The impact of translated reminder letters and phone calls on mammography screening booking rates: Two randomised controlled trials.

ABSTRACT: INTRODUCTION:Participation in mammographic screening for breast cancer in Australia is approximately 54% among the general population, but screening among women from some culturally and linguistically diverse (CALD) backgrounds is lower. BreastScreen Victoria apply strategies to increase screening including reminder letters and phone calls; however, these are usually provided in English. Using intervention strategies generated from the Ophelia (OPtimise HEalth LIteracy and Access) community co-design process, translated mammography reminder letters and in-language phone calls were tested within two randomised control trials (RCTs). METHODS AND ANALYSIS:Women aged 50-75 years who were due for their 2-yearly screening mammography (for RCT#1) or were under-screened, i.e. ?27 months since last screen (for RCT#2) were randomised into intervention or control groups. RCT#1 compared sending women routine reminder letters (English only) with translated (Arabic or Italian) letters. RCT#2 compared reminder telephone calls to women in their preferred language (Arabic or Italian) to no telephone call. The primary outcome for each trial was screening booking rates within 14-days. Primary outcomes were tested using Pearson's chi-square test. Rates within language group (incidence ratio: IR) were compared using the Cochran-Mantel-Haenszel test. RESULTS:For RCT#1 (letters) 1,032 women were randomised into the intervention arm or to usual care. Uptake of screening bookings was similar between both groups, with no differences observed by language group. For RCT#2 (phone calls), 195 women were randomised to the intervention group or to usual care. Overall, 64.2% of women in the intervention arm and 6% in the control arm booked a screening appointment within 14 days (p<0.0001). The IR (95%CI) of booking was 10.1 (3.9, 26.3) times higher among Italian women, and 11.6 (2.9, 46.5) times higher among Arabic women in the intervention compared to usual care groups. DISCUSSION AND CONCLUSION:A service improvement initiative derived from community members and breast screen providers was found to be highly effective. This evidence informed the service provider, BreastScreen Victoria, who have implemented these improvements into routine practice to improve screening among CALD groups and reduce health inequalities.

Project description:ObjectiveTo assess the impact of increasing incentive size and reminder calls on the measles vaccine uptake rate.DesignRandomized controlled trial, randomized at individual level, stratified by clinic.SettingNigeria.Participants1088 caregivers with children aged nine months or older; had received at least one previous conditional cash transfer (CCT) at a program clinic, had received their Penta-3 immunization but had not yet received their measles immunization, and the caregiver had provided a phone number.InterventionNine clinics were randomized to two models; caregivers in Model 1 received a default of 2000 Nigerian Naira (NGN) for completing the measles vaccine, and those in Model 2 received by 3000 NGN. Caregivers from the respective clinics were then randomized to one of the four arms: 1) control (baseline amount of 2000 NGN or 3000 NGN), 2) baseline amount plus a reminder call, 3) baseline amount plus 1000 NGN and a reminder call, and 4) baseline amount plus 3000 NGN and a reminder call.Main outcome measureReceipt of measles vaccine as reported on a child health card.ResultsOverall, there was no clear trend that increasing the incentive amount resulted in an increase in vaccine uptake rates. In Model 1 households, an additional 1000 NGN and 3000 NGN resulted in a 6.4 percentage point (95% CI: -2.3-15, p-value = 0.15) and 11.8 percentage point (95% CI: 3.9-19.6, p-value = 0.003) increase in the probability of completing the measles vaccines, respectively. This increase, however, was only significant for the 3000 NGN increase. On the other hand, in Model 2 households, increasing the incentive by 1000 NGN and 3000 NGN increased the probability by 3.3 (95% CI: -3.8-10.4, p-value = 0.36) and 3.3 (95% CI: -3.7-10.4, p-value = 0.35) percentage points. These increases were not statistically significant. Adding reminder calls to CCTs increased the probability of completing the measles vaccine; caregivers who received reminder calls plus CCTs were 5.1 percentage points more likely to get their children vaccinated (95% CI: 0.50-9.8, p-value = 0.03) compared to those who received CCTs and did not receive a reminder call. These results were largely driven by caregivers who went to clinics in Model 1.ConclusionA combination of increasing incentive amounts and reminder calls modestly improves measles immunization rates. However, this program also shows that there is substantial regional heterogeneity in response to both incentives and calls. While one possible conclusion is that a larger incentive and phone reminders are more likely to work in higher income and higher baseline coverage settings, the study is not designed to evaluate this claim. Rather, policymakers could consider experimenting with a similar low-cost calling study as part of the design of other cash transfer programs to identify whether adding reminder phone calls could increase the impact of the program.

Project description:BACKGROUND:The NHS Health Check (NHS HC) is a cardiovascular risk assessment to prevent cardiovascular disease. Public Health England (PHE) wants to increase uptake. METHODS:We explored the impact of behaviourally informed invitation letters and pre-notification and reminder SMS on uptake of NHS HCs. Patients at 28 General Practices in the London Borough of Southwark who were eligible to receive an NHS HC between 1st November 2013 and 31st December 2014 were included. A double-blind randomised controlled trial with a mixed 2 (pre-notification SMS - yes or no) × 4 (letter - national template control, open-ended, time-limited, social norm) × 2 (reminder SMS - yes or no) factorial design was used. The open-ended letter used simplification, behavioural instruction and a personalised planning prompt for patients to record the date and time of their NHS HC. The time-limited letter was similar but stated the NHS HC was due in a named forthcoming month. The social norms letter was similar to the open-ended letter but included a descriptive social norms message and testimonials from local residents and no planning prompt. The outcome measure was attendance at an NHS HC. RESULTS:Data for 12, 244 invites were analysed. Uptake increased in almost all letter and SMS combinations compared to the control letter without SMS (Uptake 18%), with increases of up to 12 percentage points for the time-limited letter with pre-notification and reminder (Uptake 30%; Adjusted Odds Ratio AOR 1.86; 95% CI 1.45-2.83; p < 0.00); 10 percentage points for the open-ended letter with reminder (Uptake 27%; AOR 1.68; 95% CI 1.31-2.17; p < 0.00) and a 9 percentage point increase using the time-limited letter with reminder (Uptake 27%; AOR 1.61; 95% CI 1.25-2.10; p < 0.00). The reminder SMS increased uptake for all intervention letters. The pre-notification did not add to this effect. CONCLUSIONS:This large randomised controlled trial adds support to the evidence that small, low cost behaviourally informed changes to letter-based invitations can increase uptake of NHS HCs. It also provides novel evidence on the effect of SMS reminders and pre-notification on NHS HC attendance. TRIAL REGISTRATION:Retrospectively Registered (24/01/2014) ISRCTN36027094 .

Project description:BACKGROUND & AIMS:The fecal immunochemical test (FIT) is an alternative to colonoscopy and can increase overall screening for colorectal cancer (CRC). However, little is known about the frequency of and reasons for mishandled FIT samples. METHODS:We performed a prospective study, nested within a randomized controlled trial of patients, recruited from December 2015 through August 2017, who were not up to date with colorectal cancer screening (50-75 years old). The patients were randomly assigned to usual care or outreach groups that received a mailed FIT with low literacy level instructions or a reminder call, or both. We examined frequency of and reasons for mishandled FIT samples, including absence of collection date; time from collection to laboratory receipt of more than 14 days; or mishandling of stool, buffer, or cap. The outcomes were the frequency of mishandled FIT samples, effects of outreach on mishandling, and positive results from the FIT among proper and mishandled samples. RESULTS:FIT samples were returned from 1871 patients assigned to usual care and 3045 who received the low literacy level instructions and a reminder call. In total, 19.8% of samples were mishandled; most of these (93.7%) had not labeled the date of stool collection but were still processed. Of the received samples, 1.2% of were not processed because the time from patient collection to laboratory receipt was more than 14 days. Outreach was associated with a lower proportion of mishandled samples (16.5% vs 25.0% for usual care; P < .0001). The proportion of mishandled samples was lowest among patients who received the low literacy level instruction and a reminder call (12.8%, P < .0001). There was no significant difference in proportions of positive results between properly processed samples (7.5%) and improperly processed samples (6.2%) (P = .14). CONCLUSION:In a prospective study of patients who were not up to date with colorectal cancer screening, we found that almost 20% of FIT samples were mishandled, with most patients missing the stool collection date. Patient outreach was associated with a lower proportion of mishandled samples, but there was no difference in proportions of positive results between properly and improperly handled samples. Our findings indicate that routine processing of undated FIT samples is associated with similar rates of positive results. There are limited data on test characteristics for FIT samples beyond the 14 days of stool acquisition. The inclusion of low literacy level instructions with reminder calls was associated with improved patient handling of the FIT sample. ClincialTrials.gov no: NCT02613260.
