The Impact of Pain Assessment on Critically Ill Patients’ Outcomes: A Systematic Review

In critically ill patients, pain is a major problem. Efficient pain management depends on a systematic, comprehensive assessment of pain. We aimed to review and synthesize current evidence on the impact of a systematic approach to pain assessment on critically ill patients’ outcomes. A systematic review of published studies (CINAHL, PUBMED, SCOPUS, EMBASE, and COCHRANE databases) with predetermined eligibility criteria was undertaken. Methodological quality was assessed by the EPHPP quality assessment tool. A total of 10 eligible studies were identified. Due to big heterogeneity, quantitative synthesis was not feasible. Most studies indicated the frequency, duration of pain assessment, and types of pain assessment tools. Methodological quality assessment yielded “strong” ratings for 5/10 and “weak” ratings for 3/10 studies. Implementation of systematic approaches to pain assessment appears to associate with more frequent documented reports of pain and more efficient decisions for pain management. There was evidence of favorable effects on pain intensity, duration of mechanical ventilation, length of ICU stay, mortality, adverse events, and complications. This systematic review demonstrates a link between systematic pain assessment and outcome in critical illness. However, the current level of evidence is insufficient to draw firm conclusions. More high quality randomized clinical studies are needed

Interpersonal touch interventions for patients in intensive care: A design-oriented realist review

Aim: To develop a theoretical framework to inform the design of interpersonal touch interventions intended to reduce stress in adult intensive care unit patients. Design: Realist review with an intervention design‐oriented approach. Methods: We searched CINAHL, MEDLINE, EMBASE, CENTRAL, Web of Science and grey literature sources without date restrictions. Subject experts suggested additional articles. Evidence synthesis drew on diverse sources of literature and was conducted iteratively with theory testing. We consulted stakeholders to focus the review. We performed systematic searches to corroborate our developing theoretical framework. Results: We present a theoretical framework based around six intervention construction principles. Theory testing provided some evidence in favour of treatment repetition, dynamic over static touch and lightening sedation. A lack of empirical evidence was identified for construction principles relating to intensity and positive/negative evaluation of emotional experience, moderate pressure touch for sedated patients and intervention delivery by relatives versus healthcare practitioners

PROFESSIONAL AUTONOMY, COLLABORATION WITH PHYSICIANS, AND MORAL DISTRESS AMONG EUROPEAN INTENSIVE CARE NURSES

Background Discretionary autonomy is a key factor in enhanced patient outcomes and nurses’ work satisfaction. Among nurses, insufficient autonomy can result in moral distress. Objectives To explore levels of autonomy among European critical care nurses and potential associations of autonomy with nurse-physician collaboration, moral distress, and nurses’ characteristics. Methods Descriptive correlational study of a convenience sample of 255 delegates attending a major European critical care conference in 2009. Respondents completed a self-administered questionnaire with validated scales for nurses’ autonomy, nurse-physician collaboration, and moral distress. Results The mean autonomy score (84.26; SD, 11.7; range, 18-108) and the mean composite (frequency and intensity) moral distress score (73.67; SD, 39.19; range, 0-336) were both moderate. The mean collaboration score was 47.85 (SD, 11.63; range, 7-70). Italian and Greek nurses reported significantly lower nurse-physician collaboration than did other nurses (P<.001). Greek and German nurses reported significantly higher moral distress (P<.001). Autonomy scores were associated with nurse-physician collaboration scores (P<.001) and with a higher frequency of moral distress (P=.04). Associations were noted between autonomy and work satisfaction (P=.001). Frequency of moral distress was associated inversely with collaboration (rho=-0.339; P<.001) and autonomy (rho=-0.210; P=.01) and positively with intention to quit (rho=0.257; P=.004). Conclusions In this sample of European intensive care nurses, lower autonomy was associated with increased frequency and intensity of moral distress and lower levels of nurse-physician collaboration.

May BDNF be implicated in the exercise-mediated regulation of inflammation? critical review and synthesis of evidence

Introduction: Exercise attenuates inflammation and enhances levels of brain-derived neurotrophic factor (BDNF). Exercise also enhances parasympathetic tone, although its role in activating the cholinergic anti-inflammatory pathway is unclear. The physiological pathways of exercise’s effect on inflammation are obscure. Aims: To critically review the evidence on the role of BDNF in the anti-inflammatory effects of exercise and its potential involvement in the cholinergic anti-inflammatory pathway. Methods: Critical literature review of studies published in MEDLINE, PubMed, CINAHL, Embase, and Cochrane databases. Results: BDNF is critically involved in the bidirectional signaling between immune and neurosensory cells and in the regulation of parasympathetic system responses. BDNF is also intricately involved in the inflammatory response: inflammation induces BDNF production, and, in turn, BDNF exerts pro- and/or anti-inflammatory effects. Although exercise modulates BDNF and its receptors in lymphocytes, data on BDNF’s immunoregulatory/anti-inflammatory effects in relation to exercise are scarce. Moreover, BDNF increases cholinergic activity and is modulated by parasympathetic system activation. However, its involvement in the cholinergic antiinflammatory pathway has not been investigated. Conclusion: Converging lines of evidence implicate BDNF in exercisemediated regulation of inflammation; however, data are insufficient to draw concrete conclusions. We suggest that there is a need to investigate BDNF as a potential modulator/mediator of the anti-inflammatory effects of exercise and of the cholinergic antiinflammatory pathway during exercise. Such research would have implications for a wide range of inflammatory diseases and for planning targeted exercise protocols
