The Core Outcome Measures for Improving Dementia Care (COM-IC) project aims to develop a core outcome set for measuring the quality of care provided to people living with dementia in routine care settings. In a previous stage of the project, 17 core outcomes were identified. This study is the next step, aiming to review the literature to identify existing or recommended, validated scales for measuring the identified core outcomes.

A rapid review

Six electronic databases (PubMed, Embase (Elsevier), CINAHL Complete (EBSCOhost), APA PsycINFO (EBSCOhost), Web of Science (Clarivate) and Scopus (Elsevier) were searched. Searches were completed on 12 July 2024.

Peer-reviewed systematic reviews or original validation studies of scales measuring dignity; engagement in advance care planning; pain; quality of life; feeling safe and secure; emotional well-being; diagnosis of dementia; behavioural and psychological symptoms of dementia; the importance of relationships; meaningful activities; hygiene and comfort; resource utilisation and safety incidents for people living with dementia were included. Peer-reviewed systematic reviews or original validation studies of the scales to measure informal carers’ quality of life, their educational opportunities, formal carers’ morale and dementia-specific qualifications were also included. All studies were required to have been conducted among people living with dementia or carers, as appropriate, and to have full texts available in English.

Data on the scale’s name, the number of subscales, subscales’ names, the number of items, response options, scoring, estimated time to complete the scale, recommended frequency of data collection and the setting where the scale was first validated were extracted. Findings are presented in figures, tables and narrative texts.

A total of 88 validated scales were identified. No scales measuring dignity, engagement in advance care planning, feeling safe and secure, hygiene or safety incidents were validated for people living with dementia. No scale was identified to measure the importance of relationships for people living with dementia, the formal carers’ dementia-specific qualifications or the educational opportunities for informal carers. The review also describes the 50 recommended or validated scales.

Several validated or recommended scales exist to measure core outcomes identified as important for assessing the quality of care provided to people living with dementia in routine care settings. This review offers COM-IC stakeholders and other potential users with information on the validated/recommended scales to measure these core outcomes.

Patients with stage III non-small cell lung cancer (NSCLC) are at high risk of developing post-treatment recurrences (50–78%) during follow-up. As more effective treatments are now available, especially for patients with oligometastatic disease, earlier detection of recurrences may prolong survival and health-related quality of life (HRQOL). With the use of 2'-deoxy-2'-[¹⁸F]fluoroglucose positron emission tomography/CT ([¹⁸F]FDG PET/CT) during follow-up, recurrences may be detected earlier. Therefore, the primary objective of this study is to compare the 3-year overall survival of patients with stage III NSCLC during follow-up surveillance with [¹⁸F]FDG PET/CT versus follow-up with conventional CT (usual care). Secondary objectives address the number, location and timing of recurrences, as well as HRQOL, cost-effectiveness and patient experiences of PET/CT scans.

In this multicentre randomised controlled clinical trial, 690 patients with stage III NSCLC (8th edition International Association for the Study of Lung Cancer (IASLC) Tumor, Nodes, Metastasis (TNM) classification) who completed curative intended treatment and started follow-up care (which may include adjuvant therapy) will be randomised 1:1 to either the intervention ([¹⁸F]FDG PET/CT) or the control group (CT). Patients will undergo follow-up scans during visits at 6, 12, 18, 24 and 36 months. Data will be collected using validated questionnaires, electronic case report forms and data extractions from the electronic health records. Additionally, blood samples will be collected, and interviews will be conducted.

The study protocol has been approved by the Medical Ethical Committee of the Radboudumc and review boards of all participating centres. Written informed consent will be obtained from all participants. Study results will be published in international peer-reviewed scientific journals and presented at relevant scientific conferences. Data will be published in a data repository or other online data archive.
