Inflammatory bowel diseases (IBDs) including Crohn’s disease and ulcerative colitis are life-long chronic diseases with high morbidity. There has been remarkable progress in the understanding of disease pathophysiology, leading to new medical therapies and surgical approaches for the management of IBD. These trends have resulted in a marked increase in the cost of IBD care, with current estimates ranging from $14 to $31 billion in both direct and indirect costs in the United States.1

IBD patients have unique behavioral, preventive, and therapeutic care requirements.2,3 Because of the complexity of care, there is a large degree of segmentation and fragmentation of IBD management across health care systems and among multiple providers. This siloed approach often falls short of seamless, efficient, high-quality, patient-centered care.

To address the increasing costs and fragmentation of chronic disease management, population-based health care has emerged as a new concept with an emphasis on reward for value, not volume. Two such examples of population-based health care include accountable care organizations and patient-centered medical homes. This concept relies on the development of new payment models and shifts the risk to the providers.4,5 Primary care providers play a central coordinating role in these new models.6,7 However, the role of specialists is less well defined, with limited sharing of risk for the care and costs of populations.

The IBD specialty medical home (SMH) implemented at the University of Pittsburgh Medical Center (UPMC) is an example of a new model of care. The IBD SMH is constructed to align incentives and provide up-front resources to manage a population of patients with IBD optimally – including treatment of their inflammatory disease, coexisting pain, and psychological issues.8-10 In the case of the IBD SMH, the gastroenterologist is the principal provider for a cohort of IBD patients. The gastroenterologist is responsible for the coordination and management of health care of this population and places the IBD patient at the center of the medical universe.

In this article, we draw from our rich partnership between the UPMC Health Plan (HP) and Health System to describe the construction and deployment of the IBD SMH. Although this model is new and we still are learning, we already have seen an improvement in the overall quality of life, decreased utilization, and reduction in total cost of care for this IBD SMH population.
 

Constructing an IBD medical home: where to begin?

In conjunction with the UPMC HP, we designed and established an IBD patient-centered SMH, designated in July 2015 as UPMC Total Care–Inflammatory Bowel Disease.11 The development of the medical home was facilitated by our unique integrated delivery and finance system. The UPMC HP provided important utilization data on their IBD population, which allowed for focused enrollment of the highest-utilizer patients. In addition, the UPMC HP funded positions that we hired directly as employees of our IBD SMH. These positions included the following: two nurse coordinators, two certified nurse practitioners, a dietitian, a social worker, and a psychiatrist. The UPMC HP also provided their own HP employees to work with our IBD SMH: The rare and chronic disease team included two nurses and a social worker who made house calls for a select group of patients (identified based on the frequency of their health care use). The HP also provided health coaches who worked directly with our patients on lifestyle modifications, such as smoking cessation and exercise programs. Finally, the UPMC HP worked with the IBD SMH to provide support for a variety of operational functions. Examples of these important efforts included data analytics through their department of health economics, regular collaboration to assist the provider team in modifying the program, publicizing the IBD SMH to their members, and facilitating approval of IBD medications through their pharmacy department.

We acknowledge that the development and implementation of an IBD SMH will vary from region to region and depend on the relationship of payers and providers. Thus, the blueprint of our UPMC IBD Medical Home may not be replicated readily in other centers or regions. However, there are several core elements that we believe are necessary in constructing any SMH: 1) a payer willing to partner with the provider, 2) a patient population with specific characteristics, 3) a physician champion, and 4) prespecified goals and measures of success.
 

Payer or health plan

A SMH is based on the premise that providers and payers working together can achieve more efficient, high-quality care for patients than either party working alone. Payers have essential resources for infrastructure support, preventive services delivery, marketing and engagement expertise, large databases for risk stratification and gap closure, and care management capacity to be a valuable partner. In the short term, philanthropy, grants, and crowd-sourcing options can be used to provide initial support for components of the SMH; however, these rarely are sustainable long-term options. Thus, the most critical collaboration necessary to considering a SMH is between payer(s) (insurance company or health plan) and the specialty provider.

 

 

Ideally, the local environment should consist of a single or a few large payers to ease SMH implementation. UPMC is a large integrated delivery (25 hospitals and more than 600 clinics) and financing system (more than 3 million members and is the dominant payer in the region), with a history of leveraging payer–provider partnerships to achieve better patient care, education, and research, and thus served as an ideal collaborator in the design and launch of the IBD SMH. Most physicians in the United States do not work in an integrated payer–provider health delivery system, and partnering with a large regional payer with an interest in specialty population-based chronic care is reasonable for constructing an SMH in your medical neighborhood.
 

Patient population

In addition to having a collaborative health plan with large population coverage, there must exist a substantial IBD population managed by gastroenterologists. There must be a sufficient number of high-utilizer, high-cost members to justify up-front capital expenditure and return on investment. To determine the feasibility and utility of creating an IBD SMH at UPMC, we collected baseline data on the following: 1) the number of IBD patients within our IBD center and health plan, 2) a hotspotting analysis for our Pennsylvania counties, and 3) health care utilization of the IBD population of interest. At the time of the SMH inception, there were 6,319 Crohn’s disease and ulcerative colitis patients (including all insurance plans) in our center, with more than 3,500 members insured by our HP. There was a 30% increase in new IBD patients to our center in the 3 years before starting the IBD SMH, and the HP had a 27% increase in overall IBD members. Based on a regional hotspotting analysis, $24.3 million of the annual total of $36.9 million was related to hospitalization costs from our IBD patients. The high-utilizer patients accounted for most of the total cost of care for our HP; 16% accounted for 48% of the per-member per-month cost and 29% accounted for 79% of the total annual cost. These baseline data supported justification for an IBD SMH.

Although there is no absolute minimum number of members (patients) required, and the SMH model can be scaled to various IBD populations, we believe that at least 1,000 patients covered by a single insurer must exist. The justification for the 1,000 patients is an estimate of the number of high-utilizer patients who would be required to justify a cost savings, and ultimately a return on investment. We calculated that at least 300 high-utilizer patients would need to be included in our IBD SMH to show a reduction in health care utilization and total cost of care. Therefore, if we assume that approximately 30% of any chronic disease population drives the majority of cost and represents the highest utilizers, we estimated that at least 1,000 patients should be covered by a single insurer.

For development of an SMH, there are two approaches that may be taken: Design the medical home for the entire Health Plan’s population of patients with the disease of interest, or focus only on the high-utilizing, most expensive patients. The latter will include a more complex and challenging cohort of patients, but likely will provide the opportunity to show a reduction in utilization and total cost of care than a broader all-comers population approach.



Physician champions

A successful SMH requires a physician (or health care provider) champion. IBD care within the SMH is unique and distinct from gastroenterologists’ classic training and specialty care. In addition to addressing the biologic disease, the emphasis is on whole-patient care: preventive care, behavioral medicine, socioeconomic considerations of the patient, and provision of care for nongastrointestinal symptoms and diseases. In an SMH, the specialist must be willing to incorporate and address all facets of health care to improve patient outcomes.

Goals and measures of success

To ensure successful deployment of an SMH, it is important to establish shared payer–provider goals and metrics during the construction phase of the medical home. These goals should include an enrollment target number for each year, quality improvement metrics, patient experience outcomes, and metrics for a reduction in health care utilization and total cost of care. Examples of our IBD SMH year 1 and year 2 goals are outlined in Supplementary Table 1 (at http://dx.doi.org/10.1016/j.cgh.2017.05.026). In the first year of our IBD SMH, we were able to achieve our goals, and publication of our results is forthcoming. We have enrolled more than 325 patients, retained 90%, reduced emergency room visits and hospitalizations by 50%, and significantly improved quality of life. Most of our patients have been assigned an HP coach and use the electronic medical portal to communicate with the medical home. Our patient satisfaction for physician communication was 99%.

 

 

Key components of the IBD medical home

Based on our experience, we believe the following are key components of a successful IBD SMH: 1) team-based care with physician extenders, nurse coordinators, schedulers, social workers, and dietitians as essential members of the IBD SMH; 2) effective care coordination to reduce barriers to comprehensive biopsychosocial care; 3) tracking of process and outcome metrics of interest; 4) appropriate use of technology to enhance clinical care; and 5) care access (e.g., open-access appointments), after-hours care, and follow-up care after emergency room visits and hospitalizations (Table 1).

Essential components of an inflammatory bowel disease specialty medical home
There is not a one-size-fits-all SMH model given the range of different subspecialty practices. The appropriate dose for each specific setting may vary, and we recommend an iterative deployment process starting with a few case studies and then sequentially rolling out to a larger-scale clinical sample. The goal of the initial SMH is to show feasibility and understand which components are most critical for successful implementation.

Although the eventual goal of an IBD SMH is to consolidate health care for all IBD patients, the initial launch stages are more likely to succeed if the SMH focuses on the subgroup of IBD patients who use health care excessively, often in an unplanned fashion (e.g., emergency department visits or hospitalizations). In conjunction with a payer, it is easy to identify the most costly IBD patients in a cohort. For example, for initial enrollment, the UPMC IBD SMH selected patients between the ages of 18 and 55 years, with confirmed Crohn’s disease or ulcerative colitis, and evidence that IBD was a primary driver of patients’ health care utilization; the latter was defined if the majority of health care expenditures in the prior year was related to IBD (as judged by International Classification of Diseases, 9th and 10th revisions, primary and secondary diagnoses).
 

Team-based care

A central component to our IBD SMH was the creation of an integrated team. Supplementary Table 2 (at http://dx.doi.org/10.1016/j.cgh.2017.05.026) describes various positions that are vital for a successful SMH. For a team approach to be most effective, there needs to be clear definitions or roles and role overlaps so that team members can work as a cohesive, organized, and efficient unit. Physician extenders are critical to the model’s success and are trained to make routine IBD care decisions, provide basic primary care, and coordinate care with the gastroenterologist to meet patient needs. The staff-to-patient ratio requirements may vary from region to region and from SMH to SMH. The nurse coordinators and physician extenders assume the burden of day-to-day patient care, and are supervised by the gastroenterologist and psychiatrist. In our UPMC IBD SMH, the ratio of one nurse coordinator and one certified nurse practitioner per 500 patients is sufficient. In addition, one social worker, one dietitian, one scheduler, one gastroenterologist, and one psychiatrist per 1,000 patients is our current model. To date, we have enrolled more than 500 patients, and through funding from our UPMC HP, we have just hired our second nurse coordinator and second nurse practitioner in anticipation of 1,000 patients by year 4.

Figure 1
In an ideal team model, all staff, both behavioral and medical, are trained in basic behavioral assessment and interventions, motivational interviewing, and disease self-management techniques so that the behavioral health specialist can be considered a second-line provider or a consultant to the gastroenterologist for the most complex psychiatric patients. Figure 1 shows a typical patient’s trajectory through the IBD SMH.
 

Care coordination and incorporation of technology

The team composition is organized to provide tiered care for optimal efficiency. For such a stepped care model to be effective and scalable, two components are essential. The first component is a care coordination system that allows for the reliable classification of the biological, psychological, social, and health systems barriers faced by patients. To this end, our SMH developed an IBD-specific complexity grid (Supplementary Table 3; at http://dx.doi.org/10.1016/j.cgh.2017.05.026) that was derived from a primary care model.12 The second component is the use of technology-enhanced care to scale delivery of services in a population health model. Examples of technology in our SMH include the use of telemedicine/telepsychiatry by secure video, health coach virtual visits, remote monitoring, and provider-assisted behavioral interventions that patients can access on their smart phones.

New payment models for specialty medical homes

The SMH transitions away from relative value unit–based reimbursement and toward a value-based paradigm. In the SMH, the gastroenterologist serves as the principal medical provider for the IBD patient. Both providers and payers will be able to refer patients to the SMH. Data on quality metrics will be tracked and physician extenders and nurse coordinators will help ensure that goals are met. Quality improvement, preventive medicine, telemedicine, and point-of-contact mental health care will replace the volume-based relative value unit system.

 

 

Alternative payment models will be required to support the SMH. Because of the novel nature of the SMH, the optimal payment model has yet to be determined, but probably will include either a shared savings or global cap approach, with an emphasis on the total cost of care reduction. This means that the specialist in the SMH must be aware of all care, and the cost of care, that the patient receives. Biologics and other IBD therapy costs are high and will continue to increase. The sustainable model must be sufficiently supple to not disincentivize the provider to use proven and effective, albeit expensive, therapy for patients who need it most. A close working relationship between the SMH providers and the health plan chief pharmacy officer will be essential. We expect that appropriate use of medications will lead to a medical cost offset with improved IBD outcomes, a reduction in health care utilization, and optimized work and life productivity.
 

Conclusions

In new models of care, specialty providers partner with payers in a patient-centered system to provide principal care for patients with chronic diseases, including IBD, in an effort to reduce costs and provide efficient, high-quality care. These models will require close collaborations with payers, a sufficiently large patient population, a physician champion, and a multidisciplinary staff targeting various aspects of health care. Successful implementation of such models will help reduce costs of care while improving the patient-centered experience and outcomes.

To ensure successful deployment of an SMH, it is important to establish shared payer–provider goals and metrics during the construction phase of the medical home. These goals should include an enrollment target number for each year, quality improvement metrics, patient experience outcomes, and metrics for a reduction in health care utilization and total cost of care. Examples of our IBD SMH year 1 and year 2 goals are outlined in Supplementary Table 1 (at http://dx.doi.org/10.1016/j.cgh.2017.05.026). In the first year of our IBD SMH, we were able to achieve our goals, and publication of our results is forthcoming.

We expect that appropriate use of medications will lead to a medical cost offset with improved IBD outcomes, a reduction in health care utilization, and optimized work and life productivity.
 

Conclusions

In new models of care, specialty providers partner with payers in a patient-centered system to provide principal care for patients with chronic diseases, including IBD, in an effort to reduce costs and provide efficient, high-quality care. These models will require close collaborations with payers, a sufficiently large patient population, a physician champion, and a multidisciplinary staff targeting various aspects of health care. Successful implementation of such models will help reduce costs of care while improving the patient-centered experience and outcomes.

Inflammatory bowel diseases (IBDs) including Crohn’s disease and ulcerative colitis are life-long chronic diseases with high morbidity. There has been remarkable progress in the understanding of disease pathophysiology, leading to new medical therapies and surgical approaches for the management of IBD. These trends have resulted in a marked increase in the cost of IBD care, with current estimates ranging from $14 to $31 billion in both direct and indirect costs in the United States.1

IBD patients have unique behavioral, preventive, and therapeutic care requirements.2,3 Because of the complexity of care, there is a large degree of segmentation and fragmentation of IBD management across health care systems and among multiple providers. This siloed approach often falls short of seamless, efficient, high-quality, patient-centered care.

To address the increasing costs and fragmentation of chronic disease management, population-based health care has emerged as a new concept with an emphasis on reward for value, not volume. Two such examples of population-based health care include accountable care organizations and patient-centered medical homes. This concept relies on the development of new payment models and shifts the risk to the providers.4,5 Primary care providers play a central coordinating role in these new models.6,7 However, the role of specialists is less well defined, with limited sharing of risk for the care and costs of populations.

The IBD specialty medical home (SMH) implemented at the University of Pittsburgh Medical Center (UPMC) is an example of a new model of care. The IBD SMH is constructed to align incentives and provide up-front resources to manage a population of patients with IBD optimally – including treatment of their inflammatory disease, coexisting pain, and psychological issues.8-10 In the case of the IBD SMH, the gastroenterologist is the principal provider for a cohort of IBD patients. The gastroenterologist is responsible for the coordination and management of health care of this population and places the IBD patient at the center of the medical universe.

In this article, we draw from our rich partnership between the UPMC Health Plan (HP) and Health System to describe the construction and deployment of the IBD SMH. Although this model is new and we still are learning, we already have seen an improvement in the overall quality of life, decreased utilization, and reduction in total cost of care for this IBD SMH population.
 

Constructing an IBD medical home: where to begin?

In conjunction with the UPMC HP, we designed and established an IBD patient-centered SMH, designated in July 2015 as UPMC Total Care–Inflammatory Bowel Disease.11 The development of the medical home was facilitated by our unique integrated delivery and finance system. The UPMC HP provided important utilization data on their IBD population, which allowed for focused enrollment of the highest-utilizer patients. In addition, the UPMC HP funded positions that we hired directly as employees of our IBD SMH. These positions included the following: two nurse coordinators, two certified nurse practitioners, a dietitian, a social worker, and a psychiatrist. The UPMC HP also provided their own HP employees to work with our IBD SMH: The rare and chronic disease team included two nurses and a social worker who made house calls for a select group of patients (identified based on the frequency of their health care use). The HP also provided health coaches who worked directly with our patients on lifestyle modifications, such as smoking cessation and exercise programs. Finally, the UPMC HP worked with the IBD SMH to provide support for a variety of operational functions. Examples of these important efforts included data analytics through their department of health economics, regular collaboration to assist the provider team in modifying the program, publicizing the IBD SMH to their members, and facilitating approval of IBD medications through their pharmacy department.

We acknowledge that the development and implementation of an IBD SMH will vary from region to region and depend on the relationship of payers and providers. Thus, the blueprint of our UPMC IBD Medical Home may not be replicated readily in other centers or regions. However, there are several core elements that we believe are necessary in constructing any SMH: 1) a payer willing to partner with the provider, 2) a patient population with specific characteristics, 3) a physician champion, and 4) prespecified goals and measures of success.
 

Payer or health plan

A SMH is based on the premise that providers and payers working together can achieve more efficient, high-quality care for patients than either party working alone. Payers have essential resources for infrastructure support, preventive services delivery, marketing and engagement expertise, large databases for risk stratification and gap closure, and care management capacity to be a valuable partner. In the short term, philanthropy, grants, and crowd-sourcing options can be used to provide initial support for components of the SMH; however, these rarely are sustainable long-term options. Thus, the most critical collaboration necessary to considering a SMH is between payer(s) (insurance company or health plan) and the specialty provider.

 

 

Ideally, the local environment should consist of a single or a few large payers to ease SMH implementation. UPMC is a large integrated delivery (25 hospitals and more than 600 clinics) and financing system (more than 3 million members and is the dominant payer in the region), with a history of leveraging payer–provider partnerships to achieve better patient care, education, and research, and thus served as an ideal collaborator in the design and launch of the IBD SMH. Most physicians in the United States do not work in an integrated payer–provider health delivery system, and partnering with a large regional payer with an interest in specialty population-based chronic care is reasonable for constructing an SMH in your medical neighborhood.
 

Patient population

In addition to having a collaborative health plan with large population coverage, there must exist a substantial IBD population managed by gastroenterologists. There must be a sufficient number of high-utilizer, high-cost members to justify up-front capital expenditure and return on investment. To determine the feasibility and utility of creating an IBD SMH at UPMC, we collected baseline data on the following: 1) the number of IBD patients within our IBD center and health plan, 2) a hotspotting analysis for our Pennsylvania counties, and 3) health care utilization of the IBD population of interest. At the time of the SMH inception, there were 6,319 Crohn’s disease and ulcerative colitis patients (including all insurance plans) in our center, with more than 3,500 members insured by our HP. There was a 30% increase in new IBD patients to our center in the 3 years before starting the IBD SMH, and the HP had a 27% increase in overall IBD members. Based on a regional hotspotting analysis, $24.3 million of the annual total of $36.9 million was related to hospitalization costs from our IBD patients. The high-utilizer patients accounted for most of the total cost of care for our HP; 16% accounted for 48% of the per-member per-month cost and 29% accounted for 79% of the total annual cost. These baseline data supported justification for an IBD SMH.

Although there is no absolute minimum number of members (patients) required, and the SMH model can be scaled to various IBD populations, we believe that at least 1,000 patients covered by a single insurer must exist. The justification for the 1,000 patients is an estimate of the number of high-utilizer patients who would be required to justify a cost savings, and ultimately a return on investment. We calculated that at least 300 high-utilizer patients would need to be included in our IBD SMH to show a reduction in health care utilization and total cost of care. Therefore, if we assume that approximately 30% of any chronic disease population drives the majority of cost and represents the highest utilizers, we estimated that at least 1,000 patients should be covered by a single insurer.

For development of an SMH, there are two approaches that may be taken: Design the medical home for the entire Health Plan’s population of patients with the disease of interest, or focus only on the high-utilizing, most expensive patients. The latter will include a more complex and challenging cohort of patients, but likely will provide the opportunity to show a reduction in utilization and total cost of care than a broader all-comers population approach.



Physician champions

A successful SMH requires a physician (or health care provider) champion. IBD care within the SMH is unique and distinct from gastroenterologists’ classic training and specialty care. In addition to addressing the biologic disease, the emphasis is on whole-patient care: preventive care, behavioral medicine, socioeconomic considerations of the patient, and provision of care for nongastrointestinal symptoms and diseases. In an SMH, the specialist must be willing to incorporate and address all facets of health care to improve patient outcomes.

Goals and measures of success

To ensure successful deployment of an SMH, it is important to establish shared payer–provider goals and metrics during the construction phase of the medical home. These goals should include an enrollment target number for each year, quality improvement metrics, patient experience outcomes, and metrics for a reduction in health care utilization and total cost of care. Examples of our IBD SMH year 1 and year 2 goals are outlined in Supplementary Table 1 (at http://dx.doi.org/10.1016/j.cgh.2017.05.026). In the first year of our IBD SMH, we were able to achieve our goals, and publication of our results is forthcoming. We have enrolled more than 325 patients, retained 90%, reduced emergency room visits and hospitalizations by 50%, and significantly improved quality of life. Most of our patients have been assigned an HP coach and use the electronic medical portal to communicate with the medical home. Our patient satisfaction for physician communication was 99%.

 

 

Key components of the IBD medical home

Based on our experience, we believe the following are key components of a successful IBD SMH: 1) team-based care with physician extenders, nurse coordinators, schedulers, social workers, and dietitians as essential members of the IBD SMH; 2) effective care coordination to reduce barriers to comprehensive biopsychosocial care; 3) tracking of process and outcome metrics of interest; 4) appropriate use of technology to enhance clinical care; and 5) care access (e.g., open-access appointments), after-hours care, and follow-up care after emergency room visits and hospitalizations (Table 1).

Essential components of an inflammatory bowel disease specialty medical home
There is not a one-size-fits-all SMH model given the range of different subspecialty practices. The appropriate dose for each specific setting may vary, and we recommend an iterative deployment process starting with a few case studies and then sequentially rolling out to a larger-scale clinical sample. The goal of the initial SMH is to show feasibility and understand which components are most critical for successful implementation.

Although the eventual goal of an IBD SMH is to consolidate health care for all IBD patients, the initial launch stages are more likely to succeed if the SMH focuses on the subgroup of IBD patients who use health care excessively, often in an unplanned fashion (e.g., emergency department visits or hospitalizations). In conjunction with a payer, it is easy to identify the most costly IBD patients in a cohort. For example, for initial enrollment, the UPMC IBD SMH selected patients between the ages of 18 and 55 years, with confirmed Crohn’s disease or ulcerative colitis, and evidence that IBD was a primary driver of patients’ health care utilization; the latter was defined if the majority of health care expenditures in the prior year was related to IBD (as judged by International Classification of Diseases, 9th and 10th revisions, primary and secondary diagnoses).
 

Team-based care

A central component to our IBD SMH was the creation of an integrated team. Supplementary Table 2 (at http://dx.doi.org/10.1016/j.cgh.2017.05.026) describes various positions that are vital for a successful SMH. For a team approach to be most effective, there needs to be clear definitions or roles and role overlaps so that team members can work as a cohesive, organized, and efficient unit. Physician extenders are critical to the model’s success and are trained to make routine IBD care decisions, provide basic primary care, and coordinate care with the gastroenterologist to meet patient needs. The staff-to-patient ratio requirements may vary from region to region and from SMH to SMH. The nurse coordinators and physician extenders assume the burden of day-to-day patient care, and are supervised by the gastroenterologist and psychiatrist. In our UPMC IBD SMH, the ratio of one nurse coordinator and one certified nurse practitioner per 500 patients is sufficient. In addition, one social worker, one dietitian, one scheduler, one gastroenterologist, and one psychiatrist per 1,000 patients is our current model. To date, we have enrolled more than 500 patients, and through funding from our UPMC HP, we have just hired our second nurse coordinator and second nurse practitioner in anticipation of 1,000 patients by year 4.

Figure 1
In an ideal team model, all staff, both behavioral and medical, are trained in basic behavioral assessment and interventions, motivational interviewing, and disease self-management techniques so that the behavioral health specialist can be considered a second-line provider or a consultant to the gastroenterologist for the most complex psychiatric patients. Figure 1 shows a typical patient’s trajectory through the IBD SMH.
 

Care coordination and incorporation of technology

The team composition is organized to provide tiered care for optimal efficiency. For such a stepped care model to be effective and scalable, two components are essential. The first component is a care coordination system that allows for the reliable classification of the biological, psychological, social, and health systems barriers faced by patients. To this end, our SMH developed an IBD-specific complexity grid (Supplementary Table 3; at http://dx.doi.org/10.1016/j.cgh.2017.05.026) that was derived from a primary care model.12 The second component is the use of technology-enhanced care to scale delivery of services in a population health model. Examples of technology in our SMH include the use of telemedicine/telepsychiatry by secure video, health coach virtual visits, remote monitoring, and provider-assisted behavioral interventions that patients can access on their smart phones.

New payment models for specialty medical homes

The SMH transitions away from relative value unit–based reimbursement and toward a value-based paradigm. In the SMH, the gastroenterologist serves as the principal medical provider for the IBD patient. Both providers and payers will be able to refer patients to the SMH. Data on quality metrics will be tracked and physician extenders and nurse coordinators will help ensure that goals are met. Quality improvement, preventive medicine, telemedicine, and point-of-contact mental health care will replace the volume-based relative value unit system.

 

 

Alternative payment models will be required to support the SMH. Because of the novel nature of the SMH, the optimal payment model has yet to be determined, but probably will include either a shared savings or global cap approach, with an emphasis on the total cost of care reduction. This means that the specialist in the SMH must be aware of all care, and the cost of care, that the patient receives. Biologics and other IBD therapy costs are high and will continue to increase. The sustainable model must be sufficiently supple to not disincentivize the provider to use proven and effective, albeit expensive, therapy for patients who need it most. A close working relationship between the SMH providers and the health plan chief pharmacy officer will be essential. We expect that appropriate use of medications will lead to a medical cost offset with improved IBD outcomes, a reduction in health care utilization, and optimized work and life productivity.
 

Conclusions

In new models of care, specialty providers partner with payers in a patient-centered system to provide principal care for patients with chronic diseases, including IBD, in an effort to reduce costs and provide efficient, high-quality care. These models will require close collaborations with payers, a sufficiently large patient population, a physician champion, and a multidisciplinary staff targeting various aspects of health care. Successful implementation of such models will help reduce costs of care while improving the patient-centered experience and outcomes.
