Introduction: Health care associated infections (HAIs) are likely to be the most common complication of hospital care. World Health Organization (WHO) estimates these infections to occur among 7% - 12% of the hospitalized patients globally, with more than 1.4 million people suffering from infectious complications acquired in the hospital at any time. Keeping this in mind, the present study was conducted to delineate the level of knowledge, attitudes, and practices (KAP) for the use of proper disinfection procedures among the final year undergraduate medical students in a tertiary care hospital and teaching institute. Methodology: Present study was conducted at Government Medical College, Surat, a tertiary care hospital and teaching institute. The participants who gave consent were provided with a pre-tested questionnaire that included several questions on knowledge attitude and practices on hospital acquired infections and its control practices. Analysis of the answers was done based on KAP score. Result: 80 students who consented were included in the study. 75% of the study population had correct knowledge about the most common health care associated infections (HAIs), being infection of venous access, urinary tract infection, respiratory infections and surgical site infections, based on their current knowledge on hospital acquired infections. Majority of study participants agreed with the fact that the inappropriate application of disinfection procedures increases the risk for a health care worker of either acquiring or transmitting a HAI from/to a patient. >90% participants had a good attitude towards risk of getting or transmitting any infectious disease by a Health care worker (HCW) while working and the utility of the application of disinfection procedures during work would reduce the rates of HAI. Practices of the students towards disinfection during performance of certain medical procedures ranged from 10% to 88% of the times showing poor practices of the medical students in following disinfection practices. Conclusion: In the present study the knowledge of medical students for the most common cause of hospital acquired infection was satisfactory. The overall attitude of the students was satisfactory as the mean score was 8. The practices of the students for the application of disinfection during performance of certain medical procedures were also satisfactory, although time to time training and tutorials of these students can help in increasing their knowledge, attitude and practices.
Healthcare associated infection, alternatively also called “hospital acquired infection” (HAI), or “nosocomial infection” refers to the infection occurring in patients after admission at the hospital for a reason other than that infection; an infection that was neither present nor incubating at the time of admission. This includes infections acquired in the hospital but appearing during hospital stay or after discharge, and also occupational infections among staff of the facility [
Keeping the above aspects in mind, the present study was conducted to delineate the level of knowledge, attitudes, and practices for the use of proper disinfection procedures among the final year undergraduate medical students in a tertiary care hospital and teaching institute. The students regularly attended the in-patient and out-patient clinics along with operation theatres, so assessment of their knowledge, attitudes, and practices for HAI is of crucial importance.
The present study is a cross sectional study that included 80 final years under graduate medical students, regularly attending in-patient and out-patient clinics along with operation theatres. It was conducted at tertiary care hospital and teaching institute after ethical clearance. Selection was done on random basis and identities of participants were decoded. The participants who gave consent were provided with a pre-tested questionnaire that included several questions on knowledge attitude and practices on hospital infection prevention, skin disinfection and hand washing, waste disposal, universal precautions and nosocomial infection. Each of the fields was given a score, the KAP score. The questionnaire was designed such that it included a series of items divided in the following sections: 1) knowledge about the frequency of the HAIs and the disinfection practices; 2) attitudes towards the utility of guidelines/protocols and perception of the risks of acquiring or transmitting HAIs; 3) practices and behaviors with antisepsis/disinfection procedures; and 4) sources most frequently used to receive up-to-date information about disinfection procedures. The series of answers to the knowledge questions about disinfection practices were arranged by asking respondents to indicate their agreement with true or false statements on a three point Likert-type scale (i.e., agrees, uncertain, disagrees), and about the frequency of the HAIs were as “yes” and “no” choices. Responses to all items assessing attitudes evaluated relating level of agreement or disagreement were on a ten-point Likert-type scale ranging from “1” to “10”, meaning “not likely at all” and “very likely” for the two questions on the perceived risk for a HCW to acquire from a patient or to transmit to a patient a HAI and for the question towards the utility of guidelines/protocols for disinfection procedures meaning “not at all” and “very much”. Responses to all items assessing the behaviors evaluated whether or not they perform antisepsis/disinfection procedures in their working activity were as “yes” and “no” choices. All data were added to Microsoft excel sheet and percentages of different responses were analyzed.
80 participants who consented were included in the study. All the participants were final year MBBS undergraduate students who regularly attended the in-patient and out-patient clinics along with operation theatres as a part of their clinical teaching curriculum. In the present study, participants had good knowledge and attitude but poor practices towards different aspects of hospital acquired infections and its control measures.
75% (60 participants) of the study population had correct knowledge about the most common HAIs being infection of venous access, urinary tract infection, respiratory infections and surgical site infections, based on their current knowledge on hospital acquired infections as shown in

during certain medical procedures like while taking a biopsy, blood culture collection or during an intra-arterial injection. However the significant difference in the answers might be due to the fact that the study population in majority had final year MBBS undergraduate students who might not have performed/attended such above mentioned procedures. Analysis of Knowledge, Attitudes and practices are shown in
Health care-associated infections have long been recognized as crucial factors undermining the quality and outcomes of health care delivery. Developing
countries were reported to have up to 20 times the risk of contracting a nosocomial infection compared to developed countries. Thus, spread of infection serves as a major source of worry for managers in health care practice, particularly in developing countries where the health care system is already overstretched [
Although infection is most prevalent in patients upon admission, health care workers also act as potential vectors for pathogenic agents. Hospitals provide a favorable transmission pathway for the spread of nosocomial infections, owing partly to poor infection control practices among health workers on one hand and overcrowding of patients in most clinical settings on the other.
In the present study, participants had good knowledge and attitude but poor practices towards different aspects of hospital acquired infections and its control measures. 75% of the participants stated that the infection of venous access, urinary & respiratory tract infections and infection of surgical site as the most common HAIs based on their current knowledge. Attitude towards the utility of guidelines/protocols for disinfection procedures was measured on a ten-point Likert scale ranging from 1 to 10 with higher scores indicating more positive attitudes. The overall attitude of the students was satisfactory as >90% agreed for risk of getting or transmitting any infectious disease by a HCW while working and the utility of the application of disinfection procedures during work would reduce the rates of HAI. The practices of the students for the application of disinfection during performance of certain medical procedures were unsatisfactory. The practice of disinfection was inadequately followed during certain procedures like intra-arterial injections, biopsy, blood culture collection, etc. The reason behind this might be that the students were undergraduate final year medical students so they might not have attended or been able to do such procedures more frequently.
Information regarding to the newer/changing guidelines for infection control practices was given to the medical students by either their colleagues or other medical journals. <50% participants had attended any educational course for disinfection during the past one year. So it would be better if there are regular workshops/seminars for the learning of newer guidelines as these undergraduate students are the future of clinical practice that need to be kept updated for their infection control practices.
Few studies have reported on medical student’s knowledge of standard precautions or sharp injuries [
As the study population contained majority of under graduate final year medical students, they lacked the practice of performing certain procedures like intra arterial injection, biopsy, blood culture collection, etc. Also if other health care workers like resident doctors or nursing staff would have been included in the study, it would have given more informative results as these HCWs are the ones who are in constant contact with the patients.
