Androgen Deprivation and Sleep Disturbance: A Mixed Methods Pilot Study of Remote Assessment and Intervention.

ABSTRACT

BACKGROUND: Men receiving androgen deprivation therapy (ADT) for prostate cancer (PC) are at risk for cardiovascular comorbidities and cognitive changes. Interventional research involves in-person assessment of physical fitness/activity and cognitive function, which has been negatively affected by the COVID-19 pandemic. Androgen deprivation therapy-related hot flashes and nocturia increase risk for insomnia. Insomnia is associated with fatigue and may exacerbate ADT-related cognitive changes. OBJECTIVES: The purpose of this mixed-methods pilot was to (1) determine feasibility/acceptability of remotely assessing physical fitness/activity, cognitive function, and sleep; (2) deliver telehealth cognitive behavioral training for insomnia (teleCBT-I) to improve sleep; and (3) garner qualitative feedback to refine remote procedures and teleCBT-I content. METHODS: Fifteen men with PC receiving ADT completed a 4-week teleCBT-I intervention. Videoconferencing was used to complete study assessments and deliver the weekly teleCBT-I intervention. RESULTS: Self-report of sleep quality improved (P < .001) as did hot flash frequency (P = .04) and bother (P = .025). Minimal clinically important differences were detected for changes in insomnia severity and sleep quality. All sleep logs indicated improvement in sleep efficiency. Remote assessment of fitness/cognitive function was demonstrated for 100% of participants. Sufficient actigraph wear time allowed physical activity/sleep assessment for 80%. Sleep actigraphy did not demonstrate significant changes. CONCLUSIONS: Remote monitoring and teleCBT-I are feasible/acceptable to men with PC on ADT. Further research to confirm teleCBT-I efficacy is warranted in this population. IMPLICATIONS FOR PRACTICE Preliminary efficacy for teleCBT-I interventions was demonstrated. Remote assessments of physical fitness/activity, sleep, and cognitive function may enhance clinical trial access for rural or economically disadvantaged PC survivors.
