Barriers and enablers in the implementation of a quality improvement program for acute coronary syndromes in hospitals: a qualitative analysis using the consolidated framework for implementation research

Background

Ischemic heart disease causes a high disease burden globally and numerous challenges in treatment, particularly in developing countries such as China. The National Chest Pain Centers Program (NCPCP) was launched in China as the first nationwide, hospital-based, comprehensive, continuous quality improvement (QI) program to improve early diagnosis and standardized treatment of acute coronary syndromes (ACS) and improve patients’ clinical outcomes. With implementation and scaling up of the NCPCP, we investigated barriers and enablers in the NCPCP implementation process and provided examples and ideas for overcoming such barriers.

Methods

We conducted a nationally representative survey in six cities in China. A total of 165 key informant interviewees, including directors and coordinators of chest pain centers (CPCs) in 90 hospitals, participated in semi-structured interviews. The interviews were transcribed verbatim, translated into English, and analyzed in NVivo 12.0. We used the Consolidated Framework for Implementation Research (CFIR) to guide the codes and themes.

Results

Barriers to NCPCP implementation mainly arose from nine CFIR constructs. Barriers included the complexity of the intervention (complexity), low flexibility of requirements (adaptability), a lack of recognition of chest pain in patients with ACS (patient needs and resources), relatively low government support (external policies and incentives), staff mobility in the emergency department and other related departments (structural characteristics), resistance from related departments (networks and communications), overwhelming tasks for CPC coordinators (compatibility), lack of available resources for regular CPC operations (available resources), and fidelity to and sustainability of intervention implementation (executing). Enablers of intervention implementation were inner motivation for change (intervention sources), evidence strength and quality of intervention, relatively low cost (cost), individual knowledge and beliefs regarding the intervention, pressure from other hospitals (peer pressure), incentives and rewards of the intervention, and involvement of hospital leaders (leadership engagement, engaging).

Conclusion

Simplifying the intervention to adapt routine tasks for medical staff and optimizing operational mechanisms between the prehospital emergency system and in-hospital treatment system with government support, as well as enhancing emergency awareness among patients with chest pain are critically important to NCPCP implementation. Clarifying and addressing these barriers is key to designing a sustainable QI program for acute cardiovascular diseases in China and similar contexts across developing countries worldwide.

Factors Associated With Medical Staff's Engagement and Perception of a Quality Improvement Program for Acute Coronary Syndromes in Hospitals: A Nationally Representative Mixed-Methods Study in China

Background Medical staff represent critical stakeholders in the process of implementing a quality improvement (QI) program. Few studies, however, have examined factors that influence medical staff engagement and perception regarding QI programs. Methods and Results We conducted a nationally representative survey of a QI program in 6 cities in China. Quantitative data were analyzed using multilevel mixed-effects linear regression models, and qualitative data were analyzed using the framework method. The engagement of medical staff was significantly related to knowledge scores regarding the specific content of chest pain center accreditation (β=0.42; 95% CI, 0.27-0.57). Higher scores for inner motivation (odds ratio [OR], 1.79; 95% CI, 1.18-2.72) and resource support (OR, 1.52; 95% CI, 1.02-2.24) and lower scores for implementation barriers (OR, 0.81; 95% CI, 0.67-0.98) were associated with improved treatment behaviors among medical staff. Resource support (OR, 4.52; 95% CI, 2.99-6.84) and lower complexity (OR, 0.81; 95% CI, 0.65-1.00) had positive effects on medical staff satisfaction, and respondents with improved treatment behaviors were more satisfied with the QI program. Similar findings were found for factors that influenced medical staff's assessment of QI program sustainability. The qualitative analysis further confirmed and supplemented the findings of quantitative analysis. Conclusions Clarifying and addressing factors associated with medical staff's engagement and perception of QI programs will allow further improvements in quality of care for patients with acute coronary syndrome. These findings may also be applicable to other QI programs in China and other low- and middle-income countries. Registration URL: https://www.chictr.org.cn/; Unique identifier: Chi-CTR2100043319.

Factors Associated With County-Level Variation in Premature Mortality Due to Noncommunicable Chronic Disease in the United States, 1999-2017

IMPORTANCE

Progress against premature death due to noncommunicable chronic disease (NCD) has stagnated. In the United States, county-level variation in NCD premature mortality has widened, which has impeded progress toward mortality reduction for the World Health Organization (WHO) 25 × 25 target.

OBJECTIVES

To estimate variations in county-level NCD premature mortality, to investigate factors associated with mortality, and to present the progress toward achieving the WHO 25 × 25 target by analyzing the trends in mortality.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study focused on NCD premature mortality and its factors from 3109 counties using US mortality data for cause of death from the Centers for Disease Control and Prevention WONDER databases and county-level characteristics data from multiple databases. Data were collected from January 1, 1999, through December 31, 2017, and analyzed from April 1 through October 28, 2019.

EXPOSURES

County-level factors, including demographic composition, socioeconomic features, health care environment, and population health status.

MAIN OUTCOMES AND MEASURES

Variations in county-level, age-adjusted NCD mortality in the US residents aged 25 to 64 years and associations between mortality and the 4 sets of county-level factors.

RESULTS

A total of 6 794 434 deaths due to NCD were recorded during the study period (50.58% women; 16.49% aged 65 years or older). Mortality decreased by 4.30 (95% CI, -4.54 to -4.08) deaths per 100 000 person-years annually from 1999 to 2010 (P < .001) and decreased annually at a rate of 0.90 (95% CI, -1.13 to -0.73) deaths per 100 000 person-years annually from 2010 to 2017 (P < .001). Mortality in the county with the highest mortality was 10.40 times as high as that in the county with the lowest mortality (615.40 vs 59.20 per 100 000 population) in 2017. Geographic inequality was decomposed by between-state and within-state differences, and within-state differences accounted for most inequality (57.10% in 2017). County-level factors were associated with 71.83% variation in NCD mortality. Association with intercounty mortality was 19.51% for demographic features, 23.34% for socioeconomic composition, 16.40% for health care environment, and 40.75% for health-status characteristics.

CONCLUSIONS AND RELEVANCE

Given the stagnated trend of decline and increasing variations in NCD premature mortality, these findings suggest that the WHO 25 × 25 target appears to be unattainable, which may be related to broad failure by United Nations members to follow through on commitments of reducing socioeconomic inequalities. The increasing inequalities in mortality are alarming and warrant expanded multisectoral efforts to ameliorate socioeconomic disparities.

Implementing a STEMI system of care in urban Bangalore: Rationale and Study Design for heart rescue India

Background

A system of care designed to measure and improve process measures such as symptom recognition, emergency response, and hospital care has the potential to reduce mortality and improve quality of life for patients with ST-elevation myocardial infarction (STEMI).

Objective

To document the methodology and rationale for the implementation and impact measurement of the Heart Rescue India project on STEMI morbidity and mortality in Bangalore, India.

Study Design

A hub and spoke STEMI system of care comprised of two interventional, hub hospitals and five spoke hospitals will build and deploy a dedicated emergency response and transport system covering a 10 Km. radius area of Bangalore, India. High risk patients will receive a dedicated emergency response number to call for symptoms of heart attack. A dedicated operations center will use geo-tracking strategies to optimize response times including first responder motor scooter transport, equipped with ECG machines to transmit ECG's for immediate interpretation and optimal triage. At the same time, a dedicated ambulance will be deployed for transport of appropriate STEMI patients to a hub hospital while non-STEMI patients will be transported to spoke hospitals. To enhance patient recognition and initiation of therapy, school children will be trained in basic CPR and signs and symptom of chest pain. Hub hospitals will refine their emergency department and cardiac catheterization laboratory protocols using continuous quality improvement techniques to minimize treatment delays. Prior to hospital discharge, secondary prevention measures will be initiated to enhance long-term patient outcomes.

The 2017 International Joint Working Group recommendations of the Indian College of Cardiology, the Academic College of Emergency Experts, and INDUSEM on the management of low-risk chest pain in emergency departments across India

There have been no published recommendations for the management of low-risk chest pain in emergency departments (EDs) across India. This is despite the fact that chest pain continues to be one of the most common presenting complaints in EDs. Risk stratification of patients utilizing an accelerated diagnostic protocol has been shown to decrease hospitalizations by approximately 40% with a low 30-day risk of major adverse cardiac events. The experts group of academic leaders from the Indian College of Cardiology and Academic College of Emergency Experts in India partnered with academic experts in emergency medicine and cardiology from leading institutions in the UK and USA collaborated to study the scientific evidence and make recommendations to guide emergency physicians working in EDs across India.

Impact of a Pilot Intervention to Increase Physician-Patient Communication About Stroke Risk in Indonesia

In Indonesia, where stroke is the leading cause of death, we designed and tested a brief intervention to increase physician-patient conversations about stroke prevention in community health centers. The pilot study used a quasi-experimental design involving repeated cross-sectional data collection over 15 weeks to compare pre- and during-intervention differences within four centers. We conducted exit interviews with 675 patients immediately following their medical appointments to assess whether physicians discussed stroke risks and provided recommendations to modify their risk behaviors. From pre-intervention to during intervention, patients reported more frequent physician recommendations to modify their stroke risk behaviors. We also conducted interviews with eight providers (physicians and nurses) after the intervention to get their feedback on its implementation. This study demonstrated that a brief intervention to motivate physician-patient conversations about stroke prevention may improve these conversations in community health centers. While interventions to reduce risk hold considerable promise for reducing stroke burden, barriers to physician-patient conversations identified through this study need to be addressed.

Quality Improvement in Acute Ischemic Stroke Care in Taiwan: The Breakthrough Collaborative in Stroke

In the management of acute ischemic stroke, guideline adherence is often suboptimal, particularly for intravenous thrombolysis or anticoagulation for atrial fibrillation. We sought to improve stroke care quality via a collaborative model, the Breakthrough Series (BTS)-Stroke activity, in a nationwide, multi-center activity in Taiwan. A BTS Collaborative, a short-term learning system for a large number of multidisciplinary teams from hospitals, was applied to enhance acute ischemic stroke care quality. Twenty-four hospitals participated in and submitted data for this stroke quality improvement campaign in 2010–2011. Totally, 14 stroke quality measures, adopted from the Get With The Guideline (GWTG)-Stroke program, were used to evaluate the performance and outcome of the ischemic stroke patients. Data for a one-year period from 24 hospitals with 13,181 acute ischemic stroke patients were analyzed. In 14 hospitals, most stroke quality measures improved significantly during the BTS-activity compared with a pre-BTS-Stroke activity period (2006–08). The rate of intravenous thrombolysis increased from 1.2% to 4.6%, door-to-needle time ≤60 minutes improved from 7.1% to 50.8%, symptomatic hemorrhage after intravenous thrombolysis decreased from 11.0% to 5.6%, and anticoagulation therapy for atrial fibrillation increased from 32.1% to 64.1%. The yearly composite measures of five stroke quality measures revealed significant improvements from 2006 to 2011 (75% to 86.3%, p<0.001). The quarterly composite measures also improved significantly during the BTS-Stroke activity. In conclusion, a BTS collaborative model is associated with improved guideline adherence for patients with acute ischemic stroke. GWTG-Stroke recommendations can be successfully applied in countries besides the United States.

Usability Testing and Adaptation of the Pediatric Cardiovascular Risk Reduction Clinical Decision Support Tool

BACKGROUND

Cardiovascular disease (CVD) is 1 of the leading causes of death, years of life lost, and disability-adjusted years of life lost worldwide. CVD prevention for children and teens is needed, as CVD risk factors and behaviors beginning in youth contribute to CVD development. In 2012, the National Heart, Lung, and Blood Institute released their "Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents" for clinicians, describing CVD risk factors they should address with patients at primary care preventative visits. However, uptake of new guidelines is slow. Clinical decision support (CDS) tools can improve guideline uptake. In this paper, we describe our process of testing and adapting a CDS tool to help clinicians evaluate patient risk, recommend behaviors to prevent development of risk, and complete complex calculations to determine appropriate interventions as recommended by the guidelines, using a user-centered design approach.

OBJECTIVE

The objective of the study was to assess the usability of a pediatric CVD risk factor tool by clinicians.

METHODS

The tool was tested using one-on-one in-person testing and a "think aloud" approach with 5 clinicians and by using the tool in clinical practice along with formal usability metrics with 14 pediatricians. Thematic analysis of the data from the in-person testing and clinical practice testing identified suggestions for change in 3 major areas: user experience, content refinement, and technical deployment. Descriptive statistical techniques were employed to summarize users' overall experience with the tool.

RESULTS

Data from testers showed that general reactions toward the CDS tool were positive. Clinical practice testers suggested revisions to make the application more user-friendly, especially for clinicians using the application on the iPhone, and called for refining recommendations to be more succinct and better tailored to the patient. Tester feedback was incorporated into the design when feasible, including streamlining data entry during clinical visits, reducing the volume of results displayed, and highlighting critical results.

CONCLUSIONS

This study found support for the usability of our pediatric CVD risk factor tool. Insights shared about this tool may be applicable for designing other mHealth applications and CDS tools. The usability of decision support tools in clinical practice depends critically on receiving (ie, through an accessible device) and adapting the tool to meet the needs of clinicians in the practice setting.

Adoption of cardiovascular risk reduction guidelines: a cluster-randomized trial

BACKGROUND AND OBJECTIVES

Cardiovascular disease (CVD) and underlying atherosclerosis begin in childhood and are related to CVD risk factors. This study evaluates tools and strategies to enhance adoption of new CVD risk reduction guidelines for children.

METHODS

Thirty-two practices, recruited and supported by 2 primary care research networks, were cluster randomized to a multifaceted controlled intervention. Practices were compared with guideline-based individual and composite measures for BMI, blood pressure (BP), and tobacco. Composite measures were constructed by summing the numerators and denominators of individual measures. Preintervention and postintervention measures were assessed by medical record review of children ages 3 to 11 years. Changes in measures (pre-post and intervention versus control) were compared.

RESULTS

The intervention group BP composite improved by 29.5%, increasing from 49.7% to 79.2%, compared with the control group (49.5% to 49.6%; P < .001). Intervention group BP interpretation improved by 61.1% (from 0.2% to 61.3%), compared with the control group (0.4% to 0.6%; P < .001). The assessment of tobacco exposure or use for 5- to 11-year-olds in the intervention group improved by 30.3% (from 3.4% to 49.1%) versus the control group (0.6% to 21.4%) (P = .042). No significant change was seen in the BMI or tobacco composites measures. The overall composite of 9 measures improved by 13.4% (from 48.2% to 69.8%) for the intervention group versus the control group (47.4% to 55.2%) (P = .01).

CONCLUSIONS

Significant improvement was demonstrated in the overall composite measure, the composite measure of BP, and tobacco assessment and advice for children aged 5 to 11 years.

Implementation of the NHLBI integrated guidelines for cardiovascular health and risk reduction in children and adolescents: rationale and study design for young hearts, strong starts, a cluster-randomized trial targeting body mass index, blood pressure, and tobacco

BACKGROUND

Cardiovascular disease (CVD) and the underlying atherosclerosis begin in childhood, and their presence and intensity are related to known cardiovascular disease risk factors. Attention to risk factor control in childhood has the potential to reduce subsequent risk of CVD.

OBJECTIVE

The Young Hearts Strong Starts Study was designed to test strategies facilitating adoption of the National, Heart, Lung and Blood Institute supported Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents. This study compares guideline-based quality measures for body mass index, blood pressure, and tobacco using two strategies: a multifaceted, practice-directed intervention versus standard dissemination.

STUDY DESIGN

Two primary care research networks recruited practices and provided support for the intervention and outcome evaluations. Individual practices were randomly assigned to the intervention or control groups using a cluster randomized design based on network affiliation, number of clinicians per practice, urban versus nonurban location, and practice type. The units of observation are individual children because measure adherence is abstracted from individual patient's medical records. The units of randomization are physician practices. This results in a multilevel design in which patients are nested within practices. The intervention practices received toolkits and supported guideline implementation including academic detailing, an ongoing e-learning group. This project is aligned with the American Board of Pediatrics Maintenance of Certification requirements including monthly physician self-abstraction, webinars, and other elements of the trial.

SIGNIFICANCE

This trial will provide an opportunity to demonstrate tools and strategies to enhance CV prevention in children by guideline-based interventions.

Abstract WP372: Quality Improvement in Acute Ischemic Stroke Care in Taiwan: the Breakthrough Collaborative in Stroke

Background and Purpose: Guideline adherence for acute ischemic stroke (AIS) management is often suboptimal, particularly in thrombolytic therapy and anticoagulants for atrial fibrillation. We sought to achieve quality improvement of AIS patients via a collaborative learning model, the Breakthrough Series (BTS)-Stroke, in a nationwide, multi-center activity in Taiwan.

Methods: A BTS Collaborative, a short-term learning system for a large number of multidisciplinary teams from hospitals, was applied to enhance AIS care quality. There were 24 teaching and community hospitals participating in and submitting data for this stroke quality improvement campaign from August 2010 to June 2011. The Get With The Guideline (GWTG)-Stroke measures were adopted to evaluate the performance and outcome of the AIS patients. The results of this study were compared to those of the previous Taiwan Stroke Registry (TSR, 22642 AIS patients from 39 hospitals, 2006-08).

Results: Data from 24 hospitals with 13181 AIS patients during a 1-year period were analyzed. The BTS-Stroke (2010-11) had better performance as compared to the TSR (2006-08): intravenous thrombolysis frequency for all AIS patients (4.1% vs 1.5%), symptomatic hemorrhage after intravenous thrombolysis (6.0% vs 8.2%), early antithrombotics (96.6% vs 94.1%), anticoagulation for atrial fibrillation (57.1% vs 28.3%), lipid lowering drugs for low-density lipoprotein >100 mg/dL (63.4% vs 38.7%), antithrombotics at discharge (94.0% vs 85.5%), and one-month mortality (3.5% vs 4.0%). Temporal improvement was noted in 7 of 14 performance measures when the fourth BTS-Stroke quarter compared with the first quarter: intravenous thrombolysis frequency for all AIS patients (4.1% vs 3.7%), symptomatic hemorrhage after intravenous thrombolysis (3.4% vs 5.5%), lipid lowering drugs for low-density lipoprotein >100 mg/dL (67.3% vs 60.5%), antithrombotics at discharge (95.5% vs 91.4%), dysphagia screening (81.9% vs 63.4%), early rehabilitation (71.7% vs 63.6%), stroke education before discharge (95.6% vs 83.4%).

Conclusions: A BTS collaborative learning and campaign model can improve the guideline adherence of stroke. The GWTG-Stroke can be successfully applied to other countries outside the United States.

System-related interventions to reduce diagnostic errors: a narrative review

BACKGROUND

Diagnostic errors (missed, delayed or wrong diagnosis) have recently gained attention and are associated with significant preventable morbidity and mortality. The authors reviewed the recent literature and identified interventions that address system-related factors that contribute directly to diagnostic errors.

METHODS

The authors conducted a comprehensive search using multiple search strategies. First, they performed a PubMed search to identify articles exclusively related to diagnostic error or delay published in English between 2000 and 2009. They then sought papers from references in the initial dataset, searches of additional databases, and subject matter experts. Articles were included if they formally evaluated an intervention to prevent or reduce diagnostic error; however, papers were also included if interventions were suggested and not tested to inform the state of the science on the subject. Interventions were characterised according to the step in the diagnostic process they targeted: patient-provider encounter; performance and interpretation of diagnostic tests; follow-up and tracking of diagnostic information; subspecialty and referral-related issues; and patient-specific care-seeking and adherence processes.

RESULTS

43 articles were identified for full review, of which six reported tested interventions and 37 contained suggestions for possible interventions. Empirical studies, although somewhat positive, were non-experimental or quasi-experimental and included a small number of clinicians or healthcare sites. Outcome measures in general were underdeveloped and varied markedly among studies, depending on the setting or step in the diagnostic process.

CONCLUSIONS

Despite a number of suggested interventions in the literature, few empirical studies in the past decade have tested interventions to reduce diagnostic errors. Advancing the science of diagnostic error prevention will require more robust study designs and rigorous definitions of diagnostic processes and outcomes to measure intervention effects.

Patient-level and hospital-level determinants of the quality of acute stroke care: a multilevel modeling approach

BACKGROUND AND PURPOSE

Quality of care may be influenced by patient and hospital factors. Our goal was to use multilevel modeling to identify patient-level and hospital-level determinants of the quality of acute stroke care in a stroke registry.

METHODS

During 2001 to 2002, data were collected for 4897 ischemic stroke and TIA admissions at 96 hospitals from 4 prototypes of the Paul Coverdell National Acute Stroke Registry. Duration of data collection varied between prototypes (range, 2-6 months). Compliance with 8 performance measures (recombinant tissue plasminogen activator treatment, antithrombotics < 24 hours, deep venous thrombosis prophylaxis, lipid testing, dysphagia screening, discharge antithrombotics, discharge anticoagulants, smoking cessation) was summarized in a composite opportunity score defined as the proportion of all needed care given. Multilevel linear regression analyses with hospital specified as a random effect were conducted.

RESULTS

The average hospital composite score was 0.627. Hospitals accounted for a significant amount of variability (intraclass correlation = 0.18). Bed size was the only significant hospital-level variable; the mean composite score was 11% lower in small hospitals (≤ 145 beds) compared with large hospitals (≥ 500 beds). Significant patient-level variables included age, race, ambulatory status documentation, and neurologist involvement. However, these factors explained < 2.0% of the variability in care at the patient level.

CONCLUSIONS

Multilevel modeling of registry data can help identify the relative importance of hospital-level and patient-level factors. Hospital-level factors accounted for 18% of total variation in the quality of care. Although the majority of variability in care occurred at the patient level, the model was able to explain only a small proportion.

Trends in the Use of Evidence-Based Treatments for Coronary Artery Disease Among Women and the Elderly

Background— Significant disparities have been reported in the application of evidence-based guidelines in the treatment of coronary artery disease (CAD) in women and the elderly. We hypothesized that participation in a quality-improvement program could improve care for all patients and thus narrow treatment gaps over time.

Methods and Results— Treatment of 237 225 patients hospitalized with CAD was evaluated in the Get With the Guidelines–CAD program from 2002 to 2007. Six quality measures were evaluated in eligible patients without contraindications: aspirin on admission and discharge, β-blockers use at discharge, angiotensin-converting enzyme inhibitor or angiotensin receptor antagonist use, lipid-lowering medication use, and tobacco cessation counseling along with other care metrics. Over time, composite adherence on these 6 measures increased from 86.5% to 97.4% (+10.9%) in men and 84.8% to 96.2% (+11.4%) in women. There was a slight difference in composite adherence by sex that remained significant over time ( P <0.0001), but this was confined to patients <75 years. Composite adherence in younger patients (<75 years) increased from 87.1% to 97.7% (+10.6%) and from 83.0% to 95.1% (+12.1%) in the elderly (≥75 years) over time.

Conclusions— Among hospitals participating in Get With the Guidelines–CAD, guideline adherence has improved substantially over time for both women and men and younger and older CAD patients, with only slight age and sex differences in some measures persisting.

CONCLUSIONS

Among hospitals participating in Get With the Guidelines-CAD, guideline adherence has improved substantially over time for both women and men and younger and older CAD patients, with only slight age and sex differences in some measures persisting.

Hospital performance recognition with the Get With The Guidelines Program and mortality for acute myocardial infarction and heart failure

BACKGROUND

Many hospitals enrolled in the American Heart Association's Get With The Guidelines (GWTG) Program achieve high levels of recommended care for heart failure, acute myocardial infarction (MI) and stroke. However, it is unclear if outcomes are better in those hospitals recognized by the GWTG program for their processes of care.

METHODS

We compared hospitals enrolled in GWTG and receiving achievement awards for high levels of recommended processes of care with other hospitals using data on risk-adjusted 30-day survival for heart failure and acute MI reported by the Center for Medicare and Medicaid Services.

RESULTS

Among the 3,909 hospitals with 30-day data reported by Center for Medicare and Medicaid Services 355 (9%) received GWTG achievement awards. Risk-adjusted mortality for hospitals receiving awards was lower for both heart failure (11.0% vs 11.2%, P = .0005) and acute MI (16.1% vs 16.5%, P < .0001) compared to those not receiving awards. After additional adjustment for hospital characteristics and noncardiac performance measures, the reduction in mortality remained significantly lower for GWTG award hospitals for acute myocardial infraction (-0.19%, 95% CI -0.33 to -0.05), but not for heart failure (-0.11%, 95% CI -0.25 to 0.02). Additional adjustment for cardiac processes of care reduced the benefit of award hospitals by 28% for heart failure mortality and 43% for acute MI mortality.

CONCLUSIONS

Hospitals receiving achievement awards from the GWTG program have modestly lower risk adjusted mortality for acute MI and to a lesser extent, heart failure, explained in part by better process of care.

Weekend hospital admission and discharge for heart failure: association with quality of care and clinical outcomes

BACKGROUND

Although hospital admissions during weekends have been associated with worse quality of care and worse outcomes in some but not all medical conditions, the impact of weekend versus weekday admission and discharge for heart failure (HF) has not been well studied. This study investigates the association of (1) weekend compared to weekday HF admissions and discharges with quality of care and (2) weekend versus weekday HF admissions with length of stay (LOS) and mortality in the hospital.

METHODS

Data were analyzed for 81,810 HF admissions at 241 sites participating in Get With the Guidelines (GWTG)-HF from January 2005 to September 2008. The cohort was stratified by weekend versus weekday admission and discharge. Generalized estimating equations adjusted for patient and hospital characteristics and clustering.

RESULTS

Mean age was 72 +/- 14 years; left ventricular ejection fraction (LVEF) was 39+/-17%. Inhospital mortality was 3.0% and median LOS 4 days. Weekend admission was associated with decreased odds of LVEF documentation. Weekend discharge was associated with decreased odds of LVEF documentation and completed discharge instructions. Weekend HF admission compared to weekday admission was associated with slightly higher risk-adjusted odds of longer inhospital LOS (1.03 [1.01-1.05] and increased inhospital mortality (1.13 [1.02-1.27]).

CONCLUSIONS

Among GWTG-HF hospitals, weekend admission and discharge for HF were associated with similar quality of care in many but not all measures. Risk-adjusted LOS was slightly longer and mortality moderately higher for weekend HF admissions.

Differential use of warfarin for secondary stroke prevention in patients with various types of atrial fibrillation

Anticoagulation therapy significantly reduces the incidence of thromboembolic events in patients with atrial fibrillation (AF), and warfarin therapy at discharge is a class I-indicated drug in patients with ischemic stroke with persistent or paroxysmal AF without contraindications. The aim was to determine whether participation in the Get With The Guidelines-Stroke (GWTG-S) quality improvement program would be associated with improved adherence to anticoagulation guidelines for patients with all types of AF. Adherence to warfarin treatment at hospital discharge was assessed in eligible patients with AF who presented with stroke or transient ischemic attack, based on type of AF. Of patients with stroke, 10.5% presented with some form of AF. When AF was documented using electrocardiography or telemetry (ECG) during the present admission, eligible patients were more likely to receive warfarin compared with patients for whom AF was reported using medical history only (78.8% vs 49.4%; p<0.0001). Improvement after GWTG-S participation in warfarin use was observed in patients with ECG-documented AF (73.8% at baseline vs 88.5% after the intervention; p<0.0001), but not patients using history only. Women and elderly patients were less likely to receive warfarin, and these gaps in treatment did not narrow during the quality improvement program for patients with ECG-documented AF and those with history only. In conclusion, anticoagulation for stroke prevention was underused in general for patients with AF, even in such high-risk groups as patients with stroke. GWTG-S was associated with improved adherence for patients with ECG-documented AF, but patients with a history of AF alone were largely untreated.

Lipid levels in patients hospitalized with coronary artery disease: an analysis of 136,905 hospitalizations in Get With The Guidelines

BACKGROUND

Lipid levels among contemporary patients hospitalized with coronary artery disease (CAD) have not been well studied. This study aimed to analyze admission lipid levels in a broad contemporary population of patients hospitalized with CAD.

METHODS

The Get With The Guidelines database was analyzed for CAD hospitalizations from 2000 to 2006 with documented lipid levels in the first 24 hours of admission. Patients were divided into low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride categories. Factors associated with LDL and HDL levels were assessed along with temporal trends.

RESULTS

Of 231,986 hospitalizations from 541 hospitals, admission lipid levels were documented in 136,905 (59.0%). Mean lipid levels were LDL 104.9 +/- 39.8, HDL 39.7 +/- 13.2, and triglyceride 161 +/- 128 mg/dL. Low-density lipoprotein cholesterol <70 mg/dL was observed in 17.6% and ideal levels (LDL <70 with HDL > or =60 mg/dL) in only 1.4%. High-density lipoprotein cholesterol was <40 mg/dL in 54.6% of patients. Before admission, only 28,944 (21.1%) patients were receiving lipid-lowering medications. Predictors for higher LDL included female gender, no diabetes, history of hyperlipidemia, no prior lipid-lowering medications, and presenting with acute coronary syndrome. Both LDL and HDL levels declined over time (P < .0001).

CONCLUSIONS

In a large cohort of patients hospitalized with CAD, almost half have admission LDL levels <100 mg/dL. More than half the patients have admission HDL levels <40 mg/dL, whereas <10% have HDL > or =60 mg/dL. These findings may provide further support for recent guideline revisions with even lower LDL goals and for developing effective treatments to raise HDL.

An organized approach to improvement in guideline adherence for acute myocardial infarction: results with the Get With The Guidelines quality improvement program

BACKGROUND

Evidence-based guidelines from the American Heart Association are voluntary, and adherence is highly variable across the country. Get With The Guidelines (GWTG) is a national quality improvement program sponsored and developed by the American Heart Association. The objective of this study was to evaluate whether participation in GWTG is associated with greater adherence to guidelines for coronary artery disease (CAD).

METHODS

Data on adherence to guidelines were obtained from Hospital Compare, grouping hospitals according to participation in the GWTG-CAD program on January 1, 2004: GWTG-CAD hospitals, n = 223; non-GWTG-CAD hospitals, n = 3407. The GWTG program uses a patient management tool, education, and benchmarked quality reports to improve guideline adherence. Adherence to 8 national measures, including the use of aspirin and beta-blockers early and at discharge and timeline reperfusion, was analyzed. A composite score was also calculated. Multivariable logistic regression was performed for comparing composite adherence rates between groups.

RESULTS

Adherence to the overall Hospital Compare composite measure was higher in GWTG-CAD hospitals than in non-GWTG-CAD hospitals (mean [SD], 89.7% [10.0%] vs 85.0 [15.0%]; absolute increase, 4.7%; P < .001). Adherence to the GWTG-CAD performance measures (PM) composite was also higher (89.5% [11.0%] vs 83.0% [18.0%]; P < .001). In multivariate analysis, GWTG-CAD participation was associated with a modest absolute increase in adherence to the PM composite by 2.52% (95% confidence interval [CI], 0.19%-4.85%). Larger acute myocardial infarction volume by quartile (absolute increase, 14.2%; 95% CI, 12.2%-16.3%), geographic location in the Northeast, and teaching hospital status (absolute increase, 2.87%; 95% CI, 0.43-5.32) were also associated with improved adherence to the PM composite. As a control, evaluation of unrelated quality measures for pneumonia, showed lower adherence among GWTG-CAD participating hospitals (74.8% [7.3%] vs 76.1% [9.7%]; P = .005).

CONCLUSION

Participation in GWTG-CAD was independently associated with improvements in guideline adherence beyond that associated with public reporting.

Quality of care and outcomes among patients with heart failure and chronic kidney disease: A Get With the Guidelines -- Heart Failure Program study

BACKGROUND

Both heart failure (HF) and chronic kidney disease (CKD) are highly prevalent conditions that often coexist; however, the quality of care received by hospitalized patients with both is not known.

METHODS

The Get With the Guidelines - HF registry and performance improvement program prospectively collects data on patients hospitalized with HF. Performance measures to improve treatment of patients with HF and inhospital mortality were examined by kidney function based on glomerular filtration rate (GFR) categorized as normal (GFR > or = 90), mild (60 < or = GFR < 90), moderate (30 < or = GFR < 60), severe (15 < or = GFR < 30), and kidney failure (GFR < 15 or dialysis).

RESULTS

Nearly two thirds of hospitalized patients with HF (15,560 patients from 137 hospitals) also had CKD: moderate CKD (43.9%), severe CKD (14.2%), and kidney failure (6.6%). Inpatient mortality was higher for patients with more severe renal dysfunction. Those with kidney failure were significantly less likely to receive nearly all guidelines-based therapies. In contrast, those with moderate or severe CKD often received similar care when compared with those with normal kidney function, except for lower use of angiotensin-converting enzyme inhibitors or receptor blockers (odds ratio 0.19 [0.13-0.28] and 0.47 [0.36-0.62], respectively) and lower proportions with blood pressure control (odds ratio 0.70 [0.58-0.85] and 0.52 [0.42-0.63], respectively).

CONCLUSIONS

In a large contemporary cohort of patients hospitalized with HF, we found that renal dysfunction was a highly prevalent comorbidity. Despite higher mortality rates, patients with increased severity of renal dysfunction were less likely to receive important guideline-recommended therapies. Further efforts are needed to improve the care of patients with HF and CKD.

Impact of Time of Presentation on the Care and Outcomes of Acute Myocardial Infarction

Background— Prior studies have demonstrated an inconsistent association between patients’ arrival time for acute myocardial infarction (AMI) and their subsequent medical care and outcomes.

Methods and Results— Using a contemporary national clinical registry, we examined differences in medical care and in-hospital mortality among AMI patients admitted during regular hours (weekdays 7 am to 7 pm ) versus off-hours (weekends, holidays, and 7 pm to 7 am weeknights). The study cohort included 62 814 AMI patients from the Get With the Guidelines–Coronary Artery Disease database admitted to 379 hospitals throughout the United States from July 2000 through September 2005. Overall, 33 982 (54.1%) patients arrived during off-hours. Compared with those arriving during regular hours, eligible off-hour patients were slightly less likely to receive primary percutaneous coronary intervention (adjusted odds ratio [OR], 0.93; 95% confidence interval [CI], 0.89 to 0.98), had longer door-to-balloon times (median, 110 versus 85 minutes; P <0.0001), and were less likely to achieve door-to-balloon ≤90 minutes (adjusted OR, 0.34; 95% CI, 0.29 to 0.39). Arrival during off-hours was associated with slightly lower overall revascularization rates (adjusted OR, 0.94; 95% CI, 0.90 to 0.97). No measurable differences, however, were found in in-hospital mortality between regular hours and off-hours in the overall AMI, ST-elevated MI, and non–ST-elevated MI cohorts (adjusted OR, 0.99; 95% CI, 0.93 to 1.06; adjusted OR, 1.05; 95% CI, 0.94 to 1.18; and adjusted OR, 0.97; 95% CI, 0.90 to 1.04, respectively). Similar observations were made across most age and sex subgroups and with an alternative definition for arrival time (weekends/holidays versus weekdays).

Conclusions— Despite slightly fewer primary percutaneous coronary interventions and overall revascularizations and significantly longer door-to-balloon times, patients presenting with AMI during off-hours had in-hospital mortality similar to those presenting during regular hours.

Hospital treatment of patients with ischemic stroke or transient ischemic attack using the "Get With The Guidelines" program

BACKGROUND

Adherence to evidence-based interventions for hospitalized patients who have experienced a stroke is suboptimal. We examined the association of process improvement and Internet-based data collection and decision support with stroke care.

METHODS

A 1-year intervention study to assess performance measure adherence in hospitals using the "Get With The Guidelines-Stroke" program. The program included 18 410 patients with ischemic stroke or transient ischemic attack admitted to 99 volunteer community and teaching hospitals. Data from eligible patients in the preintervention baseline period were compared with data from 4 subsequent quarters for 12 acute care or secondary prevention measures and an all-or-none measure of care based on 7 prespecified measures.

RESULTS

Significant improvements from baseline to the fourth quarter were seen in 11 of 13 measures: use of thrombolytic medications for patients with ischemic stroke presenting within 2 hours of onset, 23.5% vs 40.8% (P < .001); early use of antithrombotic medications, 88.2% vs 95.2% (P < .001); antithrombotic medications prescribed at discharge, 91.0% vs 97.9% (P < .001); anticoagulation agents for atrial fibrillation, 81.4% vs 96.5% (P < .001); smoking cessation counseling, 38.3% vs 54.5% (P < .001); lipid treatment for low-density lipoprotein levels 100 mg/dL or greater, 58.7% vs 77.0% (P < .001); diabetes mellitus treatment, 48.5% vs 83.5% (P = .001); and weight reduction counseling 32.5% vs 43.4% (P < .001). The all-or-none measure increased from 50.2% to 58.0% (P < .001). Complications from thrombolytic medications and prophylaxis for deep venous thrombosis did not change.

CONCLUSION

Statistically and clinically significant improvement in 11 of 13 quality improvement measures for the treatment of patients hospitalized for cerebrovascular disease was seen in hospitals participating in the Get With The Guidelines program.

Atherosclerosis secondary prevention performance measures after coronary bypass graft surgery compared with percutaneous catheter intervention and nonintervention patients in the Get With the Guidelines database

BACKGROUND

The American Heart Association Get With the Guidelines-Coronary Artery Disease program facilitates patient and physician compliance with proven atherosclerosis risk reduction strategies with collaborative learning sessions, teaching materials, predischarge online check lists, and web-based performance measure feedback for continuous quality improvement. Patients having coronary artery bypass graft surgery (CABG) may be subject to different care processes, nursing unit pathways, and personnel than patients having percutaneous catheter intervention or neither intervention, which may affect compliance.

METHODS AND RESULTS

The Get With the Guidelines-Coronary Artery Disease database was queried to determine whether compliance with secondary prevention performance measures for CABG patients was different from that for nonsurgical patients. A total of 119,106 patients were treated with CABG (14,118), percutaneous catheter intervention (58,702), or neither intervention (46,286). Compliance with medication prescriptions, including aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and lipid-lowering drugs, and smoking cessation counseling for eligible patients was analyzed. Medically appropriate exclusions and contraindications were included in the analysis. After adjusting for 14 clinical variables, CABG patients were less likely to receive most secondary prevention measures relative to percutaneous catheter intervention patients. In contrast, CABG patients were more likely to receive aspirin, beta-blocker, and smoking cessation counseling than neither intervention patients. Composite adherence and defect-free rates were highest for percutaneous catheter intervention patients and lowest for neither intervention patients after adjustment.

CONCLUSIONS

There are significant differences in compliance at hospital discharge with secondary prevention performance measures for CABG patients compared with nonsurgical patients. Process of care differences may explain these differences and should be examined further because significant opportunities for improved compliance are evident. CABG patients in particular represent a group for whom secondary prevention has proven benefits, and they may benefit from future quality improvement interventions.

Sex and racial differences in the use of implantable cardioverter-defibrillators among patients hospitalized with heart failure

CONTEXT

Practice guidelines recommend implantable cardioverter-defibrillator (ICD) therapy for patients with heart failure and left ventricular ejection fraction of 30% or less. The influence of sex and race on ICD use among eligible patients is unknown.

OBJECTIVE

To examine sex and racial differences in the use of ICD therapy.

DESIGN, SETTING, AND PATIENTS

Observational analysis of 13,034 patients admitted with heart failure and left ventricular ejection fraction of 30% or less and discharged alive from hospitals in the American Heart Association's Get With the Guidelines-Heart Failure quality-improvement program. Patients were treated between January 2005 and June 2007 at 217 participating hospitals.

MAIN OUTCOME MEASURES

Use of ICD therapy or planned ICD therapy at discharge.

RESULTS

Among patients eligible for ICD therapy, 4615 (35.4%) had ICD therapy at discharge (1614 with new ICDs, 527 with planned ICDs, and 2474 with prior ICDs). ICDs were used in 375 of 1329 eligible black women (28.2%), 754 of 2531 white women (29.8%), 660 of 1977 black men (33.4%), and 2356 of 5403 white men (43.6%) (P < .001). After adjustment for patient characteristics and hospital factors, the adjusted odds of ICD use were 0.73 (95% confidence interval, 0.60-0.88) for black men, 0.62 (95% confidence interval, 0.56-0.68) for white women, and 0.56 (95% confidence interval, 0.44-0.71) for black women, compared with white men. The differences were not attributable to the proportions of women and black patients at participating hospitals or to differences in the reporting of left ventricular ejection fraction.

CONCLUSIONS

Less than 40% of potentially eligible patients hospitalized for heart failure received ICD therapy, and rates of use were lower among eligible women and black patients than among white men.

Improved treatment of hospitalized coronary artery disease patients with the get with the guidelines program

Adherence to evidence-based interventions for hospitalized cardiovascular disease patients is not optimal. This study assesses the impact of a national quality improvement program on adherence to guidelines in these patients. Data from 92 hospitals from across the United States participating in the Get With The Guidelines program for at least 1 year for 11 acute and secondary prevention measures from a preintervention baseline period and the subsequent 4 quarters of a quality improvement intervention were analyzed. A patient group of 45,988 patients with acute myocardial infarction, unstable angina, revascularization, or peripheral vascular disease was included in this evaluation. Significant improvement from baseline was seen in 10 of 11 measures by the fourth quarter: use of early aspirin for acute myocardial infarction, 76.4% to 88.0% (P < 0.0001); early beta-blocker for acute myocardial infarction, 64.4% to 79.5% (P < 0.0001); beta-blocker at discharge, 75% to 82.1% (P < 0.0001); smoking cessation counseling, 58.7% to 74.3% (P < 0.0001); angiotensin-converting enzyme inhibitor use for acute myocardial infarction, 64.5% to 69.9% (P < 0.0001); lipid treatment, 58.5% to 63.4% (P < 0.0001); lipid treatment for low-density lipoprotein > or =100 mg/dL, 60.4% to 67.0% (P < 0.0001); low-density-lipoprotein measurement, 48.8% to 53.2% (P < 0.0001); discharge blood pressure <140/90 mm Hg, 65.9% to 68.0% (P = 0.03); and referral to cardiac rehabilitation or exercise counseling, 65.0% to 88.3% (P < 0.001). Discharge aspirin use at 89.9% did not change. Statistically and clinically significant improvement in 10 of 11 quality-improvement measures for the treatment of patients hospitalized for cardiovascular disease was seen in hospitals participating in Get With The Guidelines.

Quality of acute stroke care improvement framework for the Paul Coverdell National Acute Stroke Registry: facilitating policy and system change at the hospital level

The Paul Coverdell National Acute Stroke Registry prototypes baseline data collection demonstrated a significant gap in the use of evidenced-based interventions. Barriers to the use of these interventions can be characterized as relating to lack of knowledge, attitudes, and ineffective behaviors and systems. Quality improvement programs can address these issues by providing didactic presentations to disseminate the science and peer interactions to address the lack of belief in the evidence, guidelines, and likelihood of improved patient outcomes. Even with knowledge and intention to provide evidenced-based care, the absence of effective systems is a significant behavioral barrier. A program for quality improvement that includes multidisciplinary teams of clinical and quality improvement professionals has been successfully used to carry out redesign of stroke care delivery systems. Teams are given a methodology to set goals, test ideas for system redesign, and implement those changes that can be successfully adapted to the hospital's environment. Bringing teams from several hospitals together substantially accelerates the process by sharing examples of successful change and by providing strategies to support the behavior change necessary for the adoption of new systems. The participation of many hospitals also creates momentum for the adoption of change by demonstrating observable and successful improvement. Data collection and feedback are useful to demonstrate the need for change and evaluate the impact of system change, but improvement occurs very slowly without a quality improvement program. This quality improvement framework provides hospitals with the capacity and support to redesign systems, and has been shown to improve stroke care considerably, when coupled with an Internet-based decision support registry, and at a much more rapid pace than when hospitals use only the support registry.

The Paul Coverdell National Acute Stroke Registry: initial results from four prototypes

BACKGROUND

This paper summarizes the experiences of the Paul Coverdell National Acute Stroke Registry first four prototype registries in Georgia (GA), Massachusetts (MA), Michigan (MI), and Ohio (OH), and includes information on their sampling design, case ascertainment, and data collection methods, as well as some key findings.

METHODS

Using a combination of different sampling methods, each prototype obtained a representative statewide sample of hospitals. Acute stroke admissions were identified through prospective (MA, MI) or retrospective (GA, OH) methods. A common set of case definitions and data elements were used by each registry. Weighted site-specific frequencies and 95% confidence intervals were generated for each outcome. A summary estimate, representing a weighted average of the four site-specific estimates, was also calculated.

RESULTS

Of the total 6867 admissions, 1487 (21.6%) were from the GA registry, 1206 (17.6%) from MA, 2566 (37.4%) from MI, and 1608 (23.4%) from the OH prototype. Just less than 60% of admissions were ischemic strokes (site-specific estimates ranged from 52% to 70%), with transient ischemic attack (18.5%) and intracerebral hemorrhage (8.8%) making up most of the remainder. Twenty-one percent of patients admitted were younger than 60 years of age, and 55.3% were women. The proportion of black subjects varied from 7.1% (MI) to 30.6% (GA). Twenty-three percent of admissions arrived at the emergency department within 3 hours of onset. Overall 4.5% of ischemic stroke admissions were treated with recombinant tissue plasminogen activator; site-specific treatment rates were 3.0% (GA), 3.2% (OH), 3.4% (MI), and 8.5% (MA). Only a small minority of treated patients (range, 10.8% [OH] to 19.6% [MI]) received recombinant tissue plasminogen activator within the recommended 1 hour door-to-needle time. A minority of eligible subjects were screened for dysphagia (45.4%), underwent lipid testing (33.6%), or received smoking-cessation counseling (21.4%). In contrast, compliance with antithrombotic treatments at discharge was high (91.5%).

CONCLUSIONS

A minority of acute stroke patients are treated according to established guidelines. Quality improvement interventions, targeted primarily at the healthcare systems level, are needed to improve acute stroke care in the United States.

Payment for Quality: Guiding Principles and Recommendations

Payment-for-quality programs are emerging in the wake of rising healthcare costs and a demonstrated need for quality improvement in healthcare delivery in the United States. These programs, also known as “pay-for-performance” or “pay-for-value” programs, attempt to realign financial incentives with the quality of care delivered. The American Heart Association’s Reimbursement, Coverage, and Access Policy Development Workgroup provides in this statement a set of principles and recommendations for the development, implementation, and evaluation of these programs. The statement also suggests future areas for research around the realignment of financial incentives to improve both the quality of care delivered and patient outcomes.

Using “get with the guidelines” to prevent recurrent cardiovascular disease

Clinical trials and guidelines provide strategies to reduce the rate of recurrent events in patients with cardiovascular disease. Despite multiple therapeutic options to enhance secondary prevention, many patients leave the hospital without these basic interventions. Delivery of secondary prevention is critically dependent on systems to ensure reliable delivery. The implementation of successful systems requires physician leadership, compatibility with hospital strategic priorities, multidisciplinary teams, use of tools such as preprinted orders and discharge protocols, and concurrent data collection and feedback. The process of testing and implementing effective systems is best done in a collaborative where teams from multiple hospitals share successes and lessons that were learned. Community level collaboratives also create momentum to gain support at the hospital level. The combination of collaborative learning with technology for data collection, feedback, and decision making is useful to move multiple hospitals to higher levels of performance in critical measures of secondary prevention.

Acute Stroke Care in the US

Background and Purpose— The Paul Coverdell National Acute Stroke Registry is being developed to improve the quality of acute stroke care. This article describes key features of acute stroke care from 4 prototype registries in Georgia (Ga), Massachusetts (Mass), Michigan (Mich), and Ohio.

Methods— Each prototype developed its own sampling scheme to obtain a representative sample of hospitals. Acute stroke admissions were identified using prospective (Mass, Mich) or retrospective (Ga, Ohio) methods. All prototypes used a common set of case definitions and data elements. Weighted site-specific frequencies were generated for each outcome.

Results— A total of 6867 admissions from 98 hospitals were included; the majority were ischemic strokes (range, 52% to 70%) with transient ischemic attack and intracerebral hemorrhage comprising the bulk of the remainder. Between 19% and 26% of admissions were younger than age 60 years, and between 52% and 58% were female. Black subjects varied from 7.1% (Mich) to 30.6% (Ga). Between 20% and 25% of admissions arrived at the emergency department within 3 hours of onset. Treatment with recombinant tissue plasminogen activator (rtPA) was administered to between 3.0% (Ga) and 8.5% (Mass) of ischemic stroke admissions. Of 118 subjects treated with intravenous rtPA, <20% received it within 60 minutes of arrival. Compliance with secondary prevention practices was poorest for smoking cessation counseling and best for antithrombotics.

Conclusions— A minority of acute stroke patients are treated according to established guidelines. Quality improvement interventions, targeted primarily at the health care systems level, are needed to improve acute stroke care in the United States.

Aligning financial incentives with "Get With The Guidelines" to improve cardiovascular care

OBJECTIVE

To describe the impact of a commercial insurer's financial incentives to hospitals in conjunction with collaboration with the American Heart Association (AHA) to accelerate implementation of Get With The Guidelines-Coronary Artery Disease (GWTG-CAD), a quality improvement program to rapidly improve cardiovascular secondary prevention in hospitalized patients.

STUDY DESIGN

Observational assessment of quality improvement program participation and implementation in response to financial incentives.

METHODS

The study population included all hospitals that participated with the Hawaii Medical Service Association (HMSA, Blue Cross Blue Shield of Hawaii) Hospital Quality and Service Recognition Program and had more than 30 annual admissions for acute coronary artery disease. These 13 hospitals were given encouragement and financial incentives to implement GWTG-CAD. Financial incentives were determined by a prorated amount of the total HMSA hospital reimbursement for all acute services, as part of a more comprehensive hospital "pay for performance" program.

RESULTS

Incentives to 10 of 13 eligible hospitals included reimbursement for half the annual cost of the AHA Patient Management Tool. In addition, HMSA's pay for performance program--the Hospital Quality and Service Recognition Program--distributed monetary awards totaling 354,883 dollars, based on points awarded for GWTG-CAD workshop attendance documentation (10 hospitals), recognition by the AHA as a GWTG-CAD hospital, and attainment of 85% adherence to the GWTG-CAD performance measures (4 hospitals).

CONCLUSIONS

Community-based promotion of GWTG-CAD and financial incentives provided by a commercial insurer resulted in the rapid implementation of a secondary prevention program for coronary artery disease in most hospitals in the State of Hawaii within a single year.

Get with the guidelines for cardiovascular secondary prevention: pilot results

BACKGROUND

The use of Web-based technology and a collaborative model to improve hospital adherence to secondary prevention guidelines has not been previously evaluated.

METHODS

Twenty-four hospitals in Massachusetts participated in a collaborative that met quarterly, with didactic and best-practice presentations and interactive multidisciplinary team workshops. A customized tool kit and interactive, Web-based management tool were used for data collection and on-line feedback. Data from 1738 patients admitted with coronary artery disease were collected by hospital staff from July 1, 2000, to June 30, 2001. Outcome measures included differences between baseline and 10- to 12-month follow-up measurements of use of aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, cholesterol measurement and treatment, smoking cessation counseling, blood pressure control, and cardiac rehabilitation referral.

RESULTS

Clinically and statistically significant increases from baseline to 10- to 12-month follow-up were demonstrated in smoking cessation counseling (48% [95% confidence interval [CI], 36.6%-58.4%] to 87% [95% CI, 73.1%-100.7%]), lipid treatment (54% [95% CI, 46.6%-70.2%] to 79% [95% CI, 70.2%-88.3%]), lipid measurement (59% [95% CI, 51.5%-66.0%] to 81% [95% CI, 72.0%-89.5%]), and cardiac rehabilitation referral (34% [95% CI, 25.9%-39.7%] to 73% [95% CI, 63.2%-82.9%]). An improving trend was seen in blood pressure control (60% [95% CI, 55.3%-65.6%] to 68% [95% CI, 60.2%-76.1%]). High baseline use was maintained for use of aspirin, beta-blockers, and angiotensin-converting enzyme inhibitors.

CONCLUSION

Implementation of a collaborative quality improvement initiative, interactive training of hospital teams with physician champions, and the use of an interactive Web-based Patient Management Tool enhanced adherence to prevention guidelines in hospitalized patients with coronary artery disease.

Using "get with the guidelines" to improve cardiovascular secondary prevention

BACKGROUND

"Get With The Guidelines (GWTG)" was developed and piloted by the American Heart Association (AHA), New England Affiliate; MassPRO, Inc.; and other organizations to reduce the gap in the application of secondary prevention guidelines in hospitalized cardiovascular disease patients. Collaborative learning programs and technology solutions were created for the project.

THE PATIENT MANAGEMENT TOOL (PMT)

The interactive Web-based patient management tool (PMT) was developed using quality measures derived from the AHA/American College of Cardiology secondary prevention guidelines. It provided data entry, embedded reminders and guideline summaries, and online reports of quality measure performance, including comparisons with the aggregate performance of all hospitals.

LEARNING SESSIONS

Multidisciplinary teams from 24 hospitals participated in the 2000-2001 pilot. Four collaborative learning sessions and monthly conference calls supported team interaction. Best-practices sharing and the use of an Internet tool enabled hospitals to change systems and collect data on 1,738 patients.

SUMMARY AND CONCLUSIONS

The GWTG program, a template of learning sessions with didactic presentations, best-practices sharing, and collaborative multidisciplinary team meetings supported by the Internet-based data collection and reporting system, can be extended to multiple regions without requiring additional development. Following the completion of the pilot, the AHA adopted GWTG as a national program.

A collaborative model for hospital-based cardiovascular secondary prevention

This article presents a collaborative model for hospital-based cardiovascular secondary prevention. The model employs a stake holder consortium to provide hospitals with a unified approach to improve care and conform to regulatory requirements. Hospital teams use a Web-based tool that embeds data collection in the process of care and supports rapid cycle improvement. Recognition of participation and achievement by the American Heart Association helps to obtain administrative support for the program.

Secondary prevention in a cardiology group practice and hospital setting after a heart-care initiative

The American Heart Association (AHA) Consensus Panel Statement for Preventing Heart Attack and Death in Patients with Coronary Disease provides recommendations for the secondary prevention of heart disease in at-risk patients. Blackstone Cardiology Associates of Pawtucket, Rhode Island, undertook an initiative in their practice implementing secondary-prevention guidelines in patients with coronary artery disease. This retrospective study evaluates practice patterns for the management of hyperlipidemia for a cardiology group in an ambulatory and hospital setting after the institution of a physician-supervised, nurse-based disease management program. Practice patterns in patients with established coronary heart disease treated in a lipid center compared with non-lipid-center settings were evaluated. Parameters evaluated included documenting low-density lipoprotein (LDL) cholesterol, presence of lipid-lowering therapy, and achieving the National Cholesterol Education Program II (NCEP II) goal of LDL-cholesterol levels < or =100 mg/dL in patients with preexisting coronary artery disease. A total of 352 patients met inclusion criteria in the lipid-center setting and were compared with 289 non-lipid-center consecutively chosen patients. Age and gender differences were also evaluated. Inpatient medical records from a 254-bed Brown University-affiliated teaching hospital were also evaluated for lipid profile, achievement of NCEP II goal, and use of lipid-lowering medication on admission and discharge. The most recent LDL-cholesterol values of patients followed in the lipid-center and in the non-lipid-center setting of the Blackstone Cardiology Associates were compared. Blackstone Cardiology Associates consists of 4 cardiologists and 4 advanced-practice nurses. Achievement of LDL-cholesterol goal was higher in both the lipid-center and non-lipid-center settings compared with baseline. A smaller percentage of patients at goal in the lipid setting is likely due to referral bias resulting in patients with more difficult-to-manage mixed dyslipidemias and behavior-management issues ending up in the lipid center. There were no apparent sex differences at goal, and more elderly (age > or =65 years) achieved goal in the lipid clinic center. In the non-lipid-center setting, more males were at goal and had a lower mean LDL-cholesterol level.

Comparison of dobutamine and exercise using technetium-99m sestamibi imaging for the evaluation of coronary artery disease

Studies using dobutamine thallium-201 myocardial perfusion imaging have suggested a high sensitivity and specificity for the detection of coronary artery disease. However, few data are available comparing dobutamine with exercise stress for the detection and localization of perfusion defects. This study compared the effects of dobutamine and exercise stress using technetium-99m sestamibi single-photon emission computed tomographic imaging in the same patients in a prospective crossover trial. Twenty-four patients with a high likelihood of coronary artery disease underwent tomographic myocardial imaging at rest, after symptom-limited treadmill exercise, and after intravenous dobutamine (maximum 30 micrograms/kg/min). Tomograms of the left ventricle were divided into 20 segments and were interpreted without knowledge of patient identity or stress protocol. Dobutamine was well tolerated by all patients. Segment-by-segment concordance between exercise and dobutamine images was highly significant (kappa = 0.56, p < 0.0001). Global first-order agreement (normal vs abnormal) between exercise and dobutamine studies was 96% (kappa = 0.65, p = 0.02); global second-order agreement (normal vs fixed vs ischemic defect) was 88% (kappa = 0.45, p = 0.02). Regional first- and second-order agreement were 96 and 93%, respectively (p < 0.001 for both). Twenty patients underwent coronary angiography. Comparisons between exercise and angiography and between dobutamine and angiography were similar for both global agreement (95 vs 100%, p = NS) and regional agreement (77 vs 72%, p = NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Two-dimensional echocardiographic detection of preclinical aortic root abnormalities in rheumatoid variant diseases

Two-dimensional echocardiographic findings of subaortic fibrous ridging, aortic leaflet thickening, and aortic root dilatation and thickening are described in a group of 36 patients with rheumatoid variant diseases. The group consisted of 25 patients with ankylosing spondylitis, nine patients with Reiter's syndrome, and two patients with inflammatory bowel disease and spondylitis. No patient had clinical or laboratory evidence of aortic regurgitation or heart block. Subaortic fibrous ridging or marked leaflet thickening was noted in 11 of 36 patients; in contrast, no such changes were found in an age-matched control group of 29 men. The subgroup of patients with subaortic fibrous ridging or leaflet thickening (11 patients) had significantly longer disease duration (28.1 versus 17.7 years) and higher incidence of aortic root echo-density (82 versus 36 percent) than the remaining patients. It is concluded that a significant portion of patients with ankylosing spondylitis or Reiter's syndrome have echocardiographic evidence of aortic root involvement prior to the clinical onset of aortic regurgitation.

Thallium-201 myocardial imaging in patients on chronic hemodialysis

10 long-term hemodialysis patients had immediate and redistribution thallium-201 myocardial imaging performed after a course of hemodialysis. Subjects had EKGs done on the same day before and after dialysis. 3 of the 10 subjects had resting thallium-201 myocardial imaging obtained on non-dialysis days. 60% of the electrocardiograms showed changes with dialysis. All 13 thallium studies were abnormal, showing multiple transient filling defects at rest. Most subjects had permanent filling defects as well. It is concluded that hemodialysis patients have a high frequency of abnormal thallium-201 myocardial images at rest. The cause of these abnormal studies is uncertain.

Chest pain as a presentation of reactive hypoglycemia

Reported herein is a patient with multiple hospital admissions for atypical chest pain syndrome who underwent extensive noninvasive and invasive cardiologic testing to exclude ischemic heart disease as an etiology. During one episode of chest pain, the patient was found to have hypoglycemia with a blood sugar level of 46 ml/dl. Two subsequent oral glucose tolerance tests reproduced chest pain during hypoglycemia with values of 47 ml/dl and 27 ml/dl. The patient had previously had no significant clinical response to typical antianginal medications. Following evidence of concurrent hypoglycemia, the chest pain syndrome has significantly decreased with the patient on a low carbohydrate diet.
