Case Reports Randomized Controlled Trial
Pilot testing of mobile app-based blended learning on selected skills of cardiopulmonary resuscitation among nursing students.
Background Cardiopulmonary resuscitation (CPR) is a skill-oriented training programme required to be practised and updated periodically by every healthcare provider. Methods In an open-label randomized controlled trial, 81 fourth-year BSc Nursing students were randomized to experimental (n=41) and control (n=40) groups using a computer-generated table. The learning resource material was shared through a mobile-app with the experimental group (EG) and the control group (CG) received the internet link for retrieving the learning resource material, 4 days before a 1-day training programme. ⋯ CG, knowledge 17.78 [1.49] v. 17.70 [1.51], p=0.82; skill 29.85 [2.44] v. 30.08 [2.79], p=0.60). The post-intervention confidence in performing the skills (20.22 [2.76] v. 19.41 [3.63], p=0.331) and satisfaction with the method of dissemination of educational resource material (29.85 [2.4] v. 30.08 [2.79], p=0.73) were also comparable in both the groups. Conclusion Both mobile app-based and internet link-based learning resource material along with hands-on sessions were effective in bringing comparable improvement in knowledge, skills, self-confidence and satisfaction of students in performing the selected skills of cardiopulmonary resuscitation.

Comparing two different schedules of online learning for updated cardiopulmonary resuscitation guidelines in Covid-19 patients: A randomized study.
Background Coronavirus disease 2019 (Covid-19) is an evolving disease with newly generated evidence related to the clinical management of Covid-19 patients. We aimed to compare two online learning schedules for disseminating new cardiopulmonary resuscitation (CPR) guidelines in terms of knowledge gain and acceptability among nurses. Methods In a prospective randomized controlled study, 61 nurses trained in comprehensive cardiopulmonary life support (CCLS) were randomized to synchronous (n=31) and asynchronous learning groups (n= 30). ⋯ Results Both schedules of online learning were effective in improving the knowledge scores of the nurses (11.93 [3.26] v. 21.15 [1.90], p=0.01 and 11.71 [3.12] v. 20.32 [1.71], p=0.01). The mean acceptability scores of nurses in the asynchronous group were statistically lower than in the synchronous group (38.93 [2.50] v. 42.5 [3.08], p=0.007). Conclusion Both synchronous and asynchronous schedules of online learning were effective in disseminating updated CPR guidelines; however, nurses in the synchronous group were more satisfied with the learning schedule.

Randomized Controlled Trial
Primer of Epidemiology IV. Study designs II: Interventional or experimental designs.
In this article, we describe experimental study designs and focus on randomized controlled trials. Experimental studies are intervention studies in which the investigator tests a new treatment on a selected group of patients. ⋯ Experimental studies are similar to cohort studies except that the exposure is a deliberate change (intervention) made by the researcher in one group of participants and it overcomes confounding because the treatment is assigned randomly. Further, we discuss various types of randomization (random sequence allocation) and importance of allocation concealment and blinding for proper assessment of outcomes in randomized trials.

Randomized Controlled Trial
Yoga nidra practice shows improvement in sleep in patients with chronic insomnia: A randomized controlled trial.
Background Yoga nidra is practised by sages for sleep. The practice is simple to use and has been clearly laid out, but its role in the treatment of chronic insomnia has not been well studied. Methods In this randomized parallel-design study conducted during 2012-16, we enrolled 41 patients with chronic insomnia to receive conventional intervention of cognitive behavioural therapy for insomnia (n=20) or yoga nidra (n=21). ⋯ Salivary cortisol reduced statistically significantly after yoga nidra (p=0.041). Conclusion Improvement of N3 sleep, total wake duration and subjective sleep quality occurred following yoga nidra practice. Yoga nidra practice can be used for treatment of chronic insomnia after supervised practice sessions.

Randomized Controlled Trial
High uptake of an innovative mobile phone application among community health workers in rural India: An implementation study.
We assessed the uptake, feasibility and effectiveness of an mHealth intervention in improving the performance of village-based frontline workers, called accredited social health activists (ASHAs), to increase the coverage of maternal, newborn and child health services in rural India. ⋯ A high degree of acceptability, feasibility and effectiveness for the mHealth intervention among ASHAs was supported by its widespread use.
