Management and Outcomes of Salmonella Gastroenteritis in the Era of Rapid Molecular Testing.

BACKGROUND AND OBJECTIVES: Molecular diagnostics provide a rapid and sensitive diagnosis of gastroenteritis compared with a stool culture. In this study, we seek to describe the changes in medical management and outcomes of children with Salmonella gastroenteritis as our hospital system adopted molecular diagnostics. METHODS: This study is a retrospective chart review of children <18 years of age diagnosed with nontyphoidal Salmonella gastroenteritis between 2008 and 2018 at a large pediatric health care system in the southeastern United States. Those with immunocompromising conditions and hemoglobinopathies were excluded. Patients diagnosed via molecular testing were compared with those diagnosed solely by stool culture for aspects of management including admission rates, blood culture obtainment, and antibiotic administration. RESULTS: Of 965 eligible patients with Salmonella gastroenteritis, 264 (27%) had a stool molecular test and 701 (73%) only had a stool culture performed. Groups were similar in age and presentation. Those diagnosed by molecular methods had higher hospitalization rates (69% vs 50%, P <.001), more blood cultures obtained (54% vs 44%, P <.01), and received more antibiotics (49% vs 34%, P <.001) despite statistically similar rates of bacteremia (11% vs 19%, P = .05). CONCLUSIONS: The rapid diagnosis of Salmonella gastroenteritis by molecular methods was associated with increased hospital admission rates, blood culture obtainment, and antibiotic use. This suggests possible overmedicalization of uncomplicated Salmonella gastroenteritis, and clinicians should remain cognizant of the possibility of providing low-value care for uncomplicated disease.

Intravenous Antibiotic Duration for Nontyphoidal Salmonella Bacteremia in Children.

BACKGROUND AND OBJECTIVE: The optimal duration of intravenous (IV) antibiotic therapy for children with nontyphoidal Salmonella bacteremia (NTSB) is unknown. The objective of the authors of this study is to evaluate differences in outcomes among children with NTSB who received a short (≤3 days; short-duration group [SDG]) versus long (>3 days; long-duration group [LDG]) course of IV antibiotics. METHODS: This is a retrospective study of children 3 months to 18 years old with NTSB admitted to a tertiary pediatric health care system in the southeastern United States between 2008 and 2018. RESULTS: Among 57 patients with NTSB without focal infection, 24 (42%) were in the SDG and received IV antibiotics for a median of 3.0 days and 33 (58%) were in the LDG and received IV antibiotics for a median of 5.0 days. Demographic and clinical characteristics were similar between the SDG and LDG. The median total duration of antibiotics was 11.5 days in the SDG and 13.0 in the LDG (P = .068). The median length of stay was 3.0 days in the SDG and 4.0 in the LDG (P ≤ .001). Two children in the SDG (8%) and 1 child in the LDG (3%) returned to the emergency department for care unrelated to the duration of their IV antibiotic therapy (P = .567). None of the children were readmitted for sequelae related to salmonellosis. CONCLUSIONS: The duration of IV antibiotics varied for NTSB, but the outcomes were excellent regardless of the initial IV antibiotic duration. Earlier transitions to oral antibiotics can be considered for NTSB.

Incorporating the Voice of Community Based Pediatricians to Improve Discharge Communication.

INTRODUCTION: Communication between pediatric hospitalists and primary care physicians (PCPs) at discharge is an essential part of a successful transition to home. While many hospitals require communicating with PCPs for all admitted patients, it is unknown if PCPs find such communication valuable or if it improves outcomes. Our global aim was to improve discharge communication for patients that pediatric hospitalists and PCPs deemed appropriate. METHODS: We sent surveys to 422 outpatient pediatricians in our care network to understand their communication preferences. Survey results informed local guidelines for when hospitalists should directly contact PCPs. We determined the proportion of inpatient discharges meeting those guidelines and set a target for our primary process metric: the proportion of discharges with attempted direct PCP contact. We engaged in Plan-Do-Study-Act cycles, including a discharge documentation tool in the electronic health record, education of inpatient teams, email reminders including group performance data, asynchronous Health Insurance Portability and Accountability Act-compliant messaging application, and competitions that shared blinded individual data. RESULTS: We increased the percentage of documented direct communication with the PCPs from 2% to 33% and from 4% to 65% for those who met guidelines for direct communication. CONCLUSIONS: PCPs only want direct communication on a subset of discharges. Interventions focused on high-yield populations improved discharge communication in our institution.

Pediatric Residency Obesity and Overweight Training Curricula: A Systematic Review.

Background. Pediatric obesity has become a significant public health concern. Pediatricians are the ideal group to help identify and treat this epidemic, but unfortunately, many pediatricians are not trained to discuss obesity with patients and their families. Standardized training initiatives for pediatric residents on prevention and/or management of obesity are needed to equip emerging pediatricians to combat the obesity epidemic. Objectives. This systematic literature review aims to examine the effectiveness of childhood obesity prevention/counseling resident training interventions. Methods. A comprehensive literature search was performed using preidentified search terms and limited to articles published prior to November 6, 2019. Articles were analyzed by 2 reviewers with a standardized evaluation tool. Results. A total of 698 articles were identified by the search. These were reduced to 111 articles after title review and 11 articles following abstract/full paper review. The 11 articles described 10 different obesity training interventions for residents. The articles varied in their size, length of training session, and study design. Despite these variations, all articles outlined positive outcomes, including an increase in physician confidence, positive changes in behavior, and/or improved electronic medical record documentation. Conclusions. With the continued increase in pediatric obesity, there is a need for practical, easy-to-implement, standardized trainings for pediatric residents on obesity prevention and treatment. More investigation needs to be done to look at long-term results of current interventions as well as other outcomes such as whether physicians are correctly identifying patients who are overweight or obese and whether there is improvement in patient follow-up.

Declining Prevalence of Methicillin-Resistant Staphylococcus aureus Septic Arthritis and Osteomyelitis in Children: Implications for Treatment.

This study sought to assess clinical characteristics and differences in outcomes between children with Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA) osteomyelitis or septic arthritis and whether initial antibiotic regimen affects patient outcomes. We analyzed records of children ages 15 days to 18 years admitted between 2009 and 2016 to two tertiary children's hospitals who were diagnosed with an osteoarticular infection and had a microorganism identified. A total of 584 patients met inclusion criteria, of which 365 (62.5%) had a microbiological diagnosis. MSSA was the most common pathogen identified (45.5%), followed by MRSA (31.2%). Compared to MSSA, patients with MRSA had a higher initial C-reactive protein and longer hospitalization. Patients whose initial antibiotic regimens included vancomycin had a longer hospitalization than those initiated on clindamycin without vancomycin, even after removing sicker patients admitted to the pediatric intensive care unit. While MRSA was associated with increased severity of osteoarticular infections compared to MSSA, the incidence of MRSA has been declining at our institution. Patients with longer lengths of stay were more likely to be on vancomycin. Clindamycin should be considered in the initial antibiotic regimen for osteomyelitis and septic arthritis with ongoing surveillance of local microbiology and outcomes.

Effect of Child Overweight/Obesity Didactic Session on Resident Confidence and Detection.

Objective. To evaluate the impact of an obesity didactic session for pediatric physicians on confidence in counseling and identified overweight/obesity and follow-up recommendations. Methods. Pediatric residents underwent training and completed pre/post online surveys evaluating confidence in obesity prevention and identification. A booster training occurred 1 year later. Pre-/post-training scores were compared using χ2 or Fisher's exact tests. Electronic medical records data for patients ≥3 years with BMI-for-age percentile ≥85 during 3 months prior/following the training/booster compared frequency of overweight/obesity identification and follow-up recommendations (≤3 months recommended vs longer) using logistic regression adjusting for age and overweight/obese status. Results. Post trainings, improvements in confidence to define/screen for obesity were observed, with a decline between trainings. Overweight/obese identification and follow-up time recommendations improved post-training (identification: 14.2% to 27.4%, adjusted odds ratio [aOR] = 3.16, 95% confidence interval [CI] = 1.54-6.51; follow-up: 48.9% to 58.9%, aOR = 1.63, 95% CI = 1.01-2.64), aOR = 1.77, 95% CI = 1.10-2.85, and identification remained stable/above pre-training rates both pre-/post-booster (25.8%, aOR = 3.14, 95% CI = 1.53-6.45; and 22.1%, aOR = 2.57, 95% CI = 1.25-5.30, respectively). Recommended follow-up time rates continued to rise when measured pre-booster (60.6%, aOR = 1.77, 95% CI = 1.10-2.85), then declined (46.0%, aOR = 0.95, 95% CI = 0.60-1.52). Conclusion. This didactic session improved resident confidence in defining/screening, identification of overweight/obesity and follow-up recommendations; however, rates of identification remained low. The successes of this intervention support similar didactic sessions in residency programs and identifies opportunities for improved resident/attending education.

Substance abuse treatment patients with early onset cocaine use respond as well to contingency management interventions as those with later onset cocaine use.

Early onset drug use is associated with increased risk of developing substance use disorders, but relatively little is known about the correlates of early drug use among adults receiving treatment. A retrospective analysis of a randomized study of contingency management treatment compared cocaine-dependent patients who reported initial cocaine use at age 14 or younger (n = 41) to those who began using after age 14 (n = 387). Patients with early onset cocaine use had more legal and psychiatric problems than those who initiated cocaine use later. Patients with early-onset cocaine use also dropped out of treatment sooner and achieved less sustained abstinence than those who began using at older ages, but the interaction between age of first use and treatment condition was not significant. Early-onset cocaine use is associated with persistent psychosocial problems and an overall poor response to treatment. However, contingency management is efficacious in improving outcomes in early onset cocaine users.

Older methadone patients achieve greater durations of cocaine abstinence with contingency management than younger patients.

BACKGROUND AND OBJECTIVES: Contingency management (CM) interventions are efficacious in treating cocaine abusing methadone patients, but few studies have examined the effect of age on treatment outcomes in this population. This study evaluated the impact of age on treatment outcomes in cocaine abusing methadone patients. METHODS: Data were analyzed from 189 patients enrolled in one of three randomized studies that evaluated the efficacy of CM versus standard care (SC) treatment. RESULTS: Age was associated with some demographics and drug use characteristics including racial composition, education, and methadone dose. Primary drug abuse treatment outcomes did not vary across age groups, but CM had a greater benefit for engendering longer durations of abstinence in the middle/older and older age groups compared to the younger age groups. At the 6-month follow-up, submission of a cocaine positive urine sample was predicted by submission of a cocaine positive sample at intake, higher methadone doses, and assignment to SC rather than CM treatment. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: As substance abusers are living longer, examination of the efficacy of pharmacological and psychosocial treatments specifically within older age groups may lead to a better understanding of subpopulations for whom enhanced treatments such as CM are warranted.

Interaction effects of age and contingency management treatments in cocaine-dependent outpatients.

As the American population ages, older adults are accounting for a larger percentage of the drug-abusing population, but little attention has been given to this age group especially in regards to evaluating responsivity to different treatment modalities. Contingency management (CM) is a highly effective behavioral treatment that provides positive tangible reinforcers for objective evidence of behavior change. The purpose of this study was to examine main and interactive effects of age on outcomes in cocaine-dependent patients receiving CM with standard care (SC) or SC alone. Patients (N = 393) participating in 1 of 3 randomized trials of CM for cocaine dependence were divided into young, middle, and older age cohorts. Baseline characteristics and outcomes were compared across the age groups. The oldest age group had more medical problems than the youngest and middle age groups but had fewer legal difficulties and psychiatric symptoms. The oldest age group remained in treatment significantly longer than the other age groups, regardless of the type of treatment received. Although all age groups benefited from CM in terms of retention and longest duration of abstinence achieved, a significant age by treatment interaction effect emerged, with the older cohort improving relatively less from CM than the younger age groups. These findings demonstrate that age may play a role in moderating intervention outcomes, and tailoring CM to the needs of older and middle-aged substance abusers may be important for improving outcomes in this growing population.

Social support is associated with gambling treatment outcomes in pathological gamblers.

Poor social support is a contributory factor in development of addictive disorders, but it has rarely been evaluated in pathological gamblers. This study examined social support in pathological gamblers and its relationship with treatment outcomes. Low baseline social support was associated with increased severity of gambling, family, and psychiatric problems and poorer post-treatment outcomes. Further, social support assessed post-treatment was significantly related to severity of gambling problems at the 12-month follow-up. These findings demonstrate that social support plays an important role in moderating outcomes, and enhancing social support may be an important aspect of effective gambling treatments.

Psychometric properties of the inventory of gambling situations with a focus on gender and age differences.

Environmental, interpersonal, and psychological factors contribute to gambling, but no standardized instrument for assessing high-risk gambling situations exists. This study evaluates the factor structure of the Inventory of Gambling Situations (IGS), a newly developed measure to examine situations that precipitate gambling. Pathological gamblers (n = 233) beginning a treatment study completed the IGS. Principal component analysis revealed that a 5-factor solution best fit the data, representing items related to Negative Affect, Luck and Control, Positive Affect, Social Situations, and Gambling Cues. Overall, Cronbach alpha was 0.960, ranging from 0.820 to 0.935 for the 5 factors. IGS scores correlated with other indices of gambling problems. Women scored higher on the Gambling Cues factor than men, and younger respondents, regardless of gender, scored higher on the Luck and Control factor than older respondents. The IGS may assist in better understanding situations in which pathological gamblers wager, and individual differences with respect to these situations.
