Variation in pediatric surgical care

Improving quality and efficiency of care for advanced appendicitis in children

BACKGROUND

Complicated appendicitis encompasses a spectrum of severity with heterogeneity in definition and substantial variation in care. Enhanced recovery after surgery or 'fast-track' protocols aim to reduce practice variation by standardizing care. These initiatives may improve quality and efficiency of care, preserve resources and expedite discharge. This study aims to evaluate the impact of a standardized Enhanced Recovery Pathway (ERP) on the post-operative recovery of children with a subset of complicated appendicitis termed 'advanced' appendicitis.

METHODS

We defined advanced appendicitis as gangrenous or suppurative appendicitis without perforation, contained iatrogenic perforation, or localized purulent fluid. Children with operative findings reflecting these criteria were enrolled in the ERP protocol. Key protocol components include early upgrade of diet, avoidance of intravenous analgesia, abridged intravenous antibiotics, early ambulation and standardized discharge criteria. The study period was May 2018 to June 2019. A historical cohort was used as the comparator group.

RESULTS

Outcomes for 44 children treated under the ERP were compared to 44 historical controls. There was a 20% reduction in median post-operative length of stay (1.80 vs. 2.24 days, p = 0.02). Intravenous analgesia was received by fewer patients (6.8% vs. 36.4%, p = 0.01) with significant reduction in antiemetic requirement (p = 0.03). No significant difference in 30-day complication rates was observed.

CONCLUSION

Reduced post-operative length of stay and reduction in practice variation were achieved after implementation of a 'fast-track' protocol for children with advanced appendicitis. Additional benefits of this protocol include reduced provision of intravenous morphine analgesia, decreased resource use and cost savings.

Fast-track surgery for uncomplicated appendicitis in children: a matched case-control study

BACKGROUND

Standardized post-operative protocols reduce variation and enhance efficiency in patient care. Patients may benefit from these initiatives by improved quality of care. This matched case-control study investigates the effect of a multidisciplinary criteria-led discharge protocol for uncomplicated appendicitis in children.

METHODS

Key protocol components included limiting post-operative antibiotics to two intravenous doses, avoidance of intravenous opioid analgesia, prompt resumption of diet, active encouragement of early ambulation and nursing staff autonomy to discharge patients that met assigned criteria. The study period was from August 2015 to February 2016. Outcomes were compared with a historical control group matched for operative approach.

RESULTS

Outcomes for 83 patients enrolled to our protocol were compared with those of 83 controls. There was a 29.2% reduction in median post-operative length of stay in our protocol-based care group (19.6 versus 27.7 h; P < 0.001). The rate of discharges within 24 h improved from 12 to 42%. There was no significant difference in complication rate (4.8 versus 7.2%; P = 0.51). Mean oral morphine dose equivalent per kilogram requirement was less than half (46%) that of control group patients (P < 0.001). Mean number of ondansetron doses was also significantly lower. Projected annual direct cost savings following protocol implementation was AUD$77 057.

CONCLUSION

Implementation of a criteria-led discharge protocol at our hospital decreased length of stay, reduced variation in care, preserved existing low morbidity, incurred substantial cost savings, and safely rationalized opioid and antiemetic medication. These protocols are inexpensive and offer tangible benefits that are accessible to all health care settings.

Paradigm Shifts in the Treatment of Appendicitis

Acute appendicitis is the most common cause of emergent surgery in children. Historically, surgical dogma dictated emergent appendectomy due to concern for impending perforation. Recently, however, there has been a paradigm shift in both the understanding of its pathophysiology as well as its treatment to more nonoperative management. No longer is it considered a spectrum from uncomplicated appendicitis inevitably progressing to complicated appendicitis over time. Rather, uncomplicated and complicated appendicitis are now considered two distinct pathophysiologic entities. This change requires not only educating the patients and their families but also the general practitioners who will be managing treatment expectations and caring for patients long term. In this article, we review the pathophysiology of appendicitis, including the differentiation between uncomplicated and complicated appendicitis, as well as the new treatment paradigms.
