Is hospital discharge administrative data an appropriate source of information for cancer registries purposes? Some insights from four Spanish regist…
2010
Abstract Background The use of hospital discharge administrative data (HDAD) has been recommended for automating, improving, even substituting, population-based cancer registries. The frequency of false positive and false negative cases recommends local validation. Methods The aim of this study was to detect newly diagnosed, false positive and false negative cases of cancer from hospital discharge claims, using four Spanish population-based cancer registries as the gold standard. Prostate cancer was used as a case study. Results A total of 2286 incident cases of prostate cancer registered in 2000 were used for validation. In the most sensitive algorithm (that using five diagnostic codes), e…
Bladder cancer index: cross-cultural adaptation into Spanish and psychometric evaluation.
2014
Background: The Bladder Cancer Index (BCI) is so far the only instrument applicable across all bladder cancer patients, independent of tumor infiltration or treatment applied. We developed a Spanish version of the BCI, and assessed its acceptability and metric properties. Methods: For the adaptation into Spanish we used the forward and back-translation method, expert panels, and cognitive debriefing patient interviews. For the assessment of metric properties we used data from 197 bladder cancer patients from a multi-center prospective study. The Spanish BCI and the SF-36 Health Survey were self-administered before and 12 months after treatment. Reliability was estimated by Cronbach’s alpha.…
The Multicultural Personality Questionnaire (SF-40): Adaptation and Validation of the Spanish Version.
2021
The coexistence of diverse cultures in our society indicates the need to examine the factors related to the success of multicultural interactions. The study aims were to examine the psychometric characteristics of the Spanish version of the Multicultural Personality Questionnaire short form (MPQ-SF40), in a convenience sample of 392 university students. Then, the effect of sex and age was assessed, and finally, the levels and percentiles of multicultural personality were measured. The scale’s validity was assessed with exploratory and confirmatory factor analysis (EFA and CFA). Reliability was evaluated with Cronbach’s alpha, composite reliability (CR), and average variance extracted (AVE).…
HIDRAdisk: validation of an innovative visual tool to assess the burden of hidradenitis suppurativa
2019
Background: Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disease characterized by painful inflamed nodules, recurrent abscesses and fistulas located in apocrine gland–bearing body sites. The negative impact of HS on patient's quality of life (QoL) has been reported to be greater than other dermatologic conditions as psoriasis and atopic eczema, and its improvement is an important goal in disease management. Nowadays, there are no specific validated QoL instruments available for HS and generic dermatologic questionnaires are used. Objective: The objective of this study was to demonstrate the validity, reliability and responsiveness of HIDRAdisk, a new innovative t…
Development of a universal short patient satisfaction questionnaire on the basis of SERVQUAL: Psychometric analyses with data of diabetes and stroke …
2019
ObjectiveA short questionnaire which can be applied for assessing patient satisfaction in different contexts and different countries is to be developed.MethodsSix items addressing tangibles, reliability, responsiveness, assurance, empathy, and communication were analysed. The first five items stem from SERVQUAL (SERVice QUALity), the last stems from the discussion about SERVQUAL. The analyses were performed with data from 12 surveys conducted in six different countries (England, Finland, Germany, Greece, the Netherlands, Spain) covering two different conditions (type 2 diabetes, stroke). Sample sizes for included participants are 247 in England, 160 in Finland, 231 in Germany, 152 in Greece…
Use of QT intervals for a more accurate diagnose of syncope and evaluation of syncope severity.
2014
Abstract BACKGROUND: This study aimed to evaluate the use of QT intervals, their diagnostic predictive value in patients with syncope and their relationship with syncope severity. METHODS: One hundred and forty nine patients with a diagnosis of syncope were admitted to Internal Medicine departments at the University of Palermo, Italy, between 2006 and 2012, and 140 control subjects hospitalised for other causes were enrolled. QT maximum, QT minimum, QTpeak, QT corrected, QT dispersion and Tpeak-to-Tend interval were compared between two groups. The paper medical records were used for scoring with San Francisco Syncope Rule (SFSR), Evaluation of Guidelines in SYncope Study (EGSYS) score and …
Computer-aided diagnosis system for characterizing ISUP grade≥2 prostate cancers at multiparametric MRI: A cross-vendor evaluation.
2019
International audience; Purpose: To assess the performance of a computer-aided diagnosis (CADx) system trained at characterizing International Society of Urological Pathology (ISUP) grade >= 2 peripheral zone (PZ) prostate cancers on multiparametric magnetic resonance imaging (mpMRI) examinations from a different institution and acquired on different scanners than those used for the training database.Patients and methods: Preoperative mpMRIs of 74 men (median age, 65.7 years) treated by prostatectomy between 2014 and 2017 were retrospectively selected. One radiologist outlined suspicious lesions and scored them using Prostate Imaging-Reporting and Data System version 2 (PI-RADSv2); their CA…
Features Associated with Recurrence Beyond 5 Years After Nephrectomy and Nephron-Sparing Surgery for Renal Cell Carcinoma: Development and Internal V…
2014
Background: Approximately 10-20% of recurrences in patients treated with nephrectomy for renal cell carcinoma (RCC) develop beyond 5 yr after surgery (late recurrence). Objective: To determine features associated with late recurrence. Design, setting, and participants: A total of 5009 patients from a multicenter database comprising 13 107 RCC patients treated surgically had a minimum recurrence-free survival of 60 mo (median follow-up [FU]: 105 mo [range: 78-135]); at last FU, 4699 were disease free (median FU: 103 mo [range: 78-134]), and 310 patients (6.2%) experienced disease recurrence (median FU: 120 mo [range: 93-149]). Interventions: Patients underwent radical nephrectomy or nephron-…
Towards the potential use of (1)H NMR spectroscopy in urine samples for prostate cancer detection
