　View Summary

Following the publication of a guideline on the safe handling of hazardous drugs (HDs) in Japan, the issue of cost-effectiveness has been become a problem. We introduced the PhaSeal™ system in June 2015, a closed system drug transfer devices (CSTD) used for all outpatients, from preparation to administration. We retrospectively compared clinical outcomes before and after the introduction of CSTD of HDs included chemotherapy. Furthermore, we evaluated the medical fee income and the cost of providing CSTD between July and December 2015. The mean number of outpatient chemotherapy treatments per day before and after CSTD introduction was 15 ± 6 and 14 ± 5, respectively (P = 0.947). The mean preparation time by pharmacists before and after introduction was 21 ± 9 and 24 ± 9 minutes, respectively (P = 0.002). The mean time of nursing preparation before and after introduction was 29 ± 16 and 25 ± 14 minutes, respectively (P = 0.068). The mean time of patients waiting for chemotherapy before and after introduction was 36 ± 17 and 37 ± 17 minutes, respectively (P = 0.735). Based on the mean differences between the medical fee income and the cost of CSTD per month, we estimated that the annual cost associated with the introduction of CSTD for all outpatient to administer HDs was approximately JPY 21,000,000. After April 2016, we estimated that the amount of increase of the medical fee income of CSTD was approximately JPY 2,000,000 per year. These results suggest that the medical fee income should be increased so CSTD can be implemented for all outpatients.

　View Summary

We retrospectively evaluated the clinical outcomes of pharmaceutical interventions relating to outpatient chemotherapy and estimated their associated economic impact between August 2014 and August 2015. We developed a novel pharmaceutical system, involving JPY1,164,000 allocated to a total of 582 patients. There were 117 proposals for pharmaceutical interventions, 106 (90.6%) of which were accepted by physicians. The number of proposals for supportive therapy was 56, 29 (51.8%) of which significantly decreased the grade of chemotherapy-induced adverse events compared to before pharmaceutical interventions (P < 0.001). The number of reductions in grade 1, 2, and 3 events was 14, 11 and 4, respectively. In this study, the potential economic costs associated with reduction of grade 1, 2 and 3 chemotherapy-induced adverse events were calculated as JPY112,000, JPY112,000, and JPY2,140,000, respectively, based on the costs paid by the Adverse Drug Reaction Relief System of the Pharmaceuticals and Medical Devices Agency. According to this cost calculation, we estimated that the total cost saving associated with the clinical outcomes of pharmaceutical interventions was JPY11,360,000. This is the first study to estimate the economic impact associated with the clinical outcomes of pharmaceutical interventions for outpatient chemotherapy. These results suggest that pharmaceutical interventions contribute to the quality and safety of outpatient chemotherapy by decreasing chemotherapy-induced adverse events.

　View Summary

The BD PhasealTM administration set, a new device for the BD PhasealTM closed system drug transfer device (CSTD), can prevent the occupational exposure of health caregivers to antineoplastic agents during all stages of the treatment process from preparation to administration. Further, a revised nursing approach for administration may prevent inadvertent antineoplastic agent spills. In this study, we compared the exposure levels of cyclophosphamide (CPA) and paclitaxel (PTX) between conventional methods and the new method described above; by sampling drug absorption sheets (a sampling sheet method) was used. In both methods, CPA was prepared using the BD PhasealTM CSTD and PTX was a plastic needle open system. For the new method, CPA was administered using the BD PhasealTM administration set and PTX was the revised nursing administration approach. Five pharmacists undertook the preparation process, and five nurses the administration process. Within the administration process using the conventional method, the following levels were detected: CPA 1.67 ng/cm2 and PTX 0.077 ng/cm2. No measurable levels were detected with the new method. For the preparation process, no CPA was detected, but PTX was detected. These results suggest that the use of the BD PhasealTM administration sets and the revised nursing administration approach is useful for preventing the occupational exposure of health caregivers to antineoplastic agents; this applies to both the preparation process and the administration processes.

　View Summary

A quantitative evaluation method has not yet been established for pharmacy students in relation to learning achievements and their hospital-based practical training. We therefore developed an outpatient chemotherapy educational program to address this issue. To assess the learning achievements quantitatively, we carried out four examinations - twice at the halfway point (first) and at the program's term-end (second); a perfect score was 100. This study was conducted between May and November 2013 and 24 pharmacy students participated. The results showed that the first and second mean scores relating to their cytotoxic agent handling knowledge were 91.5 ± 5.2 and 99.1 ± 1.8, respectively. The first and second mean scores relating to preparation skills for vials (how to handle anticancer drugs) were 68.5 ± 13.1 and 78.9 ± 18.5, respectively. For their preparation skills (using closed systems to handle anticancer drugs) the mean scores were 85.2 ± 13.1 (first) and 97.0 ± 3.7 (second). The first and second mean scores about the processes involved in solving chemotherapy-related patient problems were 52.1 ± 23.7 and 77.8 ± 21.9, respectively. All of the scores were significantly increased at the end of the program compared with scores halfway through. These results suggest that our program may be useful for supporting pharmacy students to learn more effectively during their hospital-based practical training in Japan.

　View Summary

Purpose: The aim of this study was to clarify the risk factors for discontinuing tegafur/gimeracil/oteracil potassium (S-1) adjuvant chemotherapy following gastrectomy in patients with gastric cancer.
Methods: We retrospectively investigated patients with curatively-resected gastric cancer who received S-1 adjuvant chemotherapy. S-1 was administered orally at 80-120 mg/day, depending on body surface area, on days 1-28 every 6 weeks for 1 year. The dose and treatment schedule were modified at the clinicians' discretion, according to toxicity.
Results: Seventy-one patients were included in the study, 26 of whom discontinued S-1 therapy. The relapse-free survival rates in the S-1-completed and S-1-discontinuation groups at 5 years post-surgery were 88.1% and 55.8%, respectively. The overall survival rates in the S-1-completed and S-1-discontinuation groups at 5 years post-surgery were 89.4% and 59.8%, respectively. The hazard ratios for relapse and death were significantly lower in the S-1-completed group compared with those in the S-1-discontinuation group (0.18; p<0.001 and 0.19; p=0.002, respectively). Multivariate logistic regression analysis revealed that S-1 discontinuation was significantly associated with an initial overdose of S-1, having stage I cancer, creatinine clearance <66 mL/min, and a side effect of nausea.
Conclusions: These results suggest that assessing renal function to avoid initial overdose of S-1, together with the early management of side effects, may support the continuation of S-1 adjuvant chemotherapy in patients with gastric cancer.

　View Summary

Community pharmacies play a significant role in home healthcare. However, patient information from hospitals is not shared with community pharmacies. We attempted the bidirectional sharing of patient information regarding chemotherapy between hospitals and community pharmacies. We developed a “medicine message board,” which was a modified prescription format. Hospital pharmacists recorded information regarding patients taking tegafur/gimeracil/oteracil (S-1) on the message board. In turn, community pharmacists monitored side effects in the S-1 patients and returned the information by fax to our hospital also using the message board. A medical clerk entered the side effects into the electronic medical record, providing feedback to doctors. We distributed questionnaires to community pharmacies around our hospital between December 2013 and January 2014 and assessed their understanding using a five-point Likert scale (where 1 = insufficiency and 5 = sufficiency). The results showed that the mean scores on understanding about the presence or absence of cancer notification before and after the initiation of the message board were 2.10 ± 1.02 and 4.20 ± 1.06, respectively. The mean understanding about the name of a cancer patient's disease before and after the message board was 2.25 ± 0.91 and 4.45 ± 0.83, respectively. All these differences were significant. Understanding about the purpose of treatment, dose adjustments of S-1 due to body surface area and renal function, administration schedule, presence or absence of combination chemotherapy, pharmaceutical instructions, treatment adherence, and side effects monitoring were also significantly improved in community pharmacies after the initiation of the message board. These results suggest that there is scope to improve the support provided to oral chemotherapy patients by hospitals and community pharmacists.

　View Summary

There is a lack of opportunities in Japan to engage in communication skills education about effective interactions between pharmacists and medical staff. This is despite the fact that current pharmacy education programs should be producing clinical experts in this area. Because of this, we delivered an educational program relating to building communication skills when working in a multidisciplinary team; 29 pharmacy students took part between May and November 2011. The program was based on two components: a lecture about communication skills by a facilitator (including “active listening”, “assertiveness” and “conflict management”), and a small group discussion (SGD) relating to decisions about opioid increases/rotation using a cancer pain case as an alternative opioid treatment. After the students finished the SGD, we distributed questionnaires to them and assessed outcomes using a five-grade Likert scale. As a result of the questionnaires, their mean understanding about opioid increasing and opioid rotation were 4.59 ± 0.68 and 4.48 ± 0.69, respectively. The mean implementation score of communication skills relating to “assertiveness” was 3.62 ± 0.94, which was significantly worse when compared with that of “active listening” (4.31 ± 0.60, P = 0.003). In addition, the mean satisfaction levels of the SGD group work and the overall educational program were 4.31 ± 0.81 and 4.38 ± 0.62, respectively. Care is required when interpreting the results given the study was limited to a single institution. However, these results suggest that this type of program may be useful for supporting pharmacy students to learn about communication skills. Improved skills should result in more effective communication, when pharmacists interact with medical staff.

　View Summary

A retrospective study was carried out to compare the preventive effects of single and repeat treatment with dexamethasone (DEX) on delayed nausea and emesis in patients who had received carboplatin (CBDCA)-based combination chemotherapy. Sixty-four patients were evaluated. Efficacy was assessed using the nausea and emesis score, food intake score and the requirement for antiemetic medication. These forward scores were categorized as three-grade during the first 5 days after chemotherapy. Acute nausea and emesis were well controlled in both groups on day 1. Mean values of the nausea and emesis score on day 3 evening and the food intake score on day 4 morning in the repeat-treatment group was 1.31 ± 0.93 and 3.46 ± 1.03, respectively, which were significantly better when compared with the singletreatment group (2.00 ± 1.52; P = 0.028 and 2.79 ± 1.12; P = 0.018, respectively). Multivariate logistic regression analysis revealed that less frequent dispensing of antiemetic medication was significantly associated with the repeat-treatment group (adjusted odds ratio, 0.153; 95% confidence interval, 0.026-0.734; P = 0.018). These results suggest that repeat-dose DEX may be more effective than single-dose DEX for the prevention of delayed nausea and emesis after CBDCA-based combination chemotherapy.

　View Summary

There have so far been few reports of the pharmacokinetics of oxaliplatin in patients with renal impairment. This report describes the nephrotoxicity induced by repeated cycles of oxaliplatin in a Japanese colorectal cancer patient with moderate renal impairment(creatinine clearance(Ccr): 20-30mL/min). The patient was a 77-year-old male who had chronic renal impairment and received the modified FOLFOX6 repeated every 2 weeks. In cycle 8, the blood concentration of oxaliplatin(66 mg/m2)was measured as the platinum level to confirm the patient's safety. The serum ultrafiltrate concentrations of platinum were 800, 1, 000, 300, <200, and <200 ng/mLat 1, 2, 3 hr, 1 week, and 2 weeks after the start of infusion, respectively, which were closely comparable with the population pharmacokinetic data in Japanese patients with normal renal function. On the other hand, the serum creatinine value was gradually increased after cycle 6, resulting in a decrease of Ccr. The mean Ccr during day 1-59 and day 240-299were significantly different at 26. 5+/-2. 8(mean+/-SD)and 9. 6+/-1. 9mL/min, respectively. Consequently, the chemotherapy showed a complete response after 10 cycles, but the patient got dialysis on day 311. In conclusion, the repeated cycles of oxaliplatin cumulatively damaged the renal function in a Japanese patient with a moderate renal impairment.
