Abstract

Objectives: Good perioperative care is aimed at rapid recovery, without complications or readmissions. Length of stay (LOS) is influenced not only by perioperative care routines but also by patient factors, tumour factors, treatment characteristics and complications. The present study examines variation in LOS between hospitals after minimally invasive lung resections for both complicated and uncomplicated patients to assess whether LOS is a hospital characteristic influenced by local perioperative routines or other factors.

Methods: Dutch Lung Cancer Audit (surgery) data were used. Median LOS was calculated on hospital level, stratified by the severity of complications. Lowest quartile (short) LOS per hospital, corrected for case-mix factors by multivariable logistic regression, was presented in funnel plots. We correlated short LOS in complicated versus uncomplicated patients to assess whether short LOS clustered in the same hospitals regardless of complications.

Results: Data from 6055 patients in 42 hospitals were included. Median LOS in uncomplicated patients varied from 3 to 8 days between hospitals and increased most markedly for patients with major complications. Considerable between-hospital variation persisted after case-mix correction, but more in uncomplicated than complicated patients. Short LOS in uncomplicated and complicated patients were significantly correlated (r = 0.53, P < 0.001).

Conclusions: LOS after minimally invasive anatomical lung resections varied between hospitals particularly in uncomplicated patients. The significant correlation between short LOS in uncomplicated and complicated patients suggests that LOS is a hospital characteristic potentially influenced by local processes. Standardizing and optimizing perioperative care could help limit practice variation with improved LOS and complication rates.
