Dementia and the risk of short-term readmission and mortality after a pneumonia admission.

ABSTRACT:

Background

At time of discharge after a pneumonia admission, care planning for older persons with dementia is essential. However, care planning is limited by lack of knowledge on the short-term prognosis.

Aim

To investigate 30-day mortality and readmission after hospital discharge for pneumonia in persons with versus without dementia, and to investigate how these associations vary with age, time since discharge, and medication use.

Methods

Using the Danish registries, we investigated 30-day mortality and readmission in persons (+65 years) discharged after pneumonia in 2000-2016 (N = 298,872). Adjusted mortality rate ratios (aMRRs) and incidence rate ratios (aIRRs) were calculated for persons with versus without dementia, and we investigated if these associations varied with use of benzodiazepines, opioids, and antipsychotics, and with age and time since discharge.

Results

Among 25,948 persons with dementia, 4,524 died and 5,694 were readmitted within 30 days. The risk of 30-day mortality was 129% higher (95% CI 2.21-2.37) in persons with versus without dementia after adjustment for sociodemographic characteristics, admission-related factors, and comorbidities. Further, the highest mortality risk was found in persons with both dementia and use of antipsychotics (aMRR: 3.39, 95% CI 3.19-3.59); 16% of deaths in this group could not be explained by the independent effect of each exposure. In those with dementia, the highest aMRRs were found for the youngest and for the first days after discharge. The risk of 30-day readmission was 7% higher (95% CI 1.04-1.10) in persons with versus without dementia. In those with dementia, the highest aIRRs were found for the first days after discharge.

Conclusions

Dementia was associated with higher short-term mortality after pneumonia, especially in users of antipsychotics, and with slightly higher readmission, especially in the first days after discharge. This is essential knowledge in the care planning for persons with dementia who are discharged after a pneumonia admission.

Project description:AimsThe aim of this study was to assess the performance of these main scores in predicting prognosis in patients with heart failure (HF).Methods and resultsA total of 2008 patients who were admitted to the Fourth People's Hospital of Zigong, Sichuan, from December 2016 to June 2019 and diagnosed with HF were included in the study. We compared the prognostic predictive performance of Seattle Heart Failure Model (SHFM), Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC-HF) risk score, Get With the Guidelines-Heart Failure programme (GWTG-HF), Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure (ASCEND) risk scores, the Acute Decompensated Heart Failure National Registry (ADHERE) model, Barcelona Bio-Heart Failure (BCN-Bio-HF) risk calculator, and Gruppo Italiano per lo Studio della Streptochinasi nell'Infarto Miocardico-Heart Failure (GISSI-HF) for the endpoints. The primary endpoint was 1 year all-cause mortality and the secondary endpoint was the incidence of 28 day readmission post-discharge. At 1 year follow-up, 44 (2.21%) patients with HF died. Discrimination analyses showed that all risk scores performed reasonably well in predicting 1 year mortality, with areas under the receiver operating characteristic curve (AUCs) fluctuating between 0.757 and 0.822. GISSI-HF showed the best discrimination with the AUC of 0.822 (0.768-0.876), followed by MAGGIC-HF, BCN-Bio-HF, ASCEND, SHFM, GWTG-HF, and ADHERE with AUCs of 0.819 (0.756-0.883), 0.812 (0.758-0.865), 0.802 (0.742-0.862), 0.787 (0.725-0.849), 0.762 (0.684-0.840), and 0.757 (0.681-0.833), respectively. All risk scores were similarly predictive of 28 day emergency readmissions, with AUCs fluctuating between 0.609 and 0.680. Overestimation of mortality occurred in all scores except the ASCEND. The risk scores remained with good prognostic discrimination in patients with biventricular HF and in the subgroup of patients taking angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker.ConclusionsCurrently assessed risk scores have limited clinical utility, with fair accuracy and calibration in assessing patients' 1 year risk of death and poor accuracy in assessing patients' risk of readmission. There is a need to incorporate more patient-level information, use more advanced technologies, and develop models for different subgroups of patients to achieve more practical, innovative, and accurate risk assessment tools.

Project description:BackgroundOlder adults admitted to an emergency department (ED) who are dependent on homecare may be especially challenged with respect to readmission and mortality. This study aimed to assess whether receiving homecare prior admission was associated with readmission or mortality within 30 days of a short ED admission and to explore whether the amount of homecare received was associated with an increased risk of readmission or mortality.MethodsThis nationwide register-based cohort study included patients aged 65 or above who were admitted to an ED at any Danish hospital from 1 December 2016 to 30 November 2017 and discharged within 48 h. Data were extracted from national registers through Statistics Denmark. Homecare was categorized into groups; patients without homecare and three groups according to the amount of homecare received per week. Logistic regression analyses were used to explore the association between the four homecare groups and outcomes, readmissions and mortality.ResultsIn total, 80,517 patients (51% female, median age 75 years) were included in the study. Overall, 64,886 patients without homecare, 15,631 (19%) patients received homecare (64% female, median age 83 years), of which 4938 patients received homecare ≤30 min, 4033 received > 30 min to ≤120 min and 6660 received > 120 min per week. The risk of readmission and mortality increased concurrently with the minutes of homecare received: Patients receiving homecare > 120 min per week had the highest odds ratios (ORs) for readmission within 30 days (OR 1.8 95% CI: 1.7-1.9) and mortality within 30 days (OR 4.5 95% CI: 4.1-4.9) compared with patients without homecare.ConclusionReceiving homecare was associated with an increased risk of readmission and death following a short ED admission. Collaboration between the ED and primary health care sector in relation to rehabilitation and end-of-life care is essential to improve quality of care for older adults who receive homecare, particularly those receiving homecare > 2 h a week, because of their increased risk of readmission and mortality.

Project description:The timing of 30-day pediatric readmissions is skewed with approximately 40% of the incidents occurring within the first week of hospital discharges. The skewed readmission time distribution coupled with delay in health information exchange among healthcare providers might offer a limited time to devise a comprehensive intervention plan. However, pediatric readmission studies are thus far limited to the development of the prediction model after hospital discharges. In this study, we proposed a novel pediatric readmission prediction model at the time of hospital admission which can improve the high-risk patient selection process. We also compared proposed models with the standard at-discharge readmission prediction model. Using the Hospital Cost and Utilization Project database, this prognostic study included pediatric hospital discharges in Florida from January 2016 through September 2017. Four machine learning algorithms-logistic regression with backward stepwise selection, decision tree, Support Vector machines (SVM) with the polynomial kernel, and Gradient Boosting-were developed for at-admission and at-discharge models using a recursive feature elimination technique with a repeated cross-validation process. The performance of the at-admission and at-discharge model was measured by the area under the curve. The performance of the at-admission model was comparable with the at-discharge model for all four algorithms. SVM with Polynomial Kernel algorithms outperformed all other algorithms for at-admission and at-discharge models. Important features associated with increased readmission risk varied widely across the type of prediction model and were mostly related to patients' demographics, social determinates, clinical factors, and hospital characteristics. Proposed at-admission readmission risk decision support model could help hospitals and providers with additional time for intervention planning, particularly for those targeting social determinants of children's overall health.
