A Standardized Clinical Pathway to Decrease Hospital Admissions Among Febrile Children With Sickle Cell Disease.

BACKGROUND AND OBJECTIVE: Recurrent hospital admissions for patients with sickle cell disease (SCD) are costly and contribute to a low quality of life for patients. We implemented a clinical pathway to safely discharge SCD patients with fever who are evaluated in the emergency department (ED) of a large tertiary care center. METHODS: An interdisciplinary team of ED and hematology physicians, nurses, and an improvement advisor developed a clinical pathway that identified febrile SCD patients at low risk of serious bacterial infection based on historical, clinical, and laboratory criteria who could be discharged from the ED. Phone follow-up was planned through the use of an automated electronic notification that was sent to an established hematology follow-up pool at the time of ED discharge. We conducted two "fake front end" trials in the ED to receive feedback on our process before full implementation. A postpathway implementation quality improvement team monitored discharge rates, phone follow-up rates and adverse events. RESULTS: In the first 9 weeks postpathway implementation, 100 SCD patients were evaluated for fever; 84 (24%) met low-risk criteria and were discharged home. This reduction in admission rate has been maintained throughout the 3 years postimplementation. Successful phone follow-up was achieved in all discharged patients within 24 hours and no adverse events were identified. CONCLUSIONS: Low-risk febrile patients with SCD can be safely discharged from the ED. An automated notification system within the electronic medical record system can facilitate patient follow-up after ED discharge. Future quality improvement efforts aimed to further reduce admissions in this population should target patients with modifiable risk factors for serious bacterial infection.

Improving Recognition of Pediatric Severe Sepsis in the Emergency Department: Contributions of a Vital Sign-Based Electronic Alert and Bedside Clinician Identification.

STUDY OBJECTIVE: Recognition of pediatric sepsis is a key clinical challenge. We evaluate the performance of a sepsis recognition process including an electronic sepsis alert and bedside assessment in a pediatric emergency department (ED). METHODS: This was a cohort study with quality improvement intervention in a pediatric ED. Exposure was a positive electronic sepsis alert, defined as elevated pulse rate or hypotension, concern for infection, and at least one of the following: abnormal capillary refill, abnormal mental status, or high-risk condition. A positive electronic sepsis alert prompted team assessment or huddle to determine need for sepsis protocol. Clinicians could initiate team assessment or huddle according to clinical concern without positive electronic sepsis alert. Severe sepsis outcome defined as activation of the sepsis protocol in the ED or development of severe sepsis requiring ICU admission within 24 hours. RESULTS: There were 182,509 ED visits during the study period, with 86,037 before electronic sepsis alert implementation and 96,472 afterward, and 1,112 (1.2%) positive electronic sepsis alerts. Overall, 326 patients (0.3%) were treated for severe sepsis within 24 hours. Test characteristics of the electronic sepsis alert alone to detect severe sepsis were sensitivity 86.2% (95% confidence interval [CI] 82.0% to 89.5%), specificity 99.1% (95% CI 99.0% to 99.2%), positive predictive value 25.4% (95% CI 22.8% to 28.0%), and negative predictive value 100% (95% CI 99.9% to 100%). Inclusion of the clinician screen identified 43 additional electronic sepsis alert-negative children, with severe sepsis sensitivity 99.4% (95% CI 97.8% to 99.8%) and specificity 99.1% (95% CI 99.1% to 99.2%). Electronic sepsis alert implementation increased ED sepsis detection from 83% to 96%. CONCLUSION: Electronic sepsis alert for severe sepsis demonstrated good sensitivity and high specificity. Addition of clinician identification of electronic sepsis alert-negative patients further improved sensitivity. Implementation of the electronic sepsis alert was associated with improved recognition of severe sepsis.

Two-Step Process for ED UTI Screening in Febrile Young Children: Reducing Catheterization Rates.

BACKGROUND AND OBJECTIVES: Urinary tract infection (UTI) screening in febrile young children can be painful and time consuming. We implemented a screening protocol for UTI in a high-volume pediatric emergency department (ED) to reduce urethral catheterization, limiting catheterization to children with positive screens from urine bag specimens. METHODS: This quality-improvement initiative was implemented using 3 Plan-Do-Study-Act cycles, beginning with a small test of the proposed change in 1 ED area. To ensure appropriate patients received timely screening, care teams discussed patient risk factors and created patient-specific, appropriate procedures. The intervention was extended to the entire ED after providing education. Finally, visual cues were added into the electronic health record, and nursing scripts were developed to enlist family participation. A time-series design was used to study the impact of the 6-month intervention by using a p-chart to determine special cause variation. The primary outcome measure for the study was defined as the catheterization rate in febrile children ages 6 to 24 months. RESULTS: The ED reduced catheterization rates among febrile young children from 63% to <30% over a 6-month period with sustained results. More than 350 patients were spared catheterization without prolonging ED length of stay. Additionally, there was no change in the revisit rate or missed UTIs among those followed within the hospital's network. CONCLUSIONS: A 2-step less-invasive process for screening febrile young children for UTI can be instituted in a high-volume ED without increasing length of stay or missing cases of UTI.

Renal transplantation into a diverted urinary system-is it safe in children?

PURPOSE: Historically surgeons caring for children with urinary diversion for bladder outlet obstruction have routinely performed undiversion before renal transplantation. We hypothesized that patients undergoing transplantation into a diverted system would have outcomes similar to those undergoing transplantation into a normal bladder. We review the outcomes of patients with and without diversion undergoing kidney transplantation at our institution. MATERIALS AND METHODS: We retrospectively studied a cohort of children undergoing renal transplant between 1993 and 2006. Patients whose etiology of end-stage renal disease was either obstructive uropathy or renal dysplasia were included. Patients with less than 5 years of followup were excluded from the analysis. Four groups were assembled, ie controls with renal dysplasia and no history of obstructive uropathy undergoing transplant (group 1), patients with obstructive uropathy not diverted at transplant (group 2), patients with obstructive uropathy diverted at transplant (group 3) and patients with obstructive uropathy augmented before transplant (group 4). The groups were compared for outcomes of frequency of urinary tract infection, renal graft function and graft loss. RESULTS: Of the 80 subjects eligible based on diagnostic criteria 43 had completed 5 years of followup. There was no significant difference between groups based on age (p = 0.508), renal function as measured by glomerular filtration rate (p = 0.526) or creatinine (p = 0.612), or frequency of urinary tract infections (p = 0.083). Only 1 patient in the cohort suffered graft loss. CONCLUSIONS: Based on frequency of urinary tract infection, renal function and graft loss 5 years after transplant, there appears to be no added risk to transplanting a kidney into a diverted system.

Histological examination of solitary contralateral descended testis in congenital absence of testis.

PURPOSE: Congenital absence of the testis is believed to be secondary to prenatal torsion, differing from the isolated undescended testis. We determined whether congenital absence of the testis is associated with abnormal histology in the solitary contralateral descended testis. MATERIALS AND METHODS: A total of 239 boys with a primary diagnosis of unilateral absent testis underwent orchiectomy and testis biopsy. Germ cell counts were compared between solitary contralateral descended testes and contralateral descended testes in a randomly selected, age matched cohort of patients with unilateral undescended testes. Subanalyses evaluating hypertrophic testes and hypertrophic prepubertal testes between the study groups were performed. RESULTS: The solitary contralateral descended testis group exhibited a significantly greater volume (p <0.001) and a significantly greater germ cell count (p = 0.001). In the hypertrophied testes there was a greater gonocyte count (p = 0.02), greater percentage of gonocytes (p = 0.02), greater primary spermatocyte count (p = 0.04) and greater percentage of primary spermatocytes (p = 0.03). No significant differences in adult dark spermatogonia or Leydig cells were detected. Primary spermatocytes did not differ significantly in prepubertal patients. CONCLUSIONS: The solitary contralateral descended testis exhibits increased volume, increased germ cell proliferation and dissimilar maturation patterns compared to the contralateral descended testis in unilateral cryptorchidism. These findings support prenatal torsion rather than endocrinopathy as the etiology for the congenitally absent testis. In the postpubertal solitary contralateral descended testis more germ cell maturation is seen and primary spermatocytes account for the increased total germ cell count. Patients with a solitary testis are likely not at additional risk for infertility.

Children with disorders of sex development: A qualitative study of early parental experience.

BACKGROUND: Clinical research on psychological aspects of disorders of sex development (DSD) has focused on psychosexual differentiation with relatively little attention directed toward parents' experiences of early clinical management and their influence on patient and family psychosocial adaptation. OBJECTIVES: To characterize parental experiences in the early clinical care of children born with DSD. STUDY DESIGN: Content analysis of interviews with parents (n = 41) of 28 children, newborn to 6 years, with DSD. RESULTS: Four major domains emerged as salient to parents: (1) the gender assignment process, (2) decisions regarding genital surgery, (3) disclosing information about their child's DSD, and (4) interacting with healthcare providers. Findings suggested discordance between scientific and parental understandings of the determinants of "sex" and "gender." Parents' expectations regarding the benefits of genital surgery appear largely met; however, parents still had concerns about their child's future physical, social and sexual development. Two areas experienced by many parents as particularly stressful were: (1) uncertainties regarding diagnosis and optimal management, and (2) conflicts between maintaining privacy versus disclosing the condition to access social support. CONCLUSIONS: Parents' experiences and gaps in understanding can be used to inform the clinical care of patients with DSD and their families. Improving communication between parents and providers (and between parents and their support providers) throughout the early clinical management process may be important in decreasing stress and improving outcomes for families of children with DSD.

Pediatric psychology in genitourinary anomalies.

Children with genitourinary anomalies are at risk for developmental and adjustment challenges. Pediatric psychologists can address the needs of these children within the urology clinic through focusing on assessment, intervention, and prevention of psychosocial problems associated with their urologic diagnosis. Care is optimized if surgeons and mental health providers work together to care for this challenging group of patients.

Quantifying demographic, urological and behavioral characteristics of children with lower urinary tract symptoms.

OBJECTIVE: This project examines the voiding and behavioral characteristics of children referred to a specialty voiding clinic, including the impact of incontinence on the child and family. PATIENTS AND METHODS: A total of 351 new patients (aged 5-17 years) referred to our specialty voiding clinic completed background information, including demographics and medical history, a standardized voiding questionnaire, school history, and questions about child and family quality of life, prior to their first appointment. RESULTS: Patients are primarily female (53%) and Caucasian (70%) with a mean age of 9.5 years (range 5-17; SD=3.5). Of the patients, 25% were diagnosed with a mental or behavioral health problem. Mean urological symptom score was 12 (range 0-29). Higher symptom scores are associated with younger age, ethnic minority status, a mental health diagnosis, being on psychotropic medications, and a poor child and family quality of life. Families of children who are wet day and night reported a poorer quality of life as compared to the families of children who were daytime wetters or bedwetters only. CONCLUSION: Symptom scores are associated with type of incontinence, social and quality of life variables. Collecting this baseline data will enable ongoing monitoring of progress for these complex patients.

Eliciting accurate reports of adherence in a clinical interview: development of the Medical Adherence Measure.

Nonadherence is a major public health concern but reliable assessment methods are limited. The Medical Adherence Measure (MAM) was designed as a semi-structured clinical interview to elicit comprehensive and accurate responses from patients regarding adherence during the course of standard clinical care. The measure was developed in three phases and administered to 219 pediatric patients (ages 1.3-23) and/or their parents to assess the content, clinical utility, and ease of use. The MAM has three general regimen domains (medication, diet, clinic attendance) and several treatment specific modules. Items assess knowledge of the prescribed regimen, self-reported adherence, organizational system used to manage the regimen, and perceived barriers to optimal management. The MAM is a screening tool that assists providers in identifying patients at risk for adherence problems, assessing the extent of nonadherence, and targeting specific barriers to care in interventions. The interview emphasizes a supportive patient-provider relationship with the goal of improving patient care.

Perceived barriers to adherence among adolescent renal transplant candidates.

Non-adherence to medical regimens is a ubiquitous hindrance to quality health care among adolescent transplant recipients. Identification of potentially modifiable barriers to adherence when patients are listed for organ transplant would help with early intervention efforts to prepare adolescents for the stringent medication regimen post-transplant. Fifty-six adolescents listed for a kidney transplant, mean age 14.27 (s.d. = 2.2; range 11-18 yr), 73.2% male, 62.5% Caucasian participated in a semi-structured interview, the Medical Adherence Measure, to assesses the patient's knowledge of the prescribed regimen, reported adherence (missed and late doses), the system used to organized medications, and who holds the primary responsibility over medication management. Better knowledge of the medication regimen was associated with fewer missed doses (r = -0.48, p < 0.001). Patients who perceived more barriers had more missed (r = 0.38, p = 0.004) and late (r = 0.47, p < 0.001) doses. Patients who endorsed "just forget," the most common barrier (56.4%), reported significantly more missed (z = -4.25, p < 0.001) and late (z = -2.2, p = 0.02) doses. Only one-third of the transplant candidates used a pillbox to organize medications but these patients had significantly better adherence, z = -2.2, p = 0.03. With regard to responsibility over managing the regimens, adolescents missed fewer doses when their parents were in charge than when they were solely responsible, z = -2.1, p = 0.04. Interventions developed to prepare transplant candidates for a stringent post-transplant regimen need to focus on ensuring accurate knowledge of as simple a regimen as possible. Use of an organized system such as a pillbox to establish a routine and facilitate tracking of medications is recommended with integration of reminders that may be appealing for this age group. Although individuation is developmentally normative at this age, parent involvement seems critical until the adolescent is able to manage the responsibility more independently.
