Adherence and Patients' Experiences with the Use of Capecitabine in Daily Practice

Adherence to oral anti-cancer therapies in older patients is similar to that of younger patients

Introduction

The use of oral anti-cancer therapies is becoming increasingly common in the management of cancers, raising the question of adherence. The objective of this study was to assess adherence to oral anti-cancer therapies, as well as the impact of various factors that may influence it.

Methods

Patients starting oral chemotherapy (tyrosine kinase inhibitor or cytotoxic) were followed up for 3 months using a medication diary, which was given to the patient by the pharmacist during a multidisciplinary consultation. Adherence was assessed using the diary, as well as by counting the tablets they brought back.

Results

One hundred and fifty patients were included in the study. The main oral chemotherapy agents prescribed were palbociclib (23.3%), everolimus (18.7%), and capecitabine (13.3%). The adherence at the end of the 3 months, by means of dose intensity (i.e. percent of the dose prescribed that has been taken), was 95.5%. No significant difference in adherence was found based on age, sex, family circumstances, health status, co-medication, type of oral therapy, tumor location, number of previous treatment lines, or presence of toxicity. The main reasons for non-adherence were forgetting (50%) and toxicity (21%). Fifty-seven patients prematurely discontinued the study: 40.3% for toxicity and 36.8% for disease progression.

Conclusion

Adherence in this study is high in comparison to literature, which can be explained by close multidisciplinary follow-up. Moreover, no significant difference was observed between younger and older patients.

Real-world outcomes for neoadjuvant capecitabine versus infusional 5-fluorouracil in the treatment of locally advanced rectal cancer

BACKGROUND

Neoadjuvant chemoradiation therapy is standard-of-care treatment for locally advanced rectal cancer (LARC). A pathological complete response (pCR) following chemoradiation therapy is an early indicator of treatment benefit and associated with excellent survival outcomes, with capecitabine largely replacing infusional 5-fluorouracil as the choice in routine care of LARC.

AIMS

To analyse the uptake of capecitabine usage over time, and on the back of clinical trial data demonstrating equivalence between fluoropyrimidines, confirm that efficacy is maintained in the real-world setting.

METHODS

We analysed data from a prospectively maintained colorectal cancer database at three Australian hospitals including patients diagnosed from January 2009 to December 2018. Pathological response was determined as either complete or incomplete and compared for patients receiving 5-FU or capecitabine.

RESULTS

A total of 657 patients was analysed, 498 receiving infusional 5-FU and 159 capecitabine. Capecitabine use has markedly increased from approval in 2014 in Australia, now being used in more than 80% of patients. Patient characteristics were similar by treatment, including age, tumour location and pre-treatment stage. pCR was reported in 22/159 (13.8%) of capecitabine-treated patients and 118/380 (23.7%) that received 5-FU (P ≤ 0.01). More capecitabine-treated patients received post-operative oxaliplatin (44.2% vs 6.3%, P < 0.01). Two-year progression-free survival was similar (84.9% vs 88.0%, P = 0.34).

CONCLUSIONS

Capecitabine is now the dominantly used neoadjuvant chemotherapy in LARC. Capecitabine use was associated with a lower rate of pCR versus infusional 5-FU, a difference not explained by examined patient or tumour characteristics. Poor treatment compliance with oral therapy in the real-world setting is one possible explanation.

Adherence to oral anticancer chemotherapies and estimation of the economic burden associated with unused medicines

Background The list of oral and expensive chemotherapy agents has lengthened over the last few years and has created unique medication adherence concerns. In a real-life setting, patients often do not take their medications as prescribed. This pattern is associated with poor outcomes and increased health care costs. Objectives To estimate the adherence to oral anticancer chemotherapies and to determine the economic burden of unused medicines due to patients' death. Setting Alsace (France). Method This retrospective study was carried out by using ERASME, an Insurance Healthcare database. Main outcome measures Adherence was calculated using medication possession ratio and economic impact using prescription refill data. Results 10,734 patients were treated with oral anticancer medicines (cytotoxic agents, hormonal and targeted therapies). Averaged adherence of 0.86 was observed although it varied significantly between subclasses (cytotoxic agents: 0.69 ± 0.14, hormonal therapy: 0.91 ± 0.17 and targeted therapy: 0.79 ± 0.17). 1631 patients died during the study period. The expenses related to unused chemotherapies amounted to €152,175. Conclusions Our data showed that overall adherence to oral anticancer medicines was above the acceptable limit of adherence of 80% with a marked graduation in values between cytotoxic agents, hormonal and targeted therapies. These statistical significant differences in medication possession ratio could be related to the intrinsic toxicity of the three subclasses of molecules, their tolerance and adverse effects. To limit the cost associated with unused medicines, interventions such as dispensing expensive oral anticancer chemotherapies per unit over shorter periods and not only on monthly intervals could be implement.

Patient-Oncologist Communication Regarding Oral Chemotherapy During Routine Office Visits

PURPOSE

Although studies in other clinical areas have shown that patient-clinician communication can positively influence adherence to medications, little is known about how oncologists address medication counseling during routine office visits. We describe patient-oncologist office-based discussions of oral chemotherapy treatment.

METHODS

Transcripts of 24 patient-oncologist office visits were obtained from a national database. Patients were aged ≥ 19 years and prescribed capecitabine for colorectal cancer. We developed a structured coding worksheet using medication-counseling concepts previously identified as important to medication adherence and a grounded approach. Two coders reviewed transcripts for oncologists' provision of medication information, assessment of patients' adherence to medication, and the provision of self-management support for management of adverse effects. We assessed interrater reliability with Cohen κ statistics. We describe the counseling concepts present within patient-oncologist conversations and present illustrative quotes to describe how they were discussed.

RESULTS

Oncologists generally provided patients who had yet to initiate therapy comprehensive medication information; those in the midst of treatment received less information. Oncologists discussed patients' continued use of the medication (or discontinuation) among all patients who had initiated therapy (N = 18). How the patient was taking the medication (ie, therapy implementation) was less commonly discussed. Medication adverse effects were also discussed in all encounters. Self-management strategies were commonly provided, albeit mostly in response to a presenting symptom and not preemptively. Patients' use of concurrent medications, financial access to therapy, and assessments of logistical arrangements were discussed more sporadically.

CONCLUSION

Using audio recordings from a national sample of patient-oncologist office visits, we identified several potentially important opportunities to enhance medication counseling among patients prescribed capecitabine for the treatment of colorectal cancer.

Patients' lived experiences with antineoplastic medicines for the management of malignant solid tumours: A systematic review

BACKGROUND

Antineoplastic medicines affect the patients' physical and psychosocial well-being posing challenges for patients, caregivers and healthcare professionals. However, little is known about the patients' lived experience with medicines (PLEM) for antineoplastic treatment. It is the lived experience that gives meaning to each individual's perception of a particular phenomenon which is influenced by internal and external factors relevant to the individual.

OBJECTIVES

To critically appraise, synthesise and present the available evidence of patients' lived experience with antineoplastic medicines prescribed for the management of malignant solid tumours.

METHOD

A systematic literature search was conducted in six electronic databases for articles published in English with no date restrictions. The search terms were related to beliefs, practice and burden in relation to patient, antineoplastic medicines, tumours and lived experience. Study selection, quality assessment and data extraction were performed independently by 2 reviewers. Research findings were analysed using narrative and meta-synthesis approaches.

RESULTS

The search retrieved 31,004 articles with only 10 studies satisfying the inclusion and exclusion criteria. These studies were published between 2005 and 2016 in Europe (n = 6), America (n = 3) and Asia (n = 1). Nine themes were identified to contribute to the patients' lived experience with antineoplastic medicines. These were (a) influence from family members, healthcare professionals, media and culture, (b) general attitude towards medicine, (c) accepting medicine, (d) modifying or altering medicine regimen or dose, (e) medicine characteristics, (f) medicine routine, (g) medicine adverse events, (h) medicine and social burden and (i) healthcare associated medicine burden. Patients tend to undergo a continuous process of reinterpretations of their experience with medicines throughout their treatment journey.

CONCLUSION

The use of antineoplastic medicines has a profound effect on the patients' lives. Further longitudinal in-depth studies are required to provide deeper insight into PLEM and support patients in their treatment journey.

2018 Hematology/Oncology Pharmacist Association Best Practices for the Management of Oral Oncolytic Therapy: Pharmacy Practice Standard

PURPOSE:

The aim of the current work was to present a pharmacy practice standard from the Hematology/Oncology Pharmacy Association (HOPA) on the management of oral oncolytic therapy.

METHODS:

The HOPA Standards Committee organized a work group of oncology pharmacist specialists to create a pharmacy practice standard for the management of oral oncolytic therapy that describes the pharmacist’s role on the cancer care team, provides examples of practice tools and resources, summarizes current data related to outcomes, and discusses opportunities to enhance the care of patients with cancer who receive oral oncolytic therapy. We reviewed primary literature, including currently published oral oncolytic guidelines and HOPA’s Scope of Hematology/Oncology Pharmacy Practice.

RESULTS:

Management of oral oncolytic therapy was divided into the following primary areas: prescribing, education, dispensing and distribution, and monitoring and follow-up. Pharmacists’ roles were summarized in each area with a focus on interprofessional collaboration, communication, patient safety, and quality of patient care. Standards describe the best practices in each area (Table 1).

CONCLUSION:

Multiple opportunities exist for pharmacists to enhance the care of patients with cancer who receive oral oncolytics through collaboration with oncology care team members. The role of the oncology pharmacist in the care of this patient population is critical given the complexities related to cost, tolerability, and safety of oral oncolytic medications; issues of access; and the monitoring and follow-up of patients receiving this therapy.

The association between patients' perceived continuity of care and beliefs about oral anticancer treatment

PURPOSE

To explore factors associated with necessity beliefs and concerns among patients receiving oral anticancer therapy (OACT) and, specifically, to examine the relationship between continuity of care (COC) and patients' beliefs about OACT.

METHODS

A cross-sectional study was conducted among patients from four oncology centers receiving OACT (either targeted, hormonal, or chemotherapy). Two months after OACT initiation, patients were asked to participate in a face-to-face or telephone survey. The Beliefs about Medicines Questionnaire was used to examine patients' perceptions of their personal necessity for OACT and concerns about potential adverse effects. The Nijmegen Continuity Questionnaire was used to assess patients' perceived COC. Data on clinical characteristics were collected from medical records.

RESULTS

Participants' beliefs about OACT necessity (n = 91) were found to be associated with COC within the oncology team, and with COC between the oncology specialist and the primary care physicians (β = 0.27, p = 0.003; β = 0.22, p = 0.02, respectively), beyond age, depression, and cancer type (ΔR² = 0.14, p < 0.001). Additionally, the difference between participants' beliefs about OACT necessity and their OACT-related concerns was associated with COC within the oncology team (β = 0.30, p = 0.001), beyond age, income, family status, and cancer type (ΔR² = 0.09, p = 0.001).

CONCLUSIONS

This study shows that cancer patients' perceptions about the COC between care providers are related to their beliefs about OACT necessity, thus providing evidence for the importance of health care delivery approaches that support COC within the oncology team and between the oncology specialist and the primary care physician.

Use and Effects of Patient Access to Medical Records in General Practice Through a Personal Health Record in the Netherlands: Protocol for a Mixed-Methods Study

Background

In the Dutch health care system, general practitioners hold a central position. They store information from all health care providers who are involved with their patients in their electronic health records. Web-based access to the summary record in general practice through a personal health record (PHR) may increase patients’ insight into their medical conditions and help them to be involved in their care.

Objective

We describe the protocol that we will use to investigate the utilization of patients’ digital access to the summary of their medical records in general practice through a PHR and its effects on the involvement of patients in their care.

Methods

We will conduct a multilevel mixed-methods study in which the PHR and Web-based access to the summary record will be offered for 6 months to a random sample of 500 polypharmacy patients, 500 parents of children aged <4 years, and 500 adults who do not belong to the former two groups. At the patient level, a controlled before-after study will be conducted using surveys, and concurrently, qualitative data will be collected from focus group discussions, think-aloud observations, and semistructured interviews. At the general practice staff (GP staff) level, focus group discussions will be conducted at baseline and Q-methodology inquiries at the end of the study period. The primary outcomes at the patient level are barriers and facilitators for using the PHR and summary records and changes in taking an active role in decision making and care management and medication adherence. Outcomes at the GP staff level are attitudes before and opinions after the implementation of the intervention. Patient characteristics and changes in outcomes related to patient involvement during the study period will be compared between the users and nonusers of the intervention using chi-square tests and t tests. A thematic content analysis of the qualitative data will be performed, and the results will be used to interpret quantitative findings.

Results

Enrollment was completed in May 2017 and the possibility to view GP records through the PHR was implemented in December 2017. Data analysis is currently underway and the first results are expected to be submitted for publication in autumn 2019.

Conclusions

We expect that the findings of this study will be useful to health care providers and health care organizations that consider introducing the use of PHR and Web-based access to records and to those who have recently started using these.

Over-adherence to capecitabine: a potential safety issue in breast and colorectal cancer patients

PURPOSE

The aim of the OCTO clinical study was to measure patients' adherence to capecitabine-based treatment.

METHODS

A cohort of ambulatory patients treated with capecitabine monotherapy for either locally advanced or metastatic, breast or colorectal cancer was monitored for 6 cycles. Adherence was assessed in all patients by self-completed questionnaires on disease, pill-count and pharmacological dosage of FBAL (metabolite of capecitabine); and in half of the cohort by electronic medication event monitoring systems (MEMS™) recording the opening times of the device.

RESULTS

Forty patients were enrolled between November 2008 and September 2011 and treated by capecitabine for an average of 4.75 cycles (range 1-6). Hand-foot syndrome (HFS) was the most frequently reported toxicity (35% patients), and to a lesser extent fatigue and/or asthenia (21%), nausea and/or vomiting (13%) and diarrhea (11%). In the MEMS™ cohort, 20 patients were included. Patients' adherence was excellent with very few missing occasions (23/2272 records). Close analysis of MEMS™ data revealed unexpected medication patterns, such as patients taking extra days of medication beyond planned cycle, patients taking extra doses per day and patients missing a day of dosing and "compensating" by taking extra the following day (N = 7, 18%). A trend was found between over-adherence and high-grade toxicity (grades 3 and/or 4): OR 4.74 [0.65-45.2], p = 0.13 and higher AUC (p = 0.16). There was a trend towards increased AUC of FBAL in over-adherent patients (p = 0.16).

CONCLUSION

Adherence to oral anticancer chemotherapy was found excellent in this population suggesting over-adherence to capecitabine and potential safety implications for outpatients' drugs.

Do treatment patterns alter beliefs cancer patients hold regarding oral oncolytic agents?

OBJECTIVE

Cancer patients, particularly those prescribed with oral oncolytic medications, face treatment side effects and temporary and permanent stoppages of treatment. This research examines how events during treatment affect patients' beliefs regarding oral oncolytic medications.

METHODS

A total of 272 cancer patients initiating 1 of 28 oral oncolytic agents were followed for 12 weeks. Assessments of Beliefs About Medications Questionnaire, symptoms, physical function, and depression measures were performed during telephone interviews at intake (medication start) and 4, 8, and 12 weeks. Electronic medical record audits identified dates of temporary and permanent medication stoppages. Linear mixed-effects models were used for longitudinal analyses of the Beliefs About Medications Questionnaire scores in relation to patient characteristics, symptom severity, and medication stoppages.

RESULTS

Over the initial 12 weeks, beliefs about the necessity of oral medications have increased, concerns have decreased, and interference of medications with daily lives has increased. Permanent stoppage of a medication predicted significant declines in beliefs about its necessity over time. Male patients, those less educated, those reporting higher symptom severity, and those experiencing temporary stoppages had greater concerns. Interference of medications with daily life was higher for males, increased with higher symptom severity, and differed by drug category.

CONCLUSIONS

Patients' beliefs in the necessity of their oral medication were affected only by a permanent drug stoppage. Symptom severity, education, and patient sex affected patients' beliefs about their concerns with their medications and the interference medications posed for their daily lives. Interventions may need to target the distinct dimensions of beliefs during treatment with oral oncolytic agents.
