The following measures belong to the group that falls into AHRQ's Patient Safety Indicator category. The Patient Safety Indicators (PSIs) are a set of indicators providing information on adverse events that occurred that are potentially preventable with high quality care. The PSIs were developed after a comprehensive literature review, analysis of ICD-9-CM codes, review by a clinician panel, implementation of risk adjustment, and empirical analyses.

.

The PSIs can be used to help hospitals identify potential adverse events that might need further study; provide the opportunity to assess the incidence of adverse events and in hospital complications using administrative data found in the typical discharge record; include indicators for complications occurring in hospital that may represent patient safety events; and, indicators also have area level analogs designed to detect patient safety events on a regional level.

SQL to acquire these measures is as follows:

.

Acquiring data on All PSI

select a.measure_id, a.author_measure_id, a.name_friendly

from measures as a, measure_groups_measures as b

where a.measure_id = b.measure_id

and b.measure_group_id = 22

.

Acquiring data on Hospital Level PSI

select a.measure_id, a.author_measure_id, a.name_friendly

from measures as a, measure_groups_measures as b

where a.measure_id = b.measure_id

and b.measure_group_id = 30

.

Acquiring data on Area Level PSI

select a.measure_id, a.author_measure_id, a.name_friendly

from measures as a, measure_groups_measures as b

where a.measure_id = b.measure_id

and b.measure_group_id = 31

.

This includes observed, risk-adjusted, and observed to expected measures..

Statistical significance is calculated using a 95% confidence interval on a standard z-test for state-wide values and populated in the sig_var_state field of pellucid2.entity_values.

CMS (Centers for Medicare and Medicaid Services) briefly calculated select hospital-level PSIs. These calculations were based on the information they received from hospitals nationally. They have "CMS" in their author_measure_id field.
