Diagnostic delay as health system navigation: a mixed-methods study of childhood cancer in Burkina Faso.
Article in BMC cancer, 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
backgroundDiagnostic delay is a major contributor to childhood cancer mortality in low- and middle-income countries (LMICs). Existing studies identify determinants of delay but provide limited insight into how delays accumulate across care pathways. This study examined diagnostic delay among children with cancer in Burkina Faso using a health system navigation perspective and an explanatory mixed-methods design.
methodsWe conducted a sequential explanatory mixed-methods study at the two national paediatric oncology units in Ouagadougou, Burkina Faso. Quantitative analyses of children with a first cancer diagnosis (n = 30) examined associations between total diagnostic delay, number of provider encounters, and entry-point provider type, using minimal multivariable regression models. Analyses were exploratory and intended to identify associations rather than establish causal relationships. Qualitative interviews with caregivers (n = 20) explored diagnostic trajectories and mechanisms of delay accumulation. Findings were integrated through a health system navigation framework.
resultsThe median total diagnostic delay was 103.5 days (IQR 58-196), with referral delay representing the longest component. A greater number of provider encounters was associated with longer total diagnostic delay (β = 0.22, 95% CI 0.02-0.41; p = 0.03). Qualitative analyses identified two dominant mechanisms of delay accumulation: fragmented looping across multiple providers and system-induced diagnostic bottlenecks within higher-level biomedical facilities. Structural and social vulnerabilities further shaped families' ability to navigate referral pathways. Integrated analyses suggested that provider encounters reflected cumulative navigation complexity rather than simply repeated consultations.
conclusionsDiagnostic delay among children with cancer in Burkina Faso emerged as a cumulative process of health system navigation across a fragmented healthcare system. A health system navigation perspective may help inform strategies to reduce diagnostic delay by improving referral coordination, patient navigation, and diagnostic capacity in LMIC settings.
