A Co-Design Process to Elaborate Educational Materials to Promote Appropriate Use of Antibiotics for Acute Lower Respiratory Tract Infections in Primary Healthcare in Catalonia (Spain).

PURPOSE: Co-design processes with patients allow developing health education materials, that are adapted to the population's knowledge and use of language, to reduce inappropriate antibiotic use. PATIENTS AND METHODS: This study presents a co-design process of educational material with patients (over 18 years old) with a previous diagnosis of acute lower respiratory tract infection. The co-design was framed within a qualitative study (Phase I, interviews; Phase II, focus group) conducted in Barcelona between April and September 2019. RESULTS: Twenty-nine semi-structured interviews were conducted. Six people participated in the focus group. Based on participants' narratives, educational materials can be useful to support healthcare consultations. Materials should be designed to be accessible in terms of the content and language used. CONCLUSION: The co-design of educational materials is essential for health promotion. This study presents an example of how materials can be co-developed with patients. The material elaborated in this study is being used for the ISAAC-CAT project and may be useful for future research, practice in health services and health policy.

Autonomy, power dynamics and antibiotic use in primary healthcare: A qualitative study.

Antibiotic resistance is a global health concern. Although numerous strategies have tried to reduce inadequate antibiotic prescribing, antibiotics are still prescribed in 60% of acute lower respiratory tract infections (ALRTIs) cases in Catalonia (Spain). This study aims to explore service users' experiences of ALRTIs, the quality and access to healthcare services, and health education. Selective purposive sampling was carried out, based on a prior definition of participant characteristics. These were sex, age, ethnicity, date of the last ALRTI, number of ALRTIs in the last year, and treatments received. Participants with a previous diagnosis of ALRTIs were recruited from three primary health care centres in Barcelona and one in Tarragona. Twenty-nine interviews were conducted between April and June 2019. A content thematic analysis was performed. Three themes were identified: 1) risk perceptions and help-seeking; 2) treatment preferences and antibiotic use; and 3) relationship dynamics and communication with healthcare professionals. Accounts of service users' sense of autonomy towards their health and power dynamics within the healthcare system were apparent. Supporting service users to become reliable, subjective and agentic experts of their health and bodies could help them to voice their healthcare agendas. Power structures embedded within healthcare, political and economic institutions should be challenged so that healthcare services can be co-developed (with service users) and based on service users' autonomy and horizontal relationships. Special consideration should be paid to the intersection of social vulnerabilities. A concordance approach to prescribing could be key to improve the responsible use of antibiotics and to contribute to the prevention of AMR in primary healthcare. The marketisation of health, and the increased demands of private healthcare in Spain due to the financial pressures on public healthcare as a consequence of the financial crisis of 2008 and the COVID-19 pandemic, are a risk for promoting adequate antibiotic prescribing and use. Trial registration The ISAAC-CAT study has been registered in the NCT registry, ID: NCT03931577.

Effectiveness and cost-effectiveness of Improving clinicians' diagnostic and communication Skills on Antibiotic prescribing Appropriateness in patients with acute Cough in primary care in CATalonia (the ISAAC-CAT study): study protocol for a cluster randomised controlled trial.

BACKGROUND: Despite their marginal benefit, about 60% of acute lower respiratory tract infections (ALRTIs) are currently treated with antibiotics in Catalonia. This study aims to evaluate the effectiveness and efficiency of a continuous disease-focused intervention (C-reactive protein [CRP]) and an illness-focused intervention (enhancement of communication skills to optimise doctor-patient consultations) on antibiotic prescribing in patients with ALRTIs in Catalan primary care centres. METHODS/DESIGN: A cluster randomised, factorial, controlled trial aimed at including 20 primary care centres (N = 2940 patients) with patients older than 18 years of age presenting for a first consultation with an ALRTI will be included in the study. Primary care centres will be identified on the basis of socioeconomic data and antibiotic consumption. Centres will be randomly assigned according to hierarchical clustering to any of four trial arms: usual care, CRP testing, enhanced communication skills backed up with patient leaflets, or combined interventions. A cost-effectiveness and cost-utility analysis will be performed from the societal and national healthcare system perspectives, and the time horizon of the analysis will be 1 year. Two qualitative studies (pre- and post-clinical trial) aimed to identify the expectations and concerns of patients with ALRTIs and the barriers and facilitators of each intervention arm will be run. Family doctors and nurses assigned to the interventions will participate in a 2-h training workshop before the inception of the trial and will receive a monthly intervention-tailored training module during the year of the trial period. Primary outcomes will be antibiotic use within the first 6 weeks, duration of moderate to severe cough, and the quality-adjusted life-years. Secondary outcomes will be duration of illness and severity of cough measured using a symptom diary, healthcare re-consultations, hospital admissions, and complications. Healthcare costs will be considered and expressed in 2021 euros (year foreseen to finalise the study) of the current year of the analysis. Univariate and multivariate sensitivity analyses will be carried out. DISCUSSION: The ISAAC-CAT project will contribute to evaluate the effectiveness and efficiency of different strategies for more appropriate antibiotic prescribing that are currently out of the scope of the actual clinical guidelines.

[Epidemiological surveillance activities during the 2009 influenza pandemic in Spain: lessons learnt one year after]. / Actividades de vigilancia epidemiológica durante la pandemia de gripe (H1N1) 2009 en España: Reflexiones un año después.

In this article the actions taken in the area of epidemiological surveillance in Spain during the influenza pandemic and the recommendations drawn from them during the progression of the pandemic are reviewed. The performance of the Surveillance Subcommittee established in the National Influenza Preparedness and Response Plan was central to the coordination of these activities. The Surveillance Subcommittee was immediately activated when the alert was issued. Its role is also described in this review. The existence of a National Plan allowed a rapid and coordinated response after the alert declaration. The epidemiological and virological surveillance of the influenza pandemic was adapted to an evolving situation. In addition to routine influenza monitoring systems, new surveillance systems were put in place such as a case-based surveillance for community influenza cases and a case-based surveillance for severe cases and deaths due to the pandemic. Among the lessons learned from this pandemic, we would highlight the need to strengthen the timely analysis of data collected during an alert, the need to promote the exchange of information among public health and health care professionals, and to strengthen the response capacity in order to have resilient and consolidated public health structures for future health alerts.

[Enhanced surveillance of initial cases of pandemic influenza (H1N1) 2009 infection in Spain, April-June 2009]. / Vigilancia individualizada de los casos iniciales de infección por gripe pandémica (H1N1) 2009 en España, Abril-Junio 2009.

BACKGROUND: In April 2009, a new surveillance strategy for the detection of cases of pandemic influenza (H1N1) 2009 infection and for the implementation of appropriate control measures to contain its transmission was initiated in Spain. We describe the clinical and epidemiological characteristics of confirmed cases in Spain notified by the National Epidemiological Surveillance Network from April 24 to June 30, 2009. METHODS: As part of the initial surveillance response to the pandemic, case-based clinical and epidemiological information was collected nationwide on cases under investigation for pandemic virus (H1N1) 2009 infection and their contacts. RESULTS: Of 717 confirmed cases, 91% were notified by 5 Autonomous Communities. As of June 15,49.1% of cases belonged to school outbreaks. No nosocomial outbreaks were detected. The median incubation period was 3 days. Eighty-eight percent of cases were under the age of 30 years, and 24.9% were imported. The most frequent symptoms were cough (92%) and fever (81.8%). The median duration of symptoms was 5 days. Thirteen cases required hospitalization and one died. CONCLUSIONS: During the first months of the pandemic, pandemic influenza cases experienced a mild illness similar to seasonal influenza, predominantly affecting children and young adults. By the end of June 2009, the detection of outbreaks in different settings indicated the diffusion of the pandemic virus into the community and the start of its circulation.

[Critically ill patients with 2009 pandemic influenza A (H1N1) infection in Spain: factors associated with death, April 2009-January 2010]. / Casos de infección por gripe pandémica (H1N1) 2009 hospitalizados en cuidados intensivos en España: factores asociados a riesgo de muerte, Abril 2009-Enero 2010.

BACKGROUND: It is necessary to analyse the severe cases of pandemic influenza infection in order to identify vulnerable populations and adapt prevention and control policies accordingly. We analysed the clinical and epidemiological characteristics and risk factors associated with death in patients with 2009 pandemic influenza A (H1N1) infection hospitalised in intensive care units (ICUs) in Spain and reported from 24 April 2009 to 31 January 2010. METHODS: As part of the national strategy for surveillance of hospitalized cases with pandemic influenza, cased-based clinical and epidemiological information on all cases admitted to an ICU with 2009 pandemic virus (H1N1) infection was collected nationwide. RESULTS: Of 1,231 cases admitted to ICU, 271 died (case fatality ratio, 22%). The median age was 40 years (range: 0-90). A total of 838 (76.3%) patients had an underlying risk condition, being respiratory disease the most frequently reported (34.1%), followed by morbid obesity (18.8%), in adults. Antiviral treatment was given in 93.1% patients and in 25.6% (n = 231) it was initiated within 48 hours of symptoms onset. In a multivariate analysis, cancer (OR 2.71, 95%CI 1.44 to 5.1), immunodeficiency (OR 2.25, 95%CI 1.29 - 3.92) and morbid obesity (OR 1.79, 95%CI 1.13 to 2.85) were significantly associated with death in adults. CONCLUSIONS: The characterization of severe pandemic influenza cases has been crucial in identifying as risk factors of complications and death from influenza the presence of cancer and immunodeficiencies and for the first time, morbid obesity in adults.

Evolution of anti-influenza vaccination coverage in Spain from 1993 to 2001.

UNLABELLED: The objective of this study is to describe the evolution of anti-influenza vaccination coverage in Spain from 1993 to 2001. We analysed 55,040 questionnaires taken from the Spanish National Health Surveys from the years 1993, 1995, 1997 and 2001. The reply to the question "Did you vaccinate yourself against influenza during the last campaign?" is the dependent variable. Independent variables were the year of the survey, age, sex and the coexistence of chronic conditions. After adjusting using logistic regression, we found a significant improvement during the study period among those subjects at risk of suffering complications from influenza (OR 1.21). Nevertheless, this increase was essentially at the cost of subjects aged 65 and over. Subjects with high-risk conditions under 65 did not undergo significant changes. CONCLUSIONS: A significant but insufficient improvement has been achieved and this must lead us to consider the possible need to modify anti-influenza vaccination recommendations.

[Evolution of the degrees of influenza vaccine (flu shot) coverage in Spain throughout the 1993-2001 period. Analysis by Autonomous Communities]. / Evolución de las coberturas vacunales antigripales entre 1993-2001 en España. Análisis por Comunidades Autónomas.

BACKGROUND: Influenza (flu) is a disease involving a high morbidity which takes a high toll on healthcare costs for which there is an effective vaccine available. This study is aimed at evaluating the evolution of the different degrees of influenza vaccine (flu shot) coverage in Spain by Autonomous Communities during the 1993-2001 period. METHODS: A total of 42,123 cases from the National Health Survey (NHS) for the years 1993 (n=21,051) and 2001 (n=21,072) were analysed, all of which corresponded to non-institutionalised Spanish adults over 15 years of age. Both surveys are representative at the Autonomous Community level. RESULTS: For the total sample, a vaccine coverage of 17.94% (CI 95% 17.42-18.46) in 1993 and of 19.30% (18.77-19.83) en 2001 was estimated. In the logic regression model, adjusted by age, sex and related chronic disease, significant improvements were found in the degrees of coverage of individuals over 64 years of age (OR = 1.28 CI 95% 1.10-1.50) for Spain as a whole and for five of the seventeen Autonomous Communities between 1993 and 2001. However, no significant changes were found in the degrees of coverage for the group under age 65 with related chronic disease entailing an indication for being administered the vaccine. CONCLUSIONS: A slight yet insufficient improvement in the degrees of coverage among the high-risk groups studied were found to exist both nation-wide in Spain as a whole as well as in the majority of the Autonomous Communities between 1993 and 2001. Degrees of coverage varied greatly among Autonomous Communities. The individual under age 65 with related chronic diseases heightening the risks of suffering from flu-related complications have not improved their degrees of coverage regarding this vaccine during the period studied. The difficulty involved in improving the degrees of coverage among this type of patients might lead us to consider the alternative and potential benefit of lowering the age limit of the current influenza vaccine (flu shot) indication-related recommendations in Spain.

[A study of whooping cough epidemic outbreak in Castellon, Spain]. / Estudio de un brote epidémico de tos ferina en Castellón.

BACKGROUND: Based on the report of several cases at one school, a study of an epidemic outbreak was started for the purpose of characterizing this outbreak from the person, place and time standpoint, calculating the effectiveness of the immunization and the concordance of the cases with the positive result of the serological study. METHODS: A "case" is defined as being that individual who has a cough fasting for two weeks. A study is made of the spread of the disease by means of the epidemic curve and the effectiveness of the pertussis vaccine. The concordance of the cases and the positive serology is evaluated by way of the Kappa index. RESULTS: From among the students at several schools and those with whom they were living at the time, a total of 130 individuals were surveyed, 94 of whom fit the "case" definition. The average age of the cases was 10.5 years of age, 42.6% being males and 84% school age children, 71.3% showing signs of recent infection (positive IgM), the average length of time since the last whooping cough immunization being 8.25 years. The effectiveness of the whooping cough booster is 66%. The concordance between the cases and the positive results of the serology reveals a Kappa = 0.45. No B. Pertussis was isolated in the 25 throat swab samples. CONCLUSIONS: Classrooms and the family environment are a factor in spreading this disease. The including of a booster at 18 months improves the effectiveness of the whooping cough immunization. The isolation of B. Pertussis is not very frequent, and the serology may be an alternative when this disease is clinically suspected.
