Evaluación del dolor en el adulto mayor / Evaluation of the pain in older people

Resumen: Objetivo: Comparar las informaciones obtenidas del porcentaje verbal de mejoría declarada verbalmente con la escala visual analógica (EVA) en personas con edad menor y mayor o igual de 65 años. Pacientes y métodos: Fueron evaluados 95 individuos con dolor agudo en el hombro (entesitis). Fue solicitado en cada uno de ellos medir la intensidad del dolor a través de la EVA tras un tratamiento médico con infiltración de corticosteroide en el hombro; fueron examinados una semana después, con una nueva medición de la intensidad del dolor verbalmente. Enseguida, las informaciones fueron comparadas entre pacientes con edad mayor o igual y menor de 65 años. Resultados: Se utilizó una diferencia de hasta 10% en módulo (valor absoluto) entre el porcentaje verbalmente declarado y el calculado con base en las medidas declaradas en la EVA. En los sujetos < 65 años, la frecuencia de casos donde la variación entre el porcentaje de mejoría verbalmente declarado y el calculado excede 10% fue de 29.8%; entre las personas ≥ 65 años la discrepancia ocurrió en 60.95%. Conclusión: El análisis de este estudio utilizó distintos métodos descriptivos e inferenciales para investigar las hipótesis levantadas; dentro de las herramientas empleadas, una confirma la hipótesis sobre los individuos ≥ 65 años y nos lleva a recomendar que el uso de la EVA para este grupo etario sea realizado con cautela y orientación.

Abstract: Objective: To compare the information obtained of the percentage of improvement declared orally with the improvement marked in the visual analogical scale (VAS) in patients under and over 65 years of age. Patients and methods: Ninety-five individuals with acute shoulder pain (enthesitis) were evaluated. The subjects were requested to mark the pain intensity in the VAS before a treatment with corticosteroid injection in the shoulder and were evaluated again through the VAS one week after the procedure. They were also requested to declare orally the pain intensity. Then, the information was compared between patients aged under and over 65 years of age. Results: 29.8% of those younger than 65 years, and 60.95% of those older than that age presented more than 10% difference between orally stated and calculated pain relief percentage based on the VSA. Conclusion: The difference between the orally stated and the calculated pain relief percentage based on the VSA was significantly higher in the group of those older than 65 years. This finding proved that the VAS is a poor method to evaluate pain relief in the senior population.

Ottawa ankle rules and subjective surgeon perception to evaluate radiograph necessity following foot and ankle sprain.

BACKGROUND: Foot and ankle injuries are frequent in emergency departments. Although only a few patients with foot and ankle sprain present fractures and the fracture patterns are almost always simple, lack of fracture diagnosis can lead to poor functional outcomes. AIM: The present study aims to evaluate the reliability of the Ottawa ankle rules and the orthopedic surgeon subjective perception to assess foot and ankle fractures after sprains. SUBJECTS AND METHODS: A cross-sectional study was conducted from July 2012 to December 2012. Ethical approval was granted. Two hundred seventy-four adult patients admitted to the emergency department with foot and/or ankle sprain were evaluated by an orthopedic surgeon who completed a questionnaire prior to radiographic assessment. The Ottawa ankle rules and subjective perception of foot and/or ankle fractures were evaluated on the questionnaire. RESULTS: Thirteen percent (36/274) patients presented fracture. Orthopedic surgeon subjective analysis showed 55.6% sensitivity, 90.1% specificity, 46.5% positive predictive value and 92.9% negative predictive value. The general orthopedic surgeon opinion accuracy was 85.4%. The Ottawa ankle rules presented 97.2% sensitivity, 7.8% specificity, 13.9% positive predictive value, 95% negative predictive value and 19.9% accuracy respectively. Weight-bearing inability was the Ottawa ankle rule item that presented the highest reliability, 69.4% sensitivity, 61.6% specificity, 63.1% accuracy, 21.9% positive predictive value and 93% negative predictive value respectively. CONCLUSION: The Ottawa ankle rules showed high reliability for deciding when to take radiographs in foot and/or ankle sprains. Weight-bearing inability was the most important isolated item to predict fracture presence. Orthopedic surgeon subjective analysis to predict fracture possibility showed a high specificity rate, representing a confident method to exclude unnecessary radiographic exams.
