Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if training primary care providers on treatment of insomnia can improve insomnia symptoms in patients. Researchers will compare insomnia symptoms of patients receiving care from trained practices with patients receiving care from control practices (providing care-as-usual), to see if the training helps to provide improved insomnia care. Participants will be asked to complete four questionnaires and some participants will be invited for an insomnia consultation in primary care by their primary care providers (PCP).

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The cluster randomization trial involves two randomization procedures. Firstly, on primary care practice level, practices will be randomized to intervention practice or control practice. Secondly, patients in the intervention practices will be randomized to pro-active identification or no identification. Pro-actively identified insomnia patients will be reported back to the PCP.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Training with pro-active identification

For detailed description of the intervention, see the separate section on interventions.

Group Type EXPERIMENTAL

Training

Intervention Type OTHER

A 4-hour training for PCPs consisting of an onsite training, an e-learning and a webinar on the treatment of insomnia.

Pro-active identification

Intervention Type OTHER

Pro-active identification of patients with clinical insomnia symptoms. Patients receiving care from the participating practices will be asked to fill-out the Insomnia Severity Index (ISI).The ISI is used to identify patients with clinical insomnia symptoms in the general practice. Trained practices will receive feedback on the ISI for half of the patients with clinical symptoms according to the ISI.

Training without pro-active identification

For detailed description of the intervention, see the separate section on interventions.

Group Type EXPERIMENTAL

Training

Intervention Type OTHER

A 4-hour training for PCPs consisting of an onsite training, an e-learning and a webinar on the treatment of insomnia.

Control

Care as usual according to national applicable primary guide guidelines.

Group Type NO_INTERVENTION

No interventions assigned to this group
