Abstract:

Background: Kenyatta National Hospital (KNH) is a referral center serving patients from
Kenya and beyond. There are several departments among them orthopedics which houses
many patients with wounds, some of which are infected thereby increasing morbidity and
mortality. This research focused on etiology and risk factors of bacterial wound infections in
the orthopedics wards.
Objective: To assess the factors that contribute to wound infections. The specific factors
assessed were prevalence of aerobic bacteria. use of antibiotics and clinical practices among
the nurses when dressing wounds.
:VIethods: A descriptive research design was used and target populations were nurses and
hospitalized patients in the department of orthopedics at KNH. Sixteen nurses and one
hundred and fifteen patients were selected using simple random sampling and convenience
sampling techniques respectively. Data was collected using a questionnaire and specimens
taken from wounds analyzed in microbiology laboratories ofUON and KNH.
Results: The prevalence of bacteria isolated was; Pseudomonas spp. (42.6%). Proteus spp.
(33.9%). Staphylococcus aureus (33%). Klebsiella spp. (7.9%), Streptococcus faecalis
(6.1%), Enterbacter spp. (2.6%), Alcaligenes spp. (1.7%), Citrobacter freundii (0.9%),
Serratia spp. (0.9%), and Acinetobacter baumanii (0.9%).
The sensitivity patterns were as follows: Pseudomonas spp.; Pipril/Tozabactam (89.9%),
Meropenem (75.5%). Gentamycin (55.1%), Amikacin (73.5%), Ceftazidime (82.6%),
Ceftriaxone (30.6%), TicatcilliniClavulonic acid (65.3%) and Piperacillin (83.7%).
Proteus spp.: Ceftazidime (89.7%), Ceftriaxone (79.5%), Ciprofloxacin (87.2%), Augmentin
(76.9°/0). Cefuroxime (61.5%). Piperaciliin H8.7%)"Gentamycin (-1-6.2%)
