Clinical Trial Summary

A broken hip occurs frequently in elderly patients and is often very painful. Side effects of inadequately treated pain as well as the traditional drugs (administered through intravenous catheter) used to treat pain are, among others, a confusional state, called delirium. When pain medication is administered locally, only around the hip joint, pain might be treated more effectively and these side effects could be prevented. This is called a nerve block. The current study evaluates the use of a continuous nerve block throughout the complete hospital admission with a catheter around the hip joint versus the use of traditionally used pain medication administered though an intravenous catheter in elderly patients with a broken hip. Half of all patients will receive the nerve block while in the emergency department and the other half will receive pain medication through the intravenous access.

Description:

BACKGROUND Hip fractures occur frequently and are usually very painful. Pain itself is an indicator for increased risk of complications. A significant complication is delirium, occurring in up to 25% of all elderly patients with hip fractures. For a large proportion, triggers for development of delirium reaches back to the preoperative phase, where polypharmacy (including opioid use) and inadequately treated pain are major risk factors. Delirium is associated with negative health consequences, increased hospital stay, falls, higher mortality, decreased physical and cognitive function, re-hospitalization, increased risk of dementia and increased societal costs. Therefore, pain should be optimally treated as soon as possible, however the elderly patient poses a challenge in good pain treatment, because of physiological age-related changes, different drug effects, distribution, metabolism and elimination. Opioids frequently lead to respiratory depression, hypotension, nausea/vomiting and sedation in this vulnerable patient group. As a consequence, these drugs are often under dosed and pain treated insufficiently. Besides, drugs as opioids and NSAIDs have been associated with an increased delirium risk. A nerve block could alleviate these clinical issues. An example of a nerve block frequently utilized in the Emergency Department (ED) is a Fascia Iliaca Compartment Block (FICB), in which local anesthetics are injected underneath the pelvic iliac fascia in order to block femoral, obturator and lateral cutaneous nerves to provide anesthesia of hip, thigh and knee. Case-series and historically controlled cohort studies show a single-shot FICB is a rapid, safe and easy procedure providing excellent analgesia, decreased opioid need and little risk of complications. Delirium as outcome was reported in one RCT; a decreased delirium incidence after using repetitive, blind, single-shot FICBs (not in the acute setting) with pethidine (with increased intrinsic risk of developing delirium) as comparison. In order to prevent the need for repetitive insertions, leaving a catheter would create a route in order to provide continuous analgesia with local anesthetics. Two case series describe this continuous FICB in hip fractures and reported good pain control and decreased length of hospital stay without any infectious complications. No comparison studies have been done with a continuous FICB. The objective of the current study is to investigate whether the use of a continuous FICB, started early (in the ED) and continued throughout the complete clinical course of a hip fracture, will decrease occurrence of delirium in elderly patients with hip fractures. METHODS This study is designed as a prospective, open, multi-center, randomized interventional trial. Patients will be allocated to continuous FICB or care as usual (according to national guidelines) in a 1:1 ratio and followed up until three months after hospital discharge. SAMPLE SIZE AND DATA ANALYSIS The primary outcome (occurrence of delirium) is expected to be distributed normally. Although evidence to prevent delirium is scarce, an absolute reduction of 13% incidence has been reported previously after an intervention. The estimated delirium incidence according to literature is 25%. The hypothesis is that by using a continuous FICB administered very early in the clinical course in the ED, the incidence can be decreased from 25 to 12%. Superiority of the FICB versus usual care will be tested using the Chi Square Test. In order to detect a clinically relevant between-group-difference of 13% decrease in incidence, a significance level of 0.05 and 80% power will be used. For this analysis, each group will have 154 patients. When accounting for 10% loss to follow-up after three months, a total study population of 340 will be needed. The primary analysis will be based on the intention to treat principle. Per protocol analysis will be performed to check robustness of results. Baseline characteristics will be presented using descriptive statistics. Ordinal data will be analyzed using Chi Square Test or Fisher exact test. Continuous data will be assessed by a Student's t-test if normally distributed or Mann Whitney U test if otherwise. Missing data will be corrected by multiple imputation. An economic evaluation will be performed focusing on possible gained benefits of pain management with a continuous FICB compared to care as usual and the related health care costs. The economic evaluation will be performed from a societal perspective with a time horizon of three months and capturing the value of all resources utilized. The economic evaluation will be set up as a Cost-Effectiveness Analysis (CEA). Besides a CEA, a Budget Impact Analysis (BIA) will be performed according to the ISPOR Task Force principles.
