RESUMEN

BACKGROUND: Obesity is associated with poor outcomes for patients with rheumatoid arthritis (RA). Effective weight management is imperative. Although traditional lifestyle behavioral weight loss programs have demonstrated efficacy for reducing weight, these interventions do not meet the pain-related weight loss challenges of RA patients with obesity. OBJECTIVE: A 12-session group program (90 minutes per session) was developed integrating pain coping skills training into a lifestyle behavioral weight loss intervention. In addition to the weekly group sessions, participants engaged in supervised exercise sessions 3 times per week. METHODS: Through a small, pilot randomized trial, 50 participants were randomized to receive the intervention (n = 29) or standard care of RA (n = 21). Feasibility data (i.e., accrual, attrition, adherence) was examined using descriptive statistics (e.g., percent). We examined patterns of change in study outcomes from baseline to follow-up separately for the intervention and standard care arms using descriptive statistics and paired t tests. Effect sizes are also presented. RESULTS: Of those randomized to the intervention group,79.3% initiated treatment, with participants attending 74.3% of group skills sessions and 64.2% of exercise sessions. Intervention participants evidenced reductions in weight (mean, -2.28 kg) and waist circumference (mean, -4.76 cm) and improvements in physical functioning, eating behaviors, pain, and self-efficacy for weight control. CONCLUSIONS: Findings suggest that incorporating a combined pain coping skills training and behavioral weight loss intervention into medical management of RA may improve outcomes. Study accrual and attrition, as well as intervention adherence, will inform future, larger randomized efficacy trials of the intervention.Retrospectively registered: January 29, 2020, NCT04246827.

RESUMEN

BACKGROUND: Clinically vulnerable individuals have been advised to shield themselves during the COVID-19 epidemic. The objectives of this study were to investigate (1) the rate ratio of severe COVID-19 associated with eligibility for the shielding programme in Scotland across the first and second waves of the epidemic and (2) the relation of severe COVID-19 to transmission-related factors in those in shielding and the general population. METHODS: In a matched case-control design, all 178,578 diagnosed cases of COVID-19 in Scotland from 1 March 2020 to 18 February 2021 were matched for age, sex and primary care practice to 1,744,283 controls from the general population. This dataset (REACT-SCOT) was linked to the list of 212,702 individuals identified as eligible for shielding. Severe COVID-19 was defined as cases that entered critical care or were fatal. Rate ratios were estimated by conditional logistic regression. RESULTS: With those without risk conditions as reference category, the univariate rate ratio for severe COVID-19 was 3.21 (95% CI 3.01 to 3.41) in those with moderate risk conditions and 6.3 (95% CI 5.8 to 6.8) in those eligible for shielding. The highest rate was in solid organ transplant recipients: rate ratio 13.4 (95% CI 9.6 to 18.8). Risk of severe COVID-19 increased with the number of adults but decreased with the number of school-age children in the household. Severe COVID-19 was strongly associated with recent exposure to hospital (defined as 5 to 14 days before presentation date): rate ratio 12.3 (95% CI 11.5 to 13.2) overall. The population attributable risk fraction for recent exposure to hospital peaked at 50% in May 2020 and again at 65% in December 2020. CONCLUSIONS: The effectiveness of shielding vulnerable individuals was limited by the inability to control transmission in hospital and from other adults in the household. Mitigating the impact of the epidemic requires control of nosocomial transmission.

RESUMEN

Clinical trials provide the foundational evidence that guide many patient-facing decisions; however, the therapeutic effect and safety of an intervention is best evaluated when compared to a control group. We used ClinicalTrials.gov to describe the proportion of registered Phase III and IV cardiovascular clinical trials that contain a control group from 2009 through 2019. Of 1,677 registered Phase III and IV cardiovascular clinical trials, 81.2% contain a control group, and the annual prevalence remained unchanged between 2009 and 2019.

RESUMEN

BACKGROUND: COVID-19 deaths are commoner among care-home residents, but the mortality burden has not been quantified. METHODS: Care-home residency was identified via a national primary care registration database linked to mortality data. Life expectancy was estimated using Makeham-Gompertz models to (i) describe yearly life expectancy from November 2015 to October 2020 (ii) compare life expectancy (during 2016-18) between care-home residents and the wider population and (iii) apply care-home life expectancy estimates to COVID-19 death counts to estimate years of life lost (YLL). RESULTS: Among care-home residents, life expectancy in 2015/16 to 2019/20 ranged from 2.7 to 2.3 years for women and 2.3 to 1.8 years for men. Age-sex-specific life expectancy in 2016-18 in care-home residents was lower than in the Scottish population (10 and 2.5 years in those aged 70 and 90, respectively). Applying care home-specific life expectancies to COVID-19 deaths yield mean YLLs for care-home residents of 2.6 and 2.2 for women and men, respectively. In total YLL care-home residents have lost 3,560 years in women and 2,046 years in men. Approximately half of deaths and a quarter of YLL attributed to COVID-19 were accounted for by the 5% of over-70s who were care-home residents. CONCLUSION: COVID-19 infection has led to the loss of substantial years of life in care-home residents aged 70 years and over in Scotland. Prioritising the 5% of older adults who are care-home residents for vaccination is justified not only in terms of total deaths, but also in terms of YLL.

RESUMEN

BACKGROUND: Converging literatures suggest that deep brain stimulation (DBS) in Parkinson's disease affects multiple circuit mechanisms. One proposed mechanism is the normalization of primary motor cortex (M1) pathophysiology via effects on the hyperdirect pathway. OBJECTIVES: We hypothesized that DBS would reduce the current intensity necessary to modulate motor-evoked potentials from focally applied direct cortical stimulation (DCS). METHODS: Intraoperative subthalamic DBS, DCS, and preoperative diffusion tensor imaging data were acquired in 8 patients with Parkinson's disease. RESULTS: In 7 of 8 patients, DBS significantly reduced the M1 DCS current intensity required to elicit motor-evoked potentials. This neuromodulation was specific to select DBS bipolar configurations. In addition, the volume of activated tissue models of these configurations were significantly associated with overlap of the hyperdirect pathway. CONCLUSIONS: DBS reduces the current necessary to elicit a motor-evoked potential using DCS. This supports a circuit mechanism of DBS effectiveness, potentially involving the hyperdirect pathway that speculatively may underlie reductions in hypokinetic abnormalities in Parkinson's disease. © 2020 International Parkinson and Movement Disorder Society.

RESUMEN

BACKGROUND: Obese rheumatoid arthritis (RA) patients have higher levels of pain, disability, and disease activity than do nonobese patients with RA. Patients' health-related thoughts about arthritis and weight may be important to consider in obese patients with RA who face the dual challenge of managing RA and weight. OBJECTIVES: The objective of this study was to examine the relationships of pain catastrophizing, self-efficacy (ie, confidence) for arthritis management and self-efficacy for weight management to important outcomes in obese patients with RA. We expected that after controlling for demographic and medical variables, higher levels of pain catastrophizing and lower levels of confidence would account for significant and unique variance in pain, physical functioning, and overeating. METHODS: Participants had a diagnosis of RA and a body mass index of 28 kg/m or greater and completed self-report questionnaires assessing pain, physical functioning, overeating, pain catastrophizing, self-efficacy for arthritis management, self-efficacy for weight management, and a 6-minute walk test. RESULTS: Pain catastrophizing, self-efficacy for arthritis, and self-efficacy for weight management were significantly and uniquely related to RA-related outcomes. Pain catastrophizing was a significant independent predictor of pain severity (ß = 0.38); self-efficacy for arthritis was a significant independent predictor of self-report physical functioning (ß = -0.37) and the 6-minute walk performance (ß = 0.44), and self-efficacy for weight management was a significant independent predictor of overeating (ß = -0.58). CONCLUSIONS: Pain catastrophizing, self-efficacy for arthritis, and self-efficacy for weight management each contributed uniquely to relate to key outcomes in obese patients with RA. Clinicians should consider assessment of thought processes when assessing and intervening with patients who face dual health challenges; unique intervention approaches may be needed for addressing the challenges of arthritis and weight.

RESUMEN

Background: Postoperative hyponatremia is a known complication of intracranial surgery, which can present with depressed mental status. Hyponatremia resulting in focal neurologic deficits is less frequently described. Case Description: We describe a patient who, after a bifrontal craniotomy for olfactory groove meningioma, developed acute hyponatremia overnight with a decline in mental status from Glasgow coma scale (GCS) score 15 to GCS 7 and a unilateral fixed dilated pupil. Head computed tomography showed expected postoperative changes without new acute or localizing findings, such as unilateral uncal herniation. The patient's mental status and pupil immediately improved with the administration of mannitol; however, there was a subsequent decline in mental status with a preserved pupil later that morning. Hypertonic saline reversed the neurologic change, and the patient was eventually discharged without a neurologic deficit. Focal neurologic deficits need not always arise following a craniotomy from a postoperative hematoma, stroke, or other finding with radiographic correlate. Conclusion: Post-craniotomy hyponatremia should now be seen as a postoperative complication that can result in both a general neurologic decline in mental status, as well as with focal neurologic signs such as a fixed, dilated pupil, which can be reversed with hyperosmolar therapy and correction of the hyponatremia.

RESUMEN

OBJECTIVE: The purpose of this study is to use feedback from student evaluations of teaching (SETs) to define and describe themes associated with perceived teaching effectiveness. METHODS: We retrospectively analyzed SETs for instructors in required didactic courses from one academic year using qualitative content analysis. The analysis included student responses to the following questions: "Describe the strongest aspect of the instructor's teaching." and "What could the instructor do to improve his/her teaching effectiveness?" RESULTS: Five themes were developed from 4683 coded segments and are described with example quotations. These themes included clarity of instruction and learning activities, alignment of learning and assessment activities, examples that offer practice or demonstrate relevance, engaging learning environment, and concern for student learning and success. Aspects of each theme are described with example coded segments. CONCLUSION: These themes and supportive quotes offer a deeper understanding of the student perspective on similar ideas that are present throughout the teaching and learning literature and represent broad aspects of teaching, such as material design, in-class practices, and interpersonal characteristics. These themes can provide guidance for specific domains of faculty development in teaching.

RESUMEN

The historically African-American Rogers-Eubanks community straddles unincorporated boundaries of two municipalities in Orange County, North Carolina, and predates a regional landfill sited along its border in 1972. Community members from the Rogers-Eubanks Neighborhood Association (RENA), concerned about deterioration of private wells and septic systems and a lack of public drinking water and sewer services, implemented a community-driven research partnership with university scientists and community-based organizations to investigate water and sewer infrastructure disparities and the safety of drinking and surface water supplies. RENA drafted memoranda of agreement with partners and trained community monitors to collect data (inventory households, map water and sewer infrastructure, administer household water and sewer infrastructure surveys, and collect drinking and surface water samples). Respondents to the surveys reported pervasive signs of well vulnerability (100%) and septic system failure (68%). Each 100-m increase in distance from the landfill was associated with a 600 most probable number/100 mL decrease in enterococci concentrations in surface water (95% confidence interval = -1106, -93). Pervasive private household water and sewer infrastructure failures and poor water quality were identified in this community bordering a regional landfill, providing evidence of a need for improved water and sanitation services.

RESUMEN

Pharmacy faculty have begun to adopt therapy-speak, which are common words and phrases derived from mental health services, more frequently in both informal modes of communication as well as in scholarly and creative efforts. In this Commentary, we consider the use of this trendy, idiomatic language in scholarly writing and characterize potential problems with its clear and lasting interpretation. Conversely, we also examine how contemporary language can be used to enhance scholarly writing by engaging members of the Academy with an interesting writing style. Finally, we challenge pharmacy faculty to carefully consider how and when such language can be used to communicate in a clear and straightforward style that creates interest among readers.

RESUMEN

Objective. To provide a review of best practices for diversity, equity, and inclusion (DEI) committees at United States colleges of pharmacy.Findings. In colleges of pharmacy, DEI committees can play a crucial role in promoting a culture change to ensure pharmacy graduates are equipped to provide equitable and representative care for the patients they serve. There is limited literature available on DEI committee composition, roles, and responsibilities, and their place within a college of pharmacy's organizational structure. A commitment to DEI should be part of the college's strategic plan and embedded and supported at all levels of the college and university to ensure success of DEI-related strategic initiatives. For a DEI committee to be effective, its composition should be intentional to include change agents, campus leaders, and members who are passionate and knowledgeable to execute the DEI goals. For sustainable change, involvement of the entire learning community and an organizational culture change is also important. Thus, DEI committees need to establish active bidirectional collaborations and communication with all key committees, offices, community leaders, and alumni to implement diversity goals.Summary. The DEI committee's established place in the organizational structure of the college is essential to ensure fair and appropriate representation of the community it serves. A clearly defined DEI committee with committee composition, roles, responsibilities, and its association with all constituents of the college and community can help achieve its intended strategic goals.

RESUMEN

BACKGROUND: Mild traumatic brain injury (MTBI) causes morbidity and disability worldwide. Pediatric patients are uniquely vulnerable due to developmental and psychosocial factors. Reduced healthcare access in rural/underserved communities impair management and outcome. A knowledge update relevant to current gaps in care is critically needed to develop targeted solutions. METHODS: The National Library of Medicine PubMed database was queried using comprehensive search terms (("mild traumatic brain injury" or "concussion") and ("rural" or "low-income" or "underserved") and ("pediatric" or "child/children")) in the title, abstract, and Medical Subject Headings through December 2022. Fifteen articles on rural/underserved pediatric MTBI/concussion not covered in prior reviews were examined and organized into four topical categories: epidemiology, care practices, socioeconomic factors, and telehealth. RESULTS: Incidences are higher for Individuals in rural regions, minorities, and those aged 0-4 years compared to their counterparts, and are increasing over time. Rural healthcare utilization rates generally exceed urban rates, and favor emergency departments (vs. primary care) for initial injury assessment. Management guidelines require customization to resource-constrained settings for implementation and adoption. Decreased community recognition of the seriousness of injury is a consensus challenge to care provision by clinicians. Low parental education and income were correlated with decreased MTBI knowledge and worse outcome. Telehealth protocols for triage/consultation and rehabilitation were feasible in improving care delivery to rural and remote settings. CONCLUSIONS: Pediatric MTBI/concussion patients in rural/underserved regions experience increased risks of injury, geographic and financial healthcare barriers, and poorer outcomes. Globally, under-reporting of injury has hindered epidemiological understanding. Ongoing MTBI education should be implemented for rural caregivers, schools, and low-income populations to improve community awareness. Telehealth can improve care delivery across acuity settings, and warrants judicious inclusion in triage and treatment protocols.

RESUMEN

BACKGROUND: High-resolution genetic maps are needed in many crops to help characterize the genetic diversity that determines agriculturally important traits. Hybridization to microarrays to detect single feature polymorphisms is a powerful technique for marker discovery and genotyping because of its highly parallel nature. However, microarrays designed for gene expression analysis rarely provide sufficient gene coverage for optimal detection of nucleotide polymorphisms, which limits utility in species with low rates of polymorphism such as lettuce (Lactuca sativa). RESULTS: We developed a 6.5 million feature Affymetrix GeneChip® for efficient polymorphism discovery and genotyping, as well as for analysis of gene expression in lettuce. Probes on the microarray were designed from 26,809 unigenes from cultivated lettuce and an additional 8,819 unigenes from four related species (L. serriola, L. saligna, L. virosa and L. perennis). Where possible, probes were tiled with a 2 bp stagger, alternating on each DNA strand; providing an average of 187 probes covering approximately 600 bp for each of over 35,000 unigenes; resulting in up to 13 fold redundancy in coverage per nucleotide. We developed protocols for hybridization of genomic DNA to the GeneChip® and refined custom algorithms that utilized coverage from multiple, high quality probes to detect single position polymorphisms in 2 bp sliding windows across each unigene. This allowed us to detect greater than 18,000 polymorphisms between the parental lines of our core mapping population, as well as numerous polymorphisms between cultivated lettuce and wild species in the lettuce genepool. Using marker data from our diversity panel comprised of 52 accessions from the five species listed above, we were able to separate accessions by species using both phylogenetic and principal component analyses. Additionally, we estimated the diversity between different types of cultivated lettuce and distinguished morphological types. CONCLUSION: By hybridizing genomic DNA to a custom oligonucleotide array designed for maximum gene coverage, we were able to identify polymorphisms using two approaches for pair-wise comparisons, as well as a highly parallel method that compared all 52 genotypes simultaneously.

RESUMEN

The first single-nucleotide polymorphism (SNP) maps for watermelon [Citrullus lanatus (Thunb.) Matsum. et Nakai] were constructed and compared. Three populations were developed from crosses between two elite cultivars, Klondike Black Seeded × New Hampshire Midget (KBS × NHM), an elite cultivar and wild egusi accession, Strain II × PI 560023 (SII × Egusi) and an elite cultivar and a wild citron accession, ZWRM50 × PI 244019 (ZWRM × Citroides). The SII × Egusi and ZWRM × Citroides F(2) populations consisted of 187 and 182 individuals respectively while the KBS × NHM recombinant inbred line (RIL) population consisted of 164 lines. The length of the genetic maps were 1,438, 1,514 and 1,144 cM with average marker distances of 3.8, 4.2, and 3.4 cM for the KBS × NHM, SII × Egusi and ZWRM × Citroides populations, respectively. Shared markers were used to align the three maps so that the linkage groups (LGs) represented the 11 chromosomes of the species. Marker segregation distortion were observed in all three populations, but was highest (12.7 %) in the ZWRM × Citroides population, where Citroides alleles were favored. The three maps were used to construct a consensus map containing 378 SNP markers with an average distance of 5.1 cM between markers. Phenotypic data was collected for fruit weight (FWT), fruit length (FL), fruit width (FWD), fruit shape index (FSI), rind thickness (RTH) and Brix (BRX) and analyzed for quantitative trait loci (QTL) associated with these traits. A total of 40 QTL were identified in the three populations, including major QTL for fruit size and shape that were stable across genetic backgrounds and environments. The present study reports the first SNP maps for Citrullus and the first map constructed using two elite parents. We also report the first stable QTL associated with fruit size and shape in Citrullus lanatus. These maps, QTL and SNPs should be useful for the watermelon community and represent a significant step towards the potential use of molecular tools in watermelon breeding.

RESUMEN

Bacterial cyclic nucleotide gated (bCNG) channels are generally a nonmechanosensitive subset of the mechanosensitive channel of small conductance (MscS) superfamily. bCNG channels are composed of an MscS channel domain, a linking domain, and a cyclic nucleotide binding domain. Among bCNG channels, the channel domain of Ss-bCNGa, a bCNG channel from Synechocystis sp. PCC 6803, is most identical to Escherichia coli (Ec) MscS. This channel also exhibits limited mechanosensation in response to osmotic downshock assays, making it the only known full-length bCNG channel to respond to hypoosmotic stress. Here, we compare and contrast the ability of Ss-bCNGa to gate in response to mechanical tension with Se-bCNG, a nonmechanosensitive bCNG channel, and Ec-MscS, a prototypical mechanosensitive channel. Compared with Ec-MscS, Ss-bCNGa only exhibits limited mechanosensation, which is most likely a result of the inability of Ss-bCNGa to form the strong lipid contacts needed for significant function. Unlike Ec-MscS, Ss-bCNGa displays a mechanical response that increases with protein expression level, which may result from channel clustering driven by interchannel cation-π interactions.

RESUMEN

OBJECTIVE: Cranioplasty is a technically simple procedure, although one with potentially high rates of complications. The ideal timing of cranioplasty should minimize the risk of complications, but research investigating cranioplasty timing and risk of complications has generated diverse findings. Previous studies have included mixed populations of patients undergoing cranioplasty following decompression for traumatic, vascular, and other cerebral insults, making results challenging to interpret. The objective of the current study was to examine rates of complications associated with cranioplasty, specifically for patients with traumatic brain injury (TBI) receiving this procedure at the authors' high-volume level 1 trauma center over a 25-year time period. METHODS: A single-institution retrospective review was conducted of patients undergoing cranioplasty after decompression for trauma. Patients were identified and clinical and demographic variables obtained from 2 neurotrauma databases. Patients were categorized into 3 groups based on timing of cranioplasty: early (≤ 90 days after craniectomy), intermediate (91-180 days after craniectomy), and late (> 180 days after craniectomy). In addition, a subgroup analysis of complications in patients with TBI associated with ultra-early cranioplasty (< 42 days, or 6 weeks, after craniectomy) was performed. RESULTS: Of 435 patients identified, 141 patients underwent early cranioplasty, 187 patients received intermediate cranioplasty, and 107 patients underwent late cranioplasty. A total of 54 patients underwent ultra-early cranioplasty. Among the total cohort, the mean rate of postoperative hydrocephalus was 2.8%, the rate of seizure was 4.6%, the rate of postoperative hematoma was 3.4%, and the rate of infection was 6.0%. The total complication rate for the entire population was 16.8%. There was no significant difference in complications between any of the 3 groups. No significant differences in postoperative complications were found comparing the ultra-early cranioplasty group with all other patients combined. CONCLUSIONS: In this cohort of patients with TBI, early cranioplasty, including ultra-early procedures, was not associated with higher rates of complications. Early cranioplasty may confer benefits such as shorter or fewer hospitalizations, decreased financial burden, and overall improved recovery, and should be considered based on patient-specific factors.

RESUMEN

INTRODUCTION: To describe the use of the nominal group technique (NGT) to refine pharmacy core roles and to compare these roles with current pharmacy outcomes and other literature to highlight potential deficiencies. METHODS: The NGT process was used for this proposal review. The process was conducted in four key stages: silent generation, round-robin, clarification, and voting. A convenience sampling of five pharmacy faculty and administrators that have researched the areas of practice-readiness and pharmacy competencies formed the panel of participants for the NGT process. RESULTS: Study findings offer seven core roles that define pharmacists' scope of practice: knowledge, patient care skills, professional, scholar, system-based practice/manager, collaborator, and advocate/health promoter. Development of these core roles revealed several missing pharmacy competencies or ones only covered in optional learning objectives: conflict management, professional advocacy, scholarship, empathy, personal health, transitions of care, health outcomes, quality improvement, and health insurance. CONCLUSIONS: The development of pharmacy roles is one way to ensure students are adequately prepared for pharmacy practice following graduation. Mapping of competencies to core professional roles would allow schools/colleges of pharmacy to have one cohesive document to guide pedagogical and assessment practice. More research and consensus building will be needed before these core roles could be disseminated more broadly.

RESUMEN

Background: Traumatic subdural hematomas (SDH) can have devastating neurologic consequences. Acute-on-chronic SDHs are more frequent in the elderly, who have increased comorbidities and perioperative risks. The subdural evacuation port system (SEPS) procedure consists of a twist drill hole connected to a single drain on suction, which can be performed at bedside to evacuate SDHs without requiring general anesthesia. However, a single SEPS can be limited due to inability to evacuate across septations between SDHs of different ages. Purpose: We present to our knowledge the first case of using tandem SEPS to evacuate a multi-loculated SDH. We discuss the technical nuances of the procedure as a treatment option for complex SDHs. Findings: An 86-year-old man with cognitive impairment and recurrent falls presented acutely after ground-level fall with worsening dysarthria and right hemiparesis. Computed tomography scan showed a 11 mm left holohemispheric mixed-density SDH with loculated acute and subacute/chronic components with 2 mm midline shift. Following two interval stability scans, the patient underwent drainage of a superficial chronic component, and a posterolateral acute/subacute component using two sequential SEPS drains at bedside in the intensive care unit. The patient's symptoms markedly improved, drains were removed, and the patient was discharged home with home health on post-procedure day 6. Conclusions: Judicious patient selection and pre-procedural planning can enable the use of tandem SEPS to evacuate multi-loculated SDHs under moderate sedation. Using multiple subdural ports to evacuate complex SDHs should be an option for proceduralists in settings where general anesthesia is not feasible.

RESUMEN

BACKGROUND: Hospital length of stay (HLOS) after traumatic brain injury (TBI) is an important metric of injury severity, resource utilization, and access to post-acute care services. Risk factors for protracted HLOS after TBI require further characterization. METHODS: Data regarding adult inpatients admitted to a single U.S. level 1 trauma center with a diagnosis of acute TBI between August 1, 2019, and April 1, 2022, were extracted from the electronic health record. Patients with extreme HLOS (XHLOS, >99th percentile of institutional TBI HLOS) were compared with those without XHLOS. Socioeconomic status (SES), clinical/injury factors, and discharge disposition were analyzed. RESULTS: In 1638 patients, the median HLOS was 3 days (interquartile range [IQR]: 2-8 days). XHLOS threshold was >70 days (N = 18; range: 72-146 days). XHLOS was associated with younger age (XHLOS/non-XHLOS: 50.4/59.6 years; P = 0.042) and greater proportions with severe TBI (55.6%/11.4%; P < 0.001), low SES (72.2%/31.4%; P < 0.001), and Medicaid insurance (77.8%/30.1%; P < 0.001). XHLOS patients were more likely to die in hospital (22.2%/8.1%) and discharge to post-acute facility (77.8%/16.3%; P < 0.001). No XHLOS patients were discharged to home. In XHLOS patients alive at discharge, medical stability was documented at median 39 days (IQR: 28-58 days) and were hospitalized for another 56 days (IQR: 26.5-78.5 days). CONCLUSIONS: XHLOS patients were more likely to have severe injuries, low SES, and Medicaid. XHLOS is associated with in-hospital mortality and need for post-acute placement. XHLOS patients often demonstrated medical stability long before placement, underscoring complex relationships between SES, health insurance, and outcome. These findings have important implications for quality improvement and resource utilization at acute care hospitals and await validation from larger trials.
