The opportunity costs of caring for people with dementia in Southern Spain

Objective

The aim of this paper is to study the opportunity costs (OC) that are involved in being a caregiver and to compare them with the direct costs assumed by the State and the families. We evaluate direct cost (those that imply a payment-out-of-pocket) and indirect cost (those that imply a dedication in time). We hypothesized that costs increase with the severity of the dementia, with the educational level and active occupational situation of caregiver. They are greater if the caregiver is male, but if the patient and caregiver cohabit they are reduced.

Cost of postoperative complications: How to avoid calculation errors

Postoperative complications(PC) are a basic health outcome, but no surgery service in the world records and/or audits the PC associated with all the surgical procedures it performs. Most studies that have assessed the cost of PC suffer from poor quality and a lack of transparency and consistency. The payment system in place often rewards the volume of services provided rather than the quality of patients' clinical outcomes. Without a thorough registration of PC, the economic costs involved cannot be determined. An accurate, reliable appraisal would help identify areas for investment in order to reduce the incidence of PC,improve surgical results, and bring down the economic costs. This article describes how to quantify and classify PC using the Clavien-Dindo classification and the comprehensive complication index, discusses the perspectives from which economic evaluations are performed and the minimum postoperative follow-up established, and makes various recommendations. The availability of accurate and impartially audited data on PC will help reduce their incidence and bring down costs. Patients, the health authorities, and society as a whole are sure to benefit.     

Movement related potentials in acutely induced weakness and stroke

Weakness is a common symptom of neurological illness, and recovery may occur via restorative or compensatory mechanisms. Functional imaging studies have shown varied patterns of activity in motor areas following recovery from stroke. Movement related potentials (MRP) reflect the activity in primary and non-primary motor areas. We recorded MRPs in association with index finger abduction in six normal volunteers before and after induced weakness of a hand muscle and in six stroke patients with subcortical lesions and weakness affecting the arm. In both groups of subjects the greatest change was observed in the motor potential component of the MRP. On average, the motor potential had its greatest amplitude and duration at the time of the greatest weakness and became smaller with recovery. In artificially-induced weakness, the MRP had an earlier onset latency (P=0.042) and a greater early BP component (P=0.05) for the weakened finger. For the stroke subjects overall, the peak and NS amplitudes were largest for the initial study and declined thereafter. Similar but smaller changes were present for movements of the clinically unaffected side. The increased motor potential is therefore consistent with increased activity in the motor cortex, and this may occur as compensation for weakness in both normals and after stroke.     

Skeletal muscle involvement in infantile systemic hyalinosis

Infantile Systemic Hyalinosis is a rare autosomal recessive entity, characterised by deposition of hyaline material in skin and bone, often complicated by visceral involvement. The characteristic features are marked delay in motor milestones attributed to severe progressive flexion contractures of proximal and distal joints, and skin and mucosal hypertrophy and thickening, followed by failure to thrive. Pain secondary to osteolytic lesions is also a predominant feature. We report a patient with Infantile Systemic Hyalinosis, confirmed by the clinical findings, who also displayed clear evidence of proximal muscle weakness. Muscle biopsy revealed myopathic changes, which have not been reported previously. We suggest that skeletal muscle is involved in Infantile Systemic Hyalinosis and contributes to the characteristic poor outcome of these patients.

Externalizing and internalizing behavioural problems related to asthma in school children

We investigated the relationships of behavioural problems as assessed using the standardized Strengths and Difficulties Questionnaire (SDQ) to asthma in view of improving asthma management. Six thousand eight hundred and eighty children (mean age 10.4 years, male: 49%) were recruited in the French 6 Cities Study. Children with abnormal or borderline emotional symptoms (internalizing problems) or conduct problems (externalizing problems) were more asthmatic than others (P < 0.01). Compared to being normal, abnormal emotional symptoms or conduct problems were found to be related to mild‐to‐moderate persistent asthma (logistic model adjusted odds ratio = 1.55 (95% CI = 1.26–1.90) and 1.42 (95% CI = 1.17–1.71), respectively) and to early‐onset asthma (Cox's model Adjusted Hazard Risk = 1.60 (95% CI = 1.27–2.01) and 1.34 (95% CI = 1.05–1.70). Borderline conduct problems were found to be negatively related to parents' knowledge on how to prevent asthma attacks, compared to normal conduct problems [adjusted OR = 0.51 (95% CI = 0.31–0.85)]. Further data are needed to better understand the involvement of behavioural problems in childhood asthma according to phenotypes.     

Care and treatments related to intensive care unit–acquired muscle weakness: A cohort study

BackgroundIntensive care unit–acquired muscle weakness (ICUAW) has an incidence of 40–46%. Early mobilisation is known to be a protective factor.ObjectiveThe aim of the study was to identify the incidence of ICUAW in Spain and to evaluate variables likely to contribute to the development of ICUAW.MethodsA 4-month, prospective observational multicentre cohort study was conducted on patients receiving invasive mechanical ventilation for at least 48 h. Data were collected from ICU day 3 until ICU discharge. The primary outcome was presence of ICUAW (diagnosed using the Medical Research Council [MRC] scale). The secondary outcome was nurse–patient ratio, physiotherapist availability, analgesia, sedation and delirium management, glycaemic control, and daily level of mobility during the ICU stay as per the ICU Mobility Scale. A logistic regression model was constructed based exclusively on days 3–5 of the ICU stay.ResultsThe data of 642 patients were analysed from 80 ICUs, accounting for 35% of all ICUs in Spain. The incidence of ICUAW was 58% (275 of 474 patients; 95% confidence interval [CI] [53–62]). The predictors for ICUAW were older age (odds ratio [OR] = 1.01; 95% CI [1.00–1.03]) and more days with renal replacement therapy (OR = 1.01; 95% CI [1.00–1.02]). The protective factors for ICUAW were male gender (OR = 0.58; 95% CI [0.38–0.89]), higher Barthel Index (showing prehospital functional independence) (OR = 0.97; 95% CI [0.95–0.99]), more days of being awake and cooperative (defined by a feasible MRC assessment) (OR = 0.98; 95% CI [0.97–0.99]), presence of delirium (OR = 0.98; 95% CI [0.97–0.99]), and more days with active mobilisation (ICU Mobility Scale ≥ 4) (OR = 0.98; 95% CI [0.97–0.99]).ConclusionsThe risk factors for ICUAW were functional dependence before admission, female gender, older age, and more days on renal replacement therapy. The protective factors for ICUAW were feasibility of MRC assessment, the presence of delirium, and being actively mobilised during the first 5 days in the ICU.     

Psychometric Properties of the Self-Report Version of the Strengths and Difficulties Questionnaire in Korea

Objective

To examine the reliability and validity of the self-report Korean version of Strengths and Difficulties Questionnaire (SDQ-Kr) in the community sample.

Methods

The SDQ-Kr was administered to a large sample of school children and adolescents (n=2814) and youth attendees of a psychiatric clinic (n=385) aged 11-16 years. To examine temporal stability, the same questionnaire was administered to a subsample of 167 school youths five to six weeks after the initial assessment. To examine the reliability, we calculated Cronbach''s alpha coefficients for internal consistency and Pearson''s correlations for test-retest stability. In order to evaluate the factorial structure of the SDQ-Kr items, we conducted an exploratory factor analysis (EFA) with varimax rotation. Finally, discriminant validity was examined by using receiver operating characteristic (ROC) curves employing the area under the curve (AUC) as an index of discriminant ability.

Results

Although the internal consistency of some subscales of the SDQ-Kr was somewhat less satisfactory (alpha coefficients; 0.28-0.54) than the English original, coefficients for the total difficulties scores approached sufficient levels (coefficients; 0.69). Other psychometric properties including discriminant validity (AUC for total difficulties and four subscales >0.7) were comparable to those obtained in other language studies.

Conclusion

The self-report SDQ-Kr exhibited a low level of reliability, indicating that some items need to be further evaluated and revised to improve the psychometric properties. We suggest that the total difficulties score could be used with more confidence for screening possible mental health problems in youths.
