Short communication: Do clinical guidelines for bipolar disorders adequately address sleep, circadian rhythm,...

Objectives Clinical practice guidelines (CPGs) for the treatment of bipolar disorder (BD) provide guidance to health care professionals and patients about the management of core aspects of BD. This study evaluated the overall quality of CPGs and examined the quantity, specificity, clarity and utility of recommendations about four key contemporary themes: sleep, circadian rhythms, activity and energy, and healthy lifestyles. Methods English language editions of CPGs for the treatment of BD were identified by a systematic search of the literature from 2007 onwards (i.e. 15 years). Blind independent ratings were combined to give consensus scores for the quality of each CPGs (using the 14-item International Center for Allied Health Evidence guideline checklist). Composite ratings of the quantity, specificity, clarity and utility of recommendations about the key themes were undertaken using a 0-3 scale. Results Twenty-five CPGs were eligible for review. Overall quality was high (median checklist score=10), but only 11 (44%) CPGs included even basic information about circadian rhythm disturbances. Combined scores for composite ratings about sleep and circadian rhythms were significantly correlated with overall quality of the CPG (sleep, r = 0.43; circadian rhythms, r = 0.42) but not with year of publication. Limitations No reliable scale exists for generating composite ratings of the four themes we examined. Conclusions Circadian rhythms and chronobiology represent neglected domains in CPGs. Incorporating this important theme into future editions of CPGs would aid health care professionals to identify, prevent, or intervene with these problems and improve outcomes for a significant proportion of individuals with BD.
