Facilitating positive outcomes in older adults with wounds.

Older people with wounds are not the same as younger people with wounds. Older people experience biologic differences in wound healing that result in delayed healing, increased wound infection, and a greater incidence of dehiscence. Clinicians need to assess the risk of dehiscence in the older population, looking for serous drainage from the incision line and the absence of a palpable healing ridge. It is critical to recognize that older persons' presentation of wound infection is atypical. More subtle signs such as alteration in cognitive status and changes in function may indicate the presence of infection. The clinician who cares for older persons must be an exquisite detective when such changes occur to identify the source of the problem. As part of the normal trajectory of aging, older persons experience sensory loss and so may require accommodation when explanations are given to them about their wound and their wound care choices. Health care providers must consider hearing and vision changes that occur in older adults and tailor their explanations and teaching so that the message reaches the older adult and is successfully processed. Older persons have a higher incidence of cognitive changes and functional decline than do their younger counterparts, and these changes need to be assessed before a plan of care is developed to care for the older person with a wound. Limited data are available to help the clinician know the cognitive and functional level that is critical for older persons to understand their wound care choices, perform their own wound care, and to make choices about who will provide the care if they are unable to perform self-care. These seemingly basic issues raise questions for clinicians as we strive to provide evidence-based care to this ever-increasing population of older Americans.

Cultural factors and medication compliance in Chinese immigrants who are taking antihypertensive medications: instrument development.

Chinese immigrants in the United States have a moderate to high prevalence of hypertension, but little is known about antihypertensive medication compliance in Chinese immigrants. This study presents some first-generation measures of antihypertensive medication compliance in a sample of Chinese immigrants. A literature review and two qualitative pilot studies were conducted to generate culturally sensitive instruments. Items were developed to assess cultural factors and medication compliance in Chinese immigrants receiving antihypertensive medications. Cultural factors included measures of cultural health perception of hypertension, health perceptions of Chinese herbs, health perceptions of Western medications, beneficial self-care behaviors, and social support. Four medication compliance scales were developed. The applicability of these scales was tested in a Chinese immigrant population (n=200). Cronbach's alpha for the cultural factors scales ranged from .57 to .91. Two of the medication compliance scales had Cronbach's alphas above .60. Results showed that most of the scales are applicable and acceptable in a Chinese immigrant population and had good reliability. However, further testing with a larger sample in other regions of the country is indicated.

Attitudes of critically ill Filipino patients and their families toward advance directives.

BACKGROUND: Advance directives are important but often underused tools in critical care. Healthcare professionals' understanding of how culture influences attitudes toward advance directives can improve knowledge and completion of these documents. OBJECTIVE: To understand the attitudes of critically ill Filipino American patients and their families toward advance directives. METHODS: A descriptive, correlational, cross-sectional study with a convenience sample of 22 Filipino American patients and 22 Filipino American family members at a West Coast medical center. All patients were admitted for cardiac surgery or cardiac interventions. Participants were interviewed with the Advance Directive Attitude Survey and A Short Acculturation Scale for Filipino Americans. RESULTS: Family members' scores were significantly more positive than patients' scores on the attitude survey (P = .01). Family members were more American acculturated than were patients (P = .001). Family members with more education had more positive attitudes toward advance directives (P = .02). Only 2 patients (and no family members) had completed an advance directive before the study. Only 27.3% of family members had prior knowledge of advance directives. CONCLUSION: Overall attitudes toward advance directives were positive; however, the completion rate and knowledge of advance directives were low. Participants may have been saying what they thought the researcher wanted to hear in order to avoid disagreement. Such behavior could partly explain the positive attitudes of the Filipino Americans toward advance directives. Further research is warranted to understand how to increase completion rates for advance directives among Filipino Americans.

The link between tissue oxygen and hydration in nursing home residents with pressure ulcers: preliminary data.

Pressure ulcers are prevalent in nursing home residents. They heal slowly and result in pain and impaired quality of life. Strategies to enhance healing of pressure ulcers are critical to the treatment regime in nursing homes. This article explores the possibility that nursing home residents with pressure ulcers may experience low tissue oxygen and impaired hydration. Pilot data are presented suggesting that some proportion of nursing home residents with pressure ulcers experience low subcutaneous oxygen and that fluid administration increases the low tissue oxygen. Further research in this area is warranted.

Physiology and prevention of heel ulcers: The state of science.

The prevalence of heel ulcers across settings is high and is increasing. Prevention of ulcers requires knowledge of their etiology and the scientific basis for preventive care. The interaction between external pressure and the heel vasculature is central to the prevention of heel ulcers. This article focuses on the prevention of heel pressure ulcers. The physiology of heel tissue perfusion, the effect of external pressure on heel perfusion, as well as what is known about strategies to reduce external pressure and approaches to improve heel skin blood flow will be discussed. It is only through understanding of the physiology of heel tissue perfusion and its relation to external pressure that effective preventive measures to reduce heel skin breakdown can be adapted in clinical practice.

Mechanisms for radiation-induced oral mucositis and the consequences.

Radiation therapy remains the primary method of treatment for patients with head and neck cancer. The tissue destruction and functional alterations in the oral cavity lead to the development of oral mucositis. The purpose of this review is to describe the mechanisms, risk factors, prevalence, and magnitude of radiation therapy-related oral mucositis and its morbidities in patients with head and neck cancer. The review concludes with a discussion of the implications for clinical practice. This review provides cancer nurses with the information necessary to identify patients with head and neck cancer who are at high risk for oral mucositis and the significant comorbidities associated with this complication of radiation therapy.

Factors to consider when analyzing 12-lead electrocardiograms for evidence of acute myocardial ischemia.

An important factor to consider when using findings on electrocardiograms for clinical decision making is that the waveforms are influenced by normal physiological and technical factors as well as by pathophysiological factors. Traditionally, the focus of bedside monitoring is detection of arrhythmia. However, continuous ST-segment monitoring for the detection of myocardial ischemia is now readily available. Many factors affect electrocardiographic waveforms and may interfere with diagnosis of myocardial ischemia based on electrocardiographic findings. Accordingly, a principal leadership role for clinical nurse specialists and nurse practitioners is to become knowledgeable about interpretation of 12-lead electrocardiograms and to share this knowledge with staff nurses who care for patients with acute coronary syndromes. The factors that alter electrocardiographic findings are reviewed, and the alterations that interfere with electrocardiogram-based diagnosis of myocardial ischemia are discussed.

A research review of the current treatments for radiation-induced oral mucositis in patients with head and neck cancer.

PURPOSE/OBJECTIVES: To review the research studies on the current treatments for radiation therapy-(RT-) induced mucositis in patients with head and neck cancer. DATA SOURCES: MEDLINE search of the literature from 1966-2001. DATA SYNTHESIS: Four types of agents (i.e., antimicrobial, coating, anti-inflammatory, and cytokine-like agents) have been evaluated for the management of RT-induced oral mucositis in patients with head and neck cancer. Most of the published studies had relatively small sample sizes and used inconsistent measures to evaluate the extent and severity of oral mucositis. Therefore, definitive conclusions regarding the effectiveness of any of the agents tested in the prevention and treatment of RT-induced oral mucositis cannot be drawn. CONCLUSIONS: Oral mucositis remains the most common complication among patients with head and neck cancer. Although a number of strategies and products are being investigated and new directions are promising, the therapies tested to date have not produced consistent results. IMPLICATIONS FOR NURSING: The most effective measure to treat RT-induced mucositis in patients with head and neck cancer is frequent oral rinsing with a bland mouthwash, such as saline or a sodium bicarbonate rinse, to reduce the amount of oral microbial flora. Dental care, consistent oral assessments, and the initiation of a standardized oral hygiene protocol before the initiation of cancer treatment are the most effective approaches for oral mucositis.

Wound care pain in hospitalized adult patients.

BACKGROUND: Wound care (WC) is an important part of treatment for hospitalized patients with wounds. There is a paucity of data about the type or amount of pain patients experience during WC. OBJECTIVES: The purpose of this study is to describe patients' (n = 412) WC-related pain perceptions and responses, examine the relationships between patients' WC pain and demographic variables, and describe the distress associated with WC. METHODS: A repeated-measures design was used to examine pain before, during, and after WC in hospitalized patients (n = 412) with wounds healing by secondary intention. RESULTS: Pain intensity was greatest during WC. It was most frequently described as tender, sharp, stinging, aching, and stabbing. Behaviors that occurred most often were no verbal response, no body movement, grimace, and complaints of pain. There were no differences in pain between genders. Nonwhites had significantly greater WC pain than whites. Pain during the procedure was the same in younger and older patients, and procedural distress was mild. CONCLUSION: Patients experience pain and distress with WC. Some behaviors and words consistently describe WC pain. Further work is warranted to refine pain assessment and management in patients undergoing WC procedures.

Improvement in balance, strength, and flexibility after 12 weeks of Tai chi exercise in ethnic Chinese adults with cardiovascular disease risk factors.

CONTEXT: Declines in physical performance are associated with aging and chronic health conditions. Appropriate physical activity interventions can reverse functional limitations and help maintain independent living. Tai chi is a popular form of exercise in China among older adults. OBJECTIVE: To determine whether tai chi improves balance, muscular strength and endurance, and flexibility over time. DESIGN: Repeated measures intervention; data collected at baseline, 6 weeks, and 12 weeks. SETTING: Community center in the San Francisco Bay Area. PARTICIPANTS: Thirty-nine Chinese adults with at least 1 cardiovascular disease (CVD) risk factor. INTERVENTIONS: A 60-minute tai chi exercise class 3 times per week for 12 weeks. MAIN OUTCOME MEASURES: A battery of physical fitness measures specifically developed for older adults assessed balance, muscular strength and endurance, and flexibility. RESULTS: Subjects were 65.7 (+/- 8.3) years old, Cantonese-speaking (97%) immigrants, with 12 years or less of formal education (87%) and very low income (67%). Reported CVD risk factors were hypertension (92%), hypercholesteremia (49%), diabetes (21%), and 1 current smoker. Subjects were below the 50th percentile of fitness at baseline compared to age- and gender-specific normative US data. Statistically significant improvements were observed in all balance, muscular strength and endurance, and flexibility measures after 6 weeks, and they increased further after 12 weeks. CONCLUSIONS: Tai chi is a potent intervention that improved balance, upper- and lower-body muscular strength and endurance, and upper- and lower-body flexibility in these older Chinese adults. These findings provide important information for future community-based tai chi exercise programs and support current public health initiatives to reduce disability from chronic health conditions and enhance physical function in older adults.
