Introduction
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 [1] [2] [3]. As a general timeline, infections occurring more than 48 hours after admission are usually considered hospital acquired. The Hospital Infection Society of India (HISI) finds the latter justified in the Indian scenario, as most of the time it is difficult to make out whether an infection was acquired outside the hospital or inside a specific healthcare set-up [4]. 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 [1] [2] [5]. Moreover, the burden of HAIs is higher in developing countries [6]. In 2007, the INICC conducted a prospective surveillance in 7 Indian cities to determine the rate of HAI. An overall HAI incidence rate of 4.4% corresponding to 9.06 infections per 1000 ICU-days was reported [7]. Lately, there are increasing reports from different parts of the country revealing varying HAI incidence rates across various healthcare setups.
HAIs account for major causes of death, functional disability, emotional suffering and economic burden among the hospitalized patients [2] [3]. The increased length of stay for infected patients is the greatest contributor to cost. The increased use of drugs, the need for isolation, and the use of additional laboratory and other diagnostic studies also contribute to costs. In India, the extravagant use of antibiotics and antibiotic resistance adds to the expenditure as well as mortality following HAI [8]. Additionally, in India, infections due to multi drug resistant International Journal of Clinical Medicine organisms increase mortality and also warrant the use of high end antibiotics like Carbapenems and new generation Tetracyclines which increase the health care expenditure [3].
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.

Material and Method
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.  Table 1. Also about 94% of the participants correctly knew 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.

Result
The percentage of the respondents who had appropriate knowledge on the questions of most common HAIs and inappropriate disinfection causing HAI is shown in Table 1.
Attitudes towards the utility of guidelines/protocols for disinfection procedures, measured on a ten-point Likert scale ranging from 1 to 10 with higher scores indicating more positive attitudes as shown in Table 2. Responses from the study participants showed a mean score of 7 with the highest score being 9 and the lowest being 4. >90% participants had a good attitude towards 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.
Practices of the students towards disinfection during performance of certain medical procedures ranged from 10% to 88% of the times ( Table 3). >80% of the participants practiced disinfection procedures during certain medical procedures like insertion venous catheter, urethral catheter and intramuscular or intravenous injections. <50% answered that they followed disinfection procedures      Figure 2 shows that KAP analysis of students revels that attitude towards infection control practices found well but because lack of knowledge, people are not able to perform right practices. Regular trainings and efforts to increase knowledge may work for control of health care associated infections.

Discussion
Health care-associated infections have long been recognized as crucial factors undermining the quality and outcomes of health care delivery. Developing International Journal of Clinical Medicine   Few studies have reported on medical student's knowledge of standard precautions or sharp injuries [9] [10] [11] and noted a lack of adequate knowledge of standard precautions [11]. In one survey, 27% of participating health care students reported insufficient emphasis on teaching about infection control in their training program, whilst 50% expressed a desire for more emphasis on isolation procedures during their training [12]. Certain other studies [13] [14] have detected poor adherence to universal precautions among multiple health care providers. In a study by, it was found the general medical practitioners and medical college students had sufficient knowledge and attitude towards nosocomial infections. Also both these groups practice approach towards nosocomial infection was not sufficient and it needs improvement [15].

Limitation
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.
