Does fast-tracking increase the readmission rate after pulmonary resection? A case-matched study.

Objectives: The most recent evolution of patient management after thoracic surgery implies the concept of fast-tracking. Since 2008, our unit has implemented a programme based on clinical protocols and standardized pathways of care aimed to reduce the postoperative stay after major lung resection. The objective of this study was to verify the safety of this policy by monitoring the patient readmission rate.

Methods: This is a prospective observational study on 914 consecutive pulmonary lobectomies performed at our institution from January 2000 to October 2010. Since we started the fast-tracking program in January 2008, we divided the patients into two groups: early period (678 patients, 2000-2007) and recent period (236 patients, 2008-October 2010). Several baseline and operative factors were used to build a propensity score that was applied to match the recent group patients with their early group counterparts. These two matched groups were then compared in terms of early outcomes and readmission rate. Readmission was defined as a re-hospitalization for any cause related to the operation within 30 days after discharge. We excluded from the analysis those patients with in-hospital mortality.

Results: Propensity score yielded 232 well-matched pairs operated on in the early (non-fast-tracked patients) and most recent period (fast-tracked patients). The fast-tracking management resulted in a postoperative stay reduction of 2.8 days (P < 0.0001), with a 3-fold higher proportion of patients discharged before the sixth postoperative day (P < 0.0001). Nevertheless, we did not observe any differences in terms of readmission rate between the two periods.

Conclusions: In our experience, the implementation of a fast-tracking program after pulmonary lobectomy was very effective and safe. It led to a postoperative reduction of hospital stay without an increase in the readmission rate.
