Comparative Study of the Efficacy of EHO-85, a Hydrogel Containing Olive Tree (Olea europaea) Leaf Extract, in Skin Wound Healing.

Olive tree (Olea europaea) leaf extract (OELE) has important antioxidant and anti-inflammatory properties, supporting its use in human clinical practice. We recently designed an amorphous hydrogel called EHO-85 (EHO indicates olive leaf extract in Spanish) containing OELE for skin ulcer treatments. Yet, its effectiveness has not been previously compared with other products used in routine clinical practice. This is necessary to evaluate its potential translation to the human clinic. Thus, in this study, the effect of EHO-85 on healing was evaluated in comparison with treatments containing Indian/Asiatic pennywort (Centella asiatica), hyaluronic acid, or dexpanthenol in a rat model. The speed of wound closure and histological parameters after seven and 14 days were analyzed. All treatments accelerated wound closure, but there were differences between them. Dexpanthenol after seven days produced the highest epithelialization and the lowest inflammation and vascularization. EHO-85 also promoted epithelialization and reduced vascularization. After 14 days, wounds treated with EHO-85 showed less inflammation and higher levels of collagen in the extracellular matrix. This indicates a higher degree of maturity in the regenerated tissue. In conclusion, the effect of EHO-85 on healing was equal to or superior to that of other treatments routinely used in human clinical practice. Therefore, these results, together with previous data on the effects of this hydrogel on ulcer healing in humans, indicate that EHO-85 is a suitable, low-cost, and efficient therapeutic option for wound healing.

Trends in mortality due to pressure ulcers in Spain, over the period 1999-2016.

AIM: to analyse trends in mortality by Pressure Ulcers (PU) in Spain, between 1999 and 2016. METHODS: Mortality due to PU in residents in Spain over 65, where a PU was underlying/basic cause of death, was analysed. Data for populations and deaths were gathered from the Spanish National Statistics Institute. Variables were age, sex, year of death and underlying/basic cause of death. Age-adjusted mortality rates were calculated (direct method), with 2013 European standard population. To analyse temporal trends and to detect significant changes, joinpoint regression models were adjusted to estimate average annual percentage change of Age-Adjusted mortality Rates for each segment detected. An analysis was performed for those over 65, and by the age groups 65-84, and over 84 years. RESULTS: A total of 11,238 deaths due to PU in people over 65, between 1999 and 2016, were analysed. There was a general decrease for both, women and men, over the period. From the Joinpoint analysis, for men, two changes were detected in those over 65, with a significant decrease observed until 2008. For those over 84, was a significant decrease of 4.4% on average per year. For women, a significant decrease is observed in all age groups, with a change of trend in 2007. CONCLUSION: This study provides a general overview of the epidemiology of PU mortality in Spain. It may serve as a confirmation of the good health policies carried out in the past on PU, given that we observe a generalised decrease in mortality from PUs over the period. Mortality was higher in women at the beginning of the period but without differences at the end, compared with men. Changes occurred over time could be explained by implementation of patient safety policies.

Prevalence and characteristics of older people with pressure ulcers and legs ulcers, in nursing homes in Barcelona.

BACKGROUND: Nursing home residents are vulnerable to chronic wounds. However, the prevalence data are scarce. AIM: The purpose of this study was to determine the prevalence of pressure ulcers and/or leg ulcers in nursing home residents, and describe the characteristics of the nursing homes, the residents and the wounds, as well as possible associations between these characteristics. METHODS: This was a cross-sectional survey of nursing home residents over the age of 65 in 168 facilities in Barcelona. Those presenting category II-IV pressure ulcers and/or leg ulcers were included. The data were collected by observation/examination. Descriptive, bivariate, and multivariate analyses were performed. RESULTS: The overall prevalence of pressure ulcers and leg ulcers combined was 4.4% (3.5% were pressure ulcers and 0.9% were leg ulcers). In small nursing homes with less nursing staff, the overall prevalence was greater than in large nursing homes (5.6% vs 3.8% [p = 0.01]). As expected, residents with pressure ulcers had higher pressure ulcer risk, worse dependence and cognitive status, urinary and faecal incontinence, and most were underweight. However, residents with leg ulcers had worse venous and arterial impairment and also were overweight. A multivariate analysis showed that pressure ulcers were statistically significantly associated with faecal incontinence (OR = 0.28, 95% CI = 0.09-0.81) and dyslipidaemia (OR = 0.21, 95% CI = 0.06-0.66), and leg ulcers were statistically significantly associated with venous insufficiency (OR = 4.93, 95% CI = 1.65-15.34). The characteristics of gluteal and ischial pressure ulcers, a high prevalence of infection, and a low reference to biofilm by nurses, in both types of wounds, suggest that these aspects are not adequately taken into account. CONCLUSIONS: Pressure ulcers and leg ulcers, mainly pressure ulcers, remain a public health problem in nursing homes. Further studies are required to confirm the associations found in this study.

Specialised wound care clinics in Spain: distribution and characteristics.

OBJECTIVE: To determine the number of specialised wound care units/clinics (SWCUs) in Spain, at present, and to describe their most important characteristics. METHOD: This was an observational study with a descriptive-analytical, cross-sectional, multicentre approach, where the studied population consisted of SWCUs in Spain. A specific data-collection questionnaire was designed using a modified Delphi method, consisting of four rounds, with the collaboration of 10 wound experts. The final questionnaire included 49 items distributed across four dimensions/areas with a content validity index (CVI-Total for pertinence=0.96 and CVI-Total for relevance=0.94. RESULTS: A total of 42 SWCUs were included in the study. Most SWCUs were based in hospitals (n=15, 35.7%) or healthcare centres, covering a specific healthcare area (n=17, 40.5%). SWCU coordinators were primarily nurses (n=33, 78.6%). Staff members' professions in SWCUs included registered nurses (n=38 units, 92.7%), nursing assistants (n=8 units, 19.5%), podiatrists (n=8 units, 19.5%), vascular surgeons (n=7 units, 17%), osteopaths (n=2 units, 4.8%) and medical doctors from different specialties (n=3 units, 7.2%). For wound aetiology, the most prevalent wounds managed were diabetic foot ulcers (n=38 units, 90.5%), followed by venous leg ulcers (n=36 units, 85.7%) and arterial ischaemic ulcers (n=36 units, 85.7%). A statistically significant association was found between the number of staff members in a SWCU and the existence of resistance/opposition barriers when developing a SWCU (Chi-square test, p=0.049; Cramér's V=0.34; 34%), as well as between resistance/opposition barriers when developing a SWCU and a nurse as coordinator of a SWCU (MacNemar test, p=0.007, Cramér's V=0.35; 35%). CONCLUSION: The typical SWCU implemented in Spain is located in a hospital or integrated in a healthcare structure that offers coverage to a whole health area and providing services for people with hard-to-heal wounds (wound management and prevention) and health professionals (advice, consultancy and training/education). Despite the growing number of SWCUs in Spain, the future of this new organisational model is uncertain, as there can be barriers to creating them and some deficiencies, such as low staff numbers, which need to be addressed.

Epidemiology of venous leg ulcers in primary health care: Incidence and prevalence in a health centre-A time series study (2010-2014).

The aims of the study were to describe and analyse the temporal trend of the prevalence and incidence of venous leg ulcers (VLU) over the years 2010 to 2014, to determine healing times and temporal trends in the study period, and to evaluate related aspects such as the use of the Ankle-Brachial Pressure Index (ABPI) in a primary care health centre. This was a retrospective study based on a time series (years 2010-2014) of the prevalence and incidence of VLUs in people aged over 40 years in a primary care centre in Barcelona City. We reviewed 3920 electronic health records selecting patients, per year (2010-2014), with VLUs based on the ICD-10 diagnoses. For prevalence, we took into account any patient with an active VLU in the year of study. For incidence, we took into account patients with a new VLU in the year of study. A descriptive analysis was carried out based on each of the collected variables. The variables were examined according to the years of study (time series) by one-factor analysis of variance (anova) or Kruskal-Wallis non-parametric test, as appropriate. A survival analysis by Kaplan-Meier curves and log-rank test was also performed. A total of 139 patients met the VLU criteria. Among them, only 79.2% were classified as having a VLU and had a correct ICD diagnosis. The prevalence and incidence increased over the years, doubling in patients aged over 65 years. Incidence increased from 0.5 new cases per 1000 people/year in 2010 to 1 new case for every 1000 people/year in 2014. Moreover, the prevalence ranged between 0.8 and 2.2 patients with VLU for every 1000 people/year. During the study period, a total of 84.2% of the VLUs healed (117/139 VLU). Regarding average annual time to healing, the trend indicates that lesions took less time to heal (Kruskal-Wallis test, P = 0.004), ranging between 453,9 weeks in 2005 to 19 weeks in 2014. The use of ABPI also evolved and was found to be increasingly performed prior to the appearance of the lesion. The epidemiological profile of people affected by VLUs continues to be, mainly, that of women of an advanced age, over 70 years. The frequency of VLU occurrence rose continually over the years, but healing took less time, and use of ABPI improved. Assigning a reference nurse in the wounds unit and the organisational structure around this problem may have an influence on improving care and the approach to these types of lesions.

Content, implementation strategies and knowledge assessment tool on venous leg ulcers: An e-Delphi study.

AIM: To get consensus on the knowledge and skills that nursing students need to acquire regarding venous leg ulcer care, the strategies that can be applied during education and to design a first draft of a questionnaire to assess knowledge to be validated. BACKGROUND: Venous leg ulcers' care is included on undergraduate nursing education programmes but without specifying the content and training implementation strategies. Different tools have been validated to assess knowledge, but have been found inadequate. DESIGN: An e-Delphi study. METHODS: The participants were Chronic Wound Care expert nurses. Two questions were constructed and agreed on by the research team to define the problem. To answer the third question, a search was conducted for publications on venous leg ulcers, to help design the questionnaire. A 2-round e-Delphi study was conducted from January to March 2022. A panel of 17 experts participated in both rounds. The data were analysed using statistical and qualitative analysis. RESULTS: Content must fulfil knowledge-skill areas: epidemiology, venous pathophysiology and aetiology, classification scales, knowing how to determine a differential diagnosis, treatment, measures for prevention and care of the venous return circuit, quality-of-life scales. As implementation strategies, proposals were made in four areas: subject profile where training is to be acquired, theoretical teaching, practical teaching in the classroom and clinical practice. The average consensus of the questionnaire proposal was high (>86 %) both in relevance and clarity in both rounds. We thereby obtained a questionnaire with 72 items. CONCLUSIONS: Seven categories and eight subcategories were created regarding knowledge/skills that nursing students should acquire. Four categories were recognised as strategies that can be implemented during education. A high level of consensus was reached on the items in the initial versions of the questionnaire.

Cross-Cultural Adaptation and Validation of the Perceptions of Empowerment in Midwifery Scale in the Spanish Context (PEMS-e).

Midwifery empowerment is an important topic. The most widely used instrument to measure the perceived empowerment of midwives is the Perceptions of Empowerment in Midwifery Scale (PEMS), which has not been validated in Spain. The aim of this study was to translate and adapt the PEMS to the Spanish context. This research was carried out in two phases; Phase 1: Methodological study; translation, backtranslation and cross-cultural adaptation of the PEMS and pilot study on the target population (10 midwives) for evaluation of face validity. Phase 2: Cross-sectional observational study to obtain a sample for construct validation by Exploratory Factor Analysis and measurement of PEMS-e reliability. Additionally, an inferential analysis was carried out to study the possible association between several collected variables and PEMS-e subscale-scores. A total of 410 midwives from 18 Spanish regions participated in the study through an online questionnaire. An initial Spanish version of the PEMS scale was produced, demonstrating adequate face validity. A final model was produced for the PEMS-e, which included 17 items classified into two subscales ("Organizational support" and "Own skills and teamwork") with fit indexes RMSEA = 0.062 (95%CI: 0.048-0.065) and AGFI = 0.985 (95%CI: 0.983-0.989) and Cronbach's alpha 0.922 for the total scale. Results showed that one in four midwives had considered abandoning the profession in the last 6 months (p ≤ 0.001). This research suggests that Spanish midwives perceive their empowerment level as low. The PEMS-e is a valid tool with solid psychometric properties that can be used in future research to identify factors that contribute to increased empowerment among Spanish midwives and inform strategies to improve job satisfaction and retention in the profession.

EHO-85, Novel Amorphous Antioxidant Hydrogel, Containing Olea europaea Leaf Extract-Rheological Properties, and Superiority over a Standard Hydrogel in Accelerating Early Wound Healing: A Randomized Controlled Trial.

Many advanced wound healing dressings exist, but there is little high-quality evidence to support them. To determine the performance of a novel amorphous hydrogel (EHO-85) in relation to its application, we compared its rheological properties with those of other standard hydrogels (SH), and we assessed the induction of acceleration of the early stages of wound healing as a secondary objective of a prospective, multicenter, randomized, observer-blinded, controlled trial. The patients were recruited if they had pressure, venous, or diabetic foot ulcers and were treated with EHO-85 (n = 103) or VariHesive® (SH) (n = 92), and their response was assessed by intention-to-treat as wound area reduction (WAR (%)) and healing rate (HR mm2/day) in the second and fourth weeks of treatment. Results: EHO-85 had the highest shear thinning and G'/G″ ratio, the lowest viscous modulus, G″, and relatively low cohesive energy; EHO-85 had a significantly superior effect over SH in WAR and HR, accelerating wound healing in the second and fourth weeks of application (p: 0.002). This superiority is likely based on its optimal moisturizing capacity and excellent pH-lowering and antioxidant properties. In addition, the distinct shear thinning of EHO-85 facilitates spreading by gentle hand pressure, making it easier to apply to wounds. These rheological properties contribute to its improved performance.

Knowledge and teaching-learning methods regarding venous leg ulcers in nursing professionals and students: A scoping review.

AIM: According to our scoping review questions, three aims were formulated to synthesize the evidence published on: (1) the content (2) the best or most appropriate teaching-learning methods for training nurses and undergraduate nursing students in venous leg ulcer care, and (3) to identify the level of knowledge in nurses and undergraduate nursing students about venous leg ulcer care. BACKGROUND: A venous leg ulcer can be defined as a skin lesion on the leg or foot that occurs in an area affected by ambulatory venous hypertension. Hence, nurse visits are the main driver of Venous Leg Ulcer-related healthcare costs. Optimal levels of knowledge obtained with appropriate methodologies tend to improve care. Nonetheless, the time devoted to chronic wound education in undergraduate nursing curricula has been considered insufficient and inadequate. METHODS: For this scoping review, a search was performed in January 2021. To identify sources of evidence, a systematic search was conducted in MEDLINE, Embase, CINAHL, Web of Science, Scopus, Cuiden, ERIC and ScienceDirect. All types of evidence associated with knowledge, teaching and/or learning methods regarding venous leg ulcers in nursing were included. RESULTS: Finally, 19 documents were included. In these articles, the content mostly widely included in teaching-learning methods was compression therapy (14/19), anatomy, physiology, aetiology and/or pathophysiology (10/19) and topical treatment and care (8/19); various other topics were mentioned but less frequently. Teaching/learning methods and interventions were heterogeneous in modality, content, and duration but the majority showed better results after implementation. When looking at knowledge level, studies mainly focused on nursing staff. In general, it seems that there is a lack of knowledge and skills. CONCLUSIONS: Regarding our three pivotal questions: (1) There is no uniform type of content over the studies analysed and the most referred was compression therapy. (2) The educational interventions studied have demonstrated effectiveness, but there is insufficient data to determine which is the most effective. (3) This scoping review has highlighted the lack of knowledge among nurses and nursing students about venous leg ulcer care. Additionally, we felt that there is no ideal assessment tool to quantify knowledge, skills, attitude, confidence, and commitment in this context. TWEETABLE ABSTRACT: A scoping review that synthesise the evidence on the level of knowledge and teaching-learning methods in nursing regarding of people with venous leg ulcers shows lack of knowledge and variability in programs.

Feelings of being a second victim among Spanish midwives and obstetricians.

AIM: The aim of this study was to determine the prevalence of feelings of being a second victim among midwives and obstetricians in Spain and to explore possible differences between the two professions. DESIGN: Cross-sectional descriptive-analytical observational study. METHODS: An online survey collecting several variables was administered throughout the Spanish territory. Spanish version of the Second Victim Experience and Support Tool (SVEST) was used. The data collection period was from May to December 2020. RESULTS: A total sample of 719 obstetricians and midwives were studied. There were significant differences between the two groups with respect to seven dimensions of SVEST: greater feelings of being a second victim among obstetricians in the dimensions physical distress/p ≤ .001, non-work-related support/p ≤ .001 and absenteeism/p ≤ .001 and greater feelings of being a second victim among midwives in the dimensions psychological distress/p ≤ .001, supervisor support/p = .011, professional self-efficacy/p ≤ .001 and intention to change jobs/p ≤ .001.

Validation and Psychometric Properties of the Spanish Version of the Fear of Childbirth Questionnaire (CFQ-e).

The fear of childbirth is a topical concern, yet the issue has barely been studied in Spain, and only one fear of childbirth measurement instrument has been validated in the country. The aim of this study was to translate, adapt and validate the Fear of Childbirth Questionnaire (CFQ) for use in Spain, as well as to describe and evaluate the psychometric properties of the Spanish version of this instrument. In a first phase, a methodological study was carried out (translation-backtranslation and cross-cultural adaptation), and pilot study was carried out in the target population. In addition, content validation of the instrument was obtained (CFQ-e) from 10 experts. In the second phase, a cross-sectional study was carried out at several centres in Gran Canaria Island to obtain a validation sample. The evaluation of the psychometric properties of the CFQ-e, including construct validity through exploratory factor analysis and confirmatory factor analysis, the calculation of reliability via factor consistency using the ORION coefficients as well as alpha and omega coefficients were carried out. The CFQ-e showed evidence of content validity, adequate construct validity and reliability. The CFQ-e is composed of 37 items distributed in four subscales or dimensions: "fear of medical interventions"; "fear of harm and dying"; "fear of pain" and "fears relating to sexual aspects and embarrassment". The CFQ-e constitutes a valid and reliable tool to measure the fear of childbirth in the Spanish pregnant population.

Superiority of a Novel Multifunctional Amorphous Hydrogel Containing Olea europaea Leaf Extract (EHO-85) for the Treatment of Skin Ulcers: A Randomized, Active-Controlled Clinical Trial.

This 8-week, multicenter, randomized, active-controlled, observer-blinded clinical trial was designed to demonstrate the accelerating effect on wound healing of the novel Olea europaea leaf extract hydrogel (EHO-85) by comparing it to a widely used amorphous hydrogel. Results showed that EHO-85 significantly accelerated wound healing, regardless of ulcer etiology (pressure, venous leg or diabetic foot) and prognosis, doubling the median wound area reduction compared with a reference amorphous hydrogel (79.4% vs. 39.7%; difference: −39.7%, 95% CI: −71.1 to −21.3%; p < 0.001). The intention-to-treat analysis was conducted on 195 patients from 23 Spanish health centers/nursing homes. This novel treatment balances the ulcer microenvironment by modulating reactive oxygen species and pH. These actions complement the moistening and barrier functions inherent to amorphous hydrogels, whilst also conferring EHO-85 its documented granulation formation and pain relief properties. Furthermore, efficacy was achieved safely and in a cost-efficient manner due to its multi-dose format, which reduced the amount of product needed by 85.8% over 8 weeks compared to single-use hydrogel. The present randomized controlled trial is a relevant milestone in evidence-based practice for being the first to demonstrate (i) the effectiveness of an amorphous hydrogel in accelerating wound healing and (ii) the superiority of a specific hydrogel over another.

Evaluation of Antioxidant and Wound-Healing Properties of EHO-85, a Novel Multifunctional Amorphous Hydrogel Containing Olea europaea Leaf Extract.

The excess of free radicals in the wound environment contributes to its stagnation during the inflammatory phase, favoring hard-to-heal wounds. Oxidative stress negatively affects cells and the extracellular matrix, hindering the healing process. In this study, we evaluated the antioxidant and wound-healing properties of a novel multifunctional amorphous hydrogel-containing Olea europaea leaf extract (OELE). Five assessments were performed: (i) phenolic compounds characterization in OELE; (ii) absolute antioxidant activity determination in OELE and hydrogel (EHO-85); (iii) antioxidant activity measurement of OELE and (iv) its protective effect on cell viability on human dermal fibroblasts (HDFs) and keratinocytes (HaCaT); and (v) EHO-85 wound-healing-capacity analysis on diabetic mice (db/db; BKS.Cg-m+/+Leprdb). The antioxidant activity of OELE was prominent: 2220, 1558, and 1969 µmol TE/g by DPPH, ABTS, and FRAP assays, respectively. Oxidative stress induced with H2O2 in HDFs and HaCaT was normalized, and their viability increased with OELE co-treatment, thus evidencing a protective role. EHO-85 produced an early and sustained wound-healing stimulating effect superior to controls in diabetic mice. This novel amorphous hydrogel presents an important ROS scavenger capacity due to the high phenolic content of OELE, which protects skin cells from oxidative stress and contributes to the physiological process of wound healing.

EHO-85: A Multifunctional Amorphous Hydrogel for Wound Healing Containing Olea europaea Leaf Extract: Effects on Wound Microenvironment and Preclinical Evaluation.

The prevalence of chronic wounds is increasing due to the population aging and associated pathologies, such as diabetes. These ulcers have an important socio-economic impact. Thus, it is necessary to design new products for their treatment with an adequate cost/effectiveness ratio. Among these products are amorphous hydrogels. Their composition can be manipulated to provide a favorable environment for ulcer healing. The aim of this study was to evaluate a novel multifunctional amorphous hydrogel (EHO-85), containing Olea europaea leaf extract, designed to enhance the wound healing process. For this purpose, its moistening ability, antioxidant capacity, effect on pH in the wound bed of experimental rats, and the effect on wound healing in a murine model of impaired wound healing were assessed. EHO-85 proved to be a remarkable moisturizer and its application in a rat skin wound model showed a significant antioxidant effect, decreasing lipid peroxidation in the wound bed. EHO-85 also decreased the pH of the ulcer bed from day 1. In addition, in mice (BKS. Cg-m +/+ Leprdb) EHO-85 treatment showed superior wound healing rates compared to hydrocolloid dressing. In conclusion, EHO-85 can speed up the closure of hard-to-heal wounds due to its multifunctional properties that are able to modulate the wound microenvironment, mainly through its remarkable effect on reactive oxygen species, pH, and moistening regulation.

Perceived satisfaction of women during labour at the Hospital Universitario Materno-Infantil of the Canary Islands through the Childbirth Experience Questionnaire (CEQ-E). / Satisfacción percibida por las mujeres durante el parto en el Hospital Universitario Materno-Infantil de Canarias a través del Childbirth Experience Questionnaire (CEQ-E).

OBJECTIVE: To determine the degree of satisfaction of women after childbirth at the Hospital Universitario Materno-Infantil of Gran Canaria (HUMIC) and to establish possible relationships between the degree of satisfaction and the variables studied. METHOD: A cross-sectional, descriptive, observational study with an analytical component. The study population comprised women who gave birth at the HUMIC in November 2018, recruited through consecutive non-probabilistic sampling. The Spanish version of the Childbirth Experience Questionnaire (CEQ-E) was used (questionnaire with 4 domains: own capacity', professional support, perceived safety and participation/analytical model 2). In a first phase a descriptive analysis was made, and in a second phase an inferential analysis to explore the association between different variables. RESULTS: The total sample comprised 257 women (n=257). The total score using the CEQ was 3.24 (SD .37 points). No statistically significant differences were found in the final CEQ score between the women who had a spontaneous delivery versus induction-stimulation (P=.563) or between primiparous versus multiparous women (P=.060). The women whose labour lasted 12hours or less (P=.024), without perineal trauma (P=.021) and those who had not undergone episiotomy (P=.002) achieved a better final CEQ score. Instrumental delivery (forceps) versus normal delivery is associated with lower scores with respect to the final CEQ-E score (P=≤.001). CONCLUSIONS: Women's overall satisfaction after delivery in HUMIC was high. Instrumental delivery seems to be associated with lower perceived satisfaction. Aspects such as fear and fatigue in labour could affect satisfaction negatively. These aspects can be improved by establishing strategies to increase comfort and minimise pregnant women's fear of labour.

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.

Diabetic foot self-care and concordance of 3diabetic foot risk stratification systems in a basic health area of Gran Canaria. / Nivel de autocuidados en pie diabético y concordancia de 3sistemas de estratificación de riesgo en una zona básica de salud de Gran Canaria.

OBJECTIVE: To assess the level of self-care in the population with diabetes and determine the risk of diabetic foot lesions through the use of 3stratification systems as well as to establish the degree of concordance between these systems. METHOD: Observational, cross-sectional and descriptive study carried out in the Basic Health Area of Santa Brígida (Gran Canaria-Canary Islands-Spain) in people diagnosed with diabetes (DM Type 1/DM Type 2) (n=182). Interview, physical examination, review of clinical history and completion of the Diabetic Foot Self-Care questionnaire of the University of Malaga were carried out. The risk stratification was then calculated using 3systems (System of the National Institute for Health Care Excellence, Classification of the International Working Group on the Diabetic Foot and High-Risk Diabetic Foot-60-Second Tool©-2012). The Kappa index was calculated to study the concordance between systems, the relative risk of negative screening of one method against another was estimated and the exact Fisher test to establish whether there were differences. RESULTS: 30.2% of diabetics had a low level of self-care, 45.1% a medium level and 24.7% a high level. The risk levels calculated were: National Institute for Health Care Excellence Classification (Negative Risk 71.4%-Positive Risk 28.6%), International Working Group on the Diabetic Foot Classification (Negative Risk 67.0%-Positive Risk 33.0%) and High-Risk Diabetic Foot-60-Second Tool© (Negative Risk 62.6%-Positive Risk 37.4%). CONCLUSIONS: All 3systems have good concordance with each other. The High-Risk Diabetic Foot-60-Second Tool© only distinguishes 2levels of risk but detects a higher percentage of people at risk. The Diabetic Foot Self-Care questionnaire of the University of Malaga may be useful in the context of Primary Care to assess the level of self-care of people with diabetes.
