Evaluation of a multicomponent intervention to shorten thrombolytic door-to-needle time in stroke patients in China (MISSION): A cluster-randomized controlled trial.

ABSTRACT:

Background

Rapid intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) is crucial for improving outcomes. However, few randomized trials of interventions aimed at reducing in-hospital delay have been carried out in China. We aimed to evaluate the effect of a multicomponent intervention on thrombolytic door-to-needle time (DNT) of AIS patients via video teleconference based on the Behavior Change Wheel (BCW) method.

Methods and findings

This cluster-randomized trial, conducted between January 1, 2019 and December 31, 2019, randomly allocated 22 hospitals equally to PEITEM (Persuasion Environment reconstruction Incentivization Training Education Modeling) intervention or routine care plus stroke registry and subsequently enrolled 1,634 AIS patients receiving IVT within 4.5 hours upon stroke onset from participant hospitals. The PEITEM group received a 1-year PEITEM 6-component intervention based on the behavioral theory monthly via video teleconference. The primary outcome was the proportion of patients with a DNT of 60 minutes or less. A total of 987 patients participated in the PEITEM group (mean age, 69 years; female, 411 [41.6%]) and 647 patients in the control group (mean age, 70 years; female, 238 [36.8%]). Of all participants, the proportion of DNT ≤60 minutes in the PEITEM group was higher than in the control group (82.0% versus 73.3%; adjusted odds ratio, 1.77; 95% confidence interval (CI), 1.17 to 2.70; ICC, 0.04; P = 0.007). Among secondary outcomes, the average DNT was 43 minutes in the PEITEM group and 50 minutes in the control group (adjusted mean difference: -8.83; 95% CI, -14.03 to -3.64; ICC, 0.12; P = 0.001). Favorable functional outcome (score of 0 to 1 on the modified Rankin scale (mRS)) was achieved in 55.6% patients of the PEITEM group and 50.4% of the control group (adjusted odds ratio, 1.38; 95% CI, 1.00 to 1.90; ICC, 0.01; P = 0.049). Main study limitations include non-blinding of clinicians, and that specific interventions component responsible for the observed changes could not be determined.

Conclusions

The teleconference-delivered PEITEM intervention resulted in a moderate but clinically relevant shorter DNT and better functional outcome in AIS patients receiving IVT.

Project description:Importance:Earlier administration of intravenous tissue plasminogen activator (tPA) in acute ischemic stroke is associated with reduced mortality by the time of hospital discharge and better functional outcomes at 3 months. However, it remains unclear whether shorter door-to-needle times translate into better long-term outcomes.Objective:To examine whether shorter door-to-needle times with intravenous tPA for acute ischemic stroke are associated with improved long-term outcomes.Design, setting, and participants:This retrospective cohort study included Medicare beneficiaries aged 65 years or older who were treated for acute ischemic stroke with intravenous tPA within 4.5 hours from the time they were last known to be well at Get With The Guidelines-Stroke participating hospitals between January 1, 2006, and December 31, 2016, with 1-year follow-up through December 31, 2017.Exposures:Door-to-needle times for intravenous tPA.Main outcomes and measures:The primary outcomes were 1-year all-cause mortality, all-cause readmission, and the composite of all-cause mortality or readmission.Results:Among the 61?426 patients treated with tPA within 4.5 hours, the median age was 80 years and 43.5% were male. The median door-to-needle time was 65 minutes (interquartile range, 49-88 minutes). The 48?666 patients (79.2%) who were treated with tPA and had door-to-needle times of longer than 45 minutes, compared with those treated within 45 minutes, had significantly higher all-cause mortality (35.0% vs 30.8%, respectively; adjusted HR, 1.13 [95% CI, 1.09-1.18]), higher all-cause readmission (40.8% vs 38.4%; adjusted HR, 1.08 [95% CI, 1.05-1.12]), and higher all-cause mortality or readmission (56.0% vs 52.1%; adjusted HR, 1.09 [95% CI, 1.06-1.12]). The 34?367 patients (55.9%) who were treated with tPA and had door-to-needle times of longer than 60 minutes, compared with those treated within 60 minutes, had significantly higher all-cause mortality (35.8% vs 32.1%, respectively; adjusted hazard ratio [HR], 1.11 [95% CI, 1.07-1.14]), higher all-cause readmission (41.3% vs 39.1%; adjusted HR, 1.07 [95% CI, 1.04-1.10]), and higher all-cause mortality or readmission (56.8% vs 53.1%; adjusted HR, 1.08 [95% CI, 1.05-1.10]). Every 15-minute increase in door-to-needle times was significantly associated with higher all-cause mortality (adjusted HR, 1.04 [95% CI, 1.02-1.05]) within 90 minutes after hospital arrival, but not after 90 minutes (adjusted HR, 1.01 [95% CI, 0.99-1.03]), higher all-cause readmission (adjusted HR, 1.02; 95% CI, 1.01-1.03), and higher all-cause mortality or readmission (adjusted HR, 1.02 [95% CI, 1.01-1.03]).Conclusions and relevance:Among patients aged 65 years or older with acute ischemic stroke who were treated with tissue plasminogen activator, shorter door-to-needle times were associated with lower all-cause mortality and lower all-cause readmission at 1 year. These findings support efforts to shorten time to thrombolytic therapy.

Project description:BackgroundExisting data and clinical trials could not determine whether faster intravenous thrombolytic therapy (IVT) translates into better long-term functional outcomes after acute ischemic stroke among those treated with endovascular thrombectomy (EVT). Patient-level national data can provide the required large population to study the associations between earlier IVT, versus later, with longitudinal functional outcomes and mortality in patients receiving IVT+EVT combined treatment.MethodsThis cohort study included older US patients (age ≥65 years) who received IVT within 4.5 hours or EVT within 7 hours after acute ischemic stroke using the linked 2015 to 2018 Get With The Guidelines-Stroke and Medicare database (38 913 treated with IVT only and 3946 with IVT+EVT). Primary outcome was home time, a patient-prioritized functional outcome. Secondary outcomes included all-cause mortality in 1 year. Multivariate logistic regression and Cox proportional hazards models were used to evaluate the associations between door-to-needle (DTN) times and outcomes.ResultsAmong patients treated with IVT+EVT, after adjusting for patient and hospital factors, including onset-to-EVT times, each 15-minute increase in DTN times for IVT was associated with significantly higher odds of zero home time in a year (never discharged to home) (adjusted odds ratio, 1.12 [95% CI, 1.06-1.19]), less home time among those discharged to home (adjusted odds ratio, 0.93 per 1% of 365 days [95% CI, 0.89-0.98]), and higher all-cause mortality (adjusted hazard ratio, 1.07 [95% CI, 1.02-1.11]). These associations were also statistically significant among patients treated with IVT but at a modest degree (adjusted odds ratio, 1.04 for zero home time, 0.96 per 1% home time for those discharged to home, and adjusted hazard ratio 1.03 for mortality). In the secondary analysis where the IVT+EVT group was compared with 3704 patients treated with EVT only, shorter DTN times (≤60, 45, and 30 minutes) achieved incrementally more home time in a year, and more modified Rankin Scale 0 to 2 at discharge (22.3%, 23.4%, and 25.0%, respectively) versus EVT only (16.4%, P<0.001 for each). The benefit dissipated with DTN>60 minutes.ConclusionsAmong older patients with stroke treated with either IVT only or IVT+EVT, shorter DTN times are associated with better long-term functional outcomes and lower mortality. These findings support further efforts to accelerate thrombolytic administration in all eligible patients, including EVT candidates.

Project description:Better outcomes are obtained with stroke thrombolysis the more rapidly it is given, both in terms of the patient's level of functional ability and also mortality. Current UK performance targets (outside London) aim for a time of 45 minutes or less. Thrombolysis pathways involve multidisciplinary working across departmental boundaries as well as senior level decision making. Our system used telemedicine out of hours adding additional complexity to the pathway. The initial planning stages started by auditing current practice and mapping the existing pathway. The figures for door to needle times were held on a database on the stroke unit and collected in detail for the purposes of national reporting. The pathway was mapped by combining personal experience of working within the stroke service with the experiences of the general medical registrars who worked the system out of hours. The initial action was to present this information throughout the hospital at departmental meetings. Opinions were canvassed at these meetings on where the biggest barriers were within the pathway and how we could address them. An awareness campaign was held by advertising over the intranet. An intervention comprising the following elements was introduced over the period of a year: introduction of an ambulance pre-alert, revision of the existing pathway, and education to all those involved in thrombolysis. The cases where particularly long delays were noted were audited in more depth to identify barriers to flow through the system. This was reported in ward meetings for staff to contribute experience and to offer solutions. We went to commissioning group meetings to gain the support of the local ambulance service, and talked to A&E seniors about the project and the ways in which they could help. Median times were calculated from a stroke database. There was a fall in median door to needle time of 65.5 to 49 minutes over a period of 18 months. A complex intervention to improve door to needle time can and did produce good results with a reduction in times to within the London performance standards of care. The efficacy could be improved with an increased staffing level and provision of a formal setting within which to discuss changes and to keep up the momentum of change.

Project description:OBJECTIVE:The current study aimed to evaluate the effects of a multi-component in-hospital intervention on the door-to-needle time for intravenous thrombolysis in acute ischaemic stroke. DESIGN:This study was a post hoc analysis of door-to-needle time data from a cluster-randomised controlled trial testing an intervention to boost intravenous thrombolysis implementation. SETTING:The study was conducted among 20 hospitals from three Australian states. PARTICIPANT:Eligible hospitals had a Stroke Care Unit or staffing equivalent to a stroke physician and a nurse, and were in the early stages of implementing thrombolysis. INTERVENTION:The intervention was multifaceted and developed using the behaviour change wheel and informed by breakthrough collaborative methodology using components of the health behaviour change wheel. PRIMARY AND SECONDARY OUTCOME MEASURES:The primary outcome for this analysis was door-to-needle time for thrombolysis and secondary outcome was the proportion of patients received thrombolysis within 60?min of hospital arrival. RESULTS:The intervention versus control difference in the door-to-needle times was non-significant overall nor significant by hospital classification. To provide additional context for the findings, we also evaluated the results within intervention and control hospitals. During the active-intervention period, the intervention hospitals showed a significant decrease in the door-to-needle time of 9.25?min (95%?CI: -16.93 to 1.57), but during the post-intervention period, the result was not significant. During the active intervention period, control hospitals also showed a significant decrease in the door-to-needle time of 5.26?min (95%?CI: -8.37 to -2.14) and during the post-intervention period, this trend continued with a decrease of 12.13?min (95%?CI: -17.44 to 6.81). CONCLUSION:Across these primary stroke care centres in Australia, a secular trend towards shorter door-to-needle times across both intervention and control hospitals was evident, however the TIPS (Thrombolysis ImPlementation in Stroke) intervention showed no overall effect on door-to-needle times in the randomised comparison.
