Cost Effectiveness Analysis of the Prevention and Treatment of Osteoporosis among the Entire Population in Fenglin Community, Shanghai Based on Markov Chain

Background With the gradual deepening of the comprehensive reform of community health services, the prevention and control of single diseases for the entire population in the community is also constantly being optimized, However, there is still a lack of appropriate evaluation methods in the community to reflect its prevention and control effectiveness evaluation. Objective By analyzing and exploring the cost effect of the existing whole-population prevention and control measures of osteoporosis in Fenglin community, from 2016 to 2022, this paper answers the initial results and possible problems of the whole-population prevention and control of single disease in the community. Methods This study conducted a cost-effectiveness analysis on 4 293 community residents who received osteoporosis prevention and treatment in Fenglin community from 2016 to 2022. Divide the research object into three states based on bone density values: healthy, low bone mass, and osteoporosis, and construct a Markov model to analyze the influencing factors of different state transitions. And based on the predicted values of the Markov model combined with quality adjusted life years (QALY) , the increment of quality adjusted life years (QALY) is calculated. All costs invested in prevention and control work from 2016 to 2022 are counted, and the effectiveness of prevention and control is evaluated by the cost/quality adjusted life year increment ratio. Quality adjusted life years (QALY) are obtained by calculating the health utility value and expected life determined through literature search. Results The total cost of osteoporosis prevention and treatment in Fenglin community was 33 814 102.15 yuan. The total quality-adjusted life years of 4 293 community osteoporosis prevention and treatment population were 77 098.288 9 at the first diagnosis, the average per capita was 17.959, and the standard deviation was 9.34. At the second diagnosis, the total quality-adjusted life years were 79 616.936 1, the mean per capita was 18.546, the standard deviation was 9.342, and the difference between the two diagnoses was 2 518.647 2. The incremental cost-effectiveness ratio (ICER) is 2 132.907 0 yuan /QALY, and the incremental cost-effectiveness ratio (ICER) is less than 1 times (66 965.10 yuan) per capita GDP, indicating that the intervention scheme is fully cost-effective. Conclusion This study combined Markov model and quality-adjusted life years (QALY) to make a preliminary evaluation of the prevention and treatment effect of osteoporosis in Fenglin community. The results showed that the intervention program of osteoporosis prevention and treatment in Fenglin community was worth investing, and provided a certain basis for the accurate prevention and treatment decision of osteoporosis in the future.
