Music in the acute preoperative nursing care — A mixed-method pilot study what level of evidence is this study

The level of evidence of a study is determined by the type of study design used. In the case of a mixed-method pilot study, it typically falls under Level II-3: Evidence obtained from multiple time series with or without the intervention. Dramatic results in uncontrolled trials might also be regarded as this type of evidence.

Here are the steps to determine the level of evidence:

1. Identify the Study Design: The study design is a mixed-method pilot study. Mixed methods combine qualitative and quantitative research methods in a single study. A pilot study is a small-scale preliminary study conducted to evaluate feasibility, time, cost, adverse events, and effect size to predict an appropriate sample size and improve upon the study design prior to performance of a full-scale research project.

2. Match the Study Design to the Level of Evidence: Different study designs correspond to different levels of evidence. Randomized controlled trials are considered the highest level of evidence, followed by cohort studies, case-control studies, case series/case reports, and expert opinion. Mixed-method studies can fall under different levels of evidence depending on their design, but generally, they are considered Level II-3.

3. Consider the Quality of the Study: The level of evidence is also influenced by the quality of the study. This includes factors like the sample size, the use of control groups, the consistency of the results, and the methodology used to collect and analyze data. Without more information about the specific study, it's hard to make a definitive judgement about its quality.

So, based on the information given, the "Music in the acute preoperative nursing care — A mixed-method pilot study" would likely be considered a Level II-3 evidence study. However, a more accurate assessment could be made with more information about the study's design and execution.
