Noah’s Export and Import function is a highly effective method to combine and merge records into an already existing database. HIMSA has documented though that very large database exports can sometimes have issues importing where the import may time-out before completion, especially on older machines.
To avoid errors and inform of the issue, HIMSA is including a new warning message when exporting and importing nhax files that contain over 5000 records: ‘Your import has exceeded HIMSA’s supported number of patients. HIMSA recommends that you import the desired patient records in smaller groups not exceeding 5,000.’
