What do we know about postoperative delirium (POD)? Preliminary results of a national survey

Abstract

Background and Goal of Study POD is the most common postoperative morbidity in elderlies. Is highly under-diagnosed, mainly due to lack of awareness. The aim was to assess anaesthesiologistsu2019 perspectives and management of POD. Materials and Methods After IRB approval, an online questionnaire based on a survey(1) was sent to anaesthesiologists working in Portugal and asked to anonymously participate. It was divided in 3 sections: demographics; questions regarding knowledge, subjective preferences and practices; and management of clinical cases. Answers were presented as a Likert scale from 1-5 (disagree completely to agree completely), or as yes/no/donu2019t know. Descriptive statistical analysis was conducted to report results. Results and Discussion Response rate was around 15%(193); 66% female, 29% residents, 87% from teaching hospitals. Detailed results are shown in Table 1. If the anaesthesiologists were to be submitted to a general anaesthesia, most would be concerned about neurocognitive side effects (4- 29%, 5- 28%) and 75% would want the depth of anaesthesia to be monitored. Majority states the risk for neurocognitive side effects should be considered when choosing type of anaesthesia (4-34%, 5-53%) and pre-operative neurocognitive function should be routinely assessed (4-44%, 5-33%). Considered major risk factors were: age, major surgery, alcoholism and previous stroke. Almost 96% of respondents have processed-EEG monitors in their hospitals and 50% always uses them. In fact, about 70% of anaesthesiologists believe that depth of anaesthesia should be monitored in all patients. Almost 60% recalled an episode of POD in the last year. When managing a case of an agitated and confused patient, 64% would first administer an analgesic and only 10% an anxiolytic (40% would choose a benzodiazepine). Most hospitals donu2019t have protocols to evaluate POD in PACU (56%) or surgical wards (61%). Around 97% of respondents believe that POD is a neglected field in anaesthesiology. Limitations: low response rate, sampling and recall bias. Conclusions Overall, anaesthesiologists are aware of the importance, risk factors and management for POD. Intraoperative monitoring of anaesthesia depth is recommended to lower the incidence of POD; although it is widely used there is space for improvement. Protocols for preoperative cognition evaluation and POD diagnosis and treatment should be sought. References(1) Ann Med Surg 2014 (3):100-7
