Predicting sequelae and death after bacterial meningitis in childhood: A systematic review of prognostic studies

Background  

Bacterial meningitis (BM) is a severe infection responsible for high mortality and disabling sequelae. Early identification of patients at high risk of these outcomes is necessary to prevent their occurrence by adequate treatment as much as possible. For this reason, several prognostic models have been developed. The objective of this study is to summarize the evidence regarding prognostic factors predicting death or sequelae due to BM in children 0-18 years of age.     

Sleep and Sleep Disturbance in Children: Reliability and Validity of the Dutch Version of the Child Sleep Habits Questionnaire

Study Objectives:

The Child Sleep Habits Questionnaire (CSHQ) was developed in the US for measuring medical and behavioral sleep disorders in school-aged children. This study was conducted to assess the reliability and structural validity of the Dutch version of the CSHQ.

Design:

Population-based study

Setting:

Questionnaires (n = 2385) were distributed to children in primary schools and daycare centers to be completed by the parent/guardian. An identical second questionnaire was distributed for test-retest and interobserver reliability, which were assessed using intraclass correlation, and compared with published data. Internal consistency was assessed by Cronbach α (per subscale). Validity was analyzed by confirmatory and exploratory factor analysis.

Participants:

School-aged children.

Interventions:

None.

Measurements & Results:

The questionnaire was returned by 1502 (63%) parents, 47% returned the questionnaire for test-retest, and 32% for interobserver reliability. Test-retest reliability was moderate to good, ranging from 0.47 to 0.93. Interobserver reliability was moderate to good, ranging from 0.53 to 0.87, with the exception of Sleep duration. Cronbach α ranged from 0.47 to 0.68. In confirmatory factor analysis the domain structure of the original American CSHQ could not be confirmed. Exploratory factor analysis suggested a 4-factor structure rather than the original 8 domains.

Conclusions:

The CSHQ seems to have an adequate reliability and moderate internal consistency in a Dutch population with different sociocultural characteristics than the US population in which it was devised. Factor analysis suggests that translation, cultural background, or subscales of the original instrument may affect the performance of the CSHQ.

The course and prognosis of hip complaints in general practice

Background: The general practitioner needs to discriminate complaints with need of specialist care from those that can be managed in primary care. However, no previous research has studied prognostic indicators for the course of hip complaints in a primary care population.Purpose: The purpose of this study was to investigate the course of hip complaints presented in general practice and to identify relevant prognostic indicators of outcome.Methods: Data were collected by means of self-administered questionnaires containing questions about sociodemographic variables, characteristics of the complaints, and several intraindividual and extraindividual factors, including several psychosocial variables (e.g., pain coping, distress, and kinesiophobia). After 3 and 12 months of follow-up perceived recovery, change in pain intensity and change in functioning were assessed. Multiple regression analyses were performed to investigate the association between the potential prognostic indicators and the 3 outcome measures.Results: We included 139 patients with hip complaints, presented in general practice. Only 24% reported recovery after 3 months, increasing to 37% after 12 months. A history of hip complaints, a longer duration of the current episode of hip complaints, or more severe complaints, were associated with a less favorable prognosis. Furthermore, more vital patients and patients who met the Norm for Healthy Activity had a higher probability of a favorable outcome. Pain transformation and worrying were significant associated with recovery and changes in functioning after 3 months.Conclusions: Different prognostic indicators were found to be associated with perceived recovery, changes in pain intensity, and changes in functioning. Future research should aim at investigating the mechanisms that can underlie these associations. This study was financially supported by the Dutch Arthritis Association.     

Psychometric properties of the Dutch-Flemish Patient-Reported Outcomes Measurement Information System Pain Behavior item bank in patients with musculoskeletal complaints

We studied the psychometric properties of the 39-item v1.1 Dutch-Flemish Patient-Reported Outcomes Measurement Information System Pain Behavior item bank in a sample of 1,602 patients with musculoskeletal complaints. We evaluated the assumptions of the underlying item response theory (IRT) model (unidimensionality and local dependency with confirmatory factor analyses), and monotonicity with scalability coefficients). We studied the IRT model fit of all items and estimated the item parameters of the IRT model. Differential item functioning (DIF) was studied for age and gender, and DIF for language was studied as a measure of cross-cultural validity. Confirmatory factor analyses showed suboptimal fit of a unidimensional model, but a bifactor model showed low risk of bias when a unidimensional model was assumed (Omega H = .92, explained common variance of .70). Fifteen item pairs (2%) were locally dependent. Five items showed poor scalability. All items fitted the IRT model; slope parameters ranged from .60 to 2.00, and threshold parameters from –2.05 to 6.80. One item showed DIF for age, 1 item DIF for gender, and 5 items showed DIF for language, but the impact on total scores was low. Our study shows limitations of the Dutch-Flemish Patient-Reported Outcomes Measurement Information System Pain Behavior item bank when used in a primary care population with musculoskeletal complaints.PerspectiveWe studied the psychometric properties of the Dutch-Flemish Patient-Reported Outcomes Measurement Information System Pain Behavior item bank in a large primary care population of patients with musculoskeletal complaints. It showed that the Pain Behavior item bank has limitations when used in this population.     

Determinants of heart failure self-care: a systematic literature review

Self-care is an important aspect of heart failure (HF) management. Information on the determinants of self-care is necessary for the development of self-care promotion interventions. HF self-care includes self-care management, self-care maintenance, sodium, fluid and alcohol intake restriction, physical activity, smoking cessation, monitoring signs and symptoms and keeping follow-up appointments. To assess the evidence regarding presumed determinants of HF self-care and make recommendations for interventions to promote self-care behavior among HF patients, a systematic literature review was conducted. Based on inclusion and exclusion criteria and a quality assessment, twenty-six articles were included. A best evidence synthesis was used. Results showed that the length of time since patients’ diagnosis with HF is positively related to their performance of self-care maintenance. Moreover, it was found that HF patients’ perceived benefits and barriers are related to their restriction of sodium intake, and that patients with type-D personality are less likely to consult medical professionals. There was also evidence for a few non-significant relationships. All other evidence was inconsistent, mainly due to insufficient evidence. Interventions that aim to increase the performance of self-care maintenance can teach newly diagnosed patients the skills that are usually attained with experience acquired as a result of living with HF for a longer time. Perceived benefits and barriers of restricting sodium intake could be targeted in interventions for sodium intake reduction among HF patients. Finally, interventions for the promotion of adequate consulting of medical professionals can specifically target HF patients with a type-D personality.
