Knowledge of and attitudes toward heel prick screening for sickle cell disease in Saint Lucia

In the Caribbean country of Saint Lucia, umbilical-cord-blood screening for sickle cell disease (SCD) was the testing method that health care workers (HCWs) on the maternity wards of the hospitals preferred until the new heel prick (HP) testing method was introduced in the country in 2014. This SCD study sought to assess HCWs' knowledge of and attitude toward HP screening and also determine new mothers' favorability toward HP screening.

A total of 70 HCWs and 132 new mothers answered survey questionnaires in three hospitals. In addition, four focus group discussions were held, two with HCWs and two with the mothers.

Among the HCWs interviewed, 85.7% of them had knowledge of the HP test. However, only 25.7% had attended training sessions on the procedure. Among the HCWs, 64.3% of them felt the HP test should be mandatory, 27.1% said it should not be mandatory, and 8.6% did not know if it should be mandatory. In their focus groups, the HCWs said they believed the mothers would accept the HP method. For their part, 22.0% of the mothers said they had heard about the HP test, and 63.6% reported knowing the reason why the baby would be tested. Further, 83.3% indicated that the test would be beneficial for the baby. In addition, 88.6% of the mothers said that more information on the HP test was needed. In their focus group discussions, the mothers said they were generally not concerned about the pain the heel prick method might cause the baby.

The HCWs' knowledge of the HP screening method was high. The mothers trust HCWs, and the mothers would accept the HP procedure irrespective of their knowledge of the test and any discomfort associated with this screening method.
