Ultrabrief Screens for Detecting Delirium in Postoperative Cognitively Intact Older Adults

Validation of a viable delirium detection test performed by nurses and physicians during routine patient care

BACKGROUND

Delirium is a frequent mental impairment in geriatric patients hospitalized in acute care facilities. It carries a high risk of complications and is often the first symptom of acute illness. It is clearly important to identify the development of delirium at an early stage, and several short and effective diagnostic tests have been developed and validated for this purpose. Despite this, patients on hospital wards are seldom monitored for signs of emergent delirium, suggesting that compliance with guidelines would be improved by introducing a simpler and more user-friendly test.

METHODS

We recently implemented a simple delirium assessment tool, called RMA that can be introduced into the daily routine of ward staff without significantly adding to their workload. The nurses noted their impression of the patient's cognitive state in the electronic medical record, and during the morning round the ward physician administered a short attention test to any patients suspected of new cognitive impairment. In this study, we compared RMA test against the widely used and well validated 4AT.

RESULTS

RMA performed daily by the ward staff was found to be non-inferior to 4AT performed by an experienced rater. Compared to 4AT, R&M had a sensitivity of 93.9% and a specificity of 98.3%. An Altman-Bland plot indicated that both tests can be used interchangeably.

CONCLUSIONS

The RMA test is reliable, easy to administer, likely to boost compliance with guidelines, and is expected to raise awareness of delirium among the nurses and physicians directly involved in the diagnostic process.

Engaging Older Adults and Families Using the IDEAL Discharge Protocol: A Quality Improvement Initiative to Improve Outcomes and Reduce Readmissions

Older adults have challenges understanding newly prescribed medications after discharge and must be more adherent with medications and follow up with their primary care provider. A collaborative discharge process is critical to improving patient outcomes and reducing avoidable readmission rates. This quality improvement (QI) initiative engaged 44 patients and families in the IDEAL Discharge Protocol-an evidence-based collaborative care process focused on discussion, education, and post-discharge follow up. Post-discharge follow up resulted in the completion of 52.2% of follow-up calls and 45.5% of follow-up appointments scheduled, and a 4% reduction in readmission rates. Medication adherence was assessed and found to be 93.3%, and 100% of participants received education while engaged in the study. The IDEAL Discharge Protocol aided in improving the discharge process to better equip patients with the tools to transition home successfully after discharge.

Current Trends for Delirium Screening within the Emergency Department

Delirium is an acute neurological disorder that involves attention and cognition. It is associated with a high risk of morbidity and mortality among older people (>65 years old). In the context of the Emergency Department (ED), it is frequently experienced by patients but often not recognized. Literature studies have identified some screening instruments for an initial evaluation of delirium. Most of these tools have not been validated yet in the context of emergencies, but, in other settings, they were very useful for assessing and maximizing the recognition of this condition among older patients. We conducted a review of the literature, including randomized control trials, clinical and observational studies, and research studies published in recent years, confirming that most of the screening tools for delirium used in the intensive care unit (ICU) or the geriatric department have not been tested in the ED, and the ideal timing and form of the delirium assessment process for older adults have not been defined yet. The aim of our review is to summarize the updated evidence about the screening tools for delirium in the context of the ED, due to the fact that overcrowding of the ED and the stressful condition of emergency situations (that contribute to the onset of delirium) could expose older patients to a high risk of complications and mortality if delirium is not promptly recognized. In conclusion, we support the evidence that delirium is a current and real condition that emergency physicians have to face daily, and we are aware that more research is needed to explore this field in order to improve the overall outcomes of older patients admitted to the ED.
