Psoas abscess (PA) is an uncommon disease. Although PA is associated with significant morbidity and mortality, its epidemiology and clinical characteristics remain unknown. This study aimed to evaluate the epidemiological and clinical features and outcomes of patients with PA in a prefectural-wide study.
This was a multicenter retrospective cohort study conducted between 2010 and 2012 in the Miyagi prefecture with a population of 2,344,062 in 2011. Adult patients with PA were enrolled from 71 secondary and tertiary care hospitals.
There were 57 patients with adult PA in the Miyagi prefecture. The median age of the patients was 72 years, and 67% patients were male. Fever and flank pain were the primary symptoms in 82% and 74% of patients, respectively. Ten patients (18%) had septic shock, and the hospital mortality rate was 12%. Secondary PA was present in 72% of cases, and the most common origin was pyogenic spondylitis. Of the patients with secondary PA, 44% had an epidural abscess. The most common pathogens were , and 11% (6 cases) of the cases were caused by methicillin-resistant .
In the Miyagi prefecture of Japan, the estimated prevalence of PA was 1.21/100,000 population years and hospital mortality was 12%. Secondary PA accounted for more than 70% of the cases, and was the most common causative pathogen.
腰大肌脓肿（PA）是一种罕见疾病。尽管PA与显著的发病率和死亡率相关，但其流行病学和临床特征仍不清楚。本研究旨在通过一项全县范围的研究评估PA患者的流行病学、临床特征及预后。
这是一项多中心回顾性队列研究，于2010年至2012年在宫城县开展，2011年该县人口为2344062。成年PA患者来自71家二级和三级医疗机构。
宫城县有57例成年PA患者。患者的中位年龄为72岁，67%为男性。发热和侧腹痛分别是82%和74%患者的主要症状。10例患者（18%）发生感染性休克，医院死亡率为12%。72%的病例为继发性PA，最常见的病因是化脓性脊柱炎。在继发性PA患者中，44%有硬膜外脓肿。最常见的病原体是 ，11%（6例）病例由耐甲氧西林 引起。
在日本宫城县，PA的估计患病率为1.21/10万人口年，医院死亡率为12%。继发性PA占病例的70%以上， 是最常见的致病病原体。
