Abstract
BACKGROUND Although screening of household contacts (HHCs) of TB patients and provision of TB preventive therapy (TPT) is a key intervention to end the TB epidemic, their implementation globally is dismal. We assessed whether introducing a '7-1-7' timeliness metric was workable for implementing HHC screening among index patients with pulmonary TB diagnosed by private providers in Chennai, India, between November 2022 and March 2023.METHODS This was an explanatory mixed-methods study (quantitative-cohort and qualitative-descriptive).RESULTS There were 263 index patients with 556 HHCs. In 90% of index patients, HHCs were line-listed within 7 days of anti-TB treatment initiation. Screening outcomes were ascertained in 48% of HHCs within 1 day of line-listing. Start of anti-TB treatment, TPT or a decision to receive neither was achieved in 57% of HHC within 7 days of screening. Overall, 24% of screened HHCs in the '7-1-7' period started TPT compared with 16% in a historical control (P < 0.01). Barriers to achieving '7-1-7' included HHC reluctance for evaluation or TPT, refusal of private providers to prescribe TPT and reliance on facility-based screening of HHCs instead of home visits by health workers for screening.CONCLUSIONS Introduction of a timeliness metric is a workable intervention that adds structure to HHC screening and timely management..

Feasibility, enablers and challenges of using timeliness metrics for household contact tracing and TB preventive therapy in Pakistan. PLoS One 2023; 18:e0295580. [PMID: 38079438 PMCID: PMC10712885 DOI: 10.1371/journal.pone.0295580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 11/23/2023] [Indexed: 12/18/2023] Open
Abstract
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.

Managing Comorbidities, Determinants and Disability at Start and End of TB Treatment under Routine Program Conditions in China. Trop Med Infect Dis 2023; 8:341. [PMID: 37505637 PMCID: PMC10383887 DOI: 10.3390/tropicalmed8070341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/29/2023] Open
Abstract
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.

Contact Tracing and Tuberculosis Preventive Therapy for Household Child Contacts of Pulmonary Tuberculosis Patients in the Kyrgyz Republic: How Well Are We Doing? Trop Med Infect Dis 2023; 8:332. [PMID: 37505628 PMCID: PMC10386269 DOI: 10.3390/tropicalmed8070332] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 06/08/2023] [Accepted: 06/19/2023] [Indexed: 07/29/2023] Open
Abstract
Early identification, screening and investigation for tuberculosis (TB), and provision of TB preventive therapy (TPT), reduces risk of TB among child household contacts of pulmonary TB patients (index patients). A cohort study was conducted to describe the care cascade and timeliness of contact tracing and TPT initiation among child household contacts (aged < 15 years) of index patients initiated on TB treatment in Bishkek, the Kyrgyz Republic during October 2021-September 2022. In the register, information on the number of child household contacts was available for 153 (18%) of 873 index patients. Of 297 child household contacts identified, data were available for 285, of whom 261 (92%) were screened for TB. More than 50% were screened after 1 month of the index patient initiating TB treatment. TB was diagnosed in 23/285 (9%, 95% CI: 6-13%) children. Of 238 TB-free children, 130 (55%) were eligible for TPT. Of the latter, 64 (49%) were initiated on TPT, of whom 52 (81%) completed TPT. While TPT completion was excellent, there was deficiency in contact identification, timely screening and TPT initiation. Thus, healthcare providers should diligently request and record details of child household contacts, adhere to contact tracing timelines and counsel caregivers regarding TPT.

Antibiotic resistance and consumption before and during the COVID-19 pandemic in Valle del Cauca, Colombia. Rev Panam Salud Publica 2023; 47:e10. [PMID: 37082532 PMCID: PMC10105594 DOI: 10.26633/rpsp.2023.10] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Accepted: 10/26/2022] [Indexed: 04/22/2023] Open
Abstract
Objective To assess changes in antibiotic resistance of eight of the World Health Organization priority bug-drug combinations and consumption of six antibiotics (ceftriaxone, cefepime, piperacillin/tazobactam, meropenem, ciprofloxacin, vancomycin) before (March 2018 to July 2019) and during (March 2020 to July 2021) the COVID-19 pandemic in 31 hospitals in Valle del Cauca, Colombia. Methods This was a before/after study using routinely collected data. For antibiotic consumption, daily defined doses (DDD) per 100 bed-days were compared. Results There were 23 405 priority bacterial isolates with data on antibiotic resistance. The total number of isolates increased from 9 774 to 13 631 in the periods before and during the pandemic, respectively. While resistance significantly decreased for four selected bug-drug combinations (Klebsiella pneumoniae, extended spectrum beta lactamase [ESBL]-producing, 32% to 24%; K. pneumoniae, carbapenem-resistant, 4% to 2%; Pseudomonas aeruginosa, carbapenem-resistant, 12% to 8%; Acinetobacter baumannii, carbapenem-resistant, 23% to 9%), the level of resistance for Enterococcus faecium to vancomycin significantly increased (42% to 57%). There was no change in resistance for the remaining three combinations (Staphylococcus aureus, methicillin-resistant; Escherichia coli, ESBL-producing; E. coli, carbapenem-resistant). Consumption of all antibiotics increased. However, meropenem consumption decreased in intensive care unit settings (8.2 to 7.1 DDD per 100 bed-days). Conclusions While the consumption of antibiotics increased, a decrease in antibiotic resistance of four bug-drug combinations was observed during the pandemic. This was possibly due to an increase in community-acquired infections. Increasing resistance of E. faecium to vancomycin must be monitored. The findings of this study are essential to inform stewardship programs in hospital settings of Colombia and similar contexts elsewhere.

Quality, Equity and Partnerships in Mixed Methods and Qualitative Research during Seven Years of Implementing the Structured Operational Research and Training Initiative in 18 Countries. Trop Med Infect Dis 2022; 7:tropicalmed7100305. [PMID: 36288046 PMCID: PMC9610844 DOI: 10.3390/tropicalmed7100305] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/03/2022] [Accepted: 10/12/2022] [Indexed: 11/16/2022] Open
Abstract
Introduction: Qualitative studies are often inadequately reported, making it difficult to judge their appropriateness for decision making in public health. We assessed the publication characteristics and quality of reporting of qualitative and mixed-method studies from the Structured Operational Research and Training Initiative (SORT IT), a global partnership for operational research capacity building. Methods: A cross-sectional analysis of publications to assess the qualitative component using an adapted version of the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Results: In 67 publications involving 18 countries, 32 journals and 13 public health themes, 55 were mixed-methods studies and 12 were qualitative studies. First authorship from low-and-middle-income (LMIC) countries was present in 64 (96%), LMIC last authorship in 55 (82%), and female first authorship in 30 (45%). The mean LMIC institutions represented per publication was five (range 1–11). Sixty-three (94%) publications were open access. Reporting quality was graded as ‘good’ to ‘excellent’ in 60 (89%) publications, ‘fair’ in five (8%) and ‘poor’ in two (3%). Conclusion: Most SORT IT publications adhered to COREQ standards, while supporting gender equity in authorship and the promotion of LMIC research leadership. SORT IT plays an important role in ensuring quality of evidence for decision making to improve public health.

High Levels of Outpatient Antibiotic Prescription at a District Hospital in Ghana: Results of a Cross Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:10286. [PMID: 36011917 PMCID: PMC9407799 DOI: 10.3390/ijerph191610286] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/13/2022] [Accepted: 08/16/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Monitoring of antibiotic prescription practices in hospitals is essential to assess and facilitate appropriate use. This is relevant to halt the progression of antimicrobial resistance. METHODS Assessment of antibiotic prescribing patterns and completeness of antibiotic prescriptions among out-patients in 2021 was conducted at the University Hospital of Kwame Nkrumah University of Science and Technology in the Ashanti region of Ghana. We reviewed electronic medical records (EMR) of 49,660 patients who had 110,280 encounters in the year. RESULTS The patient encounters yielded 350,149 prescriptions. Every month, 33-36% of patient encounters resulted in antibiotic prescription, higher than the World Health Organization's (WHO) recommended optimum of 27%. Almost half of the antibiotics prescribed belonged to WHO's Watch group. Amoxicillin-clavulanic acid (50%), azithromycin (29%), ciprofloxacin (28%), metronidazole (21%), and cefuroxime (20%) were the most prescribed antibiotics. Antibiotic prescribing parameters (indication, name of drug, duration, dose, route, and frequency) were documented in almost all prescriptions. CONCLUSIONS Extending antimicrobial stewardship to the out-patient settings by developing standard treatment guidelines, an out-patient specific drug formulary, and antibiograms can promote rational antibiotic use at the hospital. The EMR system of the hospital is a valuable tool for monitoring prescriptions that can be leveraged for future audits.

Compliance with Medication amongst Persons with Diabetes Mellitus during the COVID-19 Pandemic, Kerala, India: A Cross Sectional Study. Trop Med Infect Dis 2022; 7:tropicalmed7060104. [PMID: 35736982 PMCID: PMC9228986 DOI: 10.3390/tropicalmed7060104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/02/2022] [Accepted: 06/08/2022] [Indexed: 02/01/2023] Open
Abstract
Compliance with medication in persons with diabetes mellitus (DM) has been a challenge during the COVID-19 pandemic, leading to poor glycemic control and higher risk of complications. In the state of Kerala, India, 20−25% of adults have DM. Our cross-sectional study aimed to assess medication compliance and factors associated with poor compliance in DM persons attending selected primary care government facilities in Kerala during the COVID-19 pandemic. Persons registered with DM for >6 months were consecutively interviewed between August and September 2021. Poor compliance was defined as answering “No” to one or more of three questions related to access and intake of medication two weeks prior to and the day before the interview. Factors independently associated with poor compliance were assessed using adjusted prevalence ratios (aPr) and 95% confidence intervals. Of the 560 DM persons included, 209 (37%) exhibited poor compliance. Factors associated with poor compliance were age 19−45 years (aPr 1.4, 1.1−1.9); inability to be blood glucose tested during the COVID-19 pandemic (aPr 3.6, 2.9−4.3); not having COVID-19 (aPr 1.4, 1.0−1.9); and being double vaccinated against COVID-19 (aPr 1.4, 1.1−2.0). Focused attention must be paid to these groups to improve medication compliance and prevent DM complications and severe COVID-19-related disease.

Abstract
Kerala, a southern state in India, experienced a slightly different COVID-19 pandemic than the rest of India. Using data from daily COVID-19 bulletins and two other Kerala health information systems, this study reported on epidemiological characteristics and response measures of the COVID-19 pandemic between January 2020 and December 2021. After the first six months, Kerala experienced three distinct phases, with COVID-19 cases peaking in October 2020, May 2021, and August 2021. This contrasts with India, which experienced two main peaks in September 2020 and May 2021. The demographic profile of cases aligned with the national profile except for a slight increase of COVID-19 in persons aged ≥60 years. Monthly COVID-19 deaths increased dramatically from May 2021 onwards in line with case numbers but also reflecting changes in definitions of COVID-19 deaths. Case fatality for the two years was significantly higher in males than females, increased with increasing age groups, and varied between districts (p < 0.001). Trends in bed occupancy in field hospitals, hospitals for severe disease, intensive care units, and mechanical ventilation mirrored the different phases of the pandemic. The monitoring system in Kerala allowed certain aspects of the pandemic to be mapped, but it would benefit from further strengthening.

Abstract
WHO recommends surveillance for COVID-19 among travelers at Points of Entry (POE) to countries. At 13 selected POE at the Nepal-India border, between March 2021 and July 2021, we describe the screening, testing, diagnosis and isolation practices of COVID-19 amongst travelers. Those who stayed in India or elsewhere for > one day and those who did not have a negative RT-PCR result within the last 72 h of travel were tested for COVID-19 with rapid antigen diagnostic tests. Daily surveillance reports maintained at POE were used for analysis. Of 337,338 travelers screened, 69,886 (21%) were tested and 3907 (6%) were diagnosed with COVID-19. The proportions tested averaged 15% during April-May when screened numbers were high and increased to 35% in July when screened numbers had decreased. The proportions diagnosed positive peaked at 10% in April-May, but decreased to below 1% in June and July. Testing coverage varied from 0−99% in the different POE. Most COVID-19 cases were Nepalese, male, <60 years of age, migrant workers and presented with fever. Of COVID-19 cases, 32% had home-based isolation, 64% underwent community-based isolation and the remainder either went to hospital or returned to India. In conclusion, about one fifth of travelers overall were tested, with coverage varying considerably over time and among different POE. Strengthening surveillance processes at POE is needed.

Abstract
Inappropriate use of antibiotics during the COVID-19 pandemic has the potential to increase the burden of antimicrobial resistance. In this study, we report on the prevalence of antibiotic use and its associated factors among suspected and confirmed COVID-19 patients admitted to 35 health facilities in Sierra Leone from March 2020-March 2021. This was a cross-sectional study using routinely collected patient data. Of 700 confirmed COVID-19 patients, 47% received antibiotics. The majority (73%) of the antibiotics belonged to the 'WATCH' group of antibiotics, which are highly toxic and prone to resistance. The most frequently prescribed antibiotics were azithromycin, ceftriaxone, amoxicillin, metronidazole, and amoxicillin-clavulanic acid. Antibiotic use was significantly higher in patients aged 25-34 years than in those with severe disease. Of 755 suspected COVID-19 patients, 61% received antibiotics, of which the majority (58%) belonged to the 'WATCH' category. The most frequently prescribed antibiotics were ceftriaxone, metronidazole, azithromycin, ciprofloxacin, and amoxycillin. The prevalence of antibiotic use among suspected and confirmed COVID-19 patients admitted to healthcare facilities in Sierra Leone was high and not in line with national and WHO case management guidelines. Training of health care providers, strengthening of antimicrobial stewardship programs, and microbiological laboratory capacity are urgently needed.

Abstract
SETTING Patan Hospital, a tertiary care hospital in Lalitpur District, Nepal. OBJECTIVES To describe the annual parenteral antibiotic consumption in 1) defined daily dose (DDD) and DDD per 100 admissions; 2) calculate DDD per 100 admissions and proportions by pharmacological subgroup, chemical subgroup and AWaRe categories; and 3) describe patient expenditure on parenteral antibiotics as a proportion of the total patient expenditure on drugs and consumables between 2017 and 2019. DESIGN This was a cross-sectional study. RESULTS Total DDD of parenteral antibiotics increased by 23% from 39,639.7 in 2017 to 48,947.7 in 2019. DDD per 100 admissions increased by 10% from 172.1 in 2017 to 190.2 in 2019. Other beta-lactam antibacterials comprised the most frequently consumed pharmacological subgroup. The chemical substance most often consumed was ceftriaxone, with an increasing trend in the consumption of vancomycin and meropenem. Parenteral antibiotics in 'Watch' category were the most consumed over the study period, with a decreasing trend in 'Access' and increasing trend in 'Reserve' categories. CONCLUSION We aimed to understand the consumption of parenteral antibiotics at a tertiary care hospital and found that Watch antibiotics comprised the bulk of antibiotic consumption. Overconsumption of antibiotics from the 'Watch' and 'Reserve' categories can promote antimicrobial resistance; recommendations were therefore made for their rational use.

Abstract
SETTING A referral hospital in Kavre, Nepal. OBJECTIVES To assess 1) compliance with National Antibiotic Treatment Guidelines (NATG), specifically, whether the administration of surgical antibiotic prophylaxis (SAP) (initial dosing and redosing) was in compliance with NATG for patients who were and were not eligible, and 2) development of surgical site infections (SSIs) among patients who underwent surgery in the Department of General Surgery (July-December 2019). DESIGN This was a retrospective cohort analysis. RESULTS The analysis included 846 patients, of which 717 (85%) patients were eligible for SAP and 129 (15%) were ineligible. Of those eligible, 708 (99%) received the initial dose; while 65 (50%) of the ineligible did not receive any dose. Of those who received the initial dose, 164 (23%) were eligible for redosing. Of these, only 23 (14%) received at least one redosing and 141 (86%) did not receive it. Overall compliance with NATG was achieved in 75% (632/846) of patients. SSIs occurred in 23 (3%) patients, 8 (35%) of whom did not have SAP administered according to NATG. CONCLUSION A relatively high overall compliance with NATG for SAP administration was reported. Recommendations were made to improve compliance among those who were ineligible for SAP and those who were eligible for redosing.

Abstract
The Structured Operational Research and Training Initiative (SORT IT) model has contributed to building research capacity and has produced evidence for improving public health program performance in countries with limited research capacity. The model involves hands-on mentorship and consists of three modules/weeks. It is recognized to be an innovative research capacity building model. In a world changed by COVID-19, where bringing people together is not viable, an innovative, interactive, web-based, knowledge-transfer platform (e-SORT IT) for virtual implementation of SORT IT modules was created. The platform design imitated the residential course as closely as possible with the same lectures, plenary sessions, and breakout rooms. Despite the challenges, the platform performed well and even though participants and mentors were located in eight different time zones, the course was successful; 90% of participants achieved their milestones and 10 manuscripts were successfully completed. Participant evaluation revealed a satisfaction level that was nearly equivalent to the residential module. However, mentor evaluation indicated a number of shortcomings including capacity building, professional networking, communication, engagement, and contribution by participants, as well as overall module success. In conclusion, COVID-19 stimulated the creation of the e-SORT IT platform that provided a functional alternative to the residential version. Despite the limitations of reduced capacity building and networking, the e-SORT IT platform should be considered a success - it delivered the goods. This is an example of innovation and flexibility, two attributes that are sorely needed to maintain activities during the pandemic and beyond.

[PMID: 34609958 PMCID: PMC9323534 DOI: 10.3855/jidc.13783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 07/12/2021] [Indexed: 11/01/2022] Open
Abstract
INTRODUCTION Adherence to second-line antituberculosis drug is challenging. A combination of strategies needs to be implemented to achieve adherence. In Georgia an optimized adherence support (OAS) - a package of education, psychosocial support and adherence counselling - was added to the already existing package of adherence support (supervised treatment, adherence incentives, transport cost reimbursement) to improve adherence and increase treatment success. We assessed the additive benefits of OAS on adherence and treatment outcomes. METHODOLOGY This was a before and after cohort study using routine programme data in the National Center for Tuberculosis and Lung Diseases in Tbilisi. All adult rifampicin- and multidrug-resistant tuberculosis (RR/MDR-TB) patients enrolled for treatment under directly observed therapy in the NCTLD during the period before (June 2015 - January 2016) and after (June 2017 - January 2018) were included in the study. Primary outcomes were: i) adequate adherence defined as ≥ 85% of days covered by TB medication during the whole treatment period; ii) final treatment outcomes. RESULTS Of 221 RR/MDR-TB, most patients were male (76%, N = 167) with a mean age of 41 ± 14 years. Adherence data was available for 111 patients in the 'before' and 97 patients in the 'after' cohort. Adequate adherence was achieved by 62% (69/111) in the 'before' and 70% (68/97) in the 'after' cohort (p = 0.290). Overall treatment success was 64% (73/114) and 63% (67/107) in the 'before' and 'after' cohorts respectively (p = 0.937). CONCLUSIONS Implementation of OAS had modest effect on adherence and had no additive benefits on treatment outcomes among RR/MDR-TB patients on 18-20 months regimen.

Bacteria and Their Antibiotic Resistance Profiles in Ambient Air in Accra, Ghana, February 2020: A Cross-Sectional Study. Trop Med Infect Dis 2021; 6:tropicalmed6030110. [PMID: 34201909 PMCID: PMC8293412 DOI: 10.3390/tropicalmed6030110] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 06/03/2021] [Accepted: 06/09/2021] [Indexed: 11/22/2022] Open
Abstract
Inappropriate use of antibiotics has led to the presence of antibiotic-resistant bacteria in ambient air. There is no published information about the presence and resistance profiles of bacteria in ambient air in Ghana. We evaluated the presence and antibiotic resistance profiles of selected bacterial, environmental and meteorological characteristics and airborne bacterial counts in 12 active air quality monitoring sites (seven roadside, two industrial and three residential) in Accra in February 2020. Roadside sites had the highest median temperature, relative humidity, wind speed and PM10 concentrations, and median airborne bacterial counts in roadside sites (115,000 CFU/m3) were higher compared with industrial (35,150 CFU/m3) and residential sites (1210 CFU/m3). Bacillus species were isolated in all samples and none were antibiotic resistant. There were, however, Pseudomonas aeruginosa, Escherichia coli, Pseudomonas species, non-hemolytic Streptococci, Coliforms and Staphylococci species, of which six (50%) showed mono-resistance or multidrug resistance to four antibiotics (penicillin, ampicillin, ciprofloxacin and ceftriaxone). There was a positive correlation between PM10 concentrations and airborne bacterial counts (rs = 0.72), but no correlations were found between PM10 concentrations and the pathogenic bacteria nor their antibiotic resistance. We call for the expansion of surveillance of ambient air to other cities of Ghana to obtain nationally representative information.

TB and COVID-19: paying attention to diabetes mellitus. Trans R Soc Trop Med Hyg 2021; 115:600-602. [PMID: 32986096 PMCID: PMC7989166 DOI: 10.1093/trstmh/trab035] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 01/22/2021] [Accepted: 02/13/2021] [Indexed: 01/21/2023] Open
Abstract
In 2019, global diabetes prevalence was 463 million. Diabetes increases the risk of TB and adverse treatment outcomes including death and relapse. Diabetes also increases the risk of severe disease, multi-organ failure, coagulopathy and death in COVID-19. TB and COVID-19 share many features, suggesting opportunities to integrate prevention, diagnosis and care. Three areas for further work are highlighted: better infection control in diabetes clinics, easier and quicker diagnosis using similar technology platforms and optimal blood glucose control. The funding and resources for COVID-19 should be harnessed to improve TB and diabetes care and achieve their respective sustainable development goal targets.

National Antibiotic Consumption for Human Use in Sierra Leone (2017-2019): A Cross-Sectional Study. Trop Med Infect Dis 2021; 6:tropicalmed6020077. [PMID: 34068109 PMCID: PMC8163174 DOI: 10.3390/tropicalmed6020077] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 04/30/2021] [Accepted: 05/04/2021] [Indexed: 12/20/2022] Open
Abstract
Monitoring antibiotic consumption is crucial to tackling antimicrobial resistance. However, currently there is no system in Sierra Leone for recording and reporting on antibiotic consumption. We therefore conducted a cross-sectional study to assess national antibiotic consumption expressed as defined daily dose (DDD) per 1000 inhabitants per day using all registered and imported antibiotics (categorized under the subgroup J01 under the anatomical and therapeutic classification (ATC) system) as a proxy. Between 2017–2019, total cumulative consumption of antibiotics was 19 DDD per 1000 inhabitants per day. The vast majority consisted of oral antibiotics (98.4%), while parenteral antibiotics made up 1.6%. According to therapeutic/pharmacological subgroups (ATC level 3), beta-lactam/penicillins, quinolones, and other antibacterials (mainly oral metronidazole) comprised 65% of total consumption. According to WHO Access, Watch, and Reserve (AWaRe), 65% of antibiotics consumed were Access, 31% were Watch, and no Reserve antibiotics were reported. The top ten oral antibiotics represented 97% of total oral antibiotics consumed, with metronidazole (35%) and ciprofloxacin (15%) together constituting half of the total. Of parenteral antibiotics consumed, procaine penicillin (32%) and ceftriaxone (19%) together comprised half of the total. Policy recommendations at global and national levels have been made to improve monitoring of antibiotic consumption and antibiotic stewardship.

Assessing the Real-Time Impact of COVID-19 on TB and HIV Services: The Experience and Response from Selected Health Facilities in Nairobi, Kenya. Trop Med Infect Dis 2021; 6:tropicalmed6020074. [PMID: 34068615 PMCID: PMC8163186 DOI: 10.3390/tropicalmed6020074] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 05/06/2021] [Accepted: 05/06/2021] [Indexed: 01/10/2023] Open
Abstract
There was concern that the COVID-19 pandemic would adversely affect TB and HIV programme services in Kenya. We set up real-time monthly surveillance of TB and HIV activities in 18 health facilities in Nairobi so that interventions could be implemented to counteract anticipated declining trends. Aggregate data were collected and reported monthly to programme heads during the COVID-19 period (March 2020–February 2021) using EpiCollect5 and compared with monthly data collected during the pre-COVID period (March 2019–February 2020). During the COVID-19 period, there was an overall decrease in people with presumptive pulmonary TB (31.2%), diagnosed and registered with TB (28.0%) and in those tested for HIV (50.5%). Interventions to improve TB case detection and HIV testing were implemented from August 2020 and were associated with improvements in all parameters during the second six months of the COVID-19 period. During the COVID-19 period, there were small increases in TB treatment success (65.0% to 67.0%) and referral of HIV-positive persons to antiretroviral therapy (91.2% to 92.9%): this was more apparent in the second six months after interventions were implemented. Programmatic interventions were associated with improved case detection and treatment outcomes during the COVID-19 period, suggesting that monthly real-time surveillance is useful during unprecedented events.

Characteristics, utilisation and influence of viewpoint articles from the Structured Operational Research and Training Initiative (SORT IT) - 2009-2020. F1000Res 2021; 10:198. [PMID: 34164113 PMCID: PMC8218027 DOI: 10.12688/f1000research.27349.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 11/19/2020] [Indexed: 11/20/2022] Open
Abstract
Background: The Structured Operational Research and Training Initiative (SORT IT) teaches the practical skills of conducting and publishing operational research (OR) to influence health policy and/or practice. In addition to original research articles, viewpoint articles are also produced and published as secondary outputs of SORT IT courses. We assessed the characteristics, use and influence of viewpoint articles derived from all SORT IT courses. Methods: This was a cross-sectional study involving all published viewpoint articles derived from the SORT IT courses held from August 2009 - March 2020. Characteristics of these papers were sourced from the papers themselves and from SORT-IT members involved in writing the papers. Data on use were sourced from the metrics provided on the online publishing platforms and from Google Scholar. Influence on policy and practice was self-assessed by the authors of the papers and was performed only for papers deemed to be 'calls for action'. Results: A total of 41 viewpoint papers were published. Of these, 15 (37%) were 'calls for action'. In total, 31 (76%) were published in open-access journals and the remaining 10 in delayed access journals. In 12 (29%) of the papers, first authors were from low and middle-income countries (LMICs). Female authors (54%) were included in 22, but only four (10%) and two (5%) of first and last authors respectively, were female. Only seven (17%) papers had available data regarding online views and downloads. The median citation score for the papers was four (IQR 1-9). Of the 15 'call for action' papers, six influenced OR capacity building, two influenced policy and practice, and three influenced both OR capacity building within SORT IT and policy and practice. Conclusion: Viewpoint articles generated during SORT IT courses appear to complement original OR studies and are valued contributors to the dissemination of OR practices in LMICs.

Investing in Operational Research Capacity Building for Front-Line Health Workers Strengthens Countries' Resilience to Tackling the COVID-19 Pandemic. Trop Med Infect Dis 2020; 5:tropicalmed5030118. [PMID: 32708821 PMCID: PMC7558759 DOI: 10.3390/tropicalmed5030118] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2020] [Revised: 07/14/2020] [Accepted: 07/15/2020] [Indexed: 11/16/2022] Open
Abstract
(1) Introduction. The Structured Operational Research and Training IniTiative (SORT IT) supports countries to build operational research capacity for improving public health. We assessed whether health workers trained through SORT IT were (1) contributing to the COVID-19 pandemic response and if so, (2) map where and how they were applying their SORT IT skills. (2) Methods. An online questionnaire survey of SORT IT alumni trained between 2009 and 2019. (3) Results. Of 895 SORT IT alumni from 93 countries, 652 (73%) responded to the survey and 417 were contributing to the COVID-19 response in 72 countries. Of those contributing, 307 (74%) were applying their SORT IT skills to tackle the pandemic in 60 countries and six continents including Africa, Asia, Europe, South Pacific and North/South America. Skills were applied to all the pillars of the emergency response with the highest proportions of alumni applying their skills in data generation/analysis/reporting (56%), situation analysis (55%) and surveillance (41%). Skills were also being used to mitigate the health system effects of COVID-19 on other diseases (27%) and in conducting research (26%). (4) Conclusion. Investing in people and in research training ahead of public health emergencies generates downstream dividends by strengthening health system resilience for tackling pandemics. It also strengthens human resources for health and the integration of research within health systems.

Strengthening the core health research capacity of national health systems helps build country resilience to epidemics: a cross-sectional survey. F1000Res 2020; 9:583. [PMID: 32595962 PMCID: PMC7308898 DOI: 10.12688/f1000research.24192.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/01/2020] [Indexed: 01/11/2024] Open
Abstract
Background: TDR, The Special Programme for Research and Training hosted at the World Health Organization, has long supported Low- and Middle-Income Countries in strengthening research capacity through three training programmes: the Postgraduate Training Scheme (PGTS), the Clinical Research and Development Fellowship (CRDF), and the Structured Operational Research Training InitiaTive (SORT IT). In the advent of the COVID-19 pandemic, we assessed whether those trained through these programmes were involved in the COVID-19 response and if so, in which area(s) of the emergency response they were applying their skills. Methods: From the records for each training programme, we identified the individuals who had completed training during the relevant timespan of each programme: 1999-2018 for the CRDF scheme, 2015-2020 for PGTS, and 2009-2019 for SORT-IT. Between March and April 2020, we sent trainees an online questionnaire by e-mail. Results: Out of 1254 trained, 1143 could be contacted and 699 responded to the survey. Of the latter, 411 were involved with the COVID-19 response, of whom 315 (77%) were applying their acquired skills in 85 countries. With some overlap between programmes, 84% of those trained through CRDF were applying their skills in 27 countries, 91% of those trained through PGTS were applying their skills in 19 countries, and through SORT IT, this was 73% in 62 countries. Skills were being applied in various areas of the emergency response, including: emergency preparedness, situation analysis/surveillance, infection control and clinical management, data generation, mitigating the effect of COVID on the health system, and research. Depending on the type of training programme, 26-74% were involved in implementation, operational or clinical research. Conclusion: Research training programmes build research capacity and equip health workers with transferable core competencies and skillsets prior to epidemics. This becomes invaluable in building health system resilience at a time of pandemics.

The Growing Importance of Tuberculosis Preventive Therapy and How Research and Innovation Can Enhance Its Implementation on the Ground. Trop Med Infect Dis 2020; 5:tropicalmed5020061.

Abstract
Ending the tuberculosis (TB) epidemic by 2030 requires two key actions: rapid diagnosis and effective treatment of active TB and identification and treatment of latent TB infection to prevent progression to active disease. We introduce this perspective by documenting the growing importance of TB preventive therapy on the international agenda coupled with global data showing poor implementation of preventive activities in programmatic settings. We follow this with two principal objectives. The first is to examine implementation challenges around diagnosis and treatment of active TB. Within this, we include recent evidence about the continued morbidity and heightened mortality that persists after TB treatment is successfully completed, thus elevating the importance of TB preventive therapy. The second objective is to outline how current TB preventive therapy activities have been shaped and are managed and propose how these can be improved through research and innovation. This includes expanding and giving higher priority to certain high-risk groups including those with fibrotic lung lesions on chest X-ray, showcasing the need to develop and deploy new biomarkers to more accurately predict risk of disease and making shorter treatment regimens, especially with rifapentine-isoniazid, more user-friendly and widely available. Ending the TB epidemic requires not only cure of the disease but preventing it before it even begins.

Building the capacity of public health programmes to become data rich, information rich and action rich. Public Health Action 2018; 8:34-36.

Abstract
Good quality, timely data are the cornerstone of health systems, but in many countries these data are not used for evidence-informed decision making and/or for improving public health. The SORT IT (Structured Operational Research and Training Initiative) model has, over 8 years, trained health workers in low- and middle-income countries to use data to answer important public health questions by taking research projects through to completion and publication in national or international journals. The D2P (data to policy) training initiative is relatively new, and it teaches health workers how to apply 'decision analysis' and develop policy briefs for policy makers: this includes description of a problem and the available evidence, quantitative comparisons of policy options that take into account predicted health and economic impacts, and political and feasibility assessments. Policies adopted from evidence-based information generated through the SORT IT and D2P approaches can be evaluated to assess their impact, and the cycle repeated to identify and resolve new public health problems. Ministries of Health could benefit from this twin-training approach to make themselves 'data rich, information rich and action rich', and thereby use routinely collected data in a synergistic manner to improve public health policy making and health care delivery.

Active case-finding for tuberculosis by mobile teams in Myanmar: yield and treatment outcomes. Infect Dis Poverty 2017; 6:77. [PMID: 28571575 PMCID: PMC5455111 DOI: 10.1186/s40249-017-0291-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2016] [Accepted: 03/21/2017] [Indexed: 11/16/2022] Open
Abstract
Background Since 2005, the Myanmar National Tuberculosis Programme (NTP) has been implementing active case finding (ACF) activities involving mobile teams in hard-to-reach areas. This study revealed the contribution of mobile team activities to total tuberculosis (TB) case detection, characteristics of TB patients detected by mobile teams and their treatment outcomes. Methods This was a descriptive study using routine programme data between October 2014 and December 2014. Mobile team activities were a one-stop service and included portable digital chest radiography (CXR) and microscopy of two sputum samples. The algorithm of the case detection included screening patients by symptoms, then by CXR followed by sputum microscopy for confirmation. Diagnosed patients were started on treatment and followed until a final outcome was ascertained. Results A total of 9 349 people with symptoms suggestive of TB were screened by CXR, with an uptake of 96.6%. Of those who were meant to undergo sputum smear microscopy, 51.4% had sputum examinations. Finally, 504 TB patients were identified by the mobile teams and the overall contribution to total TB case detection in the respective townships was 25.3%. Among total cases examined by microscopy, 6.4% were sputum smear positive TB. Treatment success rate was high as 91.8% in study townships compared to national rate 85% (2014 cohort). Conclusions This study confirmed the feasibility and acceptability of ACF by mobile teams in hard-to-reach contexts, especially when equipped with portable, digital CXR machines that provided immediate results. However, the follow-up process of sputum examination created a significant barrier to confirmation of the diagnosis. In order to optimize the ACF through mobile team activity, future ACF activities were needed to be strengthened one stop service including molecular diagnostics or provision of sputum cups to all presumptive TB cases prior to CXR and testing if CXR suggestive of TB.

Abstract
Background It is estimated that the standard, passive case finding (PCF) strategy for detecting cases of tuberculosis (TB) in Myanmar has not been successful: 26% of cases are missing. Therefore, alternative strategies, such as active case finding (ACF) by community volunteers, have been initiated since 2011. This study aimed to assess the contribution of a Community Based TB Care Programme (CBTC) by local non-government organizations (NGOs) to TB case finding in Myanmar over 4 years. Methods This was a descriptive study using routine, monitoring data. Original data from the NGOs were sent to a central registry within the National TB Programme and data for this study were extracted from that database. Data from all 84 project townships in five regions and three states in Myanmar were used. The project was launched in 2011. Results Over time, the number of presumptive TB cases that were referred decreased, except in the Yangon Region, although in some areas, the numbers fluctuated. At the same time, there was a trend for the proportion of cases treated, compared to those referred, that decreased over time (P = 0.051). Overall, among 84 townships, the contribution of CBTC to total case detection deceased from 6% to 4% over time (P < 0.001). Conclusions Contrary to expectations and evidence from previous studies in other countries, a concerning reduction in TB case finding by local NGO volunteer networks in several areas in Myanmar was recorded over 4 years. This suggests that measures to support the volunteer network and improve its performance are needed. They may include discussion with local NGOs human resources personnel, incentives for the volunteers, closer supervision of volunteers and improved monitoring and evaluation tools.

Monitoring delays in diagnosis of pulmonary tuberculosis in eight cities in Colombia. Rev Panam Salud Publica 2016; 39:12-18.

Abstract
Objective To measure time between onset of tuberculosis (TB) symptoms and start of treatment, and to identify factors associated with delay in eight Colombian cities. Methods Operational research with a retrospective analytical cohort design was conducted in 2014 using routinely collected data about new smear-positive pulmonary TB patients from eight cities in Colombia (Barranquilla, Bogotá, Bucaramanga, Cali, Cúcuta, Medellín, Pereira, and Villavicencio). Date of symptom onset was sourced from TB surveillance databases. Data on all other variables came from National TB Program (NTP) registers. Results There were 2 545 new cases of smear-positive pulmonary TB, but a plausible date of symptom onset was available for only 1 456 (57%). Median number of days between symptom onset and treatment start was 51 days (interquartile range: 27-101). A total of 72% of patients had a delay (> 30 days between symptom onset and treatment start), and 28% had a 3+ bacillary load at diagnosis. Based on multiple logistic regression, three factors were significantly associated with delay: being uninsured (odds ratio (OR): 1.30; 95% confidence interval (CI): 1.01-1.68) and having an unknown HIV status (OR: 1.81; CI: 1.04-3.17), which increased risk, and coming from a neighborhood with NTP-employed community health workers, which decreased risk (OR: 0.56; CI: 0.34-0.90). Conclusions Delays still prevent timely TB diagnosis and treatment in Colombia. As the country aims for TB elimination, delays must be reduced, especially in cities and vulnerable neighborhoods, to stop community transmission. The NTP should focus not only on the number of cases detected but also on how long it takes to detect them. To monitor interventions designed to reduce delays, additional dates in the process should be recorded routinely. In addition, reliability and completeness of data are crucial for monitoring.

HIV testing, antiretroviral therapy, and treatment outcomes in new cases of tuberculosis in Brazil, 2011. Rev Panam Salud Publica 2016; 39:26-31. [PMID: 27754538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2015] [Accepted: 11/09/2015] [Indexed: 06/06/2023] Open
Abstract
Objective To assess the implementation of HIV-related interventions for patients with tuberculosis (TB), as well as TB treatment outcomes in patients coinfected with HIV in Brazil in 2011. Methods This was a cross-sectional, operational research study of HIV-related interventions among TB cases and the sociodemographic and clinical characteristics of TB-HIV coinfected patients. It also used a retrospective cohort design to determine the association between antiretroviral therapy (ART) and favorable TB treatment outcomes. The source of data was a linkage of 2011 administrative health databases used by the National TB and HIV/AIDS Programs. Results Of 73 741 new cases of TB reported, 63.6% (46 865 patients) were tested for HIV; 10.3% were positive. Of patients with HIV, 45.9% or 3 502 were on ART. TB favorable outcome was achieved in 63.1% or 2 205 coinfected patients on ART and in only 35.4% or 1 459 of those not on ART. On multivariate analysis, the relative risk for the association between ART and TB treatment success was 1.72 (95% Confidence Interval = 1.64-1.81). Conclusions The linkage between national TB and HIV datasets has created a convenient baseline for ongoing monitoring of HIV testing, ART use, and TB treatment outcomes among coinfected patients. The low rates of HIV screening and ART use in 2011 need to be improved. The association between ART and treatment success adds to the evidence supporting timely initiation of ART for all patients with TB-HIV coinfection.

Culture and drug susceptibility testing among previously treated tuberculosis patients in the Dominican Republic, 2014. Rev Panam Salud Publica 2016; 39:60-64. [PMID: 27754535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2015] [Accepted: 10/19/2015] [Indexed: 06/06/2023] Open
Abstract
Multidrug-resistant tuberculosis (MDR-TB) is a major public health concern that threatens global progress toward effective TB control. The risk of MDR-TB is increased in patients who have received previous TB treatment. This article describes the performance of culture and drug susceptibility testing (DST) in patients registered as previously treated TB patients in the Dominican Republic in 2014, based on operational research that followed a retrospective cohort design and used routine program data. Under the current system of TB culturing and DST, the majority of patients with previously treated TB do not undergo DST, and those who do often experience considerable delay in obtaining their results. The lack of DST and delay in receiving DST results leads to underestimation of the number of MDR-TB cases and hinders the timely initiation of MDR-TB treatment.

Effect of increased ART-CPT uptake on tuberculosis outcomes and associated factors, Burundi, 2009-2013. Public Health Action 2015; 5:214-6. [PMID: 26767173 DOI: 10.5588/pha.15.0039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2015] [Accepted: 09/06/2015] [Indexed: 11/10/2022] Open
Abstract
We retrospectively examined 3579 records of human immunodeficiency virus infected tuberculosis (TB) patients diagnosed from January 2009 to June 2013 in 55 TB treatment facilities in Burundi, to demonstrate whether improvement of combined cotrimoxazole preventive therapy and antiretroviral therapy (ART) uptake was accompanied by improvement of treatment outcomes, and to describe associated factors. Treatment success rates increased from 71% to 80% (P < 0.001). While loss to follow-up and transfer-out rates declined significantly, death rates decreased modestly, and remained high, at 14%. ART uptake was worse in suburban areas and private for-profit institutions. World Health Organization targets could be achieved if peripheral health facilities were prioritised.

Time to ART Initiation among Patients Treated for Rifampicin-Resistant Tuberculosis in Khayelitsha, South Africa: Impact on Mortality and Treatment Success. PLoS One 2015; 10:e0142873. [PMID: 26555134 PMCID: PMC4640533 DOI: 10.1371/journal.pone.0142873] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2015] [Accepted: 10/27/2015] [Indexed: 11/18/2022] Open
Abstract
SETTING Khayelitsha, South Africa, with high burdens of rifampicin-resistant tuberculosis (RR-TB) and HIV co-infection. OBJECTIVE To describe time to antiretroviral treatment (ART) initiation among HIV-infected RR-TB patients initiating RR-TB treatment and to assess the association between time to ART initiation and treatment outcomes. DESIGN A retrospective cohort study of patients with RR-TB and HIV co-infection not on ART at RR-TB treatment initiation. RESULTS Of the 696 RR-TB and HIV-infected patients initiated on RR-TB treatment between 2009 and 2013, 303 (44%) were not on ART when RR-TB treatment was initiated. The median CD4 cell count was 126 cells/mm3. Overall 257 (85%) patients started ART during RR-TB treatment, 33 (11%) within 2 weeks, 152 (50%) between 2-8 weeks and 72 (24%) after 8 weeks. Of the 46 (15%) who never started ART, 10 (21%) died or stopped RR-TB treatment within 4 weeks and 16 (37%) had at least 4 months of RR-TB treatment. Treatment success and mortality during treatment did not vary by time to ART initiation: treatment success was 41%, 43%, and 50% among patients who started ART within 2 weeks, between 2-8 weeks, and after 8 weeks (p = 0.62), while mortality was 21%, 13% and 15% respectively (p = 0.57). Mortality was associated with never receiving ART (adjusted hazard ratio (aHR) 6.0, CI 2.1-18.1), CD4 count ≤100 (aHR 2.1, CI 1.0-4.5), and multidrug-resistant tuberculosis (MDR-TB) with second-line resistance (aHR 2.5, CI 1.1-5.4). CONCLUSIONS Despite wide variation in time to ART initiation among RR-TB patients, no differences in mortality or treatment success were observed. However, a significant proportion of patients did not initiate ART despite receiving >4 months of RR-TB treatment. Programmatic priorities should focus on ensuring all patients with RR-TB/HIV co-infection initiate ART regardless of CD4 count, with special attention for patients with CD4 counts ≤ 100 to initiate ART as soon as possible after RR-TB treatment initiation.

Building operational research capacity in the Pacific. Public Health Action 2015; 4:S2-S13. [PMID: 26477282 DOI: 10.5588/pha.13.0091] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2013] [Accepted: 01/27/2014] [Indexed: 11/10/2022] Open
Abstract
Operational research (OR) in public health aims to investigate strategies, interventions, tools or knowledge that can enhance the quality, coverage, effectiveness or performance of health systems. Attention has recently been drawn to the lack of OR capacity in public health programmes throughout the Pacific Islands, despite considerable investment in implementation. This lack of ongoing and critical reflection may prevent health programme staff from understanding why programme objectives are not being fully achieved, and hinder long-term gains in public health. The International Union Against Tuberculosis and Lung Disease (The Union) has been collaborating with Pacific agencies to conduct OR courses based on the training model developed by The Union and Médecins Sans Frontières Brussels-Luxembourg in 2009. The first of these commenced in 2011 in collaboration with the Fiji National University, the Fiji Ministry of Health, the World Health Organization and other partners. The Union and the Secretariat of the Pacific Community organised a second course for participants from other Pacific Island countries and territories in 2012, and an additional course for Fijian participants commenced in 2013. Twelve participants enrolled in each of the three courses. Of the two courses completed by end 2013, 18 of 24 participants completed their OR and submitted papers by the course deadline, and 17 papers have been published to date. This article describes the context, process and outputs of the Pacific courses, as well as innovations, adaptations and challenges.

Abstract
In 2009, the International Union Against Tuberculosis and Lung Disease (The Union) and Médecins sans Frontières Brussels-Luxembourg (MSF) began developing an outcome-oriented model for operational research training. In January 2013, The Union and MSF joined with the Special Programme for Research and Training in Tropical Diseases (TDR) at the World Health Organization (WHO) to form an initiative called the Structured Operational Research and Training Initiative (SORT IT). This integrates the training of public health programme staff with the conduct of operational research prioritised by their programme. SORT IT programmes consist of three one-week workshops over 9 months, with clearly-defined milestones and expected output. This paper describes the vision, objectives and structure of SORT IT programmes, including selection criteria for applicants, the research projects that can be undertaken within the time frame, the programme structure and milestones, mentorship, the monitoring and evaluation of the programmes and what happens beyond the programme in terms of further research, publications and the setting up of additional training programmes. There is a growing national and international need for operational research and related capacity building in public health. SORT IT aims to meet this need by advocating for the output-based model of operational research training for public health programme staff described here. It also aims to secure sustainable funding to expand training at a global and national level. Finally, it could act as an observatory to monitor and evaluate operational research in public health. Criteria for prospective partners wishing to join SORT IT have been drawn up.

Abstract
Open-access journal publications aim to ensure that new knowledge is widely disseminated and made freely accessible in a timely manner so that it can be used to improve people's health, particularly those in low- and middle-income countries. In this paper, we briefly explain the differences between closed- and open-access journals, including the evolving idea of the 'open-access spectrum'. We highlight the potential benefits of supporting open access for operational research, and discuss the conundrum and ways forward as regards who pays for open access.

Abstract
SETTING One hundred and forty non-governmental organisations implementing human immunodeficiency virus (HIV) prevention programmes among clients, including people who inject drugs, prisoners, female sex workers, men who have sex with men and street children in Ukraine, 2010-2011. OBJECTIVE Among enrolled clients, to assess factors associated with HIV testing, HIV retesting within a year of initial testing and HIV seroconversion. DESIGN Retrospective cohort study involving record reviews. RESULTS Of 192 487 clients, 42 109 (22%) underwent an initial HIV test (22% were positive). Among HIV-negative clients at baseline, 10 858 (27%) were retested within a year: 317 (3%) of these were HIV-positive. HIV testing and retesting rates were lower among prisoners (0.3%) and others (street children and partners of those in risk groups, 6%), and those who did not receive counselling or services such as condom and needle distribution. Individuals who were not counselled were more likely to seroconvert. CONCLUSIONS In this large cohort of high-risk groups from Eastern Europe, HIV testing was low and HIV sero-conversion was high. This is of public health concern, bringing into question the overall quality of counselling and how well it is tailored to the specific needs of various risk groups. Qualitative studies to understand the reasons for non-testing are urgently required for designing client-specific interventions.

Abstract
SETTING One reference and three zonal laboratories and 500 health facilities managing retreatment tuberculosis (TB) patients in Tanzania. OBJECTIVES The National Tuberculosis and Leprosy Programme (NTLP) requires that all notified cases of retreatment TB in Tanzania have sputum samples sent for culture and drug susceptibility testing (DST). This study determined 1) if the number of annually notified retreatment patients corresponded to the number of sputum samples received by the reference laboratories, and 2) the number of culture-positive samples and the number of cases undergoing DST. DESIGN Nine-year audit of country-wide programme data from 2002 to 2010. RESULTS Of the 40 940 retreatment TB patients notified by the NTLP, 3871 (10%) had their sputum samples received at the reference and zonal laboratories for culture and DST. A total of 3761 (97%) sputum samples were processed for culture, of which 1589 (42%) were found to be culture-positive and 1415 (89%) had DST performed. CONCLUSIONS There is a >90% shortfall between notified retreatment cases and numbers of sputum samples received, cultured and assessed for DST at reference and zonal laboratories. Steps needed to address this problem are discussed.

Abstract
SETTINGS Tuberculosis (TB) health facilities in the Gomel Region, Republic of Belarus-settings with a high burden of multidrug-resistant TB (MDR-TB) and human immunodeficiency virus (HIV) infection. OBJECTIVE To determine treatment outcomes among MDR-TB patients diagnosed in 2009-2010 and factors associated with unsuccessful outcomes (death, failure and loss to follow-up). DESIGN Retrospective cohort study involving a review of an electronic patient database maintained under the National Tuberculosis Control Programme. RESULTS Of 517 patients diagnosed, 78 (15%) did not start treatment. Among 439 patients who started treatment (84% males, median age 45 years, 15% HIV-infected), 291 (66%) had unsuccessful outcomes (35% deaths, 18% treatment failure and 13% lost to follow-up). Multivariate regression analysis showed that patients aged ⩾45 years (aRR 1.2, 95%CI 1.1-1.3), HIV-infected patients and those not receiving antiretroviral therapy (ART) (aRR 1.5, 95%CI 1.4-1.6) and those with a previous history of anti-tuberculosis treatment (aRR 1.2, 95%CI 1.1-1.4) had significantly higher risk of unsuccessful outcomes. CONCLUSION Treatment outcomes among MDR-TB patients were poor, with high rates of death, failure and loss to follow-up (including pre-treatment loss to follow-up). Urgent measures to increase ART uptake among HIV-infected MDR-TB patients, improved access to second-line anti-tuberculosis drug susceptibility testing and comprehensive patient support measures are required to address this grim situation.

Abstract
SETTING A rural paediatric hospital in Bo, Sierra Leone. OBJECTIVES To assess the level of adherence to standard treatment guidelines among clinicians prescribing treatment for children admitted with a diagnosis of malaria and/or lower respiratory tract infection (LRTI), and determine the association between (non) adherence and hospital outcomes, given that non-rational use of medicines is a serious global problem. DESIGN Secondary analysis of routine programme data. RESULTS Data were collected for 865 children admitted with an entry diagnosis of malaria and 690 children with LRTI during the period January to April 2011; some patients were classified in both categories. Non-adherence to guidelines comprised use of non-standard drug regimens, dosage variations, non-standard frequency of administration and treatment duration. Cumulative non-adherence to guidelines for LRTI cases was 86%. For malaria, this involved 12% of patients. Potentially harmful non-adherence was significantly associated with an unfavourable hospital outcome, both for malaria and for LRTI cases. CONCLUSIONS Overall non-adherence to standard treatment guidelines by clinicians in a routine hospital setting is very high and influences hospital outcomes. This study advocates for the implementation of routine measures to monitor and improve rational drug use and the quality of clinical care in such hospitals.

Abstract
SETTING An antenatal clinic serving a population of 47 604 in Nausori, Fiji. OBJECTIVE 1) To estimate the prevalence of anaemia, syphilis and hepatitis B in pregnant women attending their first antenatal visit; and 2) to estimate the uptake of treatment for syphilis and for the prevention of hepatitis B transmission in affected individuals. DESIGN Retrospective review of the clinic register and patient records for the year 2011. RESULTS The prevalence of anaemia, hepatitis B and syphilis were respectively 22%, 2% and 5%. Among women with syphilis, 78% of those for whom data were available received a complete course of three doses of penicillin during their pregnancy, and 83% of babies born to women with hepatitis B received hepatitis B immunoglobulin. CONCLUSION The prevalence of anaemia in pregnant women has declined but remains high, and further research is required to identify the major causes of this condition in Fiji. The prevalence of syphilis has remained static, while hepatitis B has decreased over the past decade. There are some gaps in the implementation of effective interventions to manage these conditions in pregnant women.

Abstract
We assessed the performance of decentralised tuberculosis (TB) out-patient centres in tuberculosis (TB) case notification and treatment success in Armenia. An average threshold case notification of ⩾37/100 000 was seen in centres that had higher numbers of presumptive TB patients, where more TB was diagnosed by in-patient facilities and where TB contacts were examined. The number of doctors and/or TB specialists at centres did not influence case notification. Onsite smear microscopy was significantly associated with a treatment success rate of ⩾85% for new TB patients. Addressing specific characteristics of TB centres associated with lower case notification and treatment success and optimising their location may improve performance.

Abstract
SETTING Latvia, an Eastern European country with a high burden of tuberculosis (TB). OBJECTIVE To describe treatment outcomes among new drug-susceptible TB patients and assess the association of treatment outcomes with selected social determinants and risk factors. DESIGN A retrospective cohort study of patients aged ⩾15 years registered during 2006-2010, with a review of records in the National Tuberculosis Registry. RESULTS Of 2476 patients, 1704 (69%) were male; the median age was 42 years. About two thirds of patients were unemployed or retired, 7% were human immunodeficiency virus (HIV) positive and 35% had a history of alcohol use. Treatment success was achieved in 2167 (88%) patients. Older age, unemployment, HIV infection and alcohol use were found to be independently associated with unsuccessful treatment (death, loss to follow-up, failure, transfer out and other). For many variables, including HIV infection, diabetes mellitus and tobacco use, it was not possible to distinguish between 'not recorded' and 'not present' in the registry. CONCLUSION The treatment success rate among new drug-susceptible TB patients exceeded the 85% global target for TB control. Additional attention and support is required for most vulnerable patients, such as those who are unemployed or retired, HIV infected and alcohol users. The National TB Registry should be revised to improve definitions and staff should be trained for proper data collection and recording.

Access to CD4 Testing for Rural HIV Patients: Findings from a Cohort Study in Zimbabwe. PLoS One 2015; 10:e0129166.

Abstract
Background CD4 cell count measurement remains an important diagnostic tool for HIV care in developing countries. Insufficient laboratory capacity in rural Sub-Saharan Africa is frequently mentioned but data on the impact at an individual patient level are lacking. Urban-rural discrepancies in CD4 testing have not been quantified to date. Such evidence is crucial for public health planning and to justify new yet more expensive diagnostic procedures that could circumvent access constraints in rural areas. Objective To compare CD4 testing among rural and urban HIV patients during the first year of treatment. Methods Records from 2,145 HIV positive adult patients from a Médecins sans Frontières (Doctors without Borders) HIV project in Beitbridge, Zimbabwe, during 2011 and 2012 were used for a retrospective cohort analysis. Covariate-adjusted risk ratios were calculated to estimate the effects of area of residence on CD4 testing at treatment initiation, six and 12 months among rural and urban patients. Findings While the proportion of HIV patients returning for medical consultations at six and 12 months decreased at a similar rate in both patient groups, CD4 testing during consultations dropped to 21% and 8% for urban, and 2% and 1% for rural patients at six and 12 months, respectively. Risk ratios for missing CD4 testing were 0.8 (95% CI 0.7-0.9), 9.2 (95% CI 5.5-15.3), and 7.6 (95% 3.7-17.1) comparing rural versus urban patients at treatment initiation, six and 12 months, respectively. Conclusions CD4 testing was low overall, and particularly poor in rural patients. Difficulties with specimen transportation were probably a major factor underlying this difference and requires new diagnostic approaches. Our findings point to severe health system constraints in providing CD4 testing overall that need to be addressed if effective monitoring of HIV patients is to be achieved, whether by alternative CD4 diagnostics or newly-recommended routine viral load testing.

Factors associated with virological failure and suppression after enhanced adherence counselling, in children, adolescents and adults on antiretroviral therapy for HIV in Swaziland. PLoS One 2015; 10:e0116144. [PMID: 25695494 PMCID: PMC4335028 DOI: 10.1371/journal.pone.0116144] [Citation(s) in RCA: 133] [Impact Index Per Article: 14.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2014] [Accepted: 12/03/2014] [Indexed: 11/18/2022] Open
Abstract
INTRODUCTION This study explores factors associated with virological detectability, and viral re-suppression after enhanced adherence counselling, in adults and children on antiretroviral therapy (ART) in Swaziland. METHODS This descriptive study used laboratory data from 7/5/2012 to 30/9/2013, which were linked with the national ART database to provide information on time on ART and CD4 count; information on enhanced adherence counselling was obtained from file review in health facilities. Multivariable logistic regression was used to explore the relationship between viral load, gender, age, time on ART, CD4 count and receiving (or not receiving) enhanced adherence counselling. RESULTS From 12,063 patients undergoing routine viral load monitoring, 1941 (16%) had detectable viral loads. Children were more likely to have detectable viral loads (AOR 2.6, 95%CI 1.5-4.5), as were adolescents (AOR 3.2, 95%CI 2.2-4.8), patients with last CD4<350 cells/µl (AOR 2.2, 95%CI 1.7-2.9) or WHO Stage 3/4 disease (AOR 1.3, 95%CI 1.1-1.6), and patients on ART for longer (AOR 1.1, 95%CI 1.1-1.2). At retesting, 450 (54% of those tested) showed viral re-suppression. Children were less likely to re-suppress (AOR 0.2, 95%CI 0.1-0.7), as were adolescents (AOR 0.3, 95%CI 0.2-0.8), those with initial viral load> 1000 copies/ml (AOR 0.3, 95%CI 0.1-0.7), and those with last CD4<350 cells/µl (AOR 0.4, 95%CI 0.2-0.7). Receiving (or not receiving) enhanced adherence counselling was not associated with likelihood of re-suppression. CONCLUSIONS Children, adolescents and those with advanced disease were most likely to have high viral loads and least likely to achieve viral suppression at retesting; receiving adherence counselling was not associated with higher likelihood of viral suppression. Although the level of viral resistance was not quantified, this study suggests the need for ART treatment support that addresses the adherence problems of younger people; and to define the elements of optimal enhanced adherence support for patients of all ages with detectable viral loads.

[PMID: 26090033 PMCID: PMC4450040 DOI: 10.11604/pamj.2015.20.75.4696] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Accepted: 01/15/2015] [Indexed: 12/27/2022] Open
Abstract
Introduction Infective endocarditis is an infection of the endocardial lining of the heart mainly associated with congenital and rheumatic heart disease. Although it is a rare disease in children, it is associated with high morbidity and mortality; death due to infective endocarditis has been reported to be as high as 26% in sub-Saharan Africa. Methods This was a retrospective review of routinely collected data from patient records. Results A total of 40 children (71% female) with 41 episodes of infective endocarditis admitted to a general paediatric ward in Addis Ababa, Ethiopia between 2008 and 2013. Age ranged from 7 months to 14 years, with a median of 9 years (Inter quartile Range: 7-12 years). Rheumatic and congenital heart diseases were underlying risk factors in 49% and 51% of cases respectively. Congestive heart failure, systemic embolization and death occurred in 66%, 12% and 7.3% respectively. Death was associated with the occurrence of systemic embolization (P-value = 0.03). Conclusion Rheumatic heart disease was an important predisposing factor for infective endocarditis in Ethiopian children. Late presentations of cases were evidenced by high proportion of complications such as congestive heart failure. A low rate of clinically evident systemic embolization in this study may be a reflection of the diagnostic challenges. High proportion of prior antibiotic intake might explain the cause of significant BCNE. Preventive measures like primary and secondary prophylaxis of rheumatic fever may decrease the associated morbidity and mortality. Early detection and referral of cases, awareness creation about indiscriminate use of antimicrobials, and proper history taking and documentation of information recommended.

Operational research capacity building using 'The Union/MSF' model: adapting as we go along. BMC Res Notes 2014; 7:819. [PMID: 25409542 PMCID: PMC4253003 DOI: 10.1186/1756-0500-7-819] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2014] [Accepted: 11/06/2014] [Indexed: 11/29/2022] Open
Abstract
Background We have conducted 23 operational research (OR) courses since 2009, based on ‘The Union/ Médecins Sans Frontières (MSF)’ model, now popularly known as SORT-IT (Structured Operational Research and Training Initiative) model - wherein participants are mentored through the whole research process from protocol development (module 1) to data analysis (module 2) to publication (module 3) over a period of 9–12 months. We have faced a number of challenges including shortage of time, especially for data analysis and interpretation, and a heavy mentorship burden on limited numbers of experienced facilitators. To address these challenges, we have made several modifications to the structure of the OR course. In this article, we describe the revised structure and our experience (successes and challenges) of implementing it in Asia in 2013. Findings The key changes introduced included extending the duration of the course modules (by a day each in module 1 and 2 and by three days in module 3), increasing the numbers of facilitators and standardizing milestones related to data entry and analysis. We successfully implemented this revised structure in the second Asian OR Course held in Nepal in 2013. Eleven of twelve participants successfully completed all the milestones and submitted 13 scientific manuscripts (two participants completed two projects) to international peer-reviewed journals. Though, this posed two challenges – increased costs and increased time away for faculty and participants. Conclusions The revised structure of ‘The Union/MSF’ model of OR capacity building addressed previous issues of insufficient time and overburdened mentors and we intend to continue with this model for future courses.

Risk factors associated with loss to follow-up among multidrug-resistant tuberculosis patients in Georgia. Public Health Action 2014; 4:S41-6. [PMID: 26393097 PMCID: PMC4547510 DOI: 10.5588/pha.14.0048] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2014] [Accepted: 08/22/2014] [Indexed: 11/10/2022] Open
Abstract
SETTING Georgia, a country with a high-burden of multi-drug-resistant tuberculosis (MDR-TB). OBJECTIVE To determine the proportion of loss to follow-up (LFU) among MDR-TB patients treated nationwide from 2009 to 2011, and associated risk factors. DESIGN Retrospective cohort study involving a review of the National Tuberculosis Programme electronic surveillance database. A Cox proportional hazards model was used to assess risk factors for time to LFU. RESULTS Among 1593 patients, 458 (29%) were lost to follow-up. A total of 1240 MDR-TB patients were included in the final analysis (845 treatment success, 395 LFU). Over 40% of LFU occurred during the first 8 months of MDR-TB treatment; 40% of patients had not achieved culture conversion at the time of LFU. In multivariate analysis, the factors associated with LFU included male sex, illicit drug use, tobacco use, history of previous anti-tuberculosis treatment, site of TB disease, and place and year of initiating treatment. CONCLUSION LFU was high among MDR-TB patients in Georgia and posed a significant public health risk, as many were culture-positive at the time of LFU. A multi-pronged approach is needed to address the various patient- and treatment-related characteristics associated with LFU.

How well are asthma treatment cards filled out in public health centres in Gazeera State, Sudan? Public Health Action 2014; 4:116-21. [PMID: 26399211 PMCID: PMC4539030 DOI: 10.5588/pha.14.0004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2014] [Accepted: 04/29/2014] [Indexed: 11/10/2022] Open
Abstract
SETTING Four public district hospitals offering asthma treatment in Gazeera State, Sudan. Incomplete recording of patient data directly affects the quality of asthma care and the evaluation of asthma management programmes. OBJECTIVE To assess the completeness of filling out of treatment cards and accuracy of calculating peak expiratory flow (PEF) for confirming diagnosis and grading severity of asthma. DESIGN Cross-sectional audit of asthma treatment cards from asthma centres, 2006-2012. RESULTS Of 959 patient cards assessed, completeness ranged from 47% to 98%. Six of 13 variables had an unsatisfactory grade of completeness (<80% complete). Calculated PEF was indicated in 885 (92%) cards, but was correct in only 609 (69%). PEF variability was recorded in 835 (87%) cards, but was correctly calculated in 442 (53%). A scheduled follow-up visit was attended by only 359 (37%) patients, indicating 63% loss to follow-up. Contact telephone numbers were missing from 453 (47%) cards. CONCLUSION This is the first study in Africa to assess the data completeness and integrity of asthma patient cards, identifying important shortcomings. This affects quality of management of asthma patients and programme evaluation. Steps to rectify this situation are urgently needed.
