Using interrupted time-series analysis and National Health Insurance data between January 2000 and August 2003, this study assessed the impacts of the severe acute respiratory syndrome (SARS) epidemic on medical service utilization in Taiwan. At the peak of the SARS epidemic, significant reductions in ambulatory care (23.9%), inpatient care (35.2%), and dental care (16.7%) were observed. People's fears of SARS appear to have had strong impacts on access to care. Adverse health outcomes resulting from accessibility barriers posed by the fear of SARS should not be overlooked.
OBJECTIVEThe discrepancy of diabetes incidence and care between socioeconomic statuses has seldom been studied concurrently in nations with universal health coverage. We aimed to delineate whether income disparity is associated with diabetes incidence and inequality of care under a national health insurance (NHI) program in Asia.RESEARCH DESIGN AND METHODSFrom the Taiwan NHI database in 2000, a representative cohort aged ≥20 years and free of diabetes (n = 600,662) were followed up until 2005. We regarded individuals exempt from paying the NHI premium as being poor. Adjusted hazard ratios (HRs) were used to discover any excess risk of diabetes in the poor population. The indicators used to evaluate quality of diabetes care included the proportion of diabetic patients identified through hospitalization, visits to diabetes clinics, and completion of recommended diabetes tests.RESULTSThe incidence of type 2 diabetes in the poor population was 20.4 per 1,000 person-years (HR, 1.5; 95% CI, 1.3–1.7). Compared with their middle-income counterparts, the adjusted odds ratio (OR) for the poor population incidentally identified as having diabetes through hospitalization was 2.2 (P < 0.001). Poor persons with diabetes were less likely to visit any diabetes clinic (OR, 0.4; P < 0.001). The ORs for the poor population with diabetes to receive tests for glycated hemoglobin, low-density lipoprotein cholesterol, triglycerides, and retinopathy were 0.6 (0.4–0.9), 0.4 (0.2–0.7), 0.5 (0.4–0.8), and 0.4 (0.2–0.9), respectively.CONCLUSIONSPoverty is associated not only with higher diabetes incidence but also with inequality of diabetes care in a northeast Asian population, despite universal health coverage.
Background and Purpose-The occurrence of preeclampsia-eclampsia during pregnancy has been reported to increase the risk of stroke in mainly Western populations. However, few studies have evaluated stroke risk in Asian populations and followed women beyond the early postpartum period. Thus, the present study determined the risk of stroke in women in Taiwan during pregnancy and the first postpartum year. Methods-A population-based cohort study was performed on 1 132 019 parturients during 1999 to 2003 using a dataset linking birth certificates and National Health Insurance hospital discharge data. Stroke-free survival rates were estimated using the Kaplan-Meier method, and the log-rank test was used to examine the effect of preelampsia-eclampsia on the prevalence of stroke. Sociodemographic factors and obstetric complications were used in multivariate logistic regression models to determine the adjusted odds ratios of preeclampsia-eclampsia on the risk of hemorrhagic and ischemic stroke during pregnancy and within the first postpartum year. Results-The incidence of stroke was 21.47 cases per 100 000 deliveries. There were 139 cases of hemorrhagic stroke and 107 cases of ischemic stroke. The respective adjusted relative risk of preeclampsia-eclampsia for hemorrhagic and ischemic stroke were 10.68 (95% CI, 3.40 to 33.59) and 40.86 (95% CI, 12.14 to 137.47) within 3 months antepartum; 6.45 (95% CI, 1.42 to 29.29) and 34.71 (95% CI, 11.08 to 108.68) in the first 3 days postpartum; 5.61 (95% CI, 0.71 to 44.10) and 11.23 (95% CI, 2.45 to 51.59) from 3 days to 6 weeks postpartum; 11.76 (95% CI, 4.05 to 34.11) and 11.60 (95% CI, 3.30 to 40.82) from 6 weeks to 6 months pospartum; and 19.90 (95% CI, 7.75 to 51.11) and 4.35 (95% CI, 0.58 to 32.92) from 6 months to 12 months postpartum. Conclusions-Women with preeclampsia-eclampsia have a significantly higher risk of stroke during pregnancy and in the first postpartum year. These results suggest that women with preeclampsia-eclampsia should be closely monitored even after pregnancy.
