Survey of patients of the Tver region of Russia regarding maggots and maggot therapy

Maggot therapy for resistant infections: the disconnect between scientific evidence, clinical acceptance and practice

OBJECTIVE

Practitioners and scientists are re-examining marginalised wound care therapies to find strategies that combat the growing problem of antimicrobial resistance (AMR) without compromising patient outcomes. Maggot therapy (MT) makes up just an estimated 0.02% of UK's National Health Service spending on wound care. This study aims to uncover why MT is not used more often, despite its affordability and high level of efficacy for both debridement and disinfection, particularly in the context of AMR infections, and to determine what can be done to ensure MT is more effectively used in the future to improve patient outcomes and manage the growing problem of AMR.

METHOD

For this investigation, a qualitative review of case studies using MT against AMR infections and a quantitative analysis of randomised control trials (RCTs) were performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework.

RESULTS

Analysis showed that MT is highly effective against a range of infections and wound types, and compares well against conventional therapies. The low use of MT may be due in part to the documented 'yuck factor', often associated with maggots as well as misconceptions around the cost, efficacy and accessibility of MT. To overcome these factors, more RCTs on the spectrum and efficacy of MT across various clinical manifestations are needed, as well as professional and public engagement campaigns.

CONCLUSION

MT is an underused therapy, particularly regarding AMR infections, and expanding its use in these circumstances appears warranted. MT could play a vital role in conserving the efficacy of the existing pool of antimicrobials available and should be considered in the development of antimicrobial stewardship programmes.

Pain Assessment in Patients Undergoing Maggot Debridement Therapy in the Process of Local Treatment of Chronic Wounds

(1) Background: Developing and implementing strategies for local wound care focused on improving the quality of life related to health status and reducing treatment costs for this patient group poses a challenge to contemporary healthcare systems. The utilization of Maggot Debridement Therapy (MDT) is one potential form of local therapy for preparing wounds for the healing process. The debridement of the wound bed with medical maggots is highly precise, and the defensins produced by the larvae eliminate bacteria and stimulate tissue regeneration. However, the presence of larvae in the wound may lead to the occurrence of pain symptoms. The aim of the study was to assess the intensity of pain during larval therapy in patients with chronic wounds treated in outpatient settings. (2) Patients and Methods: The study employed a diagnostic survey and estimation; the tool consisted of a research protocol comprising three parts (questionnaires). Inclusion criteria for the study were voluntary consent to participate (completion of the MDT acceptance questionnaire), chronic wounds of vascular etiology or pressure injuries, full-thickness skin or deep tissue damage, and pain intensity not exceeding four on the NRS (Numerical Rating Scale: 0-no pain, 10-the most severe pain) at the time of the study. Patient observation during the 3-day treatment was conducted by a wound care clinic nurse, assessing pain intensity once every 24 h during the larval dressing changes. (3) Results: Out of 348 individuals who qualified for MDT during the study period, 215 individuals participated in the study: 94 women (43.7%) and 121 men (56.3%). The age of the participants ranged from 28 to 97 years (mean 69.87 ± 12.95). Each participant experienced mild pain (2.26 ± 1.60 on the NRS) on the day of qualification for the study. An increase in pain intensity, according to subjective assessments, was reported by 29.3% of participants (n = 63). On the third day of MDT therapy, an increase in pain intensity was observed, reaching a mean value of 4.79 ± 2.12 (p < 0.0001). Participants with pressure injuries showed the lowest pain intensity, which increased in consecutive days for all types of wounds. Additionally, the increase in pain intensity in patients with vascular etiology wounds was greater compared to patients with pressure injuries (p < 0.001). (4) Conclusions: Local wound therapy with Lucilia sericata larvae increases pain intensity in the consecutive days of treatment. The wound area and the time since its occurrence may determine pain symptoms.

Variables Associated with Attitudes toward Biodebridement Using Lucilia sericata Larvae in a Group of Nurses

Despite numerous studies and recommendations, the acceptance of treatments involving medicinal maggots in many clinics has been slow. Several factors may account for this, including the gender of nurses administering the treatment, their level of work experience, and their perceived level of personal stress. The aim of the study was to assess the impact of selected variables (gender, work experience, stress level) on the readiness of nurses to administer maggot debridement therapy (MDT), which is a form of biodebridement. The study population was a cohort of 290 wound care nurses providing specialist care for patients with chronic wounds. It was assumed that the identified variables may determine the implementation of larval therapy in everyday professional practice. A subsample of 35 men and 35 women was further analyzed to determine if gender, work experience, and/or personal stress levels were correlated with attitudes towards the utilization of maggots in biodebridement. Assessment tools included the Perceived Stress Scale (PSS-10) and the MDT 10 Perception Assessment Questionnaire, a protocol by which the subject ranked six wound photographs in order of repulsiveness and responded to questions regarding demographic variables, which include education and work experience. The visual perception of pictures of a wound with larvae is indirectly an indicator of the attitude towards larval therapy. Selection of the photograph with maggots on the wound as the most repulsive image was associated with a personal appraisal of not being ready to implement maggot therapy (chi-square = 8.430, p = 0.015). Low work experience (chi-square = 14.039, df = 4, p = 0.007), and low readiness for MDT (chi-square = 8.430, df = 2, p = 0.015) were also associated with unpreparedness to administer maggot therapy. Neither gender nor perceived stress level were exclusively associated with disgust for maggots or lack of readiness to implement MDT. Low professional experience and a deficit of knowledge in maggot therapy may negatively affect the readiness of nurses to administer biodebridement. Gender and personal stress levels do not affect nurses' readiness to utilize larval therapy.

Larval Wound Therapy: Possibilities and Potential Limitations-A Literature Review

Patient-centered care (PCC) is recognized as a standard in healthcare for determining high quality. Honoring patients' values, experiences, needs, and preferences in devising, coordinating, and delivering care underscores the enhancement of the therapeutic rapport between patients and healthcare providers. Wound treatment involves a multi-stage process encompassing diagnostics and local wound dressing, which reduces the risk of infection through a coordinated interdisciplinary team. Within this team, nurses undertake specific professional functions and roles. The implementation of local therapy using innovative and scientifically substantiated methods may be hindered by a deficit of knowledge or inappropriate knowledge among staff and patients themselves. This study presents the challenges concerning the care of patients with chronic wounds treated using Lucilia sericata larvae, based on a review of the current scientific literature. A critical analysis of the literature spanning from 2002 to 2022 was conducted using the Medline, PubMed, Cochrane, and Termedia databases, employing keywords such as "maggot debridement therapy" in relation to acceptance and perception. As a result of the preliminary selection, 472 papers were identified, of which 12 publications were included in the development of this concept. The acquired data were organized and presented in the concluding section in the form of tables, accompanied by descriptions and references to individual studies. Negative psychological and somatic sensations were among the most prominent challenges among patients treated with Maggot Debridement Therapy (MDT). Pain related to peripheral ischemia or infection in this group of patients requires pain prophylaxis, including hyperalgesia and allodynia, in order to improve method tolerance. On the other hand, augmenting patients' understanding of MDT diminishes negative emotions, reinforces positive behaviors, and mitigates anxiety levels. MDT constitutes an effective and safe method. Its widespread use for chronic wounds requires substantial knowledge among healthcare professionals and patient education, along with that of their caregivers, to develop a positive attitude.

Nurses' Readiness to Undertake Controlled Negative Pressure Therapy in the Treatment of Chronic Wounds-Research Report

Local wound treatment with negative pressure wound therapy (NPWT) shortens the healing process but requires the supervision of trained medical personnel for administering the therapeutic procedures. Professional supervision and control of the effectiveness of NPWT, as well as education conducted by nurses, are of particular importance for therapeutic and caring processes, both in hospital and at home. The aim of the study was the assessment of the perception of NPWT by certified nurses in the topical treatment of chronic wounds. The study was conducted using the method of estimation and a diagnostic survey with the proprietary NPWT perception questionnaire: 495 subjects were enrolled in the study and 401 respondents aged 25-67 years qualified for statistical analysis. Despite their experience and competence, the respondents critically assessed their knowledge, pointing to an average subjective level of knowledge related to wound treatment and a low level of knowledge related to NPWT. Most of the respondents had no experience of independent treatment using this method. The data obtained from the questionnaire clearly indicate theoretical preparation and high motivation to undertake activities related to the implementation of NPWT in their own practice. Low readiness values suggested that the subjects did not have the resources or the ability to implement the method. The perception of NPWT in the surveyed group of nurses was determined by numerous factors, including self-assessment of their own knowledge, motivation and readiness to use NPWT. A high level of NPWT perception was noted, despite low motivation related to the availability and knowledge of the method. Theoretical knowledge is insufficient to implement innovative methods in local wound treatment. Practical skills and motivation are indispensable elements that should be met during the training and education of nurses in the field of wound care.

Perceived stress and readiness to undertake biodebridement in the group of nurses undertaking prevention and treatment of chronic wounds

Introduction

Stress as the body's response to adverse stimulus is recognized as one of the key problems in basic and clinical neurological studies. Stress is an indispensable component of modern nursing with its low doses being desirable, however, prolonged stress is detrimental to health increasing the risk of chronic disease i.e., hypertension, cardiovascular diseases, electrolyte disturbances, occupational burnout, depression, anxiety disorders. The implementation of certain techniques and therapeutic methods may have a stressful effect from the point of view of practice and the patient's condition.

Methods

The authors undertook the study to assess the intensity of the perceived stress in the group of nurses dealing with wound care in the perspective of implementing wound debridment using Lucilia sericata larvae. The study group consisted of 290 nurses specialized in chronic wounds undergoing training at the Postgraduate Training Center of Nurses and Midwives in Rzeszów, out of the entire group of 1.136 individuals participating in training courses organized in Poland in 2020-2021. The study used the diagnostic survey method, the research tool was a scientific research protocol consisting of tools (MDT perception questionnaire, perceived stress scale (PSS-10).

Results

Certain differences in the level of stress in the study sample were observed between age categories, but they were not statistically significant. The greatest differences between the levels of stress in the study sample were observed between people who completed treatment courses and those who did not complete these courses. The higher the stress level, the lower the willingness to undertake such therapy. The analysis of grouped data leads to interesting observations. There were statistically significant differences in the score in the MDT10 scale in the categories of people with different stress levels. The highest readiness to implement MDT was observed in the category of people with the lowest perceived level of stress.

Conclusions

The level of professional experience related to postgraduate education increases opportunities addressing new professional challenges. The level of perceived stress may influence decisions related to the use of biological therapy. The higher the level of stress, the lower the readiness to undertake MDT.

Evaluating nursing opinion and perception of maggot therapy for hard-to-heal wound management

OBJECTIVE

Maggot therapy (MT) or larval debridement therapy is a recognised, effective but underutilised treatment for the management of hard-to-heal wounds and infected ulcers. It is available on NHS prescription in the UK, where wound management is predominantly nurse-led. Anecdotal reports and published literature suggest that nurses may be reluctant to utilise the therapy. The aim of this study was to evaluate the feelings and opinions of nurses regarding the use of MT.

METHOD

The first stage of this mixed-methods study was a focus group held to discuss MT and opinions of specialist nurse clinicians. Next, an anonymised web-based online survey was launched through the Nursing Times journal and distributed through social media targeting all nurses. Finally, in-depth interviews were held with specialist and generalist nurses.

RESULTS

Awareness of MT among all nurses was extremely high. A breakdown of results showed that MT was much more highly regarded by wound specialist nurses than non-wound specialist nurses. The latter exhibited a greater level of reluctance to administer the therapy, with almost one-third of these nurses surveyed saying they found maggots disgusting and that the idea of MT made their skin crawl. In-depth interviews revealed that a lack of knowledge about MT was a prime concern.

CONCLUSION

Wound specialist nurses are more likely to embrace MT than non-wound nurse specialists, who report a varying degree of wariness to MT. Our study highlights a need for better education and training in MT for all nurses, to address issues with acceptance and willingness to treat or help treat patients with hard-to-heal wounds which are suitable for MT.

An exploration of public perceptions and attitudes towards maggot therapy

OBJECTIVE

The aim of the study was to explore public opinion and perceptions of maggot therapy (larval therapy), a treatment option for hard-to-heal wounds.

METHOD

The study used a mixed-method approach to obtain quantitative and qualitative data. A focus group was convened to explore opinions and views of maggot therapy with a small group of members of the public. Analysis of emerging themes from the focus group was used to design an anonymised web-based survey, which was made available online to members of the public through email and social media.

RESULTS

The focus group participants identified four key themes concerning the acceptability of maggot therapy. The subsequent online survey was completed by 412 participants, analysis of which revealed some worries and fears. Only 36% of survey participants agreed that they would accept maggot therapy as a first choice for a hypothetical painful wound, although this number increased with wound severity. The most predominant concerns regarding maggot therapy were sensation and a feeling of disgust associated with the therapy. However, participants could see some benefits to maggot therapy.

CONCLUSION

Our study showed that public perception of maggot therapy is varied. Survey participants expressed worries and fears associated with its use. However, positive relationships existed between knowledge scores and potential acceptability of maggot therapy, suggesting that information dissemination and education may be an important factor in public perception and acceptability of maggot therapy.

Radiofrequency ablation of varicose veins in combination with ultrasonic-assisted wound debridement and platelet-rich plasma as well as platelet-rich fibrin technologies in treatment of lower extremity venous ulcers in office-based surgery

INTRODUCTION

for the treatment of varicose ulcer performed clinical and laboratory reasoning of the use of ultrasonic-assisted venous ulcer debridement and Platelet-rich plasma with radiofrequency ablation in an outpatient setting, was carried out.

METHODS

ultrasonic-assisted debridement of trophic ulcer were performed for 50 patients with lower extremity varicose veins at decompensation stage. The effectiveness of ultrasonic-assisted debridement was evaluated by indicators of bacteriological, morphological, cytological study and assessment of trophic ulcers according to the MEASURE system. After ultrasonic-assisted debridement, the patients were divided into two groups: 30 patients, who underwent combined Platelet-rich plasma to stimulate wound regeneration and 20 patients, for whom the Granuflex hydrocolloid bandage was applied for the same purpose.

RESULTS

a comparative analysis of ulcer regeneration in two groups of patients proved that in cases of platelet rich plasma the time of transition from inflammatory-regenerative type to regenerative one is much shorter than when using a hydrocolloid dressing. In 28 patients undergoing Platelet-rich plasma (PRP) and Platelet-rich fibrin (PRF), the radiofrequency ablation of the principal superficial and perforating veins was performed. Another 22 patients performed autodermoplasty of trophic ulcers after radiofrequency ablation.

CONCLUSION

our experience has shown that in a one-day inpatient surgical clinic such a multidisciplinary approach to treatment of venous ulcers, including ultrasonic-assisted debridement that is stimulation of wounded process by Platelet-rich plasma with further surgeries to remove the causes of decompensated chronic insufficiency, is promising regarding low costs of treatment and rehabilitation of these patients.

Perception and Readiness to Undertake Maggot Debridement Therapy with the Use of Lucilia sericata Larvae in the Group of Nurses

The sight and smell of larvae in the wound may cause negative visual and olfactory impressions in sensitive individuals because of decaying body parts, carrion, and suffering. However, Maggot Debridement Therapy (MDT) is highly effective, safe, and cheap in wound healing and tissue revitalization for both the patient and health systems. The aim of the study was to assess the readiness to undertake MDT in a group of qualified nurses who perform therapeutic procedures in patients treated for chronic wounds. A diagnostic survey was used. The research tool was a scientific research protocol consisting of three questionnaires (sociodemographics, MDT perception questionnaire, pictures of wounds for visual assessment). The study included 290 nurses; the mean age was over 42.6 ± 9.9 years, and the median was 44 years. The perception and readiness to implement the method in the tested sample is at the average (standard) level. The image of maggots in the wound causes negative emotions among medical personnel. The higher the knowledge of the MDT method, the greater the motivation to implement it in practice.

Advantages of Maggot Debridement Therapy for Chronic Wounds: A Bibliographic Review

GENERAL PURPOSE

To present an overview of the advantages of maggot debridement therapy as a treatment for chronic wounds through the review of several larval properties.

TARGET AUDIENCE

This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.

LEARNING OBJECTIVES/OUTCOMES

After participating in this educational activity, the participant will be able to:1. Summarize the use, process, and precautions for maggot debridement to treat chronic wounds.2. Synthesize the results of the bibliographic review of the use of maggot debridement to treat chronic wounds.

ABSTRACT

Maggot debridement therapy (MDT) is effective for ulcer debridement, achieving it in less time than other therapies. It offers a benefit to healing. However, it is unclear whether maggots reduce treatment time and there is considerable controversy around the treatment's potential antimicrobial action and cost-effectiveness. Nevertheless, it can be effective in preventing amputations and reducing the need for systemic antibiotics. This bibliographic review assesses the advantages of MDT as a treatment for chronic wounds through the review of several larval properties. The review was carried out by consulting biomedical databases including CINAHL, MEDLINE (PubMed), and Scopus, and concludes that MDT is an effective debridement and potential technique to facilitate healing. However, more data is needed on the wound type application frequency and the efficacy of treatment.

Survey of patients of the Tver region of Russia regarding maggots and maggot therapy

The 21st century is seeing a resurgence in the use of maggot therapy-using the physical and biochemical benefits of fly larvae to debride and heal chronic, problematic wounds. Maggots are repulsive to many people, and this could interfere with the acceptance of this modality. Before instituting a maggot therapy programme at our institution, we sought to better understand the psychological barriers that may exist among patients in the Tver region of Russia. Between 2014 and 2016, all patients with arterial insufficiency and trophic ulcers at City Clinical Hospital No. 7 in Tver were administered a survey consisting of six images. Subjects were asked to rank the images in the order of least to most repulsive or disgusting. A total of 576 subjects were recruited for this study: 414 (72%) women and 162 (28%) men. Nearly 60% of subjects considered the images of maggots to be more repulsive than images of gangrenous wounds. This finding is significant because it indicates that much education and support will need to be conducted to address patient fears and anxiety if patients are to be comfortable with a maggot therapy programme.
