Background: With the increasingly demanding healthcare environment, patient safety issues are only becoming more complex. This urges nursing leaders to adapt and master effective leadership; particularly, transformational leadership (TFL) is shown to scientifically be the most successfully recognized leadership style in healthcare, focusing on relationship building while putting followers in power and emphasizing values and vision. Aim: To examine how transformational leadership affects nurses’ job environment and nursing care provided to the patients and patients’ outcomes. Design: A systematic literature review was conducted. From 71 reviewed, 23 studies were included (studies included questionnaire surveys and one interview, extracting barriers and facilitators, and analyzing using qualitative synthesis). Result: TFL indirectly and directly positively affects nurses’ work environment through mediators, including structural empowerment, organizational commitment, and job satisfaction. Nurses perceived that managers’ TFL behavior did not attain excellence in any of the included organizations, highlighting the necessity for additional leadership training to enhance the patient safety culture related to the non-reporting of errors and to mitigate the blame culture within the nursing environment. Conclusion: Bringing more focus to leadership education in nursing can make future nursing leaders more effective, which will cultivate efficient teamwork, a quality nursing work environment, and, ultimately, safe and efficient patient outcomes. This study was not registered.

Certain Health Workers (HWs) may have inadequate knowledge and perceptions regarding COVID‐19. As a result, they may not be completely aware of the danger/risk involved, which could impact their ability to control the spread of the virus. This systematic review aims to enhance HWs' knowledge and their perception of the spread risk of COVID‐19 during the pandemic. A search was conducted in four databases (Medline, CINAHL, Scopus, and ScienceDirect) to locate peer‐reviewed studies published in English between January 2020 and April 2020. Eventually, nine articles satisfied the inclusion criteria and were, therefore, included in the present study. Six of the aforementioned studies specifically investigated HWs' perception of risk. Apart from a study that indicated medium perception (min = 56.5%), all other studies found high levels of risk perception (n = 5, max 92.1%). As for HWs' knowledge, apart from two studies that indicated medium percentage levels (min = 56.5%), the rest of the studies report high percentages (n = 7, max = 93.2%). Two of the studies, which assessed the sources of information that HWs use, agree that social media is the most widely used source of information. The findings of this study suggest that HWs had a satisfactory perception of risk during the spread of COVID‐19. Although fields with medium knowledge levels were identified, HWs' overall knowledge may also be described as satisfactory. It is also noted that certain demographic characteristics (occupation, age, and years of experience) appear to affect HWs' knowledge and perceptions. The application of educational strategies aiming to provide continuous support to HWs is unanimously recommended by all studies.

The acceptance of an individual to be vaccinated following the introduction of a new vaccine is dependent on multiple factors. Governing factors directing one’s decision to be vaccinated against severe acute respiratory syndrome coronavirus 2, however, are currently unknown and the present study aims at researching these factors within the population of cancer patients. A cross-sectional self-administered survey was conducted anonymously between 22 January and 12 February 2021, during the second vaccination phase against severe acute respiratory syndrome coronavirus 2 in Cyprus. The data were collected via an online questionnaire which was formerly used by previously conducted studies. The Mann–Whitney U test was applied for the comparison of means between bivariate variables, while the Kruskal–Wallis test was used for the comparison of means in variables with more than two groups. In addition, Spearman correlation coefficients were applied to explore the correlation of continuous variables. The sample size consisted of a total of 211 cancer patients, 64.9% of which were women with a mean age of 52.6 ± 12.4 years. The findings of the current research indicate a moderate vaccination acceptance among cancer patients (Μ = 3.3 ± 0.7, R = 1–5). During the promotion of a vaccine against severe acute respiratory syndrome coronavirus 2 to cancer patients, particular emphasis on specific demographic characteristics, vaccination history and preferred sources of informing the individual are required. In addition, through reviewing the prospective effectiveness and possible outcomes of the specific vaccine according to cancer type and anti-cancer therapy, many of the existing concerns and reservations from cancer patients are expected to be diminished.

Pressure ulcers (PUs) are a major health concern. In today's tech era, mobile health applications (mHealth apps) offer real-time data, efficient scheduling, and automation, leading to cost-effective care and improved patient satisfaction. This study aimed to assess the feasibility of a novel preventive mobile health application targeted at informal caregivers of outpatients at risk of developing pressure ulcers. In this quasi-experimental study, 23 Informal Caregivers (ICs) were assigned to the intervention group, and 22 to the control group (n = 45). Feasibility was assessed by considering app utility, ease of use, knowledge gaps in prevention, PU rates, and ICs' self-efficacy. Data was collected at baseline, 2 months, and 4 months, and analyzed using descriptive statistics and inferential analysis. Group disparity in improvement: Prevention knowledge (p = 0.040) and patient support efficacy (p = 0.049). Control experienced no shift; Intervention (mHealth app) showed progress. Initial app acceptance was low but grew after 4 months (p = 0.010). After 4 months, perceived usefulness was linked to support efficacy (r = 0.40, p = 0.05), despite steady ease of use perception. This investigation proposes that the innovative preventative mHealth app has the potential to be viable and is well-received among ICs caring for outpatients at risk of developing PUs. In addition, the temporal fluctuations in metrics between the groups suggest that this application could serve as an advantageous instrument in aiding the efforts of ICs in PU prevention.

Introduction: Pressure ulcers are a significant health concern. In today's tech era, mobile health applications offer real-time data, efficient scheduling, and automation, leading to cost-effective care and improved patient satisfaction. This study aimed to assess the feasibility of a novel preventive mobile health application named "PressureUlcerAdvisor," targeted at informal caregivers of outpatients at risk of developing pressure ulcers.Material and Methods: In this rigorous quasi-experimental study, 23 informal caregivers were assigned to the intervention group and 22 to the control group (n=45). Feasibility was assessed by considering app utility, ease of use, knowledge gaps in prevention, pressure ulcer rates, and caregivers' self-efficacy. Data was collected at baseline, two, and four months and analyzed using a combination of descriptive statistics and inferential analysis, ensuring the reliability and validity of the findings.Results: The study found a significant improvement in the prevention knowledge (p=0.040) and patient support efficacy (p=0.049) between the control and intervention groups. The control group did not show any progress, while the intervention group did. Notably, the initial acceptance of the app, though low, showed a promising upward trend, improving significantly after four months (p=0.010). Additionally, after four months, perceived usefulness was positively associated with patient support efficacy (r=0.40, p=0.05) despite the perceived ease of use remaining steady.Conclusion: This investigation suggests that the innovative preventative mobile health application, 'PressureUlcerAdvisor,' can be a game-changer for caregivers. It is well-received among caregivers caring for outpatients at risk of developing pressure ulcers. The study's positive outcomes, including a significant improvement in prevention knowledge and patient support efficacy, hint at the potential of this application to significantly aid caregivers' efforts in pressure ulcer prevention, empowering them with knowledge and tools to provide better care.
