Principles for Primary Care Screening in the Context of Population Health.

A key component of primary care pediatrics is health promotion through screening: applying a test or procedure to detect a previously unrecognized disease or disease risk. How do we decide whether to screen? In 1965, Wilson and Jungner published an influential set of screening principles focused on the health problem's importance, the screening tool's performance, and the evidence for treatment efficacy. However, if we want realistic estimates of the population effects of routine screening, we must also account for the health care system's real-world functioning and disparities in care. We offer revised principles to guide discussions about routine screening in the primary care setting. We add to Wilson and Jungner's principles: 1. A focus on life course epidemiology and its consequences for population health, 2. A need to screen for the early stages of chronic health problems, 3. A concern for screening's acceptability to providers and the community, 4. A recommendation for estimating the uncertainty in benefits and harms in evaluating screening, 5. Inclusion of systematic plans for population data collection and monitoring, and 6. Recognition that achieving population health improvement requires a high-performing system with sufficient throughput and monitoring to deliver accessible, affordable, and effective care, especially for the groups experiencing the greatest inequities in access. Above all, instead of assuming best practices in treatment delivery and monitoring after screening, we argue for realism about the health care system functioning in routine practice.

Geographic variation and sociodemographic correlates of prescription psychotropic drug use among children and youth in Ontario, Canada: a population-based study.

BACKGROUND: Population-based research examining geographic variability in psychotropic medication dispensing to children and youth and the sociodemographic correlates of such variation is lacking. Variation in psychotropic use could reflect disparities in access to non-pharmacologic interventions and identify potentially concerning use patterns. METHODS: We conducted a population-based study of all Ontario residents aged 0 to 24 years who were dispensed a benzodiazepine, stimulant, antipsychotic or antidepressant between January 1, 2018, and December 31, 2018. We conducted small-area variation analyses and identified determinants of dispensing using negative binomial generalized estimating equation models. RESULTS: The age- and sex-standardized rate of psychotropic dispensing to children and youth was 76.8 (range 41.7 to 144.4) prescriptions per 1000 population, with large variation in psychotropic dispensing across Ontario's census divisions. Males had higher antipsychotic [rate ratio (RR) 1.40; 95% confidence interval (CI) 1.36 to 1.44) and stimulant (RR 1.75; 95% CI 1.70 to 1.80) dispensing rates relative to females, with less use of benzodiazepines (RR 0.85; 95% CI 0.83 to 0.88) and antidepressants (RR 0.81; 95% CI 0.80 to 0.82). Lower antipsychotic dispensing was observed in the highest income neighbourhoods (RR 0.72; 95% CI 0.70 to 0.75) relative to the lowest. Benzodiazepine (RR 1.12; 95% CI 1.01 to 1.24) and stimulant (RR 1.11; 95% CI 1.01 to 1.23) dispensing increased with the density of mental health services in census divisions, whereas antipsychotic use decreased (RR 0.82; 95% CI 0.73 to 0.91). The regional density of child and adolescent psychiatrists and developmental pediatricians (RR 1.00; 95% CI 0.99 to 1.01) was not associated with psychotropic dispensing. CONCLUSION: We found significant variation in psychotropic dispensing among young Ontarians. Targeted investment in regions with long wait times for publicly-funded non-pharmacological interventions and novel collaborative service models may minimize variability and promote best practices in using psychotropics among children and youth.

Parenting during the COVID-19 pandemic: The sociodemographic and mental health factors associated with maternal caregiver strain.

INTRODUCTION: The COVID-19 pandemic has introduced new stressors for parents ("caregivers") that may affect their own and their child's mental health (MH). We explored self-reported levels of caregiver strain (parents' perceived ability to meet parenting demands), and the MH and sociodemographic factors of caregivers to identify predictors of strain that can be used to guide MH service delivery for families. METHODS: We administered a web-based survey to Ontario caregivers with a child between 4 and 25 years old, between April and June 2020. We analyzed information from 570 maternal caregivers on their sociodemographics, youngest (or only) child's MH, their own MH, and the degree of caregiver strain experienced since the pandemic. We used linear regressions (unadjusted and adjusted models) to explore the relationship between caregiver strain and sociodemographics, child MH and caregiver MH. RESULTS: Over 75% of participants reported "moderate-to-high" caregiver strain. More than 25% of caregivers rated their MH as "poor" and 20% reported moderate-to-severe anxiety. Forty-five percent of the variance in caregiver strain was accounted for by child age, caregiver anxiety, and multiple child and caregiver MH variables. Younger child age and higher caregiver anxiety were the greatest predictors of caregiver strain. CONCLUSION: We found a relationship between child age, child and caregiver MH variables, and caregiver strain. Given the interrelatedness of these factors, supporting caregivers' MH and lessening their role strain becomes critical for family well-being. Evidence-based individual, family, and public health strategies are needed to alleviate pandemic-related strain. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Health outcomes associated with emergency department visits by adolescents for self-harm: a propensity-matched cohort study.

BACKGROUND: Self-harm is increasing among adolescents, and because of changing behaviours, current data are needed on the consequences of self-harm. We sought to investigate the trends related to hospital presentation, readmission, patient outcome and medical costs in adolescents who presented with self-harm to the emergency department. METHODS: We used administrative data on 403 805 adolescents aged 13-17 years presenting to Ontario emergency departments in 2011-2013. Adolescents with self-harm visits were 1:2 propensity matched to controls with visits without self-harm, using demographic, mental health and other clinical variables. Five years after the index presentation, hospital or emergency department admission rates for self-harm, overall mortality, suicides and conservative cost estimates were compared between the 2 groups. RESULTS: Of 5832 adolescents who visited Ontario emergency departments in 2011-2013 after self-harm (1.4% of visits), 5661 were matched to 10 731 adolescents who presented for reasons other than self-harm. Adolescents who presented with self-harm had a shorter time to a repeat emergency department or hospital admission for self-harm (hazard ratio [HR] 4.84, 95% confidence interval [CI] 4.44-5.27), more suicides (HR 7.96, 95% CI 4.00-15.86), and higher overall mortality (HR 3.23, 95% CI 2.12-4.93; p < 0.001). The positive predictive value of self-harm-related emergency department visits for suicide was 0.7%. Adolescents with self-harm visits had mean 5-year estimates of health care costs of $30 388 compared with $19 055 for controls (p < 0.001). INTERPRETATION: Adolescents with emergency department visits for self-harm have higher rates of mortality, suicide and recurrent self-harm, as well as higher health care costs, than matched controls. Development of algorithms and interventions that can identify and help adolescents at highest risk of recurrent self-harm is warranted.

Partners for Kids Care Coordination: Lessons From the Field.

OBJECTIVE: The goal of this trial was to present a case study of care coordination for children and youth with special health care needs from an exclusively pediatric accountable care organization, and compare precare and postcare data on their use of inpatient and emergency department services. METHODS: This pre-post comparison of the health care utilization included a subset of 733 children enrolled in Partners for Kids care coordination funded through a delegation arrangement with several Medicaid managed care plans. We compared inpatient admissions, hospital bed days, 30-day hospital readmissions, and emergency department visits during the 6 months before their enrollment in the coordination program versus the 6 months after enrollment. RESULTS: Approximately 16 000 referrals to the Partners for Kids care coordination program were made for an estimated 12 000 children. A total of 3072 unique individual children were enrolled; the most common condition classification was mental, behavioral, and neurodevelopmental disorders (25% of enrolled children). Due to rapid turnover/churn in Medicaid managed care eligibility, the subset of children with continuous enrollment was limited to 733 children. Among this subset, the counts of inpatient admissions, bed days, and 30-day readmissions between the pre-enrollment and post-enrollment period decreased (P < .05). CONCLUSIONS: These results suggest that it is possible for an accountable care organization to reduce inpatient and emergency department utilization. Going forward, the most important tasks of the care coordination team are to overcome obstacles to referral and participation and to develop methods to achieve better measures of patient-reported outcomes.

Immune dysregulation and glucocorticoid resistance in minority and low income pregnant women.

Chronic prenatal stress contributes to poor birth outcomes for women and infants. Importantly, poor birth outcomes are most common among minority and low income women. To investigate underlying mechanisms, we tested the hypothesis that chronic stress related to minority or low income status is associated with glucocorticoid resistance as indicated by disruption in the cytokine-glucocorticoid feedback circuit. Home visits were conducted during which 3rd trimester pregnant women completed stress and depression surveys and provided blood for pro- and anti-inflammatory cytokines. Saliva was collected 5 times the preceding day for diurnal cortisol levels. For statistical analyses, women were grouped 3 ways, by race, income, and the presence or absence of either of those risk factors; this last group was labeled high or low general risk. Immune regulation was evaluated by evidence of a functioning negative feedback relationship between cytokines and cortisol. Of 96 participants, 18 were minority, 22 of low income, and 29 either minority or low income (high general risk). Pearson partial correlation identified a significant negative relationship between cortisol area under the curve (AUC) and pro- to anti-inflammatory cytokine ratios in the low general risk women (i.e., Caucasian, higher income) including IFNγ/IL10 (r=-0.73, p<0.0001), IL6/IL10 (r=-0.38, p=0.01), IL1ß/IL10 (r=-0.44, p=0.004) and TNFα/IL10 (r=-0.41; p=0.005); no such correlations existed in the high general risk women (i.e., minority, low income) for (IFNγ/IL10: r=-0.25, p=0.43; IL6/IL10: r=0.12, p=0.70; IL1 ß/IL10: r=0.05, p=0.87; TNFα/IL10: r=0.10; p=0.75), suggestive of glucocorticoid resistance. Cortisol levels throughout the day also were higher in minority and high general risk groups (p<0.05). Without cytokine glucocorticoid feedback, a pregnant woman's ability to regulate inflammation is limited, potentially contributing to adverse maternal and infant outcomes.

African-American/white differences in the age of menarche: accounting for the difference.

Lifetime health disparity between African-American and white females begins with lower birthweight and higher rates of childhood overweight. In adolescence, African-American girls experience earlier menarche. Understanding the origins of these health disparities is a national priority. There is growing literature suggesting that the life course health development model is a useful framework for studying disparities. The purpose of this study was to quantify the influence of explanatory factors from key developmental stages on the age of menarche and to determine how much of the overall race difference in age of menarche they could explain. The factors were maternal age of menarche, birthweight, poverty during early childhood (age 0 through 5 years), and child BMI z-scores at 6 years. The sample, drawn from the US National Longitudinal Surveys of Youth Child-Mother file, consisted of 2337 girls born between 1978 and 1998. Mean age of menarche in months was 144 for African-American girls and 150 for whites. An instrumental variable approach was used to estimate a causal effect of child BMI z-score on age of menarche. The instrumental variables were pre-pregnancy BMI, high gestational weight gain and smoking during pregnancy. We found strong effects of maternal age of menarche, birthweight, and child BMI z-score (-5.23, 95% CI [-7.35,-3.12]) for both African-Americans and whites. Age of menarche declined with increases in exposure to poverty during early childhood for whites. There was no effect of poverty for African-Americans. We used Oaxaca decomposition techniques to determine how much of the overall race difference in age of menarche was attributable to race differences in observable factors and how much was due to race dependent responses. The African-American/white difference in childhood BMI explained about 18% of the overall difference in age of menarche and birthweight differences explained another 11%.

Spatio-temporal clusters of new psychotropic medications among Michigan children insured by Medicaid.

PURPOSE: The prescription of psychotropic medications to children and adolescents has increased dramatically over the last decade. However, the development of disparities in prescribing is poorly understood. We examined whether clustering of utilization is a common phenomenon among early adopters of medications described the characteristics of clusters. METHODS: We obtained the complete Medicaid Analytic Extract (MAX) files for the State of Michigan between 1 January 2000 and 31 December 2003. We tracked the adoption of: aripiprazole, atomoxetine, escitalopram, methylphenidate OROS, and ziprasidone. We conducted retrospective, space-time analyses, scanning for clusters with high rates of prescribing. Chi(2) analyses were used to compare the attributes of patients living within clusters to patients living in the rest of the state for each medication. Clusters of utilization were identified via the spatial scan statistic. Analysis of variance (ANOVA) was then used to compare the numbers of mental health professionals per capita in geographic areas that did and did not demonstrate clustering of prescriptions for new psychotropic medications. RESULTS: All five medications exhibited space-time clustering within the first 90 days following the US Food and Drug Administration (FDA) approval. The Medicaid population surrounding Kalamazoo was more likely to receive a prescription on multiple occasions. Excluding ziprasidone, clusters were not associated with greater geographic access to mental health care professionals. CONCLUSIONS: Clustering of new prescriptions for psychotropic medications was a common phenomenon in this population. Surveillance and cluster identification allow the development of disparities to be studied. This information permits interventions to be targeted to locations prospectively.

Medicaid insurance policy for youths involved in the criminal justice system.

Juvenile justice and Medicaid agencies share an interest in serving delinquent youths, many of whom have a relatively poor health status. However, many state and local Medicaid policies result in these youths having no insurance coverage, making access to needed services difficult. A nationally representative survey of state and community juvenile justice and Medicaid agencies was conducted to assess Medicaid policies. Evidence from the survey suggests that in some areas delinquent youths are actively disenrolled from Medicaid benefits, and in others little effort is made to connect them to Medicaid coverage. Discrepancies between justice agency and Medicaid agency responses point to poor communication and coordination. Overall, the survey identified several opportunities for policy intervention to enhance access to services for justice-involved youths.
