Supporting people with type 2 diabetes in effective use of their medicine through mobile health technology integrated with clinical care (SuMMiT-D pilot): results of a feasibility randomised trial

BACKGROUND

The purpose of this 6-month intervention pilot feasibility randomised trial was to test sending brief messages using mobile phones to promote self-management through taking medication as prescribed to people with type 2 diabetes. This was to inform the design and conduct of a future large-scale United Kingdom-based clinical trial and establish the feasibility of recruitment, the technology used, follow-up, and data collection.

METHODS

A multicentre individually randomised, controlled parallel group trial in primary care, recruiting adults (≥ 35 years) with type 2 diabetes in England. Consenting participants were randomly allocated to receive short message system text messages up to four times a week, or usual care, for a period of 6 months; messages contained behavioural change techniques targeting medication use. The primary outcome was the rate of recruitment to randomisation of participants to the trial with a planned rate of 22 participants randomised per month. The study also aimed to establish the feasibility of follow-up at 6 months, with an aim of retaining more than 80% of participants. Data, including patient-reported measures, were collected at baseline and the end of the 6-month follow-up period, and a notes review was completed at 24 months.

RESULTS

The trial took place between 26 November 2018 and 30 September 2019. In total 209 participants were randomly allocated to intervention (n = 103) or usual care (n = 106). The maximum rate of monthly recruitment to the trial was 60-80 participants per month. In total, 12,734 messages were sent to participants. Of these messages, 47 were identified as having failed to be sent by the service provider. Participants sent 2,864 messages to the automated messaging system. Baseline data from medical records were available for > 90% of participants with the exception of cholesterol (78.9%). At 6 months, a further HbA1c measurement was reported for 67% of participants. In total medical record data were available at 6 months for 207 (99.0%) of participants and completed self-report data were available for 177 (84.7%) of participants.

CONCLUSION

The feasibility of a large-scale randomised evaluation of brief message intervention for people with type 2 diabetes appears to be high using this efficient design. Failure rate of sending messages is low, rapid recruitment was achieved among people with type 2 diabetes, clinical data is available on participants from routine medical records and self-report of economic measures was acceptable.

Use of the TIDieR checklist to describe an online structured education programme for type 2 diabetes

OBJECTIVES

The aim of structured education for type 2 diabetes is to improve knowledge, skills and confidence in self-management. It is recommended in the UK for everyone who is newly diagnosed with type 2 diabetes. We developed an on-line programme called HeLP-Diabetes: Starting Out to address poor uptake of face-to-face structured education. The aim of this paper is to describe the intervention in line with the Template for Intervention Description and Replication guide, which calls for better reporting of interventions.

METHODS

The Template for Intervention Description and Replication guide provided the item headings for the description. These included the theoretical underpinning, materials, procedures, providers, and mode of delivery.

RESULTS

The programme was developed to meet NICE requirements for structured education and therefore followed a structured curriculum with four sessions covering content such as what diabetes is and how it is treated, possible complications, and how lifestyle changes can improve health. Content was delivered in text, images and video, and behaviour change techniques, self-assessment and feedback were used to help people target key health behaviours. The programme was delivered entirely online, but the team were available for support via telephone. Email feedback and reminders were sent.

CONCLUSIONS

The TIDieR checklist allowed us to provide a clear structure for the description of the intervention. However, it could not capture the full complexity of the programme, and intervention developers considering using it in the future may find that it needs to be adapted to make it more specific to their intervention.

Examining the role of patients’ experiences as a resource for choice and decision-making in health care: a creative, interdisciplinary mixed-method study in digital health

Background

Traditional health information has been based on facts and figures and not on patient experience (PEx). Websites featuring people’s accounts of their experiences of health and illness are popular as a source of information, support and much else. However, there are concerns that experiential information on the internet might have adverse effects on health.

Aims

To find out whether, when and how the NHS should incorporate PEx into online health information and elucidate the mechanisms through which PEx might influence health, develop a tool to measure the effects of online PEx, explore how PEx is used, and investigate the feasibility and acceptability of a randomised controlled trial of online PEx.

Methods

Mixed methods, including a conceptual literature review, qualitative secondary data analysis, the development of a new questionnaire, online ethnography, observational and experimental studies in an internet café environment, and finally feasibility trials to compare new websites based on PEx with those based on facts and figures.

Results

The review concluded that online PEx could affect health outcomes through seven domains (information, support, affecting relationships, providing ideas on how to use health services, influencing behaviour change, learning to tell the story and visualising illness). We developed the e-Health Impact Questionnaire, which demonstrates good psychometric properties and is suitable for use across different health groups and various styles of online information. Online ethnographic studies found three types of PEx on multiple sclerosis (MS) platforms: accounts of ‘living with MS’, self-expression and creativity, and experiences of health care and treatment. Observational and laboratory-based methods included studies of how people find and use PEx to inform health choices. We developed a three-stage model (gating, the engagement loop and outcomes) which guided the development of six prototype multimedia websites featuring either experiential information (intervention) or factual information (comparator) for three exemplar health issues. We evaluated the feasibility and acceptability of a trial of the prototype PEx websites, comparing self-report and process measures with a comparator. In the three conditions we randomised 87 (smoking cessation), 148 (asthma), and 42 (caring for someone with MS) participants. At final (2-week) follow-up, retention rates were 75%, 82% and 86%, for smoking cessation, asthma and MS carers, respectively. Usage of the allocated websites was low. The median number of logins to the websites over the 2-week period was two, two and four; the median number of page views was 10, 15 and 27.5, respectively, with a median total duration on site of 9 minutes, 17 minutes and 31.5 minutes respectively. There were no reported adverse events or harms. The qualitative interviews with 30 trial participants found that the trial methods were acceptable and not burdensome and that preferences for combinations of different types of information were both idiosyncratic and dependent on timing and need.

Limitations

This programme used a pragmatic, mixed-methods approach, in which we adapted some standard approaches (e.g. realist review). The conceptual review provided a framework for the whole programme but did not draw on a single overarching theoretically informed approach. Instead, we used relevant theory and methods from the work package leads, who represented a range of disciplines.

Conclusions

Online PEx is not seen as an alternative to facts, or to care from a health professional, but is used in addition to other sources of information, support and expression. This programme of work indicates how the sharing of online PEx may benefit people, and how this can be measured. A randomised controlled trial is feasible but an allocated ‘exposure’ to a ‘dose of information’ is far from from how online experiences are shared in everyday life. Future work evaluating online health interventions which incorporate personal experiences should aim to reflect ‘natural’ use of the internet and might include online ethnography and offline interviews. Studies might explore how and why people use online sources of experience-based health information, and the effects on subsequent behaviour and health and social outcomes in different conditions. Future intervention research evaluating online health interventions should examine and explain issues of engagement and use, and seek to identify how to increase engagement.

Quantitative telemedicine ratings in Batten disease: implications for rare disease research

OBJECTIVE

To determine if remote administration of the Unified Batten Disease Rating Scale (UBDRS) Physical Impairment subscale by telemedicine is reliable and feasible across a broad range of disease severity.

METHODS

For the majority (n = 10) of subjects, the examination was performed by a nonphysician who had been trained to perform the examination but not to score the subjects. A trained rater scored the subjects via live video; a second trained rater performed a separate examination in person and scored that examination. For 3 telemedicine evaluations, examinations were performed and scored by a trained rater while a second trained rater simultaneously scored the subjects via live video. Reliability was determined by intraclass correlation coefficient (ICC).

RESULTS

Subjects (n = 13) represented a wide range of disease severity. Remote administration of the UBDRS Physical Impairment subscale had high interrater reliability across all subjects (ICC = 0.94). When only the subjects (n = 10) who had been examined by the nonphysician and scored remotely were included in the analysis, the reliability was unchanged (ICC = 0.95).

CONCLUSIONS

The UBDRS Physical Impairment subscale is reliable and feasible for remote administration. Telemedicine has the potential to be a useful tool in rare neurologic disease research and clinical assessment.

The nucleotide sequence of phenylalanine tRNA and 5S RNA from Rhodospirillum rubrum

The complete nucleotide sequence of tRNAPhe and 5S RNA from the photosynthetic bacterium Rhodospirillum rubrum has been elucidated. A combination of in vitro and in vivo labelling techniques was used. The tRNAPhe sequence is 76 nucleotides long, 7 of which are modified. The primary structure is typically prokaryotic and is most similar to the tRNAPhe of Escherichia coli and Anacystis nidulans (14 differences of 76 positions). The 5S ribosomal RNA sequence is 120 nucleotides long and again typical of other prokaryotic 5S RNAs. The invariable GAAC sequence is found starting at position 45. When aligned with other prokaryotic 5S RNA sequences, a surprising amount of nucleotide substitution is noted in the prokaryotic loop region of the R. rubrum 5S RNA. However, nucleotide complementarity is maintained reinforcing the hypothesis that this loop is an important aspect of prokaryotic 5S RNA secondary structure. The 5S and tRNAPhe are the first complete RNA sequences available from the photosynthetic bacteria.

The evolution of multi-isoacceptor tRNA families. Sequence of tRNA Leu CAA and tRNA Leu CAG from Anacystis nidulans

Two leucine tRNAs from the cyanophyte Anacystis nidulans have been isolated, and their complete nucleotide sequences have been determined by combining data from oligonucleotide fingerprints and sequencing gels. The two sequences are 87 nucleotides long, have the anticodons CAA and CAG, and differ from each other at a total of 28 positions. They have been compared to other known tRNA Leu sequences and incorporated into a phylogenetic tree comprising prokaryotic and chloroplastic tRNA Leu sequences. Mutations inferred from the tree show that some parts of the tRNA molecule are highly variable (the extra arm and the acceptor stem) while others are much more conserved (the D and T arms). The topology of the tree supports the idea that blue-green algae and chloroplasts share a common prokaryotic ancestor and show a basic divergence between XAA and XAG anticodon-containing tRNAs, suggesting that these two subfamilies result from an ancient gene duplication. Finally, comparison of this phylogenetic tree with those of other multi-isoacceptor tRNA families shows no common scheme, which may be due to independent refinement of codon-reading patterns in different tRNA families.
