Abstract

Objectives

Tertiary hospitals see a wide array of complex paediatric patients requiring the procedure of tonsillectomy to alleviate airway symptoms. To investigate the implications of patient-specific factors on postoperative morbidities and hospital stay length, including the role of BMI and AH as predictors for airway complications following surgery.

Methods

A retrospective chart review was performed for all patients presenting at The Children's Hospital at Westmead for routine tonsillectomy between July 2010 and July 2014.

Results

Of 500 charts, 420 patients met inclusion criteria. 155 (37%) patients had a pre-existing comorbidity. Polysomnogram (PSG) was conducted prior to surgery (n=129). BMI results showed a mean BMI of 20.0, n=25 were overweight, n=70 were obese and n=11 underweight. 84 patients (20%) experienced a postoperative complication/unexpected morbidity. There were no returns to theatre and no mortality. 24 patients had more than one complication. Complication rate was highest in the patients <2 years of age. There was a statistically significant difference in the number of desaturation related complications between obese and non-obese groups p=0.00480. There was statistically significant difference in length of hospital stay between the two groups. 16% of children with co-morbidities stayed for >2 nights in hospital (25/155) compared to 7.5% of children without co-morbidities p=0.00607. 9% of children with co-morbidities stayed for 3 nights in hospital (14/155) compared to patients without co-morbidities (6/256), p= 0.00167.

Conclusions

This audit confirms the impact of age, obesity and certain co-morbidities on the potential costs to the hospital in managing complications and length of stay after surgery.
