Patient Relat Outcome Meas 2023; 14:297-304. [PMID: 37840834 PMCID: PMC10576564 DOI: 10.2147/prom.s421211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 09/13/2023] [Indexed: 10/17/2023] Open
Abstract
Purpose The purpose of this secondary data analysis was to examine the association between hematologic response and health-related quality of life (HRQoL) among patients with light-chain (AL) amyloidosis. Patients and Methods Data for this secondary analysis were collected through a non-interventional, longitudinal, online self-report survey of patients with AL amyloidosis. Patients completed an initial online survey, with follow-up surveys administered 1, 6, 12, 18, and 24 months after completion of the initial survey. The online survey included an assessment of patients' most recent self-reported hematologic response status. Eight domains and 2 summary components of HRQoL were evaluated with the SF-36v2® Health Survey. A series of logistic regression models were used to examine the association between self-reported hematologic response at 24 months (dichotomized as new or maintained complete hematologic response; less than a complete response) and change in HRQoL from baseline to 24 months (dichotomized as meaningful worsening; improvement or preservation). Results For all measured domains of HRQoL except physical functioning, there was no statistically significant relationship between meaningful worsening in HRQoL and hematologic response status at 24 months. Patients without a complete hematologic response had an odds of experiencing meaningful worsening of HRQoL that was similar to that of patients with a complete hematologic response. Conclusion Among patients with AL amyloidosis, change in HRQoL was generally not associated with hematologic response. Achieving a complete hematologic response does not necessarily mean that a patient will experience increased or stable HRQoL. When defining treatment success, it is important to recognize that clinical markers such as hematologic response may not fully encapsulate the patient experience.

Using a Modified Delphi Panel to Estimate Health Service Utilization for Patients with Advanced and Non-Advanced Systemic Light Chain Amyloidosis. CLINICOECONOMICS AND OUTCOMES RESEARCH 2023; 15:673-680. [PMID: 37719133 PMCID: PMC10503521 DOI: 10.2147/ceor.s412079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 08/25/2023] [Indexed: 09/19/2023] Open
Abstract
Purpose Patients with diagnosed with systemic light chain (AL) amyloidosis at advanced Mayo stages have greater morbidity and mortality than those diagnosed at non-advanced stages. Estimating service use by severity is difficult because Mayo stage is not available in many secondary databases. We used an expert panel to estimate healthcare utilization among advanced and non-advanced AL amyloidosis patients. Patients and Methods Using the RAND/UCLA modified Delphi method, expert panelists completed 180 healthcare utilization estimates, consisting of inpatient and outpatient visits, testing, chemotherapy, and procedures by disease severity and organ involvement during two treatment phases (the 1 year after starting first line [1L] therapy and 1 year following treatment [post-1L]). Estimates were also provided for post-1L by hematologic treatment response (complete or very good partial response [CR/VGPR], partial, no response or relapse [PR/NR/R]). Areas of disagreement were discussed during a meeting, after which ratings were completed a second time. Results During 1L therapy, 55% of advanced patients had ≥1 hospitalization and 38% had ≥2 admissions. Rates of hematopoietic stem cell transplant (HSCT) in advanced patients were 5%, while pacemaker or implantable cardioverter defibrillator (ICD) placement were 15%. During post-1L therapy, rates of hospitalization in advanced patients remained high (≥1 hospitalization: 20-43%, ≥2 hospitalizations: 10-20%), and up to 10% of advanced patients had a HSCT. Ten percent of these patients underwent pacemaker/ICD placement. Conclusion Experts estimated advanced patients, who would not be good candidates for HSCT, would have high rates of hospitalization (traditionally the most expensive type of healthcare utilization) and other health service use. The development of new treatment options that can facilitate organ recovery and improve function may lead to decreased utilization.

Abstract
Introduction: Treatment of amyloid light-chain (AL) amyloidosis, a rare disease with a <5-year lifespan, remains challenging. This systematic literature review (SLR) aimed to evaluate the current evidence base in AL amyloidosis. Methods: Literature searches on clinical, health-related quality of life, economic and resource use evidence were conducted using the Embase, MEDLINE and Cochrane databases as well as gray literature. Results: This SLR yielded 84 unique studies from: five randomized controlled trials; 54 observational studies; 12 health-related quality of life studies, none with utility values; no economic evaluation studies; and 16 resource use studies, none with indirect costs. Conclusion: This SLR highlights a paucity of published literature relating to randomized controlled trials, utility values, economic evaluations and indirect costs in AL amyloidosis.
