Patient questionnaire following closure of tracheotomy fistula: percutaneous vs. surgical approaches

BACKGROUND Tracheotomy is an indispensable component in intensive care management. Doctors in charge of the intensive care unit (ICU) usually decide whether tracheotomy should be performed. However, long-term follow-up of a closed fistula by these doctors is rarely continued in most cases. Doctors in charge of the ICU should be interested in the long-term prognosis of tracheotomy. The purpose of this study was to evaluate whether different tracheotomy procedures affect the long-term outcome of a closed tracheal fistula. METHODS We mailed questionnaires to patients undergoing tracheotomy in Fukushima Medical University Hospital between January 2008 and December 2010. Questions concerned problems related to perception, laryngeal function, and the appearance of a closed fistula. Patients were classified into percutaneous tracheotomy (PT) group and surgical tracheotomy (ST) group. We evaluated the statistical significance of differences in the frequency and degree of each problem between the two groups. A door-to-door objective evaluation using the original scoring system was then performed for patients who replied to the mailed questionnaire. We evaluated the percentage of patients with high scores as well as the mean scores for problems with function and appearance. RESULTS We received completed questionnaires from 28/40 patients in the PT group and 35/55 patients in the ST group. There were no significant differences in age, mean hospital stay, or APACHE II score between the groups. Regarding problems with appearance, the outcomes of PT were significantly better than those of ST with respect to self-evaluation (p = 0.04) and the frequency (p = 0.03) and degree (p = 0.02) of scar unevenness according to door-to-door evaluation. However, there were no significant differences in the frequency or degree of self-evaluation in problems with perception and function between the two groups. There were no significant differences in the frequency or degree of door-to-door evaluation of problems with function. CONCLUSIONS This study shows that PT might be superior to ST with respect to problems with long-term appearance. Continuous follow-up of closed tracheal fistulas can help assure that patients recovering from a critical condition experience a better return to their former lives. A systematic follow-up of post-critical-care patients is required.
