Study description

CARE is a non-interventional, retrospective analysis of depersonalized data from the German Pain e-Registry, in which routine data from everyday care are used to evaluate the efficacy and tolerability of cannabis-based medications in older adults with intractable pain.
The primary characteristic of the treatment documentation is the prescription of CBD-rich (i.e. CBD content > THC content) oral extracts or dronabinol/THC for the treatment of therapy-resistant ± chronic pain within the scope of the Glaw to amend narcotics and other regulations (§ 31 (6) SGB V) and the use of the online documentation software iDocLive® for standardized observation of the course of treatment in accordance with usual care standards.
As the treatment-justifying indication for the present evaluation, both parties agree on the presence of pain that is difficult to treat by other means (in accordance with the legal requirements for the use of cannabis-based drugs).
To ensure comparable baseline findings, a so-called propensity score matching (PSM) is carried out, in which each patient treated with dronabinol/THC is matched with a patient treated with a CBD-rich oral extract [with regard to age, sex, pain phenotype, duration of illness, severity of impairment, chronicity stage and analgesic co-medication (ATC group)] comparable patient is assigned to each patient treated with dronabinol/THC in a so-called “1:1 matching” (caliper 0.15, “without replacement”).
All analyses are exploratory. The primary endpoint is the absence of treatment discontinuation due to an ADR in conjunction with clinically relevant relief of pain and pain-related impairments in daily life (each with an improvement of at least 20 mm VAS and/or 30% vs. BL).
