IntroductionMedication adherence for patients with chronic conditions such as gout, a debilitating form of arthritis that requires daily medication to prevent flares, is a costly problem. Existing interventions to improve medication adherence have only been moderately effective. Habit formation theory is a promising strategy to improve adherence. The cue-reward-repetition principle posits that habits are formed by repeatedly completing an activity after the same cue and having the action rewarded every time. Over time, cues become increasingly important whereas rewards become less salient because the action becomes automatic. Leveraging the cue-reward-repetition principle could improve adherence to daily gout medications.Methods and analysisThis three-arm parallel randomised controlled trial tests an adaptive intervention that leverages the repetition cue-reward principle. The trial will began recruitment in August 2021 in Boston, Massachusetts, USA. Eligible patients are adults with gout who have been prescribed a daily oral medication for gout and whose most recent uric acid is above 6 mg/dL. Participants will be randomised to one of three arms and given electronic pill bottles. In the two intervention arms, participants will select a daily activity to link to their medication-taking (cue) and a charity to which money will be donated every time they take their medication (reward). Participants in Arm 1 will receive reminder texts about their cue and their charity reward amount will be US$0.50 per day of medication taken. Arm 2 will be adaptive; participants will receive a US$0.25 per adherent-day and no reminder texts. If their adherence is <75% 6 weeks postrandomisation, their reward will increase to US$0.50 per adherent-day and they will receive reminder texts. The primary outcome is adherence to gout medications over 18 weeks.Ethics and disseminationThis trial has ethical approval in the USA. Results will be published in a publicly accessible peer-reviewed journal.Trial registration numberNCT04776161

BACKGROUND This is the first randomised controlled trial (RCT) of a mobile health intervention that combines telemonitoring and educational components for both acute coronary syndrome (ACS) and heart failure (HF) inpatients to prevent readmission. OBJECTIVE Objective: To evaluate the feasibility, efficacy and cost-effectiveness of a smartphone app-based model of care (TeleClinical Care – TCC) plus usual care in patients being discharged from hospital after an ACS or HF admission, in comparison to usual care alone. METHODS Methods: In this pilot, 2-centre RCT, a smartphone app-based model of care (TeleClinical Care – TCC) was applied at discharge. The primary endpoint was the incidence of unplanned 30-day readmissions. Secondary endpoints included all-cause readmissions, cardiac readmissions, cardiac rehabilitation completion, medication adherence, cost-effectiveness and user satisfaction. Intervention arm participants received the app and Bluetooth-enabled devices for measuring weight, blood pressure and physical activity daily, plus usual care. The devices automatically transmitted recordings to the patient’s smartphone and then subsequently to a central server. Abnormal readings were flagged by email to a monitoring team. Control participants received usual care. RESULTS Results: 164 hospital inpatients were randomised at the time of discharge (TCC n=81, control n = 83, mean age 61.5 years, 79% male, 78% admitted with ACS). There were 11 unplanned 30-day readmissions in both groups (P = .97). Over a mean follow-up of 193 days, the intervention was associated with a significant reduction in unplanned hospital readmissions (21 vs. 41 readmissions, P = 0.015), including cardiac readmissions (11 vs. 25, P = .025), and higher rates of cardiac rehabilitation completion (39% vs. 18%, P = .025) and medication adherence (75% vs. 50%, P = .002). The average usability rating of the app was 4.5/5. The intervention cost AUD $6,028 per cardiac readmission saved. When modelled in a mainstream clinical setting, however, enrolment of 237 patients was projected to have the same healthcare expenditure compared to usual care, and enrolment of 500 patients was projected to save approximately AUD $100,000. CONCLUSIONS Conclusion: TCC was feasible and safe for ACS and HF inpatients. The incidence of 30-day readmissions was similar, however long-term benefits were demonstrated including fewer total readmissions over 6 months, improved medication adherence and improved cardiac rehabilitation completion. CLINICALTRIAL The study was registered with the Australia New Zealand Clinical Trials Registry (ACTRN12618001547235).

IntroductionIncreasing numbers of children are failing to receive many recommended vaccines, which has led to significant outbreaks of vaccine-preventable diseases in the USA and worldwide. A major driver of undervaccination is parental vaccine hesitance. Prior research demonstrates that mothers are the primary decision maker for infant vaccination, and that their vaccination attitudes form primarily during pregnancy and early in their infant’s life.Methods and analysisThis manuscript describes the protocol for an ongoing three-armed randomised controlled trial done at Kaiser Permanente Colorado (KPCO). The trial aims to test the efficacy of provided tailored, individualised information via the Internet to pregnant and new mothers versus untailored information versus usual care on the timeliness of infant vaccination. The primary outcome to be assessed is vaccination status, which is a dichotomous outcome (up to date vs not) assessed at age 200 days, reflecting the time when infants should have completed the first set of vaccine provided (at age 2, 4 and 6 months). Infants with one or more age-appropriate recommended vaccines at least 30 days delayed are categorised as not up to date whereas all other infants are considered up to date. Secondary outcomes include vaccination status at age 489 days, reflecting receipt of recommended vaccines at age 12–15 months, as well as vaccination attitudes, hesitancy and intention. Vaccination data will be derived from the electronic medical record and the state immunisation registry. Other secondary outcomes will be assessed by online surveys.Ethics and disseminationThe study activities were approved by the Institutional Review Boards of the University of Colorado, KPCO and the University of Michigan. Results will be disseminated through peer-reviewed manuscripts and conference presentations.Trial registration numberNCT02665013; Pre-results.

IntroductionNon-adherence after kidney transplantation contributes to increased rejections, hospitalisations and healthcare expenditures. Although effective adherence interventions are sorely needed, increasing education and support to transplant recipients demands greater use of care providers’ time and resources in a healthcare system that is stretched. The objective of this clinical trial is to determine the effectiveness of an electronically delivered video series and adherence behaviour contract on improving medication adherence to immunosuppressant medications.Methods and analysisA multicentre, parallel arm, randomised controlled trial will be conducted with four sites across North America (Saskatoon, Calgary, Halifax, Chicago). Adult patients will be randomised (1:1) to either the intervention (ie, home-based video education +behaviour contract plus usual care) or usual care alone. De novo transplant recipients will be enrolled prior to their hospital discharge and will be provided with electronic access to the video intervention (immediately) and adherence contract (1 month post-transplant). Follow-up electronic surveys will be provided at 3 and 12 months postenrolment. The primary outcome will be adherence at 12 months post-transplant, as measured by self-report Basel Assessment of Adherence to Immunosuppressive medications and immunosuppressant levels. Secondary outcomes include the difference in knowledge score between the intervention and control in groups (measured by the Kidney Transplant Understanding Tool); differences in self-efficacy (Generalised Self-efficacy Scale), Beliefs of Medicine Questionnaire (BMQ), quality of life (Short Form-12), patient satisfaction and cost utilisation. The study aims to recruit at least 200 participants across participating sites.Ethics and disseminationEthical approval was obtained from the University of Saskatchewan Behavioural Ethics Committee (Beh 18–63), and all patients provide informed consent prior to participating. This educational intervention aims to improve information retention and self-efficacy, leading to improved medication adherence after kidney transplantation, at low cost, with little impact to existing healthcare personnel. If proven beneficial, delivery can be easily implemented into standard of care.Trial registration numberNCT03540121; Pre-results.

IntroductionAlthough there are many studies on the use of convalescent plasma (CP) for treatment of COVID-19, it is not clear (1) which groups of patients may benefit, (2) what dose of plasma to give, or (3) which antibody levels the plasma should contain. Previous phase I/II studies and literature review suggest that CP should only be given to patients with viraemia, that a daily infusion should be given until the patient becomes virus free and that the neutralising antibody titre should preferably be >1:640Methods and analysisAn open randomised controlled trial enrolling patients with COVID-19, who must be SARS-CoV-2 positive in both airway and blood samples and admitted to a study hospital. Block randomisation 2:1 is to either 200 mL CP (preferably titre ≥1/640) daily for up to 10 days (until virus negative in blood) plus standard care or standard care only (control arm). The primary endpoint is mortality by day 28 after study inclusion. Secondary endpoints include mortality by day 60 and doses of plasma needed to clear viraemia. Assuming a reduced mortality of approximately 30% by the CP therapy and 85%–88% survival in the control arm, approximately 600 participants will be enrolled to the CP therapy arm and 300 participants to the control arm.Ethics and disseminationEthical approval has been granted by the Swedish Ethical Review Authority (reference: 2020-06277). Results from this trial will be compiled in a clinical study report, disseminated via journal articles and communicated to stakeholders.Trial registration numberNCT04649879.
