Advocacy interventions to reduce or eliminate violence and promote the physical and psychosocial well-being of women who experience intimate partner abuse.

BACKGROUND: Intimate partner abuse is common worldwide, damaging the short- and long-term physical, mental, and emotional health of survivors and children. Advocacy may contribute to reducing abuse, empowering women to improve their situation by providing informal counselling and support for safety planning and increasing access to different services. Advocacy may be a stand-alone service, accepting referrals from healthcare providers, or part of a multi-component (and possibly multi-agency) intervention provided by service staff or others. OBJECTIVES: To assess the effects of advocacy interventions within or outside healthcare settings in women who have experienced intimate partner abuse. SEARCH METHODS: In April 2015, we searched CENTRAL, Ovid MEDLINE, EMBASE, and 10 other databases. We also searched WHO ICTRP, mRCT, and UK Clinical Research Network (UKCRN), and examined relevant websites and reference lists with forward citation tracking of included studies. For the original review we handsearched six key journals. We also contacted first authors of eligible papers and experts in the field. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials comparing advocacy interventions for women with experience of intimate partner abuse versus no intervention or usual care (if advocacy was minimal and fewer than 20% of women received it). DATA COLLECTION AND ANALYSIS: Two review authors independently assessed risk of bias and undertook data extraction. We contacted authors for missing information needed to calculate statistics for the review and looked for adverse events. MAIN RESULTS: We included 13 trials involving 2141 participants aged 15 to 65 years, frequently having low socioeconomic status.The studies were quite heterogeneous in terms of methodology, study processes and design, including with regard to the duration of follow-up (postintervention to three years), although this was not associated with differences in effect. The studies also had considerable clinical heterogeneity in relation to staff delivering advocacy; setting (community, shelter, antenatal, healthcare); advocacy intensity (from 30 minutes to 80 hours); and abuse severity. Three trials evaluated advocacy within multi-component interventions. Eleven measured some form of abuse (eight scales), six assessed quality of life (three scales), and six measured depression (three scales). Countries and ethnic groups varied (one or more minority ethnic groups in the USA or UK, and local populations in Hong Kong and Peru). Setting was associated with intensity and duration of advocacy.Risk of bias was high in five studies, moderate in five, and low in three. The quality of evidence (considering multiple factors such as risk of bias, study size, missing data) was moderate to low for brief advocacy and very low for intensive advocacy. Incidence of abuse Physical abuseModerate quality pooled data from two healthcare studies (moderate risk of bias) and one community study (low risk of bias), all with 12-month follow-up data, showed no effect on physical abuse for brief (< 12 hours) advocacy interventions (standardised mean difference (SMD) 0.00, 95% confidence interval (CI) - 0.17 to 0.16; n = 558). One antenatal study (low risk of bias) showed an association between brief advocacy and reduced minor physical abuse at one year (mean difference (MD) change - 1.00, 95% CI - 1.82 to - 0.18; n = 110). An antenatal, multi-component study showed a greater likelihood of physical abuse ending (odds ratio (OR) 0.42, 95% CI 0.23 to 0.75) immediately after advocacy (number needed to treat (NNT) = 8); we cannot exclude impact from other components.Low to very low quality evidence from two intensive advocacy trials (12 hours plus duration) showed reduced severe physical abuse in women leaving a shelter at 24 months (OR 0.39, 95% CI 0.20 to 0.77; NNT = 8), but not at 12 or 36 months. Sexual abuseMeta-analysis of two studies (n = 239) showed no effect of advocacy on sexual abuse (SMD - 0.12, 95% CI - 0.37 to 0.14), agreeing with the change score (MD - 0.07, 95% CI - 0.30 to 0.16) from a third study and the OR (0.96, 95% CI 0.44 to 2.12) from a fourth antenatal, multi-component study. Emotional abuseOne study in antenatal care, rated at low risk of bias, showed reduced emotional abuse at ≤ 12-month follow-up (MD (change score) - 4.24, 95% CI - 6.42 to - 2.06; n = 110). Psychosocial health Quality of lifeMeta-analysis of two studies (high risk of bias) showed intensive advocacy slightly improved overall quality of life of women recruited from shelters (MD 0.23, 95% CI 0.00 to 0.46; n = 343) at 12-month follow-up, with greater improvement in perceived physical quality of life from a primary care study (high risk of bias; MD 4.90, 95% CI 0.98 to 8.82) immediately postintervention. Depression Meta-analysis of two studies in healthcare settings, one at high risk of bias and one at moderate risk, showed that fewer women developed depression (OR 0.31, 95% CI 0.15 to 0.65; n = 149; NNT = 4) with brief advocacy. One study at high risk of bias reported a slight reduction in depression in pregnant women immediately after the intervention (OR 0.51, 95% CI 0.20 to 1.29; n = 103; NNT = 8).There was no evidence that intensive advocacy reduced depression at ≤ 12-month follow-up (MD - 0.14, 95% CI - 0.33 to 0.05; 3 studies; n = 446) or at two years (SMD - 0.12, 95% CI - 0.36 to 0.12; 1 study; n = 265). Adverse effectsTwo women died, one who was murdered by her partner and one who committed suicide. No evidence links either death to study participation. AUTHORS' CONCLUSIONS: Results suggest some benefits from advocacy. However, most studies were underpowered. Clinical and methodological heterogeneity largely precluded pooling of trials. Therefore, there is uncertainty about the magnitude of benefit, the impact of abuse severity, and the setting.Based on the evidence reviewed, intensive advocacy may improve short-term quality of life and reduce physical abuse one to two years after the intervention for women recruited from domestic violence shelters or refuges. Brief advocacy may provide small short-term mental health benefits and reduce abuse, particularly in pregnant women and for less severe abuse.

Does Screening or Providing Information on Resources for Intimate Partner Violence Increase Women's Knowledge? Findings from a Randomized Controlled Trial.

BACKGROUND: Screening for IPV in health care settings might increase women's knowledge or awareness around its frequency and its impact on health. When IPV is disclosed, assuring women it is not their fault should improve their knowledge that IPV is the perpetrator's responsibility. Providing information about IPV resources may also increase women's knowledge about the availability of solutions. METHODS: Women (n=2708) were randomly assigned to one of three groups: (1) partner violence screen plus video referral and list of local partner violence resources if screening was positive (n=909); (2) partner violence resource list only without screen (n=893); and (3) a no-screen, no-partner violence resource list control group (n=898). One year later, 2364 women (87%) were re-contacted and asked questions assessing their knowledge of the frequency of partner violence, its impact on physical and mental health, the availability of resources to help women experiencing partner violence, and that it is the perpetrator's fault. RESULTS: There were no differences between women screened and provided with a partner violence resource list compared to a control group as to women's knowledge of the frequency of IPV, its impact on physical or mental health, or the availability of IPV services in their community. However, among women who experienced IPV in the year before or year after enrolling in the trial, those who were provided a list of IPV resources without screening were significantly less likely to know that IPV is not the victim's fault than those in the control or list plus screening conditions. CONCLUSIONS: The results of this study suggest that providing information on partner violence resources, with or without asking questions about partner violence, did not result in improved knowledge.

Effect of screening for partner violence on women's quality of life: a randomized controlled trial.

CONTEXT: Although partner violence screening has been endorsed by many health organizations, there is insufficient evidence that it has beneficial health outcomes. OBJECTIVE: To determine the effect of computerized screening for partner violence plus provision of a partner violence resource list vs provision of a partner violence list only on women's health in primary care settings, compared with a control group. DESIGN, SETTING, AND PARTICIPANTS: A 3-group blinded randomized controlled trial at 10 primary health care centers in Cook County, Illinois. Participants were enrolled from May 2009-April 2010 and reinterviewed 1 year (range, 48-56 weeks) later. Participants were English- or Spanish-speaking women meeting specific inclusion criteria and seeking clinical services at study sites. Of 3537 women approached, 2727 were eligible, 2708 were randomized (99%), and 2364 (87%) were recontacted 1 year later. Mean age of participants was 39 years. Participants were predominantly non-Latina African American (55%) or Latina (37%), had a high school education or less (57%), and were uninsured (57%). INTERVENTION: Randomization into 3 intervention groups: (1) partner violence screen (using the Partner Violence Screen instrument) plus a list of local partner violence resources if screening was positive (n = 909); (2) partner violence resource list only without screen (n = 893); and (3) no-screen, no-partner violence list control group (n=898). MAIN OUTCOME MEASURES: Quality of life (QOL, physical and mental health components) was the primary outcome, measured on the 12-item Short Form (scale range 0-100, mean of 50 for US population). RESULTS: At 1-year follow-up, there were no significant differences in the QOL physical health component between the screen plus partner violence resource list group (n = 801; mean score, 46.8; 95% CI, 46.1-47.4), the partner violence resource list only group (n = 772; mean score, 46.4; 95% CI, 45.8-47.1), and the control group (n = 791; mean score, 47.2; 95% CI, 46.5-47.8), or in the mental health component (screen plus partner violence resource list group [mean score, 48.3; 95% CI, 47.5-49.1], the partner violence resource list only group [mean score, 48.0; 95% CI, 47.2-48.9], and the control group [mean score, 47.8; 95% CI, 47.0-48.6]). There were also no differences between groups in days unable to work or complete housework; number of hospitalizations, emergency department, or ambulatory care visits; proportion who contacted a partner violence agency; or recurrence of partner violence. CONCLUSIONS: Among women receiving care in primary care clinics, providing a partner violence resource list with or without screening did not result in improved health.

Comparative cost analysis of housing and case management program for chronically ill homeless adults compared to usual care.

OBJECTIVE: To assess the costs of a housing and case management program in a novel sample-homeless adults with chronic medical illnesses. DATA SOURCE: The study used data from multiple sources: (1) electronic medical records for hospital, emergency room, and ambulatory medical and mental health visits; (2) institutional and regional databases for days in respite centers, jails, or prisons; and (3) interviews for days in nursing homes, shelters, substance abuse treatment centers, and case manager visits. Total costs were estimated using unit costs for each service. STUDY DESIGN: Randomized controlled trial of 407 homeless adults with chronic medical illnesses enrolled at two hospitals in Chicago, Illinois, and followed for 18 months. PRINCIPAL FINDINGS: Compared to usual care, the intervention group generated an average annual cost savings of (-)$6,307 per person (95 percent CI: -16,616, 4,002; p = .23). Subgroup analyses of chronically homeless and those with HIV showed higher per person, annual cost savings of (-)$9,809 and (-)$6,622, respectively. Results were robust to sensitivity analysis using unit costs. CONCLUSION: The findings of this comprehensive, comparative cost analyses demonstrated an important average annual savings, though in this underpowered study these savings did not achieve statistical significance.

Comparison of screening and referral strategies for exposure to partner violence.

BACKGROUND: Although under debate, routine screening for intimate partner violence (IPV) is recommended in health care settings. This study explored the utility of different screening and referral strategies for women exposed to IPV in primary health care. METHODS: Using a randomized controlled trial design we compared two screening strategies (health care providers [HCP] versus audio computer-assisted self-interviews [A-CASI]) and three referral strategies (HCP alone, A-CASI referral with HCP endorsement, and A-CASI alone). English-speaking women who were 18 years and older and were attending women's health clinics at a public hospital were eligible to participate. Participants were randomly assigned to one of three study groups (HCP screen and referral, A-CASI screen and referral with HCP referral endorsement, and A-CASI screen and referral). Women were reinterviewed by telephone 1 week later. The primary outcome was rate of IPV disclosure; secondary outcomes were screening mode preference, reactions to IPV screening, and use of referral resources. RESULTS: Of the 129 eligible women, 126 women were enrolled (98%); 102 women (81% of those enrolled) completed the follow-up telephone interview. Disclosure rates were higher for women screened with A-CASI compared with HCP-screened women (21% vs. 9%; p = .07). Screening mode preference, impact of screening (positive and negative reactions), and rates of use of referral resources were similar between study groups. CONCLUSION: A-CASI tended to yield higher rates of IPV disclosure and similar rates of use of referral resources. A-CASI technology may be a practical way to screen for IPV.

Evaluation of an asthma medication training program for immigrant Mexican community health workers.

BACKGROUND: Community health workers (CHWs) are frontline public health workers who connect immigrant communities with health care services. Although CHW asthma interventions have been shown to improve some outcomes, their ability to change medication adherence remains unclear. OBJECTIVE: Our goal was to determine if intensive asthma medication training resulted in objective improvements in asthma medication instruction abilities for immigrant Mexican CHWs. METHODS: Eleven CHWs participated in a 15-hour training course conducted in only Spanish. The course covered asthma pathophysiology, reliever and controller medications, medication technique, and self-management skills. Before and after the training, CHWs completed a written asthma knowledge test and were tested on medication delivery technique using a demonstrator metered dose inhaler (MDI), spacer, and dry powder inhaler (DPI). After the training, CHWs performed a standardized role play to assess their ability to deliver medication instruction. At follow-up evaluations, the CHWs described benefits and weaknesses of the training. RESULTS: Before the training, the median correct medication technique scores were: MDI = 25%, spacer = 0%, and DPI = 0%. After the training, the median scores were: MDI = 69%, spacer = 64%, and DPI = 67% (p < .01). On the role plays, all CHWs were scored as "Demonstrates adequate understanding of a complicated skill" and four were "Ready for the field on a clinical trial." The CHWs described specific application of training skills during the subsequent delivery of an asthma intervention. CONCLUSION: This training and follow-up evaluation provide objective evidence of improved asthma medication knowledge, delivery technique, and instruction abilities in immigrant Mexican CHWs. With proper training, CHWs can assist families to understand and correctly use complicated asthma medications.

Concordance in the measurement of quality of life and health indicators between two methods of computer-assisted interviews: self-administered and by telephone.

PURPOSE: The aim of this study was to establish the concordance for quality of life (QOL), disability, and use of health service indicators between two modes of computer-assisted interviews: audio-computer-assisted self-interview (A-CASI) and computer-assisted telephone interview (CATI). High concordance between these modes of data collection would allow comparisons and interchangeable use in cross-sectional or longitudinal assessments. METHODS: Adult English-speaking women (n = 126) were enrolled from women's health clinics at a public hospital. QOL using the short form 12 version 2, disability (days missed from work, inability to do household activities), and utilization of health services (number of emergency room visits and hospitalizations) were assessed first with A-CASI at the time of enrollment and again (n = 102) with CATI 1 week later. Participants assessed with both modes were 38 years old on average, predominantly African-American, 41% had a high school education or less, and 61% were uninsured. Lin's concordance correlation coefficient or Cohen's kappa was calculated to establish concordance between paired A-CASI and CATI assessments. RESULTS: Concordance between the two interview methods ranged from fair to substantial for the QOL components, (concordance correlation coefficient [CCC] of .76 and .87, respectively), the QOL subscales, and disability indices (CCC range; .53-.91). For health services utilization, there was moderate concordance for emergency room visits (CCC = .70) but only slight concordance for the number of hospitalizations in the past year (CCC = .37). CONCLUSIONS: Administering surveys through a telephone or self-administered computer-assisted interview resulted in moderate to substantial agreement for the short form QOL components and fair to substantial for the QOL subscales and disability measures. These findings suggest A-CASI and CATI can be used interchangeably for some QOL scales.

Obesity and asthma morbidity in a community-based adult cohort in a large urban area: the Chicago Initiative to Raise Asthma Health Equity (CHIRAH).

BACKGROUND: Urban minority populations experience increased rates of obesity and increased asthma prevalence and severity. Objective. The authors sought to determine whether obesity, as measured by body mass index (BMI), was associated with asthma quality of life or asthma-related emergency department (ED)/urgent care utilization in an urban, community-based sample of adults. METHODS: This is a cross-sectional analysis of 352 adult subjects (age 30.9 +/- 6.1, 77.8% females, forced expiratory volume in one second (FEV(1))% predicted = 87.0% +/- 18.5%) with physician-diagnosed asthma from a community-based Chicago cohort. Outcome variables included the Juniper Asthma Quality of Life Questionnaire (AQLQ) scores and health care utilization in the previous 12 months. Bivariate tests were used as appropriate to assess the relationship between BMI or obesity status and asthma outcome variables. Multivariate regression analyses were performed to predict asthma outcomes, controlling for demographics, income, depression score, and beta-agonist use. RESULTS: One hundred ninety-one (54.3%) adults were obese (BMI > 30 kg/m(2)). Participants with a higher BMI were older (p = .008), African American (p < .001), female (p = .002), or from lower income households (p = .002). BMI was inversely related to overall AQLQ scores (r = -.174, p = .001) as well as to individual domains. In multivariate models, BMI remained an independent predictor of AQLQ. Obese participants were more likely to have received ED/urgent care for asthma than nonobese subjects (odds ratio [OR] = 1.8, p = .036). CONCLUSIONS: In a community-based sample of urban asthmatic adults, obesity was related to worse asthma-specific quality of life and increased ED/urgent care utilization. However, compared to other variables measured such as depression, the contribution of obesity to lower AQLQ scores was relatively modest.

Intimate partner violence towards women.

INTRODUCTION: Between 10% and 70% of women may have been physically or sexually assaulted by a partner at some stage, with assault rates against men reported at about one quarter of the rate against women. In at least half of people studied, the problem lasts for 5 years or more. Women reporting intimate partner violence (IPV) are more likely than other women to complain of poor physical or mental health, and of disability. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions initiated by healthcare professionals aimed at female victims of intimate partner violence? We searched: Medline, Embase, The Cochrane Library, and other relevant databases up to September 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). RESULTS: We found 26 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: advocacy; career counselling plus critical consciousness awareness; cognitive behavioural counselling; cognitive trauma therapy; counselling; nurse support and guidance; peer support groups; safety planning; and shelters.

The influence of caregiver's psychosocial status on childhood asthma and obesity.

BACKGROUND: The prevalence of childhood asthma and childhood overweight has increased in the last 2 decades, disproportionately burdening ethnic minority children and those living in poverty with no clear understanding of underlying mechanisms. OBJECTIVE: To explore the influence of demographic variables, childhood obesity (adjusted body mass index > or = 95th percentile), caregivers' smoking status, and caregiver psychosocial status on asthma severity and asthma control in an urban sample of children with persistent asthma. METHODS: Child (with asthma)-caregiver dyads were recruited from public and archdiocese schools in Chicago, Illinois, as part of the Chicago Initiative to Raise Asthma Health Equity. Data were collected as part of the baseline face-to-face surveys conducted within the community. RESULTS: The 531 dyads were divided into 2 groups: 294 taking controller medications were in the asthma control analyses and 237 taking rescue medications only were in the asthma severity analyses. In multivariate models, asthma control was significantly worse in obese children (odds ratio [OR], 1.89; 95% confidence interval [CI], 1.17-3.05), African American children (OR, 2.16; 95% CI, 1.05-4.46), and those with caregivers who had higher stress (OR, 1.09; 95% CI, 1.01-1.18). Older children had better control (OR, 0.79; 95% CI, 0.69-0.90). Children with caregivers who wanted more asthma-specific social support were more likely to have moderate to severe asthma (OR, 2.07; 95% CI, 1.06-4.05). CONCLUSION: In this community-based sample of children with active asthma, asthma control and asthma severity were associated with different factors. Caregiver variables were significant in both outcomes, and childhood obesity was associated only with poor asthma control.

Ethnic disparities in asthma morbidity in Chicago.

RATIONALE: The role of ethnicity and socioeconomic status in explaining variations in asthma morbidity is unclear. OBJECTIVES: To describe the magnitude of ethnic disparities in asthma morbidity in Chicago and to determine whether differences in socioeconomic status explain these disparities. METHODS: We conducted a survey of 561 school-age children and 353 young adults with asthma and measured their self-reported ethnicity, socioeconomic status (using 11 variables), and asthma morbidity (symptom frequency, asthma-specific quality of life, and frequency of severe asthma exacerbations). MEASUREMENTS AND MAIN RESULTS: White children and adults had better asthma-specific quality of life and fewer severe asthma exacerbations compared to black and Hispanic children and adults. White children also had fewer days with asthma symptoms, but among adults there were no ethnic differences in the frequency of asthma symptoms. Socioeconomic status explained a large portion of the ethnic disparities in asthma quality of life but explained little of the disparities in other aspects of asthma morbidity. CONCLUSIONS: There are large disparities across ethnic groups in Chicago in asthma quality of life and in the frequency of severe exacerbations. Differences in socioeconomic status do not fully explain these disparities.

Effect of a housing and case management program on emergency department visits and hospitalizations among chronically ill homeless adults: a randomized trial.

CONTEXT: Homeless adults, especially those with chronic medical illnesses, are frequent users of costly medical services, especially emergency department and hospital services. OBJECTIVE: To assess the effectiveness of a case management and housing program in reducing use of urgent medical services among homeless adults with chronic medical illnesses. DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial conducted at a public teaching hospital and a private, nonprofit hospital in Chicago, Illinois. Participants were 407 social worker-referred homeless adults with chronic medical illnesses (89% of referrals) from September 2003 until May 2006, with follow-up through December 2007. Analysis was by intention-to-treat. INTERVENTION: Housing offered as transitional housing after hospitalization discharge, followed by placement in long-term housing; case management offered on-site at primary study sites, transitional housing, and stable housing sites. Usual care participants received standard discharge planning from hospital social workers. MAIN OUTCOME MEASURES: Hospitalizations, hospital days, and emergency department visits measured using electronic surveillance, medical records, and interviews. Models were adjusted for baseline differences in demographics, insurance status, prior hospitalization or emergency department visit, human immunodeficiency virus infection, current use of alcohol or other drugs, mental health symptoms, and other factors. RESULTS: The analytic sample (n = 405 [n = 201 for the intervention group, n = 204 for the usual care group]) was 78% men and 78% African American, with a median duration of homelessness of 30 months. After 18 months, 73% of participants had at least 1 hospitalization or emergency department visit. Compared with the usual care group, the intervention group had unadjusted annualized mean reductions of 0.5 hospitalizations (95% confidence interval [CI], -1.2 to 0.2), 2.7 fewer hospital days (95% CI, -5.6 to 0.2), and 1.2 fewer emergency department visits (95% CI, -2.4 to 0.03). Adjusting for baseline covariates, compared with the usual care group, the intervention group had a relative reduction of 29% in hospitalizations (95% CI, 10% to 44%), 29% in hospital days (95% CI, 8% to 45%), and 24% in emergency department visits (95% CI, 3% to 40%). CONCLUSION: After adjustment, offering housing and case management to a population of homeless adults with chronic medical illnesses resulted in fewer hospital days and emergency department visits, compared with usual care. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00490581.

Intimate partner violence towards women.

INTRODUCTION: Between 10-69% of women may have been physically or sexually assaulted by a partner at some stage, with assault rates against men reported at about a quarter of the rate against women. In at least half of people studied, the problem lasts for 5 years or more. Women reporting intimate partner violence (IPV) are more likely than other women to complain of poor physical or mental health, and of disability. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions initiated by healthcare professionals aimed at female victims of intimate partner violence? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2008 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). RESULTS: We found 25 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: advocacy; career counselling plus critical consciousness awareness; cognitive behavioural counselling; cognitive trauma therapy; counselling; nurse support and guidance; peer support groups; safety planning; and shelters.

The health impact of supportive housing for HIV-positive homeless patients: a randomized controlled trial.

OBJECTIVES: We assessed the health impact of a housing and case management program, the Chicago Housing for Health Partnership, for homeless people with HIV. METHODS: HIV-positive homeless inpatients at a public hospital (n = 105) were randomized to usual care or permanent housing with intensive case management. The primary outcome was survival with intact immunity, defined as CD4 count > or = 200 and viral load < 100,000. Secondary outcomes were viral loads, undetectable viral loads, and CD4 counts. RESULTS: Outcomes were available for 94 of 105 enrollees (90%). Of 54 intervention participants, 35 (65%) reached permanent housing in program housing agencies. After 1 year, 55% of the intervention and 34% of the usual care groups were alive and had intact immunity (P = .04). Seventeen intervention (36%) and 9 usual care (19%) participants had undetectable viral loads (P = .051). Median viral loads were 0.89 log lower in the intervention group (P = .03). There were no statistical differences in CD4 counts. CONCLUSIONS: Homelessness is a strong predictor of poor health outcomes and complicates the medical management of HIV. This housing intervention improved the health of HIV-positive homeless people.

The impact of an enhanced interpreter service intervention on hospital costs and patient satisfaction.

BACKGROUND: Many health care providers do not provide adequate language access services for their patients who are limited English-speaking because they view the costs of these services as prohibitive. However, little is known about the costs they might bear because of unaddressed language barriers or the costs of providing language access services. OBJECTIVE: To investigate how language barriers and the provision of enhanced interpreter services impact the costs of a hospital stay. DESIGN: Prospective intervention study. SETTING: Public hospital inpatient medicine service. PARTICIPANTS: Three hundred twenty-three adult inpatients: 124 Spanish-speakers whose physicians had access to the enhanced interpreter intervention, 99 Spanish-speakers whose physicians only had access to usual interpreter services, and 100 English-speakers matched to Spanish-speaking participants on age, gender, and admission firm. MEASUREMENTS: Patient satisfaction, hospital length of stay, number of inpatient consultations and radiology tests conducted in the hospital, adherence with follow-up appointments, use of emergency department (ED) services and hospitalizations in the 3 months after discharge, and the costs associated with provision of the intervention and any resulting change in health care utilization. RESULTS: The enhanced interpreter service intervention did not significantly impact any of the measured outcomes or their associated costs. The cost of the enhanced interpreter service was $234 per Spanish-speaking intervention patient and represented 1.5% of the average hospital cost. Having a Spanish-speaking attending physician significantly increased Spanish-speaking patient satisfaction with physician, overall hospital experience, and reduced ED visits, thereby reducing costs by $92 per Spanish-speaking patient over the study period. CONCLUSION: The enhanced interpreter service intervention did not significantly increase or decrease hospital costs. Physician-patient language concordance reduced return ED visit and costs. Health care providers need to examine all the cost implications of different language access services before they deem them too costly.

Parental language and asthma among urban Hispanic children.

BACKGROUND: Many Hispanics in the United States have limited English proficiency and prefer communicating in Spanish. Language barriers are known to adversely affect health care quality and outcomes. OBJECTIVE: We explored the relationship between parent language preference in a Hispanic population and the likelihood that a child with symptoms receives a diagnosis of asthma. METHODS: We conducted a school-based survey in 105 Chicago public and Catholic schools. Our sample included 14,177 Hispanic children 6 to 12 years of age with a parent who completed an asthma survey. Outcomes of diagnosed asthma and possible asthma (asthma symptoms without diagnosis) were assessed by using the Brief Pediatric Asthma Screen Plus instrument. RESULTS: Overall, 12.0% of children had diagnosed asthma, and 12.7% had possible asthma. Parents of children at risk who completed the survey in English reported higher rates of asthma diagnosis compared with parents who completed it in Spanish (55.2% vs 36.3%, P < .001). Predictors of asthma diagnosis were child sex, parental language preference, parental asthma status, and other household members with asthma. CONCLUSIONS: Parental language preference might be an important characteristic associated with childhood asthma diagnosis. Whether language itself is the key factor or the fact that language is a surrogate for other attributes of acculturation needs to be explored. CLINICAL IMPLICATIONS: Our findings suggest that estimates of asthma among Hispanic schoolchildren might be low because of underdiagnosis among children whose parents prefer communicating in Spanish.

Asthma burden in a citywide, diverse sample of elementary schoolchildren in Chicago.

OBJECTIVE: The purposes of this study are to describe and develop preliminary models of the burden of diagnosed asthma and symptoms of possible undiagnosed asthma in a large, citywide, ethnically and socioeconomically diverse sample of Chicago elementary schoolchildren. We hypothesized that considering possible asthma would give a more complete picture of race/ethnic disparities in pediatric asthma. METHODS: We studied 35,583 students aged 6 to 12 years attending Chicago Public and Archdiocese elementary schools for the Chicago Initiative to Raise Asthma Health Equity (CHIRAH) study. The full enrollments of 105 schools were surveyed for asthma and possible undiagnosed asthma by the Brief Pediatric Asthma Screen Plus (BPAS+) respiratory symptoms. The child had to be 6 to 12 years old, the valid age range for the BPAS+. Questionnaires included the BPAS+, basic demographic information, and household asthma information; they were sent home with each schoolchild for completion by the parent and returned to school for collection and scoring. RESULTS: Overall, 13.9% of students had diagnosed asthma. For children aged 6 to 12 years, rates of diagnosed asthma varied from 13.1% to 14.5%, whereas the rates of possible undiagnosed asthma varied from 14.8% to 10.9%. The rate of diagnosed asthma was 21.2% for African Americans, 9.7% for whites, 11.8% for Hispanics, with similar rates of possible undiagnosed asthma. By multinomial logistic regression, African Americans were more than twice as likely and Hispanics were 1.57 times more likely than whites to have diagnosed asthma at all school district income levels and controlling for other household members with asthma, type of school, age of the child, gender, and language preference. The odds of African Americans being diagnosed with asthma rather than having possible asthma were 76% higher and for Hispanics were 46% higher compared with whites, at all school district income levels and controlling for other household members with asthma, type of school, age of the child, gender, and language preference. CONCLUSIONS: Our study confirms national disparities in diagnosed asthma by race/ethnicity. Respiratory symptoms consistent with possible undiagnosed asthma increase the total potential burden of asthma overall to more than one-quarter of the school enrollees. Among students with respiratory symptoms, African Americans, Hispanics (controlling for language), and families where another person has asthma are more likely to have diagnosed rather than possible asthma. Improved knowledge about asthma, recognition of symptoms, and access to high-quality care are necessary to ascertain how much of the possible undiagnosed asthma represents additional cases of asthma requiring treatment.
