Measurement of stress in clinical nursing

The Nurse Stress Checklist was developed to measure stress in clinical nursing as a multidimensional construct. The instrument was formulated within a transactional model of stress. The items were derived from five domains thought to contribute to nurse stress in clinical settings and were organized into a questionnaire. Holmes Schedule of Recent Events was included as a validity measure. The instrument was tested on 104 staff nurses working in three institutions in an urban community. Exploratory factor analysis was applied to the 74 items presented to subjects in Likert-type format. Five factors were derived and subjected to psychometric evaluation. Internal consistency reliability for the five factors was good, ranging from 0.80 to 0.91. Means and measures of dispersion supported the potential of the five subscales to discriminate among respondents on the attributes being measured. Intercorrelations of the factors provided evidence of the distinctiveness of the five components of stress, although factor loadings showed some overlap between Personal Reactions and Work Concerns and Work Concerns and Work Completion Concerns. Validity of the factors also was supported by correlations with Holmes' Schedule of Recent Events. Content validity was supported by comparison of these results with findings of other investigators. Limitations of the results are discussed, and recommendations for future work on the instrument are offered.

Pain attitudes and knowledge among RNs, pharmacists, and physicians on an inpatient oncology service

Patients with cancer often experience pain, yet studies continue to document inadequate and inappropriate assessment and management of cancer-related pain. This study aimed to evaluate the attitudes and knowledge of inpatient oncology healthcare providers toward pain management by surveying nurses, pharmacists, and physicians working on the inpatient oncology units at an academic medical center. Healthcare providers generally reported positive attitudes toward pain management but were deficient in their knowledge of pain management. The authors suggest that pharmacists become more integral members of palliative care teams and actively participate in rounds. A need exists for educational programs in pain management for healthcare providers, especially for those who do not routinely care for patients with cancer.     

Gaps and contract: evaluating the diffusion of new information. Part II. The measurement of the strategy.

This article is the second of a two-part series describing "gaps and contract," a strategy that provides nurses with a mechanism to transfer knowledge from theory into practice in a measurable format. Two universities under contract from the Pennsylvania state cancer plan used this strategy to evaluate the effectiveness of a cancer continuing education program. Two hundred seventy-four (274) contracts from one setting and 205 from a second setting are described. Recommendations for using this strategy to measure the efficacy of cancer continuing education programs are included.     

Mixed models incorporating intra-familial correlation through spatial autoregression

Family researchers are challenged by the need to account for the special forms of statistical dependence that can exist in family data. To address this issue, mixed modeling methods were adapted to account for dependence of continuous outcomes measured across multiple family members. This was accomplished using a spatial autoregressive approach that accounts for dependence on direction as well as on distance apart. For family data, the dimensions underlying direction can correspond to different family members, thereby accounting for different correlations between family members. When the data are also longitudinal, a dimension representing distance apart in time also can be included to account for temporal correlation. Fixed effects involving general linear models can be included as well. Example analyses were conducted to demonstrate the use of the spatial autoregressive approach for modeling intra-familial correlation.     

Coping and acceptance: The greatest challenge for veterans with intestinal stomas

Objective

Intestinal stomas (ostomies) create challenges for veterans. The goal of this qualitative analysis was to understand better patients' perspectives regarding their greatest challenge.

Methods

Ostomates at three Veterans Affairs locations were surveyed using the modified City of Hope Quality of Life—Ostomy questionnaire that contained an open-ended request for respondents to describe their greatest challenge. The response rate was 51% (239 of 467); 68% (163 of 239) completed the open-ended item. Content analysis was performed by an experienced qualitative research team.

Results

Coping and acceptance were the most commonly addressed themes. The most frequently expressed issues and advice were related to a need for positive thinking and insight regarding adjustment over time. Coping strategies included the use of humor, recognition of positive changes resulting from the stoma, and normalization of life with an ostomy.

Conclusions

Coping and acceptance are common themes described by veterans with an intestinal stoma. Health-care providers can assist veterans by utilizing ostomate self-management strategies, experience, and advice.     

Distress with Medication Side Effects among Persons with Severe Mental Illness

We examined prevalence and perceived distress resulting from self-reported side effects (SEs) attributed to psychotropic medications among individuals with severe mental illness participating in a study of consumer-operated services. We examined gender and racial differences using logistic regression, conducted factor analyses of SEs, and examined correlations between distress and self-reported symptoms. Over 90% reported at least one SE, and nearly two-thirds reported a high level of distress with at least one SE. The most distressing SEs reported were embarrassment from weight gain, weight gain, dry mouth, and sedation. The likelihood of distress by particular SEs varied by gender and race. Preliminary results of this work were presented as a poster at the 44th annual meeting of the New Clinical Drug Evaluation Unit of the National Institute of Mental Health, Phoenix, AZ, 2004.     

Comorbidities play a larger role in predicting health-related quality of life compared to having an ostomy

BACKGROUND: Previous research suggests an ostomy worsens health-related quality of life (HR-QOL), but comorbidities also can affect HR-QOL. METHODS: Eligible patients had abdominal operation with ostomy (cases) or similar procedure without ostomy (controls). Patients were recruited for this case-control study from 3 Veterans Affairs hospital medical and pharmacy records. Comorbidities were assessed with Charlson-Deyo Comorbidity Index. Multinomial logistic regression evaluated the impact of comorbidities and having an ostomy on HR-QOL, measured using the Medical Outcomes Study Short Form 36 for Veterans. RESULTS: A total of 237 ostomates (cases) and 268 controls were studied. Average age was 69 years; 64% of cases had colostomy, 36% ileostomy. Twenty-nine percent of patients had a high level of comorbidities. Cases and controls were similar except for reasons for undergoing surgery. High comorbidity was a significant predictor of low HR-QOL in 6 domains of the Short Form 36 for Veterans; having an ostomy was a significant predictor in 4. CONCLUSIONS: High comorbidity significantly influences low HR-QOL and impacted more domains than having an ostomy.     

Models of inter-institutional collaboration to build research capacity for reducing health disparities

Health disparities are inequities in the health of different groups of people that may lead to needless pain, suffering, and premature death. The Yale-Howard Partnership Center on Reducing Health Disparities by Self and Family Management is part of a federally-funded initiative to foster the development of partnerships among researchers, faculty, and students at minority-serving institutions and research-intensive institutions. The goal of the initiative is to maximize the resources available to each of the partnering institutions. The purpose of this article is to describe the models of research collaboration that have emerged from the Yale-Howard Partnership Center on Reducing Health Disparities by Self and Family Management.
