Cost-effectiveness of noninvasive ventilation for chronic obstructive pulmonary disease-related respiratory failure in Indian hospitals without ICU facilities

Abstract

Introduction:The majority of Indian hospitals do not provide intensive care unit (ICU) care or ward-based noninvasive positive pressure ventilation (NIV). Because no mechanical ventilation or NIV is available in these hospitals, the majority of patients suffering from respiratory failure die.Objective:To perform a cost-effective analysis of two strategies (ward-based NIV with concurrent standard treatment vs standard treatment alone) in chronic obstructive pulmonary disease (COPD) respiratory failure patients treated in Indian hospitals without ICU care.Materials and Methods:A decision-analytical model was created to compare the cost-effectiveness for the two strategies. Estimates from the literature were used for parameters in the model. Future costs were discounted at 3%. All costs were reported in USD (2012). One-way, two-way, and probabilistic sensitivity analysis were performed. The time horizon was lifetime and perspective was societal.Results:The NIV strategy resulted in 17.7% more survival and was slightly more costly (increased cost of $101 (USD 2012) but resulted in increased quality-adjusted life-years (QALYs) (1.67 QALY). The cost-effectiveness (2012 USD)/QALY in the standard and NIV groups was $78/QALY ($535.02/6.82) and $75/QALY ($636.33/8.49), respectively. Incremental cost-effectiveness ratio (ICER) was only $61 USD/QALY. This was substantially lower than the gross domestic product (GDP) per capita for India (1489 USD), suggesting the NIV strategy was very cost effective. Using a 5% discount rate resulted in only minimally different results. Probabilistic analysis suggests that NIV strategy was preferred 100% of the time when willingness to pay was >$250 2012 USD.Conclusion:Ward-based NIV treatment is cost-effective in India, and may increase survival of patients with COPD respiratory failure when ICU is not available.

Ward-Based Non-Invasive Ventilation in Acute Exacerbations of COPD: A Narrative Review of Current Practice and Outcomes in the UK

“…The authors of the YONIV trial report that the cost-savings were predominantly due to reduced utilisation of intensive care units. The cost benefits of ward-based NIV, versus admission to intensive care, are particularly important for low- and middle-income countries with limited access to critical care facilities [34]. Yeung et al [35] recently published a timely systematic review and Bayesian meta-analysis of randomised controlled trials that evaluated the use of NIV, compared to invasive ventilation, as a weaning strategy in adults mechanically ventilated for at least 24 h. The authors evaluated 25 studies comprising 1609 patients and found that NIV weaning was associated with a lower mortality rate at hospital discharge, shorter duration of invasive ventilation, lower rate of ventilator associated pneumonia, and a shorter length of stay in the intensive care unit.…”
