Improving weekend handover in a teaching hospital elective general surgery department

BackgroundEffective documentation and transfer of clinical information are vital for the continuity of care, patient safety, and maintaining medico-legal records, as outlined by the Royal College of Surgeons “Safe Handover: Guidance from the Working Time Directive working party”. Our elective surgery weekend team cross-covers both Colorectal and Upper Gastrointestinal surgical specialties across multiple wards, which poses a significant challenge. The aim of this study was to improve the documentation of patients' weekend plans through the introduction of a weekend handover proforma.MethodWe reviewed the weekend plans of 199 patients overall. 41 records were initially reviewed over a 2-week period. The surgical multidisciplinary team was then surveyed to establish the need for an improved weekend handover. Following this, a weekend handover proforma was introduced as part of the Friday ward round and education on the expectations were provided at a local Surgery Clinical Governance meeting. The documentation of the weekend plan was reviewed for 158 patients over a 6-week period and a post-intervention survey was disseminated.ResultsThe preliminary survey highlighted concerns for delayed discharges and patient safety over the weekend, with 88.2% of respondents agreeing a weekend handover proforma would be beneficial. The initial data confirmed inadequate documentation of diagnosis (19.5%), operation/procedure (28.1%), and weekend plans for blood tests (19.5%), discharge planning (2.4%), diet (46.3%), antibiotics (19.5%), intravenous (IV) fluids (22.0%), mobility (19.5%) and drain/wound care (37.5%). After education and implementing a weekend handover proforma, these results increased for documentation of diagnosis (61.2%), operation/procedure (83.2%), blood tests (59.7%), and discharge planning (85.8%). However, there was little improvement in diet (53.0%) and no improvement in the weekend plans for antibiotics (14.2%), IV fluids (17.2%), mobility (14.9%) and drain/wound care (20.2%). The post-intervention survey showed an improvement across all areas, notably continuity of care and patient safety, with 95.5% of individuals finding the weekend handover proforma aided in patient care over the weekend.ConclusionEducation of the ward team and implementation of a weekend handover proforma resulted in a marked improvement in the documentation of patients' weekend plans, which is essential to ensure the continuation of safe and effective patient care

The movement ecology of seagrasses

A movement ecology framework is applied to enhance our understanding of the causes, mechanisms and consequences of movement in seagrasses: marine, clonal, flowering plants. Four life-history stages of seagrasses can move: pollen, sexual propagules, vegetative fragments and the spread of individuals through clonal growth. Movement occurs on the water surface, in the water column, on or in the sediment, via animal vectors and through spreading clones. A capacity for long-distance dispersal and demographic connectivity over multiple timeframes is the novel feature of the movement ecology of seagrasses with significant evolutionary and ecological consequences. The space–time movement footprint of different life-history stages varies. For example, the distance moved by reproductive propagules and vegetative expansion via clonal growth is similar, but the timescales range exponentially, from hours to months or centuries to millennia, respectively. Consequently, environmental factors and key traits that interact to influence movement also operate on vastly different spatial and temporal scales. Six key future research areas have been identified

Evolution of long-term vaccine-induced and hybrid immunity in healthcare workers after different COVID-19 vaccine regimens

BACKGROUND: Both infection and vaccination, alone or in combination, generate antibody and T cell responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, the maintenance of such responses-and hence protection from disease-requires careful characterization. In a large prospective study of UK healthcare workers (HCWs) (Protective Immunity from T Cells in Healthcare Workers [PITCH], within the larger SARS-CoV-2 Immunity and Reinfection Evaluation [SIREN] study), we previously observed that prior infection strongly affected subsequent cellular and humoral immunity induced after long and short dosing intervals of BNT162b2 (Pfizer/BioNTech) vaccination. METHODS: Here, we report longer follow-up of 684 HCWs in this cohort over 6-9 months following two doses of BNT162b2 or AZD1222 (Oxford/AstraZeneca) vaccination and up to 6 months following a subsequent mRNA booster vaccination. FINDINGS: We make three observations: first, the dynamics of humoral and cellular responses differ; binding and neutralizing antibodies declined, whereas T and memory B cell responses were maintained after the second vaccine dose. Second, vaccine boosting restored immunoglobulin (Ig) G levels; broadened neutralizing activity against variants of concern, including Omicron BA.1, BA.2, and BA.5; and boosted T cell responses above the 6-month level after dose 2. Third, prior infection maintained its impact driving larger and broader T cell responses compared with never-infected people, a feature maintained until 6 months after the third dose. CONCLUSIONS: Broadly cross-reactive T cell responses are well maintained over time-especially in those with combined vaccine and infection-induced immunity ("hybrid" immunity)-and may contribute to continued protection against severe disease
