Poor medication adherence is associated with poor clinical outcomes, an increase in hospitalisations and increased mortality. This is a multicentre randomised study that evaluates the effectiveness of using a manual pill organiser (MPO) and a custom-developed pill reminder app (PRA) on medication adherence, morbidity, as well as health economic outcomes among Indian elderly individuals taking multiple medications.

The primary objective of this study is to evaluate the impact of MPO and PRA alone or in combination in improving medication adherence among elderly individuals on multiple medications. The secondary objectives include the impact of interventions on the morbidity profile and health-related quality of life. The study also plans to assess the cost-effectiveness and cost-utility of improving medication adherence.

This is a community-based, open-label, factorial-design randomised controlled trial to be conducted across rural and urban populations at two geographically distinct sites in India. The study will enrol 752 elderly individuals aged 60–80 years, receiving three or more medications for at least 6 months and having access to smartphones. The participants will be randomised to receive one of the following interventions for 12 months: control group, PRA, MPO and MPO+PRA. All study groups would receive patient education about the importance of medication adherence. The study outcomes include the proportion of improvement in medication adherence (using Medication Adherence Rating System-5, 7-day point prevalence of medication non-adherence and pill count); adverse clinical outcomes; healthcare utilisation; health-related quality of life; cost-effectiveness and cost-utility outcomes.

The study protocol has been approved by institutional ethics committees at all three institutes. The study results for primary and secondary outcomes will be published in peer-reviewed journals.

To evaluate the diagnostic accuracy of CT in identifying small and large bowel obstruction and associated complications, including ischaemia and perforation, in adult patients.

Systematic review and meta-analysis reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy reporting guidelines.

Ovid MEDLINE and Embase were searched from 1946 to 20 February 2025.

The study included randomised controlled trials, cohort studies and case–control studies evaluating the diagnostic accuracy of CT for bowel obstruction in adults (aged ≥18 years). Only studies published in English were included. Conversely, case reports, editorials, conference abstracts without full data and studies focusing exclusively on paediatric populations or animal models were excluded.

Three reviewers independently extracted data on study characteristics, CT modality, diagnostic accuracy metrics (sensitivity, specificity and predictive values) and complications. Risk of bias was assessed using the QUADAS-2 tool. A random-effects meta-analysis was conducted. Heterogeneity was assessed using I² and Tau² statistics.

Sixty-five studies with 9418 patients were included. The pooled sensitivity and specificity of CT for bowel obstruction were 90% (95% CI 78 to 96; I²=56%, Tau²=0.36) and 88.8% (95% CI 78.0 to 94.8; I²=65%, Tau²=0.35), respectively. For bowel ischaemia, CT showed a pooled sensitivity of 47.0% (95% CI 32.4 to 59.9; I²=0%, Tau²=0.00) and specificity of 85.3% (95% CI 77.9 to 89.5; I²=1%, Tau²=0.45). Multidetector CT (MDCT) outperformed older modalities across all endpoints. Ischaemia was present in 22.05% of all cases, with higher rates in small bowel obstruction. Perforation and mortality rates were 3.98% and 4.40%, respectively. No significant publication bias was detected, and the certainty of evidence was graded as moderate for most diagnostic accuracy outcomes.

CT, particularly MDCT, offers high diagnostic accuracy for bowel obstruction and is a critical tool for detecting serious complications such as ischaemia and perforation. However, sensitivity for ischaemia remains modest. Standardised protocols and prospective studies are needed to enhance early identification and optimise care pathways.

Guideline-directed medical therapy (GDMT) for patients with heart failure with reduced ejection fraction (HFrEF) reduces morbidity and mortality and remains widely underused. An HFrEF polypill containing all four pillars of GDMT has been proposed as an implementation strategy to improve GDMT treatment rates and subsequent patient outcomes. We present the design and protocol for a proof-of-concept, pilot type I hybrid randomised clinical trial evaluating an HFrEF polypill compared with usual care among patients with HFrEF in Sri Lanka to evaluate short-term feasibility.

This multi-centre, open-label, pilot type I hybrid randomised clinical trial will recruit 40 adults with HFrEF from two public hospital sites in Colombo, Sri Lanka. Participants will be randomised to an HFrEF polypill (containing bisoprolol, losartan, eplerenone, and dapagliflozin in three available strengths) or usual care and followed for 4 weeks. The primary outcome is feasibility of recruitment measured by recruitment rate and adherence to study protocols measured by completion rate of study-related procedures. Other key outcomes include adherence to GDMT and assessment of serious adverse events among other exploratory outcomes.

The study has been approved by the ethics review committee at the Faculty of Medicine, University of Kelaniya (Sri Lanka), the institutional review board at Washington University in St. Louis (United States), and the National Medicines Regulatory Authority (Sri Lanka). The findings of this pilot trial will inform the design and implementation of a future large-scale type I hybrid trial to assess the efficacy and safety of an HFrEF polypill in improving clinical outcomes.
