Daily time spent on screens and psychological well-being: Cross-sectional association within the SUN cohort.

BACKGROUND: The impact of various lifestyles on psychological well-being (PWB) remains under-studied. We aimed to explore the cross-sectional association between daily screen use (television, tablet and mobile phone) and PWB within the SUN cohort. METHODS: PWB was assessed using the 29-item Ryff scale (ranging from 29 to 174), and participants with scores >75th percentile were considered as having optimal PWB. Participants were categorized based on their self-reported weekly screen usage hours. Postestimation logistic regression models assessing the prevalence likelihood of not achieving optimal PWB were adjusted for sociodemographic, psychological, personality and lifestyles factors. Isotemporal substitution models explored the potential impact on PWB resulting from replacing 1 h/day of screen time with 1 h/day of exercise. RESULTS: The study included 3051 participants (55.8% women, mean age 57.3 ± 11.1 years, mean Ryff's score: 139.1 ± 17.4 points). Daily screen use for ≥2 h was associated with a higher prevalence likelihood of not achieving an optimal PWB (Prevalence Ratio [PR]:1.09; 95% CI:1.01-1.18). Among PWB dimensions, screen use ≥2 h/day was linked to an increased likelihood of not achieving optimal scores in environmental mastery (PR:1.11; 95% CI:1.02-1.20), life purpose (PR:1.10; 95% CI:1.02-1.18), and personal growth (PR:1.09; 95% CI:1.01-1.18). Replacing 1 h of daily screens time with 1 h of exercise may lead to potential improvements in environmental mastery (Odds Ratio [OR]:0.87; 95% CI:0.76-0.99), purpose in life (OR:0.86; 95% CI: 0.76-0.98), personal growth (OR:0.84; 95% CI:0.73-0.96) and positive interpersonal relationships (OR:0.86; 95% CI:0.75-0.99). CONCLUSIONS: These findings highlight the importance of reducing screen use activities and increasing physical exercise for achieving optimal PWB.

Behavioral and Personal Characteristics Associated With Risk of SARS-CoV-2 Infection in a Spanish University Cohort.

The aim of this study was to analyze the life habits and personal factors associated with increased severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) risk in a university environment with in-person lectures during the coronavirus disease 2019 (COVID-19) pandemic. To our knowledge, there are no previous longitudinal studies that have analyzed associations of behavioral and personal factors with the risk of SARS-CoV-2 infection on an entire university population. A cohort study was conducted in the 3 campuses of the University of Navarra between August 24, 2020, and May 30, 2021, including 14,496 students and employees; the final sample included 10,959. Descriptive and multivariate-adjusted models were fitted using Cox regression. A total of 1,032 (9.4%) participants were diagnosed with COVID-19 (879 students and 153 employees), almost 50% living with their families. COVID-19 was associated with living in college or residence (hazard ratio (HR) = 1.96, 95% CI: 1.45, 2.64), motor transportation (HR = 1.35, 95% CI: 1.14, 1.61), South American origin (HR = 1.43, 95% CI: 1.20, 1.72), and belonging to Madrid's campus (HR = 3.11, 95% CI: 2.47, 3.92). International students, especially from Latin America, mostly lived in university apartments or shared flats and cohabited with 4-11 people. Living in a big city (Madrid), was a significant risk factor.

Control of SARS-CoV-2 Infection Rates at a Spanish University With In-Person Class Attendance.

The "Safe Campus Program," implemented in 2020 through 2021 at the University of Navarra (Spain), aimed to guarantee a safe return to university campus and prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks, avoiding university-wide lockdown. It included COVID-19 education, campus adaptation, and polymerase chain reaction (PCR) testing. We describe the main characteristics of the program and analyze the SARS-CoV-2 cumulative incidence among 14 496 university members. The 14-day cumulative incidence in the university was 415.2 versus 447.7 in the region. The program, sustainable in the long term, achieved low SARS-CoV-2 in-campus rates.

Hospitalizations related to meningococcal infection in Spain from 1997 to 2018.

BACKGROUND: Baseline hospitalization, mortality, and in-hospital fatality rates for meningococcal infection are required to evaluate preventive interventions, such as the inclusion of the conjugated quadrivalent meningococcal vaccine and serogroup B based protein vaccines. METHODS: All meningococcal infection-related hospitalizations in any diagnostic position in Spain from 1st January 1997 through 31st December 2018 were analysed. The annual hospitalization rate, mortality rate and case-fatality rate were calculated. RESULTS: The average hospitalization rate for meningococcal infection was 1.64 (95% CI 1.61 to 1.66) hospitalizations per 100,000 inhabitants during the study period and significantly decreased from 1997 to 2018. Hospitalizations for meningococcal infection decreased significantly with age and were concentrated in children under 5 years of age (46%). The hospitalization rates reached 29 per 100,000 and 24 per 100,000 children under 1 and 2 years of age, respectively. The in-hospital case-fatality rate was 7.45% (95% CI 7.03 to 7.86). Thirty percent of the deaths occurred in children under 5 years of age, and more than half occurred in adults. The case fatality rate increased significantly with age (p < 0.001). CONCLUSION: It is necessary to maintain epidemiological surveillance of meningococcal infection to determine the main circulating serogroups involved, track their evolution, and evaluate preventive measures whose effectiveness must be assessed in all age groups.

Hospitalization burden and comorbidities of patients with rheumatoid arthritis in Spain during the period 2002-2017.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune rheumatic disease that is associated with multiple comorbidities and has a significant economic impact on the Spanish health system. The objective of this study was to estimate the rates of hospitalization of rheumatoid arthritis in Spain, and describing hospitalization rates and their changing by age, region, RA variant, and when RA as a main cause of hospitalization or a comorbidity. METHODS: Observational descriptive study that reviewed hospital records from the CMBD. We included all hospitalizations of patients in Spain whose main diagnosis or comorbidity in the ICD-9-CM was rheumatoid arthritis during the period of 2002-2017. RESULTS: A total of 315,190 hospitalizations with the RA code were recorded; 67.3% were in women. The mean age of the patients was 68.5 ± 13.9 years. The median length of hospital stay was 7 days (IQR 3-11 days). In 29,809 of the admissions, RA was coded as the main diagnosis (9.4%). When RA was not coded as the main diagnosis, the most frequent main diagnoses were diseases of the circulatory system (18.9%) and diseases of the respiratory system (17.4%). The hospitalization rate during the period of 2002-2017 was 43.8 (95% CI: 43.7-44.0) per 100,000 inhabitants and constantly increased during the period. The total cost for the healthcare system was 1.476 million euros, with a median of 3542 euros per hospitalization (IQR 2646-5222 euros). CONCLUSIONS: In Spain, the hospitalization rate of patients with RA increased during the study period, despite the decrease in the hospitalization rate when RA was the main diagnosis.

Evolving SARS-CoV-2 severity among hospital and university affiliates in Spain and Greater Boston.

INTRODUCTION: The COVID-19 pandemic caused by the SARS-CoV-2 virus greatly affected healthcare workers and healthcare systems. It also challenged schools and universities worldwide negatively affecting in-person education. We conducted this study is to assess the evolution of SARs-CoV-2 virulence over the course of the pandemic. METHODS: A combined cohort of University students in Spain and HCWs from the two hospitals in Spain, and one healthcare system in the Greater Boston area was followed prospectively from March 8th, 2020, to January 31st, 2022 for diagnosis with COVID-19 by PCR testing and related sequelae. Follow-up time was divided into four periods according to distinct waves of infection during the pandemic. Severity of COVID-19 was measured by case-hospitalization rate. Descriptive statistics and multivariable-adjusted statistics using the Poisson mixed-effects regression model were applied. As a sensitivity analysis, information on SARS-CoV-2 RNA in wastewater and COVID-19 deaths through May 30, 2023 from the Boston area was collected. RESULTS: For the last two periods of the study (January 1st to December 15th, 2021 and December 16th, 2021 to January 31st, 2022) and relative to the first period (March 8th to May 31st, 2020), the incidence rate ratios (IRRs) of hospitalization were 0.08 (95% CI, 0.03-0.17) and 0.03 (95% CI, 0.01-0.15), respectively. In addition, a relative risk 0.012 CI95% (0.012-0.012) was observed when comparing COVID-19 mortality versus SARS-CoV-2 RNA copies/mL in Boston-area wastewater over the period (16th December 2021 to 30th May 2023) and relative to the first period. CONCLUSIONS: The severity of COVID-19 and immunity of our populations evolved over time, resulting in a decrease in case severity. We found the case-hospitalization rate decreased more than 90% in our cohort despite an increase in incidence.

Safety of International Professional Sports Competitions During the COVID-19 Pandemic: The Association Football Experience.

Major sporting events were suspended during the most acute phase of the COVID-19 pandemic. Competitions are resuming with enhanced hygiene protocols and altered mechanics. While risks for players and staff have been studied, the impact of large-scale tournaments on the communities that host them remains largely unstudied. CONMEBOL Copa América is one of the first wide-scale international tournaments to be conducted in its original format since the beginning of the COVID-19 pandemic. The tournament saw 10 national teams compete in four Brazilian cities during a period of heightened viral transmission. The analysis of over 28,000 compulsory PCR tests showed that positive cases did not lead to the uncontrolled spread of the disease among staff and players. More importantly, the data indicate that locally hired staff were not exposed to increased risk while working. The Copa América experience shows that international sporting competitions can be conducted safely even under unfavourable epidemiological situations.

Association between COVID-19 and outstanding academic performance at a Spanish university.

BACKGROUND: SARS-CoV-2 is the causative agent of COVID-19 identified in December 2019, an acute infectious respiratory disease that can cause persistent neurological and musculoskeletal symptoms such as headache, fatigue, myalgias difficulty concentrating, among others including acute cerebrovascular disease with a prevalence of 1-35%. The aim of this study is to evaluate the impact of COVID-19 in undergraduate students on their academic performance as an indicator of their intellectual ability and performance in a university that maintained 100% face-to-face teaching during the 2020-2021 academic year. METHODS: A total of 7,039 undergraduate students were analyzed in a prospective cohort study at the University of Navarra. A questionnaire including sociodemographic and behavioral questions was sent. PCRs were performed throughout the academic year for the diagnosis of SARS-CoV-2 infection and students' academic results were provided by the academic center, adjusted descriptive and multivariate models were performed to assess the association. RESULTS: A total of 658 (9.3%) participants were diagnosed with COVID-19, almost 4.0% of them achieved outstanding academic results, while uninfected students did so in 7.3%. SARS-CoV-2 infection was associated with a significant decrease in having outstanding academic results (OR = 0.57; 95% CI: 0.38-0.86). CONCLUSION: Having COVID-19 disease, decreased academic performance in undergraduate students. Therefore, it is necessary to prevent infection even in the youngest sections of the population.

Functional social support: A systematic review and standardized comparison of different versions of the DUFSS questionnaire using the EMPRO tool.

BACKGROUND: Functional social support is one of the most established predictors of health, and the Duke-UNC Functional Social Support Questionnaire (DUFSS) is one of the most commonly used instruments to measure this parameter. The objective of this study is to systematically review the available evidence on the psychometric and administration characteristics of the different versions of the DUFSS and perform a standardized assessment though to a specifically designed tool. METHODS: A systematic review was performed in the PubMed/MEDLINE, SCOPUS, WOS and SCIELO databases. All articles that contained information on the development process of the instrument, the psychometric properties and aspects related to its administration were included, without restrictions based on publication date, language, or the version of the questionnaire that was studied. The selection and extraction procedure were carried out by two researchers. The articles finally included were peer-reviewed through a standardised assessment using the Evaluating the Measurement of Patient-Reported Outcomes (EMPRO) tool. PROSPERO registration number: CRD42022342977. RESULTS: A total of 54 articles were identified. After eliminating duplicates and screening articles based on the selection criteria, 15 studies that examined the DUFSS questionnaire resulting in 4 different versions: 3 articles obtained the 8-item version; 11 the 11-item version; and a single article obtained two versions, the 14-item version and the 5-item version. At least 60% of them did so in a young adult population, predominantly female and with a medium-low socio-economic level or with characteristics of social vulnerability. The EMPRO evaluation showed that the 11-item version (54.01 total score) was the only one that had been studied on all recommended attributes and had higher total scores than the other versions: 8 items (36.31 total score), 14 items (27.48 total score) and 5 items (23.81 total score). This difference appears in all attributes studied, with the highest scores in "reliability (internal consistency)" and "validity". CONCLUSIONS: Of the 4 versions identified in the DUFSS questionnaire, the 11-item version was found to be optimal based on the EMPRO standardized tool. Although, a priori, we could prioritise its use in epidemiological studies over the other versions, it should be noted that this version should also be used with caution because there are attributes that have not been studied.

Seroprevalence of SARS-CoV2 Infections in Health Care Personnel in a Long-Term Care Institution After the First Wave of the Pandemic: A Cross-Sectional Study.

BACKGROUND: At the time of our study, occupational health evidence specific for long-term care employees was mostly lacking. The purpose of this study was to determine the proportion of positive cases in employees after the first COVID-19 wave in May 2020. We also determined the prevalence of asymptomatic cases. METHOD: The study population included all health care workers (HCW) employed at one mid-size long-term hospital in Spain (May 2020). A cross-sectional study design included an interviewer-administered self-reported questionnaire (including sociodemographic questions, risk factors for COVID-19 complications such as hypertension or diabetes, and previous polymerase chain reaction [PCR] results) and antibody determination (Biozek rapid test). Data were analyzed using Student's t, Fisher, and chi-square tests. Two multivariate logistic models were created to evaluate exposure factors and symptoms separately on the outcome of having had COVID-19. FINDINGS: Of the 97% of workers who participated (580/596), 300 (51.7%) suffered symptoms of COVID-19, 161 (27.8%) of the rapid antibody tests were positive for IgM and/or IgG, 160 (27.6%) workers had at least one risk factor, and 32 (19.0%) of the 168 SARS-CoV-2-positive cases were asymptomatic. The proportion of negative or unavailable PCRs, with positive antibody, was 11.7% (56/477). Casual contact without protection (odds ratio [OR]: 1.9, 95% confidence interval [CI]: 1.1-3.4), doctor occupation (OR 3.3, 95% CI: 1.1-10.2), and nursing assistant occupation (OR 2.5, 95% CI: 1.2-5.8) were independently associated with SARS-CoV-2 infection. CONCLUSION: Physicians and nursing assistants in a long-term care setting were at a higher risk of SARS-COV-2 infection over other occupations in the first wave of the pandemic, especially when in contact with patients without protection. Almost one-fifth of the workers with a positive PCR test for SARS-COV-2 were asymptomatic and seroprevalence (27.8%) was well below the approximated herd immunity cutoff (60-70%). Essential workers in long-term care must be monitored frequently by Employee Health Service and should be required to wear personal protective equipment including a fit-tested N-95 while in close contact with patients and coworkers.

Effectiveness of a Conversational Chatbot (Dejal@bot) for the Adult Population to Quit Smoking: Pragmatic, Multicenter, Controlled, Randomized Clinical Trial in Primary Care.

BACKGROUND: Tobacco addiction is the leading cause of preventable morbidity and mortality worldwide, but only 1 in 20 cessation attempts is supervised by a health professional. The potential advantages of mobile health (mHealth) can circumvent this problem and facilitate tobacco cessation interventions for public health systems. Given its easy scalability to large populations and great potential, chatbots are a potentially useful complement to usual treatment. OBJECTIVE: This study aims to assess the effectiveness of an evidence-based intervention to quit smoking via a chatbot in smartphones compared with usual clinical practice in primary care. METHODS: This is a pragmatic, multicenter, controlled, and randomized clinical trial involving 34 primary health care centers within the Madrid Health Service (Spain). Smokers over the age of 18 years who attended on-site consultation and accepted help to quit tobacco were recruited by their doctor or nurse and randomly allocated to receive usual care (control group [CG]) or an evidence-based chatbot intervention (intervention group [IG]). The interventions in both arms were based on the 5A's (ie, Ask, Advise, Assess, Assist, and Arrange) in the US Clinical Practice Guideline, which combines behavioral and pharmacological treatments and is structured in several follow-up appointments. The primary outcome was continuous abstinence from smoking that was biochemically validated after 6 months by the collaborators. The outcome analysis was blinded to allocation of patients, although participants were unblinded to group assignment. An intention-to-treat analysis, using the baseline-observation-carried-forward approach for missing data, and logistic regression models with robust estimators were employed for assessing the primary outcomes. RESULTS: The trial was conducted between October 1, 2018, and March 31, 2019. The sample included 513 patients (242 in the IG and 271 in the CG), with an average age of 49.8 (SD 10.82) years and gender ratio of 59.3% (304/513) women and 40.7% (209/513) men. Of them, 232 patients (45.2%) completed the follow-up, 104/242 (42.9%) in the IG and 128/271 (47.2%) in the CG. In the intention-to-treat analysis, the biochemically validated abstinence rate at 6 months was higher in the IG (63/242, 26%) compared with that in the CG (51/271, 18.8%; odds ratio 1.52, 95% CI 1.00-2.31; P=.05). After adjusting for basal CO-oximetry and bupropion intake, no substantial changes were observed (odds ratio 1.52, 95% CI 0.99-2.33; P=.05; pseudo-R2=0.045). In the IG, 61.2% (148/242) of users accessed the chatbot, average chatbot-patient interaction time was 121 (95% CI 121.1-140.0) minutes, and average number of contacts was 45.56 (SD 36.32). CONCLUSIONS: A treatment including a chatbot for helping with tobacco cessation was more effective than usual clinical practice in primary care. However, this outcome was at the limit of statistical significance, and therefore these promising results must be interpreted with caution.

Effectiveness of the MULTIPAP Plus intervention in youngest-old patients with multimorbidity and polypharmacy aimed at improving prescribing practices in primary care: study protocol of a cluster randomized trial.

BACKGROUND: The progressive ageing of the population is leading to an increase in multimorbidity and polypharmacy, which in turn may increase the risk of hospitalization and mortality. The enhancement of care with information and communications technology (ICT) can facilitate the use of prescription evaluation tools and support system for decision-making (DSS) with the potential of optimizing the healthcare delivery process. OBJECTIVE: To assess the effectiveness and cost-effectiveness of the complex intervention MULTIPAP Plus, compared to usual care, in improving prescriptions for young-old patients (65-74 years old) with multimorbidity and polypharmacy in primary care. METHODS/DESIGN: This is a pragmatic cluster-randomized clinical trial with a follow-up of 18 months in health centres of the Spanish National Health System. Unit of randomization: family physician. Unit of analysis: patient. POPULATION: Patients aged 65-74 years with multimorbidity (≥ 3 chronic diseases) and polypharmacy (≥ 5 drugs) during the previous 3 months were included. SAMPLE SIZE: n = 1148 patients (574 per study arm). INTERVENTION: Complex intervention based on the ARIADNE principles with three components: (1) family physician (FP) training, (2) FP-patient interview, and (3) decision-making support system. OUTCOMES: The primary outcome is a composite endpoint of hospital admission or death during the observation period measured as a binary outcome, and the secondary outcomes are number of hospital admission, all-cause mortality, use of health services, quality of life (EQ-5D-5L), functionality (WHODAS), falls, hip fractures, prescriptions and adherence to treatment. Clinical and sociodemographic factors will be explanatory variables. STATISTICAL ANALYSIS: The main result is the difference in percentages in the final composite endpoint variable at 18 months, with its corresponding 95% CI. Adjustments by the main confounding and prognostic factors will be performed through a multilevel analysis. All analyses will be carried out in accordance to the intention-to-treat principle. DISCUSSION: It is important to prevent the cascade of negative health and health care impacts attributable to the multimorbidity-polypharmacy binomial. ICT-enhanced routine clinical practice could improve the prescription process in patient care. TRIAL REGISTRATION: ClinicalTrials.gov NCT04147130 . Registered on 22 October 2019.

Antibiotic prophylaxis adequacy assessment and its influence on surgical site infection in peripheral vascular bypass surgery.

OBJECTIVE: We sought to assess the degree of antibiotic prophylaxis adequacy to our surgical antibiotic prophylaxis protocol among patients who underwent peripheral vascular bypass surgery. MATERIALS AND METHODS: Prospective cohort study. Adequacy to protocol was studied by comparing the different aspects of prophylaxis received by patients to those stipulated in the protocol in force at our hospital. Incidence of surgical wound infection was calculated and the effect of prophylaxis inadequacy on the incidence of surgical wound infection was estimated using the relative risk. RESULTS: The study covered 266 patients. Incidence of surgical site infection (SSI) after the follow-up period was 5.3% (95% Confidence interval [CI]: 3.0-9.4). Overall adequacy to the protocol of antibiotic prophylaxis was 91.0% (95% CI: 87.6-94.4). The most frequent cause of inadequacy to the protocol was time of initiation of antibiotic prophylaxis (94.1%). No relationship was found between SSI and antibiotic prophylaxis inadequacy (relative risk: 2.4; 95% CI: 0.49-12.5; p > 0.05). CONCLUSIONS: Global adequacy to protocol of antibiotic prophylaxis was high. The most frequent cause of inadequacy to the protocol was time of initiation of antibiotic prophylaxis.

OBJETIVO: Buscamos evaluar el grado de adecuación de la profilaxis antibiótica a nuestro protocolo de profilaxis antibiótica quirúrgica entre los pacientes sometidos a cirugía de bypass vascular periférico. MATERIAL Y MÉTODOS: Estudio de cohortes prospectivo. La adecuación al protocolo se estudió comparando los diferentes aspectos de la profilaxis recibida por los pacientes con los estipulados en el protocolo vigente en nuestro hospital. Se calculó la incidencia de infección de herida quirúrgica y se estimó el efecto de la inadecuación de la profilaxis sobre la incidencia de infección de herida quirúrgica mediante el riesgo relativo. RESULTADOS: El estudio abarcó 266 pacientes. La incidencia de infección del sitio quirúrgico (ISQ) tras el periodo de seguimiento fue del 5,3% (intervalo de confianza [IC] del 95%: 3,0-9,4). La adecuación global al protocolo de profilaxis antibiótica fue del 91,0% (IC 95%: 87,6-94,4). La causa más frecuente de inadecuación al protocolo fue el momento de inicio de la profilaxis antibiótica (94,1%). No se encontró relación entre ISQ e inadecuación de la profilaxis antibiótica (riesgo relativo: 2,4; IC 95%: 0,49-12,5; p > 0,05). CONCLUSIONES: La adecuación global al protocolo de la profilaxis antibiótica fue alta. La causa más frecuente de inadecuación al protocolo fue el momento de inicio de la profilaxis antibiótica.

[Experience of a mid-term care facility in the covid-19 with visit protocols.] / Experiencia de un hospital de media estancia en época covid-19 con protocolos de visitas.

OBJECTIVE: The Hospital Virgen de la Poveda, (Villa del Prado, Spain), assists patients in need of Continuous medical care, Rehabilitation or Palliative care; these patients have many risk-factors of COVID-19 morbility and mortality. With both healthcare humanization and contagion-prevention purposes, in July 2020 two patient visit protocols were implemented. The objective of this study is to describe these measures qualitatively and quantitatively. METHODS: A context is provided regarding COVID-19 measures in this institution. The content and follow-up indicators of visit protocols (number of visits, of outbreaks, inpatients, etc.) and of their context were provided. The empirical outbreak probabilities were calculated, and hypothesis contrast was performed against no-visits (0%) and no visit-control (7-day cumulative incidence/habitant). RESULTS: Two protocols were created. Accompanying was applied to Palliative Care cases (no appointments required, no time limits), and a short visits protocol was applied to the other patients (appointments for 1 weekly visit for 1-2 persons were given and visits last up to 45 minutes). In both protocols, visitors with symptoms or fever or particularly susceptible were forbidden entrance. Between July and April 2021, 4,759 short-visit appointments were given and 7,544 total visits took place (short visits, accompanying, exceptions). An outbreak was possibly attributed to short visits (probability=0.021% [CI95%: 0.0005-0.1171%]) and two outbreaks were possibly attributed to visits globally (probability=0.0265% [IC95%: 0.0032-0.0958%]). CONCLUSIONS: Elaborating adapted, applicable and prospectively-evaluated protocols with prevention measures at multiple levels might succeed in minimizing the risk of adverse events (in this case, COVID-19 outbreaks).

OBJETIVO: El Hospital Virgen de la Poveda atiende a pacientes con necesidades de Cuidados Continuos, Rehabilitación o Cuidados Paliativos, que presentan factores de riesgo de morbilidad y mortalidad por COVID-19. Para humanizar la asistencia sanitaria, se implementaron en julio de 2020 protocolos de visitas que minimizasen el riesgo de contagio. El objetivo de este estudio fue realizar una descripción cualitativa y cuantitativa de tales medidas. METODOS: Se contextualizó el problema de las medidas ante el COVID-19 de esta institución. Se recogió el contenido e indicadores de seguimiento de los protocolos de visitas (número de visitas, de brotes, ocupación, etc.) y de contexto. Se calcularon probabilidades empíricas de brote y contraste de hipótesis: vs. no-visitas (0%), y vs. no-control (incidencia acumulada); (distribución de Poisson). RESULTADOS: Se crearon dos protocolos: acompañamiento (para Cuidados Paliativos, sin citas y sin límite a la duración); y visitas cortas con cita previa (para los demás, limitadas a 45 minutos, 1-2 personas por paciente, 1 visita semanal). En ambos casos se controlaron el acceso de personas con síntomas o especialmente susceptibles. Entre julio 2020 y abril de 2021 se dieron 4.759 citas para visitas cortas (con 1 posible brote atribuido, probabilidad de brote=0,021% [IC95%: 0,0005-0,1171%]) y se produjeron en total 7.544 visitas (citadas, acompañamiento y excepcionales; con 2 posibles brotes atribuidos, probabilidad de brote=0,0265% [IC95%: 0,0032-0,0958%]). CONCLUSIONES: La elaboración de protocolos con medidas de prevención a múltiples niveles, adaptados, aplicables y con un adecuado seguimiento, puede conseguir minimizar el riesgo de aparición de eventos negativos (brotes en este caso).

Surgical site infection in hip arthroplasty in a 10-year follow-up prospective study: Risk and factors associated.

BACKGROUND: The increased demand for hip arthroplasty means a growing number of postsurgical complications. This study aims to assess the risk of surgical site infection (SSI) in a teaching hospital; develop regional, national and international external comparisons; and evaluate SSI-related risk factors, particularly according to the timing of surgery (urgent/unplanned or elective). METHODS: Prospective cohort study from January 2008 to December 2018. Patients were followed up to 90 days after surgery. Primary endpoint was SSI incidence according to the Centers for Disease Control and Prevention criteria. Multivariate analysis was conducted to find independently associated SSI risk factors. The association between risk factors and SSI incidence was assessed by reference to odds ratio (OR). Analyses were also performed among urgent/unplanned and elective patients to identify whether SSI risk factors differed between groups. RESULTS: The study population (n = 1,808) has an overall SSI rate of 3.0% (95% confidence interval [CI]: 2.4-3.9). Timing of surgery caused an effect modification, so surgery duration> 75th percentile (OR: 3.8; 95% CI: 1.5-9.8) and inadequate preparation (OR: 3.3; 95% CI: 1.1-10.0) were independent risk factors in the urgent/unplanned group; National Healthcare Safety Network risk index≥ 2 (OR: 6.3; 95% CI: 0.1-19.2) and transfusion (OR: 3.6; 95% CI: 1.1-11.9) in the elective group. CONCLUSIONS: Hospital infection surveillance systems allow identifying risk factors susceptible to change. Characterization of factors that caused an effect modification is key to identify areas of quality improvement, including reducing operating times, preventing perioperative blood transfusion, or improving patient preparation before surgery.
