In total we followed up 272 patients who were referred to our service.In the first wave (April 2020 - July 2020) we followed up 117 patients of whom 99 had a follow-up chest X-ray. Chest x-rays were performed on average 80.4 (43–140) days post discharge. Of these patients, 14% had residual changes, with 86% having a clinic normal chest X-ray, with 33 (28%) requiring referral for further investigation and respiratory physician follow-up due to breathlessness (quantified by Modified Medical Council Research dyspnoea score) identified at follow-up clinic appointments, on average 168.4 (91–209) days post discharge.In the second wave (October 2020 – April 2021) we followed up 155 patients of whom 133 had a chest x-ray and 51 (38%) had residual changes.

Technology can assist clinical teams to deliver comprehensive care in the community. In this study we aim to evaluate the safety and effectiveness of an innovative, telehealth-led virtual ward for Covid-19.MethodsPatients discharged from hospital respiratory wards with a diagnosis of Covid-19 and deemed at risk of readmission (or requiring home oxygen weaning) were eligible for referral. Monitoring equipment (thermometers and digital pulse oximeters) was provided and patients were on-boarded into a telehealth platform prior to discharge. Smartphones and tablets were supplied by the service if required. A Covid-19 digital clinical question set and triaging algorithm was developed locally. Patients were instructed to complete it daily remotely during follow-up and to enter their observations three times daily. Clinical data fed into a dashboard reviewed daily by the community respiratory specialist team who would contact and assess patients submitting symptoms of concern. Monitoring lasted for up to 14 days, and escalation processes to the acute Trust were in place for those patients showing evidence of deterioration.Results218 patients were monitored between December 2020 and May 2021, 29 for oxygen weaning. 41% were female, mean age 57 years old (minimum 21, maximum 89). Average oxygen weaning time was 11 days, with 319 days of hospital bed days saved by the oxygen weaning service and an estimated £127,600 cost saving to the system. Only 10 patients (4.9%) were readmitted after 14 days (versus 9% in usual care from hospital Covid-19 wards). Four patients (1.8%) died in hospital after a readmission. 83% of patients felt ‘very supported’ by the service and 73% expressed that it had ‘fully’ improved their confidence. Average score of satisfaction with the service, measured by a self-reported questionnaire, was 9.9/10.ConclusionsA telehealth-assisted remote monitoring service for Covid-19 is a safe way to provide specialist care at home and can reduce hospital readmissions whilst improving patient experience.","PeriodicalId":319670,"journal":{"name":"Virtual monitoring in COVID-19","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132309017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the first wave of the Covid 19 pandemic, CRT piloted a service to support and monitor patients hospitalised with covid 19 pneumonia on discharge. Patients were provided with telehealth equipment for remote physiological monitoring, and were called daily by a member of the team. Results 157 patients (87 male, mean age 59.7, range 21–88) were supported by the CRT covid discharge service between May 2020 and May 2021. 11 (7%) were readmitted, 4 withdrew and 1 died at home. 141 completed 10–14 days of support. Mean hospital stay was 13.7 days (range 11–112). 8 were current smokers, 52 were ex smokers and 87 had never smoked. Mean BMI was 31.4 (range 18.5–54.5). Chair based exercises were introduced early and 141 were offered pulmonary rehabilitation, of whom 135 (95.7%) agreed to a referral; only 6 declined. Feedback from all patients supported by CRT was positive. We noted that anxiety levels improved subjectively during the period of CRT support so introduced GAD7 to further assess this. Although 28 patients achieved the minimal clinically significant difference, this was not seen consistently across the group. Conclusions Supported discharge after hospitalisation with covid pneumonia is safe and well-liked by patients. Readmissions were rare and pulmonary rehabilitation uptake was high. There may be some benefit in term of anxiety management, but numbers were too low for this to be proven.","PeriodicalId":319670,"journal":{"name":"Virtual monitoring in COVID-19","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115804896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In March 2020 we established one of the first virtual wards with the aim of supporting patients with a continuing oxygen requirement safely at home during their COVID-19 illness.MethodsThe virtual ward was delivered by the integrated care ImpACT+ service. This multi-disciplinary service comprises respiratory consultants, respiratory specialist nurses, physiotherapists, occupational therapists and fitness instructors. Our local criteria for on-boarding included: 10 days post onset of symptoms, oxygen requirement 4L or less and the ability to manage with home monitoring equipment. A mix of telephone and home contacts were offered and daily consultant MDTs undertaken. Therapy team members were up-skilled to support oxygen assessments and weaning regimes to maximise service capacity. A direct electronic referral icon was created on the hospital whiteboard system accompanied by a nurse-led telephone referral service. The scheme was advertised through posters and in-reach work into COVID-19 areas.Results107 patients were managed on our virtual ward since March 2020. This included 99 COVID-19 patients and 8 with other acute respiratory exacerbations. The mean continuous oxygen prescription on discharge was 1.5 L (range 0.5–4L) and for ambulatory purposes 2.4L (1–6L). 55 patients with COVID-19 were discharged on anticoagulation, 33 on steroids and 21 on antibiotics. 8 30-day readmissions, 3 deaths (2 expected). The total number of bed days on the virtual ward was 2010 (mean 21 days) and in total the activity that service delivered included 904 telephone calls and 274 home visits. Service feedback demonstrated a high level of satisfaction with patients commenting that they valued being at home with support during their recovery.ConclusionsThis service has shown a supported discharge Covid-19 oxygen weaning service is a valuable initiative to relieve pressures on the acute hospital service and provide high quality care to facilitate early discharge from hospital. This virtual ward highlighted the value of having an integrated respiratory team and extension of this model to other respiratory conditions should be possible with considered adaptions.","PeriodicalId":319670,"journal":{"name":"Virtual monitoring in COVID-19","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121417581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
