In Spain, public health services are managed by the National Health Service and are based on the right of every person to be in good health, regardless of their economic or work situations.As people age, they tend to increase their use of health services and thus meet the professionals who assist them (Nie et al., 2008).The ageing process is evident in Spain; the latest census (Real Decreto 1039, 2017) indicated that 8,700,000 people are already over 65 years old, comprising approximately 18.7% of the total population (Instituto Nacional de Estadística, 2017).
