Hospital staff education on severe sepsis/septic shock and hospital mortality: an original hypothesis

Background

The Functional Comorbidity Index (FCI) was recently developed to predict physical function in acute lung injury patients using comorbidity data. Our objectives were to determine: (1) the inter-rater reliability of the FCI collected using in-patient discharge summaries (primary objective); and (2) the accuracy and predictive validity of the FCI collected using hospital discharge summaries and admission records versus complete chart review (secondary objectives).

Methods

For reliability, we evaluated the FCI’s intraclass correlation coefficient (ICC) among trained research staff performing data collection for 421 acute lung injury patients enrolled in a prospective cohort study. For validity and accuracy, we compared the detection of FCI comorbidities across three types of inpatient medical records, and the association of the respective FCI scores obtained with patients’ SF-36 physical function subscale (PFS) scores at 1-year follow-up.

Results

Inter-rater reliability was near-perfect (ICC 0.91; 95% CI 0.89-0.94). Hospital admission records and discharge summaries (vs. complete chart review) significantly underestimated the total FCI score. However, using multivariable linear regression, FCI scores collected using each of the three types of inpatient medical records had similar associations with PFS, suggesting similar predictive value.

Conclusions

Data collection using in-patient discharge summaries represents a reliable and valid method for collecting FCI comorbidity information.     

Evaluation of Reliability and Validity of the Hendrich II Fall Risk Model in a Chinese Hospital Population

To translate, validate and examine the reliability and validity of a Chinese version of the Hendrich II Fall risk Model (HFRM) in predicting falls in elderly inpatient. A sample of 989 Chinese elderly inpatients was recruited upon admission at the Peking Union Medical College Hospital. The inpatients were assessed for fall risk using the Chinese version of the HFRM at admission. The reliability of the Chinese version of the HFRM was determined using the internal consistency and test-rested methods. Validity was determined using construct validity and convergent validity. Receiver operating characteristic (ROC) curves were created to determine the sensitivity and specificity. The Chinese version of the HFRM showed excellent repeatability with an intra-class correlation coefficient (ICC) of 0.9950 (95% confidence interval (CI): 0.9923–0.9984). The inter-rater reliability was high with an ICC of 0.9950 (95%CI: 0.9923–0.9984). Cronbach’s alpha coefficient was 0.366. Content validity was excellent, with a content validity ratio of 0.9333. The Chinese version of the HFRM had a sensitivity of 72% and a specificity of 69% when using a cut-off of 5 points on the scale. The area under the curve (AUC) was 0.815 (P<0.001). The Chinese version of the HFRM showed good reliability and validity in assessing the risk of fall in Chinese elderly inpatients.     

Test-retest reliability and construct validity of the ENERGY-parent questionnaire on parenting practices, energy balance-related behaviours and their potential behavioural determinants: the ENERGY-project

ABSTRACT: BACKGROUND: Insight in parental energy balance-related behaviours, their determinants and parenting practices are important to inform childhood obesity prevention. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. The objective of the current study was to examine the test-retest reliability and construct validity of the parent questionnaire used in the ENERGY-project, assessing parental energy balance-related behaviours, their determinants, and parenting practices among parents of 10-12 year old children. FINDINGS: We collected data among parents (n = 316 in the test-retest reliability study; n = 109 in the construct validity study) of 10-12 year-old children in six European countries, i.e. Belgium, Greece, Hungary, the Netherlands, Norway, and Spain. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC) and percentage agreement comparing scores from two measurements, administered one week apart. To assess construct validity, the agreement between questionnaire responses and a subsequent interview was assessed using ICC and percentage agreement. All but one item showed good to excellent test-retest reliability as indicated by ICCs > .60 or percentage agreement [greater than or equal to] 75%. Construct validity appeared to be good to excellent for 92 out of 121 items, as indicated by ICCs > .60 or percentage agreement [greater than or equal to] 75%. From the other 29 items, construct validity was moderate for 24 and poor for 5 items. CONCLUSIONS: The reliability and construct validity of the items of the ENERGY-parent questionnaire on multiple energy balance-related behaviours, their potential determinants, and parenting practices appears to be good. Based on the results of the validity study, we strongly recommend adapting parts of the ENERGY-parent questionnaire if used in future research.     

Development and Validation of the Food-Craving Inventory

Objective: The primary aim of this study was to develop and validate the Food-Craving Inventory (FCI), a self-report measure of specific food cravings. Research Methods and Procedures: In a preliminary study, participants (n = 474) completed the initial version of the FCI. The results from this study were used in developing the revised FCI. Participants (n = 379) completed the revised FCI in the primary study designed to develop a self-report measure of specific food cravings. Results: Common factor analysis yielded four conceptual factors (subscales) that were interpreted as high fats, sweets, carbohydrates/starches, and fast-food fats. Confirmatory factor analysis found that the four factors could be modeled as dimensions (or first-order factors) of a higher order construct—food craving. Test–retest and internal consistency analyses indicated good reliability for the total score and each of the subscales. Subscale scores were compared with scores on the Three Factor Eating Questionnaire and a conceptual measure of food craving. We found support for the content, concurrent, construct, and discriminant validity of the FCI. Discussion: The FCI was found to be a reliable and valid measure of general and specific food cravings. The FCI can be used in research related to overeating and binge eating. Also, it may be useful in treatment studies that target obesity and/or food cravings.     

Obesity and inpatient rehabilitation outcomes following knee arthroplasty: a multicenter study

Objective: This multicenter study examined whether inpatient rehabilitation outcomes following total knee arthroplasty (TKA) were influenced by BMI. Methods and Procedures: This was a retrospective, comparative study conducted using a computerized medical database and medical records derived from TKA patients, at 15 independent rehabilitation hospitals (N = 5,428). Patients were separated into four groups based on BMI: non‐obese (BMI < 25 kg/m²), overweight (25–29.9 kg/m²), moderately obese (30–40 kg/m²), severely obese (BMI ≥ 40 kg/m²). All patients completed an interdisciplinary inpatient rehabilitation program post‐TKA. Total and individual functional independence measure (FIM) scores, length of stay (LOS), FIM efficiency scores, itemized hospital charges, and discharge disposition location, were collected. Results: The percentage of total FIM change was 7.5% greater by the time of discharge in the non‐obese than in the very severely obese (P < 0.05). FIM efficiency was lowest in the severely obese as compared to the remaining groups (3.7 points (pts)/day vs. 4.0–4.3 pts/day; P = 0.044). The change in the motor FIM score from admission to discharge was 6.7–15.6% greater in the non‐obese than in the remaining groups (P < 0.05). The changes in cognition FIM, toilet transfer and walking without assistance scores were higher in the non‐obese as compared to the severely obese group (P < 0.05). The severely obese group had higher total, physical and occupational therapy and pharmacy charges than the remaining groups (P < 0.05). Discussion: An excessive BMI does not prevent gains during inpatient rehabilitation; however, these gains are made less efficiently and at a higher cost than those made when the BMI is low.     

Arabic version of the Geriatric Oral Health Assessment Index

Objectives: The purpose of this study was to translate the original English version of the Geriatric Oral Health Assessment Index (GOHAI) into an Arabic version, and to test the validity and reliability of the translated instrument (GOHAI‐Ar) for use among the elderly in Saudi Arabia. Methods: The 12‐item GOHAI was translated into Arabic using the back‐translation technique and performing a preliminary test to determine the comprehensibility and readability of the Arabic language version. A total of 156 elderly patients answered the questionnaire, and underwent a clinical examination by one calibrated dentist. Information on subjects’ socio‐demographic background and oral health conditions was collected. Convergent validity was evaluated by identifying the associations between perceived oral health status, general health status, perceived need for dental care and GOHAI‐Ar scores. Discriminant validity was examined by comparing the GOHAI‐Ar scores and six oral health parameters. Internal consistency was measured by Cronbach’s alpha. Test–retest reliability was assessed by intra‐class correlation coefficient (ICC) and weighted kappa. Factor structure of GOHAI‐Ar was evaluated using principal component factor analysis. Results: The mean GOHAI‐Ar was 32.1 (SD 12.2; range 11–59). Mean GOHAI‐Ar scores were higher for the elderly who rated their oral and general health as good. Subjects with perceived dental treatment needs had a lower mean GOHAI‐Ar score than those without any such needs. The caries experience, number of missing teeth, OHI‐S score, number of pathologically mobile teeth and number of oral lesions were negatively correlated with the GOHAI‐Ar score. The Cronbach’s alpha (0.93) indicated a high degree of internal consistency and homogeneity between items. The ICC for GOHAI‐Ar was 0.95, the weighted kappa coefficient for individual items varied between 0.42 and 0.71, and the correlation coefficients for the 12 items were above 0.70. Factor analysis didn’t support the expected dimensions of the index, and only one factor was found at eigenvalue greater than 1. Conclusions: The findings suggest an excellent reliability and validity of GOHAI‐Ar. Further research is needed to assess the value of this instrument in oral health‐related quality of life studies in Arabic elderly population.     

Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects

doi: 10.1111/j.1741‐2358.2011.00606.x Reliability and validity of a Japanese version of the Oral Health Impact Profile for edentulous subjects Objective: To evaluate the reliability and validity of the Japanese version of the Oral Health Impact Profile for edentulous (OHIP‐EDENT‐J) patients. Background: Oral Health Impact Profile for edentulous is an appropriate instrument for assessing the Quality of life (QOL) in edentulous patients. However, the reliability and validity of the Japanese version had not been evaluated. Methods: The study was conducted on 116 edentulous patients (Group A, requiring new dentures, n = 61; Group B, already having dentures, n = 55). Cronbach’s alpha (α) was used to measure internal consistency of the summary scores for OHIP‐EDENT‐J and various subscales in Groups A and B. The interclass correlation coefficient (ICC) and 95% confidence interval of the summary scores for OHIP‐EDENT‐J and subscales were calculated. The summary scores for OHIP‐EDENT‐J in Groups A and B were compared with evaluate content validity. The Spearman’s correlation coefficient between the summary scores for OHIP‐EDENT‐J and the satisfaction with dentures (100 mm VAS) was calculated for Groups A and B to evaluate concurrent validity. Results: The reliability of the summary scores for OHIP‐EDENT‐J was good (α = 0.93). The ICC of the summary scores for OHIP‐EDENT‐J was 0.85. Summary scores for OHIP‐EDENT‐J were significantly different (p = 0.027) between Group A and Group B, with Group A having the higher value. The Spearman’s correlation coefficient for the degree of satisfaction with dentures and the summary scores for OHIP‐EDENT‐J, calculated for Groups A and B (n = 107), was ?0.609. Conclusion: The OHIP‐EDENT‐J, a questionnaire on oral health–related QOL comprising 19 items, showed good reliability and validity for edentulous patients.     

Effect of obesity on inpatient rehabilitation outcomes after total hip arthroplasty

Objective: This study examined whether obesity affected inpatient rehabilitation outcomes after total hip arthroplasty (THA). Research Methods and Procedures: This was a retrospective, comparative study conducted using a computerized medical database derived from THA patients at a university‐affiliated rehabilitation hospital (data from 2002 to 2005). Patients were divided into four brackets based on BMI: non‐obese (<25 kg/m²), overweight (25 to 29.9 kg/m²), moderate obesity (30 to 39.9 kg/m²), and severe obesity (≥40 kg/m²). All patients completed an interdisciplinary inpatient rehabilitation program after THA. Functional independence measure (FIM) scores, length of stay (LOS), FIM efficiency scores (FIM/LOS), hospital charges, and discharge disposition location were collected. Results: FIM scores improved from admission to discharge similarly in all groups (25 to 29.5 points). However, FIM efficiency, LOS, and total charges were curvilinearly related with BMI (all p < 0.05). Total hospital charges were highest in the severely obese group compared with the overweight group (p < 0.05). Non‐homebound discharge disposition rates were lower in non‐obese (13.1%) and severely obese groups (10.5%). Discussion: Elevated BMI does not prevent FIM gains in THA patients during inpatient rehabilitation. However, BMI is related with FIM efficiency, LOS, and hospital charges in a curvilinear fashion. Severely obese patients can achieve physical improvements but at a lower efficiency and greater cost.     

The UK Functional Assessment Measure (UK FIM+FAM): Psychometric Evaluation in Patients Undergoing Specialist Rehabilitation following a Stroke from the National UK Clinical Dataset

The UK Functional Assessment Measure (UKFIM+FAM) is the principal outcome measure for the UK Rehabilitation Outcomes Collaborative (UKROC) national database for specialist rehabilitation. Previously validated in a mixed neurorehabilitation cohort, this study is the first to explore its psychometric properties in a stroke population, and compare left and right hemispheric strokes (LHS vs RHS). We analysed in-patient episode data from 62 specialist rehabilitation units collated through the UKROC database 2010–2013. Complete data were analysed for 1,539 stroke patients (LHS: 588, RHS: 566 with clear localisation). For factor analysis, admission and discharge data were pooled and randomised into two equivalent samples; the first for exploratory factor analysis (EFA) using principal components analysis, and the second for confirmatory factor analysis (CFA). Responsiveness for each subject (change from admission to discharge) was examined using paired t-tests and differences between LHS and RHS for the entire group were examined using non-paired t-tests. EFA showed a strong general factor accounting for >48% of the total variance. A three-factor solution comprising motor, communication and psychosocial subscales, accounting for >69% total variance, provided acceptable fit statistics on CFA (Root Mean Square Error of Approximation was 0.08 and Comparative Fit Index/ Tucker Lewis Index 0.922/0.907). All three subscales showed significant improvement between admission and discharge (p<0.001) with moderate effect sizes (>0.5). Total scores between LHS and RHS were not significantly different. However, LHS showed significantly higher motor scores (Mean 5.7, 95%CI 2.7, 8.6 p<0.001), while LHS had significantly lower cognitive scores, primarily in the communication domain (-6.8 95%CI -7.7, -5.8 p<0.001). To conclude, the UK FIM+FAM has a three-factor structure in stroke, similar to the general neurorehabilitation population. It is responsive to change during in-patient rehabilitation, and distinguishes between LHS and RHS. This tool extends stroke outcome measurement beyond physical disability to include cognitive, communication and psychosocial function.     

The reliability and reproducibility of foot type measurements using a mirrored foot photo box and digital photography compared to caliper measurements

The height of the medial longitudinal arch (MLA) is thought to be a predisposing factor to various lower extremity injuries. Discrepancy exists as to whether MLA height plays a role in injury prevention. The purpose of this study was to determine the intertester and intratester reliability, and the validity of the mirrored foot photo box (MFPB) and caliper measurements to radiographic measurements. METHODS: Thirty subjects with equal numbers of men and women were recruited. Both feet were tested (n=60) in a 90% weight bearing stance. A set of anatomic landmarks were palpated, marked, and measured using a caliper, MFPB, and radiographs. The protocol was completed by two testers on 2 days approximately 1 week apart. Intertester and intratester reliability were determined using the intraclass correlation coefficient (ICC)(2,k) and the ICC(2,1), respectively. Validity of both measurement techniques to radiographic measurements was determined using the ICC(2,k). RESULTS: The intertester reliability ranged from 0.991 to 0.577, while the intratester reliability ranged from 0.994 to 0.527, with first metatarsal angle being the only variable with poor reliability. Most variables demonstrated acceptable validity between the MFPB and the caliper measurements, and acceptable validity between the MFPB and calipers compared to radiographic measurements. The MFPB took 51.3+/-19.6s per foot while the caliper measurements averaged 227.4+/-68.9s to complete the measurements. DISCUSSION: The MFPB is as reliable as the caliper measurements, and offers better intertester reliability. Both the caliper and MFPB measurements demonstrated acceptable validity to radiographic measurements and testing time was reduced when using the MFPB compared to calipers.     

Psychiatric discharge summaries: what do general practitioners want?

Aims As part of an initiative to improve and standardise our discharge summaries, we investigated the preferences of general practitioners (GPs) with regards to the information provided in summaries.Method Our study methods included sending a questionnaire to all GPs in our area gathering their views on what information to include in discharge summaries on first and on subsequent inpatient episodes.Results The response rate was 68%. Most GPs wanted a comprehensive first discharge summary, particularly stressing the importance of practical information. Subsequent discharge summaries could exclude case histories.Clinical implications Contrary to previous studies indicating a demand for brief reports, this survey indicates that the GPs surveyed value considerable detail in adult psychiatry discharge summaries. It is important to include these views in setting standards for the auditing process and before implementing changes.     

Reliability and validity of the performance index evaluation among men's and women's college basketball players

The Performance Index Evaluation (PIE) is a basketball-specific assessment of physical performance. The battery consists of items typically included in sport assessments, such as agility and power, but also addresses an often-overlooked performance component, namely, core strength. The purpose of this study was to examine the reliability (test-retest, interrater), validity (criterion-related, construct-related), and practice effect of the PIE among men's and women's college basketball players. Test-retest estimates were moderate for men (intraclass correlation coefficient [ICC] = 0.79) and poor for women (ICC = 0.35), but interrater reliability was high (ICC = 0.95). Criterion-related validity evidence (i.e., relationship between PIE and playing time) was weak, but construct-related evidence was acceptable (i.e., college players had higher scores than high school players). A practice effect was also demonstrated among men. In conclusion, reliability of the battery should be improved before its use is recommended among college basketball players. Additionally, the battery does not appear to be a predictor of performance but does appear to distinguish between skill levels.     

Geriatric conditions in acutely hospitalized older patients: prevalence and one-year survival and functional decline

Background

To study the prevalence of eighteen geriatric conditions in older patients at admission, their reporting rate in discharge summaries and the impact of these conditions on mortality and functional decline one year after admission.

Method

A prospective multicenter cohort study conducted between 2006 and 2008 in two tertiary university teaching hospitals and one regional teaching hospital in the Netherlands. Patients of 65 years and older, acutely admitted and hospitalized for at least 48 hours, were invited to participate. Eighteen geriatric conditions were assessed at hospital admission, and outcomes (mortality, functional decline) were assessed one year after admission.

Results

639 patients were included, with a mean age of 78 years. IADL impairment (83%), polypharmacy (61%), mobility difficulty (59%), high levels of primary caregiver burden (53%), and malnutrition (52%) were most prevalent. Except for polypharmacy and cognitive impairment, the reporting rate of the geriatric conditions in discharge summaries was less than 50%. One year after admission, 35% had died and 33% suffered from functional decline. A high Charlson comorbidity index score, presence of malnutrition, high fall risk, presence of delirium and premorbid IADL impairment were associated with mortality and overall poor outcome (mortality or functional decline). Obesity lowered the risk for mortality.

Conclusion

Geriatric conditions were highly prevalent and associated with poor health outcomes after admission. Early recognition of these conditions in acutely hospitalized older patients and improving the handover to the general practitioner could lead to better health outcomes and reduce the burden of hospital admission for older patients.     

The Synergistic Effect of Functional Status and Comorbidity Burden on Mortality: A 16-Year Survival Analysis

Objectives

The relationship between disability and comorbidity on mortality is widely perceived as additive in clinical models of frailty.

Design

National data were retrospectively extracted from medical records of community hospital.

Data Sources

There were of 12,804 acutely-disabled patients admitted for inpatient rehabilitation in Singapore rehabilitation community hospitals from 1996 through 2005 were followed up for death till 31 December 2011.

Outcome Measure

Cox proportional-hazards regression to assess the interaction of comorbidity and disability at discharge on all-cause mortality.

Results

During a median follow-up of 10.9 years, there were 8,565 deaths (66.9%). The mean age was 73.0 (standard deviation: 11.5) years. Independent risk factors of mortality were higher comorbidity (p<0.001), severity of disability at discharge (p<0.001), being widowed (adjusted hazard ratio [aHR]: 1.38, 95% confidence interval [CI]:1.25–1.53), low socioeconomic status (aHR:1.40, 95%CI:1.29–1.53), discharge to nursing home (aHR:1.14, 95%CI:1.05–1.22) and re-admission into acute care (aHR:1.54, 95%CI:1.45–1.65). In the main effects model, those with high comorbidity had an aHR = 2.41 (95%CI:2.13–2.72) whereas those with total disability had an aHR = 2.28 (95%CI:2.12–2.46). In the interaction model, synergistic interaction existed between comorbidity and disability (p<0.001) where those with high comorbidity and total disability had much higher aHR = 6.57 (95%CI:5.15–8.37).

Conclusions

Patients with greater comorbidity and disability at discharge, discharge to nursing home or re-admission into acute care, lower socioeconomic status and being widowed had higher mortality risk. Our results identified predictive variables of mortality that map well onto the frailty cascade model. Increasing comorbidity and disability interacted synergistically to increase mortality risk.     

The validity and reliability of the 1RM bench press using chain-loaded resistance

The purposes of this study were to determine the validity and test-retest reliability of the 1 repetition maximum (1RM) chain-loaded, free-weight bench press (CBP) and to examine possible learning effects that may occur between the test-retest measurements. Nine resistance-trained men (20.58 +/- 1.31 years, 188.24 +/- 9.29 cm, 92.07 +/- 16.94 kg) and seven resistance-trained women (20.42 +/- 0.98 years, 175.61 +/- 9.32 cm, 73.61 +/- 10.80 kg) participating in Division II college basketball completed this study. Two familiarization sessions took place using light to moderate loads to learn proper technique. The subjects completed a 1RM test on the traditional plate-loaded bench press 4 days before completion of the CBP 1RM, which was followed by 4 days of rest before completing the retest. Intraclass correlation coefficients (ICC) and the percent coefficients of variation (CV) were used to determine relative and absolute test-retest reliability. Concurrent validity was determined from the Pearson correlation coefficients between the CBP and the plate-loaded bench press. Test-retest differences were analyzed with the paired t-test. ICC and CV for the men (r = 0.99, 1.4%) and women (r = 0.93, 3.5%), respectively indicate that highly reproducible 1RM scores can be found with the CBP. High validity was also found with high correlations between the CBP and plate-loaded bench press for the men (r = 0.95) and women (r = 0.80). A statistically significant (p = 0.04) but clinically small (2.57 kg) shift in the mean occurred between the CBP test and retest for the men, whereas no change occurred for the women. The data indicate that valid and reliable 1RM scores can be found after two familiarization sessions in men and women athletes who have previous resistance training experience.     

Reliability and Validity of the Chinese Version Appropriateness Evaluation Protocol

Objective

To adapt the Appropriateness Evaluation Protocol (AEP) to the specific settings of health care in China and to validate the Chinese version AEP (C-AEP).

Methods

Forward and backward translations were carried out to the original criteria. Twenty experts participated in the consultancy to form a preliminary version of the C-AEP. To ensure applicability, tests of reliability and validity were performed on 350 admissions and 3,226 hospital days of acute myocardial infraction patients and total hip replacement patients in two tertiary hospitals by two C-AEP reviewers and two physician reviewers. Overall agreement, specific agreement, and Cohen’s Kappa were calculated to compare the concordance of decisions between pairs of reviewers to test inter-rater reliability and convergent validity. The use of “overrides” and opinions of experts were recorded as measurements of content validity. Face validity was tested through collecting perspectives of nonprofessionals. Sensitivity, specificity, and predictive values were also reported.

Results

There are 14 admission and 24 days of care criteria in the initial version of C-AEP. Kappa coefficients indicate substantial agreement between reviewers: with regard to inter-rater reliability, Kappa (κ) coefficients are 0.746 (95% confidence interval [CI] 0.644–0.834) and 0.743 (95% CI 0.698–0.767) of admission and hospital days, respectively; for convergent validity, the κ statistics are 0.678 (95% CI 0.567–0.778) and 0.691 (95% CI 0.644–0.717), respectively. Overrides account for less than 2% of all judgments. Content validity and face validity were confirmed by experts and nonprofessionals, respectively. According to the C-AEP reviewers, 18.3% of admissions and 28.5% of inpatient days were deemed inappropriate.

Conclusions

The C-AEP is a reliable and valid screening tool in China’s tertiary hospitals. The prevalence of inappropriateness is substantial in our research. To reduce inappropriate utilization, further investigation is needed to elucidate the reasons and risk factors for this inappropriateness.     

External quality control for immunocytochemistry on cytology samples: a review of UK NEQAS ICC (cytology module) results

I. S. Kirbis, P. Maxwell, M. S. Fle?ar, K. Miller and M. Ibrahim External quality control for immunocytochemistry on cytology samples: a review of UK NEQAS ICC (cytology module) results Objective: To date, external quality control for immunocytochemistry on cytology samples is provided only by the United Kingdom national external quality assessment service for immunocytochemistry and in situ hybridisation (UK NEQAS ICC & ISH). For the purpose of this study a retrospective analysis of a comprehensive collection of quality‐related data regarding immunocytochemistry on cytology samples collected through this service was analysed. Methods: The quality of immunocytochemical reactions, using on‐line collected data, was analysed for the last 23 UK NEQAS ICC cytology module external quality assessments carried out on cytology samples completed in the period from 2004 to 2010. Results: Our study showed that the majority of participants in the cytology module (66%) sent formalin‐fixed paraffin‐embedded (FFPE) tissue sections for assessment as in‐house control slides and only 34% sent cytology slides of various types. The highest UK NEQAS ICC score for the quality of immunocytochemical staining among in‐house control slides was achieved on cell block sections, followed by cytospins, FFPE tissue sections, liquid‐based cytology slides and smears. With regard to fixation, acetone‐fixed slides achieved significantly lower scores than other reported fixatives. The strength of agreement in perception of immunocytochemical staining quality was good between in‐house assessors (Kappa = 0.64) but only fair between in‐house and UK NEQAS ICC assessors (Kappa = 0.22). Conclusions: Good quality of immunocytochemical staining can be achieved on cytology slides prepared and fixed in different ways as well as on cell blocks. Unified criteria for high‐quality immunocytochemical staining and proper internal and external quality assurance could facilitate further improvement and standardization of immunocytochemistry on cytology samples.     

Sentiment Measured in Hospital Discharge Notes Is Associated with Readmission and Mortality Risk: An Electronic Health Record Study

Natural language processing tools allow the characterization of sentiment–that is, terms expressing positive and negative emotion–in text. Applying such tools to electronic health records may provide insight into meaningful patient or clinician features not captured in coded data alone. We performed sentiment analysis on 2,484 hospital discharge notes for 2,010 individuals from a psychiatric inpatient unit, as well as 20,859 hospital discharges for 15,011 individuals from general medical units, in a large New England health system between January 2011 and 2014. The primary measures of sentiment captured intensity of subjective positive or negative sentiment expressed in the discharge notes. Mean scores were contrasted between sociodemographic and clinical groups in mixed effects regression models. Discharge note sentiment was then examined for association with risk for readmission in Cox regression models. Discharge notes for individuals with greater medical comorbidity were modestly but significantly lower in positive sentiment among both psychiatric and general medical cohorts (p<0.001 in each). Greater positive sentiment at discharge was associated with significantly decreased risk of hospital readmission in each cohort (~12% decrease per standard deviation above the mean). Automated characterization of discharge notes in terms of sentiment identifies differences between sociodemographic groups, as well as in clinical outcomes, and is not explained by differences in diagnosis. Clinician sentiment merits investigation to understand why and how it reflects or impacts outcomes.     

ISAR Score (Identification of Seniors At Risk) predice la mortalidad en mayores de 75 años ingresados en Cuidados Intensivos

Background and objectivesCurrently, the patient's baseline situation is a more important prognostic factor than age. The purpose of this study is to estimate the prognostic value of the ISAR score (Identification of Senior at Risk) in patients ≥75 years admitted to intensive care (ICU).Patients and methodsProspective multicenter study including patients ≥75 years admitted to the ICU > 24 hours. On admission, 28 days and 6 months after discharge from the ICU, mortality and baseline were evaluated using the ISAR score, the Lawton and Brody scale (LB) and the Barthel index (BI), the Frail fragility scale. scale (FS), the Charlson comorbidity index (ICC), Dementia rating score (DRC).Results38 of 94 patients (40%) were high risk (ISAR ≥ 3) and were characterized by BI 90 (65-100), LB 4 (3-5), and CDR 1 (0-2), ICC 7.5 (6-10). 58% had FS ≥ 3. In the long term, they were in a situation of dependency [BI 50 (2.5-77.5), LB 3 (0-4), CDR 1 (0-1.5)]. The ICU mortality at 28 days and 6 months was 18.4%, 25.7% and 35.3%, respectively, being statistically significant. The area under the ISAR score ROC curve was 0.749 to 0.797, in all the mortality periods studied, although the difference with other predictive variables was not significant, but the p value was the lowest.ConclusionsThe ISAR score predicts mortality in critically elderly patients with a discriminative capacity comparable to other predictive variables.
