Urinary tract infection (UTI) is common in long-term care (LTC) residents; however, most infections are asymptomatic and do not require treatment. Differentiating asymptomatic from symptomatic UTI is challenging, because LTC residents typically have chronic genitourinary complaints, multiple comorbid illnesses, and communication barriers. Although consensus guidelines have been proposed to improve the accuracy of identifying symptomatic UTIs and minimize treatment of asymptomatic UTIs, diagnostic accuracy is not yet optimized. Strategies for prevention of UTI are unsatisfactory and require further study; nevertheless, there is some evidence for the efficacy of cranberry products and vaginal estrogen to prevent recurrent UTI in women.
尿路感染（UTI）在长期护理（LTC）居民中很常见；然而，大多数感染是无症状的，不需要治疗。区分无症状和有症状的 UTI 具有挑战性，因为 LTC 居民通常有慢性泌尿生殖系统投诉、多种合并疾病和沟通障碍。尽管已经提出了共识指南来提高识别有症状 UTI 的准确性并最大限度地减少无症状 UTI 的治疗，但诊断准确性尚未得到优化。UTI 的预防策略并不令人满意，需要进一步研究；然而，有一些证据表明蔓越莓产品和阴道雌激素可有效预防女性复发性 UTI。
