Cerebrospinal Fluid Output as a Risk Factor of Chronic Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage.

BACKGROUND: Chronic shunt-dependent hydrocephalus is a well-known complication of subarachnoid hemorrhage. Although the risk factors have been extensively investigated, most fail to predict permanent shunt dependency. It is unknown whether the volume of cerebrospinal fluid (CSF) from external ventricular drainage and the daily volume of drainage during the acute hydrocephalus phase (first 72 hours) can predict shunt dependency. We aimed to determine whether CSF output during the acute hydrocephalus phase is a risk factor for shunt dependency. METHODS: Patients with aneurysmal subarachnoid hemorrhage and hydrocephalus treated with external ventricular drainage were prospectively registered in our database between January 2017 and March 2020. Factors evaluated for predicting shunt dependency included age; sex; Hunt and Hess grade; World Federation of Neurological Surgeons grade; acute hydrocephalus; modified Fisher grade; aneurysm treatment modality; hospital length of stay; modified Rankin score; average daily overall CSF production; average CSF output for the first 24, 48, and 72 hours; external ventricular drainage days; the number of wean/clamp failures; and ventriculoperitoneal shunting. RESULTS: Univariate analysis identified Hunt and Hess grade; acute hydrocephalus at onset; external ventricular drainage; overall CSF output; average CSF output for the first 24, 48, and 72 hours; and CSF output until the first clamp as significant risk factors for shunt dependency (P < 0.001). In a multivariate logistic regression analysis, overall CSF output and average CSF output for the first 72 hours were significant risk factors for shunt dependency. CONCLUSIONS: Overall CSF output, especially during the acute hydrocephalus phase (first 72 hours), predicts the development of chronic hydrocephalus.

Validation of shunt dependency prediction scores after aneurysmal spontaneous subarachnoid hemorrhage.

BACKGROUND: Currently available scores for predicting shunt dependency after aneurysmal spontaneous subarachnoid hemorrhage (aSAH) are limited and not widely accepted. The key purpose of this study was to validate a recently created score for shunt dependency in aSAH (SDASH) in an independent population of aSAH patients. We compared this new SDASH score based on a combination of the Hunt and Hess grade, Barrow Neurological Institute (BNI) score, and the presence or not of acute hydrocephalus with other published predictive scores. METHODS: The SDASH score, Hijdra score, BNI grading system, chronic hydrocephalus ensuing from SAH score (CHESS), Graeb score, and modified Graeb score (mGS) were calculated for a cohort of aSAH patients. Logistic regression analysis was used to determine the reliability of the SDASH score, and the area under the curve (AUC) of the receiver operating characteristics (ROC) curve was used to assess the discriminative ability of the model. RESULTS: In 214 patients with aSAH, 40 (18.7%) developed shunt-dependent hydrocephalus (SDHC). The AUC for the SDASH score was 0.816. The SDASH score reliably predicted SDHC in aSAH (odds ratio: 2.93, 95% CI: 1.99-4.31; p < 0.001) with no statistically significant differences being found between the SDASH score and the CHESS score (AUC: 0.816), radiological-based Graeb score (AUC: 0.742), or modified Graeb score (AUC: 0.741). However, the Hijdra score (AUC: 0.673) and BNI grading system (AUC: 0.616) showed lower predictive values than the SDASH score. CONCLUSIONS: Our findings support the ability of the SDASH score to predict shunt dependency after SAH in a population independent to that used to develop the score. The SDASH score may aid in the early management of hydrocephalus in aSAH, and it does not differ greatly from other predictive scores.

Análisis descriptivo de la formación en participación comunitaria en salud en España / Descriptive analysis of training in community health engagement in Spain

OBJETIVO: Describir las actividades formativas en participación comunitaria en salud que se realizan en España. MÉTODO: Identificación y análisis descriptivo de las acciones formativas en el periodo 2017-2018 en los ámbitos de la universidad, la Administración pública y las unidades docentes de medicina y enfermería familiar y comunitaria. RESULTADOS: Se incluyeron 28 actividades formativas en el análisis descriptivo de ocho comunidades autónomas diferentes y dos de ámbito nacional. La mayoría de las actividades formativas son presenciales e impartidas por unidades docentes de formación especializada para profesionales de medicina y enfermería de atención familiar y comunitaria, con una duración de entre 10 y 25 horas, y sin coste de matriculación. CONCLUSIÓN: Existe un vacío formativo en la mayoría de las comunidades autónomas que evidencia que la formación en participación comunitaria en salud es escasa y está poco integrada. Las actividades formativas analizadas están incluidas principalmente en la formación de especialistas de medicina y enfermería de familia y comunitaria, si bien esta formación no está unificada ni se incorpora en todos los planes docentes. Para una mirada integral sobre la salud de las personas es esencial incluir la participación comunitaria en salud en la formación de grado y posgrado, tanto del ámbito sanitario como de otras disciplinas. Las instituciones responsables de la formación en los diferentes niveles deben incluir la participación comunitaria en salud en los itinerarios formativos de los profesionales

OBJECTIVE: To describe the professional training health professionals receive in community health engagement in Spain. METHOD: The identification and descriptive analysis of trainings developed between 2013-2018 offered by public universities, public administrations and the teaching units for the specialization of family and community health doctors and nurses. RESULTS: Twenty eight trainings were included in the descriptive analysis. Most of them had been organized during 2018 in eight Autonomous Communities. Two of them were organized at a national level. Most trainings were attendance based and have been developed by teaching units in charge of training doctors and nurses specializing in family and community health, with an average duration of 10-25hours and no enrolment costs. CONCLUSION: There is a lack of training in community health engagement in the majority of autonomous communities in Spain which shows that it is scarce and not yet fully integrated in the training of health professionals. The trainings that have been analyzed are mainly part of wider specialization programs for doctors and nurses specializing in family and community health, and even so this training is not standardized and included in the specialization programs of all the Spanish regions. To develop a comprehensive health approach it is key to include community health engagement as part of the trainings professionals receive during their University degree, and to extend it to other health professions. The institutions responsible for the training of health professionals should include community health engagement as part of the different training itineraries of professionals

Comparison of elevated intracranial pressure pulse amplitude and disproportionately enlarged subarachnoid space (DESH) for prediction of surgical results in suspected idiopathic normal pressure hydrocephalus.

BACKGROUND: To compare the prognostic value of pulse amplitude on intracranial pressure (ICP) monitoring and disproportionately enlarged subarachnoid space hydrocephalus (DESH) on magnetic resonance imaging (MRI) for predicting surgical benefit after shunt placement in idiopathic normal pressure hydrocephalus (iNPH). METHOD: Patients with suspected iNPH were prospectively recruited from a single centre. All patients received preoperative MRI and ICP monitoring. Patients were classified as shunt responders if they had an improvement of one point or more on the NPH score at 1 year post-surgery. The sensitivity, specificity, Youden index, and positive and negative predictive values of the two diagnostic methods were calculated. RESULTS: Sixty-four of 89 patients clinically improved at 1 year post-surgery and were classed as shunt responders. Positive DESH findings had a sensitivity of 79.4 % and specificity of 80.8 % for predicting shunt responders. Fifty-five of 89 patients had positive DESH findings: 50 of these responded to VP shunt, giving a positive and negative predictive value of 90.9 % and 61.8 %, respectively. Fifty-seven of 89 patients had high ICP pulse amplitude. High ICP pulse amplitude had a sensitivity of 84.4 %, specificity of 88 %, positive predictive value of 94.7 % and negative predictive value of 61.8 % for predicting shunt responders. CONCLUSIONS: Both positive DESH findings and high ICP pulse amplitude support the diagnosis of iNPH and provide additional diagnostic value for predicting shunt-responsive patients; however, high ICP amplitude was more accurate than positive DESH findings, although it is an invasive test.
