Peritoneal dialysis as the most common form of home dialysis has many advantages in terms of individual freedoms, similar outcomes to haemodialysis, being less costly in some countries, and more scalable than in-centre haemodialysis. Despite this there are many inequities in access at the patient, clinician, health system and geopolitical levels. Poverty, discrimination and lack of support at home are important drivers of inequities at the patient level. At the clinician and health systems level lack of experience in home dialysis, lack of resources and lack of time drive patients towards in-centre dialysis. At the geopolitical level, high costs associated with procurement and distribution of peritoneal dialysis solutions exacerbate inequities in access.SUMMARYThe challenge of reducing global inequities in access to home dialysis in low- and middle-income countries are vast and would require training of the doctors, nurses, families, patients, leaders and community partners. Once this is achieved, dealing with costs and logistics of supplies is crucial to improve and sustain equitable access.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":"4 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review describes how social conditions and humanitarian issues can influence hypertension and kidney disease.RECENT FINDINGSUndoubtedly, social determinants of health (SDoH) are key influencers in the development of many noncommunicable diseases, including hypertension and kidney disease. Healthcare professionals, including public health workers, play a crucial role in addressing these issues. Poverty, low education level, poor nutrition, housing, exposure to environmental hazards, and stress-related disorders are all factors that can be addressed, either directly or indirectly, through improved awareness and access to proper healthcare services. Besides personal factors, national, regional, or global factors cause serious apprehension. Disasters, whether natural or man-made, can lead to significant aftermaths on the healthy person and certainly on kidney disease and hypertensive patients. A Global Overview Report, 2023 turned out to be one of the most violent years since the end of the Cold War. In 2023, 59 state-based conflicts were recorded in 34 countries, the highest number registered since 1946. The wars in Ukraine and Gaza were the primary contributors with a significant impact on the kidney population, especially people living on dialysis and transplantation patients. They also yielded many refugees or displaced persons with ongoing suffering.SUMMARYIt is crucial to recognize that social and humanitarian conditions can quickly exacerbate the health of vulnerable populations, particularly those with noncommunicable diseases like hypertension and chronic kidney disease. These patients, who often require continuous follow-up, especially those on dialysis, are particularly vulnerable during difficult times. Their lives depend on uninterrupted access to dialysis or transplantation medications, making the need for special attention and care more pressing. Further research and advocacy are needed to address these issues and ensure the health and well being of these populations.","PeriodicalId":10960,"journal":{"name":"Current Opinion in Nephrology and Hypertension","volume":"31 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142178118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
