Each patient was asked to complete the Self-Report Version of the HABC Monitor and the Telephone Interview for Cognitive Status (TICS) over the telephone.
Patients meeting the following criteria were eligible for the study: 1) age ≥65 years, 2) had at least one visit to primary care during the period from January 1, 2008 to April 1, 2011, and 3) had any International Classification of Diseases, Ninth Revision (ICD-9) code (using both inpatient and outpatient Regenstrief Medical Record Systems over the 3 years 2005–2008) indicating cognitive impairment or had received at least one prescription of a cholinesterase inhibitor or memantine or had any ICD-9 code indicating depression or had received at least one prescription of a selective serotonin reuptake inhibitor.
Subject recruitment and testing During a quality improvement project to evaluate the implementation of the collaborative care model for patients suffering from cognitive or emotional problems, we contacted a random sample of patients meeting the inclusion criteria at two time points – prior to the implementation of the collaborative care model (2009) and 1 year after the implementation of such a model (2010).
Total score was a sum of all 27 items in the three symptom domains.
Higher scores represent worse scores for individual symptom domains and for the overall scale.
