Are the classic signs of infection in concordance with results from percutaneous aspiration to diagnose infection in pressure injuries?

Evaluation and Management of Pelvic Osteomyelitis in Stage IV Pressure Injuries: A Multidisciplinary Collaborative Approach

Managing pelvic osteomyelitis (POM) in the setting of stage IV pressure injuries requires multidisciplinary evaluation as well as patient and caregiver engagement and is complicated by the lack of high-evidence data to guide best practices. In this review, we describe our approach to pressure injury and POM evaluation and management through multidisciplinary collaboration and highlight areas of future research that are necessary to enhance patient outcomes, reduce healthcare costs, and improve the quality of life of those affected by POM.

The roles of bedside nurses in Japan in antimicrobial stewardship

BACKGROUND

In the United States and the United Kingdom, the roles of nurses in antimicrobial stewardship (AS) have been described in guidelines. However, in Japan, no previous studies have clarified nurses' recognition of the role of AS. Moreover, how the AS roles were implemented among nurses in Japan has not been fully clarified. The objectives of this study were to determine the perceptions of infection control nurses (ICNs) in Japan regarding the AS role of nurses and the extent of nurses' practice.

METHODS

A questionnaire survey of ICNs was conducted.

RESULTS

Four hundred responses (response rate, 30.8%) were analyzed. Some of the items that have already gained consensus as the AS role of nurses were not recognized as the AS role of nurses by ICNs or had low implementation rates in Japan. Meanwhile, both recognition and implementation rates were high for the 5 types of care proposed.

DISCUSSION

The reason the ICNs agreed that these 5 types of care are AS roles for nurses is that they know that such care can prevent infection and thereby obviate the need for antimicrobial administration. However, whether nurses themselves understand that these are roles for nurses in AS is unclear. To promote AS in Japan, communicating the fact that nurses already contribute to AS, strengthening nurse education, and improving staffing are desirable.

The Association Between pH and Fluorescence as Noninvasive Diagnostic Tools in Chronic Wounds

MolecuLight i:X is a noninvasive, portable device that captures images, measures wound areas, and allows the evaluation of the bacterial environment in real time. The aim of the study was to correlate the different fluorescence (light green, red, cyan) and dark red-purple-black color areas with average pH values in these areas and with average wound bed score (WBS). During a 4-week period, we enrolled 43 adult patients (23 females and 20 males) with clinically infected and uninfected chronic ulcers. In our study, the mean age was 68 years old. The etiologies were 21 venous ulcers, 3 arterial ulcers, 4 vasculitis, 7 pyoderma gangrenosum, 7 traumatic ulcers, and 1 neoplastic ulcer. The average area was 16.92 cm² and the average WBS was 9.17. A total of 16 ulcers (37%) were positive for clinical signs and symptoms of infection and 27 ulcers were negative (63%). Thirty-six ulcers emitted a single fluorescence: cyan (n = 13), red (n = 1), light green (n = 14), and dark red-purple-black (n = 8). Six wounds showed a double fluorescence area: red and cyan (n = 1) and cyan and light green (n = 5). One ulcer emitted a triple fluorescence area: red, cyan, and light green. Overall in 43 ulcers, we found 43 fluorescence and 8 dark red-purple-black color. We found significant data between pH and fluorescence. pH values on wound bed confirm in a noninvasive way the correlation between fluorescence and bacterial burden. Moreover, MolecuLight i:X is able to detect objectively the bacterial proliferation, in contrast with pH which cannot distinguish different types of bacteria.
