Effectiveness and Safety of Independent Pediatric Nurse Practitioners in Evaluating Plagiocephaly:

Advanced Practice Providers in Pediatric Surgery: A 10-Year Analysis of Clinical Productivity

BACKGROUND

Advanced practice providers (APPs) are integral to nonsurgical and surgical fields. In surgical settings, APPs work autonomously alongside surgeons to enhance continuity of care. Although small-scale studies across various surgical specialties have explored APP use, literature specific to the pediatric population is limited. This study assesses the impact of increased APP use on productivity within one of the largest pediatric surgery departments in the United States.

METHODS

Data were sourced from the Surgery Department Executive Committee annual reports. Descriptive analyses were performed to delineate trends in clinical volumes, operating room (OR) cases, gross charges, work relative value units, and provider full-time equivalents between October of 2011 and September of 2023. Secondary analyses were performed from 2016 to 2023, after APP roles were refined in each division.

RESULTS

Since 2012, an upward trend is observed in total clinic visits, total OR cases, and OR cases per physician (MD). In 2016, APPs saw 1 clinic patient for every 2.2 seen by MDs, decreasing to a 1:1 ratio by 2023. The MD surgical conversion rate has increased by 20.5% since 2016, and the conversion rate per total clinic volume has decreased by 7.3% over the same period. Total work relative value units and gross charges increased across the department and per provider, despite fewer overall providers since 2021.

CONCLUSIONS

Increased use of APPs within the department of surgery may enhance procedural productivity for surgeons while ensuring continued patient access to care. This study highlights the importance of developing care models that optimize the full skillset of APPs.

Safety and efficacy of independent allied healthcare professionals in the assessment and management of plagiocephaly patients

BACKGROUND

The incidence of positional plagiocephaly has increased significantly over the last two decades, which has caused a service delivery challenge for pediatric neurosurgeons. As a potential solution to the long waitlists for abnormal head shape, a plagiocephaly clinic was established at BC Children's Hospital (BCCH) in Vancouver, Canada. This clinic was supervised by an occupational therapist who had been trained by a neurosurgeon to independently assess and manage patients with a referring diagnosis of positional plagiocephaly.

OBJECTIVES

To determine the efficiency of the BCCH Plagiocephaly Clinic in the management of positional plagiocephaly patients and to investigate the clinic's ability to appropriately identify and refer patients with craniosynostosis to pediatric neurosurgeons for further assessment.

METHODS

A retrospective chart review was conducted to identify patients who were assessed and managed at the BCCH Plagiocephaly Clinic between 2008 and 2014. Data on patient demographics, head shape measurements, and treatment recommendations were collected, and the BC Children's neurosurgical database was cross-referenced to identify craniosynostosis cases missed by the Plagiocephaly Clinic. A descriptive analysis of the clinic's average wait times, severity of the patients' plagiocephaly, and recommended interventions was conducted. In addition, the sensitivity and specificity of the clinic's ability to appropriately refer craniosynostosis patients to pediatric neurosurgery were calculated.

RESULTS

Of 1752 patients seen in the BC Children's Plagiocephaly Clinic between 2008 and 2014, 66% of patients received counseling about repositioning, 34% were referred for head banding, 19% were referred to physiotherapy for torticollis, and 1.4% were referred to the BC Children's Pediatric Neurosurgery Clinic for suspicion of craniosynostosis. The mean time from referral to first assessment by the Plagiocephaly Clinic was 41 days, and time from referral by the plagiocephaly clinic to diagnosis of craniosynostosis by a pediatric neurosurgeon was 8 days. Pediatric neurosurgeons requested imaging for 6 of the referred patients (25% ). The sensitivity and specificity of the plagiocephaly clinic for referral of craniosynostosis patients to the Pediatric Neurosurgery Clinic were 100 and 99%, respectively.

CONCLUSION

The BC Children's Plagiocephaly Clinic is efficient and safe for the initial evaluation and treatment of patients with positional plagiocephaly. The clinic's model decreases wait times, appropriately manages patients with positional plagiocephaly, screens for craniosynostosis with high sensitivity and specificity, and takes pressure off outpatient neurosurgical clinics. This model for assessment of plagiocephaly could be considered in other medical centers.

Impact of an advanced practice provider-directed plagiocephaly clinic for neurosurgical practices

OBJECTIVE

In recent years, the Weill Cornell neurosurgical team noticed an increase in referrals for plagiocephaly, likely due to increased infant back-sleeping and awareness. A plagiocephaly clinic staffed by a nurse practitioner and a physician assistant was established in 2016 to meet this demand, and to decrease the nonsurgical case burden on neurosurgeons. The purpose of this study was to examine the impact of a clinic directed by advanced nonphysician practice providers (NPPs) on parental satisfaction and nonsurgical work hours for staff neurosurgeons.

METHODS

Over a 1.5-year period (from January 1, 2016, to June 20, 2017), Likert scale-based surveys were administered to parents before and after their child's visit to the NPP-staffed clinic. Clinic hours were tracked to assess impact on the neurosurgeon's workload.

RESULTS

All 185 patients seen in the plagiocephaly clinic over the 1.5-year period completed pre- and postvisit surveys. Parents all reported a significant reduction in their level of concern for their child's diagnosis after the evaluation, and 95.5% were "very likely" to recommend the clinic. All parents felt that there was an increase in their knowledge base after an appointment with an NPP. Additionally, over 1 year in the study, 170 visits to the NPP plagiocephaly clinic were recorded, resulting in 85 hours that neurosurgeons normally would have spent in the clinic that they now were able to spend in the operating room.

CONCLUSIONS

This research provides evidence that an NPP-directed clinic can positively impact parental satisfaction and decrease nonsurgical case burden on neurosurgeons.

Reliable Assessors of Infant Cranial Asymmetry in Child Health Care

INTRODUCTION

Acquired cranial asymmetry is prevalent in infants today and largely attributed to the supine sleep position recommended for infant safety. There is a risk of permanent cranial asymmetry, so prevention and early detection are important. A prevention project was initiated in Sweden, and an intervention was planned. The aim of this study was to evaluate reliability of assessors judging infant cranial asymmetry in order to evaluate if they could be considered reliable interchangeable assessors in the planned intervention.

MATERIALS AND METHODOLOGY

Five assessors were taught how to assess infant cranial asymmetry using illustrated severity assessments. They were intra-rater and inter-rater reliability tested by taking a photograph test-retest and an infant test. Agreement matrices were devised to illustrate assessor agreement based on both type and degree of cranial asymmetry. Agreement based on degree of asymmetry was analyzed by calculating AC2 using quadratic weights. Results were adjusted to arrive at the perceived genuine agreement and interpreted according to Landis and Koch's strength of agreement intervals.

RESULTS

In the photograph test, mean percentage of perfect intra-rater agreement was 73. Adjusted mean intra-rater AC2 was 0.69 [0.63; 0.76], and adjusted inter-rater AC2s were 0.72 [0.64; 0.81] and 0.71 [0.63; 0.79]. In the infant test, the adjusted inter-rater AC2 was 0.73 [0.60; 0.87]. Results indicate substantial strength of assessor agreement.

CONCLUSION

Assessors were reliable and interchangeable. In a larger clinical context, results indicate that educating child health care nurses to assess infant cranial asymmetry can be used for early detection.

Effectiveness of conservative therapy and helmet therapy for positional cranial deformation

BACKGROUND

The authors investigated the effectiveness of conservative (repositioning therapy with or without physical therapy) and helmet therapy, and identified factors associated with treatment failure.

METHODS

A total of 4378 patients evaluated for deformational plagiocephaly and/or deformational brachycephaly were assigned to conservative (repositioning therapy, n = 383; repositioning therapy plus physical therapy, n = 2998) or helmet therapy (n = 997). Patients were followed until complete correction (diagonal difference <5 mm and/or cranial ratio <0.85) or 18 months. Rates of correction were calculated, and independent risk factors for failure were identified by multivariate analysis.

RESULTS

Complete correction was achieved in 77.1 percent of conservative treatment patients; 15.8 percent required transition to helmet therapy (n = 534), and 7.1 percent ultimately had incomplete correction. Risk factors for failure included poor compliance (relative risk, 2.40; p = 0.009), advanced age (relative risk, 1.20 to 2.08; p = 0.008), prolonged torticollis (relative risk, 1.12 to 1.74; p = 0.002), developmental delay (relative risk, 1.44; p = 0.042), and severity of the initial cranial ratio (relative risk, 1.41 to 1.64; p = 0.044) and diagonal difference (relative risk, 1.31 to 1.48; p = 0.027). Complete correction was achieved in 94.4 percent of patients treated with helmet therapy as first-line therapy and in 96.1 percent of infants who received helmets after failed conservative therapy (p = 0.375). Risk factors for helmet failure included poor compliance (relative risk, 2.42; p = 0.025) and advanced age (relative risk, 1.13 to 3.08; p = 0.011).

CONCLUSIONS

Conservative therapy and helmet therapy are effective for positional cranial deformation. Treatment may be guided by patient-specific risk factors. In most infants, delaying helmet therapy for a trial of conservative treatment does not preclude complete correction.
