Development of a Subjective Workload Assessment for Nurses: A Human Factors Approach.

BACKGROUND AND PURPOSE: Research has revealed nurses' perception that traditional workload measures do not adequately capture the complexity of workload. Using a human factors approach to address the multiple and complex dimensions from the subjective perception of the worker, the Subjective Workload Assessment for Nurses (SWAN) was developed. METHODS: Survey data from 188 medical-surgical registered nurses were used to establish the instrument's psychometric properties. RESULTS: SWAN Sections 1, 2, and 3; General Information Form Section 1; and the Nursing Texas Load Index demonstrated internal consistency with this sample. Findings supported interrelationships between activity complexity, performance circumstances, and individual characteristics described in the literature. CONCLUSION: Further study is needed to refine the SWAN and to establish psychometric properties with nurses in other practice areas.

Expressive writing in early breast cancer survivors.

AIMS: This article is the report of a study aimed at determining whether or not expressive writing improves the quality-of-life of early breast cancer survivors. An additional aim is the investigation of whether or not the type of writing prompt makes a difference in results. BACKGROUND: The risk of distress can extend well beyond the time of a breast cancer diagnosis. Emotional expression may assist in dealing with this. DESIGN: Randomized controlled study. METHODS: Participants (n = 120) were randomized into one of four groups: a control group (no writing) or one of three expressive writing groups: breast cancer trauma, any self-selected trauma and facts related to breast cancer. Participants wrote 20 minutes a day for 4 consecutive days. Their quality-of-life was measured, using the 'Functional Assessment of Cancer Therapy-Breast Cancer Version', at baseline and at 1 month and 6 months after writing. Paired t-tests, multivariate analysis of variance and multiple regression were used to analyse the data of the 97 participants who completed the journaling assignment and at least the first assessment, collected in 2006. Intention-to-treat analysis was used. RESULTS/FINDINGS: Expressive writing about one's breast cancer, breast cancer trauma and facts related to breast cancer, significantly improved the quality-of-life outcome. CONCLUSION: Expressive writing, focusing the instructions on writing about one's living and dealing with a diagnosis of breast cancer, is recommended for early breast cancer survivors as a feasible and easily implemented treatment approach to improve quality-of-life.

A randomised trial of nursing interventions supporting recovery of the postmastectomy patient.

AIMS AND OBJECTIVES: This ABC to recovery study evaluated the combined and separate components of preoperative education and the effectiveness of wearing the Papilla Gown. BACKGROUND: Surgical removal of the breast may lead to activity limitation, self-image issues, discomfort and later complication of lymphoedema. Design. This study used experimental and longitudinal design. METHODS: One hundred and forty-five women undergoing mastectomies for stages two and three breast cancer were randomised into four groups: education and Papilla Gown, education only, gown only and control. The outcomes of activity (A), body image (B), comfort (C), knowledge and lymphoedema were assessed at baseline and/or 1 week and 6 months using three measures. All 145 participants completed the study questionnaires at first two measures, and forty-six of these participants completed the questionnaires at 6 months postoperatively. The setting for the study included two clinics and hospitals. To examine statistical significance at each time point after surgery, 2-way anovas were performed on ABC, knowledge and tape measurement to see whether there were any statistically significant differences between the four groups. All reported p-values are two sided. All statistical analyses were performed using sas 9.2 for Windows. RESULTS: The mean age of the sample was 55 years. The study revealed that women who received the combined intervention demonstrated greater activity. Women who wore the gown only had a greater comfort level and decreased lymphoedema. Women that received preoperative education experienced increased knowledge. CONCLUSIONS: Outcomes suggest that the combined intervention (ABCs to recovery) can improve recovery following mastectomy. Relevance to clinical practice. The results will be used to further modify the intervention and to increase awareness of nurse practitioners and other healthcare professionals of the specific needs of postmastectomy patients.

Factors that influence patient advocacy by pain management nurses: results of the American society for pain management nursing survey.

What is the meaning of advocacy, and how does it relate to the nurse who wants patients to experience optimum pain management? This question and the lack of empirical data provided the stimulus for the American Society for Pain Management Nursing (ASPMN) Research Committee to explore ASPMN members' beliefs, knowledge, and skills regarding pain management advocacy activities. The specific aim of the study was to determine the educational needs for and barriers of advocacy for nurses working with patients experiencing pain. An ASPMN Advocacy Survey Instrument was developed to gather data about advocacy activities and interventions. The sample consisted of 188 ASPMN nurses (20% of the membership) who responded via the internet. Study findings revealed that the majority of nurse respondents were active in personal advocacy, serving as guardians of the patient. They confronted physicians as necessary and assisted patients to evaluate their pain management. Regarding making the public aware of pain management-related issues (i.e., public awareness advocacy), the respondents were not as active. Respondents were knowledgeable about pain management and best practices/best evidence, with the exceptions of legislative issues and media training. These two areas need support and educational intervention. Additional areas in need of education and training, as identified by respondents, are social and political advocacy interventions. "Lack of time" was identified as the barrier to advocacy experienced by the greatest number of nurses.

A goal attainment pain management program for older adults with arthritis.

The purpose of this study was to test a pain management intervention that integrates goal setting with older adults (age > or =65) living independently in residential settings. This preliminary testing of the Goal Attainment Pain Management Program (GAPMAP) included a sample of 17 adults (mean age 79.29 years) with self-reported pain related to arthritis. Specific study aims were to: 1) explore the use of individual goal setting; 2) determine participants' levels of goal attainment; 3) determine whether changes occurred in the pain management methods used and found to be helpful by GAPMAP participants; and 4) determine whether changes occurred in selected pain-related variables (i.e., experience of living with persistent pain, the expected outcomes of pain management, pain management barriers, and global ratings of perceived pain intensity and success of pain management). Because of the small sample size, both parametric (t test) and nonparametric (Wilcoxon signed rank test) analyses were used to examine differences from pretest to posttest. Results showed that older individuals could successfully participate in setting and attaining individual goals. Thirteen of the 17 participants (76%) met their goals at the expected level or above. Two management methods (exercise and using a heated pool, tub, or shower) were used significantly more often after the intervention, and two methods (exercise and distraction) were identified as significantly more helpful. Two pain-related variables (experience of living with persistent pain and expected outcomes of pain management) revealed significant change, and all of those tested showed overall improvement.

Outcomes after unilateral lung volume reduction.

BACKGROUND: For patients with end-stage emphysema undergoing lung volume reduction surgery (LVRS), we have preferred a bilateral (BLVRS) approach to achieve maximum benefit with a single procedure. A unilateral (ULVRS) approach has been used in certain patients in whom BLVRS is contraindicated. METHODS: Between January 1993 and December 2006, 43 consecutive patients underwent ULVRS. The study excluded patients undergoing giant bullectomy. Relative contraindications for BLVRS were unilateral emphysema, 21; unilateral emphysema plus other factors, 2; and other factors alone, 10. Preoperative pulmonary rehabilitation was required. Postrehabilitation data were used as the baseline for analyses. Outcome measurements for ULVRS were compared with BLVRS results. RESULTS: After ULVRS, the mean increase in forced expiratory volume in 1 second (FEV(1)) from postrehabilitation values was 32% at 6 months (p

Expanding the comfort of postmastectomy patients using the Papilla Gown.

PURPOSE: To determine whether the Papilla Gown designed specifically to meet the needs of postmastectomy patients with a closed drainage system in place is more comfortable than is a typical hospital gown. BACKGROUND: The closed wound drainage system used for breast cancer patients immediately following mastectomy requires external drainage tubes that connect to a pouch. The pins that are usually used to attach the drains to a patient's gown create problems. The Papilla Gown (Papilla is the Latin term for breast) was designed with safety pouches for supporting the drains. METHODS: A convenience sample of 13 postmastectomy patients participated in this preliminary study of the gown's use. Participants were taught how to properly wear the typical hospital gown and Papilla Gown before surgery. Patients were discharged with the gowns and two questionnaires that were to be returned approximately 1 week following surgery. Thirteen of the 38 (34%) who agreed to participate submitted usable forms. The Wilcoxon signed-ranks test was used for comparing the comfort scores of the Papilla with the hospital gown. FINDINGS: Participants reported significantly higher scores (p<.003) for the Papilla Gown on all of Comfort Questionnaire's 10 items, except one (p=.337) related to fear of pulling out the drainage tubes. Specifically, patients felt more comfortable about their appearance in the gowns, their ability to move, and the support of the drainage tubes. CONCLUSION: The newly designed Papilla Gown shows promise for meeting the purpose of increasing the comfort of postmastectomy patients with closed drainage systems. CLINICAL RELEVANCE: The Papilla Gown was designed to address the comfort, mobility, and body image issues that patients face during the first week following a mastectomy, when they are dealing with such issues as the cancer diagnosis, loss of a breast, and managing drainage tubes. Preliminary results show that nurses can improve patient satisfaction by providing clothing that is comfortable, attractive, and supports the drainage system in place during this critical time.

A bone health intervention for older adults living in residential settings.

Osteoporosis, a major health problem that increases with age, may lead to fractures and loss of independence. This study focused on testing a bone health intervention aimed at assisting older adults living independently in residential settings to maintain healthy bones with the long-term goals of fracture prevention and maintenance of independent function. Forty-seven participants (M (age) = 79.36 years) completed six 1-hour educational sessions. Pre-intervention testing of osteoporosis knowledge and healthy bone behaviors was followed by posttests at 1 week, 6 weeks, and 7(1/2) months. Findings revealed significant increases in knowledge and behaviors from baseline to 9(1/2) months, although a slight decline during the last 6 months when there was no reinforcement of learning suggests the need for periodic follow-up.

Measurement of the experience of living with primary recurrent headache.

Recurrent primary headache is a major public health concern that impacts both society and the individual, reducing productivity and limiting participation in work, social, and leisure activities. The purpose of this study was to develop a valid and reliable instrument to measure the experience of living with chronic recurrent primary headache. This tool, Chronic Pain Experience Instrument-Headache Version (CPEI-HA), is intended to provide a measure of the affective component of headache that could complement the assessment of intensity, density, and disability. Psychometric testing of 25 items with a community-based headache sample ( N = 150) resulted in a 19-item tool with high internal consistency (alpha = .92). Principal components analysis was used to explore the meaning of the headache experience, and three underlying dimensions (i.e., Helplessness, Stress--Personal and Interpersonal, and Emotional Struggle) emerged to provide a better understanding of the experience. Construct validity was supported by the empiric relationships between the CPEI-HA and the eight theoretically related health concept subscales of the RAND 36-Item Health Survey 1.0. As predicted, all of the relationships were positive and in the moderate range (.31-.52). Findings suggest that the CPEI-HA has the potential for providing a valid and reliable tool for both clinical and research applications with persons who experience primary recurrent headaches.

Vaccination with live attenuated simian immunodeficiency virus for 21 days protects against superinfection.

The identification of mechanisms that prevent infection with human immunodeficiency virus (HIV) or simian immunodeficiency virus (SIV) would facilitate the development of an effective AIDS vaccine. In time-course experiments, protection against detectable superinfection with homologous wild-type SIV was achieved within 21 days of inoculation with live attenuated SIV, prior to the development of detectable anti-SIV humoral immunity. Partial protection against superinfection was achieved within 10 days of inoculation with live attenuated SIV, prior to the development of detectable anti-SIV humoral and cellular immunity. Furthermore, co-inoculation of live attenuated SIV with wild-type SIV resulted in a significant reduction in peak virus loads compared to controls that received wild-type SIV alone. These findings imply that innate immunity or non-immune mechanisms are a significant component of early protection against superinfection conferred by inoculation with live attenuated SIV.

Lung cancer resection combined with lung volume reduction in patients with severe emphysema.

OBJECTIVE: Certain patients with resectable lung cancer and severe respiratory limitation due to emphysema may have a suitable operative risk by combining cancer resection with lung volume reduction surgery. The purpose of this study is to review our experience with such patients. METHODS: A review was conducted on 21 patients with lung cancer in the setting of severe emphysema who underwent an operation designed to provide complete cancer resection and volume reduction effect. RESULTS: In the 21 patients, the mean preoperative forced expiratory volume in 1 second was 0.7 +/- 0.2 L (29% predicted), residual volume was 5.5 +/- 1.0 L (271%), and diffusing capacity for carbon monoxide was 8.0 +/- 2.2 mL/min/mm Hg (34% predicted). In 9 patients, the cancer was located in a severely emphysematous lobe and the lung volume reduction surgery component of the procedure was accomplished with lobectomy alone. In the remaining 12 patients, the cancer resection lobectomy (n = 9) and wedge resection (n = 3) were supplemented with lung volume reduction surgery. Final pathologic staging was stage I in 16 patients, stage II in 2 patients, and stage III in 2 patients. One patient was found to have stage IV disease due to multifocal tumors in separate lobes. There were no hospital deaths. Postoperative complications included prolonged air leak in 11 patients, atrial fibrillation in 6 patients, and reintubation for ventilatory assistance in 2 patients. All patients showed improved lung function postoperatively. Survival was 100% and 62.7% at 1 and 5 years, respectively. CONCLUSIONS: Patients with severe emphysema and resectable lung cancer who have a favorable anatomy for lung volume reduction surgery may undergo a combined cancer resection and lung volume reduction surgery with an acceptable risk and good long-term survival.

Results of lung volume reduction surgery in patients meeting a national emphysema treatment trial high-risk criterion.

OBJECTIVES: A report from the National Emphysema Treatment Trial indicated that lung volume reduction candidates with a forced expiratory volume in 1 second and a diffusing capacity of carbon monoxide of 20% or less of predicted value were at high risk for mortality and were unlikely to benefit from surgical intervention. This article examines the applicability of the National Emphysema Treatment Trial findings to our own patients. METHODS: We reviewed 280 patients who underwent bilateral lung volume reduction surgery at our institution between January 1993 and December 2001. All patients met our selection criteria, including heterogeneous distribution of emphysema. Of these 280 patients, 20 patients had both a preoperative forced expiratory volume in 1 second and a diffusing capacity of carbon monoxide of less than or equal to 20% of the predicted normal values, thus meeting one National Emphysema Treatment Trial criterion for high risk. Outcomes of the 20 patients were assessed through 5 years after the operation. The survival of the 20 patient cohort was compared with that of the 260 patients not meeting the National Emphysema Treatment Trial high-risk criterion. RESULTS: Ninety-day operative mortality included 1 (5%) patient. In all patients the forced expiratory volume in 1 second increased from 0.46 L (17%) to 0.78 L (32%), a 73% change; the diffusing capacity of carbon monoxide increased from 16% to 27%, a 70% improvement; residual volume decreased from 6.33 L (305%) to 4.26 L (205%), a 33% improvement; and room air arterial partial pressure of oxygen increased from 55 mm Hg to 64 mm Hg. Kaplan-Meier 5-year survivals did not differ between the high-risk and non-high-risk groups. CONCLUSIONS: Patients with a forced expiratory volume in 1 second and a diffusing capacity of carbon monoxide of 20% or less of predicted value might experience improvements in lung function, exercise tolerance, and quality of life with acceptable morbidity and mortality after lung volume reduction surgery.

Persistence and dissemination of simian retrovirus type 2 DNA in relation to viremia, seroresponse, and experimental transmissibility in Macaca fascicularis.

Endemic simian retrovirus (SRV) infection can cause fatal simian AIDS in Macaca fascicularis, but many individuals survive with few clinical signs. To further clarify the parameters of SRV pathogenesis, we investigated the persistence of viral DNA forms in relation to active viremia, antibody response, and transmissibility of infection. In M. fascicularis from endemically SRV-2-infected colonies, viral DNA was present in both linear and unintegrated long terminal repeat circular forms in peripheral blood mononuclear cells of all viremic and many nonviremic animals. Long-term followup of three individuals with distinct infection patterns demonstrated persistence of linear and circular forms of viral DNA in peripheral blood mononuclear cells and tissues, irrespective of viremia or antibody status, but reactivation of latent infections was not observed. The role of viral DNA in transmission and early pathogenesis of SRV-2 was investigated by inoculation of SRV-2 DNA-positive blood into groups of naïve M. fascicularis from either a viremic or nonviremic donor and subsequent analysis of the virological and serological status of the recipients. Transmission of SRV and development of anti-SRV antibodies were only observed in recipients of blood from the viremic donor; transfer of SRV provirus and unintegrated circular DNA in blood from the nonviremic donor did not lead to infection of the recipients. These results indicate that a proportion of M. fascicularis are able to effectively control the replication and infectivity of SRV despite long-term persistence of viral DNA forms in infected lymphocytes.

Improved sleep may reduce arthritis pain.

Studies indicate that pain interferes with sleep and, in turn, sleep disturbances increase pain. Statistics show that up to 60% of those with arthritis experience pain during the night. But despite these findings, sleep is not generally addressed as a major treatment concern among this population. This article reviews the relationship between pain and sleep; sleep issues as they relate to 3 common types of arthritis--osteoarthritis, rheumatoid arthritis, and fibromyalgia; and holistic approaches that may be used by the patient in the self-management of pain and sleep.

Functional status in older women following hip fracture.

BACKGROUND: Women aged 65 years and over are at high risk for a fractured hip because of osteoporosis. One of the devastating effects of a fracture is the loss of ability to live independently. AIM: The major aim of this study was to describe the functional status, or ability to perform activities of daily living, of women aged 65 years and older who had experienced a fractured hip in the recent past and to explore possible differences in selected variables (e.g. age and length of rehabilitation) for those who were fully performing activities of daily living at least 6 months after fracture and those who were not. DESIGN: Following Institutional Review Board approval, data were collected from 23 Caucasian women ranging from 65 to 95 years of age (M = 82, SD = 6.83) who had experienced fractured hips related to a fall in the recent past (6 months to 4 years). All were living independently prior to their fractures. Three Registered Nurses, in a structured interview, collected the data using a Demographic Data Form, an Osteoporosis Risk Factor Checklist, the Katz Index of Independence in Activities of Daily Living, and the Lawton Instrumental Activities of Daily Living Scales. RESULTS: Nine of the participants reported prior fractures, suggesting that this could have been a risk factor for this group. Eighteen achieved the maximum independence score of six on the Katz Index of Independence in Activities of Daily Living; help with bathing was required by the other five. Of the Instrumental Activities of Daily Living, those requiring physical activity for home maintenance were the most problematic. Ability to perform Instrumental Activities of Daily Living was significantly related to ability to perform the activities required to live independently. CONCLUSIONS: Results suggest that achieving a functional level that will support independence is possible for older women who were residing independently prior to a hip fracture.

A prospective evaluation of lung volume reduction surgery in 200 consecutive patients.

OBJECTIVES: Though numerous studies have demonstrated the short-term efficacy of lung volume reduction surgery (LVRS) in select patients with emphysema, the longer-term follow-up studies are just being reported. The primary objectives of this study were to assess long-term health-related quality of life, satisfaction, physiologic status, and survival of patients following LVRS. DESIGN: We used a prospective cohort study design to assess the first 200 patients undergoing bilateral LVRS (from 1993 to 1998), with follow-up through the year 2000. Each patient served as his own control, initially receiving optimal medical management including exercise rehabilitation before undergoing surgery. Preoperative postrehabilitation data were used as the baseline for comparisons with postoperative data. The primary end points were the effects of LVRS on dyspnea (modified Medical Research Council dyspnea sale), general health-related quality of life (Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]), patient satisfaction, and survival. The secondary end points were the effects of LVRS on pulmonary function, exercise capacity, and supplemental oxygen requirements. SETTING: A tertiary care urban university-based referral center. PATIENTS: Eligibility requirements for LVRS included disabling dyspnea due to marked airflow obstruction, thoracic hyperinflation, and heterogeneously distributed emphysema that provided target areas for resection. Patients were assessed at 6 months, 3 years, and 5 years after surgery. INTERVENTIONS: Preoperative pulmonary rehabilitation and bilateral stapling LVRS. MEASUREMENTS AND RESULTS: The 200 patients accrued 735 person-years (mean +/- SD, 3.7 +/- 1.6 years; median, 4.0 years) of follow-up. Over the three follow-up periods, an average of > 90% of evaluable patients completed testing. Six months, 3 years, and 5 years after surgery, dyspnea scores were improved in 81%, 52%, and 40% of patients, respectively. Dyspnea scores were the same or improved in 96% (6 months), 82% (3 years), and 74% (5 years) of patients. Improvements in SF-36 physical functioning were demonstrated in 93% (6 months), 78% (3 years), and 69% (5 years) of patients. Good-to-excellent satisfaction with the outcomes was reported by 96% (6 months), 89% (3 years), and 77% (5 years) of patients. The FEV(1) was improved in 92% (6 months), 72% (3 years), and 58% (5 years) of patients. Changes in dyspnea and general health-related quality-of-life scores, and patient satisfaction scores were all significantly correlated with changes in FEV(1). Following surgery, the median length of hospital stay in survivors was 9 days. The 90-day postoperative mortality was 4.5%. Annual Kaplan-Meier survival through 5 years after surgery was 93%, 88%, 83%, 74%, and 63%, respectively. During follow-up, 15 patients underwent subsequent lung transplantation. CONCLUSIONS: In stringently selected patients, LVRS resulted in substantial beneficial effects over and above those achieved with optimized medical therapy. The duration of improvement was at least 5 years in the majority of survivors.

Long-term outcome of bilateral lung volume reduction in 250 consecutive patients with emphysema.

OBJECTIVE: Numerous reports have confirmed the early benefits of lung volume reduction surgery for selected patients with emphysema. This report documents the long-term survival and functional results after lung volume reduction surgery. METHODS: Between January 1993 and June 2000, a total of 250 consecutive patients underwent bilateral lung volume reduction surgery through median sternotomy at our institution. All patients had disabling dyspnea, thoracic hyperinflation, and a heterogeneous pattern of emphysema with suitable target areas for resection. Preoperative pulmonary rehabilitation was required and post-rehabilitation data were used as the baseline for data analysis. Follow-up ranged from 1.8 to 9.1 years (median 4.4 years). RESULTS: Prolonged air leaks (>7 days) were the most common complication (45.2%, n = 113). Reexploration rates for air leak and bleeding were 3.2% (n = 8) and 1.2% (n = 3), respectively. Eighteen patients (7.2%) required reintubation and mechanical ventilation. The in-hospital mortality in this series was 4.8% (n = 12). The median length of hospitalization was 9 days (range 4-168 days). Kaplan-Meier survivals after lung volume reduction surgery were 93.6%, 84.4%, and 67.7% at 1, 3, and 5 years, respectively. Eighteen patients (7.2%) have subsequently undergone lung transplantation after a median interval of 4.3 years (range 2.1-6.4 years). Spirometric values, lung volumes, and gas exchange parameters improved after surgery. The forced expiratory volume in 1 second and the residual volume showed statistically significant improvements between preoperative values and each time point of follow-up. Health-related quality of life showed significant postoperative improvement and with time correlated well with the improvement in forced expiratory volume in 1 second. CONCLUSIONS: Lung volume reduction surgery produces significant functional improvement for selected patients with emphysema. For most of these patients, benefits appear to last at least 5 years.

Population-based osteoporosis education for older women.

With an increased focus on wellness and health promotion, there is a need for community-based strategies to complement traditional strategies aimed at improving individual and aggregate health. An educational program on the prevention, diagnosis, and treatment of osteoporosis was provided for 188 women age 60 and older in three different community settings: churches, retirement homes, and senior citizen centers. The major purposes of the study were to determine whether a community-based program might (a) contribute to older women's knowledge about osteoporosis and (b) promote their intent to use this knowledge. Each participant completed a demographic profile, the Osteoporosis Risk Checklist, and the Osteoporosis Knowledge Questionnaire (OKQ), with the OKQ serving as a pre- and post-test. Before post-testing, a 30-min educational program was provided. Differences among the three groups were risk factors, prior knowledge about osteoporosis, and knowledge at the completion of the program. A majority of the clients indicated an intent to increase calcium in their diet, discuss osteoporosis with their health care provider, check their home environment for safety/falls, and discuss what they had learned with others. Nurses need to plan educational programs in all settings to teach older clients about the risk factors, prevention, diagnosis, and treatment of osteoporosis.

The measurement of patient satisfaction.

Patient satisfaction is an important quality outcome indicator of health care in the hospital setting. The measurement of patients' satisfaction with nursing is particularly important since nursing service is often a primary determinant of overall satisfaction during a hospital stay. This article reports on a study designed to update and revise the definition of patient satisfaction for application with ambulatory surgical patients and to develop a questionnaire that captures this definition. The Patient Satisfaction Scale, which specifically focuses on patient satisfaction with nursing care and is used extensively by nursing researchers, was selected for factor analytical examination. Psychometric testing resulted in a 15-item scale with three underlying dimensions.
