Incidents et accidents médicamenteux en établissement de santé : une analyse descriptive au sein d'un CHU mère-enfant de 2018 à 2022.

Background: The safety of care provided is based on an analysis of medication incidents and accidents. Objective: The primary objective was to describe medication-related incidents and accidents (I&A) within a university-affiliated hospital. Methods: This retrospective descriptive study was based on data from a 500-bed mother-child university-affiliated hospital. All I&As declared between April 1, 2018, and March 31, 2022, were considered. The analysis included all medication-related I&As that occurred during an admission or in an outpatient setting. Some variables were recoded manually. Descriptive statistical analyses were performed. Results: A total of 23 284 I&As were considered, including 7578 medication-related I&As. Daily averages of 15.9 ± 14.0 I&As and 5.2 ± 0.3 medication-related I&As were reported. There were 22.4 medication-related I&As/1000 inpatient days. The majority of medication-related I&As occurred in surgery (20%, 1530/7578), oncology (19%, 1405/7578), and pediatrics (16%, 1200/7578). Most were associated with incorrect dosing (21%, 1575/7578); infiltration, extravasation, or removed lines (19%, 1405/7578); and omissions (16%, 1205/7578). Physical consequences were reported in 15% (1158/7578) of the medication-related I&As. Conversely, psychological consequences were reported in less than 1% (44/7578) of medication-related I&As. Conclusions: This study provides a comprehensive descriptive profile over a 4-year period. Most of the reported I&As did not lead to consequences for patients. The sharing of ratios promotes comparative analysis with other facilities and can contribute to discussions about risk reduction. A culture of reporting events is present within this health care facility.

Ratios d'incidents et d'accidents totaux et médicamenteux par 1000 jours-présence en établissement de santé au Québec: une étude exploratoire.

Background: Since 2022, it has been mandatory in Québec to report all incidents and accidents (I&As) occurring in health-care facilities. Since 2011, a summary report of these I&As has been published each year. However, it is difficult to compare health facilities given that no denominator is specified and ratios are not calculated. Objective: The primary objective was to calculate the ratios of total I&As and medication-related I&As per 1000 inpatient-days per type of facility for all health-care facilities in Québec. Methods: This retrospective descriptive study was based on data from the period of April 1, 2016, to March 31, 2021. Data were extracted from the National Register of Incidents and Accidents Occurring during the Provision of Health Care and Social Services in Québec (Registre national des incidents et accidents survenus lors de la prestation des soins et services de santé au Québec) and financial reports. The ratios of total I&As/1000 inpatient-days and medication-related I&As/1000 inpatient-days, expressed as the mean ± standard deviation and median [minimum; maximum], were calculated. Results: A total of 85 health-care facilities had usable data, specifically 33 acute-care facilities, 45 long-term care facilities, and 7 rehabilitation facilities. The mean ratio for total I&As/1000 inpatient-days varied from 33 ± 19 to 38 ± 22 in acute-care facilities, from 14 ± 5 to 16 ± 7 in long-term care facilities, and from 99 ± 39 to 147 ± 55 in rehabilitation facilities. The mean ratio for medication-related I&As/1000 inpatient-days varied from 11 ± 7 to 12 ± 7 in acute care facilities, from 3 ± 2 to 4 ± 3 in long-term care facilities, and from 24 ± 10 to 40 ± 21 in rehabilitation facilities. Conclusions: This exploratory study demonstrated the feasibility of calculating I&A ratios from the National Register of Incidents and Accidents Occurring during the Provision of Health Care and Social Services in Québec. These ratios facilitate discussion of the reporting culture of I&As within the health-care system. It is hoped that these ratios will be added to future annual reports from the Québec I&A register.

[Evaluation of pharmaceutical practice in hospitals: An exploratory study comparing processes in France and Quebec]. / Évaluation de la pratique pharmaceutique en établissement de santé : une étude exploratoire comparant les processus en France et au Québec.

CONTEXT: To ensure compliance with the legal and normative framework, the professional orders, which supervise the practice of pharmacy have established a professional inspection process. In addition to this process, other external organizations also require an accreditation, authorization, certification or validation process for professional practices. OBJECTIVE: The main objective is to identify and compare the methods of evaluating pharmaceutical practice in hospitals in France and Quebec. RESULTS: In order to identify and compare the methods of evaluating pharmaceutical practice in hospitals in France and Quebec, our approach allowed us to identify more organizations in France (i.e., High Authority of Health, Regional Health Agencies, the National Order of Pharmacists, the Nuclear Safety Agency, the Biomedicine Agency and the National Agency for the Safety of Medicines and Health Products) than in Quebec (i.e., Accreditation Canada, Ordre des pharmaciens du Québec and Health Canada). The study highlights the legal framework and applicable standards, the surveyors, the evaluation methods and the particularities for the evaluation of the hospital, the pharmacy department and the members of the department. CONCLUSIONS: This study highlights the evaluation processes of pharmaceutical practice in hospitals. In France, as in Quebec, we recognize the importance of the drug circuit in the hospital, the development and operation of a pharmacy department and the practice of pharmacy. While there are more similarities for the assessment of the drug circuit in hospitals and pharmacy department, important differences are observed for the assessment of individuals. We believe that the publication of a comparative analysis can contribute to discussions and exchanges to benefit from the best practices of each country.

Disponibilité de l'information médicale requise pour la déclaration d'une réaction indésirable médicamenteuse à Santé Canada: une étude exploratoire.

Background: Since 2019, health care facilities have been required to report serious adverse drug reactions (ADRs) to Health Canada. Objectives: To describe the availability of information required for reporting an ADR to Health Canada from medical records using 2 methods (systematic and in-depth reporting) and to compare the time required to find the information. Methods: This retrospective and prospective descriptive study involved serious ADRs occurring in a mother-child centre and reported between April 1, 2021, and March 31, 2023. The variables needed to complete the Health Canada reporting form were collected using 2 distinct methods. Results: Among the 270 serious ADRs reported retrospectively, 140 were sampled. The average availability of variables was 82.3% (standard deviation [SD] 11.3%), with average data collection time of 50 (SD 25) minutes. For the prospective part of the study, 15 serious ADRs were studied. The availability of variables was 82.8% (SD 6.9%) and 91.9% (SD 7.8%), for systematic and in-depth reporting, respectively, with data collection times of 44 (SD 17) and 130 (SD 33) minutes, respectively. Conclusions: The challenge of finding, in patients' medical records, all of the information needed for reporting an ADR to Health Canada required an in-depth approach. However, the in-depth method took 3 times as long as a search limited to places in the record where specific information should be found. To improve record keeping, additional training for clinicians could be considered and, potentially, development of a computerized clinical record that includes a dedicated form for documenting ADRs.

Contexte: Depuis 2019, les établissements de santé doivent déclarer les réactions indésirables graves aux médicaments (RIM graves) à Santé Canada. Objectifs: Décrire la disponibilité de l'information requise pour la déclaration d'une RIM à Santé Canada dans les dossiers médicaux par deux méthodes (soit, systématique et approfondie) et comparer le temps nécessaire pour retrouver l'information. Méthode: Étude descriptive rétrospective et prospective des RIM graves survenues en centre mère-enfant et déclarées entre le 1er avril 2021 et 31 mars 2023. Les variables nécessaires pour remplir le formulaire de déclaration de Santé Canada ont été collectées par deux méthodes distinctes. Résultats: Parmi les 270 RIM graves déclarées en rétrospectif, 140 ont été échantillonnées. La disponibilité moyenne des variables était de 82,3 % (écart-type [SD] 11,3 %), pour une durée de collecte de 50 (SD 25) minutes. Du côté prospectif, 15 RIM graves ont été étudiées, la disponibilité des variables était, pour chacune des méthodes respectivement, de 82,8 (SD 6,9 %) et 91,9 (SD 7,8 %), pour des temps de collecte respectifs de 44 (SD 17) et 130 (SD 33) minutes. Conclusions: La difficulté que représente l'identification de toutes les informations requises dans les dossiers médicaux pour la déclaration d'une RIM à Santé Canada nécessite une recherche approfondie. Toutefois, la recherche approfondie demande trois fois plus de temps qu'une recherche qui se limiterait aux endroits où l'information devrait se retrouver. Il est possible d'envisager de dispenser une formation supplémentaire aux cliniciens pour améliorer la tenue de dossiers et, éventuellement, le recours à un dossier clinique informatisé qui comprend un formulaire dédié à la documentation des RIM.

Two-year audit of compliance in the preparation and administration of medications by nursing staff in a mother-and-child university hospital center.

OBJECTIVE: Audits are essential for reviewing and improving the medication-use process. Identifying areas for improvement can limit the risk of errors when preparing and administering drugs. Pediatric centers face specific challenges in ensuring the safety of the medication-use process. The objective of this study was to observe and compare compliance with criteria for the preparation and administration of medications by nurses in a mother-and-child university hospital center over two consecutive years. METHODS: This observational cross-sectional study was conducted in a Canadian mother-and-child university hospital center. Audits were conducted over a 1-month period in 16 and 18 nursing care sectors in 2021 and 2022, respectively. The standardized audit evaluated compliance with prespecified criteria related to the preparation and administration of medication by nursing staff (77 criteria for 2021 and 82 criteria for 2022). The auditors comprised nurses and a pharmacist trained by the research team. Compliance was compared between years and assessed through a chi-square test. RESULTS: The audit consisted of 522 observations in 2021 and 448 observations in 2022. Overall compliance was 76% in 2021 and 66% in 2022. The compliance rate by criterion ranged from 16% to 100%. In 2021 and 2022, 51 (84%) and 52 (87%) of the criteria, respectively, had compliance rates of more than 75%, and 12 (20%) and eight (13%), respectively, had 100% compliance. There were statistically significant decreases in compliance for nine of the 39 criteria for preparation of medications, notably prior hand hygiene (91%% vs. 84%, p = 0.002), and for six of the 17 criteria for administration of medications, including mentioning possible adverse effects to the patient (41% vs- 30%, p = 0.008). CONCLUSION: In this study, compliance was over 75% for most of the criteria. However, for a few criteria, we observed a decrease in compliance from 2021 to 2022. Various hypotheses are proposed to explain these decreases, such as the COVID-19 pandemic.

Canadian monitoring program of the surface contamination with 11 antineoplastic drugs in 124 centers.

INTRODUCTION: Occupational exposure to antineoplastic drugs can lead to long-term adverse effects on workers' health. A reproducible Canadian surface monitoring program was established in 2010. The objective was to describe contamination with 11 antineoplastic drugs measured on 12 surfaces among hospitals participating in this annual monitoring program. METHODS: Each hospital sampled six standardized sites in oncology pharmacies and six in outpatient clinics. Ultra-performance liquid chromatography coupled with tandem mass spectrometry was used for cyclophosphamide, docetaxel, doxorubicin, etoposide, 5-fluorouracil, gemcitabine, irinotecan, methotrexate, paclitaxel, and vinorelbine. Platinum-based drugs were analyzed by inductively coupled plasma mass spectrometry; this excludes inorganic platinum from the environment. Hospitals filled out an online questionnaire about their practices; a Kolmogorov-Smirnov test was used for some practices. RESULTS: One hundred and twenty-four Canadian hospitals participated. Cyclophosphamide (405/1445, 28%), gemcitabine (347/1445, 24%), and platinum (71/756, 9%) were the most frequent. The 90th percentile of surface concentration was 0.01 ng/cm² for cyclophosphamide and 0.003 ng/cm² for gemcitabine. Centers that prepared 5000 or more antineoplastic per year had higher concentrations of cyclophosphamide and gemcitabine on their surfaces (p = 0.0001). Almost half maintained a hazardous drugs committee (46/119, 39%), but this did not influence the cyclophosphamide contamination (p = 0.051). Hazardous drugs training was more frequent for oncology pharmacy and nursing staff than for hygiene and sanitation staff. CONCLUSIONS: This monitoring program allowed centers to benchmark their contamination with pragmatic contamination thresholds derived from the Canadian 90th percentiles. Regular participation and local hazardous drug committee involvement provide an opportunity to review practices, identify risk areas, and refresh training.

National survey of safe handling of hazardous drugs in hospital settings: Use of an innovative approach.

INTRODUCTION: Workers can reduce their risk of exposure to hazardous drugs by following safe handling guidelines. Healthcare centers need to dedicate time and resources in order to implement new safety recommendations. The objective was to present the results of a national survey about the safe handling of hazardous drugs in healthcare centers. METHODS: Quebec healthcare centers performed an auto-evaluation to the newly updated safe handling guidelines in 2021. Centers rated each criterion as compliant or non-compliant. The guidelines tailored recommendations according to three categories of hazards: G1, consisting mostly of carcinogenic drugs; G2, other hazardous drugs; and G3, those with reproductive toxicity. The questionnaire prompted participants to document their planned corrective measures for non-compliant criteria. RESULTS: Most centers participated (28/29, 97%). The overall compliance was 58% (8761/15,216 criteria). The conformity per theme was hygiene and sanitation (1290/1,878, 69%), laundry (221/367, 60%), pharmacy (2658/4,474, 59%), nursing (3436/6,017, 57%), spills and accidental exposure (353/649, 54%), and general measures (803/1,831, 44%). It was higher for recommendations regarding G1s (4226/6,115, 69%) than for G2s (1626/3557, 46%) and G3s (372/916, 41%). CONCLUSIONS: This project successfully used an innovative approach that combined a national auto-evaluation survey, an actionable report, and the involvement of a community of practice. Centers were able to benchmark their implementation of safe handling guidelines, and community of practices may help in sharing the best practices. The design of the questionnaire helped in targeting corrective measures. More work is needed for safe handling practices that relate to G2 and G3 drugs.

Training workload in the investigational drug service of a university hospital center.

PURPOSE: Training represents a considerable portion of research activities and is vastly different for each clinical trial. This variation is partially explained by the lack of detailed regulations surrounding training procedures, which hinders the ability of investigational drug service (IDS) staff to plan their workload. The aim of this study was to quantify the workload associated with trial-specific training of IDS staff. The secondary aim was to identify the factors associated with training complexity. METHODS: A retrospective study was carried out in the IDS of a mother and child university hospital. Trial-specific documents on which the pharmacy staff was trained were analyzed. Workload was calculated by measuring reading time. The readability of each document was determined by the Flesch Reading Ease score. The complexity of the trials was established using the scoring method of Calvin-Lamas et al. The influence of the following factors on training was assessed by analysis of variance: sponsor type, research phase, and research focus by medical specialty. RESULTS: A total of 93 clinical trials and 433 documents were included. Investigator's brochures were the longest (a mean [SD] of 107 [46] pages; P < 0.0001) and most difficult documents to read (mean [SD] readability score, 25.5 [4.4]; P < 0.0001). Trials with industry sponsors required a significantly longer overall reading time (mean [SD], 12.26 [6.72] hours; P < 0.0001). On average, a mean (SD) of 9.42 (7.16) hours of reading were necessary to train one employee for a clinical trial. CONCLUSION: This study is the first to document reading time necessary for training of IDS staff. The training workload varied by sponsor type, while the research phase and medical specialty had little impact. IDS units would benefit from a tool that could identify complex trials.

Assessment of adherence to at-home oral anti-infective therapy among paediatric patients discharged from a Quebec hospital.

OBJECTIVES: Non-adherence to anti-infective therapy contributes to treatment failure and the emergence of bacterial resistance. This study aimed to assess at-home adherence, by paediatric patients, to oral anti-infective (OAI) therapy prescribed for treatment of acute infections and to explore the factors contributing to non-adherence. METHODS: This prospective descriptive study involved French-speaking patients under 16 years of age who were discharged with one or more OAIs prescribed for home administration for a maximum of 30 days. Telephone surveys were used to assess overall adherence, which consisted of primary adherence (patient's ability to procure the medication) and secondary adherence (patient's ability to take the treatment as prescribed). RESULTS: Overall, 51.7% (30/58) of patients were adherent to OAI therapy, with 100% primary adherence (n=69/69) and 51.7% secondary adherence (n=30/58). On average, patients took 98% of the total number of doses prescribed, and non-adherence was related mostly to not following medication administration schedules (63.3% of patients followed the exact schedule). Indeed, the adherence rate for patients taking one or two doses per day was twice the rate for patients taking more than two doses per day (81.8% vs 44.7%, p=0.043). CONCLUSIONS: Half of the paediatric patients treated for acute infections were non-adherent to OAI therapy at home. Interventions are needed to improve this situation.

Canadian monitoring program of the surface contamination with 11 antineoplastic drugs in 122 centers.

INTRODUCTION: Occupational exposure to antineoplastic drugs can lead to long-term adverse effects on workers' health. Environmental monitoring is conducted once a year, as part of a Canadian monitoring program. The objective was to describe contamination with 11 antineoplastic drugs measured on surfaces. METHODS: Six standardized sites in oncology pharmacy and six in outpatient clinic were sampled in each hospital. Samples were analyzed by ultra-performance liquid chromatography coupled with tandem mass spectrometry (non-platinum drugs) and by inductively coupled plasma mass spectrometry (platinum-based drugs). The limits of detection (in ng/cm2) were: 0.0006 for cyclophosphamide; 0.001 for docetaxel; 0.04 for 5-fluorouracil; 0.0004 for gemcitabine; 0.0007 for irinotecan; 0.0009 for methotrexate; 0.004 for paclitaxel, 0.009 for vinorelbine, 0.02 for doxorubicine, 0.0037 for etoposide and 0.004 for the platinum. Sub-analyses were done with a Kolmogorov-Smirnov test. RESULTS: 122 Canadian hospitals participated. Cyclophosphamide (451/1412, 32% of positive samples, 90th percentile of concentration 0.0160 ng/cm2) and gemcitabine (320/1412, 23%, 0.0036 ng/cm2) were most frequently measured on surfaces. The surfaces most frequently contaminated with at least one drug were the front grille inside the biological safety cabinet (97/121, 80%) and the armrest of patient treatment chair (92/118, 78%).The distribution of cyclophosphamide concentration was higher for centers that prepared ≥ 5000 antineoplastic drug preparations/year (p < 0.0001). CONCLUSIONS: This monitoring program allowed centers to benchmark their contamination with pragmatic contamination thresholds derived from the Canadian 90th percentiles. Problematic areas need corrective measures such as decontamination. The program helps to increase the workers' awareness.

Design and Development of an Escape Game as a Knowledge Transfer Tool in Preparation for an Accreditation Visit in a Health Care Facility.

Background: Knowledge transfer helps health care staff to be competent, well informed, and up to date. It also contributes to adherence to standards and best practices. Objectives: To design, implement, and evaluate an escape game based on a selection of Accreditation Canada required organizational practices (ROPs). Methods: This prospective descriptive study involved nurses and pharmacists in a health care centre. An escape game based on 6 ROPs was designed. The game was played by teams of participants in a patient room within the centre, with each game lasting 25 minutes. Participants' satisfaction with various aspects of their experience was assessed. Results: A total of 200 people (52 teams) participated in the escape game. About half of the teams (n = 28) completed the game within the allotted time (average completion time 20 minutes, 53 seconds; standard deviation [SD] 2 minutes, 45 seconds). On average, 1.32 (SD 0.88) clues were provided to successful teams and 1.88 (SD 0.95) to unsuccessful teams. Participants were very satisfied with their experience. However, members of unsuccessful teams had significantly lower agreement that the escape game was relevant to their practice and that it was an effective method of communication. Conclusions: An escape game based on a selection of ROPs was successfully implemented as part of the hospital's preparation for an accreditation visit. Use of an escape game as a knowledge transfer tool was appreciated by the staff.

Contexte: La transmission des connaissances aide le personnel de la santé à être compétent, bien informé et à jour. Elle contribue également au respect des normes et des meilleures pratiques. Objectifs: Concevoir, mettre en œuvre et évaluer un jeu d'évasion basé sur une sélection de pratiques organisationnelles requises (POR) d'Agrément Canada. Méthodes: Des infirmiers et des pharmaciens d'un centre de santé ont participé à cette étude prospective descriptive. Un jeu d'évasion basé sur 6 POR a été conçu. Des équipes de participants y ont joué dans une chambre de patient au sein du centre, chaque partie durant 25 minutes. La satisfaction des participants à l'égard de divers aspects de leur expérience a été évaluée. Résultats: Au total, 200 personnes (52 équipes) y ont participé. Environ la moitié des équipes (n = 28) ont terminé le jeu dans le temps imparti (temps moyen d'achèvement 20 minutes, 53 secondes ; écart type [ET] 2 minutes, 45 secondes). En moyenne, 1,32 indice (ET 0,88) a été remis aux équipes qui l'ont réussi et 1,88 (ET 0,95) aux équipes qui ont échoué. Les participants étaient très satisfaits de leur expérience. Cependant, les membres des équipes ayant échoué étaient significativement moins d'accord sur le fait que le jeu d'évasion était pertinent pour l'exercice de leur profession et qu'il s'agissait d'une méthode de communication efficace. Conclusions: Un jeu d'évasion basé sur une sélection de POR a été mis en place avec succès dans le cadre de la préparation de l'hôpital à une visite d'agrément. L'utilisation d'un jeu d'évasion comme outil de transmission des connaissances a été reçue de manière positive par le personnel.

Exploration de l'association possible entre la consommation d'antibiotiques et l'émergence de résistance dans un centre hospitalier universitaire mère-enfant.

Background: The emergence of antibiotic resistance has contributed to the development of multidrug-resistant bacteria, which is a major concern. Objectives: The primary objective was to explore the possible association between antibiotic use and the emergence of resistance in a mother-child university hospital. Method: This retrospective study was conducted in a university hospital centre. Antibiotic-bacteria pairs were established, taking into account the number of isolates, actual antibiotic use, and clinical relevance. For each pair, a comparison of 2 variables (antibiotic utilization and rate of resistance) was quantified with the Pearson coefficient. Three analyses were conducted: no lag between utilization and resistance, 1-year lag, and 2-year lag. Results: Thirty antibiotic-bacteria pairs were selected from hematology-oncology and 18 from neonatology. In hematology-oncology, 6 pairs had a positive correlation (Pearson coefficient > 0.7): 2 pairs involving meropenem, 2 involving ceftazidime, and 2 involving piperacillin-tazobactam. In 3 of these cases, there was no lag between consumption of antibiotics and presence of resistance. In neonatology, 3 antibiotic-bacteria pairs had a positive correlation, 1 each involving vancomycin, cloxacillin, and meropenem. Conclusions: It is possible to explore the potential association between consumption of antibiotics and emergence of resistance in a particular centre. Our exploratory approach was based on manual data processing. It would be interesting to consider a continuous systematic approach, allowing automatic generation of correlations.

Pharmacogenetic testing in pediatric neurology: a pragmatic study evaluating clinician and patient perceptions.

Aim: To evaluate clinicians' and patients' perceptions of pharmacogenetic testing in a clinical setting. Materials & methods: This is a pragmatic mixed-method prospective observational study. Hospital pharmacists and neurologists participated in focus groups regarding pharmacogenetic testing; patients who received pharmacogenetic testing and their community pharmacists completed surveys to assess their perception of these tests. Results: Most study participants had a positive view of pharmacogenetic testing. Three major themes were identified from the focus groups: receptiveness to pharmacogenetic testing, pharmacogenetic test characteristics and integrating pharmacogenetic tests into practice. Conclusion: The views reported are encouraging for the eventual implementation of pharmacogenetics in practice. Local integration of these tests is an essential step to improve patient care through personalized medicine.

Genetic tests can help predict patients' response to medication. This study aimed to evaluate clinicians' and patients' perceptions of these genetic tests. Pediatric patients, with epilepsy, were tested and completed a survey to assess their perception of these tests. A survey was also completed by their community pharmacists, and virtual discussion groups were held with hospital pharmacists and neurologists. Most participants had a positive view of these tests, with three major themes identified from the discussion groups: receptiveness to testing, test characteristics and integration of tests into practice. The views reported are encouraging for the eventual implementation of these tests in practice, an essential step to improve patient care through personalized medicine.

Surface contamination with nine antineoplastic drugs in 109 canadian centers; 10 years of a monitoring program.

INTRODUCTION: Healthcare workers exposure to antineoplastic drugs can lead to adverse health effects. Guidelines promote the safe handling of antineoplastic drugs, but no safe exposure limit was determined. Regular surface sampling contributes to ensuring workers safety. METHODS: A cross-sectional monitoring is conducted once a year with voluntary Canadian centers, since 2010. Twelve standardized sampling sites were sampled. Samples were analyzed by high performance mass coupled liquid chromatography. The limits of detection (in ng/cm2) were: 0.001 for cyclophosphamide and gemcitabine; 0.3 for docetaxel and ifosfamide; 0.04 for 5-fluorouracil and paclitaxel; 0.003 for irinotecan; 0.002 for methotrexate; 0.01 for vinorelbine. RESULTS: The surfaces from 109 centers were sampled between 01/01/2020-18/06/2020. Twenty-six centers delayed their participation because of the COVID-19 pandemic. 1217 samples were analyzed. Surfaces were frequently contaminated with cyclophosphamide (34% positive, 75th percentile 0.00165 ng/cm2) and gemcitabine (16% and <0.001 ng/cm2). The armrest of patient treatment chairs (84% to at least one drug), the front grille inside the biological safety cabinet (BSC) (73%) and the floor in front of the BSC (55%) were frequently contaminated. Centers that prepared ≥5000 antineoplastic drugs annually had higher concentration of cyclophosphamide on their surfaces (p < 0.0001). Contamination measured on the surfaces was reduced from 2010 to 2020. CONCLUSIONS: This large-scale study showed reproducible long term follow up of the contamination of standardized sites of Canadian centers and a reduction in surface contamination from 2010 to 2020. Periodic surface sampling help centers meet their continuous improvements goals to reduce exposure as much as possible. The COVID-19 pandemic had a limited impact on the program.

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.

Pharmacists' perceptions of a machine learning model for the identification of atypical medication orders.

OBJECTIVES: The study sought to assess the clinical performance of a machine learning model aiming to identify unusual medication orders. MATERIALS AND METHODS: This prospective study was conducted at CHU Sainte-Justine, Canada, from April to August 2020. An unsupervised machine learning model based on GANomaly and 2 baselines were trained to learn medication order patterns from 10 years of data. Clinical pharmacists dichotomously (typical or atypical) labeled orders and pharmacological profiles (patients' medication lists). Confusion matrices, areas under the precision-recall curve (AUPRs), and F1 scores were calculated. RESULTS: A total of 12 471 medication orders and 1356 profiles were labeled by 25 pharmacists. Medication order predictions showed a precision of 35%, recall (sensitivity) of 26%, and specificity of 97% as compared with pharmacist labels, with an AUPR of 0.25 and an F1 score of 0.30. Profile predictions showed a precision of 49%, recall of 75%, and specificity of 82%, with an AUPR of 0.60, and an F1 score of 0.59. The model performed better than the baselines. According to the pharmacists, the model was a useful screening tool, and 9 of 15 participants preferred predictions by medication, rather than by profile. DISCUSSION: Predictions for profiles had higher F1 scores and recall compared with medication order predictions. Although the performance was much better for profile predictions, pharmacists generally preferred medication order predictions. CONCLUSIONS: Based on the AUPR, this model showed better performance for the identification of atypical pharmacological profiles than for medication orders. Pharmacists considered the model a useful screening tool. Improving these predictions should be prioritized in future research to maximize clinical impact.

Soins plus ­ mise en place d'une intervention à trois volets visant à accroître la visibilité et la disponibilité du pharmacien dans un hôpital pédiatrique : une étude randomisée contrôlée.

BACKGROUND: The pharmacist's role within the multidisciplinary team is often poorly understood. Various interventions can be put into place to promote the role of the pharmacist in the hospital setting with families, patients, and other health care professionals. Few studies have described the feasibility and assessed the impact of such interventions, particularly in pediatrics. OBJECTIVES: To describe the implementation of a 3-part intervention aimed at increasing the visibility of pharmacists and their role on the treatment team, with the goal of optimizing the pharmaceutical care of hospitalized patients in the general pediatric units of CHU Sainte-Justine, in Montréal, Quebec, and to compare the perceptions and satisfaction of patients' parents and of health care professionals with exposure to either usual pharmaceutical care or to pharmaceutical care incorporating the intervention. METHODS: This single-blind, randomized, controlled experimental study involved patients admitted to general pediatric units between March 5 and August 8, 2019. In addition to usual care, the intervention included delivery of an information brochure about pharmaceutical services and care, access to a telephone line (which allowed families and patients to contact a pharmacy resident during their stay in hospital and up to 1 month after discharge), and completion of a standardized discharge form by the pharmacist responsible for the patient. The participants and health professionals concerned were surveyed to determine their perceptions and level of satisfaction. RESULTS: A total of 641 participants were included in the study, 321 in the intervention group and 320 in the control group. The brochure was given to all parents in the intervention group. Twelve phone calls were made through the dedicated telephone line. The standardized discharge form was completed for 46.7% (150/321) of the participants in the intervention group. Most of the parents and patients who responded to the survey, in either group (81.2%, 298/367), reported satisfaction with the pharmaceutical services and care received. Of participants in the intervention group, 83.9% were satisfied with the pharmaceutical care and services received, compared with 78.5% of those in the control group (p = 0.18). In addition, 60.3% (111/184) of participants in the intervention group said that the information about medications that was provided during the hospital stay gave them new knowledge, compared with 48.1% (87/181) of those in the control group (p = 0.019). The results of the survey showed that care providers were in agreement with the intervention. CONCLUSIONS: The 3 components of the intervention were implemented in the pediatric units over a period of 5 months. The intervention was perceived as positive by the parents and care providers concerned, and the respondents were mostly satisfied with the services and pharmaceutical care offered.

Utilisation de l'intelligence artificielle en pharmacie : une revue narrative.

BACKGROUND: Artificial intelligence (AI) can be described as an advanced technology in which machines display a certain form of intelligence. OBJECTIVES: The primary objective was to perform a narrative review of studies evaluating the feasibility and impact of AI in pharmacy. The secondary objective was to create a mind map of AI in health care. DATA SOURCES: Four databases were consulted: PubMed, Medline, Embase, and CINAHL. STUDY SELECTION AND DATA EXTRACTION: Four search strategies were developed. Initial selection of articles was based on their titles and abstracts; the full texts were then evaluated by a research assistant, with review by a pharmacist. Articles were included if they described or evaluated the feasibility or impact of AI in pharmacy. DATA SYNTHESIS: A total of 362 articles were identified by the literature review, of which 18 met the inclusion criteria. The studies were mainly conducted in the United States (72%, 13/18). The article topics were, in decreasing order, prediction of response to treatments and adverse effects (33%, 6/18), patient prioritization (28%, 5/18), treatment adherence (22%, 4/18), validation of prescriptions and electronic prescription (17%, 3/18), and other themes (e.g., diagnosis, costs, insurance, and verification of syringe volume). CONCLUSIONS: This narrative review highlighted 18 studies evaluating the feasibility and impact of AI in pharmacy. The studies used various methodologies in different settings, both retail pharmacies and hospital pharmacies. It is still too soon to predict the implications of AI for pharmacy, but these studies emphasize the importance of attention in this area.
