Assessment of Global Kidney Health Care Status.

Importance: Kidney disease is a substantial worldwide clinical and public health problem, but information about available care is limited. Objective: To collect information on the current state of readiness, capacity, and competence for the delivery of kidney care across countries and regions of the world. Design, Setting, and Participants: Questionnaire survey administered from May to September 2016 by the International Society of Nephrology (ISN) to 130 ISN-affiliated countries with sampling of key stakeholders (national nephrology society leadership, policy makers, and patient organization representatives) identified by the country and regional nephrology leadership through the ISN. Main Outcomes and Measures: Core areas of country capacity and response for kidney care. Results: Responses were received from 125 of 130 countries (96%), including 289 of 337 individuals (85.8%, with a median of 2 respondents [interquartile range, 1-3]), representing an estimated 93% (6.8 billion) of the world's population of 7.3 billion. There was wide variation in country readiness, capacity, and response in terms of service delivery, financing, workforce, information systems, and leadership and governance. Overall, 119 (95%), 95 (76%), and 94 (75%) countries had facilities for hemodialysis, peritoneal dialysis, and kidney transplantation, respectively. In contrast, 33 (94%), 16 (45%), and 12 (34%) countries in Africa had facilities for hemodialysis, peritoneal dialysis, and kidney transplantation, respectively. For chronic kidney disease (CKD) monitoring in primary care, serum creatinine with estimated glomerular filtration rate and proteinuria measurements were reported as always available in only 21 (18%) and 9 (8%) countries, respectively. Hemodialysis, peritoneal dialysis, and transplantation services were funded publicly and free at the point of care delivery in 50 (42%), 48 (51%), and 46 (49%) countries, respectively. The number of nephrologists was variable and was low (<10 per million population) in Africa, the Middle East, South Asia, and Oceania and South East Asia (OSEA) regions. Health information system (renal registry) availability was limited, particularly for acute kidney injury (8 countries [7%]) and nondialysis CKD (9 countries [8%]). International acute kidney injury and CKD guidelines were reportedly accessible in 52 (45%) and 62 (52%) countries, respectively. There was relatively low capacity for clinical studies in developing nations. Conclusions and Relevance: This survey demonstrated significant interregional and intraregional variability in the current capacity for kidney care across the world, including important gaps in services and workforce. Assuming the responses accurately reflect the status of kidney care in the respondent countries, the findings may be useful to inform efforts to improve the quality of kidney care worldwide.

Is clomiphene citrate stair-step protocol a good alternative to gonadotrophins in clomiphene-resistant PCO patients? Prospective study.

AIM: To compare the efficacy and safety of the clomiphene citrate (CC) stair-step protocol with standard gonadotrophin (follicle-stimulating hormone) treatment in clomiphene-resistant polycystic ovary syndrome (PCOS) patients. The study was a prospective cohort study in a tertiary infertility center in Abu Dhabi, United Arab Emirates (UAE). METHODS: The subjects consisted of 100 PCOS CC-resistant patients who attended between January 2014 and January 2015. Fifty received CC again but in accordance with the stair-step protocol, and the other 50 received the standard gonadotrophin treatment used in the center in which the study was conducted. The primary outcome measure was dominant follicle achievement; the secondary outcome measures were (i) clinical pregnancy rate; (ii) time to ovulation measured from treatment initiation to sonographic confirmation of a dominant follicle in days; and (iii) adverse effect occurrence. RESULTS: There was no difference between the two treatment modalities concerning the ability to achieve a dominant follicle or the clinical pregnancy rate. The time to ovulation was significantly shorter with the CC stair-step protocol than with gonadotrophin treatment. Ovarian hyperstimulation syndrome and ovarian cyst formation were more likely to occur with gonadotrophin treatment. CONCLUSION: Clomiphene citrate stair-step protocol can be offered to PCOS CC-resistant patients as an alternative to gonadotrophin therapy with similar efficacy.

Prediction of recurrent ectopic pregnancy: A five-year follow-up cohort study.

OBJECTIVE: To evaluate the value of different clinical risk factors in the prediction of recurrent ectopic pregnancies (REP). STUDY DESIGN: This cohort study was carried out at a tertiary-care maternity hospital in Saudi Arabia, between January 2010 and June 2017. All women with a primary ectopic pregnancy (EP) were consecutively recruited, thoroughly assessed and followed up for a minimum duration of five-years (5.6 ±â€¯0.61 years) to diagnose the nature and location of the subsequent pregnancies. The primary outcome measure was the occurrence of REP, while the secondary outcomes included intrauterine pregnancy, the pregnancy of unknown location and infertility rates. RESULTS: A total of 272 women with a primary ectopic pregnancy (EP) were initially recruited, 217 women were included in the final analysis, among them 41 (18.9%) women had REP. Univariate analysis showed that women who subsequently developed REP had more prevalent prior miscarriages, evacuation of retained products of conception (ERPC), pelvic inflammatory disease (PID) and consanguinity, they also had lower hemoglobin levels at the time of primary EP, and lower prevalence of surgical treatment. Among the 143 surgically treated cases, salpingectomy, when compared to salpingostomy, and laparoscopy, when compared with laparotomy, were found to be associated with a lower risk of REP [RR = 0.32 (95% CI, 0.13-0.77) and 0.40 (95% CI, 0.18-0.86) respectively]. The occurrence of a subsequent delivery at any time after the primary EP was protective against REP [RR = 0.39 (95% CI, 0.22-0.68)], this protection is increased by almost nine folds if this delivery occurred at the descendant pregnancy [RR = 0.04 (95% CI, 0.01-0.17)]. Multivariable binary logistic regression revealed that prior PID, treatment modality and presenting hemoglobin level were independent predictors of REP. Receiver operating characteristic (ROC) curve was plotted using the predicted probability values derived from the multivariable binary logistic regression model, the area under the ROC curve was 0.792 (95% CI, 0.732-0.844). CONCLUSION: Careful consideration of primary ectopic pregnancy data is a valuable tool to predict the potential risk of recurrence in the future.

Guidelines, policies, and barriers to kidney care: findings from a global survey.

An international survey led by the International Society of Nephrology in 2016 assessed the current capacity of kidney care worldwide. To better understand how governance and leadership guide kidney care, items pertinent to government priority, advocacy, and guidelines, among others, were examined. Of the 116 responding countries, 36% (n = 42) reported CKD as a government health care priority, which was associated with having an advocacy group (χ2 = 11.57; P = 0.001). Nearly one-half (42%; 49 of 116) of countries reported an advocacy group for CKD, compared with only 19% (21 of 112) for AKI. Over one-half (59%; 68 of 116) of countries had a noncommunicable disease strategy. Similarly, 44% (48 of 109), 55% (57 of 104), and 47% (47 of 101) of countries had a strategy for nondialysis CKD, chronic dialysis, and kidney transplantation, respectively. Nearly one-half (49%; 57 of 116) reported a strategy for AKI. Most countries (79%; 92 of 116) had access to CKD guidelines and just over one-half (53%; 61 of 116) reported guidelines for AKI. Awareness and adoption of guidelines were low among nonnephrologist physicians. Identified barriers to kidney care were factors related to patients, such as knowledge and attitude (91%; 100 of 110), physicians (84%; 92 of 110), and geography (74%; 81 of 110). Specific to renal replacement therapy, patients and geography were similarly identified as a barrier in 78% (90 of 116) and 71% (82 of 116) of countries, respectively, with the addition of nephrologists (72%; 83 of 116) and the health care system (73%; 85 of 116). These findings inform how kidney care is currently governed globally. Ensuring that guidelines are feasible and distributed appropriately is important to enhancing their adoption, particularly in primary care. Furthermore, increasing advocacy and government priority, especially for AKI, may increase awareness and strategies to better guide kidney care.

Global overview of health systems oversight and financing for kidney care.

Reliable governance and health financing are critical to the abilities of health systems in different countries to sustainably meet the health needs of their peoples, including those with kidney disease. A comprehensive understanding of existing systems and infrastructure is therefore necessary to globally identify gaps in kidney care and prioritize areas for improvement. This multinational, cross-sectional survey, conducted by the ISN as part of the Global Kidney Health Atlas, examined the oversight, financing, and perceived quality of infrastructure for kidney care across the world. Overall, 125 countries, comprising 93% of the world's population, responded to the entire survey, with 122 countries responding to questions pertaining to this domain. National oversight of kidney care was most common in high-income countries while individual hospital oversight was most common in low-income countries. Parts of Africa and the Middle East appeared to have no organized oversight system. The proportion of countries in which health care system coverage for people with kidney disease was publicly funded and free varied for AKI (56%), nondialysis chronic kidney disease (40%), dialysis (63%), and kidney transplantation (57%), but was much less common in lower income countries, particularly Africa and Southeast Asia, which relied more heavily on private funding with out-of-pocket expenses for patients. Early detection and management of kidney disease were least likely to be covered by funding models. The perceived quality of health infrastructure supporting AKI and chronic kidney disease care was rated poor to extremely poor in none of the high-income countries but was rated poor to extremely poor in over 40% of low-income countries, particularly Africa. This study demonstrated significant gaps in oversight, funding, and infrastructure supporting health services caring for patients with kidney disease, especially in low- and middle-income countries.

Global coverage of health information systems for kidney disease: availability, challenges, and opportunities for development.

Development and planning of health care services requires robust health information systems to define the burden of disease, inform policy development, and identify opportunities to improve service provision. The global coverage of kidney disease health information systems has not been well reported, despite their potential to enhance care. As part of the Global Kidney Health Atlas, a cross-sectional survey conducted by the International Society of Nephrology, data were collected from 117 United Nations member states on the coverage and scope of kidney disease health information systems and surveillance practices. Dialysis and transplant registries were more common in high-income countries. Few countries reported having nondialysis chronic kidney disease and acute kidney injury registries. Although 62% of countries overall could estimate their prevalence of chronic kidney disease, less than 24% of low-income countries had access to the same data. Almost all countries offered chronic kidney disease testing to patients with diabetes and hypertension, but few to high-risk ethnic groups. Two-thirds of countries were unable to determine their burden of acute kidney injury. Given the substantial heterogeneity in the availability of health information systems, especially in low-income countries and across nondialysis chronic kidney disease and acute kidney injury, a global framework for prioritizing development of these systems in areas of greatest need is warranted.

Global access of patients with kidney disease to health technologies and medications: findings from the Global Kidney Health Atlas project.

Access to essential medications and health products is critical to effective management of kidney disease. Using data from the ISN Global Kidney Health Atlas multinational cross-sectional survey, global access of patients with kidney disease to essential medications and health products was examined. Overall, 125 countries participated, with 118 countries, composing 91.5% of the world's population, providing data on this domain. Most countries were unable to access eGFR and albuminuria in their primary care settings. Only one-third of low-income countries (LICs) were able to measure serum creatinine and none were able to access eGFR or quantify proteinuria. The ability to monitor diabetes mellitus through serum glucose and glycated hemoglobin measurements was suboptimal. Pathology services were rarely available in tertiary care in LICs (12%) and lower middle-income countries (45%). While acute and chronic hemodialysis services were available in almost all countries, acute and chronic peritoneal dialysis services were rarely available in LICs (18% and 29%, respectively). Kidney transplantation was available in 79% of countries overall and in 12% of LICs. While over one-half of all countries publicly funded RRT and kidney medications with or without copayment, this was less common in LICs and lower middle-income countries. In conclusion, this study demonstrated significant gaps in services for kidney care and funding that were most apparent in LICs and lower middle-income countries.
