Abstract
The healthcare system’s major purpose is quality, but many times, it is getting challenging due to economic and health crises. One of these aspects is corruption with informal payments, expressed by illegal amounts from patients to healthcare staff to receive qualitative care. Contains black payments (better treatment), lost payments (equal or worst treatment), grey payments (undeclared payments with tax returns), and gratitude payments (bad healthcare). Greece is a country where informal payments are most detected, with less public revenue, delay in economic growth, and lack of financial sustainability. We focus on informal health payments in Greece and on effective solutions aiming to eliminate the phenomenon. More information must be given about the types of healthcare corruption and aspects of informal out-of-pocket healthcare payments globally and especially in Greece through surveys. However, are insufficient which argued by specific measures to prevent corrupt practices in health and secure a healthcare system with qualitative issues, i.e., elective surgery list, complaints of patients in healthcare authorities, sanctions, etc.
