Pilot Implementation of the Postoperative Hypothermia Management Care Bundle

Inadvertent perioperative hypothermia (IPH) is a common complication in surgical patients, with incidence rates ranging between 50% and 90% in anaesthetised individuals. This study aims to pilot and evaluate the effectiveness of a Postoperative Hypothermia Management Care Bundle developed based on standardised, evidence-based practices. The study will be conducted using a mixed-methods design in two phases. In the first phase, the care bundle will be piloted over six months in the Cardiovascular Surgery Intensive Care Unit. In the second phase, the bundle's effectiveness will be assessed using both quantitative and qualitative data. The study population includes nurses working in the relevant intensive care unit who meet inclusion criteria and volunteer to participate. Data collection tools include: Nurse Descriptive Information Form Postoperative Hypothermia Management Care Bundle Checklist Care Bundle Compliance Assessment Form Semi-structured Nurse Interview Questionnaire (qualitative) Patient Postoperative Hypothermia Follow-up Form Quantitative data will be analysed using descriptive statistics. Compliance with the care bundle will be calculated as the ratio of patients who received all care bundle parameters to those who should have received them. A compliance rate below 95% will be considered unsuccessful. Qualitative data will be analysed using Colaizzi's seven-step phenomenological method.
