Factors associated with influenza-like illness in care homes in Cheshire and Merseyside during the 2017-2018 influenza season.

OBJECTIVES: The aim of the study was to identify care home characteristics associated with reported care home influenza outbreaks and factors associated with increased transmission of influenza-like illness (ILI) in care homes in Cheshire and Merseyside during the 2017-2018 influenza season. STUDY DESIGN: This is a matched case-control study comparing characteristics between care homes with and without a declared influenza outbreak and a retrospective risk factor analysis of care home residents with ILI. METHODS: Routinely collected outbreak surveillance data on symptomatic residents and staff, antiviral prophylaxis and influenza vaccination history, which were reported to Public Health England, were extracted from health protection electronic records. Further care home characteristics were extracted from the Care Quality Commission (CQC) website. Care homes with declared influenza outbreaks were matched with care homes without outbreaks. Chi-squared tests and logistic regression were used to examine associations between care home factors and ILI. RESULTS: There were no significant differences in characteristics between 77 care homes with declared influenza outbreaks and 77 matched care homes without outbreaks. Of 2,744 residents from the homes with a declared outbreak, 644 (24%) developed an ILI. The care home risk factors were having a low CQC score and activation of antiviral prophylaxis and the protective factors were having higher numbers of residents, specializing in dementia care and having the highest CQC score. Significantly more cases occurred in residential homes than in nursing homes, in homes with lower CQC scores and in homes where eligible residents were given antiviral prophylaxis. CONCLUSIONS: In homes with declared outbreaks, certain characteristics including activation of antiviral prophylaxis were associated with an increased risk of ILI. Further research is needed, particularly focussing on temporality between provision of prophylactic antivirals and the onset of ILI.

Use of prophylactic antivirals and care home characteristics associated with influenza in care homes with confirmed outbreaks.

OBJECTIVES: To assess the association of antiviral prophylaxis and care home characteristics with the spread and severity of influenza-like illness in care homes with influenza outbreaks in North West England in the 2017/2018 influenza season. STUDY DESIGN: This is a retrospective observational study. METHODS: Routinely collected outbreak surveillance data reported to Public Health England were extracted from health protection electronic records. Data included use of antiviral prophylaxis, influenza-like illness or confirmed influenza, hospital admissions and deaths. Care home characteristics were obtained from the Care Quality Commission website. Single variable analysis and multivariable logistic regression were used to examine associations between care home characteristics, antiviral prophylaxis and influenza-related outcomes. RESULTS: In the 109 homes, there were 3498 residents; of whom, 855 (24%) developed an influenza-like illness. Antiviral prophylaxis was given to residents of 67 of the 109 care homes with outbreaks (61%). A significantly higher attack rate was observed among residents of homes given antiviral prophylaxis (27%) than among residents of homes not given antivirals (20%) (P < 0.001). Significantly more deaths occurred in homes for people with learning disabilities and homes that received antiviral prophylaxis (P < 0.001). CONCLUSIONS: In homes given antiviral prophylaxis, there were a higher number of residents with influenza-like illness and deaths. To improve our understanding of the impact of antiviral prophylaxis use in real life, enhanced and timely data collection is needed for identification of temporal associations between exposure and administration of antiviral prophylaxis. Consideration needs also to be given to ensure people with learning disabilities are protected through the seasonal influenza vaccine and timely antiviral prophylaxis when appropriate.

Cost of hospitalisation for non-communicable diseases in India: are we pro-poor?

OBJECTIVES: To estimate out-of-pocket (OOP) expenditure due to hospitalisation from NCDs and its impact on households in India. METHODS: The study analysed nationwide representative data collected by the National Sample Survey Organisation in 2014 that reported health service utilisation and healthcare-related OOP expenditure by income quintiles and by type of health facility (public or private). The recall period for inpatient hospitalisation expenditure was 365 days. Consumption expenditure was collected for a recall period of 1 month. OOP expenditure amounting to >10% of annual consumption expenditure was termed as catastrophic. Weighted analysis was performed. RESULTS: The median expenditure per episode of hospitalisation due to NCDs was USD 149 - this was ~3 times higher among the richest quintile compared to poorest quintile. There was a significantly higher prevalence of catastrophic expenditure among the poorest quintile, more so for cancers (85%), psychiatric and neurological disorders (63%) and injuries (63%). Mean private-sector OOP hospitalisation expenditure was nearly five times higher than that in the public sector. Medicines accounted for 40% and 27% of public- and private-sector OOP hospitalisation expenditure, respectively. CONCLUSION: Strengthening of public health facilities is required at community level for the prevention, control and management of NCDs. Promotion of generic medicines, better availability of essential drugs and possible subsidisation for the poorest quintile will be measures to consider to reduce OOP expenditure in public-sector facilities.

Hypertension and treatment outcomes in Palestine refugees in United Nations Relief and Works Agency primary health care clinics in Jordan.

OBJECTIVE: In six United Nations Relief and Works Agency (UNRWA) primary health care clinics in Jordan serving Palestine refugees diagnosed with hypertension, to determine the number, characteristics, programme outcomes and measures of disease control for those registered up to 30 June, 2013, and in those who attended clinic in the second quarter of 2013, the prevalence of disease-related complications between those with hypertension only and hypertension combined with diabetes mellitus. METHOD: Retrospective cohort study with programme and outcome data collected and analysed using E-Health. RESULTS: There were 18 881 patients registered with hypertension with females (64%) and persons aged ≥ 40 years (87%) predominating. At baseline, cigarette smoking was recorded in 17%, physical inactivity in 48% and obesity in 71% of patients. 77% of all registered patients attended clinic in the second quarter of 2013; of these, 50% had hypertension and diabetes and 50% had hypertension alone; 9% did not attend the clinics and 10% were lost to follow-up. Amongst those attending clinic, 92% had their blood pressure measured, of whom 83% had blood pressure <140/90 mm Hg. There were significantly more patients with hypertension and diabetes (N = 966, 13%) who had disease-related complications than patients who had hypertension alone (N = 472, 6%) [OR 2.2, 95% CI 2.0-2.5], and these differences were found for both males [18% vs. 10%, OR 1.9, 95% CI 1.6-2.2] and females [11% vs. 5%, OR 2.4, 95% CI 2.1-2.9]. CONCLUSION: Large numbers of Palestine refugees are being registered and treated for hypertension in UNRWA primary health care clinics in Jordan. Cohort analysis and E-Health can be used to regularly assess caseload, programme outcomes, clinic performance, blood pressure control and cumulative prevalence of disease-related complications. Current challenges include the need to increase clinic attendance and attain better control of blood pressure.

Timeliness metrics for screening and preventing TB in household contacts of pulmonary TB patients in Kenya.

BACKGROUND: The study assessed whether a "7-1-7" timeliness metric for screening and TB preventive therapy (TPT) could be implemented for household contacts (HHCs) of index patients with bacteriologically confirmed pulmonary TB under routine programmatic settings in Kenya. METHODS: A longitudinal cohort study conducted among index patients and their HHCs in 12 health facilities, Kiambu County, Kenya. RESULTS: Between January and June 2023, 95% of 508 index patients had their HHCs line-listed within 7 days of initiating anti-TB treatment ("First 7"). In 68% of 1,115 HHCs, screening outcomes were ascertained within 1 day of line-listing ("Next 1"). In 65% of 1,105 HHCs eligible for further evaluation, anti-TB treatment, TPT or a decision for no drugs was made within 7 days of screening ("Second 7"). Altogether, 62% of screened HHCs started TPT during the "7-1-7" period compared with 58% in a historical cohort. Main barriers to TPT uptake were HHCs not consulting clinicians, HHCs being unwilling to initiate TPT and drug shortages. Healthcare workers felt that a timeliness metric was valuable for streamlining HHC management and proposed "3-5-7" as a workable alternative. CONCLUSIONS: The national TB programme must generate awareness about TPT, ensure uninterrupted drug supplies and assess whether the "3-5-7" metric can be operationalised.

CONTEXTE: L'étude a évalué si une mesure de rapidité "7-1-7" pour le dépistage et le traitement préventif de la TB (TPT) pouvait être mise en œuvre pour les contacts familiaux des patients index atteints de TB pulmonaire confirmée bactériologiquement dans le cadre d'un programme de routine au Kenya. MÉTHODES: Étude de cohorte longitudinale menée auprès de patients index et de leurs contacts familiaux dans 12 établissements de santé du comté de Kiambu, au Kenya. RÉSULTATS: Entre janvier et juin 2023, 95% des 508 patients index ont eu leur centre de santé inscrit sur la liste dans les 7 jours suivant le début du traitement antituberculeux (« First 7 ¼ ). Dans 68% des 1 115 centres de santé, les résultats du dépistage ont été vérifiés dans le jour suivant l'inscription sur la liste (« Next 1 ¼). Dans 65% des 1 105 centres de santé éligibles pour une évaluation plus approfondie, le traitement antituberculeux, le TPT ou la décision de ne pas prendre de médicaments a été prise dans les 7 jours suivant le dépistage (« Second 7 ¼). Au total, 62% des patients dépistés ont commencé un traitement antituberculeux au cours de la période « 7-1-7 ¼, contre 58% dans une cohorte historique. Les principaux obstacles à l'adoption du TPT étaient les suivants : les centres de santé ne consultaient pas les cliniciens, les centres de santé n'étaient pas disposés à commencer le TPT et les pénuries de médicaments. Les professionnels de la santé ont estimé qu'une mesure de la rapidité d'exécution était utile pour rationaliser la gestion des centres de santé et ont proposé le « 3-5-7 ¼ comme solution de rechange viable. CONCLUSION: Le programme national de lutte contre la TB doit sensibiliser au TPT, garantir un approvisionnement ininterrompu en médicaments et évaluer si la mesure « 3-5-7 ¼ peut être mise en œuvre.

Using timeliness metrics for household contact tracing and TB preventive therapy in the private sector, India.

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.This was an explanatory mixed-methods study (quantitative-cohort and qualitative-descriptive).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.Introduction of a timeliness metric is a workable intervention that adds structure to HHC screening and timely management..

Diagnosis of pulmonary tuberculosis in a pastoralist population in Ethiopia: are three sputum specimens needed?

OBJECTIVE: To assess the number of sputum specimens necessary for a reliable diagnosis of pulmonary tuberculosis (PTB) in a pastoralist population in Ethiopia. METHOD: Using routine data from Ethiopia, where three sputum specimens are currently recommended for the diagnosis of PTB, we documented, (i) the proportion of persons with suspected, PTB who submitted a first, second and third sputum specimen for smear examination and (ii) the incremental smear-positive yield from the first, to the second and third specimens. RESULTS: Of 505 persons with suspected PTB, 107 (22%) failed to submit three samples. Of 60 patients who submitted three sputum samples with at least one smear-positive sample, the first sputum sample was smear positive in 56 (93%) cases; the second sputum sample was the first to be positive in 3 (5%) cases and in only one case was the third sample the first to be smear positive (additional yield 2%). CONCLUSION: In a pastoralist setting, a reliable diagnosis of PTB can be achieved with two sputum specimens and PTB diagnosis may be adequate with just one sputum specimen. However, if this more radical approach was adopted, ways of increasing diagnostic sensitivity should be explored.

Village registers for vital registration in rural Malawi.

Paper-based village registers were introduced 5 years ago in Malawi as a tool to measure vital statistics of births and deaths at the population level. However, usage, completeness and accuracy of their content have never been formally evaluated. In Traditional Authority Mwambo, Zomba district, Malawi, we assessed 280 of the 325 village registers with respect to (i) characteristics of village headmen who used village registers, (ii) use and content of village registers, and (iii) whether village registers provided accurate information on births and deaths. All village headpersons used registers. There were 185 (66%) registers that were regarded as 95% completed, and according to the registers, there were 115 840 people living in the villages in the catchment area. In 2011, there were 1753 births recorded in village registers, while 6397 births were recorded in health centre registers in the same catchment area. For the same year, 199 deaths were recorded in village registers, giving crude death rates per 100 000 population of 189 for males and 153 for females. These could not be compared with death rates in health centre registers due to poor and inconsistent recording in these registers, but they were compared with death rates obtained from the 2010 Malawi Demographic Health Survey that reported 880 and 840 per 100 000 for males and females, respectively. In conclusion, this study shows that village registers are a potential source for vital statistics. However, considerable inputs are needed to improve accuracy of births and deaths, and there are no functional systems for the collation and analysis of data at the traditional authority level. Innovative ways to address these challenges are discussed, including the use of solar-powered electronic village registers and mobile phones, connected with each other and the health facilities and the District Commissioner's office through the cellular network and wireless coverage.

An ambulance referral network improves access to emergency obstetric and neonatal care in a district of rural Burundi with high maternal mortality.

OBJECTIVES: In 2006, Médecins sans Frontières (MSF) established an emergency obstetric and neonatal care (EmONC) referral facility linked to an ambulance referral system for the transfer of women with obstetric complications from peripheral maternity units in Kabezi district, rural Burundi. This study aimed to (i) describe the communication and ambulance service together with the cost; (ii) examine the association between referral times and maternal and early neonatal deaths; and (iii) assess the impact of the referral service on coverage of complicated obstetric cases and caesarean sections. METHODS: Data were collected for the period January to December 2011, using ambulance log books, patient registers and logistics records. RESULTS: In 2011, there were 1478 ambulance call-outs. The median referral time (time from maternity calling for an ambulance to the time the patient arrived at the MSF referral facility) was 78 min (interquartile range, 52-130 min). The total annual cost of the referral system (comprising 1.6 ambulances linked with nine maternity units) was € 85 586 (€ 61/obstetric case transferred or € 0.43/capita/year). Referral times exceeding 3 h were associated with a significantly higher risk of early neonatal deaths (OR, 1.9; 95% CI, 1.1-3.2). MSF coverage of complicated obstetric cases and caesarean sections was estimated to be 80% and 92%, respectively. CONCLUSION: This study demonstrates that it is possible to implement an effective communication and transport system to ensure access to EmONC and also highlights some of the important operational factors to consider, particularly in relation to minimising referral delays.

Achieving the millennium development goal of reducing maternal mortality in rural Africa: an experience from Burundi.

OBJECTIVES: To estimate the reduction in maternal mortality associated with the emergency obstetric care provided by Médecins Sans Frontières (MSF) and to compare this to the fifth Millennium Development Goal of reducing maternal mortality. METHODS: The impact of MSF's intervention was approximated by estimating how many deaths were averted among women transferred to and treated at MSF's emergency obstetric care facility in Kabezi, Burundi, with a severe acute maternal morbidity. Using this estimate, the resulting theoretical maternal mortality ratio in Kabezi was calculated and compared to the Millennium Development Goal for Burundi. RESULTS: In 2011, 1385 women from Kabezi were transferred to the MSF facility, of whom 55% had a severe acute maternal morbidity. We estimated that the MSF intervention averted 74% (range 55-99%) of maternal deaths in Kabezi district, equating to a district maternal mortality rate of 208 (range 8-360) deaths/100,000 live births. This lies very near to the 2015 MDG 5 target for Burundi (285 deaths/100,000 live births). CONCLUSION: Provision of quality emergency obstetric care combined with a functional patient transfer system can be associated with a rapid and substantial reduction in maternal mortality, and may thus be a possible way to achieve Millennium Development Goal 5 in rural Africa.

Practicing medicine without borders: tele-consultations and tele-mentoring for improving paediatric care in a conflict setting in Somalia?

OBJECTIVES: In a district hospital in conflict-torn Somalia, we assessed (i) the impact of introducing telemedicine on the quality of paediatric care, and (ii) the added value as perceived by local clinicians. METHODS: A 'real-time' audio-visual exchange of information on paediatric cases (Audiosoft Technologies, Quebec, Canada) took place between clinicians in Somalia and a paediatrician in Nairobi. The study involved a retrospective analysis of programme data, and a perception study among the local clinicians. RESULTS: Of 3920 paediatric admissions, 346 (9%) were referred for telemedicine. In 222 (64%) children, a significant change was made to initial case management, while in 88 (25%), a life-threatening condition was detected that had been initially missed. There was a progressive improvement in the capacity of clinicians to manage complicated cases as demonstrated by a significant linear decrease in changes to initial case management for meningitis and convulsions (92-29%, P = 0.001), lower respiratory tract infection (75-45%, P = 0.02) and complicated malnutrition (86-40%, P = 0.002). Adverse outcomes (deaths and lost to follow-up) fell from 7.6% in 2010 (without telemedicine) to 5.4% in 2011 with telemedicine (30% reduction, odds ratio 0.70, 95% CI: 0.57-0.88, P = -0.001). The number needed to be treated through telemedicine to prevent one adverse outcome was 45. All seven clinicians involved with telemedicine rated it to be of high added value. CONCLUSION: The introduction of telemedicine significantly improved quality of paediatric care in a remote conflict setting and was of high added value to distant clinicians.

Antimicrobial resistance in bacteria isolated from the poultry production system in Nepal.

SETTING: Twenty poultry farms in five provinces of Nepal were selected for studying bacterial pathogens and their antimicrobial resistance (AMR) patterns. OBJECTIVE: To document the proportion of cloacal swabs collected from 3,230 broiler and 3,230 layer chickens from September to December 2021 that grew isolates of Escherichia coli, Enterococcus spp. and Salmonella spp. along with their AMR patterns. DESIGN: This was a cross-sectional descriptive study. RESULTS: In broiler birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 36%, 39% and 63% of swabs. In layer birds, Enterococcus spp., Salmonella spp. and E. coli were identified in respectively 31%, 48% and 60% of swabs. For both bird types, there was variation in bacterial prevalence between the regions. For all three bacterial isolates, the lowest antimicrobial resistance was found with amikacin. For the other nine antibiotics tested, >50% of bacterial isolates showed resistance; between 60% and 90% of isolates showed resistance to ciprofloxacin and trimethoprim-sulfamethoxazole. Multidrug resistance ranged from 45% to 46% for Salmonella spp., 37-44% for E. coli and 13-17% for Enterococcus spp. CONCLUSION: This study shows that a large proportion of poultry in Nepal are infected with potentially pathogenic bacteria, and these are frequently resistant to commonly used antibiotics. Nepal urgently needs to implement corrective measures.

CONTEXTE: Vingt fermes avicoles dans cinq provinces du Népal ont été sélectionnées pour étudier les pathogènes bactériens et leurs profils de résistance aux antimicrobiens (AMR). OBJECTIF: Documenter la proportion d'écouvillons cloacaux prélevés chez 3 230 poulets de chair et 3 230 poules pondeuses de septembre à décembre 2021 qui ont produit des isolats d'Escherichia coli, d'Enterococcus spp. et de Salmonella spp. ainsi que leurs profils d'AMR. MÉTHODE: Il s'agissait d'une étude descriptive transversale. RÉSULTATS: Chez les poulets de chair, Enterococcus spp., Salmonella spp. et E. coli ont été identifiés dans respectivement 36%, 39% et 63% des écouvillons. Chez les pondeuses, Enterococcus spp., Salmonella spp. et E. coli ont été identifiés dans respectivement 31%, 48% et 60% des écouvillons. Pour les deux types d'oiseaux, la prévalence bactérienne varie selon les régions. Pour les trois isolats bactériens, la résistance la plus faible a été observée avec l'amikacine. Pour les neuf autres antibiotiques testés, >50% des isolats bactériens présentaient une résistance ; entre 60% et 90% des isolats présentaient une résistance à la ciprofloxacine et au triméthoprime-sulfaméthoxazole. La multirésistance variait de 45 à 46% pour Salmonella spp, 37 à 44% pour E. coli et 13 à 17% pour Enterococcus spp. CONCLUSION: Cette étude montre qu'une grande proportion de volailles au Népal est infectée par des bactéries potentiellement pathogènes, et que celles-ci sont fréquemment résistantes aux antibiotiques couramment utilisés. Le Népal doit de toute urgence mettre en œuvre des mesures correctives.

Clinical standards for the diagnosis, treatment and prevention of TB infection.

BACKGROUND: Tuberculosis (TB) preventive therapy (TPT) decreases the risk of developing TB disease and its associated morbidity and mortality. The aim of these clinical standards is to guide the assessment, management of TB infection (TBI) and implementation of TPT.METHODS: A panel of global experts in the field of TB care was identified; 41 participated in a Delphi process. A 5-point Likert scale was used to score the initial standards. After rounds of revision, the document was approved with 100% agreement.RESULTS: Eight clinical standards were defined: Standard 1, all individuals belonging to at-risk groups for TB should undergo testing for TBI; Standard 2, all individual candidates for TPT (including caregivers of children) should undergo a counselling/health education session; Standard 3, testing for TBI: timing and test of choice should be optimised; Standard 4, TB disease should be excluded prior to initiation of TPT; Standard 5, all candidates for TPT should undergo a set of baseline examinations; Standard 6, all individuals initiating TPT should receive one of the recommended regimens; Standard 7, all individuals who have started TPT should be monitored; Standard 8, a TBI screening and testing register should be kept to inform the cascade of care.CONCLUSION: This is the first consensus-based set of Clinical Standards for TBI. This document guides clinicians, programme managers and public health officers in planning and implementing adequate measures to assess and manage TBI.

Viewpoint: Why do we need a point-of-care CD4 test for low-income countries?

In this paper, we discuss the reasons why we urgently need a point-of-care (POC) CD4 test, elaborate the problems we have experienced with the current technology which hampers CD4-count coverage and highlight the ideal characteristics of a universal CD4 POC test. It is high-time that CD4 technology is simplified and adapted for wider use in low-income countries to change the current paradigm of restricted access once and for all.

Antiretroviral treatment uptake and attrition among HIV-positive patients with tuberculosis in Kibera, Kenya.

Using data of human immunodeficiency virus-positive patients with tuberculosis from three primary care clinics in Kibera slums, Nairobi, Kenya, we report on the proportion that started antiretroviral treatment (ART) and attrition (deaths, lost to follow-up and stopped treatment) before and while on ART. Of 427 ART eligible patients, enrolled between January 2004 and December 2008, 70% started ART, 19% were lost to attrition and 11% had not initiated ART. Of those who started ART, 14% were lost to attrition, making a cumulative pre-ART and ART attrition of 33%. ART uptake among patients with TB was relatively good, but programme attrition was high and needs urgent addressing.

Demographic characteristics and opportunistic diseases associated with attrition during preparation for antiretroviral therapy in primary health centres in Kibera, Kenya.

Using routine data from HIV-positive adult patients eligible for antiretroviral therapy (ART), we report on routinely collected demographic characteristics and opportunistic diseases associated with pre-ART attrition (deaths and loss to follow-up). Among 2471 ART eligible patients, enrolled between January 2005 and November 2008, 446 (18%) were lost to attrition pre-ART. Adjusted risk factors significantly associated with pre-ART attrition included age <35 years (Odds Ratio, OR 1.4, 95% Confidence Interval, CI 1.1-1.8), severe malnutrition (OR 1.5, 95% CI 1.1-2.0), active pulmonary tuberculosis (OR 1.6, 95% CI 1.1-2.4), severe bacterial infections including severe bacterial pneumonia (OR 1.9, 95% CI 1.2-2.8) and prolonged unexplained fever (>1 month), (OR 2.6, 95% CI 1.3-5.2). This study highlights a number of clinical markers associated with pre-ART attrition that could serve as 'pointers' or screening tools to identify patients who merit fast-tracking onto ART and/or closer clinical attention and follow-up.

Research needs for an improved primary care response to chronic non-communicable diseases in Africa.

With non-communicable diseases (NCDs) projected to become leading causes of morbidity and mortality in developing countries, research is needed to improve the primary care response, especially in sub-Saharan Africa. This region has a particularly high double burden of communicable diseases and NCDs and the least resources for an effective response. There is a lack of good quality epidemiological data from diverse settings on chronic NCD burden in sub-Saharan Africa, and the approach to primary care of people with chronic NCDs is currently often unstructured. The main primary care research needs are therefore firstly, epidemiological research to document the burden of chronic NCDs, and secondly, health system research to deliver the structured, programmatic, public health approach that has been proposed for the primary care of people with chronic NCDs. Documentation of the burden and trends of chronic NCDs and associated risk factors in different settings and different population groups is needed to enable health system planning for an improved primary care response. Key research issues in implementing the programmatic framework for an improved primary care response are how to (i) integrate screening and prevention within health delivery; (ii) validate the use of standard diagnostic protocols for NCD case-finding among patients presenting to the local health facilities; (iii) improve the procurement and provision of standardised treatment and (iv) develop and implement a data collection system for standardised monitoring and evaluation of patient outcomes. Important research considerations include the following: selection of research sites and the particular NCDs targeted; research methodology; local research capacity; research collaborations; ethical issues; translating research findings into policy and practice and funding. Meeting the research needs for an improved health system response is crucial to deliver effective, affordable and equitable care for the millions of people with chronic NCDs in developing countries in Africa.

The published research paper: is it an important indicator of successful operational research at programme level?

Is a published research paper an important indicator of successful operational research at programme level in low-income countries? In academia, publishing in peer-reviewed scientific journals is highly encouraged and strongly pursued for academic recognition and career progression. In contrast, for those who engage in operational research at programme level, there is often no necessity or reward for publishing the results of research studies; it may even be criticized as being an unnecessary detraction from programme-related work. We present arguments to support publishing operational research from low-income countries; we highlight some of the main reasons for failure of publication at programme level and suggest ways forward.

Characteristics, immunological response & treatment outcomes of HIV-2 compared with HIV-1 & dual infections (HIV 1/2) in Mumbai.

BACKGROUND AND OBJECTIVES: Information available on HIV-2 and dual infection (HIV-1/2) is limited. This study was carried out among HIV positive individuals in an urban referral clinic in Khar, Mumbai, India, to report on relative proportions of HIV-1, HIV-2 and HIV-1/2 and baseline characteristics, response to and outcomes on antiretroviral treatment (ART). METHODS: Retrospective analysis of programme data (May 2006-May 2009) at Khar HIV/AIDS clinic at Mumbai, India was done. Three test algorithm was used to diagnose HIV-1 and -2 infection. Standard ART was given to infected individuals. Information was collected on standardized forms. RESULTS: A total of 524 individuals (male=51%; median age=37 yr) were included in the analysis over a 3 year period (2006-2009) - 489 (93%) with HIV-1, 28 (6%) with HIV-2 and 7(1%) with dual HIV-1/2 infection. HIV-2 individuals were significantly older than HIV-1 individuals (P<0.001). A significantly higher proportion of HIV-2 patients and those with dual infections had CD4 counts <200 cells/µl compared to HIV-1. HIV-2 individuals were more likely to present in WHO Clinical Stage 4. Of the 443 patients who were started on ART, 358 (81%) were still alive and on ART, 38 (8.5%) died and 3 were transferred out. CD4 count recovery at 6 and 12 months was satisfactory for HIV-1 and HIV-2 patients on protease inhibitor based regimens while this was significantly lower in HIV-2 individuals receiving 3 nucleoside reverse transcriptase inhibitors. INTERPRETATION AND CONCLUSIONS: In an urban HIV clinic in Mumbai, India, HIV-2 and dual infections are not uncommon. Adaptation of the current national diagnostic and management protocols to include discriminatory testing for HIV types and providing access to appropriate and effective ART regimens will prevent the development of viral resistance and preserve future therapeutic options.

A report on the Zimbabwe Antiretroviral Therapy (ART) programme progress towards achieving MGD6 target 6B: achievement and challenges.

Zimbabwe's target to achieve Universal Access to treatment for HIV and AIDS, was severely affected by a decade long economic recession that threatened to reverse all the country's social and economic indicators. Despite these challenges, by September 2010, 282,916 adults and children (47.7% of those in need of treatment) were on treatment at 509 sites countrywide since national scale up started. ART services are predominantly offered through the public sector, with the private sector being an untapped potential resource for ART services for the future. Challenges of skilled and adequately trained human resources have hindered progress towards service availability. Providing access to children in particular has been constrained by lack of clinical mentorship for health workers, weak systems for support supervision, and inadequate HIV diagnostic services especially for children under 18 months and challenges with follow up of the HIV-exposed infants. Though the country has not met its target of Universal Access by 2010, significant progress has been made with over a 30-fold increase in service availability.
