How different governance models may impact physician-hospital alignment.

BACKGROUND: Hospitals utilize three ideal type models for governing relationships with their physicians: the traditional medical staff, strategic alliances, and employment. Little is known about how these models impact physician alignment. PURPOSE: The study compares the level of physician-hospital alignment across the three models. APPROACH: We used survey data from 1,895 physicians in all three models across 34 hospitals in eight systems to measure several dimensions of alignment. We used logistic equations to predict survey nonresponse and differential physician selection into the alliance and employment models. Controlling for these selection effects, we then used multiple regression to estimate the effects of alliance and employment models on alignment. RESULTS: Physicians in employment models express greater alignment with their hospital on several dimensions, compared to physicians in alliances and the traditional medical staff. There were no differences in physician alignment between the latter two models. CONCLUSIONS: Employment models promote greater alignment on some (but not all) dimensions, controlling for physician selection. The impact of employment on alignment is not large, however. PRACTICE IMPLICATIONS: Hospitals and accountable care organizations that rely on employment may achieve higher physician alignment compared to the other two models. It is not clear that the gain in alignment is worth the cost of employment. Given the small impact of employment on alignment, it is also clear that they are not identical. Hospitals may need to go beyond structural models of integration to achieve alignment with their physicians.

A pilot replication of QUIT, a randomized controlled trial of a brief intervention for reducing risky drug use, among Latino primary care patients.

BACKGROUND: QUIT is the only primary care-based brief intervention that has previously shown efficacy for reducing risky drug use in the United States (Gelberg et al., 2015). This pilot study replicated the QUIT protocol in one of the five original QUIT clinics primarily serving Latinos. DESIGN: Single-blind, two-arm, randomized controlled trial of patients enrolled from March-October 2013 with 3-month follow-up. SETTING: Primary care waiting room of a federally qualified health center (FQHC) in East Los Angeles. PARTICIPANTS: Adult patients with risky drug use (4-26 on the computerized WHO ASSIST): 65 patients (32 intervention, 33 control); 51 (78%) completed follow-up; mean age 30.8 years; 59% male; 94% Latino. INTERVENTIONS AND MEASURES: Intervention patients received: 1) brief (typically 3-4 minutes) clinician advice to quit/reduce their risky drug use, 2) video doctor message reinforcing the clinician's advice, 3) health education booklet, and 4) up to two 20-30 minute follow-up telephone drug use reduction coaching sessions. Control patients received usual care and cancer screening information. Primary outcome was reduction in number of days of drug use in past 30days of the highest scoring drug (HSD) on the baseline ASSIST, from baseline to 3-month follow-up. RESULTS: Controls reported unchanged HSD use between baseline and 3-month follow-up whereas Intervention patients reported reducing their use by 40% (p<0.001). In an intent-to-treat linear regression analysis, intervention patients reduced past month HSD use by 4.5 more days than controls (p<0.042, 95% CI: 0.2, 8.7). Similar significant results were found using a complete sample regression analysis: 5.2 days (p<0.03, 95% CI: 0.5, 9.9). Additionally, on logistic regression analysis of test results from 47 urine samples at follow-up, intervention patients were less likely than controls to test HSD positive (p<0.05; OR: 0.10, 95% CI: 0.01, 0.99). CONCLUSIONS: Findings support the efficacy of the QUIT brief intervention for reducing risky drug use.

Prevalence of Substance Use Among Patients of Community Health Centers in East Los Angeles and Tijuana.

BACKGROUND: Given the increased use of psychoactive substances on the United States-Mexico border, a binational study (Tijuana, Mexico-Los Angeles, USA) was conducted to identify the prevalence of substance use in primary care settings. OBJECTIVES: To compare the prevalence and characteristics of patients at risk for substance use disorders in Tijuana and East Los Angeles (LA) community clinics with special attention paid to drug use. METHODS: This was an observational, cross-sectional, analytical study, comparing substance use screening results from patients in Tijuana and LA. The settings were 2 community clinics in LA and 6 in Tijuana. Participants were 2,507 adult patients in LA and 2,890 in Tijuana eligible for WHO Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) screening during March-October 2013. Patients anonymously self-administered the WHO ASSIST on a tablet PC in the clinic waiting rooms. RESULTS: Of eligible patients, 96.4% completed the ASSIST in Tijuana and 88.7% in LA (mean 1.34 minutes and 4.20 minutes, respectively). The prevalence of patients with moderate-to-high substance use was higher in LA than Tijuana for each substance: drugs 19.4% vs. 5.7%, alcohol 15.2% vs. 6.5%, tobacco 20.4% vs. 16.2%. LA patients born in Mexico had 2x the odds and LA patients born in the United States had 6x the odds of being a moderate-to-high drug user compared to Tijuana patients born in Mexico. CONCLUSIONS: Moderate-to-high drug use is higher in LA than in Tijuana but rates are sufficiently high in both to suggest that screening for drug use (along with alcohol and tobacco use) should be integrated into routine primary care of community clinics in both cities.

Under-reporting of Risky Drug Use Among Primary Care Patients in Federally Qualified Health Centers.

OBJECTIVE: The Affordable Care Act encourages integration of behavioral health into primary care. We aim to estimate the level of under-reporting of drug use in federally qualified health centers (FQHCs) among self-reported risky drug users. METHODS: Adult patients in the waiting rooms of 4 FQHCs who self-reported risky drug use on the screening instrument World Health Organization's Alcohol, Smoking and Substance Involvement Screening Test (score 4-26), who participated in the "Quit Using Drugs Intervention Trial," submitted urine samples for drug testing. Under-reporters were defined as patients who denied use of a specific drug via questionnaire, but whose urine drug test was positive for that drug. Descriptive statistics, Pearson chi-square test, and logistic regression were used for analysis. RESULTS: Of the 192 eligible participants, 189 (96%) provided urine samples. Fifty-four samples were negative or indeterminate, yielding 135 participants with positive urine drug tests for this analysis: 6 tested positive for amphetamines, 18 opiates, 21 cocaine, 97 marijuana. Thirty patients (22%) under-reported drug use and 105 (78%) reported drug use accurately. Under-reporting by specific substances was: amphetamines 66%, opiates 45%, cocaine 14%, and marijuana 7%. Logistic regression revealed that under-reporting of any drug was associated with history of incarceration and older age (odds ratios 2.6 and 3.3, respectively; P < 0.05). CONCLUSIONS: Under-reporting of drug use is prevalent even among self-reported drug users in primary care patients of FQHCs (22%), but varied considerably based on the substance used. Further research is indicated to assess the extent of under-reporting among all primary care patients, regardless of their self-reported drug use status.

Diagnoses Treated in Ambulatory Care Among Homeless-Experienced Veterans: Does Supported Housing Matter?

PURPOSE: Little is known about how permanent supported housing influences ambulatory care received by homeless persons. To fill this gap, we compared diagnoses treated in VA Greater Los Angeles (VAGLA) ambulatory care between Veterans who are formerly homeless-now housed/case managed through VA Supported Housing ("VASH Veterans")-and currently homeless. METHODS: We performed secondary database analyses of homeless-experienced Veterans (n = 3631) with VAGLA ambulatory care use from October 1, 2010 to September 30, 2011. We compared diagnoses treated-adjusting for demographics and need characteristics in regression analyses-between VASH Veterans (n = 1904) and currently homeless Veterans (n = 1727). RESULTS: On average, considering 26 studied diagnoses, VASH (vs currently homeless) Veterans received care for more (P < .05) diagnoses (mean = 2.9/1.7). Adjusting for demographics and need characteristics, VASH Veterans were more likely (P < .05) than currently homeless Veterans to receive treatment for diagnoses across categories: chronic physical illness, acute physical illness, mental illness, and substance use disorders. Specifically, VASH Veterans had 2.5, 1.7, 2.1, and 1.8 times greater odds of receiving treatment for at least 2 condition in these categories, respectively. Among participants treated for chronic illnesses, adjusting for predisposing and need characteristics, VASH (vs currently homeless) Veterans were 9%, 8%, and 11% more likely to have 2 or more visits for chronic physical illnesses, mental illnesses, and substance use disorder, respectively. CONCLUSION: Among homeless-experienced Veterans, permanent supported housing may reduce disparities in the treatment of diagnoses commonly seen in ambulatory care.

Individual- and Neighborhood-Level Determinants of Fear of Violent Crime Among Adolescents.

Fear of violent crime is common among adolescents in urban settings; however, little is known about individual- and neighborhood-level determinants of fear. A generalized ordered logit model was used to analyze individual- and neighborhood-level variables among 2474 adolescents. Seeing violence significantly reduced the probability of feeling unafraid, as did higher levels of social disorder. The more block faces where police were visible, the higher the probability of feeling unafraid and lower the probability of feeling very afraid. Reducing fear could affect more people than just reducing crime. Fear-reduction strategies should target those most at risk of becoming fearful.

Clinicians' Beliefs and Practices Regarding Drug Use Care of Their Community Health Center Patients.

OBJECTIVES: Integration of behavioral health including substance use problems into primary care is an essential benefit that federally qualified health centers (FQHCs) will offer as part of the Affordable Care Act. This study explores FQHC primary care clinicians' beliefs and practices regarding illicit drug use assessment and treatment. METHODS: We administered a 10-minute questionnaire to 68 primary care clinicians of 5 FQHCs in Los Angeles. RESULTS: Clinicians expressed limited confidence in their ability to address patients' illicit drug use, scoring on average 3.31 on a 5-point Likert scale. Two thirds reported that they assess for drug use routinely "at every visit" and/or "at annual visits." When asked how often they counsel regarding drug use (on a 5-point Likert scale from "never" to "always"), the median response was 4 ("usually"). Regarding their perspectives on the best practical resource for addressing drug use in their clinics, 45.6% named primary care clinicians. A minority (29.4%) of clinicians had completed a clinical rotation dealing with substance use, and 27.2% reported receiving more than 10  hours of training regarding substance use problems. Having a substance use rotation was associated with greater confidence in drug use assessment and treatment (P < 0.01). More hours of substance use training was associated with greater confidence (P = 0.01) and routinely addressing substance use in their patients (P = 0.04). CONCLUSIONS: Although two thirds of the surveyed clinicians assess for drug use routinely, and on average, report that they usually address drug use, clinicians' confidence in substance use care seems to be suboptimal, but both confidence and routinely addressing substance use are associated with increased substance use education. Improving clinicians' training and integrating drug use care in FQHCs may improve confidence in substance use care and facilitate the Affordable Care Act's mandate to integrate behavioral health into routine FQHC primary care.

Project QUIT (Quit Using Drugs Intervention Trial): a randomized controlled trial of a primary care-based multi-component brief intervention to reduce risky drug use.

AIMS: To assess the effect of a multi-component primary care delivered brief intervention for reducing risky psychoactive drug use (RDU) among patients identified by screening. DESIGN: Multicenter single-blind two-arm randomized controlled trial of patients enrolled from February 2011 to November 2012 with 3-month follow-up. Randomization and allocation to trial group were computer-generated. SETTING: Primary care waiting rooms of five federally qualified health centers in Los Angeles County (LAC), USA. PARTICIPANTS: A total of 334 adult primary care patients (171 intervention; 163 control) with RDU scores (4-26) on the World Health Organization (WHO) Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) self-administered on tablet computers. 261 (78%) completed follow-up. Mean age was 41.7 years; 62.9% were male; 37.7% were Caucasian. INTERVENTION(S) AND MEASUREMENT: Intervention patients received brief (typically 3-4 minutes) clinician advice to quit/reduce their drug use reinforced by a video doctor message, health education booklet and up to two 20-30-minute follow-up telephone drug use coaching sessions. Controls received usual care and cancer screening information. Primary outcome was patient self-reported use of highest scoring drug (HSD) at follow-up. FINDINGS: Intervention and control patients reported equivalent baseline HSD use at 3-month follow-up. After adjustment for covariates, in the complete sample linear regression model, intervention patients used their HSD on 3.5 fewer days in the previous month relative to controls (P<0.001), and in the completed sample model, intervention patients used their HSD 2.2 fewer days than controls (P < 0.005). No compensatory increases in use of other measured substances were found. CONCLUSIONS: A primary-care based, clinician-delivered brief intervention with follow-up coaching calls may decrease risky psychoactive drug use.

Assessing the contribution of the dental care delivery system to oral health care disparities.

OBJECTIVES: Existing studies of disparities in access to oral health care for underserved populations often focus on supply measures such as number of dentists. This approach overlooks the importance of other aspects of the dental care delivery system, such as personal and practice characteristics of dentists, that determine the capacity to provide care. This study aims to assess the role of such characteristics in access to care of underserved populations. METHODS: We merged data from the 2003 California Health Interview Survey and a 2003 survey of California dentists in their Medical Study Service Areas (MSSAs). We examined the role of overall supply and other characteristics of dentists in income and racial/ethnic disparities in access, which was measured by annual dental visits and unmet need for dental care due to costs. RESULTS: We found that some characteristics of MSSAs, including higher proportions of dentists who were older, white, busy or overworked, and did not accept public insurance or discounted fees, inhibited access for low-income and minority populations. CONCLUSIONS: These findings highlight the importance of monitoring characteristics of dentists in addition to traditional measures of supply such as licensed-dentist-to-population ratios. The findings identify specific aspects of the delivery system such as dentists' participation in Medicaid, provision of discounted care, busyness, age, race/ethnicity, and gender that should be regularly monitored. These data will provide a better understanding of how the dental care delivery system is organized and how this knowledge can be used to develop more narrowly targeted policies to alleviate disparities.

Effect of a primary care based brief intervention trial among risky drug users on health-related quality of life.

BACKGROUND: Improvement in quality of life (QOL) is a long term goal of drug treatment. Although some brief interventions have been found to reduce illicit drug use, no trial among adult risky (moderate non-dependent) drug users has tested effects on health-related quality of life. METHODS: A single-blind randomized controlled trial of patients enrolled from February 2011 to November 2012 was conducted in waiting rooms of five federally qualified health centers. 413 adult primary care patients were identified as risky drug users using the WHO-ASSIST and 334 (81% response; 171 intervention, 163 control) consented to participate in the trial. Three-month follow-ups were completed by 261 patients (78%). Intervention patients received the QUIT intervention of brief clinician advice and up to two drug-use health telephone sessions. The control group received usual care and information on cancer screening. Outcomes were three-month changes in the Short Form Health Survey (SF-12) mental health component summary score (MCS) and physical health component summary score (PCS). RESULTS: The average treatment effect (ATE) was non-significant for MCS (0.2 points, p-value=0.87) and marginally significant for PCS (1.7 points, p-value=0.08). The average treatment effect on the treated (ATT) was 0.1 (p-value=0.93) for MCS and 1.9 (p-value=0.056) for PCS. The effect on PCS was stronger at higher (above median) baseline number of drug use days: ATE=2.7, p-value=0.04; ATT=3.21, p-value=0.02. CONCLUSIONS: The trial found a marginally significant effect on improvement in PCS, and significant and stronger effect on the SF-12 physical component among patients with greater frequency of initial drug use.

VA health service utilization for homeless and low-income Veterans: a spotlight on the VA Supportive Housing (VASH) program in greater Los Angeles.

BACKGROUND: The US Department of Housing and Urban Development (HUD)-VA Supportive Housing (VASH) program-the VA's Housing First effort-is central to efforts to end Veteran homelessness. Yet, little is known about health care utilization patterns associated with achieving HUD-VASH housing. OBJECTIVES: We compare health service utilization at the VA Greater Los Angeles among: (1) formerly homeless Veterans housed through HUD-VASH (HUD-VASH Veterans); (2) currently homeless Veterans; (3) housed, low-income Veterans not in HUD-VASH; and (4) housed, not low-income Veterans. RESEARCH DESIGN: We performed a secondary database analysis of Veterans (n=62,459) who received VA Greater Los Angeles care between October 1, 2010 and September 30, 2011. We described medical/surgical and mental health utilization [inpatient, outpatient, and emergency department (ED)]. We controlled for demographics, need, and primary care use in regression analyses of utilization data by housing and income status. RESULTS: HUD-VASH Veterans had more inpatient, outpatient, and ED use than currently homeless Veterans. Adjusting for demographics and need, HUD-VASH Veterans and the low-income housed Veterans had similar likelihoods of medical/surgical inpatient and outpatient utilization, compared with the housed, not low-income group. Adjusting first for demographics and need (model 1), then also for primary care use (model 2), HUD-VASH Veterans had the greatest decrease in incident rates of specialty medical/surgical, mental health, and ED care from models 1 to 2, becoming similar to the currently homeless, compared with the housed, not low-income group. CONCLUSIONS: Our findings suggest that currently homeless Veterans underuse health care relative to housed Veterans. HUD-VASH may address this disparity by providing housing and linkages to primary care.

Barriers to drug use behavior change among primary care patients in urban United States community health centers.

In 2011 and 2012, 147 patients in urban United States Community Health Centers who misused drugs, but did not meet criteria for drug dependence, received a brief intervention as part of a National Institute on Drug Abuse-funded clinical trial of a screening and brief intervention protocol. Potential study participants were identified using the World Health Organization (WHO) Alcohol, Smoking, and Substance Involvement Screening Test. Data gathered during brief interventions were analyzed using grounded theory strategies to identify barriers patients believed inhibited drug use behavior change. Numerous perceived barriers to drug use behavior change were identified. Study implications and limitations are discussed.

Serving homeless veterans in the VA Desert Pacific Healthcare Network: a needs assessment to inform quality improvement endeavors.

This report describes a needs assessment of VA programs for homeless Veterans in Southern California and Nevada, the geographic region with the most homeless Veterans in the nation. The assessment was formulated through key informant interviews. Current service provisions are discussed, along with salient unmet needs for this vulnerable population.

Chronic disease management for recently homeless veterans: a clinical practice improvement program to apply home telehealth technology to a vulnerable population.

BACKGROUND: Although vulnerable populations may benefit from in-home health information technologies (HIT) that promote disease self-management, there is a "digital divide" in which these groups are often unlikely to use such programs. We describe the early phases of applying and testing an existing Veterans Affairs (VA) HIT-care management program, Care Coordination Home Telehealth (CCHT), to recently homeless Veterans in the US Department of Housing and Urban Development-VA Supportive Housing (HUD-VASH) program. Peers were used to support patient participation. METHODS: CCHT uses in-home messaging devices to provide health education and daily questions about clinical indicators from chronic illness care guidelines, with patient responses reviewed by VHA nurses. Patients could also receive adjunctive peer support. We used medical record review, Veteran interviews, and staff surveys to "diagnose" barriers to CCHT use, assess program acceptability, explore the role of peer support, and inform future quality improvement. SUBJECTS: Fourteen eligible Veterans in HUD-VASH agreed to CCHT participation. Ten of these Veterans opted to have adjunctive peer support and the other 4 enrolled in CCHT usual care. RESULTS: Although barriers to enrollment/engagement must be addressed, this subset of Veterans in HUD-VASH was satisfied with CCHT. Most Veterans did not require support from peers to engage in CCHT but valued peer social assistance amidst the isolation felt in their scattered-site homes. CONCLUSIONS: HIT tools hold promise for in-home care management for recently housed Veterans. Patient-level barriers to enrollment must be addressed in the next steps of quality improvement, testing and evaluating peer-driven CCHT recruitment.

Personality-related factors as predictors of help-seeking for depression: a population-based study applying the Behavioral Model of Health Services Use.

BACKGROUND: Although the prevalence of mental disorders and the demand for mental health services are increasing, little is known about the impact of personality-related factors on help-seeking among depressive individuals. We, therefore, investigated the relationship between the "Big Five" personality traits, resilience, alexithymia, childhood neglect or abuse, and help-seeking among depressive individuals. METHODS: We used data from 354 persons with a diagnosis of major depression from the population-based cohort study of health in Pomerania within the theoretical framework of the Andersen Behavioral Model of Health Services Use. RESULTS: Using stepwise regression techniques, we found that older age, higher education, more perceived social support, presence of childhood abuse, higher levels of conscientiousness, lower levels of resilience, and more severe depression were associated with help-seeking for depression. In contrast, gender, extraversion, openness, agreeableness, neuroticism, and alexithymia did not significantly predict help-seeking. In addition, no evidence for gender-specific effects was observed. CONCLUSION: Personality-related predisposing factors are important predictors of help-seeking. The influence of resilience on help-seeking among depressed individuals merits further exploration.

HIV and STI risk behaviors, knowledge, and testing among female adult film performers as compared to other California women.

A cross-sectional structured online survey was self-administered to a convenience sample of current female adult film performers via the Internet; bivariate analyses compared HIV and other STI risk behaviors, knowledge, and testing in female adult performers to California Women's Health Survey respondents. 134 female adult film performers (mean age 27.8 years) were compared to the 1,773 female respondents (mean age 31.3 years) to the 2007 CWHS. Female performers initiated sex on average 3 years younger and had 6.8 more personal sexual partners in the prior year than other California women. The majority of performers reported HIV and Chlamydia testing (94 and 82%, respectively) in the prior 12 months. They more likely to use condoms consistently in their personal life than other California women (21 vs 17%), though this difference disappeared after controlling for other variables. Adult performers are routinely tested for HIV and Chlamydia, yet they have multiple sexual partners and use condoms inconsistently.

Race/ethnicity, parent-identified emotional difficulties, and mental health visits among California children.

Variability in mental health services utilization by race/ethnicity was evaluated with a Behavioral Model approach. Subjects were 17,705 children 5 to 11 years of age in the 2005, 2007, and 2009 California Health Interview Surveys. Parents identified minor emotional difficulties in 18.7% of these children (ranging from 14.8% in Asians to 24.4% in African Americans) and definite or severe difficulties in 7.4% (5.5% in Asians to 9.7% in "other race"). Overall, 7.6% of children had at least one mental health visit in the prior year (2.3% in Asians to 11.2% in African Americans). Parent-identified need was the most salient predictor of mental health visits for all racial/ethnic groups. Beyond need, no consistent patterns could be determined across racial/ethnic groups with regard to the relationship between contextual, predisposing, and enabling measures and mental health service utilization. Different factors operated for each racial/ethnic group, suggesting the need for studies to examine mental health need, mental health service use, and determinants by racial/ethnic subgroup. These findings suggest that a "one-size-fits-all approach" with regard to policies and practices aimed at reducing mental health disparities will not be effective for all racial/ethnic groups.

Prevalence, distribution, and correlates of hepatitis C virus infection among homeless adults in Los Angeles.

OBJECTIVE: We documented the prevalence, distribution, and correlates of hepatitis C virus (HCV) infection among urban homeless adults. METHODS: We sampled a community-based probability sample of 534 homeless adults from 41 shelters and meal programs in the Skid Row area of downtown Los Angeles, California. Participants were interviewed and tested for HCV, hepatitis B, and HIV. Outcomes included prevalence, distribution, and correlates of HCV infection; awareness of HCV positivity; and HCV counseling and treatment history. RESULTS: Overall, 26.7% of the sample tested HCV-positive and 4.0% tested HIV-positive. In logistic regression analysis, independent predictors of HCV infection for the total sample included older age, less education, prison history, and single- and multiple-drug injection. Among lifetime drug injectors, independent predictors of HCV infection included older age, prison history, and no history of intranasal cocaine use. Among reported non-injectors, predictors of HCV infection included older age, less education, use of non-injection drugs, and three or more tattoos. Sexual behaviors and snorting or smoking drugs had no independent relationship with HCV infection. Among HCV-infected adults, nearly half (46.1%) were unaware of their infection. CONCLUSIONS: Despite the high prevalence of HCV infection, nearly half of the cases were hidden and few had ever received any HCV-related treatment. While injection drug use was the strongest independent predictor, patterns of injection drug use, non-injection drug use, prison stays, and multiple tattoos were also independent predictors of HCV. Findings suggest that urgent interventions are needed to screen, counsel, and treat urban homeless adults for HCV infection.

Impact of hepatitis B and C infection on health services utilization in homeless adults: a test of the Gelberg-Andersen Behavioral Model for Vulnerable Populations.

OBJECTIVE: Homeless people have disproportionately high rates of viral hepatitis. The Gelberg-Andersen Behavioral Model for Vulnerable Populations (predisposing, enabling, and need variables) was expanded to predict prevalence and awareness of hepatitis B (HBV) or hepatitis C (HCV) infection, as well as health services utilization (HSU) among homeless adults using structural equation modeling. DESIGN: A population-based sample of 534 homeless adults in Los Angeles' "Skid Row" was interviewed and tested for HBV and HCV. MAIN OUTCOME MEASURES: Main outcome measures included HBV/HCV seropositivity, awareness of seropositivity, and HSU in the previous 12 months. RESULTS: Seropositivity (43%), usually unknown (72% of seropositives), was predicted by injection drug use, alcohol use, older age, and risky sexual behavior. No regular source of care, risky sexual behavior, less case management, and greater age predicted not knowing one's positive status. Health insurance, younger age, alcohol use, perceived bad health and more medical conditions predicted emergency room (ER) use; ER use was less likely among seropositives. Hospitalizations were predicted by more medical conditions and greater percentage of life homeless and were less frequent among African Americans and males. Ambulatory visits were predicted by a regular source of care, case management, more education and perceived bad health; they were less likely among seropositives. CONCLUSION: The Gelberg-Andersen Behavioral Model provided a useful guide for predicting HBV/HCV positivity as well as HSU in homeless adults. Most hepatitis-positives did not know their status and used health services less often than other homeless adults. More aggressive detection of hepatitis B and C among homeless adults is needed.

Comparison of the mental health of female adult film performers and other young women in California.

OBJECTIVE: This study compared self-reported mental health status and current depression of female adult film performers and other young women. METHODS: A cross-sectional structured online survey adapted from the California Women's Health Survey (CWHS) was self-administered to a convenience sample of 134 current female adult film performers via the Internet. Bivariate and multivariate analyses were used to compare data for these women with data for 1,773 women of similar ages who responded to the 2007 CWHS. Main outcome measures were self-reported mental health status, measured with the Behavioral Risk Factor Surveillance Survey core-instrument quality-of-life questions, and current depression, measured with the Patient Health Questionnaire-8. RESULTS: Performers reported a mean of 7.2 days of poor mental health in the past 30 days, compared with 4.8 days for CWHS respondents, and 33% met criteria for current depression, compared with 13% of CWHS respondents (p<.01). As children, the adult film performers were more likely to have been victims of forced sex (37% compared with 13% of CWHS respondents), to have lived in poverty (24% and 12%), and to have been placed in foster care (21% and 4%) (p<.01). In the past 12 months, 50% of the performers reported living in poverty and 34% reported experiencing domestic violence, compared with 36% and 6%, respectively, of CWHS respondents (p<.01). As adults, 27% had experienced forced sex, compared with 9% of CWHS respondents (p<.01). CONCLUSIONS: Female adult film performers have significantly worse mental health and higher rates of depression than other California women of similar ages.
