The non-decussating and decussating trigeminothalamic tracts in humans: A combination of connectome-based tractography and histological validation.

BACKGROUND: Functional anatomical research proposed the existence of a bilateral trigeminal ascending system although the anatomy trajectories of the trigeminothalamic connections cranial to the pons remain largely elusive. This study therefore aimed to clarify the anatomical distributions of the trigeminothalamic connections in humans. METHODS: Advanced deterministic tractography to an averaged template of diffusion tensor imaging data from 1065 subjects from the Human Connectome Project was used. Seedings masks were placed in Montreal Neurological Institute standard space by use of the BigBrain histological dataset. Waypoint masks of the sensory thalamus was obtained from the Brainnetome Atlas. RESULTS: Tractography results were validated by use of the BigBrain histological dataset and Polarized Light Imaging microscopy. The trigeminothalamic tract bifurcated into a decussating ventral and a non-decussating dorsal tract. The ventral and dorsal tracts ascended to the contralateral thalamus and ipsilateral thalamus and reflected the ventral trigeminothalamic tract and the dorsal trigeminothalamic tract, respectively. The projection of the ventral trigeminothalamic tract and the dorsal trigeminothalamic tract to both thalami confirm the existence of a bilateral trigeminothalamic system in humans. CONCLUSIONS: Because our study is strictly anatomical, no further conclusions can be drawn with regard to physiological functionality. Future research should explore if the dorsal trigeminothalamic tract and the ventral trigeminothalamic tract actually transmit signals from noxious stimuli, this offers potential in understanding and possibly treating neuropathology in the orofacial region.

Role-Perceptions of Dutch Spiritual Caregivers in Implementing Multidisciplinary Spiritual Care: A National Survey.

BACKGROUND: During the course of their disease, patients are, apart from suffering physical discomfort, also confronted with psychological, social, and spiritual challenges. However, healthcare professionals often lack the knowledge and skills to address the spiritual dimension and are in need of support for taking this responsibility. Spiritual caregivers are experts in spiritual care, but their contribution to the integration of this care by other healthcare professionals is largely unknown. OBJECTIVE: The aim of this study was to investigate how Dutch spiritual caregivers view their role in increasing the integration of spiritual care in daily healthcare practice as provided by other healthcare professionals in the Netherlands, and how they address this role. METHODS: An online survey was conducted from May until June 2021 among spiritual caregivers working in Dutch healthcare. Data were analysed using descriptive statistics. RESULTS: The majority of the 174 respondents answered that they already fulfil a role in the integration of spiritual care by, for example, providing education, coaching on the job, or participating in multidisciplinary consultation. However, the majority of respondents experienced barriers to their contribution, such as confusion of terminology and use of language while collaborating with other healthcare professionals and reluctance to share information. CONCLUSIONS: While spiritual caregivers realise having the potential to make important contributions to the further process of integration of spiritual care into the daily practice of other healthcare professionals, some practices and perceptions, especially from within their own discipline, may hamper this.

Subcutaneous Stimulation as Add-on Therapy to Spinal Cord Stimulation in Patients With Persistent Spinal Pain Syndrome Significantly Increases the Total Electrical Charge per Second: Aspects on Stimulation Parameters and Energy Requirements of the Implanted Neurostimulators.

OBJECTIVE: In our previous multicenter randomized controlled trial, we demonstrated the clinical effectiveness of peripheral nerve field stimulation (PNFS) as add-on therapy to spinal cord stimulation (SCS) for the treatment of chronic back pain in patients with persistent spinal pain syndrome (PSPS) or failed back surgery syndrome (FBSS). To our knowledge, no previous study has investigated the effect of PNFS as an add-on to SCS on the energy consumption of the implanted neurostimulators. Therefore, in this study, we compared the specific stimulation parameters and energy requirements of a previously unreported group of patients with only SCS with those of a group of patients with SCS and add-on PNFS. We also investigated differences that might explain the need for PNFS in the treatment of chronic low back pain. MATERIALS AND METHODS: We analyzed 75 patients with complete sets of stimulation parameters, with 21 patients in the SCS-only group and 54 patients in the SCS + PNFS group. Outcome measures were average visual analog scale score, SCS parameters (voltage, frequency, and pulse width), SCS charge per second, and total charge per second. We analyzed baseline characteristics and differences between and within groups over time. RESULTS: Both groups had comparable patient characteristics at baseline and showed a significant decrease in back and leg pain. SCS charge per second did not significantly differ between the groups at baseline or at 12 months. The total charge per second was significantly higher in the active SCS + PNFS group than in the SCS-only group at baseline; in the SCS + PNFS group, this persisted for up to 12 months, and the SCS charge per second and total charge per second increased significantly over time. CONCLUSIONS: Our results show that add-on PNFS increases the total charge per second compared with SCS alone, as expected. However, further research is needed because our results do not directly explain why some patients require add-on PNFS to treat low back pain.

Identifying, exploring and integrating the spiritual dimension in proactive care planning: A mixed methods evaluation of a communication training intervention for multidisciplinary palliative care teams.

BACKGROUND: Patients receiving palliative care value attention given to their spiritual needs. However, these needs often remain unexplored as healthcare professionals lack the skills to identify and explore them and to integrate this information into care plans. AIM: To evaluate the effects of an interactive communication training intervention for palliative care teams in order to identify and explore the spiritual dimension and integrate it in patients' care plans. DESIGN: A mixed methods pre-post study, including self-assessment questionnaires, evaluation of videos with simulated consultations (applied competence) and medical record review (implementation). SETTING/PARTICIPANTS: Three palliative care teams including nurses (N = 21), physicians (N = 14) and spiritual caregivers (N = 3). RESULTS: The questionnaires showed an improvement on 'Patient and family-centred communication' of the End-of-life professional caregiver survey (+0.37, p < 0.01; the 8-item S-EOLC (+0.54, p < 0.01) and regarding the Spiritual Care Competence Scale, on the three subscales used (+0.27, p < 0.01, +0.29, p < 0.01 and +0.32, p < 0.01). Video evaluations showed increased attention being paid to patient's aims and needs. The medical record review showed an increase in anticipation on the non-somatic dimension (OR: 2.2, 95% CI: 1.2-4.3, p < 0.05) and, using the Mount Vernon Cancer Network assessment tool, addressing spiritual issues (OR: 10.9, 95% CI: 3.7-39.5, p < 0.001). CONCLUSIONS: Our training intervention resulted in increased palliative care professionals' competence in identifying and exploring patients' spiritual issues, and their integration in multidimensional proactive palliative care plans. The intervention directly addresses patients' spiritual concerns and adds value to their palliative care plans.

Spinal Cord Stimulation in Failed Back Surgery Syndrome: An Integrative Review of Quantitative and Qualitative Studies.

BACKGROUND: Spinal cord stimulation (SCS) is an established therapy of failed back surgery syndrome (FBSS), although the effects on daily functioning, quality of life (QoL), and patients' expectations, experiences, and satisfaction remain elusive. The current integrative review aimed to summarize the overall effects of SCS in patients with FBSS on pain relief, health-related QoL, and daily activities. MATERIALS AND METHODS: PubMed, CINAHL, Embase, ClinicalTrials.gov, gray literature, and reference lists of relevant articles were searched for additional papers. All included studies were assessed for risk of bias using the Mixed Methods Appraisal Tool. Following the methods of Whittemore and Knafl, an integrative review and a meta-analysis were performed. RESULTS: In total, 16 articles were included; 11 articles presented quantitative outcomes, and five articles presented qualitative data. Lower back pain, leg pain, overall pain, Oswestry Disability Index, EuroQol Five Dimensions Health Questionnaire three-level/five-level, and the physical component score of Short Form Health Survey (SF-36) significantly improved during all follow-up moments. Only the mental component score of the SF-36 did not significantly improve, compared with baseline. Heterogeneity was diversely present among the studies. Patients' expectations and goals were disparate, although patients seemed to desire a return to their pre-FBSS state. Experiences with regard to the outcomes showed that patients largely recuperated after SCS, although limitations were still present. Patients also expressed inconvenience with regard to the trial period, implantation location, and recharging of the implantable pulse generator. CONCLUSIONS: SCS showed beneficial effects on different domains of life in patients with FBSS. The quantitative analyses suggest an overall improvement in most domains, although patients' experiences show that limitations in daily life and living with the SCS system persist. Multiple extensive preoperative counseling sessions and discussions with patients are deemed necessary to improve patient satisfaction and meet their expectations. Shared decision-making and provision of complete information are key factors for success.

Haptotherapy for patients with cancer; experience of haptotherapists and reasons for consultation: A survey among haptotherapists.

BACKGROUND AND PURPOSE: Haptotherapy is a type of mind-body therapy that makes use of affective touch. This study aims to provide insights in reasons for haptotherapy for patients with cancer, and in experiences of haptotherapists with these patients. MATERIALS AND METHODS: In a cross-sectional study, a survey was conducted among 536 Dutch haptotherapists. Multiple-choice and open-ended questions were analyzed both quantitatively and qualitatively. RESULTS: Of 272 (50.7%) responding haptotherapists, 167 (61.5%) had experience with treating people with cancer. Most frequently, combinations of emotional problems and a disturbed body experience were reported as reasons for haptotherapy. Haptotherapists emphasized the need for affective touch to restore patients' body connection. CONCLUSION: Two-thirds of the respondents treat patients with cancer, addressing the interaction of body and mind. Reasons for consultation cover a wide range of problems in multiple dimensions, in which a disturbed body experience in combination with emotional problems is mentioned most often.

Experiences From the Patient Perspective on Spinal Cord Stimulation for Failed Back Surgery Syndrome: A Qualitatively Driven Mixed Method Analysis.

INTRODUCTION: When neither pharmacological therapies nor alternative interventions provide sufficient pain relief, spinal cord stimulation (SCS) can be used to treat Failed Back Surgery Syndrome (FBSS). Although it seems reasonable that quality of life (QoL)- and psychosocial-related factors contribute to the outcome of SCS since pain is a multidimensional experience, few qualitative studies have explored the expectations of SCS and experiences on SCS to treat FBSS from the patient perspective. OBJECTIVES: The aim of this study was to qualitatively and quantitatively map the FBSS patients' experiences with SCS and the effects of SCS on low back pain caused by FBSS. MATERIALS AND METHODS: A qualitative study with in-depth semi-structured interviews, assisted by the Brief Pain Inventory (BPI)-questionnaire. RESULTS: Seven themes regarding patients' experiences, subdivided into 15 categories, were identified, including an understudied theme within this field of research, Spiritual Well-Being. "Acceptance" and "coping" emerged as pre-eminent motifs throughout these themes. Moreover, the realization of patients' expectations were variable throughout the presented themes. According to the BPI Questionnaire, four out of 13 patients (31%) had significant pain relief (≥50%). Seven out of 13 (54%) reported a ≥50% increase regarding enjoyment of life. CONCLUSION: Multiple QoL- and psychosocial-related themes are related to SCS-outcomes. In order to improve SCS-outcomes for both short- and long-term, these themes should be implemented as a multidimensional approach, both prior to implantation as during follow-up.

Peripheral Nerve Field Stimulation for Chronic Back Pain: Therapy Outcome Predictive Factors.

OBJECTIVE: To identify variables that influence pain reduction following peripheral nerve field stimulation (PNFS) in order to identify a potential responder profile. METHODS: Exploratory univariate and multivariate (random forest) analyses were performed separately on 2 randomized controlled trials and a registry; all included patients with chronic back pain, mainly failed back surgery syndrome. An international expert panel judged the clinical relevance of variables to identify responders by consensus. RESULTS: Variables identified that may help predict PNFS success in patients with back pain include patient and pain characteristics (age, time since onset of pain and spinal surgery, pain medication history, position and size of pain area, pain severity, mixed nociceptive/neuropathic pain, health-related quality of life, depression, functional disability, and leg pain status), implant procedure variables (the number and position of leads, paresthesia coverage, and amount of pain relief during the trial), and programming (number of programs, cathodes, and anodes; pulse rate; pulse width; and percentage of device usage). CONCLUSIONS: While these analyses are exploratory and restricted to a limited sample size, they suggest variables that may play a role in predicting a therapeutic response. These results, however, are informative only and should be cautiously interpreted. Future research to validate the variables in a clinical study is needed.

Invasive Motor Cortex Stimulation Influences Intracerebral Structures in Patients With Neuropathic Pain: An Activation Likelihood Estimation Meta-Analysis of Imaging Data.

OBJECTIVE: Invasive motor cortex stimulation (iMCS) has been proposed as a treatment for intractable neuropathic pain syndromes. Although the mechanisms underlying the analgesic effect of iMCS remain largely elusive, several studies found iMCS-related changes in regional cerebral blood flow (rCBF) in neuropathic pain patients. The aim of this study was to meta-analyze the findings of neuroimaging studies on rCBF changes to iMCS. METHODS: PubMed, Embase, MEDLINE, Google Scholar, and the Cochrane Library were systematically searched for retrieval of relevant scientific papers. After initial assessment of relevancy by screening title and abstract by two investigators, independently, predefined inclusion and exclusion criteria were used for final inclusion of papers. Descriptive results were statistically assessed, whereas coordinates were pooled and meta-analyzed in accordance with the activation likelihood estimation (ALE) methodology. RESULTS: Six studies were included in the systematic narrative analysis, suggesting rCBF increases in the cingulate gyrus, thalamus, insula, and putamen after switching the MCS device "ON" as compared to the "OFF" situation. Decreases in rCBF were found in for example the precentral gyrus and different occipital regions. Two studies did not report stereotactic coordinates and were excluded from further analysis. ALE meta-analysis showed that, after switching the iMCS electrode "ON," increased rCBF occurred in the (1) anterior cingulate gyrus; (2) putamen; (3) cerebral peduncle; (4) precentral gyrus; (5) superior frontal gyrus; (6) red nucleus; (7) internal part of the globus pallidus; (8) ventral lateral nucleus of the thalamus; (9) medial frontal gyrus; (10) inferior frontal gyrus; and (11) claustrum, as compared to the "OFF" situation. Reductions in rCBF were found in the posterior cingulate gyrus when the iMCS electrode was turned "OFF." CONCLUSIONS: These findings suggested that iMCS induces changes in principal components of the default mode-, the salience-, and sensorimotor network.

Systematic Review and Neural Network Analysis to Define Predictive Variables in Implantable Motor Cortex Stimulation to Treat Chronic Intractable Pain.

Implantable motor cortex stimulation (iMCS) has been performed for >25 years to treat various intractable pain syndromes. Its effectiveness is highly variable and, although various studies revealed predictive variables, none of these were found repeatedly. This study uses neural network analysis (NNA) to identify predictive factors of iMCS treatment for intractable pain. A systematic review provided a database of patient data on an individual level of patients who underwent iMCS to treat refractory pain between 1991 and 2017. Responders were defined as patients with a pain relief of >40% as measured by a numerical rating scale (NRS) score. NNA was carried out to predict the outcome of iMCS and to identify predictive factors that impacted the outcome of iMCS. The outcome prediction value of the NNA was expressed as the mean accuracy, sensitivity, and specificity. The NNA furthermore provided the mean weight of predictive variables, which shows the impact of the predictive variable on the prediction. The mean weight was converted into the mean relative influence (M), a value that varies between 0 and 100%. A total of 358 patients were included (202 males [56.4%]; mean age, 54.2 ±13.3 years), 201 of whom were responders to iMCS. NNA had a mean accuracy of 66.3% and a sensitivity and specificity of 69.8% and 69.4%, respectively. NNA further identified 6 predictive variables that had a relatively high M: 1) the sex of the patient (M = 19.7%); 2) the origin of the lesion (M = 15.1%); 3) the preoperative numerical rating scale score (M = 9.2%); 4) preoperative use of repetitive transcranial magnetic stimulation (M = 7.3%); 5) preoperative intake of opioids (M = 7.1%); and 6) the follow-up period (M = 13.1%). The results from the present study show that these 6 predictive variables influence the outcome of iMCS and that, based on these variables, a fair prediction model can be built to predict outcome after iMCS surgery. PERSPECTIVE: The presented NNA analyzed the functioning of computational models and modeled nonlinear statistical data. Based on this NNA, 6 predictive variables were identified that are suggested to be of importance in the improvement of future iMCS to treat chronic pain.

Long-Term Effect of Peripheral Nerve Field Stimulation as Add-On Therapy to Spinal Cord Stimulation to Treat Low Back Pain in Failed Back Surgery Syndrome Patients: A 12-Month Follow-Up of a Randomized Controlled Study.

OBJECTIVE: Different approaches in neuromodulation have been used to treat chronic low back pain in failed back surgery syndrome (FBSS) patients. We previously randomized 52 FBSS patients to be treated with spinal cord stimulation (SCS) and additional peripheral nerve field stimulation (PNFS) or SCS alone. At three months, we found a significant reduction of back pain in the PNFS-SCS group compared to the SCS group. In the subsequent open phase part of the study, all patients received optimal SCS and PNFS simultaneously. Here, we present the 12-month follow-up data on back and leg pain. MATERIALS AND METHODS: Data regarding back and leg pain, function, quality of life, patient satisfaction, anxiety and depression, and use of medication were collected by analyzing patients' questionnaires at 12 months and compared with data collected at baseline. Data were analyzed using multilevel regression models. RESULTS: A combined group of 50 subjects completed the 12-month follow-up. Back pain, measured on a 100-mm visual analog scale (VAS), significantly decreased over this period by 30.0 mm (95% CI: [-37.7/-22.4]; p < 0.001), while leg pain decreased by 43.7 mm (95% CI: [-51.5/-36.2]; p < 0.001). We observed statistically significant improvement in almost all secondary outcome measurements. CONCLUSIONS: At 12-month follow-up, PNFS in addition to SCS continues to provide a statistically significant and clinically relevant relief of low back pain in FBSS patients in whom SCS alone is effective for relief of leg pain only.

Nurses Exploring the Spirituality of Their Patients With Cancer: Participant Observation on a Medical Oncology Ward.

BACKGROUND: Attention for spirituality should be an integral part of professionals' caregiving. Particularly, nurses caring for patients with cancer might have opportunities to give attention to this dimension. OBJECTIVE: The aim of this study was to gain insight in the way and extent to which nurses during daily caregiving observe and explore spiritual issues of hospitalized patients with cancer. METHODS: We performed an ethnographic study with participant observation. Data were collected in 2015 during 4 shifts at the medical oncology department of a university hospital. The researcher, a spiritual care provider (chaplain) wearing the same kind of uniform as the nurses, observed the nurses, participated in their actions, and interviewed them after the shift. RESULTS: Although the patients did send many implicit and explicit messages concerning spiritual issues, the nurses did not explore them. If noticed, 3 barriers for exploring spiritual issues were mentioned by the nurses: lack of time, conflict with their mindset, and being reserved to talk about such issues. CONCLUSIONS: During their daily caregiving to patients with a life-threatening illness, nurses have many opportunities to explore spiritual issues, but they do not often recognize them. If they do, they tend not to explore the spiritual issues. IMPLICATIONS FOR PRACTICE: Communication training for nurses is necessary to develop skills for exploring the spiritual dimension in patients with cancer. In such training, attention to the misconception that such a conversation requires a lot of time and for recognizing signals from patients inviting an exploration of their concerns is necessary.

Multidisciplinary Training on Spiritual Care for Patients in Palliative Care Trajectories Improves the Attitudes and Competencies of Hospital Medical Staff: Results of a Quasi-Experimental Study.

OBJECTIVES: Patients value health-care professionals' attention to their spiritual needs. However, this is undervalued in health-care professionals' education. Additional training is essential for implementation of a national multidisciplinary guideline on spiritual care (SC) in palliative care (PC). Aim of this study is to measure effects of a training program on SC in PC based on the guideline. METHODS: A pragmatic multicenter trial using a quasi-experimental pretest-posttest design as part of an action research study. Eight multidisciplinary teams in regular wards and 1 team of PC consultants, in 8 Dutch teaching hospitals, received questionnaires before training about perceived barriers for SC, spiritual attitudes and involvement, and SC competencies. The effect on the barriers on SC and SC competencies were measured both 1 and 6 months after the training. RESULTS: For nurses (n = 214), 7 of 8 barriers to SC were decreased after 1 month, but only 2 were still after 6 months. For physicians (n = 41), the training had no effect on the barriers to SC. Nurses improved in 4 of 6 competencies after both 1 and 6 months. Physicians improved in 3 of 6 competencies after 1 month but in only 1 competency after 6 months. SIGNIFICANCE OF RESULTS: Concise SC training programs for clinical teams can effect quality of care, by improving hospital staff competencies and decreasing the barriers they perceive. Differences in the effects of the SC training on nurses and physicians show the need for further research on physicians' educational needs on SC.

How continuity of care is experienced within the context of integrated palliative care: A qualitative study with patients and family caregivers in five European countries.

BACKGROUND: Patients with advanced diseases often experience deficient continuity of care. Although integrated palliative care promotes continuity of care, it is not clear how it can be optimized to improve continuity of care experiences. AIM: To examine how relational, informational and management continuity of care are experienced by patients with advanced diseases and their family caregivers receiving care from several integrated palliative care initiatives in five European countries. DESIGN: We adopted a longitudinal qualitative study design including two interviews (interval 3 months) with patients and family caregivers focusing on how health care professionals responded to their needs. Interviews were audio-recorded and transcribed verbatim. Analysis involved a two-step qualitative content approach. SETTING/PARTICIPANTS: A total of 22 integrated palliative care initiatives (established local palliative care collaborations) were selected in Belgium, Germany, Hungary, the Netherlands and the United Kingdom. We recruited 152 patients (63% cancer, 24% chronic obstructive pulmonary disease, 13% heart failure; life expectancy <1 year; mean age 68 years, 56% female) and 92 family caregivers (mean age 61 years, 66% female). RESULTS: Trusted relationships with a small number of key health care professionals to receive tailored care and easily access help were essential. Relational continuity was often deficient, especially with general practitioners. Although informational and management continuity was often lacking in care provision, collaborative integrated palliative care initiatives were related to consistent and coherent care. CONCLUSION: Patients and family caregivers most likely experience continuity of care by having a small number of trusted health care professionals who are available, provide multidisciplinary care and regularly transfer information to all health care professionals involved. Optimizing continuity of care requires further integration of integrated palliative care initiatives with other health care professionals involved in the patients' care networks.

Pharmacological Treatment of Pain in Cancer Patients: The Role of Adjuvant Analgesics, a Systematic Review.

CONTEXT: In patients with cancer, pain is one of the most feared and burdensome symptoms. Adjuvant analgesics are an important cornerstone on which treatment of pain in patients with cancer is based. OBJECTIVES: To update our guidelines for the treatment of pain in patients with cancer, we performed a systematic review on the use of adjuvant analgesics in pain in cancer. METHODS: A systematic search of the literature was performed searching for articles that studied the effect of (1) antidepressants, (2) anti-epileptics, (3) N-methyl-d-aspartate (NMDA) receptor antagonists, and (4) other adjuvant analgesics in patients with cancer pain and described their effects on pain intensity and/or side effects. RESULTS: Based on the keywords and after reading the full papers, we could include 12 papers on anticonvulsants, 10 papers on antidepressants, four on NMDA receptor antagonists, and 10 papers on other adjuvant analgesics. The methodological quality of the included papers was graded as low to very low. Overall, there was a low quality of evidence that gabapentin, pregabalin, amitriptyline, and venlafaxine were effective in reducing pain intensity in patients with cancer pain. There was insufficient evidence on the effectiveness of lamotrigine, levetiracetam, NMDA antagonists, cannabinoids, corticosteroids, and local anesthetics on reducing pain intensity in patients with cancer pain. CONCLUSION: The quality of currently available evidence on the effectiveness of adjuvant analgesics in the treatment of cancer pain is low. The treatment of pain associated with cancer should be tailored to the patient's personal preferences.

'Life is still worth living': a pilot exploration of self-reported resources of palliative care patients.

BACKGROUND: Facing a terminal illness can be highly stressful and palliative care patients frequently suffer from mood symptoms. The focus of health care is often on treating symptoms whereas health-promoting factors receive less attention. The aim of this study was to explore the views of palliative care patients on resources and ways of coping that help them prevent or manage mood symptoms. METHODS: A pilot qualitative study was performed through face-to-face semi-structured interviews with fifteen ambulant patients with advanced cancer. The interviews were transcribed verbatim and qualitative analysis was performed independently by two researchers, according to the principle of constant comparative analysis. RESULTS: Patients reported on attitudes and specific coping strategies that they found helpful, as well as aspects of their life narrative and spirituality. Resources were found in meaningful contacts with family and friends and in personal attention of professional medical caregivers for their wellbeing. CONCLUSIONS: We conclude that palliative care patients could identify resources to cope with mood symptoms in the context of their unique life. In helping patients to identify the personal resources that are accessible and available in their specific context, patient autonomy in enhancing resilience could be increased.

Subcutaneous Stimulation as ADD-ON Therapy to Spinal Cord Stimulation Is Effective in Treating Low Back Pain in Patients With Failed Back Surgery Syndrome: A Multicenter Randomized Controlled Trial.

OBJECTIVE: Suppression of back pain with traditional spinal cord stimulation (SCS) in failed back surgery syndrome patients is often insufficient. The objective of this study was to investigate the efficacy of subcutaneous stimulation (SubQ) as ADD-ON therapy to SCS in treating back pain in failed back surgery syndrome patients. MATERIALS AND METHODS: Patients with a minimal pain score of 50 on a 100 mm visual analog scale for both leg and back pain were eligible. If pain reduction after trial SCS was ≥50% for the leg but <50% for the back, patients received additional SubQ leads and were randomized in a 1:1 ratio in a study arm with subcutaneous leads switched on (SubQ ADD-ON) and an arm with subcutaneous leads switched off (Control). The primary outcome was the percentage of the patients, at three months since implantation, with ≥50% reduction of back pain. RESULTS: A total of 97 patients were treated with SCS for leg and back pain. Of these, 52 patients were randomized and allocated to the Control group (n = 24) or to the SubQ ADD-ON group (n = 28). The percentage of patients with ≥50% reduction of back pain was significantly higher in the SubQ ADD-ON group (42.9%) compared to the Control group (4.2%). Mean visual analog scale for back pain, at three months, was a statistically significant 28.1 mm lower in the SubQ ADD-ON group compared to the Control group. CONCLUSION: Subcutaneous stimulation as an ADD-ON therapy to SCS is effective in treating back pain in failed back surgery syndrome patients where SCS is only effective for pain in the leg.

Teleconsultation for integrated palliative care at home: A qualitative study.

BACKGROUND: Interprofessional consultation contributes to symptom control for home-based palliative care patients and improves advance care planning. Distance and travel time, however, complicate the integration of primary care and specialist palliative care. Expert online audiovisual teleconsultations could be a method for integrating palliative care services. AIM: This study aims to describe (1) whether and how teleconsultation supports the integration of primary care, specialist palliative care, and patient perspectives and services and (2) how patients and (in)formal caregivers experience collaboration in a teleconsultation approach. DESIGN: This work consists of a qualitative study that utilizes long-term direct observations and in-depth interviews. SETTING/PARTICIPANTS: A total of 18 home-based palliative care patients (16 with cancer, 2 with chronic obstructive pulmonary disease; age range 24-85 years old), 12 hospital-based specialist palliative care team clinicians, and 17 primary care physicians. RESULTS: Analysis showed that the introduction of specialist palliative care team-patient teleconsultation led to collaboration between primary care physicians and specialist palliative care team clinicians in all 18 cases. In 17/18 cases, interprofessional contact was restricted to backstage work after teleconsultation. In one deviant case, both the patient and the professionals were simultaneously connected through teleconsultation. Two themes characterized integrated palliative care at home as a consequence of teleconsultation: (1) professionals defining responsibility and (2) building interprofessional rapport. CONCLUSION: Specialist palliative care team teleconsultation with home-based patients leads to collaboration between primary care physicians and hospital-based palliative care specialists. Due to cultural reasons, most collaboration was of a multidisciplinary character, strongly relying on organized backstage work. Interdisciplinary teleconsultations with real-time contact between patient and both professionals were less common but stimulated patient-centered care dialogues.
