Background: Antimicrobial resistance (AMR) poses a major threat to global public health. Antimicrobial stewardship (AMS) programs aim to optimize antimicrobial use and improve patient outcomes while limiting the emergence of resistance. Healthcare professionals play a central role in the success of antimicrobial stewardship programs; however, gaps in knowledge, attitude, and clinical practices may compromise effective implementation.
Methods: A hospital-based cross-sectional observational study was conducted at a tertiary care teaching hospital in South India. A validated, structured questionnaire assessing knowledge, attitude, and practice (KAP) regarding antimicrobial stewardship was administered to healthcare professionals, including medical students, residents, consultants, nursing staff, and faculty members. The questionnaire consisted of 15 items with 58 sub-sections evaluated using a 5-point Likert scale. Data were analyzed using SPSS software. Descriptive statistics were used to summarize responses, and Pearson’s Chi-square test was applied to determine associations between categorical variables. A p-value <0.001 was considered statistically significant.
Results: Overall, 62% of participants demonstrated good knowledge of antimicrobial stewardship principles, while 71% exhibited a positive attitude toward antimicrobial stewardship programs. However, only 48% showed good antimicrobial prescribing practices. Consultants and senior residents demonstrated significantly better knowledge and practice compared to junior clinicians and nursing staff. Case-based scenarios revealed inappropriate antibiotic use in self-limiting conditions such as acute bronchitis, uncomplicated diarrhea, and asymptomatic bacteriuria. A significant association was observed between higher knowledge scores and appropriate antimicrobial practices (χ² = 12.4, p = 0.001).
Conclusions: Although knowledge and attitudes toward antimicrobial stewardship were generally favorable, a substantial gap was observed in clinical practice. Strengthening antimicrobial stewardship programs through continuous education, multidisciplinary collaboration, and institutional support is essential to improve antimicrobial use and combat antimicrobial resistance.
Antimicrobial stewardship (AMS) is a critical component of healthcare systems aimed at ensuring the rational use of antimicrobial agents. Along with infection prevention and control and patient safety, AMS forms one of the three pillars of healthcare quality improvement. Despite the availability of effective antimicrobials, inappropriate prescribing practices have contributed to the rapid emergence of antimicrobial resistance (AMR), resulting in increased morbidity, mortality, and healthcare costs worldwide1,2,3.
Studies from India and other low- and middle-income countries have reported inappropriate antimicrobial prescribing driven by diagnostic uncertainty, patient expectations, and lack of awareness of stewardship principles. Understanding healthcare professionals’ knowledge, attitudes, and practices toward antimicrobial stewardship is essential for designing effective interventions4,5. This study aimed to assess the KAP of healthcare professionals regarding antimicrobial stewardship in a tertiary care hospital.
METHODS
Study Design and Setting
This was a hospital-based cross-sectional observational study conducted at Kamineni Hospital, Kamineni Academy of Medical Sciences and Research Centre (KAMSRC), LB Nagar, Hyderabad, India.
Study Participants
The study included final-year medical students, junior residents, senior residents, consultants, nursing staff, and faculty members involved in patient care.
Study Tool
A validated questionnaire comprising 15 questions with 58 sub-sections was used to assess knowledge (29 items), attitude (5 items), and practice (24 items) related to antimicrobial stewardship. Responses were recorded on a 5-point Likert scale ranging from “strongly disagree” (1) to “strongly agree” (5).
Scoring and Data Analysis
Scores were categorized as good (≥75%), average (50–74%), or poor (<50%). Data were analyzed using SPSS software. Descriptive statistics were presented as frequencies and percentages. Pearson’s Chi-square test was used to assess associations, with statistical significance set at p <0.05.
RESULTS
Overall KAP Performance
Good knowledge of antimicrobial stewardship principles was observed in 62% of participants, while 71% demonstrated a positive attitude toward antimicrobial stewardship programs. In contrast, only 48% of respondents exhibited good antimicrobial prescribing practices.
Profession-wise Analysis
Consultants and senior residents had significantly higher knowledge and practice scores compared to medical students, junior residents, and nursing staff. Practice gaps were particularly evident in routine antimicrobial review, de-escalation, and multidisciplinary consultation8,9.

Higher knowledge scores were significantly associated with better antimicrobial prescribing practice
Case-Based Practice Assessment
Inappropriate antimicrobial use was commonly observed in self-limiting conditions such as acute bronchitis and uncomplicated diarrhea. Overuse of antibiotics for surgical prophylaxis was also reported.
Association Between Knowledge and Practice
A statistically significant association was found between higher knowledge scores and appropriate antimicrobial prescribing practices (χ² = 12.4; p = 0.001).
DISCUSSION
This study demonstrates that although healthcare professionals possess adequate knowledge and favorable attitudes toward antimicrobial stewardship, these do not consistently translate into optimal clinical practices. Similar findings have been reported in previous studies from India and other countries, highlighting a persistent gap between knowledge and practice10,11,12.
The lower practice scores among junior clinicians and nursing staff emphasize the need for targeted educational interventions14,15. Limited multidisciplinary involvement and reliance on empirical prescribing further highlight structural barriers to effective stewardship implementation. Strengthening antimicrobial stewardship programs through continuous training, audit and feedback, and real-time microbiology support is essential.
CONCLUSIONS
Healthcare professionals demonstrated good awareness and positive attitudes toward antimicrobial stewardship; however, antimicrobial prescribing practices remain suboptimal. Institutional strengthening of antimicrobial stewardship programs, continuous professional education, and multidisciplinary collaboration are critical to improving antimicrobial use and combating antimicrobial resistance.
