Inpatient COVID-19 mortality has reduced over time: Results from an observational cohort.

BackgroundThe Covid-19 pandemic in the United Kingdom has seen two waves; the first starting in March 2020 and the second in late October 2020. It is not known whether outcomes for those admitted with severe Covid were different in the first and second waves.MethodsThe study population comprised all patients admitted to a 1,500-bed London Hospital Trust between March 2020 and March 2021, who tested positive for Covid-19 by PCR within 3-days of admissions. Primary outcome was death within 28-days of admission. Socio-demographics (age, sex, ethnicity), hypertension, diabetes, obesity, baseline physiological observations, CRP, neutrophil, chest x-ray abnormality, remdesivir and dexamethasone were incorporated as co-variates. Proportional subhazards models compared mortality risk between wave 1 and wave 2. Cox-proportional hazard model with propensity score adjustment were used to compare mortality in patients prescribed remdesivir and dexamethasone.ResultsThere were 3,949 COVID-19 admissions, 3,195 hospital discharges and 733 deaths. There were notable differences in age, ethnicity, comorbidities, and admission disease severity between wave 1 and wave 2. Twenty-eight-day mortality was higher during wave 1 (26.1% versus 13.1%). Mortality risk adjusted for co-variates was significantly lower in wave 2 compared to wave 1 [adjSHR 0.49 (0.37, 0.65) p<0.001]. Analysis of treatment impact did not show statistically different effects of remdesivir [HR 0.84 (95%CI 0.65, 1.08), p = 0.17] or dexamethasone [HR 0.97 (95%CI 0.70, 1.35) p = 0.87].ConclusionThere has been substantial improvements in COVID-19 mortality in the second wave, even accounting for demographics, comorbidity, and disease severity. Neither dexamethasone nor remdesivir appeared to be key explanatory factors, although there may be unmeasured confounding present.

COVID-19 vaccination intent among London healthcare workers.

BackgroundThe 10-month timeline from conception to regulatory approval of the Pfizer–BioNTech vaccine against SARS-CoV-2 is unprecedented in modern medicine. However, the climate of the pandemic has also seen anti-vaccination sentiments flourish.AimsTo determine the intent to accept COVID-19 vaccination among healthcare workers at a London Hospital Trust and examine variation in uptake between demographic groups.MethodsWe conducted a cross-sectional survey open to staff working at the trust. Staff rated on a five-point scale the likelihood of them accepting COVID-19 vaccination.ResultsWe received 514 responses, representing 16% of the workforce. About 59% of staff intended to seek vaccination, 24% to reject and 17% were unsure. There was significantly reduced intended uptake in females, younger age groups, healthcare assistants, nurses, staff of black ethnic backgrounds and those who rejected influenza vaccination. Safety was the dominant concern.ConclusionsOur study finds COVID-19 vaccinate hesitancy is prevalent among healthcare workers at a London Hospital Trust. It is particularly concerning that hesitancy was highest amongst groups most exposed to COVID-19 and most at risk of severe disease. Reasons behind disparities in uptake must be addressed to protect staff and prevent deepening inequalities within the healthcare workforce.

Changes in Emergency Department Activity and the First COVID-19 Lockdown: A Cross-sectional Study.

IntroductionEmergency department (ED) attendances fell across the UK after the ‘lockdown’ introduced on 23rd March 2020 to limit the spread of coronavirus disease 2019 (COVID-19). We hypothesised that reductions would vary by patient age and disease type. We examined pre- and in-lockdown ED attendances for two COVID-19 unrelated diagnoses: one likely to be affected by lockdown measures (gastroenteritis), and one likely to be unaffected (appendicitis).MethodsWe conducted a retrospective cross-sectional study across two EDs in one London hospital Trust. We compared all adult and paediatric ED attendances, before (January 2020) and during lockdown (March/April 2020). Key patient demographics, method of arrival, and discharge location were compared. We used Systemised Nomenclature of Medicine codes to define attendances for gastroenteritis and appendicitis.ResultsED attendances fell from 1129 per day before lockdown to 584 in lockdown, 51.7% of pre-lockdown rates. In-lockdown attendances were lowest for under-18s (16.0% of pre-lockdown). The proportion of patients admitted to hospital increased from 17.3% to 24.0%, and the proportion admitted to intensive care increased fourfold. Attendances for gastroenteritis fell from 511 to 103, 20.2% of pre-lockdown rates. Attendances for appendicitis also decreased, from 144 to 41, 28.5% of pre-lockdown rates.ConclusionED attendances fell substantially following lockdown implementation. The biggest reduction was for under-18s. We observed reductions in attendances for gastroenteritis and appendicitis. This may reflect lower rates of infectious disease transmission, although the fall in appendicitis-related attendances suggests that behavioural factors were also important. Larger studies are urgently needed to understand changing patterns of ED use and access to emergency care during the coronavirus 2019 pandemic.

Pharmacist’s knowledge regarding the management of overactive bladder in elderly women

ObjectiveAnticholinergic drugs are the mainstay treatment of OAB. Anticholinergic load is the cumulative effect of taking anticholinergic medication. Recent evidence suggests that in the elderly this can have a detrimental affect, with the potential to develop dementia. A previous study found that knowledge of anticholinergic load was lacking in our healthcare professionals.The aim of this study was to assess knowledge of pharmacists, who in the UK have the potential where qualified to prescribe as well as dispense. Study designA questionnaire was formulated based on the previous study. It was sent out to 418 pharmacists from; a south London hospital trust, a south London clinical commissioning group and United Kingdom Clinical Pharmacists Association. ResultsSeventy-five pharmacists completed the questionnaire. Solifenacin and tolterodine was the most popular drug prescribed in the elderly without dementia, whilst mirabegron was the most popular in the elderly with dementia. One pharmacist suggested using oxybutynin. Sixty-two percent discuss anticholinergic load with the patients, 40 % advice prescribers and 42 % consider anticholinergic load when dispensing the drug. Fifteen percent have had patients report confusion/memory loss. Thirty percent know how to assess anticholinergic load. Only 15 % felt dementia was a concern with anticholinergic drugs. Worryingly, 54 % though mirabegron exerted anticholinergic effects. ConclusionThis is the first study looking at pharmacist knowledge on the use of anticholinergic medication for OAB in elderly women. Knowledge amongst all healthcare professionals including pharmacists is lacking and needs to be improved.

Association between ward-transfers and hospital-acquired infection: a study using routine data

Abstract Ward-transfers have become more common as hospital staff balance patient needs with bed availability on specific wards. However, increased movement through the hospital may leave patients more vulnerable to potential infectious pathogen transmission routes via increased exposure to contaminated surfaces and more contacts with individuals. This may increase their risk of hospital-acquired infections (HAIs), an adverse event associated with greater antibiotic resistance, patient costs, morbidity, and mortality. This study aimed to quantify the association between the number of ward-transfers undergone during a hospital spell and the outcome of HAI. As elderly patients comprise a large proportion of hospital users and are a high-risk population for HAIs, analysis was focused on people over 65-years old. A retrospective case-control study was undertaken using data extracted from electronic health records and microbiology cultures of non-elective medical admissions to a London hospital trust between January 2016 and December 2018 (n = 24,439). Logistic regression was used to obtain the odds ratio for developing a HAI as a function of the number of ward-transfers until onset of HAI for cases, or hospital discharge for controls, while controlling for covariates including length of stay, procedures and comorbidities. Each additional ward-transfer increased the odds of developing a HAI by 8% (OR 1.08; 95%CI:1.04-1.12). The hospital is a complex environment, and interventions should be viewed in light of their impact on the system as a whole. These findings indicate that non-essential ward-transfers of elderly patients should be minimised. This may lower the incidence of infections in this population, potentially reduce the number of pathogen transmission routes in hospitals and alleviate staff burden incurred by ward-transfer associated procedures. Key messages We analysed 3 years of patient movement and microbiology data of elderly patients in a London hospital trust. Each ward-transfer increased the risk of developing a hospital-acquired infection by 8%. Reducing the number of non-essential ward-transfers patients undergo may lower the incidence of hospital-acquired infections; the decision to move a patient should therefore be carefully considered.

P66 Standardising strengths of unlicensed medicines in a large London hospital trust

BackgroundA UK national position statement on standardised strengths of unlicensed liquid medicines recommend that when children require unlicensed liquid medications, they should receive the recommended strength. By standardising strengths of these medicines, the risk of errors being made in the doses given to children will be reduced and prevent accidental under and overdoses.1 Our Trust has 4 hospital sites since merging in 2012, we found the process of switching to a standard strength far from simple.MethodsThe strengths of unlicensed liquid medicines listed in the position statement available on the pharmacy dispensing system (JAC) were identified, along with the speciality users. Pharmacy and clinical leads were consulted for agreement to switching to the standardised strengths. Pharmacy procurement identified new products in standardised strengths and products were reviewed for suitability by paediatric pharmacist. A cost impact analysis was carried out. Communication was sent to stakeholders including, doctors, nurses, pharmacy and primary care.Results and DiscussionWe found the standardised strengths of azathioprine, clonazepam, ethambutol, isoniazid, melatonin, omeprazole, phenobarbitone and pyrazinamide strengths were on formulary. Clopidogrel, hydrocortisone, sertraline and tacrolimus liquids are not used. Different strengths of the listed unlicensed liquid medicines were used by different sites and specialties. Lead speciality pharmacists agreed with the standardisation. We identified use of unlicensed products where licensed products are available (sildenafil 20 mg/5 mL and furosemide 5 mg/5 mL). We added the use of these items to our review. We were not able to agree on a single standard strength for some items; the neonatal intensive care unit (NICU) have babies under 500 g who may require furosemide, spironolactone and sildenafil in doses that measure less than 0.1 mL using the recommended strengths. This volume is deemed less than satisfactory to be measured safely1. It has been agreed with the neonatal lead pharmacist that additional strengths of the sildenafil (unlicensed 20 mg/5 mL), spironolactone (unlicensed 10 mg/5 mL) and furosemide (20 mg/5 mL) be available for inpatient NICU use only. The potential for patients to be discharged on the non-standard strength is reduced by specifying ‘Not for discharge - inpatient use only’ on the pharmacy system as well as having them only as NICU stock from medicines distribution. Patients admitted on other strengths will be switched (with consent); to minimise risk pharmacists will ensure carers are aware of the change &amp; correct dose volume to administer and endorse TTAs noting the change in concentration for the GP. Primary care have been engaged with the switch and invited the consultant pharmacist to discuss this at the interface meeting. We were not able to source the recommended midazolam 10 mg/5 mL. The switch to chloral hydrate to 1 g/5 mL was calculated to have a significant cost pressure therefore it was agreed that that we would not change from chloral hydrate 500 mg/5 mL at this time as it is mainly used in the in-patient setting within our Trust. Based on current usage there is an estimated cost saving of over £5 k based on the switch of sodium chloride, sildenafil, furosemide and spironolactone. The impact will be reviewed in 6 months.ConclusionA successful switch requires a team approach but will benefit patient safety and save money.ReferenceThe Neonatal and Paediatric Pharmacists Group (NPPG) and Royal College of Paediatric and Child Health (RCPCH).

A pragmatic observational feasibility study on integrated treatment for musculoskeletal disorders: Design and protocol

Musculoskeletal disorders (MSD) comprise a wide range of conditions, associated with an enormous pain and impaired mobility, and are affecting people's lives and work. Management of musculoskeletal disorders typically involves a multidisciplinary team approach. Positive findings have been found in previous studies evaluating the effectiveness of complementary therapies, though little attention has been paid to evaluating of the effectiveness of integrated packages of care combining conventional and complementary approaches for musculoskeletal conditions in a National Health Service (NHS) setting. To determine the feasibility of all aspects of a pragmatic observational study designed: (1) to evaluate the effectiveness and cost effectiveness of integrated treatments for MSDs in an integrated NHS hospital in the UK; (2) to determine the acceptability of the study design and research process to patients; (3) to explore patients' expectation and experience of receiving integrated treatments. This is an observational feasibility study, with 1-year recruitment and 1-year follow-up, conducted in Royal London Hospital for Integrated Medicine, University College London Hospital Trust, UK. All eligible patients with MSDs newly referred to the hospital were included in the study. Interventions are integrated packages of care (conventional and complementary) as currently provided in the hospital. SF-36™ Health Survey, short form Brief Pain Inventory, Visual Analogue Scale, and modified Client Service Receipt Inventory will be assessed at 4/5 time points. Semi-structured interview/focus group will be carried out before treatment, and 1 year after commence of treatment. We intend to conduct a pragmatic observational study of integrated medical treatment of MSDs at a public sector hospital. It will inform the design of a future trial including recruitment, retention, suitability of the outcome measures and patients experiences.

The effects of a graduated aerobic exercise programme on cardiovascular disease risk factors in the NHS workplace: a randomised controlled trial

BackgroundSufficient levels of physical activity provide cardio-protective benefit. However within developed society sedentary work and inflexible working hours promotes physical inactivity. Consequently to ensure a healthy workforce there is a requirement for exercise strategies adaptable to occupational time constraint. This study examined the effect of a 12 week aerobic exercise training intervention programme implemented during working hours on the cardiovascular profile of a sedentary hospital workforce.MethodsTwenty healthy, sedentary full-time staff members of the North West London Hospital Trust cytology unit were randomly assigned to an exercise (n = 12; mean ± SD age 41 ± 8 years, body mass 69 ± 12 kg) or control (n = 8; mean ± SD age 42 ± 8 years, body mass 69 ± 12 kg) group. The exercise group was prescribed a progressive aerobic exercise-training programme to be performed 4 times a week for 8 weeks (initial intensity 65% peak oxygen consumption (VO2 peak)) and to be conducted without further advice for another 4 weeks. The control was instructed to maintain their current physical activity level. Oxygen economy at 2 minutes (2minVO2), 4 minutes (4minVO2), VO2 peak, systolic blood pressure (SBP), diastolic blood pressure (DBP), BMI, C-reactive protein (CRP), fasting glucose (GLU) and total cholesterol (TC) were determined in both groups pre-intervention and at 4 week intervals. Both groups completed a weekly Leisure Time Questionnaire to quantify additional exercise load.ResultsThe exercise group demonstrated an increase from baseline for VO2 peak at week 4 (5.8 ± 6.3 %) and 8 (5.0 ± 8.7 %) (P < 0.05). 2minVO2 was reduced from baseline at week 4 (-10.2 ± 10.3 %), 8 (-16.8 ± 10.6 %) and 12 (-15.1 ± 8.7 %), and 4minVO2 at week 8 (-10.7 ± 7.9 %) and 12 (-6.8 ± 9.2) (P < 0.05). There was also a reduction from baseline in CRP at week 4 (-0.4 ± 0.6 mg·L-1) and 8 (-0.9 ± 0.8 mg·L-1) (P < 0.05). The control group showed no such improvements.ConclusionThis is the first objectively monitored RCT to show that moderate exercise can be successfully incorporated into working hours, to significantly improve physical capacity and cardiovascular health.

Clinical librarianship in the LISCE project, London

Describes evaluation of the LISCE (Library and Information Support for Clinical Effectiveness) project, at University College London Hospital Trust (2000‐2003). The evaluation used an action research framework as the researcher was also the clinical librarian in two clinical teams. Methods included a reflective practice diary kept by the researcher, questionnaires to all 104 staff in the two departments involved, interviews with ten staff. Findings indicated that the concept of clinical librarianship was accepted by most staff, but team working routines, e.g. for clinical guideline development, took some time to establish. Clinical librarians may need a different set of skills from other health librarians.

Closing the audit loop: the role of a pilot in the development of a fractured neck of femur integrated care pathway

Following the results of several audits of the quality of care of fractured neck of femur patients at a large London hospital Trust, recommendations were made for the development of an Integrated Care Pathway (ICP) for this patient group. A multidisciplinary team was set up with the aim of developing an ICP for fractured neck of femur patients. This team met regularly for five months and a pilot ICP was developed. The audit described in this study was carried out on the pilot ICP over a period of three months. The results showed a 33% reduction in the length of stay. In particular, there was a 30% reduction in those patients with a length of stay of greater than 22 days. There was also an 8% drop in mortality. Overall there were improvements in the achievement of the Royal College of Physicians Standards for these patients. The pilot ICP was extremely useful in evaluating the impact of the ICP on the quality and outcomes of patient care and informed the further development of the ICP. Editor ’s comments. Many orthopaedic nurses are now using ICPs and improving patient outcomes. Many still have the weakness of not including the patient sufficiently in their development. UK Readers need to appreciate that this particular ICP was developed and audited before the SIGN guidelines (2002); ‘Prevention and management of hip fracture in older people No. 56 ’, which would probably have better standards to aim for than the Royal College of Physicians guidelines of 1989.

The effectiveness of intermediate care in a nursing-led in-patient unit

In order to assess the potential for a nursing-led in-patient unit (NLIU) to substitute for a period of care in the acute hospital environment and promote recovery before discharge, a randomised controlled trial was conducted. The setting was an acute inner London hospital trust, part of the UK's national health service. Of patients referred to a NLIU from acute wards, 80 were randomly assigned to usual care (remain in normal hospital system) and 97 to the NLIU (nursing-led care with no routine medical involvement). Patients were identified as medically stable but in need of additional nursing intervention by referring medical staff prior to full nursing assessment of suitability. Outcomes compared included functional dependence (Barthel Index), discharge destination and length of hospital stay. Inputs from nursing, paramedical and medical staff were measured. There was no significant difference in functional independence at discharge ( p>0.05). Patients undergoing usual care stayed in hospital for less time (mean difference 18 days, p<0.01) but the same number of patients were in hospital 90 days after recruitment (23% NLIU, 24% usual care p>0.05) due to re-admissions. The model of care implemented differed considerably from that described in the literature with the NLIU having significantly fewer qualified nurses (RNs). Although the anticipated benefits of the NLIU were not demonstrated, the study does not conclude that the model should be rejected. Factors driving length of stay need to be further investigated, as does the possibility of post-discharge benefits. The NLIU does offer some potential to substitute for acute care but also appears to substitute for a period of primary care.
