Key result

Inpatient attending role linked to ~34% higher self-reported beta-blocker prescribing in heart failure.

  • P=0.002
  • n=69

Why the study?

Beta-blockers reduce mortality in systolic heart failure, yet primary care provider prescription rates remain low, motivating examination of physician factors influencing prescribing.

Population

69 primary care providers at three New York City Veterans Affairs medical centers

Comparison

Physicians serving as inpatient ward attendings and with high confidence vs those not serving and with lower confidence

Design

Cross-sectional survey with retrospective chart review

Overview

Teaching attendings report higher self-reported beta-blocker use in HF; hypothesis-generating for education effects but needs objective data before practice implications.

Study Design

Type

Cross-Sectional (n=69)

Multicenter

Yes

Structured PICO

P
Population
69 primary care physicians (mean age 45, 51% female) at three NYC VA medical centers, and a matched cohort of 287 of their patients with systolic heart failure.
O
Outcome
1) self-reported prescribing of beta-blockers, and 2) actual prescribing of beta-blockers among HF patients

Main Result

Absolute Event Rate: 78% vs 58%

p-value: p=0.002

Physician teaching responsibilities and confidence levels are associated with higher self-reported beta-blocker prescribing for heart failure patients, suggesting that educational efforts may improve guideline adherence in primary care.

Limitations

  • Small sample size which may have limited power to detect differences in actual prescribing rates
  • Only examined beta-blocker prescribing and did not address other dimensions of heart failure care quality
  • Unable to examine actual patient adherence to prescribed medications
  • Limited to physicians and patients at three New York City-based VA medical centers, which may limit generalizability
  • small sample size
  • limited power to detect true differences in actual prescribing rates
  • only examined beta-blocker prescribing and not other dimensions of HF care quality

Cite This Study

Sinha et al. (2009) conducted a cross-sectional in Systolic heart failure (n=69). Inpatient ward attending responsibilities vs. No inpatient ward attending responsibilities was evaluated on Self-reported prescribing of beta-blockers among heart failure patients (p=0.002). Physicians who served as inpatient ward attendings self-reported significantly higher rates of beta-blocker prescribing among their heart failure patients compared with physicians who did not (78% vs. 58%).
