Quality of life in people living with HIV in Aotearoa New Zealand: an exploratory cross-sectional study.

Quality of life (QoL) in people living with HIV (PLHIV) is reportedly worse than in people without HIV, with many factors impacting on this. We aimed to investigate QoL in PLHIV in New Zealand (NZ). In-person interviews were conducted including socio-demographic, health, social connectedness, and stigma-related questions. QoL was measured using the 13-question PozQoL Scale - summed to give a score between 13 and 65. Univariate linear regression was used to investigate factors associated with differences in PozQoL scores. PLHIV (n = 188) of different ethnicities from throughout NZ participated. The mean age was 47 years; 65% were men; 61% were men who have sex with men; 61% had been living with HIV for ≥10 years. The mean summary PozQoL score was 47.16. Factors associated with a lower mean PozQol included no sex in the last 12 months (-9.03), inability to meet basic needs (-7.47), ever (-6.49) or recently (-5.03), experiencing stigma or discrimination, mental health condition (-5.74), HIV diagnosis <5 years (-5.48), poor health (-5.43), being unemployed (-5.02), not having support (-4.71), and greater internalised stigma (-2.81). Improving QoL will require investment in peer support and community welfare programmes to better support PLHIV, and stigma reduction campaigns targeting the broader community.

Population rates of HIV, gonorrhoea and syphilis diagnoses by sexual orientation in New Zealand.

INTRODUCTION: Globally, gay and bisexual men (GBM) are over-represented in HIV, syphilis and gonorrhoea cases. However, surveillance systems rarely provide meaningful measures of inequity, such as population-specific rates, due to a lack of sexual orientation denominators. HIV, gonorrhoea and syphilis are legally notifiable diseases in New Zealand (NZ); we calculate rates by sexual orientation for the first time. METHODS: We analysed 2019 national surveillance data on HIV, syphilis and gonorrhoea notifications disaggregated by sexual orientation. Unique health records identified duplicate notifications and reinfections. Missing data were imputed from known cases. We used the NZ Health Survey 2014/2015 to estimate population sizes by sexual orientation, measured in two ways (current sexual identity, sexual contact in the previous 12 months with men, women or both). We calculated notification rates per 100 000 for each sexual orientation subgroup and rate ratios. RESULTS: In 2019, GBM accounted for 76.3%, 65.7% and 39.4% of HIV, syphilis and gonorrhoea notifications, respectively. Population rates per 100 000 for HIV were 158.3 (gay/bisexual men) and 0.5 (heterosexuals); for syphilis, population rates per 100 000 were 1231.1 (gay/bisexual men), 5.0 (lesbian/bisexual women) and 7.6 (heterosexuals); for gonorrhoea (imputed), population rates per 100 000 were 6843.2 (gay/bisexual men), 225.1 (lesbian/bisexual women) and 120.9 (heterosexuals). The rate ratios for GBM compared with heterosexuals were: 348.3 (HIV); 162.7 (syphilis); and 56.6 (gonorrhoea). Inequities remained in sensitivity analysis (substituting sexual identity with sexual behaviour in the previous 12 months). CONCLUSION: GBM in NZ experience profound inequities in HIV, syphilis and gonorrhoea. Rate ratios by sexual orientation provide useful 'at-a-glance' measures of inequity in disease incidence.

Cost analysis and critical success factors of the use of oxygen concentrators versus cylinders in sub-divisional hospitals in Fiji.

BACKGROUND: Oxygen is vital in the treatment of illnesses in children and adults, yet is lacking in many low and middle-income countries health care settings. Oxygen concentrators (OCs) can increase access to oxygen, compared to conventional oxygen cylinders. We investigated the costs and critical success factors of OCs in three hospitals in Fiji, and extrapolated these to estimate the oxygen delivery cost to all Sub-Divisional hospitals (SDH) nationwide. METHODS: Data sources included key personnel interviews, and data from SDH records, Ministry of Health and Medical Services, and a non-governmental organisation. We used Investment Logic Mapping (ILM) to define key issues. An economic case was developed to identify the investment option that optimised value while incorporating critical success factors identified through ILM. A fit-for-purpose analysis was conducted using cost analysis of four short-listed options. Sensitivity analyses were performed by altering variables to show the best or worst case scenario. All costs are presented in Fijian dollars. RESULTS: Critical success factors identifed included oxygen availability, safety, ease of use, feasibility, and affordability. Compared to the status quo of having only oxygen cylinders, an option of having a minimum number of concentrators with cylinder backup would cost $434,032 (range: $327,940 to $506,920) over 5 years which would be 55% (range: 41 to 64%) of the status quo cost. CONCLUSION: Introducing OCs into all SDHs in Fiji would reduce overall costs, while ensuring identified critical success factors are maintained. This study provides evidence for the benefits of OCs in this and similar settings.

Latent tuberculosis infection in healthcare workers in low- and middle-income countries: an updated systematic review.

Healthcare workers (HCWs) are at increased risk of latent tuberculosis (TB) infection (LTBI) and TB disease.We conducted an updated systematic review of the prevalence and incidence of LTBI in HCWs in low- and middle-income countries (LMICs), associated factors, and infection control practices. We searched MEDLINE, Embase and Web of Science (January 1, 2005-June 20, 2017) for studies published in any language. We obtained pooled estimates using random effects methods and investigated heterogeneity using meta-regression.85 studies (32 630 subjects) were included from 26 LMICs. Prevalence of a positive tuberculin skin test (TST) was 14-98% (mean 49%); prevalence of a positive interferon-γ release assay (IGRA) was 9-86% (mean 39%). Countries with TB incidence ≥300 per 100 000 had the highest prevalence (TST: pooled estimate 55%, 95% CI 41-69%; IGRA: pooled estimate 56%, 95% CI 39-73%). Annual incidence estimated from the TST was 1-38% (mean 17%); annual incidence estimated from the IGRA was 10-30% (mean 18%). The prevalence and incidence of a positive test was associated with years of work, work location, TB contact and job category. Only 15 studies reported on infection control measures in healthcare facilities, with limited implementation.HCWs in LMICs in high TB incidence settings remain at increased risk of acquiring LTBI. There is an urgent need for robust implementation of infection control measures.

Corrigendum to: Enumerating the population eligible for funded HIV pre-exposure prophylaxis (PrEP) in New Zealand.

Background:Pre-exposure prophylaxis (PrEP) became publicly funded in New Zealand (NZ) on 1 March 2018. PrEP could have a substantial population-level effect on HIV transmission if scaled up rapidly. An accurate estimate of the size of the PrEP-eligible population would guide implementation. Methods: We drew on nine sources to estimate the PrEP-eligible population, namely Statistics NZ data, Pharmaceutical Management Agency (PHARMAC) data on adults receiving funded antiretroviral treatment (ART), expert advice, estimates of the HIV care cascade, surveillance of undiagnosed HIV in a community sample of gay and bisexual men (GBM), surveillance of HIV diagnoses, NZ Health Survey data on sexual orientation among males, behavioural surveillance among GBM and behavioural data among people living with HIV (PLWH) from the HIV Futures NZ study. From these sources we derived three estimates relating to GBM, non-GBM and total eligible population. Sensitivity analyses examined different assumptions (GBM denominators, proportion PLWH diagnosed, proportion of diagnosed PLWH treated). Results: We estimated that 17.9% of sexually active HIV-negative GBM would be eligible for PrEP, equating to 5816 individuals. We estimated that 31 non-GBM individuals would be eligible for PrEP. Thus, in total, 5847 individuals would be eligible for PrEP, comprising 99.5% GBM and 0.5% non-GBM. Sensitivity analyses ranged from 3062 to 6718 individuals. Conclusions: Policy makers can use enumeration to monitor the speed and scale in coverage as implementation of publicly funded PrEP proceeds. Sexual health and primary care services can use enumeration to forecast PrEP demand and plan accordingly. Better quality data, especially on transgender adults in NZ, would improve the accuracy of estimates.

Accuracy of diabetes screening methods used for people with tuberculosis, Indonesia, Peru, Romania, South Africa.

OBJECTIVE: To evaluate the performance of diagnostic tools for diabetes mellitus, including laboratory methods and clinical risk scores, in newly-diagnosed pulmonary tuberculosis patients from four middle-income countries. METHODS: In a multicentre, prospective study, we recruited 2185 patients with pulmonary tuberculosis from sites in Indonesia, Peru, Romania and South Africa from January 2014 to September 2016. Using laboratory-measured glycated haemoglobin (HbA1c) as the gold standard, we measured the diagnostic accuracy of random plasma glucose, point-of-care HbA1c, fasting blood glucose, urine dipstick, published and newly derived diabetes mellitus risk scores and anthropometric measurements. We also analysed combinations of tests, including a two-step test using point-of-care HbA1cwhen initial random plasma glucose was ≥ 6.1 mmol/L. FINDINGS: The overall crude prevalence of diabetes mellitus among newly diagnosed tuberculosis patients was 283/2185 (13.0%; 95% confidence interval, CI: 11.6-14.4). The marker with the best diagnostic accuracy was point-of-care HbA1c (area under receiver operating characteristic curve: 0.81; 95% CI: 0.75-0.86). A risk score derived using age, point-of-care HbA1c and random plasma glucose had the best overall diagnostic accuracy (area under curve: 0.85; 95% CI: 0.81-0.90). There was substantial heterogeneity between sites for all markers, but the two-step combination test performed well in Indonesia and Peru. CONCLUSION: Random plasma glucose followed by point-of-care HbA1c testing can accurately diagnose diabetes in tuberculosis patients, particularly those with substantial hyperglycaemia, while reducing the need for more expensive point-of-care HbA1c testing. Risk scores with or without biochemical data may be useful but require validation.

Disease characteristics and treatment of patients with diabetes mellitus attending government health services in Indonesia, Peru, Romania and South Africa.

OBJECTIVE: To describe the characteristics and management of Diabetes mellitus (DM) patients from low- and middle-income countries (LMIC). METHODS: We systematically characterised consecutive DM patients attending public health services in urban settings in Indonesia, Peru, Romania and South Africa, collecting data on DM treatment history, complications, drug treatment, obesity, HbA1c and cardiovascular risk profile; and assessing treatment gaps against relevant national guidelines. RESULTS: Patients (median 59 years, 62.9% female) mostly had type 2 diabetes (96%), half for >5 years (48.6%). Obesity (45.5%) and central obesity (females 84.8%; males 62.7%) were common. The median HbA1c was 8.7% (72 mmol/mol), ranging from 7.7% (61 mmol/mol; Peru) to 10.4% (90 mmol/mol; South Africa). Antidiabetes treatment included metformin (62.6%), insulin (37.8%), and other oral glucose-lowering drugs (34.8%). Disease complications included eyesight problems (50.4%), EGFR <60 ml/min (18.9%), heart disease (16.5%) and proteinuria (14.7%). Many had an elevated cardiovascular risk with elevated blood pressure (36%), LDL (71.0%) and smoking (13%), but few were taking antihypertensive drugs (47.1%), statins (28.5%) and aspirin (30.0%) when indicated. Few patients on insulin (8.0%), statins (8.4%) and antihypertensives (39.5%) reached treatment targets according to national guidelines. There were large differences between countries in terms of disease profile and medication use. CONCLUSION: DM patients in government clinics in four LMIC with considerable growth of DM have insufficient glycaemic control, frequent macrovascular and other complications, and insufficient preventive measures for cardiovascular disease. These findings underline the need to identify treatment barriers and secure optimal DM care in such settings.

The Bandung neurosurgery patient outcomes project, Indonesia (Part I): Methods, participant characteristics, and pre-discharge outcomes.

INTRODUCTION: Little is known about neurosurgery patient outcomes in Indonesia. Our study sought to describe patient characteristics, health care pathways, health-related quality of life, and health/rehabilitation care needs of patients admitted to, and discharged from, a major neurosurgery department. METHODS: Eligible patients were aged ≥18 years admitted to the Neurosurgery Department in a regional referral hospital in Bandung, Indonesia. Baseline data was collected on admission. An in-person interview (in the Indonesian language) was held 1 to 2 days pre-discharge. Sociodemographic along with clinical characteristics, Glasgow Coma Scale (GCS), and EQ-5D-5L data were collected. RESULTS: A total of 217 patients were admitted, 37 died before discharge, and a pre-discharge interview was undertaken by 178 (82%). Almost half (48%) were admitted because of injury, 38% brain tumour, 10% acute illness, and 4% other conditions. The mean age was 41 years. On admission, 63% had a mild Glasgow Coma Scale, 31% moderate, and 3% severe. The average hospital stay was 8 days for injury and 24 days for illness patients. Prior to discharge, one-third, or less, of the 178 patients interviewed reported "no problems" in the EQ-5D dimensions of mobility (32%), self-care (27%), usual activities (16%), and pain/discomfort (32%), whereas 70% reported "no problems" with anxiety/depression. CONCLUSION: A large proportion of patients are being discharged with considerable levels of difficulty in four of the five EQ-5D dimensions. This stresses the importance of providing good follow-up and support of patients and their families.

The Bandung neurosurgery patient outcomes project, Indonesia (Part II): Patient pathways and feasibility and acceptability of telephone follow-up.

INTRODUCTION: Support of neurosurgery patients following discharge from hospital is important. Currently, little is known about patients' in low- and middle-income countries before and after their hospital treatment. This companion paper reports patients' pathways before and after hospital admission and the feasibility of following up this ill-patient population by telephone. METHODS: Eligible patients were aged ≥18 years admitted to the Neurosurgery Department in Dr. Hasan Sadikin Hospital-a regional referral hospital in Bandung City, Indonesia. Clinical data were collected on admission by clinicians. In-person interviews were undertaken with a clinical research nurse 1 to 2 days pre-discharge, and telephone follow-up interviews at 1, 2, and 3 months post-discharge. Information was also collected on pathways prior to admission and following discharge. The number of contact attempts for each patient interview was documented, as was the overall acceptability of undertaking a telephone interview. RESULTS: Of 178 patients discharged from hospital, 12 later died. Of the remaining 166 patients, 95% were able to be followed up to 3 months. Two-thirds of patients had been referred from another hospital. Patients came from, and were discharged to, locations throughout the West Java region. At the 1-month interview, 84% participants reported that they had had a follow-up consultation with a health professional-mostly with a neurosurgeon. CONCLUSION: This study has shown that, with a neurosurgery nurse delegated to the role, it is feasible to conduct follow-up telephone interviews with patients after discharge from a neurosurgery ward and that in fact such follow-up was appreciated by patients.

Tuberculosis care provided by private practitioners in an urban setting in Indonesia: Findings from a standardized patient study.

In Indonesia, government-owned Community Health Centers (CHCs) spearhead tuberculosis (TB) care at the primary level, but a substantial proportion of individuals with pulmonary TB also seek care from Private Practitioners (PPs). However, little is known about PPs' practice in managing patients with TB-associated symptoms. To avoid bias associated with self-administered surveys, we used standardized patients (SPs) to evaluate PPs' adherence to the national TB guidelines. Four clinical scenarios of individuals presenting complaints suggestive of TB, accompanied by different sputum smear results or TB treatment histories were developed. We assigned 12 trained SPs to PPs practicing in 30 CHC catchment areas in Bandung city, Indonesia. For comparison, two scenarios were also presented to the CHCs. A total of 341 successful SP visits were made to 225 private general practitioners (GPs), 29 private specialists, and 30 CHCs. When laboratory results were not available, adherence to the recommended course of action, i.e., sputum examination, was low among private GPs (31%) and private specialists (20%), while it was requested in 87% of visits to the CHCs. PPs preferred chest X-ray (CXR) in all scenarios, with requests made in 66% of visits to private GPs and 84% of visits to private specialists (vs. 8% CHCs). Prescriptions of incorrect TB drug regimens were reported from 7% and 13% of visits to private GPs and specialists, respectively, versus none of the CHCs. Indonesian PPs have a clear preference for CXR over microbiological testing for triaging presumptive TB patients, and inappropriate prescription of TB drugs is not uncommon. These findings warrant actions to increase awareness among PPs about the importance of microbiological testing and of administering appropriate TB drug regimens. SP studies can be used to assess the impact of these interventions on providers' adherence to guidelines.

Tuberculin skin test and Interferon-gamma release assay agreement, and associated factors with latent tuberculosis infection, in medical and nursing students in Bandung, Indonesia.

BACKGROUND: No gold standard diagnostic test exists for latent tuberculosis infection (LTBI). The intra-dermal tuberculin skin test (TST) has known limitations and Interferon-gamma release assays (IGRA) have been developed as an alternative. We aimed to assess agreement between IGRA and TST, and risk factors for test positivity, in Indonesian healthcare students. METHODS: Medical and nursing students starting their clinical training were screened using IGRA and TST. Agreement between the two tests was measured using Cohen's Kappa coefficient. Logistic regression was used to identify factors associated with test positivity. RESULTS: Of 266 students, 43 (16.2%) were IGRA positive and 85 (31.9%) TST positive. Agreement between the two tests was 74.7% (kappa 0.33, 95% CI 0.21-0.45, P<0.0001). Students who had direct contact with family or friends with TB were less likely to be test positive using IGRA (AOR 0.18, 95% CI 0.05-0.64) and using TST (AOR 0.51, 95% CI 0.26-0.99). CONCLUSION: Test positivity for LTBI was lower when measured by IGRA than by TST, with poor agreement between the two tests. Known close TB contact was unexpectedly negatively associated with positivity by either test. Longitudinal studies may be required to help determine the best test for LTBI in healthcare students in Indonesia.

Late presentation of HIV infection among adults in New Zealand from 2011 to 2020.

OBJECTIVES: Early diagnosis of HIV is essential for successful treatment and controlling HIV spread in a population. We examined the frequency and characteristics of adults diagnosed late with HIV in New Zealand from 2011-2020. METHODS: Routine surveillance data were analysed. Those previously diagnosed overseas or as part of immigration screening, or with missing CD4 count were excluded. 'Late presentation' was defined as a CD4 count <350 cells/µL or an AIDS-defining event. 'Advanced HIV disease' were those with a CD4 count <200 cells/µL or an AIDS-defining event. Relative risks were calculated using Poisson regression. RESULTS: Of 1145 people, 40.5% presented late; 24.9% had advanced HIV disease. Of the 464 late diagnoses, 65.5% occurred among men-who-have-sex-with-men (MSM), 26.1% among heterosexuals, 8.4% among others. Heterosexual men and women were more likely to present late (55.3%) compared to MSM (35.6%). Amongst MSM, those who were older, of an ethnicity other than European, acquired HIV overseas, tested because symptomatic, or had their last negative test >2 years prior were more likely to present late and have advanced disease. Amongst heterosexuals, older age, tested because symptomatic, and Pacific ethnicity were associated with late presentation, and Maori, Pacific and Asian people were more likely to have advanced disease. CONCLUSIONS: There continues to be a high proportion of people diagnosed late with HIV. Identifying barriers for testing, missed opportunities for screenings and other factors that delay HIV diagnosis could help develop effective strategies to reduce this burden of late presentation - particularly among heterosexual individuals, non-Europeans, and older people.

Smoking Among High School Students in Dili, Timor-Leste: Prevalence, Potential Determinants and Opportunities for Prevention and Control.

Smoking initiation is concentrated among young people which strongly influences future smoking prevalence. This study aimed to investigate the prevalence of smoking and other tobacco product use and potential determinants in a cross-sectional survey of 1 121 students aged 13 to 15 years in Dili, Timor-Leste. The prevalence of ever using a tobacco product was 40.4% (males 55.5%; females 23.8%) and of current use was 32.2% (males 45.3%; females 17.9%). In a logistic multivariable regression, factors associated with current use of any tobacco product were being male, ≥US$1 weekly pocket money, parents smoking, exposure at home, and exposure in other locations. The findings suggest that reducing the very high use of tobacco among adolescents in Timor-Leste will require new policy measures, enhanced enforcement of current legislation as well as a focused commitment to targeted smoke-free education campaigns, and community-based health promotion to support parents to quit smoking and not smoke around children.

Feasibility study of the prevalence of latent tuberculosis infection for Maori in the Waikato region, Aotearoa New Zealand.

OBJECTIVE: This study aimed to assess the feasibility of conducting a representative tuberculin skin test (TST) survey for Maori in Aotearoa New Zealand and to estimate the prevalence of latent tuberculosis (TB) infection. METHODS: Participants were Maori in the Waikato region, recruited by a Maori nurse, through: 1) random household selection from the Electoral Roll; 2) randomly selected prison inmates; and 3) community and health settings. A TB history and symptoms questionnaire was completed, TST performed and investigation of those with TST induration ≥10mm. RESULTS: Random household selection was resource intensive and only contributed 14 participants. Repeated random selection of prison lists were required to recruit 207 participants and there were no positive TST cases. Community and health settings yielded the highest participation (n=370) and the three people (0.5%) with TST ≥10mm. Age ≥45 years and history of contact with a TB case were associated with TST induration ≥5mm (n=39; 6.6%). CONCLUSIONS: The community and health settings were the only feasible options for recruitment. The overall prevalence of a positive TST in the study population was low. A 5mm cut-off may be best to maximise sensitivity for future studies. IMPLICATIONS FOR PUBLIC HEALTH: A mixture of sample selection processes that are more targeted are needed to identify Maori with latent TB infection.

HIV in women in Aotearoa New Zealand: 25 years of surveillance data.

AIM: We describe the characteristics of women diagnosed with HIV and AIDS in Aotearoa New Zealand over the last 25 years, and of women living with HIV in New Zealand in order to guide the response for HIV prevention and care. METHODS: Data on women diagnosed with HIV and AIDS in New Zealand (1996-2020) were collected through routine surveillance case reports from healthcare providers. CD4 cell count <350 cells/mm³ was considered a late diagnosis. Women living with HIV by 31 December 2020 included those first diagnosed in New Zealand and those previously diagnosed overseas. RESULTS: A total of 634 women have been diagnosed with HIV (18% of all diagnoses in this time): most cases were acquired through heterosexual contact (82%). Twenty-eight percent (n=180/634) acquired HIV in New Zealand, of whom 43% were diagnosed late. AIDS was diagnosed in 128 women (72% within three months of HIV diagnosis). An estimated 570 women (77% aged >40 years) were living with diagnosed HIV at the end of 2020. CONCLUSION: The number of women diagnosed with HIV each year in New Zealand has remained steady over recent years. More timely testing and diagnosis is essential to ensure women with HIV have access to appropriate treatment and support.

Tuberculosis infection control measures and knowledge in primary health centres in Bandung, Indonesia.

Background: Health care workers (HCWs) in low- and middle-income countries (LMICs) continue to have an unacceptably high prevalence and incidence of Mycobacterium tuberculosis infection due to high exposure to tuberculosis (TB) cases at health care facilities and often inadequate infection control measures. This can contribute to an increased risk of transmission not only to HCWs themselves but also to patients and the general population. Aim: We assessed implementation of TB infection control measures in primary health centres (PHCs) in Bandung, Indonesia, and TB knowledge among HCWs. Methods: A cross-sectional study was conducted between May and November 2017 amongst a stratified sample of the PHCs, and their HCWs, that manage TB patients in Bandung. Questionnaires were used to assess TB infection control measures plus HCW knowledge. Summary statistics, linear regression and the Kruskal-Wallis test were used for analysis. Results: The median number of TB infection control measures implemented in 24 PHCs was 21 of 41 assessed. Only one of five management controls was implemented, 15 of 24 administrative controls, three of nine environmental controls and one of three personal respiratory protection controls. PHCs with TB laboratory facilities and high TB case numbers were more likely to implement TB infection control measures than other PHCs (p=0.003). In 398 HCWs, the median number of correct responses for knowledge was 10 (IQR 9-11) out of 11. Discussion: HCWs had good TB knowledge. TB infection control measures were generally not implemented and need to be strengthened in PHCs to reduce M. tuberculosis transmission to HCWs, patients and visitors.

Mycobacterium tuberculosis infection and disease in healthcare workers in a tertiary referral hospital in Bandung, Indonesia.

Background: Healthcare workers (HCWs), especially in high tuberculosis (TB) incidence countries, are at risk of Mycobacterium tuberculosis infection and TB disease, likely due to greater exposure to TB cases and variable implementation of infection control measures. Aim: We aimed to estimate the prevalence of tuberculin skin test (TST) positivity, history of TB and to identify associated risk factors in HCWs employed at a tertiary referral hospital in Bandung, Indonesia. Methods: A cross-sectional study was conducted from April to August 2018. A stratified sample of the HCWs were recruited, screened by TST, assessed for TB symptoms, history of TB disease and possible risk factors. Prevalence of positive TST included diagnosis with TB after starting work. HCWs with TB disease diagnosed earlier were excluded. Survey weights were used for all analyses. Possible risk factors were examined using logistic regression; adjusted odds ratios and 95% confidence intervals (CI) are presented. Results: Of 455 HCWs recruited, 42 reported a history of TB disease (25 after starting work) and 395 had a TST result. The prevalence of positive TST was 76.9% (95% CI 72.6-80.8%). The odds increased by 7% per year at work (95% CI 3-11%) on average, with a rapid rise in TST positivity up to 10 years of work and then a plateau with around 80% positive. Discussion: A high proportion of HCWs had a history of TB or were TST positive, increasing with longer duration of work. A package of TB infection control measures is needed to protect HCWs from Mycobacterium tuberculosis infection.

High risk of Mycobacterium tuberculosis infection among medical and nursing students in Indonesia: a 1-year prospective study.

BACKGROUND: Medical and nursing students entering their clinical programmes are at increased risk for tuberculosis (TB) in TB-endemic settings. Relatively little is known about Mycobacterium tuberculosis infection among such students in high-endemic countries. METHODS: We examined M. tuberculosis infection among medical and nursing students starting clinical training in Bandung, Indonesia using interferon-γ release assay (IGRA) QuantiFERON-TB Gold Plus. IGRA-negative students had a repeat test after 1 y and logistic regression was used to identify factors associated with IGRA positivity or conversion. RESULTS: There were 379 students included in this study: 248 (65.4%) were medical students and 131 (34.6%) were nursing students. Of 379 students, 70 (18.5%) were IGRA positive at baseline. Of 293 IGRA-negative students with 1-y results, 26 (8.9%) underwent IGRA conversion. Being a medical student (adjusted relative risk [ARR] 5.15 [95% confidence interval {CI} 1.82 to 14.59], p=0.002) and participation in sputum collection or bronchoscopy were associated with IGRA conversion (ARR 2.74 [95% CI 1.29 to 5.79], p=0.008). CONCLUSIONS: Medical and nursing students entering clinical training are at high risk of M. tuberculosis infection and need improved infection prevention and control strategies.

A public health intervention package for increasing tuberculosis notifications from private practitioners in Bandung, Indonesia (INSTEP2): A cluster-randomised controlled trial protocol.

Background. A significant proportion of tuberculosis (TB) patients globally make their initial visit for medical care to either an informal provider or a private practitioner, and many are not formally notified. Involvement of private practitioners (PPs) in a public-private mix for TB (TB-PPM) provides an opportunity for improving TB control. However, context-specific interventions beyond public-private agreements and mandatory notification are needed. In this study we will evaluate whether a tailored intervention package can increase TB notifications from PPs in Indonesia. Methods. This is a cluster-randomized trial of a multi-component public health intervention. 36 community health centre (CHC) areas will be selected as study locations and randomly allocated to intervention and control arms (1:1). PPs in the intervention areas will be identified using a mapping exercise and recruited into the study if they are eligible and consent. They will receive a tailored intervention package including in-person education about TB management along with bimonthly electronic refreshers, context-specific selection of referral pathways, and access to a TB-reporting app developed in collaboration with the National TB programme. The primary hypothesis is that the intervention package will increase the TB notification rate. The primary outcome will be measured by collecting notification data from the CHCs in intervention and control arms at the end of a 1-year observation period and comparing with the 1-year pre-intervention. The primary analysis will be intention-to-treat at the cluster level, using a generalised mixed model with repeated measures of TB notifications for 1 year pre- and 1 year post-intervention. Discussion. The results from this study will provide evidence on whether a tailored intervention package is effective in increasing the number of TB notifications, and whether the PPs refer presumptive TB cases correctly. The study results will guide policy in the development of TB-PPM in Indonesia and similar settings.
