Review
Studies of the epidemiology of heart failure in the general population can inform assessments of disease burden, research, public health policy and health system care delivery. We performed a systematic review of prevalence, incidence and survival for all available population-representative studies to inform the Global Burden of Disease 2020. We examined population-based studies published between 1990 and 2020 using structured review methods and database search strings. Studies were sought in which heart failure was defined by clinical diagnosis using structured criteria such as the Framingham or European Society of Cardiology criteria, with studies using alternate case definitions identified for comparison. Study results were extracted with descriptive characteristics including age range, location and case definition. Search strings identified 42 360 studies over a 30-year period, of which 790 were selected for full-text review and 125 met criteria for inclusion. 45 sources reported estimates of prevalence, 41 of incidence and 58 of mortality. Prevalence ranged from 0.2%, in a Hong Kong study of hospitalised heart failure patients in 1997, to 17.7%, in a US study of Medicare beneficiaries aged 65+ from 2002 to 2013. Collapsed estimates of incidence ranged from 0.1%, in the EPidémiologie de l'Insuffisance Cardiaque Avancée en Lorraine (EPICAL) study of acute heart failure in France among those aged 20-80 years in 1994, to 4.3%, in a US study of Medicare beneficiaries 65+ from 1994 to 2003. One-year heart failure case fatality ranged from 4% to 45% with an average of 33% overall and 24% for studies across all adult ages. Diagnostic criteria, case ascertainment strategy and demographic breakdown varied widely between studies. Prevalence, incidence and survival for heart failure varied widely across countries and studies, reflecting a range of study design. Heart failure remains a high prevalence disease among older adults with a high risk of death at 1 year.

BACKGROUND
Varying conceptualizations of treatment-resistant depression (TRD) have made translating research findings or systematic reviews into clinical practice guidelines challenging and inconsistent.
METHODS
We conducted a review for the Centers for Medicare & Medicaid Services and the Agency for Healthcare Research and Quality to clarify how experts and investigators have defined TRD and to review systematically how well this definition comports with TRD definitions in clinical trials through July 5, 2019.
RESULTS
We found that no consensus definition existed for TRD. The most common TRD definition for major depressive disorder required a minimum of two prior treatment failures and confirmation of prior adequate dose and duration. The most common TRD definition for bipolar disorder required one prior treatment failure. No clear consensus emerged on defining adequacy of either dose or duration. Our systematic review found that only 17% of intervention studies enrolled samples meeting the most frequently specified criteria for TRD. Depressive outcomes and clinical global impressions were commonly measured; functional impairment and quality-of-life tools were rarely used.
CONCLUSIONS
Two key steps are critical to advancing TRD research: (a) Developing a consensus definition of TRD that addresses how best to specify the number of prior treatment failures and the adequacy of dose and duration; and (b) identifying a core package of outcome measures that can be applied in a standardized manner. Our recommendations about stronger approaches to designing and conducting TRD research will foster better evidence to translate into clearer guidelines for treating patients with this serious condition.

Review
The impact of introducing automated dispensing cabinets, barcode medication administration, and closed-loop electronic medication management systems on work processes and safety of controlled medications in hospitals: A systematic review.
BACKGROUND
Technology in the form of Automated Dispensing Cabinets (ADCs), Barcode Medication Administration (BCMA), and closed-loop Electronic Medication Management Systems (EMMS) are implemented in hospitals to assist with the supply, use and monitoring of medications. Although there is evidence to suggest that these technologies can reduce errors and improve monitoring of medications in general, little is known about their impact on controlled medications such as opioids.
OBJECTIVES
This review aimed to fill this knowledge gap by synthesising literature to determine the impact of ADCs, BCMA and closed-loop EMMS on clinical work processes, medication safety, and drug diversion associated with controlled medications in the inpatient setting.
METHODS
Eight databases (Medline, Pubmed, Embase, Scopus, Web of Science, PsycINFO, CINAHL, and ScienceDirect) were searched for relevant papers published between January 2000 and May 2019. Qualitative, quantitative, and mixed-methods empirical studies published in English that reported findings on the impact of ADCs, BCMA and/or closed-loop EMMS on controlled medications in the inpatient setting were included.
RESULTS
In total, 16 papers met the inclusion criteria. Eleven studies reported on ADCs, four on BCMA, and only one on closed-loop EMMS. Only four studies focused on controlled medications, with the remainder reporting only incidental findings. Studies reported the elimination of manual end-of-shift counts of controlled medications after ADC implementation but cases of drug diversion were reported despite introducing ADCs. Three quantitative studies reported reductions in medication errors after implementing BCMA, but medications labelled with wrong barcodes and unreadable barcodes led to confusion and administration errors.
CONCLUSIONS
More quality, targeted research is needed to provide evidence on the benefits and also risks of implementing technology to safeguard against inappropriate use of controlled medications in the inpatient setting. Processes need to be in place to supplement technological capabilities, and resources should be made available for post-implementation evaluations and interventions.

Review
Multimorbidity, the coexistence of 2 or more chronic conditions, has become prevalent among older adults as mortality rates have declined and the population has aged. We examined population-based administrative claims data indicating specific health service delivery to nearly 31 million Medicare fee-for-service beneficiaries for 15 prevalent chronic conditions. A total of 67% had multimorbidity, which increased with age, from 50% for persons under age 65 years to 62% for those aged 65-74 years and 81.5% for those aged ≥85 years. A systematic review identified 16 other prevalence studies conducted in community samples that included older adults, with median prevalence of 63% and a mode of 67%. Prevalence differences between studies are probably due to methodological biases; no studies were comparable. Key methodological issues arise from elements of the case definition, including type and number of chronic conditions included, ascertainment methods, and source population. Standardized methods for measuring multimorbidity are needed to enable public health surveillance and prevention. Multimorbidity is associated with elevated risk of death, disability, poor functional status, poor quality of life, and adverse drug events. Additional research is needed to develop an understanding of causal pathways and to further develop and test potential clinical and population interventions targeting multimorbidity.

BACKGROUND
Catheter-associated urinary tract infections (CAUTIs) are one of the most common hospital-acquired conditions and no longer reimbursable from Medicare as of 2008. Nurse-driven protocols (NDPs), which provide a medically approved rubric for professional nurses to make autonomous care decisions, can facilitate appropriate catheter use and timely removal, as advised in the Centers for Disease Control and Prevention's 2009 CAUTI prevention guidelines. However, little attempt has been made to systematically evaluate their effect on clinical outcomes.
METHODS
A systematic review of studies published in the United States since 2006 was performed, following guidelines from the Institute of Medicine. Sources included CINAHL, Medline, professional agencies, hand-searching, and expert consultation. Clinical predictors and prevalence of CAUTI were examined and synthesized qualitatively; heterogeneity of outcomes made a statistical meta-analysis inappropriate.
RESULTS
Twenty-nine studies were found eligible for inclusion. All used a case-control (pre-post) approach, and all reported reductions in clinical predictors of CAUTI, particularly indwelling-urinary catheter utilization and CAUTI rates. However, the number of CAUTIs remained unchanged in 1 study. A formal quality assessment revealed a high risk of bias; included studies met an average of 4.9 out of 11 quality indicators. Specifically, many did not use standardized measures.
CONCLUSIONS
NDPs appear to have a positive impact on the clinical predictors and prevalence of CAUTI. However, this review identified need for improving the study design of quality improvement projects conducted within the patient care setting.

Medicare Advantage enrollment has almost doubled since 2010 and now accounts for more than a third of all Medicare beneficiaries. We performed a systematic review to compare Medicare Advantage and traditional Medicare on key metrics. Evidence from forty-eight studies showed that in most or all comparisons, Medicare Advantage was associated with more preventive care visits, fewer hospital admissions and emergency department visits, shorter hospital and skilled nursing facility lengths-of-stay, and lower health care spending. Medicare Advantage outperformed traditional Medicare in most studies comparing quality-of-care metrics. However, the evidence on patient experience, readmission rates, mortality, and racial/ethnic disparities did not show a trend of better performance in Medicare Advantage. Evidence to date might not fully account for selection bias, unobserved differences in social determinants of health, or risk adjustment challenges, in part because of differences in data quality that limit the comparability of outcomes between Medicare Advantage and traditional Medicare. With Medicare Advantage plans expected to grow in popularity, policy makers should support policies to improve data completeness and comparability, and health plans should focus on improving patient experience.

IMPORTANCE
The tort liability system is intended to serve 3 functions: compensate patients who sustain injury from negligence, provide corrective justice, and deter negligence. Deterrence, in theory, occurs because clinicians know that they may experience adverse consequences if they negligently injure patients.
OBJECTIVE
To review empirical findings regarding the association between malpractice liability risk (ie, the extent to which clinicians face the threat of being sued and having to pay damages) and health care quality and safety.
DATA SOURCES AND STUDY SELECTION
Systematic search of multiple databases for studies published between January 1, 1990, and November 25, 2019, examining the relationship between malpractice liability risk measures and health outcomes or structural and process indicators of health care quality.
DATA EXTRACTION AND SYNTHESIS
Information on the exposure and outcome measures, results, and acknowledged limitations was extracted by 2 reviewers. Meta-analytic pooling was not possible due to variations in study designs; therefore, studies were summarized descriptively and assessed qualitatively.
MAIN OUTCOMES AND MEASURES
Associations between malpractice risk measures and health care quality and safety outcomes. Exposure measures included physicians' malpractice insurance premiums, state tort reforms, frequency of paid claims, average claim payment, physicians' claims history, total malpractice payments, jury awards, the presence of an immunity from malpractice liability, the Centers for Medicare & Medicaid Services' Medicare malpractice geographic practice cost index, and composite measures combining these measures. Outcome measures included patient mortality; hospital readmissions, avoidable admissions, and prolonged length of stay; receipt of cancer screening; Agency for Healthcare Research and Quality patient safety indicators and other measures of adverse events; measures of hospital and nursing home quality; and patient satisfaction.
RESULTS
Thirty-seven studies were included; 28 examined hospital care only and 16 focused on obstetrical care. Among obstetrical care studies, 9 found no significant association between liability risk and outcomes (such as Apgar score and birth injuries) and 7 found limited evidence for an association. Among 20 studies of patient mortality in nonobstetrical care settings, 15 found no evidence of an association with liability risk and 5 found limited evidence. Among 7 studies that examined hospital readmissions and avoidable initial hospitalizations, none found evidence of an association between liability risk and outcomes. Among 12 studies of other measures (eg, patient safety indicators, process-of-care quality measures, patient satisfaction), 7 found no association between liability risk and these outcomes and 5 identified significant associations in some analyses.
CONCLUSIONS AND RELEVANCE
In this systematic review, most studies found no association between measures of malpractice liability risk and health care quality and outcomes. Although gaps in the evidence remain, the available findings suggested that greater tort liability, at least in its current form, was not associated with improved quality of care.

OBJECTIVE
Polypharmacy is widespread among older people, but the adverse outcomes associated with it are unclear. We aim to synthesize current evidence on the adverse health, social, medicines management, and health care utilization outcomes of polypharmacy in older people.
DESIGN
A systematic review, of systematic reviews and meta-analyses of observational studies, was conducted. Eleven bibliographic databases were searched from 1990 to February 2018. Quality was assessed using AMSTAR (A Measurement Tool to Assess Systematic Reviews).
SETTING AND PARTICIPANTS
Older people in any health care setting, residential setting, or country.
RESULTS
Twenty-six reviews reporting on 230 unique studies were included. Almost all reviews operationalized polypharmacy as medication count, and few examined medication classes or disease states within this. Evidence for an association between polypharmacy and many adverse outcomes, including adverse drug events and disability, was conflicting. The most consistent evidence was found for hospitalization and inappropriate prescribing. No research had explored polypharmacy in the very old (aged ≥85 years), or examined the potential social consequences associated with medication use, such as loneliness and isolation.
CONCLUSIONS AND IMPLICATIONS
The literature examining the adverse outcomes of polypharmacy in older people is complex, extensive, and conflicting. Until polypharmacy is operationalized in a more clinically relevant manner, the adverse outcomes associated with it will not be fully understood. Future studies should work toward this approach in the face of rising multimorbidity and population aging.

Sports Health 2023To determine optimal treatment strategies for shoulder impingement syndrome (SIS). (Meta-Analysis)
Meta-Analysis Review
CONTEXT
To determine optimal treatment strategies for shoulder impingement syndrome (SIS).
OBJECTIVE
To compare subacromial nonsteroidal anti-inflammatory injections (SNIs) and subacromial corticosteroid injections (SCIs) on pain relief and functional improvement in individuals with SIS. Second, to perform a cost analysis of the 2 injections.
DATA SOURCES
MEDLINE, SPORTDiscus, CINAHL, Embase, Web of Science, and SCOPUS databases were searched for randomized controlled trials using several keywords.
STUDY SELECTION
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized, and 10 studies comparing changes in pain or function in humans with SIS receiving SNIs or SCIs were included. Quality and risk of bias were assessed using the Consolidated Standards of Reporting Trials (CONSORT) 2010 scale and the Cochrane Collaboration tool.
STUDY DESIGN
Systematic review and meta-analysis.
LEVEL OF EVIDENCE
Level 1.
DATA EXTRACTION
Baseline and follow-up scores of the visual analog, Constant-Murley, and University of California Los Angeles shoulder scales were extracted to calculate effect sizes (ESs), represented as Cohen . Metaregression and publication bias analyses were performed. Procedural and medication costs were extracted from Medicare guidelines.
RESULTS
A total of 7 high and 3 good quality studies were included, with a mean score of 21.1. Only 1 study had a high risk of bias. The meta-analyses produced pooled ESs of 0.05 ( = 0.83), 0.12 ( = 0.71), and 0.07 ( = 0.79) for each scale, respectively, with CIs crossing 0. Procedural costs were equal between groups, whereas ketorolac was the least costly medication ($0.47). There was no significant difference in side effects between the 2 injections.
CONCLUSION
SNIs are as effective as SCIs for short-term pain relief and improving function in patients with subacromial impingement syndrome. In addition, they are less expensive and cause no major difference in complications, providing a viable, cost-effective alternative for injection therapy in patients with SIS.

Review
OBJECTIVE
To update a past systematic review on whether Medicare Part D changed drug utilization and out-of-pocket (OOP) costs overall and within subpopulations, and to identify evidence gaps.
DATA SOURCES/STUDY SETTING
Published and gray literature from 2010 to 2015 meeting prespecified screening criteria, including having a comparison group, and utilization or OOP cost outcomes.
STUDY DESIGN
We conducted a systematic literature review with a quality assessment.
DATA COLLECTION/EXTRACTION METHODS
For each study, we extracted information on study design, data sources, analytic methods, outcomes, and limitations. Because outcome measures vary across studies, we did a qualitative synthesis rather than meta-analysis.
PRINCIPAL FINDINGS
Sixty-five studies met screening criteria. Overall, Medicare Part D enrollees have increased drug utilization and decreased OOP costs, but coverage gaps limit the program's impact. Beneficiaries whose insurance becomes more generous after enrollment had disproportionately increased drug utilization and decreased OOP costs. Outcomes among dual-eligibles were mixed.
CONCLUSIONS
There is strong evidence on how Medicare Part D and the donut hole coverage gap affect utilization and OOP costs, but weak evidence on how effects vary among dual-eligibles or across diseases. Findings suggest that the Affordable Care Act's provisions to expand coverage and reduce the donut hole should improve patient outcomes.
