Which of the following is NOT a limitation of using existing case records as the basis for practice evaluations?

Case records are often an excellent source of information for evaluating the impacts of services. They are existing sources of data so there is no additional cost or time associated with their collection. However, there are a few limitations. If looking at records completed by multiple workers, there may be inconsistencies in recording styles or detail that may impact on evaluations. Also, information of interest may not be contained in the records and evaluations would need to be limited to only information that is explicitly stated, which may not reflect all progress that has been made. In addition, the opinions about how a client views both the process and outcomes of service delivery are also critical and may not be fully captured in the record.
