Abstract
BACKGROUND New sleep-inducing drugs (eg, ramelteon, suvorexant, and lemborexant) have been shown to prevent delirium in high-risk groups. However, no single study has simultaneously evaluated the delirium-preventing effects of all novel sleep-inducing drugs in hospitalized patients. Therefore, this study aimed to clarify the relationship between sleep-inducing drugs and delirium prevention in patients hospitalized in general medical-surgical settings for nonpsychiatric conditions who underwent liaison interventions for insomnia. METHODS This retrospective cohort study included patients treated in general medical-surgical settings for nonpsychiatric conditions with consultation-liaison psychiatry consult for insomnia. Delirium was diagnosed by fully certified psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders 5 th edition. The following items were retrospectively examined from medical records as factors related to delirium development: type of sleep-inducing drugs, age, sex, and delirium risk factors. The risk factors of delirium development were calculated using adjusted odds ratios (aORs) via multivariate logistic regression analysis. RESULTS Among the 710 patients analyzed, 257 (36.2%) developed delirium. Suvorexant (aOR, 0.61; 95% confidence interval [CI], 0.40-0.94; P = 0.02) and lemborexant (aOR, 0.23; 95% CI, 0.14-0.39; P < 0.0001) significantly reduced the risk of developing delirium. Benzodiazepines (aOR, 1.90; 95% CI, 1.15-3.13; P = 0.01) significantly increased this risk. Ramelteon (aOR, 1.30; 95% CI, 0.84-2.01; P = 0.24) and Z-drugs (aOR, 1.27; 95% CI, 0.81-1.98; P = 0.30) were not significantly associated with delirium development. CONCLUSIONS The use of suvorexant and lemborexant may prevent delirium in patients with a wide range of medical conditions.

Abstract
Purpose of Review Emergency departments (EDs) are facing an epidemic of overcrowding and ED boarding, particularly of older adults who often present with, or develop, delirium in the ED. Delirium is associated with increased complications, longer hospital length of stay, mortality, and costs to the healthcare system. However, we only have limited knowledge of how to successfully prevent and treat delirium in the ED in a pragmatic, sustainable, and cost-effective way. We present a narrative review of recent literature of delirium prevention and treatment programs in the ED. We aim to describe the components of successful delirium management strategies to be used by EDs in building delirium management programs. Recent Findings We reviewed 10 studies (2005-2023) that report delirium interventions in the ED, and describe the different components of these interventions that have been studied. These interventions included: optimizing hemodynamics and oxygenation, treating pain, hydration and nutrition support, avoiding sedative hypnotics, antipsychotics and anticholinergics, promoting sleep, sensory stimulation, limiting the time spent in the ED, educating providers and staff, and developing multidisciplinary delirium protocols integrated into the electronic health record. Summary Through our narrative review of the recent literature on delirium prevention and treatment programs in the ED, we have identified nine components of successful delirium prevention strategies in the ED. We also discuss three high priority areas for further research including identification of most effective components of delirium prevention strategies, conduct of additional high-quality trials in non-hip.

Assessment and report of individual symptoms in studies of delirium in postoperative populations: a systematic review. Age Ageing 2024; 53:afae077. [PMID: 38640126 PMCID: PMC11028403 DOI: 10.1093/ageing/afae077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2023] [Revised: 03/06/2024] [Indexed: 04/21/2024] Open
Abstract
OBJECTIVES Delirium is most often reported as present or absent. Patients with symptoms falling short of the diagnostic criteria for delirium fall into 'no delirium' or 'control' groups. This binary classification neglects individual symptoms and may be hindering identification of the pathophysiology underlying delirium. This systematic review investigates which individual symptoms of delirium are reported by studies of postoperative delirium in adults. METHODS Medline, EMBASE and Web of Science databases were searched on 03 June 2021 and 06 April 2023. Two reviewers independently examined titles and abstracts. Each paper was screened in duplicate and conflicting decisions settled by consensus discussion. Data were extracted, qualitatively synthesised and narratively reported. All included studies were quality assessed. RESULTS These searches yielded 4,367 results. After title and abstract screening, 694 full-text studies were reviewed, and 62 deemed eligible for inclusion. This review details 11,377 patients including 2,049 patients with delirium. In total, 78 differently described delirium symptoms were reported. The most reported symptoms were inattention (N = 29), disorientation (N = 27), psychomotor agitation/retardation (N = 22), hallucination (N = 22) and memory impairment (N = 18). Notably, psychomotor agitation and hallucinations are not listed in the current Diagnostic and Statistical Manual for Mental Disorders-5-Text Revision delirium definition. CONCLUSIONS The 78 symptoms reported in this systematic review cover domains of attention, awareness, disorientation and other cognitive changes. There is a lack of standardisation of terms, and many recorded symptoms are synonyms of each other. This systematic review provides a library of individual delirium symptoms, which may be used to inform future reporting.

Abstract
BACKGROUND Delirium occurs at high rates among patients in intensive care units and increases the risk of morbidity and mortality. The purpose of this study was to investigate the effects of environmental interventions on delirium. METHODS This prospective cohort study enrolled 192 patients admitted to the surgical intensive care unit (SICU) during the pre-intervention (June 2013 to October 2013) and post-intervention (June 2014 to October 2014) periods. Environmental interventions involved a cognitive assessment, an orientation, and a comfortable environment including proper sleep conditions. The primary outcomes were the prevalence, duration, and onset of delirium. RESULTS There were no statistically significant differences in incidence rate, time of delirium onset, general characteristics, and mortality between the pre-intervention and post-intervention groups. The durations of delirium were 14.4±19.1 and 7.7±7.3 days in the pre-intervention and post-intervention groups, respectively, a significant reduction (P=0.027). The lengths of SICU stay were 20.0±22.9 and 12.6±8.7 days for the pre-intervention and post-intervention groups, respectively, also a significant reduction (P=0.030). CONCLUSIONS The implementation of an environmental intervention program reduced the duration of delirium and length of stay in the SICU for critically ill surgical patients.

Abstract
PURPOSE Anticholinergic (AC) drugs are associated with various determinantal outcomes. Data regarding the effect of AC drugs on mortality among geriatric hip fracture patients are limited and inconsistent. METHODS Using Danish health registries, we identified 31,443 patients aged ≥65 years undergoing hip fracture surgery. AC burden was assessed 90 days before surgery by the Anticholinergic Cognitive Burden (ACB) score and number of AC drugs. Logistic and Cox regression producing odds ratios (OR) and hazard ratios (HR) for 30- and 365- day mortality, adjusting for age, sex, and comorbidities were computed. RESULTS AC drugs were redeemed by 42% of patients. The 30-day mortality increased from 7% for patients with ACB score of 0 to 16% for patients with ACB score of ≥5, corresponding to an adjusted OR 2.5 (CI: 2.0-3.1). The equivalent adjusted HR for 365-mortality was 1.9 (CI: 1.6-2.1). Using count of AC drugs as exposure we found a stepwise increase in ORs and HRs with increased number of AC drugs; Compared to non-users, adjusted ORs for 30-days mortality were 1.6 (CI: 1.4-1.7), 1.9 (CI: 1.7-2.1), and 2.3 (CI: 1.9-2.7) for users of 1, 2 and 3+ AC drugs. HRs for 365-day mortality were 1.4 (CI: 1.3-1.5), 1.6 (CI: 1.5-1.7) and 1.8 (CI: 1.7-2.0). CONCLUSION Use of AC drugs was associated with increased 30-day and 365-day mortality among older adults with hip fracture. Simply counting the number of AC drugs may be a clinically relevant and easy AC risk assessment tool. Continued effort to reduce AC drug-use is relevant.

Abstract
Objective To explore the effect of early intervention for perioperative delirium in older (> 60 years) hip fracture patients. Methods This prospective study enrolled hip fracture patients aged ≥60 years who were admitted into our hospital between July 2011 and August 2019. Hip fractures were classified according to the Arbeitsgemeinschaft für Osteo‐synthesefragen (AO) classification. This study included patients with isolated hip fracture and excluded patients with pathological or peri prosthetic fracture or patients with multiple traumatic injuries and high‐energy trauma. They were randomized to receive conventional orthopedic care group (n = 65) or comprehensive orthopedic care group including preoperative psychological counseling and preventative risperidone (n = 63). Daily assessment was based on patient interview with the CAM‐CR, and delirium was diagnosed by the Delirium Rating Scale (DRS‐R‐98). The rate, severity and duration of perioperative delirium and the length of postoperative stay were analyzed. Results Totally 200 patients were screened for eligibility. Twenty patients were excluded due to alcohol abuse and 40 were excluded because of brain lesions on head CT. In addition, 12 patients were excluded because of impaired cognition. Finally 128 patients were enrolled. Their mean age was 75.3 ± 2.2 years for the comprehensive orthopedic care group and 73.5 ± 6.1 years for the conventional orthopedic care group, and 53.9% of the patients were female. Sixty‐eight (53.1%) patients had intertrochanteric fracture, 39.8% patients had femoral head fracture, and 7.0% patients had subtrochanteric fracture. In addition, 58.6% patients underwent internal fixation and 41.4% patients received arthroplasty. In this study, 63 patients were randomized to the comprehensive orthopedic care group and 65 patients to the conventional orthopedic care group. The two groups were comparable in demographic and baseline characteristics (P > 0.05). The rate of perioperative delirium was significantly lower in the comprehensive care group vs the conventional care group (15.9% vs. 30.8%; P < 0.05). The comprehensive care group had significantly reduced length of postoperative hospital stay vs the conventional care group (11.3 ± 2.5 days vs. 14.2 ± 2.2 days, P < 0.01). The mean DRS‐R‐98 score was 7.1 ± 2.7 for the comprehensive care group, and was significantly lower than that of the conventional orthopedic care group (11.2 ± 3.0; P < 0.05). Conclusions Our early intervention may reduce the incidence of perioperative delirium in elderly hip fracture patients (>60 years).

Abstract
Introduction Postoperative delirium (POD) is a serious complication occurring in 4–53.3%
of geriatric patients undergoing surgeries for hip fracture. Incidence of
hip fractures is projected to grow 11.9% from 258,000 in 2010 to 289,000 in
2030 based on 1990 to 2010 data. As prevalence of hip fractures is projected
to increase, POD is also anticipated to increase. Signficance Postoperative delirium remains the most common complication of emergency hip
fracture surgery leading to high morbidity and mortality rates despite
significant research conducted regarding this topic. This study reviews
literature from 1990 to 2021 regarding POD in geriatric hip fracture
management. Results Potentially modifiable and non-modifiable risk factors for developing POD
include, but are not limited to, male gender, older age, multiple
comorbidities, specific comorbidities (dementia, cognitive impairment,
diabetes, vision impairment, and abnormal blood pressure), low BMI,
preoperative malnutrition, low albumin, low hematocrit, blunted preoperative
cytokines, emergency surgery, time to admission and surgery, preoperative
medical treatment, polypharmacy, delirium-inducing medications, fever,
anesthesia time, and sedation depth and type. Although the pathophysiology
remains unclear, the leading theories suggest neurotransmitter imbalance,
inflammation, and electrolyte or metabolic derangements as the underlying
cause of POD. POD is associated with increased length of hospital stay,
cost, morbidity, and mortality. Prevention and early recognition are key
factors in managing POD. Methods to reduce POD include utilizing
interdisciplinary teams, educational programs for healthcare professionals,
reducing narcotic use, avoiding delirium-inducing medications, and
multimodal pain control. Conclusion While POD is a known complication after hip fracture surgery, further
exploration in prevention is needed. Early identification of risk factors is
imperative to prevent POD in geriatric patients. Early prevention will
enhance delivery of health care both pre- and post-operatively leading to
the best possible surgical outcome and better quality of life after hip
fracture treatment.

Abstract
BACKGROUND Delirium is common in elderly patients with hip fracture. Although several multicomponent care pathways have been developed, few nurse-led perioperative multicomponent programs have been evaluated. AIMS The current study aimed to evaluate the effect of a nurse-led perioperative multicomponent interdisciplinary program in preventing postoperative delirium in elderly patients with hip fracture. METHOD The participants in the usual care group were recruited from March 2012 to February 2013, and these in the experimental group were recruited from May 2013 to June 2014. The participants in the usual care group (n = 174) received usual medical and nursing care from admission to hospital discharge and the participants in the experimental group (n = 192) received the nurse-led perioperative multicomponent interdisciplinary intervention. The STROBE checklist was used to report this study. RESULTS There were no statistical differences between the two cohorts in terms of the baseline data such as gender, age, fracture type, and so on. The experimental group had a lower incidence of delirium and postoperative hypoxia than the usual care group. No statistical differences in terms of delirium severity, delirium duration, and mean hospitalization length were observed. CONCLUSIONS The nurse-led perioperative multicomponent interdisciplinary program described in the current study is feasible and effective in reducing the incidence of postoperative delirium in elderly patients with hip fracture.

Abstract
INTRODUCTION Postoperative delirium (POD) is one of the most frequent complication after surgery in elderly patients, and is associated with increased morbidity and mortality, prolonged length of stay, cognitive and functional decline leading to loss of autonomy, and important additional healthcare costs. Perioperative inflammatory stress is a key element in POD genesis. Melatonin exhibits antioxidative and immune-modulatory proprieties that are promising concerning delirium prevention, but in perioperative context literature are scarce and conflicting. We hypothesise that perioperative melatonin can reduce the incidence of POD. METHODS AND ANALYSIS The DELIRLESS trial is a prospective, national multicentric, phase III, superiority, comparative randomised (1:1) double-blind clinical trial. Among patients aged 70 or older, hospitalised and scheduled for surgery of a severe fracture of a lower limb, 718 will be randomly allocated to receive either melatonin 4 mg per os or placebo, every night from anaesthesiologist preoperative consultation and up to 5 days after surgery. The primary outcome is POD incidence measured by either the French validated translation of the Confusion Assessment Method (CAM) score for patients hospitalised in surgery, or CAM-ICU score for patients hospitalised in ICU (Intensive Care Unit). Daily delirium assessment will take place during 10 days after surgery, or until the end of hospital stay if it is shorter. POD cumulative incidence function will be compared at day 10 between the two randomised arms in a competing risks framework, using the Fine and Grey model with death as a competing risk of delirium. ETHICS AND DISSEMINATION The DELIRLESS trial has been approved by an independent ethics committee the Comité de Protection des Personnes (CPP) Sud-Est (ref CPP2020-18-99 2019-003210-14) for all study centres. Participant recruitment begins in December 2020. Results will be published in international peer-reviewed medical journals. TRIAL REGISTRATION NUMBER NCT04335968, first posted 7 April 2020. PROTOCOL VERSION IDENTIFIER N°3-0, 3 May 2021.

Abstract
BACKGROUND Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention. OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU). SEARCH METHODS We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search. SELECTION CRITERIA We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium. DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium. MAIN RESULTS We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies. Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain. Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I2 = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias). There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I2 = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision). No studies of multicomponent interventions reported data on new diagnoses of dementia. Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I2 = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I2=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I2=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited. Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm. Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial. Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I2 = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias). Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention. AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

J Clin Nurs 2021; 31:1082-1094. [PMID: 34302312 DOI: 10.1111/jocn.15973] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 06/20/2021] [Accepted: 07/05/2021] [Indexed: 01/09/2023]
Abstract
AIMS AND OBJECTIVES This study aimed to investigate the effectiveness of a delirium prevention care protocol on pain, functional status, sleep quality and delirium prevention in patients with hip fractures. BACKGROUND The development of delirium following hip fracture is common among older patients. According to the National Institute for Health and Care Excellence, 30% of delirium cases are preventable. The prevention of delirium, a multifactorial syndrome, can be achieved through a multicomponent care protocol that targets specific risk factors for delirium. DESIGN A randomised controlled study was conducted according to the CONSORT 2010 guidelines. The Clinical Trial Registry number is NCT04188795. METHODS A total of 84 patients were assigned to two groups by block randomisation. The intervention group (n = 41) received nursing care according to a protocol and the control group (n = 43) received standard nursing care. Study data were collected using the demographic information form, the Confusion Assessment Method-Intensive Care Unit (CAM-ICU), the Barthel Index, the Mini Nutritional Assessment-short form and the Richards-Campbell Sleep Questionnaire (RCSQ). The pain of the patients was assessed by using a Visual Analog Scale (VAS). RESULTS The mean age of the patients was 80.6 years (standard deviation 8.0; range 65.0- 97.5 years), and the percentage of the male patients were 36.3%. No statistically significant differences were found between the groups in terms of pain and functional status in the preoperative period, on the first postoperative day, or in the predischarge period (p > 0.05 for each). The sleep quality of patients in the intervention group was significantly better than in the control group for all three time measurements (p < 0.05 for each). While 15% of patients in the control group developed delirium, no patient in the intervention group developed delirium (x2 =6.486, p = 0.026). CONCLUSION This study demonstrated that a delirium prevention care protocol may reduce the incidence of delirium and improve sleep quality. RELEVANCE TO PRACTICE The study highlighted that nurses can contribute to preventing patients' delirium using nonpharmacologic and independent nursing interventions.

Br J Anaesth 2021; 127:102-109. [PMID: 34074525 PMCID: PMC8258970 DOI: 10.1016/j.bja.2021.03.033] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 03/06/2021] [Accepted: 03/18/2021] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND Frailty has been associated with increased incidence of postoperative delirium and mortality. We hypothesised that postoperative delirium mediates a clinically significant (≥1%) percentage of the effect of frailty on mortality in older orthopaedic trauma patients. METHODS This was a single-centre, retrospective observational study including 558 adults 65 yr and older, who presented with an extremity fracture requiring hospitalisation without initial ICU admission. We used causal statistical inference methods to estimate the relationships between frailty, postoperative delirium, and mortality. RESULTS In the cohort, 180-day mortality rate was 6.5% (36/558). Frail and prefrail patients comprised 23% and 39%, respectively, of the study cohort. Frailty was associated with increased 180 day mortality from 1.4% to 12.2% (11% difference; 95% confidence interval [CI], 8.4-13.6), which translated statistically into an 88.7% (79.9-94.3%) direct effect and an 11.3% (5.7-20.1%) postoperative delirium mediated effect. Prefrailty was also associated with increased 180 day mortality from 1.4% to 4.4% (2.9% difference; 2.4-3.4), which was translated into a 92.5% (83.8-99.9%) direct effect and a 7.5% (0.1-16.2%) postoperative delirium mediated effect. CONCLUSIONS Frailty is associated with increased postoperative mortality, and delirium might mediate a clinically significant, but small percentage of this effect. Studies should assess whether, in patients with frailty, attempts to mitigate delirium might decrease postoperative mortality.

Comparing the rates of delirium in patients receiving usual care vs alternative care: A systematic review and meta-analysis. Int J Clin Pract 2021; 75:e13859. [PMID: 33236458 DOI: 10.1111/ijcp.13859] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2020] [Revised: 11/10/2020] [Accepted: 11/22/2020] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Delirium is an acute condition that occurs in hospitalised patients and leads to poor patient outcomes that can last long term. Therefore, the importance of prevention is undeniable and adopting new models of care for at-risk patients should be prioritised. OBJECTIVES This systematic review and meta-analysis will assess the effectiveness of different interventions designed to prevent or manage delirium in acutely unwell hospitalised patients. METHODS MEDLINE, EMBASE, PsycINFO, OpenGrey, Web of Science and reference lists of journals were searched. Eligible studies reported on incidence or duration of delirium, used a validated delirium diagnostic tool and compared an intervention to either a control or another intervention group. Meta-analyses were conducted, and GRADEpro software was used to assess the certainty of evidence. This review is registered on PROSPERO. RESULTS A total of 59 studies were included and 33 were eligible for meta-analysis. Delirium incidence was most significantly reduced by non-pharmacological multicomponent interventions compared with usual care, with pooled risk ratios of 0.57 (95% CI: 0.44 to 0.73, 10 randomised controlled trials) and 0.47 (95% CI: 0.35 to 0.64, six observational studies). Single-component interventions did not significantly reduce delirium incidence compared with usual care in seven randomised trials (risk ratio = 0.92, 95% CI: 0.81 to 1.04). The most effective single-component intervention in reducing delirium incidence was a hospital-at-home intervention (risk ratio = 0.29, 95% CI: 0.09 to 0.87). CONCLUSIONS Non-pharmacological multicomponent interventions are effective in preventing delirium; however, the same cannot be said for other interventions because of uncertain results. There is some evidence that providing multicomponent interventions in patients' homes is more effective than in a hospital setting. Therefore, researching the benefits of hospital-at-home interventions in delirium prevention is recommended.

Abstract
BACKGROUND Older persons with a suspected hip fracture and suffering considerable pain are common patients in the emergency medical services (EMS). Pain treatment needs to be improved and fascia iliaca compartment block (FICB) can be one option. The purpose of this paper was to analyse prehospital pain in patients with a suspected hip fracture under EMS care and to compare standard treatment and FICB. METHODS An evaluation of a retrospective case-control study comprising 135 patients from a pilot project with FICB in an EMS organisation in Sweden. The control patients were matched with FICB patients. Pain was assessed on the arrival of the EMS and on arrival in hospital. RESULTS In all, 27 patients received FICB and 108 had standard pain treatment. There was a significant reduction in pain in both groups. However, there was a more marked reduction in pain among patients who received FICB than in the control group. So, for static pain, 56% experienced a reduction in pain in the FICB group versus 30% among controls (p < 0.01). The corresponding values for dynamic pain were 85% and 59% (p < 0.01). CONCLUSION FICB can be a good supplement to standard prehospital pain treatment in patients with suspected hip fractures.

Abstract
Post-operative delirium after lung transplantation is common. Its associations with health-related quality of life (HRQL), depression, and mortality remains unknown. In 236 lung transplant recipients, HRQL and depressive symptoms were assessed as part of a structured survey battery before and after transplantation. Surveys included the Geriatric Depressive Scale (GDS) and Short Form 12 (SF12). Delirium was assessed throughout the post-operative intensive care unit (ICU) stay with Confusion Assessment Method for ICU. Delirium and mortality data were extracted from electronic medical records. We examined associations between delirium and changes in depressive symptoms and HRQL using linear mixed effects models and association between delirium and mortality with Cox-proportional hazard models. Post-operative delirium occurred in 34 participants (14%). Delirium was associated with attenuated improvements in SF12-PCS (difference ₋4.0; 95%CI: -7.4, -0.7) but not SF12-MCS (difference 2.2; 95%CI: -0.7,5.7) or GDS (difference ₋0.4; 95%CI: -1.5,0.7). Thirty-two participants died during the study period. Delirium was associated with increased adjusted hazard risk of mortality (HR 17.9, 95%CI: 4.4,72.5). Delirium after lung transplantation identifies a group at increased risk for poorer HRQL and death within the first post-operative year. Further studies should investigate potential causal links between delirium, and poorer HRQL and mortality risk after lung transplantation.

Abstract
Postoperative delirium (POD) is an acute neurological condition associated with changes in cognition and attention and disorganised thinking. Although delirium can affect patients from any age group, it is common in older patients and could lead to a longer hospital stay and a higher risks of mortality. This article presents findings from a literature review that identifies various strategies used by health professionals globally to prevent POD. A database search resulted in 25 articles that met the inclusion criteria. Thematic analysis and coding were used to combine recurrent ideas that emerged from the literature. Three themes were identified: early identification and screening, modifiable risk factors, and preventive interventions. Further research focusing on education and improving awareness about POD among nurses is essential.

Abstract
Background Delirium is one of the prevalent complications of post open heart surgery. The present research aimed to assess the effect of multi-component interventions on the incidence rate, severity, and duration of post open heart surgery delirium among hospitalized patients. Methods In this quasi-experimental study, 96 patients under open heart surgery were selected using convenience sampling and divided into a control and an intervention group. The interventions included the patients’ preoperative education, nurses’ education, and in-ward environmental interventions. The demographic information and Mini-Mental State Examination (MMSE) questionnaires were completed a day before surgery. The patients in both groups were also surveyed after extubation until the fourth day post operation using Delirium Observation Screening (DOS) scale considering the incidence, severity, and duration of delirium. The data were analyzed using the SPSS statistical software, version 20. Results The incidence rate of delirium was 14.6 and 6.2% in the control and intervention groups, respectively (p > 0.05). Besides, the mean severity of delirium was 0.53 in the control group and 0.40 in the intervention group (p > 0.05). Finally, the mean duration of delirium was 4.5 and 3.25 h in the two groups, respectively (p > 0.05). Conclusions Since prevention of delirium can play a considerable role in the patients’ recovery after heart surgery, it is necessary to carry out some measures to prevent such complications. Even though the interventions performed in this study did not cause significant changes in this regard, the results suggested that prevention interventions should be performed with stronger and more integrated planning for achieving better outcomes.

Abstract
Delirium is common in older emergency department (ED) patients. Although associated with significant morbidity and mortality, it often goes unrecognized. A consistent approach to evaluation of mental status, including use of validated tools, is key to diagnosing delirium. Identification of the precipitating event requires thorough evaluation, including detailed history, medication reconciliation, physical examination, and medical work-up, for causes of delirium. Management is aimed at identifying and treating the underlying cause. Meaningful improvements in delirium care can be achieved when prevention, identification, and management of older delirious ED patients is integrated by physicians and corresponding frameworks implemented at the health system level.

Abstract
Patients admitted with COVID-19 can develop delirium due to predisposing factors, isolation, and the illness itself. Standard delirium prevention methods focus on interaction and stimulation. It can be challenging to deliver these methods of care in COVID settings where it is necessary to increase patient isolation. This paper presents a typical clinical vignette of representative patients in a tertiary care hospital and how a medical team modified an evidence-based delirium prevention model to deliver high-quality care to COVID-19 patients. The implemented model focuses on four areas of delirium-prevention: Mobility, Sleep, Cognitive Stimulation, and Nutrition. Future studies will be needed to track quantitative outcome measures.

Higher versus lower mean arterial pressure target management in older patients having non-cardiothoracic surgery: A prospective randomized controlled trial. J Clin Anesth 2021; 69:110150. [PMID: 33418429 DOI: 10.1016/j.jclinane.2020.110150] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Revised: 11/01/2020] [Accepted: 11/21/2020] [Indexed: 02/08/2023]
Abstract
STUDY OBJECTIVE This study aimed to evaluate the effects of low versus high mean arterial pressure (MAP) levels on the incidence of postoperative delirium during non-cardiothoracic surgery in older patients. DESIGN Multicenter, randomized, parallel-controlled, open-label, and assessor-blinded clinical trial. SETTING University hospital. PATIENTS Three hundred twenty-two patients aged ≥65 with an American Society of Anesthesiologists physical status of I-II who underwent non-cardiothoracic surgery with general anaesthesia. INTERVENTIONS Participants were randomly assigned into a low-level MAP (60-70 mmHg) or high-level MAP (90-100 mmHg) group during general anaesthesia. The study was conducted from November 2016 to February 2020. Participants were older patients having non-cardiothoracic surgery. The follow-up period ranged from 1 to 7 days after surgery. The primary outcome was the incidence of postoperative delirium. MAIN RESULTS In total, 322 patients were included and randomized; 298 completed in-hospital delirium assessments [median (interquartile range) age, 73 (68-77) years; 173 (58.1%) women]. Fifty-four (18.1%) patients total, including 36 (24.5%) and 18 (11.9%) in the low-level and high-level MAP groups [relative risk (RR) 0.48, 95% confidence interval (CI) 0.25 to 0.87, P = 0.02], respectively, experienced postoperative delirium. The adjusted RR was 0.34 (95% CI 0.16 to 0.70, P < 0.01) in the multiple regression analysis. High-level MAP was associated with a shorter delirium span and a higher intraoperative urine volume than low-level MAP. CONCLUSIONS In older patients during non-cardiothoracic surgery, high-level blood pressure management might help reduce the incidence of postoperative delirium.

Abstract
BACKGROUND Older adult delirium is often unrecognized in the emergency department (ED), yet the most compelling research questions to overcome knowledge-to-practice deficits remain undefined. The Geriatric Emergency care Applied Research (GEAR) Network was organized to identify and prioritize delirium clinical questions. METHODS GEAR identified and engaged 49 transdisciplinary stakeholders including emergency physicians, geriatricians, nurses, social workers, pharmacists, and patient advocates. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews, clinical questions were derived, medical librarian electronic searches were conducted, and applicable research evidence was synthesized for ED delirium detection, prevention, and management. The scoping review served as the foundation for a consensus conference to identify the highest priority research foci. RESULTS In the scoping review, 27 delirium detection "instruments" were described in 48 ED studies and used variable criterion standards with the result of delirium prevalence ranging from 6% to 38%. Clinician gestalt was the most common "instrument" evaluated with sensitivity ranging from 0% to 81% and specificity from 65% to 100%. For delirium management, 15 relevant studies were identified, including one randomized controlled trial. Some intervention studies targeted clinicians via education and others used clinical pathways. Three medications were evaluated to reduce or prevent ED delirium. No intervention consistently prevented or treated delirium. After reviewing the scoping review results, the GEAR stakeholders identified ED delirium prevention interventions not reliant on additional nurse or physician effort as the highest priority research. CONCLUSIONS Transdisciplinary stakeholders prioritize ED delirium prevention studies that are not reliant on health care worker tasks instead of alternative research directions such as defining etiologic delirium phenotypes to target prevention or intervention strategies.

Abstract
PURPOSE Little is known about the factors predicting balance in hip fracture patients. The aim of this retrospective observational study was to assess balance before and after inpatient rehabilitation and, secondarily, to identify factors predicting the balance levels in older hip fracture patients after motor rehabilitation. METHODS Data were collected in 124 hip fracture patients over a 2-year period. All patients underwent a standard motor rehabilitation program. A modified version of Berg Balance Scale (BBS) score after rehabilitation, daily gain and percentage of improvement in BBS were the outcome measures. Multivariate regression analysis was performed to identify the predictors of balance. RESULTS The mean BBS score was 8.33 ± 7.23 at admission and 21.79 ± 12.15 at the end of rehabilitation (p < 0.001). The daily gain in BBS score was 0.39 ± 0.31 and the percent improvement was 32.28 ± 23.04%. Standing with one foot in front and standing on one foot were the BBS items with the lowest score at discharge and the lowest daily gain and percent improvement. The Cognitive-Functional Independence Measure (cognitive-FIM), hip muscles strength, and Katz index at discharge had moderate-to-strong relationships with final score, daily gain and percentage of improvement in BBS. Cognitive-FIM was a predictor of final BBS score (beta 0.49, p < 0.001), daily gain in BBS (beta 0.34, p < 0.001) and percent improvement in BBS (beta 0.44, p < 0.001). Conversely, hip muscles strength was a predictor of final BBS score (beta 0.32, p = 0.001), and Cumulative Illness Rating Scale severity, a predictor of daily gain in BBS (beta -0.29, p = 0.001). The R2 value of the models were, respectively, 0.39, 0.23, and 0.19. CONCLUSIONS Cognitive function, comorbidities and hip muscles strength are important predictors of balance in hip fracture patients. Knowledge of these specific factors can be useful for physicians to identify patients needing specific rehabilitation programs for balance.

Abstract
STUDY OBJECTIVE An estimated 80% of older people undergoing surgery develop postoperative delirium (POD) making them a high-risk group. Research in this area is growing fast but there is no established consensus on strategies for POD prevention or management. A systematic review and meta-analysis were conducted to synthesise data on clinical interventions used to reduce POD among older people undergoing elective and emergency surgery. METHODS A range of database searches generated 336 papers. A total of 25 studies met the inclusion criteria and were assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The studies were undertaken across the world. RESULTS This review identified a range of intervention approaches: comparisons between anaesthetic and sedatives agents, medication-specific interventions and multidisciplinary models of care. Results found more consistencies across multidisciplinary interventions than the pharmacological interventions. In pooled analyses, haloperidol (OR 0.74; 95% CI (confidence interval) 0.44, 1.26) was not statistically significantly associated with reduced POD incidence any more than a placebo. CONCLUSION There is a need to implement multidisciplinary interventions, as well as collaboration between clinicians on pre- and postoperative care practices regarding pharmacological interventions to more effectively reduce and manage POD in older people.

Abstract
Postoperative delirium is a geriatric syndrome that manifests as changes in cognition, attention, and levels of consciousness after surgery. It occurs in up to 50% of patients after major surgery and is associated with adverse outcomes, including increased hospital length of stay, higher cost of care, higher rates of institutionalization after discharge, and higher rates of readmission. Furthermore, it is associated with functional decline and cognitive impairments after surgery. As the age and medical complexity of our surgical population increases, practitioners need the skills to identify and prevent delirium in this high-risk population. Because delirium is a common and consequential postoperative complication, there has been an abundance of recent research focused on delirium, conducted by clinicians from a variety of specialties. There have also been several reviews and recommendation statements; however, these have not been based on robust evidence. The Sixth Perioperative Quality Initiative (POQI-6) consensus conference brought together a team of multidisciplinary experts to formally survey and evaluate the literature on postoperative delirium prevention and provide evidence-based recommendations using an iterative Delphi process and Grading of Recommendations Assessment, Development and Evaluation (GRADE) Criteria for evaluating biomedical literature.

Abstract
BACKGROUND Impaired cognition is a major risk factor for perioperative delirium. It is essential to provide good pain control in patients with hip fractures and especially important in patients with severely impaired cognitive status, as they receive less pain medication, have poorer mobility, poorer quality of life and higher mortality than patients with intact cognition. The purpose of this study was to examine the association between preoperative pain management with nerve blocks and cognitive status in patients with hip fractures during the perioperative period. METHODS One hundred and twenty-seven patients with hip fractures participating in a double-blind, randomised, controlled trial were included in this study. At hospital admission, a low-dose fascia iliaca compartment block (FICB) was administered as a supplement to regular analgesia. Cognitive status was registered on arrival at hospital before FICB and on the first postoperative day using the Short Portable Mental Status Questionnaire. RESULTS Changes in cognitive status from arrival at hospital to the first postoperative day showed a positive, albeit not significant, trend in favour of the intervention group. The results also showed that patients with no or a moderate cognitive impairment received 50% more prehospital pain medication than patients with a severe cognitive impairment. FICB was well tolerated in patients with hip fractures. CONCLUSION Fascia iliaca compartment block given to patients with hip fractures did not affect cognitive status in this study. Patients with a cognitive impairment may receive inadequate pain relief after hip fracture and this discrimination needs to be addressed in further studies.

Abstract
BACKGROUND Each hospital day of delirium incurs greater healthcare costs, higher levels of care, greater staff burden, and higher complication rates. Accordingly, administrators are incentivized to identify models of care that reduce delirium rates and associated costs. PURPOSE We present a systematic review and meta-analysis of delirium prevention models of care. DATA SOURCES Ovid MEDLINE, CINAHL, Cochrane Database of Systematic Reviews, EMBASE, and PsycINFO. STUDY SELECTION Eligible models of care were defined as provider-oriented interventions involving revision of professional roles, multidisciplinary teams, and service integration. Included studies implemented multidomain, multicomponent interventions, used a validated delirium instrument, and enrolled a control group to evaluate efficacy or effectiveness. DATA EXTRACTION We extracted data on study design; Population, model of care, outcomes, and results. DATA SYNTHESIS A total of 15 studies were included. All but two studies reported reduction in delirium or its duration, and 11 studies reported statistically significant improvements. Using random effects models, the pooled odds ratios of delirium incidence were 0.56 (95% CI: 0.37-0.85) from three randomized controlled trials, 0.63 (95% CI 0.37-1.07) from four pre-post intervention studies, and 0.79 (95% CI: 0.46-1.37) from three additional nonrandomized studies. CONCLUSIONS Several models of care can prevent delirium. In general, higher quality studies were more likely to demonstrate statistical significance of an effect. The diverse models of care included here explored interventions adapted to specific care settings, especially by addressing setting-specific delirium risk factors. These care models illustrate a range of promising strategies that deserve growing recognition, refinement, and implementation.

Abstract
INTRODUCTION Early assessment of hip fracture patients' cognitive function is important for preventing pre- and postoperative complications. The aim of this study was twofold: (1) to assess prehospital cognitive function in hip fracture patients and establish whether cognitive status differs pre- and postoperatively between prehospital fast track care (PFTC) and the traditional emergency department (ED) pathway and (2) whether preoperative cognitive function is associated with postoperative mortality and activities of daily living (ADL) ability. METHODS Three hundred and ninety one hip fracture patients were prospectively included. The Short Portable Mental Status Questionnaire (SPMSQ) was used prehospital, at the orthopaedic ward and three days postoperatively. ADL was followed up after four months. RESULTS No difference in patients' cognitive function was observed between PFTC and ED. Four-month mortality was 37% for patients with dementia, 21% for those with cognitive impairment and 10% for patients without cognitive impariment. Only 26% of patients with dementia and 47% with cognitive impairment had full ADL ability, compared with 70% of patients with intact cognitive function (p < 0.001). CONCLUSION PFTC did not influence hip fracture patients' cognitive function. Patients with prehospital cognitive impairment had a poor outcome in terms of mortality and ADL, indicating the need for special care interventions.

Effects of bupivacaine or levobupivacaine on cerebral oxygenation during spinal anesthesia in elderly patients undergoing orthopedic surgery for hip fracture: a randomized controlled trial. BMC Anesthesiol 2019; 19:17. [PMID: 30704463 PMCID: PMC6357488 DOI: 10.1186/s12871-019-0682-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2018] [Accepted: 01/07/2019] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Bupivacaine and levobupivacaine have similar pharmacokinetic and pharmacodynamic characteristics, and are used regularly in spinal anesthesia. Whether potential differences in their hemodynamic and anesthetic profiles could determine a differential risk of complications in elderly subjects, is controversial. The main objective was to compare the effects of intrathecally administered levobupivacaine (LB) versus bupivacaine (B), on regional cerebral O2 saturation during spinal anesthesia, cognitive status and neurological complications in elderly patients undergoing surgery for hip fracture. METHODS This was a randomized, controlled, single blind study. 58 patients aged 70 or older undergoing surgery for hip fracture with spinal anesthesia were allocated with a 1:1 ratio to receive LB or B, combined with fentanyl 15 μg, by intrathecal route. The primary outcome was the proportion of intraoperative time with regional cerebral desaturation (≥20% reduction in regional cerebral oxygen saturation from baseline), monitored by near -infrared spectroscopy. Secondary endpoints included hemodynamic parameters, level of sensory and motor block, changes in Short Portable Mental Status Questionnaire (SPMSQ), and neurological complications. RESULTS The mean percentage of intraoperative time with desaturation in the B group was 6.1% (SD: 17.5) and 4.7% (SD: 11.9) in the left and right hemisphere respectively; in the LB group the mean was 4.8% (SD: 11.4) in the left hemisphere and 2.4% (SD: 8.3) in the right one. No statistically significant differences were found between treatment groups. The level of sensory block at the start of surgery was lower for LB than for B (Th10 vs Th8, p:0.047) and motor block at 15 min was lower for LB (2.5 vs 3, p:0.009). No differences in postoperative SPMSQ were observed. Neurological complications such as confusional state, agitation or disorientation were reported in 50% of patients in the B group and 21.4% of patients in the LB group, p = 0.05. CONCLUSIONS No statistically significant differences in regional cerebral oxygen saturation or hemodynamic parameters were observed between both treatment groups. Bupivacaine and levobupivacaine differed in sensory and motor block achieved. While no differences were observed in cognitive impairment measured by the SPMSQ between treatment groups neurological complications reported by the physician were more frequent with bupivacaine.

Surgical delay is a risk factor of delirium in hip fracture patients with mild-moderate cognitive impairment. Aging Clin Exp Res 2019; 31:41-47.

Abstract
AIM To investigate the relationship between onset of delirium and time to surgery in hip fracture (HF) patients with a different degree of cognitive impairment. METHODS Retrospective analysis of a prospective database of 939 older adults, aged ≥ 75 years admitted with a fragility HF. Subjects underwent a Comprehensive Geriatric Assessment on admission, evaluating health status, prefracture functional status in basic and instrumental activities of daily living, and walking ability. According to the Short Portable Mental Status Questionnaire score, patients were stratified into three categories: cognitively healthy (0-2 errors), mildly to moderately impaired (3-7 errors) and severely impaired (8-10 errors). Time to surgery (from admission) was expressed as days. The occurrence of delirium was ascertained daily by Confusion Assessment Method. RESULTS Two hundred ninety-two (31.1%) patients experienced delirium during in-hospital stay. They were older, with a higher degree of comorbidity and functional impairment compared to patients without delirium. In multivariate analysis, surgical delay resulted a significant independent risk factor for delirium (HR 1.11, 95% CI 1.01-1.24), along with age, prefracture functional disability and cognitive impairment. When the analysis was performed accounting for the cognitive categories, surgical delay demonstrated to increase the risk of delirium only in the subcategory of mildly to moderately impaired patients, while no significant effect was demonstrated in patients cognitively healthy or severely impaired. CONCLUSIONS The study supports the concept that older adults with HF should undergo surgery quickly. Patients with mild-to-moderate cognitive impairment should be primarily considered as the best target for interventions aiming to reduce time to surgery.

Abstract
OBJECTIVE Older patients with hip fractures who are undergoing surgery are at high risk of significant mortality and morbidity including postoperative delirium. It is unclear whether different types of anaesthesia may reduce the incidence of postoperative delirium. This systematic review will investigate the impact of anaesthetic technique on postoperative delirium. Other outcomes included mortality, length of stay, complications and functional outcomes. DESIGN Systematic review of randomised controlled trials and non-randomised controlled studies. DATA SOURCES Bibliographic databases were searched from inception to June 2018. Web of Science and ZETOC databases were searched for conference proceedings. Reference lists of relevant articles were checked, and clinical trial registers were searched to identify ongoing trials. ELIGIBILITY CRITERIA Studies were eligible if general and regional anaesthesia were compared in patients (aged 60 and over) undergoing hip fracture surgery, reporting primary outcome of postoperative delirium and secondary outcomes of mortality, length of hospital stay, adverse events, functional outcomes, discharge location and quality of life. Exclusion criteria were anaesthetic technique or drug not considered current standard practice; patients undergoing hip fracture surgery alongside other surgery and uncontrolled studies. RESULTS One hundred and four studies were included. There was no evidence to suggest that anaesthesia type influences postoperative delirium or mortality. Some studies suggested a small reduction in length of hospital stay with regional anaesthesia. There was some evidence to suggest that respiratory complications and intraoperative hypotension were more common with general anaesthesia. Heterogeneity precluded meta-analysis. All findings were described narratively and data were presented where possible in forest plots for illustrative purposes. CONCLUSIONS While there was no evidence to suggest that anaesthesia types influence postoperative delirium, the evidence base is lacking. There is a need to ascertain the impact of type of anaesthesia on outcomes with an adequately powered, methodologically rigorous study. PROSPERO REGISTRATION NUMBER CRD42015020166.

Abstract
Background Delirium in older hospitalised patients is a common and serious disorder. Polypharmacy and certain medications are risk factors for developing delirium. A medication review could benefit older hospitalised patients with delirium. Objectives (1) Evaluate the effects of medication review on length of delirium, length of hospital stay, mortality, and discharge destination; and (2) describe and analyse the proposed changes to medication and its implementation by the treating physician. Setting The study was conducted at Maastricht University Medical Centre+. Methods We compared two cohorts of older patients with delirium: the first cohort from before introducing the medication review, and a second cohort 5 months after introduction of the medication review. Data were extracted from the patients’ digital medical records. Results A significant interaction effect of cohort and number of medications taken by the patient was found for duration of delirium: patients from the second cohort taking between zero and six medications had significantly shorter delirious episodes than patients in the first cohort. This effect bordered on significance for patients taking between seven and 11 medications, but disappeared for patients taking 12 or more medications. No other statistically significant differences were found between the cohorts. The proposed changes in medication were implemented for 71% of the patients. Conclusion A medication review seems to significantly decrease the length of an older patient’s delirious episode. Given the clinical relevance of these findings, we advise medication reviews for all older patients who are delirious or are at risk of developing delirium.

Abstract
BACKGROUND Delirium is a common complication among elderly patients undergoing total joint arthroplasty (TJA). Its incidence has been reported from 4% to 53%. The Centers for Medicare and Medicaid Services consider delirium following TJA a "never-event." The purpose of this study is to evaluate a simple perioperative protocol used to identify delirium risk patients and prevent its incidence following TJA. METHODS Our group developed a protocol to identify and prevent delirium in patients undergoing TJA. All patients were screened and scored in the preoperative assessment, on criteria such as age, history of forgetfulness, history of agitation or visual hallucinations, history of falls, history of postoperative confusion, and inability to perform higher brain functions. Patients were scored on performance in a simple mental examination. The patients were classified as low, medium, or high risk. Patients who were identified as high risk were enrolled in a delirium avoidance protocol that minimized narcotics and emphasized nursing involvement and fluids administration. RESULTS Five of 7659 (0.065%) consecutive TJA patients from 2010 to 2015 developed delirium. A total of 422 patients were identified as high risk. All 5 patients who suffered delirium were within the high risk group. No low or medium risk patients suffered a delirium complication. Three (0.039%) patients suffered drug-induced delirium, 1 (0.013%) had delirium related to alcohol withdrawal, and 1 (0.013%) had delirium after a systemic infection. CONCLUSION This protocol is effective in identifying patients at high delirium risk and diminishing the incidence of this complication by utilizing a simple screening tool and perioperative protocol.

Abstract
UNLABELLED ABSTRACTBackground:Delirium is the most frequent complication among the hospitalized elderly with hip fracture. Although, delirium is associated with longer hospital stay, higher mortality rates, worse functional outcomes, and higher institutionalization rates yet health service planners have hugely ignored its existence. This review aims to identify the effectiveness of multicomponent interventions to prevent delirium in hospitalized elderly patients with hip fracture. METHODS This review includes experimental, non-experimental, and observational studies. Electronic searches were conducted in MEDLINE, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, Embase, and Web of science. RESULTS After inclusion and exclusion criteria were applied, nine full text articles were included in the review. The studies reported the following effect on delirium: We pooled data regarding incidence of delirium from the three RCTs. The effect was in favor of the intervention group (odds ratio 0.64, 95% CI 0.46-0.87). All three RCTs reported that duration of delirium was shorter in the intervention group than in the usual care group (mean 2.9 vs. 3.1 days, median 3 vs. 4 days, median 5.0 vs. 10.2 days). Four other studies reported on the duration of delirium with Milisen and colleagues reported shorter duration of delirium within the intervention group. Four studies reported on severity of delirium with two research groups reporting significant results. CONCLUSION Early engagement of multidisciplinary staff who addresses the risk factors of delirium as soon as the patient presents to the acute care environment is the key element of a successful delirium prevention program. Once delirium had developed, the multicomponent interventions did not appear to make a difference to the duration or severity of delirium.

Abstract
BACKGROUND Aging populations are at increased risk of postoperative complications. New methods to provide care for older people recovering from surgery may reduce surgery-related complications. Comprehensive geriatric assessment (CGA) has been shown to improve some outcomes for medical patients, such as enabling them to continue living at home, and has been proposed to have positive impacts for surgical patients. CGA is a coordinated, multidisciplinary collaboration that assesses the medical, psychosocial and functional capabilities and limitations of an older person, with the goal of establishing a treatment plan and long-term follow-up. OBJECTIVES To assess the effectiveness of CGA interventions compared to standard care on the postoperative outcomes of older people admitted to hospital for surgical care. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL and two clinical trials registers on 13 January 2017. We also searched grey literature for additional citations. SELECTION CRITERIA Randomized trials of people undergoing surgery aged 65 years and over comparing CGA with usual surgical care and reporting any of our primary (mortality and discharge to an increased level of care) or secondary (length of stay, re-admission, total cost and postoperative complication) outcomes. We excluded studies if the participants did not receive a complete CGA, did not undergo surgery, and if the study recruited participants aged less than 65 years or from a setting other than an acute care hospital. DATA COLLECTION AND ANALYSIS Two review authors independently screened, assessed risk of bias, extracted data and assessed certainty of evidence from identified articles. We expressed dichotomous treatment effects as risk ratio (RR) with 95% confidence intervals and continuous outcomes as mean difference (MD). MAIN RESULTS We included eight randomised trials, seven recruited people recovering from a hip fracture (N = 1583) and one elective surgical oncology trial (N = 260), conducted in North America and Europe. For two trials CGA was done pre-operatively and postoperatively for the remaining. Six trials had adequate randomization, five had low risk of performance bias and four had low risk of detection bias. Blinding of participants was not possible. All eight trials had low attrition rates and seven reported all expected outcomes.CGA probably reduces mortality in older people with hip fracture (RR 0.85, 95% CI 0.68 to 1.05; 5 trials, 1316 participants, I² = 0%; moderate-certainty evidence). The intervention reduces discharge to an increased level of care (RR 0.71, 95% CI 0.55 to 0.92; 5 trials, 941 participants, I² = 0%; high-certainty evidence).Length of stay was highly heterogeneous, with mean difference between participants allocated to the intervention and the control groups ranging between -12.8 and 8.3 days. CGA probably leads to slightly reduced length of stay (4 trials, 841 participants, moderate-certainty evidence). The intervention probably makes little or no difference in re-admission rates (RR 1.00, 95% CI 0.76 to 1.32; 3 trials, 741 participants, I² = 37%; moderate-certainty evidence).CGA probably slightly reduces total cost (1 trial, 397 participants, moderate-certainty evidence). The intervention may make little or no difference for major postoperative complications (2 trials, 579 participants, low-certainty evidence) and delirium rates (RR 0.75, 95% CI 0.60 to 0.94, 3 trials, 705 participants, I² = 0%; low-certainty evidence). AUTHORS' CONCLUSIONS There is evidence that CGA can improve outcomes in people with hip fracture. There are not enough studies to determine when CGA is most effective in relation to surgical intervention or if CGA is effective in surgical patients presenting with conditions other than hip fracture.

Abstract
Dexmedetomidine is a highly selective α2-adrenergic agonist with analgesic and sedative properties. In the United States, the Food and Drug Administration approved the use of the drug for short-lasting sedation (24 h) in intensive care units (ICUs) in patients undergoing mechanical ventilation and endotracheal intubation. In October 2008, the Food and Drug Administration extended use of the drug for the sedation of nonintubated patients before and during surgical and nonsurgical procedures. In the European Union, the European Medicine Agency approved the use of dexmedetomidine in September 2011 with a single recognized indication: ICU adult patients requiring mild sedation and awakening in response to verbal stimulus. At present, the use of dexmedetomidine for sedation outside the ICU remains an off-label indication. The benefits of dexmedetomidine in critically ill patients and in cardiac, electrophysiology-related, vascular, and thoracic procedures are discussed.

Abstract
Delirium is the most common psychiatric syndrome found in the general hospital setting, with an incidence as high as 87% in the acute care setting. Delirium is a neurobehavioral syndrome caused by the transient disruption of normal neuronal activity secondary to systemic disturbances. The development of delirium is associated with increased morbidity, mortality, cost of care, hospital-acquired complications, placement in specialized intermediate and long-term care facilities, slower rate of recovery, poor functional and cognitive recovery, decreased quality of life, and prolonged hospital stays. This article discusses the epidemiology, known etiological factors, presentation and characteristics, prevention, management, and impact of delirium.

Abstract
INTRODUCTION The escalation in the prevalence of obesity throughout the world has led to an upsurge in the number of obese surgical patients to whom perioperative care needs to be delivered. SOURCES OF DATA After determining the scope of the review, the authors used PubMed with select phrases encompassing the words in the scope. Both preclinical and clinical reports were considered. AREAS OF AGREEMENT There were no controversies regarding preoperative management and the intraoperative care of the obese surgical patient. AREAS OF CONTROVERSY Is there a healthy obese state that gives rise to the obesity paradox regarding postoperative complications? GROWING POINTS This review considers how to prepare for and manage the obese surgical patient through the entire spectrum, from preoperative assessment to possible postoperative intensive care. AREAS TIMELY FOR DEVELOPING RESEARCH What results in an obese patient developing 'unhealthy' obesity?

Abstract
A 75-year-old man is admitted for scheduled major abdominal surgery. He is functionally independent, with mild forgetfulness. His intraoperative course is uneventful, but on postoperative day 2, severe confusion and agitation develop. What is going on? How would you manage this patient’s care? Could his condition have been prevented?
