We investigated the relative efficacy of a different reminder in performing a time-based Prospective Memory (PM) task. The PM performance of 24 participants with amnesic Mild Cognitive Impairment (AMCI) has been compared with that of 24 healthy controls. As ongoing task, samples of the Attentive Matrices Test were used. In the PM task subjects were requested to write an “X” every three minutes during a 9 minutes period. Participants received the task consisting either in a low demand condition (checking number “5”) or in a high demand condition (checking numbers “1”, “4”, “9”). In order to be as punctual as possible, participants were asked to simultaneously write the “X” at task time expiration, using a digital clock. Time monitoring was recorded. Reminder occurring was manipulated in that participants could receive critical, accidental or completely absent reminder. As expected, high cognitive demand was negatively correlated with PM performance and time monitoring. Unexpectedly, all the participants did not benefit from the critical reminder. These findings demonstrated, from a behavioral perspective, that Working Memory (WM) and PM processes are not based on the same memory system and PM may require WM resources at high demand.展开更多

Methods: A total of 1 859 participants who had scheduled appointments in the health promotion center of our hospital from April 2007 to May 2007 were enrolled in the study and randomly assigned into 3 groups: control (no reminder) group,SMS text messaging reminder group and telephone reminder group. Attendance rates and costs of interventions were collected. Results: A total of 1848 participants were eligible for analysis. Attendance rates of control,SMS and telephone groups were 80.5%,87.5% and 88.3%,respectively. The attendance rates were significantly higher in SMS and telephone groups than that in the control group,with odds ratio 1.698,95% confidence interval 1.224 to 2.316,P=0.001 in the SMS group,and odds ratio 1.829,95% confidence interval 1.333 to 2.509,P<0.001 in the telephone group. However,there was no difference between the SMS group and the telephone group (P=0.670). The cost effectiveness analysis showed that the cost per attendance for the SMS group (0.31 Yuan) was significantly lower than that for the telephone group (0.48 Yuan). Conclusion: SMS and telephone are effective reminders for improving attendance rate at a health promotion center. SMS reminder may be more cost-effective compared with the telephone reminder.展开更多

Electronic resources may be candidates as diagnostic decision support systems to assist physicians in clinics or hospitals. A unique system has been developed by consisting of a disease knowledge database coupled with algorithms designed specifically for clinical reminders during real-time diagnostic processes. This system is currently being used as a diagnostic decision-support tool in a clinic base and its usefulness has been empirically evaluated by applying it to the case reports in the New England Journal of Medicine. Further studies are needed to prove its usefulness for reducing diagnostic errors in real clinical practice.展开更多

Clinical case conference was conducted using 10 difficult cases related to internal medicine. Two experienced and expert diagnosticians were invited to comprise a team. A physician assisted with a web-based diagnosis reminder system also participated. Two groups were allowed to propose three possibilities for each case immediately obtaining information on history, physical exam and simple tests. Total scores and the number of accurate diagnoses were greater in the computer-assisted physicianthan in the expert physician team. In conclusion, A web-based diagnosis reminder system can help physicians to well perform difficult diagnostic reasoningcompared to expert physicians.展开更多

The NBIOT has the characteristics of low power consumption, wide coverage and large number of connections, it supports the access of multiple intelligent medicine boxes in the same community[1].The set medication information is transmitted to the smart medicine box terminal through the NBIOT Internet of Things management platform, which sets the medication time and the medication dose. In order to prevent the mistake of taking medicine, the specifi ed medicine is opened by the medicine box electromagnetic lock device at the time of reaching the medication time, In order to remind the number of medications taken by the elderly during the medication, we use the voice module and the weighing module to provide services. At the same time, we installed a semiconductor refrigeration sheet in the medicine drawer of the medicine box, which can adjust the temperature of the medicine box to the set value to prevent the deterioration of the medicine. The experimental results of the medicine box showed that the smart medicine box of the old man has the characteristics of intelligence, stability, reliability and simple operation.展开更多
