BackgroundDrug shortages affect health systems worldwide. Research in community pharmacy has focused on the nature, extent and impact of these shortages on patients and pharmacists. However, pharmacists’ moral reasoning in situations of drug shortages has not been addressed.ObjectiveTo explore the moral reasoning perspectives of Dutch community pharmacists in situations of drug shortages.MethodAn electronic survey was developed around three drug shortage scenarios with a varying impact on patient outcomes: a Contraceptive, a Parkinson's and an Osteoporosis scenario. Pharmacists rated the likelihood of nine handling options and rated and ranked 13 considerations that may have played a role therein. The considerations represented three moral reasoning perspectives (MRPs): a business orientation (BO), a rules and regulations (RR), and a professional ethics (PE) MRP. Principle component analysis (PCA) was used to investigate construct validity of the MRPs. MRP rating and MRP ranking scores measured the relative importance of the different MRPs of pharmacists in the three shortages.ResultsResults from 267 Pharmacists were obtained. They reported mostly similar handling in the three shortages, except for the likelihood to make agreements with prescribers or other pharmacists and regarding the decision to import a product. The PCA analysis confirmed the three MRPs that accounted for 29% of variance in the data. Both the MRP rating and especially the MRP ranking scores indicated that PE-MRP considerations were most influential on pharmacists' intended handling of the shortages. In the Contraceptive and the Osteoporosis scenarios, the relative importance of a BO-MRP was higher than in the Parkinson's scenario.ConclusionPharmacists predominantly reason with a PE-MRP when handling drug shortages. However, this perspective can be compromised when the drug shortage is perceived to have a lower impact on patient outcomes and when alternative drugs or therapy are expensive.  相似文献

Many studies identify the risk factors for joining street gangs, but few explore disengagement. This article provides a systematic review of the factors which contribute to disengagement from gangs. Understanding this area is of paramount importance to developing policy and guiding practitioners working with this population, given the impact this lifestyle has on gang members and society as a whole. Seven academic databases, reference lists of relevant publications, an online search engine and a government database were used to identify relevant studies. Inclusion and exclusion criteria and quality assessment methods were employed. Data were then extracted and synthesised. Of 2515 citations, seven were found to have methodological rigour. The findings suggest there is not one definitive reason for gang exit but rather that multiple factors contribute. Variability was found in the quality scores. The limitations of this review are discussed, along with clinical implications and suggestions for future research.  相似文献

目的 调查郑州市三甲医院急诊科护士的道德困境与职业倦怠的现状,并分析两者之间的相关性。方法 采用便利抽样法选取郑州市5所三甲医院的228名急诊科护士作为研究对象,采用一般资料调查表、中文版护士道德困境量表、护士职业倦怠量表对其进行问卷调查。结果 郑州市三甲医院急诊科护士道德困境总分为(49.41±13.35)分,职业倦怠总分为(63.51±17.25)分。单因素分析显示,不同学历、工作年限的急诊护士的道德困境得分比较,差异均有统计学意义(F=4.830,P=0.015; F=6.302,P=0.001);不同年龄急诊护士的职业倦怠得分比较,差异有统计学意义 (F=8.328,P=0.005),急诊科护士道德困境与职业倦怠呈正关性(r=0.412,P<0.05)。结论 郑州市三甲医院急诊科护士的道德困境与职业倦怠普遍存在,护士的道德困境与职业倦怠呈正相关。  相似文献

Why do people tend to care for upholding principles of justice? This study examined the association between individual differences in the affective, motivational and cognitive components of empathy, sensitivity to justice, and psychopathy in participants (N 265) who were also asked to rate the permissibility of everyday moral situations that pit personal benefit against moral standards of justice. Counter to common sense, emotional empathy was not associated with sensitivity to injustice for others. Rather, individual differences in cognitive empathy and empathic concern predicted sensitivity to justice for others, as well as the endorsement of moral rules. Psychopathy coldheartedness scores were inversely associated with motivation for justice. Moreover, hierarchical multiple linear regression analysis revealed that self-focused and other-focused orientations toward justice had opposing influences on the permissibility of moral judgments. High scores on psychopathy were associated with less moral condemnation of immoral behavior. Together, these results contribute to a better understanding of the information processing mechanisms underlying justice motivation, and may guide interventions designed to foster justice and moral behavior. In order to promote justice motivation, it may be more effective to encourage perspective taking and reasoning than emphasizing emotional sharing with the misfortune of others.  相似文献

Aims: The aim of this qualitative research is to show how the alcohol socialization process – i.e. the ways children and young people get acquainted with alcohol – can generate very diverse experiences and meanings in different cultural contexts.

Method: A total of 16 focus groups were conducted in Italy and Finland, divided by age (4 groups), gender and socio-cultural level. A total of 190 participants took part in the study.

Findings: The findings support the hypothesis that the alcohol socialization process takes place in very different ways and assumes diverse meaning in the two countries involved in the study. In Italy the relationship with alcohol takes place as part of a gradual process and participants’ first memories of drinking alcohol are connected to positive values. In Finland, on the other hand, often the first experiences of drinking overlap with the first experiences of intoxication and alcohol images reflect an ambiguous relation with this substance, closely related to its intoxicating effects.

Conclusions: Results show that the alcohol socialization process can take very different forms and meanings according to a specific drinking cultures. Thus, further comparative research should take into more consideration the implication of these substantial differences.  相似文献

The separate identification of effects due to incentives, selection and preference heterogeneity in insurance markets is the topic of much debate. In this paper, we investigate the presence and variation in moral hazard across health care procedures. The key motivating hypothesis is the expectation of larger causal effects in the case of more discretionary procedures. The empirical approach relies on an extremely rich and extensive dataset constructed by linking survey data to administrative data for hospital medical records. Using this approach we are able to provide credible evidence of large moral hazard effects but for elective surgeries only.  相似文献
