STUDY DESIGN: Retrospective database analysis. OBJECTIVES: To describe comorbidities, pain-related pharmacotherapy, healthcare resource use and costs among patients with spinal cord injury (SCI) newly prescribed pregabalin. SETTING: United Kingdom (UK). METHODS: Using The Health Improvement Network database, SCI patients newly prescribed (index event) pregabalin (N=72; average age 48 years; 53% female) were selected. Study measures were evaluated during both the 9-months pre-index and follow-up periods. RESULTS: Prevalent comorbidities included musculoskeletal disorders (51.4%), digestive disorders (23.6%) and urogenital disorders (20.8%). Opioids were the most frequently prescribed medications (pre-index, 58.3%; follow-up, 61.1%, P=not significant (NS)) followed by nonsteroidal anti-inflammatory drugs (43.1 and 45.8%, P=NS). Use of anti-epileptics (other than pregabalin) recommended for SCI neuropathic pain decreased (25.0 vs 12.5%, P=0.0290), whereas sedative/hypnotic use (18.1 vs 26.4%, P=0.034) increased during follow-up. Over 50% of patients had visits to specialists, and at least 1 in every 10 had laboratory/radiology-related visits. There were numerical decreases in proportions of patients with emergency room visits (22.2 vs 13.9%, P=NS) and hospitalizations (16.7 vs 12.5%, P=NS) during follow-up. Medication costs were higher during follow-up (median, £ 561.4 vs £ 889.5, P<0.0001). Costs of outpatient visits were similar during both study periods (£ 1082.1 vs £ 1066.1) as were total medical costs (£ 1689.0 vs £ 2169.4) when costs of pregabalin prescriptions were excluded. Inclusion of pregabalin costs resulted in higher (P<0.0001) total medical costs during follow-up. CONCLUSION: SCI patients had a high comorbidity, medication and healthcare resource use burden in clinical practice. Further research with larger sample sizes and more comprehensive data sources may serve to clarify study findings.
