Imaging Practices and Implications in Young Infants With Urinary Tract Infection.

OBJECTIVES: Management of infants aged ≤60 days with urinary tract infections (UTI) is challenging. We examined renal imaging in infants aged ≤60 days with UTI at a tertiary care children's hospital to identify the impact of standardizing renal ultrasound (RUS) interpretation. METHODS: We retrospectively studied infants aged ≤60 days hospitalized for UTI or fever with urine culture and renal imaging obtained and final diagnosis of UTI. RUS initially had noncriterion-based (NCB) interpretation by experienced pediatric radiologists. For this study, a single pediatric radiologist used a criterion-based (CB) hydronephrosis grading system to reinterpret films initially classified as "abnormal" on the NCB reading. We compared final renal imaging results between NCB and CB groups. RESULTS: Of 193 infants, 180 (93%) had inpatient RUS with 114 (63%) abnormal NCB interpretation. Of those with initially abnormal NCB interpretation, 85 OF 114 (75%) had minor and 29 OF 114 (25%) had significant abnormality by CB reinterpretation. In follow-up, the CB "minor abnormality" group showed 25% abnormal renal imaging, whereas the "significant abnormality" group showed 77% abnormal renal imaging with 54% having high-grade reflux on a voiding cystourethrogram (VCUG). Patients with CB inpatient RUS minor abnormality showed 3% abnormal RUS at follow-up, but 13% showed high-grade reflux on VCUG. CONCLUSIONS: Standardized RUS interpretation in young infants with UTI improved the accuracy of identification of abnormalities on follow-up renal imaging. In patients with CB minor abnormality on inpatient RUS, our results suggest limited utility of follow-up RUS; however, follow-up VCUG remained useful to identify high-grade reflux.

MedCDI: A technology-based documentation and quality improvement initiative in neurosurgery.

Background: Clinical documentation of patient care alters coding accuracy of Medicare Severity Diagnosis-Related Groups (MS-DRGs), expected mortality, and expected length of stay (LOS) which impact quality metrics. We aimed to determine if neurosurgical quality metrics could be improved by facilitating accurate documentation and subsequently developed a mobile application and educational video to target areas of opportunity. Methods: Vizient software was used to analyze MS-DRGs and expected LOS for sample of patients requiring surgery for spinal pathology, brain tumors, and subarachnoid hemorrhage (SAH) between January 2019 and August 2021. Chart reviews were conducted to discover variables missed by documenting provider and/or coder. Results: Review of 114 spinal surgeries, 20 brain tumors, and 53 SAH patients revealed at least one additional variable impacting LOS in 43% of spine, 75% of brain tumor, and 92% of SAH patients, with an average of 1 (1.25), 2 (1.75), and 3 (2.89) new variables, respectively. Recalculated expected LOS increased by an average of 0.86 days for spine, 3.08 for brain tumor, and 6.46 for SAH cases. Conclusion: Efforts to accurately document patient care can improve quality metrics such as expected LOS, mortality, and cost estimates. We determined several missing variables which impact quality metrics, showing opportunity exists in neurosurgical documentation improvement. Subsequently, we developed an educational video and mobile-supported application to specifically target these variables. To the best of our knowledge, this represents the first initiative to utilize the proven powers of mobile phones in health care toward the novel application of specifically improving neurosurgical quality metrics.

Bone Marrow Suppression Associated With Celiac Disease in a 4-Year-Old Boy.

Celiac disease is an immune-mediated process against gluten, resulting in inflammation and villous atrophy of the duodenum. Symptoms of malabsorption characterize the classic presentation; however, abdominal pain, constipation, and nutritional deficiencies can also be seen. We present a case of a 4-year-old boy who was found to have celiac disease after presenting with diarrhea, abdominal pain, weight loss, and new-onset pancytopenia. Symptoms resolved, and laboratory values normalized after the initiation of a gluten-free diet, indicating the bone marrow suppression was due to celiac disease, which needs to be considered when hematologic abnormalities are present, even in the absence of gastrointestinal symptoms.

COVID-19 Experience in a Wisconsin Academic Medical Center.

BACKGROUND: Several studies describing Coronavirus disease 2019 (COVID-19) have been reported; however, to our knowledge, no case series has been published from the Midwest. OBJECTIVE: To describe demographic characteristics and outcomes of patients admitted with COVID-19 to a Wisconsin academic medical center. METHODS: We performed a retrospective analysis of data obtained for COVID-19 patients admitted from March 14, 2020, through April 19, 2020. RESULTS: One hundred sixty-eight patients were admitted. Outcomes measured include time in the intensive care unit (53%), mechanical ventilation (18%), and death (19%). ICU patients had higher rates of diabetes, obesity, and higher inflammatory markers. The majority of patients admitted were African American (68%). CONCLUSION: This case series highlights demographic similarities and differences, as well as outcomes, among COVID-19 patients in a Wisconsin Academic Medical Center compared to those reported in other geographic regions.

Urinary Tract Infection in Young Infants: Practice Patterns in Evaluation and Treatment.

OBJECTIVES: No clear guidelines exist for the management of infants ≤60 days old with urinary tract infection (UTI), although this condition represents a significant percentage of serious bacterial infection in this age group. We examined patterns of UTI management in infants ≤60 days at a tertiary care children's hospital and hypothesized that younger infants would be hospitalized longer. METHODS: We reviewed electronic health records of infants age ≤60 days with diagnostic codes of UTI or fever hospitalized from January 2013 to January 2017 with urine culture obtained and UTI diagnosis documented. Outcomes were duration of parenteral antibiotic therapy, length of stay (LOS), and hospital readmission. RESULTS: One hundred ninety-three infants met criteria. Median age at admission was 37 days (interquartile range [IQR]: 22-48). Median duration of parenteral antibiotics was 59 hours (IQR 43-114) and median LOS was 71 hours (IQR 57 127). Infants age ≤28 days, with fever duration ≥24 hours, irritability or lethargy on initial examination, and bacteremia received longer parenteral therapy and had longer LOS. In multivariate analysis, age, irritability or lethargy, and presence of bacteremia remained independently related to parenteral therapy duration and LOS. CONCLUSIONS: In young infants with UTI, patients aged ≤28 days had longer duration of IV antibiotic therapy and LOS, independent of other clinical characteristics of their illness. The duration of parenteral therapy and LOS was relatively short, although significant variability still existed.

Factors Associated With HSV PCR CSF Testing and Empiric Acyclovir Therapy in Young Febrile Infants.

Herpes simplex virus (HSV) infection in infants is a devastating disease with an often subtle presentation. We examined cerebrospinal fluid (CSF) HSV PCR (polymerase chain reaction) testing and empiric acyclovir therapy in young febrile infants. Chart review identified hospitalized infants aged ≤60 days with fever ≥38°C who had undergone lumbar puncture. Previously published criteria were used to define patients at high risk for HSV. Primary outcomes were CSF HSV PCR testing and empiric acyclovir therapy. Of 536 febrile infants, 23% had HSV testing; empiric acyclovir was started in 15%. HSV testing and therapy were associated with younger age, seizure, maternal vaginal lesions, postnatal HSV contact, vesicles, poor tone, CSF pleocytosis, and enteroviral testing. Sixty-two percent of high-risk infants did not undergo HSV testing, and 75% did not receive acyclovir. High-risk infants were untested and untreated at relatively high rates. Evidence-based criteria to guide HSV testing and treatment are needed.
