Introduction of Chronic Diseases
According to the Center for Medicare and Medicaid Services (CMS), the United States spent $2.7 trillion dollars on healthcare in 2011, which made up 17.9% of the GDP (Squires, 2012). One of the most pressing issues affecting a high amount of Americans while contributing a significant amount to health expenditures are chronic conditions, which account for more than 75% of healthcare expenditures at approximately $2.025 trillion. Chronic conditions are prolonged in duration, do not resolve spontaneously, and are rarely cured completely (CDC, 2013). All chronic illnesses have the potential to limit the functional status, productivity, and quality of life of those affected (IOM, 2012). According to The Center for Disease Control and Prevention (CDC), 133 million Americans suffer from chronic conditions, which cause 7 out of 10 deaths each year in the United States (CDC, 2013). Chronic disease accounts for more than 75% of healthcare expenditures, which is approximately $2.025 trillion. TheInstitute of Medicine (IOM) asserts, “All chronic illnesses hold the potential to worsen the overall health of our nation by limiting an individual’s capacity to live well,” and has defined a list of nine chronic conditions that affect the most people and dominate health expenditures in the United States (IOM, 2012).
The chronic condition from which the fourth-most Americans suffer, Type II Diabetes Mellitus (T2D), could in many cases have been prevented through a change in the delivery of care (Table 1). T2D is the sixth leading cause of death in the United States (2010 National, 2010). Many of the known risk factors have implications on the healthcare system. For example, as of 2007, the U.S. has spent approximately $174 billion on care related to T2D (AHRQ, 2012).
An Overview of Type II Diabetes Mellitus
Approximately 8.3% of the United States population is affected by diabetes. There are 25.8 million people in the United States with diabetes, 18.8 million of which who have been diagnosed with diabetes, and an estimated 7.0 million people who have diabetes but have not been diagnosed (National Diabetes, 2011). Diabetes is a chronic disease caused by the body’s inability to make or process insulin, which is required to convert glucose into energy (Mayo Clinic, 2003). Diabetes Mellitus Type I, occurs when the pancreas is unable to produce insulin. This is typically a congenital disease, and it can be managed through insulin injections (Mayo Clinic, 2003).
Insulin-resistant diabetes mellitus, commonly referred to as T2D, is the most common form of diabetes, affecting 95% of people with diabetes (American Diabetes Association, 2014). In T2D, the fat, liver, and muscles of the body are unable to properly respond to insulin, which allows high levels of sugar to build up in the blood, resulting in hyperglycemia (NIH, 2013). Early symptoms of T2D are fatigue, hunger, increased thirst, increased urination, and bladder, kidney, skin, or other infections that are more frequent or take longer to heal (NIH, 2013). There is currently no cure for T2D. However, treatments include blood sugar monitoring, healthy eating, regular exercise, and some forms of diabetes medication or insulin therapy (Mayo Clinic, 2013).
There are many risk factors associated with T2D, some of which include: obesity, hypertension, a family history of diabetes, a prior history of gestational diabetes, high cholesterol levels, or physical inactivity (CDC, 2013). These risk factors are more commonly found in older populations as one’s health status continues to decline with age, leading to a higher rate of risk factors of T2D. Figure 1A demonstrates the positive correlation between T2D incidence and age, demonstrating that older age categories had higher rates of incidence of T2D. Due to the current declining health of the population of a whole in the United States, including higher rates of obesity and related co-morbidities, general incidence of T2D has also increased (Fig 1B). The risk factors mentioned above, such as being overweight or obese, having high blood pressure, and abnormal cholesterol levels are three factors that are most prevalent in African American, American Indian, Asian American, Pacific Islander, andHispanic American/Latino communities. Thus, many diagnosed with T2D in the United States fall into the aforementioned ethnic communities, which highlights the possible issue of health disparities. Figure 1C demonstrates the higher rate of diagnosed diabetes in groups of African Americans and Asians than in groups of Caucasians. Moreover, studies have shown that minorities for the most part have high complication rates when it comes to T2D, indicating possible discrepancies in treatment and management (Fig 3). Furthermore, the rate of diabetic end stage renal disease (ESRD) is 2.6 times higher among African Americans than Caucasians, which may be attributed to the interaction between hypertension and T2D (AHRQ, 2013).
Best Practices for Management of Type II Diabetes
In order to facilitate optimal outcomes in diabetes management, several guidelines have been established outlining best practices. These best practices, once fully explored, can eventually be implemented as a standard process of managing chronic disease in an effort to increase the standardized, evidence-based practice that can lead to better health outcomes overall. The following are best practices in the clinical aspect of T2D care and the standards of self-management of diabetes.
The American Diabetes Association has created a framework of clinical T2D management. The first aspect of clinical care is classifying the types of diabetes and standardizing the measures of diabetes diagnosis and pre-diabetes diagnosis. In 2009, the International Expert Committee recommended the use of the A1C test to diagnose diabetes, with the threshold at greater than 6.5% (National Diabetes, 2011). This would also be used to determine the individuals who are between a healthy glucose level percentage and 6.5%, who would be defined as having impaired glucose intolerance. The next aspect of diabetes management would be testing for diabetes in asymptomatic patients. As previously mentioned, a lack of testing in a preventative capacity of testing to treat in the early stages can be hindered by a lack of PCP usage. Best practices suggest testing the A1C levels of adults of any age who are overweight, obese, or have other risk factors for diabetes, and repeating the tests every threeyears. The same A1C test that is used for diagnosis should be used for screening. Due to the long presymptomatic phase of T2D, as well as the increasing prevalence among populations, screening is recommended for adults with the risk factors of diabetes and children and adolescents who are overweight so that efforts can be taken to delay and prevent the formation of T2D. Best practices in preventing and delaying diabetes include losing 7% of body weight, increasing physical activity, and annual monitoring (National Diabetes, 2011).
Diabetes care must first begin with the initial evaluation of the type of diabetes as well as the risk factors that could lead to complications. A comprehensive, patient-centered plan must be established for the individual patient based on their medical condition to facilitate the disease management. This management would be assisted by a variety of health providers who would ideally work with this individualized plan. The next aspect of diabetes management would be glycemic control, which would require the assessment of glycemic control through regular glucose monitoring, and A1C tests that are administered consistently over the individually recommended intervals. Lowering the A1C below 7% has been shown to reduce complications associated with diabetes. However, the healthcare provider may recommend different levels for different patients. Metformin is the recommended pharmacological agent for T2D, while insulin therapy is usually used. Individualized medical nutrition therapy (MNT)should also be developed, with the mix of carbohydrate, protein, and fat contents adjusted to meet the metabolic goals and individual needs of the patient.
It is recommended that individuals with diabetes receive standardized diabetes self-management support (DSMS) as well as diabetes self-management education (DSME), which are ongoing processes of facilitating the knowledge, skill, and ability necessary for diabetes self-care (National Diabetes, 2011). There are ten national standards for DSME (Table 2). Additionally, it is recommended that the individuals receive psychosocial assessment and care to determine the root cause of unhealthy behaviors, and that the patient increase physical activity. The American Diabetes Association has also developed standards for preventing further complications from diabetes.
This system would be beneficial to chronic disease management, especially in managing T2D. Because T2D requires constant coordinated care, the transparency of information and coordination of the ACO could address these needs to ensure that the proper tests are being done at the proper time. Furthermore, because ACOs are incentivized to keep the patient population healthy, they would be incentivized to follow the recommended process of performing the tests to maintain better health and manage T2D. Additionally, because many of these ACOs will be formed through the MSSP, many people suffering with T2D who are in the 65 and up high-risk category would be able to use these ACO models to help manage their diabetes through Medicare. The ACO model would address the issues of delivery of coordinated and preventative care through information transparency and data sharing among providers, thus also increasing patient centeredness. It is to the advantage of the ACO to maintain the health of thepatient, so they are incentivized to carefully explain to their patients how to manage diabetes and to follow up on their patients regularly.
The current ACO model does not address the root causes of T2D. However, if the ACO models are successfully integrated into the healthcare system and are able to revolutionize care coordination, other healthcare providers will form similar organizations that might be able to serve all ages throughout the continuum of care. The consistent and preventative care from these visits may help people become more aware of the causes of diabetes, so they can attempt to make better, more informed health decisions in an effort of avoiding chronic disease in the future. While the social determinants of health will still be barriers, the consistent reminders and monitoring of the ACO might decrease the incidence rates of T2D in the future.
Measuring the Effectiveness of the ACOs on Type II Diabetes Management
The effect of the ACOs on T2D management can be measured in many ways. Figure 3demonstrates improvement in the short term because it measures the percentage of people in each ethnic/racial group that received the entire defined process of recommended tests. Those specific tests are recommended to reduce the likelihood of poor outcomes, such as heart attack or stroke, so measuring the percentage of patients in the ACO that receive all of the recommended tests would be a good indicator of improved quality in diabetes management. While simply the number of adults who received all tests could show the effectiveness of the ACOs on diabetes management, comparing the different ethnicities/races, education level, and age level who received all tests could further evaluate if and how much the ACO is standardizing care by consistently administering the tests to all patients, regardless of race, education level, and age. These numbers could then all be compared to the most recent qualitybenchmark measurement as described by the National Healthcare Quality Report.
An example of an ACO model developed to manage chronic disease that could be especially applied to management of T2D is the Quality Blue Model developed by Blue Cross Blue Shield of Louisiana (BCBSLA). BCBSLA partners with various patient centered medical homes to monitor the health maintenance of at risk patients. Through a setup using health information technology and a structured care team, physicians are able to more closely and consistently monitor high risk patients, while receiving monthly reimbursement management fees based on meeting certain quality benchmarks (BCBSLA, 2013). This model incentivizes primary care teams to maintain the health of at-risk patients, performing the standardized tests and best practices to manage chronic disease, such as T2D.
In the long term, the trend of the amount of diabetic patients who have had severe heart attacks or strokes can be evaluated. If the diabetes management has been effective, the likelihood of severe heart attacks or strokes, although not eliminated, can be reduced. A significant reduction would indicate progress in diabetes management. The development of T2D as a whole can be evaluated in the long term if two different groups of kids from the same area and socioeconomic status could be evaluated through their lifetime, with one group using an ACO, and one group using the current system of care. If the group who used an ACO had significantly better health outcomes, and other variables had been standardized, it would be evident that preventative care had an influence on the long-term health outcomes. An analysis of various ACOs created through the MSSP program found that ACOs reduced spending by 2.5%, reduced inpatient admissions 2.5%, reduced readmissions 9.7%, and reduced potentiallypreventable initial admissions by 13.2%, while increasing outpatient services by 7.4% (Early ACOs, 2014).
