Aims
Transmission of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has led to a global pandemic. Many studies are underway to ascertain the mental health impact of this seismic event, however no study has investigated its effect on psychosis incidence. We hypothesise that the overall crude incidence rates of first episode psychosis (FEP) will be higher during the pandemic when comparing the same area of South London in defined pre-pandemic and pandemic time periods.
MethodsClinical records for all patients aged 18 to 64 years presenting to early intervention in psychosis services in the London boroughs of Southwark and Lambeth between July 1st 2019 to December 31st 2019 (pre-pandemic period) and July 1st 2020 to December 31st 2020 (pandemic period) were extracted from the Clinical Record Interactive Search (CRiS), an online database containing anonymised patient records. All patients were manually screened using the Screening Schedule for Psychosis to confirm FEP, with 104/235 cases meeting criteria for FEP in the pre-pandemic period compared with 158/376 in the pandemic period. Crude, age-standardised, and sex-standardised incidence rates and ratios were calculated for interpretation.
ResultsThe crude incidence rate of FEP was significantly higher in the pandemic period (68.3, 95% CI:[57.6 ; 78.9]) than the pre-pandemic period (44.9, 95% CI:[36.3 ; 53.6]). The crude incidence ratio was 1.52 (95% CI:[1.28 ; 1.77]), indicating that the overall crude incidence of FEP in the pandemic period was significantly higher (52%) than in the pre-pandemic period. The directionality and statistical significance of this ratio was unperturbed by standardisation for age (SIR = 1.45, 95% CI[1.23 ; 1.70]) and sex (SIR = 1.56, 95% CI[1.33 ; 1.83]).
ConclusionOur results suggest that the COVID-19 pandemic has had a significant impact on the incidence of FEP in the South London boroughs of Southwark and Lambeth. Further research is required to elucidate the factors contributing to this increase to inform targeted interventions and prevent deterioration in at-risk patients.

Aims
When using an assessment tool, brevity and validity are essential. Although brief depression inventories exist, they rely heavily on the inclusion of somatic symptoms. This can be problematic in advanced cancer populations; weight loss and sleep disturbance are for the most part ubiquitous in these patients and may not necessarily be indicative of depression.
The Brief Edinburgh Depression Scale (BEDS) is a 6-item shortened version of the Edinburgh Depression Scale which has been validated for use in patients with advanced cancer and is used internationally. The BEDS cut off threshold of 6/18 indicates that depression may be present. However, the BEDS currently provides no information regarding severity. The aim of this study is to establish severity thresholds for the BEDS by comparing it to another depression scale: the commonly used, rigorously validated, Patient Health Questionnaire (PHQ-9).
Method284 advanced cancer patients attending hospice day services in the North West of England completed both the PHQ-9 and the BEDS. Mean participant age was 66.7 (Standard Deviation = 13.2) and the sample contained both males (n = 102, 36%) and females (n = 182, 64%). BEDS severity thresholds with the highest Sensitivity (Sn) and Specificity (Sp) were selected based on their ability to predict PHQ-9 categories.
ResultA BEDS score of 4 to 6 was selected to indicate ‘mild depression’ (Sn = 81.7, Sp = 65); 7 to 8 ‘moderate depression’ (Sn = 74.8, Sp = 78.7); 9 to 11 ‘moderately severe depression’ (Sn = 82, Sp = 82.9) and 12 or more ‘severe depression’ (Sn = 63.2, Sp = 92.8). A linearly weighted kappa (with s weighting) showed a moderate level of agreement (0.47, 95% Confidence Interval: 0.40-0.54).
ConclusionThe BEDS is a simple and brief tool used to screen for depression in advanced cancer patients. It is administered throughout the UK and multiple translation studies have enabled its global a (including in resource poor countries). The severity thresholds calculated here are derived from a large sample of patients with advanced cancer attending hospice services and demonstrate acceptable sensitivity and specificity in relation to the PHQ-9, a thoroughly validated reference standard. We conclude that the generated BEDS thresholds support use of the BEDS in determining the presence and severity of depression in advanced cancer populations.
