RESUMO
INTRODUCTION: Objective: to describe an evaluation of interobserver agreement in the use of a checklist related to the use of nasoenteral tube (NSS) as a presupposition for quality in obtaining data. Method: a methodological study conducted in 2018 in a Brazilian hospital, preceding the data collection of an open-label clinical trial. Independent observers, blinded to the evaluation of their peers, evaluated patients with NSS through a 25-item checklist. The data collected by eight previously trained research assistants (RA) were compared to those obtained by an experienced nurse (reference standard). Agreement was measured using the kappa coefficient and PABAK. Results: a total of 451 observations were made in pairs. Considering the total items on the checklist there was almost perfect agreement (k > 0.80) in all observation pairs (nurse vs. each RA): RA 1 (k = 0.91; 95 % CI = 0.89-0.93); RA 2 (k = 0.83; 95 % CI = 0.80-0.85); RA 3 (k = 0.92; 95 % CI = 0.90-0.94); RA 4 (k = 0.83; 95 % CI = 0.80-0.86); RA 5 (k = 0.94; 95 % CI = 0.92-0.96); RA 6 (k = 0.94; 95 % CI = 0.92-0.96); RA 7 (k = 0.96; 95 % CI = 0.95-0.98); RA 8 (k = 0.73; 95 % CI = 0.70-0.77). However, for isolated items, and in specific RAs, there were fair agreements, unacceptable to effectively collect data from a clinical trial. Retraining and supervision of RAs were able to improve agreement between observers. Conclusion: an evaluation of interobserver agreement proved to be fundamental to ensure the reliability of data collection and, therefore, to avoid measurement biases.
INTRODUCCIÓN: Objetivo: describir una evaluación de la concordancia entre observadores en el uso de una lista de verificación en la atención a pacientes con sonda nasoenteral (SNE) como premisa de la recogida de datos. Método: este estudio de fiabilidad se realizó en 2018 en un hospital brasileño, antes de la recogida de datos para un ensayo clínico abierto. Ocho observadores independientes, previamente capacitados y "cegados" con respecto a las evaluaciones de los demás, evaluaron a pacientes con SNE por medio de una lista de comprobación de 25 elementos. Los datos obtenidos por estos asistentes de investigación (AI) se compararon con los obtenidos por una enfermera experimentada. Se midió la concordancia mediante los coeficientes kappa y PABAK. Resultados: se realizaron 451 observaciones por pares. Considerando la totalidad de los elementos, hubo una concordancia casi perfecta (k > 0,80) en todos los pares de observación (enfermera vs. cada AI): AI 1 (k = 0,91; IC95 % = 0,89-0,93); AI 2 (k = 0,83; IC95 % = 0,80-0,85); AI 3 (k = 0,92; IC95 %= 0,90-0,94 ); AI 4 (k = 0,83; IC95 % = 0,80-0,86); AI 5 (k = 0,94; IC95 % = 0,92-0,96); AI 6 (k = 0,94; IC95 % = 0,92-0,96); AI 7 (k = 0,96; IC95 % = 0,95-0,98); AI 8 (k = 0,73; IC95 % = 0,70-0,77). Se identificó un menor número de concordancia en los elementos individuales y en determinados AI. La recapacitación y supervisión de los AI mejoró su desempeño y la concordancia entre observadores. Conclusión: la evaluación de la concordancia entre observadores resultó fundamental para asegurar la fiabilidad de la recogida de datos y, por consiguiente, evitar sesgos de medición en los estudios clínicos de enfermería.

We conducted a quasi-experimental study to evaluate a bundle to prevent nonventilator hospital-acquired pneumonia (NV-HAP) in patients on enteral tube feeding. After the intervention, there was an increase in bundle compliance from 55.9% to 70.5% (P < .01) and a significant decrease (34%) in overall NV-HAP rates from 5.71 to 3.77 of 1,000 admissions.

OBJECTIVE: Verify whether the postoperative fasting period increases the risk for infection and prolonged length of stay. METHODS: Prospective cohort study. Elective surgery patients were included. Excluded: those with no conditions for nutritional assessment, admitted in minimal care units, as well as with <72h in-hospital stay. Postoperative fasting was recorded from the days of no nutrition therapy. The length of stay was considered prolonged when above the average according to the specialty and type of surgery. Logistic regression was used to assess associations and adjust for confounding factors. RESULTS: 521 patients were analyzed, 44.1% were fasted for a period ≥1 day, 91% for ≥3 days and 5.6% for more than 5 days. Patients with more than 5 days fasting were more eutrophic, more admitted to intensive care units, and had more postoperative surgical complications. After adjustment for confounding variables, it was noted that ≥1 day of postoperative fasting increased the infection risk by 2.04 (CI95%: 1.20 to 3.50), ≥3 days 2.81 (CI95%: 1.4-5.8), and in fasting for more than 5 days the infection risk was 2.88 times higher (CI95%: 1.17 to 7.16). The risk for prolonged hospitalization was 2.4 (CI95%: 1.48 to 3.77) among patients who had ≥1 day fasting, 4.44 (CI95%: 2.0 to 9.8)and 4.43 times higher (CI95%: 1.73 to 11.3) among patients with ≥3 days fasting and more than 5 days, respectively. CONCLUSION: The longer duration of postoperative fasting was an independent risk factor both for infection and for prolonged hospital stay.

Pressure ulcers (PU) may increase the incidence of hospital complications, and one should prevent this damage. The Braden Scale stands out as a tool to assess the risk of PU. The study aimed to identify changes in the score of the Braden subscales are associated with the risk of developing PCU. Logistic regression was used in a retrospective cohort study conducted in Hospital de Clínicas de Porto Alegre in adults hospitalized in surgical clinical units from October 2005 to June 2006. We evaluated the records database of 1503 patients with a mean aged 55.5 +/- 16 years, 52.7% female. The incidence of PU was 1.8% and was associated with diabetes and heart failure. There was a higher PU in patients worst in sensory perception, mobility, and activity and the presence of moisture. No association was found between nutrition and PU. Except nutrition, the other Braden sub-scales shown to be predictive of PU.

PURPOSE OF REVIEW: Vitamin K is an essential co-factor for the synthesis of several coagulation factors. Oral anticoagulants competitively inhibit enzymes that participate in vitamin K metabolism. The purpose of this review is to evaluate the potential interaction of dietary vitamin K and coagulation stability, particularly in the elderly patient. RECENT FINDINGS: Recent prospective evidences suggest that dietary vitamin K plays an essential role in anticoagulation stability. Vitamin K intake of more than 250 microg/day was shown to decrease warfarin sensitivity in anticoagulated patients consuming regular diets. In a randomized crossover study, brief periods of changes on vitamin K intake also had significant effects on coagulation parameters. Patients that were allocated to an 80% decrease of intake increased International Normalized Ratio (INR) by almost 30% 7 days after the intervention. Similarly, it was estimated by dietary records that for each increase in 100 microg of vitamin K intake, the INR would be reduced by 0.2. A recent study also demonstrated that over-the-counter multivitamin supplements contain enough vitamin K1 to significantly alter coagulation parameters. SUMMARY: Contemporary data strengthen the concept that the interaction between dietary vitamin K and coumarin derivatives is clinically relevant and plays a major role in INR fluctuations in chronic anticoagulated patients.
