Evaluation of hospital pharmacists' activities using additional reimbursement for infection prevention as an indicator in small and medium-sized hospitals.

BACKGROUND: Hospitals in Japan established the healthcare delivery system from FY 2018 to 2021 by acquiring an additional reimbursement for infection prevention (ARIP) of category 1 or 2. However, research on outcomes of ARIP applications related to the practice of hospital pharmacists is scarce. METHODS: This study assessed the activities performed by hospital pharmacists in hospitals with 100 to 299 beds, using ARIP acquirement as an indicator, using data from an annual questionnaire survey conducted in 2020 by the Japanese Society of Hospital Pharmacists on the status of hospital pharmacy departments. Out of the survey items, this study used those related to hospital functions, number of beds, number of pharmacists, whether the hospital is included in the diagnosis procedure combination (DPC) system, average length of stay, and nature of work being performed in the analysis. The relationship between the number of beds per pharmacist and state of implementation of pharmacist services or the average length of hospital stay was considered uncorrelated when the absolute value of the correlation coefficient was within 0-0.2, whereas the relationship was considered to have a weak, moderate, or strong correlation when the absolute value ranged at 0.2-0.4, 0.4-0.7, or 0.7-1, respectively. RESULTS: Responses were received from 3612 (recovery rate: 43.6%) hospitals. Of these, 210 hospitals meeting the criteria for ARIP 1 with 100-299 beds, and 245 hospitals meeting the criteria for ARIP 2 with 100-299 beds, were included in our analysis. There was a significant difference in the number of pharmacists, with a larger number in ARIP 1 hospitals. For the pharmacist services, significant differences were observed, with a more frequency in ARIP 1 hospitals in pharmaceutical management and guidance to pre-hospitalization patients, sterile drug processing of injection drugs and therapeutic drug monitoring. In DPC hospitals with ARIP 1 (173 hospitals) and 2 (105 hospitals), the average number of beds per pharmacist was 21.7 and 24.7, respectively, while the average length of stay was 14.3 and 15.4 d, respectively. Additionally, a weak negative correlation was observed between the number of pharmacist services with "Fairly well" or "Often" and the number of beds per pharmacist for both ARIP 1 (R = -0.207) and ARIP 2 (R = -0.279) DPC hospitals. Furthermore, a weak correlation (R = 0.322) between the average number of beds per pharmacist and the average length of hospital stay was observed for ARIP 2 hospitals. CONCLUSIONS: Our results suggest that lower beds per pharmacist might lead to improved pharmacist services in 100-299 beds DPC hospitals with ARIP 1 or 2. The promotion of proactive efforts in hospital pharmacist services and fewer beds per pharmacist may relate to shorter hospital stays especially in small and medium-sized hospitals with ARIP 2 when ARIP acquisition was used as an indicator. These findings may help to accelerate the involvement of hospital pharmacists in infection control in the future.

Dexamethasone to prednisolone rotation relieved hiccups in colorectal cancer patient continuing teleworking during anticancer therapy.

We present a case of chemotherapy-induced hiccups that were alleviated by steroid rotation. Hiccups are often overlooked, but they have an impact on the patient's quality of life. In the COVID-19 era, web-based teleworking has become an important tool, hiccups during a teleconference should be noted as a concern for patients.

Retrospective analysis of atlantoaxial rotatory fixation describing age distribution and gender ratio in children and adolescents: A preliminary report.

INTRODUCTION: Atlantoaxial rotatory fixation (AARF) in children presents with an acute onset of neck pain. Almost all cases heal within a few days of onset and are treated conservatively. Because few cases of AARF have been reported, the age distribution or gender ratio of AARF in the child population have not been described enough. In Japan, the social insurance system covers all citizens. Thus, we used insurance claims data to investigate the features of AARF. The aim of this study is to examine the age distribution, compare gender ratio and determine the recurrence proportion of AARF. METHODS: We used the JMDC database to search for claims data submitted between January 2005 and June 2017 for cases of AARF in patients aged <20 years. RESULTS: We identified 1949 patients with AARF, of which 1102 (56.5%) were male. The mean age was 98.3 ± 42.2 months and 91.6 ± 38.4 months in males and females, respectively, and males with AARF were significantly older at onset than females with AARF (p < 0.001). In both sexes, the highest frequency of AARF occurred when the patient was 6 years old. There were 121 (6.2%) cases of recurrent AARF (male: 61, 5.5%; female: 60, 7.1%), but the age differences between the sexes in these cases were not statistically significant. CONCLUSIONS: This is the first report to describe the characteristics of the study population of AARF. Males were more likely to suffer from AARF than females. Furthermore, age (in months) at AARF onset was significantly higher in males than in females. Recurrence rate was not significant in both sexes.

Failure of liposomal amphotericin B therapy in patients with severe pancreatitis complicated by Candida lusitaniae infection.

Candida lusitaniae is an uncommon pathogen that accounts for approximately 1% of patients with candidiasis. In this report, we present the case of a 24-year-old woman with severe pancreatitis who was emergently admitted to Northern Yokohama Hospital. We started treating the pancreatitis and infections according to her culture results. However, her symptoms, accompanied by a necrotic pancreas, did not improve. Finally, C. lusitaniae was detected in the blood and catheter samples. We started antifungal treatment according to the culture results, but the patient died. Generally, the mortality rate for acute pancreatitis ranges from 3% for patients with interstitial edematous pancreatitis to 17% for those who develop pancreatic necrosis. Although we chose appropriate antibiotics and antifungal agents based on the culture results, the treatments failed. Early detection, sufficient doses of antimicrobials and frequent monitoring using sample culture are crucial because infection control may be inadequate, especially in tissues with low blood flow, such as necrotic tissues.

Actual status of patient information sharing among healthcare delivery facilities: a survey by the third subcommittee, committee on academic research, the Japanese society of hospital pharmacists.

BACKGROUND: Information sharing among medical professionals is important for providing quality medical care. The purpose of the present study was to elucidate the actual status of information sharing between hospitals and other healthcare delivery facilities by surveying information sharing among the pharmaceutical departments of Japanese hospitals in 2020 conducted by the Japanese Society of Hospital Pharmacists. METHODS: Responses were received from 3612 (43.6%) of the 8278 target medical institutions between May 2020 and August 2020. RESULTS: The proportions of hospitals that shared information with community pharmacies, other hospitals, and long-term nursing homes were 40.6%, 36.4%, and 27.3%, respectively. While tracing reports were the most common tool used by hospitals for information sharing with community pharmacies (54.3%), drug summaries were used for sharing information with other hospitals and long-term nursing homes (77.4% and 78.0%, respectively). The proportion of hospitals sharing information with community pharmacies and other hospitals showed a tendency to increase as the number of hospital beds increased. No relationship could be established between the number of hospital beds and the proportion of hospitals sharing information with long-term nursing homes. CONCLUSION: Information between hospitals and community pharmacies was shared primarily using tracing reports, whereas information between hospitals and other hospitals and long-term nursing homes was primarily shared via drug summaries.

Identification of the Components of Proton Pump Inhibitors and Potassium-Competitive Acid Blocker That Lead to Cardiovascular Events in Working-Age Individuals: A 12-Month Retrospective Cohort Study Using a Large Claims Database.

This study aimed to identify the components of proton pump inhibitors (PPIs) or potassium-competitive acid blocker (PCAB) that lead to cardiovascular events in individuals of working age. We analyzed large claims data of individuals who were administered PPIs or PCAB. We enrolled working-age individuals administered PPI or PCAB without cardiovascular history with a 12-month screening and 12-month observation period and determined the proportion of cardiovascular events and the predictive factors of cardiovascular events in this population. Among the eligible individuals, 0.5% (456/91098) had cardiovascular events during the 12-month observation period. Predictive factors for cardiovascular events were age for +1 year (p < 0.0001), male sex (p < 0.0001), hypertension (p = 0.0056), and diabetes mellitus (p < 0.0001). The cardiovascular disease risk was higher in working-age individuals administered lansoprazole than in those administered other drugs (vs. rabeprazole; p = 0.0002, vs. omeprazole; p = 0.0046, vs. vonoprazan; p < 0.0001, and vs. esomeprazole; p < 0.0001). We identified the risk for cardiovascular events in individuals being treated with lansoprazole. Lansoprazole is known for its higher CYP2C19 inhibition activity compared with other PPIs or PCAB. A possible mechanism by which lansoprazole may lead to cardiovascular events is inhibiting the generation of epoxyeicosatrienoic acids from arachidonic acids, an intrinsic cardioprotective activator via CYP2C19 inhibition. Thus, we recommend avoiding administering lansoprazole to working-age individuals require PPIs or PCAB.

Characteristics of hospitals that report adverse drug reactions: Results of a nationwide survey in Japan.

WHAT IS KNOWN AND OBJECTIVE: Adverse drug reactions (ADRs) are one of the primary reasons for hospitalization. The spontaneous reporting of ADRs by healthcare professionals is important for issuing post-marketing drug safety measures. The Japanese Society of Hospital Pharmacists (JSHP) conducts a nationwide survey annually. Using data from this large-scale survey, we identified the characteristics of hospitals that reported ADRs to regulatory authorities and pharmaceutical companies. METHODS: Data were obtained from annual surveys conducted by JSHP from 2015 to 2020. All variables were expressed as categorical variables and tabulated. The Chi-square test was used to compare the categorical variables. The Cochran-Armitage trend test was used to identify significant trends in the proportion of hospitals reporting ADRs. RESULTS AND DISCUSSION: From 2015 to 2020, 22,362 responses were recorded. There was a significant increase in the proportion of hospitals that reported ADRs with an increase in number of beds and pharmacists (p < 0.0001). The proportion of hospitals reporting ADRs to regulatory authorities was also significantly higher in those charging an additional fee for pharmacist-performed ward operations and in those with an ADR data management section than in hospitals without these attributes (p < 0.0001). WHAT IS NEW AND CONCLUSION: Hospitals that submitted ADR reports to the regulatory authorities and pharmaceutical companies charged an additional fee for pharmacist-performed ward operations, had a central ADR data management section, and had fewer beds per pharmacist. This trend was similar, regardless of the size of the hospital.

Irinotecan-induced severe hypotension in a patient with lung cancer.

Most hypotension during chemotherapy is caused by an allergic mechanism. Conversely, non-allergic hypotension due to chemotherapy is rare. In this case report, we present a patient who suffered severe hypotension followed by the administration of irinotecan-based chemotherapy and some supportive care such as steroids for preventing emesis. A 71-year-old man with hypertension was diagnosed with stage IV small cell lung cancer (sT1cN3M0). Severe hypotension occurred in the patient after every administration of chemotherapy. Finally, he was able to receive all four courses of chemotherapy as planned along with the medical staff's support care. This case provides that a regimen that contained irinotecan and steroid could cause hypotension and the mechanism is partially explained by inhibiting choline esterase and adrenal insufficiency. We should be careful about non-allergic hypotension when we administer irinotecan-based chemotherapy.

Prescription pattern analysis for antibiotics in working-age workers diagnosed with common cold.

Antimicrobial resistance is a major health concern. A primary cause is the inappropriate use of antimicrobials, particularly by patients with upper respiratory tract infection. However, baseline information for antibiotic use for common cold before being applied the National Action Plan on Antimicrobial Resistance in Japan is lacking. Here, we analyzed the inappropriate use of antibiotics in the working-age workers. We used large claims data from an annual health check-up for at least 5 consecutive years. Among 201,223 participants, we included 18,659 working-age workers who were diagnosed with common cold at a clinic/hospital. We calculated the proportion of patients with common cold who were prescribed antibiotics and analyzed predictive factors associated with antibiotics prescription. Antibiotics were prescribed to 49.2% (n = 9180) of patients diagnosed with common cold. In the logistic regression analysis, the group taking antibiotics was predominantly younger, male, without chronic diseases, and diagnosed at a small hospital/clinic (where the number of beds was 0-19). Cephems accounted for the highest proportion of prescribed antibiotics, with 40-45% of patients being prescribed antibiotics. Our data may be applied to prioritize resources such as medical staff-intervention or education of working-age people without chronic diseases who visit clinics for common cold to avoid the potential inappropriate use of antibiotics and prevent antimicrobial resistance acceleration.

Transdermal Fentanyl Usage in Working-age Patients Undergoing Cancer Treatment: Prescription Pattern Analysis Using Large Claims Data in Japan.

The number of working-age individuals undergoing cancer treatment has been increasing. In these patients, transdermal fentanyl is the preferred treatment. However, it is known to have (1) pharmacodynamic interactions with benzodiazepines and (2) fever-induced pharmacokinetic variations. The aim of this study is to clarify the frequency of co-administration of benzodiazepine and the predictors for fever among working-age patients with cancer using transdermal fentanyl. We used a large claims data source including over 3.6 million patients. Finally, 759 working-age patients aged 20 to 60 years undergoing cancer treatment, in whom transdermal fentanyl was initiated, were analyzed. The proportion of patients receiving co-administration of benzodiazepines with the first administration of transdermal fentanyl was 16.5% (n = 125). This increased to 39.3% (n = 298) within 30 days. Predictive factors for fever using patients' baseline characteristics were male sex, gastrointestinal cancer, hematological cancer, and renal disease. To provide adequate pharmacotherapy to working-age patients undergoing cancer treatment with transdermal fentanyl, medical staff should pay attention to (1) avoid adding benzodiazepines easily and (2) monitor patients having predictors for fever to avoid fentanyl-related adverse events.

[Current Status and the Future of Protection and Utilization of Personal Information at Medical Facilities Based on the Understanding of Related Regulations].

In September 2015, "the Act on the Protection of Personal Information" was amended. Accordingly, "the Ethical Guidelines for Medical Research Involving Human Subjects" were also amended. "The Act on Anonymized Medical Data That Are Meant to Contribute to Research and Development in the Medical Field," which came into effect in May 2018, aims to collect and utilize medical information of each patient from medical institutions for the purpose of research and development in the medical field. Thus, the rules of personal information that need to be followed are changing considerably in the balance between importance of protection and utilization for medical development. Therefore, health care professionals and researchers are required to fully understand the current situation and the future.

Developing a Japanese version of the 'scale of attitudes toward pharmacist-physician collaboration'.

There are many reports that pharmacotherapy has been optimized to ensure collaboration between physicians and pharmacists. Various scales assess the relationship between physicians and pharmacists as well as medical students and pharmacy students. The Scale of Attitudes Toward Physician-Pharmacist Collaboration (SATP2C) can be applied not only to the physician-pharmacist relationship but also to the medical-pharmacy student relationship. As there is no Japanese version of the SATP2C, we developed one and examined its psychometric properties. SATP2C scores were measured before and after interprofessional education (IPE) to verify responsiveness. The scale showed confirmed reliability: Cronbach's alphas were 0.79 for Responsibility and Accountability, 0.68 for Shared Authority, and 0.67 for Interdisciplinary Education. Pre and post-IPE, each mean subscale score increased: Responsibility and Accountability, 0.7 ± 0.4; Shared Authority, 0.2 ± 0.3; and Interdisciplinary Education, 0.3 ± 0.2. Although the total score increased (1.2 ± 0.7), this was non-significant. The Japanese version of the SATP2C can be considered, at least initially, to have reached an acceptable level of reliability and validity. The new measure is currently the only scale in Japan that can evaluate attitudes toward physician-pharmacist collaboration regarding IPE. Further studies are needed to confirm responsiveness pre- and post-IPE.

Economic analysis of palonosetron versus granisetron in the standard triplet regimen for preventing chemotherapy-induced nausea and vomiting in patients receiving highly emetogenic chemotherapy in Japan (TRIPLE phase III trial).

BACKGROUND: We conducted an economic assessment using test data from the phase III TRIPLE study, which examined the efficacy of a 5-hydroxytryptamine 3 receptor antagonist as part of a standard triplet antiemetic regimen including aprepitant and dexamethasone in preventing chemotherapy-induced nausea and vomiting in patients receiving cisplatin-based highly emetogenic chemotherapy (HEC). METHODS: We retrospectively investigated all medicines prescribed for antiemetic purposes within 120 h after the initiation of cisplatin administration during hospitalization. In the TRIPLE study, patients were assigned to treatment with granisetron (GRA) 1 mg (n = 413) or palonosetron (PALO) 0.75 mg (n = 414). The evaluation measure was the cost-effectiveness ratio (CER) assessed as the cost per complete response (CR; no vomiting/retching and no rescue medication). The analysis was conducted from the public healthcare payer's perspective. RESULTS: The CR rates were 59.1% in the GRA group and 65.7% in the PALO group (P = 0.0539), and the total frequencies of rescue medication use for these groups were 717 (153/413 patients) and 573 (123/414 patients), respectively. In both groups, drugs with antidopaminergic effects were chosen as rescue medication in 86% of patients. The costs of including GRA and PALO in the standard triplet antiemetic regimen were 15,342.8 and 27,863.8 Japanese yen (JPY), respectively. In addition, the total costs of rescue medication use were 73,883.8 (range, 71,106.4-79,017.1) JPY for the GRA group and 59,292.7 (range, 57,707.5-60,972.8) JPY for the PALO group. The CERs (JPY/CR) were 26,263.4 and 42,628.6 for the GRA and PALO groups, respectively, and the incremental cost-effectiveness ratio (ICER) between the groups was 189,171.6 (189,044.8-189,215.5) JPY/CR. CONCLUSIONS: We found that PALO was more expensive than GRA in patients who received a cisplatin-based HEC regimen.

A Standard Intervention Practice to Promote Appropriate Lamotrigine Therapy by Pharmacists.

The dosage and frequency of lamotrigine administration for each patient must be prescribed carefully according to the disease, age, concomitant medications, and administration period. According to Pharmaceuticals and Medical Devices Agency (PMDA) reports, either the number of patients with adverse events caused by the inappropriate use of lamotrigine or the ratio of the patients who have benefited from the Relief System for Adverse Drug Reactions did not change even after the revision of the package insert in 2015. The procedure for auditing lamotrigine prescriptions was standardized to improve patient safety in our hospitals. The efficacy of standardization was evaluated by investigating the patients' records and prescriptions. A total of 77 patients treated with lamotrigine were examined to evaluate the appropriateness of the dosage and frequency of administration as well as the number of prescription enquiries made by pharmacists retrospectively. In addition, the presence of adverse events such as skin rash was examined using medical records. The number of inappropriate cases found and the prescription questions asked by pharmacists during the 24-month period before and after standardization were compared. The rate of inappropriate prescriptions after standardization was significantly lower than that before (12.1 vs. 29%; p<0.05). The rate of prescription questions raised after standardization was significantly higher than that before (37.0 vs. 1.7%; p<0.05). Moreover, there was no adverse event after standardization. Our standardization practice was effective to easily identify inappropriate prescriptions and provide physicians with the appropriate dosage or frequency of administration for the patients.

Expected value of the additional state in evaluating the method of quantification and uncertainty of additional states in an analytical model of grade I hypertension.

BACKGROUND: In the construction of pharmacoeoconomic models, simplicity is desirable for transparency (people can see how the model is built), ease of analysis, validation (how well the model reproduces reality), and description. Few reports have described concrete methods for constructing simpler models. Therefore we focused on the value of additional states and uncertainty in disease models with multiple complications. OBJECTIVES: The objective of this study was to examine the possibility of ranking additional states in disease models with multiple complications using a method for evaluating the quantification and uncertainty of additional states. METHODS: The expected value of additional states (EVAS) was formulated to calculate the value of additional states from the variation between analytic models using the net benefit method, and uncertainty was subtracted from the variation. We also verified the usefulness and availability of this method in grade I hypertension as a verification of the disease model. We assumed that stroke was recognized as an associated complication of hypertension in the basic model. In addition, stroke recurrence, coronary heart disease (CHD), and end-stage renal disease (ESRD) were assumed to represent other complications of hypertension. Ten thousand Monte Carlo simulations were performed, and the probability distribution was assumed to be the beta distribution in clinical parameters. The ranges of clinical parameters were ±6.25%, 12.5%, 25%, and 50% of the standard deviation from the mean value. RESULTS: The EVAS in complications of CHD showed the greatest uncertainty. In contrast, the EVAS of ESRD differed from stroke recurrence in the value ranking by uncertainty. CONCLUSIONS: The EVAS has the potential to determine the ranking of additional states based on the quantitative value and uncertainty in disease models with multiple complications.

[Pharmacoeconomic evaluation of hypothetical over-the-counter angiotensin-converting enzyme (ACE) inhibitors for the prevention of stroke in patients with grade I hypertension].

The effectiveness and safety of angiotensin-converting enzyme (ACE) inhibitors for the treatment of hypertension have been confirmed during long-term use. Therefore, ACE inhibitors were selected as one candidate for the switch from ethical drugs to over-the-counter (OTC) medications. The objective of this study was to perform a cost-effectiveness analysis if ACE inhibitors were switched to OTC medications and used by grade I hypertension patients in Japan. We conducted a cost-effectiveness analysis from a social perspective over a lifetime horizon using a Markov Model in 50-year-old men and women with grade I hypertension. They were divided into 3 groups: 1) untreated group; 2) consultation group visiting a clinic and receiving prescriptions for ACE inhibitors; and 3) OTC group purchasing OTC ACE inhibitors. The cost of OTC medications was estimated based on a previous study of willingness to pay (¥7,237/month). Average life expectancies in both the OTC and consultation groups were 20.20 for men and 22.63 for women, while in the untreated group it was 19.97 for men and 22.47 for women. Incremental costs per expected life-year (ICER) were ¥1,743,557 for men and ¥8,647,069 for women in the OTC group and ¥3,819,861 for men and ¥9,639,844 for women in the consultation group. These results suggest that longer life expectancies can be achieved with ACE inhibitors, and the total cost is decreased using OTC ACE inhibitors compared with ethical drugs. OTC ACE inhibitors therefore appear be a useful alternative for patients who do not have time to visit a clinic regularly.

[Cost comparative analysis of drug therapy for non-steroidal anti-inflammatory drug (NSAID)-induced gastric ulcer in Japan].

Drug selection for the treatment of non-steroidal anti-inflammatory drug (NSAID)-induced gastric ulcer was analyzed pharmacoeconomically. Two patterns consisting of continuation of an NSAID plus administration of the prostaglandin (PG) preparation misoprostol (PG model) for 8 weeks and continuation of an NSAID plus administration of the proton-pump inhibitors omeprazole and lansoprazole (PPI model) for 8 weeks were examined. Decision analysis models were created on the basis of reports of clinical studies and epidemiologic studies relating to the drugs and gastric ulcer, and cost-comparative analyses were conducted based on the number of persons who had ulcer healing as health outcomes. Costs were estimated with respect to health expenditures from the third-party payer (public) perspective. In the case of continuation of an NSAID plus administration of the proton-pump inhibitor omeprazole for 8 weeks, the health outcomes improved and costs were reduced in comparison with continuation of an NSAID plus administration of misoprostol, thus making the administration of omeprazole the dominant choice. With continuation of an NSAID plus administration of lansoprazole for 8 weeks, the cost-savings of lansoprazole were inferior to those of misoprostol. The generic omeprazole product was the most cost-saving among the four drugs (misoprostol, original omeprazole product, generic omeprazole product, and lansoprazole) examined.

[Effect on duration of antibiotic therapy and drug cost by introducing critical pathway for patients with CAP in Japan].

The aim of this study was to assess whether Marrie's critical pathway is an effective approach to reduce the duration of antibiotic intravenous therapy and drug cost in patients with community-acquired pneumonia (CAP) in Japan. We conducted a retrospective cohort study in patients with CAP who were admitted to a community hospital or a university hospital. We collected clinical and economic data from medical records and medical fee receipts and estimated drug cost for switching the dosage form using Marrie's critical pathway. Outcomes of this study were change in duration of intravenous therapy and drug cost. Fifty patients with CAP were selected from two hospitals. Actual days of antibiotic intravenous therapy were 9.5+/-4.2 days; in contrast, estimated days were 1.2+/-3.0 days (p<0.001). Actual drug cost was 37148+/-28791 yen; in contrast, estimated drug cost was 8364+/-18356 yen (p<0.001). Average reduction of days of therapy and drug cost were 8.3 days and 28704 yen, respectively. This study suggests that the implementation of Marrie's critical pathway may be an effective approach to reduce medical resources used for CAP treatment in Japan.
