Usefulness of the optic nerve sheath ultrasound in patients with cessation of cerebral flow.

Optic nerve sheath diameter (ONSD) ultrasound has proven to be a useful tool for the detection of intracranial hypertension (IH). The DVNO values, in patients with cessation of cerebral blood flow (CCBF), has not been clarified yet. OBJECTIVE: Establish an association between DVNO and CFSC in neurocritical patients admitted to an ICU. PATIENTS AND METHODS: Cross-sectional study of patients admitted in a third level ICU, between April 2017 and April 2018, with neurological pathology. ONSD ultrasound was performed in the first 24 h and as the patient was diagnosed of CCBF. The ONSD values of patients with and without diagnosis of CCBF were compared. RESULTS: 99 patients were included, 29 of whom showed CCBF in transcranial Doppler. The ONSD measurement did not demonstrate significant differences between both groups, 65.94 ±â€¯7.55 in the group with CCBF and 63.88 ±â€¯5.56 in the group without CCBF, p = 0.14. CONCLUSION: In our study, ONSD values capable of recognizing CCBF were not identified.

Development of a predictive model of hospitalization in primary care patients with heart failure.

BACKGROUND: Heart failure (HF) is the leading cause of hospitalization in people over age 65. Predictive hospital admission models have been developed to help reduce the number of these patients. AIM: To develop and internally validate a model to predict hospital admission in one-year for any non-programmed cause in heart failure patients receiving primary care treatment. DESIGN AND SETTING: Cohort study, prospective. Patients treated in family medicine clinics. METHODS: Logistic regression analysis was used to estimate the association between the predictors and the outcome, i.e. unplanned hospitalization over a 12-month period. The predictive model was built in several steps. The initial examination included a set of 31 predictors. Bootstrapping was used for internal validation. RESULTS: The study included 251 patients, 64 (25.5%) of whom were admitted to hospital for some unplanned cause over the 12 months following their date of inclusion in the study. Four predictive variables of hospitalization were identified: NYHA class III-IV, OR (95% CI) 2.46 (1.23-4.91); diabetes OR (95% CI) 1.94 (1.05-3.58); COPD OR (95% CI) 3.17 (1.45-6.94); MLHFQ Emotional OR (95% CI) 1.07 (1.02-1.12). AUC 0.723; R2N 0.17; Hosmer-Lemeshow 0.815. Internal validation AUC 0.706.; R2N 0.134. CONCLUSION: This is a simple model to predict hospitalization over a 12-month period based on four variables: NYHA functional class, diabetes, COPD and the emotional dimension of the MLHFQ scale. It has an acceptable discriminative capacity enabling the identification of patients at risk of hospitalization.

Disability and quality of life in heart failure patients: a cross-sectional study.

BACKGROUND: Although both hospitalization and mortality due to heart failure (HF) have been widely studied, less is known about the impact of HF on disability and quality of life. AIM: To assess the degree of disability and quality of life in HF patients attended at family medicine centres. DESIGN AND SETTING: Cross-sectional study of a cohort of HF patients attended at family medicine centres. METHODS: Disability was assessed with the WHODAS 2 questionnaire, which provides a global and six domain scores that is understanding and communication, getting around, self-care, getting along with people, life activities and participation in society. Quality of life was assessed with the Minnesota Living with Heart Failure Questionnaire, which furnishes a global and two domain scores, physical and emotional. RESULTS: A breakdown of the results showed that 28% of patients had moderate disability and 16.7% had severe disability, with the most important areas affected being: life activities, 8.9% extreme disability and 30.3% severe disability; getting around, 34.6% severe disability and 2% extreme disability; and participation in society, 53.3% moderate-severe disability. Quality of life was mildly affected. New York Heart Association (NYHA) Functional Classification and sex were the major determinants of disability and quality of life. Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists were associated with better scores in the "getting around" and "life activity" domains. CONCLUSION: HF patients in primary care show an important degree of disability and an acceptable quality of life.

Development and validation of a risk stratification model for prediction of disability and hospitalisation in patients with heart failure: a study protocol.

BACKGROUND: Chronic heart failure (CHF) reduces quality of life and causes hospitalisation and death. Identifying predictive factors of such events may help change the natural history of this condition. AIM: To develop and validate a stratification system for classifying patients with CHF, according to their degree of disability and need for hospitalisation due to any unscheduled cause, over a period of 1 year. METHODS AND ANALYSIS: Prospective, concurrent, cohort-type study in two towns in the Madrid autonomous region having a combined population of 1 32 851. The study will include patients aged over 18 years who meet the following diagnostic criteria: symptoms and typical signs of CHF (Framingham criteria) and left ventricular ejection fraction (EF)<50% or structural cardiac lesion and/or diastolic dysfunction in the presence of preserved EF (EF>50%).Outcome variables will be(a) Disability, as measured by the WHO Disability Assessment Schedule V.2.0 Questionnaire, and (b) unscheduled hospitalisations. The estimated sample size is 557 patients, 371 for predictive model development (development cohort) and 186 for validation purposes (validation cohort). Predictive models of disability or hospitalisation will be constructed using logistic regression techniques. The resulting model(s) will be validated by estimating the probability of outcomes of interest for each individual included in the validation cohort. ETHICS AND DISSEMINATION: The study protocol has been approved by the Clinical Research Ethics Committee of La Princesa University Teaching Hospital (PI-705). All results will be published in a peer-reviewed journal and shared with the medical community at conferences and scientific meetings.

Postdural puncture headache: impact of needle type, a randomized trial.

BACKGROUND CONTEXT: The most common adverse event after a lumbar puncture (LP) is a headache: In anaesthesiology, well studied is the protective effect of atraumatic spinal needles, and they are routinely used. However, this is less well known in diagnostic LP, and neurologists use atraumatic needles in less than 2% of times. PURPOSE: The purpose of this study was to define the impact of needle type, atraumatic (Sprotte [S]) versus traumatic (Quincke [Q]) on postdural puncture headache (PDPH) incidence. STUDY DESIGN: The study is based on a prospective, randomized, and simple-blinded clinical trial. PATIENT SAMPLE: Patients older than 14 years were scheduled for a diagnostic or therapeutic LP. OUTCOME MEASURES: The outcome measure included the development of PDPH according to the International Headache Association criteria. METHODS: Patients fulfilling eligibility criteria were randomly allocated to one of two kinds of spinal needle: atraumatic or S-type or traumatic or Q-type. They were interviewed on days 2 and 7 about the development of PDPH. RESULTS: The incidence of PDPH was 22.43% with Q-type needle and 8.51% with S-type needle, p=.04. The duration of PDPH in patients in the S-type was 1 day or less, compared with a median of 4.14 days in the Q-type (p=.00). In the logistic regression model, the S-type needle together with the age of the patient were the only two statistically significant factors in the development of postlumbar puncture headache (PLPH), both of them being protective. CONCLUSIONS: We found a lower incidence of PDPH with atraumatic needles, and it was statistically significant compared with the traumatic needles. Our study confirms the effectiveness of the atraumatic needles to prevent PDPH.

Natural History of Parkinson's Disease in the Province of Segovia: Disability in a 20 Years Longitudinal Study.

BACKGROUND: Parkinson's disease mainly affects the elderly population causing a progressive functional disability with motor, psychic, and cognitive deterioration. OBJECTIVE: This study was carried out to evaluate disability caused by Parkinson's disease by analyzing the median time to reach Hoehn and Yahr stage III and to investigate predictor variables based on a 20-year longitudinal follow-up study. METHODS: We examined 273 patients with Parkinson's disease recruited between 1978 and 1998. We performed a survival analysis using the Kaplan-Meier method to determine the time to disability and we used a Cox regression model to adjust prognosis factors. RESULTS: The median time to reach Hoehn and Yahr stage III was 7.73 years (95% CI: 5.95-8.05). Independent predictors of disability were: age at onset, the hazard ratio (HR) = 1.10, 95% CI: 1.08-1.12; UPDRS II (activities of daily living) HR = 1.08, 95% CI: 1.03-1.14; and akinesia and rigidity at onset HR = 1.55, 95% CI: 1.07-2.24. CONCLUSIONS: Patients with Parkinson's disease evolve gradually toward disability, and prognostic factors of this evolution were identified.

Heart failure in primary care: co-morbidity and utilization of health care resources.

BACKGROUND: In order to ensure proper management of primary care (PC) services, the efficiency of the health professionals tasked with such services must be known. Patients with heart failure (HF) are characterized by advanced age, high co-morbidity and high resource utilization. OBJECTIVE: To ascertain PC resource utilization by HF patients and variability in the management of such patients by GPs. METHODS: Descriptive, cross-sectional study targeting a population attended by 129 GPs over the course of 1 year. All patients with diagnosis of HF in their clinical histories were included, classified using the Adjusted Clinical Group system and then grouped into six resource utilization bands (RUBs). Resource utilization and Efficiency Index were both calculated. RESULTS: One hundred per cent of patients with HF were ranked in RUBs 3, 4 and 5. The highest GP visit rate was 20 and the lowest in excess of 10 visits per year. Prescription drug costs for these patients ranged from €885 to €1422 per patient per year. Health professional efficiency varied notably, even after adjustment for co-morbidity (Efficiency Index Variation Ratio of 28.27 for visits and 404.29 for prescription drug cost). CONCLUSIONS: Patients with HF register a high utilization of resources, and there is great variability in the management of such patients by health professionals, which cannot be accounted for by the degree of case complexity.

Comorbidity in patients with chronic obstructive pulmonary disease in family practice: a cross sectional study.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is frequent and often coexists with other diseases. The aim of this study was to quantify the prevalence of COPD and related chronic comorbidity among patients aged over 40 years visiting family practices in an area of Madrid. METHODS: An observational, descriptive, cross-sectional study was conducted in a health area of the Madrid Autonomous Region (Comunidad Autónoma de Madrid). The practice population totalled 198,670 persons attended by 129 Family Physicians (FPs), and the study population was made up of persons over the age of 40 years drawn from this practice population. Patients were deemed to have COPD if this diagnosis appeared on their clinical histories. Prevalence of COPD; prevalence of a further 25 chronic diseases in patients with COPD; and standardised prevalence ratios, were calculated. RESULTS: Prevalence of COPD in family medicine was 3.2% (95% CI 3.0-3.3) overall, 5.3% among men and 1.4% among women; 90% of patients presented with comorbidity, with a mean of 4 ± 2.04 chronic diseases per patient, with the most prevalent related diseases being arterial hypertension (52%), disorders of lipid metabolism (34%), obesity (25%), diabetes (20%) and arrhythmia (15%). After controlling for age and sex, the observed prevalence of the following ten chronic diseases was higher than expected: heart failure; chronic liver disease; asthma; generalised artherosclerosis; osteoporosis; ischaemic heart disease; thyroid disease; anxiety/depression; arrhythmia; and obesity. CONCLUSIONS: Patients with COPD, who are frequent in family practice, have a complex profile and pose a clinical and organisational challenge to FPs.

Disability transitions after 30 months in three community-dwelling diagnostic groups in Spain.

BACKGROUND: Little is known about changes in disability over time among community-dwelling patients. Accordingly, this study sought to assess medium-term disability transitions. PATIENTS AND METHODS: 300 chronic obstructive pulmonary disease (COPD), chronic heart failure and stroke patients living at home in Madrid were selected from general practitioner lists. In 2009, disability was assessed after a mean of 30 months using the World Health Organisation (WHO) Disability Assessment Schedule 2.0 (WHODAS 2.0). Follow-up was completed using death registries. Losses to follow-up were due to: death, 56; institutionalisation, 9; non-location, 18; and non-participation, 17. Changes in WHODAS 2.0 scores and life status were described and analysed using Cox and multinomial regression. Disability at end of follow-up was imputed for 56 deceased and 44 surviving patients. RESULTS: Mean disability scores for 200 surviving patients at end of follow-up were similar to baseline scores for the whole group, higher than their own baseline scores, and rose by 16.3% when imputed values were added. The strongest Cox predictors of death were: age over 84 years, adjusted hazard ratios with 95%CI 8.18 (3.06-21.85); severe/complete vs. no/mild disability, 5.18 (0.68-39.48); and stroke compared to COPD, 1.40 (0.67-2.91). Non-participants and institutionalised patients had higher proportions with severe/complete baseline disability. A one-point change in baseline WHODAS 2.0 score predicted independent increases in risk of 12% (8%-15%) for severe/complete disability or death. CONCLUSIONS: A considerably high proportion of community-dwelling patients diagnosed with COPD, CHF and stroke undergo medium-term changes in disability or vital status. The main features of the emerging pattern for this group appear to be as follows: approximately two-thirds of patients continue living at home with moderately reduced functional status; 1/3 die or worsen to severe/complete disability; and 1/10 improve. Baseline disability scores, age and diagnosis are associated with disability and death in the medium term.

Comorbidity patterns in patients with chronic diseases in general practice.

INTRODUCTION: Healthcare management is oriented toward single diseases, yet multimorbidity is nevertheless the rule and there is a tendency for certain diseases to occur in clusters. This study sought to identify comorbidity patterns in patients with chronic diseases, by reference to number of comorbidities, age and sex, in a population receiving medical care from 129 general practitioners in Spain, in 2007. METHODS: A cross-sectional study was conducted in a health-area setting of the Madrid Autonomous Region (Comunidad Autónoma), covering a population of 198,670 individuals aged over 14 years. Multiple correspondences were analyzed to identify the clustering patterns of the conditions targeted. RESULTS: Forty-two percent (95% confidence interval [CI]: 41.8-42.2) of the registered population had at least one chronic condition. In all, 24.5% (95% CI: 24.3-24.6) of the population presented with multimorbidity. In the correspondence analysis, 98.3% of the total information was accounted for by three dimensions. The following four, age- and sex-related comorbidity patterns were identified: pattern B, showing a high comorbidity rate; pattern C, showing a low comorbidity rate; and two patterns, A and D, showing intermediate comorbidity rates. CONCLUSIONS: Four comorbidity patterns could be identified which grouped diseases as follows: one showing diseases with a high comorbidity burden; one showing diseases with a low comorbidity burden; and two showing diseases with an intermediate comorbidity burden.

ICF disability measured by WHO-DAS II in three community diagnostic groups in Madrid, Spain.

OBJECTIVE: The planning, provision and monitoring of medical and support services for patient groups with chronic ailments may require disability assessment and registration. The purpose of this study was to assess disability in three groups of patients with chronic obstructive pulmonary disease (COPD), chronic heart failure (CHF) or stroke. METHODS: Convenience samples of consecutive patients diagnosed with COPD (102), CHF (99), and stroke (99) were taken from 1,053 primary care users in the southern area of the autonomous region of Madrid. The patients were informed of the study and were assessed in their homes by trained field workers using the World Health Organization Disability Assessment Schedule II (WHO-DAS II). RESULTS: None of the groups had patients with extreme disability on their global WHO-DAS II scores. The prevalence of severe disability differed among the groups and was highest for stroke and CHF (33.33% and 29.29%, respectively) and lowest for COPD (14.71%). The three groups shared two similar traits, namely, a higher prevalence of disability among women than men, and a specific pattern by domain, with the highest prevalence of severe/extreme limitations being found in household life activities and mobility. Severe restrictions in Social Participation were more frequent in patients with stroke and CHF. The group with moderate disability according to the global WHODAS II score (n=94) showed a high prevalence of severe limitations in mobility, life activities and self-care. CONCLUSIONS: Disability among non-institutionalized persons with COPD, CHF and stroke is frequent and shows gender- and domain-related patterns similar to those described in a population-based study performed using the WHO-DAS II in elderly persons in Spain. ICF-validated disability categories could be useful in epidemiological surveys, individual assessments and primary care data monitoring systems.

Objetivo: La planificación, prestación y monitorización de servicios sociales y sanitarios a pacientes con trastornos crónicos puede requerir evaluación y registro de su discapacidad. El objetivo de este estudio fue evaluar la discapacidad de tres grupos de pacientes con enfermedad pulmonar obstructiva crónica (EPOC), insuficiencia cardiaca congestiva (ICC) o ictus. Métodos: Pacientes con EPOC (102), ICC (99) e ictus (99), vistos consecutivamente, identificados de una lista de 1053 usuarios de atención primaria en el sur de la Comunidad Autónoma de Madrid, España. Tras ser informados, fueron evaluados en sus casas por entrevistadores entrenados utilizando WHODAS-2. Resultados: No hubo casos de discapacidad extrema, pero las tres poblaciones mostraron prevalencias de discapacidad grave según WHODAS-2 total, más altas en ictus e ICC (33,33% y 29,29%, respectivamente) y menores en EPOC (14,71%). Los grupos compartían un patrón de discapacidad más alta en mujeres y otro específico por dominios, con prevalencias más altas de discapacidad grave/extrema en actividades domésticas y movilidad. La participación social estaba más restringida en ictus e ICC. El grupo con discapacidad moderada en WHODAS-2 global (94 enfermos) mostraba prevalencias altas de discapacidad grave en movilidad, actividades diarias domésticas y autocuidado. Conclusiones: La discapacidad en personas no institucionalizadas con EPOC, ICC e ictus es frecuente, con patrones por sexo y dominio similares a los descritos en España con WHODAS-2 en un estudio poblacional de personas de edad avanzada. Las categorías CIF de discapacidad podrían utilizarse en encuestas epidemiológicas y evaluaciones individuales, así como en sistemas de información orientados a la monitorización de la discapacidad en atención primaria (AU)

Heart failure in the family practice: a study of the prevalence and co-morbidity.

BACKGROUND: Heart failure (HF) is a health problem that particularly affects the elderly population. Its onset is associated with other chronic diseases, a circumstance that makes it a challenge for health care services. The aim of this study is to quantify the prevalence of HF in family medicine offices and describe the chronic co-morbidity associated with it. METHODS: A cross-sectional, observational descriptive study set in a health area of the Community of Madrid, Spain. The study was carried out in a population of 198,670 individuals over 14 years of age, attended to by 129 specialists in family medicine. The patient was considered to have HF when this diagnosis (ICPC code K77) appeared in his or her electronic medical record. The prevalence of HF was quantified and its association with another 25 chronic diseases was analysed. RESULTS: The prevalence of HF was 6.9‰, 7.9‰ among women and 5.9‰ among men. Patients with HF had a high rate of chronic co-morbidity, with an average of 5.2 + 2.1 chronic diseases. Only 3% of the patients present with isolated HF and >60% have four or more additional chronic problems. Hypertension, cardiac arrhythmias, hyperlipidaemia, obesity and diabetes mellitus are the chronic diseases most frequently detected in HF patients. CONCLUSION: Patients with HF frequently visit the offices of family physicians, presenting with a high rate of cardiac and non-cardiac co-morbidity that proves to be a challenge on the clinical level and in terms of the organization of health care services.

Impact of patient-general practitioner short-messages-based interaction on the control of hypertension in a follow-up service for low-to-medium risk hypertensive patients: a randomized controlled trial.

The evaluation in real-life settings of services for the follow-up and control of hypertensive patients is a complex intervention, which still needs analysis of the roles, tasks, and resources involved in the basic items: patient, healthcare professional, and the interaction between the two. To evaluate the impact of patient-general practitioner (GP) short-messages-based interaction, isolated from other items, on the degree of hypertension control in the follow-up of medium-to-low-risk patients in primary care, a randomized controlled trial has been performed: 38 GPs enrolled 285 hypertensive patients who recorded the results of self-blood-pressure (BP) monitoring, heart rate, and body weight, and completed an optional questionnaire in an identical manner over a six-month period. The telemedicine group (TmG) sent the data to a telemedicine-based system that enabled patient-GP interaction; the control group (CG) recorded the data on paper and could only deliver it to their GP personally in the routine visits. In the TmG, the results were better, but not significantly so, for: 1) degree of hypertension control, in terms of the percentage of uncontrolled hypertensives at the final visit (TmG versus CG: 31.7% versus 35.6%; p = 0.47); 2) reduction in hypertension during follow-up, comparing measurements (performed by a professional) at the initial and final visits of systolic BP (15.5 versus 11.9; p = 0.13) and diastolic BP (9.6 versus 4.4; p = 0.40); and 3) adherence to the protocol within compliance levels of interest in a real-life follow-up service: >>50% (84.8% versus 73.3%) and >>25% (92.4.8% versus 75.4%) ( p = 0.053). Other factors such as average values of self-measured systolic BP, diastolic BP and heart rate, acceptability of the protocol, and median number of consultations and hospital admissions were similar in both groups. Outcomes show that, taken alone, the patient-GP short-messages-based interaction has very little impact on the degree of hypertension control in patients with this profile. In complex interventions, to discriminate the impact of each of its components in isolation will enable us to design an efficient follow-up service, little demanding in terms of healthcare professional dedication, and optimized in other basic aspects.
