The COMPlaints After Stroke (COMPAS) study: protocol for a Dutch cohort study on poststroke subjective cognitive complaints.

ABSTRACT: Although many studies have assessed poststroke objective cognitive impairment, only a few have evaluated patients' subjective cognitive complaints (SCC). Although these SCC are found to be common in the early and chronic phases after stroke, knowledge about their risk factors, course over time, differences with healthy controls and their diagnostic relevance is limited. The aim of the COMPlaints After Stroke (COMPAS) study is therefore to determine the possible risk factors, prognosis, time course and predictive value of SCC in the first 2 years after stroke.A prospective cohort study is conducted in which patients are compared to non-stroke controls at 3, 6, 12 and 24 months after stroke. Approximately 300 patients are recruited from the stroke units of three hospitals in the Netherlands, while 300 controls are sought among the relatives (spouses excluded) and social networks of participants. A wide range of subjective and objective variables is assessed in both groups using interviews, questionnaires and neuropsychological assessment. The primary outcomes include SCC and objective cognitive impairment, whereas secondary outcomes are quality of life, subjective recovery and daily life functioning.The study is being carried out in agreement with the Declaration of Helsinki and the Medical Research Involving Human Subjects Act. The protocol has been approved by the medical ethics committees of the participating centres and all participants give written informed consent. The results will be published in peer-reviewed journals and disseminated to the medical society and general public.The COMPAS study is the first to systematically evaluate poststroke SCC in a prospective longitudinal design, taking a wide range of subjective and objective variables into account. The results obtained can be used to accurately inform patients and their families, as well as to develop patient-tailored intervention programmes to ultimately improve stroke patient care.

Project description:BACKGROUNDIn case of untreatable suffering at the end of life, palliative sedation may be chosen to assure comfort by reducing the patient's level of consciousness. An important question here is whether such sedated patients are completely free of pain. Because these patients cannot communicate anymore, caregivers have to rely on observation to assess the patient's comfort. Recently however, more sophisticated techniques from the neurosciences have shown that sometimes consciousness and pain are undetectable with these traditional behavioral methods. The aim of this study is to better understand how unconscious palliative sedated patients experience the last days of their life and to find out if they are really free of pain.METHODSIn this study we will observe 40 patients starting with initiation of palliative sedation until death. Assessment of comfort based on behavioral observations will be related with the results from a NeuroSense monitor, an EEG-based monitor used for evaluation of the adequacy of anesthesia and sedation in the operating room and an ECG-based Analgesia Nociception Index (ANI) monitor, which informs about comfort or discomfort condition, based on the parasympathetic tone. An innovative and challenging aspect of this study is its qualitative approach; "objective" and "subjective" data will be linked to achieve a holistic understanding of the study topic. The following data will be collected: assessment of pain/comfort by the patients themselves (if possible) by scoring a Visual Analogue Scale (VAS); brain function monitoring; monitoring of parasympathetic tone; caregivers' assessment (pain, awareness, communication); relatives' perception of the quality of the dying process; assessment by 2 trained investigators using observational scales; video and audio registration.DISCUSSIONMeasuring pain and awareness in non-communicative dying patients is both technically and ethically challenging. ANI and EEG have shown to be promising technologies to detect pain that otherwise cannot be detected with the "traditional" methods. Although these technologies have the potential to provide objective quantifiable indicators for distress and awareness in non-communicative patients, strikingly they have not yet been used to check whether the current assessments for non-communicative patients are reliable.TRIAL REGISTRATIONThe study is registered on ClinicalTrials.gov (Identifier: NCT03273244 ; registration date: 7.9.2017).

Project description:Background Subjective cognitive decline may represent at-risk persons progressing to mild cognitive impairment (MCI), which can be exacerbated by effects of anesthesia and surgery. The objective of this systematic review is to identify the most common questions in subjective cognitive complaint and informant-reported questionnaires used in assessing cognitive impairment of elderly patients that are correlated with standardized tests for cognitive impairment screening. Methods We searched Medline, PubMed, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database, Emcare Nursing, Web of Science, Scopus, CINAHL, ClinicalTrials.Gov, and ICTRP between September 20, 2005 to August 31, 2020. We included studies that evaluated subjective cognitive complaints and informant-reported questions in elderly patients. Results and conclusion A total of 28,407 patients were included from 22 studies that assessed 21 subjective complaint questionnaires and nine informant-reported questionnaires. The most common subjective cognitive complaints were those assessing anterograde memory, closely followed by perceptual-motor function and executive function. The most common informant-reported questions were those assessing executive function, temporal orientation, and anterograde memory. Questions assessing learning and memory were most associated with results from standardized tests assessing cognitive impairment. Assessing learning and memory plays a key role in evaluating subjective cognitive decline in elderly patients. Delivering subjective cognitive complaints questions to elderly patient preoperatively may aid in screening for those exhibiting cognitive signs, and in turn are at risk of postoperative complications. Thus, the results from this review contribute to knowledge for healthcare professionals regarding the use of subjective cognitive complaints and informant-reported complaints in preoperative settings.
