About me

I started at the University of Stirling working in NMAHP RU (Nursing Midwifery and Allied Health Professionals Research Unit) as an impact research fellow on 1st October 2015. I am particularly interested in ensuring trial and study designs answer health research questions that meet the needs of patients, healthcare professionals and policymakers in the “real world”. Following a degree in nursing from Glasgow, I moved to live in Atlanta, USA (2 years) studying for a MPH at Emory University and then lived in Oslo, Norway. I have more than 15 years research experience working with the Cochrane Collaboration at the Norwegian Branch of the Nordic Cochrane Collaboration focussing on the Methodology of undertaking Cochrane systematic reviews of interventions, then working on the methodology for updating Cochrane reviews at the UK Cochrane Centre for 2 years. My varied experience within trial and health research lead to a successful application in October 2011 at the University of Dundee, to work on an MRC funded doctoral research project “Making trials matter: providing an empirical basis for the selection of pragmatic design choices in clinical trials”.

The Problem
Randomised trials are difficult and costly. Like most things that are hard, the effort expended is only worth it because we hope to make a difference. Sadly, the benefit to potential users such as patients, healthcare professionals and policy makers is often smaller than it should be because trial design decisions reduce the relevance of the trial to users. To maximize the relevance of trial results to users it is recommended that researchers design pragmatic trials, testing their intervention under conditions similar to those found in the real world. PRECIS-2 is a trial design tool which encourages trialists to consider how pragmatic their trial is across nine different domains covering the population in the trial, how the intervention is delivered and the outcomes measured. The tool aims to help ensure researchers match their design decisions to the information needs of those they hope will use the trial results. This research explores the views of those using the results of randomised trials to find out their attitudes towards the different PRECIS-2 domains, pragmatic approaches to clinical trial design and what makes research relevant to primary care. The aim of the study is to improve the design of randomised trials in primary care so they produce results are more relevant to practice.
The Approach
We carried out semi structured interviews with individuals or small groups of people involved in implementing research in primary care. We interviewed people involved with journals, guideline development, research charities, research funders, primary care educators, clinical commissioning groups, GPs and clinical effectiveness research. A thematic analysis of the data from the interviews was carried out using the framework approach.
Findings
We conducted 12 interviews across the target groups. We found differences between the way participants used evidence from trials with those involved in synthesizing evidence for guidelines or reviews encountering different challenges to clinicians applying evidence to practice. Important aspects of trial design included that the populations in trials matched those seen in practice and that trials aiming to inform primary care practice are carried out in primary care settings. PRECIS-2 covers many the design issues raises by our participants as being important to ensure trial results are relevant to primary care. There were differing views on whether a more or less pragmatic approach is required for some PRECIS-2 domains particularly whether trials should restrict the flexibility of how an intervention is delivered beyond what would occur in practice.
Consequences
This work provides insights into how to design randomised trials in primary care so that their results are relevant to practice. The findings are relevant to those designing trials as well as those involved in funding decisions or using the results of randomised trials.

Randomised trials are difficult and costly. Like most things that are hard, the effort expended is only worth it because we hope to make a difference. Sadly, the benefit to potential users such as patients, healthcare professionals and policy makers is often smaller than it should be because trial design decisions reduced the relevance of the trial to users.
PRECIS-2 is a tool designed to help trialists match their design decisions to the information needs of those they hope will use the trial results. PRECIS-2 has a highly visual wheel format with nine design domains including Eligibility, Recruitment, Setting, Organisation and Primary outcome which are scored on a Likert scale from "1" very explanatory - ideal world to "5" very pragmatic just like usual care.
We were keen to discuss with those synthesizing research evidence and those using it to determine how evidence is used and what aspects of trial design are important when deciding whether research is relevant to practice. Qualitative research was undertaken using semi-structured interviews of academic GPs, funders and policymakers. The interviews included questions on attitudes to the nine different PRECIS-2 domains as a tool to judge if a trial's results would be useful.
Framework analysis was used to pull out four key themes: aspects of trial results that are important when assessing evidence; how evidence is used; pragmatic and explanatory attitudes; and using the nine domains of PRECIS-2. These themes will be presented to assist future work to design trials that are fit for purpose.

PRECIS-2 is a tool designed to help trialists match their design decisions to the information needs of those they hope will use the trial results. PRECIS-2 was developed in collaboration with over 80 international trialists, methodologists and others to produce a tool that supports improved design insight for trialists.
PRECIS-2 has a wheel format with nine design domains including Eligibility, Recruitment, Setting and Primary outcome. One domain - Organisation - is explicitly aimed at making trialists consider the resource requirements their intervention will place on health care systems if it were to be rolled out into routine care, the intention being to think about implementation at the design stage. The highly visual presentation makes inconsistent decision-making immediately obvious; it also highlights differences of opinion between trial team members.
The IDEAL framework was created to improve the quality of research in surgery. It is proposed that PRECIS-2 could be part of this framework to design these complex intervention trials. We will present the tool, explain how to use it and show examples of how it has been used already. This work is part of the Trial Forge initiative to improve trial efficiency.

Validity and Reliability of PRECIS-2 – a tool designed to help trialists match their trial design decisions to the needs of those they hope will use the results. Society of Clinical Trials 37th Annual Meeting

PRECIS-2 was developed in collaboration with over 80 international trialists, methodologists, clinicians and policymakers to produce a tool that could improve design insight for trialists. PRECIS-2 has a wheel format with nine design domains. The highly visual presentation increases transparency for the consequences of design decisions.
The original PRECIS tool did not have its validity and reliability formally measured. Rather it was conceptual. We did, however, do this for PRECIS-2. The input of so many individuals to create PRECIS-2 helped ensure face and content validity of the tool. The inter-rater reliability of PRECIS-2 was measured using 19 raters (international trialists from seven countries) who used PRECIS-2 to score a varied sample of 15 RCT protocols. Trials were purposefully selected so that they varied between pragmatic and explanatory approaches, including both drug and non-drug trials. Inter-rater reliability was generally good, with seven of nine domains having an ICC over 0.65. Flexibility (Adherence) and Recruitment had wide confidence intervals but raters found these difficult to rate and wanted more information.
Discriminant validity was tested with two raters using a binary system to independently determine if the trial protocols were more pragmatic or more explanatory. Scores from the 19 raters for the 15 trials were then used as predictors of pragmatism. The results reasonable with better than chance discrimination for all domains although confidence intervals were again wide. Primary outcome was the domain most likely to predict if a trial takes a pragmatic approach with an AUROC of 0.75.
We have succeeded in testing the validity and reliability of PRECIS-2. An elaboration paper and website provide guidance that should make it easier for future users of the tool. PRECIS-2 continues to be tested by trial teams, funders and has potential impact in retrospective and prospective use in health care evaluations.
