Primary Palliative Care - a Feasibility Cluster Trial (PrimPal)

July 31, 2026 updated by: Carlos Seiça Cardoso, University of Coimbra
This feasibility cluster-controlled randomized trial (RCT) evaluates a complex intervention for the delivery of primary palliative care in Family Health Units (FHUs). The intervention consists of training General Practitioners (GPs) in palliative care through a 30 hour e-learning program and implementing a structured consultation model (4 consultations over 12 weeks) for adult patients with advanced chronic illness. One FHU will receive the intervention and one FHU will follow usual care. The primary goal is to assess feasibility metrics (GP adherence, patient recruitment rate, and patient retention rate), which will inform the design of a subsequent full-scale cluster RCT.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Detailed Description

Background: Demographic ageing and the rising burden of chronic disease have dramatically increased the need for palliative care. Most patients with palliative care needs are cared for in primary health care (PHC) settings, yet GPs often lack training and systematic tools to identify and manage these patients. The Principal Investigator developed a complex intervention combining GP training and a new consultation model during doctoral research, demonstrating promising results (reduction in physical and psychological symptoms) in a before-after study (published in Palliative Medicine, DOI: 10.1177/02692163231219682). The present feasibility trial is the next methodological step before undertaking a full-scale cluster RCT.

Design: Feasibility cluster-controlled RCT with an embedded qualitative component (mixed-methods). Randomisation occurs at the cluster (FHU) level. Two FHUs from ULS Coimbra (central Portugal) will be recruited: one allocated to the intervention arm and one to the control (usual care) arm.

Intervention: GPs in the intervention FHU will complete a 30hour e-learning training programme covering palliative care communication, symptom management, and patient assessment/control. After training, each GP will apply the new structured consultation model to recruited patients over 12 weeks (4 consultations). The model is grounded in the 4th edition of the National Consensus Project's Clinical Practice Guidelines for Quality Palliative Care and WONCA's core competencies for GPs in palliative care.

Control: GPs in the control FHU will follow usual care without any specific palliative care training or structured consultation model.

Participants: Adult patients (≥18 years) on the list of recruited GPs with a diagnosis of: advanced-stage neoplasm (metastatic cancer), COPD GOLD III/IV, Congestive Heart Failure NYHA III/IV, or Chronic Kidney Disease stage IV/V.

Feasibility outcomes: GP implementation rate (primary), patient recruitment rate, and patient retention rate will be assessed at baseline (T0), week 6 (T1), and week 12 (T2). Qualitative data will be collected through interviews with GPs and patients to explore perceived barriers and benefits of the intervention.

Significance: Results will be used to refine the intervention and study procedures, and to power a future definitive cluster RCT.

Enrollment (Estimated)

Enrollment

30

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  • Advanced-stage neoplasm (metastatic/stage IV cancer);
  • Chronic Obstructive Pulmonary Disease (COPD) - GOLD classification III or IV;
  • Congestive Heart Failure (CHF) - New York Heart Association (NYHA) functional classification III or IV;

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control (Usual Care)
GPs in the control FHU deliver usual palliative care without specific training or structured consultation model.
Experimental: Primary Palliative Care Consultation
General Practitioners in the intervention FHU complete a 30hour e-learning training programme in palliative care and apply a new structured consultation model over 12 weeks (4 consultations) with recruited patients.
Other: Primary Palliative Care Complex Intervention (PrimPal)
  1. GPs will receive an e-learning palliative care training programme with a 30-h load, including topics such as the role of communication, the main problems and symptoms of patients with palliative care needs and how to assess and control them. Additionally, the programme covered how to apply the newly developed medical consultation model and how to use the Integrated Palliative Care Outcome Scale (IPOS) patient version
  2. Primary palliative care consultation model divided into five areas (1) summarizing clinical information, (2) objective symptoms' management, (3) assessment and coding of chronic diseases and symptoms, (4) planning clinical approach and (5) addressing other problems/concerns - 4 consultations over 12 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
GP Feasibility Rate (Implementation Rate)
Time Frame: 12 weeks (from start of intervention to end of consultation cycle - Week 12 / T2)
Percentage of GPs in the intervention arm who successfully implement the new consultation model with their recruited patients (excluding failures due to reasons unrelated to the physician, e.g., patient death or withdrawal). Feasibility is considered demonstrated if ≥70% of GPs complete the model with at least 80% of their recruited patients.
