Factors influencing surgeon decision-making by measuring waiting time for pediatric ventilation tube insertions

Background: The surgeon and physician's decision-making may be influenced by many factors. The clinical practice guideline suggested that watchful waiting for 3 months should be the initial management for pediatric otitis media with effusion. The waiting time of ventilation tube insertion for pediatric patients is a proper measurement for physician decision-making. This study investigated factors influencing the waiting time for pediatric ventilation tube insertion and to explore factors influencing physician decision-making. Methods: Information associated with all patients under 18 years of age who received ventilation tube insertions from July 1, 2000 to December 31, 2009 were retrieved and analyzed from a nationwide, population-based administrative database. The waiting time before ventilation tube insertions from the time of diagnosis of otitis media with effusion was recorded. Certain factors that would influence the waiting time were identified. At the same time, how these factors influenced clinical decision-making were also identified. Results: The waiting time decreased as patient age increased (p < 0.001), and increased as the recent frequency of upper respiratory tract infection diagnosis increased (p < 0.001). Patients who received simultaneously bilateral ventilation tube insertions had shorter waiting time than those who had unilateral surgery (p < 0.01) and patients who had undergone ventilation tube insertions in a tertiary referral center generally had longer waiting times (p < 0.001). Conclusion: The waiting time of ventilation tube insertions for pediatric otitis media with effusion can be influenced by many factors. Patients with older age and undergone simultaneously bilateral ventilation tube insertion had shorter waiting time. Patients who had more upper respiratory tract infection episodes and who received ventilation tube insertions in a tertiary referral center setting were subject to longer waiting times.
