    Dear Editor

    We read with particular interest the recent systematic review and narrative synthesis of clinically assisted hydration in the last days of life [1]. Unsurprisingly, the authors concluded that “there is currently insufficient evidence to draw firm conclusions on the impact of CAH in the last days of life”, which supports the findings of previous reviews [2,3]. We agree with their conclusion, but would like to make some comments on the “quality” / applicability of some of the included (and excluded) studies.

    Our concerns relate to:

    1. Study type – end-of-life care should be evidence based, and the “gold standard” remains the randomised controlled trial (RCT).

    2. Study population – our study [4] excluded patients with dehydration (and with contraindications to CAH), but the Cerchetti et al RCT [5] involved patients with dehydration and renal failure, and the “excluded” Bruera et al RCT [6] specifically involved patients with dehydration. Hence, there is an issue about collating these data, and, importantly, extrapolating these data to the wider population.

    3. Study intervention – our study [4] used a variable volume of fluid, based on the patient’s weight (and in accordance with NICE guidance) [7], but the Cerchetti et al RCT [5], and the Bruera et al RCT [6], both used a fixed volume of fluid (e.g. 1 L / day). The rationale for this volume of fluid is unexplained, but it is much less than recommended for maintenance of hydration...
