Effects of warming therapy on pressure ulcers--a randomized trial

Postoperative pressure ulcers are a common and expensive problem. Intraoperative hypothermia also is a common problem and may have a connection with impaired tissue viability. Researchers in this study hypothesized that intraoperative control of hypothermia may reduce the incidence of postoperative pressure ulcers. A randomized clinical trial (n = 338) was used to test the effects of using forced air warming therapy versus standard care. Results indicated an absolute risk reduction in pressure ulcers of 4.8% (i.e., 10.4% to 5.6%) with a relative risk reduction of 46% in patients who received warming therapy. Although not reaching statistical significance, the clinical significance of almost halving the pressure ulcer rate is important. A correlation between body temperature and postoperative pressure ulcers was established.     

Risk assessment for pressure ulcer in critical patients

Bedridden patients are in risk to developing pressure ulcers and represent a priority group to be studied to identify this condition. To reach this goal, specific instruments are used to assess this problem. The objective of this study was to analyze the risk factors to developing pressure ulcers in adult patients hospitalized in ICUs. This is a sectional analytical study, in which evaluations were performed on 140 patients, hospitalized in 22 ICUs, using the Braden scale. Results showed that patients hospitalized from 15 days or more showed some level of risk. The highest frequencies of pressure ulcers were found in patients in the following categories: sensorial perception (completely limited), moistness (constantly moist), mobility (completely immobilized), activity (bedridden), nutrition (adequate) and friction and shear (problem). In conclusion, the use of this scale is an important strategy when providing care to patients in intensive treatment.     

Pressure Ulcer Prevalence and Incidence in a Rehabilitation Hospital

Pressure ulcers remain a serious health problem, especially in terms of personal suffering and economics. The study described here, conducted in a rehabilitation setting, investigated the prevalence (number of persons with pressure ulcers at a given time) and the incidence (number of persons developing pressure ulcers over a given time) of pressure ulcers. Skin assessments and risk assessments of the subjects were completed using the Braden Scale for Predicting Pressure Sore Risk. Demographic data were obtained. The prevalence rate was 25%, although there was no incidence during the time of this study. Factors associated with the prevalence of pressure ulcers are discussed.     

Clinical Use of Interface Pressure to Predict Pressure Ulcer Development: A Systematic Review

ABSTRACT

Pressure ulcers are a large problem in subjects who use a wheelchair for their mobility. These ulcers originate beneath the bony prominences of the pelvis and progress outward as a consequence of prolonged pressure. Interface pressure is used clinically to predict and prevent pressure ulcers. However, the relation between interface pressure and the development of pressure ulcers is not clear. A systematic review was performed to address the research question of whether interface pressure can be used to predict the development of pressure ulcers or to determine the prognosis of an ulcer once developed. Seven studies were identified that measured interface pressure and used the development or healing of pressure ulcers as an outcome measure. There appears to be a weak qualitative relation between interface pressure and the development of pressure ulcers. However, no conclusive clinical threshold for the interface pressure can be given. This, combined with the influence of individual characteristics, the low internal validity of interface pressure measurement for the prediction of pressure ulcers, and an incongruent relation between pressure magnitude and duration, results in the fact that no quantification of the predictive or prognostic value of interface pressure can be given.     

Pressure ulcers in infants and children

Although there is no agreement about the size of the problem, there is evidence that critically ill children are more at risk of pressure ulcers than the general paediatric population. In addition to tissue damage associated with immobility, equipment and objects pressing or rubbing on the child's skin have also been implicated in the development of pressure ulcers. To prevent disfiguring and potentially life-threatening pressure ulcers, it is important that risk factors are identified and minimised.     

Pressure ulcer prevalence and incidence in intensive care patients: a literature review

Background: Pressure ulcers remain a common health problem worldwide within the different health‐care settings, especially in intensive care settings. Aims: The aims of this were to systematically assess the recent prevalence and incidence of pressure ulcers in intensive care patients (2000–2005), the factors related to pressure ulcer prevalence and incidence and the methodological rigour of studies about pressure ulcer prevalence and incidence in intensive care patients. Methods: The research design involved a review of literature for the period of 2000 to 2005, focused on the prevalence and incidence of pressure ulcers in intensive care patients. Results: The analysis of published papers revealed variations in pressure ulcer prevalence in intensive care settings ranging from 4% in Denmark to 49% in Germany, while incidence ranged from 38% to 124%. There was a wide variation in the prevalence and incidence of pressure ulcers in intensive care patients as evidenced in the studies examined. There is also a gap between theory and practice in the prevention and treatment of pressure ulcers which needs to be addressed. Conclusion: Further research is needed regarding the effectiveness of nursing care on pressure ulcer development and into treatments that may successfully prevent their occurrence in intensive care patients.     

TREATMENT OF PRESSURE ULCERS*

A review of approaches to prevention and treatment of pressure ulcers, this article's aim is to encourage more research on a long-neglected problem.     

Surgical treatment of pressure ulcers

The authors' philosophy and regimen of treatment, based on experience with 103 pressure ulcers in 75 patients, are presented. This experience illustrates that the problem of pressure ulcers can be managed well by the application of sound surgical principles in a community hospital with a rehabilitation unit. With some simplification, the standard treatment procedures can be applied easily in this setting.     

Pressure ulcers in veterans with spinal cord injury: a retrospective study

Pressure ulcers are a major complication of spinal cord injury (SCI) and have a significant effect on general health and quality of life. The objectives of this retrospective chart review were to determine prevalence, duration, and severity of pressure ulcers in veterans with SCI and to identify predictors of (1) outcome in terms of healing without surgery, not healing, or referral for surgery; (2) number of visits veterans made to the SCI outpatient clinic or received from home care services for pressure ulcer treatment; and (3) number of hospital admissions and days hospitalized for pressure ulcer treatment. From a sampling frame of 553 veterans on the Houston Veterans Affairs Medical Center SCI roster, 215 (39%) were reported to have visited the clinic or received home care for pressure ulcers (ICD-9 code 707.0 = decubitus, any site) during the 3 years studied (1997, 1998, and 1999). From this sample, 102 veterans met the inclusion criteria for further analyses, 56% of whom had paraplegia. The duration of ulcers varied greatly from 1 week to the entire 3-year time-frame. Overall, Stage IV pressure ulcers were the most prevalent as the worst ulcer documented. Number and severity of ulcers predicted outcome and healthcare utilization. This study illustrates the magnitude of the pressure ulcer problem among veterans with SCI living in the community. Reducing the prevalence of pressure ulcers among veterans with SCI will have a significant impact on the Department of Veterans Affairs' financial and social resources. Innovative approaches are needed to reduce pressure ulcer risk in veterans with SCI.     

Incidence of pressure ulcers due to surgery

Patients undergoing surgery are prone to develop pressure ulcers during the surgical procedure. The aim of the study was to gain insight into the problem by describing the incidence, clinical features and progression of pressure ulcers and closed pressure ulcers in patients undergoing surgery lasting more than 4 hours. A prospective follow-up study was conducted in a university hospital in the Netherlands. Two-hundred and eight patients from nine surgical specialities were included in the study. The skin of patients was observed the evening before surgery and, if the patient's condition allowed it, directly postoperatively and subsequently daily for 14 days or until discharge, whichever occurred first. When patients developed a pressure ulcer they were observed daily until discharge or until the pressure ulcer had healed. The size and colour of the lesion, stage and skin condition were described every day. In addition, data were collected concerning the operation, postoperative period, and general characteristics. Forty-four patients (21.2%) developed 70 pressure ulcers in the first 2 days following surgery. Twenty-one pressure ulcers deteriorated in the days following surgery. More than half (52.9%) of the lesions developed on the heels, and 15.7% developed in the sacral area. Twenty-five patients (12%) were impaired by the lesions they developed. None of the patients in the study developed closed pressure ulcers. Pressure ulcer development during a surgical procedure is a serious problem. Therefore, preventive measures should be taken during surgery and the first few days afterwards, until the patient is able to mobilize independently.     

Preventing heel breakdown

The prevalence of heel pressure ulcers is a major health care problem. Heel ulcers develop as a result of pressure, shear, or friction concentrated on a small area over a bony prominence that lacks subcutaneous tissue. Significant risk factors for development of heel breakdown include immobility, age, mental status, nutrition, chronic illness, and orthopaedic surgical procedures, especially hip pinning and hip replacement surgeries. It is important for nurses to identify patients at risk for heel pressure ulcers and to initiate appropriate preventive interventions. This article discusses the etiology of heel pressure ulcers, risk factors, heel assessment, and choice of heel protection devices.     

Inter-rater reliability of the EPUAP pressure ulcer classification system using photographs

Background. Many classification systems for grading pressure ulcers are discussed in the literature. Correct identification and classification of a pressure ulcer is important for accurate reporting of the magnitude of the problem, and for timely prevention. The reliability of pressure ulcer classification systems has rarely been tested. Aims and objectives. The purpose of this paper is to examine the inter‐rater reliability of classifying pressure ulcers according to the European Pressure Ulcer Advisory Panel classification system when using pressure ulcer photographs. Design. Survey was among pressure ulcer experts. Methods. Fifty‐six photographs were presented to 44 pressure ulcer experts. The experts classified the lesions as normal skin, blanchable erythema, pressure ulcer (four grades) or incontinence lesion. Inter‐rater reliability was calculated. Results. The multirater‐Kappa for the entire group of experts was 0.80 (P < 0.001). Various groups of experts obtained comparable results. Differences in classifications are mainly limited to 1 degree of difference. Incontinence lesions are most often confused with grade 2 (blisters) and grade 3 pressure ulcers (superficial pressure ulcers). Conclusions. The inter‐rater reliability of the European Pressure Ulcer Advisory Panel classification appears to be good for the assessment of photographs by experts. The difference between an incontinence lesion and a blister or a superficial pressure ulcer does not always seem clear. Relevance to clinical practice. The ability to determine correctly whether a lesion is a pressure ulcer lesion is important to assess the effectiveness of preventive measures. In addition, the ability to make a correct distinction between pressure ulcers and incontinence lesions is important as they require different preventive measures. A faulty classification leads to mistaken measures and negative results. Photographs can be used as a practice instrument to learn to discern pressure ulcers from incontinence lesions and to get to know the different grades of pressure ulcers. The Pressure Ulcer Classification software package has been developed to facilitate learning.     

Oh my,the pressure!

The intraoperative phase of a surgical patient's hospital stay has been overlooked as a major contributor of pressure ulcers that may arise postoperatively. Pressure ulcers are defined and then the hazards, underlying knowledge, and prevention tactics are reviewed. Bed sore, decubitous ulcer, pressure sore, and pressure ulcer are different terms describing the same problem encountered by medical and surgical patients. The common denominator is pressure--sustained pressure.     

Relationship of nursing personnel and nursing home care quality

The purpose of this study was to examine the associations between nurse staffing hours and 6 quality indicators: physical restraints, weight loss, incontinence, late loss activities of daily living decline, stages 1 to 4 pressure ulcers, and problem behaviors toward others. Increasing registered nurse staff hours may achieve better quality indicator scores for pressure ulcers. An increase in nurse aide hours should be carefully weighed with the amount of registered nurse staff time available for supervision and direction.     

Risk factors and prevention among patients with hospital-acquired and pre-existing pressure ulcers in an acute care hospital

Aims and objectives.  This study aimed to describe and identify risk factors associated with hospital‐acquired pressure ulcers among adults in an acute care hospital compared with patients with pre‐existing pressure ulcers present on admission. A further aim was to identify the preventive measures performed with both groups respectively. Background.  Pressure ulcers occur most often in older and immobile persons with severe acute illness and neurological deficits. However, few studies have addressed risk factors that are associated with hospital‐acquired pressure ulcers compared with patients with pre‐existing pressure ulcers. Design.  A point prevalence study with a cross‐sectional survey design was conducted at a Swedish university hospital. Method.  Data on 535 patients were recorded using a modified version of the protocol developed and tested by the European Pressure Ulcer Advisory Panel, including the Braden scale for risk assessment. Results.  The prevalence of pressure ulcers was 27% (95% confidence interval, 23–31%). Higher age and a total Braden score below 17 were significantly associated with the presence of pressure ulcers. Among individual risk factors higher age, limited activity level and friction and shear while seated or lying down were associated with hospital‐acquired pressure ulcers, whereas only higher age and friction and shear were associated with the presence of pressure ulcers in the overall sample. There was an overall sparse use of preventive measures to relieve pressure. Conclusion.  The findings of the present study revealed that pressure ulcers and the insufficient use of preventive measure to relieve pressure is still a problem in acute care settings. A continued focus must be placed on staff training in identifying patients at risk for pressure ulcers development. Relevance to clinical practice.  Increasing the ability to identify patients who are at risk for pressure ulcer development can assist in preventing unnecessary complications and suffering as well as reduce costs.     

Pressure ulcer incidence in Dutch and German nursing homes: design of a prospective multicenter cohort study

Background

Pressure ulcers are a common and serious health care problem in all health care settings. Results from annual national pressure ulcer prevalence surveys in the Netherlands and Germany reveal large differences in prevalence rates between both countries over the past ten years, especially in nursing homes. When examining differences in prevalence and incidence rates, it is important to take into account all factors associated with the development of pressure ulcers. Numerous studies have identified patient related factors, as well as nursing related interventions as risk factors for the development of pressure ulcers. Next to these more process oriented factors, also structural factors such as staffing levels and staff quality play a role in the development of pressure ulcers. This study has been designed to investigate the incidence of pressure ulcers in nursing homes in the Netherlands and Germany and to identify patient related factors, nursing related factors and structural factors associated with pressure ulcer development. The present article describes the protocol for this study.

Methods/design

A prospective multicenter study is designed in which a cohort of newly admitted nursing home residents in 10 Dutch and 11 German nursing homes will be followed for a period of 12 weeks. Data will be collected by research assistants using questionnaires on four different levels: resident, staff, ward, and nursing home.

Discussion

The results of the study will provide information on the incidence of pressure ulcers in Dutch and German nursing homes. Furthermore, information will be gathered on the influence of patient related factors, nursing related factors and structural factors on the incidence of pressure ulcers. The present article describes the study design and addresses the study's strengths and weaknesses.     

The prevalence of pressure ulcers in four paediatric institutions

Aim and objective. Pressure ulcers are a common nursing care issue in hospitals. They are associated with psychological and physical suffering, an increased morbidity and mortality rate and higher overall health care costs. The aim of the current study is to describe the frequency of pressure ulcers in a paediatric care setting and to identify the population at risk, as well as to assess the factors predisposing to the development of pressure ulcers. Design. A point prevalence study. Methods. The study was conducted in four paediatric hospitals in the German‐speaking part of Switzerland and included children from the age of 0–18 years. The method of data collection was a direct systematic inspection and assessment of the skin, taking into account the clinical condition of the patient for risk assessment. A valid risk assessment and data collection instrument was used and, each patient was assessed by a previously instructed rater pair. Results. Of all possible patients, 81% (n = 155) were included. An overall pressure ulcer prevalence of 27·7% (including grade 1) was registered. Thirty‐six patients (84%) had grade 1 ulcers, including many caused by external medical devices. Sixty‐five per cent (n = 100) of all patients were considered at risk (Braden score ≤ 20) of developing a pressure ulcer. Thirty‐five per cent of patients in the risk group were afflicted with one or more pressure ulcers. Conclusions. The prevalence of pressure ulcers in paediatric patients is greater then previously appreciated and the problem requires further exploration. The high percentage of grade 1 pressure ulcers caused by medical devices requires nursing interventions to prevent lesions for these patients. Relevance to clinical practice. The high prevalence rate in paediatric patients is disconcerting and requires further exploration in terms of interventions needed to improve outcomes for this patient group.
