    Introduction: Previous studies reported that a two-week double-dose clopidogrel treatment following percutaneous coronary intervention has no difference in safety compared to standard therapy. This study aimed to determine the all-cause readmission rate and survival after a year of percutaneous coronary intervention (PCI) in patients who were treated with two-week double-dose clopidogrel regimen. Methods: This was a retrospective study on patients who underwent PCI in a state general hospital in Malaysia in 2014. Patients’ one month and one-year survival status were retrieved using the hospital electronic patient management system. Patients who received a two-week course of 150mg clopidogrel and subsequently a one-year course of standard double antiplatelet therapy were included. Results: A total of 381 out of 563 patients who underwent PCI were included in the analysis, while those who were switched to ticagrelor and transferred to other hospitals post-PCI excluded. Patients had a mean age of 56.9 (SD 10.7), with majority male (331, 86.9%) and Malay (144, 37.8%). The PCI was mainly indicated for ST-elevated myocardial infarction (188, 49.3%), non-STEMI (114, 29.9%) and unstable angina (36, 9.4%). A total of 107 (28.1%) patients were readmitted within the one year post-PCI period. Readmissions were mainly due to ACS (55.5%) and bleeding events (2.4%). The 30-day and 1-year all-cause mortality was 33 cases and 43 cases, respectively. Conclu- sion: The low readmission and bleeding related readmission suggested that the two-week double-dose clopidogrel regimen was safe for the post PCI patients. Future randomised trial to establish the efficacy of this dosing regimen is therefore 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.

    BACKGROUND: Explicit potentially inappropriate medications (PIM) criteria are commonly used to identify and deprescribe potentially inappropriate prescriptions among older patients. Most of these criteria were developed specifically for the Western population, which might not be applicable in an Asian setting. The current study summarizes the methods and drug lists to identify PIM in older Asian people.

    METHODS: A systematic review of published and unpublished studies were carried out. Included studies described the development of explicit criteria for PIM use in older adults and provided a list of medications that should be considered inappropriate. PubMed, Medline, EMBASE, Cochrane CENTRAL, CINAHL, PsycINFO, and Scopus searches were conducted. The PIMs were analyzed according to the general conditions, disease-specific conditions, and drug-drug interaction classes. The qualities of the included studies were assessed using a nine-point evaluation tool. The kappa agreement index was used to evaluate the level of agreement between the identified explicit PIM tools.

    RESULTS: The search yielded 1206 articles, and 15 studies were included in our analysis. Thirteen criteria were identified in East Asia and two in South Asia. Twelve out of the 15 criteria were developed using the Delphi method. We identified 283 PIMs independent of medical conditions and 465 disease-specific PIMs. Antipsychotics were included in most of the criteria (14/15), followed by tricyclic antidepressants (TCAs) (13/15), antihistamines (13/15), sulfonylureas (12/15), benzodiazepines (11/15), and nonsteroidal anti-inflammatory drug (NSAIDs) (11/15). Only one study fulfilled all the quality components. There was a low kappa agreement (k = 0.230) between the included studies.

    CONCLUSION: This review included 15 explicit PIM criteria, which most listed antipsychotics, antidepressants, and antihistamines as potentially inappropriate. Healthcare professionals should exercise more caution when dealing with these medications among older patients. These results may help healthcare professionals in Asian nations to create regional standards for the discontinuation of potentially harmful drugs for elderly patients.

    Objective: To develop and validate a questionnaire which evaluates the blood donors' satisfaction.

    Background: In Malaysia, blood procurement relies mainly on voluntary non-remunerated donors. Hence, it is important to ensure the satisfaction of the blood donors in order to increase retention.

    Methods: This study was conducted among blood donors who attended blood donation and understood the Malay language. Non-Malaysian and illiterate donors were excluded. The questionnaire was developed by the transfusion medicine team. Content validity was established by content reviewers, while face validity was examined in the cognitive debriefing stage. For the 18-item questionnaire, 90 respondents were required based on the 1:5 ratio. A retest was performed in two weeks' time.

    Results: One hundred and thirty-seven participants responded in the first phase, while 103 responded after two weeks. The five domains were: technical, interpersonal, accessibility/ convenience, physical experience and overall satisfaction. The Kaiser-Meyer-Olkin (KMO) value was 0.896, with significant Bartlett's Test of Sphericity (P < 0.001). The factor loadings ranged from 0.729 to 0.953. The Cronbach alpha values of the five domains ranged from 0.814 to 0.955 and the intraclass correlation coefficient ranged from 0.663 to 0.847.

    Conclusion: The Malaysian blood donor's satisfaction (M-BDS) questionnaire is a reliable and valid tool suitable for the assessment of blood donor's satisfaction in blood donation centres.

    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.

    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.

    The coronavirus disease 2019 (COVID-19) cases was on an increasing trend, including in Malaysia. The Malaysian Ministry of Health had implemented a range of measures, such as the use of masks and social distancing, to reduce the risk of transmission. Traditionally, newborns are evaluated for neonatal jaundice using visual assessment, a capillary heel prick and serum bilirubin (SB) sampling in primary health-care clinics. This approach requires the physical presence of both parents and their newborns in the primary health-care clinics, causing crowding and increasing the risk of COVID-19 infections. To alleviate crowding, we implemented the transcutaneous bilirubin drive-through (DT) service, which is an established, non-invasive, painless and rapid method to determine the bilirubin levels. Throughout the screening, both parents and baby will be confined to their car. A total of 1842 babies were screened in our DT setting from April to July 2020. Of the total babies, 298 (16.1%) required venesection for SB measurement and 85 required admission for phototherapy. None with severe jaundice were missed since the implementation of this service. The average test duration per neonate was less than 5 min, while conventional venous bilirubin laboratory testing required an average of 1.5 h per neonate. The cost of the SB laboratory test and consumables was approximately USD 5 per test, with an estimated cost savings of USD 7720. DT screening may be introduced in health-care settings to reduce crowding and eliminate the need of painful blood sampling in newborns.

    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.

    BACKGROUND: Social stigma against persons infected with COVID-19 is not uncommon. This qualitative study aimed to explore the experience of social stigma among COVID-19 positive patients and their family members.

    METHOD: This cross-sectional study was conducted between April to June 2020 in Malaysia. Patients who have recovered from COVID-19 for at least 1 month and their family members who were tested with negative results, Malaysian and aged 18-65 years old were purposively sampled. Cold call method was employed to recruit patients while their family members were recruited by their recommendations. Telephone interviews were conducted with the participants after obtaining their verbal consent.

    RESULTS: A total of 18 participants took part in this study. Three themes emerged from the interviews: (Ι) experience of stigmatization, (ΙΙ) perspective on disease disclosure, and (ΙΙΙ) suggestion on coping and reducing stigma. The participants expressed their experiences of being isolated, labelled, and blamed by the people surrounding them including the health care providers, neighbours, and staff at the service counters. Some respondents expressed their willingness to share their experience with others by emphasizing the importance of taking preventive measure in order to stop the chain of virus transmission and some of them chose to disclose this medical history for official purpose because of fear and lack of understanding among the public. As suggested by the respondents, the approaches in addressing social stigma require the involvement of the government, the public, health care provider, and religious leader.

    CONCLUSION: Individuals recovered from COVID-19 and their families experienced social stigma. Fear and lack of public understanding of the COVID-19 disease were the key factors for non-disclosure. Some expressed their willingness to share their experience as they perceived it as method to increase public awareness and thereby reducing social stigma. Multifaceted approaches with the involvement of multiple parties including the government, non-governmental organization as well as the general public were recommended as important measures to address the issues of social stigma.

    BACKGROUND: Antibiotic resistance is a major public health concern, accelerated by antibiotic overuse. Inadequate knowledge among the public has been associated with inappropriate use of antibiotics. This study determined the impact of a self-developed educational leaflet for addressing specific knowledge gaps in antibiotic use among the public.

    METHODS: This was an experimental study conducted at five hospitals and 20 primary health care clinics in the state of Perak. Adults over 18 years of age were recruited using sequential sampling. The first phase of data collection consisted of a pre-intervention assessment, an educational session, and an immediate post-intervention assessment. Each educational session was conducted by trained pharmacists and lasted approximately 15 min for each participant. A two-week post-intervention assessment was then conducted via a phone call to re-assess the participants using the same questionnaire.

    RESULTS: Out of 300 questionnaires distributed, 234 were completed for our study. The mean age of participants was 40.7 ± 14.6 years old. Most of the respondents were female (143, 61.1%), Malay (162, 69.2%), and had tertiary education (162, 69.2%). A mean score was generated for each domain, with knowledge towards antibiotic resistance: 2.83 ± 1.28 pre-intervention, 3.76 ± 0.62 immediate post-intervention, and 3.67 ± 0.78 two-weeks post-intervention (total score: 4.00); knowledge towards antibiotic use: 2.03 ± 1.56 pre-intervention, 4.56 ± 1.46 immediate post-intervention, and 4.32 ± 1.48 two-weeks post-intervention (total score: 6.00); perception towards antibiotic use: 2.83 ± 1.38 pre-intervention, 4.25 ± 1.06 immediate post-intervention, and 4.22 ± 1.02 two-weeks post-intervention (total score: 5.00). Significant improvement in the mean scores were found before and after intervention in all domains (p

    This exploratory qualitative study investigates older adults' unmet needs in the age-friendly city of Ipoh, Malaysia. Seventeen participants were interviewed, including ten older adults residing in Ipoh City for at least six months, four carers, and three professional key informants. Interviews were conducted using semi-structured questions based on the WHO Age-Friendly Cities Framework. A 5P framework for active ageing based on the ecological ageing model was adapted for data analysis. The 5P framework consists of domains of person (micro), process (meso), place (macro), policymaking (macro), and prime, which allows for the dissection of older adults' unmet needs in planning for multilevel approaches, which were employed for analysis. Person: the personal needs requiring improvement included digital divide disparity, inadequate family support, and restricted sports activities attributed to physical limitations. Process: There were fewer social activities and a lack of low-cost and easily accessible venues for seniors. Economic challenges include expensive private healthcare services, variation in the quality of care in older residential care facilities, and limited savings for retirement. Place issues include unequal distribution of exercise equipment, public open spaces, the need for more conducive parking for seniors, and a place for social activities. Difficulties assessing public transportation, digitalized services, and unaffordable e-hailing services are common among seniors. Housing issues for seniors include a lack of barrier-free housing design and unaffordable housing. Policymaking: Insufficient private sector commitment to improving services to older adults, lack of policy governance on the quality of nursing homes, and insufficient multidisciplinary governance collaboration. Prime: Health promotion for preventing age-related illness is required to preserve health in old age, and full-time family caregivers' psychological well-being is often overlooked.

    This study aimed to assess the knowledge of the Malaysian public on the coronavirus disease 2019 (COVID-19) and antibiotics, the practice of preventive measures and attitude towards the new norms. The web-based questionnaire was disseminated online from 1 to 31 October 2020. Out of 2117 respondents, 1405 (66.4%) knew that transmission of COVID-19 virus could happen in asymptomatic people. In term of antibiotics knowledge, 779 (36.8%) respondents were aware that taking antibiotics could not speed up the recovery process of all infections. Less than half of the respondents (49.0%) knew that antibiotics are effective against bacterial infection only. Majority (92.3%) practiced good preventive measures. Majority of the respondents strongly agreed that quarantine should be made mandatory for all arrival from overseas (97.2%) and wearing face masks should be made mandatory in all public areas (94.0%). Respondents of Chinese ethnicity (p = 0.008), middle-aged (p = 0.002), with tertiary education (p = 0.015) and healthcare related education (p < 0.001), from the higher income groups (p = 0.001) were more likely to have better knowledge on COVID-19. The Malaysian public demonstrated good knowledge towards COVID-19, adequate practice of preventive measures and high acceptance towards the new norm. Knowledge on antibiotics use and resistance was poor, which warrants attention from the health authorities.

    Background: Unsafe blood products may cause transfusion-transmissible infections. This study aimed to evaluate the knowledge and perceptions of blood donors regarding blood safety.

    Methods: This was a cross-sectional study conducted in the Kelantan state of Malaysia. The questionnaire comprised 39 questions that covered areas such as donors' social demographic information, knowledge of transfusion-transmitted diseases, blood screening and donor eligibility and perceptions towards blood safety. The knowledge score was categorised as good or poor.

    Results: Of the 450 distributed questionnaires, 389 were suitable for analysis. Only 18.5% of the donors had good knowledge, with 81.5% having poor knowledge. Less than 30% were aware that people with multiple sexual partners, bisexual people and male homosexual people are permanently deferred from blood donation. Only 29.4% agreed that donors are responsible if their blood causes infection. Furthermore, 39.3% assumed that they could check their HIV status through blood donation, and 10.3% and 5.4% of the respondents believed that donors are free from infection if they wear a condom during sex or only have oral sex when involved in prostitution, respectively.

    Conclusion: Poor knowledge and notable misperceptions concerning safe blood donation were found among blood donors. The Ministry of Health should incorporate safe blood education in future public awareness programmes.

    The aim of this cross-sectional study was to evaluate the knowledge and attitudes concerning antibiotic use and resistance among members of the local community in Pulau Pinang, Malaysia. The study was conducted among 326 residents of the Jelutong district, Pulau Pinang state, from August to October 2013. A self-administered five-part questionnaire was used for the data collection. The respondents exhibited inadequate knowledge of antibiotics in general. Approximately 80% of them did not know the indications for antibiotic use, while 76% believed that antibiotics were useful in terms of resolving viral fever. Additionally, 52.6% believed that antibiotics could be used to treat all types of infections. Inadequate knowledge of antibiotic resistance was also evident among the respondents, since 72.9% of them did not agree that resistant bacteria can spread from human or animal to human, while 32% were unaware that bacteria can develop resistance to antibiotics. More than 60% of respondents admitted that they took antibiotics in order to accelerate their recovery from illness, while 34.8% claimed that they only stopped taking antibiotics when they felt better. The findings hence indicate that most respondents had poor knowledge and attitudes concerning antibiotic use and resistance, which suggests the need for more community-based educational campaigns designed to improve the public's knowledge and attitudes regarding antibiotics.

    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.

    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.
