Long-term associations between cholinesterase inhibitors and memantine use and health outcomes among patients with Alzheimer's disease.

OBJECTIVES: To examine in an observational study (1) relationships between cholinesterase inhibitors (ChEI) and memantine use, and functional and cognitive end points and mortality in patients with Alzheimer's disease (AD); (2) relationships between other patient characteristics and these clinical end points; and (3) whether effects of the predictors change across time. METHODS: The authors conducted a multicenter, natural history study that included three university-based AD centers in the United States. A total of 201 patients diagnosed with probable AD with modified Mini-Mental State Examination (MMSE) scores ≥ 30 at study entry were monitored annually for 6 years. Discrete-time hazard analyses were used to examine relationships between ChEI and memantine use during the previous 6 months reported at each assessment, and time to cognitive (MMSE score ≤ 10) and functional (Blessed Dementia Rating Scale score ≥ 10) end points and mortality. Analyses controlled for clinical characteristics, including baseline cognition, function, and comorbid conditions, and presence of extrapyramidal signs and psychiatric symptoms at each assessment interval. Demographic characteristics included baseline age, sex, education, and living arrangement at each assessment interval. RESULTS: ChEI use was associated with delayed time in reaching the functional end point and death. Memantine use was associated with delayed time to death. Different patient characteristics were associated with different clinical end points. CONCLUSIONS: Results suggest long-term beneficial effects of ChEI and memantine use on patient outcomes. As for all observational cohort studies, observed relationships should not be interpreted as causal effects.

Pharmacist- versus physician-initiated admission medication reconciliation: impact on adverse drug events.

BACKGROUND: Medication reconciliation (MR) has proven to be a problematic task for many hospitals to accomplish. It is important to know the clinical impact of physician- versus pharmacist-initiated MR in the resource-limited hospital environment. METHODS: This quasi-experimental study took place from December 2005 to February 2006 at an urban US Veterans Affairs hospital. MR was implemented on 2 similar general medical units: one received physician-initiated MR and the other received pharmacist-initiated MR. Adverse drug events (ADEs) and a 72-hour medication-prescribing risk score were ascertained by research pharmacists for all admitted patients by structured record review. Multivariable models were tested for intervention effect, accounting for quasi-experimental design and clustered observations, and were adjusted for patient and encounter covariates. RESULTS: Pharmacists completed the MR process in 102 admissions and physicians completed the process in 116 admissions. In completing the MR process, pharmacists documented statistically more admission medication changes than physicians (3.6 vs 0.8; P < 0.001). The adjusted odds of an ADE caused by an admission prescribing change with pharmacist-initiated MR compared with a physician-initiated MR were 1.04 with a 95% CI of 0.53 to 2.0. The adjusted odds of an ADE caused by an admission prescribing change that was a prescribing error with pharmacist-initiated MR compared with a physician-initiated MR were 0.38 with a confidence interval of 0.14 to 1.05. No difference was observed in 72-hour prescribing risk score (coefficient = 0.10; 95% CI, -0.54 to 0.75). CONCLUSION: MR performed by pharmacists versus physicians was more comprehensive and was followed by lower odds of ADEs from admission prescribing errors but with similar odds of all types of ADEs. Further research is warranted to examine how MR tasks may be optimally divided among clinicians and the mechanisms by which MR affects the likelihood of subsequent ADEs.

Health care workforce development in rural america: when geriatrics expertise is 100 miles away.

The Geriatric Scholar Program (GSP) is a Department of Veterans Affairs' (VA) workforce development program to infuse geriatrics competencies in primary care. This multimodal educational program is targeted to primary care providers and ancillary staff who work in VA's rural clinics. GSP consists of didactic education and training in geriatrics and gerontology and in quality improvement (QI) and support to implement a local QI project; in addition, elective options include webinars, audio conferences, clinical practica, and mentoring. The program is effective in improving core competencies in geriatrics and in improving clinical care for older Veterans who receive health care in rural clinics.

Meeting standards of high-quality intensive care unit palliative care: clinical performance and predictors.

OBJECTIVES: High-quality care for intensive care unit patients and families includes palliative care. To promote performance improvement, the Agency for Healthcare Research and Quality's National Quality Measures Clearinghouse identified nine evidence-based processes of intensive care unit palliative care (Care and Communication Bundle) that are measured through review of medical record documentation. We conducted this study to examine how frequently the Care and Communication Bundle processes were performed in diverse intensive care units and to understand patient factors that are associated with such performance. DESIGN: Prospective, multisite, observational study of performance of key intensive care unit palliative care processes. SETTINGS: A surgical intensive care unit and a medical intensive care unit in two different large academic health centers and a medical-surgical intensive care unit in a medium-sized community hospital. PATIENTS: Consecutive adult patients with length of intensive care unit stay ≥5 days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Between November 2007 and December 2009, we measured performance by specified day after intensive care unit admission on nine care process measures: Identify medical decision-maker, advance directive and resuscitation preference, distribute family information leaflet, assess and manage pain, offer social work and spiritual support, and conduct interdisciplinary family meeting. Multivariable regression analysis was used to determine predictors of performance of five care processes. We enrolled 518 (94.9%) patients and 336 (83.6%) family members. Performances on pain assessment and management measures were high. In contrast, interdisciplinary family meetings were documented for <20% of patients by intensive care unit day 5. Performance on other measures ranged from 8% to 43%, with substantial variation across and within sites. Chronic comorbidity burden and site were the most consistent predictors of care process performance. CONCLUSIONS: Across three intensive care units in this study, performance of key palliative care processes (other than pain assessment and management) was inconsistent and infrequent. Available resources and strategies should be utilized for performance improvement in this area of high importance to patients, families, and providers.

Training nurses for interdisciplinary communication with families in the intensive care unit: an intervention.

BACKGROUND: Critical care nurse communication training has largely been limited to didactic materials, interactive training for nurse supervisors, or brief participatory learning programs within the context of comprehensive end-of-life care educational seminars. Preliminary evidence suggests that an interactive approach can also be effective in communication skills training for intensive care unit (ICU) nurses. METHODS: We implemented a 1-day educational intervention in five acute care hospitals within Veterans Integrated Service Network (VISN) 3 (New York-New Jersey region) of the Department of Veterans Affairs and focused solely on communication skills and targeted specifically to nurses providing bedside care for critically ill patients. A "learner centered" approach to skills training that has several integral components was employed. AMONG THESE ARE: a cognitive, evidence-based foundation upon which to build new skills; a method such as role-play that allows participants to practice newly learned skills; and an affective component, during which trainees can freely discuss their impressions of the exercise or explore difficulties that may have been encountered. Before and after the program we conducted a detailed assessment of participants' self-rated communication skills and of the techniques and materials we used. RESULTS AND CONCLUSIONS: Post-program responses documented significant improvement in self-evaluated skills for each of the core tasks we assessed. Evidence suggests that communication with patients and families in the ICU can be most effectively approached in an interdisciplinary way. For nurses to fully realize their potential for optimal communication as members of the multidisciplinary team, they must be equipped with the necessary skills. We believe this new program helps to expand the range of approaches for training nurses in essential communication skills.

Implementation and evaluation of a network-based pilot program to improve palliative care in the intensive care unit.

BACKGROUND: Intensive care unit (ICU) care could be improved by implementation of time-triggered evidence-based interventions including identification of a patient/family medical decision maker, the patient's advance directive status, and cardiopulmonary resuscitation preferences by Day 1; offer of social work and spiritual support by Day 3; and a family meeting establishing goals of care by Day 5. We implemented a program to improve care for ICU patients in five Department of Veterans Affairs' ICUs. MEASURES: We measured the percent of ICU patients with lengths of stay of five or more days that received the care processes by the appropriate day. INTERVENTION: Critical care and palliative care providers trained ICU nurse teams to improve care through auditing, performance feedback, improvement tools, education, and monthly team meetings. OUTCOMES: Pre- and postintervention care were compared. Offering social work and spiritual support, identification of the medical decision maker, and documentation of family meetings significantly improved. CONCLUSIONS/LESSONS LEARNED: ICU nurse teams can be engaged to improve care under the aegis of a collaborative quality improvement project.

Utilization of antihypertensives, antidepressants, antipsychotics, and hormones in Alzheimer disease.

This study explores the longitudinal relationship between patient characteristics and use of 4 drug classes (antihypertensives, antidepressants, antipsychotics, and hormones) that showed significant changes in use rates over time in patients with Alzheimer disease. Patient/caregiver-reported prescription medication usage was categorized by drug class for 201 patients from the Predictors Study. Patient characteristics included use of cholinesterase inhibitors and/or memantine, function, cognition, living situation, baseline age, and sex. Assessment interval, year of study entry, and site were controlled for. Before adjusting for covariates, useage increased for antihypertensives (47.8% to 62.2%), antipsychotics (3.5% to 27.0%), and antidepressants (32.3% to 40.5%); use of hormones decreased (19.4% to 5.4%). After controlling for patient characteristics, effects of time on the use of antidepressants were no longer significant. Antihypertensive use was associated with poorer functioning, concurrent use of memantine, and older age. Antipsychotic use was associated with poorer functioning and poorer cognition. Antidepressant use was associated with younger age, poorer functioning, and concurrent use of cholinesterase inhibitors and memantine. Hormone use was associated with being female and younger age. Findings suggest accurate modeling of the Alzheimer disease treatment paradigm for certain subgroups of patients should include antihypertensives and antipsychotics in addition to cholinesterase inhibitors and memantine.

A random effects multinomial logit analysis of using Medicare and VA healthcare among veterans with dementia.

This study aimed to examine longitudinal patterns of VA-only use, dual VA and Medicare use, or Medicare-only use among veterans with dementia. Data on VA and Medicare use (1998-2001) were obtained from VA administrative datasets and Medicare claims for 2,137 male veterans with a formal diagnosis of Alzheimer's disease or vascular dementia enrolled in the National Longitudinal Caregiver Study. A random effects multinomial logit model accounting for unobserved individual heterogeneity was used to estimate the effects of patient and caregiver characteristics on use group over time. Compared to VA-only use, dual VA and Medicare use was associated with being white, married, higher education, having private insurance, Medicaid, low VA priority level, more functional limitations, and having lived in a nursing home or died in that year. Medicare-only use was associated with older age, being married, higher education, having private insurance, low VA priority level, living further from a VA Medical Center, having more comorbidities, functional limitations, and having lived in a nursing home or died. Veterans whose caregivers reported better health were more likely to be dual users, but those whose caregivers reported more comorbidities were more likely to use Medicare only. Different aspects of veterans' needs and caregiver characteristics have differential effect on where veterans seek care. Efforts to coordinate care between VA and Medicare providers are necessary to ensure patients receive high quality care.

Longitudinal medication usage in Alzheimer disease patients.

This study examined in detail patterns of cholinesterase inhibitors (ChEIs) and memantine use and explored the relationship between patient characteristics and such use. Patients with probable Alzheimer disease AD (n=201) were recruited from the Predictors Study in 3 academic AD centers and followed from early disease stages for up to 6 years. Random effects logistic regressions were used to examine effects of patient characteristics on ChEIs/memantine use over time. Independent variables included measures of function, cognition, comorbidities, the presence of extrapyramidal signs, psychotic symptoms, age, sex, and patient's living situation at each interval. Control variables included assessment interval, year of study entry, and site. During a 6-year study period, rate of ChEIs use decreased (80.6% to 73.0%) whereas memantine use increased (2.0% to 45.9%). Random effects logistic regression analyses showed that ChEI use was associated with better function, no psychotic symptoms, and younger age. Memantine use was associated with better function, poorer cognition, living at home, later assessment interval, and later year of study entry. Results suggest that high rate of ChEI use and increasing memantine use over time are consistent with current practice guidelines of initiation of ChEIs in mild-to-moderate AD patients and initiation of memantine in moderate-to-severe patients.
