Prehospital Pain and Analgesic Therapy in Elderly Patients with Hip Fractures

Prehospital analgesia in suspected hip fracture patients: adherence to national prehospital pain management guidelines

PURPOSE

Patients with hip fractures frequently present at the emergency department (ED). Despite high pain scores, prehospital pain management is often inadequate and insufficient. In the Netherlands, the emergency medical services (EMS) exhibit a high level of training, supported by a comprehensive pain treatment protocol. This study aimed to assess adherence to the protocol and hypothesized that prehospital pain management in hip fracture patients was both sufficient and adequate.

METHODS

This was a retrospective observational cohort study of patients with suspected hip fractures. The median differences in numerical rating scale (NRS) pain scores between the initial score in the ambulance and upon arrival at the ED were compared. Furthermore, adherence to the ambulance pain protocol was studied.

RESULTS

From September 2016 to March 2021, 436 ambulance-transported hip fracture patients were included, of whom 81% received analgesics by EMS. The median initial pain score measured by EMS was 8; this number decreased to 5 at ED presentation, a significant decrease (ρ < 0.001). In case a prehospital NRS pain score was assessed, 66.5% of the patients were treated according to the protocol. In 80% of patients, the protocol was not followed correctly, primarily due to missing NRS pain scores.

CONCLUSION

In suspected hip fracture patients, initial prehospital pain scores were high and most patients received analgesics from EMS. This resulted in a significant decrease in pain. In nearly 67% of patients in whom an NRS pain score was assessed in the prehospital phase, pain management was according to protocol. However, in 80% of the total population the pain protocol was not adhered to, mainly due to missing NRS pain scores.

Research priorities for prehospital care of older patients with injuries: scoping review

BACKGROUND AND OBJECTIVE

There is increasing recognition of the importance of prehospital trauma care for older patients, but little systematic research to guide practice. We aimed to review the published evidence on prehospital trauma care for older patients, determine the scope of existing research and identify research gaps in the literature.

METHODS

We undertook a systematic scoping review guided by the Arksey and O'Malley framework and reported in line with the PRISMA-ScR checklist. A systematic search was conducted of Scopus, CINAHL, MEDLINE, PubMed and Cochrane library databases to identify articles published between 2001 and 2021. Study selection criteria were applied independently by two reviewers. Data were extracted, charted and summarised from eligible articles. A data-charting form was then developed to facilitate thematic analysis. Narrative synthesis then involved identifying major themes and subthemes from the data.

RESULTS

We identified and reviewed 65 studies, and included 25. We identified five categories: 'field triage', 'ageing impacts', 'decision-making', 'paramedic' awareness' and 'paramedic's behaviour'. Undertriage and overtriage (sensitivity and specificity) were commonly cited as poorly investigated field-triage subthemes. Ageing-related physiologic changes, comorbidities and polypharmacy were the most widely researched. Inaccurate decision-making and poor early identification of major injuries were identified as potentially influencing patient outcomes.

CONCLUSION

This is the first study reviewing the published evidence on prehospital trauma care for older patients and identifying research priorities for future research. Field-triage tools, paramedics' knowledge about injuries in the older population, and understanding of paramedics' negative behaviours towards older patients were identified as key research priorities.

Use of Intravenous Paracetamol Preoperatively Favors Lower Risk of Delirium and Functional Recovery in Elderly Patients with Hip Fracture: A Propensity Score-Matched Analysis

We aimed to investigate whether the use of intravenous paracetamol (IVP) preoperatively in intertrochanteric fracture (IF) patients aged 65 years or over receiving intramedullary fixation had significantly benefits on the pain score at discharge, delirium incidence, length of hospital stay (LOS), functional outcomes, and mortality. A retrospective analysis of all surgically treated patients presenting with IF was conducted at a single Level I trauma center in China between Jan. 2016 and Jan. 2020. The data concerning patients' demographics, injury-related data, surgery-related data, operation-related data, in-hospital data, and postoperative outcomes were extracted. To minimize potential confounding and selection bias, the propensity score matching (PSM) method was performed via the caliper matching method by using a 1 : 1 ratio. After PSM, McNemar's chi-square tests were used to examine the association of using IVP with outcome analyses. The Spearman correlations of IVP using, pain scores, and the factors which may influence them were also computed. After screening 2963 consecutive patients, 2166 were included finally, including 1576 in the non-IVP group and 590 in the IVP group. After PSM, 531 remained in each group. The pain scores at discharge were significantly between the two groups before and after matching (all p < 0.001). The differences of delirium rate and functional outcomes became significant after propensity score-based matching (p=0.001 and 0.033, respectively), although they were not significant before matching. No significant difference was observed in other operation-related data, LOS, and crude mortality rates at 30-day, 90-day, and 12-month before and after PSM. In conclusion, this study highlights the need for preoperative IVP use to optimize pain control, postoperative functional recovery, and minimize pain-related comorbidities such as delirium in elderly patients with hip fracture.

Review article: Paramedic pain management of femur fractures in the prehospital setting: A systematic review

Femur shaft and neck of femur (NOF) fractures are often undertreated in the prehospital setting. These injuries can present unique clinical and logistical concerns in the prehospital setting. This systematic review aimed to investigate paramedic prehospital pain management of patients who had suffered NOF or femur fractures, and to investigate which interventions are effective. A systematic review was conducted in line with Preferred Reporting Item for Systematic Reviews and Meta-Analyses guidelines. Four databases were searched from inception date 23 March 2020. Articles were independently reviewed by two authors and conflicts resolved by a third author, followed by a hand search of the included reference lists. References were included if they addressed paramedic interventions for NOF or femur shaft fractures. Outcomes of interest were the effectiveness and complications of different modalities administered by paramedics. The search yielded 6868 articles, of which 19 met the final inclusion criteria. Studies investigated a variety of interventions including traction splints, intravenous (IV) analgesia and alternative analgesic options. Traction splinting and IV analgesia were consistently reported as underutilised. Alternative analgesics such as auricular acupressure, transcutaneous electrical nerve stimulation (TENS) and fascia iliaca compartment block were found to be effective techniques that could be safely and competently employed by paramedics, reducing pain for patients with limited adverse events. NOF and femur shaft fractures are an undertreated injury in the prehospital setting. Traction splinting and IV analgesia remain the traditional methodologies of treatment for these injuries; however, there are alternatives such as TENS, auricular acupressure and fascia iliaca compartment block that appear to be emerging as safe and effective options for the prehospital setting.

Orthogeriatric Management: Improvements in Outcomes during Hospital Admission Due to Hip Fracture

Hip fractures are an important socio-economic problem in western countries. Over the past 60 years orthogeriatric care has improved the management of older patients admitted to hospital after suffering hip fractures. Quality of care in orthogeriatric co-management units has increased, reducing adverse events during acute admission, length of stay, both in-hospital and mid-term mortality, as well as healthcare and social costs. Nevertheless, a large number of areas of controversy regarding the clinical management of older adults admitted due to hip fracture remain to be clarified. This narrative review, centered in the last 5 years, combined the search terms "hip fracture", "geriatric assessment", "second hip fracture", "surgery", "perioperative management" and "orthogeriatric care", in order to summarise the state of the art of some questions such as the optimum analgesic protocol, the best approach for treating anemia, the surgical options recommendable for each type of fracture and the efficiency of orthogeriatric co-management and functional recovery.

Assessment and Early Management of Pain in Hip Fractures: The Impact of Paracetamol

Introduction

As the number of patients sustaining hip fractures increases, interventions aimed at improving patient comfort and reducing complication burden acquire increased importance. Frailty, cognitive impairment, and difficulty in assessing pain control characterize this population. In order to inform future care, a review of pain assessment and the use of preoperative intravenous paracetamol (IVP) is presented.

Materials and Methods

Systematic review of preoperative IVP administration in patients presenting with a hip fracture.

Results

Intravenous paracetamol is effective in the early management of pain control in the hip fracture population. There is a considerable decrease in use of breakthrough pain medications when compared with other pain relief modalities. Additionally, IVP reduces the incidence of opioid-induced complications, reduces length of stay, and lowers mean pain scores. Another significant finding of this study is the poor administration of all analgesics to patients with hip fracture with up to 72% receiving no prehospital analgesia.

Discussion

The potential benefits of IVP as routine in the early management of hip fracture-related pain are clear. Studies of direct comparison between analgesia regimes to inform optimum bundles of analgesic care are sparse. This study highlights the need for properly constructed pathway-driven comparator studies of contemporary analgesia regimes, with IVP as a central feature to optimize pain control and minimize analgesia-related morbidity in this vulnerable population.

Patient and clinician factors associated with prehospital pain treatment and outcomes: cross sectional study

OBJECTIVE

We aimed to identify how patient (age, sex, condition) and paramedic factors (sex, role) affected prehospital analgesic administration and pain alleviation.

METHODS

We used a cross-sectional design with a 7-day retrospective sample of adults aged 18 years or over requiring primary emergency transport to hospital, excluding patients with Glasgow Coma Scale below 13, in two UK ambulance services. Multivariate multilevel regression using Stata 14 analysed factors independently associated with analgesic administration and a clinically meaningful reduction in pain (≥2 points on 0-10 numerical verbal pain score [NVPS]).

RESULTS

We included data on 9574 patients. At least two pain scores were recorded in 4773 (49.9%) patients. For all models fitted there was no significant relationship between analgesic administration or pain reduction and sex of the patient or ambulance staff. Reduction in pain (NVPS ≥2) was associated with ambulance crews including at least one paramedic (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.14 to 2.04, p < 0.01), with any recorded pain score and suspected cardiac pain (OR 2.2, 95% CI 1.02 to 4.75). Intravenous morphine administration was also more likely where crews included a paramedic (OR 2.82, 95% CI 1.93 to 4.13, P < 0.01), attending patients aged 51 to 64 years (OR 2.04, 95% CI 1.21 to 3.45, p = 0.01), in moderate to severe (NVPS 4-10) compared with lower levels of pain for any clinical condition group compared with the reference condition.

CONCLUSION

There was no association between patient sex or ambulance staff sex or grade and analgesic administration or pain reduction.

Analgesia by telemedically supported paramedics compared with physician-administered analgesia: A prospective, interventional, multicentre trial

BACKGROUND

In German emergency medical services (EMS), the analgesia is restricted to physicians. In this prospective, interventional, multicentre trial, complications with and quality of telemedically delegated analgesia were evaluated.

METHODS

If prehospital analgesia was necessary, five telemedically equipped paramedic ambulances from four different districts could consult a telemedicine centre. Analgesics were delegated based on a predefined algorithm. Telemedically assisted cases were compared with local historical regular EMS missions using matched pairs. The primary outcome was the frequency of therapeutic complications (respiratory/circulatory insufficiency, allergic reactions). Secondary outcomes were quality of analgesia (11-point numerical rating scale, NRS) and the frequency of nausea/vomiting.

RESULTS

Analgesia was necessary in 106 telemedically assisted missions. In 23 cases, the telemedical procedure was used until an EMS physician arrived. Of the remaining 83 cases, 80 could be matched to comparable controls. Complications did not occur in either the study group or the control group (0 vs. 0; p = N/A). Complete NRS documentation was noted in 65/80 (study group) and 32/80 (control group) cases (p < 0.0001). Adequate initial pain reduction (quality indicator: reduction of NRS ≥ 2 points or NRS < 5 at end of mission) occurred in 61/65 versus 31/32 cases (p = 1.0); NRS reduction during mission was 3.78 ± 2.0 versus 4.38 ± 2.2 points (p = 0.0159). Nausea and vomiting occurred with equal frequency in both groups.

CONCLUSIONS

Telemedical delegation of analgesics to paramedics was safe and led to a pain reduction superior to the published minimum standard in both groups. The documentation quality was better in the telemedicine group. WHAT DOES THIS STUDY ADD?: Little is known about the safety and quality of prehospital analgesia carried out by emergency medical services (EMS). Beside potential quality problems, in some countries meaningful pain reduction is limited by legal regulations that allow only physicians to administer analgesics. This first multicentre prospective trial for telemedically delegated analgesia demonstrates that remote analgesia is possible and safe and retains equivalent analgesic quality compared with that administered by onsite EMS physicians.
