Transferring the critically ill patient: are we there yet?

Interfacility transfer of the critically ill: Transfer status does not influence survival

PURPOSE

To estimate differences in case-mix adjusted hospital mortality between adult ICU patients who are transferred during their ICU-stay and those who are not.

METHODS

19,260 visits to 12 ICUs in Nova Scotia (NS), Canada April 2018-September 2023 were analyzed. Data were obtained from the NS Provincial ICU database. Generalized additive models (GAMs) were used to estimate differences in case-mix adjusted hospital mortality between patients who underwent transfer and those who did not.

RESULTS

1040/19,260 (5%) ICU visits involved interfacility-transfer. No difference in hospital mortality was identified between transferred and non-transferred patients by GAM (OR, 0.99, 95% CI, 0.82 to 1.19; p = 0.91). No mortality difference was observed between patients undergoing a single transfer versus multiple (OR, 0.87; 95% CI, 0.45 to -1.69; p = 0.68). A GAM including the categories no transfer, one transfer, and multiple transfers identified a difference in hospital mortality for patients that underwent multiple transfers compared to non-transferred patients (OR, 0.68; 95% CI, 0.46 to 1.00, p = 0.05), but no difference was identified in a post-hoc matched cohort sensitivity analysis (OR, 0.68; 95% CI, 0.46 to 1.01, p = 0.05).

CONCLUSION

The transfer of critically ill patients between ICUs in Nova Scotia did not impact case-mix adjusted hospital mortality.

Inter hospital transfers in rotor wing aircraft. Patterns and challenges. Protocol for a scoping review

BACKGROUND

Inter-hospital transfer is necessary for the transport of patients to specialized treatment. Rotor-wing aircraft may be used in lieu of ambulances in time-critical conditions over long distances and when specialist team skills are called for. The purpose of the review is to assess the current scientific literature that describes the scenario to develop a national guideline for inter-hospital transfers using rotor-wing aircraft. The aim is to describe the patterns and challenges.

METHODS AND ANALYSIS

The authors will conduct a scoping review as per Joanna Briggs Institute guideline. The protocol for the scoping review will adhere to the Open Science Framework guideline for scoping reviews and we will report the findings of the scoping review as per PRISMA-ScR guideline. We have developed the search strategy with the help of a research librarian and will conduct search in relevant electronic databases and include gray literature as well, using the PRESS and PRISMA-S guidelines. Two authors will independently screen titles and abstracts for inclusion as per eligibility criteria and conflicts will be resolved by a third reviewer. Full text retrieval will be conducted accordingly. We will analyze the extracted data using validated statistical methods.

ETHICS AND DISSEMINATION

According to Danish law, scoping reviews are exempt from ethics committee approval. The findings of this scoping review will provide the scientific foundation for a national guideline on rotor-wing aircraft conveyed inter-hospital transfers in Denmark. Furthermore, we will publish the results of the scoping review in a relevant scientific journal.

Psychological safety in an ECMO retrieval team: a qualitative study to inform improvement

INTRODUCTION

In healthcare teams, psychological safety is associated with improved performance, communication, collaboration and patient safety. Extracorporeal membrane oxygenation (ECMO) retrieval teams are multidisciplinary teams that initiate ECMO therapy for patients with severe acute respiratory failure in referring hospitals and transfer patients to regional specialised centres for ongoing care. The present study aimed to explore an ECMO team's experience of psychological safety and generate recommendations to strengthen psychological safety.

METHODS

The study was conducted in the Royal Brompton Hospital (RBH), part of Guy's and St Thomas' NHS Foundation Trust in London. RBH is one of six centres commissioned to provide ECMO therapy in the UK. 10 participants were recruited: 2 consultants, 5 nurses and 3 perfusionists. Semistructured interviews were used to explore the team members' views on teamwork, their perceived ability to discuss concerns within the team and the interaction between speaking up, teamwork and hierarchy. A Reflexive Thematic Analysis approach was used to explore the interview data.

RESULTS

The analysis of the interview dataset identified structural and team factors shaping psychological safety in the specific context of the ECMO team. The high-risk environment in which the team operates, the clearly defined process and functions and the structured opportunities that provide legitimate moments to reflect together influence how psychological safety is experienced. Furthermore, speaking up is shaped by the familiarity among team members, the interdependent work, which requires boundary spanning across different roles, and leadership behaviour. A hierarchy of expertise is privileged over traditional institutional ranking.

CONCLUSION

This study surfaced the structural and team factors that influence speaking up in the specific context of an ECMO retrieval team. Such information is used to suggest interventions to improve and strengthen psychological safety.

Evaluating the learning curve of endoscopic surgery for spontaneous intracerebral hemorrhage: A single-center experience in a county hospital

BACKGROUND

Endoscopic surgery has shown promise in treating Spontaneous Intracerebral Hemorrhage (sICH), but its adoption in county-level hospitals has been hindered by the high level of surgical expertise required.

METHODS

In this retrospective study at a county hospital, we utilized a Cumulative Sum (CUSUM) control chart to visualize the learning curve for two neurosurgeons. We compared patient outcomes in the learning and proficient phases, and compared them with expected outcomes based on ICH score and ICH functional outcome score, respectively.

RESULTS

The learning curve peaked at the 12th case for NS1 and the 8th case for NS2, signifying the transition to the proficient stage. This stage saw reductions in operation time, blood loss, rates of evacuation < 90 %, rebleeding rates, intensive care unit stay, hospital stay, and overall costs for both neurosurgeons. In the learning stage, 6 deaths occurred within 30 days, less than the 10.66 predicted by the ICH score. In the proficient stage, 3 deaths occurred, less than the 15.88 predicted. In intermediate and high-risk patients by the ICH functional outcome score, the proficient stage had fewer patients with an mRS ≥ 3 at three months than the learning stage (23.8 % vs. 69.2 %, P = 0.024; 40 % vs. 80 %, P = 0.360). Micromanipulating bipolar precision hemostasis and aspiration devices in the endoport's channels sped up the transition from learning to proficient.

CONCLUSION

The data shows a learning curve, with better surgical outcomes as surgeons gain proficiency. This suggests cost benefits of surgical proficiency and the need for ongoing surgical education and training in county hospitals.

Unit-to-unit transfer due to shortage of intensive care beds in Sweden 2015-2019 was associated with a lower risk of death but a longer intensive care stay compared to no transfer: a registry study

BACKGROUND

Intensive care unit-to-unit transfer due to temporary shortage of beds is increasing in Sweden. Transportation induces practical hazards, and the change of health care provider may prolong the length of stay in intensive care. We previously showed that the risk of death at 90 days did not differ between patients transferred due to a shortage of beds and non-transferred patients with a similar burden of illness in a tertiary intensive care unit. The aim of this study was to widen the analysis to a nation-wide cohort of critically ill patients transferred to another intensive care unit in Sweden due to shortage of intensive care beds.

METHODS

Retrospective comparison between capacity transferred and non-transferred patients, based on data from the Swedish Intensive Care Registry during a 5-year period before the COVID-19 pandemic. Patients with insufficient data entries or a recurring capacity transfer within 90 days were excluded. To assess the association between capacity transfer and death as well as intensive care stay within 90 days after ICU admission, logistic regression models with step-wise adjustment for SAPS3 score, primary ICD-10 ICU diagnosis and the number of days in the intensive care unit before transfer were applied.

RESULTS

From 161,140 eligible intensive care admissions, 2912 capacity transfers were compared to 135,641 discharges or deaths in the intensive care unit. Ninety days after ICU admission, 28% of transferred and 21% of non-transferred patients were deceased. In the fully adjusted model, capacity transfer was associated with a lower risk of death within 90 days than no transfer; OR (95% CI) 0.71 (0.65-0.69) and the number of days spent in intensive care was longer: 12.4 [95% CI 12.2-12.5] vs 3.3 [3.3-3.3].

CONCLUSIONS

Intensive care unit-to-unit transfer due to shortage of bed capacity as compared to no transfer during a 5-year period preceding the COVID-19 pandemic in Sweden was associated with lower risk of death within 90 days but with longer stay in intensive care.

[The SCATTER project: computer-based simulation in the strategic transfer of intensive care patients]

BACKGROUND

The need for a concept for the nationwide strategic transfer of critical care patients in Germany was highlighted during the COVID-19 (coronavirus disease 2019) pandemic. Despite the cloverleaf concept developed specifically for this purpose, the transfer of large numbers of critical care patients represents a major challenge. With the help of a computer simulation, the SCATTER research project uses a fictitious example to test, develop, and recommend transfer strategies.

METHOD

The simulation was programmed after collecting procedural and structural data on critical care transports within Germany. The simulation allows altering various parameters and testing different transfer scenarios. In a fictitious scenario, nationwide transfers starting from Schleswig-Holstein were simulated and evaluated using predetermined criteria.

RESULTS

In the case of ground-based transfers, it became apparent that, depending on the selected target region, not all patients could be transferred due to the limited range of ground-based vehicles. Although a higher number of patients can be transferred by air, this is associated with additional gurney changes and potential risk to the patient. A distance-dependent transport strategy led to the identical results as purely air-bound transport, since air-bound transport was always chosen due to the long distances.

DISCUSSION

The simulation can be used to develop recommendations and to draw important conclusions from different transfer strategies.

A retrospective observational study of vCare: a virtual emergency clinical advisory and transfer service in rural and remote Australia

BACKGROUND

Provision of critical care in rural areas is challenging due to geographic distance, smaller facilities, generalist skill mix and population characteristics. Internationally, the amalgamation telemedicine and retrieval medicine services are developing to overcome these challenges. Virtual emergency clinical advisory and transfer service (vCare) is one of these novel services based in New South Wales, Australia. We aim to describe patient encounters with vCare from call initiation at the referring site to definitive care at the accepting site.

METHODS

This retrospective observational study reviewed all patients using vCare in rural and remote Australia for clinical advice and/or inter-hospital transfer for higher level of care between February and March 2021. Data were extracted from electronic medical records and included remoteness of sites, presenting complaint, triage category, camera use, patient characteristics, transfer information, escalation of therapeutic intervention and outcomes. Data were summarised using cross tabulation.

RESULTS

1,678 critical care patients were supported by vCare, with children (12.5%), adults (50.6%) and older people (36.9%) evenly split between sexes. Clinicians mainly referred to vCare for trauma (15.1%), cardiac (16.1%) and gastroenterological (14.8%) presentations. A referral to vCare led to an escalation of invasive intervention, skill, and resources for patient care. vCare cameras were used in 19.8% of cases. Overall, 70.5% (n = 1,139) of patients required transfer. Of those, 95.1% were transferred to major regional hospitals and 11.7% required secondary transfer to higher acuity hospitals. Of high-urgency referrals, 42.6% did not receive high priority transport. Imaging most requested included CT and MRI scans (37.2%). Admissions were for physician (33.1%) and surgical care (23.3%). The survival rate was 98.6%.

CONCLUSION

vCare was used by staff in rural and remote facilities to support decision making and care of patients in a critical condition. Issues were identified including low utilisation of equipment, heavy reliance on regional sites and high rates of secondary transfer. However, these models are addressing a key gap in the health workforce and supporting rural and remote communities to receive care.

Developing key performance indicators for adult critical care transfer services: Scoping review and Delphi technique

In 2021 NHS England commissioned regional Adult Critical Care Transfer Services. These services will replace a historically predominant ad hoc approach to adult critical care transfers nationally. It is anticipated that these new formal services will provide a system of robust regional & national governance previously acknowledged to be deficient. As part of this process, it is important that an agreed set of transfer service quality indicators are developed to drive equitable improvement in patient care. We used a Delphi technique to develop a set of key performance indicators through consensus for a recently established London critical care transfer service. We believe this may be the first-time key performance indicators have been developed for adult critical care transfer services using a consensus method. We hope services will consider tracking similar measures to enable benchmarking and drive improvements in patient care.

Overcoming distance: an exploration of current practices of government and charity-funded critical care transport and retrieval organizations

BACKGROUND

For critically ill and injured patients, timely access to definitive care is associated with a reduction in avoidable mortality. Access to definitive care is significantly affected by geographic remoteness. To overcome this disparity, a robust critical care transport (CCT) or retrieval system is essential to support the equity of care and overcome the tyranny of distance. While critical care transport or retrieval systems have evolved over the years, there is no universally accepted system or standard, which has led to considerable variation in practices. The objective of this mixed-methods study was to identify and explore the current clinical, operational, and educational practices of government and charity-funded critical care transport and retrieval organizations operating across access- and weather- challenged geography.

METHODS

This study utilized a mixed-methods approach comprising a rapid review of the literature and semi-structured interviews with identified subject matter experts (SME).

RESULTS

A total of 44 articles and 14 interviews with SMEs from six different countries, 12 different services/systems, and seven operational roles, including clinicians (physician, paramedic, and nurse), educator, quality improvement, clinical governance, clinical informatics and research, operations manager, and medical director were included in the narrative analysis. The study identified several themes including deployment, crew composition, selection and education, clinical governance, quality assurance and quality improvement and research.

CONCLUSION

This mixed-methods study underscores the paucity of literature describing current clinical, operational, and educational practices of government or charity-funded CCT or retrieval programs operating across access- and weather- challenged geography. While many common themes were identified including clearly defined mission profiles, use of dedicated or specialized transport teams, central coordination, rigorous selection processes, service-sponsored graduate education, and strong clinical governance, there is little consensus and considerable variation in current practices. Further research is needed to identify and harmonize best practices within the CCT and retrieval environments.

A national retrospective descriptive analysis of critical care transfers in the private sector in South Africa

BACKGROUND

Critical care transfers (CCTs) are necessitated by the growing prevalence of high-acuity patients who require upgrade of care to multidisciplinary teams from less-equipped referring facilities. Owing to the high acuity of the critical care patient, specialised teams with advanced training and equipment are called upon to undertake these transfers. The inherent understanding of the potential effects, and therefore the needs of the critical care patient during transfer, are affected owing to the paucity of international, but more specifically, local data relating to CCTs.

OBJECTIVES

To describe a cohort of patients who underwent CCT by dedicated critical care retrieval services (CCRS) in the private sector in South Africa (SA).

METHODS

This retrospective, descriptive study sampled all paediatric and adult CCTs completed over a 1-year period (1 January 2017 - 31 December 2017) from the dedicated CCRS of two national emergency medical services in SA. All neonatal patients were excluded. Data were extracted from patient report forms by trained data extractors and subjected to descriptive analysis.

RESULTS

A total of 1 839 patients were transferred between the two services. A total of 3 143 diagnoses were recorded, yielding an average of ~2 diagnoses per patient. The most prevalent primary diagnosis was cardiovascular disease (n=457, 25%), followed by infection (n=180, 10%) and head injury (n=133, 7%). Patients had an average of ~3 attachments, with the most prevalent being patient monitoring (n=2 856, 155%), peripheral intravenous access (n=794, 43%) and mechanical ventilation (n=445, 24%). A total of 2 152 instances of medication infusion or administration were required during transport, yielding an average of ~1 medication or infusion per patient transported. The most common medications recorded were central nervous system depressants (n=588, 32%), followed by analgesics (n=482, 26%) and inotropic or vasoactive agents (n=320, 17%).

CONCLUSION

This study provides insight into the demographics, most prevalent diagnoses and interfacility transfer monitoring needs of patients being transported in SA by two private dedicated CCRS. The results of this study may be used to inform future specialised critical care transport courses and qualifications, equipment procurement and scopes of practice for providers undertaking critical care transfers.

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

Background

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

Objectives

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

Methods

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

Results

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

Conclusion

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

Contributions of the study

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

Telehealth consultation before inter-hospital transfer after falls in a subacute hospital (the PREVENT-2 study)

OBJECTIVE

Inter-hospital transfers are increasingly common due to the regionalisation of healthcare, but are associated with patient discomfort, high costs and adverse events. The aim of the present study was to evaluate the effectiveness of a trauma outreach service for preventing inter-hospital transfers to a major trauma centre.

METHODS

This was an observational pre- and post-intervention study over a 12-month period from 1 October 2020 to 30 September 2021. Eligible patients sustained a fall at Caulfield Hospital, a subacute care hospital specialising in community services, rehabilitation, geriatric medicine and aged mental health. The intervention was delivery of site-specific education at Caulfield Hospital and a trauma outreach service by specialist trauma clinicians at The Alfred Hospital who provided remote assessment, assisted with clinical management decisions and advised on appropriateness of transfer.

RESULTS

The present study included 160 patients in the pre-intervention phase and 203 after the intervention. The primary outcome of transfer occurred in 19 (11.9%) patients in the pre-intervention phase and 4 (2.0%) in the post-intervention phase (P < 0.001). In the subgroup of patients without pelvis or long bone fractures, pre-intervention transfer occurred for 17 (10.9%) patients and post-intervention transfer occurred for 4 (2.0%) patients (P < 0.001). CT imaging was performed for 54 (33.8%) patients in the pre-intervention and 45 (22.2%) patients in the post-intervention group (P = 0.014).

CONCLUSIONS

Telehealth consultation with a trauma specialist was associated with significant reduction of inter-hospital transfers, and significant reduction of CT imaging. This supports continuation of the service with scope for expansion and evaluation of patient-centred outcomes.

Urgent hospital transfers - The experiences and required skills of paramedics

INTRODUCTION

Global changes in the health and social care sector have centralized the treatment of emergency patients, leading to an increase of urgent hospital transfers. The aim of this study is to describe paramedics' experiences gained while working in prehospital emergency care, regarding urgent hospital transfers and the skills that performing urgent hospital transfers requires.

METHODS

Twenty paramedics with experience in urgent hospital transfers participated in this qualitative study. The data collected via individual interviews were analyzed using inductive content analysis.

RESULTS

Paramedics' experiences of urgent hospital transfers resulted in two upper categories: Factors related to paramedics, and factors related to transfer, conditions, and technology. The upper categories were grouped from six subcategories. Paramedics' experiences of skills required in urgent hospital transfers resulted in two upper categories: Professional competence, and interpersonal skills. The upper categories were grouped from six subcategories.

CONCLUSIONS

Organizations should support and promote training related to urgent hospital transfers to enhance the quality of care and patient safety. Paramedics play a key role in successful transfer and collaboration, and thus the required professional competences and interpersonal skills should be addressed in their education. Furthermore, developing standardized procedures is recommended to enhance patient safety.

Interfacility Transport of Critically Ill Patients

OBJECTIVES

To assess recent advances in interfacility critical care transport.

DATA SOURCES

PubMed English language publications plus chapters and professional organization publications.

STUDY SELECTION

Manuscripts including practice manuals and standard (1990-2021) focused on interfacility transport of critically ill patients.

DATA EXTRACTION

Review of society guidelines, legislative requirements, objective measures of outcomes, and transport practice standards occurred in work groups assessing definitions and foundations of interfacility transport, transport team composition, and transport specific considerations. Qualitative analysis was performed to characterize current science regarding interfacility transport.

DATA SYNTHESIS

The Task Force conducted an integrative review of 496 manuscripts combined with 120 from the authors' collections including nonpeer reviewed publications. After title and abstract screening, 40 underwent full-text review, of which 21 remained for qualitative synthesis.

CONCLUSIONS

Since 2004, there have been numerous advances in critical care interfacility transport. Clinical deterioration may be mitigated by appropriate patient selection, pretransport optimization, and transport by a well-resourced team and vehicle. There remains a dearth of high-quality controlled studies, but notable advances in monitoring, en route management, transport modality (air vs ground), as well as team composition and training serve as foundations for future inquiry. Guidance from professional organizations remains uncoupled from enforceable regulations, impeding standardization of transport program quality assessment and verification.

Safety during interhospital helicopter transfer of ventilated COVID-19 patients. No clinical relevant changes in vital signs including non-invasive cardiac output

Background

During the COVID-19 pandemic in The Netherlands, critically ill ventilated COVID-19 patients were transferred not only between hospitals by ambulance but also by the Helicopter Emergency Medical Service (HEMS). To date, little is known about the physiological impact of helicopter transport on critically ill patients and COVID-19 patients in particular. This study was conducted to explore the impact of inter-hospital helicopter transfer on vital signs of mechanically ventilated patients with severe COVID-19, with special focus on take-off, midflight, and landing.

Methods

All ventilated critically ill COVID-19 patients who were transported between April 2020 and June 2021 by the Dutch ‘Lifeliner 5’ HEMS team and who were fully monitored, including noninvasive cardiac output, were included in this study. Three 10-min timeframes (take-off, midflight and landing) were defined for analysis. Continuous data on the vital parameters heart rate, peripheral oxygen saturation, arterial blood pressure, end-tidal CO₂ and noninvasive cardiac output using electrical cardiometry were collected and stored at 1-min intervals. Data were analyzed for differences over time within the timeframes using one-way analysis of variance. Significant differences were checked for clinical relevance.

Results

Ninety-eight patients were included in the analysis. During take-off, an increase was noticed in cardiac output (from 6.7 to 8.2 L min⁻¹; P < 0.0001), which was determined by a decrease in systemic vascular resistance (from 1071 to 739 dyne·s·cm⁻⁵, P < 0.0001) accompanied by an increase in stroke volume (from 88.8 to 113.7 mL, P < 0.0001). Other parameters were unchanged during take-off and mid-flight. During landing, cardiac output and stroke volume slightly decreased (from 8.0 to 6.8 L min⁻¹, P < 0.0001 and from 110.1 to 84.4 mL, P < 0.0001, respectively), and total systemic vascular resistance increased (P < 0.0001). Though statistically significant, the found changes were small and not clinically relevant to the medical status of the patients as judged by the attending physicians.

Conclusions

Interhospital helicopter transfer of ventilated intensive care patients with COVID-19 can be performed safely and does not result in clinically relevant changes in vital signs.

Response Time in the Transport of Pediatric Patients to a Tertiary Critical Care Unit

Introduction:

Various barriers delay the process of patient transfer to critical care units. We implemented quality improvement methods to decrease the time required for interhospital transfer of critical care patients. As a result, we aimed to decrease the time from initial transfer call to specialized transport team arrival at the referring hospital from 150 minutes to <40 minutes over 2 years.

Methods:

Quality improvement initiative monitoring the length of transport time of 245 patients transferred from referral hospitals to a tertiary pediatric intensive care unit for 31 months from March 2013 to October 2015. We reviewed preexisting transport protocols and identified barriers to the timely arrival to the pediatric intensive care unit. We implemented 3 interventions: a transport information line serving as a central communication center to coordinate the transport process between all stakeholders, the formation of a specialized pediatric transport team, and a training program. We collected transport response time data and monitored the impact of interventions via statistical process control charts.

Results:

There was a significant decrease in the length of the time course pre- and postintervention. We noted a special cause to decrease in time from referral hospital call to arrival of our transport team by 76% from 150 minutes to 36 minutes. In addition, the statistical process chart revealed a stable and effective process without significant shifts above the process mean as early as 3 months postintervention.

Conclusions:

By improving our transport services with additional resources and people, we have improved the efficiency of patient transport between institutions.

Intensive care unit to unit capacity transfers are associated with increased mortality: an observational cohort study on patient transfers in the Swedish Intensive Care Register

Background

Transfers from one intensive care unit (ICU) to another ICU are associated with increased length of intensive care and hospital stay. Inter-hospital ICU transfers are carried out for three main reasons: clinical transfers, capacity transfers and repatriations. The aim of the study was to show that different ICU transfers differ in risk-adjusted mortality rate with repatriations having the least risk.

Results

Observational cohort study of adult patients transferred between Swedish ICUs during 3 years (2016–2018) with follow-up ending September 2019. Primary and secondary end-points were survival to 30 days and 180 days after discharge from the first ICU. Data from 75 ICUs in the Swedish Intensive Care Register, a nationwide intensive care register, were used for analysis (89% of all Swedish ICUs), covering local community hospitals, district general hospitals and tertiary care hospitals. We included adult patients (16 years or older) admitted to ICU and subsequently discharged by transfer to another ICU. Only the first admission was used. Exposure was discharge to any other ICU (ICU-to-ICU transfer), whether in the same or in another hospital. Transfers were grouped into three predefined categories: clinical transfer, capacity transfer, and repatriation. We identified 15,588 transfers among 112,860 admissions (14.8%) and analysed 11,176 after excluding 4112 repeat transfer of the same individual and 300 with missing risk adjustment. The majority were clinical transfers (62.7%), followed by repatriations (21.5%) and capacity transfers (15.8%). Unadjusted 30-day mortality was 25.0% among capacity transfers compared to 14.5% and 16.2% for clinical transfers and repatriations, respectively. Adjusted odds ratio (OR) for 30-day mortality were 1.25 (95% CI 1.06–1.49 p = 0.01) for capacity transfers and 1.17 (95% CI 1.02–1.36 p = 0.03) for clinical transfers using repatriation as reference. The differences remained 180 days post-discharge.

Conclusions

There was a large proportion of ICU-to-ICU transfers and an increased odds of dying for those transferred due to other reasons than repatriation.

Respiratory and circulatory insufficiency during emergent long-distance critical care interhospital transports to tertiary care in a sparsely populated region: a retrospective analysis of late mortality risk

OBJECTIVES

To test if impaired oxygenation or major haemodynamic instability at the time of emergency intensive care transport, from a smaller admitting hospital to a tertiary care centre, are predictors of long-term mortality.

DESIGN

Retrospective observational study. Impaired oxygenation was defined as oxyhaemoglobin %-inspired oxygen fraction ratio (S/F ratio)<100. Major haemodynamic instability was defined as a need for treatment with norepinephrine infusion to sustain mean arterial pressure (MAP) at or above 60 mm Hg or having a mean MAP <60. Logistic regression was used to assess mortality risk with impaired oxygenation or major haemodynamic instability.

SETTING

Sparsely populated Northern Sweden. A fixed-wing interhospital air ambulance system for critical care serving 900 000 inhabitants.

PARTICIPANTS

Intensive care cases transported in fixed-wing air ambulance from outlying hospitals to a regional tertiary care centre during 2000-2016 for adults (16 years old or older). 2142 cases were included.

PRIMARY AND SECONDARY OUTCOME MEASURES

All-cause mortality at 3 months after transport was the primary outcome, and secondary outcomes were all-cause mortality at 1 and 7 days, 1, 6 and 12 months.

RESULTS

S/F ratio <100 was associated with increased mortality risk compared with S/F>300 at all time-points, with adjusted OR 6.3 (2.5 to 15.5, p<0.001) at 3 months. Major haemodynamic instability during intensive care unit (ICU) transport was associated with increased adjusted OR of all-cause mortality at 3 months with OR 2.5 (1.8 to 3.5, p<0.001).

CONCLUSION

Major impairment of oxygenation and/or major haemodynamic instability at the time of ICU transport to get to urgent tertiary intervention is strongly associated with increased mortality risk at 3 months in this cohort. These findings support the conclusion that these conditions are markers for many fold increase in risk for death notable already at 3 months after transport for patients with these conditions.

Interhospital transport of critically ill patients: A prospective observational study of patient and transport characteristics

BACKGROUND

The cohort of critically ill patients transported between Intensive Care Units (ICUs) in Norway has not been studied previously. The aim of this study was to describe the characteristics of patients and transports for different types of interhospital transfers and explore whether there were differences in morbidity and mortality between the different transfer categories and the general Norwegian ICU population.

METHODS

All transports of critically ill adult patients transferred between two geographically different Intensive Care Units during a one-year period were registered. Patient and transport data were obtained from The Norwegian Intensive Care Registry, The Norwegian Cause of Death Registry, the hospital Electronic Patient Journal, the Air Ambulance Journal System, and the Emergency Medical Communication Centre database.

RESULTS

821 transports of 788 surgical and medical patients were enrolled. Simplified Acute Physiology Scores (SAPSII) were 43, 36 and 38 for urgent secondary transport, non-urgent secondary transport and return transfers, respectively. These were comparable to nationwide SAPSII scores that were 40 for university hospitals and 34 for local hospitals during the same time period. The return transfers had a median SOFA-score of 4.7 and 53% were mechanically ventilated. Only 33% of return transfers were performed by established teams.

CONCLUSION

Intensive care patients transferred between ICUs are as critically ill as the rest of the ICU population, with a similar morbidity and mortality. The return transfers of ICU-patients appear under-triaged compared to secondary transports in terms of allocated resources.

Multiprofessional team interventions in transporting critically ill patients: a systematic mixed-methods review

ABSTRACT Aim To analyze how interventions of a multidisciplinary team promote the safe transportation of critically ill patients. Method A systematic mixed-methods review was developed using an integrated convergent approach according to the Joanna Briggs Institute. This study was conducted using MEDLINE, CINAHL, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials electronic databases, which generated 107 references. After removing duplicates and applying inclusion and exclusion criteria, 17 articles were evaluated for methodological quality, resulting in 15 articles as the final sample. Data extraction was performed using a tool in the form of a table and synthesized through thematic analysis. Results Thoughtful decision, planning, problem-solving action and action for improvement are interventions that the multiprofessional team promotes the safe transportation of critically ill patients. Conclusion and implications for practice The standardization of transport (institutional protocols, a checklist, and equipment adequacy), continuing education, and skills training in the capacitation of teams foster a culture of safety that prevents harm to the patient. Further research is suggested on the subjective dimension and with the family in transportation.

Is intensive care unit mortality a valid survival outcome measure related to critical illness?

RATIONALE

Use of death as an outcome of intensive care unit (ICU) admission may be biased by differential discharge decisions.

OBJECTIVE

To determine the validity of ICU survival status as an outcome measure of all cause case-fatality.

METHODS

A retrospective cohort of first admissions among adults to four ICUs in North Brisbane, Australia was assembled. Death in ICU (censored at discharge or 30 days) was compared with 30-day overall case-fatality.

RESULTS

The 30-day overall case-fatality was 8.1% (2436/29,939). One thousand six hundred and thirty-one deaths occurred within the ICU stay and 576 subsequent during hospital post-ICU discharge within 30-days; ICU and hospital case-fatality rates were 5.4% and 7.4%, respectively. An additional 229 patients died after hospital separation within 30 days of ICU admission of which 110 (48.0%) were transferred to another acute care hospital, 80 (34.9%) discharged home, and 39 (17.0%) transferred to an aged care/chronic care/rehabilitation facility. Patients who died after ICU discharge were older, had higher APACHE III scores, were more likely to be elective surgical patients, and were less likely to be out of state residents or managed in a tertiary referral hospital. Limiting determination of case-fatality to ICU information alone would correctly detect 95% (780/821) of all-cause mortality at day 3, 90% (1093/1213) at day 5, 75% (1524/2019) at day 15, 72% (1592/2244) at day 21, and 67% (1631/2436) at day 30 of follow-up.

CONCLUSIONS

Use of ICU case-fatality significantly underestimates the true burden and biases assessment of determinants of critical illness-related mortality in our region.

Incidents related to critical patient safety during in-hospital transfer

OBJECTIVE

To analyze the incidents related to patient safety (IRSP) and their risk factors during in-hospital transfer (IHT) of critical patients after the application of a protocol, and to evaluate safety during transfer using quality indicators.

DESIGN

A prospective, observational and non-intervention cohort study was carried out.

SETTING

A 10-bed multipurpose Intensive Care Unit (ICU) of a second level university hospital.

PATIENTS

All IHTs of critical patients in the ICU for diagnostic tests and to the operating room between March 2011 and March 2017 were included in the study.

MAIN MEASUREMENTS

Demographic variables, patient severity, transfer priority, moment of the day, reason and type of transfer team. Pre-transport checklist items and IRSP were collected. A biannual analysis was made of quality indicators designed for IHT.

RESULTS

A total of 805 transfers were registered, mostly of an urgent nature (53.7%) and for diagnostic tests (77%). In turn, 112 transfers (13.9%) presented some type of IRSP; 54% related to the equipment and 30% related to team and organization. Adverse events occurred in 19 (2.4%) transfers. Risk factors identified in the multivariate analysis were mechanical ventilation and the transport team. The evolution of the indicators related to transport was significantly favorable.

CONCLUSIONS

After the application of an IHT protocol, IRSP are low. The main risk factor is invasive mechanical ventilation. The experience of the team performing IHT influences the detection of a greater number of incidents.

Antibiotic Resistance Profile of Common Bacteria Isolated from Blood Stream, Lower Respiratory Tract and Urinary Infections in Intensive Care Unit in Saudi Arabia: A Retrospective Study

Background

The rate of infections in the intensive care units (ICUs) is rising, mainly because of the increasing use of invasive procedures and specialized devices. This study aimed to identify the antibiotic resistance profile of common bacteria isolated from lower respiratory tract infections (LRTIs), bloodstream infections (BSIs), and urinary infections (UTIs) in ICUs in Saudi Arabia.

Methods

In the current retrospective study, the isolates and antibiotic resistance were collected from the Electronic Medical Record (EMR) for respiratory, blood, and urine samples. The study sample compromised 96 patients admitted to the ICU at least for 48 hours and have a central venous catheter (CVC) between November 1, 2020, and January 31, 2021.

Results

66 (68.8%) of the study sample were males, and 30 (31.2%) were females. LRTIs were the most common isolates (51 samples), followed by BSIs (28 samples) and UTIs (17 samples). The isolated pathogens in this study were Klebsiella pneumoniae (K. pneumoniae) (59.4%), Coagulase-negative staphylococci (CoNS) (11.5%), Escherichia coli (E. coli) (8.4%), Acinetobacter baumannii (A. baumannii) (7.3%), and Staphylococcus aureus (S. aureus) (6.2%). BSI were frequently caused by CoNS (35.7%) and K. pneumoniae (35.7%), while Methicillin-resistant Staphylococcus aureus (MRSA) represented 10.7% of BSI. Vancomycin, Synercid, and Teicoplanin were the commonly used antibiotics and showed 100% sensitivity among S. aureus, including MRSA, while almost 100% resistance was observed for penicillin and oxacillin against the same organisms. The maximum resistance was observed with aztreonam (96.4%), ampicillin (87.3%), followed by co-amoxiclav (83.9%), cotrimoxazole (79.5%) and cephalosporin group antibiotics.

Conclusions

Strict adherence to infection prevention practices and wise use of antibiotics are recommended to slow the spread of antimicrobial resistance (AMR).

National Trends in Transfer of Patients with Primary Intracerebral Hemorrhage: An Analysis of 12-Year Nationwide Data

OBJECTIVES

The guidelines of the American Hospital Association encourage transferring intracerebral hemorrhage patients from community hospitals to centers with stroke expertise. However, research on the differences in outcomes between transferred intracerebral hemorrhage hospitalizations and directly admitted hospitalizations have been largely limited to small single-center studies. In this study, we explored the national trends in transferred intracerebral hemorrhage hospitalizations, as well as evaluated the differences, in terms of demographic characteristics, co-morbidity, resource utilization, and outcomes, between transferred intracerebral hemorrhage hospitalizations and directly admitted hospitalizations.

MATERIALS AND METHODS

From the National Inpatient Sample (2004 - 2016), we assessed the linear trends in the proportion of interhospital transfers for intracerebral hemorrhage hospitalizations. We constructed a series of multivariate logistic regression models to explore the association of transfer status with inpatient mortality and discharge disposition, controlling for demographic, clinical, and hospital characteristics. We used survey design variables to report nationally weighted estimates.

RESULTS

Among 786,999 hospitalizations, 137,340 (17.5%, 95% CI: 16.4-18.6) were transferred. Overall, interhospital transfers for intracerebral hemorrhage has been increasing over the 12-year period of this study. Patients in transferred hospitalizations were younger, more likely to be white, and more likely to have private insurance. Transferred hospitalizations were associated with significantly lower adjusted odds of inpatient mortality, compared to directly admitted hospitalizations.

CONCLUSIONS

As the US healthcare system continues shifting towards value-based care, evidence on the short- and long-term outcomes of transfer of intracerebral hemorrhage patients will inform optimal management of intracerebral hemorrhage patients.

Evaluation of the safety of inter-hospital transfers of critically ill patients led by advanced critical care practitioners

INTRODUCTION

Ten thousand inter-hospital transfers of critically ill adults take place annually in the UK. Studies highlight deficiencies in experience and training of staff, equipment, stabilisation before departure, and logistical difficulties. This article is a quality improvement review of an advanced critical care practitioner (ACCP)-led inter-hospital transfer service.

METHODS

The tool Standards for Quality Improvement Reporting Excellence was used as the format for the review, combined with clinical audit of advanced critical care practitioner-led transfers over a period of more than 3 years.

RESULTS

The transfer service has operated for 8 years; ACCPs conducted 934 critical care transfers of mechanically ventilated patients, including 286 inter-hospital transfers, between January 2017 and September 2020. The acuity of transfer patients was high, 82.2% required support of more than one organ, 49% required more than 50% oxygen. Uneventful transfer occurred in 81.4% of cases; the most common patient-related complication being hypotension, logistical issues were responsible for half of the complications.

CONCLUSION

This quality improvement project provides an example of safe and effective advanced practice in an area that is traditionally a medically led domain. ACCPs can provide an alternative process of care for critically ill adults who require external transfer, and a benchmark for audit and quality improvement.

Interhospital Transfer of Patients With Acute Pulmonary Embolism (PE): Challenges and Opportunities

Acute pulmonary embolism (PE) is associated with significant morbidity and mortality. The management paradigm for acute PE has evolved in recent years with wider availability of advanced treatment modalities ranging from catheter-directed reperfusion therapies to mechanical circulatory support. This evolution has coincided with the development and implementation of institutional pulmonary embolism response teams (PERT) nationwide and internationally. Because most institutions are not equipped or staffed for advanced PE care, patients often require transfer to centers with more comprehensive resources, including PERT expertise. One of the unmet needs in current PE care is an organized approach to the process of interhospital transfer (IHT) of critically ill PE patients. In this review, we discuss medical optimization and support of patients before and during transfer, transfer checklists, defined roles of emergency medical services, and the roles and responsibilities of referring and receiving centers involved in the IHT of acute PE patients.

Soft Factors, Smooth Transport? The role of safety climate and team processes in reducing adverse events during intrahospital transport in intensive care

BACKGROUND

Intrahospital patient transports (IHTs) in intensive care involve an appreciable risk of adverse events (AEs). Research on determinants of AE occurrence during IHT has hitherto focused on patient, transport, and intensive care unit (ICU) characteristics. By contrast, the role of "soft" factors, although arguably relevant for IHTs and a topic of interest in general health care settings, has not yet been explored.

PURPOSE

The study aims at examining the effect of safety climate and team processes on the occurrence of AE during IHT and whether team processes mediate the effect of safety climate.

METHODOLOGY/APPROACH

Data stem from a noninterventional, observational multicenter study in 33 ICUs (from 12 European countries), with 858 transports overall recorded during 28 days. AEs include medication errors, dislodgments, equipment failures, and delays. Safety climate scales were taken from the "Patient Safety Climate in Healthcare Organizations" (short version), team processes scales from the "Leiden Operating Theatre and Intensive Care Safety" questionnaire. Patient condition was assessed with NEMS (Nine Equivalents of Nursing Manpower Use Score). All other variables could be directly observed. Hypothesis testing and assessment of effects rely on bivariate correlations and binomial logistic multilevel models (with ICU as random effect).

FINDINGS

Both safety climate and team processes are comparatively important determinants of AE occurrence, also when controlling for transport-, staff-, and ICU-related variables. Team processes partially mediate the effect of safety climate. Patient condition and transport duration are consistently related with AE occurrence, too.

PRACTICE IMPLICATIONS

Unlike most patient, transport, and ICU characteristics, safety climate and team processes are basically amenable to managerial interventions. Coupled with their considerable effect on AE occurrence, this makes pertinent endeavors a potentially promising approach for improving patient safety during IHT. Although literature suggests that safety climate is slow and hard to change (also compared to team processes), efforts to improve safety climate should not be forgone.

Adverse events experienced with intrahospital transfer of critically ill patients: A national survey

ABSTRACT

Research that focuses on transfers to and from the intensive care unit (ICU) could highlight important patients' safety issues. This study aims to describe healthcare workers' (HCWs) practices involved in patient transfers to or from the ICU.This cross-sectional study was conducted among HCWs during the Saudi Critical Care Society's annual International Conference, April 2017. Responses were assessed using Likert scales and frequencies. Bivariate analysis was used to evaluate the significance of different indicators.Overall, 312 HCWs participated in this study. Regarding transfer to ICUs, the most frequently reported complications were deterioration in respiratory status (51.4%), followed by deterioration in hemodynamic status (46.5%), and missing clinical information (35.5%). Regarding transfers from ICUs to the general ward, the most commonly reported complications were changes in respiratory status (55.6%), followed by incomplete clinical information (37.9%), and change in hemodynamic conditions (29%). The most-used models for communicating transfers were written documents in electronic health records (69.3%) and verbal communication (62.8%). One-fourth of the respondents were not aware of the Situation, Background, Assessment, Recommendation (SBAR) method of patients' handover. Pearson's test of correlation showed that the HCW's perceived satisfaction with their hospital transfer guidelines showed significant negative correlation with their reported transfer-related complications (r = -0.27, P < .010).Hemodynamic and respiratory status deterioration is representing significant adverse events among patients transferred to or from the ICU. Factors controlling the perceived satisfaction of HCWs involved in patients, transfer to and from the ICU need to be addressed, focusing on their compliance to the hospital-wide transfer and handover policies. Quality improvement initiatives could improve patient safety to transfer patients to and from the ICU and minimize the associated adverse events.

Methods and measures to quantify ICU patient heterogeneity

Patients in intensive care units are heterogeneous and the daily prediction of their days to discharge (DTD) a complex task that practitioners and computers are not always able to solve satisfactorily. In order to make more precise DTD predictors, it is necessary to have tools for the analysis of the heterogeneity of the patients. Unfortunately, the number of publications in this field is almost non-existent. In order to alleviate this lack of tools, we propose four methods and their corresponding measures to quantify the heterogeneity of intensive patients in the process of determining the DTD. These new methods and measures have been tested with patients admitted over four years to a tertiary hospital in Spain. The results deepen the understanding of the intensive patient and can serve as a basis for the construction of better DTD predictors.

Caring for critically ill patients during interhospital transfers: A qualitative study

BACKGROUND

The coronavirus pandemic has resulted in an increased number of interhospital transfers of patients with artificial airways. The transfer of these patients is associated with risks and has been experienced as highly challenging, which needs to be further explored.

AIMS AND OBJECTIVES

To describe critical care nurses' experiences of caring for critically ill patients with artificial airways during interhospital transfers.

DESIGN

A cross-sectional study using a qualitative approach was conducted during spring 2020. Participants were critical care nurses (n = 7) from different hospitals (n = 2).

METHODS

The data were collected through semi-structured interviews based on an interview guide. A qualitative content analysis using an inductive approach was performed.

RESULTS

The analysis resulted in one main theme, "Preserving the safety in an unknown environment," and three sub-themes, "Being adequately prepared is essential to feel secure," "Feeling abandoned and overwhelmingly responsible," and "Being challenged in an unfamiliar and risky environment."

CONCLUSIONS

Critical care nurses experienced interhospital transfers of critically ill patients with artificial airways as complex and risky. It is essential to have an overall plan in order to prevent any unpredictable and acute events. Adequate communication and good teamwork are key to the safe transfer of a critically ill patient in that potential complications and dangers to the patient can be prevented.

RELEVANCE TO CLINICAL PRACTICE

Standardized checklists need to be created to guide the transfers of critically ill patients with different conditions. This would prevent failures based on human or system factors, such as lack of experience and lack of good teamwork.

Impact of Prepatching on Paramedic In-Hospital Times for Emergent Interfacility Transfers

Background: The care required for patients at times necessitates they be transferred to another hospital capable of providing specialized care, a process known as an interfacility transfer. Delays to appropriate care for critically ill patients are associated with increased morbidity and mortality. Improving efficiencies in interfacility transport process can thus expedite the time to critical treatment. Traditionally paramedics would patch to a transport medicine physician (TMP) after initial patient contact to discuss the case and expected management during transport. The concept of prepatch shifts this discussion between the TMP and paramedics prior to initial patient contact. The objective of this study was to assess if prepatching with paramedics prior to arrival at the patient reduced the in-hospital time for emergent interfacility transfers transported by a provincial critical care transport organization. Methods: This was a retrospective cohort study of all emergent, adult interfacility transports for patients transported by a provincial critical care transport organization in Ontario, Canada from January 2016 to December 2019. Quantile regression was used to evaluate the impact of prepatching as well as patient and paramedic characteristics on paramedic in-hospital time. Results: A total of 10,088 patients were included in the study, with 3,606 patients having a prepatch conducted and 6,482 without. Ventilated patients and vasopressor use were associated with higher prepatch rates; with the use of prepatch in these patients increasing over subsequent years of the study. Additionally, patients requiring higher levels of care, including being mechanically ventilated or dependent on vasopressors, were associated with longer in-hospital times. Prepatching reduced in-hospital time by 4 minutes at the 90^th quantile across all patients. Conclusion: Prepatching reduced paramedic in-hospital time for emergent interfacility transports. Although the clinical impact of this reduction in time is uncertain, prepatching may serve in facilitating shared mental modeling between paramedics and TMPs which may be beneficial to patient safety and team performance.

Calcium Channel Blocker Intoxication: A Critical Care Transport Perspective

Calcium channel blockers (CCBs) have seen an increase in rate of non-therapeutic exposure that is both accidental and intentional in nature. Patients experiencing the toxic effects of a CCB overdose are resource intensive and can quickly outstrip the capabilities of local health systems, necessitating transfer to larger tertiary or quaternary care centers. We present a case of intentional non-dihydropyridine CCB overdose and toxicity in a 20-year-old patient requiring initial stabilization at a referring critical access emergency department with continuation of treatment and support during a 60-minute rotor wing transport from the referring hospital to an academic quaternary care center. Emphasis is placed on the unique challenges in resuscitation and ongoing critical care administration during the transport phase of care. Proper stabilization of patients, planning, and consideration of potential problems associated with transport can help minimize stresses and risk of the transport, improving the outcome of extremely ill patients even under challenging circumstances.

Measuring More than Mortality: A scoping review of air ambulance outcome measures in a combined Institutes of Medicine and Donabedian quality framework

INTRODUCTION

Measuring the performance of air ambulance services are complex and dynamic due to the variability and interconnectedness of emergency systems. The aim of this study is to review the range and nature of air ambulance outcome measures published in peer review articles and construct a quality framework based on the results. A scoping review of the literature was conducted to identify outcome measures that evaluate the quality of air ambulance services. Combined frameworks from the Institutes of Medicine (IOM) and Dr. Avedia Donabedian were used to create a dashboard structure for a framework of air ambulance outcome measures.

METHODS

A literature search strategy was undertaken, following PRISMA-ScR guidelines and included eight databases over the period 2001-2019. Qualitative content analysis was conducted in 4-phases: 1) table summary of selected article outcome measures, 2) content analysis themes, codes of outcome measures and independent variables 3) narrative description of main themes 4) visual dashboard diagram of service priorities and quality strategies, based on the findings.

RESULTS

Thirty-four articles were screened by full text and eighteen met the selection criteria. Twenty codes emerged and were grouped to form eight consistent outcome themes; asset/ team type, access to definitive interventions, prehospital factors, mortality, morbidity, responsiveness of service, accessibility of service and patient disposition.

CONCLUSIONS

A quality framework consisting of eight outcome measures was created, it also identified seven gaps which ordinarily require performance evaluation; patient comfort and satisfaction reporting, cultural awareness training, safety alarms in place to identify volume stress, optimal coordination of resources, cost of service analysis, comprehensive patient journey time and an adaptive referral system analysis. The measures in the framework provide a broad perspective of air ambulance performance we believe will help decision-making and planning to improve patients experience and outcomes.

Simulation study on flow rate accuracy of infusion pumps in vibration conditions during emergency patient transport

Infusion pumps are frequently used when transferring critically ill patients via patient transport cart, ambulance, or helicopter. However, the performance of various infusion pumps under these circumstances has not been explored. The aim of this study was to evaluate the flow rate accuracy of infusion pumps under various clinical vibration conditions. Experiments were conducted with four different types of pumps, including two conventional syringe pumps (Injectomat MC Agilia, Fresenius Kabi and TE-331, Terumo), one conventional peristaltic pump (Volumed μVP7000; Arcomed), and one new cylinder pump (H-100, Meinntech). The flow rate was measured using an infusion pump analyzer on a stable table (0 m/s²) for 1 h with 1 ml/h and 5 ml/h. Experiments were repeated in mild vibration (2 m/s²) (representing vibration of patients in a moving stretcher or ambulance), and in moderate vibration (6 m/s²) (representing vibration in helicopter transport). Any accidental bolus occurrence in extreme vibration situations (20 m/s²) was also analyzed. Simulated vibrations were reproduced by a custom-made vibration table. In the resting state without vibration and in mild vibration conditions, all pumps maintained good performance. However, in moderate vibration, flow rates in syringe pumps increased beyond their known error ranges, while flow rates in peristaltic pumps remained stable. In extreme vibration, accidental fluid bolus occurred in syringe pumps but not in peristaltic pumps. The newly developed cylinder pump maintained stable performance and was unaffected by external vibration environments.

The role of the quick sequential organ failure assessment score (qSOFA) and modified early warning score (MEWS) in the pre-hospitalization prediction of sepsis prognosis

OBJECTIVE

Many biomarkers and scoring systems to make clinical predictions about the prognosis of sepsis have been investigated. In this study, we aimed to assess the use of the quick sequential organ failure assessment score (qSOFA) and modified early warning score (MEWS) scoring systems in emergency health care services for sepsis to predict intensive care hospitalization and 28-day mortality.

METHOD

Patients who arrived by ambulance at the Emergency Department (ED) of Dışkapı YıldırımBeyazıt Training and Research Hospital between January 2017 and December 2019, and who were diagnosed with sepsis and admitted to the hospital were included in the study. Demographic data and physiological parameters from 112 ambulance case delivery forms were recorded.QSOFA and MEWS scores were calculated from vital parameters.

RESULTS

Of the 266 patients diagnosed with sepsis, 50% (n = 133) were female, and the mean age was 74.8 ± 13. The difference between the rate of intensive care (ICU) hospitalization and mortality for patients with a high MEWS and qSOFA score and patients whose MEWS and qSOFA score were lower was found to be statistically significant (p < 0.05). Thus, the criteria for MEWS and qSOFA could determine ICU hospitalization and early mortality. Those with a high MEWS value had a mortality rate approximately 1.24 times higher than those with a low MEWS value (p < 0.001, 95% CI: 1.110-1.385), while those with a high qSOFA score had a mortality rate approximately 2.0 times higher than those with a low qSOFA score (p < 0.001, 95% CI: 1.446-2.693). Those with a high MEWS were 1.34 times more likely than hose with a lower MEWS to require ICU hospitalization (p < 0.001, 95% CI: 1.1773-1.5131), while patients with a high qSOFA score were 3.21 times more likely than those with a lower qSOFA score to require ICU care (p < 0.001, 95% CI: 2.2289-4.6093).

CONCLUSION

Although qSOFA and MEWS are clinical scores used to identify septic patients outside the critical care unit, we believe that patients already diagnosed with sepsis can be assessed with qSOFA and MEWS prior to hospitalization to predict intensive care hospitalization and mortality. qSOFA was found be more valuable than MEWS in determining the prognosis of pre-hospitalization sepsis.

International Survey on Extracorporeal Membrane Oxygenation Transport

Extracorporeal membrane oxygenation (ECMO) is a lifesaving therapy for severe respiratory and circulatory failure. It is best performed in high-volume centers to optimize resource utilization and outcomes. Regionalization of ECMO might require the implementation of therapy before and during transfer to the high-volume center. The aim of this international survey was to describe the manner in which interhospital ECMO transport care is organized at experienced centers. Fifteen mobile ECMO centers from nine countries participated in this survey. Seven (47%) of them operated under the "Hub-and-Spoke" model. Transport team composition varies from three to nine members, with at least one ECMO specialist (i.e., nurse or perfusionist) participating in all centers, although intensivists and surgeons were present in 69% and 50% of the teams, respectively. All centers responded that the final decision to initiate ECMO is multidisciplinary and made bedside at the referring hospital. Most centers (75%) have a quality control system; all teams practice simulation and water drills. Considering the variability in ECMO transport teams among experienced centers, continuous education, training and quality control within each organization itself are necessary to avoid adverse events and maintain a low mortality rate. A specific international ECMO Transport platform to share data, benchmark outcomes, promote standardization, and provide quality control is required.

Indian National Association for the Study of Liver Consensus Statement on Acute Liver Failure (Part-2): Management of Acute Liver Failure

Acute liver failure (ALF) is not an uncommon complication of a common disease such as acute hepatitis. Viral hepatitis followed by antituberculosis drug-induced hepatotoxicity are the commonest causes of ALF in India. Clinically, such patients present with appearance of jaundice, encephalopathy, and coagulopathy. Hepatic encephalopathy (HE) and cerebral edema are central and most important clinical event in the course of ALF, followed by superadded infections, and determine the outcome in these patients. The pathogenesis of encephalopathy and cerebral edema in ALF is unique and multifactorial. Ammonia plays a crucial role in the pathogenesis, and several therapies aim to correct this abnormality. The role of newer ammonia-lowering agents is still evolving. These patients are best managed at a tertiary care hospital with facility for liver transplantation (LT). Aggressive intensive medical management has been documented to salvage a substantial proportion of patients. In those with poor prognostic factors, LT is the only effective therapy that has been shown to improve survival. However, recognizing suitable patients with poor prognosis has remained a challenge. Close monitoring, early identification and treatment of complications, and couseling for transplant form the first-line approach to manage such patients. Recent research shows that use of dynamic prognostic models is better for selecting patients undergoing liver transplantation and timely transplant can save life of patients with ALF with poor prognostic factors.

Critical care nurses' lived experiences of interhospital intensive care unit-to-unit transfers: A phenomenological hermeneutical study

OBJECTIVE

To explore critical care nurses' lived experiences of transferring intensive care patients between hospitals.

METHODS

A phenomenological hermeneutic approach using data generated through individual interviews with 11 critical care registered nurses.

SETTING

Two general intensive care units in Sweden.

FINDINGS

Five themes were identified: it depends on me; your care makes a difference; being exposed; depending on interprofessional relationships; and sensing professional growth. These themes were synthesised into a comprehensive understanding showing how transferring intensive care patients between hospitals meant being on an ambivalent journey together with the patient but also on a journey within yourself in your own development and growth, where you, as a nurse, constantly are torn between contradictory feelings and experiences.

CONCLUSION

Interhospital intensive care unit-to-unit transfers can be a challenging task for critical care nurses but also an important opportunity for professional growth. During the transfer, nurses become responsible for the patient, their colleagues and the entire transfer process. In a time of an increasing number of interhospital intensive care unit-to-unit transfers, this study illuminates the risk for missed nursing care, showing that the critical care nurse has an important role in protecting the patient from harm and safeguarding dignified care.

Dealing with the Sick Rural Surgery Patient in Need of Transfer

Care for rural and urban surgical patients is increasingly more complex due to advancing knowledge and technology. Interhospital transfers occur in approximately 10% of index encounters at rural hospitals secondary to mismatch of patient needs and local resources. Due to the recent expansion of air transport to rural areas, distance and geography are less of a barrier. The interhospital transfer process is understudied and far from standardized. Interhospital transfer status is associated with increase in mortality, complications, length of stay, and costs. The cost, price to patients, and safety of air ambulance transports cannot be ignored.

Family members' lived experiences when a loved one undergoes an interhospital intensive care unit-to-unit transfer: A phenomenological hermeneutical study

AIMS AND OBJECTIVES

To reveal meanings of family members' lived experiences when a loved one undergoes an interhospital intensive care unit-to-unit transfer.

BACKGROUND

Interhospital intensive care unit-to-unit transfers take place between different hospitals and their respective intensive care units (ICUs). These types of transfers are an increasing phenomenon but are sparsely studied from the family members' perspective. Indeed, the patient's critical illness and care can have a major impact on family members. During the transfer process, there is a demand for the involved intensive care health personnel to make family members feel safe and cared for.

DESIGN

A qualitative design based on phenomenological hermeneutics.

METHODS

The study was conducted at two Swedish general ICUs. Data were generated through individual in-depth interviews with seven family members and analysed using a phenomenological hermeneutical approach. The Criteria for Reporting Qualitative Research principles were applied in the conduct and reporting of this study.

RESULTS

Four themes that reveal meanings of family members' lived experiences were developed: losing your safe haven, dealing with uncertainty, carrying your own and others' burdens and a wish to be close.

CONCLUSIONS

The study reveals that an interhospital intensive care unit-to-unit transfer affects the whole family and is characterised by family members experiencing many negative feelings. The findings also illustrate that being a family member when a loved one is transferred means being exposed to the core existential elements of being human, such as loneliness and searching for meaning.

RELEVANCE TO CLINICAL PRACTICE

The study highlights the importance of maintaining a family-centred approach during the transfer process. Our findings can provide deeper knowledge for intensive care health personnel, better preparing them for the delicate task of providing family-centred care during the interhospital intensive care unit-to-unit transfer process.

Incidents related to critical patient safety during in-hospital transfer

OBJECTIVE

To analyze the incidents related to patient safety (IRSP) and their risk factors during in-hospital transfer (IHT) of critical patients after the application of a protocol, and to evaluate safety during transfer using quality indicators.

DESIGN

A prospective, observational and non-intervention cohort study was carried out.

SETTING

A 10-bed multipurpose Intensive Care Unit (ICU) of a second level university hospital.

PATIENTS

All IHTs of critical patients in the ICU for diagnostic tests and to the operating room between March 2011 and March 2017 were included in the study.

MAIN MEASUREMENTS

Demographic variables, patient severity, transfer priority, moment of the day, reason and type of transfer team. Pre-transport checklist items and IRSP were collected. A biannual analysis was made of quality indicators designed for IHT.

RESULTS

A total of 805 transfers were registered, mostly of an urgent nature (53.7%) and for diagnostic tests (77%). In turn, 112 transfers (13.9%) presented some type of IRSP; 54% related to the equipment and 30% related to team and organization. Adverse events occurred in 19 (2.4%) transfers. Risk factors identified in the multivariate analysis were mechanical ventilation and the transport team. The evolution of the indicators related to transport was significantly favorable.

CONCLUSIONS

After the application of an IHT protocol, IRSP are low. The main risk factor is invasive mechanical ventilation. The experience of the team performing IHT influences the detection of a greater number of incidents.

[Influence of the blood gas composition and mechanical ventilation parameters of the medical evacuation prognosis of critically ill patients.]

The clinical estimation of the state of patient is one of the basic components of the checking of the state of patient, but more precise and more objective indices today become necessary. The arterial blood gases analysis helps to select the optimum regime of mechanical ventilation. The medical evacuation of the critically ill patients frequently requires the correction of the parameters of respiratory support. The conducted investigations showed that the prognostics of unfavorable outcome within the first three days from the moment of the medical evacuation are hypercapnia, which exists during the process of evacuation in spite of the correction of the parameters of mechanical ventilation, reduction in the saturation of the arterial blood. The forecast of the medical evacuation is located as well in the direct correlation with the manifestation of acidosis, and at the moment of the completion of the transfer of the patient the greatest prognostic significance they possess the low level of the partial tension of oxygen in the artery. The application of a portable express- analyzer of blood gases permits implementation of correction parameters of respiratory support and to increase quality and safety of the medical evacuation of patients.

Incidence and Risk Factors of Clinical Deterioration during Inter-Facility Transfer of Critically Ill Patients; a Cohort Study

INTRODUCTION

Critically ill and injured patients are at a higher risk of developing clinical deterioration during inter-facility transfers. This study aimed to determine the incidence rate and risk factors of clinical deterioration among critically ill patients during inter-facility transfers in Thailand.

METHODS

The present cohort study was conducted in 22 referring hospitals and 7 receiving hospitals under the supervision of Ministry of Public Health, Thailand, between March 15 and December 31, 2018. The subjects were comprised of 839 critically ill patients aged 18 and over, 63 coordinator nurses in referral centers, and 312 referral team leaders. Data collected included pre-transfer risk score, clinical data of patient during transfer, characteristics of referral team leader, ambulance type, preparation time, time to definitive care, transfer distance, and National Early Warning Score (NEWS) (clinical deterioration). Multilevel mixed-effects regression analysis was performed.

RESULTS

The incidence rate of clinical deterioration was 28.69%. The most common types of clinical deterioration were hemodynamic instability, respiratory instability, and neurological alteration. Time between 31-45 minutes was significantly associated with clinical deterioration (β 0.133, P value 0.027). The following illnesses were associated with higher probability of clinical deterioration: body region injuries/head injury/burn/ingested poison (β 0.670, P value 0.030), respiratory distress/convulsion (β 0.919, P value 0.001), shock/ arrhythmias/chest pain/hemorrhage (β 1.134, P value <0.001), comatose/alteration of consciousness/syncope (β 1.343, P value <0.001), and post-cardiac arrest (β 2.251, P value <0.001). Patients with unstable conditions (β 1.689, P value 0.001) and pre-transfer risk score of 8 or higher (β 0.625, P value 0.001) had a higher rate of deterioration. Transfer by non- emergency room (ER) nurses (β 0.495, P value 0.008) and transportation in a mobile intensive care unit (ICU) were associated with a higher rate of deterioration (β 0.848, P value 0.001).

CONCLUSION

The incidence of clinical deterioration during inter-facility transfer in Thailand was high. Illnesses involving circulatory, respiratory, and neurological systems, clinical instability, high pre-transfer risk score, transport time of 31-45 minutes, transportation by non-ER nurse, and mobile ICU were associated with a higher rate of clinical deterioration.

The pattern of neonatal admissions and mortality at a regional and district hospital in the Upper West Region of Ghana; a cross sectional study

BACKGROUND

High global neonatal deaths have triggered efforts to improve facility-based care. However, the outcomes achievable at different levels of care are unclear. This study compared morbidity and mortality patterns of newborns admitted to a regional and a district hospital in Ghana to determine outcome, risk and modifiable factors associated with mortality.

OBJECTIVE

This study compared morbidity and mortality patterns of newborns admitted to a regional and a district hospital in Ghana to determine outcome, risk and modifiable factors associated with mortality.

METHODS

A cross-sectional study involving a records-review over one year at the Upper West Regional Hospital, and three years at St Joseph's District Hospital, Jirapa was carried out. Age, sex, gestational age, weight, duration of admission, diagnosis, among others were examined. The data were analysed and statistical inference made.

RESULTS

Altogether, 2004 newborns were examined, comprising 1,241(62%) from St Joseph's District Hospital and 763(38%) from Upper West Regional Hospital. The proportion of neonatal deaths was similar, 8.94% (St Joseph's District Hospital) and 8.91% (Upper West Regional Hospital). Prematurity, neonatal sepsis, birth asphyxia, low birth weight, neonatal jaundice and pneumonia contributed the most to mortality and suspected infections including malaria accounted for almost half (45.5%). Mortality was significantly associated with duration of stay of 48 hours, being premature, and being younger than 3 days.

CONCLUSION

Majority of the mortality among the neonates admitted was due to preventable causes. Better stabilization and further studies on the epidemiology of sepsis, prematurity, low birth weight, including the contribution of malaria to these and outcome of transferred neonates are needed.

Assessment of interhospital transport care for pediatric patients

BACKGROUND

Many critically ill patients require transfer to a higher-level hospital for complex medical care. Despite the publication of the American Academy of Pediatrics guidelines for pediatric interhospital transportation services and the establishment of many pediatric transport programs, adverse events during pediatric transport still occur.

PURPOSE

To determine the incidence of adverse events occurring during pediatric transport and explore their complications and risk factors.

METHODS

This prospective observational study explored the adverse events that occurred during the interhospital transport of all pediatric patients referred to the pediatric intensive care unit of Ramathibodi Hospital between March 2016 and June 2017.

RESULTS

There were 122 pediatric transports to the unit. Adverse events occurred in 25 cases (22%). Physiologic deterioration occurred in 15 patients (60%). Most issues (11 events) involved circulatory problems causing patient hypotension and poor tissue perfusion requiring fluid resuscitation or inotropic administration on arrival at the unit. Respiratory complications were the second most common cause (4 events). Equipmentrelated adverse events occurred in 5 patients (20%). The common causes were accidental extubation and endotracheal tube displacement. Five patients had both physiologic deterioration and equipment-related adverse events. Regarding transport personnel, the group without complications more often had a physician escort than the group with complications (92% vs. 76%; relative risk, 2.4; P=0.028).

CONCLUSION

The incidence of adverse events occurring during the transport of critically ill pediatric patients was 22%. Most events involved physiological deterioration. Escort personnel maybe the key to preventing and appropriately monitoring complications occurring during transport.

Air ambulance outcome measures using Institutes of Medicine and Donabedian quality frameworks: protocol for a systematic scoping review

BACKGROUND

Dedicated air ambulance services provide a vital link for critically ill and injured patients to higher levels of care. The recent developments of pre-hospital and retrieval medicine create an opportunity for air ambulance providers and policy-makers to utilize a dashboard of quality performance measures to assess service performance. The objective of this scoping systematic review will be to identify and evaluate the range of air ambulance outcome measures reported in the literature and help to construct a quality dashboard based on a healthcare quality framework.

METHODS

We will search PubMed, MEDLINE, CINAHL, Scopus, and Cochrane Database of Systematic Reviews (from January 2001 onwards). Complementary searches will be conducted in selected relevant journals. We will include systematic reviews and observational studies (cohort, cross-sectional, interrupted time series) in critically ill or injured patients published in English and focusing on air ambulance delivery and quality measures. Two reviewers will independently screen all citations, full-text articles, and abstract data. The study methodological quality (or bias) will be appraised using appropriate tools. Analysis of the characteristics associated with outcome measure will be mapped and described according to the proposed healthcare quality framework.

DISCUSSION

This review will contribute to the development of an air ambulance quality dashboard designed to combine multiple quality frameworks. Our findings will provide a basis for helping decision-making in health planning and policy.

Safety of inter-hospital transfer of patients with acute ischemic stroke for evaluation of endovascular thrombectomy

Stroke networks facilitate access to endovascular treatment (EVT) for patients with ischemic stroke due to large vessel occlusion. In this study we aimed to determine the safety of inter-hospital transfer and included all patients with acute ischemic stroke who were transferred within our stroke network for evaluation of EVT between 06/2016 and 12/2018. Data were derived from our prospective EVT database and transfer protocols. We analyzed major complications and medical interventions associated with inter-hospital transfer. Among 615 transferred patients, 377 patients (61.3%) were transferred within our telestroke network and had transfer protocols available (median age 76 years [interquartile range, IQR 17], 190 [50.4%] male, median baseline NIHSS score 17 [IQR 8], 246 [65.3%] drip-and-ship i.v.-thrombolysis). No patient suffered from cardio-respiratory failure or required emergency intubation or cardiopulmonary resuscitation during the transfer. Among 343 patients who were not intubated prior departure, 35 patients (10.2%) required medical interventions during the transfer. The performance of medical interventions was associated with a lower EVT rate and higher mortality at three months. In conclusion, the transfer of acute stroke patients for evaluation of EVT was not associated with major complications and transfer-related medical interventions were required in a minority of patients.
