Healthcare Resource Utilisation and Costs Saved with Earlier Diagnosis of Common Variable Immune Deficiency: Using UK Primary Care Electronic Health Records
Author(s)
ABSTRACT WITHDRAWN
OBJECTIVES To quantify the direct medical cost of achieving an earlier diagnosis of Common Variable Immune Deficiency (CVID)with a digital health tool, from a payer perspective. METHODS 501,188 primary care electronic health records (EHRs) were scanned and 21 patients identified with the diagnostic code for CVID (SNOMED CT code: 23238000). Using a digital health tool, five CVID patients could be identified on average 5.2 (1-10) years earlier. We analysed the EHRs of the 21 CVID patients with at least 5 years of EHR entries before the first diagnosis (n=15). We examined the codes related to laboratory tests, clinical visits, referrals, and primary care interventions(medications & procedures) possibly attributed to CVID. Cost data from the NHS National tariff 2020/21 and private care tariff were applied to the identified codes to calculate the direct medical costs incurred in the 5 years before diagnosis. RESULTS Total healthcare resource utilisation associated with CVID for the 15 study patients in the 5 years before diagnosis was 290 laboratory tests, 171 clinical visits, 45 referrals and 8 interventions. This equates to a total direct medical cost of £18,220 in primary care and an average cost of £1,215 (£33- £3,319) per patient. The average costs per patient in the year before diagnosis was £391 (£0-£914), and in the second, third, fourth and fifth year before diagnosis £223 (£0-£1,042), £218 (£0-£703), £163 (£0-£460) and £220 (£0-£873) respectively. CONCLUSIONS This study demonstrates the use of EHRs as an approach to measure the potential economic burden of diagnostic delay in diseases with low prevalence in the UK. Digital health tools can result in potential cost-savings in primary care through early diagnosis of CVID.
