That is a very good question. In Meaningful Use II there is a really big push for interoperable data. That is the sharing of data between healthcare facilities to provide a complete picture of an individual health record. It all sounds really great and would be if healthcare facilities had more accurate ways of identifying their patients.
The current methods of identifying patients with demographics lead to misidentification of patients, duplicate records and the inaccurate merging of records. Healthcare provider organizations report that between 8 and 13 percent of their medical records are duplicated — and sometimes as high as 22 percent. In multi-facility environments, where disparate application systems are integrated, the percentage of duplicates can surpass 30 percent.
Solving this issue can be frustrating, time consuming and expensive. Software packages are available to compare patient records from disparate systems and indicate the probability that two records are duplicates, unique or potentially duplicate. These packages use probabilistic matching algorithms that incorporate phonetic similarities, variances in typographical entries and dates, and aliases. By determining the relative “weight” of specific comparators, the patient identity process improves significantly.
However, until you have absolute healthcare identification, you will never prevent duplicate records and will always be in a constant loop of data cleansing. By using a combination of smart cards and biometric identification, you can confidently identify the patient during the registration process. You don’t have to depend on what the patient tells you to verify who they are; the biometric will do that for you. You can record the time and dates that a patient receives care, preventing both identify theft and billing fraud.
As I stated at the beginning, you can’t share data between systems if you don’t know who your patients are. How does your healthcare facility provide absolute healthcare identification? To find out how we do it, check out www.privasent.com.
