RESUMO
BACKGROUND: Inability to achieve primary fascial closure after damage control laparotomy is a frequently encountered problem by acute care and trauma surgeons. This study aims to compare the cost-effectiveness of Wittmann patch-assisted closure to the planned ventral hernia closure. METHODS: A literature review was performed to determine the probabilities and outcomes for Wittmann patch-assisted primary closure and planned ventral hernia closure techniques. Average utility scores were obtained by a patient-administered survey for the following: rate of successful surgeries (uncomplicated abdominal wall closure), surgical site infection, wound dehiscence, abdominal hernia and enterocutaneous fistula. A visual analogue scale (VAS) was utilized to assess the survey responses and then converted to quality-adjusted life years (QALYs). Total cost for each strategy was calculated using Medicare billing codes. A decision tree was generated with rollback and incremental cost-utility ratio (ICUR) analyses. Sensitivity analyses were performed to account for uncertainty. RESULTS: Wittmann patch-assisted closure was associated with higher clinical effectiveness of 19.43 QALYs compared to planned ventral hernia repair (19.38), with a relative cost reduction of US$7777. Rollback analysis supported Wittmann patch-assisted closure as the more cost-effective strategy. The resulting negative ICUR of -156,679.77 favored Wittmann patch-assisted closure. Monte Carlo analysis demonstrated a confidence of 96.8% that Wittmann patch-assisted closure was cost-effective. CONCLUSIONS: This study demonstrates using the Wittmann patch-assisted closure strategy as a more cost-efficient management of the open abdomen compared to the planned ventral hernia approach.
RESUMO
Intensive care unit-acquired weakness (ICU-AW) is a serious complication in critically ill patients. Therefore, timely and accurate diagnosis and monitoring of ICU-AW are crucial for effectively preventing its associated morbidity and mortality. This article provides a comprehensive review of ICU-AW, focusing on the different methods used for its diagnosis and monitoring. Additionally, it highlights the role of bedside ultrasound in muscle assessment and early detection of ICU-AW. Furthermore, the article explores potential strategies for preventing ICU-AW. Healthcare providers who manage critically ill patients utilize diagnostic approaches such as physical exams, imaging, and assessment tools to identify ICU-AW. However, each method has its own limitations. The diagnosis of ICU-AW needs improvement due to the lack of a consensus on the appropriate approach for its detection. Nevertheless, bedside ultrasound has proven to be the most reliable and cost-effective tool for muscle assessment in the ICU. Combining the Sequential Organ Failure Assessment (SOFA) score, Acute Physiology and Chronic Health Evaluation (APACHE) II score assessment, and ultrasound can be a convenient approach for the early detection of ICU-AW. This approach can facilitate timely intervention and prevent catastrophic consequences. However, further studies are needed to strengthen the evidence.
