Clinical Trial Summary

This pilot-feasibility study of a cluster parallel randomized design comparing CBT-i against usual care (UC) was performed at two primary health care centers in Majorca, Spain. Patients were included if they were 18 to 65 years-old; had diagnoses of chronic insomnia according to the Insomnia Severity Index (ISI more than 8) and had insomnia longer than 3 months; and did or did not use a hypnotic medication. 25 GPs and nurses and 32 patients were randomly allocated to two groups: The outcome of the trial was improving the quality of sleep. Other primary outcomes on feasibility and applicability of the intervention were collected through nominal groups. Description of usual care was described through previous studies. Moreover we assessed recruitment process, compliance with the intervention sessions, and patient's retention.

Objectives

The primary objectives of this pilot-feasibility study were:

1. To design and adapt a brief CBT-i intervention to be provided by PCPs for the treatment of chronic insomnia in individuals who are 18 to 65 years-old.

2. To define usual care (UC) for the treatment of chronic insomnia provided by PCPs as a comparative intervention (control group).

3. To assess the training activities for the CBT-i intervention by determining GPs' and nurses' satisfaction with the content and applicability of the intervention.

4. To determine the acceptability of the intervention by GPs and nurses.

5. To assess PCPs and patient recruitment, follow-up, and adherence to the intervention The secondary objective was to assess the quality of sleep in patients after 3 months of the CBT-i.

Methods Design This pilot-feasibility study of a cluster parallel randomized design comparing CBT-I against usual care (UC) was performed from September 2014 to April 2015 at two primary health care centers of Majorca (Spain) with 56,000 registered inhabitants.

Collection of information and follow up Intervention The CBT-i intervention was developed by two family physicians (IT and CV) and two psychologists (ET and MRP-P). First, a review of the literature on the use of CBT-i was performed, with a focus on interventions applied in primary care. After the literature review, the CBT-i created by Morin [24] was adapted to our setting, in which there were fewer sessions and shorter sessions. The CBT-i included sleep hygiene counseling, stimulus control, cognitive restructuring, relaxation techniques, and benzodiazepine therapy or withdrawal (when needed). To conduct the intervention, guidelines for GPs and nurses and graphic and written materials for patients (sleep diary, registry of behavior habits, and cognitive problems) were developed.

Usual care The usual treatment for persistent insomnia in a primary care setting was previously described in two cross-sectional studies performed by general practitioners and family nurses of the Primary Care Majorca Department during 2011 and 2015

Outcome

Type Measure Description Time frame Safety issue
Primary Acceptability of the training of PCPs Satisfaction with training content and its ability to provide sufficient training measured though 2 nominal groups with a previous script 3 months postintervention
Secondary Feasibility of the intervention Adequacy of sessions in terms of content, duration and number, fitting in PCPs agenda and patients acceptance. 3 months postintervention
Secondary Feasibility of the study design Number of patients eligible identified and included, number of PCP randomized, number of patients followed up,completion of follow up and adherence to intervention sessions. 3 months postintervention
Secondary Intervention Effectiveness: Sleep The Pittsburgh Sleep Quality Index (PSQI) is a 19-items self reported questionnaire that assesses 7 clinical components of sleep quality. Each item is rated on 0 to 3 point scale in which 0 is equal to not in the past month and 3 is equal to 3 or more times a week, with a global score range from 0 to 21. A cut off score of 5 has shown to discriminate between good and bad sleepers. pretreatment and 3 months postintervention
Secondary Intervention Effectiveness:Anxiety The Hospital Anxiety and Depression Scale (HADS) measures anxiety and depression levels in the preceding week. It is 14-item self-report scale with two 7-item anxiety or depression subscales. Each item scores from 0 to 3 point scale giving maximum subscale scores of 21. Patients with scores >10 are considered to have morbidity, between 8 and 10 as borderline cases and <8 absence of relevant pretreatment and 3 months postintervention
