Drug sensitivity patterns of bacterial isolates from septic post-operative wounds in a regional referral hospital in Uganda

Background: Wound infections have been a problem in the field of surgery for a long time.Advances in control of infections have not completely eradicated this problem because of development of drug resistance.Antimicrobial resistance can increase complications and costs associated with procedures and treatment. Objective: A study was carried out on drug sensitivity patterns of bacterial isolates from septic postoperative wounds in Jinja hospital, Uganda.This study was designed to determine the distribution of bacterial pathogens isolated from septic post-operative wounds and their antimicrobial susceptibility patterns. Method: Specimens of pus swabs were collected aseptically and analysed in the laboratory. Colony characteristics and Grams technique were used to differentiate the organisms. Biochemical tests were done to confirm the species of the organisms. Sensitivity testing was done on the isolates using the disk diffusion method. Results: Pathogenic bacteria were recovered from 58.5% of the specimens.The isolates were: S.aureus (45.1%), Coliforms (16.9%), Proteus mirabilis (11.3%), P.aeruginosa (9.9%), Klebsiella pneumoniae (7.0%) and Enterobacter spp (2.82%). Most of the organisms were sensitive to gentamicin, ciprofloxacin and ceftazidime.There was resistance to ampicillin, amoxycillin and chloramphenicol. Staphylococcus aureus was generally sensitive to gentamicin (87.5%), ciprofloxacin (68.7%) and methicillin (75%), but resistant to erythromycin (56.2%) and ampicillin (97%). Most of the gram-negative bacteria isolated (Coliforms, P.aeruginosa , E.coli , Proteus mirabilis , and Klebsiella pneumoniae ) were sensitive to Ciprofloxacin, Gentamicin and Ceftazidime but resistant to Ampicillin,Amoxycillin and Chloramphenicol. Methicillin-resistant Staphylococcus aureus (MRSA) strains formed 25% of this species. Pseudomonas aeruginosa was sensitive to gentamicin (87.5%) and ceftazidime (85.7%) but showed resistance to ciprofloxacin (57.2%). Some organisms e.g. S.aureus, Pseudomonas aeruginosa and Proteus mirabilis exhibited multi-drug resistance to the antibiotics tested. Conclusion: Since a high proportion of samples had positive cultures, infection control is recommended as a strategy to minimise spread of resistant organisms. It is recommended that gentamicin, ciprofloxacin and ceftazidime be used in preference to ampicillin and amoxycillin for treatment of septic wounds.There is need to develop national surveillance of antibiotic- resistant organisms.

The conduct of maternal and perinatal death reviews in Oyam District, Uganda: a descriptive cross-sectional study

BACKGROUND: Uganda like many developing countries still experiences high levels of maternal and perinatal deaths despite a decade of maternal and perinatal death review (MPDR) program. Oyam district has been implementing MPDR since 2008 with varying successes among the health facilities. This paper presents the factors that influence the conduct of maternal and perinatal death reviews in Oyam District, Uganda. METHODS: This was a cross-sectional study where both qualitative and quantitative data were collected. Semi-structured interviews were administered to 66 health workers and ten key informants (KIs) to assess the factors influencing the conduct of MPDR. Univariate and Bivariate analysis of quantitative data was done using SPSS version 17.0. A Pearson Chi-Square test was done to determine factors associated with conduct of MPDR. Factors with a p-value < 0.05 were considered statistically significant. Qualitative data was analyzed using content analysis. RESULTS: Only 34.8 % of the health workers had ever participated in MPDR. The factors that influenced conduct of MPDR were existence of MPDR committees (p < 0.001), attendance of review meetings (p < 0.001) and knowledge of objectives of MPDR (p < 0.001), implementation of MPDR recommendations (p < 0.001), observed improvement in maternal and newborn care (p < 0.001) and provision of feedback (p < 0.001). Hindrance to conduct of MPDR was obtained from KIs: the health workers were not made aware of the MPDR process, committee formation and training of MPDR committee members was not effectively done, inadequate support supervision, and lack of financial motivation of MPDR committee members. Challenges to MPDR included: heavy workload to health workers, high number of perinatal deaths, and non-implementation of recommendations. CONCLUSION: The proportion of maternal and perinatal death reviews conducted in Oyam was low. This was due to poor initiation of the review process and a lack of support supervision. The district and Ministry of Health needs to put more emphasis on monitoring the conduct of maternal and perinatal death reviews by: forming and training MPDR committees and ensuring they are financially supported, providing overall coordination, and ensuring effective support supervision.

Molecular Characterization of Staphylococcus aureus from Patients with Surgical Site Infections at Mulago Hospital in Kampala, Uganda

BACKGROUND: The prevalence of Methicillin resistant Staphylococcus aureus (MRSA) is progressively increasing globally with significant regional variation. Understanding the Staphylococcus aureus lineages is crucial in controlling nosocomial infections. Recent studies on S. aureus in Uganda have revealed an escalating burden of MRSA. However, the S. aureus genotypes circulating among patients are not known. Here, we report S. aureus lineages circulating in patients with surgical site infections (SSI) at Mulago National hospital, Kampala, Uganda. METHODS: A cross-sectional study involving 314 patients with SSI at Mulago National Hospital was conducted from September 2011 to April 2012. Pus swabs from the patients’ SSI were processed using standard microbiological procedures. Methicillin sensitive Staphylococcus aureus (MSSA) and MRSA were identified using phenotypic tests and confirmed by PCR-detection of the nuc and mecA genes, respectively. SCCmec genotypes were determined among MRSA isolates using multiplex PCR. Furthermore, to determine lineages, spa sequence based-genotyping was performed on all S. aureus isolates. RESULTS: Of the 314 patients with SSI, S. aureus accounted for 20.4% (64/314), of which 37.5% (24/64) were MRSA. The predominant SCCmec types were type V (33.3%, 8/24) and type I (16.7%, 4/24). The predominant spa lineages were t645 (17.2%, 11/64) and t4353 (15.6%, 10/64), and these were found to be clonally circulating in all the surgical wards. On the other hand, lineages t064, t355, and t4609 were confined to the obstetrics and gynecology wards. A new spa type (t10277) was identified from MSSA isolate. On multivariate logistic regression analysis, cancer and inducible clindamycin resistance remained as independent predictors of MRSA-SSI. CONCLUSION: SCCmec types I and V are the most prevalent MRSA mecA types from the patients’ SSI. The predominant spa lineages (t645 and t4353) are clonally circulating in all the surgical wards, calling for strengthening of infection control practices at Mulago National Hospital
