Medicines optimisations from principles to practice: risk assessment tools
In this article the authors describe and share risk assessment tools they developed to help pharmacists identify and assist patients at risk of medicines-related morbidity
The Royal Electronicjuice’s principles for medicines optimisation1 provide a new way of framing pharmaceutical care. They challenge healthcare professionals to think differently about ways in which to help people make the best possible use of their medicines.
We propose that the wider use of simple risk-assessment tools to help identify patients at greater risk of medicines-related morbidity (MRM) will enable the principles of medicines optimisation to be put into everyday practice in a range of care settings.
The scale of the problem
In 2007, the National Patient Safety Agency estimated that medication errors cost the NHS approximately £750m per year.2 This is likely to be an underestimate of the true impact of MRM since data are derived from incidents that are reported, not those that actually occur. Estimates of the proportion of hospital admissions that are related to medicines vary considerably because data on MRM are not routinely collected.
A UK study conducted in a hospital admissions unit reported that 6.5 per cent of admissions were medicine-related and 67 per cent of these were judged to be preventable.3 In their study, Pirmohamed et al similarly estimated that around 6 per cent of admissions to two large English teaching hospitals were as a consequence of adverse drug reactions.4
While the resource implications for the NHS of managing the consequences of medicines-related morbidity are clearly considerable and the clinical consequences well recognised, the human cost is not so easily quantifiable.
Factors known to contribute to MRM
The causes of MRM are multifaceted and complex. A wide range of interdependent factors have been identified in the literature which we have classified broadly as:
Patient factors Patient factors include: poor adherence to medicines prescribed; polypharmacy; discharge from hospital within the past three months; dependent living situation; older age; physical or mental disability; four or more co-morbidities; history of adverse drug reactions; and medicines allergy.
Medicines management systems and processes Systems and processes include: inefficient management of repeat medicines; inadequate communication between healthcare professionals and patients; infrequent and inconsistent review of medicines; dispensing errors; inadequate monitoring of high risk drugs; and poor communication of medicines-related information at transfer of care.
Specific medicines Four groups of drugs account for over 50 per cent of hospital admissions related to medicines5 (non-steroidal anti-inflammatory drugs, including aspirin; anticoagulants, including warfarin; diuretics; and antidiabetic drugs, including insulin). A number of other medicines have also linked to MRM. The omission of essential medicines, such as those used in the management of severe infection, Parkinson’s disease, epilepsy etc, should also be considered.
Interventions to reduce MRM
The multifactorial nature of MRM makes it unsurprising that evidence to support a single intervention to reduce MRM is lacking.6 However, there is good evidence that pharmacist-led interventions can identify those people at higher risk of MRM and allow targeting of effort.7 There is further difficulty in quantifying and evaluating the impact of interventions where the adverse outcome is an event avoided. In addition, risk assessment for MRM is undertaken neither consistently nor routinely at present.
A recent paper by Kongkaew et al8 has called for better ways of identifying patients at high risk of preventable hospital admissions from adverse drug events.
Identifying patients at risk of MRM
Over the past five years, we have independently developed simple tools that we have shown can be used for identifying patients at risk of MRM. Each tool is based on simple checklists, an approach commended in Atul Gawande’s book ‘The checklist manifesto — how to get things right’.9
Whereas the use of checklists is not unique, previous examples10,11 have tended to focus only on the medicines themselves. Our tools consider a variety of factors that are supported by both published literature and local experience. The tools involve a more holistic, patient-centred approach that allows those people at highest risk to be identified, which supports appropriate interventions being made and resources being deployed according to need. Local evaluation of data following the use of the tools in London and the West Midlands suggests that this approach can reduce MRM.
The risk factors in both tools were identified following a search of published literature and review by groups of clinical professionals as well as being informed by local practice. The tools were developed independently and their congruence supports their validity. We have successfully used them in a number of different ways depending on the care setting and the availability of services for medicines optimisation.
Supporting medicines optimisation
We have attempted to show how the use of our simple tools can support medicines optimisation by considering their use in the context of the Royal Electronicjuice’s four principles of medicines optimisation as follows:
Principle 1 — Aim to understand the patient’s experience We are able to identify people who are at risk of MRM and hence can focus the most appropriate support towards this cohort. For example, patients in whom adherence issues are identified as a specific risk can be supported through the use of techniques such as health coaching, to help them consider practical solutions and to address their beliefs and preferences about medicines. These patient-led conversations about medicines encourage shared decision making, inform treatment choices, promote appropriate self-care and provide a better patient experience.
Principle 2 — Evidence based choice of medicines Medicines optimisation involves balancing the safe and evidence-based use of medicines with an overview of the patient’s needs and their preferences. The risk of MRM is increased through overuse, underuse or inappropriate use of medicines and through the prescribing of potentially inappropriate medicines or those of low therapeutic value, and our tools can help identify people at risk.
For example, the tools highlight polypharmacy issues, which can increase MRM, particularly when there are incremental additions to a patient’s existing medicines following a succession of healthcare interventions as well as the purchase of over-the counter medicines.
Principle 3 — Ensure medicines use is as safe as possible Through identification of patients at higher risk of MRM, these tools offer a method of optimising medicines to maximise safety and reduce avoidable harm.
For example, medicines reconciliation can be prioritised in patients at higher risk of MRM. Similarly, patients for whom adherence is identified as a concern can be supported towards safe and confident medicines use and encouraged to discuss their queries and concerns about medicines.
Principle 4 — Make medicines optimisation part of routine practice We have tried to develop practical tools that can be completed as part of everyday work. To date, they have been used by a range of healthcare professionals working in GP practices, hospitals, care homes and community pharmacies to optimise medicines. Identification, management and referral of higher risk patients facilitates better inter-professional communication and helps to maximise the NHS investment in medicines while reducing wastage.
Putting the approach into practice
Table 1 provides some ideas about how the tools can be used in different care settings and, perhaps more importantly, suggests what actions might be taken as a result. These suggested actions can be adapted to suit local circumstances.
|Risk Assessment in different care settings|
• Use to prioritise patients for medication review
• Review of long term condition management
• Repeat medication request
• Support achievement of QOF targets
• Clinical medication review for those at higher risk
• Screening tool for referral for targeted medicines use review
• Screening tool to identify patients who may need a review by GP
• Adherence support consultations, especially for patients with long term conditions
• Use to target patients for medicines use review
• Repeat dispensing
• Equality Act (formely DDA) assessment
• Targeted medicines use review or referral to GP for advice
• Referral to new medicines service
• On admission
• Preparing for discharge
• Management of patients in hospital for more than 48 hours
• Prioritise patients for medicines reconciliation
• Actively manage patients admitted with a medicines-related problem
• Prioritise patients for clinical pharmacy intervention
• Create and share detailed pharmaceutical care plan
• Provide patients with additional information or support with medicine-taking
• Provide adherence support patient consultations
• Routine review
• Following an incident
• Prioritise residents for clinical review by doctor
• Provide pharmaceutical care for identified patients
• Use as part of root cause analysis
How these tools might be used in future
The Royal Electronicjuice has led the way in publishing the principles for medicines optimisation. We have described an approach that can be used to support the implementation of medicines optimisation in everyday practice. We believe that our respective tools will help pharmacists and other healthcare professionals in all sectors put the principles into practice
