Consultations pharmaceutiques en oncologie : mise en place, bilan à un an et perspectives

[Implementation of pharmaceutical consultations in digestive oncology in a teaching hospital: one-year outcomes]

INTRODUCTION

The announcement of a cancer diagnosis is traumatic for the patient. In France, an announcement system has been in place, providing medical time for announcement and treatment proposal, nursing time for support, without including the pharmacist. In order to improve management of patients treated with intravenous anticancer drugs, we set up introductory pharmaceutical consultations in digestive oncology. The aims were to assess the situation one year after the introduction of these consultations, and to assess their contribution.

METHODS

When a patient was diagnosed with digestive cancer and receiving intravenous treatment, a pharmaceutical initiation consultation was scheduled. Indicators of activity (number of consultations, average duration, average preparation time and various delays) and results (number and type of pharmaceutical interventions, patient satisfaction) were collected in order to assess activity.

RESULTS

Forty-seven pharmaceutical initiation consultations were carried out. The average duration of the consultations was 39.3minutes. Consultations were carried out on average 12.1 days after the medical consultation and 9.6 days before the first chemotherapy treatment. Twenty-nine patients responded to the satisfaction questionnaire. All were satisfied, and the majority of patients said they had improved their knowledge of cancer treatment.

DISCUSSION

This activity enables us to review with patients essential aspects of their care, such as implanting an implantable chamber catheter, anti-cancer treatment and managing potential side effects and improve their self-care skills.

Practicing and evaluating clinical pharmacy in oncology: Where are we now? A scoping review

BACKGROUND

Clinical pharmacy is a discipline structured around multiple activities whose objective is to secure patient care. Among all the specialties where it can be applied, oncology is a field of choice. More and more studies are being conducted on the impact of this activity, but their methodology and results seem at first sight very heterogeneous.

OBJECTIVE(S)

The objective of this literature review was to describe the clinical oncology pharmacy activities found in the literature, and analyze the methodology used and the outcomes measured by the authors for their evaluation.

METHODS

This literature review was based on the PRISMA-ScR criteria. The Embase, CINAHL, Google Scholar, and PsycINFO databases were searched. All studies reporting the evaluation of hospital-based clinical pharmacy activity in cancer patients were included based on a previously validated search equation. The search was conducted until the end of 2020. The quality of all studies was assessed using the MMAT.

RESULTS

Of the 2521 results of the initial query, 93 were selected for complete review. The main interventions implemented were pharmaceutical analysis as well as pharmaceutical interviews. The indicators assessed most often were the number of pharmaceutical interventions as well as treatment-related problems. The overall quality assessment score was 55%.

CONCLUSION

Clinical pharmacy activity in oncology still lacks robust studies, whether methodologically or of the measured indicator. Patient-centered impact indicators are still too rare. This area of research should focus on the homogenization of indicators and their relevance.

Adverse events of targeted therapies approved for women's cancers

Breast cancer and gynecologic cancers affect >3 million women worldwide each year. With advances in precision medicine, a growing number of targeted therapies have been approved recently, and new therapeutic classes have emerged, including cell cycle inhibitors for hormone receptor positive breast cancer, antibody drug conjugate for human epidermal growth factor receptor 2 positive and triple negative breast cancer, and poly-ADP-ribose polymerase inhibitors for ovarian cancer. This article focuses first on the challenges for health care systems to address the specificities of each emerging targeted therapy and new issues raised by oral antitumor treatments, including individualization of prescriptions, drug–drug interaction assessment, pharmaceutical counseling, patient education, and outpatient management. Then, we provide an overview of the main adverse effects of targeted therapies approved for breast and gynecologic cancers, such as hematologic toxicity of cyclin-dependent kinase 4/6 inhibitors and poly-ADP-ribose polymerase inhibitors, metabolic disorders of phosphatidylinositol-3-kinase/Akt/mammalian target of rapamycin inhibitors, and cardiovascular toxicity of agents targeting human epidermal growth factor receptor 2.

Influence of the implementation of a multidisciplinary consultation program on adherence to the first ever course of oral antineoplastic treatment in patients with cancer

PURPOSE

To evaluate adherence (as measured by the medication possession ratio) to the first ever course of oral antineoplasic treatment in cancer patients before and after the implementation of a multidisciplinary consultation program (involving an oncologist, a pharmacist, and a nurse) and to investigate the program's impact on adverse events and drug-related problems.

PATIENTS AND METHODS

In a retrospective single-center study, we compared the medication possession ratio 2 months after treatment initiation in a control group (before multidisciplinary consultation program implementation) versus an interventional group (after multidisciplinary consultation program implementation).

RESULTS

Two months after oral antineoplasic treatment initiation, the mean ± standard deviation medication possession ratio did not differ significantly when comparing the interventional (multidisciplinary consultation program) group (n = 33; 0.99 ± 0.06) with the control group (n = 64; 0.94 ± 0.16) (p = 0.062). Patients in the multidisciplinary consultation program group had fewer adverse events in general (41, vs 109 in the control group; p = 0.048) and digestive adverse events in particular (6 vs 29, respectively; p = 0.007). A total of 53 and 40 drug-related problems were identified in the control and multidisciplinary consultation program groups, respectively (p = 0.074).

CONCLUSIONS

Implementation of an multidisciplinary consultation program was not associated with a significant difference in drug adherence (as assessed by the medication possession ratio), which was good before and after implementation. The multidisciplinary consultation program was associated with a lower incidence of adverse events.

Real-life drug-drug and herb-drug interactions in outpatients taking oral anticancer drugs: comparison with databases

PURPOSE

Due to polypharmacy and the rising popularity of complementary and alternative medicines (CAM), oncology patients are particularly at risk of drug-drug interactions (DDI) or herb-drug interactions (HDI). The aims of this study were to assess DDI and HDI in outpatients taking oral anticancer drug.

METHOD

All prescribed and non-prescribed medications, including CAM, were prospectively collected by hospital pharmacists during a structured interview with the patient. DDI and HDI were analyzed using four interaction software programs: Thériaque^®, Drugs.com^®, Hédrine, and Memorial Sloan Kettering Cancer Center (MSKCC) database. All detected interactions were characterized by severity, risk and action mechanism. The need for pharmaceutical intervention to modify drug use was determined on a case-by-case basis.

RESULTS

294 patients were included, with a mean age of 67 years [55-79]. The median number of chronic drugs per patient was 8 [1-29] and 55% of patients used at least one CAM. At least 1 interaction was found for 267 patients (90.8%): 263 (89.4%) with DDI, 68 (23.1%) with HDI, and 64 (21.7%) with both DDI and HDI. Only 13% of the DDI were found in Thériaque^® and Drugs.com^® databases, and 125 (2.5%) were reported with similar level of risk on both databases. 104 HDI were identified with only 9.5% of the interactions found in both databases. 103 pharmaceutical interventions were performed, involving 61 patients (20.7%).

CONCLUSION

Potentially clinically relevant drug interaction were frequently identified in this study, showing that several databases and structured screening are required to detect more interactions and optimize medication safety.

Pharmaceutical consultation to detect drug interactions in patients treated with oral chemotherapies: A descriptive cross-sectional study

OBJECTIVE

The development of oral chemotherapy (OC) has led to the recent establishment of multidisciplinary programmes involving pharmacists. We evaluated the utility of our local programme for detecting potential interactions with OCs, particularly drug-drug interactions (DDIs) and herbal-drug interactions (HDIs).

METHODS

We performed a single-centre retrospective descriptive study of patients on OC attending a pharmaceutical consultation (PC) during a seven-month period. These consultations included the use of various complementary tools/databases to search for interactions.

RESULTS

We analysed 308 treatments taken by 42 consecutive patients. Fifty-four potential interactions with OCs were detected in 26% (n = 79) of the treatments taken by patients: 46 DDIs (32 minor, 12 major, 2 contraindicated) and eight HDIs. Five interventions associated with interactions were suggested by pharmacists during the consultations (4 were taken into account by oncologists). The total mean time spent on each PC for an individual patient was 80 minutes (36 minutes of preparation, 44 minutes with the patient).

CONCLUSION

This pilot study highlights the importance of studying interactions in such patients, and of the expertise of pharmacists for detecting interactions, which were found in more than one in four treatment lines. The further development of such activities, which already take up considerable amounts of time, is therefore warranted.

[Optimising drug dispensation by pharmacy technicians: A quality approach]

INTRODUCTION

In a context of continuity of quality improvement, we are committed to enhancing the care management and medication management of outpatients in the drug dispensation unit of our pharmacy. An audit was carried out to assess the training needs of pharmacy technicians (PTs).

MATERIALS AND METHODS

All drug dispensations done over a 9-week period by the units PTs were audited. Data collected were: PTs' presentation to the patient, duration of drug dispensation, notion of introduction or renewal, the tools used during retrocession, and the explanations given to the patient about her/his treatment. PT perceptions and patient satisfaction were evaluated on a Likert scale from 1 to 5 and on a scale from 1 to 4, respectively.

RESULTS

One hundred drug dispensation were audited: 21 introductions and 79 renewals. Tools were used in 52% of introductions and 11% of renewals. Administration modalities were explained for all introductions but for only 57% of renewals, 47% of adverse events and 9.5% of storage methods. Tolerance was discussed in 34% of drug dispensations and compliance in 19%. The scores of PT perception and patient satisfaction were 4.4/5 and between 3/4 and 3.9/4 depending on the items, respectively.

CONCLUSION

Several areas for improvement are highlighted in this survey. PTs' complementary should include communication with outpatients. This approach is an integral part of the ISO 9001 certification obtained in 2019 in our drug dispensation unit.

[Optimization of the "pharmaceutical consultation" practiced by pharmacists - Review, feedback and future proposals for development since the introduction of the initiative in 2013 focusing on the Calvados area]

In 2012, a National Agreement of Pharmacists was initiated in France and then amended in 2013 to introduce the "Pharmaceutical consultation". These consultations must be conducted by the pharmacist with the patient in a confidential area in pharmacy or patient residence. The objective is to decrease the frequency of negative side effects of the medical treatments (anti-vitamins k, direct oral anticoagulants and inhaled corticoid) and to improve the correct use of medication therefore assure the safety of the patient. This initiative also recognizes the expertise of the pharmacists who are remunerated with 50 euros per year and per patient from Social Security. This publication is based on a survey conducted in the whole Calvados area and it is based on several individual interviews. It gives a clear picture about how effective the practice has been so far. It shows that the "Pharmaceutical consultation" is currently only proposed to patients by 40% of pharmacists in this area, additionally the practice decreased by 85% in the pharmacies since 2013. However, 8 on 10 pharmacists recognized a real benefit for patients who subscribed for consultation. Independently, the number of non-subsidized conversation initiatives carried out by pharmacists (anti-tobacco, pregnancy, diabetes) are increasing. This finding leads to the investigation of the causes for not practicing the "Pharmaceutical consultation". The causes for not carrying out the consultations were identified, quantified, analysed and classified with a view to proposing short, medium and long time actions to optimize the "Pharmaceutical consultation" in a financially feasible manner. Nine practical proposals were identified and groups in three areas of improvement: communication, remuneration and organization.
