In response to the question asking about the patient-related factors that make PCPs reluctant to prescribe insulin, physicians were reluctant to initiate insulin for T2D patients mostly due to patient non-adherence to self-monitoring of blood glucose (SMBG) (73.6%), non-adherence to appointment or treatment (52.1%), old patients due to fear of hypoglycemia (51.4%), or due to patient refusal (41.7%). Here, INS is linked to type 2 diabetes mellitus.
