Critique of the Project RED Randomized Trial of a Reengineered Hospital Discharge

The Study Under Review

This critique reviews the Project RED trial, published in Annals of Internal Medicine by a Boston Medical Center team (Jack et al., 2009). I chose it from my annotated bibliography because it tests a complete discharge bundle against usual care, which is the kind of solution my capstone will propose.

Purpose and Question

Jack et al. (2009) asked whether a redesigned discharge process, delivered by a nurse in the hospital and reinforced by a pharmacist by telephone after discharge, would reduce hospital use in the month after patients went home. The main outcome counted every return to the hospital in the following month, whether to the emergency department or to an inpatient bed.

Design and Sample

This was a randomized controlled trial on the general medical service of an urban academic safety-net hospital in Boston. Researchers enrolled 749 hospitalized adults who spoke English, with a mean age of about 50. Assignment used blocks of six and eight, with index cards in sealed, numbered envelopes, which kept recruiters from predicting the next allocation. The analysis compared 370 intervention patients with 368 receiving usual care.

Intervention

A nurse discharge advocate met patients during the stay to schedule follow-up appointments, confirm that the medication list had been reconciled and teach from an individualized booklet. The booklet also went to the patient's primary care provider. Two to four days after discharge, a clinical pharmacist called to go over the plan and the medicines again.

Measures and Analysis

Hospital use within 30 days came from hospital records and from telephone interviews with participants, and the research assistants who made the follow-up calls were kept unaware of each patient's assignment. Secondary outcomes included how prepared patients felt for discharge and whether they saw their primary care provider within 30 days. Rates were compared as visits per person per month.

Results

The intervention group used the hospital less, at a monthly rate of 0.314 visits per person against 0.451 under usual care, an incidence rate ratio of 0.695 (95% CI, 0.515 to 0.937; P = 0.009). Put plainly, hospital use fell by roughly 30%. The program helped most among patients who had been hospitalized or seen in the emergency department in the six months before the index stay.

Critique: Internal Validity

Strengths: Concealed allocation protected randomization, the groups were compared as assigned and the people collecting outcomes were blinded. The intervention is described step by step, so a reader knows what produced the effect. Limitations: Patients and clinicians knew who received the program, and some outcome data relied on what participants remembered, which could tilt results if intervention patients reported more carefully. The abstract also notes that adverse events were collected but not yet analyzed, so the trial cannot say whether the program prevented injuries as well as visits.

Critique: External Validity

One hospital, a relatively young population and an English-only sample limit how far the result travels. My community hospital serves many older adults and a large Spanish-speaking population, so the booklet, the teaching and the pharmacist call would all need to work in Spanish before I could expect similar results. The study also predates the Medicare readmission penalty, and a meta-analysis of 42 trials found that newer trials report smaller effects (Leppin et al., 2014), so a smaller benefit is the honest expectation.

Implications for My Capstone

Project RED gives my program a tested core: a named person who owns the discharge, a reconciled medication list, an appointment made before the patient leaves, a summary sent to the clinic and a call within days. I will add bilingual staff, target patients with recent hospital use, where the trial saw its largest benefit, and measure injuries as well as visits, since drug-related harm is the most common injury in the weeks after discharge (Forster et al., 2003).

Conclusion

Project RED is a well-protected trial with a meaningful effect on hospital use. Its single-site, English-only sample means my capstone should adapt it with care and measure the results locally.
