Objectives
The Carlos Slim Foundation implemented the Integrated Measurement
for Early Detection (MIDO), a screening strategy for non-communicable
diseases (NCDs) in Mexico as part of CASALUD, a portfolio of digital
health services focusing on healthcare delivery and
prevention/management of NCDs. We investigated the disease profile of
the screened population and evaluated MIDO’s contribution to the
continuum of care of the main NCDs.
Design
Using data from MIDO and the chronic diseases information system, we
quantified the proportion of the population screened and diagnosed with
NCDs, and measured care linkage/retention and level of control achieved.
We analysed comorbidity patterns and estimated prevalence of predisease
stages. Finally, we estimated characteristics associated with
unawareness and control of NCDs, and examined efficacy of the CASALUD
model in improving NCD control.
Setting
Public primary health centres in 27/32 Mexican states.
Participants
Individuals aged ≥20 years lacking healthcare access.
Results
From 2014 to 2018, 743 000 individuals were screened using MIDO. A
predisease or disease condition was detected in ≥70% of the population
who were unaware of their NCD status. The screening identified 38 417
new cases of type 2 diabetes, 53 133 new cases of hypertension and
208 627 individuals with obesity. Dyslipidaemia was found in 77.3% of
individuals with available blood samples. Comorbidities were highly
prevalent, especially in people with obesity. Only 5.47% (n=17 774) of
individuals were linked with their corresponding primary health centre.
Factors associated with unawareness of and uncontrolled NCDs were sex,
age, and social determinants, for example, rural/urban environment,
access to healthcare service, and education level. Patients with type 2
diabetes treated at clinics under the CASALUD model were more likely to
achieve disease control (OR: 1.32, 95% CI: 1.09 to 1.61).
Conclusion
Patient-centred screening strategies such as MIDO are urgently
needed to improve screening, access, retention and control for patients
with NCDs.
