Palliative Care and the Self-Fulfilling Prophecy in Stroke Patients: is There Anything to Fear? A Retrospective Study of Patients Who Died During Hospitalization in a Quaternary Care Hospital.

BACKGROUND AND PURPOSE: Primary palliative care (PC) aims to improve the quality of life for patients with acute ischemic stroke but is often misinterpreted as withdrawal of care. The self-fulfilling prophecy withdrawal bias is feared in this context of PC's early implementation. This study evaluates stroke patients who died in the hospital to determine the impact of PC evaluation. METHODS: A retrospective descriptive analysis of patients who died from acute ischemic stroke was conducted. The study included patients aged ≥18 years admitted to the Stroke Unit of a quaternary hospital in Brazil from January 2017 to December 2018. The impact of PC assessment on outcomes was analyzed, with significance set at 5%. RESULTS: Among the patients who died during hospitalization as a result of an ischemic stroke (n = 77), 39 (%) were assessed by the palliative care team. There was no difference in the total length of stay or duration of antibiotic therapy. Logistic regression corrected for significant variables from the univariate analysis revealed that PC evaluation was associated with a 31-fold increase in opioid use (P < 0.001), a nearly 14-fold increase in discharges to the ward, and a threefold reduction in ICU length of stay (P = 0.011). CONCLUSION: PC team involvement was associated with higher rates of discharge to the floors, inferring more time spent with family and increased opioid use, suggesting better symptom control, without reducing the overall length of stay or duration of antibiotic therapy. This underscores that PC does not equate to withdrawal of care.

Epidemiological and Clinical Aspects of Cutaneous and Mucosal Leishmaniases in Portugal: Retrospective Analysis of Cases Diagnosed in Public Hospitals and Reported in the Literature between 2010 and 2020.

Leishmania infantum, a zoonotic vector-born parasite, is endemic in the Mediterranean region, presenting mostly as visceral (VL), but also as cutaneous (CL) and mucosal leishmaniasis (ML). This study aimed to describe the epidemiological and clinical aspects of the CL and ML cases diagnosed in mainland Portugal between 2010 and 2020. Collaboration was requested from every hospital of the Portuguese National Health System. Cases were screened through a search of diagnostic discharge codes or positive laboratory results for Leishmania infection. Simultaneously, a comprehensive literature search was performed. Descriptive statistics and hypothesis testing were performed using IBM® SPSS® Statistics. A total of 43 CL and 7 ML cases were identified, with a predominance of autochthonous cases (86%). In CL, immunosuppressed individuals constituted a significant proportion of patients (48%), and in this group, disseminated CL (22%) and simultaneous VL (54%) were common. In autochthonous cases, lesions, mostly papules/nodules (62%), were frequently observed on the head (48%). The approach to treatment was very heterogeneous. ML cases were all autochthonous, were diagnosed primarily in older immunosuppressed individuals, and were generally treated with liposomal amphotericin B. The findings suggest a need for enhanced surveillance and reporting, clinical awareness, and diagnostic capacity of these forms of leishmaniasis to mitigate underdiagnosis and improve patient outcomes. A holistic One Health approach is advocated to address the multifaceted challenges posed by leishmaniases in Portugal and beyond.

Serological screening in a large-scale municipal survey in Cascais, Portugal, during the first waves of the COVID-19 pandemic: lessons for future pandemic preparedness efforts.

Background: Serological surveys for SARS-CoV-2 were used early in the COVID-19 pandemic to assess epidemiological scenarios. In the municipality of Cascais (Portugal), serological testing combined with a comprehensive socio-demographic, clinical and behavioral questionnaire was offered to residents between May 2020 and beginning of 2021. In this study, we analyze the factors associated with adherence to this municipal initiative, as well as the sociodemographic profile and chronic diseases clinical correlates associated to seropositivity. We aim to contribute with relevant information for future pandemic preparedness efforts. Methods: This was a cross-sectional study with non-probabilistic sampling. Citizens residing in Cascais Municipality went voluntarily to blood collection centers to participate in the serological survey. The proportion of participants, stratified by socio-demographic variables, was compared to the census proportions to identify the groups with lower levels of adherence to the survey. Univariate and multivariate logistic regression were used to identify socio-demographic, clinical and behavioral factors associated with seropositivity. Results: From May 2020 to February 2021, 19,608 participants (9.2% of the residents of Cascais) were included in the study. Based on the comparison to census data, groups with lower adherence to this survey were men, the youngest and the oldest age groups, individuals with lower levels of education and unemployed/inactive. Significant predictors of a reactive (positive) serological test were younger age, being employed or a student, and living in larger households. Individuals with chronic diseases generally showed lower seroprevalence. Conclusion: The groups with low adherence to this voluntary study, as well as the socio-economic contexts identified as more at risk of viral transmission, may be targeted in future pandemic situations. We also found that the individuals with chronic diseases, perceiving higher risk of serious illness, adopted protective behaviors that limited infection rates, revealing that health education on preventive measures was effective for these patients.

Can the use of the CROS system provide head shadow effect contribution to unilateral Cochlear Implant Users?

PURPOSE: The aim of this study was to evaluate the contribution of the CROS system on the head shadow effect in unilateral implant users. METHODS: Prospective cross-sectional study, approved by the ethics committee under protocol 2.128.869. Eleven adults with post-lingual deafness users of unilateral Advanced Bionics CI were selected. Speech recognition was evaluated with recorded words presented at 65dBA at 0o azimuth and at 90o on the side contralateral to the CI, with noise at 55dBA, using CI alone and CI + CROS system. The results were analyzed using paired t-test with a 0.05 alpha. RESULTS: The mean speech recognition scores were significantly better with CI + CROS in relation to the condition of CI alone (p <0.05, p <0.005 and p <0.005 respectively). In the presentation at 0o azimuth, no significant differences were found. CONCLUSION: Users of unilateral CI without useful residual hearing for the use of hearing aids or unable to undergo bilateral surgery can benefit from the CROS device for speech recognition, especially when the speech is presented on the side contralateral to the CI.

NIH stroke scale and unfavourable outcomes in acute ischaemic stroke: retrospective study.

OBJECTIVES: To evaluate the determining factors of severe functional impairment (SFI) outcome at discharge and in-hospital mortality in patients who had an acute ischaemic stroke and thus favouring early implementation of primary palliative care (PC). METHODS: A retrospective descriptive study by the analysis of 515 patients who had an acute ischaemic stroke admitted at stroke unit, aged≥18 years, from January 2017 to December 2018. Previous clinical and functional status data, National Institute of Health Stroke Scale (NIHSS) on admission, and data related to the evolution during hospitalisation were evaluated, relating them to the SFI outcome at discharge and death. The significance level was set at 5%. RESULTS: Of 515 patients included, 15% (77) died, 23.3%(120) had an SFI outcome and 9.1% (47) were evaluated by the PC team. It was observed that NIHSS Score≥16 is responsible for a 15.5-fold increase in the occurrence of death outcome. The presence of atrial fibrillation was responsible for a 3.5-fold increase in the risk of this outcome. CONCLUSION: NIHSS Score is an independent predictor of in-hospital death and SFI outcomes at discharge. Knowledge about the prognosis and risk of developing unfavourable outcomes is important for planning the care of patients affected by a potentially fatal and limiting acute vascular insult.

Central Auditory Nervous System Stimulation through the Cochlear Implant Use and Its Behavioral Impacts: A Longitudinal Study of Case Series.

The purpose of this study was to investigate, over a period of five years, the cortical maturation of the central auditory pathways and its impacts on the auditory and oral language development of children with effective use and without effective use of a Cochlear Implant (CI). A case series study was conducted with seven children who were CI users and seven children with normal hearing, with age- and gender-matched to CI users. The assessment was performed by long-latency auditory evoked potentials and auditory and oral language behavioral protocols. The results pronounced P1 latency decrease in all CI users in the first nine months. Over five years, five children with effective CI use presented decrease or stabilization of P1 latency and a gradual development of auditory and oral language skills, although, for most of the children, the electrophysiological and behavior results remained poor than their hearing peers' results. Two children who stopped the effective use of CI after the first year of activation had worsened auditory and oral language behavioral skills and presented increased P1 latency. A negative correlation was observed between behavioral measures and the P1 latency, the P1 component being considered an important clinical resource capable of measuring the cortical maturation and the behavioral evolution.

Orbital Apex Syndrome due to Orbital Mucormycosis after Teeth Infection: A Successful Case Report.

Rhino-orbital-cerebral mucormycosis is a severe and rapidly progressive fungal infection associated with low survival rates. Early diagnosis and proper management are mandatory. We report the case of a 20-year-old female with diabetic ketoacidosis and teeth infection, who presented with sudden orbital apex syndrome. Several surgical procedures were necessary to provide a definite histopathological diagnosis of the fungal infection. Ultimately, given the progressive aggravation of the infection and the ineffectiveness of antifungal and antibiotic agents, an orbital exenteration was performed. A mycobacteriological examination revealed a polymicrobial culture with Mucorales. One year after the initial presentation, the patient is alive and with a good general health condition.

Aortic Prosthesis-Associated MDR Pseudomonas Infections as a Diagnostic and Therapeutic Challenge.

Endovascular prostheses are used to treat life-threatening conditions such as ruptured aortic aneurysms. Prosthetic infection cause significant morbidity and mortality, posing important diagnostic and therapeutic challenges. It is particularly difficult to diagnose and, in the era of multidrug resistance (MDR), these type of infections may become even more difficult to treat. Herein, we reported a case of a secondary prosthetic endovascular infection following repeated bacteremia episodes from a urinary source. This case illustrates an MDR Pseudomonas aeruginosa aortic infection that was difficult to diagnose with no oral antibiotic treatment options.

Azole-resistant Candida albicans Spondylodiscitis After Bariatric Surgery: A Case Report.

CASE: We present a case of azole and partial caspofungin-resistant Candida albicans spondylodiscitis, after bariatric surgery with bowel perforation. Treatment included debridement and several months of anidulafungin, complemented with antibacterial therapy because of relapse for bacterial superinfection. After treatment, the infection did not recur clinically or radiologically during one and half years follow-up. CONCLUSION: Although C. albicans spondylodiscitis is rare, fungi should be suspected as a causative agent. Adequate history, imaging and laboratory testing, and medical and surgical treatment should be performed to successfully eradicate the infection and resolve potential neurological deficits.

Sequential bilateral cochlear implant: results in children and adolescents / Implante coclear bilateral sequencial: resultados em crianças e adolescentes

Abstract Introduction: The use of the bilateral cochlear implants can promote the symmetrical development of the central auditory pathways, thus benefiting the development of auditory abilities and improving sound localization and the ability of auditory speech perception in situations of competitive noise. Objective: To evaluate the ability of speech perception in children and adolescents using sequential bilateral cochlear implants, considering the association of these variables: age at surgery, time of device use and interval between surgeries. Methods: A total of 14 individuals between 10 and 16 years of age, who demonstrated surgical indication for the use of sequential bilateral cochlear implants as intervention in the auditory habilitation process, were assessed. The speech perception ability was assessed through sentence lists constructed in the Portuguese language, presented in two situations: in silence, with fixed intensity of 60 dB SPL, and in competitive noise, with a signal-to-noise ratio of +15 dB. The evaluation was performed under the following conditions: unilateral with the first activated cochlear implant, unilateral with the second activated cochlear implant and bilateral with both devices activated. Results: The results of the speech perception tests showed better performance in both silence and in noise for the bilateral cochlear implant condition when compared to the 1st cochlear implant and the 2nd cochlear implant alone. A worse result of speech perception was found using the 2nd cochlear implant alone. No statistically significant correlation was found between age at the surgical procedure, interval between surgeries and the time of use of the 2nd cochlear implant, and the auditory speech perception performance for all assessed conditions. The use of a hearing aid prior to the 2nd cochlear implant resulted in benefits for auditory speech perception with the 2nd cochlear implant, both in silence and in noise. Conclusion: The bilateral cochlear implant provided better speech perception in silence and in noise situations when compared to the unilateral cochlear implant, regardless of the interval between surgeries, age at the surgical procedure and the time of use of the 2nd cochlear implant. Speech perception with the 1st cochlear implant was significantly better than with the 2nd cochlear implant, both in silence and in noise. The use of the hearing aid prior to the 2nd cochlear implant influenced speech perception performance with the 2nd cochlear implant, both in silence and in noise.

Resumo Introdução: A utilização do implante coclear bilateral pode promover o desenvolvimento das vias auditivas centrais de maneira simétrica, beneficiando, assim, o desenvolvimento das habilidades auditivas e melhorando a localização sonora e a habilidade de percepção auditiva da fala em situações de ruído competitivo. Objetivo: Avaliar a habilidade de reconhecimento de fala em crianças e adolescentes usuários do implante coclear bilateral sequencial, considerando a relação das variáveis: idade cirúrgica, tempo de uso do dispositivo e intervalo entre as cirurgias. Método: Foram avaliados 14 indivíduos entre 10 e 16 anos, que receberam indicação cirúrgica para implante coclear bilateral sequencial como forma de intervenção no processo de habilitação auditiva. A habilidade de reconhecimento de fala foi avaliada por meio de listas de sentenças construídas na língua portuguesa, apresentadas em duas situações: no silêncio, com intensidade fixa de 60 dB NPS, e no ruído competitivo, com a relação sinal/ruído de + 15 dB. A avaliação foi feita nas seguintes condições: unilateral com o 1° implante coclear ativado, unilateral com o 2° implante coclear ativado e bilateral com ambos os dispositivos ativados. Resultado: Os resultados dos testes de reconhecimento de fala demonstraram melhor desempenho tanto no silêncio quanto no ruído para a condição implante coclear bilateral, quando comparado ao 1° implante coclear e 2° implante coclear isoladamente. Um pior resultado de reconhecimento de fala foi encontrado com o uso do 2° implante coclear isoladamente. Não foi encontrada correlação estatisticamente significante entre idade cirúrgica, intervalo entre as cirurgias e tempo de uso do 2° implante coclear e o desempenho de percepção auditiva da fala para todas as condições avaliadas. O uso do aparelho de amplificação sonora individual anterior ao 2° implante coclear beneficiou os resultados de percepção auditiva da fala com o 2° implante coclear, tanto no silêncio quanto no ruído. Conclusão: O implante coclear bilateral proporcionou melhor reconhecimento de fala em situações de silêncio e de ruído, quando comparado com o implante coclear unilateral, independentemente do intervalo entre as cirurgias, da idade cirúrgica e do tempo de uso do 2° implante coclear. O reconhecimento de fala com o 1° implante coclear foi significativamente melhor do que com o 2° implante coclear, tanto no silêncio quanto no ruído. O uso do aparelho de amplificação sonora individual anterior ao 2° implante coclear influenciou o desempenho de reconhecimento de fala com o 2° implante coclear, tanto no silêncio quanto no ruído.

Influence of synthesis parameters on properties and characteristics of poly (urea-formaldehyde) microcapsules for self-healing applications.

Poly(urea-formaldehyde) (PUF) microcapsules filled with dicyclopentadiene (DCPD) were prepared by in situ polymerisation and the effect of synthesis parameters, such as pH of the solution and agitation rate, on microcapsules size and shell thickness was evaluated. Scanning electron microscopy (SEM) and Fourier transform infra-red spectroscopy (FTIR) were performed. Adjusted pH conditions (pH = 3.5) and agitation rate (1350 RPM) were found using a design of experiments (DOE). SEM results indicated that microcapsule size was directly affected by agitation rate, whereas shell thickness was mostly affected by pH. After obtaining adjusted synthesis conditions, microcapsules presenting mean size of 60 µm and mean shell thickness of 4 µm were embedded in an epoxy matrix for evaluating the self-healing effect. FTIR and SEM analyses in damaged samples suggested that a healing agent was delivered to the crack location.

Quality assessment of adult intensive care services: application of a tool adjusted to the reality of low-income countries. / Avaliação da qualidade de serviços de medicina intensiva adulto: aplicação de ferramenta ajustada à realidade de países de baixa renda.

OBJECTIVE: To assess the quality of adult intensive care units. METHODS: This population-based, cross-sectional, observational, analytical study evaluated management type in Maranhão, Brazil. An assessment instrument was applied that assigned scores to each service (maximum 124 points). The units were categorized as insufficient (< 50% of the maximum score), typical (≥ 50% and <80% of the maximum score), or sufficient (≥ 80% of the maximum score). RESULTS: Of the 26 intensive care units in Maranhão, 23 were evaluated; 15 (65.2%) were located in the state capital, and 14 (60.9%) were public. The mean final score was 67.2 (54.2% of the maximum). The worst performance was observed with regard to processes (50.9%) in the units located outside the capital (p = 0.037) and for hospitals with 68 beds or fewer (p = 0.027). The result of the assessment categorized services as a function of the overall total points earned. Specifically, 8 (34.8%) services were assessed as insufficient, 13 (56.5%) were assessed as typical, and 2 (8.7%) were assessed as sufficient. CONCLUSION: The majority of the intensive care units in this study were assessed as typical. These services must be better qualified. The priorities are the processes of the units located outside the capital and in small hospitals.

Chronic meningococcemia.

The spectrum of Neisseria meningitidis-associated clinical entities involves mild forms of disease, without neurological involvement or sepsis, and asymptomatic carrier states. Rarely, N. meningitidis bacteremia can be associated with a prolonged fever with or without arthritis, which we designate as chronic meningococcemia. Chronic meningococcemia is an uncommon entity, usually associated to serogroup B N. meningitidis. Diagnosis is frequently delayed as blood cultures collected outside febrile periods can be negative. We present a case of chronic meningococcemia in a 22-year-old woman with no relevant clinical background, presenting with fever, arthralgia and exanthem. Due to the potential for progression to more severe disease and the risk of N. meningitidis transmission and development of secondary cases, a high degree of clinical suspicion is required to ensure prompt recognition and adequate treatment. Our patient had a favorable outcome probably due to early recognition and adequate treatment, which is critical for the resolution of the disease without complications.

Quality of life and cochlear implant: results in adults with postlingual hearing loss / Qualidade de vida e implante coclear: resultados em adultos com deficiência auditiva pós-lingual

Abstract Introduction Considering the variability of results found in the clinical population using a cochlear implant, researchers in the area have been interested in the inclusion of quality of life measures to subjectively assess the benefits of the implantation. Objective To assess the quality of life of adult users of cochlear implant. Methods A cross-sectional and clinical study in a group of 26 adults of both genders, with mean duration of cochlear implant use of 6.6 years. The Nijmegen Cochlear Implantation Questionnaire and the generic World Health Organization Quality of Life questionnaire were sent electronically. Results The best assessed domain in the quality of life assessment for the cochlear implantation questionnaire was the social domain, whereas for the quality of life questionnaire it was the psychological domain. The variables, gender, time of cochlear implant use and auditory modality did not influence the results of both questionnaires. Only the variable level of education was correlated with the environment domain of the quality of life questionnaire. The variable telephone speech comprehension was associated with a better perception of quality of life for all the domains of the specific questionnaire and for the self-assessment of quality of life in general. Conclusion From the users' perspective, both questionnaires showed that cochlear implant brought benefits to different aspects related to quality of life.

Introdução: a orientação nutricional é de extrema importância para pacientes oncológicos, prevenindo deficiências nutricionais que podem gerar sérias complicações. Objetivo: avaliar o perfil nutricional de pacientes oncológicos. Método: estudo transversal, realizado em um centro de referência em oncologia de alfenas - MG. Para traçar o perfil nutricional de 52 pacientes oncológicos (n=52) durante o tratamento quimioterápico, foram utilizados métodos dietéticos e antropométricos (índice de massa corporal [iMc], prega cutânea tricipital [Pct], circunferência do braço [cB], circunferência muscular do braço [cMB] e percentagem da perda de peso [%PP]). dados gerais de saúde dos pacientes foram também avaliados. Resultados: Houve predominância do sexo feminino (63%), faixa etária >50 anos (40% ic95% 27-53,7). o tipo de câncer correlacionou-se ao sexo (p<0,01). no sexo feminino, o de mama teve prevalência de 51%, seguido pelo uterino (18%). no masculino, a prevalência de câncer de próstata foi de 10% e, comum aos dois sexos, o câncer de pulmão, de 15%, sendo o mais prevalente no masculino (32%). Hipertensão arterial sistêmica foi a comorbidade mais reportada (75%) e enjoos, o efeito adverso mais comum (69%). as médias dos parâmetros iMc, Pct, cB e cMB não sofreram alterações significativas (p>0,05) ao final do tratamento, mas 40% dos pacientes tiveram um grave %PP, 23% não grave %PP, 4% mantiveram o peso e 33% apresentaram ganho de peso. entre os pacientes avaliados, 48% usavam suplementos nutricionais. Conclusão: a orientação nutricional deve ser desenvolvida junto aos pacientes oncológicos, desde que se demonstrou um variado perfil nutricional em uma amostra heterogênea de pacientes

Introduction: nutritional counseling for patients with cancer is very important, because it can prevent nutritional deficiencies and other serious complications. Objective: to evaluate the nutritional profile of oncological patients. Method: cross-sectional study, carried out at a reference center in oncology, alfenas, Minas Gerais, Brazil. dietary and anthropometric methods (body mass index [BMi], triceps skinfold [ts], arm circumference [aB], arm muscle circumference [aMc], and percentage of weight loss [PWl]) were used to trace the nutritional profile of 52 oncological patients (n=52) during chemotherapy. other conditions of health were also evaluated. Results: There was a predominance of female sex (63%), and the age group >50 years (40% ci95[%] 27-53.7). The type of cancer correlated with patient's sex (p<0.01). in female sex, the breast cancer had a prevalence of 51%, followed by the uterus cancer (18%). in male sex, the prevalence of prostate cancer was 10%, and, common to both sexes, lung cancer had a prevalence of 15%, being the most prevalent in males (32%). systemic arterial hypertension was the most reported comorbidity (75%), and motion sickness the most common adverse event (69%). The mean values of the parameters BMi, ts, aB and aMc did not change significantly (p>0.05) at the end of the treatment, but 40% of the patients had a severe PWl, 23% no severe PWl, 4% kept the weight, and 33% presented weight gain. among the patients evaluated, 48% used nutritional supplements. Conclusion: nutritional counseling should be developed together with oncological patients, since we showed a variable nutritional profile in a heterogeneous sample of patients.

ntroducción: la orientación nutricional es de extrema importancia para los pacientes oncológicos, previniendo deficiencias nutricionales que pueden generar serias complicaciones. Objetivo: evaluar el perfil nutricional de 52 pacientes oncológicos. Método: estudio transversal, realizado en un centro de referencia en oncología de alfenas, Minas Gerais, Brasil. Para desenar el perfil nutricional de 52 pacientes oncológicos (n=52) durante la quimioterapia, se utilizaron métodos dietéticos y antropométricos (índice de masa corporal [iMc], pliegue cutáneo tricipital [Pct], circunferencia del brazo [cB], circunferencia muscular del brazo [cMB]) y el porcentaje de la pérdida de peso [% PP]). se evaluaron también los datos generales de salud de los pacientes. Resultados: Hubo predominancia del sexo femenino (63%), y la franja de edad >50 años (40% ic95% 27-53,7). el tipo de cáncer se correlacionó con el sexo (p<0,01). en el sexo femenino, el de mama tuvo prevalencia del 51%, seguido por el uterino (18%). Para el sexo masculino, la prevalencia de cáncer de próstata fue del 10% y, común a los dos sexos, el cáncer de pulmón tuvo una prevalencia del 15%, siendo el más prevalente el sexo masculino (32%). Hipertensión arterial sistémica fue la comorbilidad más reportada (75%), y mareo el efecto adverso más común (69%). los valores de los parámetros iMc, Pct, cB y cMB no sufrieron cambios significativos (p>0,05) al final del tratamiento, pero el 40% de los pacientes tuvieron una grave % PP, el 23% una no grave % PP, el 4% mantuvieron el peso y el 33% de los evaluados presentaron una ganancia de peso. entre los pacientes evaluados, 48% usaban suplementos nutricionales. Conclusión: la orientación nutricional debe desarrollarse junto a los pacientes oncológicos, una vez que se haya demostrado un variado perfil nutricional en una muestra heterogéneo de pacientes

Implementation and impact of an audit and feedback antimicrobial stewardship intervention in the orthopaedics department of a tertiary-care hospital: a controlled interrupted time series study.

A prospective audit and feedback antimicrobial stewardship intervention conducted in the Orthopaedics Department of a university hospital in Portugal was evaluated by comparing an interrupted time series in the intervention group with a non-intervention (control) group. Monthly antibiotic use (except cefazolin) was measured as the World Health Organization's Anatomical Therapeutic Chemical defined daily doses (ATC-DDD) from January 2012 to September 2016, excluding the 6-month phase of intervention implementation starting on 1 January 2015. Compared with the control group, the intervention group had a monthly decrease in the use of fluoroquinolones by 2.3 DDD/1000 patient-days [95% confidence interval (CI) -3.97 to -0.63]. An increase in the use of penicillins by 103.3 DDD/1000 patient-days (95% CI 47.42 to 159.10) was associated with intervention implementation, followed by a decrease during the intervention period (slope = -5.2, 95% CI -8.56 to -1.82). In the challenging scenario of treatment of osteoarticular and prosthetic joint infections, an audit and feedback intervention reduced antibiotic exposure and spectrum.
