ABSTRACT
OBJECTIVES:
We examined the existence and potential burden of seasonality of stroke admissions and mortality within a tropical climate using cohort data collected between 1â¯st November 2003 and 31â¯st October 2012. PATIENTS ANDMETHODS:
In a prospective cohort of hospitalised stroke patients from the catchment of â¼75 % of the Thai population (nâ¯=â¯569,307; mean SD ageâ¯=â¯64(14.5)), incident stroke admissions, in-hospital mortality, prolonged hospitalisations, and stroke related complications by season were determined. Rates of incident stroke admissions by month and season were plotted. Winter excess indexes for study outcomes expressed as a percentage were calculated. Using logistic regression we examined the association between winter admission and in-hospital mortality (non-winter admission as reference) adjusting for age, sex, stroke type, year of admission, and presence of pre-existing comorbidities.RESULTS:
We observed a winter excess in mortality during hospitalisation (+10.3 %) and prolonged length of stay (+7.3 %). Respective winter excess indexes for dyslipidaemias, arrhythmias, anaemia, and alcohol related disorders in patients that died during hospitalisation were +1.4 %, +6.2 %, +0.2 %, +1.5 %. In these patients, respective winter excess indexes for post-stroke complications of pneumonia and sepsis were +6.7 % and +3.2 %. In fully adjusted analyses, winter admission (compared to non-winter admission) was associated with increased odds of in-hospital mortality (OR (95 % CI)â¯=â¯1.023 (1.006-1.040)).CONCLUSIONS:
We provide robust evidence for the existence of an excess in winter stroke admissions and subsequent in-hospital deaths within a tropical region.Palavras-chave
