Healthcare costs associated with progressive diabetic retinopathy among National Health Insurance enrollees in Taiwan, 2000-2004

<p>Abstract</p> <p>Background</p> <p>Diabetic retinopathy is one of the most common microvascular complications of diabetes and one of the major causes of adult visual impairment in national surveys in Taiwan. This study aimed to identify the healthcare costs of Taiwan's National Health Insurance program on behalf of diabetic patients with stable or progressive retinopathy.</p> <p>Methods</p> <p>A retrospective cohort study was conducted with 4,988 medication-using diabetic retinopathy subjects ≥ 40 years of age under National Health Insurance Program coverage between 2000 and 2004. Study cohort subjects were recorded as having diabetic retinopathy according to ICD-9-CM codes. States of diabetic retinopathy were strategically divided into stable and progressive categories according to subjects' conditions at follow-up in 2004. Expenditures were calculated and compared for the years 2000 and 2004.</p> <p>Results</p> <p>During the 4-year follow-up (2000 through 2004), 4,116 subjects (82.5%) of 4,988 diabetic subjects were in the stable category, and 872 (17.5%) were in the progressive category. Average costs of those in the normal category increased by US $48 from US$1921 in 2000 to US $1969 in 2004 (p = 0.594), whereas costs for those progressing from normal to non-proliferative diabetic retinopathy (NPDR) or proliferative diabetic retinopathy (PDR) increased by US$1760, from US $1566 in 2000 to US$3326 in 2004 (p < 0.001). The PDR category had the highest average costs at US $3632 in 2000. The NPDR-to-PDR category experienced the greatest increase in costs at US$3482, from US $2723 in 2000 to US$6204 in 2004 (p = 0.042), and the greatest percentage of increase at 2.3% (2.2% when adjusted by comparing to normal category).</p> <p>Conclusions</p> <p>This large-scale longitudinal study provides evidence that increased healthcare costs are associated with progressive diabetic retinopathy among diabetic NHI enrollees in Taiwan.</p

PCN102 THE BURDEN OF RENAL CELL CANCER: A RETROSPECTIVE LONGITUDINAL STUDY ON OCCURRENCE, OUTCOMES AND COST USING AN ADMINISTRATIVE CLAIMS DATABASE

AbstractObjectiveTo assess the burden of renal cell carcinoma (RCC) in epidemiologic and economic terms.MethodsRetrospective, naturalistic longitudinal study on the occurrence, outcomes and cost of RCC using an administrative database.We selected residents of Friuli-Venezia-Giulia (FVG), a North-eastern Region of Italy, who had a RCC first hospital admission during the period 2000–2004, and we followed them up until: 30th June 2005, death or transfers. Direct medical costs were quantified in the perspective of FVG Regional Health Service.ResultsWe enrolled 1358 patients (63% male), the 18.8% presenting a metastatic-stage, leading to a crude incidence of 23/100.000 person-years. During the follow-up, 76% of the metastatic patients and 21% of the non-metastatic patients died.Total health care costs per-patient over the maximum of follow-up were 16,090€ for the localised stage group and 17,656€ in the metastatic-stage group.DiscussionRCC imposes a significant epidemiologic and economic burden to the healthcare-system and the society
