Consequences of delaying non-urgent surgeries during COVID-19: a population-based retrospective cohort study in Alberta, Canada

Objectives
To ensure sufficient resources to care for patients with COVID-19, healthcare systems delayed non-urgent surgeries to free capacity. This study explores the consequences of delaying non-urgent surgery on surgical care and healthcare resource use.

Design
This is a population-based retrospective cohort study.

Setting
This study took place in Alberta, Canada, from December 2018 to December 2021.

Participants
Adult patients scheduled for surgery in Alberta during the study period were included.

Primary and secondary outcomes measures
The proportion of surgeries completed and surgery wait time were the primary outcomes. The secondary outcomes were healthcare resource use (hospital length of stay, emergency room visits and physician visits). The association between the primary outcomes and patient and surgery-related variables was explored using regression.

Results
There were 202 470 unique patients with 259 677 scheduled surgeries included. Fewer surgeries were completed throughout the pandemic compared with before; in the fourth wave, there was a decrease from 79% pre-COVID-19 to 67%. There was a decrease in wait time for those who had surgery completed during COVID-19 (from 105 to 69 days). Having surgery completed and the wait for surgery were associated with the geographical zone, COVID-19 wave, and the surgery type and priority. There was a decrease in all measures of healthcare resource use and an increase in hospital and all-cause mortality during COVID-19 compared with before COVID-19.

Conclusions
The change in the proportion of scheduled surgeries completed and the wait time for completed surgery was modest and associated with COVID-19 wave and surgery-related variables, which was aligned with policies enacted during COVID-19 for surgery. The decrease in healthcare resource use suggests the effects of the COVID-19 pandemic may be delayed and may result in many patients presenting with advanced disease requiring surgical care.

Associations between pre-existing comorbidities and in-hospital cardiovascular events and mortality among COVID-19 patients in Bangladesh: a secondary analysis of a prospective cohort study

Objective
To identify the associations of in-hospital cardiovascular events and mortality with pre-existing comorbidities and cardiovascular disease (CVD) risk factors among COVID-19 patients in Bangladesh without vaccine availability.

Design
A secondary analysis of a prospective multicountry study.

Setting
Three COVID-19-designated hospitals in Bangladesh.

Participants
Adult patients aged ≥18 years with PCR-positive COVID-19 admitted between 10 October 2020 and 31 July 2021 at participating hospitals.

Outcome measures
In-hospital cardiovascular events and mortality.

Main exposures
Pre-existing comorbidities and cardiovascular risk factors.

Results
In 897 COVID-19 patients, 18.7% developed cardiovascular events and 12.6% died. After adjusting for clinical information and treatment, patients with two comorbidities (excluding CVD risk factors) were significantly associated with cardiovascular events (adjusted (adj.) OR 2.47, 95% CI 1.24 to 4.90). Patients with a higher heart rate at admission (adj. OR 1.03, 95% CI 1.01 to 1.04) and those who were receiving intravenous fluids (adj. OR 2.13, 95% CI 1.23 to 3.70) or antibiotics (adj. OR 4.54, 95% CI 1.47 to 14.01) had significantly higher odds of cardiovascular events. The odds of cardiovascular events were lower in those receiving antiviral medications (adj. OR 0.31, 95% CI 0.18 to 0.53). There were no interactions between comorbidities and other covariates in the models. Comorbidities and cardiovascular risk factors were not significantly associated with 30-day mortality in the Cox regression models after adjusting with clinical information and treatment. The mortality within 30 days of admission was significantly higher in patients receiving corticosteroids (adj. HR 2.82, 95% CI 1.48 to 5.38) and lower in those receiving antiviral treatment (adj. HR 0.53, 95% CI 0.34 to 0.81). Those having cardiovascular events significantly increased mortality hazard.

Conclusions
Clinical factors and treatment affected in-hospital cardiovascular events, which subsequently increased the risk of mortality within 30 days for COVID-19 patients. COVID-19 patients regardless of CVD risk factors and comorbidities require close monitoring for cardiovascular events.

Physiotherapy interventions in post- and long-COVID-19: a scoping review protocol

Introduction
Post- or long-COVID-19 conditions manifest with a spectrum of symptoms reminiscent of pulmonary, musculoskeletal, psychological and neurological disorders. Individuals with post- or long-COVID-19 syndrome often present with myalgia, pulmonary problems and fatigue, which significantly impact their daily functioning. Physiotherapy interventions are an accepted medical remedy for these symptoms. This scoping review aims to outline the evidence of physiotherapy interventions documented in the scientific literature, specifically focusing on hands-on therapy.

Methods and analysis
This scoping review conforms to the methodological framework established by the Joanna Briggs Institute (JBI). The procedure for drafting a scoping review involves several steps, starting with defining the research question and the inclusion and exclusion criteria. Eligible studies are those analysing physiotherapy treatment parameters for direct patient interaction in post- and long-COVID-19 patients. Telemedicine and entirely home-based workouts will be excluded aligning with the context of outpatient physiotherapy in Germany. The literature search will be conducted in PubMed, EBSCO research, Scopus, Web of Science, Embase, PEDRO, Cochrane and WISO databases by two independent researchers. Screening, data extraction and a critical appraisal will be performed by these researchers using assessment tools provided by the JBI. Extracted data will encompass demographic characteristics, definitions of post- or long-COVID-19 conditions, descriptions of interventions, their treatment parameters and treatment outcome. Subsequently, findings will be disseminated through a scoping review article or conference presentation.

Ethics and dissemination
Given that this review does not involve human participants, ethical committee approval is deemed unnecessary. The results will be published in peer-reviewed journals and presented at academic and physiotherapeutic conferences.
