Prevention of Acne-Like Eruption Caused by Panitumumab Treatment through Oral Administration of Non-steroidal Anti-inflammatory Drugs.

Acne-like eruption caused by anti-epidermal growth factor receptor (EGFR) antibodies such as panitumumab reduces treatment adherence and patient QOL; an alternative therapy is desired. Meanwhile, the usefulness of oral Non-steroidal Anti-inflammatory Drugs (NSAIDs) for acne-like eruptions caused by low-molecular-weight EGFR inhibitors such as erlotinib has been reported in the treatment of lung cancer. This study aimed to investigate whether the combined use of oral NSAIDs and panitumumab for colorectal cancer patients helps prevent acne-like eruption. We retrospectively investigated 167 colorectal cancer patients who had been treated with panitumumab for three cycles or more. The observation period was set from the start of panitumumab treatment to the end of three cycles. Within this period, the incidence and severity of acne-like eruptions were compared. A total of 59 and 108 patients were in the NSAIDs use and non-use groups, respectively, showing differences in the incidence of acne-like eruption rates (78.0 vs. 90.7%, respectively; p = 0.033). In the use group, eruption severity grades 0, 1, 2, and 3 were observed in 13, 33, 13, and 0 patients, respectively; the corresponding values in the non-use group were 10, 60, 36, and 2, respectively (p = 0.007). Oral NSAIDs may help prevent acne-like eruptions caused by panitumumab.

Pharmacists' Adherence Support System FollowNavi for Patients with Type 2 Diabetes.

In Japan, the Pharmaceutical and Medical Device Act was amended in December 2019 and now requires pharmacists to follow-up patients continuously during treatment to ensure proper use of medicines. According to some reports on patients with type 2 diabetes mellitus (T2DM), follow-up by doctors is effective for improving treatment. Enhanced face-to-face medication counseling by pharmacists leads to good glycemic control in patients with diabetes. However, the effects of information and communication technology (ICT)-based follow-up during the medication period are not well-understood. We determined the efficacy of pharmacists' follow-up using FollowNavi, a patient compliance instruction support system, and using our developed LINE tool for patients with T2DM. Through a before-after study, changes in glycemic control and medication adherence after 6 months of follow-up were investigated, and multiple regression analysis was performed to investigate the factors associated with changes in hemoglobin A1c (HbA1c) levels. Questionnaire surveys related to usability were completed by patients and pharmacists. In the 35 patients with T2DM, HbA1c levels decreased significantly after 6 months, although fasting blood glucose levels and medication adherence showed no significant differences. Changes in HbA1c levels were significantly associated with age (p = 0.044), baseline HbA1c levels (p < 0.001), and diabetes duration (p = 0.004). In the questionnaire, 81.8% of patients responded that they would prefer to continue using FollowNavi. These results suggest that follow-up using FollowNavi is useful for glycemic control in patients with T2DM.

Exploration of Trends in Antimicrobial Use and Their Determinants Based on Dispensing Information Collected from Pharmacies throughout Japan: A First Report.

The purpose of this study was to evaluate the defined daily doses (DDD)/1000 prescriptions/month (DPM) as a new indicator that can be used in pharmacies, and to describe antimicrobial use patterns in pharmacies nationwide in Japan. Dispensing volumes, number of prescriptions received, and facility information were obtained from 2638 pharmacies that participated in a survey. DPM was calculated based on the dispensing volume and number of prescriptions, which are routinely collected data that are simple to use. Use of third-generation cephalosporins, quinolones, and macrolides in pharmacies that received prescriptions primarily from hospitals or clinics decreased from January 2019 to January 2021. In particular, the antimicrobial use was higher in otorhinolaryngology departments than in other departments, despite a decrease in the antimicrobial use. In the linear multiple regression analysis, otorhinolaryngology department was independently associated with the third-generation cephalosporin, quinolone, and macrolide prescription in all periods. This study reveals for the first-time trends in antimicrobial use through a new indicator using the volume of drugs dispensed in pharmacies throughout Japan. Antimicrobial use differed by the medical department, suggesting the need to target interventions according to the department type.

Examining the association between the "My Pharmacist" model and the service quality of community pharmacies.

BACKGROUND: In Japan, patients can freely choose medical facilities. Many visit different medical facilities for different diseases, and for convenience, often utilize the pharmacies neighboring these facilities. Accordingly, a "My Pharmacy" model was recommended, in which patients select a single pharmacy using their own judgement to receive proper medication services. A "My Pharmacist" model, in which the pharmacist is constantly involved in the treatment of a patient, was also proposed. However, patients' evaluations of pharmacist/pharmacy services under these models have not been investigated. OBJECTIVE: To examine how a patient's constant involvement with the same pharmacist and pharmacy is associated with their evaluation of the quality of pharmacy services. METHODS: A cross-sectional survey using a self-administered questionnaire was conducted among patients who used pharmacies periodically. Patients evaluated the pharmacist/pharmacy services and were classified into 4 groups ("My Pharmacy/My Pharmacist," "My Pharmacy/Multiple Pharmacists," "Multiple Pharmacies/My Pharmacist," and "Multiple Pharmacies/Multiple Pharmacists") according to the form of their usage of pharmacies and pharmacists. An intergroup comparison was then performed and correlations within each group analyzed. RESULTS: Data from 3,492 individuals using 147 pharmacies were analyzed. "My Pharmacy" users had significantly higher scores than did "Multiple Pharmacies" users on patient experience of proper medication services (e.g., identifying duplicate medication) (p < 0.001). "My Pharmacy/My Pharmacist" users scored higher than the other three groups on four evaluation factors, including "pharmacy/pharmacist's interpersonal services" ("sharing and utilizing patient information," "enhanced health support function," and "consideration towards patients"), "patient satisfaction with the pharmacy," "placing more emphasis on quality of interaction with pharmacist than on waiting time," and "attitude when visiting healthcare facilities" (all p < 0.001). CONCLUSION: The findings indicate that highly tailored, in-person services provided by "My Pharmacists" are associated with not only with the degree of patients' overall satisfaction, but also their evaluation of "the quality of pharmacist services."

Reduction of Medical Cost through Pharmaceutical Inquiries by Community Pharmacists and Relation with Iyaku Bungyo Rates: A Nationwide Survey on Prescription Inquiries.

This nationwide survey aimed to evaluate reduction of drug and medical costs due to prevention of serious adverse drug reactions through pharmaceutical inquires by community pharmacist, and investigate relation with iyaku bungyo (separation of dispensing from medical practice) rates. Using the national list of pharmacies, 10% of pharmacies were randomly selected by prefecture and asked to participate in an Internet-based survey. The survey period was 7 days, from July 21 to July 27, 2015. Of the 5575 pharmacies queried, 818 responded to the survey (response rate: 14.7%). The proportion of inquiries to total prescriptions was 2.6%. Among these, the proportion of prescriptions changed in response to inquiry was 74.9%. An estimated 103 million yen was saved by reducing drug costs, and 133 million yen was saved by reducing medical costs due to prevention of serious adverse drug reactions. Comparison of prescription change rates between pharmacies with high and low iyaku bungyo rates indicated that the proportion of prescriptions changed was significantly higher in pharmacies with high iyaku bungyo rates than in those with low iyaku bungyo rates (78.2% vs. 69.9%, p<0.01). The findings suggest that inquiries about prescriptions are useful in ensuring the safety of pharmacotherapy and reducing the cost of healthcare. They also suggest that iyaku bungyo promotes prescription changes through inquiries, leading to proper use of pharmaceutical products.

[A research of letter color visibility in package insert information using simulator].

Package insert of pharmaceutical drug is one of the most prioritized information for pharmacists to secure safety of patients. However, the color of character, size, font and so on are various company by company product to product from a viewpoint of visibility. It may be cause a serious accident in case visibility is unclear, although it is the most important information. Moreover, package insert with high visibility is required for color vision defectives from a viewpoint of a universal design. Then, the authors selected the package insert which has the boxed warning in the ethical pharmaceutical currently stored mostly in the present health insurance pharmacy and quantified the red color using the color meter. We advocate the state of a suitable package insert from a viewpoint of a universal design, whether the red color is high visible or not for color vision defectives using simulator.

[Medical economics research on awareness of community pharmacists about raising pharmaceutical questions regarding prescriptions issued by physicians].

This study examined the impact of pharmaceutical inquiries regarding prescriptions on drug costs by surveying the actual condition of inquiries at 13 pharmacies. The study also investigated the significance of inquiries from a medical economics perspective by calculating the medical cost savings realized by preventing adverse drug reactions (ADRs). As a result, the total change in drug costs for the 13 pharmacies after pharmaceutical inquiries represented an increase of ¥9,018/month. However, upon recalculating the cost of drugs by assuming that those with an "Incomplete entry in the prescription (compared with previous prescription, etc.)" should in fact have been prescribed, and excluding them, the total drug costs for the 13 pharmacies is decreased to ¥154,743/month, translating to a cost-savings of ¥7.2/prescription. The study then undertook a comprehensive assessment based on the Diagnosis Procedure Combination (DPC) system to determine the total medical cost-savings for 5 patients in whom ADRs could have occurred if the prescriptions had not been modified as a result of pharmaceutical inquiries. The obtained figure of ¥1,188,830 suggests that pharmaceutical inquiries contribute to reduced medical costs. The findings of this study indicate that pharmaceutical inquiries regarding prescriptions by staff pharmacists not only ensure the proper delivery of drug therapy to patients, but are also effective from a medical economics perspective.

[Survey on the awareness of community pharmacists about raising pharmaceutical questions regarding prescriptions issued by physicians].

Community pharmacists can provide effective pharmaceutical care by questioning the physicians about their prescriptions. The regulatory authority (Ministry of Health, Labour and Welfare or the like) has been issuing instructions/advice to health insurance-covered pharmacies about the nature of questions to be asked to physicians under the national health insurance system. However, this practice has been facing similar kind of problems almost every year. To identify the reasons for repetition of the problems and facilitate proper application of drug therapy at hospitals, we recently examined the nature of questions asked to physicians by conducting a survey of 165 health insurance-covered pharmacies belonging to 8 district branches of the Japan Pharmaceutical Association. When the pharmacists were asked to express their view whether each of the 18 sample questions included in the past surveys was actually necessary, the most frequent answer from the respondents (n=1980) was "neutral" (42.9%), followed by "unnecessary" (29.0%) and "necessary" (26.6%). Further, 55.5% respondents answered that it is necessary to refer to publications of the concerned fields (guidelines, etc.) when questioning the prescriptions. However, the responses about the possible reasons for judging the necessity of the questions suggested that sometimes the pharmacists failed to understand the details of such publications. The results from this study suggest that a high percentage of community pharmacists believed that there was little need to ask questions about prescriptions if the suggestions made by the regulatory authority about the relevant questions were taken into account. Further, our study findings suggested that pharmacists working at clinics cannot present a clear-cut rationale for their judgment about the necessity of asking questions about prescriptions under the current circumstances where sufficient information collection and the evaluation of need for asking questions about prescriptions are not possible.
