ABSTRACT
Background: Given the deficits in allergists and testing capacity, the diagnosis of drug allergy is largely dependent on the clinician's and pharmacist's judgment. The ability to recognize drug allergies and respond appropriately is crucial to patient safety. Currently, there is a void in the evidence that limits the ability to recommend comprehensive and swift improvements on this front. Objective: This study thus aimed to evaluate the knowledge, attitude, and practice toward drug allergy among doctors and pharmacists working in public healthcare facilities in Sabah, Malaysia. Methods: This cross-sectional study was conducted in 24 hospitals and 11 clinics in Sabah. A validated Drug Allergy Knowledge, Attitude, and Practice Questionnaire was adapted from a published study and developed on an online survey platform. The questionnaire was distributed to all listed eligible respondents via email and personal messenger service. Results: A total of 549 doctors and pharmacists responded, with an overall response rate of 18.2%. The total mean knowledge, attitude, and practice scores were 8.3 (SD, 1.98), 18.9 (SD, 2.55), and 17.3 (SD, 4.4), respectively. It was found that pharmacists performed significantly poorer than both medical officers (mean score difference = -0.5; P = 0.006) and specialists (mean score difference = -0.9; P = 0.020) in the knowledge domain. As the time in service doubles, the knowledge score increases significantly by 0.3 (P = 0.015). Conclusion: Knowledge, attitude, and practice on drug allergy among doctors and pharmacists in Sabah were poor. It is thus timely for advanced educational programs on drug allergy to be formalized and implemented.
ABSTRACT
INTRODUCTION: Older adults are among the most vulnerable groups during the COVID-19 epidemic, contributing to a large proportion of COVID-19-related death. Medication review and reconciliation by pharmacist can help reduce the number of potentially inappropriate medications but these services were halted during COVID-19. AIM: To assess the prevalence and factors associated with inappropriate medicine use among older populations with COVID-19. METHODS: This was a cross-sectional, retrospective analysis of medications among hospitalized older adults with COVID-19. Potentially inappropriate medication use was categorized using the Beer's and STOPP criteria. RESULTS: Combining both criteria, 181 (32.7%) of the 553 patients were identified to have used at least one or more potentially inappropriate medication. A marginally higher number of inappropriate medications was documented using the Beers 2019 criteria (151 PIM in 124 patients) compared to STOPP criteria (133 PIMS in 104 patients). The long-term use of proton pump inhibitors (n = 68; 12.3%) and drugs which increases the risk of postural hypotension were the most commonly reported PIM (n = 41; 7.4%). Potentially inappropriate medication use was associated with previous history of hospital admission in the past 12 months (Odds ratio [OR]: 2.27; 95% CI 1.29-3.99) and higher number of discharge medications. CONCLUSIONS: Nearly, one in three older adults with COVID-19 had been prescribed a PIM, and the proportion of older adults with polypharmacy increased after discharge. This highlights the importance of having clinical pharmacist conducting medication reviews to identify PIMs and ensure medication appropriateness.
ABSTRACT
Introduction: Oral anticoagulant is essential for the treatment and prevention of thromboembolism. Warfarin is an effective oral anticoagulant in prevention and treatment of thromboembolism. However, warfarin is frequently associated with adverse event (AE) requiring hospitalization. Method: We performed a retrospective cohort study of all patients admitted to a large tertiary public hospital for warfarin-related AEs. Patients were grouped based on bleeding severity and the direct medical cost was also calculated. Results: During the 4 years study period, a total of 224 patients were admitted for warfarin-related AEs. Mean age of patients admitted was 65.1 years (standard deviation [SD] = 11.5). More than half, 59.6%, of them were on warfarin for prevention of stroke in atrial fibrillation or atrial flutter. Major bleeding occurred among 50.9% of the patients with gastrointestinal bleed, 34 (29.8%), as the common site of bleed. Patients with major bleed had longer median hospital stay of 4 days (interquartile range [IQR] = 5) compared to 3 (IQR = 3) days in non-major bleed. There were 17 (14.9%) death among the major bleeders. Mean medical cost for managing warfarin-related AEs was USD 708.08. Conclusion: The admitted patients were equally distributed in terms of bleeding severity. Medical cost incurred for managing warfarin-related AEs increased with the severity of bleeding.
ABSTRACT
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 < 0.001). CONCLUSION: The educational leaflet was able to address salient knowledge gaps in the participants and remained sustainable over a two-week follow-up. Thus, its inclusion into future antibiotic awareness campaigns should be encouraged.
