Gestión de camas hospitalarias durantela pandemia en Navarra con el apoyo demétodos matemáticos de predicción / Management of hospital beds during the pandemic in Navarra with the support of mathematical prediction methods

Durante la pandemia por coronavirus, en Navarra se utilizaron modelos matemáticos depredicción para estimar las camas necesarias, convencionales y de críticos, para atender alos pacientes COVID-19. Las seis ondas pandémicas presentaron distinta incidencia en la población, ocasionandovariabilidad en los ingresos hospitalarios y en la ocupación hospitalaria. La respuesta a laenfermedad de los pacientes no fue constante en cada onda, por lo que, para la predicción decada una, se utilizaron los datos correspondientes de esa onda.El método de predicción constó de dos partes: una describió la entrada de pacientes alhospital y la otra su estancia dentro del mismo. El modelo requirió de la alimentación a tiempo real de los datos actualizados. Los resultados delos modelos de predicción fueron posteriormente volcados al sistema de información corporativotipo Business Intelligence. Esta información fue utilizada para planificar el recurso cama y lasnecesidades de profesionales asociadas a la atención de estos pacientes en el ámbito hospitalario.En la cuarta onda se realizó un análisis para cuantificar el grado de acierto de los modelospredictivos. Los modelos predijeron adecuadamente el pico, la meseta y el cambio detendencia, pero sobreestimaron los recursos necesarios para la atención de los pacientes enla parte descendente de la curva. El principal punto fuerte de la sistemática utilizada para la construcción de modelospredictivos fue proporcionar modelos en tiempo real con datos recogidos con precisión porlos sistemas de información que consiguieron un grado de acierto aceptable permitiendo unautilización inmediata.(AU)

Do Patients and Relatives Have Different Dispositions When Challenging Healthcare Professionals About Patient Safety? Results Before and After an Educational Program.

BACKGROUND: There is a universal interest in evaluating the new roles of patients to improve patient safety. However, relatively little is known about the contribution of family caregivers. The purposes of this study was to determine whether patients and relatives (P&Rs) have different dispositions when challenging healthcare professionals about patient safety and to measure the influence of an educational program. METHODS: An interventional before-and-after design was used to determine the P&Rs' basal level of willingness and the influence of a training program. One hundred thirty-six participants were recruited, 90 patients and 46 relatives, from the Day Hospital of a Tertiary Hospital in Spain, in 2018.The safe practices selected were as follows: patient identification, hand hygiene, blood or chemotherapy identification, and secondary effects of treatment. The educational materials comprised brochures and story-type videos. A questionnaire measured participants' willingness to speak up before and after the training. RESULTS: One hundred thirty-six P&Rs (63% response rate) agreed to participate. The hypothesis that relatives are more willing to challenge healthcare professionals could not be proven. Their willingness to speak up depended on the type of safe practice both before and after training, ranging from 42% to 87%. The percentage of items that P&Rs were willing to challenge increased after the training among both the patients and the relatives, but statically significant differences were only seen among patients. CONCLUSIONS: After the training, participants' willingness to challenge healthcare workers was high for all safe practices analyzed but hand hygiene. Patients and relatives had very similar willingness. After the training, participants felt confident with their knowledge about safe practices, thereby increasing their challenging attitude.

Patients and relatives as auditors of safe practices in oncology and hematology day hospitals.

BACKGROUND: When there is a gap in professionals' adherence to safe practices during cancer treatment, the consequences can be serious. Identifying these gaps in order to enable improvements in patient safety can be a challenge. This study aimed to assess if cancer patients and their relatives can be given the skills to audit reliably four safe practices, and to explore whether they are willing to play this new role. METHODS: We recruited 136 participants in 2018, from the oncology and haematology day hospital of a tertiary hospital in Spain. Patient identification, hand hygiene, blood or chemotherapy identification, and side effects related to transfusion and chemotherapy, were the safe practices selected for evaluation. The study comprised two parts: an interventional educational program and a cross-sectional design to collect data and assess to what degree participants are able and willing to be auditors depending on their characteristics using multivariate logistic regression models. A participant's auditing skill were assessed pre and post the educational intervention. RESULTS: The model was seeking predictors of being a good auditor. 63 participants (46.3%) were classified as good auditors after the training. To have younger age, higher educational level and to have had an experience of an adverse event were associated with a higher probability of being a good auditor. Additionally, 106 (77.9%) participants said that they would like to audit anonymously the professionals' compliance of at least three of four safe practices. The willingness to audit safe practices differed depending on the safe practice but these differences did not reach statistical significance. CONCLUSIONS: The data gathered by patients and relatives acting as auditors can provide healthcare organizations with valuable information about safety and quality of care that is not accessible otherwise. This new role provides an innovative way to engage patients and their families' in healthcare safety where other methods have not had success. The paper sets out the methods that healthcare organizations need to undertake to enrol and train patients and relatives in an auditor role.

Self-Collection of Saliva Specimens as a Suitable Alternative to Nasopharyngeal Swabs for the Diagnosis of SARS-CoV-2 by RT-qPCR.

A nasopharyngeal swab is a sample used for the diagnosis of SARS-CoV-2 infection. Saliva is a sample easier to obtain and the risk of contagion for the professional is lower. This study aimed to evaluate the utility of saliva for the diagnosis of SARS-CoV-2 infection. This prospective study involved 674 patients with suspected SARS-CoV-2 infection. Paired nasopharyngeal and saliva samples were processed by RT-qPCR. Sensitivity, specificity, and kappa coefficient were used to evaluate the results from both samples. We considered the influence of age, symptoms, chronic conditions, and sample processing with lysis buffer. Of the 674 patients, 636 (94.4%) had valid results from both samples. The virus detection in saliva compared to a nasopharyngeal sample (gold standard) was 51.9% (95% CI: 46.3%-57.4%) and increased to 91.6% (95% CI: 86.7%-96.5%) when the cycle threshold (Ct) was ≤ 30. The specificity of the saliva sample was 99.1% (95% CI: 97.0%-99.8%). The concordance between samples was 75% (κ = 0.50; 95% CI: 0.45-0.56). The Ct values were significantly higher in saliva. In conclusion, saliva sample utility is limited for clinical diagnosis, but could be a useful alternative for the detection of SARS-CoV-2 in massive screening studies, when the availability of trained professionals for sampling or personal protection equipment is limited.

Validez de las bases de datos administrativas para realizar ajustes de riesgo en el análisis de los efectos adversos producidos en pacientes quirúrgicos / Usefulness of administrative databases for risk adjustment of adverse events in surgical patients

OBJETIVO: Conocer la validez de las bases de datos clínico-administrativas para realizar ajustes de riesgo en el estudio de los efectos adversos que pueden sufrir los pacientes intervenidos quirúrgicamente. MÉTODOS: Se estudiaron 1.602 episodios de hospitalización de pacientes intervenidos quirúrgicamente durante los años 2008 y 2010 en un hospital terciario situado en el norte de España. Se analizaron 40 variables de comorbilidades que recoge el Colegio Americano de Cirujanos en el National Surgical Quality Improvement Program (NSQIP) a través de 2 fuentes de información: el conjunto mínimo básico de datos (CMBD) y los datos extraídos de la historia clínica completa (HC), considerada como patrón oro. Se catalogaron las variables en función de que los valores de sensibilidad (S), valor predictivo positivo (VPP) y kappa (K) fueran superiores a 0,6. RESULTADOS: La media de comorbilidades por paciente fue de 1,6 mediante la HC y de 0,95 a través del CMBD (p < 0,0001). El CMBD no detectó ningún caso en 13 comorbilidades (estas supusieron el 8% de las comorbilidades detectadas con la HC). De las 27 comorbilidades restantes, 5 cumplieron los 3 criterios establecidos (S, VPP y k > 0,6), 2 enfermedades cumplieron 2 criterios, 12 cumplieron al menos uno y 8 no cumplieron ninguno. CONCLUSIÓN: Las bases de datos clínico-administrativas detectaron comorbilidades como diabetes o hipertensión arterial pero no aportaron suficiente información para recoger las variables necesarias para hacer el ajuste de riesgo propuesto por el NSQIP para la medición de los efectos adversos en pacientes quirúrgicos

PURPOSE: The aim of this study was to assess the usefulness of clinical-administrative databases for the development of risk adjustment in the assessment of adverse events in surgical patients. METHODS: The study was conducted at the Hospital of Navarra, a tertiary teaching hospital in northern Spain. We studied 1602 hospitalizations of surgical patients from 2008 to 2010. We analysed 40 comorbidity variables included in the National Surgical Quality Improvement (NSQIP) Program of the American College of Surgeons using 2 sources of information: The clinical and administrative database (CADB) and the data extracted from the complete clinical records (CR), which was considered the gold standard. Variables were catalogued according to compliance with the established criteria: sensitivity, positive predictive value and kappa coefficient > 0.6. RESULTS: The average number of comorbidities per study participant was 1.6 using the CR and 0.95 based on CADB (p < .0001). Thirteen types of comorbidities (accounting for 8% of the comorbidities detected in the CR) were not identified when the CADB was the source of information. Five of the 27 remaining comorbidities complied with the 3 established criteria; 2 pathologies fulfilled 2 criteria, whereas 11 fulfilled 1, and 9 did not fulfil any criterion. CONCLUSION: CADB detected prevalent comorbidities such as comorbid hypertension and diabetes. However, the CABD did not provide enough information to assess the variables needed to perform the risk adjustment proposed by the NSQIP for the assessment of adverse events in surgical patients

Validity of the clinical and administrative databases in detecting post-operative adverse events.

OBJECTIVE: Patient safety has become a major public health concern and a priority for multiple institutions. Assessment of the adverse events is a key element for measuring the quality of healthcare organizations. The aim of this study was to measure the validity of the clinical and administrative database (CADB) as a source of information for the detection of post-operative adverse events. DESIGN: The study design was cross-sectional. SETTING: The study was carried out at the Hospital de Navarra (north of Spain). PARTICIPANTS: The sample consisted of 1602 episodes of surgical hospitalization from nine surgical departments. Two sources of information were used: data extracted from the complete clinical record (CR), the gold standard, vs. the CADB. MAIN OUTCOMES: Rate of adverse events, sensitivity, positive predictive value and κ index were analysed for 28 types of post-operative adverse event. Each index was considered acceptable if it had a value >0.6. RESULTS: The rate of adverse events using the CADB was 12.5 vs. 24% using CR within 30 days of surgery (P = 0.0001) and 13.9% using CR during a hospital stay (P > 0.05). The overall sensitivity of the CADB in the detection of adverse events was 0.18, and the positive predictive value was 0.34. Two adverse events (accounted for 6% of the total events detected) had moderate validity and the rest poor validity. Forty-two per cent of the adverse events took place after patient discharge. CONCLUSIONS: Although the use of CADB is appealing, the present study suggests that it is of very limited value in the detection of adverse events post-operatively.
