'The patient is my space': hermeneutic investigation of the nurse-patient relationship in critical care.

BACKGROUND: The nurse-patient relationship has been postulated to lie at the core of nursing care. However, it is unclear how this concept applies in critical care, as a great majority of critically ill patients are unable to communicate. AIMS: Through a phenomenological hermeneutical perspective, we aimed to explore intensive care nurses' perceptions and meanings regarding their interpersonal relationship with critically ill individuals. METHODS: A Heideggerian hermeneutical approach was used to design the study and analyse the data, which were collected through repetitive interviews with 12 intensive care nurses. RESULTS: Critical care nurses report to experience deep relationships with patients, which seem to be mediated by the ongoing contact with patients' bodies. These relationships evoke intense feelings of love, empathy and care and affect how nurses perceive and make sense of their role and their world. The identified core theme of their experience is entitled 'syncytium', which describes a network of closely connected cells. According to participants' perceptions, nurse and patient affect each other reciprocally and are mutually dependent upon each other. In Heideggerian terms patients provide nurses with opportunities to experience 'authentic care' and they participate in their 'being-in-the-world', thus they are central in nurses' meanings about their role and existence. Other elicited themes that account for the perceived nurse-patient relationship include the spatiality/temporality of the relationship, nurses' perceptions and meanings attributed to their role and nurses' perceptions of death. CONCLUSIONS: Critical care nurses appear to experience their relationships with patients intensely. These relationships are invested with meanings and elicit powerful feelings over a shared course with patients. Patients are central in nurses' meaning-making process and role perception. RELEVANCE TO CLINICAL PRACTICE: These findings have implications for the educational preparation of critical care nurses and their psychological support.

A critical review of the evidence for nurses as information providers to cancer patients.

AIMS: To review evidence on the role of oncology nurses in the provision of information to cancer patients and to delineate evidence-based implications for clinical practice and research. BACKGROUND: Provision of information is central for the empowerment of patients to participate in their care. There is not enough evidence regarding the nursing role in the information delivery process in cancer patients. DESIGN: Descriptive literature review. METHODS: From January 1990-2008, databases searched included Medline, CINAHL, PubMed, CancerLit and the Cochrane Library. Original research articles addressing the role of nurses in information delivery were included. We explored evidence on: (1) the effectiveness of nurses as information providers, (2) the way patients evaluate nurses' input to information delivery, (3) the extent to which nurses contribute to information delivery to cancer patients and (4) the types of information provided by nurses. RESULTS: The most important findings were: (1) nurses' role as information providers for cancer patients is prominent, especially after the initiation of treatment, (2) specialist nurses are very effective in providing information, (3) no clear evidence exists on how nurses compare with other health-care professionals as information providers and (4) some evidence exists that patients may prefer nurses as information providers at specific times in their treatment and especially in regards to symptom management. CONCLUSION: Well-designed studies provide some evidence that nurses are effective as information providers to cancer patients. Specifically, oncology nurses are able to provide information of both high quality and of appropriate quantity and to assist individuals to interpret information provided by others. RELEVANCE TO CLINICAL PRACTICE: Oncology nurses should be specifically educated and prepared to offer explicit, practical and timely information and they should be trained in interpersonal communication skills, which will increase their ability to comprehend patient information needs.

A randomized controlled trial of an educational intervention on Hellenic nursing staff's knowledge and attitudes on cancer pain management.

The purpose of this randomized controlled study was to explore the effectiveness of an educational intervention on nurses' attitudes and knowledge regarding pain management and to explore associations with nurses' characteristics. A four Solomon group experimental design was employed to assess the effect of the intervention and potential effects of pre-intervention testing. One hundred and twelve nurses were randomized to two intervention and two control groups. The intervention was based on viewing a series of educational videotapes and case scenarios. The Validated Hellenic version of the Nurses Knowledge and Attitudes Survey Regarding Pain (GV-NKASRP) was used. Pre-intervention scores revealed various limitations in regard to pain assessment and management. At the pre-test, the average number of correct answers was 17.58+/-7.58 (45.1%+/-19.3% of total questions). Pre-intervention scores differed significantly among participants with different educational backgrounds (P < 0.0001). A significant effect of pain education on total knowledge scores as well as regarding specific questions was detected. Intervention group participants provided 6.11+/-5.55 additional correct answers (15.66%+/-14.23% improvement, P < 0.0001), and they exhibited significantly improved post-test scores compared to controls (26.49+/-5.24 vs. 18.75+/-4.48; P < 0.0001). A potential negative effect of pre-test on knowledge gain for specific items and for total scores was detected. These findings suggest low pre-test knowledge scores among Hellenic oncology nurses and a significant effect of the intervention.

Altered serum stress neuropeptide levels in critically ill individuals and associations with lymphocyte populations.

OBJECTIVE: Potential physiological correlates of stress and the role of stress neuropeptides, other than those of the hypothalamic-pituitary-adrenal axis, in critical illness have not been addressed. We investigated: (a) serum levels of stress neuropeptides (ACTH, substance P (SP), neuropeptide Y (NPY), cortisol, prolactin) in critically ill individuals compared to matched controls, (b) associations with lymphocyte counts, (c) associations among stress neuropeptide levels, and (d) associations with perceived intensity of stress, critical illness severity and survival. METHODS: Correlational design with repeated measures. Thirty-six critically ill patients were followed up for 14 days compared to 36 healthy matched controls. Stress was assessed by the ICUESS scale. Correlations, cross-sectional comparisons and multiple regression models were pursued. RESULTS: For the first time, we report lower SP (Difference of means (DM) = 2928-3286 ng/ml, p < 0.001) and NPY (DM = 0.77-0.83 ng/ml, p < 0.0001) levels in critically ill individuals compared to controls. Cortisol levels were higher (DM = 140-173 ng/ml, p<0.0001) and lymphocyte population counts (p < 0.002) were lower in patients throughout the study. NPY levels associated with lymphocyte (r = 0.411-0.664, p < 0.04), T-lymphocyte (r = 0.403-0.781, p< 0.05), T-helper (r = 0.492-0.690, p < 0.03) and T-cytotoxic cell populations (r = 0.39-0.740, p < 0.03). On day 1, cortisol levels exhibited associations with lymphocyte (r = -0.452, p = 0.01), T-cell (r = -0.446, p = 0.02), T-helper (r = -0.428, p = 0.026) and T-cytotoxic cells ( r = -0.426, p = 0.027). ACTH levels associated with NK cell counts (r = 0.326-0.441, p < 0.05). Associations among stress neuropeptides levels were observed throughout (p < 0.05). ACTH levels associated with disease severity (r = 0.340-0.387, p < 0.005). A trend for an association between ACTH levels and intensity of stress was noted (r = 0.340, p = 0.057). CONCLUSION: The significantly lowered NPY and SP levels and the associations with cortisol, ACTH and lymphocytes suggest that the role of these peptides in critical illness merit further investigation. Future studies need to address associations between these neuropeptides and functional immune cell responses and inflammatory markers in critical illness.
