目的

本文分析近12年温州医科大学附属医院髋膝关节置换术的手术相关信息，以此为例反映近10年来关节置换术的手术趋势与卫生经济学趋势。

方法

本文通过收集统计温州医科大学附属医院2011年至2022年间行髋、膝关节置换患者的相关数据，包括患者年龄、性别、住院天数、主要诊断、手术名称、治疗费用等，比较其手术例数变化、患者年龄构成、性别差异、患者住院天数变化以及治疗相关费用，数据结果进行了t检验与logistic回归分析。

结果

本文研究了髋膝关节置换术共13 993例，其中髋关节置换术8 232例，膝关节置换术5 761例。在髋关节置换相关手术中，该院每年实行髋关节置换术例数逐年平均增长9.9%，患者平均年龄为（68±13）岁，男性患者占比42.2%，女性患者占比57.8%，患者平均住院时间较2011年减少46.7%，总治疗费用均值为53 936元，其中耗材费占比59.2%，总费用较2011年减少15.9%。在膝关节置换手术中，该院每年实行膝关节手术例数逐年平均逐年增长10.0%，患者平均年龄为（70±8）岁，男性患者占比30.4%，女性患者占比69.6%，患者平均住院时间较2013年减少41.5%，总治疗费用均值为48 559元，其中耗材费占比56.3%，总费用较2013年减少29.6%。

结论

行髋膝关节置换术的患者数量呈逐年上升趋势，虽然患者住院天数和住院费用较往年有了明显减少，但患者依然存在较大的治疗费用负担，降低手术的耗材费是降低总费用的重要环节。

Objective

To analyze the information related to hip and knee arthroplasty in a hospital affiliated to a medical university in the past 12 years, and take this as an example to reflect the surgical trend and health economic trend of joint arthroplasty in the past decade.

Methods

The data of patients undergoing hip and knee replacement in a hospital affiliated to a medical university from 2011 to 2022 were collected and analyzed, including patients’ age, gender, length of hospital stay, main diagnosis, name of operation, treatment cost, etc., and the changes in the number of operations, age composition of patients, gender differences, length of stay and treatment costs were compared. Statistical results were analyzed by t test and logistic regression analysis.

Results

A total of 13 993 cases of hip and knee arthroplasty were studied in this study, including 8 232 cases of hip arthroplasty and 5 761 cases of knee arthroplasty. In the hip arthroplasty related operations, the annul number of hip arthroplasty cases increased by an average of 9.9%, the average age of patients was (68±13)years, male patients accounted for 42.2% and female patients accounted for 57.8%. The average length of hospital stay of patients decreased by 46.7% compared with 2011. The average cost of total treatment was 53 936 yuan, of which the cost of consumables accounted for 59.2%. Total costs were 15.9% lower than the data in 2011. The annual number of knee surgery cases in the hospital increased by an average of 10.0% year by year, the average age of patients was (70±8) years, the proportion of male patients was 30.4%, and the proportion of female patients was 69.6%. The average length of hospital stay of patients was reduced by 41.5% compared with 2013, and the average total treatment cost was 48 559 yuan, of which consumables accounted for 56.3%. The total cost was 29.6% lower than in 2013.

Conclusions

The number of patients undergoing hip and knee replacement is increasing year by year. Although the hospitalization days and hospitalization costs of patients are significantly reduced compared with previous years, patients still have a large burden of treatment costs. Reducing the cost of surgical consumables is an important link to reduce the total cost.
