Effect of nurse-led, goal-directed lung physiotherapy on prognosis of patients with sepsis caused by Acinetobacter baumannii pulmonary infection

Abstract

Objectives: To investigate the role of nurse-led, goal-directed lung physiotherapy on the prognosis of patients with sepsis caused by Acinetobacter baumannii pulmonary infection. Methods: Patients with sepsis caused by A. baumannii pulmonary infection were recruited and divided into a control group (phase 1) and a treatment group (phase 2). Both groups received standard therapy for sepsis, and patients in phase 2 also received nurse-led, goal-directed lung physiotherapy. The primary outcome measure was 28-day mortality. Results: Among 742 patients with sepsis, 201 were diagnosed with A. baumannii pulmonary infection. Compared with patients in phase 1, patients in phase 2 had a significantly shorter duration of mechanical ventilation {median 4 (interquartile range (IQR) 3–5] vs 5 (IQR 3–12) days; P = 0.004}, lower intensive care unit (ICU) mortality [13.6% (18/132) vs 27.5% (19/69); P = 0.016] and lower 28-day mortality [21.2% (28/132) vs 37.7% (26/69); P = 0.012]. As a protective factor, nurse-led, goal-directed lung physiotherapy (odds ratio 0.341, 95% confidence interval 0.155–0.751; P = 0.008) was an independent risk factor for 28-day mortality. Conclusions: Nurse-led, goal-directed lung physiotherapy shortened the duration of mechanical ventilation and ICU stay, and decreased ICU mortality and 28-day mortality in patients with sepsis caused by A. baumannii pulmonary infection.
