Our study aimed to assess latent tuberculosis infection (LTBI) prevalence, screening uptake, adherence to preventive treatment, and their predictors in a large cohort of asylum seekers. We retrospectively analysed data of migrants screened in 2015-2017 at the Migrant's Service in Verona, Italy. Sequential interferon-gamma-release-assay (IGRA) was performed to confirm only tuberculin-skin-test (TST) results ranking from 5 to 14 mm. Among 2,486 asylum seekers, screening adherence was 89.74% and LTBI prevalence was 28.8% (CI95% 27.0;30.5). Predictors of LTBI diagnosis were: male gender (OR 1.62), age 24 years or older (OR 1.47) and African origin (OR 1.78). Therapy completion rate was 69.6% and resulted associated with African origin (OR 1.75) and being older than 24 years (OR 2.89). Sequential IGRA testing, given its expensiveness, could be used to confirm only intermediate TST results, thus enabling further LTBI cases to be detected and avoiding unnecessary preventive treatments.

Immunogenicity against intravitreally administered brolucizumab has been previously described and associated with cases of severe intraocular inflammation, including retinal vasculitis/retinal vascular occlusion (RV/RO). The presence of antidrug antibodies (ADAs) in these patients led to the initial hypothesis that immune complexes could be key mediators. Although the formation of ADAs and immune complexes may be a prerequisite, other factors likely contribute to some patients having RV/RO, whereas the vast majority do not. To identify and characterize the mechanistic drivers underlying the immunogenicity of brolucizumab and the consequence of subsequent ADA-induced immune complex formation, a translational approach was performed to bridge physicochemical characterization, structural modeling, sequence analysis, immunological assays, and a quantitative systems pharmacology model that mimics physiological conditions within the eye. This approach revealed that multiple factors contributed to the increased immunogenic potential of brolucizumab, including a linear epitope shared with bacteria, non-natural surfaces due to the single-chain variable fragment format, and non-native drug species that may form over prolonged time in the eye. Consideration of intraocular drug pharmacology and disease state in a quantitative systems pharmacology model suggested that immune complexes could form at immunologically relevant concentrations modulated by dose intensity. Assays using circulating immune cells from treated patients or treatment-naïve healthy volunteers revealed the capacity of immune complexes to trigger cellular responses such as enhanced antigen presentation, platelet aggregation, endothelial cell activation, and cytokine release. Together, these studies informed a mechanistic understanding of the clinically observed immunogenicity of brolucizumab and associated cases of RV/RO.

International audience; Repurposing drugs as treatments for COVID-19, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has drawn much attention. Beginning with sigma receptor ligands and expanding to other drugs from screening in the field, we became concerned that phospholipidosis was a shared mechanism underlying the antiviral activity of many repurposed drugs. For all of the 23 cationic amphiphilic drugs we tested, including hydroxychloroquine, azithromycin, amiodarone, and four others already in clinical trials, phospholipidosis was monotonically correlated with antiviral efficacy. Conversely, drugs active against the same targets that did not induce phospholipidosis were not antiviral. Phospholipidosis depends on the physicochemical properties of drugs and does not reflect specific target-based activities—rather, it may be considered a toxic confound in early drug discovery. Early detection of phospholipidosis could eliminate these artifacts, enabling a focus on molecules with therapeutic potential.

The possibility to control luminescence properties of purely organic emitting salts is receiving an ever-growing interest. A full understanding of the manifold effects of counterions on the photophysical properties of charged luminophors deserves thorough investigation. Here, we disclose the impact of different anions, i.e. triflate, iodide and nitrate, on the multiple emissions of a new class of ionic luminophors, based on 1,3-dimethyl-2-(p-tolyl)-1H-benzo[d]imidazol-3-ium, 1. The specific ion-pairing plays a key role in the emissive properties of solids, depending on both the electronegativity of the anion and its distance from the cation. Three main effects emerge from strong ion-pairing: (i) fluorescence quenching, (ii) phosphorescence enhancement and iii) efficient direct population of the triplet-state. As a result, a weak interaction (1-OTf) guarantees intense fluorescence (QY > 50%), while a strong pairing (1-NO3·0.5EtOH and 1-I·0.5CH2Cl2) promotes molecular room temperature phosphorescence (RTP) enhancement. The anion-controlling strategy also enables long-lasting RTP (288 ms) in 1-OTf and ultrabright phosphorescence (QY > 70%) in 1-NO3·0.5EtOH, under direct triplet-excitation at 350 nm.

In January 2020, Chinese health authorities identified a novel coronavirus strain never before isolated in humans. It quickly spread across the world, and was eventually declared a pandemic, leading to about 310 million confirmed cases and to 5,497,113 deaths (data as of 11 January 2022). Influenza viruses affect millions of people during cold seasons, with high impacts, in terms of mortality and morbidity. Patients with comorbidities are at a higher risk of acquiring severe problems due to COVID-19 and the flu—infections that could impact their underlying clinical conditions. In the present study, knowledge, attitudes, and opinions of the general population regarding COVID-19 and influenza immunization were evaluated. A multicenter, web-based, cross-sectional study was conducted between 10 February and 12 July 2020, during the first wave of SARS-CoV-2 infections among the general population in Italy. A sample of 4116 questionnaires was collected at the end of the study period. Overall, 17.5% of respondents stated that it was unlikely that they would accept a future COVID-19 vaccine (n = 720). Reasons behind vaccine refusal/indecision were mainly a lack of trust in the vaccine (41.1%), the fear of side effects (23.4%), or a lack of perception of susceptibility to the disease (17.1%). More than 50% (53.8%; n = 2214) of the sample participants were willing to receive flu vaccinations in the forthcoming vaccination campaign, but only 28.2% of cases had received it at least once in the previous five seasons. A higher knowledge score about SARS-CoV-2/COVID-19 and at least one flu vaccination during previous influenza seasons were significantly associated with the intention to be vaccinated against COVID-19 and influenza. The continuous study of factors, determining vaccination acceptance and hesitancy, is fundamental in the current context, in regard to improve vaccination confidence and adherence rates against vaccine preventable diseases.

The Safety Attitude Questionnaire (SAQ) and Manchester Patient Safety Framework (MaPSaF) are known as effective tools to assess patient safety culture and climate and develop targeted strategies. However, they are seldom applied in an integrated way. The aim of this study was to conduct an implementation project through a novel use of both instruments to gain unique insights. The Italian version of MaPSaF and SAQ were administered to 1,759 healthcare workers from three Italian hospitals (response rate: MaPSaF 70.5%, SAQ 61.6%). MaPSaF evaluation proved an overall bureaucratic level of patient safety culture. SAQ scores showed a predominance of neutral scores (75.99%). The dimension perception of management gained the lowest mean score (53.32), while Stress recognition obtained the highest (75.17). Safety climate perception differed significantly among groups: working in a small hospital, in a medical department, and being a physician were associated with the most positive results. The majority (67.1%) of responders to both MaPSaF and SAQ considered the two instruments as providing with different and complementary information. Overall, results showed that an integrated approach in the evaluation of an organisation's safety culture may result useful for an in-depth analysis of the criticalities and the adoption of appropriate improvement strategies.

Gene and compound functions are often interrogated by perturbation. However, we have limited methods to capture associated phenotypes in an unbiased and holistic manner. Here, we describe Fluopack screening as a novel platform enabling the profiling of subcellular phenotypes associated with perturbation. Our approach leverages imaging of a panel of fluorescent chemical probes to survey cellular processes in an unbiased and high throughput fashion. Segmentation-free, whole image analysis applied to Fluopack images identifies probes revealing distinct phenotypes upon perturbation, thereby informing on the function and mechanism of action of perturbagens. This chemical biology approach allows to interrogate phenotypes that tend to be overlooked by other methods, such as lipid trafficking and ion concentration inside the cell. Fluopack screening is a powerful approach to study orphan protein function, as exemplified by the characterization of TMEM41B as novel regulator of lipid mobilization.

Background Travellers’ risk perception is a key component of travel risk assessment because it influences the adequate implementation of safety precautions. The aims of this study are to validate a tool to analyse travellers’ risk perception to identify which factors can influence it and how it changes upon return. Methods The Traveller’s Risk Perception (TRiP) questionnaire was developed and administered to outpatients before and after travel in three travel clinics. A principal component analysis (PCA) was performed to validate the questionnaire and multivariate regression analysis was used to evaluate the effect of travellers’ characteristics on the risk scores. Results A total of 1020 travellers completed the questionnaire. PCA identified two latent factors: ‘generic-disseminated risks’ and ‘specific-circumstantial risks’. Cronbach’s α was acceptable (0.76 and 0.70, respectively). The ‘generic-disseminated risks’ dimension scored higher than the ‘specific-circumstantial risks’ (p Conclusions The TRiP questionnaire is a valid and reliable tool for rating travellers’ perceptions. Staff in travel clinics should be trained to systematically assess travellers’ risk perception in order to tailor the consultation according to specific information needs.

Given the automatization of care and rationing of time and staff due to economic imperatives, often resulting in dehumanized care, the concept of ‘humanization of care’ has been increasingly discussed in the scientific literature. However, it is still an indistinct concept, lacking well-defined dimensions and to date no literature review has tried to capture it. The objectives of this systematic review were to identify the key elements of humanization of care by investigating stakeholders’ (patients, patients’ caregivers, healthcare providers) perspectives and to assess barriers and strategies for its implementation. We carried out a systematic search of five electronic databases up to December 2017 as well as examining additional sources (e.g., gray literature). Search terms included “humanization/humanisation of care” and “dehumanization/dehumanisation of care”. We conducted a thematic synthesis of the extracted study findings to identify descriptive themes and produce key elements. Of 1327 records retrieved, 14 full-text articles were included in the review. Three main areas (relational, organizational, structural) and 30 key elements (e.g., relationship bonding, holistic approach, adequate working conditions) emerged. Several barriers to implementation of humanization of care exist in all areas. Our systematic review and synthesis contributes to a deeper understanding of the concept of humanization of care. The proposed key elements are expected to serve as preliminary guidance for healthcare institutions aiming to overcome challenges in various forms and achieve humanized and efficient care. Future studies need to fully examine specific practices of humanized care and test quantitatively their effectiveness by examining psychosocial and health outcomes.

First, based on analysis of some—mostly late—Latin texts that positively reflect actual oral delivery, I present some remarks on structure and frequency of Verb-Phrases ‘auxiliary+infinitive’ as arguable markers of ‘orality’ in Latin. Second, I examine the occurrence of these Verb-Phrases in some works by Ambrose of Milan and show that, on the one hand, the investigation of Verb-Phrases might support the view that the De sacramentis and Explanatio symboli are unrevised catecheses, but, on the other hand, it is of no help in the conjecture of the degree of elaboration undergone by those works that, stemming from an oral homiletic delivery, were later revised in view of publication.

ObjectivesDespite growing interest in the second-victim phenomenon and greater awareness of its consequences, there has not been a meta-analysis quantifying the negative impact of adverse events on providers involved in adverse events. This study systematically reviewed the types and prevalence of p

Given the negative impact of adverse events on the wellbeing of healthcare providers, easy access to psychological support is crucial. We aimed to describe the types of support resources available in healthcare organizations, their benefits for second victims, peer supporters’ experiences, and implementation challenges. We also explored how these resources incorporate aspects of Safety I and Safety II. We searched six databases up to 19 December 2019 and additional literature, including weekly search alerts until 21 January 2021. Two reviewers independently performed all methodological steps (search, selection, quality assessment, data extraction, formal narrative synthesis). The 16 included studies described 12 second victim support resources, implemented between 2006 and 2017. Preliminary data indicated beneficial effects not only for the affected staff but also for the peer responders who considered their role to be challenging but gratifying. Challenges during program implementation included persistent blame culture, limited awareness of program availability, and lack of financial resources. Common goals of the support programs (e.g., fostering coping strategies, promoting individual resilience) are consistent with Safety II and may promote system resilience. Investing in second victim support structures should be a top priority for healthcare institutions adopting a systemic approach to safety and striving for just culture.

Repurposing drugs as treatments for COVID-19 has drawn much attention. A common strategy has been to screen for established drugs, typically developed for other indications, that are antiviral in cells or organisms. Intriguingly, most of the drugs that have emerged from these campaigns, though diverse in structure, share a common physical property: cationic amphiphilicity. Provoked by the similarity of these repurposed drugs to those inducing phospholipidosis, a well-known drug side effect, we investigated phospholipidosis as a mechanism for antiviral activity. We tested 23 cationic amphiphilic drugs—including those from phenotypic screens and others that we ourselves had found—for induction of phospholipidosis in cell culture. We found that most of the repurposed drugs, which included hydroxychloroquine, azithromycin, amiodarone, and four others that have already progressed to clinical trials, induced phospholipidosis in the same concentration range as their antiviral activity; indeed, there was a strong monotonic correlation between antiviral efficacy and the magnitude of the phospholipidosis. Conversely, drugs active against the same targets that did not induce phospholipidosis were not antiviral. Phospholipidosis depends on the gross physical properties of drugs, and does not reflect specific target-based activities, rather it may be considered a confound in early drug discovery. Understanding its role in infection, and detecting its effects rapidly, will allow the community to better distinguish between drugs and lead compounds that more directly impact COVID-19 from the large proportion of molecules that manifest this confounding effect, saving much time, effort and cost., One Sentence Summary: Drug-induced phospholipidosis is a single mechanism that may explain the in vitro efficacy of a wide-variety of therapeutics repurposed for COVID-19.

In light of the current coronavirus disease 2019 (COVID-19) pandemic and potential future infectious disease outbreaks, a comprehensive understanding of the negative effects of epidemics and pandemics on healthcare workers’ mental health could inform appropriate support interventions. Thus, we aimed to synthesize and quantify the psychological and psychosomatic symptoms among frontline medical staff. We searched four databases up to March 19, 2020 and additional literature, with daily search alerts set up until October 26, 2020. Studies reporting psychological and/or psychosomatic symptoms of healthcare workers caring for patients with severe acute respiratory syndrome, H1N1, Ebola, Middle East respiratory syndrome, or COVID-19 were eligible for inclusion. Two reviewers independently conducted the search, study selection, quality appraisal, data extraction, and synthesis and involved a third reviewer in case of disagreement. We used random effects modeling to estimate the overall prevalence rates of psychological/psychosomatic symptoms and the I2 statistic. We included 86 studies, reporting data from 75,991 participants. Frontline staff showed a wide range of symptoms, including concern about transmitting the virus to the family (60.39%, 95% CI 42.53–76.96), perceived stress (56.77%, 95% CI 34.21–77.95), concerns about own health (45.97%, 95% CI 31.08–61.23), sleeping difficulties (39.88%, 95% CI 27.70–52.72), burnout (31.81%, 95% CI 13.32–53.89), symptoms of depression (25.72%, 95% CI 18.34–33.86), symptoms of anxiety (25.36%, 95% CI 17.90–33.64), symptoms of posttraumatic stress disorder (24.51%, 95% CI 18.16–31.46), mental health issues (23.11%, 95% CI 15.98–31.10), and symptoms of somatization (14.68%, 95% CI 10.67–19.18). We found consistent evidence for the pervasive and profound impact of large-scale outbreaks on the mental health of frontline healthcare workers. As the CO­VID-19 crisis continues to unfold, guaranteeing easy access to support structures for the entire healthcare workforce is vitally important.

Thanks to the spread of internet technologies, there has recently been a significant upsurge of innovative forms of human cooperation. In an ecosystem characterized by unsteadiness and parceled relations, crowdfunding has quickly become one of the most popular expression of the new wave of the sharing economy philosophies. Although it is undeniable that the success of crowdfunding has increased during a dramatic financial period, characterized by a wide-ranging credit crunch, we can't interpret this phenomenon just as a fade or as a side effect of the economic crisis. However, through a multidisciplinary approach of analysis and through a qualitative explorative research it will be possible to observe what type of solidarity this system is currently promoting.

BACKGROUND During the COVID-19 pandemic, swab tests proved to be effective in containing the infection and served as a means for early diagnosis and contact tracing. However, little evidence exists regarding the correct timing for the execution of the swab test, especially for asymptomatic individuals and health care workers. OBJECTIVE The objective of this study was to analyze changes in the positive findings over time in individual SARS-CoV-2 swab tests during a health surveillance program. METHODS The study was conducted with 2071 health care workers at the University Hospital of Verona, with a known date of close contact with a patient with COVID-19, between February 29 and April 17, 2020. The health care workers underwent a health surveillance program with repeated swab tests to track their virological status. A generalized additive mixed model was used to investigate how the probability of a positive test result changes over time since the last known date of close contact, in an overall sample of individuals who tested positive for COVID-19 and in a subset of individuals with an initial negative swab test finding before being proven positive, to assess different surveillance time intervals. RESULTS Among the 2071 health care workers in this study, 191 (9.2%) tested positive for COVID-19, and 103 (54%) were asymptomatic with no differences based on sex or age. Among 49 (25.7%) cases, the initial swab test yielded negative findings after close contact with a patient with COVID-19. Sex, age, symptoms, and the time of sampling were not different between individuals with an initial negative swab test finding and those who initially tested positive after close contact. In the overall sample, the estimated probability of testing positive was 0.74 on day 1 after close contact, which increased to 0.77 between days 5 and 8. In the 3 different scenarios for scheduled repeated testing intervals (3, 5, and 7 days) in the subgroup of individuals with an initially negative swab test finding, the probability peaked on the sixth, ninth and tenth, and 13th and 14th days, respectively. CONCLUSIONS Swab tests can initially yield false-negative outcomes. The probability of testing positive increases from day 1, peaking between days 5 and 8 after close contact with a patient with COVID-19. Early testing, especially in this final time window, is recommended together with a health surveillance program scheduled in close intervals.

Background: Although preventive strategies have been proposed against catheter-associated urinary tract infections (CAUTIs) in intensive care units (ICUs), more efforts are needed to control the incidence rate. Aim: To distinguish patients according to their characteristics at ICU admission, and to identify clusters of patients at higher risk for CAUTIs. Methods: A two-step cluster analysis was conducted on 9656 patients from the Italian Nosocomial Infections Surveillance in Intensive Care Units project. Findings: Three clusters of patients were identified. Type of admission, patient origin and administration of antibiotics had the greatest weight on the clustering model. Cluster 1 comprised more patients with a medical type of ICU admission who came from the community. Cluster 2 comprised patients who were more likely to come from other wards/hospitals, and to report administration of antibiotics 48 h before or after ICU admission. Cluster 3 was similar to Cluster 2 but was characterized by a lower percentage of patients with administration of antibiotics 48 h before or after ICU admission. Patients in Clusters 1 and 2 had a longer duration of urinary catheterization [median 7 days, interquartile range (IQR) 12 days for Cluster 1; median 7 days, IQR 11 days for Cluster 2] than patients in Cluster 3 (median 6 days, IQR 8 days; P

The psychological impact of the Covid 19 pandemic on cancer patients, a population at higher risk of fatal consequences if infected, has been only rarely evaluated. This study was conducted at the Departments of Oncology of four hospitals located in the Verona area in Italy to investigate the psychological consequences of the pandemic on cancer patients under active anticancer treatments. A 13-item ad hoc questionnaire to evaluate the psychological status of patients before and during the pandemic was administered to 474 consecutive subjects in the time frame between April 27th and June 7th 2020. Among the 13 questions, 7 were considered appropriate to elaborate an Emotional Vulnerability Index (EVI) that allows to separate the population in two groups (low versus high emotional vulnerability) according to observed median values. During the emergency period, the feeling of high vulnerability was found in 246 patients (53%) and was significantly associated with the following clinical variables: female gender, being under chemotherapy treatment, age ≤ 65 years. Compared to the pre-pandemic phase, the feeling of vulnerability was increased in 41 patients (9%), remained stably high in 196 (42%) and, surprisingly, was reduced in 10 patients (2%). Overall, in a population characterized by an high level of emotional vulnerability the pandemic had a marginal impact and only a small proportion of patients reported an increase of their emotional vulnerability.

Objectives The COVID-19 pandemic is putting a huge strain on the provision and continuity of care. The length of sickness absence of the healthcare workers as a result of SARS-CoV-2 infection plays a pivotal role in hospital staff management. Therefore, the aim of this study was to explore the timing of COVID-19 recovery and viral clearance, and its predictive factors, in a large sample of healthcare workers. Study design Retrospective cohort study. Methods The analysis was conducted on data collected during the hospital health surveillance programme for healthcare staff at the University Hospital of Verona; healthcare workers were tested for SARS-CoV-2 through RT-PCR with oro-nasopharyngeal swab samples. The health surveillance programme targeted healthcare workers who either had close contact with SARS-CoV-2 infected patients or were tested as part of the screening-based strategy implemented according to national and regional requirements. Recovery time was estimated from the first positive swab to two consecutive negative swabs, collected 24 hours apart, using survival analysis for both right-censored and interval-censored data. Cox proportional hazard was used for multivariate analysis. Results During the health surveillance programme, 6455 healthcare workers were tested for SARS-CoV-2 and 248 (3.8%, 95% confidence interval [CI] 3.4–4.3) reported positive results; among those who tested positive, 49% were asymptomatic, with a median age of 39.8 years, which is significantly younger than symptomatic healthcare workers (48.2 years, p < 0.001). Screening tests as part of the health surveillance programme identified 31 (12.5%) of the positive cases. Median recovery time was 24 days (95% CI 23–26) and 21.5 days (95% CI 15.5–30.5) in right- and interval-censoring analysis, respectively, with no association with age, sex or presence of symptoms. Overall, 63% of participants required >20 days to test negative on two consecutive swabs. Hospitalised healthcare workers (4.8%) were older and had a significantly longer recovery time compared with non-hospitalised healthcare workers in both analyses (33.5 vs 24 days, p = 0.005). Conclusions Recovery from COVID-19 and viral clearance may take a long time, especially in individuals who are hospitalised. To detect asymptomatic cases, screening programmes for healthcare workers is recommended.

Identifying patients at higher risk of healthcare-associated infections (HAIs) in intensive care units (ICUs) represents a major challenge for public health. Machine learning could improve patient risk stratification and lead to targeted infection prevention and control interventions.To evaluate the performance of the Simplified Acute Physiology Score (SAPS) II for HAI risk prediction in ICUs, using both traditional statistical and machine learning approaches.Data for 7827 patients from the 'Italian Nosocomial Infections Surveillance in Intensive Care Units' project were used in this study. The Support Vector Machines (SVM) algorithm was applied to classify patients according to sex, patient origin, non-surgical treatment for acute coronary disease, surgical intervention, SAPS II at admission, presence of invasive devices, trauma, impaired immunity, and antibiotic therapy in 48 h preceding ICU admission.The performance of SAPS II for predicting HAI risk provides a receiver operating characteristic curve with an area under the curve of 0.612 (P0.001) and accuracy of 56%. Considering SAPS II along with other characteristics at ICU admission, the SVM classifier was found to have accuracy of 88% and an AUC of 0.90 (P0.001) for the test set. The predictive ability was lower when considering the same SVM model but with the SAPS II variable removed (accuracy 78%, AUC 0.66).This study suggested that the SVM model is a useful tool for early prediction of patients at higher risk of HAIs at ICU admission.

Italy presented the first largest COVID-19 outbreak outside of China. Veneto currently ranks fourth among the Italian regions for COVID-19 confirmed cases (~19,000). This study presents health surveillance data for SARS-CoV-2 in 6100 health workers (HW) employed in a large public hospital. Workers underwent oropharyngeal and nasopharyngeal swabs, with a total of 5942 participants (97.5% of the population). A total of 11,890 specimens were tested for SARS-CoV-2 infection using PCR, identifying the viral genes E, RdRP, and N. Positive tests were returned for 238 workers (cumulative incidence of 4.0%, similar in both COVID and nonCOVID units). SARS-CoV-2 risk was not affected by gender, age, or job type, whereas work setting and occupation were both predictors of infection. The risk was higher in medical wards (OR 2.7, 95% CI 1.9&ndash, 3.9) and health services (OR 4.3, 95% CI 2.4&ndash, 7.6), and lower in surgical wards and administration areas. To our knowledge, this study represents the largest available HW case list swab-tested for SARS-CoV-2, covering almost the total workforce. Mass screening enabled the isolation of HW, improved risk assessment, allowed for close contacts of and infected HW to return to work, provided evidence of SARS-CoV-2 diffusion, and presented solid ground to prevent nosocomial SARS-CoV-2 infections. The ongoing concurrent sero-epidemiological study aims to enable the improvement of health surveillance to maintain the safety of HWs and the communities they serve.

Objectives Despite the critical need to understand the diverse responses by second victims to adverse events, there has not been a meta-analysis examining coping by second victims. We aimed to analyze the coping strategies applied by second victims in the aftermath of adverse events. Methods We performed a systematic search of nine electronic databases up to October 2018 and screened additional sources, such as gray databases. Two independent reviewers conducted the search, selection process, quality appraisal, data extraction, and synthesis. In case of dissent, a third reviewer was involved to reach consensus. Quantitative studies of the frequency with which coping strategies were applied by second victims were eligible for inclusion. We calculated the overall frequency of coping strategies and I statistic using random effects modeling. Results Of 10,705 records retrieved, 111 full-text articles were assessed for eligibility and 14 studies eventually included. The five most frequent coping strategies were Changing work attitude (89%, 95% confidence interval [CI] = 80-94), Following policies and guidelines more accurately and closely (89%, 95% CI = 54-98), Paying more attention to detail (89%, 95% CI = 78-94) (task oriented), Problem-solving/concrete action plan (77%, 95% CI = 59-89) (task oriented), and Criticizing or lecturing oneself (74%, 95% CI = 47-90) (emotion oriented). Conclusions Second victims frequently used task- and emotion-oriented coping strategies and, to a lesser degree, avoidance-oriented strategies. To better support second victims and ensure patient safety, coping strategies should be evaluated considering the positive and negative effects on the clinician's personal and professional well-being, relationships with patients, and the quality and safety of healthcare.
