Contradictions and communication strategies during end-of-life decision making in the intensive care unit.

PURPOSE: The aim of this study was to identify inherent tensions that arose during family conferences in the intensive care unit, and the communication strategies clinicians used in response. MATERIALS AND METHODS: We identified 51 clinician-family conferences in the intensive care unit from 4 hospitals in which the attending physician believed discussion of withdrawing life-sustaining treatments or delivery of bad news would occur. The communication between clinicians and family members was analyzed using a dialectic perspective. RESULTS: The tension of choosing whether to "let the patient die now" versus to "not let the patient die now" was the central contradiction within the conferences. Under this overriding theme were 5 categories: killing or allowing to die; death as a benefit or a burden; honoring the patient's wishes or following the family's wishes; weighing contradictory versions of the patient's wishes; and choosing an individual family member as decision maker or the family as a unit as decision maker. In response to these contradictions, clinicians used 2 clusters of communication strategies: decision-centered strategies and information-seeking strategies. CONCLUSIONS: This study offered insights into end-of-life decision making, prompting clinicians to be conscious of the contradictions that arise and to use specific strategies to address these contradictions in their communication with families.

Surgical hand scrubs in relation to microbial counts: systematic literature review.

AIM: This paper reports a systematic review whose objective was to determine the effectiveness of surgical hand scrubs in relation to bacterial growth on the hands of operating room staff members. BACKGROUND: Despite the need for surgical hand scrubs, evidence shows that frequent and prolonged use of antiseptics and brushes may damage the skin. Consequently, lesions may appear, become more heavily colonized by microorganisms and increase the risk of transmitting infection to patients. Recommendations about surgical hand scrubs vary widely and their effectiveness in relation to microbial counts is unknown. METHOD: A variety of healthcare databases were searched covering the period between January 1990 and December 2004. Based on selection criteria, the abstracts of studies identified were checked to determine whether they fulfilled the inclusion criteria. All studies were assessed as having adequate methodological quality. Using Cochrane Review Manager 4.2 software, weighted mean difference and 95% confidence intervals were calculated. FINDINGS: Three studies were included in this review. Two studies compared the effectiveness of surgical hand scrubs using an alcohol-based product and a 6-minute scrub using 4% chlorhexidine gluconate; meta-analysis showed a statistically significant difference (weighted mean difference = -0.63, 95% confidence intervals = -0.99 to -0.27, P = 0.0006). One study compared the effectiveness of 2- and 3-minute surgical hand scrubs using 4% chlorhexidine gluconate; meta-analysis showed no difference (weighted mean difference = 0.29, 95% confidence intervals = -0.13 to 0.71, P = 0.18). CONCLUSION: Surgical hand scrubs using an alcohol-based product were more effective than a 6-minute scrub using 4% chlorhexidine gluconate. There is no evidence to support a 2-minute surgical hand scrub as being more effective than a 3-minute one using 4% chlorhexidine gluconate.

Graduated compression stockings as prophylaxis for flight-related venous thrombosis: systematic literature review.

AIM: This paper reports a systematic review whose objective was to evaluate the effectiveness of graduated compression stockings as prophylaxis for flight-related venous thrombosis, including deep vein thrombosis and superficial venous thrombosis, after air travel in the general population. BACKGROUND: Despite the extended history of the use of graduated compression stockings, their application to prevent flight-related thrombosis was not explored until flight-related thrombosis was perceived as a preventable illness. Even now, their effectiveness in preventing flight-related thrombosis remains unresolved. METHODS: Generic terms including stocking/s, sock/s, or hosiery/hosieries were used to search a variety of electronic databases. Based on the selection criteria, decisions regarding inclusion and exclusion of primary studies were made. Using a meta-analysis software program, relative risk for the incidence of deep vein thrombosis, superficial venous thrombosis, and intention-to-treat analysis was calculated. RESULTS: A total of nine randomized controlled trials were included. In the treatment group, two of 1237 participants developed deep vein thrombosis in comparison with 46 of 1245 in the control group. The weighted relative risk for deep vein thrombosis was 0.08, with fixed 95% confidence interval 0.03-0.23. In the treatment group, four of 826 participants developed superficial venous thrombosis in comparison with seven of 823 in the control group. The weighted relative risk for superficial venous thrombosis was 0.67. with fixed 95% confidence interval 0.24-1.87 (non-significant difference). Using intention-to-treat analysis, the risk for participants in the treatment group was 0.53 times as great as that for those in the control group. CONCLUSIONS: This review demonstrates the effectiveness of medium compression pressure, below-knee graduated compression stockings in preventing flight-related deep vein thrombosis but not superficial venous thrombosis in low-medium- or high-risk participants.

Three approaches to qualitative content analysis.

Content analysis is a widely used qualitative research technique. Rather than being a single method, current applications of content analysis show three distinct approaches: conventional, directed, or summative. All three approaches are used to interpret meaning from the content of text data and, hence, adhere to the naturalistic paradigm. The major differences among the approaches are coding schemes, origins of codes, and threats to trustworthiness. In conventional content analysis, coding categories are derived directly from the text data. With a directed approach, analysis starts with a theory or relevant research findings as guidance for initial codes. A summative content analysis involves counting and comparisons, usually of keywords or content, followed by the interpretation of the underlying context. The authors delineate analytic procedures specific to each approach and techniques addressing trustworthiness with hypothetical examples drawn from the area of end-of-life care.

Effect of reminiscence therapy on depression in older adults: a systematic review.

The objective of this systematic review is to provide healthcare professionals with information to assist in their decision to utilize reminiscence therapy for depression reduction in older adults outside of the primary care setting. Nine reviewed studies that were randomized controlled trials not only varied in person, outcome measurement, control, and exposure/intervention, the results of these studies were also diverse. About half of these studies showed that reminiscence therapy resulted in statistical significantly decrease in depression. Despite that reminiscence therapy requires further testing, it should be considered as a valuable intervention. Future directions of studies on reminiscence therapy are suggested.
