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.

Assessment of a wearable fall prevention system at a veterans health administration hospital.

Objective: In-hospital falls are a significant cause of morbidity and mortality. The Veterans Health Administration (VHA) has designated fall prevention as a major focus area. The objective of this report is to assess the performance of a new sensor-enabled wearable system to prevent patient falls. Methods: An integrated sensor-enabled wearable SmartSock system was utilized to prevent falls at the acute care wards of a large VA hospital. Individual patients were only provided the SmartSocks when they were determined to be at high risk of falling. All fall count rates, with and without using the SmartSock, were evaluated and compared for individual patients. SmartSock sensor and electronic health record data were combined to assess the system's performance from February 10, 2021, through October 31, 2021. Results: There were 20.7 falls per 1000 ward days of care (WDOC) for those not using the SmartSocks compared to 9.2 falls per 1000 WDOC for patients using the SmartSocks. This represents a reduction of falls by more than half. These findings are further confirmed with a negative binomial regression model, which showed the use of the SmartSock had a statistically significant effect on the rate of falls (p = 0.03) when length of stay was held constant and demonstrated the odds of fall incident rate of 0.48 (95% CI, 0.24-0.92), that is less than half compared to when patients were not wearing the SmartSock. Conclusion: The use of a sensor-enabled wearable SmartSock fall prevention system resulted in a clinically meaningful and statistically significant decrease in falls in the acute care setting.
