Physicians Career Satisfaction: A Tool and Approach in Andalucía, Spain = Satisfacción Profesional de los Médicos: Un instrumento y aproximación en Andalucía, España

Por: Juan Nicolás Peña Sánchez | Fecha: 01/01/2010

Objective: Provide an instrument in Spanish for measuring and studying physicians’ career satisfaction in Andalusia, Spain. Method: It followed two general stages: An instrument adaptation and descriptive cross-sectional study. Factor analysis was performed with 16-item scale. Construct validity was verified through a correlation between the summed 16-items scale and the global item, and internal consistency reliability was estimated with a Cronbach’s alpha. Finally, physicians’ career satisfaction was measured and characteristics related to a higher level of satisfaction were explored through a multivariate logistic regression. Results: An instrument adaption into Spanish was developed. Cronbach’s alpha of the instrument was 0.92. The rate response was 40%. Mean career satisfaction was 4.36(SD=0.76) out of a possible score of 6.Multivariate logistic regression showed that physicians who reported having received non-economic incentives during last year have a level of career satisfaction 3.11(IC=1.19–8.13) times higher than those that have not received, and also that foreign physicians have a level of career satisfaction 7.81(IC=1.40–43.48) times higher than Spanish ones, controlling by personal, professional, work, and incentives factors. Conclusions: This study performed the adaptation and validation of an instrument which measures physicians’ career satisfaction in Andalusia, Spain.The methodology to translate and adapt the instrument was successful, making the method replicable in other languages and countries. The instrument demonstrated acceptable levels of internal consistency reliability and construct validity. It was found that foreign physicians have eight times higher career satisfaction, and physicians that referred having received non-economic incentives during the last year have three times higher career satisfaction.

Physical activity promotion at the local level: municipal sport authorities participation in Colombia = Promoción de la actividad física en el nivel local: participación de las autoridades deportivas municipales en Colombia

Por: Daniela Rozo Salazar | Fecha: 01/01/2014

Physical activity promotion (PAP) has reached policy agendas worldwide due to the social and economic burden that non-communicable diseases have generated. Colombia is one of the countries that have taken the challenge of promoting healthy lifestyles in order to reduce this burden and in addition, take advantage of other benefits that promoting this healthy lifestyle brings. Although some research has been done on the field, no studies related to the local government contribution were found. The local government plays a crucial role in PAP, considering that it has a great influence on the physical and social environment of a city and consequently in the individual behavior of its citizens.Additionally, it has a great responsibility concerning public health, social and economic development and environmental sustainability, aspects that are related to PAP. The present research, aims to provide a general overview on the current state of PAP in the Municipal Sport Authorities (MSAs) of one department of Colombia. In this sense, it is important to highlight that the sport sector has had a major role in PAP in the country and the department. Hence, structured interviews were conducted among heads of the MSAs of the 14 municipalities of the department and development plans were analyzed.Using this data, two main aspects were studied in order to achieve the research aim: the current PAP interventions and the conditions to promote physical activity (PA) in the department. Results indicate that the current PAP interventions have both strengths and weaknesses. Among the most important aspects, it was noticed that PAP in Risaralda has neglected important environmental determinants for PA behavior. PAP has been oriented from an “anthropic” perspective (targeting the individual). However, this seems to have had a positive effect on PA levels in the department. Concerning the conditions to promote PA, there are important findings related to the knowledge and skills of policy-makers and the management process used to develop the interventions. Some of the weaknesses found in the interventions might be related to the conditions to develop them. Recommendations to MSAs and for further research are given.

Phase Ii randomized, double-blind, placebo-controlled study of whole-brain irradiation with concomitant chloroquine for brain metastases

Por: Luis Leonardo; Arce Salinas Rojas Puentes | Fecha: 01/01/2013

Background and purpose: Chloroquine (CLQ), an antimalarial drug, has a lysosomotropic effect associated with increased radiationsensibility, which is mediated by the leakage of hydrolytic enzymes, increased apoptosis, autophagy and increased oxidative stress in vitro. In this phase II study, we evaluated the efficacy and safety of radiosensibilization using CLQ concomitant with 30 Gray (Gy) of whole-brain irradiation (WBI) to treat patients with brain metastases (BM) from solid tumors.Methods: Seventy-three eligible patients were randomized. Thirty-nine patients received WBI (30 Gy in 10 fractions over 2 weeks) concomitant with 150 mg of CLQ for 4 weeks (the CLQ arm). Thirty-four patients received the same schedule of WBI concomitant with a placebo for 4 weeks (the control arm). All the patients were evaluated for quality of life (QoL) using the EORTC Quality of Life (QoL) Questionnaire (EORTC QLQ-C30) (Mexican version) beforebeginning radiotherapy and one month later.Results: The overall response rate (ORR) was 54% for the CLQ arm and 55% for the control arm (p=0.92). The progression-free survival of brain metastases (BMPFS) rates at one year were 83.9% (95% CI 69.4-98.4) for the CLQ arm and 55.1% (95% CI 33.6-77.6) for the control arm. Treatment with CLQ was independently associated with increased BMPFS (RR 0.31,95% CI [0.1-0.9], p=0.046).The only factor that was independently associated with increased overall survival (OS) was the presence of< 4 brain metastases (RR 1.9, 95% CI [1.12-3.3], p=0.017). WBI was associated with improvements in cognitive and emotional function but also with worsened nausea in both patients groups. No differences in QoL or toxicity were found between the study arms.Conclusion: Treatment with CLQ plus WBI improved the control of BM (compared with the control arm) with no increase in toxicity; however, CLQ did not improve the RR or OS. A phase III clinical trial is warranted to confirm these findings.

Performance Evaluation Of The Clinimacs System For The Positive Selection Of CD34+ Cells From Stem Cell Products Factors Affecting CD34+ Cell Recovery

Por: Guillermo Andrés Orjuela Falla | Fecha: 01/01/2009

CD34+ cell dose in the transplanted product is still considered a measure of the engraftment potential in haemopoietic stem cell transplantation (HSCT). CD34+ selected products are characterised by their high purity and depleted T-cells. These characteristics have made them traditionally suitable to decrease the incidence of graft versus host disease, particularly in haploidentical HSCT.The CliniMACS is a state of the art cell sorting system based on magnetic particles conjugated to CD34 antibodies. This study retrospectively evaluated the CliniMACS system performance in terms of CD34+ purity and cell recovery, and T-cell depletion in the selected product. The results were compared against target values fixed by the processing centre, as well as against published data. Factors affecting the CD34+ cell recovery were also investigated and a pilot study was carried out to assess the effect of cryopreservation on the viability of the selected products. In total, 151 procedures were analysed.The mean recovery and purity were 64.82 + 16.19 and 88.0 + 11.0% respectively. The mean T-cell depletion was 4.7021 + 0.5129 logs. Only purity was slightly below the specification (90%), with the lowest values obtained from peripheral blood (PB) collections. Factors affecting the recoveries were the overall age of the product (p=0.001), overnight storage (p=0.002), and the use of a particular tubing set with the instrument (p=0.002).The mean CD34+ viability was not significantly different to the value before cryopreservation (p=0.068). Results from this study were comparable with published data of the CliniMACS system performance. Local investigations regarding the purity of PB products should be performed. For the first time, using a magnetic separation method, factors affecting CD34+ recovery were identified. The significance of the effect of product age and overnight storage on cell recovery, provide a rationale for further prospective studies

Payment method as a predictor of daily distress experienced by physicians

Por: Juan Nicolás; Bermedo Carrasco Peña Sánchez | Fecha: 01/01/2014

Background: Physicians face intrinsic tensions when practicing medicine; therefore, extrinsic factors that could affect distress, such as payment methods, need to be assessed. The study objectives were to: compare levels of distress by payment method, identify factors predicting distress in a two-level regression model, and explore interactions between predictors of distress and payment method.Methods: A cross-sectional study was conducted among physicians in the Saskatoon Health Region, Saskatchewan. Physicians completed a pre-tested questionnaire about their distress. Analysis of variance was used to compare distress levels of physicians paid by fee-for-service (FFS), alternative payment plans (APPs), and blended methods. A mixed linear regression model was built to predict distress with geographical area of practice as the random component. Demographics, workload, complexity of patients, payment method, career satisfaction, and practice profile were the independent variables. The interactions between payment method and predictors of daily distress were evaluated.Results: A total of 382 physicians participated. Response bias was tested and found to be negligible. In the multivariable analysis, payment method was a predictor of distress which interacted with the proportion of complex cases. Lower levels of distress were found among physicians who had more than 75% of patients with complex conditions and were paid by APPs, compared to those paid by FFS and blended methods. Career satisfaction was found to be an important predictor. Nine percent of the outcome variation was explained by geographic area of practice. Conclusions: Payment method is a predictor of distress when adjusting by confounders, interacting with proportion of complex cases. APPs may promote provision of care for patients with complex conditions. Career satisfaction can be considered a protective indicator of distress. Practice environment influences distress experienced by physicians.
