Table 2 Probability data for the VTs strategy

From: Economic evaluation of surgical insertion of ventilation tubes for the management of persistent bilateral otitis media with effusion in children

Variable Probability Distribution for PSA Source Comments
Removal of VTs (1st insertion) 0.072 Beta ~ (6, 77) Phua et al. [14] Different risk has been predicted for subsequent removal procedures[14]
Removal of VTs (≥2 insertions) 0.171 Beta ~ (7, 34) Phua et al. [14]
Re-insertion of 2nd VTs 0.25 Beta ~ (25, 75) NCCWCH [7] Indifferent risk has been predicted for subsequent insertion procedures[7], which is in line with the suggestion by Sheahan et al.[49]. Distribution for PSA is based on the report that 25 out of 100 children require 2 or more insertions of VTs
Re-insertion of 3rd VTs 0.25 Beta ~ (25, 75) NCCWCH [7]
