Abstract

Background Surgeon‐level operative mortality is widely seen as a measure of quality after gastric and oesophageal resection. This study aimed to evaluate this alongside a compound‐level outcome analysis. Methods Consecutive patients who underwent treatment including surgery delivered by a multidisciplinary team, which included seven specialist surgeons, were studied. The primary outcome was death within 30 days of surgery; secondary outcomes were anastomotic leak, Clavien–Dindo morbidity score, lymph node harvest, circumferential resection margin (CRM) status, disease‐free (DFS), and overall (OS) survival. Results The median number of annual resections per surgeon was 10 (range 5–25), compared with 14 (5–25) for joint consultant teams (P = 0·855). The median annual surgeon‐level mortality rate was 0 (0–9) per cent versus an overall network annual operative mortality rate of 1·8 (0–3·7) per cent. Joint consultant team procedures were associated with fewer operative deaths (0·5 per cent versus 3·4 per cent at surgeon level; P = 0·027). The median surgeon anastomotic leak rate was 12·4 (range 9–20) per cent (P = 0·625 versus the whole surgical range), overall morbidity 46·5 (31–60) per cent (P = 0·066), lymph node harvest 16 (9–29) (P < 0·001), CRM positivity 32·0 (16–46) per cent (P = 0·003), 5‐year DFS rate 44·8 (29–60) per cent and OS rate 46·5 (35–53) per cent. No designated metrics were independently associated with DFS or OS in multivariable analysis. Conclusion Annual surgeon‐level metrics demonstrated wide variations (fivefold), but these performance metrics were not associated with survival.
