METHODS: This retrospective chart review involved dengue patients with dengue non-structural protein 1 (NS1) antigen positivity admitted to a tertiary hospital in Malaysia from January to July 2015. A comparison was made between older people (aged ≥60 y) and others.
RESULTS: Among 406 dengue patients, 43 (10.6%) were older people. Older dengue patients were less likely to present with persistent vomiting (adjusted OR [AOR] 0.247, 95% CI 0.093 to 0.656, p=0.005), while restlessness and confusion were more common at presentation (AOR 3.356, 95% CI 1.024 to 11.003, p=0.046). Older patients had significantly lower albumin upon admission (38 vs 40 g/L, p=0.036) and during hospital stay (35 vs 37 g/L, p=0.015). Compared with younger patients, older patients were more likely to have experienced nadir platelet counts of <50×109/L (AOR 2.897, 95% CI to 1.176 to 7.137, p=0.021). They were also more likely to require an extended hospital stay (AOR 3.547, 95% CI 1.575 to 7.986, p=0.002).
CONCLUSIONS: Diagnosis of dengue in older people may be challenging because of atypical presentations. Increased vigilance is necessary as there is an increased tendency to develop severe thrombocytopenia, hypoalbuminemia and prolonged hospitalisation in older people.
METHODS: This is a cross-sectional study of seatbelt compliance of patients aged over 18 years, attending the emergency departments of five public hospitals in Singapore after road collisions from 2011-2014. Seatbelt data was obtained from paramedic and patient history.
RESULTS: There were 4,576 patients studied. Most were Singapore citizens (83.4 %) or permanent residents (2.4 %), with the largest non-resident groups from Malaysia, India, and China. Overall seatbelt compliance was 82.1 %. On univariate analysis, seatbelt compliance was higher in older patients (OR 1.02, 95 % CI 1.001-1.021, p
