Increasing patient flow through neurosurgical critical care: the Leeds Improvement Method

Interventions to improve patient admission and discharge practices in adult intensive care units: A systematic review

OBJECTIVES

To identify and synthesise interventions and implementation strategies to optimise patient flow, addressing admission delays, discharge delays, and after-hours discharges in adult intensive care units.

METHODS

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines. Five electronic databases, including CINAHL, PubMed, Emcare, Scopus, and the Cochrane Library, were searched from 2007 to 2023 to identify articles describing interventions to enhance patient flow practices in adult intensive care units. The Critical Appraisal Skills Program (CASP) tool assessed the methodological quality of the included studies. All data was synthesised using a narrative approach.

SETTING

Adult intensive care units.

RESULTS

Eight studies met the inclusion criteria, mainly comprising quality improvement projects (n = 3) or before-and-after studies (n = 4). Intervention types included changing workflow processes, introducing decision support tools, publishing quality indicator data, utilising outreach nursing services, and promoting multidisciplinary communication. Various implementation strategies were used, including one-on-one training, in-person knowledge transfer, digital communication, and digital data synthesis and display. Most studies (n = 6) reported a significant improvement in at least one intensive care process-related outcome, although fewer studies specifically reported improvements in admission delays (0/0), discharge delays (1/2), and after-hours discharge (2/4). Two out of six studies reported significant improvements in patient-related outcomes after implementing the intervention.

CONCLUSION

Organisational-level strategies, such as protocols and alert systems, were frequently employed to improve patient flow within ICUs, while healthcare professional-level strategies to enhance communication were less commonly used. While most studies improved ICU processes, only half succeeded in significantly reducing discharge delays and/or after-hours discharges, and only a third reported improved patient outcomes, highlighting the need for more effective interventions.

IMPLICATIONS FOR CLINICAL PRACTICE

The findings of this review can guide the development of evidence-based, targeted, and tailored interventions aimed at improving patient and organisational outcomes.

Effect of neurosurgical high observation beds (HOBs) on service provision: a single-centre experience and cost analysis

OBJECTIVE

To evaluate the effect of level 1, high observation beds (HOBs) compared with high dependency unit (HDU) and neurosurgical intensive care unit (NICU) admission on service provision, such as cancelled operations, and healthcare costs.

METHODS

A retrospective, observational, single-centre cross-sectional study at a single, large UK neurosurgical centre. All adult patients admitted to neurosurgical HOBs between December 2021 and July 2022 were included. The list of cancelled procedures was collected from 2019 to 2022. To evaluate the impact of admission of eligible patients to HOBs, the total bed days, cost per bed day, number of admissions and cost per admission were obtained for all clinical areas the financial years 2019/2020 and 2021/2022.

RESULTS

307 patients were included in the study: 59.7% of HOBs admissions were elective and 37.7% were acute; admissions were for cranial procedures or conservative treatment (64.8%), spinal (32.6%) or other (2.6%). Following admission, 73.3% of patients were stepped down to the ward prior to discharge home. Only seven patients required escalation to level-2 or level-3 care. Overall, 97% of all HOBs patients were discharged home at the end of hospital stay. Occupancy rate was 90.4%.The cost of bed day increased from ward, level 0 (£384), then level 1 (£376), to level 2 (£787-1211) and to level 3 (£1628). From 2019 to 2021, 558 operations had been cancelled, and 140 (37.8%) of 370 were estimated to have been potentially avoided by HOBs admissions due to conflict of scheduling, ward bed capacity and critical care bed capacity. In addition, a minimum total expenditure due to cancelled operations was estimated at £22 923.50 yearly on average.

CONCLUSION

This study recognises HOBs growing role in the management of acutely unwell patients in ward-based environments. While recognising the associated challenges, this study highlighted the potential in reducing healthcare costs. Further studies should evaluate the impact and limitations of HOBs on patients' recovery and outcomes, compared to HDU and NICU.

Venous Sinus Stenting: Safety and Health Care Resource Evaluation for Optimal Recovery in an Evolving Health Care Environment

BACKGROUND

Increasing evidence supports the effectiveness of venous sinus stenting (VSS) with favorable outcomes, safety, and expenses compared with shunting for idiopathic intracranial hypertension. Yet, no evidence is available regarding optimal postoperative recovery, which has increasing importance with the burdens on health care imposed by the coronavirus disease 2019 pandemic. We examined adverse events and costs after VSS and propose an optimal recovery pathway to maximize patient safety and reduce stress on health care resources.

METHODS

A retrospective review was undertaken of elective VSS operations performed from May 2008 to August 2021 at a single institution. Primary data included hospital length of stay, intensive care unit (ICU) length of stay, adverse events, need for ICU interventions, and hospital costs.

RESULTS

Fifty-three patients (98.1% female) met the inclusion criteria. Of these patients, 51 (96.2%) were discharged on postoperative day (POD) 1 and 2 patients were discharged on POD 2. Both patients discharged on POD 2 remained because of groin hematomas from femoral artery access. There were no major complications or care that required an ICU. Eight patients (15.1%) were lateralized to other ICUs or remained in a postanesthesia care unit because the neurosciences ICU was above capacity. Total estimated cost for initial recovery day in a neurosciences ICU room was $2361 versus $882 for a neurosurgery/neurology ward room. In our cohort, ward convalescence would save an estimated $79,866 for bed placement alone and increase ICU bed availability.

CONCLUSIONS

Our findings reaffirm the safety of VSS. These patients should recover on a neurosurgery/neurology ward, which would save health care costs and increase ICU bed availability.
