To compare primary care for depression among patients detected in the first 21 months of the SARS-CoV-2 pandemic to patients detected pre-pandemic, and examine whether depression care was associated with patient characteristics.
Retrospective pre–post study using de-identified data from electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN).
Primary care clinics enrolled in CPCSSN from 1 January 2018 to 31 December 2021.
Patients with a valid CPCSSN case definition of depression detected between 01 January 2018 and 31 December 2021 were included in the cohort and categorised by detection date (pre-pandemic or during Canadian pandemic waves).
Primary care encounters, psychotropic prescriptions and selective serotonin reuptake inhibitor (SSRI) prescriptions were observed at 3 and 12 months post-detection. Multivariable regression evaluated associations between patients’ depression detection timing and depression care, adjusting for age, sex, rurality, neighbourhood deprivation quintile, province, number of observable comorbidities and pre-detection psychotropic use.
91 453 patients with depression were identified, of whom 53% were detected pre-pandemic. Patients detected during the pandemic were younger and less comorbid than those detected pre-pandemic. Proportions of patients with any encounter, psychotropic prescriptions and SSRI prescriptions were higher for patients detected during every pandemic wave compared with patients detected pre-pandemic. The adjusted incidence rate ratios (aIRRs) of number of encounters (aIRR=1.15; 95% CI 1.13 to 1.17), psychotropics (aIRR=1.11, 95% CI 1.09 to 1.13) and SSRIs prescribed (aIRR=1.12; 95% CI 1.10 to 1.15) within 3 months of detection were higher among patients detected during the first pandemic wave compared with those detected pre-pandemic. Socio-demographic characteristics had weaker associations with outcomes compared with timing of detection. Results were similar within 12 months of detection.
Overall, primary care for depression was maintained during the pandemic despite challenging circumstances. Increases in paediatric encounter rates and increased prescribing in younger adults warrant further investigation to understand the factors driving these patterns.

To explore the abnormal experiences of time and space among transitional-age youth with major depressive disorder.
A descriptive phenomenological qualitative study.
The study was conducted at a psychiatric hospital in China. Purposive sampling was used to recruit transitional-age youth with major depressive disorder. Data were collected through semi-structured interviews and analysed using Colaizzi's method.
Seventeen participants were interviewed. The abnormal experiences of time and space among transitional-age youth with major depressive disorder were synthesised into five overarching themes: (1) Disturbance of Time Order; (2) Slackening of the Flow of Time; (3) Vital Inhibition; (4) Desynchronisation of Social Rhythms; and (5) Disturbance of Lived Space.
This study highlights that pervasive abnormalities in temporal and spatial experiences characterise transitional-age youth with major depressive disorder. These disturbances shape their sense of self, personal development, relationships and engagement with the world, underscoring the need for interventions that address these temporal and spatial disturbances within the context of developmental transition.
This study addresses a knowledge gap regarding the subjective experience of time and space among transitional-age youth with major depressive disorder. This study highlights that transitional-age youth with major depressive disorder experience desynchronisation across temporal, spatial, bodily and social domains. Moreover, the desynchronisation of social rhythms appears to be a unique and developmentally salient challenge for transitional-age youth with major depressive disorder. These insights expand phenomenological understandings of major depressive disorder and highlight the developmental vulnerabilities of major depressive disorder as it navigates this critical life phase.
Five participants were involved in reviewing and providing feedback on the interview content and results. Their contributions included enhancing the authenticity and credibility of the findings.
The study followed the Consolidated Criteria for Reporting Qualitative Research guidelines.
The management of severe traumatic brain injury (sTBI) in the intensive care unit (ICU) is focused on preventing secondary brain insults, by ensuring adequate cerebral perfusion, oxygenation and substrate delivery. Despite optimisation of intracranial pressure (ICP) and cerebral perfusion pressure (CPP) using evidence-based guidelines, brain tissue hypoxia can still occur and is strongly associated with adverse functional outcomes post sTBI.
The Brain Oxygen Neuromonitoring in Australia and New Zealand Assessment – Global Trial (BONANZA-GT) is an international, two-arm, open-label, parallel group, randomised controlled trial comparing sTBI management incorporating early brain tissue oxygen (PbtO2) monitoring and optimisation, with ICP/CPP-based management alone. A total of 860 adults admitted to participating institutions with non-penetrating sTBI and requiring insertion of an ICP monitor (as determined by the treating neurosurgeon) will be enrolled. The primary outcome is the proportion of patients with favourable neurological outcomes, as defined by a Glasgow Outcome Score-Extended (GOS-E) >4, at 6 months following injury. Key secondary outcomes include all-cause mortality at ICU discharge, hospital discharge, adverse events, as well as hospital and ICU length of stay and GOS-E at 12 months. The BONANZA-GT will determine whether a protocolised therapeutic strategy guided by continuous PbtO2 monitoring in addition to ICP/CPP targets results in improved neurological outcomes when compared with standard care using ICP/CPP-guided management alone.
Approval has been obtained from relevant ethics boards in every jurisdiction that is participating in the trial. Inclusion of adults who lack capacity for informed consent will be governed in accordance with the legal requirements of each participating site. Study findings will be presented at scientific meetings and disseminated via peer-review publications.
