Background: Insomnia significantly impairs healthcare worker (HCW) well-being, particularly amid COVID-19 sequelae and shift work demands. We aimed to assess the prevalence of insomnia among HCWs, identify those needing clinical intervention, analyze shift work as a potential risk factor, and explore associations with COVID-19 sequelae and psychiatric comorbidities. Methods: A cross-sectional online survey was administered at the University of Salamanca University Care Complex (CAUSA) from March 2023 to January 2024. Validated scales (Insomnia Severity Index, Patient Health Questionnaire-4, Generalized Anxiety Disorder Scale-2) were used to measure insomnia, depression, and anxiety. Participants scoring ISI ≥ 7 were invited for Occupational Medicine follow-up. Descriptive and inferential analyses were performed. Results: Overall, 1121 HCWs participated (mean age 44.59 ± 11.78, 78.3% women). The mean ISI score was 10.5 ± 5.8 (subclinical insomnia), with 22.7% reporting moderate and 3% reporting severe insomnia. Depression and anxiety affected 28.4% and 33% of respondents, respectively. Shift workers had poorer sleep (mean ISI 11.3 ± 0.9 vs. 8.8 ± 0.3, p < 0.001). Individuals reporting COVID-19 sequelae were 3.1 times more likely to have insomnia than those who did not (mean ISI 13.89 ± 5.9 vs. 10.33 ± 5.7, p < 0.001). Over one-quarter reported at least the monthly use of sleep or psychiatric medications. Conclusions: Insomnia remains prevalent among HCWs, influenced by shift work, COVID-19 sequelae, and mental health factors. Targeted, multidisciplinary interventions, e.g., workplace policy changes, mental health programs, and shift schedule adjustments are urgently needed to safeguard well-being, reduce burnout, and maintain quality patient care. Ensuring adequate sleep is central to minimizing errors and preserving professional performance. Future studies should investigate the impact of coordinated workplace strategies to effectively address insomnia.

This study examines the relevance of interpersonal relationships in the work environment, focusing specifically on analyzing associations between positive relational management, which refers to the use of relational resources that enable adaptation to the workplace, and key organizational variables such as flourishing, individual-directed organizational citizenship behaviors (OCBis), and life satisfaction. Given the importance of this topic, a structural model is required for the possible relationship between positive relational management and other organizational variables relevant to occupational well-being. As a preliminary step, the Positive Relational Management Scale (PRMS) was analyzed and validated in a sample of 348 Spanish workers. The results revealed that the overall model has a good fit, with reliable and valid construct measures. Moreover, the three-dimensional structure of the model was confirmed, although gender invariance was not satisfied. In conclusion, the results confirm the simple mediation hypothesis, in which flourishing mediates the relationship between positive relational management and life satisfaction. In contrast, multiple mediations between the variables could not be confirmed. This study highlights the importance of interpersonal relationships for employee well-being in the workplace.

Background: Benzodiazepines (BZDs), commonly used to treat insomnia and anxiety, are increasingly used in Spain, raising concerns due to their potential for abuse and dependence. This study investigates the use of BZDs and other psychotropic medications among healthcare workers, exploring their prevalence, associated factors, and their relationship with mental health issues following the COVID-19 pandemic. Methods: An anonymous online survey was conducted among healthcare workers at the Salamanca University Healthcare Complex (CAUSA) from March 2023 to January 2024. Of 1121 participants, 685 provided complete responses, which were analysed. Insomnia, anxiety, and depression were assessed using the Insomnia Severity Index (ISI) and Patient Health Questionnaire-4 (PHQ-4). Results: Of the respondents, 23.8% reported using sleep medication, with 27.8% doing so without a prescription. Additionally, 14.7% used medication for depression or anxiety, with only 0.6% without a prescription. Hypnotic medicine use was associated with older age, insomnia, anxiety, depression, psychological or psychiatric treatment, COVID-19 after-effects, and diagnosed sleep disorders. Night-shift work was associated with increased hypnotic medication use in men but not in women. The use of these medications was linked to a reduced quality of life and impaired work performance. Conclusions: The use of BZD and self-medication are prevalent among healthcare professionals, exceeding the rates observed in the general population. These findings highlight the urgent need for targeted interventions to address psychotropic medication use, promote other pharmacological and non-pharmacological alternatives for insomnia, and enhance mental health support for this vulnerable population.
