Postoperative delirium (PD) relates to increased morbidity -associated with prolonged hospital stay, institutionalization and persistent functional and cognitive decline- poor long term outcome and higher perioperative mortality. Aim of this literature review is to identify established risk factors for PD and to categorize them according timing of occurrence (pre, intra and post operative), and clinical impact (Odds ratio [OR], % increase in incidence of PD).

Source of information:  medical literature databases (medline and embase) were searched for published manuscripts on "postoperative delirium". Predictors and preoperative risk factors for PD were categorized into 4 groups: demographics; co morbidities; surgery and anesthesia-related (age, education, laboratory anomalies, smoking habits, benzodiazepines premedication, cardiac and thoracic surgery, etc). Intra operative risk factors for PD were categorized into 2 groups: surgery and anesthesia-related (anemia, duration and type of surgery, selected opioid, intraoperative hypotension, etc). Post operative risk factors and precipitating factors include various pathophysiological and environmental conditions, (i.e., ICU admission, low cardiac output requiring inotropes infusion; new onset atrial fibrillation; persistent hypoxia or hypercarbia; use of narcotic analgesics, delayed ambulation, inadequate nutritional status; sensory deprivation, etc). In conclusion, the effective identification, prevention and treatment of pre, intra and postoperative risk factors are the cornerstones for the prevention of PD. A dedicated perioperative care path that encompasses a tailored selection of drugs used perioperatively, the appropriate anesthesia strategy, qualified nursing surveillance, systematic use of diagnostic tools and accurate staff communication reduces the incidence and clinical impact of PD.

Methods:  Data from a previously described screening cohort of the Pharmacological Management of Delirium trial was analyzed. Richmond Agitation-Sedation Scale (RASS) and Confusion Assessment Method for the ICU (CAM-ICU) were assessed twice daily. We defined: Any delirium (positive CAM-ICU at any time during ICU stay) and ICU-acquired delirium (1st CAM-ICU negative with a subsequent positive CAM-ICU). Mixed-effects logistic regression models were used to test for differences.

Results:  2742 patient admissions were included. Delirium occurred in 16.5%, any delirium decreased [22.7% to 10.2% (p < 0.01)], and ICU-acquired delirium decreased [8.4% to 4.4% (p = 0.01)]. Coma decreased from 24% to 17.4% (p = 0.04). Later ICU years and higher mean RASS scores were associated with lower odds of delirium.

Alcohol abuse is a common condition that has been associated with severe impairments in social functioning and medical problems. As high as 20% of the population have been noted to exhibit alcohol abuse during their lifespan. More than 50% of those with a history of alcohol abuse can exhibit alcohol withdrawal symptoms at discontinuing or decreasing their alcohol use. However, only a few (3% to 5%) exhibit symptoms of severe alcohol withdrawal with profound confusion, autonomic hyperactivity, and cardiovascular collapse. This is defined as alcohol withdrawal delirium, more commonly known as delirium tremens (DT). Delirium tremens was first recognized as a disorder attributed to excessive alcohol abuse in 1813. It is now commonly known to occur as early as 48 hours after abrupt cessation of alcohol in those with chronic abuse and can last up to 5 days. It has an anticipated mortality of up to 37% without appropriate treatment. It is crucial to identify early signs of withdrawal because it can become fatal. This activity examines when delirium tremens should be considered and how to properly evaluate for it. This activity highlights the role of the interprofessional team in caring for patients with delirium tremens.

Delirium, a syndrome characterized by an acute change in attention, awareness and cognition, is caused by a medical condition that cannot be better explained by a pre-existing neurocognitive disorder. Multiple predisposing factors (for example, pre-existing cognitive impairment) and precipitating factors (for example, urinary tract infection) for delirium have been described, with most patients having both types. Because multiple factors are implicated in the aetiology of delirium, there are likely several neurobiological processes that contribute to delirium pathogenesis, including neuroinflammation, brain vascular dysfunction, altered brain metabolism, neurotransmitter imbalance and impaired neuronal network connectivity. The Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) is the most commonly used diagnostic system upon which a reference standard diagnosis is made, although many other delirium screening tools have been developed given the impracticality of using the DSM-5 in many settings. Pharmacological treatments for delirium (such as antipsychotic drugs) are not effective, reflecting substantial gaps in our understanding of its pathophysiology. Currently, the best management strategies are multidomain interventions that focus on treating precipitating conditions, medication review, managing distress, mitigating complications and maintaining engagement to environmental issues. The effective implementation of delirium detection, treatment and prevention strategies remains a major challenge for health-care organizations globally.

The DSM-5 criteria for delirium are broad, with these criteria also often applying in numerous other acute neurological conditions. Therefore, research on delirium is typically performed in patients with non-neurological conditions, although these findings might be extrapolated to patients with primary brain injury. Most patients with delirium have been exposed to a variety of both predisposing and precipitating risk factors and it can be difficult to assign one specific cause in a given case of delirium11.

Despite being described in Roman times, delirium has received little attention until the past three to four decades12,13. Although funding for delirium research and public awareness of this condition have increased, they still lag far behind other important public health-care issues14. In this Primer, we describe the epidemiology of delirium in different populations, the current understanding of delirium pathophysiology, and the various criteria and tools for the diagnosis, screening and monitoring of delirium. Furthermore, we describe approaches to manage delirium, its effects on patient quality of life (QOL) and provide an outlook on future research priorities and treatment options.

Epidemiological studies of delirium provide accurate estimates when standard diagnostic criteria or validated detection tools are used and when the study sample is representative of the population being studied15. Here, we present data from high-quality studies or systematic reviews that adhere to established standards of reporting, such as the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist.

The prevalence of delirium in infants, children and adolescents is less well understood. Studies from Europe and the USA report prevalence estimates of delirium in children and adolescents ranging from 4% to almost 50% in critically ill children and adolescents30,31,32,33,34,35. In one study from the USA, more than half of infants under 2 years of age experienced delirium while critically ill36. The prevalence of subsyndromal delirium is highly variable and depends on the population being studied and which delirium definition is used. However, in one study from North America, almost two-thirds of adults over 65 years of age who were admitted to an inpatient medical or geriatric service had subsyndromal delirium7.

The risk of delirium is determined by predisposing risk factors (that is, the background characteristics of patients) and precipitating risk factors (that is, acute insults, injury or drugs). Predisposing risk factors for delirium include increased age, cognitive impairment (such as dementia37 or developmental delay38), frailty, comorbidities (including cardiovascular and renal disease), depression or other psychiatric illness39,40, alcohol use, poor nutritional status41,42, and visual and hearing impairment18,27. Total risk depends on the number of risk factors in each individual and, where applicable, their severity; for example, frailty, which typically encompasses a number of risk factors, is strongly associated with delirium risk43,44, and the degree of cognitive impairment shows a strong linear association with delirium risk45. Furthermore, neuroimaging studies indicate that the risk of delirium might be higher in individuals with greater cerebral atrophy and/or greater white matter disease46,47. Genetic studies have not identified consistent candidate genes associated with delirium risk but these studies are few and underpowered48,49.

Precipitating factors for delirium span a wide range of different kinds of insults, including, amongst others, acute medical illness (such as sepsis, hypoglycaemia, stroke and liver failure), trauma (such as fractures or head injury), surgery, dehydration and psychological stress17,27. Typically, more than one precipitating factor is present in patients50,51. In addition, drug use and withdrawal and medication changes are associated with delirium. Of note, benzodiazepines, dihydropyridines (L-type calcium channel blockers typically used in the treatment of hypertension), antihistamines and opioids may convey the highest risk of delirium, although insufficiently managed pain may itself be a risk factor52,53; however, the exact relationship between pain medication, pain management and delirium risk remains unclear. In addition to common premorbid factors, specific health-care setting-related factors, such as mechanical ventilation54,55,56,57,58,59, are risk factors for hospital-acquired delirium (Fig. 1). Many of these factors may coexist in different health-care settings. be457b7860
