RESUMO

INTRODUCTION: Although healthcare workers (HCWs) have reported mental health problems since the beginning of the COVID-19 pandemic, they rarely use psychological support. Here, we described the use of psychological support among HCWs in Spain over the 2-year period following the initial pandemic outbreak and explore its association with workplace- and COVID-19-related factors measured at baseline, in 2020. MATERIALS AND METHODS: We conducted a longitudinal study on HCWs working in Spain. We used an online survey to collect information on sociodemographic characteristics, depressive symptoms, workplace- and COVID-19-related variables, and the use of psychological support at three time points (2020, 2021, and 2022). Data was available for 296, 294, and 251 respondents, respectively at time points 1, 2, and 3. RESULTS: Participants had a median age of 43 years and were mostly females (n = 242, 82%). The percentage of HCWs using psychological support increased from 15% in 2020 to 23% in 2022. Roughly one in four HCWs who did not use psychological support reported symptoms compatible with major depressive disorder at follow up. Baseline predictors of psychological support were having to make decisions about patients' prioritisation (OR 5.59, 95% CI 2.47, 12.63) and probable depression (wave 2: OR 1.12, 95% CI 1.06, 1.19; wave 3: OR 1.10, 95% CI 1.04, 1.16). CONCLUSIONS: Our results suggest that there is call for implementing mental health promotion and prevention strategies at the workplace, along with actions to reduce barriers for accessing psychological support.

RESUMO

BACKGROUND: Evidence-based mental health interventions to support healthcare workers (HCWs) in crisis settings are scarce. OBJECTIVE: To evaluate the capacity of a mental health intervention in reducing anxiety and depression symptoms in HCWs, relative to enhanced care as usual (eCAU), amidst the COVID-19 pandemic. METHODS: We conducted an analyst-blind, parallel, multicentre, randomised controlled trial. We recruited HCWs with psychological distress from Madrid and Catalonia (Spain). The intervention arm received a stepped-care programme consisting of two WHO-developed interventions adapted for HCWs: Doing What Matters in Times of Stress (DWM) and Problem Management Plus (PM+). Each intervention lasted 5 weeks and was delivered remotely by non-specialist mental health providers. HCWs reporting psychological distress after DWM completion were invited to continue to PM+. The primary endpoint was self-reported anxiety/depression symptoms (Patient Health Questionnaire-Anxiety and Depression Scale) at week 21. FINDINGS: Between 3 November 2021 and 31 March 2022, 115 participants were randomised to stepped care and 117 to eCAU (86% women, mean age 37.5). The intervention showed a greater decrease in anxiety/depression symptoms compared with eCAU at the primary endpoint (baseline-adjusted difference 4.4, 95% CI 2.1 to 6.7; standardised effect size 0.8, 95% CI 0.4 to 1.2). No serious adverse events occurred. CONCLUSIONS: Brief stepped-care psychological interventions reduce anxiety and depression during a period of stress among HCWs. CLINICAL IMPLICATIONS: Our results can inform policies and actions to protect the mental health of HCWs during major health crises and are potentially rapidly replicable in other settings where workers are affected by global emergencies. TRIAL REGISTRATION NUMBER: NCT04980326.

RESUMO

INTRODUCTION: Few controlled trials have assessed the impact of Mindfulness Based Cognitive Therapy (MBCT) on symptoms and functioning in bipolar disorder (BD). This study aims to evaluate the effectiveness of MBCT adjunctive group treatment. MATERIAL AND METHODS: Randomized, prospective, multicenter, single-blinded trial that included BP-outpatients with subthreshold depressive symptoms. Participants were randomly assigned to three arms: treatment as usual (TAU); TAU plus psychoeducation; and TAU plus MBCT. Primary outcome was change in Hamilton-D score; secondary endpoints were change in anxiety, hypo/mania symptoms and functional improvement. Patients were assessed at baseline (V1), 8 weeks (V2) and 6 months (V3). Main hypothesis was that adjunctive MBCT would improve depressive symptoms more than psychoeducation. RESULTS: Eighty-four participants were recruited (MBCT=40, Psychoeducation=34, TAU=10). Depressive symptoms improved in the three arms between V1 and V2 (p<0.0001), and between V1 and V3 (p<0.0001), and did not change between V2 and V3. At V3 no significant differences between groups were found. There were no significant differences in other measures either. CONCLUSIONS: In our BD population we did not find superiority of adjunctive MBCT over adjunctive Psychoeducation or TAU on subsyndromal depressive symptoms; neither on anxiety, hypo/mania, relapses, or functioning.

RESUMO

Background and aims: The coronavirus disease 2019 pandemic has challenged health services worldwide, with a worsening of healthcare workers' mental health within initial pandemic hotspots. In early 2022, the Omicron variant is spreading rapidly around the world. This study explores the effectiveness and cost-effectiveness of a stepped-care programme of scalable, internet-based psychological interventions for distressed health workers on self-reported anxiety and depression symptoms. Methods: We present the study protocol for a multicentre (two sites), parallel-group (1:1 allocation ratio), analyst-blinded, superiority, randomised controlled trial. Healthcare workers with psychological distress will be allocated either to care as usual only or to care as usual plus a stepped-care programme that includes two scalable psychological interventions developed by the World Health Organization: A guided self-help stress management guide (Doing What Matters in Times of Stress) and a five-session cognitive behavioural intervention (Problem Management Plus). All participants will receive a single-session emotional support intervention, namely psychological first aid. We will include 212 participants. An intention-to-treat analysis using linear mixed models will be conducted to explore the programme's effect on anxiety and depression symptoms, as measured by the Patient Health Questionnaire - Anxiety and Depression Scale summary score at 21 weeks from baseline. Secondary outcomes include post-traumatic stress disorder symptoms, resilience, quality of life, cost impact and cost-effectiveness. Conclusions: This study is the first randomised trial that combines two World Health Organization psychological interventions tailored for health workers into one stepped-care programme. Results will inform occupational and mental health prevention, treatment, and recovery strategies. Registration details: ClinicalTrials.gov Identifier: NCT04980326.

RESUMO

Background: Healthcare workers (HCWs) from COVID-19 hotspots worldwide have reported poor mental health outcomes since the pandemic's beginning. The virulence of the initial COVID-19 surge in Spain and the urgency for rapid evidence constrained early studies in their capacity to inform mental health programs accurately. Here, we used a qualitative research design to describe relevant mental health problems among frontline HCWs and explore their association with determinants and consequences and their implications for the design and implementation of mental health programs. Materials and methods: Following the Programme Design, Implementation, Monitoring, and Evaluation (DIME) protocol, we used a two-step qualitative research design to interview frontline HCWs, mental health experts, administrators, and service planners in Spain. We used Free List (FL) interviews to identify problems experienced by frontline HCWs and Key informant (KI) interviews to describe them and explore their determinants and consequences, as well as the strategies considered useful to overcome these problems. We used a thematic analysis approach to analyze the interview outputs and framed our results into a five-level social-ecological model (intrapersonal, interpersonal, organizational, community, and public health). Results: We recruited 75 FL and 22 KI interviewees, roughly balanced in age and gender. We detected 56 themes during the FL interviews and explored the following themes in the KI interviews: fear of infection, psychological distress, stress, moral distress, and interpersonal conflicts among coworkers. We found that interviewees reported perceived causes and consequences across problems at all levels (intrapersonal to public health). Although several mental health strategies were implemented (especially at an intrapersonal and interpersonal level), most mental health needs remained unmet, especially at the organizational, community, and public policy levels. Conclusions: In keeping with available quantitative evidence, our findings show that mental health problems are still relevant for frontline HCWs 1 year after the COVID-19 pandemic and that many reported causes of these problems are modifiable. Based on this, we offer specific recommendations to design and implement mental health strategies and recommend using transdiagnostic, low-intensity, scalable psychological interventions contextually adapted and tailored for HCWs.

RESUMO

Objetivo: Analizar la experiencia de los profesionales que atendieron en primera línea a los pacientes infectados durante la primera ola de la pandemia de COVID-19. Material y Métodos: Los participantes fueron reclutados entre médicos y enfermeras de varios hospitales y centros de salud en España. Sus narrativas se obtuvieron a través de tres grupos focales. Se empleó la metodología cualitativa, de acuerdo con sus principios exploratorios, inductivos y etnográficos. Resultados: La experiencia del personal sanitario se clasificó en seis categorías: La reacción y organización de los sanitarios, el material y las pruebas, los aspectos emocionales en relación con la asistencia, los conflictos éticos, la gestión sanitaria de la pandemia y el papel social de los sanitarios. Conclusiones: Los sanitarios adoptaron un rol proactivo durante la pandemia. Se señalan las vulnerabilidades y las fortalezas de la asistencia. Los aspectos que tiene que ver con la regulación emocional de los sanitarios resultan claves para el funcionamiento asistencial. (AU)


Objectives: to analyze the experience of health professionals who provided first-line care to infected patients during the COVID-19 pandemic during the first wave. Material and Methods: Participants were recruited from among physicians and nurses in several hospitals and health centers in Spain. Narratives were obtained through three focus groups. Qualitative methodology was used according to exploratory, inductive, and ethnographic principles. Results: The experience of the health personnel was classified into six categories: The reaction and organization of health workers, materials and tests, emotional aspects of care, ethical conflicts, health management of the pandemic, and the social role of health workers. Conclusions: Healthcare workers took a proactive approach during the pandemic. Weaknesses and strengths in the provision of health care were. The capacity of emotional self-regulation of the health care workers is shown to be key to the ability of the health care system to continue operating. (AU)

RESUMO

We examined whether excess chronic medical comorbidity mediated excess COVID-19 inpatient mortality among people with mental disorders in the early phase of the pandemic, a question with important implications for public health and clinical decision-making. Using records of 2599 COVID-19 hospitalized patients, we conducted a formal causal mediation analysis to estimate the extent to which chronic comorbidity mediates the association between mental disorders and COVID-19 mortality. The Odds Ratio (95% CI) for Natural Indirect Effect and Controlled Direct Effect were 1.07(1.02, 1.14) and 1.40 (1.00, 1.95), respectively, suggesting that a large proportion of excess COVID-19 mortality among people with mental disorders may be explained by factors other than comorbidity.

RESUMO

Objective: To examine any prospective association between neutrophil-to-lymphocyte ratio (NLR) at hospital admission and subsequent delirium in older COVID-19 hospitalized patients comparing by sex and age groups. Methods: The sample consisted of 1,785 COVID-19 adult inpatients (minimum sample size required of 635 participants) admitted to a public general hospital in Madrid (Spain) between March 16th and April 15th, 2020. Variables were obtained from electronic health records. Binary logistic regression models were performed between baseline NLR and delirium adjusting for age, sex, medical comorbidity, current illness severity, serious mental illness history and use of chloroquine and dexamethasone. An NLR cut-off was identified, and stratified analyses were performed by age and sex. Also, another biomarker was tested as an exposure (the systemic immune-inflammation index -SII). Results: 55.3% of the patients were men, with a mean age of 66.8 years. Roughly 13% of the patients had delirium during hospitalization. NLR on admission predicted subsequent delirium development (adjusted OR = 1.02, 95 percent CI: 1.00-1.04, p = 0.024). Patients between 69 and 80 years with NLR values > 6.3 presented a twofold increased risk for delirium (p = 0.004). There were no sex differences in the association between baseline NLR and delirium (p > 0.05) nor SII predicted delirium development (p = 0.341). Conclusion: NLR is a good predictor of delirium during hospitalization, especially among older adults, independently of medical comorbidity, illness severity, and other covariates. Routine blood tests on admission might provide valuable information to guide the decision-making process to be followed with these especially vulnerable patients.

RESUMO

OBJECTIVE: To compare the effect of a mindfulness-based mobile application versus an in-person mindfulness-based training program in terms of reducing anxiety and increasing empathy, self-compassion, and mindfulness in a population of healthcare students. METHODS: The authors conducted a single-blind, randomised controlled trial with three parallel groups. Participants were allocated to the mobile app, the in-person mindfulness-based program (IMBP), or a control group. Assessments at baseline and postintervention (8 weeks) included measures of anxiety, empathy, self-compassion, and mindfulness. RESULTS: Of 168 students randomised, 84 were analysed on an intention-to-treat basis (app: n = 31; IMBP: n = 23; control: n = 30). The mobile app group showed a large effect size for reductions in trait anxiety compared with controls (g = 0.85, p = 0.003), and a medium, nonsignificant effect compared with the IMBP group (g = 0.52, p = 0.152). Participants from both interventions experienced a significant increase in self-compassion and mindfulness compared with controls. Levels of empathy remained unchanged for the 3 arms. CONCLUSIONS: A mobile app can be as effective as an IMBP in reducing anxiety and increasing self-compassion and mindfulness among healthcare students.

RESUMO

OBJECTIVE: This study explores whether social cognition and social functioning improve after a mindfulness-based social cognition training (SocialMIND). METHODS: Thirty-eight outpatients with psychosis completed an assessment with social cognition (Eyes Test, Ambiguous Intentions and Hostility Questionnaire [AIHQ], and Hinting Task) and social functioning tasks (Personal and Social Performance [PSP] scale) before and after eight SocialMIND weekly sessions. Mean differences between timepoints were standardized and 95% confidence intervals were obtained with a paired samples t-test. RESULTS: The scores of the Eyes Test (95% CI [.43, 3.32], d = .48), the Hostility Bias subscale (AIHQ) (95% CI [-.29, -.01], d = .44), and the self-care difficulties subscale (PSP) (95% CI [-.77, -.09], d = .45) improved after the intervention. CONCLUSIONS: and Implications for practice: The results of SocialMIND-8 are very promising in terms of developing comprehensive rehabilitation programs. Further trials must address its effectiveness against a control group during longer follow-up periods. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

Introduction: The COVID-19 outbreak is having an impact on the well-being of healthcare workers. Mindfulness-based interventions have shown effectiveness in reducing stress and fostering resilience and recovery in healthcare workers. There are no studies examining the feasibility of brief mindfulness-based interventions during the COVID-19 outbreak. Materials and Methods: This is an exploratory study with a post intervention assessment. We describe an on-site brief mindfulness intervention and evaluate its helpfulness, safety, and feasibility. Results: One thousand out of 7,000 (14%) healthcare workers from La Paz University Hospital in Madrid (Spain) participated in at least one session. One hundred and fifty out of 1,000 (15%) participants filled out a self-report questionnaire evaluating the helpfulness of the intervention for on-site stress reduction. Ninety two subjects (61%) participated in more than one session. Most of the participants were women (80%) with a mean age of 38.6 years. Almost half of the sample were nurses (46%). Sessions were perceived as being helpful with a mean rating of 8.4 on a scale from 0 to 10. Only 3 people (2%) reported a minor adverse effect (increased anxiety or dizziness). Discussion: Our data supports the utility, safety and feasibility of an on-site, brief mindfulness-based intervention designed to reduce stress for frontline health workers during a crisis. There is a need to continue testing this type of interventions, and to integrate emotion regulation strategies as an essential part of health workers' general training. Clinical Trial Registration number: NCT04555005.

RESUMO

The measures to contain the spread of the COVID-19 outbreak have no precedent in the recent history of many countries. Around 2,000 million people in the world are in isolation or quarantine, and gatherings of people have been expressly banned in many countries. In Spain, this prohibition affects workplaces, schools, and the national health system, where most of the healthcare is being provided either on the phone or online.

RESUMO

BACKGROUND: People who suffer a first episode of psychosis experience higher levels of distress and suffering. Early intervention programs combine pharmacological and psychosocial strategies that include different components, such as cognitive-behavioural therapy, psychosocial interventions, medication adherence, family psychoeducation, counselling, etc. Among the complementary approaches, mindfulness-based interventions help participants to cultivate a radical acceptance of their psychotic experiences within a person-centered framework. They show promising results for people with longer duration of psychosis, but there is still no evidence for people who have recently experienced their first episode of psychosis. METHODS: The present parallel-group, single-blind (evaluator), randomised (1:1 ratio), controlled (versus active comparator), superiority, clinical trial will compare the effectiveness of SocialMIND on social functioning as measured by the Personal and Social Performance (PSP) scale. The active comparator will be a psychoeducational multicomponent intervention (PMI) that incorporates elements of early intervention programs that are effective for people who have suffered a first episode of psychosis. Both SocialMIND and PMI encompass eight weekly sessions, four bi-weekly sessions, and five monthly sessions. Changes in primary and secondary outcomes will be measured after weekly (8th week), bi-weekly (16th week) and monthly sessions (56th week), and 3 months after completing the intervention (68th week). Secondary outcomes include symptoms of psychosis, anxiety and depression, as well as indicators of general functioning. Tertiary outcomes are measures of social cognition, neurocognition, mindfulness, and indicators of inflammation and oxidative stress. A final sample of 80 participants is proposed to detect clinically significant differences in social functioning. DISCUSSION: This is the first mindfulness-based social cognition training for people with psychosis. SocialMIND aims to generate changes in the real-life functioning of people who have experienced a first episode of psychosis, and to be at least as effective as a psychoeducational multicomponent program. Adherence to the interventions is a common problem among young people with psychosis, so several difficulties are anticipated, and some methodological issues are discussed. TRIAL REGISTRATION: The trial was registered in ClinicalTrials.gov in October 2018 (NCT03309475).

RESUMO

Introduction: Difficulties in social functioning are common among people with psychosis. Negative symptoms such as blunted affect or social withdrawal are often linked to these difficulties and worsen real-life outcomes. One important dimension associated with social functioning is social cognition, which refers to the psychological processes that are necessary to perceive, encode, store, retrieve, and regulate social information. Mindfulness-based interventions for people with psychosis are safe and effective in improving anxiety and depressive symptoms; however, no mindfulness-based interventions addressing social cognition have yet been developed. Method: A pilot, single-arm, nonrandomized, noncontrolled feasibility trial is proposed. The main objectives are to assess the tolerability of mindfulness-based social cognition training (SocialMind) and to test the feasibility of a further randomized controlled trial. Results: A final sample of 25 outpatients with schizophrenia spectrum disorders was included. Attrition rate was lower than usual for this population, and most participants completed the training. No adverse effects were identified in terms of hospitalizations, emergency room visits, dissociative and psychotic symptoms, or state of anxiety during the sessions. Conclusion: This is the first implementation of SocialMind, which is the first mindfulness-based social cognition training. It is well tolerated by participants with schizophrenia spectrum disorders, and a further randomized controlled trial is proposed for people who have suffered their first episode of psychosis within the past 5 years.

RESUMO

Objectives. The psychometric properties regarding sex and age for the revised version of the Temperament and Character Inventory (TCI-R) and its derived short version, the Temperament and Character Inventory (TCI-140), were evaluated with a randomized sample from the community. Methods. A randomized sample of 367 normal adult subjects from a Spanish municipality, who were representative of the general population based on sex and age, participated in the current study. Descriptive statistics and internal consistency according to α coefficient were obtained for all of the dimensions and facets. T-tests and univariate analyses of variance, followed by Bonferroni tests, were conducted to compare the distributions of the TCI-R dimension scores by age and sex. Results. On both the TCI-R and TCI-140, women had higher scores for Harm Avoidance, Reward Dependence and Cooperativeness than men, whereas men had higher scores for Persistence. Age correlated negatively with Novelty Seeking, Reward Dependence and Cooperativeness and positively with Harm Avoidance and Self-transcendence. Young subjects between 18 and 35 years had higher scores than older subjects in NS and RD. Subjects between 51 and 77 years scored higher in both HA and ST. The alphas for the dimensions were between 0.74 and 0.87 for the TCI-R and between 0.63 and 0.83 for the TCI-140. Conclusion. Results, which were obtained with a randomized sample, suggest that there are specific distributions of personality traits by sex and age. Overall, both the TCI-R and the abbreviated TCI-140 were reliable in the 'good-to-excellent' range. A strength of the current study is the representativeness of the sample.

RESUMO

BACKGROUND: To analyze the factor structure and psychometric properties of the TFEQ in a morbid obese Spanish sample of bariatric surgery candidates. METHOD: Multi-trait/ multi-item analyses and alpha coefficients were conducted to test the convergent /discriminant validity and the internal consistency reliability. Principal components analyses (varimax) were used to explore the factor structure. Sub-group factor analyses by gender, age and body mass index (BMI) were conducted to identify unstable items. RESULTS: The internal structure of the original TFEQ factors was unsatisfactory, especially the Disinhibition Scale. Most Disinhibition and Hunger items were grouped on one factor labeled “Dysregulation Eating”. Cognitive Restraint was split into two factors. The first one, related to the behavioral component of Restraint, labeled “Restrained Behaviour” and the second one related to weight and eating concerns called “Predisposition to Restraint”. CONCLUSIONS: The original factor structure of the TFEQ was not replicated. A revised 23-item instrument, representing the three new derived factors is offered as a valid screening instrument for severely obese patients.

RESUMO

BACKGROUND: Legionella testing conducted at environmental laboratories plays an essential role in assessing the risk of disease transmission associated with water systems. However, drawbacks of culture-based methodology used for Legionella enumeration can have great impact on the results and interpretation which together can lead to underestimation of the actual risk. Up to 20% of the samples analysed by these laboratories produced inconclusive results, making effective risk management impossible. Overgrowth of competing microbiota was reported as an important factor for culture failure. For quantitative polymerase chain reaction (qPCR), the interpretation of the results from the environmental samples still remains a challenge. Inhibitors may cause up to 10% of inconclusive results. This study compared a quantitative method based on immunomagnetic separation (IMS method) with culture and qPCR, as a new approach to routine monitoring of Legionella. RESULTS: First, pilot studies evaluated the recovery and detectability of Legionella spp using an IMS method, in the presence of microbiota and biocides. The IMS method results were not affected by microbiota while culture counts were significantly reduced (1.4 log) or negative in the same samples. Damage by biocides of viable Legionella was detected by the IMS method. Secondly, a total of 65 water samples were assayed by all three techniques (culture, qPCR and the IMS method). Of these, 27 (41.5%) were recorded as positive by at least one test. Legionella spp was detected by culture in 7 (25.9%) of the 27 samples. Eighteen (66.7%) of the 27 samples were positive by the IMS method, thirteen of them reporting counts below 10(3) colony forming units per liter (CFU l(-1)), six presented interfering microbiota and three presented PCR inhibition. Of the 65 water samples, 24 presented interfering microbiota by culture and 8 presented partial or complete inhibition of the PCR reaction. So the rate of inconclusive results of culture and PCR was 36.9 and 12.3%, respectively, without any inconclusive results reported for the IMS method. CONCLUSION: The IMS method generally improved the recovery and detectability of Legionella in environmental matrices, suggesting the possibility to use IMS method as valuable indicator of risk. Thus, this method may significantly improve our knowledge about the exposure risk to these bacteria, allowing us to implement evidence-based monitoring and disinfection strategies.
