The primary outcome was days to resolution of concussive symptoms, defined as a PCSS score ≤ 3. The median baseline PCSS score was 21 in the screen time–permitted group and 24.5 in the screen time–abstinent group. The screen time–permitted group reported a median screen time of 630 minutes during the intervention period, compared with 130 minutes in the screen time–abstinent group, and was less likely to recover during the study period than the screen time–abstinent group (hazard ratio = 0.51; 95% CI, 0.29-0.90). The screen time–permitted group had a significantly longer median recovery time compared with the screen time–abstinent group (8.0 vs 3.5 days; P = .03).
WHAT'S NEW?
Exploring the role of screen time during the cognitive rest period
This study provides evidence supporting the recommendation that adolescent and young adult patients abstain from screen time in the first 48 hours following a concussion to decrease time to symptom resolution, thus shortening the timeline to return to their usual daily activities.
CAVEATS
Self-reporting of data may introduce bias
This study used a self-reporting method to collect data, which could have resulted in underreporting or overreporting of screen time and potentially introduced recall and reporting bias. The screen time–abstinent group did not completely abstain from all screen time, with a self-reported average of 5 to 10 minutes of daily screen time to complete the required research surveys, so it is not immediately clear what extent of abstinence vs significant screen time reduction led to the clinical endpoints observed. Furthermore, this study did not ask patients to differentiate between active screen time (eg, texting and gaming) and passive screen time (eg, watching videos), which may differentially impact symptom resolution.
CHALLENGES TO IMPLEMENTATION
Turning off the ever-present screen may present obstacles
This intervention is easy to recommend, with few barriers to implementation. It’s worth noting that screens are often used in a patient’s school or job, and 48 hours of abstinence from these activities is a difficult ask when much of our society’s education, entertainment, and productivity revolve around the use of technology. When appropriate, a shared decision-making discussion between patient and physician should center on the idea that 48 hours of screen time abstinence could be well worth the increased likelihood of total recovery at Day 10, as opposed to the risk for persistent and prolonged symptoms that interfere with the patient’s lifestyle.
