Effect of Self-Proning on Respiratory Functions,Pneumonia Severity,and Mortality Risk Among Patients Diagnosed With Community-Acquired Pneumonia: A Nursing-Based Quasi-Experimental Study

Abstract

Assessing and monitoring respiratory parameters, such as respiratory rate, oxygen saturation, and lung sounds, is crucial for the management and prognosis of pneumonia patients. Prone positioning has been shown to improve oxygenation in patients with respiratory disorders, including pneumonia, by reducing ventilation/perfusion mismatch. However, there is a lack of evidence supporting the benefits of self-proning in spontaneously breathing pneumonia patients. This study aims to evaluate the effect of self-proning on respiratory functions, pneumonia, and mortality risk among patients diagnosed with community-acquired pneumonia. The study used a pre- and post-test quasi-experimental design with a control group, adhering to the Transparent Reporting of Evaluations with Nonrandomized Designs guidelines. It was conducted in the Medical Respiratory Department inpatient wards at the Respiratory Diseases Hospital in Alexandria, Egypt. The study recruited 128 patients with community-acquired pneumonia, conveniently assigned to an intervention group (n = 64) and a control group (n = 64). Data were collected using socio-demographic and historical data sheets, respiratory parameters assessment sheets, the confusion uremia respiratory rate and blood pressure (CURB-65) severity of pneumonia score, and the Pneumonia Severity Index. Prone positioning significantly positively impacted respiratory parameters in the intervention group compared to the control group. Specifically, the intervention group exhibited improvements in respiratory rate, oxygen saturation, reduced need for supplemental oxygen, and cough (p < .05). Furthermore, the intervention group exhibited fewer changes in findings from chest inspection, palpation, and auscultation. In addition, the severity of pneumonia was reduced in the intervention group compared to the control group, as indicated by lower CURB-65 (p = .014) and pneumonia severity index scores (p = .005). The study demonstrated that self-proning interventions significantly improved respiratory functions and reduced the risk of death among participants with community-acquired pneumonia. These findings suggest that self-proning is a beneficial technique for managing respiratory distress, particularly in non-intubated patients, and can be an effective strategy to improve patient outcomes in clinical settings.
