Using pulse oximeters in care homes for residents with COVID-19 and other conditions: a rapid mixed-methods evaluation

Background: There are over 15,000 care homes in England, with a total of approximately 450,000 beds. Most residents are older adults, some with dementia, and other residents are people of any age with physical or learning disabilities. Using pulse oximetry in care homes can help the monitoring and care of residents with COVID-19 and other conditions. Objectives: To explore the views of care home staff, and the NHS staff they interact with, with regard to using pulse oximetry with residents, as well as the NHS support provided for using pulse oximetry. Design: We carried out a rapid mixed-methods evaluation of care homes in England, comprising (1) scoping interviews with NHS leaders, care association directors and care home managers, engaging with relevant literature and co-designing the evaluation with a User Involvement Group; (2) an online survey of care homes; (3) interviews with care home managers and staff, and with NHS staff who support care homes, at six purposively selected sites; and (4) synthesis, reporting and dissemination. The study team undertook online meetings and a workshop to thematically synthesise findings, guided by a theoretical framework. Results: We obtained 232 survey responses from 15,362 care homes. Although this was a low (1.5%) response rate, it was expected given exceptional pressures on care home managers and staff at the time of the survey. We conducted 31 interviews at six case study sites. Pulse oximeters were used in many responding care homes before the pandemic and use of pulse oximeters widened during the pandemic. Pulse oximeters are reported by care home managers and staff to provide reassurance to residents and their families, as well as to staff. Using pulse oximeters was usually not challenging for staff and did not add to staff workload or stress levels. Additional support provided through the NHS COVID Oximetry @home programme was welcomed at the care homes receiving it; however, over half of survey respondents were unaware of the programme. In some cases, support from the NHS, including training, was sought but was not always available. Limitations: The survey response rate was low (1.5%) and so findings must be treated with caution. Fewer than the intended number of interviews were completed because of participant unavailability. Throughout the COVID-19 pandemic, care homes may have been asked to complete numerous other surveys etc., which may have contributed to these limitations. Owing to anonymity, the research team was unable to determine the range of survey respondents across location, financial budget or quality of care. Conclusions: Using pulse oximeters in care homes is considered by managers and staff to have been beneficial to care home residents. Ongoing training opportunities for care home staff in use of pulse oximeters would be beneficial. Escalation processes to and responses from NHS services could be more consistent, alongside promoting the NHS COVID Oximetry @home programme to care homes. Future research: Further research should include the experiences of care home residents and their families, as well as finding out more from an NHS perspective about interactions with care home staff. Research to investigate the cost-effectiveness of pulse oximetry in care homes, and of the NHS COVID Oximetry @home programme of support, would be desirable.

OMERACT Definitions for Ultrasonographic Pathology and Elementary Lesions Of Rheumatic Disorders Fifteen Years On

Objective. The Outcome Measures in Rheumatology (OMERACT) ultrasound (US) working group (WG) operates research activities for the validation of US as an outcome measurement instrument according to the Filter 2.0 framework Methods. From the onset of the WG research in 2005 through now, original publications on definitions and scoring systems for pathophysiological manifestations and elementary lesions of various rheumatic disorders were reviewed Results. Definitions and scoring systems according to new terminology are provided Conclusions. We have redefined OMERACT definitions of US pathology and elementary lesions as well as scoring systems which are now proposed for OMERACT approval for application in clinical trial

The 2017 EULAR standardised procedures for ultrasound imaging in rheumatology

BACKGROUND: In 2001, the European League Against Rheumatism developed and disseminated the first guidelines for musculoskeletal (MS) ultrasound (US) in rheumatology. Fifteen years later, the dramatic expansion of new data on MSUS in the literature coupled with technological developments in US imaging has necessitated an update of these guidelines.OBJECTIVES: To update the existing MSUS guidelines in rheumatology as well as to extend their scope to other anatomic structures relevant for rheumatology.METHODS: The project consisted of the following steps: (1) a systematic literature review of MSUS evaluable structures; (2) a Delphi survey among rheumatologist and radiologist experts in MSUS to select MS and non-MS anatomic structures evaluable by US that are relevant to rheumatology, to select abnormalities evaluable by US and to prioritise these pathologies for rheumatology and (3) a nominal group technique to achieve consensus on the US scanning procedures and to produce an electronic illustrated manual (ie, App of these procedures).RESULTS: Structures from nine MS and non-MS areas (ie, shoulder, elbow, wrist and hand, hip, knee, ankle and foot, peripheral nerves, salivary glands and vessels) were selected for MSUS in rheumatic and musculoskeletal diseases (RMD) and their detailed scanning procedures (ie, patient position, probe placement, scanning method and bony/other landmarks) were used to produce the App. In addition, US evaluable abnormalities present in RMD for each anatomic structure and their relevance for rheumatology were agreed on by the MSUS experts.CONCLUSIONS: This task force has produced a consensus-based comprehensive and practical framework on standardised procedures for MSUS imaging in rheumatology

THE INFLUENCE OF SURFACE EFFECTS ON THE PYROELECTRIC BEHAVIOUR OF T. G. S. CLOSE TO THE PHASE TRANSITION

Une étude du coefficient pyroélectrique p* a été réalisée pendant une élévation de température à taux constant compris entre 0,03 et 1,5 °C.s-1. On a trouvé que p* varie avec l'épaisseur (quand celle-ci décroît de 3 mm à 0,4 mm, p* décroît 8 fois). Ces variations sont expliquées par l'existence de couches de surface ferroélectriquement inactives. Leur influence doit se manifester dans toute méthode de mesure.From the study of pyroelectric coefficient p* during constant-rate-temperature-increase (0,03-1,5 °C.s-1) its thickness dependence was found (for the thickness decrease from 3 mm to 0,4 mm p* decreases eight times) and explained by the influence of ferroelectrically inactive surface layers. The effect is to be expected at any measuring method

Diagnostic Methods for Planar Optical Waveguides

Basic diagnostic methods for examining planar optical waveguides, namely the mode spectroscopy for determining the propagation constants of waveguide modes and two methods for measurement of attenuation coefficient of a waveguide or loss in some waveguide components, are presented. A promising advanced method — optical coherence-domain reflectometry — is briefly mentioned
