Introduction Increased mortality has been demonstrated in older adults with COVID-19, but the effect of frailty has been unclear. Methods This multi-centre cohort study involved patients aged 18 years and older hospitalised with COVID-19, using routinely collected data. We used Cox regression analysis to assess the impact of age, frailty, and delirium on the risk of inpatient mortality, adjusting for sex, illness severity, inflammation, and co-morbidities. We used ordinal logistic regression analysis to assess the impact of age, Clinical Frailty Scale (CFS), and delirium on risk of increased care requirements on discharge, adjusting for the same variables. Results Data from 5,711 patients from 55 hospitals in 12 countries were included (median age 74, IQR 54–83; 55.2% male). The risk of death increased independently with increasing age (>80 vs 18–49: HR 3.57, CI 2.54–5.02), frailty (CFS 8 vs 1–3: HR 3.03, CI 2.29–4.00) inflammation, renal disease, cardiovascular disease, and cancer, but not delirium. Age, frailty (CFS 7 vs 1–3: OR 7.00, CI 5.27–9.32), delirium, dementia, and mental health diagnoses were all associated with increased risk of higher care needs on discharge. The likelihood of adverse outcomes increased across all grades of CFS from 4 to 9. Conclusions Age and frailty are independently associated with adverse outcomes in COVID-19. Risk of increased care needs was also increased in survivors of COVID-19 with frailty or older age.

Data relevant to the effects of olanzapine IM are taken from some studies that may not be considered ethical in many places, all are funded by a company with a pecuniary interest in the result. These studies often poorly report outcomes that are difficult to interpret for routine care. Other important outcomes are not recorded at all. Nevertheless, olanzapine IM probably has some value in helping manage acute aggression or agitation, especially where it is necessary to avoid some of the older, better, known treatments. Olanzapine causes fewer movement disorders than haloperidol and more than lorazepam. The value of the oro-dipersable velotab preparation is untested in trials. There is a need for well designed, conducted and reported randomised studies in this area. Such studies are possible and, we argue, should be designed with the patient groups and clinicians in mind. They should report outcomes of relevance to the management of people at this difficult point in their illness.

Clozapine is an effective long-term schizophrenia treatment. The trend to superior effectiveness of olanzapine over risperidone in the long-term has not been reported before and warrants further investigation.

Aims and MethodTo report on the use of atypical antipsychotics in one health district by examining secondary care prescribing patterns for these medicines in North Staffordshire between 1994 and 2001. With one exception, these drugs were licensed solely for use in schizophrenia during the study period.ResultsA total of 502 patients were initiated on atypical antipsychotics in the study period. Of these, 297 (59.2%) had a diagnosis of schizophrenia (ICD–10 codes F20–29). Off-label prescribing was common, but psychiatrists were least likely to prescribe clozapine off-label (2.2%). Affective (18.4%) and organic disorders (12.4%) were the main disorders treated off-label. Olanzapine had the highest off-label use (44.5%).Clinical ImplicationsThe high off-label use of atypical antipsychotics has clinical and economic implications. Although off-label prescribing may be in the patient's best interests, they should be informed and give their consent. Commissioning bodies, such as primary care organisations, are basing their budgets on guidance from the National Institute for Clinical Excellence, which can have implications for funding this off-label use.

Aripiprazole may be effective for the treatment of schizophrenia. Aripiprazole has a lower risk of raised prolactin and prolongation of the QTc interval. Clearly reported pragmatic short-, medium- and long-term randomised controlled trials should be undertaken to determine its position in everyday clinical practice.
