In the subgroup with moderate-severe dementia (n=108), the sensitivity and the specificity were 79% and 82%, respectively, with a PPV and NPV of 62% and 92%. In the subgroup with severe dementia (n=26) the sensitivity was 82% and the specificity 56% with a PPV of 78% and a NPV of 63%. The availability of a specific tool to detect delirium in patients with moderate-severe dementia has important clinical and research implications, allowing all health care providers to improve their ability to identify it.

The intent of this study was to determine the diagnostic accuracy of several diagnostic tests for age-related macular degeneration (AMD), diabetic retinopathy (DR), glaucoma, and cataract, as well as the proportions of patients with eye disease from each of 3 enrolling clinics. Diagnostic accuracy study. Patients ≥50 years old in a diabetes, thyroid, and general medicine clinic were screened using visual acuity, tonometry, and fundus photography. Photographs were graded at the point-of-screening by non-ophthalmic personnel. Participants with positive screening test results in either eye and a 10% random sample with negative results in both eyes were referred for an in-person, reference-standard ophthalmology examination. Of 889 participants enrolled, 229 participants failed at least 1 test in either eye, of which 189 presented for an ophthalmic examination. An additional 76 participants with completely normal screening test results were referred for examination, of which 50 attended. Fundus photography screening had the highest yield f
