Available on open access from BMC via the DOI in this recordAvailability of data and materials: The datasets are not available because researchers have signed an agreement with the Information System for the Development of Research in Primary Care (SIDIAP) concerning confidentiality and security of the dataset that forbids providing data to third parties. This organization is subject to periodic audits to ensure the validity and quality of the data.BACKGROUND: The purpose of this study was to ascertain multimorbidity patterns using a non-hierarchical cluster analysis in adult primary patients with multimorbidity attended in primary care centers in Catalonia. METHODS: Cross-sectional study using electronic health records from 523,656 patients, aged 45-64 years in 274 primary health care teams in 2010 in Catalonia, Spain. Data were provided by the Information System for the Development of Research in Primary Care (SIDIAP), a population database. Diagnoses were extracted using 241 blocks of diseases (International Classification of Diseases, version 10). Multimorbidity patterns were identified using two steps: 1) multiple correspondence analysis and 2) k-means clustering. Analysis was stratified by sex. RESULTS: The 408,994 patients who met multimorbidity criteria were included in the analysis (mean age, 54.2 years [Standard deviation, SD: 5.8], 53.3% women). Six multimorbidity patterns were obtained for each sex; the three most prevalent included 68% of the women and 66% of the men, respectively. The top cluster included coincident diseases in both men and women: Metabolic disorders, Hypertensive diseases, Mental and behavioural disorders due to psychoactive substance use, Other dorsopathies, and Other soft tissue disorders. CONCLUSION: Non-hierarchical cluster analysis identified multimorbidity patterns consistent with clinical practice, identifying phenotypic subgroups of patients.The project has been funded by the Instituto de Salud Carlos III of the Ministry of Economy and Competitiveness (Spain) through the Network for Prevention and Health Promotion in Primary Health Care (redIAPP, RD12/0005), by a grant for research projects on health from ISCiii (PI12/00427) and co-financed with European Union ERDF funds).

La participación ciudadana en la investigación desde la perspectivade investigadores de atención primaria

Objetivo: Explorar las debilidades, amenazas, fortalezas y oportunidades (DAFO) para el desarrollo de la participación de la ciudadanía en los proyectos de investigación gestionados por el Institut Universitari d'Investigació en Atenció Primària Jordi Gol (IDIAPJGol) según los investigadores de atención primaria de salud de Catalu ̃na.Método: Estudio transversal realizado en 2017 con 36 equipos de investigación de atención primaria de salud acreditados por el IDIAPJGol y su personal de gestión. Se dise ̃nó y pilotó un cuestionario abierto(papel y online) para desarrollar una técnica DAFO. Se obtuvieron 65 respuestas (14 en papel y 51 online).Se realizó un análisis de contenido temático.Resultados: La mayoría de informantes considera la participación de la ciudadanía en la investigació nuna estrategia útil, innovadora, viable e imprescindible, pero exige un cambio de mentalidad y un alejamiento del paradigma jerárquico. Puede ser difícil su ejecución y complicar los estudios. Les preocupa a qué ciudadanos implicar, cómo seleccionarlos, los posibles conflictos de intereses y las necesidades deformación. Las principales propuestas para su implementación son difundir estrategias previas, fomentar la motivación y las sinergias entre ciudadanos, investigadores e instituciones, y clarificar los roles delos actores implicados. El IDIAPJGol debería elaborar recomendaciones para la participación de la ciudadanía en la investigación, incentivar su inclusión, disponer de un referente y asesorar a los equipos investigadores. Conclusiones: A pesar de los retos, desarrollar la participación de la ciudadanía en la investigación en atención primaria de salud es imprescindible y factible, pero partiendo de una estrategia participativa con todos los actores. La ciudadanía puede participar en cualquier dise ̃no y fase de la investigación adaptando cada proyecto, siendo la atención primaria un ámbito privilegiado para desarrollar la participación ciudadana en la investigación.Objective: Explore the strengths, weaknesses, opportunities and threats (SWOT) for development of public involvement in research by Institut Universitari d'Investigació en Atenció Primària Jordi Gol (IDIAPJGol) according to primary health care researchers in Catalonia (Spain). Methods: Cross-sectional study carried out in 2017 with 36 primary health care research teams accredited by IDIAPJGol and its management staff. An open questionnaire (paper and online) was designed and piloted to develop a SWOT technique, and 65 answers were obtained (14 in paper and 51 online). A thematic content analysis was carried out. Results: Most informants consider public involvement in research a useful, innovative, viable and essential strategy, but it requires a change of mentality and a move away from the hierarchical paradigm. It can be difficult to execute and can complicate studies. They are concerned about which citizens should be involve, how to select them, possible conflicts of interest and training needs. The main proposals for its implementation are to disseminate previous strategies, encourage motivation and synergies among citizens, researchers and institutions, and to clarify the roles of the actors involved. IDIAPJGol should develop recommendations for the public involvement in research, encourage their inclusion, have a mentor and advise the research teams. Conclusions: Despite the challenges, developing public involvement in research in primary health care is essential and feasible, what it is more should be based on a participatory strategy with all actors. The citizens can participate in any kind of design and phase of the research, adapting each project, being the primary health care a privileged area to develop the public involvement in research

Multimorbidity Patterns in Elderly Primary Health Care Patients in a South Mediterranean European Region: A Cluster Analysis.

Published onlineJournal ArticleResearch Support, Non-U.S. Gov'tThis is the final version of the article. Available from Public Library of Science via the DOI in this record.OBJECTIVE: The purpose of this study was to identify clusters of diagnoses in elderly patients with multimorbidity, attended in primary care. DESIGN: Cross-sectional study. SETTING: 251 primary care centres in Catalonia, Spain. PARTICIPANTS: Individuals older than 64 years registered with participating practices. MAIN OUTCOME MEASURES: Multimorbidity, defined as the coexistence of 2 or more ICD-10 disease categories in the electronic health record. Using hierarchical cluster analysis, multimorbidity clusters were identified by sex and age group (65-79 and ≥80 years). RESULTS: 322,328 patients with multimorbidity were included in the analysis (mean age, 75.4 years [Standard deviation, SD: 7.4], 57.4% women; mean of 7.9 diagnoses [SD: 3.9]). For both men and women, the first cluster in both age groups included the same two diagnoses: Hypertensive diseases and Metabolic disorders. The second cluster contained three diagnoses of the musculoskeletal system in the 65- to 79-year-old group, and five diseases coincided in the ≥80 age group: varicose veins of the lower limbs, senile cataract, dorsalgia, functional intestinal disorders and shoulder lesions. The greatest overlap (54.5%) between the three most common diagnoses was observed in women aged 65-79 years. CONCLUSION: This cluster analysis of elderly primary care patients with multimorbidity, revealed a single cluster of circulatory-metabolic diseases that were the most prevalent in both age groups and sex, and a cluster of second-most prevalent diagnoses that included musculoskeletal diseases. Clusters unknown to date have been identified. The clusters identified should be considered when developing clinical guidance for this population.This study was supported by a grant from the Ministry of Science and Innovation through the Instituto Carlos III (ISCiii) in the 2012 call for Strategic Health Action proposals under the National Plan for Scientific Research, Development and Technological Innovation 2008–2011; by the European Union through the European Regional Development Fund (IP12/00427), as part of the Primary Care Prevention and Health Promotion Research Network (rediAPP), by ISCiii-RETICS (RD12/0005), by a 2011–2013 scholarship that aims to promote research in Primary Health Care by health professionals who have completed their specialty training, awarded by Institut Universitari d’Investigació en Atenció Primària Jordi Gol (IDIAP Jordi Gol), by a National Institute for Health Research Clinician Scientist Award (Jose M Valderas, NIHR/CS/010/024) and by a grant from the XIX call for research projects in the elderly population by Agrupació Mútua Foundation (Premio ámbito para las personas mayores, 2012).

Patrones de multimorbilidad en adultos jóvenes en Cataluña : un análisis de clústeres

Identificar los patrones de multimorbilidad en pacientes de 19-44 años atendidos en atención primaria en Cataluña en el año 2010. Estudio descriptivo transversal. Doscientos cincuenta y un centros de salud. Fueron 530.798 personas con multimorbilidad de 19-44 años. La multimorbilidad fue definida como la coexistencia de ≥2 diagnósticos de la Clasificación Internacional de Enfermedades registrados en la historia clínica informatizada. Los patrones de multimorbilidad fueron identificados a través de un análisis jerárquico de clústeres y descritos por sexo y grupos de edad (19-24 y 25-44 años). De las 882.708 personas de la población inicial, 530.798 (60,1%) presentaron multimorbilidad. La media de edad fue de 33,0 años (DT: 7,0) y el 53,3% fueron mujeres. La multimorbilidad fue más alta en el grupo de 25-44 años respecto al grupo más joven (60,5 vs. 58,1%, p < 0,001), siendo más alta en las mujeres. El clúster más prevalente en todos los estratos estuvo constituido por caries dental, tabaquismo, dorsalgia, resfriado común y otros trastornos de ansiedad. En ambos sexos, en los estratos de 25-44 años apareció el patrón cardiovascular-endocrino-metabólico (obesidad, dislipidemias e hipertensión arterial). La multimorbilidad afecta a más de la mitad de personas entre los 19-44 años de edad. El clúster más prevalente está formado por diagnósticos que agrupan enfermedades comunes (caries dental, resfriado común, tabaquismo, trastornos de ansiedad y dorsalgias). Otro patrón a destacar es el cardiovascular-endocrino-metabólico en el grupo de 25-44. El conocimiento de los patrones de multimorbilidad en adultos jóvenes permitiría un enfoque preventivo

Multiple health behaviour change primary care intervention for smoking cessation, physical activity and healthy diet in adults 45 to 75 years old (EIRA study): a hybrid effectiveness-implementation cluster randomised trial

Background: This study aimed to evaluate the effectiveness of a) a Multiple Health Behaviour Change (MHBC) intervention on reducing smoking, increasing physical activity and adherence to a Mediterranean dietary pattern in people aged 45–75 years compared to usual care; and b) an implementation strategy. Methods: A cluster randomised effectiveness-implementation hybrid trial-type 2 with two parallel groups was conducted in 25 Spanish Primary Health Care (PHC) centres (3062 participants): 12 centres (1481 participants) were randomised to the intervention and 13 (1581 participants) to the control group (usual care). The intervention was based on the Transtheoretical Model and focused on all target behaviours using individual, group and community approaches. PHC professionals made it during routine care. The implementation strategy was based on the Consolidated Framework for Implementation Research (CFIR). Data were analysed using generalised linear mixed models, accounting for clustering. A mixed-methods data analysis was used to evaluate implementation outcomes (adoption, acceptability, appropriateness, feasibility and fidelity) and determinants of implementation success. Results: 14.5% of participants in the intervention group and 8.9% in the usual care group showed a positive change in two or all the target behaviours. Intervention was more effective in promoting dietary behaviour change (31.9% vs 21.4%). The overall adoption rate by professionals was 48.7%. Early and final appropriateness were perceived by professionals as moderate. Early acceptability was high, whereas final acceptability was only moderate. Initial and final acceptability as perceived by the participants was high, and appropriateness moderate. Consent and recruitment rates were 82.0% and 65.5%, respectively, intervention uptake was 89.5% and completion rate 74.7%. The global value of the percentage of approaches with fidelity =50% was 16.7%. Eight CFIR constructs distinguished between high and low implementation, five corresponding to the Inner Setting domain. Conclusions: Compared to usual care, the EIRA intervention was more effective in promoting MHBC and dietary behaviour change. Implementation outcomes were satisfactory except for the fidelity to the planned intervention, which was low. The organisational and structural contexts of the centres proved to be significant determinants of implementation effectiveness. Trial registration: ClinicalTrials.gov, NCT03136211.

Patients' perceptions and experiences of patient safety in primary care in England

Background. One of the most remarkable features of patient safety research in primary care is the sparse attention paid to patients’ own experiences. Objective. To explore patient’s perceptions and experiences of patient safety in primary care in England. Methods. We conducted a qualitative study in the South of England with an opportunistic sample of 27 primary care users. Information was obtained from four patient focus groups. A thematic content analysis was conducted by three analysts and consensus reached within the research team on the key themes that emerged. Results. Participants’ conceptualizations of patient safety referred to high standards of health care delivery within a relationship of trust. Participants identified four main factors that they believed could potentially affect patient safety. These included factors related to (i) the patient (attitudes, behaviours and health literacy); (ii) the health professional (attitudes, behaviours and accuracy of diagnoses); (iii) the relationship between patients and health professionals (communication and trust); and (iv) the health care system (workload, resources, care coordination, accessibility, interdisciplinary teamwork and accuracy of health care records). Confidentiality, continuity of care and treatment-related safety emerged as cross-cutting major threats to patient safety. Conclusions. The exploration of participants’ perceptions and experiences allowed the identification of a wide variety of themes that were perceived to impact on patient safety in primary care. The findings of this study could be used to enrich current frameworks that are exclusively based on professional or health care system perspectives

Prevalencia de portadores nasales de Staphylococcus aureus y Streptococcus pneumoniae en atención primaria y factores asociados a la colonización [Prevalence of nasal carriage of Staphylococcus aureus and Streptococcus pneumoniae in Primary Care and factors associated with colonization.]

OBJECTIVE: To determine (i) the prevalence of Staphylococcus aureus (S.aureus) and Streptococcus pneumoniae (S.pneumoniae) nasal carriage in Primary Health Care patients in area of Barcelona, and (ii) the factors associated with S.aureus and S.pneumoniae colonization. METHODS: Multi-center cross-sectional study conducted in 2010-2011 with the participation of 27 Primary Health Care professionals. Nasopharyngeal swabs were obtained from 3,969 patients over 4 years of age who did not present with any sign of infection. Dependent variables: S.aureus and/or S.pneumoniae carrier state. Independent variables: socio-demographic characteristics, health status, vaccination status, occupation, and living with children. A descriptive analysis was performed. The prevalence of carriers of S.aureus and/or S.pneumoniae was calculated and logistic regression models were adjusted by age. RESULTS: In children from 4 to 14 years old, the prevalence of S.aureus carriers was 35.7%, of S.pneumoniae 27.1%, and 5.8% were co-colonized. In adults older than 14 years old, the prevalence was 17.8%, 3.5%, and 0.5%, respectively. In children, S.aureus carrier state was inversely associated with S.pneumoniae carrier state; S.pneumoniae was associated with younger age, and inversely associated with S.aureus carrier state. In adults, being a carrier of S.aureus was associated with male gender, younger age, and a health-related occupation, whereas S.pneumoniae carrier state was associated with living with children under 6 years of age. The proportion of co-colonized carriers was low (1.0%). CONCLUSIONS: The proportion of S.aureus and S.pneumoniae carriers was higher in children than in adults. Age was the only factor associated with healthy carrier status for S.aureus and for S.pneumoniae
