背景技术为了促进成像资源规划和实现联合国2030年可持续发展目标的关键卫生目标,需要国家一级成像人员的准确数据。这些数据目前是有限的。目标本研究旨在分析数字趋势,地理分布,2002年至2019年南非(SA)诊断成像人员的人口统计学。方法回顾性分析2002-2019年南非卫生职业委员会(HPCSA)影像学人员数据库。计算了国家和每个专业群体的人员总数和每百万人的人员(放射科,放射诊断技师,和超声医师)按日历年,省,和人口概况。人口数据由统计局提供。结果成像人员总数,每百万人的数量,全国人口增长了283%(3,095对8,753),119%(68对149/106),和29%(45.45对58.77/106),分别。在整个审查期间,放射诊断技师占员工总数的80%以上,增长185%(2,540对7,242)。超声波专家,最小的队列,记录最高(49对503;906%)和放射科医生(506对1,007;99%)最低的比例增长。尽管放射科医生显示出持续的男性优势,男性比例从82%下降到69%,而女性的比例从18%上升到31%。女性放射科医生(14%)的平均年增长率是男性(4%)的三倍以上。放射诊断技师显示女性占主导地位,但比例从90%下降到83%,而男性从10%增加到17%。超声波检查者显示出压倒性的女性优势(94%对92%)。男性放射诊断技师(21%)的平均年增长率是女性(9%)的两倍多。2002年,48%(n=1,475)的成像人员被确定为白人,15%(n=467)被确定为非洲黑人。到2019年,白人和黑人分别为36%(n=3,122)和35%(n=3,045),分别。西开普省(WCP)每百万人的成像人员总数最高(165对233/106),林波波最低(12对54/106)。然而,Limpopo记录的成像人员比例增长最高/106人(368%),WCP最低(41%)。因此,资源最好和资源最少的省份之间的差异从2002年的14:1下降到2019年的4:1。结论在审查期间,SA成像劳动力已显示出实质性的扩张和转变,并承担了更公平的分配。
Background To facilitate imaging resource planning and address key health targets of the United Nations (UN) 2030 Sustainable Development Goals, accurate data are required on imaging personnel at the country level. Such data are currently limited. Objectives This study aims to analyze trends in the number, geographical distribution, and demographics of South African (SA) diagnostic imaging personnel between 2002 and 2019. Method A retrospective analysis of the Health Professions Council of South Africa (HPCSA) database of imaging personnel from 2002 to 2019 was done. The total number of personnel and personnel per million people were calculated for the country and for each professional group (radiologist, diagnostic radiographer, and sonographer) by calendar year, province, and demographic profile. Population data were provided by Statistics SA. Results The total imaging personnel, number per million people, and national population increased by 283% (3,095 versus 8,753), 119% (68 versus 149/106), and 29% (45.45 versus 58.77/106), respectively. Diagnostic radiographers constituted more than 80% of the workforce throughout the review period, increasing by 185% (2,540 versus 7,242). Sonographers, the smallest cohort, recorded the highest (49 versus 503; 906%) and radiologists (506 versus 1,007; 99%) the lowest proportional growth. Although radiologists showed persistent male predominance, the male proportion decreased from 82% to 69%, while that of females increased from 18% to 31%. The average annual percentage increase in female radiologists (14%) was more than three times that of males (4%). Diagnostic radiographers showed female predominance, but the proportion decreased from 90% to 83%, while that of males increased from 10% to 17%. Sonographers showed overwhelming female predominance (94% versus 92%). The average annual percentage increase in male diagnostic radiographers (21%) was more than double that of females (9%). In 2002, 48% (n = 1,475) of imaging personnel identified as White, and 15% (n = 467) identified as Black African. By 2019, those identifying as White and Black African were 36% (n = 3,122) and 35% (n = 3,045), respectively. The Western Cape Province (WCP) maintained the highest overall number of imaging personnel per million people (165 versus 233/106) and Limpopo the lowest (12 versus 54/106). However, Limpopo recorded the highest proportional growth in imaging personnel/106 people (368%) and the WCP the lowest (41%). The differential between the best- and least-resourced provinces thus decreased from 14:1 in 2002 to 4:1 in 2019. Conclusion In the review period, the SA imaging workforce has shown substantial expansion and transformation and has assumed a more equitable distribution.
