Background:
Dipstick urine tests are a simple and inexpensive method for detecting kidney and urological diseases, such as IgA nephropathy and bladder cancer. The nationwide mass screening program, Specific Health Checkup (SHC), started in Japan in 2008 and targeted all adults between 40 and 74 years of age. Dipstick urine tests for proteinuria and glucosuria are mandatory as part of the SHC, but dipstick urine tests for hematuria are not. However, the dipstick hematuria test is often administered simultaneously with these mandatory tests by some health insurers. Hematuria is common in Japanese general screening participants, particularly elderly women, and the necessity of mass screening using the dipstick hematuria test has been discussed. This study aimed to evaluate the cost-effectiveness of mass screening for dipstick hematuria tests in addition to the SHC.
Methods:
Using a decision tree and Markov modeling, we conducted a cost-effectiveness analysis from a Japanese societal perspective.
Results:
Compared with the current SHC, mass screening for dipstick hematuria tests, in addition to the SHC, costs less and gains more, which means cost-saving. Similar findings were observed in the sex-specific analysis.
Conclusion:
Our results suggest that mandating the dipstick hematuria test could be justifiable as an efficient use of finite healthcare resources. The results have implications for mass screening programs not only in Japan but worldwide.
