Process, content, and experiences of delivering the Carer Support Needs Assessment Tool Intervention (CSNAT-I) in the Danish specialised palliative care setting.

PURPOSE: The Carer Support Needs Assessment Tool Intervention (CSNAT-I) has shown positive effects in the Danish specialised palliative care (SPC) setting. Here, we explore the process, content, and experiences of delivering the CSNAT-I. METHODS: Data were collected during a stepped wedge cluster randomised controlled trial investigating the impact of the CSNAT-I in the Danish SPC setting in 2018-2019. Data were obtained from the CSNAT (tool) completed by caregivers, from health care professionals' (HCPs') written documentation of the CSNAT-I, and from semi-structured interviews with HCPs. RESULTS: The study population consisted of the 130 caregivers receiving a first CSNAT-I within 13 days of study enrolment, the 93 caregivers receiving a second CSNAT-I 15-27 days after enrolment, and the 44 HCPs delivering the intervention. Top three domains of unmet caregiver support needs reported in the CSNAT-I were: "knowing what to expect in the future," "dealing with feelings and worries," and "understanding the illness." These domains together with "knowing who to contact if concerned" and "talking to the patient about the illness" were also the domains most frequently prioritised for discussion with HCPs. According to HCPs, most often support delivered directly by HCPs themselves during the actual contact (e.g., listening, advice, information) was sufficient. Overall, HCPs experienced the CSNAT-I as constructive and meaningful, and difficulties in delivering the intervention were rarely an issue. CONCLUSION: The support needs reported by caregivers confirm the relevance of the CSNAT-I. HCPs' overall experiences of the clinical feasibility and relevance of the CSNAT-I were very positive.

Effect of the Carer Support Needs Assessment Tool intervention (CSNAT-I) in the Danish specialised palliative care setting: a stepped-wedge cluster randomised controlled trial.

BACKGROUND: The Carer Support Needs Assessment Tool intervention (CSNAT-I) has been shown to improve end-of-life care support for informal caregivers. This study investigated the impact of the CSNAT-I on caregivers of patients recently enrolled in specialised palliative care (SPC) at home in Denmark. METHODS: A stepped-wedge cluster randomised controlled trial with nine clusters (ie, SPC teams). Outcome measures were collected using caregiver questionnaires at baseline (T0) and 2-week (T1) and 4-week (T2) follow-up. RESULTS: A total of 437 caregivers were enrolled (control group, n=255; intervention group, n=182). No intervention effect was found on the primary outcome, caregiver strain at T1 (p=0.1865). However, positive effects were found at T1 and T2 on attention to caregivers' well-being (p<0.0001), quality of information and communication (p<0.0001), amount of information (T1: p=0.0002; T2: p<0.0001), involvement (T1: p=0.0045; T2: p<0.0001), talking about greatest burdens (p<0.0001) and assistance in managing greatest burdens (p<0.0001). The effect sizes of these differences were medium or large and seemed to increase from T1 to T2. At T1, positive effects were found on distress (p=0.0178) and home care responsibility (p=0.0024). No effect was found on the remaining outcomes. CONCLUSION: Although no effect was found on caregiver strain, the CSNAT-I showed positive effects on caregiver distress, home care responsibility and key outcomes regarding caregivers' experience of the interaction with healthcare professionals.

Differential effect of intravenous S-ketamine and fentanyl on atypical odontalgia and capsaicin-evoked pain.

Atypical odontalgia (AO) is an intraoral pain condition of currently unknown mechanisms. In 10 AO patients and 10 matched healthy controls, we examined the effect of intravenous infusion of an N-methyl-D-aspartate (NMDA) receptor antagonist S-ketamine and a mu-opioid agonist fentanyl on spontaneous AO pain and on an acute intraoral nociceptive input evoked by topical application of capsaicin. The drugs were administered in a randomized, placebo-controlled, cross-over manner. Furthermore, measures of intraoral sensitivity to mechanical and thermal quantitative sensory testing (QST) including temporal summation were compared between groups and sides. Both drugs failed to produce an analgesic effect on spontaneous AO pain, but fentanyl effectively reduced capsaicin-evoked pain. AO patients showed increased sensitivity to capsaicin and heat pain, but no significant differences in cold and mechanical sensitivity compared with healthy controls. No side-to-side differences in QST measures were found in AO patients. The present study demonstrates that AO is unlikely to be primarily due to a persistent afferent barrage from the peripheral region. Furthermore, in contrast to studies on various neuropathic pain conditions, fentanyl and S-ketamine in the present doses failed to attenuate AO pain.

Long-lasting mechanical sensitization following third molar surgery.

AIMS: To investigate the degree and duration of neuronal hyperexcitability due to local inflammatory trauma after surgical removal of an impacted mandibular third molar. METHODS: A total of 32 healthy men (16 patients, 16 control subjects) underwent quantitative sensory tests (QST) at baseline (preoperatively) and 2, 7, and 30 days following surgical removal of a mandibular third molar. Thermal and mechanical QST was applied to the extraoral and intraoral regions as well as to the dominant forearm. RESULTS: Detection thresholds for thermal and mechanical stimuli did not change over time in patients and control subjects, but pain thresholds (thermal, pressure, electrical) in the control group increased significantly. Patients showed significantly decreased pain pressure thresholds and pressure pain tolerance (P < .05 for both) on the operated side and absence of adaptation to the tests for up to 30 days postoperatively. CONCLUSION: These results indicate that even a minor surgical procedure in the orofacial region may be sufficient to evoke hyperexcitability in an area adjacent to the surgical wound for up to 30 days. The decreased adaptive capacity in the patient group also suggests the involvement of central pain-regulatory mechanisms in response to the surgical trauma.

Intravenous acetaminophen (paracetamol): comparable analgesic efficacy, but better local safety than its prodrug, propacetamol, for postoperative pain after third molar surgery.

We compared an acetaminophen (paracetamol) 1 g (n = 51) formulation for infusion with propacetamol 2 g (n = 51) and placebo (n = 50) in a randomized, controlled, double-blind, parallel group trial in patients with moderate-to-severe pain after third molar surgery. Treatment efficacy was assessed in house for 6 h after starting the 15-min infusion. Significant effects versus placebo (P < 0.01) were obtained with both active treatments on pain relief, pain intensity difference on a 100-mm visual analog scale, and on a categorical scale (except for propacetamol at 6 h). No significant differences were noted between active groups except at 1 h. Six-hour weighted sums of primary assessments showed significantly better efficacy than placebo (P < 0.0001) and no difference between active treatments. Median stopwatch time to onset of pain relief for active treatment was 6-8 min after infusion start. Active treatments showed comparable efficacy with a significantly longer duration of analgesia and better patients' global evaluation compared with placebo. The incidence of patients reporting local pain at the infusion site was significantly less frequent after IV acetaminophen or placebo (0%) in comparison with propacetamol (49%). In conclusion, acetaminophen 1 g and propacetamol 2 g were superior to placebo regarding analgesic efficacy, with a more frequent incidence of local pain at the infusion site for propacetamol.
