The impact of COVID-19 public health restrictions on particulate matter pollution measured by a validated low-cost sensor network in Oxford, UK.

Emergency responses to the COVID-19 pandemic led to major changes in travel behaviours and economic activities with arising impacts upon urban air quality. To date, these air quality changes associated with lockdown measures have typically been assessed using limited city-level regulatory monitoring data, however, low-cost air quality sensors provide capabilities to assess changes across multiple locations at higher spatial-temporal resolution, thereby generating insights relevant for future air quality interventions. The aim of this study was to utilise high-spatial resolution air quality information utilising data arising from a validated (using a random forest field calibration) network of 15 low-cost air quality sensors within Oxford, UK to monitor the impacts of multiple COVID-19 public heath restrictions upon particulate matter concentrations (PM10, PM2.5) from January 2020 to September 2021. Measurements of PM10 and PM2.5 particle size fractions both within and between site locations are compared to a pre-pandemic related public health restrictions baseline. While average peak concentrations of PM10 and PM2.5 were reduced by 9-10 µg/m3 below typical peak levels experienced in recent years, mean daily PM10 and PM2.5 concentrations were only ∼1 µg/m3 lower and there was marked temporal (as restrictions were added and removed) and spatial variability (across the 15-sensor network) in these observations. Across the 15-sensor network we observed a small local impact from traffic related emission sources upon particle concentrations near traffic-oriented sensors with higher average and peak concentrations as well as greater dynamic range, compared to more intermediate and background orientated sensor locations. The greater dynamic range in concentrations is indicative of exposure to more variable emission sources, such as road transport emissions. Our findings highlight the great potential for low-cost sensor technology to identify highly localised changes in pollutant concentrations as a consequence of changes in behaviour (in this case influenced by COVID-19 restrictions), generating insights into non-traffic contributions to PM emissions in this setting. It is evident that additional non-traffic related measures would be required in Oxford to reduce the PM10 and PM2.5 levels to within WHO health-based guidelines and to achieve compliance with PM2.5 targets developed under the Environment Act 2021.

Spiritual care as a dimension of holistic care: a relational interpretation.

This article reports on a phenomenological study undertaken to explore the meaning of spiritual care as described by a group of palliative care professionals. The research process was informed by van Manen's (1990) hermeneutic phenomenological approach. Eight palliative care professionals (nurses, complementary therapists and pastoral carers) were recruited from a community palliative care agency in Melbourne, Victoria, which provided home-based palliative care. All participants were female and came from diverse ethnic backgrounds. Data were collected by in-depth conversational interviews and were analyzed thematically. Two themes emerged: 'a living nexus between spiritual care, spirituality and holism' and 'a world of relationships'. The findings of the study point to the need for healthcare professionals to incorporate spiritual care guidelines into practice in order for palliative care to be truly representative of holistic health care.

The utility of CPD for older adult mental health nurses.

AIM: To investigate how mental health nurses working with older adults perceive the benefits and realities of developing the outcomes of current continuing professional development training into actual clinical practice. METHOD: A structured questionnaire was used with a convenience sample of nursing staff. Qualitative analysis was performed using a grounded theory approach in order to identify emergent themes, concepts and categories of data. Four randomly selected nurses were subjected to a voluntary semistructured interview using the questionnaire as a basis for information gathering. RESULTS: The main reason for attending courses was developing skills. Of those attending courses, 42 per cent of qualified and 35 per cent of unqualified staff had a personal development plan (PDP) or individual performance review (IPR). Significantly, all unqualified staff who had not been on a course had no PDP or IPR. Learning was described as applicable to practice by 85 per cent of unqualified and 70 per cent of qualified staff. However, 28 per cent of unqualified staff and 20 per cent of qualified staff felt their practice had not changed as a result of their learning. CONCLUSION: CPD can be a positive experience, providing nurses with the opportunity to direct their professional development.
