Despite this, depression often remains unidentified and untreated. This pilot study evaluated the feasibility, fidelity, acceptability and preliminary effects of a mobile phone counselling intervention among perinatal women living with HIV and depression in India. Forty women in their third trimester (≥28 weeks of gestation) and screening positive for depressive symptoms (Edinburgh Postnatal Depression Scale ≥13) were recruited from three government-run treatment centres in Delhi. Participants were randomized to: (a) the intervention condition, 'BEST-ma-CARE' mobile phone counselling, or (b) an attention control condition, time- and phone-matched perinatal wellness counselling. All counselling was delivered via basic mobile phones. Data were collected at baseline and follow-up at 36-40 weeks pregnancy, within 7 days of delivery and at 6 and 12 weeks postpartum. Overall, 82% of the participants completed the study, with higher retention in the intervention arm (90%). Engagement was also higher in the intervention group with 78% of antenatal and 95% of postnatal calls attended, compared to 70% and 80% in the control group. The intervention was highly acceptable; 76% reported it 'helped them a lot', compared to 69% in the control group. All participants (100%) appreciated scheduled counsellor calls. Both groups showed reductions in depressive symptoms and perceived illness severity, while internalized stigma increased only in the control group. Improvements in antiretroviral adherence, viral load and CD4 counts were stronger in the intervention group.

A virtual ward is a digitally enabled service enabling people requiring hospital-level care to receive that care at home, either as an alternative to hospital admission or by facilitating an earlier discharge. Four themes emerged from the data: (i) Readiness for change: the virtual ward service was not embedded in existing health provision with scepticism and reluctance to refer to the virtual ward. (ii) Confidence and trust: due to system incompatibility issues, clinicians lost confidence and trust in the remote monitoring system; however, patients had high levels of trust in the virtual ward staff, increasing their confidence to remain at home. (iii) Digital challenges: using the monitoring equipment was challenging for some patients with issues of digital exclusion including understanding the technology and connection difficulties. (iv) Impact: despite the challenges, the virtual ward was highly valued by patients and supports person-centred care, offering a safe alternative to hospital admission.

Significant heterogeneity in study designs, program structures and data collection methods precluded meta-analysis, leading to a narrative synthesis of the results. Fifteen studies were included, featuring a mix of quantitative and qualitative designs. Findings indicated that mHealth MBIs demonstrated promise in reducing stress, anxiety and depressive symptoms during pregnancy and postpartum. However, participant engagement in these interventions was influenced by factors such as intervention complexity, user interface challenges and technological issues like app compatibility. Dropouts were commonly attributed to time constraints and technical difficulties, while user feedback emphasized the need for varied and flexible content to sustain interest and perceived effectiveness. Overall, mHealth MBIs offer potential benefits for perinatal psychological health, particularly in reducing stress and anxiety.

Chronic diseases, like hypertension and diabetes, play a critical role in achieving UHC due to their lifelong management needs. This paper examines the implementation of a digital and mobile-based, patient-centered care model aimed at improving care for hypertensive and diabetic patients in Kenya. Between 2018 and 2019, 1626 patients from nine clinics in Nairobi, Kiambu, Nyeri and Vihiga counties were enrolled in an integrated non-communicable disease (NCD) care model including self-management devices for home monitoring, a digital health wallet (M-TIBA) for co-payment and facility-based peer support groups.

Results indicated significantly improved patient outcomes, with 50% of hypertensive and 74% of diabetic patients achieving disease control, compared to 42% and 52% at baseline. Additionally, peer group participation increased adherence to self-monitoring and lifestyle modifications, contributing to better health outcomes. Despite these successes, challenges such as accessing medications and technical issues with digital tools were identified. Financial sustainability and scalability remain critical concerns, particularly in under-resourced settings. The case study highlights the potential of digital health solutions to enhance chronic care and support UHC by improving accessibility and reducing costs. A multifaceted approach, combining digital tools with face-to-face support and addressing structural barriers in healthcare systems, is essential for long-term success.
