Barriers to engagement in the care cascade for tuberculosis disease in India: A systematic review of quantitative studies.

BACKGROUND: India accounts for about one-quarter of people contracting tuberculosis (TB) disease annually and nearly one-third of TB deaths globally. Many Indians do not navigate all care cascade stages to receive TB treatment and achieve recurrence-free survival. Guided by a population/exposure/comparison/outcomes (PECO) framework, we report findings of a systematic review to identify factors contributing to unfavorable outcomes across each care cascade gap for TB disease in India. METHODS AND FINDINGS: We defined care cascade gaps as comprising people with confirmed or presumptive TB who did not: start the TB diagnostic workup (Gap 1), complete the workup (Gap 2), start treatment (Gap 3), achieve treatment success (Gap 4), or achieve TB recurrence-free survival (Gap 5). Three systematic searches of PubMed, Embase, and Web of Science from January 1, 2000 to August 14, 2023 were conducted. We identified articles evaluating factors associated with unfavorable outcomes for each gap (reported as adjusted odds, relative risk, or hazard ratios) and, among people experiencing unfavorable outcomes, reasons for these outcomes (reported as proportions), with specific quality or risk of bias criteria for each gap. Findings were organized into person-, family-, and society-, or health system-related factors, using a social-ecological framework. Factors associated with unfavorable outcomes across multiple cascade stages included: male sex, older age, poverty-related factors, lower symptom severity or duration, undernutrition, alcohol use, smoking, and distrust of (or dissatisfaction with) health services. People previously treated for TB were more likely to seek care and engage in the diagnostic workup (Gaps 1 and 2) but more likely to suffer pretreatment loss to follow-up (Gap 3) and unfavorable treatment outcomes (Gap 4), especially those who were lost to follow-up during their prior treatment. For individual care cascade gaps, multiple studies highlighted lack of TB knowledge and structural barriers (e.g., transportation challenges) as contributing to lack of care-seeking for TB symptoms (Gap 1, 14 studies); lack of access to diagnostics (e.g., X-ray), non-identification of eligible people for testing, and failure of providers to communicate concern for TB as contributing to non-completion of the diagnostic workup (Gap 2, 17 studies); stigma, poor recording of patient contact information by providers, and early death from diagnostic delays as contributing to pretreatment loss to follow-up (Gap 3, 15 studies); and lack of TB knowledge, stigma, depression, and medication adverse effects as contributing to unfavorable treatment outcomes (Gap 4, 86 studies). Medication nonadherence contributed to unfavorable treatment outcomes (Gap 4) and TB recurrence (Gap 5, 14 studies). Limitations include lack of meta-analyses due to the heterogeneity of findings and limited generalizability to some Indian regions, given the country's diverse population. CONCLUSIONS: This systematic review illuminates common patterns of risk that shape outcomes for Indians with TB, while highlighting knowledge gaps-particularly regarding TB care for children or in the private sector-to guide future research. Findings may inform targeting of support services to people with TB who have higher risk of poor outcomes and inform multicomponent interventions to close gaps in the care cascade.

Multidrug-resistant Salmonella spp. in fecal samples of pigs with suspected salmonellosis in Antioquia, Colombia, 2019-2021.

Objectives: To determine the proportion of Salmonella enterica in fecal samples of live pigs with suspected salmonellosis analyzed at the diagnostic unit of the University of Antioquia, Colombia between 2019 and 2021, and examine the serotypes and antimicrobial resistance patterns. Methods: This was a laboratory-based cross-sectional study of routine data on fecal samples received from pig farms in all nine subregions of Antioquia state, Colombia. Salmonella spp. detection at the university is done using enrichment, selective culture, and polymerase chain reaction. Serotypes were identified using the Kauffmann-White scheme and isolates were tested for antimicrobial susceptibility using broth microdilution. Results: Of 653 samples tested, 149 (23%) were positive for S. enterica. Nine serotypes were identified. The most common were Salmonella Typhimurium (56%) and its monophasic variant (35%). Resistance to ampicillin (70%) was most frequently observed, followed by ciprofloxacin (55%), and sulfamethoxazole-trimethoprim (52%). No isolates were resistant to amikacin and gentamicin. Multidrug resistance (resistance to ≥ 3 classes of antibiotics) was observed in 61 (44%) isolates. Multidrug resistance was highest in S. Typhimurium (57%) compared with the other serotypes. Serotype was associated with multidrug resistance (p = 0.01), but age of the pig and sub-region were not. Conclusions: The proportion of Salmonella spp. and the associated high levels of multidrug resistance are of concern and may indicate irrational use of antimicrobials and poor management practices in pig production systems in the region. Strengthened surveillance is needed to monitor and improve farm management practices and the use of antimicrobials in farms in Colombia.

Effectiveness and cardiovascular safety of delamanid-containing regimens in adults with multidrug-resistant or extensively drug-resistant tuberculosis: A nationwide cohort study from Belarus, 2016-18.

To address the sub-optimal treatment outcomes among patients with multidrug-resistant (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB), the National TB Programme in Belarus started using new drugs such as bedaquiline and delamanid in 2015-16. In this study, we assessed cardiovascular safety and effectiveness (culture conversion, treatment outcomes and post-treatment recurrence) of delamanid-containing regimens among adults (>18 years) with MDR-TB or XDR-TB from June 2016 to February 2018. This was a nationwide cohort study involving analysis of routinely collected programme data from the national and six regional TB hospitals. Cardiovascular adverse events (AEs) were classified as serious or not, based on international guidelines. We conducted Cox proportional hazards regression and calculated adjusted hazards ratio(aHR) and 95% confidence intervals(CI) to evaluate factors associated with AEs and unsuccessful treatment outcomes (death, failure and lost-to-follow-up). Of 125 patients enrolled (35, 28% females; mean age 43 years), 85(68%) had XDR-TB. All the patients received delamanid and 20 patients received both delamanid and bedaquiline. Cardiovascular AEs (177 episodes in total), were observed in the majority (73%) of patients but were mild and managed easily. The most common cardiovascular AEs were QTcF prolongation (64/177, 36%) and other electrocardiography (ECG) abnormalities (40/177, 23%). There were two instances of serious AEs leading to death, both of which were not related to delamanid. In multivariable analysis, male sex (aHR 0.72; 95% CI 0.51-0.99), and baseline ECG abnormalities (aHR 1.68; 95% CI 1.19-2.36) were associated with cardiovascular AEs. Median time to culture conversion was 1.1 months (interquartile range: 1.0-2.1). Culture conversion was observed in 115 (92%) patients at six months of treatment and 110 (88%) completed the treatment successfully. Loss to follow-up, failure and death were observed in 6%, 4% and 2% patients respectively. Among those assessed at 12 months post-treatment (n=33), recurrence was seen in one patient. The only factor associated with unsuccessful treatment outcomes in multivariable analysis was baseline Hepatitis C co-infection (aHR 3.61; 95% CI 1.09-11.95). In conclusion, treatment using delamanid-containing regimens was effective and had a favourable safety profile. We hope our findings inform the development of national clinical guidelines and scale-up of new drugs in other countries.

Factors associated with unfavourable treatment outcomes among people with rifampicin-resistant tuberculosis in Armenia, 2014-2017.

Rifampicin-Resistant/Multidrug-Resistant Tuberculosis (RR/MDR-TB) is recognized as a major public health concern globally. In Armenia, the proportion of RR/MDR-TB is increasing among all people affected with TB. We conducted a nationwide cohort study involving analysis of programmatic data to investigate the rates of and factors associated with unfavourable treatment outcomes among patients with RR/MDR-TB registered by the national TB programme from 2014 to 2017 in Armenia. We used Cox regression to identify factors associated with the outcome. Among 451 RR/MDR-TB patients, 80% were men and median age was 46 years. Of them, 53 (11.8%) had Extensively Drug-Resistant Tuberculosis (XDR-TB) and 132 (29.3%) had pre-XDR-TB. Almost half (224, 49.7%) of the patients had unfavourable treatment outcome, which included 26.8% Loss To Follow-Up (LTFU), 13.3% failures and 9.5% deaths. In multivariable analysis, people with pre-XDR-TB [adjusted Hazard Ratio [aHR] 3.13, 95% confidence intervals [CI] 2.16-4.55] and XDR-TB (aHR 4.08, 95% CI 2.45-6.79) had a higher risk of unfavourable outcomes. Patients receiving home-based treatment (71/451, 15.7%) and treatment with new drugs (172/451, 38.1%) had significantly lower risk (aHR 0.45, 95% CI 0.28-0.72 and aHR 0.26, 95% CI 0.18-0.39) of unfavourable treatment outcome.  The proportion of MDR-TB patients reaching favourable treatment outcome in Armenia was substantially lower than the recommended level (75%). The most common treatment outcome was LTFU indicating the need for further assessment of underlying determinants. Home-based treatment looks promising and future studies are required to see if expanding it to all RR/MDR-TB patients is feasible and cost-effective.

Effectiveness and safety of delamanid- or bedaquiline-containing regimens among children and adolescents with multidrug resistant or extensively drug resistant tuberculosis: A nationwide study from Belarus, 2015-19.

There is limited evidence describing the safety and effectiveness of bedaquiline and delamanid containing regimens in children and adolescents with Multidrug-Resistant Tuberculosis (MDR-TB) and Extensively Drug-Resistant Tuberculosis (XDR-TB) globally. In this nationwide descriptive cohort study from Belarus, we examined adverse drug events, time to culture conversion, treatment outcomes including post-treatment recurrence among children and adolescents (<18 years of age) treated with bedaquiline and/or delamanid containing regimens from 2015 to 2019. Of the 40 participants included (55% females; age range 10-17 years), 20 (50%) had XDR-TB and 15 (38%) had resistance to either fluoroquinolone or second-line injectable. Half of the patients received delamanid and another half received bedaquiline with one patient receiving both drugs. AEs were reported in all the patients. A total of 224 AEs were reported, most of which (76%) were mild in nature. Only 10 (5%) AEs were graded severe and one AE was graded life-threatening. A total of 7 AEs (3%) were classified as 'serious' and only one patient required permanent discontinuation of the suspected drug (linezolid). Most of the AEs (94%) were resolved before the end of treatment. All patients culture-positive at baseline (n=34) became culture-negative within three months of treatment. Median time to culture conversion was 1.1 months (interquartile range: 0.9-1.6). Two patients were still receiving treatment at the time of analysis. The remaining 38 patients successfully completed treatment. Among those eligible and assessed at 6 (n=32) and 12 months (n=27) post-treatment, no recurrences were detected. In conclusion, treatment of children and adolescents with MDR-TB and XDR-TB using bedaquiline and/or delamanid containing regimens was effective and had favourable safety profile. Achieving such excellent outcomes under programmatic settings is encouraging for other national tuberculosis programmes, which are in the process of introducing or scaling-up the use of these new drugs in their countries.

Initiation of antiretroviral therapy or antiretroviral prophylaxis in pregnant women living with HIV registered in five townships of Mandalay, Myanmar: A cross sectional study.

BACKGROUND: A series of interventions are required to prevent mother to child transmission (PMTCT) of Human Immunodeficiency Virus (HIV) starting from HIV testing of pregnant women, initiating antiretroviral therapy (ART) or antiretroviral prophylaxis to HIV-positive pregnant women to providing HIV prophylaxis to newborn babies. Gaps in each step can significantly affect the effectiveness of PMTCT interventions. We aimed to determine the gap in initiation of ART/antiretroviral prophylaxis for pregnant women living with HIV, delay in initiation of ART/antiretroviral prophylaxis and factors associated with the delay. METHODS: This is a cross sectional study using routinely collected programme data from five health facilities providing PMTCT services located at Township Health Departments (THD) of Mandalay, Myanmar. RESULTS: There were 363 pregnant women living with HIV enrolled between January 2012 and December 2017. Sixty (16%) women were excluded from the study due to missing data on dates of HIV diagnosis. Of 303 (84%) women included in the study, 89/303 (29%) and 214/303 (71%) were diagnosed with HIV before and during current pregnancy respectively. Among 214 women, 180 (84%) women were started on ART by the censor date (31st March 2018). Among those who started ART, 109 (61%) women had a delay of starting ART > 2 weeks from diagnosis. Women residing in township 4 had a significantly higher risk of delay in initiation of ART/antiretroviral prophylaxis compared to women residing in township 1 [adjusted prevalence ratio 4.2 (95% confidence interval 1.2-14.8]. CONCLUSIONS: We found that one in four women living with HIV knew their HIV status before current pregnancy. Although the rate of ART/antiretroviral prophylaxis initiation was high among pregnant women living with HIV, there was a delay. Early initiation of ART/antiretroviral prophylaxis among newly HIV diagnosed pregnant women needs to be strengthened.

Uptake of antiretroviral therapy in HIV-positive women ever enrolled into 'prevention of mother to child transmission' programme, Mandalay, Myanmar-a cohort study.

BACKGROUND: Early initiation and longer duration of anti-retroviral therapy either as prophylaxis (pARV) or lifelong treatment (ART) in HIV-positive pregnant women prior to delivery has a huge impact in reducing mother to child transmission (MTCT) of HIV, maternal morbidity, mortality and increasing retention in care. In this study, we aimed to determine the following in a 'prevention of mother-to-child transmission' (PMTCT) programme in Central Women Hospital, Mandalay, Myanmar: i) uptake of ART and factors associated with the uptake ii) duration of ART/ pARV received by HIV-positive pregnant women prior to delivery, iii) factors associated with ART/ pARV initiation after delivery and iv) factors associated with shorter duration of ART/ pARV (≤ 8 weeks prior to delivery). METHOD: This was a retrospective cohort study using routinely collected data from PMTCT programme. We used multivariable Cox proportional Hazard model or log binomial models to assess the association between socio-demographic and clinical factors with a) uptake of ART/pARV, b) initiation of ART/pARV after delivery, c) shorter (≤8 weeks) duration of ART/PARV prior to delivery. RESULTS: Of the 670 ART naïve HIV-positive women enrolled to PMTCT programme between March 2011 and December 2016, 588 (88%) were initiated on ART/pARV. In adjusted analysis, only pregnancy stage at enrolment was significantly associated with initiation of ART/pARV. Of 585 who had delivered babies on or before the censor date, 522 (89%) were on ART/pARV. Women who lived outside Mandalay were more likely to be initiated on ART after delivery (i.e., delayed ART initiation in those on ART). Among women who were initiated on ART/pARV before delivery (n = 468), only 59% got ART/pARV for > 8 weeks before delivery. Women whose spouses' HIV status was not recorded had 40% higher risk of short duration of ART/pARV. CONCLUSIONS: This study shows high uptake of ART/pARV among those enrolled into the PMTCT programme. However, about one in eight pregnant women did not receive ART before delivery. Among those initiated on ART/pARV before delivery, nearly half of them received ART/pARV for less than 8 weeks prior to delivery. These aspects need to be improved in order to eliminate mother-to-child transmission of HIV.

Using mobile phones to ensure that referred tuberculosis patients reach their treatment facilities: a call that makes a difference.

BACKGROUND: Over the last decade, the availability and use of mobile phones have grown exponentially globally and in Cambodia. In the Sihanouk Hospital Centre of Hope(SHCH) in Cambodia about half of all tuberculosis patients referred out to peripheral health facilities for TB treatment initiation or continuation were lost to contact after referral ranging from 19 to 69% between 2008 and 2013. To address this, we implemented a mobile phone-based patient tracking intervention. Here, we report the number and proportion of referred TB patients who could be contacted through a mobile phone and retained in care after the introduction of mobile phone tracking. METHODS: A descriptive study involving follow-up of TB patients referred out from SHCH to peripheral health facilities during May-October 2014. Standard operating procedures were used to contact individual patients and/or health facilities using a mobile phone. RESULTS: Among 109 TB patients referred to peripheral health facilities, 107(98%) had access to a mobile phone of whom, 103(97%) could be contacted directly while 5(2%) were contacted through their health care providers. A total of 108(99%) of 109 referred TB patients in intervention period were thus placed on TB treatment. CONCLUSIONS: This study provides preliminary, but promising evidence that using mobile phones was accompanied with improved retention of referred TB patients compared to historical cohorts. Given the limitations associated with historical controls, we need better designed studies with larger sample size to strengthen the evidence before national scale-up.

Measuring and understanding motivation among community health workers in rural health facilities in India-a mixed method study.

BACKGROUND: Motivated human resource is the key to improve health system performance and retention of health workers. There is scanty literature on measuring motivation of health workers in India. Thus, the objective of this study was to measure and identify important aspects of health workers' motivation in North India. METHODS: A mixed method study design was adopted. Under the quantitative component, we interviewed randomly selected 62 community health workers (CHWs) in 18 sub-centres in two blocks of District Ambala, Haryana, India using a structured motivation scale. In-depth interviews were also carried out with 18 CHWs to explore the sources of motivation. RESULTS: The age of respondents and training in the past 12 months were found to be significantly associated with motivation. Job burnout, poor personal health, job insecurity and less career development opportunities were the individual level de-motivators, whereas not being able to fulfil family roles and poor supportive supervision were identified as environmental factors for poor motivation. Love for work, and financial incentives were individual level motivators, while community support and recognition, organizational commitment and pride, regular training were identified as environmental level motivators. CONCLUSION: Non-financial motivators such as interpersonal relations, family support, skill and career development opportunities require more attention. Regular need-based training is essential to maintain high levels of motivation.

Is adjunctive naturopathy associated with improved glycaemic control and a reduction in need for medications among type 2 Diabetes patients? A prospective cohort study from India.

BACKGROUND: With an estimated 65 million Diabetes Mellitus (DM) patients, India ranks second in the world in terms of DM burden. The emphasis of current medical practice has been on pharmacotherapy but, despite the best combination therapies, acheiving glycaemic control (reduction of blood sugar to desirable levels) is a challenge. 'Integrated Naturopathy and Yoga'(INY) is an alternative system of medicine that lays emphasis on the role of diet and physical exercise. We assessed the short term effect of INY as an adjunct to pharmacotherapy on glycaemic control among type 2 DM patients. METHODS: In this prospective cohort study with a 3 month follow-up, DM patients consecutively admitted to a hospital in India from May-October 2014 for either 15 or 30 days were offered INY - a package of vegetarian diet with no added oil, sugar and salt, yoga-based exercise, patient counselling and rest. A 'favourable outcome' was defined as glycaemic control (glycosylated hemoglobin (HbA1c) < 7 % or absolute reduction by 1 %) along with at least 50 % reduction in antidiabetes medication at 3 months relative to baseline. Compliance to diet was scored by self-report on a scale of 0-10 and categorized into poor (0-5), moderate (6-8) and excellent (9-10). RESULTS: Of 101 patients with 3-month follow-up data, 65(65 %) achieved a favourable outcome - with 19(19 %) stopping medication while sustaining glycemic control. Factors associated with favourable outcome were baseline HbA1c and compliance to diet, which showed a significant linear relationship with mean HbA1c reductions of 0.4 %, 1.1 % and 1.7 % in relation to poor, moderate and excellent dietary compliance respectively. CONCLUSION: INY, adjunctive to pharmacotherapy, was associated with a significant beneficial effect on glycaemic control and reduced the overall need for antidiabetes medications. These early results are promising. Further studies with long-term follow-up and using more rigorous randomized controlled trial designs are needed.

A first country-wide review of Diabetes Mellitus care in Bhutan: time to do better.

BACKGROUND: There is an increasing trend of non-communicable diseases in Bhutan including Diabetes Mellitus (DM). To address this problem, a National Diabetes Control Programme was launched in 1996. There is anecdotal evidence that many patients do not visit the DM clinics regularly, but owing to lack of cohort monitoring, the magnitude of such attrition from care is unknown. Knowledge of the extent of this problem will provide a realistic assessment of the situation on the ground and would be helpful to initiate corrective actions. In this first country-wide audit, we thus aimed to determine among type 2 DM patients registered for care the i) pre-treatment attrition ii) one-year programme outcomes including retention in care, died and Lost-to-follow-up (LTFU, defined as not having visited the clinic at least once within a year of registration) iii) factors associated with attrition from care (death + LTFU) and iv) quality of follow-up care, measured by adherence to recommended patient-monitoring protocols including glycaemic control. METHODS: A retrospective cohort study involving a review of records routinely maintained under the National Diabetes Control Programme. All type 2 DM patients registered between 1st January and 31st December 2012 in 18 district hospitals of Bhutan were included. Glycaemic control was defined as glycosylated haemoglobin of <7% or [Fasting Blood Sugar of <130 mg/dl and, Post-prandial Blood Sugar of <180 mg/dl]. RESULTS: Of 350 registered DM patients (52% female, median age 55 years), 63(18%) were LTFU before treatment initiation (pre-treatment attrition). Of the remaining 287 individuals who started treatment, 226(79%) were retained in care while 61(21%) either died or were LTFU. Glycaemic control was achieved in 85(38%) patients retained in care. Between 7 and 98% of monitoring parameters had missing data. CONCLUSION: Nearly one-third of DM patients were LTFU and there were short comings in monitoring. Qualitative research is urgently needed to find out the reasons for high attrition. Given the high political commitment by the Royal Government of Bhutan, the findings provide ample grounds for instituting corrective measures and propelling DM care further. It is time to do better!

Neonatal mortality in India's rural poor: Findings of a household survey and verbal autopsy study in Rajasthan, Bihar and Odisha.

In 2011, Save the Children India launched a project for the disadvantaged population of Rajasthan, Bihar and Odisha. As a baseline activity, neonatal deaths during January-December 2012 were investigated using modified verbal autopsy tool in six sub-district-level administrative units (blocks) adopting 30-cluster sample survey approach. Our study reported a total of 189 neonatal deaths of which 50% occurred at home and 39% happened on Day 1. About half of the deaths occurred in blocks from Bihar. High number of neonatal deaths belonged to households that were below poverty line (64%) and other disadvantaged classes (46%); among mothers who were illiterate (65%), <20 years of age (54%) and during their first-order births (36%). Birth asphyxia was a major cause of neonatal deaths across all blocks. These findings indicate need for easy and early access to transport services, specialized neonatal care and advocacy targeted towards increasing community awareness.

Research to policy and practice change: is capacity building in operational research delivering the goods?

OBJECTIVES: Between 2009 and 2012, eight operational research capacity building courses were completed in Paris (3), Luxembourg (1), India (1), Nepal (1), Kenya (1) and Fiji (1). Courses had strict milestones that were subsequently adopted by the Structured Operational Research and Training InitiaTive (SORT IT) of the World Health Organization. We report on the numbers of enrolled participants who successfully completed courses, the number of papers published and their reported effect on policy and/or practice. DESIGN: Retrospective cohort study including a survey. METHODS: Participant selection criteria ensured that only those proposing specific programme-related and relevant operational research questions were selected. Effects on policy and/or practice were assessed in a standardised manner by two independent reviewers. RESULTS: Of 93 enrolled participants from 31 countries (14 in Africa, 13 in Asia, two in Latin America and two in South Pacific), 83 (89%) completed their courses. A total of 96 papers were submitted to scientific journals of which 89 (93%) were published and 88 assessed for effect on policy and practice. There was a reported effect in 65 (74%) studies including changes to programme implementation (27), adaptation of monitoring tools (24) and changes to existing guidelines (20). CONCLUSION: Three quarters of published operational research studies from these structured courses had reported effects on policy and/or practice. It is important that this type of tracking becomes a standard component of operational research and research in general.

"Together against Tuberculosis": Cascade of Care of Patients Referred by the Private Health Care Providers in the Kyrgyz Republic.

Until 2021, in the Kyrgyz Republic, tuberculosis (TB) was diagnosed and treated only in the public sector. With funding support of the STOP-TB partnership, the private providers in four regions of the country and Bishkek city were mapped, trained and incentivized to screen for and identify presumptive TB patients and refer them to the public facilities for diagnosis and treatment. In this study, we describe the cascade of care of such patients. This was a cohort study involving secondary analysis of routine data. Of 79,352 patients screened during February 2021-March 2022, 2511 (3%) had presumptive TB, of whom 903 (36%) were not tested for TB [pre-diagnostic loss to follow-up]. A total of 323 (13%) patients were diagnosed with TB, of whom, 42 (13%) were not started on treatment [pre-treatment loss to follow-up]. Among 257 patients eligible for outcome assessment, 197 (77%) had treatment success, 29 (11%) were lost-to-follow-up, 13 (5%) died, 4 (2%) had treatment failure and 14 (5%) were not evaluated. While this donor-funded, pioneering initiative was successful in engaging the private sector, we recommend that the national TB programme scales up the initiative nationally with dedicated budgets, activities and plans to monitor progress. Qualitative research is urgently needed to understand the reasons for the gaps in the care cascade.

Empanelment of the Population to the Primary Medical Care Institution of Sri Lanka: A Mixed-Methods Study on Outcomes and Challenges.

The registration of individuals with designated primary medical care institutions (PMCIs) is a key step towards their empanelment with these PMCIs, supported by the Primary Health Care System Strengthening Project in Sri Lanka. We conducted an explanatory mixed-methods study to assess the extent of registration at nine selected PMCIs and understand the challenges therein. By June 2021, 36,999 (19.2%, 95% CI-19.0-19.4%) of the 192,358 catchment population allotted to these PMCIs were registered. At this rate, only 50% coverage would be achieved by the end of the project (December 2023). Proportions of those aged <35 years and males among those registered were lower compared to their general population distribution. Awareness activities regarding registration were conducted in most of the PMCIs, but awareness in the community was low. Poor registration coverage was due to a lack of dedicated staff for registration, misconceptions of health care workers about individuals needing to be registered, reliance on opportunistic or passive registration, and lack of monitoring mechanisms; these were further compounded by the COVID-19 pandemic. Moving forward, there is an urgent need to address these challenges to improve registration coverage and ensure that all individuals are empaneled before the close of the project for it to have a meaningful impact.

Increased All-cause Mortality in People With HIV and Comorbidities: Hepatitis B and C Virus Seropositivity and Hyperglycemia in Myanmar, 2005-2017.

Background: Hepatitis C virus (HCV) and hepatitis B virus (HBV) coinfection are associated with increased mortality in people with HIV (PWH), and hyperglycemia is a common comorbidity in PWH. In this study, we used routinely collected clinical data to assess the associations between HBV and HCV seropositivity with all-cause mortality and whether this relationship differs by hyperglycemia status. Methods: Eligible participants included adult PWH (≥15 years) who initiated antiretroviral therapy between May 2005 and June 2016 in Myanmar. HBV and HCV serostatus and hyperglycemia were measured at enrollment to HIV care using HBV surface antigen, HCV antibody tests, and random blood glucose (≥140 mg/dL), respectively. Results: Among 27 722 PWH, 2260 (8%) were HBV seropositive, 2265 (9%) were HCV seropositive, 178 (0.6%) were HBV-HCV seropositive, and 1425 (5%) had hyperglycemia. During the median follow-up (interquartile range) of 3.1 (1.5-5.1) years, 3655 (13%) PWH died, and the overall mortality rate was 3.8 (95% CI, 3.7-3.9) per 100-person-years (PY). The mortality rate (per 100 PY) among PWH who were HBV seropositive was 4.6, among PWH who were HCV seropositive it was 5.1, and among PWH who were HBV-HCV seropositive it was 7.1. When stratified by glycemic status, the mortality rate was higher among patients with hyperglycemia compared with those with euglycemia (5.4 vs 4.0 per 100 PY), and the difference in mortality rate between patients with hyperglycemia and euglycemia was highest among those with HCV seropositivity (9.8 vs 5.0 per 100 PY). Conclusions: Increased mortality rates associated with HBV and HCV seropositivity in PWH differed by their glycemic status. PWH with HCV seropositivity and hyperglycemia had the highest mortality rates.

Outcomes and Challenges in Noncommunicable Disease Care Provision in Health Facilities Supported by Primary Health Care System Strengthening Project in Sri Lanka: A Mixed-Methods Study.

The Primary Healthcare System Strengthening Project in Sri Lanka focuses on improving noncommunicable disease (NCD) care provision at primary medical care institutions (PMCIs). We conducted an explanatory mixed-methods study to assess completeness of screening for NCD risk, linkage to care, and outcomes of diabetes/hypertension care at nine selected PMCIs, as well as to understand reasons for gaps. Against a screening coverage target of 50% among individuals aged ≥ 35 years, PMCIs achieved 23.3% (95% CI: 23.0-23.6%) because of a lack of perceived need for screening among the public and COVID-19-related service disruptions. Results of investigations and details of further referral were not documented in almost half of those screened. Post screening, 45% of those eligible for follow-up NCD care were registered at medical clinics. Lack of robust recording/tracking mechanisms and preference for private providers contributed to post-screening attrition. Follow-up biochemical investigations for monitoring complications were not conducted in more than 50% of diabetes/hypertension patients due to nonprescription of investigations by healthcare providers and poor uptake among patients because of nonavailability of investigations at PMCI, requiring them to avail services from the private sector, incurring out-of-pocket expenditure. Primary care strengthening needs to address these challenges to ensure successful integration of NCD care within PMCIs.

Feasibility, enablers and challenges of using timeliness metrics for household contact tracing and TB preventive therapy in Pakistan.

INTRODUCTION: Screening household contacts of TB patients and providing TB preventive therapy (TPT) is a key intervention to end the TB epidemic. Global and timely implementation of TPT in household contacts, however, is dismal. We adapted the 7-1-7 timeliness metric designed to evaluate and respond to infectious disease outbreaks or pandemics, and assessed the feasibility, enablers and challenges of implementing this metric for screening and management of household contacts of index patients with bacteriologically-confirmed pulmonary TB in Karachi city, Pakistan. METHODS: We conducted an explanatory mixed methods study with a quantitative component (cohort design) followed by a qualitative component (descriptive design with focus group discussions). RESULTS: From January-June 2023, 92% of 450 index patients had their household contacts line-listed within seven days of initiating anti-TB treatment ("first 7"). In 84% of 1342 household contacts, screening outcomes were ascertained within one day of line-listing ("next 1"). In 35% of 256 household contacts eligible for further evaluation by a medical officer (aged ≤5 years or with chest symptoms), anti-tuberculosis treatment, TPT or a decision for no drugs was made within seven days of symptom screening ("second 7"). The principal reason for not starting anti-tuberculosis treatment or TPT was failure to consult a medical officer: only 129(50%) of 256 contacts consulted a medical officer. Reasons for poor performance in the "second 7" component included travel costs to see a medical officer, loss of daily earnings and fear of a TB diagnosis. Field staff reported that timeliness metrics motivated them to take prompt action in household contact screening and TPT provision and they suggested these be included in national guidelines. CONCLUSIONS: Field staff found "7-1-7" timeliness metrics to be feasible and useful. Integration of these metrics into national guidelines could improve timeliness of diagnosis, treatment and prevention of TB within households of index patients.

Improvement in Infection Prevention and Control Compliance at the Three Tertiary Hospitals of Sierra Leone following an Operational Research Study.

Implementing infection prevention and control (IPC) programmes in line with the World Health Organization's (WHO) eight core components has been challenging in Sierra Leone. In 2021, a baseline study found that IPC compliance in three tertiary hospitals was sub-optimal. We aimed to measure the change in IPC compliance and describe recommended actions at these hospitals in 2023. This was a 'before and after' observational study using two routine cross-sectional assessments of IPC compliance using the WHO IPC Assessment Framework tool. IPC compliance was graded as inadequate (0-200), basic (201-400), intermediate (401-600), and advanced (601-800). The overall compliance scores for each hospital showed an improvement from 'Basic' in 2021 to 'Intermediate' in 2023, with a percentage increase in scores of 16.9%, 18.7%, and 26.9% in these hospitals. There was improved compliance in all core components, with the majority in the 'Intermediate' level for each hospital IPC programme. Recommended actions including the training of healthcare workers and revision of IPC guidelines were undertaken, but a dedicated IPC budget and healthcare-associated infection surveillance remained as gaps in 2023. Operational research is valuable in monitoring and improving IPC programme implementation. To reach the 'Advanced' level, these hospitals should establish a dedicated IPC budget and develop long-term implementation plans.

Managing Comorbidities, Determinants and Disability at Start and End of TB Treatment under Routine Program Conditions in China.

Many patients with tuberculosis (TB) have comorbidities, risk determinants and disability that co-exist at diagnosis, during and after TB treatment. We conducted an observational cohort study in 11 health facilities in China to assess under routine program conditions (i) the burden of these problems at the start and end of TB treatment and (ii) whether referral mechanisms for further care were functional. There were 603 patients registered with drug-susceptible TB who started TB treatment: 84% were symptomatic, 14% had diabetes, 14% had high blood pressure, 19% smoked cigarettes, 10% drank excess alcohol and in 45% the 6 min walking test (6MWT) was abnormal. Five patients were identified with mental health disorders. There were 586 (97%) patients who successfully completed TB treatment six months later. Of these, 18% were still symptomatic, 12% had diabetes (the remainder with diabetes failed to complete treatment), 5% had high blood pressure, 5% smoked cigarettes, 1% drank excess alcohol and 25% had an abnormal 6MWT. Referral mechanisms for the care of comorbidities and determinants worked well except for mental health and pulmonary rehabilitation for disability. There is need for more programmatic-related studies in other countries to build the evidence base for care of TB-related conditions and disability.
