Reflections on qualitative data analysis training for PPI partners and its implementation into practice

Service users should be involved in every part of the research process, including analysis of qualitative research data such as interviews and focus groups. To enhance their participation, confidence and contributions, training and support for both the ‘professional’ researcher and lay member of public is essential. Historically this has taken a number of forms from short 1 day training sessions through to training spread out over several months. There currently is limited guidance on the quantity and content of such training sessions for Patient and Public Involvement (PPI) Partners. This paper discusses and explores the content and delivery of qualitative analysis training held over two sessions of 3 h duration to members of a University PPI group. The training was designed by experienced qualitative researchers and PPI partners based on available literature and research expertise. Training included the theory of qualitative research methods, and practical qualitative analysis coding skills. These skills were developed through the use of ‘mock’ interviews which participants practiced coding in supportive group sessions. Their feedback on the training is provided. One of the PPI partners subsequently went onto code data with a researcher working on a funded research study, and has reflected on both the training sessions and the subsequent analysis of the data. These reflections have been supplemented by reflections of the researcher who worked alongside the PPI partner, revealing that the process challenged perspectives and helped them view data through a service users eyes. A positive working relationship was central to this

Individualised pelvic floor muscle training in women with pelvic organ prolapse: a multicentre randomised controlled trial

<br>Background: Pelvic organ prolapse is common and is strongly associated with childbirth and increasing age. Women with prolapsed are often advised to do pelvic floor muscle exercises, but supporting evidence is limited. Our aim was to establish if one-to-one individualised pelvic floor muscle training (PFMT) is effective in reducing prolapse symptoms.</br> <br>Methods: A parallel‐group multicentre randomised controlled trial (ISRCTN35911035) in female outpatients with newly-diagnosed, symptomatic stage I, II or III prolapse, comparing five PFMT appointments over 16 weeks (n=225) versus a lifestyle advice leaflet (n=222). Treatment allocation was by remote computer allocation using minimisation. Our primary endpoint was participants’ self-report of prolapsed symptoms at 12 months. Group assignment was masked from outcome assessors. We compared outcomes between trial groups in an intention-to-treat analysis. The cost of PFMT and savings on subsequent treatments were calculated to estimate cost-effectiveness.</br> <br>Findings: Compared to the control group, the intervention group reported fewer prolapse symptoms at 12 months (mean difference between groups in change score 1.52, 95% CI [0.46, 2.59], p=0.0053); reported their prolapse to be “better” more often (57.2% versus 44.7%, difference 12.6%, 95% CI [1.1%, 24.1%], p=0.0336); and had an increased but non-significant odds of having less severe stage of prolapse at their 6-month clinical examination, (OR 1.47, 95% CI [0.97, 2.27], p=0.07). The control group had a greater uptake of other prolapse treatment (49.6% versus 24.1%, difference 25.5%, 95% CI [14.5%, 36.0%], p <0.0001). Findings were robust to missing data. The net cost of the 25 intervention was £131.61 per woman and the cost per one-point reduction in the symptom score was £86.59, 95% CI [£50.81, £286.11]. </br&gt

AutonomROS: A ReconROS-based Autonomonous Driving Unit

Autonomous driving has become an important research area in recent years, and the corresponding system creates an enormous demand for computations. Heterogeneous computing platforms such as systems-on-chip that combine CPUs with reprogrammable hardware offer both computational performance and flexibility and are thus interesting targets for autonomous driving architectures. The de-facto software architecture standard in robotics, including autonomous driving systems, is ROS 2. ReconROS is a framework for creating robotics applications that extends ROS 2 with the possibility of mapping compute-intense functions to hardware. This paper presents AutonomROS, an autonomous driving unit based on the ReconROS framework. AutonomROS serves as a blueprint for a larger robotics application developed with ReconROS and demonstrates its suitability and extendability. The application integrates the ROS 2 package Navigation 2 with custom-developed software and hardware-accelerated functions for point cloud generation, obstacle detection, and lane detection. In addition, we detail a new communication middleware for shared memory communication between software and hardware functions. We evaluate AutonomROS and show the advantage of hardware acceleration and the new communication middleware for improving turnaround times, achievable frame rates, and, most importantly, reducing CPU load

Identifying Host Genetic Risk Factors in the Context of Public Health Surveillance for Invasive Pneumococcal Disease

Host genetic factors that modify risk of pneumococcal disease may help target future public health interventions to individuals at highest risk of disease. We linked data from population-based surveillance for invasive pneumococcal disease (IPD) with state-based newborn dried bloodspot repositories to identify biological samples from individuals who developed invasive pneumococcal disease. Genomic DNA was extracted from 366 case and 732 anonymous control samples. TagSNPs were selected in 34 candidate genes thought to be associated with host response to invasive pneumococcal disease, and a total of 326 variants were successfully genotyped. Among 543 European Americans (EA) (182 cases and 361 controls), and 166 African Americans (AA) (53 cases and 113 controls), common variants in surfactant protein D (SFTPD) are consistently underrepresented in IPD. SFTPD variants with the strongest association for IPD are intronic rs17886286 (allelic OR 0.45, 95% confidence interval (CI) [0.25, 0.82], with p = 0.007) in EA and 5′ flanking rs12219080 (allelic OR 0.32, 95%CI [0.13, 0.78], with p = 0.009) in AA. Variants in CD46 and IL1R1 are also associated with IPD in both EA and AA, but with effects in different directions; FAS, IL1B, IL4, IL10, IL12B, SFTPA1, SFTPB, and PTAFR variants are associated (p≤0.05) with IPD in EA or AA. We conclude that variants in SFTPD may protect against IPD in EA and AA and genetic variation in other host response pathways may also contribute to risk of IPD. While our associations are not corrected for multiple comparisons and therefore must be replicated in additional cohorts, this pilot study underscores the feasibility of integrating public health surveillance with existing, prospectively collected, newborn dried blood spot repositories to identify host genetic factors associated with infectious diseases

What are the views of adults with an intellectual disability (AWID), carers and healthcare professionals on a community falls management programme for AWID: a qualitative interview study in the UK

Objectives The aim of this study was to refine a draft of the ACTiON FALLS LD programme based on the views of adults with an intellectual disability (AWID), carers and healthcare professionals (HCPs). Design, setting and participants The semistructured interview study included HCP as well as AWID and carers supporting AWID living in the community. Community settings included sheltered living, supported living, AWID living at home with family carers or independently. The interview study explored the first draft of the ACTiON FALLS LD programme as well as the wider falls management for AWID. Interviews with AWID were developed to include a range of approaches (eg, case studies, pictures) to support inclusive participation. Individual interviews were digitally recorded and transcribed. Researcher notes were used during interviews with AWID. All data were analysed using the principles of framework analysis. Results 14 HCP, 8 carers and 13 AWID took part in the interview process. Five key themes were identified: programme components, programme design, programme approach, who would use the programme and programme delivery. Conclusions The views of AWID, HCP and carers showed the need to consider the impact of risk perception, anxiety and fear of falling in the adaption of the ACTiON FALLS programme. The programme needs to be accessible and support the inclusion of AWID in managing falls and ultimately fulfil the requirement for a proactive and educational tool by all.</p
