Socio-demographic and -economic factors associated with 30-day readmission for conditions targeted by the hospital readmissions reduction program: a population-based study.

BACKGROUND: Early hospital readmissions remain common in patients with conditions targeted by the CMS Hospital Readmission Reduction Program (HRRP). There is still no consensus on whether readmission measures should be adjusted based on social factors, and there are few population studies within the U.S. examining how social characteristics influence readmissions for HRRP-targeted conditions. The objective of this study was to determine if specific socio-demographic and -economic factors are associated with 30-day readmissions in HRRP-targeted conditions: acute exacerbation of chronic obstructive pulmonary disease, pneumonia, acute myocardial infarction, and heart failure. METHODS: The Nationwide Readmissions Database was used to identify patients admitted with HRRP-targeted conditions between January 1, 2010 and September 30, 2015. Stroke was included as a control condition because it is not included in the HRRP. Multivariate models were used to assess the relationship between three social and economic characteristics (gender, urban/rural hospital designation, and estimated median household income within the patient's zip code) and 30-day readmission rates using a hierarchical two-level logistic model. Age-adjusted models were used to assess relationship differences between Medicare vs. non-Medicare populations. RESULTS: There were 19,253,997 weighted index hospital admissions for all diagnoses and 3,613,488 30-day readmissions between 2010 and 2015. Patients in the lowest income quartile (≤$37,999) had an increased odds of 30-day readmission across all conditions (P < 0.0001). Female gender and rural hospital designation were associated with a decreased odds of 30-day readmission for most targeted conditions (P < 0.05). Similar findings were also seen in patients ≥65 years old. CONCLUSIONS: Socio-demographic and -economic factors are associated with 30-day readmission rates and should be incorporated into tools or interventions to improve discharge planning and mitigate against readmission.

First administration of the Fc-attenuated anti-ß amyloid antibody GSK933776 to patients with mild Alzheimer's disease: a randomized, placebo-controlled study.

OBJECTIVE: To assess the safety, tolerability, pharmacokinetics, and pharmacodynamics of the Fc-inactivated anti-ß amyloid (Aß) monoclonal antibody (mAb) GSK933776 in patients with mild Alzheimer's disease (AD) or mild cognitive impairment (MCI). METHODS: This was a two-part, single blind, placebo-controlled, first-time-in-human (FTIH) study of single (n = 18) and repeat dose (n = 32) intravenous GSK933776 0.001-6 mg/kg (ClinicalTrials.gov: NCT00459550). Additional safety data from an open-label, uncontrolled, single dose study of intravenous GSK933776 1-6 mg/kg (n = 18) are included (ClinicalTrials.gov: NCT01424436). RESULTS: There were no cases of amyloid-related imaging abnormalities-edema (ARIA-E) or -hemorrhage (ARIA-H) after GSK933776 administration in both studies. Three patients across the two studies developed anti-GSK933776 antibodies. Plasma GSK933776 half-life (t1/2) was 10-15 days after repeat dosing. After each of three administrations of GSK933776, plasma levels of total Aß42 and Aß increased whereas plasma levels of free Aß decreased dose dependently; no changes were observed for placebo. For total Aß42 the peak:trough ratio was ≤2 at doses ≥3 mg/kg; for total Aß the ratio was ≤2 at 6 mg/kg. CSF concentrations of Aß showed increases from baseline to week 12 for Aß X-38 (week 12:baseline ratio: 1.65; 95%CI: 1.38, 1.93) and Aß X-42 (week 12:baseline ratio: 1.18; 95%CI: 1.06, 1.30) for values pooled across doses. CONCLUSION: In this FTIH study the Fc-inactivated anti-Aß mAb GSK933776 engaged its target in plasma and CSF without causing brain ARIA-E/H in patients with mild AD or MCI. TRIAL REGISTRATION: ClinicalTrials.gov NCT00459550.

Evaluation of a model of nursing care for older patients using participatory action research in an acute medical ward.

AIMS AND OBJECTIVES: The main aim of this study was to improve the quality of nursing care for older acutely ill hospitalized medical patients through developing, implementing and evaluating a new model of care using a participatory action research process. BACKGROUND: One of the challenges of nursing today is to meet the health-care needs of the growing older population. It is important to consider what quality of nursing care means to older patients if nurses are to address gaps between their own perceptions and those of older patients themselves and to consider conceptual models of care appropriate for older patients care in order to improve the quality of care provided. DESIGN: This study is a mixed method triangulated study, involving the use of both quantitative and qualitative methods through participatory action research methodology to establish an evidence-base for an evolving model of care. METHODS: The model was tested on 60 acutely ill patients aged at least 65 years. The medical ward nurses selected a key reference group including the researcher to facilitate the participatory action research process to develop, implement and evaluate a new model of care based on Orem's self-care model incorporating the Nurses Improving Care to Health System Elders Faculty (Am J Nurs 1994; 94:21) medication protocol to improve the nursing care provided for acutely ill older patients. RESULTS: The participatory action research process resulted in improved heath-care outcomes for the patients, such as significant improvements in activities of daily living capabilities between admission to discharge, significant improvements in knowledge levels regarding their medication regimes, as well as increased satisfaction with nursing care activities as perceived by older patients and nursing staff. The implementation of educational sessions during the model of care improved the older patient's functional activities and knowledge levels of their medication regime prior to discharge. In addition, by repeatedly explaining procedures, nurses became more involved with their individual patient's care, developing a patient-centred care relationship based on Orem's self-care model. CONCLUSIONS: This study demonstrates the efficacy of a new model of nursing care in improving the quality of nursing care for older patients in the acute medical ward setting. RELEVANCE TO CLINICAL PRACTICE: This study is significant because of its evidence-base and demonstrates how the participatory action research process empowered nurses to make sustainable changes to their practice. The nurses in the study wanted to affect change. The planned change was not dictated by management, but was driven by the clinical nursing staff at the 'grass roots' level. Therefore, being involved in the decision-making process provided an incentive to actively implement change.
