Reducing Physical Therapy Consults for Patients With High Functional Mobility in the Acute Medical Inpatient Setting: A Difference-in-Difference Analysis.

OBJECTIVE: To evaluate the effectiveness of clinical decision support for reducing misallocation of physical therapy (PT) consults. DESIGN: A prospective quasi-experimental study. Between October 2018 and November 2021, routinely documented data on functional status and physical therapy referrals were collected from electronic medical records. SETTING: Hospital Medicine and General Internal Medicine service lines at a large quaternary academic medical center. PARTICIPANTS: 20,810 adult patients hospitalized on any of the included treatment (hospital medicine) or control (general internal medicine) service lines. MAIN OUTCOME MEASURE: The primary outcome was "change in proportion of misallocated PT consults" measured as likelihood of PT consults for patients admitted with high functional mobility scores. Changes in the primary outcome from the pre-intervention to post-intervention period were compared in the control and treatment groups using propensity score-weighted difference-in-differences multivariable logit regression adjusting for clinically relevant covariates. INTERVENTION: The intervention period was measured for 20 months and consisted of a clinical decision support tool embedded in the daily note templates for hospital medicine providers. The tool provided education on patient mobility scores and their relation to need for PT consult. The tool was rolled out without any further announcements or education. RESULTS: Our cohort included 20,810 unique admissions (mean age 58.9, 55% women, 83% Black). Post-intervention, the likelihood of PT referrals for patients with high baseline mobility (AM-PAC >18) decreased by 7.3% (P<.001) for the treatment group compared with control, adjusted for age, sex, race, ethnicity, length-of-stay, and mobility change. CONCLUSION: Mobility score-based clinical decision support can decrease unneeded PT consults in the inpatient setting. This could help allocate therapy time for at-risk patients while also having a positive effect on health care systems.

Association between physical therapy frequency and postacute care for a national cohort of patients hospitalized with pneumonia.

BACKGROUND: Annually more than 300,000 patients hospitalized for pneumonia need postacute care. Patients and systems prefer home discharge, but physical limitations often necessitate postacute care. It is unknown whether frequency of physical therapy in the hospital affects postacute care discharges. OBJECTIVE: Examine the relationship between physical therapy visit frequency and disposition among a national sample of patients hospitalized with pneumonia. DESIGNS: Observational cohort study. SETTING: Acute care hospital. PARTICIPANTS: Adult patients with primary diagnosis of pneumonia in the Premier Data Set who received physical therapy in the hospital during a 5-day window, with therapy on at least days 1 and 5. INTERVENTION: Physical therapy visit frequency. MAIN OUTCOME AND MEASURES: Discharge disposition (home or postacute care). RESULTS: We included 18,886 patients from 595 hospitals. Just over half were discharged home (n = 9638; 51.0%) and 558 (2.95%) died. Patients getting more frequent therapy were older, non-Hispanic white, treated in small non-teaching rural hospitals in the West, Midwest, or South, and had fewer severe illness indicators. In adjusted models, patients who received physical therapy on 100% of days were 7% [(95% confidence interval, 4.3-9.7), p < .0001] more likely to go home than patients who received physical therapy on 40% of days. As a falsification test, we found that there was no relationship between physical therapy frequency and all-cause mortality. Physical therapy visit frequency was positively associated with discharge to home. Increasing visit frequency of physical therapy in hospitals might reduce the need for postacute care, but randomized controlled trials are needed to confirm the effect.

Physical therapy provision for patients with pneumonia in US hospitals.

BACKGROUND: Physical therapy (PT) appears beneficial for hospitalized patients. Little is known about PT practice patterns and costs across hospitals. OBJECTIVE: To examine whether receiving PT is associated with specific patient and hospital characteristics for patients with pneumonia. We also explored the variability in PT service provision and costs between hospitals. METHODS: We included administrative claims from 2010 to 2015 in the Premier Healthcare Database, inclusive of 644 US hospitals. We examined associations between receiving at least one PT visit and patient (age, race, insurance, intensive care utilization, comorbidity status, and length of stay) and hospital (academic status, rurality, size, and location) characteristics. Exploratory measures included timing and proportion of days with PT visits, and per-visit and per-admission costs. RESULTS: Of 768,010 patients, 49% had PT. After adjustment, older age most significantly increased the probability of receiving PT (+38.0% if >80 vs. ≤50 years). Higher comorbidity burden, longer length of stay, and hospitalization in an urban setting were also associated with higher probability. Hospitalization in the South most significantly decreased the probability (-9.1% vs. Midwest). Patients without Medicare and Non-White patients also had lower probability. Median (interquartile range) days to first visit was 2 (1-4). Mean proportion of days with a visit was 35% ± 20%. Median per-visit cost was $88.90 [$56.70-$130.90] and per-admission was $224.00 [$137.80-$369.20]. CONCLUSION: Both clinical (intensive care utilization and comorbidity status) and non-clinical (age, race, rurality, location) factors were associated with receiving PT. Within and between hospitals, there was high variability in the number and frequency of visits, and costs.

Defining Potential Overutilization of Physical Therapy Consults on Hospital Medicine Services.

Appropriate use of inpatient physical therapy services is important for preventing hospital-associated disability (HAD). We assessed potential overutilization of physical therapy consults on hospital medicine services using the Activity Measure-Post Acute Care (AM-PAC) score. Our sample included 3592 unique admissions (mean age, 66 years; 48% women) at a large academic medical center. Based on an AM-PAC cutoff of >43.63 (raw score, 18) in patients who were discharged to home, 38% of physical therapy consults were considered "potential overutilization." Combined with age <65 years, 18% of consults remained "potential overutilization." After adjustment for age, sex, and length of stay, patients admitted with high mobility scores were 5.38 times more likely to be discharged to home (95% CI, 4.36-2.89) compared with those with low mobility scores. Being more judicious with physical therapy consults and reserving skilled therapy for at-risk patients could help prevent HAD while also having a positive impact on healthcare systems.

Sleep Disturbances in Frontline Health Care Workers During the COVID-19 Pandemic: Social Media Survey Study.

BACKGROUND: During the COVID-19 pandemic, health care workers are sharing their challenges, including sleep disturbances, on social media; however, no study has evaluated sleep in predominantly US frontline health care workers during the COVID-19 pandemic. OBJECTIVE: The aim of this study was to assess sleep among a sample of predominantly US frontline health care workers during the COVID-19 pandemic using validated measures through a survey distributed on social media. METHODS: A self-selection survey was distributed on Facebook, Twitter, and Instagram for 16 days (August 31 to September 15, 2020), targeting health care workers who were clinically active during the COVID-19 pandemic. Study participants completed the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI), and they reported their demographic and career information. Poor sleep quality was defined as a PSQI score ≥5. Moderate-to-severe insomnia was defined as an ISI score >14. The Mini-Z Burnout Survey was used to measure burnout. Multivariate logistic regression tested associations between demographics, career characteristics, and sleep outcomes. RESULTS: A total of 963 surveys were completed. Participants were predominantly White (894/963, 92.8%), female (707/963, 73.4%), aged 30-49 years (692/963, 71.9%), and physicians (620/963, 64.4%). Mean sleep duration was 6.1 hours (SD 1.2). Nearly 96% (920/963, 95.5%) of participants reported poor sleep (PSQI). One-third (288/963, 30%) reported moderate or severe insomnia. Many participants (554/910, 60.9%) experienced sleep disruptions due to device use or had nightmares at least once per week (420/929, 45.2%). Over 50% (525/932, 56.3%) reported burnout. In multivariable logistic regressions, nonphysician (odds ratio [OR] 2.4, 95% CI 1.7-3.4), caring for patients with COVID-19 (OR 1.8, 95% CI 1.2-2.8), Hispanic ethnicity (OR 2.2, 95% CI 1.4-3.5), female sex (OR 1.6, 95% CI 1.1-2.4), and having a sleep disorder (OR 4.3, 95% CI 2.7-6.9) were associated with increased odds of insomnia. In open-ended comments (n=310), poor sleep was mapped to four categories: children and family, work demands, personal health, and pandemic-related sleep disturbances. CONCLUSIONS: During the COVID-19 pandemic, nearly all the frontline health care workers surveyed on social media reported poor sleep, over one-third reported insomnia, and over half reported burnout. Many also reported sleep disruptions due to device use and nightmares. Sleep interventions for frontline health care workers are urgently needed.

Targeting the metabolic plasticity of multiple myeloma with FDA-approved ritonavir and metformin.

PURPOSE: We have previously demonstrated that ritonavir targeting of glycolysis is growth inhibitory and cytotoxic in a subset of multiple myeloma cells. In this study, our objective was to investigate the metabolic basis of resistance to ritonavir and to determine the utility of cotreatment with the mitochondrial complex I inhibitor metformin to target compensatory metabolism. EXPERIMENTAL DESIGN: We determined combination indices for ritonavir and metformin, impact on myeloma cell lines, patient samples, and myeloma xenograft growth. Additional evaluation in breast, melanoma, and ovarian cancer cell lines was also performed. Signaling connected to suppression of the prosurvival BCL-2 family member MCL-1 was evaluated in multiple myeloma cell lines and tumor lysates. Reliance on oxidative metabolism was determined by evaluation of oxygen consumption, and dependence on glutamine was assessed by estimation of viability upon metabolite withdrawal in the context of specific metabolic perturbations. RESULTS: Ritonavir-treated multiple myeloma cells exhibited increased reliance on glutamine metabolism. Ritonavir sensitized multiple myeloma cells to metformin, effectively eliciting cytotoxicity both in vitro and in an in vivo xenograft model of multiple myeloma and in breast, ovarian, and melanoma cancer cell lines. Ritonavir and metformin effectively suppressed AKT and mTORC1 phosphorylation and prosurvival BCL-2 family member MCL-1 expression in multiple myeloma cell lines in vitro and in vivo. CONCLUSIONS: FDA-approved ritonavir and metformin effectively target multiple myeloma cell metabolism to elicit cytotoxicity in multiple myeloma. Our studies warrant further investigation into repurposing ritonavir and metformin to target the metabolic plasticity of myeloma to more broadly target myeloma heterogeneity and prevent the reemergence of chemoresistant aggressive multiple myeloma.

Xanthine oxidase-derived ROS upregulate Egr-1 via ERK1/2 in PA smooth muscle cells; model to test impact of extracellular ROS in chronic hypoxia.

Exposure of newborn calves to chronic hypoxia causes pulmonary artery (PA) hypertension and remodeling. Previous studies showed that the redox-sensitive transcription factor, early growth response-1 (Egr-1), is upregulated in the PA of chronically hypoxic calves and regulates cell proliferation. Furthermore, we established in mice a correlation between hypoxic induction of Egr-1 and reduced activity of extracellular superoxide dismutase (EC-SOD), an antioxidant that scavenges extracellular superoxide. We now hypothesize that loss of EC-SOD in chronically hypoxic calves leads to extracellular superoxide-mediated upregulation of Egr-1. To validate our hypothesis and identify the signaling pathways involved, we utilized PA tissue from normoxic and chronically hypoxic calves and cultured calf and human PA smooth muscle cells (PASMC). Total SOD activity was low in the PA tissue, and only the extracellular SOD component decreased with hypoxia. PA tissue of hypoxic calves showed increased oxidative stress and increased Egr-1 mRNA. To mimic the in vivo hypoxia-induced extracellular oxidant imbalance, cultured calf PASMC were treated with xanthine oxidase (XO), which generates extracellular superoxide and hydrogen peroxide. We found that 1) XO increased Egr-1 mRNA and protein, 2) XO induced the phosphorylation of ERK1/2 and, 3) pretreatment with an ERK1/2 inhibitor prevented induction of Egr-1 by XO. siRNA knock-down of EC-SOD in human PASMC also upregulated Egr-1 mRNA and protein, activated ERK1/2, and enhanced SMC proliferation and reduced apoptosis. We conclude that an oxidant/antioxidant imbalance arising from loss of EC-SOD in the PA with chronic hypoxia induces Egr-1 via activation of ERK1/2 and contributes to pulmonary vascular remodeling.
