The latest edition of the Open Drug Scenes Survey in Brazilian Cities (LECUCA) investigated social vulnerability, health, and the use of the Psychosocial Care Network by attendees of open drug scenes (ODSs) involving crack cocaine in São Paulo, Fortaleza, and Brasília between 2021/2022.
Since 2016, LECUCA has used Time-Location Sampling (TLS) to select probabilistic samples representative of the population of ODS attendees.
We interviewed 579 participants in São Paulo, Fortaleza, and Brasília, obtaining a response rate of 75%. We found no difference in ODS attendees regarding the prevalence of sociodemographic indicators and time living in the ODS. The prevalence values of attendees who had never been homeless before living in the ODS and those living in their homes were equally high in the three capitals. Fortaleza stood out for having lower rates of homelessness and limited access to specialized health services, whereas Brasília had high rates of searching for emergency services due to drug use and greater access to all modalities of health and assistance services. Unprotected sex was prevalent over one third of ODSs attendees, and none of the capitals had more than half of the attendees testing for tuberculosis and sexually transmitted infections. Rates of pregnancy complications were high in all three capitals, with São Paulo accounting for the lowest rates.
LECUCA provides significant subsidies to governmental and institutional managers, aiming at catalyzing the formulation of public policies and care strategies based on data and evidence.
最新版的巴西城市开放毒品场景调查（LECUCA）在2021年至2022年期间，对圣保罗、福塔莱萨和巴西利亚涉及可卡因的开放毒品场景（ODS）参与者的社会脆弱性、健康状况以及心理社会护理网络的使用情况进行了调查。
自2016年以来，LECUCA一直采用时间-地点抽样（TLS）来选择代表ODS参与者群体的概率样本。
我们在圣保罗、福塔莱萨和巴西利亚采访了579名参与者，回复率为75%。我们发现，在社会人口统计学指标的患病率和在ODS中的居住时间方面，ODS参与者没有差异。在三个首都城市中，在进入ODS之前从未无家可归的参与者和居住在家中的参与者的患病率同样高。福塔莱萨的突出特点是无家可归率较低，获得专业医疗服务的机会有限，而巴西利亚因吸毒寻求紧急服务的比例较高，获得各种医疗和援助服务的机会更多。超过三分之一的ODS参与者存在无保护性行为，没有一个首都城市超过一半的参与者接受结核病和性传播感染检测。所有三个首都城市的妊娠并发症发生率都很高，其中圣保罗的发生率最低。
LECUCA为政府和机构管理人员提供了重要的补贴，旨在促进基于数据和证据制定公共政策和护理策略。
