In general, governments and health authorities have taken precautions during the COVID-19 pandemic to reduce the viral spread and protect vulnerable citizens. Patients with multiple myeloma (MM) have an increased risk of being infected with COVID-19 and developing a fatal course due to the related immunodeficiency. We investigated how Danish patients with MM reported their quality of life (QoL) pre-COVID and during COVID, in an ongoing longitudinal QoL survey. The responses given during the first and second wave of the COVID-19 pandemic were pooled, analyzed and compared to the same period the year before. We hypothesized that locking down the society would have caused deteriorated QoL and that patients living alone and those under the age of 65 would be particularly affected by the situation. Surprisingly, our study showed the opposite. Statistically significant and clinically relevant differences were primarily found during the first lock down and represented reduced fatigue, improved role functioning, decreased insomnia and improved physical health summaries in patients below 65 years of age. These results indicate that Danish patients with MM might have felt protected and safe by COVID restrictions. Otherwise, the questionaries used in QoL-MM survey may not have been able to capture the impact of the COVID-19 pandemic. Importantly, this indicates that QoL survey data obtained in clinical studies, in countries with highly developed health-care systems using standard questionnaires during the pandemic, allow room for interpretation without being adjusted for the impacts of the pandemic.

Background: The severe, acute respiratory syndrome, coronavirus 2 (SARS-CoV-2), leading to coronavirus-19 (COVID-19), was detected for the first time in Wuhan, China in December 2019. In general, governments and health authorities have taken precautions during the COVID-19 pandemic to reduce viral spread and protect vulnerable citizens. Patients with multiple myeloma (MM) have an increased risk of being infected with COVID-19 and developing a fatal course due to the MM-related immunodeficiency (Glenthøj, A et al. PMID: 32939853). To some extent, the COVID-19 pandemic has changed standard of care towards extended use of oral regimens and limiting hospital visits (Terpos E et al.PMID: 32444866). We aimed to investigate the quality of life (QoL) of Danish patients with MM during the COVID-19 pandemic. We hypothesized that patients living alone and those under the age of 65 years, as a consequence of the pandemic, would experience impaired QoL due to social isolation and fear of infection with SARS-CoV-2. Methods: The Danish prospective, nation-wide, observational survey "Quality of life in Danish patients with multiple myeloma" (QoL-MM) (Nielsen LK et al. PMID: 30656677) framed our study. In QoL-MM, survey data are obtained at enrolment and subsequently at 12 follow-up time points over a two-year period. The following PRO questionnaires are used; the cancer-generic instrument of European Organisation for Research and Treatment of Cancer Quality of life (EORTC) QLQ-C30 (EORTC QLQ-C30), the Multiple Myeloma module QLQ-MY20 (EORTC QLQ-MY20), the Chemotherapy-Induced Peripheral Neuropathy module (EORTC QLQ-CIPN20) and the Short-form health survey version 2 (SF12v2). In the present study, a subpopulation of the QoL-MM cohort was constructed, based on the response time of the questionnaires. QoL was compared using patient-reported outcome (PRO) data obtained before and during the COVID-19 pandemic at group level. In a Danish context, first wave was defined as April to June 2020 and the second wave as November 2020 to January 2021. The QoL data were analyzed using mixed effects linear regression, with a year-period-interaction. Pre-COVID versus COVID mean domain score difference was considered evident, if the difference was both statistically significant (p-value Results: The study included 616 patients (63% newly diagnosed and 37% relapsed) with a mean age of 68.2 years (standard deviation, 9.2); 40% were females; 76% were married/cohabiting, and 24% single. Questionnaire completion rates during the investigated periods were between 96% and 97%. In total, 1,685 completed sets of questionnaires were included in the analyses. The patients reported no statistically significant and clinically relevant difference in QoL during the first and second waves of the COVID-19 pandemic, compared to one year earlier, see table 1. When analyzing the subpopulations, we found that patients below 65 years reported improved physical health summaries (p-value 0.016), decreased fatigue (p-value < 0.001), less insomnia (p-value 0.002) and improved role functioning (p-value Conclusion: As a group, Danish patients with MM did not report impaired QoL during the COVID-19 pandemic. In contrary, we observed improvements in some domains in patients below 65 years. Our observations indicate that the patients with MM have felt cared for and in good hands during the first and second waves of the COVID-19 pandemic. However, part of the reason for our finding of no negative impact on QoL by the pandemic could be that the questionnaires used were not developed to capture the impact of the pandemic on QoL. Importantly, our results suggest that QoL data collected in clinical trials during the pandemic allow interpretation without adjusting for the impact of the pandemic. Figure 1 Figure 1.

Purpose The quality of patient-reported outcome (PRO) data can be compromised by non-response (NR) to scheduled questionnaires, particularly if reasons for NR are related to health problems, which may lead to unintended bias. The aim was to investigate whether electronic reminders and real-time monitoring improve PRO completion rate. Methods The population-based study “Quality of life in Danish multiple myeloma patients” is a longitudinal, multicentre study with consecutive inclusion of treatment-demanding newly diagnosed or relapsed patients with multiple myeloma. Education of study nurses in the avoidance of NR, electronic reminders, 7-day response windows and real-time monitoring of NR were integrated in the study. Patients complete PRO assessments at study entry and at 12 follow-up time points using electronic or paper questionnaires. The effect of the electronic reminders and real-time monitoring were investigated by comparison of proportions of completed questionnaires before and after each intervention. Results The first 271 included patients were analysed; of those, 249 (85%) chose electronic questionnaires. Eighty-four percent of the 1441 scheduled PRO assessments were completed within the 7-day response window and 11% after real-time monitoring, achieving a final PRO completion rate of 95%. A significant higher proportion of uncompleted questionnaires were completed after the patients had received the electronic reminder and after real-time monitoring. Conclusions Electronic reminders and real-time monitoring contributed to a very high completion rate in the study. To increase the quality of PRO data, we propose integrating these strategies in PRO studies, however highlighting that an increase in staff resources is required for implementation.
