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

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..

Trends in birth attendants in Sudan using three consecutive household surveys (from 2006 to 2014)

Introduction

Improving maternal health and survival remains a public health priority for Sudan. Significant investments were made to expand access to maternal health services, such as through the training and deployment of providers with varying skills and competencies to work across the country. This study investigates trends in the coverage of different birth attendants and their relationship with the maternal mortality ratio (MMR).

Methods

Trend analyses were conducted using data from the 2006, 2010, and 2014 Sudan Household surveys. Three categories of birth attendants were identified: (1) skilled birth attendants (SBA) such as doctors, nurse-midwives, and health visitors, (2) locally certified midwives, and (3) traditional birth attendants (TBA). Multivariable logistic regression models were used to examine trends in SBAs (vs. locally certified midwives and TBAs), locally certified midwives (vs SBAs and TBAs), and SBAs and locally certified midwives by place of birth (health facility and home). The analyses were adjusted for potential confounders. An ecological analysis was conducted to assess the relationship between birth attendants by place of birth and MMR at the state level.

Results

Births by 15,848 women were analysed. Locally certified midwives attended most births in each survey year, with their contribution increasing from 36.3% in 2006 to 55.5% in 2014. The contributions of SBAs and TBAs decreased over the same period. In 2014 compared with 2006, births were more likely to be attended by a locally certified midwife (aOR: 2.19; 95%CI: 1.82-2.63) but less likely to be attended by a SBA (aOR: 0.46; 95%CI: 0.37-0.56). The decrease in SBA was more substantial for births taking place at home (aOR: 0.17; 95%CI: 0.12-0.23) than for health facility births (aOR: 0.45; 95%CI: 0.31-0.65). In the ecological analysis 2014-2016, the proportion of births attended by SBA in health facilities correlated negatively with MMR at state level (rho -0.55; p: 0.02).

Conclusion

This analysis suggests that although an improved coverage of maternal health with locally certified midwives has been observed, it has not provided the skill level reached by SBA. SBAs working in facility settings were a key correlating factor to reduced maternal mortality. Urgent action is needed to improve access to SBAs in health facilities, thereby accelerating progress in reducing maternal mortality.

Annual consumption of parenteral antibiotics in a tertiary hospital of Nepal, 2017-2019: a cross-sectional study

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.

Surgical antibiotic prophylaxis administration practices

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.

Building the capacity of public health programmes to become data rich, information rich and action rich

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.

Factors related to environmental barriers experienced by persons with and without disabilities in diverse African settings

This paper explores differences in experienced environmental barriers between individuals with and without disabilities and the impact of additional factors on experienced environmental barriers. Data was collected in 2011–2012 by means of a two-stage cluster sampling and comprised 400–500 households in different sites in South Africa, Sudan Malawi and Namibia. Data were collected through self-report survey questionnaires. In addition to descriptive statistics and simple statistical tests a structural equation model was developed and tested. The combined file comprised 9,307 participants. The Craig Hospital Inventory of Environmental Factors was used to assess the level of environmental barriers. Transportation, the natural environment and access to health care services created the biggest barriers. An exploratory factor analysis yielded support for a one component solution for environmental barriers. A scale was constructed by adding the items together and dividing by number of items, yielding a range from one to five with five representing the highest level of environmental barriers and one the lowest. An overall mean value of 1.51 was found. Persons with disabilities scored 1.66 and persons without disabilities 1.36 (F = 466.89, p < .001). Bivariate regression analyses revealed environmental barriers to be higher among rural respondents, increasing with age and severity of disability, and lower for those with a higher level of education and with better physical and mental health. Gender had an impact only among persons without disabilities, where women report more barriers than men. Structural equation model analysis showed that socioeconomic status was significantly and negatively associated with environmental barriers. Activity limitation is significantly associated with environmental barriers when controlling for a number of other individual characteristics. Reducing barriers for the general population would go some way to reduce the impact of these for persons with activity limitations, but additional and specific adaptations will be required to ensure an inclusive society.

Effect of increased ART-CPT uptake on tuberculosis outcomes and associated factors, Burundi, 2009-2013

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.

Building operational research capacity in the Pacific

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.

The Structured Operational Research and Training Initiative for public health programmes

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.

Open access for operational research publications from low- and middle-income countries: who pays?

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.

Sex, drugs and prisons: HIV prevention strategies for over 190 000 clients in Ukraine

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.

Are sputum samples of retreatment tuberculosis reaching the reference laboratories? A 9-year audit in Tanzania

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.

Poor treatment outcomes among multidrug-resistant tuberculosis patients in Gomel Region, Republic of Belarus

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.

Non-adherence to standard treatment guidelines in a rural paediatric hospital in Sierra Leone

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.

Prevalence of anaemia, syphilis and hepatitis B in pregnant women in Nausori, Fiji

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.

Performance of decentralised facilities in tuberculosis case notification and treatment success in Armenia

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.

Treatment outcomes among drug-susceptible tuberculosis patients in Latvia, 2006-2010

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.

Human resources for primary health care in sub-Saharan Africa: progress or stagnation?

BACKGROUND

The World Health Organization defines a "critical shortage" of health workers as being fewer than 2.28 health workers per 1000 population and failing to attain 80% coverage for deliveries by skilled birth attendants. We aimed to quantify the number of health workers in five African countries and the proportion of these currently working in primary health care facilities, to compare this to estimates of numbers needed and to assess how the situation has changed in recent years.

METHODS

This study is a review of published and unpublished "grey" literature on human resources for health in five disparate countries: Mali, Sudan, Uganda, Botswana and South Africa.

RESULTS

Health worker density has increased steadily since 2000 in South Africa and Botswana which already meet WHO targets but has not significantly increased since 2004 in Sudan, Mali and Uganda which have a critical shortage of health workers. In all five countries, a minority of doctors, nurses and midwives are working in primary health care, and shortages of qualified staff are greatest in rural areas. In Uganda, shortages are greater in primary health care settings than at higher levels. In Mali, few community health centres have a midwife or a doctor. Even South Africa has a shortage of doctors in primary health care in poorer districts. Although most countries recognize village health workers, traditional healers and traditional birth attendants, there are insufficient data on their numbers.

CONCLUSION

There is an "inverse primary health care law" in the countries studied: staffing is inversely related to poverty and level of need, and health worker density is not increasing in the lowest income countries. Unless there is money to recruit and retain staff in these areas, training programmes will not improve health worker density because the trained staff will simply leave to work elsewhere. Information systems need to be improved in a way that informs policy on the health workforce. It may be possible to use existing resources more cost-effectively by involving skilled staff to supervise and support lower level health care workers who currently provide the front line of primary health care in most of Africa.

Perceived Barriers for Accessing Health Services among Individuals with Disability in Four African Countries

There is an increasing awareness among researchers and others that marginalized and vulnerable groups face problems in accessing health care. Access problems in particular in low-income countries may jeopardize the targets set by the United Nations through the Millennium Development Goals. Thus, identifying barriers for individuals with disability in accessing health services is a research priority. The current study aimed at identifying the magnitude of specific barriers, and to estimate the impact of disability on barriers for accessing health care in general. A population based household survey was carried out in Sudan, Namibia, Malawi, and South Africa, including a total of 9307 individuals. The sampling strategy was a two-stage cluster sampling within selected geographical areas in each country. A listing procedure to identify households with disabled members using the Washington Group six screening question was followed by administering household questionnaires in households with and without disabled members, and questionnaires for individuals with and without disability. The study shows that lack of transport, availability of services, inadequate drugs or equipment, and costs, are the four major barriers for access. The study also showed substantial variation in perceived barriers, reflecting largely socio-economic differences between the participating countries. Urbanity, socio-economic status, and severity of activity limitations are important predictors for barriers, while there is no gender difference. It is suggested that education reduces barriers to health services only to the extent that it reduces poverty. Persons with disability face additional and particular barriers to health services. Addressing these barriers requires an approach to health that stresses equity over equality.

Risk factors associated with loss to follow-up among multidrug-resistant tuberculosis patients in Georgia

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?

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.

Do non-monetary incentives for pregnant women increase antenatal attendance among Ethiopian pastoralists?

In a pastoralist setting in Ethiopia, we assessed changes in attendance between the first and subsequent antenatal care (ANC) visits following the implementation of non-monetary incentives in a primary health care centre over a 3-year period from October 2009 to September 2012. Incentives included the provision of a bar of soap, a bucket, a mosquito net, sugar, cooking oil, a jerrycan and a delivery kit. The first ANC visits increased by 48% in the first year to 60% in the second. Subsequent visits did not show a similar pattern due to ruptures in incentive stocks. Incentives appear to increase ANC attendance; however, ruptures in stock should be avoided to sustain the effect.

Childhood immunisation in Bungoma County, Kenya, from 2008 to 2011: need for improved uptake

Uptake of immunisations in children aged 1-2 years in Bungoma County, Kenya, was determined as part of the 6-monthly Health and Demographic Surveillance System surveys. A total of 2699 children were assessed between 2008 and 2011. During this time period, full immunisation declined significantly from 84% to 58%, and measles vaccine declined uptake from 89% to 60% (P < 0.001). Each year there was a significant fall-off for the third doses of the oral polio and pentavalent vaccines (P < 0.001). These findings are of concern, as low immunisation coverage may lead to vaccine-preventable disease outbreaks. Further investigations into the reasons for declining immunisation trends are required.

High loss to follow-up following obstetric fistula repair surgery in rural Burundi: is there a way forward?

SETTING

Gitega Fistula Centre (GFC), a dedicated obstetric fistula repair centre providing comprehensive care at the Gitega District Hospital, rural Burundi.

OBJECTIVES

To describe 1) the proportion who returned for scheduled 3- and 6-month follow-up visits and 2) outcomes (fistula closure rates and continence status) at discharge from hospital and after 3 and 6 months among patients who underwent fistula repair surgery.

DESIGN

Retrospective cohort analysis using programme data from April 2010 to December 2011.

RESULTS

A total of 475 women with obstetric fistula underwent surgical repair. At discharge from hospital, 415 (87%) had a closed fistula, of whom 318 (77%) were continent of urine and/or faeces, while 97 (23%) remained incontinent despite closure. Of the 415 patients with closed fistula, only 244 (59%) were followed up at 3 months and 73 (18%) at 6 months (χ(2) for linear trend 576, P < 0.0001). This indicates progressive loss to follow-up, reaching 82% by 6 months.

CONCLUSION

Women undergoing obstetric fistula repair surgery at GFC achieve good hospital exit outcomes. Thereafter, substantial and progressive loss to follow-up hinder the ability to judge programme success over time. Steps to address this operational problem are discussed.

Nurses graduating in Fiji between 2001 and 2010: sufficient supply for Fiji's health service demands?

SETTING

Fiji's schools of nursing and government health services, 2001-2010.

OBJECTIVES

To report on 1) the number and characteristics of nurses who graduated in Fiji, 2) the proportion of vacant nursing positions in the government health services and 3) attrition among nurses.

DESIGN

Descriptive study involving a retrospective record review of Ministry of Health annual reports and nursing registers.

RESULTS

Over the period 2001-2010, a total of 1500 nurses graduated, with the overall trend being a gradual increase in newly qualified nurses year on year. Available data from 2007 onwards showed relatively low vacancy rates (range 0.4-2%), with a sharp rise to 15% in 2009. Complete data on nurse attrition were available only from 2007 onwards, with rates of attrition ranging from 4% to 10%; the most common reason for attrition was resignation.

CONCLUSION

While it was unable to directly assess whether Fiji's supply of nursing graduates has been meeting the country's health service demands, this study provides a series of baseline data on Fiji's nurse graduate and nursing workforce. In addition, it identifies some of the challenges and gaps that need to be considered to better assess and address nursing staff shortages.

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.

Primary school compliance with school canteen guidelines in Fiji and its association with student obesity

SETTING

Childhood obesity is of growing public health concern in Fiji. The study setting was primary schools in Fiji's Western Division.

OBJECTIVE

1) To assess primary schools' compliance with national school canteen guidelines, 2) to understand reasons for non-compliance, and 3) to assess the relationship between compliance with the guidelines and students' body mass index (BMI).

DESIGN

Cross-sectional analysis of data collected in 2010 by public health dieticians of the Ministry of Health on annual visits to primary schools.

RESULTS

Among 230 schools, 33 (14%) had no canteen data. Of the 197 schools with data, only 31 (16%) were fully compliant with national school canteen guidelines, while the remaining 166 (84%) did not fully comply with the guidelines. This was irrespective of school location or whether the canteen was school or commercially operated. In a random sample (n = 44 schools), overweight and obesity were more common among children in non-compliant schools than in fully compliant schools (40% vs. 32%, P < 0.001).

CONCLUSION

Most primary schools in Fiji's Western Division did not comply with school canteen guidelines, which is worrying given the increasing rates of overweight children. Given the association between non-compliance and student overweight/obesity, further action is needed to ensure that these guidelines are implemented.

Intrauterine growth standards in a developing country: a study of singleton livebirths at 28-42 weeks' gestation

This study aimed to develop fetal growth charts for the population of Greater Beirut, Lebanon, and compare them with previously established references. A survey of consecutive singleton livebirths admitted to normal nurseries and neonatal intensive care units of major hospitals, through the database project of the National Collaborative Perinatal Neonatal Network was used as a design. The study was conducted in nine major healthcare institutions serving the population of Beirut and its suburbs. A total of 24 767 singleton livebirths delivered between 28 and 42 weeks' gestation, with known data on gender, gestational age and anthropometric characteristics were recorded between 1 April 1999 and 31 March 2002. Growth charts were developed by plotting birthweight, length and head circumference percentiles against gestational age for male and female infants separately. Overall, 1348 (5.4%) pregnancies were delivered before 37 weeks' gestation and 1227 (4.9%) were low birthweight. Male infants were delivered slightly earlier than their female counterparts and the mean birthweight, length and head circumference were consistently higher in males. A total of 2247 (9.1%) infants were small-for-gestational-age, with a male-to-female sex ratio of 1.03. Using previously established growth references that overestimated small-for-gestational-age prevalence resulted in a greater proportion of false positives. The opposite was true for growth references that underestimated small-for-gestational-age prevalence. The current growth charts present useful tools for assessing the general health status of newborn infants delivered at sea level in the urban areas of Lebanon and other East Mediterranean countries.

Effect of consanguinity on birth weight for gestational age in a developing country

Consanguinity, the marriage between relatives, has been associated with adverse child health outcomes because it increases homozygosity of recessive alleles. The objective of this study was to assess the effect of consanguinity on the birth weight of newborns in Greater Beirut, Lebanon. Cross-sectional data were collected on 10,289 consecutive liveborn singleton newborns admitted to eight hospitals belonging to the National Collaborative Perinatal Neonatal Network during the years 2000 and 2001. Birth weight was modeled by use of the fetal growth ratio, defined as the ratio of the observed birth weight to the median birth weight for gestational age. A mixed-effect multiple linear regression model was used to predict the net effect of first- and second-cousin marriage on the birth weight for gestational age, accounting for within-hospital clustering of data. After controlling for medical and sociodemographic covariates, the authors found a statistically significant negative association between consanguinity and birth weight at each gestational age. No significant difference was observed in the decrease in birth weight between the first- and second-cousin marriages. Overall, consanguinity was associated with a decrease in birth weight for gestational age by 1.8% (beta = -0.018, 95% confidence interval: -0.027, -0.008). The largest effects on fetal growth were seen with lower parity and smoking during pregnancy.

Prevalence of hepatitis B in a presumably healthy Lebanese population

OBJECTIVE

Policy makers need data on the prevalence of infection with HBV in order to determine the cost effectiveness of universal immunization against hepatitis B. This study aims at determining the prevalence rate of infection with HBV in a basically healthy group of Lebanese adults.

METHODS

Sera from 2634 presumably healthy Lebanese individuals, mean age 32.1 years, obtained between 1995-1997, were tested for hepatitis B surface antigen (HBsAg). The sample was composed of subjects residing in different areas in Lebanon. Detection of HBsAg was performed utilizing the ELISA technique. The analysis took place in the Clinical Microbiology Laboratory, Department of Pathology and Laboratory Medicine, American University of Beirut Medical Center, Beirut, Lebanon. Chi-square test was used to examine statistical associations.

RESULTS

The prevalence of HBsAg among the samples was 1.6%. Blue-collar employees, smokers and those living in the South of Lebanon were significantly more likely to be infected with hepatitis B virus.

CONCLUSIONS

The data presented indicates that Lebanon has a low prevalence of HBV infection. Costeffective studies are needed to justify universal iminunization against hepatitis B especially in countries where budgets are tight.

Vitamins A and E Status in an Urban Lebanese Population: A Case Study at Dar Al-Fatwa Area, Beirut

Vitamin A and E status are widely studied in various populations because of their association with several diseases. Fasting plasma vitamin A and E status of 857 Lebanese adults residing in Dar Al-Fatwa, Beirut were assessed using high performance liquid chromatography (HPLC). Mean retinol and alpha-tocopherol concentrations were 59.8 ± 29 µg/dL and 1.0 ± 0.5 mg/dL, respectively in which only 0.2% were retinol-deficient, while 0.7% were alpha-tocopherol-deficient. Vitamin A and E correlated positively with plasma concentrations of total cholesterol, low-density lipoprotein (LDL)-cholesterol, and triglycerides. Vitamin E, but not vitamin A, correlated positively with blood pressure and glucose. A good status of vitamins A and E was found among the studied Lebanese sample and the elevation in vitamin A and E levels was associated with unfavorable lipid profile.

Predicting neonatal outcomes: birthweight, body mass index or ponderal index?

AIMS

To compare birthweight (BW), body mass index (BMI) and ponderal index (PI) as predictors of selected short-term (ST) outcomes, namely Neonatal Intensive Care Unit (NICU) admission and prolonged hospitalization (PH), among newborn (NB) infants.

METHODS

Data was collected prospectively on 9,226 infants born during one year at nine tertiary care hospitals in Greater Beirut, Lebanon. The predictive abilities of BW, BMI and PI were compared using the area under the receiver operator characteristic (ROC) curves and sensitivity analysis was performed at the optimal cut-off points for the best anthropometric measurement.

RESULTS

The area under the ROC curve suggested superior discriminative power for BW as compared to BMI or PI, as a predictor of NICU admission (ROC area = 0.73) and PH (ROC area = 0.74). The optimal BW cut-off point was 2750 g (sensitivity: 0.49; specificity: 0.89) and 2950 g (sensitivity: 0.62; specificity: 0.78) for NICU admission and PH, respectively.

CONCLUSION

In our population of NB infants, BW--a crude measure of fetal growth--is a better predictor than either BMI--a measure of adiposity in adults and children--or PI--a measure of thinness at birth--for selected ST outcomes in NB infants.

Household crowding index: a correlate of socioeconomic status and inter-pregnancy spacing in an urban setting

OBJECTIVES

This paper examines the effect of household crowding on inter-pregnancy spacing and its association with socioeconomic indicators, among parous mothers delivered in an urban environment.

DESIGN

Cross sectional survey.

METHODS

Sociodemographic data were obtained on 2466 parous women delivering at eight hospitals in Greater Beirut over a one year period. Statistical methodology comprised Pearson chi(2) test and logistic regression analysis.

MAIN RESULTS

A significant inverse relation was observed between household crowding and socioeconomic status, defined as education and occupation of women and their spouses. Inter-pregnancy spacing increased with higher levels of crowding. Further analysis suggested that this positive association was confounded by maternal demographic characteristics.

CONCLUSIONS

These data have shown that household crowding, a correlate of low parental socioeconomic status, is associated with longer birth intervals. This association, however, seems to be largely explained by maternal age and parity.

Risk factors for term or near-term fetal growth restriction in the absence of maternal complications

The objective of this study was to examine risk factors for term or near-term fetal growth restriction (FGR) in the absence of pregnancy complications. We completed a survey of uncomplicated single live births delivered in Greater Beirut, Lebanon. FGR cases were defined as below the 10th percentile of expected weight at gestational age. Multivariate logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CIs). Main predictors of FGR were female gender (OR, 1.94; 95% CI, 1.46 to 2.59), nulliparity (Or, 1.66; 95% CI, 1.25 ton 2.20), low prepregnancy weight (OR, 2.52; 95% CI, 1.58 to 4.01), short stature (OR, 2.59; 95% CI, 1.57 to 4.28), and low pregnancy weight gain (OR, 1.75; 95% CI, 1.21 to 2.55). Anthropometric characteristics of mothers are important modifiable determinants of fetal size in our developing urban population of uncomplicated births.

Low socioeconomic status and neonatal outcomes in an urban population in a developing country

OBJECTIVE

To investigate the effect of low socioeconomic status indicators, specifically parental educational and occupational characteristics on neonatal health outcomes.

METHODS

Analysis of 3372 newborn infants admitted to five National Collaborative Perinatal Neonatal Network centers (1 February 2000 to 31 January 2002). Outcomes included birth weight, gestational age, admission to the neonatal intensive care unit (NICU) and length of hospital stay. The independent effects of mother's education and occupation as well as father's occupation on health outcomes were assessed by means of stepwise logistic regression analysis.

RESULTS

A total of 271 (8.0%) infants were of low birth weight, 306 (9.1%) were preterm, 410 (12.2%) had NICU admissions and 240 (7.1%) were hospitalized for more than a week. After adjusting for maternal gravidity, age, smoking during pregnancy and pregnancy-related complications, parental socioeconomic characteristics had no significant impact on low birth weight or preterm birth. NICU admission and prolonged hospitalization were significantly correlated with skilled, semi-skilled and unskilled paternal occupations. Illiterate mothers had nearly 3-5 times the risk of NICU admission and prolonged hospitalization.

CONCLUSION

Both father's occupation and mother's education play an important role as determinants of neonatal morbidity characteristics.

Impact of maternal age on preterm delivery and low birthweight: a hospital-based collaborative study of nulliparous Lebanese women in Greater Beirut

OBJECTIVES

To analyze the impact of maternal age at first childbirth on the incidence of preterm delivery and low birthweight among single live births delivered to nulliparous Lebanese women in Greater Beirut.

STUDY DESIGN

Eligible subjects were selected from a consecutive sample of neonatal admissions to nine National Collaborative Perinatal Network participating hospitals over a three-year period (April 1, 1999 to March 31, 2002). Chi-square tests and logistic regression analyses were applied.

RESULTS

Out of 5556 nulliparous mothers, 5.4% had a preterm delivery and 5.2% a low-birthweight infant. In the multivariate analysis, preterm delivery was not significantly affected by old maternal age. Mothers aged 25 years or more remained a high-risk group for low birthweight even after controlling for potentially confounding characteristics.

CONCLUSIONS

Maternal age at first childbirth above 25 years is an independent risk factor for low birthweight, but not for preterm delivery, an outcome influenced mainly by obstetric complications.

The development of a feasible community-specific cardiovascular disease prevention program: triangulation of methods and sources

Triangulation of methods, sources, and investigators can lead to a multidimensional understanding of a particular issue. In this study, the combination of qualitative and quantitative data collection methods, and information from community and coalition members resulted in the development of a tailored community-specific intervention. Three components were triangulated after analyzing each separately. A household survey of community members between the ages of 25 and 64 years was conducted to identify knowledge, attitudes, and behaviors related to cardiovascular disease and to assess risk factor levels. Focus group discussions were conducted with community members to describe facilitators and barriers to healthy lifestyles, as well as possible interventions. Natural group discussions with coalition members analyzed the relevance, feasibility, affordability, acceptability, and sustainability of specific intervention activities. Results from the different components were compared and contrasted. Areas of added information, validation, and contradiction were analyzed and guided the development of intervention activities.

Intestinal parasites among presumably healthy individuals in Lebanon

OBJECTIVE

To determine the prevalence period of intestinal parasites among presumably healthy subjects in Lebanon.

METHODS

One stool specimen from 2634 presumably healthy Lebanese subjects, mean age 32.1 years with a range of 14-71 years, resident of different areas in Lebanon was examined for the presence of parasites. The analysis took place in the Clinical Microbiology Laboratory, Department of Pathology and Laboratory Medicine, American University of Beirut Medical Center, Beirut, Lebanon, over 25-months between 1995-1997.

RESULTS

The prevalence of intestinal parasites was 12.4%. The most common parasites identified were Entamoeba coli (38%), Giardia lamblia (3.1%) and Entamoeba histolytica (2.3%) [corrected].

CONCLUSION

The data presented shows the need to improve hygienic conditions to contain the problem of intestinal infections with parasites in Lebanon.
