Experiences of parents visiting an adult family member in the intensive care unit accompanied by their underaged children: A qualitative study

OBJECTIVES

The objective of this study was to explore experiences and needs of parents visiting critically ill family members in intensive care units (ICUs) accompanied by their underaged children (<18 years).

METHODS

Six semistructured interviews with parents were conducted in a qualitative design. Data analysis and synthesis were performed using Braun and Clarke's thematic analysis. This study was conducted in five adult ICUs in Switzerland.

FINDINGS

Parents opted for early and truthful involvement of their children, and the majority initiated the visits themselves. Five themes were identified: feeling of shock by the entire family; crying in front of the children; feeling welcome with the children; knowing that the children can cope with it; and holding the family together. Parents felt only partially welcomed in the ICU when accompanied by their children. In one case, the parents withdrew the child from the visit.

CONCLUSIONS

Parents experienced the visit to a critically ill family member in the ICU with their underaged children as challenging. They were emotionally vulnerable and yet took the initiative to keep the family together. Parents had to mediate between their children, the critically ill family member, and the treatment team. Awareness of the needs of the parents visiting with underaged children is important in clinical practice. There is a need for family-centred structures and processes, including adequate visiting times and rooms suitable for children with books, pictures, and toys.

[Lessons from the COVID-19-Pandemic : Experiences of critical care nurses during the COVID-19 pandemic: a qualitative explorative study]

BACKGROUND

When the workload for critical care nurses becomes too high, this can have consequences for both personal health as well as patient care. During the COVID-19 pandemic, critical care nurses were confronted with new and dynamic changes.

OBJECTIVE

The aim of this study was to describe the experiences of critical care nurses regarding the ad hoc measures taken and the perceived physical and psychological burden experienced during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

This was a cross-sectional study conducted at two hospitals using an online survey. The open questions addressing the challenges faced during the COVID-19 pandemic were subjected to content analysis according to Mayring.

RESULTS

A total of 179 critical care nurses participated in the online survey. From the results, the following four categories were developed: "not meeting one's own quality of care requirements," "uncertainties in everyday professional and private life," "increased responsibility with lack of relief," and "insufficient coping strategies for physical and psychological burden."

CONCLUSION

Critical care nurses require structures and processes which support them in situations of high workload. The focus should be on the self-imposed requirements of quality of care as well as potentially relieving measures.

Effects of an online information tool on post-traumatic stress disorder in relatives of intensive care unit patients: a multicenter double-blind, randomized, placebo-controlled trial (ICU-Families-Study)

PURPOSE

Intensive care unit (ICU) hospitalization is challenging for the family members of the patients. Most family members report some level of anxiety and depression, sometimes even resulting in post-traumatic stress disorder (PTSD). An association has been reported between lack of information and PTSD. This study had three aims: to quantify the psychological burden of family members of critically ill patients, to explore whether a website with specific information could reduce PTSD symptoms, and to ascertain whether a website with information about intensive care would be used.

METHOD

A multicenter double-blind, randomized, placebo-controlled trial was carried out in Austria and Switzerland.

RESULTS

In total, 89 members of families of critically ill patients (mean age 47.3 ± 12.9 years, female n = 59, 66.3%) were included in the study. 46 relatives were allocated to the intervention website and 43 to the control website. Baseline Impact of Event Scale (IES) score was 27.5 ± 12.7. Overall, 50% showed clinically relevant PTSD symptoms at baseline. Mean IES score for the primary endpoint (~ 30 days after inclusion, T1) was 24 ± 15.8 (intervention 23.9 ± 17.9 vs. control 24.1 ± 13.5, p = 0.892). Hospital Anxiety and Depression Scale (HADS - Deutsch (D)) score at T1 was 12.2 ± 6.1 (min. 3, max. 31) and did not differ between groups. Use of the website differed between the groups (intervention min. 1, max. 14 vs. min. 1, max. 3; total 1386 "clicks" on the website, intervention 1021 vs. control 365). Recruitment was prematurely stopped in February 2020 due to coronavirus disease 2019 (COVID-19).

CONCLUSION

Family members of critically ill patients often have significant PTSD symptoms and online information on critical illness did not result in reduced PTSD symptoms.

Effects of immersive virtual reality on sensory overload in a random sample of critically ill patients

Background

Sensory overload and sensory deprivation have both been associated with negative health outcomes in critically ill patients. While there is a lack of any clear treatment or prevention strategies, immersive virtual reality is a promising tool for addressing such problems, but which has not been repetitively tested in random samples. Therefore, this study aimed to determine how critically ill patients react to repeated sessions of immersive virtual reality.

Methods

This exploratory study was conducted in the mixed medical-surgical intermediate care unit of the University Hospital of Bern (Inselspital). Participants (N = 45; 20 women, 25 men; age = 57.73 ± 15.92 years) received two immersive virtual reality sessions via a head-mounted display and noise-canceling headphones within 24 h during their stay in the unit. Each session lasted 30-min and showed a 360-degree nature landscape. Physiological data were collected as part of the participants' standard care, while environmental awareness, cybersickness, and general acceptance were assessed using a questionnaire designed by our team (1 = not at all, 10 = extremely).

Results

During both virtual reality sessions, there was a significant negative linear relationship found between the heart rate and stimulation duration [first session: r(43) = -0.78, p < 0.001; second session: r(38) = -0.81, p < 0.001] and between the blood pressure and stimulation duration [first session: r(39) = -0.78, p < 0.001; second session: r(30) = -0.78, p < 0.001]. The participants had a high comfort score [median (interquartile range {IQR}) = 8 (7, 10); mean = 8.06 ± 2.31], did not report being unwell [median (IQR) = 1 (1, 1); mean = 1.11 ± 0.62], and were not aware of their real-world surroundings [median (IQR) = 1 (1, 5); mean = 2.99 ± 3.22].

Conclusion

The subjectively reported decrease in environmental awareness as well as the decrease in the heart rate and blood pressure over time highlights the ability of immersive virtual reality to help critically ill patients overcome sensory overload and sensory deprivation. Immersive virtual reality can successfully and repetitively be provided to a randomly selected sample of critically ill patients over a prolonged duration.

Creating Custom Immersive 360-Degree Videos for Use in Clinical and Nonclinical Settings: Tutorial

The use of virtual reality (VR) stimulation in clinical settings has increased in recent years. In particular, there has been increasing interest in the use of VR stimulation for a variety of purposes, including medical training, pain therapy, and relaxation. Unfortunately, there is still a limited amount of real-world 360-degree content that is both available and suitable for these applications. Therefore, this tutorial paper describes a pipeline for the creation of custom VR content. It covers the planning and designing of content; the selection of appropriate equipment; the creation and processing of footage; and the deployment, visualization, and evaluation of the VR experience. This paper aims to provide a set of guidelines, based on first-hand experience, that readers can use to help create their own 360-degree videos. By discussing and elaborating upon the challenges associated with making 360-degree content, this tutorial can help researchers and health care professionals anticipate and avoid common pitfalls during their own content creation process.

Guideline on multimodal rehabilitation for patients with post-intensive care syndrome

BACKGROUND

Intensive Care Unit (ICU) survivors often experience several impairments in their physical, cognitive, and psychological health status, which are labeled as post-intensive care syndrome (PICS). The aim of this work is to develop a multidisciplinary and -professional guideline for the rehabilitative therapy of PICS.

METHODS

A multidisciplinary/-professional task force of 15 healthcare professionals applied a structured, evidence-based approach to address 10 scientific questions. For each PICO-question (Population, Intervention, Comparison, and Outcome), best available evidence was identified. Recommendations were rated as "strong recommendation", "recommendation" or "therapy option", based on Grading of Recommendations, Assessment, Development and Evaluation principles. In addition, evidence gaps were identified.

RESULTS

The evidence resulted in 12 recommendations, 4 therapy options, and one statement for the prevention or treatment of PICS.

RECOMMENDATIONS

early mobilization, motor training, and nutrition/dysphagia management should be performed. Delirium prophylaxis focuses on behavioral interventions. ICU diaries can prevent/treat psychological health issues like anxiety and post-traumatic stress disorders. Early rehabilitation approaches as well as long-term access to specialized rehabilitation centers are recommended. Therapy options include additional physical rehabilitation interventions. Statement: A prerequisite for the treatment of PICS are the regular and repeated assessments of the physical, cognitive and psychological health in patients at risk for or having PICS.

CONCLUSIONS

PICS is a variable and complex syndrome that requires an individual multidisciplinary, and multiprofessional approach. Rehabilitation of PICS should include an assessment and therapy of motor-, cognitive-, and psychological health impairments.

Characterization of sound pressure levels and sound sources in the intensive care unit: a 1 week observational study

Background

Exposure to elevated sound pressure levels within the intensive care unit is known to negatively affect patient and staff health. In the past, interventions to address this problem have been unsuccessful as there is no conclusive evidence on the severity of each sound source and their role on the overall sound pressure levels. Therefore, the goal of the study was to perform a continuous 1 week recording to characterize the sound pressure levels and identify negative sound sources in this setting.

Methods

In this prospective, systematic, and quantitative observational study, the sound pressure levels and sound sources were continuously recorded in a mixed medical-surgical intensive care unit over 1 week. Measurements were conducted using four sound level meters and a human observer present in the room noting all sound sources arising from two beds.

Results

The mean 8 h sound pressure level was significantly higher during the day (52.01 ± 1.75 dBA) and evening (50.92 ± 1.66 dBA) shifts than during the night shift (47.57 ± 2.23; F(2, 19) = 11.80, p < 0.001). No significant difference was found in the maximum and minimum mean 8 h sound pressure levels between the work shifts. However, there was a significant difference between the two beds in the based on location during the day (F(3, 28) = 3.91, p = 0.0189) and evening (F(3, 24) = 5.66, p = 0.00445) shifts. Cleaning of the patient area, admission and discharge activities, and renal interventions (e.g., dialysis) contributed the most to the overall sound pressure levels, with staff talking occurring most frequently.

Conclusion

Our study was able to identify that continuous maintenance of the patient area, patient admission and discharge, and renal interventions were responsible for the greatest contribution to the sound pressure levels. Moreover, while staff talking was not found to significantly contribute to the sound pressure levels, it was found to be the most frequently occurring activity which may indirectly influence patient wellbeing. Overall, identifying these sound sources can have a meaningful impact on patients and staff by identifying targets for future interventions, thus leading to a healthier environment.

Developing a reflection and analysis tool (We-ReAlyse) for readmissions to the intensive care unit: A quality improvement project

BACKGROUND

Readmissions to the intensive care unit are associated with poorer patient outcomes and health prognoses, alongside increased lengths of stay and mortality risk. To improve quality of care and patients' safety, it is essential to understand influencing factors relevant to specific patient populations and settings. A standardized tool for systematic retrospective analysis of readmissions would help healthcare professionals understand risks and reasons affecting readmissions; however, no such tool exists.

PURPOSE

This study's purpose was to develop a tool (We-ReAlyse) to analyze readmissions to the intensive care unit from general units by reflecting on affected patients' pathways from intensive care discharge to readmission. The results will highlight case-specific causes of readmission and potential areas for departmental- and institutional-level improvements.

METHOD

A root cause analysis approach guided this quality improvement project. The tool's iterative development process included a literature search, a clinical expert panel, and a testing in January and February 2021.

RESULTS

The We-ReAlyse tool guides healthcare professionals to identify areas for quality improvement by reflecting the patient's pathway from the initial intensive care stay to readmission. Ten readmissions were analyzed by using the We-ReAlyse tool, resulting in key insights about possible root causes like the handover process, patient's care needs, the resources on the general unit and the use of different electronic healthcare record systems.

CONCLUSIONS

The We-ReAlyse tool provides a visualization/objectification of issues related to intensive care readmissions, gathering data upon which to base quality improvement interventions. Based on the information on how multi-level risk profiles and knowledge deficits contribute to readmission rates, nurses can target specific quality improvements to reduce those rates.

IMPLICATIONS FOR CLINICAL PRACTICE AND RESEARCH

With the We-ReAlyse tool, we have the opportunity to collect detailed information about ICU readmissions for an in-depth analysis. This will allow health professionals in all involved departments to discuss and either correct or cope with the identified issues. In the long term, this will allow continuous, concerted efforts to reduce and prevent ICU readmissions. To obtain more data for analysis and to further refine and simplify the tool, it may be applied to larger samples of ICU readmissions. Furthermore, to test its generalizability, the tool should be applied to patients from other departments and other hospitals. Adapting it to an electronic version would facilitate the timely and comprehensive collection of necessary information. Finally, the tool's emphasis comprises reflecting on and analyzing ICU readmissions, allowing clinicians to develop interventions targeting the identified problems. Therefore, future research in this area will require the development and evaluation of potential interventions.

[Children visiting intensive care units and emergency departments : Kids are welcome!]

In this white paper, key recommendations for visitation by children in intensive care units (ICU; both pediatric and adult), intermediate care units and emergency departments (ED) are presented. In ICUs and EDs in German-speaking countries, the visiting policies for children and adolescents are regulated very heterogeneously: sometimes they are allowed to visit patients without restrictions in age and time duration, sometimes this is only possible from the age of teenager on, and only for a short duration. A request from children to visit often triggers different, sometimes restrictive reactions among the staff. Management is encouraged to reflect on this attitude together with their employees and to develop a culture of family-centered care. Despite limited evidence, there are more advantages for than against a visit, also in hygienic, psychosocial, ethical, religious, and cultural aspects. No general recommendation can be made for or against visits. The decisions for a visit are complex and require careful consideration.

Perceived sounds and their reported level of disturbance in intensive care units: A multinational survey among healthcare professionals

PURPOSE

The noise levels in intensive care units have been repeatedly reported to exceed the recommended guidelines and yield negative health outcomes among healthcare professionals. However, it is unclear which sound sources within this environment are perceived as disturbing. Therefore, this study aimed to evaluate how healthcare professionals in Germany, Switzerland, and Austria perceive the sound levels and the associated sound sources within their work environment and explore sound reduction strategies.

MATERIAL AND METHODS

An online survey was conducted among 350 healthcare professionals working in intensive care units. The survey consisted of items on demographic and hospital data and questions about the perception of the sound levels [1 (strongly disagree) to 5 (strongly agree)], disturbance from sound sources [1 (not disturbing at all) to 5 (very disturbing)], and implementation potential, feasibility, and motivation to reduce sound reduction measures [1 (not high at all) to 5 (very high)].

RESULTS

Approximately 69.3% of the healthcare professionals perceived the sound levels in the ICUs as too high. Short-lasting human sounds (e.g. moans or laughs) [mean (M) ± standard deviation (SD) = 3.30 ± 0.81], devices and alarms (M ± SD = 2.67 ± 0.59), and short-lasting object sounds (M ± SD = 2.55 ± 0.68) were perceived as the most disturbing sounds. Reducing medical equipment alarms was considered to have greater implementation potential [M ± SD = 3.62 ± 0.92, t(334) = -7.30, p < 0.001], feasibility [M ± SD = 3.19 ± 0.93, t(334) = -11.02, p < 0.001], and motivation [M ± SD = 3.85 ± 0.89, t(334) = -10.10, p < 0.001] for reducing the sound levels.

CONCLUSION

This study showed that healthcare professionals perceive short-lasting human sounds as most disturbing and rated reducing medical equipment alarms as the best approach to reduce the sound levels in terms of potential, feasibility, and motivation for implementation.

Dynamics of disease characteristics and clinical management of critically ill COVID-19 patients over the time course of the pandemic: an analysis of the prospective, international, multicentre RISC-19-ICU registry

Background

It remains elusive how the characteristics, the course of disease, the clinical management and the outcomes of critically ill COVID-19 patients admitted to intensive care units (ICU) worldwide have changed over the course of the pandemic.

Methods

Prospective, observational registry constituted by 90 ICUs across 22 countries worldwide including patients with a laboratory-confirmed, critical presentation of COVID-19 requiring advanced organ support. Hierarchical, generalized linear mixed-effect models accounting for hospital and country variability were employed to analyse the continuous evolution of the studied variables over the pandemic.

Results

Four thousand forty-one patients were included from March 2020 to September 2021. Over this period, the age of the admitted patients (62 [95% CI 60–63] years vs 64 [62–66] years, p < 0.001) and the severity of organ dysfunction at ICU admission decreased (Sequential Organ Failure Assessment 8.2 [7.6–9.0] vs 5.8 [5.3–6.4], p < 0.001) and increased, while more female patients (26 [23–29]% vs 41 [35–48]%, p < 0.001) were admitted. The time span between symptom onset and hospitalization as well as ICU admission became longer later in the pandemic (6.7 [6.2–7.2| days vs 9.7 [8.9–10.5] days, p < 0.001). The PaO₂/FiO₂ at admission was lower (132 [123–141] mmHg vs 101 [91–113] mmHg, p < 0.001) but showed faster improvements over the initial 5 days of ICU stay in late 2021 compared to early 2020 (34 [20–48] mmHg vs 70 [41–100] mmHg, p = 0.05). The number of patients treated with steroids and tocilizumab increased, while the use of therapeutic anticoagulation presented an inverse U-shaped behaviour over the course of the pandemic. The proportion of patients treated with high-flow oxygen (5 [4–7]% vs 20 [14–29], p < 0.001) and non-invasive mechanical ventilation (14 [11–18]% vs 24 [17–33]%, p < 0.001) throughout the pandemic increased concomitant to a decrease in invasive mechanical ventilation (82 [76–86]% vs 74 [64–82]%, p < 0.001). The ICU mortality (23 [19–26]% vs 17 [12–25]%, p < 0.001) and length of stay (14 [13–16] days vs 11 [10–13] days, p < 0.001) decreased over 19 months of the pandemic.

Conclusion

Characteristics and disease course of critically ill COVID-19 patients have continuously evolved, concomitant to the clinical management, throughout the pandemic leading to a younger, less severely ill ICU population with distinctly different clinical, pulmonary and inflammatory presentations than at the onset of the pandemic.

Early Rehabilitation Interventions and Physical Therapy in Adults Who Were Critically Ill with COVID−19 Pneumonia: A Retrospective Observational Study

Objective

The primary objective of this observational study was to analyze the time to the first edge-of-bed (EOB) mobilization in adults who were critically ill with severe versus non-severe COVID-19 pneumonia. Secondary objectives included the description of early rehabilitation interventions and physical therapy delivery.

Methods

All adults with laboratory-confirmed COVID-19 requiring intensive care unit admission for ≥72 hours were included and divided according to their lowest PaO2/FiO2 ratio into severe (≤ 100 mmHg) or non-severe (&gt; 100 mmHg) COVID-19 pneumonia. Early rehabilitation interventions consisted of in-bed activities, edge-of-bed or out-of-bed mobilizations, standing, and walking. The Kaplan–Meier estimate and logistic regression were used to investigate the primary outcome time-to-EOB and factors associated with delayed mobilization.

Results

Among the 168 patients included in the study (mean age = 63 y [SD = 12 y]; Sequential Organ Failure Assessment [SOFA] = 11 [IQR 9–14]), 77 (46%) were classified as non-severe and 91 (54%) were classified as severe COVID-19 pneumonia. Median time-to-EOB was 3.9 days (95% CI = 2.3–5.5) with significant differences between subgroups (non-severe = 2.5 days [95% CI = 1.8–3.5]; severe = 7.2 days [95% CI = 5.7–8.8]). Extracorporeal membrane oxygenation (ECMO) use and high SOFA scores (adjusted effect = 13.7 days [95% CI = 10.1–17.4] and 0.3 days [95% CI = 0.1–0.6]) were significantly associated with delayed EOB mobilization. Physical therapy started within a median of 1.0 days (95% CI = 0.9–1.2) without subgroup differences.

Conclusions

This study shows that early rehabilitation and physical therapy within the recommended 72 hours during the COVID-19 pandemic could be maintained regardless of disease severity. In this cohort, the median time-to-EOB was fewer than 4 days, with disease severity and advanced organ support significantly delaying the time-to-EOB.

Impact

Early rehabilitation in the intensive care unit could be sustained in adults who are critically ill with COVID-19 pneumonia and can be implemented with existing protocols. Screening based on PaO2/FiO2 ratio might reveal patients at risk and increased need for physical therapy.

Video calls did not reduce PTSD symptoms in relatives during restricted ICU visits in the COVID-19 pandemic

To help reduce the spread of the SARS-CoV-2 virus during the COVID-19 pandemic, ICU visits were banned or restricted. Therefore, family-centered care as usually practiced was not feasible Video calls were recommended to meet relatives’ needs. The aim of this study was to investigate the effect of video calls on symptoms of post-traumatic stress disorder (PTSD) in relatives of ICU patients. This single-center study was performed during the first wave (15.03.2020‒30.04.2020; visits banned) and the second wave (01.10.20‒08.02.21: visits restricted) of the COVID-19 pandemic. The Impact of Event Scale-Revised (IES-R) was used to assess PTSD symptoms and an adapted version of the Family Satisfaction in the Intensive Care Unit 24-Item-Revised questionnaire (aFS-ICU 24R) to assess family satisfaction 3 months after ICU stay. The primary outcome was the difference in IES-R score at 3 months between the video call group (VCG) and the standard care group (SCG, no video calls). In addition, inductive content analysis of relatives’ comments regarding their satisfaction with decision-making and ICU care was performed. Fifty-two relatives (VCG: n = 26, SCG: n = 26) were included in this study. No significant difference in IES-R scores was observed between the VCG and the SCG (49.52 ± 13.41 vs. 47.46 ± 10.43, p = 0.54). During the ICU stay (mean 12 days, range 5.25‒18.75 days), the members of the VCG made a median of 3 (IQR 1‒10.75) video calls. No difference between the groups was found for conventional telephone calls during the same period (VCG: 9 calls, IQR 3.75‒18.1; SCG: 5 calls, IQR 3‒9; p = 0.12). The aFS-ICU 24R scores were high for both groups: 38 (IQR 37‒40) in the VCG and 40 (IQR 37‒40: p = 0.24) in the SCG. Video calls appeared largely ineffective in reducing PTSD symptoms or improving satisfaction among relatives affected by banning/restriction of ICU visits during the COVID-19 pandemic. Further investigations are needed to acquire more data on the factors involved in PTSD symptoms experienced by relatives of ICU patients during the COVID-19 pandemic.

Visual and auditory stimulation for patients in the intensive care unit: A mixed-method study

OBJECTIVES

To determine what type (e.g., television, photographs, music, etc), content (e.g., nature scenes, family members, etc), and duration of visual and auditory stimuli should be provided to intensive care unit patients during their hospitalisation.

RESEARCH METHODOLOGY AND DESIGN

This mixed-methods study followed an exploratory-descriptive design. In total, 31 participants were interviewed: 19 were former critically ill patients in the intensive care unit and 12 were nursing experts, all from a university hospital in Switzerland. Based on current practice, patients and nurses were familiar with receiving and providing television, photographs, radio, and musical stimuli, with no specific exposure to virtual reality, aside from that in their personal lives. Data were collected from the former patients using structured interviews, whereas semi-structured interviews were used for the nursing experts.

FINDINGS

Overall, patient and expert opinions aligned well; both groups agreed that receiving visual and/or auditory stimuli would benefit patients. Photographs, television, and virtual reality were the visual stimuli most chosen by the patients, with an emphasis on nature-focused content. When appropriate, audio matching the content should be provided alongside the visual stimuli to act as a distraction from the hospital environment. Visual stimuli should not exceed 10-15 min, while auditory stimuli should not exceed one hour.

CONCLUSION

Sensory overload and deprivation are common problems in the intensive care unit with negative effects on patient outcomes. Based on patient and expert opinions, visual and auditory stimuli are desired by patients and could help address these issues.

A multicomponent family support intervention in intensive care units: study protocol for a multicenter cluster-randomized trial (FICUS Trial)

Background

Family members of critically ill patients face considerable uncertainty and distress during their close others’ intensive care unit (ICU) stay. About 20–60% of family members experience adverse mental health outcomes post-ICU, such as symptoms of anxiety, depression, and posttraumatic stress. Guidelines recommend structured family inclusion, communication, and support, but the existing evidence base around protocolized family support interventions is modest and requires substantiation.

Methods

To test the clinical effectiveness and explore the implementation of a multicomponent, nurse-led family support intervention in ICUs, we will undertake a parallel, cluster-randomized, controlled, multicenter superiority hybrid-type 1 trial. It will include eight clusters (ICUs) per study arm, with a projected total sample size of 896 family members of adult, critically ill patients treated in the German-speaking part of Switzerland. The trial targets family members of critically ill patients with an expected ICU stay of 48 h or longer. Families in the intervention arm will receive a family support intervention in addition to usual care. The intervention consists of specialist nurse support that is mapped to the patient pathway with follow-up care and includes psycho-educational and relationship-focused family interventions, and structured, interprofessional communication, and shared decision-making with families. Families in the control arm will receive usual care. The primary study endpoint is quality of family care, operationalized as family members’ satisfaction with ICU care at discharge. Secondary endpoints include quality of communication and nurse support, family management of critical illness (functioning, resilience), and family members’ mental health (well-being, psychological distress) measured at admission, discharge, and after 3, 6, and 12 months. Data of all participants, regardless of protocol adherence, will be analyzed using linear mixed-effects models, with the individual participant as the unit of inference.

Discussion

This trial will examine the effectiveness of the family support intervention and generate knowledge of its implementability. Both types of evidence are necessary to determine whether the intervention works as intended in clinical practice and could be scaled up to other ICUs. The study findings will make a significant contribution to the current body of knowledge on effective ICU care that promotes family participation and well-being.

Methods for Measuring and Identifying Sounds in the Intensive Care Unit

Background

Despite many studies in the field examining excessive noise in the intensive care unit, this issue remains an ongoing problem. A limiting factor in the progress of the field is the inability to draw conclusions across studies due to the different and poorly reported approaches used. Therefore, the first goal is to present a method for the general measurement of sound pressure levels and sound sources, with precise details and reasoning, such that future studies can use these procedures as a guideline. The two procedures used in the general method will outline how to record sound pressure levels and sound sources, using sound level meters and observers, respectively. The second goal is to present the data collected using the applied method to show the feasibility of the general method and provide results for future reference.

Methods

The general method proposes the use of two different procedures for measuring sound pressure levels and sound sources in the intensive care unit. The applied method uses the general method to collect data recorded over 24-h, examining two beds in a four-bed room, via four sound level meters and four observers each working one at a time.

Results

The interrater reliability of the different categories was found to have an estimate of >0.75 representing good and excellent estimates, for 19 and 16 of the 24 categories, for the two beds examined. The equivalent sound pressure levels (L_Aeq) for the day, evening, and night shift, as an average of the sound level meters in the patient room, were 54.12, 53.37, and 49.05 dBA. In the 24-h measurement period, talking and human generated sounds occurred for a total of 495 (39.29% of the time) and 470 min (37.30% of the time), at the two beds of interest, respectively.

Conclusion

A general method was described detailing two independent procedures for measuring sound pressure levels and sound sources in the ICU. In a continuous data recording over 24 h, the feasibility of the proposed general method was confirmed. Moreover, good and excellent interrater reliability was achieved in most categories, making them suitable for future studies.

Practice of family-centred care in intensive care units before the COVID-19-pandemic: A cross-sectional analysis in German-speaking countries

OBJECTIVES

To provide insights into visiting policies and family-centred care practices with a focus on children as visitors in Intensive Care Units in German-speaking countries.

METHODS/DESIGN

Online-survey with a mixed methods approach. Leading clinicians (n = 1943) from German-speaking countries were invited to participate. Outcomes included the percentage of intensive care units with open visiting policies, age restrictions, family-centred care activities and barriers.

SETTING

Paediatric, mixed and adult units RESULTS: In total, 19.8% (n = 385) of the clinicians responded. Open visiting times were reported by 36.3% (n = 117), with significant differences between paediatric (79.2%), adult (21.3%) and mixed-age (41.2%) units (p < 0.01). Two-thirds of clinicians stated that their units had no age restrictions for children as visitors (n = 221, 68.4%). The family-centred care activities most frequently implemented were open visiting times and dissemination of information. Significantly more German units have open visiting policies and more Swiss units allow children as visitors, compared to the other countries (both p < 0.001). Barriers to family-centred care were concerns about children being traumatized, infection and workload.

CONCLUSION

The majority reported that family-centred care policies had been implemented in their units, including open visiting policies, allowing children as visitors without age restriction and other family-centred care activities.

Influence of noise manipulation on retention in a simulated ICU ward round: an experimental pilot study

Background

Noise exposure leads to a reduction in cognitive abilities in diverse settings, however, only limited data exist examining the effects of environmental ICU noise on the cognitive performance of ICU professionals. A frequently occurring and demanding retention task in ICUs are ward rounds, which are considered key for the provision of medical care. Here, we investigate the influence of noise on information retention in a simulated ward round.

Methods

ICU professionals were exposed to a recorded, ICU ward round, simulated partly with and partly without environmental ICU noise. Ward rounds were followed by specific questions about previously provided information.

Results

56 ICU professionals (aged 26–59 years) were included. A logistic mixed model showed a reduction of 27% (P < 0.001) in the ward round test performance when participants were exposed to environmental ICU noise. Furthermore, advanced age was associated with reduced retention (− 28%, P < 0.001), questions containing important information performed better (+ 36%, P < 0.001), and higher stress led to better performance in retention (+ 24%, P = 0.01).

Conclusions

Our data showed a considerable negative influence of environmental ICU noise during a simulated ward round. Therefore, reduction of environmental ICU noise is recommended. The influence of additional factors, including stress, priorities, and demographic factors should be pursued in subsequent investigations.

Insights into the challenges faced by chronically critically ill patients, their families and healthcare providers: An interpretive description

OBJECTIVE

To describe and understand the challenges of patients with chronic critical illness (CCI), their families and healthcare providers during the disease trajectory.

METHODOLOGY/DESIGN

This qualitative study follows Thorne's methodology of interpretive description and was guided by the ethnographic method of observation and participation. Five cases, each comprising one patient with chronic critical illness their family members and several healthcare providers, were followed from the intensive care unit of a university hospital in Switzerland across different settings. In total, five patients with chronic critical illness, 12 family members and 92 healthcare providers (nurses, nursing students, care assistants, physiotherapists and occupational therapists and physicians) were observed.

FINDINGS

Regardless of the medical diagnoses and disease trajectories of the patients with chronic critical illness, all cases faced three main challenges: 1. Dealing with the unpredictability of the disease trajectory beyond the underlying disease. 2. Coping with the complexity of care. 3. Perceiving communication challenges despite all involved parties' dependency on it.

CONCLUSION

Unpredictability is not only a unique characteristic of the prolonged disease trajectory of patients with chronic critical illness, but also one of the main challenges of the participants. Therefore, the way unpredictability is handled is dependent on changes in the complexity of care and communication, highlighting the need for participation, information, empathy, clarity and honesty among all participants.

Symptoms of post-traumatic stress disorder (PTSD) in next of kin during suspension of ICU visits during the COVID-19 pandemic: a prospective observational study

BACKGROUND

During the COVID-19 pandemic, suspension of visits by next of kin to patients in intensive care units (ICU), to prevent spread of the SARS-CoV-2 virus, has been a common practice. This could impede established family-centered care and may affect the mental health of the next of kin. The aim of this study was to explore symptoms of post-traumatic stress syndrome (PTSD) in the next of kin of ICU patients.

METHODS

In this prospective observational single-center study, next of kin of ICU patients were interviewed by telephone, using the Impact of Event Scale-Revised (IES-R), to assess symptoms of acute stress disorder during the ICU stay and PTSD symptoms at 3 months after the ICU stay. The primary outcome was the prevalence of severe PTSD symptoms (IES-R score ≥ 33) at 3 months. The secondary outcomes comprised the IES-R scores during the ICU stay, at 3 months, and the prevalence of severe symptoms of acute stress disorder during ICU stay. An inductive content analysis was performed of the next of kin's comments regarding satisfaction with patient care and the information they were given.

RESULTS

Of the 411 ICU patients admitted during the study period, 62 patients were included together with their next of kin. An IES-R score > 33 was observed in 90.3% (56/62) of next of kin during the ICU stay and in 69.4% (43/62) 3 months later. The median IES-R score was 49 (IQR 40-61) during the ICU stay and 41 (IQR 30-55) at 3 months. The inductive content analysis showed that communication/information (55%), support (40%), distressing emotions (32%), and suspension of ICU visits (24%) were mentioned as relevant aspects by the next of kin.

CONCLUSIONS

During the suspension of ICU visits in the COVID-19 pandemic, high prevalence and severity of both symptoms of acute stress disorder during the ICU stay and PTSD symptoms 3 months later were observed in the next of kin of ICU patients.

Near real-time observation reveals increased prevalence of young patients in the ICU during the emerging third SARS-CoV-2 wave in Switzerland

AIMS OF THE STUDY

During the ongoing COVID-19 pandemic, the launch of a large-scale vaccination campaign and virus mutations have hinted at possible changes in transmissibility and the virulence affecting disease progression up to critical illness, and carry potential for future vaccination failure. To monitor disease development over time with respect to critically ill COVID-19 patients, we report near real-time prospective observational data from the RISC-19-ICU registry that indicate changed characteristics of critically ill patients admitted to Swiss intensive care units (ICUs) at the onset of a third pandemic wave.

METHODS

1829 of 3344 critically ill COVID-19 patients enrolled in the international RISC-19-ICU registry as of 31 May 2021 were treated in Switzerland and were included in the present study. Of these, 1690 patients were admitted to the ICU before 1 February 2021 and were compared with 139 patients admitted during the emerging third pandemic wave RESULTS: Third wave patients were a mean of 5.2 years (95% confidence interval [CI] 3.2&ndash;7.1) younger (median 66.0 years, interquartile range [IQR] 57.0&ndash;73.0 vs 62.0 years, IQR 54.5&ndash;68.0; p &lt;0.0001) and had a higher body mass index than patients admitted in the previous pandemic period. They presented with lower SAPS II and APACHE II scores, less need for circulatory support and lower white blood cell counts at ICU admission. P/F ratio was similar, but a 14% increase in ventilatory ratio was observed over time (p = 0.03) CONCLUSION: Near real-time registry data show that the latest COVID-19 patients admitted to ICUs in Switzerland at the onset of the third wave were on average 5 years younger, had a higher body mass index, and presented with lower physiological risk scores but a trend towards more severe lung failure. These differences may primarily be related to the ongoing nationwide vaccination campaign, but the possibility that changes in virus-host interactions may be a co-factor in the age shift and change in disease characteristics is cause for concern, and should be taken into account in the public health and vaccination strategy during the ongoing pandemic.

Importance of critical care staffing and standard intensive care therapy in the COVID-19 era: a descriptive study of the first epidemic wave at a Swiss tertiary intensive care unit

AIM

Mortality rates of COVID-19 patients hospitalised in intensive care units (ICUs) are generally high. Availability of ICU resources might influence clinical outcomes. The aim of this study was to examine the clinical course of the 42 patients treated during the first epidemic wave between 2 March and 20 May 2020 at the tertiary ICU of the Bern University Hospital, where staffing, equipment and drugs were not limited.

METHODS

For this descriptive study, retrospective data of the first COVID-19 wave in an interdisciplinary adult ICU of a Swiss University hospital was used. The study included data regarding healthcare staffing and COVID-19 patients. The primary outcome was the ICU mortality in COVID-19 patients.

RESULTS

Patients&rsquo; median age was 61 years (range 32&ndash;86), simplified acute physiology score (SAPS-II) was 46 (13&ndash;90), 81% of the patients were males, 79% were mechanically ventilated (3 of them on extracorporeal membrane oxygenation), 31% were under renal replacement therapy and 21% received steroids. All patients were fully anticoagulated from the time of admission. No off-label experimental antiviral or anti-inflammatory drugs were used with the exception of one patient, and antibiotic prescription was restrictive. Nurse-to-patient ratio was 1:1 during all shifts, and the physician-to-patient ratio was 1:4 (day shift) and 1:10 (night shift). Infectious disease specialists and physiotherapists were present every day. The median ICU length of stay was 10 days (1&ndash;38) days, and ICU and hospital mortality rates were 7% and 12%, respectively.

CONCLUSION

Careful intensive care treatment, without off-label drug use but including steroids in selected cases, combined with an interdisciplinary approach and provision of sufficient human resources, were associated with low ICU and hospital mortality rates despite high disease severity. Availability of qualified human resources may have an important impact on the outcome of COVID-19.

Virtual reality stimulation to reduce the incidence of delirium in critically ill patients: study protocol for a randomized clinical trial

BACKGROUND

Delirium has been long considered as a major contributor to cognitive impairments and increased mortality following a critical illness. Pharmacologic and non-pharmacologic strategies are used against delirium in the intensive care unit (ICU), despite these strategies remaining controversial. Previous studies have shown the feasibility of using virtual reality within the ICU setting, and we propose to use this technology to investigate the effect of immersive virtual reality stimulation on the incidence of delirium in the ICU. Moreover, we propose to use motion sensors to determine if patient movement patterns can lead to early prediction of delirium onset.

METHODS

This study is conducted as a randomized clinical trial. A total of 920 critically ill patients in the ICU will participate. The control group will receive standard ICU care, whereas the intervention group will, in addition to the standard ICU care, receive relaxing 360-degree immersive virtual reality content played inside a head-mounted display with noise-cancelling headphones, three times a day. The first 100 patients, regardless of their group, will additionally have their movement patterns recorded using wearable and ambient sensors. Follow-up measurements will take place 6 months after discharge from the ICU.

DISCUSSION

Delirium is widely present within the ICU setting but lacks validated prevention and treatment strategies. By providing patients with virtual reality stimulation presented inside a head-mounted display and noise-cancelling headphones, participants may be isolated from disturbances on an ICU. It is believed that by doing so, the incidence of delirium will be decrease among these patients. Moreover, identifying movement patterns associated with delirium would allow for early detection and intervention, which may further improve long-term negative outcomes associated with delirium during critical care.

In sechs Wochen hat sich die Welt verändert: COVID-19

In six weeks the world has changed: COVID-19 - Family-centered care in the intensive care unit Abstract. Background and problem definition: The admission of patients to an intensive care unit is extremely stressful for relatives during the COVID-19 pandemic, as they are not allowed to visit their family members due to a visitation restriction.

OBJECTIVES

To describe the experience of relatives during the COVID-19 pandemic and to derive support information for health professionals.

METHODS

Qualitative analysis of three written testimonies of relatives whose family members were hospitalized with COVID-19 or other disease at intensive care unit.

RESULTS

Relatives report the sudden, unexpected occurrence of the disease. "It was there, out of nowhere, hits the heart of life, doesn't just go away, does what it wants. It is an unknown virus that we have to get to know very closely." The ban on visiting was harsh, it made her faint. The first visit was an indescribable joy. Knowing how the family member was and that the health care professionals were taking professional and empathetic care of the sick person were the only things the relatives could hold on to.

DISCUSSION

Relatives were reassured when they experienced a high level of commitment on the part of health professionals and received repeated comprehensible information by phone. Limitations and transfer: Restrictions on visits depend on national legislation. Measures such as video calls can also be useful outside of a pandemic to build relationships with relatives.

Risks in Management of Enteral Nutrition in Intensive Care Units: A Literature Review and Narrative Synthesis

Critically ill patients in the intensive care unit (ICU) have a high risk of developing malnutrition, and this is associated with poorer clinical outcomes. In clinical practice, nutrition, including enteral nutrition (EN), is often not prioritized. Resulting from this, risks and safety issues for patients and healthcare professionals can emerge. The aim of this literature review, inspired by the Rapid Review Guidebook by Dobbins, 2017, was to identify risks and safety issues for patient safety in the management of EN in critically ill patients in the ICU. Three databases were used to identify studies between 2009 and 2020. We assessed 3495 studies for eligibility and included 62 in our narrative synthesis. Several risks and problems were identified: No use of clinical assessment or screening nutrition assessment, inadequate tube management, missing energy target, missing a nutritionist, bad hygiene and handling, wrong time management and speed, nutritional interruptions, wrong body position, gastrointestinal complication and infections, missing or not using guidelines, understaffing, and lack of education. Raising awareness of these risks is a central aspect in patient safety in ICU. Clinical experts can use a checklist with 12 identified top risks and the recommendations drawn up to carry out their own risk analysis in clinical practice.

Zwischen Himmel und Hölle: Erfahrungen von Eltern mit einem kritisch kranken Kind mit extrakorporaler Membranoxygenierung (ECMO) - Eine qualitative-explorative Studie mit Paarinterviews

Between Heaven and Hell: Experiences of parents with a critically ill child with extracorporeal membrane oxygenation (ECMO) - A qualitative-explorative study with couple interviews Abstract. Background: It is a traumatic experience for parents when their child's severe illness necessitates a period of intensive care. This situation becomes even more challenging for parents if a highly technical therapy such as extracorporeal membrane oxygenation (ECMO) in the Pediatric Intensive Care Unit is required. Aim: The study explores the experiences of parents of critically ill children undergoing ECMO therapy with the aim of better understanding their needs and identifying courses of action for healthcare professionals. Method: The qualitative-explorative study was based on interviews with six couples whose critically ill child is or has been receiving ECMO during the last year, which were used to examine their experiences. The analysis of six such interviews was performed using intensive paraphrasing and inductive coding. Results: The parents' situation can be best characterised as ambivalent with simultaneous feelings of hope and fear. They recognize the danger to their child's life, leading to intense feelings of helplessness with strong emotional reactions. It becomes apparent that there is too little fit between the emotional world of the parents and the action patterns of the health care professionals. Conclusions: The health care professionals thinking logic is based on professional criteria, such as the life threat and risks of ECMO, which ignores the emotional needs of the parents. For this reason, it is important to be more sensitive to the parents and to share positive little signs about their child' s state of health and ability to suffer with them.

Effects of intensive care unit ambient sounds on healthcare professionals: results of an online survey and noise exposure in an experimental setting

BACKGROUND

Noise levels on intensive care units (ICUs) are typically elevated. While many studies reported negative effects of ICU ambient sounds on patients, only few investigated noise as a factor to influence well-being or performance in healthcare professionals.

METHODS

An online survey in the German-speaking part of Switzerland was conducted to assess how ICU soundscapes are subjectively perceived by healthcare professionals. The questionnaire was answered by 348 participants. Additionally, effects of noise on working memory performance were evaluated in an experimental noise exposure setting. Twenty-six healthcare professionals and 27 healthy controls performed a 2-back object-location task while being exposed to either ICU or pink noise.

RESULTS

Survey results demonstrate that a majority of participants was aware of heightened noise levels. Participants reported that mostly well-being, performance, and attention could be reduced, along with subjective annoyance and fatigue by ICU ambient sounds. Although no significant effects of noise exposure on working memory performance was observed, self-assessments revealed significantly higher stress levels, increased annoyance and distraction ratings as well as decreased confidence in performance after ICU-noise exposure.

CONCLUSION

Subjective assessments indicate that heightened noise levels on ICUs induce annoyance, with heightened stress levels, impaired well-being, and reduced performance being potential consequences. Empirical evidence with objective and physiological measures is warranted.

Perception and Performance on a Virtual Reality Cognitive Stimulation for Use in the Intensive Care Unit: A Non-randomized Trial in Critically Ill Patients

Background: Newly acquired long-term cognitive impairments are common among survivors of critical illness. They have been linked to the stressful situation that patients experience in the intensive care unit (ICU). In this paper we use virtual reality (VR) technology to comfort critically ill patients and reduce stress during their ICU stay. We investigate the acceptance, comfort, recollection, and visual perception of VR stimulation and how it affects physiological parameters.

Methods: A VR head-mounted display was used to present immersive nature scenes to 33 critically ill cardiac surgery patients [mean age 63 years (range 32–83)]. Data was collected with an eye tracker fitted inside the VR head-mounted display to measure eye movements (250 Hz) and sensors to record physiological parameters (240 Hz). Patients received VR stimulation (for 5 min.) prior to ICU admission, during ICU stay, and 3 months after discharge. Acceptance, recollection and comfort were assessed with validated questionnaires.

Results: The number of gazed meaningful objects per minute was significantly lower during the ICU session compared to pre- and follow-up sessions, whereas mean duration of fixation on meaningful moving objects did not differ between the sessions. While respiratory rate decreased significantly during VR stimulation, heart rate and blood pressure remained constant. Post-ICU rating of VR acceptance during ICU stay was moderate to high and discomfort low. Recollection of VR was high [28/33 patients (84.8%)], while recollection of ICU stay was low [10/33 patients (30.3%)].

Conclusion: Eye movements indicate that patients were able to perceive and process cognitive stimulation during their ICU stay. VR was recalled better than the rest of the ICU stay and well accepted. Decreased respiratory rate during stimulation indicate a relaxing effect of VR.

Comparing the Relaxing Effects of Different Virtual Reality Environments in the Intensive Care Unit: Observational Study

Background

After a prolonged intensive care unit (ICU) stay, approximately 50%-75% of all critically ill patients suffer from neurocognitive late effects and a reduction of health-related quality of life. It is assumed that the noisy and stressful ICU environment leads to sensory overload and deprivation and potentially to long-term cognitive impairment.

Objective

In this study, we investigated three different virtual reality environments and their potentially restorative and relaxing effects for reducing sensory overload and deprivation in the ICU.

Methods

A total of 45 healthy subjects were exposed to three different environments, each 10 minutes in length (dynamic, virtual, natural, and urban environments presented inside the head-mounted display, and a neutral video on an ICU TV screen). During the study, data was collected by validated questionnaires (ie, restoration and sickness) and sensors to record physiological parameters (240 hertz).

Results

The results showed that the natural environment had the highest positive and restorative effect on the physiological and psychological state of healthy subjects, followed by the urban environment and the ICU TV screen.

Conclusions

Overall, virtual reality stimulation with head-mounted display using a dynamic, virtual and natural environment has the potential, if directly used in the ICU, to reduce sensory overload and deprivation in critically ill patients and thus to prevent neurocognitive late effects.

[Anxiety during the chronic critical illness in the intensive care unit - an interpretive phenomenological study]

Anxiety during the chronic critical illness in the intensive care unit - an interpretive phenomenological study Abstract.

BACKGROUND

Patients with a chronic critical illness (CCI) are persons who are dependent on life-sustaining therapies in the intensive care unit (ICU) for an extended period of time following a life-threatening, acute illness. In the ICU they are exposed to numerous physical and psychological stressors. Anxiety, one of the distressing symptoms, has received little attention.

AIM

This study aims to examine anxiety in adult patients who have developed CCI while treated in an ICU to further understand this phenomenon.

METHOD

An interpretive phenomenological approach was taken. Using an iterative process, data from guided interviews with seven participants were analysed.

RESULTS

The anxiety experienced by the patients with CCI fluctuated with the level of consciousness: anxiety in another reality, anxiety caused by nightmares, anxiety at first awakening and anxiety during wakeful periods. Anxiety was often accompanied by feelings of powerlessness, being lost, insecurity, helplessness and uncertainty.

CONCLUSIONS

The results of the study suggest that health care professionals caring for patients, especially nurses, may influence anxiety experienced by patients with CCI. Nurses who are able to recognize anxiety in patients with CCI have a better chance of caring for them in a sensitive manner.

Trigger Tool-Based Automated Adverse Event Detection in Electronic Health Records: Systematic Review

BACKGROUND

Adverse events in health care entail substantial burdens to health care systems, institutions, and patients. Retrospective trigger tools are often manually applied to detect AEs, although automated approaches using electronic health records may offer real-time adverse event detection, allowing timely corrective interventions.

OBJECTIVE

The aim of this systematic review was to describe current study methods and challenges regarding the use of automatic trigger tool-based adverse event detection methods in electronic health records. In addition, we aimed to appraise the applied studies' designs and to synthesize estimates of adverse event prevalence and diagnostic test accuracy of automatic detection methods using manual trigger tool as a reference standard.

METHODS

PubMed, EMBASE, CINAHL, and the Cochrane Library were queried. We included observational studies, applying trigger tools in acute care settings, and excluded studies using nonhospital and outpatient settings. Eligible articles were divided into diagnostic test accuracy studies and prevalence studies. We derived the study prevalence and estimates for the positive predictive value. We assessed bias risks and applicability concerns using Quality Assessment tool for Diagnostic Accuracy Studies-2 (QUADAS-2) for diagnostic test accuracy studies and an in-house developed tool for prevalence studies.

RESULTS

A total of 11 studies met all criteria: 2 concerned diagnostic test accuracy and 9 prevalence. We judged several studies to be at high bias risks for their automated detection method, definition of outcomes, and type of statistical analyses. Across all the 11 studies, adverse event prevalence ranged from 0% to 17.9%, with a median of 0.8%. The positive predictive value of all triggers to detect adverse events ranged from 0% to 100% across studies, with a median of 40%. Some triggers had wide ranging positive predictive value values: (1) in 6 studies, hypoglycemia had a positive predictive value ranging from 15.8% to 60%; (2) in 5 studies, naloxone had a positive predictive value ranging from 20% to 91%; (3) in 4 studies, flumazenil had a positive predictive value ranging from 38.9% to 83.3%; and (4) in 4 studies, protamine had a positive predictive value ranging from 0% to 60%. We were unable to determine the adverse event prevalence, positive predictive value, preventability, and severity in 40.4%, 10.5%, 71.1%, and 68.4% of the studies, respectively. These studies did not report the overall number of records analyzed, triggers, or adverse events; or the studies did not conduct the analysis.

CONCLUSIONS

We observed broad interstudy variation in reported adverse event prevalence and positive predictive value. The lack of sufficiently described methods led to difficulties regarding interpretation. To improve quality, we see the need for a set of recommendations to endorse optimal use of research designs and adequate reporting of future adverse event detection studies.

Changes in health-related quality of life in older patients one year after an intensive care unit stay

AIMS AND OBJECTIVES

This study investigates health-related quality of life in older patients, over one year following an intensive care unit stay.

BACKGROUND

Health-related quality of life is an important outcome when assessing long-term effectiveness of intensive care treatment, and to assist patients, their relatives and healthcare professionals in making treatment decisions.

DESIGN

Prospective non-randomised longitudinal study.

METHODS

The Short Form Health Survey 36 was administered 1 week after an intensive care stay (retrospective baseline), and after six months and 12 months to the study population and to an age-matched comparison group at recruitment (baseline), and after six months and 12 months. Demographic data, admission diagnosis, length of stay, severity of illness, pain, anxiety, agitation, and intratracheal suctioning, turning and intubation were recorded. Recruitment period: December 2008 to April 2011.

RESULTS

Health-related quality of life of the older patients was significantly lower than the comparison group, both before and after the intensive care unit stay, and showed great individual variability. Within group scores, however, were stable over the year. Both physical and mental health scores were lower for the older patients. Renal failure, cardiac surgery and illness severity were associated with lower physical health scores. Cardiovascular illness, intratracheal suctioning and turning were associated with lower mental health scores.

CONCLUSIONS

Health-related quality of life was lower in older patients than in the age-matched group but remained stable over one year.

RELEVANCE TO CLINICAL PRACTICE

Older patients with severe illnesses, acute renal failure or who have had cardiac surgery, need additional support after hospital discharge due to functional restrictions. Discharge planning should ensure that this support would be provided. Special attention should be given to develop and use methods to reduce distress during routine intensive care interventions such as intratracheal suctioning or turning.

Long-term consequences of pain, anxiety and agitation for critically ill older patients after an intensive care unit stay

AIMS AND OBJECTIVES

This study investigated whether an intensive care unit (ICU) stay is associated with persistent pain, anxiety and agitation in critically ill older patients.

BACKGROUND

Patients hospitalised in the ICU are at risk for experiencing pain, anxiety and agitation, but long-term consequences for older patients have rarely been investigated.

DESIGN

Prospective nonrandomised longitudinal study.

METHODS

Pain, anxiety and agitation, measured with a numeric rating scale (0-10), were assessed in older patients (≥65 years) hospitalised in the medical-surgical ICU of a university hospital. Agitation during the ICU was assessed with the Richmond Agitation-Sedation Scale. Data collection occurred during the ICU, one week after the stay and six and 12 months after hospital discharge. Data were collected from an age-matched community-based comparison group at recruitment and after six and 12 months. Study recruitment took place from December 2008-April 2011.

RESULTS

This study included 145 older patients (ICU group) and 146 comparison group participants. Pain was higher in the ICU group one week after discharge, although pain levels in general were low. Both groups reported no or low levels of pain after six and 12 months. Anxiety levels in general were low, although higher in the ICU group one week after ICU discharge. After six and 12 months, anxiety in both groups was comparable. Throughout the study, levels of agitation were similar in both groups.

CONCLUSIONS

Critically ill older patients did not experience increased pain, anxiety or agitation 12 months after an ICU stay.

RELEVANCE TO CLINICAL PRACTICE

This study positively shows that an ICU stay is not associated with persistent pain, anxiety and agitation thus providing additional information to older patients and their families when making intensive care treatment decisions. Adequate management of pain during and after an ICU stay may minimise the suffering of older patients.

Healthcare resource utilisation by critically ill older patients following an intensive care unit stay

AIMS AND OBJECTIVES

This study examines the utilisation of healthcare resources by critically ill older patients over one year following an intensive care unit stay.

BACKGROUND

Information on healthcare resource utilisation following intensive care unit treatment is essential during times of limited financial resources.

DESIGN

Prospective longitudinal nonrandomised study.

METHODS

Healthcare resource utilisation by critically ill older patients (≥65 years) was recorded during one year following treatment in a medical-surgical intensive care unit. Age-matched community-based participants served as comparison group. Data were collected at one-week following intensive care unit discharge/study recruitment and after 6 and 12 months. Recorded were length of stay, (re)admission to hospital or intensive care unit, general practitioner and medical specialist visits, rehabilitation program participation, medication use, discharge destination, home health care service use and level of dependence for activities of daily living.

RESULTS

One hundred and forty-five critically ill older patients and 146 age-matched participants were recruited into the study. Overall, critically ill older patients utilised more healthcare resources. After 6 and 12 months, they visited general practitioners six times more frequently, twice as many older patients took medications and only the intensive care unit group patients participated in rehabilitation programs (n = 99, 76%). The older patients were less likely to be hospitalised, very few transferred to nursing homes (n = 3, 2%), and only 7 (6%) continued to use home healthcare services 12 months following the intensive care unit stay.

CONCLUSIONS

Critically ill older patients utilise more healthcare resources following an intensive care unit stay, however, most are able to live at home with no or minimal assistance after one year.

RELEVANCE TO CLINICAL PRACTICE

Adequate healthcare resources, such as facilitated access to medical follow-up care, rehabilitation programs and home healthcare services, must be easily accessible for older patients following hospital discharge. Nurses need to be aware of the healthcare services available and advise patients accordingly.

Long-term consequences of an intensive care unit stay in older critically ill patients: design of a longitudinal study

BACKGROUND

Modern methods in intensive care medicine often enable the survival of older critically ill patients. The short-term outcomes for patients treated in intensive care units (ICUs), such as survival to hospital discharge, are well documented. However, relatively little is known about subsequent long-term outcomes. Pain, anxiety and agitation are important stress factors for many critically ill patients. There are very few studies concerned with pain, anxiety and agitation and the consequences in older critically ill patients. The overall aim of this study is to identify how an ICU stay influences an older person's experiences later in life. More specific, this study has the following objectives: (1) to explore the relationship between pain, anxiety and agitation during ICU stays and experiences of the same symptoms in later life; and (2) to explore the associations between pain, anxiety and agitation experienced during ICU stays and their effect on subsequent health-related quality of life, use of the health care system (readmissions, doctor visits, rehabilitation, medication use), living situation, and survival after discharge and at 6 and 12 months of follow-up.

METHODS/DESIGN

A prospective, longitudinal study will be used for this study. A total of 150 older critically ill patients in the ICU will participate (ICU group). Pain, anxiety, agitation, morbidity, mortality, use of the health care system, and health-related quality of life will be measured at 3 intervals after a baseline assessment. Baseline measurements will be taken 48 hours after ICU admission and one week thereafter. Follow-up measurements will take place 6 months and 12 months after discharge from the ICU. To be able to interpret trends in scores on outcome variables in the ICU group, a comparison group of 150 participants, matched by age and gender, recruited from the Swiss population, will be interviewed at the same intervals as the ICU group.

DISCUSSION

Little research has focused on long term consequences after ICU admission in older critically ill patients. The present study is specifically focussing on long term consequences of stress factors experienced during ICU admission.

[Identification of pain in the case of patients under sedation and artificial ventilation: A systematic literature review]

In intensive care units (ICU), patients in life-threatening situations are hospitalized. While the health status of these patients is often severely compromised, therapeutic interventions include endo-tracheal intubation with artificial ventilation, sedation, and analgesia which restrict their ability to communicate. These patients become additional vulnerable since their pains may not been adequately identified. Uncontrolled pain in sedated and artificial ventilated patients lead to increased number of respiration days and increased length of stay in hospital, which, may result in increased morbidity. This situation appears precarious since pain assessment of these patients in daily clinical practice seems often based on subjective criteria by the health care staff in charge. The purpose of this study was to describe pain-assessment instruments for sedated and artificial ventilated ICU-patients in view of validity, reliability and clinical application. With a systematic literature review, a total of 61 articles were identified in the databases of PUB-MED (National Library of Medicine) and CINAHL (Cumulative Index to Nursing and Allied Health Literature ) and additional bibliographic sources. Indicators for pain in sedated and artificial ventilated ICU-patients were physiological and behavior-related, without biochemical parameters. In most of the instruments, the validity was tested only superficially and no detailed reports regarding the application in everyday practice were given. However, the studied instruments includes algorithm as a significant component which enable decision making of the health care providers in order to execute stepwise pain management interventions. In conclusion, a need for further research to disclose pain indicators in sedated and artificial ventilated ICU-patients, continuous development of instruments and their validation in clinical practice is obvious.
