"Examining the Validity of AHRQ's Patient Safety Indicators (PSIs): Is Variation in PSI Composite Score Related to Hospital Organizational Factors?" Medical Care Research and Review 71 (6): 599-618.
Specifically, the new weights are based on three components: (i) excess harm associated with each individual PSI; (ii) the estimated preferences for health states reflected by these harms; and (iii) the volume of the PSI complication.
The figure suggests that for VISN-level data retention in the same third across years was more likely for the more frequent PSIs; in other words, VISNs were more likely to maintain their relative positions on these measures than on the less frequent PSIs.
The hospital-level data in Figure 3 show much different patterns, with less retention overall than for VISNs, though again average retention varied significantly across PSIs, F(12,311)= 23.43, p<.0001.
AHRQ has proposed multiple PSIs to broadly assess medical/surgical quality in inpatient settings.
We ran random-effects Tobit models for both risk-adjusted rates of PSIs and observed rates of PSIs.
The mean values of PSIs for CAHs and rural PPS hospitals are shown in Table 2.
In the pre- and postconversion comparisons, as shown on Table 3, after conversion to CAH status, hospitals experienced statistically significant improvement in performance as measured by PSI-7, PSI-15, and composite score of the four PSIs. There were no significant changes in hospital performance in PSI-2, PSI-3, PSI-5, and PSI-6.
