Future efforts should be invested in prospective studies, including several years' post-discharge follow-up, to explore correlations with LOS and guide treatment decisions. PRACTITIONER MESSAGE: Inpatient treatment in specialist eating disorder units is associated with nutritional and psychological benefits in adults and adolescents. Treatment requiring legal detention or nasogastric feeding involves longer admission. Further research is needed to see whether benefits are lasting.

AimsTo establish if there were any significant changes in the number of referrals for psychiatric assessment or prescribing rates of psychotropic medication in the South Edinburgh tier 3 CAMHS team during the first year of the COVID-19 pandemic compared to the previous year. To explore factors that might be responsible for these changes.MethodsReferrals to the Psychiatric Assessment Clinic were analysed between the periods of 23rd March 2019 and 22nd March 2020 and 23rd March 2020 to 22nd March 2021. Using the unique numeric patient identifier, data from these referrals was gathered retrospectively by looking at clinical documentation on the healthcare information system used across NHS Lothian. Data were gathered for 243 patients.Data were collected on psychiatric diagnosis and, if medication was prescribed, what class of medication this was. Information on potential confounding factors was also gathered including sex, age, co-morbid psychiatric diagnoses, history of self-harming behaviours and suicide attempts, family set-up, schooling and other support services involved. Information was stored anonymously.Data were coded. Statistical analysis was undertaken using SPSS (statistical package for the social sciences).ResultsReferrals for psychiatric assessment almost doubled from 83 pre-pandemic to 160 during the first year of the pandemic. Referral rates for most psychiatric disorders increased. The proportion of patients prescribed psychotropic medication increased significantly during the first year of the COVID-19 pandemic compared to the year preceding (P=0.031).Analysis of possible confounding factors was completed. Anti-depressant prescribing rates for those from non-nuclear families increased significantly in the year during the pandemic (P=0.012). Other differences were observed but these were not statistically significant. The numbers of patients who self-harmed, attempted suicide or carried out both increased from 42 to 79.ConclusionFindings add to the existing body of literature highlighting an increase in referrals to mental health services and prescribing of psychotropic medications in the first year of the pandemic in comparison to those pre-pandemic. No clear conclusions could be drawn about factors responsible for change. Continuing to monitor referrals and confounding factors over time would be useful from a public health perspective. It would allow trends to be drawn so that planning can be carried out for future pandemics.
