“…In general, LOS is considered an important prognostic variable for a positive surgical outcome, although its elasticity may limit its value as a parameter for comparisons [27]. The LOS varies according to different centres, referral patterns, healthcare systems and access to homecare support, and there is substantial heterogeneity in protocols, making comparisons difficult [5,6,9,28]. Auditing the present results, the authors compared actual LOS with timely LOS according to standardized discharge criteria, revealing a further reduction to a median of 7 days; however, this effect was seen in both groups.…”
