The heparin management test: a new device for monitoring anticoagulation during coronary intervention

Whole blood coagulation analysers are widely used during percutaneous coronary interventions. The precise degree of anticoagulation in patients is important in this setting. The aim of this investigation was to compare the results obtained with ACT (Hemochron) and HMT, the Heparin Management Test (TAS) in patients undergoing percutaneous coronary interventions. Patients (n=100) were enrolled prospectively. Each patient received 10,000 units of heparin. At the end of the procedure, the mean ACT was 284±31 seconds and the mean HMT was 292±33 seconds. The correlation between the two methods was highly significant (r=0.64, p<0.001). The HMT correlates well with ACT values in patients undergoing percutaneous coronary interventions. Its use in the management of these patients should be considered.

Coping with rheumatoid arthritis. How can specialist nurses influence it and promote better outcomes?

• ? Psychological stressors are said to be an important influence on the outcome of chronic illnesses such as rheumatoid arthritis (Engel, 1977).
• ? Helping patients to cope with stressors is identified as a central concept in the delivery of nursing care (Khan et al., 1994). It is thus reasonable to suggest that rheumatology nurses may be key players in the process of coping with rheumatoid arthritis.
• ? But in order for rheumatology nurses to be effective players in this process, they need to discourage coping behaviour(s) linked to poor outcomes, and/or promote an overall behaviour pattern linked to a better outcome. Literature showing the link between different coping behaviours and outcome is examined, and cognitive restructuring is emphasized as one method nurses could use.
• ? Having identified coping behaviour which is optimal in terms of future outcome, further study of different forms of coping-based educational intervention is suggested, to reveal how such patterns of behaviour can be taught by nurses in the most effective way

     

"Just using old works": injecting risk behaviour in prison

A minority of injecting drug users engage in high risk injecting behaviours when in prison. In the United Kingdom between a quarter and a third of injectors who enter prison inject when in prison, and of these about three-quarters share needles and syringes. In the present study, 44 drug injectors who had been released from prison for no longer than 6 months were recruited and interviewed in three geographical areas in England. Interviewees were asked to recount their experiences of drug use during their most recent period of imprisonment. The majority of interviewees were male (38/44), had a mean age of 28 years, with a mean age of 16 years at first drug use, were primarily opiate users (39) and had multiple imprisonments. All respondents reported drug use when imprisoned and drug injecting was reported by 16 interviewees. Most injected at irregular intervals and at a reduced level, compared with injecting when in the community. Nine reported using needles and syringes that others had previously used. When considering other injecting equipment, more sharing occurred than was actually reported. Much re-use of equipment was viewed simply as “using old works”. The sharing of “cookers” and “filters”, and drug sharing by “backloading” and “frontloading” were common. The concept of “sharing” tended to be understood by respondents as related to the use of tools of injection (needles and syringes rather than other equipment); the use of tools in the act of injection (rather than for mixing drugs); proximity (multiple use of needles and syringes in the presence of others); temporality (shorter time elapse between consecutive use of needles and syringes previously used by another) and source (hired rather than borrowed or bought). We conclude that syringe sharing is an integral part of drug use and drug injecting in prison. Many of those interviewed displayed a restricted understanding of what denotes syringe sharing. Our data reinforce the need for interventions and initiatives to be developed within prisons to deal with the considerable risk posed by continued injecting drug use.     

社区糖尿病患者量化饮食和运动治疗的疗效观察

目的通过对糖尿病患者进行量化饮食治疗和运动治疗,探索社区糖尿病管理的有效模式,以有效控制血糖,降低医疗费用。方法选取社区内空腹血糖小于11.1mmol/L的2型糖尿病患者129人,按病情匹配分为强化管理组(64例)和普通管理组(65例)。强化管理组采用一对一的指导和监督,量化饮食和运动治疗,有针对性的进行健康教育和心理疏通。普通管理组为一般的健康教育和门诊治疗。观察两组干预一年后的病情控制情况和医药费用的情况。结果强化管理组平均空腹血糖为5.8mmol/L,比普通管理组的7.1mmol/L有明显降低,糖化血红蛋白强化管理组为5.9%,普通管理组为7.0%。强化管理组医药费平均每人每月下降32.25元,下降幅度为20.12%,普通管理组平均每人每月下降12.47元,下降幅度为4.54%。结论量化饮食和运动治疗在社区糖尿病干预中疗效优于普通干预组,且医药费用明显降低。     

Medical Specialization,Profession, and Mediating Beliefs That Predict Stated Likelihood of Alcohol Screening and Brief Intervention: Targeting Educational Interventions

Practitioner-level educational approaches that promote screening and brief intervention (SBI) seldom consider providers' profession and medical specialization. Strategies that consider these variables may be better equipped to affect change in beliefs and behavior. The aim of this study was to identify beliefs that predict stated likelihood of practicing SBI by specialty and health profession in order to guide the direction of educational strategies. Physicians and nurse practitioners were studied that specialized in family, internal, obstetric gynecology (ObGyn), and pediatric medicine. The results indicated that independent of amount of previous postgraduate alcohol education and knowledge, self-rated competence mediated between specialty and likelihood of practicing SBI. For instance, low self-rated competence for ObGyn was a barrier that suppressed likelihood of practicing SBI. Other findings were that role legitimacy mediated the association between profession and likelihood of SBI, so that lack of role legitimacy was a barrier for physicians but not for nurse practitioners. We suggest that targeted educational strategies for ObGyn and pediatric clinicians may prove more effective than the prevalent one-size-fits all approaches aimed at general adult populations.
