Eastern Health Partnership

Our partnership with Eastern Health drives research to improve patient safety outcomes and patient experience of healthcare. The partnership between Eastern Health and Deakin University commenced in 1999 and our research spans acute, subacute, community and residential care settings. Our work informs strategic directions for clinical practice, education, research and healthcare policy development.

The Eastern Health partnership was established in 1999. Eastern Health has over 1500 beds in its seven hospitals and four residential aged care facilities, and over 4,500 nurses and midwives. Eastern Health delivers clinical services to more than 800,000 people in a catchment area spanning 2816 square kilometres across 65 sites in 21 locations. One in four patients originate from non-English speaking countries, and there are 92 nationalities represented across the Eastern Health workforce.

Broad areas of research:

Clinical deterioration

Acute care readmissions from subacute care

Background

Patients who need inpatient rehabilitation after initial acute hospital care for illness or surgery frequently have a complex journey through different healthcare sectors. For the majority of patients, rehabilitation requires moving from an acute care hospital to a stand-alone hospital where rehabilitation services are provided. If their condition deteriorates during rehabilitation, they will be transferred to an acute care hospital for further assessment and care.

Aim/objective/s

To describe characteristics and outcomes of emergency interhospital transfers from

subacute to acute hospital care.

Method

Prospective case-time-control study conducted in 21 wards in eight subacute healthcare facilities from five health services in Victoria, Australia. Cases were patients with an emergency interhospital transfer from subacute to acute hospital care. For every case, two inpatients from the same subacute care ward on the same day of emergency transfer were randomly selected as controls. Admission episode was the unit of measurement and data were collected prospectively.

Results

Data were collected for 603 transfers in 557 patients and 1160 control patients. Unplanned emergency transfers from subacute to acute care hospitals were:

  • associated with poor outcomes: 81% of transferred patients were readmitted to acute care with a median readmission length of stay (LOS) of 8 days.(3) Compared to control patients, transfer patients had higher in-hospital mortality (14.9% vs 2.3%, p<0.001); and more unplanned intensive care unit (ICU) admission(s) (4.3% vs 0.5%, p<0.001) and rapid response team (RRT) call(s) (20.4% vs 7.5%, p<0.001) during their health service stay.1  Compared to patients for full resuscitation, patients with not-for-CPR or limitations of medical treatment orders were more likely to have rapid response team calls during acute care readmission or to die during hospitalisation. Patients who were not-for-CPR were less likely to be readmitted to acute care and more likely to return to subacute care than patients with  limitations of medical treatment orders or for full resuscitation.2
  • resource intensive: 75% of transfers were by emergency ambulance;1 and 76% of transferred patients required emergency department (ED) care with a median ED LOS of 6 hours.1 One in eleven transfers (8.9%) occurred within one day of subacute care admission.3
  • predictable: when adjusted for age and health service, ³2 vital sign abnormalities in subacute care (Adjusted Odds Ratio (AOR)=8.7, 95%CI: 6.3-12.0, p<0.001) and clinical deterioration events (unplanned ICU admission, RRT or cardiac arrest team calls) during the initial acute care admission (AOR=1.4, 95%CI: 1.0-1.9, p=0.029) increased transfer risk (4, 5); and transfer risk decreased with higher functional independence (AOR=0.99, 95% CI: 0.98-0.99, p=0.009).1,4

Conclusion

Patients who require an emergency interhospital transfer from subacute to acute

hospital care have hospital admission rates and in-hospital mortality. Clinical instability during the first acute care admission (serious adverse events or increased surveillance) may prompt reassessment of patient suitability for movement to a separate subacute care hospital. Serious adverse events in acute care should be a key consideration in decisions about the location of subacute care delivery. During subacute care, 15.7% of cases had vital signs fulfilling organisational rapid response team activation criteria, yet missed rapid response team activations were common suggesting that further consideration of the criteria and strategies to optimise recognition and response to clinical deterioration in subacute care are needed.

Reducing unplanned hospital readmissions

Background

Unplanned hospital readmissions may result from exacerbation of underlying disease or potentially preventable failure of care provision. For patients and carers, unplanned hospital readmissions are distressing, inconvenient and increase risk of iatrogenic harm such as falls, medication errors, delirium, or poor hydration and nutrition. For the healthcare system, unplanned hospital readmissions are costly and result in potentially avoidable resource utilisation.

Aim/objective/s

To gain an understanding of the factors associated with unplanned hospital readmission ≤28 days of acute care discharge from a major Australian health service; to explore the reasons for unplanned hospital readmissions ≤1 day of acute care discharge, and determine what proportion of such unplanned hospital readmissions were potentially preventable; and To understand from a patient and carer perspective, what features of the discharge process could be improved to avoid early unplanned hospital readmission (≤72 hours of acute care discharge) and what elements of discharge planning could have enhanced the discharge experience.

Method

Program of research conducted at Eastern Health:

  • A retrospective study of 20,575 acute care discharges ≤ 28 days of discharge.1
  • A medical record audit of 170 unplanned hospital readmissions ≤1 day.2
  • Interviews with 29 patients and 7 carers who experienced an unplanned hospital readmission within 3 days of acute care discharge.3

Results

  • The unplanned readmission rate was 7.4% (n = 1528) and 11.1% of readmitted patients were returned within 1 day. The factors associated with increased risk of unplanned readmission in _28 days for all patients were age ³65 years, emergency index admission, Charlson comorbidity index >1, presence of chronic disease or complications during the index admission, index admission length of stay (LOS) >2 days, hospital admission(s) or emergency department (ED) attendance(s) in the 6 months preceding the index admission. However, the factors associated with increased risk of increased risk of unplanned readmission≤28 days changed with each patient group (adult medical, adult surgical, obstetric and paediatric).1
  • Unplanned readmissions ≤1 day were more likely in paediatric patients; index discharges on weekends, from short stay unit (SSU) or against health professional advice; or when the readmission was for a similar Diagnosis Related Group. The significant predictors of unplanned readmission ≤1 day were index discharge against advice or from SSU, and 1–5 hospital admissions in the 6 months preceding index admission. Only 11.7% of unplanned readmissions ≤1 day were preventable. The median patient age was 57 years and comorbidities were uncommon (3.1%). Most patients (94.4%) lived at home and with others (78.9%). Friday was the most common day of index discharge (17.3%) and Saturday was the most common day of unplanned readmission (19.1%). The majority (94.4%) of readmissions were via the emergency department: 58.5% were for a like diagnosis and pain was the most common reason for readmission.2
  • Patient and carer interviews resulted in five themes: ‘experiences of care’, ‘hearing and being heard’, ‘what’s wrong with me’, ‘not just about me’ and ‘all about going home’. There was considerable variability in patients’ and carers’ experiences of hospital care, discharge processes and early unplanned hospital readmission. Features of the discharge process that could be improved to potentially avoid early unplanned hospital readmission were better communication, optimal clinical care including ensuring readiness for discharge and shared decision-making regarding discharge timing and goals on returning home. The discharge experience could have been enhanced by improved communication between patients (and carers) and the healthcare team, not rushing the discharge process and a more coordinated approach to patient transport home from hospital.3

Conclusion

There were specific patient and index admission characteristics associated with increased risk of unplanned readmission in _28 days; however, these characteristics varied between patient groups, highlighting the need for tailored interventions. Advanced age, significant comorbidities and social isolation did not feature in patients with an unplanned readmission ≤1 day. One quarter of patients were discharged on a Friday or weekend, one quarter of readmissions occurred on a weekend, and pain was the most common reason for readmission raising issues about access to services and weekend discharge planning. The discharge process is complex and effective communication, shared decision-making and carer engagement in optimising hospital discharge and reducing early unplanned hospital readmissions is vital to reducing unplanned hospital readmissions.
