    ABSTRACTS FOR INTERNATIONAL HEALTH AND MEDICAL SCIENCES CONFERENCE 2019 (IHMSC 2019)
    Held at Taylor’s University Lakeside Campus, Subang Jaya, Selangor, Malaysia, 8-9th March, 2019
    Introduction: Unsafe blood products cause transfusion-transmissible infections among blood receivers. The knowledge and perception of blood donors is important as it is associated with their donation behaviour and hence the safety of blood products. There was no previous study that assessed the knowledge and perception on blood safety issues among blood donors to date. The objective of this study was to assess the knowledge and perception of blood
    donors on blood safety issues.
    Methods: This was a pilot study conducted to pilot test the self-developed questionnaire by the researchers. The questionnaire was available in the Malay language. One-hundred-thirty donors at the National Blood Centre were recruited to complete the self-administered questionnaire. Health sciences professionals, medical students and non-Malaysians were excluded in this study.
    Results: A total of 130 donors comprising of 70 males (53.8%) and 60 females (46.2%) responded. The mean age of the respondents is 32.48±8.86 years. Most of the respondents were Malay (55.4%), single (49.2%), working in private sector (46.9%) and regular donor (68.5%). More than half of the respondents did not know that dengue, Zika and mad-cow disease can be contracted through blood transfusion. Ten percent of the respondents answered that bisexual people are eligible to donate blood. 40.7% of the donors agreed to check their HIV status through blood donation. Majority of the donors (60.7%) agreed that the donors’ blood is safe if the screening test is negative. Whereas, 33.9% of the donors disagreed that they shall be responsible if their blood causes infection.
    Conclusion: Several knowledge gaps and inappropriate perception among the respondents were identified and these might affect the safety of the blood products. Targeted measures should be taken to rectify donors’ knowledge and perception in order to minimise inappropriate blood donor behaviours and reduce unsafe blood products.

    OBJECTIVES: To explore the perceived motivators, training supports and challenges to career advancement among fully and provisionally registered pharmacists (FRPs and PRPs) in the Malaysian public service.

    METHODS: Nine hundred and fifty-three pharmacists in the public service of Perak State, Malaysia, were invited for participation in an online survey that was conducted in October 2018. Based on a 5-point Likert scale, they were required to respond to 56 items, ranging from the perceived availability and importance of both motivators and training supports, the challenges to career advancement, to the awareness of the need for career planning. Their responses were subsequently dichotomized into 'agree'/'important' and 'disagree'/'not important'.

    KEY FINDINGS: Four hundred and eighty pharmacists participated in the survey, yielding a response rate of 51.2%. More than half of them agreed with the inflexibility of working time and the absence of a performance-based salary and promotion scheme. More than 80% of them also highly valued the training in both pharmacy-related areas and management. Apart from inadequate training, no specialization in pharmacy as a profession and the absence of a performance-based promotion scheme were identified as the major challenges to their career advancement. As compared with the PRPs, the FRPs had greater concern over the absence of a performance-based salary and promotion scheme, flexible working time and periodic feedback for their work performance.

    CONCLUSIONS: The findings indicate the inadequacy of the current system in providing recognition, training, feedback for work performance and a clear career pathway to pharmacists in the Malaysian public service, which warrants a change.

    INTRODUCTION: This study was designed to determine the influence of bariatric surgery on changes in the body mass index (BMI), and the control of diabetes, hypertension and dyslipidaemia among obese patients in Malaysia.

    MATERIALS AND METHODS: This was a retrospective cohort study undertaken at a public tertiary care centre in the state of Perak, Malaysia. Information of obese patients who underwent bariatric surgery was obtained from their medical records. The changes in the BMI, HbA1C, systolic and diastolic blood pressure (SBP and DBP), and lipid levels between three months before and after the surgery were assessed.

    RESULTS: The patients (n=106) were mostly Malay (66.0%), had at least one comorbidity (61.3%), and had a mean age of 40.38±11.75 years. Following surgery, the BMI of the patients was found to reduce by 9.78±5.82kg/m2. For the patients who had diabetes (n=24) and hypertension (n=47), their mean HbA1C, SBP and DBP were also shown to reduce significantly by 2.02±2.13%, 17.19±16.97mmHg, and 11.45±12.63mmHg, respectively. Meanwhile, the mean total cholesterol, triglyceride and low-density lipoprotein levels of those who had dyslipidaemia (n=21) were, respectively, lowered by 0.91±1.18mmol/L, 0.69±1.11mmol/L and 0.47±0.52mmol/L.

    CONCLUSION: The findings suggest that in addition to weight reduction, bariatric surgery is helpful in improving the diabetes, hypertension and dyslipidaemia control among obese patients. However, a large-scale trial with a control group is required to verify our findings.

    Introduction: The present study aimed to determine the prevalence of hypertension and its association with nutritional status (body mass index, body fat percentage, and visceral fat) among students in a public university in Sarawak, Malaysia.

    Methods: This was a cross-sectional study among undergraduate students aged 18 years old and above. Anthropometric measurements, such as weight, height, body composition, and blood pressure measurements, were collected. Hypertension was defined as equal or more than 140/90 mmHg. Statistical analyses were done using IBM SPSS version 20.

    Results: A total of 354 respondents participated in the study. Mean age for the respondents was 21 years (SD 1.18 years). About 40% of the respondents were overweight or obese. Prevalence of hypertension was 8.2%. Mean systolic blood pressure was 119.1mmHg (SD14.36mmHg), and the mean diastolic blood pressure was 72.6mmHg (SD 9.73mmHg). There is a significant association between male gender (odds ratio =3.519, 95% CI is 1.886-6.566), body fat percentage (odds ratio = 1.944, 95% CI is 1.050-3.601), visceral fat (odds ratio = 2.830, 95% CI is 1.346-5.951), and family history of hypertension (odds ratio= 2.366, 95% CI is 1.334-4.194) and hypertension.

    Conclusion: The prevalence of hypertension was less than 10% and is associated with male gender, body composition, and family history of hypertension.

    INTRODUCTION: There is an increase in the prevalence of overweight and obesity in Malaysia. Besides prevalence studies, not much is known about either overweight or obese individuals. The objective of this study was to determine the stages of change in losing weight and the self-efficacy in eating control of three indigenous groups of overweight and obese adults in Sarawak, Malaysia.
    METHODS: A cross-sectional study was conducted in one rural region in Sarawak using a purposive sample. A structured questionnaire, which included two scales: (1) Weight: Stages of change (SOC) to assess readiness to change; and (2) Weight Efficacy Lifestyle Questionnaire (WEL) (both adopted from the transtheoretical model of change); and a set of pre-tested questionnaires on socio-demographic data, the presence of health problems and self-assessment of weight appropriateness, was used to interview respondents.
    RESULTS: The stage distribution for weight loss of these adults respondents (n = 271) showed that 60.5% (n = 164) were in the pre-contemplation stage, 20.7% (n = 56) were in the contemplation stage, 8.5% (n = 23) were in the preparation stage, and 8.9% (n = 24) were in the action stage, while only 1.5% (n = 4) were in the maintenance stage. Except for education, the stage differences were generally stable across age, sex, race, household income, presence or absence of health problem, self-perceived weight and presence of overweight or obesity. Respondents were least able to control their eating under social pressure and food availability, according to their WEL score.
    CONCLUSION: A large proportion of the overweight or obese adults was not intending to lose weight. The factor structure of the two WEL original subscales enabled partial differentiation between respondents who were able or unable to resist eating in situations where there were availability of food and experienced physical discomfort. The study results indicate the importance of assessing individuals' SOC score in order to implement stage-matched intervention strategies. More studies should be performed in order to validate the WEL questionnaire for use with a Malaysian sample.

    The objective of this study was to explore the perception of, feelings and attitudes toward overweight or obesity, and the perceived barriers to weight loss among native adults from lower socio-economic background. A total of six gender- and ethnic-specific focus groups consisted of 38 overweight and obese purposefully and criterion selected adults (21 women and 17 men), participated in this study. An unstructured discussion guide based on the study objectives were used for the focus groups. The results showed that some participants perceived themselves as ugly, felt ashamed of their body size and were frustrated because they did not desire to be overweight. Due to their excess weight, most also expressed they were less effective in their work performances. Although some participants had negative attitudes toward themselves because of excess weight, this appeared to link to self-stigmatization rather than anti-obesity discrimination. The participants remained in the Pre-contemplation stage of losing weight probably because of perceived barriers such as difficulty to resist eating, lack of know how and previous failed attempts to lose weight. Importantly, this study provided some evidence that individuals in the Pre-contemplation stage are unable to take action to lose weight, even if effective strategies are suggested.

    Diabetes mellitus is a public health concern in Malaysia. Treatment of diabetes is costly and can lead to complications if disease is poorly controlled. Diabetes self-management (DSM) is found to be essential for optimal glycemic control. This cross-sectional study was conducted among samples from four randomly selected diabetes clinics in Sarawak, Malaysia. The aim was to determine the predictors for DSM. Face-to-face interview using questionnaire was used to collect data. Four hundred respondents with type 2 diabetes mellitus (T2DM) were recruited. Majority of the respondents were Sarawak Bumiputra (Iban and Bidayuh, 48.6%) and female (68.6%). The mean age was 58.77 years (SD = 11.46) and approximately half of the respondents (50.6%) had T2DM for six years (SD = 4.46). The mean fasting blood glucose (FBG) was 8.06 mmol/L (SD = 2.94), with majority (76.1%) having the level higher than 6.1 mmol/L. Multiple logistic regression tests showed significant linear relationship between DSM and belief in treatment effectiveness (p = 0.001), family support (p = 0.007), and self-efficacy (p = 0.027). Health care personnel must convince patients with T2DM of the effectiveness of the treatment, empower and enhance their self-efficacy, and enlist the family support so as to ensure patients sustain their DSM efforts.

    Background: Coronary heart disease (CHD) was the second leading cause of death in Malaysia in 2006. CHD has known risk factors including hypertension, diabetes mellitus, and obesity.
    Methods: This cross-sectional study examined the prevalence of cardiovascular risk factors among 260 participants aged 20 to 65 years in a rural community in Sarawak.
    Results: The prevalences of overweight and obesity in this study were 39.6% and 11.9%, respectively. Approximately 13% of participants had hypertension, and 1.5% had a random blood sugar greater than 11.1 mmol/L. Chi-square tests showed significant associations between obesity and gender (P = 0.007), low high-density lipoprotein cholesterol and race (P = 0.05), high total cholesterol and age (P = 0.007), age and hypertension (P = 0.011), smoking and gender (P < 0.001), and smoking and income (P = 0.050). Age-adjusted logistic regression showed that women were 0.246 times more likely to be obese, that older participants (> 45 years) were 0.395 times more likely to have high cholesterol and that those with a higher monthly household income (> RM830) were 2.471 times more likely to smoke.
    Conclusion: These findings indicate that we should be concerned about the high rates of overweight in this rural community to prevent obesity.

    Allergic rhinitis has been identified as a major respiratory disease that places a significant burden on patients and the healthcare system. Nevertheless, the management of allergic rhinitis is challenging for both patients and practitioners. Pharmacists have been recognised as strategic in providing advice for allergic avoidance, disease information, and pharmacological care for allergic rhinitis management. This role has been underutilised in the public health service sector in Malaysia due to variation in practice, regulation, and health system structures when compared to the international guidelines. This article proposed a PhaRmacISt-led Education Model (AR-PRISE) that includes explicit patient education materials and an algorithm for structured counselling by pharmacists in the management of patients with allergic rhinitis.

    BACKGROUND: Patient's awareness and satisfaction towards ward pharmacy services may influence perception towards effectiveness and safety of drugs, affecting medication adherence and clinical outcome. Nevertheless, studies on local ward pharmacy services were lacking. This study evaluated awareness, expectation and satisfaction of ward pharmacy services among patients in medical wards and determined their association with demographic characteristics.

    METHODS: This was a cross-sectional study using self-administered questionnaire conducted in medical wards of fourteen Perak state public hospitals from September to October 2020. In-patients aged ≥18 years old were included. The validated questionnaire had four domains. The student's t-test, one-way analysis of variance (ANOVA) and multiple linear regression were was employed to evaluate the association between patients' demographic characteristics with their awareness, expectation and satisfaction towards ward pharmacy services.

    RESULTS: 467 patients agreed to participate (response rate = 83.8%) but only 441 were analysed. The mean age of the patients was 54.9 years. Majority was male (56.2%), Malay (77.3%), with secondary education (62.9%), rural resident (57.1%) and reported good medication adherence (61.6%). The mean awareness score was 49.6 out of 60. Patients were least aware about drug-drug interaction (3.85 ± 1.15) and proper storage of medications (3.98 ± 1.06). Elderly patients (β = - 2.82, P

    Drug-related problems (DRPs) in the elderly include polypharmacy, potentially inappropriate medications, nonadherence, and drug-related falls. In this systematic review and meta-analysis, the prevalence of DRPs and complementary and alternative medicine (CAM) use among the Malaysian elderly was estimated. PubMed, Scopus, Web of Science, and Google Scholar databases were searched to identify studies published since their inception up to 24 August 2020. A random-effects model was used to generate the pooled prevalence of DRPs along with its corresponding 95% confidence interval (CI). The heterogeneity of the results was estimated using the I2 statistics, and Cochran's Q test and sensitivity analyses were performed to confirm the robustness of the results. We identified 526 studies, 23 of which were included in the meta-analysis. (n = 29,342). The pooled prevalence of DRPs among Malaysian elderly was as follows: (1) polypharmacy: 49.5% [95% CI: 20.5-78.6], (2) potentially inappropriate medications: 28.9% [95% CI: 25.4-32.3], (3) nonadherence to medications: 60.6% [95% CI: 50.2-70.9], and (4) medication-related falls 39.3% [95% CI: 0.0-80.8]. Approximately one in two Malaysian elderly used CAM. The prevalence of polypharmacy and potentially inappropriate medications among the Malaysian elderly population was high, calling for measures and evidence-based guidelines to ensure the safe medication use.

    BACKGROUND: Caregivers' knowledge, practice and adherence in medication administration who care for children with chronic illness requiring long-term pharmacological treatments are factors associating with children medication safety at home. This study aimed to determine the medication-related knowledge, administration practice and adherence among caregivers of chronically ill children in Malaysia. This cross-sectional study was conducted at the paediatric outpatient clinic of a tertiary public hospital. Caregivers of chronically ill children, who engaged in medication administration at home for at least 3 months, were conveniently recruited. Their medication-related knowledge and administration practice were evaluated based on a checklist, while their adherence to medication administration was assessed using a validated 5-point scale. The associated factors were also explored.

    RESULTS: Of the 141 participants, most were mothers (90.8%) and had a full-time job (55.3%). Most of them had adequate medication-related knowledge (71.6%) and an appropriate administration practice (83.0%). The majority of them (83.0%) also rated themselves as adherent to medication administration. The participants with a child above 5 years of age (91.2%) were found to have a better practice than those with younger children (75.3%) in medication administration (p = 0.012). However, those with a child taking two (adjusted OR: 12.53) or three (adjusted OR: 8.29) medications, getting their refills from private health institutions apart from this hospital (adjusted OR = 7.06) and having multiple illnesses (adjusted OR = 21.25) were more likely to be not adherent to medication administration.

    CONCLUSION: Caregivers of chronically ill children in Malaysia generally have sufficient knowledge and an appropriate practice of medication administration at home. Yet, strategies to improve the adherence to medication administration, particularly in those who care for children with complicated health conditions, are warranted.

    Protecting healthcare workers (HCWs) who are in the frontline during the time of the COVID-19 pandemic is paramount. The filtering facepiece respirators (FFRs) or N95 respirator is one of the personal protective equipment (PPE) used to protect HCWs exposed to airborne pathogens in clinical practice or when performing aerosol generating procedures. The FFRs should be able to serve the intended purpose without causing additional health and safety hazards for the HCWs. The following commentary will provide some basic information on selecting correct FFRs and conducting fitness test.

    AIM: Bed sharing is defined as a newborn sleeping in the same bed with an adult. Bed sharing may put the newborn at risk of suffocation due to accidental smothering.

    METHODS: This was a quasi-experimental study conducted in a tertiary referral hospital. Healthy post-delivery Malaysian mothers were randomly selected and enrolled into the control or the intervention group. On the day of discharge, mothers in the intervention group were interviewed face-to-face in the post-natal ward on their plans for sleeping arrangement with their newborn. After the interview, mothers were advised not to bed share with their newborn and were given an educational leaflet on safe sleeping practices. One week after discharge, mothers in both groups were interviewed over the telephone regarding their actual sleeping arrangements with their newborn using the same questionnaire. Logistic regression was performed to determine factors associated with reduced bed sharing.

    RESULTS: A total of 94 mothers and 95 mothers were recruited to the control and intervention group, respectively. The baseline bed-sharing prevalence was similar between groups: 60.6% in the control group and 61.1% in the interventional group. The proportion of mothers who bed shared with their newborn reduced from 61.1 to 37.9% after the intervention (P changed their sleeping practices after receiving the intervention in the form of an information leaflet.

    This cross-sectional study was conducted to determine the predictive power of anthropometric indicators and recommend cutoff points to discriminate hypertension among adolescents in Sarawak, Malaysia. A total of 2461 respondents aged 12-17 years participated in this study with mean age of 14.5±1.50 years. All anthropometric indicators had significant area under the ROC curve, with body mass index (BMI) and waist circumference (WC) ranging from 0.7 to 0.8. The best anthropometric indicators for predicting hypertension for boys were WC, BMI, and waist-to-height ratio (WHtR). For girls, BMI was the best indicators followed by WHtR and WC. The recommended BMI cutoff point for boys was 20 kg/m2 and 20.7 kg/m2 for girls. For WC, the recommended cutoff point was 67.1 cm for boys and 68.2 cm for girls. BMI and WC indicators were recommended to be used at the school setting where the measurement can easily be conducted.

    This commentary shares the experience of a hospital pharmacy department in providing healthcare services during the COVID-19 outbreak in Malaysia. During this pandemic, the medication delivery system is redesigned to minimize contact among patients and the health care providers. Also, the remote medication monitoring system was implemented to deliver pharmaceutical care for inpatients. Communication technology was used to assist the pharmacist in medication counseling. QR codes to access videos demonstrating the use of devices were made available for patients. Pharmacists were also tasked with the procurement of personal protective equipment and medications needed requiring special approval from the Ministry of Health.
