This study aims to identify the influencing factor towards the intention to donate blood using the Theory of Planned Behaviour (TPB) model among healthcare workers (HCWs). A random sample of 400 HCWs from the population received the survey via a web-based link. The hypothesised model was tested using structural equation modelling. The median (interquartile range) age of respondents was 31.0 (11.0) years with female accounting for 75.5% (n = 302). Overall, 60.3% (n = 241) have donated blood. The final structural model showed a good fit of the data: CFI = 0.972; TLI = 0.976; RMSEA = 0.052; SRMR = 0.064. Perceived behavioural control and age significantly influenced the HCW's intention to donate blood. The final model explained 43% of the total variance in intention to donate blood. The findings provide a vital message to focus on some barriers and motivational factors of blood donation behaviour among HCWs.
Field tests were conducted to compare the degree of protection from bites of Mansonia species and Anopheles maculatus by applying two repellent/insecticidal bars, MOSBAR and MOSKIL, to exposed arms and legs. Human test subjects were exposed to natural populations of mosquitos for an 8-hour night time period while using the repellent/insecticidal bars. MOSBAR gave good protection against the bites of Mansonia and An. maculatus. MOSKIL was effective against An. maculatus but not against Mansonia. High mortality was observed among the mosquitos collected from human test subjects treated with the repellent/insecticidal bars. Use of MOSBAR in terms of cost-effectiveness and safety by field and health workers entering into malaria and filariasis endemic areas is discussed.
Background Appropriate antimicrobial prescribing in the emergency department (ED) is a challenge due to diagnostic uncertainty, time pressure, and clinical inertia. Objective To assess the appropriateness of antimicrobial prescribing in the ED. Setting This study was conducted in the inpatient ED of a tertiary hospital in Malaysia. Method We conducted a 6-month retrospective antimicrobial prescriptions analysis among ED patients who received intravenous antimicrobial. Antimicrobial prescriptions of conveniently selected adult patients were evaluated with the medication appropriateness index. Main outcome measure Appropriateness of antimicrobial prescribing was the primary outcome measure. Results We analysed 310 patients with 326 antimicrobial prescriptions. Ceftriaxone (41.1%, n = 134) and amoxicillin-clavulanate (36.5%, n = 119) were the most common antimicrobials prescribed. Respiratory infections (71.5%, n = 233) was the main indication for antimicrobial therapy in the ED. All antimicrobials prescribed were indicated as per the Malaysian antimicrobial guidelines. The overall rate of inappropriate antimicrobial prescribing was 53.1% (n = 173). Thirty-two (9.8%) antimicrobials were prescribed with inappropriate doses; the majority was related to beta-lactam/beta-lactamase dose (p = 0.002). One hundred and forty-three (43.9%) antimicrobials prescribed had alternatives with similar efficacy but were less costly; which referring to ceftriaxone usage (p
