Are circadian rhythms in disarray in patients with chronic critical illness?

Aim

The aim of our study is to assess circadian rhythms in patients with chronic critical illness due to severe brain injury in intensive care unit by establishing the relation between melatonin and cortisol secretion, considering astronomical time and the sleep-wake cycle in chronic critical illness.

Materials and methods

The study included 54 adult patients with chronic critical illness who resided in the intensive care unit for at least 30 days. The level of consciousness was determined using the CRS-R scale. We did the continuous electroencephalographic (EEG) monitoring with polygraphic leads for 24 h. Also, we determined the serum levels of cortisol and melatonin using the tandem mass spectrometry method with ultra-performance liquid chromatography.

Results

90.74 % of patients had one acrophase in melatonin secretion curve, which suggests the preservation of the rhythmic secretion of melatonin. These acrophases of the melatonin rhythm occurred during the night time in 91.8 % of patients. Most of the patients (69.3 %) slept during the period from 2:00 to 4:00 a.m. The evening levels of cortisol and melatonin had an inverse relation (rs=0.61, p<0.05), i.e., a decrease in the level of cortisol secretion accompanies an increase in melatonin.

Conclusions

We concluded from our study that the rhythmic secretion of melatonin and cortisol is preserved in patients with chronic critical illness that resulted from severe brain injury. No statistically significant discrepancy between melatonin and cortisol secretion, day-and-night time and the sleep-wake cycle are found. We may focus our future work on finding more reliable methods to stabilize the preservation of circadian rhythms to protect vital organ functions.

Impact of a patient and family participation education program on hospital nurses' attitudes and competencies: A controlled before-after study

Objective

We designed a Patient and Family Participation Education Program (PFEP) with the aim of fostering a positive attitude and enhancing the competencies of hospital nurses required for effective patient and family participation in care.

Methods

In a Dutch university hospital, we conducted a before-after study. The PFEP comprising three courses: family conversation, supporting shared decision-making, and health literacy. We assessed nursing attitudes using the FINC-NA questionnaire and competencies with a separate questionnaire before and three months after the program. Changes in attitudes and competencies were analyzed using regression analysis.

Results

Twenty-two nurses participated in the education group, and 58 participated as controls.After three months, the change scores for the education group were statistically significantly higher on the total attitude score (FINC-NA) compared to the control group. Moreover, in six out of twelve competencies, the education group demonstrated significantly higher scores than the control group.

Conclusion

The educational program appeared effective in promoting nurses' attitudes and feelings of competencies towards patient and family-centered care.

Innovation

A blended education program focusing on patient and family has potential value for implementation in hospital care settings, especially for hospitals aiming to cultivate a more patient- and family-centered environment.

Nurse assistants' experiences of encountering patients in grief due to the death of a loved one - a qualitative study in municipal health and social care

PURPOSE

The aim was to explore nurse assistants´ experiences of paying attention to and encountering patients receiving municipal health and social care, who are in grief due to the death of a loved one.

METHODS

A qualitative study with focus group interviews (n = 6) was conducted with nurse assistants (NAs) (n = 28) in municipal health and social care (n = 5) in southern Sweden. The data were analysed inductively using qualitative content analysis.

RESULTS

Three categories (1) Noticing changes in the patient, (2) Using different strategies to create a dialogue with the patient, (3) Experiencing challenges when encountering patients in grief, included eight sub-categories were identified. The result is captured in the theme of Having to be attentive to signs of grief after patients´ loss of loved ones, sensing the right time to approach and comfort, while having to cope with emotional challenges.

CONCLUSIONS

The NAs encountered expressions of strong emotions from patients in grief, and even expressions of a desire to end their lives. Additionally, the NAs had to deal with their own emotions that were evoked when meeting patients in grief. These challenges indicate the need for enhanced conditions in the work culture, and improved training and supervision in health and social care.

Being a patient in the intensive care unit: a narrative approach to understanding patients' experiences of being awake and on mechanical ventilation

PURPOSE

Intensive care patients often struggle to communicate due to the technical equipment used for mechanical ventilation and their critical illness. The aim of the study was to achieve a deeper understanding of how mechanically ventilated intensive care patients construct meaning in the unpredictable trajectory of critical illness.

METHODS

The study was a part of a larger study in which ten patients were video recorded while being in the intensive care. Five patients engaged in interviews about their experiences from the intensive care stay after being discharged and were offered the possibility to see themselves in the video recordings. A narrative, thematic analysis was applied to categorize the patients' experiences from the intensive care.

RESULTS

A pattern of shared experiences among intensive care patients were identified. Three main themes capture the patient's experiences: 1) perceiving the intensive care stay as a life-changing turning point, 2) being dependent on and cared for by others, and 3) living with negative and positive ICU experiences.

CONCLUSION

The patients' narratives revealed how being critically ill affected them, and how they understood their experiences in relation to themselves and their surroundings. The results can be used to pose important questions about our current clinical practice.

Live music in the intensive care unit - a beautiful experience

BACKGROUND

The growing number of lightly or non-sedated patients who are critically ill means that more patients experience the noisy and stressful environment. Live music may create positive and meaningful moments.

PURPOSE

To explore non-sedated patients' experiences of patient-tailored live music interventions in the intensive care unit.

DESIGN

A qualitative study using a phenomenological-hermeneutic approach. Data were collected at two intensive care units from September 2019 to February 2020 exploring 18 live music interventions performed by music students from The Royal Academy of Music, Aarhus, Denmark.

METHODS

Observations of live music interventions followed by patient interviews. All data together were analysed using Ricoeur's theory of interpretation. The Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist was used.

RESULTS

Five themes emerged: 1) A break from everyday life, 2) A room with beautiful sounds and emotions, 3) Too tired to participate, 4) Knowing the music makes it meaningful and 5) A calm and beautiful moment.

CONCLUSION

Patient-tailored live music to awake patients is both feasible and acceptable and perceived as a break from every-day life in the ICU.

IMPLICATIONS FOR PRACTICE

Supporting health and well-being by bringing a humanizing resource into the intensive care setting for patients and nurses to enjoy.

The Application of Diaphragm Ultrasound in Chronic Obstructive Pulmonary Disease: A Narrative Review

Chronic Obstructive Pulmonary Disease (COPD) is a prevalent condition that poses a significant burden on individuals and society due to its high morbidity and mortality rates. The diaphragm is the main respiratory muscle, its function has a direct impact on the quality of life and prognosis of COPD patients. This article aims to review the structural measurement and functional evaluation methods through the use of diaphragmatic ultrasound and relevant research on its application in clinical practice for COPD patients. Thus, it serves to provide valuable insights for clinical monitoring of diaphragm function in COPD patients, facilitating early clinical intervention and aiding in the recovery of diaphragm function.

Study of the intensive care unit activity scale in the early rehabilitation of patients after direct cardiac surgery

BACKGROUND

Direct cardiac surgery often necessitates intensive post-operative care, and the intensive care unit (ICU) activity scale represents a crucial metric in assessing and guiding early rehabilitation efforts to enhance patient recovery.

AIM

To clarify the clinical application value of the ICU activity scale in the early recovery of patients after cardiac surgery.

METHODS

One hundred and twenty patients who underwent cardiac surgery between September 2020 and October 2021 were selected and divided into two groups using the random number table method. The observation group was rated using the ICU activity scale and the corresponding graded rehabilitation interventions were conducted based on the ICU activity scale. The control group was assessed in accordance with the routine rehabilitation activities, and the postoperative rehabilitation indexes of the patients in both groups were compared (time of tracheal intubation, time of ICU admission, occurrence of complications, and activity scores before ICU transfer). The two groups were compared according to postoperative rehabilitation indicators (time of tracheal intubation, length of ICU stay, and occurrence of complications) and activity scores before ICU transfer.

RESULTS

In the observation group, tracheal intubation time lasted for 18.30 ± 3.28 h and ICU admission time was 4.04 ± 0.83 d, which were significantly shorter than the control group (t-values: 2.97 and 2.038, respectively, P < 0.05). The observation group also had a significantly lower number of complications and adverse events compared to the control group (P < 0.05). Before ICU transfer, the observation group (6.7%) had few complications and adverse events than the control group (30.0 %), and this difference was statistically significant (P < 0.05). Additionally, the activity score was significantly higher in the observation (26.89 ± 0.97) compared to the control groups (22.63 ± 1.12 points) (t-value; -17.83, P < 0.05).

CONCLUSION

Implementation of early goal-directed activities in patients who underwent cardiac surgery using the ICU activity scale can promote the recovery of cardiac function.

Perceived benefits of patient support groups and their format for people with an implantable cardioverter defibrillator

BACKGROUND

Support groups for people with Implantable Cardioverter Defibrillators (ICDs) are widely used, however, it is not clear what people with ICDs gain from a support group or what format they should take.

OBJECTIVES

The aim of the present study is to define the perceived benefit of ICD support groups and develop practical recommendations for group format.

METHODS

14 individuals with ICDs were interviewed using a semi-structured interview guide. Reflexive thematic analysis methods were utilised to code and analyse the transcripts before generating themes.

RESULTS

Four themes were defined: confronting mortality, coping through sharing, coping through learning, and providing space. Making connections with other people with ICDs, reassurance, access to information, and advice from health care professionals were important perceived benefits of the support group.

CONCLUSION

People with ICDs may have to confront their own mortality and adapt to considerable life changes after implant. The findings from the present study have improved understanding of how support groups are perceived and how ICD indication and group format influence the experience. A blended format of in-person community meetings, online forums, HCP-led education and space for person-person interaction is recommended. Importantly, provision of support should not be time-limited to allow people to access it when it most likely to be of benefit to them.

Personal mastery and quality of life in patients with atrial fibrillation after radiofrequency ablation: The mediating role of health promoting behavior

BACKGROUND

Improving quality of life is vital for patients with atrial fibrillation (AF) after radiofrequency ablation. Quality of life can be affected not only by personal mastery but also by health promoting behavior as previously studied. However, it remains unclear whether health promoting behavior mediates the relationship between personal mastery and quality of life.

OBJECTIVES

To explore whether health promoting behavior mediates the relationship between personal mastery and quality of life in patients with AF after radiofrequency ablation.

METHODS

A cross-sectional design and convenience sampling were conducted at a tertiary hospital in China. Self-reported questionnaires were used to assess personal mastery, health promoting behavior and quality of life. SPSS and AMOS software were used for statistical analysis.

RESULTS

A total of 202 patients with AF after radiofrequency ablation were enrolled (mean age 58.28 ± 12.70 years). The scores for personal mastery and quality of life were 22.52 ± 2.53 points and 62.58 ± 8.59 points, respectively, indicating a limited level. The health promoting behavior exhibited a moderate level, with scores averaging 103.82 ± 8.47 points. There was a positive correlation between the three variables (all P < 0.05). Health promoting behavior played a partial mediating role in the relationship between personal mastery and quality of life in patients with AF after radiofrequency ablation, accounting for 44.79 % of the total effect.

CONCLUSIONS

In order to improve quality of life and prognosis, it is necessary to consider enhancing personal mastery and increasing patient compliance with health promoting behavior, which are important ways to improve their quality of life.

Non-pharmacological interventions to reduce thirst in patients with heart failure or hemodialysis: A systematic review and meta-analysis

BACKGROUND

Thirst is a frequent and burdening symptom in many patients, especially in patients with chronic heart failure (CHF) and/or receiving hemodialysis (HD). As drug therapies are not feasible, non-pharmacological strategies are needed to reduce thirst and thirst-related burden.

OBJECTIVES

To identify non-pharmacological interventions aiming to reduce thirst in patients with CHF and/ or HD, to describe intervention components, and to evaluate the effectiveness of these interventions.

METHODS

In February 2024, we completed a systematic search in MEDLINE via PubMed, Livivo, CINAHL, Cochrane Library and Web of Science. Two reviewers independently screened titles, abstracts, and full texts, performed critical appraisal and data extraction. We checked risk of bias with the checklists of the Joanna Briggs Institute and the Cochrane Risk of Bias tool and calculated meta-analyses for sufficiently homogeneous studies using fixed-effects models.

RESULTS

We included 15 intervention studies applying non-pharmacological interventions including chewing gum (n = 8), low-sodium diet (n = 2), acupressure (n = 1), frozen strawberries (n = 1), fluid timetables (n = 1), ice cubes and mouthwash (n = 1), and a psychological intervention (n = 1). Sample sizes varied between 11 and 88 participants. Eleven intervention studies showed a reduction of thirst as intervention effect. Meta-analyses for chewing gum showed no significant effect on thirst using a visual analogue scale (IV: -2,32 [-10.37,5.73]; p = 0.57) or the dialysis thirst inventory (IV: -0.26 [- 1.83, 1.30]; p = 0.74). Quality of studies was moderate to low.

CONCLUSION

Results indicate that various non-pharmacological interventions could be helpful to reduce thirst in patients with CHF or HD, but important uncertainty remains.

The effect of magnesium sulfate on emergence agitation in surgical adult patients undergoing general anesthesia: A systematic review and meta-analysis of randomized controlled trials

STUDY OBJECTIVE

Investigating the effect of magnesium sulfate (MS) on emergence agitation (EA) in adult surgical patients following general anesthesia (GA).

DESIGN

Systematic literature review and meta-analysis (PROSPERO number: CRD42023461988).

SETTING

Review of published literature.

PATIENTS

Adults undergoing GA.

INTERVENTIONS

Intravenous administration of MS.

MEASUREMENTS

We searched PubMed/MEDLINE, EMBASE, the Cochrane Library, Scopus, and Web of Science for publications until September 14, 2023. The primary outcome was the incidence of EA, while the secondary outcomes included the impact of MS on postoperative agitation score (PAS), emergence variables and adverse events. Relative risk (RR) with 95% confidence interval (CI) measured dichotomous outcome, while standardized mean difference (SMD) or mean difference (MD) with 95% CI measured continuous outcomes.

MAIN RESULTS

Meta-analysis of five randomized controlled trials (RCTs) indicated that MS was associated with a lower incidence of EA at various time points (0 min: RR = 0.62, 95% CI [0.41, 0.95]; p = 0.183, I2 = 43.6%; 5 min: RR = 0.29, 95% CI [0.16, 0.52]; p = 0.211, I2 = 36%; 10 min: RR = 0.14, 95% CI [0.06, 0.32]; p = 0.449, I2 = 0%; 15 min: RR = 0.11, 95% CI [0.02, 0.55]; p = 0.265, I2 = 19.5%; 30 min: RR = 0.05, 95% CI [0.00, 0.91]; the postoperative period: RR = 0.21, 95% CI [0.09, 0.49]; p = 0.724, I2 = 0%;). Additionally, MS was associated with a reduced PAS at various time points except for 0 min. However, no significant differences were observed in extubation time, the length of stay in the post-anesthesia care unit, postoperative nausea and vomiting or total complications.

CONCLUSIONS

Limited available evidence suggests that MS was associated with a lower incidence of EA. Nevertheless, further high-quality studies are warranted to strengthen and validate the effect of MS in preventing EA in adult surgical patients.

The knowledge and skills of emergency department registered nursing staff at an academic hospital in South Africa, on endotracheal tube cuff manometry, before and after a training session

Introduction

Accurate management of endotracheal tube cuff pressure is essential to prevent patient morbidity and mortality. Due to increased length of stay of critically ill patients in emergency departments, it has become an increasingly important skill among Emergency Department nurses.

Methods

This prospective longitudinal interventional study was performed among registered nurses at the emergency departments in a Johannesburg Academic Hospital. The study aimed to determine their current knowledge and practical skills on endotracheal tube cuff manometry and assess the effectiveness of a training program. The training program was provided once, in the form of a narrated PowerPoint presentation developed by the researchers and involved theoretical and practical components. The participants' theoretical knowledge and practical skills were measured by using questionnaires and skill assessments. The theoretical and practical scores were compared pre- and post-training.

Results

Of the 63 registered nurses employed in the emergency departments, 95 % (60) participated in this study. 86 % reported having never received any formal training on endotracheal tube cuff manometry. Only 38.9 % used cuff manometry as standard practice and only 12.8 % checked it at appropriate 12-hourly intervals. The pre-training median score on theory was 4.5 (IQR=3.0) and improved to 7.0 (IQR=3.0) post-training. The maximum achievable score was 11 with a pre-training average of 41.8 % and post-training of 64.5 % (p = 0.001).The practical pre-training median score was 1.0 (IQR=8.0) and improved to 12.0 (IQR=2.0) post-training. The maximum achievable score was 12 with a pre-training average of 29.1 % and a post-training average of 93.3 % (p = 0.001).

Conclusion

This study showed inadequate knowledge and skills on endotracheal cuff pressure manometry among registered nurses in the emergency department. It also correlates with other evidence that supports the need for ongoing training programs. Our training program led to significant improvement among participants in both knowledge and practical skills. This training program was well received by participants and deemed to be practice changing. The recommendation after this study will be for South African emergency units to consider using this study and training material as a guide for annual in-service training.

Effectiveness of specialised support surface modes in preventing pressure injuries in intensive care: A systematic review and meta-analysis

BACKGROUND

Patients in intensive care units (ICU) are at an increased risk of pressure injuries. In ICUs, specialised support surfaces are an intervention often used to prevent pressure injuries. This systematic review and meta-analysis aimed to ascertain the effectiveness of different specialised support surface modes for preventing pressure injuries to adult ICU patients.

METHODS

Ovid MEDLINE, Ovid Embase, EBSCO CINAHL, PEDro, Cochrane Library, Clinicaltrials.gov and eligible paper references were searched for appropriate studies. Studies were included if they investigated both dynamic support surface modes low-air-loss (LAL) and alternating pressure (AP), involved adult ICU patients (≥18 years old), and investigated pressure injury incidence. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Mixed Methods Appraisal Tool (MMAT) checklists were used for reporting and quality assessment. Risk ratios (RRs) with 95 % Confidence Intervals (CIs) were used to summarise pressure injury incidence. The pooled RR was calculated with the random-effects model using the Mantel-Haenszel method. Further secondary analysis examined length of stay (LoS) and severity of illness.

RESULTS

The four included studies involved 3,308 patients. These studies were heterogeneous in design. When AP surface mode was compared with LAL surface mode, there was no significant difference in the occurrence of pressure injury (8.9 % versus 10.9 %, RR 0.64). Mattress mode also had no direct association with length of stay and severity of illness.

CONCLUSION

This systematic review and meta-analysis found no significant difference in the effectiveness of LAL and AP support surface modes in preventing pressure injuries in adult ICU patients.

IMPLICATIONS FOR CLINICAL PRACTICE

Clinicians should remember that mattresses are just one element within strategies to prevent pressure injuries in ICUs. The equivocal findings of this systematic review highlight the complexity of preventing pressure injuries and underscore the importance of holistic nursing care.

Performance and validation of two ICU delirium assessment and severity tools; a prospective observational study

BACKGROUND

The clinical statistical performance of the Confusion Assessment Method Intensive Care Unit (CAM-ICU, including CAM-ICU-7) and Intensive Care Delirium Screening Checklist (ICDSC) have rarely been studied. Additionally, delirium severity is often not measured due to a lack of validation of delirium assessment tools.

OBJECTIVE

The aim was to determine the statistical performance of both delirium assessment tools in daily practice, and the correlation with the gold standard Delirium Rating Scale (DRS)-R98, for delirium severity.

RESEARCH METHOD

CAM-ICU-7 and ICDSC, performed by nurses were compared with the DRS-R98 assessed by delirium experts, twice weekly. Within a time-window of one hour all assessments were independently performed.

DESIGN

A prospective observational study performed between October and December 2020.

MAIN OUTCOME MEASURES

Sensitivity, specificity, positive and negative predictive value of both tools was determined. The correlation between DRS-R98 and CAM-ICU-7 and ICDSC was used for validation of delirium severity.

RESULTS

In total, 104 CAM-ICU-7 and 105 ICDSC assessments in 86 patients were compared with the DRS-R98. For the CAM-ICU-7 and ICDSC, respectively, the sensitivity was 90% and 95%, the specificity was 92.4% and 92.3%. The positive predictive value was 0.76 and 0.80, and negative predictive value was 0.77 and 0.97. Correlation of the CAM-ICU-7 score and ICDSC score with the DRS-R98 score was 0.74 (95% CI 0.64-0.81) and 0.70 (95%CI 0.59-0.79; both p < 0.001), respectively.

CONCLUSION

Both CAM-ICU-7 and ICDSC demonstrated good statistical performance and correlated well with the delirium severity tool DRS-R98.

IMPLICATIONS FOR CLINICAL PRACTICE

Nurses can either use the CAM-ICU(-7) or the ICDSC in their practice, both are accurate in delirium diagnosis. Total CAM-ICU-7 and ICDSC score reflects delirium severity well; the higher the score, the more severe the delirium. This enables nurses to gauge the impact of their interventions and enhance the well-being of patients experiencing delirium by minimizing distressing occurrences.

Tools used to assess comfort among patients undergoing high flow nasal cannula: A scoping review

OBJECTIVE

The aims were twofold: (a) to map tools documented in the literature to evaluate comfort among patients undergoing high flow nasal cannula (HFNC) treatment; and (b) to assess if the retrieved tools have been validated for this purpose.

METHODS

A scoping review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). In July 2023, PubMed, Scopus, CINAHL and Cochrane Library were consulted. Studies assessing comfort in adult, paediatric, and neonatal patients undergoing HFNC were included.

RESULTS

Seventy-four articles were included, among which nine (12.2 %) investigated comfort as the primary aim. Twenty-five different tools were found, classifiable into 14 types, mostly unidimensional and originating from those measuring pain. The most widely used was the Visual Analogic Scale (n = 27, 35.6 %) followed by the Numerical Rating Scale (n = 11, 14.5 %) and less defined generic tools (n = 10, 13.2 %) with different metrics (e.g. 0-5, 0-10, 0-100). Only the General Comfort Questionnaire and the Comfort Scale were specifically validated for the assessment of comfort among adults and children, respectively.

CONCLUSION

Although the comfort of patients undergoing HFNC is widely investigated in the literature, there is a scarcity of tools specifically validated in this field. Those used have been validated mainly to assess pain, suggesting the need to inform patients to prevent confusion while measuring comfort during HFNC and to develop more research in the field.

IMPLICATIONS FOR CLINICAL PRACTICE

Comfort assessment is an important aspect of nursing care. Given the lack of validation studies in the field, efforts in research are recommended.

Combining the Nurse Intuition Patient Deterioration Scale with the National Early Warning Score provides more Net Benefit in predicting serious adverse events: A prospective cohort study in medical, surgical, and geriatric wards

OBJECTIVES

This prospective cohort study aimed to assess the predictive value of the Nurse Intuition Patient Deterioration Scale (NIPDS) combined with the National Early Warning Score (NEWS) for identifying serious adverse events in patients admitted to diverse hospital wards.

RESEARCH METHODOLOGY/DESIGN

Data was collected between December 2020 and February 2021 in a 350-bed acute hospital near Brussels, Belgium. The study followed a prospective cohort design, employing NIPDS alongside NEWS for risk assessment. Patients were monitored for 24 h post-registration, with outcomes recorded.

SETTING

The study was conducted in a hospital with a Rapid Response System (RRS) and electronic patient record wherein NEWS was routinely collected. Patients admitted to two medical, two surgical, and two geriatric wards were included.

MAIN OUTCOME MEASURES

The primary outcome included death, urgent code calls, or unplanned ICU transfers within 24 h after NIPDS registration. The secondary outcome comprised rapid response team activations or changes in Do-Not-Resuscitate codes.

RESULTS

In a cohort of 313 patients, 10/313 and 31/313 patients reached the primary and secondary outcome respectively. For the primary outcome, NIPDS had a sensitivity of 0.900 and specificity of 0.927, while NEWS had a sensitivity of 0.300 and specificity of 0.974. Decision Curve Analysis demonstrated that NIPDS provided more Net Benefit across various Threshold Probabilities. Combining NIPDS and NEWS showed potential for optimizing rapid response systems. Especially in resource-constrained settings, NIPDS could be used as a calling criterion.

CONCLUSION

The NIPDS displayed strong predictive capabilities for adverse events. Integrating NIPDS into existing rapid response systems can objectify nurse intuition, enhancing patient safety.

IMPLICATIONS FOR CLINICAL PRACTICE

The Nurse Intuition Patient Deterioration Scale (NIPDS) is a valuable tool for detecting patient deterioration. Implementing NIPDS alongside traditional scores such as NEWS can improve patient care and safety. The optimal NIPDS threshold to activate rapid response is ≥5.

Barriers and facilitators of adherence to evidence-based pressure injury prevention clinical practice guideline among intensive care nurses: A cross-sectional survey

OBJECTIVE

To explore intensive care unit (ICU) nurses' perceptions of their adherence to pressure injury prevention clinical practice guideline and identify the perceived barriers and facilitators that influence evidence-based pressure injury prevention practices in Chinese tertiary hospitals.

RESEARCH METHODOLOGY/DESIGN

This was a multi-site, quantitative, cross-sectional study. Data were collected using a self-report questionnaire with three sections: participant demographic information, adherence to pressure injury prevention clinical practice guideline, and barriers to and facilitators of pressure injury prevention clinical practice guideline implementation.

SETTING

Thirty-three adult ICUs in 16 tertiary general hospitals in 5 major cities in Liaoning Province, China.

RESULTS

In total, 473 nurses responded to the survey. The mean score for adherence to pressure injury prevention clinical practice guideline was 159.06 ± 20.65, with 65.3 % reporting good adherence. Multiple stepwise regression analysis indicated that smaller ICU size (β = -0.114, p = 0.012) and having participated in training on pressure injury prevention clinical practice guideline (β = 0.149, p = 0.001) were statistically significantly associated with better adherence. ICU nurses identified the low priority given to pressure injury prevention as the top barrier. The top three facilitators were awareness of evidence-based practice, the current documentation format for pressure injury risk/nursing interventions, and leadership support.

CONCLUSION

ICU nurses' adherence to pressure injury prevention clinical practice guideline was satisfactory, and they reported low-to-moderate barriers and moderate facilitators.

IMPLICATIONS FOR CLINICAL PRACTICE

Participating in training on pressure injury prevention clinical practice guideline was a predictor of ICU nurses' adherence. Therefore, it is highly recommended that healthcare organisations consider providing training to nurses and address the barriers identified to improve nurses' adherence to evidence-based pressure injury prevention guidelines.

Albumin: a comprehensive review and practical guideline for clinical use

PURPOSE

Nowadays, it is largely accepted that albumin should not be used in hypoalbuminemia or for nutritional purpose. The most discussed indication of albumin at present is the resuscitation in shock states, especially distributive shocks such as septic shock. The main evidence-based indication is also liver disease. In this review, we provided updated evidence-based instruction for definite and potential indications of albumin administration in clinical practice, with appropriate dosing and duration.

METHODS

Data collection was carried out until November 2023 by search of electronic databases including PubMed, Google Scholar, Scopus, and Web of Science. GRADE system has been used to determine the quality of evidence and strength of recommendations for each albumin indication.

RESULTS

A total of 165 relevant studies were included in this review. Fluid replacement in plasmapheresis and liver diseases, including hepatorenal syndrome, spontaneous bacterial peritonitis, and large-volume paracentesis, have a moderate to high quality of evidence and a strong recommendation for administering albumin. Moreover, albumin is used as a second-line and adjunctive to crystalloids for fluid resuscitation in hypovolemic shock, sepsis and septic shock, severe burns, toxic epidermal necrolysis, intradialytic hypotension, ovarian hyperstimulation syndrome, major surgery, non-traumatic brain injury, extracorporeal membrane oxygenation, acute respiratory distress syndrome, and severe and refractory edema with hypoalbuminemia has a low to moderate quality of evidence and weak recommendation to use. Also, in modest volume paracentesis, severe hyponatremia in cirrhosis has a low to moderate quality of evidence and a weak recommendation.

CONCLUSION

Albumin administration is most indicated in management of cirrhosis complications. Fluid resuscitation or treatment of severe and refractory edema, especially in patients with hypoalbuminemia and not responding to other treatments, is another rational use for albumin. Implementation of evidence-based guidelines in hospitals can be an effective measure to reduce inappropriate uses of albumin.

Factors that influence critical care nurses' management of sedation for ventilated patients in critical care: A qualitative study

BACKGROUND

Optimising sedation use is key to timely extubation. Whilst sedation protocols may be used to guide critical care nurses' management of sedation, sedation management and decision-making is complex, influenced by multiple factors related to patients' circumstances, intensive care unit design and the workforce.

AIM

To explore (i) critical care nurses' experiences managing sedation in mechanically ventilated patients and (ii) the factors that influence their sedation-related decision-making.

DESIGN

Qualitative descriptive study using semi-structured interviews. Data were analysed using Braun and Clarke's six-step thematic analysis.

SETTING AND PARTICIPANTS

This study was conducted in a 26-bed level 3 accredited ICU, in a private hospital in Melbourne, Australia. The majority of patients are admitted following elective surgery. Critical care nurses, who were permanently employed as a registered nurse, worked at least 16 h per week, and cared for ventilated patients, were invited to participate.

FINDINGS

Thirteen critical care nurses participated. Initially, participants suggested their experiences managing sedation were linked to local unit policy and learning. Further exploration revealed that experiences were synonymous with descriptors of factors influencing sedation decision-making according to three themes: (i) Learning from past experiences, (ii) Situational awareness and (iii) Prioritising safety. Nurses relied on their cumulative knowledge from prior experiences to guide decision-making. Situational awareness about other emergent priorities in the unit, staffing and skill-mix were important factors in guiding sedation decision-making. Safety of patients and staff was essential, at times overriding goals to reduce sedation.

CONCLUSION

Sedation decision making cannot be considered in isolation. Rather, sedation decision making must take into account outcomes of patient assessment, emergent priorities, unit and staffing factors and safety concerns.

IMPLICATIONS FOR CLINICAL PRACTICE

Opportunities for ongoing education are essential to promote nurses' situational awareness of other emergent unit priorities, staffing and skill-mix, in addition to evidence-based sedation management and decision making.

A scoping review of incidence and assessment tools for post-intensive care syndrome following cardiac surgery

BACKGROUND

Post-intensive care syndrome is a new or worsening persistent deterioration in cognitive, mental, and/or physical health following a prolonged admission to an intensive care unit. Post-intensive care syndrome remains underexplored following cardiac surgery, with a lack of understanding of the incidence and tools used to measure the symptoms. A scoping review was conducted to determine the incidence and to identify the tools commonly used to measure symptoms of post-intensive care syndrome following cardiac surgery.

METHODS

The electronic databases Medline (Ovid), EMBASE (Ovid), PsycINFO (Ovid), Scopus, and CINAHL (EBSCOhost) and Google Scholar were searched with keywords and controlled vocabulary to describe both cardiac surgery and post-intensive care syndrome (cardiac surgical procedures, heart surgery, and post-intensive care symptoms) and symptoms (delirium, depression, mobility and quality of life). Included were articles written in English and published after 2005 that described cognitive, mental, and physical symptoms of post-intensive care syndrome following cardiac surgery. 3,131 articles were found, with 565 duplicates, leaving 2,566 articles to be screened. Of these, seven unique studies were included.

RESULTS

Five studies explored cognitive health, three mental health, one cognitive and mental health, and none physical health. No identified studies reported the overall incidence of post-intensive care syndrome following cardiac surgery. The incidence of cognitive health issues ranged from 21% to 38%, and mental health issues ranged from 16% to 99%. In total, 17 different tools were identified - 14 for cognitive health and three for mental health. No identified studies used the same tools to measure symptoms. No single tool was found to measure all three domains.

CONCLUSION

This scoping review identified a literature gap specific to the incidence and inconsistency of assessment tools for post-intensive care syndrome in cardiac surgery patients.

CLINICAL IMPLICATIONS

This work impacts clinical practice for the bedside nurse by raising awareness of an emerging health issue.

An integrative literature review of factors contributing to hypothermia in adults during the emergent (ebb) phase of a severe burn injury

BACKGROUND

During the emergent (ebb) phase (first 72 h), the adult person with a severe burn experiences loss of body heat, decreased metabolism, and poor tissue perfusion putting them at risk of hypothermia, increased morbidity, and mortality. Therefore, timely and targeted care is imperative.

AIM

The aim of this integrative literature review was to develop a framework of the factors contributing to hypothermia in adults with a severe burn injury during the emergent (ebb) phase.

METHODS

An integrative review of research literature was undertaken as it provides an orderly process in the sourcing and evaluation of the literature. Only peer reviewed research articles, published in scholarly journals were selected for inclusion (n = 26). Research rigor and quality for each research article was determined using JBI Global appraisal tools relevant to the methodology of the selected study.

FINDINGS

Contributing factors were classified under three key themes: Individual, Pre-hospital, and In-hospital factors.

CONCLUSION

The structured approach enabled the development of an evidence-based framework identifying factors contributing to hypothermia in adults with a severe burn injury during the emergent (ebb) phase and adds knowledge to improve standardized care of the adult person with a severe burn injury.

Metabolic support for patients on extra-corporeal membrane oxygenation

PURPOSE OF REVIEW

The purpose of the review is to summarize recent research on metabolic support during extracorporeal membrane oxygenation. In this review, we cover the evidence on nutritional supplementation, both the route of supplementation, timing of initiation of supplementation as well as quantities of supplementation needed. In addition, we discuss the recent trend in awake extracorporeal membrane oxygenation (ECMO) and its benefits to patients.

RECENT FINDINGS

As ECMO use continues to increase over the last few years, for both cardiovascular as well as respiratory failure, the need to optimize the metabolic states of patients has arisen. Increasing evidence has pointed towards this hitherto unexplored domain of patient care having a large impact on outcomes. Additionally, strategies such as awake ECMO for select patients has allowed them to preserve muscle mass which could aid in a faster recovery.

SUMMARY

There is a role of optimal metabolic support in the early recovery of patients on ECMO that is currently under-recognized. Future directions of research that aim to improve post ECMO outcomes must focus on this area.

Light, sleep and circadian rhythm in critical illness

PURPOSE OF REVIEW

Sleep and circadian disruption (SCD) are associated with worse outcomes in the ICU population. We discuss sleep, circadian physiology, the role of light in circadian entrainment and its possible role in treating SCD, with special attention to the use of light therapies and ICU design.

RECENT FINDINGS

The American Thoracic Society recently published an official research statement highlighting key areas required to define and treat ICU SCD. Recent literature has been predominantly observational, describing how both critical illness and the ICU environment might impair normal sleep and impact circadian rhythm. Emerging consensus guidance outlines the need for standardized light metrics in clinical trials investigating effects of light therapies. A recent proof-of-concept randomized controlled trial (RCT) showed improvement in delirium incidence and circadian alignment from ICU room redesign that included a dynamic lighting system (DLS).

SUMMARY

Further investigation is needed to define the optimal physical properties of light therapy in the ICU environment as well as timing and duration of light treatments. Work in this area will inform future circadian-promoting design, as well as multicomponent nonpharmacological protocols, to mitigate ICU SCD with the objective of improving patient outcomes.

Psychometric properties of the Braden scale to assess pressure injury risk in intensive care: A systematic review

OBJECTIVE

To analyse the psychometric properties of the Braden scale to assess pressure injury risk in adults in intensive care.

DESIGN

A systematic review was conducted, with literature searches undertaken in five electronic databases. No date limits were applied. Selection, data extraction and risk of bias assessment were completed by two reviewers independently. A customised data extraction template was used, with risk of bias conducted using the COSMIN Risk of Bias checklist. Data were analysed using narrative synthesis.

RESULTS

Thirty-four studies met inclusion criteria. Two studies reported internal consistency with Cronbach's alpha ranging from poor (0.43) to good (0.85). For interrater reliability, only four studies reported intraclass correlation, ranging from 0.66 to 0.96 for Braden sum score. Three studies reported convergent validity, with strong associations found between the COMHON Index (r = 0.70), Cubbin-Jackson scale (r = 0.80), and Norton scale (r = 0.77), but contrasting associations with the Waterlow score (r = 0.22 to 0.72). A large majority of studies reported predictive validity (n = 29), with wide variability. Several studies investigated optimal cut-off scores, with the majority indicating this was in the range of 12-14.

CONCLUSIONS

This review demonstrates inconsistency in the psychometric properties of the Braden scale in ICU settings. Further research is needed to determine suitability of the Braden scale for ICU before it can be recommended as standard for clinical practice, including comparison with other ICU-specific risk assessment tools.

IMPLICATIONS FOR CLINICAL PRACTICE

When used in ICU, the reliability, validity and reported cut-off scores of the Braden scale are variable. As a predictive tool, the scale should be used cautiously. In ICU, the value of the Braden scale resides in its ability to identify patients that are most at risk of developing a pressure injury and to implement preventative measures to mitigate identified risk factors.

Supporting rural families during interhospital patient transfers for critical illness events: An exploration of an acceptable communication process

Critically ill patients in rural areas at times require an interhospital transfer from their local hospital to an urban tertiary care centre for advanced critical care services not available locally. Family members have described this transfer window as a communication blackout and one of the most stressful times of their relative's critical illness event.

OBJECTIVE

To explore what communication process would be most acceptable between family members and transfer team members (consisting of critical care nurses, paramedics, and physicians) during interhospital transfers of critically ill patients.

RESEARCH METHODOLOGY

Using a qualitative descriptive approach of critical thematic analysis, data were collected in September and November 2022, from focus groups of five family members and four transfer team members who experienced this phenomenon.

SETTING

Rural Canada where speciality services such as interventional cardiology and neurosurgery are unavailable, and a tertiary care hospital is more than 160 km away.

FINDINGS

Within themes of unequal power relations and status-based hierarchies, family members described how communication during interhospital transfers supports connection and coping, challenges experienced in accessing information, an overwhelming unknown, and practical challenges of the transfer. Transfer team members described a context of power relations and status-based hierarchies in which themes of transfer team burden, role confusion or connection, protection and management of family members, and complexities of information sharing during interhospital transfers were identified.

CONCLUSION

In critical illness, communication linkages are created between healthcare providers and family members but are broken during an interhospital transfer resulting in increased stress for family members. Acceptable communication elements described by transfer team members and family members may maintain these linkages during the transfer window.

IMPLICATIONS FOR CLINICAL PRACTICE

These findings provide the foundation for critical care nurses and their professional colleagues to take family care to the next level with an explicit communication strategy during interhospital transfers.

Postextubation dysphagia management in Danish intensive care units: A national survey

BACKGROUND

Postextubation dysphagia (PED) is a common complication to endotracheal intubation in critically ill patients and may lead to pneumonia, prolonged ventilation, longer hospital stays, and increased mortality. Recognizing dysphagia is paramount to preventing adverse events. The aim of this study was to describe PED management by investigating practice in Danish intensive care units (ICUs) focusing on current practice in 2023 (screening, prevention, and treatment), perceived best practice (barriers and facilitators), and when possible, to compare practice in 2017 and 2023.

METHODS

Self-reported, cross-sectional survey of dysphagia practice in Danish ICUs administered from April to May 2023. In addition, data were compared with the 2017 Dysphagia in Intensive Care Evaluation study, when possible.

RESULTS

Only half of Danish ICUs reported to have a PED protocol, and less than half routinely screen patients for dysphagia after extubation. Most common screening methods were the oral mechanism examination, water test, and Facio-oral tract therapy. Nurses and physicians often relied on an overall physical assessment of the patient. Best treatment methods were uniformly agreed to be patient positioning, modification of food and fluids, use of ergonomic utensils, and compensatory maneuvers. Key barriers to dysphagia management were lack of specialized staff, under-recognition of dysphagia as a health issue, and lack of standardized protocols.

CONCLUSION

Awareness of PED is increasing and identification, prevention, and treatment is slowly improving, but systematic implementation of protocols for dysphagia screening and treatment could enhance dysphagia management in Danish ICUs.

Impact of the health policy for interdisciplinary collaborative rehabilitation practices in intensive care units: A difference-in-differences analysis in Japan

BACKGROUND

Early rehabilitation in intensive care units (ICUs) may be beneficial but is not routinely performed for adults with critical illness. In April 2018, the Japanese government introduced a health policy to provide financial incentives to hospitals that met the requirements of interdisciplinary collaboration and had teams specialized in ICU rehabilitation practices.

OBJECTIVES

The present study aimed to investigate whether the health policy is associated with improved clinical practices of ICU rehabilitation.

METHODS

Using a nationwide administrative inpatient database and hospital statistics data from Japan, we identified hospitals that admitted adult patients to the ICU within two days of hospital admission from April 2016 to March 2019. Using hospital-level propensity score matching, we created matched cohorts of 101,203 patients from 108 intervention hospitals that introduced the health policy, and 106,703 patients from 108 control hospitals that did not. We then conducted patient-level difference-in-differences analyses to examine changes in the percentage of patients from the intervention and control hospitals, who underwent early ICU rehabilitation within two days of ICU admission before and after the implementation of the health policy.

RESULTS

In the intervention group, patients undergoing early ICU rehabilitation increased from 10% and 36% after the policy implementation. In the control group, it increased from 11% to 13%. The difference-in-difference in the percentage of patients who underwent early ICU rehabilitation between the two groups was 24% (95% confidence interval, 19%-29%).

CONCLUSIONS

Early ICU rehabilitation can be facilitated by financial incentives for hospitals that engage in interdisciplinary collaboration with specialist teams.

IMPLICATIONS FOR CLINICAL PRACTICE

Our Findings are relevant for hospital administrators, professional organizations, and policymakers in other nations considering strategies to support the additional deployment burdens of early ICU rehabilitation. Future studies need to explore the long-term effects and sustainability of the observed improvements in ICU rehabilitation practices.

Facilitators, barriers and acceptability of implementing a communication board in Sri Lankan intensive care units: A qualitative descriptive study

OBJECTIVES

To explore patients' and nurses' views of potential facilitators, barriers, and prospective acceptability of implementing a communication board in Sri Lankan intensive care units.

DESIGN

A qualitative, descriptive study.

RESEARCH METHODOLOGY

Eight patients who received mechanical ventilation and nine nurses who worked in adult medical and surgical intensive care units were purposively selected. Data were collected via audio-taped, semi-structured, face-to-face interviews in January/February 2023. Interview guide questions were informed by the knowledge-to-action framework and the theoretical framework of acceptability. Data were analysed using inductive and deductive content analysis. The 32-item checklist of the consolidated criteria for reporting qualitative research (COREQ) was used to ensure the quality of reporting.

SETTING

A 3,000 bed Sri Lankan teaching hospital with 18 intensive care units.

FINDINGS

Four categories reflecting patients' and nurses' anticipated use of the board were found. The first category described patients' and nurses' 'readiness to use the communication board' and their positive attitudes towards it. The second category focused on the 'potential benefits of the communication board', while the third category emphasised the 'individual patient characteristics' that should be taken into consideration when implementing communication boards. The final category described practical aspects related to 'integrating communication boards into routine practice'.

CONCLUSION

This study demonstrates communication boards may improve communication between ventilated patients and nurses, and they are acceptable to end users. Adopting these tools may be a pivotal step to enhancing patient-centred care in demanding intensive care settings.

IMPLICATIONS FOR CLINICAL PRACTICE

An inability to communicate effectively with ventilated intensive care patients creates negative experiences for both patients and nurses. Communication boards may act as a medium to better understand patients' needs during mechanical ventilation.Understanding patients' and nurses' views is beneficial when designing patient-centred communication interventions in intensive care units.

Progress in the validation of nociception monitoring in guiding intraoperative analgesic therapy

PURPOSE OF REVIEW

This article summarizes the current level of validation for several nociception monitors using a categorized validation process to facilitate the comparison of performance.

RECENT FINDINGS

Nociception monitors improve the detection of a shift in the nociception and antinociception balance during anesthesia, guiding perioperative analgesic therapy. A clear overview and comparison of the validation process for these monitors is missing.

RESULTS

Within a 2-year time-frame, we identified validation studies for four monitors [analgesia nociception index (ANI), nociception level monitor (NOL), surgical pleth index (SPI), and pupillometry]. We categorized these studies in one out of six mandatory validation steps: developmental studies, clinical validation studies, pharmacological validation studies, clinical utility studies, outcome improvement studies and economical evaluation studies. The current level of validation for most monitors is mainly focused on the first three categories, whereas ANI, NOL, and SPI advanced most in the availability of clinical utility studies and provide confirmation of a clinical outcome improvement. Analysis of economical value for public health effects is not yet publicly available for the studied monitors.

SUMMARY

This review proposes a stepwise structure for validation of new monitoring technology, which facilitates comparison between the level of validation of different devices and identifies the need for future research questions.

Pressure ulcer risk assessment in the ICU. Is it time for a more objective measure?

BACKGROUND

The Braden scale, one of the most widely used risk assessment tools is often criticized when used in the Intensive Care Unit. Most patients in the Intensive Care Unit are at risk of pressure ulcer development meaning that the Braden score will usually indicate high risk for these patients. This study set out to determine the correlation between Sub-Epidermal Moisture measurements and Braden scores among Intensive Care Unit patients.

METHODS

This study employed an observational research design. Braden score was assessed on all study days (1-5), in addition to visual skin assessment and Sub-Epidermal Moisture measurements at the sacrum and heels. Sub-Epidermal Moisture measurements were categorised as low (<0.5), borderline abnormal (≥0.5), and high (≥0.8). Correlation was assessed between Sub-Epidermal Moisture levels and Braden scores.

RESULTS

A total of 53 participants were recruited. The median (interquartile range) baseline Braden score was 9 (9-10) and 81 % (n = 43) of participants were at very high/high risk of pressure ulcer development. Braden scores remained relatively constant over time with little fluctuation in scores. 19 % (n = 10) of patients had normal (<0.5) Sub-Epidermal Moisture delta measurements on enrolment, and all developed abnormal measurements by day 2. There were no significant correlations between Braden scores and Sub-Epidermal Moisture measurements.

CONCLUSION

Although this was not its original intention, a missing link with the Braden scale is that it does not provide information on how patients are responding to the adverse effects of pressure and shear forces. Furthermore, in patients who are critically unwell, most patients are classified as being "at risk" of pressure ulcer development. Therefore, an objective measure of how patients are responding to pressure and shear forces at different anatomical areas is needed.

IMPLICATIONS TO CLINICAL PRACTICE

Sub-Epidermal Moisture measurements can offer more information, not only on identifying those who are at risk, but also how those patients are tolerating this risk at different anatomical sites.

Does pre-injury anticoagulation make chest tubes any less safe? A nationwide retrospective analysis

BACKGROUND

Oral anticoagulation is becoming more common with the aging population, which raises concern for the risk of invasive procedures that can cause bleeding, such as chest tube placement (thoracostomy). With the increase in CT imaging, more pneumothoraces and hemothoraces are being identified. The relative risk of thoracostomy in the presence of anticoagulation is not well-established. The objective of this study was to determine whether pre-injury anticoagulation affects the relative risk of tube thoracostomy following significant chest trauma.

METHODS

This retrospective cohort study used data from the 2019 American College of Surgeons-Trauma Quality Program (ACS-TQP) database using R version 4.2.2. Data from the database was filtered based on inclusion and exclusion criteria. Outcomes were then assessed with the population of interest. Demographics, vitals, comorbidities, and injury parameters were also collected for each patient. This study included all adult patients (≥18 years) presenting with traumatic hemothorax, pneumothorax, or hemopneumothorax. Patients with missing data in demographics, vitals, comorbidities, injury parameters, or outcomes, as well as those with no signs of life upon arrival, were excluded from the study. Patients were stratified into groups based on whether they had pre-injury anticoagulation and whether they had a chest tube placed in the hospital. The primary outcome was mortality, and the secondary outcome was hospital length of stay (LOS). Logistic and standard regressions were used by a statistician to control for age, sex, and Injury Severity Score (ISS).

RESULTS

Our study population included 72,385 patients (4250 with pre-injury anticoagulation and 68,135 without pre-injury anticoagulation). Pre-injury anticoagulation and thoracostomy were each independently associated with increased mortality and LOS. However, there was a non-significant interaction term between pre-injury anticoagulation and thoracostomy for both outcomes, indicating that their combined effects on mortality and LOS did not differ significantly from the sum of their individual effects.

CONCLUSION

This study suggests that both pre-injury anticoagulation and thoracostomy are risk factors for mortality and increased LOS in adult patients presenting with hemothorax, pneumothorax, or hemopneumothorax, but they do not interact with each other. We recommend further study of this phenomenon to potentially improve clinical guidelines.

LEVEL OF EVIDENCE

Therapeutic, Level III.

Design and content validation of a checklist about infection-prevention performance of intensive care nurses in simulation-based scenarios

OBJECTIVE

To design, develop and validate a new tool, called NEUMOBACT, to evaluate critical care nurses' knowledge and skills in ventilator-associated pneumonia (VAP) and catheter-related bacteraemia (CRB) prevention through simulation scenarios involving central venous catheter (CVC), endotracheal suctioning (ETS) and mechanically ventilated patient care (PC) stations.

BACKGROUND

Simulation-based training is an excellent way for nurses to learn prevention measures in VAP and CRB.

DESIGN

Descriptive metric study to develop NEUMOBACT and analyse its content and face validity that followed the COSMIN Study Design checklist for patient-reported outcome measurement instruments.

METHODS

The first version was developed with the content of training modules in use at the time (NEUMOBACT-1). Delphi rounds were used to assess item relevance with experts in VAP and CRB prevention measures, resulting in NEUMOBACT-2. Experts in simulation methods then assessed feasibility, resulting in NEUMOBACT-3. Finally, a pilot test was conducted among 30 intensive care unit (ICU) nurses to assess the applicability of the evaluation tool in clinical practice.

RESULTS

Seven national experts in VAP and CRB prevention and seven national simulation experts participated in the analysis to assess the relevance and feasibility of each item, respectively. After two Delphi rounds with infection experts, four Delphi rounds with simulation experts, and pilot testing with 30 ICU nurses, the NEUMOBACT-FINAL tool consisted of 17, 26 and 21 items, respectively, for CVC, ETS and PC.

CONCLUSION

NEUMOBACT-FINAL is useful and valid for assessing ICU nurses' knowledge and skills in VAP and CRB prevention, acquired through simulation.

RELEVANCE FOR CLINICAL PRACTICE

Our validated and clinically tested tool could facilitate the transfer of ICU nurses' knowledge and skills learning in VAP and CRB prevention to critically ill patients, decreasing infection rates and, therefore, improving patient safety.

PATIENT OR PUBLIC CONTRIBUTION

Experts participated in the Delphi rounds and nurses in the pilot test.

Outcomes associated with ventilator-associated events (VAE), respiratory infections (VARI), pneumonia (VAP) and tracheobronchitis (VAT) in ventilated pediatric ICU patients: A multicentre prospective cohort study

OBJECTIVES

An objective categorization of respiratory infections based on outcomes is an unmet clinical need. Ventilator-associated pneumonia and tracheobronchitis remain used in clinical practice, whereas ventilator-associated events (VAE) are limited to surveillance purposes.

RESEARCH METHODOLOGY/DESIGN

This was a secondary analysis from a multicentre observational prospective cohort study. VAE were defined as a sustained increase in minimum Oxygen inspired fraction (FiO2) and/or Positive end-expiratory pressures (PEEP) of ≥ 0.2/2 cm H2O respectively, or an increase of 0.15 FiO2 + 1 cm H20 positive end-expiratory pressures for ≥ 1 calendar-day.

SETTING

15 Paediatric Intensive Care Units.

MAIN OUTCOME MEASURES

Mechanical ventilation duration, intensive care and hospital length of stay; (LOS) and mortality.

RESULTS

A cohort of 391 ventilated children with an age (median, [Interquartile Ranges]) of 1 year[0.2-5.3] and 7 days[5-10] of mechanical ventilation were included. Intensive care and hospital stays were 11 [7-19] and 21 [14-39] days, respectively. Mortality was 5.9 %. Fifty-eight ventilator-associated respiratory infections were documented among 57 patients: Seventeen (29.3 %) qualified as ventilator-associated pneumonia (VAP) and 41 (70.7 %) as ventilator-associated tracheobronchitis (VAT). Eight pneumonias and 16 tracheobronchitis (47 % vs 39 %,P = 0.571) required positive end-expiratory pressure or oxygen increases consistent with ventilator-associated criteria. Pneumonias did not significantly impact on outcomes when compared to tracheobronchitis. In contrast, infections (pneumonia or tracheobronchitis) following VAEs criteria were associated with > 6, 8 and 15 extra-days of ventilation (16 vs 9.5, P = 0.001), intensive care stay (23.5 vs 15; P = 0.004) and hospital stay (39 vs 24; P = 0.015), respectively.

CONCLUSION

When assessing ventilated children with respiratory infections, VAE apparently is associated with higher ventilator-dependency and LOS compared with pneumonia or tracheobronchitis.

IMPLICATIONS FOR PRACTICE

Incorporating the modification of ventilatory settings for further categorization of the respiratory infections may facilitate therapeutic management among ventilated patients.

Intention to use physical restraint in paediatric intensive care units and correlated variables: A multicentre and cross-sectional study

OBJECTIVES

To determine the intention to use physical restraint (PR) and the relationship with sociodemographic and professional variables of the Paediatric Intensive Care Unit (PICU) nurses.

RESEARCH METHODOLOGY/DESIGN AND SETTING

A multicentre and correlational study was carried out from October 2021 to December 2023 in five paediatric intensive care units from five maternal and child hospitals in Spain. The Paediatric Physical Restraint-Theory of Planned Behaviour Questionnaire was provided. Moreover, sociodemographic and employment variables were registered.

RESULTS

A total of 230 paediatric nurses participated in the study. A total of 87.7 % were females with an average age of 35.5 ± 9.7 years and working experience of 10.5 ± 8.4 years. The mean scores obtained were 21.1 ± 3.8 for attitude, 13.1 ± 5.0 for subjective norms, 14.4 ± 4.3 for perceived behavioural control and 28.0 ± 6.0 for intention. The nurses apply more physical restraint to anxious patients, with scarce analgesics and sedation, those affected with pharmacological withdrawal symptoms and those with a high risk of accidental removal of vital support devices or fall from bed. The sex (p = 0.007) and type of employment contract (p = 0.01) are the variables that are significantly correlated with the intention to use of PR.

CONCLUSION

The paediatric nurses analysed had a moderate attitude, social pressure and perceived behavioural control towards the use of PR.

IMPLICATIONS FOR CLINICAL PRACTICE

It is important to know the factors that influence the intention to use physical restraint in order to standardise safe practice for critically ill paediatric and to ensure that patients' rights are respected by obtaining informed consent and assessing the prescription, continuation and removal of physical restraint.

Assessment of pressure injury risk in intensive care using the COMHON index: An interrater reliability study

OBJECTIVES

To assess the interrater reliability of the COMHON (level of COnciousness, Mobility, Haemodynamics, Oxygenation, Nutrition) Index pressure injury risk assessment tool.

DESIGN

Interrater reliability was tested. Twenty-five intensive care patients were each assessed by five different nurse-raters from a pool of intensive care nurses who were available on the days of assessment. In total, 25 nurses participated.

SETTING

Two general and one cardiovascular surgery intensive care units in Istanbul, Turkey.

MAIN OUTCOME MEASURES

Interrater reliability was analysed using intraclass correlations, and standard errors of measurement (SEM) were calculated for sum scores, risk level and item scores. Minimally detectable change (MDC) was also calculated for sum score. Consistency between paired raters was analysed using Pearson's Product Moment Correlation (r) for sum score and Spearman's rho (rs) for ordinal variables.

RESULTS

All assessments were completed in ≤5 min. Interrater reliability was very high [ICC (1,1) = 0.998 (95 % CI 0.996 - 0.999)] with a SEM of 0.14 and MDC of 0.39. Consistency between paired raters was strong for sum and item scores and risk levels (coefficients >0.6). All scale items showed correlations of >.3 with the sum score.

CONCLUSION

The results demonstrate near-perfect interrater reliability. Further research into the psychometric properties of the COMHON Index and its impact on preventative intervention use is warranted.

IMPLICATIONS FOR CLINICAL PRACTICE

Pressure injury risk assessment within intensive care should be setting-specific due to the unique risk factors inherent to the patient population, which are not considered by general pressure injury risk assessment tools. An intensive care-specific pressure injury risk assessment tool was tested and demonstrated high reliability between intensive care nurses. Further research is needed to understand how its use in practice affects preventative intervention implementation and, in turn, how it impacts pressure injury outcomes.

What can be done about workplace wellbeing in emergency departments? 'There's no petrol for this Ferrari'

Workplace wellbeing encompasses all aspects of working life. Peak health organisations recognise that poor workplace wellbeing is costly, both to individuals and to the organisation, and the value in promoting healthy workplaces. Workplace wellbeing improves when its barriers are acknowledged and addressed, and protective factors are promoted. The Emergency Department (ED) is a place of intense and challenging activity, exacerbated by high workloads and overcrowding. This impacts negatively on patient care, staff safety and wellbeing. We held focus groups across four EDs to discuss barriers and enablers to wellbeing and found four core themes: Workplace Satisfaction; Barriers to Wellbeing; Organisational Culture that Prioritises Staff Wellbeing; Self-care and Self Compassion. From this, and existing literature, we collaboratively developed a contextualised staff wellbeing framework titled: 'Staff Wellbeing Good Practice Framework: From Surviving to Thriving, How to Protect your Wellbeing in the Emergency Department' that emphasises their values of Competence, Connection and Control.

Nutrition during noninvasive respiratory support

PURPOSE OF REVIEW

The use of noninvasive techniques [noninvasive ventilation (NIV) or high flow nasal cannula (HFNC) oxygen therapy] to support oxygenation and/or ventilation in patients with respiratory failure has become widespread, even more so since the coronavirus disease 2019 pandemic. The use of these modalities may impair the patient's ability to eat. "To breath or to eat" may become a dilemma. In this review, we identify the patients at risk of malnutrition that require medical nutritional therapy and understand the mechanisms of function of the devices to better give adapted nutritional indications for noninvasive ventilation or high flow nasal cannula.

RECENT FINDINGS

The Global Leadership Initiative for Malnutrition has been validated in the Intensive Care setting and can be used in patients requiring NIV. Many patients are underfed when receiving noninvasive ventilation therapies. HFNC may impair the swallowing ability and increase dysphagia while NIV may improve the swallowing reflexes. New technology preventing reflux and ensuring enteral feeding efficacy may increase the medical nutrition therapy safety and provide near-target energy and protein provision.

SUMMARY

The patient requiring noninvasive ventilation presents one of the most challenging nutritional challenges. The main steps to improve nutrition administration are to assess nutritional status, evaluate the presence of dysphagia, choose the most adequate tool of respiratory support, and adapt nutritional therapy (oral, enteral, or parenteral) accordingly.

Trends and clinical outcomes of abdominal compartment syndrome among intensive care hospitalizations

BACKGROUND

Abdominal compartment syndrome has been shown to be a highly morbid condition among patients admitted to the intensive care unit. The present study sought to characterize trends as well as clinical and financial outcomes of patients with abdominal compartment syndrome.

METHODS

The 2010 to 2020 National Inpatient Sample was used to identify adults (≥18 years) admitted to the intensive care unit. Standard mean differences were obtained to demonstrate effect size with >0.1 denoting significance. Hospitals were divided into tertiles based on annual institutional intensive care unit admissions. Multivariable regression models were used to evaluate the association of abdominal compartment syndrome on outcomes. The primary endpoint was in-hospital mortality, while complications, costs, and length of stay were secondarily considered.

RESULTS

Of 11,804,585 patients, 19,644 (0.17%) developed abdominal compartment syndrome. Over the study period, the incidence of abdominal compartment syndrome (2010-0.19%, 2020-0.20%, P < .001) remained similar. Those with abdominal compartment syndrome were more commonly admitted for gastrointestinal (22.8% vs 8.4%) and cardiovascular (22.6% vs 14.9%) etiologies and were more frequently managed at urban teaching hospitals (77.7% vs 65.1%) as well as high-volume intensive care units (85.2% vs 79.1%) (all standard mean differences >0.1). After adjustment, abdominal compartment syndrome was associated with higher odds of mortality (adjusted odds ratio: 3.84, 95% confidence interval: 3.57-4.13, reference: non-abdominal compartment syndrome). Incremental length of stay (β: +5.0 days, 95% confidence interval: 4.2-5.8) and costs (β: $49.3K, 95% confidence interval: 45.3-53.4) were significantly higher in abdominal compartment syndrome compared to non-abdominal compartment syndrome.

CONCLUSION

Abdominal compartment syndrome, while an uncommon occurrence among intensive care unit patients, remains highly morbid with significant resource burden. Further work exploring factors to mitigate its clinical and financial burden is needed.

The impact of musculoskeletal ill health on quality of life and function after critical care: a multicentre prospective cohort study

Physical disability is a common component of post-intensive care syndrome, but the importance of musculoskeletal health in this population is currently unknown. We aimed to determine the musculoskeletal health state of intensive care unit survivors and assess its relationship with health-related quality of life; employment; and psychological and physical function. We conducted a multicentre prospective cohort study of adults admitted to intensive care for > 48 h without musculoskeletal trauma or neurological insult. Patients were followed up 6 months after admission where musculoskeletal health state was measured using the validated Musculoskeletal Health Questionnaire score. Of the 254 participants, 150 (59%) had a musculoskeletal problem and only 60 (24%) had received physiotherapy after discharge. Functional Comorbidity Index, Clinical Frailty Scale, duration of intensive care unit stay and prone positioning were all independently associated with worse musculoskeletal health. Musculoskeletal health state moderately correlated with quality of life, rs = 0.499 (95%CI 0.392-0.589); anxiety, rs = -0.433 (95%CI -0.538 to -0.315); and depression, rs = -0.537 (95%CI -0.631 to -0.434) (all p < 0.001). Patients with a musculoskeletal problem were less physically active than those without a problem (median (IQR [range]) number of 30 min physical activity sessions per week 1 (0-3.25 [0-7]) vs. 4 (1-7 [0-7]), p < 0.001, respectively). This study found that musculoskeletal health problems were common after intensive care unit stay. However, we observed that < 25% of patients received physical rehabilitation after discharge home. Our work has identified potential high-risk groups to target in future interventional studies.

Construction of a Risk Prediction Model for the Occurrence of Acute Skin Failure in Critically Ill Patients: A Prospective Study

BACKGROUND

The risk factors for acute skin failure (ASF), a serious complication of the skin, are not fully understood.

PURPOSE

This study was designed to explore the risk factors for ASF in critically ill patients and construct a clinical prediction model.

METHODS

Intensive care unit patients were prospectively observed and assigned into two groups: with and without ASF. A logistic regression model was constructed, and its predictive power and clinical utility were evaluated.

RESULTS

Of the 204 eligible patients enrolled as participants, 58 (28.43%) developed ASF. Sepsis, vasoactive drugs, and age were shown to be risk factors for ASF, whereas peripheral perfusion index ratio and albumin level were shown to be protective factors. The area under the receiver operating characteristic curve was 0.83. The maximum Youden index of the model was 0.39 (specificity: 0.87, sensitivity: 0.77). The Hosmer-Lemeshow test (p = .20) and calibration curve showed good fitness and predictive utility with respect to the model.

CONCLUSIONS

The developed model effectively predicts ASF risk, allowing for the early identification of high-risk patients. Identifying risk factors such as sepsis, vasoactive drugs, and age and considering protective factors such as peripheral perfusion index and albumin levels may help optimize care plans. Clinical staff should pay special attention to these factors and their impact on skin health in critically ill patients.

Exploring the molecular mechanism of sepsis-associated encephalopathy by integrated analysis of multiple datasets

BACKGROUND

We aim to deal with the Hub-genes and signalling pathways connected with Sepsis-associated encephalopathy (SAE).

METHODS

The raw datasets were acquired from the Gene Expression Omnibus (GEO) database (GSE198861 and GSE167610). R software filtered the differentially expressed genes (DEGs) for hub genes exploited for Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Hub genes were identified from the intersection of DEGs via protein-protein interaction (PPI) network. And the single-cell dataset (GSE101901) was used to authenticate where the hub genes express in hippocampus cells. Cell-cell interaction analysis and Gene Set Variation Analysis (GSVA) analysis of the whole transcriptome validated the interactions between hippocampal cells.

RESULTS

A total of 161 DEGs were revealed in GSE198861 and GSE167610 datasets. Biological function analysis showed that the DEGs were primarily involved in the phagosome pathway and significantly enriched. The PPI network extracted 10 Hub genes. The M2 Macrophage cell decreased significantly during the acute period, and the hub gene may play a role in this biological process. The hippocampal variation pathway was associated with the MAPK signaling pathway.

CONCLUSION

Hub genes (Pecam1, Cdh5, Fcgr, C1qa, Vwf, Vegfa, C1qb, C1qc, Fcgr4 and Fcgr2b) may paticipate in the biological process of SAE.

Key lessons from the establishment of a nurse-led infection prevention and control program for COVID-19 in an Australian hotel quarantine and isolation service

BACKGROUND

A key aspect of Australia's response to the COVID-19 pandemic was to control transmission through legislated quarantine and isolation of overseas returning travellers and potentially infectious community members. In New South Wales, Special Health Accommodation (SHA) was rapidly established as a comprehensive health service for individuals that were at risk of having COVID-19, were confirmed to have COVID-19 or for those with complex health needs that were deemed inappropriate for management in Police managed Quarantine Hotels. SHA services were later expanded to care for community members who were COVID-19 positive and unable to effectively isolate, or contacts of individuals who were unable to quarantine effectively in their homes. SHA's unique nurse-led Infection Prevention and Control (IPC) program offers key lessons that may impact future programs.

METHODS

A reflection on the experience of leading an Infection Prevention and Control program in SHA was undertaken. This was supported by a review of SHA admission, workforce and transmission data and data obtained from a cross-sectional questionnaire aimed to better understand the experiences of a novel population of health workers (HW) in a comprehensive health-led quarantine and isolation service.

RESULTS

SHA program data demonstrates how its IPC program implementation prevented transmission of COVID-19 to SHA staff and patients. Responses from the questionnaire suggested staff felt safe and well-prepared through the IPC education they received. They also gained transferrable knowledge and skills, which they intend to use in future healthcare roles.

CONCLUSION

The SHA nurse-led IPC program offered successful quarantine and isolation for COVID-19 in non-purpose-built facilities. A review of IPC strategies and key lessons from the establishment of the SHA IPC program are of critical importance to planning and management of current and future pandemics.

"At Least I Can Push this Morphine": PICU Nurses' Approaches to Suffering Among Dying Children

CONTEXT

Parents of children who die in the pediatric intensive care unit (PICU) carry memories of their child's suffering throughout a lifelong grieving experience. Given their prolonged time at the bedside, PICU nurses are poised to attend to dying children's suffering.

OBJECTIVES

We aimed to explore how PICU nurses identify, assess, and attend to EOL suffering.

METHODS

Interpretive descriptive qualitative study with thematic analysis of virtual focus groups from a geographically diverse sample of PICU nurses.

RESULTS

Nurses participated in five focus groups (N = 19). Most identified as White (89%) females (95%) with a range of 1-24 years of PICU experience and involvement in >10 EOL care cases (89%). Nurses described approaches to suffering within five themes: 1) Identifying and easing perceptible elements; 2) Recognizing and responding to subtleties moment-to-moment; 3) Acclimating to family interdependence; 4) Synchronizing nurse in-the-room insight with systemic complexity; and 5) Accounting for ambiguity. Nurses detailed elements of suffering they could "fix" with straightforward, external interventions (e.g., pain medication). More complex tasks like optimizing care within familial and interprofessional team relationships while navigating psychosocial responses from children and families challenged nurses. Nurses attempted to minimize EOL suffering amidst ambiguity and complexity using internal processes including managing the environment and titrating moment-to-moment care.

CONCLUSIONS

While physical suffering may be remedied with direct nursing care, holistically attending to EOL suffering in the PICU requires both bolstering external processes and strengthening PICU nurses' internal resources. Improving psychosocial training and optimizing interprofessional care systems could better support dying children and their families.

Nurse-led intervention to improve oral mucosal health of intubated patients in the intensive care unit: A prospective study

BACKGROUND

This prospective study aimed to explore the effectiveness of an oral care intervention with Tegaderm on the oral mucosal health of intubated patients.

METHODS

A total of 70 intubated patients were included and randomly assigned to 1 of 3 groups, clean water brushing teeth (n = 23), brushing teeth combined with mouthwash (BTM) (n = 23), and brushing teeth combined with mouthwash and Tegaderm (BTMT) (n = 24). The Oral Mucositis Assessment Scale (OMAS) was applied to evaluate the patient's oral mucosal health before and after oral care intervention.

RESULTS

The BTMT group had lower OMAS scores in almost all regions of the oral cavity, compared to the brushing teeth and BTM groups. The general linear model for repeated measurement indicated the BTMT group had the lowest total OMAS scores from Day 2 to Day 4 after the initiation of baseline OMAS evaluation. Of the 3 intervention groups, the BTMT group had the shortest length of endotracheal intubation. The BTMT group had the lowest incidence rate of ventilator-associated pneumonia; however, no significant between-group differences were found.

CONCLUSIONS

BTMT effectively reduced the decline in oral mucosal health that was caused by endotracheal intubation and shortened the length of endotracheal intubation.

Provision and evaluation of explanations within an automated planning-based approach to solving the multimorbidity problem

The multimorbidity problem involves the identification and mitigation of adverse interactions that occur when multiple computer interpretable guidelines are applied concurrently to develop a treatment plan for a patient diagnosed with multiple diseases. Solving this problem requires decision support approaches which are difficult to comprehend for physicians. As such, the rationale for treatment plans generated by these approaches needs to be provided.

OBJECTIVE

To develop an explainability component for an automated planning-based approach to the multimorbidity problem, and to assess the fidelity and interpretability of generated explanations using a clinical case study.

METHODS

The explainability component leverages the task-network model for representing computer interpretable guidelines. It generates post-hoc explanations composed of three aspects that answer why specific clinical actions are in a treatment plan, why specific revisions were applied, and how factors like medication cost, patient's adherence, etc. influence the selection of specific actions. The explainability component is implemented as part of MitPlan, where we revised our planning-based approach to support explainability. We developed an evaluation instrument based on the system causability scale and other vetted surveys to evaluate the fidelity and interpretability of its explanations using a two dimensional comparison study design.

RESULTS

The explainability component was implemented for MitPlan and tested in the context of a clinical case study. The fidelity and interpretability of the generated explanations were assessed using a physician-focused evaluation study involving 21 participants from two different specialties and two levels of experience. Results show that explanations provided by the explainability component in MitPlan are of acceptable fidelity and interpretability, and that the clinical justification of the actions in a treatment plan is important to physicians.

CONCLUSION

We created an explainability component that enriches an automated planning-based approach to solving the multimorbidity problem with meaningful explanations for actions in a treatment plan. This component relies on the task-network model to represent computer interpretable guidelines and as such can be ported to other approaches that also use the task-network model representation. Our evaluation study demonstrated that explanations that support a physician's understanding of the clinical reasons for the actions in a treatment plan are useful and important.

Screening and early detection of post-extubation oropharyngeal dysphagia: a best practice implementation project

INTRODUCTION

Patients undergoing intubation and mechanical ventilation in an intensive care unit risk developing post-extubation oropharyngeal dysphagia (PED). PED can lead to aspiration complications, aspiration pneumonia, and prolonged hospitalization, as well as increased repeat intubation and in-hospital morbidity and mortality.

OBJECTIVE

This evidence implementation project aimed to promote evidence-based screening and early detection of PED in an adult intensive care unit in a secondary public hospital in Brazil.

METHOD

The project followed the seven-phase JBI Evidence Implementation Framework to promote changes at the study site. The JBI Practical Application of Clinical Evidence System (PACES) and Getting Research into Practice (GRiP) approach were also used. The project was developed considering the main barriers to best practices, which were identified through a baseline audit. An educational program was designed to address the identified barriers. Two follow-up audits were then conducted to assess the changes in compliance with the evidence-based practices.

RESULTS

The baseline audit showed deficits in current practices. The first follow-up audit indicated improved compliance with best practices, with five of the seven audit criteria showing 100% compliance. The second follow-up audit indicated that compliance remained at 100% for those five criteria and increased for the other two after an additional intervention to address poor results in nursing care documentation.

CONCLUSION

The first follow-up audit showed good adherence to the educational program for the screening and detection of PED by nurses. The second follow-up audit, in line with the new strategies, showed improvement in nursing documentation.

Impacts of three inspiratory muscle training programs on inspiratory muscles strength and endurance among intubated and mechanically ventilated patients with difficult weaning: a multicentre randomised controlled trial

BACKGROUND

Inspiratory muscle training (IMT) is well-established as a safe option for combating inspiratory muscles weakness in the intensive care setting. It could improve inspiratory muscle strength and decrease weaning duration but a lack of knowledge on the optimal training regimen raise to inconsistent results. We made the hypothesis that an innovative mixed intensity program for both endurance and strength improvement could be more effective. We conducted a multicentre randomised controlled parallel trial comparing the impacts of three IMT protocols (low, high, and mixed intensity) on inspiratory muscle strength and endurance among difficult-to-wean patients.

METHODS

Ninety-two patients were randomly assigned to three groups with different training programs, where each performed an IMT program twice daily, 7 days per week, from inclusion until successful extubation or 30 days. The primary outcome was maximal inspiratory pressure (MIP) increase. Secondary outcomes included peak pressure (Ppk) increase as an endurance marker, mechanical ventilation (MV) duration, ICU length of stay, weaning success defined by a 2-day ventilator-free after extubation, reintubation rate and safety.

RESULTS

MIP increases were 10.8 ± 11.9 cmH2O, 4.5 ± 14.8 cmH2O, and 6.7 ± 14.5 cmH2O for the mixed intensity (MI), low intensity (LI), and high intensity (HI) groups, respectively. There was a non-statistically difference between the MI and LI groups (mean adjusted difference: 6.59, 97.5% CI [- 14.36; 1.18], p = 0.056); there was no difference between the MI and HI groups (mean adjusted difference: - 3.52, 97.5% CI [- 11.57; 4.53], p = 0.321). No significant differences in Ppk increase were observed among the three groups. Weaning success rate observed in MI, HI and LI group were 83.7% [95% CI 69.3; 93.2], 82.6% [95% CI 61.2; 95.0] and 73.9% [95% CI 51.6; 89.8], respectively. MV duration, ICU length of stay and reintubation rate had similar values. Over 629 IMT sessions, six adverse events including four spontaneously reversible bradycardia in LI group were possibly related to the study.

CONCLUSIONS

Among difficult-to-wean patients receiving invasive MV, no statistically difference was observed in strength and endurance progression across three different IMT programs. IMT appears to be feasible in usual cares, but some serious adverse events such as bradycardia could motivate further research on the specific impact on cardiac system.

Ultrasonography for confirmation of gastric tube placement

BACKGROUND

Gastric tubes are commonly used for the administration of drugs and tube feeding for people who are unable to swallow. Feeding via a tube misplaced in the trachea can result in severe pneumonia. Therefore, the confirmation of tube placement in the stomach after tube insertion is important. Recent studies have reported that ultrasonography provides good diagnostic accuracy estimates in the confirmation of appropriate tube placement. Hence, ultrasound could provide a promising alternative to X-rays in the confirmation of tube placement, especially in settings where X-ray facilities are unavailable or difficult to access.

OBJECTIVES

To assess the diagnostic accuracy of ultrasound alone or in combination with other methods for gastric tube placement confirmation in children and adults.

SEARCH METHODS

This systematic review is an update of a previously published Cochrane review. For this update, we searched the Cochrane Library (2021, Issue 6), MEDLINE (to April 2023), Embase (to April 2023), five other databases (to July 2021), and reference lists of articles, and contacted study authors.

SELECTION CRITERIA

We included studies that evaluated the diagnostic accuracy of naso- and orogastric tube placement confirmed by ultrasound visualization using X-ray visualization as the reference standard. We included cross-sectional studies and case-control studies. We excluded case series or case reports. We excluded studies if X-ray visualization was not the reference standard or if the tube being placed was a gastrostomy or enteric tube.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the methodological quality and extracted data from each of the included studies. We contacted the authors of the included studies to obtain missing data. There were sparse data for specificity. Therefore, we performed a meta-analysis of only sensitivity using a univariate random-effects logistic regression model to combine data from studies that used the same method and echo window.

MAIN RESULTS

We identified 12 new studies in addition to 10 studies included in the earlier version of this review, totalling 1939 participants and 1944 tube insertions. Overall, we judged the risk of bias in the included studies as low or unclear. No study was at low risk of bias or low concern for applicability in every QUADAS-2 domain. There were limited data (152 participants) for misplacement detection (specificity) due to the low incidence of misplacement. The summary sensitivity of ultrasound on neck and abdomen echo windows were 0.96 (95% confidence interval (CI) 0.92 to 0.98; moderate-certainty evidence) for air injection and 0.98 (95% CI 0.83 to 1.00; moderate-certainty evidence) for saline injection. The summary sensitivity of ultrasound on abdomen echo window was 0.96 (95% CI 0.65 to 1.00; very low-certainty evidence) for air injection and 0.97 (95% CI 0.95 to 0.99; moderate-certainty evidence) for procedures without injection. The certainty of evidence for specificity across all methods was very low due to the very small sample size. For settings where X-ray was not readily available and participants underwent gastric tube insertion for drainage (8 studies, 552 participants), sensitivity estimates of ultrasound in combination with other confirmatory tests ranged from 0.86 to 0.98 and specificity estimates of 1.00 with wide CIs. For studies of ultrasound alone (9 studies, 782 participants), sensitivity estimates ranged from 0.77 to 0.98 and specificity estimates were 1.00 with wide CIs or not estimable due to no occurrence of misplacement.

AUTHORS' CONCLUSIONS

Of 22 studies that assessed the diagnostic accuracy of gastric tube placement, few studies had a low risk of bias. Based on limited evidence, ultrasound does not have sufficient accuracy as a single test to confirm gastric tube placement. However, in settings where X-ray is not readily available, ultrasound may be useful to detect misplaced gastric tubes. Larger studies are needed to determine the possibility of adverse events when ultrasound is used to confirm tube placement.
