Delirium in elderly people

Retention in medication-assisted treatment among opiate-dependent patients is associated with better outcomes. This systematic review (55 articles, 2010-2014) found wide variability in retention rates (i.e., 19%-94% at 3-month, 46%-92% at 4-month, 3%-88% at 6-month, and 37%-91% at 12-month follow-ups in randomized controlled trials), and identified medication and behavioral therapy factors associated with retention. As expected, patients who received naltrexone or buprenorphine had better retention rates than patients who received a placebo or no medication. Consistent with prior research, methadone was associated with better retention than buprenorphine/naloxone. And, heroin-assisted treatment was associated with better retention than methadone among treatment-refractory patients. Only a single study examined retention in medication-assisted treatment for longer than 1 year, and studies of behavioral therapies may have lacked statistical power; thus, studies with longer-term follow-ups and larger samples are needed. Contingency management showed promise to increase retention, but other behavioral therapies to increase retention, such as supervision of medication consumption, or additional counseling, education, or support, failed to find differences between intervention and control conditions. Promising behavioral therapies to increase retention have yet to be identified.

Retention in medication-assisted treatment for opiate dependence: A systematic review.

Importance Intraoperative electroencephalogram (EEG) waveform suppression, often suggesting excessive general anesthesia, has been associated with postoperative delirium. Objective To assess whether EEG-guided anesthetic administration decreases the incidence of postoperative delirium. Design, Setting, and Participants Randomized clinical trial of 1232 adults aged 60 years and older undergoing major surgery and receiving general anesthesia at Barnes-Jewish Hospital in St Louis. Recruitment was from January 2015 to May 2018, with follow-up until July 2018. Interventions Patients were randomized 1:1 (stratified by cardiac vs noncardiac surgery and positive vs negative recent fall history) to receive EEG-guided anesthetic administration (n = 614) or usual anesthetic care (n = 618). Main Outcomes and Measures The primary outcome was incident delirium during postoperative days 1 through 5. Intraoperative measures included anesthetic concentration, EEG suppression, and hypotension. Adverse events included undesirable intraoperative movement, intraoperative awareness with recall, postoperative nausea and vomiting, medical complications, and death. Results Of the 1232 randomized patients (median age, 69 years [range, 60 to 95]; 563 women [45.7%]), 1213 (98.5%) were assessed for the primary outcome. Delirium during postoperative days 1 to 5 occurred in 157 of 604 patients (26.0%) in the guided group and 140 of 609 patients (23.0%) in the usual care group (difference, 3.0% [95% CI, −2.0% to 8.0%];P = .22). Median end-tidal volatile anesthetic concentration was significantly lower in the guided group than the usual care group (0.69 vs 0.80 minimum alveolar concentration; difference, −0.11 [95% CI, −0.13 to −0.10), and median cumulative time with EEG suppression was significantly less (7 vs 13 minutes; difference, −6.0 [95% CI, −9.9 to −2.1]). There was no significant difference between groups in the median cumulative time with mean arterial pressure below 60 mm Hg (7 vs 7 minutes; difference, 0.0 [95% CI, −1.7 to 1.7]). Undesirable movement occurred in 137 patients (22.3%) in the guided and 95 (15.4%) in the usual care group. No patients reported intraoperative awareness. Postoperative nausea and vomiting was reported in 48 patients (7.8%) in the guided and 55 patients (8.9%) in the usual care group. Serious adverse events were reported in 124 patients (20.2%) in the guided and 130 (21.0%) in the usual care group. Within 30 days of surgery, 4 patients (0.65%) in the guided group and 19 (3.07%) in the usual care group died. Conclusions and Relevance Among older adults undergoing major surgery, EEG-guided anesthetic administration, compared with usual care, did not decrease the incidence of postoperative delirium. This finding does not support the use of EEG-guided anesthetic administration for this indication. Trial Registration ClinicalTrials.gov Identifier:NCT02241655

Delirium prevalence, incidence, and implications for screening in specialist palliative care inpatient settings: A systematic review:

Background: Delirium occurs commonly in hospitaliz ed older patients but is poorly recognized. Although there are a plethora of validated delirium screening tools, it is unclear which tool best suits particular populations. Purpose: To evaluate validation studies of delirium screening tools in non–critically ill hospital inpatients and provide guidance on the choice of screening tool. Methods: The MEDLINE, CINAHL, and PsychInfo databases were searc hed for studies comparing delirium bedside screening tools with either the Diagnostic and Statistical Manual or International Classification of Diseases defined diagnosis of delirium in hospital inpatients. Information was also drawn from conference proceedings and discussion with delirium researchers. Results: Thirty -one studies describing 21 delirium screening tools were included in the systematic review. The majority of studies were conducted across a broad range of inpatient settings internationally in elderly inpatients, including patients with dementia but most excluded nonnative language speakers. Implications: The Confusion Assessment Method w as the most widely used instrument to identify delirium, however, specific training is required to ensure optimum performance. The Delirium Rating Scale and its revised version performed best in the psychogeriatric population but requires an operator with psychiatric training. The Nurses’ Delirium Screening Checklist appears best suited to the surgical and recovery room setting. The Single Question in Delirium shows promise in oncology patients. The Memorial Delirium Assessment Scale, while demonstrating good measures of validity in the surgical and palliative care setting, may be better used a measure of delirium severity. The 4As Test performed well when delirium was superimposed on dementia, but it requires further study.

Delirium Screening: A Systematic Review of Delirium Screening Tools in Hospitalized Patients.

Heroin dependence is a major health and social problem associated with increased morbidity and mortality that adversely affects social circumstances, productivity, and healthcare and law enforcement costs In the UK and many other Western countries, both methadone and buprenorphine are recommended by the relevant agencies for detoxification from heroin and for opioid maintenance therapy However, despite obvious benefits due to its unique pharmacotherapy (eg, greatly reduced risk of overdose), buprenorphine has largely failed to overtake methadone in managing opioid addiction The experience from the developing world (based on data from India) is similar In this article we compare the advantages and disadvantages of the use methadone and buprenorphine for the treatment of opioid addiction from both a developed and developing world perspective; and explore some of the reasons why buprenorphine has not fulfilled the expectations predicted by many in the addictions field

Objectives: Delirium is a common neuropsychiatric condition with many adverse outcomes in elderly populations including death. Despite this, it is often misdiagnosed and mistreated. A number of scales can be used to detect delirium. We review scales that have been used in delirium studies and report their psychometric properties. Method: An extensive MEDLINE database search and subsequent examination of reference lists was conducted to identify the various delirium scales that have been designed, primarily for use in the elderly. Results: Twenty-four scales were identified. Delirium instruments differed according to the classification system they were based on, length of time to administer, the rater and whether they were screening scales or measured symptom severity. The psychometric properties of each scale is reported. Conclusion: A large number of scales exist, but not all are properly evaluated in terms of psychometric properties, and there is not unanimity about which scale is the best. However, a s...

Aims: The aim of this study was to explore the roles of Alcoholics Anonymous (AA) sponsors and to describe the characteristics of a sample of sponsors. Methods: Twenty-eight AA sponsors, recruited using a purposive sampling method, were administered an unstructured qualitative interview and standardized questionnaires. The measurements included: a content analysis of sponsors’ responses; Severity of Alcohol Dependence Questionnaire—Community version (SADQ-C) and Alcoholics Anonymous Affiliation Scale (AAAS). Results: Sample characteristics were as follows: the median length of AA attendance was 9.5 years (range 5–28); the median length of sobriety was 11 years (range 4.5–28); the median number of sponsees per sponsor was 1 but there was a wide range (0–17, interquartile range 3.75); and the sponsors were highly affiliated to AA (median AAAS score 8.75, range 5.5–8.75, maximum possible score 9). Past alcohol dependence scores were surprisingly low: 5 (18%) sponsors had mild, 14 (50%) moderate and 9 (32%) severe dependence according to the SADQ-C (median 26.5, range 11–56). Sponsorship roles were as follows: 16 roles were identified through the initial content analysis. These were distilled into three super-ordinate roles through a thematic analysis: (1) encouraging sponsees to work the programme of AA (doing the 12 steps and engaging in AA activity); (2) support (regular contact, emotional support and practical support); and (3) carrying the message of AA (sharing sponsor's personal experience of recovery with sponsees). Conclusions: The roles identified broadly corresponded with the AA literature delineating the duties of a sponsor. This non-random sample of sponsors was highly engaged in AA activity but only had a past history of moderate alcohol dependence.
