Impact of Anxiety and Depression on Disease Control and Quality of Life in Asthma Patients

Introduction. Patients with asthma also tend to have anxiety and depression. These comorbidities may affect asthma control and quality of life. The objective of this study was to assess the impact of anxiety and depression on asthma control and quality of life. Patients and methods. Cross-sectional study of asthma outpatients was conducted at two hospitals in the Basque Country (northern Spain). Data collected included sociodemographic variables, asthma symptoms, treatment, number of exacerbations, level of control, quality of life, presence of psychological morbidities, and level of physical activity. Spirometry was performed in accordance with the recommendations of the Spanish Society of Pneumology and Thoracic Surgery. Results. Among 354 asthmatics, 77% had poor or partial control of their condition, 31% had anxiety alone, 2% had depression alone, and 10% had anxiety plus depression. Poor asthma control was associated with anxiety plus depression (odds ratio (OR): 3.61; 95% confidence interval (CI): 1.05–12.41) as well as with female patients (OR: 1.85; 95% CI: 1.11–3.10). Anxiety had an independent effect on reduced quality of life across all domains; anxiety plus depression had an even greater effect. Conclusion. Among patients with asthma, anxiety and depression adversely affect asthma control and quality of life, raising the possibility that treating these psychological comorbidities could improve asthma control and quality of life.

Impact of hospitalisations for exacerbations of COPD on health-related quality of life

Exacerbations of chronic obstructive pulmonary disease (COPD) impair health-related quality of life (HRQoL). It is unknown whether exacerbations requiring hospitalisation have an impact on HRQoL. 611 ambulatory COPD patients were prospectively identified. The average age (SD) was 65.5 (8.6), FEV(1) (SD) was 52% (14%) of the predicted value. All patients completed the Saint Georges Respiratory Questionnaire (SGRQ) and the Medical Outcomes Study Short Form (SF-36) questionnaire at the beginning of the study. After five years of follow-up, the 391 survivors again completed these HRQoL instruments. No changes in HRQoL were observed among patients not hospitalised for COPD exacerbations. Those hospitalised during follow-up experienced significant declines in HRQoL. The largest changes were observed among patients with >or=3 hospitalisations, with a 13.6 unit increase in the total SGRQ and a 10.5 unit decrease in the physical component summary scale of the SF-36. Similar changes were observed among patients with FEV(1)>or=50% at baseline. In the multivariate analysis, after adjustment by FEV(1%), age, comorbidities, and HRQoL in the respective HRQoL domain at baseline, hospitalisations were an independent predictor of the change in HRQoL. Hospitalisations for exacerbations of COPD have an independent and negative impact on the evolution of HRQoL, regardless of COPD severity.

BODE-Index vs HADO-Score in Chronic Obstructive Pulmonary Disease: Which one to use in general practice?

BackgroundForced expiratory volume in one second (FEV1) is used to diagnose and establish a prognosis in chronic obstructive pulmonary disease (COPD). Using multi-dimensional scores improves this predictive capacity.Two instruments, the BODE-index (Body mass index, Obstruction, Dyspnea, Exercise capacity) and the HADO-score (Health, Activity, Dyspnea, Obstruction), were compared in the prediction of mortality among COPD patients.MethodsThis is a prospective longitudinal study. During one year (2003 to 2004), 543 consecutively COPD patients were recruited in five outpatient clinics and followed for three years. The endpoints were all-causes and respiratory mortality.ResultsIn the multivariate analysis of patients with FEV1 < 50%, no significant differences were observed in all-cause or respiratory mortality across HADO categories, while significant differences were observed between patients with a lower BODE (less severe disease) and those with a higher BODE (greater severity). Among patients with FEV1 ≥ 50%, statistically significant differences were observed across HADO categories for all-cause and respiratory mortality, while differences were observed across BODE categories only in all-cause mortality.ConclusionsHADO-score and BODE-index were good predictors of all-cause and respiratory mortality in the entire cohort. In patients with severe COPD (FEV1 < 50%) the BODE index was a better predictor of mortality whereas in patients with mild or moderate COPD (FEV1 ≥ 50%), the HADO-score was as good a predictor of respiratory mortality as the BODE-index. These differences suggest that the HADO-score and BODE-index could be used for different patient populations and at different healthcare levels, but can be used complementarily.

Changes in the Prevalence of Asthma in the Spanish Cohort of the European Community Respiratory Health Survey (ECRHS-II)

OBJECTIVE The rise in the prevalence of asthma in the second half of the 20th century has not been evenly distributed according to recent surveys. We assessed changes in the prevalence of asthma after a period of 9 to 10 years in a cohort of young adults in the Spanish arm of the European Community Respiratory Health Survey (ECRHS). MATERIAL AND METHODS The ECRHS-II is a multicenter cohort study taking place in 27 centers around Europe, with Spanish centers located in Albacete, Barcelona, Galdakao, Huelva, and Oviedo. The ECRHS questionnaire was administered to individuals who had participated in the first phase of the survey; spirometry and methacholine challenge tests were also performed according to the published protocol. RESULTS Among new smokers, the prevalence of wheezing in the last 12 months increased from 10% to 33%, while the frequency of phlegm production rose from 8% to 22% (P< .05). In ex-smokers, the prevalences of wheezing and phlegm production decreased from 21% to 12% and from 15% to 8%, respectively (P< .05). Symptom prevalences remained similar for never smokers, although the frequency of diagnosed asthma rose from 4% to 7% (P< .05). After adjusting for smoking, age, sex, and center, we found no significant differences in the frequency of symptoms or asthma, even when the phrase bronchial hyperreactivity was included in the definition. However, the rate of reported asthma rose annually by 0.34% (95% confidence interval [CI], 0.20%-0.48%), while diagnosed asthma rose by 0.26% (95% CI, 0.13%-0.39%) and treated asthma by 0.16% (95% CI, 0.07%-0.25%). CONCLUSIONS Increased prevalence rates of asthma diagnosis and treatment have been detected, but the rates of reported symptoms have remained similar, consistent with the assumption that more persons are being classified as asthmatics.

Caregivers consequences of care among patients with eating disorders, depression or schizophrenia.

BackgroundThe consequences of caring for a person with a mental illness can impose a substantial burden. Few studies have compared this burden among caregivers of patients with eating disorders and other mental illnesses. The objective of this study was to compare caregiver consequences in eating disorders (ED) with caregiver consequences in depression and schizophrenia, assessed with the same instrument, the Involvement Evaluation Questionnaire (IEQ). Another aim was to identify factors that may predict these consequences.MethodsWe conducted a cross-sectional study involving 251 caregivers of ED patients; 252 caregivers of patients with depression; and 151 caregivers of patients with schizophrenia. Caregivers completed the Involvement Evaluation Questionnaire EU Version (IEQ-EU). Descriptive statistics, ANOVA, and Chi-square were applied to examine the inter-variable relationships. Consequences- indexes were also computed.ResultsIn all samples, worrying was the most commonly reported consequence of caregiving. Predictive variables for a high level of caregiver burden included being a mother or partner of the person being cared for (p = <.01), and being a caregiver of a patient with ED.ConclusionsThe burden of caregiving is higher among caregivers of patients with eating disorders patients than among caregivers of patients with depression or schizophrenia. Our findings suggest that caregivers of patients with an ED could benefit from providing adequate assessment and support.

Detecting depression in medically ill patients: Comparative accuracy of four screening questionnaires and physicians' diagnoses in Spanish population

OBJECTIVE The purpose of this study is to compare the diagnostic accuracy of four depression screening tools commonly used in patients with medical disorders, relative to a reference diagnostic standard-a structured psychiatric interview. METHODS The Depression in the Medically Ill-18 (DMI-18) questionnaire was administered to 167 patients with medical disorders; of those, 53 completed the Beck Depression Inventory for Primary Care (BDI-PC), 67 the Hospital Anxiety and Depression Scale (HADS), and 46 the Patient Health Questionnaire-9 (PHQ-9). The entire sample was also interviewed with a structured psychiatric interview conducted by a mental health professional. Sensitivity, specificity, likelihood ratios (LRs), and area under the curve (AUC) were calculated and compared for the different measures. RESULTS At their respective recommended cutoff points, sensitivities [95% confidence interval (CI)] were 86% (70-95), 82% (63-94), 93% (86-97), and 68% (47-85) for the HADS-D, BDI-PC, DMI-18, and PHQ-9, respectively, while specificities ranged from 72% (47-90) for BDI-PC to 89% (72-98) for PHQ-9. The sensitivities of DMI-18 were significantly higher compared to those of HADS-D (P=.045) and PHQ-9 (P=.01). The PHQ-9 questionnaire obtained the most favorable positive LR (6.35; 95% CI, 2.48-18.36). In contrast, the DMI-18 showed the best negative LR (0.09; 95% CI, 0.04-0.18). Areas under the curves (95% CI) ranged from 0.92 (0.83-1.02) to 0.84 (0.74-0.94). Statistically significant differences were found between the AUCs of the DMI-10 and the BDI-PC. CONCLUSION Our results suggest that all evaluated scales have acceptable abilities and can be used as screening instruments for depression in patients with medical disorders. The DMI stands out for its sensitivity.

Predictors of quality of life and caregiver burden among maternal and paternal caregivers of patients with eating disorders

This prospective study investigated quality of life and caregiver burden of 244 parent caregivers of 113 Spanish patients with Eating Disorders (ED). One hundred eleven mothers and 70 fathers fulfilled the inclusion criteria. ED patients completed the Hospital Anxiety and Depression Scale (HADS) and the Eating Attitudes Test-26. Caregivers completed the HADS, the Short Form-12 (SF-12), the Involvement Evaluation Questionnaire-EU version, and the Anorectic Behaviour Observation Scale. Descriptive statistics, ANOVA, Chi-square and Fishers exact test were applied. Among mothers, anxiety and depression and patient age contributed to poorer quality of life. Caregiver variables that affected the burden for mothers were marital status, the mental subscale of the SF-12, and the mothers perception of the severity of her childs illness. Caregiver variables that affected the burden for fathers were the caregivers anxiety and the physical domain of the SF-12. Among mothers but not fathers, being married was a protective factor of caregiver burden. Our findings suggest that mothers and fathers have different perceptions of their quality of life and caregiver burden, and that mothers of patients with ED may be in considerable need for extra psychosocial support.

Development and Validation of Clinical Scores for Visual Outcomes after Cataract Surgery

PURPOSE To develop and validate a clinical score to predict visual acuity (VA) and functional changes after phacoemulsification on the basis of readily obtainable preoperative history data and patient assessment. DESIGN Prospective follow-up study. PARTICIPANTS A sample of 5512 patients on waiting lists for phacoemulsification at 17 hospitals in Spain. METHODS Data were obtained at the baseline examination from the 5512 patients. The patients were divided randomly into 2 subgroups: derivation (n = 3285; 60%) and validation (n = 2227; 40%). The preoperative predictors of postoperative gains in VA and visual function index 14 (VF-14) were determined by multivariate logistic regression analysis and implemented using a prediction score. MAIN OUTCOME MEASURES Probability of postoperative improvement in VA and VF-14 scores. The cutoff points were established for each outcome on the basis of the minimal clinically important difference values. RESULTS The predictive variables for VA gain were the baseline VA, patient age, ocular comorbidity, and surgical complexity. Regarding the VF-14, the predictive factors were the preoperative VF-14, the eye with the better VA, and the surgical complexity. In the multivariate logistic model in the derivation sample, the final VA and VF-14 scores ranged from 0 to 44 and from 0 and 24, respectively. Receiver operating characteristic curves were developed in the derivation and validation samples, and no statistical significance was found when their areas under the curve were compared. Areas under the curve ranged from 65% to 80%. Both scores had a positive predictive value from 74% to 85%. CONCLUSIONS Newly developed and validated clinical prediction scores may assist physicians and patients in decision making about the expected outcomes and benefits of cataract surgery.
