An expert explains how to grow an underutilized sleep medicine service.
Oral appliance (OA) therapy can be as effective as CPAP for the treatment of mild to moderate obstructive sleep apnea (OSA) and can even benefit some patients with severe OSA. Although data is limited, adherence to OA therapy appears to exceed adherence to PAP, and compared to PAP, patients prefer oral appliances by a margin of 2:1.1 Yet despite these many strengths, OA therapy is underutilized.
Many factors impact the uptake of OA therapy, including scope of practice boundaries, a gross shortage of trained dental sleep providers, and a less mature evidence base relative to PAP. And to be clear, OA therapy should not and will not replace PAP. Even so, in my view, the single greatest barrier to more widespread adoption is a lack of perceived value from sleep medicine stakeholders.
I have coined the term “value-based sleep” to highlight the need for greater emphasis on health economic outcomes in our field and to increase focus on those that matter most to our constituents.2 Recently, I have begun to apply these same concepts to help grow dental sleep medicine and benefit patients unable to tolerate PAP. Here, I introduce the tenets of value-based dental sleep medicine.
Value Is in the Eye of the Beholder
Unlike sleep medicine professionals—who understand the many benefits of sleep and reasons to treat sleep disorders—most people only appreciate sleep as means to an end. That is, stakeholders care about sleep only to the extent it helps them achieve their non-sleep goals. For example, patients value sleep to the extent it increases their quality of life. To provide and demonstrate value, dental sleep medicine specialists must understand clearly the values of multiple constituents (see Table 1).
Three Steps to Grow the Value of Dental Sleep Medicine
1. Adopt a patient-centered approach.
For most patients, sleep is an input, not an output. In other words, patients want to live longer, healthier, happier lives. They want more energy for recreation, enhanced cognitive function for work, and greater social connection. Yet too few dental sleep medicine specialists know how to assess these kinds of patient-centered outcomes. Instead, the clinical and research literature has focused almost entirely on the apnea-hypopnea index (AHI). And of course, no patient cares about the AHI!
From a research perspective, more studies are needed to identify the impact of OA therapy on quality of life, neurocognitive, and cardiovascular and cerebrovascular disease risk outcomes—all of which matter greatly to OSA patients.
2. Increase focus on economic outcomes.
In a recent review of the economic impact of OSA treatments, we found only one empirical study evaluating the effect of OA on monetized economic outcomes.3 Quinnel and colleagues found that relative to no treatment, three types of OAs (self-molded, semi-custom, and fully custom) were cost-effective within a 6-week followup period.4 These promising results warrant confirmation within diverse samples of OSA patients and with longer followup periods. Even so, this finding can be viewed optimistically and suggests that OA therapy can provide a favorable economic return.
To grow the field and increase access to dental sleep medicine care, more health economic studies are needed. To increase market access, payers will need to be convinced that OA therapy can provide an important return on investment, relative to PAP and other available treatment options.
3. Develop a value-based lexicon.
For dental sleep medicine to grow, it must develop language that speaks directly to the needs and wants of patients, constituents, and partners—in terms that matter to them. This means first developing an internal mindset of “what’s in it for them?” and second, refining the external language and communication skills to highlight this value.
For most private practice dental sleep specialists, this includes at minimum developing language for patients, referring sleep centers or other medical specialists who refer, and insurance payers. In terms of leadership of the field, expanding the scientific evidence base and clarifying the role of dental sleep medicine are paramount.
We live in a healthcare climate of increasing costs on the one hand and limited resources on the other. As a result, it is more important than ever for dental sleep medicine specialists to define, demonstrate, and maximize their substantial value. This will require intense focus on the outcomes that matter to diverse stakeholders—outcomes including quality of life and reduced healthcare spend. The good news is that dental sleep medicine is poised for major growth. Thus, the time to incorporate a value-based sleep perspective into other strategic initiatives is now. Adopt a value-based dental sleep approach and survive, thrive, and grow.
