Hepatitis B vaccination in correctional health care workers

Preventing hepatitis B virus infection among healthcare professionals: potential impact of a 2-dose versus 3-dose vaccine

The exposure risk to the highly infectious hepatitis B virus (HBV) is an established and recognizable hazard to healthcare professionals (HCPs). In the United States, implementing preemptive vaccination programs and safety procedures resulted in drastic reductions in HBV infections among HCPs; however, many HCPs remain unprotected and risk of exposure persists, especially among those first entering a healthcare system and undergoing professional training. First-generation HBV vaccines require completion of a 3-dose schedule over a 6-month interval for maximum immunogenicity. By comparison, HepB-CpG (HEPLISAV-B®) is a 2-dose HBV vaccine licensed in the United States in 2017, inducing rapid seroprotection over a 1-month interval and may represent a more effective strategy for combating HBV infection in US healthcare systems. In this modeling study, the health and economic impact of implementing an HBV vaccination strategy with HepB-CpG versus the 3-dose HBV vaccine (Engerix-B®) was evaluated among HCPs newly entering a healthcare system. The model used effective seroprotection rate, a real-world metric accounting for HCP vaccine compliance and seroprotection rates for different dosing regimens and considered current pricing for postexposure prophylaxis treatment. Compared with the 3-dose vaccine, HepB-CpG was anticipated to provide faster, increased protection against HBV infection among newly entered HCPs. In protecting a greater percentage of HCPs, HepB-CpG was also projected to substantially reduce the risk of HBV exposure. Accordingly, an economic analysis showed HepB-CpG vaccination would reduce costs of postexposure prophylaxis treatment compared with the 3-dose vaccine. Overall, HepB-CpG represents an effective therapeutic strategy against HBV infection for US healthcare systems.

Nursing Assistants' Use of Personal Protective Equipment Regarding Contact With Excreta Contaminated With Antineoplastic Drugs

PURPOSE

To examine the feasibility of observing and interviewing nursing assistants about handling of antineoplastic drugs contaminated with excreta, acceptability of a measure of personal protective equipment (PPE) use with nursing assistants, and predictors of PPE use.

PARTICIPANTS & SETTING

27 nursing assistants in an inpatient hematology-oncology unit at an academic medical center in the southeastern United States.

METHODOLOGIC APPROACH

This was an exploratory, multimethod study using observation, verbally administered questionnaires, and interviews. Research variables included recruitment rates, acceptability of observation, and understandability of a safe-handling instrument.

FINDINGS

Observed use of double gloves, chemotherapy gowns, and face shields was low; use of plastic-backed pads when flushing excreta was high.

IMPLICATIONS FOR NURSING

Nursing assistants are willing to participate in research. Standardized training and education about PPE use are needed.

Safety Risks Among Home Infusion Nurses and Other Home Health Care Providers

In the United States, home health care (HHC) is a rapidly growing industry and home infusion therapy is a rapidly growing market. HHC can present substantial occupational safety and health (OSH) risks. This article summarizes major OSH risks relevant to home infusion therapy by illustrating them through real-life scenarios collected systematically using qualitative research methods by the National Institute for Occupational Safety and Health-funded research projects at the University of Massachusetts Lowell. The need for home infusion therapy will continue to grow in the future, and safety interventions to prevent or minimize OSH risks are essential.

Seroprevalence of hepatitis B and C among domestic and healthcare waste handlers in Belo Horizonte, Brazil

Infection with the hepatitis B and C viruses may occur through contact with infected body fluids, including injury with infected sharps. Collectors of domestic or healthcare wastes are potentially exposed to these infections. The aim of this article is to investigate the risk factors associated with the prevalence of hepatitis B and C viruses (HBV and HCV) infection among domestic and healthcare waste workers in Belo Horizonte, Brazil. A cross-sectional study of hepatitis B and C infection was conducted from November 2014 to January 2015, through blood sample collection and interviews about socio-demographic factors with 61 workers exposed to healthcare waste ('exposed') and 461 exposed only to domestic wastes ('unexposed'). The prevalence of antibodies to HCV (Anti-HCV) antibodies was 3.3% in 'exposed' workers and 0.9% in 'unexposed', and of antibody to hepatitis B core antigen (Anti-HBc) was 9.8% and 5.6% in 'exposed' and 'unexposed' workers, respectively. Only 207 (44.9%) of those exposed to domestic waste and 45 (73.8%) of those handling healthcare waste were effectively immunised against hepatitis B virus (HBV). Exposures to domestic waste and to healthcare wastes were associated with similar risks of infection with HBV. The risk of hepatitis C virus (HCV) infection was marginally higher among healthcare waste workers compared with domestic waste workers, probably because of needlestick accidents owing to deficient sharps management systems. Immunisation against hepatitis B and screening tests to ensure the success of vaccination should be a condition for recruitment for both groups of waste workers.

Factors Associated with Needlestick Injuries in Health Care Occupations: A Systematic Review

INTRODUCTION

Needlestick and sharps injuries (NSIs), are among the main job-related injuries that health care workers experience. In fact, contraction of hepatitis B or hepatitis C from work-related NSIs is one of the most common occupational hazards among health care workers.

AIM

The aim of this study was to determine the factors associated with NSIs in health care occupation.

MATERIALS AND METHODS

In this study, a systematic and purposive review with emphasis on the research question was run to retrieve, evaluate and consolidate the required information. The following four key words were used to search for the relevant articles published from January 1998 to May 2015: NSI health care workers, risk factor and factors associated, in Science direct, EBSCO Host, PubMed, ProQuest, SID and Cochrane Library. Several steps of evaluation were taken to select and analyse the full texts of relevant articles. According to the inclusion criteria, we finally selected 11 articles from the 18642 retrieved articles.

RESULTS

The data of the analysed articles indicated that the highest incidence of NSIs was seen in nurses and that the associated factors were age, level of education, number of shifts per month and history of related training. The highest rate of NSIs was related to instrument preparation followed by injection and recapping of used needles. Findings show that health care workers suffer a high rate of needlestick injuries.

CONCLUSION

It was seen that device, location, or action cannot be separately considered as responsible for all types of the NSIs. Rather, each of them has a contribution to the NSIs. Nevertheless, factors with higher frequency should be given a higher priority.

Home Health Care Challenges and Avian Influenza

Recent public health disasters, both nationally and internationally, have underscored the importance of preparedness in effectively responding to these events. Within the home health care sector, preparedness is especially critical, as home care patients may be at increased risk of disaster-related morbidity and mortality because of their age, disability, or other vulnerability. Importantly, the home health care population is growing, with an estimated 7 million patients currently receiving home health care services. Yet the degree of preparedness at all levels of the home care sector (agency, health care worker, and patient and/or family) is largely unknown. Without this knowledge, important first steps toward development and implementation designed to address barriers to preparedness cannot be taken. To help address some of these knowledge gaps, one aspect of preparedness, namely the willingness of home health care workers to respond during an avian influenza outbreak, was recently examined. Findings revealed very low levels of willingness. Preliminary recommendations designed to address this issue are presented following a general discussion of the issue.

Hepatitis B and C in household and health services solid waste workers

Human contact with solid waste poses biological, chemical, and physical health risks for workers involved in waste collection, transportation, and storage. The potential risk to human health resulting from contact with health services waste or household waste still sparks considerable controversy. The aim of this study was to identify the context of scientific discussions on risk/infection from the hepatitis B and C viruses in workers that collect solid waste from health services or households. The search covered publications up to 2013 in Brazilian and international databases, and 11 articles were selected through a literature review. Of these, six conclude that there is an increased risk of infection in workers that collect household waste when compared to those unexposed to waste, three point to greater risk for workers that collect health services waste as compared to those that collect ordinary waste, and the other two found no difference between exposed and unexposed individuals.

Evaluation of an e-learning package to improve understanding of blood-borne viruses amongst prison staff in Wales, UK

PURPOSE

The purpose of this paper is to provide education on blood-borne viruses (BBVs) to prison staff to help reduce stigma within the prisons, improve the care prisoners receive and reduce the risk of occupational transmission.

DESIGN/METHODOLOGY/APPROACH

An e-module was used to improve staff understanding of hepatitis B (HBV), hepatitis C (HCV) and HIV at a prison in Wales, UK. An assessment was used to gather data on prison staff understanding of BBVs prior to undertaking the e-module.

FINDINGS

In total, 530/697 (76 per cent) prison staff completed the BBV e-module. Average pre- and post-course assessment scores were 8.6/11 and 10.85/11, respectively. Most staff understood the modes of hepatitis transmission, however, gaps in understanding were highlighted. In total, 22 per cent of staff believed HBV and HCV were airborne, 9 per cent believed transmission occurred through sharing cutlery. In total, 31 per cent of staff believed prisoners with hepatitis should declare their status to the prison. Practical implications: The e-module significantly improved staff understanding of BBVs and should be incorporated into future prison training packages. Future education should include how BBVs are not transmitted with an emphasis on casual contact. Medical confidentiality in prisons should also be addressed. Improving understanding will help reduce the stigma of BBVs within prison and improve the multidisciplinary care the prisoner receives.

ORIGINALITY/VALUE

To the authors knowledge this is the first published evaluation of a BBV learning package for custodial staff. Evaluation of this educational package demonstrates a unique and valuable insight into the general understanding of BBVs by prison staff in Wales, UK.

Needle stick injuries--risk and preventive factors: a study among health care workers in tertiary care hospitals in Pakistan

BACKGROUND

Health care workers (HCWs) are at substantial risk of acquiring blood borne infections such as HIV, Hepatitis-B and Hepatitis-C through needle stick injuries (NSIs). This study aimed to assess the proportion of NSIs and their associated factors among HCWs and also to identify the areas in which preventive efforts might be directed to protect against this occupational hazard.

METHODOLOGY

A cross-sectional study was conducted in two tertiary care hospitals of Pakistan representing both private and public health sector. A total of 497 HCWs (doctors and nurses) were interviewed using a structured questionnaire. Data was collected from January to May 2008.

RESULTS

Overall, 64% of the HCWs were exposed to at least one NSI during their career; among them 73% reported NSIs for two or more times. Factors found to be highly associated with NSIs were those practicing this occupation for more than five years (p < 0.001: OR = 5.92; 95% CI = 3.45-10.16) and working as nurse than doctor (p 0.001: OR = 2.12; 95% CI = 1.35-3.32). Having received booster dose of hepatitis B vaccine (p 0.02: OR = 1.85; 95% CI = 1.10-3.11), working in surgical specialty (p < 0.01: OR = 1.6; 95% CI = 1.09-2.51) and being a female (p 0.03: OR = 1.52; 95% CI = 1.04-2.22) were also found to be associated with NSIs. Most commonly reported reason for NSIs was injecting medicine and drawing blood (42%) followed by two-handed recapping of needle (37%). Only, 34% of study subjects were vaccinated against hepatitis B infection. Overall, HCWs had inadequate practices regarding standard precautions such as availability of gloves/protective cloths (40%) and infection control guidelines/protocols (10%) respectively in their working places.

CONCLUSION

In addition to very high rates of NSIs, low safety practices including inadequate vaccination coverage, unavailability of infection control guidelines and other preventive facilities were reported in this study. Prevention of occupational infections among HCWs should be a priority. Formal training, by health authorities in the local area, about safe practices and availability of preventive facilities should be ensured regarding NSIs among HCWs.

Factors influencing oncology nurses' use of hazardous drug safe-handling precautions

PURPOSE/OBJECTIVES

To examine relationships among factors affecting nurses' use of hazardous drug (HD) safe-handling precautions, identify factors that promote or interfere with HD precaution use, and determine managers' perspectives on the use of HD safe-handling precautions.

DESIGN

Cross-sectional, mixed methods; mailed survey to nurses who handle chemotherapy and telephone interviews with managers.

SETTING

Mailed invitation to oncology centers across the United States.

SAMPLE

165 nurses who reported handling chemotherapy and 20 managers of nurses handling chemotherapy.

METHODS

Instruments measured the use of HD precautions and individual and organizational factors believed to influence precaution use. Data analysis included descriptive statistics and hierarchical regression. Manager interview data were analyzed using content analysis.

MAIN RESEARCH VARIABLES

Chemotherapy exposure knowledge, self-efficacy, perceived barriers, perceived risk, interpersonal influences, and workplace safety climate.

FINDINGS

Nurses were well educated, experienced, and certified in oncology nursing. The majority worked in outpatient settings and administered chemotherapy to an average of 6.8 patients per day. Exposure knowledge, self-efficacy for using personal protective equipment, and perceived risk of harm from HD exposure were high; total precaution use was low. Nurse characteristics did not predict HD precaution use. Fewer barriers, better workplace safety climate, and fewer patients per day were independent predictors of higher HD precaution use. HD handling policies were present, but many did not reflect current recommendations. Few managers formally monitored nurses' HD precaution use.

CONCLUSIONS

Circumstances in the workplace interfere with nurses' use of HD precautions.

IMPLICATIONS FOR NURSING

Interventions should include fostering a positive workplace safety climate, reducing barriers, and providing appropriate nurse-patient ratios.

Concerns regarding hepatitis B vaccination and post-vaccination test among Brazilian dentists

Background

Hepatitis B infection is the major cause of acute and chronic liver disease, cirrhosis and hepatocellular carcinoma worldwide and has long been recognized as an occupational hazard among dentists. The aim of the present study was to examine factors associated to the self-reporting of hepatitis B vaccination and immunization status among dentists working in the city of Belo Horizonte, Brazil.

Methods

A cross-sectional survey was carried out with 1302 dentists in Belo Horizonte, Brazil. After signing a term of informed consent, the participants answered a structured questionnaire on their knowledge regarding their vaccination and immunization status against hepatitis B. Data on demographic, behavioural and occupational exposure aspects were also collected through questionnaires.

Results

The results revealed that 73.8% of the dentists reported having received three doses of the vaccine. Multivariate analysis revealed that gender (p = 0.006), use of individual protective equipment (p = 0.021), history of blood transfusion (p = 0.024) and history of illicit drug use (p = 0.013) were independently associated with vaccination against hepatitis B. Only 14.8% had performed a post-vaccination test. The use of individual protective equipment (p = 0.038), dentists who asked patients about hepatitis during dental treatment (p < 0.001), a family history of hepatitis B (p = 0.003) and work experience (p < 0.05) were independently associated with the post-vaccination test.

Conclusions

Although there were a large number of vaccinated dentists in Belo Horizonte, the percentage was less than what was expected, as Brazil offers the National Program of Viral Hepatitis Vaccination, which provides free hepatitis B vaccinations to all healthcare workers. Despite being part of a high risk group for contamination, most of the dentists did not know their immunization status.

Non-hospital based registered nurses and the risk of bloodborne pathogen exposure

The aim of this study was to assess the risk of blood and body fluid exposure among non-hospital based registered nurses (RNs) employed in New York State. The study population was mainly unionized public sector workers, employed in state institutions. A self-administered questionnaire was completed by a random stratified sample of members of the New York State Nurses Association and registered nurse members of the New York State Public Employees Federation. Results were reviewed by participatory action research (PAR) teams to identify opportunities for improvement. Nine percent of respondents reported at least one needlestick injury in the 12-month period prior to the study. The percutaneous injury (PI) rate was 13.8 per 100 person years. Under-reporting was common; 49% of all PIs were never formally reported and 70% never received any post-exposure care. Primary reasons for not reporting included: time constraints, fear, and lack of information on reporting. Significant correlates of needlestick injuries included tenure, patient load, hours worked, lack of compliance with standard precautions, handling needles and other sharps, poor safety climate, and inadequate training and availability of safety devices (p<0.05). PAR teams identified several risk reduction strategies, with an emphasis on safety devices. Non-hospital based RNs are at risk for bloodborne exposure at rates comparable to hospital based RNs; underreporting is an important obstacle to infection prevention, and primary and secondary risk management strategies appeared to be poorly implemented. Intervention research is warranted to evaluate improved risk reduction practices tailored to this population of RNs.

There's no place like home: a qualitative study of the working conditions of home health care providers

OBJECTIVE

Home health care (HHC) is one of the fastest growing US industries. Its working conditions have been challenging to evaluate, because the work environments are highly variable and geographically dispersed. This study aims to characterize qualitatively the work experience and hazards of HHC clinicians, with a focus on risk factors for bloodborne pathogen exposures.

METHODS

The researchers conducted five focus group discussions with HHC clinicians and ten in-depth interviews with HHC agency managers and trade union representatives in Massachusetts.

RESULTS

HHC clinicians face serious occupational hazards, including violence in neighborhoods and homes, lack of workstations, heavy patient lifting, improper disposal of dressings or sharp medical devices, and high productivity demands.

CONCLUSIONS

The social context of the home-work environment challenges the implementation of preventive interventions to reduce occupational hazards in HHC.
