Background:
Throughout the whole care cycle, IPUs are positioned functionally around the health issue. A committed multidisciplinary team that operates as a unique organizational unit prioritizes the patients needs, offering various health services. This reviews objectives are to describe and examine IPUs, evaluate their effectiveness, and provide suggestions for future integration initiatives.

Methods:
In March 2022, three search queries were introduced on different Academic Databases. Only 61 publications were chosen in a double-blind review by two separate researchers out of 1300 findings, using inclusion and exclusion criteria.

Results:
“Integrated Care Model” and “Integrated Practice Units” were the most commonly used terms to allude to integration in the collected papers, 57% and 26%, respectively. 85% of the studies addressed chronic illnesses. Primary medical centres and tertiary facilities comprised the bulk of integrated delivery models, 51% and 49%, respectively. The most prominent professional category was the speciality consultant (80%). Only 16% of the initiatives had a well-defined finance model, with public funding predominating on private ones. Numerous research (82%) that primarily evaluated clinical outcomes demonstrated improved results.

Conclusions:
Research showed that care integration had a favourable effect on medical expenses and clinical results. IPUs continue to receive scant citations in the literature, demonstrating a paucity of comprehensive and well-organized integration. Due to the underreporting of financial information, further study and work are required to fully understand values-based payments.
