Gaps in Infection Prevention and Control in Public Health Facilities of Sierra Leone after the 2014-2015 Ebola Outbreak.

BACKGROUND: High compliance to infection prevention and control (IPC) is vital to prevent health care-associated infections. In the worst 2014-2015 Ebola-affected district in Sierra Leone (Kenema), we assessed (a) average yearly IPC compliance (2016-2018) using a National IPC assessment tool in the district hospital and peripheral health units (PHUs), and (b) gaps in IPC activities, infrastructure and consumables in 2018. METHODS: This was a cross-sectional study using secondary program data. RESULTS: At the district hospital, compliance increased from 69% in 2016 to 73% in 2018 (expected minimal threshold = 70%; desired threshold ≥ 85%). Compliance for screening/isolation facilities and decontamination of medical equipment reached 100% in 2018. The two thematic areas with the lowest compliance were sanitation (44%) and sharps safety (56%). In PHUs (2018), the minimal 70% compliance threshold was not achieved in two (of 10 thematic areas) for Community Health Centers, four for Community Health Posts, and five for Maternal and Child Health Units. The lowest compliance was for screening and isolation facilities (range: 33-53%). CONCLUSION: This baseline assessment is an eye opener of what is working and what is not, and can be used to galvanize political, financial, and material resources to bridge the existing gaps.

Reduced Bacterial Counts from a Sewage Treatment Plant but Increased Counts and Antibiotic Resistance in the Recipient Stream in Accra, Ghana-A Cross-Sectional Study.

Wastewater treatment plants receive sewage containing high concentrations of bacteria and antibiotics. We assessed bacterial counts and their antibiotic resistance patterns in water from (a) influents and effluents of the Legon sewage treatment plant (STP) in Accra, Ghana and (b) upstream, outfall, and downstream in the recipient Onyasia stream. We conducted a cross-sectional study of quality-controlled water testing (January-June 2018). In STP effluents, mean bacterial counts (colony-forming units/100 mL) had reduced E. coli (99.9% reduction; 102,266,667 to 710), A. hydrophila (98.8%; 376,333 to 9603), and P. aeruginosa (99.5%; 5,666,667 to 1550). Antibiotic resistance was significantly reduced for tetracycline, ciprofloxacin, cefuroxime, and ceftazidime and increased for gentamicin, amoxicillin/clavulanate, and imipenem. The highest levels were for amoxicillin/clavulanate (50-97%) and aztreonam (33%). Bacterial counts increased by 98.8% downstream compared to the sewage outfall and were predominated by E. coli, implying intense fecal contamination from other sources. There was a progressive increase in antibiotic resistance from upstream, to outfall, to downstream. The highest resistance was for amoxicillin/clavulanate (80-83%), cefuroxime (47-73%), aztreonam (53%), and ciprofloxacin (40%). The STP is efficient in reducing bacterial counts and thus reducing environmental contamination. The recipient stream is contaminated with antibiotic-resistant bacteria listed as critically important for human use, which needs addressing.
