Mapping the evidence on environmental health services in healthcare facilities in low- and middle-income countries: A systematic literature inventory of over 4,000 studies.
Synthesis in International journal of hygiene and environmental health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEnvironmental health services in healthcare facilities-including water, sanitation, hygiene, waste management, cleaning, and infection control-prevent disease and strengthen healthcare delivery. Yet environmental health services are inadequate in many low- and middle-income countries (LMICs). Despite the importance of monitoring and improving services, no comprehensive evidence map exists to describe knowledge and gaps for action. The study objective was to comprehensively catalog published literature on environmental health services in healthcare facilities in LMICs by service domain, study type, and relevance to policy and practice.
methodsWe conducted a systematic literature search in 2023 and updated it in 2025. After performing database searches, we used a machine learning process to prioritize studies for manual title-abstract screening. Through a title/abstract tagging process, we developed a literature inventory that categorized studies by topic, design, and relevance to policy and practice objectives.
resultsThe literature inventory included 4381 studies. Fifty-eight percent of the studies were baseline assessments of environmental health services, 36% involved formative research (e.g., qualitative methods), and 13% evaluated interventions or implementation strategies. Most studies (62%) examined hygiene at points of care, while 9% examined water and 6% sanitation. Twenty-seven percent of studies examined services during the COVID-19 pandemic.
conclusionsThere is little evidence for effective interventions and implementation strategies to improve and sustain environmental health services, especially for water and sanitation services. Formative research on under-studied services can help policymakers set investment priorities. Findings can inform the development of research agendas and practical guidelines for improving access to safe healthcare environments.
