While there may be many reasons you are looking to change your EHR, take time to isolate the primary reasons that your EHR is negatively impacting your day-to-day routine. Some things to consider:
Cost: Is your EHR too expensive? Were you promised one price but come to find out after a year the price increased? Are you being charged for updates?
Decrease in Productivity: Have you noticed you are not seeing as many patients? Is it taking your staff too long to finalize things within your EHR?
Government Incentives/Meaningful Use/Certification: Does your EHR not meet the criteria for Government incentives? Is it too difficult to achieve MU with your current EHR?
Customer Support: Is support terrible? Is support hard to understand because it is outsourced to someone in another country? Is it not available 24/7?
This is a first/major step in your EHR switch process. Once you know where it hurts you can look for better a solution!
