Matrix Table for the State of the Science Project Example
| Year | Problem/Purpose | Design (Quantitative or Qualitative, Mixed Methods) | Sample | Methods | Findings | Implications | Limitations |
| 1.
| 2018 | To determine if changes occurred in nurses’ knowledge regarding delirium and risk factors after educational intervention | (Quantitative quality improvement project ) | Convenience sample of 34 ICU nurses at one 28-bed unit/ medical center | Quasi-experimental: Pre/Post Test | Statistical improvement in overall recognition scores after educational intervention | Knowledge did improve after education. Before intervention, nurses showed limited awareness of identifying delirium and what tools to use | Single unit, low participation, time constraints, data availability, exclusion of clinical lit review in intervention design |
| 2.
| 2019 | To systematically review the published literature to determine the effect of educational interventions on recognition of delirium | Systematic Review | 26 studies selected | Literature review, identification of studies meeting review criteria, classification of studies by PRECEDE model, rating studies by levels of Kirkpatrick Model of Learning Outcomes | Interventions can be grouped into four types: Type 1 (9) studies showed greater knowledge and self-confidence but with a high degree of variability in reporting the results, Type 2 (11) studies significant knowledge gain and improved confidence in recognizing delirium, and some demonstrated behavior modification in identifying delirium and improved recognition of delirium, Type 3 (1) study did not show improvement, Type 4 (5) | Using a Include a single multifaceted intervention or a combination of interventions across all three type variety of strategies for nursing education on the recognition of delirium is most effective and were more likely to result in a changes in staff practice and health outcomes | Difficulty in combing results and drawing conclusion with studies using various approaches, not possible to include unpublished studies that increased risk of publication bias, exclusion of some studies because of inadequate description of educational interventions |
