The fourth and final panel installment of this series continues to examine why audiologists need not be so fearful about the possibility of a future rife with OTC devices. The data pretty clearly shows that there will be a continued demand from consumers for customized hearing care delivered by audiologists and other licensed professionals.
An important model to study on a national scale is the hearing aid market of Japan, where OTC devices are readily available in retail stores, on the Internet, and via mail order (Hougaard et al., 2013).
In one particular study (Hougaard et al., 2013), hearing aid uptake in Japan was the lowest of all developed countries, at 14%, compared to an average of 35% in France, Germany, the United Kingdom, and the United States. Additionally, only 39% of hearing aid users were satisfied with their devices, compared to approximately 80% in the other developed countries.
However, who is to say what the results will be in a model that offers both conventional and OTC hearing aids? Could these OTC users add to the ones that are already using the traditional model?
Cultural difference between West and East also play a confounding role in trying to analyze these data, as views on aging and disability are quite different.
As the patients will ultimately decide if they want to engage with an OTC device at some point along their journey, it is essential to consider the evidence about perceptions of OTCs. Here’s what we know so far:
Patient Perception Study #1
A recent survey (Plotnick & Dybala, 2017) of 809 adults was conducted to assess their opinion of a potential OTC hearing aid. The sample was adults aged 50 years and older, geographically and socioeconomically diverse, and most had little experience with hearing aids; this is thought to be emblematic of the market interested in low cost OTC hearing devices.
The results indicated that 93.8% of survey respondents considered the involvement of a hearing care professional in the selection, fitting, and programming of a hearing aid to be either very important or absolutely important. Interestingly, 95.3% of respondents were only willing to spend $200 or less on an OTC hearing aid (Plotnick & Dybala, 2017).
On the whole, consumers understand the potential benefits of direct-to-consumer hearing aids, but they also express reservations and a preference for the involvement of an audiologist (Kochkin, 2014; Chandra & Searchfield, 2016; Plotnick & Dybala, 2017).
Patient Perception Study #2
In a semi-structured interview survey of 18 older adults (Chandra & Searchfield, 2016), the perception of internet-purchased HAs is mixed. Most participants were unaware that hearing aids can be purchased online. When the process was described to them, several themes emerged from participants’ responses. They recognized potential benefits of purchasing aids online, such as perceived lower cost and increased convenience and physical accessibility.
There were reservations among participants about purchasing aids online, though, including whether and how clinical procedures would be performed in the assessment and fitting of hearing aids; procedures noted were hearing evaluation, fine-tuning of hearing aids, and physical ear mold modifications.
Participants also conveyed a general distrust of online retailers, which included a lack of trustworthiness, a lack of trust in the brand of hearing aid, and a fear of scammers. Several participants stated that they preferred involvement of an experienced professional in the hearing aid fitting process, and they considered this type of expert advice and support to not be available in an online retail framework (Chandra & Searchfield, 2016).
Patient Perception Study #3
Similar results were found in a survey asking 80 older adults about their perception of a hearing aid which is self-fit without the involvement of an audiologist (Convery et al., 2011). Participants noted potential benefits such as increased convenience and the ability to self-adjust the device, however they also expressed a preference for professional guidance through the fitting process.
About half of the participants responded affirmatively to all three of the following: that a self-fitting aid was a good idea, that it would be of personal benefit, and that it could be managed independently by the user (Convery et al., 2011).
The way I interpret these data is that OTC devices will produce mixed results, helping a sizeable proportion of customers but leaving many others unsatisfied. From the relatively limited evidence that exists, the proportion of successful OTC consumers, characterized as those that are at least somewhat satisfied or have at least moderate improvement in QOL, ranges from 39-58% (Hougaard, 2013; Kochkin, 2014; Convery et al., 2015; Convery et al., 2016; Tedeschi & Kihm, 2016; Humes et al., 2017).
For individuals that are successful with the devices, OTCs represent a high value product that may improve hearing, reduce the handicap associated with hearing loss, and increase quality of life (PCAST, 2015). This represents a public health boon that audiologists should support. However, although OTCs provide decent benefit and great value, an overwhelming majority of patients have reservations about self-care and still want a professional to be involved in the process (Convery et al., 2011; Kochkin, 2014; Chandra & Searchfield, 2016; Plotnick & Dybala, 2017).
OTCs may be a reasonable self-treatment option, used in conjunction with professional collaboration, for the vast majority of people with mild-to-moderate hearing loss who do not seek treatment from the traditional hearing healthcare delivery model (see below).
Although they have the potential to make a positive public health impact, OTC devices have significant weaknesses and don’t fix non-cost-related reasons why people don’t wear hearing aids. The legislation and OTC devices themselves fail to overcome the stigma associated with wearing hearing aids or the difficulties that individuals in the target market have with dexterity problems, among other shortcomings. The focus on OTC devices fails to address the importance of family and community support networks and self-management of hearing loss in difficult listening situations (Hogan et al., 2015).
If I haven’t lost you in that too-long look at OTC studies, congratulations to you and for your reward, here is a photo of a turtle that chose fight:
In the fight-or-flight decision over OTC hearing aids, the obvious choice is fight. Ironically, I don’t mean fight the legislation or fight change in general. I mean fight the urge to give up.
Anyone suggesting that OTCs will take down our profession is implicitly saying that our knowledge and skills can be replaced by a device and a CVS clerk. To that I say: come at me, bro!
I find that sentiment to be utterly ridiculous, and the evidence clearly suggests that patients want a professional’s involvement in the hearing aid process. Future-thinking audiologists should see OTCs as an opportunity, and they should be prepared to augment the hearing healthcare of both satisfied and unsatisfied OTC users. For patients who are experiencing success with OTC devices, audiologists have a role in objectively documenting their status and adding value via counseling, real ear measures, speech in noise testing, and validation questionnaires.
For OTC users who are not satisfied with their devices, the audiologist has a role in improving their performance and introducing them to services and devices that may provide more benefit including aural rehabilitation, hearing assistive technologies, and traditional hearing aids.
In a more general sense, the future will bring more change to our profession, not less. If we think every threat will end us, and our strategy is to be discouraged and run away, then this will become a self-fulfilling prophecy. One example of this I have seen is people explicitly discouraging potential audiology students from joining the profession. I’m all for giving people the whole truth and letting them decide for themselves, but in my opinion this recommendation and this attitude in general, is a much, much, much greater threat to the profession than OTC devices.
In conclusion, the OTC conversation has stirred the pot tremendously, but I hope the information presented in this series will calm some nerves. In my opinion OTCs will not trivialize our profession, and they will help (to some degree) millions of people who have previously not engaged with hearing healthcare. As audiologists, our core mission is to help people communicate better, not to help them communicate better with hearing aids, on our terms.
We should be excited to help people hear better regardless of whether the technology we employ is via an app, OTC, hearing aid, cochlear implant, or even hair cell regeneration.
