Workload and prevalence of open wounds in the community: French Vulnus initiative

Real-Life Data on Wound Healing Speed and Duration to Wound Closure by Different Aetiology in a Primary Care Centre in the Netherlands

Correct classification of wounds is of paramount importance for diagnostic and therapeutic pathways. The aim of this study was to provide insight in the incidence of different aetiology of wounds and the healing time in a primary care setting. All patients with a wound presented in Primary Care (PC) practice from January 2017 through 2020 were included. A retrospective analysis related to age, sex, duration of wound healing, healing-rates, aetiology and comorbidity of the patients was performed. The prevalence of wounds in primary care was is 3.9 per 1000. In more than 90% of the wounds heal within 37 days. The wound healing speed and duration to closure differ significantly (P = .002) between aetiology. This study shows that 90% of wounds that enter a Dutch GP practice heal within 37 days. This study provides unique data on wound healing rates differentiated by etiology.

Performance of a silicone foam dressing in management of wounds in a community setting: a sub-analysis of the VIPES study

OBJECTIVE

Managing the gap between the dressing and the wound bed can facilitate the healing of exuding wounds. A silicone foam dressing (Biatain Silicone; Coloplast A/S, Denmark) was developed for application to exuding wounds. A sub-analysis of the real-world, prospective, observational VIPES (Observatoire en Ville des Plaies ExSudatives) study was conducted to investigate the use and performance of the silicone foam dressing in a community nursing setting in France.

METHOD

The sub-analysis included patients from the VIPES study who received the silicone foam dressing as a primary dressing for an acute or hard-to-heal (chronic) wound. Epidemiological and wound healing outcomes were reported via a smartphone application.

RESULTS

Overall, 64 patients were included in the sub-analysis. At baseline, most wounds (n=33/40; 82.5%) were in treatment failure (i.e., were stagnant, non-healing or had poor exudate management). At the last follow-up visit, a median of 22.5 (range: 3-151) days post baseline, 48.4% of wounds had healed and 25.0% were progressing towards healing. From baseline to the last follow-up visit, significant reductions in exudate level (p<0.0001) and exudate pooling (p<0.0001), and significant improvements in wound edges (p≤0.0001) and periwound skin (p<0.01) were observed. A total of 62.3% of patients had re-epithelialising wounds at the last follow-up visit. The majority of nurses (88.3%) and patients (85.0%) reported that the wound had improved and, at most dressing removals (93.5%), nurses reported that the dressing conformed closely to the wound bed.

CONCLUSION

Overall, the data suggest that use of the silicone foam dressing in community practice supported the healing of wounds, illustrating the importance of exudate and gap management.

Multicentre Study of Chronic Wounds Point Prevalence in Primary Health Care in the Southern Metropolitan Area of Barcelona

Background: Chronic wounds give rise to major costs and resource consumption in health care systems, due to their protracted healing time. Incidence and prevalence data are scarce or nonexistent in community settings. Objective: The aim of the present epidemiological study was to analyse and determine the prevalence of chronic wounds in the community in the south of the province of Barcelona (Spain). Design: A cross-sectional, multicentre secondary data analysis study was conducted in the community (excluding nursing homes) in Barcelona between 16 April and 13 June 2013. It included 52 primary care centres that serve a total population of 1,217,564 inhabitants. Results: The observed prevalence was 0.11%. Venous ulcers presented the highest prevalence, at 0.04%, followed by pressure injuries, at 0.03%. The >74 age group presented the highest frequency of chronic wounds, accounting for 69.4% of cases. Conclusion: The results obtained are consistent with those reported in previous similar studies conducted in Spain and elsewhere. As with most studies that adjusted their variables for age and sex, we found that the prevalence of ulcers increased with age and was higher in women, except in the case of diabetic foot ulcers and ischaemic ulcers, which were more frequent in men.

Optimization of Best Practice Wound Care in the Netherlands

Estimates regarding the prevalence of chronic wounds in the Netherlands vary from 350 000 to 500 000. The cross-sectional multicenter study presented here provides evidence for the incidence and prevalence of wounds and chronic wounds. The primary aim of the present study was to provide evidence for incidence and prevalence of (chronic) wounds outside the hospital. The secondary aim was to optimize the organization for chronic wounds care within our region. From January 2017 until January 2018, information was prospectively collected of patients with new onset of wounds in 2 general practitioner practices to which 19 100 patients are enrolled. For the patients with new onset of wounds the “fast track protocol” was used and outcomes including etiology and wound healing were measured. This protocol included a structured treatment protocol and predetermined triage moments. The Alrijne Wound Centre database 2014 was used as a control group (469 records). The incidence of new onset of wounds was 364/19 100 (1.9%). The prevalence of wounds was 405/19 100 (2.1%). The prevalence of chronic wounds, that is, wounds that did not show a sufficient healing rate after 4 to 6 weeks, was 78/19 100 (0.4%). Time to referral to a wound physician (the triage moment) was 5 weeks versus 19 weeks in 2014 ( P < .001). Unnecessary referrals to the hospital was reduced by 17.4% ( P = .007). In conclusion, the prevalence of the chronic wounds was 4 per 1000 patients. The use of the “fast track” protocol optimizes wound care, wounds heal faster, and unnecessary referrals decrease significantly.

[Observational study of the second-line nursing consultation in wounds and scarring: A didactic situation under construction]

Introduction and objective : In the activity of wound and scar nurses (Infirmières spécialisées en plaies et cicatrisation ; ISPC), the "second-line" nursing consultation is also an opportunity to offer applicants the opportunity for training. This study is part of an exploratory perspective, with the objective of questioning the didactic dimension of this type of consultation. To address the issue, attention is focused on the analysis of the ISPC's activity.Material and method : Two simple self-confrontation interviews of an ISPC are analyzed on the basis of video consultations.Results and discussion : Although the results identified remain incomplete since the interviews were based on a single individual, this article shows how the ISPC, after the interviews, is able to formulate future adjustments to their practice. The first avenue is to highlight a necessary transformation of the discourse of the ISPC during consultations. The second is to question the modality of the post-consultation follow-up.

[Nurses' management of chronic wounds: A comparative review of pedagogical practices in initial training in France and Lorraine]

INTRODUCTION

Managing chronic wounds is a large part of a nurse's role. However, this complex mission requires nursing professionals to have a wide knowledge base.

OBJECTIVE OF THE STUDY

The objective is to undertake a comparative review of pedagogical practices used to teach nursing students about chronic wounds in French nursing training institutes (compared to nursing training institutes in Lorraine).

METHOD

A survey was carried out using a self-administered online questionnaire disseminated via the national nursing training network Cefiec, between February and April 2018. It contained 21 questions.

MAIN RESULTS

34.8% of nursing training institutes have a teacher with a university diploma in wounds and healing. Only 30.4% offer hospital-based clinical teaching on this topic. In Lorraine, 40% of nursing training institutes cover the preparation of the wound bed using the TIME model, and 20% cover debridement, compared to 40% and 7.5% nationally.

DISCUSSION

Teaching content varies greatly depending on the training institute, and shows that there is a theoretical and practical deficiency in teaching on topics including preparing the wound bed, debridement, and venous compression. Collaboration with expert nurses and referral hospitals is common. Teachers still do not have sufficient access to continuing training and scientific journals.

[Medical residents and wound healing: A French national survey]

OBJECTIVES

Around 2.5 million wounds are recorded in France, representing, in terms of cost and quality of life, a real problem of public health issue. In France, residents are among the first line personnel having to manage wounds and their complications: this study is carried out to identify the view and feelings of residents concerning their preparation and training in this field.

MATERIALS AND METHODS

A questionnaire was distributed to residents throughout France. Residents' characteristics, interests and training in wound healing, training courses and opinions concerning their training were recorded.

RESULTS

Seven hundred and eleven French residents answered the questionnaire, the majority of whom (79 %) had not experienced training in wound healing. The majority of residents (69 %) believe that all physicians are concerned. Training in wound management and wound healing is considered insufficient (94 %) and most (79 %) had never received any training in wound management and wound healing. Ninety-eight percent stated they needed additional training courses in wound management.

CONCLUSIONS

Wound management and healing is a topic of interest to residents. Residents need more training in wound management in their curriculum to improve their practice.

[Free flaps use in chronic wounds: Retrospective study about 91 cases]

INTRODUCTION

Chronic wounds represent a major health challenge with no current standardized surgical treatment. The use of free flaps is little discussed in the literature, with a supposed propensity to failure given unfavorable local conditions and land often debility. We present here the analysis of our monocentric experience of the use of free flaps in the curative treatment of chronic wounds.

PATIENTS ET METHODS

We performed a retrospective monocentric study over 18 years of all free flaps used for the treatment of a chronic wound between January 2001 and September 2016. Several criteria were evaluated on patients, wounds, free flaps used and immediate to late outcomes.

RESULTS

Ninety-one patients were included (sex ratio M/F: 3.55) with an average age of 41.6±16 years. Wounds were localized to the leg in 92.3% of cases and 58% of patients had initial osteomyelitis. The flaps used were predominantly muscle flaps (61.6%). The flaps survival rate was 92.3%. With a mean follow-up of 50 months, the reconstructive failure rate was 20.9%. The presence of a chronic osteomyelitis is the only statistically significant factor of reconstruction failure (P=0.0169) with a risk of failure multiplied by 5.

CONCLUSION

Our study demonstrates that the reliability of free flaps in the treatment of chronic wounds is comparable, regardless of the time since the initial cutaneous lesion, to that existing in the treatment of acute wounds or in the reconstruction after oncological excision. The presence of a chronic osteomyelitis, however, represents a major risk of reconstruction failure by increasing 5 times the risk of failure. Recent changes in the integumentary reconstruction paradigm of the lower limb will undoubtedly allow in the next few years to establish more rationally the place of muscle free flaps in the therapeutic armamentarium of chronic wounds.

The impact of an educational intervention on home support workers' ability to detect early pressure ulcer damage

OBJECTIVE

To investigate the impact of an educational intervention on home support workers' ability to detect early pressure ulcer damage.

METHOD

A repeated measure design was employed to quantify the effectiveness of an educational intervention, consisting of one pre-test and two post-tests.

RESULTS

Education was provided to home support workers and this was followed by an assessment of their ability to correctly classify 20 photographs detailing varying stages of skin damage severity. At the baseline (pre-education), 58% of the photographs were classified correctly. At post-test 1, 55% of the photographs were classified correctly. In post-test 2 this increased to 58%, achieving the original baseline scores. There was a moderate negative relationship between pre-training and post-test 2 scores (r=-0.44; n=27; p=0.02).

CONCLUSIONS

The educational intervention has been shown not to have a statistically significantly positive effect on home support workers' ability to detect early pressure ulcer damage. The moderate negative relationship between pre-training and post-test 2 scores concur with the aforementioned qualitative findings, and similarly indicate behaviour associated with individuals experiencing difficulty comprehending new health terms.

Protease-modulating polyacrylate-based hydrogel stimulates wound bed preparation in venous leg ulcers--a randomized controlled trial

Background

Stringent control of proteolytic activity represents a major therapeutic approach for wound-bed preparation.

Objectives

We tested whether a protease-modulating polyacrylate- (PA-) containing hydrogel resulted in a more efficient wound-bed preparation of venous leg ulcers when compared to an amorphous hydrogel without known protease-modulating properties.

Methods

Patients were randomized to the polyacrylate-based hydrogel (n = 34) or to an amorphous hydrogel (n = 41). Wound beds were evaluated by three blinded experts using photographs taken on days 0, 7 and 14.

Results

After 14 days of treatment there was an absolute decrease in fibrin and necrotic tissue of 37.6 ± 29.9 percentage points in the PA-based hydrogel group and by 16.8 ± 23.0 percentage points in the amorphous hydrogel group. The absolute increase in the proportion of ulcer area covered by granulation tissue was 36.0 ± 27.4 percentage points in the PA-based hydrogel group and 14.5 ± 22.0 percentage points in the control group. The differences between the groups were significant (decrease in fibrin and necrotic tissue P = 0.004 and increase in granulation tissue P = 0.0005, respectively).

Conclusion

In particular, long-standing wounds profited from the treatment with the PA-based hydrogel. These data suggest that PA-based hydrogel dressings can stimulate normalization of the wound environment, particularly in hard-to-heal ulcers.

Bacterial floras and biofilms of malignant wounds associated with breast cancers

The risk of infections and the appearance of symptoms (e.g., odors) represent the main troubles resulting from malignant wounds. The aim of this study was to characterize the balance of bacterial floras and the relationships between biofilms and bacteria and the emergence of symptoms. Experimental research was carried out for 42 days on malignant wounds associated with breast cancer. Investigations of bacterial floras (aerobes, aero-anaerobes, and anaerobes), detection of the presence of biofilms by microscopic epifluorescence, and clinical assessment were performed. We characterized biofilms in 32 malignant wounds associated with breast cancer and bacterial floras in 25 such wounds. A mixed group of floras, composed of 54 different bacterial types, was identified, with an average number per patient of 3.6 aerobic species and 1.7 anaerobic species; the presence of strict anaerobic bacterial strains was evidenced in 70% of the wounds; biofilm was observed in 35% of the cases. Odor was a reliable indicator of colonization by anaerobes, even when this symptom was not directly linked to any of the identified anaerobic bacteria. Bacteria are more likely to be present during myelosuppression and significantly increase the emergence of odors and pain when present at amounts of >10(5) · g(-1). The presence of biofilms was not associated with clinical signs or with precise types of bacteria. No infections occurred during the 42-day evaluation period. This study provides a dynamic description of the bacterial floras of tumoral wounds. The study results highlight the absolute need for new therapeutic options that are effective for use on circulating bacteria as well as on bacteria organized in biofilm.

Bacterial isolates from infected wounds and their antibiotic susceptibility pattern: some remarks about wound infection

Wound infection plays an important role in the development of chronicity, delaying wound healing. This study aimed to identify the bacterial pathogens present in infected wounds and characterise their resistance profile to the most common antibiotics used in therapy. Three hundred and twelve wound swab samples were collected from 213 patients and analysed for the identification of microorganisms and for the determination of their antibiotic susceptibility. Patients with diverse type of wounds were included in this retrospective study, carried out from March to September 2012. A total of 28 species were isolated from 217 infected wounds. The most common bacterial species detected was Staphylococcus aureus (37%), followed by Pseudomonas aeruginosa (17%), Proteus mirabilis (10%), Escherichia coli (6%) and Corynebacterium spp. (5%). Polymicrobial infection was found in 59 (27·1%) of the samples and was mainly constituted with two species. The most common association was S. aureus/P. aeruginosa. All Gram-positives were susceptible to vancomycin and linezolid. Gram-negatives showed quite high resistance to the majority of antibiotics, being amikacin the most active against these bacteria. This study is mostly oriented to health care practitioners who deal with wound management, making them aware about the importance of wound infection and helping them to choose the adequate treatment options to control microbial infection in wounds.
