Factors Affecting Choice of Community Residential Care Setting

To investigate factors associated with residents’ choice of type of Medicaid-funded community residential care setting in western Washington State. Method: Prospective cohort design including residents new to any of three setting types (264 residents entering 170 different facilities), using data from state and Medicaid databases and in-person interviews. The authors used analysis of variance and multinomial logistic regression to examine bivariate associations and estimate effects of resident and facility characteristics on choice of facility type at baseline. Results: Several resident characteristics appear to be associated with choice of community residential care setting, including age, marital status, education, functional status, and reported memory and behavior problems. Facility policies differ significantly among types of facilities and also appear to be associated with choice of setting. Discussion: Selection processes operate in choice of community residential care setting, with residents choosing facility type based on the fit of their needs with facility characteristics.

Reimagining Anticoagulation Clinics in the Era of Direct Oral Anticoagulants

Anticoagulation clinics were initially developed to provide safe and effective care for warfarin-treated patients with atrial fibrillation, venous thromboembolism, and mechanical valve replacement. Traditionally, these patients required ongoing laboratory monitoring and warfarin dose adjustment by expert providers. With the introduction of direct oral anticoagulants (dabigatran, rivaroxaban, apixaban, and edoxaban), many have questioned the need for anticoagulation clinic. However, we think that the growing number of oral anticoagulant choices creates an urgent need for expanding the traditional role of the anticoagulation clinic. We outline 3 key purposes that a reimagined anticoagulation clinic would serve: (1) to assist patients and clinicians with selecting the most appropriate drug and dose from a growing list of anticoagulant options (including warfarin), (2) to help patients minimize the risk of serious bleeding complications with careful long-term monitoring and peri-procedural management, and (3) to encourage ongoing adherence to these life-saving medications. We also describe how repurposing anticoagulation clinics as broader medication safety clinics would promote safe and effective care across a range of cardiovascular conditions for high-risk medications (eg, spironolactone, amiodarone). Finally, we highlight a few existing health systems that are overcoming key challenges to implementing a reimagined anticoagulation or medication safety clinic structure.

Developing educational competencies for dissemination and implementation research training programs: an exploratory analysis using card sorts

BACKGROUND

With demand increasing for dissemination and implementation (D&I) training programs in the USA and other countries, more structured, competency-based, and tested curricula are needed to guide training programs. There are many benefits to the use of competencies in practice-based education such as the establishment of rigorous standards as well as providing an additional metrics for development and growth. As the first aim of a D&I training grant, an exploratory study was conducted to establish a new set of D&I competencies to guide training in D&I research.

METHODS

Based upon existing D&I training literature, the leadership team compiled an initial list of competencies. The research team then engaged 16 additional colleagues in the area of D&I science to provide suggestions to the initial list. The competency list was then additionally narrowed to 43 unique competencies following feedback elicited from these D&I researchers. Three hundred additional D&I researchers were then invited via email to complete a card sort in which the list of competencies were sorted into three categories of experience levels. Participants had previous first-hand experience with D&I or knowledge translation training programs in the past. Participants reported their self-identified D&I expertise level as well as the country in which their home institution is located. A mean score was calculated for each competency based on their experience level categorization. From these mean scores, beginner-, intermediate-, and advanced-level tertiles were created for the competencies.

RESULTS

The card sort request achieved a 41 % response rate (n = 124). The list of 43 competencies was organized into four broad domains and sorted based on their experience level score. Eleven competencies were classified into the "Beginner" category, 27 into "Intermediate," and 5 into "Advanced."

CONCLUSIONS

Education and training developers can use this competency list to formalize future trainings in D&I research, create more evidence-informed curricula, and enable overall capacity building and accompanying metrics in the field of D&I training and research.

Implementation of an audit with feedback knowledge translation intervention to promote medication error reporting in health care: a protocol

Background

Health professionals strive to deliver high-quality care in an inherently complex and error-prone environment. Underreporting of medical errors challenges attempts to understand causative factors and impedes efforts to implement preventive strategies. Audit with feedback is a knowledge translation strategy that has potential to modify health professionals’ medical error reporting behaviour. However, evidence regarding which aspects of this complex, multi-dimensional intervention work best is lacking. The aims of the Safe Medication Audit Reporting Translation (SMART) study are to:

1. Implement and refine a reporting mechanism to feed audit data on medication errors back to nurses

2. Test the feedback reporting mechanism to determine its utility and effect

3. Identify characteristics of organisational context associated with error reporting in response to feedback

Methods/design

A quasi-experimental design, incorporating two pairs of matched wards at an acute care hospital, is used. Randomisation occurs at the ward level; one ward from each pair is randomised to receive the intervention. A key stakeholder reference group informs the design and delivery of the feedback intervention. Nurses on the intervention wards receive the feedback intervention (feedback of analysed audit data) on a quarterly basis for 12 months. Data for the feedback intervention come from medication documentation point-prevalence audits and weekly reports on routinely collected medication error data. Weekly reports on these data are obtained for the control wards. A controlled interrupted time series analysis is used to evaluate the effect of the feedback intervention. Self-report data are also collected from nurses on all four wards at baseline and at completion of the intervention to elicit their perceptions of the work context. Additionally, following each feedback cycle, nurses on the intervention wards are invited to complete a survey to evaluate the feedback and to establish their intentions to change their reporting behaviour. To assess sustainability of the intervention, at 6 months following completion of the intervention a point-prevalence chart audit is undertaken and a report of routinely collected medication errors for the previous 6 months is obtained. This intervention will have wider application for delivery of feedback to promote behaviour change for other areas of preventable error and adverse events.

Urologist Workforce Variation Across the VHA

Distribution of urologists varies significantly at the facility rather than at the regional level, according to a large-scale study, but regional approaches, e-consults, and telemedicine may mitigate veteran access issues.

Understanding feedback report uptake: process evaluation findings from a 13-month feedback intervention in long-term care settings

Background

Long-term care settings provide care to a large proportion of predominantly older, highly disabled adults across the United States and Canada. Managing and improving quality of care is challenging, in part because staffing is highly dependent on relatively non-professional health care aides and resources are limited. Feedback interventions in these settings are relatively rare, and there has been little published information about the process of feedback intervention. Our objectives were to describe the key components of uptake of the feedback reports, as well as other indicators of participant response to the intervention.

Methods

We conducted this project in nine long-term care units in four facilities in Edmonton, Canada. We used mixed methods, including observations during a 13-month feedback report intervention with nine post-feedback survey cycles, to conduct a process evaluation of a feedback report intervention in these units. We included all facility-based direct care providers (staff) in the feedback report distribution and survey administration. We conducted descriptive analyses of the data from observations and surveys, presenting this in tabular and graphic form. We constructed a short scale to measure uptake of the feedback reports. Our analysis evaluated feedback report uptake by provider type over the 13 months of the intervention.

Results

We received a total of 1,080 survey responses over the period of the intervention, which varied by type of provider, facility, and survey month. Total number of reports distributed ranged from 103 in cycle 12 to 229 in cycle 3, although the method of delivery varied widely across the period, from 12% to 65% delivered directly to individuals and 15% to 84% left for later distribution. The key elements of feedback uptake, including receiving, reading, understanding, discussing, and reporting a perception that the reports were useful, varied by survey cycle and provider type, as well as by facility. Uptake, as we measured it, was consistently high overall, but varied widely by provider type and time period.

Conclusions

We report detailed process data describing the aspects of uptake of a feedback report during an intensive, longitudinal feedback intervention in long-term care facilities. Uptake is a complex process for which we used multiple measures. We demonstrate the feasibility of conducting a complex longitudinal feedback intervention in relatively resource-poor long-term care facilities to a wider range of provider types than have been included in prior feedback interventions.

Understanding context in knowledge translation: a concept analysis study protocol

AIM

To conduct a concept analysis of clinical practice contexts (work environments) that facilitate or militate against the uptake of research evidence by healthcare professionals in clinical practice. This will involve developing a clear definition of context by describing its features, domains and defining characteristics.

BACKGROUND

The context where clinical care is delivered influences that care. While research shows that context is important to knowledge translation (implementation), we lack conceptual clarity on what is context, which contextual factors probably modify the effect of knowledge translation interventions (and hence should be considered when designing interventions) and which contextual factors themselves could be targeted as part of a knowledge translation intervention (context modification).

DESIGN

Concept analysis.

METHODS

The Walker and Avant concept analysis method, comprised of eight systematic steps, will be used: (1) concept selection; (2) determination of aims; (3) identification of uses of context; (4) determination of defining attributes of context; (5) identification/construction of a model case of context; (6) identification/construction of additional cases of context; (7) identification/construction of antecedents and consequences of context; and (8) definition of empirical referents of context. This study is funded by the Canadian Institutes of Health Research (January 2014).

DISCUSSION

This study will result in a much needed framework of context for knowledge translation, which identifies specific elements that, if assessed and used to tailor knowledge translation activities, will result in increased research use by nurses and other healthcare professionals in clinical practice, ultimately leading to better patient care.

Data for improvement and clinical excellence: report of an interrupted time series trial of feedback in long-term care

BACKGROUND

There is considerable evidence about the effectiveness of audit coupled with feedback for provider behavior change, although few feedback interventions have been conducted in long-term care settings. The primary purpose of the Data for Improvement and Clinical Excellence-Long-Term Care (DICE-LTC) project was to assess the effects of a feedback intervention delivered to all direct care providers on resident outcomes. Our objective in this report is to assess the effect of feedback reporting on rates of pain assessment, depression screening, and falls over time.

METHODS

The intervention consisted of monthly feedback reports delivered to all direct care providers, facility and unit administrators, and support staff, delivered over 13 months in nine LTC units across four facilities. Data for feedback reports came from the Resident Assessment Instrument Minimum Data Set (RAI) version 2.0, a standardized instrument mandated in LTC facilities throughout Alberta. The primary evaluation used an interrupted time series design with a comparison group (units not included in the feedback intervention) and a comparison condition (pressure ulcers). We used segmented regression analysis to assess the effect of the feedback intervention.

RESULTS

The primary outcome of the study, falls, showed little change over the period of the intervention, except for a small increase in the rate of falls during the intervention period. The only outcome that improved during the intervention period was the proportion of residents with high pain scores, which decreased at the beginning of the intervention. The proportion of residents with high depression scores appeared to worsen during the intervention.

CONCLUSIONS

Maintaining all nine units in the study for its 13-month duration was a positive outcome. The feedback reports, without any other intervention included, did not achieve the desired reduction in proportion of falls and elevated depression scores. The survey on intention to change pain assessment practice which was conducted shortly after most of the feedback distribution cycles may have acted as a co-intervention supporting a reduction in pain scores. The processing and delivery of feedback reports could be accomplished at relatively low cost because the data are mandated and could be added to other intervention approaches to support implementation of evidence-based practices.

Impact of imaging guidelines on X-ray use among American provider network chiropractors: interrupted time series analysis

BACKGROUND CONTEXT

Overuse and misuse of spine X-ray imaging for nonspecific back and neck pain persists among chiropractors. Distribution of educational materials among physicians results in small-to-modest improvements in appropriate care, such as ordering spine X-ray studies, but little is known about its impact among North American chiropractors.

PURPOSE

To evaluate the impact of web-based dissemination of a diagnostic imaging guideline on the use of spine X-ray images among chiropractors.

STUDY DESIGN/SETTING

Quasi-experimental design that used interrupted time series to evaluate the effect of guidelines dissemination on spine X-ray imaging claims by chiropractors enlisted in managed care network in the United States.

PATIENT SAMPLE

Consecutive adult patients consulting for complaints of spine disorders.

OUTCOME MEASURES

A change in level (the mean number of spine X-ray imaging claims per month immediately after the introduction of the guidelines), change in trend (any differences between preintervention and postintervention slopes), estimation of monthly average intervention effect after the intervention.

METHODS

The imaging guideline was disseminated online in April 2008. Administrative claims data were extracted between January 2006 and December 2010. Segmented regression analysis with autoregressive error was used to estimate the impact of guideline recommendations on the rate of spine X-ray studies. Sensitivity analysis considered the effect of two additional quality improvement strategies, a policy change and an education intervention.

RESULTS

Time series analysis revealed a significant change in the level of spine X-ray study ordering weeks after introduction of the guidelines (-0.01; 95% confidence interval=-0.01, -0.002; p=.01), but no change in trend of the regression lines. The monthly mean rate of spine X-ray studies within 5 days of initial visit per new patient exams decreased by 10 per 1000, a 5.26% relative decrease after guideline dissemination. Controlling for two quality improvement strategies did not change the results.

CONCLUSIONS

Web-based guideline dissemination was associated with an immediate reduction in spine X-ray imaging claims. Sensitivity analysis suggests our results are robust. This passive strategy is likely cost-effective in a chiropractic network setting.

Regulated provider perceptions of feedback reports

AIM

This paper reports on regulated (or licensed) care providers' understanding and perceptions of feedback reports in a sample of Canadian long-term care settings using a cross-sectional survey design.

BACKGROUND

Audit with feedback quality improvement studies have seldom targeted front-line providers in long-term care to receive feedback information.

METHODS

Feedback reports were delivered to front-line regulated care providers in four long-term care facilities for 13 months in 2009-10. Providers completed a postfeedback survey.

RESULTS

Most (78%) regulated care providers (n = 126) understood the reports and felt they provided useful information for making changes to resident care (64%). Perceptions of the report differed, depending on the role of the regulated care provider. In multivariable logistic regression, the regulated nurses' understanding of more than half the report was negatively associated with 'usefulness of information for changing resident care', and perceiving the report as generally useful had a positive association.

CONCLUSIONS

Front-line regulated providers are an appropriate target for feedback reports in long-term care.

IMPLICATIONS FOR NURSING MANAGEMENT

Long-term care administrators should share unit-level information on care quality with unit-level managers and other professional front-line direct care providers.

Quality of prostate cancer care among rural men in the Veterans Health Administration

BACKGROUND

Patient travel distances, coupled with variation in facility-level resources, create barriers for prostate cancer care in the Veterans Health Administration integrated delivery system. For these reasons, the authors investigated the degree to which these barriers impact the quality of prostate cancer care.

METHODS

The Veterans Affairs Central Cancer Registry was used to identify all men who were diagnosed with prostate cancer in 2008. Patient residence was characterized using Rural Urban Commuting Area codes. The authors then examined whether rural residence, compared with urban residence, was associated with less access to cancer-related resources and worse quality of care for 5 prostate cancer quality measures.

RESULTS

Approximately 25% of the 11,368 patients who were diagnosed with prostate cancer in 2008 lived in either a rural area or a large town. Rural patients tended to be white (62% urban vs 86% rural) and married (47% urban vs 63% rural), and they tended to have slightly higher incomes (all P<.01) but similar tumor grade (P=.23) and stage (P=.12) compared with urban patients. Rural patients were significantly less likely to be treated at facilities with comprehensive cancer resources, although they received a similar or better quality of care for 4 of the 5 prostate cancer quality measures. The time to prostate cancer treatment was similar (rural patients vs urban patients, 96.6 days vs 105.7 days).

CONCLUSIONS

Rural patients with prostate cancer had less access to comprehensive oncology resources, although they received a similar quality of care, compared with their urban counterparts in the Veterans Health Administration integrated delivery system. A better understanding of the degree to which facility factors contribute to the quality of cancer care may assist other organizations involved in rural health care delivery.

Practice patterns in spine radiograph utilization among doctors of chiropractic enrolled in a provider network offering complementary care in the United States

OBJECTIVE

Nonspecific back pain is associated with high use of diagnostic imaging in primary care, yet current evidence suggests that routine imaging of the spine is unnecessary. The objective of this study is to describe current practice patterns in spine radiograph utilization among doctors of chiropractic enrolled in an American provider network.

METHODS

A cross-sectional analysis of administrative claims data from one of the largest providers of complementary health care networks for health plans in the United States was performed. Survey data containing provider demographics were linked with routinely collected data on spine radiograph utilization and patient characteristics aggregated at the provider level. We calculated rates and variations of spine radiographs over 12 months. Negative binomial regression was performed to identify significant predictors of high radiograph utilization and to estimate the associated incidence risk ratio.

RESULTS

Complete data for 6946 doctors of chiropractic and 249193 adult patients were available for analyses. In 2010, claims were paid for a total of 91542 new patient examinations and 23369 spine radiographs (including 17511 ordered within 5 days of initial patient examination). The rate of spine radiographs within 5 days of an initial patient visit was 204 per 1000 new patient examinations. Significant predictors of higher radiograph utilization rates included the following: practicing in the Midwest or South US census regions, practicing in an urban or suburban setting, chiropractic school attended, and being a male provider in full-time practice with more than 20 years of experience.

CONCLUSION

Chiropractic school attended and practice location were the most influential predictors of spine radiograph utilization among network chiropractors. This information may help to inform the development and evaluation of a tailored intervention to address overuse of radiograph utilization.

Unregulated provider perceptions of audit and feedback reports in long-term care: cross-sectional survey findings from a quality improvement intervention

BACKGROUND

Audit with feedback is a moderately effective approach for improving professional practice in other health care settings. Although unregulated caregivers give the majority of direct care in long-term care settings, little is known about how they understand and perceive feedback reports because unregulated providers have not been directly targeted to receive audit with feedback in quality improvement interventions in long-term care. The purpose of this paper is to describe unregulated care providers' perceptions of usefulness of a feedback report in four Canadian long-term care facilities.

METHODS

We delivered monthly feedback reports to unregulated care providers for 13 months in 2009-2010. The feedback reports described a unit's performance in relation to falls, depression, and pain as compared to eight other units in the study. Follow-up surveys captured participant perceptions of the feedback report. We conducted descriptive analyses of the variables related to participant perceptions and multivariable logistic regression to assess the association between perceived usefulness of the feedback report and a set of independent variables.

RESULTS

The vast majority (80%) of unregulated care providers (n = 171) who responded said they understood the reports. Those who discussed the report with others and were interested in other forms of data were more likely to find the feedback report useful for making changes in resident care.

CONCLUSIONS

This work suggests that unregulated care providers can understand and feel positively about using audit with feedback reports to make changes to resident care. Further research should explore ways to promote fuller engagement of unregulated care providers in decision-making to improve quality of care in long-term care settings.

Identifying factors likely to influence compliance with diagnostic imaging guideline recommendations for spine disorders among chiropractors in North America: a focus group study using the Theoretical Domains Framework

Background

The Theoretical Domains Framework (TDF) was developed to investigate determinants of specific clinical behaviors and inform the design of interventions to change professional behavior. This framework was used to explore the beliefs of chiropractors in an American Provider Network and two Canadian provinces about their adherence to evidence-based recommendations for spine radiography for uncomplicated back pain. The primary objective of the study was to identify chiropractors’ beliefs about managing uncomplicated back pain without x-rays and to explore barriers and facilitators to implementing evidence-based recommendations on lumbar spine x-rays. A secondary objective was to compare chiropractors in the United States and Canada on their beliefs regarding the use of spine x-rays.

Methods

Six focus groups exploring beliefs about managing back pain without x-rays were conducted with a purposive sample. The interview guide was based upon the TDF. Focus groups were digitally recorded, transcribed verbatim, and analyzed by two independent assessors using thematic content analysis based on the TDF.

Results

Five domains were identified as likely relevant. Key beliefs within these domains included the following: conflicting comments about the potential consequences of not ordering x-rays (risk of missing a pathology, avoiding adverse treatment effects, risks of litigation, determining the treatment plan, and using x-ray-driven techniques contrasted with perceived benefits of minimizing patient radiation exposure and reducing costs; beliefs about consequences); beliefs regarding professional autonomy, professional credibility, lack of standardization, and agreement with guidelines widely varied ( social/professional role & identity); the influence of formal training, colleagues, and patients also appeared to be important factors ( social influences); conflicting comments regarding levels of confidence and comfort in managing patients without x-rays ( belief about capabilities); and guideline awareness and agreements ( knowledge).

Conclusions

Chiropractors’ use of diagnostic imaging appears to be influenced by a number of factors. Five key domains may be important considering the presence of conflicting beliefs, evidence of strong beliefs likely to impact the behavior of interest, and high frequency of beliefs. The results will inform the development of a theory-based survey to help identify potential targets for behavioral-change strategies.

Data for improvement and clinical excellence: protocol for an audit with feedback intervention in home care and supportive living

Background

Although considerable evidence exists about the effectiveness of audit coupled with feedback, very few audit-with-feedback interventions have been done in either home care or supportive living settings to date. With little history of audit and feedback in home care or supportive living there is potential for greater effects, at least initially. This study extends the work of an earlier study designed to assess the effects of an audit-with-feedback intervention. It will be delivered quarterly over a one-year period in seven home care offices and 11 supportive living sites. The research questions are the same as in the first study but in a different environment. They are as follows:

1. What effects do feedback reports have on processes and outcomes over time?

2. How do different provider groups in home care and supportive living sites respond to feedback reports based on quality indicator data?

Methods

The research team conducting this study includes researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of quarterly feedback reports in 19 home care offices and supportive living sites across Alberta. Data for the feedback reports are based on the Resident Assessment Instrument Home Care tool, a standardized instrument mandated for use in home care and supportive living environments throughout Alberta. The feedback reports consist of one page, printed front and back, presenting both graphic and textual information. Reports are delivered to all employees working in each site. The primary evaluation uses a controlled interrupted time-series design, both adjusted and unadjusted for covariates. The concurrent process evaluation includes observation, focus groups, and self-reports to assess uptake of the feedback reports. The project described in this protocol follows a similar intervention conducted in our previous study, Data for Improvement and Clinical Excellence--Long-Term Care. We will offer dissemination strategies and spread of the feedback report approach in several ways suited to various audiences and stakeholders throughout Alberta.

Significance

This study will generate knowledge about the effects of an audit with feedback intervention in home care and supportive living settings. Our dissemination activities will focus on supporting sites to continue to use the Resident Assessment Instrument data in their quality improvement activities.

Workplace aggression experienced by frontline staff in dementia care

AIM

To describe the frequency of aggressive acts experienced by frontline staff working in two models of dementia care: Residential Alzheimer's Care Centers and Secured Dementia Units and to explore the associations between aggressive acts experienced by frontline staff and factors related to the work context and care providers.

BACKGROUND

Aggression towards healthcare providers in residential long-term care settings is well documented. However, few studies have examined associations between aggressive behaviours towards care providers and organisational factors.

DESIGN

A cross-sectional survey.

METHOD

The survey included demographic items and questions about aggressive acts experienced by staff and contextual factors. Analyses included: (1) descriptive statistics, (2) tests of difference (i.e. Student's t-test, Mann-Whitney U-test, chi-squared test and anova), (3) bivariate associations (i.e. Pearson and Spearman rank order correlations) and (4) multivariate linear regression.

RESULTS

Ninety-one health care aides and licensed practical nurses working in four nursing units using two models of dementia care participated (response rate 81%). The most frequently reported types of aggression were physical assault (50% of staff, n = 45) and emotional abuse (48% of staff, n = 44). Aggressive acts were significantly associated with working in Secured Dementia Units rather than Residential Alzheimer's Care Centers.

CONCLUSIONS

Frontline staff working in Secured Dementia Units were exposed to higher frequencies of various types of aggressive acts mainly initiated by residents. Future research needs to explore modifiable workplace factors associated with aggressive acts in a larger sample across a variety of long-term care settings.

RELEVANCE TO CLINICAL PRACTICE

To prevent staff perceived aggressive acts, leaders and managers in dementia care need to acknowledge the complex topic of workplace aggression and encourage an open discussion among frontline staff without assigning blame. Care provider strategies for dealing with aggressive behaviour have to be implemented in policies and clinical practice.

Core competencies in the science and practice of knowledge translation: description of a Canadian strategic training initiative

Background

Globally, healthcare systems are attempting to optimize quality of care. This challenge has resulted in the development of implementation science or knowledge translation (KT) and the resulting need to build capacity in both the science and practice of KT.

Findings

We are attempting to meet these challenges through the creation of a national training initiative in KT. We have identified core competencies in this field and have developed a series of educational courses and materials for three training streams. We report the outline for this approach and the progress to date.

Conclusions

We have prepared a strategy to develop, implement, and evaluate a national training initiative to build capacity in the science and practice of KT. Ultimately through this initiative, we hope to meet the capacity demand for KT researchers and practitioners in Canada that will lead to improved care and a strengthened healthcare system.

Predicting implementation from organizational readiness for change: a study protocol

Background

There is widespread interest in measuring organizational readiness to implement evidence-based practices in clinical care. However, there are a number of challenges to validating organizational measures, including inferential bias arising from the halo effect and method bias - two threats to validity that, while well-documented by organizational scholars, are often ignored in health services research. We describe a protocol to comprehensively assess the psychometric properties of a previously developed survey, the Organizational Readiness to Change Assessment.

Objectives

Our objective is to conduct a comprehensive assessment of the psychometric properties of the Organizational Readiness to Change Assessment incorporating methods specifically to address threats from halo effect and method bias.

Methods and Design

We will conduct three sets of analyses using longitudinal, secondary data from four partner projects, each testing interventions to improve the implementation of an evidence-based clinical practice. Partner projects field the Organizational Readiness to Change Assessment at baseline (n = 208 respondents; 53 facilities), and prospectively assesses the degree to which the evidence-based practice is implemented. We will conduct predictive and concurrent validities using hierarchical linear modeling and multivariate regression, respectively. For predictive validity, the outcome is the change from baseline to follow-up in the use of the evidence-based practice. We will use intra-class correlations derived from hierarchical linear models to assess inter-rater reliability. Two partner projects will also field measures of job satisfaction for convergent and discriminant validity analyses, and will field Organizational Readiness to Change Assessment measures at follow-up for concurrent validity (n = 158 respondents; 33 facilities). Convergent and discriminant validities will test associations between organizational readiness and different aspects of job satisfaction: satisfaction with leadership, which should be highly correlated with readiness, versus satisfaction with salary, which should be less correlated with readiness. Content validity will be assessed using an expert panel and modified Delphi technique.

Discussion

We propose a comprehensive protocol for validating a survey instrument for assessing organizational readiness to change that specifically addresses key threats of bias related to halo effect, method bias and questions of construct validity that often go unexplored in research using measures of organizational constructs.

The research agenda in ICU telemedicine: a statement from the Critical Care Societies Collaborative

ICU telemedicine uses audiovisual conferencing technology to provide critical care from a remote location. Research is needed to best define the optimal use of ICU telemedicine, but efforts are hindered by methodological challenges and the lack of an organized delivery approach. We convened an interdisciplinary working group to develop a research agenda in ICU telemedicine, addressing both methodological and knowledge gaps in the field. To best inform clinical decision-making and health policy, future research should be organized around a conceptual framework that enables consistent descriptions of both the study setting and the telemedicine intervention. The framework should include standardized methods for assessing the preimplementation ICU environment and describing the telemedicine program. This framework will facilitate comparisons across studies and improve generalizability by permitting context-specific interpretation. Research based on this framework should consider the multidisciplinary nature of ICU care and describe the specific program goals. Key topic areas to be addressed include the effect of ICU telemedicine on the structure, process, and outcome of critical care delivery. Ideally, future research should attempt to address causation instead of simply associations and elucidate the mechanism of action in order to determine exactly how ICU telemedicine achieves its effects. ICU telemedicine has significant potential to improve critical care delivery, but high-quality research is needed to best inform its use. We propose an agenda to advance the science of ICU telemedicine and generate research with the greatest potential to improve patient care.

Infrastructure for quality transformation: measurement and reporting in veterans administration intensive care units

BACKGROUND Veterans Health Administration (VA) intensive care units (ICUs) develop an infrastructure for quality improvement using information technology and recruiting leadership. METHODS Setting Participation by the 183 ICUs in the quality improvement program is required. Infrastructure includes measurement (electronic data extraction, analysis), quarterly web-based reporting and implementation support of evidence-based practices. Leaders prioritise measures based on quality improvement objectives. The electronic extraction is validated manually against the medical record, selecting hospitals whose data elements and measures fall at the extremes (10th, 90th percentile). results are depicted in graphic, narrative and tabular reports benchmarked by type and complexity of ICU. RESULTS The VA admits 103 689±1156 ICU patients/year. Variation in electronic business practices, data location and normal range of some laboratory tests affects data quality. A data management website captures data elements important to ICU performance and not available electronically. A dashboard manages the data overload (quarterly reports ranged 106-299 pages). More than 85% of ICU directors and nurse managers review their reports. Leadership interest is sustained by including ICU targets in executive performance contracts, identification of local improvement opportunities with analytic software, and focused reviews. CONCLUSION Lessons relevant to non-VA institutions include the: (1) need for ongoing data validation, (2) essential involvement of leadership at multiple levels, (3) supplementation of electronic data when key elements are absent, (4) utility of a good but not perfect electronic indicator to move practice while improving data elements and (5) value of a dashboard.

Data for improvement and clinical excellence: protocol for an audit with feedback intervention in long-term care

Background

There is considerable evidence about the effectiveness of audit coupled with feedback, although few audit with feedback interventions have been conducted in long-term care (LTC) settings to date. In general, the effects have been found to be modest at best, although in settings where there has been little history of audit and feedback, the effects may be greater, at least initially. The primary purpose of the Data for Improvement and Clinical Excellence (DICE) Long-Term Care project is to assess the effects of an audit with feedback intervention delivered monthly over 13 months in four LTC facilities. The research questions we addressed are:

1. What effects do feedback reports have on processes and outcomes over time?

2. How do different provider groups in LTC and home care respond to feedback reports based on data targeted at improving quality of care?

Methods/design

The research team conducting this study comprises researchers and decision makers in continuing care in the province of Alberta, Canada. The intervention consists of monthly feedback reports in nine LTC units in four facilities in Edmonton, Alberta. Data for the feedback reports comes from the Resident Assessment Instrument Minimum Data Set (RAI) version 2.0, a standardized instrument mandated for use in LTC facilities throughout Alberta. Feedback reports consist of one page, front and back, presenting both graphic and textual information. Reports are delivered to all staff working in the four LTC facilities. The primary evaluation uses a controlled interrupted time series design both adjusted and unadjusted for covariates. The concurrent process evaluation uses observation and self-report to assess uptake of the feedback reports. Following the project phase described in this protocol, a similar intervention will be conducted in home care settings in Alberta. Depending on project findings, if they are judged useful by decision makers participating in this research team, we plan dissemination and spread of the feedback report approach throughout Alberta.

The impact of social networks on knowledge transfer in long-term care facilities: Protocol for a study

BACKGROUND

Social networks are theorized as significant influences in the innovation adoption and behavior change processes. Our understanding of how social networks operate within healthcare settings is limited. As a result, our ability to design optimal interventions that employ social networks as a method of fostering planned behavior change is also limited. Through this proposed project, we expect to contribute new knowledge about factors influencing uptake of knowledge translation interventions.

OBJECTIVES

Our specific aims include: To collect social network data among staff in two long-term care (LTC) facilities; to characterize social networks in these units; and to describe how social networks influence uptake and use of feedback reports.

METHODS AND DESIGN

In this prospective study, we will collect data on social networks in nursing units in two LTC facilities, and use social network analysis techniques to characterize and describe the networks. These data will be combined with data from a funded project to explore the impact of social networks on uptake and use of feedback reports. In this parent study, feedback reports using standardized resident assessment data are distributed on a monthly basis. Surveys are administered to assess report uptake. In the proposed project, we will collect data on social networks, analyzing the data using graphical and quantitative techniques. We will combine the social network data with survey data to assess the influence of social networks on uptake of feedback reports.

DISCUSSION

This study will contribute to understanding mechanisms for knowledge sharing among staff on units to permit more efficient and effective intervention design. A growing number of studies in the social network literature suggest that social networks can be studied not only as influences on knowledge translation, but also as possible mechanisms for fostering knowledge translation. This study will contribute to building theory to design such interventions.

Translating health care-associated urinary tract infection prevention research into practice via the bladder bundle

BACKGROUND

Catheter-associated urinary tract infection (CAUTI), a frequent health care-associated infection (HAI), is a costly and common condition resulting in patient discomfort, activity restriction, and hospital discharge delays. The Centers for Medicare & Medicaid Services (CMS) no longer reimburses hospitals for the extra cost of caring for patients who develop CAUTI. The Michigan Health and Hospital Association (MHA) Keystone Center for Patient Safety & Quality has initiated a statewide initiative, MHA Keystone HAI, to help ameliorate the burden of disease associated with indwelling catheterization. In addition, a long-term research project is being conducted to evaluate the current initiative and to identify practical strategies to ensure the effective use of proven infection prevention and patient safety practices.

OVERVIEW OF THE BLADDER BUNDLE INITIATIVE IN MICHIGAN

The bladder bundle as conceived by MHA Keystone HAI focuses on preventing CAUTI by optimizing the use of urinary catheters with a specific emphasis on continual assessment and catheter removal as soon as possible, especially for patients without a clear indication. COLLABORATION BETWEEN RESEARChERS AND STATE WIDE PATIENT SAFETY ORGANIZATIONS: A synergistic collaboration between patient safety researchers and a statewide patient safety organization is aimed at identifying effective strategies to move evidence from peer-reviewed literature to the bedside. Practical strategies that facilitate implementation of the bundle will be developed and tested using mixed quantitative and qualitative methods.

DISCUSSION

Simply disseminating scientific evidence is often ineffective in changing clinical practice. Therefore, learning how to implement these findings is critically important to promoting high-quality care and a safe health care environment.

Line authority for nurse staffing and costs for acute inpatient care

There is little empirical evidence evaluating the effects of recent, widespread changes in nurse executive roles and nursing management structures on the costs of patient care. This retrospective cross-sectional study examined the relationship between line authority for nurse staffing and patient care costs (total, nursing, and non-nursing cost) using data from 124 Department of Veterans Affairs (VA) medical centers. After controlling for patient, facility, and market characteristics, nursing line authority was significantly associated with lower nursing cost per admission. Our results provide some evidence that a reduction in nursing line authority may adversely impact nursing costs.

Public reporting of nursing home quality of care: lessons from the United States experience for canadian policy discussion

While the demand for continuing care services in Canada grows, the quality of such services has come under increasing scrutiny. Consideration has been given to the use of public reporting of quality data as a mechanism to stimulate quality improvement and promote public accountability for and transparency in service quality. The recent adoption of the Resident Assessment Instrument (RAI) throughout a number of Canadian jurisdictions means that standardized quality data are available for comparisons among facilities across regions, provinces and nationally. In this paper, we explore current knowledge on public reporting in nursing homes in the United States to identify what lessons may inform policy discussion regarding potential use of public reporting in Canada. Based on these findings, we make recommendations regarding how public reporting should be progressed and managed if Canadian jurisdictions were to implement this strategy.

Declining mortality following acute myocardial infarction in the Department of Veterans Affairs Health Care System

BACKGROUND

Mortality from acute myocardial infarction (AMI) is declining worldwide. We sought to determine if mortality in the Veterans Health Administration (VHA) has also been declining.

METHODS

We calculated 30-day mortality rates between 2004 and 2006 using data from the VHA External Peer Review Program (EPRP), which entails detailed abstraction of records of all patients with AMI. To compare trends within VHA with other systems of care, we estimated relative mortality rates between 2000 and 2005 for all males 65 years and older with a primary diagnosis of AMI using administrative data from the VHA Patient Treatment File and the Medicare Provider Analysis and Review (MedPAR) files.

RESULTS

Using EPRP data on 11,609 patients, we observed a statistically significant decline in adjusted 30-day mortality following AMI in VHA from 16.3% in 2004 to 13.9% in 2006, a relative decrease of 15% and a decrease in the odds of dying of 10% per year (p = .011). Similar declines were found for in-hospital and 90-day mortality.Based on administrative data on 27,494 VHA patients age 65 years and older and 789,400 Medicare patients, 30-day mortality following AMI declined from 16.0% during 2000-2001 to 15.7% during 2004-June 2005 in VHA and from 16.7% to 15.5% in private sector hospitals. After adjusting for patient characteristics and hospital effects, the overall relative odds of death were similar for VHA and Medicare (odds ratio 1.02, 95% C.I. 0.96-1.08).

CONCLUSION

Mortality following AMI within VHA has declined significantly since 2003 at a rate that parallels that in Medicare-funded hospitals.

Organizational readiness to change assessment (ORCA): development of an instrument based on the Promoting Action on Research in Health Services (PARIHS) framework

BACKGROUND

The Promoting Action on Research Implementation in Health Services, or PARIHS, framework is a theoretical framework widely promoted as a guide to implement evidence-based clinical practices. However, it has as yet no pool of validated measurement instruments that operationalize the constructs defined in the framework. The present article introduces an Organizational Readiness to Change Assessment instrument (ORCA), organized according to the core elements and sub-elements of the PARIHS framework, and reports on initial validation.

METHODS

We conducted scale reliability and factor analyses on cross-sectional, secondary data from three quality improvement projects (n = 80) conducted in the Veterans Health Administration. In each project, identical 77-item ORCA instruments were administered to one or more staff from each facility involved in quality improvement projects. Items were organized into 19 subscales and three primary scales corresponding to the core elements of the PARIHS framework: (1) Strength and extent of evidence for the clinical practice changes represented by the QI program, assessed with four subscales, (2) Quality of the organizational context for the QI program, assessed with six subscales, and (3) Capacity for internal facilitation of the QI program, assessed with nine subscales.

RESULTS

Cronbach's alpha for scale reliability were 0.74, 0.85 and 0.95 for the evidence, context and facilitation scales, respectively. The evidence scale and its three constituent subscales failed to meet the conventional threshold of 0.80 for reliability, and three individual items were eliminated from evidence subscales following reliability testing. In exploratory factor analysis, three factors were retained. Seven of the nine facilitation subscales loaded onto the first factor; five of the six context subscales loaded onto the second factor; and the three evidence subscales loaded on the third factor. Two subscales failed to load significantly on any factor. One measured resources in general (from the context scale), and one clinical champion role (from the facilitation scale).

CONCLUSION

We find general support for the reliability and factor structure of the ORCA. However, there was poor reliability among measures of evidence, and factor analysis results for measures of general resources and clinical champion role did not conform to the PARIHS framework. Additional validation is needed, including criterion validation.

The feasibility of Web-based surveys as a data collection tool: a process evaluation

This study used a cross-sectional survey design with a concurrent process evaluation to examine the feasibility of using Web surveys in a population of acute care neonatal and pediatric nurses. The purpose of conducting a process evaluation was to understand if using strategies such as maximizing face-to-face communication with participants, sending reminder notices, and providing continuous support would encourage nurses to use a Web-based survey. In addition, we sought feedback about where nurses completed the survey, the number of sittings and length of time it took, and why participants that selected the print mode chose not to use the Web.

Improving care to patients with ischemic heart disease: experiences in a single network of the Veterans Health Administration

BACKGROUND

Ischemic heart disease (IHD) is the leading cause of death in the United States. Lowering serum cholesterol levels reduces coronary events and mortality; this effect is most evident in patients with preexisting IHD.

AIMS

The primary aim of this article is to describe a set of interventions that were piloted in a single, regional Veterans Integrated Service Network (VISN) to promote secondary prevention among patients with IHD and to explore the effect of those interventions on patient outcomes.

METHODS

An observational, before-and-after study of clinical interventions to improve lipid guideline compliance in VISN 20 (the Veterans Administration Northwest Network) was conducted. A total of 2,467 patients with established coronary artery disease from three medical facilities in VISN 20 were included. Each medical facility chose different interventions to lower low-density lipoprotein cholesterol (LDL-c) levels in their patients. One facility chose a paper point-of-care reminder, a second chose a lipid clinic, and a third chose audit/feedback to clinicians in addition to a patient-education component. Data came from a relational database that mirrors the clinical information system at each site. Outcomes included the proportion of patients who had their LDL-c measured, the proportion of patients who had lipid-lowering agents prescribed, and the proportion of patients at LDL-c goal of lower than 100 mg/dL measured before, during, and after the intervention period.

RESULTS

Statistically significant improvements were observed within sites after the interventions were implemented.

IMPLICATIONS FOR PRACTICE

Interventions that focused on secondary prevention in this high-risk group were moderately successful in changing practice. Tailoring interventions to the needs of a specific site of care is feasible and may add to the likelihood of succeeding.

CONCLUSION

Overall, the three facilities improved in lipid measurement and management for patients with coronary artery disease.

A qualitative study to identify barriers and facilitators to implementation of pilot interventions in the Veterans Health Administration (VHA) Northwest Network

OBJECTIVE

To identify barriers and facilitators to implementation of pilot interventions designed to improve measurement and management of low-density lipoprotein cholesterol (LDL-c) levels in coronary heart disease patients using the evidence/context/facilitation model of implementation of evidence-based practice.

DESIGN

Theory-based conceptual content analysis of structured interviews conducted between January and April 2001.

SETTING

Six medical centers in the United States Veterans Health Administration Northwest Network.

PARTICIPANTS

Fifty-one of 64 individuals (physicians, nurses, pharmacists, dieticians, quality managers, and other clinical and nonclinical staff) who participated in planning and/or implementing pilot interventions.

MAIN FINDINGS

Barriers to successful implementation related primarily to the intervention process and secondarily to characteristics of the intervention context. Interview responses indicated that planning, including identification of resources and assessment of potential barriers and facilitators, was a critical and universally underutilized step in the intervention process.

CONCLUSIONS

Organized team process, documented plans for intervention activities, and ongoing evaluation are essential for sustaining intervention activities. A top priority for facilitating interventions should be the development of educational materials, such as "how to" guides, that teach intervention teams how to anticipate barriers and make plans to address them, as well as identifying and fostering local experts in planning and implementing interventions.

Inpatient and follow-up cardiology care and mortality for acute coronary syndrome patients in the Veterans Health Administration

BACKGROUND

The impact of inpatient and follow-up cardiology care on patient outcomes after acute coronary syndrome (ACS) hospital discharge is unknown.

METHODS

This was a retrospective cohort study of all patients with ACS discharged from Veterans Health Administration facilities from 2003 to 2004. Patients were stratified into 2 categories of cardiology care: (1) inpatient and follow-up cardiology care within 60 days after discharge and (2) other levels of cardiology care (inpatient only, outpatient only, and neither inpatient nor outpatient). Multivariable regression assessed the association between inpatient and follow-up cardiology care with all-cause mortality, adjusting for demographics, comorbidities, hospital presentation and treatment variables, and clustering by site.

RESULTS

Of 4933 patients with ACS, the majority (71.6%) had inpatient and follow-up cardiology care. Patients with inpatient and follow-up cardiology care were more likely to have prior coronary disease and diabetes and to present with myocardial infarction (vs unstable angina). All-cause mortality was lower for patients with inpatient and follow-up cardiology care (18.8% vs 22.1%, P = .009). In multivariable analysis, patients with inpatient and follow-up cardiology care remained at lower mortality risk (hazard ratio 0.73, 95% CI 0.62-0.87) compared with patients with other levels of cardiology care. The findings were consistent when cardiology follow-up was defined as 30 or 90 days after hospital discharge.

CONCLUSIONS

Patients with inpatient and follow-up cardiology care have lower mortality risk after ACS. Future studies should identify mediators of this potential benefit and determine if interventions enhancing continuity of care in general, and continuity of subspecialty care in particular, after ACS will improve patient outcomes.

A view from health services research and outcomes measurement

Depicted in this presentation is the relationship of the aims of the original articles in this issue--using theory in a substantive way; introducing a strong focus on the organization as a contributor to patient, provider, and system outcomes; accounting for organizational level; and moving the field toward a view of research utilization as an intermediate, not terminal, outcome--to outcomes research in health services generally and in nursing health services research more specifically. The insights and innovations described in this set of articles contribute significantly to the literature on research use in healthcare, specifically including the need to account more fully for organizational structure and hierarchy than has been the case to date in health services outcomes research, as well as a strong intimation that research use is not only an important intervening variable in the causal chain producing outcomes at the patient, provider, and system levels but also a latent or unobservable variable.

Pre-pregnancy body mass index, gestational weight gain, and other maternal characteristics in relation to infant birth weight

OBJECTIVES

Infant birth weight is influenced by modifiable maternal pre-pregnancy behaviors and characteristics. We evaluated the relationship among pre-pregnancy body mass index (BMI), gestational weight gain, and infant birth weight, in a prospective cohort study.

METHODS

Women were enrolled at < or =20 weeks gestation, completed in-person interviews and had their medical records reviewed after delivery. Infant birth weight was first analyzed as a continuous variable, and then grouped into Low birth weight (LBW) (<2,500 g), normal birth weight (2,500-3,999 g), and macrosomia (> or =4,000 g) in categorical analysis. Pre-pregnancy BMI and gestational weight gain were categorized based on Institute of Medicine BMI groups and gestational weight gain guidelines. Associations among infant birth weight and pre-pregnancy BMI, gestational weight gain, and other factors were evaluated using multivariate regression. Risk ratios were estimated using generalized linear modeling procedures.

RESULTS

Pre-pregnancy BMI was independently and positively associated with infant birth weight (beta = 44.7, P = 0.001) after adjusting for confounders, in a quadratic model. Gestational weight gain was positively associated with infant birth weight (beta = 19.5, P < 0.001). Lower infant birth weight was associated with preterm birth (beta = -965.4, P < 0.001), nulliparity (beta = -48.6, P = 0.015), and female babies (beta = -168.7, P < 0.001). Less than median gestational weight gain was associated with twice the risk of LBW (RR = 2.04, 95% CI 1.34-3.11). Risk of macrosomia increased with increasing pre-pregnancy BMI and gestational weight gain (P for linear trend <0.001).

CONCLUSIONS

These findings support the need to balance pre-pregnancy weight and gestational weight gain against the risk of LBW and macrosomia among lean and obese women, respectively.

Assessing an organizational culture instrument based on the Competing Values Framework: exploratory and confirmatory factor analyses

Background

The Competing Values Framework (CVF) has been widely used in health services research to assess organizational culture as a predictor of quality improvement implementation, employee and patient satisfaction, and team functioning, among other outcomes. CVF instruments generally are presented as well-validated with reliable aggregated subscales. However, only one study in the health sector has been conducted for the express purpose of validation, and that study population was limited to hospital managers from a single geographic locale.

Methods

We used exploratory and confirmatory factor analyses to examine the underlying structure of data from a CVF instrument. We analyzed cross-sectional data from a work environment survey conducted in the Veterans Health Administration (VHA). The study population comprised all staff in non-supervisory positions. The survey included 14 items adapted from a popular CVF instrument, which measures organizational culture according to four subscales: hierarchical, entrepreneurial, team, and rational.

Results

Data from 71,776 non-supervisory employees (approximate response rate 51%) from 168 VHA facilities were used in this analysis. Internal consistency of the subscales was moderate to strong (α = 0.68 to 0.85). However, the entrepreneurial, team, and rational subscales had higher correlations across subscales than within, indicating poor divergent properties. Exploratory factor analysis revealed two factors, comprising the ten items from the entrepreneurial, team, and rational subscales loading on the first factor, and two items from the hierarchical subscale loading on the second factor, along with one item from the rational subscale that cross-loaded on both factors. Results from confirmatory factor analysis suggested that the two-subscale solution provides a more parsimonious fit to the data as compared to the original four-subscale model.

Conclusion

This study suggests that there may be problems applying conventional CVF subscales to non-supervisors, and underscores the importance of assessing psychometric properties of instruments in each new context and population to which they are applied. It also further highlights the challenges management scholars face in assessing organizational culture in a reliable and comparable way. More research is needed to determine if the emergent two-subscale solution is a valid or meaningful alternative and whether these findings generalize beyond VHA.

Measuring nurses' practice environments with the revised nursing work index: evidence from registered nurses in the Veterans Health Administration

The Revised Nursing Work Index (NWI-R) is a widely used instrument for evaluating registered nurses' (RNs) practice environments. The existence of multiple subscale sets from the NWI-R raises questions about its generalizability. We tested the validity of the one-, three-, and five-subscale sets from the NWI-R and derived a short-form subscale set using a sample of RNs from the Veterans Health Administration (VHA). The prior sets do not have an excellent fit to these data. Results of exploratory factor analyses suggested a four-factor model with Opportunity for Advancement, Collegial Nurse-Physician Relations, Staffing Adequacy, and Nurse Manager Leadership as the most salient and parsimonious solution. Additional research is needed to corroborate these findings in other nurse samples and settings.

Nurse Executive and Staff Nurse Perceptions of the Effects of Reorganization in Veterans Health Administration Hospitals

OBJECTIVE

To examine nurse executive perceptions of effects of service line reorganization on nurse executive roles, nursing staff and patient care, and compare nurse executive responses to staff nurse reports of job satisfaction and quality of care in the same types of Veterans Health Administration facilities.

BACKGROUND

Although a growing body of research focuses on the association between nurse staffing structures, nurse satisfaction, and patient outcomes, relatively little attention has been paid to the effects of hospital restructuring on nursing management and nursing staff.

METHODS

Data on hospital and nursing service organization and nurse executive perceptions were collected through structured interviews with 125 nurse executives conducted from December 2002 through May 2003. Staff nurse data were derived from a survey of Veterans Health Administration nursing staff conducted from February through June 2003 at the same facilities.

RESULTS

Nurse executives in Veterans Health Administration described significant changes in the nurse executive role, and new challenges for managing nursing practice and achieving consistent quality of nursing care. Although nursing management perceived differences in the overall effects of restructuring on nursing staff depending on the type of reorganization, staff nurses reported significant differences in perceived quality of patient care across organization types.

The use of percutaneous coronary intervention in black and white veterans with acute myocardial infarction

BACKGROUND

It is uncertain whether black white differences in the use of percutaneous coronary intervention (PCI) persist in the era of drug eluting stents. The purpose of this study is to determine if black veterans with acute myocardial infarction (AMI) are less likely to receive PCI than their white counterparts.

METHODS

This study included 680 black and 3529 white veterans who were admitted to Veterans Health Administration (VHA) medical centers between July 2003 and August 2004. Information for this study was collected as part of the VHA External Peer Review Program for quality monitoring and improvement for a variety of medical conditions and procedures, including AMI. In addition, Department of Veterans Affairs workload files were used to determine PCI utilization after hospital discharge. Standard statistical methods including the Chi-square, 2 sample t-test, and logistic regression with a cluster correction for medical center were used to assess the association between race and the use of PCI < or = 30 days from admission.

RESULTS

Black patients were younger, more often had diabetes mellitus, renal disease, or dementia and less often had lipid disorders, previous coronary artery bypass surgery, or chronic obstructive pulmonary disease than their white counterparts. Equal proportions of blacks and whites underwent cardiac catheterization < or = 30 days after admission, but the former were less likely to undergo PCI (32% vs. 40%, p < 0.0001). This difference persisted after multivariate adjustment, although measures of the extent of coronary artery disease were not available.

CONCLUSION

Given the equivalent use of cardiac catheterization, it is possible that less extensive or minimal coronary artery disease in black patients could account for the observed difference.

Racial and ethnic differences in diabetes care and health care use and costs

INTRODUCTION

Previous studies have shown racial and ethnic differences in diabetes complication rates and diabetes control. The objective of this study was to examine racial and ethnic differences in diabetes care and health care use and costs for adults with diabetes using a nationally representative sample of the U.S. noninstitutionalized civilian population.

METHODS

We performed a cross-sectional analysis of the 2000 Medical Expenditure Panel Survey (MEPS) and its related Diabetes Care Survey. The respondents were adults (aged 18 years and older) with diabetes, including non-Hispanic whites, non-Hispanic African Americans, and Hispanics. Racial and ethnic differences were examined in diabetes process of care and health care use and costs using logistic regression, negative binomial regression, and ordinary least squares regression with log cost.

RESULTS

Most of the outcomes in diabetes care management, treatment, and complications were not significantly different among race groups. After adjusting for socioeconomic and demographic characteristics, Hispanics were more likely to have eye problems than whites (odds ratio, 1.56; 95% confidence interval, 1.03-2.56). African Americans and Hispanics had lower total health care costs, lower ambulatory care costs, and lower prescription drug costs than whites (P < .01 for all).

CONCLUSION

We found differences in ambulatory care and prescription drug fills among white, African American, and Hispanic adults with diabetes. However, most of the diabetes care measures were not significantly different among the three racial and ethnic groups. Understanding the reason outcomes do not differ when health care use and costs differ significantly should be a focus of future studies.

The association between processes, structures and outcomes of secondary prevention care among VA ischemic heart disease patients

Background

Hyperlipidemia and hypertension are well-established risk factors for recurrent cardiovascular events among patients with ischemic heart disease (IHD). Despite national recommendations, concordance with guidelines for LDL cholesterol and blood pressure remains inadequate. The objectives of this study were to 1) determine concordance rates with LDL cholesterol and BP recommendations; and 2) identify patient factors, processes and structures of care associated with guideline concordance among VA IHD patients.

Methods

This was a cross sectional study of veterans with IHD from 8 VA hospitals. Outcomes were concordance with LDL guideline recommendations (LDL<100 mg/dl), and BP recommendations (<140/90 mm Hg). Cumulative logit and hierarchical logistic regression analyses were performed to identify patient factors, processes, and structures of care independently associated with guideline concordance.

Results

Of 14,114 veterans with IHD, 55.7% had hypertension, 71.5% had hyperlipidemia, and 41.6% had both conditions. Guideline concordance for LDL and BP were 38.9% and 53.4%, respectively. However, only 21.9% of the patients achieved both LDL <100 mg/dl and BP <140/90 mm Hg. In multivariable analyses, patient factors including older age and the presence of vascular disease were associated with worse guideline concordance. In contrast, diabetes was associated with better guideline concordance. Several process of care variables, including higher number of outpatient visits, higher number of prescribed medications, and a recent cardiac hospitalization were associated with better guideline concordance. Among structures of care, having on-site cardiology was associated with a trend towards better guideline concordance.

Conclusion

Guideline concordance with secondary prevention measures among IHD patients remains suboptimal. It is hoped that the findings of this study can serve as an impetus for quality improvement efforts to improve upon secondary prevention measures and reduce the morbidity and mortality of patients with known IHD.

Lessons learned about implementing research evidence into clinical practice. Experiences from VA QUERI

The mission of the Veterans Health Administration's (VHA) quality enhancement research initiative (QUERI) is to enhance the quality of VHA health care by implementing clinical research findings into routine care. This paper presents lessons that QUERI investigators have learned through their initial attempts to pursue the QUERI mission. The lessons in this paper represent those that were common across multiple QUERI projects and were mutually agreed on as having substantial impact on the success of implementation. While the lessons are consistent with commonly recognized ingredients of successful implementation efforts, the examples highlight the fact that, even with a thorough knowledge of the literature and thoughtful planning, unexpected circumstances arise during implementation efforts that require flexibility and adaptability. The findings stress the importance of utilizing formative evaluation techniques to identify barriers to successful implementation and strategies to address these barriers.

Outcomes after acute coronary syndrome admission to primary versus tertiary Veterans Affairs medical centers: the Veterans Affairs Access to Cardiology study

BACKGROUND

There is a concern that patients with acute coronary syndrome (ACS) admitted to primary care hospitals (without on-site cardiac procedures) may be at risk for worse outcomes compared with patients admitted to tertiary care hospitals. In addition to mortality, one way to assess patient outcomes is via health status and rehospitalization rates. We compared the health status and rehospitalization of patients with ACS admitted to primary versus tertiary care Veterans Affairs hospitals.

METHODS

This was a cohort study of 2132 patients with ACS admitted to 21 Veterans Affairs hospitals (12 primary care and 9 tertiary care) from 1998 to 1999. Primary outcomes were 7-month health status as measured by the Seattle Angina Questionnaire and rehospitalization. Hierarchical multivariable regression was used to evaluate the association between admission to a primary (vs tertiary) care hospital and these outcomes. Discharge medications and 7-month cardiac procedure rates were also compared.

RESULTS

There were no significant differences in discharge medication rates between primary and tertiary hospital patients. Forty-two percent of the patients admitted to a primary care hospital was transferred to a tertiary care hospital during index admission. Primary hospital patients had significantly lower 7-month rates of cardiac catheterization (36% vs 51%, P < .001) and percutaneous coronary intervention (11% vs 20%, P < .001), but there were no differences in coronary artery bypass graft surgery rates. After risk adjustment, there were no significant differences in 7-month angina frequency (odds ratio [OR] 0.98, 95% CI 0.78-1.22), physical limitation (OR 0.97, 95% CI 0.77-1.23), quality of life (OR 1.12, 95% CI 0.89-1.40), or rehospitalization (OR 1.07, 95% CI 0.54-2.14) between the 2 groups.

CONCLUSIONS

These results suggest that an integrated health care system can achieve similar intermediate-term health status and rehospitalization outcomes for patients with ACS irrespective of the site of admission despite the lower rates of cardiac procedures for the primary care hospital patients.

Nurse Staffing and Patient Outcomes in Veterans Affairs Hospitals

OBJECTIVE

To assess characteristics and perceptions of nurses working in the Veterans Health Administration (VHA), comparing types of nursing personnel, to benchmark to prior studies across healthcare systems.

BACKGROUND

Prior studies have shown relationships between positive registered nurse (RN) perceptions of the practice environment and patient outcomes. To date, no study has reported the comparison of RN perceptions of the practice environment in hospital nursing with those of non-RN nursing personnel. This study is the first to offer a more comprehensive look at perceptions of practice environment from the full range of the nursing work force and may shed light on issues such as the relationship of skill mix to nurse and patient outcomes.

METHODS

Cross-sectional observational study with a mailed survey administered to all nursing personnel in 125 VA Medical Centers between February and June 2003.

RESULTS

Compared with other types of nursing personnel in the VHA, RNs are generally less positive about their practice environments. However, compared with RNs in other countries and particularly with other RNs in the United States (Pennsylvania), VHA RNs are generally more positive about their practice environment and express more job satisfaction.

CONCLUSIONS

The nursing work force of the VHA has some unique characteristics. The practice environment for nurses in the VHA is relatively positive, and may indicate that the VHA, as a system, provides an environment that is more like magnet hospitals. This is significant for a public sector hospital system.

Utilization of drug-eluting stents in the Veterans Health Administration

Little is known about how drug-eluting stents (DESs) are used and perform in everyday clinical practice. This report identifies factors associated with the use of DESs in the Veterans Health Administration and compares mortality and the need for coronary artery bypass graft surgery in patients who received DESs or bare metal stents. There was rapid adoption of DESs from the end of 2002 to September 2004, when 52% of percutaneous coronary interventions used DESs. Ten-day death rates in DES and bare metal stent groups were similar (0.8% vs 1.1%), as were 10-day bypass surgery rates (0.2% vs 0.4%). In summary, in a large health care system, DESs were used widely with low rates of death and bypass surgery.

Adherence to heart-healthy behaviors in a sample of the U.S. population

INTRODUCTION

Following national recommendations for physical activity, diet, and nonsmoking can reduce both incident and recurrent coronary heart disease. Prevalence data about combinations of behaviors are lacking. This study describes the prevalence of full adherence to national recommendations for physical activity, fruit and vegetable consumption, and nonsmoking among individuals with and without coronary heart disease and examines characteristics associated with full adherence.

METHODS

We performed a cross-sectional analysis of data from the 2000 Behavioral Risk Factor Surveillance System, a national population-based survey. We included respondents to the cardiovascular disease module and excluded individuals with poor physical health or activity limitations.

RESULTS

Subjects were most adherent to smoking recommendations (approximately 80%) and less adherent to fruit and vegetable consumption and physical activity (approximately 20% for both). Only 5% of those without coronary heart disease and 7% of those with coronary heart disease were adherent to all three behaviors (P < .01). Among those without a history of coronary heart disease, female sex (odds ratio [OR] 1.47; 95% confidence interval [CI], 1.23-1.76), highest age quintile (OR 1.67; 95% CI, 1.28-2.19), more education (OR 2.48; 95% CI, 1.69-3.64), and more income (OR 1.19; 95% CI, 1.04-1.36) were associated with full adherence. Among those with coronary heart disease, mid-age quintile (OR 3.79; 95% CI, 1.35-10.68), good general health (OR 2.05; 95% CI, 1.07-3.94), and more income (OR 1.51; 95% CI, 1.06-2.16) were associated with full adherence.

CONCLUSION

These data demonstrate the lack of a heart-healthy lifestyle among a sample of U.S. adults with and without coronary heart disease. Full adherence to combined behaviors is far below adherence to any of the individual behaviors.
