The intervention included a nurse led self-care education program, structured hospital discharge summaries, and a family physician follow-up within 1 week after discharge and/or structured nurse home visits followed by more frequent heart failure clinic follow-ups for people with low-complexity heart failure.2

Study investigators speculated a few possible reasons for the lack of benefit. First, they felt that services shown to be effective in previous randomized controlled trials may not have been effective when applied to a healthcare system. Further, the trial included patients with “suboptimal health literacy or self-care” and these patients had an overall higher prevalence of comorbid conditions when compared with patients included in prior randomized controlled trials. Last, unlike prior randomized controlled trials looking at patient-centered transitional care, this trial titrated efforts to risk such that only those patients with the highest risk got home visits and heart failure clinic follow up.2

Although the national readmission rates for ambulatory care-sensitive conditions have dropped since the HRRP was implemented, there is growing concern that the program may have provided incentives for physicians and hospitals in the wrong direction.

An article published in 2018 recognized that financial penalties may have led some physicians to inadvertently avoid readmissions that were indicated.3 In a study aimed at determining whether the implementation of HRRPs was associated with an increase in patient-level mortality, investigators identified a significant increase in postdischarge mortality for patients hospitalized with heart failure and/or pneumonia.3 The study looked at 8.3 million hospitalizations among Medicare beneficiaries for heart failure, acute myocardial infarction, and pneumonia. Although the HRRP was associated with a 0.9% reduction in 30-day and 1-year readmissions, researchers found that there was an overall increase in 30-day and 1-year mortality from 31.3% to 36.3% or hazard ratio of 1.1.3

Thus, the situation is complicated. On one hand, patient-centered transitional care services applied to specific populations with ambulatory care-sensitive conditions have been shown in randomized controlled trials to be beneficial at reducing readmissions and overall cost of healthcare. However, when applied to all patients with heart failure within a health system, the same interventions did not yield a measurable improvement in readmission rates.2 In some cases, providing incentives for physicians and hospitals to avoid readmissions for sick patients with chronic diseases may be inadvertently increasing mortality for those patients, thereby blunting the expected benefit of offering patients improved transitional care services.3

I suspect that Bayes’ theorem may apply here. Patients with chronic conditions who are at low risk are likely already doing very well. Very few resources are needed to keep them stable and out of the hospital. Likewise, patients with chronic conditions at high risk may be so sick that it does not matter how much support is thrown their way. They are not going to get better and it may be reasonable to consider palliative care services or more advanced therapies if they qualify (eg, transplant in people with heart failure).

Therefore, the highest benefit for HRRPs may be in targeting those at intermediate risk who are more likely to benefit from standardized care and guideline-directed medical therapy so that they can return to the low risk categories or so that their disease does not progress to a higher-risk state. Unfortunately, identifying these patients early can be tricky. Current risk scores for assessing risk in heart failure have been either too cumbersome or mediocre at best.

In the meantime, as we all work diligently to try to figure out how to best care for these chronic conditions, it may help for Centers for Medicare and Medicaid to reduce pressure. By allowing exemptions that take into account not only the patient’s overall prognosis but also their willingness to comply with guideline-directed medical therapy, hospitals and physicians would be able to focus more of their resources toward a population of patients most likely to benefit from transitional care services.
