Hilmisson H, Sveinsdottir E, Lange N, Magnusdottir S. Insomnia symptoms in primary care: A prospective study focusing on prevalence of undiagnosed co-morbid sleep disordered breathing. Eur J Intern Med 2019; 63: 19-26. DOI: 10.1016/j.ejim.2019.01.011
To determine prevalence of comorbid undiagnosed sleep disordered breathing (SDB) in chronic insomnia patients, using two complementary methods, one standard (Home Sleep Apnea Test; HSAT) and one novel (CadioPulmonary Coupling; CPC).
High prevalence and overlap in symptoms between insomnia and SDB warrants objective testing when evaluating sleep complaints before therapy is initiated. Diagnostic caution is even more importantly warranted for female patients presenting insomnia sleep complaints, as SDB may not be initially considered as a biological symptom driver.
CPC-analysis is simple and low-cost method that can serve as a standalone option to evaluate sleep complaints in individuals presenting insomnia symptoms before therapy is initiated.
