Validation study reveals moderate diagnostic accuracy of administrative hospital records for stroke, suggesting cautious use for epidemiological surveillance.

Key Points

To evaluate the diagnostic validity of stroke reporting in the French Hospital Discharge Database compared with a population-based stroke registry as the reference standard.
Retrieved stroke records from 2004 to 2008 in the French Hospital Discharge Database (FHDDB) at Dijon Teaching Hospital.
Used the Dijon Stroke Registry as the gold standard to evaluate sensitivity, positive predictive value (PPV), and weighted kappa statistics.
The FHDDB demonstrated an overall sensitivity of 77.1% (95% CI, 74.2–80.0) and a PPV of 69.2% (95% CI, 66.1–72.2), identifying 625 true-positives, 278 false-positives, and 186 false-negatives out of 811 registry-confirmed cases.
Diagnostic agreement was moderate overall (weighted kappa = 52.8%; 95% CI, 46.8–58.9), but PPV was significantly higher for cardioembolic (86.7%) and lacunar strokes (84.6%; p < 0.0001).
PPV significantly improved over the study period (p < 0.0001), while sensitivity remained stable.
