E-prescribing: attitudes and perceptions of community pharmacists in Puerto Rico.

E-prescribing may help reduce medical errors. Study objectives were to determine use, perceptions, and a model of adoption regarding e-prescribing. A questionnaire was developed and sent to pharmacists in Puerto Rico. Multiple regression analyses were used to test a model of influences on adoption. 438 pharmacists responded. The overall adoption model was significant. Perceived advantages had a positive influence on adoption. Pharmacist groups demonstrating higher adoption included: male > female, chain > independent, younger > older (all p < 0.05). Barriers had a negative influence (p = 0.01). The model employed here can help explain pharmacist adoption and integration of e-prescribing.
