Objectives:
To investigate the effect of a new nursing method combining Plan-Do-Check-Act (PDCA) circulation management and nursing on the prognosis of patients with severe pneumonia.
Methods:
The clinical records of 98 patients treated in the Second Affiliated Hospital of Xi'an Jiaotong University from January 2019 to January 2021 were retrospectively analyzed. Patients were divided into the control group (n=49) and the PDCA group (n=49), which were intervened by routine nursing and PDCA nursing based on routine nursing, respectively, by the same group of nursing staff.
Results:
After PDCA care, the nutritional status (body weight; total protein, TP; albumin, ALB) and immune function (immunoglobulin A, IgA; immunoglobulin G, IgG) in the PDCA group were significantly higher than those in the control group. Compared with routine nursing, PDCA care significantly increased the levels of PaO2 and oxygenation index, and reduced PaCO2, thus improving patients' ventilation function. The levels of interleukin-6 (IL-6), C-reactive protein (CRP) and procalcitonin (PCT) decreased more significantly in the PDCA group, thus better inhibiting the inflammatory response. The PDCA group also had fewer cases of invasive mechanical ventilation, shorter time of invasive ventilation, noninvasive ventilation, total oxygen therapy, and hospitalization, and better prognosis.
Conclusions:
PDCA care can effectively improve the nursing quality and patients' satisfaction, and better alleviate patients' poor psychological emotions, which is conducive to building a harmonious doctor-patient relationship.
