In hospitals oil based ink is occasionally used to write the patient's name, his room number, and names of the drugs that are used in a mixture on the plastic containers used for infusion. This is done to prevent medication errors. In the current study, the effect of an oil-based ink on the infusion fluid was investigated.Using an oil-based ink containing xylene, letters and other characters were written on an infusion fluid container that was made of Polypropylene·Polyethylene·Ethylene vinyl acetate. It was confirmed that some xylene had been transported to the interior of the container (air phase). Furthermore, the xylene concentration in the air phase rose with repetitive writing and erasing, using the same oil-based ink. But no xylene was dissolved in the solution that was in the container (liquid phase).This observation convinced us that it is highly unlikely that the xylene in the ink can be infused directly into a patient's body. However, to assure the quality of the medication that is in liquid form, it is not desirable for a substance that does not normally exist as a component of the medication to move through its container. In the present experiment, physiological saline was used as a solution (liquid phase). Our findings showed that xylene had a high possibility of dissolving in solutions known for high xylene solubility (e. g., solutions with a large amount of amino acids or surfactants). Therefore, it is necessary to design a method to prevent ink from entering a container when an oil-based ink is applied to the outside of it.

In hospitals oil-based ink is occasionally used to write the patient's name, his room number, and names of the drugs that are used in a mixture on the plastic containers used for infusion. This is done to prevent medication errors. In the current study, the effect of an oil-based ink on the infusion fluid was investigated. Using an oil-bused ink containing xylene, letters and other characters were written on an infusion fluid container that was made of Polypropylene・Polyethylene・Ethylene vinyl acetate. It was confirmed that some xylene had been transported to the interior of the container (air phase). Furthermore, the xylene concentration in the air phase rose with repetitive writing and erasing, using the same oil-based ink. But no xylene was dissolved in the solution that was in the container (Iiquid phase). This observation convinced us that it is highly unlikely that the xylene in the ink can be infused directly into a patient's body. However, to assure the quality of the medication that is in liquid form, it is not desirable for a substance that does not normally exist as a component of the medication to move through its container. In the present experiment, physiological saline was used as a solution (liquid phase). Our findings showed that xylene had a high possibility of dissolving in solutions known for high xylene solubility (e.g., solutions with a large amount of amino acids or surfactants). Therefore, it is necessary to design a method to prevent ink from centering a container when an oil-based ink is applied to the outside of it.

The most important aspect of an indwelling inter vascular catheters is to maintain the patency of the catheter. We recently developed a Heparin Lock Flush Solution Kit for use with center vein catheters (only in use at our Hospital). The kit consists of a syringe filled with 9 mL of normal saline (NS) and 1 mL of heparin (1000 IU/mL). We performed the following tests to evaluate the stability, sterility, seal, and dust identification in the preparation. The stability and sterility data indicated that heparin maintained its potency and had no bacterial contamination for 3 months. Testing the seal of the syringe indicated that the seal remained patent at a temperature range of 5°C to 60°C. We also found that even if we sterilized a syringe made of polypropylene using ethylene oxide gas (EOG), no toxins (i.e., ethylene oxide, ethylene chlorohydrin, ethylene glycol) were produced. Next, we examined the preparation time and cost to evaluate the practical benefit of developing the kit. According to our results, the estimated preparation time and cost were 43% and 29% less than for previous methods, respectively. Finally, we put a label on the medicine kit to prevent any misuse by the medical staff.

The questionnaire was distributed to caregivers regarding their management for home medication therapy. The purpose of this questionnaire was to clarify the role of community pharmacists in city “Z”, Hiroshima in supporting this activity. The results were compared among seven administrative zones. The percentage of caregivers who had routinely administered medications to dependent patients was 81%. Of these, the percentage of caregivers who had encountered difficulty in medication administration to dependent patients was 66%. Only 13% of these caregivers had sought assistance from pharmacists in dealing with issues they faced in the administration of medications. The percentage of caregivers who had easy access to pharmacists was 44%. The percentage of caregivers who received pharmacist-initiated information about patients was 23%. Among the 7 administrative zones in city “Z”, the 2 zones (H-zones) with the highest percentage of elderly citizens, 38.7%, were compared with the other 2 zones (L-zones) with the lowest percentage of elderly citizens, 25.7%, regarding medication management by caregivers. It was observed that the frequency of missing side effects or crushing medicines by caregivers was higher in H-zones as compared to L-zones. The results of this research suggest that close cooperation between pharmacists and caregivers improves the quality of medication therapy management. In an aging society, pharmacist intervention could be very beneficial to providing support and information that would improve the quality of patients’ medication therapy.
