Non-regular use of hearing aids
A meta-analysis showed that hearing aids (HAs) had a medium-to-large effect on health-related quality of life (Chisolm et al. 2007). Despite this, a recent study in National Health Service (NHS) in the United Kingdom showed that 29% of people (293/1021) do not use their NHS HAs regularly (i.e., use less than 4 hours per day) (Aazh et al. 2015). The non-regular use was 39.5% for new patients (Aazh et al. 2015). Previous studies in NHS also reported 43% to 45% for non-regular use (Stephens 2002; Davis et al. 2007).
In NHS, the choice of HAs is limited. In other countries, patients may have the choice of several HA makes. Despite this, non-regular use in NHS is comparable to that found in other countries: 27% and 58% in two Australian studies (Hickson et al. 2010; Stark & Hickson 2004), 42% in Finland (Vuorialho et al. 2006), 13% to 31% in four studies conducted in the USA (Kochkin 2010; Takahashi et al. 2007; Williams et al. 2009), and 25% in Switzerland (Bertoli et al. 2009). For further detail see Aazh et al (2015).
The exact reasons for non-regular use of hearing aids is not fully understood (Aazh 2016). However, it seems that the discrepancy between patients’ expectations (e.g., full restoration of hearing, a “cure”) and what a hearing aid can offer may contribute to the ambivalence experienced by some (Boothroyd 2007). A phenomenological study suggested that some patients do not regard HAs as acceptable solution but agree to get them mainly to please their partner or family members (Claesen & Pryce 2012). Two systematic reviews concluded that stigma of deafness and self-reported hearing difficulties are the main barriers to HA use (Knudsen et al. 2010; Jenstad & Moon 2011).
The protocol and clinical manual of Motivational Interviewing (MI) for hearing aid use taught in this masterclass synthesises the knowledge gained through decades of research in the field of rehabilitative audiology and amplification with relevant concepts of modern psychology and behaviour change. This protocol, which developed by Dr. Hashir Aazh and his team over the years, describes an evidence-based method which is feasible to be delivered in day-to-day outpatient audiology clinics and fine tuned base on in-depth evaluation and qualitative assessment of patients’ feedback and the outcome of clinical research.
