Lower Risk Of Rehospitalization Research Articles

Characterization of acute heart failure hospitalizations in a Portuguese cardiology department

Introduction and AimsWe describe the clinical characteristics, management and outcomes of patients hospitalized with acute heart failure in a south-west European cardiology department. We sought to identify the determinants of length of stay and heart failure rehospitalization or death during a 12-month follow-up period. Methods and ResultsThis was a retrospective cohort study including all patients admitted during 2010 with a primary or secondary diagnosis of acute heart failure. Death and readmission were followed through 2011.Of the 924 patients admitted, 201 (21%) had acute heart failure, 107 (53%) of whom had new-onset acute heart failure. The main precipitating factors were acute coronary syndrome (63%) and arrhythmia (14%). The most frequent clinical presentations were heart failure after acute coronary syndrome (63%), chronic decompensated heart failure (47%) and acute pulmonary edema (21%). On admission 73% had left ventricular ejection fraction <50%. Median length of stay was 11 days and in-hospital mortality was 5.5%. The rehospitalization rate was 21% and 24% at six and 12 months, respectively. All-cause mortality was 16% at 12 months. The independent predictors of rehospitalization or death were heart failure hospitalization during the previous year (Hazard ratio − HR − 3.177), serum sodium <135mmol/l on admission (HR 1.995) and atrial fibrillation (HR 1.791). Reduced left ventricular ejection fraction was associated with a lower risk of rehospitalization or death (HR 0.518). ConclusionsOur patients more often presented new-onset acute heart failure, due to an acute coronary syndrome, with reduced left ventricular ejection fraction. Several predictive factors of death or rehospitalization were identified that may help to select high-risk patients to be followed in a heart failure management program after discharge.

Incidence and Predictors of 30-Day Hospital Readmission Rate Following Percutaneous Coronary Intervention (from the National Heart, Lung, and Blood Institute Dynamic Registry)

Postdischarge outcomes after percutaneous coronary intervention (PCI) are important measurements of quality of care and complement in-hospital measurements. We sought to assess in-hospital and postdischarge PCI outcomes to (1) better understand the relation between acute and 30-day outcomes, (2) identify predictors of 30-day hospital readmission, and (3) determine the prognostic significance of 30-day hospital readmission. We analyzed in-hospital death and length of stay (LOS) and nonelective cardiac-related rehospitalization after discharge in 10,965 patients after PCI in the Dynamic Registry. From 1999 to 2006 in-hospital death rate and LOS decreased. Thirty-day cardiac readmission rate was 4.6%, with considerable variability over time and among hospitals. Risk of rehospitalization was greater in women and those with congestive heart failure, unstable angina, multiple lesions, and emergency PCI. Conversely, a lower risk of rehospitalization was associated with a larger number of treated lesions. Patients readmitted within 30 days had higher 1-year mortality than those free from hospital readmission. In conclusion, although in-hospital mortality and LOS after PCI have decreased over time, the observed 30-day cardiac readmission rate was highly variable and risk of readmission was more closely associated with underlying patient characteristics than procedural characteristics.

Optimism, Response to Treatment of Depression, and Rehospitalization After Coronary Artery Bypass Graft Surgery

Optimism has been associated with a lower risk of rehospitalization after coronary artery bypass graft (CABG) surgery, but little is known about how optimism affects treatment of depression in post-CABG patients. Using data from a collaborative care intervention trial for post-CABG depression, we conducted exploratory post hoc analyses of 284 depressed post-CABG patients (2-week posthospitalization score in the 9-item Patient Health Questionnaire ≥ 10) and 146 controls without depression who completed the Life Orientation Test - Revised (full scale and subscale) to assess dispositional optimism. We classified patients as optimists and pessimists based on the sample-specific Life Orientation Test - Revised distributions in each cohort (full sample, depressed, nondepressed). For 8 months, we assessed health-related quality of life (using the 36-item Short-Form Health Survey) and mood symptoms (using the Hamilton Rating Scale for Depression [HRS-D]) and adjudicated all-cause rehospitalization. We defined treatment response as a 50% or higher decline in HRS-D score from baseline. Compared with pessimists, optimists had lower baseline mean HRS-D scores (8 versus 15, p = .001). Among depressed patients, optimists were more likely to respond to treatment at 8 months (58% versus 27%, odds ratio = 3.02, 95% confidence interval = 1.28-7.13, p = .01), a finding that was not sustained in the intervention group. The optimism subscale, but not the pessimism subscale, predicted treatment response. By 8 months, optimists were less likely to be rehospitalized (odds ratio = 0.54, 95% confidence interval = 0.32-0.93, p = .03). Among depressed post-CABG patients, optimists responded to depression treatment at higher rates. Independent of depression, optimists were less likely to be rehospitalized by 8 months after CABG. Further research should explore the impact of optimism on these and other important long-term post-CABG outcomes.

Potential Prognostic Value of Handgrip Strength in Older Hospitalized Patients.

Objective measures of physical function are useful prognostic tools also for hospitalized elders. Low handgrip strength is predictive of poor outcomes and it can be assessed also in a sitting position, representing a potential alternative measure in bedridden patients. We evaluated grip strength prognostic value in hospitalized older patients. Prospective cohort study. Geriatric, medical ward of an academic medical center in Ferrara, Italy. Patients aged 65 and older (N = 88) admitted to the hospital for an acute medical condition. Patients were evaluated for grip strength at hospital admission and were re-evaluated at discharge. After discharge, they were followed every 3 months for 1 year by telephone interviews to assess new hospitalizations and vital status. The mean age of the sample was 77.3 years, 47% were women. At admission, mean height standardized handgrip strength was 15.7±5 kg/m; men had greater strength (p<0.001). There was a direct relationship of admission grip strength with BMI (p<0.05), serum albumin (p=0.07), and Short Physical Performance Battery score (p<0.05), and an inverse relationship with age (gender-adjusted p value <0.01). In multiple regression analysis, after adjustment for possible confounders, patients in third tertile of grip strength had a shorter hospital stay compared to those in the first tertile (β -2.8; p<0.05). Patients with higher grip strength at discharge also had a lower risk of rehospitalization or death over the follow-up, although the result was not statistically significant (OR: 0.68; 95% CI: 0.30-1.52). In older hospitalized medical patients, grip strength assessment might provide useful prognostic information.

Retrospective claims database analysis to determine relationship between renin-angiotensin system agents, rehospitalization, and health care costs in patients with heart failure or myocardial infarction

Background: Heart failure (HF) and myocardial infarction (MI) cause considerable morbidity and mortality, but the outcomes and health care costs related to adherence to treatment guidelines for HF and MI are not fully understood. Objectives: The aims of this study were as follows: (1) to determine the proportion of patients discharged from the hospital with a primary diagnosis of HF or MI who subsequently received prescriptions for American Heart Association/American College of Cardiology-recommended angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), also referred to as renin-angiotensin system agents; (2) to investigate the relationship between adherence to and persistence with ACEIs/ARBs and risk of rehospitalization; and (3) to assess the relationship between adherence to and persistence with ACEIs or ARBs, cardiovascular-related health care costs, and total health care costs. Methods: Using the prescription and medical service records of a large national pharmacy-benefit database, we conducted a retrospective analysis of patients discharged from the hospital with a primary diagnosis of HF or MI between July 1, 2003, and June 30, 2006. Medication adherence, persistence, rehospitalization risk, and health care costs during 1-year follow-up were measured. Logistic regression models were used to estimate the likelihood of rehospitalization for different levels of adherence and persistence. Generalized linear models were used to investigate the impact of adherence and persistence on total health care costs and cardiovascular-related health care costs. Results: A total of 799 HF and 696 MI patients were included in the analysis; 57.20% of HF patients and 59.20% of MI patients were prescribed an ACEI or an ARB after discharge from the hospital. The mean (SD) age was 65.7 (13.7) years in the HF group and 60.6 (10.7) years in the MI group. In both groups, men accounted for a greater proportion of the patients than women. In the HF group, adherence and persistence were associated with a lower likelihood of rehospitalization compared with nonadherence and nonpersistence ( P < 0.042 and P < 0.005, respectively). In the MI group, there was no significant difference in rehospitalization risk between those who were adherent and those who were not. However, among these patients, persistence was associated with a lower risk of rehospitalization than nonpersistence ( P < 0.036). Adherence and persistence were associated with lower health care costs (HF: P < 0.001 for all comparisons; MI: P < 0.019 for adherence and total cost, P = NS for persistence and total cost, P < 0.012 for adherence and cardiovascular cost, P < 0.031 for persistence and cardiovascular cost). Conclusion: Adherence to and persistence with ACEIs or ARBs may reduce the risk of rehospitalization in patients with HF or MI, thereby potentially reducing health care costs.

Discharge Education Improves Clinical Outcomes in Patients With Chronic Heart Failure

Although interventions combining patient education and postdischarge management have demonstrated benefits in patients with chronic heart failure, the benefit attributable to patient education alone is not known. We hypothesized that a patient discharge education program would improve clinical outcomes in patients with chronic heart failure. We conducted a randomized, controlled trial of 223 systolic heart failure patients and compared the effects of a 1-hour, one-on-one teaching session with a nurse educator to the standard discharge process. Subjects were contacted by telephone at 30, 90, and 180 days to collect information about clinical events, symptoms, and self-care practices. The primary end point of the study was the total number of days hospitalized or dead in the 180-day follow-up period. Subjects randomized to receive the teaching session (n=107) had fewer days hospitalized or dead in the follow-up period (0 and 10 days, median and 75th percentiles) than did controls (n=116, 4 and 19 days; P=0.009). Patients receiving the education intervention had a lower risk of rehospitalization or death (relative risk, 0.65; 95% confidence interval, 0.45 to 0.93; P=0.018). Costs of care, including the cost of the intervention, were lower in patients receiving the education intervention than in control subjects by 2823 dollars per patient (P=0.035). The addition of a 1-hour, nurse educator-delivered teaching session at the time of hospital discharge resulted in improved clinical outcomes, increased self-care measure adherence, and reduced cost of care in patients with systolic heart failure.

Predictors of noncompliance in patients with schizophrenia.

Around 50% of patients with schizophrenia do not fully comply with treatment, and noncompliance is linked to relapse, rehospitalization, poor outcome, and high economic costs. The health belief model views noncompliance as a decision made by the patient, arrived at after weighing the perceived risks and benefits of treatment. A MEDLINE search for the years 1980-2002 using combinations of the keywords schizophrenia, compliance, adherence, antipsychotics, tolerability, and side effects was used to identify articles investigating the factors influencing compliance in schizophrenia. Many factors influence compliance, including those that affect patients' beliefs about their illness and the benefits of treatment (e.g., insight into illness, belief that medication can ameliorate symptoms), perceived costs of treatment (e.g., medication side effects), and barriers to treatment (e.g., ease of access to treatment, degree of family or social support). Medication side effects that are distressing to patients and linked to noncompliance include extrapyramidal side effects, neuroleptic dysphoria, akathisia, sexual dysfunction, and weight gain. Compliance can be improved by cognitive-behavioral therapies, such as compliance therapy, and other psychosocial interventions associated with improved social functioning and a lower risk of rehospitalization. Treatment adherence may also be improved by use of atypical antipsychotics with few perceived side effects. By considering the factors leading to noncompliance and adopting a comprehensive strategy for improving compliance, encompassing psychosocial intervention and optimum choice of medication, the management of schizophrenia could be greatly improved.
