Background/Aims: Antiplatelet therapy with aspirin and clopidogrel is an important component of the management of acute coronary syndrome, but it also increases the risk of bleeding. There are no formal guidelines about the use of a proton pump inhibitor (PPI) for gastroprotection in patients on clopidogrel. This study assessed how many patients in the Royal Darwin Hospital (RDH) and the Royal Hobart Hospital (RHH) prescribed clopidogrel and at risk of bleeding were co‐prescribed PPIs. Methods: We conducted a retrospective cohort study using a pharmacy database to select all patients commenced on clopidogrel in a 1‐year period. We identified all patients newly prescribed clopidogrel and determined the proportion that had a risk factor for bleeding and also received a PPI. We also assessed the effect of the use of PPIs on the number of reported bleeds. Results: The final study cohort consisted of 385 patients who had been newly prescribed clopidogrel. Of all patients discharged on clopidogrel, 95·6% (368/385) had ≥1 risk factor for bleeding. One hundred and twenty‐eight of these patients [128/368, (34·8%)] were discharged on a PPI. Patients on dual antiplatelet therapy with an additional risk factor for bleeding and not discharged on a PPI were more likely to develop a major bleed than patients on dual antiplatelet therapy without a risk factor for bleeding not discharged on a PPI (11·1% vs. 1·8%; P < 0·01). Patients on dual antiplatelet therapy with an additional risk factor for bleeding not discharged on a PPI had a higher probability (borderline significance) of major bleeding, compared with patients on dual antiplatelet therapy with an additional risk factor for bleeding discharged on a PPI [PPI: 1/60, (1·7%) vs. no PPI: 6/54, (11·1%); P = 0·05]. Conclusions: Our results indicate that PPIs may only lower the probability of major bleeding in patients treated with dual antiplatelet therapy, who possess additional risk factor(s) for bleeding. 相似文献

Objective To characterise the nature of the drug-related problems with warfarin therapy identified in pharmacist-conducted medication reviews during a collaborative post-discharge warfarin management service, with a focus on potentially serious drug interactions. Setting Australian community pharmacy practice. Method Medication review reports submitted by pharmacists to patients?? general practitioners as part of the service were reviewed and the type and clinical significance of the warfarin-associated drug-related problems, and the pharmacists?? recommendations were classified. The prevalence of prescribing of ??potentially hazardous?? warfarin drug interactions was investigated and compared with the frequency of documentation of these interactions in the medication review reports. Main outcome measure The number and nature of warfarin-associated drug-related problems identified and the rate of documentation of ??potentially hazardous?? warfarin drug interactions in the reports from pharmacist-conducted medication reviews. Results A total of 157 warfarin-associated drug-related problems were documented in 109 medication review reports (mean 1.4 per patient, 95% CI 1.3?C1.6, range 0?C5). Drug selection and Education or information were the most commonly identified warfarin-associated drug-related problems; most drug-related problems were of moderate clinical significance. Eight of 23 potentially serious warfarin drug interactions (34.8%) were identified in the medication review reports. Conclusion Pharmacists addressing drug selection and warfarin education drug-related problems during medication reviews may have contributed to the positive outcomes of the post-discharge service. Warfarin drug interactions were frequently identified; however, well-recognised potentially hazardous interactions were under-reported. Improved communication along the continuum of care would permit improved targeting of drug-related problem reporting, especially in relation to preventable drug interactions. 相似文献

What is known and Objective: A previously published asthma intervention used a software application to data mine pharmacy dispensing records and generate a list of patients with potentially suboptimal management of their asthma; in particular, a high rate of provision of reliever medication. These patients were sent educational material from their community pharmacists and advised to seek a review of their asthma management from their general practitioner. The intervention resulted in a 3‐fold improvement in the ratio of dispensed preventer medication (inhaled corticosteroids) to reliever medication (short‐acting beta‐2 agonists). This follow‐up study aimed to determine the long‐term effects of the intervention programme on the preventer‐to‐reliever (P:R) ratio. Methods: The same data mining software was modified so that it could re‐identify patients who were originally targeted for the intervention. Community pharmacists who participated in the previous intervention installed the modified version of the software. The dispensing data were then de‐identified, encrypted and transferred via the Internet to a secure server. The follow‐up dispensing data for all patients were compared with their pre‐ and post‐intervention data collected originally. Results and Discussion: Of the 1551 patients who were included in the original study, 718 (46·3%) were eligible to be included in the follow‐up study. The improved P:R ratio was sustained for at least 12 months following the intervention (P < 0·01). The sustained increase in the P:R ratio was attributed to significant decreases in the average daily usage of reliever medication (P < 0·0001). What is new and Conclusion: The follow‐up study demonstrated a sustained improvement in the ratio of dispensed preventer medication to reliever medication for asthma. The intervention has the potential to show long‐lasting and widespread improvements in asthma management, improved health outcomes for patients, and ultimately, a reduced burden on the health system. 相似文献

Background
Seafarers play an important role in the transmission of communicable diseases. The aim of the present study is to draw information and identify possible gaps on occupational health practices related to seafarers sailing on ships within the European Union Member States (EU MS) with focus on communicable diseases. 相似文献78.
1背景与资料上世纪80和90年代,美国的医院和医生组织投入大量时间和资源进行机构重组,以实现提高组织效率、改善财务绩效水平、机构长期生存、承担社区责任和救治病人的目的。而机构重组的主要趋势是建立“有组织的服务提供体系”,包括建立横向的医院联合体,横向的医生联合体,以及纵向的医院与医生联合体等。到目前为止,在美国开展的大量研究对上述机构重组效果的认识莫衷一是。 相似文献
