Guidelines for safe handling of hazardous drugs: A systematic review

Influences Shaping Clinicians' Monoclonal Antibody and Immune Checkpoint Inhibitor Preparation and Administration Management Practices: A Systematic Review

OBJECTIVES

In 30 years, monoclonal antibodies (mAbs) and immune checkpoint inhibitors (ICPIs) have enhanced cancer survival and quality of life. Limited knowledge exists regarding the long-term risks of repeated exposure, especially for cancer nurses, who prepare and administer them. This systematic review aimed to identify influences shaping clinicians' awareness and practices in the safe preparation and administration of mAbs and ICPIs.

DATA SOURCES

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The databases CINAHL, EMBASE, Joanna Briggs Institute, OVID, MEDLINE, and Cochrane were searched. Eligibility and risk of bias were assessed by four reviewers.

RESULTS

Of 7301 identified studies, 481 duplicates were removed, and 6673 were excluded after title and abstract review. A full-text review was conducted on 147 studies; six studies were included. A narrative synthesis generated two themes: (1) ambiguity contributes to variation in handling practices and (2) continuing professional development (CPD) is vital but hard to implement without evidence.

CONCLUSION

Lack of evidence regarding long-term risks and consensus creates uncertainty about the hazardous nature of unconjugated mAbs and ICPIs. Resulting in varied risk reduction strategies during preparation and administration, and inconsistent CPD. Protecting the long-term health of clinicians necessitates consensus on risk reduction strategies. This will be challenging without compelling evidence or international agreement on their hazardous classification.

IMPLICATIONS FOR NURSING PRACTICE

In nursing, policy gaps and inconsistent CPD related to unconjugated mAbs and ICPIs may expose nurses to risks. Understanding the educational needs of nurses and global standardized guidelines are urgently needed.

Quality assurance standards and their use in the preparation of parenteral systemic anticancer therapy products in healthcare establishments: a scoping review

OBJECTIVES

The use of parenteral systemic anticancer therapy (SACT) has led to improved cancer survival. A quality assurance (QA) system of the aseptic compounding process is necessary to ensure safe and consistent production of parenteral SACT. This scoping review identifies international evidence and practice relating to QA standards in the preparation of parenteral SACT in healthcare establishments.

METHODS

Standards relating to aseptic compounding in hospital pharmacies and literature exploring the aseptic compounding of parenteral SACT were included. Literature relating to the non-aseptic compounding of medicines and records specific to sterile manufacturing in industrial settings were excluded. A search of several electronic databases, trial registries, the grey literature and websites of key European hospital pharmacy groups and accreditation bodies was conducted on 16 March 2022. A narrative discussion was performed by country, and content analysis of articles was conducted.

RESULTS

Thirty-seven records were included. Standards reviewed covered the work environment, the preparation process and the safety of the workers who are potentially exposed to hazardous chemicals. It was a common practice to include frequent audits to ensure adherence to standards. Some standards also recommended external inspections to allow for further learnings. Periodic reviews are encouraged to ensure standards maintain relevance. National standards of the countries reviewed were based on international standards, with minor adaptations for local conditions.

CONCLUSIONS

The main limitation of this review is that it is limited to countries with a high human development index. The review shows that the use of an internationally recognised standard as a basis for national standards is best practice, and will allow for relevance into the future.

Longitudinal evaluation of environmental contamination with hazardous drugs by surface wipe sampling

INTRODUCTION

Exposure of healthcare workers to hazardous drugs can lead to adverse health effects supporting the importance of a continuous monitoring program, for example, by taking surface wipe samples. The objective was to describe the results of repeated monitoring of contamination with hazardous drugs on multiple surfaces in a hospital pharmacy and at two wards using standardized preparation techniques and cleaning procedures.

METHODS

Twelve surfaces in the hospital pharmacy and at two wards were sampled and analyzed for contamination with the hazardous drugs cyclophosphamide, doxorubicin, 5-fluorouracil, gemcitabine, methotrexate, and paclitaxel. The drugs were prepared with a closed-system drug transfer device (CSTD). Sampling of the drugs was performed in four trials during eight months. Liquid chromatography tandem mass spectrometry was used for the analysis of the drugs.

RESULTS

During the four trials, contamination with five of the six hazardous drugs was found on half of the surfaces in the pharmacy and in a ward. Seventeen out of 288 possible outcomes were positive (6%), with the biological safety cabinet grate (n = 6) and scanner (n = 5) most frequently contaminated. The highest level of contamination was observed on the pass-thru window (cyclophosphamide: 2.90 ng/cm2) and the touch screen of the Diana device (5-fluorouracil: 2.38 ng/cm2). Both levels were below the action level of 10 ng/cm2.

CONCLUSIONS

The long-term use of a CSTD in combination with appropriate cleaning has proven effective in achieving low levels of surface contamination with hazardous drugs.

Inhaled Medicines for Targeting Non-Small Cell Lung Cancer

Throughout the years, considerable progress has been made in methods for delivering drugs directly to the lungs, which offers enhanced precision in targeting specific lung regions. Currently, for treatment of lung cancer, the prevalent routes for drug administration are oral and parenteral. These methods, while effective, often come with side effects including hair loss, nausea, vomiting, susceptibility to infections, and bleeding. Direct drug delivery to the lungs presents a range of advantages. Notably, it can significantly reduce or even eliminate these side effects and provide more accurate targeting of malignancies. This approach is especially beneficial for treating conditions like lung cancer and various respiratory diseases. However, the journey towards perfecting inhaled drug delivery systems has not been without its challenges, primarily due to the complex structure and functions of the respiratory tract. This comprehensive review will investigate delivery strategies that target lung cancer, specifically focusing on non-small-cell lung cancer (NSCLC)-a predominant variant of lung cancer. Within the scope of this review, active and passive targeting techniques are covered which highlight the roles of advanced tools like nanoparticles and lipid carriers. Furthermore, this review will shed light on the potential synergies of combining inhalation therapy with other treatment approaches, such as chemotherapy and immunotherapy. The goal is to determine how these combinations might amplify therapeutic results, optimizing patient outcomes and overall well-being.

Computer programs used in the field of hospital pharmacy for the management of dangerous drugs: systematic review of literature

Background

This review wants to highlight the importance of computer programs used to control the steps in the management of dangerous drugs. It must be taken into account that there are phases in the process of handling dangerous medicines in pharmacy services that pose a risk to the healthcare personnel who handle them. Objective: To review the scientific literature to determine what computer programs have been used in the field of hospital pharmacy for the management of dangerous drugs (HDs).

Methods

The following electronic databases were searched from inception to July 30, 2021: MEDLINE (via PubMed), Embase, Cochrane Library, Scopus, Web of Science, Latin American and Caribbean Literature in Health Sciences (LILACS) and Medicine in Spanish (MEDES). The following terms were used in the search strategy: "Antineoplastic Agents," "Cytostatic Agents," "Hazardous Substances," "Medical Informatics Applications," "Mobile Applications," "Software," "Software Design," and "Pharmacy Service, Hospital."

Results

A total of 104 studies were retrieved form the databases, and 18 additional studies were obtained by manually searching the reference lists of the included studies and by consulting experts. Once the inclusion and exclusion criteria were applied, 26 studies were ultimately included in this review. Most of the applications described in the included studies were used for the management of antineoplastic drugs. The most commonly controlled stage was electronic prescription; 18 studies and 7 interventions carried out in the preparation stage focused on evaluating the accuracy of chemotherapy preparations.

Conclusion

Antineoplastic electronic prescription software was the most widely implemented software at the hospital level. No software was found to control the entire HD process. Only one of the selected studies measured safety events in workers who handle HDs. Moreover, health personnel were found to be satisfied with the implementation of this type of technology for daily work with these medications. All studies reviewed herein considered patient safety as their final objective. However, none of the studies evaluated the risk of HD exposure among workers.

Occupational Health of Health-Care Workers with Overnutrition: Scoping Review with Meta-Analysis

(1) Objective: To review the scientific literature on the impact of interventions to enhance the occupational health of health-care workers with overnutrition. (2) Methods: Scoping review with meta-analysis. Data were obtained by consulting the following bibliographic databases: MEDLINE (via PubMed), Embase, Cochrane Library, Scopus, Web of Science, Latin American and Caribbean Literature on Health Sciences (LILACS), and Medicina en Español (MEDES). The terms used as descriptors and as text in the title and abstract fields of the records were "health workers", "overnutrition", and "occupational health", using the filters "human", "adult": 19+ years", and "clinical trial". The search update date was January 2023. The documentary quality of the articles was evaluated using the CONSORT questionnaire and the presence of bias was assessed using the Rob 2.0 tool. (3) Results: From the 611 digitally retrieved references, 17 clinical trials were selected after applying the inclusion and exclusion criteria. CONSORT scores ranged from a minimum of 14.6% to a maximum of 91.7%, with a median of 68.8%. According to the SIGN criteria, this review provided "1" evidence with a grade B recommendation. Six different types of intervention were tested, grouped into strategies ranging from a single intervention to a combination of four interventions. The summary effect of the meta-analysis showed significant weight loss, but no association with reduced body mass index. (4) Conclusions: While workplace interventions have been shown to be potentially effective, and strategies using different types of interventions have been proven to be useful in tackling overnutrition, an effective and sustainable solution for changing the behavior of health professionals to tackle overweight and obesity has yet to be identified.

Occupational Exposure to Antineoplastic Drugs in Twelve French Health Care Setting: Biological Monitoring and Surface Contamination

Antineoplastic drugs used in the treatment of cancers have an intrinsic toxicity, because of their genotoxic, teratogenic, and carcinogenic properties. Their use is recognized as an occupational hazard for healthcare workers (HCWs) who may be exposed. The purpose of this article is to present biological- and environmental-monitoring data collected in twelve French hospitals over eight years. Urine samples were collected from a wide range of HCWs (250 participants) from pharmacy and oncology units, including physicians, pharmacists, pharmacy technicians, nurses, auxiliary nurses, and cleaners. The investigated drugs were cyclophosphamide, ifosfamide, methotrexate, and α-fluoro-β-alanine, the main urinary metabolite of 5-fluorouracil. Wipe samples were collected from various locations in pharmacy and oncology units. More than 50% of participants, from all exposure groups, were contaminated with either drug, depending on the unit, the day, or the task performed. However, workers from oncology units were more frequently exposed than workers from pharmacy units. Significant contamination was detected on various surfaces in pharmacy and oncology units, highlighting potential sources of exposure. Risk-management measures should be implemented to reduce and maintain exposures at lowest-possible levels. In addition, regular exposure assessment, including biological and environmental monitoring, is recommended to ensure the long-term efficiency of the prevention measures.

Patients' knowledge and awareness of safe handling of oral anticancer agents at Sultan Qaboos University Hospital in Oman

BACKGROUND

Safe handling of oral anticancer agents is of great concern. There is a lack of clear, national guidelines on how patients can safely handle and dispose of unwanted medications. We aimed to evaluate the safe handling, storage, and disposal of oral anticancer drugs among cancer patients and caregivers at home.

METHOD

This cross-sectional survey of adult cancer patients (or their adult caregivers) used a closed-ended questionnaire from May 2019 to March 2020.

RESULTS

A total of 257 patients (50 ± 15 years; range: 18-93 years) were enrolled; however, only 91% (233/257) reported self-administering oral anticancer medications. Caregivers were more likely to administer oral anticancer agents for patients ≥60 years than those <40 years old (63% vs. 8%; P = 0.001). Most patients (52%; 133/257) did not wash their hands after administering the drug; 74% (164/222) of the respondents reported that their medications were kept in a bedroom cabinet, while 18% (40/222) stored their medications in a refrigerator, and 5% (12/222) in a kitchen cabinet. A total of 55% (68/124) of patients returned their excess oral chemotherapy medications to the hospitals; however, 36% (45/124) disposed of their unused oral chemotherapy drugs in a household garbage container.

CONCLUSION

While two-thirds of patients stored their oral anticancer medications properly, more than half used inappropriate handling procedures. Disposal practices were inconsistent and did not adhere to the reported international guidelines.

Chemotherapy supply chain management, safe-handling and disposal in Ethiopia: the case of Tikur Anbessa specialized hospital

Optimal chemotherapy management is substandard in low and middle-income countries. We aimed to identify major gaps to design interventional strategies for improved chemotherapy management at Tikur Anbessa Specialized Hospital (TASH), Ethiopia. This study was conducted using an observational checklist, open-ended questions, record review, and key informant interviews of department heads and focal persons at TASH. Findings were categorized into specific themes that developed. Chemotherapy represented 60.2% of the hospital medication budget. Drug utilization was quantified via monthly consumption documentation and forecasting. However, unreliable data resulted in frequent stockouts (unavailability of the item when it is needed) of chemotherapy with only 67.8% availability. Thirteen healthcare personnel (9 nurses, 2 pharmacists and 2 hospital cleaners) were interviewed: all clinical staff but neither of hospital cleaners believed that they were at risk of hazardous agents. Challenges identified included inadequate and frequent stockouts (unavailability of the item when it is needed) of personal protective equipment, lack of standardized guidelines for chemotherapy handling, admixture, and disposal, lack of designated preparation rooms, and lack of training. All nine nurses handled chemotherapy admixtures despite only two nurses previously receiving in-service training. Most of the participants had never witnessed the disposal of anticancer drugs. Prompted by the results of this study, a dialogue was initiated among members of TASH, the American Cancer Society and the University of North Carolina to implement action-oriented projects to address the gaps identified at TASH. These gaps directly and indirectly affect care and treatment outcomes of patients at a large cancer center. Collaborations with well-resourced centers are potential models for improving chemotherapy management.

Electrochemistry as a Powerful Tool for Investigations of Antineoplastic Agents: A Comprehensive Review

Cancer is most frequently treated with antineoplastic agents (ANAs) that are hazardous to patients undergoing chemotherapy and the healthcare workers who handle ANAs in the course of their duties. All aspects related to hazardous oncological drugs illustrate that the monitoring of ANAs is essential to minimize the risks associated with these drugs. Among all analytical techniques used to test ANAs, electrochemistry holds an important position. This review, for the first time, comprehensively describes the progress done in electrochemistry of ANAs by means of a variety of bare or modified (bio)sensors over the last four decades (in the period of 1982-2021). Attention is paid not only to the development of electrochemical sensing protocols of ANAs in various biological, environmental, and pharmaceutical matrices but also to achievements of electrochemical techniques in the examination of the interactions of ANAs with deoxyribonucleic acid (DNA), carcinogenic cells, biomimetic membranes, peptides, and enzymes. Other aspects, including the enantiopurity studies, differentiation between single-stranded and double-stranded DNA without using any label or tag, studies on ANAs degradation, and their pharmacokinetics, by means of electrochemical techniques are also commented. Finally, concluding remarks that underline the existence of a significant niche for the basic electrochemical research that should be filled in the future are presented.

Pharmaceutical Pollution in Aquatic Environments: A Concise Review of Environmental Impacts and Bioremediation Systems

The presence of emerging contaminants in the environment, such as pharmaceuticals, is a growing global concern. The excessive use of medication globally, together with the recalcitrance of pharmaceuticals in traditional wastewater treatment systems, has caused these compounds to present a severe environmental problem. In recent years, the increase in their availability, access and use of drugs has caused concentrations in water bodies to rise substantially. Considered as emerging contaminants, pharmaceuticals represent a challenge in the field of environmental remediation; therefore, alternative add-on systems for traditional wastewater treatment plants are continuously being developed to mitigate their impact and reduce their effects on the environment and human health. In this review, we describe the current status and impact of pharmaceutical compounds as emerging contaminants, focusing on their presence in water bodies, and analyzing the development of bioremediation systems, especially mycoremediation, for the removal of these pharmaceutical compounds with a special focus on fungal technologies.

A simple approach to assess the cancer risk of occupational exposure to genotoxic drugs in healthcare settings

Background

Several drugs for human use possess genotoxic properties as a necessary consequence of their intended therapeutic effect (e.g. antineoplastics). Health workers may be exposed to these chemicals in various occupational settings such as dose preparation and administration. To date, there are no quantitative risk assessment models to estimate the cancer risk of health workers due to the handling of genotoxic drugs. We therefore developed a quantitative risk assessment model to assess the cancer risk of occupational exposure to genotoxic drugs in healthcare settings based on the threshold of toxicological concern (TTC) concept. This model was used to evaluate the cancer risk of health workers due to the handling of genotoxic drugs in modern health care facilities.

Methods

We modified the threshold of toxicological concern (TTC) concept to fit the purpose of occupational cancer risk assessment. The risk model underlying ICH guideline M7 (R1): “assessment and control of DNA reactive (mutagenic) impurities in pharmaceuticals to limit potential carcinogenic risk” was used as a starting point for our model. We conducted a short review of studies on the occupational exposure of health workers to genotoxic drugs. These occupational exposure data were compared to the acceptable exposure levels resulting from our TTC based risk model.

Results

Based on the threshold of toxicological concern (TTC) concept, we defined an acceptable daily intake (ADI) of 4 μg/day as threshold of no concern for the exposure of health workers to genotoxic drugs. Regarding the dermal exposure of health workers to genotoxic drugs, we derived a corresponding acceptable surface contamination level (ASCL) of 20 ng/cm². Both ADI and ASCL are usually not exceeded in modern healthcare settings. Current safety precautions provide sufficient protection to health workers.

Conclusions

The application of our model indicates that workers in modern healthcare facilities are not at risk of developing work related cancer above widely accepted cancer risk levels due to the occupational exposure to genotoxic drugs. Hence, the present study may assist employers and public authorities to make informed decisions concerning the need for (further) protective measures and during risk communication to health workers.

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.

Optimisation of maintenance in delivery systems for cytostatic medicines

BACKGROUND

The real-world application of maintenance in organisations brings together a number of maintenance policies in order to achieve the desired availability, efficiency and profitability. However, the literature mostly chooses a single maintenance policy, and so the decision process is not suited to the real conditions in the company to which it is applied. Our study takes a combination of maintenance policies as alternatives, and so conforms to the actual practice of maintenance in organisations. Furthermore, it introduces the possibility of including extra spare parts, or outsourcing maintenance policies. Although the selection of maintenance policies has been applied to many kinds of business and of machine, there is almost no instance of its application to hospitals, and it has never been applied to delivery systems for cytostatic drugs.

METHODS

The model uses the fuzzy Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which is recognised as being highly suitable for solving group decision-making problems in a fuzzy environment. Fuzzy set theory is also considered to be more proficient than crisp numbers for handling the ambiguity, imprecisions, data scarcity, and uncertainty inherent in decisions made by human beings. The judgements required were obtained from a decision group comprising the heads of facilities maintenance, maintenance of medical equipment, health and safety at work, environment, and programming-admission. The group also included care staff; specifically, the heads of the main clinical services, and the medical supervisors. The model includes original criteria, such as Quality of health care, which measures impact on care as a function of mean availability of each alternative. It also considers Impact on hospital management via the criteria: Working environment in the organisation and Impact on health care; the former criterion measures equality among care services in the hospital, while the latter assesses the effect on regional health cover. The model was built using real data obtained from a state hospital in Spain. The model can also be easily applied to other national and international healthcare organisations, providing weights specific to the criteria. These are produced by a decision group from each healthcare organisation and the alternatives are updated in accordance with what is considered important in each hospital.

RESULTS

The results obtained from the model recommend changing the alternative that is currently in use, Corrective and Preventive Maintenance, to Corrective and Preventive Maintenance plus two spare hoods. This alternative would lead to an availability of 1 (the highest possible) in the systems for preparing personalised cytotoxic drugs, and so the quality of service is therefore very high. Additionally, it could offer services to all the users of the hospital, and also offer cover in the preparation of cytotoxic medicines to other hospitals in the catchment area.

CONCLUSIONS

The results suggest the possibility that improvements to the support and logistical systems, which include maintenance, traditionally held to have no effect on quality of care, may be key to improving care quality, but also in reducing risk to patients, care and non-care staff, and the environment.

An Improved LC-MS/MS Method for the Analysis of Thirteen Cytostatics on Workplace Surfaces

Cytostatics are drugs used in cancer treatment, which pose serious risks to healthcare workers. Dermal absorption via surface contamination is the key exposure route; thus, rapid, reliable, and validated analytical methods for multicomponent detection are crucial to identify the exposure risk. A surface-wipe-sampling technique compatible with hospitals' safety requirements (gauze, 1 mL isopropanol) and a fast and simple extraction method (1 mL acetonitrile, 20 min ultrasonic bath, evaporation, reconstitution in 200 µL acetonitrile), coupled with liquid chromatography-tandem mass spectrometry analysis, were developed. It allowed identification and quantification of 13 cytostatics on surfaces: cyclophosphamide, doxorubicin, etoposide, ifosfamide, paclitaxel, bicalutamide, capecitabine, cyproterone, flutamide, imatinib, megestrol, mycophenolate mofetil, prednisone. Good linearity, sensitivity, and precision were achieved (R² > 0.997, IDLs < 4.0 pg/cm², average CV 16%, respectively). Accuracy for four model surfaces (melamine-coated wood, phenolic compact, steel 304, steel 316) was acceptable (80 ± 12%), except for capecitabine and doxorubicin. Global uncertainty is below 35% for concentrations above 100 pg/cm² (except for capecitabine and doxorubicin)-a guidance value for relevant contamination. Method application in a Portuguese university hospital (28 samples) identified the presence of seven cytostatics, at concentrations below 100 pg/cm², except for three samples. The widespread presence of cyclophosphamide evinces the necessity to review implemented procedures.

Validation of chemotherapy drug vapor containment of an air cleaning closed-system drug transfer device

PURPOSE

The purpose of this study was to test the efficacy of ChemfortTM, an air filtration closed-system drug transfer device to prevent release of chemotherapy drug vapors and aerosols under extreme conditions. The air cleaning system is based on the adsorption of drug vapors by an activated carbon filter in the Vial Adaptor before the air is released out of the drug vial. The functionality of the carbon filter was also tested at the end of device's shelf life, and after a contact period with drug vapors for 7 days. Cyclophosphamide and 5-fluorouracil were the chemotherapy drugs tested.

METHODS

The Vial Adaptor was attached to a drug vial and both were placed in a glass vessel. A needle was punctured through the vessel stopper and the Vial Adaptor septum to allow nitrogen gas to flow into the vial and to exit the vial via the air filter into the glass vessel which was connected to a cold trap. Potential contaminated surfaces in the trap system were wiped or rinsed to collect the escaped drug. Samples were analyzed using liquid chromatography tandem mass spectrometry.

RESULTS

Cyclophosphamide and 5-fluorouracil were detected on most surfaces inside the trap system for all Vial Adaptors without an activated carbon filter. Contamination did not differ between the Vial Adaptors with and without membrane filter indicating no effect of the membrane filter. The results show no release of either drug for the Vial Adaptors with an activated carbon filter even after 3 years of simulated aging and 7 days of exposure to drug vapors.

CONCLUSIONS

Validation of air cleaning CSTDs is important to secure vapor and aerosol containment of chemotherapy and other hazardous drugs. The presented test method has proven to be appropriate for the validation of ChemfortTM Vial Adaptors. No release of cyclophosphamide and 5- fluorouracil was found even for Vial Adaptors after 3 years of simulated aging and 7 days of exposure to drug vapors.

Perception of risk of exposure in the management of hazardous drugs in home hospitalization and hospital units

OBJECTIVE

To assess the perception of risk of exposure in the management of hazardous drugs (HDs) through home hospitalization and hospital units.

MATERIAL AND METHODS

A questionnaire was released, at the national level, to health professionals with HD management expertise. Questionnaire included 21 questions that were scored using a Likert scale: 0 (null probability) to 4 (very high probability). The internal consistency and reliability of the questionnaire were calculated using Cronbach's alpha and the intraclass correlation coefficient, respectively.

RESULTS

144 questionnaires (response rate 70.2%) were obtained: 65 (45.1%) were nurses, 42 (28.9%) occupational physicians, and 37 (26.1%) were pharmacists. Cronbach's alpha was 0.93, and intraclass correlation coefficient was 0.94 (95% CI 0.91-0.97; p-value < 0.001). The mean probability was 1.95 ± 1.02 (median 1.9; minimum: 0.05; 1st quartile 1.1; 3rd quartile 2.6; and maximum 4). Differences were observed in scoring among professional groups (occupational physicians versus nurses (1.6/2.1, p = 0.044); pharmacists versus nurses (1.7/2.1, p = 0.05); and occupational physicians versus pharmacists (1.6/1.7, p = 0.785), due mainly to the administration stage (p = 0.015).

CONCLUSIONS

The perception of risk of exposure was moderate, being higher for nurses. It would be advisable to integrate HDs into a standardized management system (risk management model applicable to any healthcare center) to improve the safety of health professionals.

Cytostatics in Indoor Environment: An Update of Analytical Methods

Periodic and adequate environmental monitoring programs are crucial to assess and reduce the occupational exposure of healthcare workers to cytostatics. The analytical methods employed should be rapid, reliable, sensitive, standardized, and include multiple compounds. A critical overview of recent overall procedures for surface and air contamination with cytostatics in workplace settings is presented, with a focus on sampling, sample preparation, and instrumental considerations. Limitations are also addressed and some recommendations and advice are provided. Since dermal absorption is the main exposure route, surface contamination is the preferred indicator of biological uptake and its methods have significantly improved. In contrast, cytostatics’ inhalation is rare; thus, air contamination has been poorly studied, with little improvement. Still, some elements of the analytical methods have not been extensively explored, namely: the amount of wetting solution, the extraction procedure, surface chemistry and roughness, recovery studies from specific surfaces, and cytostatics stability (in surfaces and during shipping and storage). Furthermore, complete validation data (including precision, accuracy, and instrumental and method detection limits) and estimation of global uncertainty are still lacking in most studies, thus preventing method comparison and proposal of standardized procedures.

Bundle for the prevention and management of complications of neutropenia in cancer patients

OBJECTIVES

to construct and assess bundle content for the prevention and management of complications in neutropenia in cancer patients.

METHODS

a methodological study developed in four stages: scoping review; bundle construction; material assessment by experts (developed according to Pasquali's psychometry); pilot test in a High Complexity Assistance Unit in Oncology. For content assessment, the Delphi technique was applied in two rounds and those items with Content Validation Coefficient (CVC)> 0.78 and agreement> 80.0% were considered valid. Data were analyzed using descriptive and inferential statistics.

RESULTS

all bundle requirements reached agreement between judges above 80.0%, in addition to statistically significant levels of assessment. At the end of the Delphi technique, bundle was significantly valid with CVC = 0.92 and CVC = 0.93, respectively.

CONCLUSIONS

bundle content proved to be valid and highly credible.

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.

Threat and sustainable technological solution for antineoplastic drugs pollution: Review on a persisting global issue

In the past 20 years, the discharge of pharmaceuticals and their presence in the aquatic environment have been continuously increasing and this has caused serious public health and environmental concerns. Antineoplastic drugs are used in chemotherapy, in large quantities worldwide, for the treatment of continuously increasing cancer cases. Antineoplastic drugs also contaminate water sources and possess mutagenic, cytostatic and eco-toxicological effects on microorganisms present in the aquatic environment as well as on human health. Due to the recalcitrant nature of antineoplastic drugs, the commonly used wastewater treatment processes are not able to eliminate these drugs. Globally, various anticancer drugs are being consumed during chemotherapy in hospitals and households by out-patients. These anti-cancer agents enter the water bodies in their original form or as metabolites via urine and faeces of the out-patients or the patients admitted in hospitals. Due to its high lipid solubility, the antineoplastic drugs accumulate in the fatty tissues of the organisms. These drugs enter through the food chain and cause adverse health effects on humans due to their cytotoxic and genotoxic properties. The United States Environmental Protection Agency (US-EPA) and the Organization for Economic Cooperation and Development (OECD) elucidated new regulations for the management of hazardous pharmaceuticals in the water environment. In this paper, the role of antineoplastic agents as emerging water contaminants, its transfer through the food chain, its eco-toxicological properties and effects, technological solutions and management aspects were reviewed.

Pelvic floor: vaginal or caesarean delivery? A review of systematic reviews

INTRODUCTION AND HYPOTHESIS

In recent years the number of caesarean sections has increased worldwide for different reasons. to review the scientific evidence relating to the impact of the type of delivery on pelvic floor disorders (PFDs) such as urinary and faecal incontinence and pelvic organ prolapse.

METHODS

A review of systematic reviews and meta-analysis, drawn from the following databases: MEDLINE (via PubMed), Scopus, Web of Science, The Cochrane Library and LILACS (Literatura Latinoamericana y del Caribe en Ciencias de la Salud/Latin American and Caribbean Health Sciences Literature) prior to January 2019. The directives of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses were used in assessing article quality.

RESULTS

Eleven systematic reviews were evaluated, 6 of which found a significantly decreased risk of urinary incontinence associated with caesarean section and 3 meta-analyses showed a significant reduction in POP for caesarean section, compared with vaginal delivery. Of 5 reviews that examined delivery type and faecal incontinence, only one indicated a lower incidence of faecal incontinence associated with caesarean delivery. However, most of the studies included in these reviews were not adjusted for important confounding factors and the risk of PFDs was not analysed by category of caesarean delivery (elective or urgent).

CONCLUSION

When compared with vaginal delivery, caesarean is associated with a reduced risk of urinary incontinence and pelvic organ prolapse. These results should be interpreted with caution and do not help to address the question of whether elective caesareans are protective of the maternal pelvic floor.

Inhaled cytotoxic chemotherapy: clinical challenges, recent developments, and future prospects

INTRODUCTION

Since 1968, inhaled chemotherapy has been evaluated and has shown promising results up to phase II but has not yet reached the market. This is due to technological and clinical challenges that require to be overcome with the aim of optimizing the efficacy and the tolerance of drug to re-open new developments in this field. Moreover, recent changes in the therapeutic standard of care for treating the patient with lung cancer also open new opportunities to combine inhaled chemotherapy with standard treatments.

AREAS COVERED

Clinical and technological concerns are highlighted from the reported clinical trials made with inhaled cytotoxic chemotherapies. This work then focuses on new pharmaceutical developments using dry powder inhalers as inhalation devices and on formulation strategies based on controlled drug release and with sustained lung retention or based on nanomedicine. Finally, new clinical strategies are described in regard to the impact of the immunotherapy on the patient's standard of care.

EXPERT OPINION

The choice of the drug, inhalation device, and formulation strategy as well as the position of inhaled chemotherapy in the patient's clinical care are crucial factors in optimizing local tolerance and efficacy as well as in its scalability and applicability in clinical practice.

Occupational health and safety hazards faced by healthcare professionals in Taiwan: A systematic review of risk factors and control strategies

Background

Healthcare professionals in Taiwan are exposed to a myriad of occupational health and safety hazards, including physical, biological, chemical, ergonomic, and psychosocial hazards. Healthcare professionals working in hospitals and healthcare facilities are more likely to be subjected to these hazards than their counterparts working in other areas.

Objectives

This review aims to assess current research literature regarding this situation with a view to informing policy makers and practitioners about the risks of exposure and offer evidence-based recommendations on how to eliminate or reduce such risks.

Methods

Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses review strategy, we conducted a systematic review of studies related to occupational health and safety conducted between January 2000 and January 2019 using MEDLINE (Ovid), PubMed, PMC, TOXLINE, CINAHL, PLOS One, and Access Pharmacy databases.

Results

The review detected 490 studies addressing the issue of occupational health and safety hazards; of these, 30 articles were included in this systematic review. These articles reported a variety of exposures faced by healthcare professionals. This review also revealed a number of strategies that can be adopted to control, eliminate, or reduce hazards to healthcare professionals in Taiwan.

Conclusion

Hospitals and healthcare facilities have many unique occupational health and safety hazards that can potentially affect the health and performance of healthcare professionals. The impact of such hazards on healthcare professionals poses a serious public health issue in Taiwan; therefore, controlling, eliminating, or reducing exposure can contribute to a stronger healthcare workforce with great potential to improve patient care and the healthcare system in Taiwan. Eliminating or reducing hazards can best be achieved through engineering measures, administrative policy, and the use of personal protective equipment.

Implications

This review has research, policy, and practice implications and provides future students and researchers with information on systematic review methodologies based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses strategy. It also identifies occupational health and safety risks and provides insights and strategies to address them.

Analyse de minimisation de coût des fournitures utilisées pour la préparation et l’administration d’une dose d’antinéoplasique en établissement de santé

BACKGROUND

Many strategies aim to reduce the risk of work-related exposure to hazardous drugs for health care workers; these strategies include the use of specific systems to prepare and administer these drugs.

OBJECTIVE

To compare the cost of supplies used for preparing and administering one IV dose of antineoplastic in an adult health care facility in Canada between the traditional approach and one using a closed-system drug transfer device (CSTD).

METHOD

This study was a cost reduction analysis conducted from the perspective of a typical university health care facility. The assessment focused only on the cost of supplies used to prepare and administer one IV dose of antineoplastic. It was not necessary to account for discounting. We developed 12 scenarios involving some of the 11 possible steps in preparing and administering one IV dose of antineoplastic.

RESULTS

The cost of supplies used to prepare and administer one IV dose of antineoplastic ranged between $9.89 and $22.37 per dose with the classical system, and between $12.34 and $64.19 per dose for systems involving a CSTD. The annual average extra cost of systems involving a CSTD was 1.63 to 3.15 higher than the cost with the classical system and represents extra spending of between $363 566 and $1 238 072 each year for a typical adult health care institution.

CONCLUSION

This cost reduction analysis presents original data relating to the preparation and administration of IV antineoplastics. Given the significant costs associated with preparing and administering antineoplastic drugs, decision-makers should perform a thorough analysis of costs and consequences to allow informed decisions to be made.

Compliance and Adherence to Enteral Nutrition Treatment in Adults: A Systematic Review

Objective: To review the scientific literature that has verified and/or assessed compliance and adherence to enteral nutrition (EN) in adult patients. Method: This study involved a critical analysis of articles retrieved from MEDLINE (PubMed), The Cochrane Library, Embase, Scopus and Web of Science using the terms “Treatment Adherence and Compliance” and “Enteral Nutrition”, applying the filters “Comparative Study” or “Clinical Trial”, “Humans” and “Adults”. Date of the search: 25 October 2018. Results: A total of 512 references were retrieved, of which 23 documents were selected after applying the inclusion and exclusion criteria. The techniques measuring adherence to EN were determined by dietary intake, self-reporting, counts of leftover containers or presence of complications; however, in no case were validated questionnaires used. The time and periodicity of the assessment presented very heterogeneous results, with measurement predominantly being done at the beginning and at the end of the study. The best adherence rates were obtained in hospitalized patients (approximately 80%). Conclusions: Frequent and regular monitoring of the adherence of patients under prolonged treatment with EN is necessary, and the use of measurement techniques that allow obtaining information on the causes of non-adherence facilitates early interventions to optimize treatment outcomes. Patient and/or caregiver education in the management of EN and the intervention of the community pharmacy in monitoring patients can be key to improving the adherence to EN.

A Pattern Based Method for Simplifying a BPMN Process Model

BPMN (Business Process Model and Notation) is currently the preferred standard for the representation and analysis of business processes. The elaboration of these BPMN diagrams is usually carried out in an entirely manual manner. As a result of this human-driven process, it is not uncommon to find diagrams that are not in their most simplified version possible (regarding the number of elements). This work presents a fully automatic method to simplify a BPMN process model document. A two-phase iterative algorithm to achieve this simplification is described in detail. This algorithm follows a heuristic approach that makes intensive use of a Pattern Repository. This software element is concerned with the description of feasible reductions and its enactment. The critical concept lies in the discovery of small reducible patterns in the whole model and their substitution with optimised versions. This approach has been verified through a double validation testing in total 8102 cases taken from real world BPMN process models. Details for its implementation and usage by practitioners are provided in this paper along with a comparison with other existing techniques concerned with similar goals.

PATIENT SAFETY IN THE ADMINISTRATION OF ANTINEOPLASTIC CHEMOTHERAPY AND OF IMMUNOTHERAPICS FOR ONCOLOGICAL TREATMENT: SCOPING REVIEW

ABSTRACT Objective: to identify and synthesize the scientific evidence on cancer patient safety in the administration of antineoplastic and immunotherapeutic chemotherapeutic agents. Method: a scoping review, according to the Joanna Briggs Institute and to the recommendations of the PRISMA-ScR international guide. The research was conducted in five electronic databases, the Cochrane Library and eight catalogs of theses and dissertations. The inclusion criteria were the following: studies related to patient safety in the administration of antineoplastic and immunotherapeutic chemotherapy by nurses in places where cancer care occurs, published entirely in Portuguese, Spanish and/or English, with no time limit. The extracted data were analyzed and synthesized in narrative form. Results: a total of 14,444 records were retrieved and 47 studies were kept for review. Most publications (44.7%) had a qualitative approach, while 40.4% were quantitative and 14.9%, mixed. When summarizing the findings, the following themes emerged: Safety standards in parenteral administration of antineoplastic chemotherapy; Good practices for patient safety using oral antineoplastic therapy; Administration and safe handling of immunotherapies; Prevention and management of errors related to the administration of antineoplastic and immunotherapeutic chemotherapeutic agents. Conclusion: patients safety with cancer in the administration of antineoplastic therapy occurs when there is implementation of evidence-based protocols, continuing education of nurses and implementation of safety standards and processes, as a strategy to prevent errors in drug administration.

A BPMN Based Notation for the Representation of Workflows in Hospital Protocols

Flowcharts used for hospital protocols have a series of ambiguities and limitations in order to express some types of information. In this article, a notation proposal for flowcharts that partially avoids these problems is presented. This new notation is an adaptation of BPMNE2, an extension of the Business Process Model and Notation (BPMN), which allows direct modelling of procedures that follow the Hazard Analysis and Critical Control Points (HACCP) model. The new notation has been validated in the hospital context, specifically in the field of hazardous drugs (HDs). To measure usability from the perspective of the health staff and auditors, the System Usability Scale (SUS) was used. A total of 47 experts took part in the assessment, resulting in a SUS score of 71, that corresponds to an acceptable level of usability. The feedback provided by these participants allows us to discover benefits and drawbacks of the proposal. Also, it is noteworthy that 76.6% of professionals prefer to migrate to the new notation from the ISO 5807:1985 notation, the most commonly used model. In addition to the direct benefits of this notation from the human point of view, its machine-understandable nature provides the required support for its integration into software tools for intelligent monitoring and auditing.
