Objective:

To assess the quality and compliance of clinical practice guidelines (CPG) applicable to chronic non-communicable diseases (CNCD) in primary healthcare (CS), and views of staff on the barriers, facilitators and their use.

Materials and methods:

18 valued CPG with AGREEII, 3 are selected to develop indicators and assess compliance using lot quality acceptance sample (LQAS, standard 75 / 95% threshold 40 / 75% respectively, α:0. 05, β:0. 10) on 5 CS. 70 professionals surveyed about knowledge and use of CPG.

Results:

Average quality of the CPG was 57.2%; low rating in domains: “Applicability” (<25%), “Stakeholder involvement” (43.5%) and “Rigour of development” (55.0%). Compliance in CS ranges from 39 to 53.4%. Professionals show uneven knowledge of CPG; 44 to 45% (according to CPG), they declare that they are not used, they identify as main barriers the lack of training, and their difficult accessibility and management.

Conclusions:

The quality and implementation of evaluated CPG is deficient constituting an opportunity of improvement in health services.
