ObjetiveTo evaluate the effectiveness of providing an educational intervention in primary care (PC) alongside a pharmacological treatment for insomnia.DesignSingle blinded non randomised clinical trial.LocationTwo urban primary health centers in Gijón (Asturias, Spain).ParticipantsPatients who consulted for insomnia between July 2012-January 2013 and met the inclusion criteria (n=50) were assigned systematically to the control group (CG) or intervention group (IG). All patients initiated treatment with lorazepam 1mg in the evenings and had four weekly 15 min visits plus a follow-up visit after another month.InterventionsThe IG received training for control of stimuli, sleep hygiene and respiration and relaxation techniques in the four visits. The CG had only non invasive measures taken.MeasurementsConsidering as cured those who reached a Pittsburgh Sleep Quality Index PSQI <6 or a 50% reduction from baseline level. It was also analyzed the change in the PSQI from baseline to final visit and to follow-up visit, and voluntary interruption of lorazepam. Analysis by Bayesian inference.ResultsTwelve out of recoveries after intervention against one out of 24 among control group. Mean change in PSQI to final visit and follow-up visit was: -4.7 (95%CrI:-5.9 to -3.5) and -6,3 (95%ICred: -7.5 to -5.1) in IG; -1.8 (95%ICred: -3 to -0.5) and -1.7 (95%ICred: -2.9 to -0.4) in CG. Interruption of lorazepan: in 4 controls (16,7%) and 9 (34,6%) in IG. Twenty nine patients in GI and 17 in GC completed the trial. Per protocol analysis showed similar results.ConclusionsThe educational intervention in PC improves sleep quality and reduces the need of treatment with benzodiacepines.Copyright © 2013 Elsevier España, S.L.U.
