- Under-detection and -reporting in the private sector constitute a major barrier in Viet Nam’s fight to end tuberculosis (TB). Effective private-sector engagement requires innovative approaches. We established an intermediary agency that incentivized private providers in two districts of Ho Chi Minh City to refer persons with presumptive TB and share data of unreported TB treatment from July 2017 to March 2019. We subsidized chest x-ray screening and Xpert MTB/RIF testing, and supported test logistics, recording, and reporting. Among 393 participating private providers, 32.1% (126/393) referred at least one symptomatic person, and 3.6% (14/393) reported TB patients treated in their practice. In total, the study identified 1203 people with TB through private provider engagement. Of these, 7.6% (91/1203) were referred for treatment in government facilities. The referrals led to a post-intervention increase of +8.5% in All Forms TB notifications in the intervention districts. The remaining 92.4% (1112/1203) of identified people with TB elected private-sector treatment and were not notified to the NTP. Had this private TB treatment been included in official notifications, the increase in All Forms TB notifications would have been +68.3%. Our evaluation showed that an intermediary agency model can potentially engage private providers in Viet Nam to notify many people with TB who are not being captured by the current system. This could have a substantial impact on transparency into disease burden and contribute significantly to the progress towards ending TB.

Psychological Resources and Risk Factors in Coronary Heart Disease : Assessment, Impact and the Influence of Mindfulness Training
- 2018

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There is strong evidence for the observation that psychological risk factors, such as depressive symptoms, hopelessness, and anxiety are associated with higher risk of developing coronary heart disease (CHD), and also contribute to a worse prognosis among CHD patients. Much less is known about psychological resources, such as Mastery, and their role in cardiovascular medicine. Although the current state of science about the importance of psychological factors has advanced during the last decades, the mental health status of patients is often neglected in clinical practice. The reason behind this gap is multifaceted, including unawareness of the current state of science among professionals and a lack of clear guideline, which in turn, results from a lack of evidence-based ways to address the issues. Furthermore, the measurement of psychological resources is complex and a debated topic in psychology. The aim of this thesis was to investigate: 1) If the use of inverted items in three questionnaires that measure psychological resources and risk factors represent a validity risk in the context of CHD. 2) If psychological resources and risk factors are independently associated with incidence in CHD. 3) If an eight-week course in Mindfulness-Based Stress Reduction (MBSR) is a feasible psychological intervention, as an addition to cardiac rehabilitation. 4) How CHD patients experience the practices of mindfulness and yoga in MBSR.In Study I and II, data from 1007 participants randomly selected from a Swedish community sample, aged 45-69 at baseline (50 % women), were analysed. To study the validity of the self-report instruments Mastery, Self-esteem and Centre for Epidemiological Studies Depression scale (CESD), subscales with only positive and negative items were created. The new subscales were evaluated against three criterion measures; cross-sectional against each other and the circulatory marker of inflammation interleukine-6 (IL-6) (concurrent construct validity); prospectively against 8-year incidence in CHD (predictive validity), and in addition, a factor analysis was used to investigate construct dimensionality. The instruments seemed to be valid measures of psychological resources and risk factors in the context of CHD risk. The new subscales showed the same associations as the original scales, except for the positive items in CES-D. However, this did not have a major influence on the full scale. In Study II a prospective analysis of the impact of psychological factors on 8-year incidence in CHD was performed. The psychological resources Mastery and Self-esteem were negatively associated with CHD, also after adjustment for nine traditional cardiovascular risk factors in Cox proportional hazard models. The protective effect of the two resources, and the increased risk of Hopelessness, remained after adjustment for depressive symptoms. In Study III and IV, a group of CHD patients with depressive symptoms (n=79) was invited to participate in MBSR as a complement to cardiac rehabilitation. Twenty-four patients started MBSR and 16 completed it. The results were compared with a reference group (n=108) of patients from the same clinic, which showed stability in psychological variables over 12 months. MBSR was appreciated by the patients and improvements in psychological risk factors (e.g., depressive symptoms), and an increase in Mastery were observed. Study IV made use of a qualitative content analysis of diary entries written by patients immediately after practice sessions throughout MBSR. Participants described difficulties, both physical and psychological, during the whole course, but as the weeks passed they more frequently described an enhanced ability to concentrate, relax and deal with distractions. From the combined findings in Study III and IV, we conclude that MBSR could be a promising complement to cardiac rehabilitation for a selection of patients.The overall picture, emerging from this thesis, strengthens the argument that psychological factors should be recognized and addressed in clinical practice. It also encourages further studies of how psychological resources could be built, which could inform the development of effective prevention and treatment strategies for CHD patients with psychological distress and also contribute to improved public health interventions.

- To accelerate the reduction in tuberculosis (TB) incidence, it is necessary to optimize the use of innovative tools and approaches available within a local context. This study evaluated the use of an existing network of community health workers (CHW) for active case finding, in combination with mobile chest X-ray (CXR) screening events and the expansion of Xpert MTB/RIF testing eligibility, in order to reach people with TB who had been missed by the current system. A controlled intervention study was conducted from January 2018 to March 2019 in five intervention and four control districts of two low to medium TB burden cities in Viet Nam. CHWs screened and referred eligible persons for CXR to TB care facilities or mobile screening events in the community. The initial diagnostic test was Xpert MTB/RIF for persons with parenchymal abnormalities suggestive of TB on CXR or otherwise on smear microscopy. We analyzed the TB care cascade by calculating the yield and number needed to screen (NNS), estimated the impact on TB notifications and conducted a pre-/postintervention comparison of TB notification rates using controlled, interrupted time series (ITS) analyses. We screened 30,336 individuals in both cities to detect and treat 243 individuals with TB, 88.9% of whom completed treatment successfully. All forms of TB notifications rose by +18.3% (95% CI: +15.8%, +20.8%). The ITS detected a significant postintervention step-increase in the intervention area for all-form TB notification rates (IRR(β6) = 1.221 (95% CI: 1.011, 1.475); p = 0.038). The combined use of CHWs for active case findings and mobile CXR screening expanded the access to and uptake of Xpert MTB/RIF testing and resulted in a significant increase in TB notifications. This model could serve as a blueprint for expansion throughout Vietnam. Moreover, the results demonstrate the need to optimize the use of the best available tools and approaches in order to end TB.

- Across Asia, a large proportion of people with tuberculosis (TB) do not report symptoms, have mild symptoms or only experience symptoms for a short duration. These individuals may not seek care at health facilities or may be missed by symptom screening, resulting in sustained TB transmission in the community. We evaluated the yields of TB from 114 days of community-based, mobile chest X-ray (CXR) screening. The yields at each step of the TB screening cascade were tabulated and we compared cohorts of participants who reported having a prolonged cough and those reporting no cough or one of short duration. We estimated the marginal yields of TB using different diagnostic algorithms and calculated the relative diagnostic costs and cost per case for each algorithm. A total of 34,529 participants were screened by CXR, detecting 256 people with Xpert-positive TB. Only 50% of those diagnosed with TB were detected among participants reporting a prolonged cough. The study’s screening algorithm detected almost 4 times as much TB as the National TB Program’s standard diagnostic algorithm. Community-based, mobile chest X-ray screening can be a high yielding strategy which is able to identify people with TB who would likely otherwise have been missed by existing health services.

- Guided self-help is an evidence-based intervention used globally. Self-help is a fundamental part of the stepped care model of mental health services that enables the efficient use of limited resources. Despite its importance, there is little information defining the role of the guide and the key competences required. In this context, the guide is defined as the person who facilitates and supports the use self-help materials. This article sets out the role of the guide in guided self-help. It considers practical issues such as the importance of engagement to motivate clients for early change, personalising the intervention, structuring sessions, how best to use routine outcome monitoring and supervision requirements. Key competences are proposed, including generic competences to build the relationship as well as specific competences such as being able to clearly convey the role of the guide to clients. Guides should be prepared for “self-help drift”, a concept akin to therapist drift in more traditional therapies. Knowing how to identify mental health problems, use supervision and manage risk and comorbidity are all key requirements for guides. The paper concludes by calling for increased recognition and value of the role of the guide within mental health services.
