Patients with benign upper gastrointestinal (UGI) conditions such as achalasia, gastroparesis and refractory gastroesophageal reflux disease often suffer from debilitating symptoms. These conditions can be complex and challenging to diagnose and treat, making them well suited for discussion within a multidisciplinary meeting (MDM). There is, however, a paucity of data describing the value of a benign UGI MDM.

Article Synopsis
  • Patients with opioid use disorder (OUD) often utilize emergency services and hospitals more, and the PROUD trial aimed to see if office-based addiction treatment (OBAT) could help reduce this.
  • The trial involved 12 clinics and focused on OUD patients, comparing outcomes between those receiving OBAT and usual care over two years after treatment began.
  • Results showed that, despite increased treatment days for intervention patients, there was no significant difference in emergency or hospital utilization between the OBAT and usual care groups for both pre- and post-randomization patients.
