Ready to Go Home? Assessment of Shared Mental Models of the Patient and Discharging Team Regarding Readiness for Hospital Discharge

Our study applied novel approaches to explore the interprofessional teams’ understanding of discharge readiness, a concept known to be an important predictor of patient outcomes after discharge, including readmission.^20,28 We found that discharge teams frequently had poor quality SMMs of hospital discharge readiness. Despite having a discharge order and receiving home care instructions, one in four patients reported low readiness for hospital discharge. Additionally, discharge teams frequently overestimated patient’s readiness for hospital discharge. Misalignment on patient readiness for discharge occurred both within the discharge team (ie, low team convergence) and between patients and their care teams (ie, low team-patient convergence). The potential importance of this disagreement is substantiated by prior work suggesting that divergence in readiness ratings between nurses and patients are associated with postdischarge coping difficulties.²⁸

Previous readiness for discharge has been measured from the perspective of the patient,^20,21,27,28 nurse,^20,25-28 and physician,³⁷ yet rarely has the teams’ perspective been examined. We add to this literature by measuring the team’s perspective, as well as agreement between team and patient, on the individual patient’s readiness for discharge. Notably, we found that higher-quality communication is positively related to teams’ assessment of discharge readiness, with teams that reported higher quality teamwork having more convergent team-patient SMMs. Our results support many qualitative studies identifying communication and teamwork as major factors in teams’ effectiveness in discharge planning.^1-7,9 However, given the small sample size in this study, additional research is needed to further understand these relationships, as well as link SMMs to patient outcomes such as hospital readmission.

In an attempt to improve discharge planning, hospitals are increasingly assessing readiness for discharge as a low-intensity, low-cost intervention.^26,27 Yet, recent evidence suggests that readiness assessments alone have minimal impact on reducing hospital readmissions.²⁶ To be successful, these assessments likely depend on quality interprofessional communication and ensuring the patient’s voice is incorporated into the discharge decision process.²⁶ However, there have been few ways to effectively evaluate these types of team interventions.⁹ Measuring SMM properties holds promise for identifying specific team mechanisms that may influence the effectiveness and fidelity of interventions for team-based discharge planning. As our findings indicate, SMMs provide a theoretical and methodological basis for evaluating if readiness for discharge was team based (convergence among team members) and patient centered (convergence among team assessment and patient self-assessment). Researchers and improvement scientists can use the approach outlined to evaluate team-based patient-centered interventions for hospital discharge planning.⁹

This study provides a unique contribution to the growing work in the team science of SMMs.^9,10 We rigorously evaluated SMMs of key stakeholders (patients and their interprofessional team) in “real-time” clinical practice using a patient-centered assessment linked with postdischarge outcomes.^20,27,28 However, it is still unknown how much convergence is needed (and with whom) to safely discharge patients.¹³ Prior studies suggest highly convergent SMMs increase team performance when they are also accurate.^10-13 Convergence alone should not be sought because this may reflect groupthink or clinical inertia.^10,15 To improve discharge team performance over time,^10‑13 it is important to assess not only patient’s readiness on the day of discharge but also how prepared the patient actually was for the recovery period following acute care. In the larger mixed-methods study, we found that teams’ with more convergent SMMs on teamwork quality were associated with patient’s reported quality of transition 30-days after discharge.⁹ Together, these findings further highlight the importance of aligning patient and interprofessional team members perspectives during the discharge planning, as well as providing clinicians with regular feedback about patient’s postdischarge experiences and outcomes.

To optimize team performance, the discharge planning process must be considered from an interprofessional team perspective as it functions in real-world practice settings. There are increasing pressures to discharge patients “quicker and sicker,” to simplify and standardize clinical process, and to provide patient-centered care.^3,5-8 Without thoughtful interventions to facilitate communication during discharge planning, these pressures likely reinforce inaccurate assumptions regarding the work of fellow team members and force teams to think “fast” instead of “slow.”^38-40 One approach to overcome such barriers is to focus on building a high-quality interprofessional SMM around discharge readiness. For example, the RHDS/SF questions could be integrated into the electronic medical records, displayed on dashboards, and discussed regularly during discharge rounds. In particular, to strengthen the team’s SMM and quality of teamwork, together the staff can ask three practical questions (Appendix F): (1) Do we think the patient is ready for discharge? (2) To what extent do we all agree the patient is ready for discharge? (3) Does our assessment of discharge readiness match the patient’s? During this high-risk transition point, asking these questions might allow the team to move from thinking fast to thinking slowly so they can more effectively identify heuristics they may be using inaccurately, prevent blind spots, and move toward high reliability.^{10,13,18,38-40}

This study has limitations. First, events were recruited from patients with any of only six conditions at a single hospital. Other settings, patient condition types, or team compositions of other clinicians may differ in results. Second, in this study the SMM content was focused on readiness for hospital discharge among four key stakeholders. It is possible other SMM content needs to be shared among the interprofessional discharge team (eg, caregivers’ perspectives,^2,6-8 resource availability,^3-6 clinicians’ roles^4,9) or additional members should be included (eg, physical therapists, nursing assistants, home health consultants, or primary care clinicians). Although this study focused on a patient-centered outcome (Patient-RHDS/SF), we did not examine other important outcomes such as hospital readmission. Additionally, due to the small sample size, these results have limited generalizability and should be interpreted with caution. Last, we limited data collection to the day of hospital discharge; future studies might consider assessing discharge readiness throughout hospitalization.
