[Objective]To study the characteristics of osteoporotic hip fractures complicated with bronchiectasis(BE)for better periop-erative evaluation and management.[Methods]From January 2020 to October 2022,48 patients with bronchiectasis(the BE group)and 48 patients without BE(the non-BE group)were selected from those who underwent surgical treatment for osteoporotic hip fractures in our hos-pital.The impacts of BE were analyzed by univariate comparison,pairwise correlation analysis and binary logistic regression analysis.[Re-sults]The BE patients had significantly lower bone mineral density(BMD)T value[(-2.5±0.4)vs(-2.2±0.6),P=0.003]and vitamin D lev-els[(14.9±2.3)ng/ml vs(18.5±2.4)ng/ml,P＜0.001]than the non-BE group,whereas the former had significantly higher incidence of postop-erative acute pulmonary infection than the latter[cases(％),20(41.7)vs 5(10.4),P＜0.001],despite of no significant difference in mortality in a year postoperatively between them(P＞0.05).In term of stratified comparison in the BE patients:the patients with acute pulmonary in-fection had lower vitamin D levels,higher mortality in a year after surgery,and more severe bronchiectasis severity index(BSI)than those without acute pulmonary infection(P＜0.05).In addition,the death group had lower vitamin D level,longer bed rest time,more severe BSI grade and higher incidence of postoperative acute pulmonary infection than the alive group(P＜0.05).As for pairwise correlation,the BSI grade was negatively correlated with BMD and vitamin D levels,while positively correlated with bed rest duration(P＜0.05).As results of lo-gistic regression,the acute pulmonary infection(OR=9.16,P＜0.05)and intraoperative blood loss(OR=1.11,P＜0.05)were independent risk factors for death in one year after surgery,while high vitamin D levels may be a protective factor for death(OR=0.720,P＞0.05).[Conclu-sion]The patients with osteoporotic hip fracture complicated with BE usually have reduced bone mineral density and vitamin D levels,and are prone to acute pulmonary infection after surgery.The decrease of BMD and vitamin D levels are related to the BE severity.Postopera-tive acute pulmonary infection and intraoperative blood loss were independent risk factors for death in 1 year after surgery.
