Importance of individualizing treatment decisions in girls with central precocious puberty when initiating treatment after age 7 years or continuing beyond a chronological age of 10 years or a bone age of 12 years.

OBJECTIVES: Gonadotropin-releasing hormone agonist treatment is important for optimal growth in girls with central precocious puberty (CPP). Data are lacking regarding benefit to height outcome when treatment is started after chronological age (CA) of 7 years, and if continued beyond CA of 10 years or bone age (BA) of 12 years. METHODS: Forty-eight girls with CPP were treated with monthly leuprolide depot. Change in predicted adult height (PAH) during treatment was assessed. Changes in PAH and growth velocity were compared between girls initiating treatment at CA <7 vs. ≥7 years, and BA ≥12 vs. BA <12 years. RESULTS: Mean baseline CA was 6.8 years, BA, 10.2 years; and PAH, 156.4 cm. BA/CA ratio decreased from pretreatment values, averaging 1.5 to 1.2 at the end of treatment. Proportion of girls with >5 cm PAH change during treatment was similar, and PAH increased throughout treatment in most girls, regardless of age at treatment initiation. PAH continued to increase in 16/19 girls who continued treatment after BA of 12 years, and also in 16/22 girls who continued treatment after CA of 10 years. CONCLUSIONS: PAH improved in most girls who initiated treatment after CA of 7 years. It continued to improve in most girls with longer treatment, even past BA of 12 years or CA of 10 years, which suggests that no absolute CA or BA limit should define initiation or end of treatment. Treatment plans need to be individualized, and neither treatment initiation nor cessation should be based on BA or CA alone.

Comparison of Weight-Based Dosing versus Fixed Dosing of 23.4% Hypertonic Saline for Intracranial Pressure Reduction in Patients with Severe Traumatic Brain Injury.

CONTEXT: Hypertonic saline (HTS) is a pharmacologic therapy used in patients with severe traumatic brain injuries to decrease intracranial pressure (ICP) associated with cerebral edema. AIMS: The purpose of this study was to compare ICP reduction between fixed doses of 23.4% HTS and weight-based doses. SETTING AND DESIGN: This was a retrospective study that included adult patients at a level 1 trauma center who had nonpenetrating traumatic brain injury, an ICP monitor, and received at least one dose of 23.4% HTS. SUBJECTS AND METHODS: Doses were classified as either high weight-based (>0.6 ml/kg), low weight-based (<0.6 ml/kg), or standard fixed dose (30 ml). Only doses given within 5 days post-injury were evaluated. Percent reduction in ICP was compared pre- and post-dose between dosing groups, and each dose was evaluated as a separate episode. STATISTICAL ANALYSIS: The primary and secondary endpoints for the study were analyzed using mixed-model, repeated-measures analysis of covariance. RESULTS: A total of 97 doses of HTS were evaluated. The primary endpoint of ICP reduction showed a 42.5% decrease in ICP after the administration of a high weight-based dose, a 36.7% reduction after a low weight-based dose, and a 31.5% reduction after a fixed dose. There was no significant relationship between dose group and percent change in ICP (P = 0.25). A sub-analysis of doses received within 48 h postinjury found a significant relationship between both dose group and percent change in ICP, and initial ICP and percent change in ICP (P = 0.04, and <0.0001 respectively). CONCLUSIONS: Our data did not show a significant difference between fixed- and weight-based doses of 23.4% HTS for ICP reduction.

Predictors of No-show Rate in the GI Endoscopy Suite at a Safety Net Academic Medical Center.

BACKGROUND/OBJECTIVES: Noncompliance with physician and procedure appointments is associated with poor disease control and worse disease outcomes. This also impacts the quality of care, decreases efficiency, and affects revenue. Studies have shown that no-show rates are higher in clinics caring for underserved populations and may contribute to poorer health outcomes in this group. METHODS: We performed a 17-month retrospective observational cohort study of patients scheduled for outpatient procedures in the Gastroenterology endoscopy suite at the University of Florida Health, Jacksonville. Multivariate logistic regression analysis was performed to evaluate associations between attendance and predictors of no-show. RESULTS: In total, 6157 patients were scheduled to undergo different GI procedures during the study period. A total of 4388 (71%) patients completed their procedure, whereas 2349 (29%) failed to attend their appointment and were considered "no-show". There was a significant relationship between the visit attendance and race, insurance, gender, and marital status. Males had a higher no-show rate compared with females (30% vs. 28%; P<0.05). African Americans had the highest no-show rate (32%; P<0.05) amongst different races. Patients scheduled for surveillance colonoscopy (ie, history of polyps, IBD, Colon cancer) were more likely to show (78%) than those obtaining initial colorectal cancer screening (74%) or other indications (71%) (P<0.05).In the logistic regression model, patients with commercial insurance are more likely to show for their appointments than those with noncommercial insurance (eg, Medicare, Medicaid, City contract etc) [odds ratio (OR), 2.6; 95% confidence interval (CI), 2.2-3.0]. The odds of showing up are 1.7 times higher for married men compared with single men (OR, 1.7; 95% CI, 1.3-2.0). Similarly, married females are more likely to show up for appointment than single females (OR, 1.1; 95% CI, 0.9-1.3). We did not find significant association between the type of GI procedure (eg, colonoscopy vs. esophagogastroduodenoscopy vs. advanced endoscopic procedures) (P>0.05). CONCLUSIONS: Predictors of no-shows for endoscopic gastrointestinal procedures included unpartnered or single patients, African American race and noncommercial insurance providers. Patients scheduled for surveillance colonoscopy had better adherence than initial screening. Further studies are required to better characterize these factors and improve adherence to the outpatient appointments based on the identified predictors.

Effects of Immunomodulators and Biologic Agents on Sexual Health in Patients With Inflammatory Bowel Disease.

BACKGROUND: Although much knowledge has been gained regarding the medical and surgical management of inflammatory bowel disease (IBD), a paucity of information is available on the psychosexual issues related to IBD. The aim of this study was to evaluate the sexual health of patients with IBD who were taking immunomodulators and/or biologic agents vs patients with IBD who were not on that medication regimen. METHODS: All study participants completed a validated sexual health questionnaire, the Female Sexual Function Index or the International Index of Erectile Function, to assess their subjective perception of the effect of IBD on the different domains of sexual function during the prior 1-month time period. RESULTS: No statistically significant differences in any baseline demographic variables were found for either sex between the group taking immunomodulators/biologic agents and the nontreatment group. Among females and males, individual question responses, domain scores, and total scores showed no statistically significant differences between the 2 treatment groups. CONCLUSION: Our data suggest that the use of immunomodulators or biologic agents does not affect female or male sexual health. However, treatment of patients with IBD must be individualized based on the aggressive nature of the disease, treatment goals, and the tolerability of various medications.

Evaluating the effects of diffused lavender in an adult day care center for patients with dementia in an effort to decrease behavioral issues: a pilot study.

Objectives: To evaluate the effects of diffused lavender on the frequency of behavioral issues [BIs], defined as a composite of restlessness/wandering [RW], agitation [AGT], anger [ANG], and anxiety [ANX] in an adult day care center. Secondary objectives evaluate systematic differences on the frequency of BIs between age cohorts, gender, and individual behaviors. Design: Pre-post quasi-experimental study. Setting: Private nonprofit adult day care center for patients with dementia. Participants: Elderly patients older than 65 years of age with a clinical diagnosis of dementia, who require daytime monitoring. Intervention: Lavender aromatherapy twice a day for 20 min during a two-month period during active clinic days. Measurements: Behavioral issues were recorded using the behavior/intervention monthly flow record during the pre- and post-intervention periods. Results: There was no significant difference on frequency of BIs between pre-intervention and post-intervention periods (p = .06). There was a significant difference between pre-intervention and post-intervention total number of AGT occurrences (129 vs. 25; p value < .01). There was no significant difference between age cohorts for computed difference of RW, ANG, and ANX issues. There was a significant difference between age cohorts for computed difference of AGT (p value = .04) as the 70-85 age cohort showed less agitation compared to the 85-100 age cohort. Conclusion: The use of diffused lavender twice daily has shown to reduce the frequency of agitation in elderly patients with dementia, especially in the 70-85 age cohort. Though diffused lavender did not show statistical differences in the frequency of other behaviors (restlessness/wander, anger, anxiety), the study population may have been too small to find a difference.

Clinical utility of methicillin-resistant Staphylococcus aureus nasal polymerase chain reaction assay in critically ill patients with nosocomial pneumonia.

PURPOSE: This study investigated the diagnostic performance characteristics of a methicillin-resistant Staphylococcus aureus (MRSA) nasal polymerase chain reaction (PCR) assay in critically ill patients with nosocomial pneumonia. MATERIALS AND METHODS: This retrospective, single-center study included adult patients admitted to an intensive care unit with suspected nosocomial pneumonia. Patients must have received an MRSA nasal PCR assay and respiratory culture within predetermined time intervals. The primary outcome included the diagnostic performance characteristics of the assay. Secondary outcomes included the change in negative predictive value (NPV) over time, rate of acute kidney injury, and cost avoidance associated with vancomycin and monitoring. RESULTS: In 400 patients meeting inclusion criteria, the prevalence of culture confirmed MRSA pneumonia was 9.3%. When compared to initial cultures, the PCR assay demonstrated 91.89% sensitivity and 84.3% specificity with a positive predictive value and NPV of 37.36% and 99.03%. The NPV decreased to 87.5% at 21.9 days. No difference was found in rates of acute kidney injury. A cost avoidance of $108 per patient was estimated in patients de-escalated based on negative results. CONCLUSION: In critically ill patients, an MRSA nasal PCR assay has a high NPV for nosocomial pneumonia and can be used to guide vancomycin de-escalation.

Ultrasound-Guided Peripheral Intravenous Catheter Training Results in Physician-Level Success for Emergency Department Technicians.

OBJECTIVES: To report our success and complication rates with emergency department (ED) technician-performed ultrasound (US)-guided peripheral intravenous (IV) catheter placement and to compare our results to similar studies in the literature. METHODS: We conducted a retrospective review of a prospective database of patients who underwent US-guided peripheral IV catheter placement attempts for clinical care in the ED. All patients meeting difficult IV access criteria who had a US-guided peripheral IV catheter placement attempted by a trained ED technician were included. Average attempts per success and overall success rates were compared to similar published studies. RESULTS: There were 830 participants, with an overall success rate of ED technician- performed US-guided peripheral IV catheter placement of 97.5%. Clinicians categorized 82.6% of participants as having difficult IV access and reported that in 46.5%, a central venous catheter would have been necessary if the US-guided peripheral IV catheter failed. Of successful catheter attempts, 86.8% were placed on the first attempt; 11.6% were placed on the second attempt; and 1.6% were placed on the third attempt. For this study, the average number of attempts per success was 1.15 (95% confidence interval, 1.12-1.18), which was lower than in 6 other published studies, ranging from 1.27 to 1.70. The overall success rate of our ED technician-performed attempts was 0.970 (95% confidence interval, 0.956-0.983), which was higher than that reported in previous ED technician studies (0.79-0.80), and closer to that reported for physicians or nurses (0.87-0.97). The arterial puncture complication rate was 0.8%, which was also lower than in other published studies (1.25%-9.80%). CONCLUSIONS: With brief but comprehensive training, ED technicians can successfully obtain US-guided peripheral IV catheter access in patients with difficult IV access.

Opening a New Level II Trauma Center Near an Established Level I Trauma Center: Is This Good for Trauma Care?

OBJECTIVES: To describe how the initiation and later removal of a provisional level II trauma center (PL2TC) status at a community hospital affected the volume and severity of injured patients seen at an established academic level 1 trauma center (AL1TC). METHODS: Census data including counts of injury ICD-9 codes and patients seen in the emergency department (ED) and trauma center at an AL1TC were collected monthly from January 2010 to October 2014. An interrupted time series analysis was used to model the monthly census data with 2 time interruptions to describe the change in patient volume at the interruptions. The interruptions were (1) the initiation of the PL2TC status at a nearby community hospital and (2) the subsequent removal of the PL2TC status. RESULTS: The number of diagnoses, encounters, and patients seen at the AL1TC ED decreased while the PL2TC was operating. After the removal of the PL2TC status, there was a 19.4% increase in the ED patient volume per month at the AL1TC. The number of orthopaedic trauma patients seen through the ED at the AL1TC dropped 11.1% per month when the PL2TC began functioning as a trauma center. However, the volume of orthopaedic patients at the AL1TC did not recuperate after the PL2TC lost level 2 status. CONCLUSIONS: A significant decrease in patient volume was seen at the AL1TC with the initiation of the PL2TC in close proximity. Orthopaedic patient volume did not recuperate after the removal of the PL2TC status.

Impact of an antimicrobial stewardship initiative to evaluate ß-lactam allergy in patients ordered aztreonam.

PURPOSE: An evaluation of the clinical and economic impact of an antimicrobial stewardship quality initiative (ASQI) focusing on allergy assessment in patients with a documented ß-lactam allergy prescribed aztreonam was conducted. METHODS: This retrospective study was executed at a hospital with an interdisciplinary antimicrobial stewardship program (ASP). A total of 186 patients with self-reported ß-lactam allergies who were prescribed aztreonam while admitted during a 36-month time period surrounding the ASQI implementation were included. The primary study outcome was median time in hours to aztreonam discontinuation among nonanaphylactic patients. RESULTS: After implementation of the ASQI, the percentage of patients continued on aztreonam for the duration of therapy was nearly cut in half, and a greater percentage of patients were switched to ß-lactam antibiotics. No adverse effects associated with ß-lactam therapy were observed in any study patient. Antimicrobial cost savings was not associated with any difference in clinical outcomes. Overall, hospitalwide aztreonam prescribing and aztreonam use declined. Institutional aztreonam orders per 1000 patient-days decreased from 1.5 to 1 after implementation of the ASQI. Additionally, hospitalwide aztreonam days of therapy per 1000 patient-days was reduced from 3.6 in the pre-ASQI period to 1.8 in the post-ASQI period. CONCLUSION: An ASQI that included critical evaluation of patient-reported ß-lactam allergies led to decreased aztreonam use, reduced antimicrobial expenditure, and similar clinical outcomes to those observed before implementation.

An Elephant in the Emergency Department: Symptom of Disparities in Cancer Care.

Reliance on emergency departments (EDs) by economically disadvantaged people for initial cancer diagnosis in place of primary care and early diagnosis and treatment is 1 obvious plausible explanation for cancer disparities. Claims data from a safety net hospital for the years 2009-2010 were merged with hospital tumor registry data to compare hospitalizations for ED-associated initial cancer diagnoses to non-ED associated initial diagnoses. The proportion of initial cancer diagnoses associated with hospital admissions through the ED was relatively high (32%) for all safety net hospital patients, but disproportionately higher for African Americans and residents of the impoverished urban core. Use of the ED for initial diagnosis was associated with a 75% higher risk of stage 4 versus stage 1 cancer diagnosis, and a 176% higher risk of dying during the 2-year study period. Findings from this study of ED use within a safety net hospital documented profound disparities in cancer care and outcomes with major implications for monitoring disparities, Affordable Care Act impact, and safety net hospital utilization.

Poisonings with Suicidal Intent Aged 0-21 Years Reported to Poison Centers 2003-12.

INTRODUCTION: Few studies explore the clinical features of youth suicide by poisoning. The use of both social and clinical features of self-poisoning with suicidal intent could be helpful in enhancing existing and creating new prevention strategies. We sought to characterize self-poisonings with suicide intent in ages 0 to 21 years reported to three regional poison control centers from 2003-2012. METHODS: This study was a blinded retrospective review of intentional self-poisonings by those age 21 or younger captured by the Poison Information Control Network. Age, sex, substance(s) used, medical outcome, management site, clinical effects, and therapies were described using counts and percentages and analyzed using chi-square tests. We analyzed the medical outcome ranging from no effect to death using the Wilcoxon rank-sum test. Serious medical outcome was defined as death or major outcome. RESULTS: We analyzed a total of 29,737 cases. The majority were females (20,945;70.5%), of whom 274 (1.3%) were pregnant. Most cases were 15-18 year olds (15,520;52.2%). Many experienced no effects (9,068;30.5%) or minor medical outcomes (8,612;29%). Males had more serious medical outcomes (p<0.0001), but females were more likely to be admitted to a critical care unit (p<0.0001). There were 17 deaths (0.06%), most in males (10;p=0.008). Of the 52 substances reported in the death cases, 12 (23.1%) were analgesics. In eight (47.1%) of the deaths, over two substances were used. Overall, drowsiness/lethargy (7,097;19.3%) and single-dose charcoal (8,815;16.3%) were frequently reported. Nearly 20% were admitted to critical care units (5,727;19.3%) and 28.7% went to psychiatric facilities (8,523). Of those admitted to hospitals (8,203), nearly 70% (5,727) required critical care units. Almost half <10 years old were evaluated and released (43;47.2%). Of the 114 reported substances for this population, 22.8% involved psychotropic medications, 15.8% analgesics, and 14% Attention Deficit-Hyperactive Disorder (ADHD) medications. Analgesics (13,539;33.6%) were the most common medication category used by all age groups. Typically only one substance (20,549;69.1%) was used. CONCLUSION: Undiagnosed ADHD may be a potential underlying cause for self-harming behaviors in the very young. Gender-specific suicide prevention strategies may be more effective at identifying those at risk than traditional measures alone. Further study into admitting practices by emergency physicians is needed to understand the difference in critical care admission rates based on gender. Once identified to be at-risk for suicidal behavior, access to analgesics and psychotropics should be monitored by care-givers especially in those between the ages of 15-18.

A Stewardship Approach To Optimize Antimicrobial Therapy through Use of a Rapid Microarray Assay on Blood Cultures Positive for Gram-Negative Bacteria.

A Gram-negative (GN) blood culture microarray assay with an antimicrobial stewardship program (ASP) intervention was evaluated in 126 patients with GN bacteremia. The median time to optimal therapy was shorter in the postintervention group than in the preintervention group (49.3 h versus 38.5 h, respectively; P = 0.0199). ASP can utilize microarray technology to decrease the time to optimal antimicrobial therapy.
