Actionable Analysis: Toward a Jurisdictional Evaluation of Primary Care Access in the Community Context.

Primary care is the foundation of health care systems and has potential to alleviate inequities in population health. We examined multiple measures of adult primary care access, health status, and socioeconomic position at the New York City Council District level-a unit of analysis both relevant to and actionable by local policymakers. The results showed significant associations between measures of primary care access and health status after adjustment for socioeconomic factors. We found that an increase of 1 provider per 10 000 people was associated with a 1% decrease in diabetes rates and a 5% decrease in rates of adults without an influenza immunization. Furthermore, higher rates of primary care providers in high-poverty districts accepted Medicaid and had Patient-Centered Medical Home recognition, increasing constituent accessibility. Our findings highlight the significant contribution of primary care access to community health; policies and resource allocation must prioritize primary care facility siting and provider recruitment in low-access areas.

Beyond the bridge: evaluating a novel mental health program in the New York City jail system.

OBJECTIVES: We evaluated Beyond the Bridge, a novel mental health program in the New York City jail system designed to provide residentially based cognitive behavioral therapy in jail mental observation units. METHODS: We used propensity score matching and a dose-response analysis. Outcome measures included reduction in violent incidents and fights, reduction in uses of force by corrections officers, reduction in time spent on suicide watch and incidents of self-injurious behavior, and increased length of community survival. RESULTS: There were significant reductions in all outcomes when we compared program participants (n = 218) with an earlier cohort of patients residing on the mental observation unit before programming began (n = 413). However, when we compared program participants with a cohort of other patients residing on the units at the same time but who chose not to participate (n = 267), only time spent on suicide watch unit (rate ratio [RR] = 0.72; 95% confidence interval [CI] = 0.59, 0.89) and recidivism (RR = 0.70; 95% CI = 0.59,0.83) were significantly reduced. CONCLUSIONS: This evaluation and the model we piloted may provide useful information for other settings contemplating similar interventions.

Transitional care coordination in New York City jails: facilitating linkages to care for people with HIV returning home from Rikers Island.

New York City (NYC) jails are the epicenter of an epidemic that overwhelmingly affects Black and Hispanic men and offer a significant opportunity for public health intervention. The NYC Department of Health and Mental Hygiene instituted population based approaches to identify the HIV-infected, initiate discharge planning at jail admission, and facilitate post-release linkages to primary care. Using a caring and supportive 'warm transitions' approach, transitional care services are integral to continuity of care. Since 2010, over three-quarters of known HIV-infected inmates admitted to jails received discharge plans; 74 % of those released were linked to primary care. The EnhanceLink initiative's new Health Liaison, a lynchpin role, facilitated 250 court-led placements in medical alternatives to incarceration. Transitional care coordination programs are critical to facilitate continuity of care for people with chronic health conditions including the HIV-infected returning home from jail and for the public health of the communities to which they return.

Injury surveillance in New York City jails.

To characterize injuries occurring in jails, we analyzed injury report forms from the New York City jail system. We abstracted data from 4695 injury report forms representing 3863 patients. Of the injuries reported, 66% were classified as intentional. The 2 leading causes of injuries were inmate-on-inmate aggression (40%) and slips and falls (27%). Injuries place a considerable burden on jail health care systems, and there is a need for more studies on this problem and development of injury prevention programs.

Prevalence and predictors of residential health hazards: a pilot study.

This article reports the results of a pilot study designed to ascertain the prevalence of lead-based paint (LBP), vermin, mold, and safety conditions and hazards and to validate observations and self-reports against environmental sampling data. Data are based on a convenience sample of 70 dwellings in a low-income, urban neighborhood in Brooklyn, New York. The vast majority of residences (96%) contained multiple conditions and/or hazards: LBP hazards (80%), vermin (79%), elevated levels of airborne mold (39%), and safety hazards (100%). Observations and occupant reports were associated with environmental sampling data. In general, the more proximate an observed condition was to an actual hazard, the more likely it was to be associated with environmental sampling results (e.g., peeling LBP was associated with windowsill dust lead levels, and cockroach sightings by tenants were associated with Blatella germanica [Bla g 1] levels). Conversely, the more distal an observed condition was to an actual hazard, the less likely it was to be associated with environmental sampling results (e.g., water damage, alone, was not statistically associated with elevated levels of dust lead, Bla g 1, or airborne mold). Based on the findings from this pilot study, there is a need for industrial hygienists and others to adopt more comprehensive and integrative approaches to residential hazard assessment and remediation. Further research--using larger, randomly drawn samples, representing a range of housing types and geographical areas--is needed to clarify the relationship between readily observable conditions, occupant reports, and environmental sampling data and to assess the cumulative impact on human health.

Clozapine pharmacokinetics in children and adolescents with childhood-onset schizophrenia.

Clozapine (CLZ) dose-related adverse effects may be more common in children than adults, perhaps reflecting developmental pharmacokinetic (PK) differences. However, no pediatric CLZ PK data are available. Accordingly, we studied CLZ and its metabolites, norclozapine (NOR), and clozapine-N-oxide (NOX) in six youth, ages 9-16 years, with childhood onset schizophrenia (COS). At the time of the PK study, mean CLZ dose was 200 mg (3.4 mg/kg). Serum was collected during week 6 on CLZ before and 0.5-8 h after a morning dose. Serum concentrations were assayed by liquid chromatography/UV-detection. Mean concentration, area-under-the-curve (AUC), and clearance were calculated. CLZ clearance averaged 1.7 L/kg-h. NOR concentrations (410) exceeded CLZ (289) and NOX (63 ng/ml) and AUC(0-8h) of NOR (3,356) > CLZ (2,359) > NOX (559 ng/ml-h) [53, 38, and 9% of total analytes, respectively]. In adults, NOR serum concentrations on average are 10-25% < CLZ, differing significantly from our sample. Dose normalized concentrations of CLZ (mg/kg-d) did not vary with age and were similar to reported adult values. Clinical improvement seen in 5/6 patients correlated with serum CLZ concentrations. In addition, clinical response and total number of side effects correlated with NOR concentrations. NOR (a neuropharmacologically active metabolite) and free CLZ may contribute to the effectiveness and adverse effects in youth.

Fluoxetine pharmacokinetics in pediatric patients.

The objective of this study was to evaluate the pharmacokinetic profile of fluoxetine (FLX) and its major metabolite, norfluoxetine (NORFLX), in children and adolescent patients undergoing psychiatric treatment. Twenty-one pediatric subjects--10 children (6-12 years) and 11 adolescents (13-18 years)--were administered 20 mg FLX for 60 days, with sparse blood samples taken throughout the open-label study. Subjects contributed 168 plasma concentrations. Pharmacokinetic parameters were estimated using a mixed effects nonlinear model. Mean steady-state FLX and NORFLX of 127 ng/mL and 151 ng/mL, respectively, were achieved in children and adolescents after 4 weeks of treatment, with high between-patient variability. FLX was 2-fold higher and NORFLX was 1.7-fold higher in children relative to adolescents; however, when normalized to body weight, FLX and NORFLX were similar for both age groups. Age, body weight, body mass index, and body surface area, modeled independently as continuous variables, significantly improved the population pharmacokinetic model when evaluated as patient factors. Body weight was the covariate retained in the final model. In conclusion, children have 2-fold higher FLX and NORFLX relative to adolescents that appear to be related to indices of body size. The accumulation profile and steady-state concentrations in adolescents appear similar to those in adults.

Correlates of ADHD among children in pediatric and psychiatric clinics.

OBJECTIVE: Conventional wisdom among pediatricians has been that children with attention-deficit hyperactivity disorder (ADHD) who receive their diagnosis and are managed in the primary care setting have fewer comorbid psychiatric disorders and milder impairments than those seen in psychiatric clinics. The authors sought to determine whether comorbidity and clinical correlates of ADHD differ among children in these two settings. METHODS: A case-control study design was used. Participants were 522 children and adolescents of both sexes, six to 18 years of age, with (N=280) and without (N=242) ADHD. Participants were drawn from pediatric and psychiatric clinics in a tertiary care hospital and a health maintenance organization in a large metropolitan area. Assessments were conducted with standardized measures of psychiatric, cognitive, social, academic, and family function. RESULTS: The number, type, clusters, and age at onset of ADHD symptoms were nearly identical for youths at pediatric and psychiatric ascertainment sources. Regardless of source, participants with ADHD were significantly more likely than controls to have a higher prevalence of mood disorders, other disruptive behavior, anxiety disorders, and substance use disorders. Significant impairments of intellectual, academic, interpersonal, and family functioning did not differ between ascertainment sources. CONCLUSIONS: Children with ADHD from both psychiatric and pediatric practices have prototypical symptoms of the disorder; high levels of comorbidity with mood, anxiety, and disruptive behavior disorders; and impairments in cognitive, interpersonal, and academic function that do not differ by ascertainment source. These findings suggest that children cared for in pediatric practice have similar levels of comorbidity and dysfunction as psychiatrically referred youth.
