Practice determinants for adherence to the Guide for the Comprehensive Clinical Care of Dengue Patients, Urabá (Colombia). A multifaceted approach to implementation research.

INTRODUCTION: Dengue is a significant public health issue in the Urabá region, accounting for 37.5% of morbidity and 41.7% of mortality resulting from dengue in the department of Antioquia (Colombia) in 2018. Clinical Practice Guidelines (CPGs) are tools based on Evidence-Based Medicine, intended for medical personnel to bridge the gap between proven intervention efficacy and clinical decision-making. This study aims to identify barriers and facilitators in the implementation of CPGs for dengue patient care by healthcare officials in the municipalities of the banana axis in the Urabá region. METHODOLOGY: From a multifaceted approach to implementation research, a mixed method study that combines qualitative and quantitative approaches, was conducted during the years 2020 and 2021, using combined instruments to identify determinants (Guide Indicative Factors, Individual factors of health professionals, Patient factors, Professional interactions, Incentives and resources, Capacity for organizational change, and lastly Social, political, and legal factors) affecting adherence to the Comprehensive Clinical Care Guide for Patients with Dengue (GACIPD). Semi-structured interviews and focus groups with healthcare workers were conducted to assess determinants based on clinical experience. Questionnaires on determinants of GACIPD adherence, using an adapted version of the Chronic Disease Implementation Checklist (TICD), were also employed. Qualitative analysis of the interviews and focus groups used a concept-based coding framework. The questionnaire responses were analyzed using Likert scaling and frequency counts of determinants within and across domains. Participants included general practitioners, other health professionals, researchers, academics, and administrators. RESULTS: There was a total of 103 participants in focus groups, 7 in semi-structured interviews, and 136 participants through questionnaires. Among the domains studied, the identification of barriers and facilitators emphasized institutional factors and individual factors. Organizational change capacity was identified as a major barrier, with only 3.6% of respondents indicating that their institution adjusted the prioritization of adequate care according to the guideline. The GACIPD domain received the highest facilitator rating, with 66.7% acceptance due to its practicality, simplicity, clarity, documentation, and ease of implementation, despite this, only 10% of professionals completely agree that their work is in accordance with the GACIPD. The determinant of patient factors was significant in the negative perception of adherence to GACIPD. CONCLUSIONS: Although barriers outweighed facilitators for GACIPD adherence, determinants for its use were generally positive, as most participants reported it as being a complete, documented, and easy-to-implement guide. The lack of knowledge of the guidelines impacting health professional's decision making was identified as a potentially modifiable barrier, and educational strategies could be implemented to overcome it. The region requires greater emphasis on the management of chronic health conditions, comorbidities, and coinfections of dengue with other endemic diseases.

Density of Aedes aegypti and dengue virus transmission risk in two municipalities of Northwestern Antioquia, Colombia.

The high infestation of Aedes aegypti populations in Urabá, Antioquia, Colombia represents a risk factor for increased dengue morbidity and mortality. This study aimed to determine the risk of dengue transmission by estimating the population of Ae. aegypti using entomological indices, density of females per dwelling and inhabitant, and virological surveillance in two municipalities in Colombia. A cross-sectional study was conducted with quarterly entomological surveys in three neighborhoods of Apartadó and Turbo between 2021 and 2022. Aedes indices and vector density per dwelling and per inhabitant were calculated. The Kernel method was used for spatial analysis, and correlations between climatic variables and mosquito density were examined. Virus detection and serotyping in mosquitoes was performed using single-step reverse transcription polymerase chain reaction. The housing, reservoir, and Breteau indices were 48.9%, 29.5%, and 70.2%, respectively. The mean density of Ae. aegypti was 1.47 females / dwelling and 0.51 females / inhabitant. The overall visual analysis showed several critical points in the neighborhoods studied. There was significant correlation of vector density and relative humidity and precipitation in the neighborhoods 29 de noviembre and 24 de diciembre. Additionally, serotypes DENV-1 and DENV-2 were found. The overall indices for dwellings, reservoirs, and Breteau were lower than those recorded in 2014 in Urabá. The vector density results in this study were similar to those reported in other studies conducted in Latin America, and vector infection was detected. The Aedes and density indices are complementary, emphasizing the importance of continuous surveillance of Ae. aegypti to inform appropriate control strategies and prevent future dengue outbreaks in these municipalities.
