Evaluation of Intravenous Ranitidine on Gastric pH in Critically Ill Pediatric Patients

Analysis of stress ulcer prophylaxis drug regimentation in surgical patients

OBJECTIVES

The World Health Organization (WHO) estimated that more than 50% of drugs were prescribed incorrectly, including stress ulcer prophylaxis (SUP) drugs. Prescribing SUP drugs in incorrect doses and frequencies are considered irrational, and may affects to the effectivity of the therapy. This research aimed to assess the appropriateness of the SUP drugs regimentation in the inpatient surgery room at Dr. Soetomo Hospital, Surabaya, Indonesia.

METHODS

This research was cross-sectional study and conducted for 4 weeks in 2019 in the inpatient surgery room of Dr. Soetomo Hospital. The population was SUP drugs that were prescribed in inpatient surgery room. Those SUP drugs with indications for the prevention of stress-induced ulcers that complied to the terms listed on the American Society of Health-System Pharmacists (ASHP) were included as the samples, and vice versa. The samples then assessed for their regimentation appropriateness using the dose and frequency standard of ASHP.

RESULTS

There were 224 dose units taken as sample, from the total population of 1,404 SUP drugs. The result showed that as much as 48.2% of SUP medications were given to the patients in inappropriate regimentation. Of that number, all ranitidine injection were inappropriately regimented. On the contrary all omeprazole injection dose units were appropriately regimented, meanwhile the amount of appropriate regimentation of sucralfate suspension were 74.6%.

CONCLUSIONS

According to ASHP standard, the SUP drugs in the inpatient surgery room at Dr. Soetomo Hospital were mostly given in inappropriate regimentation. Further research is needed to explore how will those inappropriate regimentation affect on the efficacy of therapy in the patients.
