The lived experience of patients with breast cancer on adjuvant endocrine therapy: side effects and coping strategies during the first year of medication initiation.

PURPOSE: Adjuvant endocrine therapy (AET) is pivotal for hormone receptor-positive breast cancer patients, significantly enhancing survival rates. Yet, adherence to AET remains challenging due to side effects. This study delves into the lived experience of breast cancer survivors concerning AET-induced side effects and examines differences in symptom profiles between Tamoxifen and aromatase inhibitors (AIs). METHODS: We interviewed 35 breast cancer survivors on AET, conducting qualitative iterative analysis using grounded theory. A codebook was developed to aid data coding and interpretation. NVIVO software facilitated comprehensive transcript analysis. RESULTS: Survivors reported a spectrum of side effects like hot flashes, sexual issues, joint pain, stiffness, mood swings, and fertility concerns. Symptom profiles differed based on AET type. Tamoxifen users experienced more frequent sexual side effects and mood swings, while AIs were linked to joint pain, stiffness, and bone health worries. Those on AET for over 6 months expressed heightened concerns about side effects. CONCLUSION: Tailored patient education, aligned with AET type, empowers survivors to manage side effects using self-regulatory strategies. Acknowledging distinct symptom profiles enables informed decisions, improving adherence and quality of life. IMPLICATIONS: This study underscores tailored survivorship support, equipping patients with tools to manage side effects, enhancing adherence, and long-term outcomes. The findings inform the integration of comprehensive survivorship programs, emphasizing individualized strategies for managing side effects and promoting better adherence and improved quality of life.

Emergency Department Use in Black Individuals With Diabetes.

Objective: The prevalence of diabetes is higher in Black than in White individuals, and Blacks seek emergency department (ED) care for diabetes more often than Whites. This randomized controlled trial compared the efficacy of a novel intervention called the Diabetes Interprofessional Team to Enhance Adherence to Medical Care (DM I-TEAM) to usual medical care (UMC) to prevent return diabetes-related ED visits and hospitalizations over 12 months in 200 Black individuals with diabetes after an ED visit. The trial also identified baseline variables associated with return ED visits and hospitalizations. Methods: The DM I-TEAM provided diabetes education and behavioral activation services delivered by race-concordant research assistants, telehealth visits with a diabetes care and education specialist and primary care physicians, and clinical pharmacist recommendations. Results: Participants had a mean age of 64.9 years, and 73.0% were women. There was no treatment group difference in return diabetes-related ED visits or hospitalizations over 12 months (DM I-TEAM n = 39 [45.3%] vs. UMC n = 37 [38.5%], χ2 = 0.864, P = 0.353). Baseline variables that were associated with return diabetes-related ED visits or hospitalizations were longer duration of diabetes, higher number of chronic health conditions, higher number of previous ED visits or hospitalizations, greater anticholinergic medication burden, lower satisfaction with primary care physicians, and lower trust in physicians (all P ≤0.05). Conclusion: Among Black individuals with diabetes, the DM I-TEAM interprofessional intervention was no better than UMC at preventing return diabetes-related ED visits or hospitalizations. High medical morbidity, greater anticholinergic medication burden, low satisfaction with primary care physicians, and physician mistrust were associated with diabetes-related ED visits or hospitalizations independent of treatment. Before clinical interventions such as the DM I-TEAM can be effective, reducing system-level barriers to health, improving physician-patient relationships and medication prescribing, and building community health care capacity will be necessary.

Association of Polypharmacy and Potentially Inappropriate Medications With Physical Functional Impairments in Older Adults With Cancer.

BACKGROUND: Polypharmacy and potentially inappropriate medications (PIMs) are prevalent in older adults with cancer, but their associations with physical function are not often studied. This study examined the associations of polypharmacy and PIMs with physical function in older adults with cancer, and determined the optimal cutoff value for the number of medications most strongly associated with physical functional impairment. METHODS: This cross-sectional analysis used baseline data from a randomized study enrolling patients aged ≥70 years with advanced cancer starting a new systemic cancer treatment. We categorized PIM using 2015 American Geriatrics Society Beers Criteria. Three validated physical function measures were used to assess patient-reported impairments: activities of daily living (ADL) scale, instrumental activities of daily living (IADL) scale, and the Older Americans Resources and Services Physical Health (OARS PH) survey. Optimal cutoff value for number of medications was determined by the Youden index. Separate multivariate logistic regressions were then performed to examine associations of polypharmacy and PIMs with physical function measures. RESULTS: Among 439 patients (mean age, 76.9 years), the Youden index identified ≥8 medications as the optimal cutoff value for polypharmacy; 43% were taking ≥8 medications and 62% were taking ≥1 PIMs. On multivariate analysis, taking ≥8 medications was associated with impairment in ADL (adjusted odds ratio [aOR], 1.64; 95% CI, 1.01-2.58) and OARS PH (aOR, 1.73; 95% CI, 1.01-2.98). PIMs were associated with impairments in IADL (aOR, 1.72; 95% CI, 1.09-2.73) and OARS PH (aOR, 1.97; 95% CI, 1.15-3.37). A cutoff of 5 medications was not associated with any of the physical function measures. CONCLUSIONS: Physical function, an important component of outcomes for older adults with cancer, is cross-sectionally associated with polypharmacy (defined as ≥8 medications) and with PIMs. Future studies should evaluate the association of polypharmacy with functional outcomes in this population in a longitudinal fashion.

Associations of Polypharmacy and Inappropriate Medications with Adverse Outcomes in Older Adults with Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Polypharmacy (PP) and potentially inappropriate medications (PIM) are highly prevalent in older adults with cancer. This study systematically reviews the associations of PP and/or PIM with outcomes and, through a meta-analysis, obtains estimates of postoperative outcomes associated with PP in this population. MATERIALS AND METHODS: We searched PubMed, Embase, Web of Science, and Cochrane Register of Clinical Trials using standardized terms for concepts of PP, PIM, and cancer. Eligible studies included cohort studies, cross-sectional studies, meta-analyses, and clinical trials which examined outcomes associated with PP and/or PIM and included older adults with cancer. A random effects model included studies in which definitions of PP were consistent to examine the association of PP with postoperative complications. RESULTS: Forty-seven articles met the inclusion criteria. PP was defined as five or more medications in 57% of the studies. Commonly examined outcomes included chemotherapy toxicities, postoperative complications, functional decline, hospitalization, and overall survival. PP was associated with chemotherapy toxicities (4/9 studies), falls (3/3 studies), functional decline (3/3 studies), and overall survival (2/11 studies). A meta-analysis of four studies indicated an association between PP (≥5 medications) and postoperative complications (overall odds ratio, 1.3; 95% confidence interval [1.3-2.8]). PIM was associated with adverse outcomes in 3 of 11 studies. CONCLUSION: PP is associated with postoperative complications, chemotherapy toxicities, and physical and functional decline. Only three studies showed an association between PIM and outcomes. However, because of inconsistent definitions, heterogeneous populations, and variable study designs, these associations should be further investigated in prospective studies. IMPLICATIONS FOR PRACTICE: Polypharmacy and potentially inappropriate medications (PIM) are prevalent in older adults with cancer. This systematic review summarizes the associations of polypharmacy and PIM with health outcomes in older patients with cancer. Polypharmacy and PIM have been associated with postoperative complications, frailty, falls, medication nonadherence, chemotherapy toxicity, and mortality. These findings emphasize the prognostic importance of careful medication review and identification of PIM by oncology teams. They also underscore the need to develop and test interventions to address polypharmacy and PIM in older patients with cancer, with the goal of improving outcomes in these patients.

The role of oncology pharmacists and comprehensive medication reconciliation in informing treatment plans for older adults with cancer and downstream outcomes.

PURPOSE OF REVIEW: Proper medication management is an essential part of older adult cancer care. An aging population, an increase in anticancer treatment options, and high rates of comorbid conditions make navigating general medication reconciliation complicated. This review will highlight the recent literature describing the roles of the oncology pharmacist in caring for older adults with cancer. RECENT FINDINGS: The body of literature highlighting oncology pharmacist roles in this population is mainly focused on polypharmacy and potentially inappropriate medication assessments, deprescribing nonessential therapies, drug-drug interaction reviews, and immunization optimization. Outcomes associated with oncology pharmacist interventions are still lacking as well as the development of benchmarks for appropriate pharmacy-based care in the older adult oncology population. SUMMARY: Oncology pharmacist interventions in older adults with cancer have the potential to improve patient care. Future randomized studies in this area of practice are warranted in order to clearly define the optimal impact of oncology pharmacists.

The lived experience of breast cancer patients on adjuvant endocrine therapy: Side effects and coping strategies during the first year of medication initiation.

Purpose: Breast cancer in women is the most commonly diagnosed cancer. Adjuvant endocrine therapy (AET) showed consistent improvements in recurrence and survival rates. Adherence to adjuvant endocrine therapy remains essential for improving overall survival in women with hormone receptor (HR) positive breast cancer. However, early discontinuation of medicine is reported to range from 20% to 50%. Poor adherence has been attributed to multiple factors including presence of adverse events. We aim to report the lived experience of breast cancer survivors specifically as regards to side effects, the most reported reason for lack of adherence. Methods: 35 breast cancer survivors on AET were interviewed. Qualitative iterative analysis was conducted using the grounded theory approach with the goal of identifying themes that emerge from the interviews and refining the question probes as needed. A codebook was developed and supplemented with interpretive codes generated through ongoing analysis of transcripts. All transcripts were coded using NVIVO qualitative data analysis software for data interpretations. Results: Reported side effects associated with AET medications include hot flashes, sexual side-effects, joint pain, stiffness, cognitive function, mood changes, bone mass density decrease and fertility concerns. Women who were on AET more than 6 months reported more side effect concerns. A variety of coping strategies using over the counter medications or alternative medicines and approaches were also discussed. Conclusion: Tailored and timely information on potential AET-induced side effects and strategies to manage them is needed. In particular, some side effects are more prevalent by medication (e.g., joint pain in those who were taking an aromatases inhibitor). Provision of information to prepare women for the potential side effects of type of AET they are prescribed for would be helpful. Implications for Cancer Survivors: As AET has been suggested for 10 years to improve surveillance and reduce recurrence, our results have implications for cancer survivors, especially the onsets of side effects and potential ways to manage them as they arise.

Interprofessional Intervention to Reduce Emergency Department Visits in Black Individuals with Diabetes.

Black individuals with diabetes have high rates of emergency department (ED) use. This randomized controlled trial compared the efficacy of Diabetes Interprofessional Team to Enhance Adherence to Medical Care (DM I-TEAM) versus Usual Medical Care (UMC) to reduce number of return ED visits/hospitalizations over 12 months in 200 Black individuals with diabetes after an ED visit. DM I-TEAM consisted of community health worker-delivered diabetes education and behavior activation, telehealth visits with a diabetes nurse educator and primary care physicians, and clinical pharmacist recommendations to reduce potentially inappropriate medications (PIMs). Secondary outcomes included glycemic control, PIMs use, diabetes self-management, diabetes self-efficacy, depression, and medical trust. Participants had a mean age of 64.9 years and 73.0% were women. The 2 treatment groups were similar in baseline characteristics. Sixty-eight (69.4%) DM I-TEAM participants and 69 (67.6%) UMC participants had at least 1 incident ED visit/hospitalization over 12 months. The adjusted incidence rate ratio for DM I-TEAM versus UMC was 1.11 (95% confidence interval 0.79-1.56; P = 0.54). DM I-TEAM participants attained significantly better diabetes self-management, diabetes self-efficacy, and institutional trust than UMC participants. There were no treatment group differences in hemoglobin A1c level nor PIMs use. Among Black individuals with diabetes, a novel culturally relevant intervention was no better than usual care at preventing return ED visits/hospitalizations over 1 year. Before reasonable clinical interventions such as DM I-TEAM can be effective, reducing system-level barriers to health, building community health care capacity, and designing interventions that better align with the everyday realities of patients' lives are necessary. clinicaltrials.gov NCT03393338.

Cabazitaxel (jevtana): a novel agent for metastatic castration-resistant prostate cancer.

OBJECTIVE: This article presents current clinical evidence supporting the use of cabazitaxel (Jevtana) in men with metastatic castration-resistant prostate cancer (mCRPC). DATA SOURCES: We conducted a literature search using abstracts from MEDLINE and PubMed (from January 1966 to December 2011) and the American Society of Clinical Oncology (from January 2000 to December 2011). The search included clinical studies and abstracts in the English language that described the pharmacology, pharmacokinetics, clinical activity, and safety of cabazitaxel in mCRPC. RESULTS: Cabazitaxel, a semisynthetic microtubule inhibitor that induces cell death by microtubule stabilization, was approved in combination with prednisone for the treatment of mCRPC in patients who had been treated with a docetaxel-(Taxotere)-containing regimen. The approval of this taxane derivative was based primarily on the results of a randomized, open-label trial in patients with mCRPC who were treated with either cabazitaxel 25 mg/m(2) or mitoxantrone (Novantrone) 12 mg/m(2) intravenously every 3 weeks, both in combination with prednisone 10 mg/day. The median survival period was 15.1 months with cabazitaxel and 12.7 months with mitoxantrone. Neither group experienced complete responses. Cabazitaxel has also shown activity in breast cancer and other malignancies. In clinical trials, common grade 3 or grade 4 adverse reactions were myelosuppression, febrile neutropenia, diarrhea, fatigue, and asthenia. Other adverse effects included abdominal pain, back pain, arthralgia, and peripheral neuropathy. CONCLUSION: Cabazitaxel appeared to be an effective second-line agent in patients with mCRPC refractory to a docetaxel-containing regimen. Studies comparing cabazitaxel with existing first-line regimens for mCRPC are under way. Until the results of these head-to-head trials are published, it remains uncertain whether cabazitaxel is more effective or more tolerable than the currently available first-line regimens.

Polypharmacy in older adults with cancer undergoing radiotherapy: A review.

Polypharmacy is characterized by the simultaneous use of multiple medications, including prescription drugs, over-the-counter drugs, and nutritional supplements. Polypharmacy is known to increase the risk of adverse drugs reactions, drug-drug interactions, and medication errors, and to negatively impact quality of life. The prevalence of polypharmacy varies by population, but has been reported to exceed 90% among older adults with cancer. Polypharmacy may be exacerbated among older adults with cancer receiving radiation therapy due to the resulting acute or chronic side effects that need to be managed with additional medications. The medications prescribed to manage radiation-related side effects increase the risk of adverse drug events, as do changes in nutritional status related to the secondary side effects of radiation treatment. Side effects from treatment may result in the need for breaks in cancer therapy or treatment delays, which ultimately can lead to worse oncologic outcomes. Few studies have examined polypharmacy in the context of older adults undergoing radiation therapy. We sought to review the literature pertaining to polypharmacy among older adults with cancer and discuss implications specifically for those individuals undergoing radiation therapy. This paper presents a narrative review of studies published in the past decade that provided detailed information on polypharmacy in older adults undergoing radiation therapy for cancer. The review elucidated good practices to avoid adverse drug events from polypharmacy, but more studies are warranted to develop standard guidelines.

Polypharmacy and Potentially Inappropriate Medication Use in Older Blacks with Diabetes Mellitus Presenting to the Emergency Department.

Background: Medication-related problems in older Blacks with diabetes mellitus (DM) are not well established. Objectives: To describe the frequency of medication-related problems in older Blacks with DM presenting to the emergency department (ED). Methods: The study was a cross-sectional analysis of baseline data from a randomized controlled trial evaluating Blacks aged ≥60 years of age presenting to the ED. Polypharmacy, potentially inappropriate medication (PIM) use, and anticholinergic score were evaluated. Results: Of 168 patients (median age = 68, range 60-92), most (n = 164, 98%) were taking ≥5 medications, and 67 (39.9%) were taking a PIM. A majority (n = 124, 74%) were taking a medication with an anticholinergic score ≥1. Number of medications was correlated with number of PIMs (r = .22, p = .004) and anticholinergic score (r = .50, p < .001). Conclusion: Polypharmacy and PIM use was common in older Blacks with DM.

Ofatumumab: a novel anti-CD20 monoclonal antibody for treatment of refractory chronic lymphocytic leukemia.

OBJECTIVE: To present the current clinical evidence on ofatumumab for use in refractory chronic lymphocytic leukemia (CLL). DATA SOURCES: A literature search was performed using MEDLINE and PubMed (both 1966-May 2011), as well as the American Society of Hematology abstracts (2000-May 2011), using the primary search terms ofatumumab and HuMax-CD20. STUDY SELECTION AND DATA EXTRACTION: Clinical studies and abstracts available in the English language, describing the pharmacology, pharmacokinetics, clinical activity, and safety of ofatumumab in CLL were included in this review. DATA SYNTHESIS: Ofatumumab is a human immunoglobulin monoclonal antibody that binds to B-lymphocytes expressing CD-20 cell surface antigens. Ofatumumab was granted accelerated approval by the Food and Drug Administration in October 2009 for the treatment of CLL refractory to fludarabine and alemtuzumab. A Phase 1/2 trial has established the safety and tolerability of single-agent ofatumumab at an initial dose of 300 mg intravenously on week 1, followed by 2000 mg once weekly for 7 doses (weeks 2-8), followed by 2000 mg once every 4 weeks for 4 doses (weeks 9-12), for a total of 12 doses. The final analysis of a pivotal international multicenter trial has shown promising activity in patients with CLL refractory to fludarabine and alemtuzumab, demonstrating overall response rates of 44-51%, with prolonged progression-free and overall survival. Ofatumumab activity has also been shown in a variety of other malignant and nonmalignant conditions, including non-Hodgkin lymphoma, rheumatoid arthritis, and multiple sclerosis. The most common adverse effect is grade 1 and 2 infusion reactions. Other adverse effects include infection, neutropenia, anemia, rash, fever, and diarrhea. CONCLUSIONS: Clinical evidence suggests that ofatumumab is an effective agent in patients with CLL refractory to fludarabine and alemtuzumab. Data are awaited comparing ofatumumab to other salvage regimens. Until results of head-to-head trials are conducted comparing ofatumumab to existing regimens, it cannot be said whether ofatumumab is more efficacious or tolerable than currently available therapies.

Managing Polypharmacy in Older Adults with Cancer Across Different Healthcare Settings.

The care of older patients with cancer is becoming increasingly complex. Common challenges for this population include management of comorbidities, safe transitions of care, and appropriate medication use. In particular, polypharmacy-generally defined as the regular use of five or more medications-and inappropriate medication use can lead to adverse effects and poor outcomes in older adults with cancer, including falls, hospital readmissions, cognitive impairment, poor adherence to essential medications, chemotherapy toxicity, and increased mortality. Managing polypharmacy across different cancer care settings is often challenging. Providers face barriers to safe and successful medication management that may include lack of time, absence of reimbursement, underappreciation of the scale of polypharmacy-related harm, lack of ownership of deprescribing efforts, and poor communication across care settings. Existing literature on managing inappropriate medication use and polypharmacy in older adults with cancer has often focused on ideal state settings in which resources are plentiful and time is purposefully allocated for medication interventions. This paper presents a narrative, rather than a systematic review, of studies published in the past decade that provided detailed information on medication management and polypharmacy across cancer care settings. This review aims to also summarize different healthcare provider roles in taking action against inappropriate medication use and polypharmacy in older adults with cancer.

Interventions to reduce polypharmacy and optimize medication use in older adults with cancer.

The use of polypharmacy and potentially inappropriate medications (PIMs) is an increasingly common, concerning public health issue in older adults, and a concurrent cancer diagnosis only further escalates the prevalence and complexity. Polypharmacy and PIM use has been associated with negative patient outcomes, including falls, chemotherapy toxicities and other adverse events, postoperative complications, frailty, functional impairment, and shortened survival. Despite the recognition of the harms, the prevalence of polypharmacy and PIM use continues to rise due to a lack of standardized identification and intervention methods. Efforts to reduce the prevalence have included use of explicit PIM screening tools (e.g., Beers criteria), comprehensive medication reviews, and deprescribing algorithms. However, these efforts are not widespread and the research on the effectiveness of such interventions is limited. To better understand what is known, this paper summarized available studies evaluating the effect of interventions on reducing the burden of polypharmacy/PIMs and provided recommendations to guide further practice models to reduce the negative consequences associated with polypharmacy and PIM use. Furthermore, we aim to establish a framework for clinical practice and to highlight areas for future intervention-based research to improve outcomes for older adults with cancer.

Research priorities to address polypharmacy in older adults with cancer.

Polypharmacy poses a significant public health problem that disproportionately affects older adults (≥65 years) since this population represents the largest consumers of medications. Clinicians caring for older adults with cancer must rely on evidence to understand polypharmacy and its implications, not only to communicate with patients and other healthcare providers, but also because of the significant interplay between polypharmacy, cancer, cancer-related treatment, and clinical outcomes. Interest in polypharmacy is rising because of its prevalence, the origins and facilitating factors behind it, and the direct and indirect clinical outcomes associated with it. The growing body of publications focused on polypharmacy in older adults with cancer demonstrates that this is a significant area of research; however, limited evidence exists to guide medication use (e.g., prescribing, administration) in this population. Currently, research priorities aimed at polypharmacy in the field of geriatric oncology lack clarity. We identified current gaps in the literature in order to establish research priorities for polypharmacy in older adults with cancer. The five research priorities-Polypharmacy Methodology and Definitions, Suboptimal Medication Use, Comorbidities and Geriatric Syndromes, Underrepresented Groups, and Polypharmacy Interventions-highlight critical areas for future research to improve outcomes for older adults with cancer.

Perspectives on functional status in older adults with cancer: An interprofessional report from the International Society of Geriatric Oncology (SIOG) nursing and allied health interest group and young SIOG.

Most adults with cancer are over 65 years of age, and this cohort is expected to grow exponentially. Older adults have an increased burden of comorbidities and risk of experiencing adverse events on anticancer treatments, including functional decline. Functional impairment is a predictor of increased risk of chemotherapy toxicity and shorter survival in this population. Healthcare professionals caring for older adults with cancer should be familiar with the concept of functional status and its implications because of the significant interplay between function, cancer, anticancer treatments, and patient-reported outcomes. In this narrative review, we provide an overview of functional status among older patients with cancer including predictors, screening, and assessment tools. We also discuss the impact of functional impairment on patient outcomes, and describe the role of individual members of an interprofessional team in addressing functional impairment in this population, including the use of a collaborative approach aiming to preserve function.

Mortality and Hospitalization Risk Following Oral Androgen Signaling Inhibitors Among Men with Advanced Prostate Cancer by Pre-existing Cardiovascular Comorbidities.

BACKGROUND: Elderly patients (≥65yr) with advanced prostate cancer and cardiovascular disease (CVD) conditions are often excluded from clinical trials of abiraterone acetate (AA) or enzalutamide (ENZ). Consequently, little is known about the effects of these medications on these vulnerable patients. OBJECTIVE: To assess the short-term outcomes of AA and ENZ in patients with pre-existing CVDs. DESIGN, SETTING, AND PARTICIPANTS: A population-based retrospective study. The Surveillance, Epidemiology, and End Results-Medicare-linked database was used to identify prostate cancer patients using AA or ENZ. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was 6-mo all-cause mortality, analyzed using modified Poisson regression modeling of relative risk (RR) adjusted for confounders and comorbidities. RESULTS AND LIMITATIONS: Among eligible patients (2845 with AA and 1031 with ENZ), 67% had at least one pre-existing CVD. Compared with those without pre-existing CVDs, having one to two pre-existing CVDs was associated with 16% higher 6-mo mortality (RR=1.16, 95% confidence interval [CI]: 1.00-1.36), and the risk increased further among those having three or more CVDs (RR=1.56, 95% CI: 1.29-1.88). Most of the differences in survival of patients with pre-existing CVD condition occurred within the first 6mo of treatment. CONCLUSIONS: After treatment with AA or ENZ, elderly prostate cancer patients with pre-existing CVDs experienced higher short-term mortality than otherwise similar patients without CVDs. Mortality associated with CVDs did not depend on having received AA versus ENZ. PATIENT SUMMARY: Patients with pre-existing cardiovascular diseases (CVDs) experienced higher short-term mortality after abiraterone acetate or enzalutamide than those without pre-existing CVDs. It is recommended that a multidisciplinary team, including a cardiologist, evaluate patients having pre-existing CVDs in the process of making treatment decisions and monitoring potential side effects.

Relationship between polypharmacy and inpatient hospitalization among older adults with cancer treated with intravenous chemotherapy.

OBJECTIVES: Polypharmacy (≥5 concurrent medications) is common among older patients with cancer (48%-80%) and associated with increased frailty, morbidity, and mortality. This study examined the relationship between polypharmacy and inpatient hospitalization among older adults with cancer treated with intravenous (IV) chemotherapy. MATERIALS AND METHODS: The main data source was the Surveillance, Epidemiology, and End Results-Medicare linked files. Patients (≥65 years) were included if they were diagnosed with prostate (n = 1430), breast (n = 5490), or lung cancer (n = 7309) in 1991-2013 and received IV chemotherapy in 2011-2014. The number of medications during the six-month window pre-IV chemotherapy initiation determined polypharmacy status. Negative binomial models were used to assess the association between polypharmacy and post-chemotherapy inpatient hospitalization. The results were presented as incidence rate ratios. RESULTS: We identified 13,959 patients with prostate, breast, or lung cancer treated with IV chemotherapy. The median number of prescription medications during the six-month window pre-IV chemotherapy initiation was high: ten among patients with prostate cancer, nine among patients with breast cancer, and eleven among patients with lung cancer. Compared to patients taking <5 prescriptions, post-chemotherapy hospitalization rate for patients with prostate cancer was 42%, 75%, and 114% higher among those taking 5-9, 10-14, and 15+ medications, respectively. Patients with breast and lung cancer demonstrated similar patterns. CONCLUSION: This large population-based study found that polypharmacy during the six-month window pre-IV chemotherapy is highly predictive of post-chemotherapy inpatient hospitalization. Further studies are needed to evaluate whether medication management interventions can reduce post-chemotherapy inpatient hospitalization among older patients with cancer.

A randomized clinical trial of a collaborative home-based diabetes intervention to reduce emergency department visits and hospitalizations in black individuals with diabetes.

The prevalence of diabetes mellitus (DM) in black individuals (blacks) is twice that of white individuals (whites), and blacks are more likely to have worse glycemic control, less optimal medication regimens, and higher levels of mistrust in the medical system. These three factors account for higher rates of acute medical care use in blacks with DM. To address this disparity, we developed DM I-TEAM (Diabetes Interprofessional Team to Enhance Adherence to Medical Care), a home-based multidisciplinary behavioral intervention that integrates care from a community health worker (CHW), the participant's primary care physician (PCP), a DM nurse educator, and a clinical pharmacist. Treatment is delivered during 9 sessions over 1 year, and includes diabetes education and goal setting, telehealth visits with participants' PCP and a DM nurse educator, and comprehensive medication reviews by a pharmacist. We describe the rationale and methods for a randomized controlled trial to test the efficacy of DM I-TEAM to reduce emergency department (ED) visits and hospitalizations. We are enrolling 200 blacks with DM during an ED visit. Participants are randomized to DM I-TEAM or Usual Medical Care (UMC). Follow-up assessments are conducted at 6 and 12 months. The primary outcome is the number of ED visits and hospitalizations over 12 months, and is measured by participant self-report and medical record review. Secondary outcomes include hemoglobin A1c (HbA1c), number of potentially inappropriate medications (PIMs), and trust in health care.

A Practical Guide to Geriatric Syndromes in Older Adults With Cancer: A Focus on Falls, Cognition, Polypharmacy, and Depression.

Geriatric syndromes are multifactorial conditions that are prevalent in older adults. Geriatric syndromes are believed to develop when an individual experiences accumulated impairments in multiple systems that compromise their compensatory ability. In older adults with cancer, the presence of a geriatric syndrome is common and may increase the complexity of cancer treatment. In addition, the physiologic stress of cancer and cancer treatment may precipitate or exacerbate geriatric syndromes. Common geriatric syndromes include falls, cognitive syndromes and delirium, depression, and polypharmacy. In the oncology setting, the presence of geriatric syndromes is relevant; falls and cognitive problems have been shown to be predictive of chemotherapy toxicity and overall survival. Polypharmacy and depression are more common in older adults with cancer compared with the general geriatric population. Multiple screening tools exist to identify falls, cognitive problems, polypharmacy, and depression in older adults and can be applied to the oncology setting to identify patients at risk. When recognized, several interventions exist that could be considered for this vulnerable population. We review the available evidence of four geriatric syndromes in the oncology setting, including clinical implications, validated screening tools, potential supportive care, and therapeutic interventions.

Clinical pharmacology of oncology agents in older adults: A comprehensive review of how chronologic and functional age can influence treatment-related effects.

Unique challenges exist when managing older adults with cancer. Associations between cancer and age-related physiologic changes have a direct impact on pharmacokinetics and pharmacodynamics of cancer therapies and can affect drug dosing, dose intensity, efficacy, safety and quality of life. The breadth and depth of these issues, however, have not been fully evaluated because the majority of clinical trials have focused on a younger and healthier population. As a consequence, little information is available to support clinicians in making evidence-based decisions regarding treatment with cancer therapies in older adults, especially those over age 75. Prior clinical pharmacology reviews summarized the literature on how age-related physiologic changes can influence and affect conventional and targeted anti-cancer treatments. Our article provides an updated review with expanded information that includes small molecule kinase inhibitors, monoclonal antibodies, immunotherapies, hormonal, conventional, and miscellaneous agents. Additionally, our article integrates how functional age, determined by the geriatric assessment (GA), can also influence treatment-related effects and health outcomes. Broadening cancer therapy trials to capture not only chronologic age but also functional age would allow clinicians to better identify subsets of older adults who benefit from treatment versus those most vulnerable to morbidity and/or mortality.
