[General practice care for patients with chronic non-cancer pain: A rapid review as part of the RELIEF project]

Introduction: Approximately one fifth of the German population suffers from chronic pain, which is often associated with limitations in coping with everyday life, social isolation and psychological comorbidities such as anxiety and depression. The importance of a treatment approach that considers biological, psychological, and social factors (bio-psycho-social model) as well as non-drug interventions is emphasized in current guidelines, but presents challenges for primary care practices. To support the implementation of evidence-based best practice recommendations, the RELIEF project (Resource-oriented case management to implement recommendations for patients with chronic pain and frequent use of analgesics in general practices) aims to develop a case management program for the primary care of patients with chronic non-tumor pain.

Methods: Prior to intervention development, a rapid review was conducted to identify best practice recommendations for the care of patients with chronic non-tumor pain, barriers and strategies to their implementation, and gaps in care in current guidelines and literature. Selective searches of guidelines, PubMed, the Cochrane Library, bibliographies of relevant publications, and the gray literature focused on assessment and monitoring, education, promotion of self-care, and rational pharmacotherapy.

Results: Numerous recommendations on assessment and monitoring were identified, but only a few studies examined their feasibility in primary care practices. Guidelines contained few specific recommendations on content and format of patient education on chronic pain. Recommendations for non-drug self-care measures were mainly related to physical activity, relaxation techniques, behavioral therapy techniques and external applications. Especially for the area of physical activity, numerous barriers but also strategies for a successful implementation could be identified.

Discussion: In a potential primary care model for patients with chronic non-tumor pain, pain assessment should aim to identify patients who need support in implementing medication and non-medication interventions in the primary care setting and/or could benefit from specialized care. To implement recommendations for pain education, primary care physicians need educational materials in a variety of formats and levels of detail that ideally could be processed by patients at home and then get addressed in practices using simple key questions. Non-drug measures should be an explicit part of the treatment plan.

Conclusion: Many of the identified recommendations for the treatment of patients with chronic non-tumor pain can also be considered relevant for the primary care setting. Specific guidelines and concepts for primary care physicians that include setting-specific characteristics at the physician, patient, and system levels would be desirable for a successful implementation of these recommendations.
