Complications and outcomes of hospitalizations for patients with and without Parkinson disease.

Objective: To examine complications and outcomes of hospitalizations for common indications for hospitalization among patients with Parkinson disease (PD).

Methods: We identified and selected the ten most common indications for hospitalization among individuals ≥65 years of age using principal diagnoses from the California State Inpatient Database, 2018-2020. Patients with comorbid PD were identified using secondary diagnosis codes and matched one-to-one to patients without PD based on principal diagnosis (exact matching), age, gender, race and ethnicity, and Elixhauser comorbidity index (coarsened exact matching).

Interpretation of urine drug testing results in patients using transdermal buprenorphine preparations for the treatment of chronic noncancer pain.

Objective: To determine whether the prevailing liquid chromatography and tandem mass spectroscopy assay (LC-MS/MS) assay designed to monitor buprenorphine compliance of the sublingual formulation used in the substance abuse treatment setting can be extrapolated to the transdermal formulation used in the chronic pain treatment setting, which is 1000-fold less concentrated.

Design: Retrospective chart review.

Subjects: Self-reported compliant patients using the transdermal or sublingual formulations of buprenorhphine.
