Show moreThe rate of adverse health outcomes 90 days after an emergency department (ED) visit is high for older patients.A comprehensive geriatric assessment (CGA) can effectively identify patients at highest risk and improve outcomes. Unfortunately, the fast-paced environment and the medical condition of the acutely ill older patient make it virtually impossible to perform a CGA in all patients in the ED. Therefore, it was the aim of the present thesis to develop a screening instrument for the ED setting to identify older patients at high risk for adverse health outcomes, in order to target them for future interventions to preserve their independency and quality of life. In a multicenter prospective cohort study a total of 2629 older ED patients were included with a mean age of 79 years old. After 90 days 805 patients (30.6%) experienced functional decline or mortality. A new screeninginstrument to identify older ED patients at risk for adverse health outcomes was developed and validated: the APOP screener. The APOP screener adequately identifies older ED patients at highest risk for functional decline or mortality and is promising for clinical use. Show less

Show moreThe main aim of this thesis is to explore risk factors associated to an increased risk of adverse outcomes for heart failure (HF) patients and improve the early re-admission or mortality prediction in HF. Data from two studies (OPERA-HF study in the UK and SAPHIRE study in US) has been used to explore a wide range of variables as potential risk factors. We found that depression is a significant and independent predictor of all-cause mortality among HF patients. Depression was also significantly associated with recurrent events: unplanned readmission or mortality. Other psychosocial or non-clinical variables independently associated with increasing risk of recurrent events in the year following discharge after a HF hospital admission were: presence of frailty, moderate-to-severe anxiety, living alone and the presence of cognitive impairment. We then used data from the OPERA-HF study to develop a 30-day composite outcome model and to explore the added predictive value of non-clinical predictors to early outcomes: 30-day unplanned readmission or mortality. The performance of the model improved by including physical frailty and social support next to clinical variables. The transportability of the model to a different geography was proved in the external validation of the model on the SAPHIRE study data. Show less
