Community referral for presumptive TB in Nigeria: a comparison of four models of active case finding.

BACKGROUND: Engagement of communities and civil society organizations is a critical part of the Post-2015 End TB Strategy. Since 2007, many models of community referral have been implemented to boost TB case detection in Nigeria. Yet clear insights into the comparative TB yield from particular approaches have been limited. METHODS: We compared four models of active case finding in three Nigerian states. Data on presumptive TB case referral by community workers (CWs), TB diagnoses among referred clients, active case finding model characteristics, and CWs compensation details for 2012 were obtained from implementers and CWs via interviews and log book review. Self-reported performance data were triangulated against routine surveillance data to assess concordance. Analysis focused on assessing the predictors of presumptive TB referral. RESULTS: CWs referred 4-22% of presumptive TB clients tested, and 4-24% of the total TB cases detected. The annual median referral per CW ranged widely among the models from 1 to 48 clients, with an overall average of 13.4 referrals per CW. The highest median referrals (48 per CW/yr) and mean TB diagnoses (7.1/yr) per CW (H =70.850, p < 0.001) was obtained by the model with training supervision, and $80/quarterly payments (Comprehensive Quotas-Oriented model). The model with irregularly supervised, trained, and compensated CWs contributed the least to TB case detection with a median of 13 referrals per CW/yr and mean of 0.53 TB diagnoses per CW/yr. Hours spent weekly on presumptive TB referral made the strongest unique contribution (Beta = 0.514, p < 0.001) to explaining presumptive TB referral after controlling for other variables. CONCLUSION: All community based TB case-finding projects studied referred a relative low number of symptomatic individuals. The study shows that incentivized referral, appropriate selection of CWs, supportive supervision, leveraged treatment support roles, and a responsive TB program to receive clients for testing were the key drivers of community TB case finding.

Pregnancy-related acute kidney injury: Etiologies and short-term outcomes in a tertiary hospital in Southwest Nigeria.

Although the incidence of pregnancy-related acute kidney injury (PRAKI) is declining in developing countries, it still remains a major cause of maternal and fetal morbidity and mortality. The aim of this study was to determine the etiologies, short-term outcomes, and their predictors in patients with PRAKI managed in a tertiary health facility in Southwest Nigeria over a four-year period. This was a four-year retrospective review of clinical records of patients managed for PRAKI in University of Medical Sciences Teaching Hospital, Ondo State, Nigeria. Thirty-two women with a mean age of 31.09 ± 7.50 years had PRAKI during the period reviewed. Twenty-four (75%) patients were multiparous and PRAKI was most common in the postpartum period (56.3%). Twenty-three patients (71.9%) were in RIFLE Stage 3, 24 (75%) received blood transfusion, 5 (15.6%) required intensive care unit (ICU) care, 24 (75%) needed dialysis while 19 (59.4%) had hemodialysis. The common causes of PRAKI were obstetric hemorrhage in 16 (50%), sepsis in seven (21.9%), and eclampsia in six (18.8%). Maternal and fetal mortality were 34.4% and 50% respectively. Seventeen (53.1%) had full renal recovery and only one (3.1%) became dialysis dependent. Significant factors that were associated with maternal mortality were admission to ICU (P = 0.01), hypotension (P = 0.02), and impaired consciousness (P <0.001) PRAKI is still relatively common and significantly contributes to maternal and perinatal mortality in Nigeria. Obstetric hemorrhage which is the most common cause of PRAKI is preventable and treatable. There is a need for physicians to effectively prevent and manage obstetric hemorrhage.
