NCT06575998

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • Change in patient reported insomnia symptoms using the Insomnia Severity Index (ISI)

    Change is measured linearly using the Insomnia Severity Index. Scores range from 0 to 28 points in which higher scores represent a worse outcome. Secondly, the categorically defined treatment response is established 2 months after baseline questionnaire (remission = ISI score \< 11, ISI score reduction ≥ 8).

    From baseline to measurements at 2, 6 and 12 months

Secondary Outcomes (6)

  • Patient reported non-pharmacological 'sleep consultation'

    12 months after baseline questionnaire

  • Report by the PCP of a non-pharmacological 'sleep consultation'

    12 months after baseline questionnaire

  • Change in patient reported depression symptoms

    From baseline to measurements at 2, 6 and 12 months

  • Change in patient reported anxiety symptoms

    From baseline to measurements at 2, 6 and 12 months

  • Change in patient reported general health status

    From baseline to measurements at 2, 6 and 12 months

  • +1 more secondary outcomes

Study Arms (3)

Training with pro-active identification

EXPERIMENTAL

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

Other: TrainingOther: Pro-active identification

Training without pro-active identification

EXPERIMENTAL

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

Other: Training

Control

NO INTERVENTION

Care as usual according to national applicable primary guide guidelines.

Interventions

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

Training with pro-active identificationTraining without pro-active identification

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.

Model Details: 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.
