Abstract

Objective: To explore the effect of Plan-Do-Check-Act (PDCA) cycle nursing on the prognosis of children with mycoplasma pneumonia (MMP).

Methods: Clinical data of 112 children with MMP who were admitted to Hangzhou Ninth People's Hospital from September 2020 to December 2022 were retrospectively analyzed. The children were divided into a control group (56 cases, receiving routine care) and a PDCA group (56 cases, receiving PDCA care) according to nursing interventions. Blood gas analysis, pulmonary function, inflammation levels, clinical treatment, complications, and satisfaction were compared between the two group pre- and post-care.

Results: The results showed that the children in PDCA group experienced a more significant improvement in blood oxygen levels, evidenced by increased PaO2 and SaO2 levels and decreased PaCO2 levels, as well as enhanced lung function. Meanwhile, PDCA care was more effective in reducing interleukin-6, C-reactive protein, and tumor necrosis factor-alpha levels in children. In addition, children in the PDCA group recovered more quickly, with shorter times to temperature normalization, cough improvement, asthma resolution, lung rales disappearance, and hospital stay. Moreover, PDCA nursing effectively reduced the incidence of intrapulmonary and extrapulmonary complications, and improved care quality and patient satisfaction.

Conclusions: The PDCA cycle nursing model significantly improves the prognosis of children with MMP by promoting faster recovery, reducing adverse reactions, and enhancing overall nursing satisfaction. This approach fosters a more harmonious doctor-patient relationship, contributing to better patient outcomes and a more effective care environment.

Keywords: PDCA cycle of care; lung function; mycoplasma pneumonia; prognosis.
