Predictors of Pain Management Outcomes Following Orthopaedic Surgery: A Systematic Review

Up to 80% of patients in the United States report dissatisfaction with pain management following orthopaedic surgery. Inadequate pain management is linked to negative outcomes, including increased costs, readmission rates, and chronic pain risk. Traditional pain management protocols often emphasise the biological components of pain, overlooking psychological and social. This systematic review addresses this gap by answering two key questions: (1) What factors are associated with increased risk of unsatisfactory pain management following orthopaedic surgery? (2) What are the key components of successful pain management protocols following orthopaedic surgery?

PRISMA guidelines were followed with a search of relevant online databases. Studies were included if they were in English, provided patient feedback/satisfaction with pain management (quantitative studies) or provided satisfaction with pain management or healthcare team feedback (qualitative studies) or explored patient variables associated with satisfaction with pain management.

Of the 845 articles screened, 27 met the inclusion criteria. Synthesis suggested that while perceived severity and duration of pain are often assumed to be the primary drivers of patient satisfaction related to pain management, patients with a sense of control over their pain reported higher satisfaction, regardless of actual pain level. History of opioid misuse, patient expectations, and patient mental health were associated with dissatisfaction.

Pre-operative education and ongoing communication, particularly regarding patient risk-factors and multi-modal pain management strategies, appear to enhance patients' sense of control and satisfaction. Future research should explore whether individualised pre-operative education can improve satisfaction with post-surgical orthopaedic pain management.
