Health needs and perception of health care quality among Asylum Seekers and Refugees in an Italian local health authority: A qualitative study.

Background: Migrants, Asylum Seekers and Refugees (ASRs) represent a vulnerable diversified population with increased risks of developing health problems, and in the hosting countries several barriers often hamper their access to the health services. Gathering information about ASRs' experiences and perceptions of host country health care systems may contribute to improve the quality of health care provided. The aim of this study was to explore the health needs in their bio-psycho-social meaning, and the quality of health care as perceived from the ASRs' perspective. Methods: The qualitative descriptive study was conducted as part of the Project "G-START - testing a governance model of receiving and taking care of the Asylum Seekers and Refugees." Through purposeful and snowball sampling, four Focus Groups conducted in English, Italian and French were carried out between July and August 2019, involving 50 ASRs hosted by four reception centers located on the territory pertaining to an Italian Local Health Authority covering a general population of 500.000 people. The analysis of data was categorical, and was performed using N-Vivo software. Results: The macro-categories emerged were the ASRs' bio-psycho-social health needs, including mental health, sexual and reproductive health, food and nutrition, knowledge of the health care system, need for inclusion; healthcare services access, including barriers before and after the access and the ability of the local health system to respond to existing and evolving demands; strengths of the healthcare and reception systems, and suggestions for improving them in the future. Discussion and conclusions: ASRs present vulnerabilities and specific health needs, and the health care system is not always able to guarantee access or to respond to these needs. Several obstacles have been highlighted, such as linguistic barriers and lack of cultural mediation, bureaucratic and administrative barriers, lack of knowledge of the Italian health care system. An effective reorganization of services driven by a more detailed output analysis of the target population needs, together with the use of cultural mediation, peer to peer education and support, and the training of health professionals are recommended to ensure a more accessible, equitable and effective health care system at local level.

Alinity hq platelet count is not impacted by severe microcytosis.

BACKGROUND: Impedance technology has been shown to overestimate platelet (PLT) count in samples with microcytes, while the optical-fluorescence PLT count (PLT-F) by Sysmex has been suggested to be unaffected by microcytosis. The Abbott Alinity hq analyzer employs multi-dimensional optical PLT counting. Our goal was to assess the accuracy of this technology in microcytic samples. METHODS: Platelet measurements were performed by Alinity hq and the impedance (PLT-I) and PLT-F methods on a Sysmex XN-3000 analyzer on 464 samples. PLT concentration range was 6.56-947 × 109 /L and mean cell volume (MCV) 40.9-123.0 fL. Samples were categorized into normocytic (MCV > 80 fL), microcytic (MCV 65-80 fL), and severely microcytic (MCV < 65 fL) groups. RESULTS: Alinity hq PLT count showed excellent agreement with PLT-F (r = 1.00). Sysmex PLT-I data showed somewhat weaker correlation with both PLT-F and Alinity hq (r = 0.98). Increasing bias between Sysmex PLT-I and PLT-F was seen with decreasing MCV values, with mean bias of 35.2 × 109 /L in severe microcytosis. An inverse relationship was demonstrated between the PLT-I versus PLT-F bias and MCV (p < 0.0001). Consistent mean bias was observed between Alinity hq and PLT-F across all MCV ranges. Mean platelet volume was suppressed or flagged by Sysmex XN in 50% of the samples in the severely microcytic group, and markedly higher red cell distribution width (RDW) was reported compared to Alinity hq (18.1% vs 13.7%, p < 0.0001). CONCLUSION: The Sysmex PLT-I method overestimated the PLT count in samples with severe microcytosis. Alinity hq provided PLT counts and PLT and RBC indices that were not impacted by microcytosis.

Clinical utility of Abbott Alinity hq extended red blood cell parameters in differentiating ß-thalassemia trait and iron deficiency anemia.

INTRODUCTION: The objective of the study was to evaluate the performance of the Abbott Alinity hq advanced multi angle polarized scatter separation (MAPSSTM )-based optical RBC technology, for the differentiation between iron deficiency anemia (IDA) and ß-thalassemia carrier status. METHODS: Four hundred and sixty-four samples were analyzed. 228 were healthy controls, 30 were ß-thalassemia carriers, and 40 were IDA. Receiver operating characteristics analysis evaluated the performance of red cell parameters and mathematical formulas. RESULTS: RBC concentration was the most efficient discriminant (area under the curve; AUC of 0.963, Youden Index of 0.88) followed by red blood cell distribution width in size distribution (AUC of 0.960 and YI of 0.86), and red blood cell distribution width coefficient of variation (AUC of 0.924, and YI of 0.74). The absolute reticulocyte concentration showed good diagnostic efficiency, with AUC of 0.808. Hemoglobin distribution width, the %CV of directly measured cellular hemoglobin concentration, and CHCr, the average hemoglobin concentration of reticulocytes have emerged as novel discriminating parameters, with AUC of 0.749 and 0.785, respectively. The England and Fraser index was the best discriminating mathematical formula based on Youden Index of 0.91. The Ricerca, red blood cell distribution width index, Green and King, and Mentzner Index formulas also showed strong discriminative power. The Shine and Lal index, together with the recent mathematical formula M/H, (ratio of percent microcytic and hypochromic red blood cells) demonstrated moderate performance with AUC of 0.796 and 0.740, respectively. CONCLUSION: Extended red cell analysis delivered by the advanced optical technology on the Alinity hq hematology analyzer has efficient diagnostic utility in the initial discrimination of the two most common microcytic anemias: IDA and ß-thalassemia trait.
