Factors Associated with Acute Respiratory Infections in Children Aged 0 - 5 Years in the Yénawa District of Cotonou (Benin) in 2023

Introduction: Acute respiratory infections remain one of the main causes of mortality in children aged 0 to 5. This work aimed to study the associated factors with the occurrence of acute respiratory infections in children 0 to 5 years old in Yénawa, Cotonou in 2023. Subjects and Method: It was an analytical cross-sectional study of children aged 0 - 5 years and their mothers in Yénawa, selected by four-degree random sampling. The sampling size, calculated using the Schwartz formula, was 126 children and 126 mothers. The dependent variable was the occurrence of acute respiratory infections. The independent variables were classified into four groups: socio-demographic and economic characteristics, behavioral factors, child-related factors, and environmental factors. Data collected by observation and questionnaire survey were analyzed using STATA version 15 software. Associated factors were investigated by bivariate analysis and multiple logistic regression, at the 5% significance level. Results: A total of 126 children aged 0 - 5 years and 126 mothers were surveyed, aged 23.5 (11 - 36) months and 30 (18 - 48) years respectively. The prevalence of acute respiratory infections was 74.60% (CI95% = 66.89 to 82.30). The associated factors were the mother’s age between 18 and 28 (OR = 10.77;CI95% = 1.89 to 61.27;p = 0.007), the use of charcoal/wood for cooking (OR = 7.36;IC = 1.99 to 27.10;p = 0.003)), children's poor personal hygiene (OR = 8.87;IC = 2.92 to 26.97;p 0.001)), and cohabitation with domestic animals (OR = 7.27;IC = 1.67 to 31.71;p = 0.015). Conclusion: Communicating with mothers about the factors identified will help reduce the prevalence of acute respiratory infections in children aged 0 to 5.

Healthcare-Associated Infections: Experiences and Perceptions of Nurses at the Ziniaré District Hospital in Burkina Faso

Introduction: Healthcare-associated infections (HAIs) are a worldwide concern because of their magnitude and their human and financial cost. While nurses’ non-compliance of hygiene and asepsis measures is questioned, the rationale behind it is not fully understood. We hypothesized that nurses’ experiences and perceptions are one of the reasons for their non-compliance with prevention recommendations. Also, nurses’ caring approach would play an important role in patient safety. The objective of this study was to describe nurses’ experiences and perceptions of HAIs in a district hospital in Burkina Faso with the aim of developing a culture of safety in health care practices. Methods: Qualitative data were collected through unstructured interviews with twenty nurses from the Ziniaré district hospital. Data analysis followed the qualitative phenomenological method according to Giorgi. Results: Phenomenological analysis yielded the following themes: “an ignored reality”;“a denied responsibility”;and “a vulnerable problem”. These results show that nurses’ perception of the extent and seriousness of HAIs is low, and that they deny responsibility for their occurrence. As a result, HAIs are not always perceived as a concern. However, nurses deplore the situation, but remain optimistic about resolving the problem. Conclusion: These nurses’ perceptions of HAIs could explain their non-compliance with prevention recommendations. Corrective action could be redirected by raising awareness, continuing training, improving working conditions and involving all players, including patients and their families, in the fight against HAIs. .

Persistence of Healthcare-Associated (Nosocomial) Infections Due to Inadequate Hand Hygiene: Part 2—Human Factors

A healthcare-associated infection (defined as an infection acquired within a healthcare facility), such as due to transmission via medical equipment or by healthcare providers is the most frequent adverse event in the healthcare delivery system. But why does the problem persist, when infection control measures are known, simple, and low-cost? We reviewed some biological- and treatment-factors in Part 1, and we now review some human-factors. Healthcare-associated infections are a major public health problem even in advanced healthcare systems. They affect hundreds of millions of patients each year, and are responsible for increased morbidity, mortality, and financial burden. This is perplexing, since good-hygiene practices are known and promoted. Disinfection, sterilization, handwashing, and alcohol rubs should be more effective, but human-factors interfere. The persistent high prevalence of nosocomial infections, despite known hygienic practices, is attributable to two categories of factors: biological and inherent shortcomings of some practices (considered in Part 1), and human factors (considered here). A new approach is considered in Part 3.

Persistence of Healthcare-Associated (Nosocomial) Infections Due to Inadequate Hand Hygiene: Part 1—Biological and Treatment Factors

The most frequent adverse event in the healthcare delivery system is acquisition of an infection within a healthcare facility. Since infection control measures are known, simple, and low-cost, we examine why the problem of healthcare-associated infections persists. Hundreds of millions of patients each year are affected by a healthcare-associated infection, with negative medical outcome and financial cost. It is a major public health problem even in countries with advanced healthcare systems. This is a bit perplexing, given that hygienic practices have been known and actively promoted. The objective is to address the question: doesn’t the use of disinfection, sterilization, handwashing, and alcohol rubs prevent the spread of pathogenic organisms? We conclude that the persistent high prevalence of nosocomial infections despite known hygienic practices is attributable to two categories of factors: biological and inherent shortcomings of some practices (considered in Part 1), and human factors (considered in Part 2). A new approach is presented in Part 3.

Persistence of Healthcare-Associated (Nosocomial) Infections Due to Inadequate Hand Hygiene: Part 3—Application of Human Factors Engineering to an Ozone Hand Sanitizer

Compliance to hand-hygiene guidelines in healthcare facilities remains disappointingly low for a variety of human-factors (HF) reasons. A device HF-engineered for convenient and effective use even under high-workload conditions could contribute to better compliance, and consequently to reduction in healthcare-acquired infections. We present an overview of the efficacy of a passive hand-spray device that uses solubilized ozone—a strong, safe, non-irritant biocide having broad-spectrum antimicrobial properties—on glass surface, pigskin, and synthetic human skin matrix.

Healthcare-Associated Bacteremia and Urinary Tract Infections in Wards A and B of Medicine Department, CNHU-HKM of Cotonou: Characteristics and Risk Factors
