Study of the Effect of Bacterial Resistance Monitoring in Clinical Microbiology Testing

Abstract

Objective: To observe and analyze the effect of bacterial resistance monitoring in clinical microbiology testing. Methods: 600 microbial specimens collected in our hospital in the past year (April 2021 to April 2022) were used as the test subjects of this study. The specimens were divided into Group A (control group) and Group B (research group), with 300 cases in each group. Group A consisted of blood culture specimens, while Group B consisted of sputum specimens. After the tests were completed, the rates of unfavorable and favorable results, bacterial species distribution, and bacterial drug resistance of the specimens in both groups were compared. Results: Among group A specimens, 29 cases were positive (9.67%) and 271 cases were negative (90.33%); among group B specimens, 99 cases were positive (33.00%) and 201 cases were negative (66.00%); the difference between the two groups of data was statistically significant (P < 0.05). As for the distribution of the types of bacteria, there were 472 cases of Gram-negative bacteria and 128 cases of Grampositive bacteria. Conclusion: Bacterial resistance monitoring is helpful in clinical microbiology testing. Through proper monitoring, bacterial resistance can be well understood. In this way, patients get to receive appropriate treatment measures and suitable antibacterial prescriptions, thereby improving the patient outcome.
