Reduction in the incidence of pneumonia in elderly patients after hip fracture surgery: An inpatient pulmonary rehabilitation program.

Hip fracture is an important health care issue in the elderly. Postoperative pulmonary complications occur in 4% of patients after hip fracture surgery. However, previous research is limited regarding pulmonary rehabilitation in this group. In this study, we present clinical evidence regarding the impact of a comprehensive pulmonary rehabilitation program in elderly hip fracture patients after hip surgery.We designed a nonrandomized, Quasi-experimental study, comparing 2 sequential time periods in the same center. Elderly patients (≥65 years) with a new hip fracture from February 1, 2014 to December 31, 2015 and who were willing to undergo a postoperative pulmonary rehabilitation program were enrolled. The pulmonary rehabilitation program started on January 1, 2015. Patients who refused rehabilitation or did not receive a surgical intervention were excluded. Patients received either standard care (standard care group) or standard care plus the postoperative rehabilitation program (intervention group).A total of 240 patients (163 women and 77 men) were enrolled, including 138 in the standard care group and 102 in the intervention group. The intervention group had a significantly lower incidence of pneumonia (6 patients, 5.9%) compared to the standard care group (19 patients, 13.9%). An age >80 years, cancer status, and not undergoing the postoperative pulmonary rehabilitation program were factors associated with a higher risk of pneumonia. In multivariate analysis, age >80 years, history of stroke/cancer, thrombocytopenia, and hyperglycemia (>200 mg/dL) were identified as risk factors for pneumonia.The incidence of pneumonia was lower in the elderly patients with hip fractures who received the postoperative pulmonary rehabilitation program after surgery. This is the first trial to demonstrate the effect of a postoperative pulmonary rehabilitation program in hip surgery patients.
