What do Spaniards read about the prudent use of anti-microbial agents and what do they really do?

OBJECTIVES: The prudent use of antibiotics (PUA) is promoted not only by public information campaigns, but also in the printed media and on websites. This study assesses the correspondence between PUA information in the Spanish printed media and on websites and the messages put out by national campaigns. Spaniards' use of antibiotics following the campaigns was also analysed. METHODS: A two-phase descriptive study was carried out. First, antibiotics-related news in the Spanish printed media (January 2007-May 2009) and institutional and news media websites (March-May 2009) were systematically reviewed using a data collection tool. In addition, a telephone survey on antibiotics-related knowledge and behaviours was carried out with a random sample of 1526 people living in Spain who had recently received medical care. RESULTS: In total, 29 news items containing nine different messages were identified. All the messages were similar to those promoted by the campaigns. The survey showed that even after the campaigns, relevant gaps in knowledge about the PUA persist, particularly among men (p = .005), those living in rural areas (p = .02) and the elderly (p < .001). Keeping left-over antibiotics was associated with ignorance about the association between antibiotic use and resistance (OR 3.1, 95% CI 2.3-4.2). Also, patients who ask their doctor about drug interactions are less likely to self-medicate (p = .04). CONCLUSIONS: The information reaching the Spanish public via the media seems to be similar to the messages transmitted by public information campaigns. Nevertheless, there appears to be considerable room for improvement. Promoting an active role in patients might reduce self-medication.

Loneliness impact on healthcare utilization in primary care: A retrospective study.

BACKGROUND: An increased number of patients seek help for loneliness in primary care. OBJECTIVE: To analyze whether loneliness was associated with a higher utilization of healthcare facilities. METHODS: Observational, retrospective study based on the review of routinely coded data in the digital medical record system in a random sample of patients aged 65 or older, stratified by population size of their residence area. A minimum sample size was estimated at 892 medical records. Loneliness was defined as the negative feeling that arises when there is a mismatch between the quantity and quality of a person's social relationships and those, they desire. Thirty-three primary care nurses (30 females and 3 males) were reviewing the data. RESULTS: A total of 932 medical records of patients were reviewed (72% belonged to female patients). Of these, 657 individuals were living alone (71.9%). DeJong Scale average scores was 8.9 points (SD 3.1, 95CI 8.6-9.1). The average annual attendance to primary care ranged from 12.2 visits per year in the case of family practice, 10.7 nurse, 0.7 social workers. The average number of home visits was 3.2, and the urgent consultations attended at health centers were 1.5 per year. Higher feelings of loneliness were associated with extreme values in the frequency of healthcare resource usage. Compared to their peers of the same age, the additional healthcare resource consumption amounted to €802.18 per patient per year. CONCLUSION: Loneliness is linked to higher healthcare resource usage in primary care, with individuals experiencing poorer physical and mental health utilizing these resources up to twice as much as their peers of the same age.

Social Prescribing Schemes in Primary Care in Spain (EvalRA Project): a mixed-method study protocol to build an evaluation model.

BACKGROUND: Social Prescribing is a Primary Health Care service that provides people with non-clinical care alternatives that may have an impact on their health. Social Prescribing can be more or less formal and structured. Social Prescribing Schemes are formal Social Prescribing of health assets by Primary Health Care teams in coordination and follow-up of patients with providers. The emerging evidence suggests that this service can improve people's health and well-being, create value and provide sustainability for the healthcare system. However, some evaluations note that the current evidence regarding social prescribing is insufficient and needs further investigation. The EvaLRA project aims to elaborate an evaluation model of Social Prescribing Schemes in Primary Health Care based on a set of structure, process, and outcomes indicators. METHODS: In the region of Aragon, the Community Health Care Strategy aims to promote the development of social prescription schemes in Primary Health Care teams. This study is divided into two stages. Stage 1: identification of primary health care teams that implement social prescribing schemes and establish a first set of indicators to evaluate social prescribing using qualitative consensus techniques with experts. Stage 2 evaluation of the relevance, feasibility and sensitivity of selected indicators after 6 and 12 months in primary health care teams. The results will provide a set of indicators considering structure, process and outcomes for social prescribing schemes. DISCUSSION: Current evaluations of the application of social prescribing schemes use different criteria and indicators. A set of agreed indicators and its piloting in primary health care teams will provide a tool to evaluate the implementation of social prescription schemes. In addition, the scorecard created could be of interest to other health systems in order to assess the service and improve its information system, deployment and safety.

What makes hospitalized patients more vulnerable and increases their risk of experiencing an adverse event?

OBJECTIVE: To analyze the relationship between the appearance of adverse events (AEs) and both patient comorbidities and the use of medical devices. DESIGN: Retrospective medical records review study. SETTING: Twenty-four Spanish public hospitals. PARTICIPANTS: Clinical records of 5624 discharged patients. MAIN OUTCOME MEASURE: Incidence of AEs. RESULTS: Patients aged >65 have 2.4 times the risk of experiencing an AE compared with those aged <65. The presence of certain comorbidities and devices (neoplasia, chronic hepatic alteration, cardiac insufficiency, coronary disease, high blood pressure, urethral catheterization, catheterization of a vessel, tracheostomy or stay of >7 days) were associated with developing an AE during hospitalization. There is a trend effect if we consider the number of comorbidities and the number of devices used. Thus, the risk of an AE in subjects who present no comorbidities was 3.2%, which rose to 9.9% in those with one intrinsic risk factor, 16.7% in those with two and 29.3% in those with three or more. Similarly, subjects without extrinsic risk factor experienced an AE in 4.4% of cases, which rose to 9.6% when there was one risk factor, to 13.4% when there were two and to 33.0% when there were three or more risk factors. The effect of some of these pathologies and that associated with age disappeared on adjusting in line with other variables. CONCLUSIONS: The true risk resides in the number of exposures to potentially iatrogenic actions, rather than being intrinsic to age or the presence of certain comorbidities.

Frequency of outpatient care adverse events in an occupational mutual insurance company in Spain.

BACKGROUND: Occupational mutual insurance companies (OMICs), in collaboration with the Spanish Social Security System, provide healthcare and manage the economic benefits for the workers in Spain. They have ambulatory care centers that attend outpatient trauma pathology, although most of the studies published have focused on surgical and hospital activity. The aim of this study was to detect adverse events (AEs) in outpatient trauma care in the context of an OMIC. METHODS: A cohort study designed to identify harmful safety incidents (adverse events, AEs) in 2017 was conducted. A random sample of 313 medical records among patients who were visited more than 3 medical and nursing attendances during their outpatient process. The AEs detected were classified according to category, severity and preventability. RESULTS: We identified 48 AEs (15.3% of medical records, 95% CI 11.3-19.3), most of them procedure-related, while 27 (56.2%) were preventable and 46 mild (95.8%). CONCLUSIONS: The AEs identified are double than those found in primary care general consultations in Spain and are close to the lower range of studies on surgical AEs in traumatology and orthopedics. Preventable AEs were within expected limits. Over half of AEs are preventable, within that group, the mild AEs have an increased rate of preventability. These results highlight the relevance of research of patient safety in the outpatient care of trauma and orthopaedic procedures in an OMIC for patient safety and contribute to introduce improvements in outpatient care.

[Outcome of complaints by patients due to the refusal of Primary Care Physicians to agree to a treatment request]. / Reclamaciones por la negativa del médico de primaria a aceptar una petición del paciente.

OBJECTIVE: To analyse the frequency of complaints due to the refusal of Primary Care Physicians to indicate a diagnostic test, treatment, or referral requested by a patient. METHODS: Observational, retrospective study was conducted by analysing the complaints filed in a Primary Care Area during the years 2016, 2017, and 2018. RESULTS: A total of 378 complaints were included. Of these, 30 (8%) were justified in the refusal by the doctors to a request of the patient (28 addressed to general practitioners and 2 to paediatricians). The most frequent related to the request was for a treatment (18 [60%]) followed by the request for diagnostic tests (9 [30%]). While the total number of claims increased by 151%, the relative weight of the claims for not responding to a patient's request was reduced (2016, 8/70, 11.4%; 2017, 11/132, 8.3%; and 2018, 11/176, 6.3%). No professional liability claims were filed. CONCLUSIONS: Complaints for rejecting patient requests increased slightly, but tends to decrease their relative weight when considering the volume of complaints.

[Specialised headache units, a feasible alternative in Spain]. / Unidades especializadas de cefalea, una alternativa viable en España.

INTRODUCTION: Visits due to headaches are the most frequent cause of demand for neurological treatment in primary care and neurology services. Headache units improve the quality of care, reduce waiting lists, facilitate access to new treatments of proven efficacy and optimise healthcare expenditure. However, these units have not been implemented on a widespread basis in Spain due to the relatively low importance attributed to the condition and also the assumption that such units have a high cost. AIM: To define the structure and minimum requirements of a headache unit with the intention of contributing to their expansion in hospitals in Spain. SUBJECTS AND METHODS: We conducted a consensus study among professionals after reviewing the literature on the structure, functions and resources required by a headache unit designed to serve an area with 350,000 inhabitants. RESULTS: Eight publications were taken as a reference for identifying the minimum resources needed for a headache unit. The panel of experts was made up of 12 professionals from different specialties. The main resource required to be able to implement these units is the professional staff (both supervisory and technical), which can mean an additional cost for the first year of around 107,287.19 euros. CONCLUSIONS: If we bear in mind the direct and indirect costs due to losses in labour productivity per patient and compare them with the estimated costs involved in implementing these units and their expected results, everything points to the need for headache units to become generalised in Spain.

TITLE: Unidades especializadas de cefalea, una alternativa viable en España.Introducción. Las consultas por cefalea son el motivo más frecuente de demanda de atención de causa neurológica en la atención primaria y en los servicios de neurología. Las unidades de cefalea mejoran la calidad asistencial, reducen las listas de espera, facilitan el acceso a nuevos tratamientos de eficacia contrastada y optimizan el gasto sanitario. No obstante, la implantación de estas unidades no está extendida en España debido a la relativa importancia atribuida a la patología y a la suposición de que su coste es elevado. Objetivo. Definir la estructura y los requerimientos mínimos de una unidad de cefalea con la intención de contribuir a su extensión en los hospitales de España. Sujetos y métodos. Estudio de consenso entre profesionales tras la revisión de la bibliografía sobre la estructura, las funciones y los recursos de una unidad de cefalea para un área de 350.000 habitantes. Resultados. Se tomaron como referencia ocho publicaciones para la identificación de recursos mínimos necesarios de una unidad de cefalea. El panel de expertos estuvo integrado por 12 profesionales de diferentes especialidades. El principal recurso para la implementación de estas unidades son profesionales (superiores y técnicos), lo que puede suponer un coste adicional para el primer año de alrededor de 107.287,19 euros. Conclusiones. Si consideramos los costes directos e indirectos debidos a las pérdidas por productividad laboral por paciente y los comparamos con los costes estimados de implantación de estas unidades y su expectativa de resultados, todo apunta a que es necesaria la generalización de unidades de cefalea en España.

Bed 13 is not worse than any other. A retrospective cohort study.

INTRODUCTION: Risk management and patient safety are closely related, following this premise some industries have adopted measures to omit number 13. Healthcare is not left behind, in some hospital the day of surgery's or bed numbering avoid number 13. The objective was to assess whether it is necessary to redesign the safety policies implemented in hospitals based on avoiding 13 in the numbering of rooms/beds. METHODS: A retrospective cohort study was conducted. Mortality and the number of adverse events suffered by patients admitted to rooms/beds numbering 13 (bad chance) or 7 (fair chance) over a two-year period to Intensive Care Unit, Medicine, Gastroenterology, Surgery, and Paediatric service were registered and compared. RESULTS: A total of 8553 admissions were included. They had similar length-of-stay and Charlson Index scores (p-value=0.435). Mortality of bed 13 was 268 (6.2%, 95% CI 5.5-6.9) and 282 in bed 7 (6.7%, 95% CI 5.9-7.5) (p-value=0.3). A total of 422 adverse events from 4342 admissions (9.7%, 95% CI 8.9-10.6) occurred in bed 13, while in bed 7 the count of adverse events was 398 in 4211 admissions (9.4%, 95% CI 8.6-10.4) (p-value=0.6). Odds Ratio for mortality was equal to 0.9 (95% CI 0.8-1.1) and suffering adverse events when admitted to bed 13 versus bed 7 was 1.03 (95% CI 0.9-1.2). CONCLUSIONS: Bed 13 is not a risk factor for patient safety. Hospitals should pay attention to causes and interventions to avoid adverse events based on evidence rather than beliefs or myths.

A comparison of websites from Spanish, American and British hospitals.

OBJECTIVE: To evaluate and compare the user-orientation of Spanish, American and British hospital websites. METHODS: A descriptive study of 32 hospital portals (12 Spanish, 10 American and 10 British) was carried out in which the following were analyzed: website readability according to the Flesch Index, websites accessibility using the Web Accessibility Test, and the quality of information provided using the "e-Information Scale of Health Care Centers". RESULTS: Fifty percent of the user-oriented information quality attributes are met. Readability indices tend to be below 60 (standard readability), and only 10 of the 32 websites meet the accessibility criteria. CONCLUSIONS: Most portals exhibit accessibility problems that favor computer illiteracy. There is a wide variability in terms of website readability and in terms of user-oriented content.

[Perceptions of clinical safety after hospital discharge]. / Percepción de seguridad clínica tras el alta hospitalaria.

OBJECTIVE: Patient perception of clinical safety has been scantly studied. This study describes the frequency of clinical errors from a patient point of view, their perception of safety and its relationship with the information received. MATERIAL AND METHODS: Descriptive study based on a postal survey to 336 surgical patients, 20 days after the discharge from the hospital (the corrected rate of response is 75.58%, the error is 5.7% for a confidence level of 95%). RESULTS: In the responses, 13.05% (95% CI, 9.16-16.95%) reported suffering a clinical error. Of these, 10.5% had severe complications. This experience decreases the perception of safety in future treatments (p = 0.0001). The risk of being a victim of a medical error with serious consequences is high was considered by 11.9% (95% CI, 7.2-16.6%) of the patients, although less than suffering from a traffic accident, a robbery or a serious illness. A higher frequency in the media related to medical mistakes, decreases the perception of safety (p < .001). The patients who positively value the information received regarding the treatment and who can formulate questions to ask the doctor are those who report less errors (p < .001). CONCLUSIONS: A total of 1.37% of surgical patients report mistakes with severe consequences, whereas 12% believe that the risk of a mistake with serious consequences is high. Distrust increases after an error. Improving communication with the patient helps to reduce mistakes, which strengthens the role of programs to increase safety that encourage more active patient involvement.

Habits of Internet users and usefulness of websites in Spanish for health education.

OBJECTIVE: To analyse whether websites in Spanish are an adequate medium to be self-informed considering the surfing styles of Internet users. METHODS: In a real context 225 subjects searched for information on the Net to answer a series of questions on two diseases and one therapeutic technique. Also, they informed their habits when using Internet. RESULTS: Slightly more than the half of the questions were correctly answered. To find information, they visited more than 70 different pages in all cases. A major number of websites visited was not related with a better knowledge of treatment or illness (p>0.05). CONCLUSIONS: When health professionals recommend a website to a patient (web prescription) they must consider both, the quality of the information, and the style for surfing on the Net.

[The perception of care received by patients with actinic keratosis]. / La percepción del proceso asistencial de pacientes con queratosis actínica.

OBJECTIVE: To analyse barriers limiting an integral approach in the care process of patients with actinic keratosis, and to validate a questionnaire of their perception in order to assess this approach. METHOD: A qualitative study (Focus Group) was conducted to assess the perception of the healthcare process of professionals (dermatologists, family doctors, nurses, pharmacists and managers), and patients. A validation study of a new tool was conducted, defining the scope and contents of a questionnaire of perceived quality. Reliability, consistency and validity were analysed after inviting a convenience sample of 225 patients to respond. RESULTS: Underdiagnosis in primary care, a higher variability in resources, and access to the health care circuit, together with gaps in patient information about actinic keratosis, are relevant barriers to achieve comprehensive care in this disease condition. The result of the focus groups advised to elaborate 14 reactive items. A total of 224 patients responded (mean age 71.6, SD 11.1), of which 153 (68%) were men. Two factors were isolated including 12 items (explained variance of 58%). The consistency of this factorial solution was .87, the split-half reliability being .76, with the scores in the factors showing an adequate predictive capacity. CONCLUSIONS: The coordination between levels and to reduce to variability in equipment and clinical decision making in Primary Care are the most prominent barriers. The questionnaire has appropriate metric properties and it explores the information and care by the medical staff and the information and advice provided by the pharmacist.

[Public participation in health. A review of reviews]. / La participación ciudadana en salud. Revisión de revisiones.

BACKGROUND: This study aims to synthesize knowledge about the role of the public's participation in the definition, prioritization, rationalization, monitoring or control of policies, plans, governance, investment/disinvestment, and design of health services. METHODS: Review of review articles (narrative or systematic) about consumer participation indexed in PubMed until August 2016. RESULTS: Forty-two reviews were identified (eighteen systematic and twenty-four narrative). The extent of participation was provincial/regional or national. The issues addressed covered: What is public participation? What benefits are expected? Who participates in the representation of citizens? How and to what extent do citizens participate and with what outcomes? The impact of public participation has hardly been studied. CONCLUSIONS: There is moderate evidence in support of the argument that public participation legitimizes decisions of the Health Authorities, and improves outcomes of health policies. There is consensus on how participation techniques should be applied but there is a need to inquire more deeply into the level of impact of this participation.

[Quality of care and safety indicators in anticoagulated patients with non-valvular auricular fibrillation and deep venous thromboembolic disease]. / Indicadores de calidad y seguridad en el paciente anticoagulado con fibrilación auricular no valvular y enfermedad tromboembólica venosa profunda.

OBJECTIVES: To identify and prioritise indicators to assess the quality of care and safety of patients with non-valvular auricular fibrillation (NVAF) and deep vein thrombosis (DVT) treated with anticoagulants. MATERIALS AND METHODS: Using the consensus conference technique, a group of professionals and clinical experts, the determining factors of the NVAF and DVT care process were identified, in order to define the quality and safety criteria. A proposal was made for indicators of quality and safety that were prioritised, taking into account a series of pre-established attributes. The selected indicators were classified into indicators of context, safety, action, and outcomes of the intervention in the patient. RESULTS: A set of 114 health care and safety quality indicators were identified, of which 35 were prioritised: 15 for NVAF and 20 for DVT. About half (49%) of the indicators (40% for NVAF and 55% for DVT) applied to patient safety, and 26% (33% for NVAF and 20% for DVT) to the outcomes of interventions in the patient. CONCLUSIONS: The present work presents a set of agreed indicators by a group of expert professionals that can contribute to the improvement of the quality of care of patients with NVAF and DVT treated with anticoagulants.

[Design of a thromboprophylaxis care process in patients with atrial fibrillation]. / Diseño del proceso asistencial de profilaxis de la tromboembolia en pacientes con fibrilación auricular.

OBJECTIVE: To describe the milestones in the anticoagulant care process of atrial fibrillation patients (AF), as well as quality and safety indicators, in order to establish an integrated care process of these patients in the Community of Madrid. METHODS: A consensus conference technique was applied, with the participation of 21 professionals (seven in the Steering Group and 14 known experts), from the specialties of Emergency, Internal Medicine, Cardiology, Neurology, Haematology, Family Medicine, Nursing, and Quality. Hospitals and Primary Care were represented. Milestones, elements and barriers/limitations were agreed upon in the care process of anticoagulated AF patients. A minimum set of indicators were also defined to assess the quality of care. RESULTS: Four milestones (stratification of thromboembolism and bleeding risk, evaluation for anticoagulant treatment, follow-up of direct-acting oral anticoagulants, and follow-up of treatment with vitamin K antagonists) were identified. A total of 14 barriers/limitations were also prioritised. In total, six indicators were defined (two structural-related, two processes-related, and two outcomes-related). CONCLUSIONS: Milestones and critical activities, together with a set of indicators, have been agreed for the development of guidelines with which to achieve a better therapeutic approach for anticoagulated AF patients.

[Level of knowledge of Quality Commitment Campaign and of "do not do" recommendations amongst general practitioners, pediatricians and nurses Primary Care]. / Grado de conocimiento de la campaña Compromiso por la Calidad y de las recomendaciones no hacer entre médicos de familia, pediatras y enfermería de Atención Primaria.

BACKGROUND: To evaluate if the Quality Commitment Campaign (QCC) was sufficiently known among primary care professionals (PC), and second, to evaluate the knowledge about certain recommendations of what should not be done in PC. METHODS: A observational study was conducted. General practitioners (GP), pediatricians (PED) and nursing (NUR) participated. A direct question was asked about whether QCC was known and a set of dichotomous questions based on the "do not do" recommendations to assess their knowledge. A sample size of 288 professionals from each group was the minimum required for a sampling error of 5%, 95% confidence level and p=0.75. The field study was conducted with the collaboration of health services and professional and scientific organizations. Data were described by frequencies and mean (standard deviation), and compared by means of ?2/Fisher or ANOVA and t-test. RESULTS: A total of 1,904 professionals (936 GP, 682 PED and 286 NUR) answered. The QCC initiative was known by 828 (43.5%) professionals: 524 (56.0%) GP, 234 (34.3%) PED and 70 (24.5%) NUR (p<0.001). All the questions were correctly answered by 652 (69.7%) GP, 631 (92.5%) PED and 116 (40.6%) NUR. Significantly more mistakes (p<0.001) were made by those who did not know the QCC, worked in the private sector or were not considered responsible for overuse. Despite not knowing the QCC, 60% GP and 90% PED answered all the questions of the test correctly. CONCLUSIONS: NUR and GP could benefit from a greater diffusion of the QCC. As could those working in the private sector and those who believe that professionals have little responsibility for unnecessary overuse.
