Timing of radiotherapy (RT) after radical prostatectomy (RP): long-term outcomes in the RADICALS-RT trial (NCT00541047)

BACKGROUND

The optimal timing of radiotherapy (RT) after radical prostatectomy for prostate cancer has been uncertain. RADICALS-RT compared efficacy and safety of adjuvant RT versus an observation policy with salvage RT for prostate-specific antigen (PSA) failure.

PATIENTS AND METHODS

RADICALS-RT was a randomised controlled trial enrolling patients with ≥1 risk factor (pT3/4, Gleason 7-10, positive margins, preoperative PSA≥10 ng/ml) for recurrence after radical prostatectomy. Patients were randomised 1:1 to adjuvant RT ('Adjuvant-RT') or an observation policy with salvage RT for PSA failure ('Salvage-RT') defined as PSA≥0.1 ng/ml or three consecutive rises. Stratification factors were Gleason score, margin status, planned RT schedule (52.5 Gy/20 fractions or 66 Gy/33 fractions) and treatment centre. The primary outcome measure was freedom-from-distant-metastasis (FFDM), designed with 80% power to detect an improvement from 90% with Salvage-RT (control) to 95% at 10 years with Adjuvant-RT. Secondary outcome measures were biochemical progression-free survival, freedom from non-protocol hormone therapy, safety and patient-reported outcomes. Standard survival analysis methods were used; hazard ratio (HR)<1 favours Adjuvant-RT.

RESULTS

Between October 2007 and December 2016, 1396 participants from UK, Denmark, Canada and Ireland were randomised: 699 Salvage-RT, 697 Adjuvant-RT. Allocated groups were balanced with a median age of 65 years. Ninety-three percent (649/697) Adjuvant-RT reported RT within 6 months after randomisation; 39% (270/699) Salvage-RT reported RT during follow-up. Median follow-up was 7.8 years. With 80 distant metastasis events, 10-year FFDM was 93% for Adjuvant-RT and 90% for Salvage-RT: HR=0.68 [95% confidence interval (CI) 0.43-1.07, P=0.095]. Of 109 deaths, 17 were due to prostate cancer. Overall survival was not improved (HR=0.980, 95% CI 0.667-1.440, P=0.917). Adjuvant-RT reported worse urinary and faecal incontinence 1 year after randomisation (P=0.001); faecal incontinence remained significant after 10 years (P=0.017).

CONCLUSION

Long-term results from RADICALS-RT confirm adjuvant RT after radical prostatectomy increases the risk of urinary and bowel morbidity, but does not meaningfully improve disease control. An observation policy with salvage RT for PSA failure should be the current standard after radical prostatectomy.

Reporting of paediatric osteoporotic vertebral fractures in Duchenne muscular dystrophy and potential impact on clinical management: the need for standardised and structured reporting

BACKGROUND

In boys with Duchenne muscular dystrophy (DMD), initiation of bisphosphonate is recommended upon identification of moderate or severe vertebral fractures, even if asymptomatic. Clear radiological reporting is important for consistency of clinical interpretation and management.

OBJECTIVES

To audit radiology reports of spine imaging for vertebral fracture assessment in DMD, and assess potential impact on diagnosis and management.

MATERIALS AND METHODS

Lateral thoracolumbar spine imaging (71 lateral spine radiographs and 13 lateral dual energy absorptiometry spine image) in 84 boys with DMD performed across two centres. Anonymised radiology reports by paediatric radiologists were circulated to two neuromuscular clinicians and two endocrinologists. Clinicians determined if there was vertebral fracture, no vertebral fracture, or unclear interpretation. Endocrinologists also determined if bisphosphonate was indicated. A single observer (a clinician with expertise in vertebral fracture assessment) performed vertebral fracture assessment in 37 images and re-reported using a structured format. Structured reports were re-circulated to the four clinicians to re-evaluate the degree of concordance in clinical diagnosis of vertebral fracture and treatment decisions with bisphosphonate.

RESULTS

The term "fracture" was used in 25/84 (30%) radiology reports and only in 8/43 (19%) with description of vertebral body abnormalities. Fracture grading was included in 7/43 (16%) radiology reports. Diagnostic concordance by the clinicians was noted in 36/84 (43%). Unclear interpretation was noted in 22% to 51% based on radiology reports. No unclear interpretation was noted with structured reports. Complete diagnostic (37/37, 100%) and treatment (37/37, 100%) concordance was noted with the structured reports, whereas complete diagnostic and treatment concordance was noted in only 16/37 (43%) and 17/37 (46%) of the radiology reports, respectively.

CONCLUSION

Only a third of radiology reports of spine imaging in DMD explicitly used the terminology "fracture". Grading was only noted in a small percentage. Variability in diagnostic interpretation by clinicians may lead to differing management plans. As identification of vertebral fracture is a trigger for treatment, developing reporting guidelines for paediatric vertebral fracture assessment will improve care. A structured template should be introduced for radiological reporting of paediatric vertebral fracture assessment.

Understanding covid-19 outcomes among people with intellectual disabilities in England

BACKGROUND

Evidence from the UK from the early stages of the covid-19 pandemic showed that people with Intellectual Disabilities (ID) had higher rates of covid-19 mortality than people without ID. However, estimates of the magnitude of risk vary widely; different studies used different time periods; and only early stages of the pandemic have been analysed. Existing analyses of risk factors have also been limited. The objective of this study was to investigate covid-19 mortality rates, hospitalisation rates, and risk factors in people with ID in England up to the end of 2021.

METHODS

Retrospective cohort study of all people with a laboratory-confirmed SARS-CoV-2 infection or death involving covid-19. Datasets covering primary care, secondary care, covid-19 tests and vaccinations, prescriptions, and deaths were linked at individual level.

RESULTS

Covid-19 carries a disproportionately higher risk of death for people with ID, above their already higher risk of dying from other causes, in comparison to those without ID. Around 2,000 people with ID had a death involving covid-19 in England up to the end of 2021; approximately 1 in 180. The covid-19 standardized mortality ratio was 5.6 [95% CI 5.4, 5.9]. People with ID were also more likely to be hospitalised for covid-19 than people without ID. The main determinants of severe covid-19 outcomes (deaths and/or hospitalisations) in both populations were age, multimorbidity and vaccination status. The key factor responsible for the higher risk of severe covid-19 in the ID population was a much higher prevalence of multimorbidity in this population. AstraZeneca vaccine was slightly less effective in preventing severe covid-19 outcomes among people with ID than among people without ID.

CONCLUSIONS

People with ID should be considered a priority group in future pandemics, such as shielding and vaccinations.

Child oral health and preventive dental service access among children with intellectual disabilities, autism and other educational additional support needs: A population‐based record linkage cohort study

OBJECTIVE

Inequalities in child oral health are a global challenge and the intersection of socioeconomic factors with educational additional support needs (ASN), including children with intellectual disabilities or autism, have thus far received limited attention in relatively small clinical studies. We aimed to address this evidence gap by investigating oral health and access to preventive dental services among children with ASN compared to the general child population.

METHODS

Cohort study linking data from six Scotland-wide health and education databases compared: dental caries experience and tooth extraction via general anaesthetic; receipt of school-based dental inspection; access to primary care and hospital dental services; and access to the Childsmile national oral health improvement programme between children with a range of ASN (intellectual disabilities, autism, social and other) and their peers for the school years 2016/17-2018/19 (n = 166 781).

RESULTS

Children with any ASN had higher rates of caries experience than those with no ASN, however, after adjustment for socioeconomic deprivation, sex, year, and school type only those with a social or other ASN remained at increased risk. Rates of tooth extraction under general anaesthesia in hospital were higher among children with intellectual disabilities (aRR = 1.67;95% CI = [1.16-2.37]). School-based dental inspection access improved for children with intellectual disability and/or autism from 2016/17 onwards, although higher rates of child refusal on the day were observed in these groups (no ASN refusal: 5.4%; intellectual disability: 35.8%; autism: 40.3%). Children with any ASN were less likely to attend primary dental-care regularly, and in those who attended, children with intellectual disability or autism were less likely than their peers to receive prevention (fluoride varnish, oral-hygiene instruction, or dietary advice). Childsmile nursery-supervised toothbrushing programme access among children with any ASN was similar to children with no ASN and children with intellectual disability (aRR = 1.27;95% CI = [1.12-1.45]) or autism (aRR = 1.32;95% CI = [1.19-1.45]) were more likely to receive support from Childsmile dental health support worker.

CONCLUSIONS

We have identified inequalities in oral health and dental care for children with different ASN in Scotland with both a greater burden of disease among some groups and higher complexity of care; compounded by reduced and variable access to preventive dental services. Further efforts are needed to develop and improve preventive care pathways for children with ASN and integrate oral health to wider healthcare systems for these children to mitigate against oral health inequalities.

A study on prescriptions contributing to the risk of high anticholinergic burden in adults with intellectual disabilities: retrospective record linkage study

BACKGROUND

People with intellectual disabilities may face a disproportionate risk of experiencing high anticholinergic burden, and its negative sequalae, from a range of medications, and at younger ages than the general population, but there has been little previous study. Our aim was to determine the source of anticholinergic burden from prescribed medication.

METHODS

Retrospective matched observational study using record linkage. Adults with (n = 4,305), and without (n = 12,915), intellectual disabilities matched by age-, sex- and neighbourhood deprivation. The main outcome measure was the prescription of long-term (approximately 12 months use) anticholinergic medications overall (classified according to the Anticholinergic Risk Scale [ARS]), by drug class, individual drugs, and polypharmacy.

RESULTS

Adults with n = 1,654 (38.4%), and without n = 3,047 (23.6%), intellectual disabilities were prescribed medications long-term with anticholinergic effects. Of those on such drugs, adults with intellectual disabilities were most likely to be on central nervous system (62.6%), gastrointestinal (46.7%), and cardiovascular (28.4%) medications. They were prescribed more central nervous system, gynaecological/urinary tract, musculoskeletal, and respiratory medications, and less cardiovascular, infection, and endocrine medications than their matched comparators. Regardless of age, sex, or neighbourhood deprivation, adults with intellectual disabilities had greater odds of being prescribed antipsychotics (OR = 5.37 [4.40-6.57], p < 0.001), antiepileptics (OR = 2.57 [2.22-2.99], p < 0.001), and anxiolytics/hypnotics (OR = 1.28 [1.06-1.56], p = 0.012). Compared to the general population, adults with intellectual disabilities were more likely to be exposed to overall anticholinergic polypharmacy (OR = 1.48 [1.33-1.66], p < 0.001), and to psychotropic polypharmacy (OR = 2.79 [2.41-3.23], p < 0.001).

CONCLUSIONS

Adults with intellectual disabilities are exposed to a greater risk of having very high anticholinergic burden through polypharmacy from several classes of medications, which may be prescribed by several different prescribers. There is a need for evidence-based recommendations specifically about people with intellectual disabilities with multiple physical and mental ill-health conditions to optimise medication use, reduce inappropriate prescribing and adverse anticholinergic effects.

Analysis of rare disruptive germline mutations in 2,135 enriched BRCA-negative breast cancers excludes additional high-impact susceptibility genes

BACKGROUND

Breast cancer has a significant heritable basis, of which approximately 60% remains unexplained. Testing for BRCA1/BRCA2 offers useful discrimination of breast cancer risk within families, and identification of additional breast cancer susceptibility genes could offer clinical utility.

PATIENTS AND METHODS

We included 2,135 invasive breast cancer cases recruited via the BOCS study, a retrospective UK study of familial breast cancer.

ELIGIBILITY CRITERIA

female, BRCA-negative, white European ethnicity, and one of: i) breast cancer family history, ii) bilateral disease, iii) young age of onset (<30 years), iv) concomitant ovarian cancer. We undertook exome sequencing of cases and performed gene-level burden testing of rare damaging variants against those from 51,377 ethnicity-matched population controls from gnomAD.

RESULTS

159/2135 (7.4%) cases had a qualifying variant in an established breast cancer susceptibility gene, with minimal evidence of signal in other cancer susceptibility genes. Known breast cancer susceptibility genes PALB2, CHEK2 and ATM were the only genes to retain statistical significance after correcting for multiple testing. Due to the enrichment of hereditary cases in the series, we had good power (>80%) to detect a gene of BRCA1-like risk (odds ratio = 10.6) down to a population minor allele frequency of 4.6 x 10^-5 (1 in 10,799, less than one tenth that of BRCA1)and of PALB2-like risk (odds ratio = 5.0) down to a population minor allele frequency of 2.8 x 10^-4 (1 in 1,779, less than half that of PALB2). Power was lower for identification of novel moderate penetrance genes (odds ratio = 2-3) like CHEK2 and ATM.

CONCLUSIONS

This is the largest case-control whole-exome analysis of enriched breast cancer published to date. Whilst additional breast cancer susceptibility genes likely exist, those of high penetrance are likely to be of very low mutational frequency. Contention exists regarding the clinical utility of such genes.

Rates, causes and predictors of all-cause and avoidable mortality in 163 686 children and young people with and without intellectual disabilities: a record linkage national cohort study

OBJECTIVES

To investigate mortality rates and associated factors, and avoidable mortality in children/young people with intellectual disabilities.

DESIGN

Retrospective cohort; individual record-linked data between Scotland's 2011 Census and 9.5 years of National Records for Scotland death certification data.

SETTING

General community.

PARTICIPANTS

Children and young people with intellectual disabilities living in Scotland aged 5-24 years, and an age-matched comparison group.

MAIN OUTCOME MEASURES

Deaths up to 2020: age of death, age-standardised mortality ratios (age-SMRs); causes of death including cause-specific age-SMRs/sex-SMRs; and avoidable deaths.

RESULTS

Death occurred in 260/7247 (3.6%) children/young people with intellectual disabilities (crude mortality rate=388/100 000 person-years) and 528/156 439 (0.3%) children/young people without intellectual disabilities (crude mortality rate=36/100 000 person-years). SMRs for children/young people with versus those without intellectual disabilities were 10.7 for all causes (95% CI 9.47 to 12.1), 5.17 for avoidable death (95% CI 4.19 to 6.37), 2.3 for preventable death (95% CI 1.6 to 3.2) and 16.1 for treatable death (95% CI 12.5 to 20.8). SMRs were highest for children (27.4, 95% CI 20.6 to 36.3) aged 5-9 years, and lowest for young people (6.6, 95% CI 5.1 to 8.6) aged 20-24 years. SMRs were higher in more affluent neighbourhoods. Crude mortality incidences were higher for the children/young people with intellectual disabilities for most International Statistical Classification of Diseases and Related Health Problems, 10th Revision chapters. The most common underlying avoidable causes of mortality for children/young people with intellectual disabilities were epilepsy, aspiration/reflux/choking and respiratory infection, and for children/young people without intellectual disabilities were suicide, accidental drug-related deaths and car accidents.

CONCLUSION

Children with intellectual disabilities had significantly higher rates of all-cause, avoidable, treatable and preventable mortality than their peers. The largest differences were for treatable mortality, particularly at ages 5-9 years. Interventions to improve healthcare to reduce treatable mortality should be a priority for children/young people with intellectual disabilities. Examples include improved epilepsy management and risk assessments, and coordinated multidisciplinary actions to reduce aspiration/reflux/choking and respiratory infection. This is necessary across all neighbourhoods.

COVID-19 infection and outcomes in a population-based cohort of 17 203 adults with intellectual disabilities compared with the general population

BACKGROUND

Adults with intellectual disabilities (ID) may be at higher risk of COVID-19 death. We compared COVID-19 infection, severe infection, mortality, case fatality and excess deaths, among adults with, and without, ID.

METHODS

Adults with ID in Scotland's Census, 2011, and a 5% sample of other adults, were linked to COVID-19 test results, hospitalisation data and deaths (24 January 2020-15 August 2020). We report crude rates of COVID-19 infection, severe infection (hospitalisation/death), mortality, case fatality; age-standardised, sex-standardised and deprivation-standardised severe infection and mortality ratios; and annual all-cause mortality for 2020 and 2015-2019.

FINDINGS

Successful linkage of 94.9% provided data on 17 203 adults with, and 188 634 without, ID. Adults with ID had more infection (905/100 000 vs 521/100 000); severe infection (538/100 000 vs 242/100 000); mortality (258/100 000 vs 116/100 000) and case fatality (30% vs 24%). Poorer outcomes remained after standardisation: standardised severe infection ratio 2.61 (95% CI 1.81 to 3.40) and mortality ratio 3.26 (95% CI 2.19 to 4.32). These were higher at ages 55-64: 7.39 (95% CI 3.88 to 10.91) and 19.05 (95% CI 9.07 to 29.02), respectively, and in men, and less deprived neighbourhoods. All-cause mortality was slightly higher in 2020 than 2015-2019 for people with ID: standardised mortality ratio 2.50 (95% CI 2.18 to 2.82) and 2.39 (95% CI 2.28 to 2.51), respectively.

CONCLUSION

Adults with ID had more COVID-19 infections, and worse outcomes once infected, particularly adults under 65 years. Non-pharmaceutical interventions directed at formal and informal carers are essential to reduce transmission. All adults with ID should be prioritised for vaccination and boosters regardless of age.

Cohort profile: Scotland's record-linkage e-cohorts of people with intellectual disabilities, and autistic people (SCIDA)

PURPOSE

To investigate health, mortality and healthcare inequalities experienced by people with intellectual disabilities, and autistic people, and their determinants; an important step towards identifying and implementing solutions to reduce inequalities. This paper describes the cohorts, record-linkages and variables that will be used.

PARTICIPANTS

Scotland's Census, 2011 was used to identify Scotland's citizens with intellectual disabilities, and autistic citizens, and representative general population samples with neither. Using Scotland's community health index, the Census data (demography, household, employment, long-term conditions) were linked with routinely collected health, death and healthcare data: Scotland's register of deaths, Scottish morbidity data 06 (SMR06: cancer incidence, mortality, treatments), Prescribing Information System (identifying asthma/chronic obstructive pulmonary disease; angina/congestive heart failure/hypertension; peptic ulcer/reflux; constipation; diabetes; thyroid disorder; depression; bipolar disorders; anxiety/sleep; psychosis; attention deficit hyperactivity disorder; epilepsy; glaucoma), SMR01 (general/acute hospital admissions and causes, ambulatory care sensitive admissions), SMR04 (mental health admissions and causes), Scottish Care Information-Diabetes Collaboration (diabetic care quality, diabetic outcomes), national bowel screening programme and cervical screening.

FINDINGS TO DATE

Of the whole population, 0.5% had intellectual disabilities, and 0.6% were autistic. Linkage was successful for >92%. The resultant e-cohorts include: (1) 22 538 people with intellectual disabilities (12 837 men and 9701 women), 4509 of whom are children <16 years, (2) 27 741 autistic people (21 390 men and 6351 women), 15 387 of whom are children <16 years and (3) representative general population samples with neither condition. Very good general health was reported for only 3389 (15.0%) people with intellectual disabilities, 10 510 (38.0%) autistic people, compared with 52.4% general population. Mental health conditions were reported for 4755 (21.1%) people with intellectual disabilities, 3998 (14.4%) autistic people, compared with 4.2% general population.

FUTURE PLANS

Analyses will determine the extent of premature mortality, causes of death, and avoidable deaths, profile of health conditions and cancers, healthcare quality and screening and determinants of mortality and healthcare.

Cefazolin susceptibility of coagulase-negative staphylococci (CoNS) causing late-onset neonatal bacteraemia

BACKGROUND

CoNS bacteraemia causes significant neonatal morbidity. Previous work has suggested that β-lactam antibiotics vary in their binding affinity to PBP2a (produced by the mecA gene) present in most CoNS.

OBJECTIVES

We evaluated cefazolin MICs for CoNS isolated in an Australian neonatal ICU (NICU) and correlated them with isolate genotype and phenotype.

METHODS

Significant blood isolates from 2009 to 2017 were speciated and underwent broth microdilution testing for cefazolin, cefoxitin, oxacillin and flucloxacillin. Correlation with mecA presence and PBP2a expression was evaluated. A selection of Staphylococcus capitis isolates underwent WGS.

RESULTS

The CoNS (n = 99) isolates were confirmed as S. capitis (n = 57), Staphylococcus epidermidis (n = 32), Staphylococcus haemolyticus (n = 2) and Staphylococcus warneri (n = 8). The MIC of cefazolin was ≤2 mg/L for 30% of isolates and 75% had an MIC of ≤8 mg/L (MIC90 = 16 mg/L). This contrasted with MIC90s of cefoxitin, oxacillin and flucloxacillin, which were all ≥32 mg/L. WGS found a number of S. capitis isolates closely related to the globally established NRCS-A clone.

CONCLUSIONS

CoNS displayed distinctly lower MIC values of cefazolin than of other agents tested. MIC variation may be related to binding affinity of PBP2a or regulation of expression of mecA by mecR1-mecI functional genes. Further, NRCS-A S. capitis strains were present in this Australian NICU before and after the unit underwent physical relocation, which raised questions about a common environmental source. It is considered justified to conduct a randomized clinical trial that assesses cefazolin versus vancomycin for management of late-onset neonatal sepsis.

Phase Diagram for Light-Induced Superconductivity in κ-(ET)_{2}-X

Resonant optical excitation of certain molecular vibrations in κ-(BEDT-TTF)_{2}Cu[N(CN)_{2}]Br has been shown to induce transient superconductinglike optical properties at temperatures far above equilibrium T_{c}. Here, we report experiments across the bandwidth-tuned phase diagram of this class of materials, and study the Mott insulator κ-(BEDT-TTF)_{2}Cu[N(CN)_{2}]Cl and the metallic compound κ-(BEDT-TTF)_{2}Cu(NCS)_{2}. We find nonequilibrium photoinduced superconductivity only in κ-(BEDT-TTF)_{2}Cu[N(CN)_{2}]Br, indicating that the proximity to the Mott insulating phase and possibly the presence of preexisting superconducting fluctuations are prerequisites for this effect.

Risk of anticholinergic burden in adults with intellectual disabilities: a Scottish retrospective cohort study of n = 17 220

BACKGROUND

Several drugs have anticholinergic side effects that are associated with adverse health outcomes. Anticholinergic burden studies in adults with intellectual disabilities (ID) have focused exclusively on older adults. This study investigates anticholinergic burden and its associations in adults with ID of all ages (17-94 years).

METHODS

Adults with ID (n = 4 305), each with three general population age-sex-neighbourhood-matched controls (n = 12 915), were linked to their prescribed medications with anticholinergic effects between 2009 and 2017. Analyses were undertaken using logistic regression models.

RESULTS

Adults with ID were more likely to be prescribed any anticholinergic medicines, odds ratio (OR) = 1.49 (1.38-1.59), especially 'very strong' risk medicines, OR = 2.59 (2.39-2.81); 48.5% had very high total anticholinergic burden (3+) compared with 35.4% of the general population, OR = 1.77 (1.64-1.90). This group difference was greater for males, OR = 2.02 (1.84-2.22), than females, OR = 1.48 (1.33-1.65). Adults with ID had significantly higher odds of having very high total anticholinergic burden up to 75 years old, with the greatest group effect occurring in younger ages, 17-24-year-olds, OR = 3.05 (2.39-3.89), and the extent of the difference decreased as age increased. The main effect of neighbourhood deprivation showed greater group differences with increasing affluence of neighbourhood. Results examining only the ID group showed that very high total anticholinergic burden was greatest for females, OR = 1.21 (1.07-1.37), and those over age 55, and extent of neighbourhood deprivation was not significant.

CONCLUSIONS

Adults with ID are at higher risk of anticholinergic burden than the general population, especially young adults. Overall anticholinergic burden increased with age, but burden was high across all ages in the ID group. Very high total anticholinergic burden is prevalent across all types of neighbourhoods for the adults with ID, in contrast to the steeper gradient seen in the general population. Adults with ID have increased likelihood of unintended adverse effects, regardless of potential confounds, so clinicians undertaking medication reviews need to consider anticholinergic side effects and cumulative burden across concomitant medications, including in young adults with ID, not just older adults, and particularly women.

Should cardiac rehabilitation programmes be specifically targeting sedentary time?

Funding Acknowledgements

Type of funding sources: None.

Background / Introduction

Structured exercise classes and advice regarding regular moderate intensity physical activity are well-established components of cardiac rehabilitation (CR). Sedentary behaviour, refers to activities typically sitting or lying that do not substantially increase energy expenditure above resting, and increasing evidence suggests adults should limit their sedentary time to less than 9 hours/day as such behaviour with increased cardiovascular and all-cause mortality with additional benefits likely gained sitting less than 6-8 hours/day. Nonetheless sedentary behaviours are often overlooked or are only partially assessed via self-report in CR programmes. Due to covid restrictions (lockdown, social distancing, suspension of face-to-face CR programmes) there is concern that sedentary time may further increase in this population. Thus, it may be important to effectively monitor and target sedentary time, alongside traditional advice, to minimise its negative health impacts.

Purpose

Can a CR programme, adapted to remote delivery due to covid, objectively measure sedentary behaviour in a way that is feasible in every day practice and acceptable to patients?

Methods

Consecutive cardiovascular patients attending an initial assessment (via telephone or video) on the Our Hearts Our Minds Programme for Cardiovascular Health between December 2020 and February 2021 were asked to wear activPAL (PAL technologies Ltd., Glasgow, UK), a triaxial accelerometer, on their thigh for 7 days to measure the postural aspect of sedentary behaviour. On return of the monitor, the data was analysed using proprietary algorithms (intelligent activity classification) generating a report summarising time spent sitting, prolonged sitting, step count average, number of sit to stand transitions, moderate intensity activity minutes, most sedentary time(s) of the day and percentages spent in these activities. This personalised report was shared with the patient and their goals in terms of sedentary behaviour and physical activity were discussed and agreed.

Results

59 referrals were received between mid December 2020 and February 2021, of which 52 had an initial virtual assessment. Of these, 50 patients accepted an activPAL (96% response rate). Mean age 62.6 years. The output from the activPal is shown in table 1. The average sitting time overall was 9 hours 36 minutes. The breakdown in proportions sitting for extended periods of time are detailed in table below

Conclusion

2/3 of cardiovascular patients attending CR had levels of sitting time greater than what is recommended following their IA. Measuring sedentary time beyond self-report in CR programmes using activPal was feasible in a CR programme with 96% of consecutive patients wearing and returning activPAL.  Repeat analysis at end of programme will show if use of this data results in reduction of same .

Respiratory-associated deaths in people with intellectual disabilities: a systematic review and meta-analysis

OBJECTIVE

To review and synthesise evidence on rates of respiratory-associated deaths and associated risk factors in the intellectual disability population.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Embase, CINAHL, ISI Web of Science (all databases including Medline) and PsychINFO were searched for studies published between 1st January 1985 and 27th April 2020 and examined study and outcome quality. Reference lists and Google Scholar were also hand searched.

RESULTS

We identified 2295 studies, 17 were included in the narrative synthesis and 10 studies (11 cohorts) in the meta-analysis. Data from 90 302 people with intellectual disabilities and 13 808 deaths from all causes in people with intellectual disabilities were extracted. Significantly higher rates of respiratory-associated deaths were found among people with intellectual disabilities (standardised mortality ratio(SMR): 10.86 (95% CI: 5.32 to 22.18, p<0.001) compared with those in the general population, lesser rates for adults with ID (SMR: 6.53 (95% CI: 4.29 to 9.96, p<0.001); and relatively high rates from pneumonia 26.65 (95% CI: 5.63 to 126.24, p<0.001). The overall statistical heterogeneity was I²=99.0%.

CONCLUSION

Premature deaths due to respiratory disorders are potentially avoidable with improved public health initiatives and equitable access to quality healthcare. Further research should focus on developing prognostic guidance and validated tools for clinical practice to mitigate risks of respiratory-associated deaths.

Antipsychotic and antidepressant prescribing for 704 297 children and young people with and without intellectual disabilities: record linkage study

BACKGROUND

Psychotropics are overprescribed for adults with intellectual disabilities; there are few studies in children and young people.

AIMS

To investigate antipsychotic and antidepressant prescribing in children and young people with and without intellectual disabilities, and prescribing trends.

METHOD

Scotland's annual Pupil Census, which identifies pupils with and without intellectual disabilities, was record-linked to the Prescribing Information System. Antidepressant and antipsychotic data were extracted. Logistic regression was used to analyse prescribing between 2010 and 2013.

RESULTS

Of the 704 297 pupils, 16 142 (2.29%) had a record of intellectual disabilities. Antipsychotic and antidepressant use increased over time, and was higher in older pupils; antipsychotic use was higher in boys, and antidepressant use was higher in girls. Overall, antipsychotics were prescribed to 281 (1.74%) pupils with intellectual disabilities and 802 (0.12%) without (adjusted odds ratio 16.85, 95% CI 15.29-18.56). The higher use among those with intellectual disabilities fell each year (adjusted odds ratio 20.19 in 2010 v. 14.24 in 2013). Overall, 191 (1.18%) pupils with intellectual disabilities and 4561 (0.66%) without were prescribed antidepressants (adjusted odds ratio 2.28, 95% CI 2.03-2.56). The difference decreased each year (adjusted odds ratio 3.10 in 2010 v. 2.02 in 2013).

CONCLUSIONS

Significantly more pupils with intellectual disabilities are prescribed antipsychotics and antidepressants than are other pupils. Prescribing overall increased over time, but less so for pupils with intellectual disabilities; either they are not receiving the same treatment advances as other pupils, or possible overprescribing in the past is changing. More longitudinal data are required.

Changes over time in the management of long-term conditions in primary health care for adults with intellectual disabilities, and the healthcare inequality gap

BACKGROUND

Quality of primary healthcare impacts on health outcomes. This study aimed to quantify trends in good practice and the healthcare inequalities gap.

METHOD

Indicators of best-practice management of long-term conditions and health promotion were extracted from primary healthcare records on 721 adults with intellectual disabilities in 2007-2010, and 3638 in 2014. They were compared over time, and with the general population in 2014, using Fisher's Exact test and ordinal regression.

RESULTS

Management improved for adults with intellectual disabilities over time (OR = 5.32; CI = 2.69-10.55), but not for the general population (OR = 0.74; CI = 0.34-1.64). However, it remained poorer, but to a lesser extent, compared with the general population (OR = 0.38; CI = 0.20-0.73 in 2014, and OR = 0.05; CI = 0.02-0.12 in 2007-2010). In 2014, health care was comparable to the general population on 49/78 (62.8%) indicators.

CONCLUSIONS

The extent of the healthcare inequality gap reduced over this period, but remaining inequalities highlight that further action is still necessary.

Dental attendance, restoration and extractions in adults with intellectual disabilities compared with the general population: a record linkage study

BACKGROUND

Oral health may be poorer in adults with intellectual disabilities (IDs) who rely on carer support and medications with increased dental risks.

METHODS

Record linkage study of dental outcomes, and associations with anticholinergic (e.g. antipsychotics) and sugar-containing liquid medication, in adults with IDs compared with age-sex-neighbourhood deprivation-matched general population controls.

RESULTS

A total of 2933/4305 (68.1%) with IDs and 7761/12 915 (60.1%) without IDs attended dental care: odds ratio (OR) = 1.42 [1.32, 1.53]; 1359 (31.6%) with IDs versus 5233 (40.5%) without IDs had restorations: OR = 0.68 [0.63, 0.73]; and 567 (13.2%) with IDs versus 2048 (15.9%) without IDs had dental extractions: OR = 0.80 [0.73, 0.89]. Group differences for attendance were greatest in younger ages, and restoration/extractions differences were greatest in older ages. Adults with IDs were more likely prescribed with anticholinergics (2493 (57.9%) vs. 6235 (48.3%): OR = 1.49 [1.39, 1.59]) and sugar-containing liquids (1641 (38.1%) vs. 2315 (17.9%): OR = 2.89 [2.67, 3.12]).

CONCLUSION

Carers support dental appointments, but dentists may be less likely to restore teeth, possibly extracting multiple teeth at individual appointments instead.

Association between minimum inhibitory concentration, beta-lactamase genes and mortality for patients treated with piperacillin/tazobactam or meropenem from the MERINO study

INTRODUCTION

This study aims to assess the association of piperacillin/tazobactam and meropenem minimum inhibitory concentration (MIC) and beta-lactam resistance genes with mortality in the MERINO trial.

METHODS

Blood culture isolates from enrolled patients were tested by broth microdilution and whole genome sequencing at a central laboratory. Multivariate logistic regression was performed to account for confounders. Absolute risk increase for 30-day mortality between treatment groups was calculated for the primary analysis (PA) and the microbiologic assessable (MA) populations.

RESULTS

320 isolates from 379 enrolled patients were available with susceptibility to piperacillin/tazobactam 94% and meropenem 100%. The piperacillin/tazobactam non-susceptible breakpoint (MIC > 16 mg/L) best predicted 30-day mortality after accounting for confounders (odds ratio 14.9, 95% CI 2.8 - 87.2). The absolute risk increase for 30-day mortality for patients treated with piperacillin/tazobactam compared with meropenem was 9% (95% CI 3% - 15%) and 8% (95% CI 2% - 15%) for the original PA population and the post-hoc MA populations, which reduced to 5% (95% CI -1% - 10%) after excluding strains with piperacillin/tazobactam MIC values > 16 mg/L. Isolates co-harboring ESBL and OXA-1 genes were associated with elevated piperacillin/tazobactam MICs and the highest risk increase in 30-mortality of 14% (95% CI 2% - 28%).

CONCLUSION

After excluding non-susceptible strains, the 30-day mortality difference was from the MERINO trial was less pronounced for piperacillin/tazobactam. Poor reliability in susceptibility testing performance for piperacillin/tazobactam and the high prevalence of OXA co-harboring ESBLs suggests meropenem remains the preferred choice for definitive treatment of ceftriaxone non-susceptible E. coli and Klebsiella.

Is provision of contraception at discharge following delivery associated with postpartum visit attendance?

OBJECTIVES

We examined whether provision of contraception at discharge following delivery was associated with lower rates of postpartum visit (PPV) attendance.

METHODS

We conducted a retrospective cohort study of women who received pregnancy care at a Midwestern medical center in 2013. Attendance at the postpartum visit was compared for women with sterilization, contraception initiated prior to discharge (depot medroxyprogesterone acetate or etonogestrel implant), hormonal contraception prescription, or no contraception provided at postpartum discharge. Poisson regression models with robust standard errors were used to estimate the relative risk of postpartum visit attendance controlling for age, race, and parity, insurance status, and histories of both depression and drug abuse.

RESULTS

Of the 1015 women who met inclusion criteria, 55% had been prescribed contraception, had initiated contraception prior to discharge, or were sterilized at the time of discharge following delivery. After adjustment for confounders, there was no association between receiving contraception and PPV attendance (relative risk for prescribed contraception = 1.09 [95% CI 0.85, 1.39], for contraception initiated prior to discharge = 0.83 [95% CI 0.67, 1.03], for sterilization = 0.86 [95% CI 0.63, 1.17] compared to no contraception).

CONCLUSIONS

We found no evidence that prescribing or administering contraception post-delivery was associated with lower rates of return for postpartum follow up.

IMPLICATIONS

This single site study suggests that providing effective contraception at discharge following delivery does not appear to impact PPV attendance.

Neurodevelopmental multimorbidity and educational outcomes of Scottish schoolchildren: A population-based record linkage cohort study

BACKGROUND

Neurodevelopmental conditions commonly coexist in children, but compared to adults, childhood multimorbidity attracts less attention in research and clinical practice. We previously reported that children treated for attention deficit hyperactivity disorder (ADHD) and depression have more school absences and exclusions, additional support needs, poorer attainment, and increased unemployment. They are also more likely to have coexisting conditions, including autism and intellectual disability. We investigated prevalence of neurodevelopmental multimorbidity (≥2 conditions) among Scottish schoolchildren and their educational outcomes compared to peers.

METHODS AND FINDINGS

We retrospectively linked 6 Scotland-wide databases to analyse 766,244 children (390,290 [50.9%] boys; 375,954 [49.1%] girls) aged 4 to 19 years (mean = 10.9) attending Scottish schools between 2009 and 2013. Children were distributed across all deprivation quintiles (most to least deprived: 22.7%, 20.1%, 19.3%, 19.5%, 18.4%). The majority (96.2%) were white ethnicity. We ascertained autism spectrum disorder (ASD) and intellectual disabilities from records of additional support needs and ADHD and depression through relevant encashed prescriptions. We identified neurodevelopmental multimorbidity (≥2 of these conditions) in 4,789 (0.6%) children, with ASD and intellectual disability the most common combination. On adjusting for sociodemographic (sex, age, ethnicity, deprivation) and maternity (maternal age, maternal smoking, sex-gestation-specific birth weight centile, gestational age, 5-minute Apgar score, mode of delivery, parity) factors, multimorbidity was associated with increased school absenteeism and exclusion, unemployment, and poorer exam attainment. Significant dose relationships were evident between number of conditions (0, 1, ≥2) and the last 3 outcomes. Compared to children with no conditions, children with 1 condition, and children with 2 or more conditions, had more absenteeism (1 condition adjusted incidence rate ratio [IRR] 1.28, 95% CI 1.27-1.30, p < 0.001 and 2 or more conditions adjusted IRR 1.23, 95% CI 1.20-1.28, p < 0.001), greater exclusion (adjusted IRR 2.37, 95% CI 2.25-2.48, p < 0.001 and adjusted IRR 3.04, 95% CI 2.74-3.38, p < 0.001), poorer attainment (adjusted odds ratio [OR] 3.92, 95% CI 3.63-4.23, p < 0.001 and adjusted OR 12.07, 95% CI 9.15-15.94, p < 0.001), and increased unemployment (adjusted OR 1.57, 95% CI 1.49-1.66, p < 0.001 and adjusted OR 2.11, 95% CI 1.83-2.45, p < 0.001). Associations remained after further adjustment for comorbid physical conditions and additional support needs. Coexisting depression was the strongest driver of absenteeism and coexisting ADHD the strongest driver of exclusion. Absence of formal primary care diagnoses was a limitation since ascertaining depression and ADHD from prescriptions omitted affected children receiving alternative or no treatment and some antidepressants can be prescribed for other indications.

CONCLUSIONS

Structuring clinical practice and training around single conditions may disadvantage children with neurodevelopmental multimorbidity, who we observed had significantly poorer educational outcomes compared to children with 1 condition and no conditions.

Changes over a decade in psychotropic prescribing for people with intellectual disabilities: prospective cohort study

OBJECTIVES

To investigate psychotropic prescribing in the intellectual disabilities population over 10 years, and associated mental ill health diagnoses.

DESIGN

Comparison of cross-sectional data in 2002-2004 (T1) and 2014 (T2). Longitudinal cohort study with detailed health assessments at T1 and record linkage to T2 prescribing data.

SETTING

General community.

PARTICIPANTS

1190 adults with intellectual disabilities in T1 compared with 3906 adults with intellectual disabilities in T2. 545/1190 adults with intellectual disabilities in T1 were alive and their records linked to T2 prescribing data.

MAIN OUTCOME MEASURES

Encashed regular and as-required psychotropic prescriptions.

RESULTS

50.7% (603/1190) of adults in T1 and 48.2% (1881/3906) in T2 were prescribed at least one psychotropic; antipsychotics: 24.5% (292/1190) in T1 and 16.7% (653/3906) in T2; antidepressants: 11.2% (133/1190) in T1 and 19.1% (746/3906) in T2. 21.2% (62/292) prescribed antipsychotics in T1 had psychosis or bipolar disorder, 33.2% (97/292) had no mental ill health or problem behaviours, 20.6% (60/292) had problem behaviours but no psychosis or bipolar disorder. Psychotropics increased from 47.0% (256/545) in T1 to 57.8% (315/545) in T2 (p<0.001): antipsychotics did not change (OR 1.18; 95% CI 0.87 to 1.60; p=0.280), there was an increase for antidepressants (OR 2.80; 95% CI 1.96 to 4.00; p<0.001), hypnotics/anxiolytics (OR 2.19; 95% CI 1.34 to 3.61; p=0.002), and antiepileptics (OR 1.40; 95% CI 1.06 to 1.84; p=0.017). Antipsychotic prescribing increased for people with problem behaviours in T1 (OR 6.45; 95% CI 4.41 to 9.45; p<0.001), more so than for people with other mental ill health in T1 (OR 4.11; 95% CI 2.76 to 6.11; p<0.001).

CONCLUSIONS

Despite concerns about antipsychotic prescribing and guidelines recommending their withdrawal, it appears that while fewer antipsychotic prescriptions were initiated by T2 than in T1, people were not withdrawn from them once commenced. People with problem behaviours had increased prescribing. There was also a striking increase in antidepressant prescriptions. Adults with intellectual disabilities need frequent and careful medication reviews.

Mortality in 787,666 school pupils with and without autism: A cohort study

Studies on children and adults combined suggest higher mortality rates for autistic than other people, but few report mortality rates for autistic children. In addition, past studies may not be representative of the current generation of children diagnosed with autism. We examined mortality in children using data from Scotland’s annual pupil census, linked to National Records of Scotland deaths register, between 2008 and 2015. In total, 9754 (1.2%) of 787,666 pupils had autism. They were more likely to live in neighbourhoods of greater deprivation and receive free school meals. Six autistic pupils died; crude mortality rate 15.8/100,000 person-years (95% CI = 7.1–35.1), compared with 458 other pupils; crude mortality rate 12.5/100,000 person-years (95% CI = 11.4–13.7). The indirectly standardised mortality ratio was 1.1 (95% CI = 0.5–2.5). In the autistic pupils, the most common causes of death were nervous system diseases, for example, epilepsy. Avoidable causes were common. In the comparison group, external causes and cancers were the most common causes of death. We cautiously conclude that mortality in the current generation of autistic children is no higher than for other children, perhaps due to recent widening of criteria for autism spectrum diagnosis, but some deaths could have been avoided by better care.

Rates and causes of mortality among children and young people with and without intellectual disabilities in Scotland: a record linkage cohort study of 796 190 school children

OBJECTIVES

To investigate mortality rates and causes in children and young people with intellectual disabilities.

DESIGN

Retrospective cohort; individual record linkage between Scotland's annual pupil census and National Records of Scotland death register.

SETTING

General community.

PARTICIPANTS

Pupils receiving local authority-funded schooling in Scotland, 2008 to 2013, with an Additional Support Need due to intellectual disabilities, compared with other pupils.

MAIN OUTCOME MEASURES

Deaths up to 2015: age of death, age-standardised mortality ratios (age-SMRs); causes of death including cause-specific age-SMRs; avoidable deaths as defined by the UK Office of National Statistics.

RESULTS

18 278/947 922 (1.9%) pupils had intellectual disabilities. 106 died over 67 342 person-years (crude mortality rate=157/100 000 person-years), compared with 458 controls over 3 672 224 person-years (crude mortality rate=12/100 000 person-years). Age-SMR was 11.6 (95% CI 9.6 to 14.0); 16.6 (95% CI 12.2 to 22.6) for female pupils and 9.8 (95% CI 7.7 to 12.5) for male pupils. Most common main underlying causes were diseases of the nervous system, followed by congenital anomalies; most common all-contributing causes were diseases of the nervous system, followed by respiratory system; most common specific contributing causes were cerebral palsy, pneumonia, respiratory failure and epilepsy. For all contributing causes, SMR was 98.8 (95% CI 69.9 to 139.7) for congenital anomalies, 76.5 (95% CI 58.9 to 99.4) for nervous system, 63.7 (95% CI 37.0 to 109.7) for digestive system, 55.3 (95% CI 42.5 to 72.1) for respiratory system, 32.1 (95% CI 17.8 to 57.9) for endocrine and 14.8 (95% CI 8.9 to 24.5) for circulatory system. External causes accounted for 46% of control deaths, but the SMR for external-related deaths was still higher (3.6 (95% CI 2.2 to 5.8)) for pupils with intellectual disabilities. Deaths amenable to good care were common.

CONCLUSION

Pupils with intellectual disabilities were much more likely to die than their peers, and had a different pattern of causes, including amenable deaths across a wide range of disease categories. Improvements are needed to reduce amenable deaths, for example, epilepsy-related and dysphagia, and to support families of children with life-limiting conditions.

Rates, causes, place and predictors of mortality in adults with intellectual disabilities with and without Down syndrome: cohort study with record linkage

OBJECTIVES

To investigate mortality in adults with intellectual disabilities: rates, causes, place, demographic and clinical predictors.

DESIGN

Cohort study with record linkage to death data.

SETTING

General community.

PARTICIPANTS

961/1023 (94%) adults (16-83 years; mean=44.1 years; 54.6% male) with intellectual disabilities, clinically examined in 2001-2004; subsequently record-linked to their National Health Service number, allowing linkage to death certificate data, 2018.

OUTCOME MEASURES

Standardised mortality ratios (SMRs), underlying and all contributing causes of death, avoidable deaths, place, and demographic and clinical predictors of death.

RESULTS

294/961 (30.6%) had died; 64/179 (35.8%) with Down syndrome, 230/783 (29.4%) without Down syndrome. SMR overall=2.24 (1.98, 2.49); Down syndrome adults=5.28 (3.98, 6.57), adults without Down syndrome=1.93 (1.68, 2.18); male=1.69 (1.42, 1.95), female=3.48 (2.90, 4.06). SMRs decreased as age increased. More severe intellectual disabilities increased SMR, but ability was not retained in the multivariable model. SMRs were higher for most International Statistical Classification of Diseases and Related Health Problems, 10th Revision chapters. For adults without Down syndrome, aspiration/reflux/choking and respiratory infection were the the most common underlying causes of mortality; for Down syndrome adults 'Down syndrome', and dementia were most common. Amenable deaths (29.8%) were double that in the general population (14%); 60.3% died in hospital. Mortality risk related to percutaneous endoscopic gastrostomy/tube fed, Down syndrome, diabetes, lower respiratory tract infection at cohort-entry, smoking, epilepsy, hearing impairment, increasing number of prescribed drugs, increasing age. Bowel incontinence reduced mortality risk.

CONCLUSIONS

Adults with intellectual disabilities with and without Down syndrome have different SMRs and causes of death which should be separately reported. Both die younger, from different causes than other people. Some mortality risks are similar to other people, with earlier mortality reflecting more multimorbidity; amenable deaths are also common. This should inform actions to reduce early mortality, for example, training to avoid aspiration/choking, pain identification to address problems before they are advanced, and reasonable adjustments to improve healthcare quality.

Birth incidence, deaths and hospitalisations of children and young people with Down syndrome, 1990-2015: birth cohort study

OBJECTIVE

To investigate current Down syndrome live birth and death rates, and childhood hospitalisations, compared with peers.

SETTING

General community.

PARTICIPANTS

All live births with Down syndrome, 1990-2015, identified via Scottish regional cytogenetic laboratories, each age-sex-neighbourhood deprivation matched with five non-Down syndrome controls. Record linkage to Scotland's hospital admissions and death data.

PRIMARY OUTCOME

HRs comparing risk of first hospitalisation (any and emergency), readmission for children with Down syndrome and matched controls were calculated using stratified Cox proportional hazards (PH) model, and length of hospital stay was calculated using a conditional log-linear regression model.

RESULTS

689/1479 (46.6%) female and 769/1479 (51.9%) male children/young people with Down syndrome were identified (1.0/1000 births, with no reduction over time); 1235 were matched. 92/1235 (7.4%) died during the period, 18.5 times more than controls. More of the Down syndrome group had at least one admission (incidence rate ratio(IRR) 72.89 (68.72-77.32) vs 40.51 (39.15-41.92); adjusted HR=1.84 (1.68, 2.01)) and readmissions (IRR 54.85 (51.46-58.46) vs 15.06 (14.36-15.80); adjusted HR=2.56 (2.08, 3.14)). More of their admissions were emergencies (IRR 56.78 (53.13-60.72) vs 28.88 (27.73-30.07); first emergency admission adjusted HR=2.87 (2.61, 3.15)). Children with Down syndrome had 28% longer first admission after birth. Admission rate increased from 1990-2003 to 2004-2014 for the Down syndrome group (from 90.7% to 92.2%) and decreased for controls (from 63.3% to 44.8%).

CONCLUSIONS

We provide contemporaneous statistics on the live birth rate of babies with Down syndrome, and their childhood death rate. They require more hospital admissions, readmissions emergency admissions and longer lengths of stays than their peers, which has received scant research attention in the past. This demonstrates the importance of statutory planning as well as informal support to families to avoid added problems in child development and family bonding over and above that brought by the intellectual disabilities associated with Down syndrome.

The relative influence of intellectual disabilities and autism on sensory impairments and physical disability: A whole-country cohort of 5.3 million children and adults

BACKGROUND

Intellectual disabilities and autism are lifelong and often co-occur. Little is known on their extent of independent association with sensory impairments and physical disability.

METHODS

For Scotland's population, logistic regressions investigated age-gender-adjusted odds ratios (OR) of associations, independently, of intellectual disabilities and autism with sensory impairments and physical disability.

RESULTS

1,548,819 children/youth, and 3,746,584 adults. In children/youth, the effect size of intellectual disabilities and autism, respectively, was as follows: blindness (OR = 30.12; OR = 2.63), deafness (OR = 13.98; OR = 2.31), and physical disability (OR = 43.72; OR = 5.62). For adults, the effect size of intellectual disabilities and autism, respectively, was as follows: blindness (OR = 16.89; OR = 3.29), deafness (OR = 7.47; OR = 2.36), and physical disability (OR = 6.04; OR = 3.16).

CONCLUSIONS

Intellectual disabilities have greater association with the population burden of sensory impairments/physical disability, but autism is also associated regardless of overlap with intellectual disabilities. These may impact further on communication limitations due to autism and intellectual disabilities, increasing complexity of assessments/management of other health conditions. Clinicians need to be aware of these important issues.

Prevalence of factors associated with edentulousness (no natural teeth) in adults with intellectual disabilities

BACKGROUND

Poor oral health is largely preventable. Prevention includes toothbrushing and regular dental checks. Oral health has important consequences for general nutrition, chewing, communication, wider systemic disease, self-confidence and participation in society. This study investigated the prevalence of edentulousness (no natural teeth) in adults with intellectual disabilities (IDs) compared with the general population and associated factors.

METHODS

An adult cohort with IDs residing in Greater Glasgow and Clyde, Scotland, underwent detailed health assessments between 2002 and 2004. Between 2004 and 2006, a subsample had an oral check. Data on edentulousness in the cohort were compared with adult participants from Greater Glasgow and Clyde in the 2008 Scottish Health Survey. Within the IDs cohort, binary logistic regression analyses investigated potential relationships between edentulousness and demographic and clinical factors.

RESULTS

Five hundred sixty adults with IDs were examined [53.2% (298) male, mean age = 46.3 years, range 18-81 years] and compared with 2547 general population: edentulousness was 9% vs. 1% aged 25-34 years; 22% vs. 2% aged 35-44 years; 39% vs. 7% aged 45-54 years; 41% vs. 18% aged 55-64 years; and 76% vs. 34% aged 65-74 years. In both groups, edentulousness increased with age. After stratification for age, rates of edentulousness were consistently higher in the ID cohort. Odds ratios within age strata were not homogenous (Mantel-Haenszel test, P < 0.0001). Edentulousness was more likely in those with more severe IDs (adjusted odds ratio (AOR) = 2.36; 95% confidence interval (CI) [1.23 to 4.51]); those taking antipsychotics (AOR = 2.09; 95% CI [1.25 to 3.51]) and those living in the most deprived neighbourhoods (AOR = 2.69; 95% CI [1.11 to 6.50]). There was insufficient evidence for associations with sex, type of accommodation/support, antiepileptics, problem behaviours or autism.

CONCLUSIONS

Adults with IDs have a high prevalence of edentulousness and need supported daily oral care to reduce the need for extractions. Despite previous reports on poor oral care and the move towards person-centred care, carers and care-giving organisations need greater support to implement daily oral care. Prescribers need awareness of the potentially contributory role of antipsychotics, which may relate to xerostomia.

Identifying the World Health Organization's fifth moment for hand hygiene: Infection prevention in the operating room

Background

The World Health Organization have designed the fifth of their '5 moments' for hand hygiene to account for microbial transfer from patients to equipment in a narrow area around that patient, known as the patient zone. The study was prompted by emerging local confusion about application of the patient zone in the operating room (OR).

Aim/Objectives

In two phases, we aimed to create a '5 moments' style poster displaying an OR patient zone: phase 1, quantify equipment, in direct contact with the patient and, touched by non-scrubbed staff immediately after touching the patient; and phase 2, categorise equipment identified in phase 1 into patient zone and healthcare zone. An objective is to produce a '5 moments' poster for the OR.

Methods

The first phase used non-participant direct overt observation. In phase 2, phase 1 data were collaboratively assigned to patient zone or healthcare zone. Photography and graphic design were used to produce the OR '5 moments' poster.

Results

In 11 full-length surgeries, 20 pieces of equipment were in direct contact with the patient and 57 pieces of equipment were touched. In phase 2, a '5 moments' poster showing an OR patient zone was designed.

Discussion

Content of the patient zone was identified and displayed in a novel resource. Having shared understanding of the patient zone has potential to sustain hand hygiene compliance and equipment cleaning in the OR.

Conclusion

Limitations in methods were balanced by collaboration with frontline staff. The study has been used as a teaching tool in the OR and similar settings.

Neurodevelopmental multimorbidity and educational outcomes of 766,244 Scottish schoolchildren

Background

Neurodevelopmental conditions commonly co-exist in children but, in comparison with adults, childhood multimorbidity has attracted less attention in research and clinical practice.

Methods

Record linkage of five Scotland-wide databases produced a cohort of 766,244 children attending Scottish schools between 2009 and 2013. Autistic spectrum disorder (ASD) and intellectual disabilities were ascertained from records of special educational need in the annual Pupil Census and attention deficit hyperactivity disorder (ADHD) and depression through relevant encashed prescriptions.

Results

Neurodevelopmental multimorbidity (≥2 conditions) was identified in 4,789 (0·6%) children; with ASD and ADHD the most common combination. Multimorbidity was associated with significantly increased risk of school absenteeism (adjusted IRR 1·23, 95% CI 1·20-1·28), school exclusion (adjusted IRR 3·04, 95% CI 2·74-3·38), low attainment (adjusted OR 12·07, 95% CI 9·15-15·94) and unemployment (adjusted OR 2·11, 95% CI 1·83-2·45) with clear dose relationships evident between number of conditions (0, 1, ≥2) and the last three outcomes. The associations with multimorbidity were stronger in girls than boys. Co-existence of depression was the strongest driver of absenteeism and co-existence of ADHD the strongest driver of exclusion. Low attainment and unemployment were, in part, mediated by absence and attainment respectively, and were not driven by specific conditions but rather multimorbidity from any cause.

Conclusions

Structuring clinical practice and training around single conditions may disadvantage children with multimorbidity who are at significantly increased risk of adverse outcomes if their complex needs are not recognised and managed.

Key messages

Neurodevelopmental multimorbidity can have significant impacts on children’s education. A holistic healthcare approach is needed to reduce the address their needs and reduce the risk of adverse outcomes.

Relative influence of intellectual disabilities and autism on mental and general health in Scotland: a cross-sectional study of a whole country of 5.3 million children and adults

OBJECTIVES

To determine the relative extent that autism and intellectual disabilities are independently associated with poor mental and general health, in children and adults.

DESIGN

Cross-sectional study. For Scotland's population, logistic regressions investigated odds of intellectual disabilities and autism predicting mental health conditions, and poor general health, adjusted for age and gender.

PARTICIPANTS

1 548 819 children/youth aged 0-24 years, and 3 746 584 adults aged more than 25 years, of whom 9396/1 548 819 children/youth had intellectual disabilities (0.6%), 25 063/1 548 819 children/youth had autism (1.6%); and 16 953/3 746 584 adults had intellectual disabilities (0.5%), 6649/3 746 584 adults had autism (0.2%). These figures are based on self-report.

MAIN OUTCOME MEASURES

Self-reported general health status and mental health.

RESULTS

In children/youth, intellectual disabilities (OR 7.04, 95% CI 6.30 to 7.87) and autism (OR 25.08, 95% CI 23.08 to 27.32) both independently predicted mental health conditions. In adults, intellectual disabilities (OR 3.50, 95% CI 3.20 to 3.84) and autism (OR 5.30, 95% CI 4.80 to 5.85) both independently predicted mental health conditions. In children/youth, intellectual disabilities (OR 18.34, 95% CI 17.17 to 19.58) and autism (OR 8.40, 95% CI 8.02 to 8.80) both independently predicted poor general health. In adults, intellectual disabilities (OR 7.54, 95% CI 7.02 to 8.10) and autism (OR 4.46, 95% CI 4.06 to 4.89) both independently predicted poor general health.

CONCLUSIONS

Both intellectual disabilities and autism independently predict poor health, intellectual disabilities more so for general health and autism more so for mental health. Intellectual disabilities and autism are not uncommon, and due to their associated poor health, sufficient services/supports are needed. This is not just due to coexistence of these conditions or just to having intellectual disabilities, as the population with autism is independently associated with substantial health inequalities compared with the general population, across the entire life course.

A33 Using serological and surveillance data to infer the introduction date and unobserved transmission dynamics of Zika virus in Fiji 2013–7

Zika virus (ZIKV) has been circulating in the South Pacific since 2007, and transmission in Fiji was first confirmed in 2015. To better understand the history and transmission dynamics of ZIKV in Fiji, we combined a transmission dynamic model with serological and surveillance data from Central Division, Fiji. A longitudinal population representative of seroepidemiological data were available from participants sampled in 2013, 2015, and 2017. In addition, ZIKV case reports were available from 2015 and 2016. Using a Bayesian approach, we fitted a transmission dynamic model with a seasonally varying transmission to these data. We also estimated the virus introduction date, given the effect this has on transmission dynamics as it interacts with the observed seasonal pattern of transmission. We found evidence that the virus was introduced in October 2013 (95% credible interval: April 2013–April 2014) and that the strong seasonal transmission pattern meant the virus persisted for several years with multiple waves of infection in consecutive years. It is important to corroborate this evidence against other work done in the same area. A phylogenetic analysis was performed on 5 ZIKV strains obtained from Fiji in 2015 and 2016, which were aligned with 33 E gene sequences from the Pacific, Americas, and Africa. This analysis showed evidence of virus persistence over multiple years in Central Division, Fiji. The estimated most recent common ancestor of the group isolated from Central Division was November 2013 (95% credible interval: March 2013–July 2015). Our modeling estimate is consistent with these results despite the very different methods being used. The availability of detailed case and serology data in an island outbreak setting, combined with mathematical models, presented a unique opportunity to gain crucial insights into these infections. Our analysis provides evidence that seasonal variation in transmission, combined with other co-circulating flaviviruses, means the timing of ZIKV introduction can have a major impact on outbreak transmission dynamics.

Age at identification, prevalence and general health of children with autism: observational study of a whole country population

OBJECTIVES

Reported childhood prevalence of autism varies considerably between studies and over time, and general health status has been little investigated. We aimed to investigate contemporary prevalence of reported autism by age, and general health status of children/young people with and without autism.

DESIGN

Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study.

SETTING

General population of Scotland.

PARTICIPANTS

All children (n=916 331) and young people (n=632 488) in Scotland.

MAIN OUTCOME MEASURES

Number (%) of children/young people reported to have autism and their general health status; prevalence of autism; prevalence of poor health (fair, bad and very bad health); odds ratios (95% confidence intervals) of autism predicting poor health, adjusted for age and gender and OR for age and gender in predicting poor health within the population with reported autism.

RESULTS

Autism was reported for 17 348/916 331 (1.9%) children aged 0-15, and 7715/632 488 (1.2%) young people aged 16-24. The rate increased to age 11 in boys and age 10 in girls, reflecting age at diagnosis. Prevalence was 2.8% at age 10 (4.4% for boys; 1.1% for girls), and 2.9% at age 11 (4.5% for boys; 1.1% for girls). 22.0% of children and 25.5% of young people with autism reported poor health, compared with 2.0% and 4.4% without autism. Autism had OR=11.3 (11.0 to 11.7) in predicting poor health. Autistic females had poorer health than autistic males, OR=1.6 (1.5 to 1.8).

CONCLUSION

Accurate information on the proportion of autistic children and their health status is essential plan appropriate prevention and intervention measures and provide resources for those who may put demand on services designed for autistic people.

Benzylpenicillin versus flucloxacillin for penicillin-susceptible Staphylococcus aureus bloodstream infections from a large retrospective cohort study

In clinical practice, differing opinions exists regarding the optimal management of patients with penicillin-susceptible Staphylococcus aureus (PSSA) bloodstream infection (BSI). The aim of this study was to compare the 30-day mortality of patients treated with benzylpenicillin or flucloxacillin for PSSA BSI from a large prospectively collected data set from Australia and New Zealand. A logistic regression model and propensity score treatment analysis using inverse probability of treatment weighting were used. A total of 915 patients were included in the study, with an overall mortality rate of 12.9% (118/915) [benzylpenicillin 10.5% (33/315) and flucloxacillin 14.2% (85/600)]. Endocarditis was associated with benzylpenicillin treatment choice, whereas skin and soft-tissue infection was associated with flucloxacillin treatment choice. In the multivariate analysis, increased 30-day mortality was associated with flucloxacillin compared with benzylpenicillin [odds ratio (OR) = 1.6, 95% confidence interval (CI) 1.0-2.5; P = 0.05). When adjusted for treatment choice in the propensity score analysis, flucloxacillin was again associated with increased 30-day mortality (OR = 1.06, 95% CI 1.01-1.1; P = 0.03). An increase in 30-day mortality associated with flucloxacillin use suggests a potential benefit for benzylpenicillin therapy in patients with PSSA BSI.

Uveitis and optic perineuritis in the context of myelin oligodendrocyte glycoprotein antibody seropositivity

BACKGROUND AND PURPOSE

Antibodies to myelin oligodendrocyte glycoprotein (MOG) have been identified in both children and adults with demyelination, with a strong association with bilateral or recurrent optic neuritis (ON). However, the full clinical spectrum of this newly described condition is unknown. We sought to describe non-ON inflammatory ophthalmological presentations such as uveitis and optic perineuritis in the context of MOG antibody seropositivity.

METHODS

Using a live cell-based assay analysed by flow cytometry, we identified seropositive patients referred for MOG antibody testing in Australasia between 2014 and 2017. We identified four MOG antibody-positive patients with non-ON inflammatory ophthalmological presentations and present their detailed clinical information in this case series.

RESULTS

Three patients had uveitis either in association with, or remote from, ON. One patient had optic perineuritis and peripheral ulcerative keratitis. We describe the presentation, examination, investigation findings and clinical course of these four patients.

CONCLUSIONS

Recognition of these novel clinical associations may expand the clinical spectrum of MOG antibody-associated presentations. An expedited diagnosis may guide the management of these complex patients.

Activity of ceftolozane/tazobactam against a collection of Pseudomonas aeruginosa isolates from bloodstream infections in Australia

Pseudomonas aeruginosa is a common pathogen causing nosocomial infection. In particular, bloodstream infection (BSI) is associated with a high rate of morbidity and mortality. Ceftolozane/tazobactam is a new β-lactam/β-lactamase antimicrobial with activity against P. aeruginosa as well as multidrug resistant (MDR) Gram negative Enterobacteriaceae. Ceftolozane/tazobactam has frequently been used in salvage therapy for MDR P. aeruginosa infections. The aim of this study was to determine the activity of ceftolozane/tazobactam against P. aeruginosa isolates from BSIs collected from three clinical microbiology laboratories in Queensland, Australia, with a high proportion of isolates demonstrating β-lactam resistance. Antimicrobial susceptibility testing was performed by broth microdilution using custom made sensititre plates sourced from ThermoFisher Scientific. In addition to ceftolozane/tazobactam, we also tested piperacillin/tazobactam, ceftazidime, cefepime, meropenem, doripenem, imipenem, aztreonam, ciprofloxacin, levofloxacin, gentamicin, amikacin, tobramycin and colistin. Overall, ceftolozane/tazobactam was the most active agent tested [(MIC_50/90 = 1/2 μg/mL, 96% susceptible (S)]. Against 44 isolates with resistance to at least one other β-lactam agent, 40 were susceptible to ceftolozane/tazobactam. Three ceftolozane/tazobactam resistant isolates were susceptible to colistin, with one of those isolates also susceptible to levofloxacin but not to any other antimicrobials tested. One ceftolozane/tazobactam resistant isolate was susceptible only to meropenem and doripenem but was non-susceptible to imipenem. An association was found between fluoroquinolone resistance and aminoglycoside resistance but not with β-lactam resistance. In summary, ceftolozane/tazobactam was active against most strains tested, including those resistant to other β-lactams. Laboratories should consider testing P. aeruginosa against ceftolozane/tazobactam in suspected MDR or extensively drug resistant (XDR) infections.

Prevalence of long-term health conditions in adults with autism: observational study of a whole country population

OBJECTIVES

To investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.

DESIGN

Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study.

SETTING

General population.

PARTICIPANTS

94% of Scotland's population, including 6649/3 746 584 adults aged 25+ reported to have autism.

MAIN OUTCOME MEASURES

Prevalence of six comorbidities: deafness or partial hearing loss, blindness or partial sight loss, intellectual disabilities, mental health conditions, physical disability and other condition; ORs (95% CI) of autism predicting these comorbidities, adjusted for age and gender; and OR for age and gender in predicting comorbidities within the population with reported autism.

RESULTS

Comorbidities were common: deafness/hearing loss-14.1%; blindness/sight loss-12.1%; intellectual disabilities-29.4%; mental health conditions-33.0%; physical disability-24.0%; other condition-34.1%. Autism statistically predicted all of the conditions: OR 3.3 (95% CI 3.1 to 3.6) for deafness or partial hearing loss, OR 8.5 (95% CI 7.9 to 9.2) for blindness or partial sight loss, OR 94.6 (95% CI 89.4 to 100.0) for intellectual disabilities, OR 8.6 (95% CI 8.2 to 9.1) for mental health conditions, OR 6.2 (95% CI 5.8 to 6.6) for physical disability and OR 2.6 (95% CI 2.5 to 2.8) for other condition. Contrary to findings within the general population, female gender predicted all conditions within the population with reported autism, including intellectual disabilities (OR=1.4).

CONCLUSIONS

Clinicians need heightened awareness of comorbidities in adults with autism to improve detection and suitable care, especially given the added complexity of assessment in this population and the fact that hearing and visual impairments may cause additional difficulties with reciprocal communication which are also a feature of autism; hence posing further challenges in assessment.

Trends and variations in per capita expenditure on adult intellectual disabilities health and social care across Scotland, and by urban/rural class

BACKGROUND

Following the global financial crisis in 2007/08, the UK implemented an austerity programme which may impact on services. Scotland comprises both densely populated urban conurbations and highly dispersed remote rural and island communities.

METHOD

Expenditure data were extracted from Scottish Government statistics. Per capita expenditure was calculated using adjusted Scotland's 2011 census data.

RESULTS

There was a 3.41% decrease in real term expenditure on adult intellectual disabilities services between 2012/13 and 2014/15 (>£32 million). In 2014/15, per capita expenditure on adult intellectual disabilities health care ranged from £1,211 to £17,595; social care from £21,147 to £83,831; and combined health and social care expenditures from £37,703 to £85,929. Per capita expenditure on combined health and social care was greater in rural areas, with more on intellectual disabilities social care, though less on health care.

CONCLUSIONS

Scottish expenditure on adult intellectual disabilities services has not kept abreast of rising living costs. It varies considerably across the country: a postcode lottery.

Prevalence of physical conditions and multimorbidity in a cohort of adults with intellectual disabilities with and without Down syndrome: cross-sectional study

OBJECTIVES

To investigate the prevalence of multimorbidity in adults with intellectual disabilities with and without Down syndrome.

DESIGN

Large, population-based cross-sectional study.

SETTING

The geographical area of one Health Board, Scotland.

PARTICIPANTS

All adults (aged 16+ years) known to general practitioners to have intellectual disabilities and adults receiving services provided or paid by intellectual disabilities health or social work services. 1023/1562 potential participants took part (65.5%); 562 (54.9%) men and 461 (45.1%) women, aged 43.9 years (16-83 years). 186 had Down syndrome and 837 did not.

MAIN OUTCOME MEASURES

The prevalence of International Statistical Classification of Diseases, 10th revision, physical health conditions and multimorbidity detected at a comprehensive health assessment.

RESULTS

The mean number of physical health conditions/participant was 11.04, and 98.7% had multimorbidity. The most prevalent conditions are painful and/or disabling and, in some cases, life threatening. The five most prevalent were visual impairment, obesity, epilepsy, constipation and ataxic/gait disorders. The pattern of multimorbidity differs from that seen in the general population and is spread across the entire adult life course. The extent of multimorbidity in the adults with Down syndrome was similar to that of the adults without Down syndrome, while the prevalence of individual conditions differed.

CONCLUSIONS

This robustly designed study with a large population found an extremely high prevalence of multimorbidity in adults with intellectual disabilities across the entire adult life course. This increases complexity of medical management that secondary healthcare services and medical education are not yet geared towards, as these tend to focus on single conditions. This is in addition to complexity due to limitations in communication and understanding. As the physical conditions within their multimorbidity also differ from that seen in the older general population, urgent attention is needed to develop the care pathways and guidelines that are required to inform and so improve their healthcare.

Prevalence and general health status of people with intellectual disabilities in Scotland: a total population study

Background

Prevalence of intellectual disabilities varies considerably between studies. People with intellectual disabilities experience health inequalities, but most studies comprise small or incomplete populations. We investigated in a whole country population the (1) prevalence of intellectual disabilities and (2) general health status compared with the general population.

Method

Data were from Scotland’s Census, 2011. We calculated the prevalence of intellectual disabilities, reported general health status of people with and without intellectual disabilities and the extent of health-related limitations to daily activities. We conducted logistic regressions to determine the ORs of intellectual disabilities predicting poor health and associations with age and gender.

Results

Of Scotland’s 5 295 403 population, 26 349 (0.5%) had intellectual disabilities; 15 149 (57.5%) were males and 11 200 (42.5%) were females; 5234 (0.6%) were children/youth (0–15) and 21 115 (0.5%) were adults (16–75+ years). Identification of intellectual disabilities rises until age 5 years, with a further small rise by age 9 years. Children and adults with intellectual disabilities reported more poor health (47.9% and 40.3%) than the general population (2.1% and 13.8%) and were more limited in activities by their health. Intellectual disabilities had an OR of 43.2 (95% CI 40.8 to 45.7) in predicting poor health; the influence of increasing age on poor health was markedly interacted by presence of intellectual disabilities, likely to be due to a ‘healthy survivor’ effect within the intellectual disabilities population.

Conclusion

People with intellectual disabilities have poorer general health than other people, especially children and young people. Accurate information on population prevalence and health status is essential to plan appropriate resources.
