Attitudes and Behaviors of Physical Activity in Children with Cerebral Palsy: Findings from PLAY Questionnaire.

To investigate the domains of physical activity in children with cerebral palsy (CP) and to compare these findings to typically developed (TD) children. Methods: A cross-sectional study design. Responses of the four domains in Play Lifestyle and Activity in Youth (PLAY) questionnaire were descriptively analyzed and compared between children with CP (GMFCS I-II) and TD children. Results: Fifty-three children with CP (N = 53, 36 males and 17 females, age of 8.4 ± 1.7 years) and 58 TD children (N = 58, 34 males and 24 females, age of 7.6 ± 1.4 years) participated in this study. In analyses of daily behavior, reported participation in weekly (adaptive) physical education (PE) and sports were more frequent in children with CP (0.6 ± 0.5 days per week) compared to TD children (0.4 ± 0.6 days per week, p = 0.040). Outside play time including free play, organized (adaptive) sports and recess were higher in children with CP (2.7 ± 0.8 days per week) than TD children (2.4 ± 0.7 days per week, p = 0.022). About motivation/attitudes, a higher proportion of TD children feel sad if they are not able to play sports during the day (74.1%) compared to children with CP (48.7%, p < 0.001). Conclusion: Physical activity level was comparable between children with CP and age-matched TD children, while TD children showed higher scores in knowledge and understanding, motivation/attitudes, and physical competence.

Barriers to Discharge After Hip Reconstruction Surgery in Non-ambulatory Children With Neurological Complex Chronic Conditions.

BACKGROUND: Hip reconstruction surgery in patients with neurological complex chronic conditions (CCC) is associated with prolonged hospitalization and extensive resource utilization. This population is vulnerable to cognitive, developmental, and medical comorbidities which can increase length of stay (LOS). The aims of this study were to characterize barriers to discharge for a cohort of children with neurological CCC undergoing hip reconstruction surgery and to identify patient risk factors for prolonged hospitalization and delayed discharge. METHODS: Retrospective chart review of nonambulatory patients with neurological CCC undergoing hip reconstruction surgery between 2007-2016 was conducted. Hospitalization ≥1 day past medical clearance was characterized as delayed discharge. Barriers were defined as unresolved issues at the time of medical clearance and categorized as pertaining to the caregiver and patient education, durable medical equipment, postdischarge transportation/placement, and patient care needs. RESULTS: The cohort of 116 patients was 53% male, 16% non-English speaking, and 49% Gross Motor Function Classification System (GMFCS) V with the mean age at surgery of 9.1±3.64 years. Median time from admission to medical clearance was 5 days with median LOS of 6 days. Approximately three-quarters of patients experienced delayed discharge (73%) with barriers identified for 74% of delays. Most prevalent barriers involved education (30%) and durable medical equipment (29%). Postdischarge transportation and placement accounted for 26% of barriers and 3.5 times longer delays ( P <0.001). Factors associated with delayed discharge included increased medical comorbidities ( P <0.05) and GMFCS V ( P <0.001). Longer LOS and medical clearance times were found for female ( P =0.005), older age ( P <0.001), bilateral surgery ( P =0.009), GMFCS V ( P =0.003), and non-English-speaking patients ( P <0.001). CONCLUSIONS: Patients with neurological CCC frequently encounter postoperative barriers contributing to increased LOS and delayed discharge. Patients that may be at higher risk for prolonged hospitalization and greater resource utilization include those who are female sex, adolescent, GMFCS V, non-English speaking, have additional comorbidities, and are undergoing bilateral surgery. Standardized preoperative assessment of educational needs, perioperative equipment requirements, and posthospital transportation may decrease the LOS, reduce caregiver and patient burden/distress, cost, and ultimately reduce variation in care delivery.

Pediatric Venous Thromboembolism: Different Rates of Incidence, Anatomic Locations, and Risk Factors Between Orthopaedic and Nonorthopaedic Related Patients.

BACKGROUND: The prevalence of venous thromboembolism (VTE) may be increasing in children; however, scarce literature exists comparing incidence rates between pediatric orthopaedic patients and other pediatric patients. The purpose of this study was to compare the incidence, anatomic locations, and risk factors of VTEs between orthopaedic and nonorthopaedic pediatric related patients to determine if important differences exist. METHODS: Computed tomography and ultrasound data were reviewed for children (below 19 y old) with a diagnosed VTE between January 1, 2009 and December 31, 2016. Demographic and clinical data, including VTE anatomic location and risk factors, were recorded. Two major cohorts were identified: orthopaedic-related (ORTH) and nonorthopaedic-related (NORTH) VTEs. Incidence rates were estimated and risk factors were compared using χ2 testing. RESULTS: There were 373 children diagnosed with a VTE (average age 10.3 y) of a total of 810,097 treated as in-patients for an incidence rate of 4.60 per 10,000 cases (95% confidence interval=4.15 to 5.10 per 10,000 cases). The rate of ORTH VTEs (28 of 188,669 orthopaedic patients, 1.48 per 10,000 cases) was significantly lower than that of NORTH VTEs (345 of 621,428 nonorthopaedic patients, 5.55 per 10,000 cases; P<0.001). For the ORTH cohort, there was a significant difference in the proportion of deep vein thrombosis in the lower extremity (91%) compared with the upper extremity (9%) (P<0.001), while a more even distribution of NORTH deep vein thrombosis in the upper (50%) and lower (41%) extremities was appreciated. The primary risk factors for ORTH VTEs included surgery (93%; P<0.001), change in ambulatory status (61%; P<0.001), and trauma (18%; P<0.001), while the primary risk factors for NORTH VTEs included intravenous peripheral inserted central catheter/central line (61%; P<0.001) and cancer (27%; P=0.001). CONCLUSIONS: Pediatric ORTH VTEs have a significantly lower incidence rate and different primary risk factors than those of NORTH VTEs. This information is useful for health care providers when making decisions regarding risk and prophylaxis in pediatric patients with orthopaedic and nonorthopaedic conditions.

Inter-rater and Intrarater Reliabilities of the Identification of a "Gothic Arch" in the Acetabulum of Children With Cerebral Palsy.

BACKGROUND: Progressive hip displacement in children with cerebral palsy (CP) is monitored by measuring migration percentage (MP) on anteroposterior (AP) pelvis radiographs. Accurate measurement of MP requires the lateral margin of the ossified acetabulum to be identified for the placement of Perkin's line. It has been suggested that when there is an erosion of the acetabular rim, described as a gothic arch, the midpoint of the arch be used for the placement of Perkin's line. However, this requires that there be agreement on what constitutes a gothic arch. The purpose of this study was to evaluate the inter-rater and intrarater reliabilities of identifying a gothic arch on pelvis radiographs. METHODS: An online survey with 100 AP pelvis images (200 hips) of children with CP was sent to international experts. Participants were asked to identify which hip(s) had a gothic arch (left, right, both, and neither). The Fleiss κ statistic for inter-rater reliability was calculated. Eight weeks later, the images were shuffled and redistributed to calculate intrarater reliability. RESULTS: The initial survey was completed by 10 participants with 9 participants completing the second survey. The average inter-rater κ value was 0.18 [95% confidence interval (CI), 0.14-0.23] and 0.19 (95% CI, 0.14-0.24) for the 2 surveys, respectively. Among the pediatric orthopaedic surgeons subgroup, the κ values were 0.06 (95% CI, 0.02-0.1) and 0.08 (95% CI, 0.03-0.13). The average intrarater reliability κ value was 0.61 (95% CI, 0.2-1), ranging from 0.32 to 0.86. CONCLUSIONS: There were poor inter-rater and moderate intrarater reliabilities in identifying a gothic arch on AP pelvis radiographs in children with CP. Further characterization and clarification of what constitutes a gothic arch are required. The lack of agreement on the identification of a gothic arch may negatively impact the measurement of MP and referrals to a pediatric orthopaedic surgeon.

Hip Reconstruction in Nonambulatory Children With Cerebral Palsy: Identifying Risk Factors Associated With Postoperative Complications and Prolonged Length of Stay.

BACKGROUND: The purpose of this study is to examine the relationship between preoperative comorbidities, surgical complications, and length of stay (LOS) after hip reconstruction in nonambulatory children with cerebral palsy (CP). METHODS: This single-center retrospective cohort study included 127 patients undergoing hip surgery between 2007 and 2016 who were diagnosed with CP (GMFCS IV/V). The cohort was 54% Gross Motor Function Classification System (GMFCS) V with an average age at surgery of 9 years (range, 3-19 y). Preoperative comorbidities included: presence of a gastrostomy tube, respiratory difficulty requiring positive-pressure ventilation or tracheostomy, history of seizures, and nonverbal status. Complications were dichotomized into major and minor complications according to severity. Multivariable general linear modeling was used to identify factors associated with complications and prolonged LOS. RESULTS: The median LOS in the hospital was 6 days (intequartile range, 5-9 d). The majority of procedures (72%) involved both the femur and acetabulum and 82% of surgeries were performed bilaterally. Patients who experienced a major complication were mostly GMFCS level V and were more likely to spend time in intensive care unit than postanesthetic care unit (P=0.001). Multivariable analysis for a major complication determined that the addition of each comorbid risk fact increased the odds of developing a major complication by 2.6 times (odds ratio, 2.64; 95% confidence interval, 1.56-4.47; P<0.001) regardless of GMFCS level. Multivariable analysis for prolonged LOS determined that major complications (P<0.001), bilaterality (P=0.01), age (P=0.02), female sex (P=0.01), and GMFCS V (P<0.001) were all factors that increased LOS. Migration percentage, acetabular index odds ratio, and pelvic obliquity were not associated with prolonged LOS or the presence of a major complication. CONCLUSIONS: From our analysis, the authors found that a patient's premorbid comorbidities were more predictive of the likelihood of sustaining a major complication than their GMFCS level. Identifying high-risk patients preoperatively may help reduce complications and LOS, which ultimately will improve the quality of care the authors deliver to nonambulatory children with CP undergoing hip reconstruction surgery. LEVEL OF EVIDENCE: Level III-retrospective cohort study.
