Abstract TP409: Continuous Quality Improvement Implementation Across a Large Stroke Network of Affiliated Rural Hospitals

Background and Purpose: The stroke care network (SCN) currently includes 27 hospitals (one CSC, seven PSCs and four critical access facilities) and is responsible for nearly 7000 stroke discharges annually. Vital to our network’s mission is to improve care quality through a cooperative, evidence-based, standardized approach. Data submission began in February 2014 with 24 hospitals. The network compiled data results for a full year with a baseline purpose of analyzing submission and data trends. Methods: All affiliates receive standardized quality education upon joining the SCN. A data report form was used to collect and submit monthly stroke data elements quarterly. Door to CT Interpretation (OP-23), eight in-patient stroke core measures and the dysphagia performance measure were among many other quality metrics. Data was compiled for system analysis. Results: For calendar year 2014, 14 of 24 (58%) affiliate hospitals submitted data. The lowest scoring quality measures were STK-4: thrombolytic therapy (38%, N7), STK-8: stroke education (63%, N13) and (STK[PM]-7): dysphagia screening (59%, N6). Average time for CT interpretation was 46 minutes (range: 20-77 minutes). For stroke core measures, average was 73% for all appropriate measures (range: 38% (STK-4) - 88% (STK-2: discharged on antithrombotic)). Conclusions: Data submission is not yet uniform across the network, but areas to focus on quality have already emerged from the results—STK-4, STK-8, and (STK[PM]-7). In addition to program advisory services to improve submission compliance, the network proposal includes focused initiatives as a system, targeting tPA, patient education and dysphagia screening. Strengths of the continuous quality improvement initiative will include collaboration, sharing of best practices and a strong base in evidence.

Responses of Aboriginal and Torres Strait Islander Primary Health-Care Services to Continuous Quality Improvement Initiatives.

Indigenous primary health-care (PHC) services participating in continuous quality improvement (CQI) cycles show varying patterns of performance over time. Understanding this variation is essential to scaling up and sustaining quality improvement initiatives. The aim of this study is to examine trends in quality of care for services participating in the ABCD National Research Partnership and describe patterns of change over time and examine health service characteristics associated with positive and negative trends in quality of care. PHC services providing care for Indigenous people in urban, rural, and remote northern Australia that had completed at least three annual audits of service delivery for at least one aspect of care (n = 73). Longitudinal clinical audit data from use of four clinical audit tools (maternal health, child health, preventive health, Type 2 diabetes) between 2005 and 2013 were analyzed. Health center performance was classified into six patterns of change over time: consistent high improvement (positive), sustained high performance (positive), decline (negative), marked variability (negative), consistent low performance (negative), and no specific increase or decrease (neutral). Backwards stepwise multiple logistic regression analyses were used to examine the associations between health service characteristics and positive or negative trends in quality of care. Trends in quality of care varied widely between health services across the four audit tools. Regression analyses of health service characteristics revealed no consistent statistically significant associations of population size, remoteness, governance model, or accreditation status with positive or negative trends in quality of care. The variable trends in quality of care as reflected by CQI audit tools do not appear to be related to easily measurable health service characteristics. This points to the need for a deeper or more nuanced understanding of factors that moderate the effect of CQI on health service performance for the purpose of strengthening enablers and overcoming barriers to improvement.

Impact of lean six sigma process improvement methodology on cardiac catheterization laboratory efficiency.

Operational inefficiencies are ubiquitous in several healthcare processes. To improve the operational efficiency of our catheterization laboratory (Cath Lab), we implemented a lean six sigma process improvement initiative, starting in June 2010. We aimed to study the impact of lean six sigma implementation on improving the efficiency and the patient throughput in our Cath Lab. All elective and urgent cardiac catheterization procedures including diagnostic coronary angiography, percutaneous coronary interventions, structural interventions and peripheral interventions performed between June 2009 and December 2012 were included in the study. Performance metrics utilized for analysis included turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start and manual sheath-pulls inside the Cath Lab. After implementation of lean six sigma in the Cath Lab, we observed a significant improvement in turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start as well as sheath-pulls inside the Cath Lab. The percentage of cases with optimal turn-time increased from 43.6% in 2009 to 56.6% in 2012 (p-trend<0.001). Similarly, the percentage of cases with an aggregate on-time start increased from 41.7% in 2009 to 62.8% in 2012 (p-trend<0.001). In addition, the percentage of manual sheath-pulls performed in the Cath Lab decreased from 60.7% in 2009 to 22.7% in 2012 (p-trend<0.001). The current longitudinal study illustrates the impact of successful implementation of a well-known process improvement initiative, lean six sigma, on improving and sustaining efficiency of our Cath Lab operation. After the successful implementation of this continuous quality improvement initiative, there was a significant improvement in the selected performance metrics namely turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start as well as sheath-pulls inside the Cath Lab.

Leadership, safety climate, and continuous quality improvement

Successful amelioration of medical errors represents a significant problem in the health care industry. There is a need for greater understanding of the factors that lead to improved process quality and patient safety outcomes in hospitals. We present a research model that shows how transformational leadership, safety climate, and continuous quality improvement (CQI) initiatives are related to objective quality and patient safety outcome measures. The proposed framework is tested using structural equation modeling, based on data collected for 204 hospitals, and supplemented with objective outcome data from the Centers for Medicare and Medicaid Services. The results provide empirical evidence that a safety climate, which is connected to the chief executive officer's transformational leadership style, is related to CQI initiatives, which are linked to improved process quality. A unique finding of this study is that, although CQI initiatives are positively associated with improved process quality, they are also associated with higher hospital-acquired condition rates, a measure of patient safety. Likewise, safety climate is directly related to improved patient safety outcomes. The notion that patient safety climate and CQI initiatives are not interchangeable or universally beneficial is an important contribution to the literature. The results confirm the importance of using CQI to effectively enhance process quality in hospitals, and patient safety climate to improve patient safety outcomes. The overall pattern of findings suggests that simultaneous implementation of CQI initiatives and patient safety climate produces greater combined benefits.

Trends over 8years in quality of diabetes care: results of the AMD Annals continuous quality improvement initiative.

Quality of care monitoring is a key strategy for health policy. In Italy, the AMD Annals continuous monitoring and quality improvement initiative has been in place since 2006. Results after 8years are now available. Quality of diabetes care indicators during the years 2004-2011 were extracted from electronic medical records of 300 diabetes clinics. From 200,000 to 500,000 patients with type 2 diabetes were analyzed per year. Six process indicators, eight intermediate outcome indicators, seven indicators of treatment intensity/appropriateness, and a quality of care summary score (Q score) were evaluated. Previous studies documented that the risk of developing a new cardiovascular event was 80% higher in patients with a Q score <15 and 20% higher in those with a score between 15 and 25, as compared to those with a score >25. The proportion of patients with HbA1c ≤7%, LDL cholesterol <100mg/dl, and blood pressure ≥140/90mmHg increased by 4.8, 21.9, and 10.0%, respectively. Process and treatment intensity/appropriateness indicators consistently improved. The proportion of patients with a Q score <15 decreased from 13.5 to 6.5%, while those with a Q score >25 increased from 22.9 to 38.5%. AMD Annals document the progress in quality of diabetes care. Longitudinal improvements in Q score can translate into less cardiovascular events, with evident clinical and economic implications. AMD Annals represent a physician-led effort not requiring allocation of extra-economic resources, which is easy to implement and deeply rooted in routine clinical practice. They are a potential case model for other healthcare systems.

A technology-based quality innovation to identify undiagnosed hypertension among active primary care patients.

The goal of this study was to develop a technology-based strategy to identify patients with undiagnosed hypertension in 23 primary care practices and integrate this innovation into a continuous quality improvement initiative in a large, integrated health system. In phase 1, we reviewed electronic health records (EHRs) using algorithms designed to identify patients at risk for undiagnosed hypertension. We then invited each at-risk patient to complete an automated office blood pressure (AOBP) protocol. In phase 2, we instituted a quality improvement process that included regular physician feedback and office-based computer alerts to evaluate at-risk patients not screened in phase 1. Study patients were observed for 24 additional months to determine rates of diagnostic resolution. Of the 1,432 patients targeted for inclusion in the study, 475 completed the AOBP protocol during the 6 months of phase 1. Of the 1,033 at-risk patients who remained active during phase 2, 740 (72%) were classified by the end of the follow-up period: 361 had hypertension diagnosed, 290 had either white-coat hypertension, prehypertension, or elevated blood pressure diagnosed, and 89 had normal blood pressure. By the end of the follow-up period, 293 patients (28%) had not been classified and remained at risk for undiagnosed hypertension. Our technology-based innovation identified a large number of patients at risk for undiagnosed hypertension and successfully classified the majority, including many with hypertension. This innovation has been implemented as an ongoing quality improvement initiative in our medical group and continues to improve the accuracy of diagnosis of hypertension among primary care patients.

Continuous practice quality improvement initiative for communication of critical findings in neuroradiology.

The authors examined faculty's compliance with a hospital-approved neuroradiology critical findings (CFs) policy, which requires urgent verbal communication with the clinical team when 17 specific critical pathologies are identified. During June 2011 to July 2013, 50 random neuroradiology reports were sampled monthly for the presence of CFs and appropriate action. Faculty were provided ongoing feedback, and at the end of 2 years, the medical records for cases with noncommunicated CFs were reviewed to identify potential adverse outcomes. Of the 1200 reviewed reports, 195 (16.3%) had and 1005 (83.8%) did not have a CF. A total of 176 of 195 (90.3%) cases with CFs were communicated, and compliance increased from 77.4% to 85.6% (P = .027) since the monthly sampling was instituted; 1 of 19 (5.3%) noncommunicated CFs resulted in a potential adverse event. The ongoing monthly feedback resulted in improved faculty compliance with the CF policy. However, a small number of cases with CFs are still not being communicated.

First-Year Outcomes of Incident Peritoneal Dialysis Patients in the United States

Patterns of early outcomes in peritoneal dialysis (PD) are not well studied and dialysis providers need to establish a baseline of key outcomes for continuous quality improvement initiatives. Retrospective cohort study. Incident PD patients from Fresenius Medical Care, North America from January 1 through December 31,2009. Case-mix, comorbid illness, and baseline laboratory values. Death, hospitalization, peritonitis, and switch to hemodialysis (HD) within the first year on PD therapy. Event rates and outcome predictors. Of 1,677 incident PD patients, 1,313 started on PD therapy and 367 switched from HD therapy within the first 90 days. Normalized first-year event rates for mortality, switch to HD therapy, peritonitis, and hospitalization were 10, 27, 42, and 128 per 100 patient-years, respectively. 336 of 463 (72.6%) first peritonitis episodes and 637of 939 (67.8%) first hospitalizations occurred within the first 6 months of PD treatment. Black race, higher body mass index, non-Hispanic ethnicity, peripheral vascular disease, and low weekly Kt/V associated with peritonitis risk. Dialysis vintage, female sex, diabetes, congestive heart failure, peripheral vascular disease, and history of limb amputation along with lower laboratory values for albumin, hemoglobin, and phosphorus and weekly Kt/V associated with hospitalization. Switchers to HD therapy (n=350) used central venous catheters 81.4% of the time as initial access (still 78.3% at 90 days later) because of lack of permanent access. Residual confounding from unmeasured variables and exclusion of patients with a training day but who never started home PD therapy. Despite low first-year mortality, incident PD patients had high morbidity, particularly within the first 3-6 months. Increased focus to identify patients at greatest risk for peritonitis and hospitalization, as well as evaluation of care processes and implementation of preventive strategies, is required. Access planning for transition to HD therapy needs more attention, even during the first PD year.

Impact of Continuous Quality Improvement Initiatives on Clinical Outcomes in Peritoneal Dialysis

We evaluated the role of a quality improvement initiative in improving clinical outcomes in peritoneal dialysis (PD). In a retrospective analysis of 6 years of data from a hospital registry, the period between 1 July 2005 and 30 June 2008 (control group) provided baseline data from before implementation of systemic outcomes monitoring, and the period between 1 July 2008 and 30 June 2011 [continuous quality improvement (CQI) group] represented the time when a CQI program was in place. Peritonitis incidence, patient and technique survival, cardiovascular status, causes of death, and drop-out were compared between the groups. In the 370 patients of the CQI group and the 249 patients of the control group, the predominant underlying kidney diseases were chronic glomerulonephritis and diabetic nephropathy. After implementation of the CQI initiative, the peritonitis rate declined to 1 episode in 77.25 patient-months from 1 episode in 22.86 patient-months. Ultrasound parameters of cardiac structure were generally unchanged in the CQI group, but significant increases in cardiothoracic ratio and interventricular septal thickness were observed in the control group (both p < 0.05). Patient survival at 1, 2, and 3 years was significantly higher in the CQI group (97.3%, 96.3%, and 96.3% respectively) than in the control group (92.6%, 82.4%, and 67.3% respectively, p < 0.001). Implementation of the CQI initiative also appeared to significantly improve technique survival rates: 95.6%, 92.6%, and 92.6% in the CQI group compared with 89.6%, 79.2%, and 76.8% in the control group (p < 0.001) after 1, 2, and 3 years respectively. Integration of a CQI process into a PD program can significantly improve the quality of therapy and its outcomes.

Improving Appropriate Use of Echocardiography and Single-Photon Emission Computed Tomographic Myocardial Perfusion Imaging: A Continuous Quality Improvement Initiative

Appropriate use criteria for cardiovascular imaging have been published, but compliance in practice has been incomplete, with persistent high rates of inappropriate use. The aim of this study was to show the efficacy of a continuous quality improvement (CQI) initiative to favorably influence the appropriate use of outpatient transthoracic echocardiography and single-photon emission computed tomographic (SPECT) myocardial perfusion imaging (MPI) in a large cardiovascular practice. In this prospective study, a multiphase CQI initiative was implemented, and its impact on ordering patterns for outpatient transthoracic echocardiography and SPECT MPI was assessed. Between November and December 2010, a baseline analysis of the application of appropriate use criteria to indications for outpatient transthoracic echocardiographic studies (n = 203) and SPECT MPI studies (n = 205) was performed, with studies categorized as "appropriate," "inappropriate," "uncertain," or "unclassified." The CQI initiative was then begun, with (1) clinician education, including didactic lectures and case-based presentations with audience participation; (2) system changes in ordering processes, with redesigned image ordering forms; and (3) peer review and feedback. A follow-up analysis was then performed between June and August 2012, with categorization of indications for transthoracic echocardiographic studies (n = 206) and SPECT MPI studies (n = 206). At baseline, 73.9% of echocardiographic studies were categorized as appropriate, 16.7% as inappropriate, 5.9% as uncertain, and 3.4% as unclassified. Similarly, for SPECT MPI studies 71.7% were categorized as appropriate, 18.5% as inappropriate, 7.8% as uncertain, and 1.9% as unclassified. Separate analysis of the two most important categories, appropriate and inappropriate, demonstrated a significant improvement after the CQI initiative, with a 63% reduction in inappropriate echocardiographic studies (18.5% vs 6.9%, P = .0010) and a 46% reduction in inappropriate SPECT MPI studies (20.5% vs 11.1%, P = .010). This study demonstrates the effective and persistent positive impact of a CQI initiative to reduce inappropriate ordering of cardiovascular imaging.

Continuous Quality Improvement Initiative for Pressure Ulcer Prevention

Hospital-acquired pressure ulcers can extend a patient's length of stay, decrease health-related quality of life, and increase the risk of mortality and cost of patient care. Although risk assessment and pressure ulcer prevention efforts had been in place for many years, our facility continued to be more than national averages and we identified a need for extensive education and consistency throughout the organization in order to reduce hospital-acquired pressure ulcer occurrences. The continuous quality improvement initiative implemented by Huntsville Hospital created a clinical culture of pressure ulcer prevention, resulting in improved patient outcomes and cost savings.

Quality Improvement Initiatives in Neonatal Intensive Care Unit Networks: Achievements and Challenges

Neonatal intensive care unit networks that encompass regions, states, and even entire countries offer the perfect platform for implementing continuous quality improvement initiatives to advance the health care provided to vulnerable neonates. Through cycles of identification and implementation of best available evidence, benchmarking, and feedback of outcomes, combined with mutual collaborative learning through a network of providers, the performance of health care systems and neonatal outcomes can be improved. We use examples of successful neonatal networks from across North America to explore continuous quality improvement in the neonatal intensive care unit, including the rationale for the formation of neonatal networks, the role of networks in continuous quality improvement, quality improvement methods and outcomes, and barriers to and facilitators of quality improvement.

Impact of Multidisciplinary Team Training and High Fidelity Simulation in Critical Patient Scenarios

We have evaluated the recent literature regarding the use of high fidelity simulation and multidisciplinary team training to emphasize the fundamental concepts of leadership, teamwork, and communication during critical patient events. Evidence exists to support the creation of multidisciplinary training programs that utilize high fidelity simulation and focus on cardiocerebral resuscitation. We believe that multidisciplinary simulation training, when combined with a continuous quality improvement (CQI) initiative, can address inadequate and reduced trainee exposure to critical events and may lead to improved patient outcomes.

Community Care of North Carolina’s Approach to Asthma Management

Community Care of North Carolina (CCNC) takes a comprehensive approach to asthma management. Support from CCNC helps providers follow evidence-based practice guidelines; data guide continuous quality improvement initiatives and inform the care of individual patients and populations; and care managers work with high-risk patients.

Weekly Dose Reports: The Effects of a Continuous Quality Improvement Initiative on Coronary Computed Tomography Angiography Radiation Doses at a Tertiary Medical Center

Numerous protocols have been developed to reduce cardiac computed tomography angiography (cCTA) radiation dose while maintaining image quality. However, cCTA practice is highly dependent on physician and technologist experience and education. In this study, we sought to evaluate the incremental value of real-time feedback via weekly dose reports on a busy cCTA service. This time series analysis consisted of 450 consecutive patients whom underwent physician-supervised cCTA for clinically indicated native coronary evaluation between April 2011 and January 2013, with 150 patients before the initiation of weekly dose report (preintervention period: April-September 2011) and 150 patients after the initiation (postintervention period: September 2011-February 2012). To assess whether overall dose reductions were maintained over time, results were compared to a late control group consisting of 150 consecutive cCTA exams, which were performed after the study (September 2012-January 2013). Patient characteristics and effective radiation were recorded and compared. Total radiation dose was significantly lower in the postintervention period (3.4 mSv [1.7-5.7] and in the late control group (3.3 mSv [2.0-5.3] versus the preintervention period (4.1 mSv [2.1-6.6] (P = .005). The proportion of high-dose outliers was also decreased in the postintervention period and late control period (exams <10 mSv were 88.0% preintervention vs. 97.3% postintervention vs. 95.3% late control; exams <15 mSv were 98.0% preintervention vs. 100.0% postintervention vs. 98.7% late control; exams <20.0 mSv were 98.7% preintervention vs. 100.0% postintervention vs. 100.0% late control). Weekly dose report feedback of site radiation doses to patients undergoing physician-supervised cCTA resulted in significant overall dose reduction and reduction of high-dose outliers. Overall dose reductions were maintained beyond the initial study period.

Do competing demands of physical illness in type 2 diabetes influence depression screening, documentation and management in primary care: a cross-sectional analytic study in Aboriginal and Torres Strait Islander primary health care settings

BackgroundRelatively little is known about how depression amongst people with chronic illness is identified and managed in diverse primary health care settings. We evaluated the role of complex physical needs in influencing current practice of depression screening, documentation and antidepressant prescriptions during a 12-month period, among adults with Type 2 diabetes attending Aboriginal and Torres Strait Islander primary care health centres in Australia.MethodsWe analysed clinical audit data from 44 health centres participating in a continuous quality improvement initiative, using previously reported standard sampling and data extraction protocols. Eligible patients were those with Type 2 diabetes with health centre attendance within the past 12 months. We compared current practice in depression screening, documentation and antidepressant prescription between patients with different disease severity and co-morbidity. We used random effects multiple logistic regression models to adjust for potential confounders and for clustering by health centre.ResultsAmong the 1174 patients with diabetes included, median time since diagnosis was 7 years, 19% of patients had a co-existing diagnosis of Ischaemic Heart Disease and 1/3 had renal disease. Some 70% of patients had HbAc1>7.0%; 65% had cholesterol >4.0 mmol1-1 and 64% had blood pressure>130/80 mmHg. Documentation of screening for depression and of diagnosed depression were low overall (5% and 6% respectively) and lower for patients with renal disease (Adjusted odds ratio [AOR] 0.21; 95% confidence interval [CI] 0.14 to 0.31 and AOR 0.34; 95% CI 0.15 to 0.75), and for those with poorly controlled disease (HbA1c>7.00 (AOR 0.40; 95% CI 0.23 to 0.68 and AOR 0.51; 95% CI 0.30 to 84)). Screening for depression was lower for those on pharmaceutical treatment for glycaemic control compared to those not on such treatment. Antidepressant prescription was not associated with level of diabetes control or disease severity.ConclusionsBackground levels of depression screening and documentation were low overall and significantly lower for patients with greater disease severity. Strategies to improve depression care for vulnerable populations are urgently required. An important first step in the Australian Indigenous primary care context is to identify and address barriers to the use of current clinical guidelines for depression screening and care.
