Virtual health care for adult patients with intellectual and developmental disabilities: A scoping review

Background

The COVID-19 pandemic led to an abrupt shift to virtual health care for many patients, including adults with intellectual and developmental disabilities (IDD). Approaches to virtual care that are successful for people without IDD may need to be adapted for adults with IDD.

Objective

The aim of this scoping review was to examine what is known about virtual health care for adults with IDD and in particular, the impact of virtual delivery on access to care for this population.

Methods

A comprehensive search was conducted of the academic and grey literature. A two-stage screening process was conducted by two independent reviewers and a structured data extraction template was populated for each included study. Findings were analyzed thematically using Access to Care Framework domains.

Results

In total, 22 studies met inclusion criteria. The majority were published in the past three years and focused on specialized IDD services. A subset of 12 studies reported findings on access to care for adults with IDD. Participants generally reported high acceptability of virtual care, though some preferred face-to-face encounters. Initial results on effectiveness were positive, though limited by small sample sizes. Challenges included internet quality and technical skill or comfort.

Conclusions

This review suggests that it is possible to deliver accessible, high quality virtual care for adults with IDD, however, relatively little research has been conducted on this topic. Due to COVID-19 there is currently a unique opportunity and urgency to learn when and for whom virtual care can be successful and how it can be supported.

Examining the effectiveness of telemonitoring with routinely acquired blood pressure data in primary care: challenges in the statistical analysis

Background

Scale-up BP was a quasi-experimental implementation study, following a successful randomised controlled trial of the roll-out of telemonitoring in primary care across Lothian, Scotland. Our primary objective was to assess the effect of telemonitoring on blood pressure (BP) control using routinely collected data. Telemonitored systolic and diastolic BP were compared with surgery BP measurements from patients not using telemonitoring (comparator patients). The statistical analysis and interpretation of findings was challenging due to the broad range of biases potentially influencing the results, including differences in the frequency of readings, ‘white coat effect’, end digit preference, and missing data.

Methods

Four different statistical methods were employed in order to minimise the impact of these biases on the comparison between telemonitoring and comparator groups. These methods were “standardisation with stratification”, “standardisation with matching”, “regression adjustment for propensity score” and “random coefficient modelling”. The first three methods standardised the groups so that all participants provided exactly two measurements at baseline and 6–12 months follow-up prior to analysis. The fourth analysis used linear mixed modelling based on all available data.

Results

The standardisation with stratification analysis showed a significantly lower systolic BP in telemonitoring patients at 6–12 months follow-up (-4.06, 95% CI -6.30 to -1.82, p < 0.001) for patients with systolic BP below 135 at baseline. For the standardisation with matching and regression adjustment for propensity score analyses, systolic BP was significantly lower overall (− 5.96, 95% CI -8.36 to − 3.55 , p < 0.001) and (− 3.73, 95% CI− 5.34 to − 2.13, p < 0.001) respectively, even after assuming that − 5 of the difference was due to ‘white coat effect’. For the random coefficient modelling, the improvement in systolic BP was estimated to be -3.37 (95% CI -5.41 to -1.33 , p < 0.001) after 1 year.

Conclusions

The four analyses provide additional evidence for the effectiveness of telemonitoring in controlling BP in routine primary care. The random coefficient analysis is particularly recommended due to its ability to utilise all available data. However, adjusting for the complex array of biases was difficult. Researchers should appreciate the potential for bias in implementation studies and seek to acquire a detailed understanding of the study context in order to design appropriate analytical approaches.
