Postoperative adverse outcomes in surgical patients with dementia: a retrospective cohort study. World J Surg. 2012;36:2051-2058. [PMID: 22535212 DOI: 10.1007/s00268-012-1609-x]

Dementia is associated with worse procedural outcomes after mitral valve transcatheter edge-to-edge repair

BACKGROUND

Patients with dementia are at increased risk for adverse events following valvular surgery. Outcomes after mitral transcatheter edge-to-edge repair (TEER) for mitral regurgitation in this vulnerable population are not well understood.

METHODS

We queried the National Inpatient Sample database for all hospitalizations for mitral TEER between 2016 and 2019. Patients with a validated diagnosis code for dementia were identified by ICD-10 codes and compared to a matched cohort of non-dementia patients using multivariable regression analysis. The primary outcome was in-hospital mortality. Secondary outcomes were hospital length of stay, discharge to nursing facility, total hospital charges, and in-hospital adverse events.

RESULTS

24,550 hospitalizations for mitral TEER were identified, including 880 patients (3.6 %) with dementia. Dementia was associated with higher in-hospital mortality (OR 4.31, 95 % CI 2.65 to 6.99, p < 0.001), prolonged length of hospital stay (OR 1.33, 95 % CI 1.12 to 1.57, p 0.001), higher discharge rate to nursing facility (OR 2.71, 95 % CI 2.13-3.44, p < 0.001), and higher rate of in-hospital adverse events including delirium (OR 5.88, 95 % CI 4.06 to 8.52, p < 0.001) and acute stroke (OR 8.87, 95 % CI 5.01 to 15.70, p < 0.001).

CONCLUSIONS

Dementia is associated with worse post-procedural outcomes after mitral TEER. Further investigation is needed to elucidate mechanisms of poor clinical outcomes and guide shared decision-making in this vulnerable population.

Impact of Dementia on the Postoperative Outcomes in Patients Undergoing Surgery for Head and Neck Cancers: A National Study

BACKGROUND

Dementia, a growing concern among the elderly, has an increased poor postoperative outcome that goes unrecognized by many. Our study aims to establish if dementia plays a role in the outcomes of head and neck cancer patients that undergo resections.

METHODS

We queried the National Inpatient Sample (NIS) database from 2016 to 2019 with a primary diagnosis of head and neck cancer who underwent surgical resection. Outcomes analyzed include postoperative delirium, ICU stay, complications, length of stay, and non-routine discharge.

RESULTS

A total of 77095 patients were included, of which 1140 patients had dementia. The mean age of the patients with dementia was 77.5 years (±9.1) versus 63.2 years (±12.1) with no dementia. Dementia patients had a higher non-home discharge rate (77.2% vs 46.8%, p = <0.001), extended length of stay (10.9 days ±14.7 vs 7.9 days ±8.8), postoperative delirium (15.4% vs 1.5%, p = <0.001), and longer ICU stay (8.3% vs 5.8%) as compared with patients with no dementia. A higher number of patients with Dementia were placed in long-term facilities (53.5% vs 14.6%) postoperatively. More dementia patients (7.9% vs 0.9%) were transferred in from another health care facility for surgery. Dementia was associated with higher odds of delirium (OR, 6.36; 95% CI, 5.2-7.77), non-routine discharge (OR, 2.05; 95% CI, 1.76-2.3), ventilation (OR, 0.8; 95% CI, 0.6-1.05), and length of stay (estimate 3.01, 95% CI, 1.84-4.184).

CONCLUSION

Preoperative dementia significantly impacts postoperative delirium, non-home discharge, and extended length of stay in head and neck cancer patients undergoing surgery.

Mortality Among the Dementia Population in Not-For-Profit Hospitals with Better Nursing Resources

The dementia population has higher rates of mortality during hospital stays than those without dementia. The aim of this study is to examine the relationship between ownership status (i.e. for-profit vs. not-for-profit) and nursing resources (i.e. nurse work environment, nurse-to-patient staffing, and nurse education) on 30-day mortality among post-surgical older adults with dementia. A cross-sectional analysis of linked American Hospital Association, Medicare claims, and nurse survey data was conducted using multi-level logistic regression models. We examined these models to assess the relationship between ownership status and 30-day mortality after adjusting patient and hospital characteristics. We also analyzed the relationship between the hospital ownership status and the 30-day mortality, after considering the three nursing resources. Older adults with dementia who received care in hospitals with not-for-profit status were less likely to die within 30 days of admission following surgery compared to those treated in hospitals with for-profit hospital status (i.e. odds ratio 0.82, 95% confidence interval 0.73-0.92, p = <.001). In addition, the odds ratios estimating the association between ownership and mortality were similar across the different models of the three nursing resources with and without those controls (i.e. 0.88 vs. 0.83 vs. 0.82). Surgical patients with dementia had better outcomes when cared for in not-for-profit hospitals, particularly with greater levels of nurse education and nurse staffing. The relationship between profit status and mortality was partly explained by the lower levels of nurse staffing and education in for-profit vs. not-for-profit hospitals.

Total shoulder arthroplasty in patients with dementia or mild cognitive impairment

Background

Anatomic total shoulder arthroplasty (ATSA) and reverse total shoulder arthroplasty (RTSA) reliably alleviate pain and restore shoulder function for a variety of indications. However, these procedures are not well-studied in patients with neurocognitive impairment. Therefore, the purpose of this study was to investigate whether patients with dementia or mild cognitive impairment (MCI) have increased odds of surgical or medical complications following arthroplasty.

Methods

The PearlDiver database was queried from 2010 through October 2021 to identify a cohort of patients who underwent either ATSA or RTSA and had a minimum 2-year follow-up. Current Procedural Terminology and International Classification of Diseases codes were used to stratify this cohort into three groups: (1) patients with dementia, (2) patients with MCI, and (3) patients with neither condition. Surgical and medical complication rates were compared among these three groups.

Results

The overall prevalence of neurocognitive impairment among patients undergoing total shoulder arthroplasty was 3.0% in a cohort of 92,022 patients. Patients with dementia had increased odds of sustaining a periprosthetic humerus fracture (odds ratio [OR] = 1.46, P < .001), developing prosthesis instability (OR = 1.72, P < .001), and undergoing revision arthroplasty (OR = 1.55, P = .003) after RTSA compared to patients with normal cognition. ATSA patients with dementia did not have an elevated risk of surgical complications or revision. Conversely, RTSA patients with MCI did not have an elevated risk of complications or revision, although ATSA patients with MCI had greater odds of prosthesis instability (OR = 2.51, P = .008). Additionally, patients with neurocognitive impairment had elevated odds of medical complications compared to patients with normal cognition, including acute myocardial infarction and cerebrovascular accident.

Conclusion

Compared to patients with normal cognition, RTSA patients with preoperative dementia and ATSA patients with preoperative MCI are at increased risk for surgical complications. Moreover, both ATSA and RTSA patients with either preoperative MCI or dementia are at increased risk for medical complications. As the mean age in the U.S. continues to rise, special attention should be directed towards patients with neurocognitive impairment to minimize postoperative complications aftertotal shoulder arthroplasty, and the risks of this surgery more carefully discussed with patients and their families and caretakers.

Association of neurocognitive disorders with morbidity and mortality in older adults undergoing major surgery in the USA: a retrospective, population-based, cohort study

BACKGROUND

Neurocognitive disorders become increasingly common as patients age, and increasing numbers of surgical interventions are done on older patients. The aim of this study was to understand the clinical characteristics and outcomes of surgical patients with neurocognitive disorders in the USA in order to guide future targeted interventions for better care.

METHODS

This retrospective cohort study used claims data for US Medicare beneficiaries aged 65 years and older with a record of inpatient admission for a major diagnostic or therapeutic surgical procedure between Jan 1, 2017, and Dec 31, 2018. Data were retrieved through a data use agreement between Dartmouth Hitchcock Medical Center and US Centers for Medicare and Medicaid Services via the Research Data Assistance Center. The exposure of interest was the presence of a pre-existing neurocognitive disorder as defined by diagnostic code within 3 years of index hospital admission. The primary outcome was mortality at 30 days, 90 days, and 365 days from date of surgery among all patients with available data.

FINDINGS

Among 5 263 264 Medicare patients who underwent a major surgical procedure, 767 830 (14·59%) had a pre-existing neurocognitive disorder and 4 495 434 (85·41%) had no pre-existing neurocognitive disorder. Adjusting for demographic factors and comorbidities, patients with a neurocognitive disorder had higher 30-day (hazard ratio 1·24 [95% CI 1·23-1·25]; p<0·0001), 90-day (1·25 [1·24-1·26]; p<0·0001), and 365-day mortality (1·25 [1·25-1·26]; p<0·0001) compared with patients without a neurocognitive disorder.

INTERPRETATION

Our findings suggest that the presence of a neurocognitive disorder is independently associated with an increased risk of mortality. Identification of a neurocognitive disorder before surgery can help clinicians to better disclose risks and plan for patient care after hospital discharge.

Impact of Dementia on Incidence and Severity of Postoperative Pulmonary Complications Following Hip Fracture Surgery Among Older Patients

Postoperative pulmonary complications (PPCs) are the leading cause of death following hip fracture surgery. Dementia has been identified as a PPC risk factor that complicates the clinical course. By leveraging electronic health records, this retrospective observational study evaluated the impact of dementia on the incidence and severity of PPCs, hospital length of stay, and postoperative 30-day mortality among 875 older patients (≥65 years) who underwent hip fracture surgery between October 1, 2015 and December 31, 2018 at a health system in the southeastern United States. Inverse probability of treatment weighting using propensity scores was utilized to balance confounders between patients with and without dementia to isolate the impact of dementia on PPCs. Regression analyses revealed that dementia did not have a statistically significant impact on the incidence and severity of PPCs or postoperative 30-day mortality. However, dementia significantly extended the hospital length of stay by an average of 1.37 days.

Electronic Health Record Usability and Postsurgical Outcomes Among Older Adults With Dementia

INTRODUCTION

Electronic health record (EHR) usability, defined as the extent to which the system can be used to complete tasks, can influence patient outcomes. The aim of this study is to assess the relationship between EHR usability and postsurgical outcomes of older adults with dementia including 30-day readmission, 30-day mortality, and length of stay (LOS).

METHODS

A cross-sectional analysis of linked American Hospital Association, Medicare claims data, and nurse survey data was conducted using logistic regression and negative binominal models.

RESULTS

The dementia population who received care in hospitals with better EHR usability were less likely to die within 30 days of their admission following surgery compared to hospitals with poorer EHR usability (OR: 0.79, 95% CI: 0.68-0.91, p = 0.001). EHR usability was not associated with readmission or LOS.

DISCUSSION

Better nurse reported EHR usability has the potential to reduce mortality rates among older adults with dementia in hospitals.

A narrative review of staff views about dementia care in hospital through the lens of a systems framework

Background

Significant numbers of people with dementia are admitted into acute settings. They are likely to face poor health outcomes during hospitalisation. There is the need to fully understand the care provided to people with dementia through novel methods such as a systems approach (i.e. human interactions, policy, environment and equipment).

Aim

The aim of this literature review is to explore hospital practitioners' views on dementia care and to analyse findings using a systems approach.

Methods

We conducted a narrative review of primary studies that examined dementia care in acute settings. We analysed a total of 33 papers using Thomas and Harden's thematic synthesis guidelines.

Results

Thirty-three papers met the inclusion criteria for the review. The findings were as follows: (1) staff-patient relationships (e.g. coping with difficult behaviour), (2) staff-family relationships (e.g. the benefits of involving families in patient care), (3) staff-staff relationships (e.g. building a robust multidisciplinary team), (4) staff-patient care decisions (e.g. decisions directly related to the patient), (5) the environment (e.g. difficulty in adjusting to the hospital environment), (6) policies (e.g. hospital bureaucratic processes) and (7) equipment (e.g. pain assessment tools).

Conclusion

The paper revealed multidimensional challenges in the provision of dementia care within hospitals. We conclude that training programmes, hospital policies and processes aimed at improving outcomes for patients with dementia should adopt a systems approach which focuses on the relational, environmental, procedural and instrumental aspects of the hospital system.

Item distribution, scalability and internal consistency of the QUALIDEM quality of life assessment for patients with dementia in acute hospital settings

BACKGROUND

Quality of life (QoL) of people with dementia (PwD) is an important indicator of quality of care. Studying the impact of acute hospital settings on PwD's QoL requires assessment instruments that consider environmental factors. Until now, dementia-specific QoL instruments have not yet demonstrated their feasibility in acute hospitals because their use takes up too much time or their validity depends on observation periods that usually exceed the average length of hospital stays. Therefore, validated instruments to study QoL-outcomes of patients with dementia in hospitals are needed.

METHODS

Data stem from a study that analyzed the impact of a special care concept on the QoL of patients with dementia in acute hospitals. Total sample size consisted of N = 526 patients. Study nurses were trained in using an assessment questionnaire and conducted the data collection from June 2016 to July 2017. QoL was assessed with the QUALIDEM. This instrument consists of nine subscales that can be applied to people with mild to severe dementia (N = 344), while six of the nine subscales are applicable for people with very severe dementia (N = 182). Scalability and internal consistency were tested with Mokken scale analysis.

RESULTS

For people with mild to severe dementia, seven out of nine subscales were scalable (0.31 ≤ H ≤ 0.75). Five of these seven subscales were also internally consistent (ρ ≥ 0.69), while two had insufficient reliability scores (ρ = 0.53 and 0.52). The remaining two (positive self-image, feeling at home) subscales had rather low scalability (H = 0.17/0.16) and reliability scores (ρ = 0.35/0.36). For people with very severe dementia, all six subscales were scalable (0.34 ≤ H ≤ 0.71). Five out of six showed acceptable internal consistency (ρ = 0.65-0.91). Only the item social relations had insufficient reliability (ρ = 0.55).

CONCLUSIONS

In comparison with a previous evaluation of the QUALIDEM in a long-term care setting, the application in a hospital setting leads to very similar, acceptable results for people with mild to severe dementia. For people with very severe dementia, the QUALIDEM seems to fit even better in a hospital context. Results suggest either a revision of unsatisfactory items or a general reduction to six items for the QUALIDEM, for all PwD. In general, the QUALIDEM can be recommended as instrument to assess the QoL for PwD in the context of hospital research. Additionally, an investigation of the inter-rater reliability is necessary because the qualification of the nurses and the length of stay of the patients in the hospital differ from the previous investigations of the inter-rater reliability of QUALIDEM in the nursing home.

Trends and Outcomes in Patients with Dementia Undergoing Spine Fusions: A Matched Nationwide Inpatient Sample Analysis

BACKGROUND

The aim of our study was to define the trends and outcomes in patients with a preexisting diagnosis of dementia who underwent spine fusions using a large national database.

METHODS

The Nationwide Inpatient Sample database was queried using the International Classification of Diseases, Ninth Revision and Tenth Revision, from 1998 to 2018. We included patients who underwent spine fusions with or without the diagnosis of dementia. Outcomes were trends, complications, length of stay (LOS), discharge disposition, and mortality.

RESULTS

A cohort of 4495 patients (N = 1,390,657; 0.32%) with dementia who underwent spine fusions was identified. There was an increasing trend of spine fusions in patients with the diagnosis of dementia. Most patients with dementia were white (77% vs. 69%), with ≥3 comorbidities (70% vs. 23%), had Medicare insurance (83% vs. 34%) compared with patients without dementia (P < 0.0001). Overall, 38% of patients had complications after spine fusions compared with 21% of patients without dementia during the study period. Median LOS was significantly longer in patients with dementia compared with patients without dementia (6 vs. 4 days). Patients with dementia were less likely to be discharged home (19% vs. 40%) and incurred higher in-hospitalization charges ($139,101 vs. $101,629) compared with patients without dementia. No differences in terms of in-hospital mortality were noted across the cohorts (1.4% vs. 1.6%).

CONCLUSIONS

Patients with dementia had 1.5 times longer LOS and 1.4 times higher index hospitalization charges and were 2.5 times more likely to have complications and 71% less likely to be discharged home, with no difference in mortality compared with patients without dementia after spine fusions.

Two factors that can increase the length of hospital stay of patients with dementia

OBJECTIVES

Patients with dementia are at greater risk of a long hospital stay and this is associated with adverse outcomes. The aim of this service evaluation was to identify variables most predictive of increased length of hospital stay amongst patients with dementia.

METHODS/DESIGN

We conducted a retrospective analysis on a cross-sectional hospital dataset for the period January-December 2016. Excluding length of stay less than 24h and readmissions, the sample comprised of 1133 patients who had a dementia diagnosis on record.

RESULTS

The highest incidence rate ratio for length of stay in the dementia sample was: (a) discharge to a care home (IRR: 2.443, 95% CI 1.778-3.357), (b) falls without harm (IRR: 2.486, 95% CI 2.029-3.045).

CONCLUSIONS

Based on this dataset, we conclude that improvements made to falls prevention strategies in hospitals and discharge planning procedures can help to reduce the length of stay for patients with dementia.

The significance of comorbidity burden among older patients undergoing abdominal emergency or elective surgery

BACKGROUND

Comorbidities may cause complications in perioperative care and affect treatment outcomes of older patients. The study aim was to analyse comorbidity burdens with respect to their predictive power in outcome prediction in elderly qualified for abdominal elective or emergency surgery.

METHODS

Consecutive patients undergoing major abdominal surgery between 2010 and 2017 at a secondary referral hospital were included in the retrospective study, for a total of 1586 patients. To explain the relationship between the comorbidity types and 30-day mortality and morbidity logistic regression analysis was performed. Morbidity was assessed using the Clavien-Dindo Score. Major complications were defined as a C-D score ≥ 3. We also presented the data concerning need for reoperation and ICU admission.

RESULTS

85.9% of patients had at least one comorbidity. In the group of emergency patients age and number of comorbidities were independent risk factors of 30-day mortality and major morbidity. In elective patients age, dementia (OR:3.52; 95%CI:1.35-9.20) and kidney disease (OR:1.64; 95%CI:1.04-2.57) were found to be independent risk factors of 30-day postoperative mortality. Age (1.04; 95%CI:1.00-1.08) and heart disease (OR:1.30, 95%CI:1.04-1.63) were found to be independent risk factors of 30-day major morbidity.

CONCLUSIONS

In patients undergoing elective surgery 30-day mortality and morbidity was associated with age. 30-day mortality, but not morbidity was associated with kidney disease and dementia. 30-day morbidity, but not mortality, was associated with heart disease.

Aortic valve replacement among patients with Alzheimer's disease and related dementias

BACKGROUND

Transcatheter aortic valve replacement (TAVR) has made palliation from aortic stenosis more broadly available to populations previously thought to be too high risk for surgery, such as those with Alzheimer's disease and related dementias (ADRD); however, its safety and effectiveness in this context are uncertain.

METHODS

We performed a retrospective cohort study of national Medicare beneficiaries, aged 66 and older with Parts A and B, between 2010 and 2016. Patients undergoing AVR were identified, and follow-up was available through 2017. Multivariable regression was used to measure the independent association between having a diagnosis of ADRD at the time of AVR, stratified by TAVR and surgery, and outcomes (mortality and Medicare institutional days at 1 year after AVR).

RESULTS

The average rate of increase in AVR per year was 17.5 cases per 100,000 ADRD and 8.4 per 100,000 non-ADRD beneficiaries, largely driven by more rapid adoption of TAVR. Adjusted mortality following AVR declined significantly between those treated in 2010 and 2016, from 13.5% (95% CI 10.2%-17.7%) to 6.3% (95% CI 5.2%-7.6%) and from 13.7% (95% CI 12.7%-14.7%) to 6.3% (95% CI 5.8%-6.9%) in those with and without ADRD, respectively. The sharpest decline was noted for patients undergoing TAVR between 2011 and 2016, with adjusted mortality declining from 19.9% (95% CI 11.2%-32.8%) to 5.2% (95% CI 4.1%-6.5%) and from 12.2% (95% CI 9.3%-15.8%) to 5.0% (95% CI 4.4%-5.6%) in patients with and without ADRD, respectively. Similar declines were evident for Medicare institutional days in the year after AVR in both patient groups.

CONCLUSIONS

Rates of AVR in those with ADRD increased during the past decade largely driven by the diffusion of TAVR. The use of TAVR in this vulnerable population did not come at the expense of increasing Medicare institutional days or mortality at 1-year.

The co-occurrence of dementia in those with epilepsy is associated with 30-day readmission - A population-based study

OBJECTIVE

Dementia and epilepsy often co-occur and are associated with poor health outcomes and increased healthcare utilization. The literature on the association between readmission and co-occurrence of dementia and epilepsy is scant. Our objective was to determine if dementia in patients with epilepsy >40 years old is associated with 30-day hospital readmission, in-hospital mortality, discharge disposition, and length-of-stay.

METHODS

This retrospective cohort study used the 2014 Nationwide Readmissions Database, containing data from hospital discharges across the US and readmissions. Epilepsy and dementia were identified using previously validated ICD-9-CM codes. Primary outcome was 30-day readmission, analyzed with univariable and multivariable logistic regressions. Secondary outcomes were discharge disposition, in-hospital mortality, and length-of-stay, analyzed with univariable multinomial logistic, univariable logistic, and univariable ordinary least squared regressions, respectively. The top ten causes of readmission in each group were compared as well. All analyses accounted for survey weights, cluster, and stratum.

RESULTS

Patients with epilepsy with dementia (n = 15,588) had longer hospital stays [15% (95%CI 10-20%)], and higher odds of readmission [OR 1.11 (95%CI 1.05-1.17)], transfer to another facility [OR 2.18 (95%CI 1.93-2.46)], and in-hospital mortality [OR 1.50 (95%CI 1.25-1.79)] compared to those without dementia (n = 186,289).The top two causes of readmission were septicemia (dementia: 14.81%; no dementia: 9.45%) and epilepsy/convulsions (dementia: 5.91%; no dementia: 6.25%). Other top 10 causes of readmissions in those with epilepsy and dementia which were not present in those without dementia included delirium (5.21%), urinary tract infections (4.98%), and aspiration pneumonitis (4.29%).

SIGNIFICANCE

Dementia in epilepsy is associated with worse outcomes, including higher in-hospital mortality and higher readmissions. Potentially preventable causes of readmission in those with epilepsy and dementia were identified, including septicemia, delirium, urinary tract infection, and aspiration pneumonitis. Future studies are needed to inform interventions aimed at decreasing premature mortality and reducing potentially preventable readmissions in this vulnerable population.

Perioperative Care Strategy for Older Adults

Geriatric patients are not just older adult patients. Aging brings about unique physiologic, psychological, and sociologic changes within individuals. Recognition of these unique characteristics and measuring for their impact; instituting mitigating strategies; using age-specific anesthetic measures; and performing a systematic, algorithmic care model in the postoperative period overseen by a multidisciplinary team brings about enhanced outcomes and improved quality of care for this expanding group of patients.

Results of the Surgical Management of Acute Limb Ischemia in the Nonagenarians

BACKGROUND

The aging of the population leads us to treat older patients, in particular presenting with acute limb ischemia (ALI). However, there has been little evaluation of this pathology in the nonagenarians. The objectives of this work are thus to evaluate the 1-month and 1-year mortality of the nonagenarians treated for ALI, which made possible to determine the 1-year survival and to highlight the factors influencing the mortality.

METHODS

This is a monocentric retrospective study including all the patients aged 90 years old or more surgically treated for ALI between January 2012 and December 2016. In all the patients, we recorded the 1-month mortality and the 1-year survival and the demographic, clinical, and paraclinical data.

RESULTS

We operated 83 nonagenarians, with a majority of women (59, 71.1%), using general anesthesia in 20 patients (16.6%), including 10 cases of upper limb acute ischemia (12.0%). The overall mortality rate at 1 month was 22.9%, and the 1-year survival rate was 43.4%. Major amputation rate was 9.6% at 1 year. The survival of the patients operated for upper or lower limb ischemia was similar (P = 0.82). Univariate analysis showed that the 1-year survival was lower in patients having a history of cerebrovascular problems (P = 0.0003), heart failure (P = 0.0027), dementia (P = 0.0452), or in patients that were institutionalized (P = 0.0125), invalid (P = 0.0001), or presented with a complete acute ischemia (P = 0.0002). In multivariate analysis, 3 risk factors remained statistically significant: a previous history of cerebrovascular accident (hazard ratio [HR] = 3.05 [1.54-6.02]; P = 0.0014), cardiac failure (HR = 2.21 [1.23-3.97]; P = 0.0083), and complete ALI (HR = 3.07 [1.64-5.75]; P = 0.0005).

CONCLUSIONS

Our study showed that a history of cerebrovascular accident, cardiac failure, or complete ALI is a poor prognostic factor for the 1-year survival of nonagenarians dealt operated for ALI. These elements should be taken into account when deciding either to operate or not in this precise context.

Cognitive impairment assessment and interventions to optimize surgical patient outcomes

For elderly patients undergoing elective surgical procedures, preoperative evaluation of cognition is often overlooked. Patients may experience postoperative delirium (POD) and postoperative cognitive decline (POCD), especially those with certain risk factors, including advanced age. Preoperative cognitive impairment is a leading risk factor for both POD and POCD, and studies have noted that identifying these deficiencies is critical during the preoperative period so that appropriate preventive strategies can be implemented. Comprehensive geriatric assessment is a useful approach which evaluates a patient's medical, psycho-social, and functional domains objectively. Various screening tools are available for preoperatively identifying patients with cognitive impairment. The Enhanced Recovery After Surgery (ERAS) protocols have been discussed in the context of prehabilitation as an effort to optimize a patient's physical status prior to surgery and decrease the risk of POD and POCD. Evidence-based protocols are warranted to standardize care in efforts to effectively meet the needs of these patients.

Health outcomes of patients with dementia in acute care settings-A systematic review

BACKGROUND

An ageing population has resulted in increased numbers of people with dementia attending acute care services; however, the impact of hospitalisation on this population is uncertain.

PURPOSE

This systematic review aimed to synthesise the available evidence on adverse health outcomes for people with dementia in acute care settings.

METHODS

A systematic search of CINAHL, PubMed, MEDLINE, EMBASE and Scopus databases for primary research articles in English language, published from 2000 to 2017, was conducted. A protocol for the review was registered on the PROSPERO database.

RESULTS

The initial search identified 5,520 records. Following removal of duplicates and assessment against inclusion criteria, 13 studies were included in the final review. Findings identify associations between patients with dementia, longer length of hospital stay and higher mortality in some situations. Heterogeneity across studies in data reporting and outcomes prevented meta-analysis; therefore, results are presented narratively.

CONCLUSIONS

Certainty of findings from this review is impacted by variation in patient condition and data reporting. Additional rigorous studies on health outcomes for people with dementia during acute hospitalisation will contribute to the evidence.

IMPLICATIONS FOR PRACTICE

These findings along with further research examining outcomes for patients with dementia in acute care settings will inform provision of safer, quality care and optimal health outcomes for this vulnerable population.

["Memory acute"-treatment concept for inpatient remobilization of acutely ill patients with dementia]

BACKGROUND

Acute hospitals are generally not designed for people with dementia. Behavioral issues pose the greatest challenge. This article reports on the results of a prospective controlled study designed to assess whether dementia patients benefit from a remobilization strategy in a memory clinic (IG-MA) following hospital discharge.

METHODS

Between January and September 2018 patients with moderate to severe dementia discharged from hospital following acute episodes were admitted to an IG-MA for remobilization. The IG-MA unit provides specially qualified personnel and an adapted environment. Control groups were formed from the standard remobilization unit (KG1-AGR) and four care homes (KG2-PWH).

RESULTS

Patients in the IG-MA (n = 22) had a worse functional status at admission according to the Barthel index (BI), the timed "up and go" test (TUG) and the Esslinger transfer scale (ETS) than patients in the KG1-AGR (n = 59). Outcomes significantly improved in both groups (IG-MA and KG1-AGR) without a clear difference between groups: IG-MA (BI from 35 to 57.8 points, TUG from 30.8 s to 23 s, ETS from 2.1 to 1.1 points) vs. KG1-AGR (BI from 44.7 to 62.4 points, TUG from 28.6 s to 20.2 s, ETS from 1.7 to 0.9 points). There were differences in cognitive ability at admission (mini mental state examination, MMSE: IG-MA 13.6 points vs. KG1-AGR 20 points). The length of stay in the IG-MA was on average 5 days longer. Early discharge was mostly the result of complications and transfer to acute hospitals in the IG-MA group (22.7%) and in the KG1-AGR group this was mostly due to care issues (27.1%). The KG2-PWH group did not show any significant functional improvements in the first 4 weeks as measured by the BI.

CONCLUSION

Moderate to severely affected dementia patients with behavioral problems benefited from treatment in a specially designed remobilization unit following hospital discharge after an acute event.

Quality of life of patients with dementia in acute hospitals in Germany: a non-randomised, case-control study comparing a regular ward with a special care ward with dementia care concept

OBJECTIVES

To identify factors that predict the quality of life (QoL) of patients with dementia in acute hospitals and to analyse if a special care concept can increase patients' QoL.

DESIGN

A non-randomised, case-control study including two internal medicine wards from hospitals in Hamburg, Germany.

SETTING AND PARTICIPANTS

In all, 526 patients with dementia from two hospitals were included in the study (intervention: n=333; control: n=193). The inclusion criterion was an at least mild cognitive impairment or dementia. The intervention group was a hospital with a special care ward for internal medicine focusing on patients with dementia. The control group was from a hospital with a regular care ward without special dementia care concept.

OUTCOME MEASURES

Our main outcome was the QoL (range 0-100) from patients with dementia in two different hospitals. A Bayesian multilevel analysis was conducted to identify predictors such as age, dementia, agitation, physical and chemical restraints, or functional limitations that affect QoL.

RESULTS

QoL differs significantly between the control (40.7) and the intervention (51.2) group (p<0.001). Regression analysis suggests that physical restraint (estimated effect: -4.9), psychotropic drug use (-4.4) and agitation (-2.9) are negatively associated with QoL. After controlling for confounders, the positive effect of the special care concept remained (5.7).

CONCLUSIONS

A special care ward will improve the quality of care and has a positive impact on the QoL of patients with dementia. Health policies should consider the benefits of special care concepts and develop incentives for hospitals to improve the QoL and quality of care for these patients.

Dementia in elderly patients undergoing early cholecystectomy for acute cholecystitis: a retrospective observational study

Background

Dementia often adversely affects postoperative outcomes in surgical patients. This study evaluated postoperative outcomes among elderly patients with and without dementia undergoing early cholecystectomy for acute cholecystitis (AC).

Methods

A total of 182 patients over 85 years of age who were diagnosed with AC and treated from January 2005 to March 2018 were reviewed retrospectively; 59 patients who underwent early cholecystectomy were enrolled. The complication rates, length of postoperative hospital stay, and rates of routine discharge (i.e., returning to their preoperative living location) were compared between two groups of patients with and without dementia.

Results

The overall complication rate after early cholecystectomy for AC in 59 patients was 11.9%, and there was no mortality in this series. The median postoperative hospital stay was 9.0 days, and the routine discharge rate was 89.8%. Of the 59 patients, 22 patients (37.3%) had a history of dementia. Complication rates were comparable between the groups, despite the rate of delirium development being significantly higher in the dementia group. The median length of postoperative hospital stay and routine discharge rates did not significantly differ between groups.

Conclusions

Early cholecystectomy for patients with AC over 85 years of age was performed safely, and elderly patients with dementia had similar postoperative outcomes as compared with patients without dementia.

Feasibility and utility of a cognitive screening for risk stratification in hospitalized older patients

OBJECTIVES

To determine whether the Mini-Cog can be applied by nursing staff to hospitalized elderly patients for cognitive impairment associated risk stratification.

METHODS

This explorative prospective multicenter cohort study was carried out among 2522 patients aged 70 and older, hospitalized due to physical illness in eight hospitals in Rhineland-Palatinate, Germany. All patients were asked to conduct the Mini-Cog at the day of admission and were clustered into low-performance, intermediate-performance, and good-performance categories by trained nursing staff and two experienced geronto-psychiatrists as gold standard. Complications in the course of the treatment were monitored.

RESULTS

The Mini-Cog was conducted in 1398 (54%) out of 2522 eligible patients. Mini-Cog scores assessed by nursing staff differed from the gold standard in 327 cases (23.9%). According to the area under the curve (AUC), nursing staff identified cognitively low-performing patients almost as well as the geronto-psychiatrists (AUC = 0.862; 95% CI, 0.83-0.89; P < 0.001, accuracy 89.6%). Overall, 241 (17.6%) patients were classified as low performing. These patients had a significantly higher probability of suffering from at least one complication (odds ratio [OR] = 3.13; 95% CI, 2.09-4.70; calculated by a logistic regression model, adjusted for age), and they had a higher probability to show behavioral symptoms.

CONCLUSION

Even under naturalistic conditions, nursing staff detected cognitively low-performing inpatients with the Mini-Cog. Using this short screening instrument should enable to predict complications of hospitalized older patients associated with cognitive impairment, a precondition to implement targeted care for this vulnerable patient group.

Length of hospital stay and dementia: A systematic review of observational studies

OBJECTIVE

Hospitalizations of people with dementia (PWD) are often accompanied by complications or functional loss and can lead to adverse outcomes. Unsystematic findings suggest an influence of comorbidities on the extent of differences in the length of hospital stay (LOS). This systematic review aimed to identify and evaluate all studies reporting LOS in PWD as compared to PwoD in general hospitals.

METHODS

A systematic review of observational studies using PubMed and ISI Web of Knowledge. Inclusion criteria comprised original studies written in English or German, assessment of diagnosis of dementia, measurement of LOS, and comparison of people with and without dementia.

RESULTS

Fifty-two of 60 studies reported a longer hospitalization time for PWD compared to PwoD. The extent of the difference in LOS varied between and within countries as well as by type of primary morbidity (eg, injuries, cardiovascular diseases). The range of the LOS difference for studies without restriction to a primary morbidity was -2 to +22 days after matching or adjustment for a variable number and selection of potentially relevant covariates. For studies with injuries/fractures/medical procedures and infectious/vascular disease as the primary morbidity, the range was -2.9 to +12.4 and -11.2 to +21.8 days, respectively.

CONCLUSIONS

The majority of studies reported a longer hospitalization of PWD compared to PwoD. Length of hospital stay seems to be influenced by a variety of medical, social, organizational factors, including reasons for hospital admission, whose role should be explored in detail in further research.

Postoperative Outcomes in Primary Total Knee Arthroplasty Patients With Preexisting Cognitive Impairment: A Systematic Review

INTRODUCTION

To evaluate the body of evidence on the predictive value of preoperative cognitive impairment on in-hospital, short-term, and midterm postoperative outcomes for elderly patients undergoing total knee arthroplasty (TKA).

SIGNIFICANCE

With an aging population, an increasing percentage of the U.S. patient population will be living with cognitive impairment. There is currently no systematic review that assesses postoperative outcomes of patients with mild cognitive impairment (MCI) or preexisting diagnosis of dementia while undergoing elective primary TKA.

RESULTS

A database search between January 1, 1997, and November 1, 2017 in EMBASE, MEDLINE, and PubMed was conducted to identify articles that compared postoperative outcomes after TKA between patients aged 60 years with and without cognitive impairment. Cognitive impairment included preexisting diagnosis of dementia or MCI identified during preoperative assessment. Eligible articles were selected using dual reviewer and third-party arbitrator. The quality of the studies was evaluated using the Newcastle-Ottawa Scale. The strength of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach. A total of 6163 abstracts were screened. Only 11 full text articles met inclusion criteria, including 1 case-control, 5 prospective cohort, and 5 retrospective cohort studies. Two studies were of poor quality. Overall, there is moderate strength of evidence for increased risk of postoperative delirium, increased length of stay, and discharge to health-care facility among patients with preoperative MCI or preexisting dementia. The body of evidence is weak for other outcomes of interest including mortality, functionality and complications while in-hospital and in the short- and midterm.

CONCLUSION

This review highlights the need for additional good quality studies to provide more information about MCI and dementia as risk factors in primary TKA.

Care needs of people with dementia in the peri-operative environment: A systematic review

The care of people with dementia within the hospital setting is challenging for healthcare professionals. Hospital design and services are not optimized for people with dementia, owing to the lack of preparation of healthcare professionals and the busy environment of the acute hospital. The peri-operative environment may present particular difficulties but little is known about the experience and care of people with dementia in this setting. The aim of this review was to examine the care of surgical patients who have dementia and their family members in peri-operative environments and describe strategies adopted by healthcare professionals. A systematic search of the following databases was completed: BNI, CINAHL, PubMED and PsychINFO in accordance with PRISMA guidelines. Data were extracted and analysed within a thematic analysis framework as described by Braun and Clarke. Ten papers based on eight studies were included, five (n = 355,010 participants) containing quantitative data and five reporting qualitative data (n = 395 participants). People with dementia who go undergo surgery experienced higher adverse post-operative outcomes such as respiratory problems or urinary tract infections. The key elements in surgical care for people with dementia included: health assessment throughout the surgical trajectory (pre-, intra- and post-operative) and the resources used by healthcare professionals in the peri-operative care. Healthcare professionals reported difficulties in the completion of health assessments due to the cognitive status of people with dementia and a lack of skills in dementia management. The use of restraints was still a common practice and a source of conflict. Dementia-specific training and guidelines focused on the care of surgical patients who have dementia in peri-operative environments are required to improve care and post-operative outcomes. More research is required to develop effective interventions to improve care and decrease the risk of complications for people with dementia in the peri-operative care environment.

Nurses' knowledge about perioperative care of patients with neurological diseases

This study investigated the level of nurses' knowledge regarding the perioperative care of neurological patients. An author-developed questionnaire of 20 items was used in a sample of 94 hospital nurses serving in the neurology, surgery and anesthesiology departments and the intensive care unit. The average percentage of participants with correct answers was 49.2%. The mean value of participants' score was 9.8 ±3.4. Preexisting experience in the care of cases with multiple sclerosis and Parkinson's disease was positively related to the level of knowledge (p = 0.001 and 0.014 respectively). The ascertained level of nurses' knowledge regarding the perioperative care of neurological patients was moderate, questioning their adequacy to handle such cases. Previous experience in the care of particular diseases had significantly positive impact on knowledge, suggesting potential improvement strategies through targeted education and specialization of nurses. In conclusion, nurse's knowledge regarding perioperative care of neurological patients was insufficient, requiring appropriate improvement interventions.

The effects of pre-existing dementia on surgical outcomes in emergent and nonemergent general surgical procedures: assessing differences in surgical risk with dementia

BACKGROUND

The aim was to assess the morbidity and in-hospital mortality that occur in surgical patients with pre-existing dementia compared with those outcomes in non-dementia patients following emergent and nonemergent general surgical operations.

METHODS

A total of 120 patients with dementia were matched for sex and type of surgery with 120 patients who did not have dementia, taken from a cohort of 15,295 patients undergoing surgery, in order to assess differences in surgical risk with dementia. Patient information was examined, including sex, body mass index (BMI), prevalence of individual comorbidities at admission, and several other variables that may be associated with postoperative outcomes as potential confounders.

RESULTS

Patients with dementia tended to have a higher overall complication burden compared to those without. This was evidenced by a higher average number of complications per patient (3.30 vs 2.36) and a higher average score on the comprehensive complication index (48.61 vs 37.60), values that were statistically significant for a difference between the two groups. The overall in-hospital mortality in patients with dementia was 28.3% (34 deaths out of 120 patients). During the same period, at our hospital, the overall in-hospital mortality in the control group was 20% (24 deaths out of 120 patients). Patient groups with and without dementia each had 3 and 5 associated risk factors for morbidity and 9 and 12 risk factors for mortality, respectively.

CONCLUSIONS

Patients with pre-existing dementia have a greater than average risk of early death after surgery, and their incidence of fatal complications is higher than that of surgical patients without dementia.

Lower Postsurgical Mortality for Individuals with Dementia with Better-Educated Hospital Workforce

OBJECTIVES

To investigate whether care in a hospital with more nurses holding at least a Bachelor of Science in Nursing (BSN) degree is associated with lower mortality for individuals with Alzheimer's disease and related dementias (ADRD) undergoing surgery ADRD.

DESIGN

Cross-sectional data from 2006-07 Medicare claims were linked with the Multi-State Nursing Care and Patient Safety Survey of nurses in 4 states.

SETTING

Adult, nonfederal, acute care hospitals in California, Florida, New Jersey, and Pennsylvania (N=531).

PARTICIPANTS

Medicare beneficiaries aged 65 and older with and without ADRD undergoing general, orthopedic, or vascular surgery (N=353,333; ADRD, n=46,163; no ADRD, n=307,170).

MEASUREMENTS

Thirty-day mortality and failure to rescue (death after a complication).

RESULTS

Controlling for hospital, procedure, and individual characteristics, each 10% increase in the proportion of BSN nurses was associated with 4% lower odds of death (odds ratio (OR)=0.96, 95% confidence interval (CI)=0.93-0.98) for individuals without ADRD, but 10% lower odds of death (OR=0.90, 95% CI=0.87-0.94) for those with ADRD. Each 10% increase in the proportion of nurses holding a BSN degree or higher was associated with 5% lower odds of failure to rescue (OR=0.95, 95% CI=0.92-0.98) for individuals without ADRD but 10% lower odds of failure to rescue (OR=0.90, 95% CI=0.87-0.94) for those with ADRD.

CONCLUSION

Individuals undergoing surgery who have coexisting ADRD are more likely to die within 30 days of admission and die after a complication than those without ADRD. Having more BSN nurses in the hospital improves the odds of good outcomes for all individuals and has a much greater effect in individuals with ADRD.

Surgical outcomes for patients diagnosed with dementia: A coarsened exact matching study

BACKGROUND

An increasing number of elderly patients with dementia are undergoing surgical operations. Little is known about the differential impact of dementia on surgical outcomes. We investigated whether demented patients undergoing surgical operations have worse outcomes than their non-demented counterparts.

METHODS

We performed a cohort study of all patients undergoing a series of surgical operations who were registered in the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2009 to 2013. We examined the association of dementia with inpatient case-fatality, discharge to a facility, and length of stay (LOS). Coarsened exact matching was used to balance comorbidities among the comparison groups, and mixed effect methods were used to control for clustering at the hospital level.

RESULTS

During the study period, 342,075 patients underwent surgical operations that met the inclusion criteria. Multivariable logistic regression models, after coarsened exact matching, demonstrated that demented patients were not associated with higher case-fatality (OR, 0.43; 95% CI, 0.13-1.36), but were associated with higher rates of discharge to a facility (OR, 1.71; 95% CI, 1.26-2.31) and longer LOS (Adjusted difference, 31%; 95% CI, 26%-36%). These persisted in pre-specified subgroups stratified on particular operations.

CONCLUSIONS

Using a comprehensive all-payer cohort of surgical patients in New York State we identified an association of dementia with increased rate of discharge to rehabilitation and longer LOS. No difference was identified in the case fatality of the two groups. Policy makers, payers, and physicians should take these findings into account when designing new policies, and when counseling patients.

Predicting excess cost for older inpatients with clinical complexity: A retrospective cohort study examining cognition, comorbidities and complications

BACKGROUND

Hospital-acquired complications increase length of stay and contribute to poorer patient outcomes. Older adults are known to be at risk for four key hospital-acquired complications (pressure injuries, pneumonia, urinary tract infections and delirium). These complications have been identified as sensitive to nursing characteristics such as staffing levels and level of education. The cost of these complications compared to the cost of admission severity, dementia, other comorbidities or age has not been established.

METHOD

To investigate costs associated with nurse-sensitive hospital-acquired complications in an older patient population 157,178 overnight public hospital episodes for all patients over age 50 from one Australian state, 2006/07 were examined. A retrospective cohort study design with linear regression analysis provided modelling of length-of-stay costs. Explanatory variables included patient age, sex, comorbidities, admission severity, dementia status, surgical status and four complications. Extra costs were based on above-average length-of-stay for each patient's Diagnosis Related Group from hospital discharge data.

RESULTS

For adults over 50 who have length of stay longer than average for their diagnostic condition, comorbid dementia predicts an extra cost of A$874, (US$1,247); any one of four key complications predicts A$812 (US$1,159); each increase in admission severity score predicts A$295 ($US421); each additional comorbidity predicts A$259 (US$370), and for each year of age above 50 predicts A$20 (US$29) (all estimates significant at p<0.0001).

DISCUSSION

Hospital-acquired complications and dementia cost more than other kinds of inpatient complexity, but admission severity is a better predictor of excess cost. Because complications are potentially preventable and dementia care in hospitals can be improved, risk-reduction strategies for common complications, particularly for patients with dementia could be cost effective.

CONCLUSIONS

Complications and dementia were found to cost more than other kinds of inpatient complexity.

Prediction of mortality and morbidity in head and neck cancer patients 80 years of age and older undergoing surgery

OBJECTIVES

To determine postoperative complications and mortality rates in octogenarian and older head and neck cancer patients undergoing ablative surgical resections and to identify factors associated with postoperative morbidity and mortality.

METHODS

Retrospective cohort study investigating risk factors for 30-day serious complication risk and 90-day mortality risk for patients aged 80 years and older who underwent ablative head and neck oncologic surgical procedures at an academic tertiary care center between 2005 and 2015.

RESULTS

Of the 219 patients who underwent 241 surgeries, 74 patients experienced serious complications within 30 days and 25 died within 90 days of surgery. American Society of Anesthesiologists (ASA) score of 4 or greater, and operating room (OR) time ≥6 hours were independently associated with serious complications, whereas age ≥90 years, overall severe comorbidity score, presence of preoperative dysphagia, and large extent of resection were associated with increased risk of death in 90 days. Models to predict risk of 30-day serious complications and 90-day mortality were then developed.

CONCLUSION

Patient and surgical treatment factors predict risk of serious complications and mortality in patients aged 80 years and older undergoing ablative head and neck surgery. Predictive models may guide preoperative discussion with patients.

Poorer outcomes and greater healthcare costs for hospitalised older people with dementia and delirium: a retrospective cohort study

OBJECTIVE

To compare healthcare utilisation outcomes among older hospitalised patients with and without cognitive impairment, and to compare the costs associated with these outcomes.

METHODS

Retrospective cohort study of administrative data from a large teaching hospital in Melbourne, Australia from 1 July 2006 to 30 June 2012. People with cognitive impairment were defined as having dementia or delirium coded during the admission. Outcome measures included length of stay, unplanned readmissions within 28 days and costs associated with these outcomes. Regression analysis was used to compare differences between those with and without cognitive impairment.

RESULTS

There were 93 300 hospital admissions included in the analysis. 6459 (6.9%) involved cognitively impaired patients. The adjusted median length of stay was significantly higher for the cognitively impaired group compared with the non-cognitively impaired group (7.4 days 6.7-10.0 vs 6.6 days, interquartile range 5.7-8.3; p < 0.001). There were no differences in odds of 28-day readmission. When only those discharged back to their usual residence were included in the analysis, the risk of 28-day readmission was significantly higher for those with cognitive impairment compared with those without. The cost of admissions involving patients with cognitive impairment was 51% higher than the cost of those without cognitive impairment.

CONCLUSIONS

Hospitalised people with cognitive impairment experience significantly greater length of stay and when discharged to their usual residence are more likely to be readmitted to hospital within 28 days compared with those without cognitive impairment. The costs associated with hospital episodes and 28-day readmissions are significantly higher for those with cognitive impairment. Copyright © 2016 John Wiley & Sons, Ltd.

Development of cognitive screening test for the severely hearing impaired: Hearing-impaired MoCA

OBJECTIVES

To develop a version of the Montreal Cognitive Assessment (MoCA) to be administered to the severely hearing impaired (HI-MoCA), and to assess its performance in two groups of cognitively intact adults over the age of 60.

STUDY TYPE

Test development followed by prospective subject recruitment.

METHODS

The MoCA was converted into a timed PowerPoint (Microsoft Corp., Redmond, WA) presentation, and verbal instructions were converted into visual instructions. Two groups of subjects over the age of 60 were recruited. All subjects passed screening questionnaires to eliminate those with undiagnosed mild cognitive impairment. The first group had normal hearing (group 1). The second group was severely hearing impaired (group 2). Group 1 received either the MoCA or HI-MoCA test (T1). Six months later (T2), subjects were administered the test (MoCA or HI-MoCA) they had not received previously to determine equivalency. Group 2 received the HI-MoCA at T1 and again at T2 to determine test-retest reliability.

RESULTS

One hundred and three subjects were recruited into group 1, with a score of 26.66 (HI-MoCA) versus 27.14 (MoCA). This was significant (P < 0.05), but scoring uses whole numerals and the 0.48 difference was found not clinically significant using post hoc sensitivity analyses. Forty-nine subjects were recruited into group 2. They scored 26.18 and 26.49 (HI-MoCA at T1 and T2). No significance was noted (P > 0.05), with a test-retest coefficient of 0.66.

CONCLUSION

The HI-MoCA is easy to administer and reliable for screening cognitive impairment in the severely hearing impaired. No conversion factor is required in our prospectively tested cohort of cognitively intact subjects.

The association between dementia and epilepsy: A systematic review and meta-analysis

OBJECTIVE

Dementia is among the top 15 conditions with the most substantial increase in burden of disease in the past decade, and along with epilepsy, among the top 25 causes of years lived with disability worldwide. The epidemiology of dementia in persons with epilepsy, and vice versa, is not well characterized. The purpose of this systematic review was to examine the prevalence, incidence, and reported risk factors for dementia in epilepsy and epilepsy in dementia.

METHODS

Embase, PsycINFO, MEDLINE, and the Cochrane databases were searched from inception. Papers were included if they reported the incidence and/or prevalence of dementia and epilepsy. Two individuals independently performed duplicate abstract and full-text review, data extraction, and quality assessment. Random-effects models were used to generate pooled estimates when feasible.

RESULTS

Of the 3,043 citations identified, 64 were reviewed in full text and 19 articles were included. The period prevalence of dementia ranged from 8.1 to 17.5 per 100 persons among persons with epilepsy (insufficient data to pool). The pooled period prevalence of epilepsy among persons with dementia was 5 per 100 persons (95% confidence interval [CI] 1-9) in population-based settings and 4 per 100 persons (95% CI 1-6) in clinic settings. There were insufficient data to report a pooled overall incidence rate and only limited data on risk factors.

SIGNIFICANCE

There are significant gaps in knowledge regarding the epidemiology of epilepsy in dementia and vice versa. Accurate estimates are needed to inform public health policy and prevention, and to understand health resource needs for these populations.

Do Patients with Pre-Existing Psychiatric Illness Have an Increased Risk of Infection after Injury?

BACKGROUND

Trauma remains a leading cause of death and long term-morbidity. We have shown that patients who sustain traumatic injuries are at increased risk for the development of infectious complications. Psychiatric illnesses (PIs) are also noted to occur frequently among the general population. The presence of a PI has been shown to be a risk factor for the development of infections. Despite the prevalence of both traumatic injuries and psychiatric diseases, there are little data relating the impact of PI on the outcome of patients with trauma. We hypothesize that the presence of a PI will be associated with an increased risk of an infection developing after injury.

PATIENTS AND METHODS

This is a five year retrospective chart review of all admitted patients with trauma age 18 years and older. Patients with and without a major psychiatric illness were compared. Demographic data, mechanism of injury and Injury Severity Score (ISS) were reviewed. Co-morbidities included diabetes mellitus, obesity, pre-injury steroid use, and International Classification of Diseases, 9th edition, based psychiatric illness. All infections were diagnosed by microbiologic criteria (urinary tract infection [UTI], ventilator-associated pneumonia) or Centers for Disease Control and Prevention criteria for clinically evident infections (surgical site infection).

RESULTS

Of the 11,147 admitted trauma patients, 14.5% had a pre-injury PI diagnosis. The PI patients were older (61.5 ± 0.5 vs. 54.3; p < 0.001), more often female (56% vs. 39.1%; p < 0.001), and had no difference in blunt mechanism rates (88.4% vs. 89.9%; p = 0.06) or median ISS (9 vs. 9; p = 0.06). There was no difference between PI and non-PI patients in pre-injury diabetes mellitus (13.4% vs. 12.7%; p = 0.4), steroid use (2.5% vs. 1.9%; p = 0.1), but patients with PI were more likely to be obese (15.7% vs. 13.6%; p = 0.03). Patients with PI were more likely to have an infection develop (10.4% vs. 7.5%; p < 0.001). The most common infection in both groups was UTI (6.9% vs. 4.2%; p < 0.001). Compared with non-PI patients, adjusting for age, gender, ISS, diabetes mellitus, and obesity, patients with PI were more likely to have an infection develop (odds ratio 1.3, 95% confidence interval = 1.1-1.5) Conclusions: Patients with an underlying PI are at increased risk of having a UTI after traumatic injury. This study identifies a previously unknown independent risk factor for UTIs in patients with trauma. This stresses the need for increased awareness and attention to this vulnerable population.

[Impact of dementia on length of stay and costs in acute care hospitals]

BACKGROUND

The treatment of patients with dementia in acute care hospitals is becoming increasingly more important. The aim of this study was to investigate and demonstrate aspects of the healthcare situation and resource consumption of dementia patients during their hospital stay in a ward for internal medicine.

MATERIAL AND METHODS

Secondary data from a ward of internal medicine were analyzed on a retrospective and case-related basis. For 100 patients a diagnosis of dementia by a general practitioner before hospitalization was identified. The control group was selected by age and sex from the other patients in the ward (n = 100). The costs were calculated on the basis of the German diagnosis-related groups (G-DRG) flat rate case classification. The relationship between dementia, deviation from the average length of stay and costs was investigated under the control of comorbidities using multivariate regression analysis.

RESULTS

Patients with dementia had poorer health at admission with respect to functionality and orientation and a higher risk of falls and pressure ulcers. During hospitalization patients with dementia fell more frequently than patients without dementia (12 % versus 3 %, p = 0.029). Regarding the average length of stay, according to the G‑DRG catalogue patients with dementia stayed 1.4 days longer in hospital than patients without dementia and caused excess costs of 19 %.

CONCLUSION

Patients with dementia are a highly vulnerable patient group with a higher consumption of resources than patients without dementia. The results demonstrate the care-related and economic consequences, which the increasing number of patients with dementia could have in the future.

The Influence of Psychiatric Comorbidity on Inpatient Outcomes following Distal Humerus Fractures

Background. The influence of psychiatric comorbidity on outcomes following inpatient management of upper extremity fractures is poorly understood. Methods. The National Hospital Discharge Survey was queried to identify patients admitted to US hospitals with distal humerus fractures between 1990 and 2007. Patients were subdivided into 5 groups: depression, anxiety, schizophrenia, dementia, and no psychiatric comorbidity. Multivariable logistic regression analysis identified independent risk factors for adverse events, requirement of blood transfusion, and discharge to another inpatient facility. Results. A cohort representative of 526,185 patients was identified as having a distal humerus fracture. Depression, anxiety, and dementia were independently associated with higher odds of in-hospital adverse events (P<0.001). Depression was associated with higher odds of inpatient blood transfusion (P<0.001). Depression, schizophrenia, and dementia were associated with higher odds of nonroutine discharge to another inpatient facility (P<0.001). Patients with a diagnosis of schizophrenia had a mean of 12 (P<0.001) more days of care than patients with no psychiatric comorbidity. Discussion. Patients with comorbid psychiatric illness who are admitted to hospitals with distal humerus fractures are at increased risk of inpatient adverse events and posthospitalization care.
