Return to Work of Patients Treated With Spinal Cord Stimulation for Chronic Pain: A Systematic Review and Meta-Analysis.

BACKGROUND: Chronic pain has a substantial negative impact on work-related outcomes, which underscores the importance of interventions to reduce the burden. Spinal cord stimulation (SCS) efficiently causes pain relief in specific chronic pain syndromes. The aim of this review was to identify and summarize evidence on returning to work in patients with chronic pain treated with SCS. MATERIALS AND METHODS: A systematic literature review was performed including studies from PubMed, EMBASE, SCOPUS, and Web of Science (up till October 2017). Risk of bias was assessed using a modified version of the Downs & Black checklist. Where possible, we pooled data using random effects meta-analysis. The study protocol was registered prior to initiation of the review process (PROSPERO CRD42017077803). RESULTS: Fifteen full-text articles (total articles screened: 2835) were included. Risk of bias for these articles was scored low. Seven trials provided sufficient data and were judged similar enough to be pooled for meta-analysis on binary outcomes. SCS intervention results in a higher prevalence of patients at work compared with before treatment (odds ratio [OR] 2.15; 95% confidence interval [CI], 1.44-3.21; I2 = 42%; p < 0.001). SCS treatment also results in high odds to return to work (OR 29.06; 95% CI, 9.73-86.75; I2 = 0%; p < 0.001). CONCLUSIONS: Based on available literature, SCS proved to be an effective approach to stimulate return to work in patients with specific chronic pain syndromes.

Development and Pilot Testing of 24/7 In-Ambulance Telemedicine for Acute Stroke: Prehospital Stroke Study at the Universitair Ziekenhuis Brussel-Project.

BACKGROUND: In-ambulance telemedicine is a recently developed and a promising approach to improve emergency care. We implemented the first ever 24/7 in-ambulance telemedicine service for acute stroke. We report on our experiences with the development and pilot testing of the Prehospital Stroke Study at the Universitair Ziekenhuis Brussel (PreSSUB) to facilitate a wider spread of the knowledge regarding this technique. METHODS: Successful execution of the project involved the development and validation of a novel stroke scale, design and creation of specific hardware and software solutions, execution of field tests for mobile internet connectivity, design of new care processes and information flows, recurrent training of all professional caregivers involved in acute stroke management, extensive testing on healthy volunteers, organisation of a 24/7 teleconsultation service by trained stroke experts and 24/7 technical support, and resolution of several legal issues. RESULTS: In all, it took 41 months of research and development to confirm the safety, technical feasibility, reliability, and user acceptance of the PreSSUB approach. Stroke-specific key information can be collected safely and reliably before and during ambulance transportation and can adequately be communicated with the inhospital team awaiting the patient. CONCLUSION: This paper portrays the key steps required and the lessons learned for successful implementation of a 24/7 expert telemedicine service supporting patients with acute stroke during ambulance transportation to the hospital.

Prehospital stroke care: limitations of current interventions and focus on new developments.

BACKGROUND: The global burden of stroke is immense, both in medical and economic terms. With the aging population and the ongoing industrialization of the third world, stroke prevalence is expected to increase and will have a major effect on national health expenditures. Currently, the medical treatment for acute ischemic stroke is limited to intravenous recombinant tissue plasminogen activator (IV r-tPA), but its time dependency leads to low utilization rates in routine clinical practice. Prehospital delay contributes significantly to delayed or missed treatment opportunities in acute stroke. State-of-the-art acute stroke care, starting in the prehospital phase, could thereby reduce the disease burden and its enormous financial costs. SUMMARY: The first part of this review focuses on current education measures for the general public, the emergency medical services (EMS) dispatchers and paramedics. Although much has been expected of these measures to improve stroke care, no major effects on prehospital delay or missed treatment opportunities have been demonstrated over the years. Most interventional studies showed little or no effect on the onset-to-door time, IV r-tPA utilization rates or outcome, except for prenotification of the receiving hospital by the EMS. No data are currently available on the cost-effectiveness of these commonly used measures. In the second part, we discuss new developments for the improvement of prehospital stroke diagnosis and treatment which could open new perspectives in the nearby future. These include the implementation of prehospital telestroke and the deployment of mobile stroke units. These approaches may improve patient care and could serve as a platform for prehospital clinical trials. Other opportunities include the implementation of noninvasive diagnostics (like transcranial ultrasound and blood-borne biomarkers) and the reevaluation of neuroprotective strategies in the prehospital phase. Key Messages: Timely initiation of treatment can effectively reduce the medical and economic burden of stroke and should begin with optimal prehospital stroke care. For this, prehospital telemedicine is a particularly attractive approach because it is a scalable solution that has the potential to rapidly optimize acute stroke care at limited cost.

Interventions to promote work participation after ischaemic stroke: A systematic review.

Only a disappointingly low proportion of patients successfully engage in professional activities after ischaemic stroke. This systematic review maps all contemporary evidence regarding interventions aiming to promote return-to-work in survivors of ischaemic stroke. We performed a search according to Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines and searched five reference databases. Prospective trial registers and grey literature were also assessed, and we executed backwards and forward reference searching. The study protocol was registered in PROSPERO (CRD42017077796). The search yielded 444 records of which 174 were duplicates. Backward and forward reference searching resulted in 808 unique records. Eleven articles were retained for full-text analysis and two met the selection criteria. A controlled before-after study showed beneficial effects of intravenous thrombolytic treatment in patients with moderate to severe acute ischaemic stroke. A retrospective study with low methodological quality reported improved vocational outcome of an outpatient rehabilitation program in patients with mild to moderate ischaemic stroke. We conclude that there currently is insufficient evidence regarding the effectiveness of interventions to promote return-to-work in patients with ischaemic stroke, though intravenous thrombolytic therapy has shown beneficial effects and there are indications that rehabilitation programs may also be advantageous.

Health Economic Evaluations of Digital Health Interventions for Secondary Prevention in Stroke Patients: A Systematic Review.

BACKGROUND: In the first 5 years after their stroke, about a quarter of patients will suffer from a recurrent stroke. Digital health interventions facilitating interactions between a caregiver and a patient from a distance are a promising approach to improve patient adherence to lifestyle changes proposed by secondary prevention guidelines. Many of these interventions are not implemented in daily practice, even though efficacy has been shown. One of the reasons can be the lack of clear economic incentives for implementation. We propose to map all health economic evidence regarding digital health interventions for secondary stroke prevention. SUMMARY: We performed a systematic search according to PRISMA-P guidelines and searched on PubMed, Web of Science, Cochrane, and National Institute for Health Research Economic Evaluation Database. Only digital health interventions for secondary prevention in stroke patients were included and all study designs and health economic outcomes were accepted. We combined the terms "Stroke OR Cardiovascular," "Secondary prevention," "Digital health interventions," and "Cost" in one search string using the AND operator. The search performed on April 20, 2017 yielded 163 records of which 26 duplicates were removed. After abstract screening, 20 articles were retained for full-text analysis, of which none reported any health economic evidence that could be included for analysis or discussion. Key Messages: There is a lack of evidence on health economic outcomes on digital health interventions for secondary stroke prevention. Future research in this area should take health economics into consideration when designing a trial and there is a clear need for health economic evidence and models.

Time Gain Needed for In-Ambulance Telemedicine: Cost-Utility Model.

BACKGROUND: Stroke is a very time-sensitive pathology, and many new solutions target the optimization of prehospital stroke care to improve the stroke management process. In-ambulance telemedicine, defined by live bidirectional audio-video between a patient and a neurologist in a moving ambulance and the automated transfer of vital parameters, is a promising new approach to speed up and improve the quality of acute stroke care. Currently, no evidence exists on the cost effectiveness of in-ambulance telemedicine. OBJECTIVE: We aim to develop a first cost effectiveness model for in-ambulance telemedicine and use this model to estimate the time savings needed before in-ambulance telemedicine becomes cost effective. METHODS: Current standard stroke care is compared with current standard stroke care supplemented with in-ambulance telemedicine using a cost-utility model measuring costs and quality-adjusted life-years (QALYs) from a health care perspective. We combine a decision tree with a Markov model. Data from the UZ Brussel Stroke Registry (2282 stroke patients) and linked hospital claims data at individual level are combined with literature data to populate the model. A 2-way sensitivity analysis varying both implementation costs and time gain is performed to map the different cost-effective combinations and identify the time gain needed for cost effectiveness and dominance. For several modeled time gains, the cost-effectiveness acceptability curve is calculated and mapped in 1 figure. RESULTS: Under the base-case scenario (implementation cost of US $159,425) and taking a lifetime horizon into account, in-ambulance telemedicine is a cost-effective strategy compared to standard stroke care alone starting from a time gain of 6 minutes. After 12 minutes, in-ambulance telemedicine becomes dominant, and this results in a mean decrease of costs by US -$30 (95% CI -$32 to -$29) per patient with 0.00456 (95% CI 0.00448 to 0.00463) QALYs on average gained per patient. In over 82% of all probabilistic simulations, in-ambulance telemedicine remains under the cost-effectiveness threshold of US $47,747. CONCLUSIONS: Our model suggests that in-ambulance telemedicine can be cost effective starting from a time gain of 6 minutes and becomes a dominant strategy after approximately 15 minutes. This indicates that in-ambulance telemedicine has the potential to become a cost-effective intervention assuming time gains in clinical implementations are realized in the future.

High-Density in Spinal Cord stimulation: Virtual Expert Registry (DISCOVER): Study Protocol for a Prospective Observational Trial.

BACKGROUND: Spinal cord stimulation (SCS) is a proven and effective treatment for neuropathic pain conditions such as failed back surgery syndrome (FBSS). The hypothesis that different settings for SCS parameters activate unique, pain-relieving mechanisms has boosted the development of various SCS paradigms. High density spinal cord stimulation (HD-SCS) is one of those promising, novel stimulation forms characterized by subthreshold stimulation, delivering more pulses per second and a higher pulse density to the spinal cord than conventional SCS. OBJECTIVES: The aim of DISCOVER is to gather evidence about the effectiveness, feasibility, and (possible) side effects of HD stimulation. METHODS: The prospective, non-interventional, multi-center, clinical study, DISCOVER, is currently restricted to Belgium where 19 neuromodulation centers were selected. Patient recruitment started in October 2016 and is expected to end in October 2017. Subjects included are (1) patients with insufficient pain relief from conventional SCS or (2) neurostimulation-naïve patients suited for SCS. Patients will be assessed 1 month, 3 months, and 12 months after conversion to HD-SCS settings. Each patient's visit will include: a numerical rating scale (NRS), Oswestry disability index (ODI), Pittsburgh sleep quality index (PSQI), EQ-5D, a pain map, registration of SCS settings, and a list of used pain medication. CONCLUSIONS: Although promising results have been reported, adequate registration of its effectiveness and (possible) side-effects remains an unmet need. Main results are expected in 2019.

Opinions and Beliefs About Telemedicine for Emergency Treatment During Ambulance Transportation and for Chronic Care at Home.

BACKGROUND: Telemedicine is a valid alternative to face-to-face patient care in many areas. However, the opinion of all stakeholders is decisive for successful adoption of this technique, especially as telemedicine expands into novel domains such as emergency teleconsultations during ambulance transportation and chronic care at home. OBJECTIVE: We evaluate the viewpoints of the broad public, patients, and professional caregivers in these situations. METHODS: A 10-question survey was developed and obtained via face-to-face interviews of visitors at the Universitair Ziekenhuis Brussel (UZB). The online questionnaire was also distributed among professional caregivers via the intranet of the UZB and among the broad public using social media. RESULTS: In total, 607 individuals responded to the questionnaire, expressing a positive opinion regarding telemedicine for in-ambulance emergency treatment and for chronic care at home. Privacy issues were not perceived as relevant, and most respondents were ready to participate in future teleconsultations. Lack of telecommunication knowledge (213/566, 37.6%) was the only independent factor associated with rejection of telemedicine at home and respondents via social media (250/607, 41.2%) were less concerned about privacy issues than respondents via face-to-face interviews (visitors, 234/607, 38.6%). The visitors were more positive towards in-ambulance telemedicine and more likely to agree with future participation in teleconsultations than respondents via social media. CONCLUSIONS: The broad public, professional caregivers, and patients reported a positive attitude towards telemedicine for emergency treatment during ambulance transportation and for chronic care at home. These results support further improvement of telemedicine solutions in these domains.

Feasibility of AmbulanCe-Based Telemedicine (FACT) study: safety, feasibility and reliability of third generation in-ambulance telemedicine.

BACKGROUND: Telemedicine is currently mainly applied as an in-hospital service, but this technology also holds potential to improve emergency care in the prehospital arena. We report on the safety, feasibility and reliability of in-ambulance teleconsultation using a telemedicine system of the third generation. METHODS: A routine ambulance was equipped with a system for real-time bidirectional audio-video communication, automated transmission of vital parameters, glycemia and electronic patient identification. All patients ( ≥ 18 years) transported during emergency missions by a Prehospital Intervention Team of the Universitair Ziekenhuis Brussel were eligible for inclusion. To guarantee mobility and to facilitate 24/7 availability, the teleconsultants used lightweight laptop computers to access a dedicated telemedicine platform, which also provided functionalities for neurological assessment, electronic reporting and prehospital notification of the in-hospital team. Key registrations included any safety issue, mobile connectivity, communication of patient information, audiovisual quality, user-friendliness and accuracy of the prehospital diagnosis. RESULTS: Prehospital teleconsultation was obtained in 41 out of 43 cases (95.3%). The success rates for communication of blood pressure, heart rate, blood oxygen saturation, glycemia, and electronic patient identification were 78.7%, 84.8%, 80.6%, 64.0%, and 84.2%. A preliminary prehospital diagnosis was formulated in 90.2%, with satisfactory agreement with final in-hospital diagnoses. Communication of a prehospital report to the in-hospital team was successful in 94.7% and prenotification of the in-hospital team via SMS in 90.2%. Failures resulted mainly from limited mobile connectivity and to a lesser extent from software, hardware or human error. The user acceptance was high. CONCLUSIONS: Ambulance-based telemedicine of the third generation is safe, feasible and reliable but further research and development, especially with regard to high speed broadband access, is needed before this approach can be implemented in daily practice.
