Chronic pain substantially impacts patient function and quality of life and is a burden to society at large in terms of increased health care utilization and loss of productivity. As a result, there is an increasing recognition of chronic pain as a public health crisis. However, there remains wide variability in clinical practices related to the prevention, assessment, and treatment of chronic pain. Certain fundamental aspects of chronic pain are often neglected including the contribution of the psychological, social, and contextual factors associated with chronic pain. Also commonly overlooked is the importance of understanding the likely neurobiological mechanism(s) of the presenting pain and how they can guide treatment selection. Finally, physicians may not recognize the value of using electronic medical records to systematically capture data on pain and its impact on mood, function, and sleep. Such data can be used to monitor onset and maintenance of treatments effects at the patient level and evaluate costs at the systems level. In this review we explain how these factors play a critical role in the development of a coordinated, evidence-based treatment approach tailored to meet specific needs of the patient. We also discuss some practical approaches and techniques that can be implemented by clinicians in order to enhance the assessment and management of individuals with chronic pain in primary care settings.
ARTICLE HISTORY
Osteoarthritis (OA) is a common difficult-to-treat condition where the goal, in the absence of diseasemodifying treatments, is to alleviate symptoms such as pain and loss of function. Acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), and opioids are common pharmacologic treatments for OA. Antibodies directed against nerve growth factor (NGF-Abs) are a new class of agents under clinical investigation for the treatment of OA. This narrative review describes (and uses schematics to visualize) nociceptive signaling, chronification of pain, and the mechanisms of action (MOAs) of these different analgesics in the context of OA-related pain pathophysiology. Further, the varying levels of efficacy and safety of these agents observed in patients with OA is examined, based on an overview of published clinical data and/or treatment guidelines (when available), in the context of differences in their MOAs.
Fibromyalgia (FM) is a complex chronic disease that affects 3-10% of the general adult population and is principally characterized by widespread pain, and is often associated with disrupted sleep, fatigue, and comorbidities, among other symptoms. There are many gaps in our knowledge of FM, such that, compared with other chronic illnesses including diabetes, rheumatoid arthritis, and asthma, it is far behind in terms of provider understanding and therapeutic approaches. The experience that healthcare professionals (HCPs) historically gained in developing approaches to manage and treat patients with these chronic illnesses may help show how they can address similar problems in patients with FM. In this review, we examine some of the issues around the management and treatment of FM, and discuss how HCPs can implement appropriate strategies for the benefit of patients with FM. These issues include understanding that FM is a legitimate condition, the benefits of prompt diagnosis, use of non-drug and pharmacotherapies, patient and HCP education, watchful waiting, and assessing patients by FM domain so as not to focus exclusively on one symptom to the detriment of others. Developing successful approaches is of particular importance for HCPs in the primary care setting who are in the ideal position to provide long-term care for patients with FM. In this way, FM may be normalized as a chronic illness to the benefit of both patients and HCPs.
The purpose of this narrative review is to provide a brief high-level overview of NeP for primary healthcare providers that includes a discussion of mechanisms, prevalence, burden, assessment, and treatment. The information provided here should help primary care providers better understand this type of chronic pain.
