Validity and reliability of semi-quantitative wound swabs

Content of a wound care mobile application for newly graduated nurses: an e-Delphi study

BACKGROUND

Wound care represents a considerable challenge, especially for newly graduated nurses. The development of a mobile application is envisioned to improve knowledge transfer and facilitate evidence-based practice. The aim of this study was to establish expert consensus on the initial content of the algorithm for a wound care mobile application for newly graduated nurses.

METHODS

Experts participated in online surveys conducted in three rounds. Twenty-nine expert wound care nurses participated in the first round, and 25 participated in the two subsequent rounds. The first round, which was qualitative, included a mandatory open-ended question solicitating suggestions for items to be included in the mobile application. The responses underwent content analysis. The subsequent two rounds were quantitative, with experts being asked to rate their level of agreement on a 5-point Likert scale. These rounds were carried out iteratively, allowing experts to review their responses and see anonymized results from the previous round. We calculated the weighted kappa to determine the individual stability of responses within-subjects between the quantitative rounds. A consensus threshold of 80% was predetermined.

RESULTS

In total, 80 items were divided into 6 categories based on the results of the first round. Of these, 75 (93.75%) achieved consensus during the two subsequent rounds. Notably, 5 items (6.25%) did not reach consensus. The items with the highest consensus related to the signs and symptoms of infection, pressure ulcers, and the essential elements for healing. Conversely, items such as toe pressure measurement, wounds around drains, and frostbite failed to achieve consensus.

CONCLUSIONS

The results of this study will inform the development of the initial content of the algorithm for a wound care mobile application. Expert participation and their insights on infection-related matters have the potential to support evidence-based wound care practice. Ongoing debates surround items without consensus. Finally, this study establishes expert wound care nurses' perspectives on the competencies anticipated from newly graduated nurses.

IWII Wound Infection in Clinical Practice consensus document: 2022 update

ABSTRACT

Wound infection is a major challenge for clinicians globally, with accurate and timely identification of wound infection being critical to achieving clinical and cost-effective management, and promotion of healing. This paper presents an overview of the development of the International Wound Infection Institute (IWII)'s 2022 Wound Infection in Clinical Practice consensus document. The updated document summarises current evidence and provides multidisciplinary healthcare providers with effective guidance and support on terminology, paradigms related to biofilm, identification of wound infection, wound cleansing, debridement and antimicrobial stewardship. Integral to the update is revision of wound infection management strategies which are incorporated within the IWII's Wound Infection Continuum (IWII-WIC) and management plan. The aim of the 2022 IWII consensus document update was to provide an accessible and useful clinical resource in at least six languages, incorporating the latest evidence and current best practice for wound infection and prevention. Dissemination techniques for the consensus are discussed and highlighted.

Wound infection: A review of qualitative and quantitative assessment modalities

Surgical site infections (SSI) and chronic wounds represent a burden to patients and the health care system. One in 24 surgical patients will develop an SSI, making SSI the most common nosocomial infection in the USA. Early detection and monitoring of wound infection are critical for timely healing and return to normal function. However, the mainstay of wound infection diagnostic entails subjective clinical examination and semi-quantitative, invasive microbiological tests. In this review, we present current wound infection assessment modalities in the clinical and translational fields. There is a need for a point-of-care assessment tool that provides fast, accurate, and quantitative information on wound status, with minimal to no contact with the patient. In the next ten years, the evolution of wound diagnostic tools reported here may allow medical providers to optimize patient care while minimizing patient discomfort.

A double blind randomized controlled trial using copper impregnated maternity sanitary towels to reduce perineal wound infection

OBJECTIVE

To investigate the effect of copper impregnated sanitary towels on the infection rate following vaginal delivery (VD).

DESIGN

Single center double blind randomized controlled trial.

PARTICIPANTS

Women aged 18 or over who had a sutured second-degree tear or episiotomy following VD.

INTERVENTIONS

All women were randomized to receive either a copper-oxide impregnated sanitary towel (study group) or a non-copper sanitary towel (control group).

MAIN OUTCOME MEASURES

The primary study outcome was the incidence of wound infection within a 30-day period from VD, assessed via telephone questionnaire. Secondary outcomes were length of hospital stay and risk factors of infection.

RESULTS

450 women were enrolled in the study of whom 225 were randomized to the copper impregnated sanitary towel (study group) and 225 to the non-copper sanitary towel (control group) group. Follow-up rate was 98.2%. A total of 102 women (23.1%) developed an infection within 30 days following VD, 19 in the study group (8.6%) and 83 (37.4%) in the control group (P = <0.001, absolute risk reduction (ARR) of 28.8%). The incidence of superficial/deep and organ/space infections was significantly lower in the study group (7.7% vs. 30.2%, P = <0.001 and 4.6% vs. 31.5%, P = <0.001 respectively) with an ARR of 22.5% and 27.0% respectively. Multivariable analysis reported Asian ethnicity and prolonged rupture of membranes as significant risk factors; for the development of infection (OR 1.91, P = 0.03 and OR = 1.97, P = 0.04 respectively).

CONCLUSIONS

This is the first study to demonstrate a significant reduction in infection rate following VD with the use of copper impregnated sanitary towels.
