Abstract

Purpose

Categorize data to investigate the surgeon volume outcome relationship in thyroidectomies. Determine the evidence base for recommending a minimum number of thyroidectomies performed per year to maintain surgical competency.

Methods

Data on thyroid operations in the United Kingdom Registry of Endocrine and Thyroid Surgery (UKRETS) from 01/09/2010 to 31/08/2016 was analysed. The primary outcome measure was permanent hypoparathyroidism (PH). Recurrent laryngeal nerve palsy (RLN) and post-operative haematoma were also examined. Exclusion criteria included patient age > 85 or < 18 years, and surgeons contributing <10 operations. Data analysis was performed using general additive models and mixed effect logistic regression for PH and binary logistic regression for others.

Results

For PH 10313 bilateral thyroid operations were analysed. The Annual rate (AR, p = 0.012) and nodal dissection (P < 10⁻⁷) were significant factors. 25,038 thyroidectomies were analysed to investigate the effect of surgeon Volume on RLN palsy and haematoma. Age, retrosternal goitre, routine laryngoscopy, re-operation, nodal Dissection, bilateral thyroidectomy, RLN monitoring and surgeon volume were significantly associated with RLN palsy. Post-operative haematoma showed no significant correlation to surgeon volume. Categorisation of AR showed that PH and RLN palsy rates declined in surgeons performing >50 cases/year to a minimum of 3% and 2.6% respectively in highest volume AR group (>100 cases/year).

Conclusion

Surgeon annual operative volume is a factor in determining outcome from thyroid surgery. Results are limited by a high proportion of missing data, which could potentially bias the outcome, but tentatively suggests the minimum recommended number of thyroid operations / year should be 50 cases.
