Health literacy competency requirements for health professionals: a Delphi consensus study in Taiwan.

BACKGROUND: Cumulative evidence supports the importance of health literacy in determining the quality of healthcare delivery and outcomes. To enhance health literacy competencies among professionals and alleviate healthcare barriers owing to patients' inadequate health literacy, evidence-based health literacy competency guidelines are needed for the development of health professionals' training curricula. The aim of this study was to validate and refine a set of health literacy competencies, including knowledge, attitude, and skills of health professionals, and to prioritize the importance of health literacy practices among healthcare professionals. METHODS: We employed a consensus-building approach that utilized a modified three-round Delphi process conducted in 2017. An online Delphi panel was assembled, comprising 20 Taiwanese health literacy experts from diverse fields such as medicine, nursing, public health, language, and communication. A set of health literacy competencies previously identified and validated by an international panel of health literacy experts was cross-culturally translated. RESULTS: After three rounds of ratings and modifications, a consensus agreement was reached on 42 of 62 health literacy competencies, including 12 of 24 knowledge items, 9 of 11 attitude items, and 21 of 27 skill items. Of the 32 health literacy practices, "avoidance using medical jargon," "speaking slowly and clearly with patients," and "using analogies and examples" were deemed most important by the panelists. CONCLUSIONS: The Delphi panel's consensus helped to identify a set of core health literacy competencies that could serve as measurable learning objectives to guide the development of a health literacy curriculum for health professionals. The prioritized health literacy practices can be employed as indicators of health literacy competencies that health professionals should learn and routinely use in clinical settings.

Hospital Finances During the First Two Years of the COVID-19 Pandemic: Evidence From Washington State Hospitals.

The COVID-19 pandemic created a broad array of challenges for hospitals. These challenges included restrictions on admissions and procedures, patient surges, rising costs of labor and supplies, and a disparate impact on already disadvantaged populations. Many of these intersecting challenges put pressure on hospitals' finances. There was concern that financial pressure would be particularly acute for hospitals serving vulnerable populations, including safety-net (SN) hospitals and critical access hospitals (CAHs). Using data from hospitals in Washington State, we examined changes in operating margins for SN hospitals, CAHs, and other acute care hospitals in 2020 and 2021. We found that the operating margins for all three categories of hospitals fell from 2019 to 2020, with SNs and CAHs sustaining the largest declines. During 2021, operating margins improved for all three hospital categories but SN operating margins still remained negative. Both changes in revenue and changes in expenses contributed to observed changes in operating margins. Our study is one of the first to describe how the financial effects of COVID-19 differed for SNs, CAHs, and other acute care hospitals over the first two years of the pandemic. Our results highlight the continuing financial vulnerability of SNs and demonstrate how the factors that contribute to profitability can shift over time.

Validation of the Measurement Approaches to Partnership Success (MAPS) Questionnaire.

Conceptualizing and testing factors that contribute to the success of community-academic partnerships are critical to understanding their contributions to the health and well-being of communities. Most measures to date focus on factors that contribute to the development of new partnerships, and only a few have been adequately tested and validated. Methods. The Measurement Approaches to Partnership Success (MAPS) study followed a community-based participatory research (CBPR) approach and a multiphase process that included the construction and pilot testing of a questionnaire, and a national survey to validate the psychometric properties of the questionnaire in long-standing CBPR partnerships (existing ≥ six years). All members within partnerships were recruited to complete the survey (55 partnerships with 563 partners). We used confirmatory factor analysis (CFA), Cronbach's alpha statistics, and a pairwise correlations approach to assess discriminant and convergent validity, and assessed internal consistency, and test-retest reliability. Results. All MAPS Questionnaire dimensions demonstrated strong validity and reliability and demonstrated agreement over time. Conclusion. The MAPS Questionnaire includes seven dimensions and 81 items related to the MAPS conceptual model and provides a scientific, in-depth measurement tool that allows long-standing CBPR partnerships to evaluate their work toward achieving health equity.

Using a CBPR Approach to Guide Successful Recruitment for an Online Questionnaire: The Measurement Approaches to Partnership Success (MAPS) Case Study.

The Measurement Approaches to Partnership Success (MAPS) study team effectively used a community-based participatory research (CBPR) approach to recruit 55 long-standing CBPR partnerships to participate in an online questionnaire to assess factors associated with partnership success. Our recruitment was guided by interconnected values of collaboration, transparency, and relationship-building to maintain fidelity to CBPR principles throughout the process. We operationalized these values into a series of strategies to recruit partnerships and sustain their involvement, including establishing primary points of contact, offering incentives for completion, personalizing recruitment materials, and practicing flexibility in our approach. We aim to inform public health researchers on the strategies that enabled our team to achieve 100% of our study recruitment goal, with the intent that our recommendations can be applied by others to enhance their recruitment efforts and reach their data collection goals for future public health research.

The Measurement Approaches to Partnership Success (MAPS) Questionnaire and Facilitation Guide: A Validated Measure of CBPR Partnership Success.

Partnerships that effectively engage in certain key structural and process functions are more likely to meet their research goals and contribute to longer-term health equity outcomes. Ongoing evaluation of partnerships' level of achievement of these key functions, along with their fidelity to the guiding principles of community-based participatory research (CBPR), is therefore essential to understand how they can achieve desired partnership outcomes. This article describes the validated Measurement Approaches to Partnership Success (MAPS) Questionnaire and the use of an accompanying Facilitation Guide in helping members of CBPR partnerships evaluate their partnership's state of development and interpret findings to improve its structure, processes, and outcomes. We describe the conceptual framework guiding the development of the MAPS Questionnaire and its 81-item across seven key outcome dimensions, along with 28 items measuring precursor characteristics of CBPR partnership outcomes. The Facilitation Guide provides general guidelines for sharing, interpreting, and applying results within partnerships using a participatory process, definitions and items for each dimension, an example of presenting summary means, and dimension-specific reflective questions for discussion. We offer recommendations for practical uses of the MAPS Questionnaire and Facilitation Guide. Whether used as a comprehensive tool or by dimension, the MAPS Questionnaire is conceptually sound and empirically validated for evaluating how CBPR partnerships can achieve long-standing success. CBPR partnerships at any stage of development will find the MAPS Questionnaire and Facilitation Guide useful in measuring and interpreting indicators of partnership success, sharing results, and improving their ability to contribute to achieving health equity goals.

A CBPR-Enhanced Delphi Method: The Measurement Approaches to Partnership Success Case Study.

As part of a 5-year study to develop and validate an instrument for measuring success in long-standing community-based participatory research (CBPR) partnerships, we utilized the Delphi method with a panel of 16 community and academic CBPR experts to assess face and content validity of the instrument's broad concepts of success and measurement items. In addition to incorporating quantitative and qualitative feedback from two online surveys, we included a 2-day face-to-face meeting with the Expert Panel to invite open discussion and diversity of opinion in line with the CBPR principles framing and guiding the study. The face-to-face meeting allowed experts to review the survey data (with maintained anonymity), convey their perspectives, and offer interpretations that were untapped in the online surveys. Using a CBPR approach facilitated a synergistic process that moved above and beyond the consensus achieved in the initial Delphi rounds, to enhance the Delphi technique and the development of items in the instrument.

Dispersion in the hospital network of shared patients is associated with less efficient care.

BACKGROUND: There is growing recognition that health care providers are embedded in networks formed by the movement of patients between providers. However, the structure of such networks and its impact on health care are poorly understood. PURPOSE: We examined the level of dispersion of patient-sharing networks across U.S. hospitals and its association with three measures of care delivered by hospitals that were likely to relate to coordination. METHODOLOGY/APPROACH: We used data derived from 2016 Medicare Fee-for-Service claims to measure the volume of patients that hospitals treated in common. We then calculated a measure of dispersion for each hospital based on how those patients were concentrated in outside hospitals. Using this measure, we created multivariate regression models to estimate the relationship between network dispersion, Medicare spending per beneficiary, readmission rates, and emergency department (ED) throughput rates. RESULTS: In multivariate analysis, we found that hospitals with more dispersed networks (those with many low-volume patient-sharing relationships) had higher spending but not greater readmission rates or slower ED throughput. Among hospitals with fewer resources, greater dispersion related to greater readmission rates and slower ED throughput. Holding an individual hospital's dispersion constant, the level of dispersion of other hospitals in the hospital's network was also related to these outcomes. CONCLUSION: Dispersed interhospital networks pose a challenge to coordination for patients who are treated at multiple hospitals. These findings indicate that the patient-sharing network structure may be an overlooked factor that shapes how health care organizations deliver care. PRACTICE IMPLICATIONS: Hospital leaders and hospital-based clinicians should consider how the structure of relationships with other hospitals influences the coordination of patient care. Effective management of this broad network may lead to important strategic partnerships.

Application of Mixed Methods in Health Services Management Research: A Systematic Review.

Mixed methods research (MMR) is versatile, pragmatic, and adaptable to constraints and opportunities during a research process. Although MMR has gain popularity in health services management research, little is known about how the research approach has been used and the quality of research. We conducted a systematic review of 198 MMR articles published in selected U.S.-based and international health services management journals from 2000 through 2018 to examine the extent of MMR application and scientific rigor. Results showed limited, yet increasing, use of MMR and a high degree of correspondence between MMR designs and study purposes. However, most articles did not clearly justify using MMR designs and the reporting of method details and research integration were inadequate in a significant portion of publications. We propose a checklist to assist the preparation and review of MMR manuscripts. Additional implications and recommendations to improve transparency, rigor, and quality in MMR are discussed.

A retrospective comparison of guidelines to assess hospital-diagnosed urinary tract infection in nursing home residents.

BACKGROUND: Inappropriate antibiotic treatments for urinary tract infection (UTI) in nursing home (NH) residents are common and contribute to antibiotic resistance. Published guidelines aim to improve accurate assessment, diagnosis, and treatment of UTIs. This study assessed whether records from hospitalized NH residents diagnosed with UTI, while comparing the Cooper Tool and Stone criteria, supported appropriate treatment. METHODS: A retrospective chart review was conducted using electronic medical record (EMR) data from residents of 3 NHs who were diagnosed with UTI when hospitalized over a 3-year period. The Cooper Tool and Stone criteria were used to assess treatment appropriateness. RESULTS: Of 79 hospitalized residents treated for UTI, 11 (13.9%) were appropriately treated according to the Cooper Tool and 9 (11.4%) according to Stone. The 2 criteria agreed in 9 of the cases including 100% of those with catheters. Urinalysis was documented in 72% of residents and 24% had documentation of culture and sensitivity. CONCLUSIONS: Appropriate UTI treatment rates using both tools were low but much higher in those with catheters. Future research is necessary to validate the use of these tools in the hospital setting which have the potential to improve treatment accuracy and reduce unnecessary antibiotics use.

Can Collaboration Between Nonprofit Hospitals and Local Health Departments Influence Population Health Investments by Nonprofit Hospitals?

BACKGROUND: The patient protection and Affordable Care Act (ACA) sought to improve population health by requiring nonprofit hospitals (NFPs) to conduct triennial community health needs assessments and address the identified needs. In this context, some states have encouraged collaboration between hospitals and local health department (LHD) to increase the focus of community benefit spending onto population health. OBJECTIVES: The aim was to examine whether a 2012 state law that required NFPs to collaborate with LHDs in local health planning influenced hospital population health improvement spending. RESEARCH DESIGN: We merged Internal Revenue Service data on NFP community benefit spending with data on hospital, county and state-level characteristics and estimated a difference-in-differences specification of hospital population health spending in 2009-2016 that compared the difference between hospitals that were required to collaborate with LHDs to those that were not, before and after the requirement. MEASURES: The primary outcome was population health spending divided by operating expenses. RESULTS: We found that the requirement for hospital-LHD collaboration was associated with increased mean population health spending of ∼$393,000-$786,000 (P=0.03). This association was significant in 2015-2016, perhaps reflecting the lag between assessments and implementation. Urban hospitals were responsible for most of the increased spending. CONCLUSIONS: Policymakers have sought to encourage hospitals to increase their investment in population health; however, overall community benefit spending on population health has remained flat. We found that requiring hospital-LHD collaboration was associated with increased hospital investment in population health. It may be that hospitals increase population health spending because collaboration improves expected effectiveness or increases hospital accountability.

Targeting Patient and Health System Barriers To Improve Rates of Hemodialysis Initiation with an Arteriovenous Access.

Background: Guidelines recommend pre-emptive creation of arteriovenous (AV) access. However, <20% of US patients initiate hemodialysis (HD) with a functional AV access. We implemented a quality improvement (QI) program to improve pre-HD vascular access care. Methods: After conducting qualitative research with key informants, we implemented a 7-month vascular access support QI program at Geisinger Health. The program targeted patient and health system barriers to AV access through education, needs assessment, peer support, care navigation, and electronic supports. We performed pre-, intra-, and postprogram stakeholder interviews to identify program barriers and facilitators and to assess acceptability. In a research substudy, we compared pre- and postprogram self-efficacy, knowledge, and confidence navigating vascular access care. Results: There were 37 patient and 32 clinician/personnel participants. Of the 37 patients, 34 (92%) completed vascular access-specific education, 33 (89%) underwent needs assessment, eight (22%) engaged with peer mentors, 21 (57%) had vein mapping, 18 (49%) had an initial surgical appointment, 15 (40%) underwent AV access surgery, and six (16%) started HD during the 7-month program. Qualitative findings demonstrated program acceptability to participants and suggested that education provision and emotional barrier identification were important to engaging patients in vascular access care. Research findings showed pre- to postprogram improvements in patient self-efficacy (28.1-30.8, P=0.05) and knowledge (4.9-6.9, P=0.004), and trends toward improvements in confidence among patients (8.0-8.7, P=0.2) and providers (7.5-7.8, P=0.1). Conclusions: Our intervention targeting patient and health system barriers improved patient vascular access knowledge and self-efficacy.

Trends in Regional Supply of Peritoneal Dialysis in an Era of Health Reform, 2006 to 2013.

Peritoneal dialysis (PD), a home-based treatment for kidney failure, is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis. Yet <10% of patients receive PD. Access to this alternative treatment, vis-à-vis providers' supply of PD services, may be an important factor but has been sparsely studied in the current era of national payment reform for dialysis care. We describe temporal and regional variation in PD supply among Medicare-certified dialysis facilities from 2006 to 2013. The average proportion of facilities offering PD per hospital referral region increased from 40% (2006) to 43% (2013). PD supply was highest in hospital referral regions with higher percentage of facilities in urban areas (p = .004), prevalence of PD use (p < .0001), percentage of White end-stage renal disease patients (p = .02), and per capita income (p = .02). Disparities in PD access persist in rural, non-White, and low-income regions. Policy efforts to further increase regional PD supply should focus on these underserved communities.

Comparing Mortality of Peritoneal and Hemodialysis Patients in an Era of Medicare Payment Reform.

BACKGROUND: Prior studies have shown peritoneal dialysis (PD) patients to have lower or equivalent mortality to patients who receive in-center hemodialysis (HD). Medicare's 2011 bundled dialysis prospective payment system encouraged expansion of home-based PD with unclear impacts on patient outcomes. This paper revisits the comparative risk of mortality between HD and PD among patients with incident end-stage kidney disease initiating dialysis in 2006-2013. RESEARCH DESIGN: We conducted a retrospective cohort study comparing 2-year all-cause mortality among patients with incident end-stage kidney disease initiating dialysis via HD and PD in 2006-2013, using data from the US Renal Data System and Medicare. Analysis was conducted using Cox proportional hazards models fit with inverse probability of treatment weighting that adjusted for measured patient demographic and clinical characteristics and dialysis market characteristics. RESULTS: Of the 449,652 patients starting dialysis between 2006 and 2013, the rate of PD use in the first 90 days increased from 9.3% of incident patients in 2006 to 14.2% in 2013. Crude 2-year mortality was 27.6% for patients dialyzing via HD and 16.7% for patients on PD. In adjusted models, there was no evidence of mortality differences between PD and HD before and after bundled payment (hazard ratio, 0.96; 95% confidence interval, 0.89-1.04; P=0.33). CONCLUSIONS: Overall mortality for HD and PD use was similar and mortality differences between modalities did not change before versus after the 2011 Medicare dialysis bundled payment, suggesting that increased use of home-based PD did not adversely impact patient outcomes.

Measurement Approaches to Partnership Success: Theory and Methods for Measuring Success in Long-Standing Community-Based Participatory Research Partnerships.

BACKGROUND: Numerous conceptual frameworks have been developed to understand how community-based participatory research (CBPR) partnerships function, and multiple measurement approaches have been designed to evaluate them. However, most measures are not validated, and have focused on new partnerships. To define and assess the meaning of success in long-standing CBPR partnerships, we are conducting a CBPR study, Measurement Approaches to Partnership Success (MAPS). In this article we describe the theoretical underpinnings and methodological approaches used. OBJECTIVES: The objectives of this study are to 1) develop a questionnaire to evaluate success in long-standing CBPR partnerships, 2) test the psychometric qualities of the questionnaire, 3) assess the relationships between key variables and refine the questionnaire and theoretical model, and 4) develop mechanisms and a feedback tool to apply partnership evaluation findings. METHODS: Methodological approaches have included: engaged a community-academic national Expert Panel; conducted key informant interviews with Expert Panel; conducted a scoping literature review; conducted a Delphi process with the Expert Panel; and revised the measurement instrument. Additional methods include: conduct cognitive interviews and pilot testing; revise and test final version of the questionnaire with long-standing CBPR partnerships; examine the reliability and validity; analyze the relationship among variables in the framework; revise the framework; and develop a feedback mechanism for sharing partnership evaluation results. CONCLUSIONS: Through the application of a theoretical model and multiple methodological approaches, the MAPS study will result in a validated measurement instrument and will develop procedures for effectively feeding back evaluation findings in order to strengthen authentic partnerships to achieve health equity.

Supply and Distribution of Vascular Access Physicians in the United States: A Cross-Sectional Study.

BACKGROUND: Because functioning permanent vascular access (arteriovenous fistula [AVF] or arteriovenous graft [AVG]) is crucial for optimizing patient outcomes for those on hemodialysis, the supply of physicians placing vascular access is key. We investigated whether area-level demographic and healthcare market attributes were associated with the distribution and supply of AVF/AVG access physicians in the United States. METHODS: A nationwide registry of physicians placing AVFs/AVGs in 2015 was created using data from the United States Renal Data System and the American Physician Association's Physician Masterfile. We linked the registry information to the Area Health Resource File to assess the supply of AVF/AVG access physicians and their professional attributes by hospital referral region (HRR). Bivariate analysis and Poisson regression were performed to examine the relationship between AVF/AVG access physician supply and demographic, socioeconomic, and health resource conditions of HRRs. The setting included all 50 states. The main outcome was supply of AVF/AVG access physicians, defined as the number of physicians performing AVF and/or AVG placement per 1000 prevalent patients with ESKD. RESULTS: The majority of vascular access physicians were aged 45-64 (average age, 51.6), male (91%), trained in the United States (76%), and registered in a surgical specialty (74%). The supply of physicians varied substantially across HRRs. The supply was higher in HRRs with a higher percentage white population (ß=0.44; SEM=0.14; P=0.002), lower unemployment rates (ß=-10.74; SEM=3.41; P=0.002), and greater supply of primary care physicians (ß=0.18; SEM=0.05; P=0.001) and nephrologists (ß=15.89; SEM=1.22; P<0.001). CONCLUSIONS: Geographic variation was observed in the supply of vascular access physicians. Higher supply of such specialist physicians in socially and economically advantaged areas may explain disparities in vascular access and outcomes in the United States and should be the subject of further study and improvement.

Trends in Peritoneal Dialysis Use in the United States after Medicare Payment Reform.

BACKGROUND AND OBJECTIVES: Peritoneal dialysis (PD) for ESKD is associated with similar mortality, higher quality of life, and lower costs compared with hemodialysis (HD), but has historically been underused. We assessed the effect of the 2011 Medicare prospective payment system (PPS) for dialysis on PD initiation, modality switches, and stable PD use. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Using US Renal Data System and Medicare data, we identified all United States patients with ESKD initiating dialysis before (2006-2010) and after (2011-2013) PPS implementation, and observed their modality for up to 2 years after dialysis initiation. Using logistic regression models, we examined the associations between PPS and early PD experience (any PD 1-90 days after initiation), late PD use (any PD 91-730 days after initiation), and modality switches (PD-to-HD or HD-to-PD 91-730 days after initiation). We adjusted for patient, dialysis facility, and regional characteristics. RESULTS: Overall, 619,126 patients with incident ESKD received dialysis at Medicare-certified facilities, 2006-2013. Observed early PD experience increased from 9.4% before PPS to 12.6% after PPS. Observed late PD use increased from 12.1% to 16.1%. In adjusted analyses, PPS was associated with increased early PD experience (odds ratio [OR], 1.51; 95% confidence interval [95% CI], 1.47 to 1.55; P<0.001) and late PD use (OR, 1.47; 95% CI, 1.45 to 1.50; P<0.001). In subgroup analyses, late PD use increased in part due to an increase in HD-to-PD switches among those without early PD experience (OR, 1.59; 95% CI, 1.52 to 1.66; P<0.001) and a decrease in PD-to-HD switches among those with early PD experience (OR, 0.92; 95% CI, 0.87 to 0.98; P=0.004). CONCLUSIONS: More patients started, stayed on, and switched to PD after dialysis payment reform. This occurred without a substantial increase in transfers to HD.

Effect of a community-based participatory health literacy program on health behaviors and health empowerment among community-dwelling older adults: A quasi-experimental study.

This study evaluated the effect of a community-based participatory health literacy program aimed at improving the health behaviors and health empowerment for older adults. A two-group pretest and posttest quasi-experimental design with surveys conducted at baseline (T1), immediately after the intervention (T2), and 6 months after the intervention (T3). The intervention group (n = 94) attended a 12-week health literacy program; while the comparison group (n = 78) did not. The results demonstrated that intervention group had significantly better health behavior practices for weight control (OR = 3.71, 95% CI = 1.59-8.64), regular exercise (OR = 15.26, 95% CI = 1.92-121.13), and health information navigation (OR = 2.61, 95% CI = 1.16-5.84). Health empowerment was significantly higher in the intervention group than the comparison group (p < 0.01).This study suggests that integrating community-based participatory design is effective in improving some health behaviors and health empowerment in older adults over a short period.

Patient Satisfaction Is Associated With Dialysis Facility Quality and Star Ratings.

The Dialysis Facility Compare Star Rating and the Quality Incentive Program (QIP) generate separate performance scores from clinical measures, and the In-Center Hemodialysis Consumer Assessment of Healthcare Providers and Systems (ICH-CAHPS) survey evaluates patient satisfaction across 6 separate domains related to nephrologists, dialysis facility, and information transmission. This study examined the relationship of the 3 measures for US clinics, modeling the 6 ICH-CAHPS domains as independent variables and QIP and star ratings as dependent variables. Among 3176 dialysis clinics, domains assessing dialysis facility and information transmission had a consistently stronger relationship with QIP and star ratings than the domains assessing nephrologists: QIP, ß (95% CI) = 1.62 (1.26-1.97) for dialysis facility staff rating, 0.70 (0.35-1.05) for nephrologists; star rating, odds ratio (95% CI) = 1.38 (1.29-1.49) for dialysis facility staff rating, 1.17 (1.09-1.25) for nephrologists. Patient satisfaction is associated with dialysis care quality, with surprising differences between nephrologists and dialysis facilities.

Medicare's New Prospective Payment System on Facility Provision of Peritoneal Dialysis.

BACKGROUND AND OBJECTIVES: Peritoneal dialysis is a self-administered, home-based treatment for ESKD associated with equivalent mortality, higher quality of life, and lower costs compared with hemodialysis. In 2011, Medicare implemented a comprehensive prospective payment system that makes a single payment for all dialysis, medication, and ancillary services. We examined whether the prospective payment system increased dialysis facility provision of peritoneal dialysis services and whether changes in peritoneal dialysis provision were more common among dialysis facilities that are chain affiliated, located in nonurban areas, and in regions with high dialysis market competition. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a longitudinal retrospective cohort study of n=6433 United States nonfederal dialysis facilities before (2006-2010) and after (2011-2013) the prospective payment system using data from the US Renal Data System, Medicare, and Area Health Resource Files. The outcomes of interest were a dichotomous indicator of peritoneal dialysis service availability and a discrete count variable of dialysis facility peritoneal dialysis program size defined as the annual number of patients on peritoneal dialysis in a facility. We used general estimating equation models to examine changes in peritoneal dialysis service offerings and peritoneal dialysis program size by a pre- versus post-prospective payment system effect and whether changes differed by chain affiliation, urban location, facility size, or market competition, adjusting for 1-year lagged facility-, patient with ESKD-, and region-level demographic characteristics. RESULTS: We found a modest increase in observed facility provision of peritoneal dialysis and peritoneal dialysis program size after the prospective payment system (36% and 5.7 patients in 2006 to 42% and 6.9 patients in 2013, respectively). There was a positive association of the prospective payment system with peritoneal dialysis provision (odds ratio, 1.20; 95% confidence interval, 1.13 to 1.18) and PD program size (incidence rate ratio, 1.27; 95% confidence interval, 1.22 to 1.33). Post-prospective payment system change in peritoneal dialysis provision was greater among nonurban (P<0.001), chain-affiliated (P=0.002), and larger-sized facilities (P<0.001), and there were higher rates of peritoneal dialysis program size growth in nonurban facilities (P<0.001). CONCLUSIONS: Medicare's 2011 prospective payment system was associated with more facilities' availability of peritoneal dialysis and modest growth in facility peritoneal dialysis program size.
