Diagnosis, prevention, and management of delirium in the intensive cardiac care unit.

Delirium is a frequent complication in patients admitted to intensive cardiac care units (ICCU) with potentially severe consequences including increased risks of mortality, cognitive impairment and dependence at discharge, and longer times on mechanical ventilation and hospital stay. Delirium has been widely documented and studied in general intensive care units and in patients after cardiac surgery, but it has barely been studied in acute nonsurgical cardiac patients. Moreover, delirium (especially in its hypoactive form) is commonly misdiagnosed. We propose a protocol for delirium prevention and management in ICCUs. A daily comprehensive assessment to improve detection should be done using validated scales (ie, confusion assessment method). Preventive measures are particularly relevance and constitute the basis of treatment as well, acting on reversible risk factors, including environmental interventions, such as quiet time, sleep promotion, family support, communication, and adequate treatment of pain and dyspnea. Pharmacological prophylaxis is not indicated with the exception of patients at risk of withdrawal syndrome but should only be used in patients with confirmed delirium. Dexmedetomidine is the drug of choice in patients with severe agitation, and those weaning from invasive mechanical ventilation. As the complexity of ICCUs increases, clinical scenarios posing challenges for the management of delirium become more frequent. Efforts should be done to improve the identification of patients at risk during admission in order to establish preventive interventions to avoid this complication. Patient-centered protocols will increase the awareness of the healthcare professionals for better prevention and earlier diagnosis and will positively impact on prognosis.

Effect of Barthel Index on the Risk of Thirty-Day Mortality in Patients With Acute Heart Failure Attending the Emergency Department: A Cohort Study of Nine Thousand Ninety-Eight Patients From the Epidemiology of Acute Heart Failure in Emergency Departments Registry.

STUDY OBJECTIVE: We assess the value of the Barthel Index (BI) in predicting 30-day mortality risk among patients with acute heart failure who are attending the emergency department (ED). METHODS: We selected 9,098 acute heart failure patients from the Acute Heart Failure in Emergency Departments registry who had BI score available both at baseline and the ED visit. Patients' data were collected from 41 Spanish hospitals during four 1- to 2-month periods between 2009 and 2016. Unadjusted and adjusted logistic regression models were used to assess the association between 30-day mortality and BI score. c Statistics were used to estimate their prognostic value. RESULTS: The mean baseline BI score was 79.4 (SD 24.6) and the mean ED BI score was 65.3 (SD 29.1). Acute functional decline (≥5-point decrease between baseline BI and ED BI score) was observed in 5,771 patients (53.4%). Within 30 days of the ED visit, 905 patients (9.9%) died. There was a steep inverse gradient in 30-day mortality risk for baseline BI and ED BI score. For instance, compared with BI score=100, a BI score of 50 to 55 doubled the mortality risk both at baseline and the ED visit. At the ED visit, a BI score of 0 to 5 carried a 5-fold increase in risk after adjustment for other risk predictors. In comparison with baseline BI score, ED BI score consistently provided greater discrimination. Neither baseline BI score nor the change in BI score from baseline to the ED visit added further prognostic value to the ED BI score. CONCLUSION: Functional status assessed by the BI score at the ED visit is a strong predictor of 30-day mortality in acute heart failure patients, with higher predictive value than baseline BI score and acute functional decline. Routine recording of BI score at the ED visit may help in decisionmaking and health care planning.

Statin Treatment and Prognosis of Elderly Patients Discharged after Non-ST Segment Elevation Acute Coronary Syndrome.

BACKGROUND: Statins are recommended for secondary prevention. Our aims were to describe the proportion of very elderly patients receiving statins after non-ST segment elevation acute coronary syndrome (NST-ACS) and to determine the prognostic implications of statins use. METHODS: This prospective registry was performed in 44 hospitals that included patients ≥80 years discharged after a NST-ACS from April 2016 to September 2016. RESULTS: We included 523 patients, the mean age was 84.2 ± 4.0 years and 200 patients (38.2%) were women. Previous statin treatment was recorded in 282 patients (53.4%), and 135 (32.5%) had LDL cholesterol levels >2.6 mmol/L. Mean LDL cholesterol levels during admission were 2.3 ± 0.9 mmol/L. Statins were prescribed at discharge to 474 patients (90.6%). Compared with patients discharged on statins, those that did not receive statins were more often frail (22 [47.8%] vs. 114 [24.4%], p < 0.01) and underwent an invasive approach less frequently (30 [61.2%] vs. 374 [78.9%], p = 0.01). During a 6-month follow-up, 50 patients died (9.5%). There was a nonsignificant trend to higher mortality in patients not treated with statins (6 [15%] vs. 44 [9.6%], p = 0.30), but statins were not independently associated with lower mortality (hazard ratio [HR] 0.79; 95% confidence interval [CI] 0.30-2.11, p = 0.65), nor with a reduction in the combined endpoint mortality/hospitalizations (HR 0.89; 95% CI 0.52-1.55, p = 0.69). CONCLUSIONS: Although most octogenarians presenting a NST-ACS are already on statins before the episode, their LDL cholesterol is frequently >2.6 mmol/L. Octogenarians who do not receive statins have a high-risk profile, with significant frailty and comorbidity.

Diabetes mellitus, frailty and prognosis in very elderly patients with acute coronary syndromes.

BACKGROUND: The magnitude of the association between diabetes (DM) and outcomes in elderly patients with acute coronary syndromes (ACS) is controversial. No study assessed the prognostic impact of DM according to frailty status in these patients. METHODS: The LONGEVO-SCA registry included unselected ACS patients aged ≥ 80 years. Frailty was assessed by the FRAIL scale. We evaluated the impact of previous known DM on the incidence of death or readmission at 6 months according to status frailty by the Cox regression method. RESULTS: A total of 532 patients were included. Mean age was 84.3 years, and 212 patients (39.8%) had previous DM diagnosis. Patients with DM had more comorbidities and higher prevalence of frailty (33% vs 21.9%, p = 0.002). The incidence of death or readmission at 6 months was higher in patients with DM (HR 1.52, 95% CI 1.12-2.05, p 0.007), but after adjusting for potential confounders this association was not significant. The association between DM and outcomes was not significant in robust patients, but it was especially significant in patients with frailty [HR 1.72 (1.05-2.81), p = 0.030, p value for interaction = 0.049]. CONCLUSIONS: About 40% of elderly patients with ACS had previous known DM diagnosis. The association between DM and outcomes was different according to frailty status.

Incidence and impact of delirium on clinical and functional outcomes in older patients hospitalized for acute cardiac diseases.

BACKGROUND: Delirium is one of the most frequent complications of hospitalization in elderly patients. Its influence on prognosis in patients admitted for acute cardiac diseases is not well known. The objective of this study is to assess the incidence of delirium and its impact on clinical and functional outcomes in older patients hospitalized for acute cardiac diseases. METHODS: We prospectively analyzed 203 patients aged 75years or older admitted to a cardiology unit. Delirium was diagnosed with the Confusion Assessment Method. Logistic regression analysis was used to assess independent predictors of in-hospital delirium and to examine the independent risk of mortality, readmission, functional decline, and need for new help at discharge, at 1month and 12months associated with the development of delirium, after adjusting for age, comorbidity, and initial diagnosis. RESULTS: The incidence of delirium was 17.2%. Patients with delirium were older (83±5 vs 81±5years, P=.016) and showed a higher prevalence of major geriatric syndromes (82.9% vs 54.5%, P=.002). Aggressive ventilation modes, urinary catheters, prolonged fluid therapy, night treatments, longer immobilization, and physical restrain were associated with the incidence of delirium. Patients with delirium presented longer stays (8.9±6.2 vs 6.5±4.0days, P=.016) and a greater adjusted risk of functional decline at discharge (odds ratio 2.94, 95% CI 1.10-7.86, P=.032) and of 12-month mortality (odds ratio 4.20, 95% CI 1.81-9.74, P=.001). CONCLUSION: Delirium is a common preventable complication in older patients with acute cardiac diseases. It is associated with poorer in-hospital functional and clinical outcomes, and increased postdischarge mortality.

Effects of reminiscence therapy on anxiety and depression during acute hospitalization in older patients: Controlled study.

BACKGROUND/OBJECTIVES: Hospitalization due to acute illness in older patients is often associated with anxiety or depressive symptoms. In these circumstances, given that pharmacologic treatment should be avoided to reduce interactions with ongoing medication regimes, psychotherapy techniques should be considered. The purpose of this study was to evaluate the effectiveness of group reminiscence therapy (RT) on the reduction of anxiety and depressive symptoms in acutely hospitalized older patients. METHODS: Controlled and prospective study conducted on the Acute Geriatric Unit of a university hospital. Patients included in the intervention group (RT Group) attended a group session focused on RT, whereas those included in the control group (UC) received usual hospital care. Exclusion criteria were severe cognitive impairment, impossibility to mobilize, and clinical/hemodynamic instability. The intervention was based on a multi-task daily group session of reminiscence activities. The severity of anxiety (Hamilton Anxiety Rating Scale, HAM-A), depressive symptoms (15-item Geriatric Depression Scale, GDS-15), loneliness (ESTE-II social loneliness scale), and fear of death (Collet-Lester scale) was assessed at admission and discharge in both groups. RESULTS: The intervention was effective in reducing the proportion of patients with anxiety and depressive symptoms during hospitalization. The proportion of patients with moderate-severe anxiety at discharge was 32.1% in the UC and 13.4% in the RT Group (p < 0.001), whereas the proportion of patients with depressive symptoms at discharge was 49.1% in the UC and 19.5% in the RT Group (p < 0.001). The intervention was independently associated with benefits on anxiety levels (RR 2.45, 95% CI 1.83-3.28) and depression (RR 3.71, 95% CI 2.22-6.19) at discharge. No differences were found in loneliness or fear of death. CONCLUSIONS: A group reminiscence activity reduces the proportion of patients with anxiety and depressive symptoms during hospitalization for an acute disease. Absolute changes in both anxiety and depression scores, even though significant, were relatively small.

Causes and effects of surgical delay in patients with hip fracture: a cohort study.

BACKGROUND: The clinical effect of surgical delay in older patients with hip fracture is controversial. Discrepancies among study findings may be due to confounding that is caused by the reason for the delay or a differential effect on patient risk subgroups. OBJECTIVE: To assess the effect of surgical delay on hospital outcomes according to the cause of delay. DESIGN: Prospective cohort study. SETTING: A hip fracture unit in a university hospital in Spain. PATIENTS: 2250 consecutive elderly patients with hip fracture. MEASUREMENTS: Time to surgery, reasons for surgical delay, adjusted in-hospital death, and risk for complications. RESULTS: Median time to surgery was 72 hours. Lack of operating room availability (60.7%) and acute medical problems (33.1%) were the main reasons for delays longer than 48 hours. Overall, rates of hospital death and complications were 4.35% and 45.9%, respectively, but were 13.7% and 74.2% in clinically unstable patients. Longer delays were associated with higher mortality rates and rates of medical complications. After adjustment for age, dementia, chronic comorbid conditions, and functionality, this association did not persist for delays of 120 hours or less but did persist for delays longer than 120 hours (P = 0.002 for overall time effect on death and 0.002 for complications). The risks were attenuated after adjustment for the presence of acute medical conditions as the cause of the delay (P = 0.06 for time effect on mortality and 0.31 on medical complications). Risk for urinary tract infection remained elevated (odds ratio, 1.54 [95% CI, 0.99 to 2.44]). No interaction between delay and age, dementia, or functional status was found. LIMITATION: This was a single-center study without postdischarge follow-up. CONCLUSION: The reported association between late surgery and higher morbidity and mortality in patients with hip fracture is mostly explained by medical reasons for surgical delay, although some association between very delayed surgery and worse outcomes persists. PRIMARY FUNDING SOURCE: None.

Functional trajectories associated with acute illness and hospitalization in oldest old patients: Impact on mortality.

Background: The literature pays low attention to functional changes during acute illness in older patients. Our main objectives were to separately describe the different functional changes occurring before and after hospital admission in oldest old medical patients, to investigate their association with mortality, and identify predictors associated with in-hospital failure to recover function. Methods: Secondary analysis of data from a prospective cohort study conducted in a tertiary teaching hospital. The study followed the STROBE criteria. The sample included 604 consecutive patients aged 65 or older hospitalized for acute illness, discharged alive, and not fully dependent at baseline. Activities of daily living measured at baseline, admission, and discharge were used to classify patients into four functional trajectories depending on whether they decline or remain stable between baseline and admission (prehospital) and whether they decline, remain stable, or recover baseline function between admission and discharge (in-hospital). Multivariate models were used to test the association between functional trajectories with mortality, and predictors for in-hospital recovery. Results: Functional trajectories were: "stable-stable" (18%); "decline-recovery" (18%); "decline-no recovery" (53%); "in-hospital decline" (11%). Prehospital decline occurred in 75% and 64% were discharged with worse function than baseline. "In-hospital decline" and "decline-no recovery" trajectories were independently associated with higher 6- and 12-month mortality. Extent of prehospital decline and dementia were predictors of failure to in-hospital recovery. Conclusion: In acutely ill older people, differentiating between prehospital and in-hospital functional changes has prognostic implications. Lack of functional regain at discharge is associated with higher mortality at 6- and 12-months.

Prediction of 30-day mortality in older patients with a first acute myocardial infarction.

OBJECTIVES: This study sought predictors of mortality in patients aged >or=75 years with a first ST-segment elevation myocardial infarction (STEMI) and evaluated the validity of the GUSTO-I and TIMI risk models. METHODS: Clinical variables, treatment and mortality data from 433 consecutive patients were collected. Univariable and multivariable logistic regression analyses were applied to identify baseline factors associated with 30-day mortality. Subsequently a model predicting 30-day mortality was created and compared with the performance of the GUSTO-I and TIMI models. RESULTS: After adjustment, a higher Killip class was the most important predictor (OR 16.1; 95% CI 5.7-45.6). Elevated heart rate, longer time delay to admission, hyperglycemia and older age were also associated with increased risk. Patients with hypercholesterolemia had a significantly lower risk (OR 0.46; 95% CI 0.24-0.86). Discrimination (c-statistic 0.79, 95% CI 0.75-0.84) and calibration (Hosmer-Lemeshow 6, p = 0.5) of our model were good. The GUSTO-I and TIMI risk scores produced adequate discrimination within our dataset (c-statistic 0.76, 95% CI 0.71-0.81, and c-statistic 0.77, 95% CI 0.72-0.82, respectively), but calibration was not satisfactory (HL 21.8, p = 0.005 for GUSTO-I, and HL 20.6, p = 0.008 for TIMI). CONCLUSIONS: Short-term mortality in elderly patients with a first STEMI depends most importantly on initial clinical and hemodynamic status. The GUSTO-I and TIMI models are insufficiently adequate for providing an exact estimate of 30-day mortality risk.

Trends in length of stay and short-term outcomes among Medicare patients hospitalized for heart failure, 1993-2006.

CONTEXT: Whether decreases in the length of stay during the past decade for patients with heart failure (HF) may be associated with changes in outcomes is unknown. OBJECTIVE: To describe the temporal changes in length of stay, discharge disposition, and short-term outcomes among older patients hospitalized for HF. DESIGN, SETTING, AND PARTICIPANTS: An observational study of 6,955,461 Medicare fee-for-service hospitalizations for HF between 1993 and 2006, with a 30-day follow-up. MAIN OUTCOME MEASURES: Length of hospital stay, in-patient and 30-day mortality, and 30-day readmission rates. RESULTS: Between 1993 and 2006, mean length of stay decreased from 8.81 days (95% confidence interval [CI], 8.79-8.83 days) to 6.33 days (95% CI, 6.32-6.34 days). In-hospital mortality decreased from 8.5% (95% CI, 8.4%-8.6%) in 1993 to 4.3% (95% CI, 4.2%-4.4%) in 2006, whereas 30-day mortality decreased from 12.8% (95% CI, 12.8%-12.9%) to 10.7% (95% CI, 10.7%-10.8%). Discharges to home or under home care service decreased from 74.0% to 66.9% and discharges to skilled nursing facilities increased from 13.0% to 19.9%. Thirty-day readmission rates increased from 17.2% (95% CI, 17.1%-17.3%) to 20.1% (95% CI, 20.0%-20.2%; all P < .001). Consistent with the unadjusted analyses, the 2005-2006 risk-adjusted 30-day mortality risk ratio was 0.92 (95% CI, 0.91-0.93) compared with 1993-1994, and the 30-day readmission risk ratio was 1.11 (95% CI, 1.10-1.11). CONCLUSION: For patients admitted with HF during the past 14 years, reductions in length of stay and in-hospital mortality, less marked reductions in 30-day mortality, and changes in discharge disposition accompanied by increases in 30-day readmission rates were observed.

Individual Responsiveness to Physical Exercise Intervention in Acutely Hospitalized Older Adults.

We analyzed inter-individual variability in response to exercise among acutely hospitalized oldest-old adults. In this ancillary analysis of a randomized controlled trial, 268 patients (mean age 88 years) were assigned to a control (n = 125, usual care) or intervention group (n = 143, supervised exercise, i.e., walking and rising from a chair [1-3 sessions/day]). Intervention group patients were categorized as responders, non-responders, or adverse responders (improved, no change, or impaired function in activities of daily living [ADL, Katz index] from hospital admission to discharge, respectively). We analyzed the association between responsiveness to exercise and variables assessed at baseline (2 weeks pre-admission), admission, during hospitalization, at discharge, and during a subsequent 3-month follow-up. An impaired ADL function and worse nutritional status at admission were associated to a greater responsiveness, whereas a better ADL function at admission, longer hospitalization and lower comorbidity index were associated with a poorer response (p < 0.05). Adverse responders had worse outcomes at discharge and during the follow-up (e.g., impaired physical performance and greater fall number) (p < 0.05). Although exercise intervention helps to prevent ADL function decline in hospitalized oldest-old people, a number of them-particularly those with a better functional/health status at admission and longer hospitalization-are at higher risk of being adverse responders, which can have negative short/middle-term consequences.

Prognostic impact of anemia according to frailty status in elderly patients with acute coronary syndromes.

AIMS: Anemia is associated with poorer outcomes in patients with acute coronary syndromes (ACS), but the magnitude of this association in elderly patients remains poorly understood. No study has assessed the prognostic impact of anemia according to frailty status in this setting. METHODS: The LONGEVO-SCA registry included unselected ACS patients aged at least 80 years. A geriatric assessment was performed during hospitalization, including frailty assessment using the FRAIL scale. Anemia was defined by the WHO criteria. We evaluated the impact of anemia on 6-month mortality according to the presence of frailty. RESULTS: A total of 517 patients were assessed. Mean age was 84.3 years, and a total of 236 patients (45.6%) had anemia. Patients with anemia had a higher prevalence of comorbidities and higher prevalence of frailty (30.6 vs. 22.3%, P = 0.007). A total of 60 patients (12.1%) died at 6 months [40 with anemia (17.5%) and 20 without anemia (7.5%), P = 0.001]. Anemia was independently associated with mortality at 6 months in the whole cohort (hazard ratio 2.28, 95% CI 1.13-457, P = 0.021). The association of anemia and mortality was different according to frailty status, being significant in patients without frailty (hazard ratio 3.94, 95% CI 1.84-8.45, P = 0.001), but not in frail patients (hazard ratio 1.17, 95% CI 0.53-2.57, P = 0.705), (P value for interaction = 0.035). CONCLUSION: A high proportion of elderly patients with ACS have anemia, leading to a worse prognosis in the whole cohort. The association between anemia and mortality was especially significant in robust patients, whereas the poorer prognosis in frail patients was not modified by the presence of anemia.

FRAIL Scale also Predicts Long-Term Outcomes in Older Patients With Acute Coronary Syndromes.

OBJECTIVES: No previous studies have assessed the role of the FRAIL scale in predicting long-term outcomes in older patients with acute coronary syndromes (ACS). DESIGN, SETTING AND PARTICIPANTS: The multicenter observational LONGEVO-SCA registry included unselected patients ≥80 years of age with ACS from 44 centers. A comprehensive geriatric assessment was performed during hospitalization. MEASURES: Frailty was measured by the FRAIL scale. For the purpose of this study, main outcome measured was mortality or readmission at 24 months. RESULTS: A total of 498 patients were included. Mean age was 84.3 years. A total of 198 patients (33.1%) were prefrail and 135 (27.1%) frail. Patients who were prefrail and frail had a higher degree of comorbidities, and higher prevalence of disability, cognitive impairment, and nutritional risk. A total of 165 out of 498 patients (33.1%) died, and 331 patients (66.7%) died or were readmitted at 24 months. Both prefrailty and frailty were associated with a higher mortality compared with robust patients (P < .001). The incidence of mortality or readmission was also higher in patients who were prefrail or frail (P < .001). After adjusting for potential confounders, the association between frailty and mortality or readmission remained significant (hazard ratio 1.28 for prefrailty and hazard ratio 1.96 for frailty, P < .001). The FRAIL scale showed an optimal ability for predicting mortality or readmission (area under the receiver operating characteristics curve 0.86, 95% confidence interval 0.83‒0.89). The area under the receiver operating characteristics curve from the Global Registry of Acute Coronary Events risk score was 0.89. No significant differences were observed between both AUC values (P = .163). CONCLUSIONS AND IMPLICATIONS: The FRAIL scale independently predicted long-term outcomes in older patients with ACS. The predictive ability of this scale was comparable to the strongly recommended Global Registry of Acute Coronary Events risk score. Frailty assessment is mandatory for improving risk prediction in these complex patients.

Progressive edemas and generalized telangiectasia: A presentation of Intravascular B-cell Lymphoma.

Intravascular B-cell Lymphoma is a rare lymphoproliferative disorder with a none specific clinical presentation. The association of cutaneous telangiectasia-like lesions and elevated inflammatory markers should be guaranteed a skin biopsy.

Octogenarian women with acute coronary syndrome present frailty and readmissions more frequently than men.

BACKGROUND: A worse prognosis has been reported among women with acute coronary syndrome compared to men. Our aim was to address the role of frailty and sex in the management and prognosis of elderly patients with non-ST-segment elevation acute coronary syndrome. METHODS: A prospective registry in 44 Spanish hospitals including patients aged 80 years and older with non-ST-segment elevation acute coronary syndrome. Frailty assessment was performed using the FRAIL scale. RESULTS: Of a total of 535 patients, 207 (38.7%) were women. Mean age was 84.8±4.0 years, similar in men and women. A prior history of coronary artery disease was more common in men (146, 44.9%) than in women (46, 22.2%), P<0.001. Frailty was less frequent in men (65, 20.2%) than in women (77, 37.8%), P<0.001. Female sex was an independent predictor of death/hospitalisation (hazard ratio (HR) 1.7, 95% confidence interval (CI) 1.1-2.4) and of hospitalisation at 6 months (HR 1.6, 95% CI 1.04-2.4). In men, compared to non-frail patients, both a prefrail status (HR 3.47, 95% CI 1.22-9.89) and frailty (HR 3.19, 95% CI 1.08-9.43) were independently associated with higher mortality. In women only frailty was independently associated with higher mortality (HR 5.68, 95% CI 1.91-16.18, compared to prefrailty or robustness). Frailty was associated with readmissions in men (HR 3.34, 95% CI 1.79-6.22) but not in women. CONCLUSIONS: In octogenarians with acute coronary syndrome female sex was independently associated with death/hospitalisation at 6 months. Frailty was more common in women and was a predictor of poor prognosis. In men prefrailty also predicted a poor prognosis.

Most elderly patients hospitalized for heart failure lack the abilities needed to perform the tasks required for self-care: impact on outcomes.

AIM: To evaluate the abilities to perform essential tasks for heart failure (HF) self-management in elderly patients, and its influence on post-discharge prognosis. METHODS AND RESULTS: Overall, 415 patients ≥70 years old hospitalized for HF were included and followed during 1 year. The ability to perform six specific tasks (use of a scale, weight registration, diuretic identification, knowledge of salted foods, oedema identification, and treatment adjustment) was tested and distributed on terciles (T) of performance. Correlation with the self-administered questionnaire European HF Self-care Behaviour Scale (EHFScBS) was evaluated. The independent influence of self-care on 1-year mortality and readmission risks was calculated by Cox proportional hazards regression analysis. Mean age was 80.1 years. On average, patients could perform 2.9 ± 1.6 of self-care tasks, and only 5.3% could perform the six tasks correctly. Patients with previous HF self-care education had slight better performance (3.2 ± 1.6 vs 2.8 ± 1.6, P < 0.02). A weak correlation was found between EHFScBS and number of tasks correctly performed (r = -0.135; P = 0.006). One-year mortality in T1, T2, and T3 patients was 33.0%, 20.7%, and 14.1%, respectively (P = 0.002). Multivariable analysis showed T2 and T3 groups having a lower adjusted mortality risk compared with T1 [hazard ratio (HR) 0.58; 95% confidence interval (CI) 0.32-1.03; and HR 0.40; 95% CI 0.21-0.77, respectively], without differences in readmissions. CONCLUSION: Most elderly patients admitted for HF are unable to perform several essential tasks needed for HF self-care. Self-perception of care was poorly correlated with real ability, and poor self-care ability was associated with higher 1-year mortality risk.

Clinical and prognostic implications of delirium in elderly patients with non-ST-segment elevation acute coronary syndromes.

BACKGROUND: Elderly patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) may present delirium but its clinical relevance is unknown. This study aimed at determining the clinical associated factors, and prognostic implications of delirium in old-aged patients admitted for NSTE-ACS. METHODS: LONGEVO-SCA is a prospective multicenter registry including unselected patients with NSTE-ACS aged ≥ 80 years. Clinical variables and a complete geriatric evaluation were assessed during hospitalization. The association between delirium and 6-month mortality was assessed by a Cox regression model weighted for a propensity score including the potential confounding variables. We also analysed its association with 6-month bleeding and cognitive or functional decline. RESULTS: Among 527 patients included, thirty-seven (7%) patients presented delirium during the hospitalization. Delirium was more frequent in patients with dementia or depression and in those from nursing homes (27.0% vs. 3.1%, 24.3% vs. 11.6%, and 11.1% vs. 2.2%, respectively; all P < 0.05). Delirium was significantly associated with in-hospital infections (27.0% vs. 5.3%, P < 0.001) and usage of diuretics (70.3% vs. 49.8%, P = 0.02). Patients with delirium had longer hospitalizations [median 8.5 (5.5-14) vs. 6.0 (4.0-10) days, P = 0.02] and higher incidence of 6-month bleeding and mortality (32.3% vs. 10.0% and 24.3% vs. 10.8%, respectively; both P < 0.05) but similar cognitive or functional decline. Delirium was independently associated with 6-month mortality (HR = 1.47, 95% CI: 1.02-2.13, P = 0.04) and 6-month bleeding events (OR = 2.87; 95% CI: 1.98-4.16, P < 0.01). CONCLUSIONS: In-hospital delirium in elderly patients with NSTE-ACS is associated with some preventable risk factors and it is an independent predictor of 6-month mortality.
