[Effectiveness of double-layered compression therapy against crepe bandage for healing venous ulcers in primary care. Randomized clinical trial]. / Efectividad de la terapia compresiva de doble capa frente al vendaje de crepé en la cicatrización de úlceras venosas en atención primaria. Ensayo clínico aleatorizado.

OBJECTIVE: To evaluate if the two-layer bandage is more effective than the crepe bandage in the healing of venous ulcers after 12 weeks of follow-up. DESIGN: Randomized multicentre controlled clinical trial. LOCATION: 22 Primary Health Centers of Madrid. PARTICIPANTS: Over 18 years old, with diagnosis of venous ulcers. 93 patients were randomized, 56 in the double layer group and 37 in the crepe group. Withdrawals: 16 in double layer group, 7 in crepe group. INTERVENTIONS: Control group: usual clinical practice: treatment of the wound and bandage with crepe. Experimental group: same usual clinical practice for wound treatment and bandage with double layer. MAIN MEASUREMENTS: Primary outcome: complete healing at 12 weeks. SECONDARY OUTCOMES: severity of ulceration, health-related quality of life, adverse events. Blind evaluation of the response variable. RESULTS: Complete healing: in crepe group, 25, 67.5% (95% CI 50.2-81.9) and in double layer group, 32, 57.1% (95% CI 43.2-70.3). No evidence of a difference in both groups, RR=1.10 (95% CI 0.864-1.424). The basal severity of the ulcers is associated with the healing time. HR=0.86 (95% CI 0.78-0.94). Our data showed a significant improvement in health-related quality of life, total and in the of cosmesis and emotional dimensions. No evidence of a difference in both groups. We didn't find serious adverse events in any of the groups. CONCLUSIONS: We didn't find significant differences in the healing between the two bandages evaluated. Both are appropriate for ulcer healing and to improve the health-related quality of life.

ECAMulticapa: Effectiveness of double-layered compression therapy for healing venous ulcers in primary care: a Study Protocol.

BACKGROUND: Chronic venous insufficiency, in its final stage can cause venous ulcers. Venous ulcers have a prevalence of 0.5 % to 0.8 % in the general population, and increases starting at 60 years of age. This condition often causes increased dependency in affected individuals, as well as a perceived reduced quality of life and family overload. Local Treating chronic venous ulcers has 2 components: topically healing the ulcer and controlling the venous insufficiency. There is evidence that compressive therapy favours the healing process of venous ulcers. The studies we have found suggest that the use of multilayer bandage systems is more effective than the use of bandages with a single component, these are mostly using in Spain. Multilayer compression bandages with 2 layers are equally effective in the healing process of chronic venous ulcers as 4-layer bandages and are better tolerated and preferenced by patients. More studies are needed to specifically compare the 2-layer bandages systems in the settings where these patients are usually treated. METHOD/DESIGN: Randomised, controlled, parallel, multicentre clinical trial, with 12 weeks of follow-up and blind evaluation of the response variable. The objective is to assess the efficacy of multilayer compression bandages (2 layers) compared with crepe bandages, based on the incidence of healed venous ulcers in individuals treated in primary care nursing consultations, at 12 weeks of follow-up. The study will include 216 individuals (108 per branch) with venous ulcers treated in primary care nursing consultations. The primary endpoint is complete healing at 12 weeks of follow-up. The secondary endpoints are the degree of healing (Resvech.2), quality of life (CCVUQ-e), adverse reactions related to the healing process. Prognosis and demographic variables are also recorder. Effectiveness analysis using Kaplan-Meier curves, a log-rank test and a Cox regression analysis. The analysis was performed by intention to treat. DISCUSSION: The study results can contribute to improving the care and quality of life of patients with venous ulcers, decreasing healing times and healthcare expenditure and contributing to the consistent treatment of these lesions. TRIAL REGISTRATION: This study has been recorded in the Clinical Trials.gov site with the code NCT02364921. 17 February 2015.

[Ability to detect psychiatric disorders by the family physician]. / Capacidad de detección de patología psiquiátrica por el médico de familia.

OBJECTIVE: To determine the ability of family physicians to detect psychiatric disorders, comparing the presence of psychiatric disorders detected using validated tests and referrals by family physicians. DESIGN: Cross-sectional, two-phase study. LOCATION: Primary healthcare centres in an urban area of Madrid. PARTICIPANTS: Patients between 18 and 65years attending primary healthcare centres for non-administrative purposes. MAIN MEASUREMENTS: To detect psychiatric disorders in the waiting room, an interview was performed using GHQ-28 and MULTICAGE CAD-4 in the screening phase (considered positive: score of 6 or higher on the GHQ-28 or a score 2 or higher on MULTICAGE CAD-4). Patients with a positive score and 20% with negative were recruited for the second phase (case identification) using MINI interview. During family physician consultation, the patient gave his doctor a card with an identification number to record the presence of psychiatric illness in his/her opinion and whether there was treatment with psychotropic drugs. RESULTS: A total of 628 subjects participated. The prevalence of psychiatric disorders corrected by two phase methodology was 31.7% (95%CI: 27.9 to 35.5). Of the 185 patients with a psychiatric disorder detected, 44.2% (95%CI: 36.7 to 51.7) were identified as patients with psychiatric disorders by their family physician. Disorders best detected were: hypomania, dysthymic disorder, depressive episode with melancholic symptoms, and panic disorder. CONCLUSIONS: A significant percentage of patients with possible psychiatric disorders detected with validated test have not been identified by their family physician.

[Survival of patients with heart failure in primary care]. / Supervivencia de pacientes con insuficiencia cardiaca en atención primaria.

OBJECTIVE: To describe survival of patients with chronic heart failure (HF) followed up in primary care (PC) and analyse the effect of sex, age, clinical and health services factors, and income levels on survival. DESIGN: Longitudinal observational study of a retrospective cohort of patients with information extracted from electronic medical records. SETTING: PC Area 7 of the Community of Madrid. PARTICIPANTS: Patients 24 year and older with at least one visit to PC in 2006. PRINCIPAL MEASUREMENT: Incident cases of HF followed up from 2006 to 2010 or until death. Survival analysis with Kaplan-Meier and Cox proportional hazard multivariate regression. RESULTS: A total of 3,061 cases were identified in a cohort of 227,984 patients. The survival rate was 65% at 5 years, with 519 patients dying with a median survival of 49 months. Factors associated with increased risk of mortality were, age (HR=1.04, 1.03-1.05), and having a diagnosis of ischemic heart disease (HR=1.45, 1.15- 1.78), or diabetes (HR=1.52, 1.17-1.95). Factors with a significant protective effect were: female sex (HR=0.72, 0.59-0.86), non-pensioner (HR=0.43, 0.23-0.84), having received the influenza vaccine annually (HR=0.01, 0.00-0.06), prescribed lipid-lowering drugs (HR=0.78, 0.61-0.99) or ACE inhibitors (HR=0.73, 0.60-0.88), and blood tests having been requested (HR=0.97, 0.95-1.00), X-rays (HR=0.81, 0.74-0.88), or electrocardiograms (HR=0.90, 0.81-0.99) in PC. CONCLUSIONS: Data from patients with HF followed up in PC indicate that their survival is better than that obtained in other countries, supporting the argument of a better evolution of HF in Mediterranean countries.

Implementation of a virtual community of practice to promote the empowerment of middle-aged people with multimorbidity: study protocol of a randomised controlled trial.

INTRODUCTION: Empowering people living with multimorbidity (multiple chronic conditions) to gain greater confidence in managing their health can enhance their quality of life. Education focused on self-management is a key tool for fostering patient empowerment and is mostly provided on an individual basis. Virtual communities of practice (VCoP) present a unique opportunity for online education in chronic condition self-management within a social context. This research aims to evaluate the effectiveness/cost-effectiveness of individualised, online self-management education compared with VCoP among middle-aged individuals living with multiple chronic conditions. METHODS AND ANALYSIS: People aged 30-60, living with ≥2 chronic conditions and receiving care in primary care (PC) centres and outpatient hospital-based clinics in Madrid and Canary Islands will enrol in an 18-month parallel-design, blinded (intervention assessment and data analysts), pragmatic (adhering to the intention-to-treat principle), individually randomised trial. The trial will compare two 12-month web-based educational offers of identical content; one delivered individually (control) and the other with online social interaction (VCoP, intervention). Using repeated measures mixed linear models, with the patient as random effect and allocation groups and time per group as fixed effects, we will estimate between-arm differences in the change in Patient Activation Measure from baseline to 12 months (primary endpoint), including measurements at 6-month and 18-month follow-up. Other outcomes will include measures of depression and anxiety, treatment burden, quality of life. In addition to a process evaluation of the VCoP, we will conduct an economic evaluation estimating the relative cost-effectiveness of the VCoP from the perspectives of both the National Health System and the Community. ETHICS AND DISSEMINATION: The trial was approved by Clinical Research Ethics Committees of Gregorio Marañón University Hospital in Madrid/Nuestra Señora Candelaria University Hospital in Santa Cruz de Tenerife. The results will be disseminated through workshops, policy briefs, peer-reviewed publications and local/international conferences. TRIAL REGISTRATION NUMBER: NCT06046326.

Oral versus intramuscular administration of vitamin B12 for the treatment of patients with vitamin B12 deficiency: a pragmatic, randomised, multicentre, non-inferiority clinical trial undertaken in the primary healthcare setting (Project OB12).

BACKGROUND: The oral administration of vitamin B12 offers a potentially simpler and cheaper alternative to parenteral administration, but its effectiveness has not been definitively demonstrated. The following protocol was designed to compare the effectiveness of orally and intramuscularly administered vitamin B12 in the treatment of patients ≥65 years of age with vitamin B12 deficiency. METHODS/DESIGN: The proposed study involves a controlled, randomised, multicentre, parallel, non-inferiority clinical trial lasting one year, involving 23 primary healthcare centres in the Madrid region (Spain), and patients ≥65 years of age. The minimum number of patients required for the study was calculated as 320 (160 in each arm). Bearing in mind an estimated 8-10% prevalence of vitamin B12 deficiency among the population of this age group, an initial sample of 3556 patients will need to be recruited. Eligible patients will be randomly assigned to one of the two treatment arms. In the intramuscular treatment arm, vitamin B12 will be administered as follows: 1 mg on alternate days in weeks 1 and 2, 1 mg/week in weeks 3-8,and 1 mg/month in weeks 9-52. In the oral arm, the vitamin will be administered as: 1 mg/day in weeks 1-8 and 1 mg/week in weeks 9-52. The main outcome variable to be monitored in both treatment arms is the normalisation of the serum vitamin B12 concentration at weeks 8, 26 and 52; the secondary outcome variables include the serum concentration of vitamin B12 (in pg/ml), adherence to treatment, quality of life (EuroQoL-5D questionnaire), patient 3satisfaction and patient preferences. All statistical tests will be performed with intention to treat and per protocol. Logistic regression with random effects will be used to adjust for prognostic factors. Confounding factors or factors that might alter the effect recorded will be taken into account in analyses. DISCUSSION: The results of this study should help establish, taking quality of life into account, whether the oral administration of vitamin B12 is an effective alternative to its intramuscular administration. If this administration route is effective, it should provide a cheaper means of treating vitamin B12 deficiency while inducing fewer adverse effects. Having such an alternative would also allow patient preferences to be taken into consideration at the time of prescribing treatment. TRIAL REGISTRATION: This trial has been registered with ClinicalTrials.gov, number NCT 01476007, and under EUDRACT number 2010-024129-20.

[Research and protection of personal data in Primary Care]. / Investigación y protección de datos personales en atención primaria.

Research is one of the fundamental functions that have to be carried out in Primary Care. The clinical information stored in different records arising from medical care is a basic tool for this activity. The use of personal data for the purposes of research is legitimate according to our laws; however, this information must be treated confidentially at all times. Two alternatives are available for this. One is to obtain the informed consent of the patient, and the other is to dissociate the handling of the information. But in some situations, the compliance to legal demands when obtaining data for research is not easy, there being a series of obstacles which in many cases makes it impossible to carry out research. In this article, we will give guidance on how to access the information contained in records while respecting the rights of the patient and the current legislation.

Factors Associated With the Quality of Life of Patients With Venous Leg Ulcers in Primary Care: Cross-Sectional Study.

The presence of venous leg ulcers (VLU) is associated with emotional disorders in individuals who have conditions, such as depression, anxiety, and sleeping problems, which result in a reduced perceived quality of life by these individuals. The study aim was to describe the perceived quality of life and associated factors for individuals with VLU. We conducted a cross-sectional study in 22 primary care health centers with a sample of 93 individuals with VLU. The variables collected were the following: perceived quality of life measured with Spanish version of the Charing Cross Venous Ulcer Questionnaire (CCVUQ-e), ulcer severity measured with the RESVECH 2.0 Score, demographic variables, and those related to the healing process. The results showed a mean CCVUQ-e score of 47.4 ± 11.8 points (Mean ± SD), with the most affected dimension being the emotional status, followed by cosmesis, social interaction, and domestic activities. The mean RESVECH 2.0 score was 11.1 ± 3.7 points. An association was found between ulcer-related pain and poorer quality of life (P < .05, t test) and between erythema in perilesional skin and poorer quality life (P < .05, t test). The signs of infection and inflammation in the VLUs were as follows: increasing exudate, friable tissue, and biofilm-compatible tissue, which were associated with a poorer quality of life (P < .05, t test). The multivariate model was statistically significant and explained a variability of 26% in the CCVUQ-e score. This study confirms that wound severity, pain, and signs of infection in VLU decrease the perceived quality of life of individuals with these wounds.

Carotid intima-media thickness as a screening tool in cardiovascular primary prevention.

BACKGROUND AND OBJECTIVE: Increased carotid intima-media thickness (CIMT) is associated with cardiovascular events. The purpose of this study was to identify advanced subclinical atherosclerosis in patients who are at low or intermediate risk. METHODS: Thousand hundred and eighteen Spanish subjects were prospectively enrolled in an ambulatory screening of cardiovascular risk (CVR). Three hundred and twenty patients aged over 30 years with low-intermediate CVR according to European SCORE function underwent carotid ultrasonography. Carotid IMT and plaque assessment were performed using high-resolution B-mode ultrasonography. Participants with abnormal CIMT were reclassified to high CVR. RESULTS: According to SCORE function, 104 patients (32·5%) were of low CVR and 216 (67·5%) of intermediate CVR. Mean carotid IMT was 0·62 ± 0·13 mm, and carotid plaque was found in 35 (10·9%) patients. Carotid ultrasonography changed the risk stratum in 59 (18·4%) patients, who were reclassified to high CVR. Reclassification was more frequent in the intermediate CVR group than in the low CVR group (22·7% vs. 9·6%, P = 0·005) and was associated to age (P = 0·002), history of arterial hypertension (P < 0·001) and increased systolic blood pressure (P = 0·05). CONCLUSIONS: CIMT calculated by high-resolution B-mode ultrasonography could become an important tool in preventive medicine. Measuring CIMT may be useful in identifying asymptomatic individuals with subclinical atherosclerosis not detected by the actual CVR functions.

[Teaching sessions in primary care. Experience in health centres in an area of Madrid]. / Sesiones docentes en Atención Primaria. Experiencia en los centros de un Área de Madrid.

Those responsible for teaching of primary care teams of Area 7 of Madrid have noted a significant disparity in the organisation of teaching sessions. Therefore, the Madrid Area 7 Commission for Teaching and Research organised an idea-sharing day. This article aims to show the different organisational forms, model sessions, the benefits of education sessions, perceived problems and suggestions for improvement. Finally there is a decalogue, which can serve as a guide for organising teaching sessions in primary care.

EDUCORE project: a clinical trial, randomised by clusters, to assess the effect of a visual learning method on blood pressure control in the primary healthcare setting.

BACKGROUND: High blood pressure (HBP) is a major risk factor for cardiovascular disease (CVD). European hypertension and cardiology societies as well as expert committees on CVD prevention recommend stratifying cardiovascular risk using the SCORE method, the modification of lifestyles to prevent CVD, and achieving good control over risk factors. The EDUCORE (Education and Coronary Risk Evaluation) project aims to determine whether the use of a cardiovascular risk visual learning method--the EDUCORE method--is more effective than normal clinical practice in improving the control of blood pressure within one year in patients with poorly controlled hypertension but no background of CVD; METHODS/DESIGN: This work describes a protocol for a clinical trial, randomised by clusters and involving 22 primary healthcare clinics, to test the effectiveness of the EDUCORE method. The number of patients required was 736, all between 40 and 65 years of age (n = 368 in the EDUCORE and control groups), all of whom had been diagnosed with HBP at least one year ago, and all of whom had poorly controlled hypertension (systolic blood pressure >or= 140 mmHg and/or diastolic >or= 90 mmHg). All personnel taking part were explained the trial and trained in its methodology. The EDUCORE method contemplates the visualisation of low risk SCORE scores using images embodying different stages of a high risk action, plus the receipt of a pamphlet explaining how to better maintain cardiac health. The main outcome variable was the control of blood pressure; secondary outcome variables included the SCORE score, therapeutic compliance, quality of life, and total cholesterol level. All outcome variables were measured at the beginning of the experimental period and again at 6 and 12 months. Information on sex, age, educational level, physical activity, body mass index, consumption of medications, change of treatment and blood analysis results was also recorded; DISCUSSION: The EDUCORE method could provide a simple, inexpensive means of improving blood pressure control, and perhaps other health problems, in the primary healthcare setting; TRIAL REGISTRATION: The trial was registered with ClinicalTrials.gov, number NCT01155973 [http://ClinicalTrials.gov].

Oral versus intramuscular administration of vitamin B12 for vitamin B12 deficiency in primary care: a pragmatic, randomised, non-inferiority clinical trial (OB12).

OBJECTIVES: To compare the effectiveness of oral versus intramuscular (IM) vitamin B12 (VB12) in patients aged ≥65 years with VB12 deficiency. DESIGN: Pragmatic, randomised, non-inferiority, multicentre trial in 22 primary healthcare centres in Madrid (Spain). PARTICIPANTS: 283 patients ≥65 years with VB12 deficiency were randomly assigned to oral (n=140) or IM (n=143) treatment arm. INTERVENTIONS: The IM arm received 1 mg VB12 on alternate days in weeks 1-2, 1 mg/week in weeks 3-8 and 1 mg/month in weeks 9-52. The oral arm received 1 mg/day in weeks 1-8 and 1 mg/week in weeks 9-52. MAIN OUTCOMES: Serum VB12 concentration normalisation (≥211 pg/mL) at 8, 26 and 52 weeks. Non-inferiority would be declared if the difference between arms is 10% or less. Secondary outcomes included symptoms, adverse events, adherence to treatment, quality of life, patient preferences and satisfaction. RESULTS: The follow-up period (52 weeks) was completed by 229 patients (80.9%). At week 8, the percentage of patients in each arm who achieved normal B12 levels was well above 90%; the differences in this percentage between the oral and IM arm were -0.7% (133 out of 135 vs 129 out of 130; 95% CI: -3.2 to 1.8; p>0.999) by per-protocol (PPT) analysis and 4.8% (133 out of 140 vs 129 out of 143; 95% CI: -1.3 to 10.9; p=0.124) by intention-to-treat (ITT) analysis. At week 52, the percentage of patients who achieved normal B12 levels was 73.6% in the oral arm and 80.4% in the IM arm; these differences were -6.3% (103 out of 112 vs 115 out of 117; 95% CI: -11.9 to -0.1; p=0.025) and -6.8% (103 out of 140 vs 115 out of 143; 95% CI: -16.6 to 2.9; p=0.171), respectively. Factors affecting the success rate at week 52 were age, OR=0.95 (95% CI: 0.91 to 0.99) and having reached VB12 levels ≥281 pg/mL at week 8, OR=8.1 (95% CI: 2.4 to 27.3). Under a Bayesian framework, non-inferiority probabilities (Δ>-10%) at week 52 were 0.036 (PPT) and 0.060 (ITT). Quality of life and adverse effects were comparable across groups. 83.4% of patients preferred the oral route. CONCLUSIONS: Oral administration was no less effective than IM administration at 8 weeks. Although differences were found between administration routes at week 52, the probability that the differences were below the non-inferiority threshold was very low. TRIAL REGISTRATION NUMBERS: NCT01476007; EUDRACT (2010-024129-20).

Effectiveness and cost-effectiveness of a virtual community of practice to improve the empowerment of patients with ischaemic heart disease: study protocol of a randomised controlled trial.

INTRODUCTION: Virtual Communities of Practice (VCoP) or knowledge-sharing virtual communities offer ubiquitous access to information and exchange possibilities for people in similar situations, which might be especially valuable for the self-management of patients with chronic diseases. In view of the scarce evidence on the clinical and economic impact of these interventions on chronic conditions, we aim to evaluate the effectiveness and cost-effectiveness of a VCoP in the improvement of the activation and other patient empowerment measures in patients with ischaemic heart disease (IHD). METHODS AND ANALYSIS: A pragmatic randomised controlled trial will be performed in Catalonia, Madrid and Canary Islands, Spain. Two hundred and fifty patients with a recent diagnosis of IHD attending the participating centres will be selected and randomised to the intervention or control group. The intervention group will be offered participation for 12 months in a VCoP based on a gamified web 2.0 platform where there is interaction with other patients and a multidisciplinary professional team. Intervention and control groups will receive usual care. The primary outcome will be measured with the Patient Activation Measure questionnaire at baseline, 6, 12 and 18 months. Secondary outcomes will include: clinical variables; knowledge (Questionnaire of Cardiovascular Risk Factors), attitudes (Self-efficacy Managing Chronic Disease Scale), adherence to the Mediterranean diet (Mediterranean Diet Questionnaire), level of physical activity (International Physical Activity Questionnaire), depression (Patient Health Questionnaire), anxiety (Hospital Anxiety Scale-A), medication adherence (Adherence to Refill Medication Scale), quality of life (EQ-5D-5L) and health resources use. Data will be collected from self-reported questionnaires and electronic medical records. ETHICS AND DISSEMINATION: The trial was approved by Clinical Research Ethics Committee of Gregorio Marañón University Hospital in Madrid, Nuestra Señora de Candelaria University Hospital in Santa Cruz de Tenerife and IDIAP Jordi Gol in Barcelona. The results will be disseminated through workshops, policy briefs, peer-reviewed publications, local/international conferences. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT03959631).

A primary healthcare information intervention for communicating cardiovascular risk to patients with poorly controlled hypertension: The Education and Coronary Risk Evaluation (Educore) study-A pragmatic, cluster-randomized trial.

PURPOSE: Uncertainty exists regarding the best way to communicate cardiovascular risk (CVR) to patients, and it is unclear whether the comprehension and perception of CVR varies according to the format used. The aim of the present work was to determine whether a strategy designed for communicating CVR information to patients with poorly controlled high blood pressure (HBP), but with no background of cardiovascular disease, was more effective than usual care in the control of blood pressure (BP) over the course of a year. METHODS: A pragmatic, two-arm, cluster-randomized controlled trial was performed. Consecutive patients aged 40-65 years, all diagnosed with HBP in the last 12 months, and all of whom showed poor control of their condition (systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg), were recruited at 22 primary healthcare centres. Eleven centres were randomly assigned to the usual care arm, and 11 to the informative intervention arm (Educore arm). At the start of the study, the Educore arm subjects were shown the "low risk SCORE table", along with impacting images and information pamphlets encouraging the maintenance of good cardiovascular health. The main outcome variable measured was the control of HBP; the secondary outcome variables were SCORE table score, total plasma cholesterol concentration, use of tobacco, adherence to prescribed treatment, and quality of life. RESULTS: The study participants were 411 patients (185 in the Educore arm and 226 in the usual care arm). Multilevel logistic regression showed that, at 12 months, the Educore intervention achieved better control of HBP (OR = 1.57; 1.02 to 2.41). No statistically significant differences were seen between the two arms at 12 months with respect to the secondary outcomes. CONCLUSIONS: Compared to usual care, the Educore intervention was associated with better control of HBP after adjusting for age, baseline SBP and plasma cholesterol, at 12 months.

[Opinion and Participation in the Regional Early Breast Cancer Detection Program in 2007 on the part of family physicians from a health district in the Autonomous Community of Madrid, Spain]. / Opinión y participación de los médicos de familia de la Comunidad de Madrid en el Programa Regional de Detección Precoz de Cáncer de Mama en 2007.

BACKGROUND: Mammogram screening is the most effective method for the early detection of breast cancer. The objective of this study is to evaluate the degree of knowledge, the opinion and the participation in the early breast cancer detection program on the part of the family physicians of the Autonomous Community of Madrid. METHODS: The population studied was comprised of family physicians from Madrid Health District Seven. An anonymous, self-administered questionnaire comprised of 30 questions grouped into physicians characteristics and opinion concerning the early breast cancer detection programs. RESULTS: A total of 46% of the physicians replied. A total of 94% of the physicians believed that it is their duty to inform their patients concerning preventive activities, including breast cancer screening, and 95% believed their advice to be useful for convincing women to have a mammogram. A total of 72% believed information to be lacking on this program. During the time when mammograms are being taken at their centres, 24% of the physicians surveyed always or almost always ask the women if they have any doubts or would like further information, 43% having set up appointments for them and 95% advising them to have a mammogram taken. CONCLUSIONS: The family physicians have a good opinion of the early breast cancer detection program and feel their advice to be effective for improving the participation in the program. They report lack of information and inform women about the program to only a small degree.

[A Comparison of Methods for Modeling Factors Associated with Hospital Admissions in Incident Cases of Heart Failure]. / Comparación de métodos para modelizar los factores asociados con los ingresos hospitalarios en casos incidentes de insuficiencia cardíaca.

OBJECTIVE: Heart failure (HF) is an important public health problem due to its increasing prevalence, and the decompensation associated with hospital admission represents an increased risk of death. The objective of this study was to compare several methods to model the variable hospitalizations and to determine the effect of factors associated with hospital admissions in incident cases of HF. METHODS: Study of a retrospective cohort of patients with information extracted from electronic medical records of PC was performed. Patients 24 year and older with at least 1 visit to PC in 2006 were included. Registered hospital admissions of HF incident cases between 2006 and 2010 or until death were analyzed and comparison of Poisson, Negative Binomial (NB), zero-inflated and Hurdle regression models were conducted to identify factors associated con hospitalizations. RESULTS: 3,061 patients were identified in a cohort of 227,984. Regarding the factors associated with hospitalizations and according to the zero inflated NB regression model, patients who presented valvular disease (OR=2.01; CI95% 1.22-3.30), or were being treated with antithrombotics (OR=3.45; CI95%: 1.61-7.42) or diuretics (OR=2.28; CI95% 1.13-4.58) had a lower likelihood of hospitalization. Factors associated with a higher rate of hospital admissions were having valvular disease (IRR=1.37; CI95% 1.03-1.81) or diabetes (IRR=1.38; 1.07-1.78), and being treated with calcium antagonists (IRR=1.35; CI95% 1.05- 1.73) or ACE inhibitors (IRR=1.43; CI95% 1.06- 1.92). Having being referred to a cardiologist had a protective effect (IRR=0.86; CI95% 0.76- 0.97). CONCLUSIONS: The regression model that obtained the best adjustment was the zero inflated NB. According to this model, the factors associated with an increase in hospital admissions were valvulopathies, diabetes and treatment with calcium antagonists.

OBJETIVO: La insuficiencia cardiaca (IC) es un importante problema de salud pública debido a su creciente prevalencia y la descompensación que conlleva un ingreso hospitalario representa un aumento del riesgo de muerte. El objetivo de este trabajo fue comparar varios métodos para modelizar la variable hospitalizaciones y determinar el efecto de los factores asociados con los ingresos hospitalarios en casos incidentes de IC. METODOS: Se realizó un estudio de cohortes restrospectivo con información extraída de la historia clínica electrónica de Atención Primaria (AP). Se incluyeron pacientes mayores de 24 años que habían realizado al menos 1 consulta en AP durante el año 2006. Se analizaron las hospitalizaciones registradas de casos incidentes de IC entre 2006 y 2010 o hasta su fallecimiento y se compararon modelos de regresión de Poisson, Binomial Negativa (BN), inflados con ceros y de Hurdle para identificar factores asociados a las hospitalizaciones. RESULTADOS: Se identificó a 3.061 personas con IC en una cohorte de 227.984 pacientes. Respecto a los factores asociados con las hospitalizaciones y según el modelo de regresión BN inflado con ceros, los pacientes con valvulopatías (OR=2,01; IC95%: 1,22-3,30) o en tratamiento con antitrombóticos (OR=3,45; IC95%: 1,61-7,42) o diuréticos (OR=2,28; IC95%:1,13-4,58) tuvieron mayor probabilidad de hospitalización. Los factores asociados a una mayor tasa de ingresos fueron tener valvulopatías (IRR=1,37; IC95%: 1,03-1,81) o diabetes mellitus (IRR=1,38, 1,07-1,78) y estar en tratamiento con calcioantagonistas (IRR=1,35; IC95%: 1,05-1,73) o IECAS (IRR=1,43; IC95%:1,06-1,92). Haber tenido derivaciones a cardiología tuvo efecto protector (IRR=0,86; IC95%: 0,76-0,97). CONCLUSIONES: El modelo de regresión que tiene mejor ajuste es el BN inflado con ceros. Según este modelo los factores asociados con un incremento en los ingresos hospitalarios son las valvulopatías, la diabetes mellitus y el tratamiento con calcioantagonistas.

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.
