BackgroundPediatric rheumatic diseases are chronic illnesses that pose a huge economic burden to children and their families; one of the most common is pediatric systemic lupus erythematosus (pSLE). The direct cost of pSLE has been studied in other countries. In the Philippines, this was only studied in the adult population. This study aimed to determine the direct cost of pSLE in the Philippines and its cost predictors.MethodsA total of 100 pSLE patients were seen from November 2017 to January 2018 at the University of Santo Tomas. Informed consent and assent forms were obtained. A total of 79 patients met the inclusion criteria and parents were asked to answer a questionnaire. Data were tabulated and were subjected to statistical analysis. Cost predictors were estimated using a stepwise log linear regression.ResultsA total of 79 pediatric SLE patients, with a mean age of 14.68 ± 3.24 years, 89.9% of which were females, with a mean disease duration of 36.08 ± 23.54 months, were included in this study. A total of 65.82% had lupus nephritis and 49.37% were in flare. The mean annual direct cost for pediatric SLE patient was 162,764.81 PHP (USD 3,047.23). Majority of the expense was for medications. Regression analysis showed that the predictors of increased cost in doctor's fee in clinic visits (p-value 0.000) and IV infusion (p-value 0.01) were the higher combined income of the parents.ConclusionThis is a preliminary study on the mean annual direct cost of pediatric SLE patients in a single center in the Philippines. Pediatric SLE patients with nephritis and other target organ damage were seen to increase the cost up to 2–3.5×. Patients in flare also had a higher cost of up to 1.6×. The overall cost driver of this study was the parent's or caregivers combined income. Further analysis showed that cost drivers in the subcategories include the age, sex and parent's/caregiver's educational attainment.
