1.  Evolving Prehospital, Emergency Department, and “Inpatient” Management Models for Geriatric Emergencies 
Clinics in geriatric medicine  2013;29(1):10.1016/j.cger.2012.09.003.
Alternative management methods are essential to ensure high quality and efficient emergency care for the growing number of geriatric adults worldwide. Protocols for case-finding and rapid diagnosis to support early condition-specific treatment for older adults with acute severe illness and injury are needed. Improved emergency department care for older adults will require providers to look beyond the diagnosis to address the influence of other factors on the patient's health: isolation and depression; finances and transportation; and chronic medical conditions and polypharmacy. This review article describes recent and ongoing efforts to enhance the quality of emergency care for older adults using alternative management approaches spanning the spectrum from prehospital care, through the emergency department, and into evolving inpatient or outpatient processes of care.

2.  Lower tidal volume at initiation of mechanical ventilation may reduce progression to acute respiratory distress syndrome: a systematic review 
Critical Care  2013;17(1):R11.
Introduction
The most appropriate tidal volume in patients without acute respiratory distress syndrome (ARDS) is controversial and has not been rigorously examined. Our objective was to determine whether a mechanical ventilation strategy using lower tidal volume is associated with a decreased incidence of progression to ARDS when compared with a higher tidal volume strategy.
Methods
A systematic search of MEDLINE, EMBASE, CINAHL, the Cochrane Library, conference proceedings, and clinical trial registration was performed with a comprehensive strategy. Studies providing information on mechanically ventilated patients without ARDS at the time of initiation of mechanical ventilation, and in which tidal volume was independently studied as a predictor variable for outcome, were included. The primary outcome was progression to ARDS.
Results
The search yielded 1,704 studies, of which 13 were included in the final analysis. One randomized controlled trial was found; the remaining 12 studies were observational. The patient cohorts were significantly heterogeneous in composition and baseline risk for developing ARDS; therefore, a meta-analysis of the data was not performed. The majority of the studies (n = 8) showed a decrease in progression to ARDS with a lower tidal volume strategy. ARDS developed early in the course of illness (5 hours to 3.7 days). The development of ARDS was associated with increased mortality, lengths of stay, mechanical ventilation duration, and nonpulmonary organ failure.
Conclusions
In mechanically ventilated patients without ARDS at the time of endotracheal intubation, the majority of data favors lower tidal volume to reduce progression to ARDS. However, due to significant heterogeneity in the data, no definitive recommendations can be made. Further randomized controlled trials examining the role of lower tidal volumes in patients without ARDS, controlling for ARDS risk, are needed.

4.  The Six-Item Screener and AD8 for the Detection of Cognitive Impairment in Geriatric Emergency Department Patients 
Annals of emergency medicine  2010;57(6):653-661.
Study objective
We evaluate the diagnostic test characteristics of the Six-Item Screener and the AD8 to detect cognitive dysfunction in adults older than 65 years and using the emergency department (ED) for any reason.
Methods
We conducted an observational cross-sectional cohort study at a single academic urban university-affiliated hospital. Subjects were consenting, non-critically ill, English-speaking adults older than 65 years and receiving care in the ED. We quantitatively assessed the diagnostic test characteristics of the Six-Item Screener and AD8 by using the Mini-Mental State Examination score less than 24 as the criterion standard for cognitive dysfunction.
Results
The prevalence of cognitive dysfunction was 35%, but only 6% of charts noted a pre-existing deficit. The Six-Item Screener was superior to either the caregiver-administered AD8 or the patient-administered AD8 for the detection of cognitive dysfunction.
Conclusion
The Six-Item Screener was superior to the caregiver- or patient-administered AD8 to identify older adults at increased risk for occult cognitive dysfunction.

5.  A Compilation of Strategies for Implementing Clinical Innovations in Health and Mental Health 
Efforts to identify, develop, refine, and test strategies to disseminate and implement evidence-based treatments have been prioritized in order to improve the quality of health and mental healthcare delivery. However, this task is complicated by an implementation science literature characterized by inconsistent language use and inadequate descriptions of implementation strategies. This article brings more depth and clarity to implementation research and practice by presenting a consolidated compilation of discrete implementation strategies, based upon a review of 205 sources published between 1995 and 2011. The resulting compilation includes 68 implementation strategies and definitions, which are grouped according to six key implementation processes: planning, educating, financing, restructuring, managing quality, and attending to the policy context. This consolidated compilation can serve as a reference to stakeholders who wish to implement clinical innovations in health and mental healthcare and can facilitate the development of multifaceted, multilevel implementation plans that are tailored to local contexts.

6.  Consensus Conference Follow-up: Inter-rater Reliability Assessment of the Best Evidence in Emergency Medicine (BEEM) Rater Scale, a Medical Literature Rating Tool for Emergency Physicians 
Academic Emergency Medicine  2011;18(11):1193-1200.
Background
Studies published in general and specialty medical journals have the potential to improve emergency medicine (EM) practice, but there can be delayed awareness of this evidence because emergency physicians (EPs) are unlikely to read most of these journals. Also, not all published studies are intended for or ready for clinical practice application. The authors developed “Best Evidence in Emergency Medicine” (BEEM) to ameliorate these problems by searching for, identifying, appraising, and translating potentially practice-changing studies for EPs. An initial step in the BEEM process is the BEEM rater scale, a novel tool for EPs to collectively evaluate the relative clinical relevance of EM-related studies found in more than 120 journals. The BEEM rater process was designed to serve as a clinical relevance filter to identify those studies with the greatest potential to affect EM practice. Therefore, only those studies identified by BEEM raters as having the highest clinical relevance are selected for the subsequent critical appraisal process and, if found methodologically sound, are promoted as the best evidence in EM.
Objectives
The primary objective was to measure inter-rater reliability (IRR) of the BEEM rater scale. Secondary objectives were to determine the minimum number of EP raters needed for the BEEM rater scale to achieve acceptable reliability and to compare performance of the scale against a previously published evidence rating system, the McMaster Online Rating of Evidence (MORE), in an EP population.
Methods
The authors electronically distributed the title, conclusion, and a PubMed link for 23 recently published studies related to EM to a volunteer group of 134 EPs. The volunteers answered two demographic questions and rated the articles using one of two randomly assigned seven-point Likert scales, the BEEM rater scale (n = 68) or the MORE scale (n = 66), over two separate administrations. The IRR of each scale was measured using generalizability theory.
Results
The IRR of the BEEM rater scale ranged between 0.90 (95% confidence interval [CI] = 0.86 to 0.93) to 0.92 (95% CI = 0.89 to 0.94) across administrations. Decision studies showed a minimum of 12 raters is required for acceptable reliability of the BEEM rater scale. The IRR of the MORE scale was 0.82 to 0.84.
Conclusions
The BEEM rater scale is a highly reliable, single-question tool for a small number of EPs to collectively rate the relative clinical relevance within the specialty of EM of recently published studies from a variety of medical journals. It compares favorably with the MORE system because it achieves a high IRR despite simply requiring raters to read each article’s title and conclusion.

7.  High Yield Research Opportunities in Geriatric Emergency Medicine: Prehospital Care, Delirium, Adverse Drug Events, and Falls 
Emergency services constitute crucial and frequently used safety nets for older persons, an emergency visit by a senior very often indicates high vulnerability for functional decline and death, and interventions via the emergency system have significant opportunities to change the clinical course of older patients who require its services. However, the evidence base for widespread employment of emergency system-based interventions is lacking. In this article, we review the evidence and offer crucial research questions to capitalize on the opportunity to optimize health trajectories of older persons seeking emergency care in four areas: prehospital care, delirium, adverse drug events, and falls.

8.  Research Priorities for High Quality Geriatric Emergency Care: Medication Management, Screening and Prevention and Functional Assessment 
Background
Geriatric adults represent an increasing proportion of emergency department (ED) users, and can be particularly vulnerable to acute illnesses. Health care providers have recently begun to focus upon the development of quality indicators to define a minimal standard of care.
Objectives
The original objective of this project was to develop additional ED-specific quality indicators for older patients within the domains of medication management, screening and prevention, and functional assessment, but the quantity and quality of evidence was insufficient to justify unequivocal minimal standards of care for these three domains. Accordingly, the authors modified the project objectives to identify key research opportunities within these three domains that can be used to develop quality indicators in the future.
Methods
Each domain was assigned one or two content experts who created potential quality indicators (QI) based on a systematic review of the literature, supplemented by expert opinion. Candidate quality indicators were then reviewed by four groups: the Society for Academic Emergency Medicine (SAEM) Geriatric Task Force, the SAEM Geriatric Interest Group, and audiences at the 2008 SAEM Annual Meeting and the 2009 American Geriatrics Society Annual Meeting, using anonymous audience response system technology as well as verbal and written feedback.
Results
High-quality evidence based on patient-oriented outcomes was insufficient or non-existent for all three domains. The participatory audiences did not reach a consensus on any of the proposed QIs. Key research questions for medication management (3), screening and prevention (2), and functional assessment (3) are presented based upon proposed QIs that the majority of participants accepted.
Conclusions
In assessing a minimal standard of care by which to systematically derive geriatric QIs for medication management, screening and prevention, and functional assessment, compelling clinical research evidence is lacking. Patient-oriented research questions that are essential to justify and characterize future quality indicators within these domains are described.

10.  Four Sensitive Screening Tools to Detect Cognitive Dysfunction in Geriatric Emergency Department Patients: Brief Alzheimer’s Screen, Short Blessed Test, Ottawa 3DY, and the Caregiver-completed AD8 
Background
Cognitive dysfunction, including dementia and delirium, is prevalent in geriatric emergency department (ED) patients, but often remains undetected. One barrier to reliable identification of acutely or chronically impaired cognitive function is the lack of an acceptable screening tool. While multiple brief screening instruments have been derived, ED validation trials have not previously demonstrated tools that are appropriately sensitive for clinical use.
Objectives
The primary objective was to evaluate and compare the Ottawa 3DY (O3DY), Brief Alzheimer’s Screen (BAS), Short Blessed Test (SBT), and caregiver-completed AD8 (cAD8) diagnostic test performance for cognitive dysfunction in geriatric ED patients using the Mini Mental Status Exam (MMSE) as the criterion standard. A secondary objective was to assess the diagnostic accuracy for the cAD8 (which is an informant-based instrument) when used in combination with the other performance-based screening tools.
Methods
In an observational cross-sectional cohort study at one urban academic university-affiliated medical center, trained research assistants collected patients’ responses on the Confusion Assessment Method for the Intensive Care Unit, BAS, and SBT. When available, reliable caregivers completed the cAD8. The MMSE was then obtained. The O3DY was reconstructed from elements of the MMSE and the BAS. Consenting subjects were non-critically ill, English-speaking adults over age 65 years, who had not received potentially sedating medications prior to or during cognitive testing. Using an MMSE score ≤ 23 as the criterion standard for cognitive dysfunction, the sensitivity, specificity, likelihood ratios, and receiver operating characteristic area under the curve were computed. Venn diagrams were constructed to quantitatively compare the degree of overlap among positive test results between the performance-based instruments.
Results
The prevalence of cognitive dysfunction for the 163 patients enrolled with complete data collection was 37%, including 5.5% with delirium. Dementia was self-reported in 3%. Caregivers were available to complete the cAD8 for 56% of patients. The SBT, BAS, and O3DY each demonstrated 95% sensitivity, compared with 83% sensitivity for the cAD8. The SBT had a superior specificity of 65%. No combination of instruments with the cAD8 significantly improved diagnostic accuracy. The SBT provided the optimal overlap with the MMSE.
Conclusions
The SBT, BAS, and O3DY are three brief performance-based screening instruments to identify geriatric patients with cognitive dysfunction more rapidly than the MMSE. Among these three instruments, the SBT provides the best diagnostic test characteristics and overlap with MMSE results. The addition of the cAD8 to the other instruments does not enhance diagnostic accuracy.

11.  BRAIN NATRIURETIC PEPTIDE IN THE EVALUATION OF EMERGENCY DEPARTMENT DYSPNEA: IS THERE A ROLE? 
The Journal of Emergency Medicine  2011;42(2):197-205.
Background
Acute decompensated congestive heart failure (ADCHF) is a common etiology of dyspnea in emergency department (ED) patients. Delayed diagnosis of ADCHF increases morbidity and mortality. Two cardiac biomarkers, N-terminal-pro brain natriuretic peptide (NT-proBNP) and brain natriuretic peptide (BNP) have demonstrated excellent sensitivity in diagnostic accuracy studies, but the clinical impact on patient-oriented outcomes of these tests remains in question.
Clinical Question
Does emergency physician awareness of BNP or NT-proBNP level improve ADCHF patient-important outcomes including ED length of stay, hospital length of stay, cardiovascular mortality, or overall health care costs?
Evidence Review
Five trials have randomized clinicians to either knowledge of or no knowledge of ADCHF biomarker levels in ED patients with dyspnea and some suspicion for heart failure. In assessing patient-oriented outcomes such as length-of-stay, return visits, and overall health care costs, the randomized controlled trials fail to provide evidence of unequivocal benefit to patients, clinicians, or society.
Conclusion
Clinician awareness of BNP or NT-proBNP levels in ED dyspnea patients does not necessarily improve outcomes. Future ADCHF biomarker trials must assess patient-oriented outcomes in conjunction with validated risk-stratification instruments.

12.  Evidence-based Diagnostics: Adult Septic Arthritis 
Background
Acutely swollen or painful joints are common complaints in the emergency department (ED). Septic arthritis in adults is a challenging diagnosis, but prompt differentiation of a bacterial etiology is crucial to minimize morbidity and mortality.
Objectives
The objective was to perform a systematic review describing the diagnostic characteristics of history, physical examination, and bedside laboratory tests for nongonococcal septic arthritis. A secondary objective was to quantify test and treatment thresholds using derived estimates of sensitivity and specificity, as well as best-evidence diagnostic and treatment risks and anticipated benefits from appropriate therapy.
Methods
Two electronic search engines (PUBMED and EMBASE) were used in conjunction with a selected bibliography and scientific abstract hand search. Inclusion criteria included adult trials of patients presenting with monoarticular complaints if they reported sufficient detail to reconstruct partial or complete 2 × 2 contingency tables for experimental diagnostic test characteristics using an acceptable criterion standard. Evidence was rated by two investigators using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS). When more than one similarly designed trial existed for a diagnostic test, meta-analysis was conducted using a random effects model. Interval likelihood ratios (LRs) were computed when possible. To illustrate one method to quantify theoretical points in the probability of disease whereby clinicians might cease testing altogether and either withhold treatment (test threshold) or initiate definitive therapy in lieu of further diagnostics (treatment threshold), an interactive spreadsheet was designed and sample calculations were provided based on research estimates of diagnostic accuracy, diagnostic risk, and therapeutic risk/benefits.
Results
The prevalence of nongonococcal septic arthritis in ED patients with a single acutely painful joint is approximately 27% (95% confidence interval [CI] = 17% to 38%). With the exception of joint surgery (positive likelihood ratio [+LR] = 6.9) or skin infection overlying a prosthetic joint (+LR = 15.0), history, physical examination, and serum tests do not significantly alter posttest probability. Serum inflammatory markers such as white blood cell (WBC) counts, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) are not useful acutely. The interval LR for synovial white blood cell (sWBC) counts of 0 × 109–25 × 109/ L was 0.33; for 25 × 109–50 × 109/L, 1.06; for 50 × 109–100 × 109/L, 3.59; and exceeding 100 × 109/L, infinity. Synovial lactate may be useful to rule in or rule out the diagnosis of septic arthritis with a +LR ranging from 2.4 to infinity, and negative likelihood ratio (−LR) ranging from 0 to 0.46. Rapid polymerase chain reaction (PCR) of synovial fluid may identify the causative organism within 3 hours. Based on 56% sensitivity and 90% specificity for sWBC counts of >50 × 109/L in conjunction with best-evidence estimates for diagnosis-related risk and treatment-related risk/benefit, the arthrocentesis test threshold is 5%, with a treatment threshold of 39%.
Conclusions
Recent joint surgery or cellulitis overlying a prosthetic hip or knee were the only findings on history or physical examination that significantly alter the probability of nongonococcal septic arthritis. Extreme values of sWBC (>50 × 109/L) can increase, but not decrease, the probability of septic arthritis. Future ED-based diagnostic trials are needed to evaluate the role of clinical gestalt and the efficacy of nontraditional synovial markers such as lactate.

13.  Development of Geriatric Competencies for Emergency Medicine Residents Using an Expert Consensus Process 
Background
The emergency department (ED) visit rate for older patients exceeds that of all age groups other than infants. The aging population will increase elder ED patient utilization to 35% to 60% of all visits. Older patients can have complex clinical presentations and be resource-intensive. Evidence indicates that emergency physicians fail to provide consistent high-quality care for elder ED patients, resulting in poor clinical outcomes.
Objectives
The objective was to develop a consensus document, “Geriatric Competencies for Emergency Medicine Residents,” by identified experts. This is a minimum set of behaviorally based performance standards that all residents should be able to demonstrate by completion of their residency training.
Methods
This consensus-based process utilized an inductive, qualitative, multiphase method to determine the minimum geriatric competencies needed by emergency medicine (EM) residents. Assessments of face validity and reliability were used throughout the project.
Results
In Phase I, participants (n = 363) identified 12 domains and 300 potential competencies. In Phase II, an expert panel (n = 24) clustered the Phase I responses, resulting in eight domains and 72 competencies. In Phase III, the expert panel reduced the competencies to 26. In Phase IV, analysis of face validity and reliability yielded a 100% consensus for eight domains and 26 competencies. The domains identified were atypical presentation of disease; trauma, including falls; cognitive and behavioral disorders; emergent intervention modifications; medication management; transitions of care; pain management and palliative care; and effect of comorbid conditions.
Conclusions
The Geriatric Competencies for EM Residents is a consensus document that can form the basis for EM residency curricula and assessment to meet the demands of our aging population.

14.  Incorporating Evidence-based Medicine into Resident Education: A CORD Survey of Faculty and Resident Expectations 
Background
The Accreditation Council for Graduate Medical Education (ACGME) invokes evidence-based medicine (EBM) principles through the practice-based learning core competency. The authors hypothesized that among a representative sample of emergency medicine (EM) residency programs, a wide variability in EBM resident training priorities, faculty expertise expectations, and curricula exists.
Objectives
The primary objective was to obtain descriptive data regarding EBM practices and expectations from EM physician educators. Our secondary objective was to assess differences in EBM educational priorities among journal club directors compared with non–journal club directors.
Methods
A 19-question survey was developed by a group of recognized EBM curriculum innovators and then disseminated to Council of Emergency Medicine Residency Directors (CORD) conference participants, assessing their opinions regarding essential EBM skill sets and EBM curricular expectations for residents and faculty at their home institutions. The survey instrument also identified the degree of interest respondents had in receiving a free monthly EBM journal club curriculum.
Results
A total of 157 individuals registered for the conference, and 98 completed the survey. Seventy-seven (77% of respondents) were either residency program directors or assistant / associate program directors. The majority of participants were from university-based programs and in practice at least 5 years. Respondents reported the ability to identify flawed research (45%), apply research findings to patient care (43%), and comprehend research methodology (33%) as the most important resident skill sets. The majority of respondents reported no formal journal club or EBM curricula (75%) and do not utilize structured critical appraisal instruments (71%) when reviewing the literature. While journal club directors believed that resident learners’ most important EBM skill is to identify secondary peer-reviewed resources, non–journal club directors identified residents’ ability to distinguish significantly flawed research as the key skill to develop. Interest in receiving a free monthly EBM journal club curriculum was widely accepted (89%).
Conclusions
Attaining EBM proficiency is an expected outcome of graduate medical education (GME) training, although the specific domains of anticipated expertise differ between faculty and residents. Few respondents currently use a formalized curriculum to guide the development of EBM skill sets. There appears to be a high level of interest in obtaining EBM journal club educational content in a structured format. Measuring the effects of providing journal club curriculum content in conjunction with other EBM interventions may warrant further investigation.

16.  THROMBOLYTIC THERAPY FOR ACUTE ISCHEMIC STROKE BEYOND THREE HOURS 
Background
Ischemic cerebrovascular accidents remain a leading cause of morbidity and mortality. Thrombolytic therapy for acute ischemic stroke within 3 h of symptom onset of highly select patients has been advocated by some groups since 1995, but trials have yielded inconsistent outcomes. One recent trial demonstrated significant improvement when the therapeutic window was extended to 4.5 h.
Clinical Question
Does the intravenous systemic administration of tPA within 4.5 h to select patients with acute ischemic stroke improve functional outcomes?
Evidence Review
All randomized controlled trials enrolling patients within 4.5 h were identified, in addition to a meta-analysis of these trial data.
Results
The National Institute of Neurological Disorders and Stroke (NINDS) and European Cooperative Acute Stroke Study III (ECASS III) clinical trials demonstrated significantly improved outcomes at 3 months, with increased rates of intracranial hemorrhage, whereas ECASS II and the Acute Noninterventional Therapy in Ischemic Stroke (ATLANTIS) study showed increased hemorrhagic complications without improving outcomes. Meta-analysis of trial data from all ECASS trials, NINDS, and ATLANTIS suggest that thrombolysis within 4.5 h improves functional outcomes.
Conclusion
Ischemic stroke tPA treatment within 4.5 h seems to improve functional outcomes and increases symptomatic intracranial hemorrhage rates without significantly increas ing mortality.

18.  Physician and Nurse Acceptance of Technicians to Screen for Geriatric Syndromes in the Emergency Department 
Introduction
The objective of this study was to evaluate emergency medicine physician and nurse acceptance of nonnurse, nonphysician screening for geriatric syndromes.
Methods
This was a single-center emergency department (ED) survey of physicians and nurses after an 8-month project. Geriatric technicians were paid medical student research assistants evaluating consenting ED patients older than 65 years for cognitive dysfunction, fall risk, or functional decline. The primary objective of this anonymous survey was to evaluate ED nurse and physician perceptions about the geriatric screener feasibility and barriers to implementation. In addition, as a secondary objective, respondents reported ongoing geriatric screening efforts independent of the research screeners.
Results
The survey was completed by 72% of physicians and 33% of nurses. Most nurses and physicians identified geriatric technicians as beneficial to patients without impeding ED throughput. Fewer than 25% of physicians routinely screen for any geriatric syndromes. Nurses evaluated for fall risk significantly more often than physicians, but no other significant differences were noted in ongoing screening efforts.
Conclusion
Dedicated geriatric technicians are perceived by nurses and physicians as beneficial to patients with the potential to improve patient safety and clinical outcomes. Most nurses and physicians are not currently screening for any geriatric syndromes.

20.  Antibiotic prophylaxis for urinary tract infections after removal of urinary catheter: meta-analysis 
Objective To determine whether antibiotic prophylaxis at the time of removal of a urinary catheter reduces the risk of subsequent symptomatic urinary tract infection.
Design Systematic review and meta-analysis of studies published before November 2012 identified through PubMed, Embase, Scopus, and the Cochrane Library; conference abstracts for 2006-12 were also reviewed.
Inclusion criteria Studies were included if they examined antibiotic prophylaxis administered to prevent symptomatic urinary tract infection after removal of a short term (≤14 days) urinary catheter.
Results Seven controlled studies had symptomatic urinary tract infection after catheter removal as an endpoint; six were randomized controlled trials (five published; one in abstract form) and one was a non-randomized controlled intervention study. Five of these seven studies were in surgical patients. Studies were heterogeneous in the type and duration of antimicrobial prophylaxis and the period of observation. Overall, antibiotic prophylaxis was associated with benefit to the patient, with an absolute reduction in risk of urinary tract infection of 5.8% between intervention and control groups. The risk ratio was 0.45 (95% confidence interval 0.28 to 0.72). The number needed to treat to prevent one urinary tract infection was 17 (12 to 30).
Conclusions Patients admitted to hospital who undergo short term urinary catheterization might benefit from antimicrobial prophylaxis when the catheter is removed as they experience fewer subsequent urinary tract infections. Potential disadvantages of more widespread antimicrobial prophylaxis (side effects and cost of antibiotics, development of antimicrobial resistance) might be mitigated by the identification of which patients are most likely to benefit from this approach.

21.  A mixed methods multiple case study of implementation as usual in children’s social service organizations: study protocol 
Background
Improving quality in children’s mental health and social service settings will require implementation strategies capable of moving effective treatments and other innovations (e.g., assessment tools) into routine care. It is likely that efforts to identify, develop, and refine implementation strategies will be more successful if they are informed by relevant stakeholders and are responsive to the strengths and limitations of the contexts and implementation processes identified in usual care settings. This study will describe: the types of implementation strategies used; how organizational leaders make decisions about what to implement and how to approach the implementation process; organizational stakeholders’ perceptions of different implementation strategies; and the potential influence of organizational culture and climate on implementation strategy selection, implementation decision-making, and stakeholders’ perceptions of implementation strategies.
Methods/design
This study is a mixed methods multiple case study of seven children’s social service organizations in one Midwestern city in the United States that compose the control group of a larger randomized controlled trial. Qualitative data will include semi-structured interviews with organizational leaders (e.g., CEOs/directors, clinical directors, program managers) and a review of documents (e.g., implementation and quality improvement plans, program manuals, etc.) that will shed light on implementation decision-making and specific implementation strategies that are used to implement new programs and practices. Additionally, focus groups with clinicians will explore their perceptions of a range of implementation strategies. This qualitative work will inform the development of a Web-based survey that will assess the perceived effectiveness, relative importance, acceptability, feasibility, and appropriateness of implementation strategies from the perspective of both clinicians and organizational leaders. Finally, the Organizational Social Context measure will be used to assess organizational culture and climate. Qualitative, quantitative, and mixed methods data will be analyzed and interpreted at the case level as well as across cases in order to highlight meaningful similarities, differences, and site-specific experiences.
Discussion
This study is designed to inform efforts to develop more effective implementation strategies by fully describing the implementation experiences of a sample of community-based organizations that provide mental health services to youth in one Midwestern city.
