Abstract

Background

This study analyzes the epidemiological characteristics, investigation, and management of a tuberculosis (TB) outbreak in July 2024 at a psychiatric hospital in Yantai City, Shandong Province. It aims to provide recommendations for the prevention and control of TB in high-risk settings, such as psychiatric hospitals.

Methods

An epidemiological investigation was conducted, involving case analyses, symptom screenings, tuberculin skin tests (TST), chest X-rays (CXR), and an evaluation of the outbreak's progression and findings.

Results

Four active pulmonary TB cases were confirmed between July 3 and July 12, 2024. Among 313 contacts screened, 37 tested positive, with healthcare workers showing a higher positivity rate (18.60 %) compared with patients with mental illnesses (9.05 %). Healthcare workers’ close contacts had significantly higher positivity rates than their casual contacts.

Conclusions

The primary cause of this cluster outbreak was delayed outbreak alerts following the identification of the index case. To enhance outbreak prevention, medical institutions should clarify whether TB patients with a history of mental illness have been admitted in psychiatric hospitals and, if so, initiate timely outbreak alerts. Additionally, psychiatric hospitals should improve healthcare worker training to recognize TB symptoms and promptly report cases involving patients with mental illnesses.

2024年山东省某精神病院聚集性肺结核疫情分析

本研究分析了山东省烟台市某精神病院于2024年7月发生的一起结核病暴发的流行病学特征、调查和处理方法。它旨在为预防和控制高风险环境中的结核病提供建议，例如精神病院。方法开展流行病学调查，包括病例分析、症状筛查、结核菌素皮肤试验（TST）、胸部x光片（CXR）以及疫情进展和结果评估。结果2024年7月3日至7月12日共确诊活动性肺结核4例。在筛查的313名接触者中，37人检测呈阳性，卫生保健工作者的阳性率（18.60%）高于精神疾病患者（9.05%）。医护人员密切接触者的阳性率明显高于普通接触者。结论本次聚集性暴发的主要原因是在确定指示病例后延迟了暴发警报。为了加强疫情预防，医疗机构应澄清是否有精神病史的结核病患者曾入住精神病院，如果有，应及时发出疫情警报。此外，精神病院应加强卫生保健工作者的培训，以识别结核病症状并及时报告涉及精神疾病患者的病例。
