Microbial Organisms

The main objective of the study was to find out the contamination of different types of microbial organisms and their resistance pattern on the dresses and stethoscopes of the health care workers in order to evaluate the risk of transmission of microbial organisms and its consequences on safety of the patient and control of hospital acquired infections (HAIs). Swabs were taken from the dresses of 100 different healthcare workers from 4 different areas namely collar, pocket, sleeves and sides and 100 stethoscopes (diaphragm) were tested for bacteriological analysis using standard techniques. Then each health care worker were given a structured questionnaire and requested to fill the form which includes his or her speciality/unit, cadre, practice of hand hygiene, white-coat or uniform usage (Example: duration of usage, frequency of washing, type of washing etc). The collar and pockets were found to be the most contaminated areas. Gram-positive cocci such as Staphylococcus aureus and Coagulase-negative Staphylococci (CONS) were the important organisms isolated from the dresses and stethoscopes of health care workers followed by Gram-negative bacilli such as Pseudomonas aeruginosa and Klebsiella species. Among the microbial organisms, Staphylococcus aureus and CONS were resistant to the drugs like Co-trimoxazole and Penicillin-G. Organisms isolated from the dresses and stethoscopes of health care workers could be a source of infection to immunocompromised patients. Hence, frequent washing of the dresses and strict disinfectant practices of the stethoscopes will minimize the contamination with microbial organisms and the patient safety is improved in the hospital environment.

Background: The presence of Staphylococcus aureus in anterior nares of health care workers may serve as a major source of infection in hospital environment and act as a reservoir for the spread of Methicillin Resistant S. aureus between patients.Objective: The present study was conducted to determine the frequency of nasal carriage of S. aureus among the health care workers of Kathmandu Medical College Teaching Hospital and to assess the antibioticsusceptibility patterns of the Methicillin Resistant S. aureus isolates.Methodology: A total of 200 health care workers involved in the management of patients from the intensive care unit, Operation Theatre, postoperative wards, different wards and emergency department were screened for S. aureus by collecting their nasal swabs.Results: Out of 200 health care workers, only 10(5%) were S. aureus nasal carriers. Out of 10 S. aureus strains isolated six (60%) were methicillin sensitive S. aureuswhereas four (40%) were methicillin resistant S. aureus. The isolates were 100% sensitive to Linezolid, Vancomycin and Amikacin but showed highest resistant to Azithromycin (100%), followed by Cefixime (60%).Conclusion: This study concluded that 5% of health care workers were S. aureus carriers and proportion of Methicillin Resistant S. aureus and Methicillin sensitive S. aureus was 60% and 40% respectively.Journal of Kathmandu Medical CollegeVol. 7, No. 2, Issue 24, Apr.-Jun., 2018, page: 64-67

Background: The extensive use of mobile phones in the hospital among health care workers (HCWs) can lead to infectious agents being transferred from one patient to another and thus serve as a vehicle in the transmission of nosocomial pathogens. Objectives: This study aimed to investigate the prevalence of Methicillin Resistant Staphylococcus auerus (MRSA) contamination of mobile phones and hands of HCWs in Gandaki Medical College and Teaching Hospital. Methods: The present study was hospital and laboratory based cross-sectional study, carried out from April, 2017 to December, 2017. A total of 100 mobile phone swab and 100 hand swab samples of HCWs were collected and cultured directly on MacConkey agar, blood agar, and mannitol salt agar after 24 hrs of enrichment. All the isolated organisms including MRSA were identified using standard microbiological techniques and subjected to antibiotic susceptibility testing using disc diffusion technique. Results: Among the Gram positive isolates, frequency distribution from mobile phones showed the highest prevalence of coagulase negative Staphylococci (CONS) (34.69%), followed by Staphylococcus aureus (20.41%), Bacillus spp (15.31%), Micrococci spp (11.23%), however considerable number of Diptheroides (8.16%), Enterococci (6.12%) and Streptococcus pneumoniae (4.08%). Siimilarly from hand swabs CONS (39.62%), followed by S. aureus (26.42%), Bacillus spp (10.38%), Micrococci (11.32%), Enterococci (6.60%) and Diptheroids (5.66%) were isolated. The frequency of MRSA was 20%, 25% among mobile phones and hands of HCWs respectively. Drugs like Vancomycin, Amikacin, Clindamycin and Gentamycin were found quite effective against S. aureus in the present study and would be better options for the management of such infections. Conclusions: Mobile phones and hands of HCWs were the potential source of nosocomial infections including multidrug-resistant pathogens like methicillin-resistant S. aureus.

Staphylococcus aureus and Streptococcus pyogenes are two highly infectious pathogens implicated in a significant percentage of healthcare associated infections. They produce wide range of infections, from mere folliculitis & furuncles, cellulitis, myositis, & glomerulonephritis to conditions with very significant morbidity such as necrotizing fasciitis & Toxic Shock syndrome, and thus represent an important subset of infections that need to be tackled urgently. To assess prevalence of nasal as well as oropharyngeal carriage of Staphylococcus aureus & Streptococcus pyogenes among health-care workers and its antimicrobial resistance pattern. One nasal swab & two oropharyngeal swabs were collected from each participant, with one nasal & oropharyngeal swab cultured on blood agar & mannitol salt agar for Staphylococcus aureus, and the second oropharyngeal swabs were cultured on Crystal violet blood agar for Streptococcus pyogenes, further subjected to susceptibility test by disc diffusion method on Muller-Hinton agar as per CLSI guidelines 2019. Prevalence of Staphylococcus aureus carriage was 9% which includes 4% It is nasal, 4.5% oropharyngeal & 0.5% both. Prevalence of MRSA, MLSB & mupirocin resistant Staphylococcus aureus was 1.5%,4% & 0%respectively. Prevalence of oropharyngeal carriage of Streptococcus pyogenes was 1.5%. This study feature the need of screening of Health-care workers for nasal as well as oropharyngeal carriage of Staphylococcus aureus & Streptococcus pyogenes & further its antimicrobial resistance pattern.

Hygiene Measures

Background: Iatrogenic and nosocomial infections are a serious threat to a healthcare setting especially during a pandemic. Hand hygiene among the health-care workers stands out to be a pivotal preventive measure. Practical application of hand hygiene measures during third wave of COVID-19 pandemic primarily depend upon the current knowledge among the health care workers. Methods: A cross-sectional study design based on validated WHO questionnaire for hand hygiene among the health care workers was conducted during March till May2021 in the settings of Shalamar and Central Park hospital and medical colleges. Results: The sample consisted of 271 participants with 110 males and 161 females, with the mean age of 24.72+ 4.174 years. The sample consisted of 36.2% of medical students, 49.1% of doctors and 14.8% of paramedical staff. Nearly 50.6% of the individuals claim to receive formal training. 47.6% believe that “Health-care workers’ hands when not clean” are the main route of cross-transmission. Nearly 57.2% believed that the hospital environment (surfaces)the most frequent source of germs. Comparison of hand-rubbing and washing revealed that major percentage believe hand rub to be rapid however less effective causing dryness. A majority believe that hand hygiene before touching the patient, immediately after exposure to body fluids or immediate surroundings of patients prevents transmission of germs to the patient and vice versa afterwards prevents transmission to HCW. Conclusion: A large proportion of the sample has considerable knowledge regarding essential hand hygiene in a health care setting. However more frequent training sessions should be conducted to improve it further. Key words: Hand hygiene, Health-care workers, Knowledge
