1998年臺灣地區全民健保高血壓病患之人口學特徵與用藥情形

Demographic and Descriptive Analyses of Anti-hypertensive Prescriptions in 1998: Data from Taiwan’s National Health Insurance Program

經由分析1998年全民健保資料，來探討國人高血壓人口學特徵以及用藥情形，並比較不同年齡層與性別間的差異，及接受治療之情形。相關數據資料之取得，來自中央健康保險局之健保資料庫，涵蓋台灣二千一百萬人民的看診資料。期間自1997年7月1日至1998年6月30日，選取診斷為高血壓的所有案例與其處方，將轉碼後之身份證號碼歸戶之後，針對性別與年齡層等分層資料，進行描述性分析。本研究期間內共收集9,539,757筆高血壓門診處方，總計有16,303,791筆降血壓藥物資料，共有937,514人。由研究結果發現，不論男或女，19至44歲之服藥率皆約為1%，45-64歲女性上升至12.5%，大於65歲女性則上升至25%；男性則為10%、30%。至於當年之新服藥率女性45-64歲為7.4%，大於65歲為12.2%；男性為6.0%及14.6%。年平均領藥天數以大於65歲組最長，男性為110天，女性為100天；平均藥物種類大於65歲組之男女分別為1.65及1.6種；每日平均藥物粒數大於65歲組之男女分別為2.76及2.63粒。由這些結果得知高血壓患者的服藥率與新服藥率隨年齡增加而增加，而全年平均領藥天數僅約100天，有偏低之情形，如何使罹病的患者願意以及長期服藥，是防治高血壓之主要課題。

This study was aimed at analyzing demographic factors and prescription ratios as they pertain to the treatment hypertension via reimbursed data from Taiwan's National Health Insurance program. All ambulatory healthcare visits for the 21 million people in Taiwan were collected between 1 July 1997 to 30 June 1998 for research purposes by proper authority. Claims with the diagnosis of hypertension and for which anti-hypertensive medications were prescribed were included and reviewed using scrambled identification numbers. Demographic factors were included in the descriptive analysis. A total of 9,539,757 claims for hypertension were submitted by 937,514 beneficiaries, and 16,303,791 medications were analyzed. One percent of males and females, from 19 to 44 years of age, were prescribed anti-hypertensive medications. The ratio for females, 45-64 years of age, was 12.5%, and for those over 65 years of age, the ratio was 25%; for males, the same ratios were 10% and 30%, respectively. For new female patients, the ratio for those 45-64 years of age was 7.4% and for those over 65 years of age, the ratio was 12.2%; the corresponding male ratios were 6.0% and 14.6%, respectively. The average length of medication use in a year were longest for those 65 years of age and over: 110 days for males and 100 days for females. The mean number of different kinds of medication were 1.65 for males and 1.6 for females. The mean number of tablets of medication for those over 65 years of age were 2.76 for males and 2.63 for females. Medications for hypertensive patients increased as age increased, for both new and existing patients. The length of medication use was approximately 100 days, which seemed too short for the optimal treatment of hypertension. It is therefore crucial to ensure and enhance the compliance of treatment in hypertension patients.
