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

backgroundOpioid overdose epidemic is hitting record highs worldwide, accounting for 76% of mortality related to substance use. Take-home naloxone (THN) strategies are being implemented in many developed countries that suffer from high opioid overdose death rates. They aim to provide overdose identification and naloxone administration training, along with THN delivery to opioid users and others likely to witness an overdose incident such as family members and peers. However, little is known about such measures in low- and middle-income countries (LMIC), where opioid use and opioid-related deaths are reportedly high. This systematic literature review aims to examine the distribution of THN in LMIC, review studies identifying barriers to the implementation of THN programs worldwide, and assess their applicability to LMIC.

methodsThe literature was searched and analyzed for eligible studies with quality assessment.

resultsTwo studies were found from LMIC on THN programs with promising results, and 13 studies were found on the barriers identified in implementing THN programs worldwide. The main barriers to THN strategies were the lack of training of healthcare providers, lack of privileges, time constraints, cost, legislative/policy restrictions, stigma, fear of litigation, and some misperceptions around THN.

conclusionsThe barriers outlined in this paper are probably applicable to LMIC, but more difficult to overcome considering the differences in their response to opioid overdose, their cultural attitudes and norms, the high cost, the waivers required, the legislative differences and the severe penalties for drug-related offenses in some of these countries. The solutions suggested to counter-act these obstacles can also be more difficult to achieve in LMIC. Further research is required in this area with larger sample sizes to provide a better understanding of the obstacles to the implementation, feasibility, accessibility, and utilization of THN programs in LMIC.
