•We introduce Japanese chest physiotherapy and investigate it’s efficacy for patietnts with inhalation injury.•The chest physiotherapy may reduce the incidence of pneumonia in patients with inhalation injury.•Early intervention of the chest physiotherapy in patients with inhalation injury can be expected to maintain Activities Daily Living (ADL) level. The purpose of this study was to clarify the efficacy of chest physiotherapy (CPT) in patients with inhalation injury in the acute phase. This was a single-institution retrospective study of patients with inhalation injury admitted to the Chukyo Hospital Burn Center from April 2004 to March 2014 who required endotracheal intubation for respiratory care. The patients were divided into two groups: the CPT group and the conventional physical therapy group. We compared the two groups according to the incidence of pneumonia, length of ICU/hospital stay, and level of activities of daily living at discharge. To match subject backgrounds, we conducted a propensity score matching analysis, and using a Cox regression analysis, we evaluated the effect of CPT on the first pneumonia event. Of 271 patients admitted to the burn center, 139 patients were included. The incidence of pneumonia in the CPT group was significantly lower and these patients required fewer days until they could sit on the edge of the bed compared with the conventional physical therapy group. In a Cox regression model, the hazard ratio for the first incidence of pneumonia in the CPT group vs. the conventional therapy group was 0.27 (95% confidence interval: 0.13–0.54, P = 0.0002) after propensity score matching. CPT reduces the incidence of pneumonia and facilitates patient mobilization following inhalation injury.
