BACKGROUND – NON-COMMUNICABLE DISEASES
Non-communicable diseases (NCD) were declared a neglected global health issue by WHO in 2005
Globally, the burden of NCD is increasing yearly NCD health care needs remain unmet, especially in
resource-constrained settings such as Kibera:
need for well defined integrated models of primary care
lack of access to services
lack of adequately trained staff & NCD guidelines
medications remain expensive
follow up is a major challenge

BACKGROUND: MSF Context
The Kibera slum in Nairobi, Kenya, is characterized by poverty, poor sanitation, and a highly mobile population
Such populations are vulnerable for NCD's, such as hypertension (HTN) and diabetes mellitus (DM), inaddition to HIV

BACKGROUND: NEW FOR MSF
In 2010, MSF integrated NCD care with the existing HIV programme in three primary health care clinics in the Kibera slum
![Page 6: Integration of HIV and Non-communicable Disease management into Primary Care in Nairobi, Kenya: Characteristics and Outcomes Jeffrey K. Edwards 1, Helen.](https://reader038.fdocuments.in/reader038/viewer/2022110207/56649d745503460f94a53949/html5/thumbnails/6.jpg)
The main components of the programme included:
A holistic team of health staff (clinical officers, nurses, nutritionists, health educators, social workers and adherence counsellors)
Offer of a package of care (clinical care, nutritional and social support, and education on life style measures, diseases and treatment)
Cohort outcome data monitoring

RESULTSChronic kidney disease within the cohort
The frequency of chronic kidney disease (CKD = creatinine clearance < 60 ml/min) in the combined cohort was 15% (266/1802)
There were no differences between the frequency of CKD in people living with HIV (PLHIV) vs. those without HIV.
Of those with CKD within the cohort, 15% (41/266) had concurrent Type 1 or 2 diabetes mellitus.
There was no association found between the use of tenofovir and CKD among PLHIV.
The median age for those with PLHIV and CKD was 47 (IQR 41-54) vs. 59 (49-70) years without HIV (p < 0.0001).

Short-term monitoring of 3.5 years: no possibility to assess reduction in morbidity and mortality
Poor documentation of complications at baseline and during follow up
LIMITATIONS
![Page 17: Integration of HIV and Non-communicable Disease management into Primary Care in Nairobi, Kenya: Characteristics and Outcomes Jeffrey K. Edwards 1, Helen.](https://reader038.fdocuments.in/reader038/viewer/2022110207/56649d745503460f94a53949/html5/thumbnails/17.jpg)
This study provides a “real world” assessment of an integrated primary care program from an informal settlement
Standardized treatment protocols were used for hypertension, diabetes, CKD and HIV that were aligned with international guidelines
Program was primarily run by clinical officers and nursing staff
Routine data monitoring was completed
Strengths
![Page 18: Integration of HIV and Non-communicable Disease management into Primary Care in Nairobi, Kenya: Characteristics and Outcomes Jeffrey K. Edwards 1, Helen.](https://reader038.fdocuments.in/reader038/viewer/2022110207/56649d745503460f94a53949/html5/thumbnails/18.jpg)
This study highlights the need to recognize the increasing chronic disease burden in sub-Saharan Africa.
PLHA appear to be at higher risk of developing concurrent NCDs at a younger age, and would benefit from routine surveillance for them.
It is possible to integrate both HIV and NCD care together in a primary care programme
This integrated programme can be run by clinical officers and nursing staff within significant resource constraints.
