Informational needs of women with a recent diagnosis of breast cancer: development and initial testing of a tool.

This study developed and tested the Toronto Informational Needs Questionnaire-Breast Cancer (TINQ-BC), a questionnaire designed to identify the information which women with a recent diagnosis of breast cancer need to deal with their illness. The 73-item questionnaire had content validity based on findings in the literature and opinions of expert oncology nurses. It was administered to 114 women with a recent diagnosis of breast cancer during chemotherapy (n = 39), radiation therapy (n = 40) or surgery (n = 35). Item analysis determined that 51 items in five subscales should be retained in the questionnaire. The subscales, labelled Disease, Investigative Tests, Treatments, Physical, and Psychosocial had good internal consistency reliabilities with Cronbach's alphas of 0.81 to 0.93. Informational needs of women were high with mean scores over 200 in a possible range of 51-255. Informational needs were greatest in either the Disease or Treatments subscales. Marital status, level of education, and level of income were not related to level of informational need. Younger women had a greater need for information than older women (r = -0.35, P = 0.003). The results suggest that information is important to help women with breast cancer manage their illness. Nurses should give women an opportunity to ask questions and be prepared to give accurate information.

Information needs of women during early treatment for breast cancer.

This study assessed the information needs of 70 women with breast cancer being treated by surgery, chemotherapy or radiation therapy. Information needs were measured by the breast cancer version of the Toronto Informational Needs Questionnaire (TINQ-BC). All women had high information needs, irrespective of type of treatment received. They mainly wanted information about their disease, treatments and investigative tests. An examination of individual items on the TINQ-BC revealed that all women wanted information about recurrence, specifically they wanted to know if the cancer would come back and how to tell if it had recurred. The results provide nurses with some direction as to what information to give women receiving early treatment for breast cancer.

Catecholamines contribute to exertional dyspnoea and to the ventilatory response to exercise in normal humans.

BACKGROUND: Exogenous catecholamine administration in humans stimulates ventilation. The present study was designed to investigate whether increased endogenous catecholamine release influences objective measures of ventilation and subjective measures of breathlessness in normal subjects. METHODS: Yohimbine, a pre-synaptic alpha 2 adrenoceptor antagonist, or placebo was administered to 10 normal male subjects in a double-blind cross-over fashion. Ventilation and metabolic gas exchange were measured during steady state exercise at 60% of previously determined maximal oxygen consumption. Venous lactate and noradrenaline were measured during exercise. Subjects' sensation of breathlessness and fatigue were recorded using visual analogue scales. RESULTS: Plasma noradrenaline was higher following yohimbine administration (at 6 min exercise; 4.58 +/- 0.56 nmol.l-1 vs 8.74 +/- 1.53; P < 0.05). Oxygen consumption was unchanged, but ventilation was greater throughout exercise following yohimbine. The sensation of exertion was greater following yohimbine, and at any given level of ventilation, the sensation of exertion was greater. CONCLUSIONS: Yohimbine administration causes increased noradrenaline release. This is associated with an increased ventilatory response and an increase in the sensation of exertion during steady state exercise. An increase in circulating noradrenaline might be a mechanism for both increased ventilation and pathological conditions of breathlessness such as chronic heart failure.

Discharge information needs and symptom distress after abdominal aortic surgery.

The purpose of this study was to describe the discharge information needs and symptom distress of people after abdominal aortic reconstructive surgery. Interviews (N = 51) were conducted prior to, and 4 weeks after, hospital discharge. People indicated that the most important information to help them manage their care after discharge related to the recognition, prevention and management of complications. Broken sleep and incisional pain were the most distressful of symptoms prior to hospital discharge, whereas fatigue and broken sleep were most distressful once home. These results may assist nurses to understand the discharge information needs and symptom distress of people recovering from aortic reconstructive surgery and the importance of discharge education to help people to manage their care once home.

Symptom distress, anxiety, depression, and discharge information needs after peripheral arterial bypass.

The purpose of this study was to describe the symptom distress, anxiety, depression, and discharge information needs of patients after peripheral arterial bypass surgery. Patients (n = 38) were interviewed before and after hospital discharge. The symptoms of incisional pain and broken sleep, as measured by Visual Analogue Scales, were the most distressing symptoms experienced before and after discharge. Patients reported low levels of anxiety and depression as measured by the Profile of Mood States. A moderate amount of information, assessed by the Patient Learning Need Scale, was perceived by patients to be important to help manage their care after discharge. The most important information related to the recognition, prevention, and management of complications. The findings contribute to an understanding of discharge information needs after peripheral arterial bypass and emphasizes the importance of patient education to facilitate transition to the home.

Recruiting and retaining registered nurses in home healthcare.

This study examined a personal and professional profile of registered nurses in home care to determine the most influential factors affecting their recruitment, job satisfaction, and retention. With the cooperation of a national, for-profit home healthcare organization in 1990, the authors randomly surveyed its registered nurses, licensed practical nurses, and home health aides in two Midwestern states. Findings for 107 home care registered nurses are presented and compared with responses of licensed practical nurses and home health aides.

Bridging the gap between research and clinical practice: a collaborative approach.

In nursing, a gap sometimes exists between research and practice. This paper discusses how a group of 11 nurses successfully bridged this gap. The group was composed of nurses from a large teaching hospital, a regional outpatient cancer center, and a university. The result of the group's work over a two-year period was an externally funded research proposal. This paper discusses the strategies that led to the group's success and provides specific recommendations for nurses who want to form similar groups.

The dosimetry of iodine-123-labeled TISCH: a SPECT imaging agent for the D1 dopamine receptor.

TISCH is an iodinated D1 specific dopamine receptor antagonist that may be useful as a SPECT imaging agent. This report documents its pharmacological safety in animals and its radiation dosimetry in humans. The dose of radiation that 123I-TISCH delivered to seven healthy subjects was estimated with the absorbed fraction technique. Conjugate images of the body were serially acquired for up to 24 hr after the administration of a known amount of activity. The count rates in the organs that could be visualized were measured on each image. These count rates were corrected for attenuation with 123I transmission scans. The doses to the other organs that did not take up enough activity to be visualized on the images were estimated with established models. The dosimetry was calculated for each subject individually before the results were averaged. Rapid biological washout minimizes the radiation exposure to most organs. The dose to the large bowel is limiting in healthy volunteers. The proximal colon receives about 0.67 rad/mCi (180 microGy/MBq) or about 5 rads for every 7.5 mCi of TISCH injected. This low radiation burden should make it feasible to study the D1 dopamine receptor in patients who have neuropsychiatric disorders before and after treatment.

Caught in the middle. A profile of licensed practical nurses in home care.

Licensed practical nurses are the smallest major segment of the home care industry, providing services with registered nurses and home care aides. Although they report high job satisfaction, LPNs are caught at a middle stage in the health care system. With new demographics, labor market considerations, and recruitment experiences, this report points out the discrepancy between the stalled LPN status and their industry growth.

Factors influencing patients' informational needs at time of hospital discharge.

The relationship between patients' perceived informational needs and selected sociodemographic and illness-related variables were examined in a sample of 301 adult medical and surgical patients preparing for discharge from an acute care setting. Marital status, living arrangements and chronicity of illness had no influence on the importance of informational needs as measured by the Patient Learning Need Scale (PLNS). More informational needs were identified by females than males, and those with malignant as opposed to benign disease. Length of time spent in the hospital, number of discharge medications, and patient perception of the influence of the illness on life were positively correlated with informational needs at the time of discharge.

The Patient Learning Needs Scale: reliability and validity.

The article describes the development and initial psychometric evaluation of an instrument to measure patients' perceptions of learning needs at time of discharge from hospital to home. Evaluation of the Patient Learning Needs Scale was based on responses of 301 adults hospitalized with a medical or surgical illness. Factor analysis isolated seven subscales: medications, activities of living, feelings related to condition, community and follow-up, treatment and complications, enhancing quality of life and skin care. These seven factors accounted for 56.1% of the variance. Cronbach's alpha for the 50-item scale was 0.95.

Dream recall: imagination, illusion and tough-mindedness.

The failure of dream psychology to delineate clear, consistent and interesting correlates of dream recall presents serious difficulties for the claim that dream recall is functionally significant. The present study examined the relation of six indices of boundary functioning and four measures of life affect to the consistency and frequency of dream recall in 373 young adults. Factor analysis indicated that consistency and frequency of dream recall were unrelated to global measures of boundary functioning, stress, depression, hassles and uplifts. On the assumption that the correlates of dream recall might be specific rather than global, 34 items from our expanded boundary questionnaire having significant zero order correlations with the frequency of dream recall were factor analyzed separately for consistent and inconsistent recallers. The two factors in each analysis were quite similar. Factor one was called the Imagination, factor two, Illusion. Among consistent recallers, dream recall and a group of items called "tough mindedness" loaded on the Imagination factor. For inconsistent recallers similar variables loaded on the Illusion factor. For all subjects, dream recall and tough mindedness were linked whether associated with Imagination or Illusion. The Imagination factor is creative and linked to dream recall for consistent recallers. Their illusion factor is frightening. For inconsistent recallers, the Illusion factor is linked to dreaming and is not frightening, and their Imagination factor is not creative. The stability-instability of dream generation and recall over time apparently results in the association of the dream recall tough-mindedness group of items with either the Imagination or Illusion factors.
