Bloodborne viral infections: Seroprevalence and relevance of preoperative screening in Indian eye care system - A retrospective study

PURPOSE

To report the seroprevalence of bloodborne viral infection (BBVI) in patients undergoing ophthalmic surgeries and assess the utility and feasibility of preoperative screening for BBVI in India's current eye care system.

METHODS

This retrospective, hospital-based, descriptive study included data from patients undergoing preoperative screening for Hepatitis B virus (HBV), Hepatitis C virus (HCV), and human immunodeficiency virus (HIV) at a tertiary eye care institute from 2018 to 2022. Rapid diagnostic tests (RDTs) were performed on the blood samples after obtaining informed consent from the patients. Seroreactive patients underwent surgery with additional safety precautions. The demographic data and surgical details of these patients were collected and analyzed. ANOVA was used to carry out statistical analysis between groups. During the study period, the number of healthcare workers (HCWs) sustaining needle stick injury (NSI) and accidental sharp injury (ASI) in the operating theater (OT) and details of these injuries were recorded.

RESULTS

Samples from 28,563 patients were included. The seroprevalence of BBVI was 1.87% (536/28563). Hepatitis B virus (322, 60.1%) was the most commonly detected infection, and HIV (59, 11%) was the least detected infection. The mean age of the seroreactive patients was 60.3 ± 30.8 years. The incidence of NSI was 0.49/1000 surgeries. Nurses (11) and technicians (4) in the OT sustained maximum NSI. None of the HCWs had seroconversion after NSI.

CONCLUSION

The overall seroprevalence of BBVI in the current study is lower than that reported in previously published studies from eye care organizations. Currently, mandatory preoperative screening for BBVI to prevent transmission of these infections to HCWs working in the eye care sector in India appears to be less cost-effective.

Sharps and needlestick injuries within the operating room: Risk prone procedures and prevalence meta-analysis

BACKGROUND

Sharps and needlestick injuries pose a serious risk to operating theatre personnel with considerable morbidity, mortality and healthcare implications. The cost of prophylaxis and post-exposure treatment is a significant institutional economic burden.

AIM

The aim of the review was to identify the prevalence of sharps and needlestick injury within the operating theatre and to establish the most common critical steps.

METHOD

A systematic literature search was conducted. Abstracts of all studies published in English from 2015 onwards exploring sharps and needlestick injury within the operating theatre were reviewed. Primary outcome measure was sharps and needlestick injury prevalence. Secondary outcome measures included operational steps resulting in sharps and needlestick injury and costs of sharps and needlestick injury management.

RESULTS

Sixteen studies were identified and included in analysis. Cross-sectional studies reported a pooled prevalence of 41.5% (n = 537; 95% confidence interval = 15.961 to 70.220). Retrospective data analysis reported an annualised prevalence of 5.027% (95% confidence interval = 0.676 to 13.073) on a total pooled sample population of 12,929. Further analysis of operational steps identified a 22% prevalence (n= 3460; 95% confidence interval = 14.2 to 31.3) of sharps and needlestick injury occurring during a procedure involving handing or receiving an instrument.

CONCLUSION

Sharps and needlestick injuries are a significant but preventable risk in the operating theatre. Further research into the development of safety devices to reduce injury during instrument transfer is paramount.

Assessment of Hepatitis B, Hepatitis C and Human Immunodeficiency Virus Screening Results Performed Before Elective Eye Surgery

Objective: Although preoperative screening for Hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infections in patients is a controversial issue in terms of cost-effectiveness and patient privacy, this practice is commonly carried on by surgical branches. The goals of this study were to evaluate the prevalence of preoperative HBV surface antigen (HBsAg), anti-HCV and anti-HIV antibodies, as well as whether seropositive patients were referred to the infectious diseases outpatient clinic. Methods: In this study, blood samples from 884 patients who underwent elective eye surgery at Tokat Gaziosmanpasa University Medical Faculty Hospital between August 2019 and April 2021 were researched for HBsAg, anti-HCV and anti-HIV positivity and seroprevalences were determined. It was also determined whether patients with seropositivity from the hospital automation system had previously been diagnosed and if newly diagnosed patients applied to the infectious diseases outpatient clinic in the subsequent period. Results: The study comprised a total of 884 patients. Males comprised 457 (51.7%) of all patients, with a mean age of 63.21± 16.05. In 29/839 (3.3%) of the patients, HBsAg was positive. Anti-HCV positivity was found in 21/872 (2.4%) people. Anti-HIV positivity was not detected in any of the patients. Conclusion: It would be a more accurate and effective approach to increase compliance with standard hygiene and protection measures rather than requesting routine pre-operative testing for HBV, HCV and HIV. If these tests reveal seropositivity, the patient should be informed of the disease and referred to an infectious disease specialist.

Human immunodeficiency virus and intraocular inflammation in the era of highly active anti retroviral therapy - An update

Intraocular inflammation in patients with human immunodeficiency virus (HIV) infection is commonly due to infectious uveitis. Ocular lesions due to opportunistic infections (OI) are the most common and have been described extensively in the pre highly active antiretroviral therapy (HAART) era. Many eye lesions were classified as acquired immunodeficiency syndrome (AIDS) defining illnesses. HAART-associated improvement in immunity of the individual has changed the pattern of incidence of these hitherto reported known lesions leading to a marked reduction in the occurrence of ocular OI. Newer ocular lesions and newer ocular manifestations of known agents have been noted. Immune recovery uveitis (IRU), the new menace, which occurs as part of immune recovery inflammatory syndrome (IRIS) in the eye, can present with significant ocular inflammation and can pose a diagnostic and therapeutic challenge. Balancing the treatment of inflammation with the risk of reactivation of OI is a task by itself. Ocular involvement in the HAART era can be due to the adverse effects of some systemic drugs used in the management of HIV/AIDS. Drug-associated retinal toxicity and other ocular side effects are being increasingly reported. In this review, we discuss the ocular manifestations in HIV patients and its varied presentations following the introduction of HAART, drug-associated lesions, and the current treatment guidelines.
