RESUMEN
BACKGROUND: The problem of loneliness has garnered increased attention from policymakers, payors, and providers due to higher rates during the pandemic, particularly among seniors. Prior systematic reviews have in general not been able to reach conclusions about effectiveness of interventions. METHODS: Computerized databases were searched using broad terms such as "loneliness" or "lonely" or "social isolation" or "social support" from Jan 1, 2011 to June 23, 2021. We reference mined existing systematic reviews for additional and older studies. The Social Interventions Research & Evaluation Network database and Google were searched for gray literature on Feb 4, 2022. Eligible studies were RCTs and observational studies of interventions to reduce loneliness in community-living adults that used a validated loneliness scale; studies from low- or middle-income countries were excluded, and studies were excluded if restricted to populations where all persons had the same disease (such as loneliness in persons with dementia). RESULTS: A total of 5971 titles were reviewed and 60 studies were included in the analysis, 36 RCTs and 24 observational studies. Eleven RCTs and 5 observational studies provided moderate certainty evidence that group-based treatment was associated with reduced loneliness (standardized mean difference for RCTs = - 0.27, 95% CI - 0.48, - 0.08). Five RCTs and 5 observational studies provided moderate certainty evidence that internet training was associated with reduced loneliness (standardized mean difference for RCTs = - 0.22, 95% CI - 0.30, - 0.14). Low certainty evidence suggested that group exercises may be associated with very small reductions in loneliness. Evidence was insufficient to reach conclusions about group-based activities, individual in-person interactions, internet-delivered interventions, and telephone-delivered interventions. DISCUSSION: Low-to-moderate certainty evidence exists that group-based treatments, internet training, and possibly group exercises are associated with modest reductions in loneliness in community-living older adults. These findings can inform the design of supplemental benefits and the implementation of evidence-based interventions to address loneliness.

BACKGROUND: The Veterans Health Administration (VA) serves Veterans in the nation's largest integrated healthcare system. VA seeks to provide high quality of healthcare to Veterans, but due to the VA Choice and MISSION Acts, VA increasingly pays for care outside of its system in the community. This systematic review compares care provided in VA and non-VA settings, and includes published studies from 2015 to 2023, updating 2 prior systematic reviews on this topic. METHODS: We searched PubMed, Web of Science, and PsychINFO from 2015 to 2023 for published literature comparing VA and non-VA care, including VA-paid community care. Records were included at the abstract or full-text level if they compared VA medical care with care provided in other healthcare systems, and included clinical quality, safety, access, patient experience, efficiency (cost), or equity outcomes. Data from included studies was abstracted by two independent reviewers, with disagreements resolved by consensus. Results were synthesized narratively and via graphical evidence maps. RESULTS: Thirty-seven studies were included after screening 2415 titles. Twelve studies compared VA and VA-paid community care. Most studies assessed clinical quality and safety, and studies of access were second most common. Only six studies assessed patient experience and six assessed cost or efficiency. Clinical quality and safety of VA care was better than or equal to non-VA care in most studies. Patient experience in VA care was better than or equal to experience in non-VA care in all studies, but access and cost/efficiency outcomes were mixed. DISCUSSION: VA care is consistently as good as or better than non-VA care in terms of clinical quality and safety. Access, cost/efficiency, and patient experience between the two systems are not well studied. Further research is needed on these outcomes and on services widely used by Veterans in VA-paid community care, like physical medicine and rehabilitation.

BACKGROUND: Obesity is a major threat to public health and traditional bariatric surgery continues to have low utilization. Endoscopic treatments for obesity have emerged that offer less risk, but questions remain regarding efficacy, durability, and safety. We compared the efficacy of endoscopic bariatric procedures as compared to other existing treatments. METHODS: A literature search of Embase, Cochrane Central, and Pubmed was conducted from January 1, 2014 to December 7, 2021, including endoscopic bariatric therapies that were FDA or CE approved at the time of search to non-endoscopic treatments. Thirty-seven studies involving 15,639 patients were included. Primary outcomes included % total body weight loss (%TBWL), % excess body weight loss (%EBWL), and adverse events. Secondary outcomes included quality of life data and differences in hemoglobin A1C levels. Strength of clinical trial and observational data were graded according to the Cochrane methods. RESULTS: Intragastric balloons achieved greater %TBWL with a range of 7.6-14.1% compared to 3.3-6.7% with lifestyle modification at 6 months, and 7.5-14.0% compared to 3.1-7.9%, respectively, at 12 months. When endoscopic sleeve gastroplasty (ESG) was compared to laparoscopic sleeve gastrectomy (LSG), ESG had less %TBWL at 4.7-14.4% compared to 18.8-26.5% after LSG at 6 months, and 4.5-18.6% as compared to 28.4-29.3%, respectively, at 12 months. For the AspireAssist, there was greater %TBWL with aspiration therapy compared to lifestyle modification at 12 months, 12.1-18.3% TBWL versus 3.5-5.9% TBWL, respectively. All endoscopic interventions had higher adverse events rates compared to lifestyle modification. CONCLUSION: This review is the first to evaluate various endoscopic bariatric therapies using only RCTs and observational studies for evaluation of weight loss compared with conservative management, lifestyle modification, and bariatric surgery. Endoscopic therapies result in greater weight loss compared to lifestyle modification, but not as much as bariatric surgery. Endoscopic therapies may be beneficial as an alternative to bariatric surgery.

BACKGROUND: The COVID-19 pandemic involved a rapid change to the working conditions of all healthcare workers (HCW), including those in primary care. Organizational responses to the pandemic, including a shift to virtual care, changes in staffing, and reassignments to testing-related work, may have shifted more burden to these HCWs, increasing their burnout and turnover intent, despite their engagement to their organization. Our objectives were (1) to examine changes in burnout and intent to leave rates in VA primary care from 2017-2020 (before and during the pandemic), and (2) to analyze how individual protective factors and organizational context affected burnout and turnover intent among VA primary care HCWs during the early months of the pandemic. METHODS: We analyzed individual- and healthcare system-level data from 19,894 primary care HCWs in 139 healthcare systems in 2020. We modeled potential relationships between individual-level burnout and turnover intent as outcomes, and individual-level employee engagement, perceptions of workload, leadership, and workgroups. At healthcare system-level, we assessed prior-year levels of burnout and turnover intent, COVID-19 burden (number of tests and deaths), and the extent of virtual care use as potential determinants. We conducted multivariable analyses using logistic regression with standard errors clustered by healthcare system controlled for individual-level demographics and healthcare system complexity. RESULTS: In 2020, 37% of primary care HCWs reported burnout, and 31% reported turnover intent. Highly engaged employees were less burned out (OR = 0.57; 95% CI 0.52-0.63) and had lower turnover intent (OR = 0.62; 95% CI 0.57-0.68). Pre-pandemic healthcare system-level burnout was a major predictor of individual-level pandemic burnout (p = 0.014). Perceptions of reasonable workload, trustworthy leadership, and strong workgroups were also related to lower burnout and turnover intent (p < 0.05 for all). COVID-19 burden, virtual care use, and prior year turnover were not associated with either outcome. CONCLUSIONS: Employee engagement was associated with a lower likelihood of primary care HCW burnout and turnover intent during the pandemic, suggesting it may have a protective effect during stressful times. COVID-19 burden and virtual care use were not related to either outcome. Future research should focus on understanding the relationship between engagement and burnout and improving well-being in primary care.

BACKGROUND: Civility, or politeness, is an important part of the healthcare workplace, and its absence can lead to healthcare provider and staff burnout. Lack of civility is well-documented among mostly female nurses, but is not well-described among the gender-mixed primary care provider (PCP) workforce. Understanding civility and its relationship to burnout among male and female PCPs could help lead to tailored interventions to improve civility and reduce burnout in primary care. OBJECTIVE: To analyze gender differences in civility, burnout, and the relationship between civility and burnout among male and female PCPs. DESIGN: Multi-level logistic regression analysis of a cross-sectional national survey. PARTICIPANTS: A total of 3216 PCP respondents (1946 women and 1270 men) in 135 medical centers from a 2019 national Veterans Health Administration (VA) survey. MAIN MEASURES: Outcomes: burnout; predictors: workplace civility and gender; controls: race, ethnicity, VA tenure, and supervisory status. KEY RESULTS: Workplace civility was rated higher (p<0.001) among male (mean = 4.07, standard deviation [SD] = 0.36, range 1-5) compared to female (mean = 3.88, SD = 0.33) PCPs. Almost half of the sample reported burnout (47.6%), but this difference was not significant (p = 0.73) between the genders. Higher workplace civility was significantly related to lower burnout among female PCPs (odds ratio [OR] = 0.46, 95% confidence interval [CI] = 0.31 to 0.69), but not among male PCPs (OR = 0.71, 95% CI = 0.42 to 1.22). Interactions between civility and other demographic variables (race, ethnicity, VA tenure, or supervisory status) were not significantly related to burnout. CONCLUSION: Female PCPs report lower workplace civility than male PCPs. An inverse relationship between civility and burnout is present for women but not men. More research is needed on this phenomenon. Interventions tailored to gender- and primary care-specific needs should be employed to increase civility and reduce burnout among PCPs.

INTRODUCTION: Implementation of robot-assisted procedures is growing. Utilization within the country's largest healthcare network, the Veterans Health Administration, is unclear. METHODS: A retrospective cohort study using data from the Department of Veterans Affairs Corporate Data Warehouse from January 2015 through December 2019. Trends in robot utilization for cholecystectomy, ventral hernia repair, and inguinal hernia repair were characterized nationally and regionally by Veterans Integrated Services Network. Patients, who underwent laparoscopic repairs for these procedures and open hernia repairs, were included to determine proportion performed robotically. RESULTS: We identified 119,191 patients, of which 5689 (4.77%) received a robotic operation. The proportion of operations performed robotically increased from 1.49% to 10.55% (7.08-fold change; slope, 2.14% per year; 95% confidence interval [0.79%, 3.49%]). Ventral hernia repair had the largest growth in robotic procedures (1.51% to 13.94%; 9.23-fold change; slope, 2.86% per year; 95% confidence interval [1.04%, 4.68%]). Regions with the largest increase in robotic utilization were primarily along the Northeast, Midwest, and West Coast. CONCLUSIONS: Robot utilization in general surgery is increasing at different rates across the United States in the Veterans Health Administration. Future studies should investigate the regional disparities and drivers of this approach.

INTRODUCTION: The use of the robot in general surgery has exploded in the last decade. The Veterans Health Administration presents a unique opportunity to study differences between surgical approaches due to the ability to control for health system and insurance variability. This study compares clinical outcomes between robot-assisted and laparoscopic or open techniques for three general surgery procedures. METHODS: A retrospective observational study using the Veterans Affair Surgical Quality Improvement Program database. Operative time, length of stay, and complications were compared for cholecystectomy (robot-assisted versus laparoscopic), ventral, and inguinal hernia repair (robot-assisted versus laparoscopic or open) from 2015 to 2019. RESULTS: More than 80,000 cases were analyzed (21,652 cholecystectomy, 9214 ventral hernia repairs, and 51,324 inguinal hernia repairs). Median operative time was longer for all robot-assisted approaches as compared to laparoscopic or open techniques with the largest difference seen between open and robot-assisted primary ventral hernia repair (unadjusted difference of 93 min, P < 0.001). Median length of stay was between 1 and 4 d and significantly for robot-assisted ventral hernia repairs (versus open, P < 0.01; versus lap for recurrent hernia, P < 0.05). Specific postoperative outcomes of interest were overall low with few differences between techniques. CONCLUSIONS: While the robotic platform was associated with longer operative time, these findings must be interpreted in the context of a learning curve and indications for use (i.e., use of the robot for technically challenging cases). Our findings suggest that at the Veterans Health Administration, the robot is as safe a platform for common general surgery procedures as traditional approaches. Future studies should focus on patient-centered outcomes including pain and cosmesis.

INTRODUCTION: Transportation is an important social determinant of health. We conducted a systematic review of the associations on health and health care utilization of interventions aimed at reducing barriers to non-emergency transportation and non-medical transportation. METHODS: We searched three databases and the gray literature through mid-January 2022. Included studies needed to assess an intervention targeted at non-emergency or non-medical transportation barriers, report missed (or kept) visits, health care utilization, costs, or health outcomes. Data extraction was performed in duplicate and included information about study design, results, and risk of bias. Primary outcomes were frequency of missed appointments, health care utilization, costs, and health outcomes. Synthesis was both narrative and meta-analytic using a random effects model. RESULTS: Twelve studies met inclusion criteria, three randomized trials, one controlled trial, and eight observational studies. All included studies had some element of risk of bias. Populations studied usually had chronic or serious health conditions or were poor. Interventions included van rides, bus or taxi vouchers, ride-sharing services, and others. Meta-analysis of seven studies (three trials, four observational studies) yielded a pooled estimate of missed appointments = 0.63 (95% confidence interval [CI] 0.48, 0.83) favoring interventions. Evidence on cost, utilization, and health outcomes were too sparse to support conclusions. Evidence on the effect of non-medical transportation is limited to a single study. CONCLUSIONS AND RELEVANCE: Interventions aimed at non-emergency transportation barriers to access health care are associated with fewer missed appointments; the association with costs, utilization or health outcomes is insufficiently studied to reach conclusions. This review was registered in PROSPERO as ID CRD42020201875.

BACKGROUND: The scope of care coordination in VA primary care increased with the launch of the Veterans Choice Act, which aimed to increase access through greater use of non-VA Community Care. These changes may have overburdened already busy providers with additional administrative tasks, contributing to provider burnout. Our objective was to understand the role of challenges with care coordination in burnout. We analyzed relationships between care coordination challenges with Community Care reported by VA primary care providers (PCPs) and VA PCP burnout. METHODS: Our cross-sectional survey contained five questions about challenges with care coordination. We assessed whether care coordination challenges were associated with two measures of provider burnout, adjusted for provider and facility characteristics. Models were also adjusted for survey nonresponse and clustered by facility. Trainee and executive respondents were excluded. 1,543 PCPs in 129 VA facilities nationwide responded to our survey (13 % response rate). RESULTS: 51 % of our sample reported some level of burnout overall, and 46 % reported feeling burned out at least once a week. PCPs were more likely to be burned out overall if they reported more than average challenges with care coordination (odds ratio [OR] 2.04, 95 % confidence interval [CI] 1.58 to 2.63). These challenges include managing patients with outside prescriptions or obtaining outside tests or records. CONCLUSIONS: VA primary care providers who reported greater than average care coordination challenges were more likely to be burned out. Interventions to improve care coordination could help improve VA provider experience.

Background: Bedside "sitters" are often used for patients at high risk for falls, but they are expensive and their effectiveness is unclear. Purpose: To review evidence about the effect of sitters and alternatives to sitters on patient falls in acute care hospitals. Data Sources: PubMed searches to 8 October 2019, other databases from inception to December 2018, citation searches on key articles, and a Google search (22 October 2019). Study Selection: English-language studies of any design that assessed the effect of adding sitters to usual care or compared alternatives to sitters (for example, video monitors or "close observation units") for adult patients on general wards of acute care hospitals and reported falls as a primary outcome. Data Extraction: Dual-reviewer extraction of study data and risk of bias; single reviewer with group discussion for GRADE (Grading of Recommendations Assessment, Development and Evaluation) certainty of evidence. Data Synthesis: Of 20 studies meeting inclusion criteria, 2 added sitters to usual care and 18 compared alternatives to sitters. There were no randomized trials, 11 time-series studies, 1 retrospective quasi-experimental study, and 8 pre-post studies. All studies had at least 1 methodological limitation. Two studies provided very-low-certainty evidence that adding sitters reduced falls. Eight studies provided moderate-certainty evidence that interventions that included video monitoring reduced sitter use and either did not affect or reduced the number of falls. Very-low-certainty evidence suggested that interventions that included nurse assessment tools (3 studies) or a close observation unit (2 studies) were effective alternatives to sitters. Limitation: No studies had low risk of bias, publication bias is likely, and studies may have been missed. Conclusion: Despite a compelling rationale, evidence is scant that adding sitters to usual care reduces falls. Primary Funding Source: Veterans Affairs Quality Enhancement Research Initiative.

Background: Primary care for a panel of patients is a central component of population health, but the optimal panel size is unclear. Purpose: To review evidence about the association of primary care panel size with health care outcomes and provider burnout. Data Sources: English-language searches of multiple databases from inception to October 2019 and Google searches performed in September 2019. Study Selection: English-language studies of any design, including simulation models, that assessed the association between primary care panel size and safety, efficacy, patient-centeredness, timeliness, efficiency, equity, or provider burnout. Data Extraction: Independent, dual-reviewer extraction; group consensus rating of certainty of evidence. Data Synthesis: Sixteen hypothesis-testing studies and 12 simulation modeling studies met inclusion criteria. All but 1 hypothesis-testing study were cross-sectional assessments of association. Three studies each provided low-certainty evidence that increasing panel size was associated with no or modestly adverse effects on patient-centered and effective care. Eight studies provided low-certainty evidence that increasing panel size was associated with variable effects on timely care. No studies assessed the effect of panel size on safety, efficiency, or equity. One study provided very-low-certainty evidence of an association between increased panel size and provider burnout. The 12 simulation studies evaluated 5 models; all used access as the only outcome of care. Five and 2 studies, respectively, provided moderate-certainty evidence that adjusting panel size for case mix and adding clinical conditions to the case mix resulted in better access. Limitation: No studies had concurrent comparison groups, and published and unpublished studies may have been missed. Conclusion: Evidence is insufficient to make evidence-based recommendations about the optimal primary care panel size for achieving beneficial health outcomes.

INTRODUCTION: Most older Americans use drug therapies for chronic conditions. Several are associated with risk of Alzheimer's disease and related dementias (ADRD). METHODS: A scoping review was used to identify drug classes associated with increasing or decreasing ADRD risk. We analyzed size, type, and findings of the evidence. RESULTS: We identified 29 drug classes across 11 therapeutic areas, and 404 human studies. Most common were studies on drugs for hypertension (93) or hyperlipidemia (81). Fewer than five studies were identified for several anti-diabetic and anti-inflammatory drugs. Evidence was observational only for beta blockers, proton pump inhibitors, benzodiazepines, and disease-modifying anti-rheumatic drugs. For 13 drug classes, 50% or more of the studies reported consistent direction of effect on risk of ADRD. DISCUSSION: Future research targeting drug classes with limited/non-robust evidence, examining sex, racial heterogeneity, and separating classes by molecule, will facilitate understanding of associated risk, and inform clinical and policy efforts to alleviate the growing impact of ADRD.

BACKGROUND: Low back pain is a leading cause of disability in veterans. Chiropractic care is a well-integrated, nonpharmacological therapy in Veterans Affairs health care facilities, where doctors of chiropractic provide therapeutic interventions focused on the management of low back pain and other musculoskeletal conditions. However, important knowledge gaps remain regarding the effectiveness of chiropractic care in terms of the number and frequency of treatment visits needed for optimal outcomes in veterans with low back pain. DESIGN: This pragmatic, parallel-group randomized trial at four Veterans Affairs sites will include 766 veterans with chronic low back pain who are randomly allocated to a course of low-dose (one to five visits) or higher-dose (eight to 12 visits) chiropractic care for 10 weeks (Phase 1). After Phase 1, participants within each treatment arm will again be randomly allocated to receive either monthly chiropractic chronic pain management for 10 months or no scheduled chiropractic visits (Phase 2). Assessments will be collected electronically. The Roland Morris Disability Questionnaire will be the primary outcome for Phase 1 at week 10 and Phase 2 at week 52. SUMMARY: This trial will provide evidence to guide the chiropractic dose in an initial course of care and an extended-care approach for veterans with chronic low back pain. Accurate information on the effectiveness of different dosing regimens of chiropractic care can greatly assist health care facilities, including Veterans Affairs, in modeling the number of doctors of chiropractic that will best meet the needs of patients with chronic low back pain.

BACKGROUND: The clinical effectiveness of surgical versus endovascular therapy for chronic limb-threatening ischemia (CLTI) continues to be debated, and the resources required for each therapy are unclear. METHODS: Systematic review of randomized controlled trials (RCTs) and observational studies comparing surgery with endovascular therapy for CLTI, which reported clinical effectiveness and resource utilization. Short-term and long-term clinical outcomes were examined. RESULTS: The search yielded 4,231 titles, of which 17 publications met our inclusion criteria. Five publications were all from 1 RCT, and 12 publications were observational studies. In the RCT, the surgical approach had greater resource use in the first year (total hospital days across all admissions for surgery versus angioplasty: 46.14 ± 53.87 vs. 36.35 ± 51.39; P < 0.001; also true for days in high-dependency and intensive therapy units), but differences were not statistically significant in subsequent years. All-cause mortality presented a nonsignificant difference favoring angioplasty in the first 2 years (adjusted hazard ratio [aHR], 1.27; 95% confidence interval [95% CI], 0.75-2.15), but after 2 years, it favored surgical treatment (aHR, 0.34; 95% CI, 0.17-0.71). The observational studies reported short-term effectiveness and resource utilization favoring endovascular therapy, but most differences were not statistically significant. Long-term outcomes were more mixed; in particular, mortality outcomes generally favored surgery, although concluding that cause and effect is not possible as endovascularly treated patients tended to be older and may have had a shorter life expectancy regardless of therapy. CONCLUSIONS: The clinical effectiveness and resource utilization of surgery compared with endovascular therapy for CLTI is not known with certainty and will not be known until ongoing trials report results. It is likely that findings will vary by the time horizon, where initial outcomes and utilization tend to favor endovascular interventions, but long-term outcomes favor surgical revascularization.

BACKGROUND: Spinal mobilization and manipulation are 2 therapies found to be generally safe and effective for chronic low back pain (CLBP). However, the question remains whether they are appropriate for all CLBP patients. RESEARCH DESIGN: An expert panel used a well-validated approach, including an evidence synthesis and clinical acumen, to develop and then rate the appropriateness of the use of spinal mobilization and manipulation across an exhaustive list of clinical scenarios which could present for CLBP. Decision tree analysis (DTA) was used to identify the key patient characteristics that affected the ratings. RESULTS: Nine hundred clinical scenarios were defined and then rated by a 9-member expert panel as to the appropriateness of spinal mobilization and manipulation. Across clinical scenarios more were rated appropriate than inappropriate. However, the number patients presenting with each scenario is not yet known. Nevertheless, DTA indicates that all clinical scenarios that included major neurological findings, and some others involving imaging findings of central herniated nucleus pulposus, spinal stenosis, or free fragments, were rated as inappropriate for both spinal mobilization and manipulation. DTA also identified the absence of these imaging findings and no previous laminectomy as the most important patient characteristics in predicting ratings of appropriate. CONCLUSIONS: A well-validated expert panel-based approach was used to develop and then rate the appropriateness of the use of spinal mobilization and manipulation across the clinical scenarios which could present for CLBP. Information on the clinical scenarios for which these therapies are inappropriate should be added to clinical guidelines for CLBP.

PURPOSE: Multifocal intraocular lenses (IOLs) offer the possibility of spectacle-free vision following cataract surgery compared to standard IOLs. Existing systematic reviews have generally concluded that multifocal IOLs result in better uncorrected near vision and greater spectacle independence, but more unwanted visual phenomena such as glare and halos, compared to monofocal IOLs. However, the certainty of evidence has been low for most outcomes, and pooled analyses have grouped together technologically obsolete lenses with newer lenses, potentially obscuring differences in performance across different lens types. METHODS: We performed a systematic review searching for RCTs of a multifocal IOL to a standard IOL or monovision that reported spectacle independence, visual acuity, or quality of life. Databases were searched from 1/1/2006-4/30/2017. Existing reviews were used to identify older studies. Title/abstract screening and data extraction were done in duplicate. Where possible, random effects meta-analysis was performed to synthesize results. In addition to comparing multifocal IOLs as a group to monofocal IOLs, we also compared newer diffractive lenses to obsolete or refractive lenses. RESULTS: Twenty-five eligible studies were identified. There was no difference in pooled estimates of corrected or uncorrected distance vision between multifocal and standard IOLs. Compared to monofocal IOLs, multifocal IOLs had statistically significantly better pooled results for the outcome of near vision (10 studies, 1025 patients, mean difference in logMAR of -0.26 (95% CI -0.37, -0.15)); spectacle dependence (12 studies, 1237 patients, relative risk of 0.27 (95% CI 0.20, 0.38)) and borderline significantly better quality of vision (6 studies, 596 patients, standardized mean difference of -0.54, (95% CI -1.12, 0.04)). Compared to monofocal IOLs, multifocal IOLs had statistically significantly worse pooled results for the outcomes of glare (9 studies, 847 patients, risk ratio of 1.36 (95% CI 1.15, 1.61) and halos (7 studies, 754 patients, risk ratio of 3.14 (95% CI 1.63, 6.08). Newer multifocal lenses had statistically significantly better outcomes than older diffractive lenses or refractive lenses, when compared to monofocal IOLs, in near vision, quality of vision, and risk of halos. CONCLUSIONS: Multifocal IOLs compared to standard IOLs or monovision result in better uncorrected near vision and a higher proportion of patients who achieve spectacle independence, but greater risk of unwanted visual phenomena. Newer diffractive lenses may be better than refractive lenses in near vision and quality of vision outcomes, with less risk of halos than older diffractive lenses and refractive lenses.

BACKGROUND: Payers and policy makers across the international healthcare market are increasingly using publicly available summary measures to designate providers as "high-performing", but no consistently-applied approach exists to identifying high performers. This paper uses publicly available data to examine how different classification approaches influence which providers are designated as "high-performers". METHODS: We conducted a quantitative analysis of cross-sectional publicly-available performance data in the U.S. We used 2014 Minnesota Community Measurement data from 58 medical groups to classify performance across 4 domains: quality (two process measures of cancer screening and 2 composite measures of chronic disease management), total cost of care, access (a composite CAHPS measure), and patient experience (3 CAHPS measures). We classified medical groups based on performance using either relative thresholds or absolute values of performance on all included measures. RESULTS: Using relative thresholds, none of the 58 medical groups achieved performance in the top 25% or 35% in all 4 performance domains. A relative threshold of 40% was needed before one group was classified as high-performing in all 4 domains. Using absolute threshold values, two medical groups were classified as high-performing across all 4 domains. In both approaches, designating "high performance" using fewer domains led to more groups designated as high-performers, though there was little to moderate concordance across identified "high-performing" groups. CONCLUSIONS: Classification of medical groups as high performing is sensitive to the domains of performance included, the classification approach, and choice of threshold. With increasing focus on achieving high performance in healthcare delivery, the absence of a consistently-applied approach to identify high performers impedes efforts to reliably compare, select and reward high-performing providers.
