Braude et al., 2017 (12)*Phase quality improvement project with stepwise interventions
Patients undergoing urology surgery aged > 65 yr and meeting 1 of the following criteria (130 patients):
1. Referred to POPS team
2. Emergency admission
3. Acute medical problem
4. Discharge-related problem
5. Length of stay > 7 d
Length of inpatient stay
Medical or surgical postoperative complications
30-d readmission rate
30-d mortality
Cancellation of surgery
Control: 112 (32 emergency)
Intervention: 130 (41 emergency)
Phase 1: before-and-after study with initiation of daily board rounds, weekly multidisciplinary meetings, and twice-weekly targeted geriatrician-led ward rounds.
Involved services: urology junior doctor, staff nurse, ward physiotherapy, and occupational therapy.
Phase 2: Plan-do-study-act cycles and qualitative staff surveys to create a geriatric surgical checklist that helps to standardize the board rounds, identify geriatric syndromes and facilitate targeted interventions, improve teamwork and equity of care, and reduce duplication of handovers.
Initially did not screen for frailty but in phase 2 through working groups created a checklist to identify those with geriatric syndrome risk factors. This was then embedded into routine clinical care using quality improvement.
Phase 1:
Length of stay ↓ 19% (4.9 [n = 124] v. 4.0 [n = 101]; p = 0.01)
Total postoperative complications decreased (24% [n = 101] v. 6% [n = 124] risk ratio 0.24, p = 0.001)
Fewer cancellations of surgery (10% [n = 112] v. 5% [n = 130]; p = 0.12) due to avoidance of medical problems as opposed to administrative reasons.
Subgroup analysis demonstrates no difference whether elective or emergency (p > 0.5).
30-d readmission (8% [n = 112] × 3% [n = 130]; p = 0.07)
Phase 2:
Staff understood their roles better in multidisciplinary meetings, had improved confidence with raising issues, reduced duplication of handovers and standardized identification of geriatric issues.
Five daily meetings were eliminated between nurses, disposition coordinators and allied health and as more people were joining the board rounds.
Board rounds remained at 30 min despite maintained POPS referrals, but cases changed to also include patients aged < 65 yr with more functional-related issues.
Koebrugge, et al., 2010 (13)*Prospective study using high-standard delirium protocol
No preintervention group; compared with existing literature
Patients aged > 65 yr undergoing elective and emergency aortoiliac surgery (24/110 emergency patients)
Excluded patients with Alzheimer disease or dementia
Postoperative delirium
Length of ICU stay
Length of hospital stay
Postoperative complications
Mortality
Control: none
Intervention (n = 107, 22 emergency)
Providing hearing aids or glasses for those impaired.
Photographs of relatives.
Calendars in every room.
Install familiar key points near all patients.
No preoperative pharmacologic treatment.
Does not screen for frailty. Instead uses Delirium Observation Scale of verbal and nonverbal behaviour 3 times daily. Geriatric consults for scores > 3. If deemed delirious after consultation, they would follow while in hospital and give advice to the surgical team daily, in addition to delirium work-up.
No standardized or specific pathway.
This study does not have emergency literature values to compare with, so not clear whether improved. But they did see improvements in the elective setting compared with previously published literature.
Patients with delirium were older (p = 0.01), had higher ASA scores (p = 0.01), lower diastolic blood pressure measurements (p = 0.03), and higher preoperative urea measurements (p = 0.02). They underwent longer operations (p = 0.01) and more often showed hemodynamic instability and blood loss (p < 0.01).
Previous literature values are in the 20%–30% range and include only elective patients.
Mortality rate 27.3% (emergency patients n = 22), and higher in patients developing delirium (p = 0.03).
59% of patients developed delirium after emergency surgery (n = 22), especially after laparotomy (compared with endovascular surgery) (p = 0.01).
Delirious patients had longer ICU stay (p = 0.01), had longer length of stay (p < 0.01), and developed more complications (p < 0.01).
Relative risk factors for delirium: advanced age and emergency surgery.
Bakker et al., 2014 (14)*Before–after study
Elective and emergency surgery
Patients > 70 yr and frail with expected length of stay > 48 h
Were able to begin intervening at least 48 h before admission
Excluded: delirium at admission, refusal, logistic issues
Primary:
Incidence of delirium
Cognitive decline, and decline in ADLs during hospital stay
Secondary:
ADL performance at 3 mo postdischarge
Readmission caregiver burden
Control:
191 (120 surgical, 13% emergency)
Intervention:
195 (121 surgical, 22% emergency)
CareWell in Hospital program:
Frailty review by a nurse, geriatric nurse, and then geriatrician (medication review and patient/family interviews), followed by comprehensive geriatric assessment and CareWell team verbal and written recommendations to the medical team, carefully categorized for clarity. The patient is followed closely while in hospital as part of a comprehensive geriatric assessment.
Dynamic patient care via weekly multidisciplinary meetings with the entire health care team. Various stimulating activities with volunteers. Educational sessions to the nurses and physicians, and provision of continuous coaching.
Screening for frailty but unclear how and if standardized.
CareWell program: proactive and intensive support by CareWell geriatrics team for older, frail patients and increased awareness among nurses and physicians + team of volunteers to offer cognitively and physically stimulating activities.
Delirium and functional decline were highest among the surgical patients, but this was not statistically significant between before and after intervention groups.
Significant improvement in ADLs at 3 mo and significant decrease in burden of care felt by informal caregivers.
Surgical v. medical, not elective v. emergency.
Surgical patients:
Delirium: 13% (n = 120) v. 12% (n = 121), p = 0.828
Cognitive decline: 19% (n = 84) v. 14% (n = 96), p = 0.316
Physical decline: 41% (n = 80) v. 61% (n = 98), p = 0.008
ADLs at 3 mo: 7.9% (n = 62) v. 9.5% (n = 81), p = 0.035
Readmission < 1 mo: 11% (n = 120) v. 14% (n = 121), p = 0.464
Caregiver burden of care: 3.1% (n = 19) v. 1.9% (n = 26), p = 0.126)
Engelhardt et al., 2018 (15)*Before–after study
Patients aged > 65 yr who screened positive for frailty and emergency and nonoperative general surgery/trauma patients
Length of stay, loss of independence (decline in function or mobility, increased care needs at home, or discharge to nonhome destination), 30-d readmission ratesControl:
11 emergency surgical
Intervention:
59 emergency surgical
Assessed frailty using trauma-specific and emergency general surgery–specific frailty indices.
Discussions with the team, patient, and family about length of stay and disposition goals were held and documented.
Early hospitalist consultation used to address complex medical needs.
Expedited allied health involvement if increased risk of falls and difficulty with ADLs.
Created geriatric-specific admission order sets.
Standardized multitiered postdischarge follow-up schedule.
Length of stay: 9–6 d (p = 0.4)
Readmissions decreased: 36.4%–10.2% (p = 0.02)
Loss of independence: 100%–60% (p = 0.01)
By prioritizing frail patients, other nonfrail geriatric patients may have had delays in their evaluation and thus worsened length of stay, loss of independence, or readmissions. However, these outcomes were not significantly different before or after the intervention.
