The Geras Solutions Cognitive Test for Assessing Cognitive Impairment: Normative Data from a Population-Based Cohort.

BACKGROUND: There is a need for the development of accurate, accessible and efficient screening instruments, focused on early-stage detection of neurocognitive disorders. The Geras Solutions cognitive test (GSCT) has showed potential as a digital screening tool for cognitive impairment but normative data are needed. OBJECTIVE: The aim of this study was to obtain normative data for the GSCT in cognitively healthy patients, investigate the effects of gender and education on test scores as well as examine test-retest reliability. METHODS: The population in this study consisted of 144 cognitively healthy subjects (MMSE>26) all at the age of 70 who were earlier included in the Healthy Aging Initiative Study conducted in Umeå, Sweden. All patients conducted the GSCT and a subset of patients (n=32) completed the test twice in order to establish test-retest reliability. RESULTS: The mean GSCT score was 46.0 (±4.5) points. High level of education (>12 years) was associated with a high GSCT score (p = 0.02) while gender was not associated with GSCT outcomes (p = 0.5). GSCT displayed a high correlation between test and retest (r(30) = 0.8, p <0.01). CONCLUSION: This study provides valuable information regarding normative test-scores on the GSCT for cognitively healthy individuals and indicates education level as the most important predictor of test outcome. Additionally, the GSCT appears to display a good test-retest reliability further strengthening the validity of the test.

Tuition of emergency medical dispatchers in the recognition of agonal respiration increases the use of telephone assisted CPR.

OBJECTIVES: Bystanders cardiopulmonary resuscitation (CPR) increases survival in out-of-hospital cardiac arrest (OHCA). Emergency medical dispatchers (EMDs) can provide even totally inexperienced bystanders with instructions by telephone on how to resuscitate victims (T-CPR) until the emergency medical services (EMS) arrive. Agonal respiration makes it difficult for EMDs to identify cardiac arrests (CAs) which will prevent or delay initiation of T-CPR. The aim of this investigation was to study if tuition of EMDs can improve their ability to identify agonal respiration in OHCA to allow for more frequent offers of T-CPR. METHODS: An observational study was made in 2004 and subsequently, a repeat study was made in 2006. All OHCA (n=315 in 2004, n=255 in 2006) in the Stockholm region reported to the Swedish Cardiac Arrest Register were included and all corresponding EMS reports were reviewed. Emergency calls were recorded during the event. Witnessed cases of OHCA (n=76 in both 2004 and 2006) were analyzed using a structured data collection tool. RESULTS: The frequency of offered T-CPR to all bystanders of OHCA in 2004 was 47%. After special tuition on agonal respiration in OHCA it rose to 68% in 2006 (p=0.01). An even more marked rise was observed in OHCA cases with agonal respiration. In 2004 T-CPR was offered in 23% of these situations whereas the corresponding figures in 2006 had risen to 56% (p=0.006). CONCLUSIONS: Teaching EMDs to understand and recognize bystander descriptions of agonal respiration in patients with OHCA has resulted in a significant increase in offers of T-CPR in these situations.
