To determine the diagnostic accuracy of state, minimally invasive clinical and physical signs (or sets of signs) to be used as screening tests for detecting impending or current water-loss dehydration, or both, in older people by systematically reviewing studies that have measured a reference standard and at least one index test in people aged 65 years and over. 1 Clinical and physical signs for identification of impending and current water-loss dehydration in older people (Protocol)

Objectives In the emergency department (ED), health care providers miss delirium approximately 75% of the time, because they do not routinely screen for this syndrome. The Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) is a brief (<1 minute) delirium assessment that may be feasible for use in the ED. The study objective was to determine its validity and reliability in older ED patients. Methods In this prospective observational cohort study, patients aged 65 years or older were enrolled at an academic, tertiary care ED from July 2009 to February 2012. Research assistants (RAs) and an emergency physician (EP) performed the CAM-ICU. The reference standard for delirium was a comprehensive (~30 minutes) psychiatrist assessment using the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. All assessments were blinded to each other and were conducted within 3 hours. Sensitivities, specificities, and likelihood ratios were calculated for both the EP and the RAs using the psychiatrist’s assessment as the reference standard. Kappa values between the EP and RAs were also calculated to measure reliability. Results Of 406 patients enrolled, 50 (12.3%) had delirium. The median age was 73.5 years old (interquartile range [IQR] = 69 to 80 years), 202 (49.8%) were female, and 57 (14.0%) were nonwhite. The CAM-ICU’s sensitivities were 72.0% (95% confidence interval [CI] = 58.3% to 82.5%) and 68.0% (95% CI = 54.2% to 79.2%) in the EP and RAs, respectively. The CAM-ICU’s specificity was 98.6% (95% CI = 96.8% to 99.4%) for both raters. The negative likelihood ratios (LR–) were 0.28 (95% CI = 0.18 to 0.44) and 0.32 (95% CI = 0.22 to 0.49) in the EP and RAs, respectively. The positive likelihood ratios (LR+) were 51.3 (95% CI = 21.1 to 124.5) and 48.4 (95% CI = 19.9 to 118.0), respectively. The kappa between the EP and RAs was 0.92 (95% CI = 0.85 to 0.98), indicating excellent interobserver reliability. Conclusions In older ED patients, the CAM-ICU is highly specific, and a positive test is nearly diagnostic for delirium when used by both RAs and EPs. However, the CAM-ICU’s sensitivity was modest, and a negative test decreased the likelihood of delirium by a small amount. The consequences of a false-negative CAM-ICU are unknown and deserve further study.

EQUiPPED is a multicomponent quality improvement initiative combining education, electronic clinical decision support, and individual provider feedback to influence prescribing and improve medication safety for older adults. The objective here was to evaluate the effectiveness and sustainability of EQUiPPED to reduce the use of potentially inappropriate medications (PIMs), as defined by the American Geriatrics Society 2012 Beers Criteria, prescribed to older Veterans at the time of emergency department (ED) discharge. This evaluation represents a pre- and post-intervention comparison of PIM prescriptions at 4 urban Veteran Affairs (VA) Medical Center EDs. Poisson regression was used to compare the number of PIMs prescribed to Veterans 65 years or older discharged from the ED for at least 6 months prior to the first EQUiPPED intervention at each site and for at least 12 months following the final EQUiPPED intervention. The implementation timeline varied by site depending on local resources. All 4 sites showed a significant and sustained reduction in use of PIMs. The proportion of PIMs at site one decreased from 11.9% (SD 1.8) pre-EQUiPPED to 5.1% (SD 1.4) post-EQUiPPED (P < .0001); site 2 from 8.2% (SD 0.8) pre to 4.5% (SD 1.0) post (P < .0001); site 3 from 8.9% (SD 1.9) pre to 6.1% (SD 1.7) post (P = .0007); and site 4 from 7.4% (SD 1.7) pre to 5.7% (SD 0.8) post (P = .04). These results suggest a multicomponent program to influence provider prescribing behavior leads to safer prescribing for older adults discharged from the ED and is sustainable across multiple VA ED sites.
