Barriers and facilitators to infection prevention practices in home healthcare: a scoping review and proposed implementation framework

Infection prevention and control (IPC) research has focused on the hospital setting, neglecting the rapidly expanding home healthcare (HHC) sector. Current infection prevention recommendations do not reflect the challenges specific to the HHC setting.

This scoping review considered any original studies reporting on barriers or facilitators to infection prevention practices in the context of HHC. Study characteristics were mapped, and a descriptive content analysis was performed. Based on the findings we propose a framework of eight HHC setting characteristics relevant to infection prevention implementation.

33 studies fulfilled the eligibility criteria. A majority of studies addressed sharps injury or blood and body fluid exposure prevention (N=15) and the majority were conducted in the United States (N=23). Study methodologies employed were surveys (N=18), qualitative (N=11), direct observation (N=7), and one interventional study. The HHC setting characteristics relevant to infection prevention implementation were: the care process in the patient's immediate environment; the need to bring equipment and materials into the home; the provision and financing of equipment and materials; the use of patient space and facilities; the unique position of and the expectations towards HHC providers; working alone with little support; the intermittent nature of care; the attitudes of HHC providers formed by their work circumstances.

Interventional studies generating higher-quality evidence for implementation are lacking. Furthermore, implementation of aseptic technique and the decontamination and reprocessing of equipment are poorly studied in the HHC setting and deserve more research interest. The proposed framework may guide future research and implementation work.
