Critical pathway
Background: Evidence-based therapies can lower the risk of death or hospital admission in heart failure (HF)
patients, but are underprescribed. Critical pathways are one means of supporting systematic use of evidence-
based recommendations.
Methods: Patients admitted for HF in one hospital in 2009 and included in a critical pathway were compared
with a control group of patients admitted in 2007. The primary endpoint was the risk of death or readmission
within 90 days after discharge. The hazard ratio of death or readmission was evaluated in a multivariate Cox
proportional hazard model adjusting for age, sex, co-morbidities, and length of stay.
Results: Three hundred and sixty-three patients were evaluated (151 in the critical pathway and 212 in the
control group). Adjusted hazard ratio for death or readmission at 90 days was 0.72 (95 CI 0.51–1.00,
p = 0.049). Adhesion to guidelines was significantly better for patients included in the critical pathway
(p = 0.004), with more frequent prescription of beta-blockers (70.9% (95% CI 62.9–78.0) vs. 56.6% (95% CI
49.6–63.4), p = 0.006), and evaluation of left ventricular ejection fraction (LVEF, 73.5% (95% CI 65.7–80.3)
vs. 57.5% (95% CI 50.6–64.3), p = 0.002). Patients with reduced LVEF seem to have benefited the most from
the inclusion in the critical pathway.
Conclusions: Implementation of a critical pathway for patients hospitalized for HF was associated with a 28%
reduction of the relative risk of death or readmission and improved adhesion to guidelines.

1. Introduction
The prevalence of chronic heart failure (HF) is estimated at 1–2%
in developed countries [1] and rises sharply with age, with 10 to
20% of people aged over 75 years being affected [2]. Mortality can
reach 11% at 30 days and 37% at 1 year among elderly patients admit-
ted for HF [3]. HF hospitalizations account for 5% of all hospital admis-
sions [4]. The risk of readmission after a first hospitalization for HF
can reach 20 to 25% at 30 days and 40 to 50% at 90 days [3,5,6]. Mul-
tiple admissions do not only impact heavily on the quality of life of
patients but are also associated with increased subsequent mortality
[7,8].
Angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin-
receptor blockers (ARBs) [9], beta-blockers [10], mineralocorticoid
receptor antagonists (MRAs) [11,12], cardiac resynchronization ther-
apy (CRT) in selected patients [13], and intensive case management
for ambulatory patients [14] have all been shown to reduce the risk
of hospital admission in chronic HF with reduced left ventricular ejec-
tion fraction (LVEF). Even if these evidence-based therapies are wide-
ly diffused in national and international guidelines [15–17], their
underuse has been repeatedly documented, particularly for beta
blockers and MRAs [18–20].
A critical (or clinical) pathway is an organizational tool for im-
proving the quality of care delivery [21]. It is developed through a
multidisciplinary analysis of the process of care, and based on the
best available evidence. Its physical substrate is mainly document-
based, consisting of medical records, operating procedures, and care
plans [22]. Formal evaluations of critical pathways have suggested
that they can be useful for decreasing length of stay, total costs, and
mortality in chronic HF inpatients [23]. However, these benefits
have not been replicated in all settings [24]. We aimed to test the abil-
ity of a computer-based critical pathway to lower the risk of death
and readmission and to improve the quality of care in a cohort of pa-
tients admitted for HF.
