Analysis of factors conditioning inappropriate visits in a paediatric emergency department.

Recent studies estimated that about 20-30% of visits in a paediatric emergency department (PED) are inappropriate. Nonurgent visits have been negatively associated with crowding and costs, causing longer waiting and dissatisfaction among both parents and health workers. We aimed to analyze possible factors conditioning inappropriate visits and misuse in a PED. We performed a cross-sectional study enrolling children accessing an Italian PED from June 2022 to September 2022 who received a nonurgent code. The appropriateness of visits, as measured by the "Mattoni SSN" Project, comprises combination of the assigned triage code, the adopted diagnostic resources, and outcomes. A validated questionnaire was also administered to parents/caregivers of included children to correlate their perceptions with the risk of inappropriate visit. Data were analyzed using independent-samples t-tests, Wilcoxon-Mann-Whitney tests, chi-square tests, and Fisher's exact tests. The factors that were found to be associated with inappropriate visits to the PED were further evaluated by univariable and multivariable logistic regression analyses. Almost half (44.8%) of nonurgent visits resulted inappropriate. Main reasons for parents/caregivers to take their children to PED were (1) the perceived need to receive immediate care (31.5%), (2) the chance to immediately perform exams (26.7%), and (3) the reported difficulty in contacting family paediatrician (26.3%). Inappropriateness was directly related to child's age, male gender, acute illness occurred in the previous month, and skin rash or abdominal pain as complaining symptoms.     Conclusion: This study highlights the urgent need to finalize initiatives to reduce misuse in accessing PED. Empowering parents' awareness and education in the management of the most frequent health problems in paediatric age may help to achieve this goal. What is Known: • About 20-30% of pediatric urgent visits are estimated as inappropriate. • Several factors may be associated with this improper use of the emergency department, such as the misperception of parents who tend to overrate their children's health conditions or dissatisfaction with primary care services. What is New: • This study evaluated almost half of pediatric emergency department visits as inappropriate adopting objective criteria. • Inappropriateness was directly related to the child's age, male gender, acute illness that occurred in the previous month, and skin rash or abdominal pain as complaining symptoms. Educational interventions for parents aimed at improving healthcare resource utilization should be prioritized.

Elevated Intrarenal Resistive Index Predicted Faster Renal Function Decline and Long-Term Mortality in Non-Proteinuric Chronic Kidney Disease.

Background. Intrarenal resistive index (RI) ≥ 0.80 predicts renal outcomes in proteinuric chronic kidney disease (CKD). However, this evidence in non-proteinuric patients with CKD of unknown etiology is lacking. In this study, we assessed the effect of intrarenal RI on renal function and all-cause mortality in non-proteinuric patients with CKD of unknown etiology despite an extensive diagnostic work-up. Methods. Non-proteinuric CKD patients were evaluated in a retrospective longitudinal study. Progression of renal disease was investigated by checking serum creatinine levels at 1, 3, and 5 years and defined by a creatinine level increase of at least 0.5 mg/dL. The discrimination performance of intrarenal RI in predicting the 5-year progression of renal disease was assessed by calculating the area under the receiver operating characteristic curve (AUROC). Results. One-hundred-thirty-one patients (76 ± 9 years, 56% males) were included. The median follow-up was 7.5 years (interquartile range 4.3−10.5) with a cumulative mortality of 53%, and 5-year renal disease progression occurred in 25%. Patients with intrarenal RI ≥ 0.80 had a faster increase of serum creatinine levels compared to those with RI < 0.80 (+0.06 mg/dL each year, 95% CI 0.02−0.10, p < 0.010). Each 0.1-unit increment of intrarenal RI was an independent determinant of 5-year renal disease progression (odds ratio 4.13, 95% CI 1.45−12.9, p = 0.010) and predictor of mortality (hazards ratio 1.80, 95% CI 1.05−3.09, p = 0.034). AUROCs of intrarenal RI for predicting 5-year renal disease progression and mortality were 0.66 (95% CI 0.57−0.76) and 0.67 (95% CI 0.58−0.74), respectively. Conclusions. In non-proteinuric patients with CKD of unknown etiology, increased intrarenal RI predicted both a faster decline in renal function and higher long-term mortality, but as a single marker, it showed poor discrimination performance.
