Nurse-Led Mobile Phone Intervention to Promote Self-Management in Type 2 Diabetes in Ghana: A Randomized Controlled Trial.
Ernest Asante, Gillian Carter, Helen McAneney and 3 others
PMID 39588726WHAT IT FOUND
Nurse-led phone calls plus usual care did not improve blood sugar or self-management more than usual care alone.
Both groups improved, but the extra calls added no significant benefit over standard clinic visits.
Key findings
01There was no statistically significant difference in A1C reduction between the intervention and control groups.
02There were no statistically significant differences in self-management behaviors or overall self-care scores between the groups at the end of the study.

What it does not show
The trial was conducted at a single site in Ghana, limiting generalizability. Participants and interventionists could not be blinded, which may have influenced self-reported outcomes. Self-management adherence was measured by self-report, which is subject to recall bias. The study excluded patients with optimal A1C levels (<7%), so results apply only to those with suboptimal control. The 3-month follow-up period may have been too short to detect sustained changes in some secondary outcomes like lipids.
Declared interests
The study was funded by the UK National Institute for Health and Care Research (NIHR) and the Queen's University Belfast. The authors declare no conflicts of interest.
The easy way to misread this
Do not conclude that nurse-led phone interventions are ineffective for diabetes management. Both groups improved significantly, and the control group received usual care which may have been more intensive or effective than typical standard care in other settings. The null finding indicates no *added* benefit over this specific usual care, not that the intervention itself is useless.
