Palliative Care in the Management of Pain, Odor, and Exudate in Chronic Wounds at the End of Life: A Cohort Study

Data Requirement for Animal-Derived Wound Care Devices: Limitations of the 510(k) Regulatory Pathway

BACKGROUND

Device classification and preclinical data requirements for animal-derived wound care products were recently reviewed by the FDA. Given the possible performance differences for these products, we evaluated the FDA data requirements as well as the published literature for all animal-derived wound care products ever cleared through the FDA.

STUDY DESIGN

The publicly available online database was queried for all animal-derived wound products; premarket data requirements for each product were recorded. A PubMed search was conducted to determine the number of published clinical studies for each product, and manufacturer websites were accessed to obtain the price for each product.

RESULTS

A total of 132 animal-derived wound products have been cleared by the FDA since the Center for Devices and Radiological Health was established in 1976. Of these, 114 had a publicly available clearance statement online. Preclinical biocompatibility testing was performed in 85 products (74.6%) and referenced in 10 (8.8%). Preclinical animal wound healing testing took place in 17 (14.9%). Only 9 products (7.9%) had clinical safety testing, and no products had clinical effectiveness data. We found no published peer-reviewed clinical data for 97 products (73%). Cost was infrequently available but ranged from $4.79 to $2,178 per unit.

CONCLUSIONS

Although the current pathway is appropriate for efficiently clearing new wound care products, clinical effectiveness is not included in the regulatory review process. Wound care products are primarily evaluated by the FDA for safety and biocompatibility. Thus, any claims of clinical effectiveness require independent validation, which is often lacking.

The Use of Medical Grade Honey on Infected Chronic Diabetic Foot Ulcers-A Prospective Case-Control Study

Non-healing wounds are usually colonised and contaminated by different types of bacteria. An alternative to antibiotic treatment in patients with infected wounds with local signs of inflammation may be medical grade honey (MGH). MGH has antioxidant, antimicrobial, anti-inflammatory, and immunomodulatory features. This study aims to evaluate the effect of MGH therapy on infected non-healing wounds, especially for diabetic foot syndrome. Prospective, observational case series (n = 5) of patients with wounds of diabetic foot syndrome are presented. There were five males with an average age of 61.6 years. All wounds were treated with MGH, and the healing trajectory was rigorously and objectively monitored. In all cases, there was a gradual disappearance of odour, pain, and exudation. Moreover, the wound areas significantly reduced within 40 days and there was a decrease in glycated haemoglobin and glycaemia values. All these outcomes resulted in improved quality of life of the patients. Despite bacterial colonisation, antibiotic treatment was not necessary. All wounds were completely healed. MGH has antimicrobial, anti-inflammatory, and antioxidant effects in diabetic foot syndrome wounds, does not increase glycated haemoglobin or glycaemia levels, and thus constitutes an effective alternative to the use of antibiotics in the treatment of locally infected wounds.

Interactive Evidence-Based Pressure Injury Education Program for Hospice Nursing: A Quality Improvement Approach

PURPOSE

The purpose of this quality improvement (QI) project was to develop and implement an interactive, evidence-based pressure injury (PI) education program and evaluate the impact on frontline hospice nursing staff knowledge and practice.

PARTICIPANTS AND SETTING

The QI setting was a 12-bed inpatient hospice unit in a tertiary care Veterans Affairs (VA) Medical Center in Cleveland, Ohio. Nineteen licensed and unlicensed hospice nursing staff participated in this pre-/postworkshop project.

APPROACH

Chart audit determined baseline PI incidence and prevalence on the inpatient hospice unit. Interviews with key leaders informed the need to develop and implement innovative PI education opportunities. A literature review determined existing standards regarding the benefits of PI education for nursing staff but did not reveal measurable targets in hospice settings. We developed a PI education intervention based on Kolcaba's Theory of Comfort framework and a Plan-Do-Study-Act (PDSA) performance improvement model. Education was delivered in 7 workshops, lasting 2 hours each. Knowledge, practice, and comfort for inpatient hospice nursing staff were evaluated at baseline and 8 weeks following the final refresher visit. Workshop satisfaction was collected once using standard program evaluation forms after final workshop delivery.

OUTCOMES

We observed a significant improvement in staff PI knowledge (P = .001) and practice (P = .001) after initial workshop attendance and repeat engagement (P = .001). There was a large magnitude of effect for overall knowledge change (d = 1.04); similarly PI care planning and practice showed a large magnitude of effect and significant improvement (P = .001, d = 2.64). Staff comfort with job duties was stable with low effect size (mean 4.52, d = 0.04), and satisfaction with the workshop education was high (100% agreement with trainer effectiveness).

IMPLICATIONS FOR PRACTICE

We found that frontline hospice nursing staff knowledge and practice improved after attendance at our evidence-based PI education program. Results of this QI project have stimulated ongoing discussion on how to sustain this program in our hospice setting.

Promoting and Maintaining Skin Integrity in End-of-Life Care: A Systematic Review

OBJECTIVE

To systematically review recommendations for promoting and maintaining skin integrity in end-of-life care and their level of evidence.

DATA SOURCES

MEDLINE (PubMed interface), CINAHL (Cumulative Index to Nursing and Allied Health Literature), EMBASE, and The Cochrane Library were systematically searched using a combination of key terms including end-of-life care, skin care, skin hygiene, and skin cleansing.

STUDY SELECTION

Articles were included if they (1) described skin care recommendations, including but not limited to the use of skin care products and interventions such as cleansing procedures; and (2) included adult patients who were expected to die within 12 months. There were no restrictions on study design, study setting, or language. Articles with a publication date before 2000 were excluded.

DATA EXTRACTION

Two data extraction forms were developed. The first included information about the author, publication year, type of evidence, study topic, sample, sample size, setting, limitations of the study, level of evidence, and quality of the study. The second included recommendations for promoting and maintaining skin integrity in patients at the end of life.

DATA SYNTHESIS

Because of methodological heterogeneity, results were synthesized narratively, and no meta-analysis was performed.

CONCLUSIONS

The information contained in the recommendations will assist nurses in promoting and maintaining skin integrity in patients at the end of life. More research is needed on end-of-life skin care, with an emphasis on patient-centered, holistic strategies that improve patient well-being and quality of life. In most current research, recommendations are limited to literature reviews and level V evidence. Skin care must balance the promotion and maintenance of skin integrity, wound prevention, and management while promoting patient dignity and quality of life.

How do wound care nurses structure the subjective frame on palliative wound care? A Q-methodology approach

Background

Palliative wound care is important for stability in terminal care. It addresses both the physical and psychological needs of patients and facilitates other aspects of terminal care. Appropriate competencies of nurses regarding palliative wound care can improve patient outcomes and raise their quality of life. The purpose of this study was to identify how wound care nurses structure the subjective frames regarding palliative wound care.

Method

This study utilized Q-methodology to analyze their subjective viewpoints. Forty nurses experienced in palliative wound care were asked to completely classify 35 Q-statements into a normal distribution shape. The PQ-Method program was used to conduct principal factor analysis and varimax rotation for data analysis.

Results

This study revealed 4 Q-factors of palliative wound care: “Focusing on care within the boundary of current patient demands,” “Comparing continuously the priorities on wound healing and disease care,” “Preparing and preventing from worsening via tracking care in advance,” and “Moving forward with a clear direction by confronting the declining condition.”

Conclusion

We hope that the results of this study are used in the development of nursing education that reflects professional perspectives of palliative wound care, thus helping to improve nursing competencies in palliative care.

Palliative Wound Care: Case Studies

Patients with advanced illness may present to palliative care or hospice with unmanaged symptoms that may be exacerbated by the presence of a wound. The wound can be a constant reminder to the patient and caregiver of the underlying illness. Distressing symptoms such as wound pain, odor, bleeding, and/or excessive exudate may impede the patients' ability to spend quality time with loved ones when they need them the most. Although patients may present with wounds of varying etiologies, the most common wounds seen in this patient population are pressure-related injuries. However, there is a shortage of both wound and palliative specialized clinicians. Telehealth and the use of other technology can be a way to address this shortage. This will grant access to a broader number of patients to ensure appropriate wound care plans are in place to meet the goals of care. Although wound healing may not always be possible in this patient population, having access to specialized wound and palliative experts can improve the quality of life for patients and their caregivers.

Medical-Grade Honey as an Alternative Treatment for Antibiotics in Non-Healing Wounds-A Prospective Case Series

Non-healing wounds are usually colonised by various types of bacteria. An alternative to antibiotic treatment in patients with infected wounds with local signs of inflammation may be medical-grade honey (MGH), which favourably affects the healing process with its antimicrobial, antioxidant, anti-inflammatory, and immunomodulatory properties. The objective of this study was to evaluate the effect of MGH therapy on the healing process of non-healing wounds of various aetiologies and different wound colonisations. Prospective, observation–intervention case studies (n = 9) of patients with wounds of various aetiologies (venous leg ulcers, diabetic foot ulcers, surgical wound dehiscence) are presented. All wounds were treated with MGH and the healing trajectory was rigorously and objectively monitored. In all cases, pain, odour, and exudation were quickly resolved, which led to an improvement in the quality of life of patients. Despite the proven bacterial microflora in wounds, antibiotic treatment was not necessary. The effects of MGH alleviated the signs of local infection until their complete elimination. In eight out of nine cases, the non-healing wound was completely healed. MGH has antimicrobial, anti-inflammatory, and antioxidant effects in wounds of various aetiologies and forms an effective alternative for the use of antibiotics for treating locally infected wounds.

Qualidade de vida de pessoas com feridas crônicas

Resumo Objetivo: Avaliar a qualidade de vida de pessoas com feridas crônicas. Métodos: Estudo transversal realizado com 176 pessoas com feridas crônicas em acompanhamento ambulatorial e domiciliar em um serviço público de saúde. Foram utilizados: formulário para a caracterização sociodemográfica, clínica e terapêutica e o questionário Cardiff Wound Impact Schedule para a mensuração da qualidade de vida. As análises foram descritivas e inferenciais empregando-se os testes t de Student, ANOVA, Mann Whitney e Kruskal-Wallis. Resultados: Dentre as pessoas acompanhadas em domicílio, predominaram lesões de origem vasculogênicas, com tempo de existência superior a 12 meses e área de até 25 cm2. No ambiente ambulatorial, prevaleceram feridas vasculogênicas e traumáticas, com tempo máximo de seis meses e extensão de até 25 cm2. Os fatores clínicos associados à qualidade de vida foram: tempo de duração da lesão, etiologia da lesão, grande extensão, aspecto do exsudato, presença de odor e de dor. O domínio de QV “bem-estar” apresentou maior impacto negativo decorrente da presença de lesão. Conclusão: Os fatores clínicos influenciaram diretamente os domínios de QV, sendo necessária a utilização de estratégias diferenciadas com o intuito de reduzir o impacto na QV por se tratarem de aspectos que poderiam ser atenuados ou evitados mediante a avaliação da lesão e a escolha do tratamento adequado.
