| Summary: | Abstract Worldwide, home care in the form of home healthcare and home help, has become increasingly more available. This systematic review aims to provide a deeper understanding of factors that are of particular importance for infection control in the home care setting for older adults. Five databases were searched (MEDLINE, Embase, ProQuest, Web of Science, CINAHL) for eligible studies using any research design reporting on individual, medical, behavioral and environmental factors. Retrieved studies were screened and assessed for quality. The Joanna Briggs Institute manual guided the research process and the work of generating a synthesis. Qualitative findings were compiled using meta-aggregation. For quantitative evidence, meta-analyses were conducted when possible. Of 19,484 unique records, 27 studies (7 cohort studies, 9 cross-sectional and 11 qualitative) were included in the review. Risk factors for infection reported in the quantitative studies referred to individual, medical, social, behavioral, environmental, and organisational aspects. Meta-analyses showed associations between urinary catheter use (OR 3.97, 95%CI 2.56–6.15) and limited mobility (OR 1.49, 95%CI 1.31–1.68), respectively, and risk of infection. Pooled ORs of urinary incontinence and risk of infection were not statistically significant. Findings from the qualitative studies covered perceived and observed risk factors to infection control and prevention. The evidence resulted in five synthesised findings covering attitudes, behaviors, home environment, personal interactions, lack of equipment, unsafe disposal of material, pets, unsafe practices and procedures, and lack of training. The combined quantitative and qualitative evidence sheds light on separate yet interconnected elements of risks for infection that may reinforce each other, potentially exposing vulnerable older adults to amplified risks. |
