Patients after lung resection heading to the high-dependency unit: a cost-effectiveness study for managing lung cancer patients

Abstract

Abstract Background Recently, most thoracic surgery units allocate patients post lung resection to high-dependency units (HDU) rather than the old trend of intensive care units (ITU). The aim of the study is to assess the safety and efficacy of such a policy. We compared a single group of patients who underwent lobectomies who were admitted to ITU before March 2011 and patients whom their destination was to HDU after that date. Preoperative factors and postoperative outcomes were compared. Results A total of 408 patients were studied, 203 post-lobectomy patients were admitted routinely to ITU before March 2011, while 205 patients were admitted to HDU after that date. The mean postoperative length of stay in ITU was 1.2 days while in HDU was 1.1 days. In-hospital mortality for the ITU group was 2.5% (n = 5) while in the HDU group was 1.4% (n = 3) (p = 0.43). ITU readmission was observed in 6.5% (n = 13) in the ITU group and 4.3% (n = 9) in the HDU group (p = 0.31). Total complications were present in 39% in the ITU group and 33% in the HDU group (p = 0.16). The total estimated cost of one ITU day per patient is 850 GBP in comparison with 430 GBP for the HDU group (p = 0.007). The incremental cost-effectiveness ratio of the HDU stay per year was US $32.130/QALY. Conclusion The high-dependency unit is a safe destination for post-lobectomy patients. The same concept may apply to all thoracotomy patients. Hospitals could adopt such a policy which offers a better financial option without jeopardizing the level of patient care or outcome.
