Evaluating and Managing the Microbial Contamination of Eye Drops: A Two-Phase Hospital-Based Study.

The microbial contamination of eye drop tips and caps varies between 7.7% and 100%. In seeking patient protection and continuous improvement, the Pharmacy Department in the Sterile Ophthalmological and Oncological Preparations Unit at Cochin Hospital AP-HP, Paris, France, conducted a two-phase study to compare the antimicrobial efficiency and practical use of standard packaging and a marketed eye drop container incorporating a self-decontaminating antimicrobial green technology by Pylote SAS at the tip and cap sites. The first phase was conducted in situ to identify the microbial contaminants of eye drops used in the hospital and community settings. A total of 110 eye drops were included for testing. Staphylococcus species were the most prevalent bacteria. Candida parapsilosis was detected in only one residual content sample and, at the same time, on the cap and tip. The second phase was performed in vitro, according to JIS Z2801. Reductions above one log in Staphylococcus aureus and Pseudomonas aeruginosa counts were noted in Pylote SAS eye drop packaging after 24 h of contact. The practical tests showed satisfactory results. Pylote SAS antimicrobial mineral oxide technology exhibited promising effects that combined effectiveness, safety, and sustainability to protect the patient by preventing infections due to the contamination of eye drop containers.

Robotic chemotherapy compounding: A multicenter productivity approach.

INTRODUCTION: The aim of this study is to compare productivity of the KIRO Oncology compounding robot in three hospital pharmacy departments and identify the key factors to predict and optimize automatic compounding time. METHODS: The study was conducted in three hospitals. Each hospital compounding workload and workflow were analyzed. Data from the robotic compounding cycles from August 2017 to July 2018 were retrospectively obtained. Nine cycle specific parameters and five productivity indicators were analysed in each site. One-to-one differences between hospitals were evaluated. Next, a correlation analysis between cycle specific factors and productivity indicators was conducted; the factors presenting a highest correlation to automatic compounding time were used to develop a multiple regression model (afterwards validated) to predict the automatic compounding time. RESULTS: A total of 2795 cycles (16367 preparations) were analysed. Automatic compounding time showed a relevant positive correlation (ǀrs|>0.40) with the number of preparations, number of vials and total volume per cycle. Therefore, these cycle specific parameters were chosen as independent variables for the mathematical model. Considering cycles lasting 40 minutes or less, predictability of the model was high for all three hospitals (R2:0.81; 0.79; 0.72). CONCLUSION: Workflow differences have a remarkable incidence in the global productivity of the automated process. Total volume dosed for all preparations in a cycle is one of the variables with greater influence in automatic compounding time. Algorithms to predict automatic compounding time can be useful to help users in order to plan the cycles launched in KIRO Oncology.

Qualification of a chemotherapy-compounding robot.

KIRO® Oncology (Kiro Grifols, Spain) is a robotic system for automated compounding of sterile injectable drugs including intravenous cytotoxic treatments. The present article describes the qualification procedure applied prior to production phases. Peristaltic pumps which ensure the reconstitution of drugs were tested with water and NaCl 0.9%. The performance of the robot (accuracy and precision) to prepare bags, syringes and elastomeric pumps was evaluated with three placebo solutions (aqueous, foaming and viscous) using gravimetric controls. Microbiological controls were also performed. The pumps met the requirements set for volumes ranging from 5 to 100 mL. A total of 274 preparations was compounded. For the bags, the filling accuracy was within the limit of ±10% from 1 to 48 mL with aqueous solution, from 0.6 to 48 mL with foaming solution and from 5 to 48 mL with viscous solution. For all syringes and elastomeric pumps, it was within the limit of ±10%. The precision was validated for all preparations, except for bags and syringes prepared with 0.6 and 0.25 mL, respectively. The samples of surfaces and air complied with ISO 5 class environment. Among the 24 gloves tests performed, two presented microbiological growth. All Media fill tests were validated. The qualification procedure led us to exclude injections of any active principle volume strictly lower than 1 mL. The microbiological contamination of operators' gloves remains a critical point. Our operators will be made aware of the issue during the training period.

How well Informed are Cancer Patients Prior to a Life Cycle of Injectable Chemotherapy Drug Treatment?

Cancer patient dissatisfaction, due to a long waiting time for chemotherapy treatment, is a common complaint. To improve patient satisfaction, our pharmaceutical team was prompted to design a series of information tools for injectable chemotherapy drug treatment (ICDT) patients. This study was based on French Health Authorities recommendations. All three stages were monitored: the preparation stage using a 204 patient survey, the design stage, and the assessment stage with a 12 point questionnaire patient evaluation. An information brochure and a 10-min film were designed which chronologically described key stages in the life cycle of ICDT. Both tools were assessed by 29 and 84 patients respectively. The questionnaire confirmed that this approach met the needs of more than 90 % of patients. The brochure and the film also accurately met the objectives and improved the understanding of the chemotherapy long waiting time which resulted in higher patient satisfaction. The designed tools will continue to evolve with changes in oncology practices based on various indicators defined in the study. Our study proposes an original method to assist health professionals to better inform cancer patients regarding the preparation of ICDT. It is also a part of a continuous quality program to assure quality outpatient healthcare.
