ABSTRACT
Dengue is a public health problem in Colombia and in the municipality of Girardot, an area of high risk for dengue transmission. We present the results of an economic evaluation from the societal perspective and 1-year time horizon comparing the regular control program for dengue prevention versus an intervention that comprised an environmental management strategy by covering the most Aedes aegypti productive breeding sites with insecticide covers, community actions, and educational activities. The effectiveness of the intervention was measured as the reduction in probability of dengue infection obtained from a community trial. Resource use was estimated from clinical records that were validated by clinical experts; unit costs were taken from national tariffs. Patient costs were obtained from a household survey. We found that the intervention generated an additional cost of USD20.9 per household and an incremental effectiveness of 0.00173 (reduction in the probability of reported dengue cases). Overall, both alternatives generate similar effectiveness, but the new intervention was associated with increasing costs. We conclude the new intervention is a potentially cost-effective option in areas where high prevalence of dengue exists.
ABSTRACT
OBJECTIVES: Since 2011, there is a recommendation in Colombia to value health procedures: apply the tariffs of a 2001 manual used in a former public insurer with an adjustment factor of 35% (Instituto de Seguros Sociales [ISS] 2001). Nevertheless, the adjustment factor is not periodically updated, which limits the external validity of studies using these values and might also affect internal validity of studies, given that we are using possibly biased unit costs. This study aimed to compare unit values for health procedures using 2 sources: the ISS 2001 manual and individual records of service provision in Colombia (Registros Individuales de Prestación de Servicios de Salud [RIPS]), to evaluate the validity of the adjustment factor proposed in the Colombian reference case. METHODS: Unit values of health procedures reported in the Los Registros Individuales de Prestación de Servicios de Salud between 2013 and 2016 were compared with the value resulting from applying the assumption of ISS 2001 +35%. Rate variations were analyzed at the national level, by region and type of procedure. RESULTS: In the base case, the average rate variation at the national level was 142% with respect to the base value of the ISS manual; the value for nonsurgical procedures is 63% higher than the ISS 2001 rates, whereas for surgical procedures the difference is 299%. CONCLUSIONS: It is necessary to update the current recommendation in Colombia to estimate the unit cost of health procedures, to improve the external validity of economic evaluations and budget impact analysis in the country.

Background: Undiagnosed congenital heart disease in the prenatal stage can occur in approximately 5 to 15 out of 1000 live births; more than a quarter of these will have critical congenital heart disease (CCHD). Late postnatal diagnosis is associated with a worse prognosis during childhood, and there is evidence that a standardized measurement of oxygen saturation in the newborn by cutaneous oximetry is an optimal method for the detection of CCHD. We conducted a systematic review of the literature and meta-analysis comparing the operational characteristics of oximetry and physical examination for the detection of CCHD. Methods: A systematic review of the literature was conducted on the following databases including published studies between 2002 and 2017, with no language restrictions: Pubmed, Science Direct, Ovid, Scopus and EBSCO, with the following keywords: oximetry screening, critical congenital heart disease, newborn OR oximetry screening heart defects, congenital, specificity, sensitivity, physical examination. Results: A total of 419 articles were found, from which 69 were selected based on their titles and abstracts. After quality assessment, five articles were chosen for extraction of data according to inclusion criteria; data were analyzed on a sample of 404,735 newborns in the five included studies. The following values were found, corresponding to the operational characteristics of oximetry in combination with the physical examination: sensitivity: 0.92 (CI 95%, 0.87-0.95), specificity: 0.98 (CI 95%, 0.89-1.00), for physical examination alone sensitivity: 0.53 (CI 95%, 0.28-0.78) and specificity: 0.99 (CI 95%, 0.97-1.00). Conclusions: Evidence found in different articles suggests that pulse oximetry in addition to neonatal physical examination presents optimal operative characteristics that make it an adequate screening test for detection of CCHD in newborns, above all this is essential in low and middle-income settings where technology medical support is not entirely available.
