Implications of reassigning patients for the medical home: a case study

Patient Health Outcomes following Dialysis Facility Closures in the United States

BACKGROUND

Ongoing changes to reimbursement of United States dialysis care may increase the risk of dialysis facility closures. Closures may be particularly detrimental to the health of patients receiving dialysis, who are medically complex and clinically tenuous.

METHODS

We used two separate analytic strategies-one using facility-based matching and the other using propensity score matching-to compare health outcomes of patients receiving in-center hemodialysis at United States facilities that closed with outcomes of similar patients who were unaffected. We used negative binomial and Cox regression models to estimate associations of facility closure with hospitalization and mortality in the subsequent 180 days.

RESULTS

We identified 8386 patients affected by 521 facility closures from January 2001 through April 2014. In the facility-matched model, closures were associated with 9% higher rates of hospitalization (relative rate ratio [RR], 1.09; 95% confidence interval [95% CI], 1.03 to 1.16), yielding an absolute annual rate difference of 1.69 hospital days per patient-year (95% CI, 0.45 to 2.93). Similarly, in a propensity-matched model, closures were associated with 7% higher rates of hospitalization (RR, 1.07; 95% CI, 1.00 to 1.13; P=0.04), yielding an absolute rate difference of 1.08 hospital days per year (95% CI, 0.04 to 2.12). Closures were associated with nonsignificant increases in mortality (hazard ratio [HR], 1.08; 95% CI, 1.00 to 1.18; P=0.05 for the facility-matched comparison; HR, 1.08; 95% CI, 0.99 to 1.17; P=0.08 for the propensity-matched comparison).

CONCLUSIONS

Patients affected by dialysis facility closures experienced increased rates of hospitalization in the subsequent 180 days and may be at increased risk of death. This highlights the need for effective policies that continue to mitigate risk of facility closures.

Specialized primary care medical home: A positive impact on continuity of care among autistic adults

LAY ABSTRACT

There is a nationally recognized need for innovative healthcare delivery models to improve care continuity for autistic adults as they age out of pediatric and into adult healthcare systems. One possible model of care delivery is called the "medical home". The medical home is not a residential home, but a system where a patient's healthcare is coordinated through a primary care physician to ensure necessary care is received when and where the patient needs it. We compared the continuity of care among autistic adult patients at a specialized primary care medical home designed to remove barriers to care for autistic adults, called the CAST, to matched national samples of autistic adults with private insurance or Medicare. Continuity of primary care among CAST patients was significantly better than that of matched national samples of autistic adult Medicare beneficiaries and similar to that of privately insured autistic adults. Our findings suggest that medical homes, like CAST, are a promising solution to improve healthcare delivery for the growing population of autistic adults.

Mixed method evaluation of Relational Team Development (RELATED) to improve team-based care for complex patients with mental illness in primary care

BACKGROUND

Patients with mental illness are frequently treated in primary care, where Primary Care Providers (PCPs) report feeling ill-equipped to manage their care. Team-based models of care improve outcomes for patients with mental illness, but multiple barriers limit adoption. Barriers include practical issues and psychosocial factors associated with the reorganization of care. Practice facilitation can improve implementation, but does not directly address the psychosocial factors or gaps in PCP skills in managing mental illness. To address these gaps, we developed Relational Team Development (RELATED).

METHODS

RELATED is an implementation strategy combining practice facilitation and psychology clinical supervision methodologies to improve implementation of team-based care. It includes PCP-level clinical coaching and a team-level practice change activity. We performed a preliminary assessment of RELATED with a convergent parallel mixed method study in 2 primary care clinics in an urban Federally Qualified Health Center in Southwest, USA, 2017-2018. Study participants included PCPs, clinic staff, and patient representatives. Clinic staff and patients were recruited for the practice change activity only. Primary outcomes were feasibility and acceptability. Feasibility was assessed as ease of recruitment and implementation. Acceptability was measured in surveys of PCPs and staff and focus groups. We conducted semi-structured focus groups with 3 participant groups in each clinic: PCPs; staff and patients; and leadership. Secondary outcomes were change in pre- post- intervention PCP self-efficacy in mental illness management and team-based care. We conducted qualitative observations to better understand clinic climate.

RESULTS

We recruited 18 PCPs, 17 staff members, and 3 patient representatives. We ended recruitment early due to over recruitment. Both clinics developed and implemented practice change activities. The mean acceptability score was 3.7 (SD=0.3) on a 4-point Likert scale. PCPs had a statistically significant increase in their mental illness management self-efficacy [change = 0.9, p-value= <.01]. Focus group comments were largely positive, with PCPs requesting additional coaching.

CONCLUSIONS

RELATED was feasible and highly acceptable. It led to positive changes in PCP self-efficacy in Mental Illness Management. If confirmed as an effective implementation strategy, RELATED has the potential to significantly impact implementation of evidence-based interventions for patients with mental illness in primary care.

Designing the relational team development intervention to improve management of mental health in primary care using iterative stakeholder engagement

BACKGROUND

Team-based models of care are efficacious in improving outcomes for patients with mental and physical illnesses. However, primary care clinics have been slow to adopt these models. We used iterative stakeholder engagement to develop an intervention to improve the implementation of team-based care for this complex population.

METHODS

We developed the initial framework for Relational Team Development (RELATED) from a qualitative study of Primary Care Providers' (PCPs') experiences treating mental illness and a literature review of practice facilitation and psychology clinical supervision. Subsequently, we surveyed 900 Colorado PCPs to identify factors associated with PCP self-efficacy in management of mental illness and team-based care. We then conducted two focus groups for feedback on RELATED. Lastly, we convened an expert panel to refine the intervention.

RESULTS

We developed RELATED, a two-part intervention delivered by a practice facilitator with a background in clinical psychology. The facilitator observes PCPs during patient visits and provides individualized coaching. Next, the facilitator guides the primary care team through a practice change activity with a focus on relational team dynamics.

CONCLUSION

The iterative development of RELATED using stakeholder engagement offers a model for the development of interventions tailored to the needs of these stakeholders.

Review of patient-reported experience within Patient-Centered Medical Homes: insights for Australian Health Care Homes

Understanding patient experience is necessary to advance the patient-centred approach to health service delivery. Australia's primary healthcare model, the 'Health Care Home', is based on the 'Patient-Centered Medical Home' (PCMH) model developed in the United States. Both these models aim to improve patient experience; however, the majority of existing PCMH model evaluations have focussed on funding, management and quality assurance measures. This review investigated the scope of evidence reported by adult patients using a PCMH. Using a systematic framework, the review identified 39 studies, sourced from 33 individual datasets, which used both quantitative and qualitative approaches. Patient experience was reported for model attributes, including the patient-physician and patient-practice relationships; care-coordination; access to care; and, patient engagement, goal setting and shared decision-making. Results were mixed, with the patient experience improving under the PCMH model for some attributes, and some studies indicating no difference in patient experience following PCMH implementation. The scope and quality of existing evidence does not demonstrate improvement in adult patient experience when using the PCMH. Better measures to evaluate patient experience in the Australian Health Care Home model are required.

A clustered controlled trial of the implementation and effectiveness of a medical home to improve health care of people with serious mental illness: study protocol

BACKGROUND

People with serious mental illness (SMI) die many years prematurely, with rates of premature mortality two to three times greater than the general population. Most premature deaths are due to "natural causes," especially cardiovascular disease and cancer. Often, people with SMI are not well engaged in primary care treatment and do not receive high-value preventative and medical services. There have been numerous efforts to improve this care, and few controlled trials, with inconsistent results. While people with SMI often do poorly with usual primary care arrangements, research suggests that integrated care and medical care management may improve treatment and outcomes, and reduce treatment costs.

METHODS

This hybrid implementation-effectiveness study is a prospective, cluster controlled trial of a medical home, the SMI Patient-Aligned Care Team (SMI PACT), to improve the healthcare of patients with SMI enrolled with the Veterans Health Administration. The SMI PACT team includes proactive medical nurse care management, and integrated mental health treatment through regular psychiatry consultation and a collaborative care model. Patients are recruited to receive primary care through SMI PACT based on having a serious mental illness that is manageable with treatment, and elevated risk for hospitalization or death. In a site-level prospective controlled trial, this project studies the effect, relative to usual care, of SMI PACT on provision of appropriate preventive and medical treatments, health-related quality of life, satisfaction with care, and medical and mental health treatment utilization and costs. Research includes mixed-methods formative evaluation of usual care and SMI PACT implementation to strengthen the intervention and assess barriers and facilitators. Investigators examine relationships among organizational context, intervention factors, and patient and clinician outcomes, and identify patient factors related to successful patient outcomes.

DISCUSSION

This will be one of the first controlled trials of the implementation and effectiveness of a patient centered medical home for people with serious mental illness. It will provide information regarding the value of this strategy, and processes and tools for implementing this model in community healthcare settings.

Do Patient-Centered Medical Homes Improve Health Behaviors, Outcomes, and Experiences of Low-Income Patients? A Systematic Review and Meta-Analysis

OBJECTIVES

To examine: (1) what elements of patient-centered medical homes (PCMHs) are typically provided to low-income populations, (2) whether PCMHs improve health behaviors, experiences, and outcomes for low-income groups.

DATA SOURCES/STUDY SETTING

Existing literature on PCMH utilization among health care organizations serving low-income populations.

STUDY DESIGN

Systematic review and meta-analysis.

DATA COLLECTION/EXTRACTION METHODS

We obtained papers through existing systematic and literature reviews and via PubMed, Web of Science, and the TRIP databases, which examined PCMHs serving low-income populations. A total of 434 studies were reviewed. Thirty-three articles met eligibility criteria.

PRINCIPAL FINDINGS

Patient-centered medical home interventions usually were composed of five of the six recommended components. Overall positive effect of PCMH interventions was d = 0.247 (range -0.965 to 1.42). PCMH patients had better clinical outcomes (d = 0.395), higher adherence (0.392), and lower utilization of emergency rooms (d = -0.248), but there were apparent limitations in study quality.

CONCLUSIONS

Evidence shows that the PCMH model can increase health outcomes among low-income populations. However, limitations to quality include no assessment for confounding variables. Implications are discussed.

Effects of New Funding Models for Patient-Centered Medical Homes on Primary Care Practice Finances and Services: Results of a Microsimulation Model

PURPOSE

We assess the financial implications for primary care practices of participating in patient-centered medical home (PCMH) funding initiatives.

METHODS

We estimated practices' changes in net revenue under 3 PCMH funding initiatives: increased fee-for-service (FFS) payments, traditional FFS with additional per-member-per-month (PMPM) payments, or traditional FFS with PMPM and pay-for-performance (P4P) payments. Net revenue estimates were based on a validated microsimulation model utilizing national practice surveys. Simulated practices reflecting the national range of practice size, location, and patient population were examined under several potential changes in clinical services: investments in patient tracking, communications, and quality improvement; increased support staff; altered visit templates to accommodate longer visits, telephone visits or electronic visits; and extended service delivery hours.

RESULTS

Under the status quo of traditional FFS payments, clinics operate near their maximum estimated possible net revenue levels, suggesting they respond strongly to existing financial incentives. Practices gained substantial additional net annual revenue per full-time physician under PMPM or PMPM plus P4P payments ($113,300 per year, 95% CI, $28,500 to $198,200) but not under increased FFS payments (-$53,500, 95% CI, -$69,700 to -$37,200), after accounting for costs of meeting PCMH funding requirements. Expanding services beyond minimum required levels decreased net revenue, because traditional FFS revenues decreased.

CONCLUSIONS

PCMH funding through PMPM payments could substantially improve practice finances but will not offer sufficient financial incentives to expand services beyond minimum requirements for PCMH funding.

Medicare Chronic Care Management Payments and Financial Returns to Primary Care Practices: A Modeling Study

BACKGROUND

Physicians have traditionally been reimbursed for face-to-face visits. A new non-visit-based payment for chronic care management (CCM) of Medicare patients took effect in January 2015.

OBJECTIVE

To estimate financial implications of CCM payment for primary care practices.

DESIGN

Microsimulation model incorporating national data on primary care use, staffing, expenditures, and reimbursements.

DATA SOURCES

National Ambulatory Medical Care Survey and other published sources.

TARGET POPULATION

Medicare patients.

TIME HORIZON

10 years.

PERSPECTIVE

Practice-level.

INTERVENTION

Comparison of CCM delivery approaches by staff and physicians.

OUTCOME MEASURES

Net revenue per full-time equivalent (FTE) physician; time spent delivering CCM services.

RESULTS OF BASE-CASE ANALYSIS

If nonphysician staff were to deliver CCM services, net revenue to practices would increase despite opportunity and staffing costs. Practices could expect approximately $332 per enrolled patient per year (95% CI, $234 to $429) if CCM services were delivered by registered nurses (RNs), approximately $372 (CI, $276 to $468) if services were delivered by licensed practical nurses, and approximately $385 (CI, $286 to $485) if services were delivered by medical assistants. For a typical practice, this equates to more than $75 ,00 of net annual revenue per FTE physician and 12 hours of nursing service time per week if 50% of eligible patients enroll. At a minimum, 131 Medicare patients (CI, 115 to 140 patients) must enroll for practices to recoup the salary and overhead costs of hiring a full-time RN to provide CCM services.

RESULTS OF SENSITIVITY ANALYSIS

If physicians were to deliver all CCM services, approximately 25% of practices nationwide could expect net revenue losses due to opportunity costs of face-to-face visit time.

LIMITATION

The CCM program may alter long-term primary care use, which is difficult to predict.

CONCLUSION

Practices that rely on nonphysician team members to deliver CCM services will probably experience substantial net revenue gains but must enroll a sufficient number of eligible patients to recoup costs.

PRIMARY FUNDING SOURCE

None.

Assessing patient experiences in the pediatric patient-centered medical home: a comparison of two instruments

The Patient-Centered Medical Home (PCMH) is a model of care that has been promoted as a way to transform a broken primary care system in the US. However, in order to convince more practices to make the transformation and to properly reimburse practices who are PCMHs, valid and reliable data are needed. Data that capture patient experiences in a PCMH is valuable, but which instrument should be used remains unclear. Our study aims to compare the validity and reliability of two national PCMH instruments. Telephone surveys were conducted with children who receive care from 20 pediatric practices across Florida (n = 990). All of the children are eligible for Medicaid or the Children's Health Insurance Program. Analyses were conducted to compare the Consumer Assessment of Health Plan Survey-Patient-Centered Medical Home (CAHPS-PCMH) and the National Survey of Children with Special Health Care Needs (NS-CSHCN) medical home domain. Respondents were mainly White non-Hispanic, female, under 35 years old, and from a two-parent household. The NS-CSHCN outperformed the CAHPS-PCMH in regard to scale reliability (Cronbach's alpha coefficients all ≥0.81 vs. 0.56-0.85, respectively). In regard to item-domain convergence and discriminant validity the CAHPS-PCMH fared better than the NS-CSHCN (range of convergence 0.66-0.93 vs. 0.32-1.00). The CAHPS-PCMH did not correspond to the scale structure in construct validity testing. Neither instrument performed well in the known-groups validity tests. No clear best instrument was determined. Further revision and calibration may be needed to accurately assess patient experiences in the PCMH.

The patient-centered medical home: an evaluation of a single private payer demonstration in New Jersey

BACKGROUND

The patient-centered medical home (PCMH) has increasingly been looked to by policy makers, health care providers, and private insurers as a potential solution to the fragmented and inefficient US health care system. Whether the PCMH achieves these goals is not known.

OBJECTIVES

To evaluate a PCMH demonstration project implemented in 2011 in 8 New Jersey primary care practices covering over 10,000 plan members.

RESEARCH DESIGN

We conduct difference-in-differences analysis, comparing changes in outcomes at 8 medical home practices to a group of 24 comparison practices before (2010) and after (2011) the medical home implementation occurred. We use Mahalanobis distance matching to select the 24 comparison practices, matching on practice characteristics. We focus on the effect of the PCMH pilot on 3 groups of outcomes: health care utilization, costs, and quality.

RESULTS

The study cohort included 35,059 members during the study period 2010-2011-10,004 in the 8 PCMH practices and 25,055 in the 24 comparison practices. Health care utilization and costs did not significantly change with adoption of the PCMH model. In testing for changes in Healthcare Effectiveness and Data Information Set (HEDIS) quality measures, rates of mammography increased in PCMH practices after PCMH implementation compared to non-PCMH practices, by 2.2 percentage points on a base of 69.5% (P<0.001). Rates of nephropathy screening also increased (by 6.6 percentage points on a base of 51.8%; P=0.05). Changes in 7 other HEDIS quality measures following PCMH implementation were not statistically significant.

CONCLUSIONS

We find little evidence of reductions in health care utilization or cost and minimal evidence of improvements in quality of care. Ongoing work is needed to understand why this model of care seems to work in some cases and not others and to evaluate how to improve the medical home.

Conformity of pediatric/adolescent HIV clinics to the patient-centered medical home care model

The patient-centered medical home (PCMH) has been introduced as a model for providing high-quality, comprehensive, patient-centered care that is both accessible and coordinated, and may provide a framework for optimizing the care of youth living with HIV (YLH). We surveyed six pediatric/adolescent HIV clinics caring for 578 patients (median age 19 years, 51% male, and 82% black) in July 2011 to assess conformity to the PCMH. Clinics completed a 50-item survey covering the six domains of the PCMH: (1) comprehensive care, (2) patient-centered care, (3) coordinated care, (4) accessible services, (5) quality and safety, and (6) health information technology. To determine conformity to the PCMH, a novel point-based scoring system was devised. Points were tabulated across clinics by domain to obtain an aggregate assessment of PCMH conformity. All six clinics responded. Overall, clinics attained a mean 75.8% [95% CI, 63.3-88.3%] on PCMH measures-scoring highest on patient-centered care (94.7%), coordinated care (83.3%), and quality and safety measures (76.7%), and lowest on health information technology (70.0%), accessible services (69.1%), and comprehensive care (61.1%). Clinics moderately conformed to the PCMH model. Areas for improvement include access to care, comprehensive care, and health information technology. Future studies are warranted to determine whether greater clinic PCMH conformity improves clinical outcomes and cost savings for YLH.

The patient-centered medical home: a review of recent research

The patient-centered medical home is an important innovation in health care delivery. There is a need to assess the scope and substance of published research on medical homes. This article reviews published evaluations of medical home care for the period 2007 to 2010. Chief findings from these evaluations as a whole include associations between the provision of medical home care and improved quality, in addition to decreased utilization associated with medical home care in high-cost areas such as emergency department use. However, fewer associations were found across evaluations between medical home care and enhanced patient or family experiences. The early medical home research appears to reflect both the wide variation in how medical homes are being designed and implemented in practice and in how researchers are choosing to evaluate patient-centered medical home design and implementation. While some aspects of medical home care show promise, continued evolution of medical home evaluative research is needed.

The changes involved in patient-centered medical home transformation

In 2007, the major primary care professional societies collaboratively introduced a new model of primary care: the patient-centered medical home (PCMH). The published document outlines the basic attributes and expectations of a PCMH but not with the specificity needed to help interested clinicians and administrators make the necessary changes to their practice. To identify the specific changes required to become a medical home, the authors reviewed literature and sought the opinions of two multi-stakeholder groups. This article describes the eight consensus change concepts and 32 key changes that emerged from this process, and the evidence supporting their inclusion.

Impact on seniors of the patient-centered medical home: evidence from a pilot study

PURPOSE

To assess the impact on health care cost and quality among seniors of a patient-centered medical home (PCMH) pilot at Group Health Cooperative, an integrated health care system in Washington State.

DESIGN AND METHODS

A prospective before-and-after evaluation of the experience of seniors receiving primary care services at 1 pilot clinic compared with seniors enrolled at the remaining 19 primary care clinics owned and operated by Group Health. Analyses of secondary data on quality and cost were conducted for 1,947 seniors in the PCMH clinic and 39,396 seniors in the 19 control clinics. Patient experience with care was based on survey data collected from 487 seniors in the PCMH clinic and of 668 in 2 specific control clinics that were selected for their similarities in organization and patient composition to the pilot clinic.

RESULTS

After adjusting for baseline, seniors in the PCMH clinic reported higher ratings than controls on 3 of 7 patient experience scales. Seniors in the PCMH clinic had significantly greater quality outcomes over time, but this difference was not significant relative to control. PCMH patients used more e-mail, phone, and specialist visits but fewer emergency services and inpatient admissions for ambulatory care sensitive conditions. At 1 and 2 years, the PCMH and control clinics did not differ significantly in overall costs.

IMPLICATIONS

A PCMH redesign can be associated with improvements in patient experience and quality without increasing overall cost.
