The provision of safe and effective healthcare remains a profoundly important attribute of a society’s commitment to health for all (1). All Western societies have grappled with concerns about the quality of healthcare in recent decades, for care is neither as safe nor as effective as it can be (2).
The increasing uptake of forms of AI/machine learning (henceforth called AI) into the healthcare environment is a potentially welcome development, offering the potential for more systematised learning with the promise of better care. But what is the evidence that AI contributes to improving the health of our communities, to making care safer, and to delivering it in a more cost effective way? And critically, does it help us to better provide for what really matters to healthcare consumers, through their authentic engagement in the design, delivery, monitoring and evaluation of care? These are fundamentally important considerations if we are to make inroads into improving care quality.
The problem of poor care achieved prominence with the release of the Institute of Medicine’s “Crossing the Quality Chasm” in 2001 (3) but despite significant efforts, little progress has been made in profoundly increasing the quality of care since that time. A seminal 2016 paper suggesting that medical error was the third leading cause of death in the US (4) was controversial, but the authors’ conclusion that medical error as a cause of death requires ‘greater attention’ was unchallenged.
Concerns about quality of care remain, despite significant efforts in most Western countries to improve care through better training and systems knowledge (5), linking quality of care to medical professionalism (6), better provision of healthcare related data (7), and an increasing focus on system level impacts on safety and quality (8). Disappointingly, the sense of many at the front line of care delivery is that these system level changes have had a limited impact on care delivery (9).
More recently, there has been an increasing recognition that compliance based approaches to assuring safety and quality have not had the hoped for impact, with many health jurisdictions now moving towards a continuous improvement regulatory philosophy, perhaps best exemplified by the Australian Commission on Safety and Quality in Healthcare’s approach to embedding continuous improvement within the (Australian) National Safety and Quality Health Service Standards (10).
In most Western healthcare systems, the focus of safety and quality efforts has largely been on the hospital setting, with most of the evidence for patient harm and lack of reliability in healthcare coming from this setting. However, primary care remains in most healthcare systems the first point of contact for people accessing health services (11), so it is problematic that there is little evidence (by comparison with hospital based care) of continuous improvement approaches to quality being embedded in that setting. What evidence there is, points to a focus on patient safety, rather than a broader view of quality (12).
Underpinning all efforts to improve quality of care is a recognition that care is fundamentally a ‘social care contract’ that reflects an ethical principle about maximising benefit whilst minimising harm, and that the contract must be preserved through a range of short and long-term transactions between clinicians and consumers. Improving care requires a deep understanding of these activities, and an ability to profoundly influence factors that impact the process of care. Care is thus at its core, a system of processes that can be measured and modified to improve care delivery and care outcomes.
From a socio-technical perspective, quality of care has historically been defined according to the perspective of the ‘actor’ in the care scenario (e.g., Funders may equate quality with health outcome for funds spent, while clinicians may define quality in technical terms). If we take the ‘social care contract’ perspective, then we see value in understanding quality of care from the perspective of the consumer (13). The Institute for Healthcare Improvement’s ‘Triple Aim’ approach (14) provides a way of thinking about quality which moves us from a series of measurable attributes (e.g., safe, timely, equitable, efficient, effective) to one which has a deeper meaning being based in benefit to individual and society. The Triple Aim approach frames quality as care which improves health outcomes (individual and societal), improves the cost efficiency of care (reflecting the stewardship role that we all have for healthcare) and improves the experience of care (at its core ensuring that care has meaning to the individual and the community).
Framing quality in this way allows us to move beyond thinking about quality in professional terms (e.g., training better clinicians) or structural terms (e.g., building better organisations) and moves it into a systems way of thinking that aims to achieve the social contract of quality of care.
However, our current systems way of thinking about healthcare quality is often framed around the business needs of our organisations (e.g., demand and activity management) rather than including considerations of patient-centred care, potentially leading to management decisions in support of gaming the measurement rather than adopting genuine improvement (15). These are important considerations if our healthcare organisations, including small practices, are to remain viable, but they are somewhat removed from the impact of our care systems on individual and groups of patients/consumers.
The shift to more formalised organisation level clinical governance in the 1990’s (16) has required that organisations and clinicians think about quality in a way that moves beyond the organisational level and focuses on the impact of care on consumers. Clinicians have for many years recognised the importance of ‘quality assurance’ activities—ensuring that care was safe and met professional standards (17)—but this focus has often failed to address the patient experience of care (18). This profoundly important shift to focusing on patient centred care allows a different and more nuanced approach to understanding quality at a macro system, organisational, and clinical service level.
Our current understanding of AI suggests that it can potentially assist in improving safety and quality of healthcare through maximising the effectiveness of some current safety and quality tools/approaches, but its impact in other areas is currently unclear. Further, in order for AI to successfully support improvements in care, it must earn the trust of healthcare consumers and their clinicians.
Table 1 summarises the authors’ perspectives on current potential for AI to assist in safety and quality aspects of healthcare.
A consideration of the potential for AI to assist in some areas of safety and quality work (see table) reveals in the authors’ view currently limited opportunity for AI to directly assist clinicians and consumers to improve care, although we expect this situation to improve.
Why do we believe there is currently somewhat limited scope for AI to assist in improving safety and quality of care? In part this reflects that the immediate changes required are largely human—organisational and behaviour (cultural) change, both recognised as being fundamental improving care (19). While some AI approaches (such as ‘nudging’) can affect human behaviour, their usage in healthcare requires careful consideration of the outcomes desired as a system, and potential for unintended consequences—all within an ethical framework with a particular emphasis on privacy.
As we consider quality in the context of the use of AI becoming more significant, we must also consider whether we have in place effective governance and in particular, clinical governance approaches which can assure our communities of benefit from the introduction of AI into healthcare. We therefore continue to advocate for a governance framework that is suitable for governing AI applications within the context of a human/machine socio-technical system (20).
If AI is to have a significant place in supporting care, it must be integrated into routine practice, and into clinical governance approaches. Parallels can be drawn with the now routine use of (organisational) administrative data sets to inform decision making in relation to clinical practice—the limitations of this data set and the assumptions and adjustments underpinning it must be accounted for and managed (21).
The careful implementation of AI under effective governance models will help lead to safer, more effective care, if it can be operationalised and integrated into existing clinical governance models, so that consumers, clinicians, managers and organisational leaders can have confidence that AI is truly supporting improvement and importantly, to ensure that its deployment does not create unintended negative consequences. Reddy et al. have recently suggested that this could occur by healthcare organisations adopting “a clinical governance committee formulated with specific skills and experience to oversee the introduction and deployment of AI models in clinical care” (20).
Whilst this might be feasible in the very largest hospitals, the majority of healthcare is delivered and received (in most jurisdiction’s healthcare systems) in small organisational settings such as practices and clinics, with often limited management oversight and with few resources to support a sophisticated approach to the uptake of new initiatives. This creates particular challenges for the uptake of AI as part of routine clinical quality work in some settings, particularly in the absence of agreed, industry wide standards for AI.
It is also important to consider how AI approaches may have the potential to help improve quality from the consumer perspective through assisting in enabling the entire patient journey (e.g., advising of appointments, warning of missed medications, checking for conflicting advice, assisting with integration of documentation).
At this stage of AI deployment there is real hope that AI can positively impact on both clinical performance and clinical effectiveness, however we caution that organisations and patients/consumers will need to be careful to ensure that any decisions to implement are grounded in the process of care, are evidence based and supported by a governance system which is alert to the potential for unintended consequences.
The range of articles in this edition provide hope for the future for real gains in clinical safety and quality from the advent of AI into routine healthcare practice through the meaningful, authentic engagement of healthcare consumers in the design, delivery, monitoring and evaluation of properly governed healthcare.
