Infections like Human Immunodeficiency type 1 and 2 (HIV-1/2), Hepatitis B virus (HBV), and hepatitis C virus (HCV) pose risks to other patients and health care providers during perioperative care. These infections can be and are exposed to the risk of potential infection. Although it is known that precautions prevent exposure, the care of such patients has remained an extra concern to date. Over the last two decades, both the National Institute for transmitted through body fluids and Health and Clinical Excellence (NICE) and the anesthesiologists, surgeons and other health care providers involved in perioperative care frequently comes in contact with such fluids, American Society of Anesthesiologists (ASA) has come out with evidence-based guidelines for the preoperative laboratory tests have been formulated ( 1 , 2 ). The NICE guideline had also been updated recently in 2016. However, there is no recommendation on mandatory screening or routine testing for viral serology in patients who undergo various surgeries or procedures. The Centre for Disease Control and Prevention (United States), recommend every case to be considered as a potential positive case ( 3 ). In India, this issue is neither covered categorically by any administrative/public health guideline, nor by health insurance policies. These facts lead to a dilemma in the context of preoperative routine viral screening, and routine preoperative viral screening/testing is very much prevalent in practice ( 4 ). The present analysis was conducted to evaluate the relationship between workplace and experience of anesthesiologists and surgeons and ordering routine preoperative viral serological testing.

A total of 190 (164 from Anesthesiologists and 26 from the surgeon) responses were eligible for the analysis.One-hundred sixty-nine (88.9%) of the responders were practicing preoperative viral testing routinely; 5.3% did not want to do but had to do due to institutional protocol, and only 5.8% were not doing the tests. While 10 (6.1%) out of 164 anesthesiologists agreed that they do not want the tests to be done but we're doing the tests as per institute protocol; none of the 26 surgeons expressed so (P 0.362, odds ratio 3.6 with 95% confidence 0.20 – 63.37). Among the anesthesiologists who did not want but were doing due to protocol; 40% were from autonomous institutes, and 60% were from teaching backgrounds (from teaching hospitals, colleges, and institutes). Overall, the difference between the surgeon and anesthesiologists in the practice pattern was also not significant, P 0.661. Even the autonomous institutes had a practice of doing the tests in 80% of the time when tests done due to institute protocol were deducted. The test rate was highest in the low experience group (91.1% in the <5 years). The practice pattern of the workplace, location, and experience-wise groups are presented in table 1. Workplace, location, and experience-wise, the practice pattern of anesthesiologists and surgeons were also similar (table 2). The analysis of the total tests done (including the tests done due to protocol) and not done concerning workplace and location, taking autonomous institute and metro city as reference respectively; no statistical difference was noted (table 3). Similar results were also noted in context to experience; total tests done/not done were indifferent in the lower experienced group as compared to the experience of more than10 years (table 4). However, tests done due to protocol (otherwise was not in favor of doing the tests) were significantly lower in government medical colleges (p=0.03) and corporate teaching hospitals (p=0.04) as compared to autonomous institutes (Table 4).

The present analysis showed that the practices of ordering preoperative viral screening tests are very much prevalent in all types of hospitals and across all participants with all levels of experience. Nearly 90% of the participants of any category were practicing it, and this rate is higher than a study conducted by Weber et al ( 5 ). They analyzed data of 15,482 adult patients and found that the screening rate was 65%. However, the study also found that the incidence of newly detected infections was low and concluded with a strong argument in favor of omitting routine preoperative screening ( 5 ). The argument in favor of doing such tests is also prevalent despite the lower prevalence of infection. A study reporting hepatitis C sero prevalence as 2.11%(95%CI;1.1-5.21) argued that by offering routine screening to patients, surgeons have an opportunity to maintain intraoperativesafety( 6 ). However, the argument cannot be accepted as a ground for universal screening as the CDC clearly states that every patient should be taken as a potential positive case and due precautions to be taken ( 3 ). The statement of the American College of Surgeons regarding the surgeon and hepatitis and HIV type 1 and 2 also emphasizes on the highest standard of infection control and advises to use the effective sterile barriers, universal precautions, or all bloodborne pathogens ( 7 , 8 ). Thir statement also emphasizes on immunization against HBV for the surgeon for the prevention of infection from patient to surgeons.

Criticisms of the universal screening are not only limited to the cost and universal precaution, but also due to the window period negativity fact ( 9 ). Advise to screen for hepatitis and HIV has been given based on the resources available from universal screening in high-resource setups to no screening in poor resource setups. The present study analyses the variation of screening or preoperative viral testing in context to the workplace, location, and experience. Usually, the autonomous institutes and big hospitals of metro cities are high resource setups while the semi-urban place hospitals are resource-poor setups. However, the present study findings suggest that there was no difference in the practice of preoperative viral testing in context to the workplace and location. The present study also found that the experience of the health care provider also did not affect the practice of preoperative viral screening. The striking finding was that nearly 90% of the practitioners were advising the tests.

Among Hepatitis B, Hepatitis C, and HIV-1/2, Hepatitis C bears extra importance as it has the highest incidence of transmission after body-fluid contact. The WHO recommended that HCV serology testing be offered to individuals who are part of a population with high HCV prevalence or who have a history of HCV risk exposure/behavior ( 10 ).

Resource consideration is also emphasized by the WHO. The 2014 Guidelines Development Group agreed that the infrastructure for both screening and treatment is necessary for screening to have an impact on key outcomes. Therefore, only screening is not the answer, especially in a country whose per capita health expenditure is minimal.

The present survey is very much limited with a lower number of responses and a national level survey will be required with a larger sample size for a more comprehensible view, especially for the influence of the workplace.

To conclude, this mini-survey indicates that routine preoperative viral screening is frequent and practiced equally by anesthesiologists and surgeons working across different health care setups and having different experiences.
