Women's Wellness Through Equity and Leadership (WEL): A Program Evaluation.

BACKGROUND AND OBJECTIVES: The Women's Wellness through Equity and Leadership (WEL) program was developed as a collaboration between 6 major medical associations in the United States. The goal was to contribute to the creation of equitable work environments for women physicians. The purpose of the current study was to evaluate the pilot implementation of WEL. METHODS: Participants included a diverse group of 18 early career to midcareer women physicians from across medical specialties, 3 from each partner organization. WEL was developed as an 18-month program with 3 series focused on wellness, equity, and leadership and included monthly virtual and in-person meetings. After institutional board review approval, a mixed-methods evaluation design was incorporated, which included postseries and postprogram surveys and in-depth telephone interviews. RESULTS: Participants delineated several drivers of program success, including peer support and/or networks; interconnectedness between the topics of wellness, equity, and leadership; and diversity of participants and faculty. Areas for improvement included more opportunities to connect with peers and share progress and more structured mentorship. Regarding program impact, participants reported increased knowledge and behavior change because of their participation. CONCLUSIONS: This longitudinal, cohort initiative resulted from a successful collaboration between 6 medical associations. Evaluation findings suggest that providing opportunities for women physicians to connect with and support each other while building knowledge and skills can be an effective way to advance wellness, equity, and leadership for women in medicine.

Implementing Common Metrics across the NIH Clinical and Translational Science Awards (CTSA) consortium.

The Clinical and Translational Science Award (CTSA) Consortium and the National Center for Advancing Translational Science (NCATS) undertook a Common Metrics Initiative to improve research processes across the national CTSA Consortium. This was implemented by Tufts Clinical and Translational Science Institute at the 64 CTSA academic medical centers. Three metrics were collaboratively developed by NCATS staff, CTSA Consortium teams, and outside consultants for Institutional Review Board Review Duration, Careers in Clinical and Translational Research, and Pilot Award Publications and Subsequent Funding. The implementation program included training on the metric operational guidelines, data collection, data reporting system, and performance improvement framework. The implementation team provided small-group coaching and technical assistance. Collaborative learning sessions, driver diagrams, and change packages were used to disseminate best and promising practices. After 14 weeks, 84% of hubs had produced a value for one metric and about half had produced an initial improvement plan. Overall, hubs reported that the implementation activities facilitated their Common Metrics performance improvement process. Experiences implementing the first three metrics can inform future directions of the Common Metrics Initiative and other research groups implementing standardized metrics and performance improvement processes, potentially including other National Institutes of Health institutes and centers.

Pilot test of an accrual Common Metric for the NIH Clinical and Translational Science Awards (CTSA) Consortium: Metric feasibility and data quality.

Failure to accrue participants into clinical trials incurs economic costs, wastes resources, jeopardizes answering research questions meaningfully, and delays translating research discoveries into improved health. This paper reports the results of a pilot test of the Median Accrual Ratio (MAR) metric developed as a part of the Common Metrics Initiative of the NIH's National Center for Advancing Translational Science (NCATS) Clinical and Translational Science Award (CTSA) Consortium. Using the metric is intended to enhance the ability of the CTSA Consortium and its "hubs" to increase subject accrual into trials within expected timeframes. The pilot test was undertaken at Tufts Clinical and Translational Science Institute (CTSI) with eight CTSA Consortium hubs. We describe the pilot test methods, and results regarding feasibility of collecting metric data and the quality of data that was collected. Participating hubs welcomed the opportunity to assess accrual efforts, but experienced challenges in collecting accrual metric data due to insufficient infrastructure and inconsistent implementation of electronic data systems and lack of uniform data definitions. Also, the metric could not be constructed for all trial designs, particularly those using competitive enrollment strategies. We offer recommendations to address the identified challenges to facilitate progress to broad accrual metric data collection and use.

Pilot test of an accrual Common Metric for the NIH Clinical and Translational Science Awards (CTSA) Consortium: Metric usefulness.

The Common Metrics Initiative aims to develop and field metrics to improve research processes within the national Clinical and Translational Science Award (CTSA) Consortium. A Median Accrual Ratio (MAR) common metric was developed to assess the results of efforts to increase subject accrual into a set of clinical trials within the expected time period. A pilot test of the MAR was undertaken at Tufts Clinical and Translational Science Institute (CTSI) with eight CTSA Consortium hubs. Post-pilot interviews were conducted with 9 CTSA Principal Investigators (PIs) and 23 pilot team members. Over three-quarters (78%) of respondents reported that the MAR could be useful for performance improvement, but also described limitations or concerns. The most commonly cited barrier to MAR use for performance improvement was difficulty in interpreting the single value that is produced. Most respondents were interested in using the MAR to assess recruitment at an individual trial level. Majority of respondents (63%) had mixed opinions about aggregating metric results across the CTSA Consortium for comparison or benchmarking. Collecting data about additional contextual factors, and comparing accrual between subgroups, were cited as potentially helping address concerns about aggregation. Significant challenges remain in ensuring that the MAR can be sufficiently useful for collaborative process improvement. We offer recommendations to potentially improve metric usefulness.

A hindbrain inhibitory microcircuit mediates vagally-coordinated glucose regulation.

Neurons in the brainstem dorsal vagal complex integrate neural and humoral signals to coordinate autonomic output to viscera that regulate a variety of physiological functions, but how this circuitry regulates metabolism is murky. We tested the hypothesis that premotor, GABAergic neurons in the nucleus tractus solitarius (NTS) form a hindbrain micro-circuit with preganglionic parasympathetic motorneurons of the dorsal motor nucleus of the vagus (DMV) that is capable of modulating systemic blood glucose concentration. In vitro, neuronal activation or inhibition using either excitatory or inhibitory designer receptor exclusively activated by designer drugs (DREADDs) constructs expressed in GABAergic NTS neurons increased or decreased, respectively, action potential firing of GABAergic NTS neurons and downstream synaptic inhibition of the DMV. In vivo, DREADD-mediated activation of GABAergic NTS neurons increased systemic blood glucose concentration, whereas DREADD-mediated silencing of these neurons was without effect. The DREADD-induced hyperglycemia was abolished by blocking peripheral muscarinic receptors, consistent with the hypothesis that altered parasympathetic drive mediated the response. This effect was paralleled by elevated serum glucagon and hepatic phosphoenolpyruvate carboxykinase 1 (PEPCK1) expression, without affecting insulin levels or muscle metabolism. Activity in a hindbrain inhibitory microcircuit is sufficient to modulate systemic glucose concentration, independent of insulin secretion or utilization.

Co-Designing a Collaborative Chronic Care Network (C3N) for Inflammatory Bowel Disease: Development of Methods.

BACKGROUND: Our health care system fails to deliver necessary results, and incremental system improvements will not deliver needed change. Learning health systems (LHSs) are seen as a means to accelerate outcomes, improve care delivery, and further clinical research; yet, few such systems exist. We describe the process of codesigning, with all relevant stakeholders, an approach for creating a collaborative chronic care network (C3N), a peer-produced networked LHS. OBJECTIVE: The objective of this study was to report the methods used, with a diverse group of stakeholders, to translate the idea of a C3N to a set of actionable next steps. METHODS: The setting was ImproveCareNow, an improvement network for pediatric inflammatory bowel disease. In collaboration with patients and families, clinicians, researchers, social scientists, technologists, and designers, C3N leaders used a modified idealized design process to develop a design for a C3N. RESULTS: Over 100 people participated in the design process that resulted in (1) an overall concept design for the ImproveCareNow C3N, (2) a logic model for bringing about this system, and (3) 13 potential innovations likely to increase awareness and agency, make it easier to collect and share information, and to enhance collaboration that could be tested collectively to bring about the C3N. CONCLUSIONS: We demonstrate methods that resulted in a design that has the potential to transform the chronic care system into an LHS.

Perioperative Feeding Approaches in Single Ventricle Infants: A Survey of 46 Centers.

Background Feeding dysfunction occurs commonly in infants with single ventricle heart disease and impacts growth and long-term outcomes. Little evidence exists to guide safe feeding in this population. This study surveyed centers participating in the National Pediatric Cardiology Quality Improvement Collaborative to assess prevailing feeding practices amongthose caring for single ventricle neonates. Methods Web-based survey of 56 pediatric cardiac surgical centers was conducted. Questions addressed peri-operative feeding approaches and responses were presented and analyzed descriptively. Results Of 56 centers, 46 (82%) completed a survey. Preoperative feeding was common in single ventricle infants (30/46; 65%), routes varied. Centers who did not feed infants preoperatively cited the risk of necrotizing enterocolitis (16/16; 100%), presence of umbilical artery catheter (12/16; 75%), and prostaglandin infusion (9/16; 56%) as main concerns. 67% of centers reported no specific vital sign thresholds for withholding enteral feedings. In the postoperative period, most centers used an "internal guideline" (21/46; 46%) or an "informal practice" (15/46; 33%) to determine feeding readiness. Approaches to findings were significantly different among centers. About 40% of centers did not send patients home with feeding tubes, and there was no clear consensus between preferred feeding tube modality at discharge. Conclusion Considerable variation exists in feeding practices for infants with single ventricle congenital heart disease among 46 centers participating in a quality improvement collaborative. Although most centers generally feed infants preoperatively, feeding practices remain center-specific. Variability continues in the immediate post-operative and interstage periods. Further opportunities exist for investigation, standardization and development of best-practice feeding guidelines.

Digoxin Use Is Associated With Reduced Interstage Mortality in Patients With No History of Arrhythmia After Stage I Palliation for Single Ventricle Heart Disease.

BACKGROUND: Interstage mortality (IM) remains significant after stage 1 palliation (S1P) for single-ventricle heart disease (SVD), with many deaths sudden and unexpected. We sought to determine whether digoxin use post-S1P is associated with reduced IM, utilizing the multicenter database of the National Pediatric Cardiology Quality Improvement Collaborative (NPCQIC). METHODS AND RESULTS: From June 2008 to July 2013, 816 infants discharged after S1P from 50 surgical sites completed the interstage to stage II palliation, transplant, or IM. Arrhythmia during S1P hospitalization or discharge on antiarrhythmic medications were exclusions (n=270); 2 patients were lost to follow-up. Two analyses were performed: (1) propensity-score adjusted logistic regression with IM as outcome and (2) retrospective cohort analysis for patients discharged on digoxin versus not, matched for surgical site and other established IM risk factors. Of 544 study patients, 119 (21.9%) were discharged on digoxin. Logistic regression analysis with propensity score, site-size group, and digoxin use as predictor variables showed an increased risk of IM in those not discharged on digoxin (odds ratio, 8.6; lower confidence limit, 1.9; upper confidence limit, 38.3; P<0.01). The retrospective cohort analysis for 60 patients on digoxin (matched for site of care, type of S1P, post-S1P ECMO use, genetic syndrome, discharge feeding route, ventricular function, tricuspid regurgitation, and aortic arch gradient) showed 0% IM in the digoxin at discharge group and an estimated IM difference between the 2 groups of 9% (P=0.04). CONCLUSIONS: Among SVD infants in the NPCQIC database discharged post-S1P with no history of arrhythmia, use of digoxin at discharge was associated with reduced IM.

Risk Factors for Unanticipated Readmissions During the Interstage: A Report From the National Pediatric Cardiology Quality Improvement Collaborative.

This study describes unanticipated interstage readmissions in patients with hypoplastic left heart syndrome, identifies independent risk factors for unanticipated interstage readmissions, and evaluates variation in unanticipated readmission rates among collaborative centers. Retrospective data of patients enrolled in the National Pediatric Cardiology Quality Improvement Collaborative registry from July 2008 to July 2013 were analyzed. Risk factors present at the beginning of the interstage were captured. Competing risks time to event analyses determined the association between these factors and unanticipated interstage readmission. Readmission center variation was examined using funnel plots. Unanticipated interstage readmissions occurred in 66% of 815 patients at 50 centers. The median readmission length of stay was 2 days (interquartile range: 0-6) and median time to first readmission was 29 days (interquartile range: 9-63). Most readmissions were prompted by minor changes in clinical status (64%), whereas only 6% were major adverse event readmissions. Independent readmission risk factors included genetic syndrome (HR = 1.40, 95% CI: 1.05-1.88), center volume (small vs large HR = 1.32, CI: 1.04-1.66, medium vs large HR = 1.35, CI: 1.09-1.68), preoperative ventricular dysfunction (HR = 2.02, CI: 1.31-3.10), tricuspid regurgitation (HR = 1.36, CI: 1.08-1.72), duration of circulatory arrest (HR = 0.99, CI: 0.989-0.998), and undergoing Hybrid procedure relative to Norwood/right ventricle to pulmonary artery conduit (HR = 1.40, CI: 1.02-1.93). There was significant center variation in the number of readmissions and duration of readmissions. Unanticipated readmissions are common during the interstage period with notable center variation. However, these readmissions are short and are rarely in response to major adverse events.

Transparency in a Pediatric Quality Improvement Collaborative: A Passionate Journey by NPC-QIC Clinicians and Parents.

Transparency-sharing data or information about outcomes, processes, protocols, and practices-may be the most powerful driver of health care improvement. In this special article, the development and growth of transparency within the National Pediatric Cardiology Quality Improvement Collaborative is described. The National Pediatric Cardiology Quality Improvement Collaborative transparency journey is guided by equal numbers of clinicians and parents of children with congenital heart disease working together in a Transparency Work Group. Activities are organized around four interrelated levels of transparency (individual, organizational, collaborative, and system), each with a specified purpose and aim. A number of Transparency Work Group recommendations have been operationalized. Aggregate collaborative performance is now reported on the public-facing web site. Specific information that the Transparency Work Group recommends centers provide to parents has been developed and published. Almost half of National Pediatric Cardiology Quality Improvement Collaborative centers participated in a pilot of transparently sharing their outcomes achieved with one another. Individual centers have also begun successfully implementing recommended transparency activities. Despite progress, barriers to full transparency persist, including health care organization concerns about potential negative effects of disclosure on reputation and finances, and lack of reliable definitions, data, and reporting standards for fair comparisons of centers. The National Pediatric Cardiology Quality Improvement Collaborative's transparency efforts have been a journey that continues, not a single goal or destination. Balanced participation of clinicians and parents has been a critical element of the collaborative's success on this issue. Plans are in place to guide implementation of additional transparency recommendations across all four levels, including extension of the activities beyond the collaborative to support transparency efforts in national cardiology and cardiac surgery societies.

Biomarker-based asthma phenotypes of corticosteroid response.

BACKGROUND: Asthma is a heterogeneous disease with different phenotypes. Inhaled corticosteroid (ICS) therapy is a mainstay of treatment for asthma, but the clinical response to ICSs is variable. OBJECTIVE: We hypothesized that a panel of inflammatory biomarkers (ie, fraction of exhaled nitric oxide [Feno], sputum eosinophil count, and urinary bromotyrosine [BrTyr] level) might predict steroid responsiveness. METHODS: The original study from which this analysis originates comprised 2 phases: a steroid-naive phase 1 and a 28-day trial of ICSs (phase 2) during which Feno values, sputum eosinophil counts, and urinary BrTyr levels were measured. The response to ICSs was based on clinical improvements, including a 12% or greater increase in FEV1, a 0.5-point or greater decrease in Asthma Control Questionnaire score, and 2 doubling dose or greater increase in provocative concentration of adenosine 5'-monophosphate causing a 20% decrease in FEV1 (PC20AMP). Healthy control subjects were also evaluated in this study for comparison of biomarkers with those seen in asthmatic patients. RESULTS: Asthmatic patients had higher than normal Feno values, sputum eosinophil counts, and urinary BrTyr levels during the steroid-naive phase and after ICS therapy. After 28-day trial of ICSs, Feno values decreased in 82% of asthmatic patients, sputum eosinophil counts decreased in 60%, and urinary BrTyr levels decreased in 58%. Each of the biomarkers at the steroid-naive phase had utility for predicting steroid responsiveness, but the combination of high Feno values and high urinary BrTyr levels had the best power (13.3-fold, P < .01) to predict a favorable response to ICS therapy. However, the magnitude of the decrease in biomarker levels was unrelated to the magnitude of clinical response to ICS therapy. CONCLUSION: A noninvasive panel of biomarkers in steroid-naive asthmatic patients predicts clinical responsiveness to ICS therapy.

Pediatric collaborative networks for quality improvement and research.

Despite efforts of individual clinicians, pediatric practices, and institutions to remedy continuing deficiencies in pediatric safety and health care quality, multiple gaps and disparities exist. Most pediatric diseases are rare; thus, few practices or centers care for sufficient numbers of children, particularly in subspecialties, to achieve large and representative sample sizes, and substantial between-site variation in care and outcomes persists. Pediatric collaborative improvement networks are multi-site clinical networks that allow practice-based teams to learn from one another, test changes to improve quality, and use their collective experience and data to understand, implement, and spread what works in practice. The model was initially developed in 2002 by an American Board of Pediatrics Workgroup to accelerate the translation of evidence into practice, improve care and outcomes for children, and to serve as the gold standard for the performance in practice component of Maintenance of Certification requirements. Many features of an improvement network derive from the Institute for Healthcare Improvement's collaborative improvement model Breakthrough Series, including focus on a high-impact condition or topic; providing support from clinical content and quality improvement experts; using the Model for Improvement to set aims, use data for feedback, and test changes iteratively; providing infrastructure support for data collection, analysis and reporting, and quality improvement coaching; activities to enhance collaboration; and participation of multidisciplinary teams from multiple sites. In addition, they typically include a population registry of the children receiving care for the improvement topic of interest. These registries provide large and representative study samples with high-quality data that can be used to generate information and evidence, as well as to inform clinical decision making. In addition to quality improvement, networks serve as large-scale health system laboratories, providing the social, scientific, and technical infrastructure and data for multiple types of research. Statewide, regional, and national pediatric collaborative networks have demonstrated improvements in primary care practice as well as care for chronic pediatric diseases (eg, asthma, cystic fibrosis, inflammatory bowel disease, congenital heart disease), perinatal care, and patient safety (eg, central line-associated blood stream infections, adverse medication events, surgical site infections); many have documented improved outcomes. Challenges to spreading the improvement network model exist, including the need for the identification of stable funding sources. However, these barriers can be overcome, allowing the benefits of improved care and outcomes to spread to additional clinical and safety topics and care processes for the nation's children.

Prevalence and nature of adverse medical device events in hospitalized children.

Our objective was to describe the prevalence and nature of adverse medical device events (AMDEs) in tertiary care children's hospitals. In our retrospective cohort study of patients at 44 children's hospitals in the Pediatric Health Information System (PHIS), we included all inpatient stays with an AMDE-related diagnosis from January 1, 2004 to December 31, 2011. We identified AMDEs by diagnoses that specified a device in their definition. We included events present on admission as well as those complicating hospital stays. We described the characteristics of these admissions and patients, and stratified analysis by device category and presence of a complex chronic condition. Of 4,115,755 admissions in the PHIS database during the study period, 136,465 (3.3%) had at least 1 AMDE. Vascular access and nervous system devices together represented 44.4% of pediatric AMDE admissions. The majority (75.5%) of AMDE admissions were of children with complex chronic conditions. The most common age group was patients aged 2 years or less at the time of their first AMDE-related admission. AMDEs occur commonly in a population cared for in tertiary children's hospitals. Research to more specifically delineate AMDEs and their predictors are next steps to understand and improve device safety in children.

Pediatric collaborative improvement networks: background and overview.

Multiple gaps exist in health care quality and outcomes for children, who receive <50% of recommended care. The American Board of Pediatrics has worked to develop an improvement network model for pediatric subspecialties as the optimal means to improve child health outcomes and to allow subspecialists to meet the performance in practice component of Maintenance of Certification requirements. By using successful subspecialty initiatives as exemplars, and features of the Institute for Healthcare Improvement's Breakthrough Series model, currently 9 of 14 pediatric subspecialties have implemented collaborative network improvement efforts. Key components include a common aim to improve care; national multicenter prospective collaborative improvement efforts; reducing unnecessary variation by identifying, adopting, and testing best practices; use of shared, valid, high-quality real-time data; infrastructure support to apply improvement science; and public sharing of outcomes. As a key distinguisher from time-limited collaboratives, ongoing pediatric collaborative improvement networks begin with a plan to persist until aims are achieved and improvement is sustained. Additional evidence from within and external to health care has accrued to support the model since its proposal in 2002, including the Institute of Medicine's vision for a Learning Healthcare System. Required network infrastructure systems and capabilities have been delineated and can be used to accelerate the spread of the model. Pediatric collaborative improvement networks can serve to close the quality gap, engage patients and caregivers in shared learning, and act as laboratories for accelerated translation of research into practice and new knowledge discovery, resulting in improved care and outcomes for children.

Collaborative Chronic Care Networks (C3Ns) to transform chronic illness care.

Despite significant gains by pediatric collaborative improvement networks, the overall US system of chronic illness care does not work well. A new paradigm is needed: a Collaborative Chronic Care Network (C3N). A C3N is a network-based production system that harnesses the collective intelligence of patients, clinicians, and researchers and distributes the production of knowledge, information, and know-how over large groups of people, dramatically accelerating the discovery process. A C3N is a platform of "operating systems" on which interconnected processes and interventions are designed, tested, and implemented. The social operating system is facilitated by community building, engaging all stakeholders and their expertise, and providing multiple ways to participate. Standard progress measures and a robust information technology infrastructure enable the technical operating system to reduce unwanted variation and adopt advances more rapidly. A structured approach to innovation design provides a scientific operating system or "laboratory" for what works and how to make it work. Data support testing and research on multiple levels: comparative effectiveness research for populations, evaluating care delivery processes at the care center level, and N-of-1 trials and other methods to select the best treatment of individual patient circumstances. Methods to reduce transactional costs to participate include a Federated IRB Model in which centers rely on a protocol approved at 1 central institutional review board and a "commons framework" for organizational copyright and intellectual property concerns. A fully realized C3N represents a discontinuous leap to a self-developing learning health system capable of producing a qualitatively different approach to improving health.

What's in a name generator? Choosing the right name generators for social network surveys in healthcare quality and safety research.

BACKGROUND: Interest in the use of social network analysis (SNA) in healthcare research has increased, but there has been little methodological research on how to choose the name generators that are often used to collect primary data on the social connection between individuals for SNA. OBJECTIVE: We sought to determine a minimum set of name generators sufficient to distinguish the social networks of a target population of physicians active in quality improvement (QI). METHODS: We conducted a pilot survey including 8 name generators in a convenience sample of 25 physicians active in QI to characterize their social networks. We used multidimensional scaling to determine what subset of these name generators was needed to distinguish these social networks. RESULTS: We found that some physicians maintain a social network organized around a specific colleague who performed multiple roles while others maintained highly differentiated networks. We found that a set of 5 of the 8 name generators we used was needed to distinguish the networks of these physicians. CONCLUSIONS: Beyond methodology for selecting name generators, our findings suggest that QI networks may require 5 or more generators to elicit valid sets of relevant actors and relations in this target population.

Quality measures for the care of children with otitis media with effusion.

BACKGROUND: Current national efforts provide an opportunity to integrate performance measures into clinical practice and improve outcomes for children. OBJECTIVE: The goal of this study was to explore issues in developing and testing measures of care for children with otitis media with effusion (OME). METHODS: We assessed compliance with diagnostic, evaluation, and treatment measures for OME adapted from preliminary work of the Physician Consortium for Performance Improvement, using chart data in a convenience sample of practices from 2 primary care networks (Cincinnati Pediatric Research Group and the American Academy of Pediatrics Quality Improvement Innovation Network). Children aged 2 months to 12 years with at least 1 visit with a specified OME code during a 1-year period were included. RESULTS: Of 23 practices, 4 could not locate eligible visits. Nineteen practices submitted 378 abstractions (range: 3-37 per practice) with 15 identifying <30 eligible visits. Performance on diagnosis (33%) and hearing evaluation (29%) measures was low but high on measures of appropriate medication use (97% decongestant/antihistamine, 87% antibiotics, and 95% corticosteroids). Thirty-five percent of records documented antibiotic use concurrent with OME; only 16% of the 94 cases that cited reason for prescribing were appropriate. Using methods that consider appropriate clinical action, a more accurate rate for appropriate use of antibiotics was 68%. CONCLUSIONS: Coding, case finding, and evaluating appropriateness of treatment are some of the issues that will need to be considered to assess the care of children with OME. This study emphasizes the importance of testing proposed quality of care measures in "real-world" settings.

Assessment of the quality of cost analysis literature in physical therapy.

BACKGROUND: Policy makers, payers, and other stakeholders increasingly call for greater evidence of the cost-effectiveness of health care interventions. OBJECTIVE: The purposes of this study were to identify and rate the quality of cost analysis literature in physical therapy and to report summary information on the findings from the reviewed studies. DESIGN: This study was a targeted literature review and rating of relevant studies published in the last decade using a quality evaluation tool for economic studies. MEASUREMENTS: The Quality of Health Economic Studies (QHES) instrument was used to obtain quality scores. RESULTS: Ninety-five in-scope studies were identified and rated using the QHES instrument. The average quality score was 82.2 (SD=15.8), and 81 of the studies received a score of 70 or higher, placing them in the "good" to "excellent" quality range. Investigators in nearly two thirds of the studies found the physical therapy intervention under investigation to be cost-effective. LIMITATIONS: The small number of studies meeting the inclusion criteria was a limitation of the study. CONCLUSIONS: The quality of the literature regarding the cost-effectiveness of physical therapy is very good, although the magnitude of this body of literature is small. Greater awareness of the strengths and limitations of cost analyses in physical therapy should provide guidance for conducting high-quality cost-effectiveness studies as demand increases for demonstrations of the value of physical therapy.
