RESUMEN

BACKGROUND: In the hospitalized patient, nephrotoxin exposure is one potentially modifiable risk factor for acute kidney injury (AKI). Clinical decision support based on nephrotoxin ordering was developed at our hospital to assist inpatient providers with the prevention or mitigation of nephrotoxin-related AKI. The initial decision support algorithm (Algorithm 1) was modified in order to align with a national AKI collaborative (Algorithm 2). OBJECTIVE: Our first aim was to determine the impact of this alignment on the sensitivity and specificity of our nephrotoxin-related AKI detection system. Second, if the system efficacy was found to be suboptimal, we then sought to develop an improved model. DESIGN: A retrospective cohort study in hospitalized patients between December 1, 2013 and November 30, 2015 (N = 14,779) was conducted. INTERVENTIONS: With the goal of increasing nephrotoxin-related AKI detection sensitivity, a novel model based on the identification of combinations of high-risk medications was developed. RESULTS: Application of the algorithms to our nephrotoxin use and AKI data resulted in sensitivities of 46.9% (Algorithm 1) and 43.3% (Algorithm 2, P = .22) and specificities of 73.6% and 89.3%, respectively (P < .001). Our novel AKI detection model was able to deliver a sensitivity of 74% and a specificity of 70%. CONCLUSIONS: Modifications to our AKI detection system by adopting Algorithm 2, which included an expanded list of nephrotoxins and equally weighting each medication, did not improve our nephrotoxin-related AKI detection. It did improve our system's specificity. Sensitivity increased by >50% when we applied a novel algorithm based on observed data with identification of key medication combinations.

RESUMEN

OBJECTIVE: Efforts to decrease hospital revisits often focus on improving access to outpatient follow-up. Our objective was to assess the relationship between perceived access to timely office-based care and subsequent 30-day revisits following hospital discharge for 4 common respiratory illnesses. METHODS: This was a prospective cohort study of children 2 weeks to 16years admitted to 5 US children's hospitals for asthma, bronchiolitis, croup, or pneumonia between July 2014 and June 2016. Hospital and emergency department (ED) (in the case of croup) admission surveys administered to caregivers included the Consumer Assessments of Healthcare Providers and Systems Timely Access to Care. Access composite scores (range 0-100, with greater scores indicating better access) were linked with 30-day ED revisits and inpatient readmissions from the Pediatric Health Information System. The relationship between access to timely care and repeat utilization was assessed using multivariable logistic regression adjusting for demographics, hospitalization, and home/outpatient factors. RESULTS: Of the 2438 children enrolled, 2179 (89%) reported an office visit in the previous 6 months. Average access composite score was 52.0 (standard deviation, 36.3). In adjusted analyses, greater access scores were associated with greater odds of 30-day ED revisits (odds ratio [OR] = 1.07; 95% confidence interval [CI], 1.02-1.13)-particularly for croup (OR = 1.17; 95% CI, 1.02-1.36)-but not inpatient readmissions (OR = 1.02; 95% CI, 0.96-1.09). CONCLUSIONS: Perceived access to timely office-based care was associated with significantly greater odds of subsequent ED revisit. Focusing solely on enhancing timely access to care following discharge for common respiratory illnesses may be insufficient to prevent repeat utilization.

RESUMEN

OBJECTIVES: Seattle Children's Hospital sought to optimize the value equation for neonatal jaundice patients by creating a standard care pathway. METHODS: An evidence-based pathway for management of neonatal jaundice was created. This included multidisciplinary team assembly, comprehensive literature review, creation of a treatment algorithm and computer order sets, formulation of goals and metrics, roll-out of an education program for end users, and ongoing pathway improvement. The pathway was implemented on May 31, 2012. Quality metrics before and after implementation were compared. External data were used to analyze cost impacts. RESULTS: Significant improvements were achieved across multiple quality dimensions. Time to recovery decreased: mean length of stay was 1.30 days for 117 prepathway patients compared with 0.87 days for 69 postpathway patients (P < .001). Efficiency was enhanced: mean time to phototherapy initiation was 101.26 minutes for 14 prepathway patients compared with 54.67 minutes for 67 postpathway patients (P = .03). Care was less invasive: intravenous fluid orders were reduced from 80% to 44% (P < .001). Inpatient use was reduced: 66% of prepathway patients were admitted from the emergency department to inpatient care, compared with 50% of postpathway patients (P = .01). There was no increase in the readmission rate. These achievements translated to statistically significant cost reductions in total charges, as well as in the following categories: intravenous fluids, laboratory, room cost, and emergency department charges. CONCLUSIONS: An evidence-based standard care pathway for neonatal jaundice can significantly improve multiple dimensions of value, including reductions in cost and length of stay.

RESUMEN

OBJECTIVES: High-flow nasal cannula (HFNC) use has increased in patients with bronchiolitis, with the majority of use restricted to the ICU. Broadening HFNC to the wards may have substantial economic implications. This study compares the cost of a standardized clinical pathway that permits HFNC use in the wards for patients with bronchiolitis with an ICU-only HFNC care model. METHODS: We constructed a decision analytic model to simulate 2 options for treating bronchiolitic patients: one in which HFNC is used in the wards (ward HFNC) and one in which HFNC is restricted to the ICU (ICU HFNC). The model inputs were based on patients admitted with bronchiolitis without major comorbidities between 2010 and 2015. 1432 patients were included for analysis. We simulated 10 000 patients for 5000 trials to assess parameter variability and sampling uncertainty, respectively. The primary outcome was average admission cost per patient. The secondary outcome was average length of stay (LOS) per patient. RESULTS: In the model, the average admission cost per patient for the ward HFNC group was $7020 (95% confidence interval [CI] $6840-$7194) compared with $7626 (95% CI $7427-$7839) in the ICU HFNC group, with a net difference of $606 (95% CI $408-$795). The average LOS for the ward HFNC group was 2.29 days (95% CI 2.24-2.33) compared with 2.61 days (95% CI 2.56-2.66) in the ICU HFNC group, with a net difference of 0.32 days (95% CI 0.27-0.37). CONCLUSIONS: Using HFNC in the ward for bronchiolitis may be cost-effective and may decrease LOS compared with ICU-only HFNC.

RESUMEN

OBJECTIVE: In this report, we aim to describe the epidemiology of extended-spectrum cephalosporin-resistant (ESC-R) and carbapenem-resistant (CR) Enterobacteriaceae infections in children. METHODS: ESC-R and CR Enterobacteriaceae isolates from normally sterile sites of patients aged <22 years from 4 freestanding pediatric medical centers were collected along with the associated clinical data. RESULTS: The overall frequencies of ESC-R and CR isolates according to hospital over the 4-year study period ranged from 0.7% to 2.8%. Rates of ESC-R or CR Escherichia coli and Klebsiella pneumoniae varied according to hospital and ranged from 0.75 to 3.41 resistant isolates per 100 isolates (P < .001 for any differences). E coli accounted for 272 (77%) of the resistant isolates; however, a higher rate of resistance was observed in K pneumoniae isolates (1.78 vs 1.27 resistant isolates per 100 same-species isolates, respectively; P = .005). One-third of the infections caused by ESC-R or CR E coli were community-associated. In contrast, infections caused by ESC-R or CR K pneumoniae were more likely than those caused by resistant E coli to be healthcare- or hospital-associated and to occur in patients with an indwelling device (P ≤ .003 for any differences, multivariable logistic regression). Nonsusceptibility to 3 common non-ß-lactam agents (ciprofloxacin, gentamicin, and trimethoprim-sulfamethoxazole) occurred in 23% of the ESC-R isolates. The sequence type 131-associated fumC/fimH-type 40-30 was the most prevalent sequence type among all resistant E coli isolates (30%), and the clonal group 258-associated allele tonB79 was the most prevalent allele among all resistant K pneumoniae isolates (10%). CONCLUSIONS: The epidemiology of ESC-R and CR Enterobacteriaceae varied according to hospital and species (E coli vs K pneumoniae). Both community and hospital settings should be considered in future research addressing pediatric ESC-R Enterobacteriaceae infection.

RESUMEN

OBJECTIVE: To identify insurance-based disparities in access to outpatient pediatric neurorehabilitation services. DESIGN: Audit study with paired calls, where callers posed as a mother seeking services for a simulated child with history of severe traumatic brain injury and public or private insurance. SETTING: Outpatient rehabilitation clinics. PARTICIPANTS: Sample of rehabilitation clinics (N=287): 195 physical therapy (PT) clinics, 109 occupational therapy (OT) clinics, 102 speech therapy (ST) clinics, and 11 rehabilitation medicine clinics. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Acceptance of public insurance and the number of business days until the next available appointment. RESULTS: Therapy clinics were more likely to accept private insurance than public insurance (relative risk [RR] for PT clinics, 1.33; 95% confidence interval [CI], 1.22-1.44; RR for OT clinics, 1.40; 95% CI, 1.24-1.57; and RR for ST clinics, 1.42; 95% CI, 1.25-1.62), with no significant difference for rehabilitation medicine clinics (RR, 1.10; 95% CI, 0.90-1.34). The difference in median wait time between clinics that accepted public insurance and those accepting only private insurance was 4 business days for PT clinics and 15 days for ST clinics (P≤.001), but the median wait time was not significantly different for OT clinics or rehabilitation medicine clinics. When adjusting for urban and multidisciplinary clinic statuses, the wait time at clinics accepting public insurance was 59% longer for PT (95% CI, 39%-81%), 18% longer for OT (95% CI, 7%-30%), and 107% longer for ST (95% CI, 87%-130%) than that at clinics accepting only private insurance. Distance to clinics varied by discipline and area within the state. CONCLUSIONS: Therapy clinics were less likely to accept public insurance than private insurance. Therapy clinics accepting public insurance had longer wait times than did clinics that accepted only private insurance. Rehabilitation professionals should attempt to implement policy and practice changes to promote equitable access to care.

RESUMEN

BACKGROUND AND OBJECTIVE: Cyclophosphamide is a teratogenic medication used in the treatment of adolescents with autoimmune disorders. This adolescent population is sexually active, does not receive adequate contraceptive care, and is at risk for unintended pregnancy. We undertook a quality improvement initiative to improve rates of pregnancy screening before intravenous cyclophosphamide administration in our adolescent girl patients. METHODS: Data were collected from the electronic medical record. The primary outcome was completion of a urine pregnancy test before intravenous cyclophosphamide infusion in girls aged 12 to 21 years between July 2011 and June 2015. Data were reviewed quarterly and an iterative quality improvement approach was used. Interventions included staff education, electronic order set updates, and a Maintenance of Certification project. Interrupted time series analysis and multivariable mixed effects logistic regression were used to evaluate trends over time and to adjust for potential confounders. RESULTS: Thirty girls received 153 cyclophosphamide infusions during the study. Pregnancy testing before medication administration increased from 25% to 100% by study completion. Infusions in the last time period were significantly more likely to be accompanied by a pregnancy test versus those in the first time period (odds ratio: 17.7; 95% confidence interval [CI]: 3.1-101.6) after adjustment for patient age, managing service, infusion setting, and insurance type. CONCLUSIONS: Our institution achieved a significant increase in standard pregnancy screening in adolescent girls receiving intravenous cyclophosphamide. The interventions most valuable in increasing screening rates were updating electronic order sets, educating staff, and physician engagement in the Maintenance of Certification program.

RESUMEN

This study tested potential moderators and mediators of an indicated depression prevention program for middle school students, Positive Thoughts and Actions (PTA). Participants were 120 students randomly assigned to PTA, or a brief, individually administered supportive intervention (Individual Support Program, or ISP). Youths completed measures of depressive symptoms at baseline, post-intervention, and 12-month follow-up. Hierarchical regression was used to test three moderators-ethnic minority status, gender, and baseline depressive symptoms-and three mediators representing functional outcomes targeted by PTA-parent-child communication, attitude towards school, and health behavior. Ethnic minority status did not moderate PTA effects at post-intervention but did moderate PTA effects at 12-month follow-up. At 12 months, PTA appeared to be more effective for White participants than ethnic minority youth. Follow-up analyses suggested this moderation effect was due to the tendency of ethnic minority youth, especially those with fewer symptoms at baseline, to drop out by 12 months. Neither gender nor baseline depressive symptoms moderated the effects of PTA. Although PTA improved health behavior and attitudes toward school, there was no evidence that any of these functional outcomes measured mediated the impact of PTA on depressive symptoms. Future directions are discussed.

RESUMEN

Importance: Depression is one of the most common adolescent chronic health conditions and can lead to increased health care use. Collaborative care models have been shown to be effective in improving adolescent depressive symptoms, but there are few data on the effect of such a model on costs. Objective: To evaluate the costs and cost-effectiveness of a collaborative care model for treatment of adolescent major depressive disorder in primary care settings. Design, Setting, and Participants: This randomized clinical trial was conducted between April 1, 2010, and April 30, 2013, at 9 primary care clinics in the Group Health system in Washington State. Participants were adolescents (age range, 13-17 years) with depression who participated in the Reaching Out to Adolescents in Distress (ROAD) collaborative care intervention trial. Interventions: A 12-month collaborative care intervention included an initial in-person engagement session, delivery of evidence-based treatments, and regular follow-up by master's level clinicians. Youth in the usual care control condition received depression screening results and could access mental health services and obtain medications through Group Health. Main Outcomes and Measures: Cost outcomes included intervention costs and per capita health plan costs, calculated from the payer perspective using administrative records. The primary effectiveness outcome was the difference in quality-adjusted life-years (QALYs) between groups from baseline to 12 months. The QALYs were calculated using Child Depression Rating Scale-Revised scores measured during the clinical trial. Cost and QALYs were used to calculate an incremental cost-effectiveness ratio. Results: Of those screened, 105 youths met criteria for entry into the study, and 101 were randomized to the intervention (n = 50) and usual care (n = 51) groups. Overall health plan costs were not significantly different between the intervention ($5161; 95% CI, $3564-$7070) and usual care ($5752; 95% CI, $3814-$7952) groups. Intervention delivery cost an additional $1475 (95% CI, $1230-$1695) per person. The intervention group had a mean daily utility value of 0.78 (95% CI, 0.75-0.80) vs 0.73 (95% CI, 0.71-0.76) for the usual care group. The net mean difference in effectiveness was 0.04 (95% CI, 0.02-0.09) QALY at $883 above usual care. The mean incremental cost-effectiveness ratio was $18 239 (95% CI, dominant to $24 408) per QALY gained, with dominant indicating that the intervention resulted in both a net cost savings and a net increase in QALYs. Conclusions and Relevance: Collaborative care for adolescent depression appears to be cost-effective, with 95% CIs far below the strictest willingness-to-pay thresholds. These findings support the use of collaborative care interventions to treat depression among adolescent youth. Trial Registration: clinicaltrials.gov Identifier: NCT01140464.

RESUMEN

BACKGROUND: A key strategy to reduce unintended adolescent pregnancies is to expand access to long-acting reversible contraceptive (LARC) methods, including intrauterine devices and subdermal contraceptive implants. LARC services can be provided to adolescents in school-based health and other primary care settings, yet limited knowledge and negative attitudes about LARC methods may influence adolescents' utilization of these methods. This study aimed to evaluate correlates of knowledge and acceptability of LARC methods among adolescent women at a school-based health center (SBHC). METHODS: In this cross-sectional study, female patients receiving care at 2 SBHCs in Seattle, Washington completed an electronic survey about sexual and reproductive health. Primary outcomes were (1) LARC knowledge as measured by percentage correct of 10 true-false questions and (2) LARC acceptability as measured by participants reporting either liking the idea of having an intrauterine device (IUD)/subdermal implant or currently using one. RESULTS: A total of 102 students diverse in race/ethnicity and socioeconomic backgrounds completed the survey (mean age 16.2 years, range 14.4-19.1 years). Approximately half reported a lifetime history of vaginal sex. Greater LARC knowledge was associated with white race (regression coefficient [coef] = 26.8; 95% CI 13.3-40.4; P < .001), history of vaginal intercourse (coef = 29.9; 95% CI 17.1-42.7; P < .001), and current/prior LARC use (coef = 22.8; 95% CI 6.5-40.0; P = .007). Older age was associated with lower IUD acceptability (odds ratio = 0.53, 95% CI 0.30-0.94; P = .029) while history of intercourse was associated with greater implant acceptability (odds ratio 5.66, 95% CI 1.46-22.0; P = .012). DISCUSSION: Adolescent women in this SBHC setting had variable knowledge and acceptability of LARC. A history of vaginal intercourse was the strongest predictor of LARC acceptability. Our findings suggest a need for LARC counseling and education strategies, particularly for young women from diverse cultural backgrounds and those with less sexual experience.

RESUMEN

OBJECTIVE: To assess how parents perceive long-term risks for developing obesity-related chronic health conditions. METHODS: A Web-based nationally representative survey was administered to 502 US parents with a 5- to 12-year-old child. Parents reported whether their child was most likely to be at a healthy weight or overweight, and the probability that their child would develop hypertension, heart disease, depression, or type 2 diabetes in adulthood. Responses of parents of children with overweight and obesity were compared to those of healthy-weight children using multivariate models. RESULTS: The survey had an overall response rate of 39.2%. The mean (SD) unadjusted parent predicted health risks were 15.4% (17.7%), 11.2% (14.7%), 12.5% (16.2%), and 12.1% (16.1%) for hypertension, heart disease, depression, and diabetes, respectively. Despite underperceiving their child's current body mass index class, parents of children with obesity estimate their children to be at greater risk for obesity-related health conditions than parents of healthy-weight children by 5 to 6 percentage points. Having a family history of a chronic disease, higher quality of care, and older parent age were also significant predictors of estimating higher risk probabilities. CONCLUSIONS: Despite evidence that parents of children who are overweight may not perceive these children as being overweight, parents unexpectedly estimate greater future risk of weight-related health conditions for these children. Focusing communication about weight on screening for and reducing the risk of weight-related diseases may prove useful in engaging parents and children in weight management.

RESUMEN

INTRODUCTION: According to 40 yr of data, the fatality rate for a helicopter crash into water is approximately 25%. Does warning time and the final position of the helicopter in the water influence the survival rate? METHODS: The National Transportation Safety Board (NTSB) database was queried to identify helicopter crashes into water between 1981 and 2011 in the Gulf of Mexico and Hawaii. Fatality rate, amount of warning time prior to the crash, and final position of the helicopter were identified. RESULTS: There were 133 helicopters that crashed into water with 456 crew and passengers. Of these, 119 occupants (26%) did not survive; of those who did survive, 38% were injured. Twelve died after making a successful escape from the helicopter. Crashes with < 15 s warning had a fatality rate of 22%, compared to 12% for 16-60 s warning and 5% for > 1 min. However, more than half of fatalities (57%) came from crashes for which the warning time could not be determined. DISCUSSION: Lack of warning time and how to survive in the water after the crash should be a topic for study in all marine survival/aircraft ditching courses. Investigators should be trained to provide estimates of warning time when investigating helicopter crashes into water.

RESUMEN

INTRODUCTION: Crashes of sightseeing helicopter flights in Hawaii and the resulting tourist deaths prompted the FAA to issue regulations in 1994 specific to air tours in Hawaii. Research was undertaken to examine the effect of the 1994 Rule and to describe the circumstances of such crashes. METHOD: From National Transportation Safety Board data, 59 crashes of helicopter air tour flights in Hawaii during 1981-2008 were identified; crash investigation reports were read and coded. Crashes in 1995-2008 were compared with those in 1981-1994. RESULTS: The 1994 Rule was followed by a 47% decrease in the crash rate, from 3.4 to 1.8/100,000 flight hours. The number of crashes into the ocean decreased from eight before the Rule to one afterwards. VFR-IMC crashes increased from 5 to 32% of crashes. There were 46 tourists and 9 pilots who died in 16 fatal crashes. Aircraft malfunctions, primarily due to poor maintenance, precipitated 34 (58%) of the crashes and persisted throughout the 28-yr period. Pilot errors were apparent in 23 crashes (39%). Flight from visual to instrument conditions occurred in two cases before the Rule and seven cases after. Terrain unsuitable for landing was cited in 37 crashes (63%). CONCLUSION: Decreases occurred in the overall number and rate of crashes and in ocean crash landings. The increase in VFR-IMC crashes may be related to the requirement that tour helicopters fly at least 1500 ft. above terrain. Attention is still needed to maintenance, pilot training, and restricting flights to operating areas and conditions that enable safe emergency landings.
