Impact of primary care physician continuity on survival in patients with atrial fibrillation: a retrospective cohort study

  • retrospective cohort study
  • Cox regression and Fine-Gray competing risk models, adjusted for potential confounders

Authors' conclusion

Longitudinal COC in primary care is associated with improved clinical management, including better OAC indication, and a significant reduction in all-cause mortality among patients with AF. The survival benefit of seeing the same physician appears to extend beyond anticoagulation optimization, highlighting the pleiotropic value of the patient-physician relationship.

Study context

Population
Patients with atrial fibrillation (AF) referred by primary care physician (PCPs) between January 2010 and December 2023 in the Santiago de Compostela healthcare area (Spain)all patients with AF referred by PCPs
Participants
17,889 patients
Exposure
PCP stability vs interrupted continuity of care (COC)

Main finding

As reported in the abstract

Annual referral rate

PCP stability

1.5

interrupted COC

1.8

P < 0.001

Observational data: associations, not effects.

Further findings

Adequate OAC indication according to the CHA2DS2-VASc score · higher with PCP stability

P < 0.001

Outcomehazard ratio (95% CI)P value
All-cause mortality · reduced with COC · benefit remained robust after sensitivity analyses0.79 (0.69–0.91)

Stroke or haemorrhagic complications

No significant differences
  • competing risk analysis suggests that the higher mortality rate in the interrupted COC group likely precluded the observation of non-fatal events
