The Impact of Delirium on Recovery in Geriatric Rehabilitation after Acute Infection

OBJECTIVES

Delirium is common during acute infection in older patients and is associated with functional decline. Geriatric rehabilitation (GR) can help older patients to return to their premorbid functional level. It is unknown whether delirium affects GR outcomes in patients with acute infection. We evaluated whether delirium affects trajectories of activities of daily living (ADL) and quality of life (QoL) recovery in GR after COVID-19 infection.

DESIGN

This study was part of the EU-COGER study, a multicenter cohort study conducted between October 2020 and October 2021.

SETTING AND PARTICIPANTS

Participants were recruited after COVID-19 infection from 59 GR centers in 10 European countries.

METHODS

Data were collected at GR admission, discharge, and at the 6-week and 6-month follow-ups. Trajectories of ADL [using the Barthel index (BI)] and QoL [using the EuroQol-5 Dimensions-5 Level (EQ-5D-5L)] recovery were examined using linear mixed models.

RESULTS

Of the 723 patients included (mean age 75.5 ± 9.9 years; 52.4% male), 28.9% had delirium before or during GR admission. Participants with delirium recovered in ADL at approximately the same rate as those without (linear slope effect = -0.13, SE 0.16, P = .427) up to an estimated BI score of 16.1 at 6 months. Similarly, participants with delirium recovered in QoL at approximately the same rate as those without (linear slope effect = -0.017, SE 0.015, P = .248), up to an estimated EQ-5D-5L score of 0.8 at 6 months.

CONCLUSIONS AND IMPLICATIONS

Presence of delirium during the acute phase of infection or subsequent GR did not influence the recovery trajectory of ADL functioning and QoL.

348 WHAT IS THE OLDER PATIENT’S VIEW ON RECEIVING DETAILED MEDICAL LETTERS?

Background

Sending copies of clinic letters to patients involves additional work for medical staff in formatting letters, administrative staff in printing and posting and is an added cost to the healthcare service. Though seen largely as good practice in some specialities, it is not done routinely in Geriatric medical services. We introduced this practice as standard in our service and wished to evaluate whether from the patient perspective, it is worthwhile.

Methods

We sent a questionnaire to n=80 older patients who were evaluated in the home setting (by the Integrated Care Team for Older People – ICTOP) or recently attended CGA (Comprehensive Geriatric Assessment) clinic or FLS (Fracture Liaison Service) clinic. We asked their opinion on the detailed medical letter sent to their General Practitioner (GP), which they received a copy of. The questionnaire could be completed by patient/carer/relative, and returned anonymously.

Results

N=30/80 were returned. Two said they found the letter difficult to understand; 1/30 said the letter caused them to worry but all said they still preferred that they had received it. N= 2 said they would like to have contributed to the letter for accuracy. All said they felt they should receive copies of all their medical correspondence. Free text comments showed overwhelming support for the process, in allowing them to self-manage their health, enhance communication with other healthcare professionals and was a useful document to refer back to when they are trying to process information during short consultations.

Conclusion

Though a small survey and limited by low response rate, older people expressed high levels of satisfaction in receiving copies of medical letters about their health. It supports the ongoing practice and should be adopted widely.

253 DELIRIUM IDENTIFICATION AT INITIAL TRIAGE IN AN IRISH EMERGENCY DEPARTMENT SETTING

Background

Over 10% of older adults are affected by delirium on presentation to Emergency Departments (ED), with many more developing it during a prolonged ED stay. Early detection is key to delirium management, but the diagnosis is often missed, with over 50% of delirium going undetected in the ED. In 2019 the HSE guideline on Early Identification and Management of Delirium in the ED recommended that all those over 65 years be screened on presentation to ED using the 4AT, a validated instrument in delirium screening. Through our ED’s delirium working group, we conducted a baseline audit on current rates of screening for delirium, ahead of a quality improvement project on management of patients with, or at risk of delirium in our ED.

Methods

A retrospective review was conducted of consecutive patients >65yrs who presented to ED in one month with the following terms mentioned in the presenting complaint at triage: confusion/delirium/memory/speech/language disturbance/agitation i.e. terms that could indicate possible delirium as considered by the triage practitioner. We also recorded whether a 4AT was recorded. An additional 50 charts from the consecutive series were randomly selected and examined for probable delirium on presentation which was not captured at triage.

Results

n=23/1,597 (<1%) had possible delirium recorded at triage as per our criteria. In-depth case note review supported the diagnosis of delirium in 20 of the 23 initially identified at triage. Only 5 of these had a documented 4AT score. Of the additional 50 charts screened, a further 6 had likely delirium of whom n=3 had a 4AT score completed. N=16 required hospital admission.

Conclusion

Delirium screening and detection rates at ED triage are less than expected, and below the 2019 national screening recommendations. Implementing same in any busy ED is challenging. We are developing a multifaceted educational program to address this and plan a repeat audit following implementation.

300 ESTABLISHING THE PREVALENCE OF OSTEOPOROTIC FRACTURES IN IRELAND

Background

Fragility/low-trauma fractures are a major burden on health care, yet many could be prevented through Fracture Liaison Services (FLS). An Irish national FLS database (FLSDB) has recently been established and a reliable estimate of fracture numbers per locality is needed to measure FLS efficiency. Currently the Irish FLSDB uses the UK estimate of 1:4 hip vs. non-hip fracture numbers. We wanted to explore its accuracy in an Irish population.

Methods

We looked at all plain x-ray reports from six individual weeks across two years in our hospital. We selected those aged >50yrs with a reported new fracture. We determined the ratio of hip:non-hip fractures and of those admitted vs. discharged. We cross checked these against admitted fracture numbers from NQAIS (National Quality Assurance Information System) for the same 6 weeks. We then looked at all admissions Irish Emergency Departments during 2018-2019 with a new fracture aged >50yrs. We compared hip:non-hip fracture ratio of these vs. our local data.

Results

From 7,654 x-ray reports, 222 new fracture patients were identified. An additional 29 patients sustained fractures during this time period, either CT/MRI diagnoses or managed as fractures despite negative radiology report. NQAIS missed 21 admitted fractures (uncoded). The ratio admitted:discharged fractures in our audit was 2:3. Ratio of patients with hip:non-hip fractures was 1:9.5. Nationally there were 33,627 fracture patients aged >50y admitted to Irish hospitals in 2018-9, and of these, the hip:non-hip fracture ratio was 1:3. Adding estimated numbers of fracture patients not admitted (based on our local data) gives at least a 1:9 hip:non-hip ratio nationally.

Conclusion

Fracture numbers in Ireland are markedly underestimated if extrapolating from UK estimates. This has implications for service planning for Irish FLS, if rising fracture numbers are to be addressed.

Fracture liaison services in Ireland-how do we compare to international standards?

In this first na tional survey of public hospitals in The Republic of Ireland, we found fracture liaison services (FLS) to be heterogeneous, limited in many cases and poorly supported. A national strategy is urgently needed to support the implementation and operation of an FLS, and thus help reduce the burden of fragility fractures for patients and the healthcare system.

INTRODUCTION

Fragility/low-trauma fractures are a global concern, whose incidence is rising as the population ages. Many are preventable, and people with a prior fragility fracture are at particularly high risk of further fractures. This patient group is the target of the International Osteoporosis Foundation (IOF) Capture the Fracture campaign, advocating global adoption of fracture liaison services (FLS), with the aim of preventing secondary fragility fractures. We wished to determine the current availability and standards of an FLS in Ireland, ahead of the launch of a National FLS database.

METHODS

We devised a questionnaire encompassing the thirteen IOF standards for an FLS and asked all 16 public hospitals with an orthopaedic trauma unit in Ireland, to complete for the calendar year 2019 in patients aged ≥ 50 years.

RESULTS

All sites returned the questionnaire, i.e. 100% response rate. Nine hospitals stated that they have an FLS, additionally one non-trauma hospital running a FLS responded, and were included. These 10 FLS had identified and managed 3444 non-hip fractures in the year 2019. This figure represents 19% of the expected non-hip fragility fracture numbers occurring annually in Ireland. Implementation of the IOF standards was very variable. All sites reported being inadequately resourced to provide a high-quality service necessary to be effective.

CONCLUSION

The existence and functioning of FLS in Ireland are heterogeneous and suboptimal. A national policy to support the implementation of this programme in line with international standards of patient care is urgently needed.

114 FALLS AND SYNCOPE GUIDELINES APPLIED TO EMERGENCY DEPARTMENT ATTENDEES—HOW DO WE PERFORM?

Background

Falls and syncope are one of the most common presentations to emergency departments amongst older people. European Society of Cardiology (ESC) guidelines describe investigation of suspected syncope to assist care.

Methods

Following a previous audit we delivered an education program to Emergency Department (ED) staff, on assessment of fallers and syncope. This was a repeat cycle audit on consecutive patients aged who presented with a fall/faint/collapse/blackout/syncope, to assess impact of education sessions. We also conducted a survey of n = 23 ED staff members, on role of orthostatic blood pressures and ECGs in falls assessments.

Results

Of 80 consecutive attendees with a fall, n = 41 (51%) had possible syncope as documented in the history. ECG was done within the ED in 88% vs. 51% on baseline audit however only 14% (11/80) had lying and standing blood pressure checked vs. 15% on baseline audit. This is despite our survey showing that 17/23 (74%) of ED staff felt that orthostatic BP checks were essential in all fallers, and 44% stating they measure it themselves. Brain imaging was conducted in 44% vs. 40% in baseline audit, rationale for which was unclear in some. 31% (n = 25) were admitted compared to 42% previously. Of the n = 23 admitted, 24% (n = 6) had telemetry or Holter monitor, 20% had an echocardiogram.

Conclusion

Despite an education program on assessment of older fallers, embedding it to alter practice is challenging. While the education program resulted in some improvements, it supports a dedicated team for assessing fallers in the ED. Given the low rate of further investigations into causes for those admitted, a rapid access out patient pathway is warranted. Brain imaging is carried out relatively frequently though we cannot conclude on appropriateness in this limited audit.

Prevalence of vitamin K deficiency in older people with hip fracture

Introduction: Vitamin K plays an important role in blood coagulation. Diet is the main source of vitamin K and body stores are depleted in days, hence deficiency is common in malnourished older people. A high proportion of people who sustain a hip fracture are already malnourished, compounded by fasting for surgery which might further increase deficiency. We wanted to explore the prevalence of vitamin K deficiency in hip fracture patients and the impact of a short period of fasting.Methods: In consecutive patients hospitalised with a hip fracture, we measured vitamin K and PIVKA-II (undercarboxylated factor II - a marker of subclinical vitamin K status) on admission and on first post-operative day. We excluded those on anticoagulants.Results: N = 62 participated; 4 had missing pre-op vitamin K samples and n = 3 had no surgery leaving n = 55 with paired samples. Mean age was 80.0 ± 9.6 years, 33% males. Prevalence of subclinical vitamin K deficiency on admission was 36% (20/55) based on reference range of > 0.15µg/L. The proportion with subclinical K deficiency after surgery rose to 64% (35/55), p < 0.05. 13% had detectable PIVKA-II concentrations pre-operatively, 15% did post-operatively. None had abnormal prothrombin time. Vitamin K status was not associated with post-operative haemoglobin drop or transfusion requirements.Conclusion: Prevalence of vitamin K deficiency in hip fracture patients is high and increases further following a short period of fasting. Though no significant impact was noted on peri-operative blood loss, larger studies are warranted to explore this, and the potential role of vitamin K supplements peri-operatively.

Takayasu's arteritis: a cause of prolonged arterial stiffness

OBJECTIVES

Cardiovascular disease is a major cause of mortality and morbidity in patients with Takayasu's arteritis (TA). Increased arterial stiffness is an independent risk factor and predictor of cardiovascular mortality in a variety of diseases. Pulse wave velocity (PWV) and the augmentation index (AI) are used as clinical measurements of arterial stiffness.

METHODS

Data are presented from 10 patients with TA and 11 normal controls obtained between 2000 and 2004. Arterial compliance was assessed non-invasively by measurement of PWV, using the Complior system, and calculation of the aortic AI.

RESULTS

TA patients (mean age 40.8+/-13.2 yr) were compared with a control group of healthy women from a parallel study (mean age 32.3+/-5.5 yr). The mean carotid-femoral PWV (PWV-CF) was higher in TA patients (P = 0.03). In addition, both aortic AI derived from the radial artery (P = 0.002) and carotid AI (P = 0.03) were higher in TA patients compared with controls. PWV-CF did not correlate with CRP (r = - 0.23, P = 0.23) or ESR (r = - 0.19, P = 0.27). Similar results were obtained for the correlation of carotid-radial PWV with CRP (r = 0.15, P = 0.32) and ESR (r = 0.33, P = 0.14).

CONCLUSIONS

Our data show that TA is associated with elevated arterial stiffness in the central aorta, which may persist when the disease is quiescent. These data suggest that PWV represents a means by which cardiovascular risk can be detected and monitored in TA, and highlights the importance of effective management of cardiovascular risk factors in these patients.

Testosterone suppression in men with prostate cancer is associated with increased arterial stiffness

Low androgen levels in men are associated with increased cardiovascular risk, through unclear mechanisms. We measured arterial stiffness ('compliance') in 21 men receiving complete testosterone suppression therapy for prostate cancer, and in 25 controls. Systemic arterial compliance (SAC), which assesses proximal aortic stiffness, was calculated by simultaneous recording of aortic flow and carotid artery pressure (the 'area method'). Aorto-femoral (A-F), aorto-radial (A-R) and femoral-dorsalis pedis (F-DP) pulse-wave velocities (PWVs) were recorded using the 'Complior' system. SAC was significantly lower in the androgen-depleted men compared to controls (0.81 +/- 0.53 vs. 1.18 +/- 0.43 arbitrary compliance units, p = 0.01, mean +/- SD). Correspondingly, their A-F PWV was higher (14.1 (10.1-21.8) vs. 12.4 (9.6-17.4) m/s, p = 0.03, median (range)). Cases tended to be older (75 +/- 7 vs. 71 +/- 6 years, p = 0.07), and to have higher systolic blood pressure (148 +/- 22 vs. 143 +/- 17 mmHg, p = 0.40); however, SAC was still significantly lower (p = 0.03) after adjustment for age and stratification for central systolic pressure (< or = or > the median). Adjustment of A-F PWV for age and central systolic pressure reduced significance to p = 0.07. There was no significant difference in peripheral PWVs between groups. In conclusion, testosterone suppression is associated with increased aortic stiffness, only partly explained by age and blood pressure. Loss of androgens in men might therefore adversely affect cardiovascular risk.

The effect of reminder calls in reducing non-attendance rates at care of the elderly clinics

BACKGROUND

DNA ("did not attend") at outpatient clinics is an important problem costing the NHS an estimated pound266 million annually. The national DNA rate for 1996-1997 for all clinics was 12%. The DNA rate at Hammersmith Hospital for the same year in the care of the elderly specialty was 21%. The aim of this study was to establish why this was so, and to test the efficacy of a reminder call in increasing attendance rates at care of the elderly clinics.

METHODS

23 DNAs from seven clinics were contacted to ascertain the reasons for non-attendance (group I). For seven further clinics, 84 patients were contacted in advance to reconfirm their appointment (group II).

RESULTS

From group II 12 patients were identified who were unaware of their appointment (14%), six of whom agreed to attend; thus six potential DNAs were prevented. Eleven vacant appointments were identified in advance. The unexpected DNA rate was reduced to 5% from a potential 21% as a result of this exercise. The DNA rate for all patients with dementia (both groups) was 44%, whereas the DNA rate for all patients without this diagnosis (both groups) was 16% (p < 0.001).

CONCLUSIONS

A preclinic phone call reminder to elderly patients is feasible, increases attendance rates, and identifies vacant appointments. Patients with dementia are more likely to miss clinic appointments; therefore they and their carers need specific reminders about appointment dates.

Androgen deprivation in males is associated with decreased central arterial compliance and reduced central systolic blood pressure

The higher incidence of coronary artery disease in men is often attributed to androgens. Arterial compliance or 'stiffness' is increasingly regarded as a modifiable risk factor for cardiovascular disease. We wanted to look at the effects of complete androgen withdrawal, on arterial compliance in men. We performed arterial compliance studies on 12 men with complete androgen deprivation as treatment for prostate cancer, and on 12 age-matched healthy controls. Central pulse wave velocities were significantly higher in the androgen-deprived men (14.2 +/- 2.7 vs 11.8 +/- 1.6 m/sec, P = 0. 02). The cases tended to have higher brachial systolic pressures than controls though this difference was not significant (P = 0.2). We conclude that androgen withdrawal is associated with a reduction in central arterial compliance. Conversely androgen withdrawal does not affect peripheral arterial compliance. It is unlikely that the presence of normal concentrations of androgens can explain the sex difference in mortality rates. Longitudinal studies are needed for further evaluation.
