Abstract: To explore factors associated with decision-making of nurses and doctors in prescribing and administering as required antipsychotic medications to older people with delirium. Qualitative descriptive. Two acute care hospital organisations in Melbourne, Australia. Nurses and doctors were invited to participate. Semi-structured focus groups and in idual interviews were conducted between May 2019 and March 2020. Interviews were audio-recorded and transcribed verbatim. Data were analysed using thematic analysis. Participants were 42 health professionals n=25 nurses and n=17 doctors. Themes relating to decisions to use antipsychotic medication were: safety a last resort nursing workload a dilemma to medicate and anticipating worsening behaviours . Nurses and doctors described experiencing pressures when trying to manage hyperactive behaviours. Safety was a major concern leading to the decision to use antipsychotics. Antipsychotics were often used as chemical restraints to ‘sedate’ a patient with delirium because nurses ‘can’t do their job’. Results also indicated that nurses had influence over doctors’ decisions despite nurses being unaware of this influence. Health professionals’ descriptions are illustrated in a decision-making flowchart that identifies how nurses and doctors navigated decisions regarding prescription and administration of antipsychotic medications. The decision to prescribe and administer antipsychotic medications for people with delirium is complex as nurses and doctors must navigate multiple factors before making the decision. Collaborative support and multidisciplinary teamwork are required by both nurses and doctors to optimally care for people with delirium. Decision-making support for nurses and doctors may also help to navigate the multiple factors that influence the decision to prescribe antipsychotics.

Abstract: Delirium is a serious neurocognitive disorder among surgical patients in the post-anaesthetic care unit (PACU). Despite the development of screening tools to identify delirium, it is not clear which tool is the most accurate and reliable in assessing delirium in the PACU. To examine the diagnostic accuracy of delirium screening tools used in the PACU. A systematic literature search of CINAHL, MEDLINE, Embase, PsycINFO and Scopus was conducted, using MeSH terms and relevant keywords, from databases establishment to 23 April 2021. Studies were assessed for methodological quality using the Standards for Reporting of Diagnostic Accuracy Studies (STARD) tool. A total of 1503 studies were screened from the database search, four studies met the inclusion criteria for this review. Six delirium screening tools used in the PACU were identified in the selected studies. Three studies evaluated screening tools in adult surgical patients without cognitive impairment and dementia. Two studies evaluated screening tools among patients who were scheduled for elective surgery. Review results indicated that two tools, the 4A's test (4AT sensitivity 96% specificity 99%) and the 3 min diagnostic interview for the Confusion Assessment Method (3D-CAM sensitivity 100% specificity 88%), had greatest validity and reliability as a screening tool for detecting delirium in the PACU. Results indicate the 4AT and the 3D-CAM are most accurate screening tools to detect delirium in the PACU. Further research is required to validate those tools among a broader surgical population, including patients with cognitive impairment, dementia and those undergoing emergency surgical procedures.

Abstract: Patients present to EDs with various medication-related problems (MRPs). MRPs are also associated with ED care, occurring during ED presentation or shortly afterwards. The aim of the present study is to describe the prevalence and nature of MRPs that occur prior to, during or shortly after leaving ED. We undertook a prospective, observational study in nine Australian EDs. Blocks of 10 consecutive adult patients who were not seen by a pharmacist in ED and who presented at pre-specified times were identified. Within 1 week of ED discharge, a pharmacist interviewed patients and undertook a medical record review to determine their medication history, patients' understanding of treatment, potential MRP risk factors and manage any identified MRPs. A total of 904 patients were recruited: 14.8% aged ≥80 years, 18.9% taking more than eight regular medications 581 MRPs were identified 287 (49.4%, 95% confidence interval [CI] 45.3-53.5%) of moderate-high significance. Most highly significant MRPs involved high-risk medications, particularly strong opioids, insulin and anti-coagulants. The most common types of MRPs were prescribing errors (46.8%), patient adherence/knowledge issues (31.2%) and adverse drug reactions (7.4%). Of all patients, 381 (42.1%, 95% CI 38.9-45.5%) had at least one MRP 31.4% (95% CI 28.4-34.6%) had MRPs that could be identified or managed by screening at ED presentation and 12.4% (95% CI 10.4-14.8%) had MRPs that could be identified or managed by screening at ED discharge. Patients experienced a range of MRPs throughout the ED continuum of care. From these data, screening tools will be developed so that ED clinicians may identify patients at greatest risk of MRPs.

Abstract: To assess the association of postoperative delirium developed in the post‐anaesthetic care unit (PACU) with older patients' ability to perform activities of daily living (ADL) during the first five postoperative days. Previous studies have focused on the association between postoperative delirium and long‐term function decline, however the association between postoperative delirium and the ability to perform ADL, particularly in the immediate postoperative period, needs further investigation. A prospective cohort study. A total of 271 older patients who underwent elective or emergency surgery at a tertiary care hospital in Victoria, Australia, participated in the study. Data were collected between July 2021 and December 2021. Delirium was assessed using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM‐5). The Katz Index of Independence in Activities of Daily Living (KATZ ADL) scale was used to measure ADL. ADL was assessed preoperatively and daily during the first five postoperative days. The STROBE checklist was used to report this study. Results showed that 44 (16.2%) patients developed new episode of delirium. Postoperative delirium was independently associated with decline in ADL (RR = 2.83, 95% CI = 2.71–2.97 p 0.001). Postoperative delirium was associated with a decline in ADL among older people during the first five postoperative days. Screening for delirium in the PACU is essential to identify delirium during the early stages of postoperative period and implement a timely comprehensive plan. Delirium assessment of older patients in the PACU, and for at least the first five postoperative days, is strongly recommended. We also recommend engagement of patients in a focused physical and cognitive daily activity plan, particularly for older patients undergoing major surgery. Patients and nurses helped in data collection at a tertiary care hospital.
