Dialysis access, infections, and hospitalisations in unplanned dialysis start patients: results from the OPTiONS study.

INTRODUCTION: Unplanned dialysis start (UPS) associates with worse clinical outcomes, higher utilisation of healthcare resources, lower chances to select dialysis modality and UPS patients typically commenced in-centre haemodialysis (HD) with central venous catheter (CVC). We evaluated patient outcomes and healthcare utilisation depending on initial dialysis access (CVC or PD catheter) and subsequent pathway of UPS patients. METHODS: In this study patient demographics, access procedures, hospitalisations, and major infectious complications were analysed over 12 months in 270 UPS patients. PD technique survival and impact of switching from HD to PD was examined along with logistic regression to investigate factors predicting AV fistula formation. RESULTS: 72 UPS patients started with PD catheter and 198 with CVC. PD patients were older and more comorbid but had a significantly lower number of access procedures while there was no difference in hospitalisation or major infections. 13/72 initial PD patients switched to HD and 1-year technique survival was 79%. 158/198 patients remained on HD and 73/158 reported permanent access formation. Older age, OR = 0.34 (CI,0.17-0.68) and cardiac failure, OR = 0.31(CI,0.13-0.78), were significant negative predictors of receiving fistula. Younger patients, OR = 0.29 (CI, 0.11-0.79) and those who received AVF, OR = 0.11 (CI,0.03-0.38), had significantly lower odds of death. DISCUSSION: UPS with initial PD was possible in many patients and was associated with lower requirement for access procedures. AVF formation in UPS patients starting on HD was associated with better 1-year survival. Modality switching in UPS patients requires careful clinical management, including clinical practice patterns promoting permanent HD access formation.

Offering Patients Therapy Options in Unplanned Start (OPTiONS): Implementation of an educational program is feasible and effective.

BACKGROUND: Patients with unplanned dialysis start (UPS) have worse clinical outcomes than non-UPS patients, and receive peritoneal dialysis (PD) less frequently. In the OPTiONS study of UPS patients, an educational programme (UPS-EP) aiming at improving care of UPS patients by facilitating care pathways and enabling informed choice of dialysis modality was implemented. We here report on impact of UPS-EP on modality choice and clinical outcomes in UPS patients. METHODS: This non-interventional, prospective, multi-center, observational study included 270 UPS patients from 26 centers in 6 European countries (Austria, Germany, Denmark, France, United Kingdom and Sweden) who prior to inclusion presented acutely, or were being followed by nephrologists but required urgent dialysis commencement by an acutely placed CVC or PD catheter. Effects of UPS-EP on choice and final decision of dialysis therapy and outcomes within 12 months of follow up were analysed. RESULTS: Among 270 UPS patients who had an unplanned start to dialysis, 214 were able to receive and 203 complete UPS-EP while 56 patients - who were older (p = 0.01) and had higher Charlson comorbidity index (CCI; p < 0.01) - did not receive UPS-EP. Among 177 patients who chose dialysis modality after UPS-EP, 103 (58%) chose PD (but only 86% of them received PD) and 74 (42%) chose HD (95% received HD). Logistic regression analysis showed that diabetes 1.88 (1.05 - 3.37) and receiving UPS-EP, OR = 4.74 (CI, 2.05 - 10.98) predicted receipt of PD. Patients choosing PD had higher CCI (p = 0.01), higher prevalence of congestive heart failure (p < 0.01) and myocardial infarction (p = 0.02), and were more likely in-patients (p = 0.02) or referred from primary care (p = 0.02). One year survival did not differ significantly between PD and HD patients. Peritonitis and bacteraemia rates were better than international guideline standards. CONCLUSIONS: UPS-EP predicted patient use of PD but 14% of those choosing PD after UPS-EP still did not receive the modality they preferred. Patient survival in patients choosing and/or receiving PD was similar to HD despite age and comorbidity disadvantages of the PD groups.

Offering Patients Therapy Options in Unplanned Start: Development and Implementation of an Education Program for Unplanned-Start Patients.

Unplanned start of dialysis is still a common and important problem for dialysis units in Europe and across the world: 30%-50% of patients can commence therapy in that way. Such patients are known to experience increased morbidity and mortality, to make greater demands on health care resources, and to be less likely to receive their dialysis modality choice. We therefore aimed to meet the specific needs of unplanned-start patients by developing and implementing an Unplanned Start Educational Programme in dialysis units. The new program--which is intended to effectively influence the clinical pathway for patients and to equip health care professionals with the tools necessary to support and optimize the process of unplanned dialysis start--was created with the support of 5 dialysis units and academic experts in patient education. It involves process mapping of patient flows so as to recognize the key steps in the management of unplanned dialysis. Following its successful development, the Unplanned Start Educational Programme was delivered to patients. To evaluate the effectiveness of the program, an observational study, Offering Patients Therapy Options in Unplanned Start, had the primary outcome of measuring the impact of the education program on dialysis modality choice (peritoneal dialysis or hemodialysis).
