Your patients leave. The hard part begins.
Cardiac patients do better with peer support — the research is clear. Dude2Dude provides the structured, peer-driven recovery community your discharge process is missing.
The Business Problem We're Solving
Discharge used to be the finish line. It isn't anymore. A single 30-day cardiac readmission costs a hospital an average of $17,5002— and since January 1, 2026, CMS's Transforming Episode Accountability Model (TEAM)7 makes hospitals financially accountable for every dollar of Medicare spending in the 30 days after a cardiac surgery discharge, not just readmissions. Layer that on top of the existing Hospital Readmissions Reduction Program (HRRP)6, which already penalizes 78.2% of U.S. hospitals this year, and the 30 days after surgery have become one of the highest-stakes windows in a hospital's financial year.
The clinical evidence on what closes that gap is unusually consistent: peer support. Sixteen randomized controlled trials, over 2,000 patients3, and a peer-advisor RCT specific to cardiac rehab4all point the same direction — patients who have someone who's walked the same road show up more, stay engaged longer, and return to the hospital less. Dude2Dude is built to be that someone, at scale, without adding to your care team's workload.
And the upside isn't only about avoiding penalties. Since 2012, HCAHPS patient-satisfaction scores have determined a share of every hospital's Medicare reimbursement through the Hospital Value-Based Purchasing Program8 — patient experience is revenue, not just goodwill. A less anxious, better-supported patient is a more satisfied one.
“Show Me the Money” — For CFOs
Everything above is the national picture. The calculator below turns it into your hospital's own numbers.
Estimate your hospital's impact
A conservative, publicly-sourced estimate — not specific to any one hospital's payer mix or contract.
Scenario
Five inputs below are Dude2Dude-specific assumptions, not external facts — a single default invites the question “why that number?” This track shows the plausible range at a glance instead.
Conservative — the low end of a defensible range, assuming real-world results underperform published research. Realistic— the calculator's own default, already discounted below the cited research. Optimistic— the high end; where a citation exists, this is the study's own reported result. The two ticks in between are plain midpoints between their neighbors, not separate published estimates.

Program Inputs
Procedures requiring hospitalization, surgery, and hospital recovery — excludes outpatient procedures.
Illustrative adoption scenarios, not a specific published benchmark — adjust to match comparable programs at your hospital.
Higher MA penetration means less Traditional Medicare — reduces ED cost exposure. 70% total Medicare share is a typical cardiac-surgery estimate, not independently sourced.
Defaults to the $17,500 AHRQ national average2 — use your own negotiated case rate or cost-per-case if you have one, since this is the single biggest driver of Cost Savings.
Of patients who'd otherwise be readmitted, the share Dude2Dude keeps out of the hospital. Weddell et al. 20253found a 75% relative reduction across 16 RCTs (95% CI 40%–90%) — our realistic default sits conservatively below even the weak end of that trial's own confidence interval, and the optimistic anchor is the trial's reported point estimate. Conservative (10%) is an illustrative floor for real-world engagement underperforming a controlled trial — it is not drawn from the CI itself.
Baseline: 109/yr (−25% with D2D3)
= 27 × $17,500 = $473K saved
Based on 960 patients referred annually (576 engaged). ED-visit rate (12%)10 and avg. cost ($700)11 are both independently sourced, scoped to Traditional Medicare patients.
Net New Revenue
$533K/yr at full program adoption
Extra share of engaged patients D2D moves into cardiac rehab — national start rate is just 29%. Carroll et al.4 found a significant increase in participation without reporting an exact percentage-point lift, so these anchors are illustrative, not drawn from that trial's numbers.
Medicare hospital-outpatient runs ~$130–175; commercial payers often net $500–800+ (fee-schedule ranges, not independently sourced)
This one is yours to set — bed-day value varies too much by hospital and service line for a national default. A 30-day readmission averages ~6 inpatient days, per Mayr et al., JAMA (2017)9.
Year 1: = 14 readmissions avoided × 6 days = 81 bed-days freed

Not counted above
There are four real value drivers with no defensible dollar figure to plug into a slider. The first three depend on your hospital's penalty status, VBP score, and payer mix, so we model them directly with partner hospitals. The fourth has no study behind it at all — see sources below. Every readmission your program avoids moves the first three of these in your favor — the fourth only requires a patient willing to tell their story.
HRRP penalty exposure6
Up to 3% of all Medicare payments
78.2% of hospitals face a Hospital Readmissions Reduction Program penalty in FY2026 — cutting a hospital's total Medicare base operating payments, not just cardiac.
TEAM accountability7
30 days of post-discharge spend
Mandatory since January 2026. Hospitals are financially accountable for all Medicare Parts A/B spending in the 30 days after a cardiac surgery discharge.
Patient satisfaction revenue8
Tied to HCAHPS since 2012
Patient-satisfaction scores determine a share of Medicare reimbursement through the Value-Based Purchasing Program — a less anxious, better-supported patient is a more satisfied one.
Raving fans12
50% choose a doctor by word-of-mouth
A satisfied patient telling their story is real marketing value — but no study puts a defensible dollar figure on a referred patient for a specific hospital, so we don't estimate one.

Peer advisors significantly increase cardiac rehab participation
Carroll, Rankin & Cooper, Journal of Cardiovascular Nursing (2007)
Randomized trial of 247 unpartnered older adults after MI or CABG. The peer-advisor group showed significantly more cardiac rehab participation at 3 months, an effect that held for a full year, with a trend toward fewer rehospitalizations.

Patient experience is tied directly to reimbursement
CMS, Hospital Value-Based Purchasing Program
Since 2012, HCAHPS patient-satisfaction scores have determined a share of a hospital's Medicare reimbursement. Better patient experience isn't just goodwill — it's revenue. A small pilot of peer coaching for post-CABG patients found a 9.0/10 average score for reducing fear and anxiety, with 100% of patients recommending the program.

A 30-day cardiac readmission averages 5.7–6.4 days
Mayr et al., JAMA (2017), 2013 Nationwide Readmissions Database
Every avoided readmission frees up roughly six inpatient bed-days — capacity that could otherwise go to a new or waiting patient, including the diagnosis-to-surgery queue.

12% of CABG patients visit the ED within 30 days without being readmitted
Fox et al., Annals of Thoracic Surgery (2013)
63,911 CABG patients across 114 California hospitals. Median hospital 30-day ED-visit-without-readmission rate was 11.9% (IQR 10.5%–13.7%), nearly matching the readmission rate itself — a separate, meaningful driver of post-discharge acute care cost.

Half of patients choose a new doctor by word-of-mouth
Tu & Lauer, Center for Studying Health System Change, Research Brief No. 9 (2008)
National consumer survey found word-of-mouth from friends and family was the single largest information source patients used when choosing a new primary care physician — ahead of doctor recommendations (38%) or health plan information (35%). No study puts a defensible dollar figure on a referred patient's value to a specific hospital, so we don't model it here.
