Paediatric chest compression performance improves via novel augmented-reality cardiopulmonary resuscitation feedback system: A mixed-methods pilot study in a simulation-based setting.

Aim: More than 20,000 children experience a cardiac arrest event each year in the United States. Most children do not survive. High-quality cardiopulmonary resuscitation (CPR) has been associated with improved outcomes yet adherence to guidelines is poor. We developed and tested an augmented reality head mounted display chest compression (CC) feedback system (AR-CPR) designed to provide real-time CC feedback and guidance. Methods: We conducted an unblinded randomized crossover simulation-based study to determine whether AR-CPR changes a user's CC performance. A convenience sample of healthcare providers who perform CC on children were included. Subjects performed three two-minute cycles of CC during a simulated 18-minute paediatric cardiac arrest. Subjects were randomized to utilize AR-CPR in the second or third CC cycle. After, subjects participated in a qualitative portion to inquire about their experience with AR-CPR and offer criticisms and suggestions for future development. Results: There were 34 subjects recruited. Sixteen subjects were randomly assigned to have AR-CPR in cycle two (Group A) and 18 subjects were randomized to have AR-CPR in cycle three (Group B). There were no differences between groups CC performance in cycle one (baseline). In cycle two, subjects in Group A had 73% (SD 18%) perfect CC epochs compared to 17% (SD 26%) in Group B (p < 0.001). Overall, subjects enjoyed using AR-CPR and felt it improved their CC performance. Conclusion: This novel AR-CPR feedback system showed significant CC performance change closer to CC guidelines. Numerous hardware, software, and user interface improvements were made during this pilot study.

Bed downtime: the novel use of a quality metric allows inpatient providers to improve patient flow from the emergency department.

BACKGROUND: Emergency department (ED) boarding time is associated with increased length of stay (LOS) and inpatient mortality. Despite the documented impact of ED boarding on inpatient outcomes, a disparity continues to exist between the attention paid to the issue by inpatient and ED providers. A perceived lack of high yield strategies to address ED boarding from the perspective of the inpatient provider may discourage involvement in improvement initiatives on the subject. As such, further work is needed to identify inpatient metrics and strategies to address patient flow problems, and which may improve ED boarding time. METHODS: After initial system analysis, our multidisciplinary quality improvement (QI) group defined the process time metric 'bed downtime'-the time from which a bed is vacated by a discharged patient to the time an ED patient is assigned to that bed. Using the Lean Sigma QI approach, this metric was targeted for improvement on the internal medicine hospitalist service at a tertiary care academic medical centre. INTERVENTIONS: Interventions included improving inpatient provider awareness of the problem, real-time provider notification of empty beds, a weekly retrospective emailed performance dashboard and the creation of a guideline document for admission procedures. RESULTS: This package of interventions was associated with a 125 min reduction in mean bed downtime for incoming ED patients (254 min to 129 min) admitted to the intervention unit. CONCLUSION: Use of the bed downtime metric as a QI target was associated with marked improvements in process time during our project. The use of this metric may enhance the ability of inpatient providers to participate in QI efforts to improve patient flow from the ED. Further study is needed to determine if use of the metric may be effective at reducing boarding time without requiring alterations to LOS or discharge patterns.

Comparison of Ultrasound-Guided Vs Traditional Arterial Cannulation by Emergency Medicine Residents.

INTRODUCTION: We sought to determine whether ultrasound-guided arterial cannulation (USGAC) is more successful than traditional radial artery cannulation (AC) as performed by emergency medicine (EM) residents with standard ultrasound training. METHODS: We identified 60 patients age 18 years or older at a tertiary care, urban academic emergency department who required radial AC for either continuous blood pressure monitoring or frequent blood draws. Patients were randomized to receive radial AC via either USGAC or traditional AC. If there were three unsuccessful attempts, patients were crossed over to the alternative technique. All EM residents underwent standardized, general ultrasound training. RESULTS: The USGAC group required fewer attempts as compared to the traditional AC group (mean 1.3 and 2.0, respectively; p<0.001); 29 out of 30 (96%) successful radial arterial lines were placed using USGAC, whereas 14 out of 30 (47%) successful lines were placed using traditional AC (p<0.001). There was no significant difference in length of procedure or complication rate between the two groups. There was no difference in provider experience with respect to USGAC vs traditional AC. CONCLUSION: EM residents were more successful and had fewer cannulation attempts with USGAC when compared to traditional AC after standard, intern-level ultrasound training.

Peroral endoscopic myotomy: anterior versus posterior approach: a randomized single-blinded clinical trial.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) has become the mainstay for the treatment of achalasia at many institutions around the world since its inception in 2008. POEM can be performed using either the anterior or posterior approach. The primary aim of this study was to compare the efficacy of the anterior and posterior approaches at 1 year after POEM. METHODS: This is a single-blinded, randomized, noninferiority international clinical trial. Eligible participants were adult patients with a confirmed diagnosis of achalasia via high-resolution esophageal manometry. Patients were randomly allocated with a 1:1 ratio to receive POEM with anterior or posterior approach. The primary aim was to compare the rate of clinical success (Eckardt score <3) of anterior and posterior approaches at 1 year. RESULTS: One hundred fifty patients were randomized to receive either anterior (n = 73) or posterior (n = 77) POEM. One hundred forty-eight patients received the POEM treatment, and 138 patients completed the 1-year follow-up and were included in the primary efficacy analysis. Technical success was achieved in 71 patients (97.3%) in the anterior group versus 77 patients (100%) in the posterior group (P = .23). The median (interquartile range) length of hospital stay after the procedure was 2 (1-3) days for both groups. Adverse events occurred in 15 patients (10%), 8 patients (11%) in the anterior group and 7 patients (9%) in the posterior group (P = .703). Clinical success was achieved in 90% of patients in the anterior group and 89% of patients in the posterior group. Abnormal esophageal acid exposure was detected in 29 of 59 patients (49%) and 25 of 60 patients (42%) in the anterior and posterior groups, respectively (P = .67). GERD questionnaire scores were also not significantly different between the study groups. In both groups, quality of life improved after POEM for all 36-Item Short-Form Health Survey measures and was similar between both groups. CONCLUSIONS: Posterior myotomy during POEM was not inferior to anterior myotomy in terms of efficacy and safety in the treatment of patients with achalasia.

Bubble continuous positive airway pressure for children with high-risk conditions and severe pneumonia in Malawi: an open label, randomised, controlled trial.

BACKGROUND: Pneumonia is the leading cause of death among children globally. Most pneumonia deaths in low-income and middle-income countries (LMICs) occur among children with HIV infection or exposure, severe malnutrition, or hypoxaemia despite antibiotics and oxygen. Non-invasive bubble continuous positive airway pressure (bCPAP) is considered a safe ventilation modality that might improve child pneumonia survival. bCPAP outcomes for high-risk African children with severe pneumonia are unknown. Since most child pneumonia hospitalisations in Africa occur in non-tertiary district hospitals without daily physician oversight, we aimed to examine whether bCPAP improves severe pneumonia mortality in such settings. METHODS: This open-label, randomised, controlled trial was done in the general paediatric ward of Salima District Hospital, Malawi. We enrolled children aged 1-59 months old with WHO-defined severe pneumonia and either HIV infection or exposure, severe malnutrition, or an oxygen saturation of less than 90%. Children were randomly assigned 1:1 to low-flow nasal cannula oxygen or nasal bCPAP. Non-physicians administered care; the primary outcome was hospital survival. Primary analyses were by intention-to-treat and interim and adverse events analyses per protocol. This trial is registered with ClinicalTrials.gov, number NCT02484183, and is closed. FINDINGS: We screened 1712 children for eligibility between June 23, 2015, and March 21, 2018. The data safety and monitoring board stopped the trial for futility after 644 of the intended 900 participants were enrolled. 323 children were randomly assigned to oxygen and 321 to bCPAP. 35 (11%) of 323 children who received oxygen died in hospital, as did 53 (17%) of 321 who received bCPAP (relative risk 1·52; 95% CI 1·02-2·27; p=0·036). 13 oxygen and 17 bCPAP patients lacked hospital outcomes and were considered lost to follow-up. Suspected adverse events related to treatment occurred in 11 (3%) of 321 children receiving bCPAP and 1 (<1%) of 323 children receiving oxygen. Four bCPAP and one oxygen group deaths were classified as probable aspiration episodes, one bCPAP death as probable pneumothorax, and six non-death bCPAP events included skin breakdown around the nares. INTERPRETATION: bCPAP treatment in a paediatric ward without daily physician supervision did not reduce hospital mortality among high-risk Malawian children with severe pneumonia, compared with oxygen. The use of bCPAP within certain patient populations and non-intensive care settings might carry risk that was not previously recognised. bCPAP in LMICs needs further evaluation before wider implementation for child pneumonia care.

HIV viral suppression and geospatial patterns of HIV antiretroviral therapy treatment facility use in Rakai, Uganda.

OBJECTIVE: To assess geospatial patterns of HIV antiretroviral therapy (ART) treatment facility use and whether they were impacted by viral load suppression. METHODS: We extracted data on the location and type of care services utilized by HIV-positive persons accessing ART between February 2015 and September 2016 from the Rakai Community Cohort Study in Uganda. The distance from Rakai Community Cohort Study households to facilities offering ART was calculated using the open street map road network. Modified Poisson regression was used to identify predictors of distance traveled and, for those traveling beyond their nearest facility, the probability of accessing services from a tertiary care facility. RESULTS: In total, 1554 HIV-positive participants were identified, of whom 68% had initiated ART. The median distance from households to the nearest ART facility was 3.10 km (interquartile range, 1.65-5.05), but the median distance traveled was 5.26 km (interquartile range, 3.00-10.03, P < 0.001) and 57% of individuals travelled further than their nearest facility for ART. Those with higher education and wealth were more likely to travel further. In total, 93% of persons on ART were virally suppressed, and there was no difference in the distance traveled to an ART facility between those with suppressed and unsuppressed viral loads (5.26 vs. 5.27 km, P = 0.650). CONCLUSION: Distance traveled to HIV clinics was increased with higher socioeconomic status, suggesting that wealthier individuals exercise greater choice. However, distance traveled did not vary by those who were or were not virally suppressed.

The validity of self-reported antiretroviral use in persons living with HIV: a population-based study.

OBJECTIVE: To assess the validity of self-reported antiretroviral therapy use (ART) using population-based cohort data. METHODS: Self-reported ART use and nonuse was compared with a validated laboratory assay in 557 HIV-positive participants in the Rakai Community Cohort Study surveyed between September and December 2011 in Rakai, Uganda. The study population included participants from seven communities, including one fishing community with high HIV prevalence (∼41%). ART use was assayed using liquid chromatography-tandem mass spectrometry, which detects 20 antiretroviral drugs. HIV viral load measurements were also obtained. Individuals with at least two antiretroviral drugs detected were considered to be using ART. RESULTS: One hundred and fifty-three (27%) participants self-reported ART use of whom 148 (97%) had at least two antiretroviral drugs detected. There were at least two antiretroviral drugs detected in 11% (n = 44/404) of individuals with no self-reported ART use. Overall, the specificity of self-reported ART use was 99% (95% CI 97-100%) and the sensitivity was 77% (70-83%). Positive and negative predictive values were 97% (95% CI 93-99%) and 89% (95% CI 86-92%), respectively. Nondisclosure of ART use was significantly more common in younger persons (<30 years) and among those in trading occupations. CONCLUSION: Self-reported ART use has high specificity and moderate sensitivity providing reasonable, but conservative estimates of population-based ART use. There is more under-reporting of ART use among younger persons and traders suggesting a need for more research on barriers to self-reporting of ART use in these sub-groups.

Human immunodeficiency virus care cascade among sub-populations in Rakai, Uganda: an observational study.

INTRODUCTION: To assess progress towards the UNAIDS 90-90-90 initiative targets, we examined the HIV care cascade in the population-based Rakai Community Cohort Study (RCCS) in rural Uganda and examined differences between sub-groups. METHODS: Self-reports and clinical records were used to assess the proportion achieving each stage in the cascade. Statistical inference based on a χ2 test for categorical variables and modified Poisson regression were used to estimate prevalence risk ratios (PRRs) and 95% confidence intervals (CI) for enrolment into care and initiating antiretroviral therapy (ART). RESULTS: From September 2013 through December 2015, 3,666 HIV-positive participants were identified in the RCCS. As of December 2015, 98% had received HIV Counseling and Testing (HCT), 74% were enrolled in HIV care, and 63% had initiated ART of whom 92% were virally suppressed after 12 months on ART. Engagement in care was lower among men than women (enrolment in care: adjPRR 0.84, 95% CI 0.77-0.91; ART initiation: adjPRR 0.75, 95% CI 0.69-0.82), persons aged 15-24 compared to those aged 30-39 (enrolment: adjPRR 0.72, 95% CI 0.63-0.82; ART: adjPRR 0.69, 95%CI 0.60-0.80), unmarried persons (enrolment: adjPRR 0.84, 95% CI 0.71-0.99; ART adjPRR 0.80, 95% CI 0.66-0.95), and new in-migrants (enrolment: adjPRR 0.75, 95% CI 0.67-0.83; ART: adjPRR 0.76, 95% CI 0.67-0.85). This cohort achieved 98-65-92 towards the UNAIDS "90-90-90" targets with an estimated 58% of the entire HIV-positive RCCS population virally suppressed. CONCLUSIONS: This cohort achieved over 90% in both HCT and viral suppression among ART users, but only 65% in initiating ART, likely due to both an ART eligibility criterion of <500 CD4 cells/mL and suboptimal entry into care among men, younger individuals, and in-migrants. Interventions are needed to promote enrolment in HIV care, particular for hard-to-reach sub-populations.

Effectiveness of peer support on care engagement and preventive care intervention utilization among pre-antiretroviral therapy, HIV-infected adults in Rakai, Uganda: a randomized trial.

442 pre-ART, HIV-infected adults were randomized to peer support consisting of structured home visits to promote clinic attendance and preventive care intervention use or standard of care. At baseline, 62 % reported previously visiting an HIV clinic, 45 % reported taking cotrimoxazole prophylaxis, and 31 % were "care-naïve" (no previous clinic visit and not on cotrimoxazole). After 1 year, intervention participants were more likely to report being in care (92 vs 84 %; PRR 1.09, p = 0.039), on cotrimoxazole (89 vs 81 %; PRR 1.10, p = 0.047), and safe water vessel adherence (23 vs 14 %; PRR 1.64, p = 0.024). The effect was observed only among care-naïve participants (n = 139) with 83 % intervention versus 56 % controls reporting being in HIV care (PRR 1.47, p = 0.006), 78 versus 58 % on cotrimoxazole (PRR 1.35, p = 0.04), and 20 versus 4 % safe water vessel adherence (PRR 5.78, p = 0.017). Peer support may be an effective intervention to facilitate pre-ART care compliance in this important population.

Religiosity and HIV-related drug risk behavior: a multidimensional assessment of individuals from communities with high rates of drug use.

We examined the relationship between religiosity and HIV-related drug risk behavior among individuals from communities with high rates of drug use who participated in the SHIELD (Self-Help in Eliminating Life-Threatening Disease) study. This analysis examined the dimensions of religious ideation, religious participation, and religious support separately to further understand the relationship with risk taking. Results indicate that greater religious participation appeared to be the dimension most closely associated with drug behaviors. Specifically, we found that those with greater religious participation are significantly less likely to report recent opiates or cocaine use; injection drug use; crack use; and needle, cotton or cooker sharing. Future work to understand the nature of these associations will assist in the development of interventions in communities with high rates of drug use.

HIV risk-related behaviors in the United States household population aged 15-44 years: data from the National Survey of Family Growth, 2002 and 2006-2010.

OBJECTIVE: This report presents national estimates of selected HIV risk-related behaviors among men and women 15-44 years of age in the United States, based on the 2006-2010 National Survey of Family Growth (NSFG). Data from the 2006-2010 NSFG are compared with data from the 2002 NSFG. METHODS: Data for 2006-2010 were collected through in-person interviews with a national sample of 22,682 men and women aged 15-44 years in the household population of the United States. The measures presented in this report were collected using audio computer-assisted self-interviewing (ACASI), in which the respondent enters his or her own answers into the computer without telling them to an interviewer. The response rate for the 2006-2010 NSFG was 77%, 78% for women and 75% for men. HIV risk-related behavioral measures examined in this report include sexual risk, drug risk, and recent STD treatment. RESULTS: Approximately 10% of men and 8% of women in 2006-2010 reported at least one of the HIV risk-related behavioral measures examined in this report, representing 6.5 million men and 4.9 million women in the general U.S. household population. This represents a decline from the 13% of men and 11% of women who reported one or more of these measures in 2002. This decline appears to be due to a decrease in sexual risk behaviors reported in 2006-2010, however further analysis as well as comparisons with other household surveys are needed to fully understand and describe trends over time. Significant variations were seen by demographic and socioeconomic characteristics including age, race and Hispanic origin, sex, education, and poverty level income. Among men, those with recent prison experience were more likely than other men to report one or more HIV risk-related behaviors in the past year.

Infectious disease prevalence in Los Angeles county--a comparison to national estimates, 1999-2004 birth rates for U.S. teenagers reach historic lows for all age and ethnic groups.

This is the first time seroprevalence of antibody to these nine infectious diseases have been available for LAC. Differences in the race and ethnicity distribution of the United States and LAC were observed. Because disease prevalence varies by race and ethnicity, in some instances these demographic differences affected the population differences seen between the United States and LAC in the seroprevalence of the infectious diseases reported in this study. Seroprevalence for HAV was higher in LAC as compared with the United States among the total population and among the Mexican-American population. California is 1 of 11 states in which routine vaccination of children was recommended in 1999 by the Advisory Committee on Immunization Practices (ACIP) because mean incidence rates in these states were at least twice the national mean from 1987­1997 (9). Seroprevalence to CMV and T. gondii have been shown to be higher among Mexican-American persons then other race and ethnicity groups (1,3). The higher seropositivity for CMV and T. gondii among persons from LAC is due to the higher proportion of Mexican-American persons in the LAC population. No differences in seropositivity were observed when comparing Mexican-American persons in the United States and LAC for these two outcomes. No significant differences in seroprevalence between the United States and LAC were seen for measles, mumps, rubella, varicella, HSV-1, and HSV-2. Estimates of seropositivity from immunization or disease for LAC may assist in policy development, program planning, and measuring health disparities.

HIV testing in the U.S. household population aged 15-44: data from the National Survey of Family Growth, 2006-2010.

OBJECTIVES: This report presents nationally representative estimates and trends for human immunodeficiency virus (HIV) testing among the U.S. household population aged 15-44. Data are presented for lifetime experience with HIV testing and HIV testing in the past year, including testing done as part of prenatal care. METHODS: Data for this report come from the 2006-2010 National Survey of Family Growth (NSFG), consisting of 22,682 interviews with men and women aged 15-44, conducted from June 2006 through June 2010. The overall response rate for the 2006-2010 NSFG was 77%: 78% for women and 75% for men. RESULTS: Among U.S. women aged 15-44, the percentage ever tested for HIV outside of blood donation increased significantly from 35% in 1995 to 55% in 2002, and to 59% in 2006-2010. Among men aged 15-44, the percentage ever tested outside blood donation fell from 47% in 2002 to 42% in 2006-2010. Within gender groups in 2006-2010, the proportions ever tested for HIV outside of blood donation were similar for Hispanic and non-Hispanic white persons: roughly 6 out of 10 among women and 4 out of 10 among men. However, a higher percentage of non-Hispanic black women (75%) and non-Hispanic black men (61%) had ever been tested for HIV outside of blood donation. Based on 2006-2010 data, 21% of women were tested for HIV within the 12 months prior to interview, compared with 13% of men. While NSFG data cannot ascertain the temporal sequencing of risk-related behaviors and HIV testing, the data indicate that testing within the past year occurs more often among individuals reporting potential HIV risk-related behaviors.
