Deprescribing

Benzodiazepines or related drug (BZDR) are consumed for hypnotic or anxiolytic purposes in most cases. The consequences of BZDR are multiple with an increased risk of daytime sedation, balance disorders leading to falls and fractures, cognitive disorders, road accidents and dementia. Given their comorbidities, physiological changes, and multiple medications, the elderly are more at risk of suffering from BZDR adverse events. Interprofessional collaboration has shown efficacy in improving prescribing appropriateness and may affect patients outcomes positively. Morever, motivational interviews (MI) may reduce the extent of substance abuse compared to no intervention.

Polymedication in palliative oncology care is a real public health problem. This phenomenon has been shown to increase the risk of iatrogenesis, reduce patients' quality of life and increase healthcare costs. For many years, health policies have been developed in geriatrics to reduce polymedication through deprescription tools. Recently, palliative care initiatives have been introduced, but without having studied the potential specificities of this population (younger, with a different care dynamic and life trajectory). It is important to better understand this population's perceptions of deprescribing in order to adapt tools/actions to make these approaches more efficient. The primary aim of this study is to investigate patients' perceptions of deprescribing in palliative cancer care, and the secondary aim is to investigate factors that may influence patients' attitudes and beliefs about deprescribing. At the same time, we will study the psychometric properties of the rPATD (Revised Patients' Attitudes Towards Deprescribing) in this population (a standardized questionnaire validated in geriatric medicine to assess patients' perceptions of deprescription).An ancillary study will be carried out to investigate the link between patients' health literacy and their perception of deprescribing (health literacy is defined as the ability to acquire, understand and use information in ways that promote and maintain good health). To meet our objectives, we will conduct a 3-year national, prospective, observational, multicenter study with an exploratory sequential mixed design. The study will comprise an initial qualitative phase. Semi-directed individual interviews using a descriptive approach will be carried out (around 25 patients, over an 8-month period). Following analysis of the qualitative data, we will then carry out a quantitative study to determine the distribution of the different profiles within this population and the factors influencing the perception of deprescription. The self-administered questionnaires, rPATD and BMQ (medication beliefs questionnaire), potentially supplemented by other items following analysis of the qualitative data, will be administered to 300 patients (over a 12-month period).The ancillary study will be carried out during this second phase, using a validated self-questionnaire to assess patients' level of literacy. Thanks to the different results, we will improve our knowledge of the perception of deprescription in palliative oncology care, in order to develop approaches adapted to the specificities of our population to reduce polymedication and thus improve the quality of life of our patients and reduce the risks of iatrogenia.

In Belgium, many adults who have suffered from depression keep using antidepressants on a daily basis for years afterwards, sometimes longer than guidelines recommend. Yet for some people who have been feeling well for a long time, this is no longer necessary, while the continued use of antidepressants can lead to side effects and causes additional costs for the healthcare system. However, reducing the doses of antidepressants or stopping altogether is not always easy. Some patients are afraid that their depression will return, and GPs and pharmacists often find the subject difficult to broach. This is why the GPS-AD study is investigating a new approach in which GPs and pharmacists work more closely together to provide better support to patients. First, the GP invites patients who have been taking antidepressants for a long time for a consultation. Together, they discuss whether tapering of the medication is reasonable and feasible. If they agree to stop the treatment, the GP draws up a tapering plan tailored to the patient. The pharmacist helps monitor this process, offering advice and support to the patient while the doses are gradually reduced. The study will extend over a period of two years and will take place in GP practices throughout Belgium. The new approach based on closer collaboration between GPs and pharmacists will be compared to the current standard of care, to determine whether it helps more long-term users to stop taking antidepressants without experiencing a recurrence of depressive symptoms. The name of the study, GPS-AD (General Practitioner and Pharmacist Support for Antidepressant Discontinuation), refers to the collaboration between GPs and pharmacists in tapering of antidepressants, and also symbolises the support and guidance (the 'GPS') provided to patients and healthcare providers in assessing whether long-term use of antidepressants is still necessary.

The goal of this study is to determine if a pharmacist-led educational intervention can reduce the inappropriate use of proton pump inhibitors (PPIs) among adult patients (≥18 years) with potentially inappropriate PPI prescriptions in Ras Al Khaimah. The main questions it aims to answer are: * Can a pharmacist-led education program reduce unnecessary PPI use? * Does the intervention improve patients' quality of life and reduce healthcare costs? Researchers will compare the intervention group (receiving pharmacist-led education and materials) to the usual care group to see if the intervention reduces PPI use and improves patient outcomes. Participants will: * Receive educational materials from pharmacists, including a patient educational brochure, PPI patient decision aid, PPI deprescribing pamphlet, and PPI patient action plan. * Physicians involved will also receive a pharmaceutical intervention, which includes a physician educational brochure, PPI evidence-based deprescribing guideline, PPI deprescribing algorithm, and whiteboard videos on PPI deprescribing. * Patients will be followed up for 6 months to monitor changes in PPI use, symptoms, and quality of life.
