The Special Interest Group on digital interventions of the International Network on Brief Interventions for Alcohol & Other Drugs (e-INEBRIA SIG) was launched at the INEBRIA conference in Lausanne (2016); the group also took part in INEBRIA conferences in 2017 (New York) and 2018 (Santiago de Chile). During the conference in Santiago de Chile, e-INEBRIA SIG discussed possible avenues for further research that subsequently, in continued meetings, turned into a roadmap, as presented in this commentary. In particular, e-INEBRIA SIG is interested in the potential of electronic health (eHealth) technologies for brief interventions in health and other settings to reduce the harms produced by alcohol, drug use, and gambling.

There is great potential for scaling up the delivery of brief interventions, given the increasing coverage in high, middle, and low income countries of smartphones, wearables, and other connected devices worldwide, and the rise of new technologies like geotagging and chatbots. Knowing which technologies can be successfully applied in target groups of alcohol and drug users and which components of interventions are essential for reducing harm could help enhance their impact at a public health level.

One strategy to foster evidence-based developments is to keep track of ongoing scientific developments, including periodic reviews and meta-analyses on the effectiveness and implementation of internet interventions for alcohol and other substances. Recent meta-analyses have demonstrated the effectiveness of internet interventions at reducing alcohol use in alcohol misusers [1]; reducing cannabis use in cannabis misusers, at least in the short-term [2]; and reducing drug use among opioid and mixed-drug users [3]. Moreover, individual patient data (IPD) meta-analyses could, due to their large pooled samples, help to identify initial trends in subgroups (eg, [1]).

However, a limitation of most digital interventions developed as part of scientific studies is that they often lack funding for maintenance after study completion. A recent review on such interventions in the alcohol field identified 72 trials assessing alcohol interventions, among which only 8 (11%) remained accessible; these were mostly internet-based interventions [4].

While numerous digital interventions aiming to reduce substance use are available, most lack evidence-based brief intervention content, have never been evaluated for effectiveness, and have been developed without academic or specialist input, including some that are profit-oriented [5,6]. In the case of cannabis misuse, the situation is worse because the few genuine apps aimed at harm reduction and reducing cannabis use are forced to compete with hundreds of currently available apps that promote cannabis use [7]. Some attempts have been made to develop evidence-based health app quality rating scales, and one has been developed for researchers [8], with a version available for end users [9]; however, it is unlikely that alcohol and drug users make use of the latter. Thus, it is rational to foster research on genuine harm-reduction–oriented digital interventions, particularly apps, to promote their use and evidence-based quality development.

While it is rational to develop generalizable digital interventions to reduce harm from alcohol and drug use at a general population level, there is evidence from other mental health fields that tailored digital interventions for specific cultures or migrants [10] can increase their effectiveness. There are few systematic reviews of tailored digital interventions for specific alcohol- or drug-using groups and classical diversification topics (eg, different age groups, like the elderly, as well as different genders, educational levels, and cultures). The development of such digital interventions in the addiction field is still in its infancy relative to face-to-face interventions.

While this roadmap provides orientation to current developments in this field, it is also considered a starting point. It will need updating and ongoing promotion at future meetings and conferences, as well as in publications. Moreover, we must ensure that the points listed in our roadmap will be followed by actions. Therefore, we plan to continue our discussions between future INEBRIA conferences, during symposia and workshops at these conferences, and at related conferences like those of the International Society for Research on Internet Interventions (ISRII) and the International Society of Behavioral Medicine (ISBM), where alcohol and drug use can be linked to relevant developments in digital interventions (ISRII), epidemiology, and interventions for health-related behaviors and chronic conditions (ISBM).

The roadmap proposed by e-INEBRIA SIG on digital interventions is a starting point that indicates relevant next steps. It also provides orientation for researchers and interested practitioners with regard to the ambiguous literature and the complexity of current digital interventions. Moreover, it is a call for action to coordinate our efforts toward research and evidence-based implementation in the context of rapid technological development.
