RESUMO
BACKGROUND: Mechanically ventilated patients are at risk of developing inspiratory muscle weakness (IMW), which is associated with failure to wean and poor outcomes. Inspiratory muscle training (IMT) is a recommended intervention during and after extubation but has not been widely adopted in Dutch intensive care units (ICUs). OBJECTIVES: The objective of this study was to explore the potential, barriers, and facilitators for implementing IMT as treatment modality for mechanically ventilated patients. METHODS: This mixed-method, proof-of-concept study was conducted in a large academic hospital in the Netherlands. An evidence-based protocol for assessing IMW and training was applied to patients ventilated for ≥24 h in the ICU during an 8-month period in 2021. Quantitative data on completed measurements and interventions during and after ICU-stay were collected retrospectively and were analysed descriptively. Qualitative data were collected through semistructured interviews with physiotherapists executing the new protocol. Interview data were transcribed and thematically analysed. FINDINGS: Of the 301 screened patients, 11.6% (n = 35) met the inclusion criteria. Measurements were possible in 94.3% of the participants, and IMW was found in 78.8% of the participants. Ninety-six percent started training in the ICU, and 88.5% continued training after transfer to the ward. Follow-up measurements were achieved in 73.1% of the patients with respiratory muscle weakness. Twelve therapists were interviewed, of whom 41.7% regularly worked in the ICU. When exploring reasons for protocol deviation, three themes emerged: "professional barriers", "external factors", and "patient barriers". CONCLUSIONS: Implementation of measurements of and interventions for IMW showed to be challenging in this single centre study. Clinicians' willingness to change their handling was related to beliefs regarding usefulness, effectiveness, and availability of time and material. We recommend that hospitals aiming to implement IMT during or after ventilator weaning consider these professional and organisational barriers for implementation of novel, evidence-based interventions into daily clinical practice.
RESUMO
BACKGROUND: Mechanical ventilation affects the respiratory muscles, but little is known about long-term recovery of respiratory muscle weakness (RMW) and potential associations with physical functioning in survivors of critical illness. The aim of this study was to investigate the course of recovery of RMW and its association with functional outcomes in patients who received mechanical ventilation. METHODS: We conducted a prospective cohort study with 6-month follow-up among survivors of critical illness who received ≥ 48 hours of invasive mechanical ventilation. Primary outcomes, measured at 3 timepoints, were maximal inspiratory and expiratory pressures (MIP/MEP). Secondary outcomes were functional exercise capacity (FEC) and handgrip strength (HGS). Longitudinal changes in outcomes and potential associations between MIP/MEP, predictor variables, and secondary outcomes were investigated through linear mixed model analysis. RESULTS: A total of 59 participants (male: 64%, median age [IQR]: 62 [53-66]) were included in this study with a median (IQR) ICU and hospital length of stay of 11 (8-21) and 35 (21-52) days respectively. While all measures were well below predicted values at hospital discharge (MIP: 68.4%, MEP 76.0%, HGS 73.3% of predicted and FEC 54.8 steps/2m), significant 6-month recovery was seen for all outcomes. Multivariate analyses showed longitudinal associations between older age and decreased MIP and FEC, and longer hospital length of stay and decreased MIP and HGS outcomes. In crude models, significant, longitudinal associations were found between MIP/MEP and FEC and HGS outcomes. While these associations remained in most adjusted models, an interaction effect was observed for sex. CONCLUSION: RMW was observed directly after hospital discharge while 6-month recovery to predicted values was noted for all outcomes. Longitudinal associations were found between MIP and MEP and more commonly used measures for physical functioning, highlighting the need for continued assessment of respiratory muscle strength in deconditioned patients who are discharged from ICU. The potential of targeted training extending beyond ICU and hospital discharge should be further explored.

BACKGROUND: Survivors of critical illness experience long-term functional challenges, which are complex, heterogeneous, and multifactorial in nature. Although the importance of rehabilitation interventions after intensive care unit (ICU) discharge is universally recognized, evidence on feasibility and effectiveness of home-based rehabilitation programs is scarce and ambiguous. This study investigates the feasibility of an interdisciplinary rehabilitation program designed for patients with Post-Intensive Care Syndrome (PICS) who are discharged home. METHODS: A mixed method, non-randomized, prospective pilot feasibility study was performed with a 6-month follow-up, comparing the intervention (REACH) with usual care. REACH was provided by trained professionals and included a patient-centered, interdisciplinary approach starting directly after hospital discharge. Primary outcomes were patient safety, satisfaction, adherence, referral need and health care usage. Secondary outcomes, measured at 3 timepoints, were functional exercise capacity, self-perceived health status, health-related quality of life (HRQoL), return to work and psychotrauma. Risk of undernutrition was assessed at baseline. RESULTS: 43 patients with a median mechanical ventilation duration of 8 (IQR:10) days, were included in the study and 79.1% completed 6-month follow-up. 19 patients received the intervention, 23 received usual care. Groups were similar for gender distribution and ICU length of stay. No adverse events occurred. REACH participants showed higher satisfaction with treatment and reported more allied health professional visits, while the usual care group reported more visits to medical specialists. Qualitative analysis identified positive experiences among REACH-professionals related to providing state-of-the-art interventions and sharing knowledge and expertise within an interprofessional network. Similar recovery was seen between groups on all secondary outcomes, but neither group reached reference values for HRQoL at 6 months. Larger return to work rates were seen in the REACH group. Prevalence of undernutrition at hospital discharge was high in both groups (> 80%), warranting the need for careful tuning of physical therapy and nutritional interventions. CONCLUSIONS: This study shows that providing early, home-based rehabilitation interventions for patients with PICS-related symptoms is feasible and perceived positively by patients and professionals. When provided in an interdisciplinary collaborative network state of the art, person-centered interventions can be tailored to individual needs potentially increasing patient satisfaction, adherence, and efficacy.

Purpose: The aim of this study was to develop practical recommendations for physiotherapy for survivors of critical illness after hospital discharge. Methods: A modified Delphi consensus study was performed. A scoping literature review formed the basis for three Delphi rounds. The first round was used to gather input from the panel to finalize the survey for the next two rounds in which the panel was asked to rank each of the statements on an ordinal scale with the objective to reach consensus. Consensus was defined as a SIQR of ≤ 0.5. Ten Dutch panelists participated in this study: three primary care physiotherapists, four intensive care physiotherapists, one occupational therapist, one ICU-nurse and one former ICU-patient. All involved professionals have treated survivors of critical illness. Our study was performed in parallel with an international Delphi study with hospital-based health-care professionals and researchers. Results: After three Delphi rounds, consensus was reached on 95.5% of the statements. This resulted in practical recommendations for physiotherapy for critical illness survivors in the primary care setting. The panel agreed that the handover should include information on 14 items. Physiotherapy treatment goals should be directed toward improvement of aerobic capacity, physical functioning, activities in daily living, muscle strength, respiratory and pulmonary function, fatigue, pain, and health-related quality of life. Physiotherapy measurements and interventions to improve these outcomes are suggested. Conclusion: This study adds to the knowledge on post-ICU physiotherapy with practical recommendations supporting clinical decision-making in the treatment of survivors of critical illness after hospital discharge.

OBJECTIVE: The aim of this work was to compare the patient-reported functional health status with regard to physical, psychological, and social functioning of intensive care unit (ICU) survivors with and without ICU-acquired weakness (ICU-AW). DESIGN: Single-center prospective study in ICU patients who were mechanically ventilated for more than 2 days and who survived to ICU discharge. Functional health status was assessed at 3, 6, and 12 months after ICU discharge, using the Sickness Impact Profile 68 (SIP68). The independent effect of ICU-AW on impaired functional status (SIP68 scores > 20) was analyzed using a multivariable logistic regression model. RESULTS: A total of 133 patients were included, 60 with ICU-AW. Intensive care unit-acquired weakness was an independent predictor for impaired functional health status at 3 months after ICU discharge (odds ratio, 0.27; 95% confidence interval, 0.08-0.94; P = 0.04) but not at 6 and 12 months. Physical functioning was significantly more impaired in patients with ICU-AW at 3 and 12 months. Psychological functioning and social functioning were comparable between the groups, with little restrictions in psychological functioning, and severe long-lasting restrictions in social functioning. CONCLUSIONS: The findings of this study urge the need to develop interdisciplinary rehabilitation interventions for ICU survivors, which should be continued after hospital discharge.

BACKGROUND: Many intensive care unit survivors (ICU) are confronted with undesirable and long-lasting impairments in physical, cognitive, and mental health, but not only patients are at risk of developing this post-intensive care syndrome (PICS). Family members can experience symptoms of depression, anxiety, and posttraumatic stress disorder (PTSD). This cluster of complications is called PICS-family. OBJECTIVE: To describe the level of caregiver strain and posttraumatic stress-related symptoms in relatives of ICU survivors. METHODS: We conducted a cohort study in a general hospital between July 2010 and May 2014. Relatives of ICU survivors, mechanically ventilated for > 48 h in the ICU, were asked to complete a questionnaire 3 months after discharge from critical care. Symptoms of PTSD and caregiving concerns were assessed using the Trauma Screening Questionnaire and the Caregiver Strain Index (CSI). RESULTS: A total of 94 relatives visiting our post-ICU clinic completed the questionnaires. Twenty-one percent of the caregivers had a CSI score of 7 or more, indicating high levels of strain. Six percent had CSI scores indicating severe strain (CSI > 10). PTSD-related symptoms were seen in 21% of the caregivers. The mean time spent on caregiving was 10 h (interquartile range 6-17 h) per week. CONCLUSION: This study shows that relatives of ICU survivors could experience strain 3 months after hospital discharge and are at risk of developing PTSD-related symptoms. This complements existing data that relatives are at risk of psychological symptoms. Knowledge can lead to improvements and means to prevent these symptoms. (PsycINFO Database Record

OBJECTIVE: The purpose of this study was to explore coping styles among intensive care unit (ICU) survivors and investigate the association between coping style and quality of life (QOL). METHOD: In this cross-sectional multicenter study, 150 adult patients who were mechanically ventilated in an ICU for ≥2 days and discharged to their homes were invited to visit the post-ICU clinic 3 months after discharge. Before the post-ICU visit, the patients completed questionnaires regarding their QOL, coping style, and psychological distress. Coping style was assessed using the Coping Inventory for Stressful Situations (CISS-21; de Ridder & van Heck, 2004), which measures task-oriented coping, emotion-oriented coping, and avoidance coping styles. QOL was assessed using the Physical Component Score (PCS) and Mental Component Score (MCS) derived from the 36-item Short Form Health Survey (SF-36; Aaronson et al., 1998). Univariate and multivariate linear regressions were performed. RESULTS: One hundred four patients (mean age = 59 years; 71 men, 33 women) completed the questionnaires (response rate = 69%). The highest CISS-21 subscale mean was found in the Task-Oriented subscale (21.3), followed by the Avoidance Coping subscale (18.7) and the Emotion-Oriented subscale (15.2). Emotion-oriented coping style was independently associated with reduced mental health (i.e., SF-36 MCS), but not with physical functioning (i.e., SF-36 PCS). CONCLUSIONS: An emotion-oriented coping style is associated with worse mental health among Dutch ICU survivors. Additional research is needed in order to determine the precise role that coping style plays in the long-term recovery of ICU survivors. (PsycINFO Database Record

INTRODUCTION: ICU-acquired weakness is thought to mediate physical impairments in survivors of critical illness, but few studies have investigated this thoroughly. The purpose was to investigate differences in post-ICU mortality and physical functioning between patients with and without ICU-acquired weakness at 6 months after ICU discharge. METHOD: ICU patients, mechanically ventilated ≥ 2 days, were included in a single-center prospective observational cohort study. ICU-acquired weakness was diagnosed when the average Medical Research Council score was <4 in awake and attentive patients. Post-ICU mortality was recorded until 6 months after ICU discharge; in surviving patients, physical functioning was assessed using the Short-Form Health Survey physical functioning domain. The independent effect of ICU-acquired weakness on post-ICU mortality was analyzed using a multivariable Cox proportional hazards model. The independent effect of ICU-acquired weakness on the physical functioning domain score was analyzed using a multivariable linear regression model. RESULTS: Of the 156 patients included, 80 had ICU-acquired weakness. Twenty-three patients died in the ICU (20 with ICU-acquired weakness); during 6 months follow-up after ICU discharge another 25 patients died (17 with ICU-acquired weakness). Physical functioning domain scores were available for 96 survivors (39 patients with ICU-acquired weakness). ICU-acquired weakness was independently associated with an increase in post-ICU mortality (hazard ratio 3.6, 95% confidence interval, 1.3 to 9.8; P = 0.01) and with a decrease in physical functioning (ß: -16.7 points; 95% confidence interval, -30.2 to -3.1; P = 0.02). CONCLUSION: ICU-acquired weakness is independently associated with higher post-ICU mortality and with clinically relevant lower physical functioning in survivors at 6 months after ICU discharge.

OBJECTIVE: To develop evidence-based recommendations for effective and safe diagnostic assessment and intervention strategies for the physiotherapy treatment of patients in intensive care units. METHODS: We used the EBRO method, as recommended by the 'Dutch Evidence Based Guideline Development Platform' to develop an 'evidence statement for physiotherapy in the intensive care unit'. This method consists of the identification of clinically relevant questions, followed by a systematic literature search, and summary of the evidence with final recommendations being moderated by feedback from experts. RESULTS: Three relevant clinical domains were identified by experts: criteria to initiate treatment; measures to assess patients; evidence for effectiveness of treatments. In a systematic literature search, 129 relevant studies were identified and assessed for methodological quality and classified according to the level of evidence. The final evidence statement consisted of recommendations on eight absolute and four relative contra-indications to mobilization; a core set of nine specific instruments to assess impairments and activity restrictions; and six passive and four active effective interventions, with advice on (a) physiological measures to observe during treatment (with stopping criteria) and (b) what to record after the treatment. CONCLUSIONS: These recommendations form a protocol for treating people in an intensive care unit, based on best available evidence in mid-2014.

BACKGROUND: An early diagnosis of ICU-acquired weakness (ICU-AW) is difficult because disorders of consciousness frequently preclude muscle strength assessment. In this study, we investigated feasibility and accuracy of electrophysiological recordings to diagnose ICU-AW early in non-awake critically ill patients. METHODS: Newly admitted patients, mechanically ventilated ≥2 days and unreactive to verbal stimuli, were included in this study. Electrophysiological recordings comprised nerve conduction studies (NCS) of three nerves and, if coagulation was normal, myography in three muscles. Upon awakening, strength was assessed (ICU-AW: average Medical Research Council score <4), blinded for electrophysiological recordings. Feasibility was expressed as the percentage of recordings that were both possible and had sufficient technical quality. Diagnostic accuracy of feasible (i.e., feasibility >75 %) recordings was analyzed based on cut-off values from healthy controls and from critically ill patients with and without ICU-AW. RESULTS: Thirty-five patients were included (17 with ICU-AW). Recordings were obtained on day 4 (IQR: 3-6). Feasibility was acceptable for ulnar and peroneal nerve recordings, and low for sural recordings and myography. Diagnostic accuracy based on cut-off values from healthy controls was low. When using cut-off values from critically ill patients with and without ICU-AW, the peroneal compound muscle action potential amplitude and ulnar sensory nerve action potential amplitude had good diagnostic accuracy. CONCLUSION: Nerve conduction studies of the ulnar and peroneal nerve are feasible in critically ill patients. The diagnostic accuracy is low using cut-off values from healthy controls. Cut-off values validated specifically for discrimination between critically ill patients with and without ICU-AW may improve diagnostic accuracy.

INTRODUCTION: An early diagnosis of Intensive Care Unit-acquired weakness (ICU-AW) using muscle strength assessment is not possible in most critically ill patients. We hypothesized that development of ICU-AW can be predicted reliably two days after ICU admission, using patient characteristics, early available clinical parameters, laboratory results and use of medication as parameters. METHODS: Newly admitted ICU patients mechanically ventilated ≥2 days were included in this prospective observational cohort study. Manual muscle strength was measured according to the Medical Research Council (MRC) scale, when patients were awake and attentive. ICU-AW was defined as an average MRC score <4. A prediction model was developed by selecting predictors from an a-priori defined set of candidate predictors, based on known risk factors. Discriminative performance of the prediction model was evaluated, validated internally and compared to the APACHE IV and SOFA score. RESULTS: Of 212 included patients, 103 developed ICU-AW. Highest lactate levels, treatment with any aminoglycoside in the first two days after admission and age were selected as predictors. The area under the receiver operating characteristic curve of the prediction model was 0.71 after internal validation. The new prediction model improved discrimination compared to the APACHE IV and the SOFA score. CONCLUSION: The new early prediction model for ICU-AW using a set of 3 easily available parameters has fair discriminative performance. This model needs external validation.
