The impact on ambulance mobilisations of an increasing age profile of telecare service users receiving advanced proactive, personalised telecare in Spain - a longitudinal study 2014-2018.

Introduction: Spain is one of the leading countries in the application of proactive and personalised telecare to help support frail and vulnerable service users to live independently in their own homes for longer*. Concern was however noted regarding potential impacts on ambulance mobilisations as time in the service, and mean age at cessation, increased by 1.3 years. Aims, Objectives, Theory and Methods: The purpose of this study was to investigate these impacts. A longitudinal study of a telecare service user population in Spain (n=202.1k to 247.9k) was undertaken using anonymised operational data collected in the delivery of proactive and personalised telecare services by Televida Servicios Sociosanitarios over the period 2014-18. The population was subject to change over time as new service users became eligible to register for the service, and others ceased the service. Each of these factors were also studied to assess potential confounding or covariate factors in the population also influencing the mobilisation of ambulances. Key Findings: For the studied population, ambulance mobilisation on a per-person/per-annum (pp/pa) basis reduced over the period despite the increasing age profile at cessation and with the characteristics of the population at registration remaining otherwise similar over the period. Overall mobilisations reduced by 27.9% (0.665 to 0.479 pp/pa) over the period whilst for ambulances there was a reduction of 33.3% (0.461 to 0.307 pp/pa). There were also smaller reductions in the number for family and state security mobilisations. The study identified the positive correlation coefficient between ambulance mobilisations and service user's dependency levels, and marginal negative correlation in older age bands. We are aware of no other studies which have investigated the impact on ambulance mobilisations of advanced proactive telecare and the increasing age of the services users supported to continue living independently. We believe this paper, therefore, contributes new insight which extends the existing research literature. Conclusions: The increasing age at cessation has not correlated with an increased proportion of higher dependency service users. The share of those over 85 years in the high dependency level decreased. This indicates that the changes in the telecare service contributing to increased time living independently may also have helped service users remain in lower risk bands. Limitations: There is a risk that use of mean annual measures may obscure important variations within the data. Changes in levels of proactivity, personalisation and increased use of sophisticated monitoring sensors of the telecare services are not the subject of this paper, but addressed in part in allied research.
