Radiological follow-up of adults hospitalised with pneumonia and SARS-CoV-2 infection, in Bristol UK, during the COVID19 pandemic

For patients with pneumonia and COVID19 repeating chest radiography is recommend in current British Thoracic Society (BTS) guidelines. Over two distinct time periods during the COVID19 pandemic (Aug-Dec 2020, Jun-Aug 2021) we undertook an audit of 829 patients hospitalised with infective radiological change (pneumonia=481, COVID19=348). 654/829 patients (79%) required radiological follow-up under BTS guideline criteria. 414/654 (63%) were planned, 322/654 (49%) occurred and, of patients receiving radiological follow-up, most occurred within BTS timelines (86%). Further audits should be conducted to ensure BTS guidelines adherence, to avoid delay in diagnosing underlying malignancy or chronic lung disease.

Increasing oxygen prescribing during the COVID-19 pandemic

Valid oxygen prescriptions for hospital inpatients have been a long-standing problem and have been described extensively in BMJ Open Quality with numerous quality improvement projects (QIPs) with the aim of improving compliance with oxygen prescribing.The British Thoracic Society recommends that all inpatients should have oxygen target saturation set on admission: this is motivated by risks of both undertreatment and overtreatment with oxygen. The discrepancy between the recommendation and the reality produced a number of interventions studied in QIPs over the past years, all aiming at bringing the local ward teams closer to the target. This has become even more important during the COVID-19 pandemic, where non-standard oxygen saturation targets and oxygen scarcity led hospital systems to rethink their internal guidelines on the subject.We propose three novel interventions to improve compliance: a remote, personally directed email communication to a ward pharmacist, a similar communication to ward nurses, and a remote, personally directed WhatsApp communication to junior ward doctors. We undertake a QIP which compares novel interventions developed in-house with the most successful interventions from oxygen prescribing initiatives that have previously been published by BMJ Open Quality. The main outcome measure was the proportion of patients with valid oxygen prescription on a ward.The series of novel interventions in three plan, do study, act cycles led to improvement in the outcome measure from 0% at baseline to 70% at the end of the QIP. The successful interventions from previous QIPs were ran in parallel on a similar ward and achieved improvement from 17.9% at baseline to 55.6% at the end of the QIP.This QIP demonstrates adapted interventions performed in context of social distancing aimed at members of multidisciplinary team which achieve superiority in increasing proportion of patients with a valid oxygen prescription, when compared with previously described methods from BMJ Open Quality.

Observational study of clinico-radiological follow-up of COVID-19 pneumonia: a district general hospital experience in the UK

Background The British Thoracic Society (BTS) recommends that all patients admitted with COVID-19 pneumonia should have a chest X-ray (CXR) and clinical follow-up at 6 or 12 weeks, depending on the disease severity. Little data is available on long-term CXR follow-up for moderate and severe COVID-19 pneumonia. This study aims to evaluate compliance with clinico-radiological follow-up of patients recovering from COVID-19 pneumonia at a local hospital in the UK, as per the BTS guidance, and to analyse radiological changes at clinical follow-up at 12 weeks, in order to risk-stratify and improve patient outcomes. Methods This is a single-centre retrospective audit of 255 consecutive COVID-19 positive patients admitted to a local hospital in the UK over 5 months between May and October 2020. All CXRs and clinic follow-up at 12 ± 8 weeks were checked on an electronic database. Results Over one in two (131/255) patients had CXR evidence of COVID-19 pneumonia during the initial hospital admission. Half of the patients (60/131) died before CXR or clinic follow-up. Fifty-eight percent (41/71) of the surviving patients had a follow-up CXR, and only two developed respiratory complications- one had residual lung fibrosis, another a pulmonary embolism. Eighty-eight percent (36/41) of the patients had either resolution or improved radiological changes at follow-up. Most patients who had abnormal follow-up CXR were symptomatic (6/8), and many asymptomatic patients at follow-up had a normal CXR (10/12). Conclusions Although there were concerns about interstitial lung disease (ILD) incidence in patients with COVID-19 pneumonia, most of our patients with COVID-19 pneumonia had no pulmonary complications at follow-up with CXR. This emphasises that CXR, a cost-effective investigation, can be used to risk-stratify patients for long term pulmonary complications following their COVID-19 pneumonia. However, we acknowledge the limitations of a low CXR and clinic follow-up rate in our cohort.

Time for change in practice of in-patient oxygen therapy: a period-limited, multidimensional approach to improve oxygen prescription compliance: quality improvement project at Hamad General Hospital, Qatar

Prescription of oxygen therapy has traditionally poor compliance across the globe and mostly given to patients on verbal orders leading to under or overuse. The British Thoracic Society (BTS) guidelines (2017) recommend that oxygen therapy must be prescribed. Our study aimed to assess the prescription practice of oxygen therapy for patients admitted to acute medical assessment unit and general medical wards at Hamad General Hospital, Qatar and to achieve 80% compliance of valid oxygen therapy prescription implementing the quality improvement model against the BTS guidelines.The prescription practice of oxygen therapy was audited between April 2019 and August 2019. Using a Plan, Do, Study, Act (PDSA) model of improvement and multiple interventions was performed in the eight PDSA cycles, including (1) educational sessions for residents/fellows/nurses, (2) introduction of electronic prescription, (3) emails, posters/flyers, (4) nurse-led reminders and (5) re-enforced teaching for new residents. Data were then collected using a questionnaire assessing electronic prescriptions and documentation. Our baseline study regarding oxygen therapy showed limited awareness of BTS guidelines regarding the documentation of initiation and further adjustment of oxygen therapy. There was a lack of compliance with oxygen prescription; none of the patients had a valid prescription on our computer-based prescription (Cerner). The duration, target range and indications of Oxygen therapy were documented in 25% (18/72), 45.8% (33/72) and 42% (30/72) patients, respectively. Oxygen was initiated by communication order only. In a total of 16 weeks period, the repeated PDSA cycles showed significant improvement in safe oxygen prescription practices. Following intervention, oxygen electronic prescription, documentation of indications for oxygen therapy, target oxygen saturation and wean-off plan improved to 93%, 85%, 86 % and 80 %, respectively.We concluded that poor compliance to oxygen therapy Orders is a universal issue, which can be successfully managed using small-scale PDSA cycles to ensure sustained improvement through multidimensional interventions, continuous reinforcement and frequent reassessments.

Severe re-expansion pulmonary edema despite incomplete re-expansion of the lung: a case report

Background Re-expansion pulmonary edema is a rare but potentially fatal (mortality up to 20%) complication of the rapid removal of air, fluid, or other space-occupying lesion from the pleural cavity. This case report highlights the fact that this complication is much more likely to occur when treating large, chronic pneumothoraces, and can occur even if the lung fails to fully re-expand. Case presentation A 49-year-old white British man presented to the emergency department with sudden onset of shortness of breath 5 days prior to admission. A left-sided pneumothorax was suspected on clinical examination, and chest X-ray confirmed a large, left-sided pneumothorax. A 12 French gauge chest drain was inserted and connected to an underwater seal. Shortly after insertion of the drain, the patient’s condition deteriorated rapidly with tachypnea and severe hypoxemia. A diagnosis of re-expansion pulmonary edema was made, and the patient was treated with high-flow oxygen and continuous positive airways pressure. Conclusions This case report serves as a reminder of the morbidity and potential mortality associated with a commonly performed medical procedure, and reveals a lack of clear and precise guidance on the management of large, chronic (> 72 hours) pneumothoraces in the current British Thoracic Society pleural disease guidelines.

EP.TU.785Quality Improvement Project: Improving Oxygen therapy prescription in surgical inpatients

Aims The 2015, British Thoracic Society (BTS) Oxygen audit demonstrated that 42% of hospital inpatients were using Oxygen without a prescription. National and local standards state that Oxygen, as a drug, should be routinely prescribed and checked along with regular medications and VTE risk assessment. Our baseline audit conducted over a two month period on the surgical wards of a large city hospital revealed that 78% of patients were not being prescribed oxygen. We set a SMART aim to increase the percentage of surgical inpatients being prescribed oxygen by 20% each month. Methods We used the trust e-prescription software to record our data, with three-stage verification and subsequent senior analysis of data. The three primary drivers identified were factors intrinsic to the department: lack of standard awareness, education and safety-net to ensure sustainability. To tackle these in-turns, we designed three PDSA cycles: Departmental poster, seminar with induction material, and system checklist notification. Results Following our first PDSA cycle, the mean percentage increased from 22% to 60%. Using projection analysis, we anticipate this to increase to > 75% after the second PDSA cycle, and >95% after PDSA3, with 100% sustainability one year later. Conclusion Our results to-date show that practice standards have improved following our first PDSA cycle, indicating that awareness played an important role. We predict that education will play an equal role; and given the research supporting the implications of checklists, we forecast that this later element will be the ultimatum leading to 100% sustainability of patients receiving oxygen prescription.

Development, validation, and testing of a physiotherapist initiated checklist of items for implementing pulmonary rehabilitation in Nigeria

Objectives: Pulmonary rehabilitation (PR) program is beneficial to patients with chronic respiratory diseases. However, PR services are limited or non-existent in many resource limited settings of the world, including Nigeria. Equally important, is lack of local guidelines or checklists to support the implementation of these programs. This study was aimed at developing, validating, and testing a physiotherapist initiated checklist of items for implementing of PR in Nigeria. Materials and Methods: A panel of experienced cardiopulmonary physiotherapists was constituted to draw-up and agree on a list of items that they consider necessary for implementing of PR. The resulting items were collated as a checklist of items. The checklist was then locally validated by presenting it to a wider group of respiratory health-care professionals including chest physicians, nurses, occupational therapists, dieticians, and clinical psychologists, practicing within the study area. Each item was rated from strongly agree to strongly disagree on 5-point Likert scale. Thereafter, the performance of the items of the checklist was subjected to testing by assessing whether each item was addressed in the British Thoracic Society (BTS) PR guideline. This was done by rating each item with either a “yes,” “no,” or “not fully” to whether our checklists are included and described in the BTS guideline. Supporting evidence profile was also stated for some items, if applicable. Results: A consensus was reached by the panel of physiotherapists to arrive at a 16-item checklist. Each item was further provided with specific details and/or examples that are relevant for instituting PR in a Nigerian setting. All items on the checklist were considered valid by other respiratory health-care professionals, with a rating consensus agreement of between 80% and 100%. Furthermore, the testing of checklists based on inclusion and description in the BTS guideline showed that six items were addressed fully in the BTS guideline (rated “yes”), six were partially addressed (rated “not fully”), while four were not addressed (rated “no”). Conclusion: A checklist of items for the implementation of PR in Nigeria was successfully developed, validated, and tested. Nevertheless, there may be a need to develop a full guideline before instituting PR in view of the potential disparities with existing/established guidelines.

1152 “A Hypoxic Dilemma”- Compliance with Oxygen Prescriptions on The Acute Surgical Take

Aim British Thoracic Society Guidelines state that all patients admitted to hospital should have oxygen targets prescribed to promptly start oxygen therapy should clinical deterioration occur. We aimed to assess oxygen prescribing compliance for new surgical patients. Method We assessed prescription of oxygen in patients admitted on the surgical take, once weekly for 8 weeks looking at target values, route of administration, frequency and appropriate signing and dating. A re-audit was performed after presenting the initial results at a department meeting. Results 61 patients were included. Out of 61, 8 patients had COPD. Only 9 patients had adequate oxygen prescriptions with all the criteria completed. After re-audit, 50 surgical take patients’ drug charts were reviewed. 42 out of 50 patients had correctly completed oxygen prescriptions. Conclusions Correct oxygen administration in high-risk patients is vital in their management, particularly during clinical deterioration. A discernible improvement in prescriptions was noted in this study.

Experiences of early air travel with pneumothorax after anterior spinal surgery

Anterior thoracic or thoracolumbar spinal surgery by retropleural approach always carries a risk of pneumothorax as its consequence. Conventionally, the Aerospace Medicine Association and the British Thoracic Society recommend 2 weeks delay of air travel for a patient with resolved postoperative pneumothorax. They also label active pneumothorax as an absolute contraindication for commercial air travel. Such a delay always causes psychological and financial stress to patients and family who are far from home. Here, we report three patients with postoperative pneumothorax, who insisted on early air travel despite being informed of the possible consequences.
