Modifiable patient-related factors associated with pressure ulcers on the sacrum and heels: Secondary data analyses

Improving the Use of Subscale-Specific Interventions of the Braden Scale Among Nurses

BACKGROUND

Pressure injuries (PIs) are costly to hospitals and have a negative impact on patient outcomes. Despite the use of validated tools that describe PI risk, such as the Braden Scale, the incidence of PIs remains high. Studies have shown that Braden Scale subscale scores should be considered when planning care; however, there is a discrepancy between understanding the importance of subscale-specific interventions and implementation. The goal of this study was to test the ability of an educational intervention tailored to specific interventions based on the subscales of the Braden Scale to improve knowledge among nurses.

METHOD

This study was a prospective, quasi-experimental, single-group design where nurses (n = 35) from a neurosurgery stepdown unit in a large teaching hospital completed a preintervention survey (T1), attended an educational presentation, and then completed an immediate postintervention survey (T2) and a 2-month postintervention survey (T3).

RESULTS

Data analysis compared presurvey scores with postsurvey scores. Nursing comprehension improved from the preintervention survey (T1, M = 5.57) to the postintervention surveys (T2, M = 6.34; T3, M = 6.42) (p = .031).

CONCLUSION

Nurses showed increased comprehension after the educational intervention from T1 to T3. [J Contin Educ Nurs. 2024;55(1):42-48.].

Impact of a new clinical mattress solution on interface pressure and comfort during supine lying

OBJECTIVE

Effective pressure management for individuals is critical for hospital and community-based care, to prevent the occurrence of pressure ulcers. This study explores the impact of a new mattress and topper solution on interface pressure and comfort during supine lying.

METHOD

In this quantitative, healthy cohort study, patient-surface interface pressures were calculated for three mattresses (a standard hospital mattress, a new mattress solution (Levitex Foams Ltd., UK) and a dynamic air flow mattress) with and without an innovative topper solution (Levitex Foams Ltd., UK). Subjective comfort, contact surface area, peak and mean pressure and peak pressure index (head, sacrum, heels) were calculated for all mattress conditions for a 21-minute period.

RESULTS

A total of 27 healthy volunteers took part in this study. The new mattress solution decreased peak pressure significantly compared with the hospital and air mattresses (p<0.04). Lower peak pressures were observed for the hospital mattress compared with the dynamic air flow mattress. The new mattress solution improved comfort and significantly lowered (>30%; p≤0.005) heel and head pressure compared with the other surfaces. Both hospital and air mattresses significantly reduced pressure and improved comfort with the addition of the new topper solution (p<0.05).

CONCLUSION

The new mattress solution used in this study offers a potentially improved pressure management solution for individuals. Implementation of the topper may also help to improve pressure management when used with existing standard or dynamic air flow mattresses.

Use of Medical-Grade Honey to Treat Clinically Infected Heel Pressure Ulcers in High-Risk Patients: A Prospective Case Series

Management of locally infected heel-pressure ulcers (HPUs) remains challenging, and given the increasing occurrence of infections resistant to antibiotic therapy and patients’ unwillingness to surgery, innovative and effective approaches must be considered. Medical-grade honey (MGH) could be an alternative therapeutic approach due to its broad-spectrum antimicrobial activity and healing properties. This study aimed to present the high effectiveness and safety of MGH for the conservative treatment of clinically infected HPUs. In this case series, we have prospectively studied nine patients with local signs of infected HPUs. In all cases, HPUs persisted for more than 4 weeks, and previous treatments with topical antibiotics or antiseptic products were ineffective. All patients were at high-risk to develop HPU infection due to their advanced age (median age of 86 years), several comorbidities, and permanent immobility. All wounds were treated with MGH products (L-Mesitran), leading to infection resolution within 3–4 weeks and complete wound healing without complication. Considering the failure of previous treatments and the chronic nature of the wounds, MGH was an effective treatment. MGH-based products are clinically and cost-effective for treating hard-to-heal pressure ulcers such as HPUs. Thus, MGH can be recommended as an alternative or complementary therapy in wound healing.

Graded stiffness offloading insoles better redistribute heel plantar pressure to protect the diabetic neuropathic foot

BACKGROUND

Diabetic heel ulceration is a common, detrimental, and costly complication of diabetes. This study investigates a novel "graded-stiffness" offloading method, which consists of a heel support with increasing levels of stiffness materials to better redistribute plantar pressure for heel ulcer prevention and treatment.

RESEARCH QUESTION

Is the novel "graded-stiffness" solution better able to redistribute heel pressure and reduce focal stress concentration areas of the heel?

METHODS

Twenty healthy young men walked with four, 3D-printed, insole configurations. The configurations included the "graded-stiffness" insoles with and without an offloading hole under the heel tissue at risk for ulcerations and two conventional offloading supports of flat insoles with no offloading and simple holed offloading insoles. In-shoe plantar pressure was measured using the Pedar-X system. Peak pressure and pressure dose were measured at three heel regions: offloaded region, perimeter of offloaded region, and periphery region.

RESULTS

The simple offloading configuration reduced pressure at the offloaded region; however, pressure at the perimeter of the offloading region significantly increased. With respect to ANOVA, the "graded-stiffness" offloading configurations were more effective than existing tested solutions in reducing and redistributing heel peak pressure and pressure dose, considering all heel regions.

SIGNIFICANCE

The "graded-stiffness" offloading solution demonstrated a novel flexible and customized solution that can be manufactured on-demand through a precise selection of the graded-stiffness offloading location and material properties to fit the shape and size of the ulcer. This study is a follow-up in-vivo pilot study, in a healthy population group, to our previous computation modeling work that reported the efficiency of the "graded-stiffness" configuration, and which emphasizes its potential for streamlining and optimizing the prevention and treatment of diabetic heel ulcers.

A novel graded-stiffness footwear device for heel ulcer prevention and treatment: a finite element-based study

Diabetic heel ulceration is a serious, destructive, and costly complication of diabetes. In this study, a novel "graded-stiffness" offloading method was proposed. This method consists of heel support with multi-increasing levels of stiffness materials, to prevent and treat heel ulcers. A three-dimensional finite element model of the heel was used to evaluate the novel "graded-stiffness" orthotic device compared to two existing solutions: (1) an insole with a hole under the active ulcer and (2) an insole with a hole filled with a soft material (elastic modulus of 15 kPa). Volumetric exposure evaluation of internal tissues to stress was performed at two volume-of-interests: (1) the area of the heel soft tissues typically at high risk for ulceration, and (2) the soft tissues surrounding the high-risk area. The models predict that the "graded-stiffness" offloading solution is more effective than existing solutions in distributing and reducing heel internal loads, considering both volume-of-interests. Comparing different material gradient combinations for the offloading support reveals considerable variation of the heel stress distribution. In clinical practice, the "graded-stiffness" technological solution enables to form an adaptable and flexible system that can be customized to a specific patient, through adequate selection of the offloading materials, to fit the shape and size of the ulcer. This solution can be made as an off-the-shelf product or alternatively, be manufactured by-demand using 3D printing tools. The proposed novel practical offloading solution has the potential for streamlining and optimizing the prevention and treatment of diabetic heel ulcers.

Risk factors associated with heel pressure ulcer development in adult population: A systematic literature review

AIMS

The main aim of this systematic literature review was to identify risk factors for development of heel pressure ulcers and quantify their effect.

BACKGROUND

Pressure ulcers remain one of the key patient safety challenges across all health care settings and heels are the second most common site for developing pressure ulcers after the sacrum.

DESIGN

Quantitative systematic review.

METHODS

Data sources: Electronic databases were searched for studies published between 1809 to March 2020 using keywords, Medical Subject Headings, and other index terms, as well as combinations of these terms and appropriate synonyms.

STUDY ELIGIBILITY CRITERIA

Previous systematic literature reviews, cohort, case control and cross-sectional studies investigating risk factors for developing heel pressure ulcers. Only articles published in English were reviewed with no restrictions on date of publication.

PARTICIPANTS

patients aged 18 years and above in any care setting. Study selection, data extraction, risk of bias and quality assessment were completed by two independent reviewers. Disagreements were resolved by discussion.

RESULTS

Thirteen studies met the eligibility criteria and several potential risk factors were identified. However, eligible studies were mainly moderate to low quality except for three high quality studies.

CONCLUSIONS

There is a paucity of high quality evidence to identify risk factors associated with heel pressure ulcer development. Immobility, diabetes, vascular disease, impaired nutrition, perfusion issues, mechanical ventilation, surgery, and Braden subscales were identified as potential risk factors for developing heel pressure ulcers however, further well-designed studies are required to elucidate these factors. Other risk factors may also exist and require further investigation.

The Impact of COVID-19 on Levels of Adherence to the Completion of Nursing Records for Inpatients in Isolation

The COVID-19 pandemic has led to an increased workload for nurses and organisational and structural changes, which have been necessary to meet the needs of inpatients in isolation.

AIM

To describe the impact of the COVID-19 pandemic on levels of adherence to the completion of nursing records that document the risk of developing pressure ulcers, falling, and social vulnerability among hospitalised patients in isolation.

METHODS

Observational pre-post comparison study. Comparison between nursing records (the Braden, Downton, and Gijón scales) belonging to 1205 inpatients took place in two phases. Phase 1: 568 patients admitted in February 2020, prior to the COVID-19 pandemic, vs. phase 2: 637 patients hospitalised with COVID-19 in March-April 2020, during the peak of the first wave of the pandemic. This research adheres to the STROBE guidelines for the reporting of observational studies.

RESULTS

The degree of completion of the Braden, Downton, and Gijón scales decreased significantly in phase 2 vs. phase 1 (p < 0.001). The mean Downton and Gijón scale scores for patients admitted in phase 1 were higher compared to those of patients admitted in phase 2 (p < 0.001). The mean Braden scale score in phase 2 was higher than in phase 1 (p < 0.05).

CONCLUSION

During the COVID-19 pandemic, there was a decrease in the completion of nursing records in the clinical records of patients in isolation. The levels of risk of developing PUs, falling, and social vulnerability of patients admitted to hospital were lower during the first wave of the pandemic.

Development and validation of the Pressure Injury Prevention Barriers questionnaire in hospital nurses in Spain

OBJECTIVE

To develop and validate a new questionnaire to measure the nurses' perceptions of the barriers towards the prevention of pressure injuries (PIs) at hospitals.

DESIGN

Validation study with mixed methods.

SETTING

Four university hospitals in southern Spain.

PARTICIPANTS

The questionnaire was developed based on a literature review. A panel of 14 wound care experts rated the content validity. A sample of 438 nurses (registered nurses and assistant nurses) participated in the survey.

MAIN OUTCOME MEASURES

The psychometric properties of the Pressure Injury Prevention Barriers (PIPB) questionnaire evaluated were: content validity, internal consistency reliability and construct validity.

RESULTS

The final version of the questionnaire has 25 items grouped into four factors (management and organisation, motivation and priority, knowledge, and staff and collaboration). The confirmatory factor analysis showed good fit and error indices for the model (Comparative Fit Index=0.92, root mean square error of approximation=0.074). Cronbach's alpha was 0.90 (overall), and 0.89 (factor 1), 0.75 (factor 2), 0.72 (factor 3) and 0.45 (factor 4). Construct validity was good, demonstrated by the expected association with the scores on patient safety culture and on considering PIs as an adverse effect of hospital stay, but not with attitude score.

CONCLUSION

The PIPB questionnaire is an instrument useful for measuring nurses' perceptions of the barriers to PIs prevention. The initial evidence shows that the questionnaire has good content validity, internal consistency and adequate construct validity. Relevance and comprehensiveness need to be assessed in further studies. It can be used both in research and in the evaluation of clinical settings to implementation of PIs preventive programmes in hospitals.
