| 9) COPD | 2.6 (2.5–2.6) | 1139.7 | 0.1 (−0.3 to +0.5) | −16.3 |
| 10) Complication of device/implant/graft | 2.3 (2.2–2.4) | 1038.4 | 1.2 (0.8 to 1.5) | 319.6 |
The ten most prevalent discharge diagnoses aggregated over the entire study period are presented, using AHRQ CCS categories derived from discharge ICD-9 codes. Percent changes in prevalence were computed by comparing the mean prevalence of these diagnoses in 1996 and 1997, compared to the mean prevalence in 2009 and 2010. The change in prevalence was calculated by subtracting the actual number of discharges in 2009–10 from the expected number if 1996–97 rates had applied in 2010. All N’s are weighted. CHF = Congestive heart Failure, Acute CVA = Acute cerebrovascular accident, UTI = Urinary tract infection, COPD = Chronic obstructive pulmonary disease, N = number of discharged patients, PAC = Post-acute care.
