ObjectiveTo determine the effectiveness of booster vaccinations on the risk of hospitalization with coronavirus disease 2019 (COVID-19) and how it varies by enrollee characteristics and interval from the initial vaccination to receipt of a booster.Patients and MethodsThis cohort study used 100% Medicare claims from January 1, 2020, through December 31, 2021, and matched 3,940,475 individuals who received boosters to 3,940,475 controls based on week and type of original COVID-19 vaccine and demographic and clinical characteristics. We compared the association of booster vs no booster with COVID-19 hospitalization using Cox proportional hazards regression models controlling for patient characteristics. We also determined the association of time from original vaccine to booster with COVID-19 hospitalization.ResultsOver a maximum of 130 days of follow-up, boosted enrollees had 8.20 (95% CI, 7.81 to 8.60) COVID-19 hospitalizations per million days vs 43.70 (95% CI, 42.79 to 44.64) for controls (81% effectiveness). Effectiveness varied by race, prior hospitalizations, and certain comorbidities, for example, leukemia/lymphoma (53% effectiveness), autoimmune disease (73%), and dementia (73%). Boosters received between 6 and 9 months after original vaccination varied between 81% and 85% effectiveness, while boosters received at 5 to 6 months (62%) or less than 5 months (58%) were less effective.ConclusionBoosters are highly effective in the Medicare population. Approximately 69,225 hospitalizations would be prevented by boosters in the 15 million individuals aged 65 years or older currently not boosted in a period similar to the September 2020 through January 2021 period studied. Boosters provided the greatest benefits if they were received between 6 and 9 months following original vaccinations. However, boosters were associated with substantial decreases in COVID-19 hospitalizations in all categories of enrollees. 相似文献

ObjectiveTo explore the association between demographic factors and functional performance measures of patients with acute stroke in an inpatient rehabilitation facility (IRF) and falls during the IRF stay and to quantify the diagnostic accuracy of functional outcome measures in identifying fallers.DesignRetrospective cohort study.SettingInpatient rehabilitation facility.ParticipantsIndividuals with acute stroke admitted to hospital-based IRF (N=139).InterventionsNot applicable.Main Outcome MeasuresOdds ratios were used to examine the relationship between fall frequency and functional outcome measures (National Institute of Stroke Scale, neglect [Item #11], Berg Balance Scale, Stroke Rehabilitation Assessment of Movement mobility and Stroke Rehabilitation Assessment of Movement lower extremity subscales [STREAM-LE], Montreal Cognitive Assessment, Dynamic Gait Index, and Stroke Impact Scale). Receiver operator characteristic analysis with area under the curve, sensitivity, specificity, and diagnostic odds ratio were used to assess the diagnostic accuracy of each functional outcome measure to distinguish patients who fell vs those who did not fall in the IRF.ResultsA total of 23 patients (16.2%) fell during the IRF hospitalization. Patients who did and did not fall did not differ in terms of age, sex, stroke type, or stroke location. Only the STREAM-LE was associated with falls (odds ratio, 0.93; 95% CI, 0.86-0.99). Area under the curve was 0.67 (95% CI, 0.51-0.82). With a positivity cutoff point of 12, sensitivity and specificity were 73.3% (95% CI, 54.6%-92.2%) and 50.0% (95% CI, 39.9%-59.2%), respectively. The diagnostic odds ratio was 3.4.ConclusionsThe STREAM-LE score at admission to IRF may identify patients with acute stroke who are more likely to fall during their stay. However, the search for measures with greater diagnostic accuracy should continue. 相似文献

ObjectiveTo determine the prevalence and risk factors for inappropriate discharge on proton pump inhibitor (PPI) therapy started in the intensive care unit (ICU) for stress ulcer prophylaxis.Patients and MethodsThis was a retrospective cohort study of adults initiated on treatment with a PPI in any of 9 affiliated ICUs from January 1, 2014, to December 31, 2018. Patients were excluded if they had an appropriate long-term PPI indication. Logistic regression modeling was used to identify characteristics associated with discharge on treatment with an inappropriate PPI.ResultsOf 24,751 patients admitted to an ICU, 4127 were initiated on treatment with a new PPI, with 2467 (60%) lacking a long-term PPI indication. Of these 2467, a total of 1122 (45%) were continued on PPI therapy after transfer to the floor and 668 (27%) were discharged on PPI therapy. On multivariable analysis, risk factors for inappropriate discharge on PPI therapy included having an upper endoscopy (adjusted odds ratio [aOR], 1.70; 95% CI, 1.08-2.66), admission to the surgical compared with medical ICU (aOR, 2.03; 95% CI, 1.32-3.10), and discharge to a nursing home or rehabilitation facility (aOR, 1.43; 95% CI, 1.04-1.96; and aOR, 2.29; 95% CI, 1.62-3.24, respectively).ConclusionAmong patients started on treatment with a PPI in the ICU without an indication for outpatient PPI use, 27% (668 of 2467) were nonetheless discharged on PPI therapy. Medically complex and surgical ICU patients are at increased risk for receiving PPIs without appropriate documented indications, and careful review of medication lists at discharge should occur in these high-risk groups. 相似文献

ObjectiveTo evaluate the effect of providing a greater percentage of therapy as contextualized treatment on acute traumatic brain injury (TBI) rehabilitation outcomes.DesignPropensity score methods are applied to the TBI Practice-Based Evidence (TBI-PBE) database, a database consisting of multi-site, prospective, longitudinal observational data.SettingAcute inpatient rehabilitation.ParticipantsPatients enrolled in the TBI-PBE study (N=1843), aged 14 years or older, who sustained a severe, moderate, or complicated mild TBI, received their first inpatient rehabilitation facility admission in the US, and consented to follow-up 3 and 9 months post discharge from inpatient rehabilitation.InterventionsNot applicable.Main Outcome MeasuresParticipation Assessment with Recombined Tools-Objective (PART-O)-17, FIM Motor and Cognitive scores, Satisfaction with Life Scale, and Patient Health Questionnaire-9.ResultsIncreasing the percentage of contextualized treatment during inpatient TBI rehabilitation leads to better outcomes, specifically in regard to community participation.ConclusionsIncreasing the proportion of treatment provided in the context of real-life activities appears to have a beneficial effect on outcome. Although the effect sizes are small, the results are consistent with other studies supporting functional-based interventions effecting better outcomes. Furthermore, any positive findings, regardless of size or strength, are endorsed as important by consumers (survivors of TBI). While the findings do not imply that decontextualized treatment should not be used, when the therapy goal can be addressed with either approach, the findings suggest that better outcomes may result if the contextualized approach is used. 相似文献

ObjectiveTo evaluate the association of baseline and postinfusion patient characteristics with acute kidney injury (AKI) in the month after chimeric antigen receptor T-cell (CAR-T) therapy.MethodsWe retrospectively reviewed records of 83 patients with non-Hodgkin lymphoma undergoing CAR-T therapy (axicabtagene ciloleucel) between June 2016 and November 2020. Patients were followed up to 1 month after treatment. Post–CAR-T AKI was defined as a more than 1.5-fold increase in serum creatinine concentration from baseline (on the day of CAR-T infusion) at any time up to 1 month after CAR-T therapy.ResultsOf 83 patients, 14 (17%) developed AKI during follow-up. At 1 month after CAR-T infusion, 10 of 14 (71%) AKI events had resolved. Lower baseline estimated glomerular filtration rate, use of intravenous contrast material, tumor lysis prophylaxis, higher peak uric acid and creatine kinase levels during follow-up, and change in lactate dehydrogenase from baseline to peak level within 1 month after initiation of CAR-T therapy were significantly associated with AKI incidence during follow-up. Incidence of AKI was also higher in patients who received higher doses of corticosteroids and tocilizumab.ConclusionAcute kidney injury occurred in approximately 1 in 6 patients who received axicabtagene ciloleucel for non-Hodgkin lymphoma. Patients with high tumor burden receiving higher total doses of corticosteroids or tocilizumab should be closely monitored for development of AKI. Lower baseline kidney function at CAR-T initiation, exposure to contrast material, and progressive increase in levels of tumor lysis markers (uric acid, lactate dehydrogenase, creatine kinase) after CAR-T infusion may predict risk of AKI during the 1 month after infusion. 相似文献

ObjectiveTo study the patient profiles and the prognostic impact of type 2 myocardial infarction (MI) on outcomes of acute ischemic stroke (AIS).MethodsThe National Readmission Database 2018 was queried for patients with primary AIS hospitalizations with and without type 2 MI. Baseline characteristics, inpatient outcomes, and 30-day all-cause readmissions between cohorts were compared.ResultsOf 587,550 AIS hospitalizations included in the study, 4182 (0.71%) had type 2 MI. Patients with type 2 MI were older (73.6 years vs 70.1 years; P<.001) and more likely to be female (52% vs 49.7%; P<.001), and they had a higher prevalence of heart failure (32.6% vs 15.5%; P<.001), atrial fibrillation (38.5% vs 24.2%; P<.001), prior MI (8.8% vs 7.7%; P<.001), valvular heart disease (17% vs 9.8%; P<.001), peripheral vascular disease (12.2% vs 9.2%; P<.001), and chronic kidney disease (24.4% vs 16.7%; P<.001). Compared with patients without type 2 MI, AIS patients with type 2 MI had significantly higher in-hospital mortality (adjusted odds ratio [aOR], 1.96; 95% CI, 1.65 to 2.32), poor functional outcome (aOR, 1.80; 95% CI, 1.62 to 2.00), more hospital costs (adjusted parameter estimate, $5618; 95% CI, $4480 to $6755), higher rate of discharge to a facility (aOR, 1.70; 95% CI, 1.52 to 1.90), increased length of stay (adjusted parameter estimate, 2.22; 95% CI, 1.72 to 2.72), and higher rate of 30-day all-cause readmissions (aOR, 1.38; 95% CI, 1.18 to 1.60).ConclusionType 2 MI in patients hospitalized with AIS is associated with poor prognosis and higher resource utilization. 相似文献

ObjectiveTo identify determinants of discharge disposition from acute care among survivors of hypoxic-ischemic brain injury (HIBI), stratified by sex.DesignPopulation-based retrospective cohort study using provincial data in Ontario, Canada. The determinants were grouped into predisposing, need, and enabling factors using the Anderson Behavioral Model.SettingAcute care.ParticipantsSurvivors of HIBI aged ≥20 years at the time of hospitalization and discharged alive from acute care between April 1, 2002, and March 31, 2017. There were 7492 patients with HIBI, of whom 28% (N=2077) survived their acute care episode.InterventionsNot applicable.Main Outcome MeasuresDischarge disposition from acute care, categorized as complex continuing care (CCC), long-term care (LTC), inpatient rehabilitation (IR), home with support, home without support, and transferred to another acute care.ResultsThe discharge dispositions for the 2077 survivors were IR 23.4% (n=487), CCC 19.5% (n=404), LTC 6.2% (n=128), home without support 31.2% (n=647), home with support 15.1% (n=314), and other 4.6%. Multinomial multivariable logistic regression analysis using home without support as the reference category revealed that female patients were significantly more likely than male patients to be discharged to LTC/CCC. Those who were older, were frail, and had longer stay in acute care or special care unit (SCU) were more likely to be discharged to LTC/CCC. The only significant determinant for IR was longer stay in acute care. Survivors with cardiac-related injury were less likely to be discharged to LTC/CCC. Income was a significant factor for male patients but not for female patients in the sex-stratified analysis. The following variables were investigated but were not significant determinants in this study: need factors (comorbidity score, prior psychiatric disorders, health care utilization) and enabling factors (income quintile, rural area of residence).ConclusionsPredisposing (age, sex) and need factors (frailty, acute care days, SCU days, type of injury) were significant determinants of discharge disposition from acute care after HIBI. In spite of a system with universal coverage, sex differences were found, with more female patients being discharged to CCC/LTC rather than IR, controlling for age and other confounders. These findings should be considered in appropriate discharge planning from acute care for survivors of HIBI. 相似文献

ObjectiveTo evaluate the effect of family attendance at inpatient rehabilitation therapy sessions on traumatic brain injury (TBI) patient outcomes at discharge and up to 9 months postdischarge.DesignPropensity score methods are applied to the TBI Practice-Based Evidence database, a database consisting of multisite, prospective, longitudinal, and observational data.SettingNine inpatient rehabilitation centers in the United States.ParticipantsPatients (N=1835) admitted for first inpatient rehabilitation after an index TBI.InterventionFamily attendance during therapy sessions.Main Outcome MeasuresParticipation Assessment for Recombined Tools-Objective-17 (Total scores and subdomain scores of Productivity, Out and About, and Social Relations), Functional Independence Measure, Satisfaction with Life Scale, and Patient Health Questionnaire-9.ResultsParticipants whose families were in attendance for at least 10% of the treatment time were more out and about in their communities at 3 and 9 months postdischarge than participants whose families attended treatment less than 10% of the time. Although findings varied by propensity score method, improved functional independence in the cognitive area at 9 months was also associated with increased family attendance.ConclusionsFamily involvement during inpatient rehabilitation may improve community participation and cognitive functioning up to 9 months after discharge. Rehabilitation teams should engage patients’ families in the rehabilitation process to maximize outcomes. 相似文献

ObjectiveTo investigate whether crossed cerebellar diaschisis (CCD) is associated with functional outcome in the subacute rehabilitation phase of stroke.DesignRetrospective case-control study.SettingHospital-based cohort.ParticipantsThe study enrolled participants who underwent brain single-photon emission computed tomography (N=48). Patients with CCD were identified (n=24). Twenty-four controls were selected for each case-patient by matching age, stroke type (ischemic or hemorrhagic), lesion laterality, and lesion location.InterventionNot applicable.Main Outcome MeasuresThe functional ambulation category (FAC), modified Barthel Index (MBI), and Mini-Mental State Examination (MMSE) were administered at the initial (initiation of rehabilitation therapy) and the follow-up (4wk after rehabilitation therapy) assessments.ResultsThe CCD group had lower MMSE, FAC, MBI, and MMSE scores at the initial assessment (P=.032, .016, and .001, respectively) and lower FAC and MBI scores at the follow-up assessment, than the non-CCD group (P=.001 and .036, respectively). Although CCD was not associated with cognitive impairment, nonambulatory status, and dependent activities of daily living (ADL) at the initial assessment (P=.538, .083, and >.99, respectively), the CCD group had a higher risk of cognitive impairment (adjusted odds ratio [aOR]=4.044; 95% confidence interval [CI], 1.071-15.270; P=.039), nonambulatory status (aOR=7.000; 95% CI, 1.641-29.854; P=.009) and dependent ADL (aOR=13.500; 95% CI, 1.535-118.692; P=.019) at the follow-up assessment.ConclusionsCCD is associated with severe functional impairment and may have an adverse effect on functional outcomes related to cognition, ambulatory function, and ADL during the subacute rehabilitation phase of stroke. This suggests that CCD may be a valuable predictor of functional outcome in the subacute rehabilitation phase of stroke. 相似文献

PurposeThe management of acute stroke is challenging. The aim of this meta-analysis was to determine the efficacy and tolerability of edaravone, with or without thrombolytic therapy, in the treatment of patients with acute ischemic stroke.MethodsThe PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials (RCTs) and cohort studies. Mean differences (MD), risk ratios (RR), 95% confidence interval (CI), and heterogeneity were calculated.FindingsTotals of nine RCTs and four cohort studies were included, for a total of 2102 patients. In patients with acute ischemic stroke, edaravone monotherapy was associated with significantly improved Barthel Index of functioning in activities for daily living (MD, 23.95; 95% CI, 18.48 to 29.41; P < 0.001) and neurologic deficit, (as measured using the National Institutes of Health Stroke Scale score) (MD = –3.49; 95% CI, –5.76 to 1.22; P = 0.003), on short-term follow-up. However, edaravone was not associated with an improved rate of death or disability (RR = 0.75; 95% CI, 0.45 to 1.23; P = 0.25) on long-term follow-up.When plus to thrombolytic therapy, edaravone was associated with significant improvements in recanalization rate (RR = 1.71; 95% CI, 1.05 to 2.77; P = 0.03) and neurologic deficit (MD = 3.97; 95% CI, 5.14 to 2.79; P < 0.001), without an increase in the prevalence of bleeding events (RR = 1.11; 95% CI, 0.76 to 1.62; P = 0.59). However, edaravone did not have a significant effect on death or disability (RR = 0.85; 95% CI, 0.69 to 1.04; P = 0.12).ImplicationsBased on the findings from the present meta-analysis, edaravone was an effective and well-tolerated neuroprotective agent in these patients with ischemic stroke. With the use of edaravone, activities of daily living and neurologic deficits, along with recanalization rates, were improved on short-term follow-up, but the long-term effects still need confirmation in larger-scale clinical trials. 相似文献

ObjectiveTo determine whether biological effective dose (BED) was predictive of obliteration after stereotactic radiosurgery (SRS) for cerebral arteriovenous malformations (AVMs).Patients and MethodsWe studied patients undergoing single-session AVM SRS between January 1, 1990, and December 31, 2014, with at least 2 years of imaging follow-up. Excluded were patients with syndromic AVM, previous SRS or embolization, and patients treated with volume-staged SRS. Biological effective dose was calculated using a mono-exponential model described by Jones and Hopewell. The primary outcome was likelihood of total obliteration defined by digital subtraction angiography or magnetic resonance imaging (MRI). Variables were analyzed as continuous and dichotomous variables based on the maximum value of (sensitivity–[1–specificity]).ResultsThis study included 352 patients (360 AVM, median follow-up, 5.9 years). The median margin dose prescribed was 18.75 Gy (interquartile range [IQR]: 18 to 20 Gy). Two hundred fifty-nine patients (71.9%) had obliteration shown by angiography (n=176) or MRI (n=83) at a median of 36 months after SRS (IQR: 26 to 44 months). Higher BED was associated with increased likelihood of obliteration in univariate Cox regression analyses, when treated as either a dichotomous (≥133 Gy; hazard ratio [HR],1.52; 95% confidence interval [CI], 1.19 to 1.95; P<.001) or continuous variable (HR, 1.00, 95% CI, 1.0002 to 1.005; P=.04). In multivariable analyses including dichotomized BED and location, BED remained associated with obliteration (P=.001).ConclusionBiological effective dose ≥133 Gy was predictive of AVM obliteration after single-session SRS within the prescribed margin dose range 15 to 25 Gy. Further study is warranted to determine whether BED optimization should be considered as well as treatment dose for AVM SRS planning. 相似文献

Oral anticoagulation is the dominant strategy for stroke prevention in patients with nonvalvular atrial fibrillation. However, lifelong oral anticoagulation is associated with major issues including inappropriate dosing, nonadherence, and adverse effects. Therefore, efforts have been made to develop site-specific therapy aimed to occlude the left atrial appendage, the anatomical site accountable for more than 90% of nonvalvular atrial fibrillation–related ischemic strokes. This review focuses on the growing literature to put into perspective the risk-balance ratio of left atrial appendage occlusion. 相似文献

ObjectiveTo investigate the effects of perturbation-based pinch task training on the sensorimotor performance of the upper extremities of patients with chronic stroke via a novel vibrotactile therapy system.DesignA single-blinded randomized controlled trial.SettingA university hospital.ParticipantsPatients with chronic stroke (N=19) randomly assigned into either an experimental group or a control group completed the study.InterventionsIn addition to 10 minutes of traditional sensorimotor facilitation, each participant in the experimental group received 20 minutes of perturbation-based pinch task training in each treatment session, and the controls received 20 minutes of task-specific motor training twice a week for 6 weeks.Main Outcome MeasuresThe scores for the primary outcome, Semmes-Weinstein monofilament (SWM), and those for the secondary outcomes, Fugl-Meyer Assessment (FMA), amount of use, quality of movement (QOM) on the Motor Activity Log (MAL) scale, and box and block test (BBT), were recorded. All outcome measures were recorded at pretreatment, post treatment, and 12-week follow-up.ResultsThere were statistically significant between-group differences in the training-induced improvements revealed in the SWM results (P=.04) immediately after training and in the BBT results (P=.05) at the 12-week follow-up. The changes in muscle tone and in the QOM, SWM, and BBT scores indicated statistically significant improvements after 12 sessions of treatment for the experimental group. For the control group, a significant statistical improvement was found in the wrist (P<.001) and coordination (P=.01) component of the FMA score.ConclusionsThis study indicated that the perturbation-based pinch task training has beneficial effects on sensory restoration of the affected thumb in patients with chronic stroke. 相似文献

Acute flaccid myelitis (AFM) is characterized by flaccid paralysis of one or more limbs, often following a viral illness, with magnetic resonance imaging findings consistent with inflammation of the spinal cord gray matter. It is unclear whether all patients with AFM will have full recovery of neurologic function. Since 2014, there have been several clusters of AFM in the United States, with a 3-fold increase in reported AFM cases recorded in 2018 compared with the previous year. Epidemiological evidence supports a temporal association between respiratory enteroviral illness, particularly with enteroviruses D68 and A71, and clustering of AFM cases. However, causality has yet to be established. Treatment of AFM is primarily supportive. Adjunctive therapies such as intravenous immunoglobulin, corticosteroids, plasmapheresis, and fluoxetine have not been found to improve long-term outcomes. Further research is urgently needed to characterize and optimize management of this emerging, yet poorly understood, condition. 相似文献

ObjectivesTo examine the association of patient and direct-care staff beliefs about patients’ capability to increase independence with activities of daily living (ADL) and the probability of successful discharge to the community after a skilled nursing facility (SNF) stay.DesignRetrospective cohort study of SNF patients using 100% Medicare inpatient claims and Minimum Data Set resident assessment data. Linear probability models were used to estimate the probability of successful discharge based on patient and staff beliefs about the patient’s ability to improve in function, as well as patient and staff beliefs together. Estimates were adjusted for demographics, health status, functional characteristics, and SNF fixed effects.ParticipantsFee-for-service Medicare beneficiaries (N=526,432) aged 66 years or older who were discharged to an SNF after hospitalization for stroke, hip fracture, or traumatic brain injury.InterventionsNot applicable.Main Outcome MeasuresSuccessful community discharge (discharged alive within 90d of SNF admission and remaining in the community for ≥30d without dying or health care facility readmission).ResultsPatients with positive beliefs about their capability to increase independence with ADLs had a higher adjusted probability of successful discharge than patients with negative beliefs (positive, 63.8%; negative, 57.8%; difference, 6.0%, 95% confidence interval [CI], 5.4-6.6). This remained true regardless of staff beliefs, but the difference in successful discharge probability between patients with positive and negative beliefs was larger when staff had positive beliefs. Conversely, the association between staff beliefs and successful discharge varied based on patient beliefs. If patients had positive beliefs, the difference in the probability of successful discharge between positive and negative staff beliefs was 2.5% (95% CI, 1.0-4.0). If patients had negative beliefs, the difference between positive and negative staff beliefs was –4.6% (95% CI, –6.0 to –3.2).ConclusionsPatients’ beliefs have a significant association with the probability of successful discharge. Understanding patients’ beliefs is critical to appropriate goal-setting, discharge planning, and quality SNF care. 相似文献
