The association between social determinants of health and patient-centred outcomes in adults with heart failure with reduced ejection fraction.

AIMS: To explore the associations between social determinants of health and patient-centred outcomes among adults with chronic heart failure with reduced ejection fraction. DESIGN: Cross-sectional online self-report survey. METHODS: A survey assessing social determinants of health (demographics, socio-economic position, affordability of care and social support) and patient-centred outcomes, including the Kansas City Cardiomyopathy Questionnaire-12 and validated measures of medication adherence, treatment satisfaction, treatment burden and mental health, was completed by 512 adults with chronic heart failure with a reduced ejection fraction between 06 March and 29 June 2020. Multivariable analyses included linear and logistic regression. RESULTS: Female gender, having a care partner, and being offered financial assistance with medications were associated with worse health status, while perceiving medication as affordable and being married were associated with better health status. Females and having Medicaid, dual Medicaid/Medicare or no medical insurance were associated with a higher likelihood of depression, and non-white race/ethnicity was associated with less depression. Medication adherence was lower in patients having a care partner and offered financial assistance. Patients being offered financial and medication management assistance were more likely to be overwhelmed by the treatment burden, whereas those having some college education were less so. CONCLUSIONS: Social determinants of health are associated with patients' disease-specific health status, mental health and treatment satisfaction and burden. These findings underscore the importance of assessing social determinants of health in clinical practice and the need for developing and testing novel strategies to determine whether they improve patients' health. IMPACT: The relationship between social determinants of health- and patient-centred outcomes was assessed; affordability of care and social support factors were most strongly associated with outcomes for patients with chronic heart failure and reduced ejection fraction, underscoring the importance of assessing social determinants of health in routine clinical care. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Social determinants of health data could potentially inform care delivery for patients with heart failure and reduced ejection fraction by helping to identify those who require additional support to manage their symptoms, access care and adhere to treatment. Social support and affordability of treatment were associated with most patient-centred outcomes, suggesting these factors may provide clinicians with an indicator of a patient's level of general well-being that could be assessed during routine follow-up care. REPORTING METHOD: This research followed the STROBE checklist for cross-sectional studies. PATIENT OR PUBLIC CONTRIBUTION: Adults who have heart failure with reduced ejection fraction that consented to participate in the study provided the data used for all analyses reported on in the manuscript. Service users, caregivers or members of the public had no involvement in the study.

Suboptimal adherence to food restrictions requirements related to drug regimens for chronic diseases.

BACKGROUND: Oral medications for chronic conditions often involve a variety of instructions, including time of day/dosing, drug interactions, and food intake restrictions. However, the extent to which patients follow these instructions is unclear. METHODS: We surveyed patients from the US and Europe (UK, France, Germany, Italy, Spain) who were prescribed sulfonylureas (SU: glimepiride, glipizide, or gliclazide) for diabetes or levothyroxine for hypothyroidism. Patients kept a daily diary for 3-5 days documenting their adherence to three criteria: dosing regimen including time of day, warning labels including drug interactions, and food restrictions. RESULTS: A total of 421 US and 493 European patients took the study medications; 546 patients took SU and 368 took levothyroxine. Overall, 48% of patients were males; 46% were age 65 years or older. Despite most patients having received instructions on medication requirements (US 71%, EU 75%), most patients reported being only somewhat knowledgeable (US 69%; EU 71%). Adherence, measured by the proportion of the days a participant was adherent to each category out of the observational period (ranging from 3-5 days), varied by type of instruction, with the poorest adherence observed for food restriction requirements (US 34% of the observation days, EU 26%) compared to warning labels (US 77%, EU 67%) and dosing regimen (US 85%, EU 87%). CONCLUSIONS: Patients adhered to dosing and cautionary instructions across the majority of the study period but were largely non-adherent to food intake restrictions. Improved communication and increased emphasis on food intake restrictions is needed when advising patients on their medications.

Understanding the Burdens Associated with Huntington's Disease in Manifest Patients and Care Partners-Comparing to Parkinson's Disease and the General Population.

BACKGROUND: The study provides real-world data on the impact of Huntington's disease (HD) from the perspective of individuals with HD (IHD) and care partners (HD-CP) and contextualizes these results relative to Parkinson's disease (PD) and the general population (GP). METHODS: Cross-sectional survey of IHD and HD-CP in the US (July 2019-August 2019) conducted using the Rare Patient Voice panel. Data for individuals with Parkinson's Disease (IPD), the general population (GP), and respective care partners (PD-CP; GP-CP) came from the 2018 US National Health and Wellness Survey. Outcomes included demographics, mental health, clinical characteristics, and health-related quality of life (HRQoL). RESULTS: IHD had greater comorbid anxiety (IHD = 51.2%, IPD = 28.8%, GP = 2.0%), and HD-CP had greater comorbid anxiety (HD-CP = 52.5%, PD-CP = 28.6%, GP-CP = 19.6%) and depression (HD-CP = 65.0%, PD-CP = 29.9%, GP-CP = 19.6%), relative to other cohorts (p < 0.05). Respective of their GP cohorts, IHD exhibited lower HRQoL (EQ-5D: 0.66 ± 0.21 vs. 0.81 ± 0.17) and greater depression (PHQ-9: 11.59 ± 7.20 vs. 5.85 ± 6.71), whereas HD-CP exhibited greater depression only (PHQ-9: 6.84 ± 6.38 vs. 4.15 ± 5.58) (p < 0.001). No differences were observed between HD/HD-CP and PD/PD-CP cohorts on PHQ-9 or HRQoL. CONCLUSIONS: HD has a significant burden on patients and care partners, which is higher than GP. Notably, anxiety and depression were greater among HD vs. PD, despite similar HRQoL.

Patient-centered Outcomes in HFrEF Following a Worsening Heart Failure Event: A Survey Analysis.

BACKGROUND: Heart failure is a chronic disease punctuated by intermittent exacerbations that require hospitalization or intravenous diuretic therapy. The association of worsening heart failure events (WHFEs) with patient-centered outcomes in heart failure with reduced ejection fraction (HFrEF) remains unexplored. METHODS AND RESULTS: Patients with HFrEF completed an online survey assessing health status, medication adherence, treatment satisfaction, treatment burden, and medication costs and affordability. Patients with and without WHFEs were compared on all study variables, with adjustment for patient characteristics using linear or logistic regression. Overall, 512 patients (52.0% WHFEs) were included. Patients with WHFEs more commonly had depression (55.3% vs 24.0%), anxiety (46.2% vs 17.9%), and insomnia (77.8% vs 44.7%; P < 0.001 for all). Patients with WHFEs had lower adjusted mean Kansas City Cardiomyopathy Questionnaire values (52.9 vs 56.0) and Satisfaction with Medications Questionnaire values (70.5 vs 72.6) and higher Treatment Burden Questionnaire scores (51.1 vs 45.1; P < 0.001). Medication-related beliefs and long-term concerns were independently associated with nonadherence in patients with WHFE (adjusted odds ratios: 4.2 and 5.2, respectively; P < 0.01 for both). Patients with WHFE incurred 50.0% higher median monthly out-of-pocket HF prescription medication costs and less often perceived HF medications to be affordable. CONCLUSIONS: WHFE is associated with several adverse impacts on patients with HFrEF. Additional support is warranted to manage symptoms, comorbidities, and HF treatments to improve adherence and outcomes.
