The uptake of family screening in hypertrophic cardiomyopathy and an online video intervention to facilitate family communication.

BACKGROUND: Individuals with hypertrophic cardiomyopathy (HCM), even when asymptomatic, are at-risk for sudden cardiac death and stroke from arrhythmias, making it imperative to identify individuals affected by this familial disorder. Consensus guidelines recommend that first-degree relatives (FDRs) of a person with HCM undergo serial cardiovascular evaluations. METHODS: We determined the uptake of family screening in patients with HCM and developed an online video intervention to facilitate family communication and screening. Family screening and genetic testing data were collected through a prospective quality improvement initiative, a standardized clinical assessment and management plan (SCAMP), utilized in an established cardiovascular genetics clinic. Patients were prescribed an online video if screening of their FDRs was incomplete and a pilot study on video utilization and family communication was conducted. RESULTS: Two-hundred and sixteen probands with HCM were enrolled in SCAMP Phase I and 190 were enrolled in SCAMP Phase II. In both phases, probands reported that 51% of FDRs had been screened (382/749 in Phase I, 258/504 in Phase II). Twenty patients participated in a pilot study on video utilization and family communication. Nine participants reported watching the video and six participants reported sharing the video with relatives; however only one participant reported sharing the video with relatives who were not yet aware of the diagnosis of HCM in the family. CONCLUSION: Despite care in a specialized cardiovascular genetics clinic, approximately one half of FDRs of patients with HCM remained unscreened. Online interventions and videos may serve as supplemental tools for patients communicating genetic risk information to relatives.

A Decision-Making Algorithm for Initiation and Discontinuation of RRT in Severe AKI.

BACKGROUND AND OBJECTIVES: AKI is an increasingly common and devastating complication in hospitalized patients. Severe AKI requiring RRT is associated with in-hospital mortality rates exceeding 40%. Clinical decision making related to RRT initiation for patients with AKI in the medical intensive care unit is not standardized. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a 13-month (November of 2013 to December of 2014) prospective cohort study in an academic medical intensive care unit involving the implementation of an AKI Standardized Clinical Assessment and Management Plan, a decision-making algorithm to assist front-line clinicians caring for patients with AKI. The Standardized Clinical Assessment and Management Plan algorithms provided recommendations about optimal indications for initiating and discontinuing RRT on the basis of various clinical parameters; 176 patients managed by nine nephrologists were included in the study. We captured reasons for deviation from the recommended algorithm as well as mortality data. RESULTS: Patients whose clinicians adhered to the Standardized Clinical Assessment and Management Plan recommendation to start RRT had lower in-hospital mortality (42% versus 63%; P<0.01) and 60-day mortality (46% and 68%; P<0.01), findings that were confirmed after multivariable adjustment for age, albumin, and disease severity. There was a differential effect of Standardized Clinical Assessment and Management Plan adherence in low (<50% mortality risk) versus high (≥50% mortality risk) disease severity on in-hospital mortality (interaction term P=0.02). In patients with low disease severity, Standardized Clinical Assessment and Management Plan adherence was associated with lower in-hospital mortality (odds ratio, 0.21; 95% confidence interval, 0.08 to 0.54; P=0.001), but no significant association was evident in patients with high disease severity. CONCLUSIONS: Physician adherence to an algorithm providing recommendations on RRT initiation was associated with lower in-hospital mortality.

Implementation of a Risk Stratification and Management Pathway for Acute Chest Pain in the Emergency Department.

OBJECTIVES: Chest pain is a common complaint in the emergency department, and a small but important minority represents an acute coronary syndrome (ACS). Variation in diagnostic workup, risk stratification, and management may result in underuse, misuse, and/or overuse of resources. METHODS: From July to October 2014, we conducted a prospective cohort study in an academic medical center by implementing a Standardized Clinical Assessment and Management Plan (SCAMP) for chest pain based on the HEART score. In addition to capturing adherence to the SCAMP algorithm and reasons for any deviations, we measured troponin sample timing; rates of stress test utilization; length of stay (LOS); and 30-day rates of revascularization, ACS, and death. RESULTS: We identified 239 patients during the enrollment period who were eligible to enter the SCAMP, of whom 97 patients were entered into the pathway. Patients were risk stratified into one of 3 risk tiers: high (n = 3), intermediate (n = 40), and low (n = 54). Among low-risk patients, recommendations for troponin testing were not followed in 56%, and 11% received stress tests contrary to the SCAMP recommendation. None of the low-risk patients had elevated troponin measurements, and none had an abnormal stress test. Mean LOS in low-risk patients managed with discordant plans was 22:26 h/min, compared with 9:13 h/min in concordant patients (P < 0.001). Mean LOS in intermediate-risk patients with stress testing was 25:53 h/min, compared with 7:55 h/min for those without (P < 0.001). At 30 days, 10% of intermediate-risk patients and 0% of low-risk patients experienced an ACS event (risk difference 10% [0.7%-19%]); none experienced revascularization or death. The most frequently cited reason for deviation from the SCAMP was lack of confidence in the tool. CONCLUSIONS: Compliance with SCAMP recommendations for low- and intermediate-risk patients was poor, largely due to lack of confidence in the tool. However, in our study population, outcomes suggest that deviation from the SCAMP yielded no additional clinical benefit while significantly prolonging emergency department LOS.

Urinalysis in acute care of adults: pitfalls in testing and interpreting results.

BACKGROUND: Rapid urine tests for infection (urinalysis, dipstick) have low up-front costs. However, many false positives occur, with important downstream consequences, including unnecessary antibiotics. We studied indications, collection technique, and results of urinalyses in acute care. METHODS: This research was a prospective observational study of a convenience sample of emergency department (ED) patients who had urinalysis performed between June 1, 2012 and February 15, 2013 at an urban teaching hospital. Analyses were conducted via t tests, χ(2) tests, and multivariable logistic regression. RESULTS: Of 195 cases included in the study, the median age was 56 and 70% of participants were female. There were specific symptoms or signs of urinary tract infection (UTI) in 74 cases (38%; 95% confidence interval [CI], 31%-45%), nonspecific symptoms or signs in 83 cases (43%; 95% CI, 36%-50%), and no symptoms or signs of UTI in 38 cases (19%; 95% CI, 14%-25%). The median age was 51 (specific symptoms), 58 (nonspecific symptoms), and 61 (no symptoms), respectively (P = .005). Of 137 patients who produced the specimen without assistance, 78 (57%; 95% CI, 48%-65%) received no instructions on urine collection. Correct midstream clean-catch technique was used in 8 of 137 cases (6%). Presence of symptoms or signs was not associated with a new antibiotic prescription, but positive urinalysis (OR, 4.9; 95% CI, 1.7-14) and positive urine culture (OR, 3.6; 95% CI, 1.1-12) were. Of 36 patients receiving antibiotics, 10 (28%; 95% CI, 13%-43%) had no symptoms or nonspecific symptoms. CONCLUSION: In this sample at an urban teaching hospital ED, urine testing was not driven by symptoms. Improving practice may lower costs, improve efficiency of care, decrease unnecessary data that can distract providers and impair patient safety, decrease misdiagnosis, and decrease unnecessary antibiotics.

Clinical trial: comparative effectiveness of cephalexin plus trimethoprim-sulfamethoxazole versus cephalexin alone for treatment of uncomplicated cellulitis: a randomized controlled trial.

BACKGROUND: Community-associated methicillin-resistant S. aureus (CA-MRSA) is the most common organism isolated from purulent skin infections. Antibiotics are usually not beneficial for skin abscess, and national guidelines do not recommend CA-MRSA coverage for cellulitis, except purulent cellulitis, which is uncommon. Despite this, antibiotics targeting CA-MRSA are prescribed commonly and increasingly for skin infections, perhaps due, in part, to lack of experimental evidence among cellulitis patients. We test the hypothesis that antibiotics targeting CA-MRSA are beneficial in the treatment of cellulitis. METHODS: We performed a randomized, multicenter, double-blind, placebo-controlled trial from 2007 to 2011. We enrolled patients with cellulitis, no abscesses, symptoms for <1 week, and no diabetes, immunosuppression, peripheral vascular disease, or hospitalization (clinicaltrials.gov NCT00676130). All participants received cephalexin. Additionally, each was randomized to trimethoprim-sulfamethoxazole or placebo. We provided 14 days of antibiotics and instructed participants to continue therapy for ≥1 week, then stop 3 days after they felt the infection to be cured. Our main outcome measure was the risk difference for treatment success, determined in person at 2 weeks, with telephone and medical record confirmation at 1 month. RESULTS: We enrolled 153 participants, and 146 had outcome data for intent-to-treat analysis. Median age was 29, range 3-74. Of intervention participants, 62/73 (85%) were cured versus 60/73 controls (82%), a risk difference of 2.7% (95% confidence interval, -9.3% to 15%; P = .66). No covariates predicted treatment response, including nasal MRSA colonization and purulence at enrollment. CONCLUSIONS: Among patients diagnosed with cellulitis without abscess, the addition of trimethoprim-sulfamethoxazole to cephalexin did not improve outcomes overall or by subgroup. CLINICAL TRIALS REGISTRATION: NCT00676130.

The time burden of alcohol-based hand cleanser when using nonsterile gloves.

We quantified the time burden of alcohol-based handrub accompanying nonsterile-glove use among emergency physicians, through observation in controlled and clinical settings. We report gloving episodes per hour, gloving times with and without handrub, and handrub recommendations compliance. Handrub adds 46 seconds to each glove-use episode, and we provide national extrapolations.

Experience with Kangaroo mother care in a neonatal intensive care unit (NICU) in Chandigarh, India.

OBJECTIVE: To study the feasibility and acceptability of Kangaroo mother care (KMC) on the low birth weight infants (LBWI) in the neonatal intensive care unit (NICU) by the mothers, family members and health care workers (HCW) and to observe its effect on the vital parameters of the babies. METHOD: A observation in the NICU. RESULTS: A total of 135 babies (74 boys and 61 girls) who completed minimum of 4 hrs of KMC/day, were included. The mean birth weight and gestation were 1460 gm and 30 week respectively. 47% babies started KMC within first week of age. Mean duration of KMC was 7 days (3-48) days. The O(2) saturation improved by 2-3%, temperature ( degrees C) rose from 36.75 +/- 0.19 to 37.23 +/- 0.25, respiration stabilized (p<0.05 for all) and heart rate dropped by 3-5 beats. No episodes of hypothermia or apnea were observed during KMC. KMC was accepted by 96 % mothers, 82% fathers and 84% other family members. 94% HCW considered it to be safe and conservative method of care of LBWI. Benefits of KMC on the babies' behavior and on maternal confidence and lactation were reported by 57%, 94% and 80% respectively. A decline in use of heating devices in the NICU was reported by 85% and 79% said it did not increase their work load. CONCLUSION: KMC was found to be safe, effective and feasible method of care of LBWI even in the NICU settings. Positive attitudes were observed in mothers, families and HCW.
