Components of case management in caring for patients with dementia: a mixed-methods study

BACKGROUND

Case management has shown improvements in some health outcomes for dementia patients and their families. However, despite its benefits the components of case management in order to provide effective patient and family care remain unknown at present. Thus, the aim of this study is to identify the specific components of case management in caring for patients with dementia and to determine the necessary intensity of its deployment to enhance outcomes for these patients and their caregivers.

METHODS

Mixed-methods study with a qualitative phase to characterise forms of service provision, according to the case management components involved, followed by a quantitative phase to analyse the correlations between different patterns of service provision, adverse events in patients and caregiver overload. This study will be based on the variables described in the RANGE.COM register.

DISCUSSION

This research is expected to achieve a reproducible, evaluable set of interventions that can be modelled to optimise case management effectiveness for patients with dementia. Interactions between patients with dementia, their family caregivers and case management healthcare services, the components of these interactions and their association with the conditions of the individuals concerned are issues of great interest in the field of case management, which is constantly evolving.

Use of matching methods in observational studies with critical patients and renal outcomes. Scoping review

Introduction: The use of matching techniques in observational studies has been increasing and is not always used appropriately. Clinical experiments are not always feasible in critical patients with renal outcomes, and observational studies are an important alternative. Objective: Through a scoping review, determine the available evidence on the use of matching methods in studies involving critically ill patients and assessing renal outcomes. Methods: Medline, Embase, and Cochrane databases were used to identify articles published between 1992 and 2020 up to week 10, which studied different exposures in the critically ill patient with renal outcomes and used propensity matching methods. Results: Most publications are cohort studies 94 (94. 9 %), five studies (5. 1 %) were cross-sectional. The main pharmacological intervention was the use of antibiotics in seven studies (7. 1%) and the main risk factor studied was renal injury prior to ICU admission in 10 studies (10. 1%). The balance between the baseline characteristics assessed by standardized means, in only 28 studies (28. 2%). Most studies 95 (96 %) used logistic regression to calculate the propensity index. Conclusion: Major inconsistencies were observed in the use of methods and in the reporting of findings. A summary is made of the aspects to be considered in the use of the methods and reporting of the findings with the matching by propensity index.

Risk-adjusted early invasive strategy in patients with non-ST-segment elevation acute coronary syndrome in Intensive Cardiac Care Units

OBJECTIVE

Current guidelines recommend a risk-adjusted early invasive strategy (EIS) in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS). The present study assesses the application if this strategy, the conditioning factors and prognostic impact upon patients with NSTEACS admitted to Intensive Cardiac Care Units (ICCU).

DESIGN

A prospective cohort study was carried out.

SETTING

The ICCUs of 8 hospitals in Catalonia (Spain).

PATIENTS

Consecutive patients with NSTEACS between October 2017 and March 2018. The risk profile was defined by the European Society of Cardiology criteria.

INTERVENTIONS

EIS was defined as the performance of coronary angiography within the first 6hours in patients at very high-risk or within 24hours in high-risk patients.

OUTCOME VARIABLES

Mortality or readmission at 6 months.

RESULTS

A total of 629 patients were included (mean age 66.6 years), of whom 225 (35.9%) were at very high risk, and 392 (62.6%) at high risk. Most patients (96.2%) underwent an invasive strategy. EIS was performed in 284 patients (45.6%), especially younger patients with fewer comorbidities. These patients had a shorter ICCU and hospital stay, as well as a lesser incidence of ACS, revascularization and death or readmission at 6 months. After adjusting for confounders, the association between EIS and death or readmission at 6 months remained significant (hazard ratio: .66, 95% confidence interval .45-.97; P=.035).

CONCLUSIONS

The EIS was performed in a minority of NSTEACS admitted to ICCU, being associated with better outcomes.

Determinants of invasive strategy in elderly patients with non-ST elevation myocardial infarction

Background

Knowledge gaps across literature prevent current guidelines from providing the profile of elderly patients most likely to derive benefit from invasive strategy (IS) in non ST-elevation myocardial infarction (NSTEMI). Furthermore, the benefit of IS in a real-world elderly population with NSTEMI remains unclear. The aims of this study were to determine factors that lead the cardiologist to opt for an IS in elderly patients with NSTEMI, and to assess the impact of IS on the 6-month all-cause mortality.

Methods

This multicenter prospective study enrolled all consecutive patients aged ≥ 75 years old who presented a NSTEMI and were hospitalized in cardiology intensive care unit between February 2014 and February 2015. Patients were compared on the basis of reperfusion strategy (invasive or conservative) and living status at six months, in order to determine multivariate predictors of the realization of an IS and multivariate predictors of 6-month mortality.

Results

A total of 141 patients were included; 87 (62%) underwent an IS. The strongest independent determinants of IS were younger age [odds ratio (OR): 0.85, 95%-confidence interval (CI): 0.78–0.92; P < 0.001) and lower “Cumulative Illness Rating Scale-Geriatric” number of categories score (OR: 0.83, 95%CI: 0.73–0.95; P = 0.002). IS was not significantly associated with 6-month survival (OR: 0.80, 95%CI: 0.27–2.38; P = 0.69).

Conclusions

In real-world elderly patients with NSTEMI, younger patients with fewer comorbidities profited more often from an IS. However, IS did not modify 6-month all-cause mortality.
