ABSTRACT Background: The cholelithiasis is disease of surgical resolution with about 60,000 hospitalizations per year in the Sistema Único de Saúde (SUS - Brazilian National Health System) of the Rio Grande do Sul state. Aim: To describe the profile of hospitalizations for cholecystitis and cholelithiasis performed by the SUS of Rio Grande do Sul state, 2011-2013. Methods: Hospital Information System data from the National Health System through morbidity list for cholelithiasis and cholecystitis (ICD-10 K80-K81). Variables studied were sex, age, number of hospitalizations and approved Hospitalization Authorizations (AIH), total amount and value of hospital services generated, days and average length of stay, mortality, mortality and case fatality ratio, from health regions of the Rio Grande do Sul. Results: During 2011-2013 there were 60,517 hospitalizations for cholecystitis and cholelithiasis, representing 18.86 hospitalizations per 10,000 inhabitants/year, most often in the age group from 60 to 69 years (41.34 admissions per 10,000 inhabitants/year) and female (27.72 hospitalizations per 10,000 inhabitants/year). The fatality rate presented an inverse characteristic: 13.52 deaths per 1,000 admissions/year for males, compared with 7.12 deaths per 1,000 admissions/year in females. The state had an average total amount spent and value of hospital services of R$ 16,244,050.60 and R$ 10,890,461.31, respectively. The health region "Capital/Gravataí Valley" exhibit the highest total expenditure and hospital services, and the largest number of deaths, and average length of stay. Conclusion: The hospitalization and lethality coefficients, the deaths, the length of stay and spending related to admissions increased from 50 years old. Females had a higher frequency and higher values spent on hospitalization, while the male higher coefficient of mortality and mean hospital stay.

摘要

背景：胆石症属于需外科干预的疾病，在巴西南里奥格兰德州的巴西国家卫生系统（Sistema Único de Saúde，简称SUS）中，每年约有6万人次因该病住院治疗。

研究目的：描述2011-2013年巴西南里奥格兰德州国家卫生系统收治的胆囊炎与胆石症患者的住院特征。

方法：采用巴西国家卫生系统医院信息系统中针对胆石症与胆囊炎（国际疾病分类第10版ICD-10编码K80-K81）的发病数据。本次研究纳入的变量包括：性别、年龄、住院次数与核准住院授权书（AIH）数量、住院服务产生的总金额与单笔均额、住院总天数与平均住院时长、死亡率与病死率，以及南里奥格兰德州各卫生区域的相关统计数据。

结果：2011-2013年间，全州共计收治胆囊炎与胆石症住院病例60517例，年均每万居民中约有18.86人次住院；高发年龄段为60~69岁组（年均每万居民41.34人次），女性患者住院率更高（年均每万居民27.72人次）。病死率存在显著性别差异：男性每千住院人次年死亡13.52例，女性则为7.12例。全州住院服务总支出与单次均额分别为16244050.60雷亚尔与10890461.31雷亚尔。其中“首都/格拉瓦泰伊谷”卫生区域的住院服务总支出、死亡病例数与平均住院时长均居全州首位。

结论：与该病住院相关的住院率、病死率、死亡例数、住院时长及医疗支出均自50岁起随年龄增长而升高。女性患者的住院频次更高、住院总支出更大，而男性的病死率与平均住院时长更高。
