Abstract
Postintensive care syndrome (PICS) is a combination of short-, medium-and long-term morbidities that occur in patients discharged from the Intensive care unit (ICU). ICU professionals have a crucial role in managing and understanding the PICS. This study aimed to develop the PICS Knowledge Test (PICS-KT), which measures ICU professionals'awareness and knowledge levels regarding PICS, and to determine its validity and reliability. The databases were searched in detail, scientific research related to PICS was analyzed, and the draft scale was created accordingly. A total of 117 doctors and nurses who had been working in the ICU for at least 6 months were included in the study. For the validity and reliability analysis of the test, content validity ratio, item difficulty index, item discrimination index values and Cronbach α were examined. The Cronbach's α reliability coefficient for the 46-item PICS-KT is 0.93, indicating high reliability. Scores range from 0 to 46, with 32 or higher considered successful, suggesting adequate knowledge of PICS among ICU professionals. Scores of 14 or less indicate minimal knowledge. Those with scores between 14 and 32 possess some knowledge but need improvement. PICS-KT assesses knowledge in four main areas: general information, risk factors/causes, symptoms and findingsand interventions. ICU professionals show high awareness of interventions for preventing and treating PICS, as indicated by a high mean score in the interventions subdimension. The PICS-KT is crucial in assessing healthcare professionals'understanding of the various short-, medium-and long-term morbidities associated with PICS. The study ensures that the test is a robust and dependable instrument for evaluating ICU professionals'knowledge about PICS.
