  Abstract 


Introduction: Hand hygiene play crucial role in infectious control. The present research is on accessing Knowledge, attitude, and practice of nursing staff regarding hand washing. Human hands are covered with several commensal and pathogenic microorganism. Pathogenic bacterial species especially Staphylococcus species are the most common to participate in nosocomial infections. Methods: Total 300 hand swab samples were taken from 150 nursing staffs followed by filling the questionnaire form. Standard culture media (Blood agar and MacConkey agar) were used to isolate the microorganisms. Microbial identification was done by using standard biochemical tests. Results: Our study concluded that over all staff members had moderate knowledge and attitude regarding hand washing. Coagulase-negative Staphylococcus isolates were the most dominant bacteria. Occurrence of Staphylococcus aureus was relatively less. Conclusions: Creating awareness and education regarding hand hygiene would definitely increase the attitude and practice of health care workers to minimizing the nosocomial infection.

Keywords: Hand hygiene, hand microflora, nosocomial infection, nursing staff, Staphylococcus aureus

  Introduction Top


Adequate infection control practice is one of the key elements for restricting the spread of healthcare-associated infectious-disease. A numerous guidelines state that handwashing is the most essential procedure to prevent nosocomial infection but on the parallel hand many studies continue to report unacceptable health-care worker hand-hygiene compliance rates. Minimal sustained success has been outlined even after countless efforts to improve hand-hygiene behavior that focused on broad-based educational and motivational programs. Poor hand-hygiene adherence transpires due to unavailability of hand-washing sinks, lack of time to perform hand hygiene, patient's underlying condition, outcomes of hand-hygiene products on the skin, and unawareness of the guidelines.[1],[2] Healthcare syndicated infections are voluminously listed as a consequence of person-to-person transmission of nosocomial pathogens via the hands of healthcare personnel. It is also evident that the rise in levels of micro-organisms contamination has been identified due to flawed nursing practices, such as direct touching, contact with bodily fluids, and wound care. Even during relatively clean procedures, such as taking the pulse, measuring arterial blood pressure and checking temperature, nurses hands can become open to bacteria. The hand-washing habits of nurses are debatable for many reasons, which include the cumbersome structure of intensive care units, the characteristics of the patients in intensive care, the heavy workload in such units, and an insufficiency of nurses.[3],[4] Undeniably, with varied environmental factors and host factors, human skin is known to be immutably covered with microorganisms, both commensals and pathogens depending on topography. Either hospital surroundings or poor hygiene is one of the key factors of transient micro-flora on the hand which is dynamically responsible for cross-infections. The common organisms associated are Staphylococcus aureus, Coagulase negative Staphylococcus species, Klebsiella species, Pseudomonas species, Acinetobacter species, or any other pathogen which is present in the environment of a healthcare facility.[5],[6] Keeping this in view, the present study was done with two main objectives to access hand hygiene practices:

  1. Evaluation of Hand-washing knowledge, attitude and practice among the nursing staff dealing with patients.
  2. Analysis of Hand Micro flora of nursing staff.



  Material and Methods Top


This prospective-study was done in Microbiology Department of Maharishi Markandeshwar Medical College and Hospital, Solan with prior Ethical clearance (MMU/IEC/P. No. 13/17) 09/03/2017. Total 150 nursing staff's hand swabs were taken with informed consent. Sterile swabs were used for taking the samples. Two hand swabs (Palm) were taken from each health care workers followed by filling the questionnaire form which was having questions about hand hygiene. Swabs were cultured on 5%-Blood agar and MacConkey agar. Bacterial colonies on culture media were identified by using standard biochemical tests. Gram stain; 3%-catalase test; oxidase test; triple-sugar-iron agar; nitrate reduction test; urease-production test; IMViC tests and sugar fermentation tests were used for identification of gram-negative bacteria. Gram stain; 3%-catalase test; slide/tube-coagulase test; mannitol fermentation test and DNase test were used for identification of gram positive bacteria followed by screening of MRSA (Methicillin resistant Staphylococcus aureus) by Cefoxitin (30 μg) disk diffusion method and antibiotic susceptibility pattern of Staphylococcus aureus by using antibiotics: Trimethoprim/Sulfamethoxazole (1.25/23.75 μg), Ciprofloxacin (5 μg), Erythromycin (15 μg), Clindamycin (2 μg), Linezolid (30 μg).[6],[7],[8]

Questionnaire regarding general information revealed that 84% staff nurses said to have adequate facilities for hand washing in their working area. About 90% staff had good knowledge about the importance of hand hygiene in nosocomial infections. About 52% staff believed that regular hand washing with soap do not decrease the bacterial load of the hands. Moreover, 59% staff members assumed that wearing hand gloves could be the replacement for hand washing. Majority staff nurses (84%) knew importance of handwashing with antiseptic soap. Almost all staff members (99%) were aware about 7 steps of hand washing [Table 3].

Attitude-based questions were asked to staff members in which less members (14%) felt irritated after repeated hand washing. 14% of the staff tend to forget washing their hands while dealing with patients as 54% of staff workers thought emergencies and other priorities make hand washing more difficult to perform. Maximum number of health care workers (80%) always ensured correct hand washing at all the times. 96% staff felt disappointed when their colleagues omitted the hand hygiene [Table 4].

While asking practice-based questions, majority staff (71%) had habit of washing their hands before wearing gloves. Most of the staff members (86%) said that they always ensured effective hand washing by using antiseptic soap followed by alcohol-based hand-sanitizer. Half of the members (51%) admitted to follow proper 7 steps of hand washing. 50% staff members preferred alcohol-based hand rub over antiseptic soap on unsoiled hands. 71% of the health care workers had not given instructions about the hand hygiene during their training and orientation classes. We found that only 48% staff were maintaining hand hygiene before and after physically handling of the patients. 61% of them said that infection prevention team and their activities do not remind them to maintain hand hygiene [Table 5].

Out of 300 swabs collected from the hands of 150 nurses working in critical areas, 285 hand swabs showed the growth. Almost all the swab showed growth of more than 2 organisms on culture media. Out of 531 isolates 39 (7.34%) isolates were Staphylococcus aureus and 44% of them were found to be Methicillin resistant (MRSA) based on the Cefoxitin resistance as per CLSI guidelines. The major Gram-Positive pathogenic organisms seen were Coagulase negative Staphylococcus species 190 (35.78%) followed by Micrococcus (17.32%) whereas amongst Gram Negative bacteria Acinetobacter species (11.29%) and Other Non-fermenters (1.12%) were predominant. Few of the Candida species 12 (2.25%) were also isolated [Table 6].

The antimicrobial susceptibility pattern of S. aureus isolates varies widely by region because it depends on antibiotic exposure to that particular population. In the context of antibiotic susceptibility pattern in our study, Linezolid (100%) was found to be highly active followed by Clindamycin (50%) whereas Trimethoprim/Sulfamethoxazole was found to be least sensitive against Staphylococcus aureus [Table 7].

  Discussion Top


Most important and basic practice to minimize the health care associated infections in primary care is maintaining the proper Hand hygiene by the primary care physicians. Implementation of hand washing technique on the regular basis in primary care physicians is contributing in lowering the morbidity and mortality.[9] Present study found out that over all nursing staff members had moderate knowledge, attitude, and practice regarding hand hygiene, similar finding were too reported by other researchers.[10],[11] Our study population was relatively younger compared to other studies[12],[13] as 80% of staff members belonged to age group of 20–25 years. Occurrence of healthcare-associated-infections decreased after strict implementation of hand-hygiene.[14] Studied conducted in hospitals revealed that healthcare staff was frequently using antiseptics ranged from 30-100 times per shift which was quite high compared to our study where staff was using antiseptics 1–4 times per shift.[15],[16] Present study showed that attitude of staff was quite good regarding hand washing. When we assessed for hand hygiene practices, we found that majority of staff were not doing better practices. Whereas a study done by MHJD Ariyaratne et al. revealed that only 5.53% workers were performing good practices.[10] The attitude regarding correct hand hygiene practices should be followed at all times, proper training and orientation infection control programs for improvement of hand hygiene can improve overall attitude of health care staff.[17]

Out of 300 swabs, 15 swabs (5%) were culture negative as staff had recent hand washing history and it was comparable to a study done by Fahriye Eksi et al.[18] CONS were the most predominant isolate among all isolates accounting for 35.78%. On other hand Mathavi Sureshkumar et al.[19] reported Diphtheroids (47%) as most dominant isolate. In our study occurrence of Staphylococcus aureus (7.34%) were less compared to other studies as Veena Maheshwari et al.[17] reported 36.14% and Asim Sarfraz et al.[20]reported 33% occurrence of Staphylococcus aureus out of all isolates. Our study revealed that 44% strains of S. aureus were MRSA, almost same result was documented by R Kapil et al.[21] with 45% occurrence of MRSA. In contrast to present finding, Ranweer et al.[22] reported the lower occurrence of MRSA (7%). Linezolid (100%) was found to be most effective antibiotic among all tested, Veena Maheshwari et al.[17] and Williams JV et al.[23] also stated the same results whereas other antibiotics were showing little higher resistance. Growth from Enterobacteriaceae family found to be very less in our study.


  Conclusion Top


Nursing staff is one of important domain of primary care physicians as they play crucial role in infection control. Our study concluded that knowledge, attitude, and practice about hand washing in our nursing staff were found to be moderate. Load of Staphylococcus aureus was comparatively less on staff's hand as staffs were following adequate hand hygiene practices. It was very important to know the current status about hand hygiene so that we can overcome those deficiencies by conducting more training programs regarding improvement of hand hygiene. Continuous teaching and monitoring of staff regarding hand hygiene practices will encourage them to follow correct hand hygiene practices.
