Numerator

Table 2.10a: Non-neonatal medical and surgical discharges with any secondary diagnosis of iatrogenic pneumothorax (ICD-9-CM diagnosis code 512.1), excluding patients with trauma, thoracic surgery, lung or pleural biopsy, or cardiac surgery.

Comments

Table 2.10a: Rates are adjusted by age, gender, age-gender interactions, comorbidities, and Diagnosis Related Groups (DRG) clusters. When reporting is by age, the adjustment is by gender, comorbidities, and DRG clusters; when reporting is by gender, the adjustment is by age, comorbidities, and DRG clusters.

Table 2.10b: Rates are adjusted by age and gender using the total U.S. population for 2000 as the standard population. When reporting is by age, the adjustment is by gender only; when reporting is by gender, the adjustment is by age only.

Although not all States participate in the HCUP database, the Nationwide Inpatient Sample is weighted to give national estimates using weights based on all U.S. community, non-rehabilitation hospitals in the American Hospital Association Annual Survey of Hospitals.

These tables were created using version 2.1, revision 2, of the AHRQ PSI software. These measures are referred to as indicator 6 (discharge-based, table a) and 22 (area-based, table b) in the software documentation.
