Vector Borne Diseases (VBDs) have a major impact on public health and socio-economic development. Inter-sectoral collaboration was recommended as one of the key elements of Integrated Vector Management (IVM), however limited evidence measures the effect and contribution of intersectoral approaches including but not only IVM. This systematic review aims to assess the existing evidence on all forms of inter-sectoral collaboration in VBD control and prevention, identify any gaps and develop a framework from a global perspective.
Articles were identified through a search of PUBMED, Science of Direct, Web of Knowledge, Google Scholar and WHO archives using key words and excluded duplications (n = 2,034). The exclusion of non-VBDs control and prevention interventions resulted in 194 eligible titles/abstract/keywords for full text assessment. Further exclusion of non-peer reviewed articles, non-declaration of ethical clearance, reviews and expert opinion articles resulted in 50 articles finally being included for analysis with the extraction of data on outcome, factor/s influencing the effectiveness, indicators of collaboration and sustainability.
Of the 50 articles included in the analysis, 19 articles were categorized as of moderate-strong quality. All articles compared pre- and post-intervention outcomes against disease or vector variables. Three papers included outcome variables on intersectoral collaboration and participation indicator. However, no paper undertook component analysis by different sectors or different activities. Only one paper compared cost data for community-intersectoral intervention for IRS and traditional “vertical” IRS. Six factors were identified as influencing the effectiveness of inter-sectoral collaboration. Five of six factors are the main ones, namely the approach (37/47), resources (34/47), relationships (33/47), management (29/47) and shared vision (20/47) factors. A conceptual framework has been developed based on this review.
This review shows the importance of inter-sectoral collaboration to reduce VBDs or vector densities. However, very few studies measured how much inter-sectoral collaboration contributes to the impact. Further high-quality studies using inter-sectoral collaboration indicators are recommended to be undertaken.
Based on existing knowledge, this atypical systematic review of ISC in VBDs control and prevention is the first review conducted on this topic. Several systematic reviews were undertaken to measure ISC but for different issues such as health equity and primary health care.
The recent global strategy of vector borne diseases control and prevention encourages inter-sectoral collaboration as an approach to achieve cost effective and efficient results from an intervention. This review shows inter-sectoral collaboration has played important role in achieving the impact on reduction of VBDs or vector densities. However, very few studies measured how much inter-sectoral collaboration contributed to the impact, nor for how long the ISC is needed to achieve sustainable IVM. It is recommended that further high-quality studies are undertaken using measures of indicators for inter-sectoral collaboration to address this critical gap. A conceptual framework and findings resulted in the review can be used as guideline to establish ISC on VBDs control and prevention. This work can help implementation of several recommended strategies in the Global Vector Control Response through providing an evidence base for implementers, providing some program logic to define outcomes of ISC and identifies a body of research to address gaps in robust evidence.
