Identifying Strategies to Reduce Low-Value Preoperative Testing for Low-Risk Procedures: a Qualitative Study of Facilities with High or Recently Improved Levels of Testing.

BACKGROUND: Healthcare agencies and perioperative professional organizations recommend avoiding preoperative screening tests for low-risk surgical procedures. However, low-value preoperative tests are still commonly ordered even for generally healthy patients and active strategies to reduce this testing have not been adequately described. OBJECTIVE: We sought to learn from hospitals with either high levels of testing or that had recently reduced use of low-value screening tests (aka "delta sites") about reasons for testing and active deimplementation strategies they used to effectively improve practice. DESIGN: Qualitative study of semi-structured telephone interviews. PARTICIPANTS: We identified facilities in the US Veterans Health Administration (VHA) with high or recently improved burden of potentially low-value preoperative testing for carpal tunnel release and cataract surgery. We recruited perioperative clinicians to participate. APPROACH: Questions focused on reasons to order preoperative screening tests for patients undergoing low-risk surgery and, more importantly, what strategies had been successfully used to reduce testing. A framework method was used to identify common improvement strategies and specific care delivery innovations. KEY RESULTS: Thirty-five perioperative clinicians (e.g., hand surgeons, ophthalmologists, anesthesiologists, primary care providers, directors of preoperative clinics, nurses) from 29 VHA facilities participated. Facilities that successfully reduced the burden of low-value testing shared many improvement strategies (e.g., building consensus among stakeholders; using evidence/norm-based education and persuasion; clarifying responsibility for ordering tests) to implement different care delivery innovations (e.g., pre-screening to decide if a preop clinic evaluation is necessary; establishing a dedicated preop clinic for low-risk procedures). CONCLUSIONS: We identified a menu of common improvement strategies and specific care delivery innovations that might be helpful for institutions trying to design their own quality improvement programs to reduce low-value preoperative testing given their unique structure, resources, and constraints.

Can Machine Learning Methods Produce Accurate and Easy-to-Use Preoperative Prediction Models of One-Year Improvements in Pain and Functioning After Knee Arthroplasty?

BACKGROUND: Approximately 15%-20% of total knee arthroplasty (TKA) patients do not experience clinically meaningful improvements. We sought to compare the accuracy and parsimony of several machine learning strategies for developing predictive models of failing to experience minimal clinically important differences in patient-reported outcome measures (PROMs) 1 year after TKA. METHODS: Patients (N = 587) in 3 large Veteran Health Administration facilities completed PROMs before and 1 year after TKA (92% follow-up). Preoperative PROMs and electronic health record data were used to develop and validate models to predict failing to experience at least a minimal clinically important difference in Knee Injury and Osteoarthritis Outcome Score (KOOS) Total, KOOS JR, and KOOS subscales (Pain, Symptoms, Activities of Daily Living, Quality of Life, and recreation). Several machine learning strategies were used for model development. Ten-fold cross-validation and bootstrapping were used to produce measures of overall accuracy (C-statistic, Brier Score). The sensitivity and specificity of various predicted probability cut-points were examined. RESULTS: The most accurate models produced were for the Activities of Daily Living, Pain, Symptoms, and Quality of Life subscales of the KOOS (C-statistics 0.76, 0.72, 0.72, and 0.71, respectively). Strategies varied substantially in terms of the numbers of inputs required to achieve similar accuracy, with none being superior for all outcomes. CONCLUSION: Models produced in this project provide estimates of patient-specific improvements in major outcomes 1 year after TKA. Integrating these models into clinical decision support, informed consent and shared decision making could improve patient selection, education, and satisfaction. LEVEL OF EVIDENCE: Level III, diagnostic study.

Comparing Methods to Determine the Minimal Clinically Important Differences in Patient-Reported Outcome Measures for Veterans Undergoing Elective Total Hip or Knee Arthroplasty in Veterans Health Administration Hospitals.

Importance: The minimal clinically important difference (MCID) in a patient-reported outcome measure (PROM) is the smallest change that patients perceive as beneficial. Accurate MCIDs are required when PROMs are used to evaluate the value of surgical interventions. Objective: To use well-defined distribution-based and anchor-based methods to calculate MCIDs in the Hip Disability and Osteoarthritis Outcome Score (HOOS) and in the Knee Injury and Osteoarthritis Outcome Score (KOOS) for veterans undergoing primary total hip arthroplasty or total knee arthroplasty. Design, Setting, and Participants: A prospective cohort study was conducted of 858 patients undergoing total joint replacement between March 16, 2015, and March 9, 2017, at 3 high-complexity Veterans Affairs Medical Centers. Interventions: Patients undergoing total hip arthroplasty or total knee arthroplasty were administered HOOS or KOOS PROMs prior to and 1 year after surgery. The Self-Administered Patient Satisfaction Scale (SAPS) for primary hip or knee arthroplasty was administered at 1-year follow-up as an anchor PROM. Main Outcomes and Measures: The HOOS and KOOS before and 1 year after surgery, change scores (difference between postoperative and preoperative PROM scores), and MCIDs for each measure. For anchor-based methods, receiver operating characteristic curve analysis was performed, including calculation of the area under the curve. Results: The mean (SD) age of the 271 patients who underwent hip arthroplasty was 65.6 (8.3) years, and the mean (SD) age of the 587 patients who underwent knee arthroplasty was 66.1 (8.2) years. There were 547 men in the knee arthroplasty cohort and 256 men in the hip arthroplasty cohort (total, 803 men). There were significant improvements in the mean values of every PROM, with mean (SD) differences greater than 39 for HOOS Joint Replacement (JR) and every hip subscale (HOOS JR, 39.7 [20.2]; pain, 47.6 [20.5]; symptoms, 45.1 [21.5]; activities of daily living, 43.7 [22.1]; recreation, 49.2 [33.5]; quality of life, 50.3 [27.8]) and mean (SD) differences greater than 29 for KOOS JR and every knee subscale (KOOS JR, 30.4 [17.5]; pain, 38.0 [20.4]; symptoms, 29.5 [22.1]; activities of daily living, 34.8 [20.5]; recreation, 34.6 [31.1]; quality of life, 35.2 [26.8]). Different calculation methods yielded a wide range of MCIDs. Distribution-based approaches tended to give lower values than the anchor-based approaches, which gave similar values for most PROMs. Area under the curve values demonstrated good to excellent discrimination for SAPS for nearly all PROMs. Conclusions and Relevance: Minimal clinically important difference estimates can be highly variable depending on the method used. Patient satisfaction measured by SAPS is a suitable anchor for the HOOS and KOOS. This study suggests that the SAPS-anchored MCID values presented here be used in future studies of total hip arthroplasty and total knee arthroplasty for veterans.

Reducing Frequent Utilization of Psychiatric Emergency Services Among Veterans While Maintaining Quality of Care.

OBJECTIVE: Use of psychiatric emergency services in emergency departments (EDs) and inpatient psychiatry units contributes substantially to the cost of mental health care. Among patients who utilize psychiatric emergency services, a small percentage ("high utilizers") contributes a disproportionate share of the total cost, yet little is known about the context of care for these patients. This study employed qualitative methods to identify barriers to and facilitators of reducing use of psychiatric emergency services among high utilizers. METHODS: Semistructured phone interviews were conducted with 31 directors of mental health services and providers of psychiatric emergency services across 22 Veterans Health Administration medical centers. The Consolidated Framework for Implementation Research was used to guide the interviews to evaluate the context of care for high utilizers. Thematic coding was used to identify barriers to and facilitators of reducing utilization. RESULTS: Barriers emerged at the patient level (for example, treatment nonadherence and transiency), provider level (for example, stigma toward high utilizers and lack of expertise and training in the management of psychiatric issues among ED staff), and system level (for example, lack of specialized services to address short- and long-term care needs). Facilitators included recovery-oriented care; interdisciplinary care coordination and case management, with emphasis on the role of psychiatric social workers; and predictive analytics to flag high utilizers. CONCLUSIONS: The findings lay the groundwork for the design of novel approaches to care for high utilizers of psychiatric emergency services while limiting provider burnout, managing costs, and optimizing treatment outcomes.

Cognitive-behavioral treatments for criminogenic thinking: Barriers and facilitators to implementation within the Veterans Health Administration.

Cognitive-behavioral treatments for criminogenic thinking (i.e., antisocial cognitions, attitudes, and traits) are regarded as best practices for reducing criminal recidivism among justice-involved adults. However, the barriers and facilitators to implementation of these treatments within large health care systems such as the Veterans Health Administration (VHA) are largely unknown. To address this gap, we conducted qualitative interviews with 22 Specialists from the VHA's Veterans Justice Programs who had been trained in a cognitive-behavioral treatment for criminogenic thinking (i.e., Moral Reconation Therapy [MRT], Thinking for a Change [T4C]). The time-intensiveness of these treatments emerged as a barrier to implementation. Potential solutions identified were patient incentives for treatment engagement, streamlining the curriculum, and implementing the treatments within long-term/residential programs. At the program level, providers' stigma/bias toward patients with antisocial tendencies was seen as a barrier to implementation, as were time/resource constraints on providers. To address the latter, use of peer providers to deliver the treatments and partnerships between justice programs and behavioral health services were suggested. At the system level, lack of recognition of criminogenic treatments as evidence based, and uncertainty of sustained funds to support ongoing costs of these treatments emerged as implementation barriers. To address the latter, a train-the-trainers model was suggested. Our findings serve as a guide for implementation of criminogenic treatments for providers and policymakers in VHA and other large health care systems, which are increasingly called upon to provide care to justice-involved adults in the community.

VA residential substance use disorder treatment program providers' perceptions of facilitators and barriers to performance on pre-admission processes.

BACKGROUND: In the U.S. Department of Veterans Affairs (VA), residential treatment programs are an important part of the continuum of care for patients with a substance use disorder (SUD). However, a limited number of program-specific measures to identify quality gaps in SUD residential programs exist. This study aimed to: (1) Develop metrics for two pre-admission processes: Wait Time and Engagement While Waiting, and (2) Interview program management and staff about program structures and processes that may contribute to performance on these metrics. The first aim sought to supplement the VA's existing facility-level performance metrics with SUD program-level metrics in order to identify high-value targets for quality improvement. The second aim recognized that not all key processes are reflected in the administrative data, and even when they are, new insight may be gained from viewing these data in the context of day-to-day clinical practice. METHODS: VA administrative data from fiscal year 2012 were used to calculate pre-admission metrics for 97 programs (63 SUD Residential Rehabilitation Treatment Programs (SUD RRTPs); 34 Mental Health Residential Rehabilitation Treatment Programs (MH RRTPs) with a SUD track). Interviews were then conducted with management and front-line staff to learn what factors may have contributed to high or low performance, relative to the national average for their program type. We hypothesized that speaking directly to residential program staff may reveal innovative practices, areas for improvement, and factors that may explain system-wide variability in performance. RESULTS: Average wait time for admission was 16 days (SUD RRTPs: 17 days; MH RRTPs with a SUD track: 11 days), with 60% of Veterans waiting longer than 7 days. For these Veterans, engagement while waiting occurred in an average of 54% of the waiting weeks (range 3-100% across programs). Fifty-nine interviews representing 44 programs revealed factors perceived to potentially impact performance in these domains. Efficient screening processes, effective patient flow, and available beds were perceived to facilitate shorter wait times, while lack of beds, poor staffing levels, and lengths of stay of existing patients were thought to lengthen wait times. Accessible outpatient services, strong patient outreach, and strong encouragement of pre-admission outpatient treatment emerged as facilitators of engagement while waiting; poor staffing levels, socioeconomic barriers, and low patient motivation were viewed as barriers. CONCLUSIONS: Metrics for pre-admission processes can be helpful for monitoring residential SUD treatment programs. Interviewing program management and staff about drivers of performance metrics can play a complementary role by identifying innovative and other strong practices, as well as high-value targets for quality improvement. Key facilitators of high-performing facilities may offer programs with lower performance useful strategies to improve specific pre-admission processes.

Factors associated with emergency department useamong veteran psychiatric patients.

Frequent utilization of emergency department (ED) services contributes substantially to the cost of healthcare nationally and is often driven by psychiatric factors. Using national-level data from the Veterans Health Administration (VHA), the present study examined patient-level factors associated with ED use among veteran psychiatric patients. Veterans who had at least one ED visit with a psychiatric diagnosis in fiscal years 2011-2012 (n = 226,122) were identified in VHA administrative records. Andersen's behavioral model of healthcare utilization was used to identify need, enabling, and predisposing factors associated with frequency of ED use (primary outcome) in multivariate regression models. Greater ED use was primarily linked with need (psychotic, anxiety, personality, substance use, and bipolar disorders) and enabling (detoxification-related service utilization and homelessness) factors. Chronic medical conditions, receipt of an opioid prescription, and predisposing factors (e.g., younger age) were also linked to greater ED use; however, the effect sizes for these factors were markedly lower than those of most psychiatric and psychosocial factors. The findings suggest that intensive case management programs aimed reducing frequent ED use among psychiatric patients may require greater emphasis on homelessness and other psychosocial deficits that are common among these patients, and future research should explore cost-effective approaches to implementing these programs.

The Availability and Utility of Services to Address Risk Factors for Recidivism among Justice-Involved Veterans.

The availability and utility of services to address recidivism risk factors among justice-involved veterans is unknown. We explored these issues through qualitative interviews with 63 Specialists from the Department of Veterans Affairs' (VA) Veterans Justice Programs. To guide the interviews, we utilized the Risk-Need-Responsivity (RNR) model of offender rehabilitation. Specialists reported that justice-involved veterans generally have access to services to address most RNR-based risk factors (substance abuse; lack of positive school/work involvement; family/marital dysfunction; lack of prosocial activities/interests), but have less access to services targeting risk factors of antisocial tendencies and associates and empirically-based treatments for recidivism in VA. Peer-based services, motivational interviewing/cognitive-behavioral therapy, and Veterans Treatment Courts were perceived as useful to address multiple risk factors. These findings highlight potential gaps in provision of evidence-based care to address recidivism among justice-involved veterans, as well as promising policy-based solutions that may have widespread impact on reducing recidivism in this population.

Effectiveness of full agonist opioids in patients stabilized on buprenorphine undergoing major surgery: a case series.

A review of the medical literature failed to reveal clear, agreed-upon guidelines for practitioners on the postoperative provision of full agonist opioids for patients maintained on buprenorphine. Some controversy appears to exist about whether to maintain patients on their buprenorphine regimen up to the time of surgery. We describe the surgical outcomes and pain assessments for a series of five patients who underwent seven major surgical procedures. The patients were maintained on stable doses of sublingual buprenorphine. Postoperative pain was adequately controlled using full agonist opioids according to self-report and physician assessment. The observations from this case series lend support to the practice of maintaining stable buprenorphine dosing for patients who require major surgery.

Rural jail telepsychiatry: a pilot feasibility study.

New York State has a large rural population, and many of the jails in rural areas have minimal or no psychiatric services available on site. Cost of transport to off-site psychiatric services and the safety issues related to moving inmates from a secure building may limit inmate access to appropriate psychiatric services. This feasibility study describes a project that provided telepsychiatric consultation to increase access to psychiatric treatment in an underserved rural jail in upstate New York. Subjects were consenting jail inmates who requested or were found to be in need of psychiatric care. The project provided interactive two-way audio-video communication between the psychiatrist located in an urban university medical center and subjects who were incarcerated 182 miles away. During the project period, 15 inmates were assessed and treated in 37 consultations. Subjects were predominantly young white males with anxiety, mood, and substance use disorders. Services were readily accepted by inmates and staff. Telepsychiatric examination and treatment appears to be a feasible method to increase access to mental health care in rural jails. Future advocacy for increased mental health services in rural areas in criminal justice setting is likely to depend on further evidence of favorable cost benefit.
