Telemedicine for Memory Service Assessments, a Literature Review

AIMS: Memory clinic waiting times are at a record high, increasing from 13 weeks in 2019 to 17.7 weeks in 2022. This backlog is partially due to COVID-19 disruption. Staff are concerned that waiting times are resulting in missed diagnoses, particularly with early-onset memory loss, and that relatives of patients with challenging behaviours are not receiving adequate support. At the start of the pandemic, many Memory Service Assessments (MSAs) were done via teleconsultation to ensure patients could access services despite lockdowns. Telemedicine has continued to be used for MSAs and is a strategy proposed to tackle waiting times. This literature review explores whether using telemedicine for MSAs is evidence-based. METHODS: A search using the MEDLINE database was conducted, using the terms ‘dementia’, plus ‘telemedicine’, ‘video calls’, and ‘telephone calls’. This identified one relevant systematic review and one clinical trial. The identified evidence was insufficient for a systematic review. A google search carried out with the same terms, identified a variety of non-academic papers: NHS Audits, Quality Improvement Projects, Clinical Network publications, and one governmental publication. RESULTS: Telemedicine was reported to reduce waiting lists. Appointments could be organised quickly, without infection risk, and without requiring transportation. At-home telemedicine consultations were relaxing for some patients and reduced demand for home visits. However, clinicians reported that some environments were cluttered and noisy, impacting the MSA. Patients struggled with the complex telemedicine technology; carers were required to facilitate the calls, which increased the risk of an inaccurate assessment. Patients with sensory impairments disliked telemedicine, and clinicians struggled to distinguish between cognitive impairment and poor hearing. Financial inequalities at times prevented telemedicine. Some relatives felt that patients would mask their memory symptoms in teleconsultations, and not speak openly about their concerns. Clinicians felt adequate safeguarding assessments were not possible over teleconsultation. There was no inclusion of the long-term impact of these assessments. No distinction was made between dementia subtypes. CONCLUSION: The National Audit of Dementia, RCPsych 2021, encourages the future use of telemedicine for MSAs. However, there is limited evidence to support its use. Telemedicine was essential during COVID-19 and may help reduce waiting times, but may also produce worse outcomes than face-to-face consultations. Only pilot studies without randomisation exist on the topic and none of these are UK based. Further research is required to produce NHS-specific data on the impact telemedicine has on: the quality of MSAs, the patients’, carers’, and clinicians’ experiences, and memory service waiting times.
