How do people interpret information about colorectal cancer screening: observations from a think‐aloud study

Background

The English NHS Bowel Cancer Screening Programme biennially invites individuals aged 60–74 to participate in screening. The booklet, ‘Bowel Cancer Screening: The Facts'' accompanies this invitation. Its primary aim is to inform potential participants about the aims, advantages and disadvantages of colorectal cancer screening.

Objective

To provide detailed commentary on how individuals process the information contained within ‘The Facts’ booklet.

Design, setting and participants

This study comprised of 18 interviews with individuals aged 45–60 and used a ‘think‐aloud’ paradigm in which participants read aloud the booklet. Participant utterances (verbal statements made in response to researcher‐led prompts) were transcribed and analysed using a combination of content and thematic analysis.

Results

A total of 776 coded utterances were analysed (mean = 43.1 per person; range = 8–95). While overall comprehension was satisfactory, several problem areas were identified such as the use of complex unfamiliar terminology and the presentation of numerical information. Specific sections such as colonoscopy risk information evoked negative emotional responses. Participants made several suggestions for ways in which comprehension might be improved.

Conclusion

Public perceptions of the NHS Bowel Cancer Screening Programme information materials indicated that specific aspects of the booklet were difficult to process. These materials may be an appropriate target to improve public understanding of the aims, benefits and disadvantages of colorectal cancer screening. These findings will contribute to a broader NIHR‐funded project that aims to design a supplementary ‘gist‐based’ information leaflet suitable for low literacy populations.     

C-reactive protein and cardiovascular disease: Weighing the evidence

C-reactive protein (CRP) has been widely promoted as a strong, independent predictor of cardiovascular events and metabolic syndrome, both in general populations and in patients with clinical cardiovascular disease, and as a causal player in atherothrombosis. However, recent evidence shows that the association of CRP with cardiovascular events is weaker than previously thought, that it may be largely attributed to confounding by established causal risk factors, and that CRP is, therefore, probably not a clinically useful risk predictor. The lack of association of noncoding CRP gene polymorphisms (which determine different baseline CRP values) with coronary events or metabolic syndrome does not support a causal role for CRP, and most of the putatively proatherothrombotic in vitro effects claimed for CRP were caused by contaminants in commercial CRP preparations and not by CRP. Future clinical trials of specific CRP inhibitors now in development could directly test the contribution of CRP to pathogenesis of cardiovascular disease.     

Inequalities in reported cancer patient experience by socio‐demographic characteristic and cancer site: evidence from respondents to the English Cancer Patient Experience Survey

Patient experience is a critical dimension of cancer care quality. Understanding variation in experience among patients with different cancers and characteristics is an important first step for designing targeted improvement interventions. We analysed data from the 2011/2012 English Cancer Patient Experience Survey (n = 69 086) using logistic regression to explore inequalities in care experience across 64 survey questions. We additionally calculated a summary measure of variation in patient experience by cancer, and explored inequalities between patients with cancers treated by the same specialist teams. We found that younger and very old, ethnic minority patients and women consistently reported worse experiences across questions. Patients with small intestine/rarer lower gastrointestinal, multiple myeloma and hepatobiliary cancers were most likely to report negative experiences whereas patients with breast, melanoma and testicular cancer were least likely (top‐to‐bottom odds ratio = 1.91, P < 0.0001). There were also inequalities in experience among patients with cancers treated by the same specialty for five of nine services (P < 0.0001). Specifically, patients with ovarian, multiple myeloma, anal, hepatobiliary and renal cancer reported notably worse experiences than patients with other gynaecological, haematological, gastrointestinal and urological malignancies respectively. Initiatives to improve cancer patient experience across oncology services may be suitably targeted on patients at higher risk of poorer experience.     

Stress among parents of infants with neural tube defect and its associated factors

The purpose of this study was to assess the stress among parents (either the mother or the father) of infants with neural tube defects (NTDs) and its associated factors. Using Parenting Stress Index–Short Form (PSI‐SF), 100 parents of infants with NTDs were compared with 100 parents as a normative group. The total mean score for parents of infants with NTDs was 104.0 (standard deviation (SD) = 22.9) compared with 84.3 (SD = 18.9) for parents of infants without NTDs. Fifty‐three (53.5%) parents of infants with NTDs and 15% of the control group had clinically significant high total stress score. Parents of infants with NTDs had a significantly higher score of distress in all scales of PSI‐SF compared with those of infants without NTDs. Multivariate analysis found that mothers of infants with NTDs had a significantly higher average score for parental distress, parent–child dysfunctional interaction and total stress than fathers. Parents' lower education, unemployed parents and lower family income per month were significantly associated with increased parent–child dysfunctional interaction and parental distress. Parents with lower education and lower family income are in need for psychological and emotional support from health‐care professionals.     

Clinicians' views of formats of performance comparisons

Rationale, aims and objectives Comparisons of the performance of health care providers are increasingly being used. Despite one key audience being clinicians, there has been little research on the format and content of such comparisons. Our aim was to explore clinicians' comprehension and preferences of format and content in displaying provider outcomes using comparisons of patient reported outcome measures data. Method A qualitative study, based on seven meetings involving 107 clinicians (mostly consultant and junior doctors, and nurses), revealed their views on nine formats and five aspects of content. Results Key findings were the desire for data in more than one format, explicit display of comparative performance (rank order) and the need for explanations (e.g. of unfamiliar formats and of statistical uncertainty). Conclusions Several themes were identified that shaped clinicians' views. Results were sufficiently clear to permit recommendations for the form and content of standard reports for the National Health Service.     

Systematic Review and UK‐Based Study of PARK2 (parkin), PINK1, PARK7 (DJ‐1) and LRRK2 in early‐onset Parkinson's disease

Approximately 3.6% of patients with Parkinson's disease develop symptoms before age 45. Early‐onset Parkinson's disease (EOPD) patients have a higher familial recurrence risk than late‐onset patients, and 3 main recessive EOPD genes have been described. We aimed to establish the prevalence of mutations in these genes in a UK cohort and in previous studies. We screened 136 EOPD probands from a high‐ascertainment regional and community‐based prevalence study for pathogenic mutations in PARK2 (parkin), PINK1, PARK7 (DJ‐1), and exon 41 of LRRK2. We also carried out a systematic review, calculating the proportion of cases with pathogenic mutations in previously reported studies. We identified 5 patients with pathogenic PARK2, 1 patient with PINK1, and 1 with LRRK2 mutations. The rate of mutations overall was 5.1%. Mutations were more common in patients with age at onset (AAO) < 40 (9.5%), an affected first‐degree relative (6.9%), an affected sibling (28.6%), or parental consanguinity (50%). In our study EOPD mutation carriers were more likely to present with rigidity and dystonia, and 6 of 7 mutation carriers had lower limb symptoms at onset. Our systematic review included information from >5800 unique cases. Overall, the weighted mean proportion of cases with PARK2 (parkin), PINK1, and PARK7 (DJ‐1) mutations was 8.6%, 3.7%, and 0.4%, respectively. PINK1 mutations were more common in Asian subjects. The overall frequency of mutations in known EOPD genes was lower than previously estimated. Our study shows an increased likelihood of mutations in patients with lower AAO, family history, or parental consanguinity. © 2012 Movement Disorder Society.
