Dedicated team to ambulatory care for patients with COVID-19 requiring oxygen: Low rate of hospital readmission

Transition of care interventions to manage severe COVID-19 in the ambulatory setting: a systematic review

BACKGROUND

Severe COVID-19, with the need in supplemental oxygen and hospitalization, leads to major burden on patients and healthcare systems. As a result, safe and effective ambulatory treatment strategies for severe COVID-19 are of urgent need. In this systematic review, we aimed to evaluate interventions to transition care to the ambulatory setting for patients with active severe COVID-19 that required supplemental oxygen.

METHODS

We searched Medline, Scopus, Web of Science, and DOAJ databases to identify articles with original data published until the 1st of April 2023. Characteristics and outcomes of interventions to transition care to home management were reviewed. Given the heterogeneous settings and outcomes studied, a meta-analysis was not performed.

RESULTS

Of the 235 studies identified, 11 observational studies, with 2645 patients, were included. The interventions were initiated from the emergency department, observation units or inpatient units, and included continuous home telemonitoring (n = 8), mobile applications (n = 2), and patient-initiated medical contact (n = 3). Included patients had an overall short length of hospital stay, high readmission rates, and positive patients' feedback. There was a lack of prospective controlled data and cost-effectiveness analyses.

CONCLUSION

Our findings highlight the potential in treating severe COVID-19 at the ambulatory setting and the lack of high-quality data in this field. Dedicated medical teams, adjusted monitoring methods, improving clinical trajectory, and correct inclusion settings are needed for safe and effective transition of care.

Antibiotic Consumption 2017-2022 in 30 Private Hospitals in France: Impact of Antimicrobial Stewardship Tools and COVID-19 Pandemic

Our aim was to determine the impact of antimicrobial stewardship tools (ASTs) and the COVID-19 pandemic on antibiotic consumption (AC). We used the national software Consores® to determine AC in DDD/1000 days of hospitalization from 2017 to 2022 in voluntary private hospitals in France. The ASTs considered were: 1. internal guidelines; 2. the list of antibiotics with restricted access; 3. the presence of an antibiotic referent or 4. an ID specialist; and 5. proof of an annual meeting on antimicrobial resistance. Institutions with dedicated units for COVID-19 patients were specified. In 30 institutions, the total AC varied from (means) 390 to 405 DDD/1000 DH from 2017 to 2022. Fluoroquinolones and amoxicillin/clavulanate consumption decreased from 50 to 36 (p = 0.003) and from 112 to 77 (p = 0.025), respectively, but consumption of piperacillin/tazobactam increased from 9 to 21 (p < 0.001). Over the study period, 10 institutions with ≤2 AST had lower AC compared to 20 institutions with ≥3 AST (p < 0.01). COVID-19 units opened in 10 institutions were associated with a trend toward higher macrolide consumption from 15 to 25 from 2017 to 2020 (p = 0.065) and with an acceleration of piperacillin/tazobactam consumption from 2020 to 2022 (p ≤ 0.003). Antibiotic consumption in 30 private hospitals in France was inversely related to the number of AST. The COVID-19 pandemic was associated with limited impact on AC, but special attention should be paid to piperacillin/tazobactam consumption.

Home oxygen therapy from the emergency department for COVID-19 an observational study

STUDY OBJECTIVE

During the COVID-19 pandemic, prescribing supplemental oxygen was a common reason for hospitalization of patients. We evaluated outcomes of COVID-19 patients discharged from the Emergency Department (ED) with home oxygen as part of a program to decrease hospital admissions.

METHODS

We retrospectively observed COVID-19 patients with an ED visit resulting in direct discharge or observation from April 2020 to January 2022 at 14 hospitals in a single healthcare system. The cohort included those discharged with new oxygen supplementation, a pulse oximeter, and return instructions. Our primary outcome was subsequent hospitalization or death outside the hospital within 30 days of ED or observation discharge.

RESULTS

Among 28,960 patients visiting the ED for COVID-19, providers admitted 11,508 (39.7%) to the hospital, placed 907 (3.1%) in observation status, and discharged 16,545 (57.1%) to home. A total of 614 COVID-19 patients (535 discharge to home and 97 observation unit) went home on new oxygen therapy. We observed the primary outcome in 151 (24.6%, CI 21.3-28.1%) patients. There were 148 (24.1%) patients subsequently hospitalized and 3 (0.5%) patients who died outside the hospital. The subsequent hospitalized mortality rate was 29.7% with 44 of the 148 patients admitted to the hospital dying. Mortality all cause at 30 days in the entire cohort was 7.7%.

CONCLUSIONS

Most patients discharged to home with new oxygen for COVID-19 safely avoid later hospitalization and few patients die within 30 days. This suggests the feasibility of the approach and offers support for ongoing research and implementation efforts.

Starting Home Telemonitoring and Oxygen Therapy Directly after Emergency Department Assessment Appears to Be Safe in COVID-19 Patients

BACKGROUND

Since data on the safety and effectiveness of home telemonitoring and oxygen therapy started directly after Emergency Department (ED) assessment in COVID-19 patients are sparse but could have many advantages, we evaluated these parameters in this study.

METHODS

All COVID-19 patients ≥18 years eligible for receiving home telemonitoring (November 2020-February 2022, Albert Schweitzer hospital, the Netherlands) were included: patients started directly after ED assessment (ED group) or after hospital admission (admission group). Safety (number of ED reassessments and hospital readmissions) and effectiveness (number of phone calls, duration of oxygen usage and home telemonitoring) were described in both groups.

RESULTS

278 patients were included (n = 65 ED group, n = 213 admission group). ED group: 23.8% (n = 15) was reassessed, 15.9% (n = 10) was admitted and 7.7% (n = 5) ICU admitted. Admission group: 15.8% (n = 37) was reassessed, 6.5% (n = 14) was readmitted and 2.4% (n = 5) ICU (re)admitted. Ten patients died, of whom 7 due to COVID-19 (1 in ED group; 6 in the admission group). ED group: median duration of oxygen therapy was 9 (IQR 7-13) days; the total duration of home telemonitoring was 14 (IQR 9-18) days. Admission group: duration of oxygen therapy was 10 (IQR 6-16) days; total duration of home telemonitoring was 14 (IQR 10-20) days.

CONCLUSION

it appears to be safe to start home telemonitoring and oxygen therapy directly after ED assessment.
