Patient factors associated with delayed diagnosis of developmental dysplasia of the hip

Equity in the Developmental Dysplasia of the Hip (DDH) Diagnosis and Treatment: A Retrospective Cohort Study to Unravel the Effect of Area Deprivation and the Insurance Type

Background Timely diagnosis of developmental dysplasia of the hip (DDH) is crucial for implementing less invasive treatment. However, socioeconomic barriers may lead to late diagnoses. The Area Deprivation Index (ADI) is an indicator of the socioeconomic challenges experienced by patients and their families. The primary objective is to investigate if the age at which DDH is diagnosed and the treatment protocol are influenced by the ADI or the insurance type. Materials and methods Using International Classification of Diseases-Tenth Edition (ICD-10) codes, newly diagnosed DDH patients (age under 10 years) from 2020 to 2023 were retrospectively identified at our pediatric tertiary center. Patients were categorized into four groups based on ADI percentile: (1) 1-10th percentile, (2) 11-20th percentile, (3) 21-40th percentile, and (4) 41-100th percentile. They were also stratified by insurance type. Age at diagnosis and treatment protocol (non-operative vs. operative) were collected and compared between the different ADI groups and insurance groups. Operative treatment was defined as open reduction with or without femoral/pelvic osteotomy. Results A total of 327 patients satisfied the inclusion criteria and had available ADI scores for analysis. The average age at diagnosis was notably lower in ADI group 1 compared to all other ADI groups (p < 0.05) and considerably lower for patients with commercial insurance compared to those with public (p = 0.0002). The rate of surgical treatment was markedly lower in ADI group 1 compared to ADI groups 2 and 3 (both p < 0.05) and notably lower for those with commercial insurance compared to public (p = 0.0005). ADI groups 2-4 showed no significant differences in average age at diagnosis or surgical treatment rate. Conclusion The study demonstrates that socioeconomic factors affect the diagnosis and, consequently, the treatment course of DDH. Specifically, patients residing in areas with lower levels of deprivation tend to be diagnosed at a younger age and undergo surgical treatment less frequently.

The Impact of Maternal Age and Educational Level on Developmental Dysplasia of the Hip Diagnosis and Screening: A Descriptive Comparative Study

Background

Early and proper screening for developmental dysplasia of the hip (DDH) is very critical to prevent catastrophic complication on the developing hip joint. Many factors (either maternal or child-related) that hinder timely DDH screening have been previously investigated.

Methods

A cross-sectional descriptive study design was adopted. 175 babies presented for DDH screening coming with their mothers were investigated. Maternal age, age group, and educational level were recorded. In addition, multiple child-related variables such as age of screening, gender, positive family history, preterm delivery, and mode of delivery were recorded as well. Analysis for association between delayed vs. early screening was made against the maternal and the child-related variables.

Results

A total number of 175 children with their mothers were investigated. The mean maternal age was 27.9 years, about one third of the mothers had a graduate level of education (36.3%), while 41.1% had high school education, and 22.3% had middle school education. On the other hand, 40.0% of the investigated babies were first born and two thirds of our sample babies were females (66.9%). Of the included babies, 100 (57.1%) were screened at the appropriate 4-month age, while 75 (42.9%) missed the 4-month screening. Chi-square analysis showed that delayed DDH screening was associated with a lower maternal educational level (P ≤ 0.001), younger maternal age (P ≤ 0.001), and first born baby (P ≤ 0.001). Positive family history was protective against delayed DDH screening (P = 0.032).

Conclusion

The lower maternal educational level, younger maternal age group, and first born babies are risk factors for delayed DDH screening.

Is Preferred Language Other Than English Associated With Delayed Surgery After ACL Injury in Children and Adolescents?

BACKGROUND

Previous studies have investigated the impact of social determinants of health, such as the type of healthcare insurance and household income, on children and adolescents with ACL tears. However, despite the increasing incidence of ACL injury in young patients and a substantial proportion of families who may prefer languages other than English, the relationship between language and clinical care remains unclear.

QUESTIONS/PURPOSES

To investigate the relationship between language and the care of children and adolescents with ACL tears, we asked: (1) Is a preferred language other than English (PLOE) associated with a delay between ACL injury and surgery? (2) Is a PLOE associated with a greater odds of a patient experiencing a meniscal tear and undergoing a meniscectomy than in those who prefer English?

METHODS

We treated 591 patients surgically for ACL injuries between 2011 and 2021. Of those, we considered patients aged 18 years or younger who underwent primary ACL reconstruction for this retrospective, comparative study. Five percent (31 of 591) of patients were excluded because the date of injury was not clearly documented, 2% (11 of 591) were revision reconstructions, and 1% (6 of 591) underwent procedures that were intentionally delayed or staged, leaving 92% (543 of 591) for analysis. The mean age was 16 ± 2 years, and 51% (276 of 543) of patients were boys. The family's preferred language was noted, as were demographic data, time between injury and surgery, and intraoperative findings. A language other than English was preferred by 21% (113 of 543) of patients. Of these, 94% (106 of 113) preferred Spanish. In a univariate analysis, we used independent-samples t-tests, Mann-Whitney U-tests, and Fisher exact tests, as appropriate. Purposeful-entry multivariable regression analyses were used to determine whether PLOE was associated with increased time to surgery, concomitant meniscus injury, or performance of meniscectomy while adjusting for confounding variables. Variables were included in multivariable models if they met the threshold for statistical significance in univariate testing (p < 0.05).

RESULTS

The median time between injury and ACL reconstruction was shorter in families who preferred English compared with those with a PLOE (69 days [IQR 80] versus 103 days [IQR 107)]; p < 0.001). After controlling for potentially confounding variables like insurance and age, we found that patients whose families had a PLOE had greater odds of undergoing surgery more than 60 days after injury (OR 2.2 [95% CI 1.3 to 3.8]; p = 0.005) and more than 90 days after injury (OR 1.8 [95% CI 1.1 to 2.8]; p = 0.02). After controlling for insurance, age, and other factors, PLOE was not associated with surgical delay beyond 180 days, concomitant meniscal tears, or performance of meniscectomy.

CONCLUSION

In this study of children and adolescents undergoing primary ACL reconstruction, patients whose families prefer a language other than English experienced a longer delay between injury and surgery. In areas with a large proportion of families with a PLOE, partnerships with primary care clinicians, emergency departments, schools, athletic teams, and community organizations may improve efficiency in the care of children with ACL injuries. Clinicians proficient in other languages, reliable interpreter services, and translated references and resources may also be impactful. Our results suggest a need for further research on the experiences, needs, and long-term outcomes of these patients, as well as the association of preferred language with results after surgery.

Socioeconomic disparities in the utilization of spine augmentation for patients with osteoporotic fractures: an analysis of National Inpatient Sample from 2011 to 2015

BACKGROUND CONTENT

Vertebral augmentation procedures are used for treatment of osteoporotic compression fractures. Prior studies have reported disparities in the treatment of patients with osteoporotic vertebral fractures, particularly with regards to the use of vertebroplasty and kyphoplasty.

PURPOSE

The purpose of this study is to report updates in racial and health insurance inequalities of spine augmentation procedures in patients with osteoporotic fractures.

METHODS

With the use of the National Inpatient Sample, we identified hospitalized patients with osteoporotic fractures between the period of 2011 and 2015. Patients with spine augmentation, defined by the utilization of vertebroplasty and kyphoplasty, were also identified. Our primary outcome was defined as the utilization of spine augmentation procedures across ethnic (white, hispanic, black, and asian/pacific islander) and insurance (self-pay, private insurance, Medicare, and Medicaid) groups. Variables were identified from the NIS database using International Classification of Diseases, Ninth and Tenth diagnosis codes. Univariate and multivariate regression analysis was used for statistical analysis with p value <.05 considered significant. A subgroup analysis was performed across the utilization of kyphoplasty, vertebroplasty, and Medicare coverage.

RESULTS

We identified a total of 110,028 patients with a primary diagnosis of vertebral fracture between 2011 and 2015 (mean age: 74.4±13.6 years, 68% women). About 16,237 patients (14.8%) underwent any type of spine augmentation with over 75% of the patients receiving kyphoplasty. Multivariate analysis showed that black patients (odds ratio [OR]=0.64, 95% confidence interval [CI]: 0.58-0.70, p<.001), Hispanic patients (OR=0.79, 95% CI: 0.73-0.86, p<.001), and Asian/Pacific Islander (OR=0.79, 95% CI: 0.70-0.89, p<.001) had significantly lower odds for receiving any spine augmentation compared with white patients. Patients with Medicaid (OR=0.59, 95% CI: 0.53-0.66, p<.001), private insurance (OR=0.90, 95% CI: 0.85-0.96, p=.001), and those who self-pay (OR=0.57, 95% CI: 0.47-0.69, p<.001) had significantly lower odds of spine augmentation compared with those with Medicare. Comparative use of kyphoplasty was not significantly different between white and black patients (OR=0.85, 95% CI: 0.70-1.04, p=.12). However, Hispanic patients (OR=0.84, 95% CI: 0.71-0.99, p=.04) and Asian/Pacific Islander patients (OR=0.73, 95% CI: 0.58-0.92, p=.007) had significantly lower use of kyphoplasty compared with white patients. The comparative use of kyphoplasty among patients receiving spine augmentation was not significantly different across each insurances status when compared with patients with Medicare.

CONCLUSIONS

Our study suggests that racial and socioeconomic disparities continue to exist with the utilization of spine augmentation procedures in hospitalized patients with osteoporotic fractures.

Impact of Socioeconomic Status on Outcomes of Patients with Kawasaki Disease

OBJECTIVE

To evaluate the association of neighborhood socioeconomic status (SES) with time to intravenous immunoglobulin treatment, length of stay (LOS), and coronary artery aneurysms (CAAs) in patients with Kawasaki disease.

STUDY DESIGN

We examined the relationship of SES in 915 patients treated at a large academic center between 2000 and 2017. Neighborhood SES was measured using a US census-based score derived from 6 measures related to income, education, and occupation. Linear and logistic regression were used to examine the association of SES with number of days of fever at time of treatment, LOS, and CAA.

RESULTS

Patients in the lowest SES quartile were treated later than patients with greater SES (7 [IQR 5, 9] vs 6 [IQR 5, 8] days, P = .01). Patients in the lowest SES quartile were more likely to be treated after 10 days of illness, with an OR 1.9 (95% CI 1.3-2.8). In multivariable analysis, SES remained an independent predictor of the number of days of fever at time of treatment (P = .01). Patients in the lowest SES quartile had longer LOS than patients with greater SES (3 [IQR 2, 5] vs 3 [IQR 2, 4], P = .007). In subgroup analysis of white children, those in the lowest SES quartile vs quartiles 2-4 were more likely to develop large/giant CAA 17 (12%) vs 30 (6%), P = .03.

CONCLUSIONS

Lower SES is associated with delayed treatment, prolonged LOS, and increased risk of large/giant CAA. Novel approaches to diagnosis and education are needed for children living in low-SES neighborhoods.

Socioeconomic Risk Factors for Poor Outcomes of Developmental Dysplasia of the Hip

OBJECTIVE

To examine the relationship between socioeconomic factors and outcomes of developmental dysplasia of the hip (DDH).

STUDY DESIGN

A retrospective review of patients with DDH at a tertiary pediatric hospital from 2003 to 2012 with 2 years minimum follow-up was conducted. The relationship between socioeconomic factors with late presentation, treatment, and outcomes was examined. Socioeconomic factors included insurance status, language, and ethnicity.

RESULTS

In total, 188 patients met criteria. Patients with late presentations were more likely to be Hispanic (P = .02). However, public insurance and a non-English language were not associated with late presentation. Hispanic patients (P = .01) and patients with a non-English language (P = .01) had a lower nonoperative treatment success rate. Hispanic patients had more surgical procedures performed than non-Hispanic patients (P = .04). Patients with range of motion limitations were more likely to have public insurance (P = .05) and be Hispanic (P = .04). On multiple logistic regression analysis controlling for late presentation, patients with public insurance had increased odds of range of motion limitations (OR 2.22, P = .04). Patients with public insurance (OR 0.44, P = .04), a non-English primary language (OR 0.30, P < .01), and Hispanic ethnicity (OR 0.37, P = .01) had decreased odds of successful nonoperative treatment.

CONCLUSIONS

Public insurance, a non-English language, and Hispanic ethnicity are risk factors for inferior outcomes for DDH. When controlling for late presentation, these were significant risk factors for nonoperative treatment failure.
