Electronic databases such as EPC and NPR may contain errors arising from coding (Hoddevik 2005), data entry, transfers to other hospitals, and faulty extraction of data (Lofthus et al. 2005).
Each patient contact with the SAM system would consist of three stages: data entry, data transfer, and patient self-management.
Suggestions for moving forward include a collaborative design of suitable data elements, data collection protocols, data quality assurance, research and evaluation training, and procedures for confidential data entry and transfer.
This often leads to multiple inefficiencies in information management, including: multiple instances of data elucidation, data duplication, missing information as well as multiplying the risks of erroneous data entry and transfer, contributing to patients' and clinicians' frustration, increased cost and potential adverse events and patient harm.
The database created in Epi-Info v 6.04 b was fed using double data entry and transferred to Stata 5.0© using Stata Transfer 4.0©.
UNMC data entry clerks transferred paper records dating from 1970 onward into iHRIS Qualify.
Two data entry specialists transferred the data into EpiData, a data management program; each double-entering the data to minimize miscoding.
The IDS's electronic databases captured all diagnoses during this time period; for diagnoses recorded on paper, data entry clerks transferred the information into the databases.
Electronic case report forms were used for data entry and transferred via the web to a central database located in the European Heart House, where they were edited for missing data, inconsistencies and outliers.
