In line with the United Nations sustainable Development Goals, India launched the Ayushman Bharat Programme (ABP) to strengthen health services and achieve UHC. Digital health technologies could be instrumental in improving the efficiency of ABP. Given that India is in the initial steps towards UHC and digital health deployment, synergy between health programmes and digital health policies is essential to realize the goal of UHC. This article aims to discuss the scope of digital health technologies for achieving UHC, their application, opportunities and challenges in the context of ABP in India.

Methods A sequential mixed-methods study was carried out to explore the intention to migrate among pharmacists in Kerala, India. A survey of 256 registered pharmacists and in-depth interviews with 15 pharmacists having high migration intentions were undertaken. Quantitative data were analysed employing univariate approaches and binary logistic regression. Qualitative data were analysed employing thematic analysis. Key findings About 44.5% (n = 114) of pharmacists expressed a high intention to migrate. Younger age of up to 30 years (AOR = 8.31, 95% CI = 2.24–30.82), more opportunities abroad (AOR = 4.28, 95% CI = 1.87–9.80), better salaries (AOR = 2.48, 95% CI = 1.04–5.95) and a general negative outlook towards a pharmacy career in Kerala (AOR = 2.83, 95% CI = 1.22–6.56) predicted a high level of intention to migrate among pharmacist...

Importantly, the health of those who are at the lowest strata such as those belonging to deprived social classes and women is worst hit. Considering that women face health inequities the most, the government of India launched “Rajiv Gandhi scheme for empowerment of adolescent girls” also called as “Sabala Yojana”. Objectives: The current study attempted to understand the interplay of the socio-economic determinants, in a national programme context and explain how they influence the utilization of benefits of Sabala Yojana by adolescent girls. Methodology: The study utilized a Quantitative led qualitative mixed-methods approach. Structured questionnaire was used for quantitative data collection whereas In-depth Interview guides were used for qualitative data collection.

Institutional deliveries are prioritized as one of the important means to reduce MMR and IMR. The current study aims to estimate and compare the out of pocket expenditure associated with institutional deliveries in EAG states of Bihar, Uttar Pradesh, Madhya Pradesh and Chhattisgarh in India. Methodology: The study was conducted through secondary analysis of NFHS 4 data. The study adheres to the approach of ecological study design and aims at comparing the OOPE and its variations at the state level. The data was analysed using SPSS version 20. Statistics of mean, standard deviation and 95% confidence levels for OOPE were computed and compared. Results: Uttar Pradesh had the highest OOPE with mean OOPE for institutional delivery of INR 7616.77, 95% CI (7310.26 – 7923.28), Chhattisgarh had the least OOPE with mean OOPE per institution...

Triboelectric nanogenerator (TENG) technology has been proved to be a simple and cost-effective method to harness ambient mechanical energy. The performance of the TENG device mainly depends on the careful selection of the material pair. So far, metals and polymer materials have dominated TENG technology. Recently, there have been few reports on metal–organic framework (MoF)-based TENGs. MoFs are very interesting and offer excellent chemical and thermal stability, besides their unique properties, such as tunable pore size and high surface area.
