The Effectiveness of Integrated Care Pathways for Adults and Children in Health Care Settings: A Systematic Review.

Abstract

Background Integrated Care Pathways (ICPs) are management technologies which formalise multi-disciplinary team-working and enable professionals to examine and address how they articulate their respective roles, responsibilities and activities. They map out a patient’s journey and aim to have: ‘the right people, doing the right things, in the right order, at the right time, in the right place, with the right outcome’. Initially introduced into the health care context in the 1980s in the US, enthusiasm for ICPs now extends across the world. They have been promoted as a means to realise: evidence based practice, clinical governance, continuity of care, patient empowerment, efficiency gains, service re-engineering, role realignment and staff education. While ICPs are now being developed and implemented across international health care arena, evidence to support their use is equivocal and understanding of their ‘active ingredients’ is poor. Reviews of evidence of ICP effectiveness have focused on their use in specific patient populations. However, ICPs are ‘complex interventions’ and are increasingly being implemented for a variety of purposes in a range of organisational contexts. Identification of the circumstances in which ICPs are effective is the first step towards developing hypotheses about their active ingredients and the generative mechanisms by which they have their effects. This review was designed to address a slightly different set of questions to those that typify systematic reviews of ICP effectiveness. Rather than simply asking: ‘Are ICPs effective?’, our concern was to identify the circumstances in which ICPs are effective, for whom and in what contexts. In addition to identifying evidence of ICP effectiveness, the review therefore required attention to the contexts in which ICPs are utilised, the purposes to which they are put and the factors critical to their success. In framing the review in this way we are drawing on the insights afforded by Pawson and Tilley’s realistic evaluation methodology. The underlying rationale for this approach is that if we know and understand how different interventions produce varying effects in different circumstances, we are better able to decide what policies/services to implement in what conditions. Objectives To identify the purposes for which ICPs are effective, for whom and in what contexts; To identify the purposes for which ICPs are not effective, for whom and in what contexts; To produce recommendations on how ICPs should be used in the full range of health care settings. Inclusion Criteria Types of participants The review focused on adults and children that accessed health care settings in which ICPs are used. Types of intervention(s)/phenomena of interest For the purposes of the review, the ICP had to meet the defining characteristics set by the European Pathway Association (EPA): An explicit statement of the goals and key elements of care based on evidence, best practice and patient expectations; Facilitation of communication, coordination of roles, and sequencing of activities of the multidisciplinary care team, patients and their relatives; The documentation, monitoring, and evaluation of variances and outcomes; The identification of the appropriate resources. Here multidisciplinary is taken to refer to the involvement of two or more disciplines. Types of outcomes Outcome measures were determined by the purposes of the studies selected for review and the type of study participant. Specific clinical outcomes were determined by the group of patients for which the ICP was developed. Types of studies To address the aims of the review it was necessary to examine evidence of ICP effectiveness across the full spectrum of contexts in which they are in use. In order to keep the study to a manageable scale we limited its scope to randomised controlled trials (RCTs). All RCTs reported TRUNCATED AT 600 WORDS.
