The objectives were to identify factors associated with early revisit of adult patients with acute asthma exarcebation discharged from the Emergency Department (ED). It was a retrospective cohort study with patients aged 12 years or more within a period of 1 month and who were treated for acute asthma and discharged from the ED of Sarawak General Hospital. A total of 397 patients fulfilled sampling criteria and out of this number, 13.9% had revisit to the ED within 2 weeks. In all of these revisit cases, 9.1% were actually admitted. Prescription rate of oral corticosteroid was found to be low (24.9%) and abscond rate was high (25.1%). Patients who absconded from the ED and their concurrent infection were associated with early ED revisit.

The popularity of ultrasound for acute diagnosis of fractures in the Emergency Department (ED) has increased over the recent years. This present study aimed to determine the sensitivity and specificity of ultrasound use for detection of fractures in a different environment, which is at the triage area of the ED. We compared the results of bedside ultrasound in detecting non-critical fractures to the current gold standard of X-rays in the triage area. The design was a single centered crosssectional study. From August 2014 till November 2014, a total of 46 patients were recruited, creating 75 image pairs. Following consent, a bedside ultrasound was performed and subsequently compared with X-ray reporting regarding the presence or absence of fractures. SPSS analysis was used to determine the sensitivity and specificity of ultrasound in diagnosing fracture as compared to X-rays. Ultrasound had a sensitivity of 72% (95% CI, 50.6% - 87.9%) and a specificity of 80% (95%CI: 66.3 – 90%) when compared to X-rays in fracture diagnosis. The kappa analyses showed moderate inter observer agreement (0.5) between ultrasound and X-rays in diagnosing fractures. This study suggests that the use of ultrasound as a triage tool yet has unacceptable sensitivity and needs further evaluation and consideration.

Midazolam is one of the most commonly used drugs for sedation in Emergency Department (ED). This was a retrospective study conducted on 380 patients from December 2012 to May 2014 in ED of Universiti Kebangsaan Malaysia Medical Centre (UKMMC). The objective was to elicit the frequency of side effects and correlation to various factors i.e. socio-demography, co-morbidities, age groups and underlying illnesses. Out of 380 patients, 35 patients experienced side effects (20 patients with midazolam alone, 15 patients with combination of drugs). The average age was 42 years and the average dose of midazolam was 3.5mg. The most common other drug combined was fentanyl. The overall complication rate for midazolam was 5.3%. The most common side effect recorded was excessive somnolence (1.6%). Other side effects included local skin reactions (1.1%), vomiting (0.8%), headache (0.8%) and hypotension (0.5%). There was no significant association between the socio-demographic factors and drugs combination with the side effects of midazolam on patients. It was concluded that midazolam was a safe drug due to absence of any life-threatening side effects. There are possibilities that most side effects recorded could be caused by other comfounding factors e.g. underlying injuries or disease and combination with other drugs.
