Article in Journal of palliative medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03161795 (Addressing the Risks of Long-Term Opioid Therapy in Chronic Noncancer Pain), which is not on this map. Cited by 23 papers.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Abstract

background"Chemical coping" is a commonly used term in the pain and palliative care literature, but is heterogeneously defined. We conducted a Delphi survey among palliative care and pain specialists internationally to identify a consensus definition for "chemical coping with opioids" and warning signs for chemical coping.

methodsThis Delphi survey consisted of two rounds on the following: (1) concepts and definition related to chemical coping, (2) warning signs for chemical coping, and (3) demographics. Consensus in this study was defined as agreement by a minimum of 70% of the experts.

resultsParticipating in the first round were 14/19 (74%) physicians; 12/14 (86%) participated in the second round. The international experts reached the following consensus definition for chemical coping with opioids (92% agreement): "The use of opioids to cope with emotional distress, characterized by inappropriate and/or excessive opioid use." They also identified depression (consensus 93%); psychiatric disease (86%); a history of substance abuse (86%); a positive score for the Cut-down, Annoyed, Guilty, and Eye-opener (CAGE) alcoholism screening test (79%); a history of alcoholism (79%); and a history of smoking (71%) as important warning signs for chemical coping.

conclusionOur expert panel reached a consensus definition for chemical coping and related warning signs, which may help clinicians and researchers to identify patients at risk of opioid misuse.
