Healthcare interactions prior to first hospital admission with alcohol-related liver disease.

BACKGROUND AND AIMS: To examine the healthcare contacts of patients in the year before an index admission to hospital with alcohol-related liver disease (ArLD) to identify where opportunities for earlier identification of alcohol use disorders (AUD) and ArLD and intervention may occur. METHODS: A retrospective cohort study using the regional database encompassing NHS organisations across North West London (344 general practitioner [GP] practices, 4 acute hospital trusts and 2 mental health and community health trusts). Patients who had an index admission with ArLD were identified through healthcare coding and compared with a control cohort. Healthcare contacts, blood tests and AUD testing in the year preceding admission were measured. RESULTS: The ArLD cohort had 1494 participants with an index hospital admission with ArLD. The control cohort included 4462 participants. In the year preceding an index admission with ArLD, 91% of participants had at least one contact with primary care with an average of 2.97 (SD 2.45) contacts; 80% (n = 1199/1494) attended ED, 68% attended an outpatient clinic, and 42% (n = 628/1494) had at least one inpatient admission. Only 9% of the ArLD (137/1494) had formal testing for AUD. Abnormal bilirubin and platelets were more common in the ArLD than the control cohort 25% (138/560) and 28% (231/837), respectively, v 1% (12/1228) and 1% (20/1784). CONCLUSIONS: Prior to an index admission with ArLD patients have numerous interactions with all healthcare settings, indicating missed opportunities for early identification and treatment.

Trauma Patient-Centered Discharge Plan Form: A Pilot Study.

BACKGROUND: Comprehensive and multidisciplinary discharge planning can improve trauma patient throughput, decrease length of hospitalization, increase family and patient support, and expedite hospital discharge. OBJECTIVE: This study aimed to assess the feasibility and acceptability of implementing a patient-centered discharge plan form for adult trauma patients. METHODS: A single-center pilot study was conducted with adult trauma patients on a neurosurgical medical-surgical floor at a Level II trauma center in the Western United States from January to February 2023. The study had three phases: observation, pilot intervention, and follow-up. The key pilot intervention was the development of a standardized patient-centered discharge plan form, pilot tested by a trauma advanced practice provider and an inpatient discharge nurse. The primary outcome was the frequency of discharge orders being written before noon on the day of discharge. Qualitative and quantitative outcomes are reported. RESULTS: The discharge form was used for eight patients during the pilot intervention phase; an advanced practice provider and an inpatient discharge nurse each completed the forms for four patients. Five of eight observed patients had discharge orders before noon; the incidence of orders before noon was slightly higher when the form was completed by the discharge nurse (three of four patients) than by the advanced practice provider (two of four patients). CONCLUSIONS: The pilot study found that the patient-centered discharge plan form was feasible and acceptable to help improve the discharge process for trauma patients. Additional work to further refine the form's content and administration is warranted.

Transplant Recipient Preferences Regarding Organ Donor Research: Their Role in Consent and use of Their Data.

Research on deceased organ donors has been hindered by concerns related to seeking research consent from transplant recipients. We undertook this qualitative study to elucidate solid organ transplant recipients views on organ donor research, their role in the consent for such research, and their preferences related to providing their data. We conducted interviews with 18 participants and three themes emerged from the data. The first centered around participant research literacy. The second described practical preferences of participating in research, and the third related to the connection between donor and recipient. We concluded that previously held views about the requirement for transplant recipients to have a consenting role in donor research is not always suitable.

Development of a consortium to examine organ donation legislative and system reforms: A report from the LEADDR consortium.

In April 2019, the province of Nova Scotia became the first jurisdiction in North America to pass legislation that incorporated deemed consent for deceased organ donation. The reform included many other important updates, including the hierarchy for consent, enabled donor and recipient contact, and mandatory referral of potential deceased donors. Additionally, system reforms were implemented to improve the deceased donation system in Nova Scotia. A collection of national colleagues identified the magnitude of the opportunity to develop a comprehensive strategy to measure and evaluate the impact of the legislative and system reforms. This article describes the successful development of a consortium from both national and provincial jurisdictions that included experts from a variety of backgrounds and clinical and administrative disciplines. In describing the creation of this group, we hope to offer our case example as a model for the evaluation of other health system reforms from a multidisciplinary perspective.

Evaluation of prototype risk prediction tools for clinicians and people living with type 2 diabetes in North West London using the think aloud method.

The prevalence of type 2 diabetes in North West London (NWL) is relatively high compared to other parts of the United Kingdom with outcomes suboptimal. This presents a need for more effective strategies to identify people living with type 2 diabetes who need additional support. An emerging subset of web-based interventions for diabetes self-management and population management has used artificial intelligence and machine learning models to stratify the risk of complications from diabetes and identify patients in need of immediate support. In this study, two prototype risk prediction tools on the MyWay Diabetes and MyWay Clinical platforms were evaluated with six clinicians and six people living with type 2 diabetes in NWL using the think aloud method. The results of the sessions with people living with type 2 diabetes showed that the concept of the tool was intuitive, however, more instruction on how to correctly use the risk prediction tool would be valuable. The feedback from the sessions with clinicians was that the data presented in the tool aligned with the key diabetes targets in NWL, and that this would be useful for identifying and inviting patients to the practice who are overdue for tests and at risk of complications. The findings of the evaluation have been used to support the development of the prototype risk predictions tools. This study demonstrates the value of conducting usability testing on web-based interventions designed to support the targeted management of type 2 diabetes in local communities.

Effect of perioperative benzodiazepine use on intraoperative awareness and postoperative delirium: a systematic review and meta-analysis of randomised controlled trials and observational studies.

BACKGROUND: Benzodiazepine use is associated with delirium, and guidelines recommend avoiding them in older and critically ill patients. Their perioperative use remains common because of perceived benefits. METHODS: We searched CENTRAL, MEDLINE, CINAHL, PsycInfo, and Web of Science from inception to June 2021. Pairs of reviewers identified randomised controlled trials and prospective observational studies comparing perioperative use of benzodiazepines with other agents or placebo in patients undergoing surgery. Two reviewers independently abstracted data, which we combined using a random-effects model. Our primary outcomes were delirium, intraoperative awareness, and mortality. RESULTS: We included 34 randomised controlled trials (n=4354) and nine observational studies (n=3309). Observational studies were considered separately. Perioperative benzodiazepines did not increase the risk of delirium (n=1352; risk ratio [RR] 1.43; 95% confidence interval [CI]: 0.9-2.27; I2=72%; P=0.13; very low-quality evidence). Use of benzodiazepines instead of dexmedetomidine did, however, increase the risk of delirium (five studies; n=429; RR 1.83; 95% CI: 1.24-2.72; I2=13%; P=0.002). Perioperative benzodiazepine use decreased the risk of intraoperative awareness (n=2245; RR 0.26; 95% CI: 0.12-0.58; I2=35%; P=0.001; very low-quality evidence). When considering non-events, perioperative benzodiazepine use increased the probability of not having intraoperative awareness (RR 1.07; 95% CI: 1.01-1.13; I2=98%; P=0.03; very low-quality evidence). Mortality was reported by one randomised controlled trial (n=800; RR 0.90; 95% CI: 0.20-3.1; P=0.80; very low quality). CONCLUSIONS: In this systematic review and meta-analysis, perioperative benzodiazepine use did not increase postoperative delirium and decreased intraoperative awareness. Previously observed relationships of benzodiazepine use with delirium could be explained by comparisons with dexmedetomidine. SYSTEMATIC REVIEW PROTOCOL: PROSPERO CRD42019128144.

A cross-sectional study evaluating the relationship between followership type and burnout amongst critical care followers.

INTRODUCTION: Healthcare teams include both leaders and followers, with followers making up the majority of the healthcare team. There are five followership styles which have been described by Kelly (1992) based on critical thinking and active engagement. We aim to explore if a relationship exists between followership style and burnout, and also with job satisfaction of followers within the critical care setting. Additionally, we aim to quantify the distribution of followership types amongst followers within the critical care setting. METHODS: Participants were recruited in person at random to participate in a single centered, cross sectional, four-part survey to determine their followership type (Kelly followership type), burnout (Maslach Burnout Inventory) and job satisfaction (Brayfiled-Rothe Survey and Work and Meaning Inventory). Correlations between followership type and burnout as well as followership type and job satisfaction were then determined. RESULTS: A total of 64 participants (27 residents and 37 critical care nurses) took part in the study. There was a weak-moderate correlation between independent critical thinking and personal accomplishment (R = 0.297), and moderate correlation to meaningful work (R = 0.390), and job satisfaction (R = -0.300). Active engagement was moderately correlated with personal accomplishment (R = 0.302), meaningful work (R = 0.448) and job satisfaction (R = -0.418). Neither independent critical thinking nor active engagement showed significant correlation with depersonalization and emotional exhaustion subscales. Most participants were characterized into effective/exemplary followership type with no statistically significant differences between nurses and residents. CONCLUSION: This research shows that by creating an environment which promotes critical thinking and active engagement, nurses and residents may display less burnout, and enhanced job satisfaction.

Association of primary and community care services with emergency visits and hospital admissions at the end of life in people with cancer: a retrospective cohort study.

OBJECTIVE: To examine the association between primary and community care use and measures of acute hospital use in people with cancer at the end of life. DESIGN: Retrospective cohort study. SETTING: We used Discover, a linked administrative and clinical data set from general practices, community and hospital records in North West London (UK). PARTICIPANTS: People registered in general practices, with a diagnosis of cancer who died between 2016 and 2019. PRIMARY AND SECONDARY OUTCOME MEASURES: ≥3 hospital admissions during the last 90 days, ≥1 admissions in the last 30 days and ≥1 emergency department (ED) visit in the last 2 weeks of life. RESULTS: Of 3581 people, 490 (13.7%) had ≥3 admissions in last 90 days, 1640 (45.8%) had ≥1 admission in the last 30 days, 1042 (28.6%) had ≥1 ED visits in the last 2 weeks; 1069 (29.9%) had more than one of these indicators. Contacts with community nurses in the last 3 months (≥13 vs <4) were associated with fewer admissions in the last 30 days (risk ratio (RR) 0.88, 95% CI 0.90 to 0.98) and ED visits in the last 2 weeks of life (RR 0.79, 95% CI 0.68 to 0.92). Contacts with general practitioners in the last 3 months (≥11 vs <4) was associated with higher risk of ≥3 admissions in the last 90 days (RR 1.63, 95% CI 1.33 to 1.99) and ED visits in the last 2 weeks of life (RR 1.27, 95% CI 1.10 to 1.47). CONCLUSIONS: Expanding community nursing could reduce acute hospital use at the end of life and improve quality of care.

Burden and impact of chronic cough in UK primary care: a dataset analysis.

OBJECTIVE: Chronic cough (CC) is a debilitating respiratory symptom, now increasingly recognised as a discrete disease entity. This study evaluated the burden of CC in a primary care setting. DESIGN: Cross-sectional, retrospective cohort study. SETTING: Discover dataset from North West London, which links coded data from primary and secondary care. The index date depicted CC persisting for ≥8 weeks and was taken as a surrogate for date of CC diagnosis. PARTICIPANTS: Data were extracted for individuals aged ≥18 years with a cough persisting ≥8 weeks or cough remedy prescription, between Jan 2015 and Sep 2019. MAIN OUTCOME MEASURES: Demographic characteristics, comorbidities and service utilisation cost, including investigations performed and treatments prescribed were determined. RESULTS: CC was identified in 43 453 patients from a total cohort of 2 109 430 (2%). Median (IQR) age was 64 years (41-87). Among the cohort, 31% had no recorded comorbidities, 26% had been given a diagnosis of asthma, 17% chronic obstructive pulmonary disease, 12% rhinitis and 15% reflux. Prevalence of CC was greater in women (57%) and highest in the 65-74 year age range. There was an increase in the number of all investigations performed in the 12 months before and after the index date of CC diagnosis, and in particular for primary care chest X-ray and spirometry which increased from 6535 to 12 880 and from 5791 to 8720, respectively. This was accompanied by an increase in CC-associated healthcare utilisation costs. CONCLUSION: One-third of individuals had CC in the absence of associated comorbidities, highlighting the importance of recognising CC as a condition in its own right. Overall outpatient costs increased in the year after the CC index date for all comorbidities, but varied significantly with age. Linked primary-care datasets may enable earlier detection of individuals with CC for specialist clinic referral and targeted treatment.

Palliative Integration Into Ambulatory Oncology: An Advance Care Planning Quality Improvement Project.

Advance care planning (ACP) is essential to ensuring that patient-centered end-of-life goals are respected if a health crisis occurs. Advanced practitioner barriers to ACP include insufficient time and limited confidence in discussions. The purpose of this quality improvement project was to increase advanced cancer patients' electronic health record (EHR) documented surrogate decision maker and ACP documentation by 25% over 8 weeks. A secondary aim was to decrease patients' decisional conflict scores (DCS) related to life-sustaining treatment preferences after a clinical nurse specialist (CNS)-led ACP session. Using the define, measure, analyze, improve, and control (DMAIC) process of quality improvement methodology, an interprofessional team led by a palliative CNS fostered practice change by (a) incorporating a patient self-administered Supportive Care and Communication Questionnaire (SCCQ) to standardize the ACP assessment, (b) creating an EHR nursing and provider documentation template, (c) offering advanced cancer patients a palliative CNS consultation for ACP review and advance directive completion, and (d) evaluating patients' DCS through the four-item SURE tool. Of 126 participants provided with the SCCQ, 90 completed the document, resulting in a 71% return rate. Among the completed SCCQs, 37% (n = 33) requested a CNS consultation, with 76% (n = 25) returning for the ACP session. The CNS intervention yielded an average reduction of 1.4 points in SURE tool findings, a statistically significant decrease determined by a paired sample t-test. The project's interprofessional collaboration promoted a system-wide standardized ACP process throughout ambulatory, acute, and post-hospital settings.

Identification of palliative care needs among people with dementia and its association with acute hospital care and community service use at the end-of-life: A retrospective cohort study using linked primary, community and secondary care data.

BACKGROUND: Hospital admissions among people dying with dementia are common. It is not known whether identification of palliative care needs could help prevent unnecessary admissions. AIM: To examine the proportion of people with dementia identified as having palliative care needs in their last year of life, and the association between identification of needs and primary, community and hospital services in the last 90 days. DESIGN: Retrospective cohort study using Discover, an administrative and clinical dataset from 365 primary care practices in London with deterministic individual-level data linkage to community and hospital records. SETTING/PARTICIPANTS: People diagnosed with dementia and registered with a general practitioner in North West London (UK) who died between 2016 and 2019. The primary outcome was multiple non-elective hospital admissions in the last 90 days of life. Secondary outcomes included contacts with primary and community care providers. We examined the association between identification of palliative care needs with outcomes. RESULTS: Among 5804 decedents with dementia, 1953 (33.6%) were identified as having palliative care needs, including 1141 (19.7%) identified before the last 90 days of life. Identification of palliative care needs before the last 90 days was associated with a lower risk of multiple hospital admissions (Relative Risk 0.70, 95% CI 0.58-0.85) and more contacts with the primary care practice, community nurses and palliative care teams in the last 90 days. CONCLUSIONS: Further investigation of the mechanisms underlying the association between identification of palliative care needs and reduced hospital admissions could help reduce reliance on acute care for this population.

A Program of Research to Evaluate the Impact of Deceased Organ Donation Legislative Reform in Nova Scotia: The LEADDR Program.

BACKGROUND: This is the first time deemed consent, where the entire population of a jurisdiction is considered to have consented for donation unless they have registered otherwise, will be implemented in North America. While relatively common in other regions of the world-notably Western Europe-it is uncertain how this practice will influence deceased donation practices and attitudes in Canada. METHODS: We describe a Health Canada funded program of research that will evaluate the implementation process and full impact of the deceased organ donation legislation and the health system transformation in Nova Scotia that includes opt-out consent. RESULTS: There is a need to evaluate the impact of these changes to inform not only Nova Scotia and Atlantic Canada, but also other provincial, national, and international stakeholders. CONCLUSIONS: We establish a rigorous academic framework that we will use to evaluate this significant health system transformation.

The value of teaching increases with tool complexity in cumulative cultural evolution.

Human cumulative cultural evolution (CCE) is recognized as a powerful ecological and evolutionary force, but its origins are poorly understood. The long-standing view that CCE requires specialized social learning processes such as teaching has recently come under question, and cannot explain why such processes evolved in the first place. An alternative, but largely untested, hypothesis is that these processes gradually coevolved with an increasing reliance on complex tools. To address this, we used large-scale transmission chain experiments (624 participants), to examine the role of different learning processes in generating cumulative improvements in two tool types of differing complexity. Both tool types increased in efficacy across experimental generations, but teaching only provided an advantage for the more complex tools. Moreover, while the simple tools tended to converge on a common design, the more complex tools maintained a diversity of designs. These findings indicate that the emergence of cumulative culture is not strictly dependent on, but may generate selection for, teaching. As reliance on increasingly complex tools grew, so too would selection for teaching, facilitating the increasingly open-ended evolution of cultural artefacts.

Blood tests in general practice: the use of routine data to characterise venous blood testing in North West London, 2016-2018.

BACKGROUND: Laboratory testing is an integral diagnostic tool, contributing to 70% of diagnoses in the NHS today. Its use has been steadily increasing despite estimates that ≤40% of blood tests ordered are unnecessary. Understanding blood-testing patterns is a fundamental step to tackling overuse. AIM: To characterise the volume, type, and per patient frequency (PPF) of venous blood testing reported in general practice in North West London, 2016-2018. METHOD: Following ethics clearance, aggregate data of blood tests reported in general practice in North West London between 2016 and 2018 were extracted from the Discover database. Non-venous blood test codes and codes not used within the designated time period were excluded. Codes reporting the same analyte were aggregated. Overall volume and PPF were calculated per analyte. RESULTS: Three hundred and thirty-six individual analytes were reported and grouped into 35 recognised panels or groupings. Blood testing increased by 16.5% over the 3-year period. Full blood count, urea and electrolytes, liver function tests, and lipid profile accounted for 80.4% of all venous blood tests. Requests for HbA1c increased by 52.8% and non-HDL cholesterol by 148.7%, whereas glucose decreased by 13.3% and urea by 15.7%. The PPF remained unchanged over the 3-year period at 1.29 blood tests per person per year. The coagulation assay had the highest PPF at 3.0. CONCLUSION: Routine general practice data revealed important trends in blood testing. Trends uncovered can inform innovative and targeted solutions to reduce unnecessary blood testing.

Teaching Crisis Resource Management Skills to Nurses Using Simulation.

BACKGROUND: Education programs teaching crisis resource management (CRM) skills (problem solving, situational awareness, resource utilization, communication, and leadership) have been shown to positively affect learner competence in handling crisis events. As part of an education program, a high-fidelity simulation program was used as a learning intervention to teach these skills to practicing nurses. METHOD: In this repeated-measures observational study, 11 RNs were evaluated at four time points, measuring the effect of an education program on observed performance of CRM skills. Performance was measured using the Ottawa Global Rating Scale and a checklist tool. RESULTS: Statistically significant changes in mean scores occurred between times one and two, and nonstatistically significant improvement occurred in means overall. CONCLUSION: This study adds evidence of the effectiveness of high-fidelity simulation education and highlights the need for further research. [J Contin Educ Nurs. 2020;51(6):257-266.].

How an electronic health record became a real-world research resource: comparison between London's Whole Systems Integrated Care database and the Clinical Practice Research Datalink.

BACKGROUND: In the UK, several initiatives have resulted in the creation of local data warehouses of electronic patient records. Originally developed for commissioning and direct patient care, they are potentially useful for research, but little is known about them outside their home area. We describe one such local warehouse, the Whole Systems Integrated Care (WSIC) database in NW London, and its potential for research as the "Discover" platform. We compare Discover with the Clinical Practice Research Datalink (CPRD), a popular UK research database also based on linked primary care records. METHODS: We describe the key features of the Discover database, including scope, architecture and governance; descriptive analyses compare the population demographics and chronic disease prevalences with those in CPRD. RESULTS: As of June 2019, Discover held records for a total of 2.3 million currently registered patients, or 95% of the NW London population; CPRD held records for over 11 million. The Discover population matches the overall age-sex distribution of the UK and CPRD but is more ethnically diverse. Most Discover chronic disease prevalences were comparable to the national rates. Unlike CPRD, Discover has identifiable care organisations and postcodes, allowing mapping and linkage to healthcare provider variables such as staffing, and includes contacts with social, community and mental health care. Discover also includes a consent-to-contact register of over 3000 volunteers to date for prospective studies. CONCLUSIONS: Like CPRD, Discover has been a number of years in the making, is a valuable research tool, and can serve as a model for other areas developing similar data warehouses.

Research Consent Models Used in Prospective Studies of Neurologically Deceased Organ Donors: A Systematic Review.

Research to inform the care of neurologically deceased organ donors is complicated by a lack of standards for research consent. In this systematic review, we aim to describe current practices of soliciting consent for participation in prospective studies of neurologically deceased donors, including the frequency and justification for these various models of consent. Among the 74 studies included, 14 did not report on any regulatory review, and 13 did not report on the study consent procedures. Of the remaining 47 studies, 24 utilized a waiver of research consent. The most common justification for a waiver of research consent related to the fact that neurologically deceased donors are not considered human subjects. In conclusion, among studies of neurologically deceased donors, research consent models vary and are inconsistently reported. Consensus and standardization in the application of research consent models will help to advance this emerging field of research.

Evaluating a digital tool for supporting breast cancer patients: a randomized controlled trial protocol (ADAPT).

BACKGROUND: There are a growing number of mHealth tools for breast cancer patients but a lack of scientific evidence for their effects. Recent studies have shown a mix of positive and negative impacts on users. Here we will assess the impact of OWise Breast Cancer, a mobile application for self-monitoring symptoms and managing care, on the process of self-management. METHODS: This randomized controlled trial with early stage breast cancer patients will assess the effect of OWise use on patient activation at 3 months from diagnosis measured by the PAM-13 questionnaire. We will also assess differences in changes in health-related quality of life, psychological distress, health status, and National Health Service (NHS) health resource utilization over the first year from diagnosis. Participants will be randomly allocated (1:1) to standard care or standard care plus OWise. Participants will complete questionnaires before starting anti-cancer treatment and at 3, 6, and 12 months from diagnosis. Clinical and patient-reported outcome data will be linked to health resource utilization data from Discover, an integrated care record of primary, secondary, and social care in North West London. We will measure contamination in the control group and adjust the sample size to mitigate the dilution of effect estimates. A per-protocol analysis will be conducted as a sensitivity analysis to assess robustness of the primary results. DISCUSSION: This study aims to generate evidence for the effectiveness of OWise at improving patient activation for women with early-stage breast cancer. The results will show the impact of using the tool at the patient level and the NHS health system level. The outcomes of the study will have implications for the application of OWise across the NHS for breast cancer patients and expansion into other tumor types. Assessing publicly available mHealth tools poses a challenge to trialists due to the risk of contamination. Here we apply various methods to measure, mitigate, and assess the effects of contamination. TRIAL REGISTRATION: The study was registered at clincaltrials.gov (NCT03866655) on 7 March 2019.

Detecção de beta-lactamase por Staphylococcus coagulase-negativo isolados de queijo mussarela fatiados e fatiadores de frios / Beta-lactamase detection in coagulase-negative Staphylococci isolated from sliced mozzarella cheese and cold-cut slicers

A resistência de bactérias a antimicrobianos é considerada um problema de saúde pública, sendo a resistência aos beta-lactâmicos uma das mais importantes. O objetivo do presente estudo foi detectar a produção da enzima β-lactamase por isolados de Staphylococcus coagulase-negativo (SCN), provenientes de queijos Mussarela fatiados e equipamentos de fatiamento de frios. Os testes foram realizados utilizando discos impregnados com cefalosporina cromógena para detecção da β-lactamase. Dos 103 isolados de Staphylococcus spp. analisados, 55 (53%) produziram β-lactamase e 48 (47%) não produziram. Portanto, é possível inferir que SCN isolados neste estudo, podem inativar antimicrobianos β-lactâmicos e assim, exercer influência negativa na saúde pública, devido ao potencial em transferir genes de resistência antimicrobiana para outras bactérias.

Produção de biofilme por Staphylococcus coagulase negativa isolados de queijos e equipamentos / Biofilm production by coagulase-negative Staphylococci isolated from cheese and equipments

Biofilme é uma comunidade organizada de microrganismos que se forma em superfícies mal higienizadas, constituindo um mecanismo de defesa microbiana para permanência no ambiente. O objetivo do presente estudo foi investigar a capacidade de formação de biofilme de espécies de Staphylococcus coagulase negativa (SCN) isoladas de queijo Mussarela fatiado e de fatiadores de frios de estabelecimentos do município de Garanhuns-PE. De 103 isolados de SCN 56 (54,4%) foram negativos para produção de biofilme e 47 (45,6%) positivos, com a maior frequência de detecção nas espécies S. saprophyticus e S. cohnii subsp. urealyticum. Os resultados apontam para o potencial risco de contaminação cruzada de outros alimentos, uma vez que cepas bacterianas produtoras de biofilmes podem colonizar e persistir em superfícies de diversos equipamentos.
