Sedentary Behaviour in the Secure Forensic Hospital Setting: A Study from Dundrum Hospital Ireland

Introduction

Secure forensic mental health services offer care and treatment to mentally disordered offenders, with high rates of schizophrenia and major mental illness in these groups. Much of the excess morbidity and mortality seen among patients with schizophrenia is due to cardiovascular disease and obesity. Sedentary behaviour is associated with negative symptoms of schizophrenia and obesity.

Objectives

The aim of this study was to ascertain the level of sedentary behaviour among inpatients in a secure forensic psychiatric hospital, Dundrum, Ireland, using a structured self-report measure of sedentary behaviours, the SIT-Q tool.

Methods

A cross sectional study of self-reported sedentary behaviour was completed amongst the secure forensic inpatient population of Dundrum Hospital (N=94). Demographic details, details pertaining to diagnoses, ward level of dependency and length of stay were collated.

Results

The majority of patients in the sample were male (89%) and the most common diagnosis was schizophrenia (71.7%). Mean age was 44.7 years (SD 11.42). 58.2% met criteria for obesity. We found high rates of self-reported sedentary behaviour across all wards of the service, with significantly high rates of sedentary behaviour being associated with screen time use in the hospital, including both personal screen time and therapeutic sessions based on screen time.

Conclusions

Sedentary behaviour among in-patients in secure forensic hospitals is a significant issue. Measuring sedentary behaviour in a systematic manner is possible and identifies a potentially modifiable target to reduce co-morbidity and pre-mature mortality independent of other risk factors in this vulnerable patient group.

COVID-19 in forensic psychiatry settings: The unique vulnerability of patients in secure services

Introduction

Secure forensic mental health services treat patient with high rates of treatment resistant psychoses, typically schizophrenia. These groups have high rates of obesity and medical co-morbidities. Population based studies have identified high risk groups in the event of SARS-CoV-2 infection, including those with long term medical conditions.

Objectives

The aim of this study was to compare the vulnerability to serious adverse outcome in the event of COVID-19 infection in a forensic psychiatric patient population.

Methods

All patients of a complete National Forensic Mental Health Service (n=141) were rated for risk of adverse outcome in the event of SARS-CoV-2 infection, using two structured tools, the COVID-AGE tool and the COVID-Risk tool.

Results

Eighty-two patients (58.2%) met criteria for obesity, 32 had type II diabetes and 28 were hypertensive. Mean chronological age was 45.5 years (SD 11.4, median 44.1), while mean COVID-AGE was 59.1 years (SD 19.4, median 58.0), mean difference 13.6 years (SD 15.6) paired t=10.9, df=140, p=0.000. Three patients (2.1%) were chronologically over 70 years compared to 40 (28.4%) with a COVID-AGE over 70 (X2=6.99, df=1, p=0.008, Fishers exact test p=0.027).

Conclusions

These risk assessments may identify the extent of increased risk among a uniquely medically vulnerable patient group. Patients in secure forensic psychiatric services represent a high-risk group for adverse outcomes in the event of SARS-COV-2 infection. Population based cocooning and self-isolating guidance based on chronological age may not be sufficient. There is an urgent need for better physical health research and treatment in this group.

Improving practice in radiology: a quality-improvement project examining CT colonography patient dose and scanning technique

AIM

To audit scanning technique and patient doses for computed tomography (CT) colonography (CTC) examinations in a large UK region and to identify opportunities for quality improvement.

MATERIALS AND METHODS

Scanning technique and patient dose data were gathered for both contrast-enhanced and unenhanced CTC examinations from 33 imaging protocols across 27 scanners. Measurements of patient weight and effective diameter were also obtained. Imaging protocols were compared to identify technique differences between similar scanners. Scanner average doses were calculated and combined to generate regional diagnostic reference limits (DRLs) for both examinations.

RESULTS

The regional DRLs for contrast-enhanced examinations were volume CT dose index (CTDIvol) of 11 and 5 mGy for the two scan phases (contrast-enhanced and either delayed phase or non-contrast enhanced respectively), and dose-length product (DLP) of 740 mGy·cm. For unenhanced examinations, these were 5 mGy and 450 mGy·cm. These are notably lower than the national DRLs of 11 mGy and 950 mGy·cm. Substantial differences in scan technique and doses on similar scanners were identified as areas for quality-improvement action.

CONCLUSION

A regional CTC dose audit has demonstrated compliance with national DRLs but marked variation in practice between sites for the dose delivered to patients, notably when scanners of the same type were compared for the same indication. This study demonstrates that the national DRL is too high for current scanner technology and should be revised.

Gravity steam reprocessing in healthcare facilities for the reuse of N95 respirators

BACKGROUND

Coronavirus disease 2019 (COVID-19) has significantly impacted the health of millions of people around the world. The shortage of personal protective equipment, including N95 respirators, in hospital facilities has put frontline healthcare professionals at high risk for contracting this virus.

AIM

To develop a reproducible and safe N95 respirator reprocessing method that satisfies all presented regulatory standards and that can be directly implemented by hospitals using existing available equipment.

METHODS

A non-toxic gravity steam reprocessing method has been developed for the reuse of N95 respirators consisting of 30 min of steam treatment at 121°C followed by 30 min of heat drying. Samples of model number 1860, 1860s, 1870+, and 9105 N95 respirators were either collected from hospitals (for microbiology testing) or purchased new (for functionality testing), with all functionality tests (i.e. filter efficiency, fit evaluation, and strap integrity) performed at the Centers for Disease Control and Prevention using standard procedures established by the National Institute for Occupational Safety and Health.

FINDINGS

All tested models passed the minimum filter efficiency of 95% after three cycles of gravity steam reprocessing. The 1870+ N95 respirator model is the most promising model for reprocessing based on its efficient bacterial inactivation coupled with the maintenance of all other key functional respirator properties after multiple reprocessing steps.

CONCLUSIONS

The gravity steam method can effectively reprocess N95 respirators over at least three reprocessing cycles without negatively impacting the functionality requirements set out by regulators. Enabling the reuse of N95 respirators is a crucial tool for managing both the current pandemic and future healthcare crises.

Breast screening and ethnic minorities

The concern for minority ethnic women is whether they are disadvantaged either in terms of the incidence of breast cancer or because of a lower uptake of screening. There are considerable worldwide variations in the incidence of breast cancer. The lowest rates are found in Chinese, Japanese and Arabic populations and women from the Indian subcontinent, and are 2-3 times lower than that of the UK. This may change in future generations. Although minority ethnic women are not a high risk group for the breast screening programme, in absolute terms breast cancer is a major health problem. Very few studies have measured ethnic differences in the uptake of screening, and they may be confounded by such factors as socio-economic group. When this is accounted for, uptake by Asian women may not necessarily be lower than by other women in the same area and can be higher for black than white women. One of the most important reasons for non-attendance is inaccurate screening registers, compounded for Asian women by their return, or extended visits, to the Indian subcontinent. A further organisational issue concerns poor awareness of minority ethnic naming systems, causing confusion over the receipt of invitations. Comprehension of the concept of screening may be difficult for minority ethnic women yet there has been little evaluation of strategies to promote understanding. However a randomised controlled trial of a linkworker intervention, designed to be feasible for implementation on a population basis, showed no increase in the uptake of breast screening by Asian women. This does not undermine linkworkers' role but suggests that their efforts should be used in other ways. It is essential to assess the relative importance of reasons for low uptake and evaluate measures to meet any unmet need, so that resources can be directed in the most effective way.

Can the uptake of breast screening by Asian women be increased? A randomized controlled trial of a linkworker intervention

This study investigates the effectiveness of a linkworker intervention, giving encouragement and explanations about breast screening, on the subsequent attendance for screening by 'Asian' women. The control group received no visits. The study population comprised all women with Asian names, from a batch of general practices where high proportions of patients were Asian, who were invited for screening. It was found that 59 per cent of the intervention group could be contacted by linkworkers. No difference in attendance was found between the intervention and control groups (49 per cent and 47 per cent). Twenty-five per cent of women were permanently or temporarily not resident at the invitation address. Attendance for screening was related to length of stay in the United Kingdom. This type of intervention was not a successful strategy for promoting uptake by Asian women, and indicates that it is essential to evaluate rigorously projects with such objectives.

Outpatient clinic referrals and their outcome

A cohort of 392 patients referred to six outpatient clinics by general practitioners during 1987 with diagnoses of rheumatoid arthritis, osteoarthritis, peripheral vascular disease, psoriasis or eczema, were studied from the time of their first attendance until up to two years later. Six consultant clinics were studied in the three specialties: rheumatology, vascular surgery and dermatology. For each specialty a clinic in both a teaching hospital and a district general hospital were included. The cohort members were predominantly middle-aged or elderly people, with a greater proportion of women, except at the vascular surgery clinic where 65% of patients were men. The 392 patients made a total of 936 visits (median two, range one-eight) during the study period; 91 patients were still attending up to two years after the first visit. Patients referred by their general practitioner for therapy were less likely to be discharged than those referred for other reasons. The principal reason for continuing attendance as perceived by patients, general practitioners and hospital doctors was the necessity for consultant supervision, although agreement was far from complete in individual cases. Junior staff tended to see a higher proportion of patients at follow-up visits than did consultants, and were found to have lower discharge rates than consultants. Analyses of data showed that at the first visit, diagnosis, disease severity and the grade of doctor seeing the patient in the clinic was significantly associated with patient discharge at the P < 0.05 level of significance. Patients considered that their visits had produced improvement in their condition in 38% of cases.(ABSTRACT TRUNCATED AT 250 WORDS)
