The digital expansion in medicine and healthcare has been immense and extremely valuable. The biggest concern in the face of this inevitable growth is how we manage to keep contact with our patients and preserve the human touch so essential in healing. Digital healthcare should not be about technology replacing clinicians. Instead, it should be about augmenting and supplementing healthcare providers to improve the ways in which we deliver personalised healthcare. It is vital that we focus on how we can revitalise the patient-clinician relationship in this digital age.

Background: Evidence-based guidelines can assist critical care nurses in promoting best practices, including those related to endotracheal tube cuff pressure management. However, these guidelines require tailored strategies to enhance their implementation, uptake, and sustained use in practice.

Objectives: To evaluate Malawian critical care nurses' views on the implementation of an endotracheal tube cuff pressure management guideline to enhance sustained guideline use.

Methods: An explorative-descriptive survey design was employed, using a questionnaire with closed- and open-ended questions that was distributed after implementation of an educational intervention based on an endotracheal tube cuff pressure management guideline. The questionnaire had a Cronbach's alpha score of 0.85.

Results: A total of 47 nurses working in four public and two private hospital intensive care units in Malawi participated. Quantitative findings showed that the majority of the participants (92%) indicated that the strategies used for the group that received the full intervention including both active (monitoring visits) and passive (a half-day educational session using a PowerPoint presentation, and a printed guideline and algorithm) strategies (intervention 1 group) were useful, clear and applicable and enhanced implementation of the guideline. These results were statistically significant (mean (standard deviation) 1.86 (0.84); t=6.07; p<0.0005). Qualitative data revealed three major themes related to recommendations for uptake and sustained use of the guideline in nursing practice: the guideline needs to be translated, updated, and made available to ICU staff; implementation strategies (continuous supervision and follow-up); and facilitating factors for successful implementation (education and training on guideline content, resources, and commitment to best practices).

Conclusion: The study highlighted that although the implementation strategies used were positively received by participants, they need to be further tailored to their context to enhance guideline uptake and sustained use in practice. Further study is required to ensure that tailored implementation strategies facilitate guideline uptake and sustained use, specifically in resource-constrained contexts.

Contributions of the study: The study findings can be used by nurses and academics when developing educational interventions for critical care units to enhance implementation of guidelines in this context.

Background: Despite the implementation of intervention strategies, incidents in specialised care units remain high and are of serious concern, worldwide.

Objectives: To assess the healthcare professionals' perception of knowledge and implementation of patient safety incident (PSI) reporting and learning guidelines in specialised care units of three selected public hospitals in KwaZulu-Natal, South Africa.

Methods: The study used a descriptive, cross-sectional survey design. A purposive sample targeted 237 healthcare professionals. An online structured questionnaire collected the data. Descriptive and inferential statistics were used to analyse data.

Results: A total of 181 questionnaires were returned, yielding a response rate of 76%. Notably, 83% of respondents had high-perceived knowledge of the PSI reporting and learning guidelines, while 98% had low perceptions of their implementation. The current unit (p=0.002) and shift of the day (p=0.008) were factors associated with the perception of good knowledge of PSI reporting and learning guidelines, as indicated by a p-value ≤0.05. The respondents' age (p=0.05), current unit (p=0.015), and shift of the day (p=0.000) were significantly associated with the perception of poor implementation of the PSI reporting and learning guidelines.

Conclusion: The respondents demonstrated a good perception of knowledge of PSI reporting and learning guidelines; however, the perception of the implementation was poor. Therefore, a revised implementation strategy coupled with periodical in-service training for healthcare professionals is recommended, to foster and facilitate effective adherence to PSI reporting and learning guidelines.

Contributions of the study: This study highlights the healthcare professionals' perception of knowledge and implementation of the Patient Safety Incident reporting and learning guidelines in specialised care units in South Africa. The results identified weaknesses in the implementation of the guidelines; hence the necessity for the development of effective strategies to improve patient safety.

Background: There are limited data on the clinical characteristics and outcomes of patients with myasthenia gravis (MG) admitted to the intensive care unit (ICU) at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH).

Objectives: The aim was to study the clinical characteristics and outcomes of patients with MG admitted to the CMJAH over two decades.

Methods: A retrospective study was undertaken of patients with MG admitted to the multidisciplinary ICU of CMJAH over a 20-year period, from 1998 to 2017. Demographic data, clinical features, management and outcomes of patients were assessed and reviewed from the case records.

Results: Thirty-four patients with MG were admitted to the ICU during this period: 24 female and 10 male. The mean age ± SD was 37.4 ± 13.0 years, with a range of 16 - 66 years. Four patients were human immunodeficiency virus (HIV)-positive. The mean length of stay (LOS) in ICU was 10.6 ± 20.1 days, ranging from 1 to 115 days. Two patients were diagnosed with MG in the ICU after failure to wean from the ventilator. Overall, 22 patients were intubated and ventilated on admission. Morbidities included self-extubation, aspiration pneumonia and iatrogenic pneumothorax. History of thymectomy was present in 12 patients. The treatments received for MG included pyridostigmine (73.5%), corticosteroids (55.9%), azathioprine (35.3%), plasmapheresis (26.5%) and intravenous immunoglobulin (8.8%). The overall mortality in the ICU was 5.9%.

Conclusion: MG is a serious disorder with considerable morbidity and mortality. It is, however, a potentially manageable disease, provided that appropriate ICU resources are available.

Contributions of the study: This study provides further insight into the characteristics and outcomes of myasthenia gravis patients in ICU, within a South African context.

Background: In this Cochrane Corner, we highlight the main findings of a Cochrane Review by Flumignan et al. entitled 'Anticoagulants for people hospitalised with COVID-19' and discuss the implications of these findings for research and practice in South Africa. In particular, we underscore the need for additional, high-quality, randomised controlled trials comparing different intensities of anticoagulation in patients with COVID-19 illness. Individuals in the intensive care unit and those hospitalised with another illness who are incidentally found to be infected with SARS-CoV-2 should still only be treated with prophylactic-dose low-molecular-weight heparin.

Contributions of the study: This Cochrane Corner summarises findings in a recent systematic review on the use of anticoagulation in people hospitalised with COVID-19, and provides insights on the implications of these findings for implementation by clinicians in South Africa. It highlights the need for clinicians to balance the benefits and harms of providing an anticoagulant, while considering the patients underlying risk for bleeding and thromboembolism.

Background: A critical care unit admits on a daily basis patients who are critically ill or injured. The condition of these patients' may deteriorate to a point where the medical practitioner may prescribe or decide on a 'do not resuscitate' (DNR) order which must be executed by a professional nurse, leading to moral distress which may manifest as poor teamwork, depression or absenteeism.

Objectives: To explore and describe factors contributing to moral distress of critical care nurses executing DNR orders.

Design: The explorative descriptive qualitative design was selected to answer the research questions posed.

Methods: Critical care nurses of a selected public hospital in Gauteng Province were selected via purposive sampling to participate in the study, and data were collected through semi-structured interviews.

Particpants: A shift leader assisted with selection of participants who met the eligibility criteria. The mean age of the participants was 36 years; most of them had more than five years' critical care nursing experience. Twelve critical care nurses were interviewed when data saturation was reached. Thereafter two more interviews were conducted to confirm data saturation. A total of 14 interviews were conducted.

Results: Tesch's eight-step method was utilised for data analysis. The findings were classified under three main themes: moral distress, communication of DNR orders and unavailability of psychological support for nurses.

Conclusion: The findings revealed that execution of DNR orders is a contributory factor for moral distress in critical care nurses. National guidelines and/or legal frameworks are required to regulate processes pertaining to the execution of DNR orders. The study further demonstrated the need for unit-based ethical platforms and debriefing sessions for critical care nurses.

Contribution of the study: The main contribution of this study was to explore and describe the factors contributing to Moral distress when executing a DNR order. This study raised awareness amongst healthcare providers on the factors contributing to moral distress amongst critical care nurses. This study highlighted the importance of developing national guidelines and legal frameworks pertaining to execution of DNR orders. This study alluded to the value of initiating debriefing sessions for critical care nurses involved in the execution of DNR orders.

Background: The transportation of critically ill patients presents a precarious situation in which adverse events may occur. At Chris Hani Baragwanath Academic Hospital (CHBAH) patients were manually ventilated using a manual resuscitator bag during transportation from theatre to the intensive care unit (ICU).

Objectives: To evaluate the arterial partial pressure of carbon dioxide (PaCO₂ ) levels of ventilated adult critically ill post-operative patients on arrival at the ICU at CHBAH.

Methods: This was a cross-sectional study using convenience sampling. Pre- and post-transportation arterial blood gases were obtained from 47 patients.

Results: There was a statistically significant difference in the pre- and post-transport PaCO₂ level (p=0.03), with a mean difference of 3.3 mmHg. The pre- and post-transport arterial partial pressure of oxygen (PaO₂ ) level (p≤0.001) and the week and weekend pre-transport (p≤0.001) and post-transport (p=0.01) PaCO₂ were statistically significantly different. No statistically significant difference was found in the other arterial blood gas parameters or in the post-transport PaCO₂ of those patients (26 (55.3%)), who received a neuromuscular blocking drug compared with those that did not. Adverse events were noted during 12 (25.6%) of the transports, 5 (41.7%) of which were patient-related, and 7 (58.3%) of which were infrastructure-related.

Conclusion: There was a statistically but not clinically significant difference in the pre- and post-transport PaCO₂ level and between week and weekend transportations. Hypercarbia was the most common derangement in all transports. Adverse events occurred during one-quarter of transportations.

Contributions of the study: This study evaluated the PaCO₂ levels of critically ill patients at CHBAH during transportation from theatre to the ICU. The findings indicate that manual ventilation was not injurious. The authors recommend reproducing the study in patients with severe ARDS and pulmonary hypertension to ascertain if manual ventilation is safe in this population; and also with healthcare practitioners other than anaesthesiologists, who may not be as experienced in manual ventilation.
