Evaluation of Pediatric Readiness Using Simulation in General Emergency Departments in a Medically Underserved Region

BACKGROUND

Regionalization of pediatric care in the United States was developed to improve care by directing patients to hospitals with optimal pediatric resources and experience, leading to less pediatric-trained providers in medically underserved areas. Children with emergencies, however, continue to present to local general emergency departments (GEDs), where pediatric emergencies are low-frequency, high-risk events.

OBJECTIVE

The goals of this project were to: increase exposure of GEDs in the southeast United States to pediatric emergencies through simulation, assess pediatric emergency clinical care processes with simulation, describe factors associated with readiness including volume of pediatric patients and ED location (urban/rural), and compare these findings to the 2013 National Pediatric Readiness Project.

METHODS

This prospective in situ simulation study evaluated GED readiness using the Emergency Medical Services for Children Pediatric Readiness Score (PRS) and team performance in caring for 4 simulated pediatric emergencies. Comparisons between GED and pediatric ED (PED) performance and PRS, GED performance, and PRS based on pediatric patient volume and hospital location were evaluated. A Composite Quality Score (CQS) was calculated for each ED.

RESULTS

Seventy-five teams from 40 EDs participated (39 GED; 1 PED). The PED had a significantly higher volume of pediatric patients (73,000 vs 4492; P = 0.003). The PRS for GEDs was significantly lower (57% [SD, 17] vs 98%; P = 0.022). The CQSs for all GEDs were significantly lower than the PED (55% vs 87%; P < 0.004). Among GEDs, there was no statistically significant difference in PRS or CQS based on pediatric patient volume, but urban GEDs had significantly higher CQSs versus rural GEDs (59.8% vs 50.6%, P = 0.001).

CONCLUSIONS

This study shows a significant disparity in the performance and readiness of GEDs versus a PED in a medically underserved area. More education and better access to resources is needed in these areas to adequately care for critically ill pediatric patients.

The Impact of a Multifaceted Simulation Education and Feedback Program for Community Emergency Departments on Pediatric Diabetic Ketoacidosis Management

OBJECTIVES

We sought to determine if general emergency departments (GEDs) were managing pediatric diabetic ketoacidosis (DKA) correctly and if management could be improved using a multilayered educational initiative. We hypothesized that a multifaceted program of in situ simulation education and formal feedback on actual patient management would improve community GED management of pediatric DKA.

METHODS

This study combined a prospective simulation-based performance evaluation and a retrospective chart review. A community outreach simulation education initiative was developed followed by a formal patient feedback process.

RESULTS

Fifteen hospitals participated in simulation sessions and the feedback process. All hospitals were scored for readiness to provide care for critically ill pediatric patients using the Emergency Medical Services for Children (EMSC) Pediatric Readiness Assessment. Six of the 15 have had a second hospital visit that included a DKA scenario with an average performance score of 60.3%. A total of 158 pediatric patients with DKA were included in the chart review. The GEDs with higher patient volumes provided best practice DKA management more often (63%) than those with lower patient volumes (40%). Participating in a DKA simulated scenario showed a trend toward improved care, with 47.2% before participation and 68.2% after participation ( P = 0.091). Participating in the formal feedback process improved best practice management provided to 68.6%. Best practice management was further improved to 70.3% if the GED participated in both a DKA simulation and the feedback process ( P = 0.04).

CONCLUSIONS

A multifaceted program of in situ simulation education and formal feedback on patient management can improve community GED management of pediatric patients with DKA.

A ten-year study of Retinoblastoma in Uganda: An approach to improving outcome with limited resources

BACKGROUND

Survival of children with cancer in resource-limited regions is very poor compared to better-resourced regions. Retinoblastoma (RB) is a childhood cancer that is commonly reported in many regions of Africa. RB may be safely and effectively treated by non-specialists, which could facilitate more widespread availability of treatment in under-resourced areas.

METHODS

A ten-year consecutive series of children with RB treated at Ruharo Eye Centre between December 2009 and November 2019 was prospectively followed up. Chemoreduction followed by surgery is the standard approach to therapy. Costs of therapy and also of travel and food are borne by the program which is unaffordable to most families and necessitates donors. Survival by stage of RB and number of eyes affected was described using Kaplan-Meier plots. Visual acuity was assessed for all children with bilateral disease and the retention of sight during follow-up assessed.

RESULTS

Among 665 children with RB, 18.2 % (121 children) presented with metastatic (Stage 4) RB with only two of these children surviving >24 months. Five-year survival was 60.2 % among all children with RB rising to 93.3 % and 87.2 % for children with unilateral and bilateral Stage 1 disease, respectively. Among 184 children with bilateral disease, 130 (70.7 %) retained some level of sight following primary treatment with 91 of those (49.5 % of all bilateral children) retaining vision up to their death or to the end of follow-up.

CONCLUSION

Many children in Uganda present with advanced RB and curative treatment is not possible in this setting. Children diagnosed and treated early have good prospects of survival. Retention of sight among many bilaterally affected children is achievable, facilitating access to normal education. Therefore, the strategic priorities for improving survival are changing community perceptions so that children with eye problems are brought without delay, and widening access to modern treatment by using genereal health workers with standard drugs, backed by financial, social and peer support.

Parameters influencing the efficiency of the thymidine kinase/ganciclovir strategy in human glioblastoma cell lines

The gene therapy strategy using the hsv1-thymidine kinase gene (TK) and ganciclovir (GCV) injections that has been used for treating human glioblastomas has not been as effective as expected after the first animal experiments. A better understanding of the different steps involved in this treatment, like gene transfer, gene expression, and sensitivity of the recipient cells is needed. Therefore, we studied 7 human glioblastoma cell lines (U87, U118, U251, SNB19, SNB75, SF295, SF539) for their sensitivity to the TK/GCV system. We also studied their in vitro bystander effect and their in vitro transfectability using LipofectAMINE as a transfection enhancer. According to this in vitro analysis, most of the glioblastoma cell lines should be sensitive to the TK/GCV system, but there is a significant need for agents to increase transfection efficiency.

Variable efficiency of the thymidine kinase/ganciclovir system in human glioblastoma cell lines: implications for gene therapy

The gene therapy strategy using the hsvl-thymidine kinase gene (TK) and ganciclovir (GCV) injections that has been used for treating human glioblastomas has not been as effective as expected after the first animal experiments. A better understanding of the different steps involved in this treatment, like gene transfer, gene expression, and sensitivity of the recipient cells, is needed. After proposing sensitivity criteria for the TK/GCV system and for the bystander effect, based on the levels of GCV that can be reached in vivo, we studied seven human glioblastoma cell lines (U87, U118, U251, SNB19, SNB75, SF295, SF539) for their sensitivity to the TK/GCV system. We also studied their in vitro bystander effect and their in vitro transfectability using LipofectAMINE as a transfection enhancer. Among six human glioblastoma cell lines stably transfected with the TK gene, five were sensitive to TK/GCV, and two had a good in vitro bystander effect. The in vitro transfectability of the cell lines tested was low (< or = 1%) compared to that of an established animal cell line, C6 rat glioma, in which 20-30% of the cells can be transfected routinely. According to this in vitro analysis, most of the glioblastoma cell lines should be sensitive to the TK/GCV system, but there is an urgent need for agents to increase transfection efficiency.

Dietary fat promotes mammary tumorigenesis in MMTV/v-Ha-ras transgenic mice

The purpose of this study was to investigate the influence of dietary fat on mammary tumorigenesis in MMTV/v-Ha-ras transgenic mice. Female MMTV/v-Ha-ras transgenics were fed diets providing 0, 5 or 25% of calories from corn oil (CO). The mammary tumor incidence was 7% (0% CO), 36% (5% CO) and 52% (25% CO). Ras mRNA levels were increased in mammary tumors in the 25% CO group. The ras transgene was hypomethylated in mammary tumors, but not in liver or nontransformed mammary tissue. Mammary tumors expressed apolipoprotein E mRNA. Alterations in gene structure and expression in transgenic mice may suggest mechanisms by which dietary fat promotes mammary tumors.
