RESUMO

Delirium is a common disorder in hospitalized older adults and the defining characteristic is a disturbance of consciousness. Unfortunately, there are currently no testable measures of consciousness as pertains to its disruption in delirium. Not surprisingly rates of recognition of delirium suffer. Arguably, a greater understanding of the quantum of consciousness may improve delirium diagnosis through better diagnostic tools. Candidate dimensions of consciousness derived from fields of psychology, psychiatry, and philosophy are discussed and relevance to delirium explored. Based upon existing literature in the field of consciousness we identify the pre-reflective state, experiential awareness, and functional networks as candidate sites that may be affected in delirium. Opportunities for clinical instrument development and how these tools can be tested are discussed. We conclude that consciousness content may not hold to a unitary measurement, but facets of its integrity that are impacted in delirium are open to further exploration. Disorders in pre-reflective status, experiential awareness, and functional networks may represent the measurable "rabbit holes" of consciousness disturbance.

RESUMO

ABSTRACTIntroduction:It is well established that there is a high prescribing rate of psychotropic agents in residential aged care (RAC). The appropriateness of these medications has become controversial, given the limited data on efficacy and growing evidence of associated adverse outcomes. OBJECTIVE: To assess psychotropic prescribing in RAC including identification of potentially inappropriate prescriptions (PIPs) and common psychological and behavioral symptoms indicated for prescribing. These were viewed in context of dementia and different RAC facilities. METHODS: Electronic care plans of 779 RAC residents across 12 facilities were examined to elucidate psychotropic prescribing rates, PIPs, and indications for use. RESULTS: One in two residents (48.1%) were prescribed a psychotropic drug. The primary reasons for prescribing were depression (61.5%), anxiety (26.7%), sleep problems (25.4%), agitation (13.7%), psychosis (11.0%), and other behaviors (7.2%). Residents with dementia (56.6%) were more likely to be prescribed a drug for agitation and psychosis, and had a significantly increased prescription rate for antidepressants (OR = 1.50, 95% CI = 1.08-2.08, p = 0.01) and antipsychotics (OR = 1.88, 95% CI = 1.23-2.88, p < 0.01). Conversely, residents with dementia were less likely to receive medication to combat sleeping difficulties, with significantly lower benzodiazepine prescribing (OR = 0.63, 95% CI = 0.44-0.91, p = 0.01). Over half of all psychotropic prescriptions (54.0%) were potentially inappropriate based on the Beers Criteria. There was high variability of prescribing rates between homes. CONCLUSION: There is a high prescribing rate of potentially inappropriate medications. Residents with dementia are more likely to receive medication for agitation and psychosis, and are less likely to receive medication to combat sleeping difficulties.
