Plasma HMGB1 levels and physical performance in ICU survivors.

PURPOSE: Physical impairment after critical illness is recognized as a part of the post-intensive care syndrome (PICS). About one third of intensive care unit (ICU) survivors suffer from long-term physical disability, yet the underlying pathophysiological mechanisms remain poorly understood. The pro-inflammatory alarmin, high mobility group box 1 (HMGB1), promotes muscle dysfunction in experimental models, and HMGB1 stays elevated in some patients after ICU discharge. Accordingly, we investigated the relationship between HMGB1 plasma levels and physical performance in ICU survivors. METHODS: Prospective cohort study of 100 ICU survivors from the general ICU at the Karolinska University Hospital, Sweden. Patients returned for follow up at 3 (58 patients) and 6 months (51 patients) after ICU discharge. Blood samples were collected, and a 6-minute walk test (6-MWT), a handgrip-strength test (HST), and a timed-stands test (TST) were performed. RESULTS: Compared to reference values of the different physical tests, 16% of patients underperformed at all tests at 3 months and 12% at 6 months. All test results, except hand-grip strength left, improved significantly over the follow-up period (P < .05). There was no significant association between plasma HMGB1 levels at 3 and 6 months and scores on the three tests (6-MWT, TST, and HST) (P = .50-0.69). CONCLUSION: In this follow-up study of ICU survivors, we found no significant association between plasma HMGB1 levels and physical performance. Additional follow-up studies of HMGB1 plasma levels and muscle function in ICU survivors are still warranted. EDITORIAL COMMENT: HMGB-1, a marker of cell damage and activation, is known to increase in ICU patients. In study participants at 3- to 6-month post-ICU stay, HMGB-1 levels were still elevated, although no association to the primary outcome, physical performance, was found. Mechanisms for failure to recover physical performance post-ICU remain unclear, and investigations into cause of post-intensive care syndrome need to continue.

First initiation of mobilization out of bed after cardiac surgery - an observational cross-sectional study in Sweden.

BACKGROUND: Cardiac surgery is associated with a period of postoperative bed rest. Although early mobilization is a vital component of postoperative care, for preventing complications and enhancing physical recovery, there is limited data on routine practices and optimal strategies for early mobilization after cardiac surgery. The aim of the study was to define the timing for the first initiation of out of bed mobilization after cardiac surgery and to describe the type of mobilization performed. METHODS: In this observational study, the first mobilization out of bed was studied in a subset of adult cardiac surgery patients (n = 290) from five of the eight university hospitals performing cardiothoracic surgery in Sweden. Over a five-week period, patients were evaluated for mobilization routines within the initial 24 h after cardiac surgery. Data on the timing of the first mobilization after the end of surgery, as well as the duration and type of mobilization, were documented. Additionally, information on patient characteristics, anesthesia, and surgery was collected. RESULTS: A total of 277 patients (96%) were mobilized out of bed within the first 24 h, and 39% of these patients were mobilized within 6 h after surgery. The time to first mobilization after the end of surgery was 8.7 ± 5.5 h; median of 7.1 [4.5-13.1] hours, with no significant differences between coronary artery bypass grafting, valve surgery, aortic surgery or other procedures (p = 0.156). First mobilization session lasted 20 ± 41 min with median of 10 [1-11]. Various kinds of first-time mobilization, including sitting on the edge of the bed, standing, and sitting in a chair, were revealed. A moderate association was found between longer intubation time and later first mobilization (ρ = 0.487, p < 0.001). Additionally, there was a moderate correlation between the first timing of mobilization duration of the first mobilization session (ρ = 0.315, p < 0.001). CONCLUSIONS: This study demonstrates a median time to first mobilization out of bed of 7 h after cardiac surgery. A moderate correlation was observed between earlier timing of mobilization and shorter duration of the mobilization session. Future research should explore reasons for delayed mobilization and investigate whether earlier mobilization correlates with clinical benefits.

First mobilisation after abdominal and cardiothoracic surgery: when is it actually performed? A national, multicentre, cross-sectional study.

OBJECTIVES: Knowledge of clinical practice regarding mobilisation after surgery is lacking. This study therefore aimed to reveal current mobilisation routines after abdominal and cardiothoracic surgery and to identify factors associated with mobilisation within 6 hours postoperatively. DESIGN: A prospective observational national multicentre study. SETTING: 18 different hospitals in Sweden. PARTICIPANTS: 1492 adult patients undergoing abdominal and cardiothoracic surgery with duration of anaesthesia>2 hours. PRIMARY AND SECONDARY OUTCOMES: Primary outcome was time to first postoperative mobilisation. Secondary outcomes were the type and duration of the first mobilisation. Data were analysed using multivariate logistic regression and general structural equation modelling, and data are presented as ORs with 95% CIs. RESULTS: Among the included patients, 52% were mobilised to at least sitting on the edge of the bed within 6 hours, 70% within 12 hours and 96% within 24 hours. Besides sitting on the edge of the bed, 76% stood up by the bed and 22% were walking away from the bedside the first time they were mobilised. Patients undergoing major upper abdominal surgery required the longest time before mobilisation with an average time of 11 hours post surgery. Factors associated with increased likelihood of mobilisation within 6 hours of surgery were daytime arrival at the postoperative recovery unit (OR: 5.13, 95% CI: 2.16 to 12.18), anaesthesia <4 hours (OR: 1.68, 95% CI: 1.17 to 2.40) and American Society of Anaesthesiologists (ASA) classification 1-2, (OR: 1.63, 95% CI: 1.13 to 2.36). CONCLUSIONS: In total, 96% if the patients were mobilised within 24 hours after surgery and 52% within 6 hours. Daytime arrival at the postoperative recovery unit, low ASA classification and shorter duration of anaesthesia were associated with a shorter time to mobilisation.

Mobilization Started Within 2 Hours After Abdominal Surgery Improves Peripheral and Arterial Oxygenation: A Single-Center Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to investigate if mobilization out of bed, within 2 hours after abdominal surgery, improved participants' respiratory function and whether breathing exercises had an additional positive effect. METHODS: Participants were 214 consecutively recruited patients who underwent elective open or robot-assisted laparoscopic gynecological, urological, or endocrinological abdominal surgery with an anesthetic duration of >2 hours. They were recruited to a randomized controlled trial. Immediately after surgery, patients were randomly assigned to 1 of 3 groups: mobilization (to sit in a chair) and standardized breathing exercises (n = 73), mobilization (to sit in a chair) only (n = 76), or control (n = 65). The interventions started within 2 hours after arrival at the postoperative recovery unit and continued for a maximum of 6 hours. The primary outcomes were differences in peripheral oxygen saturation (SpO2, as a percentage) and arterial oxygen pressure (PaO2, measured in kilopascals) between the groups. Secondary outcomes were arterial carbon dioxide pressure, spirometry, respiratory insufficiency, pneumonia, and length of stay. RESULTS: Based on intention-to-treat analysis (n = 214), patients who received mobilization and breathing exercises had significantly improved SpO2 (mean difference [MD] = 2.5%; 95% CI = 0.4 to 4.6) and PaO2 (MD = 1.40 kPa; 95% CI = 0.64 to 2.17) compared with the controls. For mobilization only, there was an increase in PaO2 (MD = 0.97 kPa; 95% CI = 0.20 to 1.74) compared with the controls. In the per-protocol analysis (n = 201), there were significant improvements in SpO2 and PaO2 for both groups receiving mobilization compared with the controls. Secondary outcome measures did not differ between groups. CONCLUSION: Mobilization out of bed, with or without breathing exercises, within 2 hours after elective abdominal surgery improved SpO2 and PaO2. IMPACT: The respiratory effect of mobilization (out of bed) immediately after surgery has not been thoroughly evaluated in the literature. This study shows that mobilization out of bed following elective abdominal surgery can improve SpO2 and PaO2. LAY SUMMARY: Mobilization within 2 hours after elective abdominal surgery, with or without breathing exercises, can improve patients' respiratory function.

Cross-cultural adaptation and inter-rater reliability of the Swedish version of the Chelsea critical care assessment tool (CPAX-Swe) in critically ill patients.

OBJECTIVES: To translate and culturally adapt the Chelsea Critical Care Physical Assessment Tool into Swedish and to test the inter-rater reliability of the Swedish version in critically ill patients. DESIGN: This is an observational study. METHODS: Translation and cross-cultural adaptation was performed in line with international recommendations, including forward and backward translation and expert round table discussions. The inter-rater reliability of the Chelsea Critical Care Physical Assessment Tool - Swedish was then explored in 50 critically ill adult patients, pragmatically recruited, in a University Hospital clinical setting. Reliability was calculated using intraclass correlation coefficient for aggregated scores and quadratic weighted Cohen's kappa analysis for individual items. RESULTS: The expert round table discussion group agreed that the translation was a satisfactory equivalent to the original version and applicable for use within the clinical setting. Reliability of aggregated scores and individual items were very good (intraclass correlation coefficient of 0.97 and quadric weighted kappa values ranging from 0.88 to 0.98). The measurement error for aggregated scores was low, with a standard error of measurement of 1.79, smallest detectable change of 4.95, and limits of agreement of 5.20 and -4.76. The percentage agreement for individual items ranged from 64% to 88%. CONCLUSION: The Chelsea Critical Care Physical Assessment Tool - Swedish was found applicable and appropriate for assessment of functioning in critically ill patients in an acute setting in Sweden, and it displayed high inter-rater reliability. This implies that the Swedish version can be used as assessment tool within intensive care and acute wards in Sweden.Implications for rehabilitationThere is a lack of validated instruments to test the functional status of critically ill patients in Sweden.The Chelsea Critical Care Physical Assessment Tool is validated and reliable in English.The Chelsea Critical Care Physical Assessment Tool - Swedish is considered reliable for use by physiotherapist in intensive care settings in Sweden.The Swedish version is feasible for use within clinical practice due to its simplicity and strong clinical relevance.

"I Have Everything to Win and Nothing to Lose": Patient Experiences of Mobilization Out of Bed Immediately After Abdominal Surgery.

OBJECTIVE: Early mobilization is advocated for patients going through abdominal surgery; however, little is known about the patient experience of being mobilized immediately after surgery. The purpose of this study was to explore patient experiences of mobilization immediately after elective abdominal cancer surgery. METHODS: This interview study used qualitative content analysis. With the use of purposeful sampling, a total of 23 participants who had been mobilized immediately after abdominal surgery were recruited at a university hospital in Stockholm, Sweden. Individual face-to-face interviews were conducted within 1 to 4 days after surgery and took place at the surgical ward where the participants were treated. A semi-structured guide was used. All interviews were audio recorded and transcribed verbatim. RESULTS: The content analysis revealed 3 categories that emerged into 1 overarching theme: "to do whatever it takes to get home earlier." The participants experienced that mobilization out of bed had an impact on their physical and mental well-being. Motivation and the experiences of themselves and others were factors that affected patient attitudes toward early mobilization. Preparation and competent caregivers were emphasized as important factors that enabled the patient to feel safe and confident during mobilization. CONCLUSIONS: Patients experienced mobilization as an important part of the care that had an impact on recovery and well-being, physically as well as mentally, both immediately and over time. IMPACT: As this is the first study to our knowledge to investigate patient experiences of mobilization immediately after abdominal surgery, this information can be used to support the development of early mobilization protocols in hospital settings.

Screening and treatment of problems after intensive care: a descriptive study of multidisciplinary follow-up.

OBJECTIVES: To describe a multidisciplinary intensive care follow-up and the methods used for identifying and managing physical and psychological problems in ICU survivors. METHODS: Patients treated>four days in an intensive care unit (ICU) were invited three, six and 12 months after intensive care for screening of physical problems with function tests and psychological problems with the Impact of Event Scale (IES) and the Hospital Anxiety and Depression Scale (HADS). RESULTS: 40 of 61 patients had clinically impaired physical function, with no ongoing physical rehabilitation at three months. Twenty-two patients received specific training instructions and 18 patients were referred for physiotherapy. 34 of 61 patients had symptoms of moderate to severe posttraumatic stress and/or symptoms of clinically significant anxiety or depression. Twelve patients accepted referral for psychiatric evaluation and treatment. CONCLUSION: Multidisciplinary follow-up after intensive care can be of value in identifying untreated physical and psychological problems in ICU survivors. Liaison with specialists enables referral for identified problems. Patients screened and treated in the first six months appear to have little need for further follow-up after intensive care.
