The influence of easy-to-read pamphlets about self-care management of radiation side effects on patients' knowledge.

PURPOSE/OBJECTIVES: To test patients' knowledge of side effects after they review six easy-to-read pamphlets on radiation side effects. DESIGN: Nonexperimental. SETTING: Urban radiation oncology clinic. SAMPLE: 47 patients receiving radiation treatment. METHODS: The Knowledge of Radiation Side Effects Test was administered. MAIN RESEARCH VARIABLES: Patient literacy and knowledge level. FINDINGS: The self-report of highest grade completed in school was 10th grade; however, the actual reading level was 4th-6th grade. Scores for each knowledge test increased with literacy level, with statistically significant correlations for pamphlets on fatigue, skin problems for women, and skin problems for men. Participants who read at the 4th-6th-grade level scored higher than expected. CONCLUSIONS: Although the pamphlets were deemed easy to read, patients who had the lowest reading levels still had difficulty understanding them. IMPLICATIONS FOR NURSING: In addition to written patient information, oncology nurses should use innovative teaching strategies to improve patient understanding and self-care behaviors. A need exists for continued nursing inquiry that will focus on self-care behaviors to manage radiation side effects, particularly for patients with low literacy.

The effect of low literacy on the self-care behaviors of men receiving radiation therapy.

Using Orem's theory as the framework, two purposes guided the study: (a) to test the effectiveness of an audio-visual education program and behavioral contracting to promote self-care behaviors in managing radiation side effects and (b) to determine the extent to which low literacy affects self-care abilities. Seventy men diagnosed with prostate cancer participated in this experimental study. The nursing interventions of education and behavioral contracting significantly increased the self-care behaviors of men in managing radiation side effects. An increase in self-care behaviors was especially shown in men with low-literacy skills.

Discharge knowledge and concerns of patients going home with a wound.

PURPOSE: To examine patients' wound care knowledge and concerns prior to discharge from an acute care hospital. DESIGN: Comparative descriptive study of patients with wounds. SETTING AND SUBJECTS: Participants (N = 76) included 17 men and 59 women who were African American (n = 33, 43.4%) or Caucasian (n = 43, 56.6%) and ranged in age from 20 to 83 years (M = 48, SD = 13). There were 67 persons with acute wounds and 9 with chronic wounds. All were scheduled to be discharged home from a large urban acute care hospital. INSTRUMENTS: The questionnaire for this study included the following sections: Demographic, Admission and Discharge, Health, Wound Care, Beliefs about Wounds and their Care, Pain and Wounds, Literacy and Learning, and Discharge Concerns. RESULTS: Participants' greatest concerns about going home were: (1) how active to be at home, (2) wound pain, (3) looking for wound complications, and (4) watching for wound infection. Many participants did not know the dressing (38.2%) or solution to cleanse the wound (58.7%) at home. Most had taken care of a wound before (67.1%), could see (68.4%) and reach (69.7%) the wound, and had looked at it (64.5%) during the hospitalization. Patients with acute and chronic wounds did not differ significantly in their concerns about their wound or their fear of taking care of their wound. Participants generally had appropriate knowledge about wounds and hand washing, nutrition, going out of the home, and cigarette smoking. They had incorrect information about drying out wounds and leaving them open to breathe the air. The majority of patients with chronic wounds preferred getting answers to questions about their wound and its care from their physician followed by their clinic and family/friends. Patients with acute wounds overwhelmingly chose their physician as a source of information about their wound and its care, followed by calling a nurse at the hospital and using the Internet. CONCLUSIONS: Patients were able to verbalize their concerns about going home with a wound. Concerns about discharge may help to direct patient teaching in preparation for discharge. Teaching literature could include the most common concerns, as well as ways to avoid misinformation about wound care. Discharge teaching needs to begin early so that patients feel they have adequate time to learn and ask questions. Further research is needed about patients' wound care knowledge and discharge concerns.

The impact of coronary artery disease risk factors on intravascular ultrasound-derived morphologic indices of human coronaries.

OBJECTIVE: The relationship of intravascular ultrasound (IVUS)-derived measurements of atherosclerotic plaque to various coronary artery disease (CAD) risk factors is not well known. The purpose of this study was to examine the relationship of percent coronary luminal stenosis by IVUS to other IVUS measures of CAD, as well as the relationship of common IVUS measures of CAD to traditional CAD risk factors. We hypothesized that one or more IVUS measures of CAD might relate more strongly to CAD risk factors than does percent luminal coronary stenosis. METHODS: The records of 897 consecutive patients (57% men, mean age 62 years) who underwent IVUS investigation of their coronary arteries from 1996 through 2001 were retrospectively reviewed. IVUS was performed using a 20-MHz probe (Jomed, Rancho Cordoba, CA) and a manual pull-back technique to image the coronary arteries. Coronary artery remodeling ratio-i.e., the ratio of coronary lesion external elastic membrane cross-sectional area (EEM CSA) to proximal reference artery EEM CSA; plaque burden-i.e., plaque plus media CSA divided by EEM CSA; calcium arc; and percent stenosis of luminal cross-sectional area were measured by a single reader. RESULTS: Percent area stenosis, the most commonly used IVUS parameter, did not correlate with the other three IVUS-derived parameters, nor was it related to any of the CAD risk factors considered. In contrast, remodeling ratio was directly correlated with plaque burden (r=0.22, P<0.001), but inversely related to calcium arc (r=-0.13, P=0.01). IVUS plaque burden was significantly correlated with male gender (P<0.0001) and diabetes mellitus (DM) (P=0.003). In multivariate analyses including age, gender, and CAD risk factors, plaque burden was significantly associated with age, male gender, and DM, but not with chronic renal failure, hypertension, or hypercholesterolemia. The multivariate model also revealed that the calcium arc was significantly associated with male gender and age. These IVUS findings provide anatomic documentation that the traditional CAD risk factors relate more strongly to plaque burden than to percent coronary arterial luminal narrowing.

Psychosocial stress and cardiovascular disease: pathophysiological links.

The remarkable decline in cardiovascular disease (CVD) experienced in developed countries over the last 40 years appears to have abated. Currently, many CVD patients continue to show cardiac events despite optimal treatment of traditional risk factors. This evidence suggests that additional interventions, particularly those aimed at nontraditional factors, might be useful for continuing the decline. Psychosocial stress is a newly recognized (nontraditional) risk factor that appears to contribute to all recognized mechanisms underlying cardiac events, specifically, (a) clustering of traditional cardiovascular risk factors, (b) endothelial dysfunction, (c) myocardial ischemia, (d) plaque rupture, (e) thrombosis, and (f) malignant arrhythmias. A better understanding of the behavioral and physiologic associations between psychosocial stress and CVD will assist researchers in identifying effective approaches for reducing or reversing the damaging effects of stress and may lead to further reductions of CVD morbidity and mortality.
