ABSTRACT
Childhood poisoning is a prevalent and significant public health issue, with a higher incidence among children under the age of five due to their natural inquisitiveness and impulsive behavior. In order to gain a better understanding of the burden and outcomes of acute poisoning in children, this study utilized data from two comprehensive databases: the 2018 Nationwide Emergency Department Sample and the National (Nationwide) Inpatient Sample. A total of 257,312 hospital visits were analyzed, with 85.5% being emergency department visits and 14.5% being inpatient admissions. Drug overdose emerged as the most commonly known cause of poisoning in both emergency and inpatient settings. While alcohol poisoning was the predominantly known cause of non-pharmaceutical poisoning in the inpatient setting, household soaps and detergents were more common in the emergency setting. Among the identified pharmaceutical agents, non-opioid analgesics and antibiotics were the most frequently implicated. However, a significant proportion of the poisoning cases were caused by unidentified substances (26.8% in the pharmaceutical group and 72.2% in the non-pharmaceutical group). There were 211 deaths in total and further analysis revealed that patients with higher Charlson indices and hospital stays exceeding seven days were associated with increased likelihood of mortality. Additionally, admission to teaching hospitals or hospitals located in the western region of the country was linked to an increased likelihood of an extended hospital stay.
ABSTRACT
BACKGROUND: A large body of research has been conducted on the "weekend effect," which is the reportedly increased risk of adverse outcomes for patients admitted to the hospital on weekends versus those admitted on weekdays. This effect has been researched in numerous patient populations, including sub-populations of end-stage renal disease (ESRD) patients, with varying conclusions. OBJECTIVES: To assess whether differences in in-hospital mortality, access to renal replacement therapy (RRT), time to RRT, and other important outcomes exist in patients with ESRD or patients on RRT admitted on the weekend versus weekdays. DESIGN AND SETTING: A retrospective cohort study was conducted using the 2018 Nationwide Inpatient Sample. Patients were included if they were adults with a principal or secondary diagnosis of ESRD or if they were admitted with a diagnosis related to initiation, maintenance, or complications of RRT. Patients admitted between midnight Friday and midnight Sunday were classified as weekend admissions. Primary outcome measurements included in-hospital mortality, in-hospital dialysis (peritoneal dialysis, hemodialysis, and continuous RRT), and renal transplantation (TP). Secondary outcomes included length of hospital stay (LOS) and total hospitalization charges. RESULTS: The study included 1,144,385 patients who satisfied the inclusion criteria. Compared with patients admitted on weekdays, patients with ESRD admitted on weekends had 8% higher adjusted odds of in-hospital mortality (OR: 1.08; 95% CI: 1.03-1.13; p = 0.002), 9% lower adjusted OR of any RRT over the weekend than on weekdays (OR: 0.91; 95% CI: 0.89-0.93; p = 0.000), lower RRT rates (within 24 hours) (adjusted OR: 0.71; 95% CI: 0.70-0.73; p = 0.000), higher odds of renal TP (adjusted OR: 1.32; 95% CI: 1.20-1.45; p = 0.000), and higher hospitalization charges (mean adjusted increase: $1451; p = 0.07). LIMITATIONS: The limitations of the study include the use of retrospective data and an administrative database. CONCLUSION: Compared with weekday admissions, patients with ESRD admitted on weekends had higher odds of mortality, higher mean hospitalization charges, and higher odds of renal TP. They had lower overall RRT rates, and a longer time to first RRT. However, the average LOS was similar for both weekend and weekday admissions.
