Background: Due to its late stage of diagnosis lung cancer is the commonest cause of death from cancer in the UK. Existing epidemiological risk models in clinical usage, which have Positive Predictive Values (PPV) of less than 10%, do not consider the temporal relations expressed in sequential electronic health record (EHR) data. We aimed to build a model for lung cancer early detection in primary care using machine learning with deep 'transformer' models on EHR data to learn from these complex sequential 'care pathways'.

Article Synopsis
  • A study analyzed data from over 10,000 patients with acute coronary syndrome (ACS) from 2010 to 2017 to explore the impact of reduced kidney function (eGFR) on treatment and mortality rates.
  • It found that lower eGFR levels were strongly linked to a decrease in invasive treatments like coronary angiography; patients with eGFR <30 were significantly less likely to receive these procedures compared to those with higher eGFR.
  • Additionally, there was a clear connection between lower eGFR and higher 30-day mortality rates, indicating that kidney function plays a critical role in treatment outcomes for ACS patients.

Article Synopsis
  • - This study focused on classifying patients with heart failure (HF) and preserved or mildly reduced ejection fraction into specific phenogroups to improve targeted treatment options.
  • - Researchers analyzed data from over 2,000 patients across five UK hospitals using advanced machine learning techniques and found three distinct phenogroups, each with different clinical traits and survival outcomes.
  • - The findings revealed that survival rates declined from the first phenogroup to the third, highlighting the importance of phenogroup membership in predicting survival better than traditional factors, though it did not predict hospitalisation for HF.

Background: No single biomarker currently risk stratifies chronic obstructive pulmonary disease (COPD) patients at the time of an exacerbation, though previous studies have suggested that patients with elevated troponin at exacerbation have worse outcomes. This study evaluated the relationship between peak cardiac troponin and subsequent major adverse cardiac events (MACE) including all-cause mortality and COPD hospital readmission, among patients admitted with COPD exacerbation.

Methods: Data from five cross-regional hospitals in England were analysed using the National Institute of Health Research Health Informatics Collaborative (NIHR-HIC) acute coronary syndrome database (2008-2017).

Background: Errors in electronic health records are known to contribute to patient safety incidents; however, systems for checking the accuracy of patient records are almost nonexistent. Personal health records (PHRs) enabling patient access to and interaction with the clinical records offer a valuable opportunity for patients to actively participate in error surveillance.

Objective: This study aims to evaluate patients' willingness and ability to identify and respond to errors in their PHRs.

Bronchiectasis is an increasingly common chronic respiratory disease which requires a high level of patient engagement in self-management. Whilst the need for self-management has been recognised, the knowledge and skills needed to do so- and the extent to which patients possess these-has not been well-specified. On one hand, understanding the gaps in people's knowledge and skills can enable better targeting of self-management supports.

Background: Sharing electronic health records with patients has been shown to improve patient safety and quality of care. Patient portals represent a convenient tool to enhance patient access to their own health care data. However, the success of portals will only be possible through sustained adoption by its end users: the patients.

Background: Sharing personal health information positively impacts quality of care across several domains, and particularly, safety and patient-centeredness. Patients may identify and flag up inconsistencies in their electronic health records (EHRs), leading to improved information quality and patient safety. However, in order to identify potential errors, patients need to be able to understand the information contained in their EHRs.

Introduction: A global rise in patient complaints has been accompanied by growing research to effectively analyse complaints for safer, more patient-centric care. Most patients and families complain to improve the quality of healthcare, yet progress has been complicated by a system primarily designed for case-by-case complaint handling.

Aim: To understand how to effectively integrate patient-centric complaint handling with quality monitoring and improvement.

Background: Health care professionals (HCPs) are often patients' first point of contact in what concerns the communication of the purposes, benefits, and risks of sharing electronic health records (EHRs) for nondirect care purposes. Their engagement is fundamental to ensure patients' buy-in and a successful implementation of health care data sharing schemes. However, their views on this subject are seldom evaluated.

Introduction: Self-management interventions are often presented as a way to improve the quality of care for patients with chronic illness. However, self-management is quite broadly defined and it remains unclear which types of interventions are most successful. This review will use the Theoretical Domains Framework (TDF) as a lens through which to categorise self-management interventions regarding which programmes are most likely to be effective and under which circumstances.

Background: Image guidance has been clinically available for over a period of 20 years. Although research increasingly has a translational emphasis, overall the clinical uptake of image guidance systems in surgery remains low. The objective of this review was to establish the metrics used to report on the impact of surgical image guidance systems used in a clinical setting.

Article Synopsis
  • A big hospital in London worked with researchers to make patient safety better and create a fairer safety culture in their organization.
  • They gathered feedback from hospital staff and then put in place seven planned actions to help improve safety from 2016 to 2018.
  • They noticed some good changes, like more staff reporting safety problems and feeling positive about most of the actions taken, showing that good health care rules help make things safer for patients.

Introduction: Providing patients with access to electronic health records (EHRs) has emerged as a promising solution to improve quality of care and safety. As the efforts to develop and implement EHR-based data sharing platforms mature and scale up worldwide, there is a need to evaluate the impact of these interventions and to weigh their relative risks and benefits, in order to inform evidence-based health policies. The aim of this work is to systematically characterise and appraise the demonstrated benefits and risks of sharing EHR with patients, by mapping them across the six domains of quality of care of the Institute of Medicine (IOM) analytical framework (ie, patient-centredness, effectiveness, efficiency, timeliness, equity and safety).

Integrated care aims to organize care around the patient instead of the provider. It is therefore crucial to understand differences across patients and their needs. Segmentation analysis that uses big data can help divide a patient population into distinct groups, which can then be targeted with care models and intervention programs tailored to their needs.
