The impact of elexacaftor/tezacaftor/ivacaftor on cystic fibrosis health-related quality of life and decision-making about daily treatment regimens: a mixed methods exploratory study.

Background: Elexacaftor/tezacaftor/ivacaftor (ETI) has reduced many symptoms of cystic fibrosis (CF). Objectives: We sought to identify the impact of ETI on both symptoms and treatment decisions among adults with CF. Design: Participants were enrolled in a cross-sectional study. Surveys were sent via a RedCap link. Semistructured interviews were administered remotely via Microsoft Teams. Interviews were audio recorded and professionally transcribed. Methods: We assessed Cystic Fibrosis Questionnaire-Revised (CFQ-R) subscales for physical, respiratory, emotion, and treatment, and analyzed semistructured interviews covering CF treatment regimens and daily living. Quantitative and qualitative results were analyzed separately and via a mixed-methods convergence coding matrix. Results: Twenty-four adults with CF taking ETI were included. CFQ-R subscale scores (mean scores/standard deviation) were physical (82.1/22.8), respiratory (83.7/11.2), emotion (65.3/14.2), and treatment (57.5/20.1). Three themes about decision-making for non-ETI-treatments emerged: (1) How I'm feeling, (2) Not noticing a difference, and (3) Uncertainty about long-term impact of modifying treatment regimens, and we found participants weighed each of these factors in their treatment decisions. Key findings from mixed-methods analysis show that among individuals experiencing higher CFQ-R scores for physical and respiratory compared to emotion and treatment, there were statements indicating that while those participants were experiencing better physical health, many continued their burdensome treatment regimens. Conclusion: With little long-term data on the impact of reducing non-ETI treatments, participants weighed how they were feeling, treatment efficacy beliefs, and risk tolerance when making treatment decisions.

The impact of Trikafta on CF health, health-related quality of life, and treatment adherence People with cystic fibrosis may be experiencing many health benefits from taking Trikafta, leading some people to cut back on or stop their other non-Trikafta treatments. We explored the impact of Trikafta on CF health, health-related quality of life, and treatment adherence for people with CF currently taking Trikafta. We compared health-related quality of life subscales from the CF Questionnaire-Revised questionnaire focused on physical symptoms, respiratory symptoms, treatment burden, and emotional well-being to assess whether people with CF were experiencing improved physical and respiratory health compared to emotional health and feelings of treatment burden. We found that many people were feeling better physically, but were still experiencing poor mental health and high treatment burden. We then looked at results from open-ended interviews to see if our qualitative data could explain the differences in the health-related quality of life scores. We found that while people were feeling better physically, many people were still continuing with the pre-Trikafta treatment regimens which may explain why physical health and respiratory health scores were higher than emotional well-being and treatment burden scores. At this time, we believe that more research is needed to guide treatment decisions related to cutting back or stopping burdensome treatment regimens.

Palliative care needs among outpatient adults with cystic fibrosis: Baseline data from the Improving Life with CF trial.

BACKGROUND: Little is known about the burden of illness experienced by people with cystic fibrosis (pwCF) since the advent of CF transmembrane conductance regulator (CFTR) modulator therapies. Studies that characterize the nature of illness burden are needed to inform the development and implementation of palliative care programs that can serve this population and address quality of life concerns. METHODS: Adults with CF treated at five U.S. CF centers were surveyed to obtain baseline data for the Improving Life with CF primary palliative care implementation trial. Consenting patients completed the Integrated Palliative Care Outcome Scale (IPOS), a multidimensional measure of unmet needs for palliative care. Sociodemographic and clinical information was also obtained. The associations among these variables were examined through bivariate and multivariable analyses. RESULTS: Among 256 adults, the most distressing symptoms included not feeling "at peace", communication difficulties with family/friends, anxiety over illness or its treatment, and a lack of energy. In the multivariable analyses, CFTR modulator use was associated with lower IPOS total and physical symptoms scores; female sex and increased hospitalizations were associated with higher scores. Increased age and history of distal intestinal obstructive syndrome were associated with higher IPOS physical symptoms scores. CONCLUSIONS: These findings illuminate the nature of illness burden for pwCF in the era of CFTR modulator therapies. Although illness burden is positively affected by modulator therapy, there is a continuing need for palliative care to address physical, emotional, and spiritual distress, and the communication and practical needs experienced by adults with CF.

The clinical impact of the Covid-19 pandemic first wave on patients with cystic fibrosis in New York.

BACKGROUND: People with cystic fibrosis (pwCF) may be at risk of complications from COVID-19 but the impact of COVID-19 on pwCF remains unknown. METHODS: We conducted a multicenter retrospective cohort study to assess the impact of the COVID-19 pandemic first wave on pwCF in the New York metropolitan area (NY) from March 1, 2020 to August 31, 2020. Objectives were to determine (1) the prevalence of COVID-19 by PCR and IgG antibody testing, (2) the clinical characteristics of COVID-19, (3) delay in routine outpatient care, and (4) the effect on anxiety and depression in pwCF. RESULTS: There were 26 COVID-19 cases diagnosed by PCR or antibody testing among the study cohort of 810 pwCF. The prevalence of COVID-19 by PCR (1.6%) and IgG antibody (12.2%) testing was low. 58% of cases were asymptomatic and 82% were managed at home. 8% were hospitalized and 1 person died. 89% of pwCF experienced delay in care. The prevalence of anxiety increased from 43% baseline to 58% during the pandemic (P<0.01). In post-hoc analysis, the proportion of patients with diabetes (38% versus 16%, P<0.01) and pancreatic insufficiency (96% versus 66%, P<0.01) were higher while CFTR modulator use was lower (46% versus 65%, P = 0.05) in pwCF who tested positive for COVID-19. CONCLUSIONS: The prevalence of COVID-19 among pwCF in NY during the pandemic first wave was low and most cases were managed at home. CFTR modulators may be protective. PwCF experienced delay in routine care and increased anxiety.

Using qualitative methods to inform the design of a decision aid for people with advanced cystic fibrosis: The InformedChoices CF patient decision aid.

OBJECTIVE: To assess information needs of adults with Cystic Fibrosis and their families toward designing a patient decision aid about invasive mechanical ventilation (IMV) and lung transplant. METHODS: Focus groups and in-depth interviews explored participants' knowledge, prior clinical conversations, and decisions about IMV and lung transplant. Interviews and focus groups were recorded and transcribed for analysis. RESULTS: N = 24 participants were recruited. Themes identified were: prior communication with clinicians, decision-making process, and living with CF. Participants having prior conversations with CF clinicians regarding: lung transplant (N = 17/74%), and IMV (N = 3/13%). Most 15(65%) felt it was important to hear patients' real-life experience, others (3/13%) relied on their CF doctors for information. Most people (16/70%) believed hearing prognosis was helpful, but 5(22%) found this information frightening. High degrees of social isolation and a desire for more interaction with other CF adults were found. CONCLUSIONS: Qualitative methods helped identify areas important for decision making about IMV and LT for CF adults. Future directions include usability and feasibility testing of the decision aid. PRACTICE IMPLICATIONS: Because IMV is rarely discussed with CF adults, clinicians might approach this topic, as with transplant, as lung function begins to decline. CF-care teams should also foster CF patient-level information exchange.
