Introducing the pressure support surfaces from Kaymed

The range of support surfaces available is quite varied. It is important that both the purchaser and the users are satisfied with the quality, comfort and the pressure-reducing properties of the mattress. The mattress needs to be versatile, in that it can be used both in a patient's home or in a hospital or nursing home and also on profiling beds. The Kaymed range of mattresses offers increased comfort with low interface pressures for patients up to and including high risk. This product focus examines the Kaymed mattress and looks at the design and results of tests performed on the visco-elastic foam used in the manufacturing of the mattresses.     

Preventing pressure ulcers: an evaluation of four operating-table mattresses.

Pressure is a major factor in the development of pressure ulcers. This research focused on assessing the pressure-reducing effects of operating-table mattresses. Five mattresses were tested: a standard operating-table mattress, a foam mattress, a gel mattress, a visco-elastic polyether mattress, and a visco-elastic polyurethane mattress. Four intraoperative postures were evaluated: supine, lateral, fossa, and the Miles-Pauchet position. Interface pressure measurements were performed on 36 healthy volunteers. The foam mattress and the gel mattress seem to have little or no pressure-reducing effect; the polyurethane mattress and the polyether mattress reduce interface pressure significantly better (p < .001); but none of the mattresses reduce pressure sufficiently to prevent the occurrence of pressure ulcers.     

Factors contributing to evidence-based pressure ulcer prevention. A cross-sectional study

Background

Implementation of evidence-based care for pressure ulcer prevention is lacking. As the hospital organization is complex, more knowledge is needed to understand how nursing care in this area can be improved.

Objectives

The present study investigated the associations between variables on different levels in the healthcare setting (patient, unit, hospital) and the documentation of (1) risk assessment and (2) skin assessment within 24 h of admission, the use of (3) pressure-reducing mattresses and (4) planned repositioning in bed.

Design

A cross-sectional study.

Settings

One university hospital and one general hospital.

Participants

Geriatric (n = 8), medical (n = 24) and surgical (n = 19) units. All adult patients (>17 years), in total 825, were included.

Methods

A one-day prevalence study was conducted using the methodology specified by the European Pressure Ulcer Advisory Panel, together with the established methods used by the Collaborative Alliance for Nursing Outcomes. Independent variables were patient characteristics, hospital type, unit type, nurse staffing and workload. Dependent variables were documented risk and skin assessment within 24 h of admission, pressure-reducing mattresses and planned repositioning in bed. The data were analysed with Logistic regression using the Generalized Estimating Equation (GEE) approach.

Results

Patients at risk of developing pressure ulcers (Braden < 17) had higher odds of having risk assessment documented, and of receiving pressure-reducing mattresses and planned repositioning. Patients at the general hospital were less likely to have risk and skin assessment documented and to receive pressure-reducing mattresses. On the other hand, planned repositioning was more likely to be used at the general hospital. When total hours of nursing care was lower, patients had higher odds of having pressure-reducing mattresses but were less likely to have planned repositioning.

Conclusion

Patient characteristics (high age and risk score) and hospital type were associated with pressure ulcer prevention. Surprisingly, nurse staffing played only a minor role. Leaders in healthcare organizations should establish routines on different levels that support evidence-based pressure ulcer prevention, and registered nurses need to assume responsibility for bedside care.     

Use of Pressurease and Airform mattresses in pressure ulcer care

Large cell dynamic air mattresses are effective in the prevention of pressure ulcers but they still have inherent problems, e.g. the ability of the mattresses to move patients along the mattress through the inflation and deflation of the cells. Also, there have been reports that the inflation and deflation of cells can cause motion sickness. This article reviews two mattresses from Sareo Healthcare Ltd: a static system, Pressurease; and a unique dynamic system, Airform. These two systems offer a cost-effective and clinically effective method of pressure ulcer prevention and therapy.     

Differences in prevalence of pressure ulcers between the Netherlands and Germany--associations between risk, prevention and occurrence of pressure ulcers in hospitals and nursing homes

Aim. This study compares pressure ulcer prevalence and prevention activities in nursing homes and hospitals within two European countries. Background. Over three years stable differences have been found between the Netherlands (NL) and Germany (GER) with higher pressure ulcer rates in the NL. As previous analyses have shown, the differences cannot be entirely explained by differences in the population’s vulnerability to pressure ulcers because they still remain after risk adjustment. Therefore, the differences in prevalence must be caused by other factors. The purpose of this study is to analyse if any potential differences in preventive activities can account for the varying occurrence of pressure ulcers. Method. In both countries, nation-wide surveys were conducted annually using the same standardised questionnaires. Trained nurses examined all consenting patients of the voluntarily participating facilities. This examination included a skin assessment of the entire body. Data regarding risk factors, prevention and details about wounds were then collected. Results. In-patients of 29 German (n = 2531) and 71 Dutch (n = 10 098) nursing homes and 39 German (n = 8515) and 60 Dutch (n = 10 237) hospitals were investigated. The use of pressure-reducing devices was more common in the NL than in GER, but all other interventions were more frequently provided to German risk patients than to their Dutch counterparts. The pressure ulcer prevalence was significantly higher in the Dutch sample. After adjusting for gender, age, Braden Score and prevention, the probability of having a pressure ulcer was 8·1 times higher for Dutch nursing home residents than for German residents. Conclusion. Some of the variance in pressure ulcer prevalence between the two countries can be explained by varying pressure ulcer prevention. However, some remarkable differences still remain unexplained. Relevance to clinical practice. The extent of pressure ulcer prevention, especially repositioning and nutrition intervention provided to patients at risk, is not in accordance with international guidelines.     

Guideline implementation results in a decrease of pressure ulcer incidence in critically ill patients

OBJECTIVE: To describe the short-term and long-term effects of a hospital-wide pressure ulcer prevention and treatment guideline on both the incidence and the time to the onset of pressure ulcers in critically ill patients. DESIGN: Prospective cohort study. SETTING: Adult intensive care department of a university medical center. PATIENTS: Critically ill patients (n = 399). INTERVENTIONS: A guideline for pressure ulcer care was implemented on all intensive care units. The attention of nurses for timely transfer to a specific pressure-reducing device was an important part of this guideline. MEASUREMENTS AND MAIN RESULTS: Patient characteristics, demographics, pressure ulcer risk profile at admission, daily pressure ulcer grading, and type of mattress were determined to describe the short-term and long-term effects 3 and 12 months after the implementation. The incidence density of pressure ulcers grade II-IV decreased from 54 per 1000 patient days at baseline to 32 per 1000 days (p = .001) 12 months after the implementation. The median pressure ulcer-free time increased from 12 days to 19 days (hazard rate ratio, 0.58; p = .02). After adjustment for differences in risk factors in a Cox proportional hazard model, the number of preventive transfers to special mattresses was the strongest indicator for the decreased risk of pressure ulcers (hazard rate ratio, 0.22; p < .001). The number needed to treat to prevent one pressure ulcer during the first 9 days was six. CONCLUSIONS: The implementation of a guideline for pressure ulcer care resulted in a significant and sustained decrease in the development of grade II-IV pressure ulcers in critically ill patients. Timely transfer to a specific mattress (i.e., transfer before the occurrence of a pressure ulcer) was the main indicator for a decrease in pressure ulcer development.     

Prevention and early detection of pressure ulcers in patients undergoing cardiac surgery

•

ABSENCE OF PRESSURE ULCERS is increasingly being used as an indicator of quality nursing care, based on the premise that pressure ulcers are preventable.

•

THIS RETROSPECTIVE STUDY examined the occurrence, presentation, and timing of pressure ulcer development in 150 patients undergoing cardiac surgery.

•

PRESSURE ULCER INCIDENTS were recorded in groups of patients who underwent surgery with use of a standard foam OR bed mattress; use of a fluid, pressure-reducing OR bed mattress; or use of a fluid, pressuring-reducing mattress after a comprehensive educational program on pressure ulcer prevention was presented to RNs.

•

THE NUMBER of pressure ulcers decreased when the fluid, pressure-reducing OR bed mattresses were used in conjunction with the comprehensive RN education program. AORN J 84 (July 2006) 75-96. © AORN, Inc, 2006.

     

Pressure ulcer development in older residents in nursing homes: influencing factors

Title. Pressure ulcer development in older residents in nursing homes: influencing factors. Aim. This paper is a report of a study assessing pressure ulcer incidence and factors affecting pressure ulcer development among older nursing home residents. Background. Previous researchers have shown that demographic, clinical, health status, risk and human resources factors affect pressure ulcer development among older people in various healthcare settings, but none has investigated their interactive effects among older nursing home residents. Method. This was a prospective cohort study involving 346 residents aged 65 years or over from four private nursing homes in Hong Kong. We collected information on participant demographics and assessed their clinical characteristics, health status and pressure ulcer risk factors. Subsequently, we assessed their skin condition every 2 days for 4 weeks to detect pressure ulcers that developed after the initial assessment. The data were collected between December 2006 and September 2007. Results. The pressure ulcer incidence was 25·16%. The model in which the factors of clinical characteristics, health status, pressure ulcer risk and human resources were controlled was more reliable in predicting pressure ulcer development than the other two models. It showed that bedfast or chairfast residents, especially those with co‐morbidities (renal failure and stroke) and living in nursing homes where there were no nurses but more nursing assistants, were at higher risk for pressure ulcer development. Conclusion. Evidence‐based interventions should be adopted to minimize the possible problems of pressure, malnutrition, friction and shear force, and the decreased pain perception of bedfast or chairfast residents in nursing homes, especially those with renal failure or stroke.     

A clinical evaluation of the Transfoam mattress after 4 years

It is recognized that pressure-reducing foam mattresses can be of benefit in the prevention of pressure sores but it is also recognized that more information is required to demonstrate their long-term efficacy (Cullum et al, 1995). It is therefore necessary to evaluate the pressure-reducing capabilities of this type of mattress some years after purchase to evaluate if in fact it can maintain its initial level of performance. This article presents the results of one such study carried out 4 years after the purchase of Transfoam mattresses.     

Explaining the national differences in pressure ulcer prevalence between the Netherlands and Germany – adjusted for personal risk factors and institutional quality indicators

Background Pressure ulcers have a known impact on quality of life as well as on morbidity and mortality of the persons affected. Remarkable differences in pressure ulcer prevalence between the Netherlands and Germany have been found during the last 6 years. This study explores to what extent the individual risk of the population and quality indicators of the institutions can explain the variation in national prevalence. Methods Data of a binational multi‐centred cross‐sectional study in 103 hospitals (n = 21 378 patients) and 129 nursing homes (n = 15 579 residents) were analysed using random effects regression models to calculate the differences in national prevalences within the nursing homes and hospitals, adjusted for personal risk for pressure ulcer and quality indicators. Results The prevalence of pressure ulcers among the at‐risk group (Bradenscore ≤20) in nursing homes was 30.8% in the Netherlands and 8.3% in Germany [OR: 4.9 (CI 95%: 4.2–5.7)]. In hospitals, the prevalence among the at‐risk group was 26.1% in the Netherlands and 21.2% in Germany [OR: 1.3 (CI 95%: 1.2–1.5)]. After adjusting for individual risk factors (age, gender, Bradenscore) as well as for quality structures (use of prevention and treatment protocols, experts groups, information leaflets, nurses training, central pressure ulcer statistics and regular updating of protocols), the chance of developing a pressure ulcer was 6.05 times higher (CI 95%: 4.0–9.2) in a Dutch nursing home than in a German nursing home. Within the hospitals, the OR for Dutch patients was 2.03 (CI 95%: 1.4–3.0). Conclusion A remarkable national variation exists in pressure ulcer prevalence and nursing practice. Neither the populations vulnerability for pressure ulcers nor pressure ulcer management as measured in this study could explain this national variation. Therefore, other risk factors should be taken into consideration. Additionally, it is possible that quality indicators are implemented in differing ways with varying levels of effectiveness. Therefore, further research is needed to examine prospectively and in more detail the reality of care within facilities in both countries.     

Preventing pressure ulcers: choosing a mattress

The standard hospital mattress is not suitable for patients at risk of developing pressure ulcers. The type of mattress or overlay system they require will depend on their pressure ulcer risk, medical history and local practice. This article provides a guide to pressure-relieving mattresses.     

Evaluation of patient outcomes: pressure ulcer prevention mattresses

This article reports the findings of a small evaluation audit which compares the Dyna-Form Mercury Advance Mattress to that of the Softform Premier Active Mattress (a foam mattress with dynamic underlay). A small group of patients with similar co-morbidities who were an emergency admission were recruited to an evaluation audit. Their median age and Waterlow score indicated that these patients were at high risk of pressure ulcer development. All patients were given the same nursing care on the two mattresses and all were moved, handled and repositioned 2-4 hourly. Of the patients nursed on the Dyna-Form Mercury Advance mattress, three did not develop pressure ulcers. The two who already had pressure ulcers when they were recruited appeared to have healed within four days. Of the patients nursed on the Softform Premier Active mattress, three patients did not develop ulcers and two did. Although the sample size was small, the comprehensive assessment gave interesting results, particularly on the Dyna-Form Mercury Advance. A larger study may be of benefit to demonstrate efficacy of these products further.     

Efficacy and cost-effectiveness of the Thermo contour mattress

Use of air mattresses in reduction of pressure sore incidence is an important part of quality patient care. However, there will never be enough air mattresses to match the demand as increased education and an increase in the general provision of air mattresses can lead to an unrealistic expectation of obtaining air mattresses when required for patients. This raises the demand for air mattresses and increases costs within hospital trusts. This study examined a way to redress the balance through use of an alternative, cost-effective type of mattress (thermoelastic polymer) in the prevention of pressure sores. Prime consideration was given to the comfort of the patient. The claims of the manufacturers, Barrington Healthcare, that 'patients with Waterlow scores of 23 can be nursed safely on this product' were explored as part of the study. A total of 407 patients took part over a 6-month period. Twenty-four Thermo contour mattresses were loaned to one ward for the study and patients were allocated to the mattress through admission to the experimental ward. Patients were then split into two groups on two wards. Group B were allocated to a Thermo contour mattress and group A were nursed on air mattresses and foam mattresses generally used throughout the trust. Results showed that more patients were comfortable on the Thermo contour mattresses than on all other mattresses. Patients with Waterlow scores under 25 did not develop pressure sores on the Thermo contour mattress. However, the sample of patients with a Waterlow score of between 20 and 25 was small and therefore further research is required.     

The effect of various combinations of turning and pressure reducing devices on the incidence of pressure ulcers

BACKGROUND: Turning is considered to be an effective way of preventing pressure ulcers, however almost no research has been undertaken on this method. AIM: The aim of the study was to investigate the effect of four different preventative regimes involving either frequent turning (2, 3 hourly) or the use of a pressure-reducing mattress in combination with less frequent turning (4, 6 hourly). SUBJECTS: 838 geriatric nursing home patients participated in the study. METHODS: During 28 days, four different turning schemes were used: turning every 2 h on a standard institutional (SI) mattress (n = 65), turning every 3 h on a SI mattress (n = 65), turning every 4 h on a viscoelastic foam (VE) mattress (n = 67), and turning every 6h on a VE mattress (n = 65). The remaining patients (n = 576) received standard preventive care. MAIN RESULTS: The incidence of non-blanchable erythema (34.8-38.1%) was not different between the groups. The incidence of grade II and higher pressure ulcers in the 4h interval group was 3.0%, compared with incidence figures in the other groups varying between 14.3% and 24.1%. CONCLUSIONS: Turning every 4 h on a VE mattress resulted in a significant reduction in the number of pressure ulcer lesions and makes turning a feasible preventive method in terms of effort and cost.     

Skin problems: epidemiology of pressure ulcers in a skilled care facility.

The majority of nursing home residents have conditions that place them at risk for the development of pressure ulcers. Reported pressure ulcer prevalence rates range from 16% to 35%. Pressure ulcers are multifactorial in origin and necessitate ongoing vigilance by the entire health-care team. Associated risk factors include impairments of circulation, sensation, physical condition, nutrition, mobility, and activity. Stage I pressure ulcers frequently go unrecognized, yet their recognition is essential to prevent further damage. Comprehensive initial assessments of the skin and risk factors of pressure ulcer development at admission will allow for easier reassessment and comparison.     

Effectiveness of turning with unequal time intervals on the incidence of pressure ulcer lesions

AIM: This paper reports a study investigating whether repositioning patients lying on a pressure-reducing mattress alternately for 2 hours in a lateral position and 4 hours in a supine position reduces the incidence of pressure ulcers in comparison with repositioning every 4 hours. BACKGROUND: Repositioning is commonly recognized as an effective preventive measure. Almost no research has been carried out so far on the necessary turning frequencies to prevent pressure ulcer lesions. The pressure is higher in a lateral than in a supine position. METHOD: A two-arm randomized controlled trial was conducted in 16 Belgian elder care nursing homes. Patients with non-blanchable erythema were randomly assigned to either an experimental or a control group. In the experimental group (n = 122), patients were repositioned alternately 2 hours in a lateral position and 4 hours in a supine position. In the control group (n = 113), patients were repositioned every 4 hours. The sitting protocol was identical in both groups. Pressure areas were observed daily and classified according to the four grades of the European Pressure Ulcer Advisory Panel. RESULTS: In the experimental group, 16.4% patients developed a pressure ulcer lesion (grade 2-4), while 21.2% did so in the control group. The incidence was not statistically significantly different between the two groups (P = 0.40). The severity (P = 0.65) and location (P = 0.19) of pressure ulcer lesions, and the time to developing them (P = 0.29) were also similar in both groups. No patient developed a pressure ulcer at the hips. A considerable number of patients changed from a lateral to a supine position between the turning intervals. CONCLUSION: More frequent repositioning on a pressure-reducing mattress does not necessarily lead to fewer pressure ulcer lesions and consequently cannot be considered as a more effective preventive measure.     

The identification of older nursing home residents vulnerable for deterioration of grade 1 pressure ulcers

Aims and objective. The objective of this study was to identify prognostic factors associated with the development of pressure ulcer lesions (grade 2–4) in nursing home patients with non‐blanchable erythema. Background. No studies could be found that identify risk factors for further development of pressure ulcer in patients with non‐blanchable erythema. For some patients with non‐blanchable erythema, standard preventive measures do not suffice to prevent pressure ulcers from deterioration. Identifying these patients beforehand can considerably contribute to the efficiency of pressure ulcer prevention. Design. Secondary data analyses of a previously conducted randomised controlled trial were performed. Methods. Eighty‐four wards of 16 Belgian nursing homes participated in the study. In total, 235 nursing home residents with a grade 1 pressure ulcer (non‐blanchable erythema) were included. All the residents received standard preventive care. Potential prognostic factors were collected using a standardised form. The incidence of pressure ulcers was recorded according to the European pressure ulcer classification system. Results. The cumulative pressure ulcer incidence was 18·7% (44/235). Hypotension (relative risk = 3·42, 95% CI = 1·56–7·49), a history of a cerebral vascular accident (relative risk = 1·94, 95% CI = 1·10–3·70) and contractures (relative risk = 2·02, 95% CI 1·03–3·95) were identified as independent predictive factors for developing pressure ulcers. Remarkably, being urinary incontinent decreased the risk of developing a pressure ulcer by 76%. Conclusions. In nursing home residents with non‐blanchable erythema, hypotension, contractures, and a history of cerebral vascular accident were independent risk factors for the development of pressure ulcer lesions. Relevance to clinical practice. Patients with non‐blanchable erythema who have hypotension, contractures or a history of cerebral vascular accident are in need of more intensive preventive measures. Identifying these patients can contribute considerably to a more efficient pressure ulcer prevention policy, resulting in a lower pressure ulcer lesion incidence and in lower costs.     

The first national pressure ulcer prevalence survey in county council and municipality settings in Sweden

Aim To report data from the first national pressure ulcer prevalence survey in Sweden on prevalence, pressure ulcer categories, locations and preventive interventions for persons at risk for developing pressure ulcers. Methods A cross‐sectional research design was used in a total sample of 35 058 persons in hospitals and nursing homes. The methodology used was that recommended by the European Pressure Ulcer Advisory Panel. Results The prevalence of pressure ulcers was 16.6% in hospitals and 14.5% in nursing homes. Many persons at risk for developing pressure ulcers did not receive a pressure‐reducing mattress (23.3–27.9%) or planned repositioning in bed (50.2–57.5%). Conclusions Despite great effort on the national level to encourage the prevention of pressure ulcers, the prevalence is high. Public reporting and benchmarking are now available, evidence‐based guidelines have been disseminated and national goals have been set. Strategies for implementing practices outlined in the guidelines, meeting goals and changing attitudes must be further developed.
