Beaney T, Clarke J, Barahona M, et al., 2020, A primary care network analysis: natural communities of general practices in London, Publisher: Royal College of General Practitioners, ISSN: 0960-1643
BACKGROUND: Primary care networks (PCNs) are a new organisational hierarchy introduced in the NHS Long Term Plan with wide-ranging responsibilities. The vision is that they represent 'natural' communities of general practices with boundaries that make sense to practices, other healthcare providers, and local communities. AIM: Our study aims to identify natural communities of general practices based on patient registration patterns, using network analysis methods and unsupervised clustering to create catchments for these communities. METHOD: Patients resident in and attending GP practices in London were identified from Hospital Episode Statistics from 2017 to 2018. We used a series of novel methods for unsupervised graph clustering. A cosine similarity matrix was constructed representing similarities between each general practice to each other, based on registration of patients in each Lower Super Output Area (LSOA). Unsupervised graph partitioning using Markov Multiscale Community Detection was conducted to identify communities of general practices. Catchments were assigned to each PCN based on the majority attendance from an LSOA. RESULTS: In total 3 428 322 unique patients attended 1334 GPs in general practices LSOAs in London. The model grouped 1291 general practices (96.8%) and 4721 LSOAs (97.6%), into 165 mutually exclusive PCNs. The median PCN list size was 53 490 and a median of 70.1% of patients attended a general practice within their allocated PCN, ranging from 44.6% to 91.4%. CONCLUSION: With PCNs expected to take a role in population health management and with community providers expected to reconfigure around them, it is vital we recognise how PCNs represent their communities. This method may be used by policymakers to understand the populations and geography shared between networks.
Martin G, Clarke J, Markar S, et al., 2020, How should hospitals manage the backlog of patients awaiting surgery following the COVID-19 pandemic? A demand modelling simulation case study for carotid endarterectomy
<jats:p>BackgroundThe COVID-19 pandemic presents unparalleled challenges for the delivery of safe and effective care. In response, many health systems have chosen to restrict access to surgery and reallocate resources; the impact on the provision of surgical services has been profound, with huge numbers of patient now awaiting surgery at the risk of avoidable harm. The challenge now is how do hospitals transition from the current pandemic mode of operation back to business as usual, and ensure that all patients receive equitable, timely and high-quality surgical care during all phases of the public health crisis.Aims and MethodsThis case study takes carotid endarterectomy as a time-sensitive surgical procedure and simulates 400 compartmental demand modelling scenarios for managing surgical capacity in the UK for two years following the pandemic.ResultsA total of 7,69 patients will require carotid endarterectomy. In the worst-case scenario, if no additional capacity is provided on resumption of normal service, the waiting list may never be cleared, and no patient will receive surgery within the 2-week target; potentially leading to >1000 avoidable strokes. If surgical capacity is doubled after 1-month of resuming normal service, it will still take more than 6-months to clear the backlog, and 30.8% of patients will not undergo surgery within 2-weeks, with an average wait of 20.3 days for the proceeding 2 years.ConclusionsThis case study for carotid endarterectomy has shown that every healthcare system is going to have to make difficult decisions for balancing human and capital resources against the needs of patients. It has demonstrated that the timing and size of this effort will critically influence the ability of these systems to return to their baseline and continue to provide the highest quality care for all. The failure to sustainably increase surgical capacity early in the post-COVID-19 period will have significant long-term negative impacts on pat
Appelbaum N, Rodriguez Gonzalvez C, Clarke J, 2020, Ideal bodyweight in the precision era: recommendations in obesity require thought for computer assisted prescribing, Archives of Disease in Childhood, Vol: 105, Pages: 516-517, ISSN: 0003-9888
As the prevalence of childhood obesity continues to increase, there has been comparatively slow growth in the literature describing how best to dose obese children. For medications with low lipid solubility where doses are calculated by the total body weight (TBW) of the child, increasing adiposity may lead to the administration of doses well in excess of that required for therapeutic effect, and potentially beyond the safe therapeutic interval of the medication. This concern underlies recommendations to use alternative bodyweight measurements for some medications when dosing obese children.

ObjectivesTo determine the frequency of use and spatial distribution of health record systems in the English National Health Service (NHS). To quantify transitions of care between acute hospital trusts and health record systems to guide improvements to data sharing and interoperability.DesignRetrospective observational study using Hospital Episode Statistics.SettingAcute hospital trusts in the NHS in England.ParticipantsAll adult patients resident in England that had one or more inpatient, outpatient or accident and emergency encounters at acute NHS hospital trusts between April 2017 and April 2018.Primary and secondary outcome measuresFrequency of use and spatial distribution of health record systems. Frequency and spatial distribution of transitions of care between hospital trusts and health record systems.Results21,286,873 patients were involved in 121,351,837 encounters at 152 included trusts. 117 (77.0%) hospital trusts were using electronic health records (EHR). There was limited regional alignment of EHR systems. On 11,017,767 (9.1%) occasions, patients attended a hospital using a different health record system to their previous hospital attendance. 15,736,863 (73.9%) patients had two or more encounters with the included trusts and 3,931,255 (25.0%) of those attended two or more trusts. Over half (53.6%) of these patients had encounters shared between just 20 pairs of hospitals. Only two of these pairs of trusts used the same EHR system.ConclusionsEach year, millions of patients in England attend two or more different hospital trusts. Most of the pairs of trusts that commonly share patients do not use the same record systems. This research highlights significant barriers to inter-hospital data sharing and interoperability. Findings from this study can be used to improve electronic health record system coordination and develop targeted approaches to improve interoperability. The methods used in this study could be used in other healthcare systems that face the
Feather C, Appelbaum N, Clarke J, et al., 2019, Medication errors during simulated paediatric resuscitations: a prospective, observational human reliability analysis, BMJ Open, Vol: 9, Pages: 1-13, ISSN: 2044-6055
Introduction: Medication errors during paediatric resuscitation are thought to be common. However, there is little evidence about the individual process steps that contribute to such medication errors in this context.Objectives: To describe the incidence, nature and severity of medication errors in simulated paediatric resuscitations, and to employ human reliability analysis to understand the contribution of discrepancies in individual process steps to the occurrence of these errors.Methods: We conducted a prospective observational study of simulated resuscitations subjected to video micro-analysis, identification of medication errors, severity assessment and human reliability analysis in a large English teaching hospital. Fifteen resuscitation teams of two doctors and two nurses each conducted one of two simulated paediatric resuscitation scenarios. Results: At least one medication error was observed in every simulated case, and a large magnitude (>25% discrepant) or clinically significant error in 11 of 15 cases. Medication errors were observed in 29% of 180 simulated medication administrations, 40% of which considered to be moderate or severe. These errors were the result of 884 observed discrepancies at a number of steps in the drug ordering, preparation and administration stages of medication use, 8% of which made a major contribution to a resultant medication error. Most errors were introduced by discrepancies during drug preparation and administration. Conclusions: Medication errors were common with a considerable proportion likely to result in patient harm. There is an urgent need to optimise existing systems and to commission research into new approaches to increase the reliability of human interactions during administration of medication in the paediatric emergency setting.

Martin G, Clarke J, Liew F, et al., 2019, Evaluating the impact of organisational digital maturity on clinical outcomes in secondary care in England, npj Digital Medicine, Vol: 2, ISSN: 2398-6352
All healthcare systems are increasingly reliant on health information technology to support the delivery of high-quality, efficient and safe care. Data on its effectiveness are however limited. We therefore sought to examine the impact of organisational digital maturity on clinical outcomes in secondary care within the English National Health Service. We conducted a retrospective analysis of routinely collected administrative data for 13,105,996 admissions across 136 hospitals in England from 2015 to 2016. Data from the 2016 NHS Clinical Digital Maturity Index were used to characterise organisational digital maturity. A multivariable regression model including 12 institutional covariates was utilised to examine the relationship between one measure of organisational digital maturity and five key clinical outcome measures. There was no significant relationship between organisational digital maturity and risk-adjusted 30-day mortality, 28-day readmission rates or complications of care. In multivariable analysis risk-adjusted long length of stay and harm-free care were significantly related to aspects of organisational digital maturity; digitally mature hospitals may not only deliver more harm-free care episodes but also may have a significantly increased risk of patients experiencing a long length of stay. Organisational digital maturity is to some extent related to selected clinical outcomes in secondary care in England. Digital maturity is, however, also strongly linked to other institutional factors that likely play a greater role in influencing clinical outcomes. There is a need to better understand how health IT impacts care delivery and supports other drivers of hospital quality.
Warren L, Clarke J, Arora S, et al., 2019, Transitions of care across hospital settings in patients with inflammatory bowel disease, World Journal of Gastroenterology, Vol: 25, Pages: 2122-2132, ISSN: 1007-9327
BACKGROUNDInflammatory bowel disease (IBD) is a chronic, inflammatory disorder characterised by both intestinal and extra-intestinal pathology. Patients may receive both emergency and elective care from several providers, often in different hospital settings. Poorly managed transitions of care between providers can lead to inefficiencies in care and patient safety issues. To ensure that the sharing of patient information between providers is appropriate, timely, accurate and secure, effective data-sharing infrastructure needs to be developed. To optimise inter-hospital data-sharing for IBD patients, we need to better understand patterns of hospital encounters in this group.AIMTo determine the type and location of hospital services accessed by IBD patients in England.METHODSThis was a retrospective observational study using Hospital Episode Statistics, a large administrative patient data set from the National Health Service in England. Adult patients with a diagnosis of IBD following admission to hospital were followed over a 2-year period to determine the proportion of care accessed at the same hospital providing their outpatient IBD care, defined as their ‘home provider’. Secondary outcome measures included the geographic distribution of patient-sharing, regional and age-related differences in accessing services, and type and frequency of outpatient encounters.RESULTSOf 95055 patients accessed hospital services on 1760156 occasions over a 2-year follow-up period. The proportion of these encounters with their identified IBD ‘home provider’ was 73.3%, 87.8% and 83.1% for accident and emergency, inpatient and outpatient encounters respectively. Patients living in metropolitan centres and younger patients were less likely to attend their ‘home provider’ for hospital services. The most commonly attended specialty services were gastroenterology, general surgery and ophthalmology.CONCLUSIONTransitions of care between secondary care sett

Clarke JM, Warren LR, Arora S, et al., 2018, Guiding interoperable electronic health records through patient-sharing networks, npj Digital Medicine, Vol: 1, Pages: 65-65, ISSN: 2398-6352
Effective sharing of clinical information between care providers is a critical component of a safe, efficient health system. National data-sharing systems may be costly, politically contentious and do not reflect local patterns of care delivery. This study examines hospital attendances in England from 2013 to 2015 to identify instances of patient sharing between hospitals. Of 19.6 million patients receiving care from 155 hospital care providers, 130 million presentations were identified. On 14.7 million occasions (12%), patients attended a different hospital to the one they attended on their previous interaction. A network of hospitals was constructed based on the frequency of patient sharing between hospitals which was partitioned using the Louvain algorithm into ten distinct data-sharing communities, improving the continuity of data sharing in such instances from 0 to 65–95%. Locally implemented data-sharing communities of hospitals may achieve effective accessibility of clinical information without a large-scale national interoperable information system.

IntroductionThe Clinical Practice Research Datalink (CPRD) is a large electronic dataset of primary care medical records. For the purpose of epidemiological studies, it is necessary to ensure accuracy and completeness of cancer diagnoses in CPRD.MethodCases included had a colorectal, oesophagogastric (OG), breast, prostate or lung cancer diagnosis recorded in a least one of CPRD, Cancer Registry (CR) or Hospital Episodes Statistics(HES) between 2000 and 2013. Agreement in diagnosis between the datasets, difference in dates, survival at one and five-years, and whether patient characteristics differed according to the dataset or the timing of diagnosis were investigated.Results116,769 patients were included. For each cancer, approximately 10% of cases identified from CPRD or HES were not confirmed in the CR. 25.5% colorectal, 26.0% OG, 8.9% breast, 32.0% lung and 18.6% prostate cases identified from the CR were missing in CPRD. The diagnosis date was recorded later in CPRD compared with CR for each cancer, ranging from 81.1% for prostate to 59.6% for colorectal, especially if the diagnosis was an emergency. Compared with the CR and HES, the adjusted risk of a missing diagnosis in CPRD was significantly higher if the patient was older, had more co-morbidities or was diagnosed as an emergency. Survival at one and five-years was highest for CPRD.ConclusionPatient demographics and the route of diagnosis impact the accuracy of cancer diagnosis in CPRD. Although CPRD provides invaluable primary care data, patients should ideally be identified from the CR to reduce bias.

It is often not possible to weigh children upon arrival at an emergency room before commencing the provision of emergency care. Because drugs for children are prescribed on the basis of age and body weight, estimations of weight are necessitated. Age-based equations have been one of the most commonly used weight estimation strategies historically. Due to the variability of weight for age in children, and variations in body habitus, these methods are inaccurate by design (Young and Korotzer, 2016) [1].
Appelbaum N, Clarke J, Maconochie I, et al., 2017, Paediatric weight estimation by age in the digital era: optimising a necessary evil., Resuscitation, Vol: 122, Pages: 29-35, ISSN: 0300-9572
BACKGROUND: Age-based weight estimation methods are regularly used in paediatric emergency medicine despite their well-established inaccuracy. AIM: Determine the potential improvement in accuracy achievable by the use of a new mobile application, based on CDC/WHO weight-for-age centile data, which incorporates a gender assignment, a body habitus assessment, and which is capable of an age-in-months based calculation. METHODS: A theoretical, simulated validation study, comparing the performance of the widely used APLS/EPALS formulae against two contemporary habitus-adjusted methods, and the Helix Weight Estimation Tool. 1,070,743 children from the 2015/2016 UK National Child Measurement Program dataset, aged between 4 and 5 and 11 and 12 years, had age-based weight estimates made by all five methods. RESULTS: Primary outcomes were the percentage of weight estimations within 10%, 20%, and those greater than 20% discrepant from actual weight for each method. Our theoretical, gender-dependent, habitus-adjusted method performed better than all other methods across all error thresholds. The overall number of estimations within 10% was 70.4%, and within 20% was 95.45%. The mean percentage error was -1% compared to actual weight. CONCLUSION: The use of a digital tool incorporating a subjective assessment of body habitus, gender assignment, and the ability to estimate weight based on age-in-months might be able optimise the process of paediatric weight estimation by age, making this practice as safe and accurate as possible for the occasions when weight estimation by age is chosen over length-based methods.

Houston J, Barker W, Clarke J, et al., 2014, Sharing knowledge, saving time: an online toolbox to aid junior doctors., BMJ Qual Improv Rep, Vol: 2, ISSN: 2050-1315
Junior doctors are too often frustrated by not being able to quickly find information for how to make referrals, book investigations and contact other professionals at hospital. To make matters worse, much of the knowledge gained by doctors throughout the year is lost during the August rotation. There is an unmet need for retaining such knowledge, in order to facilitate a smoother and safer handover. We set up the "Doctors Directory" at our trust; a website run by junior doctors, providing specific, up-to-date information relevant to other junior doctors within the trust. Whilst providing day-to-day information, it also contains a "survival guide" for each hospital firm. We surveyed junior doctors before and after the implementation of this site. 81% of FY1s surveyed have used the site. Of the doctors that had used the site, 94% found it helpful with a mean self reported time saving of 39 minutes a day. Whilst still in its infancy, the site now has mobile access, and has an average of 60 hits a day. Quality improvement projects such as this are readily scalable to other hospitals and have enabled junior doctors to waste less time finding how to do jobs and more time actually getting them done.
