      <textblock>
        The goal of this cluster based intervention trial is to evaluate the effect of a nurse-led&#xD;
        patient education program on dry mouth in patients with a life-limiting condition or frailty.&#xD;
  &#xD;
        The Mouth Educational Program (MEP) is a nurse-led patient education program, in which&#xD;
        trained nurses use current clinical, palliative dry mouth guidelines in a structured manner&#xD;
        to discuss causes, consequences and interventions with the patients and to create an&#xD;
        appropriate treatment plan. This intervention will be compared to a control group receiving&#xD;
        care as usual.&#xD;
  &#xD;
        Therefore, the main question it aims to answer is:&#xD;
  &#xD;
        Does a nurse-led patient education program reduce dry mouth complaints in patients with a&#xD;
        life-limiting condition or frailty?&#xD;
  &#xD;
        Participants will be asked to answer questionnaires and, when part of the intervention group,&#xD;
        partake in the Mouth Educational Program (MEP).&#xD;

  The goal of this cluster based intervention trial is to evaluate the effect of a nurse-led
        patient education program on dry mouth in patients with a life-limiting condition or frailty.
  
        The Mouth Educational Program (MEP) is a nurse-led patient education program, in which
        trained nurses use current clinical, palliative dry mouth guidelines in a structured manner
        to discuss causes, consequences and interventions with the patients and to create an
        appropriate treatment plan. This intervention will be compared to a control group receiving
        care as usual.
  
        Therefore, the main question it aims to answer is:
  
        Does a nurse-led patient education program reduce dry mouth complaints in patients with a
        life-limiting condition or frailty?
  
        Participants will be asked to answer questionnaires and, when part of the intervention group,
        partake in the Mouth Educational Program (MEP).

  description: Barriers and facilitators of the current guidelines are examined in focus groups with nurses from either arm.
  measure: Cost-effectiveness Analysis (CEA) of the MEP, as compared to the control group
  time frame: Week 0, 4, 8 and 12.
  description: The CEA is based upon patient-reported medical costs as measured by the Institute for Medical Technology Assessment (iMTA) Medical Consumption Questionnaire (iMCQ). It encompasses use of medical and paramedical treatments or services, in- and outpatient care and use of medication. Here, the questionnaire consists of three main questions asking for the frequency of contact with dental services, the frequency of contact with health care professionals across different disciplines and the purchase of dry mouth treatment products (e.g. medication and other aids) in the last four weeks.
  arm group label: Intervention
  arm group type: Experimental
  description: In the intervention group, the nurse and participant will be using the Mouth Education Program (MEP) to discuss causes, consequences and interventions for dry mouth in a structured manner, ultimately leading to an appropriate, individual treatment plan.
  The MEP is based on current clinical, national palliative care guidelines on dry mouth care.
  arm group label: Control
  arm group type: Active Comparator
  description: The control group will receive care as usual, provided by their trusted, treating clinicians and care teams. Questionnaires will be administered by researchers.
