The Role of Physical Exercise in Chronic Musculoskeletal Pain: Best Medicine-A Narrative Review.

The aim of this paper is to provide a narrative review of the effects of physical exercise in the treatment of chronic musculoskeletal pain. Physical inactivity and sedentary behavior are associated with chronic musculoskeletal pain and can aggravate it. For the management of musculoskeletal pain, physical exercise is an effective, cheap, and safe therapeutic option, given that it does not produce the adverse effects of pharmacological treatments or invasive techniques. In addition to its analgesic capacity, physical exercise has an effect on other pain-related areas, such as sleep quality, activities of daily living, quality of life, physical function, and emotion. In general, even during periods of acute pain, maintaining a minimum level of physical activity can be beneficial. Programs that combine several of the various exercise modalities (aerobic, strengthening, flexibility, and balance), known as multicomponent exercise, can be more effective and better adapted to clinical conditions. For chronic pain, the greatest benefits typically occur with programs performed at light-to-moderate intensity and at a frequency of two to three times per week for at least 4 weeks. Exercise programs should be tailored to the specific needs of each patient based on clinical guidelines and World Health Organization recommendations. Given that adherence to physical exercise is a major problem, it is important to empower patients and facilitate lifestyle change. There is strong evidence of the analgesic effect of physical exercise in multiple pathologies, such as in osteoarthritis, chronic low back pain, rheumatoid arthritis, and fibromyalgia.

The three horizons model applied to medical science.

The three horizons model is a framework that helps manage an organization's innovation strategy. This model considers three aspects (horizons) that should be present in the institution and guide the development of new systems. Applied to medical science, the horizons are considered as paradigms that set the guidelines for clinical knowledge. New technologies can influence this model by causing disruptive changes. Horizon 1 (evidence-based medicine) reflects the current paradigm and emphasizes the aspect of continuous improvement needed to strengthen it, such as with the introduction of the GRADE (Grades of Recommendation Assessment, Development, and Evaluation) methodology. Evidence-based medicine has made it possible to stop performing harmful interventions like autologous bone marrow or stem cell transplantation in cancer treatment for women with early poor prognosis breast cancer or to discontinue the erroneous belief that children should not sleep on their backs to prevent sudden infant death syndrome. Horizon 2 (real-world evidence) refers to a new model in which innovation has generated new capabilities. This change makes it possible to correct weaknesses of the previous paradigm, as in the case of pragmatic clinical trials. Real-world evidence has been used to show that drugs such as tofacitinib are effective without using methotrexate as background or to demonstrate the efficacy of chemotherapy in older patients with stage II colon cancer. Horizon 3 (precision medicine) involves a disruptive innovation, leading to the abandonment of the traditional mechanistic model of medical science and is made possible by the appearance of major advances such as artificial intelligence. Precision medicine has been used to assess the use of retigabine for the treatment of refractory epilepsy or to define a genome-adjusted radiation dose using a biological model to simulate the response to radiotherapy, facilitate dose adjustment and predict outcome in breast cancer.

Repercusión de un sistema centralizado de ingresos sobre la eficacia y eficiencia de una unidad geriátrica de recuperación funcional / Impact of a centralised hospital admission system on the efficacy and efficiency of a geriatric functional recovery unit

OBJETIVO: Evaluar la influencia del cambio en la gestión de ingresos en una unidad geriátrica de recuperación funcional (UGRF) sobre su actividad y resultados asistenciales. MATERIAL Y MÉTODOS: Estudio observacional retrospectivo. Se recogieron datos registrados desde el año 2000 de la UGRF del Hospital Central Cruz Roja, agrupados en periodos de 4 años, salvo los ingresos centralizados (septiembre de 2016-diciembre de 2018). Los datos recogidos al ingreso fueron Escala Funcional y Mental de Cruz Roja, índice de Barthel, diagnóstico principal motivo del deterioro funcional (que se agrupó en ictus, patología ortopédica y cuadros de inmovilidad multifactorial) y comorbilidad evaluada por el índice de Charlson. Como variables de resultado se estudiaron la ganancia funcional al alta, tanto global como relativa, la estancia hospitalaria, la eficiencia funcional, las altas a residencia y los retraslados a unidad de agudos. Analizamos la relación entre los ingresos realizados de manera centralizada desde una unidad externa y el periodo previo (ingresos gestionados directamente desde la UGRF) en las variables resultados utilizando un análisis multivariante (regresión lineal para variables resultado continuas y regresión logística para las dicotómicas) ajustado por variables al ingreso. RESULTADOS: En el análisis multivariante los pacientes ingresados desde la unidad central presentaron una mayor ganancia funcional global y relativa (diferencia de medias de 3,49 puntos con IC 95%=1,65-5,33 y 12,41% con IC 95%=0,74-24,08, respectivamente), mayor estancia (12,92 días; IC 95%=11,54-14,30) y menor eficiencia (−0,36; IC 95%=−0,16 a −0,57), mayor riesgo de institucionalización (OR 1,61; IC 95%=1,19-2,16) y riesgo de retraslado a unidad de agudos (OR 3,16; IC 95%=2,24-4,47). CONCLUSIONES: El sistema centralizado de ingreso influyó en la mejora de parámetros funcionales, pero a costa de una mayor estancia y una menor eficiencia asistencial, objetivándose un incremento de la institucionalización al alta y de los retraslados a unidades de agudos

OBJECTIVE: To evaluate the influence of a change in the management of admissions on the activity and care outcomes of a Geriatric Functional Recovery Unit (GFRU). MATERIAL AND METHODS: A retrospective observational study was conducted. Since 2000, the Hospital Central Cruz Roja GFRU has been collecting data grouped into periods of 4 years, except for the centralised admissions (September 2016-December 2018). The data collected on admission included the Red Cross Functional and Mental scales, the Barthel index, the main diagnosis of the functional decline (grouped into stroke, orthopaedic problem, and multifactorial immobility episodes), and comorbidity evaluated by the Charlson index. The following outcome variables were analysed: the overall and relative functional gain at discharge; length of hospital stay; the functional efficiency, discharges to nursing homes, and transfers to acute care units. An analysis was made of the relationship between the admissions from the centralised unit and the previous period (directly admission managed by GFRU), using multivariate analysis (linear regression for continuous outcome variables and logistic regression for the dichotomous ones), adjusted for admission variables. RESULTS: Patients admitted from the centralised unit showed a greater overall and relative functional gain (difference between both means: 3.49 points, 95% CI; 1.65-5.33, and 12.41%, 95% CI; 0.74-24.08, respectively), longer stay (12.92 days, 95% CI; 11.54-14.30) and lower efficiency (−0.36, 95% CI; −0.16 to −0.57), higher risk of institutionalisation (OR 1.61, 95% CI; 1.19-2.16), and transfers to acute care units (OR 3.16, 95% CI; 2.24-4.47). CONCLUSIONS: A centralised admissions system had an influence on the improvement of functional parameters in the patients, but with a longer length of hospital stay, and lower efficiency. Increases in institutionalisation at discharge and transfers to acute care units were also observed
