摘要
Objective This study explored how different hospital volumes and surgeon volumes affect thyroidectomy outcomes in terms of length of stay (LOS), costs, and in-hospital mortality. Data Sources MEDLINE and EMBASE databases. Review Methods This study retrospectively analyzed a cohort of 125,037 thyroidectomy patients treated at Taiwan hospitals from 1996 to 2010. Relationships between hospital/surgeon volume and patient outcomes were retrospectively analyzed by propensity score matching. In conjunction with the retrospective study, a systematic review and meta-analysis of the relevant literature also were performed. Results The mean LOS for all thyroidectomies performed during the study period was 3.3 days, and the mean cost was $1193.5. Both high-volume hospitals and high-volume surgeons were associated with significantly shorter LOS and lower costs compared with their low-volume counterparts (P < .001). Different volume groups had similar in-hospital mortality rates. The meta-analysis results consistently showed that the benefits of high-volume hospitals/surgeons are reduced LOS and costs. However, low in-hospital mortality rates were associated with high-volume surgeons but not with high-volume hospitals. Conclusions This meta-analysis showed that patients who received thyroidectomies performed by high-volume hospitals and surgeons had shorter LOS and lower costs compared with those treated by low-volume hospitals and surgeons. In addition, in-hospital survival rates were better in patients treated by high-volume surgeons. Further research is needed to define the learning curve for thyroidectomy and to clarify how hospital volume and surgeon volume affect its success rate.
