Development and Evaluation of the Pediatric Readiness for Discharge (P-REDI) Tool.

PURPOSE: The purpose of this study was to evaluate the P-REDI discharge tool for safe discharge to home following ambulatory surgery. DESIGN: A quasi-experimental, mixed methods with pre/post nurse surveys and retrospective chart review comparing pre-, interim- and post-implementation of P-REDI on unscheduled clinic visits, Emergency Department visits, hospital readmission, and length of stay. METHODS: The P-REDI tool was developed in collaboration with anesthesia and based upon an extensive review of the literature on safe discharge from the Phase II Postanesthesia Care Unit (PACU). Nurse surveys and patient data extracted from the electronic health record through the computer-assisted reporting system were analyzed using descriptive statistics, bivariate statistics, and correlations to assess outcomes and relationships between variables. FINDINGS: Nurses' perceptions of discharge criteria improved after implementation of P-REDI. There were no differences in adverse events before, during, and after the implementation of the P-REDI instrument. There was a significant decrease in Phase II time after implementation of the tool. There were also significant correlations with the P-REDI score and related variables such as length of surgical procedure time and length of stay. CONCLUSIONS: The P-REDI tool was developed to provide nurses a concrete, objective tool to increase their level of comfort with discharging patients from the Phase II PACU. The tool significantly decreased length of stay in Phase II without any change in adverse events. The cost savings to the institution needs to be examined in future studies.

The relationship between obesity and sleep timing behavior, television exposure, and dinnertime among elementary school-age children.

STUDY OBJECTIVES: The daily lifestyle behaviors of children have been shown to be associated with obesity. There are limited studies on the association of sleep timing behavior and body mass index (BMI), specifically in elementary school-age children. This study aimed to investigate the relationship between obesity and sleep timing patterns, television exposure time, and dinnertime among elementary school-age children. METHODS: Children (n = 169) aged 6 to 10 years who were residents of Alabama were recruited for this study. The questionnaires were used to determine the bedtime, wake-up time, television exposure time, and dinnertime of the participants. The participants were categorized into four groups depending on the bedtime and wake-up time behavior habits: early bed/early wake-up (EE); early bed/late wake-up (EL); late bed/early wake-up (LE); and late bed/late wake-up (LL) time. The BMI z-score, television exposure time, and dinnertime of these groups were compared. RESULTS: The LL group had a significantly higher BMI z-score compared to the EE group. The higher BMI z-score in the LL group may be associated with late bedtime and not late wake-up time. Approximately 71% of children with late bedtime (8:48 pm), 75% of children who watch television for more than 1 hour, and 54% of children who have dinner after 7:00 pm have obesity. CONCLUSIONS: Daily behavior habits such as late bedtime, increased television exposure, and late dinnertime are associated with obesity.

Association of Salivary Amylase (AMY1) Gene Copy Number with Obesity in Alabama Elementary School Children.

Salivary amylase (AMY1) is the most abundant enzyme in human saliva, responsible for the hydrolysis of α-1,4 glycosidic linkages that aids in the digestion of starch. Recently studies have shown that the copy number of AMY1 is associated with obesity; however, the data varies with location. One-third of children are overweight/obese in Alabama. In this study, we aim to determine the relationship between the copy number of AMY1 gene and obesity measurements in children from Alabama. One hundred twenty-seven children aged between 6 to 10 years participated in this study. Anthropometric measurements were measured using WHO recommendations. Genomic DNA was extracted from saliva, and the copy number of the AMY1 gene was estimated by digital PCR. The association between AMY1 copy number and obesity measurements was analyzed by linear regression. The mean AMY1 copy number significantly decreased in overweight/obese (6.21 ± 1.48) compared to normal weight (7.97 ± 2.35) children. AMY1 copy number inversely associated with the obesity measurements. African Americans had a stronger association between low AMY1 copy number and obesity compared to white/European Americans. Our findings suggest that overweight/obese children have a low AMY1 copy number and the effect is more prominent in African Americans.
