The role of nutrition in prevention and healing of pressure ulcers

A quality improvement programme to reduce hospital-acquired pressure injuries

Background

At Heart Hospital in Doha, Qatar (HH), 127 pressure injuries (PI) were identified in 2014, corresponding to an incidence of 6.1/1000 patient-days in first 4 months of 2014. Hospital-acquired pressure injury (HAPI) is one of the most common preventable complications of hospitalisation. HAPI significantly increases healthcare costs, including use of resources (dressings, support surfaces, nursing care time and medications). They also have a significant impact on patients in terms of pain, worsened quality of life, psychological trauma and increased length of stay. Working with the Institute for Healthcare Improvement (IHI), we implemented evidence-based practices in all In patient Units at HH with the aim of reducing the number of HAPIs by 60% within 2 years.

Methods

In collaboration with IHI, our multidisciplinary clinical and risk assessment teams tested several changes and implemented a successful programme. The Surface, Skin inspection, Keep moving, Incontinence and Nutrition bundle was implemented. Signs, turning clocks and PI incidence ‘calendars’ were used in the units as reminders. Attention was paid to endotracheal tube ties in order to address device-related pressure injuries. Counts of HAPI (incidence) and number of PIs per 100 patients surveyed (prevalence) were prominently displayed. Changes were tested using the Plan-Do-Study-Act methodology. Statistical analysis using the independent t-test was applied to detect the significance of any difference in the incidence of HAPI before and after implementation of the changes.

Results

The incidence of HAPI dropped from 6.1/1000 patient-days to 1.1/1000 patient-days, an 83.5% reduction. The prevalence, based on quarterly survey fell from 9.7/100 patients surveyed to 2.0/100 patients surveyed, a 73.4% decline.

Conclusions

The interventions proved to be successful, reducing the incidence of PI by >80%. The outcomes were sustained over a 4-year period.

Active topical therapy by "Furuta method" for effective pressure ulcer treatment: a retrospective study

Background

We newly proposed that “Furuta method,” a pharmacist intervention guidelines, is a topical ointment therapy that considers the physical properties and moist environment of wounds for pressure ulcer (PU) treatment. The aim of this multicenter retrospective study was to investigate the effectiveness of this method for PU.

Methods

A total of 888 consecutive patients who underwent treatment for PU at 37 hospitals and five dispensing pharmacies in Japan between August 2010 and July 2014 were included in the study. Based on a survey on compliance to “Furuta method,” single-blind allocation was conducted into compliance (n = 437) and non-compliance (n = 451) groups, followed by a retrospective data collection. The primary and secondary outcomes were the healing period and rates of unhealed wounds, respectively. Data was expressed as mean ± standard deviation. Two-sided log rank tests were used for between-group comparisons of PU progression, whereas Kaplan–Meier plots were used for comparison between groups. We performed rigorous adjustment for marked differences in baseline patient characteristics by propensity score (PS) matching.

Results

After PS matching, patients were categorized as DESIGN-R d2 (n = 202), D3 (n = 130), D4 and 5 (n = 76), and DU (n = 76). In terms of the healing period, the patients in the compliance groups healed faster than those in the non-compliance groups in d2 (23.6 ± 36.8 vs. 32.2 ± 16.6 days; P < 0.001), D3 (46.8 ± 245.5 vs.137.3 ± 52.7 days; P < 0.001), and D4, 5 (122.5 ± 225.7 vs. 258.2 ± 292.7 days; P < 0.001). There were significantly lesser events of PU progression in the compliance group than in the non-compliance group (15 vs. 54; P = 0.003).

Conclusions

“Furuta method” is the new therapeutic strategy of PU, a pharmacist intervention guidelines, may possibly increase healing rates of PUs.

[Efficacy and safety of symphytum herb extract cream in the treatment of pressure ulcers]

In an open, prospective use study, 161 patients with 198 decubitus ulcers (pressure ulcers, ITT population) in stages II and III were treated with the topical preparation symphytum herb extract cream. The bandages with the cream were changed every 2-3 days. The primary parameters evaluated were the area of the sore and the depth of the wound (planimetrically in mm). In all, 151 patients with a total of 184 pressure sores (PP population) were included and received treatment over a period of 4 weeks in order to evaluate the treatment results. Complete healing of the pressure sores within 4 weeks was observed in 85.9 % (PP population)/79.8 % (ITT population) of the treated ulcers. Over a treatment duration of 25-30 days, a 89.2 % reduction of the total decubitus area was observed. The same result was found for the depth of the pressure ulcer with a reduction of 88 %. The overall treatment success was from both the perspective of the physician and the patient considered successful in 90.4 % (5-point scale) of cases and 87.9% (100 mm VAS, PP population). Two cases of local irritation were observed after 25/30 days (1.2 % of the patients with exposure), thus showing very good skin compatibility. The efficacy of symphytum herb extract cream is surprisingly good in the treatment of pressure ulcers.

The Topical Evolution: Free Ions, Orthomolecular Agents, Phytochemicals, and Insect-Produced Substances

Significance: A variety of topical antiseptic substances have been used historically to treat open wounds with suspected tissue infection or that are slow to heal. However, the effectiveness of these substances in treating infected or recalcitrant wounds remains controversial. Recent Advances: Newly formulated topical antiseptics delivered through differing dressing technologies, such as ionic substances, hold the potential to limit the development of and treat antibiotic-resistant microbes in open wounds. Other topically delivered substances, such as insect-derived substances, orthomolecular agents, and phytochemicals, also present opportunities to optimize wound healing by decreasing tissue bioburden and facilitating the wound healing process. Critical Issues: Limited systemic perfusion of open wounds in individuals with certain diagnoses, such as peripheral arterial disease or necrotizing infection and the increasing number of antibiotic-resistant wound pathogens, suggests a continued role for topically applied antiseptic agents. Likewise, the failure of wounds to heal when treated with standard of care therapy opens the door to innovative treatment approaches that include the natural substances described in this article. Future Directions: Evidence for the use of select topical antiseptic agents from each of the aforementioned categories will be discussed in this article. Additional well-controlled clinical studies are needed to provide definitive recommendations for many of these topical agents.

Prevalence of malnutrition in orally and tube-fed elderly nursing home residents in Germany and its relation to health complaints and dietary intake

Objective. To investigate the prevalence of malnutrition in orally and tube-fed nursing home (NH) residents in Germany and its relation to common health complaints and dietary intake. Methods. In 350 NH residents, subjects' characteristics, Mini Nutritional Assessment (MNA), and several health problems were inquired with the nursing staff using standardised interviews. In a subset of 122 residents, dietary intake was assessed by 3-day weighing records. Results. 7.7% of the participants were tube fed. 24.1% of orally nourished and 57.7% of tube-fed residents were malnourished (MNA < 17 p.). Malnutrition was significantly related to nausea/vomiting, constipation, pressure ulcers, dehydration, infections, antibiotic use, and hospitalisation. Mean daily energy intake was 1535 ± 413 kcal and mean protein intake was 54.2 ± 0.9 g/d irrespective of the nutritional state. Conclusion. In Germany, malnutrition is widespread among NH residents and is related to common health problems. The MNA rather reflects health condition than currently reduced dietary intake.
