Background: Pterygium is a common disease in medical practice. Many patients had undergone pterygium surgery in each year, but the expense of pterygium surgery for service provider has not been studied in Thailand.
Objective: To compare the expense of pterygium surgery among various health funds, and different surgical methods at Thammasat University Hospital.
Material and Methods: A total of 179 patients who underwent pterygium surgery at Thammasat University Hospital in fiscal year 2020 (1 October 2019 – 30 September 2020) were enrolled. The data including an expense which patients need to pay, type of surgical methods and health fund coverage were obtained retrospectively from computer-based medical record. The expense was analyzed with different type of surgical methods and various health funds. One-way ANOVA and post hoc test were used to compare the mean differences between groups. A p-value less than 0.05 was considered statistically significant.
Result: An average total expense (including surgical and medication expense) of pterygium surgery with amniotic membrane graft (fibrin glue), conjunctival autograft (suture), and amniotic membrane graft (suture) method were 13,728.86+/-409.34, 6,507.54+/-509.64 and 6,463.33+/-542.99 baht, respectively. Of 160 patients using amniotic membrane graft (suture) method, an average total expense of the patients under Civil Servants’ Medical Benefit Scheme, Universal Coverage, self-pay, and Social Security Scheme were 6,551.51+/-517.42, 6,425.09+/-597.20 baht, 6,283.11+/-551.48 and 6,025.71+/-410.10 baht, respectively.
Conclusion: The total expense of pterygium surgery with amniotic membrane graft (fibrin glue) method was significantly higher than those of conjunctival autograft (suture) and amniotic membrane graft (suture) method (p< 0.001). For pterygium surgery using amniotic membrane graft (suture) method, the total expense of patients under Civil Servants’ Medical Benefit Scheme was significantly higher than of self-pay and Social Security Scheme (p<0.05).
