Pressure sore prevalence: a national survey

? A cross-sectional nation-wide sample was used to determine the point prevalence and grading of pressure sores in patients in all hospitals in Iceland (22 hospitals). ? The pressure sore prevalence was 8.9% (n = 57 patients), 7.12% for women (n = 26) and 11.2% for men (n = 31); the mean age for both sexes with pressure sores was 78.4 years. ? Grade I sores were most frequently identified and Grade IV the least. Eighty-five per cent of pressure sores were located below the waist. ? `No dressings' and occlusive dressings were the treatment of choice for pressure sores. ? Results from this study are important for international comparisons.     

A clinical trial of the Braden Scale for Predicting Pressure Sore Risk

The purpose of this article was to describe the protocol by which predictive instruments can be tested for validity and to evaluate the usefulness of an instrument for predicting pressure sore risk in an AICU. The Braden Scale for Predicting Pressure Sore Risk was described. Methods for measuring predictive validity and for calculating sensitivity, specificity, and per cent predictive value of positive and negative tests were discussed. Sixty consecutively admitted AICU patients who were pressure sore free were rated for pressure sore risk within 24 to 72 hours after admission. The skin condition of each patient was systematically assessed every 2 days. Twenty-four subjects developed pressure sores during the study period. The critical cut-off point at which the patient could be judged to be at risk for pressure sore formation was a Braden Scale score equal to or less than 16. The sensitivity and specificity of the scale at this score were 83 to 64 per cent, respectively. The per cent predictive value of a positive and negative test were 61 and 85 per cent, respectively. The Braden Scale compared favorably with the Norton Scale in respect to sensitivity. The specificity, or the tendency of a scale to overpredict, was greater for the Norton than for the Braden Scale. The Norton Scale overpredicted by 64 per cent, whereas the Braden Scale overpredicted by 36 per cent. This difference may be important clinically if all patients who were judged to be at risk received additional nursing care or protective devices. A greater number of patients may receive unnecessary and expensive treatments using the Norton Scale.     

An analysis of epidural related pressure sores in a specific patient population

The objective of this study was to investigate the relationship between post-operative epidural analgesia and incidence of heel pressure sores. The study sample consisted of 53 men and women over the age of 20 years who had major abdominal surgery (mean age 69 years). The main outcome measure was the number of patients who developed any degree of heel sore in the post-operative period. Pressure sore risk assessments were completed by the general surgical nurses with grade of risk recorded. Twenty-one percent of patients in the study developed pressure changes on the skin of their heels; 5.7% developed changes of Grade 2 or worse. Only 10 patients (18.9%) were scored as being at high risk of pressure sores post-operatively. Fifteen (28.3%) patients had no pressure sore risk assessment carried out post-operatively. Ward staff failed to recognise that their patients had been placed at high risk by the use of epidural analgesia post-operatively.     

The Use of the Modified Norton Scale in Nursing-Home Patients

Patients in three nursing-home wards in Sweden were in 1991 assessed by the Modified Norton Scale (MNS). Of the 71 patients, 38 (49%) were considered to be at risk of developing pressure sores. Six of the patients had a total of eight pressure sores. Five sores were assessed as stage II, two sores as stage III and one sore as stage IV. Only two of the six patients with pressure sores had any preventive equipment in their beds. The nursing and medical documentation of the existing pressure sores was not satisfactory. Individual programs for skin care and routine assessment with a pressure sore prediction instrument, such as the MNS, would serve the dual purpose of directing the relevant measures to the patient groups at the greatest risk and would aid in assessing the efficacy of pressure sore treatment strategies.     

Logistic Regression Analysis and Nursing Interventions for High-risk Factors for Pressure Sores in Patients in a Surgical Intensive Care Unit

Objective:To investigate the risk factors related to the development of pressure sores in critically ill surgical patients and to establish a basis for the formulation of effective precautions.Methods:A questionnaire regarding the factors for pressure sores in critically ill surgical patients was created using a case control study with reference to the pertinent literature.After being examined and validated by experts,the questionnaire was used to collect data about critically ill surgical patients in a grade A tertiary hospital.Among the 47 patients enrolled into the study,the 14 who developed nosocomial pressure sores were allocated to the pressure sore group,and the remaining33 patients who met the inclusion criteria and did not exhibit pressure sores were allocated to the control group.Univariate and multivariate logistic regression analyses were employed to examine the differences in22 indicators between the two groups in an attempt to identify the risk factors for pressure sores.Results:According to the univariate analyses,the maximum value of lactic acid in the arterial blood,the number of days of norepinephrine use,the number of days of mechanical ventilation,the number of days of blood purification,and the number of days of bowel incontinence were statistically greater in the pressure sore group than in the control group(P0.05).The multivariate logistic regression analysis revealed that the number of days of norepinephrine use and the level of lactic acid in the arterial blood were high risk-factors for pressure sores(P0.05).Conclusions:The best method for preventing and control pressure sores in surgical critically ill patients is to strongly emphasize the duration of the critical status and to give special attention to patients in a continuous state of shock.The adoption of measures specific to high-risk patient groups and risk factors,including the active control of primary diseases and the application of decompression measures during the treatment of the patients,are helpful for improving the quality of care in the prevention and control of pressure sores in critically ill patients.     

Monitoring the pressure sore problem in a teaching hospital

During 1989 and 1990 a senes of three prevalence surveys were undertaken in a West Midlands teaching hospital to identify the numbers of patients at risk of developing pressure sores and the actual number of patients with pressure sores, prior to the purchase of pressure relieving equipment A further survey was undertaken in January 1993 to examine any improvement in pressure sore prevention strategies and in the care of those with established pressure sores All in-patients were assessed using the Waterlow score Full details of all pressure sores and any pressure relieving equipment in use was recorded The findings were compared with those of the first survey in 1989 The prevalence for 1989 was 8 77%, and this had reduced slightly to 7 9% in 1993 There was no significant difference in these figures However, in 1989 35 patients had 64 pressure sores and in 1993 32 patients had 46 pressure sores There was a significant reduction in the actual numbers of pressure sores There was no significant difference in the grades of sores and the sacrum was the most frequent position in both surveys The survey showed an improvement in the management of established pressure sores There was little change in the patient populations with respect to the degree of risk of pressure sore development Using the Waterlow score, the numbers of patients found to be in the no risk, at risk, high risk and very high risk categories remained remarkably stable These surveys will continue to provide a basis for selecting pressure relieving equipment Measurement of pressure sore incidence is needed in the future to monitor the efficacy of the prevention programme     

La escala APACHE III: un factor pronóstico en la aparición de úlceras por presión en una Unidad de Cuidados Intensivos

ObjectiveTo analyze total APACHE III score association to pressure ulcers development in patients hospitalized in an intensive care unit (ICU).Material and methodsProspective cohort study conducted in an intensive care unit of the Hospital General de VIC. All the patients hospitalized between January 2001 to December 2001 were enrolled. Age, gender, length of stay, total Norton and APACHE III score and pressure sore development were collected.ResultsPressure sore incidence was 12.5% of the patients. The factors were significantly associated with the appearance of pressure sores in those patients with a length of stay in the intensive care unit, total Norton and severity of the disease measured by the APACHE III score. Patients having the greatest risk of pressure ulcers development were those whose Norton score was less than or equal to 14, and an APACHE III score higher than or equal to 50 (Odds Ratio: 37.9, 95% CI 11.16-128.47)ConclusionThe severity of the diseases measured with the APACHE III scale showed a relationship with the appearance of in-hospital pressure ulcers.The joint use of the APACHE III and Norton scale could be a good strategy to detect patients with very high risk of suffering pressure sores.     

The surveillance system of decubital lesions of the University Polyclinic in Udine: results of an incidence study

A retrospective study of the incidence of pressure sores was one of the principal component of the ad hoc program of surveillance, prevention and treatment of pressure sores started in 1996 at University Hospital of Udine. Data were collected from the nursing records of patients defined at risk according to the Waterlow scale and admitted during 1998-99. Aims of the study were to quantify the number of patients who developed a pressure sore while in hospital and their risk level; stage of the lesions; to qualify the main risk factors and the management strategies adopted (i.e. mattresses, medications). Overall, 151 subjects (20.7% of those recruited) developed a pressure sore the greatest majority (96%) were classified as transient and reactive redness or superficial sore, while 14 patients (4%) developed a severe sore. For 50.4% of the lesions a regression to a lower risk level or healing were documented.

A risk assessment scale for the prediction of pressure sore development: reliability and validity

BACKGROUND: The ability to assess the risk of a patient developing pressure sores is a major issue in pressure sore prevention. Risk assessment scales should be valid, reliable and easy to use in clinical practice. AIM: To develop further a risk assessment scale, for predicting pressure sore development and, in addition, to present the validity and reliability of this scale. METHODS: The risk assessment pressure sore (RAPS) scale, includes 12 variables, five from the re-modified Norton scale, three from the Braden scale and three from other research results. Five hundred and thirty patients without pressure sores on admission were included in the study and assessed over a maximum period of 12 weeks. Internal consistency was examined by item analysis and equivalence by interrater reliability. To estimate equivalence, 10 pairs of nurses assessed a total of 116 patients. The underlying dimensions of the scale were examined by factor analysis. The predictive validity was examined by determination of sensitivity, specificity and predictive value. RESULTS: Two variables were excluded as a result of low item-item and item-total correlations. The average percentage of agreement and the intraclass correlation between raters were 70% and 0.83, respectively. The factor analysis gave three factors, with a total variance explained of 65.1%. Sensitivity, specificity and predictive value were high among patients at medical and infection wards. CONCLUSION: The RAPS scale is a reliable scale for predicting pressure sore development. The validity is especially good for patients undergoing treatment in medical wards and wards for infectious diseases. This indicates that the RAPS scale may be useful in clinical practice for these groups of patients. For patients undergoing surgical treatment, further analysis will be performed.     

The clinical relevance of the waterlow pressure sore risk scale in the ICU

Objective: To evaluate whether the Waterlow pressure sore risk (PSR) scale has prognostic significance for intensive care patients. Design: A prospective study. Setting: The surgical intensive care unit (ICU) of the University Hospital Rotterdam. Patients: Data were evaluated from 594 patients who had been admitted to the ICU during the year 1994. Methods and results: Each patient was assessed daily with respect to their Waterlow PSR score and the development of pressure sores in the sacral region. Actuarial statistical methods were used to analyse the predictive value of the risk score. When a patient had a Waterlow PSR score > 25 on admission, the risk of developing a pressure sore was significantly increased compared to patients with a PSR score < 25. After admission, the daily Waterlow PSR scores obtained were significantly associated with the risk of developing a pressure sore. For each additional point this risk increased by 23 % (95 % confidence interval 17 to 28 %). Conclusions: The Waterlow PSR scale provides the medical and nursing staff at an early stage with reliable information about the risk patients have in developing a pressure sore.

Validity and reliability of the braden scale and the influence of other risk factors: a multi-centre prospective study

The Braden scale is one of the most intensively studied risk assessment scales used in identifying the risk of developing pressure sores. However, not all studies show that the sensitivity and specificity of this scale is sufficient. This study, therefore, investigated whether adding new risk factors can enhance the sensitivity and specificity of the Braden scale. The Braden scale was tested in a prospective multi-centre design. The nurses of 11 wards filled in the Braden scale every 5 days for each patient who was admitted without pressure sores and who had a probable stay of at least 10 days. Based on a literature study and in-depth interviews with experts, the Braden scale was extended by the risk factor blood circulation. In addition, other risk factors, which are more or less stable patient characteristics, were measured during the admission of the patient. Independent research assistants measured the presence of pressure sores twice a week. As the external criterion for the risk of developing pressure sores, the presence of pressure sores and/or the use of preventive activities was used. Results showed that the original Braden scale was a reliable instrument and that the sensitivity and specificity was sufficient. However, reformulating the factors moisture and nutrition, and adding the risk factor age could enhance the sensitivity and specificity. Furthermore, results showed that the factors sensory perception, and friction and shear were especially important risk factors for the Braden scale. In fact, using only the factors sensory perception, friction and shear, moisture (a reformulated factor) and age give the highest explained variance of the risk of developing pressure sores. The added risk factor blood circulation, did not enhance the sensitivity and specificity of the original Braden scale. Suggestions are given on how to use risk assessment scales in practice.

Paraplegic pressure sore frequency versus circulation measurements

Paraplegic subjects (N = 34) were examined to determine the association of pressure sore history with respect to ankle pressure ratio and buttocks cutaneous plethysmographic harmonic persistence. No relationship was found between pressure sore history and ankle pressure ratio. No significant difference in ankle pressure ratios exists for those who have a pressure sore history as compared to those who have not experienced a pressure sore in 5 years. Those subjects with a diminished buttocks circulation harmonic persistence are more likely to have experienced one or more pressure sores than those subjects with normal circulation characteristics. A Poisson distribution analysis of multiple pressure sore occurrence suggests that repeated pressure sores are unlikely to arise as the result of chance.
