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.

2 · The registry

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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectiveTo identify patient factors and health care utilization patterns associated with dose escalation during the first year of long-term opioid therapy for chronic pain.

designRetrospective cohort study using electronic health record data.

settingUniversity health system. SUBJECTS: Opioid naïve adults with musculoskeletal pain who received a new outpatient opioid prescription between July 1, 2011 and June 30, 2012 and stayed on opioids for 1 year.

methodsMixed-effects regression was used to estimate patients' rate of opioid dose escalation. Demographics, clinical characteristics, and health care utilization for patients with and without dose escalation were compared.

resultsTwenty-three (9%) of 246 patients in the final cohort experienced dose escalation (defined as an increase in mean daily opioid dose of ≥30-mg morphine equivalents over 1 year). Compared with patients without dose escalation, patients with escalation had higher rates of substance use diagnoses (17% vs 1%, P = 0.01) and more total outpatient encounters (51 vs 35, P = 0.002) over 1 year. Differences in outpatient encounters were largely due to more non face-to-face encounters (e.g., telephone calls, emails) among patients with dose escalation. Differences in age, race, concurrent benzodiazepine use, and mental health diagnoses between patients with and without dose escalation were not statistically significant. Primary care clinicians prescribed 89% of opioid prescriptions.

conclusionsDose escalation during the first year of long-term opioid therapy is associated with higher rates of substance use disorders and more frequent outpatient encounters, especially non face-to-face encounters.
