Development of a Conceptual Model of Chronic Lymphocytic Leukemia to Better Understand the Patient Experience.

ABSTRACT:

Background and objective

Understanding the patient experience is important for identifying the unmet need in chronic lymphocytic leukemia. The current study aimed to develop a comprehensive chronic lymphocytic leukemia conceptual model.

Methods

The conceptual model was based on literature searches, review of chronic lymphocytic leukemia patient blogs/forums, and interviews with five expert clinicians, with 20 patients who received at most one treatment (first line) for their chronic lymphocytic leukemia, and with 20 patients with relapsed or refractory chronic lymphocytic leukemia. De-identified interviews were transcribed, coded, and evaluated using qualitative data analysis software.

Results

Thirty-five prevalent chronic lymphocytic leukemia-related symptom and impact concepts were identified from literature searches, patient blogs/forums, and clinician interviews. Patient interviews confirmed the identified concepts and revealed five additional concepts. Fatigue-related sub-components were identified from how patients described their fatigue, covering symptoms (tiredness/need for sleep, lack of energy, weakness, cognitive fatigue), and impacts (decreased ability to maintain their social, familial, or professional role, decreased physical functioning, frustration). Three versions of the conceptual model were created: an overall model with all concepts; a model highlighting the most prominent concepts in first line; and a model highlighting the most prominent concepts in relapsed or refractory disease. Prominent concepts in both first line and relapsed or refractory disease were fatigue-related symptoms and impacts, muscle/joint aches, night sweats, bruising, fever, recurrent infections/illness, insomnia, decreased cognitive/emotional functioning, anxiety/worry, stress, depression, financial difficulty, and fear of death. Dyspnea and cough were prominent in first line only, and enlarged lymph nodes, headaches, pain/discomfort, weight loss, nausea/vomiting, and infusion reactions were prominent in relapsed or refractory disease only.

Conclusions

The results show that fatigue is a dominant issue affecting patients with chronic lymphocytic leukemia. The three versions of the conceptual model can help researchers to understand patients' unmet needs and guide the patient-reported outcome strategy for clinical trials.

Project description:BackgroundPatient-reported outcome (PRO) instruments should capture the experiences of disease and treatment that patients consider most important in order to inform patient-centred care and product development. The aim of this study was to develop a preliminary conceptual model of patient experience in chronic kidney disease (CKD) based on a targeted literature review and to characterize existing PRO instruments used in CKD.MethodsPubMed, EMBASE and Cochrane databases and recent society meetings were searched for publications reporting signs/symptoms and life impacts of CKD. Concepts identified in the literature review were used to develop a preliminary conceptual model of patient experience of CKD, overall, and within patient subpopulations of differing CKD causes, severities and complications. PRO instruments, identified from PRO databases, CKD literature and CKD clinical trials, were assessed for content validity, psychometric strength and coverage of concepts in the literature review.ResultsIn total, 100 publications met criteria for analysis; 56 signs/symptoms and 37 life impacts of CKD were identified from these sources. The most frequently mentioned signs/symptoms were pain/discomfort (57% of publications) and tiredness/low energy/lethargy/fatigue (42%); the most commonly reported life impacts were anxiety/depression (49%) and decrements in physical functioning (43%). Signs/symptoms and life impacts varied across the subpopulations and were more frequent at advanced CKD stages. The preliminary conceptual model grouped signs/symptoms into seven domains (pain/discomfort; energy/fatigue; sleep-related; gastrointestinal-related; urinary-related; skin-/hair-/nails-related; and other) and life impacts into six domains (psychological/emotional strain; cognitive impairment; dietary habit disruption; physical function decrements; interference with social relationships; and other). Eleven PRO instruments were considered to be promising for use in CKD; all had limitations.ConclusionsAlthough preliminary, the proposed conceptual model highlights key PROs for people with CKD and is intended to spur development of more tailored PRO instruments to assess these concepts.

Project description:IntroductionImmunoglobulin A nephropathy (IgAN) is a kidney disorder that can lead to progressive kidney disease. Currently, there lacks a comprehensive overview of the symptoms and impacts experienced by those living with IgAN that would help inform the selection or development of fit-for-purpose clinical outcome assessments (COA) to be used in clinical trials. The aim of this study was to develop a conceptual model of the adult and pediatric patient experience of IgAN, including disease signs and symptoms, treatment side effects, and impact on functioning and well-being.MethodsThis study comprised a systematic review and thematic analysis of qualitative studies with adults and children diagnosed with IgAN. Data sources were identified through an electronic database search of journal articles (MEDLINE, Embase, PsycINFO; June 2021), hand-searching of conference proceedings, patient advocacy group websites, and gray literature. Non-English articles were excluded. Identified data (patient/caregiver quotes, author summaries, and interpretations of patient experiences) were extracted from articles. Extracted data were qualitatively analyzed, aided by ATLAS.ti v7. Codes were applied to data; concepts (i.e., symptoms) were identified, named, and refined. A conceptual model was developed by grouping related concepts into domains.ResultsIn total, five sources were identified for analysis: two journal articles, two online anthologies of patient stories, and one patient organization-sponsored "Voice of the Patient" meeting report. Conceptual model symptom domains included swelling/puffiness (edema), pain/aches/discomfort, fatigue, weight gain, sleep problems, urinary problems, and gastrointestinal problems. Impact domains included emotional/psychological well-being, physical functioning/activities of daily living, social functioning, work/school, and relationships.ConclusionsSecondary analysis of published qualitative literature permitted development of a novel conceptual model depicting the patient experience of IgAN; however, its depth is limited by a lack of available literature. Further qualitative research is recommended to refine and/or confirm the concepts and domains, determine any relationships between them, and explore the outcomes that are most meaningful to patients. The refined model will provide a useful tool to inform the selection, development, and/or amendment of COAs for use in future IgAN clinical trials.
