Objectives: to explore how cross-sectional healthcare and treatment is experienced a) by patients with advanced heart failure and multimorbidity and b) by hospital-employed healthcare professionals. Methods: Individual telephone interviews with 18 patients and close relatives were conducted. Furthermore, a focus group session was conducted with four specialised hospitalemployed healthcare professionals. Purposeful sampling was used and interviews were semi-structured. Data were analysed using qualitative inductive content analysis. Results: Three main themes emerged from the interviews with patients and close relatives. These included: 1) A need for improved coordination to ensure continuity of care; 2) a plea for patient-centred care; and 3) recognition of the need to care for close relatives. Analysis of the interviews with hospital-employed healthcare professionals also produced three themes. These concerned: 1) recognition of the role and needs of close relatives; 2) limited resources for and difficulties in meeting these needs; and 3) agreement on the need for patient-centred care. Furthermore, we learned that perceived challenges are rooted in time constraints and the need for an adequate level of medical knowledge of chronic conditions and complex treatment strategies. Conclusions: This study indicates that cross-sectional healthcare and treatment of patients with advanced heart failure and multimorbidity lacked coordination, was insufficiently patient-centred and did not cater for close relatives' needs. The study identifies patient-centredness and coordination of healthcare services targeting patients and close relatives alike as critical to proper care, medical curriculum development and continued medical training courses.

Background and Aims Preventing hyperkalemia - a potentially fatal complication in advanced CKD - by prescribing diets low in K (=limited intake of healthy components such as vegetables, fruits, whole grains and nuts) leads to poor dietary quality. K-restricted unhealthy diets may affect quality of life, patient satisfaction with treatment, achievement of nutritional targets, and increase risk of obstipation, gut dysbiosis and progression of CKD. We designed a feasibility study to test if a low-protein healthy K-rich diet with fruits, vegetables, whole grains and nuts with concomitant use of new potassium binder (SZC) can be safely prescribed to patients with CKD stages 4 and 5 with hyperkalemia. Method A feasibility descriptive single arm open-label interventional trial lasting 6 weeks will enroll 36 CKD patients at the outpatient clinic with: age 18 - 85 years; glomerular filtration rate < 29 ml/min/1.73 m2 and not on dialysis; serum K > 5.1 mmol/L or in previous use of sodium polystyrene sulfonate (SPS) to decrease serum K levels, and who develops hyperkalemia after SPS is ceased. Patients with serum K > 6.5 mmol/L and those likely to start dialysis within 2 months, with inflammatory bowel syndrome or with a history of hypokalemia (<3.0 mmol/L) will not be included. Primary end points will be changes in patient satisfaction with treatment, patient symptom list, and intake of energy and protein before and after the stabilization and healthy diet phase. Secondary outcomes will include changes in quality of life, obstipation and circulating gut microbiota-related uremic toxins. Intervention: In the first 3 weeks, representing stabilization phase, SZC will be prescribed to normalize serum K to 3.5 to 5.0 mml/L, and a diet with energy 25-35 kcal/kg/day and protein 0.6 to 0.8 g/kg/day and with low K content will be prescribed by a renal dietitian. At the end of the first 3 weeks, the patients will be instructed to keep the same content of energy and protein and initiate a healthy diet containing 3700 to 4000 mg/potassium for 3 weeks (healthy diet phase). In order to increase adherence, a food basket containing fruits, vegetables, whole grains, nuts, white meat, fish and eggs in amounts adequate for the patient and the family will be provided. Serum K will be monitored to promote serum K between 3.5 to 5.0 mmol/L and adjustments in the dose of SZC will be performed according to the drug label. Blood measurements, quality of life and intestinal obstipation questionnaires and measurements of nutritional intake will be performed in the beginning and at the end of the stabilization phase and again in the beginning and end of the healthy diet phase. Additionally, during stabilization and healthy diet phases, serum K will be measured every 72 hours until serum K is normalized and after that, once per week. The protocol is registered at www.clinicaltrials.gov (identifier NCT04207203). Results NA Conclusion This interventional feasibility pilot study will test the hypothesis that - with precautions aiming at reducing risk of hyperkalemia - a K-rich healthy diet in patients with CKD stage 4 may improve patient satisfaction with treatment and patient symptoms. Depending on the results, a larger randomized controlled longitudinal trial will be considered to investigate if K-rich diet in CKD stage 4-5 patients is safe and beneficial.
