Case Study: Leveraging digital technologies to optimize peer-led learning in Kano


Limited health worker capacity and ineffective learning environments hinder optimal service delivery across primary healthcare (PHC) facilities in Kano State, Nigeria. Conventional training approaches that are often classroom-based, didactic, costly, and infrequent lead to service disruptions at points of delivery when they do occur. To create an optimal learning environment, supportive of effectively upskilling health workers, the Clinton Health Access Initiative (CHAI) introduced peer-led learning (PLL) in 2016—a low-cost, non-disruptive capacity-building approach to close health worker knowledge and skills gaps. In 2020, Immunization Academy (IA) was integrated into PLL as an additional learning platform for routine immunization (RI).


Peer-led learning was not without limitations which undermined uptake and sustainability in the state. Lack of monitoring mechanisms and visibility into PLL sessions by local government (LGA) and state agencies was the biggest challenge, affecting sustainability and ownership of the program by the government at all levels. Without this visibility, managers were unable to provide the necessary feedback essential for continuity and success.


To address the issue, CHAI developed an electronic Short Message Service (SMS), or text message, reporting platform in April 2021 to complement the paper-based logbooks used for tracking progress of PPL sessions. The SMS reporting platform enabled the state to have real-time data on the performance of peer-led learning sessions, including the number of sessions conducted, the number of participants involved, materials used, and topics discussed, directly from the facilities. The reporting platform leveraged existing structures in the state such as the Referral Network Service (RNS)[1] and Kano Connect closed-user group [2] to ensure sustainability and feasibility. At US$0.01, there is little cost burden to facilities to send SMS-based reports via the Kano Connect platform to LGAs.

Use of the platform was not challenging as health workers were already experienced with sending reports via the routine immunization (RI) SMS platform [3] and the state RNS. LGAs also easily accepted the platform as it allowed them to give real-time feedback; if reports were sent in the wrong format, were incomplete, or showed no records of sessions, LGAs could quickly follow up. WhatsApp groups were created to enable feedback between the health workers and their supervisors. These groups also provided an unintended platform for peer-to peer-learning where health workers could ask each other questions, share pictures, and provide encouragement.

CHAI trained a state focal person to manage the reporting platform, troubleshoot issues, and present monthly reports to the PHC working groups to encourage government ownership and sustainability. The availability of this data and visibility into facility-level capacity building improved the government’s interest and acceptance of the approach, especially since it provided simple, yet practical means for performance management and continuous quality improvement. In addition, the reporting platform allowed managers to track and monitor the use of IA by health workers which was difficult prior to the intervention. It also provided visibility into the number of health workers participating in each session, enabling easy quantification of health workers trained. In addition to immunization, other PHC programs such as antenatal care (ANC), sexual reproductive and maternal health, malaria, and family planning were also integrated into the platform, making it available to all health workers in a facility, irrespective of the services they provide.


Between April 2021 and January 2022, at least 5,000 health workers participated in over 6,000 PPL sessions on the platform; the reporting rate averaged 100 percent for participating facilities. The autonomy given to health facilities to plan, conduct, and select discussion topics during the sessions encouraged ownership as evidenced by increased uptake across facilities. It also empowered facilities to align their selected topics to their context. For example, during a period of extremely hot weather in the state in 2021, more than 70 percent of the sessions discussed cold chain management as facilities likely recognized that the weather conditions threatened the potency of vaccines. Using mobile phones for PPL sessions and reporting indirectly saved the government US$44,340 [4], which was then used to directly train or orient at least 4,400 health workers. The integration of other programs and inclusion of all health workers enables knowledge transfer among health workers from different programs. For example, ANC service providers shared that they gained better insight, particularly into how vaccines are arranged in the refrigerator, and RI providers leveraged the platform as an opportunity to refresh their skills and knowledge in child and outpatient care.


Technology provides unlimited opportunities to optimize processes, especially in settings riddled with challenges such as funding and resource constraints, bureaucracies, and paper-based tools. Digitization enabled real-time monitoring of PLL and made available data for informed decisions, feedback, and action. Opportunities exist to scale up this approach across the country to strengthen capacity building for overall improvement in quality of care.
