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

purposeTo describe postdischarge opioid dispensing after Cesarean delivery (CD) in 49 hospitals in British Columbia (BC) and assess opportunities for opioid stewardship.

methodsUsing the BC Ministry of Health's Hospital Discharge Abstract Database, we linked 135,725 CDs performed in 2004-2016 and 30,919 CDs performed in 2017-2019 (length of stay ≤ four days) by deidentified Personal Health Numbers to data on medications dispensed from all BC community pharmacies (PharmaNet). We excluded patients with cancer and those to whom opioids have been dispensed in the year before. We measured trends in annual percentages of patients dispensed opioids within seven days (opioid rate), with 95% confidence intervals (CIs), stratified by hospital and opioid type, adjusted for length of stay, and for autocorrelation within hospital using generalized linear modeling.

resultsThe opioid dispensation rate dropped from 31% (95% CI, 30 to 33) in 2004 to 16% (95% CI, 15 to 17) in 2016, where it remained through 2019. Five hospitals showed steep reductions from over 40% to under 10% within two to three years, but in most hospitals the opioid dispensation rate decreased slowly-11 had little reduction and three showed increases. Codeine dispensing dropped from 31% in 2004-2008 by 4% per year, while tramadol and hydromorphone dispensing rose. After 2015, rates were stable (hydromorphone, 8%; tramadol, 6%; codeine, 3%; and oxycodone, 0.5%).

conclusionAfter Health Canada's 2008 warning against codeine use by breastfeeding mothers, post-CD opioid dispensing declined disjointedly across BC hospitals. Rates did not decrease further after the opioid overdose epidemic was declared a public health emergency in BC in 2016. The present study highlights opportunities for quality improvement and opioid stewardship through monitoring using administrative databases.
