The Impact

ObjectivesThe 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.DesignWe compared hospital activity in 2020 with the preceding 5 years, 2015–2019, using a retrospective cohort study design.SettingQuaternary hospital in Melbourne, Australia.ParticipantsEmergency department presentations, hospital admissions and outpatient visits from 1 January 2015 to 30 June 2020, n=896 934 episodes of care.InterventionIn Australia, the initial peak COVID-19 phase was March–April.Primary and secondary outcome measuresSeparate 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.ResultsDuring 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.ConclusionsAlthough case numbers of COVID-19 were relatively low in Australia during the first 6 months of 2020, the impact on hospital activity was profound.

Objective: To compare emergency department (ED) presentations and hospital admissions for urgent early pregnancy conditions in Victoria before and after the onset of COVID-19 lockdown on 31 March 2020. Design: Population-based retrospective cohort study Setting: Australian state of Victoria Population: Pregnant women presenting to emergency departments or admitted to hospital Methods: We obtained state-wide hospital separation data from the Victorian Emergency Minimum Dataset and the Victorian Admitted Episodes Dataset from January 1, 2018, to October 31, 2020. A linear prediction model based on the pre-COVID period was used to identify the impact of COVID restrictions. Main outcome measures: Monthly ED presentations for miscarriage and ectopic pregnancy, hospital admissions for termination of pregnancy, with subgroup analysis by region, socioeconomic status, disease acuity, hospital type. Results: There was an overall decline in monthly ED presentations and hospital admissions for early pregnancy conditions in metropolitan areas where lockdown restrictions were most stringent. Monthly ED presentations for miscarriage during the COVID period were consistently below predicted, with the nadir in April 2020 (790 observed vs 985 predicted, 95% CI 835-1135). Monthly admissions for termination of pregnancy were also below predicted throughout lockdown, with the nadir in August 2020 (893 observed vs 1116 predicted, 95% CI 905-1326). There was no increase in ED presentations for complications following abortion, ectopic or molar pregnancy during the COVID period. Conclusions: Fewer women in metropolitan Victoria utilized hospital-based care for early pregnancy conditions during the first seven months of the pandemic, without any observable increase in maternal morbidity.

ObjectivesPoor social conditions are strong determinants of poor health but positive health and healthcare changes caused by social interventions are difficult to demonstrate. In 2006, in Trieste (Italy), a social intervention known as ‘Habitat Microaree’ (HM) project was implemented in eight deprived neighbourhoods. In 2016, an observational study was launched to assess the impact of the HM project on healthcare.DesignRetrospective cohort study.SettingThe eight geographically defined neighbourhoods of Trieste involved in the 2006 HM project, accounting for a total of 11 380 residents.ParticipantsParticipants were all residents in the intervention areas. By means of a propensity score based on deprivation index, age, sex, Charlson index and drug utilisation, a non-participating, comparison group was defined.InterventionThe community-based intervention consisted of facilitating access to social services and outpatient healthcare facilities, coordinating intersectoral public services and specifically planning hospital discharge. These services were not provided in other areas of the city.Outcome measuresHospital admissions and emergency department access.ResultsWe followed 16 256 subjects between 2008 and 2015. Living in microareas was associated with an HR for first hospital admission, for all causes, of 0.95 (95% CI 0.91 to 0.99); while the HR for urgent admissions in females was 0.92 (95% CI 0.85 to 1.00). The HR for psychiatric disorders, in females, was 0.39 (95%CI 0.18 to 0.82); in particular, the HR for psychosis was 0.15 (95% CI 0.05 to 0.51). The HR for acute respiratory diseases in females was 0.44 (95% CI 0.21 to 0.95). In males, the HR for genitourinary diseases and heart diseases were 0.65 (95% CI 0.42 to 1.01) and 0.72 (95% CI 0.54 to 0.97), respectively. Concerning urgent multiple admissions, the OR for fractures in females was 0.75 (95% CI 0.58 to 0.97).ConclusionIn the study period, the effects on healthcare appear evident, especially in females.

2016 Kumamoto Earthquakes

Background and objectivesThe Kumamoto earthquakes struck Kumamoto prefecture, in the southwest part of Japan in April 2016. Physical and mental disorders presenting to hospital increased after the 2016 Kumamoto earthquakes. Impaired access to primary care due to the earthquakes may have contributed to this increase. However, it is not known whether the 2016 Kumamoto earthquakes affected access to primary care. The objective of the present study was to investigate the impact of the 2016 Kumamoto earthquakes on short-term health conditions by analysing ambulatory care sensitive conditions (ACSCs), using administrative data from Kumamoto prefecture.DesignA retrospective cohort study.SettingResidents enrolled in National Health Insurance or Late Elders’ Health Insurance from Kumamoto prefecture, Japan.ParticipantsAll hospital admissions due to ACSCs between 15 March and 16 May in each year from 2013 to 2016.Outcome measuresACSCs are defined as conditions for which appropriate primary care interventions could prevent admission to the hospital.ResultsWe identified a total of 7921, 18 763 and 85 436 admissions for vaccine, acute and chronic preventable ACSCs, respectively, during the study period. Admissions within 7 days after the 2016 Kumamoto earthquakes increased to 32.6% (10.2, 59.5), 44.1% (27.0, 63.5) and 27.7% (20.2, 35.6) for vaccine-preventable, acute and chronic ACSCs, respectively. However, admissions for ACSCs did not change significantly 30 days after the earthquakes.ConclusionThe 2016 Kumamoto earthquakes were associated with increased hospital admissions for ACSCs. The impact of the earthquakes on admissions for ACSCs did not persist for more than 7 days.

ObjectiveTo provide a comprehensive description of demographic, clinical and radiographic characteristics; treatment and case outcomes; and risk factors associated with in-hospital death of patients hospitalised with COVID-19 in Brazil.DesignRetrospective cohort study of hospitalised patients diagnosed with COVID-19.SettingData from all hospitals across Brazil.Participants522 167 hospitalised patients in Brazil by 14 December 2020 with severe acute respiratory illness, and a confirmed diagnosis for COVID-19.Primary and secondary outcome measuresPrevalence of symptoms and comorbidities was compared by clinical outcomes and intensive care unit (ICU) admission status. Survival was assessed using Kaplan Meier survival estimates. Risk factors associated with in-hospital death were evaluated with multivariable Cox proportional hazards regression.ResultsOf the 522 167 patients included in this study, 56.7% were discharged, 0.002% died of other causes, 30.7% died of causes associated with COVID-19 and 10.2% remained hospitalised. The median age of patients was 61 years (IQR, 47–73), and of non-survivors 71 years (IQR, 60–80); 292 570 patients (56.0%) were men. At least one comorbidity was present in 64.5% of patients and in 76.8% of non-survivors. From illness onset, the median times to hospital and ICU admission were 6 days (IQR, 3–9) and 7 days (IQR, 3–10), respectively; 15 days (IQR, 9–24) to death and 15 days (IQR, 11–20) to hospital discharge. Risk factors for in-hospital death included old age, Black/Brown ethnoracial self-classification, ICU admission, being male, living in the North and Northeast regions and various comorbidities. Age had the highest HRs of 5.51 (95% CI: 4.91 to 6.18) for patients≥80, compared with those ≤20.ConclusionsCharacteristics of patients and risk factors for in-hospital mortality highlight inequities of COVID-19 outcomes in Brazil. As the pandemic continues to unfold, targeted policies that address those inequities are needed to mitigate the unequal burden of COVID-19.

ObjectiveFor eight chronic diseases, evaluate the association of specialist palliative care (PC) exposure and timing with hospital-based acute care in the last 30 days of life.DesignRetrospective cohort study using administrative data.SettingAlberta, Canada between 2007 and 2016.Participants47 169 adults deceased from: (1) cancer, (2) heart disease, (3) dementia, (4) stroke, (5) chronic lower respiratory disease (chronic obstructive pulmonary disease (COPD)), (6) liver disease, (7) neurodegenerative disease and (8) renovascular disease.Main outcome measuresThe proportion of decedents who experienced high hospital-based acute care in the last 30 days of life, indicated by ≥two emergency department (ED) visit, ≥two hospital admissions,≥14 days of hospitalisation, any intensive care unit (ICU) admission, or death in hospital. Relative risk (RR) and risk difference (RD) of hospital-based acute care given early specialist PC exposure (≥90 days before death), adjusted for patient characteristics.ResultsIn an analysis of all decedents, early specialist PC exposure was associated with a 32% reduction in risk of any hospital-based acute care as compared with those with no PC exposure (RR 0.69, 95% CI 0.66 to 0.71; RD 0.16, 95% CI 0.15 to 0.17). The association was strongest in cancer-specific analyses (RR 0.53, 95% CI 0.50 to 0.55; RD 0.31, 95% CI 0.29 to 0.33) and renal disease-specific analyses (RR 0.60, 95% CI 0.43 to 0.84; RD 0.22, 95% CI 0.11 to 0.34), but a~25% risk reduction was observed for each of heart disease, COPD, neurodegenerative diseases and stroke. Early specialist PC exposure was associated with reducing risk of four out of five individual indicators of high hospital-based acute care in the last 30 days of life, including ≥two ED visit,≥two hospital admission, any ICU admission and death in hospital.ConclusionsEarly specialist PC exposure reduced the risk of hospital-based acute care in the last 30 days of life for all chronic disease groups except dementia.

ObjectivesMany researchers have expected pioglitazone to serve as an effective neuroprotective agent against Parkinson’s disease (PD). Therefore, we conducted this cohort study to investigate the association between pioglitazone use and PD by using a large Asian population-based dataset in Taiwan.DesignRetrospective cohort study.SettingTaiwan.Participants7906 patients with diabetes who had received pioglitazone were defined as the study cohort, and 7906 matched patients with diabetes who had not received pioglitazone were defined as the comparison cohort.Primary and secondary outcome measuresWe tracked each patient individually over a 5-year follow-up period to identify those diagnosed as having PD during this period. We performed Cox proportional hazard regression analyses to evaluate the HRs for PD between the study and comparison cohorts.ResultsThe findings indicated that among the sampled patients, PD occurred in 257 (1.63%): 119 (1.51%) pioglitazone users and 138 (1.75%) non-users. The adjusted HR for PD within the follow-up period was 0.90 (95% CI: 0.68 to 1.18) in the patients who had received pioglitazone compared with the matched patients who had not received pioglitazone. Moreover, this study revealed that pioglitazone use was not associated with PD incidence in men (HR: 1.06, 95% CI: 0.71 to 1.59) or women (HR: 0.84, 95% CI: 0.61 to 1.15).ConclusionsThis study did not find the relationship between pioglitazone use and PD incidence, regardless of sex, among an Asian population of patients with diabetes.
