ObjectiveTo assess the effect of the duration of fever after the initiation of treatment (FAT) of febrile urinary tract infections (UTI) on the development of permanent renal lesions based on dimercaptosuccinic acid (DMSA) scintigraphy findings. To evaluate the FAT contribution to permanent renal lesion formation in relation to fever before treatment initiation (FBT), the presence of vesicourinary reflux (VUR), age and severity of infection.MethodsThe inpatient records of 148 children (median age: 2.4 months (11 days to 24 months)) with a first episode of UTI during a 3-year period were analysed. DMSA findings, and clinical and laboratory parameters were evaluated.ResultsAmong the study population, 34/148 (22.97%) children had permanent renal lesions on the DMSA scan 6 months after a single episode of UTI. Twenty-three children (15.5%) had mild, 10 (6.7%) had moderate and 1 (0.6%) child had severe lesions on the DMSA. FAT prolongation >/48 hours was associated with older age (p=0.01) and increased absolute neutrophil count (p=0.042). The likelihood of lesions was significantly increased when FAT was ≥48 hours (R2=0.043, p=0.021). On multiple regression analysis, with the addition of FBT>/72 hours (0.022), the presence of VUR (p<0.001), C-reactive protein (p=0.027) and age (p=0.031), the effect of FAT on lesion development disappeared (p=0.15).ConclusionsProlongation of FAT≥48 hours of febrile UTI in children <2 years significantly contributes to the development of permanent renal lesions. However, delay in treatment initiation >/72 hours, the presence of VUR, older age and infection severity seem to be more significant predictors of the development of renal lesions.

Background Research in primary care is necessary to empower its role in health systems and improve population health. Objective The aim of this evaluation study was to assess the experiences of primary care physicians who participated as researchers in a multi-centre, mixed-methodology study on adult vaccination supported by a newly established practice-based research network. Methods Twenty-three physicians participated as researchers, operating in their own practices in 10 different prefectures of Greece. After the completion of the study, they were asked to reflect on their experiences in the research by providing written responses to the questions on the evaluation tool of the study. The open-ended questions were analyzed using thematic content analysis. Results Mean age of the researchers was 42.9 years old (±3.9, min 35, max 49) and 11 (47.8%) were male. Six themes emerged as beneficial for the participating researchers: (i) raised awareness of patients’ needs, (ii) enhancement of clinical practice and services offered, (iii) positive impact on the doctor–patient relationship, (iv) personal satisfaction, (v) enrichment of their curriculum vitae and (vi) improvement of research skills. All researchers were interested in participating in future studies. Conclusion The experience of conducting clinical research on adult vaccination in their own practices within a network was reported to be very rewarding. The benefits gained from their participation could be a valuable tool in promoting research and enhancing the quality of primary health care.

Despite the unequivocal value of vaccination in reducing the global burden of infectious diseases, the anti-vaccination movement thrives. The vast majority of the existing validated tools explore attitudes regarding vaccination in children. The aim of our study was to develop and validate a scale assessing attitudes towards adult immunisation. This national cross-sectional study included adult healthcare users who visited 23 Greek Primary Healthcare Units. The development of the scale was the result of literature review, semi-structured interviews and pilot testing of its preliminary versions. The initial version contained 15 items measuring respondents' attitudes on a 6-point Likert scale. The sample was randomly split into two halves. Exploratory factor analysis, performed in the first sample, was used for the creation of multiitem scales; confirmatory factor analysis was used in the second sample to assess goodness of fit. Moreover, concurrent validity, internal consistency reliability, testretest reliability and ceiling and floor effects were explored. The total sample consisted of 1,571 individuals. Overall 'Cronbach's alpha' (0.821) indicated good internal consistency. The initial exploratory factor analysis resulted in a three-factor model.The subsequent confirmatory factor analysis indicated that an 11-item version of the scale provided the best fit of the model to the data (RMSEA = 0.050, SRMR = 0.053, TLI = 0.937, CFI = 0.955, AIC = 24,999.949). All subscales ('value of adult vaccination', 'safety concerns' and 'perceived barriers') demonstrated strong concurrent associations with participants' attitudes and behaviour regarding vaccination (p < .001). No ceiling or floor effects were noted for any of the subscales (0.13%, 2.61% and 0.51%; 0.13%, 0.57% and 0.45% respectively). The 11-item ATAVAC scale proved to be a reliable and valid tool, suitable for assessing attitudes towards adult vaccination.
