Brief summary
Randomized controlled trial to evaluate effectiveness of behavioral Brief Intervention administered by General practitioners (GPs) versus business as usual on use of Z-hypnotics by elderly patients in primary care.
Detailed description
Two armed study with controlled masked first part over 6 months. Active arm is with Brief Intervention for inappropriate use of Z-hypnotics among elderly with intervention delivered by trained GPs. Control arm is for patients handled by their (non-trained) GPs with business as usual (BAU). Main outcome is 6 weeks after intervention with additional data collection points after 6 months (blinded) and long-term follow-up to 12 months (open). After 6 months there will be an open single crossover as BAU GPs will then also receive training in the Brief Intervention method. Baseline assessments are limited to self reports and automatic sleep assessment with actigraphy to avoid assessment effects. Follow-up at main outcome time point is in person, some outcomes are also by telephone assessment and compared to baseline prior to intervention (e g Actigraphy assessment.
Interventions
Short structured individual behavioral intervention to reduce inappropriate usage of Z-hypnotics
Sponsors
Study design
Masking description
GPs will be cluster randomized based on GP to two sequential teaching programs to learn the Brief Intervention procedure. The patients of those who have the course first will constitute the intervention arm while patients of GPs who are in the second course will constitute parallel business as usual controls in the masked part of the study. When the second group of GPs have their course, open cross-over will be possible.
Intervention model description
Parallel masked and controlled first part intervention vs Business as usual with follow-up after 6 months by masked assessors. Subsequently open single cross-over of business as usual patients to also receive the same intervention.
