Morbilidad psíquica, existencia de diagnóstico y consumo de psicofármacos. Diferencias por comunidades autónomas según la Encuesta Nacional de Salud de 2006

Background: Most of the studies on sychological distress in Spain have been conducted in small geographical areas or specific population groups. However, there are no studies that provide representative data for each Autonomous Community (AC). The objectives of this paper are to determine, both in Spain and in the AC, the prevalence of psychological distress, diagnosis, use of psychoactive medication, social support and self-perceived health, as well as to study the association between psychological distress and the rest of the variables. Methods: Cross-sectional study, using data from the 2006 National Health Survey, that was completed by 29,478 persons. Variables studied: sociodemographics, psychological distress (GHQ-12), self-perceived health, mental disorder diagnosis, functional social support (Duke) and use and prescription of psychoactive medication. Results: The prevalence of psychological distress in Spain was 20,1%; the highest prevalence was found in Canary Islands (28,2%) and the lowest in La Rioja (12,2%). Among those who presented psychological distress, 62,4% had never received a mental disorder diagnosis, and 71,6% had not used psychoactive medication in the last year. The highest prevalences of non-diagnosed cases (81,8%) and cases non-treated with psychoactive medication (83,1%) were found in La Rioja, whereas the lowest prevalences were found in Asturias. Eight percent of the persons who presented psychological distress had low social support and 63,8% reported bad self-perceived health. Conclusions: Psychological distress is a prevalent phenomenon, and more than half of the persons who suffer it receive neither a diagnosis nor psychoactive medication. Moreover, there are considerable differences between the AC.

The influence of individual, social and physical environment factors on physical activity in the adult population in Andalusia, Spain

A person’s physical and social environment is considered as an influencing factor in terms of rates of engagement in physical activity. This study analyses the influence of socio-demographic, physical and social environmental factors on physical activity reported in the adult population in Andalusia. This is a cross-sectional study using data collected in the Andalusia Health Survey in 1999 and 2003. In addition to the influence of the individual’s characteristics, if there are no green spaces in the neighbourhood it is less likely that men and women will take exercise (OR = 1.26; 95% CI = 1.13, 1.41). Likewise, a higher local illiteracy rate also has a negative influence on exercise habits in men (OR = 1.39; 95% CI = 1.21, 1.59) and in women (OR = 1.22; 95% CI = 1.07, 1.40). Physical activity is influenced by individuals’ characteristics as well as by their social and physical environment, the most disadvantaged groups are less likely to engage in physical activity

Effectiveness of a nurse-led case management home care model in Primary Health Care. A quasi-experimental, controlled, multi-centre study

Background Demand for home care services has increased considerably, along with the growing complexity of cases and variability among resources and providers. Designing services that guarantee co-ordination and integration for providers and levels of care is of paramount importance. The aim of this study is to determine the effectiveness of a new case-management based, home care delivery model which has been implemented in Andalusia (Spain). Methods Quasi-experimental, controlled, non-randomised, multi-centre study on the population receiving home care services comparing the outcomes of the new model, which included nurse-led case management, versus the conventional one. Primary endpoints: functional status, satisfaction and use of healthcare resources. Secondary endpoints: recruitment and caregiver burden, mortality, institutionalisation, quality of life and family function. Analyses were performed at base-line, and at two, six and twelve months. A bivariate analysis was conducted with the Student's t-test, Mann-Whitney's U, and the chi squared test. Kaplan-Meier and log-rank tests were performed to compare survival and institutionalisation. A multivariate analysis was performed to pinpoint factors that impact on improvement of functional ability. Results Base-line differences in functional capacity – significantly lower in the intervention group (RR: 1.52 95%CI: 1.05–2.21; p = 0.0016) – disappeared at six months (RR: 1.31 95%CI: 0.87–1.98; p = 0.178). At six months, caregiver burden showed a slight reduction in the intervention group, whereas it increased notably in the control group (base-line Zarit Test: 57.06 95%CI: 54.77–59.34 vs. 60.50 95%CI: 53.63–67.37; p = 0.264), (Zarit Test at six months: 53.79 95%CI: 49.67–57.92 vs. 66.26 95%CI: 60.66–71.86 p = 0.002). Patients in the intervention group received more physiotherapy (7.92 CI95%: 5.22–10.62 vs. 3.24 95%CI: 1.37–5.310; p = 0.0001) and, on average, required fewer home care visits (9.40 95%CI: 7.89–10.92 vs.11.30 95%CI: 9.10–14.54). No differences were found in terms of frequency of visits to A&E or hospital re-admissions. Furthermore, patients in the control group perceived higher levels of satisfaction (16.88; 95%CI: 16.32–17.43; range: 0–21, vs. 14.65 95%CI: 13.61–15.68; p = 0,001). Conclusion A home care service model that includes nurse-led case management streamlines access to healthcare services and resources, while impacting positively on patients' functional ability and caregiver burden, with increased levels of satisfaction.

Validation of the Spanish version of the Index of Spouse Abuse

Background: Partner violence against women is a major public health problem. Although there are currently a number of validated screening and diagnostic tools that can be used to evaluate this type of violence, such tools are not available in Spain. The aim of this study is to analyze the validity and reliability of the Spanish version of the Index of Spouse Abuse (ISA). Methods: A cross-sectional study was carried out in 2005 in two health centers in Granada, Spain, in 390 women between 18 and 70 years old. Analyses of the factorial structure, internal consistency, test-retest reliability, and construct validity were conducted. Cutoff points for each subscale were also defined. For the construct validity analysis, the SF-36 perceived general health dimension, the Rosenberg Self-Esteem Scale and the Goldberg 12-item General Health Questionnaire were included. Results: The psychometric analysis shows that the instrument has good internal consistency, reproducibility, and construct validity. Conclusions: The scale is useful for the analysis of partner violence against women in both a research setting and a healthcare setting

Variability of indication criteria in knee and hip replacement: an observational study

BACKGROUND. Total knee (TKR) and hip (THR) replacement (arthroplasty) are effective surgical procedures that relieve pain, improve patients' quality of life and increase functional capacity. Studies on variations in medical practice usually place the indications for performing these procedures to be highly variable, because surgeons appear to follow different criteria when recommending surgery in patients with different severity levels. We therefore proposed a study to evaluate inter-hospital variability in arthroplasty indication. METHODS. The pre-surgical condition of 1603 patients included was compared by their personal characteristics, clinical situation and self-perceived health status. Patients were asked to complete two health-related quality of life questionnaires: the generic SF-12 (Short Form) and the specific WOMAC (Western Ontario and Mcmaster Universities) scale. The type of patient undergoing primary arthroplasty was similar in the 15 different hospitals evaluated.The variability in baseline WOMAC score between hospitals in THR and TKR indication was described by range, mean and standard deviation (SD), mean and standard deviation weighted by the number of procedures at each hospital, high/low ratio or extremal quotient (EQ5-95), variation coefficient (CV5-95) and weighted variation coefficient (WCV5-95) for 5-95 percentile range. The variability in subjective and objective signs was evaluated using median, range and WCV5-95. The appropriateness of the procedures performed was calculated using a specific threshold proposed by Quintana et al for assessing pain and functional capacity. RESULTS. The variability expressed as WCV5-95 was very low, between 0.05 and 0.11 for all three dimensions on WOMAC scale for both types of procedure in all participating hospitals. The variability in the physical and mental SF-12 components was very low for both types of procedure (0.08 and 0.07 for hip and 0.03 and 0.07 for knee surgery patients). However, a moderate-high variability was detected in subjective-objective signs. Among all the surgeries performed, approximately a quarter of them could be considered to be inappropriate. CONCLUSIONS. A greater inter-hospital variability was observed for objective than for subjective signs for both procedures, suggesting that the differences in clinical criteria followed by surgeons when indicating arthroplasty are the main responsible factors for the variation in surgery rates.

Influencia de un programa de actividad física en niños y adolescentes obesos; evaluación del estrés fisiológico mediante compuestos en la saliva; protocolo de estudio.

Different studies4, 5 relate that stress increases in children and adolescents with overweight and obesity, and consequently their salivary physiological responses (AEA salivary alpha-amylase, cortisol, cytokines, leptin), so in this study we relate these two parameters to see their progress through a program of physical activity. If we manage to reduce overweight or obesity, these physiological responses and stress should also be reduced, thus improving the overall health status of these children and adolescents. The overall objective of the study was to determine the influence of physical activity in obese children and adolescents in perceived stress. An observational, descriptive, prospective and longitudinal study will be carried out. The universe is made up of 60 overweight / obese children and adolescents aged between 10 and 18 years. The assessment will take place from September 2012 to September 2013. To collect saliva samples, the ELISA8 method will be used. Variables such as BMI, lifestyle and diet will also be collected. Among the expected results are to lower overweight and obesity in children through physical activity program. To reduce stress and to normalize physiological salivary parameters.

Physical activity is influenced by individuals' characteristics as well as by their social and physical environment, the most disadvantaged groups are less likely to engage in physical activity.

Detección de violencia contra la mujer en la consulta del médico de familia.

Objectives. To find out the magnitude of violence against female partners among patients who visit their family doctor. To study frequency and acceptance of its investigation by the family doctor and to assess the effectiveness of a screening question on abuse. Design. Descriptive, cross-sectional study. Setting. Primary care, 4 samples from 2 urban health centres in Jaén, Spain. Participants. Who participated 170 women randomly selected from the female consulting population. Measurements. Interviews by means of the Bradley modified test and the anxiety and depression Goldberg scales. Perceived health, frequency of detection of domestic violence, by the family doctor, and female opinions were also studied. Results. During the last year, abuse against women was detected in 22.9% of the female population consulting their family doctor (95% confidence interval [95% CI], 16.6-29.2). Abused women had a worse perception of health (odds ratio [OR] =4.2; 95% CI, 1.02-17.5) and a higher probability of depression (OR=4.7; 95% CI, 1.8-12.5) independently from the rest of variables. The question "How are the things going with your partner?" as a screening of abuse does obtain a positive probability quotient of 6.23 (95% CI, 3.6-10.9), a specificity of 89% and a negative predictive value of 90%. Of those interviewed, 96.5% would not mind if their family doctor approached the couple's relationships, a situation that occurs in 24.7% of cases. Conclusions. Some degree of abuse was detected in almost a quarter of women who consult their family doctor. Family doctors do not usually ask about family and partner relationships and environment, although for almost all women it is well appreciated and the item has an increased likelihood ratio and high negative predictive value in detecting abuse.
