Abstract
Introduction
To accurately assess evidence from environmental and public health field trials, context and implementation details of the intervention must be weighed with trial results; yet these details are under and inconsistently reported for water, sanitation, and hygiene (WASH), limiting the external validity of the evidence.
Methods
To quantify the level of reporting of context and implementation in WASH evaluations, we conducted a scoping review of the 40 most cited evaluations of WASH interventions published in the last 10 years (2012–2022). We applied criteria derived from a review of existing reporting guidance from other sectors including healthcare and implementation science. We subsequently reviewed main articles, supplements, protocols, and other associated resources to assess thoroughness of context and implementation reporting.
Results
Of the final 25 reporting items we searched for, four—intervention name, approach, location, and temporality—were reported by all studies. Five items—theory, implementer qualifications, dose intensity, targeting, and measured fidelity—were not reported in over a third of reviewed articles. Only two studies (5%) reported all items in our checklist. Only 74% of items were found in the main article, while the rest were found in separate papers (7%) or not at all (19%).
Discussion
Inconsistent reporting of WASH implementation illustrates a major challenge in the sector. It is difficult to know what interventions are actually being evaluated and how to compare evaluation results. This inconsistent and incomplete implementation reporting limits the ability of programmers and policy makers to apply the available evidence to their contexts. Standardized reporting guidelines would improve the application of the evidence for WASH field evaluations.
期刊介绍:
The International Journal of Hygiene and Environmental Health serves as a multidisciplinary forum for original reports on exposure assessment and the reactions to and consequences of human exposure to the biological, chemical, and physical environment. Research reports, short communications, reviews, scientific comments, technical notes, and editorials will be peer-reviewed before acceptance for publication. Priority will be given to articles on epidemiological aspects of environmental toxicology, health risk assessments, susceptible (sub) populations, sanitation and clean water, human biomonitoring, environmental medicine, and public health aspects of exposure-related outcomes.
