RESUMEN
Objective To explore the effects of trans-theoretical model on the behaviors of foot serf-care in patients with type 2 diabetes mellitus.Methods One hundred and twenty patients with type 2 diabetes were recruited from a community in Guangzhou.The patients were randomly divided into control group (routine diabetic foot education) and experimental group (intervention based on tram-theoretical model of behavior change).Result Repeated Measures ANOVA showed that the main effects of intervention and time,as well as the interaction effect between intervention and time were all significant (P<0.05).The incidence rates of the chap of foot skin,paronychia and destruction of foot skin were significantly different between the two groups (P<0.05),while no significant difference on the incidence rate of foot ringworm was found (P>0.05).Conclusions The application of tram-theoretical model can promote the improvement of foot self-care behaviors and thereby to improve the condition of foot skin in patients with type 2 diabetes.
RESUMEN
Objective To solve the problem that the timely salvation can not be provided to the critical sick when nurses are not in nurse station and can not hear the sound of buzzer. Methods By utilizing SCM and wireless numerical transmission module, the former sick area treatment station calling system was developed. The special information was coded through SCM. The dada were sent and received with wireless numerical transmission module. In this way, a portable calling information receiving machine was designed. Results The reliable receiving distance of receiving machine is in the bound of 800 meters, and it provides 16 channels to use for different floors, having data transmission check function, little power loss, performance steady and credibility. Conclusion With sickroom calling message receiving machine, the nurse on duty can receive the calling message of the sick at any time and in any room, so rapid treatment can be provided on time, improving the satisfaction degree of sick. Besides, the sound of the calling system in the sick area treatment station can be shut down at noon and night, thus providing better circumstance for the sick to rest. The design is suitable for the calling system in any type and makes up the original shortages of the calling system in hospital.
