Acerca de la investigación
People with advanced liver disease often experience complex physical symptoms, emotional concerns, and practical difficulties, especially as their illness progresses. Currently, there are no questionnaires designed specifically to capture these needs and experiences. A purposely designed questionnaire could help healthcare professionals better understand patients' needs and improve the care they receive. The questionnaire must be tested to make sure that it is reliable, accurate and acceptable to patients. This process is known as validation.
This study is testing a new questionnaire called the Integrated Palliative care Outcome Scale- Liver (IPOS-Liver). It asks about symptoms and concerns experienced by people living with advanced liver disease.
The study will take place in two NHS hospitals in England. 71 NHS patients with advanced chronic liver disease will take part, together with healthcare professionals involved in their care. Patients and healthcare professionals will be asked to complete the IPOS-Liver questionnaire alongside other established questionnaires. These will be completed at two time points a few days apart. The results will be statistically analysed to see whether the new questionnaire gives consistent and useful results. A small number of patients will additionally be invited to take part in a 30-minute interview about their experience of completing the IPOS-Liver. Adult NHS patients in England will be invited to take part after the clinician caring for them identifies that they are eligible for the study.

This multi location, longitudinal, observational mixed methods study will evaluate the psychometric properties of the Integrated Palliative Care Outcome Scale-Liver (IPOS Liver). The IPOS Liver is a newly developed patient reported outcome measure within the IPOS family, designed to capture symptoms, concerns, and unmet palliative care needs specific to people with advanced chronic liver disease (ACLD). Existing outcome measures do not fully reflect the unique palliative symptoms experienced by this population.
The IPOS Liver was developed in collaboration with a patient and public involvement and engagement (PPIE) group and an expert panel comprising hepatology and palliative care clinicians. This study will assess the measure's psychometric properties in 71 adults with ACLD receiving care in hospitals, hospices, or outpatient settings across England using a consecutive eligibility sampling strategy.
Validity and reliability will be examined through correlations between IPOS Liver scores and established clinical outcome measures, assessment of change in IPOS Liver scores over two time points, and evaluation of whether IPOS-Liver score changes correspond with clinical change. In addition, the views and experiences of using the IPOS Liver will be explored through qualitative interviews with a purposively sampled subgroup of patients and healthcare professionals to further support content validity.
The study will be conducted in two locations in England and will be supported by clinicians affiliated with the British Association for the Study of the Liver (BASL) Palliative Hepatology Specialist Interest Group. Ethical safeguards including on-going capacity assessments to ensure decision-specific consent and the right to withdraw with full data deletion, will protect vulnerable participants. Findings from this 18 month study will determine whether the IPOS Liver is a reliable and valid outcome measure suitable for use in clinical practice and research involving people with ACLD

- Is expected to be reviewed on two occasions within 5 days as an inpatient, or is being cared for as an outpatient.
Exclusion Criteria:
- Patients without capacity to consent as judged by the clinical team
- Patients currently too symptomatic or distressed to participate, as judged by the clinical team
- Patients unable to understand written and verbal communication in English
Staff members caring for patients will also become participants in the study.
Staff-participant inclusion criteria are:
- Be a healthcare professional involved with the care of a participant enrolled in the study

Qué evalúan los investigadores
Estas medidas indican qué se estudia. No prueban que un tratamiento funcione.
Medidas principales
Construct Validity
Plazo: Up to 21 days
Construct validity establishes the theoretical relationship between variables on the new IPOS-Liver and those on established measures of the same construct and scores between sub-groups of participants (DeVellis \& Thorpe, 2022). This will be established by exploring convergent and divergent validity as well as known group comparisons.
Medidas secundarias
Internal consistency
Plazo: Up to 21 days
Internal consistency reflects how closely items on the IPOS-Liver are related, or measure the same underlying construct.
Inter-rater reliability
Plazo: Up to 21 days
Inter-rater reliability is the degree of agreement between different raters using the IPOS-Liver.
Content and face validity
Plazo: Up to 21 days
The extent to which items reflect the construct being measured.
Floor and ceiling effects
Plazo: Up to 21 days
The percentage of participants (staff or patients) who have either maximum or minimum IPOS-Liver scores will be calculated.
