Multicenter Implementation of a Treatment Bundle for Patients with Sepsis and Intermediate Lactate Values.

RATIONALE: Treatments for patients with sepsis with intermediate lactate values (≥2 and <4 mmol/L) are poorly defined. OBJECTIVES: To evaluate multicenter implementation of a treatment bundle (including timed intervals for antibiotics, repeat lactate testing, and intravenous fluids) for hemodynamically stable patients with sepsis and intermediate lactate values in the emergency department. METHODS: We evaluated patients in annual intervals before and after bundle implementation in March 2013. We evaluated bundle compliance and compared outcome measures across groups with multivariable logistic regression. Because of their perceived risk for iatrogenic fluid overload, we also evaluated patients with a history of heart failure and/or chronic kidney disease. MEASUREMENTS AND MAIN RESULTS: We identified 18,122 patients with sepsis and intermediate lactate values, including 36.1% treated after implementation. Full bundle compliance increased from 32.2% in 2011 to 44.9% after bundle implementation (P < 0.01). Hospital mortality was 8.8% in 2011, 9.3% in 2012, and 7.9% in 2013 (P = 0.02). Treatment after bundle implementation was associated with an adjusted hospital mortality odds ratio of 0.81 (95% confidence interval, 0.66-0.99; P = 0.04). Decreased hospital mortality was observed primarily in patients with a heart failure and/or kidney disease history (P < 0.01) compared with patients without this history (P > 0.40). This corresponded to notable changes in the volume of fluid resuscitation in patients with heart failure and/or kidney disease after implementation. CONCLUSIONS: Multicenter implementation of a treatment bundle for patients with sepsis and intermediate lactate values improved bundle compliance and was associated with decreased hospital mortality. These decreases were mediated by improved mortality and increased fluid administration among patients with a history of heart failure and/or chronic kidney disease.

Evaluation Following Staggered Implementation of the "Rethinking Critical Care" ICU Care Bundle in a Multicenter Community Setting.

OBJECTIVES: To evaluate process metrics and outcomes after implementation of the "Rethinking Critical Care" ICU care bundle in a community setting. DESIGN: Retrospective interrupted time-series analysis. SETTING: Three hospitals in the Kaiser Permanente Northern California integrated healthcare delivery system. PATIENTS: ICU patients admitted between January 1, 2009, and August 30, 2013. INTERVENTIONS: Implementation of the Rethinking Critical Care ICU care bundle which is designed to reduce potentially preventable complications by focusing on the management of delirium, sedation, mechanical ventilation, mobility, ambulation, and coordinated care. Rethinking Critical Care implementation occurred in a staggered fashion between October 2011 and November 2012. MEASUREMENTS AND MAIN RESULTS: We measured implementation metrics based on electronic medical record data and evaluated the impact of implementation on mortality with multivariable regression models for 24,886 first ICU episodes in 19,872 patients. After implementation, some process metrics (e.g., ventilation start and stop times) were achieved at high rates, whereas others (e.g., ambulation distance), available late in the study period, showed steep increases in compliance. Unadjusted mortality decreased from 12.3% to 10.9% (p < 0.01) before and after implementation, respectively. The adjusted odds ratio for hospital mortality after implementation was 0.85 (95% CI, 0.73-0.99) and for 30-day mortality was 0.88 (95% CI, 0.80-0.97) compared with before implementation. However, the mortality rate trends were not significantly different before and after Rethinking Critical Care implementation. The mean duration of mechanical ventilation and hospital stay also did not demonstrate incrementally greater declines after implementation. CONCLUSIONS: Rethinking Critical Care implementation was associated with changes in practice and a 12-15% reduction in the odds of short-term mortality. However, these findings may represent an evaluation of changes in practices and outcomes still in the midimplementation phase and cannot be directly attributed to the elements of bundle implementation.

Multifocal Clinical Performance Improvement Across 21 Hospitals.

Improving quality and safety across an entire healthcare system in multiple clinical areas within a short time frame is challenging. We describe our experience with improving inpatient quality and safety at Kaiser Permanente Northern California. The foundations of performance improvement are a "four-wheel drive" approach and a comprehensive driver diagram linking improvement goals to focal areas. By the end of 2011, substantial improvements occurred in hospital-acquired infections (central-line­associated bloodstream infections and Clostridium difficile infections); falls; hospital-acquired pressure ulcers; high-alert medication and surgical safety; sepsis care; critical care; and The Joint Commission core measures.

e-Measures: insight into the challenges and opportunities of automating publicly reported quality measures.

Using electronic health records (EHR) to automate publicly reported quality measures is receiving increasing attention and is one of the promises of EHR implementation. Kaiser Permanente has fully or partly automated six of 13 the joint commission measure sets. We describe our experience with automation and the resulting time savings: a reduction by approximately 50% of abstractor time required for one measure set alone (surgical care improvement project). However, our experience illustrates the gap between the current and desired states of automated public quality reporting, which has important implications for measure developers, accrediting entities, EHR vendors, public/private payers, and government.

Fluid volume, lactate values, and mortality in sepsis patients with intermediate lactate values.

RATIONALE: Patients with severe sepsis without shock or tissue hypoperfusion face substantial mortality; however, treatment guidelines are lacking. OBJECTIVES: To evaluate the association between intravenous fluid resuscitation, lactate clearance, and mortality in patients with "intermediate" lactate values of 2 mmol/L or greater and less than 4 mmol/L. MEASUREMENTS AND MAIN RESULTS: This was a retrospective study of 9,190 patients with sepsis with intermediate lactate values. Interval changes between index lactate values and those at 4, 8, and 12 hours were calculated with corresponding weight-based fluid volumes. Outcomes included lactate change and mortality. Repeat lactate tests were completed in 94.7% of patients within 12 hours. Hospital and 30-day mortality were 8.2 and 13.3%, respectively, for patients with lactate clearance; they were 18.7 and 24.7%, respectively, for those without lactate clearance. Each 10% increase in repeat lactate values was associated with a 9.4% (95% confidence interval [CI] = 7.8-11.1%) increase in the odds of hospital death. Within 4 hours, patients received 32 (± 18) ml/kg of fluid. Each 7.5 ml/kg increase was associated with a 1.3% (95% CI = 0.6-2.1%) decrease in repeat lactate. Across an unrestricted range, increased fluid was not associated with improved mortality. However, when limited to less than 45 ml/kg, additional fluid was associated with a trend toward improved survival (odds ratio = 0.92; 95% CI = 0.82-1.03) that was statistically significant among patients with highly concordant fluid records. CONCLUSIONS: Early fluid administration, below 45 ml/kg, was associated with modest improvements in lactate clearance and potential improvements in mortality. Further study is needed to define treatment strategies in this prevalent and morbid group of patients with sepsis.

Kaiser Permanente's performance improvement system, part 3: multisite improvements in care for patients with sepsis.

BACKGROUND: In 2008, Kaiser Permanente Northern California implemented an initiative to improve sepsis care. Early detection and expedited implementation of sepsis treatment bundles that include early goal-directed therapy (EGDT) for patients with severe sepsis were implemented. METHODS: In a top-down, bottom-up approach to performance improvement, teams at 21 medical centers independently decided how to implement treatment bundles, using a "playbook" developed by rapid cycle pilot testing at two sites and endorsed by a sepsis steering committee of regional and medical center clinical leaders. The playbook contained treatment algorithms, standardized order sets and flow charts, best practice alerts, and chart abstraction tools. Regional mentors and improvement advisers within the medical centers supported team-building and rapid implementation. Timely and actionable data allowed ongoing identification of improvement opportunities. A consistent approach to performance improvement propelled local rapid improvement cycles and joint problem solving across facilities. RESULTS: The number of sepsis diagnoses per 1,000 admissions increased from a baseline value of 35.7 in July 2009 to 119.4 in May 2011. The percent of admitted patients who have blood cultures drawn who also have a serum lactate level drawn increased from a baseline of 27% to 97% in May 2011. The percent of patients receiving EGDT who had a second and lower lactate level within six hours increased from 52% at baseline to 92% in May 2011. CONCLUSION: Twenty-one cross-functional frontline teams redesigned processes of care to provide regionally standardized, evidence-based treatment algorithms for sepsis, substantially increasing the identification and risk stratification of patients with suspected sepsis and the provision of a sepsis care bundle that included EGDT.

The impact of removing financial incentives from clinical quality indicators: longitudinal analysis of four Kaiser Permanente indicators.

OBJECTIVE: To evaluate the effect of financial incentives on four clinical quality indicators common to pay for performance plans in the United Kingdom and at Kaiser Permanente in California. DESIGN: Longitudinal analysis. SETTING: 35 medical facilities of Kaiser Permanente Northern California, 1997-2007. PARTICIPANTS: 2 523 659 adult members of Kaiser Permanente Northern California. Main outcomes measures Yearly assessment of patient level glycaemic control (HbA(1c) <8%), screening for diabetic retinopathy, control of hypertension (systolic blood pressure <140 mm Hg), and screening for cervical cancer. RESULTS: Incentives for two indicators-screening for diabetic retinopathy and for cervical cancer-were removed during the study period. During the five consecutive years when financial incentives were attached to screening for diabetic retinopathy (1999-2003), the rate rose from 84.9% to 88.1%. This was followed by four years without incentives when the rate fell year on year to 80.5%. During the two initial years when financial incentives were attached to cervical cancer screening (1999-2000), the screening rate rose slightly, from 77.4% to 78.0%. During the next five years when financial incentives were removed, screening rates fell year on year to 74.3%. Incentives were then reattached for two years (2006-7) and screening rates began to increase. Across the 35 facilities, the removal of incentives was associated with a decrease in performance of about 3% per year on average for screening for diabetic retinopathy and about 1.6% per year for cervical cancer screening. CONCLUSION: Policy makers and clinicians should be aware that removing facility directed financial incentives from clinical indicators may mean that performance levels decline.
