J Am Med Inform Assoc 2014;21:98491. doi:10.1136/amiajnl-2014-Research and applicationsWhile conducting MSA to make a valid Mokken scale needs that 4 assumptions are met (unidimensionality, monotonicity, neighborhood stochastic independence, and item invariant ordering), the particular statistic from MSA that we use–the Loevinger H coefficient–does not rest on any assumptions regarding the structure of your data or the connection in between products.eight 9 Loevinger H is basically a descriptive statistic that may be generated as part of MSA to capture the degree of homogeneity in item sequencing. Our analyses do, even so, rest around the assumption that there is a dominant latent factor driving sequencing of hospital EHR adoption, which inside the context of our study may very well be conceived of as hospital capability to implement an EHR system. To confirm that our data met this assumption, we performed an exploratory factor evaluation to make sure that there was a dominant latent element and applied the rest-score system to assess no matter whether there had been any violations in monotonicity (ie, a monotonic enhance in the probability of positively responding to an item with a rise within the variety of other optimistic item responses).six 7 9 Final results of the exploratory element analysis showed an eigenvalue from the initially element (9.34) that was more than 3 occasions that of your second factor (three.09), and there have been no violations on the monotonicity assumption. across functions statistically differed primarily based on hospital characteristics, we calculated regular errors (SEs) for the homogeneity scores making use of the mokken statistical package available in R.12 13 Lastly, we qualitatively assessed irrespective of whether the functions necessary for stage 1 meaningful use `core’ criteria are these that are adopted early by hospitals. For the assessment, we identified a subset of 11 functions which might be emphasized inside the stage 1 criteria (see on the web supplementary appendix table A2). We anticipated that meaningful use will be unlikely to have a substantial impact on how hospitals approach functions which are extremely adopted with higher homogeneity scores. In contrast, functions which have low or moderate adoption prices and low homogeneity might be probably the most affected by meaningful use, considering the fact that there’s apparent variation in when hospitals choose to or are in a position to implement the function. Functions that have low adoption rates and higher homogeneity, alternatively, are most likely to be the most challenging for hospitals to implement early in response to meaningful use, because successful implementation of these functions may well rely on the presence of other, a lot more basic EHR functions.Analytic approachTo address our 1st investigation question, we assessed the existence of a common sequence of EHR adoption by calculating Loevinger H coefficients for person EHR functions also as across al.
