Exploring Nursing Adherence Programs for Oral Oncolytics

Specialty pharmacies are becoming more involved in programs that focus on the management of oral oncolytics. The role of health care workers, including pharmacists, physicians, and nurses, is being defined as this therapeutic class grows.

While the escalating number of oral oncolytics offers many cancer patients more convenient and less invasive treatment options compared with infused therapy, oral drugs also demand a new model for patient education, monitoring, and support. This trend is driven by a rising number of novel oral oncology agents in the marketplace, a robust pipeline, and increasing expanded indications for already approved therapies. The health care world has witnessed a remarkable paradigm shift from acute, limited treatment to maintenance therapies and an eventual chronic care model requiring advanced, ongoing care.

With infused oncology regimens, physicians and their nurses interact with patients more often, increasing the ease of monitoring. But with oral oncolytics, providers may often see patients less frequently, only for follow-up appointments. Many patients reason that because the medications are taken by mouth, they lack significant adverse effects. In reality, many oral oncolytics have toxicities as bad as or worse than their infused counterparts.

For these reasons, management programs that focus specifically on the oral oncolytics are becoming more common across the industry, and many managed care organizations are implementing protocols to manage this therapeutic class. Payers are asking specialty pharmacies to support their patients in at least 3 areas:

• Maximize adherence to therapy
• Educate patients about medication tolerance and adverse effects
• Actively monitor regimen adherence, persistency, and length of therapy

"IDEAL" ORAL ONCOLOGY PATIENTS

Ideal candidates for oral oncolytics possess good communications skills (or have responsible, committed family members to communicate on their behalf) and a demonstrated willingness, ability, and discipline to adhere to the medication regimen and recommendations made by their extended health care team, including clinical pharmacy staff. Additionally, patients should be assessed with regard to their:

• Understanding of the importance of their therapy to their disease outcomes
• Potential for adverse effects and agreement to minimization strategies
• Ability to integrate their therapy into their daily routine
• Ability to swallow pills and/or liquids

NURSING TEAMS

Equally essential are additional levels of cooperation and integration among physicians, pharmacists, and other health care providers responsible for patients’ overall care. Role allocation should seek to minimize costs while maximizing job capabilities and skill sets. The challenges surrounding oral oncolytics present unique opportunities for nursing teams to promote and facilitate medication adherence. As integral members of the health care team, nurses are renowned for their patient advocacy, teaching skills, and high-touch care. These qualities can be optimized in the specialty pharmacy setting through a variety of strategies targeting education, communication, and technology (Figure 1).

Goals of patient and/or caregiver consultations are the provision of individualized training and verification of the ability to implement drug and non-drug recommendations. Effective medication education incorporates the pill description, prescribed dosage, storage, disposal, safe handling, and other precautions. Administration and scheduling instructions, such as food requirements, treatment cycles, missed dose protocols, and concomitant therapies, have a high impact potential for the nursing team. Trained oncology nurses can also assist patients in developing realistic expectations, particularly the anticipation of adverse effects, monitoring requirements, and potential dosage changes or treatment interruptions.^1,3

Nursing contributions to adverse effect identification, prevention, and management are essential. With fewer office visits for monitoring, oral oncology patients may be hesitant to report adverse effects, believing that a dose decrease or treatment interruption could compromise efficacy.^2,4 Nurses can reinforce minimization strategies and advise patients when and how to contact their providers or seek emergency care.3 In addition, when an adverse event is identified nurses will obtain details of the event and report back to the physician as well as complete the required FDA MedWatch form which tracks reported events.

PROACTIVE PATIENT CONTACT

While many specialty pharmacies have protocols in place to monitor adherence, an often overlooked topic is patient understanding of the importance of adherence. In a self-reported survey, 33% of breast cancer patients reported that their health care provider discussed the importance of taking their oral oncolytics as directed only once. When asked to select factors that could have increased their adherence, 89% of patients selected knowledge that it might improve clinical outcomes and 60% cited improved side effect management. ⁵ In a survey of 42 comprehensive United States cancer centers, 9 lacked standardized processes to evaluate adherence at office visits.⁶

Scheduled proactive contact can help fill this void, allowing nurses to establish therapeutic relationships, provide ongoing adherence messaging, and encourage disclosure of treatment difficulties.^1,4 Interventions can be designed to coincide with the medication’s adverse effect profile and at other time points when patients may be more likely to discontinue therapy. If the peak incidence of rash is during treatment week 3, a nursing call 10 to 14 days after patients start therapy would be more valuable than a discussion at the first refill. Drug rescue calls, in which nurses seek to identify and resolve reasons for treatment discontinuation, can minimize drug abandonment and increase persistency. During regularly scheduled follow-up calls, nurses can also collect accurate health and medication histories, including prescription, over-the-counter (OTC), and herbal products. These calls provide an opportunity to verbally assess adherence and treatment response, and collect other valuable outcome measures for pharmaceutical hubs, managed markets clients, and prescribing offices.

Should nurses identify barriers beyond their scope or program protocols, such as drug interactions or inappropriate weight-based dosing, patients can be triaged to pharmacists for resolution. Direct nurse-to-prescriber communication, such as notifications regarding adverse effects, nonadherence, disease status changes, and interventions completed, is essential for continuity of care. Potential additional roles for the nursing team include improving medication access through patient assistance programs or non-profit funding organizations and promoting enrollment into manufacturer support programs, which often provide an abundance of clinical resources and support services. Aside from manufacturer-provided materials, nurses can author newsletters and easyto- understand patient guides which serve to reinforce and provide additional education.⁴

As an illustrative example, Diplomat Specialty Pharmacy determines the timing and frequency of patient assessments based on the oral oncolytic's adverse effect profile. A "yes" response to questions, such as those regarding episodes of nausea, vomiting, or diarrhea, triggers an additional series of questions that follow a drug-specific algorithm to determine severity, management, and next steps for triage and prescriber communication. Diplomat also distributes Oncology Care Kits exclusive to each medication with drug and non-drug adverse effect management techniques and OTC samples such as antidiarrheals or stool softeners. Nursing interventions are also timed in accordance with oncology cycles to ensure patient understanding and compliance with scheduled treatment breaks and phasic dosing.

Nursing team efficiency can be increased through a variety of technological innovations. Many specialty pharmacies calculate adherence based on refill dates to augment patient selfreport. Mobile and web technology is increasingly utilized for select patient contact points, surveys, and reminders. Nurses can facilitate participation in electronic medication monitoring programs and reminder packaging services.2 Diplomat examples include Oncology Medication CarePaks printed with the day, time, and week (Figure 2) and nurse calls to enroll patients in GlowCaps pilot programs, featuring electronic visual and audio medication reminders and progress reports of medication-taking events reviewed by the nursing staff.

BARRIERS TO SUCCESS

Several barriers prevent the widespread implementation of successful nursing programs. Limited data has been published demonstrating the effectiveness of specialty pharmacy nursing interventions aimed to promote adherence. Strategies are often developed as initiatives to support manufacturer or managed markets clients and lack a scientific approach with a comparator group and research-driven protocol. This, coupled with insufficient data capture and reporting capabilities, makes it difficult for many to measure program impact. Intervention scheduling may become complex due to treatment interruptions and the need to collect true treatment initiation and restart dates. Patients are opted out of the program for a variety of reasons. Those reasons include regulatory limitations based on state mandates, off-label medication use, hospitalization, and patient choice based on quality of life concerns or disease progression. Some opt-out patients could receive nursing calls before they opt out, which makes data analysis between the 2 groups challenging.

A lack of validated tools, inaccurate recall, and the potential for distortion hinder patient self-reported adherence assessments. Adherence calculations using refill data vary among pharmacies, do not equate to medication ingestion, and cannot account for treatment interruptions or filling prescriptions elsewhere. Cycled oncology therapy may lead to inaccurate calculations and for some the expected duration of therapy due to life expectancy is simply too short for useful results.

Specialty pharmacy’s core values focus on patients, their families, and coordination of care among health care providers. Patient adherence is a key factor to optimize therapeutic outcomes, particularly in oncology, where increasing responsibility now falls to the patient. As the oncology landscape continues to evolve, the specialty pharmacy team must work together with a patientcentric vision to optimize patients’ therapeutic experience and clinical outcomes. The skill set of a nursing team is an invaluable asset in such a program— and its ability to impact adherence and other outcome measures is an area for further exploration.
