The effects of quality of care on costs: a conceptual framework

Managing and measuring performance of health prevention services: a simulation-based approach

PURPOSE

This study focuses on the application of performance management (PM) in health prevention services. Unlike other healthcare services that focus on individual health results, prevention activities aim at community-wide benefits, often related to the avoidance of negative health outcomes. This, coupled with delayed effects of prevention activities, external influences on results and multiple stakeholders, poses challenges for the management, measurement and accountability of the results achieved by healthcare organisations and systems. To address these challenges, the research proposes the adoption of simulation techniques, specifically system dynamics (SD), to enhance PM in the prevention sector.

DESIGN/METHODOLOGY/APPROACH

SD is a methodological approach developed for modelling and simulating complex systems and experimenting with the models to design strategies and policies. It provides a systemic perspective and a set of conceptual tools that enable one to frame the structure and behaviour of complex, nonlinear, multi-loop feedback systems through an illustrative case focused on the management of primary and secondary prevention of chronic care conditions within a Beveridge healthcare system.

FINDINGS

By employing SD, the study aims to provide decision-makers with the capability to understand the link between immediate outputs and long-term outcomes, facilitating the evaluation of alternative policy options and scenarios that are otherwise untestable due to the long latency of diseases, delayed impact of preventive actions and systemic fragmentation.

ORIGINALITY/VALUE

Through the development of an SD model, this research contributes to the field by offering a novel approach to overcoming the measurement and accountability obstacles in prevention as part of healthcare PM.

The TransFORmation of IndiGEnous PrimAry HEAlthcare Delivery (FORGE AHEAD): economic analysis

BACKGROUND

Indigenous populations have increased risk of developing diabetes and experience poorer treatment outcomes than the general population. The FORGE AHEAD program partnered with First Nations communities across Canada to improve access to resources by developing community-driven primary healthcare models.

METHODS

This was an economic assessment of FORGE AHEAD using a payer perspective. Costs of diabetes management and complications during the 18-month intervention were compared to the costs prior to intervention implementation. Cost-effectiveness of the program assessed incremental differences in cost and number of resources utilization events (pre and post). Primary outcome was all-cause hospitalizations. Secondary outcomes were specialist visits, clinic visits and community resource use. Data were obtained from a diabetes registry and published literature. Costs are expressed in 2023 Can$.

RESULTS

Study population was ~ 60.5 years old; 57.2% female; median duration of diabetes of 8 years; 87.5% residing in non-isolated communities; 75% residing in communities < 5000 members. Total cost of implementation was $1,221,413.60 and cost/person $27.89. There was increase in the number and cost of hospitalizations visits from 8/$68,765.85 (pre period) to 243/$2,735,612.37. Specialist visits, clinic visits and community resource use followed this trend.

CONCLUSION

Considering the low cost of intervention and increased care access, FORGE AHEAD represents a successful community-driven partnership resulting in improved access to resources.

Racial/Ethnic and Geographic Disparities in Comorbid Traumatic Brain Injury-Renal Failure in US Veterans and Associated Veterans Affairs Resource Costs, 2000-2020

Studies have identified disparities by race/ethnicity and geographic status among veterans with traumatic brain injury (TBI) and renal failure (RF). We examined the association of race/ethnicity and geographic status with RF onset in veterans with and without TBI, and the impact of disparities on Veterans Health Administration resource costs.

METHODS

Demographics by TBI and RF status were assessed. We estimated Cox proportional hazards models for progression to RF and generalized estimating equations for inpatient, outpatient, and pharmacy cost annually and time since TBI + RF diagnosis, stratified by age.

RESULTS

Among 596,189 veterans, veterans with TBI progressed faster to RF than those without TBI (HR 1.96). Non-Hispanic Black veterans (HR 1.41) and those in US territories (HR 1.71) progressed faster to RF relative to non-Hispanic Whites and those in urban mainland areas. Non-Hispanic Blacks (-$5,180), Hispanic/Latinos ($-4,984), and veterans in US territories (-$3,740) received fewer annual total VA resources. This was true for all Hispanic/Latinos, while only significant for non-Hispanic Black and US territory veterans < 65 years. For veterans with TBI + RF, higher total resource costs only occurred ≥ 10 years after TBI + RF diagnosis ($32,361), independent of age. Hispanic/Latino veterans ≥ 65 years received $8,248 less than non-Hispanic Whites and veterans living in US territories < 65 years received $37,514 less relative to urban veterans.

CONCLUSION

Concerted efforts to address RF progression in veterans with TBI, especially in non-Hispanic Blacks and those in US territories, are needed. Importantly, culturally appropriate interventions to improve access to care for these groups should be a priority of the Department of Veterans Affairs priority for these groups.

Systematic Review and Meta-Analysis of the Financial Impact of 30-Day Readmissions for Selected Medical Conditions: A Focus on Hospital Quality Performance

BACKGROUND

The Patient Protection and Affordable Care Act (ACA) established the Hospital Quality Initiative in 2010 to enhance patient safety, reduce hospital readmissions, improve quality, and minimize healthcare costs. In response, this study aims to systematically review the literature and conduct a meta-analysis to estimate the average cost of procedure-specific 30-day risk-standardized unplanned readmissions for Acute Myocardial Infarction (AMI), Heart Failure (HF), Pneumonia, Coronary Artery Bypass Graft (CABG), and Total Hip Arthroplasty and/or Total Knee Arthroplasty (THA/TKA).

METHODS

Eligibility Criteria: This study included English language original research papers from the USA, encompassing various study designs. Exclusion criteria comprise studies lacking empirical evidence on hospital financial performance.

INFORMATION SOURCES

A comprehensive search using relevant keywords was conducted across databases from January 1990 to December 2019 (updated in March 2021), covering peer-reviewed articles and gray literature. Risk of Bias: Bias in the included studies was assessed considering study design, adjustment for confounding factors, and potential effect modifiers.

SYNTHESIS OF RESULTS

The review adhered to PRISMA guidelines. Employing Monte Carlo simulations, a meta-analysis was conducted with 100,000 simulated samples. Results indicated mean 30-day readmission costs: USD 16,037.08 (95% CI, USD 15,196.01-16,870.06) overall, USD 6852.97 (95% CI, USD 6684.44-7021.08) for AMI, USD 9817.42 (95% CI, USD 9575.82-10,060.43) for HF, and USD 21,346.50 (95% CI, USD 20,818.14-21,871.85) for THA/TKA.

DISCUSSION

Despite the financial challenges that hospitals face due to the ACA and the Hospital Readmissions Reduction Program, this meta-analysis contributes valuable insights into the consistent cost trends associated with 30-day readmissions.

CONCLUSIONS

This systematic review and meta-analysis provide comprehensive insights into the financial implications of 30-day readmissions for specific medical conditions, enhancing our understanding of the nexus between healthcare quality and financial performance.

The economic impact of cannabis use disorder and dementia diagnosis in veterans diagnosed with traumatic brain injury

Background

Studies have demonstrated that individuals diagnosed with traumatic brain injury (TBI) frequently use medical and recreational cannabis to treat persistent symptoms of TBI, such as chronic pain and sleep disturbances, which can lead to cannabis use disorder (CUD). We aimed to determine the Veterans Health Administration (VHA) healthcare utilization and costs associated with CUD and dementia diagnosis in veterans with TBI.

Methods

This observational study used administrative datasets from the population of post-9/11 veterans from the Long-term Impact of Military-Relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium and the VA Data Warehouse. We compared the differential VHA costs among the following cohorts of veterans: (1) No dementia diagnosis and No CUD group, (2) Dementia diagnosis only (Dementia only), (3) CUD only, and (4) comorbid dementia diagnosis and CUD (Dementia and CUD). Generalized estimating equations and negative binomial regression models were used to estimate total annual costs (inflation-adjusted) and the incidence rate of healthcare utilization, respectively, by dementia diagnosis and CUD status.

Results

Data from 387,770 veterans with TBI (88.4% men; median [interquartile range (IQR)] age at the time of TBI: 30 [14] years; 63.5% white) were followed from 2000 to 2020. Overall, we observed a trend of gradually increasing healthcare costs 5 years after TBI onset. Interestingly, in this cohort of veterans within 5 years of TBI, we observed substantial healthcare costs in the Dementia only group (peak = $46,808) that were not observed in the CUD and dementia group. Relative to those without either condition, the annual total VHA costs were $3,368 higher in the CUD only group, while no significant differences were observed in the Dementia only and Dementia and CUD groups.

Discussion

The findings suggest that those in the Dementia only group might be getting their healthcare needs met more quickly and within 5 years of TBI diagnosis, whereas veterans in the Dementia and CUD group are not receiving early care, resulting in higher long-term healthcare costs. Further investigations should examine what impact the timing of dementia and CUD diagnoses have on specific categories of inpatient and outpatient care in VA and community care facilities.

Using Data-Driven Approaches to Classify and Predict Health Care Spending in Patients With Gout Using Urate-Lowering Therapy

OBJECTIVE

Despite increasing overall health care spending over the past several decades, little is known about long-term patterns of spending among US patients with gout. Current approaches to assessing spending typically focus on composite measures or patients agnostic to disease state; in contrast, examining spending using longitudinal measures may better discriminate patients and target interventions to those in need. We used a data-driven approach to classify and predict spending patterns in patients with gout.

METHODS

Using insurance claims data from 2017-2019, we used group-based trajectory modeling to classify patients ages 40 years or older diagnosed with gout and treated with urate-lowering therapy (ULT) by their total health care spending over 2 years. We assessed the ability to predict membership in each spending group using logistic and generalized boosted regression with split-sample validation. Models were estimated using different sets of predictors and evaluated using C statistics.

RESULTS

In 57,980 patients, the mean ± SD age was 71.0 ± 10.5 years, and 17,194 patients (29.7%) were female. The best-fitting model included the following groups: minimal spending (13.2%), moderate spending (37.4%), and high spending (49.4%). The ability to predict groups was high overall (e.g., boosted C statistics with all predictors: minimal spending [0.89], moderate spending [0.78], and high spending [0.90]). Although average adherence was relatively high in the population, for the high-spending group, the most influential predictors were greater gout medication adherence and diabetes melllitus diagnosis.

CONCLUSION

We identified distinct long-term health care spending patterns in patients with gout using ULT with high accuracy. Several clinical predictors could be key areas for intervention, such as gout medication use or diabetes melllitus.

Economic impact of comorbid TBI-dementia on VA facility and non-VA facility costs, 2000-2020

OBJECTIVE

There is evidence Traumatic Brain Injury (TBI) is associated with increased risk of dementia (D). We compared VA and non-VA facility costs associated with TBI+D and each diagnosis alone, relative to neither diagnosis, annually and over time, 2000-2020.

METHODS

We estimated adjusted panel models of annual VHA costs in VA and non-VA facilities, stratified by age, and by TBI-dementia status. We also estimated cost for the TBI+D cohort by time since TBI and dementia diagnoses. All costs were 2021 inflation adjusted.

RESULTS

Veterans <65 ($30,736) and ≥65 ($15,650) with TBI+D, while veterans <65 ($3,379) and ≥65 ($4,252) with TBI-only had higher annual total VHA costs, relative to neither diagnosis. Veterans with TBI+D < 65 ($42,864) and ≥65 ($72,424) had higher costs in years≥15 after TBI diagnosis, while <65 ($36,431) and ≥65 ($37,589) had higher costs in years ≥10 after dementia diagnosis.

CONCLUSIONS

The main cost driver was inpatient non-VA facility costs. Veterans had continuously increasing inpatient care costs in non-VA facilities over time since their TBI and dementia diagnoses. Given budget constraints on the VA system, quality of care in non-VA facilities warrants comparison with VA facilities to make informed decisions regarding referrals to non-VA facilities.

Economic evaluation of quality improvement interventions to prevent catheter-associated urinary tract infections in the hospital setting: a systematic review

BACKGROUND

Hospitals have implemented diverse quality improvement (QI) interventions to reduce rates of catheter-associated urinary tract infections (CAUTIs). The economic value of these QI interventions is uncertain.

OBJECTIVE

To systematically review economic evaluations of QI interventions designed to prevent CAUTI in acute care hospitals.

METHODS

A search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicine's Grey Literature Report, WorldCat, IDWeek conference abstracts and prior systematic reviews was conducted from January 2000 to October 2020.We included English-language studies of any design that evaluated organisational or structural changes to prevent CAUTI in acute care hospitals, and reported programme and infection-related costs.Dual reviewers assessed study design, effectiveness, costs and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net cost/savings per hospital over 3 years. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter days per study.

RESULTS

Fifteen unique economic evaluations were eligible, encompassing 74 hospitals. Across 12 studies amenable to standardisation, QI interventions were associated with a 43% decline in infections (mean IRR 0.57, 95% CI 0.44 to 0.70) and wide ranges of net costs (mean US$52 000, 95% CI -$288 000 to $392 000), relative to usual care.

CONCLUSIONS

QI interventions were associated with large declines in infection rates and net costs to hospitals that varied greatly but that, on average, were not significantly different from zero over 3 years. Future research should examine specific practices associated with cost-savings and clinical effectiveness, and examine whether or not more comprehensive interventions offer hospitals and patients the best value.

Nurses as Gifted Artists in Caring: An Analysis of Nursing Care Concept

Background

Nursing care happens with the artistic presence of the nurse in the care setting. Despite its importance in nursing, yet many ambiguities surround its definition and characteristics. The aim of this study was to analyze the concept of nursing care.

Materials and Methods

This concept analysis was conducted using Walker and Avant's approach. An extensive literature search was done in the Medline, CINAHL, Embase and SID databases to find articles published in English between 1988 and 2019. The search keywords were "care", "nursing care", "concept", "concept analysis", and similar words. According to Walker and Avant's approach, after selecting the concept and determining the aim of analysis, 3742 references were reviewed and 68 articles and 2 books were selected to determine and extract the defining attributes, antecedents, consequences, and empirical referents of the nursing care concept.

Results

The three main defining attributes of the concept were relationship, compassion, and professional action. The antecedents were nurse-related, client-related and environment-related, and the consequences were for nurses, clients and community.

Conclusions

The defining attributes, antecedents, and consequences determined in the present study help better understand the concept of nursing care. This study highlights the importance of the communicative, caring, and advocacy roles of nurses and their compassionate professional action in the promotion of individual and community health.

Evaluation of the Healthcare Cost Offsets of Mend: A Family Systems Mental Health Integration Approach

Behavioral and physical health integration has been shown to be beneficial for overall health outcomes, as well as financial benefits. The current research clearly shows benefits, but lacks evidence specific to couples and family therapy (CFT) as a medium or profession within mental health integrated sites. This study tests the cost offsets of Mastering Each New Directions (MEND), a family system psychosocial approach to chronic illness (CI). Using retrospective charges from 107 CI adult patients, MEND (with an average of 25 sessions) was estimated to produce a 12-month cost savings of $16,684 or a 34.3% reduction in healthcare costs. This reduction significantly outweighed the cost of the intervention for a total net savings of $9,251 per participant in 12 months. Variations in cost reductions by demographic and treatment dosage are explored, and results suggest that a family systems psychosocial intervention can offer a health system an overall cost savings.

Impact of Poor Oral Health on Community-Dwelling Seniors: A Scoping Review

The aim of this scoping review was to determine health-related impacts of poor oral health among community-dwelling seniors. Using MeSH terms and keywords such as elderly, general health, geriatrics, 3 electronic databases-Medline, CINAHL, and Age Line were searched. Title and abstracts were independently screened by 3 reviewers, followed by full-texts review. A total of 131 articles met our inclusion criteria, the majority of these studies were prospective cohort (77%, n = 103), and conducted in Japan (42 %, n = 55). These studies were categorized into 16 general health outcomes, with mortality (24%, n = 34), and mental health disorders (21%, n = 30) being the most common outcomes linked with poor oral health. 90% (n = 120) of the included studies reported that poor oral health in seniors can subsequently lead to a higher risk of poor general health outcomes among this population. Improving access to oral healthcare services for elderly can help not only reduce the burden of oral diseases in this population group but also address the morbidity and mortality associated with other general health diseases and conditions caused due to poor oral health. Findings from this study can help identify shortcomings in existing oral healthcare programs for elderly and develop future programs and services to improve access and utilization of oral care services by elderly.

Use of Data-Driven Methods to Predict Long-term Patterns of Health Care Spending for Medicare Patients

Importance

Current approaches to predicting health care costs generally rely on a single composite value of spending and focus on short time horizons. By contrast, examining patients' spending patterns using dynamic measures applied over longer periods may better identify patients with different spending and help target interventions to those with the greatest need.

Objective

To classify patients by their long-term, dynamic health care spending patterns using a data-driven approach and assess the ability to predict spending patterns, particularly using characteristics that are potentially modifiable through intervention.

Design, Setting, and Participants

This cohort study used a retrospective cohort design from a random nationwide sample of Medicare fee-for-service administrative claims data to identify beneficiaries aged 65 years or older with continuous eligibility from 2011 to 2013. Statistical analysis was performed from August 2018 to December 2019.

Main Outcomes and Measures

Group-based trajectory modeling was applied to the claims data to classify the Medicare beneficiaries by their total health care spending patterns over a 2-year period. The ability to predict membership in each trajectory spending group was assessed using generalized boosted regression, a data mining approach to model building and prediction, with split-sample validation. Models were estimated using (1) prior-year predictors and (2) prior-year predictors potentially modifiable through intervention measured in the claims data. These models were evaluated using validated C-statistics. The relative influence of individual predictors in the models was evaluated.

Results

Among the 329 476 beneficiaries, the mean (SD) age was 76.0 (7.2) years and 190 346 (57.8%) were female. This final 5-group model included a minimal-user group (group 1, 37 572 individuals [11.4%]), a low-cost group (group 2, 48 575 individuals [14.7%]), a rising-cost group (group 3, 24 736 individuals [7.5%]), a moderate-cost group (group 4, 83 338 individuals [25.3%]), and a high-cost group (group 5, 135 255 individuals [41.2%]). Potentially modifiable characteristics strongly predicted these patterns (C-statistics range: 0.68-0.94). For groups with progressively increasing spending in particular, the most influential factors were number of medications (relative influence: 29.2), number of office visits (relative influence: 30.3), and mean medication adherence (relative influence: 33.6).

Conclusions and Relevance

Using a data-driven approach, distinct spending patterns were identified with high accuracy. The potentially modifiable predictors of membership in the rising-cost group represent important levers for early interventions that may prevent later spending increases. This approach could be adapted by organizations to target quality improvement interventions, particularly because numerous health care organizations are increasingly using these routinely collected data.

A Systematic Review of the Association Between Hospital Cost/price and the Quality of Care

BACKGROUND

Limited empirical evidence exists regarding the effect of price changes on hospital behavior and, ultimately, the quality of care. Additionally, an overview of the results of prior literature is lacking.

OBJECTIVE

This study aims to provide a synthesis of existing research concerning the relationship between hospital cost/price and the quality of care.

METHODS

Searches for literature related to the effect of hospital cost and price on the quality of care, including studies published between 1990 and March 2019, were carried out using four electronic databases. In total, 47 studies were identified, and the data were extracted and summarized in different tables to identify the patterns of the relationships between hospital costs/prices and the quality of care.

RESULTS

The study findings are highly heterogenous. The proportion of studies detecting a significant positive association between price/cost and the quality of care is higher when (a) price/reimbursement is used (instead of cost); (b) process measures are used (instead of outcome measures); (c) the focus is on acute myocardial infarction, congestive heart failure, and stroke patients (instead of patients with other clinical conditions or all patients); and (d) the methodological approach used to address confounding is more sophisticated.

CONCLUSION

Our results suggest that there is no general relationship between cost/price and the quality of care. However, the relationship seems to depend on the condition and specific resource utilization. Policy makers should be prudent with the measures used to reduce hospital costs to avoid endangering the quality of care, especially in resource-sensitive settings.

Not there yet: using data-driven methods to predict who becomes costly among low-cost patients with type 2 diabetes

BACKGROUND

Diabetes is a leading cause of Medicare spending; predicting which individuals are likely to be costly is essential for targeting interventions. Current approaches generally focus on composite measures, short time-horizons, or patients who are already high utilizers, whose costs may be harder to modify. Thus, we used data-driven methods to classify unique clusters in Medicare claims who were initially low utilizers by their diabetes spending patterns in subsequent years and used machine learning to predict these patterns.

METHODS

We identified beneficiaries with type 2 diabetes whose spending was in the bottom 90% of diabetes care spending in a one-year baseline period in Medicare fee-for-service data. We used group-based trajectory modeling to classify unique clusters of patients by diabetes-related spending patterns over a two-year follow-up. Prediction models were estimated with generalized boosted regression, a machine learning method, using sets of all baseline predictors, diabetes predictors, and predictors that are potentially-modifiable through interventions. Each model was evaluated through C-statistics and 5-fold cross-validation.

RESULTS

Among 33,789 beneficiaries (baseline median diabetes spending: $4153), we identified 5 distinct spending patterns that could largely be predicted; of these, 68.1% of patients had consistent spending, 25.3% had spending that rose quickly, and 6.6% of patients had spending that rose progressively. The ability to predict these groups was moderate (validated C-statistics: 0.63 to 0.87). The most influential factors for those with progressively rising spending were age, generosity of coverage, prior spending, and medication adherence.

CONCLUSIONS

Patients with type 2 diabetes who were initially low spenders exhibit distinct subsequent long-term patterns of diabetes spending; membership in these patterns can be largely predicted with data-driven methods. These findings as well as applications of the overall approach could potentially inform the design and timing of diabetes or cost-containment interventions, such as medication adherence or interventions that enhance access to care, among patients with type 2 diabetes.

Cost Modifications during the Early Years of the Use of the National Cardiovascular Data Registry for Quality Improvement

OBJECTIVES

Quality improvement (QI) initiatives based on data from international registries have been reported previously; however, there is a lack of information on the impact on the costs of medical care associated with the use of these tools.

METHODS

Patients admitted due to myocardial infarction (MI), included in the ACTION Registry® and CathPCI Registry®, in a private Brazilian hospital (i.e., the reference hospital) were analyzed. The costs of care of these patients were compared to the costs of MI admissions in nine similar hospitals not included in the same QI program. Regression models were used to analyze the cost change over time between the two groups of hospitals. Readmission rates were compared using logistic regression, adjusting for the same variables as in the cost model.

RESULTS

Overall, the annual medical cost inflation in Brazil was higher than the annual cost trend in the reference hospital during the period of analysis. Moreover, the annual in-hospital costs indicate that the reference hospital has a statistically significant 6% lower cost trend for patients with acute MI, compared to patients with the same diagnostic code in the comparison hospitals group, in an adjusted analysis (p-value=0.041). Using multivariable analysis, the readmission rates were also found to be significantly lower in the reference hospital than in the comparison hospitals, with an odds ratio of 0.68 (p-value=0.042).

CONCLUSION

The use of the NCDR® as a benchmark to guide QI programs outside the United States was associated with the positive impact of bending the cost curve to below that of national medical inflation and the comparison hospitals' costs, with a lower incidence of hospital readmission.

Cost-Effectiveness of Advanced Practice Nurses Compared to Physician-Led Care for Chronic Diseases: A Systematic Review

Globally, advanced practice nurses (APNs) provide high-quality chronic disease care to patients, yet the cost-effectiveness of their services is minimally explored. This review aims to determine the cost-effectiveness of chronic disease care provided by APNs compared to physicians globally.

Evaluation of an Intervention to Reduce Low-Value Preoperative Care for Patients Undergoing Cataract Surgery at a Safety-Net Health System

IMPORTANCE

Preoperative testing for cataract surgery epitomizes low-value care and still occurs frequently, even at one of the nation's largest safety-net health systems.

OBJECTIVE

To evaluate a multipronged intervention to reduce low-value preoperative care for patients undergoing cataract surgery and analyze costs from various fiscal perspectives.

DESIGN, SETTING, AND PARTICIPANTS

This study took place at 2 academic safety-net medical centers, Los Angeles County and University of Southern California (LAC-USC) (intervention, n = 469) and Harbor-UCLA (University of California, Los Angeles) (control, n = 585), from April 13, 2015, through April 12, 2016, with 12 additional months (April 13, 2016, through April 13, 2017) to assess sustainability (intervention, n = 1002; control, n = 511). To compare pre- and postintervention vs control group utilization and cost changes, logistic regression assessing time-by-group interactions was used.

INTERVENTIONS

Using plan-do-study-act cycles, a quality improvement nurse reviewed medical records and engaged the anesthesiology and ophthalmology chiefs with data on overuse; all 3 educated staff and trainees on reducing routine preoperative care.

MAIN OUTCOMES AND MEASURES

Percentage of patients undergoing cataract surgery with preoperative medical visits, chest x-rays, laboratory tests, and electrocardiograms. Costs were estimated from LAC-USC's financially capitated perspective, and costs were simulated from fee-for-service (FFS) health system and societal perspectives.

RESULTS

Of 1054 patients, 546 (51.8%) were female (mean [SD] age, 60.6 [11.1] years). Preoperative visits decreased from 93% to 24% in the intervention group and increased from 89% to 91% in the control group (between-group difference, -71%; 95% CI, -80% to -62%). Chest x-rays decreased from 90% to 24% in the intervention group and increased from 75% to 83% in the control group (between-group difference, -75%; 95% CI, -86% to -65%). Laboratory tests decreased from 92% to 37% in the intervention group and decreased from 98% to 97% in the control group (between-group difference, -56%; 95% CI, -64% to -48%). Electrocardiograms decreased from 95% to 29% in the intervention group and increased from 86% to 94% in the control group (between-group difference, -74%; 95% CI, -83% to -65%). During 12-month follow-up, visits increased in the intervention group to 67%, but chest x-rays (12%), laboratory tests (28%), and electrocardiograms (11%) remained low (P < .001 for all time-group interactions in both periods). At LAC-USC, losses of $42 241 in year 1 were attributable to intervention costs, and 3-year projections estimated $67 241 in savings. In a simulation of a FFS health system at 3 years, $88 151 in losses were estimated, and for societal 3-year perspectives, $217 322 in savings were estimated.

CONCLUSIONS AND RELEVANCE

This intervention was associated with sustained reductions in low-value preoperative testing among patients undergoing cataract surgery and modest cost savings for the health system. The findings suggest that reducing low-value care may be associated with cost savings for financially capitated health systems and society but also with losses for FFS health systems, highlighting a potential barrier to eliminating low-value care.

A multidisciplinary approach to the clinical management of Prader-Willi syndrome

Background

Prader–Willi syndrome (PWS) is a complex neuroendocrine disorder affecting approximately 1/15,000–1/30,000 people. Unmet medical needs of individuals with PWS make it a rare disease that models the importance of multidisciplinary approaches to care with collaboration between academic centers, medical homes, industry, and parent organizations. Multidisciplinary clinics support comprehensive, patient‐centered care for individuals with complex genetic disorders and their families. Value comes from improved communication and focuses on quality family‐centered care.

Methods

Interviews with medical professionals, scientists, managed care experts, parents, and individuals with PWS were conducted from July 1 to December 1, 2016. Review of the literature was used to provide support.

Results

Data are presented based on consensus from these interviews by specialty focusing on unique aspects of care, research, and management. We have also defined the Center of Excellence beyond the multidisciplinary clinic.

Conclusion

Establishment of clinics motivates collaboration to provide evidence‐based new standards of care, increases the knowledge base including through randomized controlled trials, and offers an additional resource for the community. They have a role in global telemedicine, including to rural areas with few resources, and create opportunities for clinical work to inform basic and translational research. As a care team, we are currently charged with understanding the molecular basis of PWS beyond the known genetic cause; developing appropriate clinical outcome measures and biomarkers; bringing new therapies to change the natural history of disease; improving daily patient struggles, access to care, and caregiver burden; and decreasing healthcare load. Based on experience to date with a PWS multidisciplinary clinic, we propose a design for this approach and emphasize the development of “Centers of Excellence.” We highlight the dearth of evidence for management approaches creating huge gaps in care practices as a means to illustrate the importance of the collaborative environment and translational approaches.

Medicare Shared Savings Programs: Higher Cost Accountable Care Organizations are More Likely to Achieve Savings

In the United States, Medicare's flagship Accountable Care Organization (ACO) program, the Medicare Shared Savings Program (MSSP), is under close scrutiny to improve health care quality and decrease costs. First year measures, released in November 2014, reveal a wide range of financial and quality performance across MSSP participants. In this observational study we used 2013 results for 220 participating ACOs to assess key characteristics associated with generating savings. ACOs with higher baseline expenditures were significantly more likely to generate savings than lower cost ACOs. Average quality scores for ACOs that successfully reported on quality were not different between organizations that did and did not generate savings. These findings suggest ACOs that had lower utilization prior to program enrollment are less likely to be rewarded in the current program. This has important policy implications for the MSSP's ability to attract and retain efficient ACOs and incent efforts to reduce waste and improve quality.

Association between provider specialty and healthcare costs and glycemic control for patients with diabetes

AIMS

To analyze the association between provider, healthcare costs, and glycemic control for patients with diabetes mellitus (DM).

MATERIALS AND METHODS

This cross-sectional study identified adults with type 1 or 2 DM (T1D, T2D) in the Optum database. The main independent variable was provider (endocrinologist or primary care). Regression analysis compared total medical and pharmacy costs, adjusting for health status and other patient differences, by provider.

RESULTS

For all patients, HbA1C improvement was greater, and medical costs significantly lower with an endocrinologist rather than a primary care provider. The largest HbA1C improvement (4%) occurred for insulin-dependent patients seen by endocrinologists. Significant medical savings with endocrinologist management occurred within the Medicare Advantage population in every sub-group of patients, with 14% lower costs ($4,767) for patients with T1D, 11% lower costs ($3,160) for patients with macro- and microvascular complications, and 10% lower costs ($2,237) for insulin-dependent patients. Within the commercial insurance population, medical costs were reduced by ≥9% in every sub-group of patients, with a 20% reduction ($8,450) for patients with micro- and macrovascular complications. Overall total costs (medical and pharmacy) were 8% ($1,541) higher for patients receiving endocrinologist rather than primary care, although endocrinologist care resulted in a 9% reduction (-$3,710) in costs for Medicare Advantage patients with T1D. Total medical costs (excluding pharmacy costs) may be a more accurate indicator of costs associated with patients in various stages of DM.

LIMITATIONS

There was insufficient data to develop risk-adjustment payments for pharmacy costs based on disease severity. The cross-sectional design identifies associations and not cause-effect relationships.

CONCLUSION

DM management by an endocrinologist was associated with greater HbA1C improvement and significantly lower medical costs. Total costs were higher with an endocrinologist, but for patients with T1D lower costs were seen, ranging from 2-9% regardless of insurance type.

Economic Evaluation of Quality Improvement Interventions Designed to Improve Glycemic Control in Diabetes: A Systematic Review and Weighted Regression Analysis

OBJECTIVE

Quality improvement (QI) interventions can improve glycemic control, but little is known about their value. We systematically reviewed economic evaluations of QI interventions for glycemic control among adults with type 1 or type 2 diabetes.

RESEARCH DESIGN AND METHODS

We used English-language studies from high-income countries that evaluated organizational changes and reported program and utilization-related costs, chosen from PubMed, EconLit, Centre for Reviews and Dissemination, New York Academy of Medicine's Grey Literature Report, and WorldCat (January 2004 to August 2016). We extracted data regarding intervention, study design, change in HbA1c, time horizon, perspective, incremental net cost (studies lasting ≤3 years), incremental cost-effectiveness ratio (ICER) (studies lasting ≥20 years), and study quality. Weighted least-squares regression analysis was used to estimate mean changes in HbA1c and incremental net cost.

RESULTS

Of 3,646 records, 46 unique studies were eligible. Across 19 randomized controlled trials (RCTs), HbA1c declined by 0.26% (95% CI 0.17-0.35) or 3 mmol/mol (2 to 4) relative to usual care. In 8 RCTs lasting ≤3 years, incremental net costs were $116 (95% CI -$612 to $843) per patient annually. Long-term ICERs were $100,000-$115,000/quality-adjusted life year (QALY) in 3 RCTs, $50,000-$99,999/QALY in 1 RCT, $0-$49,999/QALY in 4 RCTs, and dominant in 1 RCT. Results were more favorable in non-RCTs. Our limitations include the fact that the studies had diverse designs and involved moderate risk of bias.

CONCLUSIONS

Diverse multifaceted QI interventions that lower HbA1c appear to be a fair-to-good value relative to usual care, depending on society's willingness to pay for improvements in health.

Governing the quality and safety of healthcare: A conceptual framework

Recent research has advanced understanding of corporate governance of healthcare quality, highlighting the need for future empirical work to develop beyond a focus on board composition to a more detailed exploration of the internal workings of governance that influence board engagement and activities. This paper proposes a conceptual framework to guide empirical research examining the work of board and senior management in governing healthcare quality. To generate this framework, existing conceptual approaches and key constructs influencing effectiveness are identified in the governance literature. Commonalities between governance and team effectiveness literature are mapped and suggest a number of key constructs in the team effectiveness literature are applicable to, but not yet fully explored, within the governance literature. From these we develop a healthcare governance conceptual framework encompassing both literatures, that outlines input and mediating factors influencing governance. The mapping process highlights gaps in research related to board dynamics and external influences that require further investigation. Organizing the multiple complex factors that influence governance of healthcare quality in a conceptual framework brings a new perspective to structuring theory-led research and informing future policy initiatives.

Economic Evaluation of Quality Improvement Interventions Designed to Prevent Hospital Readmission: A Systematic Review and Meta-analysis

Importance

Quality improvement (QI) interventions can reduce hospital readmission, but little is known about their economic value.

Objective

To systematically review economic evaluations of QI interventions designed to reduce readmissions.

Data Sources

Databases searched included PubMed, Econlit, the Centre for Reviews & Dissemination Economic Evaluations, New York Academy of Medicine's Grey Literature Report, and Worldcat (January 2004 to July 2016).

Study Selection

Dual reviewers selected English-language studies from high-income countries that evaluated organizational or structural changes to reduce hospital readmission, and that reported program and readmission-related costs.

Data Extraction and Synthesis

Dual reviewers extracted intervention characteristics, study design, clinical effectiveness, study quality, economic perspective, and costs. We calculated the risk difference and net costs to the health system in 2015 US dollars. Weighted least-squares regression analyses tested predictors of the risk difference and net costs.

Main Outcomes and Measures

Main outcomes measures included the risk difference in readmission rates and incremental net cost. This systematic review and data analysis is reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines.

Results

Of 5205 articles, 50 unique studies were eligible, including 25 studies in populations limited to heart failure (HF) that included 5768 patients, 21 in general populations that included 10 445 patients, and 4 in unique populations. Fifteen studies lasted up to 30 days while most others lasted 6 to 24 months. Based on regression analyses, readmissions declined by an average of 12.1% among patients with HF (95% CI, 8.3%-15.9%; P < .001; based on 22 studies with complete data) and by 6.3% among general populations (95% CI, 4.0%-8.7%; P < .001; 18 studies). The mean net savings to the health system per patient was $972 among patients with HF (95% CI, -$642 to $2586; P = .23; 24 studies), and the mean net loss was $169 among general populations (95% CI, -$2610 to $2949; P = .90; 21 studies), reflecting nonsignificant differences. Among general populations, interventions that engaged patients and caregivers were associated with greater net savings ($1714 vs -$6568; P = .006).

Conclusions and Relevance

Multicomponent QI interventions can be effective at reducing readmissions relative to the status quo, but net costs vary. Interventions that engage general populations of patients and their caregivers may offer greater value to the health system, but the implications for patients and caregivers are unknown.

Economic Evaluation of Quality Improvement Interventions for Bloodstream Infections Related to Central Catheters: A Systematic Review

IMPORTANCE

Although quality improvement (QI) interventions can reduce central-line-associated bloodstream infections (CLABSI) and catheter-related bloodstream infections (CRBSI), their economic value is uncertain.

OBJECTIVE

To systematically review economic evaluations of QI interventions designed to prevent CLABSI and/or CRBSI in acute care hospitals.

EVIDENCE REVIEW

A search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicine's Grey Literature Report, Worldcat, prior systematic reviews (January 2004 to July 2016), and IDWeek conference abstracts (2013-2016), was conducted from 2013 to 2016. We included English-language studies of any design that evaluated organizational or structural changes to prevent CLABSI or CRBSI, and reported program and infection-related costs. Dual reviewers assessed study design, effectiveness, costs, and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net savings. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter-days per study per year.

FINDINGS

Of 505 articles, 15 unique studies were eligible, together representing data from 113 hospitals. Thirteen studies compared Agency for Healthcare Research and Quality-recommended practices with usual care, including 7 testing insertion checklists. Eleven studies were based on uncontrolled before-after designs, 1 on a randomized controlled trial, 1 on a time-series analysis, and 2 on modeled estimates. Overall, the weighted mean IRR was 0.43 (95% CI, 0.35-0.51) and incremental net savings were $1.85 million (95% CI, $1.30 million to $2.40 million) per hospital over 3 years (2015 US dollars). Each $100 000-increase in program cost was associated with $315 000 greater savings (95% CI, $166 000-$464 000; P < .001). Infections and net costs declined when hospitals already used checklists or had baseline infection rates of 1.7 to 3.7 per 1000 catheter-days. Study quality was not associated with effectiveness or costs.

CONCLUSIONS AND RELEVANCE

Interventions related to central venous catheters were, on average, associated with 57% fewer bloodstream infections and substantial savings to hospitals. Larger initial investments may be associated with greater savings. Although checklists are now widely used and infections have started to decline, additional improvements and savings can occur at hospitals that have not yet attained very low infection rates.

Linking Spending and Quality Indicators to Measure Value and Efficiency in Health Care

Policy makers and stakeholders have reached a consensus that both quality and spending or resource use indicators should be jointly measured and prioritized to meet the objectives of our health system. However, the relative merits of alternative approaches that combine quality and spending indicators are not well understood. We conducted a literature review to identify different approaches that combine indicators of quality and spending measures to profile provider efficiency in the context of specific applications in health care. Our investigation identified seven alternative models that are either in use or have been proposed to evaluate provider efficiency. We then used publicly available data to profile hospitals using these approaches. Profiles of hospital efficiency using alternative models yielded wide variation in performance, underscoring the importance of model selection. By identifying the current efficiency models and evaluating their trade-offs within specific programmatic contexts, our analysis informs stakeholder and policy maker decisions about how to link quality and spending indicators when measuring efficiency in health care.

Pessoas com dor e necessidades de intervenção: revisão sistemática da literatura

Objectivou-se determinar qual o impacto económico e social e as necessidades de intervenção por parte dos serviços de saúde, relativamente às pessoas com dor. Foi efectuada uma pesquisa na EBSCO (CINAHL, MEDLINE, British Nursing Index), utilizando-se o método de PI[C]O e seleccionados 19 artigos do total de 325 encontrados. A dor de tipo neuropática e a com localização músculo-esquelética foram identificadas como as maiores responsáveis pelos gastos em saúde. Como factores positivamente associados à relação custo-eficácia, encontrou-se: associação do regime terapêutico com estratégias não farmacológicas, intervenção de equipas multidisciplinares especializadas no controlo da dor, continuidade de cuidados na comunidade e uma linha telefónica de apoio permanente. Conclui-se que a dor causa significativa deterioração na qualidade de vida, com incalculável impacto no desempenho das actividades de vida diária.
