Health and well-being of mothers and co-parents during the first 12 months post partum: study protocol of the national SOCRATES cohort study in Switzerland
Article excerpt
Introduction The first year after childbirth is a critical yet insufficiently monitored period for parental health. Postpartum mental and physical morbidity can affect both mothers and co-parents, but national longitudinal data remain scarce. The Stress Of Co-parents Related to A…
Objective To summarise the evidence on long-term and infrequent harms following selected spinal and paraspinal injections and denervation procedures for chronic non-cancer spine pain.
Design Systematic review and meta-analysis.
Data sources MEDLINE, EMBASE and Cumulative Index to Nursing and Allied Health Literature from inception to October 2023.
Study selection Non-randomised studies reporting on harms of selected interventional procedures administered to adults living with chronic axial or radicular non-cancer spine pain with ≥4 weeks of follow-up.
Data extraction and synthesis A parallel guideline panel provided input on the scope, design and interpretation of this systematic review, including selection of adverse events for consideration. Systematic literature screening, data abstraction and risk of bias appraisal were conducted independently and in duplicate by pairs of reviewers. We used random-effects models for all meta-analyses and the Grading of Recommendations Assessment, Development and Evaluation approach to evaluate the certainty of evidence.
Results We included 60 longitudinal studies (56 non-comparative, 4 comparative) that enrolled 4966 patients with chronic non-cancer spine-related pain. 31 studies investigated radiofrequency ablation or denervation, 22 epidural injections and 11 joint injections or nerve blocks. Low certainty evidence suggests that joint targeted steroid injection and epidural steroid injection for chronic spine pain may result in temporary altered level of consciousness (incidence: 2.1%; 95% CI 1.1% to 4.0%), joint radiofrequency nerve ablation, joint targeted steroid injection and epidural injection of local anaesthetic and steroids may result in deep infection (incidence: 0.7%; 95% CI 0.3% to 2.0%), epidural steroid injection, joint radiofrequency nerve ablation and joint targeted injection of local anaesthetic and steroids may result in dural puncture (incidence: 1.4%; 95% CI 0.5% to 4.3%), and dorsal root ganglion radiofrequency and joint radiofrequency nerve ablation with or without joint-targeted injection of steroids may result in prolonged pain or stiffness (incidence: 8.6%; 95% CI 6.3% to 11.6%). Several interventional procedures may result in metabolic complications and prolonged sensory deficits, but the supporting evidence was only very low certainty. Most complications resolved spontaneously or with conservative management.
Conclusions Low certainty evidence suggests that several common interventional procedures for chronic spine pain show risk of deep infection, dural puncture, temporary altered level of consciousness and prolonged pain or stiffness. Other harms are uncertain due to very low certainty evidence, and catastrophic outcomes were not reported in the small studies that contributed to our analyses.
