Appropriate use of medical imaging in two Spanish public hospitals: a cross-sectional analysis.

ABSTRACT: OBJECTIVES:To determine the appropriateness of medical imaging examinations involving radiation and to estimate the effective radiation dose and costs associated. DESIGN:Cross-sectional retrospective study. SETTING:Two Spanish public tertiary hospitals. PARTICIPANTS:2022 medical imaging tests were extracted from the radiology information system in February and March of 2014. MRI and ultrasound examinations were excluded. PRIMARY AND SECONDARY OUTCOME MEASURES:Five outcomes were set independently by at least two researchers according to four guidelines: (1) appropriate; (2) inappropriate; (3) inappropriate due to repetition, if the timing to carry out next diagnostic tests was incorrect according to guidelines; (4) not adequately justified, if the referral form did not include enough clinical information to allow us to understand the patient's clinical condition; and (5) not included in the guidelines, if the referral could not be matched to a clinical scenario described in the guidelines. We estimated the prevalence of the five categories according to relevant clinical and sociodemographic variables and the effective radiation dose and costs for each category. RESULTS:Approximately half of the imaging tests were deemed as appropriate (967, 47.8%) while one-third (634, 31.4%) were considered inappropriate. 19.6% of the effective dose and 25.2% of the cost were associated with inappropriate tests. Women were less likely than men to have an imaging test classified as appropriate (adjusted OR 0.70,95%?CI 0.57 to 0.86). Imaging tests requested by general practitioners were less likely to be considered appropriate than those requested by central services (adjusted OR 0.60, 95%?CI 0.38 to 0.93). Mammography and CT were more likely to be appropriate than conventional X-rays. CONCLUSION:There was a significant frequency of inappropriateness, which resulted in a high percentage of associated effective radiation dose. Percentage of inappropriateness depends on sociodemographic and clinical characteristics such as sex, age, referral physician and medical imaging test.

Project description:BackgroundAn increasing number of studies on physicians' professionalism have been done since the 2002 publication of Medical Professionalism in the New Millennium: A Physician Charter. The Charter proposed three fundamental principles and ten responsibilities. However, most studies were done in developed countries, and few have been done in China. Additionally, few studies have examined the effect of patient-centered hospital culture (PCHC) on physicians' professionalism. We aimed to investigate physicians' medical professionalism in public hospitals in China, and to assess mediating effect of professional attitudes in the relationship of PCHC with professional behaviours.MethodsSelf-administered questionnaires including professional attitudes (20 items) and behaviours (10 items) survey and PCHC scale (22 items) were given to clinical physicians in five public hospitals, China. The mediating effect of professional attitudes in the relationship of PCHC with professional behaviours was tested.Result232 valid questionnaires were collected. More than 90% (208) respondents agreed with 15 of 20 specific statements on medical professionalism. As for the responsibility of improving quality of care, 54 (23%) respondents disagreed with reporting of incompetent colleagues and as for the responsibility of maintaining professional competence, 49 (21%) disagreed with recertification. More than 185 (83%) respondents reported that they sometimes, usually, or always showed the four positive behaviours on the questionnaire, and 173 (77%) reported that they never showed the six negative behaviours. Mediating effect analysis revealed that two dimensions of PCHC (i.e. value/institution culture and behaviour/material culture) had a significant positive impact on physicians' professional behaviour, and professional attitude played a complete mediation role between them, but another dimension of PCHC (i.e. negative evaluation of hospital) directly affected professional behaviour without influencing professional attitude.ConclusionChinese physicians showed positive professional attitudes and behaviours. Different dimensions of PCHC affected physicians' attitudes and behaviours in different ways.

Project description:There has been a significant rise in global antibiotic use in recent years. Development of resistance has been linked to easy accessibility, lack of regulation of sale, increased tendency to self-medicate and the lack of public knowledge. The increase in antibiotic misuse, including self-medication, has not been well documented in developing countries. Antibiotic use prior to visiting health facilities has been found to be prevalent in developing countries. It has been identified by some studies to increase the likelihood of missed diagnoses and influence the outcome of bacteriological tests. This study is aimed at determining the prevalence of prior antibiotic use through a cross-sectional survey of patients undergoing laboratory tests at two health facilities in Ghana. Face-to-face questionnaires were used to interview 261 individuals chosen by random sampling of patients visiting the bacteriology laboratory of the hospitals within a two-month period. The questionnaire investigated participant demographic characteristics, knowledge about antibiotics and the nature of antibiotic use. Antibiotic property detection bioassay was performed on patient's urine sample using a disk diffusion method to accurately determine antibiotic use within 72 hours. Culture results were used as an index to evaluate the effect of prior antibiotic use on bacteriological tests. Out of a 261 participants enrolled, 19.9% (95% CI, 14.9-24.9) acknowledged using antibiotics prior to their visit to the laboratory during the study period. On the contrary, 31.4% (95% CI, 25.7-37.5) of participants' urine samples were positive for antimicrobial activity. Participants within the age ranges of 20-30, 31-40 and 41-50 years had significantly lower odds of urine antimicrobial activity. Participants who had urine antimicrobial activity were more likely to have no growth on their culture plates than participants who had no urine antimicrobial activity [OR 2.39(1.37-4.18), p = 0.002]. The most commonly used antibiotics were the penicillins, fluoroquinolones and metronidazole. Although, majority of the participant (54.8%) had knowledge of antibiotics, most of them had inadequate information on their proper use. The commonest indications for antibiotic use were aches and pains (30.3%), diarrhoea (43.3%) and urinary tract infections (28.0%). Prior antibiotic use was found to increase the likelihood of obtaining a culture negative result and can affect the outcome of bacteriological tests.

Project description:BackgroundComfort of patients with medical students is important and promotes appropriate clinical reasoning and skills development in the students. There is however limited data in this field in Uganda. In this study, we examined the attitudes and comfort of patients attending care at the medical and obstetrics/gynecology specialties in teaching hospitals of three public universities in Uganda.MethodsWe conducted a cross sectional study among patients attending care at teaching hospitals for three public universities; Makerere University (Mak), Mbarara University of Science and Technology (MUST), and Gulu University (GU). Logistic regression was used to determine the magnitude of associations between independent and dependent variables. Two-sided p < 0.05 was considered statistically significant.ResultsEight hundred fifty-five patients participated in the study. Majority were aged 18 - 39 years (54%, n = 460), female (81%, n = 696) and married (67%, n = 567). Seventy percent (n = 599) of participants could recognize and differentiate medical students from qualified physicians, and had ever interacted with medical students (65%, n = 554) during earlier consultations. Regarding attitudes of patients towards presence of medical students during their consultations, most participants (96%; n = 818) considered involvement of medical students in patients' care as essential ingredient of training of future doctors. Most participants prefer that medical students are trained in the tertiary public hospitals (80%; n = 683) where they attend care. Participants who were single/never married were 68% less likely to recognize and differentiate medical students (aOR = 0.32, 95%CI: 0.22 - 0.53) from other members of the healthcare team as compared with married participants. Participants with university education had 55% lower odds of being comfortable with presence of medical students during consultation compared to those with primary education (aOR = 0.45, 95%CI: 0.21 - 0.94). Participants from MUST teaching hospital had twofold higher odds of being comfortable with presence of medical students compared to participants from Mak teaching hospitals (aOR = 2.01; 95%CI: 1.20 - 3.39).ConclusionPatients are generally comfortable with medical students' involvement in their care; they prefer to seek care in hospitals where medical students are trained so that the students may contribute to their care. Medical students need to introduce themselves appropriately so that all patients can know them as doctors in training; this will promote patients' autonomy and informed decisions.

Project description:ObjectiveTo investigate the determinants of specialty choice among graduating medical students in Spain, a country that entered into a severe, ongoing economic crisis in 2008.SettingSince 2008, the percentage of Spanish medical school graduates electing Family and Community Medicine (FCM) has experienced a reversal after more than a decade of decline.DesignA nationwide cross-sectional survey conducted online in April 2011.ParticipantsWe invited all students in their final year before graduation from each of Spain's 27 public and private medical schools to participate.Main outcome measuresRespondents' preferred specialty in relation to their perceptions of: (1) the probability of obtaining employment; (2) lifestyle and work hours; (3) recognition by patients; (4) prestige among colleagues; (5) opportunity for professional development; (6) annual remuneration and (7) the proportion of the physician's compensation from private practice.Results978 medical students (25% of the nationwide population of students in their final year) participated. Perceived job availability had the largest impact on specialty preference. Each 10% increment in the probability of obtaining employment increased the odds of preferring a specialty by 33.7% (95% CI 27.2% to 40.5%). Job availability was four times as important as compensation from private practice in determining specialty choice (95% CI 1.7 to 6.8). We observed considerable heterogeneity in the influence of lifestyle and work hours, with students who preferred such specialties as Cardiovascular Surgery and Obstetrics and Gynaecology valuing longer rather than shorter workdays.ConclusionsIn the midst of an ongoing economic crisis, job availability has assumed critical importance as a determinant of specialty preference among Spanish medical students. In view of the shortage of practitioners of FCM, public policies that take advantage of the enhanced perceived job availability of FCM may help steer medical school graduates into this specialty.

Project description:BackgroundInformation in health care is rapidly expanding and is updated very regularly, especially with the increasing use of technology in the sector. Due to this, health care providers require timely access to the latest scientific evidence anywhere. Smartphone medical apps are tools to access the latest reputable scientific evidence in the discipline. In addition, smartphone medical apps could lead to improved decision making, reduced numbers of medical errors, and improved communication between hospital medical staff.ObjectiveThe aim of this study was to assess smartphone medical app use and associated factors among physicians working at referral hospitals of the Amhara region, Ethiopia.MethodsAn institution-based cross-sectional study design was conducted among physicians working at 5 referral hospitals in the Amhara region, Ethiopia, from February 5 to May 27, 2019. A simple random sampling method was used to select 423 physicians. A self-administered questionnaire was used to collect the data and analyzed using SPSS, version 21 (IBM Corp). Binary and multivariable logistic regression analysis was performed to assess factors associated with smartphone medical app use among physicians. A value of P<.05, corresponding to a 95% CI, was considered statistically significant. The validity of the questionnaire was determined based on the view of experts and the reliability of it obtained by calculating the value of Cronbach alpha (α=.78).ResultsIn this study, most of the 417 respondents (375, 89.9%) had medical apps installed on their smartphones. Of those 375 respondents, 264 (70.4%) had used medical apps during clinical practice. The medical apps most commonly used by the respondents were UpToDate, Medscape, MedCalc, and Doximity. According to multivariable logistic regression analysis, attitude (adjusted odds ratio [AOR] 1.64, 95% CI 1.05-2.55), internet access (AOR 2.82, 95% CI 1.75-4.54), computer training (AOR 1.71, 95% CI 1.09-2.67), perceived usefulness of the app (AOR 1.64, 95% CI 1.05-2.54), information technology support staff (AOR 2.363, 95% CI 1.5-3.08), and technical skill (AOR 2.52, 95% CI 1.50-4.25) were significantly associated with smartphone medical app use.ConclusionsMost respondents have a smartphone medical app and have used it in clinical practice. Attitude, internet access, computer training, perceived usefulness of the app, information technology support staff, and technical skill are the most notable factors that are associated with smartphone medical app use by physicians.
