Responsiveness of the EuroQol (EQ-5D) and the Nottingham Health Profile (NHP) in elderly patients with femoral neck fractures

Measurement properties of the EQ-5D in populations with a mean age of ≥ 75 years: a systematic review

PURPOSE

Healthcare interventions for middle-old and oldest-old individuals are often (economically) evaluated using the EQ-5D to measure health-related quality of life (HrQoL). This requires sufficient measurement properties of the EQ-5D. Therefore, the current study aimed to systematically review studies assessing the measurement properties of the EQ-5D in this population.

METHODS

The databases PubMed, Cochrane library, Web of Science, Embase, and EconLit were searched for studies providing empirical evidence of reliability, validity, and/or responsiveness of the EQ-5D-3L and EQ-5D-5L in samples with a mean age ≥ 75 years. Studies were selected by two independent reviewers, and the methodological quality was assessed using the COSMIN Risk of Bias checklist. Results were rated against updated criteria for good measurement properties (sufficient, insufficient, inconsistent, indeterminate). The evidence was summarized, and the quality of evidence was graded using a modified GRADE approach.

RESULTS

For both EQ-5D versions, high-quality evidence for sufficient convergent validity was found. Known-groups validity was sufficient for the EQ-5D-5L (high-quality evidence), whereas the results were inconsistent for the EQ-5D-3L. Results regarding the reliability were inconsistent (EQ-5D-3L) or entirely lacking (EQ-5D-5L). Responsiveness based on correlations of change scores with instruments measuring related/similar constructs was insufficient for the EQ-5D-3L (high-quality evidence). For the EQ-5D-5L, the available evidence on responsiveness to change in (Hr)QoL instruments was limited.

CONCLUSION

Since the responsiveness of the EQ-5D in a population of middle-old and oldest-old individuals was questionable, either using additional instruments or considering the use of an alternative, more comprehensive instrument of (Hr)QoL might be advisable, especially for economic evaluations.

Randomised controlled trial comparing intraoperative cell salvage and autotransfusion with standard care in the treatment of hip fractures: a protocol for the WHITE 9 study

INTRODUCTION

People who sustain a hip fracture are typically elderly, frail and require urgent surgery. Hip fracture and the urgent surgery is associated with acute blood loss, compounding patients' pre-existing comorbidities including anaemia. Approximately 30% of patients require a donor blood transfusion in the perioperative period. Donor blood transfusions are associated with increased rates of infections, allergic reactions and longer lengths of stay. Furthermore, there is a substantial cost associated with the use of donor blood. Cell salvage and autotransfusion is a technique that recovers, washes and transfuses blood lost during surgery back to the patient. The objective of this study is to determine the clinical and cost effectiveness of intraoperative cell salvage, compared with standard care, in improving health related quality-of-life of patients undergoing hip fracture surgery.

METHODS AND ANALYSIS

Multicentre, parallel group, two-arm, randomised controlled trial. Patients aged 60 years and older with a hip fracture treated with surgery are eligible. Participants will be randomly allocated on a 1:1 basis to either undergo cell salvage and autotransfusion or they will follow the standard care pathway. Otherwise, all care will be in accordance with the National Institute for Health and Care Excellence guidance. A minimum of 1128 patients will be recruited to obtain 90% power to detect a 0.075-point difference in the primary endpoint: EuroQol-5D-5L HRQoL at 4 months post injury. Secondary outcomes will include complications, postoperative delirium, residential status, mobility, allogenic blood use, mortality and resource use.

ETHICS AND DISSEMINATION

NHS ethical approval was provided on 14 August 2019 (19/WA/0197) and the trial registered (ISRCTN15945622). After the conclusion of this trial, a manuscript will be prepared for peer-review publication. Results will be disseminated in lay form to participants and the public.

Responsiveness of the Spanish Version of Newcastle Stroke-Specific Quality of Life Measure (NEWSQOL)

OBJECTIVE

To evaluate the responsiveness of the Spanish version of the Newcastle Stroke-specific Quality of Life measure (NEWSQOL) to assess quality of life in Spanish people after suffering a stroke.

DESIGN

A prospective observational study was conducted to assess the responsiveness of the Spanish version of NEWSQOL. The sample contained 128 patients who filled in the questionnaires before and after a physical therapy intervention. The responsiveness was assessed with p-values using the effect size (ES) and the standardized response means (SRMs) of the change. Besides, two other external criteria were used to distinguish patients who improved with the treatment from those who remained stable. This classification was based on one functional independence measure (the Barthel Index) and one disability measure (the modified Rankin Scale).

RESULTS

There was a statistically significant correlation (Spearman's coefficient = p < 0.01) between the domains of the Spanish version of NEWSQOL in relation to the Barthel Index and the modified Rankin Scale. All domains showed between marked-to-mild change responsiveness except sleep and relationships; mobility (ES 0.66 and SRM 0.92) and activities of daily living (ES 0.75 and SRM 0.87) were markedly responsive; communication (ES 0.38 and SRM 0.61) was moderately responsive; and pain, vision, cognition, feelings, emotions and fatigue were mildly responsive (ES 0.21-0.41 and SRM 0.23-0.44).

CONCLUSION

The Spanish version of NEWSQOL shows between marked and mild responsiveness to measure the perception of QoL in post-stroke patients. Therefore, its use can be suitable for evaluation studies, clinical trials and clinical practice.

Osteoporosis treatment rate following hip fracture in a community hospital

Treatment rates for osteoporosis after a major osteoporotic fracture are unacceptably low. We evaluate the effectiveness of an ortho-geriatric team (OGT) in initiating pharmacologic therapy for osteoporosis post-hip fracture. The OGT was able to achieve a higher treatment rate for patients post-hip fracture in comparison to usual care provided by the primary care hospitalist. Potential reasons for delaying or not proceeding with drug therapy include patient concern regarding potential rare side effects of antiresorptive therapy including osteonecrosis of the jaw and atypical femoral fracture. These events however are rare, and in this study, only 3% of hip fractures were atypical femoral fractures.

INTRODUCTION

Currently, a significant care gap for osteoporosis therapy exists post-hip fracture despite advances in pharmacologic therapy. We evaluate the effectiveness of the OGT at the Oakville Trafalgar Memorial Hospital (OTMH), Ontario, Canada, in reducing the care gap and initiating pharmacologic therapy in hip fracture patients prior to hospital discharge. We also evaluated the incidence of atypical femoral fracture (AFF) separately.

METHODS

A retrospective chart review of patients 59 years and older with a hip fracture admitted to OTMH from January 1, 2016, to February 1, 2017, was conducted. The primary outcome was the proportion of hip fracture patients discharged from the hospital with appropriate treatment for their underlying osteoporosis. A sub-analysis was completed reporting the incidence of AFF among older adults.

RESULTS

A total of 197 patients with a hip fracture were identified, 134/197 (68%) patients were seen by the OGT, 98/134 (73%) of these patients were started on pharmacologic therapy prior to discharge, and 120/134 (89%) of patients seen by the OGT were on treatment within 3 months of discharge following assessment in the complex osteoporosis clinic. Sixty-three patients of the 197 (63/197) (32%) of the hip fracture patients were seen by a hospitalist, and treatment rates prior to discharge were 5%. Only 6/197 patients had experienced an AFF during the study period, and all patients with an atypical femoral fracture had been on long-term bisphosphonate therapy. All of the patients with an AFF had thigh or groin pain for several weeks to months prior to the development of the atypical femoral fracture, providing an opportunity to stop therapy and possibly prevent the development of a complete AFF.

CONCLUSION

The OGT was able to initiate anti-osteoporosis therapy in significantly more patients in comparison to usual care, and higher treatment rates are possible with an OGT.

Large head ceramic-on-ceramic bearing in primary total hip arthroplasty: average 3-year follow-up of a multicentre study

BACKGROUND

Surgeons are increasingly using larger femoral head sizes in total hip arthroplasty (THA) to improve stability and reduce the rate of dislocation, 1 of the leading causes of revision surgery. Large ceramic head sizes up to 48 mm can now be used with monoblock acetabular components. National registries have shown promising results at short-term with large diameter ceramic-on-ceramic THA, with very low revision rates.This study reports on the average 3-year follow up of a press-fit monoblock large diameter acetabular shell with a pre-assembled ceramic liner, with emphasis on the radiographic outcome, complications related to the implantation of the cup, and the patient's clinical outcome.

METHODS

170 hips in 169 patients were reviewed at an average 38 ± 5.8 months following surgery.

RESULTS

The radiographic review revealed no acetabular cup loosening, no osteolysis and no cup migration. 1 acetabular cup was revised for malposition. The patient clinical outcome and the satisfaction rate were excellent. At 3 years, 7.1% of patients complained of groin pain and 3.5% spontaneously reported hip joint generated noise. 1 patient sustained a non-recurrent traumatic hip dislocation 2 years post surgery.

CONCLUSIONS

New technology should be introduced cautiously on the market. This is especially true for the large diameter ceramic monoblock acetabular component used in this study since it involves a new acetabular component design. At short term, we have not identified new modes of failure with this implant. Longer follow-up is still needed to assess the safety of large ceramic bearing in THA.

Correlation between Health-Related Quality of Life and Hand Grip Strength among Older Adults

Background: With advanced age, the progressive loss of muscle strength estimated by the handgrip strength (HGS) may result in a poorer health-related quality of life (HRQoL). Studying this association becomes a vital area of research for promoting aging-well. The aim of this study was to examine the correlation between HRQoL and HGS among community-dwelling older adults above 60 years old.Methods: Participants comprised of 176 older adults (mean age: 68.15 ± 6.74). The HGS was tested with Jamar® Dynamometer, and the EuroQuol-5 Dimensions 5Levels (EQ-5D-5L) questionnaire was used to assess HRQoL.Results: Both HGS and HRQoL were negatively correlated with age (p < .001). Lower values of HGS and HRQoL were recorded among older adults who had diagnosed with one or more chronic diseases (p < .001). Significant correlations were recorded between HGS and functioning, and subjective well-being domains of EQ-5D-5L. A relatively higher association was recorded between the functioning variables of EQ-5D-5L and HGS compared to subjective well- being variables.Conclusion: Handgrip strength is a simple and practical measure in identifying older adults at risk of physical decline. Maintaining handgrip strength may contribute to improving HRQoL, and can add an imperative dimension to promote aging-well in older adults ≥60 years old.

Preliminary effect and feasibility of physiotherapy with strength training and protein-rich nutritional supplement in combination with anabolic steroids in cross-continuum rehabilitation of patients with hip fracture: protocol for a blinded randomized controlled pilot trial (HIP-SAP1 trial)

BACKGROUND

A 2014 Cochrane review evaluating the effect of anabolic steroids after hip fracture concluded that the quality of the studies was insufficient to draw conclusions on the effects and recommended further high-quality trials in the field. Therefore, the aim of this pilot trial is to determine the preliminary effect and feasibility of a 12-week multimodal intervention consisting of physiotherapy (with strength training), protein-rich nutritional supplement and anabolic steroid on knee-extension muscle strength and function 14 weeks after hip fracture surgery.

METHODS

We plan to conduct a randomized, placebo-controlled pilot trial with 48 patients operated for acute hip fracture. The patients are randomized (1:1) to either (1) physiotherapy with protein-rich nutritional supplement plus anabolic steroid or (2) physiotherapy with protein-rich nutritional supplement plus placebo. Outcome assessments will be carried out blinded at baseline (3-10 days after surgery) and at 14 weeks after entering the trial. Primary outcome is the change from baseline to follow-up in maximal isometric knee-extension muscle strength in the fractured limb. Secondary outcomes are physical performance test, patient-reported outcomes, and measures of body composition.

DISCUSSION

If the trial is found feasible and the results show an indication of anabolic steroid being a relevant addition to further enhance the recovery of muscle strength and function in an enhanced recovery after surgery program, this trial will constitute the basis of a larger confirmatory trial.

Randomised controlled trial comparing hydroxyapatite coated uncemented hemiarthroplasty with cemented hemiarthroplasty for the treatment of displaced intracapsular hip fractures: a protocol for the WHITE 5 study

INTRODUCTION

Hip fracture is a serious injury in adults, especially those aged over 60 years. The most common type of hip fracture (displaced intracapsular) is treated for the majority of patients with a partial hip replacement (hemiarthroplasty). The hemiarthroplasty implant can be fixed to the bone with or without bone cement. Cement is the current recommended technique but recently some risks have been identified, which could potentially be avoided by using uncemented implants. Controversy, therefore, remains about which type of hemiarthroplasty offers patients the best outcomes.This is the protocol for a multicentre randomised controlled trial comparing cemented hemiarthroplasty versus uncemented hemiarthroplasty for patients 60 years and over with a displaced intracapsular hip fracture.

METHODS AND ANALYSIS

Multicentre (a minimum of seven UK hospitals), multisurgeon, parallel group, two-arm, superiority, randomised controlled trial. Patients aged 60 years and older with a displaced intracapsular hip fracture treated with hemiarthroplasty surgery are eligible. Participants will be randomly allocated on a 1:1 basis to either a cemented hemiarthroplasty or a modern hydroxyapatite coated uncemented hemiarthroplasty. Otherwise all care will be in accordance with the National Institute for Health and Care Excellence guidance. A minimum of 1128 patients will be recruited to obtain 90% power to detect a 0.075-point difference in the primary endpoint: health-related quality of life (EuroQol 5 dimensions 5 levels) at 4 months postinjury. The treatment effect will be estimated using a two-sided t-test adjusted for age, gender and cognitive impairment based on an intention-to-treat analysis. Secondary outcomes include mortality, complications including revision surgery and cause, mobility status, residential status, health-related quality of life at 1 and 12 months and health resource use. A within-trial economic analysis will be conducted.

ETHICS, DISSEMINATION AND FUNDING

Wales Research Ethics Committee 5 approved the feasibility phase on 2 December 2016 (16/WA/0351) and the definitive trial on 22 November 2017 (17/WA/0383). This study is sponsored by the University of Oxford and funded by the National Institute for Health Research, Research for Patient Benefit (PB-PG-0215-36043 and PB-PG-1216-20021). A manuscript for a peer-reviewed journal will be prepared and the results shared with patients via local mechanisms at participating centres.

Evaluation of RESPOND, a patient-centred program to prevent falls in older people presenting to the emergency department with a fall: A randomised controlled trial

BACKGROUND

Falls are a leading reason for older people presenting to the emergency department (ED), and many experience further falls. Little evidence exists to guide secondary prevention in this population. This randomised controlled trial (RCT) investigated whether a 6-month telephone-based patient-centred program-RESPOND-had an effect on falls and fall injuries in older people presenting to the ED after a fall.

METHODS AND FINDINGS

Community-dwelling people aged 60-90 years presenting to the ED with a fall and planned for discharge home within 72 hours were recruited from two EDs in Australia. Participants were enrolled if they could walk without hands-on assistance, use a telephone, and were free of cognitive impairment (Mini-Mental State Examination > 23). Recruitment occurred between 1 April 2014 and 29 June 2015. Participants were randomised to receive either RESPOND (intervention) or usual care (control). RESPOND comprised (1) home-based risk assessment; (2) 6 months telephone-based education, coaching, goal setting, and support for evidence-based risk factor management; and (3) linkages to existing services. Primary outcomes were falls and fall injuries in the 12-month follow-up. Secondary outcomes included ED presentations, hospital admissions, fractures, death, falls risk, falls efficacy, and quality of life. Assessors blind to group allocation collected outcome data via postal calendars, telephone follow-up, and hospital records. There were 430 people in the primary outcome analysis-217 randomised to RESPOND and 213 to control. The mean age of participants was 73 years; 55% were female. Falls per person-year were 1.15 in the RESPOND group and 1.83 in the control (incidence rate ratio [IRR] 0.65 [95% CI 0.43-0.99]; P = 0.042). There was no significant difference in fall injuries (IRR 0.81 [0.51-1.29]; P = 0.374). The rate of fractures was significantly lower in the RESPOND group compared with the control (0.05 versus 0.12; IRR 0.37 [95% CI 0.15-0.91]; P = 0.03), but there were no significant differences in other secondary outcomes between groups: ED presentations, hospitalisations or falls risk, falls efficacy, and quality of life. There were two deaths in the RESPOND group and one in the control group. No adverse events or unintended harm were reported. Limitations of this study were the high number of dropouts (n = 93); possible underreporting of falls, fall injuries, and hospitalisations across both groups; and the relatively small number of fracture events.

CONCLUSIONS

In this study, providing a telephone-based, patient-centred falls prevention program reduced falls but not fall injuries, in older people presenting to the ED with a fall. Among secondary outcomes, only fractures reduced. Adopting patient-centred strategies into routine clinical practice for falls prevention could offer an opportunity to improve outcomes and reduce falls in patients attending the ED.

Liberal transfusion strategy to prevent mortality and anaemia-associated, ischaemic events in elderly non-cardiac surgical patients - the study design of the LIBERAL-Trial

Background

Perioperative anaemia leads to impaired oxygen supply with a risk of vital organ ischaemia. In healthy and fit individuals, anaemia can be compensated by several mechanisms. Elderly patients, however, have less compensatory mechanisms because of multiple co-morbidities and age-related decline of functional reserves. The purpose of the study is to evaluate whether elderly surgical patients may benefit from a liberal red blood cell (RBC) transfusion strategy compared to a restrictive transfusion strategy.

Methods

The LIBERAL Trial is a prospective, randomized, multicentre, controlled clinical phase IV trial randomising 2470 elderly (≥ 70 years) patients undergoing intermediate- or high-risk non-cardiac surgery. Registered patients will be randomised only if Haemoglobin (Hb) reaches ≤9 g/dl during surgery or within 3 days after surgery either to the LIBERAL group (transfusion of a single RBC unit when Hb ≤ 9 g/dl with a target range for the post-transfusion Hb level of 9–10.5 g/dl) or the RESTRICTIVE group (transfusion of a single RBC unit when Hb ≤ 7.5 g/dl with a target range for the post-transfusion Hb level of 7.5–9 g/dl). The intervention per patient will be followed until hospital discharge or up to 30 days after surgery, whichever occurs first. The primary efficacy outcome is defined as a composite of all-cause mortality, acute myocardial infarction, acute ischaemic stroke, acute kidney injury (stage III), acute mesenteric ischaemia and acute peripheral vascular ischaemia within 90 days after surgery. Infections requiring iv antibiotics with re-hospitalisation are assessed as important secondary endpoint. The primary endpoint will be analysed by logistic regression adjusting for age, cancer surgery (y/n), type of surgery (intermediate- or high-risk), and incorporating centres as random effect.

Discussion

The LIBERAL-Trial will evaluate whether a liberal transfusion strategy reduces the occurrence of major adverse events after non-cardiac surgery in the geriatric population compared to a restrictive strategy within 90 days after surgery.

Reducing Implant Infection in Orthopaedics (RIIiO): a pilot study for a randomised controlled trial comparing the influence of forced air versus resistive fabric warming technologies on postoperative infection rates following orthopaedic implant surgery in adults

Background

Approximately 70,000 to 75,000 proximal femoral fracture repairs take place in the UK each year. Hemiarthroplasty is the preferred treatment for adults aged over 60 years. Postoperative infection affects up to 3% of patients and is the single most common reason for early return to theatre. Ultraclean ventilation was introduced to help mitigate the risk of infection, but it may also contribute to inadvertent perioperative hypothermia, which itself is a risk for postoperative infection. To counter this, active intraoperative warming is used for all procedures that take 30 min or more. Forced air warming (FAW) and resistive fabric warming (RFW) are the two principal techniques used for this purpose; they are equally effective in prevention of inadvertent perioperative hypothermia, but it is not known which is associated with the lowest infection rates. Deep surgical site infection doubles operative costs, triples investigation costs and quadruples ward costs. The Reducing Implant Infection in Orthopaedics (RIIiO) study seeks to compare infection rates with FAW versus RFW after hemiarthroplasty for hip fracture. A cost-neutral intervention capable of reducing postoperative infection rates would likely lead to a change in practice, yield significant savings for the health economy, reduce overall exposure to antibiotics and improve outcomes following hip fracture in the elderly. The findings may be transferable to other orthopaedic implant procedures and to non-orthopaedic surgical specialties.

Methods

RIIiO is a parallel group, open label study randomising hip fracture patients over 60 years of age who are undergoing hemiarthroplasty to RFW or FAW. Participants are followed up for 3 months. Definitive deep surgical site infection within 90 days of surgery, the primary endpoint, is determined by a blinded endpoint committee.

Discussion

Hemiarthroplasty carries a risk of deep surgical site infection of approximately 3%. In order to provide 90% power to demonstrate an absolute risk reduction of 1%, using a 5% significance level, a full trial would need to recruit approximately 8630 participants. A pilot study is being conducted in the first instance to demonstrate that recruitment and data management strategies are appropriate and robust before embarking on a large multi-centre trial.

Characteristics of recurrent fractures

The present study, drawn from a sample of the Icelandic population, quantified high immediate risk and utility loss of subsequent fracture after a sentinel fracture (at the hip, spine, distal forearm and humerus) that attenuated with time.

INTRODUCTION

The risk of a subsequent osteoporotic fracture is particularly acute immediately after an index fracture and wanes progressively with time. The aim of this study was to quantify the risk and utility consequences of subsequent fracture after a sentinel fracture (at the hip, spine, distal forearm and humerus) with an emphasis on the time course of recurrent fracture.

METHODS

The Reykjavik Study fracture registration, drawn from a sample of the Icelandic population (n = 18,872), recorded all fractures of the participants from their entry into the study until December 31, 2012. Medical records for the participants were manually examined and verified. First sentinel fractures were identified. Subsequent fractures, deaths, 10-year probability of fracture and cumulative disutility using multipliers derived from the International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) were examined as a function of time after fracture, age and sex.

RESULTS

Over 10 years, subsequent fractures were sustained in 28% of 1498 individuals with a sentinel hip fracture. For other sentinel fractures, the proportion ranged from 35 to 38%. After each sentinel fracture, the risk of subsequent fracture was highest in the immediate post fracture interval and decreased markedly with time. Thus, amongst individuals who sustained a recurrent fracture, 31-45% did so within 1 year of the sentinel fracture. Hazard ratios for fracture recurrence (population relative risks) were accordingly highest immediately after the sentinel fracture (2.6-5.3, depending on the site of fracture) and fell progressively over 10 years (1.5-2.2). Population relative risks also decreased progressively with age. The utility loss during the first 10 years after a sentinel fracture varied by age (less with age) and sex (greater in women). In women at the age of 70 years, the mean utility loss due to fractures in the whole cohort was 0.081 whereas this was 12-fold greater in women with a sentinel hip fracture, and was increased 15-fold for spine fracture, 4-fold for forearm fracture and 8-fold for humeral fracture.

CONCLUSION

High fracture risks and utility loss immediately after fracture suggest that treatment given as soon as possible after fracture would avoid a higher number of new fractures compared with treatment given later. This provides the rationale for very early intervention immediately after a sentinel fracture.

Quality of life for up to 18 months after low-energy hip, vertebral, and distal forearm fractures-results from the ICUROS

This study used data from the International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) to estimate the quality of life (QoL) impact of fracture. Hip, vertebral, and distal forearm fractures incur substantial QoL losses. Hip and vertebral fracture results in markedly impaired QoL for at least 18 months.

INTRODUCTION

The International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) is a multinational observational study that aims to describe costs and quality of life (QoL) consequences of osteoporotic fractures. To date, 11 countries have participated in the study: Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain, the UK, and the USA. The objective of this paper is to describe the QoL impact of hip, vertebral, and distal forearm fracture.

METHODS

Data were collected at four time-points for five QoL point estimates: within 2 weeks after fracture (including pre-fracture recall) and at 4, 12, and 18 months after fracture. Quality of life was measured as health state utility values (HSUVs) derived from the EQ-5D-3L. Complete case analysis was conducted as the base case with available case and multiple imputation performed as sensitivity analyses. Multivariate analysis was performed to explore predictors of QoL impact of fracture.

RESULTS

Among 5456 patients enrolled using convenience sampling, 3021 patients were eligible for the base case analysis (1415 hip, 1047 distal forearm, and 559 vertebral fractures). The mean (SD) difference between HSUV before and after fracture for hip, vertebral, and distal forearm fracture was estimated at 0.89 (0.40), 0.67 (0.45), and 0.48 (0.34), respectively (p < 0.001 for all fracture types). Eighteen months after fracture, mean HSUVs were lower than before the fracture in patients with hip fracture (0.66 vs. 0.77 p < 0.001) and vertebral fracture (0.70 vs. 0.83 p < 0.001). Hospitalization and higher recalled pre-fracture QoL were associated with increased QoL impact for all fracture types.

CONCLUSIONS

Hip, vertebral, and distal forearm fractures incur substantial loss in QoL and for patients with hip or vertebral fracture, QoL is markedly impaired for at least 18 months.

RESPOND: a programme to prevent secondary falls in older people presenting to the emergency department with a fall: protocol for an economic evaluation

BACKGROUND

Falls remain common for community-dwelling older people and impose a substantial economic burden to the healthcare system. RESPOND is a novel falls prevention programme that aims to reduce secondary falls and fall injuries among older people who present to a hospital emergency department (ED) with a fall. The present protocol describes a prospective economic evaluation examining the incremental cost-effectiveness of the RESPOND programme, compared with usual care practice, from the Australian health system perspective.

METHODS AND DESIGN

This economic evaluation will recruit 528 participants from two major tertiary hospital EDs in Australia and will be undertaken alongside a multisite randomised controlled trial. Outcome and costing data will be collected for all participants over the 12-month trial. It will compare the RESPOND falls prevention programme with usual care practice (current community-based falls prevention practices) to determine its incremental cost-effectiveness according to three intermediate clinical outcomes: (1) falls prevented, (2) fall injuries prevented and (3) injurious falls prevented. In addition, utilities will be derived from a generic quality-of-life measure (EQ-5D-5L) and used to calculate the 'incremental cost per quality-adjusted life years gained'.

DISCUSSION

The results of this study will provide healthcare decision makers with evidence to assist with setting spending thresholds for preventive health programmes and inform selection of emergency and community service models of care.

Good responsiveness with EuroQol 5-Dimension questionnaire and Short Form (36) Health Survey in 20-69 years old patients with a femoral neck fracture: A 2-year prospective follow-up study in 182 patients

BACKGROUND

EQ-5D and SF-36 are two questionnaires used to measure health related quality of life (HRQoL). The responsiveness of these instruments has previously been evaluated in elderly populations with hip fracture but not in a younger population. The purpose was to evaluate the responsiveness of SF-36 and EQ-5D in a younger population with femoral neck fracture.

METHODS

182 patients aged 20-69 were consecutively included. HRQoL was measured by EQ-5D and SF-36 at 4, 12 and 24 months. Pain and function were measured by Harris Hip Score (HHS) on the same occasions. The responsiveness of EQ-5D and SF-36 was evaluated by calculation of two effect sizes; standardized effect size (SES) and standardized response mean (SRM), and by analysing how changes in score correlated to changes in function and subjective state of health. External responsiveness was also evaluated by calculating receiver operating characteristic curve and area under the curve.

RESULTS

SES was large at four months for both EQ-5D and SF-36 (1.09 and 0.83 respectively) and moderate at the 12- and 24-month follow-ups. The correlation between changes (4-24 months) in HHS and changes in HRQoL were 0.44 for EQ-5D and 0.37 for SF-36. EQ-5D and SF-36 were both more sensitive than HHS in their ability to predict subjective improvements after a hip fracture.

CONCLUSIONS

The effect sizes and the ability to follow and predict the external standard indicates that both EQ-5D and SF-36 have good internal and external responsiveness in this younger population with femoral neck fracture. The generic HRQoL questionnaires were superior to a hip-specific instrument in predicting the patients' subjective feelings of an improved state of health. EQ-5D is simple to administer and shows similar responsiveness as SF-36 and may be sufficient to use as an outcome measure in clinical trials.

Quality of life following hip fractures: results from the Norwegian hip fracture register

BACKGROUND

Patient-reported health-related quality of life is an important outcome measure when assessing the quality of hip fracture surgery. The frequently used EQ-5D index score has unfortunately important limitations. One alternative can be to assess the distribution of each of the five dimensions of the patients' descriptive health profile. The objective of this paper was to investigate health-related quality of life (HRQoL) after hip fractures.

METHODS

Data from hip fracture operations from 2005 through 2012 were obtained from The Norwegian Hip Fracture Register. Patient reported HRQoL, (EQ-5D-3L) was collected from patients preoperatively and at four and twelve months postoperatively n = 10325. At each follow-up the distribution of the EQ-5D-3L and mean pain VAS was calculated.

RESULTS

Generally, a higher proportion of patients reported problems in all 5 dimensions of the EQ-5D-3L at all follow-ups compared to preoperative. Also a high proportion of patients with no preoperative problems reported problems after surgery; At 4 and 12 months follow-ups 71 % and 58 % of the patients reported walking problems, and 65 % and 59 % of the patients reported pain respectively. Patients with femoral neck fractures and the youngest patients (age < 70 years) reported least problems both preoperatively and at all follow-ups.

CONCLUSIONS

A hip fracture has a dramatic impact on the patients' HRQoL, and the deterioration in HRQoL sustained also one year after the fracture. Separate use of the descriptive profile of the EQ-5D is informative when assessing quality of life after hip fracture surgery.

Can The EQ-5D Detect Meaningful Change? A Systematic Review

BACKGROUND

The EQ-5D is one of the most frequently used, generic, preference-based instruments for measuring the health utilities of patients in economic evaluations. It is recommended for health technology assessment by the National Institute for Health and Clinical Excellence. Because the EQ-5D plays such an important role in economic evaluations, useful information on its responsiveness to detect meaningful change in health status is required.

OBJECTIVE

This study systematically reviewed and synthesized evidence on the responsiveness of the EQ-5D to detect meaningful change in health status for clinical research and economic evaluations.

METHODS

We searched the EuroQol website, PubMed, PsychINFO, and EconLit databases to identify studies published in English from the inception of the EQ-5D until August 15, 2014 using keywords that were related to responsiveness. Studies that used only the EQ-VAS were excluded from the final analysis. Narrative synthesis was conducted to summarize evidence on the responsiveness of the EQ-5D by conditions or physiological functions.

RESULTS

Of 1401 studies, 145 were included in the narrative synthesis and categorized into 19 categories for 56 conditions. The EQ-5D was found to be responsive in 25 conditions (45 %) with the magnitude of responsiveness varying from small to large depending on the condition. There was mixed evidence of responsiveness in 27 conditions (48 %). Only four conditions (7 %) (i.e., alcohol dependency, schizophrenia, limb reconstruction, and hearing impairment) were identified where the EQ-5D was not responsive.

CONCLUSION

The EQ-5D is an appropriate measure for economic evaluation and health technology assessment in conditions where it has demonstrated evidence of responsiveness. In conditions with mixed evidence of responsiveness, researchers should consider using the EQ-5D with other condition-specific measures to ensure appropriate estimates of effectiveness. These conditions should be a main focus for future research using the new EQ-5D version with five response levels.

Physical Activity and Health-Related Quality of Life Among Community Dwelling Elderly

BACKGROUND

Physical activity (PA) and health-related quality of life (HRQoL) are important factors for optimal health in the elderly. Studying the association between PA and HRQoL is becoming more essential as the number of elderly people increases worldwide. This study assesses the association between PA and HRQoL among community dwelling elderly above 60 years old.

METHODS

The study included 115 women and 61 men (mean age: 68.15 ± 6.74 years) recruited from the community and from public centers for the elderly. Data were collected using a background characteristics questionnaire (BCQ), a physical activity socio-cultural adapted questionnaire (PA-SCAQ), and the EuroQuol-5Dimensions-5Levels (EQ-5D-5L) questionnaire. Between groups, comparisons were based on the PA-SCAQ by dividing the participants into three PA groups: low (n = 74), moderate (n = 85), and high (n = 17). Kruskal-Wallis tests were performed on the ordinal variables of the three PA groups to determine differences between the groups according to categorical variables such as gender, body mass index (BMI), and the prevalence of comorbid conditions. Mann-Whitney U tests were performed on the ordinal variables of the EuroQuol-5Dimensions (EQ-5D), and the independent sample t-test was performed on the EQ visual analogue scale (EQ-VAS). Spearman's rank correlation coefficient was used to examine the correlation between the EQ-5D and level of PA.

RESULTS

Values in all dimensions of HRQoL were significantly higher (P < 0.05) in the moderate and high PA groups compared with the low PA group. Significant correlations were recorded between the five dimensions of HRQoL and the level of PA (P < 0.001). The low PA group showed higher prevalence of hypertension (64%, P < 0.001) and diabetes (50%, P < 0.001).

CONCLUSION

There were strong associations between higher levels of PA and all dimensions of HRQoL. Therefore, adopting a PA lifestyle may contribute to better HRQoL among community dwelling elderly above 60 years old.

Hip fracture surgery: improving the quality of the evidence base

Hip fracture is a common injury associated with high mortality, long-term disability and huge socio-economic burden. Yet there has been relatively little research into best treatment, and evidence that has been generated has often been criticised for its poor quality. Here, we discuss the advances made towards overcoming these criticisms and the future directions for hip fracture research: how co-ordinating existing national infrastructures and use of now established clinical research networks will likely go some way towards overcoming the practical and financial challenges of conducting large trials. We highlight the importance of large collaborative pragmatic trials to inform decision/policy makers and the progress made towards reaching a consensus on a core outcome set to facilitate data pooling for evidence synthesis and meta-analysis. These advances and future directions are a priority in order to establish the high-quality evidence base required for this important group of patients.

Responsiveness of the EQ-5D to clinical change: is the patient experience adequately represented?

OBJECTIVES

In many economic evaluations and reimbursement decisions, quality-adjusted life-years (QALYs) are used as a measure of benefit to assess effectiveness of novel therapies, often based on the EQ-5D 3-level questionnaire. As only five dimensions of physical and mental well-being are reflected in this tool, significant aspects of the patient experience may be missed. We evaluate the use of the EQ-5D as a measurement of clinical change across a wide range of disorders from dermatological (acne) to life-threatening (metastatic cancers).

METHODS

We analyze published studies on the psychometric properties of the EQ-5D 3-level questionnaire, extracting information on the Visual Analogue Scale versus Index score, Standardized Response Mean, and Effect Size. These are compared with ranges generally accepted to represent good responsiveness in the psychometric literature.

RESULTS

We find that only approximately one in five study populations report subjective health state valuation of patients within 5 percent of the score attributed by the EQ-5D index, and more than 40 percent of studies report unacceptable ceiling effects. In the majority of studies, responsiveness of the EQ-5D index was found to be poor to moderate, based on Effect Size (63 percent poor–moderate) and Standardized Response Mean (72 percent poor–moderate).

CONCLUSIONS

We conclude that the EQ-5D index does not adequately reflect patient health status across a range of conditions, and it is likely that a significant proportion of the subjective patient experience is not accounted for by the index. This has implications for economic evaluations of novel drugs based on evidence generated with the EQ-5D.

Mapping the Nottingham Health Profile onto the Preference-Based EuroQol-5D Instrument for Patients with Diabetes

OBJECTIVE

The aim of this study was to derive a function that can map the Nottingham Health Profile (NHP) questionnaire onto a utility measure, the EuroQol five-dimensional (EQ-5D) questionnaire index, for diabetic patients.

METHODS

A cross-sectional study was performed on diabetic patients in Hungary with different complications in which quality of life was measured by using both the NHP questionnaire and the EQ-5D questionnaire. Ordinary stepwise-backward least-squares regression was used to develop a mapping function. Adjusted R², Akaike's information criterion, and root mean square error were used to assess the performance of the model. The robustness of the models was tested using 10-fold cross-validation and bootstrapping.

RESULTS

The best-fitting models were those that contained all the NHP statements as predictors and a stepwise reduced version that contained only 19 statements. The latter model, however, showed considerable variability in the selection of predictors. The adjusted R² of the former model was 0.68, the root mean square error was 174, and the Akaike's information criterion was -559.9.

CONCLUSIONS

The expected value of the EQ-5D questionnaire can be reasonably predicted on the basis of results of the NHP in patients with diabetes mellitus. The mapping function of the NHP onto the EQ-5D questionnaire is capable of estimating the expected EQ-5D questionnaire utility values in a group of patients with diabetes. The function's applicability for individual-level predictions, however, is limited. Further research is needed to find out whether mapping functions developed in Central-Eastern European countries are transferable to Western European countries.

RESPOND--A patient-centred programme to prevent secondary falls in older people presenting to the emergency department with a fall: protocol for a multicentre randomised controlled trial

INTRODUCTION

Participation in falls prevention activities by older people following presentation to the emergency department (ED) with a fall is suboptimal. This randomised controlled trial (RCT) will test the RESPOND programme, an intervention designed to improve older persons' participation in falls prevention activities through delivery of patient-centred education and behaviour change strategies.

DESIGN AND SETTING

A RCT at two tertiary referral EDs in Melbourne and Perth, Australia.

PARTICIPANTS

528 community-dwelling people aged 60-90 years presenting to the ED with a fall and discharged home will be recruited. People who require an interpreter or hands-on assistance to walk; live in residential aged care or >50 km from the trial hospital; have terminal illness, cognitive impairment, documented aggressive behaviour or a history of psychosis; are receiving palliative care or are unable to use a telephone will be excluded.

METHODS

Participants will be randomly allocated to the RESPOND intervention or standard care control group. RESPOND incorporates (1) a home-based risk factor assessment; (2) education, coaching, goal setting and follow-up telephone support for management of one or more of four risk factors with evidence of effective interventions and (3) healthcare provider communication and community linkage delivered over 6 months. Primary outcomes are falls and fall injuries per person-year.

DISCUSSION

RESPOND builds on prior falls prevention learnings and aims to help individuals make guided decisions about how they will manage their falls risk. Patient-centred models have been successfully trialled in chronic and cardiovascular disease; however, evidence to support this approach in falls prevention is limited.

TRIAL REGISTRATION NUMBER

The protocol for this study is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12614000336684).

Outcome assessment after hip fracture: is EQ-5D the answer?

Objectives

To study the measurement properties of a joint specific patient reported outcome measure, a measure of capability and a general health-related quality of life (HRQOL) tool in a large cohort of patients with a hip fracture.

Methods

Responsiveness and associations between the Oxford Hip Score (a hip specific measure: OHS), ICEpop CAPability (a measure of capability in older people: ICECAP-O) and EuroQol EQ-5D (general health-related quality of life measure: EQ-5D) were assessed using data available from two large prospective studies. The three outcome measures were assessed concurrently at a number of fixed follow-up time-points in a consecutive sequence of patients, allowing direct assessment of change from baseline, inter-measure associations and validity using a range of statistical methods.

Results

ICECAP-O was not responsive to change. EQ-5D was responsive to change from baseline, with an estimated standardised effect size for the two datasets of 0.676 and 0.644 at six weeks and four weeks respectively; this was almost as responsive to change as OHS (1.14 at four weeks). EQ-5D correlated strongly with OHS; Pearson correlation coefficients were 0.74, 0.77 and 0.70 at baseline, four weeks and four months. EQ-5D is a moderately good predictor of death at 12 months following hip fracture. Furthermore, EQ-5D reported by proxies (relatives and carers) behaves similarly to self-reported scores.

Conclusions

Our findings suggest that a general HRQOL tool such as EQ-5D could be used to measure outcome for patients recovering from hip fracture, including those with cognitive impairment.

Identifying a standard set of outcome parameters for the evaluation of orthogeriatric co-management for hip fractures

BACKGROUND AND PURPOSE

Osteoporotic fractures are an increasing problem in the world due to the ageing of the population. Different models of orthogeriatric co-management are currently in use worldwide. These models differ for instance by the health-care professional who has the responsibility for care in the acute and early rehabilitation phases. There is no international consensus regarding the best model of care and which outcome parameters should be used to evaluate these models. The goal of this project was to identify which outcome parameters and assessment tools should be used to measure and compare outcome changes that can be made by the implementation of orthogeriatric co-management models and to develop recommendations about how and when these outcome parameters should be measured. It was not the purpose of this study to describe items that might have an impact on the outcome but cannot be influenced such as age, co-morbidities and cognitive impairment at admission.

METHODS

Based on a review of the literature on existing orthogeriatric co-management evaluation studies, 14 outcome parameters were evaluated and discussed in a 2-day meeting with panellists. These panellists were selected based on research and/or clinical expertise in hip fracture management and a common interest in measuring outcome in hip fracture care.

RESULTS

We defined 12 objective and subjective outcome parameters and how they should be measured: mortality, length of stay, time to surgery, complications, re-admission rate, mobility, quality of life, pain, activities of daily living, medication use, place of residence and costs. We could not recommend an appropriate tool to measure patients' satisfaction and falls. We defined the time points at which these outcome parameters should be collected to be at admission and discharge, 30 days, 90 days and 1 year after admission.

CONCLUSION

Twelve objective and patient-reported outcome parameters were selected to form a standard set for the measurement of influenceable outcome of patients treated in different models of orthogeriatric co-managed care.

Musculoskeletal function and quality of life after an unstable trochanteric fracture treated with the trochanteric gamma nail

PURPOSE

The aim of the study was to report the musculoskeletal function and health-related quality of life (HRQoL) after an unstable trochanteric fracture treated with a cephalomedullary nail.

METHODS

One hundred and seventeen patients, mean age 84.1 years, were included in a 1-year prospective cohort study. Outcome measurements included musculoskeletal function according to the Short Musculoskeletal Function Assessment (SMFA) and HRQoL according to the EQ-5D.

RESULTS

Fourteen patients (12.0 %) were reoperated on, all but one being due to a secondary lag-screw penetration/cut-out. The need for revision surgery was significantly higher after a 4-part fracture according to the Jensen-Michaelsen classification as compared to after a 3-part fracture, i.e. 17 versus 6 % (p = 0.048). The reoperation was a hip replacement in 12 of the 14 patients, a total hip replacement (THR) in 10 and a hemiarthroplasty in 2. The SMFA dysfunction and bother indices in all patients showed a significant deterioration at 12 months compared to before the fracture, from 24.8 to 42.4 (p < 0.001) and 14.3 to 33.7 (p < 0.001), respectively. The EQ-5D(index) score decreased from 0.79 prefracture to 0.51 (p < 0.001). The final outcome for the patients who underwent reoperation with THR was surprisingly good with an SMFA dysfunction index of 43.4, a bother index of 36.6 and an EQ-5D(index) score of 0.58.

CONCLUSIONS

An unstable trochanteric fracture treated with a cephalomedullary nail had a substantial negative impact on the patient's musculoskeletal function and HRQoL. The need for revision surgery was significantly higher after a 4-part fracture compared to after a 3-part fracture. The by far most common fracture complication, i.e. a secondary lag-screw penetration/cut-out, was successfully treated with a THR.

Measures of physical functioning after hip fracture: construct validity and responsiveness of performance-based and self-reported measures

OBJECTIVES

this study aimed to investigate the construct validity and responsiveness of performance-based and self-reported measures of strength, mobility and balance after hip fracture.

DESIGN

secondary analysis of clinical trial data.

SUBJECTS

a total of 148 older people undergoing hip fracture rehabilitation.

METHODS

correlation coefficients assessed construct validity. Internal responsiveness was assessed by calculating effect sizes (ES) I and II. Area under the receiver operating characteristic curve (AUC) assessed external responsiveness with change in EuroQol as the reference.

RESULTS

correlations between performance-based and self-reported measures were small to medium (strength r = 0.17, mobility r = 0.45 and balance r = 0.37). The most responsive performance-based measures included walking speed (ESI 1.7, ESII 1.2), Physical Performance and Mobility Examination (ESI 1.3, ESII 1.0) and chair-rise test (ESI 1.1, ESII 0.8). Self-reported mobility (ESI 0.8, ESII 0.6) and strength (ESI 0.8, ESII 0.6) were more responsive than self-reported balance (ESI 0.3, ESII 0.2). External responsiveness (AUC) was greatest for walking speed (0.72) and lowest for the measures of body sway (0.53).

CONCLUSION

self-reported and performance-based indices appear to assess different constructs and may provide complementary information about physical functioning in people after hip fracture. Measures of strength and mobility showed greater ability to detect change than measures of balance.

Responsiveness of the EQ-5D in patients with proximal humeral fractures

BACKGROUND

This study evaluated the internal and external responsiveness of the EuroQol EQ-5D (EuroQol Group, Rotterdam, The Netherlands) health status component, defined as the instrument's ability to capture clinically important changes in patients with a proximal humeral fracture within the context of a prospective study.

MATERIALS AND METHODS

To evaluate the internal responsiveness of the EQ-5D, the observed change and the standardized response mean (SRM) in relation to the change in the EQ-5D(index) score were calculated. To calculate external responsiveness, an external criterion (EC) was constructed by using the Disabilities of the Arm, Shoulder and Hand (DASH) score. Receiver operating characteristic (ROC) curves and logistic regression analysis were used in the evaluation.

RESULTS

The mean change score from prefracture status to the 4-month follow-up for the EQ-5D was -20.9 and the corresponding SRM was 0.90, indicating good internal responsiveness. The clearly improved or clearly deteriorated patients according to the EC (DASH) reported change scores of approximately 12 points in the EQ-5D, corresponding to moderately strong SRMs, which, together with the results of the ROC analyses and logistic regression, indicated a good external responsiveness.

CONCLUSION

The EQ-5D displayed good internal and external responsiveness in patients with proximal humeral fractures and can be recommended for use as a quality of life measure in patients with this particular injury.

Proximal femoral fractures in the elderly: how are we measuring outcome?

INTRODUCTION

Patients with proximal femoral fractures present a difficult problem to health care systems in view of their complex presentations and co-morbidities. Traditionally, the focus of outcome measurement for this patient group has been on mortality and surgical implant success. Increasing recognition of the need to diversify outcome measurements has led to the creation and use of a number of outcome scales. We sought to examine how these scales are being used in the current literature.

METHODS

Abstracts to over 4000 papers related to proximal femoral fracture research were screened to identify commonly used scales in the five main categories of general quality of life measures (QoL), Activities of Daily Living scales (ADL), mobility and physical performance scales, disease-specific scales and hip-specific scales. The 14 identified scales were then searched for directly, and papers analysed for scale usage, timing and interpretation.

RESULTS

ADL scales were the most commonly used group, followed by QoL measures, which are validated for elderly patients. Scale timing and use varied widely between studies. A large number of scales were found in addition to the 14 identified scales. None of the 14 identified scales were validated for the proximal femoral fracture population.

DISCUSSION

A good scale must be appropriate in content, method and clinical utility. Its method of application must be reliable, responsive, and validated for the population in question. Outcome scale usage was difficult to assess in proximal femoral fracture research due to difficulties in isolating the relevant research, and in differences in scale timing and interpretation. Scale prevalence was skewed by use by specific research groups.

CONCLUSION

There is no single unifying scale in widespread use for proximal femoral fracture patients. We would recommend the validation of commonly used scales for this population, and would advise the use of scales from more than one category to assess outcome.

Validity and responsiveness of the Core Outcome Measures Index (COMI) for the neck

PURPOSE

Patient-orientated outcome questionnaires are essential to evaluate treatment success. To compare different treatments, hospitals, and surgeons, standardised questionnaires are required. The present study examined the validity and responsiveness of the Core Outcome Measurement Index for neck pain (COMI-neck), a short, multidimensional outcome instrument.

METHODS

Questionnaires were completed by patients with degenerative problems of the cervical spine undergoing cervical disc arthroplasty before (N = 89) and 3 months after (N = 75) surgery. The questionnaires comprised the EuroQol-Five Dimension (EQ-5D), the North American Spine Society Cervical Spine Outcome Assessment Instrument (NASS-cervical) and the COMI-neck.

RESULTS

The COMI and NASS-cervical scores displayed no notable floor or ceiling effects at any time point whereas for the EQ-5D, the highest values [corrected] were reached in around 32.5% of patients at follow-up. With one exception (symptom-specific well-being), the individual COMI items and the COMI summary score correlated to the expected extent (R = 0.4-0.8) with the scores of the chosen reference questionnaires. The area under the curve (AUC) generated by ROC analysis was significantly higher for the COMI (0.96) than for any other instrument/subscale when self reported treatment outcome was used as the external criterion, dichotomised as "good" (operation helped a lot/helped) versus "poor" (operation helped only a little/didn't help/made things worse). The COMI had a high effect size (standardised response mean; SRM) (2.34) for the good global outcome group and a low SRM for the poor outcome group (0.34). The EQ-5D and the NASS-cervical lacked this ability to differentiate between the two groups, showing less distinct SRMs for good and poor outcome groups.

CONCLUSIONS

This study provides evidence that the COMI-neck is a valid and responsive questionnaire in the population of patients examined. Further investigations should examine its applicability in other patient groups with less severe neck pain or undergoing other treatment modalities.

Musculoskeletal function and quality of life in elderly patients after a subtrochanteric femoral fracture treated with a cephalomedullary nail

OBJECTIVES

To report the musculoskeletal function and health-related quality of life in elderly patients after a subtrochanteric fracture treated with a single lag screw cephalomedullary nail.

DESIGN

Prospective cohort study with a minimum 1-year follow-up.

SETTING

University hospital.

PATIENTS

Fifty-three patients, mean age 82 years (range, 61-94 years), with a subtrochanteric fracture of the femur.

INTERVENTION

Fixation with a long Gamma cephalomedullary nail.

MAIN OUTCOME MEASUREMENTS

Reoperation rate, musculoskeletal function (Short Musculoskeletal Function Assessment), and health-related quality of life (EuroQol-5D).

RESULTS

Six patients (11%) were reoperated on, five as a result of technical failures and one as a result of an ipsilateral fracture of the distal femur. The Short Musculoskeletal Function Assessment Dysfunction Index increased from 18 before the fracture to 46 at 4 months and 43 at 12 months. The corresponding values for the Short Musculoskeletal Function Assessment Bother Index were 10 before the fracture and 43 and 40 at 4 and 12 months (P < 0.001 between follow-ups and before fracture for both indices). The EuroQol-5Dindex score decreased from 0.85 to 0.49 at 4 months and remained at almost the same level at 12 months, 0.52 (P < 0.001 between follow-ups and before fracture).

CONCLUSIONS

A subtrochanteric fracture treated with a single lag screw cephalomedullary nail had a substantial negative impact on the patient's musculoskeletal function according to the Short Musculoskeletal Function Assessment as well as on the patient's health-related quality of life. However, the need for revision surgery was comparatively low.

Internal screw fixation compared with bipolar hemiarthroplasty for treatment of displaced femoral neck fractures in elderly patients

BACKGROUND

Internal fixation and arthroplasty are the two main options for the treatment of displaced femoral neck fractures in the elderly. The optimal treatment remains controversial. Using data from the Norwegian Hip Fracture Register, we compared the results of hemiarthroplasty and internal screw fixation in displaced femoral neck fractures.

METHODS

Data from 4335 patients over seventy years of age who had internal fixation (1823 patients) or hemiarthroplasty (2512 patients) to treat a displaced femoral neck fracture were compared at a minimum follow-up interval of twelve months. One-year mortality, the number of reoperations, and patient self-assessment of pain, satisfaction, and quality of life at four and twelve months were analyzed. Subanalyses of patients with cognitive impairment and reduced walking ability were done.

RESULTS

In the arthroplasty group, only contemporary bipolar prostheses were used and uncemented prostheses with modern stems and hydroxyapatite coating accounted for 20.8% (522) of the implants. There were no differences in one-year mortality (27% in the osteosynthesis group and 25% in the arthroplasty group; p = 0.76). There were 412 reoperations (22.6%) performed in the osteosynthesis group and seventy-two (2.9%) in the hemiarthroplasty group during the follow-up period. After twelve months, the osteosynthesis group reported more pain (mean score, 29.9 compared with 19.2), higher dissatisfaction with the operation result (mean score, 38.9 compared with 25.7), and a lower quality of life (mean score, 0.51 compared with 0.60) than the arthroplasty group. All differences were significant (p < 0.001). For patients with cognitive impairment, hemiarthroplasty provided a better functional outcome (less pain, higher satisfaction with the result of the operation, and higher quality of life as measured on the EuroQol visual analog scale) at twelve months (p < 0.05).

CONCLUSIONS

Displaced femoral neck fractures in the elderly should be treated with hemiarthroplasty.

Relationship of quality of life to dispositional optimism, health locus of control and self-efficacy in older subjects living in different environments

PURPOSE

To describe the relationship of dispositional optimism, health locus of control and self-efficacy to quality of life (QOL) in older subjects differing in level of disability and institutionalisation.

METHODS

The study was conducted in the three groups of subjects aged > or = 65: 110 relatively healthy community-dwelling elderly, 102 independent elders who voluntarily decided to live in veteran home and 112 inhabitants of a long-term care home. Life orientation test-revised (LOT-R), multidimensional health locus of control (MHLC) and generalised self-efficacy scale (GSES) together with a multidimensional assessment were performed with each subject. QOL was assessed using the Euroqol 5D questionnaire, the Nottingham health profile and the satisfaction with life scale (SWLS).

RESULTS

QOL generally decreased with growing level of dependence and institutionalisation. LOT-R, MHLC and GSES were important and independent correlates of QOL in all three environments of older subjects. The relationship of education, smoking habit, physical activity, strength and mobility measures to psychological characteristics was different in the three groups of elders. LOT-R, MHLC Powerful Others, MHLC Chance and GSES were the most important QOL correlates in veteran home group, while MHLC Internal was most significant in long-term care home inhabitants.

CONCLUSIONS

Data of this cross-sectional study suggests that the veteran home elderly, as a group 'in transition' between community and institution, should be the first target of psychological preventive and health-promoting measures aimed at improving QOL in older population.

Quality of life after dislocation of hip arthroplasty: a prospective cohort study on 319 patients with femoral neck fractures with a one-year follow-up

PURPOSE

A primary arthroplasty constitutes a standard procedure in the treatment of patients with displaced fractures of the femoral neck. Although dislocation of the prosthesis remains a significant clinical problem, there are no previous reports on its influence on health-related quality of life (HRQoL). We analysed how a dislocation of the hip arthroplasty influenced the patients' HRQoL.

METHODS

In total 319 consecutive patients with a displaced fracture of the femoral neck treated with a primary arthroplasty were included in a prospective cohort study. We used a mixed-effects model regression analysis to evaluate factors of importance for HRQoL (EQ-5D(index) score) during the first 12 months following surgery.

RESULTS

A dislocation of the arthroplasty occurred in 21 of the 319 patients (7%), 8 of whom had a single dislocation and 13 recurrent dislocations. At 4 months, the EQ-5D(index) score displayed a significantly worse outcome for patients with recurrent dislocations compared to patients with no dislocation (P = 0.001), and a trend towards a worse outcome for patients with a single dislocation (P = 0.08). At 12 months, the mean EQ-5D(index) score of patients with recurrent dislocations was still substantially lower (P = 0.001), while the EQ-5D(index) score for patients with a single dislocation had returned to a level similar to that of patients with no dislocation. Our analysis of the EQ-5D dimensions indicates that the difference was mainly due to perceived difficulties in self-care and usual activities and increased problems with anxiety/depression.

CONCLUSIONS

A recurrent dislocation of the hip arthroplasty in the treatment of patients with femoral neck fractures seems to result in a persisting deterioration in the HRQoL, while patients with a single dislocation seem to experience only a temporary deterioration.

Quality of life after a subtrochanteric fracture: a prospective cohort study on 87 elderly patients

BACKGROUND

The subtrochanteric fracture constitutes approximately 5-10% of all hip fractures. This particular fracture type, owing to its configuration and instability, poses significant challenges to the fixation method, especially in elderly patients with varying degrees of osteoporosis. There has been a gradual change in the operative techniques used to stabilise these fractures leading to the current widespread use of cephalomedullary nails. In contrast to the field of research on patients with the more common femoral neck and trochanteric fractures, few studies have evaluated the health-related quality of life (HRQoL) in patients with subtrochanteric fractures.

OBJECTIVE

To report the long-term outcome for patients with subtrochanteric fractures treated with a cephalomedullary nail with special regard to the HRQoL.

SETTING

Four university hospitals.

DESIGN

A prospective cohort study with a 2-year follow-up.

PATIENTS AND METHODS

Eighty-seven consecutive elderly patients with a subtrochanteric fracture treated with a cephalomedullary nail. Main outcome measurements were mortality rate, reoperation rate, pain at the hip, walking ability, activities of daily living (ADL) function and HRQoL assessed with the EQ-5D (EQ-5D(index) score).

RESULTS

The EQ-5D(index) score decreased from 0.73 before fracture to 0.53 at 4 and 12 months and to 0.52 at 24 months. At the final follow-up 80% of the patients reported no or only limited pain at the hip, 46% had regained their prefracture walking ability, 48% their prefracture level of ADL function and 71% had living conditions similar to those before the fracture. The reoperation rate was 8%. The mortality rate was 8% at 4 months, 14% at 12 months and 25% at 24 months.

CONCLUSIONS

A subtrochanteric fracture in elderly patients had a substantial negative effect on both their short and long-term HRQoL. Although pain at the hip was not a major problem there was an obvious deterioration in walking ability and ADL function. However, the rate of revision surgery was comparatively low which confirms that the cephalomedullary nail constitutes a safe treatment for elderly patients with a subtrochanteric fracture. The data on HRQoL obtained in this study can be used in future healthcare evaluations and to calculate quality-adjusted life-years (QALYs).

Quality of life after a stable trochanteric fracture--a prospective cohort study on 148 patients

OBJECTIVE

The aim of this study was to report the long-term outcome for patients with stable trochanteric fractures, especially regarding the health-related quality of life (HRQoL).

DESIGN

A prospective cohort study with a 2-year follow-up.

SETTING

Four university hospitals.

PATIENTS

One hundred forty-eight consecutive patients with stable trochanteric fractures, that is, a 2-part fracture (J-M 1 and 2) according to the Jensen-Michaelsen classification, treated with a sliding hip screw.

MAIN OUTCOME MEASUREMENTS

Mortality rate, reoperation rate, pain at the hip, walking ability, activities of daily living (ADL) function, and HRQoL assessed with the EuroQol-5D (EQ-5D index score).

RESULTS

The 2-year mortality rate was 29%. The reoperation rate was 3%. At the final follow-up, 81% of the patients reported no or only limited pain at the hip, 55% had regained their prefracture walking ability, and 66% their prefracture level of ADL function. The EQ-5D index score decreased from 0.69 before the fracture to 0.57 at 4 months, 0.59 at 12 months, and 0.66 at 24 months.

CONCLUSIONS

Besides the expected mortality rate, the results of the study confirm a low reoperation rate and a good outcome regarding pain at the hip and only limited deterioration in HRQoL after a stable trochanteric fracture. However, a considerable number of the patients experienced deterioration in their walking ability and ADL function. The data on HRQoL obtained in this study can be used in future healthcare evaluations and to calculate quality-adjusted life years.

Personality and EQ-5D scores among individuals with chronic conditions

BACKGROUND

Personality is associated with self-rated health, but prior studies have not examined associations with preference-based measures. We hypothesized similar associations would exist with preference-based health.

METHODS

We analyzed baseline data from chronically ill individuals enrolled in a self-management intervention. We conducted regression analyses with the EQ-5D summary index score and dimension scores (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) as dependent variables, The key independent variables were NEO-Five Factor Inventory (NEO-FFI) personality factors (Neuroticism, Conscientiousness, Extraversion, Openness, Agreeableness), adjusting for age, gender, educational level, minority status, and chronic conditions.

RESULTS

Of 415 participants, 245 (59%) had > or =2 chronic conditions, 384 (94%) completed the NEO-FFI and 397 (96%) the EQ-5D. After adjustment, Neuroticism was associated with EQ-5D summary index scores [-0.04 per 1 SD increase in Neuroticism (95% CI -0.06, -0.01)]. Neuroticism [AOR 2.99 (95% CI 2.06, 4.35; P < 0.001)] and Openness [1.32 (95% CI 1.00, 1.75; P = 0.05)] were associated with worse anxiety/depression scores, while Conscientiousness was associated with better usual activities scores [0.66 (95% CI 0.49, 0.89; P = 0.01)].

CONCLUSIONS

The associations between personality factors and self-rated health appear to extend to preference-based measures. Future studies should explore whether personality affects preference-based health estimates in cost-effectiveness analyses.

Outcome after femoral neck fractures: a comparison of Harris Hip Score, Eq-5d and Barthel Index

INTRODUCTION

The objective of this study was to evaluate the discriminatory ability and responsiveness of the Harris Hips Score, the Barthel Index and the Eq-5d (Euroqol) in an unselected population of patients with displaced femoral neck fracture.

METHODS

Data were collected at 4 and 12 months after surgery from a population of 222 patients. Patients with complete data sets who suffered a serious complication (n=23) were compared with patients with no complication (n=56). The assessment scales' ability to discriminate between the groups was calculated, as was the change score and the standardised response mean.

RESULTS

All scales were able to discriminate between the complications group and the non-complications group at 4 months, but only Harris Hip Score had independent explanatory ability in a logistic regression analysis. All scales showed a positive change score for the complications group from 4 to 12 months. The standardised response mean was 0.75 for Harris Hip Score, 0.40 for Barthel Index, 0.46 for the Eq-5d index score, and 0.57 for the Eq-5d visual analogue scale. Barthel Index had a marked ceiling effect with 51/79 (65%) scoring 19 or 20 at 4 months. The response rate was 71-87% for Eq-5d and 96-98% for Harris Hip Score and Barthel Index.

CONCLUSION

All the scales may be used for this patient group, but Harris Hip Score performed better than the other scales.

Hemiarthroplasty or internal fixation for intracapsular displaced femoral neck fractures: randomised controlled trial

OBJECTIVE

To compare the functional results after displaced fractures of the femoral neck treated with internal fixation or hemiarthroplasty.

DESIGN

Randomised trial with blinding of assessments of functional results.

SETTING

University hospital.

PARTICIPANTS

222 patients; 165 (74%) women, mean age 83 years. Inclusion criteria were age above 60, ability to walk before the fracture, and no major hip pathology, regardless of cognitive function.

INTERVENTIONS

Closed reduction and two parallel screws (112 patients) and bipolar cemented hemiarthroplasty (110 patients). Follow-up at 4, 12, and 24 months.

MAIN OUTCOME MEASURES

Hip function (Harris hip score), health related quality of life (Eq-5d), activities of daily living (Barthel index). In all cases high scores indicate better function.

RESULTS

Mean Harris hip score in the hemiarthroplasty group was 8.2 points higher (95% confidence interval 2.8 to 13.5 points, P=0.003) at four months and 6.7 points (1.5 to 11.9 points, P=0.01) higher at 12 months. Mean Eq-5d index score at 24 months was 0.13 higher in the hemiarthroplasty group (0.01 to 0.25, P=0.03). The Eq-5d visual analogue scale was 8.7 points higher in the hemiarthroplasty group after 4 months (1.9 to 15.6, P=0.01). After 12 and 24 months the percentage scoring 95 or 100 on the Barthel index was higher in the hemiarthroplasty group (relative risk 0.67, 0.47 to 0.95, P=0.02. and 0.63, 0.42 to 0.94, P=0.02, respectively). Complications occurred in 56 (50%) patients in the internal fixation group and 16 (15%) in the hemiarthroplasty group (3.44, 2.11 to 5.60, P<0.001). In each group 39 patients (35%) died within 24 months (0.98, 0.69 to 1.40, P=0.92)

CONCLUSIONS

Hemiarthroplasty is associated with better functional outcome than internal fixation in treatment of displaced fractures of the femoral neck in elderly patients.
