Objectives

To evaluate readmission rates and associated factors to identify potentially preventable readmissions.

Background

The decision to penalize hospitals for readmissions is compelling health care systems to develop processes to minimize readmissions. Research to identify preventable readmissions is critical to achieve these goals.

Methods

We performed a retrospective review of University HealthSystem Consortium database for cancer patients hospitalized from January 2010 to September 2013. Outcome measures were 7-, 14-, and 30-day readmission rates and readmission diagnoses. Hospital and disease characteristics were evaluated to evaluate relationships with readmission.

Results

A total of 2,517,886 patients were hospitalized for cancer treatment. Readmission rates at 7, 14, and 30 days were 2.2%, 3.7%, and 5.6%, respectively. Despite concern that premature hospital discharge may be associated with increased readmissions, a shorter initial length of stay predicted lower readmission rates. Furthermore, high-volume centers and designated cancer centers had higher readmission rates. Evaluating institutional data (N = 2517 patients) demonstrated that factors associated with higher readmission rates include discharge from a medical service, site of malignancy, and emergency primary admission. When examining readmission within 7 days for surgical services, the most common readmission diagnoses were infectious causes (46.3%), nausea/vomiting/dehydration (26.8%), and pain (6.1%).

Conclusions

A minority of patients after hospitalization for cancer-related therapy are readmitted with potentially preventable conditions such as nausea, vomiting, dehydration, and pain. However, most factors associated with readmission cannot be modified. In addition, high-volume centers and designated cancer centers have higher readmission rates, which may indicate that readmission rates may not be an appropriate marker for quality improvement.

Background

There is little information on the effects of Pseudomonas infection on outcomes in perforated appendicitis. As Pseudomonas is not covered by many empiric appendicitis antibiotic regiments, we hypothesized that children with Pseudomonas would have worse outcomes.

Methods

Patients <18 years old undergoing appendectomy for perforated appendicitis at a tertiary children's hospital 2015-2019 were included and were stratified by presence of Pseudomonas on intraoperative culture. The primary outcome was post-operative organ-space infection (SSI).

Results

Intraoperative cultures were collected in 58.4% of patients (n = 149/255) with 22.2% (n = 33) positive for Pseudomonas. SSIs occurred in 21.2% of children with Pseudomonas compared to 20.7% of children without Pseudomonas (p = 0.9). Children with Pseudomonas had longer antibiotic duration (9.1 vs. 6.7 days, p = 0.03) and LOS (6.7 vs. 5.9 days, p = 0.03) than those without, but a similar rate of post-operative interventions (12.2% vs. 19.0%, p = 0.4), hospital costs ($28,860 vs. $23,945, p = 0.3), ED visits (9.1% vs. 19.9%, p = 0.3), and readmissions (9.1% vs. 9.5%, p = 1).

Conclusion

Pseudomonas was identified in 22% children with perforated appendicitis and was associated with longer antibiotic durations and LOS, but similar rates of SSI, post-operative interventions, and readmissions compared to children without Pseudomonas. Empiric coverage of Pseudomonas may not be necessary.

Background

Traumatic brain injury (TBI) is the leading cause of death and disability in young children; however, the impact of mechanism on outcomes has not been fully evaluated. We hypothesized that children with TBI due to abuse would have a higher mortality than children with accidental TBI due to motor vehicle collisions (MVC).

Methods

We performed a retrospective review of the National Kids' Inpatient (KID) hospitalizations database of children <2 years old with TBI due to abuse or MVC (2000-2016). The primary outcome was mortality. Secondary outcomes were length of stay (LOS) and hospital charges. We investigated predictors of mortality with multivariable regression.

Results

Of 10,965 children with TBI, 65.2% were due to abuse. Overall mortality was 9.8% (n = 1074). Abused children had longer LOS (5.7 vs 1.6 days, p < 0.0001) and higher hospital charges ($34,314 vs $19,360, p < 0.0001) than children with TBI due to MVC. The odds of mortality were 42% higher in children with abusive head trauma (OR 1.42, 95% CI 1.10-1.83, p = 0.007) compared to MVCs after adjusting for age, race, sex, neurosurgical intervention, injury severity, and insurance.

Conclusion

Children with abusive traumatic brain injury have increased risk of mortality, longer LOS, and higher hospital charges compared to children with TBI due to motor vehicle collision after adjusting for relevant confounders. Resources must be directed at prevention and early identification of abuse.

Background

Drowning is a leading cause of death in children ≤5 years old. Detailed data on the epidemiology of drowning in this high-risk population can inform preventative efforts. We aimed to study trends in incidence and case fatality rates (CFR) in the USA among young children hospitalised after drowning.

Methods

Children ≤5 years old hospitalised in the USA after drowning were identified from the Kids Inpatient Database 2000-2016. Incidence and CFRs by calendar year, age, sex, race/ethnicity and hospital region were calculated. Trends over time were evaluated. Factors associated with fatal drowning were assessed.

Results

Among 30 560 804 hospitalised children ≤5 years old, 9261 drowning cases were included. Patients were more commonly male (62.3%) and white (47.4%). Two years old had the highest incidence of hospitalisation after drowning, regardless of race/ethnicity, sex and region. Overall drowning hospitalisations decreased by 49% from 2000 to 2016 (8.38-4.25 cases per 100 000 children). The mortality rate was 11.4% (n=1060), and most occurred in children ≤3 years old (83.0%). Overall case fatality decreased between 2000 and 2016 (risk ratio (RR) 0.44, 95% CI 0.25 to 0.56). The lowest reduction in incidence and case fatality was observed among Black children (Incidence RR 0.92, 95% CI 0.75 to 1.13; case fatality RR 0.80, 95% CI 0.41 to 1.58).

Conclusions

Hospitalisations and CFRs for drowning among children ≤5 years old have decreased from 2000 to 2016. Two years old are at the highest risk of both fatal and non-fatal drowning. Disparities exist for Black children in both the relative reduction in drowning hospitalisation incidence and case fatality. Interventions should focus on providing equitable preventative care measures to this population.

Introduction

Optimal management of pediatric perforated appendicitis remains a topic of active investigation. Our institutional clinical practice guidelines (CPGs) were modified to discontinue antibiotics on discharge for patients with normal white blood cell count (WBC) without left shift. We hypothesized that patients would receive fewer antibiotics without increased complications.

Methods

Patients <18 y old with perforated appendicitis who underwent laparoscopic appendectomy between November 1, 2016 and May 31, 2021 at a tertiary care children's hospital were included. Primary outcome was adverse events: postdischarge surgical site infection (SSI), 30-day emergency department (ED) visits, or readmissions. Outcomes were compared before and after CPG modification. Multivariable regression was performed to identify factors associated with SSI.

Results

There were 113 patients pre- and 97 patients post-CPG modification. 23.1% of patients in the pre-cohort had an elevated discharge WBC or left shift compared to 18.9% of patients in the post-cohort (P = 0.48). Significantly fewer patients were prescribed antibiotics on discharge in the post-cohort (70.8% pre versus 14.4% post, P < 0.0001) and for fewer days (2 pre versus 0 post, P < 0.0001). Total antibiotic days decreased significantly (6.1 pre versus 4.6 post, P < 0.0001). There was an increase in postdischarge SSIs on univariate analysis (1.8% pre versus 9.3% post, P = 0.03), ED visits (9.7% pre versus 19.6% post, P = 0.04), and readmissions (5.3% pre versus 11.3% post, P = 0.13). On multivariable analysis, being in the post-cohort was not significantly associated with post-discharge SSIs after adjusting for sex, symptom duration, initial WBC, and discharge antibiotic duration (OR 0.25, 95% CI 0.04-1.4, P = 0.11).

Conclusions

Modification of a pediatric perforated appendicitis clinical practice guideline to discontinue antibiotics on discharge with a normal WBC without left shift was effective in decreasing antibiotic duration. This was associated with an increase in SSIs on univariate analysis, which did not persist on multivariable analysis and requires further investigation.

Diagnosis of a tumor in utero is a rare occurrence and poses diagnostic and therapeutic challenges. In cases of tumor-associated hydrops, there is significant risk of fetal demise, and prenatal intervention may be considered to avoid this outcome when possible. When fetal intervention is unlikely to improve survival, information can be useful for counseling families. We present a rare case of fetal diagnosis of a primary renal malignancy with widespread metastases and hydrops, with unique immunohistochemical findings consistent with malignant primitive epithelioid sarcoma with features of rhabdoid tumor.

Introduction

The COVID-19 pandemic has widespread effects, including enhanced psychosocial stressors and stay-at-home orders which may be associated with higher rates of child abuse. We aimed to evaluate rates of child abuse, neglect, and inadequate supervision during the COVID-19 pandemic.

Methods

Patients ≤5 y old admitted to a level one pediatric trauma center between 3/19/20-9/19/20 (COVID-era) were compared to a pre-COVID cohort (3/19/19-9/19/19). The primary outcome was the rate of child abuse, neglect, or inadequate supervision, determined by Child Protection Team and Social Work consultations. Secondary outcomes included injury severity score (ISS), mortality, and discharge disposition.

Results

Of 163 total COVID-era pediatric trauma patients, 22 (13.5%) sustained child abuse/neglect, compared to 17 of 206 (8.3%) pre-COVID era patients (P = 0.13). The ISS was similar between cohorts (median 9 pre-COVID versus 5 COVID-era, P = 0.23). There was one mortality in the pre-COVID era and none during COVID (P = 0.45). The rate of discharge with someone other than the primary caregiver at time of injury was significantly higher pre-COVID (94.1% versus 59.1%, P = 0.02). In addition, foster family placement rate was twice as high pre-COVID (50.0% versus 22.7%, P = 0.10).

Conclusions

The rate of abuse/neglect among young pediatric trauma patients during COVID did not differ compared to pre-pandemic, but discharge to a new caregiver was significantly lower. While likely multifactorial, this data suggests that resources during COVID may have been limited and the clinical significance of this is concerning. Larger studies are warranted to further evaluate COVID-19's effect on this vulnerable population.

Background

Despite advances in prenatal repair, myelomeningocele (MMC) still produces devastating neurologic deficits. The amniotic membranes (AM) are a biologically active tissue that has been used anecdotally for human fetal MMC repair. This study evaluated the use of autologous AM compared to skin closure in an established fetal MMC model.

Methods

Seven fetal lambs underwent surgical creation of MMC at gestational age of 75days followed by in utero repair at gestational age of 100days. Lambs were repaired with an autologous AM patch followed by skin closure (n=4) or skin closure alone (n=3). Gross necropsy and histopathology of the spinal cords were performed at term to assess neuronal preservation at the lesion.

Results

An increase in preserved motor neurons and a larger area of spinal cord tissue were seen in AM-repaired lambs, as was decreased wound healing of the overlying skin. Loss of nearly all spinal cord tissue with limited motor neuron preservation was seen in skin only-repaired lambs.

Conclusions

AM-repaired lambs showed increased protection of spinal cord tissue compared to skin only-repaired lambs, but the overlying skin failed to close in AM-repaired lambs. These results suggest a potential role for AM in fetal MMC repair that warrants further study.

The differential for neonatal hematoma sis ranges from benign etiologies to life-threatening emergencies. Neonatal gastric perforation is a rare cause of neonatal hematoma sis but is a deadly condition, requiring prompt diagnosis and treatment. The etiology is usually related to conditions predisposing to over distension of the stomach, such as positive pressure ventilation or distal obstruction, but in some cases cannot be determined. Patients generally present with abdominal distension and respiratory distress. We present a case of a 1-day old term baby girl who developed sudden onset hematoma sis and clinical deterioration, who was found to have a large proximal gastric perforation requiring emergent total gastrectomy with delayed reconstruction.

Introduction

Fetal amniotic membranes (FM) have been shown to preserve spinal cord histology in the fetal sheep model of myelomeningocele (MMC). This study compares the effectiveness of placenta-derived mesenchymal stromal cells (PMSCs) from early-gestation versus term-gestation placenta to augment FM repair to improve distal motor function in a sheep model.

Methods

Fetal lambs (n = 4) underwent surgical MMC creation followed by repair with FM patch with term-gestation PMSCs (n = 1), FM with early-gestation PMSCs (n = 1), FM only (n = 1), and skin closure only (n = 1). Histopathology and motor assessment was performed.

Results

Histopathologic analysis demonstrated increased preservation of spinal cord architecture and large neurons in the lamb repaired with early-gestation cells compared to all others. Lambs repaired with skin closure only, FM alone, and term-gestation PMSCs exhibited extremely limited distal motor function; the lamb repaired with early-gestation PMSCs was capable of normal ambulation.

Discussion

This pilot study is the first in vivo comparison of different gestational-age placenta-derived stromal cells for repair in the fetal sheep MMC model. The preservation of large neurons and markedly improved motor function in the lamb repaired with early-gestation cells suggest that early-gestation placental stromal cells may exhibit unique properties that augment in utero MMC repair to improve paralysis.
