Recent Advances in Screening for Mild Cognitive Impairment and Alzheimer Disease.

In recent years, scientific understanding of the pathophysiology underlying Alzheimer disease (AD) has advanced substantially. Among the most transformative of discoveries is the existence of biomarkers, such as Aß42, which can manifest in the central nervous system decades before the onset of disease-associated dementia. By detecting these biological entities early, clinicians can close diagnostic delays and substantially improve outcomes for patients with AD. With prompt news of a diagnosis, patients can initiate long-term planning and devise goals for treatment while their cognition is relatively intact. To differentiate among different forms of dementia, neurologists and supporting clinicians should additionally capitalize on the availability of validated screening tools. Increasingly adopted, tests such as the Montreal Cognitive Assessment yield highly sensitive, specific findings that can improve the standard of care. These results, when paired with insights gleaned from patient histories and clinical examinations, can further inform treatment-decision making and help ensure that patients receive care tailored to their unique circumstances and needs.

The Differential Diagnosis and Treatment of Mild Cognitive Impairment and Alzheimer Disease.

Identifying patients at risk for developing mild cognitive impairment (MCI) and Alzheimer disease (AD) remains challenging in clinical practice, even as scientific understanding of dementia advances generally. That said, successfully navigating the associated differential diagnosis in AD is essential, as various causes of cognitive impairment require different treatment strategies. In recent years, the armamentarium in AD has expanded with regulatory approval of a disease-modifying therapy-aducanumab-and may be shifting away from symptomatic treatments such as cholinesterase inhibitors and memantine. Concurrently, the role of biomarkers in AD is increasing, and these entities may soon play a greater role in determining patient eligibility for prophylactic interventions and the likelihood of disease progression. As the standard of care progresses, clinicians should educate patients and their care providers on the implications of these advances and reinforce lifestyle changes that can delay or prevent the onset of disease in those at risk of AD. In doing so, care providers can deliver the best care possible.

Understanding Coding and Payment for Psychiatrists' Services: How We Got Here and Where We're Going.

Psychiatrists often have difficulty understanding how to document, code, and bill for their services in a way that expedites adequate payment and avoids billing problems or future issues. This is very understandable because many psychiatrists in small or solo practices do their own billing without any formal training in the vagaries of coding and reimbursement policies. For many years, the American Psychiatric Association (APA) has devoted substantial resources to guiding psychiatrists through this maze, with direct member assistance and resources publicly available at www.psychiatry.org. APA staff, councils, and committees have also been working for many years to improve coding and reimbursement for psychiatric services. Current and former members and staff of the APA Committee on RBRVS, Codes, and Reimbursement have authored this article to help psychiatrists gain a better understanding of the current coding and reimbursement structure for psychiatric services, including how it evolved and what the future holds.

Further validation of the Internet-based Dementia Risk Assessment.

Most approaches to the detection of presymptomatic or prodromal Alzheimer's disease require the costly collection and analysis of biological samples or neuroimaging measurements. The Dementia Risk Assessment (DRA) was developed to facilitate this detection by collecting self-report and proxy-report of dementia risk variables and episodic memory performance on a free Internet website. We now report two validation studies. In Study 1, 130 community-residing older adults seeking memory screening at senior health fairs were tested using the Mini-Cog, and were then observed while taking the DRA. They were compared to a demographically-matched subsample from our anonymous Internet sample. Participants seeking memory screening had more dementia risk factors and obtained lower scores on the DRA's recognition memory test (RMT) than their Internet controls. In addition, those who failed the Mini-Cog obtained much lower scores on the RMT than those who passed the Mini-Cog. In Study 2, 160 older adults seeking evaluation of cognitive difficulties took the DRA prior to diagnostic evaluations at outpatient dementia clinics. Patients who ultimately received the diagnosis of a dementia syndrome scored significantly lower on the RMT than those diagnosed with other conditions or deemed normal. Lower education, family history of dementia, presence of hypercholesterolemia and diabetes, and memory test score distinguished the dementia and no-dementia groups with around 82% accuracy. In addition, score on the RMT correlated highly with scores on other instruments widely used to detect cognitive decline. These findings support the concurrent validity of the DRA for detecting prevalent cognitive impairment. Prospective studies of cognitively normal persons who subsequently develop dementia will be necessary to establish its predictive validity.

Internet-based screening for dementia risk.

The Dementia Risk Assessment (DRA) is an online tool consisting of questions about known risk factors for dementia, a novel verbal memory test, and an informant report of cognitive decline. Its primary goal is to educate the public about dementia risk factors and encourage clinical evaluation where appropriate. In Study 1, more than 3,000 anonymous persons over age 50 completed the DRA about themselves; 1,000 people also completed proxy reports about another person. Advanced age, lower education, male sex, complaints of severe memory impairment, and histories of cerebrovascular disease, Parkinson's disease, and brain tumor all contributed significantly to poor memory performance. A high correlation was obtained between proxy-reported decline and actual memory test performance. In Study 2, 52 persons seeking first-time evaluation at dementia clinics completed the DRA prior to their visits. Their responses (and those of their proxy informants) were compared to the results of independent evaluation by geriatric neuropsychiatrists. The 30 patients found to meet criteria for probable Alzheimer's disease, vascular dementia, or frontotemporal dementia differed on the DRA from the 22 patients without dementia (most other neuropsychiatric conditions). Scoring below criterion on the DRA's memory test had moderately high predictive validity for clinically diagnosed dementia. Although additional studies of larger clinical samples are needed, the DRA holds promise for wide-scale screening for dementia risk.

Cardiovascular centers of excellence program: a system approach for improving the care and outcomes of cardiovascular patients at HCA hospitals.

BACKGROUND: A voluntary continuous quality improvement (CQI) effort, the cardiovascular Centers of Excellence (COE) program was implemented by HCA, Inc., to improve cardiovascular care in its hospital system. METHODS: The cardiovascular COE program targeted 165 hospitals that provide cardiovascular services in at least one major service area. Awards (unrestricted grants) provided hospitals with an incentive to participate. RESULTS: One hundred fifty-eight hospitals (95.8%) completed the entire 2005 cardiovascular COE program; five were identified as cardiovascular COE. The program developed three key CQI activities: (1) an ongoing Web-based survey to inventory, track, and verify evidence-based practices across all aspects of patient care, including clinical practices, leadership, communications, patient safety, and patient education; (2) quarterly benchmark reports tracking risk-adjusted outcomes and evidence-based practices; and (3) regularly scheduled educational programs presented by an interdisciplinary team in which lessons learned from an institution's successful, evidence-based, best-practice implementation were discussed. DISCUSSION: The COE program successfully encouraged facilities to proacrively investigate their evidence-based clinical standards and outcomes.

Pre-transplant level of soluble CD30 is associated with infection after heart transplantation.

BACKGROUND: One immunologic element of the immune system is the CD30 molecule which belongs to the TNF-R superfamily. CD30 can serve as a T-cell signal transducing molecule and is expressed by a subset of activated T lymphocytes, CD45RO(+) memory T cells. Augmentation of soluble CD30 during kidney transplant (Tx) rejection has been reported. Our study was to determine if the level of sCD30 prior to heart transplant (HTx) could categorize the patients (pts) into high or low immunologic risk for post-Tx outcome. METHODS: Pre-Tx sera from 100 consecutive HTx recipients were studied. sCD30 was detected by ELISA using the commercially available CD30 monoclonal antibody. Level of sCD30 was correlated with two-yr Tx outcome. RESULTS: Significant correlation was seen between the high level of sCD30 and lower incidence of infection. Four of the 35 pts with pre-Tx high level of sCD30 level (>90 U/mL) developed infection post-Tx. However, 31/65 pts who had a low level of sCD30 (<90 U/mL) developed infection post-transplantation (p < 0.0003). No remarkable differences were noted with the other clinical parameters, including mean hospitalization, 3A biopsy rejection or death. CONCLUSIONS: We report for the first time that the high level of sCD30 prior to the HTx may be associated with a higher immunologic ability of the pts and therefore, may have a protective effect in the development of infection post-Tx.
