ICU Utilization After Implementation of Minor Severe Pneumonia Criteria in Real-Time Electronic Clinical Decision Support.

OBJECTIVES: To determine if the implementation of automated clinical decision support (CDS) with embedded minor severe community-acquired pneumonia (sCAP) criteria was associated with improved ICU utilization among emergency department (ED) patients with pneumonia who did not require vasopressors or positive pressure ventilation at admission. DESIGN: Planned secondary analysis of a stepped-wedge, cluster-controlled CDS implementation trial. SETTING: Sixteen hospitals in six geographic clusters from Intermountain Health; a large, integrated, nonprofit health system in Utah and Idaho. PATIENTS: Adults admitted to the hospital from the ED with pneumonia identified by: 1) discharge International Classification of Diseases , 10th Revision codes for pneumonia or sepsis/respiratory failure and 2) ED chest imaging consistent with pneumonia, who did not require vasopressors or positive pressure ventilation at admission. INTERVENTIONS: After implementation, patients were exposed to automated, open-loop, comprehensive CDS that aided disposition decision (ward vs. ICU), based on objective severity scores (sCAP). MEASUREMENTS AND MAIN RESULTS: The analysis included 2747 patients, 1814 before and 933 after implementation. The median age was 71, median Elixhauser index was 17, 48% were female, and 95% were Caucasian. A mixed-effects regression model with cluster as the random effect estimated that implementation of CDS utilizing sCAP increased 30-day ICU-free days by 1.04 days (95% CI, 0.48-1.59; p < 0.001). Among secondary outcomes, the odds of being admitted to the ward, transferring to the ICU within 72 hours, and receiving a critical therapy decreased by 57% (odds ratio [OR], 0.43; 95% CI, 0.26-0.68; p < 0.001) post-implementation; mortality within 72 hours of admission was unchanged (OR, 1.08; 95% CI, 0.56-2.01; p = 0.82) while 30-day all-cause mortality was lower post-implementation (OR, 0.71; 95% CI, 0.52-0.96; p = 0.03). CONCLUSIONS: Implementation of electronic CDS using minor sCAP criteria to guide disposition of patients with pneumonia from the ED was associated with safe reduction in ICU utilization.

Alveolar macrophages from EVALI patients and e-cigarette users: a story of shifting phenotype.

Exposure to e-cigarette vapors alters important biologic processes including phagocytosis, lipid metabolism, and cytokine activity in the airways and alveolar spaces. Little is known about the biologic mechanisms underpinning the conversion to e-cigarette, or vaping, product use-associated lung injury (EVALI) from normal e-cigarette use in otherwise healthy individuals. We compared cell populations and inflammatory immune populations from bronchoalveolar lavage fluid in individuals with EVALI to e-cigarette users without respiratory disease and healthy controls and found that e-cigarette users with EVALI demonstrate a neutrophilic inflammation with alveolar macrophages skewed towards inflammatory (M1) phenotype and cytokine profile. Comparatively, e-cigarette users without EVALI demonstrate lower inflammatory cytokine production and express features associated with a reparative (M2) phenotype. These data indicate macrophage-specific changes are occurring in e-cigarette users who develop EVALI.

A Pragmatic, Stepped-Wedge, Cluster-controlled Clinical Trial of Real-Time Pneumonia Clinical Decision Support.

Rationale: Care of emergency department (ED) patients with pneumonia can be challenging. Clinical decision support may decrease unnecessary variation and improve care. Objectives: To report patient outcomes and processes of care after deployment of electronic pneumonia clinical decision support (ePNa): a comprehensive, open loop, real-time clinical decision support embedded within the electronic health record. Methods: We conducted a pragmatic, stepped-wedge, cluster-controlled trial with deployment at 2-month intervals in 16 community hospitals. ePNa extracts real-time and historical data to guide diagnosis, risk stratification, microbiological studies, site of care, and antibiotic therapy. We included all adult ED patients with pneumonia over the course of 3 years identified by International Classification of Diseases, 10th Revision discharge coding confirmed by chest imaging. Measurements and Main Results: The median age of the 6,848 patients was 67 years (interquartile range, 50-79), and 48% were female; 64.8% were hospital admitted. Unadjusted mortality was 8.6% before and 4.8% after deployment. A mixed effects logistic regression model adjusting for severity of illness with hospital cluster as the random effect showed an adjusted odds ratio of 0.62 (0.49-0.79; P < 0.001) for 30-day all-cause mortality after deployment. Lower mortality was consistent across hospital clusters. ePNa-concordant antibiotic prescribing increased from 83.5% to 90.2% (P < 0.001). The mean time from ED admission to first antibiotic was 159.4 (156.9-161.9) minutes at baseline and 150.9 (144.1-157.8) minutes after deployment (P < 0.001). Outpatient disposition from the ED increased from 29.2% to 46.9%, whereas 7-day secondary hospital admission was unchanged (5.2% vs. 6.1%). ePNa was used by ED clinicians in 67% of eligible patients. Conclusions: ePNa deployment was associated with improved processes of care and lower mortality. Clinical trial registered with www.clinicaltrials.gov (NCT03358342).

Disparities in Speech and Language Delay Among Children With Aural Atresia.

OBJECTIVE: To describe risk factors for speech and language delay in a diverse population of children with aural atresia. METHODS: Retrospective chart review was performed from 2012 to 2020 at UCSF Benioff Children's Hospital to identify children with aural atresia evaluated for speech, language, or auditory skills delays. Ninety-five children with aural atresia, conductive hearing loss, and assessment of speech, language, or auditory skills delay were included. Demographic and clinical data were analyzed to identify predictors of speech and language delay. Cohort and case-control analyses were performed to determine risk factors for delayed intervention, and for ultimate delays in speech, language, or auditory skills. RESULTS: Children exhibited a wide diversity of race/ethnicity, primary home language, geography, and insurance status. Eighty-nine percent had unilateral aural atresia. Forty-eight percent had delays in speech, language, or auditory skills. Most children used hearing aids (84%), had educational accommodations (84%), and received speech therapy (63%). In a univariate retrospective cohort analysis, public-insured ( p = 0.004), non-English speaking ( p = 0.002) and non-white/non-Hispanic children ( p = 0.007) were found to be significantly less likely to be fit with hearing aids in infancy. Children with delays were fit with hearing aids at later ages. In a multivariate case-control analysis, primary home language was a significant predictor for presence of delays [OR, 3.9 (95% CI: 1.2-13.2), p = 0.03]. CONCLUSIONS: Disparities due to insurance type, primary language, and race/ethnicity are associated with delays in hearing aid fitting for children with aural atresia. Earlier, hearing amplification is correlated with reduced risk for speech, language, and auditory skills delay. These findings can help identify at-risk children for targeted support.

Monitoring HIV Preexposure Prophylaxis Use Among Men Who Have Sex With Men in Washington State: Findings From an Internet-Based Survey.

BACKGROUND: Many state and local health departments now promote and support the use of HIV preexposure prophylaxis (PrEP), yet monitoring use of the intervention at the population level remains challenging. METHODS: We report the results of an online survey designed to measure PrEP use among men who have sex with men (MSM) in Washington State. Data on the proportion of men with indications for PrEP based on state guidelines and levels of awareness, interest, and use of PrEP are presented for 1080 cisgender male respondents who completed the survey between January 1 and February 28, 2017. We conducted bivariate and multivariable logistic regression to identify factors associated with current PrEP use. To examine patterns of discontinuation, we conducted Cox proportional hazards regression and fit a Kaplan-Meier curve to reported data on time on PrEP. RESULTS: Eighty percent of respondents had heard of PrEP, 19% reported current use, and 36% of men who had never used PrEP wanted to start taking it. Among MSM for whom state guidelines recommend PrEP, 31% were taking it. In multivariable analysis, current PrEP use was associated with older age, higher education, and meeting indications for PrEP use. Our data suggest that 20% of PrEP users discontinue within 12 months, and men with lower educational attainment were more likely to discontinue. CONCLUSIONS: Despite high levels of use, there is significant unmet need for PrEP in Washington. Our experience indicates that Internet surveys are feasible and informative for monitoring PrEP use in MSM.

Hepatitis C Virus Potentially Transmitted by Opioid Drug Diversion from a Nurse - Washington, August 2017-March 2018.

During January 22-March 23, 2018, a local health department in Washington was notified of two patients who received a diagnosis of acute hepatitis C virus (HCV) infection. Neither patient had behavioral risk factors associated with HCV acquisition; however, both had received injectable narcotic (opioid) drugs from the same nurse during separate visits to an emergency department (ED) at a local hospital on December 6 and December 16, 2017. Investigation revealed that the nurse had accessed the automated drug dispensing system at a higher frequency than had other staff members, admitted diverting* patients' injectable narcotic and antihistamine drugs for personal use, and tested positive for HCV antibodies (anti-HCV) on March 19, 2018, but did not have quantifiable HCV RNA. Specimens from both patients were sent to CDC for genetic testing, and HCV viral variants analysis found a significant level of genetically similar HCV variants in both patients, indicating a common source of infection. Further investigation was conducted to confirm the infection source, identify other potentially exposed patients, and treat any new patients who received an HCV diagnosis. Monitoring frequency of access to drug dispensing systems can help identify staff members with abnormal dispensing patterns, including diversion activities (1). U.S. health care facilities are required to prevent, identify, and report any loss, diversion, or theft of controlled substances (2).

Washington state satellite HIV clinic program: a model for delivering highly effective decentralized care in under-resourced communities.

To improve access to high-quality HIV care in underserved regions of Western Washington (WA) State, we collaborated with the WA State Department of Health (DOH) and community partners to launch four satellite HIV clinics. Here, we describe this innovative clinical care model, present an estimate of costs, and evaluate patient care outcomes, including virologic suppression rates. To accomplish this, we assessed virologic suppression rates 12 months before and 12 months after the satellite clinics opened, comparing people living with HIV (PLWH) who enrolled in the satellite clinics versus all PLWH in the same regions who did not. We also determined virologic suppression rates in 2015 comparing satellite clinic versus non-satellite clinic patients and compared care quality indicators between the satellite clinics and the parent academic clinic. Results demonstrate that the change in virologic suppression rate 12 months before to 12 months after the satellite clinics opened was higher for patients who enrolled in the satellite clinics compared to all those in the same region who did not (18% versus 6%, p < 0.001). Virologic suppression in 2015 was significantly higher for satellite clinic than non-satellite clinic patients at three of four sites. Care quality indicators were met at a high level at the satellite clinics, comparable to the parent academic clinic. Overall, through community partnerships and WA DOH support, the satellite clinic program increased access to best practice HIV care and improved virologic suppression rates in difficult-to-reach areas. This model could be expanded to other regions with inadequate access to HIV practitioners, though financial support is necessary.

Prostate angiogenesis in development and inflammation.

BACKGROUND: Prostatic inflammation is an important factor in development and progression of BPH/LUTS. This study was performed to characterize the normal development and vascular anatomy of the mouse prostate and then examine, for the first time, the effects of prostatic inflammation on the prostate vasculature. METHODS: Adult mice were perfused with India ink to visualize the prostatic vascular anatomy. Immunostaining was performed on the E16.5 UGS and the P5, P20, and adult prostate to characterize vascular development. Uropathogenic E. coli 1677 was instilled transurethrally into adult male mice to induce prostate inflammation. RT-PCR and BrdU labeling was performed to assay anigogenic factor expression and endothelial proliferation, respectively. RESULTS: An artery on the ventral surface of the bladder trifurcates near the bladder neck to supply the prostate lobes and seminal vesicle. Development of the prostatic vascular system is associated with endothelial proliferation and robust expression of pro-angiogenic factors Pecam1, Tie1, Tek, Angpt1, Angpt2, Fgf2, Vegfa, Vegfc, and Figf. Bacterial-induced prostatic inflammation induced endothelial cell proliferation and increased vascular density but surprisingly decreased pro-angiogenic factor expression. CONCLUSIONS: The striking decrease in pro-angiogenic factor mRNA expression associated with endothelial proliferation and increased vascular density during inflammation suggests that endothelial response to injury is not a recapitulation of normal development and may be initiated and regulated by different regulatory mechanisms.

Language ENvironment Analysis Language and Autism Screen and the Child Development Inventory Social Subscale as a possible autism screen for children who are deaf or hard of hearing.

The Language ENvironment Analysis Language and Autism Screen (LLAS) is an automated vocal production analysis that has been shown to be a valid screener for autism in hearing children between the ages of 24 to 48 months of age. Although there is reportedly a higher incidence of autism among children who are deaf or hard of hearing, the diagnosis of autism is usually later than that in children with hearing. None of the traditional screening instruments have been used with children with hearing loss. Data about the utility of LLAS with children who are deaf or hard of hearing will be presented and discussed. Though more data will be needed, an LLAS at-risk flag in conjunction with the Social Quotient from the Child Development Inventory holds significant promise for a screen for children who are deaf or hard of hearing.

Preparation of deuterium-labeled biotransformation products of 2,4,6-trinitrotoluene.

Methods for the preparation of deuterium-labeled analogs to six prominent biotransformation products of the explosive 2,4,6-trinitrotoluene were developed. These are useful as reference standards for stable isotope dilution techniques and for solid state (2)H NMR spectroscopic studies. Although syntheses for most of the target compounds in protiated form had been reported in the past, most of those were found to be poorly suited for the preparation of the deuterated materials. Selective reduction of [(2)H5]trinitrotoluene furnished [(2)H5]-4,6-dinitro-2-hydroxylaminotoluene, [(2)H5]-2,6-dinitro-4-hydroxylaminotoluene, [(2)H5]-2-amino-4,6-dinitrotoluene, and [(2)H5]-4-amino-2,6-dinitrotoluene. The syntheses of [(2)H10]-2,2'-azo-4,4',6,6'-tetranitrotoluene and [(2)H10]-4,4'-azo-2,2',6,6'-tetranitrotoluene were accomplished by selective oxidation of [(2)H5]-2-amino-4,6-dinitrotoluene and [(2)H5]-4-amino-2,6-dinitrotoluene, respectively.

A multifaceted quality improvement intervention to improve management of alcohol withdrawal on a general medicine ward: impact on benzodiazepine use.

OBJECTIVE: To measure the effects of a quality improvement intervention on length of stay and benzodiazepine use among patients admitted for alcohol use disorder. METHODS: This retrospective cohort study was performed at the Salt Lake City Veterans Affairs Medical Center. Patients 18 years and older admitted to a general medical ward with a diagnosis of alcohol related disorders who were treated for alcohol withdrawal were included. The baseline cohort included patients admitted over 12 months. The post-intervention cohort included patients admitted over 12 months. Primary outcomes were total benzodiazepine dose and length of stay. Secondary outcomes included episodes of delirium tremens and seizures. RESULTS: Total benzodiazepine dose decreased significantly over the intervention period. Length of stay also decreased. No episodes of delirium tremens or seizures were observed. CONCLUSIONS: A quality improvement intervention directed at general medicine inpatients admitted for alcohol withdrawal was associated with reductions in total benzodiazepine administration and length of stay.

Deploying an Electronic Clinical Decision Support Tool for Diagnosis and Treatment of Pneumonia Into Rural and Critical Access Hospitals: Utilization, Effect on Processes of Care, and Clinician Satisfaction.

PURPOSE: Electronic clinical decision support (CDS) for treatment of community-acquired pneumonia (ePNa) is associated with improved guideline adherence and decreased mortality. How rural providers respond to CDS developed for urban hospitals could shed light on extending CDS to resource-limited settings. METHODS: ePNa was deployed into 10 rural and critical access hospital emergency departments (EDs) in Utah and Idaho in 2018. We reviewed pneumonia cases identified through ICD-10 codes after local deployment to measure ePNa utilization and guideline adherence. ED providers were surveyed to assess quantitative and qualitative aspects of satisfaction. FINDINGS: ePNa was used in 109/301 patients with pneumonia (36%, range 0%-67% across hospitals) and was associated with appropriate antibiotic selection (93% vs 65%, P < .001). Fifty percent of survey recipients responded, 87% were physicians, 87% were men, and the median ED experience was 10 years. Mean satisfaction with ePNa was 3.3 (range 1.7-4.8) on a 5-point Likert scale. Providers with a favorable opinion of ePNa were more likely to favor implementation of additional CDS (P = .005). Satisfaction was not associated with provider type, age, years of experience or experience with ePNa. Ninety percent of respondents provided qualitative feedback. The most common theme in high and low utilization hospitals was concern about usability. Compared to high utilization hospitals, low utilization hospitals more frequently identified concerns about adaptation for local needs. CONCLUSIONS: ePNa deployment to rural and critical access EDs was moderately successful and associated with improved antibiotic use. Concerns about usability and adapting ePNa for local use predominated the qualitative feedback.

Trends in Neisseria gonorrhoeae Incidence Among HIV-Negative and HIV-Positive Men in Washington State, 1996-2007.

OBJECTIVES: We assessed population-level trends in human immunodeficiency virus (HIV) and Neisseria gonorrhoeae co-infection among adult males in Washington State between 1996 and 2007. METHODS: Population-based categorical disease surveillance registries for gonorrhea and for HIV were electronically matched and merged at the record level and incidence rates were calculated for reported HIV-positive and presumed HIV-negative men. RESULTS: The incidence of gonorrhea infection increased significantly among both HIV-positive and presumed HIV-negative men from 1996 to 2005, and this trend has recently reversed for both groups. The annual incidence rate of gonorrhea among HIV-positive men was found to be higher in all years than among men presumed to be HIV-negative. CONCLUSIONS: Inequality in the burden of gonorrhea by HIV-infection status suggests continuing sexual risk-taking among HIV-positive men as well as possible barriers to diagnosis, treatment, and partner services. This inequality may also reflect significant differences in gonorrhea burden among men who have sex with men as well as by HIV status. Monitoring emergent secular trends in population-level HIV/sexually transmitted infection comorbidity through registry matching is an achievable strategy for developing an evidence base to inform program collaboration and service integration efforts aimed at providing more comprehensive disease prevention services.

A National Survey of Veterans Affairs Medical Centers' Cardiology Services.

A survey found that of cardiology services were widely available at facilities across the US Department of Veterans Affairs, but the types of services varied considerably based on facility complexity.

Youth-focused group mindfulness-based intervention in individuals with early psychosis: A randomized pilot feasibility study.

AIM: To assess the feasibility of a randomized pilot trial that evaluated the acceptability and potential clinical utility of the Mindfulness Ambassador Program (MAP), a unique, standardized 12-session facilitated group mindfulness-based intervention (MBI) for youth experiencing early psychosis. METHODS: Twenty-one patients of an early psychosis intervention program were randomized to receive MAP (n = 11) or treatment as usual (n = 10). Acceptability was measured by group attendance rate and client satisfaction; feasibility of the study design was measured by the recruitment and retention rate. The means, standard deviations, and 95% confidence intervals were described for outcomes of interest. RESULTS: MAP is associated with a high degree of acceptability and has beneficial effects for depression and fatigue. The randomized trial design is feasible. CONCLUSIONS: This study provides important pilot data supporting a larger randomized trial of effectiveness for MAP as a group MBI for early psychosis. Details of MAP and study limitations are discussed.

Decrease in Inpatient Telemetry Utilization Through a System-Wide Electronic Health Record Change and a Multifaceted Hospitalist Intervention.

BACKGROUND: Unnecessary telemetry monitoring contributes to healthcare waste. OBJECTIVE: To evaluate the impact of 2 interventions to reduce telemetry utilization. DESIGN, SETTING, PATIENTS: A 2-group retrospective, observational pre- to postintervention study of 35,871 nonintensive care unit (ICU) patients admitted to 1 academic medical center. INTERVENTION: On the hospitalist service, we implemented a telemetry reduction intervention including education, process change, routine feedback, and a financial incentive between January 2015 and June 2015. In July 2015, a system-wide change to the telemetry ordering process was introduced. MEASUREMENTS: The primary outcome was telemetry utilization, measured as the percentage of daily room charges for telemetry. Secondary outcomes were mortality, escalation of care, code event rate, and appropriateness of telemetry utilization. Generalized linear models were used to evaluate changes in outcomes while adjusting for patient factors. RESULTS: Among hospitalist service patients, telemetry utilization was reduced by 69% (95% confidence interval [CI], -72% to -64%; P < .001), whereas on other services the reduction was a less marked 22% (95% CI, -27% to -16%; P < .001). There were no significant increases in mortality, code event rates, or care escalation, and there was a trend toward improved utilization appropriateness. CONCLUSIONS: Although electronic telemetry ordering changes can produce decreases in hospital-wide telemetry monitoring, a multifaceted intervention may lead to an even larger decline in utilization rates. Whether these changes are durable cannot be ascertained from our study.

"Out of Care" HIV Case Investigations: A Collaborative Analysis Across 6 States in the Northwest US.

BACKGROUND: HIV care continuum estimates derived from laboratory surveillance typically assume that persons without recently reported CD4 count or viral load results are out of care. METHODS: We conducted a multistate project (Alaska, Idaho, Montana, Oregon, Washington, and Wyoming) to ascertain the status of HIV cases that appeared to be out of care during a 12-month period. We used laboratory surveillance to identify cases in all states but Idaho, where viral load reporting is not mandatory, requiring us to rely on clinic records. After complete investigation, we assigned each case one of the following dispositions: moved out of state, died, in HIV care, no evidence of HIV care, or data error. RESULTS: We identified 3866 cases with no CD4 count or viral load result in a ≥12-month period during 2012-2014, most (85%) of which were in Washington or Oregon. A median of 43% (range: 20%-67%) of cases investigated in each state had moved, 9% (0%-16%) had died, and 11% (8%-33%) were in care during the 12-month surveillance period. Only 28% of investigated cases in the region and a median of 30% (10%-57%) of investigated cases in each state had no evidence of care, migration, or death after investigation. CONCLUSIONS: Most persons living with HIV in the Northwest United States who appear to be out of care based on laboratory surveillance are not truly out of care. Our findings highlight the importance of improving state surveillance systems to ensure accurate care continuum estimates and guide Data to Care efforts.

Cognition and the prediction of functioning in patients with a first treated episode of psychosis: a prospective study.

Past research on the role of cognitive performance in predicting later psychosocial functioning for individuals with first treated episode of a psychotic disorder has yielded inconsistent results. Several factors have been suggested as determining the strength of any such relationship including the type of functioning measured, time of the cognitive assessment, covariates included and the use of global versus specific measures of cognitive functioning. In the current study, we examined the importance of these factors in a five year prospective study of individuals with first episode psychotic disorders. Just over 80% of the sample had a schizophrenia spectrum disorder. Cognitive assessments were carried out after initiation of treatment on 113 patients, and at one year for 79 patients. There was evidence that cognition predicted occupational functioning and use of a disability pension, but not a summary index of functioning or use of supervised housing, at follow-up. Overall I.Q. was a more consistent predictor than measures of specific cognitive functions, and there was evidence that cognition assessed after presentation for treatment, particularly after a year of treatment, was more predictive of later functioning than premorbid I.Q. Cognitive functioning, however, did not add to the prediction of outcomes beyond the level possible using past educational achievement or academic premorbid adjustment.

Enantioselective synthesis of imperanene via enzymatic asymmetrization of an intermediary 1,3-diol.

[reaction: see text] Using a chemoenzymatic synthetic strategy, (S)-imperanene and its (R)-enantiomer has been synthesized from vanillin in nine steps. The key step in the synthesis involves the use of Pseudomonas cepacia lipase (PS-30) to induce asymmetrization of the intermediary prochiral 1,3-diol in >97% ee.
