Supervised Exercise Therapy for Symptomatic Peripheral Artery Disease: A REVIEW OF CURRENT EXPERIENCE AND PRACTICE-BASED RECOMMENDATIONS.

PURPOSE: This review encompasses several practical components of supervised exercise therapy (SET) for patients with claudication including referral, exercise training, and billing issues. Real-life SET session examples are also provided. SET was approved for reimbursement by the Centers for Medicare & Medicaid Services (CMS) in 2017, and there is continual growth of programs offering SET and in participation. The purpose of this review is to provide useful information for the clinical exercise professionals working with these patients. REVIEW METHODS: The 2016 ACC/AHA Guideline on the Management of Patients With Lower Extremity Peripheral Artery Disease (PAD) provided a class I (highest level) recommendation for the use of SET in those with symptomatic PAD. Since there has been much growth in the literature about the utility of SET, the literature was reviewed (PubMed) to provide information for this article. Topics reviewed include the benefits of exercise training, exercise prescription, billing, referral and participation, and best practices. SUMMARY: SET should be offered to all patients with symptomatic PAD who are not at risk of acute limb ischemia. For optimal results, SET should be implemented several times per week and in a progressive process to increase exercise intensity as tolerated. For best results, programs should recommend patients supplement SET with home exercise. Considerations for utilizing reimbursed sessions should also be discussed because patients have a maximum of 72 sessions/lifetime. Referral practices need refinement, and participation rates remain extremely low and may be influenced by demographics. Research on best practices and home or hybrid training must continue to address issues related to common enrollment and participation barriers. CONDENSED ABSTRACT: Supervised exercise training (SET) for symptomatic peripheral artery disease is a class IA recommendation and reimbursable by most insurances. Improvements in walking performance can be dramatic. However, referral and participation in SET remain very low and thus SET is vastly underutilized.

Initial characterization of print awareness in unhoused children.

This study provides an initial understanding of print awareness, a foundational literacy skill, in a group of 12 unhoused children at two shelters in a large urban setting. Children ranged in age from 4;1 to 8;0, representing grades associated with learning to read (i.e., pre-kindergarten to second grade). Findings indicate that the majority of children in this sample were significantly delayed in their acquisition of print awareness skills. Caregivers were surveyed regarding their beliefs about supporting literacy development and what would be beneficial for helping them in this area. Responses indicated that almost all caregivers believed that some literacy development should occur outside of the school setting and that it would be helpful if they (the caregivers) were taught both what skills to teach and how to teach them.

The relative contributions of adiposity and activity levels to physical performance in children with excess weight.

OBJECTIVE: This study examined predictors of physical performance, a key aspect of quality of life, in children with excess weight. METHODS: Participants were 269 children aged 6-12 years with a body mass index above the 85th percentile. Children completed a standardized physical performance task capturing lower extremity strength, balance, and gait speed. Height, weight, and waist circumference were objectively measured, and daily moderate-vigorous physical activity (min/day) and sedentary time (% of day) were assessed with a 7-day accelerometer protocol. RESULTS: Physical performance task completion averaged 15.0 (SD = 2.5) seconds. Children with higher body mass index z-scores and waist circumferences had significantly longer task completion times. The task took 1.8 additional seconds per 1.0 body mass index z-score (p < .001), and 1.2 additional seconds for every 20 cm higher waist circumference (p < .001). Daily moderate-vigorous physical activity and sedentary time were unrelated to physical performance, and did not moderate its associations with the adiposity measures. CONCLUSION: Among children with excess weight, physical performance declines with increasing levels of total and central adiposity. Daily activity levels do not moderate this association. Interventions that directly target weight reduction would likely yield the greatest improvement in physical performance in children with overweight or obesity.

Attenuated efficacy of pediatric obesity treatment during the COVID-19 pandemic.

OBJECTIVE: This study examined whether the efficacy of a standard-of-care pediatric obesity treatment was affected by the COVID-19 pandemic. METHODS: Analyses leveraged data from an ongoing pediatric obesity treatment trial involving 230 lower-income, urban children aged 6 to 12 years. Mixed-effects regression models compared children who participated in a 12-month weight-management intervention before versus during the COVID-19 pandemic on change from baseline in BMI z score (ΔzBMI) at 3, 6, 9, and 12 months. RESULTS: The observed pattern of ΔzBMI was significantly different before versus during the pandemic (χ2 = 22.73, p < 0.0001). Children treated before the pandemic maintained an average weight loss of -0.06 ΔzBMI at 12 months, whereas children treated during the pandemic steadily gained weight over time, averaging a net gain of 0.11 ΔzBMI at 12 months (χ2 = 34.99, p < 0.0001). Treatment session completion did not differ before versus during the pandemic (60.4% vs. 55.7%, respectively; p = 0.30) or account for differences in ΔzBMI. CONCLUSIONS: Similar reductions in intervention efficacy may be anticipated in other pediatric obesity treatment trials conducted during the COVID-19 pandemic. Many families that have struggled with managing their child's weight during this period may need encouragement to continue engaging in structured weight management as society renormalizes.

A Review of the Design and Implementation of a Hybrid Cardiac Rehabilitation Program: AN EXPANDING OPPORTUNITY FOR OPTIMIZING CARDIOVASCULAR CARE.

PURPOSE: This review describes the considerations for the design and implementation of a hybrid cardiac rehabilitation (HYCR) program, a patient-individualized combination of facility-based cardiac rehabilitation (FBCR) with virtual cardiac rehabilitation (CR) and/or remote CR. REVIEW METHODS: To help meet the goal of the Millions Hearts Initiative to increase CR participation to 70% by 2022, a targeted review of the literature was conducted to identify studies pertinent to the practical design and implementation of an HYCR program. Areas focused upon included the current use of HYCR, exercise programming considerations (eligibility and safety, exercise prescription, and patient monitoring), program assessments and outcomes, patient education, step-by-step instructions for billing and insurance reimbursement, patient and provider engagement strategies, and special considerations. SUMMARY: A FBCR is the first choice for patient participation in CR, as it is supported by an extensive evidence base demonstrating effectiveness in decreasing cardiac and overall mortality, as well as improving functional capacity and quality of life. However, to attain the CR participation rate goal of 70% set by the Million Hearts Initiative, CR programming will need to be expanded beyond the confines of FBCR. In particular, HYCR programs will be necessary to supplement FBCR and will be particularly useful for the many patients with geographic or work-related barriers to participation in an FBCR program. Research is ongoing and needed to develop optimal programming for HYCR.

Effectiveness of Modalities to Teach Evidence Based Medicine to Pediatric Clerkship Students: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effectiveness of a traditional didactic session (TDS) as compared to a self-paced, interactive, multimedia module (SPM) on the application of evidence-based medicine (EBM) skills among medical students during their inpatient pediatric rotation. METHODS: We conducted a randomized controlled trial from June, 2017 to June, 2018 at a quaternary care children's hospital. Students were randomized to TDS or SPM during each 2-week block. All students completed a critical appraisal tool (CAT) of evidence related to a clinical question in a standardized appraisal form and self-reflected about the EBM process. The primary outcome was the numeric score of the CAT derived by using the validated Fresno tool. Secondary outcomes of knowledge, attitudes, confidence, and self-reported behaviors related to EBM were measured using validated surveys. Statistical analysis was performed using Student's t test for CAT scores and mixed-model procedure (PROC MIXED), with subject as random effect and time as repeated measure for the secondary outcomes. RESULTS: One hundred twenty-seven clerkship students were included. Overall, there was no significant difference in mean CAT scores for TDS (n = 59) versus SPM (n = 66) groups (90.3 vs 92.0, P = .65). There were no significant differences between SPM and TDS groups for knowledge (P = .66), attitudes (P = .97), confidence (P  = .55), and accessing evidence (P = .27). Both groups showed significant gains in knowledge, attitudes, confidence, and accessing evidence from baseline to postcourse. Improvements in knowledge and confidence were sustained at 3-months. CONCLUSION: A SPM learning module is as effective as a TDS module for application of EBM concepts and knowledge to patient care.

Clinical Predictors for Abnormal Renal Bladder Ultrasound in Hospitalized Young Children With a First Febrile Urinary Tract Infection.

BACKGROUND: Physicians often obtain a routine renal bladder ultrasound (RBUS) for young children with a first febrile urinary tract infection (UTI). However, few children are diagnosed with serious anatomic anomalies, and opportunity may exist to take a focused approach to ultrasonography. We aimed to identify characteristics of the child, prenatal ultrasound (PNUS), and illness that could be used to predict an abnormal RBUS and measure the impact of RBUS on management. METHODS: We conducted a single-center prospective cohort study of hospitalized children 0 to 24 months of age with a first febrile UTI from October 1, 2016, to December 23, 2018. Independent variables included characteristics of the child, PNUS, and illness. The primary outcome, abnormal RBUS, was defined through consensus of a multidisciplinary team on the severity of ultrasound findings important to identify during a first UTI. RESULTS: A total of 211 children were included; the median age was 1.0 month (interquartile range 0-2), and 55% were uncircumcised boys. All mothers had a PNUS with 10% being abnormal. Escherichia coli was the pathogen in 85% of UTIs, 20% (n = 39 of 197) had bacteremia, and 7% required intensive care. Abnormal RBUS was found in 36% (n = 76 of 211) of children; of these, 47% (n = 36 of 76) had moderately severe findings and 53% (n = 40 of 76) had severe findings. No significant difference in clinical characteristics was seen among children with and without an abnormal RBUS. One child had Foley catheter placement, and 33% received voiding cystourethrograms, 15% antibiotic prophylaxis, and 16% subspecialty referrals. CONCLUSIONS: No clinical predictors were identified to support a focused approach to RBUS examinations. Future studies should investigate the optimal timing for RBUS.

Variations in Care for Breastfed Infants Admitted to US Children's Hospitals: A Multicenter Survey of Inpatient Providers.

BACKGROUND: Studies have revealed an association between hospitalization of breastfed infants and weaning posthospitalization. It is unknown what steps inpatient providers at children's hospitals are currently taking to support breastfeeding mothers of hospitalized infants, their comfort providing breastfeeding counseling, and what training they receive. METHODS: We conducted a multicenter survey study of pediatric providers who care for infants hospitalized at 3 urban, tertiary-care children's hospitals over a 12-month period. A convenience sample of nurses, residents, and attending physicians agreed to participate. Participants completed a 24-question questionnaire addressing provider practices, comfort with breastfeeding counseling, and previous breastfeeding education. Data were summarized as medians (interquartile ranges) and frequencies (percentages). Kruskal-Wallis and χ2 tests were used to compare between provider types. RESULTS: A total of 361 out of 1097 (33%) eligible providers completed the survey: 133 (21%) nurses, 166 (45%) residents, and 62 (63%) attending physicians. Provider practices varied by provider type. We observed a general trend that providers do not routinely review breastfeeding techniques, directly observe feeds, or use standardized breastfeeding assessment tools. Residents and attending physicians were more likely than nurses to feel comfortable with breastfeeding counseling (P = .02). Residents were more likely than nurses and attending physicians to have received breastfeeding education in the last 3 years (P < .001). CONCLUSIONS: Practices, comfort, and previous education varied by provider type. There was a general pattern that providers do not routinely perform certain practices. Further studies are needed to determine if inpatient provider practices affect weaning posthospitalization and if inpatient quality improvement initiatives will help mothers continue breastfeeding posthospitalization.

Trawl ban in a heavily exploited marine environment: Responses in population dynamics of four stomatopod species.

Intensive trawling activities in Hong Kong waters have seriously depleted fishery resources and damaged marine benthic habitats over the last four decades. To minimize further destruction and rehabilitate fishery resources, the Hong Kong Government implemented a permanent territory-wide trawling closure on 31 December 2012. Such a trawl ban creates a unique opportunity to investigate recoveries in ecosystem structure and function following a major shift in disturbance regime by removing impacts from a major gear. This study was designed to test the hypothesis that dominant predatory mantis shrimps, including Harpiosquilla harpax, Miyakella nepa, Oratosquillina interrupta, and Oratosquilla oratoria would show signs of recovery following the trawl ban. Their population dynamics were investigated before and after the trawl ban. The results showed that their mean weight, mean carapace length and proportion of large-sized individuals increased significantly 3.5 years after the trawl ban, whilst their abundance, biomass and maximum length remained unchanged. This study suggests that the stomatopod assemblage in the human-dominated Hong Kong waters shows some initial signs of possible recovery following the trawl ban but also highlights the complexity of implementing fishery management and detecting changes resulted from management measures in a heavily urbanized seascape where many biotic and abiotic factors can influence their population dynamics.

The Chronic Care Model to Improve Management of Childhood Obesity.

One-third of children in the United States are overweight or obese. Comorbidities continue into adulthood if a healthy weight is not established. While expert guidelines for management of this condition are recognized, provider adherence to guidelines is lacking. The purpose of this quality improvement project was to evaluate the effectiveness of the chronic care model (CCM) on improving primary care provider identification, prevention, and management of childhood overweight and obesity. A pre- and postintervention chart audit was completed to evaluate documentation of 20 assessment measures included in expert guidelines. A chi-square analysis was conducted to assess differences. Statistically significant improvements were found in documentation of parental obesity, family medical history, sleep assessment, endocrine assessment, and weight classification as a diagnosis. Use of the CCM had a positive impact on provider adherence to expert guidelines. Furthermore, not all aspects of the CCM must be used to see statistically significant improvements.

Increasing Cardiac Rehabilitation Participation From 20% to 70%: A Road Map From the Million Hearts Cardiac Rehabilitation Collaborative.

The primary aim of the Million Hearts initiative is to prevent 1 million cardiovascular events over 5 years. Concordant with the Million Hearts' focus on achieving more than 70% performance in the "ABCS" of aspirin for those at risk, blood pressure control, cholesterol management, and smoking cessation, we outline the cardiovascular events that would be prevented and a road map to achieve more than 70% participation in cardiac rehabilitation (CR)/secondary prevention programs by the year 2022. Cardiac rehabilitation is a class Ia recommendation of the American Heart Association and the American College of Cardiology after myocardial infarction or coronary revascularization, promotes the ABCS along with lifestyle counseling and exercise, and is associated with decreased total mortality, cardiac mortality, and rehospitalizations. However, current participation rates for CR in the United States generally range from only 20% to 30%. This road map focuses on interventions, such as electronic medical record-based prompts and staffing liaisons that increase referrals of appropriate patients to CR, increase enrollment of appropriate individuals into CR, and increase adherence to longer-term CR. We also calculate that increasing CR participation from 20% to 70% would save 25,000 lives and prevent 180,000 hospitalizations annually in the United States.

Identification, Prevention, and Management of Childhood Overweight and Obesity in a Pediatric Primary Care Center.

Background In the United States, overweight/obesity among youth has reached epidemic proportions. The purpose of this project was to (1) examine primary care provider adherence to American Academy of Pediatrics guidelines; (2) compare adherence based on patients' weight classification, age, race, and gender; and (3) identify areas for improvement in health care delivery. Methods A retrospective chart audit and feedback quality improvement project was conducted with a stratified random sample of 175 charts of 6- to 19-year-olds seen for well-child visits. Frequencies of provider adherence were reported. χ(2) Analyses of weight classification, age, race, or gender influence on adherence was calculated. Results After discussion with the primary care providers, 5 areas were identified as priorities for change (diagnosis based on BMI, parental history of obesity, sleep assessment, endocrine assessment, and attendance of patients at the follow-up visit). Conclusion Cost-efficient, feasible strategies to improve provider adherence to recommendations for identification, prevention and management of childhood overweight and obesity were identified.

Reliability of abstracting performance measures: results of the cardiac rehabilitation referral and reliability (CR3) project.

BACKGROUND: Assessment of the reliability of performance measure (PM) abstraction is an important step in PM validation. Reliability has not been previously assessed for abstracting PMs for the referral of patients to cardiac rehabilitation (CR) and secondary prevention (SP) programs. To help validate these PMs, we carried out a multicenter assessment of their reliability. METHODS: Hospitals and clinical practices from around the United States were invited to participate in the Cardiac Rehabilitation Referral Reliability (CR3) Project. Twenty-nine hospitals and 23 outpatient centers expressed interest in participating. Seven hospitals and 6 outpatient centers met participation criteria and submitted completed data. Site coordinators identified 35 patients whose charts were reviewed by 2 site abstractors twice, 1 week apart. Percent agreement and the Cohen κ statistic were used to describe intra- and interabstractor reliability for patient eligibility for CR/SP, patient exceptions for CR/SP referral, and documented referral to CR/SP. RESULTS: Results were obtained from within-site data, as well as from pooled data of all inpatient and all outpatient sites. We found that intra-abstractor reliability reflected excellent repeatability (≥ 90% agreement; κ ≥ 0.75) for ratings of CR/SP eligibility, exceptions, and referral, both from pooled and site-specific analyses of inpatient and outpatient data. Similarly, the interabstractor agreement from pooled analysis ranged from good to excellent for the 3 items, although with slightly lower measures of reliability. CONCLUSIONS: Abstraction of PMs for CR/SP referral has high reliability, supporting the use of these PMs in quality improvement initiatives aimed at increasing CR/SP delivery to patients with cardiovascular disease.

Medical director responsibilities for outpatient cardiac rehabilitation/secondary prevention programs: 2012 update: a statement for health care professionals from the American Association of Cardiovascular and Pulmonary Rehabilitation and the American Heart Association.

Medical directors of cardiac rehabilitation/secondary prevention (CR/SP) programs are responsible for the safe and effective delivery of high-quality CR/SP services to eligible patients. Yet, the training and resources for CR/SP medical directors are limited. As a result, there appears to be considerable variability throughout CR/SP programs in the United States in the roles, responsibilities, and engagement of CR/SP medical directors. Since the publication of the 2005 scientific statement from the American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation regarding medical director responsibilities for outpatient CR/SP programs, significant changes have occurred. This statement updates the responsibilities of CR/SP medical directors, in view of changes in federal legislation and regulations and changes in health care delivery and clinical practice that impact the roles and responsibilities of CR/SP medical directors.
