OBJECTIVE To compare 2 wound volume measurement techniques, the Kundin device and stereophotogrammetry, on 2 wound shapes. DESIGN Using 2 wound measurement techniques, the interrater and intrarater reliability and the bias and standard error of measurement of an L-shaped and a pear-shaped plaster of paris wound model were assessed. SETTING A clinical laboratory of a school of nursing. PARTICIPANTS Twenty-four raters, all but 2 being registered nurses, measured each of the wounds using both techniques. INTERVENTIONS Each rater measured each wound twice using each method in a randomly assigned order defined on a card that was drawn from a box. Measurements were recorded on a researcher-designed data collection form, which included some demographic data related to each participant. MAIN OUTCOME MEASURES The study hypothesis was that there would be no significant difference in accuracy between the 2 wound volume measurement methods. RESULTS The least biased and most accurate technique was stereophotogrammetry, with the smallest standard of error of measurement. Interrater reliability of average ratings was identical for both methods at 0.98. For single ratings, stereophotogrammetry was slightly higher than the Kundin device. Intrarater reliability was higher on the pear-shaped wound for the Kundin device, which had lower interrater reliability, suggesting that nurses were consistent in the direction and size of personal error. Intrarater reliability for stereophotogrammetry was identical to that of the Kundin device for the L-shaped wound and lower for the pear-shaped wound. CONCLUSIONS Although both techniques have acceptable accuracy, stereophotogrammetry is more accurate and has more clinical applications.

In this descriptive, qualitative, phenomenological study, the researchers explored the phenomena of the lived experience of having a pressure ulcer to determine the essential structure of the experience. The sample included 8 respondents: 4 individuals who currently had a pressure ulcer and 4 who previously had a pressure ulcer that had healed. Four respondents also had a spinal cord injury and 5 had surgical flap reconstruction. Respondents were asked to reflect and reply to the following statements: "Please describe your experience of having a pressure ulcer. Share all the thoughts, perceptions, and feelings you can recall until you have no more to say about this experience." From verbatim transcriptions of interviews, 7 themes evolved with related sub-themes. The themes that emerged were (1) perceived etiology of the pressure ulcer; (2) life impact and changes; (3) psychospiritual impact; (4) extreme painfulness associated with the pressure ulcer; (5) need for knowledge and understanding; (6) need for and effect of numerous, stressful treatments; and (7) the grieving process. In this paper, the essential nature of the experience of living with a pressure ulcer is presented. Pressure ulcers had a profound impact upon the subjects' lives, including physical, social, and financial status; change of body image; and/or loss of independence and control. Those with a Stage IV pressure ulcer and flap repair and/or those with a spinal cord injury experienced the grieving process in some form. Although the experience of having a pressure ulcer has similarities for each individual, each experiences it in a unique manner. Patients with a pressure ulcer with or without a spinal cord injury have significant needs in learning to cope and live with their condition.

PURPOSE:The purposes of this study were to assess client comfort and sleep quality, client physiologic response (skin and respiratory status), the effect on the need for caregiver assistance, and cost when using an automated turning bed.DESIGN:Nonexperimental, evaluative study.SAMPLE:Twenty-four adult home or long-term care resident subjects who had a degenerative disease, spinal cord injury, stroke, cerebral palsy, or back surgery.METHODS:Each subject agreed to use the automated turning bed for four weeks. Researchers completed a demographic survey and skin assessment, and assessed each subject for pressure ulcer risk and for the need of assistance of a care giver for turning before and after the four weeks of using the turning bed. Subjects rated the turning bed in terms of comfort and sleep quality.FINDINGS:Subjects rated the turning bed as more comfortable than their own bed and expressed satisfaction at the pain relief attained when on the turning bed. While using the turning bed, there was a significant improvement in sleep quality. No skin breakdown or deterioration in respiratory status occurred. Fewer subjects required the assistance of a caregiver for turning when on the turning bed.CONCLUSION:This automated turning bed shows great promise in meeting a need for patients with limited mobility whether they are homebound or in a residential community.IMPLICATIONS FOR NURSING RESEARCH:Future studies that further investigate use of the turning bed for postoperative back patients while still in the acute care setting are indicated. Replicative studies with a larger sample size are also indicated.

Two- and three-dimensional wound measurement techniques are documented in the literature and used clinically, as well as in research. The purpose of this study was to compare 4 two-dimensional wound measurement techniques: linear length and width using a ruler, planimetry, computerized stereophotogrammetry (SPG) length and width, and computerized SPG area. Three plaster of Paris wound models were developed and baseline measurements of outer wound perimeters obtained via a Coordinate Measuring Machine. The convenience sample of raters included 66 upper-division baccalaureate nursing students, graduate nursing students, nursing staff, and wound care nurses. Each rater measured each wound twice in a randomly assigned order of methods written on a card drawn from an envelope. The least biased technique was the computer area, followed in order by the computer length and width, planimetry, and ruler length and width. The most accurate technique, given multiple raters, was determined by the standard error of measurement. The smallest standard error of measurement, thus the most accurate, was the computer area technique, followed in order by the ruler length and width, computer length and width, and planimetry. Interrater reliability of average ratings was high; only the SPG area measurements for single ratings were reliable enough for clinical or research purposes. Intrarater reliability was high for methods with low interrater reliability, suggesting that nurses are consistent in the direction of personal error.

Home care patients either have or are at high risk for pressure ulcers. This article describes the outcome of a study that examined the effects of pressure ulcer prevention and treatment standards on the prevalence rate of a home healthcare agency's client caseload. Implications for practice and further research also are discussed.

The purpose of this prospective study was to determine the incidence of pressure ulcers and to examine factors related to pressure ulcer development in patients in an acute care setting. Adult medical and surgical patients who were free of pressure ulcers at admission were assessed within 36 hours of admission and then three times per week for 2 weeks or until discharge. Instruments included a demographic data form, a skin assessment form, and the Braden Scale for Predicting Pressure Sore Risk. Most subjects had 46 assessments completed. The sample consisted of 149 subjects, with a pressure ulcer incidence rate of 13.4% (n = 20). Subjects who acquired pressure ulcers had lower hemoglobin levels (t = 2.17, p = 0.03), spent more time in bed (t = 3.90, p = 0.0001), and spent less time in a chair (t = 3.2, p = 0.002) than those who did not acquire pressure ulcers. A stepwise logistic regression analysis was used to calculate risk of pressure ulcer development. In the final model, hemoglobin level and hours spent in bed continued to be predictors of pressure ulcer development (chi 2 = 9.306, df = 2, p = 0.0095). All 20 subjects who acquired pressure ulcers were further categorized into groups with stage I (n = 12) or stage II (n = 8) ulcers. Patients with stage I pressure ulcers were primarily receiving post-surgical care (67%), whereas patients who acquired stage II ulcers had medical conditions that affected tissue perfusion, such as respiratory diseases (50%) and diabetes mellitus (12%).

Pressure ulcers (PU) remain a serious healthcare problem in the United States. This study investigated the effectiveness of a prevention and early intervention program in reducing the prevalence of pressure ulcers (i.e., the number or the percentage of persons with pressure ulcers at a given time) in a rehabilitation hospital. The Braden Scale for Predicting Pressure Sore Risk was used to assess subjects' PU risk. Protocols were established for PU stages consistent with the National Pressure Ulcer Advisory Panel consensus statement on pressure ulcers. Staff were educated about PUs and the specific protocols for prevention and treatment. Concurrent quarterly prevalence audits on a total of 116 patients were conducted for 1 year. An audit also was done 16 months after protocols had been established. There was a 60% decrease in pressure ulcer prevalence from the 25% baseline to the 10% found at the audit following implementation of the protocols.

1. Pressure ulcers continue to be a serious problem in nursing home settings. They are significant as a source of discomfort and disability among nursing home residents, as well as a source of financial concern for the institutional agencies responsible for resident care. 2. Prevention and intervention at the earliest stages of pressure ulcer development offer the most effective approaches to mediating the human and economic costs imposed by pressure ulcers. 3. Strategies that are effective in reducing both the development and severity of pressure ulcers can be successfully implemented in long-term care settings. Further studies are needed that will provide additional support for the strategies and protocols used in this study.

Hospice patients may be particularly at risk for pressure ulcer development due to several factors. Identifying populations at risk for pressure ulcer development, such as hospice patients, and providing prevention and risk protocols for these populations can substantially reduce the prevalence and incidence of pressure ulcers. However, are hospice patients prone for skin breakdown despite prevention and treatment efforts? This study examines the prevalence of pressure ulcers in hospice patients following the implementation of pressure ulcer prevention and treatment protocols. Levine's theory of conservation of structural integrity formed the theoretical framework for this descriptive study. A midwestern hospital-based hospice agency was the site for this study. All patients 18 years of age and older were included in the study. Pressure ulcer prevalence audits were done at four, eight, 12, and 18 months after protocols were outlined by the hospice staff. Results of the audits revealed prevalence rates of 14.8 percent, 8.5 percent, 13.6 percent, and 23.8 percent, at each of the aforementioned audits. 10 of 15 patients who were pressure ulcer positive were males; the sacral location was most common (seven of 19 ulcers occurred sacrally) with the ischial location being the next common (six of 19 ulcers were ischially located). No ulcers occurred above the waist or in patients below 51 years of age. Recommendations from this study urge that particular prevention attention be given to protocols which address "sitting," due to the predominance of ulcers located in the sacral and ischial regions. In addition, the author concludes that perhaps, pressure ulcers may occur in this population despite the best of efforts to prevent them.

With the earlier discharge from the acute care setting, there may be an increased suscep tibility to the development of pressure ulcers in the home than ever before. A descriptive study was undertaken to determine pressure ulcer prevalence and incidence prior to in stituting prevention and treatment protocols. Study findings are presented in this article.

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.

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.

Pressure ulcers (PU), one example of an alteration in skin integrity, remain a prominent healthcare concern in all patient care settings. Incidence refers to the number of "new cases occurring over a given time period" (NPUAP, 1989, p. 26). Adult patients (n = 190) in five patient care settings who were assessed to be free of PUs on admission were followed over a specified period of time to assess the incidence of pressure ulcer development for each setting. Subjects each had a skin assessment, along with a risk assessment utilizing the Braden Scale. A demographic data form was also completed on each subject. Pressure ulcers developed post-admission in 18 (9%) patients, 11 of whom were acute care patients and eight of whom were patients in skilled care. No patients developed pressure ulcers in the rehabilitation, home care, or hospice settings. Incidence for acute care was 15% and 28% in skilled care. Braden predictor scores were also recommended for each setting and factors associated with pressure ulcer development were discussed.

Hospice patients may be at greater risk of pressure ulcer development than most patients. This descriptive study explored the prevalence and incidence of pressure ulcers in the hospice setting, utilizing both a prospective and retrospective methodological approach. Levine's theory of the four principles of conservation formed the theoretical basis for the study, and the Braden Scale for Predicting Pressure Ulcer Risk was used for data collection. Prevalence of pressure ulcers was noted to be 13 percent in the study. Incidence of pressure ulcers was found to be zero percent using prospective methodology and 13 percent using retrospective methodology. Five of eight ulcers (62 percent) occurred with Ain two weeks of patient death. Factors related to pressure ulcer development are presented, as well as a discussion of using research methodologies in the hospice setting. The article suggests the need for preventive protocols for skin care for patients who are at risk for pressure ulcer development.
