Brief Summary

This study used an observational, retrospective cohort design to compare the presence and timing of new-onset diabetes (NOD) between hypertensive patients initiating therapy with carvedilol immediate-release (IR) and carvedilol controlled-release (CR) vs the following cardioselective beta blockers (BBs): atenolol, metoprolol succinate, and metoprolol tartrate (referred to hereafter as 'other BB').

The aim of the study was to investigate the likelihood of developing NOD among hypertensive patients initiating carvedilol therapy vs other BB therapy in a real world setting derived from data contained in a large United States (US) managed care database.

Detailed Description Not Provided
Study Type Observational
Study Design Time Perspective: Retrospective
Target Follow-Up Duration Not Provided
Biospecimen Not Provided
Sampling Method Non-Probability Sample
Study Population This retrospective database study identified patients aged ≥18 years with at least one pharmacy claim for a beta-blocker of interest (carvedilol immediate-release [IR]/controlled-release [CR], atenolol, metoprolol succinate, or metoprolol tartrate) identified in the IMS LifeLink Health Plan Claims Database. Index date was the first chronologically occurring prescription for any beta-blocker during the enrollment period (July 1, 2000-December 31, 2007). Patients were identified if they were continuously eligible to receive healthcare services 6 months prior to and 3 months after the index date and at least 1 diagnosis of hypertension (ICD-9-CM: 401.xx-405.xx) during this time frame.
