Changes in perceptions of antibiotic stewardship among neonatal intensive care unit providers over the course of a learning collaborative: a prospective, multisite, mixed-methods evaluation

OBJECTIVE

To assess clinician perceptions towards the value and implementation of antibiotic stewardship (AS) in neonatal intensive care units (NICU).

STUDY DESIGN

We performed a mixed-methods study of AS perceptions (prescribing appropriateness, importance, activity, capacity) using surveys and interviews in 30 California NICUs before and after a multicenter collaborative (Optimizing Antibiotic Use in California NICUs [OASCN]).

RESULTS

Pre-OASCN, 24% of respondents felt there was "a lot of" or "some" inappropriate prescribing, often driven by fear of a bad outcome or reluctance to change existing practice. Clinicians reported statistically significant increases in AS importance (71 v 79%), perceived AS activity (67 v 87%), and more openness to change after OASCN (59 v 70%). We identified other concerns that lessen AS effort.

CONCLUSION

OASCN increased perceived AS activity and openness to change in AS practices among NICU prescribers. Greater attention to subjective concerns should augment AS improvement.

A cross-stakeholder approach to improving out-of-hospital cardiac arrest survival

BACKGROUND

Out-of-hospital cardiac arrest (OHCA) affects over 300,000 individuals per year in the United States with poor survival rates overall. A remarkable 5-fold difference in survival-to-hospital discharge rates exist across United States communities.

METHODS

We conducted a study using qualitative research methods comparing the system of care across sites in Michigan communities with varying OHCA survival outcomes, as measured by return to spontaneous circulation with pulse upon emergency department arrival.

RESULTS

Major themes distinguishing higher performing sites were (1) working as a team, (2) devoting resources to coordination across agencies, and (3) developing a continuous quality improvement culture. These themes spanned the chain of survival framework for OHCA. By examining the unique processes, procedures, and characteristics of higher- relative to lower-performing sites, we gleaned lessons learned that appear to distinguish higher performers. The higher performing sites reported being the most collaborative, due in part to facilitation of system integration by progressive leadership that is willing to build bridges among stakeholders.

CONCLUSIONS

Based on the distinguishing features of higher performing sites, we provide recommendations for toolkit development to improve survival in prehospital systems of care for OHCA.

Blood culture procedures and practices in the neonatal intensive care unit: A survey of a large multicenter collaborative in California

OBJECTIVE

To describe variation in blood culture practices in the neonatal intensive care unit (NICU).

DESIGN

Survey of neonatal practitioners involved with blood culturing and NICU-level policy development.

PARTICIPANTS

We included 28 NICUs in a large antimicrobial stewardship quality improvement program through the California Perinatal Quality Care Collaborative.

METHODS

Web-based survey of bedside blood culture practices and NICU- and laboratory-level practices. We evaluated adherence to recommended practices.

RESULTS

Most NICUs did not have a procedural competency (54%), did not document the sample volume (75%), did not receive a culture contamination report (57%), and/or did not require reporting to the provider if <1 mL blood was obtained (64%). The skin asepsis procedure varied across NICUs. Only 71% had a written procedure, but ≥86% changed the needle and disinfected the bottle top prior to inoculation. More than one-fifth of NICUs draw a culture from an intravascular device only (if present). Of 13 modifiable practices related to culture and contamination, NICUs with nurse practitioners more frequently adopted >50% of practices, compared to units without (92% vs 50% of units; P < .02).

CONCLUSIONS

In the NICU setting, recommended practices for blood culturing were not routinely performed.

Strategies for Enhancing Prehospital Outcomes for Cardiac Arrest (EPOC)

Out-of-hospital cardiac arrest (OHCA) is a common, life-threatening event that is a leading cause of death in the United States. However, it is unclear how to design strategies that can be successfully implemented in emergency medical services (EMS) agencies and broader emergency response systems (such as fire, police, dispatch, and bystanders to OHCA events) in different communities to help improve daily care processes and outcomes in OHCA. The National Heart, Lung, and Blood Institute-funded Enhancing Prehospital Outcomes for Cardiac Arrest (EPOC) study lays the foundation for future quality improvement efforts in OHCA by identifying, understanding, and validating the best practices adopted within emergency response systems to address these life-threatening events and by addressing potential barriers to implementation of these practices. RAND researchers developed recommendations covering all levels of the prehospital OHCA incident response and the principles of change management necessary to implement those recommendations.

Standardized Versus Tailored Implementation of Measurement-Based Care for Depression in Community Mental Health Clinics

Objective

Measurement-based care (MBC) is an evidence-based practice that is rarely integrated into psychotherapy. The authors sought to determine whether tailored MBC implementation can improve clinician fidelity and depression outcomes compared with standardized implementation.

Methods

This cluster-randomized trial enrolled 12 community behavioral health clinics to receive 5 months of implementation support. Clinics randomized to the standardized implementation received electronic health record data captured with the nine-item Patient Health Questionnaire (PHQ-9), a needs assessment, clinical training, guidelines, and group consultation in MBC fidelity. Tailored implementation support included these strategies, but the training content was tailored to clinics’ barriers to MBC, and group consultation centered on overcoming these barriers. Clinicians (N=83, tailored; N=71, standardized) delivering individual psychotherapy to 4,025 adults participated. Adult patients (N=87, tailored; N=141, standardized) contributed data for depression outcome analyses.

Results

The odds of PHQ-9 completion were lower in the tailored group at baseline (odds ratio [OR]=0.28, 95% CI=0.08–0.96) but greater at 5 months (OR=3.39, 95% CI=1.00–11.48). The two implementation groups did not differ in full MBC fidelity. PHQ-9 scores decreased significantly from baseline (mean±SD=17.6±4.4) to 12 weeks (mean=12.6±5.9) (p<0.001), but neither implementation group nor MBC fidelity significantly predicted PHQ-9 scores at week 12.

Conclusions

Tailored MBC implementation outperformed standardized implementation with respect to PHQ-9 completion, but discussion of PHQ-9 scores in clinician-patient sessions remained suboptimal. MBC fidelity did not predict week-12 depression severity. MBC can critically inform collaborative adjustments to session or treatment plans, but more strategic system-level implementation support or longer implementation periods may be needed.

A Process Evaluation of Primary Care Behavioral Health Integration in the Military Health System

Behavioral health (BH) problems are common in the military and can adversely affect force readiness. Research suggests that primary care-behavioral health (PCBH) integration can improve BH outcomes by making high-quality BH care available in more accessible settings. However, sustaining high-quality implementation of PCBH is challenging. The authors conducted a process evaluation of the PCBH program in the military health system to understand why the program is working as it is and provide recommendations for quality improvement. They conducted semistructured interviews, rigorously coded the qualitative data to identify causal links, and created and validated causal loop diagrams that provide a visualization of how the system is working. Findings fall into four key areas: staffing and capabilities, valued tasks, program stewardship, and fostering program awareness and support. Overall, the authors found that the PCBH program is highly valued by primary care staff. However, the PCBH care model is inconsistently adhered to, owing to a combination of staff preferences, local pressures, and lack of knowledge of PCBH staff roles. Recommendations are offered to improve program implementation.

Health Services and Primary Care Research Study: Comprehensive Report

This study presents the results of a congressionally mandated, independent assessment of federally funded health services research (HSR) and primary care research (PCR) spanning the U.S. Department of Health and Human Services (HHS) and U.S. Department of Veterans Affairs (VA) from FYs 2012 to 2018. Through technical expert panels, stakeholder interviews, and a systematic environmental scan of research grants and contracts funded by HHS and the VA, the authors characterize the distinct contributions of agencies in these departments to the federal HSR and PCR enterprise. The authors also identify opportunities to improve detection and coordination of overlap in agency research portfolios, the impacts of HSR and PCR and how they cumulate across research portfolios, and gaps in research funding, methods, and dissemination. The authors offer recommendations to maximize the outcomes and value of future investments in federal HSR and PCR to better guide and serve the needs of a complex and rapidly changing U.S. health care system.

The Association of Fire or Police First Responder Initiated Interventions with Out of Hospital Cardiac Arrest Survival

OBJECTIVE

Fire and police first responders are often the first to arrive in medical emergencies and provide basic life support services until specialized personnel arrive. This study aims to evaluate rates of fire or police first responder-initiated cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) use, as well as their associated impact on out-of-hospital cardiac arrest (OHCA) outcomes.

METHODS

We completed a secondary data analysis of the MI-CARES registry from 2014 to 2019. We reported rates of CPR initiation and AED use by fire or police first responders. Multilevel modeling was utilized to evaluate the relationship between fire/police first responder-initiated interventions and outcomes of interest: ROSC upon emergency department arrival, survival to hospital discharge, and good neurologic outcome.

RESULTS

Our cohort included 25,067 OHCA incidents. We found fire or police first responders initiated CPR in 31.8% of OHCA events and AED use in 6.1% of OHCA events. Likelihood of sustained ROSC on ED arrival after CPR initiated by a fire/police first responder was not statistically different as compared to EMS initiated CPR (aOR 1.01, CI 0.93-1.11). However, fire/police first responder interventions were associated with significantly higher odds of survival to hospital discharge and survival with good neurologic outcome (aOR 1.25, 95% CI 1.08-1.45 and aOR 1.40, 95% CI 1.18-1.65, respectively). Similar associations were see when examining fire or police initiated AED use.

CONCLUSIONS

Fire or police first responders may be an underutilized, potentially powerful mechanism for improving OHCA survival. Future studies should investigate barriers and opportunities for increasing first responder interventions by these groups in OHCA.

Engaging Community Networks to Improve Depression Services: A Cluster-Randomized Trial of a Community Engagement and Planning Intervention

This paper explores the effects of a group-randomized controlled trial, Community Partners in Care (CPIC), on the development of interagency networks for collaborative depression care improvement between a community engagement and planning (CEP) intervention and a resources for services (RS) intervention that provided the same content solely via technical assistance to individual programs. Both interventions consisted of a diverse set of service agencies, including health, mental health, substance abuse treatment, social services, and community-trusted organizations such as churches and parks and recreation centers. Participants in the community councils for the CEP intervention reflected a range of agency leaders, staff, and other stakeholders. Network analysis of partnerships among agencies in the CEP versus RS condition, and qualitative analysis of perspectives on interagency network changes from multiple sources, suggested that agencies in the CEP intervention exhibited greater growth in partnership capacity among themselves than did RS agencies. CEP participants also viewed the coalition development intervention both as promoting collaboration in depression services and as a meaningful community capacity building activity. These descriptive results help to identify plausible mechanisms of action for the CPIC interventions and can be used to guide development of future community engagement interventions and evaluations in under-resourced communities.

Applying Elinor Ostrom's Design Principles to Guide Co-Design in Health(care) Improvement: A Case Study with Citizens Returning to the Community from Jail in Los Angeles County

INTRODUCTION

Increased interest in collaborative and inclusive approaches to healthcare improvement makes revisiting Elinor Ostrom's 'design principles' for enabling collective management of common pool resources (CPR) in polycentric systems a timely endeavour.

THEORY AND METHOD

Ostrom proposed a generalisable set of eight core design principles for the efficacy of groups. To consider the utility of Ostrom's principles for the planning, delivery, and evaluation of future health(care) improvement we retrospectively apply them to a recent co-design project.

RESULTS

Three distinct aspects of co-design were identified through consideration of the principles. These related to: (1) understanding and mapping the system (2) upholding democratic values and (3) regulating participation. Within these aspects four of Ostrom's eight principles were inherently observed. Consideration of the remaining four principles could have enhanced the systemic impact of the co-design process.

DISCUSSION

Reconceptualising co-design through the lens of CPR offers new insights into the successful system-wide application of such approaches for the purpose of health(care) improvement.

CONCLUSION

The eight design principles - and the relationships between them - form a heuristic that can support the planning, delivery, and evaluation of future healthcare improvement projects adopting co-design. They may help to address questions of how to scale up and embed such approaches as self-sustaining in wider systems.

Do common metrics add value? Perspectives from NIH Clinical and Translational Science Awards (CTSA) Consortium hubs

INTRODUCTION

The Clinical and Translational Science Awards (CTSA) Consortium, a network of academic health care institutions with CTSA hubs, is charged with improving the national clinical and translational research enterprise. The CTSA Consortium and the NIH National Center for Advancing Translational Sciences implemented the Common Metrics Initiative comprised of standardized metrics and a shared performance improvement framework. This article summarizes hubs' perspectives on its value during the initial implementation.

METHODS

The value was assessed across 58 hubs. Survey items assessed change in perceived ability to manage performance and advance clinical and translational science. Semi-structured interviews elicited hubs' perspectives on meaningfulness and value-added of the Common Metrics Initiative and hubs' recommendations.

RESULTS

Hubs considered their abilities to manage performance to have improved, but there was no change in perceived ability to advance clinical and translational science. The initiative added value by providing a formal structured process, enabling strategic conversations, facilitating improvements in processes, providing an external impetus for improvement, and providing justification for funds invested. Hubs were concerned about the usefulness of the metrics chosen and whether the value-added was sufficient relative to the effort required. Hubs recommended useful benchmarking, disseminating best practices and promoting peer-to-peer learning, and expanding the use of data to inform the initiative.

CONCLUSIONS

Implementing Common Metrics and a performance improvement framework yielded concrete short-term benefits, but concerns about usefulness remained, particularly considering the effort required. The Common Metrics Initiative should focus on facilitating cross-hub collaboration around metrics that address high-priority impact areas for individual hubs and the Consortium.

Enhancing Prehospital Outcomes for Cardiac Arrest (EPOC) study: sequential mixed-methods study protocol in Michigan, USA

INTRODUCTION

Out-of-hospital cardiac arrest (OHCA) is a common, life-threatening event encountered routinely by first responders, including police, fire and emergency medical services (EMS). Current literature suggests that there is significant regional variation in outcomes, some of which may be related to modifiable factors. Yet, there is a persistent knowledge gap regarding strategies to guide quality improvement efforts in OHCA care and, by extension, survival. The Enhancing Prehospital Outcomes for Cardiac Arrest (EPOC) study aims to fill these gaps and to improve outcomes.

METHODS AND ANALYSIS

This mixed-methods study includes three aims. In aim I, we will define variation in OHCA survival to the emergency department (ED) among EMS agencies that participate in the Michigan Cardiac Arrest Registry to Enhance Survival (CARES) in order to sample EMS agencies with high-survival and low-survival outcomes. In aim II, we will conduct site visits to emergency medical systems-including 911/dispatch, police, non-transport fire, and EMS agencies-in approximately eight high-survival and low-survival communities identified in aim I. At each site, key informant interviews and a multidisciplinary focus group will identify themes associated with high OHCA survival. Transcripts will be coded using a structured codebook and analysed through thematic analysis. Results from aims I and II will inform the development of a survey instrument in aim III that will be administered to all EMS agencies in Michigan. This survey will test the generalisability of factors associated with increased OHCA survival in the qualitative work to ultimately build an EPOC Toolkit which will be distributed to a broad range of stakeholders as a practical 'how-to' guide to improve outcomes.

ETHICS AND DISSEMINATION

The EPOC study was deemed exempt by the University of Michigan Institutional Review Board. Findings will be compiled in an 'EPOC Toolkit' and disseminated in the USA through partnerships including, but not limited to, policymakers, EMS leadership and health departments.

A scoping review of strategies for financing the implementation of evidence-based practices in behavioral health systems: State of the literature and future directions

Background:

Increased availability of evidence-based practices (EBPs) is essential to alleviating the negative public health and societal effects of behavioral health problems. A major challenge to implementing and sustaining EBPs broadly is the limited and fragmented nature of available funding.

Method:

We conducted a scoping review that assessed the current state of evidence on EBP financing strategies for behavioral health based on recent literature (i.e., post-Affordable Care Act). We defined financing strategies as techniques that secure and direct financial resources to support EBP implementation. This article introduces a conceptualization of financing strategies and then presents a compilation of identified strategies, following established reporting guidelines for the implementation strategies. We also describe the reported level of use for each financing strategy in the research literature.

Results:

Of 23 financing strategies, 13 were reported as being used within behavioral health services, 4 had potential for use, 5 had conceptual use only, and 1 was potentially contraindicated. Examples of strategies reported being used include increased fee-for-service reimbursement, grants, cost sharing, and pay-for-success contracts. No strategies had been evaluated in ways that allowed for strong conclusions about their impact on EBP implementation outcomes.

Conclusion:

The existing literature on EBP financing strategies in behavioral health raises far more questions than answers. Therefore, we propose a research agenda that will help better understand these financing strategies. We also discuss the implications of our findings for behavioral health professionals, system leaders, and policymakers who want to develop robust, sustainable financing for EBP implementation in behavioral health systems.

Plain language abstract:

Organizations that treat behavioral health problems (mental health and substance use) often seek to adopt and use evidence-based practices (EBPs). A challenge to adopting EBPs broadly is the limited funding available, often from various sources that are poorly coordinated with one another. To help organizations plan effectively to adopt EBPs, we conducted a review of recent evidence (i.e., since the passage of the 2010 Affordable Care Act) on strategies for financing EBP adoption in behavioral health systems. We present definitions of 23 identified strategies and describe each strategy’s reported (in the research literature) level of use to fund EBP adoption in behavioral health services. Of the 23 financing strategies, 13 strategies had evidence of use, 4 had potential for use, 5 had conceptual use only, and 1 was potentially contraindicated. Examples of strategies with evidence of use include increased fee-for-service reimbursement, grants, cost sharing, and pay-for-success contracts. This comprehensive list of EBP financing strategies may help guide decision-making by behavioral health professionals, system leaders, and policymakers. The article also presents a research agenda for building on the current research literature by (1) advancing methods to evaluate financing strategies’ effects, (2) partnering with stakeholders and decision-makers to examine promising financing strategies, (3) focusing on strategies and service systems with the greatest needs, (4) improving methods to guide the selection of financing strategies, and (5) paying greater attention to sustainable long-term financing of EBPs.

Effects of Health Care Payment Models on Physician Practice in the United States: Follow-Up Study

This study, sponsored by the American Medical Association (AMA), describes how alternative payment models (APMs) affect physicians, physicians' practices, and hospital systems in the United States and also provides updated data to the original 2014 study. Payment models discussed are core payment (fee for service, capitation, episode-based and bundled), supplementary payment (shared savings, pay for performance, retainer-based), and combined payment (medical homes and accountable care organizations). The effects of changes since 2014 in the Affordable Care Act (ACA) and of new alternative payment models (APMs), such as the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Quality Payment Program (QPP), are also examined. This project uses the same qualitative multiple-case study method as the 2014 study, relying primarily on semistructured interviews with physician practice leaders, physicians, and other observers. Findings describe the challenges posed by APMs, strategies adopted to deal with APMs, the effects of rapidly changing and increasingly complex payment models, and how risk aversion influences physician practices' decisions to engage in new payment models. Project findings are intended to help guide efforts by the AMA and other stakeholders to improve current and future APMs and help physician practices succeed in them.

Practice Expenses Associated with Comprehensive Primary Care Capabilities

Through the Comprehensive Primary Care (CPC) and Comprehensive Primary Care Plus (CPC+) programs, the Centers for Medicare & Medicaid Services (CMS) has encouraged primary care practices to invest in "comprehensive primary care" capabilities. Empirical evidence suggests these capabilities are under-reimbursed or not reimbursed under prevailing fee-for-service payment models. To help CMS design alternative payment models (APMs) that reimburse the costs of these capabilities, the authors developed a method for estimating related practice expenses. Fifty practices, sampled for diversity across CPC+ participation status, geographic region, rural status, size, and parent-organization affiliation, completed the study. Researchers developed a mixed-methods strategy, beginning with interviews of practice leaders to identify their capabilities and the types of costs incurred. This was followed by researcher-assisted completion of a workbook tailored to each practice, which gathered related labor and nonlabor costs. In a final interview, practice leaders reviewed cost estimates and made any needed corrections before approval. A main goal was to address a persistent question faced by CMS: When practices reported widely divergent costs for a given capability, was that divergence due to practices having different prices for the same capability or from their having substantially different capabilities? The cost estimation method developed in this project collected detailed data on practice capabilities and their costs. However, the small sample did not allow quantitative estimation of the contributions of service level and pricing to the variation in overall costs. This cost estimation method, deployed on a larger scale, could generate robust data to inform new payment models aimed at incentivizing and sustaining comprehensive primary care.

Congregational involvement in HIV: A qualitative comparative analysis of factors influencing HIV activity among diverse urban congregations

Religious congregations can potentially reach disproportionately affected populations with HIV programming, however, factors that influence congregational involvement in HIV are not well-studied. Utilizing comparative case methods and in-depth qualitative data from a diverse sample of 14 urban congregations, we examine a range of attitudinal, organizational, resource, and demographic factors to systematically identify different case scenarios-i.e., combinations of characteristics-associated with the level and types of HIV activities in which the congregational cases tended to be involved. For example, White or mixed race congregations with active gay constituencies and an African-American congregation with a strong lay HIV champion were among the high HIV involvement case scenarios, compared to African-American congregations with a health emphasis but no lay HIV champion among the medium HIV involvement scenarios, and fundamentalist African-American and Latino congregations among the low HIV involvement scenarios. Two key factors that appeared influential across case scenarios included the existence of lay champions for HIV activities and the general theological orientation of the congregation.

Examining differential performance of 3 medical home recognition programs

OBJECTIVES

We examined differences in patient outcomes associated with 3 patient-centered medical home (PCMH) recognition programs-National Committee for Quality Assurance (NCQA) Level 3, The Joint Commission (TJC), and Accreditation Association for Ambulatory Health Care (AAAHC)-among Medicare beneficiaries receiving care at federally qualified health centers (FQHCs).

STUDY DESIGN

We used data from CMS' FQHC Advanced Primary Care Practice Demonstration, in which participating FQHCs received assistance to achieve NCQA Level 3 PCMH recognition. We assessed the impact of the 3 recognition programs on utilization, quality, and Medicare expenditures using a sample of 1108 demonstration and comparison FQHCs.

METHODS

Using propensity-weighted difference-in-differences analyses, we compared changes in outcomes over 3 years for beneficiaries attributed to FQHCs that achieved each type of recognition relative to beneficiaries attributed to FQHCs that did not achieve recognition.

RESULTS

Recognized FQHCs, compared with nonrecognized FQHCs, were associated with significant 3-year changes in FQHC visits, non-FQHC primary care visits, specialty visits, emergency department (ED) visits, hospitalizations, a composite diabetes process measure, and Medicare expenditures. Changes varied in direction and strength by recognition type. In year 3, compared with nonrecognized sites, NCQA Level 3 sites were associated with greater increases in ambulatory visits and quality and greater reductions in hospitalizations and expenditures (P <.01), TJC sites were associated with significant reductions in ED visits and hospitalizations (P <.01), and AAAHC sites had changes in the opposite direction of what we anticipated.

CONCLUSIONS

Heterogeneous changes in beneficiary utilization, quality, and expenditures by recognition type may be explained by differences in recognition criteria, evaluation processes, and documentation requirements.

Pathways to Medical Home Recognition: A Qualitative Comparative Analysis of the PCMH Transformation Process

OBJECTIVE

To understand the process of practice transformation by identifying pathways for attaining patient-centered medical home (PCMH) recognition.

DATA SOURCES/STUDY SETTING

The CMS Federally Qualified Health Center (FQHC) Advanced Primary Care Practice Demonstration was designed to help FQHCs achieve NCQA Level 3 PCMH recognition and improve patient outcomes. We used a stratified random sample of 20 (out of 503) participating sites for this analysis.

STUDY DESIGN

We developed a conceptual model of structural, cultural, and implementation factors affecting PCMH transformation based on literature and initial qualitative interview themes. We then used conventional cross-case analysis, followed by qualitative comparative analysis (QCA), a cross-case method based on Boolean logic algorithms, to systematically identify pathways (i.e., combinations of factors) associated with attaining-or not attaining-Level 3 recognition.

DATA COLLECTION METHODS

Site-level indicators were derived from semistructured interviews with site leaders at two points in time (mid- and late-implementation) and administrative data collected prior to and during the demonstration period.

PRINCIPAL FINDINGS

The QCA results identified five distinct pathways to attaining PCMH recognition and four distinct pathways to not attaining recognition by the end of the demonstration. Across these pathways, one condition (change leader capacity) was common to all pathways for attaining recognition, and another (previous improvement or recognition experience) was absent in all pathways for not attaining recognition. In general, sites could compensate for deficiencies in one factor with capacity in others, but they needed a threshold of strengths in cultural and implementation factors to attain PCMH recognition.

CONCLUSIONS

Future efforts at primary care transformation should take into account multiple pathways sites may pursue. Sites should be assessed on key cultural and implementation factors, in addition to structural components, in order to differentiate interventions and technical assistance.

Using institutional theory to analyse hospital responses to external demands for finance and quality in five European countries

Objectives

Given the impact of the global economic crisis, delivering better health care with limited finance grows more challenging. Through the lens of institutional theory, this paper explores pressures experienced by hospital leaders to improve quality and constrain spending, focusing on how they respond to these often competing demands.

Methods

An in-depth, multilevel analysis of health care quality policies and practices in five European countries including longitudinal case studies in a purposive sample of ten hospitals.

Results

How hospitals responded to the financial and quality challenges was dependent upon three factors: the coherence of demands from external institutions; managerial competence to align external demands with an overall quality improvement strategy, and managerial stability. Hospital leaders used diverse strategies and practices to manage conflicting external pressures.

Conclusions

The development of hospital leaders’ skills in translating external requirements into implementation plans with internal support is a complex, but crucial, task, if quality is to remain a priority during times of austerity. Increasing quality improvement skills within a hospital, developing a culture where quality improvement becomes embedded and linking cost reduction measures to improving care are all required.

Implementing measurement-based care (iMBC) for depression in community mental health: a dynamic cluster randomized trial study protocol

Background

Measurement-based care is an evidence-based practice for depression that efficiently identifies treatment non-responders and those who might otherwise deteriorate [1]. However, measurement-based care is underutilized in community mental health with data suggesting fewer than 20 % of behavioral health providers using this practice to inform treatment. It remains unclear whether standardized or tailored approaches to implementation are needed to optimize measurement-based care fidelity and penetration. Moreover, there is some suggestion that prospectively tailored interventions that are designed to fit the dynamic context may optimize public health impact, though no randomized trials have yet tested this notion [2]. This study will address the following three aims: (1) To compare the effect of standardized versus tailored MBC implementation on clinician-level and client-level outcomes; (2) To identify contextual mediators of MBC fidelity; and (3) To explore the impact of MBC fidelity on client outcomes.

Methods/design

This study is a dynamic cluster randomized trial of standardized versus tailored measurement-based care implementation in Centerstone, the largest provider of community-based mental health services in the USA. This prospective, mixed methods implementation-effectiveness hybrid design allows for evaluation of the two conditions on both clinician-level (e.g., MBC fidelity) and client-level (depression symptom change) outcomes. Central to this investigation is the focus on identifying contextual factors (e.g., attitudes, resources, process, etc.) that mediate MBC fidelity and optimize client outcomes.

Discussion

This study will contribute generalizable and practical strategies for implementing systematic symptom monitoring to inform and enhance behavioral healthcare.

Facilitators and barriers to HIV activities in religious congregations: perspectives of clergy and lay leaders from a diverse urban sample

This paper examines facilitators and barriers to HIV activities within religious congregations, the relative internal or external sources of these influences, and suggestive differences across congregational types. Results are based on in-depth interviews with clergy and lay leaders (n = 57) from 14 congregations in Los Angeles County, California, purposively selected to reflect diversity in racial-ethnic composition, denomination, size, and HIV activity level. Many common facilitators and barriers were related to norms and attitudes, only a few of which appeared overtly associated with theological orientations. Clergy support was a facilitator particularly prevalent among congregations having higher HIV activity levels, indicating its importance in sustaining and expanding HIV programs. Resource issues were also prominent, with material resource barriers more frequently mentioned by smaller congregations and human resource barriers more among larger congregations. Organizational structure issues were mostly centered on external linkages with various social service, public health, and faith-based entities. Analysis of internal versus external sources highlights the roles of different stakeholders within and outside congregations in promoting HIV activities. Potential differences across congregational types represent fruitful areas for future research.

Perspectives on Federal Funding for State Health Care-Associated Infection Programs: Achievements, Barriers, and Implications for Sustainability

In September 2009, federal funding for health care-associated infection (HAI) program development was dispersed through a cooperative agreement to 51 state and territorial health departments. From July to September 2011, 69 stakeholders from six states-including state health department employees, representatives from partner organizations, and health care facility employees-were interviewed to assess state HAI program achievements, implementation barriers, and strategies for sustainability. Respondents most frequently cited enhanced HAI surveillance as a program achievement and resource constraints as an implementation barrier. To sustain programs, respondents recommended ongoing support for HAI prevention activities, improved surveillance processes, and maintenance of partnerships. Findings suggest that state-level HAI program growth was achieved during the cooperative agreement but that maintenance of programs faces challenges.

Approach for conducting the longitudinal program evaluation of the US Department of Health and Human Services National Action Plan to prevent healthcare-associated infections: roadmap to elimination

BACKGROUND

In response to mounting evidence about skyrocketing morbidity, mortality, and costs associated with healthcare-associated infections (HAIs), in 2009, the US Department of Health and Human Services (HHS) issued the HHS HAI Action Plan to enhance collaboration and coordination and to strengthen the impact of national efforts to address HAIs. To optimize timely understanding of the Action Plan's approach and outcomes, as well as improve the likely success of this effort, HHS requested an independent longitudinal and formative program evaluation.

OBJECTIVES

This article describes the evaluation approach to assessing HHS's progress and the challenges encountered as HHS attempted to transform the national strategy to HAI elimination.

RESEARCH DESIGN

The Context-Input-Process-Product (CIPP) model, a structured-yet-flexible formative and summative evaluation tool, supported the assessment of: (1) the Context in which the Action Plan developed, (2) the Inputs and decisions made about selecting activities for implementation, (3) Processes or implementation of selected activities, and (4) Products and outcomes.

MEASURES

A system framework consisting of 4 system functions and 5 system properties.

RESULTS

The CIPP evaluation model provides a structure for tracking the components of the program, the relationship between components, and the way in which components change with time. The system framework allows the evaluation team to understand what the Action Plan is doing and how it aims to facilitate change in the healthcare system to address the problem of HAIs.

CONCLUSIONS

With coordination and alignment becoming increasingly important among large programs within healthcare and other fields, program evaluations like this can inform the policy community about what works and why, and how future complex large-scale programs should be evaluated.

The organization of HIV and other health activities within urban religious congregations

Most religious congregations in the USA are involved with some type of social service activity, including health activities. However, relatively few formally engage with people with HIV, and many have reported barriers to introducing HIV prevention activities. We conducted a qualitative case study of HIV involvement among 14 urban congregations in Los Angeles County in 2007. In-depth qualitative interviews of lay leaders and clergy were analyzed for themes related to HIV and other health activities, including types of health issues addressed, types of activities conducted, how activities were organized, and the relationship between HIV and other health activities. We identified three primary models representing how congregations organized HIV and other health activities: (1) embedded (n = 7), where HIV activities were contained within other health activities; (2) parallel (n = 5), where HIV and other health activities occurred side by side and were organizationally distinct; (3) overlap (n = 2), where HIV and non-HIV health efforts were conducted by distinct groups, but shared some members and organization. We discuss implications of each model for initiating and sustaining HIV activities within urban congregations over time.

Implementation of the CALM intervention for anxiety disorders: a qualitative study

BACKGROUND

Investigators recently tested the effectiveness of a collaborative-care intervention for anxiety disorders: Coordinated Anxiety Learning and Management(CALM) []) in 17 primary care clinics around the United States. Investigators also conducted a qualitative process evaluation. Key research questions were as follows: (1) What were the facilitators/barriers to implementing CALM? (2) What were the facilitators/barriers to sustaining CALM after the study was completed?

METHODS

Key informant interviews were conducted with 47 clinic staff members (18 primary care providers, 13 nurses, 8 clinic administrators, and 8 clinic staff) and 14 study-trained anxiety clinical specialists (ACSs) who coordinated the collaborative care and provided cognitive behavioral therapy. The interviews were semistructured and conducted by phone. Data were content analyzed with line-by-line analyses leading to the development and refinement of themes.

RESULTS

Similar themes emerged across stakeholders. Important facilitators to implementation included the perception of "low burden" to implement, provider satisfaction with the intervention, and frequent provider interaction with ACSs. Barriers to implementation included variable provider interest in mental health, high rates of part-time providers in clinics, and high social stressors of lower socioeconomic-status patients interfering with adherence. Key sustainability facilitators were if a clinic had already incorporated collaborative care for another disorder and presence of onsite mental health staff. The main barrier to sustainability was funding for the ACS.

CONCLUSIONS

The CALM intervention was relatively easy to incorporate during the effectiveness trial, and satisfaction was generally high. Numerous implementation and sustainability barriers could limit the reach and impact of widespread adoption. Findings should be interpreted with the knowledge that the ACSs in this study were provided and trained by the study. Future research should explore uptake of CALM and similar interventions without the aid of an effectiveness trial.

Attitudes and beliefs related to HIV/AIDS in urban religious congregations: barriers and opportunities for HIV-related interventions

HIV-related stigmas have been seen as a barrier to greater religious congregation involvement in HIV prevention and care in the United States and elsewhere. We explored congregational and community norms and attitudes regarding HIV, sexuality, and drug use through a qualitative case study of 14 diverse religious congregations in Los Angeles County, California between December 2006 and May 2008. Data collected included semi-structured interviews with 57 clergy and lay leaders across the congregations, structured observations of congregational activities, review of archival documents, and a questionnaire on congregational characteristics. Across and within congregations, we found a wide range of views towards HIV, people with HIV, and populations at risk for HIV, from highly judgmental and exclusionary, to "loving the sinner, not the sin," to accepting and affirming. Attitudes and norms about HIV, homosexuality, and substance abuse appeared to be related to the type and intensity of congregational HIV-related activities. However, even among the higher activity congregations, we found a range of perceptions, including ones that were stigmatizing. Results suggest that affirming norms and attitudes are not a prerequisite for a congregation to initiate HIV activities, a finding relevant for HIV service providers and researchers seeking to engage congregations on this issue. HIV stigma reduction is not a prerequisite for congregational HIV involvement: both may occur simultaneously, or one before the other, and they dynamically affect each other. Strategies that are congruent with congregations' current levels of comfort and openness around HIV can themselves facilitate a process of attitudinal and normative change.

Partnered evaluation of a community engagement intervention: use of a kickoff conference in a randomized trial for depression care improvement in underserved communities

Community partnered research and engagement strategies are gaining recognition as innovative approaches to improving health care systems and reducing health disparities in underserved communities. These strategies may have particular relevance for mental health interventions in low income, minority communities in which there often is stigma and silence surrounding conditions such as depression and difficulty in implementing improved access and quality of care. At the same time, there is a relative dearth of evidence on the effectiveness of specific community engagement interventions and on the design, process, and context of these interventions necessary for understanding their implementation and generalizability. This article evaluates one of a number of community engagement strategies employed in the Community Partners in Care (CPIC) study, the first randomized controlled trial of the role of community engagement in adapting and implementing evidence-based depression care. We specifically describe the unique goals and features of a community engagement kickoff conference as used in CPIC and provide evidence on the effectiveness of this type of intervention by analyzing its impact on: 1) stimulating a dialog sense of collective efficacy, and opportunities for learning and networking to address depression and depression care in the community; 2) activating interest and participation in CPIC's randomized trial of two different ways to implement evidence-based quality improvement programs for depression across diverse community agencies; and 3) introducing evidence-based toolkits and collaborative care models to potential participants in both intervention conditions and other community members. We evaluated the effectiveness of the conference through a community-partnered process in which both community and academic project members were involved in study design, data collection and analysis. Data sources include participant conference evaluation forms (n = 187 over two conferences; response rate 59%) and qualitative observation field notes of each conference session. Mixed methods for the analysis consist of descriptive statistics of conference evaluation form ratings, as well as thematic analysis of evaluation form write-in comments and qualitative observation notes. Results indicate the effectiveness of this type of event for each of the three main goals, and provide insights into intervention implementation and use of similar community engagement strategies for other studies.

The growth of partnerships to support patient safety practice adoption

OBJECTIVES

To document the numbers and types of interorganizational partnerships within the national patient safety domain, changes over time in these networks, and their potential for disseminating patient safety knowledge and practices.

DATA SOURCES

Self-reported information gathered from representatives of national-level organizations active in promoting patient safety.

STUDY DESIGN

Social network analysis was used to examine the structure and composition of partnership networks and changes between 2004 and 2006.

DATA COLLECTION

Two rounds of structured telephone interviews (n=35 organizations in 2004 and 55 in 2006).

PRINCIPAL FINDINGS

Patient safety partnerships expanded between 2004 and 2006. The average number of partnerships per interviewed organization increased 40 percent and activities per reported partnership increased over 50 percent. Partnerships increased in all activity domains, particularly dissemination and tools development. Fragmentation of the overall partnership network decreased and potential for information flow increased. Yet network centralization increased, suggesting vulnerability to partnership failure if key participants disengage.

CONCLUSIONS

Growth in partnerships signifies growing strength in the capacity to disseminate and implement patient safety advancements in the U.S. health care system. The centrality of AHRQ in these networks of partnerships bodes well for its leadership role in disseminating information, tools, and practices generated by patient safety research projects.

Community Partners in Care: Leveraging Community Diversity to Improve Depression Care for Underserved Populations

Research suggests that the quality and outcomes of depression treatment for adults can be substantially improved through "collaborative care" programs. However, there is a lack of resources required to implement such programs in vulnerable communities. Our paper examines the planning phase of the Community Partners in Care (CPIC) initiative, which addresses this problem through a unique approach in which academic institutions partner directly with a wide range of community-based and service organizations in all phases of the project fielded in two underserved communities in Los Angeles. CPIC offers a unique opportunity to understand how diverse organizations can work together to address community depression care needs and to analyze the potential strengths and tradeoffs of coordinating among such varied entities. This article focuses on intra-group dynamics that surround the process of participatory research and reports results of the first wave of process evaluation of the planning phase of the CPIC initiative. Our analysis explores two main themes: Community-Partnered Participatory Research and benefits and challenges of collaboration in diverse groups.

Interventions in organizational and community context: a framework for building evidence on dissemination and implementation in health services research

The effective dissemination and implementation of evidence-based health interventions within community settings is an important cornerstone to expanding the availability of quality health and mental health services. Yet it has proven a challenging task for both research and community stakeholders. This paper presents the current framework developed by the UCLA/RAND NIMH Center to address this research-to-practice gap by: (1) providing a theoretically-grounded understanding of the multi-layered nature of community and healthcare contexts and the mechanisms by which new practices and programs diffuse within these settings; (2) distinguishing among key components of the diffusion process-including contextual factors, adoption, implementation, and sustainment of interventions-showing how evaluation of each is necessary to explain the course of dissemination and outcomes for individual and organizational stakeholders; (3) facilitating the identification of new strategies for adapting, disseminating, and implementing relatively complex, evidence-based healthcare and improvement interventions, particularly using a community-based, participatory approach; and (4) enhancing the ability to meaningfully generalize findings across varied interventions and settings to build an evidence base on successful dissemination and implementation strategies.

How do teams in quality improvement collaboratives interact?

BACKGROUND

The multi-organizational collaborative is a popular model for quality improvement (QI) initiatives. It assumes organizations will share information and social support. However, there is no comprehensive documentation of the extent to which teams do interact. Considering QI collaboratives as networks, interactions among reams were documented, and the associations between network roles and performance were examined.

METHODS

A telephone survey of official team contact persons for 94 site teams in three QI collaborarives was conducted in 2002 and 2003. Four performance measures were used to assess the usefulness of ties to other teams and being considered a leader by peers.

RESULTS

Eighty percent of the teams said they would contact another team again if they felt the need. Teams made a change as a direct result of interaction in 86% of reported relationships. Teams typically exchanged tools such as software and interacted outside of planned activities. Having a large number of ties to other teams is strongly related to the number of mentions as a leader. Both of these variables are related to faculty-assessed performance, number of changes the ream made to improve care, and depth of those changes.

DISCUSSION

The Findings suggest that collaborative teams do indeed exchange important information, and the social dynamics of the collaborarives contribute to individual and collaborative success.

Assessing organizational readiness and change in community intervention research: framework for participatory evaluation

This paper describes a study currently underway that uses a collaborative approach to assess organizational capacity to form partnerships around mental health and substance abuse care. Employing many of the principles of community-based participatory research, the study's primary objective is to collaboratively develop a conceptual understanding and generalizable, practical measures of organizational capacity. The intent of this collaborative approach is to increase the rigor and relevance of the assessment framework while strengthening the ability of health partnerships and stakeholders to understand and track community organizational capacity. The study investigators developed an initial model of community dissemination based on the research literatures on organizations and the diffusion of innovations. Through the collaborative process, the specific goals of the project shifted substantially to match the partnership interests and concerns of community agencies. One of the benefits of a collaborative approach has been to use researchers' academic knowledge to catalogue potential factors and the wealth of community coinvestigators' experiential knowledge of interagency dynamics to identify specific relevant dimensions of capacity. This initial exploratory study represents a first step toward developing a general approach to conceptualizing and tracking the organizational capacity of communities. The model and measurement framework may have wider applicability to capacities to partner around and implement a variety of health-related interventions within communities.

Implementation and maintenance of quality improvement for treating depression in primary care

OBJECTIVE

Little is known about the long-term success of quality improvement efforts for the treatment of depression in primary care. This study assessed factors associated with the successful implementation, maintenance, and spread of such efforts.

METHODS

The authors conducted an independent process evaluation of data from monthly progress reports and 18-month telephone interviews from multidisciplinary quality improvement teams in 17 diverse primary care organizations that participated in the Institute for Healthcare Improvement's Breakthrough Series for Depression from February 2000 through March 2001.

RESULTS

All sites made changes toward improving care in three of six categories: delivery system redesign, self-management strategies, and information systems. The changes that were most commonly viewed as major successes were delivery system changes (ten sites, or 59 percent) and information system changes (nine sites, or 53 percent); these types of changes were also the most often sustained over time (ten sites, or 59 percent, and 16 sites, or 94 percent, respectively). Fifteen sites made changes in decision support, community linkages, and health system support but were less likely to view these changes as major successes or to sustain them. Organizational structure and leadership support were the most common facilitators. Staff resistance, time constraints, and information technology were the most common barriers. Implementation strategies varied with sets of barriers.

CONCLUSIONS

Despite substantial challenges, there was evidence of broad success at implementation and maintenance of quality improvement for depression treatment in primary care.

Motivation to Change Chronic Illness Care

This article examines the motivation of health care professionals to improve quality of chronic illness care using the Chronic Care Model and Plan-Do-Study-Act cycles. The findings suggest that organizational attempts to redesign care require support of activities initiated by practitioners and managers and an organizational commitment to quality improvement.

The role of perceived team effectiveness in improving chronic illness care

BACKGROUND/OBJECTIVES

The importance of teams for improving quality of care has received increased attention. We examine both the correlates of self-assessed or perceived team effectiveness and its consequences for actually making changes to improve care for people with chronic illness. STUDY SETTING AND METHODS: Data were obtained from 40 teams participating in the national evaluation of the Improving Chronic Illness Care Program. Based on current theory and literature, measures were derived of organizational culture, a focus on patient satisfaction, presence of a team champion, team composition, perceived team effectiveness, and the actual number and depth of changes made to improve chronic illness care.

RESULTS

A focus on patient satisfaction, the presence of a team champion, and the involvement of the physicians on the team were each consistently and positively associated with greater perceived team effectiveness. Maintaining a balance among culture values of participation, achievement, openness to innovation, and adherence to rules and accountability also appeared to be important. Perceived team effectiveness, in turn, was consistently associated with both a greater number and depth of changes made to improve chronic illness care. The variables examined explain between 24 and 40% of the variance in different dimensions of perceived team effectiveness; between 13% and 26% in number of changes made; and between 20% and 42% in depth of changes made.

CONCLUSIONS

The data suggest the importance of developing effective teams for improving the quality of care for patients with chronic illness.

An organizational field approach to resource environments in healthcare: comparing entries of hospitals and home health agencies in the San Francisco Bay region

OBJECTIVE

To draw together insights from three perspectives (health economics, organizational ecology, and institutional theory) in order to clarify the factors that influence entries of providers into healthcare markets. A model centered on the concept of an organizational field is advanced as the level of analysis best suited to examining the assortment and interdependence of organizational populations and the institutional forces that shape this co-evolution. In particular, the model argues that: (1) different populations of healthcare providers partition fiscal, geographic, and demographic resource environments in order to ameliorate competition and introduce service complementarities; and (2) competitive barriers to entry within populations of providers vary systematically with regulatory regimens.

DATA SOURCES

County-level entries of hospitals and home health agencies in the San Francisco Bay Area using data from the American Hospital Association (1945-1991) and California's Office of Statewide Health Planning and Development (1976-1991). Characteristics of the resource environment are derived from the Area Resource File (ARF) and selected government censuses.

METHODS OF ANALYSIS

A comparative design is applied to contrast influences on hospital and home health agency entries during the post-World War II period. Empirical estimates are obtained using Poisson and negative binomial regression models.

RESULTS

Hospital and HHA markets are partitioned primarily by the age and education of consumers and, to a lesser extent, by urbanization levels and public funding expenditures. Such resource partitioning allows independent HHAs to exist comfortably in concentrated hospital markets. For both hospitals and HHAs, the barriers to entry once generated by oligopolistic concentration have declined noticeably with the market-oriented reforms of the past 15 years.

CONCLUSION

A field-level perspective demonstrates that characteristics of local resource environments interact with interdependencies of provider populations and broader regulatory regimes to affect significantly the types of provider organizations likely to enter a given healthcare market.

The differential regulation of the circulating levels of the insulin-like growth factors and their binding proteins (IGFBP) 1, 2 and 3 after elective abdominal surgery

OBJECTIVES

Patients undergoing abdominal surgery often suffer from morbidity associated with increased protein catabolism. Therapeutic recombinant human insulin-like growth factor (rhIGF)-I has been proposed as a means of reversing this process. As IGFBPs modulate the bioavailability of the IGFs, we have studied the changes in the circulating levels of these peptides during surgery.

DESIGN

Patients undergoing elective intestinal surgery were recruited prospectively. Blood samples were taken before, during and after surgery. Standard anaesthetic techniques were used.

METHODS

Twelve adults (aged 30-70 years; 9 female, 3 male) undergoing surgery were studied. Serum was taken before premedication (preop), end of surgery (end surg), 2 h, 6 h post surgery, on days 1-4, 7, 10 and 14, and on recovery at 6 weeks.

MEASUREMENTS

Serum IGF-I, IGF-II, IGFBP-1, IGFBP-2, IGFBP-3, insulin and C-peptide were measured by radioimmunoassay. IGFBP profiles were also assessed by Western ligand blot (WLB). Samples taken preop and at 2 days were separated by fast-phase liquid chromatography (FPLC) using a Superose 12 column under neutral conditions (pH 7.4), and the fractions were analysed subsequently by WLB and immunoblot using a specific IGFBP-3 antiserum.

RESULTS

IGF-I fell rapidly during surgery from 170 +/- 21 (preop) to 133 +/- 14 micrograms/l (end surg) (P < 0.05). The magnitude of this fall could not be explained by haemodilution. IGF-I levels then fell further to a nadir of 103 +/- 10 micrograms/l at day 4 (P < 0.05). IGF-II fell from 580 +/- 46 (preop) to 397 +/- 38 micrograms/l (day 2). Both IGF-I and IGF-II recovered to preop levels at 6 weeks (205 +/- 14 micrograms/l and 623 +/- 30 micrograms/l respectively). IGFBP-3 levels fell similarly from 4.46 +/- 0.45 to 3.2 +/- 0.3 mg/l (end surg) and to a nadir of 2.66 +/- 0.19 mg/l at day 2. There was a close correlation between IGFBP-3 levels and the sum of IGF-I and IGF-II levels before surgery (r = 0.9, P < 0.01) and this was maintained throughout the post-operative period (mean correlation coefficient of 0.86 +/- 0.02, P < 0.05). On days 2 and 3 there was a small but significant increase in the ratio between serum IGF-I and IGFBP-3 levels compared with the preop ratio (P < 0.05 and < 0.005, respectively). WLB demonstrated almost complete absence of IGFBP-3 by day 2. This discrepancy between RIA and WLB analysis of IGFBP-3 suggested the presence of IGFBP-3 protease activity between days 1 and 4. This was confirmed by WLB and immunoblot analyses of samples taken 2 days after surgery. The decrease in IGFBP-3 on WLB was shown to be associated with an increase in the proteolytically cleaved fragments of IGFBP-3. These fragments following FPLC were detected in the high molecular weight fractions, suggesting that the fragments were still able to form the high molecular weight IGFBP-3/ALS complex which is thought to form only when IGF is bound by IGFBP-3. IGFBP-1 levels rose during surgery (mean duration of surgery was 125 minute) from 18 +/- 3 (preop) to 51 +/- 12 micrograms/l (end surg) (P < 0.05). This rise in IGFBP-1 paralleled increases in insulin from 7.3 +/- 1.0 to 20.8 +/- 7.5 mU/l and glucose from 4.6 +/- 0.3 to 8.7 +/- 1.2 mmol/l. IGFBP-1 levels then fell to basal values by 6 hours. IGFBP-2, in contrast, fell slightly during surgery from 636 +/- 14 to 599 +/- 96 mg/l and then returned to basal levels by 6 hours.

CONCLUSION

After major surgery there are complex and diverse changes in the IGFs and IGFBPs. The effect of these changes on IGF bioavailability may significantly affect the therapeutic potential of IGF-I in this setting.

Alfentanil suppresses coughing and agitation during emergence from isoflurane anesthesia

STUDY OBJECTIVE

To evaluate the effectiveness of alfentanil in suppressing coughing and agitation during emergence from isoflurane anesthesia.

DESIGN

Randomized, double-blind, placebo-controlled study.

SETTING

Operating rooms at a university medical center.

PATIENTS

34 healthy ASA physical status I and II adult patients scheduled to undergo oral surgical procedures.

INTERVENTIONS

During emergence from anesthesia, patients received either alfentanil 15 micrograms/kg (in 10 ml) or saline (10 ml) when the end-tidal isoflurane concentration reached 0.3%.

MEASUREMENTS AND MAIN RESULTS

Hemodynamic variables were measured at one-minute intervals following administration of the study medication. A blinded observer recorded the time for patients to spontaneously open their eyes and to follow commands after discontinuing the isoflurane. The occurrence of coughing and agitation prior to extubation was noted. Patients in the alfentanil treatment group exhibited a reduced incidence of coughing prior to extubation (6% vs. 83%, respectively) and a longer time interval until the onset of spontaneous movements (21.1 +/- 2.6 min vs. 14.6 +/- 1.7 min, respectively). The interval between the onset of movement and orientation was shorter in the alfentanil-treated patients, resulting in similar extubation times for both groups. Alfentanil administration was also associated with lower heart rate, systolic diastolic, and mean arterial pressure values during the emergence period.

CONCLUSION

Alfentanil decreased coughing, agitation, and cardiovascular stimulation during emergence from isoflurane anesthesia without prolonging the time of extubation.

Oxygen supply failure revisited

This is a report of a previously undescribed cause of oxygen supply failure during anesthesia, resulting from a worn main switch on a Narkomed 2A anesthesia machine (North American Dräger Information Systems, Telford, PA). The implications of this incident are discussed.

Thyrotoxicosis presenting as a life threatening hypokalaemic paralysis: investigation of the Na/K pump in isolated leucocytes

A 37-year-old Chinese man presented with the rapid onset of profound muscle weakness, and a serum potassium of 1.7 mmol/l. The intravenous infusion of undiluted potassium chloride (2 mmol/ml) through a central venous catheter resulted in rapid recovery. Further investigation revealed thyrotoxicosis. He was treated with carbimazole and subsequently remained well. We assessed Na/K pump activity in isolated leucocytes taken from the patient and found an exaggerated response to adrenaline which ceased after he became euthyroid.

Anaesthesia for procedures on the larynx and pharynx. The use of the Bullard laryngoscope in conjunction with high frequency jet ventilation

Twenty patients undergoing elective procedures on the larynx and pharynx were anaesthetised using a propofol infusion and a bolus of vecuronium. High frequency jet ventilation was employed via a 7 French gauge catheter, with a second catheter being used to measure expired carbon dioxide levels. The Bullard laryngoscope was compared with the Macintosh instrument both for visualising the larynx and subsequently inserting a catheter. One catheter was left in place until the patient was fully awake, and in one case this enabled gas exchange to be maintained in the presence of laryngospasm. Using the Bullard laryngoscope, intubation was possible in all 20 patients, in a mean time of 22 (6.8) s. Using the Macintosh laryngoscope only 16 patients could be intubated and this took significantly longer at 34 (18.3) s (p < 0.05). The Bullard laryngoscope and high frequency jet ventilation offer a reliable method of intubating and anaesthetising patients with upper airways pathology and further benefits may accrue in the recovery period.

New methods of dealing with the complications of panendoscopy

A 70-year-old man with chronic obstructive airways disease was scheduled to undergo panendoscopy following a course of radiotherapy for carcinoma of the larynx. He was anaesthetized using a propofol infusion and high frequency jet ventilation (HFJV). The jet ventilation catheter was left in situ at the end of the procedure. This enabled oxygenation to be maintained in the presence of post-operative laryngospasm by re-attaching the jet ventilator. Subsequently he developed respiratory failure, and a Bullard laryngoscope was used to visualize the vocal folds despite oedema of the tumour which made direct laryngoscopy impossible. A catheter was passed through the biopsy channel of the Bullard, enabling HFJV to be commenced. A conventional endotracheal tube was then railroaded over the catheter to facilitate conventional ventilation.

Interhospital Transfers by Helicopter: The First 50 Patients of the Careflight Project

An interhospital helicopter transfer service was set up using a dedicated helicopter fitted with medical equipment and staffed by anaesthetists. The system proved to be safe and practical.

Fifty patients were referred from 38 hospitals throughout the UK, with 84% of transfers preplanned. Patients were transferred a mean distance of 118 miles (range 35–397 miles) and there was no deterioration during transfer as measured by pre and post transfer sickness scores. Twenty-eight per cent of cases could not have been practically transferred by conventional means.

The death rate of 20% was lower than that reported for specially equipped and staffed land transfer systems, which may indicate less physiological deterioration in the critically ill compared to road transfer. Dedicated helicopter transfer resulted in a 50% survival rate in patients with a sickness score over 18, a group found not to survive after land transfer. There was no correlation between distance moved and outcome.

A helicopter transfer system using suitable equipment and staff is a practical and safe method of moving critically ill patients between hospitals, and may be preferable to land transfer for distances in excess of 25 miles.
