Abstract:
Purpose: The purpose of our research is to examine the presence of delirium in hospitalized older adults and adverse events associated with unrecognized delirium. Theoretical Framework: Our research on delirium is based upon the idea of optimal system stability as discussed within the Neuman Systems Model. Delirium often is missed in hospitalized older adults over the age of 70. Research suggests that the prevalence of delirium in this population is between 10 ? 40% upon hospital admission while the incidence of new delirium during hospitalization ranges from between 6 - 56% and 25 - 60%. Screening instruments such as the Confusion Assessment Method (CAM) demonstrate significant accuracy in identifying patients with delirium and may be used by nurses and physicians to decrease the occurrence of adverse events associated with delirium. These events include dehydration, infection, malnutrition, physical restraint, poly-pharmacy, and even death. Methods (Design, Sample, Setting, Measures, Analysis): A retrospective chart review is conducted using randomly selected medical records of older adult patients hospitalized at any time between July - December 2002 (pre-intervention phase) as compared to July - December 2006 (post-intervention phase). Interventions include the introduction of the Geriatric Resource Nurse (GRN) program in 2003, the development of the Geriatric Consult Service in 2003, and educational trainings about delirium as offered to nurses, physicians, and mid-level providers. Results: Preliminary statistical analyses from the pre-intervention phase suggest that 15 - 40% of the sample (n = 181) experienced delirium during hospitalization and that delirium frequently remained unrecognized by clinical staff. Significant percentages of older adults experienced delirium in conjunction with immobilization and/or poly-pharmacy involving medications such as acetaminophen and benzodiazepines. Conclusions and Implications: Results from the post-intervention phase will inform the researchers about the effectiveness of the aforementioned interventions in reducing adverse events associated with the presence of delirium.
