Provider knowledge and performance in medication injection safety in anesthesia: A mixed method prospective crosses sectional study.

OBJECTIVES: Injection safety during anesthesia is a challenging health care issue in Iranian hospitals. Anesthesia is one of the most medication-intensive procedures in healthcare and injecting patients are an integral part of that care. The present study aimed to assess the status of medication injection safety practice in a teaching center.

DESIGN, SETTING, PARTICIPANTS: A prospective cross-sectional study was done in 2014-2015 at a 500-bed secondary level teaching hospital affiliated with Urmia University of Medical Sciences, Iran. The study population included providers of anesthesia in two groups of operating rooms (ORs) with different types of surgeries at the center. Data were collected using valid and reliable observation and a questionnaire instruments in two consecutive phases. Mann-Whitney U, Kruskal-Wallis, and Spearman correlation tests were used for data analyses.

RESULTS: A total of 345 injections were observed and recorded during the study period, 53% in group A ORs, and 47% in group B ORs. Eighty-two questionnaires were completed (96.5% response rate) to determine hospital injection practices and personal knowledge of injection safety. Adherence to safety requirements was observed in 58.5% of injections. Fifty five percent of respondents knew that hepatitis B, C, and HIV are blood borne diseases. Observed compliance with injection safety requirements was determined significant by OR groups (P = 0.00). Correlation was significant between observed injection safety practices by age and work experience (P = 0.00). The Kruskal-Wallis test showed a significant difference (P = 0.000) in observed safe injection practices among four job groups but not in reported adherence. Knowledge of respondents was significant by job groups about blood borne diseases and receiving three doses of hepatitis B vaccine.

CONCLUSIONS: The study revealed that some of safe injection procedures were well carried out in our ORs, but that others were not. The reported adherence of staff was acceptable but their actual practices were unsafe. It is suggested to implement audits, provide safer supplies, and complete Hepatitis B vaccination of injection providers.
