Photos and videos circulating on social media show Gaucho arriving at the Level 5 facility in a white van walking through the premises and engaging directly with hospital operations.
In one image he is seen examining shelves stocked with drugs labeled under GIT and DDA categories while in others he gestures during discussions near a hospital signboard and mingles with personnel and visitors.
The visit appeared focused on practical issues affecting day-to-day service delivery.
He examined drug stocks observed patient areas and held discussions that suggested a strong interest in the immediate operational realities facing one of Nairobi's busiest public health facilities serving Eastlands and the surrounding areas.
Gaucho's appointment to the board gazetted recently for a three-year term has generated considerable public debate since it was announced.
He rose to prominence as a grassroots political activist and vocal supporter of opposition figures within ODM circles building his reputation through community mobilization in Nairobi's informal settlements rather than formal administrative experience.
Critics have questioned the suitability of the appointment citing his limited formal education with reports indicating he dropped out of school in Class Six.
They argue that sensitive public health institutions require board members with qualifications and professional backgrounds that match the gravity of the responsibilities involved.
Supporters however counter that lived experience and a genuine connection to ordinary Kenyans bring a valuable perspective to oversight roles that are often dominated by elites far removed from the communities these hospitals serve every day.
Mama Lucy Kibaki Hospital named after the late former First Lady handles extremely high patient volumes daily and faces perennial challenges including medication shortages infrastructure maintenance and staffing gaps.
Gaucho's impromptu inspection has been framed by some observers as a signal that he intends to take a hands-on approach to the role from the very beginning.
The appointment has sparked wider questions about how county governments select board members for critical public institutions and whether lived experience alone is sufficient qualification for governance roles in the health sector.
Gaucho has reportedly asked for time to prove his contribution emphasizing service delivery over academic credentials.
His unannounced hospital visit suggests he is wasting no time in making that case.
