Multicausal analysis of mortality due to diabetes mellitus in Spain, 2016-2018

OBJECTIVES

This study aimed to assess multicausal mortality due to diabetes from 2016-2018 in Spain. Specific objectives were to quantify the occurrence of diabetes as an underlying cause or as any registered cause on the death certificate.

MATERIALS AND METHODS

A cross-sectional descriptive study taking a multicausal approach.

RESULTS

Diabetes appears as an underlying cause of 2.3% of total deaths in Spain, and as any cause in 6.2%. In patients in whom Diabetes appears as an underlying cause on the death certificates, the 15 most frequent immediate causes are cardiovascular diseases in men(prevalence ratio 1,59)and women (PR1,31). In men, the causes associated with diabetes as any cause were skin diseases(prevalence ratio 1.33), followed by endocrine diseases(prevalence ratio 1.26)and genitourinary diseases (prevalence ratio1.14). In women, the causes associated with the presence of diabetes as any cause were endocrine (prevalence ratio 1.13)and genitourinary (prevalence ratio 1.04)diseases.

CONCLUSIONS

In patients in whom diabetes appears as an underlying cause on the death certificates, the 15 most frequent immediate causes are cardiovascular diseases. In men, the causes associated with the presence of diabetes as any cause of death are skin, endocrine and genitourinary diseases. In women, the causes associated with diabetes as any cause are endocrine and genitourinary.

Design and validation of a new questionnaire with a gender perspective to measure medication adherence for secondary prevention of ischaemic heart disease: study protocol

INTRODUCTION AND OBJECTIVES

Only about 50% of chronic patients in high-income countries adhere to their treatment. There are methods to measure medication adherence but none of them can be considered optimal. This study will aim to design and validate a questionnaire to measure medication adherence in patients with ischaemic heart disease using a direct method as a gold-standard adherence measure and taking into account the gender perspective. Moreover, the profile of low adherence in these patients will be determined.

METHODS AND ANALYSIS

First study phase consists on the questionnaire design following the next steps: identification of the dimensions, definition of the target population, questionnaire items and order, response coding, questionnaire instructions, content validity by experts and understandability. In the second phase, a cross-sectional study will be performed to end the questionnaire development and validate it. Four hundred and forty patients (50% female) with acute coronary syndrome receiving treatment within the previous 12 months will be included. Patient will answer the initial questionnaire and adherence to aspirin and statin will be measured using a direct method (drug concentration analysis in blood) and other questionnaires. From the set of preselected questionnaire items, those most closely associated with the gold standard measure will be selected using multivariate statistics.

ETHICS AND DISSEMINATION

All participants gave their written informed consent before participating in the study. The study protocol follows the recommendations of the Declaration of Helsinki and was approved by the ethics committees of the three participating centres. The results of this study will be displayed at national and international conferences and in peer-reviewed scientific journals.

Diabetes mellitus as a cause of premature death in small areas of Spain by socioeconomic level from 2016 to 2020: A multiple-cause approach

OBJECTIVE

This study aimed to assess premature mortality due to Diabetes in small areas of Spain between 2016 and 2020, and its relationship with socioeconomic level and the immediate cause of death. As a secondary objective, we evaluated the effect of the Covid 19 pandemic.

METHODS

This was an ecological study of premature mortality due to Diabetes from 2016 to 2020, with a focus on small areas. All deaths in people under 75 years of age due to Diabetes as the underlying cause were included RESULTS: The final sample comprised 7382 premature deaths in 5967 census tracts. Women living in census tracts with an high level of deprivation(RR=2.40) were at a significantly higher risk. Mortality from Diabetes increased with deprivation, especially people aged 0-54(RR=2.40). People with an immediate cause of death related to a circulatory disease, living in census tracts with an high level of deprivation(RR=3.86) was associated with a significantly greater risk of death with underlying Diabetes. When a disease of the circulatory system was recorded as the immediate cause of death, being 65-74 years (RR=71.01) was associated with a significantly higher risk of premature mortality.

CONCLUSIONS

Living in geographic areas with higher levels of socioeconomic deprivation is associated with a higher risk of premature death from Diabetes in Spain. This relationship has a greater impact on women, people under 54 years, and people at risk of death caused directly by diseases of the circulatory system. Premature mortality due to diabetes saw a modest increase in 2020.

[Predictive validity of Clinical Risk Groups in chronic patients in primary healthcare]

OBJECTIVE

To analyse a prediction model for admissions and hospital emergencies based on Clinical Risk Groups, in a population of complex chronic patients demanding primary care.

DESIGN

A multicentric retrospective observational study, of a cohort of chronic patients with comorbidity, from January until December 2013.

PLACE

The study population was assigned to the Santa Pola and Raval health centres from the Health Department of Elche.

PARTICIPANTS

Cohort of chronic patients with comorbidity, from January to December 2013.

INTERVENTIONS

Data about the number of admissions, reasons and complexity level associated with the admission were collected by the review of medical records.

MAIN MEASURES

To determine the level of complexity, the classification included in the chronicity strategy of the Valencian Community based on Clinical Risk Groups was used.

RESULTS

Five hundred and four patients were recruited with a high complexity degree (N3) and 272 with moderate/low complexity (N1-N2). A higher comorbidity was observed in N3 patients with high complexity [Charlson 2.9 (DE 1.8) vs. 1.9 (DE 1.3); P<.001], and higher dependence degree for basic diary activities [Barthel 16.1 (n=81) vs. 7.3 (n=20); P<.001]. Association between the number of admissions [0.4 (DE 0.8) vs. 0.1 (DE 0.5); P<.001] and emergency visits [0.8 (DE 1.5) vs. 0.3 (DE 0.8), P<.001] was significatively higher in patients from N3 group than N1-N2 groups.

CONCLUSIONS

The predictive capacity of CRG grouper showed high sensibility for the patient classification with a high degree of complexity. Its specificity and positive predictive value were lower for the association of the N3 complexity stratum.

Association of Visiting the Physiotherapist with Mortality in the Spanish General Population: A Population-Based Cohort Study

Background and Objectives: The purpose of this retrospective population-based cohort study was to analyse the association between attendance of physiotherapy with mortality in the Spanish general population and describe the profile of people who do not visit a physiotherapist in Spain. Material and Methods: The data sources were the 2011/2012 National Health Survey (ENSE11) and the national database of death in Spain, and the participants were all adult respondents in the ENSE11. Results: Of 20,397 people, 1101 (5.4%) visited the physiotherapist the previous year, and the cumulative incidence of total mortality was 5.4% (n = 1107) at a mean follow-up of 6.2 years. Visiting the physiotherapist was associated with lower all-cause mortality in the population residing in Spain, quantified at 30.1% [RR = 0.699; 95% CI (0.528-0.927); p = 0.013]. The factors associated with not visiting a physiotherapist were the following: rating one's health as good (9.8%; n = 1017; p < 0.001), not having any hospital admission in the previous year (9.6%; n = 1788; p < 0.001), not having visited the general practitioner in the previous month (9.6%; n = 1408; p < 0.001), and not having attended a day hospital in the previous year (9.7%; n = 1836; p < 0.001). Conclusions: Visiting a physiotherapist was associated with a lower mortality from all causes in the population living in Spain.

Epidemiological study on gender bias and low-value practices in primary care: a study protocol

INTRODUCTION

Evidence shows that gender has a substantial impact on health behaviours, access to and use of health systems and health system responses. This study aims to assess gender bias in patients subjected to low-value practices in the primary care setting and to develop recommendations for reducing adverse events that women experience for this reason.

METHODS AND ANALYSIS

A Delphi study will be performed to reach a consensus on the 'Do Not Do' recommendations with a possible gender bias. A retrospective cohort study in a random selection of medical records will then be carried out to identify the frequency of adverse events that occur when the selected 'Do Not Do' recommendations are ignored. Qualitative research techniques (consensus conference and nominal group) will be carried out to develop recommendations to address any gender bias detected, considering barriers and facilitators in clinical practice.

ETHICS AND DISSEMINATION

The study was approved by the ethics committee of San Juan de Alicante Hospital (San Juan de Alicante, Spain) Reference N. 21/061. We will disseminate the research findings via peer-reviewed articles, presentations at national and international scientific forums and webinars.

TRIAL REGISTRATION NUMBER

The study was registered at ClinicalTrials.gov (NCT05233852) on 10 February 2022.

[Factors associated with dissatisfaction with pharmacological treatment in patients with type 2 diabetes mellitus: A cross-sectional study]

BACKGROUND AND OBJECTIVES

Diabetes is a chronic disease with a high impact on both health and Quality of Life Related to Health (QLRH). To evaluate the satisfaction of treatment in patients with type 2 diabetes mellitus through the Diabetes Treatment Satisfaction Questionnaire (DTSQ) and its relationship with sociodemographic variables, with antidiabetic medication and clinical-analytical variables.

MATERIALS AND METHODS

This cross-sectional study was conducted in General University Hospital of San Juan de Alicante between September 2016 and December 2017. Two hundred thirty-two patients diagnosed with type 2 diabetes mellitus at least 1 year before inclusion, treated with antidiabetic medication were included. The Spanish version of the DTSQ scale was used to measure satisfaction with treatment. Factors associated with low satisfaction were analyzed by applying the Chi-square test for qualitative variables and Student-T for quantitative variables. To estimate magnitudes of association, logistic models were adjusted.

RESULTS

Two hundred thirty-two patients were included in this study. 21.5% of the patients presented low satisfaction with the treatment. Patients who presented low satisfaction with treatment were associated with medications that could cause hypoglycemia (OR: 2.872 [1.195-6.903]), HbA1c levels higher than 7% (OR: 2.260 [1.005-5.083]) and drugs administered by the route oral (OR: 2.749 [1.233-6.131]).

CONCLUSIONS

Patients with type 2 diabetes mellitus who had a lower score on the DTSQ questionnaire were associated with medications that produced hypoglycaemia, and with higher levels of HbA1c higher than 7%, and those who took oral medication.

Trends in premature mortality from diabetes mellitus in Costa Rica in the period 2000-2020

OBJECTIVES

To analyze the temporal trends of premature mortality from diabetes in Costa Rica in the period 2000-2020, at a national level and by province, and the effect of the COVID-19 pandemic on diabetes mortality during the year 2020.

METHODS

We studied the temporal trends of mortality from diabetes in Costa Rica in the period between 2000 and 2020. Age-standardized mortality rates and corresponding 95% confidence intervals were calculated for each year, sex and province.

RESULTS

We analyzed the data of 17,968 deceased persons. The mean age was 72.5 years (range 1 to 109 years), and 51.5% of the population (n = 9253) was younger than 75 years. In both men and women, we observed a significant decrease in mortality from 2000 to 2014, followed by the opposite trend from 2014 to 2020, with average yearly increases of 13.9% in men and 11.6% in women.

CONCLUSIONS

Premature mortality from diabetes has been growing from 2014. The COVID-19 pandemic changed the mortality pattern, increasing premature diabetes deaths in Costa Rica in 2020.

Psychometric properties of the Clarke questionnaire for hypoglycemia awareness in the Spanish population with type 2 diabetes

OBJECTIVES

The Clarke questionnaire, validated in Spanish language, assesses hypoglycemia awareness in patients with type 1 diabetes. This study aimed to analyze its psychometric properties in patients with type 2 diabetes (T2DM).

METHODS

This was a questionnaire validation study. Patients with T2DM and treated with insulin, sulfonylureas or glinides were consecutively recruited from six endocrinology consultations and six primary care centers. The internal structure of the 8-item Clarke questionnaire was analyzed by exploratory (training sample) and confirmatory (testing sample) factor analysis; the internal consistency using Omega's McDonald coefficient; and goodness of fit with comparative fit index (CFI, cutoff >0.9), Goodness of Fit Index (GFI, cutoff >0.9), and root mean-square error of approximation (RMSEA, cutoff <0.09), as well as unidimensionality indicators.

RESULTS

The 265 participants (56.8% men) had a mean age of 67.8 years. Confirmatory factor analysis for one dimension obtained poor indicators: fit test (p < 0.001); CFI = 0.748; RMSEA = 0.122 and SRMR = 0.134. Exploratory factor analysis showed 2 or 3 dimensions with poor adjustment indicators. Omega's McDonald was 0.739.

CONCLUSIONS

The Spanish version of the Clarke questionnaire was not valid or reliable for assessing hypoglycemia awareness in people with T2DM in Spanish population.

Factors Associated with Colorectal Cancer Screening in Spain: Results of the 2017 National Health Survey

This study aimed to determine the CRC screening coverage of people aged between 50 and 69 years who were living in Spain in 2017 and describe the factors associated with not having had a faecal occult blood test (FOBT). A cross-sectional study was performed using data from the Spanish National Health Survey 2017. We analysed 7568 individuals between the ages of 50 and 69 years. The proportion of respondents between 50 and 69 years old who had had an FOBT was 29.0% (n = 2191). The three autonomous communities with the lowest proportion of respondents who had had an FOBT were Extremadura (8.7%, n = 16), Ceuta-Melilla (10.4%, n = 3), and Andalucia (14.1%, n = 186). The variables associated with not having had an FOBT were being 50-54 years old (PR = 1.09; 95% CI 1.04-1.14), having been born outside of Spain (PR = 1.11; 95% CI 1.06-1.16), not having been vaccinated against the flu (PR = 1.09; 95% CI 1.04-1.15), never having had a colonoscopy (PR = 1.49; 95% CI 1.40-1.59), not having had an ultrasound scan in the last year (PR = 1.09; 95% CI 1.04-1.14), and not having seen a primary care physician in the last month (PR = 1.08; 95% CI 1.04-1.12). The factors associated with not getting an FOBT were young age, having been born outside of Spain, not having been vaccinated against the flu in the last campaign, and not making frequent use of healthcare services.

Early Detection of Atrial Fibrillation in Community Pharmacies-CRIFAFARMA Study

BACKGROUND

Atrial fibrillation (AF) is the most common arrhythmia to appear in clinical practice. People with AF have 5 times the risk of stroke compared to the general population.

OBJECTIVE

This study aimed to determine the prevalence of AF in people over the age of 50 without known AF, who presented to a community pharmacy to check their cardiovascular risk factors, to identify risk factors associated with AF, and to assess the risk of stroke in people who screened positive for AF.

METHODS

A multicenter observational descriptive study of a screening program took place from May to December 2016. A blood pressure monitor (Microlife Watch BP Home) was used to screen for AF, and the CHA2DS2-VASc questionnaire was used to assess stroke risk.

RESULTS

The study included 452 adults over the age of 50. The CRIFAFARMA study detected a prevalence of AF of 9.1%. Risk factors for AF were: age of 75 years or older (P = .024), lack of physical activity (P = .043), diabetes (P < .001), dyslipidemia (P = .003), and history of cardiovascular disease (P = .003). Diabetes (OR 2.79, P = .005) and dyslipidemia (OR 2.16, P = .031) had a combined explanatory capacity in the multivariable logistic regression model adjusted for age. 85% were at high risk of stroke according to the CHA2DS2-VASc scale.

CONCLUSIONS

AF was detected in more than 9% of the included population. Factors associated with AF were advanced age, lack of physical activity, diabetes, dyslipidemia, and history of cardiovascular disease, with diabetes and dyslipidemia standing out as the factors with independent explanatory capacity.

Barriers and Solutions to Improve Therapeutic Adherence from the Perspective of Primary Care and Hospital-Based Physicians

PURPOSE

To identify the barriers affecting treatment adherence in patients with chronic disease and to determine solutions through the physician's opinion of primary care and hospital settings.

METHODS

An observational study using the nominal group technique was performed to reach a consensus from experts. A structured face-to-face group discussion was carried out with physicians with more than 10 years of experience in the subject of treatment adherence/compliance in either the primary care setting or the hospital setting. The experts individually rated a list of questions using the Likert scale and prioritized the top 10 questions to identify barriers and seek solutions afterward. The top 10 questions that obtained the maximum score for both groups of experts were prioritized. During the final discussion group, participating experts analyzed the prioritized items and debated on each problem to reach consensual solutions for improvement.

RESULTS

A total of 17 professionals experts participated in the study, nine of them were from a primary care setting. In the expert group from the primary care setting, the proposed solution for the barrier identified as the highest priority was to simplify treatments, measure adherence and review medication. In the expert group from the hospital setting, the proposed solution for the barrier identified as the highest priority was training on motivational clinical interviews for healthcare workers undergraduate and postgraduate education. Finally, the expert participants proposed implementing an improvement plan with eight key ideas.

CONCLUSION

A consensual improvement plan to facilitate the control of therapeutic adherence in patients with chronic disease was developed, taking into account expert physicians' opinions from primary care and hospital settings about barriers and solutions to address therapeutic adherence in patients with chronic disease.

[Analysis of two health attendance models for the non-hospital emergencies in Gipuzkoa: Retrospective study]

BACKGROUND AND OBJECTIVE

Out-of-hospital medical emergency services are defined as a functional organization that performs a set of sequential human and material activities. The objective of this study was to compare the mortality of patients attended by the out-of-hospital medical emergency services in 2 neighboring Spanish regions with different models of healthcare transport assistance for emergency care.

MATERIAL AND METHOD

Retrospective observational cohort study, done between June 1, 2007 and December 31, 2008 in 2 regions of Gipuzkoa, Alto Deba (AD) and Bajo Deba (BD). The study variables were age, sex and place of exposure (AD/BD), heart rate, blood pressure, initial reason for the call defined by the European Resuscitation Council, unconsciousness and digestive bleeding. 3452 subjects were analyzed.

RESULTS

The risk of in situ mortality in BD was 1.31 times higher than in AD (P=.050), that of hospital mortality in BD was 0.71 times lower than in AD (P=.011) and the risk of mortality at one year between counties and the combined mortality (in situ+hospital) did not contribute significant differences.

CONCLUSIONS

Mortality (in situ+in-hospital, and one year aftercare) of patients treated by the out-of-hospital emergency medical services in AD (non-medicalized healthcare transport model) was similar to that of the BD region (mixed healthcare transport model).

Evolutionary Analysis of International Scientific Output in Occupational Therapy from 1917 to 2020

Published evidence on the progress of occupational therapy research from a broad perspective is limited. The purpose of this study was to analyze the international research productivity on occupational therapy from 1917 to 2020. This was a bibliometric study including articles indexed on MEDLINE, Scopus, and CINAHL. The literature search was conducted in June 2021 using the descriptor “occupational therapy” and the term “Ergotherap*”, and was limited to citable documents. Price’s law and Bradford’s law were applied to analyze a number of bibliometric indicators. Research on occupational therapy had an average annual growth rate of 26.4% and followed an exponential model. The top producing countries were the USA (21.52%) and the UK (6.07%). There is a high transience index of 74.81%. The top producing author was Kielhofner, G. (n = 132). Studies with the highest reported scientific evidence accounted for 1.13% (n = 638) of the total number of publications. More randomized controlled trials are necessary to increase the quality of the evidence base. Moreover, a greater collaboration between authors is needed for the professionalization of this research field.

A modified Delphi consensus study to identify improvement proposals for COPD management amongst clinicians and administrators in Spain

AIMS

To identify the obstacles hindering the appropriate management of chronic obstructive pulmonary disease (COPD) in Spain based on consensus amongst clinicians and administrators.

METHODS

A two-round modified Delphi questionnaire was sent to clinicians (pulmonologists and GPs) and administrators, all experts in COPD. The scientific committee developed the statements and selected the participating experts. Four areas were explored: diagnosis, training, treatment, and clinical management. Panellists' agreement was assessed using a 9-point Likert scale, with scores of 1 to 3 indicating disagreement and 7 to 9, agreement. Consensus was considered to exist when 70% of the participants agreed or disagreed with the statement.

RESULTS

Respective response rates for the first and second round were 68% and 91% for clinicians, and 60% and 100% for administrators. The statements attracting the highest degree of consensus were: "Not enough nursing resources (time, staff, duties) are allocated for performing spirometry" (85.3% clinicians; 75% administrators); "Nurses need specific training in COPD" (84.8% clinicians; 100% administrators); "Rehabilitation programs are necessary for treating patients with COPD" (94.1% clinicians; 91.7% administrators); and "Integrated care processes facilitate the deployment of educational programs on COPD" (79.4% clinicians; 83.3% administrators).

CONCLUSIONS

This document can inform the development and implementation of specific initiatives addressing the existing obstacles in COPD management.

WHAT'S KNOWN

COPD is a prevalent and underdiagnosed disease that causes substantial morbidity and mortality. The National COPD Strategy established objectives and work programmes to apply in Spain. There are barriers impeding the application of interventions contemplated in the COPD strategy.

WHAT'S NEW

Different agents involved in COPD management agree that the main challenges to improve COPD management are resource shortages in primary care nursing and lack of training in the use of COPD clinical guidelines. Clinicians and administrators involved in COPD management support the implementation of urgent measures to tackle the underdiagnosis of COPD, especially in primary care, along with the routine inclusion of respiratory rehabilitation programmes for COPD.

Renal function and attributable risk of death and cardiovascular hospitalization in participants with diabetes from a registry-based cohort

AIMS

To estimate the attributable risk of renal function on all-cause mortality and cardiovascular hospitalization in patients with diabetes.

METHODS

A prospective cohort study in 19,469 adults with diabetes, free of cardiovascular disease, attending primary care in Spain (2008-2011). The estimated glomerular filtration rate (eGFR) and other variables were collected and patients were followed to the first hospitalization for coronary or stroke event, or death, until the end of 2012. The cumulative incidence of the study endpoints by eGFR categories was graphically displayed and adjusted population attributable risks (PARs) for low eGFR was calculated.

RESULTS

Mean follow-up was 3.2 years and 506 deaths and 1720 hospitalizations were recorded. The cumulative risk for the individual events increased as eGFR levels decreased. The PAR associated with having an eGFR of 60mL/min/1.73m² or less was 11.4% (95% CI 4.8-18.3) for all-cause mortality, 9.2% (95% CI 5.3-13.4) for coronary heart disease, and 2.6% (95% CI -1.8 to 7.4) for stroke.

CONCLUSIONS

Reduced eGFR levels were associated with a larger proportion of avoidable deaths and cardiovascular hospitalizations in people with diabetes compared to previously reported results in people with other cardiovascular risk factors.

Hospital admissions trends for severe hypoglycemia in diabetes patients in Spain, 2005 to 2015

AIMS

To analyze hospital admissions trends, inpatient mortality, and mean length of hospital stay due to hypoglycemia in patients with diabetes in Spain from 2005 to 2015.

METHODS

National Institute of Statistics provided information on hospital discharge and mortality. Hospital admissions due to severe hypoglycemia were identified using ICD-9 codes. Age-adjusted admission and mortality rates were stratified by sex and year. Joinpoint regression models were used to estimate trends.

RESULTS

Admissions rates per 100,000 population were higher for men than women in 2005 (30.2, 95%CI:29.3, 31.0 versus 21.5, 95%CI:20.9, 22.1) and 2015 (23.7, 95%CI:23.0, 24.4 versus 13.2, 95%CI:12.7, 13.6). Mortality per 100,000 population was also higher for men in both years (2005: 9.4, 95%CI:7.8, 11.0 versus 8.6, 95%CI:7.4, 9.8; 2015: 6.4, 95%CI:5.3, 7.6 versus 4.1, 95%CI:3.3, 4.8). Mortality dropped 5.2 percentage points annually (95%CI:-8.4, -1.9) in men and 7.0 percentage points annually (95%CI:-8.7, -5.2) in women from 2005 to 2015. Mean length of hospital stay changed only for women: 7.8 days (95%CI:7.5, 8.0) to 6.7 days (95%CI:6.4, 6.9).

CONCLUSIONS

Hospital admissions and inpatient mortality due to hypoglycemia in diabetes patients decreased from 2005 to 2015. This trend was more pronounced in women. Mean length of hospital stay decreased in women.

Analysis of LDL and HDL size and number by nuclear magnetic resonance in a healthy working population: The LipoLab Study

BACKGROUND AND AIM

Atherosclerosis is the underlying process in cardiovascular disease (CVD), the first cause of death in developed countries. We aimed to identify people with no known CVD and normal values of LDL-C and HDL-C, but with alterations in the number and size of lipoprotein particles (as measured by nuclear magnetic resonance [NMR]) and to analyse their sociodemographic, clinical and biochemical characteristics.

METHODS

Cross-sectional study in occupational risks prevention centre in Castellón (Spain) in 2017 and 2018, in consecutively recruited adults (18-65 years) with no known CVD. Sociodemographic, clinical and biochemical variables were collected. Lipid profiles were analysed (Liposcale test), along with the concentration, size and number of the main types of lipoprotein particles, determined by 2D diffusion-ordered NMR spectroscopy. Using contingency tables, we analysed the characteristics of people with normal LDL and HDL cholesterol but abnormal levels of LDL and HDL particles. The magnitude of association between explanatory variables and abnormal levels of each kind of lipoprotein was assessed with multivariable logistic regression models.

RESULTS

Of the 400 total participants (31.3% women; age 46.4 ± 4.3 years), 169 had normal LDL and HDL cholesterol. Abnormal lipoprotein particle values depended on the subtype: prevalence of abnormal LDL levels ranged from 8.3% to 36.7%; and of HDL, from 28.4% to 42.6%. High systolic blood pressure and total cholesterol were significantly associated with abnormal LDL levels. Male sex and high systolic blood pressure were associated with abnormalities in HDL.

CONCLUSIONS

An extended lipids profile, obtained by NMR, enables the identification of people with normal HDL-C and LDL-C levels who present abnormal levels of LDL-P and/or HDL-P. Higher total cholesterol, systolic blood pressure, BMI and male sex were significantly associated with these abnormal values.

The influence of hemoglobin A1c levels on cardiovascular events and all-cause mortality in people with diabetes over 70 years of age. A prospective study

AIM

Glycated hemoglobin A1c (HbA1c) is a reliable risk factor of cardiovascular diseases in diabetic patients, but information about this relationship in elderly patients is scarce. The aim of this study is to analyze, the relationship between HbA1c levels and the risk of mayor adverse cardiovascular events (MACE) in patients with diabetes over 70 years.

METHODS

Prospective study of subjects with diabetes using electronic health records from the universal public health system in the Valencian Community, Spain, 2008-2012. We included men and women aged≥70 years with diabetes who underwent routine health examinations in primary care. Primary endpoint was the incidence of MACE: all-cause mortality and/or hospital admission due to coronary heart disease or stroke. A standard Cox and Cox-Aalen models were adjusted.

RESULTS

5016 subjects were included whit a mean age of 75.1 years (46.7% men). During an average follow-up of 49 months (4.1 years), 807 (16.1%) MACE were recorded. The incidence of MACE was 20.6 per 1000-person-years. Variables significantly associated to the incidence of MACE were male gender (HR: 1.61), heart failure (HR: 2.26), antiplatelet therapy (HR: 1.39), oral antidiabetic treatment (HR: 0.74), antithrombotics (HR: 1.79), while age, creatinine, HbA1c and peripheral arterial disease were time-depend associated variables.

CONCLUSION

These results highlights the importance of HbA1c level in the incidence of cardiovascular events in older diabetic patients.

Machine learning to predict cardiovascular risk

AIMS

To analyse the predictive capacity of 15 machine learning methods for estimating cardiovascular risk in a cohort and to compare them with other risk scales.

METHODS

We calculated cardiovascular risk by means of 15 machine-learning methods and using the SCORE and REGICOR scales and in 38 527 patients in the Spanish ESCARVAL RISK cohort, with 5-year follow-up. We considered patients to be at high risk when the risk of a cardiovascular event was over 5% (according to SCORE and machine learning methods) or over 10% (using REGICOR). The area under the receiver operating curve (AUC) and the C-index were calculated, as well as the diagnostic accuracy rate, error rate, sensitivity, specificity, positive and negative predictive values, positive likelihood ratio, and number needed to treat to prevent a harmful outcome.

RESULTS

The method with the greatest predictive capacity was quadratic discriminant analysis, with an AUC of 0.7086, followed by Naive Bayes and neural networks, with AUCs of 0.7084 and 0.7042, respectively. REGICOR and SCORE ranked 11th and 12th, respectively, in predictive capacity, with AUCs of 0.63. Seven machine learning methods showed a 7% higher predictive capacity (AUC) as well as higher sensitivity and specificity than the REGICOR and SCORE scales.

CONCLUSIONS

Ten of the 15 machine learning methods tested have a better predictive capacity for cardiovascular events and better classification indicators than the SCORE and REGICOR risk assessment scales commonly used in clinical practice in Spain. Machine learning methods should be considered in the development of future cardiovascular risk scales.

Validation of the electronic prescription as a method for measuring treatment adherence in hypertension

OBJECTIVE

To validate electronic prescriptions (e-prescriptions) as a method for measuring treatment adherence in patients with hypertension.

METHODS

This prospective study initially included 120 patients treated for hypertension in primary care centers. Adherence was measured using the gold standard, the medication event monitoring system (MEMS), versus the index test, the e-prescription program, at baseline and at 6, 12, 18 and 24 months. We calculated the adherence rate using the MEMS and the medication possession ratio (MPR) for the e-prescriptions. We considered patients adherent if they had an adherence rate of 80% to 100%. To validate the e-prescription, we obtained measures of diagnostic accuracy, the Kappa concordance index, and the area under the ROC curve (AUC).

RESULTS

We included 102 patients. Overall adherence was 77.4% by MEMS (95%CI: 66.8-88) and 80.4% (95%CI: 70.3-90.5) by MPR. At 24 months, sensitivity was 87% and specificity, 93.7%. The AUC was 0.903 (95%CI: 0.817-0.989).

CONCLUSION

Measures of treatment adherence were not significantly different between e-prescription and gold standard at most visits, and the e-prescription showed good discriminatory diagnostic capacity.

PRACTICE IMPLICATIONS

If patients are included in an e-prescription program for at least 2 years, e-prescription is an inexpensive method to measure adherence in hypertension.

Waning protection of influenza vaccination during four influenza seasons, 2011/2012 to 2014/2015

BACKGROUND

Concerns have been raised about intraseasonal waning of the protection conferred by influenza vaccination.

METHODS

During four influenza seasons, we consecutively recruited individuals aged 18years or older who had received seasonal influenza vaccine and were subsequently admitted to the hospital for influenza infection, asassessed by reverse transcription polymerase chain reaction. We estimated the adjusted odds ratio (aOR) of influenza infection by date of vaccination, defined by tertiles, as early, intermediate or late vaccination. We used a test-negative approach with early vaccination as reference to estimate the aOR of hospital admission with influenza among late vaccinees. We conducted sensitivity analyses by means of conditional logistic regression, Cox proportional hazards regression, and using days between vaccination and hospital admission rather than vaccination date.

RESULTS

Among 3615 admitted vaccinees, 822 (23%) were positive for influenza. We observed a lower risk of influenza among late vaccinees during the 2011/2012 and 2014/2015A(H3N2)-dominant seasons: aOR=0.68 (95% CI: 0.47-1.00) and 0.69 (95% CI: 0.50-0.95). We found no differences in the risk of admission with influenza among late versus early vaccinees in the 2012/2013A(H1N1)pdm09-dominant or 2013/2014B/Yamagata lineage-dominant seasons: aOR=1.18 (95% CI: 0.58-2.41) and 0.98 (95% CI: 0.56-1.72). When we restricted our analysis to individuals aged 65years or older, we found a statistically significant lower risk of admission with influenza among late vaccinees during the 2011/2012 and 2014/2015A(H3N2)-dominant seasons: aOR=0.61 (95% CI: 0.41-0.91) and 0.69 (95% CI: 0.49-0.96). We observed 39% (95% CI: 9-59%) and 31% (95% CI: 5-50%) waning of vaccine effectiveness among participants aged 65years or older during the two A(H3N2)-dominant seasons. Similar results were obtained in the sensitivity analyses.

CONCLUSION

Waning of vaccine protection was observed among individuals aged 65years old or over in two A(H3N2)-dominant influenza seasons.

Management and referral of patients with severe and poorly controlled asthma in primary care

BACKGROUND

Over 50% of treated patients with asthma in Europe are not well controlled. Their management in primary health care (PHC) differs from that in specialized care, and there is no real coordination between the two.

OBJECTIVES

To identify barriers and solutions to improving the management of patients with severe and poorly controlled asthma and the communication between specialists and PHC, and to reach a consensus on the criteria for referral patients.

METHODS

An observational study using a modified Delphi technique. About 79 physicians from PHC, pneumology and allergy fields from different Spanish regions were invited to participate via an online questionnaire. Consensus was reached on an item when more than two-thirds of the panel members scored within the 3-point category (1-3 or 7-9) containing the median and the interquartile range of answers had to be ≤4 points.

RESULTS

Response rate: 52%. After the second round, consensus items were 40 (62.5%): of which 37 in agreement and 3 in disagreement. Around 92.68% of respondents agreed that it would be useful to incorporate questionnaires for asthma control into PHC computer-based searches. About 100% of participants agreed that clear consensus criteria between PHC and specialists must be determined to decide when a patient with asthma is referred from PHC to specialist or vice versa. Ten of the proposed criteria reached consensus agreement.

CONCLUSION

The failure to use guidelines and specific questionnaires for asthma control in PHC is one reason why there is underdiagnosis and poor control of asthma. Some strategies to improve the asthma care management emerged from the survey results.

Attitudes towards insulin initiation in type 2 diabetes patients among healthcare providers: A survey research

AIMS

To describe the views of healthcare providers about starting insulin in patients with type 2 diabetes and to determine the specific factors that contribute to delay insulin initiation.

METHODS

Two-phases observational descriptive study. In the quantitative phase we conducted a cross-sectional survey of a sample of 380 healthcare professionals (general practitioners (GPs), endocrinologists, internists and nurses). In the qualitative phase, a discussion group reviewed the results of the survey to propose solutions.

RESULTS

In poorly controlled patients, 46% of GPs vs. 43.2% of internists and 31.3% of endocrinologists waited 3-6months before starting insulin, and 71.4% of GPs vs. 66.7% of internists vs. 58.8% of endocrinologists need to confirm twice the HbA1c levels. The upper level of basal glucose more frequently considered as good control is 130mg/dL for GPs (35.7%), and 120mg/dL for internists (35.8%) and endocrinologists (37.5%). In patients without comorbidities, 32.5% of endocrinologists vs. 27.2% of internists vs. 17.9% of GPs initiated insulin when HbA1c was >7% while 26.3% of endocrinologists vs. 28.4% of internists vs. 38.4% of GPs initiated insulin when HbA1c was >8%. The interference of the therapy with the patient' social life and the need for time management were the most accepted barriers to initiate insulin.

CONCLUSIONS

There are significant differences between GPs and endocrinologists regarding the insulin initiation and GPs and internists felt less empowered to manage patients with diabetes. Specific training for professionals and joint work with patients could improve the glycemic control.

Inclusion of the equity focus and social determinants of health in health care education programmes in Colombia: a qualitative approach

PURPOSE

The Pan American Health Organization (PAHO) and the Colombian Ministry of Health and Social Protection have determined a need for an approach to include Equity Focus (EF) and Social Determinants of Health (SDH) in health training programmes in Colombia. We studied the incorporation of EF and SDH in the curricula of several universities in Colombia to identify opportunities to strengthen their inclusion.

METHODS

Qualitative methodology was performed in two stages: (i) initial exploration (self-administered questionnaires and review of curricula) and (ii) validation of the information (semi-structured interviews).

RESULTS

The inclusion of the EF and SDH in university curricula is regarded as an opportunity to address social problems. This approach addresses a broad cross-section of the curriculum, especially in the subjects of public health and Primary Health Care (PHC), where community outreach generates greater internalization by students. The dominance of the biomedical model of study plans and practice scenarios focusing on disease and little emphasis on community outreach are factors that limit the inclusion of the approach.

CONCLUSIONS

The inclusion of EF and SDH in university curricula in Colombia has primarily focused on increasing the knowledge of various subjects oriented towards understanding the social dynamics or comprehensiveness of health and disease and, in some programmes, through practical courses in community health and PHC. Increased integration of EF and SDH in subjects or modules with clinical orientation is recommended.

Construction and validation of a model to predict nonadherence to guidelines for prescribing antiplatelet therapy to hypertensive patients

OBJECTIVE

To construct and validate a model to predict nonadherence to guidelines for prescribing antiplatelet therapy (NGAT) to hypertensive patients.

METHODS

This 3 month prospective study was undertaken in 2007-2009 to determine whether 712 hypertensive patients were or were not being prescribed antiplatelet therapy.

OUTCOME

NGAT according to clinical guidelines (just for patients in secondary prevention or with Systematic COronary Risk Evaluation (SCORE) ≥10%). Secondary variables: Duration of hypertension (years), blood pressure (BP), age, gender, smoking, diabetes, dyslipidemia, cardiovascular disease, lipid parameters, SCORE. Of the whole sample 80% was used to construct the model and 20% to validate it. To construct the model, we performed a multivariate logistic regression model which was adapted to be a scoring system with risk groups. The adjusted odds ratios (ORs) were obtained through the model. To validate the model we calculated the area under the ROC curve (AUC) and then compared the expected and the observed NGAT. The final model was adapted for use as a mobile application.

RESULTS

NGAT: 18.5%, construction; 17.9%, validation.

FACTORS

higher duration of hypertension diagnosis, higher systolic BP, older age, male gender, smoking, diabetes, dyslipidemia and cardiovascular disease.

VALIDATION

AUC = 0.82 (95% CI: 0.74-0.90, p < 0.001), with no differences between the observed and the expected NGAT (p = 0.334).

CONCLUSION

A tool was constructed and validated to predict NGAT. The associated factors were related with a greater cardiovascular risk. The scoring system has to be validated in other areas.

Differences in the management of hypertension, diabetes mellitus and dyslipidemia between obesity classes

We did not find any paper that assessed clinical inertia in obese patients. Therefore, no paper has compared the clinical inertia rates between morbidly and nonmorbidly obese patients. A cross-sectional observational study was carried out. We analysed 8687 obese patients ⩾40 years of age who attended their health-care center for a checkup as part of a preventive program. The outcome was morbid obesity. Secondary variables were as follows: failure in the management of high blood pressure (HBP), high blood cholesterol (HBC) and high fasting blood glucose (HFBG); gender; personal history of hypertension, dyslipidemia, diabetes, smoking and cardiovascular disease; and age (years). We analysed the association between failures and morbid obesity by calculating the adjusted odds ratio (OR). Of 8687 obese patients, 421 had morbid obesity (4.8%, 95% confidence interval (CI): 4.4-5.3%). The prevalence rates for failures were as follows: HBP, 34.7%; HBC, 35.2%; and HFBG, 12.4%. Associated factors with morbid obesity related with failures were as follows: failure in the management of HBP (OR=1.42, 95% CI: 1.15-1.74, P=0.001); failure in the management of HBC (OR=0.73, 95% CI: 0.58-0.91, P=0.004); and failure in the management of HFBG (OR=2.24, 95% CI: 1.66-3.03, P<0.001). Morbidly obese patients faced worse management for HBP and HFBG, and better management for HBC. It would be interesting to integrate alarm systems to avoid this problem.

Magnitude of pharmacological nonadherence in hypertensive patients taking antihypertensive medication from a community pharmacy in Spain

BACKGROUND

The most common factor associated with poor control of hypertension is treatment nonadherence to antihypertensive drug therapy. 

OBJECTIVE

To measure drug nonadherence and associated factors in pharmacologically treated hypertensive patients.

METHODS

A prospective observational study was carried out from March 2007 to August 2009 at a community pharmacy in Spain. A pharmacist invited a convenience sample of hypertensive patients aged 50 years and older taking antihypertensive medication for at least 3 months prior to participate in the study. Drug nonadherence was analyzed by 3 separate methods: pill count, as the gold standard method, and Haynes-Sackett and Morisky-Green questionnaires. A descriptive analysis of drug nonadherence and variables associated with nonadherence was performed. Logistic regression models were used to determine the variables associated with nonadherence. 

RESULTS

Data were recorded from 419 patients. The drug nonadherence ratio varied depending on the method used: 62.8% by pill count, 3.1% by the Haynes-Sackett self-report test, and 36% according to the Morisky-Green test. In the multivariate model, the variable associated with a decrease in drug nonadherence was years of known hypertension (OR = 0.962, 95% CI = 0.937-0.988), and the variables associated with an increase in drug nonadherence were loose-pill combination therapy versus fixed-dose combination therapy or monotherapy (OR = 4.099, 95% CI = 2.494-6.757) and good perception of quality of life (OR = 1.276, 95% CI = 1.109-1.471).

CONCLUSIONS

The magnitude of drug nonadherence varies depending on the method of measurement. The pill count method (reference method) revealed that 2 out of 3 patients with hypertension did not have good adherence. This study highlights the lack of antihypertensive drug adherence and the pharmacist's ability to detect the associated factors in order to find the best way to deal with nonadherence.

Suitability of antiplatelet therapy in hypertensive patients

Antiplatelet therapy (AT) is indicated in hypertensive patients with increased cardiovascular risk. The literature about the adequate or inadequate prescription of AT is scarce. We conducted a prospective descriptive study to quantify therapeutic inertia and non-guideline-recommended prescription (NGRP) of AT (aspirinor clopidogrel or both), and to assess associated factors, calculating the adjusted odds ratios (ORs) from multivariate models. In 2007-2009, 712 primary health-care hypertensive patients in a Spanish region were enrolled. Inertia was defined as the lack of an AT prescription, despite being indicated by guidelines, whereas NGRP was defined as AT prescription when there was no guideline recommendation. We also recorded cardiovascular variables. Inertia and NGRP were quantified for primary and secondary prevention. Of 108 patients in secondary prevention, 53 had inertia (49.1%, 95% confidence interval (CI): 39.6-58.5%). Associated profile: female (OR=0.460, P=0.091), no dyslipidemia (OR=0.393, P=0.048), no coronary heart disease (OR=0.215, P=0.001) and high diastolic blood pressure (OR=1.076, P=0.016). In primary prevention, NGRP was present in 69 of 595 patients (11.6%, 95% CI: 9.0-14.2%). Associated profile: male (OR=1.610, P=0.089), smoking (OR=2.055, P=0.045), dyslipidemia (OR=3.227, P<0.001) and diabetes (OR=2.795, P<0.001). Although certain factors were clearly associated with these phenomena much still remains to be learnt.

Are obese patients assisted in losing weight?

OBJECTIVES

To quantify obesity inertia (OI) in primary healthcare in the Valencian Community (Spain) and determine the related factors.

STUDY DESIGN

Cross-sectional analysis.

METHODS

In 2003, the whole population 40 years and older was invited to undergo a check-up. We included all obese persons (body mass index [BMI] ≥ 30 kg/m2) of the first 6 months after the invitation (n = 8687). OI was defined as the lack of advice by the healthcare professionals to lose weight. Other data recorded: gender, history of cardiovascular risk factors (CVRFs) or cardiovascular disease (CVD), groups of BMI (Class I obesity [BMI < 35 kg/m2] and the rest), age, blood pressure, and lipids. The patients without CVD and who were younger than 75 years (n = 7700) were classified according to the REGICOR cardiovascular risk as either high or low. The OI was quantified and related factors assessed, calculating the adjusted odds ratios (ORs) from multivariate models.

RESULTS

In the overall sample, OI was 16.6% (95% confidence interval [CI], 15.8-17.4). Associated factors: male (OR = 1.19; 95% CI, 1.06-1.35); no history of hypertension (OR = 0.85; 95% CI, 0.74-0.97), or dyslipidaemia (OR = 0.86; 95% CI, 0.73-1.01), or diabetes (OR = 0.80; 95% CI, 0.64-1.00), or CVD (OR = 0.79; 95% CI, 0.62-1.01); and Class I obesity (OR = 0.83; 95% CI, 0.72-0.96). In the REGICOR sample, the OI was 16.9% (95% CI, 16.0-17.7). Associated factors: high REGICOR (OR = 2.27; 95% CI, 1.30-3.98) and Class I obesity (OR = 0.82; 95% CI, 0.71-0.95).

CONCLUSIONS

OI exists in 1 of every 6 patients. OI occurs less frequently in patients with a history of CVRF, and more frequently in Class I obesity and in those with a high cardiovascular risk.

Non-compliance and inertia in hypertensive Spaniards at high cardiovascular risk: CUMPLE study

OBJECTIVE

To assess non-compliance (NC) and therapeutic inertia (TI) after 6 months of follow-up in hypertensive patients with poorly controlled blood pressure and high cardiovascular risk.

RESEARCH DESIGN AND METHODS

Longitudinal, multicentre study; 3900 uncontrolled hypertensive patients were recruited from 585 primary healthcare centres. Tablets were counted during visits at baseline, 1, 3 and 6 months. A tablet count between 80-100% was considered as compliant. Multivariate logistic regression was performed to determine variables associated with NC and TI.

RESULTS

A total of 3636 patients completed, mean age was 64.8 (SD 10.8) years, 53.7% being male. After one month, 61.8% (60.2-63.4) had uncontrolled blood pressure, 39.5% (37.9-41.1) were NC and 52.3% (50.2-54.4) had TI. At the end of follow-up, uncontrolled blood pressure was 34.6% (33.1-36.1) (p < 0.05), NC was 46.8% (45.2-48.4) (p < 0.05) and TI was 34.2% (31.6-36.8) (p < 0.05). The variable associated with NC was greatest number of antihypertensive treatments (OR 1.09, 95% CI 1.05-1.13, p < 0.001), and variables associated with TI were least number of antihypertensive drugs (OR 0.88, 95% CI 0.84-0.98, p < 0.001) and least number of diseases suffered (OR 0.95, 95% CI 0.92-0.98, p = 0.002).

LIMITATIONS

Due to the complexity of measuring compliance, we have to assume measurement bias.

CONCLUSIONS

Among uncontrolled hypertensive patients, after completing 6 months follow-up, approximately one out of two patients were NC and one out of three physicians committed TI.

Framingham risk score for prediction of cardiovascular diseases: a population-based study from southern Europe

BACKGROUND

The question about what risk function should be used in primary prevention remains unanswered. The Framingham Study proposed a new algorithm based on three key ideas: use of the four risk factors with the most weight (cholesterol, blood pressure, diabetes and smoking), prediction of overall cardiovascular diseases and incorporating the concept of vascular age. The objective of this study was to apply this new function in a cohort of the general non Anglo-Saxon population, with a 10-year follow-up to determine its validity.

METHODS

The cohort was studied in 1992-94 and again in 2004-06. The sample comprised 959 randomly-selected persons, aged 30-74 years, who were representative of the population of Albacete, Spain. At the first examination cycle, needed data for the new function were collected and at the second examination, data on all events were recorded during the follow-up period. Discrimination was studied with ROC curves. Comparisons of prediction models and reality in tertiles (Hosmer-Lemeshow) were performed, and the individual survival functions were calculated.

RESULTS

The mean risks for women and men, respectively, were 11.3% and 19.7% and the areas under the ROC curve were 0.789 (95%CI, 0.716-0.863) and 0.780 (95%CI, 0.713-0.847) (P<0.001, both). Cardiovascular disease events occurred in the top risk tertiles. Of note were the negative predictive values in both sexes, and a good specificity in women (85.6%) and sensitivity in men (79.1%) when their risk for cardiovascular disease was high. This model overestimates the risk in older women and in middle-aged men. The cumulative probability of individual survival by tertiles was significant in both sexes (P<0.001).

CONCLUSIONS

The results support the proposal for "reclassification" of Framingham. This study, with a few exceptions, passed the test of discrimination and calibration in a random sample of the general population from southern Europe.

Effectiveness of a new health care organization model in primary care for chronic cardiovascular disease patients based on a multifactorial intervention: the PROPRESE randomized controlled trial

Background

To evaluate the effectiveness of a new multifactorial intervention to improve health care for chronic ischemic heart disease patients in primary care. The strategy has two components: a) organizational for the patient/professional relationship and b) training for professionals.

Methods/design

Experimental study. Randomized clinical trial. Follow-up period: one year. Study setting: primary care, multicenter (15 health centers). For the intervention group 15 health centers are selected from those participating in ESCARVAL study. Once the center agreed to participate patients are randomly selected from the total amount of patients with ischemic heart disease registered in the electronic health records. For the control group a random sample of patients with ischemic heart disease is selected from all 72 health centers electronic records.

Intervention components: a) Organizational intervention on the patient/professional relationship. Centered on the Chronic Care Model, the Stanford Expert Patient Program and the Kaiser Permanente model: Teamwork, informed and active patient, decision making shared with the patient, recommendations based on clinical guidelines, single electronic medical history per patient that allows the use of indicators for risk monitoring and stratification. b) Formative strategy for professionals: 4 face-to-face training workshops (one every 3 months), monthly update clinical sessions, online tutorial by a cardiologist, availability through the intranet of the action protocol and related documents.

Measurements: Blood pressure, blood glucose, HbA1c, lipid profile and smoking. Frequent health care visits. Number of hospitalizations related to vascular disease. Therapeutic compliance. Drug use.

Discussion

This study aims to evaluate the efficacy of a multifactorial intervention strategy involving patients with ischemic heart disease for the improvement of the degree of control of the cardiovascular risk factors and of the quality of life, number of visits, and number of hospitalizations.

Clinical inertia in poorly controlled elderly hypertensive patients: a cross-sectional study in Spanish physicians to ascertain reasons for not intensifying treatment

BACKGROUND

Clinical inertia, the failure of physicians to initiate or intensify therapy when indicated, is a major problem in the management of hypertension and may be more prevalent in elderly patients. Overcoming clinical inertia requires understanding its causes and evaluating certain factors, particularly those related to physicians.

OBJECTIVE

The objective of our study was to determine the rate of clinical inertia and the physician-reported reasons for it.

METHODS

An observational, cross-sectional, multi-center study was carried out in a primary care setting. We included 512 physicians, with a consecutive sampling of 1,499 hypertensive patients with clinical inertia.

MAIN OUTCOME MEASURE

Clinical inertia was defined when physicians did not modify treatment despite knowing that the therapeutic target had not been reached. Clinical inertia was considered to be justified (JCI) when physicians provided an explanation for not intensifying treatment and as not justified (nJCI) when no reasons were given.

RESULTS

JCI was observed in 30.1 % (95 % CI 27.8-32.4) of patients (n = 451) and nJCI in 69.9 % (95 % CI 67.6-72.2) (n = 1,058). JCI was associated with higher blood pressure (BP) values (both systolic and diastolic) and diabetes (p = 0.012) than nJCI. nJCI was associated with patients having an isolated increase of systolic or diastolic or high borderline BP values or cardiovascular disease.

CONCLUSION

Physicians provided reasons for not intensifying treatment in poorly controlled patients in only 30 % of instances. Main reasons for not intensifying treatment were borderline BP values, co-morbidity, suspected white coat effect, or perceived difficulty achieving target. nJCI was associated with high borderline BP values and cardiovascular disease.

Effectiveness of the 2010-2011 seasonal influenza vaccine in preventing confirmed influenza hospitalizations in adults: a case-case comparison, case-control study

Introduction

We estimated influenza vaccine effectiveness (IVE) to prevent laboratory-confirmed influenza-related hospitalizations in patients 18 years old or older during the 2010–2011 influenza season.

Methods

We conducted a prospective case-control study in five hospitals, in Valencia, Spain. Study subjects were consecutive emergency hospitalizations for predefined conditions associated with an influenza-like illness episode <8 days before admission. Patients were considered immunized if vaccinated ≥14 days before influenza-like illness onset. Cases were those with a real time reverse transcriptase polymerase chain reaction (RT-PCR) positive for influenza and controls were RT-PCR positive for other respiratory viruses. Adjusted IVE was estimated as 100 × (1 − adjusted odds ratio). To account for indication bias we computed adjusted IVE for respiratory syncytial virus related hospitalizations.

Results

Of 826 eligible hospitalized patients, 102 (12%) were influenza positive and considered cases, and 116 (14%) were positive for other respiratory viruses and considered controls. Adjusted IVE was 54% (95% confidence interval, 11–76%). By subgroup, adjusted IVE was 53% (4–77%) for those with high-risk conditions, 59% (16–79%) for those ≥60 years of age, and, 54% (4–79%) for those ≥60 years of age with high-risk conditions. No influenza vaccine effect was observed against respiratory syncytial virus related hospitalization.

Conclusion

Influenza vaccination was associated with a significant reduction on the risk of confirmed influenza hospitalization, irrespective of age and high-risk conditions.

[Inter-professional relationship between primary health care (PHC) and secondary care (hospital) in 1992 and 2000. A Delphi study]

AIM

To evaluate the trends in the inter-professional relationship between primary health care (PHC) and secondary care (hospital) at 2 different moments of the health reform, at its start in 1992 and after a phase of consolidation (2001).

DESIGN

Observational study based on modified Delphi technique.

SETTING

Valencia Community, Spain.

PARTICIPANTS

One hundred and ninety six professionals from Valencia Community were selected (103 PH centre administrators, 43 hospital and PC medical directors, and 50 heads of internal medicine or emergency services).

RESULTS

One hundred and ninety six questionnaires were sent out, with a response rate of 38%. In PHC problems remained the same, but the following got worse: "lack of motivation" (+1.34), "lack of overall vision of patients" (+1.10), and "overuse of medical services" (+1.06). The existence of non-integrated out-patient specialists got better (-1.32). In hospitals, "lack of overall vision of patients" got worse (+0.51), but in general problems got better, especially in "lack of communication and dialogue" (-1.14). PC increased its demand for "a single computerized clinical record" (+1.50), drawing up of common protocols (+0.86), and periodic rotations of PC doctors through hospitals (+0.85), but bureaucratic referrals to PC (-0.60) and the need for specialists in PC as consultants (-0.36) diminished. In hospitals all solutions showed lower scores, particularly access of PC doctors to monitoring of admitted patients (-2.44) and PC doctors doing hospital cover (-2.30).

CONCLUSIONS

Problems and solutions from PHC and hospitals remain the same, but there is a trend to the worse in PHC, whereas in hospitals the trend is more positive.
