This paper estimates point prevalence of renal replacement therapy (RRT) utilization within population strata defined by geography and deprivation in south and mid Wales. It investigates spatial accessibility of main and satellite renal units by comparing population and patient numbers within bands of travel time.
Prevalence study based on patient registers.
From a list of patient and renal unit locations, geocoded at the level of unit postcodes, and electoral division-level denominator population data, we calculated RRT point prevalence for the 16 unitary authorities in the study area, fifths of small area deprivation, and three bands of travel time from the nearest main renal unit and any (main or satellite) unit.
Overall point prevalence was 633 per million population (pmp) and this varied from 256 to 780 pmp across unitary authorities. RRT prevalence was lower in more deprived areas. Sixty-nine percent of the population and 73% of patients lived within 30 min of a main renal unit. Eighty-four percent of the population and 88% of patients lived within 30 min of a main or satellite renal unit.
The provision of satellite renal units has significantly improved spatial accessibility of RRT services. However, a substantial proportion of the population remains geographically distant from renal units. This has important implications for planning of future provision of RRT, given the inverse relationship between RRT acceptance and travel time, and the impact on quality of life of patients who travel frequently to renal units.
本文估计了威尔士南部和中部按地理区域和贫困程度划分的人群阶层中肾脏替代治疗(RRT)的使用点患病率。通过比较不同出行时间范围内的人口和患者数量,研究了主要肾脏单位和卫星肾脏单位的空间可达性。
基于患者登记册的患病率研究。
根据患者和肾脏单位位置列表(在单位邮政编码级别进行地理编码)以及选区级别分母人口数据,我们计算了研究区域内16个单一管理区、小区域贫困程度五等分以及距最近主要肾脏单位和任何(主要或卫星)单位三个出行时间范围内的RRT点患病率。
总体点患病率为每百万人口633例(pmp),各单一管理区的患病率在256至780 pmp之间。在贫困程度较高的地区,RRT患病率较低。69%的人口和73%的患者居住在距主要肾脏单位30分钟路程内。84%的人口和88%的患者居住在距主要或卫星肾脏单位30分钟路程内。
卫星肾脏单位的设立显著提高了RRT服务的空间可达性。然而,相当一部分人口在地理上距离肾脏单位仍然较远。鉴于RRT接受率与出行时间之间的反比关系以及频繁前往肾脏单位对患者生活质量的影响,这对未来RRT服务的规划具有重要意义。
