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 physiologic and metabolic derangements 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 derangement is not verifiable as following surgery.� Obstetric admissions and admissions for ketoacidosis, hyperosmolarity, diabetic coma, acute renal failure, chronic renal failure, acute myocardial infarction, cardiac arrhythmia, cardiac arrest, shock, hemorrhage, or gastrointestinal hemorrhage are excluded.

b. Rates are adjusted by age, gender, age-gender interactions, comorbidities, major diagnostic category (MDC), and diagnosis-related group (DRG).� 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).

Key: SE: standard error.
