Change of primary health care service provider model in Vantaa: the impact on mortality and causes of death among older adults – a register-based follow-up study

TL;DR

A study in Vantaa, Finland, found that changing the primary health care model improved mortality rates among older adults.

Contribution

This paper evaluates the impact of a specific PHC model change on mortality and causes of death in older adults using register-based data.

Findings

The SMR decreased after transitioning to the restricted-list GP model, with fewer excess deaths by 2018.

Circulatory disease deaths decreased, while cancer and dementia-related deaths increased over time.

The restricted-list GP model was associated with improved mortality outcomes in older adults.

Abstract

Access to primary health care (PHC) has declined in Finland in recent years. To address this, the city of Vantaa, Finland, transitioned from a named general practitioner (GP) model to a restricted-list GP model in 2011 to increase access to named GPs for the most vulnerable population. This study evaluates the impact of this model change on mortality rates and causes of death among older adults.

This register-based follow-up study was conducted in Vantaa, Finland, using data from the electronic health records. The study included all patient contacts aged 75 and older between 1 September 2004 and 31 August 2018. The primary outcome was the Standardised Mortality Ratio (SMR). We calculated excess deaths and examined cause-specific mortality trends before and after the restricted-list GP model implementation.

During the study period, 32,034 PHC contacts were recorded. The SMR remained stable during the named GP model years but began to decrease during the restricted-list GP model, falling below expected levels from 2016 onward. Excess deaths decreased from 615 in 2004 in the named GP model to -29 by 2018, when the restricted-list GP model was in operation. Leading causes of death were circulatory diseases (41.1%), cancers (20.4%) and neurological conditions (17.8%), with a decrease in circulatory disease deaths and an increase in cancer and dementia-related deaths over time.

The transition to the restricted-list GP model was associated with a lower SMR and fewer excess deaths in older adults. These findings highlight the importance of ongoing assessment of PHC models to ensure they meet evolving healthcare demands.
