2011 National Healthcare Quality and Disparities Reports

The National Healthcare Quality Report (NHQR) is a comprehensive national overview of quality of health care in the United States. It is organized around four dimensions of quality of care: effectiveness, patient safety, timeliness, and patient centeredness.

a. The Agency for Healthcare Research and Quality (AHRQ) Patient Safety Indicators (PSI) software requires that the sepsis be reported as a secondary diagnosis (rather than the principal diagnosis), but unlike the AHRQ PSI software, the secondary diagnosis could be present on admission. In addition, the sepsis is not verifiable as following surgery. Consistent with the AHRQ PSI software, the following cases are excluded: admissions with a principal diagnosis of infection, admissions with cancer or in an immunocompromised state, and obstetric admissions. Rates prior to 2008 are not reported because of International Classification of Diseases, 9th Revision coding changes.

b. Rates are adjusted by age, gender, age-gender interactions, comorbidities, major diagnostic category (MDC), diagnosis-related group (DRG), and transfers into the hospital. When reporting is by age, the adjustment is by gender, comorbidities, MDC, DRG, and transfers into the hospital; when reporting is by gender, the adjustment is by age, comorbidities, MDC, DRG, and transfers into the hospital. The AHRQ PSI software was modified to not use the present on admission (POA) indicators (or estimates of the likelihood of POA for secondary diagnosis).
