Effectiveness of diabetes interventions in the patient-centered medical home

Patient-centered medical home pharmacists' impact on composite quality care measures for patients with uncontrolled type 2 diabetes

BACKGROUND

Patients with uncontrolled diabetes are at risk for developing complications. Many health care systems have implemented multidisciplinary care models including pharmacists to help achieve quality care measures to reduce complications.

OBJECTIVE

This study aimed to evaluate whether patients with uncontrolled type 2 diabetes mellitus (T2D) seen at patient-centered medical home (PCMH) clinics affiliated with an academic medical center are more likely to meet a composite of diabetes quality care measures with a pharmacist on their care team than usual care patients without a pharmacist on their care team.

METHODS

This is a cross-sectional study. The setting included PCMH primary care clinics affiliated with an academic medical center from January 2017 to December 2020. Included were adults aged 18 to 75 years with a diagnosis of T2D, hemoglobin A1C (A1C) more than 9%, and established with a PCMH provider. The intervention is inclusion of PCMH pharmacist on the patient's care team for management of T2D per a collaborative practice agreement. The main outcome measures included A1C ≤9% per last recorded value during observation period, a composite A1C ≤9% and completion of yearly laboratory tests, and a composite A1C ≤9%, completion of yearly laboratory tests, and statin prescription for adults aged 40-75 years.

RESULTS

Identified were 1807 patients in the usual care cohort with mean baseline A1C of 10.7% and 207 patients in the pharmacist cohort with mean baseline A1C of 11.1%. The pharmacist cohort was more likely to have an A1C of ≤9% at the end of the observation period (70.1% vs. 45.4%; P < 0.001), a composite of measures met (28.5% vs. 16.8%; P < 0.001), and a composite of measures met for patients aged 40-75 years (27.2% vs. 13.7%; P < 0.001).

CONCLUSION

Pharmacist involvement in the multidisciplinary management of uncontrolled T2D is associated with a higher attainment of a composite of quality care measures at the population health level.

Cost analysis of a Patient-Centred Medical Home for community-dwelling older adults with complex needs in Singapore

INTRODUCTION

The Patient-Centred Medical Home (PCMH) demonstration in Singapore, launched in November 2016, aimed to deliver integrated and patient-centred care for patients with biopsychosocial needs. Implementation was based on principles of comprehensiveness, coordinated care and shared decision-making.

METHOD

We conducted a prospective single-arm pre-post study design, which aimed to perform cost analysis of PCMH from the perspectives of patients, healthcare providers and society. We assessed short-to-intermediate-term health-related costs by analysing data on resource use and unit costs of resources.

RESULTS

We analysed 165 participants enrolled in PCMH from November 2017 to April 2020, with mean age of 77 years. Compared to the 3-month period before enrolment, mean total direct and indirect participant costs and total health system costs increased, but these were not statistically significant. There was a significant decrease in mean cost for primary care (government primary care and private general practice) in the first 3-month and second 3-month periods after enrolment, accompanied by a significant decrease in service utilisation and mean costs for PCMH services in the second 3-month period post-enrolment. This suggested a shift in resource costs from primary care to community-based care provided by PCMH, which had added benefits of both clinic-based primary care and home-based care management. Findings were consistent with a lower longer-term cost trajectory for PCMH after the initial onboarding period. Indirect caregiving costs remained stable.

CONCLUSION

The PCMH care model was associated with reduced costs to the health system and patients for usual primary care, and did not significantly change societal costs.

Influence of interaction between community health workers and adults with chronic diseases on risk mitigation through care coordination

Introduction

Addressing health disparities and barriers to care requires a comprehensive approach that involves participation of health care providers, multiple organizations, and service providers in the communities affected. Given the importance of using community health workers to help address the complex and overlapping medical, social, and behavioral needs of high-risk individuals, it is of utmost importance to understand their impact on health outcomes. This study examines how in-person interaction between community health workers and their clients influence the client's level of risk mitigation achieved through care coordination using the Pathways Community HUB model.

Methods

The study utilized two years of data extracted from the Care Coordination Systems database for 391 adults who participated in the Northwest Ohio Pathways Community HUB program. Using multinomial logistic regression analysis, we assessed how the interaction between community health workers and adults with chronic diseases who participated in the Northwest Ohio Pathways Community HUB program influenced the successful mitigation of their social, behavioral, and other medical risks over a 2-year period.

Results

Our findings show that as the number of in-person contacts between the community health worker and the client increased, the likelihood of completing all Pathways increased by 27% when compared to completing less than 50% of the assigned Pathways, after adjusting for potential confounders (odds ratio: 1.27, 95% confidence interval: 1.07−1.52).

Discussion

Using community health workers as part of care coordination teams may be effective in connecting communities to systems of care, helping individuals manage their health conditions and connecting individuals to needed social services. Their direct in-person interaction with at-risk individuals may increase the extent to which these individuals successfully address risks to their health and well-being.

Cost-Effectiveness of Technology-Assisted Case Management in Low-Income, Rural Adults with Type 2 Diabetes

Objective: The objective of this study was to examine whether delivering technology-assisted case management (TACM) with medication titration by nurses under physician supervision is cost effective compared with usual care (standard office procedures) in low-income rural adults with type 2 diabetes.

Methods: One hundred and thirteen low-income, rural adults with type 2 diabetes and hemoglobin A1c (HbA1c) ≥8%, were randomized to a TACM intervention or usual care. Effectiveness was measured as differences in HbA1c between the TACM and usual care groups at 6 months. Total cost per patient included intervention or usual care cost, medical care cost, and income loss associated with lost workdays. The total cost per patient and HbA1c were used to estimate a joint distribution of incremental cost and incremental effect of TACM compared with usual care. Incremental cost-effectiveness ratios (ICERs) were estimated to summarize the cost-effectiveness of the TACM intervention relative to usual care to decrease HbA1c by 1%.

Results: Costs due to intervention, primary care, other health care, emergency room visits, and workdays missed showed statistically significant differences between the groups (usual care $1,360.49 vs. TACM $5,379.60, p=0.004), with an absolute cost difference of $4,019.11. Based on the intervention cost per patient and the change in HbA1c, the median bootstrapped ICERs was estimated to be $6,299.04 (standard error=731.71) per 1% decrease in HbA1c.

Conclusion: Based on these results, a 1% decrease in HbA1c can be obtained with the TACM intervention at an approximate cost of $6,300; therefore, it is a cost-effective option for treating vulnerable populations of adults with type 2 diabetes.

Cost-effectiveness of Telephone-Delivered Education and Behavioral Skills Intervention for African American Adults with Diabetes

Purpose

Evaluate cost-effectiveness of a telephone-delivered education and behavioral skills intervention in reducing glycemic control (HbA1c) and decreasing risk of complications.

Methods

Data from a randomized controlled trial, conducted from August 1, 2008 - June 30, 2010 and using a 2x2 factorial design delivered to 255 African American adults not meeting glycemic targets for diabetes were used. Though the primary aim found no significant differences in HbA1c between groups, there was an overall drop in HbA1c across arms and differential cost. Primary clinical outcome was HbA1c measured at 12-months. Costs were estimated based on self-reported utilization of primary care, emergency, and other health care. Costs due to lost wages were calculated based on self-reported days of work missed due to illness. The Michigan Model for Diabetes was used to estimate 10-year probability of developing congestive heart failure, cardiovascular disease, end stage renal disease, stroke, myocardial infarction, all cause death, and CVD death. Total cost per patient and clinical outcomes were used to estimate an incremental cost effectiveness ratio (ICER) using non-parametric bootstrapping.

Results

ICERs indicated combined education and skills intervention was $3,630 less expensive than usual care to achieve a 0.6% decrease in HbA1c and was between $34,000 and $95,000 less expensive than usual care to reduce risk of complications. The knowledge only intervention was $661 less expensive than usual care and the behavioral skills only intervention did not indicate cost effectiveness.

Conclusion

The combined intervention ICER for HbA1c is comparable to other education programs and the ICER to reduce the probability of complications falls below previously recommended long-term cut-off of $100,000, suggesting cost-effectiveness in an African American population.

Quality of rheumatology care for patients with fibromyalgia and chronic pain syndromes

Background

One-third of primary care providers (PCPs) refer patients with fibromyalgia or chronic pain (FM/CP) to specialist care, typically rheumatology. Yet, comprehensive data on the quality of rheumatology care for patients with FM/CP are currently lacking.

Methods

Records of patients referred for rheumatology consultation for FM/CP and seen at a single academic centre between 2017 and 2018 were extracted by retrospective chart review. Variables were diagnostic accuracy (at referral vs consultation), resource utilisation (investigations, medications, medical and allied health referral), direct costs (physician billing, staff salary, investigation fees) and access (consult wait time). Patient experience and referring PCP experience surveys were administered.

Results

79 charts were identified. Following consultation, 81% of patients (n=64) maintained the same diagnosis of FM/CP, 19% (n=15) were diagnosed with regional pain and 0% of patients (n=0) were diagnosed with an inflammatory arthritis or connective tissue disease. Investigations were ordered for 37% of patients (n=29), medication prescribed for 10% (n=8) and an allied health referral provided for 54% (n=43). Direct costs totalled $19 745 (average $250/consult; range $157–$968/consult). Consultation wait time averaged 184 days (range 62–228 days). Out of the seven (64%) responses to the patient experience survey, 86% of patients (n=6) were satisfied with provider communication but the consultation ‘definitely’ met the expectations of only 57% (n=4). The PCP survey returned an insufficient response rate.

Conclusions

This study found that no patient referred to rheumatology care for FM/CP was diagnosed with an inflammatory arthritis or connective tissue disease. Furthermore, patients with FM/CP experience lengthy wait times for rheumatology care which delay their management of chronic pain. Interdisciplinary and collaborative healthcare models can potentially provide higher quality care for patients with FM/CP.

The Patient-centered Medical Home as an Intervention Strategy for Diabetes Mellitus: A Systematic Review of the Literature

BACKGROUND

Poorly managed diabetes mellitus increases health care expenditures and negatively impacts health outcomes. There are 34 million people living with diabetes in the United States with a direct annual medical cost of $237 billion. The patient-centered medical home (PCMH) was introduced to transform primary care by offering team-based care that is accessible, coordinated, and comprehensive. Although the PCMH is believed to address multiple gaps in delivering care to people living with chronic diseases, the research has not yet reported clear benefits for managing diabetes.

OBJECTIVE

The study reviews the scientific literature about diabetes mellitus outcomes reported by PCMHs, and understands the impact of team-based care, interdisciplinary communication, and care coordination strategies on the clinical, financial, and health-related outcomes.

METHODS

The systematic review was performed according to the Cochrane method and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Eight databases were systematically searched for articles. The Oxford Centre for Evidence-based Medicine Levels of evidence and the Critical Appraisal Skills Programme systematic review checklist were used to evaluate the studies.

RESULTS

The search resulted in 596 articles, of which 24 met all the inclusion criteria. Care management resulted in more screenings and better preventive care. Pharmacy-led interventions and technology were associated with positive clinical outcomes, decreased utilization, and cost savings. Most studies reported decreased emergency room visits and less inpatient admissions.

CONCLUSION

The quality and strength of the outcomes were largely inconclusive about the overall effectiveness of the PCMH. Defining and comparing concepts across studies was difficult as universal definitions specific to the PCMH were not often applied. More research is needed to unpack the care model of the PCMH to further understand how the individual key components, such as care bundles, contribute to improved outcomes. Further evaluations are needed for team-based care, communication, and care coordination with comparisons to patient, clinical, health, and financial outcomes.

Processes and outcomes of diabetes mellitus care by different types of team primary care models

Background

Team care improves processes and outcomes of care, especially for patients with complex medical conditions that require coordination of care. This study aimed to compare the processes and outcomes of care provided to older patients with diabetes by primary care teams comprised of only primary care physicians (PCPs) versus team care that included nurse practitioners (NPs) or physician assistants (PAs).

Methods

We studied 3,524 primary care practices identified via social network analysis and 306,741 patients ≥66 years old diagnosed with diabetes in or before 2015 in Medicare data. Guideline-recommended diabetes care included eye examination, hemoglobin A1c test, and nephropathy monitoring. High-risk medications were based on recommendations from the American Geriatrics Society Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. Preventable hospitalizations were defined as hospitalizations for a potentially preventable condition.

Results

Compared with patients in the PCP only teams, patients in the team care practices with NPs or PAs received more guideline-recommended diabetes care (annual eye exam: adjusted odds ratio (aOR): 1.04 (95% CI: 1.00–1.08), 1.08 (95% CI: 1.03–1.13), and 1.10 (95% CI: 1.05–1.15), and HbA1C test: aOR: 1.11 (95% CI: 1.04–1.18), 1.11 (95% CI: 1.02–1.20), and 1.15 (95% CI: 1.06–1.25) for PCP/NP, PCP/NP/PA, and PCP/PA teams). Patients in the PCP/NP and the PCP/PA teams had a slightly higher likelihood of being prescribed high-risk medications (aOR: 1.03 (95% CI: 1.00–1.07), and 1.06 (95% CI: 1.02–1.11), respectively). The likelihood of preventable hospitalizations was similar among patients cared for by various types of practices.

Conclusion

The team care practices with NPs or PAs were associated with better adherence to clinical practice guideline recommendations for diabetes compared to PCP only practices. Both practices had similar outcomes. Further efforts are needed to explore new and cost-effective team-based care delivery models that improve process, outcomes, and continuity of care, as well as patient care experiences.

Enabling Services Improve Access To Care, Preventive Services, And Satisfaction Among Health Center Patients

Enabling services address a combination of social determinants of health and barriers to access to primary care and are intended to reduce health disparities. They include care coordination; health education; transportation; and assistance with obtaining food, shelter, and benefits. Empirical evidence of enabling services' potential contribution to health outcomes is limited, which impedes their widespread dissemination. We examined how the receipt of enabling services influenced patient health care outcomes based on a nationally representative survey of patients served in 2014 at health centers funded by the Health Resources and Services Administration. We compared enabling services users and nonusers and found that enabling services were associated with 1.92 more health center visits, an 11.78-percentage-point higher probability of getting a routine checkup, a 16.34-percentage-point higher likelihood of having had a flu shot, and a 7.63-percentage-point higher probability of patient satisfaction. Our results confirm the value of systematic delivery of enabling services in reducing access barriers and improving patient satisfaction.

Quality of Care and Preventive Screening Use in the CareFirst Patient-Centered Medical Home Program

Despite their value, comprehensive diabetes care and screening for common cancers remain underutilized. We examined the association between participation in a patient-centered medical home (PCMH) program with strong financial incentives and receipt of preventive care in the first 5 years after program launch. Using multivariate regression analysis, we compared outcomes for adults under the care of participating primary care providers (PCPs) with adults under the care of nonparticipating PCPs. Outcomes were breast, cervical and colorectal cancer screenings, and elements of diabetes care. The analytic sample included 818,623 adults living in Maryland, Virginia, or the District of Columbia, and enrolled with CareFirst for at least 1 year during 2010-2015. By Year 5, enrollees in the intervention group were 7.9 (95% confidence interval [CI]: 2.8-13.0), 6.1 (95% CI: 1.4-10.7), 3.1 (95% CI: 2.1-4.0), and 7.6 (95% CI: 7.0-8.2) percentage points more likely to undergo HbA1c tests, nephropathy examinations, breast, and cervical cancer screenings, respectively. We found no significant change in the propensity to receive colorectal cancer screening or an eye examination. Our study shows that a PCMH program with strong financial incentives can raise the provision of preventive care but could require additional adjustment.

Analysis of the relationship between treatment networks and the evolution of patients with Type 2 Diabetes Mellitus

Type 2 Diabetes Mellitus (T2DM) is a chronic disease that has been increasing in prevalence in recent years and that can cause severe complications. To ensure patient care is administered correctly, it is necessary for medical treatment teams to be both multidisciplinary and cohesive. The analysis of health processes is a constant challenge due to their high variability and complexity. This paper proposes a method based on the analysis of social networks to detect treatment networks, and to identify a relationship between these networks and patient evolution, as measured by glycated hemoglobin (HbA1c) levels. The networks were segmented based on patient adherence to their medical appointments and their mean time of delay. We applied this method on a sample of 1574 patients diagnosed with T2DM. Results show that participatory treatment -in which a patient sees a particular group of professionals on a recurrent basis - together with high levels of adherence are associated to those patients who improve their HbA1c levels in the case of high levels of adherence, while those who continually experience referrals to different professionals, remain unstable and, in some cases, get worse. On the other hand, in order to maintain a patient as stable, continuous control of the patient is enough, regardless of the recurrence to the same professionals.

Organizational Conditions That Impact the Implementation of Effective Team-Based Models for the Treatment of Diabetes for Low Income Patients-A Scoping Review

Background: Team-based care models (TBC) have demonstrated effectiveness to improve health outcomes for vulnerable diabetes patients but have proven difficult to implement in low income settings. Organizational conditions have been identified as influential on the implementation of TBC. This scoping review aims to answer the question: What is known from the scientific literature about how organizational conditions enable or inhibit TBC for diabetic patients in primary care settings, particularly settings that serve low-income patients? Methods: A scoping review study design was selected to identify key concepts and research gaps in the literature related to the impact of organizational conditions on TBC. Twenty-six articles were finally selected and included in this review. This scoping review was carried out following a directed content analysis approach. Results: While it is assumed that trained health professionals from diverse disciplines working in a common setting will sort it out and work as a team, co-location, and health professions education alone do not improve patient outcomes for diabetic patients. Health system, organization, and/or team level factors affect the way in which members of a care team, including patients and caregivers, collaborate to improve health outcomes. Organizational factors span across seven categories: governance and policies, structure and process, workplace culture, resources, team skills and knowledge, financial implications, and technology. These organizational factors are cited throughout the literature as important to TBC, however, research on the organizational conditions that enable and inhibit TBC for diabetic patients is extremely limited. Dispersed organizational factors are cited throughout the literature, but only one study specifically assesses the effect of organizational factors on TBC. Thematic analysis was used to categorize organizational factors in the literature about TBC and diabetes and a framework for analysis and definitions for key terms is presented. Conclusions: The review identified significant gaps in the literature relating to the study of organizational conditions that enable or inhibit TBC for low-income patients with diabetes. Efforts need to be carried out to establish unifying terminology and frameworks across the field to help explain the relationship between organizational conditions and TBC for diabetes. Gaps in the literature include research be based on organizational theories, research carried out in low-income settings and low and middle income countries, research explaining the difference between the organizational conditions that impact the implementation of TBC vs. maintaining or sustaining TBC and the interaction between organizational factors at the micro, meso and macro level and their impact on TBC. Few studies include information on patient outcomes, and fewer include information on low income settings. Further research is necessary on the impact of organizational conditions on TBC and diabetic patient outcomes.

Core Functions and Forms of Complex Health Interventions: a Patient-Centered Medical Home Illustration

Despite policy and practice support to develop and test interventions designed to increase access to quality care among high-need patients, many of these interventions fail to meet expectations once deployed in real-life clinical settings. One example is the Patient-Centered Medical Home (PCMH) model, designed to deliver coordinated care. A meta-analysis of PCMH initiatives found mixed evidence of impacts on service access, quality, and costs. Conceptualizing PCMH as a complex health intervention can generate insights into the mechanisms by which this model achieves its effects. It can also address heterogeneity by distinguishing PCMH core functions (the intervention's basic purposes) from forms (the strategies used to meet each function). We conducted a scoping review to identify core functions and forms documented in published PCMH models from 2007 to 2017. We analyzed and summarized the data to develop a PCMH Function and Form Matrix. The matrix contributes to the development of an explicit theory-based depiction of how an intervention achieves its effects, and can guide decision-support tools in the field. This innovative approach can support transformations of clinical settings and implementation efforts by building on a clear understanding of the intervention's standard core functions and the forms adapted to local contexts' characteristics.

Risk Factors for Below-the-Knee Amputation in Diabetic Foot Osteomyelitis After Minor Amputation

BACKGROUND

Below-the-knee amputation (BKA) can be a detrimental outcome of diabetic foot osteomyelitis (DFO). Ideal treatment of DFO is controversial, but studies suggest minor amputation reduces the risk of BKA. We evaluated risk factors for BKA after minor amputation for DFO.

METHODS

This is a retrospective cohort of patients discharged from Denver Health Medical Center from February 1, 2012, through December 31, 2014. Patients who underwent minor amputation for diagnosis of DFO were eligible for inclusion. The outcome evaluated was BKA in the 6 months after minor amputation.

RESULTS

Of 153 episodes with DFO that met the study criteria, 11 (7%) had BKA. Failure to heal surgical incision at 3 months (P < .001) and transmetatarsal amputation (P = .009) were associated with BKA in the 6 months after minor amputation. Peripheral vascular disease was associated with failure to heal but not with BKA (P = .009). Severe infection, bacteremia, hemoglobin A_1c, and positive histopathologic margins of bone and soft tissue were not associated with BKA. The median antibiotic duration was 42 days for positive histopathologic bone resection margin (interquartile range, 32-47 days) and 16 days for negative margin (interquartile range, 8-29 days). Longer duration of antibiotics was not associated with lower risk of BKA.

CONCLUSIONS

Patients who fail to heal amputation sites in 3 months or who have transmetatarsal amputation are at increased risk for BKA. Future studies should evaluate the impact of aggressive wound care or whether failure to heal is a marker of another variable.

Impact of Physician-Pharmacist Covisits at a Primary Care Clinic in Patients With Uncontrolled Diabetes

PURPOSE

A popular method for enhancing medication management within a patient-centered medical home (PCMH) is the physician-pharmacist collaborative management (PPCM) model. To improve efficiency of health-care delivery within 4 federally qualified health centers (FQHCs), the PPCM model was implemented through coordinated physician-pharmacist covisits.

OBJECTIVE

To evaluate the impact of physician-pharmacist covisits on clinical outcomes among patients with uncontrolled diabetes.

METHODOLOGY

This was a retrospective multicenter cohort study including adults (≥18 years old) with uncontrolled type 1 or type 2 diabetes (hemoglobin A_1c [HbA_1c] ≥ 8 %) who had at least one covisit between January 1, 2013, and October 1, 2016. The primary clinical metric was mean change in HbA_1c from baseline to follow-up. Secondary outcomes included adherence to select American Diabetes Association (ADA) Standards of Medical Care.

RESULTS

A total of 106 patients were included in this analysis. Patients who were managed in the PPCM model experienced a significant decrease in mean change in HbA_1c from baseline to follow-up (-1.75 [2.63], P < .001). There was no significant difference in the proportion of patients receiving recommended vaccinations or cardiovascular (CV) risk reduction medications.

CONCLUSION

The results suggest that physician-pharmacist covisits may improve glucose control in patients with uncontrolled diabetes.

Pneumococcal Vaccine Coverage in Adults Aged 19-64 Years, Newly Diagnosed With Chronic Conditions in the U.S

INTRODUCTION

This study examined pneumococcal vaccine coverage in adults aged 19-64 years newly diagnosed with diabetes, chronic heart, lung, or liver disease. These conditions are indicated for pneumococcal vaccination by the Advisory Committee on Immunization Practices.

METHODS

A retrospective cohort analysis was conducted in 2016 using the Truven Health MarketScan® database. The study population was adults aged 19-64 years with at least one new chronic condition during 2009-2013 and continuous health plan enrolment for 2 years before and 1 year after the initial diagnosis. Vaccine coverage by length of follow-up since diagnosis (ranging from 1 to 5 years) was summarized. Multivariate analyses were performed to understand factors associated with vaccination.

RESULTS

A total of 552,942 adults aged 19-64 years with chronic conditions were identified. There were 8% of adults newly diagnosed with one of four chronic conditions that received a pneumococcal vaccination after 1 year of follow-up; the proportion increased to 20.1% among those with 5 years of follow-up data. Adults aged 50-64 years were more likely to be vaccinated than those aged 19-49 years. Adults with diabetes were more likely to be vaccinated than adults with chronic heart, lung, or liver disease. Adults enrolled in HMO plans were more likely to be vaccinated than adults in other plan types. A higher number of healthcare encounters increased the likelihood of vaccination. Adults who received influenza vaccination were also more likely to receive a pneumococcal vaccination.

CONCLUSIONS

Vaccine coverage remains well below Healthy People 2020 targets. A substantial number of adults with chronic conditions remain unvaccinated and at risk for pneumococcal disease.

Synthesis Of Research On Patient-Centered Medical Homes Brings Systematic Differences Into Relief

The patient-centered medical home (PCMH) model emphasizes comprehensive, coordinated, patient-centered care, with the goals of reducing spending and improving quality. To evaluate the impact of PCMH initiatives on utilization, cost, and quality, we conducted a meta-analysis of methodologically standardized findings from evaluations of eleven major PCMH initiatives. There was significant heterogeneity across individual evaluations in many outcomes. Across evaluations, PCMH initiatives were not associated with changes in the majority of outcomes studied, including primary care, emergency department, and inpatient visits and four quality measures. The initiatives were associated with a 1.5 percent reduction in the use of specialty visits and a 1.2 percent increase in cervical cancer screening among all patients, and a 4.2 percent reduction in total spending (excluding pharmacy spending) and a 1.4 percent increase in breast cancer screening among higher-morbidity patients. These associations were significant. Identification of the components of PCMHs likely to improve outcomes is critical to decisions about investing resources in primary care.

Diabetes care improvement in pharmacist- versus nurse-supported patient-centered medical homes

OBJECTIVES

In 2009 and 2010, 17 primary care sites within 1 healthcare system became patient-centered medical homes (PCMHs), but the sites trained different personnel (pharmacists vs nurses) to improve diabetes care using self-management support (SMS). We report the challenges and successes of our efforts to: 1) assemble a new multipayer (Medicare, Medicaid, commercial) claims dataset linked to a clinical registry and 2) use the new dataset to perform comparative effectiveness research on implementation of the 2 SMS models.

STUDY DESIGN

Longitudinal cohort study.

METHODS

We lost permission to use private-payer data. Therefore, we used claims from Medicare fee-for-service and Medicare/Medicaid dual-eligible patients merged with chronic disease registry data. We studied 2008 to 2010, which included 1 year pre- and 1 year post the 2009 implementation time period. Outcomes were outpatient and emergency department visits, hospitalizations, care process (use of statin), and 3 intermediate outcomes (glycemic control, blood pressure [BP], and low-density lipoprotein cholesterol [LDL-C]).

RESULTS

In our sample of 2826 patients, quality of care improved and utilization decreased over the 2.5 years. Both approaches improved lipid control (LDL-C decreased by an average of 4 mg/dL for pharmacy-SMS and 5.6 mg/dL for nurse-SMS) and diastolic BP (-1.5 mm Hg for pharmacy-SMS and -1.3 mm Hg for nurse-SMS), whereas only the pharmacy-led approach decreased primary care visits (by 0.8 visits). The groups differed slightly on 2 measures (glycated hemoglobin, systolic BP) with respect to the trajectory of improvement over time, but performance was similar by 2.5 years.

CONCLUSIONS

Diabetes care improved during PCMH implementation systemwide, supporting both nurse-led and pharmacist-led SMS models.

Patient-Centered Medical Home Recognition and Diabetes Control Among Health Centers: Exploring the Role of Enabling Services

The patient-centered medical home (PCMH) model has been considered a promising approach to improve chronic care delivery, particularly among patients with diabetes. There is theoretical support to suggest that certain nonmedical services, such as enabling services (eg, case management, social work, transportation), embedded within PCMH could be contributing to successful model implementation. It remains unclear whether PCMH recognition or enabling services are related to diabetes control. Federally Qualified Health Centers (FQHCs) are an important setting in which to study this relationship given the considerable effort required to implement the PCMH model and the ubiquity of enabling services in these safety net settings. This cross-sectional, population-based study used 2012 data from the Health Resources and Services Administration's Uniform Data System and PCMH Recognition Initiative Dataset to determine whether PCMH recognition status was associated with diabetes control rates among FQHCs, while controlling for covariates including enabling services. The study linear regression model estimated that PCMH recognition was associated with a 1.5% increase in the proportion of patients with controlled diabetes (B = 0.015; 95% CI 0.002, 0.027). Clinic region, patient age, and race/ethnicity groups also were related to diabetes control; however, enabling services were not. These findings suggest there is a positive association between PCMH recognition and diabetes control rates among FQHCs. Future research, using data that accurately reflect the provision and utilization of PCMH primary care functions and related enabling services, is needed to fully understand the relationship between the PCMH model and population health measures such as diabetes control.

For Diabetes Shared Savings Programs, 1 Year of Data Is Not Enough

Fee-for-service payment models are moving toward pay-for-performance designs, many of which rely on shared savings for financial sustainability. Shared savings programs divide the cost savings between health care purchaser and provider based on provider performance. Often, these programs measure provider performance as the delivery of agreed-upon clinical practice guidelines that usually are represented as evidence-based medicine (EBM). Multiyear studies show a negative relationship between total cost and EBM, indicating that long-term shared savings can be substantial. This study explores expectations for the rewards in the first year of a shared savings program. It also indicates the effectiveness of using 1 year of claims to assess cost savings from evidence-based care, especially in a patient population with high turnover. This study analyzed 1956 adults with diabetes insured through Medicaid. Results of linear regression showed that the relationship between total cost of care and each element of evidence-based medical care during a 1-year period was positive (higher cost) or insignificant. The results indicate that diabetes EBM programs cannot expect to see significant cost savings if the evaluation lasts only 1 year or less. The study concludes that improvements in EBM incentive programs could come from investigating the length of time needed to realize cost savings from each element of diabetes EBM. Investigating other factors that could affect the expected amount of cost savings also would benefit these programs, especially factors derived from sources external to insurance program information such as the medical record and care management data.

Redesigning Diabetes Care: Defining the Role of Endocrinologists Among Alternative Providers

The current diabetes epidemic threatens to overwhelm the healthcare system unless we redesign how diabetes care is delivered. The number of endocrinologists is grossly inadequate to provide care for all individuals with diabetes, but with the appropriate utilization of the primary care workforce and alternative healthcare providers working together in teams, effective diabetes care can be provided to all. We propose a patient-centered, goal-based approach with resources devoted to care coordination, measurement of outcomes, appropriate use of technology, and measurement of patient satisfaction. Financial incentives to healthcare systems and providers need to be based on defined outcome measures and reducing long-term total medical expenditures, rather than reimbursement based on number of visits and lengthy documentation. Endocrinologists have a responsibility in setting up effective diabetes care delivery systems within their organizations, in addition to delivering diabetes care and serving as a resource for the educational needs for other medical professionals in the community. There are major challenges to implementing such systems, both at the financial and organizational levels. We suggest a stepwise implementation of discrete components based on the local priorities and resources and provide some examples of steps we have taken at our institution.

Fibromyalgia: management strategies for primary care providers

AIMS

Fibromyalgia (FM), a chronic disorder defined by widespread pain, often accompanied by fatigue and sleep disturbance, affects up to one in 20 patients in primary care. Although most patients with FM are managed in primary care, diagnosis and treatment continue to present a challenge, and patients are often referred to specialists. Furthermore, the lack of a clear patient pathway often results in patients being passed from specialist to specialist, exhaustive investigations, prescription of multiple drugs to treat different symptoms, delays in diagnosis, increased disability and increased healthcare resource utilisation. We will discuss the current and evolving understanding of FM, and recommend improvements in the management and treatment of FM, highlighting the role of the primary care physician, and the place of the medical home in FM management.

METHODS

We reviewed the epidemiology, pathophysiology and management of FM by searching PubMed and references from relevant articles, and selected articles on the basis of quality, relevance to the illness and importance in illustrating current management pathways and the potential for future improvements.

RESULTS

The implementation of a framework for chronic pain management in primary care would limit unnecessary, time-consuming, and costly tests, reduce diagnostic delay and improve patient outcomes.

DISCUSSION

The patient-centred medical home (PCMH), a management framework that has been successfully implemented in other chronic diseases, might improve the care of patients with FM in primary care, by bringing together a team of professionals with a range of skills and training.

CONCLUSION

Although there remain several barriers to overcome, implementation of a PCMH would allow patients with FM, like those with other chronic conditions, to be successfully managed in the primary care setting.

Comprehensive Care for People With Diabetic Kidney Disease

IN BRIEF Diabetic kidney disease carries a heavy burden, both economically and in terms of quality of life, largely because of its very high risk for vascular disease. Coordinated, multidisciplinary care with attention to appropriate, timely screening and preventive management is crucial to reducing the morbidity and mortality of this devastating disease.

Outside the exam room: policies for connecting clinic to community in diabetes prevention and treatment

The public health burden and racial/ethnic, sex, and socioeconomic disparities in obesity and in diabetes require a population-level approach that goes beyond provision of high-quality clinical care. The Robert Wood Johnson Foundation’s Commission to Build a Healthier America recommended 3 strategies for improving the nation’s health: 1) invest in the foundations of lifelong physical and mental well-being in our youngest children; 2) create communities that foster health-promoting behaviors; and 3) broaden health care to promote health outside the medical system. We present an overview of evidence supporting these approaches in the context of diabetes and suggest policies to increase investments in 1) adequate nutrition through breastfeeding and other supports in early childhood, 2) community and economic development that includes health-promoting features of the physical, food, and social environments, and 3) evidence-based interventions that reach beyond the clinical setting to enlist community members in diabetes prevention and management.
