Purpose:
The cardiac rehabilitation (CR) program at Dartmouth-Hitchcock Medical Center (DHMC) devotes a nurse to the inpatient units in an attempt to optimize the referral process. This report defines the rates of referral and participation at DHMC and explores potential factors that affect participation.
Methods:
Seven hundred ten consecutive patients who underwent percutaneous coronary intervention, coronary artery bypass grafting, or valve surgery from January 1, 2015 to June 30, 2015 were reviewed to determine whether the patient was referred for CR. Participation rates and the effect of time delay and patient-specific factors on participation were examined.
Results:
Six hundred ninety-eight (98%) of the 710 post-procedural patients were evaluated by the inpatient rehabilitation nurse. One hundred sixty-seven patients were ineligible for outpatient therapy on the basis of established criteria; the remaining 543 patients were referred to DHMC or regional rehabilitation programs. Of those referred to the on-site program at DHMC, 84% participated. Of those referred to regional programs, 60% participated. There was an inverse correlation (r = -0.82; P = .003) between wait times and participation rates for the various programs.
Conclusions:
Despite its rural location with a large geographic catchment area, DHMC achieves high rates of CR referral and participation. The approach used at DHMC, which includes a CR nurse working with the inpatient cardiac services, a strong level of integration with the physician community, and well-developed relationships with regional rehabilitation programs, may be helpful for those programs wishing to improve referral and participation rates. Shorter wait times between hospital discharge and initiation of rehabilitation may improve participation rates.

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
