Methods

• use national benchmarks

• pre- and post-implementation of the

multidisciplinary care pathway

– plan-do-study-act (PDSA) cycles

• track and examine metrics:

– clinical database

– medical records

– cross-referencing with national database [Pediatric

Health Information System (PHIS)]

Data driven approach

xxx00.#####.ppt 8/10/2019 9:28:50 AM

Multidisciplinary care pathway

driven by best practice guidelines/consensus/other:

• streamline preoperative workup

• improve perioperative communication

• reduce variation in care

xxx00.#####.ppt 8/10/2019 9:28:50 AM

Change is not always welcomed.

How to motivate for change?

• People want to do the

right thing for patients

Make it easy to do the

right thing: build paths

of least resistance

• Reduce uncertainty &

build trust

OBJECTIVE In children, the repair of skull defects arising from decompressive craniectomy presents a unique set of challenges. Single-center studies have identified different risk factors for the common complications of cranioplasty resorption and infection. The goal of the present study was to determine the risk factors for bone resorption and infection after pediatric cranioplasty.

METHODS The authors conducted a multicenter retrospective case study that included all patients who underwent cra-nioplasty to correct a skull defect arising from a decompressive craniectomy at 13 centers between 2000 and 2011 and were less than 19 years old at the time of cranioplasty. Prior systematic review of the literature along with expert opinion guided the selection of variables to be collected. These included: indication for craniectomy; history of abusive head trauma; method of bone storage; method of bone fixation; use of drains; size of bone graft; presence of other implants, including ventriculoperitoneal (VP) shunt; presence of fluid collections; age at craniectomy; and time between craniecto-my and cranioplasty.

RESULTS A total of 359 patients met the inclusion criteria. The patients’ mean age was 8.4 years, and 51.5% were female. Thirty-eight cases (10.5%) were complicated by infection. In multivariate analysis, presence of a cranial implant (primarily VP shunt) (OR 2.41, 95% CI 1.17–4.98), presence of gastrostomy (OR 2.44, 95% CI 1.03–5.79), and ventilator dependence (OR 8.45, 95% CI 1.10–65.08) were significant risk factors for cranioplasty infection. No other variable was associated with infection.

Of the 240 patients who underwent a cranioplasty with bone graft, 21.7% showed bone resorption significant enough to warrant repeat surgical intervention. The most important predictor of cranioplasty bone resorption was age at the time of cranioplasty. For every month of increased age the risk of bone flap resorption decreased by 1% (OR 0.99, 95% CI 0.98–0.99, p < 0.001). Other risk factors for resorption in multivariate models were the use of external ventricular drains and lumbar shunts.
