ABSTRACT

Patient-centered care is gaining widespread acceptance by the medical and lay communities and is increasingly recognized as a goal of high-quality health care delivery. Patient-centered care is based on ethical principles and aims at establishing a partnership between the health care team and patient, family member, or both in the care planning and decision-making process. Patient-centered care involves providing respectful care by tailoring management decisions to patients' beliefs, preferences, and values. A collaborative care approach can enhance patient engagement, foster shared decision-making that aligns with patient values and goals, promote more personalized and effective cardiovascular care, and potentially improve patient outcomes. The objective of this scientific statement is to inform health care professionals and stakeholders about the role and impact of patient-centered care in adult cardiovascular medicine. This scientific statement describes the background and rationale for patient-centered care in cardiovascular medicine, provides insight into patient-oriented medication management and patient-reported outcome measures, highlights opportunities and strategies to overcome challenges in patient-centered care, and outlines knowledge gaps and future directions.

ABSTRACT

Background: Family engagement in care is increasingly recognized as an essential component of optimal critical care delivery. However, family engagement strategies have traditionally involved in-person family participation. Virtual approaches to family engagement may overcome barriers to family participation in care. The objective of this study was to perform a scoping review of virtual family engagement strategies in the intensive care unit (ICU). Methods: Studies were included if they involved a virtual engagement strategy with family members of an ICU patient and reported either (1) outcomes, (2) user perspectives, and/or (3) barriers or facilitators to virtual engagement in the ICU. Study types included primary research studies and review articles. Study selection followed the Joanna Briggs Institute Methodology for Scoping Reviews guidelines without any cultural, ethnic, gender, or specific language restrictions. The source of evidence included Ovid MEDLINE, PubMed, CINAHL, and Cochrane Library databases from inception to November 17, 2023. Google scholar was searched on December 1, 2023. Data were extracted on virtual engagement strategy used, outcomes (patient-centered, family-centered, and clinical), perspectives (patient, family, and health care professional [HCP]), and reported barriers or facilitators to virtual engagement in the ICU. Results were categorized into adult or pediatric/neonatal ICU setting. Results: Virtual engagement strategies identified were virtual visitation, virtual rounding, and virtual meetings. Family and HCPs were generally supportive of virtual visitation and rounding strategies. Overall, virtual strategies were associated with improved patient, family, and HCP outcomes. There were a few randomized interventional studies evaluating the effectiveness of virtual engagement strategies. Family, HCP, technological, and institutional barriers to the implementation and conduct of virtual engagement strategies were reported. Conclusions: Virtual family engagement strategies are associated with improved outcomes for patients, family, and HCPs. Identified barriers to virtual family engagement should be addressed. Future studies are needed to evaluate the effectiveness of virtual family engagement strategies in a more rigorous manner.

ABSTRACT

Objective: To review the literature for randomized family-centered interventions with family-centered outcomes in the adult intensive care unit (ICU). Data Sources: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library database from inception until February 2023. Study Selection: We included articles involving randomized controlled trials (RCTs) in the adult critical care setting evaluating family-centered interventions and reporting family-centered outcomes. Data Extraction: We extracted data on author, year of publication, setting, number of participants, intervention category, intervention, and family-centered outcomes. Data Synthesis: There were 52 RCTs included in the analysis, mostly involving communication and receiving information (38%) and receiving care and meeting family member needs (38%). Nearly two-thirds of studies (N = 35; 67.3%) found improvements in at least 1 family-centered outcome. Most studies (N = 24/40; 60%) exploring the impact of family-centered interventions on mental health outcomes showed improvement. Improvements in patient-centered outcomes (N = 7/17; 41%) and healthcare worker outcomes (N = 1/5; 20%) were less commonly found. Conclusions: Family-centered interventions improve family-centered outcomes in the adult ICU and may be beneficial to patients and healthcare workers.

ABSTRACT

This paper describes the design of a simple and low-cost compliant low-profile prosthetic foot based on a cantilevered beam of uniform strength. The prosthetic foot is developed such that the maximum stress experienced by the beam is distributed approximately evenly across the length of the beam. Due to this stress distribution, the prosthetic foot exhibits compliant behavior not achievable through standard design approaches (e.g., designs based on simple cantilevered beams). Additionally, due to its simplicity and use of flat structural members, the foot can be manufactured at low cost. An analytical model of the compliant behavior of the beam is developed that facilitates rapid design changes to vary foot size and stiffness. A characteristic prototype was designed and constructed to be used in both a benchtop quasi-static loading test as well as a dynamic walking test for validation. The model predicted the rotational stiffness of the prototype with 5% error. Furthermore, the prototype foot was tested alongside two commercially available prosthetic feet (a low profile foot and an energy storage and release foot) in level walking experiments with a single study participant. The prototype foot displayed the lowest stiffness of the three feet (6.0, 7.1, and 10.4 Nm/deg for the prototype foot, the commercial low profile foot, and the energy storage and release foot, respectively). This foot design approach and accompanying model may allow for compliant feet to be developed for individuals with long residual limbs.

ABSTRACT

BACKGROUND: Transfemoral prosthesis users' high fall rate is related to increased injury risk, medical costs, and fear of falling. Better understanding how stumble conditions (e.g., participant age, prosthesis type, side tripped, and swing phase of perturbation) affect transfemoral prosthesis users could provide insight into response deficiencies and inform fall prevention interventions. METHODS: Six unilateral transfemoral prosthesis users experienced obstacle perturbations to their sound limb in early, mid, and late swing phase. Fall outcome, recovery strategy, and kinematics of each response were recorded to characterize (1) recoveries versus falls for transfemoral prosthesis users and (2) prosthesis user recoveries versus healthy adult recoveries. RESULTS: Out of 26 stumbles, 15 resulted in falls with five of six transfemoral prosthesis users falling at least once. By contrast, in a previously published study of seven healthy adults comprising 214 stumbles using the same experimental apparatus, no participants fell. The two oldest prosthesis users fell after every stumble, stumbles in mid swing resulted in the most falls, and prosthesis type was not related to strategy/fall outcomes. Prosthesis users who recovered used the elevating strategy in early swing, lowering strategy in late swing, and elevating or lowering/delayed lowering with hopping in mid swing, but exhibited increased contralateral (prosthetic-side) thigh abduction and trunk flexion relative to healthy controls. Falls occurred if the tripped (sound) limb did not reach ample thigh/knee flexion to sufficiently clear the obstacle in the elevating step, or if the prosthetic limb did not facilitate a successful step response after the initial sound-side elevating or lowering step. Such responses generally led to smaller step lengths, less anterior foot positioning, and more forward trunk flexion/flexion velocity in the resulting foot-strikes. CONCLUSIONS: Introducing training (e.g., muscle strength or task-specific motor skill) and/or modifying assistive devices (e.g., lower-limb prostheses or exoskeletons) may improve responses for transfemoral prosthesis users. Specifically, training or exoskeleton assistance could help facilitate sufficient thigh/knee flexion for elevating; training or prosthesis assistance could provide support-limb counteracting torques to aid in elevating; and training or prosthesis assistance could help initiate and safely complete prosthetic swing.

ABSTRACT

BACKGROUND: Early mobilization (EM) is beneficial in critical care units and in older hospitalized patients, but little is known about EM in older adults with acute cardiovascular disease. METHODS: Consecutive admissions of adults ≥80 years old to a Cardiac Intensive Care Unit (CICU) prior to and following implementation of a nurse-driven EM program were reviewed. Mobility was measured using the Level of Function (LOF) Mobility Scale, which ranges from 0 (bed immobile) to 5 (able to walk >20 meters). The primary outcome was discharge home. RESULTS: There were 412 patients included (N = 234, intervention; N = 178, preintervention). There was no difference in age between groups (overall 86.3 ± 4.8 years old) or sex (overall female N = 215, 52.2%). In the intervention group, functional impairment was present in 89 patients (38.0%) prehospitalization and in 209 patients (89.3%) on admission. Nearly half of patients (N = 107; 45.7%) improved their LOF by ≥1 during admission. Mobilization occurred during nearly all opportunities (838/850; 98.6%), and most mobility activities were completed (2,207/2,553; 86.4%). Adverse events were rare (5/2,207 activities [0.2% adverse event rate]) and transient. Patients in the intervention group were more likely than patients in the preintervention group to be discharged home (74.4 vs. 65.7%, P = 0.047, respectively) and had a lower rate of in-hospital death (6.4 vs. 14.6%, P = 0.006, respectively). There was no difference in mean length of hospital stay, 30-day emergency department visit or hospital re-admission. CONCLUSION: EM is safe in older adults in the CICU and is associated with reduced discharge to healthcare facility and in-hospital mortality.

ABSTRACT

Healthy adults employ one of three primary strategies to recover from stumble perturbations-elevating, lowering, or delayed lowering. The basis upon which each recovery strategy is selected is not known. Though strategy selection is often associated with swing percentage at which the perturbation occurs, swing percentage does not fully predict strategy selection; it is not a physical quantity; and it is not strictly a real-time measurement. The objective of this work is to better describe the basis of strategy selection in healthy individuals during stumble events, and in particular to identify a set of real-time measurable, physical quantities that better predict stumble recovery strategy selection, relative to swing percentage. To do this, data from a prior seven-participant stumble experiment were reanalyzed. A set of biomechanical measurements at/after the perturbation were taken and considered in a two-stage classification structure to find the set of measurements (i.e., features) that best explained the strategy selection process. For Stage 1 (decision between initially elevating or lowering of the leg), the proposed model correctly predicted 99.0% of the strategies used, compared to 93.6% with swing percentage. For Stage 2 (decision between elevating or delayed lowering of the leg), the model correctly predicted 94.0% of the strategies used, compared to 85.6% with swing percentage. This model uses dynamic factors of the human body to predict strategy with substantially improved accuracy relative to swing percentage, giving potential insight into human physiology as well as potentially better informing the design of fall-prevention interventions.

ABSTRACT

BACKGROUND: There are currently no validated tools that are reliable and easy to use for nurses to assess mobility in people with acute cardiovascular disease in the Cardiovascular Intensive Care Unit (CICU). METHODS: A multidisciplinary team at an academic tertiary care centre developed the Level of Function (LOF) Mobility Scale for use in a nurse-driven early progressive mobilisation in the CICU. To determine inter-rater reliability, the prehospital and admission LOF were assessed independently by two CICU nurses. Pairwise comparisons between raters were evaluated using Cohen's kappa statistic. To determine convergence validity, the LOF and Activity Measure for Post-Acute Care 6-Clicks score upon admission were compared with Spearman's correlation. To determine feasibility, a 9-item mobility scale questionnaire was distributed to CICU nurses with and without experience using the LOF Mobility Scale. The STROBE reporting guidelines were used. RESULTS: The LOF Mobility Scale had good inter-rater reliability for assessment of LOF prior to hospitalisation (N = 131, kappa = 0.66, p < .001) and at the time of CICU admission (N = 131, kappa = 0.71, p < .001). There was a moderate correlation (N = 79 observations; correlation coefficient = 0.525; p < .01) between the bedside nurses LOF and the 6-Clicks score. All nurses surveyed (N = 54; 100%) thought that the LOF Mobility Scale was clear and unambiguous, the LOFs were well-defined and the scale was an appropriate length. Nearly all of the nurses with experience using the scale (N = 22/24; 92%) felt that the scale took less than one minute to complete, compared with about half (N = 14/30; 47%) in the group of nurses without experience using the scale. CONCLUSION: The LOF Mobility Scale is reliable and feasible for mobility assessment in a nurse-driven early progressive mobilisation programme in patients with acute cardiovascular disease in the CICU. RELEVANCE TO CLINICAL PRACTICE: A nurse-driven EM programme can be implemented in the CICU.

ABSTRACT

BACKGROUND: Older adults undergoing aortic valve replacement (AVR) are at risk for malnutrition. The association between preprocedural nutritional status and midterm mortality has yet to be determined. METHODS: The FRAILTY-AVR (Frailty in Aortic Valve Replacement) prospective multicenter cohort study was conducted between 2012 and 2017 in 14 centers in 3 countries. Patients ≥70 years of age who underwent transcatheter or surgical AVR were eligible. The Mini Nutritional Assessment-Short Form was assessed by trained observers preprocedure, with scores ≤7 of 14 considered malnourished and 8 to 11 of 14 considered at risk for malnutrition. The Short Performance Physical Battery was simultaneously assessed to measure physical frailty, with scores ≤5 of 12 considered severely frail and 6 to 8 of 12 considered mildly frail. The primary outcome was 1-year all-cause mortality, and the secondary outcome was 30-day composite mortality or major morbidity. Multivariable regression models were used to adjust for potential confounders. RESULTS: There were 1158 patients (727 transcatheter AVR and 431 surgical AVR), with 41.5% females, a mean age of 81.3 years, a mean body mass index of 27.5 kg/m2, and a mean Society of Thoracic Surgeons-Predicted Risk of Mortality of 5.1%. Overall, 8.7% of patients were classified as malnourished and 32.8% were at risk for malnutrition. Mini Nutritional Assessment-Short Form scores were modestly correlated with Short Performance Physical Battery scores (Spearman R=0.31, P<0.001). There were 126 deaths in the transcatheter AVR group (19.1 per 100 patient-years) and 30 deaths in the surgical AVR group (7.5 per 100 patient-years). Malnourished patients had a nearly 3-fold higher crude risk of 1-year mortality compared with those with normal nutritional status (28% versus 10%, P<0.001). After adjustment for frailty, Society of Thoracic Surgeons-Predicted Risk of Mortality, and procedure type, preprocedural nutritional status was a significant predictor of 1-year mortality (odds ratio, 1.08 per Mini Nutritional Assessment-Short Form point; 95% CI, 1.01-1.16) and of the 30-day composite safety end point (odds ratio, 1.06 per Mini Nutritional Assessment-Short Form point; 95% CI, 1.001-1.12). CONCLUSIONS: Preprocedural nutritional status is associated with mortality in older adults undergoing AVR. Clinical trials are needed to determine whether pre- and postprocedural nutritional interventions can improve clinical outcomes in these vulnerable patients.

ABSTRACT

BACKGROUND: Noncardiovascular comorbidities and critical illness are increasing in cardiovascular intensive care units (CICUs). There are limited data comparing critical care delivery, resource utilization, and costs between contemporary CICUs and medical intensive care units (MICUs). METHODS: All CICU (n = 6967; 22 748 patient-days) and MICU (n = 10 892; 39 211 patient-days) admissions to Cedars-Sinai Medical Center, a tertiary care academic medical center, between January 2011 and December 2016 were reviewed. Both the CICU and MICU admitted patients for primary cardiovascular or medical conditions during the study period, but not for postoperative surgical care. RESULTS: Patients admitted to the CICU were more frequently older, male, and had more preexisting cardiac disease ( P < .0001). More than one-fifth (21.4%) of CICU patients had a noncardiovascular primary admission diagnosis, compared to 89.2% of MICU patients. Cardiovascular intensive care unit patients had lower Acute Physiology and Chronic Health Evaluation III scores (51.1 [19.9] vs 61.1 [24.9], P < .0001) and shorter median hospital length of stay ( P < .001), but not in-unit stay, as compared to MICU patients. Mechanical ventilation, vasopressors, inotropes, renal replacement therapy, and/or blood transfusion were required in 35.0% of CICU patients compared with 62.2% of MICU patients ( P < .0001). The unit mortality rate was lower for CICU than MICU patients (4.8% vs 13.0%, P < .0001), as was the hospital mortality rate (9.3% vs 21.6%, P < .0001). The standardized mortality ratio was 0.73 for the CICU and 0.86 for the MICU. There was no difference in the mean direct cost of care per patient-day between the CICU and MICU ($4011 USD [376] vs $3990 USD [214], P = .77). CONCLUSIONS: The burden of noncardiovascular diseases and the requirement for critical care therapies are high in contemporary CICU patients but remain lower compared to the MICU population. Our findings support the growing complexity of care in tertiary CICUs. Further studies are required to explore the association between critical care delivery and outcomes in this evolving population.

ABSTRACT

BACKGROUND: Older adults undergoing major surgery have increased protein requirements in the postoperative period, but there are limited data describing actual protein intake following cardiac surgery. METHODS AND RESULTS: We performed a prospective sub-study within a registry of older adults ≥60 years of age undergoing cardiac surgery at a tertiary care centre. A dietician administered a food frequency questionnaire before surgery and 1-4 months after surgery. In-hospital food intake was recorded by direct observation for 3 days in the early postoperative period. Food intake was analyzed to calculate the protein intake per kilogram of body weight per day (g/kg/d) during the three phases of care, compared to the dietary reference intake. Frailty was measured by a questionnaire and physical performance tests before surgery. There were 22 patients (8 females, 14 males; 59% frail) enrolled in the study with a mean age of 72.0 ± 7.8 years. The mean protein intake was 1.3 ± 0.5 g/kg/d, 0.7 ± 0.3 g/kg/d, and 1.3 ± 0.6 g/kg/d in the preoperative, early postoperative, and postdischarge periods, respectively (P < 0.0001 for early postoperative compared to other periods). Compared to the targeted dietary reference intake of 1.5 g/kg/d, there was a mean protein deficit of 0.8 g/kg/d in the early postoperative period. Only one patient (5%) met the protein dietary reference intake in the early postoperative period. CONCLUSION: In older adults undergoing cardiac surgery, dietary protein intake was substantially lower than the recommended target in the early postoperative period. Strategies to improve protein intake, particularly in frail older patients, may be considered as a therapeutic target.

ABSTRACT

BACKGROUND: The experimental study of stumble recovery is essential to better understanding the reflexive mechanisms that help prevent falls as well as the deficiencies in fall-prone populations. This study would benefit from a system that can introduce perturbations that: 1) are realistic (e.g., obstacle disrupting the foot in swing phase), 2) are unanticipated by subjects, 3) are controllable in their timing, and 4) allow for kinematic and kinetic evaluation. METHODS: A stumble perturbation system was designed that consists of an obstacle delivery apparatus that releases an obstacle onto a force-instrumented treadmill and a predictive targeting algorithm which controls the timing of the perturbation to the foot during swing phase. Seven healthy subjects were recruited to take part in an experimental protocol for system validation, which consisted of two sub-experiments. First, a perception experiment determined whether subjects could perceive the obstacle as it slid onto the treadmill belt. Second, a perturbation experiment assessed the timing accuracy of perturbations relative to a target percent swing input by the experimenter. Data from this experiment were then used to demonstrate that joint kinematics and kinetics could be computed before and after the perturbation. RESULTS: Out of 168 perception trials (24 per subject), not a single obstacle was perceived entering the treadmill by the subjects. Out of 196 perturbation trials, 190 trials successfully induced a stumble event, with a mean targeting accuracy, relative to the desired percent swing, of 25 ms (6.2% of swing phase). Joint kinematic and kinetic results were then computed for three common stumble recovery strategies and shown to be qualitatively consistent with results from prior stumble studies conducted overground. CONCLUSIONS: The stumble perturbation system successfully introduced realistic obstacle perturbations that were unanticipated by subjects. The targeting accuracy substantially reduced mistrials (i.e., trials that did not elicit a stumble) compared to previous studies. This accuracy enables stumble recovery to be studied more systematically as a function of when the perturbation occurs during swing phase. Lastly, joint kinematic and kinetic estimates allow for a comprehensive analysis of stumble recovery biomechanics.

ABSTRACT

Acquired von Willebrand syndrome (VWS) due to loss of high-molecular-weight multimers (HMWMs) has been reported with longer term mechanical devices and is associated with mucosal bleeding, a primary hemostasis type of bleeding. However, little is known whether a similar defect occurs in patients with short-term mechanical circulatory support (STMCS) devices. We reviewed von Willebrand factor (VWF) profiles in patients with STMCS devices who underwent VWS workup from December 2015 to March 2017 at an academic quaternary care hospital. There were a total of 18 patients (57.0 ± 12.7 years old; 83.3% male) including nine with mucosal bleeding and nine with decreasing hemoglobin. The STMCS devices included Impella (n = 11), Impella and right ventricular assist device (n = 2), and an extracorporeal membrane oxygenator (n = 5). The mean HMWM by quantitative VWF multimer analysis was 3.6% ± 1.3% (normal cutoff: 18-34%). In all 10 cases in which VWF activity, fibrinogen, factor VIII, or VWF antigen level were obtained, they were either normal or elevated. All cases demonstrated high normal or elevated levels of low molecular weight multimers (LMWMs). These findings are consistent with type 2 VWS (qualitative defect). This is the first study that quantitatively describes STMCS device-associated HMWM loss, which may contribute to mucosal bleeding. This finding may have implications for intraoperative management during implantation of longer term devices or heart transplantation or other surgery while on STMCS.

ABSTRACT

OBJECTIVE: To determine whether patient- and family-centered care interventions in the ICU improve outcomes. DATA SOURCES: We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library databases from inception until December 1, 2016. STUDY SELECTION: We included articles involving patient- and family-centered care interventions and quantitative, patient- and family-important outcomes in adult ICUs. DATA EXTRACTION: We extracted the author, year of publication, study design, population, setting, primary domain investigated, intervention, and outcomes. DATA SYNTHESIS: There were 46 studies (35 observational pre/post, 11 randomized) included in the analysis. Seventy-eight percent of studies (n = 36) reported one or more positive outcome measures, whereas 22% of studies (n = 10) reported no significant changes in outcome measures. Random-effects meta-analysis of the highest quality randomized studies showed no significant difference in mortality (n = 5 studies; odds ratio = 1.07; 95% CI, 0.95-1.21; p = 0.27; I = 0%), but there was a mean decrease in ICU length of stay by 1.21 days (n = 3 studies; 95% CI, -2.25 to -0.16; p = 0.02; I = 26%). Improvements in ICU costs, family satisfaction, patient experience, medical goal achievement, and patient and family mental health outcomes were also observed with intervention; however, reported outcomes were heterogeneous precluding formal meta-analysis. CONCLUSIONS: Patient- and family-centered care-focused interventions resulted in decreased ICU length of stay but not mortality. A wide range of interventions were also associated with improvements in many patient- and family-important outcomes. Additional high-quality interventional studies are needed to further evaluate the effectiveness of patient- and family-centered care in the intensive care setting.

ABSTRACT

BACKGROUND: Breast conservation therapy has become a preferred method of treating early-stage breast cancer. As care continues to evolve, certain lesions allowed less invasive treatment options. A simplified explanation of early breast cancer care is detection, biopsy, surgery, and adjuvant therapy. The authors look to challenge that algorithm for a specific type of disease. METHODS: A retrospective review was performed to identify all subcentimeter breast cancer that underwent surgery after core biopsy. These cases (n = 115) were analyzed for biopsy technique and outcome of final surgical excision to find when no residual disease was found on final pathology, potentially rendering the surgical resection an unneeded procedure. RESULTS: The authors found that 17 of 115 patients (14.8%) who underwent biopsy for subcentimeter breast cancer had no residual disease found on final surgical resection. Although the subsets were small, the largest core needle resulted in negative pathology two of three times, while the smallest gauge, never resulted in negative resection at time of surgery. CONCLUSIONS: Nearly, fifteen percent of patients were found to have no residual disease on final surgical pathology. These results were obtained when the radiologist was simply trying to get tissue diagnosis. The authors postulate that this percentage could be even higher if protocols were initiated to biopsy these small lesions with larger core biopsies and possibly alleviate the need for formal surgery in these specific, small lesion.

ABSTRACT

Frailty is increasingly recognized in older adults with cardiovascular disease, particularly in those with heart failure (HF). A growing body of evidence has shown that frailty has a negative effect on survival, hospitalizations, disability, and quality of life. Beyond frailty, additional domains captured by a comprehensive geriatric assessment contribute incremental value in predicting outcomes and identifying treatment targets. Exercise training is ideally suited to this setting as it can concomitantly improve physical frailty and HF symptoms. Multidisciplinary disease management programs offer a number of benefits for frail HF patients; invasive procedures carry a higher risk of morbidity than in non-frail counterparts, and evidence-based drugs and devices have an uncertain value and warrant further research. While more data accrues, difficult therapeutic decisions should be individualized using a shared patient-centered decision making approach.

ABSTRACT

This paper presents the design of an anthropomorphic prosthetic hand that incorporates four motor units in a unique configuration to explicitly provide both precision and conformal grasp capability. The paper describes the design of the hand prosthesis, and additionally describes the design of an embedded control system located in the palm of the hand that enables self-contained control of hand movement. Following the design description, the paper provides experimental characterizations of hand performance, including digit force capability, bandwidth of digit movement, physical properties such as size and mass, and electrical power measurements during activities of daily living.

ABSTRACT

OBJECTIVE: There is a need to understand how family engagement in the intensive care unit (ICU) impacts patient outcomes. We reviewed the literature for randomized family-centered interventions with patient-related outcomes in the adult ICU. DATA SOURCES: The MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library databases were searched from inception until July 3, 2023. STUDY SELECTION: Articles involving randomized controlled trials (RCTs) in the adult critical care setting evaluating family-centered interventions and reporting patient-related outcomes. DATA EXTRACTION: Author, publication year, setting, number of participants, intervention category, intervention, and patient-related outcomes (patient-reported, physiological, clinical) were extracted. DATA SYNTHESIS: There were 28 RCTs (12,174 participants) included. The most common intervention types were receiving care and meeting needs (N = 10) and family presence (N = 7). 16 RCTs (57%) reported ≥1 positive outcome from the intervention; no studies reported worse outcomes. Studies reported improvements in patient-reported outcomes such as anxiety, satisfaction, post-traumatic stress symptoms, depression, and health-related quality of life. RCTs reported improvements in physiological indices, adverse events, mechanical ventilation duration, analgesia use, ICU length of stay, delirium, and time to withdrawal of life-sustaining treatments. CONCLUSIONS: Nearly two-thirds of RCTs evaluating family-centered interventions in the adult ICU reported positive patient-related outcomes. KEYPOINTS: Question: Do family-centered interventions improve patient outcomes in the adult intensive care unit (ICU)? FINDINGS: The systematic review found that nearly two-thirds of randomized clinical trials of family-centered interventions in the adult ICU improved patient outcomes. Studies found improvements in patient mental health, care satisfaction, physiological indices, and clinical outcomes. There were no studies reporting worse patient outcomes. Meaning: Many family-centered interventions can improve patient outcomes.

ABSTRACT

OBJECTIVES: To review recruitment and retention strategies of randomized family-centered interventional studies in adult ICUs. DATA SOURCES: The MEDLINE, Embase, PsycINFO, CINAHL, and the Cochrane Library database from inception to February 2023. STUDY SELECTION: Randomized controlled trials with family-centered interventions in the ICU setting that reported at least one family-centered outcome that were included in our previously published systematic review. DATA EXTRACTION: For recruitment: Number of family members approached and enrolled, type of approach, location, time of day approached, whether medical team approached first, compensation offered, and type of consent. For retention: Number of family members enrolled and completed initial follow-up visit, mode of follow-up, location of follow-up visit, data collection method, timing of follow-up visits, number of follow-up visits, and compensation offered. Recruitment (participants approached/enrolled) and retention (participants enrolled/completed initial follow-up) percentage were calculated. DATA SYNTHESIS: There were 51 studies in the analysis. The mean recruitment percentage was 49.3% ± 24.3%. There were no differences in recruitment percentage by study country, ICU type, recruitment approach, or whether the medical team approached the family member first (all p > 0.05). The mean retention percentage for the initial follow-up visit was 81.6% ± 18.0%. There were no differences in retention percentage by mode of participant contact, data collection type, or follow-up location (all p > 0.05). Minimal data were available to determine the impact of time of day approached and compensation on recruitment and retention outcomes. CONCLUSIONS: About half of family members of ICU patients approached participated in trials and more than eight in ten completed the initial follow-up visit. We did not identify specific factors that impacted family recruitment or retention. There is a strong need for further studies to characterize optimal strategies to ensure family participation in clinical trials.
