Despite guidelines on ultraviolet (UV) avoidance, it remains difficult for people to assess their exposure, as UV is invisible and the onset of UV-induced symptoms is delayed.  \nMethods: In a prospective randomized trial, 97 elderly patients with a history of actinic keratoses (AK) were followed over 6 months. Fifty patients received UV counseling from a dermatologist and a wearable UV dosimeter that provided real-time and cumulative UV exposure. Forty-seven patients received only UV counseling from a dermatologist.  \nResults: Over 75% of participants recorded UV exposure at least once a week during the summer. After 6 months of intervention, when comparing the device group to the control group, we observed a non-significant 20% lower ratio of incidence rates of AKs (95% CI = [−41, 55%], p-value = 0.44) and a significant 95% lower ratio of incidence rates of NMSCs (95% CI = [33, 99.6%], p-value = 0.024) . Surveys demonstrated that the control group’s score in self-perceived ability to participate in social activities significantly increased by 1.2 (p-value = 0.04), while in the device group, this score non-significantly decreased by 0.9 (pvalue = 0. 1) . We did not observe changes, or between-group differences, in anxiety and depression surveys.  \nConclusion: This pilot clinical trial has a short duration and a small sample size. However, device adherence and quality of life questionnaires suggest a smartphone-connected wearable UV dosimeter is well accepted by an elderly population. This trial also indicates that a wearable UV dosimeter may be an effective behavioral change tool to reduce NMSC incidence in an elderly population with a prior history of AKs.  \n[Clinical trial registration](Clinical trial registration: clinicaltrials.gov)[:](Clinical trial registration: clinicaltrials.gov)[ clinicaltrials.gov](Clinical trial registration: clinicaltrials.gov), identifier NCT03315286 .  \nKEYWORDS  \nskin cancer, basal cell carcinoma,","cbCaihjKUQPSHuEO","https://ap.wps.com/l/cbCaihjKUQPSHuEO","pdf",2364727,"English","# Background\n# Methods\n# Results\n# Conclusion","[{\"question\":\"What problem does the trial address regarding UV exposure?\",\"answer\":\"UV is invisible and UV-related symptom onset is delayed, making personal UV exposure hard to assess even with avoidance guidelines.\"},{\"question\":\"How was the study designed and who participated?\",\"answer\":\"In a prospective randomized trial, 97 elderly patients with a history of actinic keratoses were followed over 6 months and assigned to a device group or a counseling-only control group.\"},{\"question\":\"What were the main findings after 6 months?\",\"answer\":\"Compared with control, the device group showed a non-significant 20% lower AK incidence rate ratio and a significant 95% lower NMSC incidence rate ratio; anxiety and depression surveys did not change between groups.\"}]","A randomized trial of a wearable UV dosimeter for skin cancer prevention | PDF",1790019667,23]
