The Medical Home Index: development and validation of a new practice-level measure of implementation of the Medical Home model

Family Experience of Caregiver Burden and Health Care Usage in a Statewide Medical Home Program

OBJECTIVE

To evaluate family-reported caregiver experiences and health care utilization of patients enrolled in the Pennsylvania Medical Home Program (PA-MHP) statewide practice network and compare results to PA-MHP practices' Medical Home Index (MHI) scores. We hypothesized families enrolled in higher-scoring patient-and-family-centered medical homes (PCMH) on completed MHIs would report decreased caregiver burden and improved health care utilization.

METHODS

We analyzed surveys completed by families receiving care coordination services in PA-MHP's network and each practice's mean MHI score. A total of 3221 caregivers completed surveys evaluating hours spent coordinating care/week, missed school/workdays, sick visits, and emergency department (ED) visits. A total of 222 providers from 54 participating PA-MHP practices completed the nationally recognized MHI. Family/practice demographics were collected. We developed multivariate logistic regression models assessing independent associations among family survey outcomes and corresponding practices' MHI scores.

RESULTS

Families enrolled in high-scoring PCMHs had decreased odds of spending >1 h/wk coordinating care (odds ratio [OR] 0.82, adjusted OR [aOR]: 0.70, 95% confidence interval [CI] 0.55-0.90), missing workdays in the past 6 months (OR 0.82, aOR: 0.72, 95% CI 0.69-0.97), and ED visits in the past 12 months (OR 0.83, aOR: 0.81, 95% CI 0.65-0.99) in comparison to families enrolled in lower-scoring PCMHs. Families enrolled in higher-scoring PCMHs did not report fewer sick visits despite fewer ED visits, indicating more appropriate health care utilization. High-scoring PCMHs had lower percentages of publicly insured and low-income children.

CONCLUSIONS

Higher-scoring PCMHs are associated with decreased caregiver burden and improved health care utilization across diverse PA practices. Future studies should evaluate interventions uniformly improving PCMH quality and equity.

Agreement of Provider and Parent Perceptions of Complex Care Medical Homes After a Care Management Intervention

INTRODUCTION

Children with medical complexity frequently lack coordinated and family-centered care and are best cared for in a medical home.

METHOD

We assessed concordance between provider and family perceptions of care management improvements during a prospective, 3-year study of nine complex care clinics and 42 primary care clinics. Using a pre-post design, we compared provider and parent perceptions of changes in care coordination and family-centered care responses using paired t tests, Spearman rank correlations, and linear regression.

RESULTS

Provider scores significantly increased in every domain (range: 14.1 points [data management], 23.0 points [chronic care management]; p < .001). Parent perceptions improved only for shared decision making improved significantly (2.2 points, p < .01).

DISCUSSION

These results indicate that it is possible to improve the medical home for children with medical complexity through a quality improvement initiative, but that provider perception of the improvement may be greater than parents' perceptions.

Characteristics of High-Performing Primary Care Pediatric Practices: A Qualitative Study

OBJECTIVE

Performance on pediatric quality measures varies across primary care practices. Health care quality is associated with organizational factors, but their effect is understudied in pediatric care. This study aimed to develop hypotheses regarding the relationship between organizational factors and composite scores on pediatric quality measures.

METHODS

Using a positive deviance approach, semistructured interviews were conducted with pediatricians and staff (N = 35) at 10 purposively selected high-performing pediatric primary care practices in Massachusetts between September and December 2016. Practices were sampled to achieve diversity in geographic location, size, and organizational structure. Interviews aimed to identify organizational strategies (eg, care processes) and contextual factors (eg, teamwork) that may be associated with performance on quality measures. Interviews were audiotaped, transcribed, and analyzed using qualitative content analytic methods.

RESULTS

We identified 4 major themes (MTs): MT1, Practice Culture; MT2, Practice Structures and Quality Improvement Tools; MT3, Attitudes and Beliefs Related to Measuring Care Quality; and MT4, Perceived Barriers to Achieving High Performance on Quality Measures. MT1 subthemes included contextual factors such as teamwork, leadership, and feeling respected as an employee. MT2 subthemes included fixed characteristics such as practice size and strategies such as the use of an electronic medical record. MT3 and MT4 subthemes linked these constructs to factors external to the practices.

CONCLUSIONS

This study suggested that elements of organizational culture may play as important a role in the quality of care delivered as specific quality improvement strategies. Interventions to further test this relationship may aid practices seeking to improve the care they deliver.

Newborn Screening Long Term Follow-Up in the Medical Home

This demonstration project explored the feasibility of utilizing data from pediatric primary care providers to evaluate the long-term outcomes of children with disorders identified by newborn screening (NBS). Compliance with national guidelines for care and the morbidity for this population was also examined. Primary care practices were recruited and patients with sickle cell disease or who were deaf/hard of hearing were given the opportunity to enroll in the study. Data were collected on the quality of the medical home with practice data compared to family responses. Clinical outcomes for each patient were assessed by review of medical records and patient surveys. These data sources were compared to determine accuracy of primary care data, morbidity, and receipt of preventive care. Electronic data sharing was explored through transmission of Clinical Document Architecture (CDA) files. Care coordination was a challenge, even in highly accredited medical homes. Providers did not have complete information regarding clinical outcomes and children were not consistently receiving recommended preventive care. Electronic data sharing with public health departments encountered interface challenges. Primary care providers in the USA should not currently be used as a sole source to evaluate long-term outcomes of children with disorders identified by NBS.

Foram identificados oito instrumentos, os quais apresentavam como características similares a abordagem na longitudinalidade, comunicação interprofissional, coordenação do cuidado, acesso aos serviços de saúde e qualidade do cuidado. Destaca-se um instrumento desenvolvido no contexto do sistema de saúde brasileiro como ferramenta útil para apoiar trabalhadores e gestores de saúde no diagnóstico situacional das potencialidades e fragilidades da Atenção Primária à Saúde e na coordenação das Redes de Atenção à Saúde.

Development and Implementation of an HIV Health Care Practice Transformation Model for Latinos

A Latino Community Health Center in Washington, D.C. implemented and evaluated a practice transformative model to optimize human resources and improve quality health outcomes in HIV service delivery for Latino patients. We conducted a qualitative formative assessment through interviews and focus groups with clinic staff and patients living with HIV/AIDS in order to inform implementation. The formative assessment identified specific training and practice facilitation needs and provided valuable insight for choosing evaluation metrics. Incorporating staff input fostered staff engagement in laying the foundation of the transformation and helped build a sense of ownership of the transformative process. Through the formative assessment process we gained insight into the organization's HIV practice and improved our ability to align practice transformation goals with evaluation metrics to better measure changes resulting from the model implementation. The formative assessment process also highlighted challenges in conducting health systems research with Latino communities in the U.S.

Association between Practice Participation in a Pediatric-focused Medical Home Learning Collaborative and Reduction of Preventable Emergency Department Visits by Publicly-insured Children in Massachusetts

Introduction:

This study evaluates the impact of practice participation in a pediatric patient-centered medical home learning collaborative on preventable emergency department (ED) visits among children in MassHealth (Massachusetts Medicaid/Children’s Health Insurance Program).

Methods:

Claims and enrollment data were extracted for child MassHealth members (aged 3–18) comprising 2 groups: members enrolled in a group of 13 child-serving practices that participated in an intensive, 29-month long patient-centered medical home learning collaborative (intervention group), and members enrolled in a group of 12 comparison practices with roughly similar panel size, type, and geographic location (comparison group). Preventable ED visits were identified using a modified version of the New York University ED algorithm. Two analyses were then conducted: (1) a repeat cross-sectional analysis among children enrolled in intervention or comparison group practices during baseline (first half of 2011) and follow-up (second half of 2013) periods; and (2) a longitudinal analysis among a subset of children enrolled for the full study period (2011–2013). Both analyses tested whether the effect of the intervention differed for children with versus without chronic conditions (effect modification).

Results:

Preventable ED visits declined from baseline to follow-up among children in both intervention and comparison practices. In the cross-sectional analysis, the decrease was the same in both practice groups, and for children with versus without chronic conditions. The longitudinal analysis shows a statistically significantly greater decrease among children with chronic conditions enrolled in the intervention practices (P = 0.02).

Conclusion:

Children with chronic conditions might receive the greatest benefit from receiving care in a medical home setting.

Indicators and Measurement Tools for Health Systems Integration: A Knowledge Synthesis

Background:

Despite far reaching support for integrated care, conceptualizing and measuring integrated care remains challenging. This knowledge synthesis aimed to identify indicator domains and tools to measure progress towards integrated care.

Methods:

We used an established framework and a Delphi survey with integration experts to identify relevant measurement domains. For each domain, we searched and reviewed the literature for relevant tools.

Findings:

From 7,133 abstracts, we retrieved 114 unique tools. We found many quality tools to measure care coordination, patient engagement and team effectiveness/performance. In contrast, there were few tools in the domains of performance measurement and information systems, alignment of organizational goals and resource allocation. The search yielded 12 tools that measure overall integration or three or more indicator domains.

Discussion:

Our findings highlight a continued gap in tools to measure foundational components that support integrated care. In the absence of such targeted tools, “overall integration” tools may be useful for a broad assessment of the overall state of a system.

Conclusions:

Continued progress towards integrated care depends on our ability to evaluate the success of strategies across different levels and context. This study has identified 114 tools that measure integrated care across 16 domains, supporting efforts towards a unified measurement framework.

Pediatric Chest Pain-Low-Probability Referral: A Multi-Institutional Analysis From Standardized Clinical Assessment and Management Plans (SCAMPs®), the Pediatric Health Information Systems Database, and the National Ambulatory Medical Care Survey

We conducted a study to assess test characteristics of red-flag criteria for identifying cardiac disease causing chest pain and technical charges of low-probability referrals. Accuracy of red-flag criteria was ascertained through study of chest pain Standardized Clinical Assessment and Management Plans (SCAMPs®) data. Patients were divided into 2 groups: Group1 (concerning clinical elements) and Group2 (without). We compared incidence of cardiac disease causing chest pain between these 2 groups. Technical charges of Group 2 were analyzed using the Pediatric Health Information System database. Potential savings for the US population was estimated using National Ambulatory Medical Care Survey data. Fifty-two percent of subjects formed Group 1. Cardiac disease causing chest pain was identified in 8/1656 (0.48%). No heart disease was identified in patients in Group 2 ( P = .03). Applying red-flags in determining need for referral identified patients with cardiac disease causing chest pain with 100% sensitivity. Median technical charges for Group 2, over a 4-year period, were US2014$775 559. Eliminating cardiac testing of low-probability referrals would save US2014$3 775 182 in technical charges annually. Red-flag criteria were an effective screen for children with chest pain. Eliminating cardiac testing in children without red-flags for referral has significant technical charge savings.

Evaluating Integrated Mental Health Care Programs for Children and Youth

Evaluations of integrated care programs share many characteristics of evaluations of other complex health system interventions. However, evaluating integrated care for child and adolescent mental health poses special challenges that stem from the broad range of social, emotional, and developmental problems that need to be addressed; the need to integrate care for other family members; and the lack of evidence-based interventions already adapted for primary care settings. Integrated care programs for children's mental health need to adapt and learn on the fly, so that evaluations may best be viewed through the lens of continuous quality improvement rather than evaluations of fixed programs.

Patient Experiences with Care Differ with Chronic Care Management in a Federally Qualified Community Health Center

This study compares patient experience among practices that vary in adoption of the chronic care management (CCM) dimension of the patient-centered medical home (PCMH) model that focuses on care coordination and management of chronic diseases. Study participants were 2903 adult patients (ages 18 years or older) at 14 primary care centers in California. Seven of the sites were classified as high (more CCM) and the other 7 low on a CCM index. Hypotheses were tested using ordinary least squares regression models. After adjusting for the number of providers at the sites, high CCM scores were associated with significantly better overall ratings of providers, provider communication, follow-up on test results, and willingness to recommend the provider (differences of 5.82, 6.85, 9.81, and 4.56, respectively on the 0-100 scale scores). The results of this study provide support for the value of the PCMH for patient experiences with care.

Outcomes for Children with Chronic Conditions Associated with Parent- and Provider-reported Measures of the Medical Home

PURPOSE

Assess relationships between having a patient-centered medical home (PCMH) and health care utilization among low-income children with chronic conditions using parent and practice perspectives.

METHODS

We analyzed data from 240 publicly insured children with chronic conditions. Parents completed surveys assessing PCMH access and their child's primary care practice completed the Medical Home Index (MHI) self-assessment. Multivariate negative binomial analyses were conducted to investigate relationships between PCMH and service use.

RESULTS

Parent-report of a usual source of care was associated with lower rates of emergency care (ED) encounters and hospitalizations. Practice report of higher organizational capacity (e.g., communication, staff education) was associated with lower rates of ED visits and hospitalizations. Parent report of a PCMH was positively associated with practice MHI score.

CONCLUSIONS

Among low-income children with chronic conditions, having a usual source of care and higher quality organizational capacity were associated with lower rates of ED visits and hospitalizations.

Multiprofessional Primary Care Units: What Affects the Clinical Performance of Italian General Practitioners?

Multiprofessional primary care models promise to deliver better care and reduce waste. This study evaluates the impact of such a model, the primary care unit (PCU), on three outcomes. A multilevel analysis within a "pre- and post-PCU" study design and a cross-sectional analysis were conducted on 215 PCUs located in the Emilia-Romagna region in Italy. Seven dimensions captured a set of processes and services characterizing a well-functioning PCU, or its degree of vitality. The impact of each dimension on outcomes was evaluated. The analyses show that certain dimensions of PCU vitality (i.e., the possibility for general practitioners to meet and share patients) can lead to better outcomes. However, dimensions related to the interaction and the joint works of general practitioners with other professionals tend not to have a significant or positive impact. This suggests that more effort needs to be invested to realize all the potential benefits of the PCU's multiprofessional approach to care.

Transforming community health services for children and young people who are ill: a quasi-experimental evaluation

Background

Children’s community nursing (CCN) services support children with acute, chronic, complex and end-of-life care needs in the community.

Objectives

This research examined the impact of introducing and expanding CCN services on quality, acute care and costs.

Methods

A longitudinal, mixed-methods, case study design in three parts. The case studies were in five localities introducing or expanding services. Part 1: an interrupted time series (ITS) analysis of Hospital Episode Statistics on acute hospital admission for common childhood illness, and bed-days and length of stay for all conditions, including a subset for complex conditions. The ITS used between 60 and 84 time points (monthly data) depending on the case site. Part 2: a cost–consequence analysis using activity data from CCN services and resource-use data from a subset of families (n = 32). Part 3: in-depth interviews with 31 parents of children with complex conditions using services in the case sites and a process evaluation of service change with 41 NHS commissioners, managers and practitioners, using longitudinal in-depth interviews, focus groups and documentary data.

Findings

Part 1: the ITS analysis showed a mixed pattern of impact on acute activity, with the greatest reductions in areas that had rates above the national average before CCN services were introduced and significant reductions in some teams in acute activity for children with complex conditions. Some models of CCN appear to have more potential for impact than others. Part 2: the cost–consequence analysis covered only part of the CCN teams’ activity. It showed some potential savings from reduced admissions and bed-days, but none that was greater than the total cost of the services. Part 3: three localities implemented services as planned, one achieved partial service change and one was not able to achieve any service change. Organisational stability, finance, medical stakeholder support, competition, integration with primary care and visibility influenced the planning and implementation of new and expanded CCN services. Feeling supported to manage their ill child at home was a key outcome of using services for parents. Various service features contributed to this and were important in different ways at different times. Other outcomes included being able to avoid hospital care, enabling the child to stay in school, and getting respite. Although parents judged that care was of high quality when teams enabled them to feel supported, reassured and secure in managing their ill child at home, this did not depend on a constant level of contact from teams.

Limitations

Delays in service reconfigurations required adaptation of research activity across sites. Use of administrative data, such as Hospital Episode Statistics, for research purposes is technically difficult and imposed some limitations on both the ITS and the cost–consequence analyses.

Conclusions

Large, generic CCN teams that integrate acute admission avoidance for all children with support for children with complex conditions and highly targeted teams for children with complex conditions offer the possibility of supporting children more appropriately at home while also making some difference to acute activity. This possibility remains to be tested further.

Future work

Further work should refine the evidence on outcomes of services by looking at outcomes in promising models, value for money and measuring quality-based outcomes.

Access to patient-centered medical homes in children with sickle cell disease

To determine the proportion of children with sickle cell disease (SCD) followed in a subspecialty clinic with access to a primary care provider (PCP) exhibiting practice-level qualities of a patient-centered medical home (PCMH). We surveyed 200 parents/guardians of children with SCD using a 44-item tool addressing PCP access, caregiver attitudes toward PCPs, barriers to healthcare utilization, perceived disease severity, and satisfaction with care received in the PCP versus SCD clinic settings. Individual PCMH criteria measured were a personal provider relationship and medical care characterized as accessible, comprehensive and coordinated. Although 94 % of respondents reported a PCP for their child, there was greater variation in the proportion of PCPs who met other individual PCMH criteria. A higher proportion of PCPs met criteria for coordinated care when compared to accessible or comprehensive care. In multivariate models, transportation availability, lower ER visit frequency and greater PCP visit frequency were associated favorably with having a PCP meeting criteria for accessible and coordinated care. Child and respondent demographics and disease severity had no impact on PCMH designation. Average respondent satisfaction scores for the SCD clinic was higher, when compared to satisfaction scores for the PCP. For children with SCD, access to a PCP is not synonymous with access to a medical home. While specific factors associated with PCMH access may be identified in children with SCD, their cause and effect relationships need further study.

Care coordination over time in medical homes for children with special health care needs

OBJECTIVES

To explore how care coordination changes conceptually and practically in primary care practices when implementing the medical home and to identify reasons for different types of changes.

METHODS

Six years after a 2003-2004 national learning collaborative to implement the medical home model for children with special health care needs, we examined care coordination in 12 pediatric practices with the highest postintervention Medical Home Index scores, indicating high level of adoption of the model. Data included interviews of 48 clinicians, care coordinators, and parents and medical record reviews of 60 patients with special health care needs receiving care in these practices.

RESULTS

Initially, care coordination activities were prompted by patients' acute problems, and over time activities, tools, and policies were implemented to avert many such problems and expand the scope of services offered to patients. Example activities were making previsit calls with families, writing care plans, developing relationships with community agencies, and tracking referrals. Although some activities were common across practices, the persons involved and efforts toward different activities varied with practice context. Drivers included motivation and creativity of medical home teams, organizational changes, funding to expand care coordinator positions, protected time for such activities, and adoption of electronic record systems.

CONCLUSIONS

In high-performing medical homes, care coordination activities changed from being mostly reactive to patients' episodic needs to being more systematically proactive and comprehensive. This shift was promoted by factors external and internal to the practice. Ensuring these factors in medical home implementation may accelerate adoption of proactive care coordination activities.

Associations between practice-reported medical homeness and health care utilization among publicly insured children

BACKGROUND

The patient-centered medical home (PCMH) is widely promoted as a model to improve the quality of primary care and lead to more efficient use of health care services. Few studies have examined the relationship between PCMH implementation at the practice level and health care utilization by children. Existing studies show mixed results.

METHODS

Using practice-reported PCMH assessments and Medicaid claims from child-serving practices in 3 states participating in the Children's Health Insurance Program Reauthorization Act of 2009 Quality Demonstration Grant Program, this study estimates the association between medical homeness (tertiles) and receipt of well-child care and nonurgent, preventable, or avoidable emergency department (ED) use. Multilevel logistic regression models are estimated on data from 32 practices in Illinois (IL) completing the National Committee for Quality Assurance's (NCQA) medical home self-assessment and 32 practices in North Carolina (NC) and South Carolina (SC) completing the Medical Home Index (MHI) or Medical Home Index-Revised Short Form (MHI-RSF).

RESULTS

Medical homeness was not associated with receipt of age-appropriate well-child visits in either sample. Associations between nonurgent, preventable, or avoidable ED visits and medical homeness varied. No association was seen among practices in NC and SC that completed the MHI/MHI-RSF. Children in practices in IL with the highest tertile NCQA self-assessment scores were less likely to have a nonurgent, preventable, or avoidable ED visit than children in practices with low (odds ratio 0.65; 95% confidence interval 0.47-0.92; P < .05) and marginally less likely to have such a visit compared with children in practices with medium tertile scores (odds ratio 0.72, 95% confidence interval 0.52-1.01; P = .06).

CONCLUSIONS

Higher levels of medical homeness may be associated with lower nonurgent, preventable, or avoidable ED use by publicly insured children. Robust longitudinal studies using multiple measures of medical homeness are needed to confirm this observation.

Pediatric to adult transition: a quality improvement model for primary care

PURPOSE

To examine the relationship between quality improvement activities with pediatric and adult primary care practices and improvements in transition from pediatric to adult care.

METHODS

This was a time-series comparative study of changes in pediatric and adult practices involving five large pediatric and adult academic health centers in the District of Columbia. Using the Health Care Transition Index (pediatric and adult versions), we examined improvements in specific indicators of transition performance, including development of an office transition policy, provider knowledge and skills related to transition, identification of transitioning youth, transition preparation of youth, transition planning, and transfer of care.

RESULTS

Improvements took place in all six transition quality indicators in the pediatric and adult practices that participated in a 2-year learning collaborative to implement the "Six Core Elements of Health Care Transition," a quality improvement intervention modeled after the American Academy of Pediatrics/American Academy of Family Physicians/American College of Physicians Clinical Report on Transition. All sites established a practice-wide policy on transition and created an organized clinical process for tracking transition preparation. The pediatric sites conducted transition readiness assessments with 88% of eligible youth and prepared transition plans for 29% of this group. The adult sites conducted transition readiness assessments with 73% of eligible young adults and developed plans for 33%. A total of 50 were transferred in a systematic way to adult primary care practices.

CONCLUSIONS

Quality improvement using the Six Core Elements of Health Care Transition resulted in the development of a systematic clinical transition process in pediatric and adult academic primary care practices.

A systematic review of stakeholder engagement in comparative effectiveness and patient-centered outcomes research

OBJECTIVES

We conducted a review of the peer-reviewed literature since 2003 to catalogue reported methods of stakeholder engagement in comparative effectiveness research and patient-centered outcomes research.

METHODS AND RESULTS

We worked with stakeholders before, during and after the review was conducted to: define the primary and key research questions; conduct the literature search; screen titles, abstracts and articles; abstract data from the articles; and analyze the data. The literature search yielded 2,062 abstracts. The review was conducted on 70 articles that reported on stakeholder engagement in individual research projects or programs.

FINDINGS

Reports of stakeholder engagement are highly variable in content and quality. We found frequent engagement with patients, modestly frequent engagement with clinicians, and infrequent engagement with stakeholders in other key decision-making groups across the healthcare system. Stakeholder engagement was more common in earlier (prioritization) than in later (implementation and dissemination) stages of research. The roles and activities of stakeholders were highly variable across research and program reports.

RECOMMENDATIONS

To improve on the quality and content of reporting, we developed a 7-Item Stakeholder Engagement Reporting Questionnaire. We recommend three directions for future research: 1) descriptive research on stakeholder-engagement in research; 2) evaluative research on the impact of stakeholder engagement on the relevance, transparency and adoption of research; and 3) development and validation of tools that can be used to support stakeholder engagement in future work.

Association between medical home characteristics and staff professional experiences in pediatric practices

BACKGROUND

The patient-centered medical home (PCMH) model has been touted as a potential way to improve primary care. As more PCMH projects are undertaken it is critical to understand professional experiences as staff are key in implementing and maintaining the necessary changes. A paucity of information on staff experiences is available, and our study aims to fill that critical gap in the literature.

METHODS

Eligible pediatric practices were invited to participate in the Florida Pediatric Medical Home Demonstration Project out which 20 practices were selected. Eligibility criteria included a minimum of 100 children with special health care needs and participation in Medicaid, a Medicaid health plan, or Florida KidCare. Survey data were collected from staff working in these 20 pediatric practices across Florida. Ware's seven-point scale assessed satisfaction and burnout was measured using the six-point Maslach scale. The Medical Home Index measured the practice's medical home characteristics. Descriptive and multivariate analyses were conducted. In total, 170 staff members completed the survey and the response rate was 42.6%.

RESULTS

Staff members reported high job satisfaction (mean 5.54; SD 1.26) and average burnout. Multivariate analyses suggest that care coordination is positively associated (b = 0.75) and community outreach is negatively associated (b = -0.18) with job satisfaction. Quality improvement and organizational capacity are positively associated with increased staff burnout (OR = 1.37, 5.89, respectively). Chronic condition and data management are associated with lower burnout (OR = 0.05 and 0.20, respectively). Across all models adaptive reserve, or the ability to make and sustain change, is associated with higher job satisfaction and lower staff burnout.

CONCLUSIONS

Staff experiences in the transition to becoming a PCMH are important. Although our study is cross-sectional, it provides some insight about how medical home, staff and practice characteristics are associated with job satisfaction and burnout. Many PCMH initiatives include facilitation and it should assist staff on how to adapt to change. Unless staff needs are addressed a PCMH may be threatened by fatigue, burnout, and low morale.

What is care coordination?

Introduction

Care coordination is a high-priority area for improvement across healthcare systems, but no consensus definition of care coordination exists.

Methods

This article reviews published definitions of the term “care coordination,” identifies common themes among them, and presents a broad working definition of care coordination.

Results

The review identified 57 unique definitions of care coordination, ranging widely in the scope of participants, settings, and care processes included. Five major themes emerged from the definitions: care coordination involves numerous participants, is necessitated by interdependence among participants and activities, requires knowledge of others’ roles and resources, relies on information exchange, and aims to facilitate appropriate healthcare delivery. Only one definition identified included all five themes, and no one theme was found in a clear majority of definitions. The synthesized themes were incorporated into a broad working definition of care coordination, which has resulted in numerous uses (e.g. guide for systematic review of interventions, development of a measures repository, reference for this journal’s recast focus on the subject).

Discussion

Some ambiguity remains about the definition of care coordination, but the breadth of definitions in use underscores its widespread recognition as important for high-quality care. Even as understanding of care coordination continues to evolve, broad and flexible definitions can help guide the iterative process of developing conceptual models, testing them empirically, refining models, generating evidence about what works best, and ultimately improving the quality of care.

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.

How do rural patients benefit from the patient-centred medical home? A card study in the High Plains Research Network

Context The patient-centred medical home (PCMH) has become a dominant model for improving the quality and cost of primary care. Geographic isolation, small populations, privacy concerns and staffing requirements may limit implementation of the PCMH in clinical practice. Objective To determine the primary care provider perceived benefit of PCMH for patients in rural Colorado. Design, setting and participants The High Plains Research Network (HPRN) is a community and practice-based research network spanning 30 000 square miles in 16 counties in eastern Colorado. The HPRN consists of 58 practices, 120 primary care clinicians and 145 000 residents. Main outcome measures Providers' perceived benefit of PCMH for individual patients. Results Seventy-eight providers in 37 practices saw 1093 patients and completed 1016 surveys. There was wide variation among the provider-perceived benefits of PCMH elements ranging from 9% for group visits to 64% for electronic prescribing. Provider-perceived benefit was higher for patients with a chronic medical condition. Conclusions Rural primary care providers perceived patient benefit for numerous elements of the PCMH. There is need to consider what PCMH elements may be required in practice and what components might be optional. Our findings reveal that rural practices share PCMH aspirations including commitment to quality, safety, outcomes, cost reduction, and patient and provider satisfaction. These findings support the need for ongoing conversation about how to best provide a locally relevant medical home.

Measuring primary care organizational capacity for diabetes care coordination: the Diabetes Care Coordination Readiness Assessment

BACKGROUND

Not all primary care clinics are prepared to implement care coordination services for chronic conditions, such as diabetes. Understanding true capacity to coordinate care is an important first-step toward establishing effective and efficient care coordination. Yet, we could identify no diabetes-specific instruments to systematically assess readiness and/or status of primary care clinics to engage in diabetes care coordination.

OBJECTIVE

This report describes the development and initial validation of the Diabetes Care Coordination Readiness Assessment (DCCRA), which is intended to measure primary care clinic readiness to coordinate care for adult patients with diabetes.

DESIGN

The instrument was developed through iterative item generation within a framework of five domains of care coordination: Organizational Capacity, Care Coordination, Clinical Management, Quality Improvement, and Technical Infrastructure.

PARTICIPANTS

Validation data was collected on 39 primary care clinics.

MAIN MEASURES

Content validity, inter-rater reliability, internal consistency, and construct validity of the 49-item instrument were assessed.

KEY RESULTS

Inter-rater agreement indices per item ranged from 0.50 to 1.0. Cronbach's alpha of the entire instrument was 0.964, and for the five domain scales ranged from 0.688 to 0.961. Clinics with existing care coordinators were rated as more ready to support care coordination than clinics without care coordinators for the entire DCCRA and for each domain, supporting construct validity.

CONCLUSIONS

As providers increasingly attempt to adopt patient-centered approaches, introduction of the DCCRA is timely and appropriate for assisting clinics with identifying gaps in provision of care coordination services. The DCCRA's strengths include promising psychometric properties. A valid measure of diabetes care coordination readiness should be useful in diabetes program evaluation, assistance with quality improvement initiatives, and measurement of patient-centered care in research.

Metrics for assessing improvements in primary health care

Metrics focus attention on what is important. Balanced metrics of primary health care inform purpose and aspiration as well as performance. Purpose in primary health care is about improving the health of people and populations in their community contexts. It is informed by metrics that include long-term, meaning- and relationship-focused perspectives. Aspirational uses of metrics inspire evolving insights and iterative improvement, using a collaborative, developmental perspective. Performance metrics assess the complex interactions among primary care tenets of accessibility, a whole-person focus, integration and coordination of care, and ongoing relationships with individuals, families, and communities; primary health care principles of inclusion and equity, a focus on people's needs, multilevel integration of health, collaborative policy dialogue, and stakeholder participation; basic and goal-directed health care, prioritization, development, and multilevel health outcomes. Environments that support reflection, development, and collaborative action are necessary for metrics to advance health and minimize unintended consequences.

Medical home characteristics and asthma control: a prospective, observational cohort study protocol

Background:

This paper describes the methods for an observational comparative effectiveness research study designed to test the association between practice-level medical home characteristics and asthma control in children and adults receiving care in safety-net primary care practices.

Methods:

This is a prospective, longitudinal cohort study, utilizing survey methodologies and secondary analysis of existing structured clinical, administrative, and claims data. The Scalable Architecture for Federated Translational Inquiries Network (SAFTINet) is a safety net-oriented, primary care practice-based research network, with federated databases containing electronic health record (EHR) and Medicaid claims data. Data from approximately 20,000 patients from 50 practices in four healthcare organizations will be included. Practice-level medical home characteristics will be correlated with patient-level asthma outcomes, controlling for potential confounding variables, using a clustered design. Linear and non-linear mixed models will be used for analysis. Study inception was July 1, 2012. A causal graph theory approach was used to guide covariate selection to control for bias and confounding.

Discussion:

Strengths of this design include a priori specification of hypotheses and methods, a large sample of patients with asthma cared for in safety-net practices, the study of real-world variations in the implementation of the medical home concept, and the innovative use of a combination of claims data, patient-reported data, clinical data from EHRs, and practice-level surveys. We address limitations in causal inference using theory, design and analysis.

Assessing progress toward becoming a patient-centered medical home: an assessment tool for practice transformation

Objective. To describe the properties of the Patient-Centered Medical Home Assessment (PCMH-A) as a tool to stimulate and monitor progress among primary care practices interested in transforming to patient-centered medical homes (PCMHs).

Study Setting. Sixty-five safety net practices from five states participating in a national demonstration program for PCMH transformation.

Study Design. Longitudinal analyses of PCMH-A scores were performed. Scores were reviewed for agreement and sites were categorized over time into one of five categories by external facilitators. Comparisons to key activity completion rates and NCQA PCMH recognition status were completed.

Data Collection/Extraction Methods. Multidisciplinary teams at each practice completed the 33-item self-assessment tool every 6 months between March 2010 and September 2012.

Principal Findings. Mean overall PCMH-A scores increased (7.2, March 2010, to 9.1, September 2012; [p < .01]). Increases were statistically significant for each of the change concepts (p < .05). Facilitators agreed with scores 82% of the time. NCQA-recognized sites had higher PCMH-A scores than sites that were not yet recognized. Sites that completed more transformation activities and progressed over defined tiers reported higher PCMH-A scores. Scores improved most in areas where technical assistance was provided.

Conclusions. The PCMH-A was sensitive to change over time and provided an accurate reflection of practice transformation.

Medical home transformation in pediatric primary care--what drives change?

PURPOSE

The aim of this study was to characterize essential factors to the medical home transformation of high-performing pediatric primary care practices 6 to 7 years after their participation in a national medical home learning collaborative.

METHODS

We evaluated the 12 primary care practice teams having the highest Medical Home Index (MHI) scores after participation in a national medical home learning collaborative with current MHI scores, a clinician staff questionnaire (assessing adaptive reserve), and semistructured interviews. We reviewed factors that emerged from interviews and analyzed domains and subdomains for their agreement with MHI and adaptive reserve domains and subthemes using a process of triangulation.

RESULTS

At 6 to 7 years after learning collaborative participation, 4 essential medical home attributes emerged as drivers of transformation: (1) a culture of quality improvement, (2) family-centered care with parents as improvement partners, (3) team-based care, and (4) care coordination. These high-performing practices developed comprehensive, family-centered, planned care processes including flexible access options, population approaches, and shared care plans. Eleven practices evolved to employ care coordinators. Family satisfaction appeared to stem from better access, care, and safety, and having a strong relationship with their health care team. Physician and staff satisfaction was high even while leadership activities strained personal time.

CONCLUSIONS

Participation in a medical home learning collaborative stimulated, but did not complete, medical home changes in 12 pediatric practices. Medical home transformation required continuous development, ongoing quality improvement, family partnership skills, an attitude of teamwork, and strong care coordination functions.

The health care home model: primary health care meeting public health goals

In November 2010, the American Public Health Association endorsed the health care home model as an important way that primary care may contribute to meeting the public health goals of increasing access to care, reducing health disparities, and better integrating health care with public health systems. Here we summarize the elements of the health care home (also called the medical home) model, evidence for its clinical and public health efficacy, and its place within the context of health care reform legislation. The model also has limitations, especially with regard to its degree of involvement with the communities in which care is delivered. Several actions could be undertaken to further develop, implement, and sustain the health care home.

Family-centered care: current applications and future directions in pediatric health care

Family-centered care (FCC) is a partnership approach to health care decision-making between the family and health care provider. FCC is considered the standard of pediatric health care by many clinical practices, hospitals, and health care groups. Despite widespread endorsement, FCC continues to be insufficiently implemented into clinical practice. In this paper we enumerate the core principles of FCC in pediatric health care, describe recent advances applying FCC principles to clinical practice, and propose an agenda for practitioners, hospitals, and health care groups to translate FCC into improved health outcomes, health care delivery, and health care system transformation.

Care coordination in a medical home in post-Katrina New Orleans: lessons learned

This is a prospective study to evaluate ability of a nurse care coordinator to: (1) improve ability of a pediatric clinic to meet medical home (MH) objectives and (2) improve receipt of services for families of children with special health care needs (CSHCN). A nurse was hired to provide care coordination for CSHCN in an urban, largely Medicaid pediatric academic practice. CSHCN were identified using a CSHCN Screener. Ability to meet MH criteria was determined using the MH Index (MHI). Receipt of MH services was measured using the MH Family Index (MHFI). After baseline surveys were completed, Hurricane Katrina destroyed the clinic. Care coordination was implemented for the post-disaster population. Surveys were repeated in the rebuilt clinic after at least 3 months of care coordination. The distribution of demographics, diagnoses and percent CSHCN did not significantly change pre and post Katrina. Psychosocial needs such as food, housing, mental health and education were markedly increased. Essential strategies included developing a new tool for determining complexity of needs and involvement of the entire practice in care coordination activities. MHFI showed improvement in receipt of services post care coordination and post-Katrina with P < 0.05 for 13 of 16 questions. MHI demonstrated improvement in care coordination and community outreach domains. Average cost was $36.88 per CSHCN per year. There was significant improvement in the ability of the clinic to meet care coordination and community outreach MH criteria and in family receipt of services after care coordination, despite great increase in psychosocial needs. This study provides practical strategies for implementing care coordination for families of high risk CSHCN in underserved populations.

Supporting the health care transition from adolescence to adulthood in the medical home

Optimal health care is achieved when each person, at every age, receives medically and developmentally appropriate care. The goal of a planned health care transition is to maximize lifelong functioning and well-being for all youth, including those who have special health care needs and those who do not. This process includes ensuring that high-quality, developmentally appropriate health care services are available in an uninterrupted manner as the person moves from adolescence to adulthood. A well-timed transition from child- to adult-oriented health care is specific to each person and ideally occurs between the ages of 18 and 21 years. Coordination of patient, family, and provider responsibilities enables youth to optimize their ability to assume adult roles and activities. This clinical report represents expert opinion and consensus on the practice-based implementation of transition for all youth beginning in early adolescence. It provides a structure for training and continuing education to further understanding of the nature of adolescent transition and how best to support it. Primary care physicians, nurse practitioners, and physician assistants, as well as medical subspecialists, are encouraged to adopt these materials and make this process specific to their settings and populations.

Review of quality measures of the most integrated health care settings for children and the need for improved measures: recommendations for initial core measurement set for CHIPRA

OBJECTIVE

To identify, assess, and make recommendations for inclusion of measures that assess the domain of "most integrated health care setting," with a specific focus on measures of the medical home, one particular mechanism for integrating care, to identify gaps in measurement; and to make recommendations for new measure development.

METHODS

We developed a conceptual framework for care integration and reviewed literature on measures assessing the presence and quality of the medical home to determine their validity, reliability, and feasibility as a proxy for care integration.

RESULTS

We identified 2 broad approaches to assessing the extent to which patients receive care that fulfills the aims of the medical home: 1) organizational assessment of practice systems and processes thought associated with achieving these desired aims (viz, the National Committee for Quality Assurance Physician Practice Connections-Patient Centered Medical Home measure and the Medical Home Index, and 2) direct assessment by patients/families of their experience of care in targeted dimensions. Based on concerns about the absence of reliability data and the feasibility of applying the practice audit/self-assessment approach on a population level for the purpose of state reporting, as well as the limited data linking performance on the specific measures with important child outcomes, we did not recommend any of the measures of organizational assessments of practice systems for inclusion in the core set as an indicator of care integration. In contrast, measures of the medical home based on items from the National Survey of Child Health on a population level of or the Consumer Assessment of Healthcare Providers and Systems for practice- and state-level assessment are more feasible, have known reliability and performance characteristics, and more closely reflect the aims of the medical home, including care integration.

CONCLUSIONS

Measures of health care integration as captured by the experience of care in a medical home can best be assessed for state-level performance through patient/family experience surveys. Better measures of care integration, care coordination, and integration of mental, developmental, and physical health into a comprehensive care system are high-priority topics for measure development.

Defining and measuring the patient-centered medical home

The patient-centered medical home (PCMH) is four things: 1) the fundamental tenets of primary care: first contact access, comprehensiveness, integration/coordination, and relationships involving sustained partnership; 2) new ways of organizing practice; 3) development of practices' internal capabilities, and 4) related health care system and reimbursement changes. All of these are focused on improving the health of whole people, families, communities and populations, and on increasing the value of healthcare. The value of the fundamental tenets of primary care is well established. This value includes higher health care quality, better whole-person and population health, lower cost and reduced inequalities compared to healthcare systems not based on primary care. The needed practice organizational and health care system change aspects of the PCMH are still evolving in highly related ways. The PCMH will continue to evolve as evidence comes in from hundreds of demonstrations and experiments ongoing around the country, and as the local and larger healthcare systems change. Measuring the PCMH involves the following: Giving primacy to the core tenets of primary care. Assessing practice and system changes that are hypothesized to provide added value Assessing development of practices' core processes and adaptive reserve. Assessing integration with more functional healthcare system and community resources. Evaluating the potential for unintended negative consequences from valuing the more easily measured instrumental features of the PCMH over the fundamental relationship and whole system aspects. Recognizing that since a fundamental benefit of primary care is its adaptability to diverse people, populations and systems, functional PCMHs will look different in different settings. Efforts to transform practice to patient-centered medical homes must recognize, assess and value the fundamental features of primary care that provide personalized, equitable health care and foster individual and population health.

Medical homes: "where you stand on definitions depends on where you sit"

The medical home is a potentially transformative strategy to address issues of access, quality, and efficiency in the delivery of health care in the United States. While numerous organizations support a physician-driven definition, it is by no means the universally accepted definition. Several professional groups, payers, and researchers have offered differing, or nuanced, definitions of medical homes. This lack of consensus has contributed to uncertainty among providers about the medical home. We conducted a systematic review of the literature on the medical home and identified 29 professional, government, and academic sources offering definitions. While consensus appears to exist around a core of selected features, the medical home means different things to different people. The variation in definitions can be partly explained by the obligation of organizations to their members and whether the focus is on the patient or provider. Differences in definitions have implications at both the policy and practice levels.

Latino access to the patient-centered medical home

BACKGROUND

Disparities can be caused by minorities receiving care in low-quality settings. The patient-centered medical home (PCMH) has been identified as a model of high-quality primary care that can eliminate disparities. However, Latinos are less likely to have PCMHs.

OBJECTIVE

To identify Latino subgroup variations in having a PCMH, its impact on disparities, and to identify factors associated with Latinos having a PCMH.

DESIGN

Analysis of the 2005 MEPS Household Component, a nationally representative survey with an oversample of Latino adults. The total sample was 24,000 adults, including 6,200 Latinos.

MEASUREMENTS

The PCMH was defined as having a regular provider, who provides total care, fosters patient engagement in care, and offers easy access to care. Self reports of preventive care (cholesterol screening, blood pressure check, mammography, and prostate-specific antigen screening) and patient experiences were examined.

RESULTS

White (57.1%) and Puerto Rican (59.3%) adults were most likely to have a PCMH, while Mexican/Mexican Americans (35.4%) and Central and South Americans (34.2%) were least likely. Much of the disparity was caused by lack of access to a regular provider. Respondents with a PCMH had higher rates of preventive care and positive patient experiences. Disparities in care were eliminated or reduced for Latinos with PCMHs. The regression models showed private insurance, which is less common among all Latinos, was an important predictor of having a PCMH.

CONCLUSIONS

Eliminating health-care disparities will require assuring access to the PCMH. Addressing differences in health-care coverage that contribute to lower rates of Latino access to the PCMH will also reduce disparities.

Health literacy and child health promotion: implications for research, clinical care, and public policy

The nation's leading sources of morbidity and health disparities (eg, preterm birth, obesity, chronic lung disease, cardiovascular disease, type 2 diabetes, mental health disorders, and cancer) require an evidence-based approach to the delivery of effective preventive care across the life course (eg, prenatal care, primary preventive care, immunizations, physical activity, nutrition, smoking cessation, and early diagnostic screening). Health literacy may be a critical and modifiable factor for improving preventive care and reducing health disparities. Recent studies among adults have established an independent association between lower health literacy and poorer understanding of preventive care information and poor access to preventive care services. Children of parents with higher literacy skills are more likely to have better outcomes in child health promotion and disease prevention. Adult studies in disease prevention have suggested that addressing health literacy would be an efficacious strategy for reducing health disparities. Future initiatives to reduce child health inequities should include health-promotion strategies that meet the health literacy needs of children, adolescents, and their caregivers.

Improvement in the family-centered medical home enhances outcomes for children and youth with special healthcare needs

Family-centered, coordinated, comprehensive, and culturally competent care for children and youth with special healthcare needs is a national priority. Access to a primary care medical home is a US Maternal and Child Health Bureau performance measure. Most primary care practices lack methods by which to partner with families and improve care. Gaps remain in the number of children with access to a high-quality medical home. The Medical Home Index and Medical Home Family Index and Survey resulting from 10 pilot practices reveal improvements in practice capacity and subsequently in child and family outcomes.

The medical home--improving quality of primary care for children

The concept of a medical home appears to be a key driver for enhancing the value of health services as care systems are transitioned to meet the ongoing challenges of improving quality and containing costs. This article provides an overview of the challenges faced in United States health care delivery systems that affect child health, explains how the medical home might address them, describes methods for measuring quality in medical homes, and identifies barriers to implementation of the model.

Improved outcomes associated with medical home implementation in pediatric primary care

OBJECTIVE

The medical home model with its emphasis on planned care, care coordination, family-centered approaches, and quality provides an attractive concept construct for primary care redesign. Studies of medical home components have shown increased quality and reduced costs, but the medical home model as a whole has not been studied systematically. This study tested the hypothesis that increased medical homeness in primary care practice is associated with decreased utilization of health services and increased patient satisfaction.

METHODS

Forty-three primary care practices were identified through 7 health plans in 5 states. Using the Medical Home Index (MHI), each practice's implementation of medical home concepts "medical homeness" was measured. Health plans provided the previous year's utilization data for children with 6 chronic conditions. The plans identified 42 children in each practice with these chronic conditions and surveyed their families regarding satisfaction with care and burden of illness.

RESULTS

Higher MHI scores and higher subdomain scores for organizational capacity, care coordination, and chronic-condition management were associated with significantly fewer hospitalizations. Higher chronic-condition management scores were associated with lower emergency department use. Family survey data yielded no recognizable trends with respect to the medical home measurement.

CONCLUSIONS

Developing an evidence base for the value of the primary care medical home has importance for providers, payers, policy makers, and consumers. Reducing hospitalizations through enhanced primary care provides a potential case for new reimbursement strategies supporting medical home services such as care coordination. Larger-scale studies are needed to further develop/examine these relationships.

A longitudinal study of a pediatric practice-based versus an agency-based model of care coordination for children and youth with special health care needs

BACKGROUND

Care coordination has been shown to improve the quality of care for children and youth with special health care needs (CYSHCN). However, there are different models for structuring care coordination in relation to the medical home and most Title V agencies use an agency-based model of care coordination. No studies have prospectively compared a practice-based care coordination model to a Title V agency-based care coordination model.

OBJECTIVE

Report the results of a prospective cohort study comparing a practice-based nurse care coordinator model with Title V agency-based care coordination model.

DESIGN/METHODS

Three pediatric practices received the intervention, placement of a nurse care coordinator onsite within the practice, along with training and quality improvement on the principles of the medical home. Three practices continued to rely on agency-based care coordination services. CYSHCN in the practices were identified, interviewed at baseline, and re-interviewed after 18 months. We interviewed 262 families/children at baseline and 144 families/children (76 in the intervention and 68 in the comparison group) at 18 months. Families rated the quality of services they received from the care coordinator and the pediatric practice, and their experience of barriers to services for their CYSHCN.

RESULTS

Families in the practice-based care coordination group were more likely to report improvement in their experience with the care coordinator (P = 0.02), fewer barriers to needed services (P = 0.003), higher overall satisfaction with care coordination (P = 0.03), and better treatment by office staff (P = 0.04).

CONCLUSIONS

We found that for families of CYSHCN, practice-based care coordination in the medical home led to increased satisfaction with the quality of care they received and a reduction of barriers to care. The practice-based care coordination model is utilized by a minority of State Title V agencies and should be considered as a potentially more effective model than the agency-based approach.
