Abstract
The weekend effect has been defined as a real or perceived decline in patient care provided on weekends and that provided on weekdays. The primary aim of this study was to investigate the association between day of surgery and length of stay for patients receiving elective lower limb joint arthroplasty in a large NHS teaching hospital. Data were obtained from a prospectively collected database of consecutive patients undergoing elective primary total knee and hip arthroplasty. Patient and clinical variables were collected alongside length of hospital stay. Data were anonymised and analysed using a multiple linear regression model. A total of 3,544 knee and 3,277 hip replacements were included. No association was found between length of stay and day of surgery for either procedure. A significant association was noted between longer length of stay and increasing age, higher American Society of Anesthesiologists grade and male compared with female gender. No evidence of a weekend effect was identified. Certain patient factors predicted longer hospital stay and focussing additional resources on these patient groups may prove a useful strategy in reducing overall length of stay. Length of stay reduced across the time period included in this review while maintaining equality between the days of the week, which represents the successful management of weekend services.
