Studies assessing premature mortality in people with severe mental illness (SMI) are usually based one setting, hospital (secondary care inpatients and/or outpatients) or community (primary care). This may lead to ascertainment bias. study aimed estimate standardised ratios (SMRs) for all-cause and cause-specific SMI drawn from linked primary secondary populations compared the general population. SMRs were calculated using indirect method a United Kingdom population of almost four million...
Objective. Although interest in using electroencephalogram (EEG) activity for subject identification has grown recent years, the state of art still lacks a comprehensive exploration discriminant information within it. This work aims to fill this gap, and particular, it focuses on time-frequency representation EEG. Approach. We executed qualitative quantitative analyses six publicly available data sets following sequential experimentation approach. approach was divided three blocks analysing...
Background Longitudinal studies of patterns healthcare contacts in those who die by suicide to identify at risk are scarce. Aims To examine type and timing suicide. Method A population-based electronic case–control study all died Wales, 2001–2017, linking individuals’ records from general practices, emergency departments hospitals. We used conditional logistic regression calculate odds ratios, adjusted for deprivation. performed a retrospective continuous longitudinal analysis comparing...
Each year, approximately 800,000 people die by suicide worldwide, accounting for 1-2 in every 100 deaths. It is always a tragic event with huge impact on family, friends, the community and health professionals. Unfortunately, prevention development of risk assessment tools have been hindered complexity underlying mechanisms dynamic nature person's motivation intent. Many those who had contact services preceding year but identifying most at remains challenge.To explore feasibility using...
Background Secondary use of routinely collected health care data has great potential benefits in epidemiological studies primarily due to the large scale preexisting data. Objective This study aimed engage respondents with and without a history self-harm, gain insight into their views on for research, determine whether there were any differences opinions between 2 groups. Methods We examined young people’s mental research through web-based survey, evaluating those self-harm. Results A total...
<h3>Importance</h3> People with epilepsy are at increased risk of mortality, but, to date, the cause-specific risks all unnatural causes have not been reported. <h3>Objective</h3> To estimate mortality in people and identify medication types involved poisoning deaths. <h3>Design, Setting, Participants</h3> This population-based cohort study used 2 electronic primary care data sets linked hospitalization records, Clinical Practice Research Datalink (CPRD) England (from January 1, 1998, March...
We investigated whether associations between area deprivation, urbanicity and elevated risk of severe mental illnesses (SMIs, including schizophrenia bipolar disorder) is accounted for by social drift or causation. extracted primary secondary care electronic health records from 2004 to 2015 a population 3.9 million. identified prevalent incident individuals with SMIs their level deprivation using the Welsh Index Multiple Deprivation (WIMD) urban/rural indicator. The presence was determined...
Estimates place the prevalence of autism spectrum disorders (autism) at around 1% in population. New services for adult diagnosis have been set up Wales, UK, a time rising awareness experiences; however, no studies examined Wales. In this study, we used an anonymised e-cohort comprised healthcare record data to produce all-age estimates and incidence recorded years 2001–2016. We found overall rate records was 0.51%. The number new-recorded cases increased from 0.188 per 1000 person-years...
Introduction Reduced rates of help seeking by those who self-harmed during the COVID-19 pandemic have been reported. Objectives To understand changes in healthcare service contacts for self-harm across primary, emergency and secondary care. Methods This retrospective cohort study used routine electronic data Wales, United Kingdom, from 2016 to March 14, 2021. Population-based primary care, departments hospital admissions were linked at individual-level. All Welsh residents aged ≥10 years...
Abstract Introduction Although the evidence base on bullying victimization and self‐harm in young people has been growing, most studies were cross‐sectional, relied self‐reported non‐validated measures of self‐harm, did not separate effects in‐person cyberbullying. This study aimed to assess associations following at school cyberbullying controlling for covariates. Methods School survey data from 11 16 years pupils collected 2017 39 Welsh secondary schools linked routinely data. Inverse...
Abstract Objective To enable reproducible research at scale by creating a platform that enables health data users to find, access, curate, and re-use electronic record phenotyping algorithms. Materials Methods We undertook structured approach identifying requirements for phenotype algorithm engaging with key stakeholders. User experience analysis was used inform the design, which we implemented as web application featuring novel metadata standard defining algorithms, access via Application...
Co-occurring psychiatric disorders are common in autism, with previous studies suggesting 54-94% of autistic individuals develop a mental health condition their lifetime. Most have looked at clinically-recruited cohorts, or paediatric cohorts followed into adulthood, less known about the community population level. We therefore studied prevalence co-occurring and neurological conditions national sample.This retrospective case-control study utilised SAIL Databank to examine anonymised whole...
Genetic and neurophysiological studies of electroencephalogram (EEG) have shown that an individual's brain activity during a given cognitive task is, to some extent, determined by their genes. In fact, the field biometrics has successfully used this property build systems capable identifying users from neural activity. These always been carried out in isolated conditions, such as relaxing with eyes closed, visual targets or solving mathematical operations. Here we show for first time...
Linking survey data to administrative records requires informed participant consent. When linkage includes child data, this parental and Little is known of the potential impacts introducing consent on response rates biases in school-based surveys. This paper assessed: i) impact overall sample representativeness when for was introduced ii) quality identifiable provided facilitate linkage. Including an option piloted a sub-sample schools participating Student Health Wellbeing survey, national...
Background People under the care of mental health services are at increased risk suicide. Existing studies small in scale and lack comparisons. Aims To identify opportunities for suicide prevention underpinning data enhancement people with recent contact services. Method This population-based study includes who died by year following a Wales, 2001–2015 (cases), paired similar patients did not die (controls). We linked National Confidential Inquiry into Suicide Safety Mental Health...
Background Concern that self-harm and mental health conditions are increasing in university students may reflect widening access to higher education, existing population trends and/or stressors associated with this setting. Aims To compare population-level data on self-harm, neurodevelopmental between non-students similar characteristics before during enrolment. Method This cohort study linked electronic records from the Higher Education Statistics Agency for 2012–2018 primary secondary...
