RESUMO

BACKGROUND: Patients with advanced heart failure (AHF) are extensively evaluated before heart transplantation or left ventricular assist device (LVAD) eligibility. Patients are assessed for medical need and psychosocial or economic factors that may affect success post-treatment. For patients to be evaluated, however, they first must be referred. This study investigated social and economic factors affecting AHF referral, specialist visits, or treatment. METHODS: Patients with heart failure (n = 24,258) were reviewed at one large hospital system over 4 years. Independent variables age, sex, marital status, race/ethnicity, preferred language, smoking, and insurance status were assessed for the outcomes of referral, clinic visit, and treatment by Chi-square and ANOVA. In-house and 1-year mortality were evaluated by logistic regression, and time-to-event was assessed by the Cox proportional hazards model. RESULTS: Younger (HR 0.934, 95% CI 0.925-0.943), male (HR 2.216, 95% CI 1.544-3.181), and publicly insured (HR 1.298 [95% CI 1.038, 1.623]) patients were more likely to be referred, while unmarried (HR 0.665, 95% CI 0.488-0.905) and smoking (HR 0.549, 95% CI 0.389-0.776) patients had fewer referrals. Younger, married, and nonsmoking patients were more likely to have a clinic visit. Younger age, White race, and Hispanic/Latino ethnicity were associated with receiving a heart transplant, and LVAD recipients were more likely Hispanic/Latino ethnicity. Advanced age, Hispanic/Latino ethnicity, and smoking were associated with 1-year mortality after heart failure diagnosis. CONCLUSIONS: Disparities in access exist before evaluation for AHF therapies. Improving access at the levels of referral and evaluation is a necessary step toward achieving equity in organ allocation.

RESUMO

To develop and validate a brief, structured, behavioral health module for use by local public health practitioners to rapidly assess behavioral health needs in disaster settings. Data were collected through in-person, telephone, and web-based interviews of 101 individuals affected by Hurricanes Katrina (n = 44) and Sandy (n = 57) in New Orleans and New Jersey in April and May 2018, respectively. Questions included in the core module were selected based on convergent validity, internal consistency reliability, test-retest reliability across administration modes, principal component analysis (PCA), question comprehension, efficiency, accessibility, and use in population-based surveys. Almost all scales showed excellent internal consistency reliability (Cronbach's alpha, 0.79-0.92), convergent validity (r > 0.61), and test-retest reliability (in-person vs. telephone, intra-class coefficient, ICC, 0.75-1.00; in-person vs. web-based ICC, 0.73-0.97). PCA of the behavioral health scales yielded two components to include in the module-mental health and substance use. The core module has 26 questions-including self-reported general health (1 question); symptoms of posttraumatic stress disorder, depression, and anxiety (Primary Care PTSD Screen, Patient Health Questionnaire-4; 8 questions); drinking and other substance use (Alcohol Use Disorders Identification Test-Concise, AUDIT-C; Drug Abuse Screening Test, DAST-10; stand-alone question regarding increased substance use since disaster; 14 questions); prior mental health conditions, treatment, and treatment disruption (3 questions)-and can be administered in 5-10 minutes through any mode. This flexible module allows practitioners to quickly evaluate behavioral health needs, effectively allocate resources, and appropriately target interventions to help promote recovery of disaster-affected communities.

RESUMO

In 2015, more than 27 million people in the United States reported that they currently used illicit drugs or misused prescription drugs, and more than 66 million reported binge drinking during the previous month. Data from public health surveillance systems on drug and alcohol abuse are crucial for developing and evaluating interventions to prevent and control such behavior. However, public health surveillance for behavioral health in the United States has been hindered by organizational issues and other factors. For example, existing guidelines for surveillance evaluation do not distinguish between data systems that characterize behavioral health problems and those that assess other public health problems (eg, infectious diseases). To address this gap in behavioral health surveillance, we present a revised framework for evaluating behavioral health surveillance systems. This system framework builds on published frameworks and incorporates additional attributes (informatics capabilities and population coverage) that we deemed necessary for evaluating behavioral health-related surveillance. This revised surveillance evaluation framework can support ongoing improvements to behavioral health surveillance systems and ensure their continued usefulness for detecting, preventing, and managing behavioral health problems.

RESUMO

Evidence-based programs for prevention and intervention in substance abuse are increasing. Community needs assessments and health rankings provide descriptions of local behavioral health needs but do not provide public health practitioners and policy makers with guidelines on the number of programs, health care practitioners, or interventions needed in the local substance abuse care system. This article presents a new framework for measuring and assessing the substance abuse care system in a community. The assessment can inform resource allocation across the continuum of care to more equitably and efficiently distribute interventions and care. We conducted 2 literature reviews and synthesized our findings to create a community assessment methodology and needs calculator, CAST (calculating for an adequate system tool). We reviewed 212 articles to produce an inventory of community and social correlates of behavioral health, components of a substance abuse care system, and numerical values for guidelines for estimating community needs. CAST produces community-specific assessments of the capacity of the components of a community substance abuse care system. CAST generates recommendations by the application of social and community determinants of health as risk coefficients to each estimate of component need. CAST can assist public health practitioners in evaluation and improvement of the capacity of community-based, substance abuse care systems. By using recommendations for component needs across the continuum of care, community leaders can use CAST to prioritize resource allocation more effectively and efficiently.

RESUMO

PROBLEM/CONDITION: In the United States, marijuana is the most commonly used illicit drug. In 2013, 7.5% (19.8 million) of the U.S. population aged ≥12 years reported using marijuana during the preceding month. Because of certain state-level policies that have legalized marijuana for medical or recreational use, population-based data on marijuana use and other related indicators are needed to help monitor behavioral health changes in the United States. PERIOD COVERED: 2002-2014. DESCRIPTION OF SYSTEM: The National Survey on Drug Use and Health (NSDUH) is a national- and state-level survey of a representative sample of the civilian, noninstitutionalized U.S. population aged ≥12 years. NSDUH collects information about the use of illicit drugs, alcohol, and tobacco; initiation of substance use; frequency of substance use; substance dependence and abuse; perception of substance harm risk or no risk; and other related behavioral health indicators. This report describes national trends for selected marijuana use and related indicators, including prevalence of marijuana use; initiation; perception of harm risk, approval, and attitudes; perception of availability and mode of acquisition; dependence and abuse; and perception of legal penalty for marijuana possession. RESULTS: In 2014, a total of 2.5 million persons aged ≥12 years had used marijuana for the first time during the preceding 12 months, an average of approximately 7,000 new users each day. During 2002-2014, the prevalence of marijuana use during the past month, past year, and daily or almost daily increased among persons aged ≥18 years, but not among those aged 12-17 years. Among persons aged ≥12 years, the prevalence of perceived great risk from smoking marijuana once or twice a week and once a month decreased and the prevalence of perceived no risk increased. The prevalence of past year marijuana dependence and abuse decreased, except among persons aged ≥26 years. Among persons aged ≥12 years, the percentage reporting that marijuana was fairly easy or very easy to obtain increased. The percentage of persons aged ≥12 reporting the mode of acquisition of marijuana was buying it and growing it increased versus getting it for free and sharing it. The percentage of persons aged ≥12 years reporting that the perceived maximum legal penalty for the possession of an ounce or less of marijuana in their state is a fine and no penalty increased versus probation, community service, possible prison sentence, and mandatory prison sentence. INTERPRETATION: Since 2002, marijuana use in the United States has increased among persons aged ≥18 years, but not among those aged 12-17 years. A decrease in the perception of great risk from smoking marijuana combined with increases in the perception of availability (i.e., fairly easy or very easy to obtain marijuana) and fewer punitive legal penalties (e.g., no penalty) for the possession of marijuana for personal use might play a role in increased use among adults. PUBLIC HEALTH ACTION: National- and state-level data can help federal, state, and local public health officials develop targeted prevention activities to reduce youth initiation of marijuana use, prevent marijuana dependence and abuse, and prevent adverse health effects. As state-level laws on medical and recreational marijuana use change, modifications might be needed to national- and state-level surveys and more timely and comprehensive surveillance systems might be necessary to provide these data. Marijuana use in younger age groups is a particular public health concern, and changing the perception of harm risk from smoking marijuana is needed.

RESUMO

Motor vehicle accidents are the leading cause of death among youths and young adults aged 16-25 years in the United States (1). The prevalence of drinking and driving among high school students aged 16-19 years has declined by 54%, from 22.3% in 1991 to 10.3% in 2011 (2). However, the prevalence of weekend nighttime driving under the influence of marijuana (based on biochemical assays) among drivers aged ≥16 years has increased by 48%, from 8.6% in 2007 to 12.6% in 2013-2014 (3). Use of marijuana alone and in combination with alcohol has been shown to impair driving abilities (4-9). This report provides the most recent self-reported national estimates of driving under the influence of alcohol, marijuana, and alcohol and marijuana combined among persons aged 16-25 years, using data from the Substance Abuse and Mental Health Services Administration (SAMHSA) National Survey on Drug Use and Health (NSDUH) from 2002-2014. Prevalence data on driving under the influence of both substances were examined for two age groups (16-20 years and 21-25 years) and by sex and race/ethnicity. During 2002-2014, the prevalence of driving under the influence of alcohol alone significantly declined by 59% among persons aged 16-20 years (from 16.2% in 2002 to 6.6% in 2014; p<0.001) and 38% among persons 21-25 years (from 29.1% in 2002 to 18.1% in 2014; p<0.001). In addition, the prevalence of driving under the influence of alcohol and marijuana combined significantly declined by 39%, from 2.3% in 2002 to 1.4% in 2014 (p<0.001) among persons aged 16-20 years and from 3.1% in 2002 to 1.9% in 2014 (p<0.001) among persons aged 21-25 years. The prevalence of driving under the influence of marijuana alone declined 18%, from 3.8% in 2002 to 3.1% in 2014 (p = 0.05) only among persons aged 16-20 years. Effective public safety interventions,* such as minimum legal drinking age laws, prohibition of driving with any alcohol level >0 for persons aged <21 years, targeted mass media campaigns, roadside testing (e.g., sobriety checkpoints), and graduated driver licensing programs (10) have contributed to the decline in driving under the influence of alcohol in this population. These or similar interventions might be useful to prevent driving under the influence of other substances, such as marijuana alone or combined with other substances.

RESUMO

BACKGROUND: Since 2004, the US President's Emergency Plan for AIDS Relief (PEPFAR) has supported the tremendous scale-up of HIV prevention, care and treatment services, primarily in sub-Saharan Africa. We evaluate the impact of antiretroviral treatment (ART), prevention of mother-to-child transmission (PMTCT) and voluntary medical male circumcision (VMMC) programmes on survival, mortality, new infections and the number of orphans from 2004 to 2013 in 16 PEPFAR countries in Africa. METHODS: PEPFAR indicators tracking the number of persons receiving ART for their own health, ART regimens for PMTCT and biomedical prevention of HIV through VMMC were collected across 16 PEPFAR countries. To estimate the impact of PEPFAR programmes for ART, PMTCT and VMMC, we compared the current scenario of PEPFAR-supported interventions to a counterfactual scenario without PEPFAR, and assessed the number of life years gained (LYG), number of orphans averted and HIV infections averted. Mathematical modelling was conducted using the SPECTRUM modelling suite V.5.03. RESULTS: From 2004 to 2013, PEPFAR programmes provided support for a cumulative number of 24 565 127 adults and children on ART, 4 154 878 medical male circumcisions, and ART for PMTCT among 4 154 478 pregnant women in 16 PEPFAR countries. Based on findings from the model, these efforts have helped avert 2.9 million HIV infections in the same period. During 2004-2013, PEPFAR ART programmes alone helped avert almost 9 million orphans in 16 PEPFAR countries and resulted in 11.6 million LYG. CONCLUSIONS: Modelling results suggest that the rapid scale-up of PEPFAR-funded ART, PMTCT and VMMC programmes in Africa during 2004-2013 led to substantially fewer new HIV infections and orphaned children during that time and longer lives among people living with HIV. Our estimates do not account for the impact of the PEPFAR-funded non-biomedical interventions such as behavioural and structural interventions included in the comprehensive HIV prevention, care and treatment strategy used by PEPFAR countries. Therefore, the number of HIV infections and orphans averted and LYG may be underestimated by these models.

RESUMO

The history of the HIV epidemic and the response to the epidemic is fundamentally a history of an emergency response to a global crisis. Trends and projections from initially available data were instrumental in establishing the President's Emergency Plan for AIDS Relief (PEPFAR) and in determining the direction of the program. Additionally, PEPFAR was built on data and the potential impact of interventions, and required the constant monitoring of the epidemic to report on the progress of the program. The response to the HIV epidemic saw the development of international guidelines and recommendations for data collection and epidemiological modeling. Although it is true that the urgency of the response often meant that data from data-poor countries suffered from incompleteness and bias, fortunately, as the response matured, the quality of the data and the infrastructure supporting data collection also matured. PEPFAR investments in surveillance and surveys were and remain critical for responding to the epidemic. The future of the response is reflected in growing country capacities to collect valid and reliable data, and using those data for decision making.

RESUMO

Estimating sizes of hidden or hard-to-reach populations is an important problem in public health. For example, estimates of the sizes of populations at highest risk for HIV and AIDS are needed for designing, evaluating and allocating funding for treatment and prevention programmes. A promising approach to size estimation, relatively new to public health, is the network scale-up method (NSUM), involving two steps: estimating the personal network size of the members of a random sample of a total population and, with this information, estimating the number of members of a hidden subpopulation of the total population. We describe the method, including two approaches to estimating personal network sizes (summation and known population). We discuss the strengths and weaknesses of each approach and provide examples of international applications of the NSUM in public health. We conclude with recommendations for future research and evaluation.

RESUMO

BACKGROUND: Since 2003, the Global Fund has supported the scale-up of HIV/AIDS, tuberculosis and malaria control in low- and middle-income countries. This paper presents and discusses a methodology for estimating the lives saved through selected service deliveries reported to the Global Fund. METHODS: Global Fund-supported programs reported, by end-2007, 1.4 million HIV-infected persons on antiretroviral treatment (ARV), 3.3 million new smear-positive tuberculosis cases detected in DOTS (directly observed TB treatment, short course) programs, and 46 million insecticide-treated mosquito nets (ITNs) delivered. We estimated the corresponding lives saved using adaptations of existing epidemiological estimation models. RESULTS: By end-2007, an estimated 681,000 lives (95% uncertainty range 619,000-774,000) were saved and 1,097,000 (993,000-1,249,000) life-years gained by ARV. DOTS treatment would have saved 1.63 million lives (1.09-2.17 million) when compared against no treatment, or 408,000 lives (265,000-551,000) when compared against non-DOTS treatment. ITN distributions in countries with stable endemic falciparum malaria were estimated to have achieved protection from malaria for 26 million of child-years at risk cumulatively, resulting in 130,000 (27,000-232,000) under-5 deaths prevented. CONCLUSIONS: These results illustrate the scale of mortality effects that supported programs may have achieved in recent years, despite margins of uncertainty and covering only selected intervention components. Evidence-based evaluation of disease impact of the programs supported by the Global Fund with international and in-country partners must be strengthened using population-level data on intervention coverage and demographic outcomes, information on quality of services, and trends in disease burdens recorded in national health information systems.

RESUMO

OBJECTIVES: The 2001 Declaration of Commitment from the United Nations General Assembly Special Session on HIV/AIDS (UNGASS) set the prevention of HIV infection among injecting drug users (IDUs) as an important priority in the global fight against HIV/AIDS. This article examines data gathered to monitor the fulfillment of this commitment in low-income and middle-income countries (LMICs) where resources to develop an effective response to HIV are limited and where injecting drug use is reported to occur in 99 (of 147) countries, home to 75% of the estimated 15.9 million global IDU population. METHODS: Data relating to injecting drug use submitted by LMICs to the Joint United Nations Programme on HIV/AIDS (UNAIDS) in the 2008 reporting round for monitoring the Declaration of Commitment on HIV/AIDS were reviewed. The quality of the data reported was assessed and country data were aggregated and compared to determine progress in HIV prevention efforts. For each indicator, the mean value weighted for the size of each country's IDU population was determined; regional estimates were also made. RESULTS: Reporting was inconsistent between countries. Forty percent of LMIC (40/99), where injecting occurs, reported data for 1 or more of the 5 indicators pertinent to HIV prevention among IDUs. Many of the data reported were excluded from this analysis because the indicators used by countries were not consistent with those defined by UNAIDS Monitoring and Evaluation Reference Group and could not be compared. Data from 32 of 99 countries met our inclusion criteria. These 32 countries account for approximately two-thirds (68%) of the total estimated IDU population in all LMICs.The IDU population weighted means are as follows: 36% of IDUs tested for HIV in the last year; 26% of IDUs reached with HIV prevention programs in the last year; 45% of IDUs with correct HIV prevention knowledge; 37% of IDUs used a condom at last sexual intercourse; and 63% of IDUs used a clean syringe at last injection. Marked variance was observed in the data reported between different regions. CONCLUSIONS: Data from the 2008 United Nations General Assembly Special Session reporting round provide a baseline against which future progress might be measured. The data indicate a wide variation in HIV service coverage for IDUs and a wide divergence in HIV knowledge and risk behaviors among IDUs in different countries. Countries should be encouraged and assisted in monitoring and reporting on HIV prevention for IDUs.

RESUMO

BACKGROUND: HIV prevalence data suggest that men who have sex with men (MSM) in low-income and middle-income countries (LMIC) are at increased risk of HIV. The aim of this article is to present global estimates on key HIV prevention needs and responses among MSM in LMIC. METHODS: Data on HIV testing, HIV prevention coverage, HIV knowledge and condom use among MSM were derived from UNGASS country progress reports submitted in 2008. Eligible country estimates were used to calculate global and regional estimates, weighted for the size of MSM populations. RESULTS: Of 147 LMIC, 45% reported at least 1 indicator that reflects the HIV prevention needs and responses in MSM. Global weighted estimates indicate that on average 31% of MSM in LMIC were tested for HIV; 33% were reached by HIV prevention programs; 44% had correct HIV knowledge; and 54% used condoms the last time they had anal sex with a man. CONCLUSIONS: The 2008 UNGASS country reports represent the largest harmonized data set to date of HIV prevention needs and responses among MSM in LMIC. Although reporting is incomplete and does not always conform to requirements, findings confirm that, in many LMIC, HIV prevention responses in MSM need substantial strengthening.

RESUMO

OBJECTIVES: To investigate epidemiological patterns and trends of HIV infection and sexual behaviour among young people aged 15-24 years in the nine countries in southern Africa most affected by the HIV epidemic. METHODS: Data on HIV prevalence among young people in the general population were obtained from national population-based surveys conducted between 2000 and 2007, whereas data on sexual behaviour were obtained from repeat surveys between 1994 and 2007. Linear or exponential regression was used to analyse HIV prevalence trends among young women attending antenatal clinics in recent years. RESULTS: Patterns of HIV infection among young people are similar across the countries included in this analysis. The prevalence of HIV increases after the age of 15 years, more rapidly among women than among men, reaching a peak among women in their twenties and men in their thirties. Between 2000 and 2007 the prevalence of HIV among antenatal clinic attendees was constant in Mozambique and South Africa and declining in Lesotho, Namibia, Swaziland, Zambia, Botswana, Malawi and Zimbabwe, but only reached statistical significance (P < 0.05) in the last three. Changes towards safer sexual behaviour were observed over time among young men and women in the general population in this region. CONCLUSION: Sexual behaviour changes among young people are encouraging and are associated with declines in HIV prevalence among young antenatal clinic attendees over time. More research is needed to understand the recent changes and the very high prevalence among young women in this region. Interventions aimed at reducing risky behaviour need to be supported and expanded while incorporating new approaches to prevention.

RESUMO

OBJECTIVES: We measured the prevalence of hepatitis B virus (HBV) immunization and HBV infection among men aged 23 to 29 years who have sex with men. METHODS: We analyzed data from 2834 men who have sex with men in 6 US metropolitan areas. Participants were interviewed and tested for serologic markers of immunization and HBV infection in 1998 through 2000. RESULTS: Immunization prevalence was 17.2%; coverage was 21.0% among participants with private physicians or health maintenance organizations and 12.6% among those with no source of health care. Overall, 20.6% had markers of HBV infection, ranging from 13.7% among the youngest to 31.0% among the oldest participants. Among those susceptible to HBV, 93.5% had regular sources of health care, had been tested for HIV, or had been treated for a sexually transmitted disease. CONCLUSIONS: Although many young men who have sex with men have access to health care, most are not immunized against HBV. To reduce morbidity from HBV in this population, providers of health care, including sexually transmitted disease and HIV prevention services, should provide vaccinations or referrals for vaccination.

RESUMO

We conducted an anonymous cross-sectional seroprevalence study of a population with a low frequency of injection drug use to determine whether persons with a history of cosmetic procedures, such as tattooing and body piercing, or intranasal drug use were at increased risk for hepatitis C virus (HCV) or hepatitis B virus (HBV) infection. Students 18 years and older from eight college campuses in Houston, Texas, were invited to participate in the study. Of the 7,960 who completed a self-administered questionnaire and provided a blood sample, 5,282 U.S.- or Canadian-born participants were analyzed. Their median age was 21, 62% were female, 42% were white, 26% black, 22% Hispanic, and 10% Asian or other. Two percent reported injection drug use, 13.7% intranasal drug use, 21.2% body piercings, and 25.2% tattoos. The overall prevalence of HCV infection was 0.9% and of HBV infection was 5.2%. Higher HCV prevalence was independently associated with increasing age (odds ratio [OR] per year = 1.11; 95% confidence interval [CI] = 1.08-1.14), history of injection drug use (OR = 18.24; 95% CI = 7.74-42.92), blood transfusion before 1991 (OR = 3.21; 95% CI = 1.02-10.12), and incarceration (OR = 3.48; 95% CI = 1.45-8.37). Among 5,066 students who denied injecting drugs, HCV prevalence was 0.8% in those who reported intranasal drug use and 0.6% each in those who reported tattoos and those who reported body piercing. Increased HBV prevalence was associated with high-risk sexual behaviors and black or Asian race. In conclusion, there was no increased risk for HCV or HBV infection in low-risk adults based solely on history of cosmetic procedures or snorting drugs. However, proper infection control practices for cosmetic procedures should be followed, illegal drug use discouraged, and hepatitis B vaccination provided to adolescents and sexually active adults.

RESUMO

OBJECTIVE: To assess the prevalence and correlates of hepatitis C virus infection in a sample of detained adolescents. DESIGN/SETTING/PARTICIPANTS: Cross-sectional prevalence study with 10- to 18-year-old adolescents who were consecutively admitted to a juvenile detention center in San Antonio, Tex. MAIN OUTCOME MEASURES: The prevalence of hepatitis C virus infection and associated risk factors. RESULTS: Of the 1002 participants, 75% were Hispanic and the mean age was 15 years. Twenty adolescents had laboratory data consistent with hepatitis C virus infection, giving an overall prevalence of 2.0% (95% confidence interval, 1.2-3.1). All adolescents infected with hepatitis C virus were Hispanic (13 boys and 7 girls). Although a high proportion of the participants reported having had intranasal drug use (55.6%), tattooing (50.5%), or body piercing (25.3%), the only factor significantly associated with hepatitis C virus infection was having a history of injection drug use. Injection drug use was reported by 5.3% of the participants but by 95% (19/20) of those infected with the hepatitis C virus. CONCLUSIONS: This study indicates that injection drug use was linked with the majority of hepatitis C virus infections in this population of detained adolescents, similar to findings in adults. These adolescents reported a high frequency of other behaviors that could potentially pose a risk for contracting bloodborne infections. Effective prevention and awareness programs in a detention setting need to be comprehensive and include screening, hepatitis A and B immunizations, and risk-reduction counseling.

RESUMO

This report consolidates previous recommendations and adds new ones for preventing and controlling infections with hepatitis viruses in correctional settings. These recommendations provide guidelines for juvenile and adult correctional systems regarding 1) identification and investigation of acute viral hepatitis; 2) preexposure and postexposure immunization for hepatitis A and hepatitis B; 3) prevention of hepatitis C virus infection and its consequences; 4) health education; and 5) release planning. Implementation of these recommendations can reduce transmission of infections with hepatitis viruses among adults at risk in both correctional facilities and the outside community. These recommendations were developed after consultation with other federal agencies and specialists in the fields of corrections, correctional health care, and public health at a meeting in Atlanta, March 5-7, 2001. This report can serve as a resource for those involved in planning and implementing health-care programs for incarcerated persons.
