Hydration education: developing, piloting and evaluating a hydration education package for general practitioners.

OBJECTIVES: To (1) assess the hydration knowledge, attitudes and practices (KAP) of doctors; (2) develop an evidence-based training package; and (3) evaluate the impact of the training package. DESIGN: Educational intervention with impact evaluation. SETTING: Cambridgeshire, UK. PARTICIPANTS: General practitioners (GPs (primary care physicians)). INTERVENTIONS: Hydration and healthcare training. MAIN OUTCOME MEASURES: Hydration KAP score before and immediately after the training session. RESULTS: Knowledge gaps of doctors identified before the teaching were the definition of dehydration, European Food Safety Authority water intake recommendations, water content of the human body and proportion of water from food and drink. A face-to-face teaching package was developed on findings from the KAP survey and literature search. 54 questionnaires were completed before and immediately after two training sessions with GPs. Following the training, total hydration KAP scores increased significantly (p<0.001; median (25th, 75th centiles); 32 (29, 34)). Attendees rated the session as excellent or good (90%) and reported the training was likely to influence their professional practice (100%). CONCLUSIONS: The training package will continue to be developed and adapted, with increased focus on follow-up strategies as well as integration into medical curricula and standards of practice. However, further research is required in the area of hydration care to allow policymakers to incorporate hydration awareness and care with greater precision in local and national policies.

The Scottish-Finnish-Swedish PARTNER study of taprostene versus placebo treatment in patients with critical limb ischemia.

AIM: Atherosclerotic peripheral arterial disease is a major health problem in the western world, often manifested as intermittent claudication, affecting 10-20% males above 60 years. Ischemic complications can lead to rest pain, ulceration and gangrene. The treatment of choice for critical limb ischemia (CLI) is vascular reconstruction or endovascular interventions. Medical management with vasodilator antiplatelet prostaglandins, could be considered in patients unsuitable for surgery. Long term follow-up on previous prostaglandin studies has been insufficient to evaluate amputation rates. Hence this study evaluated safety and longer term efficacy of taprostene sodium, a prostacyclin (PGI2) analogue in CLI. The aim of this study was to determine whether Taprostene sodium, a PGI2 analogue, was a safe and effective treatment for CLI. METHODS: This paper reports the data from the Scottish-Finnish-Swedish PARTNER Study Group which consisted of a double-blind placebo controlled multi-centre study evaluating Taprostene compared to placebo. The primary endpoints were pain relief and early ulcer healing response at the end of the four week infusion phase and amputation at six months follow-up. The patients were randomly allocated to receive taprostene or placebo in a two to one randomization of active versus placebo. A total of 111 patients with CLI were recruited. Taprostene was given twice a day over two 2 hour periods for four weeks. The early response was evaluated at the end of the four week infusion phase. In patients with rest pain without ulceration, a positive response was complete pain relief without any requirement for analgesic therapy. However in patients with ulceration, a positive response was defined as a decrease in the ulcer size by >30%. Amputation scores were compared at the end of the 6 months follow-up period for all participants. RESULTS: Seventy-four patients received taprostene and 37 placebo. Overall, 61 male patients were enrolled in the study along with 50 females with 11% more women in the taprostene (active) group. For both patients with and without ulcers there was no statistically significant difference noted in the early response between those receiving taprostene and those receiving placebo infusion. The percentage of patients without any amputations was 43% in the taprostene group compared to 38% in the control group at the end of six months; however, these results were not statistically significant. CONCLUSION: Although a reasonable number of patients enrolled in the study it has not been possible to demonstrate any statistically significant benefit of taprostene over placebo. This may be due to more patients with risk factors for peripheral artery disease (PAD) such as hypertension, diabetes mellitus and cigarette smoking in the actively treated group and also due the increased number of women in the active group who are known to generally respond less favourably to antiplatelet agents.
