Abstract:

Background: Drug dosage calculation and administration is important function of nurses. The key professional role of nurses is to ensure safe drug dosage calculation while performing medication administration. Medication errors are a common cause of adverse events that may result due to wrong drug dosage calculation. The assessment of nurse's knowledge related to drug dosage calculation has not been conducted at the time of commencing their employment in the study hospital.

Purpose: The purpose of this study was to assess the drug dosage calculation knowledge and proficiency among our newly hired nurses before and after the training session.

Method and design: Participatory Action Research (PAR) approach was selected using pre and post -test to assess the newly hired nurse's knowledge and proficiency related to drug dosage calculation. Data was collected after IRB approval at private tertiary hospital, Islamabad, Pakistan.

Sample: Purposive sampling technique was adopted (n=135) all nurses on their commencement of employment from July 2016 to October 2016 participated in the study after the informed consent.

Findings: The study results showed the significant improvement in drug dosage calculation knowledge and proficiency among the study participants while comparing pre-test and post-test results.

Conclusion: The study concluded in the light of pre-test and post-test results that there is an intense need to review the nurse's drug dosage calculation knowledge and proficiency at the time of employment as nurses are key player in drug preparation and administration.

Keywords: Drug dosage calculation, conceptual skills in mathematics, proficiency, an evaluation of drug dosage, essential competency, dosage calculation knowledge, numeracy.
