The Western Australian experience of COVID-19 after the borders reopened: evaluation of public health modelling predictions.

BACKGROUND: Western Australia (WA) serves as a unique global case study on the impact of coronavirus disease 2019 (COVID-19) on an isolated, prepared and highly vaccinated population. This study builds upon the study performed by House et al. through an extended data set. AIM: To examine the impact of COVID-19 at the only quaternary hospital in WA following the border opening from 3 March to 17 July 2022. PARTICIPANTS: A total of 257 adults were admitted with COVID-19 under either respiratory or the intensive care unit (ICU). OUTCOMES: Admission numbers, disease severity, ICU admission, prevalence of COVID-19 deterioration risk factors, length of stay and mortality. RESULTS: A total of 257 patients were admitted with COVID-19, under respiratory (81.7%) and ICU (18.3%). COVID-19 was the primary reason for admission for 67.7%. Ten patients died during the study, with seven deaths attributed to COVID pneumonitis. COVID-19 severity was 37.4% mild, 37.0% moderate, 18.3% severe and 7.4% critical. Risk factors for requiring ICU included incomplete immunisation status (P = 0.011), chronic kidney disease (P = 0.008) and Aboriginal and Torres Strait Islander (ATSI) ethnicity. The WA Department of Health predicted that the number of hospitalisations and ICU cases were significantly higher than the actual number of cases. CONCLUSION: The number of hospitalisations and ICU COVID-19 cases were significantly less than predicted, likely due to high population vaccination rates prior to border opening. The main risk factors for COVID-19 severity were incomplete immunisation and ATSI ethnicity.

The unique COVID-19 experience in Western Australia: lessons learnt.

BACKGROUND: Western Australia (WA) was in a unique position to experience coronavirus disease 2019 (COVID-19) in a highly vaccinated and geographically isolated population. AIM: To describe the COVID-19 Omicron experience at the only quaternary hospital in WA following border opening from 3 March to 11 May 2022. PARTICIPANTS: A total of 158 adults with microbiologically confirmed COVID-19 were admitted to the respiratory or intensive care unit (ICU). OUTCOMES: Admission numbers, disease severity, prevalence of COVID-19 deterioration risk factors, immunisation status, severity of infection, immunosuppression and treatment regimen. RESULTS: One hundred fifty-eight COVID-19-positive patients were admitted to the respiratory ward (n = 123) and the ICU (n = 35) during the study period. COVID-19 infection was the primary admission reason in 32.9% of patients, 51.3% were male and the median age was 62 years. Aboriginal or Torres Strait Islanders (ATSI) were overrepresented (13.3%). Care was predominantly ward based (77.2%). Nearly half of the patients had mild COVID-19 (49.4%). Dexamethasone was the most common treatment provided to patients (58.2%). The median length of stay was 5.8 days (interquartile range, 5-15). Eight patients died during the study period (5.1%), with three of those deaths attributable to COVID-19. CONCLUSIONS: COVID-19 case numbers following WA state border opening were of lower care acuity and disease severity than predicted. Two-thirds of admissions were for other primary diagnoses, with incidental COVID detection. Hospital admissions were overrepresented by partially or unvaccinated patients and by ATSI Australians. An increase in social support along with general and geriatric medicine speciality input were required to treat hospitalised COVID-19 cases in the WA Omicron wave.

Student Exposure to Cancer Patients: an Analysis of Clinical Logbooks and Focus Groups in Clinical Year Medical Students.

Despite cancer being the leading cause of mortality, cancer education and patient exposure are lacking in many medical schools. The aim of this study was to evaluate the nature of cancer patient exposure, relative to the clinical setting for medical students on placement and to explore their experiences. Participants were asked to maintain a logbook of cancer patient encounters and were invited to attend a structured focus group upon completion of the academic year. Eleven students submitted logbooks (rr = 6.15%) and eight participated in the focus groups (4.47%). A total of 247 cancer patient encounters were recorded. Third-year students primarily saw cancer patients in surgery (18.62%) and general practice (8.50%), whilst final year students saw cancer patients most frequently in palliative care (35.22%) and ENT surgery (13.77%). Students highlighted that the quality of their interactions with cancer patients varied significantly between clinical settings. Outpatient clinics and surgical in-patients had the lowest level of interaction, with students having a predominantly observatory role. Repeated themes of uncertainty and awkwardness regarding history, examination and discussing death and dying were outcomes of the thematic analysis. Exposure to cancer patients remains highly variable and opportunistic. Students voiced concerns for preparedness to practice and many found it worrisome that they will likely examine a primary cancer when they have graduated, without having done so during their training. Our study suggests that a more structured approach to teaching and clinical exposure to cancer patients is required.
