Identifying drivers of first-line HR+/HER2- metastatic breast cancer treatment choices.

Aim: Assess factors associated with first-line (1L) treatment for HR+/HER2- metastatic breast cancer. Materials & methods: A cross-sectional survey of 250 US oncologists was conducted. Correlations were calculated between treatment class and demographics, treatment perceptions and other clinical/nonclinical characteristics. Results: Efficacy and safety/tolerability were critical in oncologists' 1L decision-making. CDK4/6i use positively correlated with proportion of Medicare and postmenopausal patients (r = 0.54-0.67). Chemotherapy use demonstrated positive correlations with perimenopausal and premenopausal patients and symptom burden (r = 0.31-0.42). Aromatase inhibitor (AI) monotherapy correlated positively with anticipated treatment compliance (r = 0.42). Conclusion: Efficacy and safety/tolerability were most important to 1L decision-making. Clinical characteristics corresponded with CDK4/6i and chemotherapy use. Anticipated compliance was associated with AI monotherapy use.

Patients in the USA with a certain type of metastatic breast cancer (mBC, i.e., HR+/HER2−) might get chemotherapy or hormone therapy alone instead of new and potentially better medicines called cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) as their first treatment.Researchers wanted to understand how US cancer specialists decided the first treatment for this type of mBC. In a survey of 250 cancer specialists, researchers looked at different factors that might influence decision-making, including patient characteristics, doctors' opinions about the treatments and other medical and non-medical features. This study also examined the connections between these factors and the cancer specialists' choice of first treatment.Researchers found that cancer specialists care most about how well a treatment works and how safe it is when choosing the first treatment for HR+/HER2− mBC. They are more likely to use CDK4/6i if their patients have Medicare coverage or are older (i.e., women who have been through menopause). Chemotherapy is chosen if their patients are younger (i.e., women who are near and before menopause) or have more symptoms. Cancer specialists tend to choose first treatment with hormone therapy alone if they think their patients have a hard time following their treatment plan. The results showed that patient characteristics, doctors' opinions of treatments and other medical and non-medical factors play a role in choosing treatment for HR+/HER2− mBC. By understanding these factors, researchers can work toward improving treatment choices for patients with this type of mBC.

Patient characteristics and outcomes associated with nitrovasodilator use in the treatment of acute heart failure.

Nitrovasodilators (NVs) are commonly recommended for the treatment of acute heart failure (AHF); however, registries suggest their use is not common. The objectives of this study were to determine patient characteristics associated with NV use and to explore the association between NV use and outcomes [length of stay (LoS) and inpatient mortality] in patients with AHF. A survey of US physicians (n = 426) who treat at least 5 AHF patients per month with NV provided a patient sample (n = 812 treated with NV and n = 322 not-NV) derived from chart review. Factors associated with NV use as well as patient characteristics and outcomes associated with NV use were explored using bivariate analysis, logistic regression, and negative binomial regression as appropriate. NV-treated patients were more likely to be female, have a higher systolic blood pressure, higher B-type natriuretic peptide and troponin, and stay in the intensive care unit while hospitalized, but less likely to be hyponatremic or hospitalized once previously. Overall, average LoS was 5.10 days (SD = 4.52) with 5.21 days (SD = 0.15) for the NV group and 4.94 days (SD = 0.31) for the non-NV group. The overall inpatient mortality rate was 2.1%. Among physicians who frequently use NV to treat AHF patients, there are distinct patient characteristics between NV treated and nontreated patients, suggesting a phenotype-driven approach. However, no differences in LoS or mortality were observed.

Preferences for a Clostridioides difficile vaccine among adults in the United States.

INTRODUCTION: Clostridioides difficile (C.diff) infection (CDI) causes significant morbidity and mortality among older adults. Vaccines to prevent CDI are in development; however, data on the target population's preferences are needed to inform vaccination recommendations in the United States (US). This study assessed US adults' willingness to receive a C.diff vaccine and examined how vaccine attributes influence their choices. METHODS: A cross-sectional online survey with a discrete choice experiment (DCE) was conducted among US adults aged ≥50 years. DCE attributes included effectiveness, duration of protection, reduction in symptom severity, out-of-pocket (OOP) costs, number of doses, and side effects. The DCE included 11 choice tasks, each with two hypothetical vaccine profiles and an opt-out (i.e., no vaccine). Attribute-level preference weights were estimated using hierarchical Bayesian modeling. Attribute relative importance (RI) was compared between select subgroups. RESULTS: Of 1216 adults in the analyses, 29.9% reported they knew either 'a little' (20.7%) or 'a lot' (9.2%) about C.diff before the study. A C.diff vaccine was chosen 58.0% of the time (vs. opt-out) across choice tasks. It was estimated that up to 75.0% would choose a vaccine when OOP was $0. Those who were immunocompromised/high-risk for CDI (vs. not) more frequently chose a C.diff vaccine. Decreases in OOP costs (RI = 56.1), improvements in vaccine effectiveness (RI = 17.7), and reduction in symptom severity (RI = 10.3) were most important to vaccine choice. The rank ordering of attributes by importance was consistent across subgroups. CONCLUSION: OOP cost, improvements in vaccine effectiveness, and reduction in CDI severity were highly influential to vaccine selection. Most adults aged ≥50 years were receptive to a C.diff vaccine, especially with little-to-no OOP cost, suggesting that mandating insurance coverage of vaccination with no copayment may increase uptake. The limited awareness about C.diff among adults presents an opportunity for healthcare providers to educate their patients about CDI prevention.

Patient experience and unmet needs in high-risk nonmuscle-invasive bladder cancer: Insights from qualitative interviews and a cross-sectional survey.

OBJECTIVES: To evaluate patient experience, unmet needs, and burden among patients with high-risk nonmuscle-invasive bladder cancer (HR-NMIBC) treated with Bacillus Calmette-Guérin (BCG). METHODS: This cross-sectional study included HR-NMIBC patients who received BCG treatment in the past 3 years. The study, preceded by a focused literature review, was conducted in 2 phases: 1) qualitative interviews with 32 patients in the United States (US), France, Germany, and United Kingdom (UK) and 2) quantitative survey of 150 patients in the US. Both phases of the study assessed patient characteristics, treatment history, experience, and perceptions, as well as side effects, pain, discomfort, and time burden associated with BCG treatment. The quantitative survey included additional items related to BCG treatment satisfaction, health-related quality of life (HRQoL), productivity, and healthcare resource utilization. Descriptive statistics and bivariate subgroup comparisons were reported. RESULTS: All patients in both study phases received transurethral resection of the bladder tumor (TURBT). Nearly all patients reported keeping their bladder/avoiding radical cystectomy (RC) was important (99%). Results from the quantitative survey reported a substantial impact to cancer-specific HRQoL of patients, with lower mean scores on physical (64.7), social (62.8), and role functioning (56.7) as measured by the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-30). Most patients (69%) were satisfied overall with BCG treatment, although satisfaction declined with increased number of side effects, higher numbers of BCG administrations, and greater discomfort (all P < 0.05). CONCLUSIONS: Most HR-NMIBC patients were satisfied overall with BCG treatment. Approximately half of the patients had stopped BCG treatment, notably, most during the induction phase, suggesting nonadherence to guidelines which recommend maintenance treatment after induction. Future treatments should focus on delaying or avoiding recurrence and cystectomy while reducing patient discomfort and discontinuation prior to completing the recommended course of treatment.

Healthcare Providers' and Pregnant People's Preferences for a Preventive to Protect Infants from Serious Illness Due to Respiratory Syncytial Virus.

We assessed the impact of respiratory syncytial virus (RSV) preventive characteristics on the intentions of pregnant people and healthcare providers (HCPs) to protect infants with a maternal vaccine or monoclonal antibodies (mAbs). Pregnant people and HCPs who treated pregnant people and/or infants were recruited via convenience sample from a general research panel to complete a cross-sectional, web-based survey, including a discrete choice experiment (DCE) wherein respondents chose between hypothetical RSV preventive profiles varying on five attributes (effectiveness, preventive type [maternal vaccine vs. mAb], injection recipient/timing, type of medical visit required to receive the injection, and duration of protection during RSV season) and a no-preventive option. A best-worst scaling (BWS) exercise was included to explore the impact of additional attributes on preventive preferences. Data were collected between October and November 2022. Attribute-level preference weights and relative importance (RI) were estimated. Overall, 992 pregnant people and 310 HCPs participated. A preventive (vs. none) was chosen 89.2% (pregnant people) and 96.0% (HCPs) of the time (DCE). Effectiveness was most important to preventive choice for pregnant people (RI = 48.0%) and HCPs (RI = 41.7%); all else equal, pregnant people (RI = 5.5%) and HCPs (RI = 7.2%) preferred the maternal vaccine over mAbs, although preventive type had limited influence on choice. Longer protection, protection starting at birth or the beginning of RSV season, and use for both pre-term and full-term babies were ranked highest in importance (BWS). Pregnant people and HCPs strongly preferred a preventive to protect infants against RSV (vs. none), underscoring the need to incorporate RSV preventives into routine care.

A latent class analysis of factors influencing preferences for infant respiratory syncytial virus (RSV) preventives among pregnant people in the United States.

A maternal vaccine and long-acting monoclonal antibody (mAb) were recently approved to protect infants against respiratory syncytial virus (RSV). We identified subgroups of pregnant people with different preferences for RSV preventives and respondent characteristics associated with subgroup membership. An online survey, including a discrete choice experiment (DCE), was conducted among US pregnant people. RSV preventive attributes included effectiveness, duration of protection during RSV season, injection recipient/timing, preventive type (vaccine or mAb), and type of visit required to receive injection. In DCE choice tasks, pregnant people selected between two hypothetical preventive profiles with varying attribute-levels and a no-preventive option. Logistic regression, including latent class analysis (LCA), was used to analyze the data. Of 992 pregnant people (mean age: 30.0 years), 60.3% were expecting their second/later birth. LCA identified three preference subgroups: 'Effectiveness' (preventive choice mostly driven by increases in effectiveness; 51.4% class membership probability), 'Season' (preventive choice mostly driven by improvement in duration of protection during the RSV season; 39.2% class membership probability), and 'No Preventive' (frequently chose no-preventive option; 9.4% class membership probability). 'Effectiveness' and 'Season' preferred maternal vaccine over mAb; mAb was preferred by 'No Preventive.' Perceiving RSV as serious for infants, higher health literacy, and lower household income were associated with 'Effectiveness.' Perceiving RSV as serious for pregnant people was associated with 'Season.' Perceiving RSV to not be serious for pregnant people and not being employed were associated with 'No Preventive.' Subgroups of pregnant people vary in preferences for RSV preventives. Most pregnant people preferred a maternal vaccine, although some may be more willing to accept alternative preventive options.

Survey of the use of warfarin and the newer anticoagulant dabigatran in patients with atrial fibrillation.

BACKGROUND: Oral dabigatran was recently approved as an alternative to warfarin for prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. Unlike warfarin, dabigatran has a fixed dosage and few drug interactions, and does not require anticoagulation monitoring or dietary restrictions. METHODS: This study aimed to describe and compare characteristics of patients with atrial fibrillation who used dabigatran or only warfarin. Patients with a self-reported diagnosis of atrial fibrillation aged ≥18 years who were receiving (or had received) warfarin or dabigatran completed an online survey. Differences in characteristics of dabigatran and warfarin users were tested using chi-squared tests and analysis of variance for categorical and continuous variables, respectively. RESULTS: Overall, 364 patients were surveyed (204 warfarin users, 160 dabigatran users). The mean age was 65.1 years, and 68.7% were male. Dabigatran users were more likely than warfarin users to be female (36.9% versus 27.0%) and to have experienced adverse events, including gastrointestinal bleeding, in the 3 months before the survey (21.9% versus 6.9%; P<0.05). Both groups reported high medication adherence (dabigatran users 0.65 versus warfarin users 0.63 missed doses/month). Dabigatran users were more likely than warfarin users to discuss treatment options with their physician before beginning therapy (36.9% versus 24.5%; P<0.05) and less likely to switch anticoagulant medication (10.7% versus 31.9%; P<0.05). Although dabigatran users were more likely to experience adverse events, they reported greater satisfaction with anticoagulation treatment than warfarin users. CONCLUSION: The efficacy and convenience reported by dabigatran users resulted in greater treatment satisfaction among dabigatran users, even though adverse events decreased it. Treatment strategies that minimize adverse events may improve treatment satisfaction and adherence among patients with atrial fibrillation.

The Patient-Related Burden of Pegylated-Interferon-α Therapy and Adverse Events among Patients with Viral Hepatitis C in Japan.

OBJECTIVES: Pegylated-interferon-α (IFN-α)-based therapies for viral hepatitis C (HCV) are effective, but they are associated with several adverse events (AEs). The primary objectives of this study were to quantify the burden of IFN-α-based treatment and to measure the prevalence and burden of IFN-α-related AEs in Japan. METHODS: A cross-sectional survey was administered online to patients with HCV in 2013. Patients who were currently taking IFN-α-based therapy (n = 188) were compared with patients who were taking a liver protectant but not IFN-α-based therapy (n = 180) and with patients who were untreated (n = 365) on measures of health-related quality of life (using the Hepatitis Quality of Life Questionnaire, version 2), work productivity, and health care resource use, controlling for sociodemographic characteristics and health history. Among patients taking IFN-α-based therapy, the prevalence and burden of AEs was examined on the same set of health outcomes as noted above along with treatment satisfaction and adherence. RESULTS: Compared with untreated patients, patients using IFN-α reported poorer health-related quality of life (physical component summary score, 50.13 vs. 52.04; mental component summary score, 44.12 vs. 47.97), more overall work impairment (32.73 vs. 25.64), more physician visits in the past 6 months (14.51 vs. 8.36), and an increased likelihood of an emergency room visit (odds ratio = 7.25) and hospitalization (odds ratio = 4.05) (all P < 0.05). The mean number of AEs was 6.05 for patients using IFN-α. All AEs were associated with poorer health outcomes (particularly the mental component summary score), and most were also associated with lower treatment satisfaction and medication adherence. CONCLUSIONS: A significant patient burden for IFN-α treatment itself and various AEs was observed. The results suggest that effective, non-IFN-α-based treatments may reduce the societal burden.

Impact of the severity of vasomotor symptoms on health status, resource use, and productivity.

OBJECTIVE: The current study characterizes health-related quality of life, work productivity, and resource use among postmenopausal women by severity of vasomotor symptoms (VMS). METHODS: Participants were selected from the 2010 US National Health and Wellness Survey. Women aged 40 to 75 years who did not report a history of menstrual bleeding or spotting for 1 year were eligible for analysis (N = 3,267). Cohorts of women with no VMS (n = 1,740), mild VMS (n = 931), moderate VMS (n = 462), and severe VMS (n = 134) were compared after controlling for demographic and health characteristics. Outcome measures were assessed using linear models and included health status, work productivity within the past 7 days, and healthcare resource use within the past 6 months. RESULTS: The mean age of women experiencing severe VMS was 57.92 years. After demographic and health characteristics had been controlled for, women experiencing severe and moderate VMS reported significantly lower mean health status scores compared with women with no symptoms (P < 0.0001). The mean number of menopause symptom-related physician visits was significantly greater among women with severe, moderate, or mild symptoms than among women with no symptoms (P < 0.0001). Among employed women experiencing VMS, women with severe and moderate symptoms had adjusted presenteeism of 24.28% and 14.3%, versus 4.33% in women with mild symptoms (P < 0.001), and activities of daily living impairment of 31.66% and 17.06%, versus 6.16% in women with mild symptoms (P < 0.0001). CONCLUSIONS: In postmenopausal women, a greater severity of VMS is significantly associated with lower levels of health status and work productivity, and greater healthcare resource use.
