A Randomised Controlled Trial to Compare a Nurse Practitioner to Medical Staff in the Preparation of Patients for Diagnostic Cardiac Catheterisation: The Study of Nursing Intervention in Practice (SNIP)

BACKGROUND

A number of initiatives have employed nurses in roles traditionally associated with the medical profession but few have been evaluated in prospective randomised studies. This paper reports the results of a randomised controlled trial to assess the performance of a nurse practitioner (NP), trained to prepare patients for diagnostic cardiac catheterisation.

METHODS

Eligible and consenting patients were randomised to preparation by either the NP or junior medical staff (JMS). The safety outcome measure was the rate of in-hospital major adverse clinical events including death, myocardial infarction and emergency bypass coronary surgery. Other outcome measures included rate of minor adverse events, cardiologist assessment of case preparation and presentation, patient satisfaction and duration of pre-admission clinic.

RESULTS

From April 1997 to May 1998 a series of 355 patients scheduled for elective, day-case, diagnostic cardiac catheterisation were screened. Of these, 345 patients were eligible for the study. A total of 339 patients consented to participate and were randomised. Major adverse clinical events occurred in 0/175 (0%) patients in the NP group and 2/161 (1.2%) patients in the JMS group. (Risk difference = -1.2%, upper boundary of the 95% confidence interval = +2.0%) The cardiologist's evaluation that the patient's preparation was acceptable was high in both groups: NP group 98.3% vs. JMS group 98.8%: P = 1.0). Patient satisfaction, assessed by questionnaire, was greater in the NP group (P = 0.04). The median duration of the pre-admission clinic visit was lower in the NP group 165 min vs. 185 min in the JMS group, P = 0.01).

CONCLUSIONS

The preparation of patients for diagnostic cardiac catheterisation can be safely performed by an appropriately trained NP. This approach may be associated with improved patient satisfaction and reduced clinic duration times.

From Paper to Practice: The Views of Occupational Therapists on the Impact of the National Service Framework for Older People on Practice

Philp (2003) outlined the fundamental role that occupational therapists could have in implementing the National Service Framework (NSF) for Older People and reforming services for older people (Department of Health 2001). A research project was undertaken, which aimed to investigate the views of occupational therapists about the implementation of the policy in order to identify the key areas and issues that have had an impact on practice. The research design was qualitative and took the form of focus groups.

The focus group data were analysed using a long-table analysis method (Krueger and Casey 2000), which identified five key themes: a raised profile of older people's services, a changing delivery of services, a revisiting of occupational therapy core skills, assessment and resource allocation. The emerging themes suggested that the NSF for Older People has had an impact on the practice of the occupational therapists involved in the focus groups.

Development and evaluation of a nurse-led, tailored stroke self-management intervention

Background

Community nurses are well placed to promote and support stroke survivors to engage in self-management. The aim of this study was to develop a stroke self-management intervention that could be tailored towards stroke survivors’ self-management needs, goals and levels of activation, in the first year post-stroke.

Methods

Mixed method study, designed in accordance with the British Medical Research Council’s (MRC) guidance for the development and evaluation of complex interventions. The intervention was developed and evaluated in two phases. The intervention was underpinned by the theoretical concept of patient activation and was developed based on a review of published research on stroke self-management interventions and qualitative interviews and focus groups (phase 1). It was evaluated using qualitative interviews and focus groups with stroke survivors and stroke nurses (phase 2). Participants comprised 26 stroke survivors, between 3 and 12 months post stroke and 16 stroke nurses, from across three NHS Boards in Scotland.

Results

The intervention consisted of a tailored self-management action plan, incorporating an individualised assessment of stroke survivor’s readiness to self-manage (using the Patient Activation Measure), goal setting and motivational interviewing. Evaluation showed that many of the individual components of the intervention were perceived as feasible and acceptable to both stroke survivors and stroke nurses.

Conclusions

To our knowledge, this is the first UK study to explore the use of patient activation as a theoretical underpinning in stroke self-management research and to involve stroke survivors and stroke nurses in the design and development of a tailored, person-centred stroke self-management support intervention. The study findings provide the first step in understanding how to effectively develop and deliver stroke self-management support interventions to stroke survivors living at home in the first year following stroke. Further work is needed to develop and refine the intervention and identify how to effectively embed it into nurses’ routine clinical practice.

Identifying Continence OptioNs after Stroke (ICONS): an evidence synthesis, case study and exploratory cluster randomised controlled trial of the introduction of a systematic voiding programme for patients with urinary incontinence after stroke in secondary care

Background

Urinary incontinence (UI) following acute stroke is common, affecting between 40% and 60% of people in hospital, but is often poorly managed.

Aim

To develop, implement and evaluate the preliminary effectiveness and potential cost-effectiveness of a systematic voiding programme (SVP), with or without supported implementation, for the management of UI after stroke in secondary care.

Design

Structured in line with the Medical Research Council framework for the evaluation of complex interventions, the programme comprised two phases: Phase I, evidence synthesis of combined approaches to manage UI post stroke, case study of the introduction of the SVP in one stroke service; Phase II, cluster randomised controlled exploratory trial incorporating a process evaluation and testing of health economic data collection methods.

Setting

One English stroke service (case study) and 12 stroke services in England and Wales (randomised trial).

Participants

Case study, 43 patients; randomised trial, 413 patients admitted to hospital with stroke and UI.

Interventions

A SVP comprising assessment, individualised conservative interventions and weekly review. In the supported implementation trial arm, facilitation was used as an implementation strategy to support and enable people to change their practice.

Main outcome measures

Participant incontinence (presence/absence) at 12 weeks post stroke. Secondary outcomes were quality of life, frequency and severity of incontinence, urinary symptoms, activities of daily living and death, at discharge, 6, 12 and 52 weeks post stroke.

Results

There was no suggestion of a beneficial effect on outcome at 12 weeks post stroke [intervention vs. usual care: odds ratio (OR) 1.02, 95% confidence interval (CI) 0.54 to 1.93; supported implementation vs. usual care: OR 1.06, 95% CI 0.54 to 2.09]. There was weak evidence of better outcomes on the Incontinence Impact Questionnaire in supported implementation (OR 1.22, 95% CI 0.72 to 2.08) but the CI is wide and includes both clinically relevant benefit and harm. Both intervention arms had a higher estimated odds of continence for patients with urge incontinence than usual care (intervention: OR 1.58, 95% CI 0.83 to 2.99; supported implementation: OR 1.73, 95% CI 0.88 to 3.43). The process evaluation showed that the SVP increased the visibility of continence management through greater evaluation of patients’ trajectories and outcomes, and closer attention to workload. In-hospital resource use had to be based on estimates provided by staff. The response rates for the postal questionnaires were 73% and 56% of eligible patients at 12 and 52 weeks respectively. Completion of individual data items varied between 67% and 100%.

Conclusions

The trial was exploratory and did not set out to establish effectiveness; however, there are indications the intervention may be effective in patients with urge and stress incontinence. A definitive trial is now warranted.
