Abstract
- <bold>Aim: </bold>This study compared the cost-effectiveness of botulinum neurotoxin A (BoNT-A) injections with two-duct ligation of the submandibular glands as treatment for severe drooling after one treatment cycle.<bold>Method: </bold>The study was part of a larger, partly single-blinded, randomized clinical trial (trialregister.nl identifier NTR3537). Data were collected between 2012 and 2017. Evaluation was at 32 weeks after one treatment cycle. Fifty-seven patients with cerebral palsy or other neurological, non-progressive disorders and severe drooling classified as having a drooling frequency ≥3 or a drooling severity ≥2, in whom conservative treatment was deemed ineffective, were randomized to treatment by BoNT-A or two-duct ligation. An incremental cost-effectiveness ratio (ICER) was calculated using the success rates as the measure of benefit. Treatment success was defined as a decrease ≥50% from baseline to 32 weeks in the subjective visual analogue scale for the severity of drooling or the objective drooling quotient.<bold>Results: </bold>Fifty-three patients were analysed (22 females, 31 males; mean age 11y, range 8-22y). Average costs for one treatment cycle, which included one BoNT-A injection, were €1929 (standard error 62) for BoNT-A and €3155 (standard error 99) for two-duct ligation. Treatment success was in favour of two-duct ligation (63% vs 27%; number needed to treat 3). The ICER was €34 per 1% gain in treatment success in favour of two-duct ligation versus BoNT-A.<bold>Interpretation: </bold>The additional cost of two-duct ligation is to some extent offset by a larger treatment success rate compared with BoNT-A.<bold>What This Paper Adds: </bold>Botulinum neurotoxin A (BoNT-A) is less expensive per percentage of success than two-duct ligation. The additional cost of two-duct ligation over BoNT-A is offset by greater treatment success. [ABSTRACT FROM AUTHOR]
