Evaluating digital libraries: a systematised review.

OBJECTIVE: The purpose of this study was to examine the models and methods for evaluating digital libraries. METHODS: Springer, Science Direct, ProQuest, Emerald, Wiley, LISTA, Web of Science (WOS), Scopus, Magiran (Persian), Irandoc (Persian), SID (Persian) and Noormags (Persian) databases were searched systematically based on the defined criteria. Selection criteria included full-text articles and dissertations published in English and Persian languages in 2004-2017. The final included articles (n = 64) were reviewed, selected and analysed by group discussions. RESULTS: The results of analysing 64 included articles for this systematised review specified that the evaluation of digital libraries is mostly focused on the service quality aspect, and DigiQual was the most frequently used model. Few studies have evaluated digital libraries in the health sector. The researcher developed questionnaire is the most frequently used method to evaluate digital libraries. CONCLUSION: Because there are fewer studies of digital libraries evaluation in the health sector, the specific features of health digital libraries should be addressed by librarians and health digital library designers to develop specific models.

Efficacy of Conversational Hypnosis and Propofol in Reducing Adverse Effects of Endoscopy.

BACKGROUND: As pain and nausea is usually associated with endoscopy procedure, its management is important to alleviate patients' anxious in this regard. OBJECTIVES: The present study aimed to examine the effectiveness of conversational hypnosis in reducing anxiety and endoscopy-related complications as well as its role in increasing the satisfaction of patients exposed to endoscopic procedures. PATIENTS AND METHODS: The participants of upper GI endoscopy procedure were randomly assigned to an experiment group (with conversational hypnosis intervention, n = 93) and a control group (n = 47). The participants' hemodynamic indexes (HR, blood pressure, pulse oximetry), anxiety, satisfaction level, and complications resulted from the procedure were monitored and included in the self-administered questionnaire. RESULTS: The results indicated that the participants in experiment group had a significant reduction of anxiety in the posttest. The adverse side effects such as vomiting, nausea, and hiccups in the experimental group was less than the control group, though this difference was not significant (P = 0.54). CONCLUSIONS: The results suggested that conversational hypnosis technique could reduce anxiety as well as the sedation process in invasive procedures such as endoscopy.
