Background Fibrinolysis using streptokinase or tenecteplase remains the primary reperfusion strategy for ST-elevation myocardial infarction (STEMI) in many Asian countries, including Malaysia. Comparative outcomes of these two fibrinolytic agents in the Asian population were inconclusive despite being widely used. Aim We aimed to assess and compare the outcomes of streptokinase versus tenecteplase in STEMI reperfusion of an Asian population. Method This single-centre retrospective study analysed data on STEMI patients who received fibrinolytic therapy from 2016 to 2020 in the Emergency Department of the largest tertiary hospital in Malaysia. Total population sampling was used in this study. Based on the propensity score matching, 359 patients receiving streptokinase were matched against 359 patients receiving tenecteplase by incorporating 16 variables that potentially affect mortality. 30-day mortality, stroke and major bleeding were the primary outcome measures. Results There was no significant difference in 30-day mortality between streptokinase (n = 39, 11.2%) and tenecteplase (n = 46, 13.2%) groups (p = 0.418). The rates of ischemic strokes [streptokinase (n = 1, 0.3%) versus tenecteplase (n = 3, 0.9%), p = 0.624], intracranial haemorrhage [streptokinase (n = 3, 0.9%) versus tenecteplase (n = 1, 0.3%), p = 0.624] and major bleeding [streptokinase (n = 4, 1.1%) versus tenecteplase (n = 3, 0.9%), p = 0.624], were comparable for the two groups. The incidences of failed thrombolysis were significantly higher in the tenecteplase arm. Hypotension and allergic reaction were significantly higher in the streptokinase arm. Conclusion Streptokinase and tenecteplase are fibrinolytic agents with similar efficacy and safety in STEMI reperfusion therapy in our Asian population., (© 2022.

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 < 0.001). Conclusions The inappropriate antimicrobial prescribing in the emergency department is prevalent. This emphasises the importance of conducting antimicrobial stewardship initiative in the ED to improve the appropriate dosing of beta-lactam/beta-lactamase inhibitors as well as the judicious use of ceftriaxone., (© 2021.
