RESUMO

Background: The prognosis and mortality in patients with COVID-19 are variable. The NEWS2 (National Early Warning Score) and REMS (Rapid Emergency Medicine Score) scales can be used quickly at hospital admission to predict mortality, no studies have been found that compare their predictive performance in our population. Objective: To compare NEWS2 and REMS to predict mortality in patients with COVID-19. Material and methods: Retrospective cohort with 361 patients. The variables were collected to calculate the NEWS2 and REMS scales and the reason for hospital discharge. The predictive value for mortality was analyzed using the ROC curve, establishing the area under the curve (AUC) with 95% confidence intervals (95% CI). The cut-off point (PC) with the best sensitivity and specificity, positive predictive value (PPV) and negative predictive value (NPV), as well as relative risk (RR) with 95% CI. Results: The AUC of NEWS2 and REMS were 0.929 (95% CI: 0.903-0.956) and 0.913 (95% CI: 0.884-0.943), respectively. The PC of the NEWS2 scale was 8 points, with sensitivity 87.8% and specificity 82.1%, PPV 69.7% and NPV 93.5% and of the REMS scale of 7 points, with sensitivity 83.5% and specificity 83.7%, PPV 70.5% and NPV 91.6%. 8 or more points on the NEWS2 scale presenting a RR of 10.74 (95% CI: 6.4-18.03), and REMS 7 or more points RR 8.36 (95% CI: 5.36-13.02). Conclusion: Both tests presented good discriminative ability to predict mortality, being better according to AUC and RR in the NEWS2 scale.


Introducción: el pronóstico y mortalidad en pacientes con COVID-19 son variables. Las escalas NEWS2 (National Early Warning Score) y REMS (Rapid Emergency Medicine Score) pueden ser utilizadas rápidamente al ingreso hospitalario para predecir mortalidad, sin embargo no se encuentran estudios que comparen su rendimiento predictivo en nuestra población. Objetivo: comparar las escalas NEWS2 y REMS para predecir mortalidad en pacientes con COVID-19. Material y métodos: cohorte retrospectiva con 361 pacientes. Se recabaron las variables para calcular las escalas NEWS2 y REMS y el motivo de egreso hospitalario. El valor predictivo para mortalidad se analizó mediante curva COR, estableciendóse área bajo la curva (AUC) con intervalos de confianza al 95% (IC95%). Se determinó el punto de corte (PC) con la mejor sensibilidad y especificidad, valor predictivo positivo (VPP) y valor predictivo negativo (VPN), además de riesgo relativo (RR) con IC95%. Resultados: las AUC de NEWS2 y REMS fueron de 0.929 (IC95%: 0.903 - 0.956) y 0.913 (IC95%: 0.884 - 0.943), respectivamente. El PC de la escala NEWS2 fue de 8 puntos, con sensibilidad de 87.8% y especificidad de 82.1%, el VPP de 69.7% y el VPN de 93.5%; mientras que de la escala REMS fue de 7 puntos, con sensibilidad de 83.5% y especificidad de 83.7%, el VPP de 70.5% y el VPN de 91.6%. Un total de 8 o más puntos en la escala NEWS2 presentan un RR de 10.74 (IC95%: 6.4 - 18.03), y REMS de 7 o más puntos un RR de 8.36 (IC95%: 5.36 - 13.02). Conclusión: ambas pruebas presentaron buena capacidad discriminativa para predecir mortalidad, siendo mejor de acuerdo con AUC y RR en la escala NEWS2.

RESUMO

Introducción: en México 130 000 personas viven con enfermedad renal crónica (ERC). Las afecciones cardiacas son los problemas clínicos más frecuentes; 45% de las muertes de pacientes en terapia sustitutiva tienen un origen cardiaco. Objetivo: identificar la probabilidad de presentar falla cardiaca aguda (FCA) en pacientes con ERC en el Servicio de Urgencias Adultos de un hospital de segundo nivel. Material y métodos: estudio de casos (111) y controles (103). Los casos se definieron como pacientes con ERC ingresados a Urgencias por FCA comparados con controles, pacientes con ERC que ingresaron por otro diagnóstico diferente. Se realizó regresión logística binaria y se determinaron razones de momios (RM) e intervalos de confianza al 95% (IC 95%). Un valor de p ˂ 0.05 fue significativo. Resultados: la hipertensión arterial (RM 7.12, IC 95% 2.3-22.06, p = 0.01), el uso de 3 o más antihipertensivos (RM, 2.903, IC 95% 1.19-7.11, p = 0.02), empleo de inhibidores de la enzima convertidora de angiotensina (IECA) (RM 4.25, IC 95% 1.78-10.09, p = 0.01), antagonistas de los receptores de angiotensina-II (ARA-II) (RM 2.41, IC 95% 1.19-4.89, p = 0.014), diuréticos (RM 42.87, IC 95% 9.02-203.63, p = 0.00), diálisis peritoneal (RM 2.48, IC 95% 1.25-4.81, p = 0.009) y hemodiálisis (RM 0.40, IC 95% 0.20-0.79, p = 0.009) tuvieron significación estadística. Conclusiones: los pacientes con ERC con hipertension arterial, empleo de IECA, ARA-II, diuréticos y en dialisis peritoneal, tuvieron mayor probabilidad de presentar falla cardiaca aguda, mientras que los pacientes que se encontraban en hemodiálisis tuvieron menor probabilidad.


Background: In Mexico 130,000 people live with chronic kidney disease (CKD). Heart conditions are the most frequent clinical problems; 45% of the deaths of patients in replacement therapy have a cardiac origin. Objective: To identify the probability of presenting acute heart failure (AHF) in patients with CKD in the Adult Emer- gency Department (AED) of a second-level hospital. Material and methods: Case-control study with 111 cases and 103 controls. Cases were defined as patients with CKD admitted to AED for AHF compared with controls: patients with CKD who were admitted for a different diagnosis. Binary logistic regression was performed and odds ratio (OR) and 95% confidence intervals (95% CI) were determined. A value of p ˂ 0.05 was considered significant. Results: Arterial hypertension (OR 7.12, 95% CI 2.3-22.06, p = 0.01), the use of 3 or more antihypertensive drugs (OR 2.903, 95% CI 1.19-7.11, p = 0.02), the use of inhibitors of angiotensin converting enzyme (ACE inhibitors) (OR 4.25, 95% CI 1.78-10.09, p = 0.01), angiotensin II receptor blockers (ARBs) (OR 2.41, 95% CI 1.19-4.89, p = 0.014), diuretics (OR 42.87, 95% CI 9.02-203.63, p = 0.00), peritoneal dialysis (OR 2.48, 95% CI 1.25-4.81, p = 0.009) and hemodialysis (OR 0.40, 95% CI 0.20-0.79, p = 0.009) had statistical significance. Conclusions: CKD patients with arterial hypertension, use of ACE inhibitors, ARBs, diuretics and peritoneal dialysis were more likely to present AHF, while patients who were on hemodialysis were less likely to presenting it.
