Updated Public Health Impact and Cost Effectiveness of Recombinant Zoster Vaccine in Canadian Adults Aged 50 Years and Older.

OBJECTIVES: The aim of this study was to update previously estimated public health impact and cost effectiveness of recombinant zoster vaccine (RZV) for the prevention of herpes zoster (HZ) in Canadians aged ≥50 years using longer-term RZV efficacy and waning data and real-world coverage and completion. METHODS: A multicohort Markov model was used to conduct a cost-utility analysis comparing RZV with no HZ vaccination among Canadians aged ≥50 years. Real-world data were used for first-dose coverage (17.5%) and second-dose completion (65%). Vaccine efficacy and waning data were applied from up to 8-year follow-up from the ZOE-50 and ZOE-70 clinical trials. Incremental costs and benefits were calculated using a lifetime horizon from the healthcare payer (base case) and societal perspectives. A discount rate of 1.5% was applied to costs and quality-adjusted life-years (QALYs). RESULTS: The model estimated that RZV would prevent 303,835 HZ cases, 83,256 post-herpetic neuralgia (PHN) cases, 39,653 other complications, and 99 HZ-related deaths compared with no HZ vaccination. Incremental cost-effectiveness ratios (ICERs) were estimated to be $27,486 and $22,097 per QALY (2022 Canadian dollars [CAN$]) from the healthcare payer and societal perspectives, respectively. The base-case ICER was most sensitive to a lower percentage of initial HZ cases with PHN. Almost all probabilistic sensitivity analysis simulations (98.1%) resulted in ICERs

Attitudes, barriers, and facilitators to adherent completion of the recombinant zoster vaccine regimen in Canada: Qualitative interviews with healthcare providers and patients.

This qualitative, cross-sectional study aimed to understand the barriers and facilitators related to the adherence and completion of the recombinant zoster vaccine (RZV) two-dose series in Canada, as perceived by healthcare providers (HCPs) and patients. Data collection occurred via 60-minute concept elicitation interviews with 12 HCPs (4 physicians, 2 nurse practitioners, 6 pharmacists) who had prescribed and/or administered RZV in Canada, and 21 patients aged ≥50 years who had received ≥1 dose of RZV. Patients were categorized as adherent (received both doses within the recommended 2-to-6-month timeframe; n = 11) or non-adherent (received only one dose or second dose outside the recommended timeframe; n = 10). Interview transcripts were coded and analyzed using a two-part thematic analysis approach. HCP-identified barriers to RZV adherence included high out-of-pocket cost, inconsistent/lack of health plan coverage, inconvenient processes for accessing RZV, and patient forgetfulness. HCP-identified facilitators included desire for shingles protection, HCP encouragement, and reminders. Barriers to RZV adherence identified by patients included lack of HCP knowledge/experience with RZV, receiving unreliable/confusing information, having unpleasant/severe side effects following the first dose, high out-of-pocket cost, lack of insurance coverage, and forgetfulness. Patient-identified facilitators included self-motivation, financial support, convenient processes for obtaining RZV, and reminders. In conclusion, many factors can influence RZV series completion and adherence among adults in Canada, including cost, insurance coverage, HCP knowledge and encouragement, and reminders. Awareness of these factors may inform HCPs in helping patients overcome barriers and identify opportunities for future consideration, facilitating protection against herpes zoster.

Canadian patient experiences of lupus nephritis: a qualitative analysis.

OBJECTIVE: Lupus nephritis (LN) is one of the most severe manifestations of SLE; however, we know little about the lived experience of LN. This research investigates patient experiences and perspectives of (1) LN diagnosis; (2) living with LN; and (3) LN healthcare and treatment. METHODS: Patients aged ≥18 years with biopsy-proven pure or mixed International Society of Nephrology/Renal Pathology Society class III, IV or V LN were purposefully recruited from a Canadian lupus cohort to participate in semistructured in-depth interviews. RESULTS: Thirty patients with LN completed the interviews. The mean (SD) age was 42.1 (16.4) years, and 86.7% were female. Participants described challenges seeking, receiving and adjusting to a LN diagnosis, and some reported that their diagnosis process took weeks to years. While 16 participants were provided resources by healthcare providers to help them through the process of diagnosis, the need for accessible LN-specific information at diagnosis was highlighted (n=18). Participants also described the unpredictability of living with LN, particularly related to impacts on physical and mental health, relationships, leisure activities, employment and education, and family planning. While most (n=26) participants reported a positive impression of their care, the side effects of LN medications and the need to increase patient and societal awareness/understanding of LN were highlighted in the context of healthcare and treatment. CONCLUSIONS: The unpredictability of living with LN, the heavy treatment burden and a lack of patient/societal awareness substantially affect the lived experience of LN. These findings will inform the development of LN-specific patient resources to increase understanding of LN and improve well-being for patients.
