The general relationship between treatment and response is illustrated with reference to the response of elderly people to rehabilitation treatment after a hearing aid has been prescribed. The evidence of the effects of treatment is reviewed and a tentative empirical relationship is proposed between treatment input (therapist time) and effect (hours of use of the hearing aids). This illustrates a rapid improvement in the effect of treatment for up to about one hour of therapist time but very little improvement with increasing input thereafter. The resource implications are discussed and it is concluded that an input of an average of one hour of follow-up would be a very worthwhile investment and should be a priority for expenditure by health authorities.
通过参考老年人在佩戴助听器后接受康复治疗的反应，说明了治疗与反应之间的一般关系。回顾了治疗效果的证据，并提出了治疗投入（治疗师时间）与效果（助听器使用时长）之间的初步经验关系。这表明，在治疗师投入约一小时的时间内，治疗效果会迅速改善，但此后随着投入的增加，改善甚微。文中讨论了资源影响，并得出结论：平均投入一小时的随访是一项非常值得的投资，应成为卫生当局支出的优先事项。
