Background: The British Thoracic Society (BTS) has organised intermittent audits of hospital oxygen use in UK hospitals since 2008. Manual audits are time-consuming and subject to human errors. Oxygen prescribing and bedside observations including National Early Warning Scores (NEWS2 scores) are undertaken within an integrated electronic medical record (EMR) at this hospital.

Article Synopsis
- The study explores a digital intervention aimed at promoting long-term physical activity for weight loss maintenance, emphasizing the importance of using solid design and behavior change theories.
- A secondary analysis of the NoHoW trial involved 766 participants who were evaluated for changes in physical activity levels and motivational factors over six to twelve months.
- The findings revealed that while the initial mediation models showed poor fit, simplified models accounting for different types of motivation performed well, but no significant effects were found linking the intervention's climate directly to long-term physical activity outcomes.
Objective: In this study, the associations between the substitution of sedentary time with sleep or physical activity at different intensities and subsequent weight-loss maintenance were examined.
Methods: This prospective study included 1152 adults from the NoHoW trial who had achieved a successful weight loss of ≥5% during the 12 months prior to baseline and had BMI ≥25 kg/m before losing weight. Physical activity and sleep were objectively measured during a 14-day period at baseline.
Background: The use of digital interventions can be accurately monitored via log files. However, monitoring engagement with intervention goals or enactment of the actual behaviors targeted by the intervention is more difficult and is usually evaluated based on pre-post measurements in a controlled trial.
Objective: The objective of this paper is to evaluate if engaging with 2 digital intervention modules focusing on (1) physical activity goals and action plans and (2) coping with barriers has immediate effects on the actual physical activity behavior.
Background: Despite oxygen being the commonest drug administered to critically ill patients we do not know which oxygen saturation (SpO) target results in optimal survival outcomes in those receiving mechanical ventilation. We therefore conducted a feasibility randomised controlled trial in the United Kingdom (UK) to assess whether it would be possible to host a larger national multi-centre trial to evaluate oxygenation targets in mechanically ventilated patients.
Methods: We set out to recruit 60 participants across two sites into a trial in which they were randomised to receive conservative oxygenation (SpO 88-92%) or usual care (control - SpO ≥96%).
