RESUMO
PURPOSE: Globally, cancer drug expenditure exceeds $185 in US dollars (USD) billion, with the United States contributing $75 (USD) billion. Many cancer drug doses are calculated on the basis of body weight or body surface area, which often results in leftover drug in partially used single-dose vials (SDVs). The cost of wasted drug is a huge financial burden on the US health care system. We evaluated the cost savings resulting from the reduction of SDV wastage, achieved through the implementation of automated dose rounding rules in electronic health records (EHRs). METHODS: Mayo Clinic implemented automated dose rounding rules within the EHR. These rules were designed to round calculated doses to the nearest SDV if the vial size closely matched the original calculated dose, within a 10% threshold. We assessed doses administered between January 2019 and December 2021, and computed cost-savings, waste reduction, and cost of waste for chemotherapy drugs. RESULTS: In 3 years, 36.1% of doses were rounded down, 35.8% were rounded up, and 28.1% were exact doses. By rounding doses down to a vial size, we achieved cost-savings of $39.75 (USD) million and prevented 62,065 SDV of cancer drugs from going to waste. By rounding doses up, we avoided wasting $9.95 (USD) million worth of drugs. However, there were still instances where the rounding fell outside of the 10%, resulting in wasted drugs worth $25 (USD) million. CONCLUSION: The substantial burden imposed on patients and the US health care system because of cancer drug wastage is of significant concern. Although the automated dose rounding system represents a partial solution for this issue, a comprehensive approach involves the imperative development of policy and legislative solutions to effectively mitigate the challenges associated with cancer drug waste.
RESUMO
PURPOSE: Daratumumab is an anti-CD38 monoclonal antibody used to treat multiple myeloma and light chain amyloidosis. Because daratumumab may cause reactions after intravenous or subcutaneous (SC) administration, the manufacturer labeling recommends administration of premedications before every dose. Given incidence of infusion reactions appears to be rare after cycle 1, in April 2022, the Mayo Clinic implemented a practice change in which premedications were omitted from all daratumumab order sets after completion of cycle 1. This study investigated the safety of this practice. METHODS: A retrospective chart review at the Mayo Clinic reviewed eligible patients with multiple myeloma or amyloid light-chain (AL) amyloidosis who received their first dose of daratumumab within the 4 months preceding the date of implementation (preimplementation group) or no more than 4 months after (postimplementation group) the date of implementation on April 13, 2022. Data were collected only from the first eight once per week doses of daratumumab. The primary outcome was the incidence of infusion-related reactions. Data analyzed used descriptive statistics. RESULTS: Nearly all patients (95.9%) received daratumumab by SC route of administration. Of the 97 patients in the preimplementation group, >90% received premedications throughout cycles 1 and 2, and five patients (5.2%) experienced infusion reactions. Of 72 patients in the postimplementation group, <20% received premedications during cycle 2 and three patients (4.2%) experienced infusion reactions. All infusion reactions occurred within the first daratumumab cycle, indicating elimination of cycle 2 premedications did not cause any infusion reactions. No patient experienced more than one infusion reaction. CONCLUSION: Omission of premedications after cycle 1 of daratumumab did not increase the incidence of infusion. Premedications may safely be omitted after cycle 1 of daratumumab when administered by the SC route.
RESUMO
Background: Pharmacist order verification is a critical step in ensuring medication safety for patients. While the second pharmacist verification (SPV) before dispensing anticancer therapies has been a longstanding practice, its continued necessity in the context of modern electronic health systems lacks robust evidence. Objective: This study aimed to assess the frequency of interventions performed by a second pharmacist to determine the ongoing effectiveness of the SPV process. Methods: This retrospective chart review was conducted at the Mayo Clinic, encompassing all anticancer therapy orders that necessitated an SPV. The study period extended from January 1, 2019, to June 30, 2021, and included inpatient and outpatient anticancer orders. The quantification and reporting of alterations made to discrete order fields subsequent to initial pharmacist verification of clinical significance were performed, utilizing the total number of anticancer therapy orders as the denominator. Results: Approximately 300 000 anticancer therapy orders were screened for inclusion criteria and 2.6% (N = 7634) of orders were modified on the SPV. Most changes were in the categories of rate (N = 1962), order start time (N = 1219), and pharmacy communication note (N = 777). Dosing changes greater than 10% accounted for 0.03% (N = 99) of the orders, with 10 anticancer therapies responsible for more than 50% of these changes. Conclusion and relevance: This study represents the largest report on the impact of SPV in a modern era. Our results suggest the SPV may be valuable for a small proportion of chemotherapy orders but raises questions about the necessity for broad application of this practice.

INTRODUCTION: A new dosing schedule for the oncology immunotherapy pembrolizumab, every 6 weeks (Q6W), has been approved by the U.S. FDA, reducing the frequency of visits to infusion centers. We quantified the time spent by oncologists, nurses, patients, and caregivers per melanoma-related immunotherapy infusion visit to evaluate its potential impact. METHODS: Surveys were self-completed by 100 oncologists, 101 oncology nurses, and 100 patients with melanoma across the U.S. to quantify the time spent per infusion visit with pembrolizumab (Q3W or Q6W), nivolumab (Q2W or Q4W), or nivolumab+ipilimumab (nivolumab in combination: Q3W; nivolumab maintenance: Q2W or Q4W). Time measures included traveling, waiting, consultation, infusion, post-treatment observation, and caregiving. Respondents were also surveyed regarding the impact of the COVID-19 pandemic on infusion treatments. RESULTS: Responses deemed valid were provided by 89 oncologists, 93 nurses, and 100 patients. For each new [returning] patient treated with pembrolizumab, nivolumab or nivolumab+ipilimumab, oncologists reported to spend an average of 90 [64], 87 [60] and 101 [69] minutes per infusion visit (p-value for between-group difference = 0.300 [0.627]). For first [subsequent] treatment cycles, nurses reported spending 160 [145] average minutes per visit for nivolumab+ipilimumab, versus roughly 120 [110] for the single agents (p-value for between-group difference = 0.018 [0.022]). Patients reported to spend an average of 263, 382, and 224 minutes per visit at the center for pembrolizumab (N = 47), nivolumab (n = 34), and nivolumab+ipilimumab (n = 15) respectively (p-value for between-group difference = 0.0002). Patients also reported that their unpaid (N = 20) and paid caregivers (N = 41) spent with them an average of 966 and 333 minutes, respectively, from the day before to the day after the infusion visit. CONCLUSION: Less frequent immunotherapy infusion visits may result in substantial time savings for oncologists, nurses, patients, and caregivers.

PURPOSE: Median duration of daratumumab (DARA) administration for treatment of multiple myeloma is 3-7 hours for the intravenous formulation (DARA IV) and 3-5 minutes for the subcutaneous formulation (DARA SC). Here, we describe clinical administration characteristics of DARA using a novel method for data extraction from electronic health records. METHODS: Time-based measurements were extracted using a scheduling/pharmacy software program that tracked patient movement through appointments for patients initiating DARA in Mayo Clinic infusion centers from April 5, 2017, to October 14, 2021. Cohorts included patients who received DARA IV or DARA SC, or converted from DARA IV to DARA SC. The DARA SC cohort was further analyzed before (DARA SC initial) and after (DARA SC shortened) a reduction in the postadministration observation time mandated by the treatment plan. Events associated with administration-related reactions (ARRs) were also identified. RESULTS: Median total clinic times were 2.7-3.0 hours shorter for DARA SC versus DARA IV. Median clinic times were highest at dose 1 and decreased with subsequent doses. Median total chair times were 2.7-2.8 hours shorter for DARA SC versus DARA IV. Incidences of ARR-related events with DARA SC were low across doses. CONCLUSION: Reduced clinic times were observed with DARA SC, indicating that use of DARA SC as a treatment option results in time savings that may free clinic resources. Furthermore, novel methods of electronic health record data extraction can provide insights that may help inform clinic resource optimization.

INTRODUCTION: Prioritization and acuity tools have been leveraged to facilitate targeted and efficient clinical pharmacist interventions. However, there is a lack of established pharmacy-specific acuity factors in the ambulatory hematology/oncology setting. Therefore, National Comprehensive Cancer Network's Pharmacy Directors Forum conducted a survey to establish consensus on acuity factors associated with hematology/oncology patients that are high priority for ambulatory clinical pharmacist review. METHODS: A three-round electronic Delphi survey was conducted. During the first round, respondents were asked an open-ended question to suggest acuity factors based on their expert opinion. Respondents were then asked in the second round to agree or disagree with the compiled acuity factors, in which those with ≥75% agreement were included in the third round. The final consensus was defined as a mean score ≥3.33 on a modified 4-point Likert scale (4 = strongly agree, 1 = strongly disagree) during the third round. RESULTS: A total of 124 hematology/oncology clinical pharmacists completed the first round of the Delphi survey (invitation response rate, 36.7%), of which 103 completed the second round (response rate, 83.1%) and 84 the third round (response rate, 67.7%). A final consensus was achieved for 18 acuity factors. Acuity factors were identified in the following themes: antineoplastic regimen characteristics, drug interactions, organ dysfunction, pharmacogenomics, recent discharge, laboratory parameters, and treatment-related toxicities. CONCLUSIONS: This Delphi panel of 124 clinical pharmacists achieved consensus on 18 acuity factors that would identify a hematology/oncology patient as a high priority for ambulatory clinical pharmacist review. The research team envisions incorporating these acuity factors into a pharmacy-specific electronic scoring tool.

Background: Many health care organizations offer pediatric infusions in outpatient infusion centers or, as in our organization, in a hospital-based outpatient Pediatric Infusion Therapy Center (PITC). When restrictions related to the COVID-19 pandemic decreased our PITC appointment capacity by 40%, other patient and family satisfaction issues were exacerbated. We implemented a new approach to pediatric infusions with the aim of improving patient and family satisfaction and reducing the amount of time in an appointment itinerary without negatively affecting patient safety. Methods: Our team used a phased approach to pilot the administration of short chemotherapy infusions in the same outpatient clinic examination rooms where consultation and routine office visits were conducted. Patients saw their specialist for an examination and, if clinically indicated, their infusion was administered in the same room. Appointment itineraries were then completed. The team tracked efficiency, satisfaction, and safety metrics related to the new process. Results: All efficiency metrics improved. No harm came to the 49 unique patients who received a total of 184 infusions. Patient appointment itineraries were shortened by an average of 1.03â hr. Satisfaction survey responses indicated a clear preference (93%) for the new process. Discussion: The novel approach of offering short infusions in outpatient clinic examination rooms provides an opportunity to ease capacity constraints and further increase patient and family satisfaction. This method may be especially helpful for health care organizations when external influences (e.g., lack of physical space, challenging patient volumes, and pandemics) necessitate a change.

OBJECTIVE: To determine whether the formation of a multidisciplinary team, pharmacist-led therapeutic interchange, and streamlined electronic health record optimization improved biosimilar adoption throughout Mayo Clinic. PATIENTS AND METHODS: The project focused on the use of reference products and biosimilars for 5 biologics-bevacizumab, epoetin alfa, filgrastim, rituximab, and trastuzumab-at all Mayo Clinic locations. Pharmaceutical wholesale purchase histories of those reference products and biosimilars were assessed from September 1, 2020, through August 31, 2021, and compared with data from September 1, 2019, through August 31, 2020. Formulary decisions were implemented across 5 biologics for most ordering pathways on September 1, 2020. Pharmaceutical purchased drug units and expenditures were tracked at 3-month intervals for conversion to formulary-preferred contracted biosimilars. RESULTS: In the final postimplementation period, the absolute percentage increase of formulary-preferred biosimilars was 69% for bevacizumab, 63% for epoetin alfa, 80% for filgrastim, 79% for rituximab, and 72% for trastuzumab. Pharmaceutical line item savings in the 12-month postimplementation period totaled $23.1 million across all 5 biologics. CONCLUSION: Creation of a multidisciplinary team to implement formulary-preferred contracted biosimilars led to the adoption of biosimilars throughout Mayo Clinic with considerable pharmaceutical line item savings.

PURPOSE: To evaluate the prevalence of burnout among hematology-oncology pharmacists and factors associated with an increased risk of high burnout. METHODS: Between October and November 2020, members of the Hematology/Oncology Pharmacy Association were invited to complete an anonymous survey. Questions included the Maslach Burnout Inventory (MBI), Well-Being Index, and sociodemographic and occupational factors linked with burnout. RESULTS: Of 3,024 pharmacists contacted, 614 pharmacists (20.3%) responded to an online survey and 550 (18.2% of overall sample) completed the MBI and were included for analysis. Overall, high levels of burnout were observed in 61.8% of respondents based on the MBI, with 57.9% of respondents scoring high on the emotional exhaustion domain and 31.3% high in the depersonalization domain. Pharmacists with burnout worked on average 48.6 (±9.6) hours per week compared with 44.5 (±9.6) hours per week for those without high burnout and spent more time on administrative tasks per week (7.5 hours v 4.3 hours; all P < .001). Pharmacists reporting high burnout were more likely to report concern they had made a major medication error within the past 3 months (27.6% v 8.1%; P < .001) and greater intent to leave their current job within 2 years (60.3% v 19.0%; P < .001). CONCLUSION: Burnout is prevalent among hematology-oncology pharmacists and may affect both patient safety and the adequacy of the workforce. Risk factors for burnout among hematology-oncology pharmacists in this study may be targets for burnout mitigation and prevention strategies to reduce the impact on pharmacists and improve cancer care for patients.

PURPOSE: To describe the development of an innovative process to deliver bacillus Calmette-Guérin (BCG) to an offsite urology clinic for bladder instillation. SUMMARY: The use of BCG, a live virus vaccine for treatment of patients with localized cancer of the urinary bladder, has created many logistical problems for hospitals and infusion center pharmacies. Due to its short stability, the drug cannot be made ahead of time and coordination with a patient's arrival at an infusion site is challenging. This becomes exceptionally challenging when a urology clinic has limited compounding capacity and/or is distant from the site of BCG medication preparation. This article describes an innovative process involving use of closed-system transfer devices (CSTDs) to allow for the administration of BCG in a urology clinic offsite from a medical center's infusion center facilities. CONCLUSION: The use of the CSTD allowed the patients to continue to receive bladder instillations at an offsite urology clinic without significantly disrupting compounding workflow at the small infusion center pharmacy that was the nearest to the clinic.

Pancreatic cancer is typically diagnosed in the late stage of the disease, making it the fourth leading cause of cancer-related death in the United States. It is also one of the few cancers with an increasing incidence, particularly in the younger population. By 2030, it is expected to become the second leading cause of cancer-related death. Patients with pancreatic cancer encounter monthly medical costs 15 times higher than those without, with costs highest in the later stages of the disease. Treatments for pancreatic cancer include surgery (available to fewer than 20% of newly diagnosed patients) and, for advanced disease, chemotherapy with gemcitabine with nab-paclitaxel or FOLFIRINOX, which can increase overall survival (OS) by a few months. Economic and outcome analyses of clinical data find no significant difference in OS between the 2 regimens, although FOLFIRINOX carries a much higher rate of serious adverse effects, limiting its use to patients with good performance status. In 2017, the FDA approved immunotherapy for patients with microsatellite instability-high or mismatch repair-deficient solid tumors, which occurs in approximately 1% of pancreatic cancer diagnoses. Several immunotherapies and targeted therapies are currently in clinical trials and may significantly alter the trajectory of the disease. However, they typically cost more than $100,000 per year, putting significant strain on payers. Thus, it is important that payers plan now for the potential arsenal of new treatments and identify opportunities to manage their utilization as well as patients with the disease to contain costs.

Managing chemotherapy-induced nausea and vomiting (CINV) is an opportunity for better clinical, economic, and humanistic outcomes. Clinicians working in managed care settings must understand background information about CINV's causes, likelihood, and treatment. They need to understand how CINV creates collateral damage (eg, psychological effects, electrolyte disturbances, dehydration, malnutrition, and esophageal injury). Patients with CINV are costly to treat and may be unable or unwilling to continue chemotherapy at doses needed. Several guidelines offer recommendations for selecting appropriate antiemetic medications. Most managed care organizations use or encourage their oncology staffs to use established guidelines. A trend is to tailor guidelines to address institution-specific policies, procedures, and idiosyncrasies. Patients receiving guideline-directed care for CINV tend to have better outcomes. Prophylaxis and treatment for CINV must be patient specific and consider risk factors that increase the likelihood of nausea and vomiting or, conversely, decrease the likelihood. Managed care clinicians should know that most of the guidelines do not include patient-specific factors in their prediction models for CINV. Although research has indicated that clinicians tend to underestimate and undertreat CINV, some research has indicated that clinicians can be too aggressive when providing prophylaxis for various types of CINV. Patient education is the cornerstone of good treatment planning, and educating patients on how and when to report symptoms is critical. Tools are available to help patients track symptoms. The multidisciplinary team must ensure that patients receive prophylaxis and appropriate treatment for their diagnoses, as well as treatment plans.

Significant enthusiasm currently exists for new immunotherapeutic strategies: blocking the interaction between programmed death-1 receptor on T-cells and programmed death-ligand 1 on tumor cells to boost immune system stimulation to fight cancer. Immunomodulation with the antiprogrammed death-1/programmed death-ligand 1 monoclonal antibodies has shown to mediate tumor shrinkage and extend overall survival from several pivotal phase I/II studies in melanoma, renal cell carcinoma, and non-small cell lung cancer. This has prompted multiple large ongoing phase III trials with the expectation for fast-track FDA approvals to satisfy unmet medical needs. Compounds targeting the programmed death-1 pathway that are in clinical trials fall into two major categories, namely antiprogrammed death-1 antibodies: Nivolumab, MK-3475, and pidilizumab; and antiprogrammed death-ligand 1 antibodies: MPDL3280A, BMS-936559, MEDI4736, and MSB0010718C. We reviewed the clinical efficacy and safety of each compound based upon major registered clinical trials and published clinical data. Overall, response rate of more than 20% is consistently seen across all these trials, with maximal response of approximately 50% achieved by certain single antiprogrammed death-1 agents or when used in combination with cytotoxic T-lymphocyte antigen-4 blockade. The responses seen are early, durable, and have continued after treatment discontinuation. Immune-related adverse events are the most common side effects seen in these clinical trials. Overall, the skin and gastrointestinal tract are the most common organ systems affected by these compounds while hepatic, endocrine, and neurologic events are less frequent. These side effects are low grade, manageable, and typically resolve within a relatively short time frame with a predictable resolution pattern given proper management. We therefore propose detailed guidelines for management of major immune-related adverse events that are anticipated with antiprogrammed death-1/programmed death-ligand 1 therapies based on general experience with other monoclonal antibodies and the established management algorithms for immune-related adverse events for cytotoxic T-lymphocyte antigen-4 blockade with ipilimumab. We anticipate that the antiprogrammed death-1 strategy will become a viable and crucial clinical strategy for cancer therapy.

The toxicities of newer targeted therapies are different from those seen with the traditional chemotherapy. Mammalian target of rapamycin (mTOR) inhibitors are evolving into an important class of drugs in oncology, and this class of drugs presents with a variety of different toxicities. Although similar to the toxicities seen in transplantation, these rapamycin analogs have unique side effects when compared to traditional chemotherapy agents. While most of the toxicities are mild, few can be severe and require routine monitoring. Mucositis and rash are the most common side effects. The metabolic toxicities, hyperglycemia, hyperlipidemia, and hypophosphatemia are different from the side effects traditionally seen with chemotherapy. This review will focus on the common toxicities seen with the mTOR inhibitors.

BACKGROUND: Assessing the role of the pharmacist in an outpatient oncology clinic requires quantification of parameters that are important to the patient and the healthcare system. Patient evaluations not only serve as benchmarks for a process; but may also predict behavior such as utilization of care, continuity with the provider, and compliance. PURPOSE: To identify the role of the patient-pharmacist relationship and enhance patient satisfaction with care, a survey tool was developed and utilized. METHODS: A 20-item, 2-page survey tool was developed and administered to oncology patients actively receiving treatment at the Cancer Therapy & Research Center (CTRC) in San Antonio, Texas. Following approval from the Investigational Review Board, survey distribution began on December 1, 2009 and continued through February 2010. Basic social and demographic data were collected. Satisfaction with pharmacy service was assessed with questions on a Likert ranking scale detailing time spent with pharmacists, knowledge of medication therapy, willingness to pay for clinical pharmacy services, etc. The primary outcome was the impact of the pharmacist-patient relationship assessed by examining the interaction between time spent with pharmacist, understanding of medications, and desire for future pharmacy counseling services. RESULTS: A total of 77 surveys were administered and collected. Of the patients surveyed, 86% stated that it is important for patients to discuss their treatment with a pharmacist and 76% requested pharmacy follow-up at future visits. CONCLUSION: This cross-sectional survey reveals that patients are interested in visiting with a pharmacist regularly during chemotherapy treatment and patients may be willing to pay for pharmacy counseling services.

BACKGROUND: Nausea and vomiting is one of the most feared side effects of chemotherapy; however, in the past 20 years, a better understanding of the pathophysiology of chemotherapy-induced nausea and vomiting (CINV) has led to the introduction of newer antiemetics, which have improved the management of this side effect. OBJECTIVE: This article reviews the prevention of CINV and the role of aprepitant, the first of the newest class of antiemetics, the neurokinin-1 inhibitors. A brief description of the pathophysiology of CINV and the background on the prevention of CINV using the 5-HT(3) antagonists is outlined. The pharmacology, pharmacokinetics, drug interactions and various clinical studies with aprepitant are reviewed. METHODS: The literature about aprepitant is reviewed focusing on the role of aprepitant in the management of CINV in relationship to other commonly used antiemetics. The literature was searched regarding aprepitant and its pharmacological characteristics, pharmacokinetics, drug interactions and various clinical studies. CONCLUSION: Aprepitant has a significant role in the management of CINV, as it allows the majority of patients to complete their chemotherapies without significant morbidity. Its use in a variety of clinical settings in cancer patients needs to be further explored.
