The postoperative delirium in older adults guideline project was initiated by selecting an interdisciplinary, multi-specialty 23 member panel. The panel was chosen by the American Geriatrics Society's Geriatrics-for-Specialists Initiative (AGS-GSI) council with additional input from the panel co-chairs, with the goal of selecting participants with special interest and expertise in postoperative delirium. Represented disciplines included the fields of geriatric medicine, general surgery, anesthesiology, emergency medicine, geriatric surgery, gynecology, hospital medicine, critical care medicine, neurology, neurosurgery, nursing, obstetrics and gynecology, orthopedic surgery, ophthalmology, otolaryngology, palliative care, pharmacy, psychiatry, physical medicine and rehabilitation, thoracic surgery, urology, and vascular surgery.Additional ex officio panel members included a representative from the National Committee for Quality Assurance (NCQA), a quality measures expert, and a caregiver representative. The following panel members served on the writing group for this best practices statement: Stacie Deiner, MD;Conflicts of interest were disclosed initially and updated three times during guideline development. Disclosures were reviewed by the entire panel and potential conflicts resolved by the co-chairs (see Appendix 1).
LITERATURE REVIEWThe methods for postoperative delirium risk factors, screening (case finding), and diagnosis (Table 1, Topics I to III) were distinct from the other aims, because these topics were thoroughly addressed in recent high-quality guideline statements and systematic reviews upon which the recommendation statements in these sections were based. 4,20-22 Additionally, these topics were considered outside the scope of the main literature search, which focused on prevention and treatment of delirium in the perioperative setting. Key citations were included in the section summaries. Sections were drafted by panel groups and then refined with the committee co-chairs. Subsequently, full consensus of the panel was achieved for all recommendation statements and summary sections.The methods for the literature search for the aims addressing the pharmacologic and nonpharmacologic interventions for the prevention or treatment of postoperative delirium in older adults (Table 1, Topics IV to X) included comprehensive searches, targeted searches, and focused searches. A more detailed description of the search methods is found in the accompanying clinical guideline document. 19 Comprehensive searches (1988( to December 2013 in PubMed, Embase, and CINAHL used the search terms delirium, organic brain syndrome, and acute confusion and resulted in a total of 6,504 articles. Additional, alternative terms included for the prevention and treatment of delirium were the words prevention, management, treatment, intervention, therapy, therapeutic, and drug therapy.
