Research Article: Index hospital cost of adverse events following thoracic surgery: a systematic review of economic literature
Abstract:
Objectives Adverse events (AEs) following thoracic surgery place considerable strain on healthcare systems. A rigorous evaluation of the economic impact of thoracic surgical AEs remains lacking and is required to understand the value of money of formal quality improvement initiatives. Our objective was to conduct a systematic review of all available literature focused on specific cost of postoperative AEs following thoracic surgery. Design Systematic review of the economic literature was performed, following recommendations from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Data sources An economic search filter developed by the Canadian Agency for Drugs and Technologies in Health was applied, and MEDLINE, Embase and The Cochrane Library were searched from inception to January 2022. Eligibility criteria We included English articles involving adult patients who underwent a thoracic surgical procedure with estimated costs of postoperative complications. Eligible study designs included comparative observational studies, randomised control trials, decision analytic or cost-prediction models, cost analyses, cost or burden of illness studies, economic evaluation studies and systematic reviews and/or meta-analyses of cost analyses and cost of illness studies. Data extraction and synthesis Two reviewers independently screened titles and abstracts in the first stage and full-text articles of included studies in the second stage. Disagreements during abstract and full-text screening stages were resolved via discussion until a consensus was reached. Studies were appraised for methodological quality using the Critical Appraisal Skills Program checklist. Results 3349 studies were identified: 20 met inclusion criteria. Most were conducted in the USA (12/20), evaluating AE impact on hospital expenditures (18/20). 68 procedure-specific AE mean costs were characterised (USD$). The most commonly described were anastomotic leak (mean:range) (USD$49 278:$6 176–$133 002) and pneumonia ($12 258:$2608–$34 591) following esophagectomy, and prolonged air leak ($2556:$571–$3573), respiratory failure ($19 062:$11 841–$37 812), empyema ($30 189:$23 784–$36 595), pneumonia ($15 362:$2542–$28 183), recurrent laryngeal nerve injury ($16 420:$4224–$28 616) and arrhythmia ($6835:$5833–$8659) following lobectomy. Conclusions Hospital costs associated with AEs following thoracic surgery are substantial and varied. Quantifying costs of AEs enable future economic evaluation studies, which could help prioritising value-directed quality improvement to optimally improve outcomes and reduce costs.
Introduction:
Adverse events (AEs, defined as a deviation from the expected recovery from surgery) are common following thoracic surgery. 1 Despite the improvement in perioperative patient management and refinement of surgical technique over the preceding decades, patients continue to experience a substantial burden of AEs, producing both short-term and long-term sequalae. Evidence supports a reduction in quality of life (QoL), prolonged hospitalisations with intense resource utilisation 2 and impaired postoperative recovery…
