New analgesics are needed for painful wounds. Multiple reports suggest that topical sevoflurane may have analgesic effects. This placebo-controlled randomised trial evaluated the analgesic efficacy and safety of VPX638 (topical sevoflurane). Seventy-eight participants with painful wounds, were enrolled at eight Australian centres and randomly allocated to receive 2 × 5 mL of VPX638 (N = 39) or placebo (N = 40) during one wound dressing change. Numerical pain rating scores and use of opioids were recorded for 24 h. The primary endpoint was pain during wound cleaning, secondary endpoints evaluated pain for 24 h after drug application and opioids use. There was no significant difference in mean pain scores during wound cleaning between VPX638 and placebo (0.854; p = 0.23). The mean differences in summed pain intensity difference from baseline suggested VPX638 provided greater analgesia compared to placebo over 8 h (p < 0.02), 12 h (p < 0.01) and 24 h (p < 0.05) and significantly longer duration of analgesia, 24.3 h for VPX638 versus 7.1 h for placebo (p < 0.01). In the 24 h after drug administration, participants receiving VPX638 had a 50% decrease in opioid use over 24 h compared with placebo. VPX638 appeared safe and well-tolerated. In conclusion, this small placebo-controlled randomised trial suggested that VPX638 provides analgesia and is opioid-sparing for up to 24 h after wound cleaning. It supports the need for further evaluation of the benefit of VPX638 as a topical analgesic for painful wounds.

Introduction: Foot problems, including musculoskeletal problems, peripheral neuropathy, peripheral arterial disease and dermatologic pathology are common in older adults and are associated with an increased risk of falling. Multicomponent podiatry interventions have been shown to reduce the incidence of falls. This paper aimed to identify older adults requiring podiatry input in a Falls and Balance clinic; to describe the model of foot health care they receive; to explore cross-sectional associations between foot problems and function and ultimately demonstrate the role of podiatry input in the multidisciplinary management of falls risk. Methods: Cohort study of patients attending a Falls and Balance Clinic for Comprehensive Geriatric Assessment. Demographic information was collected and functional independence, mobility, foot problems, and footwear were assessed in the clinic. Results: One-hundred and two patients were included; median age 79.3 (73-84.3) years, 68.6% female, 93.1% residing independently, 62.7% used a gait aid. Podiatry referrals were made in 80.4% of cases, with muscle weakness being the most common problem identified (90.2%); 74.8% were found to be wearing inappropriate footwear. Most patients received footwear education and half were prescribed foot and ankle strengthening exercises. Hallux and lesser toe weakness were associated with lower Short Physical Performance Battery scores (p < 0.001). Conclusion: The majority of older adults in the Falls and Balance Clinic required podiatry input, with foot weakness and inappropriate footwear being common reasons for referral. Those with weakness of the hallux and lesser toes had poorer balance and mobility, which is known to be associated with greater falls risk. This highlights the need for podiatry assessment and interventions as part of the multidisciplinary approach to the management of falls risk in older adults. (c) 2024 S. Karger AG, Basel

BACKGROUND:Initial orthostatic hypotension (IOH) is highly prevalent in older adults and may interfere with the ability to regain function after acute hospitalization. IOH assessment requires a non-invasive, beat-to-beat continuous blood pressure device, which is not widely used in geriatric rehabilitation. Our aim was to test the feasibility of diagnosing IOH using a continuous blood pressure device in geriatric rehabilitation inpatients.METHODS:Geriatric rehabilitation inpatients of the REStORing Health of Acutely Unwell AdulTs (RESORT) cohort admitted to a tertiary hospital were randomly selected to undergo continuous blood pressure monitoring (Finapres) for 5 min in the supine position and 3 min of standing or sitting when unable to stand. Interventions to warm hands and adjusting the cuff pressure sizes were attempted if no signal was obtained or an error message occurred.RESULTS:Of 37 randomly selected inpatients, 29 {55.2% female; mean age 82.8 (standard deviation [SD]) 6.6 years} agreed to the continuous blood pressure measurement. Successful measurements were achieved in 20 out of 29 inpatients, two after hand warming. Patients with unsuccessful measurements were likely to be older (mean age 87.2 [SD] 4.4 years, p = 0.03), have cerebrovascular disease (p = 0.006), lower body mass index (p = 0.012), and a lower short physical performance battery score (p = 0.039). Eight out of 20 patients had IOH.CONCLUSION:The number of unsuccessful continuous blood pressure measurements was high in a population with high IOH prevalence despite multiple interventions to establish a signal. Future research should focus on improving the efficiency of continuous blood pressure devices in hospitalized patients with unsuccessful signals.

Background: Initial orthostatic hypotension (OH) is a clinical syndrome of exaggerated transient orthostasis associated with higher risks of falls, frailty and syncope in older adults. Objective: To provide a prevalence estimate of initial OH in adults aged 65 years or older. Methods: Literature search of MEDLINE (from 1946), Embase (from 1947) and Cochrane Central Register of Controlled Trials was performed until 6 December 2019, using the terms 'initial orthostatic hypotension', 'postural hypotension' and 'older adults'. Articles were included if published in English and participants were 65 years or older. Random effects models were used for pooled analysis. Results: Of 5,136 articles screened, 13 articles (10 cross-sectional; 3 longitudinal) reporting data of 5,465 individuals (54.5% female) from the general (n=4,157), geriatric outpatient (n=1,136), institutionalised (n=55) and mixed (n=117) population were included. Blood pressure was measured continuously and intermittently in 11 and 2 studies, respectively. Pooled prevalence of continuously measured initial OH was 29.0% (95% CI: 22.1-36.9%, I-2 = 94.6%); 27.8% in the general population (95% CI: 17.9-40.5%, I-2 = 96.1%), 35.2% in geriatric outpatients (95% CI: 24.2-48.1%, I-2 = 95.3%), 10.0% in institutionalised individuals (95% CI: 2.4-33.1%, I-2 = 0%) and 21.4% in the mixed population (95% CI: 7.0-49.6, I-2 = 0%). Pooled prevalence of intermittently measured initial OH was 5.6% (95% CI: 1.5-18.9%, I-2 = 81.1%); 1.0% in the general population (95% CI: 0.0-23.9%, I-2 = 0%) and 7.7% in geriatric outpatients (95% CI: 1.8-27.0%, I-2 = 86.7%). Conclusion: The prevalence of initial OH is high in older adults, especially in geriatric outpatients. Proper assessment of initial OH requires continuous blood pressure measurements.

OBJECTIVES:To systematically assess the literature examining the association between foot disease (foot ulceration, infection, critical ischaemia and/or Charcot neuroarthropathy) and physical function in older adults. METHODS:Literature search of MEDLINE, Embase and CINAHL was performed. Studies were included if foot disease and physical function were assessed in participants of mean or median age ≥ 65 years. RESULTS:Of 2,574 abstracts screened, 19 studies (13 longitudinal, 6 cross-sectional) reporting on 5634 participants, 43% female, were included. Diabetes-related foot disease and critical ischaemia were most studied (n = 5017, 40% female). In 8 studies with control groups, foot disease was associated with poorer physical function. Meta-analysis of 5 studies (n = 1503, 45% female) found an association between foot disease and poorer physical function (SMD (95% CI): 1.00 (0.40, 1.62), P < 0.001). CONCLUSION:Foot disease is associated with poorer physical function in older adults. Future research should include broader study populations and intervention strategies.

BACKGROUND:Orthostatic hypotension (OH) is common in older adults with reported prevalence rates of 5-40%. A direct link between OH and cognitive performance has been proposed due to impaired vascular autoregulation. AIM:To systematically assess the literature of the association between OH and cognitive performance in older adults. METHODS:Literature search of MEDLINE, Embase, Cochrane Central Register of Controlled Trials and PsycINFO from inception to May 2017. Studies were included if OH and cognition were assessed in subjects of mean or median age ≥65 years. Risk of bias was assessed with the Newcastle Ottawa Scale. RESULTS:Of 3266 studies screened, 32 studies (22 cross-sectional; 10 longitudinal) reporting data of 28,980 individuals were included. OH prevalence ranged from 3.3% to 58%. Of the 32 studies, 18 reported an association between OH and worse cognitive performance and 14 reported no association. Mini Mental State Examination (MMSE) was the most commonly used cognitive assessment tool. Studies using more than one cognitive assessment tool were more likely to find an association between OH and worse cognition. OH was significantly associated with a lower MMSE mean score (mean difference - 0.51 (95% CI: -0.85, -0.17, p = 0.003)) and an increased risk of cognitive impairment (OR 1.19 (95% CI, 1.00-1.42, p = 0.048)). CONCLUSIONS:OH is common in older populations and is associated with worse cognition expressed as lower MMSE scores. Use of MMSE alone as a cognitive assessment tool may underestimate the association. It is yet unclear whether the association between OH and worse cognitive performance is causative.

BACKGROUND:More than 49% of all US hospital days are spent caring for patients with delirium. There are few Australian data on this important condition. The aim of the study was to determine the prevalence and incidence of delirium in older medical inpatients in a metropolitan teaching hospital, the incidence of known risk factors and current practice in identifying and managing patients at risk of this condition. METHODS:Patients aged 65 years or more, and admitted to a general medical unit, were eligible for study inclusion. Participants were screened with an Abbreviated Mental Test Score (AMTS) and chart review. Confusion Assessment Method was used to diagnose delirium if confusion was documented or AMTS < 8. Barthel Index (BI), demographics, delirium risk factors and management were recorded. RESULTS:Prevalent delirium was diagnosed in 19 of 104 (18%) and incident delirium in 2 of 85 (2%) participants. Pre-existing cognitive impairment and admission AMTS < 8 were strongly associated with prevalent delirium (P-values < 0.01). Age > 80 years, Barthel Index < or = 50, use of high-risk medications and electrolyte disturbance were also associated with prevalent delirium. Prevalent delirium was not recognized by the treating unit in 4 of 19 cases (21%). Five of 104 (4.8%) of participants had a formal cognitive assessment on admission. One of 19 patients (5.3%) with prevalent delirium had an orientation device in their room. CONCLUSION:Pre-existing cognitive impairment and admission AMTS are strong predictors of delirium. Despite this, formal cognitive assessment is not routinely carried out in elderly medical patients. Recognition of delirium may be improved by routine cognitive assessment in elderly medical patients.
