Primary preventive screening

Cost-effectiveness of population screening for atrial fibrillation: the STROKESTOP study

Lyth, J., Svennberg, E., Bernfort, L., Aronsson, M., Frykman, V., Al-Khalili, F., Friberg, L., Rosenqvist, M., Engdahl, J., & Levin, L. Å. (2023). European heart journal, 44(3), 196–204.


Aims: Previous studies on the cost-effectiveness of screening for atrial fibrillation (AF) are based on assumptions of long-term clinical effects. The STROKESTOP study, which randomised 27 975 persons aged 75/76 years into a screening invitation group and a control group, has a median follow-up time of 6.9 years. The aim of this study was to estimate the cost-effectiveness of population-based screening for AF using clinical outcomes.

Methods and results: The analysis is based on a Markov cohort model. The prevalence of AF, the use of oral anticoagulation, clinical event data, and all-cause mortality were taken from the STROKESTOP study. The cost for clinical events, age-specific utilities, utility decrement due to stroke, and stroke death was taken from the literature. Uncertainty in the model was considered in a probabilistic sensitivity analysis. Per 1000 individuals invited to the screening, there were 77 gained life years and 65 gained quality-adjusted life years. The incremental cost was €1.77 million lower in the screening invitation group. Gained quality-adjusted life years to a lower cost means that the screening strategy was dominant. The result from 10 000 Monte Carlo simulations showed that the AF screening strategy was cost-effective in 99.2% and cost-saving in 92.7% of the simulations. In the base-case scenario, screening of 1000 individuals resulted in 10.6 [95% confidence interval (CI): -22.5 to 1.4] fewer strokes (8.4 ischaemic and 2.2 haemorrhagic strokes), 1.0 (95% CI: -1.9 to 4.1) more cases of systemic embolism, and 2.9 (95% CI: -18.2 to 13.1) fewer bleedings associated with hospitalization.

Conclusion: Based on the STROKESTOP study, this analysis shows that a broad AF screening strategy in an elderly population is cost-effective. Efforts should be made to increase screening participation.

The Swedish Dental and Pharmaceutical Benefits Agency, TLV, has made a health economic assessment of different methods for diagnosing atrial fibrillation in primary care. The results show that the care pathway with Zenicor-ECG is more efficient for healthcare.

Cost-effectiveness of screening for atrial fibrillation in a single primary care center at a 3-year follow-up

A post hoc analysis based on a cross-sectional screening study for AF among 70–74-year old patients, who were registered at a single primary care center, was followed for three years for mortality. Screening for AF among 70–74-year olds in primary care using intermittent ECG appears to be cost-effective at 3-year follow-up with high anticoagulants adherence and no increased mortality.

As part of a Government commission to evaluate medical technology, based on figures from the StrokeStop study, TLV (The Dental and Pharmaceutical Benefits Agency) has carried out a health economics assessment of primary preventive fibrillation screening. The report shows that such screening using a thumb ECG is cost-effective.

In a globally unique study at Karolinska Institutet, 13.000 people were offered screening for atrial fibrillation with Zenicor-ECG. Five percent of the participants were identified as new candidates for treatment with oral anticoagulants. According to this Health economical study, based on the results from the STROKESTOP study, systematic mass screening for atrial fibrillation with Zenicor-ECG is cost-effective.

Based on figures from the Propp-Stopp study, researchers in Linköping have been able to confirm that screening of 75-year-old stroke patients for silent atrial fibrillation is very cost-effective and after seven years, savings in terms of healthcare costs can even be seen. In the studies Zenicor-EKG has proved to be both more sensitive and result in lower costs than Holter-EKG.
