Abstract
The study's purpose was to analyze outcomes of patients with severe behavioural disturbances after acquired brain injury (ABI) in order to identify predictors of discharge destination from a specialized unit (SU) of a Swiss neurorehabilitation facility. Retrospective analysis of 85 patients. Potential predictors of the main outcome discharge destination were assessed with a correlation analysis. The Agitation Behaviour Scale (ABS), Functional Independence Measure (FIM), length of stay (LOS) and pre-living situation were tested in a logistic regression analysis. Twenty-nine patients were institutionalized and 56 patients went home. Discharge destination was significantly correlated to ABS score at discharge from SU (rs = -.33, p = .002), total FIM score on admission to the SU (rs = .25, p = .022), total FIM score at discharge from the SU (rs = .37, p < .001), LOS at the SU (rs = -.36, p = .001), and LOS after discharge of the SU (rs = .36, p = .001). Multivariate analysis showed that FIM scores at discharge (OR = 1.03, p = .008), and LOS at SU (OR = 0.98, p = .017) predicted discharge destination significantly. FIM or LOS may be important predictors in planning discharge destination in patients with severe behavioural disturbances. Further prospective studies are critically needed to better understand the complexity of interactions amongst important predictive factors.

Bae SW, Lee MY. Association Between Initiation of Rehabilitation and Length of Hospital Stay for Workers with Moderate to Severe Work-Related Traumatic Brain Injury. Saf Health Work 2023; 14:229-236. [PMID: 37389320 PMCID: PMC10300463 DOI: 10.1016/j.shaw.2023.04.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 03/28/2023] [Accepted: 04/03/2023] [Indexed: 07/01/2023] Open
Abstract
Background In workers with moderate to severe work-related traumatic brain injury (wrTBI), this study aimed to investigate the effect of the timing of rehabilitation therapy initiation on the length of hospital stay and the factors that can influence this timing. Methods We used data obtained from the Republic of Korea's nationwide Workers' Compensation Insurance. In the Republic of Korea, between the years 2010 and 2019, a total of 26,324 workers filed a claim for compensation for moderate to severe wrTBI. Multiple regression modeling was performed to compare the length of hospital stay according to the timing of rehabilitation therapy initiation following wrTBI. According to the timing of the initiation of rehabilitation therapy following TBI, the proportions of healthcare institutions that provided medical care during each admission step were compared. Results The length of hospital stay for workers who started rehabilitation therapy within 90 days was significantly shorter than that for workers who started rehabilitationment were first admitted to tertiary hospitals. Approximately 39% of patients who received delayed rehabilitation treatment were first admitted to general hospitals, and 28.5% were first admitted to primary hospitals. Conclusions Our findings demonstrate the importance of early rehabilitation initiation and that the type of healthcare institution that the patient is first admitted to after wrTBI may influence the timing of rehabilitation initiation. The results of this study also emphasize the need to establish a Worker's Compensation Insurance-specialized rehabilitation healthcare delivery system.

Abstract
BACKGROUND Patients who were incarcerated were disproportionately impacted by COVID-19 compared to the general public. Further, the impact of multidisciplinary rehabilitation assessments and interventions on the outcomes of patients admitted to the hospital with COVID-19 is limited. OBJECTIVE To compare functional outcomes of oral intake, mobility, and activity between inmates and non-inmates who were diagnosed with COVID-19 and examine the relationships among these functional measures and discharge destination. METHODS A retrospective analysis was performed on patients admitted to the hospital for COVID-19 at a large academic medical center. Scores on functional measures including Functional Oral Intake Scale (FOIS) and Activity Measure for Post-Acute Care (AM-PAC) were collected and compared between inmates and non-inmates. Binary logistic regression models were used to evaluate the odds of 1) whether patients were discharged to the same place they were admitted and 2) patients being discharged with a total oral diet with no restrictions. Independent variables were considered significant if the 95% CIs of the odds ratios (ORs) did not include 1.0. RESULTS A total of 83 patients (inmates, n=38; non-inmates, n=45) were included in the final analysis. There were no differences between inmates and non-inmates on initial (P=.39) and final FOIS scores (P=.35) or on initial, final, or change scores (P>.05) on the AM-PAC. When examining separate regression models using AM-PAC mobility or AM-PAC activity scores as independent variables, greater age upon admission decreased the odds (OR=0.922; 95%CI=0.875 to 0.972 and OR=0.918; 95%CI=0.871 to 0.968) of patients being discharged with a total oral diet with no restrictions. The following factors increased the odds of patients being discharged to the same place they were admitted from: being an inmate (OR=5.285; 95%CI= 1.334 to 20.931) and (OR=6.083; 95%CI=1.548 to 23.912); "Other" race (OR=7.596; 95%CI=1.203 to 47.968) and (OR=8.515; 95%CI=1.311 to 55.291); and female sex (OR=4.671; 95%CI=1.086 to 20.092) and (OR=4.977; 95%CI=1.146 to 21.615). CONCLUSIONS Results from this study provide an opportunity to learn how functional measures may be used to better understand discharge outcomes in both inmate and non-inmate patients admitted to the hospital with COVID-19 during the initial period of the pandemic.

Abstract
Introduction Model of Human and Occupational Screening Tool (MOHOST) is a scale used to assess occupational functioning in mental health inpatients which can inform suitable post-discharge placements. However, there is little research on the relationship between scores on Motivation for Occupation (MO) and Pattern of Occupation (PO) subscales of the MOHOST and types of discharge placement. Method The records of all patients discharged over a 2-year period from a male psychiatric rehabilitation unit were examined. All patients had undergone MOHOST assessments; however, these scores were not a factor in their discharge placement selection. Analyses were done on types of discharge placements (transfer to another psychiatric unit or community discharge) versus predischarge scores in MO and PO of MOHOST. Results N = 20 and average length of stay was 23 months. There was positive correlation between MO and PO scores and discharge placements (rs = 0.66, p = 0.002; rs = 0.67 and p = 0.001, respectively). Using ordinal logistic regression, for each unit increase of negative score in PO, there was 0.68 increase in the log odds of more restrictive discharge placements, p = 0.008. Conclusion The study suggests that MOHOST is a useful tool in determining suitable placements for patients being discharged or transferred from psychiatric rehabilitation units.

Abstract
For centuries, the study of traumatic brain injury (TBI) has been centred on historical observation and analyses of personal, social, and environmental processes, which have been examined separately. Today, computation implementation and vast patient data repositories can enable a concurrent analysis of personal, social, and environmental processes, providing insight into changes in health status transitions over time. We applied computational and data visualization techniques to categorize decade-long health records of 235,003 patients with TBI in Canada, from preceding injury to the injury event itself. Our results highlighted that health status transition patterns in TBI emerged along with the projection of comorbidity where many disorders, social and environmental adversities preceding injury are reflected in external causes of injury and injury severity. The strongest associations between health status preceding TBI and health status at the injury event were between multiple body system pathology and advanced age-related brain pathology networks. The interwoven aspects of health status on a time continuum can influence post-injury trajectories and should be considered in TBI risk analysis to improve prevention, diagnosis, and care.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a leading cause of adult morbidity and mortality. Individuals with TBI have impairments in both cognitive and motor domains. Motor improvements post-TBI are attributable to adaptive neuroplasticity and motor learning. Majority of the studies focus on remediation of balance and mobility issues. There is limited understanding on the use of interventions for upper limb (UL) motor improvements in this population. OBJECTIVE We examined the evidence regarding the effectiveness of different interventions to augment UL motor improvement after a TBI. METHODS We systematically examined the evidence published in English from 1990-2020. The modified Downs and Black checklist helped assess study quality (total score: 28). Studies were classified as excellent: 24-28, good: 19-23, fair: 14-18, and poor: ≤13 in quality. Effect sizes helped quantify intervention effectiveness. RESULTS Twenty-three studies were retrieved. Study quality was excellent (n = 1), good (n = 5) or fair (n = 17). Interventions used included strategies to decrease muscle tone (n = 6), constraint induced movement therapy (n = 4), virtual reality gaming (n = 5), non-invasive stimulation (n = 3), arm motor ability training (n = 1), stem cell transplant (n = 1), task-oriented training (n = 2), and feedback provision (n = 1). Motor impairment outcomes included Fugl-Meyer Assessment, Modified Ashworth Scale, and kinematic outcomes (error and movement straightness). Activity limitation outcomes included Wolf Motor Function Test and Motor Activity Log (MAL). Effect sizes for majority of the interventions ranged from medium (.5-.79) to large (≥.8). Only ten studies included retention testing. CONCLUSION There is preliminary evidence that using some interventions may enhance UL motor improvement after a TBI. Answers to emergent questions can help select the most appropriate interventions in this population.

Abstract
PURPOSE To identify facilitators and barriers associated with returning home for older adults having received inpatient rehabilitation after traumatic brain injury (TBI). METHODS A qualitative design was used. Five older patients with TBI and four family caregivers were interviewed and six healthcare professionals participated in a focus group. RESULTS Main facilitators to returning home highlighted by all participants were: (1) Patient's adequate health condition and functional status, (2) Access to health and other services at home, (3) Availability of help from a family caregiver. Conversely, if one of these factors was not met, it represented a barrier. Other facilitators identified were (4) Attachment to one's home, (5) Feeling of commitment toward a loved one, (6) Having the possibility of going through a transitional phase, (7) United front between the patient and the family caregiver towards a return home. Additional barriers to returning home included: (8) Incongruent perspectives, and (9) Unclear knowledge about available health and other services at home. CONCLUSION The results of this study could be translated into a practical tool to guide patients, families and professionals in the decision about returning home or exploring an alternative option after inpatient rehabilitation for TBI in older adults.IMPLICATIONS FOR REHABILITATIONWhen orienting an older patient home or to an alternative living environment after a traumatic brain injury (TBI), the perspective of rehabilitation professionals can differ from that of patients and caregivers.Professionals tend to emphasize security, whereas patients and caregivers' focus on the well-being associated with home and on the importance of being with their loved one.Integrating the views, values and wishes of older patients with TBI and their caregivers will support a shared decision-making approach for orientation after rehabilitation.

Abstract
BACKGROUND Despite equalized acute care in trauma, disparities exist in the long-term outcomes of trauma survivors. Prior studies have revealed insurance status plays a role in the discharge destination of blunt trauma survivors. This is yet to be described in patients with penetrating traumatic injury. METHODS A retrospective chart review from 2009 to 2019 from an urban Level 1 trauma center identified adult patients who survived penetrating trauma to discharge. Patients were categorized by insurance status. Patient demographics, discharge destination, and hospital length of stay (LOS) were analyzed using the t-test and ANOVA. RESULTS 1806 patients were identified with 1410 survivors to hospital discharge. Among the survivors, 26.8% were uninsured, 13.1% were privately insured, and 60.0% had Medicare/Medicaid. The uninsured patients were significantly less likely to be discharged to a rehabilitation facility or skilled nursing facility (OR = .49, 95% CI .35-.71) compared to the insured patients. Uninsured survivors had shorter LOS compared to the other groups (5.8 vs. 7.3, P < .01.) Severity of injury did not significantly influence the discharge destination or LOS between the groups. CONCLUSION Despite recent health care reform, many trauma patients remain uninsured. Our study shows that uninsured penetrating trauma survivors are less likely to be discharged to rehabilitation and skilled nursing facilities. This may contribute to uninsured trauma survivors not receiving appropriate post-traumatic care and could lead to the accrual of undue disability, long-term complications, and increased societal burdens.

Abstract
OBJECTIVES The objectives of this study were to identify functional limitations in patients with coronavirus 2019 (COVID-19) admitted to acute care hospitals; to evaluate functional limitations by demographic, medical, and encounter characteristics; and to examine functional limitations in relation to discharge destination. DESIGN and Setting:This is a cross-sectional, retrospective study of adult patients with COVID-19 who were discharged from 2 different types of hospitals (academic medical center and a community hospital) within 1 health care system from January 1 to April 30, 2020. PARTICIPANTS Patients were identified from the Cedars-Sinai COVID-19 data registry who had a new-onset positive test for severe acute respiratory syndrome coronavirus 2. A total of 273 patients were identified, which included 230 patients who were discharged alive and 43 patients who died and were excluded from the study sample. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Functional limitations in patients with COVID-19 in acute care hospitals and the predictors for discharge disposition. RESULTS A total of 230 records were analyzed including demographic, encounter, medical, and functional variables. In a propensity score-matched cohort based on age and comorbidity, 88.2% had functional physical health deficits, 72.5% had functional mental health deficits, and 17.6% experienced sensory deficits. In the matched cohort, individuals discharged to an institution experienced greater physical (62.7% vs 25.5%, P<.001) and mental health (49.0% vs 23.5%, P=.006) deficits than patients discharged home. Marital status (odds ratio, 3.17; P=.011) and physical function deficits (odds ratio, 3.63; P=.025) were associated with an increase odds ratio of discharge to an institution. CONCLUSIONS This research highlights that functional status is a strong predictor for discharge destination to an institution for patients with COVID-19. Patients who were older, in the acute care hospital longer, and with comorbidities were more likely to be discharged to an institution. Rehabilitation is a significant aspect of the health care system for these vulnerable patients. The challenges of adjusting the role of rehabilitation providers and systems during the pandemic needs further exploration. Moreover, additional research is needed to look more closely at the many facets and timing of functional status needs, to shed light in use of interdisciplinary rehabilitation services, and to guide providers and health care systems in facilitating optimal recovery and patient outcomes.
