The collaborative care management (CCM) model has been demonstrated to be significantly more effective compared to usual care (UC) in depression management although an initial increase in cost measures was seen. In this paper, cost measures as well as clinical response were analyzed on patients with available follow-up data at six months. Records of 219 patients with follow-up data in CCM group and 119 in UC group were reviewed. At six months, there was a statistically significant clinical response rate among patients in CCM compared to UC group ( P < 0.0001). Likewise, 65% in CCM group was “symptom-free” at 6 months vs. 31.9% in UC group ( P < 0.0001). Among the responders in both groups, there was no statistical difference in cost measures. However, cost measures were significantly higher among non-responders compared to responders within CCM. Between the two models, the non-responders in UC had lower cost measures than the non-responders under CCM.

The high prevalence of no-shows in residents’ primary care clinic acts as a barrier to continuity of care, results in loss of outpatient learning opportunities, and may result in more emergency department (ED) visits. The authors seek to identify if high rates of no-shows correlate with more ED visits. In a selected primary care internal medicine (PCIM) continuity clinic, 650 patients were randomly selected, with 325 patients each from the faculty and resident practices. The number of ED visits between January 1, 2006, and December 30, 2008, was recorded. Demographic characteristics of the population were obtained, and comparisons between the faculty and resident groups were performed using Student t test. Linear multiple regression analysis was performed to compare frequency of ED visits between the faculty and the resident groups, controlling for age, interpreter requirement, number of ED visits, proportion of no-shows, and insurance type. A P value <.05 was considered statistically significant. During 2006-2008, the average number of ED visits per patient in the faculty’s practice was 2.1 compared with 4.1 in the resident’s practice ( P < .001). A multiple linear regression model showed that patients who had more ED visits were likely to be younger ( P = .004), had shorter duration of care in the PCIM clinic ( P < .001), and had a higher proportion of no-shows to the PCIM clinic ( P < .001). There was no statistical difference between faculty and resident practice after adjusting for the above-mentioned variables. Shorter duration in the PCIM clinic and higher proportion of missed appointments were associated with more ED visits, but the use of interpreters and Medicaid insurance did not result in more ED visits. Future interventions are necessary to reduce the no-show rate in the clinic as this may result in a reduction of ED visits.

Many primary care physicians understand the challenges of taking care of patients with depression. Care management models for depression have been described as more effective than usual practice. The implementation of such a model requires a clinic manager to be able to predict how this new process might impact staffing and clinical demand. This study was designed to evaluate the initial impact of the implementation of a depression care manager (CM) model on the utilization of outpatient visits. The hypothesis is that the introduction of a CM model for depression in a primary care practice would be associated with an increased utilization of health care resources when compared to usual care (UC). There were 38 patients enrolled during the initial 2 months of implementation of the CM model. Using a retrospective medical record review, the CM population was compared to a similar group receiving UC (N = 49), and a significant increase in the percentage of patients who were seen for any reason in the CM population was found (65.8% vs. 36.7%, P = 0.01). The average CM patient had 1.24 outpatient visits for any reason vs. 0.69 for the UC group ( P = 0.01). When specifically focusing on outpatient visits for depression, the CM group averaged 0.95 visits per patient as compared to the UC patients having 0.55 visits per patient ( P = 0.04). This study suggests that the initial implementation of a CM model for treatment of depression will increase outpatient utilization. ( Population Health Management 2009;12:227–230)

Background and Purpose: Stroke is a well-known risk factor for vascular dementia. However, the association of transient ischemic attacks with cognitive impairment is less well-established. Methods: Records from Third National Health and Nutrition Examination Survey were abstracted for demographic and medical information for participants with an age !60 years who reported being free of stroke. Five self-reported symptoms (weakness, numbness, loss of vision, inability to speak, and severe dizziness) were used as surrogates representing transient ischemic attacks. Information on conventional risk factors for vascular dementia was also obtained. Multivariable logistic regression was used to examine risk factors for memory impairment. Results: 4617 participants were included with a sample-weighted prevalence of memory impairment of 6.6% (1417 participants). The final multivariable analysis revealed a significant association between transient weakness and memory impairment (odds ratio 1.52, 95% CI 1.11-2.07). The other 4 transient ischemic attacks symptoms were not significantly associated with memory impairment in the final model. Systolic blood pressure >140 was most strongly associated with prevalent memory impairment (odds ratio, 9.78, 95% CI 1.49-64.3). Other associated risk factors included non-white race, male gender, age, education ≤12 years, and history of any alcohol use. Conclusion: Among transient ischemic attacks symptoms, self-reported weakness in the face, arm, or leg was significantly associated with memory impairment. This study indicates that transient ischemic attacks symptoms are, even in the absence of stroke, associated with memory impairment. Aggressive risk factor modification in patients with TIA symptoms may be warranted to prevent potential future memory loss.
