(1) Background: The use of standardized tools is regarded as the basis for an evidence-based assessment. The tools enable monitoring of complex events and the effectiveness of adopted interventions. Some healthcare facilities use standardized tools such as the Morse Fall Scale, but many use non-standardized tools created based on patient needs. Our study question was, why are non-standardized tools used when standardized tools are more beneficial and can be statistically evaluated and compared to other results; (2) Methods: We used a quantitative, non-standardized questionnaire to survey 1200 nurses, which was representative sample for the entire Czech Republic. All questionnaires were assessed in two phases (a) the frequency evaluation and descriptive analysis, and (b) hypotheses testing and correlation analyses; (3) Results: We found that the Conley Scale, Barthel test, and IADL test were preferred by many nurses. Furthermore, we found that nurses using standardized assessment scales noticed risk factors significantly more frequently but regarded the increased complexity of care to be psychologically demanding. (4) Conclusions: In patients with physical disabilities, both types of tools (internal non-standardized and standardized) are used to assess the risk of falls and independence; nurses generally welcomed the increase use of standardized tools in their facilities.
