Objective: To explore the hospital costs for age-related cataract based on clinical paths. Methods:The hospital information system of the Computer Room in our hospital was searched for the initial pages of patientswith age-related cataract who were admitted to the Department of Ophthalmology in our hospital and had beenplaced on a clinical path from January 2017 to December 2018. Based on the International Classification of Diseas-es

Tenth Revision

Clinical Modification

patients who were primarily diagnosed with age-related cataract（code:H25.901） and underwent phacoemulsification（code: 13.4101） and primary implantation of artificial lens（code:13.7101） were enrolled and analyzed for the hospital costs for treating their cataracts. Results: The study included393 patients with monocular cataract. The total cost for these patients was $9 192（8 374

10 618）. In the cost com-position

the top three were material fee median: $4158（3 643

4 623）

surgery fee median: $1 725（1 725

2588）

and examination fee median: $1 276（1 079

1 536）

accounting for 44.8%

20.6%

and 13.6%

respec-tively

of the total cost. The treatment cost of male patients was significantly higher than that of female patients（Z =2.267

P = 0.023）. There was a significant difference in drug expenses between different age groups（Z = 9.817

P =0.007）

with significantly higher fees incurred by patients aged ≥ 70 years than by patients aged under 70 years（P < 0.05）. Conclusion: A reasonable calculation of the cost composition of age-related cataract as a single diseaseprovides a theoretical basis for standardized cost accounting and diagnosis-related groups for the disease. However

more high-quality and large-sample studies are needed in the future to further explore the costs of new projects andtechnologies related to age-related cataract as a single disease and the most reasonable disease cost accounting.
