Diagnostic accuracy of the Dutch version of the 4AT for delirium detection in a mixed patient population and setting.

BACKGROUND: Delirium is an acute disturbance in attention, awareness and cognition. Immediate detection in older adults is recommended because delirium is associated with adverse outcomes. The 4 'A's Test (4AT) is a short screening instrument for delirium. The aim of this study is to evaluate diagnostic accuracy of the Dutch version of the screening tool 4AT for delirium detection in different settings. METHODS: Prospective observational study conducted in two hospitals in patients aged ≥ 65 years in geriatric wards and the Emergency Department (ED). Each participant underwent two assessments; the index test 4AT, followed by the reference standard for delirium performed by a geriatric care specialist. The reference standard delirium is according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) criteria. RESULTS: A total of 71 geriatric inpatients and 49 older ED patients were included. The prevalence of delirium was 11.6% in the acute geriatric ward and 6.1% in the ED. The sensitivity and specificity of the 4AT in the acute geriatric ward were 0.88 and 0.69, respectively. In the ED, the sensitivity and specificity were 0.67 and 0.83, respectively. The area under the receiver operating characteristic curve was 0.80 for the acute geriatric ward setting and 0.74 for the ED setting. CONCLUSION: The Dutch version of the 4AT is a reliable screening tool for delirium detection in both acute geriatric wards and ED. Due to its brevity and practicality (i.e., no special training is required to administer the tool), it is useful in clinical practice.

Screening instruments for cognitive impairment in older patients in the Emergency Department: a systematic review and meta-analysis.

BACKGROUND: cognitive impairment is highly prevalent among older patients attending the Emergency Department (ED) and is associated with adverse outcomes. METHODS: we conducted a systematic review and meta-analysis to evaluate the diagnostic accuracy of cognitive screening instruments to rule out cognitive impairment in older patients in the ED. A comprehensive literature search was performed in MEDLINE, EMBASE, CINAHL and CENTRAL. A risk of bias assessment using QUADAS-2 was performed. RESULTS: 23 articles, examining 18 different index tests were included. Only seven index tests could be included in the meta-analysis. For ruling out cognitive impairment irrespective of aetiology, Ottawa 3 Day Year (O3DY) (pooled sensitivity 0.90; (95% CI) 0.71-0.97) had the highest sensitivity. Fourteen articles focused on screening for cognitive impairment specifically caused by delirium. For ruling out delirium, the 4 A's Test (4AT) showed highest sensitivity (pooled sensitivity 0.87, 95% confidence interval (95% CI) 0.74-0.94). CONCLUSIONS: high clinical and methodological heterogeneity was found between included studies. Therefore, it is a challenge to recommend one diagnostic test for use as a screening instrument for cognitive impairment in the ED. The 4AT and O3DY seem most promising for ruling out cognitive impairment in older patients attending the ED.The review protocol was registered in PROSPERO (CRD42018082509).

[Factors influencing professional decision making on acute hospital referral in the case of elderly patients with cognitive impairment among general practitioners (GPs) in The Netherlands: a qualitative study]. / Overwegingen van huisartsen bij het verwijzen van ouderen met een cognitieve stoornis naar het ziekenhuis: een kwalitatief onderzoek.

BACKGROUND: Elderly patients with cognitive impairment have a limited life expectancy and are often acutely admitted to the hospital. Hospitalization can negatively affect their quality of life. More knowledge on considerations prior to these referrals is needed to improve care for these patients. AIM: The aim of this research is to describe the aspects that can relate to the process of referring to the hospital in the acute situation by GPs in the case of elderly patients with cognitive impairment. METHOD: Semi-structured interviews with 21 GPs from The Netherlands were conducted and afterwards transcribed verbatim. From these transcripts categories were extracted by using 131 focused codes according to the grounded theory. RESULTS: Twelve categories were constructed. Six categories relate to whether it is desirable to treat or refer. These are the illness itself, the patient's wishes, the condition of the patient, the patient's burden, the possibilities in the hospital, and the vision of the GP. Six categories relate to the options available to the GP. These include medical options, care options, available time and information, the support available to the GP, and referrals without involvement of the GP. CONCLUSION: The referral of elderly patients with cognitive impairment is a complex process that is influenced by different types of factors. With these findings, specialists in hospitals, GPs, and policy makers can improve the quality of care for this group.

[Factors influencing the referral of nursing home patients to the hospital]. / Factoren die van invloed zijn op het verwijzen van patiënten van het verpleeghuis naar het ziekenhuis.

INTRODUCTION: Hospitalisation may cause negative effects on elderly patients. Therefore, it is important that referral and admission of older nursing home patients is well-considered. The aim of this study is to investigate the factors that affect the decision making process. METHOD: Questionnaire survey among elderly care physicians and physicians following the elderly care physician training program. RESULTS: Of the 1,540 surveys, 200 were returned (response rate of 13%). Over 60% of the respondents had referred a nursing home patient to the hospital in the previous month. A stay at a geriatric rehabilitation ward, suspicion of a fracture, a good quality of life, a patient's or family's wish for referral, no treatment restrictions, and follow-up appointments in the hospital were factors which made referral to the hospital more likely according to the respondents. Medical specialist consultation and the in hospital presence of a physician specialised in geriatric care were considered to be important. Referral was less likely if a patient was diagnosed with dementia, had a low quality of life or had treatment restrictions. CONCLUSION: Both patient-related and non-patient-related factors influence hospital referral of nursing home patients. Further research is needed to determine whether these different factors contribute to the different outcomes of a hospital admission, to facilitate proper decision-making for elderly care physicians.

Hospital at Home care for older patients with cognitive impairment: a protocol for a randomised controlled feasibility trial.

INTRODUCTION: An acute hospital admission is a stressful life event for older people, particularly for those with cognitive impairment. The hospitalisation is often complicated by hospital-associated geriatric syndromes, including delirium and functional loss, leading to functional decline and nursing home admission. Hospital at Home care aims to avoid hospitalisation-associated adverse outcomes in older patients with cognitive impairment by providing hospital care in the patient's own environment. METHODS AND ANALYSIS: This randomised, non-blinded feasibility trial aims to assess the feasibility of conducting a randomised controlled trial in terms of the recruitment, use and acceptability of Hospital at Home care for older patients with cognitive impairment. The quality of care will be evaluated and the advantages and disadvantages of the Hospital at Home care programme compared with usual hospital care. Eligible patients will be randomised either to Hospital at Home care in their own environment or usual hospital care. The intervention consists of hospital level care provided at patients' homes, including visits from healthcare professionals, diagnostics (laboratory tests, blood cultures) and treatment. The control group will receive usual hospital care. Measurements will be conducted at baseline, during admission, at discharge and at 3 and 6 months after the baseline assessment. ETHICS AND DISSEMINATION: Institutional ethics approval has been granted. The findings will be disseminated through public lectures, professional and scientific conferences, as well as peer-reviewed journal articles. The study findings will contribute to knowledge on the implementation of Hospital at Home care for older patients with cognitive disorders. The results will be used to inform and support strategies to deliver eligible care to older patients with cognitive impairment. TRIAL REGISTRATION NUMBER: e020313; Pre-results.
