Background: People with end-stage kidney disease have high prevalence of frailty. The mobility component of integrated Palliative Outcome Scale (iPOS) may be helpful to monitor functional status and inform management strategies. Aim: This study aimed to evaluate the mobility component of iPOS for uptake and change over 12 months and its influence on referrals. Methods: Between 2018-19, a retrospective clinical audit was conducted at a tertiary dialysis unit. We quantified the number of people who completed iPOS from each year and assessed longitudinal changes of paired data. In the 2019 group, we compared socio-demographic, clinical profile and referrals between people who completed (c-iPOS) and did not complete iPOS (non-iPOS). Results: Despite similar completion rates in 2018 [74/114 (65%)] and 2019 [75/118 (64%)], only 35 people had paired data, 26 did not have data at the second time-point, 6 changed centre and 6 passed-away. Paired 'mobility' data showed a trend towards worsening (p<0.06). In 2019, 75 people completed and 43 did not complete iPOS. The groups demonstrated similar socio-demographic (i.e., female, age, non-English speaking) and clinical characteristics (e.g., number of medications). iPOS completion did not influence exercise referral (c-iPOS: 1%, non-iPOS: 0%). Conclusion: This study showed stable completion rates that appeared independent of sociodemographic and/or clinical status, however completion did not influence exercise referral. The lack of significance may be attributed to low sensitivity in blunt metrics. Future research may consider supplementing high iPOS scores with an objective frailty assessment to evaluate status and inform referrals. Summary: This audit aimed to evaluate the utility of iPOS to inform frailty management in people with end-stage kidney disease. Despite stable annual uptake, iPOS did not influence exercise referral. Objective assessments may be useful to supplement iPOS and inform referrals.
