complete the breastfeeding module. Four themes emerged from their experience. 1) The online learning module was more engaging and detailed than previous lectures, courses and/or books, but lacked hands-on training. 2) Using an online platform facilitated learning as eased navigation and resource searching, however, problems were encountered navigating the module on some devices. 3) Learners preferred less words and more graphics, as this helped them capture key messages. 4) Regionally tailored content elicited a mixed reaction from participants. CONCLUSIONS: Users found that the adapted module compared favourably with previous learning experiences. However, online learning modules lack hands-on training, and implementation should ideally incorporate a mix of both. Consideration of device diversity and preferences for how content was adapted for local settings are needed for tailoring.

ABSTRACT

As a potential clinical therapeutic cell for injured tissue repair, mesenchymal stem cells (MSCs) have attracted increasing attention. Enhancing the pro-healing function of MSCs has gradually become an essential topic in improving the clinical efficacy of MSCs. Recently, studies have shown that neuronal protein 3.1 (P311) plays a crucial role in promoting skin wound healing, suggesting P311 gene modification may improve the pro-healing function of MSCs. In this study, we demonstrated that increasing the in vivo expression of P311 could significantly enhance the ability of MSCs to lessen the number of inflammatory cells, increase the expression of IL10, reduce the levels of TNF-α and IFN-γ, increase collagen deposition, promote angiogenesis, and ultimately accelerate skin wound closure and improve the quality of wound healing. Importantly, we uncovered that P311 enhanced the pro-angiogenesis function of MSCs by increasing the production of vascular endothelial growth factor (VEGF) in vitro and in vivo. Mechanistically, we revealed that the mTOR signalling pathway was closely related to the regulation of P311 on VEGF production in MSCs. Together, our data displayed that P311 gene modification in MSCs augments their capabilities to promote skin wound closure, which might bring the dawn for its clinical application in the future.

ABSTRACT

BACKGROUND: The uptake of risk-reducing salpingo-oophorectomy (RRSO) in Asian countries is variable despite being the most effective option for ovarian cancer risk reduction in BRCA mutation carriers. Exploration of factors which may impact the RRSO decision-making of BRCA mutation carriers from Malaysia, a developing country in Southeast Asia, was undertaken. METHODS: In-depth interviews with 28 Malaysian BRCA mutation carriers with a history of breast cancer were conducted in addition to observing their RRSO decision-making consultations in the clinic. RESULTS: The decision-making considerations among the carriers were centered around the overarching theme of "Negotiating cancer risk and womanhood priorities," with the following themes: (1) risk perception, (2) self-preservation, (3) motherhood obligation, and (4) the preciousness of marriage. Cognitive knowledge of BRCA risk was often conceptualized based on personal and family history of cancer, personal beliefs, and faith. Many women reported fears that RRSO would affect them physically and emotionally, worrying about the post-surgical impact on their motherhood responsibilities. Nevertheless, some reported feeling obliged to choose RRSO for the sake of their children. For some, their husband's support and approval were critical, with emotional well-being and sexuality reportedly perceived as important to sustaining married life. Despite reporting hesitancy toward RRSO, women's decisions about choosing this option evolved as their priorities changed at different stages of life. CONCLUSIONS: Recognizing during clinic encounters with Malaysian women that RRSO decision-making involves negotiating the likelihood of developing cancer with the societal priorities of being a woman, mother, and wife may serve to support their decision-making.

ABSTRACT

The decision to have risk-reducing salpingo-oophorectomy (RRSO) by BRCA mutation carriers to reduce the risk of ovarian cancer is difficult. The choice involves trade-offs in terms of its risks and benefits. To date, understanding the decision-making needs of RRSO among Southeast Asian BRCA mutation carriers is limited. This study aimed to explore the decision-making needs of Malaysian BRCA mutation carriers as an exemplar for the Southeast Asian community. In-depth interviews and clinic observations were conducted with 31 BRCA mutation carriers and analysed thematically. The core theme identified was 'Coping with complex information and alleviating uncertainties' with the following subthemes: (1) the need for an adjustment period, (2) information support, (3) social support and, (4) religious support. We found that women required time to accept their BRCA mutation status before they were ready to make a risk-reducing choice; that understanding complex genetic information and multiple risk management options can be an overwhelming experience; and obtaining further information and a second opinion were challenging. Many described the need for experiential information from other peer-carriers who had undergone RRSO. Support from their spouse and family members was thought to be essential for them to feel reassured with their decision. Many relied on religion to positively cope with cancer risk and cancer worry; Muslim BRCA carriers sought religious guidance through prayers and Islamic fatwas to feel more certain about their RRSO decision. These findings underscore the importance of the provision of resources and support that includes input from peers, husband, family members and religion to underpin the decision-making needs of Malaysian BRCA mutation carriers considering RRSO.

ABSTRACT

INTRODUCTION: A compulsory research component is becoming increasingly common for clinical residents. However, integrating research into a busy clinical training schedule can be challenging. This study aimed to explore barriers to research supervision in specialist training programmes from the perspectives of clinical supervisors and trainees at a Malaysian university hospital. METHODS: Qualitative interviews and focus group discussions were conducted (December 2016 to July 2017) with clinical supervisors (n=11) and clinical trainees (n=26) utilising a topic guide exploring institutional guidelines, research culture and supervisor-student roles. Interviews were transcribed verbatim and analysed thematically to identify barriers to research supervision. RESULTS: Supervisors and trainees from 11 out of 18 departments participated. Both clinical supervisors and trainees struggled to successfully integrate a compulsory research component into residency training. Among the reasons identified included a lack of supervisory access due to the nature of clinical rotations and placements, clashing training priorities (clinical vs research) that discouraged trainees and supervisors from engaging in research, poor research expertise and experience among clinical supervisors hampering high-quality supervision, and a frustrating lack of clear standards between the various parties involved in research guidance and examination. CONCLUSION: Both clinical supervisors and trainees struggled to successfully integrate a compulsory research component into residency training. This was not only an issue of resource limitation since questions regarding clinical priorities and unclear research standards emerged. Thus, institutional coordinators need to set clear standards and provide adequate training to make research meaningful and achievable for busy clinical supervisors and trainees.
