From: An emergency department medical record review for adolescent intentional self-harm injuries

  Source: attending physician notes only Source: all notes available in the medical record
Provider-documented cases (N) Estimated PPV (%) 95% CI Provider-documented cases (N) Estimated PPV (%) 95% CI
Intentional self-harm 184 88.9(a) (83.8, 92.8) 189 91.3(b) (86.6, 94.8)
Intentional self-harm with intent to die (i.e. suicide attempt) 79 38.2 (31.5, 45.2) 95 45.9 (39.0, 52.9)
Suicidal ideation 106 51.2 (44.2, 58.2) 115 55.6 (48.5, 62.4)
  1. (a) Estimated PPV for the study definition to identify provider-documented ISH injuries using attending physician notes only for the specific encounter of care
  2. (b) Estimated PPV for the study definition to identify provider-documented ISH injuries using the documentation from attending physician and other providers/consults during the specific encounter of care
