Multi-professional development of a competency framework for patients with a Port-a-Cath (PAC).

PURPOSE: In France, 40,000 Port-a-Cath (PAC) are inserted each year. These medical devices are prone to complications during their insertion or use. The education of patients wearing these devices could be a lever to reduce the risk of complications. The objective of this work was to develop, in a multi-professional and consensual manner, a unique and specific skills reference framework for patients with PAC and to propose it as a reference tool for health professionals. METHODS: A multidisciplinary working group was set up to draw up this reference framework of skills. The first stage of the work consisted of a reflection leading to an exhaustive list of competencies necessary for the patient. These skills were then classified according to three different fields of knowledge (theoretical, know-how and attitudes). Finally, the working group identified priority competencies and established a grid that can be used to evaluate the level of acquisition of these competencies. RESULTS: Fifteen competencies were identified: five relating to theoretical knowledge, six relating to know-how and four relating to attitudes. These competencies were broken down into sub-competences. Seven competencies or sub-competencies were selected to constitute the list of priority competencies. DISCUSSION: This competency framework provides a reference framework for the education of patients with PAC and will help to harmonise practices within the different teams that care for patients with PAC.

What about the relevance of PIP of psychotropics in older psychiatric inpatients?

OBJECTIVE: In 2019, a regional survey of potentially inappropriate prescriptions (PIP) of psychotropic drugs in elderly psychiatric inpatients was carried out highlighting their inappropriate use in this population. The aim of this study was to assess the clinical relevance - defined as the provision of an appropriate and necessary treatment, chosen from other alternatives as being the most likely to produce the expected results for a given patient - of these prescriptions considered inappropriate according to current established criteria. MATERIAL AND METHOD: Patients aged over 75, or 64 to 75 and polypathological with at least one PIP of psychotropic drugs or drugs with a high anticholinergic burden, identified by an audit grid established on the basis of STOPP/STARTv2 criteria and the Laroche list on the prescription at 48h of hospitalization, were included. The weighing of the inappropriateness nature of the prescription (resistance to treatment, period of crisis, comorbidities…) was established by a pharmacist-psychiatrist pair on the entire computerized record of the current episode. The clinical relevance of the PIP and the overall prescription was rated as 0 (irrelevant), 1 (partially relevant) or 2 (relevant). RESULTS: Thirty-four patients were included. One hundred and twenty-five PIP of psychotropic drugs were noted: 50.4% concerned benzodiazepines and non-benzodiazepines anxiolytics (BZD/Z), 25.6% neuroleptics (NL), 12% antidepressants (ATD) and 12% drugs with a high anticholinergic burden. On one hand, 49.2% of PIP of BZD/Z, 50% of PIP of NL and 20% of PIP of ATD were considered irrelevant. On the other hand, 49.2% of PIP of BZD/Z, 31.3% of PIP of NL and 13.3% of PIP of ATD were considered partially relevant. Furthermore, 1.6% of PIP of BZD/Z, 18.8% of PIP of NL and 66.7% of PIP of ATD were considered relevant. For PIPs of drugs with a high anticholinergic burden, 80% were deemed irrelevant, 13.3% partially relevant and 6.7% relevant. In all, of the 34 drug prescriptions studied, three (8.8%) were considered irrelevant, 11 (32.4%) partially relevant and 20 (58.8%) clinically relevant. CONCLUSION: This study highlighted the clinical relevance of more than half the prescriptions considered inappropriate according to current PPI criteria in the elderly. It underlines the interest of a new PPI detection tool for elderly patients with psychiatric disorders.

Determinants of successful opioid deprescribing: Insights from French pain physicians-A qualitative study.

BACKGROUND: Long-term use of opioids does not result in significant clinical improvement and has shown more adverse than beneficial effects in chronic pain conditions. When opioids cause more adverse effects than benefits for the patient, it may be necessary to initiate a process of deprescribing. AIM: To explore the perceptions of French pain physicians regarding the process of opioid deprescribing in patients experiencing chronic non-cancer and to generate an understanding of the barriers and levers to the deprescribing process. METHODS: We conducted a multicentric observational study with qualitative approach. Individual semi-structured interviews exploring pain physicians' perceptions, beliefs, and representations to assess the determinants of opioid deprescribing with an interview guide were used. After checking the transcripts, an inductive and independent thematic analysis of the interviews was to extract meaningful themes from the dataset. RESULTS: Twelve pain physicians were interviewed. The main obstacles to deprescribing revolved around patient-specific attributes, characteristics of the opioids themselves, and limitations within the current healthcare system, that hinder optimal patient management. Conversely, patient motivation and education, recourse to hospitalization in a Pain Department with multidisciplinary care, follow-up by the general practitioner, and training and information dissemination among patients and clinicians emerged as facilitative elements for opioid deprescribing. CONCLUSION: This study underscores the needs to improve the training of healthcare professionals, the effective communication of pertinent information to patients, and the establishment of a therapeutic partnership with the patient. It is therefore essential to carry out the deprescribing process in a collaborative and interprofessional manner, encompassing both pharmaceutical and non-pharmaceutical strategies.

Outcomes in deprescribing implementation trials and compliance with expert recommendations: a systematic review.

BACKGROUND: Deprescribing, defined as discontinuing or reducing the dose of medications that are no longer needed or for which the risks outweigh the benefits is a way to reduce polypharmacy. In 2022, the US Deprescribing Research Network (USDeN) published recommendations concerning the measurement of outcomes for deprescribing intervention studies. The objectives of this systematic review were to identify the outcome categories used in deprescribing intervention trials and to relate them to the previously published recommendations. METHODS: We searched MEDLINE, Embase, PsychInfo, and the Cochrane library from January 2012 through January 2022. Studies were included if they were randomized controlled trials evaluating a deprescribing intervention. After data extraction, outcomes were categorized by type: medication outcomes, clinical outcomes, system outcomes, implementation outcomes, and other outcomes based on the previously published recommendations. RESULTS: Thirty-six studies were included. The majority of studies focused on older adults in nursing homes and targeted inappropriate medications or polypharmacy. In 20 studies, the intervention was a medication review; in seven studies, the intervention was educational or informative; and three studies based their intervention on motivational interviewing or patient empowerment. Thirty-one studies presented a medication outcome (primary outcome in 26 studies), 25 a clinical outcome, 18 a system outcome, and seven an implementation outcome. Only three studies presented all four types of outcomes, and 10 studies presented three types of outcomes. CONCLUSIONS: This review provides an update on the implementation of gold standard deprescribing studies in clinical practice. Implementation outcomes need to be developed and specified to facilitate the implementation of these practices on a larger scale and clinical outcome need to be prioritized. Finally, this review provides new elements for future real-life deprescribing studies.

A comparative study of three-dimensional cone-beam CT sialography and MR sialography for the detection of non-tumorous salivary pathologies.

BACKGROUND: Imaging of the salivary ductal system is relevant prior to an endoscopic or a surgical procedure. Various imaging modalities can be used for this purpose. The aim of this study was to compare the diagnostic capability of three-dimensional (3D)-cone-beam computed tomography (CBCT) sialography versus magnetic resonance (MR) sialography in non-tumorous salivary pathologies. METHODS: This prospective, monocenter, pilot study compared both imaging modalities in 46 patients (mean age 50.1 ± 14.9 years) referred for salivary symptoms. The analyses were performed by two independent radiologists and referred to identification of a salivary disease including sialolithiasis, stenosis, or dilatation (primary endpoint). The location and size of an abnormality, the last branch of division of the salivary duct that can be visualized, potential complications, and exposure parameters were also collected (secondary endpoints). RESULTS: Salivary symptoms involved both the submandibular (60.9%) and parotid (39.1%) glands. Sialolithiasis, dilatations, and stenosis were observed in 24, 25, and 9 patients, respectively, with no statistical differences observed between the two imaging modalities in terms of lesion identification (p1 = 0.66, p2 = 0.63, and p3 = 0.24, respectively). The inter-observer agreement was perfect (> 0.90) for lesion identification. MR sialography outperformed 3D-CBCT sialography for visualization of salivary stones and dilatations, as evidenced by higher positive percent agreement (sensitivity) of 0.90 [95% CI 0.70-0.98] vs. 0.82 [95% CI 0.61-0.93], and 0.84 [95% CI 0.62-0.94] vs. 0.70 [95% CI 0.49-0.84], respectively. For the identification of stenosis, the same low positive percent agreement was obtained with both procedures (0.20 [95% CI 0.01-0.62]). There was a good concordance for the location of a stone (Kappa coefficient of 0.62). Catheterization failure was observed in two patients by 3D-CBCT sialography. CONCLUSIONS: Both imaging procedures warrant being part of the diagnostic arsenal of non-tumorous salivary pathologies. However, MR sialography may be more effective than 3D-CBCT sialography for the identification of sialolithiasis and ductal dilatations. TRIAL REGISTRATION: NCT02883140.

Highly Conserved gsc1 Gene of Pneumocystis jirovecii in Patients with or without Prior Exposure to Echinocandins.

Echinocandins are noncompetitive inhibitors of the GSC1 subunit of the enzymatic complex involved in synthesis of 1,3-beta-d-glucan, a cell wall component of most fungi, including Pneumocystis spp. Echinocandins are widely used for treating systemic candidiasis and rarely used for treating Pneumocystis pneumonia. Consequently, data on P. jirovecii gsc1 gene diversity are still scarce compared to that for the homologous fks1 gene of Candida spp. In this study, we analyzed P. jirovecii gsc1 gene diversity and the putative selection pressure of echinocandins on P. jirovecii. gsc1 gene sequences of P. jirovecii specimens from two patient groups were compared. One group of 27 patients had prior exposure to echinocandins, whereas the second group of 24 patients did not, at the time of P. jirovecii infection diagnoses. Two portions of the P. jirovecii gsc1 gene, HS1 and HS2, homologous to hot spots described in Candida spp., were sequenced. Three single-nucleotide polymorphisms (SNPs) at positions 2204, 2243, and 2303 close to the HS1 region and another SNP at position 4540 more distant from the HS2 region were identified. These SNPs represent synonymous mutations. Three gsc1 HS1 alleles, A, B, and C, and two gsc1 HS2 alleles, a and b, and four haplotypes, Ca, Cb, Aa, and Ba, were defined, without significant difference in haplotype distribution in both patient groups (P = 0.57). Considering the identical diversity of P. jirovecii gsc1 gene and the detection of synonymous mutations in both patient groups, no selection pressure of echinocandins among P. jirovecii microorganisms can be pointed out so far.

Exploring the factors influencing adherence to oral anticancer drugs in patients with digestive cancer: a qualitative study.

PURPOSE: The aim of this study was to explore the beliefs, perceptions and representations of patients in order to identify the determinants of oral anticancer drugs adherence and to take action in current practice to improve patient support in digestive oncology. METHODS: We constructed a semi-directed interview guide which aimed to explore the patient's relationship with medication, their health history, their experiences at the time of the announcement of treatment, their confidence, their fears, their motivations to adhere to their treatment and the constraints linked to their treatment. The data were analysed and discussed using a thematic approach. RESULTS: Seventeen patients agreed to participate in the study. The median age was 60 years. Ten patients had colorectal cancer, 3 patients had hepatocellular carcinoma, 3 patients had gastrointestinal stromal tumour and 1 patient had neuroendocrine pancreatic tumour. We identified five categories of factors influencing adherence: demographic and socioeconomic, disease-related, treatment-related, care system-related, and patient representation and pathways' factors. A majority of patients emphasised the importance of family support in the adherence process and the convenience of per os treatment compared to other intravenous treatments. However, several negative determinants emerged such as the toxicity of the treatment, fears of forgetting to take the medication, difficulties with the galenic formulation and negative beliefs of the family. CONCLUSION: This study demonstrates the need to address the different dimensions of the patient in order to understand his or her behaviour with regard to adherence and to identify the levers for improvement.

Pharmaceutical cancer care for haematology patients on oral anticancer drugs: Findings from an economic, clinical and organisational analysis.

OBJECTIVE: The clinical benefit of pharmaceutical cares in improving the quality-of-care outcomes is well demonstrated. Clinical pharmacy services are not systematically deployed in cancer units in the absence of economic data. The aim of this prospective, observational 1-year study was to evaluate the clinical, economic and organisational impacts of pharmaceutical care into a multidisciplinary day hospital for patients treated with oral cancer drugs. METHODS: All pharmacists' interventions (PI) were documented and their impact and the probability of adverse drug events were assessed using the clinical, economic and organisational tool. RESULTS: Among 360 admissions, an average of 1.81 PI per admission was accepted. Among 452 PI leading to a clinical benefit on the patient, 16.9% had a major impact, and 1.9% had an impact on survival. The large majority of PIs (87%) increased the quality-of-care organisation. The budget impact model showed a total cost savings and cost avoidance of €539,047 per year and a cost-benefit ratio of 7.07:1. The direct cost-benefit was €201,741, and the cost avoidance was €337,306. CONCLUSION: Multidisciplinary care and pharmaceutical care are key elements to improve cancer patients' outcomes and avoid evitable healthcare costs.

Anticancer agents and phytotherapy: Interactions that are often unrecognized.

Phytotherapy is the main complementary medicine for which patients afflicted with cancer have recourse but the associated consumption of phytotherapy products gives rise to a risk of interaction with anticancer agents. The aim of this prospective study was to measure the prevalence of the consumption of phytotherapy products as well as their interactions with anticancer agents in a cohort of patients from January 2018 to August 2019. Patients hospitalized in the conventional hematology unit and outpatients who had their prescriptions for oral anticancer agents filled at the hospital pharmacy were questioned about consumption of phytotherapy products by pharmacy externs trained in pharmaceutical interviews. Among the 110 hospitalized patients who answered the questionnaire, 40% (n = 44) used phytotherapy and 5 of them continued to consume it during the cycles of injectable chemotherapy. As a result, 10 interactions were found between the plants and the anticancer agents (prevalence of 27%). Among the 59 outpatients, 17% (n = 10) consumed phytotherapy. Eight interactions were identified (prevalence of 80%). The potential consequences were an increase or a decrease in the concentration of the anticancer agents and an increase in the risk of bleeding, hepatoxicity, and hypokalemia. The consumption of phytotherapy was unknown by a health professional for 44% of hospitalized patients and 60% of the outpatients. The risk of interactions between plants and anticancer agents is not negligible and professionals should be cognizant of this in their daily practice. The availability of tools for training and detection of interactions is indispensable for managing patients undergoing onco-hematology treatments.

A murine model of Staphylococcus aureus infected chronic diabetic wound: A new tool to develop alternative therapeutics.

Diabetic wound infection is a frequent complication that may result in limb amputation. To develop new treatment strategies in response to increasing bacterial resistance, animal models are needed. We created a diabetic mouse model with chronically infected wounds. Diabetes was induced using streptozotocin, and wounds were performed using a biopsy punch, and then infected with a clinical strain of Staphylococcus aureus. Chronification was reached by delaying healing thanks to chemical products (aminotriazole and mercaptosuccinic acid). Overall survival, as well as clinical, bacteriological and immunological data in skin, blood and spleens were collected at days 1, 7, and 14 after wounding. After a transient bacteremia proved by bacteria presence in spleen and kidneys in the first days after wounding, infected mice showed a chronic infection, with a bioburden impairing the healing process, and bacteria persistence compared to control mice. Infected mice showed gradual increasing skin levels of IL-17A compared to control mice that resulted in an IL-17/IFN-γ inbalance, pointing out a localized Th17 polarization of the immune response. Whether infected or not, the skin level of IL-10 decreased dramatically at days 1 and 7 after wounding, with an increase observed only in the control mice at day 14. After a decrease at day 1 in both groups, spleen IL-10 showed a rather steady level at days 7 and 14 in the control group compared with the decrease observed in the infected group. The spleen IL-10/IFN-γ ratio showed a systemic inflammatory response with Th1 polarization. Therefore, this model provides useful data to study wound healing. It is easy to reproduce, affordable and offers clinical and biological tools to evaluate new therapeutics.

[Implementation of pharmaceutical consultations in digestive oncology in a teaching hospital: one-year outcomes]. / Mise en place de consultations pharmaceutiques d'initiation en oncologie digestive dans un centre hospitalo-universitaire : bilan à un an.

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.

Exploration of the barriers and enablers of benzodiazepines deprescribing in prisons: A qualitative study among health and social care professionals.

BACKGROUND: The prison environment is a place of high consumption of benzodiazepines (BZDs) due to the anxiety and sleep disturbances, mental disorders, detoxification and trafficking. OBJECTIVE: The study aims to explore experiences of health and social care professionals on the use of BZDs in prisons, as well as the barriers and enablers to their deprescribing. METHOD: Semistructured individual interviews with professionals working in a prison setting were performed between March and April 2022, based on an interview guide. They were recorded and transcribed using the NVivo software. A qualitative analysis using an inductive approach based on a thematic analysis was performed. RESULTS: Sixteen health professionals were interviewed, including psychiatrists, general practitioners, nurses, pharmacists, psychologists, musicologists and pharmacy technicians. The identified barriers to deprescribing BZDs were problems of coordination between prescribers, lack of time and alternatives. Concerning the enablers, therapeutic education groups, staff's awareness of the irrelevance of some medication and multi-professional advice were identified. DISCUSSION: This study highlights the similarities in deprescribing difficulties between prison and other settings. Some of the levers identified in our study have shown their effectiveness in different settings. CONCLUSION: Deprescribing is done most of the time in good conditions but requires an additional delay compared to the outside environment.

Deep continuous sedation at the patient's request until death in a palliative care unit: retrospective study.

OBJECTIVES: Limited descriptive data are available on continuous and deep sedation maintained until death (CDSUD) at the patient's request in palliative care units. This study aimed to describe such practices in the context of refractory suffering or after a request to stop life-sustaining treatment, evaluating the duration and dosage of sedative treatments used. METHODS: This retrospective observational study included consecutively hospitalised patients in a palliative care unit from January 2020 to December 2021. Data on patient profiles, reasons for the sedation request, duration of sedation and doses of sedatives were collected. RESULTS: Among 42 patients who underwent CDSUD, 79% occurred due to refractory suffering. In cases of sedation following a request to stop life support, high-dose corticosteroid therapy was the most commonly involved life-sustaining treatment. Midazolam was always the first-line sedative treatment. Chlorpromazine was added in 79% of cases, and propofol in 40%, to achieve a deep level of sedation. The mean maximum doses of midazolam, chlorpromazine and propofol were 7.6 mg/hour (±1.9), 3.3 mg/hour (±0.9) and 1.7 mg/kg/hour, respectively. The average duration of sedation was 37 hours. CONCLUSIONS: This study provides new descriptive elements on CDSUD. Notably, it highlights the use of second-line sedative molecules, such as propofol.

Are the deprescribing guidelines for proton pump inhibitors in palliative care applicable? A monocentric observational study.

OBJECTIVES: Proton pump inhibitors (PPIs) are among the most commonly prescribed medications. The aim of this study was to assess the appropriateness of prescribing PPIs in the palliative care unit on admission and during hospitalisation to determine the applicability of deprescribing recommendations. METHODS: A monocentric observational study was conducted over a 6-month period in 2020 in a university palliative care unit. Data on indication, starting date, dose and posology were collected at discharge from the medical record and by contacting the prescriber. A physician and a pharmacist evaluated PPI prescription appropriateness according to guidelines. RESULTS: 131 patients (mean age: 69.5 years; 82% with cancer) were included. Prior to admission, 41% (54/131) of patients were already prescribed PPIs. During hospitalisation, 50% of prescriptions were discontinued, while 12% were initiated. The indication was known for 50% of patients on admission and 59% during their stay. Among patients with PPI prescriptions, 56% had a relevant indication on admission, and 63% during their stay. The prevalence of potential drug interactions was low (<1/10). CONCLUSIONS: While PPIs remain essential for specific indications, this study highlights their excessive prescription even during palliative care. Implementing deprescribing recommendations in this population is crucial to optimise treatment plans.

DEprescribing: Perceptions of PAtients living with advanced cancer. A multicentre, prospective mixed observational study protocol.

INTRODUCTION: Polypharmacy in patients with advanced cancer represents a major public health problem, leading to risk of iatrogenesis, decrease of quality of life and increase of healthcare costs. In the field of geriatrics, health policies have been developed to address polypharmacy through the use of deprescribing tools. Recently, palliative care initiatives have been introduced, yet these have not fully considered the specificities of this population, particularly their perceptions. It is therefore important to better understand patients' perceptions of deprescribing in order to adapt tools and actions to make these approaches more effective. OBJECTIVES: The aim is to investigate patients' perceptions of deprescribing in palliative oncology care, and to explore factors that may influence patients' attitudes and beliefs about deprescribing and to validate a specific questionnaire (rPATD) in this population. An ancillary study will investigate the relationship between patients' health literacy and their perception of deprescribing. METHOD: A prospective, observational, multicenter study will be conducted using a sequential mixed exploratory design in a population of patients living with advanced cancer and with a physician-estimated life expectancy of less than 1 year. The study will include an initial qualitative phase. Individual semi-structured interviews using a descriptive approach (thematic analysis) will be conducted (upon saturation). Following analysis of the qualitative data, a quantitative study including 300 patients will be realized to meet secondary objectives. Several data will be collected and 2 self-questionnaires will be administered: the BMQ (beliefs about medicine) and rPATD (perception of deprescribing) possibly supplemented by additional items if required by the qualitative analysis. The auxiliary study will be conducted during this second phase, using a validated self-questionnaire to assess patients' level of literacy. CONCLUSION: The disparate outcomes will facilitate the understanding of the perception of deprescribing in palliative oncology care, enabling the development of tailored approaches adapted to this population. TRIAL REGISTRATION: ClinicalTrials Identifier: NCT06193083.

Involving community pharmacists in interprofessional collaboration in primary care: a systematic review.

BACKGROUND: The World Health Organization supports interprofessional collaboration in primary care. On over the past 20 years, community pharmacists had been taking a growing number of new responsibilities and they are recognized as a core member of collaborative care teams as patient-centered care providers. This systematic review aimed to describe interprofessional collaboration in primary care involving a pharmacist, and its effect on patient related outcomes. METHODS: A systematic review of randomized controlled trials cited in the MEDLINE, EMBASE, PsycInfo and CINAHL in English and French was conducted from inception to November 2022. Studies were included if they described an intervention piloted by a primary care provider and included a pharmacist and if they evaluated the effects of intervention on a disease or on patient related outcomes. The search generated 3494 articles. After duplicates were removed and titles and abstracts screened for inclusion, 344 articles remained. RESULTS: Overall, 19 studies were included in the review and assessed for quality. We found 14 studies describing an exclusive collaboration between physician and pharmacist with for all studies a three-step model of pharmacist intervention: a medication review, an interview with the patient, and recommendations made to physician. Major topics in the articles eligible for inclusion included cardiovascular diseases with blood pressure, diabetes, dyslipidemia, and risk of cardiovascular diseases. Positive effects concerned principally blood pressure. CONCLUSIONS: Collaboration involving pharmacists is mainly described in relation to cardiovascular diseases, for which patient-centered indicators are most often positive. It underscores the need for further controlled studies on pharmacist-involved interprofessional collaboration across various medical conditions to improve consensus on core outcomes measures.

A systematic review of the impact of simulation on students' confidence in performing clinical pharmacy activities.

BACKGROUND: Although confidence does not automatically imply competence, it does provide pharmacy students with a sense of empowerment to manage a pharmacotherapeutic problem independently. Among the methods used in higher education, there is growing interest in simulation. AIM: To evaluate the impact of simulation on pharmacy students' confidence in performing clinical pharmacy activities. METHOD: Articles that reported the use of simulation among pharmacy students with fully described outcomes about confidence were included. Studies for which it was impossible to extract data specific to pharmacy students or simulation were excluded. The search was carried out in Medline, Embase, Lissa and PsycInfo from inception to August the 31th, 2022. The results were synthesized into 4 parts: confidence in collecting information, being an expert in a procedure/pathology, counselling and communicating, and other results. The quality assessment of included studies was conducted using the Mixed Methods Appraisal Tool "MMAT" tool. RESULTS: Among the 39 included articles, the majority were published in the last 5 years and conducted in the United States. The majority included pharmacy students in years 1 through 3 (69.2%). The most common study design was the pre-post uncontrolled design (66.7%). Studies measuring the effects of human and/or virtual simulation were mainly focused on confidence to counsel and/or communicate with patients and colleagues (n = 20). Evaluations of the effects of these types of simulation on confidence in information gathering by health professionals were also well represented (n = 16). CONCLUSION: Simulation-based training generally yielded positive impact on improving pharmacy students' confidence in performing clinical pharmacy activities. Rigorous assessment methods and validated confidence questionnaires should be developed for future studies.

The cost of potentially inappropriate medications for older adults in Canada: A comparative cross-sectional study.

BACKGROUND: Potentially inappropriate medications (PIMs) are medications whereby the harms may outweigh the benefits for a given individual. Although overprescribed to older adults, their direct costs on the healthcare system are poorly described. METHODS: This was a cross-sectional study of the cost of PIMs for Canadians aged 65 and older, using adapted criteria from the American Geriatrics Society. We examined prescription claims information from the National Prescription Drug Utilization Information System in 2021 and compared these with 2013. The overall levels of inflation-adjusted total annual expenditure on PIMs, average cost per quarterly exposure, and average quarterly exposures to PIMs were calculated in CAD$. RESULTS: Exposure to most categories of PIMs decreased, aside from gabapentinoids, proton pump inhibitors, and antipsychotics, all of which increased. Canadians spent $1 billion on PIMs in 2021, a 33.6% reduction compared with 2013 ($1.5 billion). In 2021, the largest annual expenditures were on proton pump inhibitors ($211 million) and gabapentinoids ($126 million). The quarterly amount spent on PIMs per person exposed decreased from $95 to $57. In terms of mean cost per person, opioids and antipsychotics were highest ($138 and $118 per exposure). Some cost savings may have occurred secondary to an observed decline of 16.4% in the quarterly rate of exposure to PIMs (from 7301 per 10,000 in 2013 to 6106 per 10,000 in 2021). CONCLUSIONS: While expenditures on PIMs have declined in Canada, the overall cost remains high. Prescribing of some seriously harmful classes of PIMs has increased and so directed, scalable interventions are needed.

Medication Deprescribing in Patients Receiving Hemodialysis: A Prospective Controlled Quality Improvement Study.

Rationale & Objective: Patients treated with dialysis are commonly prescribed multiple medications (polypharmacy), including some potentially inappropriate medications (PIMs). PIMs are associated with an increased risk of medication harm (eg, falls, fractures, hospitalization). Deprescribing is a solution that proposes to stop, reduce, or switch medications to a safer alternative. Although deprescribing pairs well with routine medication reviews, it can be complex and time-consuming. Whether clinical decision support improves the process and increases deprescribing for patients treated with dialysis is unknown. This study aimed to test the efficacy of the clinical decision support software MedSafer at increasing deprescribing for patients treated with dialysis. Study Design: Prospective controlled quality improvement study with a contemporaneous control. Setting & Participants: Patients prescribed ≥5 medications in 2 outpatient dialysis units in Montréal, Canada. Exposures: Patient health data from the electronic medical record were input into the MedSafer web-based portal to generate reports listing candidate PIMs for deprescribing. At the time of a planned biannual medication review (usual care), treating nephrologists in the intervention unit additionally received deprescribing reports, and patients received EMPOWER brochures containing safety information on PIMs they were prescribed. In the control unit, patients received usual care alone. Analytical Approach: The proportion of patients with ≥1 PIMs deprescribed was compared between the intervention and control units following a planned medication review to determine the effect of using MedSafer. The absolute risk difference with 95% CI and number needed to treat were calculated. Outcomes: The primary outcome was the proportion of patients with one or more PIMs deprescribed. Secondary outcomes include the reduction in the mean number of prescribed drugs and PIMs from baseline. Results: In total, 195 patients were included (127, control unit; 68, intervention unit); the mean age was 64.8 ± 15.9 (SD), and 36.9% were women. The proportion of patients with ≥1 PIMs deprescribed in the control unit was 3.1% (4/127) vs 39.7% (27/68) in the intervention unit (absolute risk difference, 36.6%; 95% CI, 24.5%-48.6%; P < 0.0001; number needed to treat = 3). Limitations: This was a single-center nonrandomized study with a type 1 error risk. Deprescribing durability was not assessed, and the study was not powered to reduce adverse drug events. Conclusions: Deprescribing clinical decision support and patient EMPOWER brochures provided during medication reviews could be an effective and scalable intervention to address PIMs in the dialysis population. A confirmatory randomized controlled trial is needed.

Patients treated with dialysis are commonly prescribed multiple medications, some of which are potentially inappropriate medications (PIMs). PIMs can increase a patient's pill burden and are associated with an increased risk of harm (some examples include falls, fractures, and hospitalization). Deprescribing is a proposed solution that aims to highlight medications that can be stopped, reduced, or switched to a safer option, under supervision of a health care provider. We aimed to determine if a quality improvement intervention in the dialysis unit could increase deprescribing compared to usual care. The study took place in 2 outpatient hemodialysis units where usual care involves nurses and nephrologists performing medication reviews twice a year. The intervention was a deprescribing report that was generated with the help of a software tool called MedSafer, along with brochures for patients with information on PIMs they were taking. In the intervention unit, we increased the number of patients who had a medication safely deprescribed by 36.6% more than on the control unit. Although the study was small, a future larger study in dialysis patients might show that a computer software such as MedSafer can prevent harmful complications from taking too many medications.

Physicians' views on pharmacists' involvement in hospital deprescribing: A qualitative study on proton pump inhibitors.

BACKGROUND: Clinical pharmacists have a pivotal role in the management of the patient's medication. However, it is necessary to know how pharmacist-mediated deprescribing could be implemented in a hospital setting according to hospital physicians. OBJECTIVE: To explore physicians' views on the involvement of hospital pharmacists in the deprescribing process using the example of PPIs. METHODS: A qualitative study using two focus groups with hospital physicians was conducted to determine their attitudes regarding deprescribing initiated by the hospital pharmacist. The interviews were recorded and transcribed using the NVivo analysis software. A thematic analysis led to a categorization of all the verbatims. RESULTS: Hospital doctors are reluctant to deprescribe drugs initiated by a colleague and feel that it is the responsibility of the general practitioner (GP), who fails to do so due to lack of time. In this situation, the hospital pharmacist is in the best position to deprescribe because of his/her expertise in drug therapy. This should be a discussion between the hospital pharmacist, the hospital doctor, the GP and the patient. Deprescribing should always be adapted to the patient's context. CONCLUSION: Hospital physicians are open to a pharmacist-mediated, patient-centred approach to deprescribing as long as the GP is involved.
