Prehospital care is defined as any medical attention provided outside the hospital environment. This study aims to study the operation of a regional SAMU by assessing electronic records of cases managed and to evaluate demand patterns over time.
A retrospective, cross-sectional study was conducted through an analysis of emergency calls handled between the years of 2009 and 2013 by the SAMU Metropolitan 2 Region mobile emergency care service, located in Niterói, Brazil. Nonparametric tests were used to evaluate differences in the variables of interest between the two halves of the 5-year period of analysis and annually.
The total call volume during the period of analysis was 590,902 (monthly mean [SD], 9848 [3764]; 95%CI = 8875 to 10,820). Analysis of calls over time revealed a significant decline in call volume (p = 0.008), mainly between the year 2009 and subsequent years (p < 0.001). The vast majority of patients were adults with clinical conditions (average = 2311). Predominantly, calls were made to request prehospital assistance at the patient's home, and the most prevalent age range was 41-50 years.
The SAMU Metropolitan 2 regional emergency medical service predominantly attended to middle-aged women at their homes. Total call volume has been decreasing, perhaps reflecting a multifactorial phenomenon and improvements in the primary health care network.
院前护理被定义为在医院环境之外提供的任何医疗护理。本研究旨在通过评估所管理病例的电子记录来研究区域紧急医疗救护中心（SAMU）的运作情况，并评估随时间变化的需求模式。
通过分析位于巴西尼泰罗伊的大都会2区移动紧急医疗服务中心（SAMU）在2009年至2013年期间处理的紧急呼叫进行了一项回顾性横断面研究。使用非参数检验来评估分析的5年期间的前半段和后半段以及每年之间感兴趣变量的差异。
分析期间的总呼叫量为590,902次（每月平均值[标准差]，9848次[3764次]；95%置信区间=8875至10,820次）。对随时间的呼叫分析显示呼叫量显著下降（p = 0.008），主要是在2009年及随后几年之间（p < 0.001）。绝大多数患者是患有临床疾病的成年人（平均=2311人）。主要是在患者家中拨打请求院前援助的电话，最常见的年龄范围是41 - 50岁。
大都会2区区域紧急医疗服务中心主要为在家中的中年女性提供服务。总呼叫量一直在下降，这可能反映了一种多因素现象以及初级卫生保健网络的改善。
