Attitudes regarding mental health nurse prescribing among psychiatrists and nurses: a cross-sectional questionnaire study.

BACKGROUND: In the United Kingdom, mental health nurses (MHNs) can independently prescribe medication once they have completed a training course. This study investigated attitudes to mental health nurse prescribing held by psychiatrists and nurses. METHOD: 119 MHNs and 82 psychiatrists working in South-East England were randomly sampled. Participants completed a newly created questionnaire. This included individual item statements with 6-point likert scales to test levels of agreement which were summated into 7 subscales. RESULTS: Psychiatrists had significantly less favourable, albeit generally positive attitudes than MHNs regarding general beliefs (63% vs. 70%, p<0.001), impact (62% vs. 70%, p<0.001), uses (60% vs. 71%, p<0.001), clinical responsibility (69% vs. 62%, p<0.001) and legal responsibility (71% vs. 64%, p<0.001). More MHNs than psychiatrists believed that nurse prescribing would be useful in emergency situations for rapid tranquilisation (82% vs. 37%, p<0.001), and that the consultant psychiatrist should have ultimate clinical responsibility for prescribing by an MHN (42% vs. 28%, p<0.001). Approximately half of all participants agreed nurse prescribing would create conflict in clinical teams. CONCLUSIONS: The majority of both groups were in favour of mental health nurse prescribing, although significantly more psychiatrists expressed concerns. This may be explained by a perceived change in power balance.

Coronary perfusion during acute myocardial infarction with a combined therapy of coronary angioplasty and high-dose intravenous streptokinase.

Two hundred and sixteen patients with acute myocardial infarction were treated with immediate infusion of high-dose (1.5 million units) intravenous streptokinase followed by emergency coronary angioplasty. The infarct lesion was crossed and dilated in 99% and persistent coronary perfusion after the procedure was achieved in 90% (including 3% with significant residual stenosis). Total in-hospital mortality was 12%. Multivariable analysis showed a higher hospital mortality with cardiogenic shock (41% vs 5% without shock), older age, lower left ventricular ejection fraction, and female sex. Final patency of the infarct-related vessel was determined by follow-up in-hospital cardiac catheterization. Coronary reocclusion occurred in 11% (symptomatic in 7%, treated with emergency angioplasty or bypass surgery; silent in 4%, treated medically). Of the surviving patients with successful initial establishment of infarct vessel patency, 94% were discharged from the hospital with an open infarct artery or a bypass graft to the infarct vessel. There was significant improvement in both ejection fraction (44% to 49%; p less than .0001) and regional wall motion in the infarct zone (-3.0 SD to -2.4 SD; p less than .0001) among patients with persistent coronary perfusion and insignificant residual stenosis at the time of the follow-up cardiac catheterization. Thus, a treatment strategy for acute myocardial infarction that includes immediate administration of streptokinase followed by emergency coronary angioplasty, and coronary bypass surgery when necessary, results in a high rate of early and sustained patency of the infarct-related vessel.
