Managing Chronic Pain: A Challenge for Modern Healthcare

Introduction: Chronic pain is a major global public health issue, affecting an estimated 20% of adults worldwide. Prevalence is particularly high among the elderly and those in long-term care. In Poland, up to 30% of adults are affected, with even higher rates observed among institutionalized populations. Osteoarthritis is the most frequent cause, accounting for over one-third of cases. Despite ongoing medical advances, effective management of chronic pain remains a major clinical challenge due to its multifactorial etiology and high interindividual variability. Aim: This narrative review aims to provide a comprehensive and integrative summary of current knowledge on chronic pain, including its pathophysiological mechanisms, classification, and modern management strategies. Particular attention is given to pharmacological and non-pharmacological approaches, with an emphasis on the role of individualized, interdisciplinary care in improving patient outcomes. Methods: A narrative literature review was conducted using PubMed and Google Scholar. The search prioritized large cohort studies, systematic reviews, meta-analyses, and recent mechanistic investigations. Studies addressing both pharmacological and non-pharmacological methods of chronic pain management were selected based on scientific relevance and evidence quality. Results: Pharmacological treatment includes nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, antidepressants, and anticonvulsants, although their use is often limited by adverse effects and reduced long-term efficacy. Non-pharmacological interventions such as physiotherapy, psychotherapy, relaxation techniques, neuromodulation, and lifestyle modification play a crucial role in improving patient quality of life and functional status. An individualized treatment plan based on a biopsychosocial model is considered the most effective approach. Conclusions: Chronic pain management requires personalized, interdisciplinary strategies aimed not solely at symptom relief but at enhancing daily functioning and well-being. Improved access to comprehensive pain services and increased awareness among healthcare professionals and patients are essential for optimizing outcomes.
