BACKGROUND: Immunoglobulin 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.
METHODS: This 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.
RESULTS: In 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.
CONCLUSIONS: Secondary 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.

The mission of Food and Drug Administration (FDA)\'s Center for Devices and Radiological Health is to protect and promote public health. It assures that patients and providers have timely and continued access to safe, effective, and high-quality medical devices and safe radiation-emitting products by providing meaningful and timely information about the products we regulate and the decisions we make. On September 17, 2021, an FDA workshop was held to provide information to stakeholders, including members of the spine community, device manufacturers, regulatory affairs professionals, clinicians, patients, and the general public regarding FDA regulations, guidance and regulatory pathways related to spinal device clinical review. It was not intended to communicate any new policies, processes, or interpretations regarding medical device marketing authorizations. This workshop consisted of individual presentations, group discussions, question and answer sessions, and audience surveys. Information-sharing included discussions related to patient-reported outcomes, clinician-reported outcomes, observer-reported outcomes, and performance outcomes. Discussions involving external subject matter experts covered topics related to spinal device clinical studies including definition of a target population, enrollment criteria, strategies for inclusion of under-represented patient groups, reporting of adverse event and secondary surgical procedures, clinical study endpoints, and clinical outcome assessments. A meeting transcript and webcast workshop link are currently posted on the FDA website. Important related issues and challenges were discussed, and an exciting range of new ideas and concepts were shared which hold promise to advance regulatory science, patient care and future innovation related to spinal devices.

As part of efforts to improve study design, the use of outcome measures in randomized controlled trials (RCTs) in traumatic brain injury (TBI) is receiving increasing attention. This review aimed to assess how clinical outcome assessments (COAs) have been used and reported in RCTs in adult TBI. Systematic literature searches were conducted to identify medium to large (n ≥ 100) acute and post-acute TBI trials published since 2000. Data were extracted independently by two reviewers using a set of structured templates. Items from the Consolidated Standards of Reporting Trials (CONSORT) 2010 Statement and CONSORT patient-reported outcomes (PROs) extension were used to evaluate reporting quality of COAs. Glasgow Outcome Scale/Extended (GOS/GOSE) data were extracted using a checklist developed specifically for the review. A total of 126 separate COAs were identified in 58 studies. The findings demonstrate heterogeneity in the use of TBI outcomes, limiting comparisons and meta-analyses of RCT findings. The GOS/GOSE was included in 39 studies, but implemented in a variety of ways, which may not be equivalent. Multi-dimensional outcomes were used in 30 studies, and these were relatively more common in rehabilitation settings. The use of PROs was limited, especially in acute study settings. Quality of reporting was variable, and key information concerning COAs was often omitted, making it difficult to know how precisely outcomes were assessed. Consistency across studies would be increased and future meta-analyses facilitated by (a) using common data elements (CDEs) recommendations for TBI outcomes and (b) following CONSORT guidelines when publishing RCTs.
