Outpatient Antipsychotic Use and Severe COVID-19: Avoiding the Impact of Age in a Real-World Data Study.

BACKGROUND: The association between use of antipsychotics and COVID-19 outcomes is inconsistent, which may be linked to use of these drugs in age-related diseases. Furthermore, there is little evidence regarding their effect in the nongeriatric population. We aim to assess the association between antipsychotic use and risk of disease progression and hospitalization due to COVID-19 among the general population, stratifying by age. METHODS: We conducted a population-based, multiple case-control study to assess risk of hospitalization, with cases being patients with a PCR(+) test who required hospitalization and controls being individuals without a PCR(+) test; and risk of progression to hospitalization, with cases being the same as those used in the hospitalization substudy and controls being nonhospitalized PCR(+) patients. We calculated adjusted odds-ratios (aOR) and 95% confidence intervals (CI), both overall and stratified by age. RESULTS: Antipsychotic treatment in patients younger than 65 years was not associated with a higher risk of hospitalization due to COVID-19 (aOR 0.94 [95%CI = 0.69-1.27]) and disease progression among PCR(+) patients (aOR 0.96 [95%CI = 0.70-1.33]). For patients aged 65 years or older, however, there was a significant, increased risk of hospitalization (aOR 1.58 [95% CI = 1.38-1.80]) and disease progression (aOR 1.31 [95% CI = 1.12-1.55]). CONCLUSIONS: The results of our large-scale real-world data study suggest that antipsychotic use is not associated with a greater risk of hospitalization due to COVID-19 and progression to hospitalization among patients younger than 65 years. The effect found in the group aged 65 years or older might be associated with off-label use of antipsychotics.

Dentists' knowledge, attitudes and perceptions of antibiotic prescribing: A systematic review.

OBJECTIVE: This study aims to explore dentists' knowledge, attitudes, and perceptions regarding antibiotic use. METHODS: We conducted a systematic review of dentists' knowledge, attitudes and perceptions regarding antibiotic use, by searching the MEDLINE, EMBASE and Web of Science for all original paper published from January 1990 to July 2023, in accordance with the Preferred Reporting Items for systematic Reviews and Meta-analyses (PRISMA 2020) guidelines. RESULTS: The review included 37 papers, (7 qualitative and 30 quantitative studies). Modifiable factors (knowledge, attitudes) were reported as being associated with antibiotic prescribing by dentists which were cited in 30 of the 37. These attitudes most frequently identified by dentists were: complacency (22/29); lack of trust (16/29); the need to postpone the dental procedure (17/29); and fear (8/29). Gaps in knowledge were also identified (15/29). Only one of the included articles quantified the influence between the reported modifiable factors and antibiotic prescribing. CONCLUSIONS: The review emphasizes that dentists' antibiotic prescribing is predominantly influenced by modifiable factors. This insight informs the potential for targeted interventions to curtail inappropriate antibiotic use, contributing to global efforts in reducing antibiotic resistance. The protocol of this systematic review can be found in PROSPERO under registration no. CRD42021253937.

Knowledge, attitudes, and practice of primary care professionals regarding community activities: a descriptive study.

BACKGROUND: Promoting health via a community approach is one of the most effective strategies for reducing the current incidence of chronic diseases. Primary care (PC), through the implementation of community activities (CA), has the potential to achieve this goal. Yet the implementation of CA at health centers is not standardized and is often thanks only to the voluntariness of health professionals. OBJECTIVE: To ascertain the knowledge, attitudes, and practices of PC professionals regarding the implementation of CA. METHODS: We carried out a cross-sectional study by circulating a self-administered online questionnaire on CA, across the period December 2022 through June 2023 in Galicia (Spain). All health professionals working in the Galician Health Service PC setting were invited to participate. RESULTS: A total of 521 health professionals participated in the study. They included all types of PC health professionals (physicians, general and specialist nurses -midwives, pediatrics, family and community, mental health- and social workers), including residents in training. Only 14.8% and 12.5% of professionals correctly identified CAs and social prescription (SPr) interventions, respectively. Furthermore, 93.9% recognized that the development of CA in health centers was deficient. Despite this, 76.5% showed a good attitude toward participation in CA. CONCLUSIONS: PC professionals find it difficult to identify CA and SPr interventions. Therefore, it is necessary to improve the training of these professionals in the implementation of CA with a view to enhancing population health, reducing the incidence of chronic diseases, and helping lessen the healthcare burden of the health system.

Unmasking vaccine hesitancy and refusal: a deep dive into Anti-vaxxer perspectives on COVID-19 in Spain.

BACKGROUND: At the time of the emergence of COVID-19, denialist and anti-vaccine groups have also emerged and are shaking public confidence in vaccination. METHODS: A qualitative study was conducted using online focus groups. Participants had not received any doses of vaccination against the disease. A total of five focus group sessions were conducted with 28 participants. They were recruited by snowball sampling and by convenience sampling. RESULTS: The two major topics mentioned by the participants were adverse effects and information. The adverse effects described were severe and included sudden death. In the case of information, participants reported: (1) consultation of websites on which scientists posted anti-vaccination content; and (2) distrust. CONCLUSIONS: At a time when anti-vaccine groups pose a major challenge to public health in general, and to COVID-19 vaccination campaigns in particular, this study is a first step towards gaining deeper insight into the factors that lead to COVID-19 vaccine refusal.

The role of traditional NSAIDs and selective COX-2 inhibitors on COVID-19 outcomes: a real-world data study.

The relation between use of nonsteroidal anti-inflammatory drugs (NSAIDs) and severity of COVID-19 has been the subject to debate since the outbreak of the pandemic. Despite speculations about the possible harmful or protective effects, the position currently most supported by the scientific community is that there is no association between use of NSAIDs and COVID-19 outcomes. With the aim of contributing to increase the body of evidence on this issue, we conducted a case-control study using real-world data to investigate the association between prior use of NSAIDs, by active ingredient and type (traditional NSAIDs and selective COX-2 inhibitors), and important COVID-19-related outcomes, including susceptibility, PCR + patient progression, and hospitalisation. Our findings suggest that, in general, the use of traditional NSAIDs is not associated with any adverse COVID-19 outcome. However, we observed a possible association between diclofenac and a higher risk of PCR + patient progression. Our results also suggest that selective COX-2 inhibitors might be related with a reduction in the risk of PCR + patient progression. These results suggest that, with the possible exception of diclofenac, the use of NSAIDs should not be advised against for relief of symptoms in patients with COVID-19. In addition, they support the importance of continue to investigate the treatment potential of selective COX-2 inhibitors in the management of COVID-19, something that could have significant implications for the treatment of this disease and other viral infections.

Impact of prior antihypertensive treatment on COVID-19 outcomes, by active ingredient.

OBJECTIVES: To assess the impact of prior chronic treatment with angiotensin-converting enzyme inhibitors (ACEIs)/ angiotensin-receptor blockers (ARBs), both as a group and by active ingredient, on severity (risk of hospitalization and mortality), progression of and susceptibility to COVID-19. METHODS: We conducted a multiple population-based case-control study in Galicia (north-west Spain). The study data were sourced from medical, administrative and clinical databases. We assessed: (1) risk of hospitalization, by selecting all patients hospitalized due to COVID-19 with PCR + as cases, and a random sample of subjects without a PCR + as controls; (2) COVID-19 mortality risk; (3) risk of disease progression; and (4) susceptibility to SARS-CoV-2, considering all patients with PCR + as cases, and the same subjects used in the previous model as controls. Adjusted odds ratios (aORs) were calculated. RESULTS: ACEIs and ARBs were shown to decrease the risk of hospitalization (aOR = 0.78 [95%CI 0.69-0.89] and aOR = 0.80 [95%CI 0.72-0.90] respectively), risk of mortality (aOR = 0.71 [95%CI 0.52-0.98] and aOR = 0.69 [95%CI 0.52-0.91] respectively), and susceptibility to the virus (aOR = 0.88 [95%CI 0.82-0.94] and aOR = 0.92 [95%CI 0.86-0.97] respectively). By active ingredient: use of enalapril was associated with a significantly lower risk of hospitalization (aOR = 0.72 [95%CI 0.61-0.85]), mortality (aOR = 0.59 [95%CI 0.38-0.92]) and susceptibility to COVID-19 (aOR = 0.86 [95%CI 0.79-0.94]); and use of candesartan was associated with a decreased risk of hospitalization (aOR = 0.76 [95%CI 0.60-0.95]), mortality (aOR = 0.36 [95%CI 0.17-0.75]) and disease progression (aOR = 0.73 [95%CI 0.56-0.95]). CONCLUSION: This large-scale real-world data study suggest that enalapril and candesartan are associated with a considerable reduction in risk of severe COVID19 outcomes.

Outpatient glucocorticoid use and COVID-19 outcomes: a population-based study.

INTRODUCTION: Owing to controversy information surrounds effect of glucocorticoids on the evolution of COVID-19, we evaluate the effects of outpatient glucocorticoid use on the severity and progression of COVID-19 and risk of infection and analyse the effect of window of exposure and dose. METHODS: We conducted a population-based case - control study, involving 4 substudies: (i) Hospitalisation; (ii) Mortality, using subjects hospitalised with a PCR + as cases and subjects without a PCR + as controls; (iii) Progression, including subjects with a PCR + (hospitalised versus non-hospitalised); and (iv) Susceptibility, with all subjects with a PCR + and subjects without a PCR + . Adjusted odds ratios (ORa) and their 95% confidence intervals (95% CI) were calculated. RESULTS: The outpatient glucocorticoid use was associated with an increased risk of hospitalisation (aOR 1.79; 95% CI 1.56-2.05), mortality (aOR 2.30; 95% CI 1.68-3.15), progression (aOR 1.69; 95% CI 1.43-2.00) and susceptibility (aOR 1.29, 95% CI 1.19-1.41). Furthermore, the effects was observed to be greater at higher doses and the closer that drug use approached the outcome date, with an almost fourfold increase in mortality among users in the previous month (aOR 3.85; 95% CI 2.63-5.62). CONCLUSIONS: According to the results of this real-world data study, outpatient glucocorticoid use should be considered in making decisions about intrahospital treatment.

Outpatient atorvastatin use and severe COVID-19 outcomes: A population-based study.

Evidence of the effect of statins on patients with coronavirus disease (2019) COVID-19 is inconsistent. The aim of this study was to evaluate the association between chronic use of statins-both overall and by active ingredient-and severe outcomes of COVID-19 (risk of hospitalization and mortality), progression to severe outcomes, and susceptibility to the virus. We conducted a population-based case-control study with data from electronic records to assess the risk of (1) hospitalization: cases were patients admitted due to COVID-19 and controls were subjects without COVID-19; (2) mortality: cases were hospitalized patients who died due to COVID-19 and controls were subjects without COVID-19; (3) progression: cases were hospitalized COVID-19 subjects and controls were nonhospitalized COVID-19 patients; and (4) susceptibility: cases were patients with COVID-19 (both hospitalized and nonhospitalized) and controls were subjects without COVID-19. We collected data on 2821 hospitalized cases, 26 996 nonhospitalized cases, and 52 318 controls. Chronic use of atorvastatin was associated with a decreased risk of hospitalization (adjusted odds ratios [aOR] = 0.83; 95% confidence interval [CI]: 0.74-0.92) and mortality (aOR = 0.70; 95% CI: 0.53-0.93), attributable in part to a lower risk of susceptibility to the virus (aOR = 0.91; 95% CI: 0.86-0.96). Simvastatin was associated with a reduced risk of mortality (aOR = 0.59; 95% CI: 0.40-0.87). The wide degree of heterogeneity observed in the estimated odds ratios (ORs) of the different statins suggests that there is no class effect. The results of this real-world study suggest that chronic use of atorvastatin (and to a lesser degree, of simvastatin) is associated with a decrease in risk of severe COVID-19 outcomes.

Magnitude and determinants of antibiotic dispensing without prescription in Spain: a simulated patient study.

Objectives: Excessive and inappropriate use of antibiotics increases antimicrobial resistance. The aim of this study was to determine the magnitude and determinants of antibiotic dispensing without prescription in Spain by the simulated patient technique. Methods: A cross-sectional study was conducted with all the pharmacies in a region of north-west Spain (n = 977), between December 2016 and January 2017. Four actors visited the pharmacies simulating a respiratory infection. Four incremental levels of pressure were used to obtain an antibiotic. The education and sex of the person who was dispensing and the area where the pharmacy was located were recorded. The effect of these independent variables on the dispensing of an antibiotic without prescription (1 = yes, 0 = no) was modelled by logistic regression. Results: An antibiotic was obtained in 18.83% (95% CI = 16.5%-21.41%) of the visits. The area influenced the dispensing of antibiotics without a medical prescription, with a greater likelihood of dispensing in rural (OR = 1.79; 95% CI = 1.20-2.68) or semi-rural (OR = 1.66; 95% CI = 1.13-2.44) areas than in urban areas. No association was found with the sex or the training of the person who dispensed the antibiotic. In the pharmacies in urban areas, a lower level of pressure was needed to obtain the antibiotic. Conclusions: This study shows that one-fifth of the pharmacies still dispense antibiotics without prescription, especially under patient pressure. A rural setting has been identified as a risk factor for dispensing without prescription, so it must be taken into account for future interventions.

Lung cancer and residential radon in never-smokers: A pooling study in the Northwest of Spain.

BACKGROUND: Using a pooled case-control study design, including only never-smokers, we have assessed the association of residential radon exposure with the subsequent occurrence of lung cancer. We also investigated whether residential radon poses a different risk specifically for adenocarcinoma. METHODS: We pooled individual data from different case-control studies conducted in recent years in Northwestern Spain which investigated residential radon and lung cancer. All participants were never-smokers. Cases had a confirmed biopsy of primary lung cancer. Hospital controls were selected at pre-surgery units, presenting for non-complex surgical procedures. They were interviewed using a standardized instrument. Residential radon was measured using alpha track detectors at the Galician Radon Laboratory at the University of Santiago de Compostela. RESULTS: A total of 1415 individuals, 523 cases and 892 controls were included. We observed an odds ratio of 1.73 (95%CI: 1.27-2.35) for individuals exposed to ≥ 200 Bq/m3 compared with those exposed to ≤100 Bq/m3. Lung cancer risk for adenocarcinoma was 1.52 (95%CI: 1.14-2.02) using the same categories for radon exposure. CONCLUSIONS: Residential radon is a clear risk factor for lung cancer in never-smokers. Our data suggest that radon exposure is associated with all histological types of lung cancer and also with adenocarcinoma, which is currently the most frequent histological type for this disease.

Determinants of antibiotic dispensing without a medical prescription: a cross-sectional study in the north of Spain.

OBJECTIVES: Antibiotic resistance is a major public health concern and is greatly exacerbated by inappropriate antibiotic use at a community level. The aim of this study was to ascertain which attitudes of community pharmacists were related to inappropriate antibiotic dispensing. METHODS: We conducted a cross-sectional study of community pharmacists in a region situated in northern Spain (n = 393). Personal interviews were conducted using a self-administered questionnaire. The degree of agreement with each item of knowledge and attitude was measured using an unnumbered, horizontal visual analogue scale, with replies being scored from 0 (total disagreement) to 10 (total agreement). The data were analysed using logistic regression. RESULTS: Of the total of 286 pharmacists (72.8%) who completed the questionnaire, 185 (64.7%) acknowledged having undertaken dispensing of antibiotics without a medical prescription (DAwMP). Attitudes such as patient complacency, external responsibility, indifference and insufficient knowledge were shown to be related to DAwMP. In contrast, no association was found with any of the pharmacists' personal or professional traits. CONCLUSIONS: This study confirms that, albeit unlawful, DAwMP is a common practice in Spanish pharmacies. DAwMP was seen to be usually associated with some of the attitudes evaluated.

Impact of prior use of antiplatelets on COVID-19 susceptibility, progression, and severity: a population-based study.

INTRODUCTION AND OBJECTIVES: Hypercoagulability and thromboembolism are processes that arise from severe acute respiratory syndrome coronavirus 2 infection and are responsible for a high degree of coronavirus disease 2019 (COVID-19)-related morbidity and mortality. This study sought to assess the effect of antiplatelet drugs on COVID-19 severity (risk of hospitalization and mortality), susceptibility to severe acute respiratory syndrome coronavirus 2 infection, and progression to severe COVID-19. METHODS: We conducted a population-based case-control study in a northwestern region of Spain in 2020. The study involved 3060 participants with a positive polymerase chain reaction test who were hospitalized, 26 757 participants with a positive polymerase chain reaction test who were not hospitalized, and 56 785 healthy controls. RESULTS: Triflusal seemed to be associated with a significant increase in risk of hospitalization (aOR, 1.97; 95%CI, 1.27-3.04) and susceptibility to infection (OR, 1.45; 95%CI, 1.07-1.96). It also appeared to lead to a nonsignificant increase in the risk of mortality (OR, 2.23; 95%CI, 0.89-5.55) and/or progression to more severe disease stages (OR, 1.42; 95%CI, 0.8-2.51). Aspirin seemed to be associated with a statistically significant decrease in susceptibility to severe acute respiratory syndrome coronavirus 2 infection (OR, 0.92; 95%CI, 0.86-0.98). CONCLUSIONS: Triflusal use appears to increase the risk of susceptibility to COVID-19 infection and an even higher risk of hospitalization, whereas the other antiplatelets could be associated with a reduction in the risk of the various outcomes or have no effect on risk. These findings could support reconsideration of triflusal prescription in COVID-19 pandemic situations.

Community Activities in Primary Care: A Literature Review.

Community health promotion activities are a useful tool for a proactive approach to healthy lifestyles. However, the implementation of these types of activities at health centers is not standardized. The aim of this review was to analyse the characteristics of community activities undertaken in the primary care setting and substantiate available evidence on their health impact. We conducted a bibliographic review until November 15th, 2023 in the TRIPDATABASE, MEDLINE, EMBASE, and DIALNET databases. We included original papers on interventions, community activities, and actions and/or social prescriptions which had been implemented in a Primary Care setting, included a group approach in at least one session, and described some type of evaluation of the intervention applied. Studies targeted at professionals and those without involvement of the primary care team were excluded. The search identified 1912 potential studies. We included a total of 30 studies, comprising 11 randomized clinical trials, 14 quasi-experimental studies, 1 cohort study, and 4 qualitative studies. The issues most frequently addressed in community activities were healthy habits, physical activity, cardiovascular diseases and diabetes. Community activities can improve the physical and psychological environment of their participants, as well as their level of knowledge about the issues addressed. That said, however, implementation of these types of interventions is not uniform. The existence of a professional community-activity liaison officer at health centers, who would help integrate the health system with the community sector, could serve to standardize implementation and maximize the health impact of these types of interventions.

Magnitude and determinants of inappropriate prescribing of antibiotics in dentistry: a nation-wide study.

BACKGROUND: Dentist play an important role in misuse of antibiotics. Identification of the dental activities linked to the misuse of antibiotics is important for improving dentists' prescribing quality. The aim of the study was to quantify the magnitude of inappropriate antibiotic prescribing by dentists in Spain and identify the characteristics, knowledge and attitudes that influence prescribing quality. MATERIAL AND METHODS: We conducted a cross-sectional, questionnaire-based study on dentists in Spain, assessing prescribing quality (dependent variable) on the basis of their responses about the prescription of antibiotics in 14 clinical situations. As the independent variables, we assessed professional characteristics and attitudes (lack of knowledge, fear, complacency, scheduling problems, and economic benefit) measured on a Likert scale. Odds Ratios (OR) (95%CI) were calculated using logistic regression. RESULTS: A total of 878 participants were included in the analysis. Half of all dentists displayed inappropriate antibiotic prescribing habits in more than 28.6% (10/14) of the clinical situations posed (interquartile range 57-79%). Prescribing quality increased when resistance was perceived as a public health problem (OR 0.88, 95% CI: 0.79-0.97), and decreased in response to fear (OR 1.12, 95% CI:1.07-1.18) or the pursuit of economic benefit (OR 1.07, 95% CI 1.01-1.14). Having over 30 years' experience (OR 4.58, 95% CI:1.80-12.48) and/or practising in the field of prosthodontics as opposed to endodontics (OR 2.65, 95% CI:1.26-5.71) were associated with worse prescribing quality. CONCLUSIONS: Antibiotics are the most commonly prescribed drugs in dentistry, and in many cases this prescription is inappropriate. Our findings shows that modifiable factors influence prescribing quality among dentists in Spain. These may be use for designing educational and training programmes for dentists.

Repurposing selective serotonin reuptake inhibitors for severity of COVID-19: A population-based study.

The World Health Organization has proposed that a search be made for alternatives to vaccines for the prevention and treatment of COVID-19, with one such alternative being selective serotonin reuptake inhibitors (SSRIs). This study thus sought to assess: the impact of previous treatment with SSRI antidepressants on the severity of COVID-19 (risk of hospitalisation, admission to an intensive care unit [ICU], and mortality), its influence on susceptibility to SARS-CoV-2 and progression to severe COVID-19. We conducted a population-based multiple case-control study in a region in the north-west of Spain. Data were sourced from electronic health records. Adjusted odds ratios (aORs) and 95%CIs were calculated using multilevel logistic regression. We collected data from a total of 86,602 subjects: 3060 cases PCR+, 26,757 non-hospitalised cases PCR+ and 56,785 controls (without PCR+). Citalopram displayed a statistically significant decrease in the risk of hospitalisation (aOR=0.70; 95% CI 0.49-0.99, p = 0.049) and progression to severe COVID-19 (aOR=0.64; 95% CI 0.43-0.96, p = 0.032). Paroxetine was associated with a statistically significant decrease in risk of mortality (aOR=0.34; 95% CI 0.12 - 0.94, p = 0.039). No class effect was observed for SSRIs overall, nor was any other effect found for the remaining SSRIs. The results of this large-scale, real-world data study indicate that, citalopram, could be a candidate drug for being repurposed as preventive treatment aimed at reducing COVID-19 patients' risk of progressing to severe stages of the disease.

Use of Antidepressants and the Risk of Upper Gastrointestinal Tract Bleeding: A Case-control Study.

PURPOSE: To investigate the association between the use of antidepressants and the risk of upper gastrointestinal tract bleeding (UGIB). METHODS: A Case-control study was conducted in a Brazilian hospital complex. Cases were defined as patients with a diagnosis of UGIB and controls as patients admitted for reasons unrelated to gastrointestinal bleeding, gastric concerns, or complications associated with low-dose aspirin (LDA) or nonsteroidal anti-inflammatory drugs (NSAIDs) use. Sociodemographic and clinical data, comorbidities, drug therapy in use (long-term use and self-medication), and lifestyle habits were recorded through face-to-face interviews. Two groups were defined: use of antidepressants in general and use of antidepressants according to their affinity for serotonin transporters. The presence of synergism between the concomitant use of antidepressants and LDA or NSAIDs on the risk of UGIB was also explored. FINDINGS: A total of 906 participants were recruited (200 in the case group and 706 in the control group). The use of antidepressants was not associated with the risk of UGIB (odds ratio [OR] = 1.503; 95% CI, 0.78-2.88) or the use of antidepressants with high affinity for serotonin receptors (OR = 1.983; 95% CI, 0.81-4.85). An increased risk of UGIB was observed in concomitant users of antidepressants and LDA (OR = 5.489; 95% CI, 1.60-18.81) or NSAIDs (OR = 18.286; 95% CI, 3.18-105.29). Despite the lack of significance, the use of antidepressants appears to be a positive modifier of UGIB risk in LDA and NSAID users. IMPLICATIONS: These findings indicate an increased risk of UGIB in concomitant users of antidepressants and LDA or NSAIDs, suggesting the need to monitor antidepressant users, especially those most likely to develop UGIB. In addition, further studies with larger sample sizes are needed to confirm these findings.

Effect of Previous Anticoagulant Treatment on Risk of COVID-19.

INTRODUCTION: Little is known about the role played by anticoagulants in COVID-19. OBJECTIVE: The aim of this study was to assess the impact of previous anticoagulant treatment on risk of hospitalization due to COVID-19, progression to severe COVID-19 and susceptibility to COVID-19 infection. METHODS: We conducted a multiple population-based case-control study in northwest Spain, in 2020, to assess (1) risk of hospitalization: cases were all patients admitted due to COVID-19 with PCR confirmation, and controls were a random matched sample of subjects without a positive PCR; (2) progression: cases were hospitalized COVID-19 subjects, and controls were all non-hospitalized COVID-19 patients; and (3) susceptibility: cases were patients with a positive PCR (hospitalized and non-hospitalized), and the controls were the same as for the hospitalization model. Adjusted odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using a generalized linear mixed model. RESULTS: The consumption of antivitamin K and direct-acting anticoagulants apparently was not associated with the risk of progression to severe COVID-19 (OR 0.93 [95% CI 0.74-1.17] and OR 1.04 [95% CI 0.79-1.36], respectively). Antivitamin K anticoagulants were associated with a significantly lower risk of hospitalization (OR 0.77 [95% CI 0.64-0.93]), which, in part, can be explained by a decreased risk of susceptibility to infection (OR 0.83 [95% CI 0.74-0.92]). The use of direct-acting anticoagulants was not associated with the risk of hospitalization, although it also seems to decrease susceptibility (OR 0.85 [95% CI 0.74-0.98]). It has also been observed that low-molecular-weight heparins were associated with an increased risk of progression to severe COVID-19 (OR 1.25 [95% CI 1.01-1.55]). CONCLUSION: The results of this study have shown that antivitamin K anticoagulants and direct-acting anticoagulants do not increase the risk of progression to more severe stages. Antivitamin K consumption was associated with a lower risk of hospitalization and susceptibility to infection.

Impact of the COVID-19 Pandemic on Antibiotic Prescribing by Dentists in Galicia, Spain: A Quasi-Experimental Approach.

BACKGROUND: Antibiotic resistance is one of the most pressing public health problems. Health authorities, patients, and health professionals, including dentists, are all involved in its development. COVID-19 pandemic restrictions on dental care may have had repercussions on antibiotic prescribing by dentists. The aim of this study was to assess the impact of the COVID-19 pandemic on antibiotic prescribing by dentists, and to review antibiotic consumption according to the WHO Access, Watch, Reserve classification. We conducted a natural, before-and-after, quasi-experimental study, using antibiotic prescription data covering the period from January 2017 to May 2021. A segmented regression analysis with interrupted time series data was used to analyse the differences between the numbers of defined daily doses (DDD) of antibiotics prescribed monthly. The outcomes showed an immediate significant decrease in overall antibiotic prescribing by primary-care dentists during lockdown, followed by a non-significant upward trend for the next year. This same pattern was, likewise, observed for Access and Watch antibiotics. COVID-19 pandemic restrictions on dental care influenced the prescription of antibiotics. During confinement, an initial decrease was observed, this trend changed when in person consultations were recovered. It might be beneficial to analyse the prescription of antibiotics using the WHO AWaRe classification, in order to monitor their appropriate use.

Understanding Primary Care Physician Vaccination Behaviour: A Systematic Review.

BACKGROUND: Vaccine hesitancy decreases adult vaccination coverage and has been recognized by WHO as a major health threat. Primary care physicians (PCP) play a key role in vaccination by giving vaccine counselling to their patients. The aim of this systematic review is to identify the knowledge, beliefs, attitudes and barriers (KBAB) associated with own vaccination and patient recommendation in primary care physicians. METHODS: MEDLINE/PubMed, EMBASE and Cochrane Library databases were used to search and identify relevant studies based on their title and abstract. In the next step, the full text of each previously selected article was read for eligibility. Articles were selected by two independent reviewers and data extraction was performed using tables. The following information was extracted: methodological characteristics, demographic factors, professional characteristics, and intrinsic or extrinsic factors influencing vaccination or recommendation. RESULTS: Our search yielded 41 eligible papers, data-sources, previous practices, belief in the effectiveness or safety of the vaccine, perceived risk, and trust in health authorities were all shown to be related to own vaccination and patient recommendation. CONCLUSION: Internet is the main source of information for PCP related to vaccine hesitancy. It is therefore essential to increase the presence and access to pro-vaccination content in this area. In addition, involving PCP in the establishment of vaccination recommendations could improve their credibility in the institutions. On the other hand, training in communication skills and establishing reminder systems could reflect higher vaccination coverage among their patients.

A roadmap for the development and evaluation of the eHealthResp online course.

Background: Inappropriate antibiotic use constitutes one of the most concerning public health issues, being one of the main causes of antibiotic resistance. Hence, to tackle this issue, it is important to encourage the development of educational interventions for health practitioners, namely by using digital health tools. This study focuses on the description of the development and validation process of the eHealthResp online course, a web platform directed to physicians and pharmacists, with the overall goal of improving antibiotic use for respiratory tract infections, along with the assessment of its usability. Methods: The eHealthResp platform and the courses, developed with a user-centered design and based on Wordpress and MySQL, were based on a previously developed online course. A questionnaire to assess the usability was distributed among physicians (n = 6) and pharmacists (n = 6). Based on the obtained results, statistical analyses were conducted to calculate the usability score and appraise the design of the online course, as well as to compare the overall scores attributed by both groups. Further qualitative comments provided by the participants have also been analyzed. Results: The eHealthResp contains two online courses directed to physicians and pharmacists aiming to aid in the management of respiratory tract infections.
