Interhospital Transfer of Intracerebral Hemorrhage Patients Undergoing Minimally Invasive Surgery: The Experience of a New York City Hospital System

OBJECTIVE

The impact of interhospital transfer (IHT) on outcomes of patients with intracerebral hemorrhage (ICH) has not been well studied. We seek to describe the protocolized IHT and systems of care approach of a New York City hospital system, where ICH patients undergoing minimally invasive surgery (MIS) are transferred to a dedicated ICH center.

METHODS

We retrospectively reviewed 100 consecutively admitted patients with spontaneous ICH. We gathered information on demographics, variables related to IHT, clinical and radiographic characteristics, and details about the clinical course and outpatient follow-up. We grouped patients into 2 cohorts: those admitted through IHT and those directly admitted through the emergency department. Primary outcome was good functional outcome at 6 months, defined as modified Rankin Scale score 0-3.

RESULTS

Of 100 patients, 89 underwent IHT and 11 were directly admitted. On multivariable analysis, there were no significant differences in 6-month functional outcome between the 2 cohorts. All transfers were managed by a system-wide transfer center and 24/7 hotline for neuroemergencies. An ICH-specific IHT protocol was followed, in which a neurointensivist provided recommendations for stabilizing patients for transfer. Average transfer time was 199.7 minutes and average distance travelled was 13.6 kilometers.

CONCLUSIONS

In our hospital system, a centralized approach to ICH management and a dedicated ICH center increased access to specialist services, including MIS. Most patients undergoing MIS were transferred from outside hospitals, which highlights the need for additional studies and descriptions of experiences to further elucidate the impact of and best protocols for the IHT of ICH patients.

A Multimodal Intervention to Improve the Quality and Safety of Interhospital Care Transitions for Nontraumatic Intracerebral and Subarachnoid Hemorrhage

BACKGROUND

Regionalization of care has increased interhospital transfers (IHTs) of nontraumatic intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) to specialized centers yet exposes patients to the latent risks inherent to IHT. The researchers examined how a multimodal quality improvement intervention affected quality and safety measures for patients with ICH or SAH exposed to IHT.

METHODS

Pre and post analyses of timeliness, effectiveness, and communication outcome measures were performed for patients transferred to an urban, academic center with nontraumatic ICH/SAH following implementation of a multimodal intervention. Intervention components included clinical practice guideline dissemination, IHT process redesign, electronic patient arrival notification, electronic imaging exchange, and electronic health record improvements. Three months of preintervention outcomes were compared to six months of postintervention outcomes to assess impact and sustainability of the intervention; t-tests and chi-square tests were used to compare continuous and proportional outcomes, respectively.

RESULTS

The IHT study population included 106 patients (37 preintervention, 69 postintervention). Significant improvements were observed in timeliness outcomes, including emergency department (ED) time to admission order (preintervention median: 66 minutes vs. postintervention: 33 minutes, p = 0.008), ED boarding time (preintervention median: 223 minutes vs. postintervention: 93 minutes, p = 0.001), and ED length of stay (preintervention median: 300 minutes vs. postintervention: 150 minutes, p ≤ 0.0001). Verbal communication between ED and neurocritical care clinicians prior to IHT improved from 40.0% preintervention to 90.9% postintervention.

CONCLUSION

Application of scripted quality improvement interventions as part of the IHT process is feasible and effective at improving the timeliness of care and communication of critical information in patients with nontraumatic ICH/SAH.

Interhospital transfer of pediatric neurosurgical patients

OBJECTIVE The purpose of this study was to describe patterns of transfer, resource utilization, and clinical outcomes associated with the interhospital transfer of pediatric neurosurgical patients. METHODS All consecutive, prospectively collected requests for interhospital patient transfer to the pediatric neurosurgical service at Texas Children's Hospital were retrospectively analyzed from October 2013 to September 2014. Demographic patient information, resource utilization, and outcomes were recorded and compared across predefined strata (low [< 5%], moderate [5%-30%], and high [> 30%]) of predicted probability of mortality using the Pediatric Risk of Mortality score. RESULTS Requests for pediatric neurosurgical care comprised 400 (3.7%) of a total of 10,833 calls. Of 400 transfer admissions, 96.5%, 2.8%, and 0.8% were in the low, moderate, and high mortality risk groups, respectively. The median age was 54 months, and 45% were female. The median transit time was 125 minutes. The majority of transfers were after-hours (69.8%); nearly a third occurred during the weekend (32.3%). The median intensive care unit stay for 103 patients was 3 days (range 1-269 days). Median length of hospital stay was 2 days (range 1-269 days). Ninety patients (22.5%) were discharged from the emergency room after transfer. Seventy-seven patients (19.3%) required neurosurgical intervention after transfer, with the majority requiring a cranial procedure (66.2%); 87.3% of patients were discharged home. CONCLUSIONS This study highlights patient characteristics, resource utilization, and outcomes among pediatric neurosurgical patients. Opportunities for quality improvement were identified in diagnosing and managing isolated skull fractures and neck pain after trauma.

Interhospital Transfer of Neurosurgical Patients to a High-Volume Tertiary Care Center: Opportunities for Improvement

BACKGROUND

Neurosurgical indications for patient transfer include absence of local or available neurosurgical coverage, subspecialty or interdisciplinary requirements, and family preference. Transfer of patients to regional centers will increase with further centralization of medical care.

OBJECTIVE

To report the transfer records of a large tertiary care center to identify trends, failures, and opportunities to improve interhospital transfer of neurosurgical patients.

METHODS

All consecutive, prospectively documented requests for interhospital patient transfer to the adult neurosurgical service of Emory University Hospitals were retrospectively identified from a centralized transfer center database for a 1-year study period.

RESULTS

Requests for neurosurgical care constituted 1323 of the 9087 calls (14.6%); 81.1% of these requests were accepted, and a total of 984 patients (74.4%) arrived at our institutions. Patients arrived from 133 unique facilities throughout a catchment area of 66 287 sq miles. Although the median travel time for transfer patients was 36 minutes, the median interval between the request and patient arrival was 4 hours 2 minutes. The most frequent diagnoses were intracranial hemorrhage (31.8%), subarachnoid hemorrhage (31.2%), and intracranial tumor (15.2%). The overall diagnostic error rate was 10.3%. Only 42.5% of patients underwent neurosurgical intervention, and 57 patients admitted to intensive care were immediately transitioned to a lower level of care.

CONCLUSION

Interhospital transfer requires a coordinated effort among hospital administrators, physicians, and staff to make complex decisions that govern this important and costly process. These data suggest common failures and numerous opportunities for improvement in transfer efficiency, diagnostic accuracy, triage, and resource allocation.
