Development and implementation of a national programme for the management of severe and very severe pneumonia in children in Malawi
The original publication is available at http://www.plosmedicine.orgThe reduction of child mortality by two-thirds from its 1990 level by 2015—the fourth United Nations Millennium Development Goal—is a major challenge. Pneumonia accounts for much (≥20%) of this mortality in poor countries, but standard case management (SCM) of pneumonia [1] has the potential to reduce overall child mortality. A recent meta-analysis estimated that SCM of pneumonia could reduce overall mortality in neonates, infants under 1 y old, and children aged 0–4 y, respectively, by 27%, 20%, and 24%, and pneumonia-specific mortality by 42%, 36%, and 36% in the same age groups [2].
However, even proven intervention strategies cannot function without an effective ‘‘delivery strategy’’ [3]. For,
example, although the World Health Organization (WHO)/United Nations Children’s Fund has developed an Integrated
Management of Childhood Illness (IMCI) strategy to reduce child mortality, of the 100+ low- and middle-income
countries that introduced IMCI in the 1990s, only 48% had scaled up coverage by the end of 2002. Weak health systems
were the main cause of this failure with the poorest countries doing worst [3].
We describe here the development and scaling-up of a country-wide delivery strategy of SCM for pneumonia in children
in Malawi, a country where more than 200 children per thousand die before they are 5 y old.Funded by the Bill & Melinda Gates Foundation grant ID#: 413 (http://www.gatesfoundation.org/

High Prevalence of Tuberculosis in Previously Treated Patients, Cape Town, South Africa
More than half of smear-positive case-patients had previously undergone treatment
Childhood tuberculosis deskguide and monitoring: An intervention to improve case management in Pakistan
Background: Childhood tuberculosis (TB) has been a neglected area in national TB control programme (NTCP) in high burden countries. The NTP Pakistan adapted the global approaches by developing and piloting its policy guideline on childhood TB in ten districts of the country. We developed an intervention package including a deskguide and a monitoring tool and tested with the ongoing childhood TB care in a district. The objective of our study was to measure effectiveness of intervention package with deskguide and monitoring tool by comparing TB case finding and treatment outcomes among districts in 2008, and performance assessment in intervention district. Method: An intervention study with cohort design within a routine TB control programme comparing case findings and treatment outcomes before and after the intervention, and in districts with and without intervention. We enrolled all children below 15 years registered at all nine public sector hospitals in three districts of Pakistan. The data was collected from hospital TB records. Results: In eight months during 2007 there were 164 childhood TB cases notified, and after intervention in 2008 a total of 194 cases were notified. In intervention district case finding doubled (110% increase) and correct treatment practice significantly increased in eight months. Successful outcomes were significantly higher in intervention district (37,100%) compared to control district A (18, 18%, p < 0.05) and control district B (41, 72%, p < 0.05). Conclusion: Childhood TB deskguide and structured monitoring was associated with improved case management and it augmented NTP policy. More development and implementation in all health services of the district are indicated.publishedVersio
Can follow-up examination of tuberculosis patients be simplified? A study in Chhattisgarh, India
Each follow-up during the course of tuberculosis treatment currently requires two sputum examinations. However, the incremental yield of the second sputum sample during follow-up of different types of tuberculosis patients has never been determined precisely
Treatment delay among tuberculosis patients in Tanzania: Data from the FIDELIS Initiative
<p>Abstract</p> <p>Background</p> <p>Several FIDELIS projects (Fund for Innovative DOTS Expansion through Local Initiatives to Stop TB) in Tanzania were conducted by the National Tuberculosis and Leprosy Programme (NTLP) during the years 2004-2008 to strengthen diagnostic and treatment services. These projects collected information on <it>treatment delay </it>and some of it was available for research purposes. With this database our objective was to assess the duration and determinants of treatment delay among new smear positive pulmonary tuberculosis (TB) patients in FIDELIS projects, and to compare delay according to provider visited prior to diagnosis.</p> <p>Methods</p> <p>Treatment delay among new smear positive TB patients was recorded for each patient at treatment initiation and this information was available and fairly complete in 6 out of 57 districts with FIDELIS projects enrolling patients between 2004 and 2007; other districts had discarded their forms at the time of analysis. It was analysed as a cross sectional study.</p> <p>Results</p> <p>We included 1161 cases, 10% of all patients recruited in the FIDELIS projects in Tanzania. Median delay was 12 weeks. The median duration of cough, weight loss and haemoptysis was 12, 8 and 3 weeks, respectively. Compared to Hai district Handeni had patients with longer delays and Mbozi had patients with shorter delays. Urban and rural patients reported similar delays. Patients aged 15-24 years and patients of 65 years or older had longer delays. Patients reporting contact with traditional healers before diagnosis had a median delay of 15 weeks compared to 12 weeks among those who did not. Patients with dyspnoea and with diarrhoea had longer delays.</p> <p>Conclusion</p> <p>In this patient sample in Tanzania half of the new smear positive pulmonary tuberculosis patients had a treatment delay longer than 12 weeks. Delay was similar in men and women and among urban and rural patients, but longer in the young and older age groups. Patients using traditional healers had a 25% longer median delay.</p
Outcomes of TB Treatment by HIV Status in National Recording Systems in Brazil, 2003–2008
BACKGROUND: Although the Brazilian national reporting system for tuberculosis cases (SINAN) has enormous potential to generate data for policy makers, formal assessments of treatment outcomes and other aspects of TB morbidity and mortality are not produced with enough depth and rigor. In particular, the effect of HIV status on these outcomes has not been fully explored, partly due to incomplete recording in the national database. METHODOLOGY/PRINCIPAL FINDINGS: In a retrospective cohort study, we assessed TB treatment outcomes, including rates of cure, default, mortality, transfer and multidrug resistant TB (MDR-TB) among a purposively chosen sample of 161,481 new cases reported in SINAN between 2003 and 2008. The study population included all new cases reported in the six States with the highest level of completeness of the HIV status field in the system. These cases were mostly male (67%), white (62%), had pulmonary TB (79%) and a suspect chest X ray (83%). Treatment outcomes were best for those HIV negative cases and worst for those known HIV positive patients (cure rate of 85.7% and 55.7% respectively). In multivariate modeling, the risk of having an unfavorable outcome (all outcomes except cure) was 3.09 times higher for those HIV positive compared with those HIV negative (95% CI 3.02-3.16). The risk of death and default also increased with HIV positivity. The group without a known HIV status showed intermediate outcomes between the groups above, suggesting that this group includes some with HIV infection. CONCLUSIONS: HIV status played an important role in TB treatment outcomes in the study period. The outcomes observed in those with known HIV were poor and need to be improved. Those in the group with unknown HIV status indicate the need for wider HIV testing among new TB cases
Indoor solid fuel use and tuberculosis in China: a matched case-control study
<p>Abstract</p> <p>Background</p> <p>China ranks second among the 22 high burden countries for tuberculosis. A modeling exercise showed that reduction of indoor air pollution could help advance tuberculosis control in China. However, the association between indoor air pollution and tuberculosis is not yet well established. A case control study was conducted in Anhui, China to investigate whether use of solid fuel is associated with tuberculosis.</p> <p>Methods</p> <p>Cases were new sputum smear positive tuberculosis patients. Two controls were selected from the neighborhood of each case matched by age and sex using a pre-determined procedure. A questionnaire containing demographic information, smoking habits and use of solid fuel for cooking or heating was used for interview. Solid fuel (coal and biomass) included coal/lignite, charcoal, wood, straw/shrubs/grass, animal dung, and agricultural crop residue. A household that used solid fuel either for cooking and (/or) heating was classified as exposure to combustion of solid fuel (indoor air pollution). Odds ratios and their corresponding 95% confidence limits for categorical variables were determined by Mantel-Haenszel estimate and multivariate conditional logistic regression.</p> <p>Results</p> <p>There were 202 new smear positive tuberculosis cases and 404 neighborhood controls enrolled in this study. The proportion of participants who used solid fuels for cooking was high (73.8% among cases and 72.5% among controls). The majority reported using a griddle stove (85.2% among cases and 86.7% among controls), had smoke removed by a hood or chimney (92.0% among cases and 92.8% among controls), and cooked in a separate room (24.8% among cases and 28.0% among controls) or a separate building (67.8% among cases and 67.6% among controls). Neither using solid fuel for cooking (odds ratio (OR) 1.08, 95% CI 0.62-1.87) nor using solid fuel for heating (OR 1.04, 95% CI 0.54-2.02) was significantly associated with tuberculosis. Determinants significantly associated with tuberculosis were household tuberculosis contact (adjusted OR, 27.23, 95% CI 8.19-90.58) and ever smoking tobacco (adjusted OR 1.64, 96% CI 1.01-2.66).</p> <p>Conclusion</p> <p>In a population where the majority had proper ventilation in cooking places, the association between use of solid fuel for cooking or for heating and tuberculosis was not statistically significant.</p
Are children with tuberculosis in Pakistan managed according to National programme policy guidelines? A study from 3 districts in Punjab
<p>Abstract</p> <p>Background</p> <p>The adherence to policies of National TB Control Programme (NTP) to manage a case of tuberculosis (TB) is a fundamental step to have a successful programme in any country. Childhood TB services faces an unmet challenge of case management due to difficulty with diagnosis and relatively new policies. For control of childhood TB in Pakistan, NTP developed and piloted its guidelines in 2006-2007. The objective of this study was to compare the documented case management practices of pediatricians and its impact on the outcome before and after introducing NTP policy guidelines.</p> <p>Findings</p> <p>An audit of case management practices of a historical cohort study was done in children below 15 years who were put on anti-tuberculosis treatment at all nine public hospitals in three districts in province of Punjab. The study period was two years pre-intervention (2004-05) and two years post-intervention (2006-07) after implementation of new NTP policy guidelines for childhood TB. There were 920 childhood TB cases registered during four years, 189 in pre-intervention period and 731 in post-intervention period. The practices changed significantly in post-intervention period for use of tuberculin skin test (63% of pulmonary cases, 19% of extrapulmonary cases and 67% for site unknown), and for the use of chest x-ray (69% of pulmonary cases, 16% of extrapulmonary cases and 74% for site unknown). Diagnostic scores were recorded for only a minority of cases (18%). The proportion of correct drugs pre- and post-intervention remained same. There were unknown treatment outcomes in 38 out of 141 cases (27%) in pre-intervention and in 483 out of 551 cases (87%) post-intervention, all among the 692 cases without documented treatment supporter.</p> <p>Conclusions</p> <p>The study has shown that pediatricians have started following parts of the national policy guidelines for management of childhood TB. The documented use of diagnostic tools is increased but record keeping of case management practices remained inadequate. This seems to increase case finding substantially but the treatment outcomes were poor mainly due to unknown outcomes. Development and implementation of standardized operational tools and regular monitoring system may improve the services.</p
