Health inequalities in childhood diseases: temporal trends in the inter-crisis period

BACKGROUND

Since 2008, children in Catalonia (Spain) have suffered a period of great economic deprivation. This situation has generated broad-ranging health inequalities in a variety of diseases. It is not known how these inequalities have changed over time. The aim of the present study is to determine trends in inequalities over this period in ten relevant diseases in children according to sex and age.

METHODS

A retrospective cross-sectional population-based study of all children under 15 years old resident in Catalonia during the 2014-2021 period (over 1.2 million children/year) and of their diagnoses registered by the Catalan Health System. Health inequalities were estimated by calculating the relative index of inequality and time trends using logistic regression models. Interaction terms were added to test for the effects of sex on time trends.

RESULTS

Increasing significant temporal trends in inequalities were shown for both sexes in almost all the diseases or adverse events studied (asthma, injuries, poisoning, congenital anomalies, overweight and obesity), in mood disorders in boys, and in adverse birth outcomes in girls. Adjustment and anxiety and mood disorders in girls showed a decreasing temporal trend in inequalities. More than half of the diseases and adverse events studied experienced significant annual increases in inequality. Poisoning stood out with an average annual increase of 8.65% [4.30, 13.00], p ≤ 0.001 in boys and 8.64% [5.76, 11.52], p ≤ 0.001) in girls, followed by obesity with increases of 5.52% [4.15, 6.90], p =  < 0.001 in boys and 4.89% [4.26, 5.51], p ≤ 0.001) in girls.

CONCLUSIONS

Our results suggest that inequalities persist and have increased since 2014. Policy makers should turn their attention to how interventions to reduce Health inequalities are designed, and who benefits from them.

The influence of general practitioner and patient sex on the treatment of major depression

Introduction: Biological and sociocultural factors may lead to a significant gender bias in the treatment of major depression and thus contribute to accentuating gender inequalities. However, the influence of the general practitioner's (GP's) sex on the prescription of antidepressants has not been adequately assessed in previous work and remains unclear. This retrospective cohort study aims to determine the influence of GP and patient sex on the treatment of major depression. Methods: The study population comprised 87,629 patients (33.56% male patients and 66.44% female patients) aged over 15 years newly diagnosed with major depression recorded between 2017 and 2019 in Catalonia, Spain. Logistic regression models were used to evaluate the effect of GP sex on the therapeutic strategy (i.e., whether antidepressants were prescribed at the first diagnostic visit). Cox proportional hazards models and survival analyses were conducted to compare, according to GP and patient sex, the probability that a patient would be prescribed an antidepressant at any time during the study period. Finally, a multiple linear regression analysis was performed to assess the pharmacological intensity of the treatment [monthly fluoxetine-equivalent defined daily dose (DDD)]. Results: Female patients were more likely to be prescribed an antidepressant at the time of diagnosis, both by male [OR = 1.11, 95% CI = (1.05, 1.17), p < 0.001] and female GPs [OR = 1.13, 95% CI = (1.09, 1.17), p < 0.001]. Similarly, female patients were 8% and 9% more likely than male patients to be prescribed an antidepressant from male [HR = 1.08, 95% CI = (1.05, 1.11), p < 0.001] and female GPs [HR = 1.09, 95% CI = (0.92, 1.07), p < 0.001], respectively, during the study period. Female GPs prescribed less antidepressants than male GPs: an average of 0.39 less monthly fluoxetine-equivalent DDD [β = -0.39, 95% CI = (0.10, -3.92), p < 0.001]. Discussion: Few differences are observed between male and female GPs regarding the therapeutic strategy and its intensity for the treatment of major depression. However, both male and female GPs are influenced by biases and stereotypes that entail differential antidepressant-prescribing behaviors in accordance with the sex of the patient and their characteristics.

Socioeconomic inequalities in waiting times for planned and cancer surgery: Evidence from Spain

Waiting times act as a non-price rationing mechanism to bring together the demand for and the supply of public healthcare services and ensure equal access independently of ability to pay. This study tests for the presence of socioeconomic inequalities in waiting times for ten publicly-funded planned and cancer surgeries in Catalonia (Spain) in 2015-2019. Socioeconomic status (SES), measured by four categories (very low, low, middle, high), is based on co-payment levels for medicines which depend on patient's income. Using administrative data, we estimate the association between SES and waiting times controlling for patient characteristics and hospital fixed effects. Compared to patients with low SES, patients with middle SES wait 2-6 fewer days for hip replacement, cataract surgery, and hysterectomy, and less than a day for breast cancer surgery. These inequalities arise within hospitals and are not explained by patient nor hospital characteristics. For some surgeries, the results also show that patients with higher SES are more likely to voluntarily exit the waiting list and have a lower probability of having a surgery canceled for medical reasons and dying while waiting.

Air Pollution and Birth Outcomes: Health Impact and Economic Value Assessment in Spain

Air pollution is considered an ongoing major public health and environmental issue around the globe, affecting the most vulnerable, such as pregnant women and fetuses. The aim of this study is to estimate the health impact and economic value on birth outcomes, such as low birthweight (LBW), preterm birth (PTB), small for gestational age (SGA), attributable to a reduction of PM₁₀ levels in Spain. Reduction based on four scenarios was implemented: fulfillment of WHO guidelines and EU limits, and an attributable reduction of 15% and 50% in annual PM₁₀ levels. Retrospective study on 288,229 live-born singleton children born between 2009-2010, using data from Spain Birth Registry Statistics database, as well as mean PM₁₀ mass concentrations. Our finding showed that a decrease in annual exposure to PM₁₀ appears to be associated with a decrease in the annual cases of LBW, SGA and PTB, as well as a reduction in hospital cost attributed to been born with LBW. Improving pregnancy outcomes by reducing the number of LBW up to 5% per year, will result in an estimate associated monetary saving of 50,000 to 7,000,000 euros annually. This study agrees with previous literature and highlights the need to implement, and ensure compliance with, stricter policies that regulate the maximum exposure to outdoor PM permitted in Spain, contributing to decreased environmental health risk, especially negative birth outcomes.

How should healthcare be reported in Catalonia? Qualitative study with healthcare leaders

BACKGROUND

The Results Centre is the name of a project that, since 2012, has been openly publishing the results of each healthcare centre in Catalonia, with the idea of promoting benchmarking among centres and transparency toward society. As the project evolves, it has become increasingly necessary to adapt its contents and formats. The objective of this study is to identify the preferences and expectations of healthcare leaders regarding the Results Centre.

METHODS

A qualitative study was conducted using the nominal group technique. Five nominal groups were created with the participation of 58 professionals (26 from hospital care, 16 from primary care, and 16 from long-term care centres). The areas of analysis were: (1) what the Results Centre of the future should be like; (2) what information needs should be addressed; and (3) what novelties should be incorporated to stimulate quality improvement. The spontaneity of ideas, intensity of recommendations, and intergroup consistency were analysed. The study was conducted in April 2019.

RESULTS

The requirements reported by the participants to be met by the Results Centre included: being a tool for benchmarking and strategic decision-making; adjusted and segmented indicators; non-clinical information (patient experience, socio-economic status, etc.); and data accessible to all stakeholders, including citizens. The ideas were consistent across the different levels of care, although the intensity of recommendations varied depending on their content.

CONCLUSIONS

Regional agencies that are accountable for health outcomes should be consistently committed to adapting to the needs of different stakeholders in the health system. This project is an example of how this requirement has been addressed in Catalonia.

[Results Centre of Social and Health Care Network in Catalonia. Evolution 2013-2018]

OBJECTIVE

The Results Centre's (RC) mission is to measure, evaluate and disseminate the results achieved by the different agents of the health system, based on relevant measures. The purpose of this research is to describe the evolution of indicators used in the social and health care network RC (RC-SH), including some indicators sensitive to nursing practice.

METHOD

Observational, descriptive cross-sectional study based on data from 6 RC-SH reports (2013-2018). Indicators including activity carried out, days of stay, achievement of rehabilitation goals, discharge to home, mortality and pressure ulcers are analysed.

RESULTS

There was an increase in activity on the different social and health resources and days of stay decrease. Results were heterogeneous between centres. Functional improvement and home discharge showed an increasing trend, while mortality tended to decrease. The prevalence of grade III-IV pressure ulcers was maintained.

CONCLUSIONS

RC-SH reports have included different indicators to improve the capacity of evaluation and benchmarking for social and health network. These reports provide transparency and accountability in the field and invite further improvement in this sector. Also RC-SH results show that social and health network evolves towards intermediate care with the entry of subacute resources and the greater efficiency of convalescence. The incorporation of indicators sensitive to nursing practice contributes to making nurses and nursing care visible.

An estimation of the social cost of illicit drug consumption in Catalonia

Worldwide, as well as in Spain, the use of illegal drugs is among the major contributors to the global burden of disease. Quantifying the costs that illegal drugs impose on society is key in terms of decision-making. The objective of this paper is to estimate the social cost of illicit drug consumption in Catalonia for a specific year, and to establish a methodology to be able to replicate such estimations regularly and monitor properly the impact of national plans. To do that, a cost of illness study was performed. For the estimation of mortality and morbidity costs, we relied on the Attributable Fraction approach. Only public sector costs were included: healthcare and non-healthcare costs. The cost of illegal drug consumption in Catalonia in 2011 was estimated at €326.39 million (0.16% of the Catalan GDP in 2011; 0.15% in 2018). Of the total cost, 82% corresponded to direct costs. Among direct costs, 30.32% corresponded to the penal system, 15.99% to hospitalizations, 13.48% to the police force, 17.19% to pharmacy, 8.34% to treatment in specialized centres, and 5.74% to therapeutic communities, among others. Indirect costs represented 18% of total costs, mostly lost income due to drug-related death. This study has been an opportunity to systematically collect data and think about the potential economic returns that could be achieved from effective policies and programs aimed at reducing the consumption of illegal drugs.

Trends in healthcare resource use and expenditure before and after ischaemic stroke. A population-based study

INTRODUCTION

Despite improved survival rates, stroke represents an increasing healthcare and socioeconomic burden. We describe the main characteristics of patients with ischaemic stroke and resource use and associated expenditure one year before and 3 years after stroke, using a population-based dataset.

METHODS

The information technology systems of the Catalan Health Service were used to identify patients with ischaemic strokes occurring between January 2012 and December 2016. For each patient, information from one year before the stroke and up to 3 years thereafter was linked across databases. We describe annual and monthly resource use and healthcare expenditure per patient.

RESULTS

We identified 36,044 patients with ischaemic stroke (mean age, 74.7±13.3 years). The survival rate at 3 years was 63%. Average expenditure per patient was €3,230 the year before stroke, €11,060 for year one after stroke, €4,104 for year 2, and €3,878 for year 3. The greatest determinants of cost in year one were hospitalisation (including initial hospitalisation), representing 45% of the difference in expenditure compared to the previous year, and convalescence and rehabilitation services, representing 33% of this difference. After year one, the increase in expenditure was mainly determined by additional hospital admissions and drug treatment.

CONCLUSION

After ischaemic stroke, healthcare expenditure increases primarily because of initial hospitalisation. After year one, the expenditure decreases but remains above baseline values. Information from population-based datasets is useful for improving the planning of stroke services.

The impact of an easy access drug supply management policy law on the consumption and abuse of opioids in Catalonia: A population-based study

BACKGROUND

Over the last two decades, the rise in opioid prescription has worsened health outcomes worldwide, increasing both levels of abuse and mortality rates. In order to reduce the scale of this public health problem, new policies have been implemented in many countries. In 2012, Spain adopted new legislation on opioid prescription (the ROE law), which meant that practitioners no longer needed to obtain extra authorisation in order to prescribe strong opioids. The objective of the paper is to assess the impact of this law on opioid use and abuse in Catalonia, Spain.

METHODS

We established two measures of the use of strong and weak opioids: DDDs, and abuse. We used benzodiazepines and antidepressants as controls, and adjusted for age, sex, drug co-payment level, death or near death, cancer diagnosis, morbidity group, and type of prescription. The data were obtained from administrative and dispensing drug databases in a population of 7.5 million inhabitants. We estimated two-way fixed effects using difference in difference models.

RESULTS

The ROE law impacted reducing the monthly use of strong opioids by 0.903 DDDs, representing a 3.15% decrease in the mean monthly use of strong opioids. However, abuse rose 1.86 times compared with the average pre-ROE value, which represents an increase of 11,190 months of opioid abuse (i.e., an 11.33% of all monthly opioids use).

CONCLUSION

The abolition of the duplicate prescription programme for strong opioids led to a reduction in the average monthly use of strong opioids, but an increase in abuse.

Do hospitals have a higher mortality rate on weekend admissions? An observational study to analyse weekend effect on urgent admissions to hospitals in Catalonia

BACKGROUND

'Weekend effect' is a term used to describe the increased mortality associated with weekend emergency admissions to hospital, in contrast with admission on weekdays. The objective of the present study is to determine whether the weekend effect is present in hospitals in Catalonia.

METHODS

We analysed all urgent admissions in Catalonia in 2018, for a group of pathologies. Two groups were defined (those admitted on a weekday and those admitted on a weekend). We obtained mortality at 3, 7, 15 and 30 days, and applied a proportions test to both groups. Additionally, we used Cox's regression for mortality at 30 days, using the admission on a weekend as the exposition, adjusting by socioeconomic and clinical variables. We used the hospital discharge database and the Central Registry of the Insured Population.

RESULTS

72 427 admissions for the selected pathologies during 2018 were found. No statistically significant differences in mortality at 30 days (p=0.524) or at 15 days (p=0.119) according to the day of admission were observed. However, significant differences were found in mortality at 7 days (p=0.025) and at 3 days (p=0.002). The hazard rate associated with the weekend was 1.13 (95% CI: 1.04 to 1.23). By contrast, the adjusted HR of the weekend interaction with time was 0.99 (95% CI: 0.99 to 1.00).

CONCLUSIONS

There is a weekend effect, but it is not constant in time. This could suggest the existence of dysfunctions in the quality of care during the weekend.

Geographical, Socioeconomic, and Gender Inequalities in Opioid Use in Catalonia

Background: In recent years, worldwide opioid use has seen a sharp increase, especially for the treatment of chronic non-cancer pain. Catalonia is no exception to this trend. However, no recent studies have addressed the socioeconomic and gender inequalities in opioid use in the different geographical areas of Catalonia.

Methods: We performed an ecological study to analyse the associations between socioeconomic status, gender and the use of opioids in the 372 Health Areas of Catalonia. Robust Poisson models were performed to analyse the data provided from the Central Register of Insured Persons and dispensing data from the Electronic Prescription Database.

Results: The results show that socioeconomic status has a major impact on opioid use, with the most deprived areas presenting the highest levels of use. There are major inequalities in the DDD/1,000 inhabitants per areas. Moreover, women have much higher utilization rates than men, especially in more deprived areas. The greatest difference is observed in the use of weak opioids in women: the DDD/1,000 inhabitants per day was 2.34 in the area with the lowest use, compared with 22.18 in the area with the highest use.

Conclusions: Our findings suggest that stronger action is needed to promote best practices in prescribing for chronic pain and to reduce socioeconomic and gender variation between geographical areas. This study provides a model for routine monitoring of opioid prescription for targeted interventions aimed at lowering high-dose consumption in specifically identified areas.

Trends in healthcare resource use and expenditure before and after ischaemic stroke. A population-based study

INTRODUCTION

Despite improved survival rates, stroke represents an increasing healthcare and socioeconomic burden. We describe the main characteristics of patients with ischaemic stroke and resource use and associated expenditure one year before and 3 years after stroke, using a population-based dataset.

METHODS

The information technology systems of the Catalan Health Service were used to identify patients with ischaemic strokes occurring between January 2012 and December 2016. For each patient, information from one year before the stroke and up to 3 years thereafter was linked across databases. We describe annual and monthly resource use and healthcare expenditure per patient.

RESULTS

We identified 36 044 patients with ischaemic stroke (mean age, 74.7 ± 13.3 years). The survival rate at 3 years was 63%. Average expenditure per patient was €3230 the year before stroke, €11 060 for year 1 after stroke, €4104 for year 2, and €3878 for year 3. The greatest determinants of cost in year 1 were hospitalisation (including initial hospitalisation), representing 45% of the difference in expenditure compared to the previous year, and convalescence and rehabilitation services, representing 33% of this difference. After year one, the increase in expenditure was mainly determined by additional hospital admissions and drug treatment.

CONCLUSION

After ischaemic stroke, healthcare expenditure increases primarily because of initial hospitalisation. After year one, the expenditure decreases but remains above baseline values. Information from population-based datasets is useful for improving the planning of stroke services.

Determinants of the number of days people in the general population spent at home during end-of-life: Results from a population-based cohort analysis

Background

The number of days spent at home in the last six months of life has been proposed as a comprehensive indicator of high-value patient-centered care; however, information regarding the determinants of this outcome is scarce, particularly among the general population. We investigated the determinants of spending time at home within the six months preceding death.

Methods

Population-based, retrospective analysis of administrative databases of the Catalan government. The analysis included adult (≥18 years) individuals who died in Catalonia (North-east Spain) in 2017 and met the McNamara criteria for palliative care. The primary outcome was the number of days spent at home within the last 180 days of life. Other variables included the cause of death, demographic characteristics, and socioeconomic status, stratified as very low, low, mid, and high level.

Results

The analysis included 40,137 individuals (19,510 women; 20,627 men), who spent a median of 140 days (IQR 16–171) at home within the six months preceding death (women 140 [16–171]; men 150 [100–171]). Female gender was an independent factor of staying fewer days at home (OR 0.80 [95% CI 0.77–0.82]; p<0.001). Higher socioeconomic levels were significantly associated with an increasing number of days at home in both genders: among women, ORs of the low, middle, and high levels were 1.09 (0.97–1.22), 1.54 (1.36–1.75), and 2.52 (1.69–3.75) (p<0.001), respectively; the corresponding ORs among men were 1.27 (1.12–1.43), 1.56 (1.38–1.77), 2.82 (2.04–3.88) (p<0.001). The presence of dementia was a strong predictor of spending less time at home in women (0.41 (0.38–0.43); p<0.001) and men (0.45 (0.41–0.48); p<0.001).

Conclusions

Our results suggest that end-of-life care is associated with gender and socioeconomic inequalities; women and individuals with lower socioeconomic status spend less time at home within the last 180 days of life.

Socioeconomic inequalities in 29 childhood diseases: evidence from a 1,500,000 children population retrospective study

Background

Socioeconomic position (SEP) powerfully affects health status in the childhood population. However, the knowledge of which diseases are more affected by SEP and whose outcomes could be improved by having a more equitable society remains uncertain on a population basis.

Methods

We measured socioeconomic and gender inequalities in the pre-COVID-19 era for 29 diseases in the entire childhood population in Catalonia to identify which diseases are most impacted by inequalities. This population-based study included 1,449,816 children under 15 years old from 2014 to 2017 (48.52% girls) and each of their registered diagnoses within the Catalonia National Health System. We calculated frequency measures by SEP and their sex ratios for each disease. We estimated four regression-based inequality measures: slope index of inequality, relative index of inequality (RII), absolute population-attributable fraction, and population-attributable fraction.

Results

Twenty-five of the 29 diseases examined showed SEP inequalities. The diseases with the greatest inequalities in both sexes were tuberculosis, obesity, adjustment and anxiety disorders, essential hypertension, poisoning, short gestation, low birth weight, foetal growth retardation and intrauterine hypoxia and birth asphyxia and trauma (RII ≥ 2.0); only food allergy showed the opposite pattern (RII < 1.0). Overall, 80,188 (7.80%) of the disease events in boys and 74,921 (8.88%) in girls would be avoided if all children had the same disease rate as those in the medium-high SEP group, with tuberculosis, intrauterine hypoxia and birth asphyxia and trauma, obesity, and short gestation, low birth weight, foetal growth retardation being those that could be reduced the most in relative terms, and dermatitis, injuries, acute bronquitis, and being overweight those that could be reduced the most in absolute terms. Girls present higher RII than boys for respiratory allergy, asthma, dermatitis, being overweight, and obesity (p < 0.05). In contrast, boys showed higher RII compared to girls only in congenital anomalies (p < 0.05).

Conclusions

Socioeconomic and gender inequalities are widely present in childhood health. This indicates that SEP plays a common role in their development although it varies in magnitude according to each disease. It is also a phenomenon that comprises all SEP groups in society. Action needs to be taken to ensure a fairer start in life in terms of health.

Frequency of health-care service use and severity of illness in undocumented migrants in Catalonia, Spain: a population-based, cross-sectional study

BACKGROUND

In Spain, legislation was passed in 2012 excluding undocumented migrants from the public health-care system. Catalonia was one of the Spanish regions that did not implement this legislation, and continued to guarantee access to health care to the whole population. We aimed to analyse health-care use and health status among undocumented migrants in Catalonia, and compare health-care use and health status with legal residents classified according to their socioeconomic position (SEP).

METHODS

We did a population-based, cross-sectional study, with administrative individual data. The study included the resident population in Catalonia, Spain, in 2017, aged younger than 65 years and with a maximum annual income of less than €18 000 per year, and classified into three socioeconomic (SEP) groups-low SEP, very low SEP, and undocumented migrants. Indicators regarding health-care service use (primary care, emergency care, mental health care, acute care), drug prescriptions, and selected chronic and infectious diseases were analysed.

FINDINGS

Between Jan 1 and Dec 31, 2017, 4 071 988 residents of Catalonia were included in this study; undocumented migrants represented 2·8% (n=113 450) of this population. Of all undocumented migrants, 25 942 (61·0%) female participants aged 15-64 years and 19 819 (46·0%) male participants aged 15-64 years attended primary health-care centres: these rates were lower than in individuals with a very low SEP (84·8% in female participants and 72·1% in male participants). Hospital admission rates among male participants aged 15-64 years in the very low SEP group were more than three times as high as in undocumented migrants (111·6 vs 35·7). The highest tuberculosis rate was found in undocumented male migrants (incidence rate 4·35 [95% CI 3·55-5·16]).

INTERPRETATION

Undocumented migrants made less use of health-care services than those in the low and very low SEP groups, but for some infectious diseases, incidence was higher in undocumented migrants. These results constitute an additional argument to support the maintenance of universal health coverage for all citizens.

The experience of Catalonia measuring nurse-sensitive indicators: Trends study 2012-2018

AIM

To describe nursing-sensitive indicators measured in Catalonia.

BACKGROUND

In Catalonia, since 2012, under the umbrella of the Results Centre, outcomes of every health care setting have been published and made open to health care professionals and citizens.

METHODS

Trends study of nursing-sensitive indicators was based on data collected systematically from each setting from 2012 to 2018. Percentages and rates were calculated for each of 14 indicators analysed from all primary care, hospitals and long-term care centres.

RESULTS

Percentage of population aged 60 years or older correctly vaccinated against flu has been decreasing, while percentage of population aged 14 years or under with correct vaccine status is high (over 91%) and has remained stable over time. Mortality in patients who have developed complications has increased, from 27.1% in 2012 to 34.0% in 2017. Most centres achieved functional improvements during the first 30 days of admission.

CONCLUSIONS

Among all indicators measured in primary care, hospital and long-term care, only 14 analysed are nursing-sensitive; no nursing-sensitive indicators regarding mental health are measured.

IMPLICATIONS FOR NURSING MANAGEMENT

Research focused on development of nursing-sensitive indicators offers an opportunity to measure and benchmark nurses' quality of care and their contribution in achieving populations' health improvement and health care system sustainability.

Advance directives and real-world end-of-life clinical practice: a case-control study

BACKGROUND

Advance directives (ADs) have been legally regulated to promote autonomy over health decisions among patients who later lose decision-making capacity.

AIMS AND OBJECTIVES

To analyse the differences in clinical practice at end of life among people who had completed an AD versus those who had not.

METHODS

Retrospective case-control study (1:2), matched by age, sex, year, cause of death and region of residence. The data sources used were the ADs registry, central registry of insured persons, hospital discharge, pharmacy and billing databases, and the mortality registry. Conditional logistic regression models (crude and adjusted by socioeconomic level) were performed. The outcome variable was the frequency of medical procedures performed during the last year of life.

RESULTS

1723 people with ADs who died in Catalonia during 2014-2015 were matched with 3446 dead controls (without ADs). Thoracentesis was the procedure with the greatest reduction among women with an AD (adjusted OR (ORadj) 0.54, 95% CI: 0.32 to 0.89) in conjunction with artificial nutrition (ORadj 0.54, 95% CI: 0.31 to 0.95). Intubation was the procedure with the greatest reduction (ORadj 0.56, 95% CI: 0.33 to 0.94) among men. Slight differences could be seen in the case of cancer deaths. There were no relevant differences when adjusting by socioeconomic level.

CONCLUSIONS

ADs are an effective tool to adjust the realisation of some procedures at end of life. These results can help better plan for the treatment of patients with ADs, as well as increase the awareness among clinical personnel, families and the general population.

Relationship between parents' mental disorders and socioeconomic status and offspring's psychopathology: A cross-sectional study

Mental disorders (MD) are one of the main causes of the disease burden worldwide. Associations between socioeconomic status (SES) and presence of MD in parents have been related with increased odds of MD in offspring. However, there is a lack of population-based research in this field. The aim of the present study was to examine together the relationship between the presence of MD in children, and the SES and presence of MD in their parents, in a whole of population data. A gender approach was undertaken aiming to discern how these variables influence children's mental health when related with the father and the mother. Using administrative individual data from the National Health System, a retrospective cross-sectional study was conducted. The entire children population aged 6 to 15 resident in Catalonia in 2017 was examined. A logistic regression model was performed. Low SES was associated with increased odds of children's MD. Offspring of a parent with MD were at more risk of presenting MD than offspring of parents without these problems. Although these associations were consistent for both boys and girls when looking at the father's or mother's SES and MDs, the mother's SES and MDs showed a higher association with the offspring's MDs than the father's. Lowest associations, found for boys when looking at the father's SES and MDs, were: OR of 1.21, 95%CI 1.16 to 1.27 for lowest SES, and OR of 1.66, 95%CI 1.61 to 1.70 for parental MDs. Children's familiar environment, which includes SES and mental health of parents, plays an important role in their mental health. Socially constructed gender roles interfere with SES and parent's MD. These findings support the relevance of examining MD and its risk factors within a gender approach.

Teleconsultation Between Patients and Health Care Professionals in the Catalan Primary Care Service: Message Annotation Analysis in a Retrospective Cross-Sectional Study

BACKGROUND

Over the last decade, telemedicine services have been introduced in the public health care systems of several industrialized countries. In Catalonia, the use of eConsulta, an asynchronous teleconsultation service between primary care professionals and citizens in the public health care system, has already reached 1 million cases. Before the COVID-19 pandemic, the use of eConsulta was growing at a monthly rate of 7%, and the growth has been exponential from March 15, 2020 to the present day. Despite its widespread usage, there is little qualitative evidence describing how this tool is used.

OBJECTIVE

The aim of this study was to annotate a random sample of teleconsultations from eConsulta, and to evaluate the level of agreement between health care professionals with respect to the annotation.

METHODS

Twenty general practitioners retrospectively annotated a random sample of 5382 cases managed by eConsulta according to three aspects: the type of interaction according to 6 author-proposed categories, whether the practitioners believed a face-to-face visit was avoided, and whether they believed the patient would have requested a face-to-face visit had eConsulta not been available. A total of 1217 cases were classified three times by three different professionals to assess the degree of consensus among them.

RESULTS

The general practitioners considered that 79.60% (4284/5382) of the teleconsultations resulted in avoiding a face-to-face visit, and considered that 64.96% (3496/5382) of the time, the patient would have made a face-to-face visit in the absence of a service like eConsulta. The most frequent uses were for management of test results (26.77%, 1433/5354), management of repeat prescriptions (24.30%, 1301/5354), and medical enquiries (14.23%, 762/5354). The degree of agreement among professionals as to the annotations was mixed, with the highest consensus demonstrated for the question "Has the online consultation avoided a face-to-face visit?" (3/3 professionals agreed 67.95% of the time, 827/1217), and the lowest consensus for the type of use of the teleconsultation (3/3 professionals agreed 57.60% of the time, 701/1217).

CONCLUSIONS

This study shows the ability of eConsulta to reduce the number of face-to-face visits for 55% (79% × 65%) to 79% of cases. In comparison to previous research, these results are slightly more pessimistic, although the rates are still high and in line with administrative data proxies, showing that 84% of patients using teleconsultations do not make an in-person appointment in the following 3 months. With respect to the type of consultation performed, our results are similar to the existing literature, thus providing robust support for eConsulta's usage. The mixed degree of consensus among professionals implies that results derived from artificial intelligence tools such as message classification algorithms should be interpreted in light of these shortcomings.

Comorbidity patterns and socioeconomic inequalities in children under 15 with medical complexity: a population-based study

Background

Children with medical complexity (CMC) denotes the profile of a child with diverse acute and chronic conditions, making intensive use of the healthcare services and with special health and social needs. Previous studies show that CMC are also affected by the socioeconomic position (SEP) of their family. The aim of this study is to describe the pathologic patterns of CMC and their socioeconomic inequalities in order to better manage their needs, plan healthcare services accordingly, and improve the care models in place.

Methods

Cross-sectional study with latent class analysis (LCA) of the CMC population under the age of 15 in Catalonia in 2016, using administrative data. LCA was used to define multimorbidity classes based on the presence/absence of 57 conditions. All individuals were assigned to a best-fit class. Each comorbidity class was described and its association with SEP tested. The Adjusted Morbidity Groups classification system (Catalan acronym GMA) was used to identify the CMC. The main outcome measures were SEP, GMA score, sex, and age distribution, in both populations (CMC and non-CMC) and in each of the classes identified.

Results

71% of the CMC population had at least one parent with no employment or an annual income of less than €18,000. Four comorbidity classes were identified in the CMC: oncology (36.0%), neurodevelopment (13.7%), congenital and perinatal (19.8%), and respiratory (30.5%). SEP associations were: oncology OR 1.9 in boys and 2.0 in girls; neurodevelopment OR 2.3 in boys and 1.8 in girls; congenital and perinatal OR 1.7 in boys and 2.1 in girls; and respiratory OR 2.0 in boys and 2.0 in girls.

Conclusions

Our findings show the existence of four different patterns of comorbidities in CMC and a significantly high proportion of lower SEP children in all classes. These results could benefit CMC management by creating more efficient multidisciplinary medical teams according to each comorbidity class and a holistic perspective taking into account its socioeconomic vulnerability.

Caesarean section trends in Catalonia between 2013 and 2017 based on the Robson classification system: A cross-sectional study

INTRODUCTION

In Catalonia caesarean rates have always been analysed as a single percentage. The objective is to estimate caesarean section rates using the Robson classification in publicly funded hospitals in Catalonia between 2013 and 2017, considering sociodemographic, institutional and obstetric characteristics.

MATERIALS AND METHODS

Cross-sectional population-based study in Catalonia including all women delivering within publicly funded hospitals between 2013-2017 (n = 210 020). The modified Robson classification distribution was estimated, the caesarean rate and the overall contribution, analysed for each year, and by confounders, through logistic regression models.

RESULTS

CS rates decreased steadily between 2013 and 2017 in Catalonia within publicly funded hospitals from 24.3% to 22.8% (cOR 0.92, 95% CI; 0.89 to 0.95). Once adjusted for changes in sociodemographic, institutional and obstetric characteristics the observed decline was even more pronounced (aOR 0.87, 95% CI; 0.84 to 0.90). Within the different groups of Robson once adjusted for confounders, groups 1+2 (aOR 0.88, 95% CI; 0.83 to 0.93), 3+4 (aOR 0.83, 95% CI; 0.78 to 0.89) and 10 (aOR 0.78, 95% CI; 0.68 to 0.90) presented a reduction in caesarean section rates, whereas group 5 showed no significant decrease (aOR 0.95, 95% CI; 0.87 to 1.03%).

CONCLUSIONS

The decrease in caesarean section rates in Catalonia is more pronounced when adjusted for known confounders, suggesting retrospective overutilization of caesarean section and percentages of (in)adequacy in the past. In any case, it remains above the recommended by experts. Further efforts should be made to achieve optimum rates, including improvement on obstetric data collection.

A Cost-Minimization Analysis of a Medical Record-based, Store and Forward and Provider-to-provider Telemedicine Compared to Usual Care in Catalonia: More Agile and Efficient, Especially for Users

Background: Telemedicine (interconsultation between primary and hospital care teams) has been operating in the counties of Central Catalonia Bages, Moianès and Berguedà since 2011, specializing in teledermatology, teleulcers, teleophthalmology and teleaudiometries. For the period until the end of 2019, a total of 52,198 visits were recorded. Objective: To analyze the differential costs between telemedicine and usual care in a semi-urban environment. Methodology: A cost-minimization evaluation, including direct and indirect costs from a societal perspective, distinguishing healthcare and user’s costs, was carried out over a three-month period. Results: Telemedicine saved € 780,397 over the period analyzed. A differential cost favorable to telemedicine of about € 15 per visit was observed, with the patient being the largest beneficiary of this saving (by 85%) in terms of shorter waiting times and travel costs. From the healthcare system perspective, moving the time spent in a hospital care consultation to primary care is efficient in terms of the total time devoted per patient. In social terms and in this context, telemedicine is more efficient than usual care. Conclusion: Allowing users to save time in terms of consultation and travel is the main driver of interconsultation between primary and hospital care savings in a semi-urban context. The telemedicine service is also economically favorable for the healthcare system, enabling it to provide a more agile service, which also benefits healthcare professionals.

General Practitioners' Perceptions of Whether Teleconsultations Reduce the Number of Face-to-face Visits in the Catalan Public Primary Care System: Retrospective Cross-Sectional Study

BACKGROUND

eConsulta is a teleconsultation service involving general practitioners (GPs) and patients. It is part of the information system belonging to Catalonia's primary care service. It has been in operation since the end of 2015 in conjunction with face-to-face consultations with Primary Care Teams as one of the services offered in the patient's Personal Health Folder.

OBJECTIVE

This study aimed to assess the ability of using eConsulta to reduce the number of face-to-face visits to Primary Care Teams.

METHODS

Using 13 categories proposed by the researchers, 18 GPs from the Central Catalonia Health Region retrospectively classified 2268 cases managed with eConsulta and indicated whether, in their opinion, the teleconsultations reduced the number of face-to-face visits.

RESULTS

There was broad consensus among the GPs that eConsulta has the potential to resolve patient queries for every type of consultation. eConsulta avoided the need for a face-to-face visit in 87.9% of cases. In addition, the GPs reported that the ease of access increased the demand for health care support in 27.7% of cases; otherwise, the patient would not have initiated the queries. Therefore, based on the equation (88% x [1-28%]), eConsulta could replace 63%-88% of conventional appointments. The most frequent uses of the teleconsultation service were for management of test results (35.2%), medical enquiries (16.0%), and the management of repeat prescriptions (12.2%). On average, the teleconsultations consisted of a mean 1.57 messages (SD 0.54 messages); 45.9% (1040/2268) of the teleconsultations consisted of 1 message, and the majority of the remaining teleconsultations consisted of 2-5 interactions. The patient initiated 60.0% (1361/2268) of the teleconsultations.

CONCLUSIONS

Based on the GPs' perceptions, eConsulta could replace 63%-88% of conventional appointments. Therefore, asynchronous teleconsultations between practitioners and patients in primary care could avoid interactions that have limited added clinical value.

Teleconsultations between Patients and Healthcare Professionals in Primary Care in Catalonia: The Evaluation of Text Classification Algorithms Using Supervised Machine Learning

Background: The primary care service in Catalonia has operated an asynchronous teleconsulting service between GPs and patients since 2015 (eConsulta), which has generated some 500,000 messages. New developments in big data analysis tools, particularly those involving natural language, can be used to accurately and systematically evaluate the impact of the service. Objective: The study was intended to assess the predictive potential of eConsulta messages through different combinations of vector representation of text and machine learning algorithms and to evaluate their performance. Methodology: Twenty machine learning algorithms (based on five types of algorithms and four text representation techniques) were trained using a sample of 3559 messages (169,102 words) corresponding to 2268 teleconsultations (1.57 messages per teleconsultation) in order to predict the three variables of interest (avoiding the need for a face-to-face visit, increased demand and type of use of the teleconsultation). The performance of the various combinations was measured in terms of precision, sensitivity, F-value and the ROC curve. Results: The best-trained algorithms are generally effective, proving themselves to be more robust when approximating the two binary variables "avoiding the need of a face-to-face visit" and "increased demand" (precision = 0.98 and 0.97, respectively) rather than the variable "type of query" (precision = 0.48). Conclusion: To the best of our knowledge, this study is the first to investigate a machine learning strategy for text classification using primary care teleconsultation datasets. The study illustrates the possible capacities of text analysis using artificial intelligence. The development of a robust text classification tool could be feasible by validating it with more data, making it potentially more useful for decision support for health professionals.

[A deprivation index to reform the financing model of primary care in Catalonia (Spain)]

OBJECTIVE

To build a deprivation index for the assignation of the budgets of the primary healthcare teams in Catalonia (Spain) valid for both urban and rural environments and updatable with greater frequency than indices built from census variables.

METHOD

Starting from a review of the most common deprivation indices, variables were selected from sources that allow frequent updating and are representative at the territorial level of primary care. The correlations were calculated between the chosen variables and variables of need for healthcare and morbidity. principal components analysis was applied. Finally, the correlations of the index built with the MEDEA index and with variables of use of healthcare resources and morbidity was calculated stratifying by geographical dispersion.

RESULTS

The variables of income, occupation and education are the ones with the highest correlation with the need for healthcare and morbidity. The composed socioeconomic index (CSI) ranges from -.01 to 5.68, with an average value of 2.60 and a standard deviation of .91. The correlation between the CSI and the MEDEA index is .89. The CSI correlates with use for healthcare in both urban and rural environments, although in rural environments the association is lower.

CONCLUSIONS

The CSI was built with data that allow frequent updating and was integrated in the model for allocating resources to primary healthcare starting in 2017.

Socioeconomic inequalities in health and the use of healthcare services in Catalonia: analysis of the individual data of 7.5 million residents

Background

The aim of this study is to analyse the health status, the use of public healthcare services and the consumption of prescription drugs in the population of Catalonia, taking into consideration the socioeconomic level of individuals and paying special attention to vulnerable groups.

Methods

Cross-sectional study of the entire population resident in Catalonia in 2015 (7.5 million people) using administrative records. Twenty indicators are analysed related to health, the use of healthcare services and consumption of prescription drugs. Rates, frequencies and averages are obtained for the different variables stratified by age groups (under 15 years, 15–64 years and 65 years or older), gender and socioeconomic status (calculated on the basis of pharmacy copayment levels and Social Security benefits received).

Results

A socioeconomic gradient was observed in all the indicators analysed, in both sexes and in all age groups. Morbidity, use of mental healthcare centres, hospitalisation rates and probability of drug consumption among children is 3–7 times higher for those with low socioeconomic level respect to those with a higher one. In children and adults, the steepest gradient was found in the use of mental health services. Moreover, there are gender inequalities.

Conclusion

There are significant socioeconomic inequalities in health status and in the use of healthcare services in the population of Catalonia. To respond to this situation, new policies on health and other areas, such as education and employment, are required, especially those that have an impact on early years.

[Prioritising measures for consolidating shared decision-making in the services rendered by the Spanish National Health System]

OBJECTIVE

Identify and prioritize according to their relevance, measures, interventions and indispensable instruments to support the establishment of a strategic framework in the Spanish National Health System to enable the responsible and informed exercise of the autonomy of its users and patients for shared decision-making.

METHOD

Group consultation, structured according to procedures adapted from brainstorming techniques, nominal group and Rand consensus method.

RESULTS

The 10 panellists proposed 53 possible actions focusing on "macro" structural measures (legal support and explicit prioritization of shared decision-making on health policy, curricular measures of the teaching system and dynamisation of cultural change), "meso" (generation and dissemination of accredited information by specific research lines and instruments to help shared decision-making), and "micro" activities (measures to stimulate the introduction of shared decision-making in the agency relationship with citizen and users of the healthcare system).

CONCLUSIONS

The consensus emerging from the consultation points to the need to incorporate into the strategic priorities of health policy, structural measures that support and encourage the development of shared decision-making in a number of specific areas of evolution and change in the relationship between health professionals and patients as an attribute of quality in access to the benefits and services of the public healthcare system.

[What kind of health information does the public need? Results of a qualitative study]

INTRODUCTION

In 2016, the users of a Results Centre were asked directly about their health information needs. Three objectives were set: to define the groups interested in receiving the information generated, to determine the contents of the information to be included in the different products, and to identify the formats and channels most suitable for each of the stakeholders.

MATERIAL AND METHODS

Semi-structured personal interviews and focus groups were organised to find out the interests of the users. Personal interviews and on-line consensus dynamics were also performed to determine the interests of the different health professionals, and those of professionals in communication. An analysis of content and discourse was done through the literal transcription of the focus groups and interviews held, as well as the open responses of the consensus dynamics.

RESULTS

Two major interest groups were defined: that of professionals and of the users, with the former sub-divided into different groups according to their professional profile. The main contents of health information to include in the products generated differed for each interest group, as well as the most suitable formats and channels in each case.

DISCUSSION

The information needs of professionals were oriented to the improvement of their professional practice. The importance of working on the dissemination of the information already generated, was also shown. The users stated that they only need information directly related to their health status, and identified their referring doctor as the person in charge of having this information and transmitting it.

Characterization of the CPAP-treated patient population in Catalonia

There are different phenotypes of obstructive sleep apnoea (OSA), many of which have not been characterised. Identification of these different phenotypes is important in defining prognosis and guiding the therapeutic strategy. The aim of this study was to characterise the entire population of continuous positive airway pressure (CPAP)-treated patients in Catalonia and identify specific patient profiles using cluster analysis.

A total of 72,217 CPAP-treated patients who contacted the Catalan Health System (CatSalut) during the years 2012 and 2013 were included. Six clusters were identified, classified as “Neoplastic patients” (Cluster 1, 10.4%), “Metabolic syndrome patients” (Cluster 2, 27.7%), “Asthmatic patients” (Cluster 3, 5.8%), “Musculoskeletal and joint disorder patients” (Cluster 4, 10.3%), “Patients with few comorbidities” (Cluster 5, 35.6%) and “Oldest and cardiac disease patients” (Cluster 6, 10.2%). Healthcare facility use and mortality were highest in patients from Cluster 1 and 6. Conversely, patients in Clusters 2 and 4 had low morbidity, mortality and healthcare resource use.

Our findings highlight the heterogeneity of CPAP-treated patients, and suggest that OSA is associated with a different prognosis in the clusters identified. These results suggest the need for a comprehensive and individualised approach to CPAP treatment of OSA.

Applying artificial neural networks to the diagnosis of organic dyspepsia

Background. Dyspepsia diagnoses and treatment decisions are made in situations in which multiple factors must be taken into account. Evolving from neuro-biological insights, artificial neural networks (ANNs) can employ multiple factors in resolving medical prediction, classification, pattern recognition, and pattern completion. The objective of this study was to compare predictive results classifying people with organic dyspepsia with Helicobacter pylori testing (rapid urease test), a scoring system based on patients' symptoms (derived using logistic regression), classification and regression trees (CART) and the most common ANN approach used in medicine: a feed-forward multilayer perceptron (MLP) trained by back-propagation. Methods. A scoring system, CART algorithm, and MLP model were constructed. Predictive accuracy was calculated for them and for Helicobacter pylori testing.

Results. MLP model had a sensitivity of 0.91 (0.81 for all data) and a specificity of 0.74 (0.79 for all data) for test data. That compares favorably with Helicobacter pylori testing (sensitivity = 0.80, specificity = 0.43), the scoring system (sensitivity = 0.85, specificity = 0.60), and the CART model (sensitivity = 0.88, specificity = 0.53). Diagnostic accuracy, the area under the curve, was 0.82 using the MLP model, 0.61 using Helicobacter pylori testing, 0.78 using the scoring system, and 0.72 for the test set using CART. Conclusions. The results of the analysis showed that the ANN model derived has better predictive accuracy than Helicobacter pylori testing, than a scoring system based on patients' symptoms and than a decision tree algorithm (CART). ANN model could be used as a predictive tool for organic dyspepsia and would be useful in the process of referral of dyspeptic patients from primary care to endoscopy units.

[Vertical social mobility in Spain and ways to improve it. SESPAS report 2014]

In this article, we analyze the extent to which an individual's socioeconomic status is inherited and how equality of opportunity could be increased to improve social mobility. Poverty and deprivation can stop being dynastic-like if the social elevator works. In Spain, income inequality, measured by the Gini coefficient, rose from 0.31 in 2006 to 0.35 in 2012 (moving away from Scandinavia and Central Europe and more closely resembling income inequality in the UK or the United States), while the degree of intergenerational mobility is half-way between that in Italy and the United States. To change this situation and make the social elevator work, primary education should be improved and the health system should be steered toward primary healthcare. This will not be feasible without an improvement in politics and the institutional framework that determine these factors.

[The introduction of technologies in health care systems: from saying to doing]

INTRODUCTION

Health technology assessment (HTA) is a tool based on scientific evidence useful for making decisions about the introduction of technological advances in healthcare systems. However, there are multiple elements that influence the actual use of the results of HTA. These elements are related both to the characteristics of HTA and to the stakeholders involved -health professionals, politicians, and society. The aim of this article was to describe the main elements that influence the applicability of HTA in practice, as well as the use of HTA in clinical practice and health policy.

METHODS

A literature search was performed in PubMed. The references retrieved, as well as additional bibliography and gray literature dealing with different aspects of HTA practice identified from the references retrieved, were reviewed. The results are presented descriptively, with analysis of the studies grouped according to the various HTA-related topics.

RESULTS

Key elements that could be improved are standardization of the evaluation process, description of the organization's mission, prioritization of the technologies to be assessed, the clarity of the presentation of results, inclusion of values other than scientific evidence, such as social and cost-effectiveness values, and increased international coordination.

CONCLUSIONS

For many people, the rationale for HTA is its explicit role in decision making, despite its problems. The immediate future of HTA would seem to include making the assessment process explicit, and the inclusion of HTA in decision making. This entails prioritization of technologies, setting limits on resource allocation and interrelation with political processes.

Economic Impact of Smoke-Free Legislation: Did the Spanish Tobacco Control Law Affect the Economic Activity of Bars and Restaurants?

INTRODUCTION

The potential of smoke-free bans to negatively impact the hospitality business has been an argument of the hospitality and tobacco industry against such legislation. A partial smoke-free legislation was introduced in Spain in 2006 allowing smoking in most bars and restaurants due to the pressure of the hospitality sector. However, this partial ban was later amended in 2011 to include all the hospitality premises without exceptions. The stepped Spanish process permits to evaluate whether the entry into force of the smoke-free legislation had any effect on the economic activity of the hospitality sector.

METHODS

We employed a pooled time series cross-sectional design, with national data over 6 years (2006-2011). The dependent variable used was the total number of bars and restaurants per 100,000 inhabitants. The explanatory variables used were the average amount of spending per household in bars and restaurants, and the total unemployment rate in Spain by regions.

RESULTS

For every 1% increase in the unemployment rate there was a 0.05% decrease in the number of bars and restaurants. In 2007, the number of bars and restaurants was significantly reduced by 13.06% (all others factors being held constant), 4.87% in 2008, and 10.42% in 2009. No statistically significant effect of the smoke-free legislation emerged from 2010 (6.76%) to 2011 (7.69%).

CONCLUSION

The new Spanish smoke-free legislation had no effect on the number of bars and restaurants.

Cost savings associated with 10 years of road safety policies in Catalonia, Spain

OBJECTIVE

To determine whether the road safety policies introduced between 2000 and 2010 in Catalonia, Spain, which aimed primarily to reduce deaths from road traffic collisions by 50% by 2010, were associated with economic benefits to society.

METHODS

A cost analysis was performed from a societal perspective with a 10-year time horizon. It considered the costs of: hospital admissions; ambulance transport; autopsies; specialized health care; police, firefighter and roadside assistance; adapting to disability; and productivity lost due to institutionalization, death or sick leave of the injured or their caregivers; as well as material and administrative costs. Data were obtained from a Catalan hospital registry, the Catalan Traffic Service information system, insurance companies and other sources. All costs were calculated in euros (€) at 2011 values.

FINDINGS

A substantial reduction in deaths from road traffic collisions was observed between 2000 and 2010. Between 2001 and 2010, with the implementation of new road safety policies, there were 26 063 fewer road traffic collisions with victims than expected, 2909 fewer deaths (57%) and 25 444 fewer hospitalizations. The estimated total cost savings were around €18 000 million. Of these, around 97% resulted from reductions in lost productivity. Of the remaining cost savings, 63% were associated with specialized health care, 15% with adapting to disability and 8.1% with hospital care.

CONCLUSION

The road safety policies implemented in Catalonia in recent years were associated with a reduction in the number of deaths and injuries from traffic collisions and with substantial economic benefits to society.

Evaluation of primary care: The "Primary Care Assessment Tools - Facility version" for the Spanish health system

OBJECTIVE

To obtain versions of the Primary Care Assessment Tools (PCAT)-Facility version to evaluate primary care (PC) in the Spanish context, and to analyze its feasibility, reliability and validity.

METHODS

Cultural adaptation was performed through the use of forward and backward translations into Spanish and Catalan, observations and opinions of a panel of experts, and cognitive interviews with target users (PC team managers). A pilot phase was carried out in a sample of 130 managers of PC teams in Catalonia. A post-test questionnaire was sent 4-5 months later to all 194 managers of PC teams in the Barcelona health region. Analysis of metric properties included: 1) description of items and verification of Likert assumptions, since domain scores are obtained by summing item scores; 2) reliability analysis (Cronbach's alpha coefficient, Pearson's correlation coefficient, test-retest analysis); and 3) validity analysis (expert panel, cognitive interviews, and convergent and discriminant validity).

RESULTS

Substantial adaptation was required for the accessory section of the questionnaire, but less was required in PC domain measurements. Items were added to the comprehensiveness domain to reflect services usually available in Spain. The lowest Cronbach's alpha scores were found for Access (0.62) and Coordination (0.59 and 0.65), while values were >0.70 for the remaining domains.

CONCLUSION

The Spanish version of the PCAT-Facility questionnaire is now available and shows adequate reliability and validity. The Spanish PCAT version will facilitate national and international comparisons of PC and analysis of the determinants of quality of service provision.

Spinal cord injury and traumatic brain injury: a cost-of-illness study

BACKGROUND

Among traumatic injuries, spinal cord injuries (SCI) and traumatic brain injuries (TBI) are of major importance because of their epidemiological and economic impact on society. The overall objective of this study was to estimate the economic cost associated with people with SCI and TBI in Spain in 2007.

METHODS

A cost-of-illness analysis was performed, considering the perspective of society, using a 1-year time horizon. Medical costs, adaptation costs, material costs, administrative costs, and costs of police, firefighters and roadside assistance, productivity losses due to institutionalization and sick leave, as well as an estimate of productivity losses of carers, and productivity losses due to death were included.

RESULTS

The economic cost associated with people with SCI is between EUR 92,087,080.97 and 212,496,196.41 (USD 131 million and 302 million) according to the injury mechanism, and between EUR 1,079,223,688.66 and 3,833,752,692.78 (USD 1,536 million and 5,458 million) for people with TBI.

CONCLUSIONS

There is an urgent need to develop effective interventions known to prevent SCI and TBI, and to evaluate their effectiveness and efficiency.

Coauthorship and institutional collaborations on cost-effectiveness analyses: a systematic network analysis

Background

Cost-Effectiveness Analysis (CEA) has been promoted as an important research methodology for determining the efficiency of healthcare technology and guiding medical decision-making. Our aim was to characterize the collaborative patterns of CEA conducted over the past two decades in Spain.

Methods and Findings

A systematic analysis was carried out with the information obtained through an updated comprehensive literature review and from reports of health technology assessment agencies. We identified CEAs with outcomes expressed as a time-based summary measure of population health (e.g. quality-adjusted life-years or disability-adjusted life-years), conducted in Spain and published between 1989 and 2011. Networks of coauthorship and institutional collaboration were produced using PAJEK software. One-hundred and thirty-one papers were analyzed, in which 526 authors and 230 institutions participated. The overall signatures per paper index was 5.4. Six major groups (one with 14 members, three with 7 members and two with 6 members) were identified. The most prolific authors were generally affiliated with the private-for-profit sector (e.g. consulting firms and the pharmaceutical industry). The private-for-profit sector mantains profuse collaborative networks including public hospitals and academia. Collaboration within the public sector (e.g. healthcare administration and primary care) was weak and fragmented.

Conclusions

This empirical analysis reflects critical practices among collaborative networks that contributed substantially to the production of CEA, raises challenges for redesigning future policies and provides a framework for similar analyses in other regions.

Incidence trends of traumatic spinal cord injury and traumatic brain injury in Spain, 2000-2009

AIMS

The aim of the present study was to estimate the incidence of hospital discharges for traumatic spinal cord injury (TSCI) and traumatic brain injury (TBI) in Spain by injury circumstances (traffic crashes and others), injury severity, gender and age group and to describe its trends over the period 2000-2009.

METHODS

It is a study of trends that includes hospital discharges with a primary diagnosis of TSCI or TBI. Crude and age-standardised rates were calculated per million inhabitants. Changes in rates between 2000 and 2009 were assessed through calculation of the relative risk adjusted for age, using Poisson regression.

RESULTS

Between 2000 and 2009 in Spain, 10,274 patients were admitted for traumatic TSCI, and 206,503 for TBI. The annual incidence rate for TSCI was 23.5 per million, that for TBI was 472.6 per million. The overall incidence rate for TSCI fell significantly between 2000 and 2009 by 24.2% (traffic-related 40.9%, other 12.9%), as did that for TBI (23.8% overall, 60.2% traffic-related, with no change for other circumstances). Among people aged 65 years and over, no change was observed for TSCI, incidence of TBI fell significantly when due to traffic crashes, but there was a dramatic increase of 87% in men and 89.3% in women when due to other circumstances.

CONCLUSIONS

Over the last decade the incidence of these types of injury has fallen significantly when the injury resulted from traffic crashes, and to a lesser extent when from other circumstances. However TBI incidence among people aged 65 and over injured in non-traffic-related circumstances has risen dramatically.

Health services utilization, work absenteeism and costs of pandemic influenza A (H1N1) 2009 in Spain: a multicenter-longitudinal study

BACKGROUND

The aim of this study was to estimate healthcare resource utilization, work absenteeism and cost per patient with pandemic influenza (H1N1)2009, from its beginning to March 2010, in Spain. We also estimated the economic impact on healthcare services.

METHODS AND FINDINGS

Longitudinal, descriptive, multicenter study of in- and outpatients with confirmed diagnosis of influenza A (H1N1) in Spain. Temporal distribution of cases was comparable to that in Spain. Information of healthcare and social resources used from one week before admission (inpatient) or index-medical visit (outpatient) until recovery was gathered. Unit cost was imputed to utilization frequency for the monetary valuation of use. Mean cost per patient was calculated. A sensitivity analysis was conducted, and variables correlated with cost per patient were identified. Economic impact on the healthcare system was estimated using healthcare costs per patient and both, the reported number of confirmed and clinical cases in Spain. 172 inpatients and 224 outpatients were included. Less than 10% were over 65 years old and more than 50% had previous comorbidities. 12.8% of inpatients were admitted to the Intensive Care Unit. Mean length of hospital stay of patients not requiring critical care was 5 days (SD = 4.4). All working-inpatients and 91.7% working-outpatients went on sick leave. On average, work absenteeism was 30.5 days (SD = 20.7) for the first ones and 9 days (SD = 6.3) for the latest. Caregivers of 21.7% of inpatients and 8.5% of outpatients also had work absenteeism during 10.7 and 4.1 days on average respectively. Mean cost was €6,236/inpatient (CI95% = 1,384-14,623) and €940/outpatient (CI95% = 66-3,064). The healthcare economic burden of patients with confirmed influenza was €144,773,577 (IC95% 13,753,043-383,467,535). More than 86% of expenditures were a result of outpatients' utilization.

CONCLUSION

Cost per H1N1-patient did not defer much from seasonal influenza estimates. Hospitalizations and work absenteeism represented the highest cost per patient.

[Social impact of abusive alcohol consumption in Spain: consumption, cost and policies]

Although it has declined in recent decades, alcohol consumption in Spain is still high compared with other European countries. The consumption pattern shows a converging trend with Europe, with a decrease in consumption of wine and an increase in the consumption of beer. Likewise, mortality related to alcohol consumption has also declined in the last twenty years, but remains a major cause of death. The direct healthcare costs and indirect costs of diseases totally and partially attributable to alcohol consumption in 2007 was 2669.74 million. The effective tax regime in Spain gravel alcohol very little, so a substantial increase, in line with some European countries, could be an option to be considered for accelerating the reduction of the burden of morbidity and mortality associated with alcohol consumption.
