Reoperation after breast-conserving surgery for cancer in Australia: statewide cohort study of linked hospital data.

ABSTRACT:

Objectives

To investigate between-hospital variation in the probability of reoperation within 90 days of initial breast-conserving surgery (BCS), and the contribution of health system-level and other factors.

Design

Population-based, retrospective cohort study.

Setting

New South Wales (NSW), Australia.

Participants

Linked administrative hospitalisation data were used to define a cohort of adult women undergoing initial BCS for breast cancer in NSW between 1 July 2002 and 31 December 2013.

Primary outcome measures

Multilevel, cross-classified models with patients clustered within hospitals and residential areas were used to examine factors associated with any reoperation, and either re-excision or mastectomy, within 90 days.

Results

Of 34 458 women
