Improving access to tuberculosis preventive treatment for children in Ethiopia: designing a home-based contact management intervention for the CHIP-TB trial through formative research.

BACKGROUND: Tuberculosis (TB) preventive treatment (TPT) is a long-standing recommendation for children exposed to TB but remains poorly implemented. Home-based contact management may increase access and coverage of TPT among children exposed to TB in their households. METHODS: Sixty in-depth interviews were conducted with key informants including program managers, TB providers (known as TB focal persons), health extension workers and caregivers whose children had recently engaged with TB prevention services in Oromia, Ethiopia in 2021 to understand the barriers and facilitators to providing home-based TB prevention services for children aged < 15 years. Thematic content analysis was conducted including systematically coding each interview. RESULTS: Home-based services were considered a family-centered intervention, addressing the time and financial constraints of clients. Stakeholders proposed a task-shared intervention between health extension workers and facility-based TB focal persons. They recommended that TB services be integrated into other home-based services, including HIV, nutrition, and vaccination services to reduce workload on the already overstretched health extension workers. Community awareness was considered essential to improve acceptability of home-based services and TPT in general among community members. CONCLUSIONS: Decentralization of TPT should be supported by task-sharing initiation and follow up between health extension workers and facility-based TB focal persons and integration of home-based services. Active community engagement through several existing mechanisms can help improve acceptability for both home-based interventions and TPT promotion overall for children. TRIAL REGISTRATION: The results presented here were from formative research related to the CHIP-TB Trial (Identifier NCT04369326) registered on April 30, 2020. This qualitative study was separately registered at NCT04494516 on 27 July 2020.

Effects of Training-for-Transformation Program on TB/MDR-TB Developed by the International Council of Nurses in China.

BACKGROUND: This study evaluated the effects of the Training-for-Transformation (TFT) program on tuberculosis (TB)/multidrug-resistant TB (MDR-TB) in China. METHOD: Participants who received training from 2009 to 2017 (n = 230) were invited to complete an online survey using a self-designed questionnaire. RESULTS: A total of 130 (56.5%) trainees completed the survey for a valid response rate of 70% (91 of 130). All of the participants created a schedule and offered a TFT program on TB/MDR-TB for health care providers, clients, and communities by a variety of methods that included brainstorming, group work, and role-play, in addition to lectures. The most important supporting factors to train others were related to opportunity and managers' support, and the biggest barriers were lack of space and time. Trainees also made changes to practices that influenced the way nurses worked within their institution, infection control, team cooperation, extended care, and nurses' attitudes toward patients. CONCLUSION: The TFT program led to ongoing training provision and practical improvements, and can transform attitudes, practices, and changes in patient care.

Maternal Motivation to Take Preventive Therapy in Antepartum and Postpartum Among HIV-Positive Pregnant Women in South Africa: A Choice Experiment.

HIV-positive pregnant women who are initiated on lifelong antiretroviral therapy (ART) and isoniazid preventive therapy (IPT) have lower adherence rates after delivery. We quantified maternal motivation to take preventive therapy before and after delivery among pregnant women newly diagnosed with HIV. We enrolled pregnant women (≥ 18 years) with a recent HIV diagnosis (< 6 months) at 14 public primary health clinics in Matlosana, South Africa and followed them in the postpartum period. Participants received eight choice tasks comparing two mutually exclusive sub-sets of seven possible benefits related to preventive therapy identified through literature reviews and key informant interviews. Data was analyzed using conditional logit regression in the antepartum versus postpartum periods. Coefficients are reported with 95% confidence intervals (CI). Sixty-five women completed surveys both at enrollment and in the postpartum period. All women were already on ART, while 21 (32%) were receiving IPT at enrollment. The mean CD4 count was 436 (± 246) cells/mm3. In the antepartum period, preventing HIV transmission to partners was the most important benefit (coefficients (ß) = 0.87, 95% CI 0.64, 1.11), followed by keeping healthy for family (ß = 0.75, 95% CI 0.52, 0.97). Such prioritization significantly decreased in the postpartum period (p < 0.001). Compared to other motivators, keeping a high CD4 count was least prioritized in the antepartum period (ß = 0.19, 95% CI - 0.04, 0.43) but was most prioritized in the postpartum period (ß = 0.39, 95% CI 0.21, 0.57). These results highlight that messages on family might be particularly salient in the antepartum period, and keeping CD4 count high in the postpartum period. Understanding maternal motivation may help to design targeted health promotion messages to HIV-positive women around the time of delivery.

Relevance and acceptability of using the Quantiferon gold test (QGIT) to screen CD4 blood draws for latent TB infection among PLHIV in South Africa: formative qualitative research findings from the TEKO trial.

BACKGROUND: Tuberculosis (TB) is the leading cause of mortality among people living with HIV (PLHIV), despite the availability of effective preventive therapy. The TEKO trial is assessing the impact of using a blood test, Quantiferon-TB Gold In-Tube Test (QGIT), to screen for latent TB compared to the Tuberculin Screening Test (TST) among PLHIV in South Africa. METHODS: Fifty-six qualitative interviews were conducted with PLHIV and clinical providers participating in the TEKO trial. We explored TB screening, diagnosis, and treatment guidelines and processes and the use of the QGIT to screen for latent TB infection at the time of CD4 blood draw. Thematic content analysis was conducted. RESULTS: Considerable variability in TB screening procedures was documented due to lack of personnel and clarity regarding current national TB guidelines for PLHIV. Few clinics had started using the TST per national guidelines and many patients had never heard of isoniazid preventive therapy (IPT). Nearly all participants supported the idea of latent TB screening using routine blood drawn for CD4 counts. CONCLUSIONS: Findings indicate that screening for latent TB infection using QGIT from blood drawn for CD4 counts among PLHIV is an acceptable approach to increase latent TB detection given the challenges associated with ensuring systematic latent TB screening in overburdened public clinics. TRIAL REGISTRATION: The results presented here were from formative research related to the TEKO trial (Identifier NCT02119130 , registered 10 April 2014).

Improving active case finding for tuberculosis in South Africa: informing innovative implementation approaches in the context of the Kharitode trial through formative research.

BACKGROUND: Tuberculosis (TB) is the leading infectious killer worldwide, with approximately 1.8 million deaths in 2015. While effective treatment exists, implementation of active case finding (ACF) methods to identify persons with active TB in a timely and cost-effective manner continues to be a major challenge in resource-constrained settings. Limited qualitative work has been conducted to gain an in-depth understanding of implementation barriers. METHODS: Qualitative research was conducted to inform the development of three ACF strategies for TB to be evaluated as part of the Kharitode cluster-randomised trial being conducted in a rural province of South Africa. This included 25 semi-structured in-depth interviews among 8 TB patients, 7 of their household members and 10 clinic health workers, as well as 4 focus group discussions (2 rural and 2 main town locations) with 6-8 participants each (n = 27). Interviews and focus group discussions explored the context, advantages and limitations, as well as the implications of three ACF methods. Content analysis was utilised to document salient themes regarding their feasibility, acceptability and potential effectiveness. RESULTS: Study participants (TB patients and community members) reported difficulty identifying TB symptoms and seeking care in a timely fashion. In turn, all stakeholder groups felt that more proactive case finding strategies would be beneficial. Clinic-based strategies (including screening all patients regardless of visit purpose) were seen as the most acceptable method based on participants' preference ranking of the ACF strategies. However, given the resource constraints experienced by the public healthcare system in South Africa, many participants doubted whether it would be the most effective strategy. Household outreach and incentive-based strategies were described as promising, but participants reported some concerns (e.g. stigma in case of household-based and ethical concerns in the case of incentives). Participants offered insights into how to optimise each strategy, tailoring implementation to community needs (low TB knowledge) and realities (financial constraints, transport, time off from work). CONCLUSIONS: Findings suggest different methods of TB ACF are likely to engage different populations, highlighting the utility of a comprehensive approach. TRIAL REGISTRATION: Clinicaltrials.gov ( NCT02808507 ). Registered June 1, 2016. The participants in this formative study are not trial participants.

Occupational Risk Factors for Tuberculosis Among Healthcare Workers in KwaZulu-Natal, South Africa.

BACKGROUND: Tuberculosis is a known occupational hazard for healthcare workers (HCWs), especially in countries with a high burden of tuberculosis. It is estimated that HCWs have a 2- to 3-fold increased risk of developing tuberculosis compared with the general population. The objective of this study was to identify occupational risk factors for tuberculosis among HCWs in 3 district hospitals with specialized multidrug-resistant tuberculosis wards in KwaZulu-Natal, South Africa. METHODS: We conducted a case-control study of HCWs diagnosed with tuberculosis between January 2006 and December 2010. Cases and controls were asked to complete a self-administered questionnaire regarding potential risk factors for tuberculosis. RESULTS: Of 307 subjects selected, 145 (47%) HCWs responded to the questionnaire; 54 (37%) tuberculosis cases and 91 (63%) controls. Cases occurred more frequently among clinical staff 46% (n = 25) and support staff 35% (n = 19). Thirty-two (26% [32/125]) HCWs were known to be infected with human immunodeficiency virus (HIV), including 45% (21/54) of cases. HCWs living with HIV (odds ratio [OR], 6.35; 95% confidence interval [CI], 3.54-11.37) and those who spent time working in areas with patients (OR, 2.24; 95% CI, 1.40-3.59) had significantly greater odds of developing tuberculosis, controlling for occupation, number of wards worked in, and household crowding. CONCLUSIONS: HIV was the major independent risk factor for tuberculosis among HCWs in this sample. These findings support the need for HCWs to know their HIV status, and for HIV-infected HCWs to be offered antiretroviral therapy and isoniazid preventive therapy. Infection prevention and control should also be improved to prevent transmission of tuberculosis in healthcare settings to protect both HCWs and patients.

Symptom frequency, severity, and quality of life among persons with three disease trajectories: cancer, ALS, and CHF.

PURPOSE: National reports on end-of-life symptom management reveal a gap in the evidence regarding symptoms other than pain and studies of diseases other than cancer. This study examines the frequency and severity of symptoms and quality of life (QOL) in persons with advanced cancer, amyotrophic lateral sclerosis (ALS), and congestive heart failure (CHF). METHODS: The present study is a cross-sectional examination of symptoms and QOL measured using the McGill QOL Questionnaire, among 147 participants. RESULTS: Forty one percent of participants had advanced cancer, 22% had ALS, and 37% had advanced CHF. A total of 266 symptoms were reported, with the common symptom categories being discomfort/pain, weakness/fatigue/sleep, and respiratory. Participants with CHF had the highest mean symptom severity and the lowest QOL. CONCLUSION: Clinicians should be aware and attentive for symptoms other than pain in patients with advanced illness. Studies on diseases other than cancer, such as CHF and ALS, are important to improve symptom management in all disease groups.

Tuberculosis among health care workers in KwaZulu-Natal, South Africa: a retrospective cohort analysis.

BACKGROUND: Tuberculosis (TB) is an occupational hazard for health care workers (HCWs) who are at greater risk of developing TB than the general population. The objective of this study was to compare the difference in TB incidence among HCWs with versus without a history of working in TB wards, to estimate the incidence of TB among HCWs, and to identify risk factors for TB disease in HCWs. METHODS: A retrospective cohort study (January 2006 to December 2010) was conducted in three district hospitals in KwaZulu-Natal, South Africa. Data were abstracted via chart review from occupational health medical records. Bivariate and multivariate analyses were performed using a Poisson multilevel mixed model. RESULTS: Of 1,313 (92%) medical charts reviewed with data on location of work documented, 112 (9%) cases of TB were identified. Among HCWs with TB 14 (13%) had multidrug-resistant TB. Thirty-six (32%) were cured, 33 (29%) completed treatment, and 13 (12%) died. An increased incidence of TB was reported for HCWs with a history of working in TB wards (incidence rate ratio [IRR] 2.03, 95% CI 1.11-3.71), pediatric wards (IRR 1.82 95% CI 1.07-3.10), outpatient departments (IRR 2.08 95% CI 1.23-3.52), and stores/workshop (IRR 2.38 95% CI 1.06-5.34) compared with those without such a history. HCWs living with HIV had a greater incidence of TB (IRR 3.2, 95% CI 1.54-6.66) than HIV-negative HCWs. TB incidence among HCWs was approximately two-fold greater than that of the general population over the study period. CONCLUSIONS: HCWs working in a TB ward had an increased incidence of TB. However, a greater incidence of TB was also found in HCWs working in other wards including pediatric wards, outpatient departments and stores. We also identified a greater incidence of TB among HCWs than the general population. These findings further support the need for improved infection control measures not only in TB or drug-resistant TB wards or areas perceived to be at high-risk but also throughout hospitals to protect HCWs. Additionally, it is recommended for occupational health services to routinely screen HCWs for TB and provide HCWs with access to care for TB and HIV.

The tibetan uterotonic zhi byed 11: mechanisms of action, efficacy, and historical use for postpartum hemorrhage.

Objective. To explore evidence for the traditional Tibetan medicine, Zhi Byed 11 (ZB11), for use as a uterotonic. Methods. The eleven ingredients in ZB11 were chemically analyzed by mass spectroscopy. A review was conducted of Western allopathic literature for scientific studies on ZB11's individual components. Literature from Tibetan and other traditional paradigms were reviewed. Results. Potential mechanisms of action for ZB11 as a uterotonic include laxative effects, a dose-dependant increase in smooth muscle tissue peristalsis that may also affect the uterus smooth muscle, and chemical components that are prostaglandin precursors and/or increase prostaglandin synthesis. A recent RCT demonstrated comparable efficacy to misoprostol in reducing severe postpartum hemorrhage (PPH) (>1000 mL) and greater effect than placebo. Historical and anecdotal evidence for ZB11 and its ingredients for childbirth provide further support. Discussion. ZB11 and its ingredients are candidates for potentially effective uterotonics, especially in low-resource settings. Further research is warranted to understand the mechanisms of action and synergy between ingredients.

Family understanding of seriously-ill patient preferences for family involvement in healthcare decision making.

BACKGROUND: Surrogate accuracy in predicting patient treatment preferences (i.e., what patients want) has been studied extensively, but it is not known whether surrogates can predict how patients want loved ones to make end-of-life decisions on their behalf. OBJECTIVE: To evaluate the ability of family members to correctly identify the preferences of seriously-ill patients regarding family involvement in decision making. DESIGN: Cross-sectional survey. PARTICIPANTS: Twenty-five pancreatic cancer and 27 amyotrophic lateral sclerosis (ALS) patients and their family members (52 dyads total). MAIN MEASURES: Patients and family members completed the Decision Control Preferences (DCP) scale regarding patient preferences for family involvement in health care decisions using conscious and unconscious scenarios. KEY RESULTS: Patient and family member agreement was 56% (29/52 dyads) for the conscious scenario (kappa 0.29) and 46% (24/52 dyads) for the unconscious scenario (kappa 0.15). Twenty-four family members identified the patient's preference as independent in the unconscious scenario, but six of these patients actually preferred shared decision making and six preferred reliant decision making. In the conscious scenario, preference for independent decision making was associated with higher odds of patient-family agreement (AOR 5.28, 1.07-26.06). In the unconscious scenario, cancer patients had a higher odds of agreement than ALS patients (AOR 3.86; 95% CI 1.02-14.54). CONCLUSION: Family members were often unable to correctly identify patient preferences for family involvement in end-of-life decision making, especially when patients desired that decisions be made using the best-interest standard. Clinicians and family members should consider explicitly eliciting patient preferences for family involvement in decision making. Additional research is still needed to identify interventions to improve family member understanding of patient preferences regarding the decision-making process itself.

Employers' Perceptions of Intimate Partner Violence among a Diverse Workforce.

OBJECTIVES: Intimate partner violence (IPV) is a significant global public health concern, affecting 5.3 million US individuals annually. An estimated 1 in 3 women globally are abused by an intimate partner in their lifetime, and the effects carry over into the workplace. This article examines employers' perceptions of IPV in the workplace, targeting supervisors of Latina employees. METHODS: Fourteen employers and supervisors of small service-sector companies in Oregon were interviewed using semi-structured interviews. Interpretive description was used to identify themes. These qualitative interviews preceded and helped to formulate a larger workplace intervention study. RESULTS: THE FOLLOWING THEMES WERE FOUND AND ARE DETAILED: (1) factors associated with recognizing IPV in the workplace, (2) effects of IPV on the work environment and (3) supervisors' responses to IPV-active vs. passive involvement. Also, supervisors' suggestions for addressing IPV in the workplace are summarized. CONCLUSION: These findings demonstrate the need for more IPV-related resources in the workplace to be available to supervisors as well as survivors and their coworkers. The needs of supervisors and workplaces vary by site, demonstrating the need for tailored interventions, and culturally appropriate workplace interventions are needed for Latinas and other racially and ethnically diverse populations.

Randomized double masked trial of Zhi Byed 11, a Tibetan traditional medicine, versus misoprostol to prevent postpartum hemorrhage in Lhasa, Tibet.

The objective of this study was to compare a Tibetan traditional medicine (the uterotonic Zhi Byed 11 [ZB11]) to oral misoprostol for prophylaxis of postpartum hemorrhage (PPH). We conducted a double-blind randomized controlled trial at three hospitals in Lhasa, Tibet, People's Republic of China. Women (N = 967) were randomized to either ZB11 or misoprostol groups. Postpartum blood loss was measured in a calibrated blood collection drape. The primary combined outcome was incidence of PPH, defined as measured blood loss (MBL) > or = 500 mL, administration of open label uterotonics, or maternal death. We found that the rate of the combined outcome was lower among the misoprostol group (16.1% versus 21.8% for ZB11; P = .02). Frequency of PPH was lower with misoprostol (12.4% versus 17.4%; P = .02). There were no significant differences in MBL > 1000 mL or mean or median MBL. Fever was significantly more common in the misoprostol group (P = .03). The rate of combined outcome was significantly lower among women receiving misoprostol. However, other indices of obstetric hemorrhage were not significantly different.

Comparison of maternal and newborn outcomes of Tibetan and Han Chinese delivering in Lhasa, Tibet.

AIM: To compare maternal and neonatal outcomes of Tibetan and Han Chinese women delivering vaginally at high altitude (3650 meters) in Lhasa, Tibet Autonomous Region, People's Republic of China. METHOD: Comparative analysis of data from a prospective observational study of Tibetan (n = 938) and Han Chinese (n = 146) women delivering at three hospitals between January 2004 and May 2005. RESULTS: Han Chinese women had higher rates of pre-eclampsia/gestational hypertension than Tibetan women, (10.3% vs 5.9%, P = 0.04). There was no difference in rates of postpartum hemorrhage between Tibetan and Han women (12.8% vs 17.1%, P = 0.15). Han newborns weighed significantly less than Tibetan newborns (P < 0.01), and were twice as likely to be small for gestational age, (24.5% vs 11.6%, P < 0.01). Tibetan newborns were less likely to have poor neonatal outcomes than Han newborns (P < 0.01). CONCLUSION: In high altitude deliveries in Tibet, adverse outcomes were significantly more common among Han Chinese.
