RESUMO

INTRODUCTION: Adverse childhood experiences (ACEs) are strongly correlated with many of the most common causes of preventable illness, preventable death, and health disparities. In January 2020, California launched the first statewide initiative to integrate ACE screening throughout its Medicaid system. A key element of the initiative was the California ACEs Learning and Quality Improvement Collaborative, a 48-clinic, 16-month learning collaborative. This evaluation aimed to determine whether developing a trauma-informed environment of care was associated with uptake of ACE screening. METHODS: Participants included 40 of 48 clinics that participated in the statewide learning collaborative. Clinics completed an assessment of progress in 5 essential components of trauma-informed health care at baseline and 1-year follow-up. Clinics tracked data on ACE screens completed on an ongoing basis and submitted data quarterly. A hierarchical linear model was used to examine the association between change in readiness for trauma-informed health care and change in quarterly screens. RESULTS: Readiness for trauma-informed health care increased for all participating clinics over the course of the learning collaborative. The average number of quarterly screens also increased, with considerable variability among clinics. Clinics with larger increases in readiness for trauma-informed health care had larger increases in quarterly screens. DISCUSSION: The findings align with long-standing recommendations for trauma screening to occur in the context of trauma-informed environments of care. CONCLUSION: A trauma-informed clinic is the foundation for successful adoption of ACE screening. ACE screening initiatives should include education and sufficient support for clinics to embrace a trauma-informed systems change process.

RESUMO

The purpose of this qualitative study was to elicit client perspectives on the Los Angeles County Full Service Partnership (FSP) program - an adaptation of Assertive Community Treatment (ACT). Semi-structured interviews were conducted with 20 FSP clients. Qualitative data were analyzed using thematic analysis. Two major themes were identified from the interview data: (1) Clients' acknowledgement of the material benefits of the FSP program; and (2) FSP's impact on restoring and stabilizing clients' social and treatment relationships. Interviewees greatly valued the material (i.e., basic needs, housing assistance) and relational (i.e., relationships with providers, restored personal relationships) aspects of the program, but did not ascribe the same degree of value to mental health treatment. Interviewees' emphases on material and relational aspects reflect the status of assertive mental health treatment as an intervention on intermediary determinants of health in the lives of persons diagnosed with serious mental illness.

RESUMO

The broad goals of New York State's Medicaid Section 1115 Waiver are to enroll a majority of Medicaid beneficiaries into managed care, increase access and service quality, and expand coverage to more low-income New Yorkers. The RAND Corporation was competitively selected as the independent evaluator to assess two components under this 1115 Demonstration Waiver: the Managed Long-Term Care (MLTC) program and the 12-month continuous eligibility policy, which guarantees enrollees Medicaid coverage regardless of changes in income in the 12 months after eligibility determination and enrollment. This final interim evaluation examines whether these two components have helped achieve the program's goals. The RAND team's analyses show that the Demonstration has expanded access to managed care through mandatory MLTC enrollment and 12-month continuous eligibility. The team found no evidence of a significant change in patient safety or quality of care. The authors note that, although this means that there is no evidence the Demonstration achieved the goal of improving quality of care, increasing access without compromising quality of care is a success in its own right.

RESUMO

This study was conducted to determine the feasibility of conducting a cost-benefit evaluation of federally-funded media campaigns encouraging mental health help-seeking among United States military personnel and veterans. To calculate the necessary sample size for the evaluation, we obtained campaign costs, and determined the number of treatment seekers needed for the campaign to break even with its cost and the associated population change that an evaluation would need to detect. The sample size needed for an evaluation with 80% power was greater than the total population of U.S. military personnel and veterans. Given that the necessary sample size exceeds the population to be sampled, an appropriately powered outcome evaluation is not feasible. Other programs that would be cost effective with extremely small effect sizes should not be subject to underpowered and thus inaccurate empirical outcome evaluation.

RESUMO

Los Angeles County used Mental Health Services Act (MHSA) funds to greatly expand access to Full-Service Partnership (FSP) services and offer new prevention and early intervention (PEI) services. This study examines the reach of key MHSA-funded activities and what the impact of those activities has been, with a focus on PEI programs for children and transition-age youth (TAY) and FSP programs for children, TAY, and adults. The evaluation found evidence that the Los Angeles County Department of Mental Health (LAC DMH) is reaching the highly vulnerable population it seeks to reach with its FSP and youth PEI programs. Furthermore, those reached by the programs experience improvements in their mental health and life circumstances. Refining data collection will enable more-thorough evaluation of processes of care and would inform the program's quality-improvement efforts.

RESUMO

This article provides information and recommendations regarding the evaluation design of the Certified Community Behavioral Health Clinic (CCBHC) demonstration. Mandated by Congress in Section 223 of the Protecting Access to Medicare Act of 2014, the CCBHC is a new model of specialty behavioral health clinic, designed to provide comprehensive and integrated care for adults with mental health or substance-use disorders and children with serious emotional distress. Certification criteria for the CCBHCs have been specified by Substance Abuse and Mental Health Services Administration covering six core areas: staffing; accessibility; care coordination; scope of services; quality and other reporting; and organizational authority, governance, and accreditation. In addition, services provided to Medicaid enrollees in CCBHCs will be reimbursed through one of two alternative prospective payment systems. At present, 24 states have been awarded grants to begin the planning process for implementing CCBHCs. Of these states, eight will be selected to participate in the demonstration project beginning in January 2017. Results from the evaluation will inform mandated reports to Congress over the two-year demonstration period and the three years following the end of the demonstration, providing information to policymakers on the program's impact and value. In addition, the results can inform the direction of future efforts at integration of behavioral health into the health care system at this critical time of transformation.

RESUMO

The use of direct-to-consumer telehealth, in which a patient has access to a physician via telephone or videoconferencing, is growing rapidly. A key attraction of this type of telehealth for health plans and employers is the potential savings involved in replacing physician office and emergency department visits with less expensive virtual visits. However, increased convenience may tap into unmet demand for health care, and new utilization may increase overall health care spending. We used commercial claims data on over 300,000 patients from three years (2011-13) to explore patterns of utilization and spending for acute respiratory illnesses. We estimated that 12 percent of direct-to-consumer telehealth visits replaced visits to other providers, and 88 percent represented new utilization. Net annual spending on acute respiratory illness increased $45 per telehealth user. Direct-to-consumer telehealth may increase access by making care more convenient for certain patients, but it may also increase utilization and health care spending.

RESUMO

Retail clinics have been viewed by policy makers and insurers as a mechanism to decrease health care spending, by substituting less expensive clinic visits for more expensive emergency department or physician office visits. However, retail clinics may actually increase spending if they drive new health care utilization. To assess whether retail clinic visits represent new utilization or a substitute for more expensive care, we used insurance claims data from Aetna for the period 2010-12 to track utilization and spending for eleven low-acuity conditions. We found that 58 percent of retail clinic visits for low-acuity conditions represented new utilization and that retail clinic use was associated with a modest increase in spending, of $14 per person per year. These findings do not support the idea that retail clinics decrease health care spending.

RESUMO

BACKGROUND: An increasing number of patients are visiting retail clinics for simple acute conditions. Physicians worry that visits to retail clinics will interfere with primary care relationships. No prior study has evaluated the impact of retail clinics on receipt of primary care. OBJECTIVE: To assess the association between retail clinic use and receipt of key primary care functions. DESIGN: We performed a retrospective cohort analysis using commercial insurance claims from 2007 to 2009. PATIENTS: We identified patients who had a visit for a simple acute condition in 2008, the "index visit". We divided these 127,358 patients into two cohorts according to the location of that index visit: primary care provider (PCP) versus retail clinic. MAIN MEASURES: We evaluated three functions of primary care: (1) where patients first sought care for subsequent simple acute conditions; (2) continuity of care using the Bice-Boxerman index; and (3) preventive care and diabetes management. Using a difference-in-differences approach, we compared care received in the 365 days following the index visit to care received in the 365 days prior, using propensity score weights to account for selection bias. KEY RESULTS: Visiting a retail clinic instead of a PCP for the index visit was associated with a 27.7 visits per 100 patients differential reduction (p < 0 .001) in subsequent PCP visits for new simple acute conditions. Visiting a retail clinic instead of a PCP was also associated with decreased subsequent continuity of care (10.9 percentage-point differential reduction in Bice-Boxerman index, p < 0 .001). There was no differential change between the cohorts in receipt of preventive care or diabetes management. CONCLUSIONS: Retail clinics may disrupt two aspects of primary care: whether patients go to a PCP first for new conditions and continuity of care. However, they do not negatively impact preventive care or diabetes management.

RESUMO

OBJECTIVES: To describe trends in retail clinic use among commercially insured patients and to identify which patient characteristics predict retail clinic use. STUDY DESIGN: Retrospective cohort analysis of commercial insurance claims sampled from a population of 13.3 million patients in 22 markets in 2007 to 2009. METHODS: We identified 11 simple acute conditions that can be managed at a retail clinic and described trends in retail clinic utilization for these conditions. We used multiple logistic regressions to identify predictors of retail clinic versus another care site for these conditions and assessed whether those predictors changed over time. RESULTS: Retail clinic use increased 10-fold from 2007 to 2009. By 2009, 6.9% of all visits for the 11 conditions were to a retail clinic. Proximity to a retail clinic was the strongest predictor of use. Patients living within 1 mile of a retail clinic were 7.5% more likely to use one than those living 10 to 20 miles away (P <.001). Women (+0.9%, P <.001), young adults (+1.6%, P <.001), patients without a chronic condition (+0.9%, P <.001), and patients with high incomes (+2.6%, P <.001) were more likely to use retail clinics. All these associations became stronger over time. There was no association between primary care physician availability and retail clinic use. CONCLUSIONS: If these trends continue, health plans will see a dramatic increase in retail clinic utilization. While use is increasing on average, it is particularly increasing among young, healthy, and higher income patients living close to retail clinics.

RESUMO

In principle, efforts to improve patient safety, if they are successful, should lead to reductions in claims of medical malpractice. In practice, however, this has not yet been systematically demonstrated to be so. The authors examined the relationship between safety outcomes in hospitals and malpractice claiming against providers, using administrative data and measures for California from 2001 to 2005. They found that decreases in the county-level frequency of adverse safety outcomes were positively and significantly associated with decreases in the volume of malpractice claims, as captured by records from four of the largest malpractice insurers in the state. This result suggests that policy options that improve patient safety may offer a new avenue for reducing malpractice pressure on physicians, at the same time that they improve clinical outcomes.

RESUMO

BACKGROUND: Previous research suggests that disparities in non-small-cell lung cancer (NSCLC) survival can be explained in part by disparities in the receipt of cancer treatment. Few studies, however, have considered race and sex disparities in the timing and appropriateness of treatment across stages of diagnosis. OBJECTIVE: To evaluate the relationship of sex and race with the receipt of timely and clinically appropriate NSCLC treatment for each stage of diagnosis. METHOD: Surveillance Epidemiology and End Result data linked to Medicare claims for beneficiaries diagnosed with NSCLC between 1995 and 1999 were used to evaluate the relationship between race and sex with timely and appropriate NSCLC treatment while controlling for other demographic characteristics, comorbidities, socioeconomic status, and provider supply (N = 22,145). RESULTS: Overall adjusted rates of timely and appropriate treatment are 37.2%, 58.1%, and 29.2% for Medicare beneficiaries diagnosed with stage I or II, III, and IV NSCLC, respectively. Among stage I or II patients, women were 25% less likely to receive timely surgical resection relative to men, and blacks were 66% less likely to receive timely and appropriate treatment than whites. Black men were least likely to receive resection (22.2% compared with 43.7% for white men). Blacks were 34% less likely to receive timely surgery, chemotherapy, or radiation for stage III disease and were 51% less likely to receive chemotherapy in a timely fashion for stage IV disease relative to whites. CONCLUSION: Significant variations in appropriate timely treatment were found within and across stages of diagnosis, confirming that sex and race differences in NSCLC treatment exist.

RESUMO

BACKGROUND: Socioeconomic status (SES) has well known associations with a variety of health conditions and behaviors in adults but is unknown in adolescents. METHODS: Multilevel analysis was conducted to examine the associations between individual and neighborhood-level measures of SES and physical activity and body mass index in a sample of 1554 6th grade girls selected at random from 36 middle schools across 6 geographic regions in the United States that participated in the Trial of Activity for Adolescent Girls (TAAG). Data on parental education and employment, and receipt of subsidized school lunch were collected by questionnaire. Neighborhood-level SES was measured by the Townsend Index. Nonschool physical activity levels were measured by accelerometer and type, location and context was measured using a 3 day physical activity recall (3DPAR). RESULTS: After controlling for race, lower parental education and higher levels of social deprivation were associated with higher BMI. In a model with both variables, effects were attenuated and only race remained statistically significant. None of the indices of SES were related to accelerometer measured physical activity. Bivariate associations with self-reported Moderate-Vigorous Physical Activity (MVPA) location and type (3DPAR) varied by SES. CONCLUSION: Among adolescent girls in the TAAG Study, the prevalence of overweight is high and inversely related to individual and neighborhood SES.

RESUMO

OBJECTIVES: We tested the relationship between urban or rural residence as defined by rural-urban commuting area codes and risk of mortality in a sample of Medicare beneficiaries with lung cancer. METHODS: We used Surveillance, Epidemiology, and End Results data linked with Medicare claims to build proportional hazards models. The models tested hypothesized relationships between individual and community characteristics and overall survival for a cohort of Medicare beneficiaries 65 years and older who were diagnosed with lung cancer between 1995 and 1999 (N=26073). RESULTS: We found no evidence that lung cancer patients in rural areas have poorer survival than those in urban areas. Rather, individual (Medicaid coverage) and regional (lower census tract-level median income) socioeconomic factors and a smaller supply of subspecialists per 10000 individuals 65 years and older were positively associated with a higher risk of mortality. CONCLUSIONS: Although urban versus rural residence did not directly influence survival, rural residents were more likely to live in poorer areas with a smaller supply of health care providers. Therefore, we still need to be aware of rural beneficiaries' potential disadvantage when it comes to receiving needed care in a timely fashion.

RESUMO

OBJECTIVES: To assess the accessibility and suitability of schools as recreational sites and to determine whether they are associated with young adolescent girls' weekend metabolic equivalent-weighted moderate-to-vigorous physical activity and body mass index (BMI). METHODS: We drew a half-mile (0.805 km) radius around the residences of participants in the Trial of Activity for Adolescent Girls (n=1556) in Maryland, South Carolina, Minnesota, Louisiana, California, and Arizona. We visited all schools and parks within the defined distance and documented their amenities and accessibility on Saturdays in Spring 2003. Staff gathered data on each girls' height and weight and used accelerometers to record weekend metabolic equivalent-weighted moderate-to-vigorous physical activity. RESULTS: Schools represented 44% of potential neighborhood sites for physical activity. However, a third of schools were inaccessible on the Saturday we visited. Neighborhoods with locked schools were primarily non-white, older, more densely populated, and of lower socioeconomic status. Though there was no relationship between school accessibility on Saturdays and weekend metabolic equivalent-weighted moderate-to-vigorous physical activity, the number of locked schools was associated with significantly higher body mass index. CONCLUSIONS: The lack of relationship between metabolic equivalent-weighted moderate-to-vigorous physical activity and school accessibility may imply that young adolescent girls do not identify schools as recreational resources. However, due to the association between body mass index and locked schools, efforts to stem the obesity epidemic should include making schools more accessible.

RESUMO

OBJECTIVES: Physical activity may be constrained or facilitated by local environments. The availability of neighborhood facilities for physical activity may be particularly relevant for youth, who are unable to drive and whose activity is often limited to the immediate distance they are able to walk or bicycle. Several studies have shown that proximity to recreational facilities and parks is one of the most important predictors of physical activity. Because the United States already has an extensive infrastructure of parks, with 70% of adults indicating that they live within walking distance of a park or playground, parks may be a potential venue for increasing physical activity. This might be particularly important for adolescent girls, whose physical activity levels decline substantially as they go through puberty. The goal of this study was to examine the association between park proximity, park type, and park features and physical activity in adolescent girls. PATIENTS AND METHODS: This was a cross-sectional study using baseline data from the Trial of Activity for Adolescent Girls. It included 1556 grade 6 girls who were randomly selected from 6 middle schools in each of the following 6 field site areas: Washington, DC, and Baltimore, Maryland; Columbia, South Carolina; Minneapolis, Minnesota; New Orleans, Louisiana; Tucson, Arizona; and San Diego, California. Girls wore accelerometers for 6 days to measure metabolic equivalent-weighted moderate-to-vigorous physical activity, a measure accounting for the volume and intensity of activity. Metabolic equivalent-weighted moderate-to-vigorous physical activity was calculated for the hours outside of school time using 2 different cutpoints, activity levels > or = 3.0 metabolic equivalents and > or = 4.6 metabolic equivalents, the latter indicating activity at the intensity of a brisk walk or higher. We mapped all of the parks within 1 mile of each girl's home. Trained staff used a checklist to document the presence of facilities and amenities at each park, including passive amenities, such as drinking fountains, restrooms, and areas with shade, as well as active amenities like basketball courts, multipurpose fields, playgrounds, and tennis courts. RESULTS: Mean nonschool metabolic equivalent-weighted moderate/vigorous physical activity, using the 4.6 metabolic equivalent cutoff, was 611.1 minutes (range: 49.7-4718.6 metabolic equivalent minutes per 6 days) and 1704.8 metabolic equivalent minutes per 6 days (range: 276.2-5792.6 metabolic equivalent minutes per 6 days) when using the 3.0 metabolic equivalent cutpoint. Many girls had multiple parks within a 1-mile radius of their homes: 57% had > or = 1 type of park, the majority being neighborhood or community parks; 42% had between 1 and 3 parks, 37% had > or = 4 parks, and 14% had > or = 8 parks. The type, number, and specific parks features were associated with girls' nonschool metabolic equivalent-weighted moderate/vigorous physical activity. At the 4.6 metabolic equivalent cutpoint, higher levels of nonschool metabolic equivalent-weighted moderate/vigorous physical activity were associated with both neighborhood and community parks (22 metabolic equivalent minutes) and miniparks (40 metabolic equivalent minutes). Each park, regardless of type, in the half-mile around each girl's home was associated with an increase in nonschool metabolic equivalent-weighted moderate/vigorous physical activity by 2.8% or 17.2 nonschool minutes of metabolic equivalent-weighted moderate/vigorous physical activity per 6 days. Beyond a half-mile, each park increased nonschool metabolic equivalent-weighted moderate/vigorous physical activity by 1.1% or 6.7 metabolic equivalent minutes per 6 days. For the average girl with 3.5 parks within a 1-mile radius of home, the presence of parks accounted for 36.5 extra nonschool metabolic equivalent minutes per 6 days, approximately 6% of total nonschool metabolic equivalent-weighted moderate/vigorous physical activity. Using the 3.0 metabolic equivalent cutpoint, this sums to an additional 68 metabolic equivalent minutes of nonschool metabolic equivalent-weighted moderate/vigorous physical activity over 6 days, or 4% of the total. The most common amenities in the parks were playgrounds, multipurpose fields, and picnic areas. Slightly more than one third of girls lived within a half-mile of a park with a basketball court, and > 20% had access to walking paths and tennis courts in their local park. Higher levels of nonschool metabolic equivalent-weighted moderate/vigorous physical activity per 6 days were associated with walking paths (13 metabolic equivalent minutes), running tracks (82 metabolic equivalent minutes), playgrounds (28 metabolic equivalent minutes), and basketball courts (30 metabolic equivalent minutes). Parks with streetlights and floodlights were also associated with an increase of 18 and 22 minutes of nonschool metabolic equivalent-weighted moderate/vigorous physical activity, respectively. With the 3.0 metabolic equivalent cutoff for metabolic equivalent-weighted moderate/vigorous physical activity, additional nonschool metabolic equivalent minutes more than doubled when girls had miniparks (92 metabolic equivalent minutes), natural resource areas (36 metabolic equivalent minutes), walking paths (59 metabolic equivalent minutes), and running tracks (208 metabolic equivalent minutes) within a half-mile of their homes. Skateboard areas and special-use parks were negatively associated with nonschool metabolic equivalent-weighted moderate/vigorous physical activity in adolescent girls. CONCLUSIONS: Adolescent girls who live near more parks, particularly near those with amenities that are conducive to walking and with active features, engage in more nonschool metabolic equivalent-weighted moderate/vigorous physical activity than those with fewer parks. Whether this is because of actual use of the parks or neighborhood choice could not be determined. Although the magnitude of the association between parks and additional minutes of metabolic equivalent-weighted moderate/vigorous physical activity was small for an individual, amounting to an average of 4%-6% of a girl's total nonschool metabolic equivalent-weighted moderate/vigorous physical activity, it is likely to have a large population-level association. Because of the potential population level impact, the use of parks to promote physical activity should be further studied.
