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 potential in hospital complications and adverse events following surgeries, procedures, and childbirthadverse 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.
