Despite its benefits, the implementation of PCMH faces several challenges: - Resource Allocation: Establishing and maintaining a PCMH requires significant investment in infrastructure, technology, and training. - Care Coordination: Effective coordination among various healthcare providers and services can be complex and time-consuming. - Patient Engagement: Ensuring active participation from patients in their care plans can be challenging, especially for those with low health literacy or socioeconomic barriers. - Measurement and Evaluation: Developing standardized metrics to evaluate the effectiveness of PCMH and ensuring data accuracy can be difficult.
