Delirium's Arousal Subtypes and Their Relationship with 6-Month Functional Status and Cognition.

OBJECTIVE: We sought to determine how delirium subtyped by arousal affected 6-month function and cognition in acutely ill older patients. METHODS: This was secondary analysis of a prospective cohort study which enrolled hospitalized patients ≥65 years old. Delirium and arousal were ascertained daily in the emergency department and the first 7 days of hospitalization using the modified Brief Confusion Assessment Method and Richmond Agitation Sedation Scale, respectively. For each day, patients were categorized as having no delirium, delirium with normal arousal, delirium with decreased arousal, or delirium with increased arousal. Preillness and 6-month functional status were determined using the Older American Resources and Services activities of daily living scale which ranges from 0 (completely dependent) to 28 (completely independent). Preillness and 6-month cognition were determined using the Informant Questionnaire on Cognitive Decline in the Elderly which ranges from 1 (markedly improved cognition) to 5 (severe cognitive impairment). Multiple linear regression was performed adjusted for preillness Older American Resources and Services activities of daily living and Informant Questionnaire on Cognitive Decline in the Elderly and other relevant confounders. RESULTS: In 228 older patients, delirium with normal arousal was the only subtype independently associated with poorer 6-month function and cognition. For every day spent in this subtype, the 6-month Older American Resources and Services activities of daily living decreased by 0.84 points (95% confidence interval: -1.59 to -0.09) and the patient's 6-month Informant Questionnaire on Cognitive Decline in the Elderly significantly increased by 0.14 points (95% confidence interval: 0.06-0.23). CONCLUSIONS: Delirium with normal arousal, as opposed to delirium with decreased or increased arousal, was the only arousal subtype significantly associated with worsening 6-month function and cognition. Subtyping delirium by arousal may have important prognostic value.

A patient-centered deprescribing intervention for hospitalized older patients with polypharmacy: rationale and design of the Shed-MEDS randomized controlled trial.

BACKGROUND: Polypharmacy is prevalent among hospitalized older adults, particularly those being discharged to a post-care care facility (PAC). The aim of this randomized controlled trial is to determine if a patient-centered deprescribing intervention initiated in the hospital and continued in the PAC setting reduces the total number of medications among older patients. METHODS: The Shed-MEDS study is a 5-year, randomized controlled clinical intervention trial comparing a patient-centered describing intervention with usual care among older (≥50 years) hospitalized patients discharged to PAC, either a skilled nursing facility (SNF) or an inpatient rehabilitation facility (IPR). Patient measurements occur at hospital enrollment, hospital discharge, within 7 days of PAC discharge, and at 60 and 90 days following PAC discharge. Patients are randomized in a permuted block fashion, with block sizes of two to four. The overall effectiveness of the intervention will be evaluated using total medication count as the primary outcome measure. We estimate that 576 patients will enroll in the study. Following attrition due to death or loss to follow-up, 420 patients will contribute measurements at 90 days, which provides 90% power to detect a 30% versus 25% reduction in total medications with an alpha error of 0.05. Secondary outcomes include the number of medications associated with geriatric syndromes, drug burden index, medication adherence, the prevalence and severity of geriatric syndromes and functional health status. DISCUSSION: The Shed-MEDS trial aims to test the hypothesis that a patient-centered deprescribing intervention initiated in the hospital and continuing through the PAC stay will reduce the total number of medications 90 days following PAC discharge and result in improvements in geriatric syndromes and functional health status. The results of this trial will quantify the health outcomes associated with reducing medications for hospitalized older adults with polypharmacy who are discharged to post-acute care facilities. TRIAL REGISTRATION: This trial was prospectively registered at clinicaltrials.gov ( NCT02979353 ). The trial was first registered on 12/1/2016, with an update on 09/28/17 and 10/12/2018.

Health literacy, cognition, and urinary incontinence among geriatric inpatients discharged to skilled nursing facilities.

AIMS: To investigate the association between health literacy and cognition and nursing and patient-reported incontinence in a geriatric inpatient population transitioning to skilled nursing facilities (SNF). METHODS: Health literacy, depression, and cognition were assessed via the Brief Health Literacy Screen (BHLS), Geriatric Depression Scale 5-item (GDS) and Brief Interview for Mental Status (BIMS), respectively. Multivariable logistic regression assessed the association between BHLS score and incontinence by: (1) nursing-reported urinary incontinence during hospitalization; and (2) patient self-reported "bladder accidents" in the post-enrollment study interview. RESULTS: A total of 1556 hospitalized patients aged 65 and older met inclusion criteria, of whom 922 (59.3%) were women and 1480 had available BHLS scores. A total of 464 (29.8%) and 515 (33.1%) patients had nursing-reported and self-reported urinary incontinence, respectively. Nursing-reported incontinence was significantly associated with lower BHLS (ie, poorer health literacy) (aOR 0.93, 95%CI 0.89-0.99) and BIMS (ie, poorer cognition) (aOR 0.90, 95%CI 0.83-0.97) scores and need for assistance with toileting (aOR 7.08, 95%CI 2.16-23.21). Patient-reported incontinence was significantly associated with female sex (aOR 1.62, 95%CI 1.19-2.21), increased GDS score (ie, greater likelihood of depression) (aOR 1.22, 95%CI 1.10-1.36) and need for assistance with toileting (aOR 2.46, 95%CI 1.26-4.79). CONCLUSIONS: Poorer health literacy and cognition are independently associated with an increased likelihood of nursing-reported urinary incontinence among geriatric inpatients transitioning to SNF. Practitioners should consider assessment of health literacy and cognition in frail patients at risk for urinary incontinence and that patient and nursing assessment may be required to capture the diagnosis.

An evaluation of single question delirium screening tools in older emergency department patients.

OBJECTIVES: To determine the diagnostic performances of several single question delirium screens. To the patient we asked: "Have you had any difficulty thinking clearly lately?" To the patient's surrogate, we asked: "Is the patient at his or her baseline mental status?" and "Have you noticed the patient's mental status fluctuate throughout the course of the day?" METHODS: This was a prospective observational study that enrolled English speaking patients 65 years or older. A research assistant (RA) and emergency physician (EP) independently asked the patient and surrogate the single question delirium screens. The reference standard for delirium was a consultation-liaison psychiatrist's assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria. All assessments were performed within 3 h and were all blinded to each other. RESULTS: Of the 406 patients enrolled, 50 (12%) were delirious. A patient who was unable to answer the question "Have you had any difficulty thinking clearly lately?" was 99.7% (95% CI: 98.0%-99.9%) specific, but only 24.0% (95% CI: 14.3%-37.4%) sensitive for delirium when asked by the RA. The baseline mental status surrogate question was 77.1% (95% CI: 61.0%-87.9%) sensitive and 87.5% (95% CI: 82.8%-91.1%) specific for delirium when asked by the RA. The fluctuating course surrogate question was 77.1% (95% CI: 61.0%-87.9%) sensitive and 80.2% (95% CI: 74.8%-84.7%) specific. When asked by the EP, the single question delirium screens' diagnostic performances were similar. CONCLUSIONS: The patient and surrogate single question delirium assessments may be useful for delirium screening in the ED.

Exploring Delirium's Heterogeneity: Association Between Arousal Subtypes at Initial Presentation and 6-Month Mortality in Older Emergency Department Patients.

OBJECTIVES: To determine how delirium subtyped by level of arousal at initial presentation affects 6-month mortality. DESIGN: This was a preplanned secondary analysis of two prospective cohort studies. SETTING: Academic tertiary care emergency department (ED). PARTICIPANTS: 1,084 ED patients who were 65 years old or older. MEASUREMENTS: At the time of enrollment, trained research personnel performed the Confusion Assessment Method for the Intensive Care Unit and the Richmond Agitation Sedation Score to determine delirium and level of arousal, respectively. Patients were categorized as having no delirium, delirium with normal arousal, delirium with decreased arousal, or delirium with increased arousal. Death was ascertained by medical record review and the Social Security Death Index. Cox proportional hazard regression was used to analyze the association between delirium arousal subtypes and 6-month mortality. RESULTS: Delirium with normal arousal was the only subtype that was significantly associated with increased 6-month mortality (hazard ratio [HR]: 3.1, 95% confidence interval [CI]: 1.3-7.4) compared with the no delirium group after adjusting for confounders. The HRs for delirium with decreased and increased arousal were 1.4 (95% CI: 0.9-2.1) and 1.3 (95% CI: 0.3-5.4), respectively. CONCLUSIONS: Delirious ED patients with normal arousal at initial presentation had a threefold increased hazard of death within 6 months compared with patients without delirium. There was a trend towards increased hazard of death in delirious ED patients with decreased arousal, but this relationship did not reach statistical significance. These data suggest that subtyping delirium by arousal may have prognostic value but requires confirmation with a larger study.

A quick and easy delirium assessment for nonphysician research personnel.

OBJECTIVES: Delirium in the emergency department (ED) is an emerging field of research. Most ED research infrastructures utilize lay personnel to collect data, but delirium assessments that can be reliably performed by nonphysicians are lacking. We evaluated the diagnostic performance of the modified Brief Confusion Assessment Method (modified bCAM) for this purpose. METHODS: This was a secondary analysis of a prospective observational study that enrolled ED patients 65years or older. The original bCAM was a brief (<2minutes) delirium assessment that assessed for inattention by asking the patient to recite the months backward from December to July. It was modified by adding the Vigilance A ("squeeze my hand when you hear the letter 'A'") to the inattention assessment. The elements of the modified bCAM were performed by a research assistant (RA) and emergency physician. The reference standard for delirium was a psychiatrist assessment performed within 3hours using Diagnostic and Statistical Manual of Mental Disorder, Fourth Edition, Text Revision criteria. All assessors were blinded to each other. Sensitivities and specificities with their 95% confidence intervals (CIs) were calculated for the RA and emergency physician. RESULTS: Of the 406 patients enrolled, 50 (12%) were delirious. The modified bCAM was 82.0% (95% CI, 71.4%-92.6%) sensitive and 96.1% (95% CI, 94.0%-98.1%) specific when performed by the RA. The emergency physician's modified bCAM exhibited similar diagnostic performance. CONCLUSIONS: The modified bCAM may be a feasible and accurate method for nonphysicians to assess for delirium. Future studies are needed to confirm these findings.

Effect of Health Literacy on Research Follow-Up.

Previous research has not examined the effect of health literacy on research subjects' completion of scheduled research follow-up. This article evaluates patient factors associated with incomplete research follow-up at three time points after enrollment in a large, hospital-based prospective cohort study. Predictor variables included health literacy, age, race, gender, education, employment status, difficulty paying bills, hospital diagnosis, length of stay, self-reported global health status, depression, perceived health competence, medication adherence, and health care system distrust. In a sample of 2,042 patients, multivariable models demonstrated that lower health literacy and younger age were significantly associated with a lower likelihood of completing research follow-up interviews at 2-3 days, 30 days, and 90 days after hospital discharge. In addition, patients who had less education, were currently employed, and had moderate financial stress were less likely to complete 90-day follow-up. This study is the first to demonstrate that lower health literacy is a significant predictor of incomplete research follow-up.

Determinants of health after hospital discharge: rationale and design of the Vanderbilt Inpatient Cohort Study (VICS).

BACKGROUND: The period following hospital discharge is a vulnerable time for patients when errors and poorly coordinated care are common. Suboptimal care transitions for patients admitted with cardiovascular conditions can contribute to readmission and other adverse health outcomes. Little research has examined the role of health literacy and other social determinants of health in predicting post-discharge outcomes. METHODS: The Vanderbilt Inpatient Cohort Study (VICS), funded by the National Institutes of Health, is a prospective longitudinal study of 3,000 patients hospitalized with acute coronary syndromes or acute decompensated heart failure. Enrollment began in October 2011 and is planned through October 2015. During hospitalization, a set of validated demographic, cognitive, psychological, social, behavioral, and functional measures are administered, and health status and comorbidities are assessed. Patients are interviewed by phone during the first week after discharge to assess the quality of hospital discharge, communication, and initial medication management. At approximately 30 and 90 days post-discharge, interviewers collect additional data on medication adherence, social support, functional status, quality of life, and health care utilization. Mortality will be determined with up to 3.5 years follow-up. Statistical models will examine hypothesized relationships of health literacy and other social determinants on medication management, functional status, quality of life, utilization, and mortality. In this paper, we describe recruitment, eligibility, follow-up, data collection, and analysis plans for VICS, as well as characteristics of the accruing patient cohort. DISCUSSION: This research will enhance understanding of how health literacy and other patient factors affect the quality of care transitions and outcomes after hospitalization. Findings will help inform the design of interventions to improve care transitions and post-discharge outcomes.

Implementing toileting trials in nursing homes: evaluation of a dissemination strategy.

OBJECTIVES: This study sought to improve incontinence care in nursing homes (NHs) by administering and evaluating a webinar course that provided extended instruction to help NHs implement toileting trials in accordance with recommended procedures. Of particular interest was: 1) whether the course design would prompt NH staffs to implement the recommended protocol, and 2) whether participants preferred this course design to other models. DESIGN: The study collected descriptive evaluation data. SETTING: The setting was comprised of seven NHs. PARTICIPANTS: Participants were staff members, typically nurses, from enrolled NHs who attended at least three of the six webinars that comprised the course. MEASURES: Data was collected using a course evaluation and implementation survey. RESULTS: Staff in the participating nursing homes attended an average of 4.85 webinars, with an average of nine staff members attending each webinar (range: 3-20). Twelve of 16 responding participants said they preferred the webinar course to other course designs. All respondents said they would recommend the course and take a similar course again. All facilities submitted some evidence that staff providers had completed implementation assignments. Most facilities reported plans to sustain use of the recommended protocol. CONCLUSION: This study found limited evidence that the webinar course prompts NHs to implement a recommended toileting trial protocol and is preferred to other training program designs.

Diagnosing delirium in older emergency department patients: validity and reliability of the delirium triage screen and the brief confusion assessment method.

STUDY OBJECTIVE: Delirium is a common form of acute brain dysfunction with prognostic significance. Health care professionals caring for older emergency department (ED) patients miss delirium in approximately 75% of cases. This error results from a lack of available measures that can be performed rapidly enough to be incorporated into clinical practice. Therefore, we developed and evaluated a novel 2-step approach to delirium surveillance for the ED. METHODS: This prospective observational study was conducted at an academic ED in patients aged 65 years or older. A research assistant and physician performed the Delirium Triage Screen (DTS), designed to be a highly sensitive rule-out test, and the Brief Confusion Assessment Method (bCAM), designed to be a highly specific rule-in test for delirium. The reference standard for delirium was a comprehensive psychiatrist assessment using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. All assessments were independently conducted within 3 hours of one another. Sensitivities, specificities, and likelihood ratios with their 95% confidence intervals (95% CIs) were calculated. RESULTS: Of 406 enrolled patients, 50 (12.3%) had delirium diagnosed by the psychiatrist reference standard. The DTS was 98.0% sensitive (95% CI 89.5% to 99.5%), with an expected specificity of approximately 55% for both raters. The DTS's negative likelihood ratio was 0.04 (95% CI 0.01 to 0.25) for both raters. As the complement, the bCAM had a specificity of 95.8% (95% CI 93.2% to 97.4%) and 96.9% (95% CI 94.6% to 98.3%) and a sensitivity of 84.0% (95% CI 71.5% to 91.7%) and 78.0% (95% CI 64.8% to 87.2%) when performed by the physician and research assistant, respectively. The positive likelihood ratios for the bCAM were 19.9 (95% CI 12.0 to 33.2) and 25.2 (95% CI 13.9 to 46.0), respectively. If the research assistant DTS was followed by the physician bCAM, the sensitivity of this combination was 84.0% (95% CI 71.5% to 91.7%) and specificity was 95.8% (95% CI 93.2% to 97.4%). If the research assistant performed both the DTS and bCAM, this combination was 78.0% sensitive (95% CI 64.8% to 87.2%) and 97.2% specific (95% CI 94.9% to 98.5%). If the physician performed both the DTS and bCAM, this combination was 82.0% sensitive (95% CI 69.2% to 90.2%) and 95.8% specific (95% CI 93.2% to 97.4%). CONCLUSION: In older ED patients, this 2-step approach (highly sensitive DTS followed by highly specific bCAM) may enable health care professionals, regardless of clinical background, to efficiently screen for delirium. Larger, multicenter trials are needed to confirm these findings and to determine the effect of these assessments on delirium recognition in the ED.

Quality assurance and performance improvement in nursing homes: using evidence-based protocols to observe nursing care processes in real time.

The Quality Assurance and Performance Improvement Initiative, a component of the Affordable Care Act (2010), is a new approach to quality improvement for US nursing homes. The article describes components of the Quality Assurance and Performance Improvement Initiative, the unique contributions of registered nurses to its implementation, and data collection strategies using direct observation and evidence-based measures and protocols in a Quality Assurance and Performance Improvement program.

Effect of physical and occupational therapy on delirium duration in older emergency department patients who are hospitalized.

Objective: Delirium in older emergency department (ED) adults is associated with poorer long-term physical function and cognition. We sought to evaluate if the time to and intensity of physical and/or occupational therapy (PT/OT) are associated with the duration of ED delirium into hospitalization (ED delirium duration). Methods: This is a secondary analysis of a prospective cohort study conducted from March 2012 to November 2014 at an urban, academic, tertiary care hospital. Patients aged ≥65 years presenting to the ED and who received PT/OT during their hospitalization were included. Days from enrollment to the first PT/OT session and PT/OT duration relative to hospital length of stay (PT/OT intensity) were abstracted from the medical record. ED delirium duration was defined as the duration of delirium detected in the ED using the Brief Confusion Assessment Method. Data were analyzed using a proportional odds logistic regression adjusted for multiple variables. Adjusted odds ratios (ORs) were calculated with 95% confidence intervals (95%CI). Results: The median log PT/OT intensity was 0.5% (interquartile range [IQR]: 0.3%, 0.9%) and was associated with shorter delirium duration (adjusted OR, 0.39; 95% CI, 0.21-0.73). The median time to the first PT/OT session was 2 days (IQR: 1, 3 days) and was not associated with delirium duration (adjusted OR, 1.02; 95% CI, 0.82-1.27). Conclusion: In older hospitalized adults, higher PT/OT intensity may be a useful intervention to shorten delirium duration. Time to first PT/OT session was not associated with delirium duration but was initiated a full 2 days after the ED presentation.

The effect of cognitive impairment on the accuracy of the presenting complaint and discharge instruction comprehension in older emergency department patients.

STUDY OBJECTIVE: We seek to determine how delirium and dementia affect the accuracy of the presenting illness and discharge instruction comprehension in older emergency department (ED) patients. METHODS: This cross-sectional study was conducted at an academic ED from May 2008 to July 2008 and included non-nursing home patients aged 65 years and older. Two open-ended interviews were performed to assess patients' ability to accurately provide their presenting illness and comprehension of their ED discharge instructions. The surrogates' version of the presenting illness and printed discharge instructions were the reference standards. Concordance between the patient and the reference standards was determined by 2 reviewers using a 5-point scale ranging from 1 (no concordance) to 5 (complete concordance). Proportional odds logistic regression was performed to determine whether cognitive impairment was associated with presenting complaint accuracy and discharge instruction comprehension. All models were adjusted for age, health literacy, education, nonwhite race, and hearing impairment. RESULTS: For the presenting illness analysis, 202 patients participated. Compared with patients without cognitive impairment, those with delirium superimposed on dementia (DSD) had lower odds of agreeing with their surrogates with regard to why they were in the ED (adjusted proportional odds ratio=0.20; 95% confidence interval [CI] 0.09 to 0.43). For the discharge instruction comprehension analysis, 115 patients participated. Patients with DSD had significantly lower odds of comprehending their discharge diagnosis (adjusted proportional odds ratio=0.13; 95% CI 0.04 to 0.47), return to the ED instructions (adjusted proportional odds ratio=0.18; 95% CI 0.04 to 0.82), and follow-up instructions (adjusted proportional odds ratio=0.09; 95% CI 0.02 to 0.35) compared with patients without cognitive impairment. CONCLUSION: DSD is associated with decreased accuracy of the older patient's presenting illness and decreased comprehension of ED discharge instructions.

Disparities in Research Participation by Level of Health Literacy.

OBJECTIVE: To determine at which phase in the recruitment process for participation in clinical research studies do health literacy and other patient characteristics influence recruitment outcomes. PATIENTS AND METHODS: Using a sample of 5872 patients hospitalized with cardiovascular disease approached for participation in the Vanderbilt Inpatient Cohort Study from October 2011 through December 2015, we examined the independent association of patients' health literacy with two steps in their research participation decision-making process: (1) research interest - willingness to hear more about a research study; and (2) research participation - the decision to enroll after an informed consent discussion. Best practices for effective health communication were implemented in recruitment approaches and informed consent processes. Using logistic regression models, we determined patient characteristics independently associated with patients' willingness to hear about and participate in the study. RESULTS: In unadjusted analyses, participants with higher health literacy, and those who were younger, female, or had more education had higher levels of both research interest and research participation. Health literacy remained independently associated with both outcomes in multivariable models, after adjustment for sociodemographic factors. CONCLUSION: Because identical variables predicted both research interest and eventual consent, efforts to recruit broad populations must include acceptable methods of approaching potential participants as well as explaining study materials.

Delirium in the emergency department: an independent predictor of death within 6 months.

STUDY OBJECTIVE: Delirium's adverse effect on long-term mortality in older hospitalized patients is well documented, whereas its effect in older emergency department (ED) patients remains unclear. Similarly, the consequences of delirium on nursing home patients treated in the ED are also unknown. As a result, we seek to determine whether delirium in the ED is independently associated with 6-month mortality in older patients and whether this relationship is modified by nursing home status. METHODS: Our prospective cohort study was conducted at a tertiary care, academic ED, using convenience sampling, and included English-speaking patients who were aged 65 years and older and were in the ED for less than 12 hours at enrollment. Patients were excluded if they refused consent, were previously enrolled, were unable to follow simple commands at baseline, were comatose, or had incomplete data. The Confusion Assessment Method for the Intensive Care Unit was used to determine delirium and was administered by trained research assistants. Cox proportional hazard regression was performed to determine whether delirium in the ED was independently associated with 6-month mortality after adjusting for age, comorbidity burden, severity of illness, dementia, functional dependence, and nursing home residence. To test whether the effect of delirium in the ED on 6-month mortality was modified by nursing home residence, an interaction term (delirium*nursing home) was incorporated into the multivariable model. Hazard ratios with their 95% confidence intervals were reported. RESULTS: Of the 628 patients enrolled, 108 (17.2%) were delirious in the ED and 58 (9.2%) were from the nursing home. For the entire cohort, the 6-month mortality rate was higher in the delirious group compared with the nondelirious group (37.0% versus 14.3%). Delirium was an independent predictor of increased 6-month mortality (hazard ratio=1.72; 95% confidence interval 1.04 to 2.86) after adjusting for age, comorbidity burden, severity of illness, dementia, functional dependence, and nursing home residence. The "delirium*nursing home" interaction was nonsignificant (P=.86), indicating that place of residence had no effect on the relationship between delirium in the ED and 6-month mortality. CONCLUSION: Delirium in older ED patients is an independent predictor of increased 6-month mortality, and this relationship appears to be present regardless of nursing home status.

Medication Discrepancies in Older Veterans Receiving Home Healthcare.

In a prospective cohort study of Veterans and community health nurses, we enrolled hospitalized older Veterans referred to home care for skilled nursing and/or physical or occupational therapy for posthospitalization care. We assessed preadmission activities of daily living and instrumental activities of daily living, health literacy, numeracy, and cognition. Postdischarge phone calls identified medication errors and medication reconciliation efforts by home healthcare clinicians. Veterans Administration-based community health nurses completed surveys about content and timing of postdischarge interactions with home healthcare clinicians. We determined the types and frequency of medication errors among older Veterans receiving home healthcare, patient-provider communication patterns in this setting, and patient characteristics affecting medication error rates. Most Veterans (24/30, 80%) had at least one discordant medication, and only one noted that errors were identified and resolved. Veterans were asked about medications in the home healthcare setting, but far fewer were questioned about medication-taking details, adherence, and as-needed or nonoral medications. Higher numeracy was associated with fewer errors. Veterans Administration community health nurses reported contact by home healthcare clinicians in 41% of cases (7/17). Given the high rate of medication errors discovered, future work should focus on implementing best practices for medication review in this setting, as well as documenting barriers/facilitators of patient-provider communication.

Prevalence of Spasticity in Nursing Home Residents.

OBJECTIVES: To determine the prevalence, rate of underdiagnosis and undertreatment, and association with activities of daily living dependency of spasticity in a nursing home setting. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: This study is an analysis of a deidentified data set generated by a prior quality improvement project at a 240-bed nursing home for residents receiving long-term care or skilled nursing care services. METHODS: Each resident was examined by a movement disorders specialist neurologist to determine whether spasticity was present and, if so, the total number of spastic postures present in upper and lower limbs was recorded. Medical records, including the Minimum Data Set, were reviewed for neurologic diagnoses associated with spasticity, activities of daily living (ADL) dependency, and prior documentation of diagnosis and past or current treatments. Ordinary least squares linear regression models were used to evaluate the association between spasticity and ADL dependency. RESULTS: Two hundred nine residents (154 women, 81.9 ± 10.9 years) were included in this analysis. Spasticity was present in 22% (45/209) of residents examined by the neurologist. Only 11% of residents (5/45) had a prior diagnosis of spasticity and were receiving treatment. Presence of spasticity was associated with greater ADL dependency (χ2 = 51.72, P < .001), which was driven by lower limb spasticity (χ2 = 14.56, P = .006). CONCLUSIONS AND IMPLICATIONS: These results suggest that spasticity (1) is common in nursing homes (1 of 5 residents), (2) is often not diagnosed or adequately treated, and (3) is associated with worse ADL dependency. Further research is needed to enhance the rates of diagnosis and treatment of spasticity in long-term care facilities.

Improving Care Transitions for Hospitalized Veterans Discharged to Skilled Nursing Facilities: A Focus on Polypharmacy and Geriatric Syndromes.

Geriatric syndromes and polypharmacy are common in older patients discharged to skilled nursing facilities (SNFs) and increase 30-day readmission risk. In a U.S.A. Department of Veterans Affairs (VA)-funded Quality Improvement study to improve care transitions from the VA hospital to area SNFs, Veterans (N = 134) were assessed for geriatric syndromes using standardized instruments as well as polypharmacy, defined as five or more medications. Warm handoffs were used to facilitate the transfer of this information. This paper describes the prevalence of geriatric syndromes, polypharmacy, and readmission rates. Veterans were prescribed an average of 14.7 medications at hospital discharge. Moreover, 75% of Veterans had more than two geriatric syndromes, some of which began during hospitalization. While this effort did not reduce 30-day readmissions, the high prevalence of geriatric syndromes and polypharmacy suggests that future efforts targeting these issues may be necessary to reduce readmissions among Veterans discharged to SNF.

Supratherapeutic Psychotropic Drug Levels in the Emergency Department and Their Association with Delirium Duration: A Preliminary Study.

OBJECTIVES: Polypharmacy is associated with delirium, but the mechanisms for this connection are unclear. Our goal was to determine the frequency of supratherapeutic psychotropic drug levels (SPDLs) in older hospitalized patients and if it is associated with the duration of emergency department (ED) delirium. DESIGN: Secondary analysis of a prospective cohort study. SETTING: Tertiary care academic medical center. PARTICIPANTS: ED patients 65 years or older who were admitted to the hospital. MEASUREMENTS: Delirium was assessed in the ED and during the first 7 days of hospitalization using the modified Brief Confusion Assessment Method. Drug concentrations were determined in serum samples collected at enrollment via a novel platform based on liquid chromatography-tandem mass spectrometry capable of identifying and quantitating 78 clinically approved medications including opioids, benzodiazepines, antidepressants, antipsychotics, and amphetamines. Patients with serum psychotropic drug concentrations above established reference ranges were considered supratherapeutic and have a SPDL. We performed proportional odds logistic regression to determine if SPDLs were associated with ED delirium duration adjusted for confounders. Medical record review was performed to determine if the doses of medications associated with SPDLs were adjusted at hospital discharge. RESULTS: A total of 158 patients were enrolled; of these, 66 were delirious in the ED. SPDLs were present in 11 (17%) of the delirious and 4 (4%) of the non-delirious ED patients. SPDLs were significantly associated with longer ED delirium duration (adjusted proportional odds ratio = 6.0; 95% confidence interval = 2.1-17.3) after adjusting for confounders. Of the 15 medications associated with SPDLs, 9 (60%) were prescribed at the same or higher doses at the time of hospital discharge. CONCLUSION: SPDLs significantly increased the odds of prolonged ED delirium episodes. Approximately half of the medications associated with SPDLs were continued after hospital discharge at the same or higher doses. J Am Geriatr Soc 67:2387-2392, 2019.

The nursing home culture-change movement: recent past, present, and future directions for research.

This article uses a retrospective approach to critique the research base underlying the nursing home culture-change movement-an effort to radically transform the nation's nursing homes by delivering resident-directed care and empowering staff. The article traces the development of the movement from its inception 10 years ago to 2005, when the Centers for Medicare and Medicaid Services implemented its own initiative to support the movement, thus giving it new momentum, to the present day. This historical overview provides context for a proposed research agenda aimed at strengthening the movement's empirical base, thereby facilitating culture-change interventions as well as helping the movement navigate the next step in its evolution.
