Admin Data May Misclassify Hospital Complications

Administrative data may not correctly assess pressure ulcer rates, compare hospitals
TUESDAY, Oct. 15 (HealthDay News) -- Use of administrative data frequently misclassifies hospitals' rates of hospital-acquired pressure ulcers (HAPUs), compared to surveillance data, according to a study published in the Oct. 15 issue of the Annals of Internal Medicine.
Jennifer A. Meddings, M.D., from the University of Michigan in Ann Arbor, and colleagues retrospectively analyzed administrative and surveillance data (Collaborative Alliance for Nursing Outcomes) from 196 acute care hospitals with at least six months of information available. Calculations of hospital-specific HAPU rates were defined as the percentage of discharged adults (from administrative data) or examined adults (from surveillance data) with at least one stage II or greater HAPU (HAPU2+).
The researchers found that, based on administrative data, the mean hospital-specific HAPU2+ rate was 0.15 percent, compared to 2.0 percent when surveillance data were used. Use of the surveillance data set for the 49 hospitals with HAPU2+ rates in the highest (worst) quartile based on administrative data resulted in performance grades of "superior" for three of these hospitals, "above average" for 14, "average" for 15, and "below average" for 17.
"Hospital performance scores generated from HAPU2+ rates varied considerably according to whether administrative or surveillance data were used, suggesting that administrative data may not be appropriate for comparing hospitals," the authors write.
