Introduction: Cognitive stimulation is essential to maintain and / or improve the cognitive function of the elderly. Objectives: This study aimed to evaluate the impact of the application of a Cognitive Stimulation Program on the maintenance or improvement of the cognitive function of the elderly at the levels of orientation, memory, calculation and language. It was also intended to evaluate complementary measures of the impact of the intervention program, name- ly on the quality of life, depressive symptoms, in the eight cognitive domains, executive function, visuospatial capacity, memory, attention, concentration and working memory, language and orientation. Method: The program was performed in 14 sessions for seven weeks, with pre-and post-test measurements. The final sample consisted of seven elderly men, four men and three women aged between 68-89 years (80.29 ± 8.83 years), who responded to the following measures: Montreal Cognitive Assessment (MoCA), Quality of life (IAQdV-8), Geriatric De- pression Scale (GDS-15) and Cognitive Decline Test (6-CIT). Results: The post-test cognitive decline in relation to the pre-test decreased significantly (6_CIT), with an improvement in the cognitive function of the elderly. The improvement of some indicators of cognitive function is positively correlated with the self-perception of quality of life with negatively depressive symptomatology. Conclusions: The administration of Cognitive Stimulation Programs contributes to an im- provement of the cognitive function in the elderly and an increase in the quality of life.

Background: The prevention of catheter-related complications is nowadays an important topic of research. Flushing the catheters is considered an important clinical procedure in preventing malfunction and several complications such as phlebitis or infection. Considering the latest guidelines of the Infusion Nurses Society, the flushing involves a pre and post-drug administration, requiring different syringes (with associated overall increased times of preparation/administration of intravenous medication by nurses, also increasing the need for manipulation of the venous catheter). Methods: A multi-centre, two-arm randomised controlled trial with partially blinded outcome assessment, of 146 adult patients. After eligibility analysis and informed consent, participants will receive usual intravenous administration of drugs with subsequent flushing procedures, with the double-chamber syringe (arm A) or with the classical syringes (arm B). The outcomes assessment will be performed on a daily basis by the unblinded ward team, with the same procedures in both groups. Some main outcomes, such as phlebitis and infiltration, will also be evaluated by nurses from a blinded research team and registered once a day. Discussion: The study outlined in this protocol will provide valuable insight regarding the effectiveness and safety of this new medical device. The development of a new medical device (dual-chamber syringe, for drug and flush solution) seems to be an important step to facilitate the nurses’ adoption of good clinical practices in intravenous procedures, reducing the catheter manipulations.
