Abstract
BACKGROUND While clinical guidelines provide a framework for hospital management of spontaneous intracerebral hemorrhage (ICH), variation in the resource utilization and costs of these services exist. OBJECTIVES Perform a systematic literature review to assess the evidence on hospital resource utilization and costs associated with management of adult ICH patients, as well as identify factors that impact variation in such hospital resource utilization and costs, regarding clinical characteristics and delivery of services. METHODS A systematic literature review was performed using PubMed, Cochrane Central Register of Controlled Trials, and Ovid MEDLINE(R) 1946 to Present. Articles were assessed against inclusion and exclusion criteria. Study design, ICH sample size, population, setting, objective, hospital characteristics, hospital resource utilization and cost data, and main study findings were abstracted. RESULTS 43 studies met the inclusion criteria. Pertinent clinical characteristics that increased hospital resource use included presence of comorbidities and baseline ICH severity. Aspects of service delivery that greatly impacted hospital resource consumption included ICU length of stay and performance of surgical procedures and intensive care procedures. CONCLUSION Hospital resource utilization and costs for ICH patients were high and differed widely across studies. Making concrete conclusions on hospital resources and costs for ICH care was constrained given methodological and patient variation in the studies. Future research should evaluate the long-term cost-effectiveness of ICH treatment interventions and use specific economic evaluation guidelines and common data elements to mitigate study variation.

Abstract
INTRODUCTION The practice of platelet transfusion to mitigate the deleterious effects of antiplatelet agents on spontaneous intracerebral hemorrhage (ICH) remains common. However, the effect of antiplatelet agents on patients with ICH is still controversial and transfusing platelets is not without risk. We performed a meta-analysis in order to determine the effect of platelet transfusion on antiplatelet agent associated ICH. METHODS We queried PubMed, Embase, and Scopus databases to identify cohort studies, case-control studies, and randomized control trials. Study quality was graded by the Newcastle-Ottawa Scale and Cochrane Risk of Bias tool, as appropriate. Outcomes of interest included functional independence as measured by the modified Rankin Scale and mortality. We compared patients with antiplatelet agent associated ICH who received platelet transfusion to those that did not. RESULTS We identified 625 articles. After reviewing 44 full text articles, 5 were deemed appropriate for meta-analysis, including 4 cohort studies and one randomized control trial. Considerable heterogeneity was present among the studies (I(2) > 81% for all analyses). We did not find a significant effect of platelet transfusions on functional independence (Odds Ratio [OR] 1.3, 95% CI.0.45-3.9) or mortality (OR 0.58, 95% Confidence Interval [CI] 0.12-2.6). CONCLUSION We found no evidence for an effect of platelet transfusions on functional independence or mortality following antiplatelet associated ICH. More randomized trials are needed to evaluate platelet transfusion in patients with ICH and proven reduced platelet activity or those requiring neurosurgical intervention.

Abstract
BACKGROUND Platelet transfusion after acute spontaneous primary intracerebral haemorrhage in people taking antiplatelet therapy might reduce death or dependence by reducing the extent of the haemorrhage. We aimed to investigate whether platelet transfusion with standard care, compared with standard care alone, reduced death or dependence after intracerebral haemorrhage associated with antiplatelet therapy use. METHODS We did this multicentre, open-label, masked-endpoint, randomised trial at 60 hospitals in the Netherlands, UK, and France. We enrolled adults within 6 h of supratentorial intracerebral haemorrhage symptom onset if they had used antiplatelet therapy for at least 7 days beforehand and had a Glasgow Coma Scale score of at least 8. With use of a secure web-based system that concealed allocation and used biased coin randomisation, study collaborators randomly assigned participants (1:1; stratified by hospital and type of antiplatelet therapy) to receive either standard care or standard care with platelet transfusion within 90 min of diagnostic brain imaging. Participants and local investigators giving interventions were not masked to treatment allocation, but allocation was concealed from outcome assessors and investigators analysing data. The primary outcome was shift towards death or dependence rated on the modified Rankin Scale (mRS) at 3 months, and analysed by ordinal logistic regression, adjusted for stratification variables and the Intracerebral Haemorrhage Score. The primary analysis was done in the intention-to-treat population and safety analyses were done in the intention-to-treat and as-treated populations. This trial is registered with the Netherlands Trial Register, number NTR1303, and is now closed. FINDINGS Between Feb 4, 2009, and Oct 8, 2015, 41 sites enrolled 190 participants. 97 participants were randomly assigned to platelet transfusion and 93 to standard care. The odds of death or dependence at 3 months were higher in the platelet transfusion group than in the standard care group (adjusted common odds ratio 2.05, 95% CI 1.18-3.56; p=0.0114). 40 (42%) participants who received platelet transfusion had a serious adverse event during their hospital stay, as did 28 (29%) who received standard care. 23 (24%) participants assigned to platelet transfusion and 16 (17%) assigned to standard care died during hospital stay. INTERPRETATION Platelet transfusion seems inferior to standard care for people taking antiplatelet therapy before intracerebral haemorrhage. Platelet transfusion cannot be recommended for this indication in clinical practice.

Abstract
BACKGROUND Use of antiplatelet therapy shortly before stroke due to spontaneous primary intracerebral haemorrhage (ICH) is associated with higher case fatality in comparison to ICH without prior antithrombotic drug use. The PlAtelet Transfusion in Cerebral Haemorrhage (PATCH) trial aimed to assess the effect of platelet transfusion in patients presenting with ICH while using antiplatelet therapy. The main hypothesis of PATCH was that platelet transfusion would reduce death or dependence by reducing ICH growth. METHODS/DESIGN PATCH was a multicentre prospective, randomised, open, blinded endpoint (PROBE) parallel group trial, conducted at 60 hospitals in The Netherlands, Scotland and France. Forty-one sites enrolled 190 patients with spontaneous supratentorial ICH aged ≥18 years, who had used antiplatelet therapy for ≥7 days preceding ICH, if Glasgow Coma Scale was ≥8. Participants were randomised (1:1, with a secure web-based system using permuted blocks, stratified by study centre and type of antiplatelet therapy pre-ICH) to receive either platelet transfusion within 6 hours of symptom onset and 90 minutes of diagnostic brain imaging, or standard care without platelet transfusion. The primary outcome was modified Rankin Scale (mRS) score assessed blind to treatment allocation at 3 months after ICH. Planned secondary outcomes included ICH growth on brain imaging performed approximately 24 hours after randomisation, survival at 3 months, disability at 3 months scored using the Amsterdam Medical Centre linear disability score, heterogeneity of treatment effect on mRS and ICH growth according to presence of the computed tomography angiography spot sign, causes of poor outcome, and cost-effectiveness. Safety outcomes were transfusion reactions, thromboembolic complications, and serious adverse events occurring during hospitalisation. This statistical analysis plan was written without knowledge of the unblinded data. TRIAL REGISTRATION The trial was registered with the Netherlands Trial Register on 29 April 2008 ( NTR1303 ).

Journal of Neurosurgery. 2013;118((1):):94-103.
Abstract
OBJECT The authors evaluated the effects of acetylsalicylic acid (ASA) usage and transfusion of previously frozen apheresis platelets on postoperative hemorrhage, activities of daily living (ADL) score, and mortality rate in patients with acute hypertensive basal ganglia hemorrhage undergoing craniotomy. METHODS This was a prospective, double-blind, parallel, randomized controlled trial in patients with acute hypertensive basal ganglia hemorrhage, who had either not received ASA therapy (control) or received ASA therapy. The patients who received ASA therapy were divided according to the results of a platelet aggregation test into ASA-resistant, ASA-semiresponsive, and ASA-sensitive groups. All patients required an emergency craniotomy for hematoma removal after hospitalization. The patients who were sensitive to ASA were randomized to receive one of the following transfusion regimens of previously frozen apheresis platelets: no transfusion, 1 therapeutic dose before surgery, or 2 therapeutic doses (1 before surgery and 1 after 24 hours of hospitalization). The postoperative hemorrhage rate and the average postoperative hemorrhage volume were recorded and the ADL scores and mortality rate were measured during a 6-month follow-up period. RESULTS The rate of postoperative hemorrhage, average postoperative hemorrhage volume, and mortality rate were significantly higher in the ASA-sensitive patients who received ASA therapy compared with patients who did not receive ASA therapy (all p < 0.005). The ADL scores were grouped into different grades and the number of cases in the lower grades was higher and the overall scores were poorer in patients who received ASA therapy compared with those who did not (all p < 0.005). After transfusion of previously frozen apheresis platelets, the postoperative hemorrhage rate, average postoperative hemorrhage volume, and mortality rate of the ASA-sensitive patients were significantly lowered (all p < 0.005), and the ADL scores and their classification level were better than those of patients who did not undergo transfusion (all p < 0.005). CONCLUSIONS Transfusion of previously frozen apheresis platelets reduces the rate of postoperative hemorrhage, average postoperative hemorrhage volume, disability rate, and mortality rate in ASA-sensitive patients with acute hypertensive basal ganglia hemorrhage undergoing craniotomy.

PATCH: platelet transfusion in cerebral haemorrhage: study protocol for a multicentre, randomised, controlled trial
de Gans K, de Haan RJ, Majoie CB, Koopman MM, Brand A, Dijkgraaf MG, Vermeulen M, Roos YB, PATCH Investigators
BMC Neurology. 2010;10:19
Abstract
BACKGROUND Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect. METHODS/DESIGN The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included. DISCUSSION To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.
