While the prevalence of having multiple chronic conditions, or multimorbidity, increases with age, the numbers of people living with multimorbidity of all ages is increasing.1 Forty-eight percent of older adults have 3 or more chronic conditions.2 Many people living with multiple chronic conditions are less than 60 years of age. 3,4 In younger populations, 35 percent of disabled adults have 3 or more chronic conditions.5 Among children, where the definition of a chronic condition is less clear, prevalence estimates range from less than 1 percent up to 44 percent of children living with multiple chronic conditions.6 The presence of multiple chronic conditions is especially important when each condition may influence the care of the other condition(s) through limitations of life expectancy, interactions between drug therapies, and/or direct contraindications to therapy for one condition by other conditions.7-10
The Role of Guidelines:
Our existing evidence base often struggles to adequately inform patient-centered care for people with multiple chronic conditions, or multimorbidity.11 Guidelines focused on specific individual conditions may not be applicable to people with multiple chronic conditions.11-14 Primary studies often:
We can’t forget though, that as the Institute of Medicine noted,
“Clinical practice guidelines are statements that include recommendations intended to optimize patient care that are informed by a systematic review of evidence and an assessment of the benefits and harms of alternative care options. Rather than dictating a one-size-fits-all approach to patient care, clinical practice guidelines offer an evaluation of the quality of the relevant literature and an assessment of the likely benefits and harms of a particular treatment. This information enables providers to proceed accordingly, selecting the best care for a unique patient based on his or her preferences.”15
This definition, and goal, is exactly what is needed for people with multiple chronic conditions. Despite this ideal, developing guidelines that inform person-centered care for people with multiple chronic conditions is challenging, and the relevance of these guidelines is limited.11-14
These are exciting times for the realm of multimorbidity in guidelines. Efforts to address this growing population are underway around the world. There is not a universal answer on how best to address people with multiple chronic conditions in guidelines; rather it depends on the specific question being addressed.
How might guidelines increase their relevance to the care of people living with multiple chronic conditions? A stakeholder informed framework was developed that illustrates several key frames that can be used to inform trustworthy guidelines:16
The National Institute for Health and Care Excellence in the United Kingdom recently published a guideline on Multimorbidity: Clinical Assessment and Management. The NICE guideline covers optimizing care for adults with multimorbidity through several key recommendations:
The guideline addresses several key issues that matter to people with multiple chronic conditions, including reducing treatment burden (polypharmacy and multiple appointments). Second, the approach to care recommended for this population specifically focuses on shared decision making based on what is important to the person.
This is just a snippet of all the innovative work being done to address the exciting opportunity to meet the needs of people living with multimorbidity through evidence-based medicine and person-centered care. These concepts are in no way contradictory to each other – our challenge, and work ahead, is to make sure both are realities for people living with multimorbidity.
