In conclusion, there have been numerous attempts reported in the literature to develop services that focus more on optimising function rather than fostering dependency among older people supported to remain in their home. Our study utilised the concepts previously described, together with a philosophy of person-centred care. Our primary purpose was to assess the impact of TARGET on HRQoL among community-dwelling older people referred for homecare, and the results clearly show the success of TARGET in facilitating identification of a goal by older people––84% of participants in the intervention group developed a goal during assessment. An important result was the significant effect that use of the tool had on HRQoL among the intervention group. Two potential mechanisms for this change were explored (regular formalised review and an increase in individually tailored support activities). However, the absence of implementation of regular reviews across all participants in the intervention group suggests that this is not the primary mechanism for maximising HRQoL. In contrast, the significantly higher number of individualised support plans generated following use of TARGET appears to have been instrumental in delivering services that contributed to increases in HRQoL. The study findings contribute to greater understanding of factors necessary to implement improvements in the services for older people in the home.
