The political polarization of COVID-19 treatments among physicians and laypeople in the United States.

In the United States, liberals and conservatives disagree about facts. To what extent does expertise attenuate these disagreements? To study this question, we compare the polarization of beliefs about COVID-19 treatments among laypeople and critical care physicians. We find that political ideology predicts both groups' beliefs about a range of COVID-19 treatments. These associations persist after controlling for a rich set of covariates, including local politics. We study two potential explanations: a) that partisans are exposed to different information and b) that they interpret the same information in different ways, finding evidence for both. Polarization is driven by preferences for partisan cable news but not by exposure to scientific research. Using a set of embedded experiments, we demonstrate that partisans perceive scientific evidence differently when it pertains to a politicized treatment (ivermectin), relative to when the treatment is not identified. These results highlight the extent to which political ideology is increasingly relevant for understanding beliefs, even among expert decision makers such as physicians.

Association Between Nurse Copatient Illness Severity and Mortality in the ICU.

OBJECTIVES: In the context of traditional nurse-to-patient ratios, ICU patients are typically paired with one or more copatients, creating interdependencies that may affect clinical outcomes. We aimed to examine the effect of copatient illness severity on ICU mortality. DESIGN: We conducted a retrospective cohort study using electronic health records from a multihospital health system from 2018 to 2020. We identified nurse-to-patient assignments for each 12-hour shift using a validated algorithm. We defined copatient illness severity as whether the index patient's copatient received mechanical ventilation or vasoactive support during the shift. We used proportional hazards regression with time-varying covariates to assess the relationship between copatient illness severity and 28-day ICU mortality. SETTING: Twenty-four ICUs in eight hospitals. PATIENTS: Patients hospitalized in the ICU between January 1, 2018, and August 31, 2020. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The main analysis included 20,650 patients and 84,544 patient-shifts. Regression analyses showed a patient's risk of death increased when their copatient received both mechanical ventilation and vasoactive support (hazard ratio [HR]: 1.30; 95% CI, 1.05-1.61; p = 0.02) or vasoactive support alone (HR: 1.82; 95% CI, 1.39-2.38; p < 0.001), compared with situations in which the copatient received neither treatment. However, if the copatient was solely on mechanical ventilation, there was no significant increase in the risk of death (HR: 1.03; 95% CI, 0.86-1.23; p = 0.78). Sensitivity analyses conducted on cohorts with varying numbers of copatients consistently showed an increased risk of death when a copatient received vasoactive support. CONCLUSIONS: Our findings suggest that considering copatient illness severity, alongside the existing practice of considering individual patient conditions, during the nurse-to-patient assignment process may be an opportunity to improve ICU outcomes.

Association Between Medicare's Sepsis Reporting Policy (SEP-1) and the Documentation of a Sepsis Diagnosis in the Clinical Record.

STUDY DESIGN: Interrupted time series analysis of a retrospective, electronic health record cohort. OBJECTIVE: To determine the association between the implementation of Medicare's sepsis reporting measure (SEP-1) and sepsis diagnosis rates as assessed in clinical documentation. BACKGROUND: The role of health policy in the effort to improve sepsis diagnosis remains unclear. PATIENTS AND METHODS: Adult patients hospitalized with suspected infection and organ dysfunction within 6 hours of presentation to the emergency department, admitted to one of 11 hospitals in a multi-hospital health system from January 2013 to December 2017. Clinician-diagnosed sepsis, as reflected by the inclusion of the terms "sepsis" or "septic" in the text of clinical notes in the first two calendar days following presentation. RESULTS: Among 44,074 adult patients with sepsis admitted to 11 hospitals over 5 years, the proportion with sepsis documentation was 32.2% just before the implementation of SEP-1 in the third quarter of 2015 and increased to 37.3% by the fourth quarter of 2017. Of the 9 post-SEP-1 quarters, 8 had odds ratios for a sepsis diagnosis >1 (overall range: 0.98-1.26; P value for a joint test of statistical significance = 0.005). The effects were clinically modest, with a maximum effect of an absolute increase of 4.2% (95% CI: 0.9-7.8) at the end of the study period. The effect was greater in patients who did not require vasopressors compared with patients who required vasopressors ( P value for test of interaction = 0.02). CONCLUSIONS: SEP-1 implementation was associated with modest increases in sepsis diagnosis rates, primarily among patients who did not require vasoactive medications.

A voice-based digital assistant for intelligent prompting of evidence-based practices during ICU rounds.

OBJECTIVE: To evaluate the technical feasibility and potential value of a digital assistant that prompts intensive care unit (ICU) rounding teams to use evidence-based practices based on analysis of their real-time discussions. METHODS: We evaluated a novel voice-based digital assistant which audio records and processes the ICU care team's rounding discussions to determine which evidence-based practices are applicable to the patient but have yet to be addressed by the team. The system would then prompt the team to consider indicated but not yet delivered practices, thereby reducing cognitive burden compared to traditional rigid rounding checklists. In a retrospective analysis, we applied automatic transcription, natural language processing, and a rule-based expert system to generate personalized prompts for each patient in 106 audio-recorded ICU rounding discussions. To assess technical feasibility, we compared the system's prompts to those created by experienced critical care nurses who directly observed rounds. To assess potential value, we also compared the system's prompts to a hypothetical paper checklist containing all evidence-based practices. RESULTS: The positive predictive value, negative predictive value, true positive rate, and true negative rate of the system's prompts were 0.45 ± 0.06, 0.83 ± 0.04, 0.68 ± 0.07, and 0.66 ± 0.04, respectively. If implemented in lieu of a paper checklist, the system would generate 56% fewer prompts per patient, with 50%±17% greater precision. CONCLUSION: A voice-based digital assistant can reduce prompts per patient compared to traditional approaches for improving evidence uptake on ICU rounds. Additional work is needed to evaluate field performance and team acceptance.

Patient and Family Factors Associated with Use of Telemedicine Visits for Pediatric Acute Respiratory Tract Infections, 2018-2019.

Background: Pediatric acute respiratory tract infections (ARTIs) were a common reason for commercial direct-to-consumer (DTC) telemedicine use before the COVID-19 pandemic, but the factors associated with this use are unknown. Objective: To identify child and family factors associated with use of commercial DTC telemedicine for ARTIs in 2018-2019. Methods: We performed a retrospective cohort analysis of claims data from the Optum Clinformatics® Data Mart Database. Among children with ARTI visits, we fitted logit models to examine child and family characteristics associated with DTC telemedicine use. Results: Of 660,725 children with ARTI visits, 12,944 (2.0%) had ≥1 commercial DTC telemedicine encounter. The odds of DTC telemedicine use were higher for children with age ≥12 years, lower parent educational attainment, higher household income, white non-Hispanic race/ethnicity, and residency in the West South Central census division. Conclusion: In 2018-2019, commercial DTC telemedicine use varied with child age, child race/ethnicity parent educational attainment, household income, and geography.

Helicopter versus ground ambulance transport for interfacility transfer of critically ill children.

BACKGROUND: Following initial stabilization, critically ill children often require transfer to a specialized pediatric hospital. While the use of specialized pediatric transport teams has been associated with improved outcomes for these patients, the additional influence of transfer mode (helicopter or ground ambulance) on clinical outcomes remains unknown. METHODS: We investigated the association between transport mode and outcomes among critically ill children transferred to a single pediatric hospital via a specialized pediatric transport team. We designed a retrospective cohort study to reduce indication bias by limiting analysis to patients for whom a helicopter transport was initially requested. We compared outcomes for those who ultimately traveled via helicopter, and for those who ultimately traveled via ground ambulance due to non-clinical factors. RESULTS: We compared transport times, in-hospital mortality, and hospital length of stay by transport mode. Transport time in minutes was shorter for helicopter transports (median = 143, interquartile range [IQR]: 118-184) compared to ground ambulance transports (median = 289, IQR: 213-258; difference in medians = 146, 95% CI: 12 to 168, p < 0.001). In unadjusted analysis, helicopter transport was not associated with a difference in in-hospital mortality (helicopter = 6.0%, ground ambulance = 7.0%; 95% CI for difference: -6.6% to 3.3%; p = 0.64) but was associated with a statistically significant reduction in median hospital days (helicopter = 4, ground ambulance = 5; 95% CI -3 to 0; p = 0.04). In adjusted analyses, there were no statistically significant associations. These results were consistent across sensitivity analyses. CONCLUSIONS: Among critically ill pediatric patients without traumatic injuries transported by a specialty team, those patients who would have been transferred by helicopter if available but were instead transferred by ground ambulance reached their site of definitive care approximately 2.5 h later. Helicopter transport for these patients was not associated with in-hospital mortality, but was potentially associated with reduced hospital length of stay.

Treatment Patterns and Clinical Outcomes After the Introduction of the Medicare Sepsis Performance Measure (SEP-1).

BACKGROUND: Medicare requires that hospitals report on their adherence to the Severe Sepsis and Septic Shock Early Management Bundle (SEP-1). OBJECTIVE: To evaluate the effect of SEP-1 on treatment patterns and patient outcomes. DESIGN: Longitudinal study of hospitals using repeated cross-sectional cohorts of patients. SETTING: 11 hospitals within an integrated health system. PATIENTS: 54 225 encounters between January 2013 and December 2017 for adults with sepsis who were hospitalized through the emergency department. INTERVENTION: Onset of the SEP-1 reporting requirement in October 2015. MEASUREMENTS: Changes in SEP-1-targeted processes, including antibiotic administration, lactate measurement, and fluid administration at 3 hours from sepsis onset; repeated lactate and vasopressor administration for hypotension within 6 hours of sepsis onset; and sepsis outcomes, including risk-adjusted intensive care unit (ICU) admission, in-hospital mortality, and home discharge among survivors. RESULTS: Two years after its implementation, SEP-1 was associated with variable changes in process measures, with the greatest effect being an increase in lactate measurement within 3 hours of sepsis onset (absolute increase, 23.7 percentage points [95% CI, 20.7 to 26.7 percentage points]; P < 0.001). There were small increases in antibiotic administration (absolute increase, 4.7 percentage points [CI, 1.9 to 7.6 percentage points]; P = 0.001) and fluid administration of 30 mL/kg of body weight within 3 hours of sepsis onset (absolute increase, 3.4 percentage points [CI, 1.5 to 5.2 percentage points]; P < 0.001). There was no change in vasopressor administration. There was a small increase in ICU admissions (absolute increase, 2.0 percentage points [CI, 0 to 4.0 percentage points]; P = 0.055) and no changes in mortality (absolute change, 0.1 percentage points [CI, -0.9 to 1.1 percentage points]; P = 0.87) or discharge to home. LIMITATION: Data are from a single health system. CONCLUSION: Implementation of the SEP-1 mandatory reporting program was associated with variable changes in process measures, without improvements in clinical outcomes. Revising the measure may optimize its future effect. PRIMARY FUNDING SOURCE: Agency for Healthcare Research and Quality.

A Randomized Trial of a Family-Support Intervention in Intensive Care Units.

BACKGROUND: Surrogate decision makers for incapacitated, critically ill patients often struggle with decisions related to goals of care. Such decisions cause psychological distress in surrogates and may lead to treatment that does not align with patients' preferences. METHODS: We conducted a stepped-wedge, cluster-randomized trial involving patients with a high risk of death and their surrogates in five intensive care units (ICUs) to compare a multicomponent family-support intervention delivered by the interprofessional ICU team with usual care. The primary outcome was the surrogates' mean score on the Hospital Anxiety and Depression Scale (HADS) at 6 months (scores range from 0 to 42, with higher scores indicating worse symptoms). Prespecified secondary outcomes were the surrogates' mean scores on the Impact of Event Scale (IES; scores range from 0 to 88, with higher scores indicating worse symptoms), the Quality of Communication (QOC) scale (scores range from 0 to 100, with higher scores indicating better clinician-family communication), and a modified Patient Perception of Patient Centeredness (PPPC) scale (scores range from 1 to 4, with lower scores indicating more patient- and family-centered care), as well as the mean length of ICU stay. RESULTS: A total of 1420 patients were enrolled in the trial. There was no significant difference between the intervention group and the control group in the surrogates' mean HADS score at 6 months (11.7 and 12.0, respectively; beta coefficient, -0.34; 95% confidence interval [CI], -1.67 to 0.99; P=0.61) or mean IES score (21.2 and 20.3; beta coefficient, 0.90; 95% CI, -1.66 to 3.47; P=0.49). The surrogates' mean QOC score was better in the intervention group than in the control group (69.1 vs. 62.7; beta coefficient, 6.39; 95% CI, 2.57 to 10.20; P=0.001), as was the mean modified PPPC score (1.7 vs. 1.8; beta coefficient, -0.15; 95% CI, -0.26 to -0.04; P=0.006). The mean length of stay in the ICU was shorter in the intervention group than in the control group (6.7 days vs. 7.4 days; incidence rate ratio, 0.90; 95% CI, 0.81 to 1.00; P=0.045), a finding mediated by the shortened mean length of stay in the ICU among patients who died (4.4 days vs. 6.8 days; incidence rate ratio, 0.64; 95% CI, 0.52 to 0.78; P<0.001). CONCLUSIONS: Among critically ill patients and their surrogates, a family-support intervention delivered by the interprofessional ICU team did not significantly affect the surrogates' burden of psychological symptoms, but the surrogates' ratings of the quality of communication and the patient- and family-centeredness of care were better and the length of stay in the ICU was shorter with the intervention than with usual care.

Advanced Practice Provider-inclusive Staffing Models and Patient Outcomes in Pediatric Critical Care.

BACKGROUND: Pediatric intensive care units (PICUs) are increasingly staffed with advanced practice providers (APPs), supplementing traditional physician staffing models. OBJECTIVES: We evaluate the effect of APP-inclusive staffing models on clinical outcomes and resource utilization in US PICUs. RESEARCH DESIGN: Retrospective cohort study of children admitted to PICUs in 9 states in 2016 using the Healthcare Cost and Utilization Project's State Inpatient Databases. PICU staffing models were assessed using a contemporaneous staffing survey. We used multivariate regression to examine associations between staffing models with and without APPs and outcomes. MEASURES: The primary outcome was in-hospital mortality. Secondary outcomes included odds of hospital acquired conditions and ICU and hospital lengths of stay. RESULTS: The sample included 38,788 children in 40 PICUs. Patients admitted to PICUs with APP-inclusive staffing were younger (6.1±5.9 vs. 7.1±6.2 y) and more likely to have complex chronic conditions (64% vs. 43%) and organ failure on admission (25% vs. 22%), compared with patients in PICUs with physician-only staffing. There was no difference in mortality between PICU types [adjusted odds ratio (AOR): 1.23, 95% confidence interval (CI): 0.83-1.81, P=0.30]. Patients in PICUs with APP-inclusive staffing had lower odds of central line-associated blood stream infections (AOR: 0.76, 95% CI: 0.59-0.98, P=0.03) and catheter-associated urinary tract infections (AOR: 0.73, 95% CI: 0.61-0.86, P<0.001). There were no differences in lengths of stay. CONCLUSIONS: Despite being younger and sicker, children admitted to PICUs with APP-inclusive staffing had no increased odds of mortality and lower odds of some hospital acquired conditions compared with those in PICUs with physician-only staffing. Further research can inform APP integration strategies which optimize outcomes.

Emergency Department and Ambulatory Care Visits in the First Twelve Months of Coverage Under Medicaid Expansion: A Group-Based Trajectory Analysis.

STUDY OBJECTIVE: More than 17 million people have gained health insurance coverage through the Patient Protection and Affordable Care Act's Medicaid expansion. Few studies have examined heterogeneity within the Medicaid expansion population. We do so based on time-varying patterns of emergency department (ED) and ambulatory care use, and characterize diagnoses associated with ED and ambulatory care visits to evaluate whether certain diagnoses predominate in individual trajectories. METHOD: We used group-based multitrajectory modeling to jointly estimate trajectories of ambulatory care and ED utilization in the first 12 months of enrollment among Pennsylvania Medicaid expansion enrollees from 2015 to 2017. RESULTS: Among 601,877 expansion enrollees, we identified 6 distinct groups based on joint trajectories of ED and ambulatory care use. Mean ED use varied across groups from 3.4 to 48.7 visits per 100 enrollees in the first month and between 2.8 and 44.0 visits per 100 enrollees in month 12. Mean ambulatory visit rates varied from 0.0 to 179 visits per 100 enrollees in the first month and from 0.0 to 274 visits in month 12. Rates of ED visits did not change over time, but rates of ambulatory care visits increased by at least 50% among 4 groups during the study period. Groups varied on chronic condition diagnoses, including mental health and substance use disorders, as well as diagnoses associated with ambulatory care visits. CONCLUSION: We found substantial variation in rates of ED and ambulatory care use across empirically defined subgroups of Medicaid expansion enrollees. We also identified heterogeneity among the diagnoses associated with these visits. This data-driven approach may be used to target resources to encourage efficient use of ED services and support engagement with ambulatory care clinicians.

Effective Care Practices in Patients Receiving Prolonged Mechanical Ventilation. An Ethnographic Study.

Rationale: Patients receiving prolonged mechanical ventilation experience low survival rates and incur high healthcare costs. However, little is known about how to optimally organize and manage their care.Objectives: To identify a set of effective care practices for patients receiving prolonged mechanical ventilation.Methods: We performed a focused ethnographic evaluation at eight long-term acute care hospitals in the United States ranking in either the lowest or highest quartile of risk-adjusted mortality in at least four of the five years between 2007 and 2011.Measurements and Main Results: We conducted 329 hours of direct observation, 196 interviews, and 39 episodes of job shadowing. Data were analyzed using thematic content analysis and a positive-negative deviance approach. We found that high- and low-performing hospitals differed substantially in their approach to care. High-performing hospitals actively promoted interdisciplinary communication and coordination using a range of organizational practices, including factors related to leadership (e.g., leaders who communicate a culture of quality improvement), staffing (e.g., lower nurse-to-patient ratios and ready availability of psychologists and spiritual care providers), care protocols (e.g., specific yet flexible respiratory therapy-driven weaning protocols), team meetings (e.g., interdisciplinary meetings that include direct care providers), and the physical plant (e.g., large workstations that allow groups to interact). These practices were believed to facilitate care that is simultaneously goal directed and responsive to individual patient needs, leading to more successful liberation from mechanical ventilation and improved survival.Conclusions: High-performing long-term acute care hospitals employ several organizational practices that may be helpful in improving care for patients receiving prolonged mechanical ventilation.

Economic Analysis of Mandated Protocolized Sepsis Care in New York Hospitals.

OBJECTIVES: Initial evidence suggests that state-level regulatory mandates for sepsis quality improvement are associated with decreased sepsis mortality. However, sepsis mandates require financial investments on the part of hospitals and may lead to increased spending. We evaluated the effects of the 2013 New York State sepsis regulations on the costs of care for patients hospitalized with sepsis. DESIGN: Retrospective cohort study using state discharge data from the U.S. Healthcare Costs and Utilization Project and a comparative interrupted time series analytic approach. Costs were calculated from admission-level charge data using hospital-specific cost-to-charge ratios. SETTING: General, short stay, acute care hospitals in New York, and four control states: Florida, Massachusetts, Maryland, and New Jersey. PATIENTS: All patients hospitalized with sepsis between January 1, 2011, and September 30, 2015. INTERVENTIONS: The 2013 New York mandate that all hospitals develop and implement protocols for sepsis identification and treatment, educate staff, and report performance data to the state. MEASUREMENTS AND MAIN RESULTS: The analysis included 1,026,664 admissions in 520 hospitals. Mean unadjusted costs per hospitalization in New York State were $42,036 ± $60,940 in the pre-regulation period and $39,719 ± $59,063 in the post-regulation period, compared with $34,642 ± $52,403 pre-regulation and $31,414 ± $48,155 post-regulation in control states. In the comparative interrupted time series analysis, the regulations were not associated with a significant difference in risk-adjusted mean cost per hospitalization (p = 0.12) or risk-adjusted mean cost per hospital day (p = 0.44). For example, in the 10th quarter after implementation of the regulations, risk-adjusted mean cost per hospitalization was $3,627 (95% CI, -$681 to $7,934) more than expected in New York State relative to control states. CONCLUSIONS: Mandated protocolized sepsis care was not associated with significant changes in hospital costs in patients hospitalized with sepsis in New York State.

The Influence of Stereotactic Body Radiation Therapy Adoption on Prostate Cancer Treatment Patterns.

PURPOSE: To our knowledge it is unknown whether stereotactic body radiation therapy of prostate cancer is a substitute for other radiation treatments or surgery, or for expanding the pool of patients who undergo treatment instead of active surveillance. MATERIALS AND METHODS: Using SEER (Surveillance, Epidemiology, and End Results)-Medicare we identified men diagnosed with prostate cancer between 2007 and 2011. We developed physician-hospital networks by identifying the treating physician of each patient based on the primary treatment received and subsequently assigning each physician to a hospital. We examined the relative distribution of prostate cancer treatments stratified by whether stereotactic body radiation therapy was performed in a network by fitting logistic regression models with robust SEs to account for patient clustering in networks. RESULTS: We identified 344 physician-hospital networks, including 30 (8.7%) and 314 (91.3%) in which stereotactic body radiation therapy was and was not performed, respectively. Networks in which that therapy was and was not done did not differ with time in the performance of robotic and radical prostatectomy, and active surveillance (all p >0.05). The relationship with intensity modulated radiation therapy did not show any consistent temporal pattern. In networks in which it was performed less intensity modulated radiation therapy was initially done but there were similar rates in later years. Brachytherapy trends differed among networks in which stereotactic body radiation therapy was vs was not performed with a lower brachytherapy rate in networks in which stereotactic body radiation therapy was done (p=0.03). CONCLUSIONS: Surgery and active surveillance rates did not differ in networks in which stereotactic body radiation therapy was vs was not performed but when that therapy was done there was a lower brachytherapy rate. Stereotactic body radiation therapy may represent more of an alternative to brachytherapy than to active surveillance.

Association Between Intravenous Fluid Bolus and Biomarker Trajectory During Prehospital Care.

Background: Patients with acute illness who receive intravenous (IV) fluids prior to hospital arrival may have a lower in-hospital mortality. To better understand whether this is a direct treatment effect or epiphenomenon of downstream care, we tested the association between a prehospital fluid bolus and the change in inflammatory cytokines measured at prehospital and emergency department timepoints in a sample of non-trauma, non-cardiac arrest patients at risk for critical illness. Methods: In a prospective cohort study, we screened 4,013 non-trauma, non-cardiac arrest encounters transported by City of Pittsburgh Emergency Medical Services (EMS) to 2 hospitals from August 2013 to February 2014. In 345 patients, we measured prehospital biomarkers (IL-6, IL-10, and TNF) at 2 time points: the time of prehospital IV access placement by EMS and at ED arrival. We determined the relative change for marker X as: ([XED - XEMS]/XEMS). We determined the risk-adjusted association between prehospital IV fluid bolus and relative change for each marker using multivariable linear regression. Results: Among 345 patients, 88 (26%) received a prehospital IV fluid bolus and 257 (74%) did not. Compared to patients who did not receive prehospital fluids, median prehospital IL-6 was greater initially in subjects receiving a prehospital IV fluid bolus (22.3 [IQR 6.4-113] vs. 11.5 [IQR 5.5-47.6]). Prehospital IL-10 and TNF were similar in both groups (IL-10: 3.5 [IQR 2.2-25.6] vs. 3.0 [IQR 1.9-9.0]; TNF: 7.5 [IQR 6.4-10.4] vs. 6.9 [IQR 6.0-8.3]). After adjustment for demographics, illness severity, and prehospital transport time, we observed a relative decrease in IL-6 at hospital arrival in those receiving a prehospital fluid bolus (adjusted ß = -10.0, 95% CI: -19.4, -0.6, p = 0.04), but we did not detect a significant change in IL-10 (p = 0.34) or TNF (p = 0.53). Conclusions: Among non-trauma, non-cardiac arrest patients at risk for critical illness, a prehospital IV fluid bolus was associated with a relative decrease in IL-6, but not IL-10 or TNF.

Determinants of Intensive Care Unit Telemedicine Effectiveness. An Ethnographic Study.

RATIONALE: Telemedicine is an increasingly common care delivery strategy in the ICU. However, ICU telemedicine programs vary widely in their clinical effectiveness, with some studies showing a large mortality benefit and others showing no benefit or even harm. OBJECTIVES: To identify the organizational factors associated with ICU telemedicine effectiveness. METHODS: We performed a focused ethnographic evaluation of 10 ICU telemedicine programs using site visits, interviews, and focus groups in both facilities providing remote care and the target ICUs. Programs were selected based on their change in risk-adjusted mortality after adoption (decreased mortality, no change in mortality, and increased mortality). We used a constant comparative approach to guide data collection and analysis. MEASUREMENTS AND MAIN RESULTS: We conducted 460 hours of direct observation, 222 interviews, and 18 focus groups across six telemedicine facilities and 10 target ICUs. Data analysis revealed three domains that influence ICU telemedicine effectiveness: 1) leadership (i.e., the decisions related to the role of the telemedicine, conflict resolution, and relationship building), 2) perceived value (i.e., expectations of availability and impact, staff satisfaction, and understanding of operations), and 3) organizational characteristics (i.e., staffing models, allowed involvement of the telemedicine unit, and new hire orientation). In the most effective telemedicine programs these factors led to services that are viewed as appropriate, integrated, responsive, and consistent. CONCLUSIONS: The effectiveness of ICU telemedicine programs may be influenced by several potentially modifiable factors within the domains of leadership, perceived value, and organizational structure.

Radiation oncologists' attitudes and beliefs about intensity-modulated radiation therapy and stereotactic body radiation therapy for prostate cancer.

BACKGROUND: To better understand how radiation oncologists perceive intensity-modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) for prostate cancer and how these perceptions may influence treatment decisions. METHODS: We conducted semi-structured interviews of radiation oncologists between January-May, 2016. We used a purposeful sampling technique to select participants across a wide range of experience, regions, and practice types. Two trained qualitative researchers used an inductive, iterative approach to code transcripts and identify themes. We then used content analysis and thematic analysis of the coded transcripts to understand radiation oncologists' attitudes and beliefs about IMRT and SBRT. RESULTS: Thematic saturation was achieved after 20 interviews. Participants were affiliated with academic (n = 13; 65%), private (n = 5; 25%), and mixed (n = 2; 10%) practices and had a wide range of clinical experience (median 19 years; range 4-49 years). Analysis of interview transcripts revealed four general themes: 1) most radiation oncologists offered surgery, brachytherapy, IMRT, and active surveillance for low-risk patients; 2) there was no consensus on the comparative effectiveness of IMRT and SBRT; 3) key barriers to adopting SBRT included issues related to insurance, reimbursement, and practice inertia; and 4) despite these barriers, most participants envisioned SBRT use increasing over the next 5-10 years. CONCLUSIONS: In the absence of strong opinions about effectiveness, nonclinical factors influence the choice of radiation treatment. Despite a lack of consensus, most participants agreed SBRT may become a standard of care in the future.

Effects of a Personalized Web-Based Decision Aid for Surrogate Decision Makers of Patients With Prolonged Mechanical Ventilation: A Randomized Clinical Trial.

Background: Treatment decisions commonly have to be made in intensive care units (ICUs). These decisions are difficult for surrogate decision makers and often lead to decisional conflict, psychological distress, and treatments misaligned with patient preferences. Objective: To determine whether a decision aid about prolonged mechanical ventilation improved prognostic concordance between surrogate decision makers and clinicians compared with a usual care control. Design: Multicenter, parallel, randomized, clinical trial. (ClinicalTrials.gov: NCT01751061). Setting: 13 medical and surgical ICUs at 5 hospitals. Participants: Adult patients receiving prolonged mechanical ventilation and their surrogates, ICU physicians, and ICU nurses. Intervention: A Web-based decision aid provided personalized prognostic estimates, explained treatment options, and interactively clarified patient values to inform a family meeting. The control group received information according to usual care practices followed by a family meeting. Measurements: The primary outcome was improved concordance on 1-year survival estimates, measured with the clinician-surrogate concordance scale (range, 0 to 100 percentage points; higher scores indicate more discordance). Secondary and additional outcomes assessed the experiences of surrogates (psychological distress, decisional conflict, and quality of communication) and patients (length of stay and 6-month mortality). Outcomes assessors were blinded to group allocation. Results: The study enrolled 277 patients, 416 surrogates, and 427 clinicians. Concordance improvement did not differ between intervention and control groups (mean difference in score change from baseline, -1.7 percentage points [95% CI, -8.3 to 4.8 percentage points]; P = 0.60). Surrogates' postintervention estimates of patients' 1-year prognoses did not differ between intervention and control groups (median, 86.0% [interquartile range {IQR}, 50.0%] vs. 92.5% [IQR, 47.0%]; P = 0.23) and were substantially more optimistic than results of a validated prediction model (median, 56.0% [IQR, 43.0%]) and physician estimates (median, 50.0% [IQR, 55.5%]). Eighty-two intervention surrogates (43%) favored a treatment option that was more aggressive than their report of patient preferences. Although intervention surrogates had greater reduction in decisional conflict than control surrogates (mean difference in change from baseline, 0.4 points [CI, 0.0 to 0.7 points]; P = 0.041), other surrogate and patient outcomes did not differ. Limitation: Contamination among clinicians could have biased results toward the null hypothesis. Conclusion: A decision aid about prolonged mechanical ventilation did not improve prognostic concordance between clinicians and surrogates, reduce psychological distress among surrogates, or alter clinical outcomes. Decision support in acute care settings may require greater individualized attention for both the cognitive and affective challenges of decision making.

National Performance on the Medicare SEP-1 Sepsis Quality Measure.

OBJECTIVES: The Centers for Medicare and Medicaid Services requires hospitals to report compliance with a sepsis treatment bundle as part of its Inpatient Quality Reporting Program. We used recently released data from this program to characterize national performance on the sepsis measure, known as SEP-1. DESIGN: Cross-sectional study of United States hospitals participating in the Centers for Medicare and Medicaid Services Hospital Inpatient Quality Reporting Program linked to Centers for Medicare and Medicaid Services' Healthcare Cost Reporting Information System. SETTING: General, short-stay, acute-care hospitals in the United States. MEASUREMENTS AND MAIN RESULTS: We examined the hospital factors associated with reporting SEP-1 data, the hospital factors associated with performance on the SEP-1 measure, and the relationship between SEP-1 performance and performance on other quality measures related to time-sensitive medical conditions. A total of 3,283 hospitals were eligible for the analysis, of which 2,851 (86.8%) reported SEP-1 performance data. SEP-1 reporting was more common in larger, nonprofit hospitals. The most common reason for nonreporting was an inadequate case volume. Among hospitals reporting SEP-1 performance data, overall bundle compliance was generally low, but it varied widely across hospitals (mean and SD: 48.9% ± 19.4%). Compared with hospitals with worse SEP-1 performance, hospitals with better SEP-1 performance tended to be smaller, for-profit, nonteaching, and with intermediate-sized ICUs. Better hospital performance on SEP-1 was associated with higher rates of timely head CT interpretation for stroke patients (rho = 0.16; p < 0.001), more frequent aspirin administration for patients with chest pain or heart attacks (rho = 0.24; p < 0.001) and shorter median time to electrocardiogram for patients with chest pain (rho = -0.12; p < 0.001). CONCLUSIONS: The majority of eligible hospitals reported SEP-1 data, and overall bundle compliance was highly variable. SEP-1 performance was associated with structural hospital characteristics and performance on other measures of hospital quality, providing preliminary support for SEP-1 performance as a marker of timely hospital sepsis care.

Effects of Changes in ICU Bed Supply on ICU Utilization.

BACKGROUND: The availability of intensive care unit (ICU) beds may influence the demand for critical care. Although small studies support a model of supply-induced demand in the ICU, there is a paucity of system-wide data. OBJECTIVE: The objective of this study was to determine the relationship between ICU bed supply and ICU admission in United States hospitals. RESEARCH DESIGN: Retrospective cohort study using all-payer inpatient records from Florida, Massachusetts, New Jersey, New York, and Washington from 2010 to 2012, linked to hospital data from Medicare's Healthcare Cost Reporting Information System. SUBJECTS: Three patient groups with a low likelihood of benefiting from ICU admission-low severity patients with acute myocardial infarction and pulmonary embolism; and high severity patients with metastatic cancer at the end of life. MEASURES: We compared the risk-adjusted probability of ICU admission at hospitals that increased their ICU bed supply over time to matched hospitals that did not, using a difference-in-differences approach. RESULTS: For patients with acute myocardial infarction, ICU supply increases were associated with an increase in the probability of ICU admission that diminished over time. For patients with pulmonary embolism, there was a trend toward an association between change in ICU supply and ICU admission that did not meet statistical significance. For patients with metastatic cancer, admission to hospitals with an increasing ICU supply was not associated with changes in the probability of ICU admission. CONCLUSIONS: Increases in ICU bed supply were associated with inconsistent changes in the probability of ICU admission that varied across patient subgroups.

Effects of a Telephone- and Web-based Coping Skills Training Program Compared with an Education Program for Survivors of Critical Illness and Their Family Members. A Randomized Clinical Trial.

RATIONALE: Many survivors of critical illness and their family members experience significant psychological distress after patient discharge. OBJECTIVES: To compare the effects of a coping skills training (CST) program with an education program on patient and family psychological distress. METHODS: In this five-center clinical trial, adult patients who received mechanical ventilation for more than 48 hours and one family member of each patient were randomized to six weekly CST telephone sessions plus access to a study website or a critical illness education program. MEASUREMENTS AND MAIN RESULTS: The primary outcome was the patient Hospital Anxiety and Depression Scale (HADS) score at 3 months. Secondary outcomes included 3- and 6-month HADS subscales and the Impact of Events Scale-Revised. Among the 175 patients randomized to CST (n = 86) or education (n = 89), there was no significant difference between CST and education in either 3-month HADS scores (difference, 1.3; 95% confidence interval [CI], -0.9 to 3.4; P = 0.24) or secondary patient and family outcomes. In prespecified analyses, among patients with high baseline distress (n = 60), CST recipients had greater improvement in 6-month HADS score (difference, -4.6; 95% CI, -8.6 to -0.6; P = 0.02) than the education group. Among patients ventilated longer than 7 days (n = 47), education recipients had greater improvement in 3-month HADS score (difference, -4.0; 95% CI, -8.1 to -0.05; P = 0.047) than the CST group. CONCLUSIONS: CST did not improve psychological distress symptoms compared with an education program. However, CST improved symptoms of distress at 6 months among patients with high baseline distress, whereas the education program improved distress at 3 months among those ventilated for more than 7 days. Future efforts to address psychological distress among critical illness survivors should target high-risk populations. Clinical trial registered with www.clinicaltrials.gov (NCT01983254).
