A multidisciplinary three-phase approach to improve the clinical utility of patient safety indicators

Patient Safety Indicators at an Academic Veterans Affairs Hospital: Addressing Dual Goals of Clinical Care and Validity

BACKGROUND

Hospital-acquired complications add to patient morbidity and mortality, costs, length of stay, and negative patient experience. Patient Safety Indicators (PSIs) are a validated and widely used metric to evaluate hospital administrative data on preventing these events. Although many studies have addressed PSI validity, few have aimed to reduce PSI through clinical care. The authors aimed to reduce PSI events by addressing both validity and clinical care.

METHODS

Frontline clinicians used a deep dive template to provide input on all PSI cases, which were then reviewed by a PSI task force to identify performance gaps. After analyzing the frequency of gaps and cost-vs.-impact of potential solutions, five interventions were implemented to address the three most common, highly weighted PSIs: pressure ulcers, postoperative venous thromboembolism (VTE), and postoperative sepsis. Clinical care interventions included increasing patient mobility by creating a specialized mobility technician position, skin care audits to prevent pressure ulcers, and increasing use of pharmacologic VTE prophylaxis. Administrative interventions addressed improving clinician-coding concordance for sepsis and increasing documentation of comorbidities.

RESULTS

After interventions, the number of PSI events for composite PSI, VTE, and sepsis decreased by 41.3% (p = 0.039), 85.2% (p = 0.0091), and 51.5% (p = 0.063), respectively, relative to the preintervention period. Pressure ulcers increased by 33.3% (p = 0.0091).

CONCLUSION

Hospital complications cause substantial burden to hospitals, patients, and caregivers. Addressing administrative and clinical factors with targeted interventions led to reduction in composite PSI. Further efforts are needed locally to reduce the pressure ulcer PSI.

A Pragmatic Method for Measuring Inpatient Complications and Complication-Specific Mortality

OBJECTIVES

The primary objective of this study was to develop hospital-level metrics of major complications associated with mortality that allows for the identification of opportunities for improvement. The secondary objective is to improve upon current metrics for failure to rescue (i.e., death from serious but treatable complications.).

METHODS

Agency for Healthcare Research and Quality metrics served as the basis for identifying specific complications related to major organ system morbidity associated with death. Complication-specific occurrence rates, observed mortality, and risk-adjusted mortality indices were calculated for the study institution and 182 peer organizations using component International Classification of Disease, Tenth Revision codes. Data were included for adults over a 4-year period, with exclusion of hospice patients and complications present on admission. Temporal visualizations of each metric were used to compare past and recent performance at the study hospital and in comparison to peers.

RESULTS

The complication-specific method showed statistically significant differences in the study hospital occurrence rates and associated mortality rates compared with peer institutions. The monthly control-chart presentation of these metrics provides assessment of hospital-level interventions to prevent complications and/or reduce failure to rescue deaths.

CONCLUSIONS

The method described supplements existing metrics of serious complications that occur during the course of acute hospitalization allowing for enhanced visualization of opportunities to improve care delivery systems. This method leverages existing measure components to minimize reporting burden. Monthly time-series data allow interventions to prevent and/or rescue patients to be rapidly assessed for impact.

Postoperative respiratory failure: An update on the validity of the Agency for Healthcare Research and Quality Patient Safety Indicator 11 in an era of clinical documentation improvement programs

BACKGROUND

Administrative data can be used to identify cases of postoperative respiratory failure (PRF). We aimed to determine if recent changes to the Agency for Healthcare Research and Quality Patient Safety Indicator 11 (PSI 11) and adoption of clinical documentation improvement programs have improved the validity of PSI 11. We also analyzed reasons why PSI 11 was falsely triggered.

STUDY DESIGN

Cross-sectional study of all eligible discharges using health record data from five academic medical centers between October 1, 2012 and September 30, 2015.

RESULTS

Of 437 flagged records, 434 (99.3%) were accurately coded and 414 (94.7%) represented true clinical PRF. None of the false positive records involved respiratory failure present on admission. Most (78.3%) false positive records required airway protection but did not have respiratory failure.

CONCLUSION

The validity of PSI 11 has improved with recent changes to the code criterion and adoption of clinical documentation improvement programs.
