Negotiating the diagnostic uncertainty of contested illnesses: physician practices and paradigms.
Swoboda, Debra A · Health (London, England : 1997) · 2008 · DOI
Quick Summary
This study surveyed 800 U.S. doctors to understand how they diagnose ME/CFS and similar illnesses that lack clear lab tests or agreed-upon causes. Researchers found that many doctors do diagnose these conditions, even without complete scientific consensus, by using practical strategies like consulting expert resources, ordering specific tests, and considering how the body might be affected. The study shows that doctors can rationally diagnose ME/CFS by using thoughtful decision-making processes, and that patients may benefit from seeing doctors who use these careful diagnostic approaches.
Why It Matters
This research validates that ME/CFS can be rationally diagnosed despite the absence of a single definitive biomarker, which helps legitimize the condition in medical practice. For patients, the findings suggest that seeking physicians who use systematic diagnostic strategies—rather than dismissing the illness—can lead to better recognition and care. The study provides a framework for understanding how emerging illnesses gain clinical acceptance and how doctors can navigate diagnostic uncertainty.
Observed Findings
A substantial portion of surveyed physicians, including non-specialists, diagnose CFS, MCS, and GWS despite lack of scientific consensus on their etiology and pathogenesis.
Physicians managing these contested illnesses use specific strategies: consulting ancillary information sources, conducting analytically informed testing, and considering physiological explanations.
Physicians use these practices to fit contested illnesses into an explanatory system that makes them credible to themselves, patients, and the medical community.
Inferred Conclusions
Physicians employ rational decision-making processes to diagnose illnesses lacking conclusive pathogenic and etiological explanations, demonstrating bounded rationality in clinical practice.
Diagnosing physicians advance the legitimacy of controversial illnesses by constructing systematic means for their diagnosis.
Patients may benefit from working with physicians who employ these diagnostic strategies, as they help manage complexity and ambiguity in the diagnostic process.
Remaining Questions
Do the diagnostic strategies identified lead to more accurate identification of patients with ME/CFS, or do different physicians using these strategies identify different populations?
What proportion of physicians who do NOT diagnose ME/CFS reject it based on evidence, bias, or lack of awareness of diagnostic criteria?
What This Study Does Not Prove
This study does not establish that the diagnostic strategies physicians use are universally accurate or that they identify the same patients across different doctors. It is observational and does not prove that using these strategies causes better patient outcomes. The cross-sectional design cannot establish whether physician paradigms shape diagnostic practices or vice versa, and the results reflect reported practices rather than actual clinical behavior.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
