Systematic Review: Association Between Physicians' Clinical Experience and Quality of Care and Patient Outcomes.
Synthesis in Journal of general internal medicine, 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
backgroundPhysicians with longer clinical experience may accumulate, or conversely exhibit obsolescence of, clinical knowledge and skills.
objectiveThis systematic review aims to summarize current evidence of the impact of physician experience on quality of care and patient outcomes.
methodsWe conducted a systematic review by searching EMBASE and MEDLINE databases from 2005 to 2025. Studies were included if they evaluated an association between physician experience-either length of practice or age-and quality of care and patient outcomes (i.e., knowledge, adherence to standard of care, and clinical outcome).
resultsWe included 69 studies. Overall, 32 (46%) of 69 studies showed that physicians' experience or age has a negative impact on the quality of care and patient outcomes, whereas 16 (23%) studies reported a positive impact of experience or age. The negative impact of physician experience was observed in the knowledge and adherence to the standard of care domains: 12 (52%) of 23 studies in the knowledge domain and 14 (61%) of 23 studies in the adherence domain showed a negative effect of experience or age. We found mixed findings for clinical outcomes; six (26%) of 23 studies reported negative and nine (39%) reported positive associations. These relationships were consistent when we limited the studies with low or moderate risk of bias as well as moderate or low certainty of evidence.
conclusionsThe older age and increased experience of physicians were associated with inferior knowledge and less adherence but not correlated with clinical outcomes.
