Long-Term Effects of Postoperative Delirium in Patients Undergoing Cardiac Operation: A Systematic Review.

Delirium is an acute syndrome that involves fluctuating changes in attention and cognition. Although delirium is the most common neurologic complication after cardiac operation, data about its impact on long-term outcomes are lacking. The purpose of this systematic review was to examine the effect of postoperative delirium (PoD) on long-term outcomes, including morbidity, probability of death, cognitive decline, institutionalization, and health-related quality of life (HRQoL) in patients undergoing cardiac operation. After performing this systematic review we determined that PoD after cardiac operation is associated with an increased risk of probability of death and readmission to the hospital and a decrease in cognitive function, overall function, and HRQoL.

The Efficacy and Safety of Megestrol Acetate in Protein-Energy Wasting due to Chronic Kidney Disease: A Systematic Review.

OBJECTIVE: To assess the efficacy and safety of oral megestrol acetate (MA) in the management of protein-energy wasting in patients with chronic kidney disease (CKD). DESIGN: A systematic review of English published literature from 1970 until April 1, 2014. SUBJECTS: All adult patients with CKD including both dialysis and non-dialysis-dependent. INTERVENTION: Oral MA. MAIN OUTCOME MEASURE: Efficacy outcomes included changes in body weight, serum albumin, and appetite. Safety outcomes examined included adverse events (AEs) and deaths. RESULTS: A total of 9 studies met the inclusion criteria. No data on MA in non-dialysis CKD patients were available. Statistically significant increases in body weight (range 1.5-5 kg) were reported in 6 trials. Statistically significant increases in albumin (range of 0.22 g/dL-0.52 g/dL) were observed in 5 trials. Improved appetite was observed in 7 trials. All trials were limited by small sample sizes (range 9-32 subjects), short duration (range 8-24 weeks), a high degree of bias, and absence of clinical outcomes such as quality of life or hospitalizations. Forty-seven AEs were reported and included overhydration/excessive fluid gain, diarrhea, hyperglycemia, excessive weight gain, suppressed cortisol levels, thrombophlebitis, nausea/vomiting, confusion/hallucinations, vaginal bleeding, headache/dizziness, and elevated lactate dehydrogenase. There were 26 discontinuations due to death. CONCLUSION: The current evidence for treatment with MA in patients receiving dialysis is sparse with few high-quality trials. The safety of using MA beyond 24 weeks is unknown, and use of MA is associated with significant AEs. At this time, oral MA should be used with significant caution, and only when other treatment options are unavailable.

Emergency department staff attitudes towards mental health consumers: a literature review and thematic content analysis.

Visits to the emergency department (ED) for mental health reasons account for 10-15% of all visits. Consumers of mental health ED services, however, report that they often feel sent to the back of the queue and that their mental health concerns are not taken seriously, suggesting that societal stigma has impacted their care in the ED. In this study, we systematically explore the research concerning the attitudes of ED professional staff towards those who present with issues related to mental health. Four themes emerge from the literature: consumer perspectives, whose tenor is generally one of negativity; staff-reported attitudes and influencing factors, such as age, experience, and confidence in working with mental health presentations; the environmental climate of the ED, which might not be conducive to good mental health care; and interventions that have been used to evaluate changes in attitudes.

What your patient reads: creating a value-added tool for physicians.

Through a number of media sources, today's consumers have unprecedented access to health information of varying reliability and authority. Empowered by this information, patients are more involved in their health care decisions and more willing to question physicians' advice. This poses a challenge for physicians who must now find time to read mass media health reports in addition to medical research. In order to help physicians with this task, librarians at the University of Manitoba Health Sciences Libraries created What Your Patient Reads - one-page summaries of health-related media reports supplemented with references to evidence-based medical literature.

Methods for the best evidence synthesis on neck pain and its associated disorders: the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders.

STUDY DESIGN: Best evidence synthesis. OBJECTIVE: To provide a detailed description of the methods undertaken in a systematic search and perform a best evidence synthesis on the frequency, determinants, assessment, interventions, course and prognosis of neck pain, and its associated disorders. SUMMARY OF BACKGROUND DATA: Neck pain is an important cause of health burden; however, the published information is vast, and stakeholders would benefit from a summary of the best evidence. METHODS: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders conducted a systematic search and critical review of the literature published between 1980 and 2006 to assemble the best evidence on neck pain. Citations were screened for relevance to the Neck Pain Task Force mandate, using a priori criteria, and relevant studies were critically reviewed for their internal scientific validity. Findings from studies meeting criteria for scientific validity were synthesized into a best evidence synthesis. RESULTS: We found 31,878 citations, of which 1203 were relevant to the mandate of the Neck Pain Task Force. After critical review, 552 studies (46%) were judged scientifically admissible and were compiled into the best evidence synthesis. CONCLUSION: The Bone and Joint Decade 2000-2010 Task Force on Neck Pain and its Associated Disorders undertook a best evidence synthesis to establish a baseline of the current best evidence on the epidemiology, assessment and classification of neck pain, as well as interventions and prognosis for this symptom. This article reports the methods used and the outcomes from the review. We found that 46% of the research literature was of acceptable scientific quality to inform clinical practice, policy-making, and future research.

Triaging suicidal patients: sifting through the evidence.

The triaging of individuals who present to general hospital emergency departments with suicidal thoughts and behaviours is especially challenging and fraught with uncertainty. Although the suicide literature is vast, and risk factor research has a long history, there is a dearth of articles that address the "point of care" factors that need to be considered in triaging a suicidal patient. In order to address this dilemma for nurses performing the triage function, this paper is a targeted review of the suicide risk factor literature designed to discern factors that may have implications for making a triage determination with the intent of improving the accuracy and quality of triage for suicidal patients. Contextual and compositional factors suggesting long-term risk; situational, precipitating, factors that may impact one's immediate risk; and cues and clues to imminent risk are presented along with evidence-based suggestions for assessment and safety.

Systematic search and review procedures: results of the WHO Collaborating Centre Task Force on Mild Traumatic Brain Injury.

The WHO Collaborating Centre for Neurotrauma Task Force on Mild Traumatic Brain Injury performed a comprehensive search and critical review of the literature published between 1980 and 2002 to assemble the best evidence on the epidemiology, diagnosis, prognosis and treatment of mild traumatic brain injury. Our primary sources of literature were Medline, Cinahl, PsycINFO and Embase. Citations were screened for relevance to mild traumatic brain injury, using a priori criteria, and relevant studies were critically reviewed for scientific merit. We identified 38,806 citations, of which 671 studies were judged relevant to the mandate of the task force. These, plus 70 studies found by hand-searching reference lists and 2 original research reports performed as part of the task force mandate were subjected to critical reviews. After review, 313 (42%) were accepted on scientific merit and comprise our best-evidence synthesis. Ninety percent of the literature on mild traumatic brain injury was found in Medline and another 5% in PsycINFO.
