Primary healthcare services have changed from face-to-face to tele-consults during the two COVID-19 years. Researchers examined trends before and during the COVID-19 pandemic years based on groups of professionals, patient ages, and the associations with the diagnostic registry. Researchers analyzed proportions for both periods, and ratios of the type of consults in 2017–2019 and 2020–2021 were calculated. The COVID-19 period was examined using monthly linear time trends. The results showed that consults in 2020–2021 increased by 24%. General practitioners saw significant falls in face-to-face consults compared with 2017–2019 (ratio 0.44; 95% CI: 0.44 to 0.45), but the increase was not proportional across age groups; patients aged 15–44 years had 45.8% more tele-consults, and those aged >74 years had 18.2% more. Trends in linear regression models of face-to-face consults with general practitioners and monthly diagnostic activity were positive, while the tele-consult trend was inverse to the trend of the diagnostic registry and face-to-face consults. Tele-consults did not resolve the increased demand for primary healthcare services caused by COVID-19. General practitioners, nurses and primary healthcare professionals require better-adapted tele-consult tools for an effective diagnostic registry to maintain equity of access and answer older patients’ needs and priorities in primary healthcare.
