Brief Summary

The web application gp-multitool.de is a digital tool for implementing the German S3 clinical practice guideline for multimorbidity of the German Society of General Practitioners and Family Physicians in primary care. The tool enhances evidence-based and patient-centered care by assessing and providing information relevant for the primary care of this patient group. This cluster-randomised clinical evaluation study examines the effectiveness of an intervention based on gp-multitool.de in general practitioner (GP) practices in Germany.

Outcome Measures

Primary Outcomes (1)

  • Whether patients have stayed at least once for at least one night in hospital during the preceding twelve months

    The outcome will be assessed by a standardised questionnaire. The patients will be asked how often they had been in hospital during the preceding twelve months and how long these stays had lasted. Before analysis, the outcome will be dichotomised.

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

Secondary Outcomes (7)

  • The number of contacts with the GP during the preceding twelve months

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

  • The number of contacts with outpatient specialists during the preceding twelve months

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

  • Quality of care as assessed by the summary score of the "GP-reported core set of quality indicators for older adults with multimorbidity in primary care" during the preceding twelve months

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

  • Quality of care as assessed by the summary score of the "patient-reported core set of quality indicators for older adults with multimorbidity in primary care" during the preceding twelve months

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

  • Self-rated health as assessed by the EuroQoL visual analogue scale

    Once at baseline (before randomization of practices) and once at follow-up (immediately after the intervention)

  • +2 more secondary outcomes

Study Arms (2)

NO INTERVENTION

Care as usual

Intervention group

EXPERIMENTAL

GPs in the intervention arm have to use the web application gp-multitool.de. For every participating patient they have to use at least four specific questionnaires in the first six intervention months, i.e. 1a is required, and either 2a or 2b, and either 3a or 3b, and either 4a or 4b or 4c. In the following six intervention months, GPs in the intervention arm also have to use at least four specific questionnaires, i.e., 1a is required again, and either 2a or 2b, and either 3a or 3b, and either 4a or 4b or 4c. Results from the questionnaires need to be discussed between GPs and patients. Additionally, at least one medication review during the first six intervention months is obligatory.

Other: gp-multitool.de

Interventions

The intervention is based on the digital tool gp-multitool.de. The GPs can send questionnaires by email to patients and patients can fill out questionnaires at their home or in the waiting room of the practice using any digital device with browser and access to the internet. The digital tool also includes instructions for conducting a medication review. Results will be available from the computers of attending GPs. Decisions from talks between GPs and patients can be documented in the tool. The tool includes ten questionnaires: 1. patient preferences (including a. treatment goals, and b. involvement of other persons in decision making); 2. social life (including a. activities and participation, and b. social support); 3. treatment situation (including a. problems with medication, and b. treatment burden); 4. health complaints (including a. pain, b. psychiatric disorders, and c. other complaints). 5. resilience and protective behavior against heat.
