An instrument to measure healing in pressure ulcers: development and validation of the pressure ulcer scale for healing (PUSH).

BACKGROUND: Currently, there is no instrument that provides an accurate and simple method of monitoring pressure ulcer healing in clinical practice. This article reports the two studies that were conducted to assess the validity of the Pressure Ulcer Scale for Healing (PUSH) as a tool to monitor healing of stage II-IV pressure ulcers. METHODS: Subjects in both studies (N = 103 and N = 269) were elderly (mean Study 1, 75 years, mean Study 2, 80 years), and the majority were women (Study 1, 51%, Study 2, 70%). Study data were extracted from patients' permanent records. RESULTS: Principal components analysis confirmed that the PUSH tool accounted for 58% to 74% of the wound healing variance over a 10-week period in Study 1 and 40% to 57% of the wound healing variance over a 12-week period in Study 2. In addition, multiple regression analysis, used to measure the sensitivity of the model to total healing, showed PUSH accounted for 39% of the variance in 6 weeks and 31% of the variance over 12 weeks (p <.001; Studies 1 and 2, respectively). CONCLUSIONS: Data from these two studies confirmed that the PUSH tool, with the components of length times width, exudate amount, and tissue type, is a valid and sensitive measure of pressure ulcer healing. It is a practical approach that provides clinically valid data regarding pressure ulcer healing. Further testing is needed to confirm these findings.

The Geriatric Pain Measure: validity, reliability and factor analysis.

BACKGROUND: Pain is a multidimensional experience that should be evaluated beyond an estimate of intensity. A multidimensional pain measure has not been developed for older persons undergoing comprehensive geriatric assessment. OBJECTIVE: To develop and evaluate validity and reliability of a multidimensional pain assessment instrument for older persons. RESEARCH DESIGN: A series of steps in instrument development and evaluation. SUBJECTS: A total of 176 subjects (mean age 84 +/- 6.0 years) in ambulatory geriatric clinics; 64% were women, and 73% had a history of chronic pain. MEASUREMENTS: Measurements included the Geriatric Pain Measure (GPM), the McGill Pain Questionnaire, Yesavage GDS, Katz ADLs, Lawton IADLs, Tinetti Gait and Balance, Folstein MMSE, and other demographic and clinical characteristics from interview and chart review. RESULTS: The GPM demonstrated a standardized alpha = 0.9445, homogeneity ratio =0.457, and average inter-item correlation =0.415. A subgroup of 50 subjects demonstrated concurrent validity of the GPM in comparison with the McGill Pain Questionnaire (Pearson's r correlation 0.6269 (P < .0000). Test-retest reliability was demonstrated in another subgroup of 50 subjects who repeated the GPM within 48 to 72 hours (Pearson's r = 0.9018; P < .0000). Factor analysis revealed five clusters of components: Pain Intensity, Disengagement, Pain with Ambulation, Pain with Strenuous Activities, and Pain with Other Activities. CONCLUSIONS: The GPM is a 24-item questionnaire that is easy to administer and has significant validity and reliability in older persons with multiple medical problems. The GPM may be a useful addition to the multidimensional geriatric assessment process.

Pain management.

Pain is a common problem encountered among elderly people in subacute and long-term care facilities. Pain often is underestimated and undertreated in these settings. Most pain problems can be improved by careful assessment and careful use of analgesic drugs and nondrug strategies. Subacute care and other long-term care facilities often present unique challenges to pain management. Clinicians who care for patients in these settings must help to establish a plan of care that is reasonable for the given resources and skills often available in these settings. Clinicians have an obligation to improve comfort and dignity for these patients, especially those near the end of life.

Pressure ulcers among patients admitted to home care.

CONTEXT: Pressure ulcers are an understudied problem in home care. OBJECTIVE: To determine the prevalence of pressure ulcers among patients admitted to home care services, describe the demographic and health characteristics associated with pressure ulcers in this setting, and identify the percentage of these patients at risk for developing pressure ulcers. DESIGN: Cross-sectional survey of patients on admission to home care agencies. SETTING: Forty-one home care agencies in 14 states. PATIENTS: A consecutive sample of 3,048 patients admitted March 1 through April 30, 1996 (86% of all admissions). Subjects had a mean age of 75 years; 63% were female and 85% white. MAIN OUTCOME MEASURES: Demographic, social, and clinical characteristics, functional status (Katz activities of daily living scale and Lawton instrumental activities of daily living scale), mental status (Katzman Short Memory-Orientation-Concentration test), pressure ulcer risk (Braden Scale), pressure ulcer status (Bates-Jensen Pressure Ulcer Status Tool), and a checklist of pressure-reducing devices and wound care products being used. RESULTS: In the total sample of 3,048 patients, 9.12% had pressure injuries: 37.4% had more than one ulcer and 14.0% had three or more ulcers. Considering the worst ulcer for each subject, 40.3% had Stage II and 27% had Stage III or IV injuries. Characteristics associated with pressure ulcers included recent institutional discharge, functional impairment, incontinence, and having had a previous ulcer. About 30% of subjects were at risk for new pressure ulcers. Pressure-relieving devices and other wound care strategies appeared to be underutilized and often indiscriminately applied. CONCLUSIONS: There is substantial need for pressure ulcer prevention and treatment in home care settings.

Fatigue in an older population.

OBJECTIVES: Fatigue is a common symptom that has not been studied well in the older populations. The purpose of this pilot study was to examine the epidemiology of fatigue symptoms in relation to demographic and medical characteristics of older patients in a long-term care setting. DESIGN: A cross-sectional interviewer-assisted survey. PARTICIPANTS/SETTING: A total of 199 ambulatory older residents of a single residential care facility. MEASUREMENTS: Along with medical and demographic characteristics, the survey included mental status (Folstein), activities of daily living (Katz and Lawton), depression (Yesavage GDS), a 3-minute walk, a 7-item pain scale, and the modified Piper Fatigue Scale. RESULTS: One-hundred ninety-nine (65%) of 308 potential subjects completed the study (mean age 88 years, 82% female). Of these 199 subjects, 195 (98%) reported some fatigue symptoms (median duration 44 weeks). Significant (P < .0005) relationships were found between fatigue and GDS (r = 0.57), 3-minute walk (r = -0.29), Lawton IADLs (r = 0.31), pain (r = 0.36), and number of medications (r = 0.26). No significant relationships were found between fatigue and age, sex, Folstein score, or number of medical diagnoses. Multivariate regression analysis identified GDS, pain, number of medications and 3-minute walk as significant predictors of fatigue intensity (multiple R = 0.68, r2 = 0.46, P < .02). CONCLUSIONS: Fatigue is a symptom often found among older residents of a residential facility and has important implications for quality of life. Fatigue is poorly recognized and probably undertreated in older people.

The Sessing Scale for measurement of pressure ulcer healing.

Measurement of healing is an essential aspect of pressure ulcer management. This paper provides a review of the Sessing Scale for measurement of pressure ulcer healing. The Sessing Scale is a seven-point observational scale anchored by verbal descriptions of wound healing. It is a simple, easy-to-use instrument with demonstrated validity and reliability for the measurement of healing. Findings indicate that with descriptions of granulation tissue, infection, necrosis, and eschar, the instrument measures an important domain of healing independent of wound size or depth.

Pressure ulcer scale for healing: derivation and validation of the PUSH tool. The PUSH Task Force.

Measuring progress toward healing is fundamental to the management of pressure ulcers. A method to assess progress of an individual ulcer over time is lacking. Given the limitations of currently available instruments and the need for a precise and practical method of monitoring healing in clinical practice, the National Pressure Ulcer Advisory Panel initiated the development of a new tool for measuring pressure ulcer healing. The key elements in developing an instrument include simplicity of use in clinical settings, validity for measuring whether ulcers are improving or worsening, and sensitivity to changes in the ulcer between observations. A new tool incorporating surface area, exudate amount, and surface appearance is proposed. Content validity, correlation validity, prospective validity, and sensitivity to change can be met by the proposed Pressure Ulcer Scale for Healing instrument.

Pressure ulcers. Assessment of healing.

Assessment of pressure ulcer healing involves observation during a complex series of cellular and molecular events that result in repair and restoration of skin integrity and function. Although the most important endpoint in healing is complete wound closure, it may not be a practical measurement in most settings. Assessment, therefore, often relies on measurement of partial healing, including changes in size and other wound characteristics over time. With no consensus about the best method for measurement of healing, it is not surprising that rates of healing have been described in only a few research studies. The establishment of a universal method for wound healing measurement is needed urgently.

A randomized trial of walking versus physical methods for chronic pain management.

We conducted a pilot study to evaluate a practical exercise program for elderly people with chronic musculo-skeletal pain. Thirty-three subjects (mean age, 73 years; 69% back pain; 24% knee pain; 9% hip pain) were randomly assigned to one of three groups. Group 1 received 6-week supervised program of walking. Group 2 received a pain education program that included instruction and demonstration of use of heat, cold, massage, relaxation and distraction. Group 3 received usual care. Outcomes including pain, self-reported health and functional status, and performance-based measures of functional status were evaluated at baseline, at two weeks and at eight weeks (end of study). Attendance was 100% for the education sessions and 93% for walking sessions. No injuries were sustained. Both intervention groups demonstrated significant improvements in pain (p < 0.05) and performance-based measures of functional status (p < 0.05), while the control group had no changes. These data suggest that patient education and fitness walking can improve overall pain management and related functional limitations among elderly people with chronic musculo-skeletal pain.

Pain in the nursing home.

The treatment of pain in the nursing home setting is a unique and challenging problem. Studies of the prevalence of pain in this setting have been limited, and many of the assessment tools used routinely with younger adults have not been validated in this population. The application of pharmacologic interventions is more difficult because of the higher incidence of side effects in the elderly, as well as the limited resources and logistical issues often encountered in the nursing home. This article explores these issues and offers suggestions for the appropriate management of pain in the long-term care resident.

Pain evaluation and management in the nursing home.

As many as 45% to 80% of nursing home residents have pain that contributes materially to functional impairment and decreased quality of life. Substantial barriers, including a high frequency of dementia, multiple pain problems, and increased sensitivity to drug side effects often make pain assessment and management more difficult in the nursing home setting. Logistic problems in carrying out diagnostic procedures and management interventions are also common. Pain can be alleviated in nursing homes through the careful use of analgesic drugs combined with nonpharmacologic strategies, including exercise programs and other physical therapies. Elderly nursing home residents are more sensitive to the side effects associated with many analgesic drugs, but this does not justify the failure to treat pain, especially in those who are terminally ill or near the end of life. Structured programs for routine pain assessment and treatment are needed. Physician involvement in pain assessment and management is necessary if pain control is to be improved for nursing home patients.

Pain in cognitively impaired nursing home patients.

Pain is an understudied problem in frail elderly patients, especially those with cognitive impairment, delirium, or dementia. The focus of this study was to describe the pain experienced by patients in skilled nursing homes, which have a high prevalence of cognitive impairment. A random sample of 325 subjects was selected from ten community skilled nursing homes. Subjects underwent a cross-sectional interview and chart review for the prevalence of pain complaints, etiology, and pain management strategies. Pain was assessed using the McGill Pain Questionnaire and four unidimensional scales previously utilized in younger adults. Thirty-three percent (33%) of subjects were excluded because they were either comatose (21%), non-English speaking (3.7%), temporarily away (sick in hospital) (4.3%), or refused to participate (3.7%). Of 217 subjects in the final analysis, the mean age was 84.9 years, 85% were women, and most were dependent in all activities of daily living. Subjects demonstrated substantial cognitive impairment (mean Folstein Mini-Mental State exam score was 12.1 +/- 7.9), typically having deficits in memory, orientation, and visual spatial skills. Sixty-two percent reported pain complaints, mostly related to musculoskeletal and neuropathic causes. Pain was not consistently documented in records, and pain management strategies appeared to be limited in scope and only partially successful in controlling pain. None of the four unidimensional pain-intensity scales studied in this investigation had a higher completion rate than the Present Pain Intensity Scale of the McGill Pain Questionnaire (65% completion rate). However, 83% of subjects who had pain could complete at least one of the scales. We conclude that cognitive impairment among elderly nursing home residents present a substantial barrier to pain assessment and management. Nonetheless, most patients with mild to moderate cognitive impairment can be assessed using at least one of the available bedside assessment scales.

The impact of cancer pain education on family caregivers of elderly patients.

PURPOSE/OBJECTIVES: To examine the impact of pain education on family members providing home care to elderly patients with cancer. DESIGN: Quasiexperimental. SETTING: Homes of selected patients from two California medical centers. SAMPLE: Fifty family caregivers of patients experiencing cancer-related pain. METHODS: The pain education program included three components: pain assessment, pharmacologic interventions, and nonpharmacologic interventions. Patients and their family caregivers were evaluated prior to initiation of the program and at one and three weeks following the interventions. MAIN RESEARCH VARIABLES: Quality of life (QOL); knowledge and attitudes about pain; and caregiver burden. FINDINGS: Findings based on measures of QOL and caregiver burden demonstrated the physical and psychological impact of family caregiving and pain management. Comparison between elderly patients with cancer and family caregivers revealed the pain experience's significant impact on family members caring for a loved one in pain. CONCLUSIONS: The pain education program was effective in improving knowledge and attitudes regarding pain management. IMPLICATIONS FOR NURSING PRACTICE: Pain management is a priority for nurses, and use of interventions such as structured pain education improves QOL outcomes for elderly patients and their family caregivers.

Cost-effectiveness of low-air-loss beds for treatment of pressure ulcers.

BACKGROUND: Cost-effectiveness of low-air-loss beds for the healing of pressure ulcers was analyzed in the nursing home setting. A statistical model of pressure ulcer healing was used to estimate cost-effectiveness based on patient and ulcer characteristics. METHODS: Results of a previous randomized trial (84 patients from three nursing homes in Los Angeles) were reanalyzed and combined with estimates of costs to calculate the cost-effectiveness in dollars per added day free of pressure ulcers achieved by the use of low-air-loss beds compared to conventional foam mattresses. RESULTS: The cost-effectiveness of the low-air-loss bed was $26 per added day free of ulcers for our standard patient. Results were sensitive to low-air-loss bed lease costs and patient and wound healing characteristics. Results were less sensitive to expected mortality, daily wound care costs, and time-frame of consideration. Low-air-loss beds were more cost-effective for patients with good healing characteristics and mild ulcers. CONCLUSIONS: Findings support the expanded use of this technology for patients with mild pressure ulcers and good healing characteristics. For these patients, the cost-effectiveness of low-air-loss beds is comparable to other accepted health treatments. For patients with severe ulcers and poor healing characteristics, low-air-loss bed cost-effectiveness compares poorly with other accepted health treatments unless the lease cost can be substantially reduced, or unless life with a pressure ulcer is valued close to death.

The Sessing scale for assessment of pressure ulcer healing.

OBJECTIVE: To describe a new observational scale, the Sessing scale, for measuring the progression of pressure ulcers. CRITERION STANDARDS: Changes in Shea stage and the diameter of healing pressure ulcers. SUBJECTS: A cohort of 84 nursing home residents with pressure ulcers. RESULTS: There were strong relationships between changes in healing as measured by the Sessing Scale and those measured by the Shea Scale (Spearman's r = 0.90; P < .0001), and between changes in the Sessing scale compared with changes in ulcer diameter (Spearman's r = 0.64; P < .001). Test-retest reliability was good (Kappa = 0.84) in a sample of 50 subjects. CONCLUSION: The Sessing scale is a simple, easy to use, observational instrument with validity and reliability for the assessment of progression of pressure ulcers in a clinical or research setting. Findings indicate that the Sessing scale, with its description of granulation tissue, infection, drainage, necrosis, and eschar, measures an important domain of wound healing that is independent and perhaps as important to clinicians and researchers as either Shea stage or ulcer size.

Pain management for elderly patients with cancer at home.

BACKGROUND: Pain is an important problem for patients with cancer and is particularly important for elderly patients with cancer and their family care givers. Increasingly, cancer is managed on an outpatient basis with pain management responsibility assumed by the family at home. This study evaluated a structured pain education program that included three components: basic pain management principles and assessment, pharmacologic interventions, and nondrug treatments. METHODS: The pain education intervention was implemented across three home visits with two points of follow-up evaluation. Outcomes of the 66 elderly patients with cancer completing the educational program included measures of quality of life, patient knowledge and attitudes regarding pain, and use of a self-care log to document drug and nondrug interventions and their effectiveness. RESULTS: Repeated measurement analysis was used to evaluate the outcomes of the three-part education intervention. Results indicate an improvement in knowledge and attitudes regarding pain as well as the use of drug and nondrug interventions. Outcomes of the quality of life instrument suggest significant effect of pain on all aspects of quality of life, including physical well being, psychological well being, social concerns, and spiritual well being. CONCLUSIONS: The investigators concluded that the pain education intervention provided important support to elderly patients with cancer and family members at home. Structured pain education based on an evolving science of pain relief should become a part of the standard health care for pain management. Improved pain management includes quality of life for the elderly patient with cancer as well as for family care givers.

Development and implementation of a pain education program.

Pain is a significant problem for cancer patients and is of particular concern for the elderly. This article reports on the development and implementation of a pain management educational intervention for elderly cancer patients and their family caregivers. This patient education program was developed within a research study funded by the American Cancer Society. Subjects were stratified as either elderly (60-75 years) or oldest (greater than 75 years) and then were randomly assigned to an experimental group that received the three-part, structured pain education program or a control group that received usual care. Control group subjects were offered the intervention at the conclusion of data collection. The outcomes of the pain education were measured at two times after the intervention. Study variables included patient outcomes such as pain intensity, pain knowledge and attitudes, medication compliance, and quality of life as well as family caregiver outcomes. This pain education program was developed, implemented, and evaluated in 40 patients and family caregivers in the first year of a 2-year project. In this article, the investigators present the development and structure of the three-part education program, general principles of patient education regarding pain, methods of evaluating pain education, and initial results of the pain education. Pain education includes basic principles of pain relief, pharmacologic interventions, and nondrug interventions for relief of pain. This program has demonstrated that both cancer patients and their family caregivers benefit from a structured education program for relief of cancer pain.
