Malawian critical care nurses' views on the implementation of an educational intervention to enhance sustained use of an evidence-based endotracheal tube cuff pressure management guideline: A survey study

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); f=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

Carbon dioxide levels of ventilated adult critically ill post-operative patients on arrival at the intensive care unit

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

Prevalence and independent predictors of in-hospital stroke among patients who developed acute alteration of consciousness in the medical intensive care unit: A retrospective case-control study

BACKGROUND: In-hospital stroke is a serious event, associated with poor outcomes and high mortality. However, identifying signs of stroke may be more difficult in critically ill patients OBJECTIVES: This study investigated the prevalence and independent predictors of in-hospital stroke among patients with acute alteration of consciousness in the medical intensive care unit (MICU) who underwent subsequent brain computed tomography (CT METHODS: This retrospective study enrolled eligible patients during the period 2007 - 2017. The alterations researched were radiologically confirmed acute ischaemic stroke (AIS) and intracerebral haemorrhage (ICH RESULTS: Of 4 360 patients, 113 underwent brain CT. Among these, 31% had AIS, while 15% had ICH. They had higher diastolic blood pressures and arterial pH than non-stroke patients. ICH patients had higher mean (standard deviation (SD) systolic blood pressures (152 (48) v. 129 (25) mmHg; p=0.01), lower mean (SD) Glasgow Coma Scale scores (4 (3) v. 7 (4); p=0.004), and more pupillary abnormalities (75% v. 9%; p<0.001) than AIS patients. AIS patients were older (65 (18) v. 57 (18) years; p=0.03), had more hypertension (60% v. 39%; p=0.04), and more commonly presented with the Babinski sign (26% v. 9%; p=0.04). Multivariate analysis found that pupillary abnormalities independently predicted ICH (adjusted odds ratio (aOR) 26.9; 95% CI 3.7 - 196.3; p=0.001). The Babinski sign (aOR 5.1; 95% CI 1.1 - 23.5; p=0.04) and alkalaemia (arterial pH >7.4; aOR 3.6; 95% CI 1.0 - 12.3; p=0.05) independently predicted AIS CONCLUSIONS: Forty-six percent of the cohort had ICH or AIS. Both conditions had high mortality. The presence of pupillary abnormalities predicts ICH, whereas the Babinski sign and alkalaemia predict AIS

Healthcare professionals' perception of knowledge and implementation of Patient Safety Incident reporting and learning guidelines in specialised care units, KwaZulu-Natal

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