Cybersecurity and critical care staff: A mixed methods study.

INTRODUCTION: Cyberattacks on healthcare organisations are becoming increasingly common and represent a growing threat to patient safety. The majority of breaches in cybersecurity have been attributed to human error. Intensive care departments are particularly vulnerable to cyberattacks. The aim of this study was to investigate cybersecurity awareness, knowledge and behaviours among critical care staff. METHODS: This was a multi-site cross-sectional survey study administered to critical care staff. Cybersecurity awareness was evaluated using the validated HAIS-Q instrument. Knowledge and behaviours were evaluated by direct questioning and scenario-based multiple-choice questions. Free text options were also offered to respondents. Thematic analysis was performed on free text sections. RESULTS: Median scores of 12-15 in each of the HAIS-Q focus areas were achieved, indicating high levels of cybersecurity awareness among critical care staff. However, self-reported confidence in cybersecurity practices, especially identifying signs of cybersecurity breaches and reporting cybersecurity incidents, were relatively low. Participants responses to the scenarios demonstrated a lack of knowledge and awareness of some of the mechanisms of cyberattacks. Barriers to safe cybersecurity practices among staff that emerged from the qualitative analysis included: a lack of training and education; heavy workloads and staff fatigue; perceived lack of IT support and poor IT infrastructure. CONCLUSION: Critical care staff appear to have a high-level cybersecurity awareness. However, in practice safe cybersecurity practices are not always followed. ICU departments and hospitals must invest in the human aspect of cybersecurity to strength their cyber-defences and to protect patients.

The relationship between physician burnout and depression, anxiety, suicidality and substance abuse: A mixed methods systematic review.

Introduction: The World Health Organization defines burnout as a problem associated with employment, a category distinct from psychological disorders such as depression, anxiety, suicidality and disorders of substance abuse. Evaluating the association between burnout as an occupational exposure and psychological morbidity may indicate that burnout can act as an occupational risk factor for mental ill-health. The systematic review explores this relationship in physicians due to the increased risk in this population and the implications for healthcare delivery. Methods: A mixed methods systematic review of the literature was conducted across Medline, Cinahl Plus, PsycInfo, Web of Science and The Cochrane Library. Databases were systematically searched using keywords relating to physician burnout and depression, anxiety, suicidality and substance abuse. Identified articles were screened for eligibility by two independent researchers. Data extraction was performed and studies assessed for risk of bias. Quantitative and qualitative results were integrated using a convergent segregated approach and results portrayed as a narrative synthesis. Results: Sixty-one articles were included in the review. There was notable heterogeneity in the measurement and criteria used to define burnout limiting the assimilation of results. Despite this, all studies that measured the association between depression and burnout reported a significant association. Studies that reported association between burnout and anxiety were similarly uniformly consistent. Most studies that reported the association between burnout and suicidality indicated that a significant association exists however difficulty in measurement of suicidality may have influenced variability of results. The reported association between substance abuse and burnout was more variable, suggesting that any association is likely to be weak or influenced by other variables. Qualitative studies described the manifestations of chronic workplace stress as well as perceived links with psychological morbidity. These included lack of time for work-life balance, the contribution of professional relationships and a culture of invulnerability that exists among physicians. Conclusion: The systematic review cannot conclude causality but suggests that physician burnout is associated with depression, anxiety and suicidality. Qualitative data provides insight into the nature of this association. The review indicates the need for longitudinal research and provides considerations for intervention strategies to prevent the development and progression of burnout.

Umbilical cord shortening: quantification postdelivery and postfixation.

The length of the umbilical cord is an important data item, and little is known about the effects of time and fixation on measurement. Such a change has implications for the diagnosis of a long and short cord. This study was conducted to examine the effects of time and formalin fixation on cord length in a routine practice setting. We measured 90 cords from singleton term pregnancies within 5 minutes of delivery, again in the fresh state at 1 to 2 hours, and again after 24 to 48 hours of formalin fixation. The mean cord length was 536.7 mm at delivery. Mean cord shortening was 17.6 mm (3% reduction in length) between delivery and measurement at 1 to 2 hours, and 62.2 mm (12% reduction) between delivery and measurement after 24 to 48 hours fixation. Both values were statistically significant (P < 0.001). Studies on cord length should include data on time of measurement and fixation status.
