Healthcare waste management practice and its predictors among health workers in private health facilities in Ilu Aba Bor Zone, Oromia region, South West Ethiopia: a community-based cross-sectional study.

OBJECTIVES: A lack of safe healthcare waste management (HCWM) practice poses a risk to healthcare staff, patients and communities. In low-income countries like Ethiopia, studies on the level of safe HCWM practices in private healthcare facilities are limited. This study was designed to assess the level of good HCWM practice and associated factors among health workers in private health facilities. METHODS: An institution-based cross-sectional study was conducted in the Ilu Aba Bor zone, South West Ethiopia. A random sample of 282 health workers from 143 private health facilities was included in the study. Data were collected using a pretested structured questionnaire that included sociodemographic characteristics, healthcare factors, knowledge assessment and an observation checklist adapted from WHO guidelines. The collected data were entered into EpiData V.3.1 and analysed with SPSS V.25.0. Multivariable logistic regression analysis was used to identify factors associated with HCWM practice. Variables with a p value of <0.05 at 95% CI were declared significant. RESULTS: More than half (58.7%) of private-sector health workers had good HCWM practice. The presence of the HCWM committee (adjusted OR (AOR)=9.6, 95% CI 4.5 to 20.6), designated healthcare waste storage site (AOR=3.0, 95% CI 1.5 to 6.5), reading the HCWM manual (AOR=4.4, 95% CI 2.2 to 9.0) and having good knowledge of HCWM (AOR=2.6, 95% CI 1.06 to 6.15) were factors associated with good HCWM practice. CONCLUSION: About three out of five health workers in private healthcare facilities were practising good HCWM. The presence of an HCWM committee, waste management utilities, reading HCWM guidelines and knowledge of health workers were the identified factors. Health workers should read guidelines to improve their knowledge, and the presence of committees and waste management utilities in private clinics should be followed to ensure compliance with safe HCWM practice.

Microbial Indoor Air Quality and Associated Factors in Jimma Town Prison Administration, Southwestern Ethiopia.

Indoor air quality determines the well-being of occupants. It has been linked to sick building syndrome and building-related diseases which lead to many socio-economic problems including reduced productivity and impaired learning. Indoor air quality problem is more serious for prisoners, due to their confinement and exposure condition. However, it has not been studied in our study setting. Thus, this study aimed to determine the indoor air microbial quality and associated factors in Jimma town prison administration, Southwestern Ethiopia. A cross-sectional study design was employed in August 2021. Data on the general condition of the prison rooms and occupancy were collected by trained data collectors using an observational checklist. The microbial sample was collected using a sterilized Petri dish. A total of 19 triplicate air samples were collected using Mannitol salt agar and Sabouroad dextrose agar media for the growth of S. aureus and fungi respectively. Data were analyzed using SPSS version 23 and presented using tables and a graph. The effect of predictor variables on the microbial load was also analyzed by using linear regression. The finding of this study revealed that the microbial load of indoor air at Jimma town prison administration ranged from 891 to 15 439 and 315 to 3067 CFU/m³ for S. aureus and fungi respectively. Both S. aureus and the fungal load of the indoor environment were positively affected by the temperature of the room. Whereas, the floor space per inmate affects the concentration of S. aureus alone. Almost all rooms of the prison administration had microbial load beyond the acceptable limit. Higher temperature, less floor space per inmate, bad floor cleanness conditions, inadequate ventilation, and dampness were contributing factors to the high load of S. aureus and fungus. Thus, additional rooms are required to reduce overcrowding and keep room temperature.
