PRO Development for ANCA Associated Vasculitis
A qualitative study using interviews with patients who have antineutrophil cytoplasm antibody (ANCA) associated vasculitis, to develop a patient reported outcome (PRO)measure
|Study Design:||Time Perspective: Prospective|
|Official Title:||A Qualitative Study Using Interviews With Patients Who Have Anti-neutrophil Cytoplasm Antibody (ANCA) Associated Vasculitis, to Develop a Patient Reported Outcome (PRO) Measure|
- This is a qualitative research study based on semi-quantitive exploratory patient interviews and therefore it is not appropriate to define only one outcome measure. [ Time Frame: No formal outcome measure therefore not applicable ] [ Designated as safety issue: No ]
The principle research objective: The investigators are going to interview patients with anti-neutrophil cytoplasm antibody associated vasculitis, to develop and pilot questionnaire items for a patient reported outcome measure specifically for their disease.
The secondary research objective is to describe the impact of ANCA-associated vasculitis on the quality of life of patients attending the Oxford University Hospitals NHS Trust, based on individual anonymised interviews.
|Study Start Date:||September 2012|
|Estimated Study Completion Date:||August 2014|
|Estimated Primary Completion Date:||February 2014 (Final data collection date for primary outcome measure)|
Patients with antineutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) have inflammation in the small blood vessels leading to involvement in different body areas, e.g., the kidneys, lungs and skin. Untreated, the risk of death is over 80%; with current treatment, patients often suffer from ongoing disease activity, damage or treatment side effects which have a negative impact on quality of life. Because patients with AAV can have a wide range of disease features, the investigators hypothesise that general patient reported outcome (PROs) measurements, may not be specific enough to describe the full impact on quality of life.
The main objective of this project is to start from patients' experiences to develop a disease specific PRO for patients with AAV. Patients diagnosed with AAV will be recruited through clinics or inpatients at the Oxford University Hospitals (OUH) National Health Service (NHS) Trust, or, if the patients have previously consented to be contacted about future studies, through the Diagnostic and Classification of Vasculitis (DCVAS) or The Characterisation and Determinants of Quality of Life in ANCA Associated Vasculitis (VasQoL) study databases. After informed consent is obtained, individual patient interviews will be conducted; these will last for approximately one hour and will be recorded and transcribed. Themes will be independently extracted and amalgamated by the researchers. Approximately 25 patients with different types of ANCAassociated vasculitis and varying disease duration will be interviewed until saturation, i.e., no new substantive themes emerge. These themes will then evolve into individual candidate questionnaire items. Candidate items will be piloted on approximately 25 different patients with AAV using questionnaires and interviews, until no further comments arise, to produce a final set of candidate questionnaire items. The duration of the study 1.5 years.
