Brief summary

Over the past decade, oral administration of chemotherapy has significantly increased and is anticipated to continue to grow. Despite the conveniences, these oral regimens can be complex and pose challenge to patient adherence. Further safety concerns are warranted due to insufficient patient education, general perception of reduced toxicity with oral treatment, improper prescribing practice, and the lack of monitoring of observable adverse effects. Therefore, effective medication counselling and patient education is vital to empower patients and their caregivers to increase adherence and safely managed medication to achieve optimal treatment outcome. This study aims to evaluate the effectiveness of pharmacist intervention with structured oral chemotherapy education and patient monitoring on capecitabine treatment effectiveness (Relative Dose Intensity (RDI), Adherence and Persistence), safety outcomes (Adverse Event, Drug Related Problem and Health service utilization) and chemotherapy knowledge and self-efficiency among cancer patient care in Penang, a northern state oncology referral centre. There are numerous published studies of pharmaceutical care implementations focusing mainly on in-patient setting and currently evolving in ambulatory cancer patients especially in western countries compared to Asian region. However systematic reviews show major gap still exist with paucity of scientific evidence on the effectiveness of therapeutic educational interventions for improving patient safety and adherence to oral chemotherapy mainly due to study design and method that are unable to strongly prove the outcome. Hence highlighting the novelty and significance for this research using randomized controlled design, standardized & validated tools for multimodal pharmacist intervention, long-term clinical outcome such as RDI with longitudinal assessment till treatment completion.

Interventions

OTHERPharmacist-led Oral Chemo Care Program (POCCP)

Structured intensified pharmaceutical care program for patients ongoing oral chemotherapy treatment. Led by oncology experienced clinical pharmacist and run alongside oncologist patient review at the clinic or daycare. It utilizes structured educational material (for patients) and monitoring guideline or checklists (for pharmacists) during provision of service at each clinic visit such as patient education, pre-treatment review, medication reconciliation, prescription screening (dose, regime, supportive meds), adherence, adverse drug event monitoring and treatment recommendations on basis of agreed protocols. Pharmacist scheduled additional review within 1-week interval of start of oral chemotherapy at clinic or via phone call (according to patient's preference) will also be conducted to review patients taking their oral medications at home, assess adherence and symptom experienced to provide individualized recommendations or support to patients.

Design outcomes

Primary

MeasureTime frameDescription
Relative Dose Intensity - End of Treatment6 monthsRDI will be assessed at the end of Cycle 8 (each cycle is 21 days). Relative dose intensity (RDI), defined as the total dose administered divided by the total dose specified by the corresponding standard regimen.
Relative Dose Intensity - Mid Treatment3 monthsRDI will be assessed at the end of Cycle 4 (each cycle is 21 days). Relative dose intensity (RDI), defined as the total dose administered divided by the total dose specified by the corresponding standard regimen.
Daily Adherence6 monthsDaily Adherence will be assessed at the end of Cycle 8 (each cycle is 21 days). The daily adherence level determined by the pill count, patient diary record at each visit, which considered both the correct administration of capecitabine twice daily for 14 days and correct non-administration of any dose on rest days to be determined as adherent throughout the 21 day cycle.

Secondary

MeasureTime frameDescription
Medication Adherence Report Scale (MARS-5) C13 weeksMARS-5 score will be assessed at the end of Cycle 1 (each cycle is 21 days). Medication Adherence Report Scale (MARS-5) Questionnaire consists of five questions on patterns of nonadherent behaviour to assess patients self-reported adherence to oral capecitabine. Scoring is on a 5-point Likert scale and total score range between 5 and 25 whereby a higher scores means better adherence.
Medication Adherence Report Scale (MARS-5) C43 monthsMARS-5 score will be assessed at the end of Cycle 4 (each cycle is 21 days). Medication Adherence Report Scale (MARS-5) Questionnaire consists of five questions on patterns of nonadherent behaviour to assess patients self-reported adherence to oral capecitabine. Scoring is on a 5-point Likert scale and total score range between 5 and 25 whereby a higher scores means better adherence.
Medication Adherence Report Scale (MARS-5) C86 monthsMARS-5 score will be assessed at the end of Cycle 4 (each cycle is 21 days). Medication Adherence Report Scale (MARS-5) Questionnaire consists of five questions on patterns of nonadherent behaviour to assess patients self-reported adherence to oral capecitabine. Scoring is on a 5-point Likert scale and total score range between 5 and 25 whereby a higher scores means better adherence.
Capecitabine Medication Taking Behavior Questionnaire C13 weeksCapecitabine Medication Taking Behavior (CMTB) will be assessed at the end of Cycle 1 (each cycle is 21 days). The questionnaire consists of four questions to further identify aspects of patients non-adherence, their medication-taking and medication-stopping behavior specific for oral capecitabine. Scoring is on a 5-point Likert scale and total score range between 5 and 20 whereby a higher scores means better adherence.
