The incidence and healthcare costs of persistent postoperative pain following lumbar spine surgery in the UK: a cohort study using the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES).


ABSTRACT: OBJECTIVE:To characterise incidence and healthcare costs associated with persistent postoperative pain (PPP) following lumbar surgery. DESIGN:Retrospective, population-based cohort study. SETTING:Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES) databases. PARTICIPANTS:Population-based cohort of 10?216 adults who underwent lumbar surgery in England from 1997/1998 through 2011/2012 and had at least 1?year of presurgery data and 2?years of postoperative follow-up data in the linked CPRD-HES. PRIMARY AND SECONDARY OUTCOMES MEASURES:Incidence and total healthcare costs over 2, 5 and 10 years attributable to persistent PPP following initial lumbar surgery. RESULTS:The rate of individuals undergoing lumbar surgery in the CPRD-HES linked data doubled over the 15-year study period, fiscal years 1997/1998 to 2011/2012, from 2.5 to 4.9 per 10?000 adults. Over the most recent 5-year period (2007/2008 to 2011/2012), on average 20.8% (95% CI 19.7% to 21.9%) of lumbar surgery patients met criteria for PPP. Rates of healthcare usage were significantly higher for patients with PPP across all types of care. Over 2?years following initial spine surgery, the mean cost difference between patients with and without PPP was £5383 (95% CI £4872 to £5916). Over 5 and 10 years following initial spine surgery, the mean cost difference between patients with and without PPP increased to £10 195 (95% CI £8726 to £11?669) and £14 318 (95% CI £8386 to £19?771), respectively. Extrapolated to the UK population, we estimate that nearly 5000 adults experience PPP after spine surgery annually, with each new cohort costing the UK National Health Service in excess of £70?million over the first 10 years alone. CONCLUSIONS:Persistent pain affects more than one-in-five lumbar surgery patients and accounts for substantial long-term healthcare costs. There is a need for formal, evidence-based guidelines for a coherent, coordinated management strategy for patients with continuing pain after lumbar surgery.
