Where are our patients? Retrospective cohort study of acute medical unit admissions during and prior to the COVID-19 pandemic

Emergencies in the COVID-19 Era: Less Attendances, More Admissions

Introduction

Healthcare systems suffered a significant hit by the COVID-19 pandemic since the spring of 2020, and a need for major reorganization emerged. Along with the constant increase in COVID-19 cases, a significant drop in emergency attendances for non-COVID-19-related conditions was noted worldwide. We decided to document attendances in our hospital's emergency department during the first lockdown period in order to monitor this trend, compare it to data from other countries, and start monitoring the effects of this reduction in the years to come.

Materials and methods

Emergency department attendances at AHEPA University Hospital, Thessaloniki, Greece, from March 10, 2020, to May 31, 2020, were documented and compared to the corresponding period in 2019. The data collected included the number of patients per specialty, severity upon admission, as well as the need for admission.

Results

We found a 58% reduction in emergency department attendance during the studied period compared to the corresponding period in 2019 (p<0.0001). The reduction was more noticeable in ears, nose, throat (ENT), and ophthalmology attendances (75.7% and 78.1% reductions, respectively, p<0.001), but other specialties, such as cardiology and general surgery, were also significantly affected (60% and 63% reductions, respectively, p<0.001). However, the percentage of attendances that required admission increased significantly by 25-33% (p<0.001) during the lockdown, reflecting the higher severity of cases reaching the hospital.

Conclusion

Despite the obvious reduction in attendances during the COVID-19 pandemic, patients still suffer from serious conditions that require hospital admission. Therefore, hospitals need to be supported to also care for these patients. The long-term effects of avoiding hospital attendance need to be closely monitored.

Acute medical units during the first wave of the COVID-19 pandemic: a cross-national exploratory study of impact and responses

BACKGROUND

The COVID-19 pandemic represents one of the greatest ever challenges for healthcare. In the UK and beyond, acute medical units (AMUs) are the first point of assessment and care for the majority of medical inpatients. By their design and systems, they inevitably played an important role in the COVID-19 response but to date little has been published on how the COVID-19 pandemic has affected how AMUs have reorganised their resources, processes and structure.

METHODS

This retrospective study in August 2020 of 10 AMUs across Europe and Australasia used a standardised questionnaire to investigate existing practice and structure of AMUs, the national context of local hospital experience, changes to practice during the COVID-19 pandemic and views regarding future practice.

RESULTS

Changes to AMU structure, process and organisation are described in two contexts: preventing and controlling the spread of COVID-19 and adding value to the patient's acute care journey in the local context. We describe novel practices that have arisen and highlight areas of concern.

CONCLUSIONS

The AMUs were able to adapt to meet the demands of acute care delivery during the first wave of the COVID-19 pandemic. Operational planning and prioritisation of resources must be optimised to ensure sustainability of these services for future waves.

COVID-19 had no impact on emergency urological admissions at an Australian tertiary hospital

BACKGROUNDS

The COVID-19 pandemic is an unprecedented threat to health and healthcare systems. There is no published data on the impact on urological presentations in Australia.

METHODS

A retrospective analysis of all admissions under the urology service at Liverpool Hospital, Australia from February 1st to April 30th for 2020 and the previous 5 years.

RESULTS

There was a total of 397 admissions in 2020 and 438 in 2019. The mean age, proportion of male, and mean length of stay were similar. In 2020, there were 229 emergency admissions. Over the same period during the previous 5 years, there were between 195 and 218 emergency admissions. In 2019, there were 220 planned admissions and 168 in 2020. Between 2019 and 2020, there was no significant difference in the proportion of patients with admission longer than 10 days (P = 0.602), requiring intensive care unit admission (P = 0.708) or inpatient operative management (P = 0.171). Among the emergency admissions, the mean Charlson Comorbidity Index was significantly lower in 2020 compared to 2019 (P = 0.009).

CONCLUSIONS

Despite the pervasive fear of the COVID-19 pandemic and multiple, substantial alterations to hospital systems, structures and elective operating restrictions, no significant difference in numbers or acuity of emergency admissions were observed. Due to limitations in elective operating, there was an expected reduction in planned admissions. Our findings are in contrast to multiple recent studies and may be the result of our patient demographic where health-seeking behaviours appear to have not been significantly influenced by the pandemic.

Threat of COVID-19 impacting on a quaternary healthcare service: a retrospective cohort study of administrative data

OBJECTIVES

The threat of a pandemic, over and above the disease itself, may have significant and broad effects on a healthcare system. We aimed to describe the impact of the SARS-CoV-2 pandemic (during a relatively low transmission period) and associated societal restrictions on presentations, admissions and outpatient visits.

DESIGN

We compared hospital activity in 2020 with the preceding 5 years, 2015-2019, using a retrospective cohort study design.

SETTING

Quaternary hospital in Melbourne, Australia.

PARTICIPANTS

Emergency department presentations, hospital admissions and outpatient visits from 1 January 2015 to 30 June 2020, n=896 934 episodes of care.

INTERVENTION

In Australia, the initial peak COVID-19 phase was March-April.

PRIMARY AND SECONDARY OUTCOME MEASURES

Separate linear regression models were fitted to estimate the impact of the pandemic on the number, type and severity of emergency presentations, hospital admissions and outpatient visits.

RESULTS

During the peak COVID-19 phase (March and April 2020), there were marked reductions in emergency presentations (10 389 observed vs 14 678 expected; 29% reduction; p<0.05) and hospital admissions (5972 observed vs 8368 expected; 28% reduction; p<0.05). Stroke (114 observed vs 177 expected; 35% reduction; p<0.05) and trauma (1336 observed vs 1764 expected; 24% reduction; p<0.05) presentations decreased; acute myocardial infarctions were unchanged. There was an increase in the proportion of hospital admissions requiring intensive care (7.0% observed vs 6.0% expected; p<0.05) or resulting in death (2.2% observed vs 1.5% expected; p<0.05). Outpatient attendances remained similar (30 267 observed vs 31 980 expected; 5% reduction; not significant) but telephone/telehealth consultations increased from 2.5% to 45% (p<0.05) of total consultations.

CONCLUSIONS

Although case numbers of COVID-19 were relatively low in Australia during the first 6 months of 2020, the impact on hospital activity was profound.

Differential trends of admissions in accident and emergency departments during the COVID-19 pandemic in Germany

Background

Recent studies have shown a decrease of admissions to accident and emergency (A&E) departments after the local outbreaks of COVID-19. However, differential trends of admission counts, for example according to diagnosis, are less well understood. This information is crucial to inform targeted intervention. Therefore, we aimed to compare admission counts in German A&E departments before and after 12th march in 2020 with 2019 according to demographic factors and diagnosis groups.

Methods

Routine data of all admissions between 02.12.2019–30.06.2020 and 01.12.2018–30.06.2019 was available from six hospitals in five cities from north-western, eastern, south-eastern, and south-western Germany. We defined 10 diagnosis groups using ICD-10 codes: mental disorders due to use of alcohol (MDA), acute myocardial infarction (AMI), stroke or transient ischemic attack (TIA), heart failure, pneumonia, chronic obstructive pulmonary disease (COPD), cholelithiasis or cholecystitis, back pain, fractures of the forearm, and fractures of the femur. We calculated rate ratios comparing different periods in 12.03.2020–30.06.2020 with 12.03.2019–30.06.2019.

Results

Forty-one thousand three hundred fifty-three cases were admitted between 12.03.2020–30.06.2020 and 51,030 cases between 12.03.2019–30.06.2019. Admission counts prior to 12.03. were equal in 2020 and 2019. In the period after 12.03., the decrease of admissions in 2020 compared to 2019 was largest between 26.03. and 08.04. (− 30%, 95% CI − 33% to − 27%). When analysing the entire period 12.03.-30.06., the decrease of admissions was heterogeneous among hospitals, and larger among people aged 0–17 years compared to older age groups. In the first 8 weeks after 12.03., admission counts of all diagnoses except femur fractures and pneumonia declined. Admissions with pneumonia increased in this early period. Between 07.05. and 30.6.2020, we noted that admissions with AMI (+ 13%, 95% CI − 3% to + 32%) and cholelithiasis or cholecystitis (+ 20%, 95% CI + 1% to + 44%) were higher than in 2019.

Conclusions

Our results suggest differential trends of admission counts according to age, location, and diagnosis. An initial decrease of admissions with MDA, AMI, stroke or TIA, heart failure, COPD, cholelithiasis or cholecystitis, and back pain imply delays of emergency care in Germany. Finally, our study suggests a delayed increase of admissions with AMI and cholelithiasis or cholecystitis.
