Health Care Costs and Cost-effectiveness in Laryngotracheal Stenosis.

OBJECTIVE: Laryngotracheal stenosis (LTS) is resource-intensive disease. The cost-effectiveness of LTS treatments has not been adequately explored. We aimed to conduct a cost-effectiveness analysis comparing open reconstruction (cricotracheal/tracheal resection [CTR/TR]) with endoscopic dilation in the treatment of LTS. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary referral center (2013-2017). SUBJECTS AND METHODS: Thirty-four LTS patients were recruited. Annual costs were derived from the Department of Otolaryngology-Head and Neck Surgery, Johns Hopkins University. Cost-effectiveness analysis compared CTR/TR versus endoscopic dilation at a willingness-to-pay threshold of $50,000 per quality-adjusted life year (QALY) over 5- and 10-year time horizons. The incremental cost-effectiveness ratio (ICER) was calculated with deterministic analysis and tested for sensitivity with univariate and probabilistic sensitivity analysis. RESULTS: Mean LTS costs were $4080.09 (SE, $569.29) annually for related health care visits. The major risk factor for increased cost was etiology of stenosis. As compared with idiopathic patients, patients with intubation-related stenosis had significantly higher annual costs ($5286.56 vs $2873.62, P = .03). The cost of CTR/TR was $8583.91 (SE, $2263.22). Over a 5-year time horizon, CTR/TR gained $896 per QALY over serial dilations and was cost-effective. Over a 10-year time horizon, CTR/TR dominated dilations with a lower cost and higher QALY. CONCLUSION: The cost of treatment for LTS is significant. Patients with intubation-related stenosis have significantly higher annual costs than do idiopathic patients. CTR/TR contributes significantly to cost in LTS but is cost-effective versus endoscopic dilations for appropriately selected patients over a 5- and 10-year horizon.

Mitomycin-c application in airway stenosis surgery: analysis of safety and costs.

OBJECTIVE: This study describes a large series of patients receiving topical mitomycin-c (MMC) during airway surgery, including complications, and carries out a cost analysis for its use in laryngotracheal stenosis. STUDY DESIGN AND SETTING: Retrospective review, tertiary center. Airway patients receiving MMC are reviewed for demographics, stenosis characteristics, and MMC usage. A basic cost analysis is carried out. RESULTS: Fifty patients underwent 93 MMC applications (mean = 50.8 years, 25 male, 25 female). In 89 of 93 applications (96%), the concentration of MMC was 0.4 mg/ml. One major complication occurred (1.1%). The expense for MMC is $455; the mean cost for airway surgery is $7,840. It is estimated that if 1 of 17 MMC treated patients requires one less operation, the cost ratio is favorable. CONCLUSIONS: This large series contributes to literature that MMC is a safe adjunct to laryngotracheal surgery. The marginal cost for MMC application is favorable based on our basic cost analysis and existing efficacy data. SIGNIFICANCE: Mitomycin-c seems to be safe and cost-effective in endoscopic airway surgery. EBM RATING: C-4.

Long-segment tracheal stenosis: slide tracheoplasty and a multidisciplinary approach improve outcomes and reduce costs.

OBJECTIVE: Long-segment tracheal stenosis is rare, life-threatening, difficult, and expensive to treat. Management remains controversial. A multidisciplinary tracheal team was formed in 2000 to deal with a large number of children with airway problems referred for management. We review the effect of that service, comparing the era before and after the establishment of the multidisciplinary tracheal team. METHODS: From January 1998 through January 2004, 34 patients with long-segment tracheal stenosis (21 patients with cardiovascular anomalies) underwent surgical intervention. Cardiopulmonary bypass was used in all operations. Before the multidisciplinary tracheal team, pericardial patch tracheoplasty with or without an autograft technique was the preferred method of repair. After the multidisciplinary tracheal team, an integrated care plan preferring slide tracheoplasty was initiated, correcting cardiac lesions simultaneously. RESULTS: Before the establishment of the multidisciplinary tracheal team, pericardial patch tracheoplasty was performed in 15 of 19 patients. Twelve patients had a suspended pericardial patch tracheoplasty, 2 (17%) of whom died late after the operation. Of 3 patients who had had a simple unsuspended patch, 2 (67%) died early after the operation. Four patients were operated on with the tracheal autograft technique, 2 (50%) dying early in the postoperative period. After multidisciplinary tracheal team formation, in the era between 2001 and 2004, 15 patients were operated on with slide tracheoplasty, and there were 2 (13%) early postoperative deaths. A significant reduction in cost and duration of stay has been shown both in the intensive care unit and the hospital. CONCLUSION: Our data suggest that a formalized multidisciplinary team approach and a policy of primary slide tracheoplasty are beneficial in the management of children with long-segment tracheal stenosis.
