ABSTRACT
BACKGROUND: Patients often need admission at an Intensive Care Unit (ICU), immediately after complex abdominal wall reconstruction (CAWR). Lack of ICU resources requires adequate patient selection for a planned postoperative ICU admission. Risk stratification tools like Fischer score and Hernia Patient Wound (HPW) classification may improve patient selection. This study evaluates the decision-making process in a multidisciplinary team (MDT) on justified ICU admissions for patients after CAWR. METHODS: A pre-Covid-19 pandemic cohort of patients, discussed in a MDT and subsequently underwent CAWR between 2016 and 2019, was analyzed. A justified ICU admission was defined by any intervention within the first 24 h postoperatively, considered not suitable for a nursing ward. The Fischer score predicts postoperative respiratory failure by eight parameters and a high score (> 2) warrants ICU admission. The HPW classification ranks complexity of hernia (size), patient (comorbidities) and wound (infected surgical field) in four stages, with increasing risk for postoperative complications. Stages II-IV point to ICU admission. Accuracy of the MDT decision and (modifications of) risk-stratification tools on justified ICU admissions were analyzed by backward stepwise multivariate logistic regression analysis. RESULTS: Pre-operatively, the MDT decided a planned ICU admission in 38% of all 232 CAWR patients. Intra-operative events changed the MDT decision in 15% of all CAWR patients. MDT overestimated ICU need in 45% of ICU planned patients and underestimated in 10% of nursing ward planned patients. Ultimately, 42% went to the ICU and 27% of all 232 CAWR patients were justified ICU patients. MDT accuracy was higher than the Fischer score, HPW classification or any modification of these risk stratification tools. CONCLUSION: A MDT's decision for a planned ICU admission after complex abdominal wall reconstruction was more accurate than any of the other risk-stratifying tools. Fifteen percent of the patients experienced unexpected operative events that changed the MDT decision. This study demonstrated the added value of a MDT in the care pathway of patients with complex abdominal wall hernias.
