Occupational exposure to chemical substances and health outcomes among hospital environmental services workers: A scoping review of international studies

Environmental services (EVS) workers are essential to preventing the spread of disease in hospitals. However, their exposure to hazardous chemicals and drugs is understudied. This scoping review will synthesize literature on hazardous chemical exposures and adverse health outcomes among EVS workers to identify research gaps and trends for further investigation. The scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure complete and accurate reporting. The scoping review included 25 studies on occupational exposure to chemicals among EVS workers in hospitals. Most studies focused on exposure to cleaning products, which led to dermal, respiratory, and ocular symptoms, oxidative stress, and inflammation. While personal protective equipment (PPE), training, education, and policies have the potential to enhance safety, further research is required to examine the long-term impacts of exposure and the cost-effectiveness of interventions. Future studies should utilize longitudinal approaches and self-reported data collection methods, such as diaries and interviews, to comprehensively assess exposure risks and develop effective interventions and policies. Future research is needed to understand the potential health risks faced by EVS workers from exposure to chemicals in hospitals. Longitudinal studies with objective exposure assessments and larger sample sizes should be conducted. Policies and interventions must be developed and implemented to improve safe work practices and reduce negative health outcomes.

Influence of occupational exposure to antineoplastic agents on adverse pregnancy outcomes among nurses: A meta-analysis

AIM

This study aimed to explore the relationship between nurses' occupational exposure to antineoplastic agents and adverse pregnancy outcomes.

DESIGN

Meta-analysis.

METHODS

Data were retrieved from studies published before April 2022 in PubMed, the Cochrane Library, the Web of Science, Embase databases, the China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBM), China Science and Technology Journal databases (VIP) and Wan Fang databases (WF). Stata MP (Version 17.0) was used to conduct this meta-analysis.

RESULTS

The current evidence shows that occupational exposure to antineoplastic agents increases nurses' risk of spontaneous abortions, stillbirths, and congenital abnormalities. It is necessary to pay attention to occupational exposures caused by antineoplastic agents, especially for female nurses of reproductive age. Managers should take timely and effective countermeasures to ensure their occupational safety and reduce the risk of adverse pregnancy outcomes.

Personal protective equipment for antineoplastic safety

ABSTRACT

Nurses must protect themselves while handling hazardous drugs or contaminated items. Wearing personal protective equipment (PPE) will reduce contact and prevent any acute or chronic adverse reactions that may occur from unintentional exposure. This article reviews PPE for antineoplastic safety and evidence-based guidelines for their use.

Systematic review of genotoxicity induced by occupational exposure to antineoplastic drugs

With increasing numbers of cancer cases, the use of antineoplastic agents is expected to rise. This will be accompanied by an increase in occupational exposure, which can cause unwanted health effects in workers. Our aim was to give an overview of genotoxic and epigenetic effects after occupational exposure to antineoplastic agents and to assess the concentration-effect relation. Four databases were searched for papers investigating genotoxic and/or epigenetic effects of occupational exposure to antineoplastic agents. Out of the 245 retrieved papers, 62 were included in this review. In this systematic literature review, we confirmed that exposure of healthcare workers to antineoplastic agents can lead to genotoxic damage. However, we observed a lack of data on exposure as well as genotoxic and epigenetic effects in workers other than healthcare workers. Furthermore, gaps in the current knowledge regarding the potential epigenetic effects caused by antineoplastic drug exposure and regarding the link between internal antineoplastic drug concentration and genotoxic and epigenetic effects after occupational exposure to antineoplastic agents were identified, offering a first step for future research.

Design of Analytical Method Validation Protocol Evaluating Environmental Monitoring of AND Contamination on Surfaces Based on Cleaning Validation Procedures: A Multi Component RP-UHPLC Method

Environmental monitoring of anti-neoplastic drug (AND) residues in workplaces is crucial to limit exposure to workers who handle with them. Although wipe sampling is the most appropriate methodology to evaluate the risk, conflicting results are also reported due to the lack of standardized and validated procedures. In this study, procedures for surface contamination of ANDs in workplaces are presented, with a focus on sampling, sample preparation and instrumentation. The analytical method validation parameters are designed to comply with requirements of The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) Q7 Good Manufacturing Practice (GMP) for active pharmaceutical ingredients. Additionally, the study provides a simple, specific, rapid and multi-component analytical method to evaluate seven ANDs that are Gefitinib, Imatinib, Dasatinib, Axitinib, Erlotinib, Nilotinib and Sorafenib at very low concentration levels, simultaneously. Quantitative, precise and reproducible results obtained from the study show that environmental monitoring procedure and analytical method validation protocol presented in the study can be used to reduce and monitor occupational exposure risk to ANDs in wokplaces.

Closed safety system for administration (CSSA): proposal for a new cytotoxic chemotherapy acronym

Exposure to cytotoxic chemotherapy can result in acute and chronic conditions including nausea, headaches, rashes, miscarriages, infertility and genetic aberrations. Surface contamination can occur during drug administration, and can subsequently spread throughout the healthcare environment. Dermal contact with contaminated surfaces can lead to drug absorption. Closed system drug-transfer devices (CSTDs) were initially developed to protect pharmacists during compounding. Components include a vial adapter to prevent pressurisation leakage and a syringe connector for transferring the drug to the intravenous infusion bag. Membrane-based CSTDs require a Luer adapter for drug administration whereas Luer system-based products do not. Most European nurses are familiar with needleless connectors. Unfortunately, these devices do not provide protection from chemotherapy exposure. To decrease confusion, CytoPrevent, a multi-national, primarily European organisation has proposed the term 'closed safety system for administration' (CSSA) for Luer based CSTDs. Along with education, the new term can help promote safety for nurses administering cytotoxic chemotherapy.

Development and psychometric testing of the safety climate instrument suitable for nurses handling chemotherapy drugs

AIM

To develop and test the psychometric properties of the Taiwanese safety climate instrument suitable for nurses handling chemotherapy drugs.

DESIGN

This is an instrument development study.

METHOD

All four stages, including questionnaire design, expert consultation, cognitive testing and psychometric validation, were used in this study. The data were collected between August and December 2018. Nurses with experience in handling chemotherapy drugs (N = 484) at one medical centre and two regional hospitals in Taiwan completed this instrument. Data were randomly split into two groups: one group (N = 237) for exploratory factor analysis and the other (N = 247) for confirmatory factor analysis.

RESULTS

The instruments' items were based on qualitative research, and the content validity index levels exceeded the acceptable value. An exploratory factor analysis revealed 43 items remaining in six factors, which accounted for 74.4% of variance. The result of the confirmatory factor analysis verified the acceptability of a 43-item model. The composite reliability values, Cronbach's alpha values, convergent validity and discriminant validity for each factor exceeded the acceptable value.

CONCLUSION

Most climate safety instruments used in the health care sector focus mainly on patient safety outcomes. Furthermore, there is no safety climate instrument for handling chemotherapy drugs, and there is a cultural difference. Through the development and validation process, we have developed a new instrument suitable for nurses handling chemotherapy drugs, which has good psychometric properties.

IMPACT

This instrument is valuable as its development was based on the concept of a safety climate for health care perceptions and qualitative survey findings. Hospital managers can use this instrument regularly to evaluate nurses' perceptions of the safety climate to determine the strengths and weaknesses of their workplace, thereby assisting organizational managers in proposing concrete actions.

Improving nurses' performance in the safe handling of antineoplastic agents: a quasi-experimental study

Background

The safe and standard handling of antineoplastic drugs can reduce the effects of occupational exposure and promote safe behaviors in nurses. Thus, the present study aimed to determine the effects ofstandard guidelines education on the safe handling of antineoplastic drugs among oncologynurses in Ardabil, Iran.

Methods

Thequasi-experimental study with a one-group pretest-posttest design was performed among 32 nursesworking in the oncology wards of two educational hospitals in Ardabil city, during 2020. Allthe nurses in the wards who met the inclusion criteria participated in the study. The data were collectedby usinga demographic information form and nurses’knowledge assessment questionnaire regardingthe standard guidelines for working with antineoplastic drugs, and a standard checklist for examiningtheir performance in this regard. Subsequently, they were analyzed by descriptive (mean and standard deviation) and inferential statistics (t-test)and Pearson’s correlation coefficient) in SPSS 22.

Results

The mean and standard deviation of the knowledge and performance scores of the oncology nurses was59.56±6.41and 18.96±2.54 respectively, which changed to 66±4.82 and 32.03±2.45 respectively three months after training. The results of the t-test represented a statistically significant difference between the level of knowledge and performance before and after the intervention (P=0.001).

Conclusions

Based on the results, the standard guidelines education improved the nurses’ knowledge and performance on the safe handling of antineoplastic drugs in the chemotherapy wards. Therefore, it is advised to increase the awareness of the oncology nurses in this regard in the planning and policy-making ofhealthcare centers.

Population-Based Study on Cancer Incidence in Pharmacist: A Cohort Study in Taiwan

Cancer is increasing in rate globally and is leading cause of death among no communicable chronic diseases (NCDs) after cardiovascular disease (CVD). Most of the research focuses on the risk of occupational injury, job stress, mental illness, substance abuse and workplace safety in physicians and nurses. However, fewer studies have investigated the risk of cancer in pharmacists. We compared the matched general population to investigate the risk of cancer in pharmacists in Taiwan. Data were obtained from the Health and Welfare Data Science Center of the Ministry of Health and Welfare in Taiwan. We established a pharmacist group that included 11,568 pharmacists and selected a 4-fold comparison (n = 46,272) for the non-clinics comparison group, frequency being matched by age, gender and Charlson Comorbidity Index (CCI) score. The pharmacists had a lower but non-significant risk of all cancer (Adjusted hazard ratio [aHR] = 0.96; 95% confidence interval [CI] = 0.85–1.07) compared with the general population. Female pharmacists had a higher risk of cancer than male pharmacists ([aHR] = 1.23; 95% CI = 1.06–1.43). Pharmacists had higher risks of breast cancer in females (aHR = 1.68; 95% CI = 1.35–2.08) and of prostate cancer in males (aHR = 2.18; 95% CI = 1.35–2.08) when compared with the general population. Occupational risk factors could play a role, but they were not evaluated. These epidemiological findings require additional studies to clarify cancer risk mechanisms in pharmacists.

Degradation and inactivation efficacy of ozone water for antineoplastic drugs in hospital settings

PURPOSE

Occupational exposure to antineoplastic drugs in hospital settings is recognized to be hazardous, and as such environmental decontamination including degradation and inactivation of such drugs is recommended. To data, although various agents such as oxidants have been reported to be useful for decontamination, simpler, safer, and more convenient methods are required. In this study, the degradation and inactivation efficacy of ozone water, which has newly been introduced for decontamination of antineoplastic drugs in spills, was investigated for formulations of gemcitabine, irinotecan, and paclitaxel.

METHODS

Antineoplastic formulations (medicinal ingredient: ∼1.5 μmol) were mixed with 50 mL of ozone water (>4 mg/L). The reactions were monitored by high-performance liquid chromatography, and the degradation mixtures were analyzed by ¹H nuclear magnetic resonance spectroscopy in order to obtain the structural information of the degradation products. The formulations of gemcitabine and irinotecan and those degradation mixtures were evaluated for their mutagenicity using the Ames test and cytotoxicity against human cancer cells.

RESULTS

gemcitabine and irinotecan were found to be readily degraded by the ozone treatment, and their active sites were suggested to be degraded. In contrast, paclitaxel was hard to be decomposed, possibly owing to the consumption of ozone by the polyoxyethylene castor oil added as a pharmaceutical additive of the formulation. No significant mutagenic changes of Salmonella typhimurium strains used for the Ames test were observed for the samples within the concentration ranges examined. The ozone treatment showed obvious increases in cell viability for gemcitabine formulation, and mild increases for irinotecan formulation.

CONCLUSIONS

Ozone water was shown to be effective as a decomposition agent for the antineoplastic drug formulations examined, although the efficacy depends on the chemical structures of the drugs and the pharmaceutical additives. It was also suggested that ozone treatment has a tendency to decrease the toxicity of the antineoplastic drug formulations. As such, further studies are required in order to clarify the effects and application limitations of ozone water.

Occupational exposure to antineoplastic drugs: what about hospital sanitation personnel?

OBJECTIVE

Occupational exposure to antineoplastic drugs (ANPs) occurs mainly through dermal contact. Our study was set up to assess the potential exposure of hospital sanitation (HS) personnel, for whom almost no data are available, through contamination of surfaces they regularly touch.

METHODS

In the oncology departments of two hospitals around Montreal, surface wipe samples of 120-2000 cm² were taken at 10 sites cleaned by the HS personnel and five other sites frequently touched by nursing and pharmacy personnel. A few hand wipe samples were collected to explore skin contamination. Wipes were analyzed by ultra-performance liquid chromatography tandem-mass spectrometry for 10 ANPs.

RESULTS

Overall, 60.9% of 212 surface samples presented at least one ANP above the limits of detection (LOD). Cyclophosphamide and gemcitabine were most often detected (52% and 31% of samples respectively), followed by 5-fluorouracil and irinotecan (15% each). Highest concentrations of five ANPs were found in outpatient clinics on toilet floors (5-fluorouracil, 49 ng/cm²; irinotecan, 3.6 ng/cm²), a perfusion pump (cyclophosphamide, 19.6 ng/cm²) and on a cytotoxic waste bin cover (gemcitabine, 4.97 ng/cm²). Floors in patient rooms had highest levels of cytarabine (0.12 ng/cm²) and methotrexate (6.38 ng/cm²). Hand wipes were positive for two of 12 samples taken on HS personnel, seven of 18 samples on nurses, and two of 14 samples on pharmacy personnel.

CONCLUSIONS

A notable proportion of surfaces showed measurable levels of ANPs, with highest concentrations found on surfaces cleaned by HS personnel, who would benefit from appropriate preventive training. As potential sources of worker exposure, several hospital surfaces need to be regularly monitored to evaluate environmental contamination and efficacy of cleaning.

Spatial and Temporal Variability in Antineoplastic Drug Surface Contamination in Cancer Care Centers in Alberta and Minnesota

The health risks of exposure to antineoplastic drugs (ADs) are well established, and healthcare professionals can be exposed while caring for cancer patients receiving AD therapy. Studies conducted worldwide over the past two decades indicate continuing widespread surface contamination by ADs. No occupational exposure limits have been established for ADs, but concerns over exposures have led to the development of guidelines, such as United States Pharmacopeia (USP) General Chapter <800> Hazardous Drugs-Handling in Healthcare. While recommending regular surveillance for surface contamination by ADs these guidelines do not provide guidance on sampling strategies. Better characterization of spatial and temporal variability of multidrug contamination would help to inform such strategies. We conducted surface-wipe monitoring of nine cancer care centers in Alberta, Canada and Minnesota, USA, with each center sampled eight times over a 12-month period. Twenty surfaces from within pharmacy and drug administration areas were sampled, and 11 drugs were analyzed from each wipe sample. Exposure data were highly left-censored which restricted data analysis; we examined prevalence of samples above limit of detection (LOD), and used the 90th percentile of the exposure distribution as a measure of level of contamination. We collected 1984 wipe samples over a total of 75 sampling days resulting in 21 824 observations. Forty-five percent of wipe samples detected at least one drug above the LOD, but only three of the drugs had more than 10% of observations above the LOD: gemcitabine (GEM) (24%), cyclophosphamide (CP) (16%), and paclitaxel (13%). Of 741 wipe samples with at least one drug above LOD, 60% had a single drug above LOD, 19% had two drugs, and 21% had three drugs or more; the maximum number of drugs found above LOD on one wipe was 8. Surfaces in the compounding area of the pharmacy and in the patient area showed the highest prevalence of samples above the LOD, including the compounding work surface, drug fridge handle, clean room cart, passthrough tray, and hazardous drug room temperature storage, the IV pump keypad, patient washroom toilet handle, patient washroom door handle, nurses' storage shelf/tray, and patient side table. Over the course of the study, both 90th percentiles and prevalence above LOD varied without clear temporal patterns, although some centers appeared to show decreasing levels with time. Within centers, the degree of variability was high, with some centers showing changes of two to three orders of magnitude in the 90th percentile of drug concentrations month to month. A clear difference was observed between the six centers located in Alberta and the three in Minnesota, with Minnesota centers having substantially higher percentages of samples above the LOD for CP and GEM. Other factors that were associated with significant variability in exposures were drug compounding volume, size of center, number of patients seen, and age of the center. We hope that demonstrating variability associated with drug, surface, clinic-factors, and time will aid in a better understanding of the nature of AD contamination, and inform improved sampling strategies.

Oral Chemotherapy: An Evidence-Based Practice Change for Safe Handling of Patient Waste

BACKGROUND

Safe handling practices for patient waste have focused on patients receiving IV chemotherapy, but these practices do not address safe handling for patients receiving oral chemotherapy.

OBJECTIVES

The aim of this article is to evaluate evidence and formulate best practice recommendations for handling and disposing waste from patients receiving oral chemotherapy.

METHODS

A literature search established a framework for the project. For healthcare providers and staff, procedures were established to access biohazard supplies and to follow safe handling of patient waste post-oral chemotherapy administration. Supply cost utilization was evaluated pre- and postimplementation. Staff perceptions were assessed six months after project implementation.

FINDINGS

The cost of supplies per patient day increased minimally. Staff self-reported use of biohazard precautions when handling patients' waste increased. The majority of staff reported that they had access to supplies and were knowledgeable regarding safe handling procedures six months after this practice change.

Occupational exposure assessment in professionals who manipulate and administer antineoplastic drugs in a university hospital in Southern Brazil

INTRODUCTION

Our goal was to demonstrate the effects of occupational exposure to antineoplastic drugs on oxidative stress parameters and DNA damage in health professionals who manipulate and administer antineoplastic drugs in a University Hospital in Southern Brazil.

METHODS

The case-control study with a longitudinal design, involved 64 individuals, 29 of them pharmacists, pharmacy technicians and nurses who were occupationally exposed to antineoplastic drugs and 35 professionals who were not exposed. Gene mutations were determined by micronucleus from salivary fluid; DNA damage by comet assay and oxidative stress parameters in whole blood were also evaluated.

RESULTS

All workers exposed to antineoplastic drugs used personal protective equipment (PPE). It was demonstrated that the total nonprotein thiol and thiobarbituric acid reactive substances levels showed interaction between group and time, with higher levels one week after handling/administration of antineoplastic drugs in the exposed group (GEE, p ≤ 0.0001 and p = 0,013, respectively). Additionally, there was a group effect on the activities of the catalase and glutathione peroxidase antioxidant enzymes (GEE, p = 0.027 and p ≤ 0.0001, respectively), and workers occupationally exposed to antineoplastic drugs had higher enzyme activities compared to those not exposed. No genotoxic damage was demonstrated through the evaluated parameters.

CONCLUSIONS

Despite the correct use of PPE, professionals occupationally exposed to antineoplastic drugs were more susceptible to oxidative stress than those not exposed. The evaluation of the studied parameters is especially important for the definition of conducts and practices in the area, always in search of guaranteeing the establishment of a rational policy to protect workers' health.

Factors influencing precautions against antineoplastic drug exposure among nurses and nurse assistants in Thailand

BACKGROUND

Antineoplastic drugs (AD) are important chemical risks for healthcare workers. Precautions against AD exposure include the use of appropriate personal protective equipment (PPE). Evaluation of PPE usage during patient care processes has not been reported in Thailand. We aimed to evaluate the level of PPE usage and factors predicting PPE usage among nurses and nurse assistants in Thailand.

METHODS

A cross-sectional survey was conducted in a university hospital and two general hospitals. The questionnaires covered demographic characteristics, self-reported use of PPE and 7 predictive factors. Mixed-effects modeling was used to determine the association between standardized score of predictive factors and PPE usage score.

RESULTS

The response rate was 78.6% and 884 participants were left for analysis after data cleaning. Among nurses (n = 499), higher PPE usage score was associated with self-efficacy (β = 0.28, 95% CI 0.21, 0.34), workplace safety climate (β = 0.27, 95% CI 0.20, 0.34), and conflict of interest (β = - 0.07, 95% CI - 0.14, - 0.01). Among nurse assistants (n = 385), higher PPE usage score was associated with self-efficacy (β = 0.27, 95% CI 0.18, 0.36), interpersonal influence (β = 0.14, 95% CI 0.04, 0.24), workplace safety climate (β = 10.29, 95% CI 0.19, 0.38), and conflict of interest (β = - 0.14, 95% CI - 0.24, - 0.03).

CONCLUSIONS

Several factors were associated with PPE usage among nurses and nurse assistants. Improved PPE usage against AD can be promoted through interventions that modify those factors.

Advanced Medical Devices for Preparation and Administration of Chemotherapeutic Agents: Results from a Multi-Dimensional Evaluation

Purpose

To evaluate the incremental benefits concerning the implementation of closed-system medical devices for the preparation and administration of chemotherapy agents (integrated or not with traceable workflow), within an Italian clinical practice, in which the use of such technologies is not standardized.

Methodology

Four Scenarios, implying different levels of technologies introduction, were analyzed, based on the presence and/or absence of closed systems and traceable workflow, in the preparation and in the administration phase. A literature review was conducted, in order to retrieve efficacy and safety measures. Economic and organizational benefits, assuming a hospitals perspective, were assessed by means of health-economics tools, considering 27,660 (±695.86) drugs on average prepared, on an annual basis, by 12 hospitals involved. The typology of medical devices and other devices/equipment used, the human resources involved, and the time spent for the preparation and administration phases were collected.

Results

Literature stated that the introduction of advanced technologies (CSTDs in the preparation phase, closed-system in the administration phase, both integrated by a traceable workflow) could: i) decrease surface contamination (12.24% vs 26.39%, P<0.001) and ii) improve the capability to identify dosage errors (7% vs 0.096%, P<0.05). The above technologies presented the best trade-off between cost sustained and efficacy gained. Despite marginal investments (ranging from +1% to +6%) being required for their acquisition, an organizational saving equal to more than 1,000 working hours emerged, which could be spent on other hospital activities.

Conclusion

The implementation of closed systems, integrated with a traceable workflow grounding on gravimetric control, may be considered a valid technological alternative within the investigated setting. The marginal incremental costs could be absorbed already in the first year after their introduction, in particular, because of the potential time saving in using closed systems in both the preparation and administration phases, demonstrating the sustainability and feasibility of such advanced technologies.

Surface Contamination by Antineoplastic Drugs in Two Oncology Inpatient Units

Background

Hazardous drugs pose risks to health care workers. To reduce the risk of occupational exposure for all workers, several protective and monitoring measures have been recommended and implemented over the past two decades. This study was undertaken to describe traces contamination with ten antineoplastic drugs in the oncology care unit of two university hospitals.

Methods

In this descriptive interrupted time series study, data was collected in two hospitals (a pediatric hospital and an adult hospital) in two consecutive years (12 December 2017 and 27 March 2018, defined as Period 1; 17 April 2019 and 12 June 2019, defined as Period 2). In both Period 1 and Period 2, 36 sites were sampled in each inpatient care unit to explore the contamination of surfaces with hazardous drugs.

Results

A total of 144 samples from the oncology care unit of the two hospitals were obtained for measurement. Overall, 40 % (58/144) of the sampling sites were positive for at least one hazardous drug. In the pediatric centre, 50 % (18/36) and 36 % (13/36) of the sites sampled in Period 1 and Period 2, respectively, were positive for at least one hazardous drug, whereas in the adult hospital, the percentage of sites that were positive for at least one hazardous drug was 19 % (7/36) in Period 1 and 56 % (20/36) in Period 2.

Conclusion

The surfaces of inpatient care units sampled in this study were contaminated with antineoplastic drugs, and contamination was present throughout the care units (including structures, furniture, medical equipment, and office equipment). Hospitals’ environmental surveillance programs should encompass inpatient care units.

Reproductive toxic agents in work environments and related cases in Korea

There has been a growing concern and subsequent interest surrounding numerous reproductive toxic agents found in various working and non-working environments. Meanwhile, there have been many efforts in medical fields such as toxicology and epidemiology applying experimental studies to elucidate reproductive toxic agents' characterization and health effects. However, there remains insufficient research data and inadequate evidence in humans. Adverse reproductive outcomes vary from transient, moderate health effects to severely detrimental consequences, such as permanent infertility or childhood cancer of one's offspring. Furthermore, upon exposure to toxic agents, the latent period before reproductive health effects are observed is relatively short compared to other occupational diseases (e.g., occupational cancer); instant action is required once exposure to reproductive toxic agents is detected. Therefore, it is very important for workers and healthcare professionals to know about the reproductive toxic agents they are likely to be exposed to. In this review, we discuss the general epidemiology of reproductive health in Korea, and the information regarding these reproductive toxic agents.

Study protocol for the assessment of nurses internal contamination by antineoplastic drugs in hospital centres: a cross-sectional multicentre descriptive study

INTRODUCTION

Antineoplastic drugs (AD) are potentially carcinogenic and/or reprotoxic molecules. Healthcare professionals are increasingly exposed to these drugs and can be potentially contaminated by them. Internal contamination of professionals is a key concern for occupational physicians in the assessment and management of occupational risks in healthcare settings. Objectives of this study are to report AD internal contamination rate in nursing staff and to identify factors associated with internal contamination.

METHODS AND ANALYSIS

This trial will be conducted in two French hospital centres: University Hospital of Bordeaux and IUCT-Oncopole of Toulouse. The target population is nurses practicing in one of the fifteen selected care departments where at least one of the five studied AD is handled (5-fluorouracil, cyclophosphamide, doxorubicin, ifosfamide, methotrexate). The trial will be conducted with the following steps: (1) development of analytical methods to quantify AD urine biomarkers, (2) study of the workplace and organization around AD in each care department (transport and handling, professional practices, personal and collective protection equipments available) (3) development of a self-questionnaire detailing professional activities during the day of inclusion, (4) nurses inclusion (urine samples and self-questionnaire collection), (5) urine assays, (6) data analysis.

ETHICS AND DISSEMINATION

The study protocol has been approved by the French Advisory Committee on the Treatment of Information in Health Research (CCTIRS) and by the French Data Protection Authority (CNIL). Following the opinion of the Regional Committee for the Protection of Persons, this study is outside the scope of the provisions governing biomedical research and routine care (n°2014/87). The results will be submitted to peer-reviewed journals and reported at suitable national and international meetings.

TRIAL REGISTRATION NUMBER

NCT03137641.

Self-Reported Skin Disorders Among Health Care Workers

This study aimed to estimate the point prevalence and 1-year period prevalence of skin disorder symptoms (SDS) among health care workers (HCWs) and to explore the possible risk factors. A random sample of 400 HCWs from 13 government health centers in Brunei Darussalam self-administered an adapted Nordic Occupational Skin Questionnaire (NOSQ-2002/SHORT). The point and 1-year prevalence of SDS were 12% and 19%, respectively. Having a history of SDS before the current job, exposure to SDS-exacerbating materials at the workplace, and having clinical roles were correlated for both prevalence estimates. Frequent handwashing and moderate use of latex gloves were associated with higher risk of SDS at 1-year. Female HCWs were more likely to report SDS. In multivariate analyses, only contact with SDS-exacerbating materials at the workplace, prejob SDS, and moderate glove usage were significant predictors of SDS.

A decontamination process adding a tensioactive agent and isopropanol to a closed-system drug transfer device for better control of isolator contamination. A prospective, parallel study

Background

Despite the use of closed system drug transfer devices (CSTD), residual contamination from antineoplastic drugs is still detected inside isolators. The aim of this study was to compare the decontamination level obtained using a CSTD + standard cleaning procedure with a CSTD + standard cleaning procedure + specific decontamination procedure.

Methods and findings

A comparative and prospective study was carried out in a newly opened compounding unit. Compounding was performed with a CSTD (BD-Phaseal, Becton-Dickinson). In the Control isolator (C), the cleaning process was completed daily with a standard biocide solution (Anioxyspray^TM, Anios, France). In the Intervention isolator (I), weekly decontamination with a homemade admixture of sodium dodecyl sulfate 10⁻² M/70% isopropanol (80/20, v/v) was added. Monitoring was performed via a validated LC-MS/MS method. Eight drugs (cyclophosphamide, cytarabine, dacarbazine, fluorouracile, gemcitabine, ifosfamide, irinotecan and methotrexate) were monitored daily over 14 consecutive weeks on three sites inside the isolators: gloves, workbench and window. Results are presented as the odds-ratio (OR) of contamination and as overall decontamination efficiency (Eff_Q, %). The proportion of Eff_Q ≥ 90% was assessed by a Fisher’s exact test (p<0.05). Overall contamination rates (CR, %) were significantly different from one isolator to the other (CR_C = 25.3% vs. CR_I = 10.4%; OR = 0.341; p<0.0001). Overall Eff_Q values (median; 1^st and 3^rd quartiles) were higher in the intervention isolator (I: 78.3% [34.6%;92.6%] vs. C: 59.5% [-5.5%;72.6%]; p = 0.0015) as well as the proportion of days with an Eff_Q ≥ 90% (I: 42.9% vs. C: 7.1%; p = 0.077) but very variable depending on drugs.

Conclusion

Adding a decontamination protocol with a tensioactive agent to a CSTD leads to better control of chemical contamination inside isolators. Improving decontamination by increasing decontamination frequency or modifying the protocol will be further studied.
