Prescribing of proton pump inhibitors (PPIs) has markedly increased since their inception more than 30 years ago. The increase is related to inappropriate and long-term prescribing of PPIs, associated with a lack of education and unclear prescribing and deprescribing guidelines. The implementation of prescribing stewardship programs influences the reduction and inappropriate use of this medication. The purpose of this review is to address the gaps that exist regarding the use of PPIs along with determining methods for deprescribing. Guidelines and stewardship programs, along with education, are needed to reduce the adverse health effects of long-term PPI therapy. 相似文献

运用市场手段实现医药自然分开的理论探讨 总被引:1,自引:0,他引:1
回顾了韩国、我国台湾和大陆实行医药分开改革的过程,认为我国以往的相关改革陷入了“管制”的思维误区。认为通过制度设计,创造医疗机构门诊处方自由流动的环境,依靠市场竞争形成处方流向结构多元化,可以实现医药自然分开状态。提出了“医药自然分开”、“处方流向结构”和“处方分散度”等新概念。 相似文献

An optic chiasm glioma may cause loss of vision, endocrine disturbances, hydrocephalus and cerebral ischemia due to its proximity to the pituitary, hypothalamus, III ventricle and internal carotids. A 3-month-old infant with optic chiasm glioma developed hypopituitarism and inappropriate secretion of antidiuretic hormone with plasma hypo-osmolality. The cerebrospinal fluid (CSF) protein concentration was markedly elevated. The impairment of fluid absorption via arachnoid villi and peritoneum by the high protein content, and reversed osmotic gradient between protein-rich CSF and hypo-osmolar plasma may have contributed to both nonobstructive hydrocephalus and recurrent ascites following ventriculoperitoneal shunting. Cerebral ischemia from carotid compression may have led to cerebral atrophy. 相似文献

This report describes a patient with an implantable defibrillator who suffered an inappropriate defibrillation shock upon retrieving some food items from his inadequately earthed refrigerator. Noise typical of electrical interference can be observed in the stored electrogram of the episode. The patient was instructed to earth his home appliances, but he decided to avoid his refrigerator altogether, and has had no subsequent shocks. 相似文献

ObjectiveIn nursing homes (NHs), psychoactive medication use has received notable attention, but less is known about prescribing in assisted living (AL). This study examined how antipsychotic and antianxiety medication prescribing in AL compares with NHs.DesignObservational, cross-sectional AL data linked to publicly reported NH measures.Setting and ParticipantsRandom sample of 250 AL communities and the full sample of 3371 NHs in 7 states.MethodsWe calculated the percentage of residents receiving antipsychotics and antianxiety medications. For each AL community, we calculated the distance to NHs in the state. Linear models estimated the relationship between AL prescribing and that of the closest and farthest 5 NHs, adjusting for AL characteristics and state fixed effects.ResultsThe prescribing rate of potentially inappropriate antipsychotics (i.e., excluding for persons with recorded schizophrenia and Tourette syndrome) and of antianxiety medications (excluding for those on hospice) in AL was 15% and 21%, respectively. Unadjusted mean antipsychotic prescribing rates were nominally higher in AL than NHs (14.8% vs 14.6%; P = .056), whereas mean antianxiety prescribing was nominally lower in AL (21.2% vs 22.6%; P = .032). In adjusted analyses, AL rates of antipsychotic use were not associated with NH rates. However, being affiliated with an NH was associated with a lower rate of antipsychotic use [b = −0.03; 95% confidence interval (CI) −0.50 to −0.001; P = .043], whereas antianxiety rates were associated with neighboring NHs’ prescribing rates (b = 0.43; 95% CI 0.16–0.70; P = .002).Conclusions and ImplicationsThis study suggests reducing antipsychotic medication use in NHs may influence AL practices in a way not accounted for by local NH patterns. And, because antianxiety medications have not been the focus of national campaigns, they may be more subject to local prescribing behaviors. It seems advantageous to consider prescribing in AL when efforts are implemented to change NH prescribing, as there seems to be related influence whether by affiliation or region. 相似文献
