RESUMO
Up-to-date data on the burden of disease are important to identify patients with unmet needs and to optimize healthcare resources. We aimed to characterize the burden of pneumonia hospitalizations in Hong Kong and inform targeted healthcare policies for pneumonia control in the era of global aging. This was a population-based study using a territory-wide administrative electronic health record system that covers all public hospitals of Hong Kong. Patients admitted to public hospitals, from 2011 to 2015, with a diagnosis of pneumonia at discharge were identified based on the International Classification of Diseases-Ninth Revision-Clinical Modification Codes (480-486 and 487.0). Incidence, inpatient case-fatality, all-cause fatality, 28-day readmission, hospital length of stay, and healthcare costs were assessed for seven age strata. We identified 323,992 patients (median age 80 years, 44.4% female) with hospitalized pneumonia (organism unspecified 84.2%; bacterial pneumonia 12.3%; viral pneumonia 2.5%; others 1.0%). Annual incidence was 955.1 per 100,000 population, with a 10.6% decrease from 2011 to 2015. Case-fatality, all-cause fatality, and 28-days readmission risks were 13.8, 21.6, and 19.5%, respectively. The average hospital length of stay was 14.1 days with corresponding direct costs of $9348 USD per episode in the monetary value of 2015. Individuals aged ≥ 65 years accounted for over 75% of pneumonia-related hospitalizations, 90% of deaths, and the majority of healthcare costs. Hospitalized pneumonia represents a considerable health and economic burden in Hong Kong, especially in older adults. The study provides a population-level baseline estimate for further cost-effective evaluation of targeted strategies for pneumonia control.

PURPOSE: Antipsychotic-prescribing patterns remain unclear in Asia. The aims of our study were to investigate prescribing trends of antipsychotic medication in the general population, children, and older patients by drug generation (first or second), the prescribing trend in pregnant women, the probable indication for antipsychotic prescription, and the prescribing trend by dosage form. METHODS: This descriptive study identified and included all patients prescribed with antipsychotic in Hong Kong from 2004 to 2014 using the Clinical Data Analysis and Report System. This study calculated and reported the prevalence of antipsychotic prescribing in patient groups of interest, the percentage with diagnoses of mental disorders were derived, and the prevalence of antipsychotic by dosage forms. RESULTS: The study included 10 109 206 prescriptions of any antipsychotics to 256 903 patients. Over the study period, the prevalence of antipsychotic prescribing increased from 1.06% to 1.54% in the general population, from 0.10% to 0.23% in children (3-17 years old), and from 2.61% to 3.26% in older patients (≥65 years old). The prevalence of second-generation antipsychotics increased, but the prevalence of first-generation antipsychotics did not. Prevalence of antipsychotic prescribing in prepregnancy, pregnancy, and postpartum timeframes varied from 0.18% to 0.38%. The percentage of incident prescriptions with a diagnosis of psychosis decreased from 54.1% to 47.5%. CONCLUSIONS: Antipsychotics have been increasingly prescribed in the general population, children, and older patients. There is an increase in second-generation antipsychotic prescribing. Over half of incident users had a recent diagnosis of a nonpsychotic mental disorder in 2014, suggesting that off-label prescribing of antipsychotics might be common.
