The Effectiveness and Cost-Effectiveness Analysis of Community Stroke Screening Intervention Model Based on Mar-kov Model
Objective:To explore the impact and cost-effectiveness of community stroke screening intervention mode on stroke risk.Methods:A total of 3 561 community people over 40 years old who participated in screening intervention in 2017,2019 and 2021 were selected as research objects,and stroke risk was divided into low risk,medium risk and high risk.A Markov model was established to explore the impact of screening intervention mode on stroke risk in community population.The cost increment during the phase I trial was calculated,and the life year increment was adjusted according to the quality estimate of previous studies.The cost-effectiveness increment ratio was calculated,and the screening intervention mode was evaluated,and univariate sensitivity analysis was performed.Results:Within a certain range,intervention screening could effectively shift the status of residents to the low-risk direction,and finally stabilize the distribution of low-risk,medium-risk and high-risk were 47.4％,31.0％and 21.6％.The incremental cost of interventional screening was 160 245 yuan,the incremental quality-adjusted life year was 151.129 yuan,and the incremental cost-effectiveness ratio(ICER)was 1 060.319 yuan/QALY,which was less than 1 times the per capita GDP.The intervention program was fully cost-effective.Conclusion:Screening intervention can promote the transformation of the commu-nity population to a low-risk state of stroke in the prevention stage,and this approach has good cost-effectiveness performance.It is recommended that the primary medical and health institutions that are not enough to fully implement the integrated process ser-vice of community prevention and treatment of stroke should first implement low-cost screening intervention.
