ABSTRACT
BACKGROUND: Pressure injuries (PIs) represent a significant burden on the healthcare system and have a negative impact on the quality of life of those affected by these wounds. Despite best practice guidelines and other protocols to help healthcare facilities prevent PIs, the prevalence of PIs in Canada across all healthcare settings is concerning. OBJECTIVE: To describe the pattern of PI prevention and identify national priorities and opportunities to address PIs. METHODS: A descriptive, cross-sectional, online survey was created between August and December 2017 to explore Canadian healthcare professionals' knowledge, attitudes, and practices related to PIs. RESULTS: In total, 590 surveys were completed. Eighty-five percent of respondents confirmed that PIs occur in their work environments, and 29% claimed PIs are a frequent occurrence. Most of the respondents (91%) confirmed that they were part of a team that treats PIs. Of the 590 participants, 90% confirmed that they are aware of PI prevention devices and technologies. Between 80% and 90% attest to using offloading devices including prophylactic dressings to prevent PIs, but only 20% instituted measures to address moisture-associated skin damage. CONCLUSIONS: The findings from this survey have highlighted a disconnect between Canadian healthcare professionals' awareness of PIs and the implementation of best practices for PI prevention. It is evident that, although the majority of respondents were aware of PIs and related treatment protocols, barriers still exist that impede optimized care and treatment.

Aging leads to reduced cellular immunity with consequent increased rates of infectious disease, cancer, and autoimmunity in the elderly. The sympathetic nervous system (SNS) modulates innate and adaptive immunity via innervation of lymphoid organs. In aged Fischer 344 (F344) rats, noradrenergic (NA) nerve density in secondary lymphoid organs declines, which may contribute to immunosenescence with aging. These studies suggest there is SNS involvement in age-induced immune dysregulation. The purpose of this study was to longitudinally characterize age-related change in sympathetic innervation of the spleen and sympathetic activity/tone in male Brown Norway (BN) rats, which live longer and have a strikingly different immune profile than F344 rats, the traditional animal model for aging research. Splenic sympathetic neurotransmission was evaluated between 8 and 32 months of age by assessing (1) NA nerve fiber density, (2) splenic norepinephrine (NE) concentration, and (3) circulating catecholamine levels after decapitation. We report a decline in NA nerve density in splenic white pulp (45%) at 15 months of age compared with 8-month-old (M) rats, which is followed by a much slower rate of decline between 24 and 32 months. Lower splenic NE concentrations between 15 and 32 months of age compared with 8M rats were consistent with morphometric findings. Circulating catecholamine levels after decapitation stress generally dropped with increasing age. These findings suggest there is a sympathetic-to-immune system dysregulation beginning at middle age. Given the unique T-helper-2 bias in BN rats, altered sympathetic-immune communication may be important for understanding the age-related rise in asthma and autoimmunity.
