Risk factors for unplanned readmission in total laryngectomy patients.

OBJECTIVE

To determine which patient or surgical factors affect the likelihood of unplanned readmission (within 30 days) after total laryngectomy (TL).

METHODS

Retrospective chart review of all patients who underwent TL at a single institution from April 2007 through August 2016. Primary outcome was unplanned readmission to the hospital within 30 days of discharge. Univariable and multivariable logistic regression were performed to identify risk factors for unplanned readmission.

RESULTS

Two hundred seventy-eight patients met inclusion criteria. Twenty-nine patients (10.4%) had unplanned readmissions within 30 days. The most common reasons for readmission were pharyngocutaneous fistula (n = 15), neck abscess (n = 3), and wound breakdown (n = 4). Average time to unplanned readmission was 11.2 days (range 0-27 days). Fistula (OR 30.259; 95% CI, 9.186, 118.147; P ≤ .001), postoperative pneumonia (OR 9.491; 95% CI, 1.783, 53.015; P = .008), and history of cardiac disease (OR 7.074; 95% CI, 2.324, 25.088, P = .001) were independently associated with an increased risk of 30-day unplanned readmission on multivariate analysis. However, return to OR on initial admission was associated with a lower risk of unplanned readmission (OR 0.075; 95% CI, 0.009, 0.402; P = .007). Unplanned readmission was associated with a delay in initiation of adjuvant radiation (OR 1.494; 95% CI, 1.397, 1.599; P < .001).

CONCLUSION

Unplanned readmission occurs in a small but significant number of TL patients. Patients who have a 30-day unplanned readmission may be at risk for a delay in initiation of adjuvant therapy.
