NCT05842928

Brief Summary

The PARTNER study is a multicentre, two-arm, pragmatic cluster-randomised trial evaluating the impact of a focused and patient-centred cooperation between general practitioners (GPs) and community pharmacists (PARTNER intervention) on reductions in the use of psychotropic, sedative and anticholinergic potentially inappropriate medication (PSA-PIM) compared to a control intervention. The PARTNER intervention comprises (1) education for health care professionals, (2) an interprofessional workshop and case conference, (3) a pharmacy visit with brown bag/medication review and patient empowerment, (4) GP practice visit with shared decision making. The control intervention only comprises a pharmacy visit with brown bag review.

Outcome Measures

Primary Outcomes (1)

  • Reduction in the PSA-PIM Drug Burden Index (DBI) by ≥ 0.15 points

    Clinically relevant reduction in PSA-PIM exposure at patient level after 6 months follow-up, as measured by the Drug Burden Index method. The primary endpoint is defined as a responder endpoint at patient level, where response is defined as a reduction in the Drug Burden Index (DBI) by ≥ 0.15 points (Primary endpoint: T2 vs T0)

    6 months

Secondary Outcomes (11)

  • Reduction in the PSA-PIM Drug Burden Index (DBI) by ≥ 0.15 points

    12 months

  • Frequency of deprescribing PSA-PIM stratified by PSA-PIM subgroups

    12 months

  • Total exposure with PSA-PIM

    12 months

  • Total exposure to PSA-PIM stratified by PSA-PIM subgroups

    12 months

  • Frequency of new PSA-PIM prescriptions

    12 months

  • +6 more secondary outcomes

Study Arms (2)

Intervention Arm

EXPERIMENTAL

Intensified and patient-centred cooperation between GPs and pharmacists including patient empowerment

Behavioral: PARTNER intervention

Control Arm

ACTIVE COMPARATOR

Extended routine care

Behavioral: Control intervention

Interventions

The PARTNER intervention includes the following components: 1. Education for health care professionals A) written manual on deprescribing PSA-PIM, which consists of brief information and more detailed explanations; B) access to digital instructional videos/podcasts that address potential problems in deprescribing and provide possible solutions; C) checklist for identification of drug-related problems for pharmacists; D) tapering support tool to facilitate the selection of tapering schemes; E) divisibility list for PSA-PIM to support the implementation of tapering schemes; F) empowerment brochures for patients each focussing on one PSA-PIM subgroup 2. Interprofessional workshop and case conference for GPs and pharmacists 3. Pharmacy visit (brown bag/medication review) including patient empowerment 4. GP practice visit including shared decision making (SDM)

Intervention Arm

The control intervention only comprises a pharmacy visit with brown bag review.

Healthy VolunteersNo
Age GroupsOlder Adult (65+)

You may qualify if:

  • Aged 65 years or older
  • Patient is capable of giving consent

Masking Details
To avoid selection bias and Hawthorne bias, the collaborating units (GP practice and community pharmacy) in the intervention group are blinded to the target drugs (PSA-PIM) until the time of randomisation, and in the control group until the end of the study. The same applies to patient participants.
