In terms of analysis, a limitation was inability to differentiate between what had occurred in the present visit and in an earlier visit with a patient. Therefore, when participants reported missed or delayed diagnosis, it was not clear whether the APN student missed the diagnosis and the preceptor identified it or whether the diagnosis had been missed or delayed from an earlier visit. Another analytic limitation related to lack of data on our respondents' APN specialty or their actual practice setting. Demographic information on our respondents would have allowed us to analyze patient safety issues by sample subgroups. The ability to describe patient safety issues by respondent type would have enhanced our analysis. Future research should include collection of this information. Although this project took place at a single school of nursing in New York City, which may limit generalizability, participants reported on their clinical experiences at multiple settings throughout New York City in a diverse patient sample.
