Effectiveness of reminder strategies on cancer screening adherence: a randomised controlled trial.

BACKGROUND: Few randomised controlled trials (RCTs) have evaluated the different recalling approaches for enhancing adherence to faecal immunochemical test (FIT)-based screening. AIM: The authors evaluated the effectiveness of two telecommunication strategies on improving adherence to yearly FIT screening. DESIGN AND SETTING: A randomised, parallel group trial was performed in a primary care screening practice. METHOD: The authors recruited 629 asymptomatic individuals aged 40-70 years with a negative FIT in 2015 to a population-based screening programme. On participation, they were invited to repeat their second round of FIT in 2016, 12 months after the first test. Each participant was randomly assigned to either interactive telephone reminder (n = 207), short message service reminder (SMS, n = 212), or control, where no additional interventions were delivered after the findings of their first FIT was communicated to the participants (n = 210). Reminders in the intervention groups were delivered 1 month before subjects' expected return. Additional telephone reminders were delivered 2 months after the expected return date to all subjects who defaulted specimen return. The outcomes included rates of FIT collection and specimen return up to 6 months after their expected return. RESULTS: At 6 months, the cumulative FIT collection rate was 95.1%, 90.4%, and 86.5%, respectively, for the telephone, SMS, and control groups (P = 0.010). The corresponding specimen return rate was 94.1%, 90.0%, and 86.0% (P = 0.022). When compared with the control, only subjects in the telephone group were significantly more likely to collect FIT tubes (adjusted odds ratio [AOR] 3.18, 95% confidence interval [CI] = 1.50 to 6.75, P = 0.003) and return completed specimens (AOR = 2.73, 95% CI = 1.35 to 5.53, P = 0.005). CONCLUSION: Interactive telephone reminders are effective at securing previously screened subjects to repeat screening 1 year after a negative finding.

Efficacy and safety of novel digital single-operator peroral cholangioscopy-guided laser lithotripsy for complicated biliary stones.

Background/study aims Laser lithotripsy can effectively fragment complicated biliary stones, but current cholangioscopes are limited by fragility, restricted mobility or moderate visual resolution. The efficacy and safety of a new digital single-operator peroral cholangioscope to guide laser lithotripsy were evaluated. Patients and methods In this prospective single-center series, consecutive patients with complicated biliary stones, defined as impacted stones > 1.5 cm in size and wider than the more distal common bile duct, or stones that failed extraction by basket mechanical lithotripsy, underwent ERCP and SpyGlass DS peroral cholangioscope (Boston Scientific, Marlborough, United States)-guided laser lithotripsy. Stone clearance rate and incidence of adverse events were determined. Results Seventeen patients (10 men, 7 women; median age 76 years) with a median biliary stone size of 2 cm underwent predominantly holmium:yttrium aluminum garnet laser lithotripsy, achieving a 94 % stone clearance rate over 1 median procedure. Lithotripsy was performed in 8 of 17 patients due to an impacted biliary stone. The remaining patients underwent lithotripsy due to prior failure of the basket mechanical lithotripter to capture or crush their stones. Post lithotripsy, 2 patients developed cholangitis and 1 patient with underlying COPD developed respiratory distress, all resolved with conservative management. There were no hemobilia, perforations, pancreatitis nor any deaths. Conclusion SpyGlass DS peroral cholangioscopy-guided laser lithotripsy is an efficient and safe modality for management of complicated biliary stones.
