Pediatric Preoperative Assessment: Six Million Missed Opportunities for Childhood Obesity Education

Pediatric obesity and perioperative medicine

PURPOSE OF REVIEW

Childhood obesity is a public health emergency that has reached a pandemic level and imposed a massive economic burden on healthcare systems. Our objective was to provide an update on (1) challenges of obesity definition and classification in the perioperative setting, (2) challenges of perioperative patient positioning and vascular access, (3) perioperative implications of childhood obesity, (3) anesthetic medication dosing and opioid-sparing techniques in obese children, and (4) research gaps in perioperative childhood obesity research including a call to action.

RECENT FINDINGS

Despite the near axiomatic observation that obesity is a pervasive clinical problem with considerable impact on perioperative health, there have only been a handful of research into the many ramifications of childhood obesity in the perioperative setting. A nuanced understanding of the surgical and anesthetic risks associated with obesity is essential to inform patients' perioperative consultation and their parents' counseling, improve preoperative risk mitigation, and improve patients' rescue process when complications occur.

SUMMARY

Anesthesiologists and surgeons will continue to be confronted with an unprecedented number of obese or overweight children with a high risk of perioperative complications.

The impact of abnormal BMI on surgical complications after pediatric colorectal surgery

BACKGROUND/PURPOSE

While childhood obesity is a growing problem, the implications of BMI on elective pediatric surgery remains poorly described. This study evaluates the impact of obesity on surgical outcomes after elective colorectal procedures.

METHODS

Children ages 2-18 years undergoing elective colorectal surgery for IBD were identified from the NSQIP-Pediatric database. Patients were classified as underweight (UW), normal weight (NW), overweight (OW) and obese (OB) based on their age- and sex-adjusted BMI. Postoperative complications were compared between cohorts.

RESULTS

858 patients (14.8% UW, 64.3% NW, 13.1% OW, 7.8% OB) were identified, with overall complications occurring in 15.3% and SSI in 10.1%. Obese/overweight patients had higher rates of deep incisional SSI (4.5%OB, 4.5%OW, 0%NW, p=0.002) and superficial wound disruption (5.4%OB, 5.8%OW, 1.6%NW, p=0.04). Incremental increase in BMI by 1.0kg/m² was associated with 4.3% increased likelihood of developing deep incisional SSI and 2.3% increase of superficial wound disruption. Obese/overweight children also had increased incidence of septic shock and UTI, as well as longer operative times, days of mechanical ventilation and LOS.

CONCLUSIONS

Increasing BMI was associated with increased wound complications in IBD patients undergoing elective intestinal surgery. Preoperative optimization and weight loss strategies may potentially reduce SSI and other infectious complications.

A pilot study on secondhand tobacco exposure: parental knowledge about health impact and feasibility of cessation

Introduction

As the primary source of smoke exposure is in the home, the smoking behaviors of parents and other caregivers are key determinants of a child's exposure to secondhand smoke. The perioperative period offers an opportunity to discuss smoking cessation strategies.

Methods

This prospective study included 97 parents or caregivers of patients undergoing dental surgery. Caregivers were surveyed in the dental waiting room during the preoperative phase. The primary aim was to determine the feasibility of using the preoperative encounter to offer smoking cessation resources to parents of pediatric patients. The secondary aim was to compare willingness to receive smoking cessation resources according to the knowledge of the risks of secondhand smoking (ie, being aware of secondhand smoking and knowing that it posed a risk to their child).

Results

Awareness of risks due to secondhand smoking was 65% in the overall cohort and 58% among current smokers (P=0.284 vs nonsmokers). Among smokers in our study, only a small percentage (12%) were interested in smoking cessation help. Knowledge of the risks of secondhand smoke may not be sufficient for smokers to express willingness to receive help.

Conclusion

The outpatient clinic may be a teaching opportunity for smoking cessation for caregivers. However, we found that only a small percentage of caregivers were interested in receiving information about smoking cessation. This was despite the fact they were aware of the potential adverse effects of secondhand smoke on their children.

The difficult conversation: a qualitative evaluation of the 'Eat Well Move More' family weight management service

OBJECTIVE

The Eat Well Move More (EWMM) family and child weight management service is a 12-week intervention integrating healthy eating and physical activity education and activities for families and children aged 4-16. EWMM service providers identified low uptake 12 months prior to the evaluation. The aims of this study were to describe referral practices and pathways into the service to identify potential reasons for low referral and uptake rates.

RESULTS

We conducted interviews and focus groups with general practitioners (GPs) (n = 4), school nurses, and nursing assistants (n = 12). Data were analysed using thematic analysis. School nurses highlighted three main barriers to making a referral: parent engagement, child autonomy, and concerns over the National Child Measurement Programme letter. GPs highlighted that addressing obesity among children is a 'difficult conversation' with several complex issues related to and sustaining that difficulty. In conclusion, referral into weight management services in the community may persistently lag if a larger and more complex tangle of barriers lie at the point of school nurse and GP decision-making. The national prevalence of, and factors associated with this hesitation to discuss weight management issues with parents and children remains largely unknown.
