A note on the parameter set for factor analysis models

AbstractNecessary and sufficient conditions are given for the compactness of the parameter set of models for factor analysis together with implications for purposes of estimation

Outcome calculations based on nursing documentation in the first generation of electronic health records in the Netherlands

OBJECTIVES: Previous studies regarding nursing documentation focused primarily on documentation quality, for instance, in terms of the accuracy of the documentation. The combination between accuracy measurements and the quality and frequencies of outcome variables such as the length of the hospital stay were only minimally addressed. METHOD: An audit of 300 randomly selected digital nursing records of patients (age of >70 years) admitted between 2013-2014 for hip surgery in two orthopaedic wards of a general Dutch hospital was conducted. RESULTS: Nursing diagnoses: Impaired tissue perfusion (wound), Pressure ulcer, and Deficient fluid volume had significant influence on the length of the hospital stay. CONCLUSION: Nursing process documentation can be used for outcome calculations. Nevertheless, in the first generation of electronic health records, nursing diagnoses were not documented in a standardized manner (First generation 2010-2015; the first generation of electronic records implemented in clinical practice in the Netherlands)

Nurses' perceptions in caring for people with dementia in Dutch acute hospitals

AIMS AND OBJECTIVES: Overall, this study aimed to describe nursing care for patients with dementia in acute hospitals, with the objectives of describing the provided nursing care (a), nurses’ attitudes and perceptions in caring for patients with dementia (b), and exploring how nurses deal with challenging behaviour (c). Additionally, we determined background variables associated with caring for people with dementia. BACKGROUND: Due to comorbidities, people with dementia are frequently admitted to acute care hospitals. Here, they are at high risk of complications. Nurses strive for good care but regularly experience insufficient knowledge and skills regarding caring for people with dementia. DESIGN: A cross‐sectional survey study design. METHODS: Data were collected in seven Dutch acute hospitals and through social media. In total, 229 hospital nurses completed the questionnaire. We used the Geriatric In‐Hospital Nursing Care Questionnaire and two subscales of Hynninen on managing challenging behaviour. This report followed the STROBE checklist. RESULTS: Nurses express that they often apply general preventive interventions not explicitly related to dementia care. In general, nurses have mixed feelings about the nursing care provided in their department. For challenging behaviour, a variety of approaches, including restrictive measures and medication, is applied. The nurses’ attitudes and perceptions are influenced by the type of hospital where the nurses work, the level of education, the number of hours nurses work, and if the nurses completed a course on dementia in the last year. CONCLUSIONS: Despite a positive attitude, nurses do not have the specific knowledge and skills needed to provide proper care. Nurses who recently completed a course on dementia had more positive attitudes and perceptions towards caring for patients with dementia. RELEVANCE TO CLINICAL PRACTICE: The results of this research can be used to improve the quality of nursing care for patients with dementia in acute hospitals

Reference values for isometric muscle force among workers for the Netherlands: a comparison of reference values

BACKGROUND: Muscle force is important for daily life and sports and can be measured with a handheld dynamometer. Reference values are employed to quantify a subject's muscle force. It is not unambiguous whether reference values can be generalized to other populations. Objectives in this study were; first to confirm the reliability of the utilization of hand-held dynamometers for isometric strength measurement; second to determine reference values for a population of Dutch workers; third to compare these values with those of a USA population. METHODS: 462 Healthy working subjects (259 male, 203 female) were included in this study. Their age ranged from 20 to 60 years with a mean (sd) of 41 (11) years. Muscle force values from elbow flexion and extension, knee flexion and extension, and shoulder abduction were measured with the break method using a MicroFet 2 hand-held dynamometer. Reliability was analyzed by calculating ICC's and limits of agreement. Muscle force expressed in Newton, means, and confidence intervals were determined for males and females in age groups ranging from twenty to sixty years old. Regression equations and explained variances were calculated from weight, height, age, and gender. The mean values and 95% CI were compared to the results from other studies. RESULTS: Reliability was good; the ICC ranged between 0.83 to 0.94. The explained variance ranged from 0.25 to 0.51. Comparison of data for the Dutch population mean muscle force values with those from the USA revealed important differences between muscle force reference values for the American and Dutch populations. CONCLUSIONS: Muscle force measurements demonstrate a sound reliability. Reference values and regressions equations are made available for the Dutch population. Comparison with other studies indicates that reference values differ between countries

The development and psychometric evaluation of an interprofessional identity measure:extended Professional Identity Scale (EPIS)

The purpose of this study was to develop and evaluate an interprofessional identity measurement instrument based on Extended Professional Identity Theory (EPIT). The latter states that interprofessional identity is a social identity superordinate to a professional identity consisting of three interrelated interprofessional identity characteristics: belonging, commitment and beliefs. Scale development was based on five stages: 1) construct clarification, 2) item pool generation, 3) review of initial item pool, 4) shortening scale length (EFA to determine top four highest factor loadings per subscale; 97 dental and dental hygiene students), and 5) cross-validation and construct validity confirmation (CFA; 152 students and 48 teachers from six curricula). Explained variance of the EPIS was 65%. Internal consistency of the subscales was 0.79, 0.81 and 0.80 respectively and 0.89 of the overall scale. CFA confirmed three-dimensionality as theorized by EPIT. Several goodness-of-fit indexes showed positive results: CFI = 0.968 > 0.90, RMSEA = 0.039 < 0.05, and SRMR = 0.056 ≤ 0.08. The factor loadings of the CFA ranged from 0.58 to 0.80 and factors were interrelated. The Extended Professional Identity Scale (EPIS) is a 12-item measurement instrument with high explained variance, high internal consistency and high construct validity with strong evidence for three-dimensionality
