Budget impact analysis of surfactant therapy for bronchiolitis in critically ill infants: the Colombian National Health System perspective

Critical care of severe bronchiolitis during shortage of ICU resources

Large seasonal outbreaks of bronchiolitis put pressure on healthcare systems and particularly on intensive care units (ICUs). ICU admission is necessary to provide respiratory support to the severest cases, otherwise bronchiolitis can result in substantial mortality. ICU resources are often insufficient and there is scant evidence to guide the ICU clinical management. Most available studies do not cover the ICU-admitted cases and do not consider the associated public health issues. We review this topic through a multidisciplinary approach from both the clinical and public health perspectives, with an analysis based on pathophysiology and cost-effectiveness. We suggest ways to optimise respiratory care, minimise ICU stay, "protect" ICU beds and, whenever possible, make them available for other critically ill children. We also provide guidance on how to prepare ICUs to work under stressful conditions due to outbreaks and to reduce the risk of nosocomial cross-contamination, particularly in ICUs caring for high-risk children.

Cost-Utility of Continuous Positive Airway Pressure for Respiratory Distress in Preterm Infants in a Middle-Income Country

OBJECTIVES

Despite the increased popularity of continuous positive airway pressure (CPAP) for preterm infants with respiratory distress, there is still uncertainty about whether the additional costs of this device justify the clinical benefits provided. This study aims to evaluate the cost-utility of CPAP in spontaneously breathing preterm infants with respiratory distress.

METHODS

Using a decision tree model, we estimated the cost and quality-adjusted life-years (QALYs) associated with CPAP and supplemental oxygen alone by headbox or low-flow nasal cannula (SO). The model was analyzed probabilistically, and a value of information analysis was conducted to inform the value of conducting further research to reduce current uncertainties in the evidence base. Cost-effectiveness was evaluated at a willingness-to-pay value of US$5180.

RESULTS

The mean incremental cost of CPAP versus SO was US$600. The mean incremental benefit of CPAP versus SO was 0.04 QALY. The expected incremental cost per QALY was estimated at US$13 172. The mean incremental net monetary benefit was US$-324 with a 95% credible interval of US$-536 to US$-201. The overall expected value of perfect information per person affected by the decision was estimated to be US$2346.

CONCLUSIONS

Compared with SO, the use of CPAP in spontaneously breathing preterm infants with respiratory distress is not cost-effective in Colombia. Evidence should continue to be generated with real-life effectiveness data and economic evaluations in other countries to confirm our findings.

Systematic review and cost-utility of high flow nasal cannula versus continuous positive airway pressure in children with acute severe or moderate bronchiolitis in Colombia

BACKGROUND

Nasal Continuous Positive Airway Pressure (CPAP) and High-Flow Nasal Cannula (HFNC) have emerged as alternatives to orotracheal intubation and conventional invasive ventilation in patients with moderate to severe bronchiolitis. This study aims to evaluate the evidence and the cost-utility of HFNC compared to CPAP in infants with moderate-severe bronchiolitis in Colombia.

METHODS

The search includes electronic databases such as Pubmed, ScienceDirect, and Embase. Through inclusion and exclusion criteria, screen randomized controlled trials. A decision tree model was used to estimate the cost-utility of CPAP compared with HFNC in infants with moderate-severe bronchiolitis. Sensitivity analysis of transition probabilities, utilities, and cost was carried out.

RESULTS

Incorporate five studies that meet the criteria. The risk of intubation rate in the patients with CPAP is lower than HFNC (relative risk 0.62; 95% confidence interval 0.46-0.84; I2  = 0%) The base-case analysis showed that compared with HFNC, CPAP was associated with lower costs and higher quality-adjusted life years (QALYs). The expected annual cost per patient with CPAP was US$17,574 and with HFNC was US$29,421. The QALYs per person estimated with CPAP were 0.92 and with HFNC was 0.91. This position of absolute dominance of CPAP (CPAP has lower costs and higher QALYs than HFNI) makes it unnecessary to estimate the incremental cost-utility ratio.

CONCLUSIONS

CPAP is cost-effective, over the HFNC, in infants with severe-moderate bronchiolitis in Colombia. Our study provides evidence that should be used by decision-makers to improve clinical practice guidelines and should be replicated to validate their results in other countries.

Fractional exhaled nitric oxide and eosinophil count in induced sputum to guide the management of children with asthma: a cost-utility analysis

Introduction

Previous evidence has shown that fractional exhaled nitric oxide (FeNO) and eosinophil count in induced sputum (EO) are cost-effective relative to standard of care in guiding the management of children with persistent asthma. There is some doubt as if there are differences between these two biomarkers in terms of costs and benefits. Clarifying this doubt would allow prioritization of the design of clinical practice guidelines. The study aimed to compare in terms of costs and benefits these biomarkers in patients with asthma between 4 and 18 years of age.

Methods

A Markov model was used to estimate the cost-utility of asthma management using FeNO and EO in patients between 4 and 18 years of age. Transition probabilities, cost and utilities were estimated from previously published local studies, while relative risks were obtained from the systematic review of published randomized clinical trials. The analysis was carried out from a societal perspective.

Results

The expected annual cost per patient with EO was US $1376 (CI 95% US $1376–US $1377) and for FeNO was US $1934 (CI 95% US $1333–US $1334), with a difference of US $42.3 between these strategies. The Quality-adjusted life years (QALYs) per person estimated with EO was 0.95 (CI 95% 0.951–0.952) and for FeNO was 0.94 (CI 95% 0.930–0.940), with a difference of 0.01 between these strategies. The NMB with EO was US $4902 (CI 95% 4900–4904) and for FeNO was US $4841 (CI 95% 4839–4843). The incremental cost-effectiveness ratio of EO was $3566 per QALY gained regarding FeNO.

Conclusion

Our study demonstrates that induced sputum-guided management is a strategy cost-effective over FeNO and standard asthma management in Colombia. This evidence should encourage the adoption of any of these techniques to objectively guide the management of children with asthma in routine clinical practice in low-resource settings.
