Predictors of perceived health status of tuberculosis-infected homeless

Health Related Quality of Life among TB Patients: Question Mark on Performance of TB DOTS in Pakistan

Due to long duration of treatment and use of several agents, tuberculosis can lead to poor health related quality of life among patients. Objective. The present study was designed to assess health related quality of life among pulmonary tuberculosis patients in Pakistan. Methodology. A descriptive cross-sectional study design was used. SF-36 was self-administered to a sample of 382 pulmonary tuberculosis patients receiving self-administered or directly observed types of treatment, in baseline, initial, or continuous phase of treatment. After data collection, data was cleaned, coded, and statistically analyzed using SPSS version 21.0. Results. The results of the current study highlighted a significant impact on several domains of HRQoL of pulmonary TB patients. Highest HRQoL scores had been observed for the domain of physical functioning (60.03, ±25.779) whereas lowest HRQoL scores were observed for the domain of general health (34.97, ±14.286) perceptions of TB patients followed by bodily pain (43.40, ±24.594). Conclusion. The results of the present study concluded that TB patients had poor HRQoL in spite of the new therapeutic strategies and free availability of medicines. The disease had a negative impact on HRQoL of TB patients across all domains.

High social anxiety and poor quality of life in patients with pulmonary tuberculosis

Pulmonary tuberculosis (PT) has been previously related with various psychosocial adverse consequences including stigmatization and social isolation.Social anxiety is a psychiatric condition that may be associated with social isolation and fear of social exclusion.To date no study has investigated social anxiety and its impact on quality of life (QoL) among patients with PT. Therefore, we aimed to determine the severity of social anxiety in a group of patients with PT.Among patients who were recently discharged from hospital with the diagnosis of PT 94 patients and 99 healthy control subjects who had similar demographical features have been included in the study. A psychiatrist interviewed all participants and a semistructured interview form, which was prepared by the authors, Liebowitz Social Anxiety Scale (LSAS), and Short Form-36 were administered to them.Patients with PT showed higher levels of performance avoidance and social avoidance than healthy control subjects. They reported lower QoL scores across all dimensions. Among patients women showed higher levels of LSAS subscale scores and total score. Fear of social exclusion was predicted by perceived illness severity and emotional role difficulty. On the other hand, perceived illness severity was predicted by fear of exclusion and sedimentation level.PT patients seem to experience higher levels of social anxiety and associated fear of social exclusion that add to their worse QoL during the earlier months of their disease. Among them fear of social exclusion is related with perceived illness severity.

Increasing hepatitis C knowledge among homeless adults: results of a community-based, interdisciplinary intervention

Homeless adults have high rates of hepatitis C virus infection (HCV) and low levels of HCV knowledge. This study reports results of an interdisciplinary, community-based intervention using stakeholder cooperation, case management, risk factor identification, and modification of dysfunctional psychosocial factors to increase HCV knowledge among homeless adults (N = 747). Data are from a randomized quasi-experimental study, with the major goal of evaluating the effectiveness of a Nurse Case Managed Intervention compared to a Standard Intervention, encouraging completion of a three-series hepatitis A/hepatitis B vaccination program. Increased HCV knowledge was measured with an 18-item questionnaire discerning risk factors for HCV and common misconceptions about individuals with HCV. A significant increase in HCV knowledge resulted regardless of intervention format. Receiving the Nurse Case Managed Intervention predicted greatest gain in HCV knowledge (p < 0.000). Successfully engaging key stakeholders, outreach workers, community organizations, and homeless people themselves proved most efficacious in increasing HCV knowledge.

Counting the homeless: a previously incalculable tuberculosis risk and its social determinants

Tuberculosis (TB) surveillance among the homeless is not supported by the political will necessary for TB elimination. We merged the first stakeholder-accepted enumeration of homeless persons with existing surveillance data to assess TB risk among the homeless in Houston, Texas. The average incidence per 100,000 was 411 among homeless and 9.5 among housed persons. The homeless were more likely than the housed to be US-born, clustered, and in a larger-sized cluster. Multivariate analysis revealed that TB rates among the homeless were driven not by comorbidities but by social determinants. Homeless patients were hospitalized more days than the housed and required more follow-up time. Reporting of TB rates for populations with known health disparities could help reframe TB prevention and better target limited funds.

Impact of a rural village women (Asha) intervention on adherence to antiretroviral therapy in southern India

BACKGROUND

Despite the increased prevalence of HIV in the rural female population of India, adherence to antiretroviral therapy continues to be low because of several barriers that discourage rural women.

OBJECTIVES

This study aims to assess the effectiveness of an intervention (Asha-Life) delivered by Accredited Social Health Activists (Asha) to improve antiretroviral therapy adherence of rural women living with AIDS in India compared with that of a usual care group.

METHODS

Sixty-eight rural women living with AIDS, aged 18-45 years, participated in a prospective, randomized pilot clinical trial and were assessed for several factors affecting adherence, such as sociodemographic characteristics, health history, CD4 cell count, enacted stigma, depressive symptomology, help getting antiretroviral therapy, and perceived therapy benefits.

RESULTS

Findings at 6 months revealed that, although both groups improved their adherence to antiretroviral therapy, there was greater improvement in the Asha-Life group (p < .001), who reported a greater reduction in barriers to antiretroviral therapy than those in the usual care group.

DISCUSSION

Antiretroviral therapy adherence showed significant increase in the Asha-Life cohort in which basic education on HIV/AIDS, counseling on antiretroviral therapy, support from Ashas, financial assistance, and better nutrition, was provided. The Asha-Life intervention may have great potential in improving antiretroviral therapy adherence and decreasing barriers among rural women living with AIDS in India.

Quality of life among tuberculosis (TB), TB retreatment and/or TB-HIV co-infected primary public health care patients in three districts in South Africa

Introduction

TB and HIV co-morbidity amount to a massive burden on healthcare systems in many countries. This study investigates health related quality of life among tuberculosis (TB), TB retreatment and TB-HIV co-infected public primary health care patients in three districts in South Africa.

Methods

A cross sectional study was conducted among 4900 TB patients who were in the first month of anti-TB treatment in primary public health care clinics in three districts in South Africa. Quality of life was assessed using the social functioning (SF)-12 Health Survey through face to face interviews. Associations of physical health (Physical health Component Summary = PCS) and mental health (Mental health Component Summary = MCS) were identified using logistic regression analyses.

Results

The overall physical and mental health scores were 42.5 and 40.7, respectively. Emotional role, general health and bodily pain had the lowest sub-scale scores, while energy and fatigue and mental health had the highest domain scores. Independent Kruskal–Wallis tests found significant positive effects of being TB-HIV co-infected on the domains of mental health functioning, emotional role, energy and fatigue, social function and physical role, while significant negative effects were observed on general health, bodily pain and physical function. In multivariable analysis higher educational, lower psychological distress, having fewer chronic conditions and being HIV negative were significantly positively associated with PCS, and low poverty, low psychological distress and being HIV positive were positively significantly associated with MCS.

Conclusion

TB and HIV weaken patients’ physical functioning and impair their quality of life. It is imperative that TB control programmes at public health clinics design strategies to improve the quality of health of TB and HIV co-infected patients.

Impact of an Asha intervention on depressive symptoms among rural women living with AIDS in India: comparison of the Asha-Life and Usual Care program

The purpose of this randomized pilot study is to conduct an intervention with 68 rural women living with AIDS to compare the effectiveness of two different programs on depressive symptoms. The trial was designed to assess the impact of the Asha-Life intervention engaging with an HIV-trained village woman, Asha (Accredited Social Health Activist), to participate in the care of women living with AIDS (WLA), along with other health care providers compared to a Usual Care group. Two high prevalence HIV/AIDS villages in rural Andhra Pradesh, which were demographically alike and served by distinct Public Health Centers, were selected randomly from a total of 16 villages. The findings of this study demonstrated that the Asha-Life participants significantly reduced their depressive symptom scores compared to the Usual Care participants. Moreover, women living with AIDS who demonstrated higher depressive symptom scores at baseline had greater reduction in their depressive symptoms than women with lower scores.

Health related quality of life among patients with tuberculosis and HIV in Thailand

Introduction

Health utilities of tuberculosis (TB) patients may be diminished by side effects from medication, prolonged treatment duration, physical effects of the disease itself, and social stigma attached to the disease.

Methods

We collected health utility data from Thai patients who were on TB treatment or had been successfully treated for TB for the purpose of economic modeling. Structured questionnaire and EuroQol (EQ-5D) and EuroQol visual analog scale (EQ-VAS) instruments were used as data collection tools. We compared utility of patients with two co-morbidities calculated using multiplicative model (U_CAL) with the direct measures and fitted Tobit regression models to examine factors predictive of health utility and to assess difference in health utilities of patients in various medical conditions.

Results

Of 222 patients analyzed, 138 (62%) were male; median age at enrollment was 40 years (interquartile range [IQR], 35–47). Median monthly household income was 6,000 Baht (187 US$; IQR, 4,000–15,000 Baht [125–469 US$]). Concordance correlation coefficient between utilities measured using EQ-5D and EQ-VAS (U_EQ-5D and U_VAS, respectively) was 0.6. U_CAL for HIV-infected TB patients was statistically different from the measured U_EQ-5D (p-value<0.01) and U_VAS (p-value<0.01). In tobit regression analysis, factors independently predictive of U_EQ-5D included age and monthly household income. Patients aged ≥40 years old rated U_EQ-5D significantly lower than younger persons. Higher U_EQ-5D was significantly associated with higher monthly household income in a dose response fashion. The median U_EQ-5D was highest among patients who had been successfully treated for TB and lowest among multi-drug resistant TB (MDR-TB) patients who were on treatment.

Conclusions

U_CAL of patients with two co-morbidities overestimated the measured utilities, warranting further research of how best to estimate utilities of patients with such conditions. TB and MDR-TB treatments impacted on patients' self perceived health status. This effect diminished after successful treatment.

A population-based assessment of the health of homeless families in New York City, 2001-2003

OBJECTIVES

We compared estimated population-based health outcomes for New York City (NYC) homeless families with NYC residents overall and in low-income neighborhoods.

METHODS

We matched a NYC family shelter user registry to mortality, tuberculosis, HIV/AIDS, and blood lead test registries maintained by the NYC Department of Health and Mental Hygiene (2001-2003).

RESULTS

Overall adult age-adjusted death rates were similar among the 3 populations. HIV/AIDS and substance-use deaths were 3 and 5 times higher for homeless adults than for the general population; only substance-use deaths were higher than for low-income adults. Children who experienced homelessness appeared to be at an elevated risk of mortality (41.3 vs 22.5 per 100,000; P < .05). Seven in 10 adult and child deaths occurred outside shelter. Adult HIV/AIDS diagnosis rates were more than twice citywide rates but comparable with low-income rates, whereas tuberculosis rates were 3 times higher than in both populations. Homeless children had lower blood lead testing rates and a higher proportion of lead levels over 10 micrograms per deciliter than did both comparison populations.

CONCLUSIONS

Morbidity and mortality levels were comparable between homeless and low-income adults; homeless children's slightly higher risk on some measures possibly reflects the impact of poverty and poor-quality, unstable housing.

Violence exposure and health related risk among African American adolescent female detainees: A strategy for reducing recidivism

Juvenile crime and violent victimization continue to be significant social problems (Fitzpatrick, Piko, Wright, & LaGory, 2005); in that, adolescents, females in particular, are likely to participate in health related risk behaviors as result of having been victimized or exposed to a violent environment. Specifically, abuse, neglect, sexual molestation, poverty, and witnessing violence are well known risk factors for the development of trauma-related psychopathology and poor outcomes relative to delinquency, drug and alcohol abuse, and HIV risk behaviors (Steiner, Garcia, & Matthews, 1997). HIV infection is a common public health concern disproportionally affecting adolescent African American female detainees. This unique population has a serious history of violence exposure, which subsequently tends to lead to engaging in risky sexual behaviors, mental health problems, and abusing substances. Also, as a result of little to no intervention, this population is recidivating at an alarming rate, a problem that may further exacerbate the expression of health-related risk behaviors among African American adolescent female detainees. The authors briefly describe a pilot program to be implemented in the juvenile justice system that is based on the Model of Accumulated Risk (Garbarino, 1996), Bronfenbrenner's Ecological Model (1994), and the Positive Youth Justice Model (Butts, Bazemore, & Meroe, 2009). The program proposes to reduce risky sexual behaviors, teach alternatives to abusing substances, treat mental health concerns, and reduce the rate of recidivism through "positive youth development", PYD (Butts, Bazemore, & Meroe, 2009). Tying elements of wraparound services and reeducation together, this program addresses salient concerns that may have an impact on an adolescent detainees' success following their release from prison in a holistic manner.

Completion and subject loss within an intensive hepatitis vaccination intervention among homeless adults: the role of risk factors, demographics, and psychosocial variables

OBJECTIVE

Unprotected sexual behavior, needle sharing, and a prison history are major correlates of hepatitis B Virus (HBV). These risk factors are common among homeless people who also have elevated rates of HBV. We examine whether these behaviors were associated with completion or loss to follow-up of the most intensive and successful condition of a 3-arm HBV vaccination intervention. Significant results would imply that those most in need are the least compliant. Contributions of baseline demographics, physical health, psychosocial variables, and health beliefs were also assessed.

DESIGN

Three-hundred thirty-one adults from Los Angeles' Skid Row were assigned to nurse-case-managed sessions with hepatitis education, incentives, and tracking. Successive predictive structural equation models assessed the amount of variance accounted for by the risk variables, demographics, and the health-related variables.

MAIN OUTCOME MEASURES

(1) Completion of 3 injections by 6 months; and (2) loss to a 6-month follow-up questionnaire.

RESULTS

The 3 risk factors explained 2% of the variance in completion and 1% of the variance in loss. Adding the other variables increased the variance explained to 14% for completion and 13% for loss. African American ethnicity, positive coping, social support, poorer health, no prison history, and greater efficacy significantly predicted completion. White ethnicity, less social support, better health, and less intention to complete predicted participant loss.

CONCLUSION

The program was not strongly rejected differentially as a function of preexisting hepatitis B risk behaviors. Programs designed for homeless people should include malleable psychosocial and health belief model variables. These aspects of the lives of homeless people provide leverage points for future interventions.

Feasibility of completing an accelerated vaccine series for homeless adults

Homeless adults are at high risk for hepatitis B virus (HBV) infection. In addition to culturally sensitive programmes designed to enhance vaccination compliance, accelerated HBV vaccination (three doses over 21 days) have also been suggested to improve compliance among high-risk groups. In this paper, we examined predictors of completers of two of three doses of a HAV/HBV vaccine series, normally delivered over a 6-month period, to simulate compliance with an accelerated series, dosed over 4 weeks. A convenience sample of 865 homeless adults was randomized into a nurse case-managed approach (NCMIT) vs standard programmes with (SIT) and without tracking (SI). Each group was assessed for completion of two of the three dose HAV/HBV vaccine series as well as the full three dose vaccine series. Sixty-eight percent of the NCMIT participants completed the three dose vaccination series at 6 months compared to 61% of SIT participants and 54% of SI participants. Eighty-one percent of the NCMIT participants completed two of the vaccinations compared to 78% of SIT participants and 73% of SI participants. The NCMIT approach resulted in greater numbers of completers of two of three doses and of the full three dose vaccine series. Predictors of completers of two doses and the full three dose vaccine series are provided. A greater number of homeless persons completed two doses across the three groups compared to the three dose vaccine series. The use of nurse case-management and tracking, coupled with an accelerated HAV/HBV vaccination schedule, may optimize vaccination compliance in homeless adults.

Measuring health-related quality of life in tuberculosis: a systematic review

INTRODUCTION

Tuberculosis remains a major public health problem worldwide. In recent years, increasing efforts have been dedicated to assessing the health-related quality of life experienced by people infected with tuberculosis. The objectives of this study were to better understand the impact of tuberculosis and its treatment on people's quality of life, and to review quality of life instruments used in current tuberculosis research.

METHODS

A systematic literature search from 1981 to 2008 was performed through a number of electronic databases as well as a manual search. Eligible studies assessed multi-dimensional quality of life in people with tuberculosis disease or infection using standardized instruments. Results of the included studies were summarized qualitatively.

RESULTS

Twelve original studies met our criteria for inclusion. A wide range of quality of life instruments were involved, and the Short-Form 36 was most commonly used. A validated tuberculosis-specific quality of life instrument was not located. The findings showed that tuberculosis had a substantial and encompassing impact on patients' quality of life. Overall, the anti-tuberculosis treatment had a positive effect of improving patients' quality of life; their physical health tended to recover more quickly than the mental well-being. However, after the patients successfully completed treatment and were microbiologically 'cured', their quality of life remained significantly worse than the general population.

CONCLUSION

Tuberculosis has substantially adverse impacts on patients' quality of life, which persist after microbiological 'cure'. A variety of instruments were used to assess quality of life in tuberculosis and there has been no well-established tuberculosis-specific instrument, making it difficult to fully understand the impact of the illness.

Effects of a nurse-managed program on hepatitis A and B vaccine completion among homeless adults

BACKGROUND

Hepatitis B virus (HBV) infection constitutes a major health problem for homeless persons. Ability to complete an HBV vaccination series is complicated by the need to prioritize competing needs, such as addiction issues, safe places to sleep, and food, over health concerns.

OBJECTIVES

The objectives of this study were to evaluate the effectiveness of a nurse-case-managed intervention compared with that of two standard programs on completion of the combined hepatitis A virus (HAV) and HBV vaccine series among homeless adults and to assess sociodemographic factors and risk behaviors related to the vaccine completion.

METHODS

A randomized, three-group, prospective, quasi-experimental design was conducted with 865 homeless adults residing in homeless shelters, drug rehabilitation sites, and outdoor areas in the Skid Row area of Los Angeles. The programs included (a) nurse-case-managed sessions plus targeted hepatitis education, incentives, and tracking (NCMIT); (b) standard targeted hepatitis education plus incentives and tracking (SIT); and (c) standard targeted hepatitis education and incentives only (SI).

RESULTS

Sixty-eight percent of the NCMIT participants completed the three-series vaccine at 6 months, compared with 61% of SIT participants and 54% of SI participants. NCMIT participants had almost 2 times greater odds of completing vaccination than those of participants in the SI program. Completers were more likely to be older, to be female, to report fair or poor health, and not to have participated in a self-help drug treatment program. Newly homeless White adults were significantly less likely than were African Americans to complete the vaccine series.

DISCUSSION

The use of vaccination programs incorporating nurse case management and tracking is critical in supporting adherence to completion of a 6-month HAV/HBV vaccine. The finding that White homeless persons were the least likely to complete the vaccine series suggests that programs tailored to address their unique cultural issues are needed.
