  • The impact of investments in health systems

    Open AccessDeivis Nicolas Guzman-Tordecilla, Shivam Gupta et al.ARTICLEBMJ Global Health2026

    Investments in health systems are essential for achieving effective sustainable and equitable health outcomes. However, national and global level stakeholders continue to grapple with how to quantify the impact of investments, its return of investment, and how to efficiently allocate health system inputs to improve health service delivery, health outputs and outcomes. This rapid review highlights the diverse computational models used to simulate …

  • The effect of mobile phone messaging to support Covid-19 vaccination in Colombia

    Open AccessAndres I Vecino-Ortiz, Deivis Nicolas Guzman-Tordecilla et al.ARTICLEPLOS Global Public Health2026

    During the COVID-19 pandemic, the speed required and the complexity of the information provided about vaccines highlighted the relevance of communicating evidence effectively during a sanitary emergency. We tested three interactive voice response (IVR) interventions, plus one control to increase COVID-19 vaccine uptake in an adult population in Colombia. We conducted a parallel-group randomized controlled trial with four arms in Colombia between …

  • Bending the curve

    Open AccessAndres I Vecino-Ortiz, Timothy Roberton et al.ARTICLEPLOS Global Public Health2025

    Addressing the World Health Organization’s noncommunicable disease (NCD) “best buys” is key to reducing the disease burden in Latin America and the Caribbean (LAC). Yet, the potential impact of addressing NCD risk factors on current health expenditures (CHE) in LAC countries is unknown. This study uses both Global Burden of Disease (GBD) data and administrative information to model the impact of addressing four risk factors on CHE trends for 24 L…

  • Recruiting hard-to-reach populations via respondent driven sampling for mobile phone surveys in Colombia

    Open AccessCamila Solorzano-Barrera, Mariana Rodríguez-Patarroyo et al.ARTICLEGlobal Health Action2024

    BACKGROUND: Uptake of mobile phone surveys (MPS) is increasing in many low- and middle-income countries, particularly within the context of data collection on non-communicable diseases (NCDs) behavioural risk factors. One barrier to collecting representative data through MPS is capturing data from older participants.Respondent driven sampling (RDS) consists of chain-referral strategies where existing study subjects recruit follow-up participants …

  • Group-based trajectory models of integrated vaccine delivery and equity in low- and middle-income countries

    Open AccessSanjana Ravi, Sanjana J Ravi et al.ARTICLEInternational Journal for Equity…2024

    Integrated vaccine delivery is most strongly associated with improvements in vaccination equity in settings with high baseline levels of inequity. Continued scholarship is needed to further characterize the relationship between integration and health equity, as well as to improve measurement of vaccination coverage and integration

  • Developing digital tools for health surveys in low- and middle-income countries

    Open AccessGulam Muhammed Al Kibria, Saifuddin Ahmed et al.ARTICLEPLOS Global Public Health2023

    Non-communicable disease (NCD) risk factor data from low- and middle-income countries (LMICs) are inadequate, mostly due to the cost and burden of collecting in-person population-level estimates. High-income countries regularly use phone-based surveys, and with increasing mobile phone subscription in developing countries, mobile phone surveys (MPS) could complement in-person surveys in LMICs. We compared the representativeness and prevalence esti…

  • Improving Covid-19 vaccine uptake

    Open AccessNathaly Aya Pastrana, Sandra Milena Agudelo-Londoño et al.ARTICLEGlobal Health Action2023

    BACKGROUND: COVID-19 vaccination is a global priority. Latin American countries have some of the highest COVID-19 death rates worldwide with vaccination hampered by a variety of reasons, including mis- and disinformation, vaccine hesitancy, and vaccine supply constraints. Addressing vaccine hesitancy through effective messages has been found to help increase vaccine uptake. Participatory processes could be used to co-design health messages for th…

  • Evaluation of the implementation of the Framework Convention on Tobacco Control (FCTC) in Colombia

    Open AccessDeivis Nicolas Guzman-Tordecilla, Blanca Llorente et al.ARTICLEHealth Policy and Planning2022

    Evidence-based interventions recommended in the Framework Convention on Tobacco Control of the World Health Organization (WHO FCTC) are subject to implementation factors that might affect their actual effectiveness. The Colombian law enacting key commitments from WHO’s FCTC was signed in 2009. This study aims at evaluating the potential impact of the enactment and implementation of these WHO FCTC on four outcomes for tobacco consumption (last-yea…

  • Adaptation of a mobile phone health survey for risk factors for noncommunicable diseases in Colombia

    Open AccessAngelica Tórres Quintero, Ángela Vega et al.ARTICLEGlobal Health Action2020

    BACKGROUND: Data collection on noncommunicable disease (NCD) behavioral risk factors has traditionally been carried out through face-to-face surveys. However, its high costs and logistical difficulties can lead to lack of timely statistics for planning, particularly in low and middle-income countries. Mobile phone surveys (MPS) have the potential to fill these gaps. OBJECTIVE: This study explores perceptions, feasibility and strategies to increas…

  • Informed Consent for Mobile Phone Health Surveys in Colombia

    Open AccessMariana Rodríguez-Patarroyo, Angelica Tórres Quintero et al.ARTICLEJournal of Empirical Research on…2020Cited by: 2References: 2

    Public health surveys deployed through automated mobile phone calls raise a set of ethical challenges, including succinctly communicating information necessary to obtain respondent informed consent. This study aimed to capture the perspectives of key stakeholders, both experts and community members, on consent processes and preferences for participation in automated mobile phone surveys (MPS) of non-communicable disease risk factors in Colombia. …
