Persistent Opioid Use Following Pediatric Nonfatal Firearm Injury.

OBJECTIVE: Firearms are a major cause of pediatric injury. An analysis of opioid use following pediatric firearm injury has not previously been reported. Our objective was to determine the prevalence and factors associated with persistent opioid use among pediatric nonfatal firearm injury victims. METHODS: We performed a retrospective cohort study using 2015-18 claims data from the Merative MarketScan Multi-State Medicaid and Commercial Databases, utilizing International Classification of Diseases, Tenth Revision codes for firearm injury and National Drug Codes for opioids. Dispensed opioid claims were used as a proxy for opioid use. Opioid exposure was defined both dichotomously and continuously (by the total number of opioid days prescribed) in the 30 days following discharge from firearm injury index encounter. Persistent opioid use was defined as ≥1 opioid claim(s) in the 90 to 270 days following index encounter. Multivariable logistic regression analysis was performed to determine whether covariates of interest were associated with greater odds of persistent opioid use. RESULTS: Our cohort consisted of 2110 children who experienced nonfatal firearm injury (mean age 13.5, 80.9% male, 79.5% Medicaid) with 608 children (28.8%) exposed to opioids. Of patients exposed to opioids, 10.4% developed persistent opioid use. In adjusted analyses, each opioid day dispensed during the exposure period represented 5% greater odds of experiencing persistent opioid use. CONCLUSIONS: Clinicians caring for children injured by firearms should be aware of the risk of developing persistent opioid use and balance that risk with the need to sufficiently control pain.

Differences in rehabilitation evaluation access for rural and socially disadvantaged stroke survivors.

BACKGROUND: Most stroke survivors have ongoing deficits and report unmet needs. Despite evidence that rehabilitation improves stroke survivors' function, access to occupational and physical therapy is limited. Describing access to care for disadvantaged communities for different levels of stroke severity will provide proportions used to create Markov economic models to demonstrate the value of rehabilitation. OBJECTIVES: The objective of this study was to explore differences in the frequency of rehabilitation evaluations via outpatient therapy and home health for Medicare Part B ischemic stroke survivors in rural and socially disadvantaged locations. METHODS: We completed a retrospective, descriptive cohort analysis using the 2018 and 2019 5% Medicare Limited Data Sets (LDS) from the Centers for Medicare and Medicaid Services using STROBE guidelines for observational studies. We extracted rehabilitation Current Procedural Terminology (CPT) codes for those who received occupational or physical therapy to examine differences in therapy evaluations for rural and socially disadvantaged populations. RESULTS: Of the 9,076 stroke survivors in this cohort, 44.2% did not receive any home health or outpatient therapy. Of these, 64.7% had a moderate or severe stroke, indicating an unmet need for therapy. Only 2.0% of stroke survivors received outpatient occupational therapy within the first year Rural and socially disadvantaged communities accessed rehabilitation evaluations at lower rates than general stroke survivors. CONCLUSIONS: These findings describe the poor access to home health and outpatient rehabilitation for stroke survivors, particularly in traditionally underserved populations. These results will influence future economic evaluations of interventions aimed at improving access to care.

Health Care Utilization After Nonfatal Firearm Injuries.

OBJECTIVES: Despite the high incidence of firearm injuries, little is known about health care utilization after nonfatal childhood firearm injuries. This study aimed to describe health care utilization and costs after a nonfatal firearm injury among Medicaid and commercially insured youth using a propensity score matched analysis. METHODS: We conducted a propensity score matched cohort analysis using 2015 to 2018 Medicaid and Commercial Marketscan data comparing utilization in the 12-months post firearm injury for youth aged 0 to 17. We matched youth with a nonfatal firearm injury 1:1 to comparison noninjured youth on demographic and preindex variables. Outcomes included inpatient hospitalizations, emergency department (ED) visits, and outpatient visits as well as health care costs. Following propensity score matching, regression models estimated relative risks of the health care utilization outcomes, adjusting for demographic and clinical covariates. RESULTS: We identified 2110 youth with nonfatal firearm injury. Compared with matched noninjured youth, firearm injured youth had a 5.31-fold increased risk of inpatient hospitalization (95% confidence interval [CI] 3.93-7.20), 1.49-fold increased risk of ED visit (95% CI 1.37-1.62), and 1.06-fold increased risk of outpatient visit (95% CI 1.03-1.10) 12-months postinjury. Adjusted 12-month postindex costs were $7581 (95% CI $7581-$8092) for injured youth compared with $1990 (95% CI $1862-2127) for comparison noninjured youth. CONCLUSIONS: Youth who suffer nonfatal firearm injury have a significantly increased risk of hospitalizations, ED visits, outpatient visits, and costs in the 12 months after injury when compared with matched youth. Applied to the 11 258 US youth with nonfatal firearm injuries in 2020, estimates represent potential population health care savings of $62.9 million.

Evaluation of a Telehealth-Enabled Pilot Program to Address Intensive Care Unit Health Care Worker Mental Health Distress.

Introduction: Health care workers (HCWs) are at heightened risk of adverse mental health events (AMHEs) and burnout with resultant impact on health care staffing, outcomes, and costs. We piloted a telehealth-enabled mental health screening and support platform among HCWs in the intensive care unit (ICU) setting at a tertiary care center. Methods: A survey consisting of validated screening tools was electronically disseminated to a potential cohort of 178 ICU HCWs. Participants were given real-time feedback on their results and those at risk were provided invitations to meet with resiliency clinicians. Participants were further invited to engage in a 3-month longitudinal assessment of their well-being through repeat surveys and a weekly text-based check-in coupled with self-help tips. Programmatic engagement was evaluated and associations between at-risk scores and engagement were assessed. Qualitative input regarding programmatic uptake and acceptance was gathered through key informant interviews. Results: Fifty (28%) HCWs participated in the program. Half of the participants identified as female, and most participants were white (74%) and under the age of 50 years (93%). Nurses (38%), physicians-in-training (24%), and faculty-level physicians (20%) engaged most frequently. There were 19 (38%) requests for an appointment with a resiliency clinician. The incidence of clinically significant symptoms of AMHEs and burnout was high but not clearly associated with engagement. Additional programmatic tailoring was encouraged by key informants while time was identified as a barrier to program engagement. Discussion: A telehealth-enabled platform is a feasible approach to screening at-risk HCWs for AMHEs and can facilitate engagement with support services.

Driving Pressure, Elastance, and Outcomes in a Real-World Setting: A Bi-Center Analysis of Electronic Health Record Data.

Emerging evidence suggests the potential importance of inspiratory driving pressure (DP) and respiratory system elastance (ERS) on outcomes among patients with the acute respiratory distress syndrome. Their association with outcomes among heterogeneous populations outside of a controlled clinical trial is underexplored. We used electronic health record (EHR) data to characterize the associations of DP and ERS with clinical outcomes in a real-world heterogenous population. DESIGN: Observational cohort study. SETTING: Fourteen ICUs in two quaternary academic medical centers. PATIENTS: Adult patients who received mechanical ventilation for more than 48 hours and less than 30 days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: EHR data from 4,233 ventilated patients from 2016 to 2018 were extracted, harmonized, and merged. A minority of the analytic cohort (37%) experienced a Pao2/Fio2 of less than 300. A time-weighted mean exposure was calculated for ventilatory variables including tidal volume (VT), plateau pressures (PPLAT), DP, and ERS. Lung-protective ventilation adherence was high (94% with VT < 8.5 mL/kg, time-weighted mean VT = 6. 8 mL/kg, 88% with PPLAT ≤ 30 cm H2O). Although time-weighted mean DP (12.2 cm H2O) and ERS (1.9 cm H2O/[mL/kg]) were modest, 29% and 39% of the cohort experienced a DP greater than 15 cm H2O or an ERS greater than 2 cm H2O/(mL/kg), respectively. Regression modeling with adjustment for relevant covariates determined that exposure to time-weighted mean DP (> 15 cm H2O) was associated with increased adjusted risk of mortality and reduced adjusted ventilator-free days independent of adherence to lung-protective ventilation. Similarly, exposure to time-weighted mean ERS greater than 2 cm H2O/(mL/kg) was associated with increased adjusted risk of mortality. CONCLUSIONS: Elevated DP and ERS are associated with increased risk of mortality among ventilated patients independent of severity of illness or oxygenation impairment. EHR data can enable assessment of time-weighted ventilator variables and their association with clinical outcomes in a multicenter real-world setting.

Characterizing Swallowing Impairment in a Post-Lung Transplant Population.

BACKGROUND: Lung transplant recipients carry significant pre- and post-lung transplant dysphagia risk factors related to altered respiratory-swallow coordination as well as acute injury and decompensation resulting in the acute post-lung transplant recovery period. However, we are only beginning to understand the potential physiological contributors to altered swallowing in this population. METHOD: A retrospective, cross-sectional, cohort study of post-lung transplant patients was performed. All participants received a modified barium swallow study (MBSS) as part of standard care during their acute hospitalization using the Modified Barium Swallow Impairment Profile (MBSImP) protocol and scoring metric. A combination of MBSImP scores, Penetration-Aspiration Scale (PAS) scores, Functional Oral Intake Scale (FOIS) scores, International Dysphagia Diet Standardization Initiative (IDDSI) scale levels, and the time from lung transplant to MBSS was collected, as well as measures of swallowing impairment and swallowing-related outcomes. Differences in swallowing physiology and swallowing-related outcomes between participants with typical versus atypical PAS were explored. RESULTS: Forty-two participants met our prespecified inclusion criteria. We identified atypical laryngeal penetration and/or aspiration in 52.4% of our post-lung transplant cohort. Silent aspiration occurred in 75% of those patients who aspirated. Comparing typical versus atypical PAS scores, we found statistically significant associations with laryngeal elevation (Component 8), p < .0001; anterior hyoid excursion (Component 9), p = .0046; epiglottic movement (Component 10), p = .0031; laryngeal vestibule closure (Component 11), p < .0001; pharyngeal stripping (Component 12), p = .0058; pharyngeal total scores, p = .0001; FOIS scores, p = .00264; and IDDSI liquid levels, p = .0009. CONCLUSIONS: Swallowing impairment resulting in abnormal bolus invasion is prevalent in post-lung transplant patients. Airway invasion in this cohort was related to pharyngeal swallow impairment and resulted in modified oral intake. Our findings help expand upon prior literature, which only reported the incidence of aspiration and pathological laryngeal penetration. Our results suggest that the potential for aerodigestive system impairment and negative sequela should not be underestimated in the post-lung transplant population.

Determining the Marginal Cost Differences of a Telehealth Versus an In-person Occupational Therapy Evaluation Session for Stroke Survivors Using Time-driven Activity-based Costing.

OBJECTIVE: To estimate the marginal cost differences and care delivery process of a telerehabilitation vs outpatient session. DESIGN: This study used a time-driven activity-based costing approach including (1) observation of rehabilitation sessions and creation of manual time stamps, (2) structured and recorded interviews with 2 occupational therapists familiar with outpatient therapy and 2 therapists familiar with telerehabilitation, (3) collection of standard wages for providers, and (4) the creation of an iterative flowchart of both an outpatient and telerehabilitation session care delivery process. SETTING: Telerehabilitation and outpatient therapy evaluation. PARTICIPANTS: Three therapists familiar with care deliver for telerehabilitation or outpatient therapy (N=3). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Marginal cost difference between telerehabilitation and outpatient therapy evaluations. RESULTS: Overall, telerehabilitation ($225.41) was more costly than outpatient therapy ($168.29) per session for a cost difference of $57.12. Primary time drivers of this finding were initial phone calls (0 minutes for OP therapists vs 35 minutes for TR) and post documentation (5 minutes for OP vs 30 minutes for TR) demands for telerehabilitation. CONCLUSIONS: Telerehabilitation is an emerging platform with the potential to reduce costs, improve health care inequities, and facilitate better patient outcomes. Improvements in documentation practices, staffing, technology, and reimbursement structuring would allow for a more successful translation.

Mental Health Care Utilization Among Children and Adolescents With a Firearm Injury.

Importance: Firearm injuries are a leading cause of morbidity and mortality among US children and adolescents. Despite evidence demonstrating mental health sequelae for children and adolescents who have experienced a firearm injury, little is known about mental health care utilization after a firearm injury. Objective: To evaluate mental health care utilization in the 12 months after a firearm injury among Medicaid-insured and commercially insured children and adolescents compared with propensity score-matched controls. Design, Setting, and Participants: This propensity score-matched retrospective cohort analysis assessed 2127 children and adolescents, aged 0 to 17 years, with a firearm injury that occurred between January 1, 2016, and December 31, 2017, compared with 2127 matched controls using MarketScan Medicaid and commercial claims data. Claims data were analyzed 12 months before and after injury, with the total study period spanning from January 1, 2015, to December 31, 2018. Exposure: Nonfatal firearm injury. Main Outcomes and Measures: The primary outcome of interest was a dichotomous variable representing any mental health care utilization in the 12 months after injury. Secondary outcomes included psychotherapy utilization, substance use-related utilization, and a psychotropic medication prescription. Logistic regression modeling was used to estimate relative risks with adjusted analyses of dichotomous outcomes. Results: The overall cohort consisted of 4254 children and adolescents, of whom 2127 (mean [SD] age, 13.5 [4.1] years; 1722 [81.0%] male) had an initial encounter for a firearm injury and an equal number of matched controls (mean [SD] age, 13.5 [4.1] years; 1720 [80.9%] male). Children and adolescents with a firearm injury had a 1.40 times greater risk (95% CI, 1.25-1.56; P < .001) of utilizing mental health services in the 12 months after their injury compared with children and adolescents without a firearm injury, after controlling for potential confounders. Children and adolescents with a firearm injury had a 1.23 times greater risk (95% CI, 1.06-1.43; P = .007) of utilizing psychotherapy and a 1.40 times greater risk (95% CI, 1.19-1.64; P < .001) of substance use-related utilization. Among those who experienced a firearm injury, Black children and adolescents were 1.64 times more likely (95% CI, 1.23-2.19; P < .001) to utilize mental health care compared with White children and adolescents. Conclusions and Relevance: This propensity score-matched cohort study found that children and adolescents with a firearm injury had a greater risk of utilizing mental health services in the 12 months after their injury compared with those without an injury, and significant racial disparities were associated with use of mental health services. The findings suggest that health care practitioners should be aware of this increased risk and ensure adequate mental health follow-up for these patients.

Elevated Driving Pressure and Elastance Does Not Increase In-Hospital Mortality Among Obese and Severely Obese Patients With Ventilator Dependent Respiratory Failure.

Existing recommendations for mechanical ventilation are based on studies that under-sampled or excluded obese and severely obese individuals. Objective: To determine if driving pressure (DP) and total respiratory system elastance (Ers) differ among normal/overweight (body mass index [BMI] < 30 kg/m2), obese, and severely obese ventilator-dependent respiratory failure (VDRF) patients and if there any associations with clinical outcomes. Design Setting and Participants: Retrospective observational cohort study during 2016-2018 at two tertiary care academic medical centers using electronic health record data from the first 2 full days of mechanical ventilation. The cohort was stratified by BMI classes to measure median DP, time-weighted mean tidal volume, plateau pressure, and Ers for each BMI class. Setting and Participants: Mechanically ventilated patients in medical and surgical ICUs. Main Outcomes and Measures: Primary outcome and effect measures included relative risk of in-hospital mortality, ventilator-free days, ICU length of stay, and hospital length of stay with multivariable adjustment. Results: The cohort included 3,204 patients with 976 (30.4%) and 382 (11.9%) obese and severely obese patients, respectively. Severe obesity was associated with a DP greater than or equal to 15 cm H2O (relative risk [RR], 1.51 [95% CI, 1.26-1.82]) and Ers greater than or equal to 2 cm H2O/(mL/kg) (RR, 1.31 [95% CI, 1.14-1.49]). Despite elevated DP and Ers, there were no differences in in-hospital mortality, ventilator-free days, or ICU length of stay among all three groups. Conclusions and Relevance: Despite higher DP and ERS among obese and severely obese VDRF patients, there were no differences in in-hospital mortality or duration of mechanical ventilation, suggesting that DP has less prognostic value in obese and severely obese VDRF patients.

Abnormal Esophageal Clearance Identified During Modified Barium Swallow Study in an Acute Poststroke Cohort.

PURPOSE: Dysphagia impacts many poststroke survivors with wide-ranging prevalence in the acute and chronic phases. One relatively unexplored manifestation of poststroke swallowing impairment is that of primary or co-occurring esophageal dysphagia. The incidence of esophageal dysphagia in this population is unknown despite the shared neuroanatomy and physiology with the oropharynx. We aimed to determine the presence of abnormal esophageal clearance in an acute poststroke sample using the Modified Barium Swallow Impairment Profile (MBSImP) Component 17 (esophageal clearance) as our outcome measure. METHOD: We performed a retrospective, cross-sectional, cohort study of 57 poststroke patients with acute, first-ever, ischemic strokes. All participants received a modified barium swallow study (MBSS) using the MBSImP protocol and scoring metrics. Swallowing impairment was determined using a combination of MBSImP scores and Penetration-Aspiration Scale scores. Swallowing outcome measures were collected including Functional Oral Intake Scale and International Dysphagia Diet Standardization Initiative (IDDSI) scores. We performed tests of association and logistic regression analysis to determine if statistically significant associations exist between judgments of esophageal clearance and other swallowing impairments and/or swallowing outcome measures. RESULTS: In our study of poststroke patients who received an MBSS as part of their care, 57.9% had abnormal esophageal clearance. Statistically significant associations were also identified in measures of pharyngeal physiology (MBSImP scores) and swallowing outcome measures (IDDSI scores and alternate means of nutrition). CONCLUSIONS: Abnormal esophageal clearance was identified in greater than half of our poststroke patients. There is a dearth of scientific research regarding esophageal function poststroke. While esophageal visualization during the MBSS is not diagnostic of esophageal impairment, it may serve as an indicator for those poststroke patients who require dedicated esophageal testing to best determine the full nature of their swallowing pathophysiology and make the most effective treatment recommendations.

Incidence of Poststroke Depression in Patients With Poststroke Dysphagia.

PURPOSE: Poststroke dysphagia and poststroke depression (PSD) can have devastating effects on stroke survivors, including increased burden of care, higher health care costs, poor quality of life, and greater mortality; however, there is a dearth of research examining depression in patients diagnosed with dysphagia after stroke. Thus, we aimed to study the incidence of PSD in patients with poststroke dysphagia to provide foundational knowledge about this patient population. METHOD: We conducted a retrospective, cross-sectional study of individuals with a primary diagnosis of acute ischemic stroke (AIS) and secondary diagnoses of dysphagia and/or depression using administrative claims data from the 2017 Medicare 5% Limited Data Set. RESULTS: The proportion of depression diagnosis in patients with poststroke dysphagia was significantly higher than the proportion of depression diagnosis in those without poststroke dysphagia during acute hospitalization: 12.01% versus 9.52%, respectively (p = .003). CONCLUSIONS: Our results demonstrated that persons with poststroke dysphagia were as, or slightly more, likely to have PSD compared to the general stroke population, and to our knowledge, they establish the first reported incidence of PSD in Medicare patients with dysphagia after AIS. Future research is warranted to further explore the effects of PSD on poststroke dysphagia.

Disparities in Use of Patient Portals Among Adults in Family Medicine.

OBJECTIVE: This study examined patient portal utilization by analyzing the pattern of time and feature use of patients, and thus to identify functionalities of portal use and patient characteristics that may inform future strategies to enhance communication and care coordination through online portals. METHODS: We conducted a retrospective study of patients at 18 family medicine clinics over a 5-year period using access log records in the electronic health record database. Dimensionality reduction analysis was applied to group portal functionalities into 4 underlying feature domains: messaging, health information management, billing/insurance, and resource/education. Negative binomial regression analysis was used to evaluate how patient and practice characteristics affected the use of each feature domain. RESULTS: Patients with more chronic conditions, lab tests, or prescriptions generally showed greater patient portal usage. However, patients who were male, elderly, in minority groups, or living in rural areas persistently had lower portal usage. Individuals on public insurance were also less likely than those on commercial insurance to use patient portals, although Medicare patients showed greater portal usage on health information management features, and uninsured patients had greater usage on viewing resource/education features. Having Internet access only affected the use of messaging features. CONCLUSION: Efforts to enroll patients in online portals do not guarantee patients will use the portals to manage their health. When considering the use of patient portals for improving telehealth, clinicians need to be aware of technological, socioeconomic, and cultural challenges faced by their patients.

Clinician attitudes and concordance with self-assessed and actual intravenous fluid prescribing patterns: A single-institution evaluation of survey and electronic prescribing data.

BACKGROUND: Recent studies suggest that balanced fluids improve inpatient outcomes compared to normal saline. The objective of this study was to obtain insights into clinicians' knowledge, attitudes and perceived prescribing practices concerning IV isotonic fluids and to analyze perceived prescribing in the context of actual prescribing. METHODS: This study, conducted at a single center (Medical University of South Carolina), included 1) a cross-sectional survey of physicians and advanced practice providers (APPs) (7/2019-8/2019) and 2) review electronic health record (EHR) claims data (2/2018-1/2019) to quantify the prescribing patterns of isotonic fluids. RESULTS: Clinicians perceived ordering equivalent amounts of normal saline and balanced fluids although normal saline ordering predominated (59.7%). There was significant variation in perceived and actual ordering across specialties, with internal medicine/subspecialty and emergency medicine clinicians reporting preferential use of normal saline and surgical/subspecialty and anesthesia clinicians reporting preferential use of balanced fluids (p < 0.0001). Clinicians who self-reported providing care in an intensive care unit (ICU) reported more frequent use of balanced fluids than non-ICU clinicians (p = 0.03). Actual prescribing data mirrored these differences. Clinicians' self-reported use of continuous infusions (p = 0.0006) and beliefs regarding the volume of fluid required to cause harm (p = 0.003) were also associated with self-reported differences in fluid prescribing. Clinician experience, most clinical considerations (e.g., indications, contraindications, barriers to using a specific fluid), and fluid cost were not associated with differential prescribing. CONCLUSIONS: Persistent normal saline utilization is associated with certain specialties, care locations, and the rate and volume of fluid administered, but not with other clinical considerations or cost. These findings can guide interventions to improve evidence-based fluid prescribing.

The Impact of Timing on Clinical and Economic Outcomes During Inter-ICU Transfer of Acute Respiratory Failure Patients: Time and Tide Wait for No One.

Approximately one in 30 patients with acute respiratory failure (ARF) undergoes an inter-ICU transfer. Our objectives are to describe inter-ICU transfer patterns and evaluate the impact of timing of transfer on patient-centered outcomes. DESIGN: Retrospective, quasi-experimental study. SETTING: We used the Healthcare Cost and Utilization Project State Inpatient Databases in five states (Florida, Maryland, Mississippi, New York, and Washington) during 2015-2017. PARTICIPANTS: We selected patients with International Classification of Diseases, 9th and 10th Revision codes of respiratory failure and mechanical ventilation who underwent an inter-ICU transfer (n = 6,718), grouping as early (≤ 2 d) and later transfers (3+ d). To control for potential selection bias, we propensity score matched patients (1:1) to model propensity for early transfer using a priori defined patient demographic, clinical, and hospital variables. MAIN OUTCOMES: Inhospital mortality, hospital length of stay (HLOS), and cumulative charges related to inter-ICU transfer. RESULTS: Six-thousand seven-hundred eighteen patients with ARF underwent inter-ICU transfer, 68% of whom (n = 4,552) were transferred early (≤ 2 d). Propensity score matching yielded 3,774 well-matched patients for this study. Unadjusted outcomes were all superior in the early versus later transfer cohort: inhospital mortality (24.4% vs 36.1%; p < 0.0001), length of stay (8 vs 22 d; p < 0.0001), and cumulative charges ($118,686 vs $308,977; p < 0.0001). Through doubly robust multivariable modeling with random effects at the state level, we found patients who were transferred early had a 55.8% reduction in risk of inhospital mortality than those whose transfer was later (relative risk, 0.442; 95% CI, 0.403-0.497). Additionally, the early transfer cohort had lower HLOS (20.7 fewer days [13.0 vs 33.7; p < 0.0001]), and lower cumulative charges ($66,201 less [$192,182 vs $258,383; p < 0.0001]). CONCLUSIONS AND RELEVANCE: Our study is the first to use a large, multistate sample to evaluate the practice of inter-ICU transfers in ARF and also define early and later transfers. Our findings of favorable outcomes with early transfer are vital in designing future prospective studies evaluating evidence-based transfer procedures and policies.

A Modification of Time-Driven Activity-Based Costing for Comparing Cost of Telehealth and In-Person Visits.

Introduction: Cost studies of telehealth (TH) and virtual visits are few and report mixed results of the economic impact of virtual care and TH. Largely missing from the literature are studies that identify the cost of delivering TH versus in-person care. The objective was to demonstrate a modified time-driven activity-based costing (TDABC) approach to compare weighted labor cost of an in-person pediatric clinic sick visit before COVID-19 to the same virtual and in-person sick-visit during COVID-19. Methods: We examined visits before and during COVID-19 using: (1) recorded structured interviews with providers; (2) iterative workflow mapping; (3) electronic health records time stamps for validation; (4) standard cost weights for wages; and (5) clinic CPT billing code mix for complexity weighs. We examined the variability in estimated time using a decision tree model and Monte Carlo simulations. Results: Workflow charts were created for the clinic before COVID-19 and during COVID-19. Using TDABC and simulations for varying time, the weighted cost of clinic labor for sick visit before COVID-19 was $54.47 versus $51.55 during COVID-19. Discussion: The estimated mean labor cost for care during the pandemic has not changed from the pre-COVID period; however, this lack of a difference is largely because of the increased use of TH. Conclusions: Our TDABC approach is feasible to use under virtual working conditions; requires minimal provider time for execution; and generates detailed cost estimates that have "face validity" with providers and are relevant for economic evaluation.

Determinants of hospital variability in perioperative red blood cell transfusions during coronary artery bypass graft surgery.

OBJECTIVE: To identify to what extent distinguishing patient and procedural characteristics can explain center-level transfusion variation during coronary artery bypass grafting surgery. METHODS: Observational cohort study using the Perfusion Measures and Outcomes Registry from 43 adult cardiac surgical programs from July 1, 2011, to July 1, 2017. Iterative multilevel logistic regression models were constructed using patient demographic characteristics, preoperative risk factors, and intraoperative conservation strategies to progressively explain center-level transfusion variation. RESULTS: Of the 22,272 adult patients undergoing isolated coronary artery bypass surgery using cardiopulmonary bypass, 7241 (32.5%) received at least 1 U allogeneic red blood cells (range, 10.9%-59.9%). When compared with patients who were not transfused, patients who received at least 1 U red blood cells were older (68 vs 64 years; P < .001), were women (41.5% vs 15.9%; P < .001), and had a lower body surface area (1.93 m2 vs 2.07 m2; P < .001), respectively. Among the models explaining center-level transfusion variability, the intraclass correlation coefficients were 0.07 for model 1 (random intercepts), 0.12 for model 2 (patient factors), 0.14 for model 3 (intraoperative factors), and 0.11 for model 4 (combined). The coefficient of variation for center-level transfusion rates were 0.31, 0.29, 0.40, and 0.30 for models 1 through 4, respectively. The majority of center-level variation could not be explained through models containing both patient and intraoperative factors. CONCLUSIONS: The results suggest that variation in center-level red blood cells transfusion cannot be explained by patient and procedural factors alone. Investigating organizational culture and programmatic infrastructure may be necessary to better understand variation in transfusion practices.

Predicting upper extremity motor improvement following therapy using EEG-based connectivity in chronic stroke.

BACKGROUND: Uncertain prognosis presents a challenge for therapists in determining the most efficient course of rehabilitation treatment for individual patients. Cortical Sensorimotor network connectivity may have prognostic utility for upper extremity motor improvement because the integrity of the communication within the sensorimotor network forms the basis for neuroplasticity and recovery. OBJECTIVE: To investigate if pre-intervention sensorimotor connectivity predicts post-stroke upper extremity motor improvement following therapy. METHODS: Secondary analysis of a pilot triple-blind randomized controlled trial. Twelve chronic stroke survivors underwent 2-week task-practice therapy, while receiving vibratory stimulation for the treatment group and no stimulation for the control group. EEG connectivity was obtained pre-intervention. Motor improvement was quantified as change in the Box and Block Test from pre to post-therapy. The association between ipsilesional sensorimotor connectivity and motor improvement was examined using regression, controlling for group. For negative control, contralesional/interhemispheric connectivity and conventional predictors (initial clinical motor score, age, time post-stroke, lesion volume) were examined. RESULTS: Greater ipsilesional sensorimotor alpha connectivity was associated with greater upper extremity motor improvement following therapy for both groups (p < 0.05). Other factors were not significant. CONCLUSION: EEG connectivity may have a prognostic utility for individual patients' upper extremity motor improvement following therapy in chronic stroke.

Impact of Community Health Workers on Access to Care for Rural Populations in the United States: A Systematic Review.

Community Health Worker (CHW) interventions have shown potential to reduce inequities for underserved populations. However, there is a lack of support for CHW integration in the delivery of health care. This may be of particular importance in rural areas in the Unites States where access to care remains problematic. This review aims to describe CHW interventions and their outcomes in rural populations in the US. Peer reviewed literature was searched in PubMed and PsycINFO for articles published in English from 2015 to February 2021. Title and abstract screening was performed followed by full text screening. Quality of the included studies was assessed using the Downs and Black score. A total of 26 studies met inclusion criteria. The largest proportion were pre-post program evaluation or cohort studies (46.2%). Many described CHW training (69%). Almost a third (30%) indicated the CHW was integrated within the health care team. Interventions aimed to provide health education (46%), links to community resources (27%), or both (27%). Chronic conditions were the concern for most interventions (38.5%) followed by women's health (34.6%). Nearly all studies reported positive improvement in measured outcomes. In addition, studies examining cost reported positive return on investment. This review offers a broad overview of CHW interventions in rural settings in the United States. It provides evidence that CHW can improve access to care in rural settings and may represent a cost-effective investment for the healthcare system.

Missing data methods for intensive care unit SOFA scores in electronic health records studies: results from a Monte Carlo simulation.

Aim: Missing data cause problems through decreasing sample size and the potential for introducing bias. We tested four missing data methods on the Sequential Organ Failure Assessment (SOFA) score, an intensive care research severity adjuster. Methods: Simulation study using 2015-2017 electronic health record data, where the complete dataset was sampled, missing SOFA score elements imposed and performance examined of four missing data methods - complete case analysis, median imputation, zero imputation (recommended by SOFA score creators) and multiple imputation (MI) - on the outcome of in-hospital mortality. Results: MI performed well, whereas other methods introduced varying amounts of bias or decreased sample size. Conclusion: We recommend using MI in analyses where SOFA score component values are missing in administrative data research.

A comparison of administrative claims-based risk predictors for pediatric asthma.

OBJECTIVES: Head-to-head comparisons are needed to determine the most accurate and appropriate administrative claims-based exacerbation risk predictor for emergency department (ED) visits and hospitalizations among children with asthma. STUDY DESIGN: Retrospective cohort study. METHODS: We analyzed 2013-2014 MarketScan Medicaid data. Children aged 2 to 17 years were included. Seven risk predictors were compared for accuracy in predicting 3-month subsequent ED visits/hospitalizations for asthma: 3-month rolling asthma medication ratio (AMR), Healthcare Effectiveness Data and Information Set (HEDIS) criteria, revised HEDIS criteria, quarterly short-acting ß-agonist (SABA) claims, prior ED visit, prior hospitalization, and prior ED visit or hospitalization. Sensitivity, specificity, positive and negative predictive value (NPV), and percentage of population identified as high risk were compared for each risk predictor utilizing the McNemar test to identify statistically significant differences in risk prediction accuracy. RESULTS: A total of 214,452 children were included; the mean age was 7.8 years. HEDIS and revised HEDIS identified prohibitively large cohorts as high risk (67% and 48%, respectively). For the remaining measures, the NPV range is narrow (97%-99%), indicating high performance at identifying patients who would not benefit from intervention. The ED visit and ED/hospitalization measures have superior sensitivities (44% and 49%, respectively) compared with pharmacy claims-based measures (AMR [5%] and SABA count [10%]). Pharmacy claims-based measures identify a smaller proportion of patients as high risk and maintain high NPV. CONCLUSIONS: Pharmacy-based asthma exacerbation risk predictors such as the AMR and SABA count can rule out low-risk patients with a high degree of specificity and NPV, which is a primary goal of real-time risk monitoring in pediatric asthma.
