Time trends in gastroparesis treatment.

INTRODUCTION

While delayed emptying is the defining criterion for gastroparesis, prokinetics often only have a limited impact on symptoms and have been associated with potentially serious adverse effects. The goal of this study was to determine how this information and regulatory changes affected gastroparesis management.

METHODS

The electronic medical records of patients seen between 2003 and 2012 in the outpatient clinic of a large tertiary center were retrieved based on the billing diagnosis of gastroparesis. Demographic, clinical, and survival data were abstracted.

RESULTS

A total of 709 patients were identified, with diabetes (21.2 %) and prior surgery (9.8 %) being the most common identifiable causes. The majority of patients (56 %) had idiopathic gastroparesis. The cohort was female predominant (79.5 %) with an average age of 45.4 ± 0.6 years. At the index encounter, 61.8 % received prokinetics. About one-third (37.7 %) used antiemetics at least intermittently. Between 2003 and 2012, prokinetic use dropped from 81 to 43 %, while the use of antiemetics increased from 14 to 41 %. Similarly, there was a significant increase in prescribed opioids and antidepressants. During the period of the study, 44 patients (6.2 %) died. Increasing age, a higher comorbidity burden, anxiety, and medication use were associated with higher mortality risks.

CONCLUSION

This large outpatient cohort suggests that treatment trends move away from prokinetics and focus on symptom-oriented therapy and/or confounding mood disorders.
