RESUMO

Focused ultrasound can be used to rapidly diagnose COVID-19 disease, assess disease severity, and inform management of COVID-19 and associated pathologies, reducing radiation exposure from other imaging modalities and minimizing spread of infection. Ultrasound examinations performed by trained nurses in the intensive care unit (ICU) enable more patients to receive these assessments. This case series evaluates the use of nurse-led focused cardiac and lung ultrasound for clinical management of ICU patients with COVID-19. We describe common pathophysiological findings and how findings were used to inform clinical decision-making. An ultrasound trained ICU nurse performed Focused Ultrasound in Intensive Care (FUSIC) cardiac and lung scans enabling calculation of a lung severity score on adult ICU patients with a confirmed COVID-19 diagnosis in a single-centre setting. Fifteen scans were performed on 15 patients. Thirteen (87%) patients had normal left ventricular function; 12 (80%) normal right ventricular function. All 15 (100%) scans identified abnormal lung findings including irregular thickened pleura, B-lines, sub-pleural consolidation and hepatization. Worse lung severity scores were correlated with higher Acute Physiology and Chronic Health Evaluation (APACHE II) scores (r = 0.70; p = .003). Of the 15 scans, 10 (67%) identified abnormal pathology contributing to a change in clinical management. This included targeted fluid removal (4, 27%), change in respiratory management (3, 20%) and need for formal echocardiographic assessment (3, 20%). Findings from five (33%) scans required no intervention. This case series demonstrates nurse-led ultrasound could be a useful adjunct in the management of the COVID-19 patient.

RESUMO

FUSIC haemodynamics (HD) - the latest Focused Ultrasound in Intensive Care (FUSIC) module created by the Intensive Care Society (ICS) - describes a complete haemodynamic assessment with ultrasound based on ten key clinical questions: 1. Is stroke volume abnormal? 2. Is stroke volume responsive to fluid, vasopressors or inotropes? 3. Is the aorta abnormal? 4. Is the aortic valve, mitral valve or tricuspid valve severely abnormal? 5. Is there systolic anterior motion of the mitral valve? 6. Is there a regional wall motion abnormality? 7. Are there features of raised left atrial pressure? 8. Are there features of right ventricular impairment or raised pulmonary artery pressure? 9. Are there features of tamponade? 10. Is there venous congestion? FUSIC HD is the first system of its kind to interrogate major cardiac, arterial and venous structures to direct time-critical interventions in acutely unwell patients. This article explains the rationale for this accreditation, outlines the training pathway and summarises the ten clinical questions. Further details are included in an online supplementary appendix.

RESUMO

INTRODUCTION: The non-invasive analysis of body fluid composition with bio-electrical impedance analysis (BIA) provides additional information allowing for more persona-lised therapy to improve outcomes. The aim of this study is to assess the prognostic value of fluid overload (FO) in the first week of intensive care unit (ICU) stay. MATERIAL AND METHODS: A retrospective, observational analysis of 101 ICU patients. Whole-body BIA measurements were performed, and FO was defined as a 5% increase in volume excess from baseline body weight. RESULTS: Baseline demographic data, including severity scores, were similar in both the fluid overload-positive (FO+, n = 49) patients and in patients without fluid overload (FO-, n = 52). Patients with FO+ had significantly higher cumulative fluid balance during their ICU stay compared to those without FO (8.8 ± 7.0 vs. 5.5 ± 5.4 litres; P = 0.009), VE (9.9 ± 6.5 vs. 1.5 ± 1.5 litres; P < 0.001), total body water (63.0 ± 9.5 vs. 52.8 ± 8.1%; P < 0.001), and extracellular water (27.0 ± 7.3 vs. 19.6 ± 3.7 litres; P < 0.001). The presence of 5%, 7.5%, and 10% fluid overload was directly associated with increased ICU mortality rates. The percentage fluid overload (P = 0.039) was an independent predictor for hospital mortality. CONCLUSIONS: A higher mortality rate in ICU-patients with FO was observed. FO is an independent prognostic factor because neither APACHE-II, SOFA, nor SAPS-II significantly differed on admission between survivors and non-survivors. Further research is needed to confirm these data prospectively and to evaluate whether BIA-guided deresuscitation in the subacute phase will improve mortality rates.

RESUMO

BACKGROUND: Agitation and delirium are common in mechanically ventilated adult intensive care unit (ICU) patients and may contribute to delayed extubation times. Difficult-to-wean ICU patients have been associated with an increased risk of longer ICU length of stays and mortality. The purpose of this systematic review and meta-analysis is to evaluate the evidence of dexmedetomidine facilitating successful mechanical ventilation extubation in difficult-to-wean ICU patients and clinical outcomes. METHODS: A literature search was conducted using MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Global Health, Cochrane Central Register of Controlled Trials, Clinical Trial Registries, and the Health Technology Assessment Database from inception to December 5, 2019. Randomized controlled trials evaluating dexmedetomidine with the intended purpose to facilitate mechanical ventilation liberation in adult ICU patients (≥18 years) experiencing extubation failure were included. The primary outcome of time to extubation was evaluated using the weighted mean difference (WMD), with a random effects model. Secondary analyses included hospital and ICU length of stay, in-hospital mortality, hypotension, and bradycardia. RESULTS: A total of 6 trials (n = 306 patients) were included. Dexmedetomidine significantly reduced the time to extubation (WMD: -11.61 hours, 95% CI: -16.5 to -6.7, P = .005) and ICU length of stay (WMD: -3.04 days; 95% CI: -4.66 to -1.43). Hypotension risk was increased with dexmedetomidine (risk ratio [RR]: 1.62, 95% CI: 1.05-2.51), but there was no difference in bradycardia risk (RR: 3.98, 95% CI: 0.70-22.78). No differences were observed in mortality rates (RR: 1.30, 95% CI: 0.45-3.75) or hospital length of stay (WMD: -2.67 days; 95% CI: -7.73 to 2.39). CONCLUSIONS: Dexmedetomidine was associated with a significant reduction in the time to extubation and shorter ICU stay in difficult-to-wean ICU patients. Although hypotension risk was increased with dexmedetomidine, no differences in other clinical outcomes were observed.

RESUMO

BACKGROUND: The prevalence of dementia in Tanzania, as in other developing countries, is progressively increasing. Yet international screening instruments for mild cognitive impairment are lacking. OBJECTIVES: The aim of this study was to determine the psychometrics and the diagnostic ability of the Montreal Cognitive Assessment 5 minutes protocol (MoCA-5-min) among older adults in the rural Tanzania. METHODS: The MoCA-5-min and the Identification and Intervention for Dementia in Elderly Africans (IDEA) cognitive screening were concurrently administered through face to face to 202 community-dwelling older adults in Chamwino district. Exploratory factor analysis (EFA) using principal component method and oblique rotation was performed to determine the underlying factor structure of the scale. The concurrent and construct as well as predictive validities of the MoCA-5-min were examined by comparing its score with IDEA cognitive screening and psychiatrist's diagnosis using DSM-V criteria, respectively. RESULTS: The EFA found that all the MoCA-5-min items highly loaded into one component, with factor loading ranging from 0.550 to 0.879. The intraclass correlation coefficient for 6 weeks test-retest reliability was 0.85. Its strong significant correlation with the IDEA screening (Pearson's r = 0.614, p < 0.001) demonstrated a good concurrent validity. Using the psychiatrist's rating as the gold standard, MoCA-5-min demonstrated the optimal cut-off score for MCI at 22, which yielded the sensitivity of 80% and specificity of 74%; and dementia at score of 16 giving a sensitivity of 90% and specificity of 80%. Upon stratifying the sample into different age groups, the optimal cut-off scores tended to decrease with the increase in age. CONCLUSION: The MoCA-5-min is reliable and provides a valid and accurate measure of cognitive decline among older population in the rural settings of Tanzania. The use of varying cut-off scores across age groups may ensure more precise discriminatory power of the MoCA-5-min. IMPLICATIONS FOR PRACTICE: Availability of the MoCA-5-min in Tanzania will facilitate clinicians to timely detect dementia at both pre-clinical and clinical stages. Its availability will also encourage further research and international collaborations in dementia prevention programs.

RESUMO

BACKGROUND/OBJECTIVES: Federally-mandated consultant pharmacist-conducted retrospective medication regimen reviews (MRRs) are designed to improve medication safety in nursing homes (NH). However, MRRs are potentially ineffective. A new model of care that improves access to and efficiency of consultant pharmacists is needed. The objective of this study was to determine the impact of pharmacist-led telemedicine services on reducing high-risk medication adverse drug events (ADEs) for NH residents using medication reconciliation and prospective MRR on admission plus ongoing clinical decision support alerts throughout the residents' stay. DESIGN: Quality improvement study using a stepped-wedge design comparing the novel service to usual care in a one-year evaluation from November 2016 to October 2017. SETTING: Four NHs (two urban, two suburban) in Southwestern Pennsylvania. PARTICIPANTS: All residents in the four NHs were screened. There were 2,127 residents admitted having 652 alerts in the active period. INTERVENTION: Upon admission, pharmacists conducted medication reconciliation and prospective MRR for residents and also used telemedicine for communication with cognitively-intact residents. Post-admission, pharmacists received clinical decision support alerts to conduct targeted concurrent MRRs and telemedicine. MEASUREMENT: Main outcome was incidence of high-risk medication, alert-specific ADEs. Secondary outcomes included all-cause hospitalization, 30-day readmission rates, and consultant pharmacists' recommendations. RESULTS: Consultant pharmacists provided 769 recommendations. The intervention group had a 92% lower incidence of alert-specific ADEs than usual care (9 vs 31; 0.14 vs 0.61/1,000-resident-days; adjusted incident rate ratio (AIRR) = 0.08 (95% confidence interval (CI) = 0.01-0.40]; P = .002). All-cause hospitalization was similar between groups (149 vs 138; 2.33 vs 2.70/1,000-resident-days; AIRR = 1.06 (95% CI = 0.72-1.58); P = .75), as were 30-day readmissions (110 vs 102; 1.72 vs 2.00/1,000-resident-days; AIRR = 1.21 (95% CI = 0.76-1.93); P = .42). CONCLUSIONS: This is the first evaluation of the impact of pharmacist-led patient-centered telemedicine services to manage high-risk medications during transitional care and throughout the resident's NH stay, supporting a new model of patient care.

RESUMO

Objective: To estimate the national cost of ADEs resulting from inappropriate medication-related alert overrides in the U.S. inpatient setting. Materials and Methods: We used three different regression models (Basic, Model 1, Model 2) with model inputs taken from the medical literature. A random sample of 40 990 adult inpatients at the Brigham and Women's Hospital (BWH) in Boston with a total of 1 639 294 medication orders was taken. We extrapolated BWH medication orders using 2014 National Inpatient Sample (NIS) data. Results: Using three regression models, we estimated that 29.7 million adult inpatient discharges in 2014 resulted in between 1.02 billion and 1.07 billion medication orders, which in turn generated between 75.1 million and 78.8 million medication alerts, respectively. Taking the basic model (78.8 million), we estimated that 5.5 million medication-related alerts might have been inappropriately overridden, resulting in approximately 196 600 ADEs nationally. This was projected to cost between $871 million and $1.8 billion for treating preventable ADEs. We also estimated that clinicians and pharmacists would have jointly spent 175 000 hours responding to 78.8 million alerts with an opportunity cost of $16.9 million. Discussion and Conclusion: These data suggest that further optimization of hospitals computerized provider order entry systems and their associated clinical decision support is needed and would result in substantial savings. We have erred on the side of caution in developing this range, taking two conservative cost estimates for a preventable ADE that did not include malpractice or litigation costs, or costs of injuries to patients.

RESUMO

OBJECTIVE: Repeated testing using the Montreal Cognitive Assessment (MoCA) increases risks for practice effects which may bias measurements of cognitive change. The objective of this study is to develop two alternate versions of the MoCA (Hong Kong version; HK-MoCA) and to investigate the validity and reliability of the alternate versions in patients with DSM-5 Mild Neurocognitive Disorder (Mild NCD) and cognitively healthy controls. METHODS: Concurrent validity and inter-scale agreement were examined by Pearson correlation of the total scores between the original and alternate versions and the Bland-Altman Method. Criterion validity of the two alternate versions in differentiating patients with Mild NCD was tested using receiver operating characteristic curve (ROC) analysis. One-month test-retest and inter-rater reliability were examined in 20 participants. Internal consistency of the alternate versions was measured by the Cronbach's α. RESULTS: 30 controls (age 73.4 [4.5] years, 60% female) and 30 patients (age 75.4 [5.5] years, 73% female) with Mild NCD were recruited. Both alternate versions significantly correlated with the original version (r = 0.79-0.87, p<0.001). Mean differences of 0.17 and -0.40 points were found between the total scores of the alternate with the original versions with a consistent level of agreement observed throughout the range of cognitive abilities. Both alternate versions significantly differentiated patients with Mild NCD from healthy controls (area under ROC 0.922 and 0.724, p<0.001) and showed good one-month test-retest reliability (intra-class correlation [ICC] = 0.92 and 0.82) and inter-rater reliability (ICC = 0.99 and 0.87) and high internal consistency (Cronbach α = 0.79 and 0.75). CONCLUSION: The two alternate versions of the HK-MoCA are useful for Mild NCD screening.

RESUMO

Cognitive impairment is a major factor contributing to poor functional outcome after subarachnoid hemorrhage caused by a ruptured cerebral aneurysm (aSAH). Montreal Cognitive Assessment (MoCA) has been shown to be superior to the Mini-Mental State Examination in screening for cognitive domain deficit and correlating to functional outcome in aSAH patients. The aim of the current study was to determine the Montreal Cognitive Assessment (MoCA) score change that was associated with change of health in general in an aSAH patient cohort. We recruited aSAH patients from a regional neurosurgical center over a 3-year period. Patient assessments including MoCA and global rating of change (GRoC) were carried out at at 3 and 12months after aSAH. Anchor-based and distribution-based approaches were adopted to calculate the Minimum Clinically Important Difference (MID). One hundred and seventy-five aSAH patients completed both 3-month and 1-year assessments and consented for participation. Employing the distribution-based approach for the 3-month and 1-year MoCA scores, the MID estimates equated to a change of 2.0 and 1.1 respectively. Employing the anchor-based approach (with GRoC), the MID estimate of MoCA (median, IQR) was 2, 1-4. In conclusion, we found that the MID of MoCA score associated with change of health in general in aSAH patients was 2. The MID provides guidance for future clinical trial design targeting on cognitive dysfunction after aSAH.

RESUMO

Health-related quality of life measurements, are commonly used to quantify burden of disease, to evaluate treatment method, and to facilitate benchmarking. The aim of the current study was to determine the Clinically Important Difference (CID) for a Chinese version of Stroke-specific Quality of Life (SS-QOL) in an aneurysmal subarachnoid hemorrhage (SAH) patient cohort. The study recruited SAH patients in a neurosurgical unit in Hong Kong. SAH patients who completed both 3-month and 1-year assessments were included in the analysis. The study received ethical approvals from the joint CUHK-NTEC Clinical Ethics Committee and written informed consent was obtained from all participants or their next of kins. Over a 2-year period, 65 eligible patients were included in the study. Employing the anchor-based approach with global rating of change, the CID estimate of SS-QOL total score was 4.7 (95% confidence interval [CI]: 2.5-5.3), the CID estimate for SSQOL physical subscore was 2.1 (95% CI: 0.3-2.4), and the CID estimate for SS-QOL psychosocial subscore change was 2.8 (95% CI: 1.8-3.7). In conclusion, our study defined the CID for SS-QOL applied to SAH patients and should be further validated in another SAH patient population.

RESUMO

BACKGROUND: Estimates of the burden of disease caused by a particular agent are used to assist in making policy and prioritizing actions. Most estimations have employed the attributable fraction approach, which estimates the proportion of disease cases or deaths in a specific year which are attributable to past exposure to a particular agent. While this approach has proven extremely useful in quantifying health effects, it requires historical data on exposures which are not always available. METHODS: We present an alternative method, the future excess fraction method, which is based on the lifetime risk approach, and which requires current rather than historical exposure data. This method estimates the future number of exposure-related disease cases or deaths occurring in the subgroup of the population who were exposed to the particular agent in a specific year. We explain this method and use publically-available data on current asbestos exposure and mesothelioma incidence to demonstrate the use of the method. CONCLUSIONS: Our approach to modelling burden of disease is useful when there are no historical measures of exposure and where future disease rates can be projected on person years at risk.

RESUMO

BACKGROUND AND PURPOSE: The objective of this study is to examine the discrepancy between single versus age and education corrected cutoff scores in classifying performance on the Montreal Cognitive Assessment (MoCA) in patients with stroke or transient ischemic attack. METHODS: MoCA norms were collected from 794 functionally independent and stroke- and dementia-free persons aged ≥65 years. magnetic resonance imaging was used to exclude healthy controls with significant brain pathology and medial temporal lobe atrophy. Cutoff scores at 16th, 7th, and 2nd percentiles by age and education were derived for the MoCA and MoCA 5-minute Protocol. MoCA performance in 919 patients with stroke or transient ischemic attack was classified using the single and norm-derived cutoff scores. RESULTS: The norms for the Hong Kong version of the MoCA total and domain scores and the total score of the MoCA 5-minute protocol are described. Only 65.1% and 25.7% healthy controls and 45.2% and 19.0% patients scored above the conventional cutoff scores of 21/22 and 25/26 on the MoCA. Using classification with norm-derived cutoff scores as reference, locally derived cutoff score of 21/22 yielded a classification discrepancy of ≤42.4%. Discrepancy increased with higher age and lower education level, with the majority being false positives by single cutoffs. With the 25/26 cutoff of the original MoCA, discrepancy further increased to ≤74.3%. CONCLUSIONS: Conventional single cutoff scores are associated with substantially high rates of misclassification especially in older and less-educated patients with stroke. These results caution against the use of one-size-fits-all cutoffs on the MoCA.

RESUMO

BACKGROUND AND PURPOSE: The National Institute of Neurological Disorders and Stroke-Canadian Stroke Network Vascular Cognitive Impairment Harmonization working group proposed a brief cognitive protocol for screening of vascular cognitive impairment. We investigated the validity, reliability, and feasibility of the Montreal Cognitive Assessment 5-minute protocol (MoCA 5-minute protocol) administered over the telephone. METHODS: Four items examining attention, verbal learning and memory, executive functions/language, and orientation were extracted from the MoCA to form the MoCA 5-minute protocol. One hundred four patients with stroke or transient ischemic attack, including 53 with normal cognition (Clinical Dementia Rating, 0) and 51 with cognitive impairment (Clinical Dementia Rating, 0.5 or 1), were administered the MoCA in clinic and a month later, the MoCA 5-minute protocol over the telephone. RESULTS: Administration of the MoCA 5-minute protocol took 5 minutes over the telephone. Total score of the MoCA 5-minute protocol correlated negatively with age (r=-0.36; P<0.001) and positively with years of education (r=0.41; P<0.001) but not with sex (ρ=0.03; P=0.773). Total scores of the MoCA and MoCA 5-minute protocol were highly correlated (r=0.87; P<0.001). The MoCA 5-minute protocol performed equally well as the MoCA in differentiating patients with cognitive impairment from those without (areas under receiver operating characteristics curve for MoCA 5-minute protocol, 0.78; MoCA=0.74; P>0.05 for difference; Cohen d for group difference, 0.80-1.13). It differentiated cognitively impaired patients with executive domain impairment from those without (areas under receiver operating characteristics curve, 0.89; P<0.001; Cohen d=1.7 for group difference). Thirty-day test-retest reliability was excellent (intraclass correlation coefficient, 0.89). CONCLUSIONS: The MoCA 5-minute protocol is a free, valid, and reliable cognitive screen for stroke and transient ischemic attack. It is brief and highly feasible for telephone administration.

RESUMO

OBJECTIVE: Cognitive deficits are common after aneurysmal subarachnoid haemorrhage (aSAH), and clinical evaluation is important for their management. Our hypothesis was that the Montreal Cognitive Assessment (MoCa) is superior to the Mini-Mental State Examination (MMSE) in screening for cognitive domain deficit in aSAH patients. METHODS: We carried out a prospective observational and diagnostic accuracy study on Hong Kong aSAH patients aged 21 to 75 years who had been admitted within 96 hours of ictus. The domain-specific neuropsychological assessment battery, the MoCA and MMSE were administered 2-4 weeks and 1 year after ictus. A cognitive domain deficit was defined as a cognitive domain z score <-1.65 (below the fifth percentile). Cognitive impairment was defined as two or more cognitive domain deficits. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193). RESULTS: Both the MoCA and the MMSE were successful in differentiating between patients with and without cognitive domain deficits and cognitive impairment at both assessment periods. At 1 year post-ictus, the MoCA produced higher area under the curve scores for cognitive impairment than the MMSE (MoCA, 0.92; 95% CI, 0.83 to 0.97 versus MMSE, 0.77; 95% CI, 0.66 to 0.83, p = 0.009). INTERPRETATION: Cognitive domain deficits and cognitive impairment in patients with aSAH can be screened with the MoCA in both the subacute and chronic phases.

RESUMO

UNLABELLED: BACKGROUND AND PRIMARY OBJECTIVE: In recent years, the Montreal Cognitive Assessment (MoCA) has been developed to assess patients with ischemic stroke. However, it has not been validated for use on traumatic brain injury patients with intracranial haemorrhage (tICH). The aim was to evaluate the psychometric properties of the MoCA (MoCA) in such patients. RESEARCH DESIGN AND METHOD: A cross-sectional observational study was carried out on 40 controls and 48 tICH patients recruited in Hong Kong. Concurrent validity was assessed by a comprehensive battery of neuropsychological tests and the Mini-Mental State Examination (MMSE). Criterion validity was assessed by the differentiation of tICH patients from controls. MAIN OUTCOME AND RESULTS: In tICH patients, cognitive z-scores (ß = 0.579; p < 0.001) and MMSE (ß = 0.366, p = 0.012) significantly correlated with performance in the MoCA after adjustment for age, gender and total score for the Geriatric Depressive Scale. For the differentiation of tICH patients from controls, analysis of receiver operating characteristics curves in the MoCA revealed an optimal balance of sensitivity and specificity at 25/26 with an area under the curve of 0.704 (p = 0.001). MoCA is applicable to and significantly correlated with excellent neurological outcomes in tICH patients. CONCLUSIONS: MoCA is a useful and psychometrically valid tool for the assessment of gross cognitive function in tICH patients.

RESUMO

OBJECTIVE: To assess health care providers' perceptions of student pharmacists involved as members of a general medicine team. METHODS: A brief, anonymous, online survey instrument was distributed to 134 health care providers at 4 major medical centers in Massachusetts who interacted with Northeastern University student pharmacists during inpatient general medicine advanced pharmacy practice experiences beginning in March 2011. The survey instrument assessed health care provider perception of student pharmacists' involvement, preparedness, clinical skills, and therapeutic recommendations. RESULTS: Of the 79 providers who responded, 96.2% reported that student pharmacists were prepared for medical rounds and 87.3% reported that student pharmacists were active participants in patient care. Also, 94.9% and 98.7% of providers indicated that student pharmacist recommendations were appropriate and accurate, respectively. The majority (61.8%) of providers believed that student pharmacist involvement on internal medicine teams was beneficial. CONCLUSIONS: Provider perceptions regarding student pharmacist participation on general medicine practice experiences were mostly positive.

RESUMO

OBJECTIVE: Identification of patients with aneurysmal subarachnoid haemorrhage (aSAH) with cognitive impairment is important for patient management (medical treatment, cognitive rehabilitation and social arrangements). The Montreal cognitive assessment (MoCA) is currently recommended over the mini-mental state examination (MMSE) by the U.S. National Institute of Neurological Disorder, in the chronic post-stroke setting. We hypothesised that the MoCA has a better correlation with functional outcome at 3 months than the MMSE. METHODS: We carried out a prospective observational study in Hong Kong over a 2 year period, recruiting patients aged 21-75 years with aSAH admitted within 96 h of ictus. The assessments included the modified Rankin Scale, Lawton Instrumental Activity of Daily Living (IADL), Short Form-36, MoCA and MMSE at 3 months after ictus. Analyses were carried out to compare MoCA with MMSE. RESULTS: 90 patients completed the 3 month assessments. Cognitive impairment (MoCA <26) was determined in 73% of patients at 3 months. Delayed cerebral infarction explained the 31-38% variance in cognitive outcomes (MMSE and MoCA) at 3 months. MoCA demonstrated good discrimination of favourable neurological and IADL outcomes similar to the MMSE in receiver operating characteristics curve analyses. CONCLUSIONS: MoCA defined cognitive impairment was common at 3 months after aSAH and MoCA correlated with functional outcomes similar, but not superior, to the MMSE. The study is registered at ClinicalTrials.gov of the US National Institutes of Health (NCT01038193).

RESUMO

BACKGROUND/AIMS: To evaluate the psychometric properties of the Hong Kong Montreal Cognitive Assessment (HK-MoCA) in patients with cerebral small vessel disease (SVD). METHODS: 40 SVD patients and 40 matched controls were recruited. Concurrent and criterion validity, inter-rater and test-retest reliability, internal consistency of the HK-MoCA were examined and clinical observations were made. RESULTS: Performance on the HK-MoCA was significantly predicted by both executive (beta = 0.23, p = 0.013) and non-executive (beta = 0.64, p < 0.001) composite scores. It differentiated SVD patients from controls (area under the curve = 0.81, p < 0.001) with an optimal cutoff at 21/22. Reliability, internal consistency and clinical utility were good. CONCLUSION: The HK-MoCA is a useful cognitive screening instrument for use in SVD patients.
