Usefulness of a national hip fracture registry to evaluate the profile of patients in whom antiosteoporotic treatment is prescribed following hospital discharge.

This study was carried out to describe the profile of prescription of antiosteoporotic treatment at discharge after a hip fracture in the Spanish National Hip Fracture Registry. Prescription rates among hospitals ranged from 0 to 94% of patients discharged. The prescription rate was higher among patients with better cognitive and functional baseline status. PURPOSE: National hip fracture registries are useful for assessing current care processes. The goals of this study were as follows: first, to know the rate of antiosteoporotic prescription at discharge among hip fracture patients in hospitals participating in the Spanish National Hip Fracture Registry (RNFC); second, to compare the differences between treated and non-treated patients; third, to analyze patients' characteristics associated with antiosteoporotic prescription at discharge; and fourth, to evaluate whether there were differences in the profile of patients discharged from hospitals with high and low prescription rates. METHOD: Patients discharged after a fragility hip fracture in 2017 and participating in the RNFC were included. Demographic variables, cognitive and functional status, prefracture osteoporosis treatment, fracture type, anesthetic risk, hospital volume, and antiosteoporotic prescription at discharge were analyzed. Given that patients were clustered within hospitals, intraclass correlation was calculated and generalized estimating equations were fitted. RESULTS: A total of 6701 patients from 54 hospitals were included. Antiosteoporotic prescription at discharge was prescribed to 36.5% (CI95% 35.8-37.2%), with a wide inter-hospital variability (range 0-94%). The intraclass correlation due of clustering of patients within hospitals was 47.9%. Antiosteoporotic prescription was more likely in patients who were younger, lived at home, previously treated for osteoporosis, had better baseline functional and cognitive status, lower anesthetic risk, and were discharged from high-volume hospitals, all with p < 0.001. The general profile of patients discharged from hospitals with high and low rate of prescription was similar. CONCLUSIONS: There is a wide variability between hospitals regarding antiosteoporotic prescription after hip fracture. This is more likely to be initiated in patients with better clinical, functional, and mental status and in those discharged from hospitals with larger volumes of patients. These results offer insights regarding the selection of patients receiving secondary prevention and raises questions on who and how many should be treated.

Spanish National Hip Fracture Registry (RNFC): analysis of its first annual report and international comparison with other established registries.

Hip fracture registries have helped improve quality of care and reduce variability, and several audits exist worldwide. The results of the Spanish National Hip Fracture Registry are presented and compared with 13 other national registries, highlighting similarities and differences to define areas of improvement, particularly surgical delay and early mobilization. INTRODUCTION: Hip fracture audits have been useful for monitoring current practice and defining areas in need of improvement. Most established registries are from Northern Europe. We present the results from the first annual report of the Spanish Hip Fracture Registry (RNFC) and compare them with other publically available audit reports. METHOD: Comparison of the results from Spain with the most recent reports from another ten established hip fracture registries highlights the differences in audit characteristics, casemix, management, and outcomes. RESULTS: Of the patients treated in 54 hospitals, 7.208 were included in the registry between January and October 2017. Compared with other registries, the RNFC included patients ≥ 75 years old; in general, they were older, more likely to be female, had a worse prefracture ambulation status, and were more likely to have extracapsular fractures. A larger proportion was treated with intramedullary nails than in other countries, and spinal anesthesia was most commonly used. With a mean of 75.7 h, Spain had by far the longest surgical delay, and the lowest proportion of patients mobilized on the first postoperative day (58.5%). Consequently, development of pressure ulcers was high, but length of stay, mortality, and discharge to home remained in the range of other audits. CONCLUSIONS: National hip fracture registries have proved effective in changing clinical practice and our understanding of patients with this condition. Such registries tend to be based on an internationally recognized common dataset which would make comparisons between national registries possible, but variations such as age inclusion criteria and follow-up are becoming evident across the world. This variation should be avoided if we are to maximize the comparability of registry results and help different countries learn from each other's practice. The results reported in the Spanish RNFC, compared with those of other countries, highlight the differences between countries and detect areas of improvement, particularly surgical delay and early mobilization.

Obturator dislocation of total hip arthroplasty with disassembly of the prosthesis components and periprosthetic fracture in morbid obese patient.

INTRODUCTION: Anterior dislocation is a rare complication of total hip arthroplasty (THA). There exist only three cases in the literature. None of them report disassembly of the prosthesis components. We present a morbidly obese woman who suffered an irreducible obturator dislocation of an infected total hip arthroplasty (THA), due to uncontrolled adduction during an early debridement surgery. Following unsuccessful closed reduction attempts, a Vancouver B2 periprosthetic fracture and disassembly of the prosthetic components were observed. Two-stage revision THA was necessary to resolve the infection and restore hip functionality. In obturator dislocation, the femoral head prosthetic can be trapped in the obturator foramen, and this may disassemble the prosthesis components during reduction maneuvers; theres also risk of periprosthetic fracture. This mandate an open reduction of the joint. Patient obesity could be a determining factor for this rare type of hip arthroplasty dislocation. Obturator dislocation is an extremely rare complication of the total hip arthroplasty, whose reductions should be handled with caution given the risks of periprosthetic fractures. In most cases, an open reduction of the joint is required. CLINICAL IMPORTANCE: Our work is likely to be of great interest because it offers tips for the management of this rare complication based on our experience.

INTRODUCCIÓN: La luxación anterior es una complicación poco frecuente de la artroplastia total de cadera (ATC). Sólo existen tres casos en la literatura. Ninguno de ellos informa del desmontaje de los componentes de la prótesis. Presentamos el caso una mujer obesa que sufrió una luxación irreducible de una artroplastia total de cadera (THA), la cual estaba infectada, debido a la aducción no controlada durante una cirugía de desbridamiento temprano. Después de los intentos fallidos de reducción cerrada, se presentó una fractura periprotésica clasificada como Vancouver B2 y el desmontaje de los componentes protésicos. Ameritó cirugía de revisión en dos etapas, lo cual se realizó para resolver la infección y restaurar la funcionalidad de la cadera. En la luxación obturatriz, la cabeza femoral puede quedar atrapada en el agujero obturador y, como consecuencia, favorecer la disociación de los componentes protésicos al intentar la reducción, asimismo puede favorecer un brazo de palanca que produzca una fractura periprotésica. La obesidad puede ser un factor determinante para la producción de esta rara complicación. Por todo lo anterior, se recomienda considerar de entrada la reducción abierta. La luxación obturatriz es una complicación rara en la artroplastia total de cadera; su tratamiento puede ser difícil y asociarse a fracturas. La relevancia de este caso es que permite mostrar algunas estrategias de manejo para prevenir complicaciones catastróficas.

Spanish National Hip Fracture Registry (SNHFR): a description of its objectives, methodology and implementation.

OBJECTIVE: To ascertain the current situation and clinical variability of the provision of care for Hip Fracture (HF) in Spain and the factors related to it by using a National Registry (NHFR) with high patient numbers and territorial representation NHFR, and to compare results on a national and international level and propose standards and criteria to improve healthcare quality. DESIGN: Continuous registry for at least three years of a representative sample of patients admitted to Spanish hospitals due to HF using the Minimum Common Dataset - international Fragility Fracture Network (FFN) MCD, adapted for Spanish. STUDY SCOPE AND SUBJECTS: all patients over the age of 74 years who are hospitalized with a diagnosis of a fragility HF at the participating hospitals distributed throughout the Spanish territory. Initially 48 hospitals are included, and we expect to incorporate the highest number of sites possible. RESULTS: It is expected to ascertain the current situation of provision of care for HF in Spain. Each hospital will be offered information regarding their results and their situation compared to the rest. The results from national hospitals will be compared to others included in the registry and to hospitals abroad, which use the same database. Variability will be studied, care standards will be established, and objectives will be proposed for the continuous improvement of the care process of this condition.

Historical and political implications of haemophilia in the Spanish royal family.

The political implications of haemophilia in the marriage of King Alfonso XIII of Spain and Princess Victoria Eugenie Battenberg of England have been reviewed in recent books on history. However, the fact that they had haemophilic sons also affected their personal relationship. In this article, we review the consequences haemophilia bore on their lives. We feel great compassion for families who suffer the illness, be it ordinary people or members of royalty; however, in this case, it can be said that when the disease affected a royal couple, the political consequences were great.
