High lung cancer surgical procedure volume is associated with shorter length of stay and lower risks of readmission and death: national cohort analysis in England.Henrik Møller (1, 2, 3, 4), Shama Sheikh (2), Lars Holmberg (1), Erik Jakobsen (5), Jesper Lagergren (1), Richard Page (6), Michael D. Peake (3), Neil Pearce (7), Arnie Purushotham Hospitals with large lung cancer surgical resection volumes were less conservative in their selection of patients for surgical management, and provided a higher resection rate to their geographical population. The large hospitals had shorter length of stay and the odds of readmission were 15% lower in the highest hospital volume quintile compared with the lowest quintile. Mortality risks were 1% after 30 days and 3% after 90 days. Patients from hospitals in the highest volume quintile had about half the odds of death within 30 days than patients from the lowest quintile.Variations in outcomes were all in the same direction, with consistent better outcomes in the larger hospitals. This gives support to the ongoing trend towards centralisation of clinical services, but service re-organisation needs to take account of not only the size of hospitals but also referral routes and patient access.
