811 DELIRIUM IN COVID-19: COMMON AND CLINICALLY SIGNIFICANT: EXPERIENCES FROM THE NIGHTINGALE HOSPITAL EXETER

Background

Delirium is an independent predictor of mortality in patients admitted with community-acquired pneumonia (Pieralli, 2014), but significance and incidence in Covid-19 infection has not been established. The Nightingale Hospital Exeter (NHE) as a multidisciplinary team model, managed 242 patients with Covid-19 from November 2020 to February 2021. This study identifies the delirium incidence, outcome, premorbid function and demographics of this cohort.

Methods

Electronic records were retrospectively reviewed for keywords ‘Delirium’, ‘Hyperactive’, ‘Hypoactive’, ‘Confused’ and ‘Muddled’. Patients were categorised as Hyperactive, Hypoactive or Confused/non-specified. Prior functional support (independent, package of care, residential or nursing care) and presence of pre-established neurological conditions (including dementia) were noted.

Results

242 patients were included, average age 84 years (range 59–102). Of these patients, 130 (54%) developed delirium (29 (22%) hyperactive, 37 (28%) hypoactive, 2 (1%) mixed and 62 (48%) ‘confused’/non-specified). Of those with delirium, 56 (43%) were previously living independently and 51 (39%) were living at home with a package of care. 60 (46%) of those diagnosed had no pre-existing neurological condition, 32% had underlying dementia. There were 37 deaths at NHE (mortality 15%), 73% of these patients had delirium during their admission compared to 50% of those who survived.

Conclusions

Over half this cohort developed delirium, a high proportion of whom had been living independently prior to admission with no pre-existing neurological condition, emphasising how common delirium is in patients with Covid-19. In a comparable cohort with pneumonia (mean age 82 years, range 65–99) 25% developed delirium, and it was an independent predictor of in-hospital mortality (Pieralli, 2014). The fact that 73% of all patients who died developed delirium suggests it may have important prognostic implications, and both this and the high incidence indicate further work is required to fully understand how to prevent and manage delirium in Covid-19.

Management of young onset colorectal cancer: divergent practice in the East of England

AIM

According to the revised Bethesda Guidelines, colorectal cancer (CRC) occurring under age 50 years should be screened to exclude Lynch syndrome. However, in current practice in East Anglia, tumour screening is initiated only after genetics referral, reserved for those with a strong pedigree. This study aimed to determine how many patients with young-onset CRC undergo tumour screening in hospitals in East Anglia.

METHOD

A retrospective case notes review over 5 years in four hospitals was undertaken to determine what proportion of those with young-onset CRC underwent referral for tumour screening and to assess local practices in terms of patient counselling and management.

RESULTS

One hundred and twenty-two patients were included. There was an average yearly caseload of 6-9 patients per hospital. Documented family history was rare, as was counselling concerning metachronous and extra-colonic tumour risk and CRC risk in relatives. The rate of referral for genetic testing varied from 44% to 65%. Postoperative colonoscopic surveillance was inconsistent.

CONCLUSION

Many patients with young-onset CRC are managed as sporadic cancers, without Lynch syndrome having been excluded. This may have implications for survival of patients and any affected relatives. A streamlined management algorithm for tumour screening and genetics referral is recommended.
