Preliminary clinical study of outpatient anterior cervical discectomy and fusion in Chinese Han patients: a retrospective analysis.

Abstract

Study design: A retrospective analysis.

Purpose: To investigate the safety, clinical efficacy, and health economic benefits of anterior cervical discectomy and fusion (ACDF) among Chinese Han patients in an outpatient setting.

Overview of literature: For years, ACDF has been conducted in an outpatient setting in Western countries. However, studies addressing whether this type of surgery carries the same level of safety and clinical efficacy for Chinese Han patients are scarce.

Methods: A retrospective analysis was conducted based on the clinical data of Han patients who underwent ACDF between January 2022 and May 2024. A total of 84 patients were included, and 1:1 propensity score matching was employed between 42 patients who underwent outpatient ACDF and 42 who underwent inpatient ACDF before evaluating the safety and clinical efficacy.

Results: The mean follow-up period was 3.9 months (range, 1-12 months). The fibrinogen and activated partial thromboplastin time of the outpatient and inpatient groups were comparable, which were different from the data of Caucasians in the literature. No significant differences in adverse events within 30 days following the surgery were found between the outpatient (28.6%) and inpatient (33.3%) groups. No significant differences in the Japanese Orthopaedic Association score and Neck Disability Index were noted between the two groups 1 month before and after the surgery. The readmission rates were low in the outpatient group 30 days after surgery (2.4%).

Conclusions: Consistent with the Caucasian and Black, one- to two-level ACDF conducted on Chinese Han patients in an outpatient setting demonstrated comparable safety and clinical effectiveness to routine inpatient settings.
