RESUMO
OBJECTIVES: As mobile phone ownership becomes more widespread in low-income and middle-income countries, mobile phone surveys (MPSs) present an opportunity to collect data on health more cost-effectively. However, selectivity and coverage biases in MPS are concerns, and there is limited information about the population-level representativeness of these surveys compared with household surveys. This study aims at comparing the sociodemographic characteristics of the respondents of an MPS on non-communicable disease risk factors to a household survey in Colombia. DESIGN: Cross-sectional study. We used a random digit dialling method to select the samples for calling mobile phone numbers. The survey was conducted using two modalities: computer-assisted telephone interviews (CATIs) and interactive voice response (IVR). The participants were assigned randomly to one of the survey modalities based on a targeted sampling quota stratified by age and sex. The Quality-of-Life Survey (ECV), a nationally representative survey conducted in the same year of the MPS, was used as a reference to compare the sample distributions by sociodemographic characteristics of the MPS data. Univariate and bivariate analyses were performed to evaluate the population representativeness between the ECV and the MPSs. SETTING: The study was conducted in Colombia in 2021. PARTICIPANTS: Population at least 18 years old with a mobile phone. RESULTS: We completed 1926 and 2983 interviews for CATI and IVR, respectively. We found that the MPS data have a similar (within 10% points) age-sex data distribution compared with the ECV dataset for some subpopulations, mainly for young populations, people with none/primary and secondary education levels, and people who live in urban and rural areas. CONCLUSIONS: This study shows that MPS could collect similar data to household surveys in terms of age, sex, high school education level and geographical area for some population categories. Strategies are needed to improve representativeness of the under-represented groups.

BACKGROUND: During the COVID-19 pandemic, Test-Trace-Isolate (TTI) programs have been recommended as a risk mitigation strategy. However, many governments have hesitated to implement them due to their costs. This study aims to estimate the cost-effectiveness of implementing a national TTI program to reduce the number of severe and fatal cases of COVID-19 in Colombia. METHODS: We developed a Markov simulation model of COVID-19 infection combined with a Susceptible-Infected-Recovered structure. We estimated the incremental cost-effectiveness of a comprehensive TTI strategy compared to no intervention over a one-year horizon, from both the health system and the societal perspective. Hospitalization and mortality rates were retrieved from Colombian surveillance data. We included program costs of TTI intervention, health services utilization, PCR diagnosis test, productivity loss, and government social program costs. We used the number of deaths and quality-adjusted life years (QALYs) as health outcomes. Sensitivity analyses were performed. FINDINGS: Compared with no intervention, the TTI strategy reduces COVID-19 mortality by 67%. In addition, the program saves an average of $1,045 and $850 per case when observed from the social and the health system perspective, respectively. These savings are equivalent to two times the current health expenditures in Colombia per year. INTERPRETATION: The TTI program is a highly cost-effective public health intervention to reduce the burden of COVID-19 in Colombia. TTI programs depend on their successful and speedy implementation. FUNDING: This study was supported by the Colombian Ministry of Health through award number PUJ-04519-20 received by EPQ AVO and SDS declined to receive any funding support for this study.

RESUMO
Comparar el nivel de implementación del Modelo de Vigilancia de la Morbilidad Materna Extrema (MVMME) y las principales barreras y facilitadores respecto de la implementación en dos grupos de instituciones prestadoras de servicios de salud (IPS) de Colombia.Materiales y métodos: estudio mixto, que emplea técnicas de información cuantitativa (instrumento semiestructurado) y cualitativa (entrevista a profundidad). Las IPS en las que se inició el modelo IPS piloto (IPSP) fueron comparadas con otro grupo de IPS que no participó en la inserción inicial del mismo, las que se denominarán IPS control (IPSC). Ambas fueron seleccionadas por conveniencia en conjunto con el Ministerio de Salud. El nivel de implementación se presenta como proporción por institución. La información se trianguló para complementar la información de los diferentes componentes de la implementación del MVMME.Resultados: hubo diferencias en la implementación según el grupo de IPS, en IPSP hubo mayor difusión de protocolos, detección, notificación, flujo de la información, análisis y toma de decisiones. En IPSC hubo más dificultades con la asignación de la causa principal, definir criterios de evitabilidad e identificar demoras. El volumen de profesionales, las horas promedio mes y los perfiles eran mayores en IPSP que en IPSC. El rango del nivel de implementación entre las IPSP varió entre el 73 y el 94 %; en el grupo de IPSC el rango estuvo entre 41 y 90 %. En las IPSP había mayor claridad sobre el papel del MVMME como herramienta para mejorar la calidad en la atención de las gestantes. En IPSC, si bien consideraban que el modelo ayudaba a mejorar la calidad, era interpretado como una sobrecarga de trabajo.Conclusiones: el mayor desarrollo en IPSP podría estar asociado a un mayor acompañamiento por parte del MS-UNFPA, y una mayor voluntad política e institucional para su implementación...
To compare the level of implementation of the Extreme Maternal Morbidity Surveillance Model (EMMSM). and the main barriers and facilitators to the implementation in two groups of Healthcare Service Providers (HSP) in Colombia.Materials and methods: Mixed study using quantitative (semi-structured tool) and qualitative (In-depth interview) information techniques. The healthcare service providers in which the pilot model was implemented (pHSP) were compared with another group of healthcare institutions that did not participate in the initial implementation, hereinafter called control HSP (cHSP). They were are all selected jointly with the Ministry of Health (MoH) based on convenience. The level of implementation is presented in terms of proportions for each healthcare institution. The information was crossed-referenced in order to supplement the data of the various components of the EMMSM implementation.Results: Differences in implementation were found for each IPS group. In the IPSP there was greater dissemination of the protocols, detection, notification, information flows and decision-making.In the IPSC group there were more difficulties in determining main causes, defining avoidability criteria, and identifying delays. The numbers of professional staff, mean monthly hours and profiles were higher among the IPSP when compared with the IPSC...

Se estimó la carga de enfermedad en el IMSS en el año 2000. Resultados: similitud con subregión AMRO A y Australia en primeros diagnósticos, AVISAS Totales y APMP; mayor semejanza en AVD con subregiones AMRO B y D; esperanzas de vida totales similares a subregión AMRO A; esperanzas de vida con discapacidad semejantes a subregiones AMRO B y D; en entidades federativas, a mayor desarrollo socioeconómico, mayor AVD y esperanzas de vidas con discapacidad y menor APMP. Conclusión: Los afiliados al IMSS acumulan una carga de morbilidad mayor a lo esperado y en entidades federativas se asocia directamente con el desarrollo socioeconómico. Se infiere que, en el 2000, los afiliados al IMSS experimentaban baja mortalidad con expansión de morbilidad.
The burden of disease was estimated in people affiliated to the Mexican Social Insurance Institute -IMSS- in 2000.Main results: Similarities with AMRO A subregion and Australia in first causes of burden, total DALY and years lost due to premature mortality; similarities withAMRO B and D subregions in disability live expectancy; highest socioeconomic development associated with highest magnitude of years lived with disability and disability live expectancyat federative entities level. Conclusion: An unexpective high burden of morbidity with disability was found in people affiliated to IMSS; in federative entities, the burden of morbidity is associatedwith socioeconomic level. These results permit to infer, ecologically, that this population is experimented low levels of mortality with an expansion of morbidity.
