2009 National Healthcare Quality and Disparities Reports
a For California, "admission type" (emergent, urgent, elective) that is used to include only elective admissions was unavailable on all discharges; instead, an indicator for scheduled admissions was used to identify elective admissions. For other States that included information on "admission type" but had some records missing that information, an alternate algorithm based on "admission source" and nonemergency/nonurgent diagnosis-related groups was used to include only elective admissions.
b Rates are adjusted by age, gender, age-gender interactions, comorbidities, and diagnosis-related group clusters.
DNC - Data were not collected.
DSU - Data do not meet the criteria for statistical reliability, data quality, or confidentiality.
