Final answer:
The improvement team should first identify the cause of variances from evidence-based interventions in order to reduce resident falls within the nursing care center.
Step-by-step explanation:
In order to reduce resident falls within the nursing care center, the improvement team should first identify the cause of variances from evidence-based interventions. This is important because understanding the root causes of falls will help the team develop targeted solutions. Once the causes are identified, the team can then revise protocols and procedures to address those specific issues. Obtaining benchmark data from other nursing care centers in the area and analyzing grievances and liability claims can be done later in the process to further inform the improvement efforts.
