Impact of informed-choice invitations on diabetes screening knowledge, attitude and intentions: an analogue study.

ABSTRACT:

Background

Despite concerns that facilitating informed choice would decrease diabetes screening uptake, 'informed choice' invitations that increased knowledge did not affect attendance (the DICISION trial). We explored possible reasons using data from an experimental analogue study undertaken to develop the invitations. We tested a model of the impact on knowledge, attitude and intentions of a diabetes screening invitation designed to facilitate informed choices.

Methods

417 men and women aged 40-69 recruited from town centres in the UK were randomised to receive either an invitation for diabetes screening designed to facilitate informed choice or a standard type of invitation. Knowledge of the invitation, attitude towards diabetes screening, and intention to attend for diabetes screening were assessed two weeks later.

Results

Attitude was a strong predictor of screening intentions (? = .64, p = .001). Knowledge added to the model but was a weak predictor of intentions (? = .13, p = .005). However, invitation type did not predict attitudes towards screening but did predict knowledge (? = -.45, p = .001), which mediated a small effect of invitation type on intention (indirect ? = -.06, p = .017).

Conclusions

These findings may explain why information about the benefits and harms of screening did not reduce diabetes screening attendance in the DICISION trial.

Project description:BackgroundDown Syndrome screening test is a bridge between knowledge and uncertainty, safety and risk, unpredictability and desire to know in order to gain control. It may be accepted either not to have a baby with Down syndrome, or to prepare to have a baby with this condition. Every woman should understand that it is an option and should be encouraged to make their own decisions based on information and personal values. The implications and possible subsequent scenarios differentiate this type of test from the common biochemical tests performed during pregnancy, of paramount importance being the right to make informed choices. The aim of this study was to investigate the knowledge and attitude towards prenatal Down syndrome screening in order to asses to what extent the Romanian women make informed choices in this area.MethodsA cross-sectional study was carried out that included 530 postpartum women, clients of Romania' south-east region maternities, during April-September 2016. The level of knowledge and the attitude concerning the Down syndrome screening were evaluated using a questionnaire. Data were analyzed using SPSS version 20.0.Results48.1% of the women have never heard about any tests for Down Syndrome and from those 51.9% who have heard, only 14.2% made an informed choice, 78.9% had a positive attitude for screening, 88% were classified as having insufficient knowledge and 68.3% made a value-consistent decision to accept or decline prenatal screening. A higher knowledge level was associated with a higher education level and the urban residence. The information satisfaction and confidence in the overall value of screening were predictive factors of positive attitude. More informed choices were made by women monitored by an obstetrician in a private practice.ConclusionsThe prenatal screening tests for Down Syndrome were mostly unknown and the women who accepted or not to perform a test were insufficiently knowledgeable that means that the ethical concept of the informed choice wasn't followed. In our opinion the Romanian Health System needs to improve the antenatal policy by developing an adequate information strategy at the reproductive population level based on a network of trained specialists.

Project description:ObjectiveTo compare the effect of an invitation promoting informed choice for screening with a standard invitation on attendance and motivation to engage in preventive action.DesignRandomised controlled trial.SettingFour English general practices.Participants1272 people aged 40-69 years, at risk for diabetes, identified from practice registers using a validated risk score and invited to attend for screening.InterventionIntervention was a previously validated invitation to inform the decision to attend screening, presenting diabetes as a serious potential problem, and providing details of possible costs and benefits of screening and treatment in text and pie charts. This was compared with a brief, standard invitation simply describing diabetes as a serious potential problem.Main outcome measuresThe primary end point was attendance for screening. The secondary outcome measures were intention to make changes to lifestyle and satisfaction with decisions made among attenders.ResultsThe primary end point was analysed for all 1272 participants. 55.8% (353/633) of those in the informed choice group attended for screening, compared with 57.6% (368/639) in the standard invitation group (mean difference -1.8%, 95% confidence interval -7.3% to 3.6%; P=0.51). Attendance was lower among the more deprived group (most deprived third 47.5% v least deprived third 64.3%; P<0.001). Interaction between deprivation and effect of invitation type on attendance was not significant. Among attenders, intention to change behaviour was strong and unaffected by invitation type.ConclusionsProviding information to support choice did not adversely affect attendance for screening for diabetes. Those from more socially deprived groups were, however, less likely to attend, regardless of the type of invitation received. Further attention to invitation content alone is unlikely to achieve equity in uptake of preventive services.Trial registrationCurrent Controlled Trials ISRCTN 73125647.

Project description:BackgroundScreening invitations have traditionally been brief, providing information only about population benefits. Presenting information about the limited individual benefits and potential harms of screening to inform choice may reduce attendance, particularly in the more socially deprived. At the same time, amongst those who attend, it might increase motivation to change behavior to reduce risks. This trial assesses the impact on attendance and motivation to change behavior of an invitation that facilitates informed choices about participating in diabetes screening in general practice. Three hypotheses are tested: 1. Attendance at screening for diabetes is lower following an informed choice compared with a standard invitation. 2. There is an interaction between the type of invitation and social deprivation: attendance following an informed choice compared with a standard invitation is lower in those who are more rather than less socially deprived. 3. Amongst those who attend for screening, intentions to change behavior to reduce risks of complications in those subsequently diagnosed with diabetes are stronger following an informed choice invitation compared with a standard invitation.Method/design1500 people aged 40-69 years without known diabetes but at high risk are identified from four general practice registers in the east of England. 1200 participants are randomized by households to receive one of two invitations to attend for diabetes screening at their general practices. The intervention invitation is designed to facilitate informed choices, and comprises detailed information and a decision aid. A comparison invitation is based on those currently in use. Screening involves a finger-prick blood glucose test. The primary outcome is attendance for diabetes screening. The secondary outcome is intention to change health related behaviors in those attenders diagnosed with diabetes. A sample size of 1200 ensures 90% power to detect a 10% difference in attendance between arms, and in an estimated 780 attenders, 80% power to detect a 0.2 sd difference in intention between arms.DiscussionThe DICISION trial is a rigorous pragmatic denominator based clinical trial of an informed choice invitation to diabetes screening, which addresses some key limitations of previous trials.

Project description:The postponement of parenthood may increase the number of couples experiencing infertility and prolonged time to pregnancy. Previous research has revealed that childless people are not well informed regarding fertility, which may threat their childbearing intentions. This study aimed to examine fertility knowledge and childbearing intentions held by Portuguese people and their use and perceived usefulness of information sources on fertility.Participants were recruited using a random-route domiciliary approach. A total of 2404 individuals aged 18-45 were asked to complete a structured questionnaire evaluating socio-demographic characteristics, childbearing intentions, fertility knowledge and information-gathering sources regarding fertility.In total, 95.5% of the participants indicated the desire to have children in the future, and 61.7% reported that having children would contribute to life satisfaction. Most of the participants expressed the desire to have two children in the future. The discrepancy between the numbers of planned and desired children was higher in men, in participants with lower education levels, in professionally active participants and in the unemployed participants. Relationship stability seemed to be more important in influencing childbearing decisions than financial stability or family support. Participants' knowledge regarding fertility was poor. Women, the participants who were older than 25, the participants with longer education and the participants with higher income exhibited the greatest levels of knowledge of fertility, although this knowledge was only slightly enhanced in these subgroups. Also, the participants overestimated both the chances of spontaneous pregnancy and the success rates of assisted reproduction techniques. Finally, the results revealed that websites were the main information sources used by the participants and only 18.0% of the participants had previously discussed fertility issues with their doctors.Although Portuguese men and women reported the desire to have children in the future, their knowledge regarding fertility and infertility risk was poor. In addition, participants used more general sources of information, such as website, but not specialized sources, such as their doctors. There is a real need to work with general practitioners to empower them to provide adequate fertility information to every childless patient.
