Recruitment bias and characteristics of participants with severe cerebral palsy in a cross-sectional survey

Barriers and enablers to participating in regular screening programmes for women with cerebral palsy: A qualitative life course study

AIMS

To determine the barriers and enablers to regular, women-oriented screening programmes for women with cerebral palsy (CP); and to discuss the participants' suggestions for change.

DESIGN

Qualitative life course approach.

METHODS

Twenty-five life course interviews were conducted with women in 2020 who identified as having a diagnosis of CP. Interviews were conducted in person or using electronic platforms. Framework analysis was used to interpret the data.

FINDINGS

Access and utilization of regular screening programmes for women with CP across the life course are determined by multiple socioecological factors. Three themes are discussed focusing particularly on cervical and breast screening: 1. barriers, 2. enablers and 3. women's suggestions for change. Some women chose to opt out of sexual health checks for fear they would be too uncomfortable or the procedure would be too difficult. Practitioner attitudes towards disability in general, as well as the extent to which they understood the effects of CP for women, was highlighted as a barrier. Accessibility and adaptability of the environment also influenced women's uptake of screening.

CONCLUSION

Women with CP face many challenges to their sexual and reproductive healthcare. These can deter them from participating in regular women-oriented screening programmes, which puts them at higher risk of preventable diseases. Understanding the lifelong effects of CP for women, and the interaction with their reproductive health could help to reduce unmet needs and increase participation in relevant screening across the life course.

IMPACT

Knowledge of the challenges to regular screening programmes experienced by women with CP across the life course is crucial to provide appropriate preventative healthcare for women with CP across different stages of life. Elements of this knowledge could have benefits for the care of all disabled women.

Did previous involvement in research affect recruitment of young people with cerebral palsy to a longitudinal study of transitional health care?

OBJECTIVE

To assess whether being contacted about or participating in previous research and method of approaching potential participants affected recruitment to a transition study from child to adult healthcare services of young people with cerebral palsy (CP).

DESIGN AND METHODS

Young people with CP aged 14-18 years without severe intellectual impairment were identified from regional registers of CP in Northern Ireland and the North of England. χ² and Mann-Whitney U tests were used to assess differences in CP and sociodemographic characteristics between those recruited and those who refused. Logistic regression was used to assess contact about and recruitment to previous research and method of approach as predictors of recruitment, controlling for demographic and CP characteristics.

RESULTS

Of the 410 young people who were approached; 162 did not respond and of the 248 who responded, 96 (23%) were recruited. There were significant differences between those recruited and those who refused in age and number of previous studies they had participated in. Those who were older or who had previously been approached about research were more likely to be recruited to our study. However, those who had been recruited to previous studies were more likely to refuse to join our study.

CONCLUSIONS

The method of approach to potential participants did not affect recruitment. Older adolescents and those who had been approached about previous research were more likely to take part in our study, although there was evidence of research fatigue because if they had actually been recruited to the previous studies they were less likely to join our study. Recruitment of adolescents to studies remains challenging.

Pain report and musculoskeletal impairment in young people with severe forms of cerebral palsy: A population-based series

BACKGROUND

While pain is reportedly more prevalent in more functionally impaired children with cerebral palsy, information is scant in those with poor communication skills.

METHODS

Young people (4-27 years) with severe forms of cerebral palsy were recruited from a population-based register. The Child Health Questionnaire (CHQ) provided information on general health and bodily pain; the Paediatric Pain Profile (PPP) was used for participants with limited communication; and the Spinal Alignment and Range of Motion Measure (SAROMM) described musculoskeletal impairment.

RESULTS

123 young people (GMFCS IV=55 and V=68) and their families/carers participated. Fourteen percent of CHQ responses (n=123) reported severe/very severe pain in recent weeks, whilst 7% reported pain every/almost every day. CHQ pain report was significantly higher for young people in GMFCS level V and correlated significantly with both global health and musculoskeletal impairment. High levels of pain were recorded on the PPP for non-communicating children but only a weak correlation between PPP and CHQ scores was detected.

CONCLUSION

Managing pain in young people with severe musculoskeletal and cognitive impairment presents a huge challenge to carers and professionals. The PPP may represent a useful adjunct in those young people with severe communication difficulties.

Analysis of recruitment in a pragmatic observational study on C-reactive protein point-of-care testing in primary care

INTRODUCTION

Failure to recruit all eligible study patients can lead to biased results. Little is known on selective patient recruitment in studies on implementation of diagnostic devices.

OBJECTIVES

The aim of this observational study was to measure recruitment of patients in an implementation study in primary care on use of point-of-care (POC) C-reactive protein (CRP) and to evaluate recruitment bias and its impact on the study endpoint.

METHODS

In a cross-sectional observational study on POC CRP implementation and related antibiotics prescribing, we compared included patients with all eligible patients to assess the representativeness of the included subjects. Eligible patients were adults presenting with acute cough in primary care between March and September 2012. The frequency of POC CRP testing and the proportion of prescribed antibiotics were compared between recruited and non-recruited patients. As measure of bias, odds ratios (ORs) with accompanying 95% confidence intervals (CIs) for the association between CRP level (<20 mg/l or not) and antibiotic prescribing were computed.

RESULTS

Of all 1473 eligible patients 348 (24%) were recruited. In recruited patients, POC CRP tests were conducted and antibiotics prescribed more frequently as compared to non-recruited patients (81% versus 6% and 44% versus 29%, respectively). The ORs were 18.2 (95%CI: 9.6-34.3), 30.5 (95%CI: 13.2-70.3) and 3.8 (95%CI: 0.9-14.8) respectively in all eligible patients, the recruited and the non-recruited patients.

CONCLUSION

Selective recruitment resulted in an overestimation of POC CRP test use and antibiotic prescribing.

Early childhood constraint therapy for sensory/motor impairment in cerebral palsy: a randomised clinical trial protocol

INTRODUCTION

Cerebral palsy (CP) is the most common physical disability in childhood. It is a disorder resulting from sensory and motor impairments due to perinatal brain injury, with lifetime consequences that range from poor adaptive and social function to communication and emotional disturbances. Infants with CP have a fundamental disadvantage in recovering motor function: they do not receive accurate sensory feedback from their movements, leading to developmental disregard. Constraint-induced movement therapy (CIMT) is one of the few effective neurorehabilitative strategies shown to improve upper extremity motor function in adults and older children with CP, potentially overcoming developmental disregard.

METHODS AND ANALYSIS

This study is a randomised controlled trial of children 12-24 months corrected age studying the effectiveness of CIMT combined with motor and sensory-motor interventions. The study population will comprise 72 children with CP and 144 typically developing children for a total of N=216 children. All children with CP, regardless of group allocation will continue with their standard of care occupational and physical therapy throughout the study. The research material collected will be in the form of data from high-density array event-related potential scan, standardised assessment scores and motion analysis scores.

ETHICS AND DISSEMINATION

The study protocol was approved by the Institutional Review Board. The findings of the trial will be disseminated through peer-reviewed journals and scientific conferences.

TRIAL REGISTRATION NUMBER

NCT02567630.

Systematic Review of Cerebral Palsy Registries/Surveillance Groups: Relationships between Registry Characteristics and Knowledge Dissemination

The aims of this study were to provide a comprehensive summary of the body of research disseminated by Cerebral Palsy (CP) registries and surveillance programs from January 2009 through May 2014 in order to describe the influence their results have on our overall understanding of CP. Secondly, registries/surveillance programs and the work they produced were evaluated and grouped using standardized definitions and classification systems.

METHOD

A systematic review search in PubMed, CINAH and Embase for original articles published from 1 January 2009 to 20 May 2014 originating from or supported by population based CP registries and surveillance programs or population based national registries including CP were included. Articles were grouped by 2009 World CP Registry Congress aim, registry/surveillance program classification, geographical region, and the International Classification of Function, Disability and Health (ICF) domain. Registry variables were assessed using the ICF-CY classification.

RESULTS

Literature searches returned 177 articles meeting inclusion criteria. The majority (69%) of registry/surveillance program productivity was related to contributions as a Resource for CP Research. Prevention (23%) and Surveillance (22%) articles were other areas of achievement, but fewer articles were published in the areas of Planning (17%) and Raising the Profile of CP (2%). There was a range of registry/surveillance program classifications contributing to this productivity, and representation from multiple areas of the globe, although most of the articles originated in Europe, Australia, and Canada. The domains of the ICF that were primarily covered included body structures and function at the early stages of life. Encouragingly, a variety of CP registry/surveillance program initiatives included additional ICF domains of participation and environmental and personal factors.

INTERPRETATION

CP registries and surveillance programs, including novel non-traditional ones, have significantly contributed to the understanding of how CP affects individuals, families and society. Moving forward, the global CP registry/surveillance program community should continue to strive for uniformity in CP definitions, variables collected and consistency with international initiatives like the ICF so that databases can be consolidated for research use. Adaptation to new technologies can improve access, reduce cost and facilitate information transfer between registrants, researchers and registries/surveillance programs. Finally, increased efforts in documenting variables of individuals with CP into adulthood should be made in order to expand our understanding of CP across the lifespan.

Service use and family-centred care in young people with severe cerebral palsy: a population-based, cross-sectional clinical survey

PURPOSE

To assess healthcare use and family perception of family-centred care in children and young adults with severe cerebral palsy (CP) within a geographical region of the UK.

METHOD

Young people (4-27years) with severe forms of CP; Gross Motor Function Classification System levels IV and V, were recruited via an established case register. Data were collected in the participant's home using a standardised background proforma and validated questionnaires. The Measure of Processes of Care was used to assess the family's perception of family-centred care.

RESULTS

One-hundred and twenty-three children, young people and their families/guardians participated. Results showed high accessing of specialist services in childhood with a considerable decrease in young adults. Use of generalist services remained relatively constant. The reported use of formal respite services and support groups/youth clubs was relatively poor. Family-centred care was poor in the area of "providing general information" (2.8 ± 1.73) but more moderate in the areas of "providing specific information about the young person" (4.2 ± 1.94), "enabling and partnership" (4.2 ± 1.9), "co-ordinated and comprehensive care" (4.3 ± 1.95) and "respectful and supportive care" (4.7 ± 1.75).

CONCLUSIONS

The accessing of specialist services and respite care notably decreases amongst adolescents with severe forms of CP and the perception of family-centred care amongst families was fair at best. In particular, the results highlight the need for families to be provided with more general information and advice. Implications for Rehabilitation In a quest to enhance the rehabilitation process in young people with severe forms of cerebral palsy: Commissioners and service providers need to a adopt a more rationalised, needs led approach to service provision across the lifespan of people with severe forms of cerebral palsy, to include an effective and efficient transitional period. Habilitation specialists working with young adults need to continue to recognise the importance of family-centred care in managing this complex and chronic condition. Professionals working within the healthcare system must provide better communication and improve their dissemination of information to the families of children and young people with complex needs.
