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.

Pain management interventions of the non-communicating patient in intensive care: What works for whom and why? A rapid realist review

AIM

The utility and uptake of pain management interventions across intensive care settings is inconsistent. A rapid realist review was conducted to synthesise the evidence for the purpose of theory building and refinement.

DESIGN

A five-step iterative process was employed to develop project scope/ research questions, collate evidence, appraise literature, synthesise evidence and interpret information from data sources.

METHODS

Realist synthesis method was employed to systematically review literature for developing a programme theory.

DATA SOURCES

Initial searches were undertaken in three electronic databases: MEDLINE, CINHAL and OVID. The review was supplemented with key articles from bibliographic search of identified articles. The first 200 hits from Google Scholar were screened.

RESULTS

Three action-oriented themes emerged as integral to successful implementation of pain management interventions. These included health facility actions, unit/team leader actions and individual nurses' actions.

CONCLUSION

Pain assessment interventions are influenced by a constellation of factors which trigger mechanisms yielding effective implementation outcomes.

IMPLICATIONS

The results have implications on policy makers, health organisations, nursing teams and nurses concerned with optimising the successful implementation of pain management interventions.

IMPACT

The review enabled formation of a programme theory concerned with explaining how to effectively implement pain management interventions in intensive care.

REPORTING METHOD

This review was informed by RAMESES publication standards for realist synthesis.

PUBLIC CONTRIBUTION

No patient or public contribution. The study protocol was registered in Open Science Framework. 10.17605/OSF.IO/J7AEZ.

Navigating tensions when life-sustaining treatment is withdrawn: A thematic synthesis of nurses' and physicians' experiences

AIM

To synthesise nurses' and physicians' experiences with withdrawing life-sustaining treatment in an intensive care unit.

DESIGN

The chosen methodology is thematic synthesis. The Preferred Reporting Items for Systematic Review and Meta-Analyses and Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement.

METHODS AND DATA SOURCES

A systematic search is conducted in APA PsycINFO, CINAHL Plus, EMBASE, PubMed and Web of Science following the inclusion and exclusion criteria in April 2023. Two reviewers independently screened and extracted the qualitative data. Subsequently, data analysis was conducted using thematic analysis of qualitative research. This study was not registered with any review registry due to the irrelevance of the data to health-related outcomes.

RESULTS

From the 16 articles, 267 quotes were extracted and analysed. The findings of the study revealed five analytical themes: (1) tensions between interdependent collaboration and hierarchical roles; (2) tensions between dignified dying or therapeutic perspectives; (3) family members' reflections of patient's wishes; (4) tensions in family members' positions; and (5) double-sidedness of distress.

CONCLUSION

This study contributes to nursing knowledge by providing a more nuanced understanding of this complex phenomenon of withdrawing life-sustaining treatment. The findings of this study have revealed significant variations globally in the practices surrounding the withdrawal of life-sustaining treatment in intensive care units, emphasising the need for further research to inform clinical practices that cater to diverse contexts.

REPORTING METHOD

Enhancing Transparency are used in Reporting the Synthesis of Qualitative Research Statement (ENTREQ statement).

PATIENT OR PUBLIC CONTRIBUTION

Since this study reported a potential collision between the patient's dignified dying and the family member's perceptions and interests, the family member's wishes should be carefully distinguished from the patient's quality of end of life in practice.

Noninvasive pediatric blood pressure assessment: exploring the clinicians' perspective

BACKGROUND

Obtaining accurate and reliable blood pressure (BP) readings in pediatric patients is challenging, given difficulties in adhering to measurement guidelines, limited device validation and variable patient cooperation. This study aimed to investigate clinicians' perspectives surrounding noninvasive pediatric BP assessment to identify opportunities for improvement in BP technology and clinical practice.

METHOD

Based on an adapted version of the extended Technology Acceptance Model 2, semi-structured interviews were conducted with clinicians involved in noninvasive pediatric BP assessment in a major Australian children's hospital. Transcripts were analyzed thematically and guided by Technology Acceptance Model 2.

RESULTS

Clinician responses ( n  = 20) revealed that poor patient tolerance of BP measurement resulting from excessive cuff inflation is a major hindrance to reliable pediatric BP assessment. Clinicians described low trust in BP readings from automated devices, often relating to poor patient tolerance to cuff inflation, thereby diminishing the clinical utility of these readings in informing treatment decisions. Auscultatory measurement was regarded as more trustworthy and better tolerated, but less convenient to perform as compared with oscillometric measurement.

CONCLUSION

A dissonance exists between (1) low trust and clinical utility of the most common and easy-to-use BP measurement approach (automated devices), versus (2) higher trust and clinical utility, but efficiency and user-related impediments, for the auscultatory method. Based on our results, we have developed the Blood Pressure Acceptance Model, which can be used to explain and predict clinicians' acceptance of BP technology. Further work is needed to improve the tolerability and accuracy of automated BP devices in real-world pediatric settings.

Factors impacting nursing assistants to accept a delegation in the acute care settings: A mixed method study

AIMS

To investigate the experience of nursing assistants being delegated nursing tasks by registered nurses.

DESIGN

Mixed method explanatory sequential design.

METHODS

A total of 79 nursing assistants working in an acute hospital in Australia completed surveys that aimed to identify their experience of working with nurses and the activities they were delegated. The survey data were analysed using descriptive statistics. Interviews with 11 nursing assistants were conducted and analysed using Braun and Clarke's thematic analysis. Results were triangulated to provide a richer understanding of the phenomena.

RESULTS

Most nursing assistants felt supported completing delegated care activities. However, there was confusion around their scope of practice, some felt overworked and believed that they did not have the right to refuse a delegation. Factors impacting the nursing assistant's decision to accept a delegation included the attitude of the nurses, wanting to be part of the team and the culture of the ward. Nursing assistants who were studying to be nurses felt more supported than those who were not.

CONCLUSIONS

Delegation is a two-way relationship and both parties need to be cognisant of their roles and responsibilities to ensure safe and effective nursing care is provided. Incorrectly accepting or refusing delegated activities may impact patient safety.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Highlights the need for implementing strategies to support safe delegation practices between the registered and unregulated workforce to promote patient safety.

IMPACT

Describes the experiences of nursing assistants working in the acute care environment when accepting delegated care from nurses. Reports a range of factors that inhibit or facilitate effective delegation practices between nurses and nursing assistants. Provides evidence to support the need for stronger education and policy development regarding delegation practices between nurses and unregulated staff.

REPORTING METHOD

Complied with the APA Style JARS-MIXED reporting criteria for mixed method research.

Medical Device-Related Pressure Injury Care and Prevention Training Program (DevICeU): Effects on intensive care nurses' knowledge, prevention performance and point prevalence

OBJECTIVE

To determine the effect of the training given to intensive care unit (ICU) nurses to prevent medical device-related pressure injuries (MDRPIs) on nurses' knowledge levels, their prevention performance, and the point prevalence (PP) of MDRPIs.

RESEARCH METHODOLOGY/DESIGN

A pre-post test intervention study without a control group.

SETTING

The study was conducted between May and July 2023 with ICU nurses in three phases: pre-training phase (E0) (104 nurses, 116 patients), training implementation phase (E) and post-training phase (E1) (89 nurses, 120 patients).

MAIN OUTCOME MEASURES

The data were collected by using the Patient (E0, E1) and Nurse (E0) Characteristic Forms, MDRPI Follow-up and Prevalence Form (E0, E1), D.E.V.I.C.E Performance Observation Checklist (E0, E1), MDRPI Knowledge Assessment Questionnaire (E0, E1), Braden Pressure Ulcer Risk Assessment Scale (E0, E1), Pressure Injury Grading Form (E0, E1), and Feedback Form about the Training Process (E).

RESULTS

The mean MDRPI knowledge score of the nurses increased significantly from E0 to E1 (13.23 ± 1.43 vs. 20.02 ± 1.30, p = 0.001), with the highest improvement in the staging and prevention themes. Nurses' MDRPI prevention performance increased significantly from E0 to E1 (2.15 ± 1.01 vs. 11.17 ± 1.65, p = 0.001). There was a significant difference between the PP rate at E0 (61.2 %) and E1 (27.5 %) (p = 0.001).

CONCLUSION

The study indicated that the training on MDRPIs given to ICU nurses increased their knowledge and prevention performance and decreased the prevalence of MDRPIs. However, further studies with a larger sample size are needed to confirm these findings.

IMPLICATIONS FOR CLINICAL PRACTICE

Since MDRPIs have more complex staging and prevention practices than conventional PIs, they require the adoption of a training approach that includes visual materials and practical methods in addition to theoretical knowledge. Accurate definitions of medical device dimensions and fixation, skin assessment, and prevention practices will lead to the desired outcome of reducing MDRPIs in ICUs.

The Impact of a Pharmacist-Driven Multicomponent Sleep-Promoting Protocol on Delirium in Critically Ill Patients

Background: Sleep deprivation is reported in 80% of patients in the intensive care unit (ICU) and is associated with delirium. Guidelines recommend implementing a sleep-promoting protocol in critically ill patients which may increase the quantity and quality of sleep and may decrease delirium. Our objective was to implement a pharmacist-led interdisciplinary sleep-promoting protocol and analyze its impact on delirium in ICU patients receiving mechanical ventilation (MV). Methods: The study involved pre-implementation education, protocol development, and post-implementation analysis. ICU pharmacists completed prospective patient chart reviews to reduce exposure to deliriogenic medications and assess the need for a pharmacologic sleep aid. The primary outcome was the incidence of delirium and delirium-free days. Secondary outcomes included ICU length of stay (LOS), incidence of MV, and pharmacist medication interventions. Results: Post-protocol patients (n = 185) had a higher incidence of delirium compared to pre-protocol patients (n = 237) (51.3% vs 39.0%; P = .01). Post-protocol patients had a higher average APACHE III score (P = <.001). Delirium-free days were not significantly different between groups (P = .97). Difference in ICU LOS was not significant (P = .80). More patients received MV post-protocol implementation (55.7% vs 36.1%; P < .001). Pharmacists documented a total of 113 medication interventions. Conclusion and Relevance: A pharmacist-led, ICU sleep-promoting protocol was successfully implemented but did not reduce the incidence of delirium or the administration of insomnia agents. Post-protocol patients had higher disease severity and were more likely to receive MV. Incidence of delirium was consistent with the national reported prevalence of ICU delirium. ICU pharmacists on all shifts had an active role in optimizing sleep.

Nutrition determinants of acute skeletal muscle loss in critically ill patients: A prospective observational cohort study

BACKGROUND

Skeletal muscle loss is associated with adverse outcomes in critically ill patients and risk factors of acute skeletal muscle loss are not well described. This study aims to determine the factors associated with acute skeletal muscle loss in critically ill patients.

METHODS

This prospective observational cohort study was conducted with patients who were expected to stay in the intensive care unit (ICU) for at least a week. Rectus femoris cross-sectional area (RFCSA) measurements were performed within 48 h of ICU admission and on study day 7. The percentage change in RFCSA and variables associated with this change were evaluated by univariate and multivariate regression analysis.

RESULTS

Over a 12-month period, 518 patients were assessed for eligibility and 44 critically ill patients with a mean age of 59.3 ± 10.9 years were enrolled; 52.3% of them were female. There were significant reductions in RFCSA (16.8 ± 16.5%; P < 0.001). The mean amounts of protein and energy consumed compared with those prescribed were 67.0 ± 28.8% and 71.5 ± 38.3%, respectively. Multivariate regression analysis revealed that frailty was independently associated with acute skeletal muscle loss after adjusting for confounding factors in our cohort of patients.

CONCLUSION

Frailty status before ICU admission is associated with acute skeletal muscle loss and may be important for identifying critically ill patients at high risk of muscle wasting.

Nursing care complexity as a predictor of adverse events in patients transferred from ICU to hospital ward after general surgery

OBJECTIVES

Predicting the likelihood of adverse events following discharge from the intensive care unit (ICU) can contribute to improving the quality of surgical care. This study aimed to evaluate the impact of nursing care complexity as a predictor of adverse event development in general surgery patients transferred from the ICU to the hospital ward.

METHODS

A prospective observational study was conducted with 100 patients in the ICU and general surgical inpatient unit of a training and research hospital in Istanbul, Turkey. The Nursing Care Complexity tool was used by ICU and hospital ward nurses to measure nursing complexity.

RESULTS

A total of 65 adverse events developed in 51 patients during hospital ward hospitalization after discharge from the ICU. Nursing care complexity evaluations by the ICU nurses predicted overall and some specific adverse events, while hospital ward nurses' evaluations predicted ICU readmission and some follow-up abnormalities such as patients' blood pressure, pulse rate, and laboratory results.

CONCLUSION

The results of the current study validate that nursing care complexity can serve as a valuable tool for predicting the risk of adverse events and ICU readmission following discharge from the ICU.

IMPLICATIONS FOR CLINICAL PRACTICE

The use of the Nursing Care complexity tool by the ICU and even hospital ward nurses after ICU discharge may have a significant impact on patient outcomes and contribute to the recognition of nursing efforts.

Diagnostic accuracy of the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium and Cornell Assessment of Pediatric Delirium for detecting delirium in the pediatric intensive care unit: A systematic review and meta-analysis

OBJECTIVES

Delirium is a frequent complication of critical illness, affecting 34% of children admitted to pediatric intensive care units. The commonly used tools for detecting delirium in the pediatric intensive care unit include the Pediatric Confusion Assessment Method for the intensive care unit (ICU, pCAM-ICU), Preschool Confusion Assessment Method for the ICU (psCAM-ICU), Pediatric Anesthesia Emergence Delirium and the Cornell Assessment of Pediatric Delirium.

DATA SOURCES

We searched four electronic databases for relevant articles from inception to March 1, 2023.

STUDY SELECTION

All full-text observational studies examining the sensitivity and specificity of the four tools for screening delirium in the pediatric intensive care units were included.

DATA EXTRACTION

Two researchers independently identified articles, extracted data, and retrieved the diagnostic accuracy parameters of the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium, and Cornell Assessment of Pediatric Delirium relative to standard references. A bivariate diagnostic statistical analysis with a random-effects model was performed.

DATA SYNTHESIS

Four, five, three and seven studies on the pediatric CAM-ICU, pre-school CAM-ICU, Pediatric Anesthesia Emergence Delirium, and Cornell Assessment of Pediatric Delirium, respectively, were identified. Due to the limited number of Pediatric Anesthesia Emergence Delirium articles included, no pooled diagnostic accuracy was produced. The pooled sensitivity was 0.73, 0.84, and 0.95 for the pediatric CAM-ICU, pre-school CAM-ICU, and Cornell Assessment of Pediatric Delirium, respectively, whereas the pooled specificity was 0.98, 0.90, and 0.81, respectively. The Cornell Assessment of Pediatric Delirium had greater sensitivity compared to both the pediatric CAM-ICU and pre-school CAM-ICU (both p = 0.04) and lower specificity than the pediatric CAM-ICU did (p < 0.001). Age, sample size, and mechanical ventilation use were significant moderators of the specificity of the pediatric CAM-ICU (p < 0.001, <0.001, and = 0.001, respectively).

CONCLUSIONS

Our data indicate that the Cornell Assessment of Pediatric Delirium is a more dependable instrument than the pediatric CAM-ICU and pre-school CAM-ICU for detecting pediatric intensive care delirium occurrence. More studies on the Pediatric Anesthesia Emergence Delirium are warranted.

IMPLICATIONS FOR CLINICAL PRACTICE

Healthcare providers are suggested adopting the Cornell Assessment of Pediatric Delirium into daily routine for the early detection of delirium in pediatric intensive care units.

Experiences of nursing students providing end of life care for children and young people: A focus group study

BACKGROUND

End of life care for Children and Young People (CYP) is known to be an emotive area of practice. Previous studies involving qualified nurses have demonstrated that nurses feel they need more end-of-life care education, as well as a platform for sharing experiences and discussing them with others. Evidence relating to nursing students remains limited despite being widely acknowledged as a difficult aspect of nursing education.

AIMS

This study aims to help improve understanding of the lived experiences of children's nursing students who have cared for a patient at, during, or immediately following end-of-life. The study describes the emotions experienced by children's nursing students and explores the student nurses' perceptions of education and support needs around caring for CYP during end-of-life care.

METHODOLOGY

A qualitative inquiry methodology allowed for a pragmatic approach to design this focus group study. Nine undergraduate student children's nurses participated in two focus groups. Ethical approval was granted by the host university. Thematic data analysis using Braun and Clarke's (2019) thematic analysis was conducted.

FINDINGS

Six themes emerged from the data; Emotional practice (1), the heart of the care (2), a lasting impact (3), hierarchy of grief (4), experience, knowledge and understanding (5), and the value of support (6). End of life care for children and young people is recognised by students as a sad but important part of the job role, which can have a lasting impact and which students required improved education and support for.

IMPLICATIONS FOR PRACTICE

Improved education on end-of-life care is required. This should be introduced early, encompassing practical approaches to the varied nature of end-of-life care, normalising a range of emotions and delayed responses. Furthermore, improved support is required for both student nurses and qualified staff, who are supporting students caring for CYP at the end of life.

Investigating the correlation of delirium after cardiac surgery with memories and posttraumatic stress disorder consequences of intensive care unit: A prospective cohort study

OBJECTIVES

To explore the differences in post-intensive care unit memory and posttraumatic stress disorder symptoms between patients with and without delirium, and assess the correlations between the two.

DESIGN

Prospective cohort observation study.

SETTING

A cardiac intensive care unit of a tertiary hospital in China. We enrolled 318 consecutive patients after cardiac surgery between December 2017 and March 2019.

MAIN OUTCOME MEASURES

Delirium was assessed using the Confusion Assessment Method for the ICU from intensive care unit admission to discharge. Intensive care unit memory was assessed using the ICU-Memory Tool through face-to-face interviews one week after discharge. Posttraumatic stress disorder was measured telephonically using the Impact of Events Scale-revised questionnaire at three months post-discharge.

RESULTS

Eighty patients each in the delirium and non-delirium groups were enrolled for follow-up interviews. Patients with delirium had vaguer memories of pre-intensive care unit admission and of their stay, and recollected more memories of feelings (vs. without delirium). Posttraumatic stress disorder was diagnosed in 14 patients with and in seven without delirium, with non-significant differences between groups. Delirium did not influence post-intensive care unit factual, feeling, and delusional memories, nor posttraumatic stress disorder and hyperarousal, intrusion, and avoidance. The memories of feelings were positively correlated with the last three (r = 0.285, r = 0.390 and r = 0.373, respectively).

CONCLUSION

Patients with delirium had vague intensive care unit memories. Memories of feelings were positively correlated with symptoms of hyperarousal, intrusion, and avoidance. Delirium did not influence factual, feeling, or delusional memories nor posttraumatic stress disorder incidence and symptoms.

IMPLICATIONS FOR CLINICAL PRACTICE

Interventions are needed to reduce the impact of vague memory in patients with post-intensive care unit delirium. Memories of feelings should be focused on because of their correlation with hyperarousal, intrusion, and avoidance. Delirium prevention and early recognition measures are suggested.

Prehospital lactate-glucose interaction in acute life-threatening illnesses: metabolic response and short-term mortality

BACKGROUND AND IMPORTANCE

Lactate is an already recognized biomarker for short-term mortality. However, how glycemia and diabetes affect the predictive ability of lactate needs to be revealed.

OBJECTIVE

To determine how hypoglycemia, normoglycemia, and hyperglycemia modify the predictive ability of lactate for short-term mortality (3 days). The secondary objective was to evaluate the predictive ability of lactate in diabetic patients.

DESIGN, SETTINGS AND PARTICIPANTS

Prospective, observational study performed between 26 October 2018 and 31 December 2022. Multicenter, EMS-delivery, ambulance-based study, considering 38 basic life support units and 5 advanced life support units referring to four tertiary care hospitals (Spain). Eligible patients were adults recruited from among all phone requests for emergency assistance who were later evacuated to emergency departments.

OUTCOMES MEASURE AND ANALYSIS

The primary outcome was in-hospital mortality from any cause within the third day following EMS attendance. The main predictors considered were lactate, blood glucose levels and previous diabetes.

MAIN RESULTS

A total of 6341 participants fulfilled the inclusion criteria. 68 years (IQR: 51-80); 41.4% were female. The 3-day in-hospital mortality rate was 3.5%. The predictive capacity of lactate for 3-day mortality was only significantly different between normo-glycemia and hyperglycemia. The best predictive result was for normo-glycemia - AUC = 0.897 (95% CI: 0.881-0.913) - then hyperglycemia - AUC = 0.819 (95% CI: 0.770-0.868) and finally, hypoglycemia - AUC = 0.703 (95% CI: 0.422-0.983). The stratification according to diabetes presented no statistically significant difference, and the predictive results were AUC = 0.924 (95% CI: 0.892-0.956), AUC = 0.906 (95% CI: 0.884-0.928), and AUC = 0.872 (95% CI: 0.817-0.927) for nondiabetes, uncomplicated cases, and end-organ damage diabetes, respectively.

CONCLUSION

Our results demonstrated that glycemia, but not diabetes, alters the predictive ability of lactate. Therefore, hyperglycemia should be considered when interpreting lactate, since this could improve screening to detect cryptic shock conditions.

The psychological well-being index and quality of life after a cardiac rehabilitation program based on aerobic training and psychosocial support

BACKGROUND

This study aimed to investigate the physical and psychological benefits of an alternative cardiac rehabilitation program based on therapeutic groups during physical exercise sessions and to compare the results with those of a conventional cardiac rehabilitation program.

METHOD

The sample included 112 patients from the cardiac rehabilitation unit of a medical center, 91.1 % of whom were male. The control group consisted of 47 subjects, with a mean age of 57.89 ± 12.30 and the experimental group consisted of 65 subjects, with a mean age of M = 58.38 ± 9.86. Quality of life, psychological well-being, health-related quality of life, body mass index, blood pressure, abdominal circumference and resting heart rate were measured before starting and at the end of the cardiac rehabilitation program.

RESULTS

The experimental group improved significantly more than the control group in body mass index, systolic and diastolic blood pressure, abdominal circumference, and resting heart rate (p value < 0.005). In addition, the experimental group had significantly greater improvements in quality of life, psychological well-being, and health-related quality of life than the control group (p-value < 0.001).

CONCLUSIONS

A cardiac rehabilitation program based on simultaneous aerobic training and psychosocial support improved the physical function, health-related quality of life and well-being.

Job satisfaction and burnout syndrome among intensive-care unit nurses: A systematic review and meta-analysis

INTRODUCTION

The severe conditions often experienced in an intensive care unit, combined with poor working conditions, increase stress and therefore decrease job satisfaction. Sustained stress in the workplace leads to the development of burnout, a syndrome characterised by three dimensions: emotional exhaustion, depersonalisation and perceived lack of personal fulfilment.

OBJECTIVE

To analyse the relationship between burnout syndrome and job satisfaction among ICU personnel.

DATA SOURCES

The PubMed, CINAHL and Scopus databases were used.

STUDY DESIGN

A systematic review and meta-analysis. The study sample consisted of 18 quantitative primary studies conducted in the last five years. Validated questionnaires were used to assess burnout in ICU healthcare workers, the most commonly used being the Maslach Burnout Inventory.

EXTRACTION METHODS

The search equation applied was: "job satisfaction AND nurs* AND burnout AND (ICU OR intensive care units)". The search was performed in October 2022.

PRINCIPAL FINDINGS

The search returned 514 results. Only 73 articles met the eligibility criteria. After reading the title and abstract, 20 articles were selected. After reading the full texts, 12 articles remained and after the reverse search, 18 articles were finally selected. The studies reported a 50% prevalence of burnout, all three dimensions of which were heightened by the COVID-19 pandemic. Analysis of the study findings revealed an inverse association between burnout and job satisfaction.

CONCLUSIONS

Job dissatisfaction of ICU nurses depends on lack of experience, working conditions or working environment among others. ICU nurses with lower job satisfaction have higher levels of burnout.

IMPLICATIONS FOR CLINICAL PRACTICE

This meta-analysis shows the potential value of job satisfaction on improving health outcomes related to burnout syndrome for nursing professional in Intensive Care Units. Different factors that could increase job satisfaction and consequently protect them from suffering high levels of burnout, such as salary, permanence in the service, mental health care are the responsibility of the hospital supervisor and, finally, of the own Health System. Knowledge of a risk profile based on the factors influencing job dissatisfaction would enable the implementation of effective workplace interventions to reduce or prevent the risk of burnout. Health policies should focus on protecting the worker, so in addition to improving working conditions, it would be interesting to promote coping skills in order to improve the quality of care and patient safety.

The role of caffeine in headache disorders

PURPOSE OF REVIEW

Caffeine is known to have both beneficial and adverse effects in individuals with headache disorders. This review describes recent findings regarding caffeine that are relevant to headache disorders and puts these findings into the context of clinical management.

RECENT FINDINGS

Preclinical studies show that caffeine has complex effects on sleep, brain blood flow, and intracranial pressure that may depend on the timing of caffeine intake relative to the sleep-wake cycle. Caffeine metabolism may have significant inter-individual variation that influences its therapeutic and/or adverse effects. Caffeine has acute therapeutic benefit for some primary headache disorders. For migraine, this benefit is predominantly in milder headache without cutaneous allodynia. High levels of caffeine intake may contribute to progression of headache disorders. Caffeine-containing combination analgesics commonly cause medication overuse headache. Abrupt reduction in caffeine consumption is a trigger for migraine that may be important in situations including the hospital setting, religious and cultural fasting, and pregnancy.

SUMMARY

There is not sufficient evidence to support universal guidelines for the use of dietary and medicinal caffeine in headache disorders. A sensible approach based upon available evidence is to limit dietary caffeine intake to moderate amounts with consistent timing before noon, and to use caffeine-containing combination analgesics infrequently for milder headache.

Opening Pandora's box by generating ICU diaries through artificial intelligence: A hypothetical study protocol

BACKGROUND

Patients and families on Intensive Care Units (ICU) benefit from ICU diaries, enhancing their coping and understanding of their experiences. Staff shortages and a limited amount of time severely restrict the application of ICU diaries. To counteract this limitation, generating diary entries from medical and nursing records using an artificial intelligence (AI) might be a solution.

DESIGN AND PURPOSE

Protocol for a hypothetical multi-center, mixed method study to identify the usability and impact of AI-generated ICU diaries, compared with hand-written diaries.

METHOD

A hand-written ICU diary will be written for patients with expected length of stay ≥ 72 h by trained nursing staff and families. Additionally at discharge, the medical and nursing records are analyzed by an AI software, transformed into understandable, empathic diary entries, and printed as diary. Based on an appointment with patients within 3 months, diaries are read in randomized order by trained clinicians with the patients and families. Patients and families will be interviewed about their experiences of reading both diaries. In addition, usability of diaries will be evaluated by a questionnaire.

EXPECTED FINDINGS AND RESULTS

Patients and families describe the similarities and differences of language and the content of the different diaries. In addition, concerns can be expressed about the generation and data processing by AI.

IMPLICATIONS FOR PRACTICE

Professional nursing involves empathic communication, patient-centered care, and evidence-based interventions. Diaries, beneficial for ICU patients and families, could potentially be generated by Artificial Intelligence, raising ethical and professional considerations about AI's role in complementing or substituting nurses in diary writing.

CONCLUSIONS

Generating AI-based entries for ICU diaries is feasible, but raises serious questions about nursing ethics, empathy, data protection, and values of professional nurses. Researchers and developers shall discuss these questions in detail, before starting such projects and opening Pandora's box, that can never be closed afterwards.

Clinical application of intrapulmonary percussive ventilation: A scoping review

Impaired respiratory function secondary to acute or chronic respiratory disease poses a significant clinical and healthcare burden. Intrapulmonary percussive ventilation (IPV) is used in various clinical settings to treat excessive airway secretions, pulmonary atelectasis, and impaired gas exchange. Despite IPV's wide use, there is a lack of clinical guidance on IPV application which may lead to inconsistency in clinical practice. This scoping review aimed to summarise the clinical application methods and dosage of IPV used by clinicians and researchers to provide guidance. A two-staged systematic search was conducted to retrieve studies that used IPV in inpatient and outpatient settings. MEDLINE, EMBASE, CINAHL, Scopus, and Google scholar were searched from January 1979 till 2022. Studies with patients aged ≥16 years and published in any language were included. Two reviewers independently screened the title and abstract, reviewed full text articles, and extracted data. Search yielded 514 studies. After removing duplicates and irrelevant studies, 25 studies with 905 participants met the inclusion criteria. This is the first scoping review to summarise IPV application methods and dosages from the available studies in intensive care unit (ICU), acute inpatient (non-ICU), and outpatient settings. Some variations in clinical applications and prescribed dosages of IPV were noted. Despite variations, common trends in clinical application and prescription of IPV dosages were observed and summarised to assist clinicians with IPV intervention. Although an evidence-based clinical guideline could not be provided, this review provides detailed information on IPV application and dosages in order to provide clinical guidance and lays a foundation towards developing a clinical practice guideline in the future.

Resistance training combined with β-hydroxy β-methylbutyrate for patients with critical illness: A four-arm, mixed-methods, feasibility randomised controlled trial

OBJECTIVES

This study aimed to assess the feasibility, safety, acceptability, and potential effectiveness of resistance training (RT) with or without β-Hydroxy β-Methylbutyrate (HMB) intervention program for ICU patients.

DESIGN

Open-label, parallel group, mixed method, randomized controlled trial.

SETTINGS

A tertiary general hospital in Fuzhou, China.

METHODS

Participants were randomly allocated to one of four groups. The RT group received supervised multilevel resistance training (RT) using elastic bands, administered by trained ICU nurses. The HMB group received an additional daily dose of 3.0 g HMB. The combination group underwent both interventions concurrently, while the control group received standard care. These interventions were implemented throughout the entire hospitalization period. Primary outcomes included feasibility indicators such as recruitment rate, enrollment rate, retention rate, and compliance rate. Secondary outcomes covered adverse events, acceptability (evaluated through questionnaires and qualitative interviews), and physical function. Quantitative analysis utilized a generalized estimation equation model, while qualitative analysis employed directed content analysis.

RESULTS

All feasibility indicators met predetermined criteria. Forty-eight patients were randomly assigned across four arms, achieving a 96% enrollment rate. Most patients adhered to the intervention until discharge, resulting in a 97.9% retention rate. Compliance rates for both RT and HMB interventions approached or exceeded 85%. No adverse events were reported. The intervention achieved 100% acceptability, with a prevailing expression of positive experiences and perception of appropriateness. The RT intervention shows potential improvement in physical function, while HMB does not.

CONCLUSIONS

Implementing nurse-led resistance training with elastic bands with or without HMB proved to be feasible and safe for ICU patients.

IMPLICATIONS FOR CLINICAL PRACTICE

A large-scale, multicenter clinical trials are imperative to definitively assess the impact of this intervention on functional outcomes in this population.

A longitudinal study to determine if all critically ill patients should be considered at nutrition risk or is there a highly accurate screening tool to be adopted?

BACKGROUND

Nutrition risk is prevalent in intensive care unit (ICU) settings and related to poor prognoses. We aimed to evaluate the concurrent and predictive validity of different nutrition risk screening tools in the ICU.

METHODS

Data were collected between 2019 and 2022 in six ICUs (n = 450). Nutrition risk was evaluated by modified Nutrition Risk in Critically ill (mNUTRIC), Nutritional Risk Screening (NRS-2002), Malnutrition Screening Tool (MST), Malnutrition Universal Screening Tool (MUST), and Nutritional Risk in Emergency (NRE-2017). Accuracy and agreement of the tools were assessed; logistic regression was used to verify the association between nutrition risk and prolonged ICU stay; Cox regression was used for mortality in the ICU, both with adjustment for confounders.

RESULTS

NRS-2002 ≥5 showed the best accuracy (0.63 [95% CI, 0.58-0.69]) with mNUTRIC, and MST with NRS-2002 ≥5 (0.76 [95% CI, 0.71-0.80]). All tools had a poor/fair agreement with mNUTRIC (k = 0.019-0.268) and moderate agreement with NRS-2002 ≥5 (k = 0.474-0.503). MUST (2.26 [95% CI 1.40-3.63]) and MST (1.69 [95% CI, 1.09-2.60]) predicted death in the ICU, and the NRS-2002 ≥5 (1.56 [95% CI 1.02-2.40]) and mNUTRIC (1.86 [95% CI, 1.26-2.76]) predicted prolonged ICU stay.

CONCLUSION

No nutrition risk screening tool demonstrated a satisfactory concurrent validity; only the MUST and MST predicted ICU mortality and the NRS-2002 ≥5 and mNUTRIC predicted prolonged ICU stay, suggesting that it could be appropriate to adopt the ESPEN recommendation to assess nutrition status in patients with ≥48 h in the ICU.

Pressure injuries in mechanically ventilated COVID-19 patients utilising different prone positioning techniques - A prospective observational study

OBJECTIVES

To compare the incidence and distribution of pressure injuries (PIs) with two approaches to prone positioning for mechanically ventilated COVID-19 patients, and to determine the prevalence of these PIs on intensive care unit (ICU) and hospital discharge.

DESIGN

A prospective observational study.

SETTING

Adult patients admitted to a quaternary ICU with COVID-19-associated acute lung injury, between September 2021 and February 2022.

MAIN OUTCOME MEASURES

Incidence and anatomical distribution of PIs during ICU stay for "Face Down" and "Swimmers Position" as well as on ICU and hospital discharge.

RESULTS

We investigated 206 prone episodes in 63 patients. In the Face Down group, 26 of 34 patients (76 %) developed at least one PI, compared to 10 of 22 patients (45 %) in the Swimmers Position group (p = 0.02). Compared to the Swimmers Position group, the Face Down group developed more pressure injuries per patient (median 1 [1, 3] vs 0 [0, 2], p = 0.04) and had more facial PIs (p = 0.002). In a multivariate logistic regression model, patients were more likely to have at least one PI with Face Down position (OR 4.67, 95 % CI 1.28, 17.04, p = 0.02) and greater number of prone episodes (OR 1.75, 95 % CI 1.12, 2.74, p = 0.01). Over 80 % of all PIs were either stage 1 or stage 2. By ICU discharge, 29 % had healed and by hospital discharge, 73 % of all PIs had healed.

CONCLUSION

Swimmers Position had a significantly lower incidence of PIs compared to the Face Down approach. One-quarter of PIs had healed by time of ICU discharge and three-quarters by time of hospital discharge.

IMPLICATIONS FOR CLINICAL PRACTICE

There are differences in incidence of PIs related to prone positioning approaches. This study validates and helps better inform current prone position guidelines recommending the use of Swimmers Position. The low prevalence of PIs at hospital discharge is reassuring.

Photographs in burn patient diaries: A qualitative study of patients' and nurses' experiences

OBJECTIVE

To explore burn patients' and burn intensive care nurses' experiences of the photos in patient diaries.

DESIGN

A qualitative inductive study using thematic analysis was performed. We conducted individual interviews with six former burn patients (age range 20-77 years; four women), and two focus groups with 11 burn intensive care nurses (age range 38-61 years; all women). Data from patients and nurses were analysed together, and the findings reported according to the consolidated criteria for reporting qualitative research (COREQ).

SETTING

A Norwegian burn centre where the writing of diaries including text and photos has been practiced for approximately two decades.

FINDINGS

Three main themes were derived from the combined analysis of the two data sets: hesitating when facing photos; visualising others care; and visualising the trajectory from burn trauma to recovery. Although the patients worried beforehand about what they would see in the photos and the nurses feared to select frightening photos, the photos were welcome, and several patients said they would have liked even more. The photos filled in gaps of memory, told more than words, and did not lie. Photos of family, friends or staff demonstrated shared actions that supported memories and recovery.

CONCLUSION

Both the burn patients and the burn intensive care nurses considered photos to be an essential part of the diary that gave context and provided a factual presentation of the patients' pathway of treatment, care and recovery.

IMPLICATION FOR CLINICAL PRACTICE

Tailored information about photo content should be offered to patients before a diary is handed over to them. Nurses should attempt to include photos covering the patients' entire stay at the burn centre, as well as photos of family, friends and staff. Individual nurses should be supported in their practical selection of photos for the diary.

An Evolutionary Concept Analysis of the "Fighter" in the Intensive Care Unit

The purpose of this article was to analyze the concept of "the fighter in the intensive care unit (ICU)" per the scientific literature and the impact this mentality has on care administered in the ICU. A literature review and a concept analysis based on Rodger's evolutionary method were performed to identify surrogate terms, antecedents, attributes, and consequences pertaining to the "fighter" in the ICU. Thirteen articles with a focus on "the fighter" were included in this analysis. There is a strong desire to remain optimistic and maintain high spirits as a coping mechanism in the face of extreme prognostic uncertainty. Themes that emerged from the literature were the need to find inner strength and persist in the face of adversity. The concept of "the fighter in the ICU" can serve as either adaptive or maladaptive coping, depending on the larger clinical picture. Patient experiences in the ICU are fraught with physical and psychological distress. How the patient and family unit cope during this anxiety-provoking time is based on the individual. Maintaining optimism and identifying as a fighter can be healthy ways to adapt to the circumstances. This concept analysis highlights the importance of holistic care and instilling hope particularly as patients may be nearing the end of life.

Exploring patients' and families' preferences for auditory stimulation in ICU delirium prevention: A qualitative study

OBJECTIVES

To explore the preferences of patients and families for delirium prevention by auditory stimulation in intensive care units.

RESEARCH METHODOLOGY

One-on-one, face-to-face, semistructured interviews with 17 participants (6 patients and 11 family members) were conducted at a step-down unit in a tertiary general hospital using a descriptive qualitative design. The data were analyzed via inductive thematic analysis.

RESULTS

Four major themes and ten subthemes emerged from the interviews: (1) reality orientation; (2) emotional support; (3) links to the outside; and (4) promising future.

CONCLUSIONS

The results in this qualitative study shed light on patients' and families' preferences for auditory stimulation in preventing ICU delirium. The participation of family members plays a crucial role in preventing ICU delirium. Family members can assist patients in reducing confusion about the situation by providing accurate and clear reality orientation. The emotional support and promising future provided by family members can help patients regain confidence and courage, which are often lacking in ICU patients. Linking patients to the outside world helps them stay connected, understand what is happening outside and reduce feelings of isolation.

IMPLICATIONS FOR CLINICAL PRACTICE

These findings can help health care staff gain insight into patients' and families' preferences and needs for auditory stimulation. Furthermore, these findings pave the way for crafting effective auditory interventions.

Responding to the real problem of sustainable resuscitation skills with real assessment. Mixed-methods evaluation of an authentic assessment programme

INTRODUCTION

The retention of resuscitation skills is a widespread concern, with a rapid decay in competence frequently following training. Meanwhile, training programmes continue to be disconnected with real-world expectations and assessment designs remain in conflict with the evidence for sustainable learning. This study aimed to evaluate a programmatic assessment pedagogy which employed entrustment decision and the principles of authentic and sustainable assessment (SA).

METHODS

We conducted a prospective sequential explanatory mixed methods study to understand and address the sustainable learning challenges faced by final-year undergraduate paramedic students. We introduced a programme of five authentic assessments based on actual resuscitation cases, each integrating contextual elements that featured in these real-life events. The student-tutor consensus assessment (STCA) tool was configured to accommodate an entrustment scale framework. Each test produced dual student led and assessor scores. Students and assessors were surveyed about their experiences with the assessment methodologies and asked to evaluate the programme using the Ottawa Good Assessment Criteria.

RESULTS

Eighty-four students participated in five assessments, generating dual assessor-only and student-led results. There was a reported mean score increase of 9% across the five tests and an 18% reduction in borderline or below scores. No statistical significance was observed among the scores from eight assessors across 420 unique tests. The mean student consensus remained above 91% in all 420 tests. Both student and assessor participant groups expressed broad agreement that the Ottawa criteria were well-represented in the design, and they shared their preference for the authentic methodology over traditional approaches.

CONCLUSION

In addition to confirming local sustainability issues, this study has highlighted the validity concerns that exist with conventional resuscitation training designs. We have successfully demonstrated an alternative pedagogy which responds to these concerns, and which embodies the principles of SA, quality in assessment practice, and the real-world expectations of professionals.

Sleep Disturbance During Post-Traumatic Amnesia and Early Recovery After Traumatic Brain Injury

After moderate to severe traumatic brain injury (TBI), sleep disturbance commonly emerges during the confused post-traumatic amnesia (PTA) recovery stage. However, the evaluation of early sleep disturbance during PTA, its recovery trajectory, and influencing factors is limited. This study aimed to evaluate sleep outcomes in patients experiencing PTA using ambulatory gold-standard polysomnography (PSG) overnight and salivary endogenous melatonin (a hormone that influences the sleep-wake cycle) assessment at two time-points. The relationships between PSG-derived sleep-wake parameters and PTA symptoms (i.e., agitation and cognitive disturbance) were also evaluated. In a patient subset, PSG was repeated after PTA had resolved to assess the trajectory of sleep disturbance. Participants with PTA were recruited from Epworth HealthCare's inpatient TBI Rehabilitation Unit. Trained nurses administered overnight PSG at the patient bedside using the Compumedics Somté portable PSG device (Compumedics, Ltd., Australia). Two weeks after PTA had resolved, PSG was repeated. On a separate evening, two saliva specimens were collected (at 24:00 and 06:00) for melatonin testing. Results of routine daily hospital measures (i.e., Agitated Behavior Scale and Westmead PTA Scale) were also collected. Twenty-nine patients were monitored with PSG (mean: 41.6 days post-TBI; standard deviation [SD]: 28.3). Patients' mean sleep duration was reduced (5.6 h, SD: 1.2), and was fragmented with frequent awakenings (mean: 27.7, SD: 15.0). Deep, slow-wave restorative sleep was reduced, or completely absent (37.9% of patients). The use of PSG did not appear to exacerbate patient agitation or cognitive disturbance. Mean melatonin levels at both time-points were commonly outside of normal reference ranges. After PTA resolved, patients (n = 11) displayed significantly longer mean sleep time (5.3 h [PTA]; 6.5 h [out of PTA], difference between means: 1.2, p = 0.005). However, disturbances to other sleep-wake parameters (e.g., increased awakenings, wake time, and sleep latency) persisted after PTA resolved. This is the first study to evaluate sleep disturbance in a cohort of patients as they progressed through the early TBI recovery phases. There is a clear need for tailored assessment of sleep disturbance during PTA, which currently does not form part of routine hospital assessment, to suggest new treatment paradigms, enhance patient recovery, and reduce its long-term impacts.

Critical care nurses' role in rapid response teams: A qualitative systematic review

AIM

To analyse the qualitative evidence on the role of critical care nurses in rapid response teams.

DESIGN

Qualitative systematic review.

METHODS

This qualitative systematic review employed Bettany-Saltikov and McSherry's guidelines and is reported according to the Enhancing Transparency in Reporting the Synthesis of Qualitative Research checklist. Two pairs of blinded researchers screened the articles. The data were synthesised using a thematic analysis approach.

DATA SOURCES

A systematic literature search was conducted using the CINAHL, Embase and MEDLINE databases.

RESULTS

Seven studies were included, and three main roles were identified: (1) balancing between confidence and fear in clinical encounters, (2) facilitating collaboration and (3) managing challenging power dynamics in decision-making.

CONCLUSION

Critical care nurses possess extensive knowledge and skills in providing critical care to patients experiencing deterioration on general wards. They play a vital role in facilitating collaboration between team members and ward staff. Furthermore, within the rapid response team, critical care nurses assume leadership responsibilities by overseeing the comprehensive coordination of patient care and actively engaging in the decision-making process concerning patient care.

IMPLICATIONS FOR THE PROFESSION

Highlighting the central role of critical care nurses in rapid response teams as well such a team's benefits in healthcare organisations can promote applications for funding to support further quality assurance of rapid response teams and thus enhance patient safety.

IMPACT

Health care organisations can assure the quality of rapid response team by providing economical resources and training. The education providers should facilitate and standardise curriculum for critical care nursing students to achieve necessary knowledge and skills as members in rapid response teams.

Recent advances in cardiorespiratory monitoring in acute respiratory distress syndrome patients

BACKGROUND

Recent advances on cardiorespiratory monitoring applied in ARDS patients undergoing invasive mechanical ventilation and noninvasive ventilatory support are available in the literature and may have potential prognostic implication in ARDS treatment.

MAIN BODY

The measurement of oxygen saturation by pulse oximetry is a valid, low-cost, noninvasive alternative for assessing arterial oxygenation. Caution must be taken in patients with darker skin pigmentation, who may experience a greater incidence of occult hypoxemia. Dead space surrogates, which are easy to calculate, have important prognostic implications. The mechanical power, which can be automatically computed by intensive care ventilators, is an important parameter correlated with ventilator-induced lung injury and outcome. In patients undergoing noninvasive ventilatory support, the use of esophageal pressure can measure inspiratory effort, avoiding possible delays in endotracheal intubation. Fluid responsiveness can also be evaluated using dynamic indices in patients ventilated at low tidal volumes (< 8 mL/kg). In patients ventilated at high levels of positive end expiratory pressure (PEEP), the PEEP test represents a valid alternative to passive leg raising. There is growing evidence on alternative parameters for evaluating fluid responsiveness, such as central venous oxygen saturation variations, inferior vena cava diameter variations and capillary refill time.

CONCLUSION

Careful cardiorespiratory monitoring in patients affected by ARDS is crucial to improve prognosis and to tailor treatment via mechanical ventilatory support.

Prognostic implications of delirium after Left Ventricular Assist Device (LVAD) implantation: A retrospective study

INTRODUCTION

In critically ill patients, delirium is a prognostic indicator of morbidity and mortality. This study investigates the impact of a delirium diagnosis on outcomes after Left Ventricular Assist Device (LVAD) implantation.

METHODS

This retrospective study included all adult patients who received LVADs at our institution between January 2016 and December 2020. We compared pre-implantation characteristics between the two groups, with and without a diagnosis of delirium, and compared their outcomes, including 1-month, 6-month, and in-hospital mortality, as well as re-intubation rate, length of stay (LOS), discharge disposition, and readmission rates.

RESULTS

In total, 361 patients (26.7% women, 75.8% African American) received durable LVADs. Ninety-four patients (26.1%) were diagnosed with delirium during the index admission. Pre-implantation demographic characteristics, past medical and psychiatric conditions, Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Profile, and laboratory values did not differ between the two groups with and without a diagnosis of delirium; older age (59 vs 56; P=0.03) was associated with delirium. Delirium diagnosis was associated with higher 1-month (P=0.007), 6-month (P=0.004), and in-hospital mortality (P<0.001), unplanned re-intubations (P<0.001), and a lower likelihood of discharge home (P = 0.03). Total hospital and ICU LOS were higher in patients with a diagnosis of delirium, though these results were not statistically significant. Readmission to hospital after index admission was quicker in patients with a diagnosis of delirium, but this result was not statistically significant.

CONCLUSIONS

In this study, a diagnosis of delirium during the LVAD implantation admission was associated with higher mortality, adverse post-surgical outcomes, and unfavorable discharge dispositions. Future prospective research is needed to validate the prognostic implications of delirium in both the short and long term. Additionally, there is a need to identify modifiable risk factors associated with delirium to promote early diagnosis and implement evidence-based management strategies to enhance outcomes within this population.

"It's a Heavy Thing to Carry:" Internal Medicine and Pediatric Resident Experiences Caring for Dying Patients

BACKGROUND

Residents often feel unprepared to care for dying patients and may benefit from more training. Little is known about factors in the clinical setting that promote resident learning about end of life (EOL) care.

OBJECTIVES

This qualitative study aimed to characterize the experiences of residents caring for dying patients and elucidate the impact of emotional, cultural, and logistical factors on learning.

METHODS

6 US internal medicine and 8 pediatric residents who had cared for at least 1 dying patient completed a semi-structured one-on-one interview between 2019 and 2020. Residents described an experience caring for a dying patient including their confidence in clinical skills, emotional experience, role within the interdisciplinary team, and perspective on how to improve their education. Interviews were transcribed verbatim and investigators conducted content analysis to generate themes.

RESULTS

3 themes (with subthemes) emerged: (1) experiencing strong emotion or tension (loss of patient personhood, emerging professional identity, emotional dissonance); (2) processing the experience (innate resilience, team support); and (3) recognition of a new perspective or skill (bearing witness, meaning making, recognizing biases, emotional work of doctoring).

CONCLUSIONS

Our data suggests a model for the process by which residents learn affective skills critical to EOL care: residents (1) notice strong emotion, (2) reflect on the meaning of the emotion, and (3) crystallize this reflection into a new perspective or skill. Educators can use this model to develop educational methods that emphasize normalization of physician emotions and space for processing and professional identity formation.

How often are infusion sets for central venous catheters changed in Australian and New Zealand Intensive Care Units? A point prevalence survey

BACKGROUND

Infusion sets (comprising the tubing, measuring burettes, fluid containers, transducers) that are connected to invasive vascular devices are changed on a regular basis in an effort to reduce bacterial colonisation and bloodstream infection. There is a balance between reducing infection and creating unnecessary waste. Current evidence suggests that for central venous catheters (CVCs), changing infusion sets at 7 days does not increase infection risks.

OBJECTIVES

The objective of this study was to describe the current unit guidelines in Australian and New Zealand intensive care units (ICUs) for changing infusion sets for CVCs.

METHODS

prospective cross-sectional point prevalence study, as a part of the 2021 Australian and New Zealand Intensive Care Society Point Prevalence Program.

PARTICIPANTS

Australia and New Zealand (ANZ) adult ICUs and their patients on the day of the study.

RESULTS

Data were collected from 51 ICUs across ANZ. One-third of these (16/49) ICUs had a guideline that specified a 7-day replacement period, with the rest having a more frequent replacement period.

CONCLUSION

Most ICUs participating in this survey had policies to change their CVC infusion tubing in 3-4 days, and recent high-level evidence supports an update to extend this to 7 days. There remains work to be done to spread this evidence to ANZ ICUs and improve environmental sustainability initiatives.

Early mobility and family partnerships in the intensive care unit: A scoping review of reviews

BACKGROUND

Critical illness significantly impacts the well-being of patients and families. Previous studies show that family members are willing to participate in patient care. Involving families in early mobility interventions may contribute to improved recovery and positive outcomes for patients and families.

AIM

In this scoping review, we investigated early mobility interventions for critically ill patients evaluated in randomized controlled trials and the extent to which family engagement in those interventions are reported in the literature.

STUDY DESIGN

In this scoping review of reviews, EMBASE, CINAHL, PubMed and Cochrane Central databases were searched in October 2019 and updated in February 2022. Systematic reviews were included and assessed using A MeaSurement Tool to Assess Systematic Reviews (AMSTAR) 2. Data were synthesized using a narrative approach. PRISMA-ScR guidelines were adhered to for reporting.

RESULTS

Thirty-three reviews were included which described a range of early mobility interventions for critically ill patients; none explicitly mentioned family engagement. Almost half of the reviews were of low or critically low quality. Insufficient detail of early mobility interventions prompted information to be extracted from the primary studies.

CONCLUSIONS

There are a range of early mobility interventions for critically ill patients but few involve families. Given the positive outcomes of family participation, and family willingness to participate in care, there is a need to explore the feasibility and acceptability of family participation in early mobility interventions.

RELEVANCE TO CLINICAL PRACTICE

Family engagement in early mobility interventions for critically ill patients should be encouraged and supported. How to best support family members and clinicians in enacting family involvement in early mobility requires further investigation.

Translation and Psychometric Validation of the German Version of the Iceland-Family Perceived Support Questionnaire (ICE-FPSQ): A Cross-Sectional Study

Supporting families experiencing critical illness through family interventions is essential to ease illness burden, enable family management, and reduce their risk for adverse health. Thus far, there is no validated German instrument to measure the perceived support families receive from nurses. We translated the 14-item Iceland-Family Perceived Support Questionnaire (ICE-FPSQ) and tested its psychometric properties with 77 family members of intensive care patients. Compared with the original instrument, the construct validity of the German ICE-FPSQ (FPSQ-G) showed unstable results with a partially divergent structure, most likely caused by the limited sample size. The first two principal components explained 61% of the overall variance and a good internal consistency with a Cronbach's alpha of .92. The FPSQ-G is a promising instrument to measure family members' perceptions of the support they received from nurses in the acute critical care setting but requires further validation.

2024 Focused Update: Guidelines on Use of Corticosteroids in Sepsis, Acute Respiratory Distress Syndrome, and Community-Acquired Pneumonia

RATIONALE

New evidence is available examining the use of corticosteroids in sepsis, acute respiratory distress syndrome (ARDS) and community-acquired pneumonia (CAP), warranting a focused update of the 2017 guideline on critical illness-related corticosteroid insufficiency.

OBJECTIVES

To develop evidence-based recommendations for use of corticosteroids in hospitalized adults and children with sepsis, ARDS, and CAP.

PANEL DESIGN

The 22-member panel included diverse representation from medicine, including adult and pediatric intensivists, pulmonologists, endocrinologists, nurses, pharmacists, and clinician-methodologists with expertise in developing evidence-based Clinical Practice Guidelines. We followed Society of Critical Care Medicine conflict of interest policies in all phases of the guideline development, including task force selection and voting.

METHODS

After development of five focused Population, Intervention, Control, and Outcomes (PICO) questions, we conducted systematic reviews to identify the best available evidence addressing each question. We evaluated the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach and formulated recommendations using the evidence-to-decision framework.

RESULTS

In response to the five PICOs, the panel issued four recommendations addressing the use of corticosteroids in patients with sepsis, ARDS, and CAP. These included a conditional recommendation to administer corticosteroids for patients with septic shock and critically ill patients with ARDS and a strong recommendation for use in hospitalized patients with severe CAP. The panel also recommended against high dose/short duration administration of corticosteroids for septic shock. In response to the final PICO regarding type of corticosteroid molecule in ARDS, the panel was unable to provide specific recommendations addressing corticosteroid molecule, dose, and duration of therapy, based on currently available evidence.

CONCLUSIONS

The panel provided updated recommendations based on current evidence to inform clinicians, patients, and other stakeholders on the use of corticosteroids for sepsis, ARDS, and CAP.

Questions From Family Members During the Dying Process And Moral Distress Experienced by ICU Nurses

BACKGROUND

For a hospitalized patient, transitioning to comfort measures only (CMO) involves discontinuation of life-prolonging interventions with a goal of allowing natural death. Nurses play a pivotal role during the provision of CMO, caring for both the dying patient and their family.

OBJECTIVE

To examine the experiences of ICU nurses caring for patients receiving CMO.

METHODS

Between October 2020 and June 2021, nurses in the neuro- and medical-cardiac intensive care units at Harborview Medical Center in Seattle, WA, completed surveys about their experiences providing CMO. Surveys addressed involvement in discussions about CMO and questions asked by family members of dying patients. We also assessed nurses' moral distress related to CMO and used ordinal logistic regression to examine predictors of moral distress.

RESULTS

Surveys were completed by 82 nurses (response rate 44%), with 79 (96%) reporting experience providing CMO in the previous year. Most preferred to be present for discussions between physicians or advanced practice providers and family members about transitioning to CMO (89% most of the time or always); however, only 31% were present most of the time or always. Questions from family about time to death, changes in breathing, and medications to relieve symptoms were common. Most nurses reported moral distress at least some of the time when providing CMO (62%). Feeling well-prepared to answer specific questions from family was associated with less moral distress.

CONCLUSION

There is discordance between nurses' preferences for inclusion in discussions about the transition to CMO and their actual presence. Moral distress is common for nurses when providing CMO and feeling prepared to answer questions from family members may attenuate distress.

Photobiomodulation therapy (red/NIR LEDs) reduced the length of stay in intensive care unit and improved muscle function: A randomized, triple-blind, and sham-controlled trial

CONTEXT

Photobiomodulation therapy (PBMT) has been widely used to improve strength, fatigue resistance and increase muscle mass in healthy individuals. These effects could help critically ill patients admitted to intensive care units (ICUs) who show reduced mobility and muscle strength. ICU-acquired weakness lessens overall health and increases the patient's length of stay in the ICU.

OBJECTIVE

This study evaluated the effects of PBMT using low intensity light-emitting diodes (LEDs) on the mobility and muscle strength (functional capacity) and length of stay of patients admitted to hospital ICU.

METHODS

This randomized, triple-blind, sham-controlled trial was conducted in a hospital ICU. Sixty patients were randomly assigned to two equal groups: (a) PBMT and (b) Sham. PBMT was applied daily to patients until their discharge from the ICU, using a flexible neoprene array of 264 LEDs (120 at 635 nm, 1.2 mW each; 144 at 880 nm, 15 mW each) for 90s (207.36 Joules) at each site. Ten sites were located bilaterally on the thighs, legs, arms, and forearms ventrally and dorsally, 15 min totaling 2,073.6 Joules per session. Outcomes were length of stay (in h) until discharge from the ICU, muscle strength by the Medical Research Council (MRC) score and handgrip dynamometry (HGD), patient mobility by Intensive Care Unit Mobility Scale (IMS) and the Simplified Acute Physiology Score 3 (SAPS 3) for predicting mortality of patients admitted to the ICU.

RESULTS

PBMT reduced the average length of stay in the ICU by ~30% (p = 0.028); increased mobility (IMS: 255% vs. 110% p = 0.007), increased muscle strength (MRC: 12% vs. -9% p = 0.001) and HGD (34% vs. -13% p < 0.001), and the SAPS3 score was similar (p > 0.05).

CONCLUSION

The results suggest that daily PBMT can reduce the length of stay of ICU patients and increase muscle strength and mobility.

Factors associated with fever after cardiac arrest: A post-hoc analysis of the FINNRESUSCI study

BACKGROUND

Fever after cardiac arrest may impact outcome. We aimed to assess the incidence of fever in post-cardiac arrest patients, factors predicting fever and its association with functional outcome in patients treated without targeted temperature management (TTM).

METHODS

The FINNRESUSCI observational cohort study in 2010-2011 included intensive care unit (ICU)-treated out-of-hospital cardiac arrest (OHCA) patients from all five Finnish university hospitals and 14 of 15 central hospitals. This post hoc analysis included those FINNRESUSCI study patients who were not treated with TH. We defined fever as at least one temperature measurement of ≥37.8°C within 72 h of ICU admission. The primary outcome was favourable functional outcome at 12 months, defined as cerebral performance category (CPC) of 1 or 2. Binary logistic regression models including witnessed arrest, bystander cardiopulmonary resuscitation (CPR), initial rhythm and delay of return of spontaneous circulation were used to compare the functional outcomes of the groups.

RESULTS

There were 67,428 temperature measurements from 192 patients, of whom 89 (46%) experienced fever. Twelve-month CPC was missing in 7 patients, and 51 (28%) patients had favourable functional outcome at 12 months. The patients with shockable initial rhythms had a lower incidence of fever within 72 h of ICU admission (28% vs. 72%, p < .01), and the patients who experienced fever had a longer median return of spontaneous circulation (ROSC) delay (20 [IQR 10-30] vs. 14 [IQR 9-22] min, p < .01). Only initial non-shockable rhythm (OR 2.99, 95% CI 1.51-5.94) was associated with increased risk of fever within the first 72 h of ICU admission. Neither time in minutes nor area (minutes  ×  degree celsius over threshold) over 37°C, 37.5°C, 38°C, 38.5°C, 39°C, 39.5°C or 40°C were significantly different in those with favourable functional outcome compared to those with unfavourable functional outcome within the first 24, 48 or 72 h from ICU admission. Fever was not associated with favourable functional outcome at 12 months (OR 0.90, 95% CI 0.44-1.84).

CONCLUSIONS

Half of OHCA patients not treated with TTM developed fever. We found no association between fever and outcome.

Pain perception of patients in intensive care unit after cardiac surgery: A qualitative study using Roy's Adaptation Model

BACKGROUND

Although research on postoperative pain has increased, postoperative pain management is still a problem today. Most patients experience moderate to severe pain after cardiac surgery. As a result of pain, patients show inefficient adaptation behaviour in physiologic, role function, self-concept, and interdependence modes.

AIM

This study was conducted to examine the pain perceptions of intensive care patients after cardiac surgery according to Roy's Adaptation Model (RAM).

STUDY DESIGN

A qualitative design with a phenomenological approach was used in the study. The research data were collected by using a "descriptive information form", a "semi-structured interview form", and the "numerical rating scale" through the "in-depth interview method". The study sample consisted of 16 patients who were aged 18 years or older, had undergone cardiac surgery, experienced pain post-operatively in the intensive care unit at least once, and had intensive care experience. Patients with neuropathic or chronic pain or neurological or psychiatric disorders were not included in the study. Data were classified into physiologic, self-concept, and interdependence modes according to RAM.

RESULTS

The themes and sub-themes that emerged included physiologic modes (pain responses), self-concept modes (pain self-management), role-function modes (effects of pain), and interdependence modes (support systems in pain).

CONCLUSIONS

The results of our study can enable patients and nurses to communicate effectively about pain. In future studies, the effect of model-based pain management programs on cardiac surgery patients can be investigated.

RELEVANCE TO CLINICAL PRACTICE

Examining the pain perceptions of intensive care patients after cardiac surgery according to RAM will guide the improvement and development of pain management. It is thought that the model addresses intensive care patients experiencing pain holistically.

Effect of neuromuscular electrical stimulation and early physical activity on ICU-acquired weakness in mechanically ventilated patients: A randomized controlled trial

BACKGROUND

Intensive care unit-acquired weakness (ICU-AW) is common in critically ill patients and increases the duration of mechanical ventilation (MV) and weaning time. Early mobilization, range of motion (ROM) exercises, and neuromuscular electrical stimulation (NMES) can prevent ICU-AW by maintaining muscle mass. However, studies highlighting the effects of combining NMES with early physical activity in ICU patients are limited.

AIM

To evaluate the effect of NMES and early physical activity on ICU-AW in mechanically ventilated patients.

STUDY DESIGN

A single-blinded randomized controlled trial was conducted in Alexandria, Egypt. Patients were randomly assigned to one of four groups: NMES, ROM, combined therapy (ROM + NMES), or conventional care (control group). The Medical Research Council (MRC) scale was used to assess the ICU-AW for the study patients over a 7-day period. The duration of the patient's MV and ICU stays were recorded.

RESULTS

Of the 180 patients who were assessed for eligibility, 124 were randomly assigned to one of four groups: 32 patients in ROM exercises, 30 in NMES, 31 in combined therapy (ROM + NMES), and 31 in the control group. On day 7, ROM + NMES and NMES groups showed higher MRC scores than ROM and control groups (50.37 ± 2.34, 49.77 ± 2.19, 44.97 ± 3.61, and 41.10 ± 3.84, respectively). ANOVA test results indicated significant differences (p < .001) across the four groups. ICU-AW occurred in 0% of the ROM + NMES group, 60% of the ROM group, 13% of the NMES group, and 100% of the control group (p < .001). The MV duration (in days) in the ROM + NMES group was shorter (12.80 ± 3.800) than in the ROM, NMES, or control groups (21.80 ± 4.460, 18.73 ± 4.748, and 20.70 ± 3.932, respectively). ICU-LOS was shorter in the ROM + NMES group (17.43 ± 3.17 days) compared with the ROM group (22.53 ± 4.51 days), the NMES group (21.10 ± 5.0 days), and the control group (21.50 ± 4.42 days) with significant differences (p < .001) between the four groups.

CONCLUSION

Daily sessions of NMES and early physical activity were well tolerated, preserved muscle strength, prevented ICU-AW, and decreased the duration of the MV and ICU stay.

RELEVANCE TO CLINICAL PRACTICE

The findings of this study support the use of NMES and early physical exercises by critical care nurses as part of routine care for critically ill patients.

Family-Oriented Therapeutic Conversations: A Systematic Scoping Review

There is increasing evidence that highlights the benefits of Family-oriented Therapeutic Conversations (FAM-TC) for the patient and the family; however, studies show variability regarding the content and the way these interventions are offered. This may hamper its further development in clinical practice. This review systematically maps the available literature on nurse-led FAM-TC and offers a solid synthesis of the characteristic, effectiveness, and feasibility of these interventions. A systematic search in PubMed, CINAHL, Cochrane, Web of Science, PsycINFO, Trip (Turning Research Into Practice), BASE (Bielefeld Academic Search Engine), OATD (Open Access Theses and Dissertations), and ProQuest databases identified 37 studies. The interventions varied in interventionist nurses' profile, the intervention content, or the duration of the sessions offered. Most of the interventions showed beneficial effects on perceived family support and family functioning. This review offers suggestions for future studies, such as the inclusion of specific theoretical frameworks for intervention design, targeting both the patient and the family and offered by nurses with family nursing competency.

Turnover Rates and Factors Associated With Turnover: A Longitudinal Analysis of the Retention Period of Clinical Nurses in Korea Using National Data

Many countries, including Korea, are struggling with a nursing workforce shortage. This study aimed to identify the actual turnover rate of Korean clinical nurses and the factors affecting the turnover rate, considering the time required for nurses to gain experience at their current medical institution. This longitudinal study followed up on a cohort consisting of all 107,682 nurses from January 1, 2017 to July 30, 2020. Differences in the distribution of retention and turnover according to the medical institutions' and nurses' characteristics were analyzed using the chi-square test. The hazard ratios (HRs) for turnover in each analysis interval were analyzed using multilevel Cox proportional-hazards analysis. The mean turnover rate was 10.0% within 1 year and 33.4% within 3.5 years. Several organizational characteristics (the type and ownership of the hospital, its location, and the bed-to-nurse ratio) and individual characteristics (gender, age, and clinical experience) were found to be associated with turnover risk. Among these factors, compared to hospitals with a bed-to-nurse ratio in general wards of 6.0 or more, those with a ratio of 3.5-3.9 had an HR for 1-year turnover of 0.81 (95% confidence interval [CI]  =  0.67-0.98), and those with a ratio of 2.5-2.9 had an HR for 3.5-year turnover of 0.77 (95% CI  =  0.66-0.90). The bed-to-nurse ratio is a condition that can be modified through collaboration between government policy-makers and medical institutions. To reduce nurse turnover and retain experienced nurses, appropriate staffing should be implemented.

Does it matter who performs blood culture collection? Results of a survey assessing phlebotomist, nurse, and resident knowledge of blood culture collection protocols

Blood cultures are the primary method for diagnosing bloodstream infections. However, blood culture contamination (BCC) can lead to unnecessary antibiotic treatment, additional tests, and extended patient time in the hospital. The aim of this quality improvement project was to evaluate healthcare workers' knowledge of blood culture collection protocols and evaluate the blood culture contamination rates of laboratory and non-laboratory staff. We performed a retrospective review of contaminated cultures between May 2021 and April 2022, and anonymous surveys were distributed to assess staff knowledge of proper blood culture collection protocols. Laboratory staff (phlebotomy) had an overall BCC rate of 4.6% compared to a non-laboratory staff (nurses, residents, and medical students) rate of 9.7% (p < 0.0001). On the survey, phlebotomists had the best score (89% correct), followed by nurses (76%) and residents and medical students (64%). These data suggest that blood culture protocol knowledge and BCC rates may be related, with phlebotomists scoring highest on the knowledge survey and demonstrating the lowest contamination rates.

Feasibility, safety, and patient acceptability of electronic inspiratory muscle training in patients who require prolonged mechanical ventilation in the intensive care unit: A dual-centre observational study

BACKGROUND

Inspiratory muscle training (IMT) is an intervention that can be used to rehabilitate the respiratory muscle deconditioning experienced by patients with critical illness, requiring prolonged mechanical ventilation. Clinicians are currently using mechanical threshold IMT devices that have limited resistance ranges.

OBJECTIVES

The objective of this study was to evaluate the safety, feasibility, and acceptability of using an electronic device to facilitate IMT with participants requiring prolonged mechanical ventilation.

METHOD

A dual-centre observational cohort study, with convenience sampling, was conducted at two tertiary intensive care units. Daily training supervised by intensive care unit physiotherapists was completed with the electronic IMT device. A priori definitions for feasibility, safety, and acceptability were determined. Feasibility was defined as more than 80% of planned sessions completed. Safety was defined as no major adverse events and less than 3% minor adverse event rate, and acceptability was evaluated following the acceptability of intervention framework principles.

RESULTS

Forty participants completed 197 electronic IMT treatment sessions. Electronic IMT was feasible, with 81% of planned sessions completed. There were 10% minor adverse events and no major adverse events. All the minor adverse events were transient without clinical consequences. All the participants who recalled completing electronic IMT sessions reported that the training was acceptable. Acceptability was demonstrated; over 85% of participants reported that electronic IMT was either helpful or beneficial and that electronic IMT assisted their recovery.

CONCLUSION

Electronic IMT is feasible and acceptable to complete with critically ill participants who require prolonged mechanical ventilation. As all minor adverse events were transient without clinical consequences, electronic IMT can be considered a relatively safe intervention with patients who require prolonged mechanical ventilation.
