RESUMEN
Postoperative pulmonary complications (PPCs) are associated with poor patient outcomes, increased costs and prolonged hospitalizations. Incentive spirometry (IS) reduces PPC incidence, but patient IS adherence is often suboptimal. Thus, the purpose of this study was to explore patients' beliefs about, and knowledge of PPCs and IS. We observed IS technique and conducted interviews guided by qualitative descriptive methodologies and the Health Belief Model. Verbatim transcripts of interviews were analyzed using inductive and deductive content analytic methods. Twenty postoperative spinal surgery patients at a single tertiary hospital were enrolled. Five categories related to PPC and IS beliefs and knowledge were identified: (1) social support, (2) preventing a PPC, (3) learning about PPCs, (4) reminders, and (5) lack of IS knowledge. Understanding why patients do not adhere to IS protocols is crucial for minimizing the risk of iatrogenic PPCs and developing strategies to improve adherence to IS.
