Confronting Systemic Racism in Occupational Therapy: A Mixed Methods Study

This study aimed to examine how occupational therapists and students perceive systemic racism in occupational therapy practice and the effectiveness and impact of the delivery of a keynote address on confronting systemic racism in practice delivered to occupational therapists and students. The study aimed to help inform future efforts in creating a more diverse and inclusive profession at the practice, policy, and education level by providing input into the challenges and opportunities that occupational therapists and students face when reckoning with issues of racism in practice. A mixed methodology research design was used with Likert-style scale and open-ended questions delivered via online survey. Eighty-nine occupational therapists and students completed the online survey. Most of the respondents reported responding favorably to the keynote address and shared sentiment that it could be a difficult and uncomfortable topic, yet it was important to discuss because of its impact on the profession and the clients occupational therapists serve

Suicide Attempts Among a Cohort of Transgender and Gender Diverse People

INTRODUCTION: Transgender and gender diverse people often face discrimination and may experience disproportionate emotional distress that leads to suicide attempts. Therefore, it is essential to estimate the frequency and potential determinants of suicide attempts among transgender and gender diverse individuals. METHODS: Longitudinal data on 6,327 transgender and gender diverse individuals enrolled in 3 integrated healthcare systems were analyzed to assess suicide attempt rates. Incidence was compared between transmasculine and transfeminine people by age and race/ethnicity and according to mental health status at baseline. Cox proportional hazards models examined rates and predictors of suicide attempts during follow-up. Data were collected in 2016, and analyses were conducted in 2019. RESULTS: During follow-up, 4.8% of transmasculine and 3.0% of transfeminine patients had at least 1 suicide attempt. Suicide attempt rates were more than 7 times higher among patients aged45 years, more than 3 times higher among patients with previous history of suicide ideation or suicide attempts than among those with no such history, and 2-5 times higher among those with 1-2 mental health diagnoses and more than 2 mental health diagnoses at baseline than among those with none. CONCLUSIONS: Among transgender and gender diverse individuals, younger people, people with previous suicidal ideation or attempts, and people with multiple mental health diagnoses are at a higher risk for suicide attempts. Future research should examine the impact of gender-affirming healthcare use on the risk of suicide attempts and identify targets for suicide prevention interventions among transgender and gender diverse people in clinical settings

Parent intentions to vaccinate children with autism spectrum disorder against COVID-19.

PurposeThe purpose of this study was to investigate associations between parent vaccine confidence and intention to have their child with autism vaccinated against COVID-19.Design and methodsA cross-sectional, web-based survey was conducted from May to July 2021 with parents of children with autism spectrum disorder (N = 322) who were members of an integrated healthcare system in Southern California.ResultsApproximately 35% of parents intended to vaccinate their child against COVID-19. In adjusted models, positive vaccine beliefs-but not belief in vaccine harm, healthcare provider trust, or parent vaccination status-were associated with intention to vaccinate.ConclusionsThough parents usually trust recommendations from pediatric healthcare providers to make decisions about their child's health, these findings suggest that relying on trusted relationships alone may not be sufficient when discussing COVID-19 vaccines and that additional education to bolster vaccine confidence may be needed.Practice implicationsPediatric healthcare providers should reinforce the benefits of vaccines for parents who are undecided about COVID-19 vaccines for their children and provide education and evidence-based recommendations to parents who hold erroneous vaccine beliefs about risks, benefits, and current evidence, especially those related to autism

Real-world evidence of quadrivalent meningococcal conjugate vaccine safety in the United States: a systematic review

Two quadrivalent meningococcal conjugate vaccines (MenACWY) that prevent invasive meningococcal disease caused by N. meningitidis serogroups A, C, Y, and W have been licensed in the U.S. in the past 10–15 years. We systematically reviewed published studies conducted in the U.S. to evaluate the real-world safety evidence of meningococcal conjugate vaccines. We performed a literature search in PubMed of publications from 01/01/2005 to 02/29/2020 and identified 18 studies meeting inclusion criteria. Populations included high-risk persons aged 2 months to 10 years, adolescents/adults aged ≥11 years, pregnant populations, and hematopoietic cell transplant recipients. We extracted information about study setting, study design, exposure, outcomes, comparison group, follow-up/look back period, study population, sample size, available demographic/indication information, results, key conclusion, and reference. These published studies found no new significant safety concerns related to MenACWY. Consideration for future research includes a post-licensure safety evaluation of a new MenACWY product approved in April 2020

Patient Outcomes After Applied Behavior Analysis for Autism Spectrum Disorder

ObjectivesThe purpose of this study was to examine patterns of service receipt and patient outcomes for children receiving applied behavior analysis (ABA) for autism spectrum disorder (ASD) in an integrated health care system in which commercially insured children were covered by a state autism mandate.MethodsThis retrospective, observational study used a random sample of children with ASD (3-17 yrs) who were members of a large integrated health care system in Southern California and referred for ABA between January 2016 and November 2018. From the 4145 children referred, a random stratified sample of 334 was selected to extract data from clinical reports over 24 months of services. The primary outcome measures were time in ABA and child adaptive behavior.ResultsThirteen percent of the sample never received ABA after referral. Of those who were referred for ABA, 66% initiated ABA and remained in services for 12 months, whereas less than half (46%) remained in services for 24 months. Having a history of special education was associated with longer time spent in ABA, whereas having a single parent was associated with discontinuation of ABA. A minority of children received a full ABA dose (28%), but the lowest functioning children still experienced clinically significant adaptive behavior gains after 24 months of ABA (p = 0.02).ConclusionIn a health system implementation of ABA for children with ASD, there were high rates of ABA discontinuation and low ABA dosing. These challenges may diminish the potential benefits of ABA, even in a context in which there is mandated commercial insurance coverage

Habilitative Teletherapy for Children with Autism Spectrum Disorder: A Survey of Parents

ObjectiveThe purpose of this study was to investigate whether service losses during the coronavirus disease 2019 (COVID-19) pandemic were associated with worsened parent mental health or child behavioral health among families of children with autism spectrum disorder and to identify factors associated with favorable parent appraisals of habilitative teletherapy (applied behavior analysis; speech, occupational, physical therapy) for their child.MethodThis web-based survey study was conducted from May to July 2021 with parents whose children were receiving habilitative therapy for autism from an integrated health system. A total of 322 parents responded to the survey (20% response rate). The outcome variables were pandemic-related parent mental health, pandemic-related child behavioral health, and appraisal of habilitative teletherapy. Predictors were COVID-19-related services changes in health care or child care, COVID-19 history (COVID-19 stress, testing positive for COVID-19), and child autism factors (autistic behaviors, caregiving strain).ResultsLoss of regular child care was associated with higher odds of worsened parent mental health (odds ratio [OR] = 2.7, 95% confidence interval [CI] = 1.5-4.8); higher levels of caregiving strain were associated with worsened child behavioral health (OR = 2.3, 95% CI = 1.4-3.8). Higher levels of COVID-19 stress were associated with more favorable appraisals of telehealth (β = 0.4, p < 0.01), whereas higher caregiving strain scores were associated with less favorable appraisals of telehealth (β = -0.2, p < 0.01).ConclusionDuring COVID-19, caregiving factors were associated with worsened parent mental health and worsened child behavioral health, and telehealth is not preferred by all families. Policy interventions to support caregivers, such as affordable, high-quality child care and paid family leave, are a high priority
