Preparing nurses to initiate thrombolytic therapy for patients with an acute myocardial infarction - is there a consensus?

Possible effects of a course in cardiovascular nursing on prehospital care of patients experiencing suspected acute coronary syndrome: a cluster randomised controlled trial

BACKGROUND

Current research suggests that nurses can influence the outcome for patients with acute coronary syndrome (ACS). The aim of this study has been to evaluate whether a course in cardiovascular nursing (CVN) can improve ambulance nurses' (ANs') prehospital care of patients experiencing suspected ACS, related to pain intensity.

METHODS

This is a cluster randomised controlled trial that was conducted in the ambulance services. Patients were allocated to one of two groups: in the first group, patients were treated by ANs who had attended the CVN course and in the second group patients were treated by ANs without this qualification. Inclusion criteria were: 1/pain raising suspicion of ACS, and 2/pain score ≥4 on a visual analogue scale (VAS). The primary outcome was the estimated intensity of pain or discomfort according to VAS 15 min after randomisation. Secondary outcomes were estimated intensity of pain or discomfort on admission to hospital and further requirement of pain treatment, as well as symptoms such as paleness and/or cold sweat; nausea and/or vomiting; anxiety, dyspnea, degree of alertness, respiratory depression and aggressiveness. A further secondary outcome measured was survival to 30 days. Lastly, a final diagnosis was made. A total of 38 ANs attended the CVN course. There were 1,747 patients who fulfilled the inclusion criteria.

RESULTS

The pain score did not differ significantly between the two groups fifteen minutes after randomisation (median value of VAS was 4.0 in both groups). On admission to hospital the pain score was significantly lower for patients treated by an AN who had attended the CVN course (n = 332) compared with those treated by an AN who had not attended the course (n = 1,415) (median 2.5 and 3.0 respectively, p = 0.001). The ANs who had attended the course used higher doses of morphine.

CONCLUSIONS

An educational intervention with a CVN course did not relate significantly to more efficient pain relief in suspected ACS during the first 15 min. However, this intervention was associated with more effective pain relief later on in the prehospital setting. Thus, a CVN course for ANs appears to be associated with reduced pain intensity among patients experiencing suspected ACS. This result needs however to be confirmed in further trials.

For Better and For Worse: Quality of Life Impaired in HF Patients as well as in Their Partners

Background: Quality of Life (QOL) is known to be impaired in patients with Heart Failure (HF). The involvement of a key person, most often the spouse, enables the HF patient to manage the medical regimen and therefore to sustain Quality of Life (QOL). Yet little is known on the impact of caring for an HF patient on the QOL of the caregiving partner. This study aims to explore the QOL of partners of HF patients compared to the QOL of the patients.

Methods: The study population consisted of 38 couples of hospitalized HF patients and their partners. The Cantril Ladder of Life was used to rate QOL during hospitalization, with regard to the month prior to hospitalization and as projected 3 years in the future. Demographic and clinical variables were collected by patient interview and chart review.

Results: On a scale from 0–10, QOL scores of partners varied from 5.9 to 6.4. At some point the QOL score of partners was even lower than the QOL scores of HF patients. In the month prior to hospital admission the QOL of partners was significantly higher in comparison to the QOL of HF patients (6.1 vs. 4.9, respectively). However, this reversed during hospital admission, with QOL scores of partners being significantly lower compared to QOL scores of HF patients (5.9 vs. 6.8, respectively), even after correcting for age and gender.

Conclusion: In our study the QOL of partners of HF patients was low. Whether this is explicitly due to having to live with a HF patient is not clear. Further research on what partners actually do and the relationship between being a caregiver and QOL is necessary in order to support these partners in giving optimal care and support.

Thrombolysis Nurses: Time for Review

Thrombolysis remains the most popular means of reperfusion following an acute ST-elevation myocardial infarction in the United Kingdom today. There is a wealth of evidence to support the early provision of thrombolysis care and a number of models of care delivery have been proposed to reduce the time delay from admission to hospital to administration of thrombolytic therapy. The movement of this treatment from the coronary care unit to the emergency department in association with the employment of specialist cardiac nurses has been associated with some time reductions. However the quality of evidence to support the employment of specialist cardiac nurses working outside the coronary care unit is limited. The author provides an overview of the main literature in this area outlining the models of care in operation and argues that there are lessons to be learned for future nursing research.

Advanced nursing directives: integrating validated clinical scoring systems into nursing care in the pediatric emergency department

In an effort to improve the quality and flow of care provided to children presenting to the emergency department the implementation of nurse-initiated protocols is on the rise. We review the current literature on nurse-initiated protocols, validated emergency department clinical scoring systems, and the merging of the two to create Advanced Nursing Directives (ANDs). The process of developing a clinical pathway for children presenting to our pediatric emergency department (PED) with suspected appendicitis will be used to demonstrate the successful integration of validated clinical scoring systems into practice through the use of Advanced Nursing Directives. Finally, examples of 2 other Advanced Nursing Directives for common clinical PED presentations will be provided.

An exploration of the ethical dimensions pertinent to gaining consent for thrombolysis

--This paper explores some of the pertinent ethical principles involved in gaining consent in thrombolysis, relevant to both nurses and paramedics. --It describes ethical concerns regarding this practice. --Two key themes that have been explored are around the issue of autonomy and paternalism. --With nurse-initiated thrombolysis gaining momentum, an awareness of key ethical dimensions is fundamental.

The introduction of nurse-initiated thrombolysis in coronary care

Nurse-initiated thrombolysis has emerged as an organizational strategy to improve the delivery of thrombolytic agents to patients suspected of having an acute myocardial infarction. This article will outline the evolution of nurse-initiated thrombolysis on the coronary care unit in the authors' trust and present data on the critical decision-making skills of those nurses who have expanded their practice. Patients who were assessed, and whose thrombolysis was initiated by a nurse designated to deliver this treatment, had "door-to-needle" times consistent with the current targets of the National Service Framework for Coronary Heart Disease (Department of Health (DoH), 2000). A cardiologist acting as a "gold standard" reviewed the assessments of the first 50 patients seen by nurses able to deliver thrombolysis, finding each treatment decision appropriate. This gives support to the notion that appropriately trained and experienced nurses can assess and make treatment decisions in this acute care situation.
