Physical functioning, frailty and risks of locally-advanced breast cancer among older women.

OBJECTIVE: Women with multiple comorbidities have competing health needs that may delay screening for early detection of breast cancer. Our objective was to determine associations between physical functioning and frailty with risk of locally-advanced breast cancer (BC). METHODS: We conducted a retrospective cohort study of women 65 years and older diagnosed with first primary stage I-III BC using the Surveillance, Epidemiology and End Results Medicare Health Outcome Survey Data Resource. Physical health-related quality of life was measured using Veterans RAND 12 Item Health Survey scales within two years before diagnosis; frailty was determined by calculating deficit-accumulation frailty index (DAFI) scores. Multivariable modified Poisson regression models were used to estimate rate ratios (RR) and 95% confidence intervals (CI) for risk of locally-advanced (stage III) versus early-stage (I-II) BC. RESULTS: Among 2411 women with a median age of 75 years at BC diagnosis, 2189 (91%) were diagnosed with incident stage I-II BC and 222 (9%) were diagnosed at stage III. Compared to women with early-stage disease, women with locally-advanced BC had lower physical component scores (37.8 vs. 41.4) and more classified as pre-frail or frail (55% vs. 50%). In multivariable models, frailty was not associated with increased risk of locally-advanced disease. However, worse physical function subscale scores (lowest vs. upper quartile; RR = 1.56, 95% CI 1.04-2.34) were associated with risk of locally-advanced BC. CONCLUSIONS: Breast cancer screening among non-frail older women should be personalized to include women with limited physical functioning if the benefits of screening and early detection outweigh the potential harms.

The association between physical health-related quality of life, physical functioning, and risk of contralateral breast cancer among older women.

BACKGROUND: Physical limitations prior to cancer diagnosis may lead to suboptimal health outcomes. Our objective was to evaluate the impacts of poor physical health-related quality of life (HRQOL) and physical functioning (PF) on the risk of contralateral breast cancer (CBC). METHODS: We performed a nested case-control study of women with invasive unilateral breast cancer (UBC) who did not receive prophylactic contralateral mastectomy using the Surveillance, Epidemiology and End Results Medicare Health Outcomes Survey data resource. Among 2938 women aged ≥ 65 years diagnosed with first stage I-III UBC between 1997 and 2011, we identified 100 subsequent CBC cases and 915 matched controls without CBC using incidence density sampling without replacement. Pre-diagnosis physical HRQOL and PF were determined using Medical Outcomes Trust Short Form-36 (SF-36)/Veterans Rand 12-Item Health Survey (VR-12) responses within 2 years prior to first UBC diagnosis. We estimated adjusted odds ratios (OR) and 95% confidence intervals (CI) using conditional logistic regression models. RESULTS: Cases and controls were similar with respect to comorbidities, stage, surgery, and radiation treatments, but differed by hormone receptor status (ER/PR-negative, 23% and 11%, respectively) of first UBC. Cases had modestly lower mean pre-diagnosis physical HRQOL (- 1.8) and PF (- 2.2) scores. In multivariable models, we observed an increased CBC risk associated with low physical HRQOL (lowest vs. highest quartile, OR = 1.8; 95% CI 0.8-4.3), but CIs included 1.0. Low PF was associated with a 2.7-fold (95% CI 1.1-6.7) increased CBC risk. CONCLUSIONS: Findings indicate that low physical HRQOL, specifically poor PF, is associated with CBC risk. Efforts to understand and minimize declines in PF post-breast cancer are well motivated.

Population-based recurrence rates among older women with HR-positive, HER2-negative early breast cancer: Clinical risk factors, frailty status, and differences by race.

BACKGROUND: Multiple independent risk factors are associated with the prognosis of hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer (BC), the most common BC subtype. This study describes U.S. population-based recurrence rates among older, resected women with HR+/HER2- early BC. METHODS: We conducted a retrospective cohort study of older women diagnosed with incident, invasive stages I-III HR+/HER2- BC who underwent surgery to remove the primary tumor using the Surveillance, Epidemiology, and End Results (SEER)-Medicare Linked Database (2007-2015). SEER records and administrative health claims data were used to ascertain patient and tumor-specific characteristics, treatment, and frailty status. Cumulative incidences of BC recurrence were estimated using a validated algorithm for administrative claims data. Multivariable Fine-Gray competing risk models estimated adjusted subdistribution hazards ratios and 95 % confidence intervals for associations with BC recurrence risk. RESULTS: Overall, 46,027 women age ≥65 years were included in our analysis. Over a median follow up of 7 years, 6531 women experienced BC recurrence with an estimated 3 and 5-year cumulative incidence rates of 10 % and 16 %, respectively. Higher 3- and 5-year cumulative incidences were observed in women with larger tumor size (5+ cm, 21 % and 28 %), lymph node involvement (4+ nodes, 27 % and 37 %), and with frail health status at diagnosis (13 % and 20 %). Independent of these clinical risk factors, Black, Hispanic and American Indian/Alaskan Native women had significantly increased BC recurrence risks. CONCLUSIONS: Rates of recurrence in HR+/HER2- early BC differs by several patient and clinical factors, including high-risk tumor characteristics. Racial differences in BC outcomes deserve continued attention from clinicians and policymakers.

Associations between frailty and cancer-specific mortality among older women with breast cancer.

PURPOSE: Frailty is assessed when making treatment decisions among older women with breast cancer (BC), which in turn impacts survival. We evaluated associations between pre-diagnosis frailty and risks of BC-specific and all-cause mortality in older women. METHODS: We conducted a retrospective cohort study of Medicare beneficiaries ages ≥ 65 years with stage I-III BC using the Surveillance, Epidemiology and End Results-Medicare Health Outcome Survey Data Resource. Frailty was measured using the deficit-accumulation frailty index, categorized as robust, pre-frail, or frail, at baseline and during follow-up. Fine and Gray competing risk and Cox proportional hazards models were used to estimate subdistribution hazard ratios (SHR) and hazard ratios (HR) with 95% confidence intervals (CI) for BC-specific and all-cause mortality, respectively. RESULTS: Among 2411 women with a median age of 75 years at BC diagnosis, 49.5% were categorized as robust, 29.4% were pre-frail and 21.1% were frail. Fewer frail women compared to robust women received breast-conserving surgery (52.8% vs. 61.5%, frail vs. robust, respectively) and radiation (43.5% vs. 51.8%). In multivariable analyses, degree of frailty was not associated with BC-specific mortality (frail vs robust SHR 1.47, 95% CI 0.97-2.24). However, frail women with BC had higher risks of all-cause mortality compared to robust women with BC (HR 2.32, 95% CI 1.84-2.92). CONCLUSION: Among a cohort of older women with BC, higher degrees of frailty were associated with higher risk of all-cause mortality, but not BC-specific mortality. Future study should examine if preventing progression of frailty may improve all-cause mortality.

A comparison of medication access services at 340B and non-340B hospitals.

BACKGROUND: For patients that face barriers to filling their prescriptions, the availability of medication access services at their site of care can mean the difference between receiving prescribed drug therapy, and undue interruptions in care. Hospitals often provide medication access services that are not reimbursed by payers; however, they can be challenging to sustain. The 340B Drug Pricing Program allows covered entities to generate savings through discounted pricing for certain outpatient medications, which can then be used to provide more comprehensive services, including medication access services. OBJECTIVE: To characterize medication access services provided at hospitals that participate in the 340B Drug Pricing Program compared to hospitals that do not participate in the 340B Program. METHODS: Primary questionnaire response data was collected from a national sample of Directors of Pharmacy at non-federal acute care hospitals from March 2019 to May 2019. American Hospital Association Data Viewer was used to collect demographic information on 1,531 hospitals. Hospitals were excluded if they had 199 beds or fewer, did not have a unique Medicare provider ID, were federally owned, were located outside the continental U.S., or were non-acute care hospitals that served niche patient populations. This study utilized a proportional stratified sampling strategy to administer an electronic questionnaire to 340B and non-340B hospitals to assess the number and type of medication access service offerings. A final randomized sample of 500 hospitals were administered the questionnaire, and data was collected through recorded responses in Qualtrics software. RESULTS: 340B hospitals provided a significantly higher average number of medication access services compared to non-340B hospitals (6.20 vs. 3.91, p = 0.0001), adjusted for differences in hospital size and ownership type. For all nine medication access services that were assessed, a higher percentage of 340B hospitals reported providing the service compared to non-340B hospitals. This difference was statistically significant for six out of nine programs assessed. CONCLUSIONS: 340B hospitals provided more medication access services, on average, than comparably sized non-340B hospitals, suggesting that hospitals participating in the 340B Drug Pricing Program may be better positioned to create and administer programs that support medication access services.

Self-reported health and survival in older patients diagnosed with multiple myeloma.

PURPOSE: Patient-reported outcomes such as self-reported health (SRH) are important in understanding quality cancer care, yet little is known about links between SRH and outcomes in older patients with multiple myeloma (MM). We evaluated associations between SRH and mortality among older patients with MM. METHODS: We analyzed a retrospective cohort of patients ages ≥ 65 years diagnosed with first primary MM using the Surveillance, Epidemiology, and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) data resource. Pre-diagnosis SRH was grouped as high (excellent/very good/good) or low (fair/poor). We used Cox proportional hazards models to estimate adjusted hazard ratios (HR) and 95% confidence intervals (CI) for associations between SRH and all-cause and MM-specific mortality. RESULTS: Of 521 MM patients with mean (SD) age at diagnosis of 76.8 (6.1) years, 32% reported low SRH. In multivariable analyses, low SRH was suggestive of modest increased risks of all-cause mortality (HR 1.32, 95% CI 1.02-1.71) and MM-specific mortality (HR 1.22, 95% CI 0.87-1.70) compared to high SRH. CONCLUSION: Findings suggest that low pre-diagnosis SRH is highly prevalent among older patients with MM and is associated with modestly increased all-cause mortality. Additional research is needed to address quality of life and modifiable factors that may accompany poor SRH in older patients with MM.

Clinical pharmacists in diabetes management: What do minority patients with uncontrolled diabetes have to say?

OBJECTIVE: Clinical pharmacist support for patients with type 2 diabetes mellitus (T2DM) can optimize patient outcomes and medication adherence. However, there is limited understanding of what pharmacist roles patients perceive as most helpful in T2DM management interventions. This study describes experiences of minority patients with uncontrolled T2DM in terms of perceived pharmacist helpfulness and specific roles found to be most helpful within diabetes management. DESIGN: A secondary analysis of a 2-year randomized, crossover trial was conducted. SETTING AND PARTICIPANTS: This study included 244 African American and Hispanic adults with uncontrolled T2DM who received clinical pharmacist support within a team-based model. OUTCOME MEASURES: The patients completed a mixed-methods survey regarding their experience with the intervention that included a general helpfulness rating on a 10-point unipolar Likert scale and described the support qualitatively, including their perception of the pharmacist roles. Thematic analysis guided coding of the responses. RESULTS: One hundred forty-seven (60%) patients completed the survey and had at least 1 encounter with a clinical pharmacist. Of these, 108 (74%) were African American, 39 (27%) were Hispanic, and 101 (69%) were women. The median rating of clinical pharmacist helpfulness was 10 (very helpful). Only 10 (7%) participants rated pharmacist helpfulness as 1 (not at all helpful). "Medication education and management" was the most frequently perceived supportive role of the clinical pharmacists, followed by "non-medication-related patient education," "social support," and "care coordination." Miscommunication related to scheduling was the most common reason cited for not meeting with the clinical pharmacist. CONCLUSION: This sample of minority patients with uncontrolled T2DM recognized many roles outlined within the American Pharmacists Association Medication Therapy Management framework. Patient experiences with clinical pharmacist T2DM support are crucial for developing effective programs, maximizing patient engagement, satisfying patient needs, and ensuring that a program's intended purpose aligns with the patient perspective.
