Resigning oneself to a life of wound-related odour - A thematic analysis of patient experiences.

AIMS: To determine how patients with chronic wounds describe wound odour, identify what strategies they use to manage it and how effective these are. MATERIALS AND METHODS: Using a qualitative descriptive approach, semi-structured interviews were conducted between July and August 2021 with seven patients living with an odorous chronic wound at home. Data were analysed using Braun and Clarke's thematic analysis framework. RESULTS: The results were organised into two main themes: 1) becoming resigned to living with wound-related odour 2) strategies used to manage wound-related odour. Participants were sad, embarrassed and felt isolated but became resigned to living with this odour and accepting of it as a consequence of having a wound. Frequent dressing changes, household cleaning along with the use of sprays were the most frequently used tactics to manage odour none of which were deemed to be very effective. CONCLUSION: This study highlights the problem of odour management in clinical practice and how individuals develop strategies to overcome odour. Sadly, patients were resigned to living with wound odour and were accepting of it as part of daily life. This highlights the importance for healthcare professionals to recognise, assess for and ensure a better understanding of how people experience wound odour, the impact it can have on them personally. Frequent dressing changes can help manage wound odour from the patient's perspective.

Systematic review of topical interventions for the management of odour in patients with chronic or malignant fungating wounds.

Chronic wounds adversely affect the quality of life of individuals and odour is a well-recognised associated factor. Odour can affect sleep, well-being, social interactions, diet and potentially wound healing. This systematic review aims to examine the effectiveness of topical interventions in the management of odour associated with chronic and malignant fungating wounds. A systematic review guided by PRISMA recommendations of randomised controlled trials where odour intensity/odour is the primary outcome was undertaken. Inclusion criteria were adults (18 years and over) with chronic venous, arterial, diabetic or pressure ulcers or with malignant fungating wounds where odour has been managed through topical application of pharmacological/non-pharmacological agents. Searches were conducted in CENTRAL, CINAHL, EMBASE, MEDLINE, Scopus, and Web of Science. Eligibility screening, risk of bias assessment and data extraction was completed by authors working independently. Searches retrieved 171 titles and abstracts (157 post de-duplication). Thirteen studies were retained for full text review of which five (n = 137 individuals) examining the following treatments remained: metronidazole (n = 4), silver (n = 1). Meta-analysis was not possible but individual studies suggest improved outcomes (i.e., reduced odour) using metronidazole. Treatment options to manage wound odour are limited and hampered by lack of clinical trials, small sample sizes, and absence of standardised outcomes and consistent measurement. Whereas metronidazole and silver may have a role in controlling wound odour, robust and well-designed interventions with rigorous procedures and standardised odour outcomes are necessary to evaluate their contribution.

Prevalence and incidence of venous leg ulcers-a protocol for a systematic review.

BACKGROUND: Venous leg ulcers (VLUs) are chronic wounds characterized by slow healing and high recurrence. Information on prevalence and incidence is essential for ascertaining the burden of VLU on the health care system and to inform epidemiological research, priority setting, and health care planning. The objective of this protocol is to present a transparent process for how we plan to review the existing international literature on the prevalence and incidence of VLU as well as the characteristics of the population reported within these studies. METHODS: An exploratory search was performed using MEDLINE via PubMed and CINHAL via Ebsco to identify concepts, keywords, MeSH terms, and headings to identify study types looking at data of VLU prevalence and/or incidence and related patient characteristics. The findings of this exploratory search will determine the final search strategy. The titles and abstracts of the identified articles will be screened independently be two authors for relevance. Study which pass the quality assessment will be included. Data extraction will be performed independently by two authors and in accordance with a pre-designed data extraction form. If the data allows, a meta-analysis will be performed otherwise a descriptive summary of the findings will be conducted. DISCUSSION: The results of this review will contribute to the evidence base on VLU occurrence and may inform the decision making of healthcare professionals, policy-makers, and consumers. It will also inform future research in this area of VLU care. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020205855.

The profile of patients with venous leg ulcers: A systematic review and global perspective.

BACKGROUND: A holistic profile that includes demographic, medical history and wound characteristics of individuals with venous leg ulceration is lacking. Lack of such a profile negatively impacts the ability to develop interventions to improve patient outcomes. OBJECTIVES: To describe the profile of the patient population with venous leg ulceration from published observational (non-interventional) studies and to identify gaps in the knowledge base for future research in this area. METHODS: A systematic review of observational studies that included more than 50 patients, from any world region, of any age and in any care setting. RESULTS: twenty studies, involving 3395 patients, from all world regions met our criteria. Demographic characteristics were well reported and showed a female to male ratio of 1.2:1, average age of 47-65 years, high levels of co-morbidities including hypertension (53-71%) and diabetes (16-20%), and only one study reporting ethnicity. When reported, approximately 4-30% had high levels of depression. The average wound size was 18.6-43.39 cm2; mean wound duration was 13.8-65.5 months, mean number of recurrences was four. No study reported on demographic factors plus medical history plus wound characteristics together. CONCLUSION: a comprehensive, holistic profile of the population with VLU is lacking. There is a critical need for more comprehensive profiling to enable the development of targeted interventions to improve outcomes.

Randomized controlled trial of honey versus mupirocin to decolonize patients with nasal colonization of meticillin-resistant Staphylococcus aureus.

BACKGROUND: Mupirocin is used specifically for the eradication of nasal meticillin-resistant Staphylococcus aureus (MRSA), but increasing mupirocin resistance restricts its repeated use. The antibacterial effects of manuka honey have been established in vitro; antibacterial activity of other honeys has also been reported. AIM: To describe the learning experience from a randomized controlled trial (RCT) comparing the efficacy of medical-grade honey (MGH) with mupirocin 2% for the eradication of nasal MRSA. METHODS: Patients colonized in the nose with MRSA and age ≥18 years were recruited. Participants received either one or two courses of MGH or mupirocin 2%, three times per day for five consecutive days. FINDINGS: The proportion of patients who were decolonized after one or two courses of treatment was not significantly different between MGH [18/42; 42.8%; 95% confidence interval (CI): 27.7-59.0] and mupirocin 2% (25/44; 56.8%; 95% CI: 41.0-71.7). Non-nasal MRSA colonization was significantly associated with persistent nasal colonization (odds ratio: 5.186; 95% CI: 1.736-5.489; P = 0.003). The rate of new acquisition of mupirocin resistance was 9.75%. CONCLUSION: Although not significant, a decolonization rate of 42.8% for MGH was impressive. Our findings suggest that this strategy, which has the potential to combat antimicrobial resistance, should be assessed in similar but larger studies.

Mupirocin resistance: clinical implications and potential alternatives for the eradication of MRSA.

Mupirocin 2% ointment is used either alone or with skin antiseptics as part of a comprehensive MRSA decolonization strategy. Increased mupirocin use predisposes to mupirocin resistance, which is significantly associated with persistent MRSA carriage. Mupirocin resistance as high as 81% has been reported. There is a strong association between previous mupirocin exposure and both low-level and high-level mupirocin resistance. High-level mupirocin resistance (mupA carriage) is also linked to MDR. Among MRSA isolates, the presence of the qacA and/or qacB gene, encoding resistance to chlorhexidine, ranges from 65% to 91%, which, along with mupirocin resistance, is associated with failed decolonization. This is of significant concern for patient care and infection prevention and control strategies as both these agents are used concurrently for decolonization. Increasing bacterial resistance necessitates the discovery or development of new antimicrobial therapies. These include, for example, polyhexanide, lysostaphin, ethanol, omiganan pentahydrochloride, tea tree oil, probiotics, bacteriophages and honey. However, few of these have been evaluated fully or extensively tested in clinical trials and this is required to in part address the implications of mupirocin resistance.

Heterogeneity of wound outcome measures in RCTs of treatments for VLUs: a systematic review.

OBJECTIVE: Venous leg ulcers (VLUs) affect up to 4% of the population aged over 65 years. Outcomes of randomised controlled trials (RCTs) in VLUs are important to guide clinical and resource decision making. Our objective was to identify what endpoints and wound bed outcomes were assessed in RCTs in VLUs; how these were assessed and what reference was made to validity and reliability of methods used. METHOD: A systematic review of all full text RCTs, published in English, from 1998-2013. RESULTS: Our criteria were met by 102 studies. There were 78 different endpoints recorded, the majority (n=34) related to healing and were evaluated at 12 different times points. Size was the most frequently reported outcome measure (n=99), with photographs, tissue type, exudate, odour and pain also recorded. There was poor reporting of methods used to assess outcomes. Visual analogue scales predominated as a method of assessment, but 95% of studies made no reference to the validity or reliability of assessment methods. CONCLUSION: Future research in VLUs requires standards for measuring outcomes with acceptable inter-rater reliability and validated measures of patient-reported outcomes.

Elective surgery: a comparison of in-patient versus day surgery practices in Ireland.

BACKGROUND: Currently, there is a paucity of research which has assessed practices at the point of care for day surgery patient. AIM: To outline the patient journey from first referral for surgery and identify structures and processes which facilitate or constrain the provision of day surgery. METHOD: A retrospective medical charts review of 200 consecutively presenting patients undergoing elective surgery in two Irish teaching hospitals. Data collection was completed from January 2009 to March 2009. This analysis spanned from first referral to the hospital until discharge and follow up. RESULTS: Great variability was noted in practices between the two hospitals. While some of the differences in practice become barriers to increased rates of day surgery, others did not have an impact. CONCLUSION: This study echoes findings of other similar studies in that management of patients undergoing elective surgery which varies significantly across Irish hospitals.

The dissemination of wound management guidelines: a national survey.

OBJECTIVE: In 2009, the Health Service Executive (Ireland) launched the first national guidelines for wound management. The Wound Management Association of Ireland (WMAI) participated in their development and dissemination. This study aimed to determine how aware of the guidelines members of the WMAI were, how they became aware of them, and if they had disseminated them further. METHOD: 130 members of the WMAI were surveyed. The questionnaire was developed using previous questionnaires assessing dissemination as a reference and was reviewed by the executive panel for face and construct validity. RESULTS: The response rate was 55% (72/130). Fifty-seven per cent (n=41) had attended education sessions in which the guidelines were on the agenda. These included WMAI local events (43%), work events (16%), industry sponsored events (10%) and college course (7%). Fifty-one per cent had heard about the guidelines from the WMAI national conference. Eighty-five per cent had informed others of the guidelines, 70% had given a copy to others. Seventeen per cent (n=12) had given a presentation about the guidelines. Of these, five had given one presentation; two had given four and two had given five. Seventy-five per cent of which were at work. Currently, 56% of people are working on implementation. While full-text, 'hard' copies were not printed, people still requested these and 47% downloaded the full-text for their own use. CONCLUSION: Clinical practice guidelines are vital for the provision of evidence based health care. However, they are ineffective unless disseminated and implemented. Wound care organisations are able to play a key role in dissemination and feedback from this survey suggests that this has been achieved.

National survey of the provision of day surgery across public and private hospitals in Ireland.

BACKGROUND: Day surgery (DS) is viewed as the optimal environment for many surgical procedures. Yet, Irish DS rates are low compared to international figures. AIMS: To describe the current provision of DS in Ireland and to identify barriers to its expansion. METHODS: Thirty-seven public hospitals and 17 private hospitals providing DS were surveyed during July/August 2009. RESULTS: Thirty-seven hospitals replied (67%) (30 public, 7 private). DS beds ranged from 3 to 39. Fourteen (38%) had dedicated DS units, and no unit had a consultant in charge. Twenty-one (57%) provided pre-assessment with 36 (96%) providing patient information leaflets both pre- and post-operatively. Stay-in rate was less than 5%. Eight units had reviewed the adverse event rates following DS. Seven barriers to optimizing DS were identified, the main one being lack of dedicated DS theatres.

Can 'search and destroy' reduce nosocomial methicillin-resistant Staphylococcus aureus in an Irish hospital?

In Ireland, the Department of Health and Children recommends admission screening of patients at increased risk of methicillin-resistant Staphylococcus aureus (MRSA), isolation of these patients until proven negative, and eradication of any MRSA identified. These actions form the basis of a programme called 'search and destroy' that has successfully reduced MRSA in Scandinavia. There is, however, very little information published on the use of search and destroy in Ireland. This study was carried out using a quantitative, quasi-experimental design in the form of an interventional cohort study. The effect of reducing the turnaround time for MRSA results (2007) and the introduction of pre-emptive isolation (2008) was examined in a hospital with an established admission screening programme for MRSA. Rates of MRSA infection and colonisation were monitored post-intervention and compared to baseline rates prior to the intervention (2005-2006). Rates of hospital-acquired (nosocomial) MRSA infections and colonisation fell in both 2007 and 2008. However, due to the quasi-experimental design of the study and the low endemic level of MRSA in the hospital, a causal link could not be established.

Prevalence of wounds in a community care setting in Ireland.

OBJECTIVE: To establish the prevalence of wounds and their management in a community care setting. METHOD: A multi-site, census point prevalence wound survey was conducted in the following areas: intellectual disability, psychiatry, GP practices, prisons, long-term care private nursing homes, long-term care, public nursing homes and the community/public health (district) nursing services on one randomly selected day. Acute services were excluded. Formal ethical approval was obtained. Data were collected using a pre-piloted questionnaire. Education was provided to nurses recording the tool (n=148). Descriptive statistical analysis was performed. RESULTS: A 97.2% response rate yielded a crude prevalence rate of 15.6% for wounds across nursing disciplines (290/1,854 total census) and 0.2% for the community area (290/133,562 population statistics for the study area). Crude point prevalence ranged from 2.7% in the prison services (7/262 total prison population surveyed) to 33.5% in the intellectual disability services (72/215 total intellectual disability population surveyed). The most frequent wounds recorded were pressure ulcers (crude point prevalence 4%, 76/1,854 total census; excluding category l crude point prevalence was 2.6%, 49/1,854 total census), leg ulcers (crude point prevalence 2.9%, 55/1,854 total census), self-inflicted superficial abrasions (crude point prevalence 2.2%, 41/1,854 total census) and surgical wounds (crude point prevalence 1.7%, 32/1,854 total census). CONCLUSION: These results support previous international research in that they identify a high prevalence of wounds in the community. The true community prevalence of wounds is arguably much higher, as this study identified only wounds known to the nursing services and excluded acute settings and was conducted on one day.

Bacteriological changes in sloughy venous leg ulcers treated with manuka honey or hydrogel: an RCT.

OBJECTIVE: To determine the qualitative bacteriological changes that occurred during a four-week treatment period with either manuka honey or a hydrogel dressing. This was the secondary outcome of a randomised controlled trial (RCT) that compared the efficacy of the two treatments in desloughing venous leg ulcers. METHOD: This was a prospective open label multicentre RCT with blinded microbiological outcome analysis. Randomisation was conducted via remote telephone. To be included, the wound bed needed to comprise at least 50% slough. Wound swabs were taken at the start of treatment and after four weeks. RESULTS: In all, 108 patients (35 males, 73 females) aged 24-89 years (mean 68) enrolled into the study. Both groups were comparable at baseline. Eighteen patients (17%) were withdrawn due to a wound infection: six in the honey group and 12 in the hydrogel group. Staphylococcus aureus was the most common isolate, being identified in 41 wounds (38%). At baseline, meticillin-resistant Staphylococcus aureus was identified in 16 wounds (10 honey versus six hydrogel). After four weeks 70% (n=7) of the manuka-honey treated wounds versus 16% (n=1) of the hydrogel treated wounds had MRSA eradicated. Pseudomonas aeruginosa was reported in 14% (n=16) of all wounds at baseline. After four weeks 33% (n=2) treated with honey and 50% (n=5) treated with hydrogel had this eliminated. The number of wounds (n=11 at baseline; n=15 at week 4) with > or =3 bacteria species remained constant over the four weeks. CONCLUSION: Manuka honey was effective in eradicating MRSA from 70% of chronic venous ulcers. The potential to prevent infection is increased when wounds are desloughed and MRSA is eliminated. This can be beneficial to prevent cross-infection.

Estimating costs of pressure area management based on a survey of ulcer care in one Irish hospital.

OBJECTIVE: Pressure ulceration remains a significant cause of morbidity for patients and has a real economic impact on the health sector. Studies to date have estimated the cost of management but have not always given a breakdown of how these figures were calculated. There are no published studies that have estimated the cost of management of pressure ulcers in Ireland. A two-part study was therefore undertaken. Part one determined the prevalence of pressure ulcers in a 626-bed Irish acute hospital. Part two set out to derive a best estimate of the cost of managing pressure ulcers in Ireland. METHOD: The European Pressure UlcerAdvisory Panel (EPUAP) minimum data set tool was used to complete the prevalence survey. Tissue viability nurses trained in the data-collection tool collected the data. A cost was obtained for all items of care for the management of one patient with three grade IV pressure ulcers over a five-month period. RESULTS: Of the patients, 2.5% had pressure ulcers. It cost Euros 119,000 to successfully treat one patient. CONCLUSION: We estimate that it costs Euros 250,000,000 per annum to manage pressure ulcers across all care settings in Ireland.
