Background: COVID-19 is a worldwide public health concern. Disruptions in the drug market are expected and shortages might worsen. Community pharmacies can contribute to early identification and report of medicines' supply and demand issues. Objective: The aim of this study is to characterize the impact of the COVID-19 outbreak on outpatient medicines' sales and shortages. Methods: A retrospective, time-trend analysis of medicine sales, shortages and laboratory-confirmed COVID-19 cases was performed from February 1st to April 30th, 2020, and its homologous period (regarding sales only). A detailed analysis of 6 pharmaceutical substances was performed. All data were subjected to rescaling using the min-max normalization method, in order to become comparable. Data analysis was performed using Microsoft® Excel. Results: The pandemic resulted in an increase in medicines' demand and reported shortages during the early stage of the outbreak. The maximum proportion of medicine sales was registered on March 13th, 2020, 4 days after the WHO declared COVID-19 a pandemic. By the end of March, sales have already dropped to proportions similar to those of 2019. The maximum proportion of drug shortages was reached about one week after the sales peak and by the end of the study period were below those recorded in the pre-COVID-19 period. The analyzed drugs were paracetamol, ascorbic acid, dapagliflozin plus metformin, rosuvastatin plus ezetimibe, formoterol, and hydroxychloroquine, as these pharmaceutical substances registered the highest growth rate in sales and shortages when compared to the same period in the previous year. Hydroxychloroquine showed the most different pattern trends on sales and shortages of these medicines. Conclusions: Pharmacies can provide timely and real-world data regarding sales and shortages. The adopted measures to guarantee the continuous supply of the medicine market seem to have worked. The long-term impacts of this pandemic are unknown and should continue to be closely monitored.

Background Deprescribing can reduce the use of inappropriate or unnecessary medication; however, the economic value of such interventions is uncertain. Objective This study seeks to identify and synthetise the economic evidence of deprescribing interventions among community-dwelling older adults. Methods Full economic evaluation studies of deprescribing interventions, conducted in the community or primary care settings, in community-dwelling adults aged ≥ 65 years were systematically reviewed. MEDLINE, EconLit, Scopus, Web of Science, CEA-TUFTS, CRD York and Google Scholar databases were searched from inception to February 2021. Two researchers independently screened all retrieved articles according to inclusion and exclusion criteria. The main outcome was the economic impact of the intervention from any perspective, converted into 2019 US Dollars. The World Health Organization threshold of 1 gross domestic product per capita was used to define cost effectiveness. Studies were appraised for methodological quality using the extended Consensus on Health Economics Criteria checklist. Results Of 6154 articles identified by the search strategy, 14 papers assessing 13 different interventions were included. Most deprescribing interventions included some type of medication review with or without a supportive educational component (n = 11, 85%), and in general were delivered within a pharmacist-physician care collaboration. Settings included community pharmacies, primary care/outpatient clinics and patients' homes. All economic evaluations were conducted within a time horizon varying from 2 to 12 months with outcomes in most of the studies derived from a single clinical trial. Main health outcomes were reported in terms of quality-adjusted life-years, prevented number of falls and the medication appropriateness index. Cost effectiveness ranged from dominant to an incremental cost-effectiveness ratio of $112,932 per quality-adjusted life-year, a value above the country's World Health Organization threshold. Overall, 85% of the interventions were cost saving, dominated usual care or were cost effective considering 1 gross domestic product per capita. Nine studies scored > 80% (good) and two scored ≤ 50% (low) on critical quality appraisal. Conclusions There is a growing interest in economic evaluations of deprescribing interventions focused on communitydwelling older adults. Although results varied across setting, time horizon and intervention, most were cost effective according to the World Health Organization threshold. Deprescribing interventions are promising from an economic viewpoint, but more studies are needed.

Background In 2017, ostomy patients gained access to ostomy products in community pharmacies that are fully reimbursed by the Portuguese National Health Service. This impacted the daily lives of people with ostomy and opened a new market of products and services for pharmacies. However, little is known about the sociodemographic and clinical profile of ostomy patients. This study aims to characterize people with ostomy and their caregivers, evaluate access and satisfaction with the pharmacy and explore participants’ expectations regarding services and counselling. Methods This was an observational, cross-sectional, multicentre study involving pharmacy users who acquired ostomy products in Portuguese community pharmacies. Data were collected through a confidential self-report questionnaire between June and August 2019. Results Approximately 56% of the participants were ostomy patients, of whom 65.9% were men. The average age of participating ostomy patients was 65.5 years old (SD = 12.9), and near 80% were retired/pensioners. Caregivers were mostly women (81.7%). More than half of the caregivers were employed and acquired products for a direct family member. Three in every four surgical interventions were consequences of cancer. Intestinal ostomy was the most common intervention (78.3%). More than 93% were satisfied with the acquisition of ostomy products at the pharmacy. Approximately 48.2% of ostomy patients received care from a specialized nurse. Conclusion This study describes the profile of people with ostomy and their caregivers who attend community pharmacies in Portugal. Participants’ perceptions of the utility of different proposed services and pharmacist knowledge, as well as the low coverage of ostomy nursing care, highlight the opportunity for an extended role of pharmacists among this group.
