Medication Review: What's in a Name and What Is It about?

BACKGROUND: Medication review is a multifaceted service aimed at optimizing the use of medicines and enhancing the health outcomes of patients. Due to its complexity, it is crucial to clearly describe the service, its variants, and its components to avoid confusion and ensure a better understanding of medication review among healthcare providers. AIM: This study aims to bring clarity to the origins, definitions, abbreviations, and types of medication reviews, together with the primary criteria that delineate key features of this service. METHOD: A narrative review approach was employed to clarify the diverse terminology associated with "medication review" services. Relevant references were initially identified through searches on PubMed and Google Scholar, complementing the existing literature known to the authors. RESULTS: The study uncovers a complicated and sometimes convoluted history of "medication review" in different regions around the world. The initial optimization of medicine use had an economic purpose before evolving subsequently into a more patient-oriented approach. A selection of abbreviations, definitions, and types were outlined to enhance the understanding of the service. CONCLUSIONS: The study underscores the urgent need for comprehensive information and standardization regarding the content and quality of the services, collectively referred to as "medication review".

A quality improvement study of the implementation and initial results of a pragmatic clinical decision support system in the community pharmacy setting.

BACKGROUND: A six year collaboration between academics, community pharmacists and informaticians, led to the development of nine guidelines for a clinical decision support system, enhancing community pharmacists' ability to address drug-related problems and improve care. AIM: The objective of this study was to assess the effectiveness of clinical decision support system rules in enhancing medication management within the community pharmacy setting. This was achieved through retrospective monitoring of real-world usage and measuring the pharmacotherapeutic impact of the rules. METHOD: In 2019, a retrospective observational evaluation appraised the acceptance rate of the clinical decision support system components in 490 Belgian pharmacies. Among these, 51 pharmacies underwent a longitudinal analysis involving (i) co-prescription of methotrexate and folic acid, (ii) gastroprotection with non-steroidal anti-inflammatory drugs, and (iii) drug combinations causing QT prolongation. The study period spanned one year pre-launch, one year post-launch, and two years post-launch. RESULTS: Of the targeted pharmacies, 80% used 7 of the 9 rules. After four years, methotrexate-folic acid co-prescription increased 4%, reaching 79.8%. Gastroprotection improved by 3% among older patients and 7.47% in younger individuals (< 70 year) with multiple risk factors. The QT prolongation rules faced implementation difficulties. CONCLUSION: Pharmacists' acceptance of the developed rules was high and coincided with a decline in drug-related problems, holding potential public health impact. This real-world data can inform the future implementation of such systems, as it demonstrated the need for more detailed data-gathering and more intensive training of pharmacists in the handling of more complex problems such as QT prolongation.

Key elements in the quality assessment of a type 3 medication review.

Background: Medication reviews are a structured evaluation of a patient's pharmacotherapy with the aim of optimizing medicines use and improving health outcomes. This entails detecting drug related problems and recommending interventions. A high level of quality is essential for the successful implementation of this service in community pharmacies but currently there is no instrument or tool to assess that overall quality. Aim: This study investigated the development of quality criteria of type 3 medication reviews (MR3s). Methods: After surveying the literature, an electronic questionnaire was developed to gather information about quality criteria for MR3. This survey, in Dutch, was distributed electronically. Four groups were queried: 1) pharmacists, mainly working in the Netherlands, involved in practice research and contacted through the PRISMA (Practice Research In Collaboration With Pharmacists) foundation, 2) Belgian pharmacy academics and pharmacists active in professional associations (APA), 3) Belgian pharmacists trained in medication review (MR) by the Royal Pharmacists Association of Antwerp (KAVA) and 4) Belgian pharmacy students. The survey included 57 criteria, divided into eight domains, which were ranked according to their importance by the participants. The results were analyzed statistically using the nonparametric Kruskal-Wallis test. Results: The survey was completed by 95 participants, including 42 PRISMA pharmacists, 19 APA pharmacists, 18 KAVA pharmacists and 16 pharmacy students. Opinions from participants from the different groups overlapped significantly. The use of simple and understandable language in the conversation with the patient was considered essential by the majority. Discussing the usefulness and purpose of a MR3 with the patient was also rated highly by all groups. Differences of opinion were present in aspects about laboratory values, the use of specific tools, and reporting to and consultation with the treating physician. The participants themselves formulated a limited number of additional assessment criteria. Conclusion: There was widespread agreement on the hierarchy of the quality assessment criteria for MR3s. Minor differences were related to the experience of the participants. With these results and a small number of suggested extra criteria, a quality assessment instrument for MR3 can be created.

Psychiatrists and other medical professionals in Belgium show a substantial lack of knowledge about poverty.

The bidirectional relationship between poverty and poor physical and mental health is well-known. All physicians should have sufficient knowledge on poverty as a social determinant and its impact on (mental) health. The knowledge of poverty in physicians is seldom investigated. An online and paper survey was circulated in March/April 2022 in Belgium, to assess physician's opinions about and attitudes toward patients in poverty. Not only was interest in the subject rather low, but there were also substantial contradictions in the responses. The lack of knowledge about poverty among physicians leads to reduced quality of medical care for this target group. This is an individual medical-ethical and societal problem. We suggest 10 point-action plan for policymakers, educational institutions, and physicians.

Development of a toolkit to improve interprofessional collaboration and integration in primary care using qualitative interviews and co-design workshops.

Background: Despite numerous attempts to improve interprofessional collaboration and integration (IPCI) in primary care, patients, care providers, researchers, and governments are still looking for tools and guidance to do this more efficiently. To address these issues, we decided to develop a generic toolkit, based on sociocracy and psychological safety principles, to guide care providers in their collaboration within and outside their practice. Finally, we reasoned that, in order to obtain integrated primary care, different strategies should be combined. Methods: Development of the toolkit consisted of a multiyear co-development process. Data originating from 65 care providers, through 13 in-depth interviews and five focus groups were analysed and subsequently evaluated in eight co-design workshop sessions, organised with a total of 40 academics, lecturers, care providers and members of the Flemish patient association. Findings from the qualitative interviews and co-design workshops were gradually, and inductively adapted and transformed into the content for the IPCI toolkit. Results: Ten themes were identified: (i) awareness of the importance of interprofessional collaboration, (ii) the need for a self-assessment tool to measure team performance, (iii) preparing a team to use the toolkit, (iv) enhancing psychological safety, (v) developing and determining consultation techniques, (vi) shared decision making, (vii) developing workgroups to tackle specific (neighbourhood) problems, (viii) how to work patient-centred, (ix) how to integrate a new team member, and (x) getting ready to implement the IPCI toolkit. From these themes, we developed a generic toolkit, consisting of eight modules. Conclusion: In this paper, we describe the multiyear co-development process of a generic toolkit for the improvement of interprofessional collaboration. Inspired by a mix of interventions from in and outside healthcare, a modular open toolkit was produced that includes aspects of Sociocracy, concepts as psychological safety, a self-assessment tool and other modules concerned with meetings, decision-making, integrating new team members and population health. Upon implementation, evaluation and further development and improvement, this compounded intervention should have a beneficial effect on the complex problem of interprofessional collaboration in primary care.

Patient experiences and opinions on medication review: a qualitative study.

BACKGROUND: Medication reviews are a structured critical evaluation of a patient's pharmacotherapy, carried out by a healthcare professional, but are not yet a routine pharmaceutical service in Belgium. A pilot project to initiate an advanced medication review (= type 3 medication review) in community pharmacies was set up by the Royal Pharmacists' Association of Antwerp. AIM: To investigate the experiences and opinions of patients who participated in this pilot project. METHOD: Qualitative study through semi-structured interviews with participating patients. RESULTS: Seventeen patients from six different pharmacies were interviewed. The medication review process with the pharmacist was perceived as positive and instructive by fifteen interviewees. The extra attention that the patient received was highly appreciated. However, the interviews revealed that patients did not fully understand the purpose and structure of this new service or were aware of the subsequent contact and feedback with the general practitioner. Medication reviews in the home setting put patients more at ease, were highly appreciated, and enabled also to address practical problems such as drug dosing or storage requirements. CONCLUSION: This qualitative study analysed patients' experiences during a pilot project on the implementation of type 3 medication review. Although most patients were enthusiastic about this new service, a lack of patients' understanding of the whole process was also observed. Therefore, better communication to patients by pharmacists and general practitioners about the goals and components of this type of medication review is needed, with the added benefit of increased efficiency.

Do the lockdown-imposed changes in a wastewater treatment plant catchment's socio-demographics impact longitudinal temporal trends in psychoactive pharmaceutical use?

Wastewater-based epidemiology (WBE) includes the analysis of human metabolic biomarkers of xenobiotics in influent wastewater. WBE complements existing drug utilization approaches and provides objective, spatio-temporal information on the consumption of pharmaceuticals in the general population. This approach was applied to 24-h composite influent wastewater samples from Leuven, Belgium. Daily samples were analysed from September 2019 to December 2019 (n = 76), and on three days of the week (Monday, Wednesday, Saturday) from January 2020 to April 2022 (n = 367). Sample analysis consisted of 96-well solid-phase extraction and liquid chromatography coupled to tandem mass spectrometry. Measured concentrations of 21 biomarkers for antidepressant and opioid use were converted to population-normalized mass loads (PNML) by considering the flow rate and catchment population. To capture population movements, mobile phone data was used. Amitriptyline, hydroxy-bupropion, norcitalopram, citalopram, normirtazapine, trazodone, O-desmethylvenlafaxine, codeine, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP), methadone, morphine, O-desmethyltramadol, and tramadol were included in the temporal assessment since concentrations were above the lower limit of quantification. The PNML of most biomarkers increased (with 3-119 %) throughout the sampling period. The population disruption during the COVID-19 pandemic led to a major change in the socio-demographics of the catchment area, resulting in temporal differences in the PNML of the different biomarkers. As such, higher PNML were observed during the different lockdown phases, which were characterized by the outflow of university students and a decreasing commuting in and out the catchment area. The effects of the fluctuating socio-demographics of the catchment population were further evidenced by the different week-weekend pattern of PNMLs over the course of the sampling campaign. Mean parent/metabolite ratios (i.e., citalopram/norcitalopram, tramadol/O-desmethyltramadol, venlafaxine/O-desmethylvenlafaxine, and methadone/EDDP) remained relatively stable throughout the entire sampling campaign (RSD% below 25 % for all ratios, except for methadone/EDDP) and therefore were not affected by this population change.

Comprehensive Medication Management Services with a Holistic Point of View, a Scoping Review.

Implementing Comprehensive Medication Management (CMM) services uncovered the importance of the totality of the patient's perspective in this process. The holistic approach takes into account the physical, mental and emotional well-being of individuals, as well as their socioeconomic circumstances. The aim of this study was to characterize the scientific evidence associated with CMM services that included this holistic approach. A scoping review was conducted based on Arksey and O'Malley's method. Searches were performed in Google Scholar for papers published between 2010 and 2020 in English, Spanish and Portuguese. Study design, health contexts, sample of patients, results obtained, barriers and facilitators, and the integration of a holistic approach were determined. Two hundred and eighteen papers were evaluated, most of which focused on the implementation of this service through prospective observational studies. A minority of studies reported on a holistic approach, a smaller number examined the effect of social determinants of health, the patient's medication experiences and the pharmacotherapy outcomes from the patient's perspective. Despite the progress achieved, most of the referents do not yet reflect a broader view of the patient's life situation and its relationship to pharmacotherapy and the ways in which the pharmacist implements holistic elements to solve or prevent drug-related problems.

How do people living with chronic conditions and their informal caregivers experience primary care? A phenomenological-hermeneutical study.

AIMS AND OBJECTIVES: Gaining insight in how people living with chronic conditions experience primary healthcare within their informal network. BACKGROUND: The primary healthcare system is challenged by the increasing number of people living with chronic conditions. To strengthen chronic care management, literature and policy plans point to a person-centred approach of care (PCC). A first step to identify an appropriate strategy to implement PCC is to gain more insight into the care experiences of these people and their informal caregivers. DESIGN: A phenomenological-hermeneutical philosophy is used. The study is in line with the Consolidated Criteria for Reporting Qualitative Research Guidelines (COREQ). METHOD: In-depth, semi-structured interviews with people living with chronic conditions and informal caregiver dyads (PCDs) (n = 16; 32 individuals) were conducted. An open-ended interview guide was used to elaborate on the PCDs' experiences regarding primary care. A purposive, maximal variation sampling was applied to recruit the participants. RESULTS: Based on sixteen PCDs' reflections, ten themes were identified presenting their experiences with primary care and described quality care as listening and giving attention to what people with chronic conditions want, to what they strive for, and above all to promote their autonomy in a context wherein they are supported by a team of formal caregivers, family and friends. CONCLUSION: To meet the PCDs' needs, self-management should be addressed in an interprofessional environment in which the PCD is an important partner. The findings may facilitate a shift to encourage PCDs in their strengths by enabling them to share their personal goals and by working towards meaningful activities in team collaboration. RELEVANCE TO CLINICAL PRACTICE: Three strategies-self-management support, goal-oriented care, and interprofessional collaboration-have been suggested to improve the PCDs' primary care experiences. These strategies could guide nursing practice in using more and improve high-quality nursing care.

Centralisation of oesophageal cancer services: experiences and outcomes of the first year of implementation at a Belgian non-academic teachinghospital.

INTRODUCTION: Oesophageal surgery recently became centralised in Belgium. This study aims to evaluate surgical outcomes and service delivered one year after implementation of centralisation. PATIENTS AND METHODS: All patients undergoing an oesophagectomy between the start of the centralisation; 1st of June 2019 and 31st of May 2020, were included from a prospectively maintained database. RESULTS: 53 patients (41 male, 12 female) underwent an oesophagectomy during the study period. Most oesophagectomies were performed through an open left thoracoabdominal approach (64.2%), 30.2% via a minimally invasive approach and hybrid approaches were carried out in 5.7% of patients. In this study population, the 30 day mortality rate was 0% and the 90 day mortality rate was 3.8%, equating to 2 deaths. The overall 30 day readmission rate was 7.5%. Clinically significant anastomotic leaks occurred in 4 patients, (7.5%). Pneumonia and atrial fibrillation were the most frequent complications, both having a prevalence of 32.1%. The median length of stay was 11 days (IQR 9.5-14.5). CONCLUSION: The results from our centre are comparable to those from international registers which demonstrate that centralisation of complex cancer services can be safely implemented.

Evaluating the impact of COVID-19 countermeasures on alcohol consumption through wastewater-based epidemiology: A case study in Belgium.

Wastewater-based epidemiology (WBE) is a complementary approach to monitor alcohol consumption in the general population. This method measures concentrations of xenobiotic biomarkers (e.g., ethyl sulphate) in influent wastewater (IWW) and converts these to population-normalized mass loads (PNML, in g/day/1000 inhabitants) by multiplying with the flow rate and dividing by the catchment population. The aims of this case study were to: (i) investigate temporal trends in alcohol use during the COVID-19 pandemic; and (ii) measure the effect of policy measures on alcohol consumption. Daily 24-h composite IWW samples (n = 735) were collected in the wastewater treatment plant of the university city of Leuven (Belgium) starting from September 2019 to September 2021. This is the first study that investigates alcohol use through WBE for a continuous period of two years on a daily basis. Mobile phone data was used to accurately capture population fluxes in the catchment area. Data was evaluated using a time series based statistical framework to graphically and quantitatively assess temporal differences in the measured PNML. Different WBE studies observed temporal changes in alcohol use during the COVID-19 pandemic. In this study, the PNML of ethyl sulphate decreased during the first lockdown phase, potentially indicating that less alcohol was consumed at the Leuven area during home confinement. Contrastingly, alcohol use increased after the re-opening of the catering industry. Additionally, a decrease in alcohol use was observed during the exam periods at the University of Leuven and an increase during the holiday periods. The present study shows the potential of WBE to rapidly assess the impact of some policy measures on alcohol consumption in Belgium. This study also indicates that WBE could be employed as a complementary data source to fill in some of the current knowledge gaps linked to lifestyle behavior.

Scoping review to identify strategies and interventions improving interprofessional collaboration and integration in primary care.

OBJECTIVE: To identify strategies and interventions used to improve interprofessional collaboration and integration (IPCI) in primary care. DESIGN: Scoping review DATA SOURCES: Specific Medical Subject Headings terms were used, and a search strategy was developed for PubMed and afterwards adapted to Medline, Eric and Web of Science. STUDY SELECTION: In the first stage of the selection, two researchers screened the article abstracts to select eligible papers. When decisions conflicted, three other researchers joined the decision-making process. The same strategy was used with full-text screening. Articles were included if they: (1) were in English, (2) described an intervention to improve IPCI in primary care involving at least two different healthcare disciplines, (3) originated from a high-income country, (4) were peer-reviewed and (5) were published between 2001 and 2020. DATA EXTRACTION AND SYNTHESIS: From each paper, eligible data were extracted, and the selected papers were analysed inductively. Studying the main focus of the papers, researchers searched for common patterns in answering the research question and exposing research gaps. The identified themes were discussed and adjusted until a consensus was reached among all authors. RESULTS: The literature search yielded a total of 1816 papers. After removing duplicates, screening titles and abstracts, and performing full-text readings, 34 papers were incorporated in this scoping review. The identified strategies and interventions were inductively categorised under five main themes: (1) Acceptance and team readiness towards collaboration, (2) acting as a team and not as an individual; (3) communication strategies and shared decision making, (4) coordination in primary care and (5) integration of caregivers and their skills and competences. CONCLUSIONS: We identified a mix of strategies and interventions that can function as 'building blocks', for the development of a generic intervention to improve collaboration in different types of primary care settings and organisations.

Incorporating 'reason for use' into the prescribing process of medication: a survey on the opinion of patients in Flanders, Belgium.

BACKGROUND: A longstanding debate exists about including a 'reason for use' on prescriptions for medication. Little is known, however, about patients' opinions on this subject. METHODS: An internet-based questionnaire, consisting mainly of Likert scale questions, was distributed online to the general public in Belgium. Results from 1034 responses were analyzed using descriptive statistics. RESULTS: Opinions from patients toward including a 'reason for use' on medication prescriptions were generally positive. A clear majority of 62% increased to 74% after providing information about the possible link between indication and medication dose. A majority of the participants expressed a positive attitude regardless of the pathology involved, although sexually transmitted diseases were of greatest concern. Other important aspects differentiating the opinion positively was the transmission of this information in an electronic-only form and limiting it to the regular pharmacist excluding further use by third parties such as other pharmacies or insurance companies. Patients using multiple medicines and those frequenting the same pharmacy also had a more favorable opinion about including the reason for use. In addition, analysis of physician and pharmacist questionnaire responses, explicitly excluded from the main analysis, confirmed the known contrasting opinions in these subgroups. CONCLUSIONS: Patients have strong support for transferring information on the 'reason for use' of their prescriptions to their regular pharmacy if this is done in a secure and privacy-conscious way enabling increased patient safety and improved pharmaceutical care.

Opioid prescribing in out-of-hours primary care in Flanders and the Netherlands: A retrospective cross-sectional study.

BACKGROUND: Increased opioid prescribing has raised concern, as the benefits of pain relief not always outweigh the risks. Acute and chronic pain is often treated in a primary care out-of-hours (OOH) setting. This setting may be a driver of opioid use but the extent to which opioids are prescribed OOH is unknown. We aimed to investigate weak and strong opioid prescribing at OOH primary care services (PCS) in Flanders (Northern, Dutch-speaking part of Belgium) and the Netherlands between 2015 and 2019. METHODS: We performed a retrospective cross sectional study using data from routine electronic health records of OOH-PCSs in Flanders and the Netherlands (2015-2019). Our primary outcome was the opioid prescribing rate per 1000 OOH-contacts per year, in total and for strong (morphine, hydromorphone, oxycodone, oxycodone and naloxone, fentanyl, tapentadol, and buprenorphine and weak opioids (codeine combinations and tramadol and combinations) and type of opioids separately. RESULTS: Opioids were prescriped in approximately 2.5% of OOH-contacts in both Flanders and the Netherlands. In Flanders, OOH opioid prescribing went from 2.4% in 2015 to 2.1% in 2017 and then increased to 2.3% in 2019. In the Netherlands, opioid prescribing increased from 1.9% of OOH-contacts in 2015 to 2.4% in 2017 and slightly decreased thereafter to 2.1% of OOH-contacts. In 2019, in Flanders, strong opioids were prescribed in 8% of the OOH-contacts with an opioid prescription. In the Netherlands a strong opioid was prescribed in 57% of these OOH-contacts. Two thirds of strong opioids prescriptions in Flanders OOH were issued for patients over 75, in the Netherlands one third was prescribed to this age group. CONCLUSION: We observed large differences in strong opioid prescribing at OOH-PCSs between Flanders and the Netherlands that are likely to be caused by differences in accessibility of secondary care, and possibly existing opioid prescribing habits. Measures to ensure judicious and evidence-based opioid prescribing need to be tailored to the organisation of the healthcare system.

Temporal monitoring of stimulants during the COVID-19 pandemic in Belgium through the analysis of influent wastewater.

BACKGROUND AND AIMS: Wastewater-based epidemiology (WBE) is a complementary epidemiological data source to monitor stimulant consumption. The aims were to: (i) study intra- and inter-year temporal changes in stimulant use in Belgium during the first wave of the COVID-19 pandemic; and (ii) evaluate the effect of COVID-19 restrictive measures on stimulant consumption. METHODS: The study population corresponded to the catchments of four wastewater treatment plants corresponding with four Belgian cities (i.e., Antwerp-Zuid, Boom, Brussels, Leuven). Daily 24-h composite influent wastewater samples collected over one week in September 2019 and March through June 2020 during the first wave of the COVID-19 pandemic were analyzed for biomarkers of amphetamine, cocaine, methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA). Measured concentrations were converted to population-normalized mass loads by considering the daily flow rate and the catchment population size. Mobile network data was used to accurately capture population movements in the different catchment areas. Temporal changes were assessed with multiple linear regression models, and the effect of the COVID-19 interventions on stimulant consumption were investigated. RESULTS: An increase in amphetamine use was observed in three cities during governmental restrictions, with highest consumption predominantly during lockdown. Similarly, cocaine consumption was higher after the pandemic started, with highest consumption noted during the lockdown period in Boom and Leuven. Consumption of MDMA was similar in Antwerp-Zuid, Brussels and Leuven throughout the entire sampled period. In Boom, the highest consumption was observed during the full lockdown period. CONCLUSIONS: The present study shows the potential of WBE to assess the impact of stringent lockdown measures on stimulant use in Belgium. This paper shows that strong restrictive measures did not have a profound effect on stimulant consumption.

Replacing vaccine paper package inserts: a multi-country questionnaire study on the acceptability of an electronic replacement in different target groups.

BACKGROUND: In the European Union it is mandatory to include paper package leaflets (PPL) with all medicines, including vaccines, to inform the recipient. However, it is difficult to meet the necessity for localized PPLs in each of the 24 official European languages. Replacing PPLs with electronic versions offers many advantages including redistribution across nations, reduced storage space, accessibility by the visually impaired, easily updated information or the addition of video content. We wanted to assess the attitudes of patients (vaccine recipients or their parents) to the potential of replacing PPL with electronic versions. METHODS: We surveyed vaccinees or their parents in four European countries-Belgium, Italy, Bulgaria and France-for their actual use of vaccine PPLs and their opinions about switching to an electronic package leaflet. Our survey was conducted online because of the COVID-19 pandemic and resulted in 2518 responses to a questionnaire targeted at three specific groups with particular information needs: parents of young children, pregnant women and the elderly (≥ 60 years). RESULTS: Our main findings are that currently vaccine PPLs are rarely used and frequently unavailable for the vaccinee. Across the four countries surveyed 55-82% of vaccinees would accept an electronic version, as did 64% when there was an option to request a printout of the leaflet. CONCLUSIONS: We found that switching to electronic versions of vaccine PPLs is an acceptable alternative for the public, potentially increasing the quality and amount of information reaching vaccinees while eliminating some barriers to redistribution of vaccines between countries.

Antibiotic Prescribing Trends in Belgian Out-of-Hours Primary Care during the COVID-19 Pandemic: Observational Study Using Routinely Collected Health Data.

Antibiotic overprescribing is one of the main drivers of the global and growing problem of antibiotic resistance, especially in primary care and for respiratory tract infections (RTIs). RTIs are the most common reason for patients to consult out-of-hours (OOH) primary care. The COVID-19 pandemic has changed the way general practitioners (GPs) work, both during office hours and OOH. In Belgian OOH primary care, remote consultations with the possibility of issuing prescriptions and telephone triage were implemented. We aimed to describe the impact of COVID-19 on GPs' antibiotic prescribing during OOH primary care. In an observational study, using routinely collected health data from GP cooperatives (GPCs) in Flanders, we analyzed GPs' antibiotic prescriptions in 2019 (10 GPCs) and 2020 (20 GPCs) during OOH consultations (telephone and face-to-face). We used autoregressive integrated moving average (ARIMA) modeling to identify any changes after lockdowns were implemented. In total, 388,293 contacts and 268,430 prescriptions were analyzed in detail. The number of antibiotic prescriptions per weekend, per 100,000 population was 11.47 (95% CI: 9.08-13.87) or 42.9% lower after compared to before the implementation of lockdown among all contacts. For antibiotic prescribing per contact, we found a decrease of 12.2 percentage points (95% CI: 10.6-13.7) or 56.5% among all contacts and of 5.3 percentage points (95% CI: 3.7-6.9) or 23.2% for face-to-face contacts only. The decrease in the number of prescriptions was more pronounced for cases with respiratory symptoms that corresponded with symptoms of COVID-19 and for antibiotics that are frequently prescribed for RTIs, such as amoxicillin (a decrease of 64.9%) and amoxicillin/clavulanate (a decrease of 38.1%) but did not appear for others such as nitrofurantoin. The implementation of COVID-19 lockdown measures coincided with an unprecedented drop in the number of antibiotic prescriptions, which can be explained by a decrease in face-to-face patient contacts, as well as a lower number of antibiotics prescriptions per face-to-face patient contact. The decrease was seen for antibiotics used for RTIs but not for nitrofurantoin, the first-choice antibiotic for urinary tract infections.

Overprescribing of Topical Ocular Corticosteroids and Antibiotics in Out-of-Hours Primary Care in Belgium.

Prescribing patterns by primary care physicians concerning ophthalmic problems were studied using the iCAREdata, a database containing information from the out-of-hours care setting in the Flanders region of Belgium. A very high percentage of prescribed ophthalmic medication was topical antibiotics (89.4%) with tobramycin as the most prevalent substance and in clear conflict with the prevailing guidelines. In addition, a very substantial fraction of prescribed medication contained corticosteroids (30.4%). This is a potentially unsafe option within the technical infrastructure of this setting, which limits the diagnostic possibilities concerning viral infections or preexisting glaucoma risk. We conclude that more efforts are required to limit unnecessary and inappropriate prescribing behavior to further promote patient safety.

Out of pocket expenses: effect of fee-waivers on opioid prescribing and dispensing.

INTRODUCTION: Pharmaceutical reimbursement policies should aim for satisfactory health care at reasonable prices and assure treatment adherence while avoiding wasteful pharmaceutical spending. In Belgium, the maximum billing system, also called "Maximum Amount Fixed" system (MAF), ensures that out-of-pocket payments beyond a ceiling are fully reimbursed to guarantee pharmaceutical treatment in vulnerable population groups (e.g. low-income people and chronic patients). Starting from 2015, a policy change occurred and these expenses were waived during the same calendar year once this ceiling was reached instead of reimbursing these expenses in the next fiscal year. Each subsequent fiscal year, out-of-pocket payments were reintroduced in January. METHODS: Longitudinal dispensing trends, from early 2013 to mid-2020, for 13 prevalent reimbursed opioids were investigated. RESULTS: For MAF patients, significant seasonal increases in opioid dispensing reoccurred towards the end of the year. This pattern was absent for non-MAF patients and was only observed after the 2015 policy change. Periodic changes in out-of-pocket expenses, a characteristic of the reimbursement policy in Belgium, clearly influences opioid availability in an already at-risk group. CONCLUSIONS: Out-of-pocket reimbursement policies should be urgently re-evaluated to minimize unnecessary opioid exposure, while preserving the affordability of pain treatment for vulnerable patients.

Current and future perspectives for wastewater-based epidemiology as a monitoring tool for pharmaceutical use.

The medical and societal consequences of the misuse of pharmaceuticals clearly justify the need for comprehensive drug utilization research (DUR). Wastewater-based epidemiology (WBE) employs the analysis of human metabolic excretion products in wastewater to monitor consumption patterns of xenobiotics at the population level. Recently, WBE has demonstrated its potential to evaluate lifestyle factors such as illicit drug, alcohol and tobacco consumption at the population level, in near real-time and with high spatial and temporal resolution. Up until now there have been fewer WBE studies investigating health biomarkers such as pharmaceuticals. WBE publications monitoring the consumption of pharmaceuticals were systematically reviewed from three databases (PubMed, Web of Science and Google Scholar). 64 publications that reported population-normalised mass loads or defined daily doses of pharmaceuticals were selected. We document that WBE could be employed as a complementary information source for DUR. Interest in using WBE approaches for monitoring pharmaceutical use is growing but more foundation research (e.g. compound-specific uncertainties) is required to link WBE data to routine pharmacoepidemiologic information sources and workflows. WBE offers the possibility of i) estimating consumption of pharmaceuticals through the analysis of human metabolic excretion products in wastewater; ii) monitoring spatial and temporal consumption patterns of pharmaceuticals continuously and in near real-time; and iii) triangulating data with other DUR information sources to assess the impacts of strategies or interventions to reduce inappropriate use of pharmaceuticals.
