Perceptions of anonymised data use and awareness of the NHS data opt-out amongst patients, carers and healthcare staff

BACKGROUND

England operates a National Data Opt-Out (NDOO) for the secondary use of confidential health data for research and planning. We hypothesised that public awareness and support for the secondary use of health data and the NDOO would vary by participant demography and healthcare experience. We explored patient/public awareness and perceptions of secondary data use, grouping potential researchers into National Health Service (NHS), academia or commercial. We assessed awareness of the NDOO system amongst patients, carers, healthcare staff and the public. We co-developed recommendations to consider when sharing unconsented health data for research.

METHODS

A patient and public engagement program, co-created and including patient and public workshops, questionnaires and discussion groups regarding anonymised health data use.

RESULTS

There were 350 participants in total. Central concerns for health data use included unauthorised data re-use, the potential for discrimination and data sharing without patient benefit. 94% of respondents were happy for their data to be used for NHS research, 85% for academic research and 68% by health companies, but less than 50% for non-healthcare companies and opinions varied with demography and participant group. Questionnaires showed that knowledge of the NDOO was low, with 32% of all respondents, 53% of all NHS staff and 29% of all patients aware of the NDOO. Recommendations to guide unconsented secondary health data use included that health data use should benefit patients; data sharing decisions should involve patients/public. That data should remain in close proximity to health services with the principles of data minimisation applied. Further, that there should be transparency in secondary health data use, including publicly available lists of projects, summaries and benefits. Finally, organisations involved in data access decisions should participate in programmes to increase knowledge of the NDOO, to ensure public members were making informed choices about their own data.

CONCLUSION

The majority of participants in this study reported that the use of healthcare data for secondary purposes was acceptable when accessed by NHS. Academic and health-focused companies. However, awareness was limited, including of the NDOO. Further development of publicly-agreed recommendations for secondary health data use may improve both awareness and confidence in secondary health data use.

Mental ill-health in mothers of people with intellectual disabilities compared with mothers of typically developing people: a systematic review and meta-analysis

BACKGROUND

Mothers of people with intellectual disabilities (IDs) face exceptional challenges and may be more prone to experiencing mental ill-health compared with mothers of typically developing people. These mental ill-health problems may differ at different stages of the caregiving trajectory. However, there is no evidence synthesis on this topic. We aimed to systematically review evidence in this area and identify gaps in the existing literature.

METHOD

Prospero registration: CRD42018088197. Medline, Embase, CINAHL and PsycINFO databases were searched. No time limits were applied. Studies were limited to English language. Inclusion criteria were studies of mothers of people with IDs that also included a comparison group of mothers of typically developing/developed children. Data were extracted from selected studies using a structured database. Study selection and quality appraisal were double rated. Where possible, meta-analyses were performed.

RESULTS

Of the retrieved articles, 32/3089 were included, of which 10 reported on anxiety, 21 on depression and 23 on other indicators of mental ill-health. Overall, previous studies reported that mothers of people with IDs experienced poorer mental health as compared with mothers of typically developing people. Meta-analyses revealed significant findings for anxiety, depression, parenting stress, emotional burden and common mental disorders, but not for somatic symptoms. However, there was a considerable heterogeneity; hence, interpretation of results should be cautious. Identified gaps included scarce research on mental ill-health of mothers of adults with IDs at different stages of the caregiving trajectory.

CONCLUSIONS

There is evidence of poorer mental ill-health in mothers of people with IDs compared with mothers of typically developing people, but lack of focus on different stages of the caregiving trajectory, methodological inconsistencies between studies and lack of robust studies pose limitations. This highlights the need both for improved support for mothers of people with IDs and for further methodologically robust research.

The prevalence and general health status of people with intellectual disabilities and autism co-occurring together: a total population study

BACKGROUND

Little is known about the population prevalence of co-occurring intellectual disabilities and autism, and its impact on general health status. The study aimed to investigate this, in comparison with the general population.

METHOD

Whole country data from Scotland's Census, 2011, were analysed. Descriptive statistics were generated; chi-squared tests were undertaken; and logistic regressions were undertaken both with the whole general population data, adjusted for age and gender, and within the population with co-occurring intellectual disabilities and autism.

RESULTS

A total of 5709/5 295 403 (1.08/1000) people had co-occurring intellectual disabilities and autism; 2.58/1000 children/young people and 0.74/1000 adults. The peak reported prevalence was at age 10 years (3.78/1000); 66.0% were male. Their general health status was substantially poorer than for the rest of the population, more so for children/young people, and they had more limitations in their day-to-day activities. Co-occurring intellectual disabilities and autism had odds ratio = 48.8 (45.0-53.0) in statistically predicting poor health.

CONCLUSION

This is the first study to report the population prevalence of coexisting intellectual disabilities and autism, and the substantial influence this double disadvantage has on general health status, apparent across the entire life course. This highlights a group in need of wider recognition for whom resources should be focused on and planned for, informed by evidence. Staff in services for people with either of these conditions need to be trained, equipped, resourced and prepared to address the challenge of working for people with this duality. This is essential, to address these substantial health inequalities.

The National Advisory Committee on Infection Prevention and Control (NAC-IPC)

This paper describes the work of the National Advisory Committee on Infection Prevention and Control (NAC-IPC), previously Infection Prevention and Control Expert Working Group, a longstanding external advisory body that provides subject matter expertise and advice to the Public Health Agency of Canada (PHAC) on the prevention and control of infectious diseases in Canadian health care settings. Originally established by Health Canada as the Infection Control Guidelines Steering Committee in 1992, this advisory board has been providing expert advice on infection prevention and control (IPC) guideline development for over 25 years. The NAC-IPC provides advice to inform the development of comprehensive or concise guidelines, quick reference guides and interim guidelines (usually for emerging pathogens), working closely with PHAC's national Healthcare-Associated Infections (HAIs) surveillance programs for Canadian health care facilities. PHAC's HAI-IPC professionals conduct the necessary literature research, data extraction, evidence synthesis, evidence grading (where applicable) and scientific writing for the guidelines. Due to the paucity of clinical trials and high quality observational studies to inform recommendations for emerging pathogens, expert opinion is critical for interpreting available evidence. .

The organisation of critical care for burn patients in the UK: epidemiology and comparison of mortality prediction models

In the UK, a network of specialist centres has been set up to provide critical care for burn patients. However, some burn patients are admitted to general intensive care units. Little is known about the casemix of these patients and how it compares with patients in specialist burn centres. It is not known whether burn-specific or generic risk prediction models perform better when applied to patients managed in intensive care units. We examined admissions for burns in the Case Mix Programme Database from April 2010 to March 2016. The casemix, activity and outcome in general and specialist burn intensive care units were compared and the fit of two burn-specific risk prediction models (revised Baux and Belgian Outcome in Burn Injury models) and one generic model (Intensive Care National Audit and Research Centre model) were compared. Patients in burn intensive care units had more extensive injuries compared with patients in general intensive care units (median (IQR [range]) burn surface area 16 (7-32 [0-98])% vs. 8 (1-18 [0-100])%, respectively) but in-hospital mortality was similar (22.8% vs. 19.0%, respectively). The discrimination and calibration of the generic Intensive Care National Audit and Research Centre model was superior to the revised Baux and Belgian Outcome in Burn Injury burn-specific models for patients managed on both specialist burn and general intensive care units.

Metastasis-associated microRNA expression in canine uveal melanoma

BACKGROUND

Uveal melanoma (UM) is the most common primary intraocular tumour in dogs. There is no effective means of predicting whether a tumour will metastasize. microRNA (miRNA) metastasis signatures have been identified for several human cancers, including UM.

AIMS

In this study we investigated whether metastasizing and non-metastasizing canine UMs can be distinguished by miRNA expression levels.

MATERIALS AND METHODS

miRNA microarray profiling was used to compare miRNA expression in 8 metastasizing and 12 non-metastasizing formalin-fixed, paraffin-embedded (FFPE) primary UM biopsies.

RESULTS

Fourteen miRNAs exhibited statistically significant differences in expression between the metastasizing and non-metastasizing tumours. Class prediction analysis pinpointed 9 miRNAs which categorized tumours as metastasizing or non-metastasizing with an accuracy of 89%. Of the discriminating miRNAs, 8 were up-regulated in metastasizing UM, and included 3 miRNAs implicated as potential "metastasis activators" in human cutaneous melanoma. The expression of 4 of the miRNAs was subsequently measured using the quantitative reverse transcription polymerase chain reaction (RT-qPCR), and their up-regulation in metastasizing tumours validated.

CONCLUSION

miRNA expression profiles may potentially be used to identify UMs that will metastasize, and miRNAs that are up-regulated in metastasizing tumours may be targets for therapeutic intervention.

Investigation of prognostic indicators for human uveal melanoma as biomarkers of canine uveal melanoma metastasis

OBJECTIVE

To evaluate if 14 genes that discriminate metastasising and non-metastasising human uveal melanomas can differentiate metastasising and non-metastasising uveal melanomas in dogs.

METHODS

Nineteen archival biopsies of eyes with a histopathological classification of primary benign (n = 9) and malignant (n = 10) uveal melanoma were selected. Thoracic and/or abdominal metastases confirmed metastatic spread of the primary tumour in seven dogs during the follow-up period. Gene expression was assayed by Reverse Transcription-quantitative Polymerase Chain Reaction. Genes displaying statistically significant differences in expression between the metastasising and non-metastasising tumours were identified.

RESULTS

Four genes (HTR2B, FXR1, LTA4H and CDH1) demonstrated increased expression in the metastasising uveal melanomas.

CLINICAL SIGNIFICANCE

This preliminary study illustrates the potential utility of gene expression markers for predicting canine uveal melanoma metastasis. The genes displaying elevated expression in the metastasising tumours are part of a 12-discriminating gene set used in a routine assay, performed on fine needle aspirate biopsies collected without enucleation, for predicting human uveal melanoma metastasis. Further work is required to validate the results.

Identification of Sarcocystis capracanis in cerebrospinal fluid from sheep with neurological disease

Protozoal merozoites were identified in the cerebrospinal fluid of two sheep with neurological disease in the UK. Polymerase chain reaction (PCR) identified the merozoites as Sarcocystis capracanis, a common protozoal pathogen of goats. This is the first report of this species infecting sheep and may represent an aberrant infection with sheep acting as dead end hosts, or alternatively could indicate that sheep are able to act as intermediate hosts for S. capracanis, widening the previously reported host range of this pathogen. It is possible that S. capracanis is a previously unrecognised cause of ovine protozoal meningoencephalitis (OPM) in the UK.

A preliminary, qualitative exploration of the influences associated with drop-out from cognitive-behavioural therapy for problem gambling: an Australian perspective

It has been estimated that 80% of Australians engage in some form of gambling, with approximately 115,000 Australians experiencing severe problems (Productivity Commission 2010). Very few people with problem gambling seek help and, of those who do, large numbers drop-out of therapy before completing their program. To gain insights into these problems, participants who had either completed or withdrawn prematurely from an individual CBT-based problem gambling treatment program were interviewed to examine factors predictive of premature withdrawal from therapy as well as people's 'readiness' for change. The results indicated that there might be some early indicators of risk for early withdrawal. These included: gambling for pleasure or social interaction; non-compliance with homework tasks; gambling as a strategy to avoid personal issues or dysphoric mood; high levels of guilt and shame; and a lack of readiness for change. The study further showed that application of the term 'drop-out' to some clients may be an unnecessarily negative label in that a number appear to have been able to reduce their gambling urges even after a short exposure to therapy.

Understanding behavioral intent to participate in shared decision-making in medically uncertain situations

OBJECTIVE

This article describes the process undertaken to identify and validate behavioral and normative beliefs and behavioral intent based on the Theory of Reasoned Action (TRA) and applied to men between the ages of 45 and 70 in the context of their participation in shared decision-making (SDM) in medically uncertain situations. This article also discusses the preliminary results of the aforementioned processes and explores potential future uses of this information that may facilitate greater understanding, efficiency and effectiveness of clinician-patient consultations.

MATERIALS AND METHODS

Twenty-five male subjects from the Philadelphia community participated in this study. Individual semi-structure patient interviews were conducted until data saturation was reached. Based on their review of the patient interview transcripts, researchers conducted a qualitative content analysis to identify prevalent themes and, subsequently, create a category framework. Qualitative indicators were used to evaluate respondents' experiences, beliefs, and behavioral intent relative to participation in shared decision-making during medical uncertainty.

RESULTS

Based on the themes uncovered through the content analysis, a category framework was developed to facilitate understanding and increase the accuracy of predictions related to an individual's behavioral intent to participate in shared decision-making in medical uncertainty. The emerged themes included past experience with medical uncertainty, individual personality, and the relationship between the patient and his physician. The resulting three main framework categories include 1) an individual's Foundation for the concept of medical uncertainty, 2) how the individual Copes with medical uncertainty, and 3) the individual's Behavioral Intent to seek information and participate in shared decision-making during times of medically uncertain situations.

DISCUSSION

The theme of Coping (with uncertainty) emerged as a particularly critical behavior/characteristic amongst the subjects. By understanding a subject's disposition with regard to coping, researchers were better able to make connections between a subject's prior experiences, their knowledge seeking activities, and their intent to participate in SDM. Despite having information and social support, the subjects still had to cope with the idea of uncertainty before determining how to proceed with regard to shared decision-making. In addition, the coping category reinforced the importance of information seeking behaviors and preferences for shared decision-making.

CONCLUSIONS

This study applies and extends the field of behavioral and health informatics to assist medical practice and decision-making in situations of medical uncertainty. More specifically, this study led to the development of a category framework that facilitates the identification of an individual's needs and motivational factors with regard to their intent to participate in shared decision-making in situations of medical uncertainty.

Biological monitoring of smoke exposure among wildland firefighters: a pilot study comparing urinary methoxyphenols with personal exposures to carbon monoxide, particular matter, and levoglucosan

Urinary methoxyphenols (MPs) have been proposed as biomarkers of woodsmoke exposure. However, few field studies have been undertaken to evaluate the relationship between woodsmoke exposure and urinary MP concentrations. We conducted a pilot study at the US Forest Service-Savannah River Site, in which carbon monoxide (CO), levoglucosan (LG), and particulate matter (PM(2.5)) exposures were measured in wildland firefighters on prescribed burn days. Pre- and post-shift urine samples were collected from each subject, and cross-shift changes in creatinine-corrected urinary MP concentrations were calculated. Correlations between exposure measures and creatine-adjusted urinary MP concentrations were explored, and regression models were developed relating changes in urinary MP concentrations to measured exposure levels. Full-shift measurements were made on 13 firefighters over 20 work shifts in winter 2004 at the US Forest Service Savannah River site, a National Environmental Research Park. The average workshift length across the 20 measured shifts was 701+/-95 min. LG and CO exposures were significantly correlated for samples where the filter measurement captured at least 60% of the work shift (16 samples), as well as for the smaller set of full-shift exposure samples (n=9). PM(2.5) and CO exposures were not significantly correlated, and LG and PM(2.5) exposures were only significantly correlated for samples representing at least 60% of the work shift. Creatinine-corrected urinary concentrations for 20 of the 22 MPs showed cross-shift increases, with 14 of these changes showing statistical significance. Individual and summed creatinine-adjusted guaiacol urinary MPs were highly associated with CO (and, to a lesser degree, LG) exposure levels, and random-effects regression models including CO and LG exposure levels explained up to 80% of the variance in cross-shift changes in summed creatinine-adjusted guaiacol urinary MP concentrations. Although limited by the small sample size, this pilot study demonstrates that urinary MP concentrations may be effective biomarkers of occupational exposure to wood smoke among wildland firefighters.
