Description
Summary:This study aimed to assess the cost-effectiveness of a remotely operated referral management system (RORMS) compared with a conventional referral management system (CRMS) in Brazil. This is a model-based cost-effectiveness analysis under the perspective of the Unified Healthcare System (Sistema Único de Saúde [SUS]) in Brazil. A Markov microsimulation model was developed to compare costs and referral outcomes of the RORMS and the CRMS. Model consisted of 4 states representative of sequential stepwise assessments of referral suitability, 3 states representative of referral outcomes, and 1 exit model state. Target population represented cases being referred from primary healthcare units to specialized care in SUS. Model inputs related to costs and effectiveness in the RORMS arm were obtained from the data set of a RORMS between July and December 2019. Model inputs for the CRMS model arm were obtained from administrative data sets of 2 Brazilian localities for the year 2019. Relative effect size of RORMS in comparison with CRMS in SUS was obtained from published studies. Effectiveness outcome was unnecessary referrals averted. The incremental cost-effectiveness ratio was calculated for the base case. Probabilistic sensitivity analysis was conducted. In the base-case analyses, RORMS dominated CRMS, with expected cost-savings from $50.42 to $80.62 per unnecessary referral averted. RORMS was the dominant strategy in 83.7% of 100 000 simulations in the probabilistic sensitivity analysis. In 16.2% of simulations, incremental cost-effectiveness ratio was between $0 and $222 per unnecessary referral averted. Model-based simulations indicate that the RORMS is likely to be cost saving in comparison with the CRMS. •The effects of a series of telehealth strategies, such as e-consultation and telediagnosis, have been investigated in previous studies. The findings of these studies suggest that the use of telehealth is cost-effective in different settings compared with conventional healthcare.•We performed a model-based cost-effectiveness analysis of a remotely operated referral management system using telehealth strategies compared with the conventional referral system currently in place in the universal health system in Brazil. Base-case analysis resulted in cost-savings from $50.42 to $80.62 per unnecessary referral averted. Probabilistic sensitivity analysis suggested that the remotely operated referral management system is a dominant strategy or, in the worst scenario
