We reviewed mobile technology-based interventions in nursing and computed effect size of the interventions. We searched eight databases (KoreaMED, KMBASE, KISS, NDSL, Medline, EMBASE, Cochrane central library and CINAHL) using three sets of terms: mobile application, mobile app, mobile phone or smartphone; health or healthcare; and nursing. The study design, mobile technology, sample size and clinical outcomes were extracted from each study. A total of 38 studies were selected for review. Seven and six studies were used in meta-analyses for weight and fasting plasma glucose changes respectively. We found that mobile interventions used in nursing have different characteristics compared to those in other disciplines. We also found that mobile interventions in nursing led to significant improvement in weight and glucose control.
