After a CPAP titration study, the next step to confirm patient setup at home is to:

Having the selected provider confirm the patient's setup at home is a critical step following a CPAP titration study. This ensures that the equipment being used is properly configured according to the settings determined during the titration study. The provider's expertise is crucial in reviewing the patient's adherence to therapy, troubleshooting any issues, and ensuring that the CPAP device is functioning correctly. This helps in maintaining effective treatment of sleep apnea, as any misconfigurations or misunderstandings in setup could lead to inadequate therapy and poor patient outcomes. By confirming the setup, the provider can also provide necessary education and support to the patient, enhancing compliance and effectiveness of the treatment plan.

In contrast, contacting the physician or calling the insurance company are not direct actions focused on confirming the setup itself, and simply checking with the patient may not yield the most accurate or technically sound assessment of their CPAP setup. Therefore, engaging the provider who is familiar with the specific details of the case is the most appropriate course of action.
