RESUMO
Introduction: Case managers can guide caregivers during their search for care for relatives with neurocognitive disorders. The present study aimed to evaluate the effects of this procedure on caregiver burden and quality of life. Methods: Family caregivers searching for care at a memory clinic before the first consultation were provided written information and they provided verbal consent to participate in this pre-post intervention study. Intervention was a structured pre-consultation phone call interview given by the case manager to inform and organize individualize pathway of care. The mini-Zarit Burden Interview and the EuroQol five-dimensional questionnaire quality of life scores were recorded by an independent assessor before the intervention and 1 month thereafter. An expectation questionnaire was also completed during the assessments. The pre and post scores were compared using the Wilcoxon signed-rank test. Results: In total, 45 participants were enrolled and 35 were assessed twice. There was no significant change in the total mini-Zarit Burden Interview score; however, the levels of stress due to caring and meeting familial responsibilities (p = 0.025), and the fear of what the future holds for the participants' relative (p = 0.01) was lower at 1 month. The need for information about the pathways of care decreased, but no change in support satisfaction was observed. Quality of life was good and did not change. Conclusions: During the pre-consultation intervention, the case manager may fulfill several needs of caregivers, particularly to obtain personalized information, which should be implemented in memory clinics.
RESUMO
BACKGROUND: The recent spread of positron emission tomography-computed tomography (PET/CT) poses extremity dosimetry challenges. The question arose whether the radiation dose measured by the ring thermoluminescent dosimeter usually worn on the proximal phalanx (P1) of the index finger measures doses that are representative of the true doses received by the upper extremities of the operators. A prospective individual dosimetry study was performed in which the personal equivalent dose Hp (0.07) received during a specific 2-[(18)F]fluoro-2-deoxy-D-glucose ((18)F-FDG) manual dose-dispensing procedure was measured in a paired design by two operational personal electronic dosimeters fitted on the palm side of the index finger, namely in the P1 and distal phalanx (P3) positions. The study participants were ten nuclear medicine technologists working in two nuclear medicine departments. The personal equivalent radiation doses received by the palm side of the proximal phalanx of the index finger [Hp (0.07)P1] and that received by the distal phalanx [Hp (0.07)P3] were compared. RESULTS: The median Hp (0.07)P3/Hp (0.07)P1 ratio per participant varied between 1.0 and 2.5 (based on 23 to 31 measurements per participant). The 271 paired measurements revealed a crude Hp (0.07)P3/Hp (0.07)P1 ratio of 1.67, significantly different from 1 (p = 0.0004, 95 % CI [1.35-2.07]). When adjusted on participant's gender and mother vial activity, the ratio was similar (1.53, p = 0.003, 95 % CI [1.22-1.92]). CONCLUSIONS: The study demonstrated a significant disparity that may exist between the radiation doses measured in the P1 and P3 positions of operators during (18)F-FDG manipulation. These findings emphasize the importance of performing workplace dosimetry studies adapted to each radiopharmaceutical and manipulation thereof, aiming to guarantee optimal workers' dosimetry monitoring schemes.
