Association between body mass index and posterior spine fusion among patients with adolescent idiopathic scoliosis.

INTRODUCTION: Previous studies have found mixed associations between body mass index (BMI) and adolescent idiopathic scoliosis (AIS) incidence and progression. The aim of this study was to examine the association between BMI and the incidence of posterior spine fusion (PSF) among pediatric patients with AIS. METHODS: This was a retrospective cohort study of patients diagnosed with AIS at a single large tertiary care center between January 1, 2014 and December 31, 2020. BMI-for-age percentiles were used to categorize BMI into four categories: underweight (<5th percentile), healthy weight (≥5th to <85th percentile), overweight (≥85th to <95th percentile), and obese (≥95th percentile). Chi-square and t-tests were used to compare distributions of baseline characteristics by incident PSF outcome status. Multivariable logistic regression assessed the association between BMI category at baseline and incident PSF adjusting for sex, age at diagnosis, race/ethnicity, health insurance type, vitamin D supplementation, and low vitamin D levels. RESULTS: A total of 2,258 patients met the inclusion criteria with 2,113 patients (93.6%) who did not undergo PSF during the study period and 145 patients (6.4%) who did undergo PSF. At baseline, 7.3% of patients were categorized as underweight, 73.2% were healthy weight, 10.2% were overweight, and 9.3% were obese. Compared to those in the healthy weight group, there was no significant association between PSF and being underweight (adjusted odds ratio [AOR] 1.64, 95% CI 0.90-2.99, p = 0.107), being overweight (AOR 1.25, 95% CI 0.71-2.20, p = 0.436), or being obese (AOR 1.19, 95% CI 0.63-2.27, p = 0.594). CONCLUSIONS: This study did not find a statistically significant association between underweight, overweight, or obese BMI category and incident PSF among patients with AIS. These findings add to the current mixed evidence on the relationship between BMI and surgical risk and may support the recommendation of conservative treatment to patients regardless of BMI.

Young Adult Perspectives on Sex, Dating, and PrEP Use During the Pandemic and Improving the Future of PrEP Care.

Few studies have researched young adults' experiences taking HIV pre-exposure prophylaxis (PrEP) after the start of California's COVID-19 shelter-in-place (SIP) orders. The purpose of this study was to examine the experiences of young adults with sex, dating, and PrEP use during SIP and their perceptions on how to improve PrEP care in this age group. In this mixed-methods study, PrEP users ages 18-29 living in California between April 2020 and June 2021 completed a quantitative survey (N = 37) and one-on-one qualitative interviews (N = 18). Over half of survey participants reported trouble accessing PrEP care during SIP, citing difficulty obtaining medication refills, clinic appointments, and access to completing lab work. In qualitative interviews, participants expressed their preferences for more accessible PrEP service delivery across the PrEP care continuum. Despite pandemic SIP orders and trouble accessing PrEP services, young adults continued to engage in sexual behaviors.

Usability and Utility of Human Immunodeficiency Virus Pre-exposure Prophylaxis Clinical Decision Support to Increase Knowledge and Pre-exposure Prophylaxis Initiations among Pediatric Providers.

OBJECTIVES: An effective clinical decision support system (CDSS) may address the current provider training barrier to offering preexposure prophylaxis (PrEP) to youth at risk for human immunodeficiency virus (HIV) infection. This study evaluated change in provider knowledge and the likelihood to initiate PrEP after exposure to a PrEP CDSS. A secondary objective explored perceived provider utility of the CDSS and suggestions for improving CDSS effectiveness. METHODS: This was a prospective study using survey responses from a convenience sample of pediatric providers who launched the interruptive PrEP CDSS when ordering an HIV test. McNemar's test evaluated change in provider PrEP knowledge and likelihood to initiate PrEP. Qualitative responses on CDSS utility and suggested improvements were analyzed using framework analysis and were connected to quantitative analysis elements using the merge approach. RESULTS: Of the 73 invited providers, 43 had available outcome data and were included in the analysis. Prior to using the CDSS, 86% of participants had never been prescribed PrEP. Compared to before CDSS exposure, there were significant increases in the proportion of providers who were knowledgeable about PrEP (p = 0.0001), likely to prescribe PrEP (p < 0.0001) and likely to refer their patient for PrEP (p < 0.0001). Suggestions for improving the CDSS included alternative "triggers" for the CDSS earlier in visit workflows, having a noninterruptive CDSS, additional provider educational materials, access to patient-facing PrEP materials, and additional CDSS support for adolescent confidentiality and navigating financial implications of PrEP. CONCLUSION: Our findings suggest that an interruptive PrEP CDSS attached to HIV test orders can be an effective tool to increase knowledge and likelihood to initiate PrEP among pediatric providers. Continual improvement of the PrEP CDSS based on provider feedback is required to optimize usability, effectiveness, and adoption. A highly usable PrEP CDSS may be a powerful tool to close the gap in youth PrEP access and uptake.

Pediatric Provider Utilization of a Clinical Decision Support Alert and Association with HIV Pre-exposure Prophylaxis Prescription Rates.

OBJECTIVES: An electronic clinical decision support (CDS) alert can provide real-time provider support to offer pre-exposure prophylaxis (PrEP) to youth at risk for human immunodeficiency virus (HIV). The purpose of this study was to evaluate provider utilization of a PrEP CDS alert in a large academic-community pediatric network and assess the association of the alert with PrEP prescribing rates. METHODS: HIV test orders were altered for patients 13 years and older to include a hard-stop prompt asking if the patient would benefit from PrEP. If providers answered "Yes" or "Not Sure," the CDS alert launched with options to open a standardized order set, refer to an internal PrEP specialist, and/or receive an education module. We analyzed provider utilization using a frequency analysis. The rate of new PrEP prescriptions for 1 year after CDS alert implementation was compared with the year prior using Fisher's exact test. RESULTS: Of the 56 providers exposed to the CDS alert, 70% (n = 39) responded "Not sure" to the alert prompt asking if their patient would benefit from PrEP, and 54% (n = 30) chose at least one clinical support tool. The PrEP prescribing rate increased from 2.3 prescriptions per 10,000 patients to 6.6 prescriptions per 10,000 patients in the year post-intervention (p = 0.02). CONCLUSION: Our findings suggest a knowledge gap among pediatric providers in identifying patients who would benefit from PrEP. A hard-stop prompt within an HIV test order that offers CDS and provider education might be an effective tool to increase PrEP prescribing among pediatric providers.

Associations between State-Level High School HIV Education Policies and Adolescent HIV Risk Behaviors.

BACKGROUND: School-based human immunodeficiency virus (HIV) education can reach most adolescents, but inconsistencies exist in state-level content policies. The purpose of this study was to evaluate the associations between state-level high school HIV education policies and adolescent HIV risk behaviors. METHODS: This was a cross-sectional analysis of the 2019 Youth Risk Behavior Survey linked to the Guttmacher Institute Sex and HIV Education report. Logistic regression models examined the associations of state-level HIV education mandates and content policies with 3 HIV risk behaviors: (1) 4 or more lifetime sexual partners; (2) substance use before last sex; (3) condomless last sex. RESULTS: Across 33 states, 128,986 high school students were included. Multivariable adjusted models demonstrated no associations between mandated HIV education and risk behaviors. Covering abstinence along with other safe sex options was associated with lower odds, whereas stressing abstinence was associated with higher odds of at least 4 lifetime sexual partners and condomless last sex. Discriminatory sexual orientation content was associated with increased condomless last sex; associations for all HIV risk behaviors were stronger among sexual minority youth. CONCLUSIONS: Increased HIV risk behaviors associated with state policies stressing abstinence or requiring discriminatory sexual orientation content support the need for comprehensive and inclusive HIV education.
