Return on Investment of 10-Valent Pneumococcal Conjugate Vaccine in Ecuador From 2010 to 2030.

OBJECTIVES: Ecuador introduced the pneumococcal conjugate vaccine in 2010. A recent time series analysis has demonstrated the impact of 10-valent pneumococcal conjugate vaccine (PCV10) on hospitalized pneumococcal disease in children. We leveraged these estimates to calculate the return on investment (ROI) of PCV10 in Ecuador from 2010 to 2030 at the national and regional levels. METHODS: We used 2 approaches to estimate the economic benefits: (1) cost of illness, which includes treatment, transportation, and productivity loss averted, (2) and the value of statistical life, which reflects society's average willingness to pay to save one life. Costs of the immunization program include vaccine costs (doses, syringes, injection supplies) and immunization delivery costs (personnel, cold chain equipment and maintenance, transportation, distribution services, and other recurrent costs). We estimated the ROI by dividing the net benefits by costs. RESULTS: The ROI using the cost-of-illness approach was slightly negative in the introduction year. From 2011 to 2020, we estimated the ROI to be 0.45 (0.15-0.73). For the future decade, the ROI is estimated at 0.37 (-0.03 to 1.03). Using the value-of-statistical-life approach, the ROI was 1.46 (0.82-2.17) in the introduction year. In the first decade, the ROI was 1.01 (0.49-1.60); in the second decade, the ROI fell to 0.83 (0.23-1.78). CONCLUSIONS: The results of this study demonstrate the total economic benefits of PCV10 in Ecuador exceed immunization program costs after the introduction year. Estimates from this study will inform country policy makers and will contribute to efforts to mobilize resources for immunization.

Reducing unnecessary antibiotic prescription through implementation of a clinical guideline on self-limiting respiratory tract infections.

BACKGROUND: Clinical guidelines (CG) are used to reduce variability in practice when the scientific evidence is sparse or when multiple therapies are available. The development and implementation of evidence-based CG is intended to organize and provide the best available evidence to support clinical decision making in order to improve quality of care. Upper respiratory tract infections (URTI) are the leading cause of misuse of antibiotics and a CG may reduce the unnecessary antibiotic prescription. METHODS: The aim of this quasi-experimental, before-after study was to analyze the short- and long-term effects of the implementation of a CG to decrease the rate of antibiotic prescription in URTI cases in the emergency department of a third level private hospital in Quito, Ecuador. The study included 444 patients with a main diagnosis of URTI. They were distributed in three groups: a baseline cohort 2011 (n = 114), a first post-implementation cohort 2011 (n = 114), and a later post-implementation cohort 2018 (n = 216). The implementation strategy consisted of five key steps: acceptance of the need for implementation of the CG, dissemination of the CG, an educational campaign, constant feedback, and sustainability of the strategy through continuous training. RESULTS: The results of this study show a 42.90% of antibiotic prescription rate before the CG implementation. After the implementation of the CG, the prescription rate of antibiotics was significantly reduced by 24.5% (42.9% vs 18.4%, p<0.0001) and the appropriate antibiotic prescription rate was significantly increased by 44.2% (22.4% vs 66.6%, p<0.0001) in the first post-implementation cohort 2011. There was not a significant difference in antibiotic prescription rate and appropriate antibiotic prescription rate between two post-implementation cohorts: 18.4% vs 25.9% (p = 0.125) and 66.6% vs 50% (p = 0.191), respectively. CONCLUSIONS: The implementation of CGs decreases the rate of antibiotic prescription in URTI cases. The results are remarkable after early implementation, but the effect persists over time. The emphasis must shift from guideline development to strategy implementation.

[Health technology assessment in Ecuador's ministry of public health as a tool for drug purchasing from 2012 to 2015]. / La evaluación de tecnologías sanitarias en el Ministerio de Salud Pública de Ecuador como herramienta para la compra de medicamentos entre 2012 y 2015.

OBJECTIVE: Learn how the Ministry of Public Health (MSP, the Spanish acronym) of Ecuador uses health technology assessment (HTA) in decision-making on the purchase of drugs that are not on the National List of Essential Medicines (NLEM). METHODS: Information from databases of the Health Intelligence Directorate (DIS, the Spanish acronym) and the National Directorate of Drugs and Medical Devices (DNMDM, the Spanish acronym), was used to compare decisions made by both entities, to learn about the use and consistency of HTA reports in decisions on purchasing drugs not included in the NLEM. RESULTS: From 2012 to 2015, 227 reports were issued, of which 87 cover drugs; 36, devices; 29: medical procedures; 34: health programs; and 41: other medical technologies. The DNMDM requested 59 of the reports on drugs. There was 80% agreement in decisions made by the two directorates that participate in the process. CONCLUSIONS: The MSP, through the DIS, began using HTA in 2012. Given that the majority of reports evaluate drugs, it is essential that reports be prepared for other types of medical technologies and that they be prepared and used as widely as possible. Despite a high level of agreement in decisions, it is important to continue to improve the reports' scope and quality, and to monitor adoption and dissemination of authorized and funded technologies to learn the effectiveness and impact of HTA in Ecuador.

La evaluación de tecnologías sanitarias en el Ministerio de Salud Pública de Ecuador como herramienta para la compra de medicamentos entre 2012 y 2015 / Health technology assessment in Ecuador’s ministry of public health as a tool for drug purchasing from 2012 to 2015

Objetivo. Conocer el uso de la evaluación de tecnologías sanitarias (ETS) en la toma de decisiones del Ministerio de Salud Pública (MSP) del Ecuador para la compra de medicamentos que no se encuentran en el Cuadro Nacional de Medicamentos Básicos (CNMB). Métodos. Con la información de las bases de datos de la Dirección de Inteligencia de la Salud (DIS) y la Dirección Nacional de Medicamentos y Dispositivos Médicos (DNMDM), se compararon las decisiones tomadas por ambas instancias, para conocer el uso y la congruencia de los informes de ETS en las decisiones de compra de los medicamentos no incluidos en el CNMB. Resultados. Entre 2012 y 2015, se han elaborado 227 informes, de los cuales 87 corresponden a medicamentos, 36 a dispositivos, 29 a procedimientos médicos, 34 a programas sanitarios, y 41 a otras tecnologías médicas. De los informes de medicamentos, 59 fueron solicitados por la DNM. La concordancia entre las decisiones tomadas por las dos direcciones que participan en el proceso alcanzó 80%. Conclusiones. La ETS se inició en el MSP en 2012 a través de la DIS. Considerando que la mayoría de informes evalúan medicamentos, es indispensable que se desarrollen informes para otros tipos de tecnologías médicas y que se difunda al máximo su desarrollo y uso. A pesar de que el nivel de concordancia entre las decisiones es elevado, es importante seguir mejorando el alcance y la calidad de los informes, así como monitorizar la incorporación y difusión de las tecnologías autorizadas y financiadas para conocer la efectividad y el impacto de la ETS en Ecuador.

Cesarean section rates in Ecuador: a 13-year comparative analysis between public and private health systems / Tasas de cesárea en Ecuador: análisis comparativo de 13 años entre el sistema de salud público y el privado

Objective. To demonstrate the prevalence of cesearean sections (C-sections) in Ecuador and their distribution between private and public health centers. Methods. An observational population-based study was conducted of patients discharged from public and private hospitals in Ecuador after a C-section or vaginal delivery. Data were collected by the Ecuadorian National Institute of Statistics and Census (INEC) between 2001 and 2013. Results. The overall national C-section rate in the private health care system is double the rate in the public health care system. Over the 13 years of the study, C-sections accounted for 57.5% of births in the private sector, while the public sector proportion did not exceed 22.3%. Countrywide, less than 36% of C-sections were found to be clinically justified by parallel analysis of absolute or relative indications. Acute fetal distress (AFD) was more frequently reported in private centers compared to public ones (446 per 10 000 live births versus 274 per 10 000). Since 2001, the number of births by cesarean section increased by more than 50% (R² = 0.7306, P < 0.05), with an annual growth rate of 4.03%. In Guayaquil, the largest city in Ecuador, up to 74% of live births occurred by C-section. Conclusion. National data show that C-sections are performed more frequently in Ecuador than the rate recommended by the World Health Organization, especially in the private health care system. Private centers also report higher rates of AFD, which implies that this diagnosis is either overused in private centers or underrecognized in public centers. Although several factors might be influencing these trends, no data are available to determine the relative importance of economics, practicality, and medical or personal concerns of mothers and physicians in deciding which method of delivery should be used.

A nivel de todo el país, se observó que menos de 36% de las cesáreas estaban clínicamente justificadas con un análisis paralelo de indicaciones absolutas o relativas. Se notificaron casos de sufrimiento fetal agudo con mayor frecuencia en los centros privados comparados con los públicos (446 por 10 000 nacidos vivos frente a 274 por 10 000 n.v.). Desde el 2001, el número de nacimientos por cesárea aumentó más de 50% (R ² = 0,7306, P < 0,05), con una tasa de crecimiento anual de 4,03%. En Guayaquil, la ciudad más grande de Ecuador, hasta 74% de los nacidos vivos nacieron por cesárea. Conclusiones. Los datos nacionales muestran que las cesáreas se realizan en Ecuador con una frecuencia mayor a la tasa recomendada por la Organización Mundial de la Salud, especialmente en el sistema privado de atención de salud. Los centros privados también notifican tasas más altas de sufrimiento fetal agudo, lo que implica que este diagnóstico se utiliza excesivamente en los centros privados o no se lo reconoce suficientemente en los centros públicos. Aunque varios factores podrían estar influyendo sobre estas tendencias, no se tienen datos para determinar la importancia relativa de los factores económicos, la practicidad y las inquietudes médicas o personales de las madres y los médicos al decidir el método de parto.

Rabies Epidemiology and Control in Ecuador.

OBJECTIVE: Describe the epidemiology and the control effort for rabies in Ecuador. METHODS: This observational study included data from the Ecuadorian National Institute of Census and Statistics (INEC), and mortality and morbidity data reported by the Ministry of Public Health and the National Institute for Social Security. We conducted a phylogeny analyses to compare the N gene from the Challenge Virus Standard (CVS) vaccine strain used in Ecuador with published Cosmopolitan, Asian and Sylvatic strains. Descriptive and inferential statistics were used to determine the significance of the data. RESULTS: In 1996 Ecuador suffered the highest rate of rabies per capita in the Americas, with an incidence rate of 0.56 cases per 100 000 people per year. Human and canine rabies showed a sharp decline until 2012. Between 1994 and 2014, we found a correlation of 0.925 (p<0.01) between annual cases of dog and human rabies. In 2011, there was an epidemic of sylvatic rabies transmitted to people by vampire bats (Desmodus rotundus) in the Amazon region, specifically in Morona Santiago, leading to 11 fatalities. Phylogenetic analyses of the CVS vaccine N gene showed an association with urban canine rabies strains (the Cosmopolitan lineage and Asian strains), whereas sylvatic rabies, like those reported in the Amazon region, were found to be grouped in a different clade represented mainly by bat-derived strains. CONCLUSIONS: This study presents the first compilation of epidemiological data on rabies in Ecuador. The incidence of human and canine rabies, also known as urban rabies, has clearly decreased due to massive canine vaccination campaigns. Phylogenetic analysis of the prevailing vaccine used in the country showed a clear separation from bat-derived rabies, the source of recent rabies outbreaks. Efforts are ongoing to develop rabies vaccines that are highly specific to the rabies virus genotype circulating in the region, including sylvatic rabies. These efforts include the implementation of reverse genetics to generate recombinant virus coding for the prevailing glycoprotein gene.

A population-based study of the epidemiology of acute adult burns in Ecuador from 2005 to 2014.

OBJECTIVES: To describe the demographic, risk factor, occupational, and morbidity and mortality characteristics of burns in adults in Ecuador using national data. These data are from the only specialized public hospital in Ecuador that has a 12-bed burn unit. METHODS: The National Institute of Statistics and Census provided data from the burn unit of the Hospital Eugenio Espejo, in Quito. Three different datasets pertaining to burn deaths, burn unit inpatient admissions, and hospital discharge were analyzed. Patients who died or were discharged before entering the burn unit were not included in this analysis. RESULTS: During the 10-year period, 1106 patients were admitted to the burn unit, men represent 69.37% with 768 cases and women represent 30.62% with 337 patients; the number of patients per year was on average 123 cases; the average age was 33-34 years old, with a range between 16 and 96 years old. Heat (thermal) burns represent 65.78% followed by electrical with 30.53%, friction burns with 2.06%, and chemical burns with 1.62%. Domestic methane gas was the most frequent agent causing thermal burns and the most affected occupational groups are construction workers and people who stay at home. The overall mortality is 10.2% and the average length of stay was 23 days. CONCLUSIONS: Thermal burns are more frequent than any other cause of burns. Electrical burns are more frequent in Ecuador than anywhere else according to our research, meaning that control and prevention of workplace safety, urban planning, and home safety are scarce. The most affected groups are those dedicated to labor work. Finally, mortality in hospitalized patient is higher when compared with developed countries.

A unique case of facial burn superinfected with Dermatobia Hominis larvae resulting in a bilateral enucleation of the eyes.

We present a case of a female Ecuadorian patient who presented a deep facial burn injury complicated with a severe infestation of Dermatobia Hominis larvae. The burn injury was complicated by severe myiasis attributable to the poor management of the wound received at home, using tropical plants, which caused a secondary infection and severe necrosis of the tissue involving the forehead, cheeks, chin, scalp, nose, mouth and the eyes resulting in a bilateral enucleation and long inpatient hospital care.
