Abstract
Sustainable Development Goals (SDGs) are an urgent call for action adopted by the United Nations to improve health and education, reduce inequality, and spur economic growth. The SDG 3 ...objective of good health and well-being is fundamentally linked to patient safety. Medication safety is a crucial issue in the promotion of health and well-being, and polypharmacy management is a key challenge in medication safety. Inappropriate polypharmacy can increase adverse drug events and health expenditures and reduce patient quality of life. As such, polypharmacy is prominent among older adults with chronic kidney disease. Optimal medication practice requires a high level of evidence-based medicine that integrates both scientific best evidence and patient values and preferences through a shared decision-making process. This article reviews polypharmacy management based on patient engagement and shared decision-making.
Background
Chronic kidney disease (CKD) is known to be associated with cancer mortality. However, no study has considered the well-known cancer prognostic factors, ECOG Performance Status (PS) and ...cancer treatment, as confounding factors. We assessed the independent relationship between CKD and cancer death in stage IV cancer patients.
Methods
In this retrospective observational study, we included stage IV cancer patients diagnosed from 2009 to 2014 in a single center. We collected baseline clinical and laboratory variables, and cancer-specific variables, and assessed the presence of CKD. Our primary outcome was all-cause mortality. The secondary outcome was cancer-specific mortality and site-specific cancer mortality.
Results
Among 961 eligible stage IV cancer patients (median age 69 years, 51.8% male), 150 patients had CKD. During follow-up (median 9.8 months), 638 patients died, of whom 526 patients died from cancer. After adjusting for prognostic variables, including ECOG PS and cancer treatment, all-cause mortality and cancer-specific mortality were significantly higher in CKD patients than in non-CKD patients (HR 1.41, 95% CI 1.13–1.77 and HR 1.43, 95% CI 1.12–1.83, respectively). In patients with breast and kidney and urinary tract cancers, CKD was associated with a significantly increased risk of death (HR 7.01, 95% CI 1.47–33.4 and HR 3.33, 95% CI 1.42–7.78, respectively).
Conclusions
CKD at the time of stage IV cancer diagnosis was associated with all-cause mortality and cancer-specific mortality. Moreover, the association between CKD and cancer-specific death was site specific for breast cancer and kidney and urinary tract cancer.
Chronic kidney disease is an important concern in preventive medicine, but the rate of decline in renal function in healthy population is not well defined. The purpose of this study was to determine ...reference values for the estimated glomerular filtration rate (eGFR) and rate of decline of eGFR in healthy subjects and to evaluate factors associated with this decline using a large cohort in Japan.
Retrospective cross-sectional and longitudinal studies were performed with healthy subjects aged ≥18 years old who received a medical checkup. Reference values for eGFR were obtained using a nonparametric method and those for decline of eGFR were calculated by mixed model analysis. Relationships of eGFR decline rate with baseline variables were examined using a linear least-squares method.
In the cross-sectional study, reference values for eGFR were obtained by gender and age in 72,521 healthy subjects. The mean (±SD) eGFR was 83.7±14.7 ml/min/1.73 m2. In the longitudinal study, reference values for eGFR decline rate were obtained by gender, age, and renal stage in 45,586 healthy subjects. In the same renal stage, there was little difference in the rate of decline regardless of age. The decline in eGFR depended on the renal stage and was strongly related to baseline eGFR, with a faster decline with a higher baseline eGFR and a slower decline with a lower baseline eGFR. The mean (±SD) eGFR decline rate was ‒1.07±0.42 ml/min/1.73 m2/year (‒1.29±0.41%/year) in subjects with a mean eGFR of 81.5±11.6 ml/min/1.73 m2.
The present study clarified for the first time the reference values for the rate of eGFR decline stratified by gender, age, and renal stage in healthy subjects. The rate of eGFR decline depended mainly on baseline eGFR, but not on age, with a slower decline with a lower baseline eGFR.
In the context of worldwide public health, it is very important to promote physical activity among the older people. This study explored the roles and attitudes of senior leaders in promoting ...group-based exercise in their local communities, specifically to determine the level and extent to which to elderly participation was encouraged.
This study conducted semi-structured face-to-face in-depth interviews and employed a subsequent thematic analysis. Participants included 10 club leaders and five sub-leaders who were working at senior clubs in Fujisawa-city, Kanagawa, Japan, from July to September 2018.
Four themes emerged from the interview responses, including "unwavering attitude/conviction in relation to the vision," "leaders must set an example," "a search for balance in delegating responsibilities to members," and "creating and fostering culture and environment of mutual help." Further, each participant outlined several aims, including "achieving healthy longevity for the entire local community," "having older people promote healthy activities among the older people," and "creating a pro-health town."
Findings indicate that policymakers, public health workers, and healthcare providers should recognize the pivotal roles that senior group leaders play in promoting healthy activities for the older people. These efforts should be strongly considered when developing policies and strategies designed to promote overall healthy longevity from a general community perspective.
Renin-angiotensin system (RAS) inhibitors have been increasingly prescribed due to their beneficial effects on end-organ protection. Iatrogenic hyperkalemia is a well-known life-threatening ...complication of RAS inhibitor use in chronic kidney disease (CKD) patients. We hypothesized that CKD patients treated with RAS inhibitors frequently develop hyperkalemia after hospital discharge even if they were normokalemic during their hospitalization because their lifestyles change substantially after discharge. The present study aimed to examine the incidence of newly diagnosed hyperkalemia, the timing of hyperkalemia, and its risk factors in CKD patients treated with RAS inhibitors at the time of hospital discharge.
We retrospectively enrolled patients aged 20 years or older with CKD G3-5 (estimated glomerular filtration rate < 60 mL/min/1.73 m2) and who were treated with RAS inhibitors and discharged from St. Luke's International Hospital between July 2011 and December 2015. Patients who were under maintenance dialysis or had hyperkalemic events before discharge were excluded. Data regarding the patients' age, sex, CKD stage, diabetes mellitus status, malignancy status, combined use of RAS inhibitors, concurrent medication, and hyperkalemic events after discharge were extracted from the hospital database. Our primary outcome was hyperkalemia, defined as serum potassium ≥ 5.5 mEq/L. Multiple logistic regression and Kaplan-Meier analyses were performed to identify the risk factors for and the timing of hyperkalemia, respectively.
Among the 986 patients, 121 (12.3%) developed hyperkalemia after discharge. In the regression analysis, relative to CKD G3a, G3b odds ratio (OR): 1.88, 95% confidence interval 1.20-2.97 and G4-5 (OR: 3.40, 1.99-5.81) were significantly associated with hyperkalemia. The use of RAS inhibitor combinations (OR: 1.92, 1.19-3.10), malignancy status (OR: 2.10, 1.14-3.86), and baseline serum potassium (OR: 1.91, 1.23-2.97) were also significantly associated with hyperkalemia. The Kaplan-Meier analysis showed that hyperkalemia was most frequent during the early period after discharge, particularly within one month.
Hyperkalemia was frequent during the early period after discharge among previously normokalemic CKD patients who were treated with RAS inhibitors. Appropriate follow-up after discharge should be required for these patients, particularly those with advanced CKD or malignancy status, such as hematological malignancy or late-stage malignancy, and those who are treated with multiple RAS inhibitors.
: The number of older adults with cancer is increasing worldwide. The role of nurses in supporting patients' decision-making is expanding, as this process is fraught with complexity and uncertainty ...due to comorbidities, frailty, cognitive decline, etc., in older adults with cancer. The aim of this review was to examine the contemporary roles of oncology nurses in the treatment decision-making process in older adults with cancer.
: A systematic review of PubMed, CINAHL, and PsycINFO databases was conducted in accordance with PRISMA guidelines.
: Of the 3029 articles screened, 56 full texts were assessed for eligibility, and 13 were included in the review. We identified three themes regarding nurses' roles in the decision-making process for older adults with cancer: accurate geriatric assessments, provision of available information, and advocacy. Nurses conduct geriatric assessments to identify geriatric syndromes, provide appropriate information, elicit patient preferences, and communicate efficiently with patients and caregivers, promoting physicians. Time constraints were cited as a barrier to fulfilling nurses' roles.
: The role of nurses is to elicit patients' broader health and social care needs to facilitate patient-centered decision-making, respecting their preferences and values. Further research focusing on the role of nurses that considers diverse cancer types and healthcare systems is needed.
Purpose
To propose a new strategy to prevent communication errors caused by unread radiology reports.
Materials and methods
Medical emergencies were prefixed with triple stars on radiology reports, ...and the attending physician was contacted by telephone. Semi-emergencies (medical issues needing addressing within 2 weeks) were prefixed with double stars. Two weeks later, the duty radiologist would search the double-starred reports, and reviewed relevant patient charts to confirm that the information had been appropriately understood and acted upon. If not, the duty radiologist contacted the referral physician by telephone. One year after implementing this strategy, we retrospectively evaluated 1-year worth of data for all the reports of CT, MRI, nuclear medicine and ultrasonography (April 2018 to March 2019).
Results
Three hundred and twenty-one reports were double starred (0.52% of 62,143 reports, 1.32 reports/day), and transmission of relevant information was incomplete in 23 cases (7.17%). Causes of incomplete transmission were (1) reports not being opened (
n
= 17), (2) relevant information on reports being overlooked (
n
= 5), and (3) the wrong report being opened (
n
= 1). Sixty-five reports contained triple stars (0.10%, 0.27 reports/day).
Conclusion
The proposed strategy may be effective in preventing communication errors in radiology reports with important findings requiring semi-emergency clinical action.
Vadadustat is an oral hypoxia‐inducible factor prolyl hydroxylase inhibitor for the treatment of anemia in patients with chronic kidney disease (CKD). This phase 3, open‐label, 24‐week single‐arm ...study evaluated the efficacy and safety of vadadustat in 42 Japanese CKD patients with anemia undergoing peritoneal dialysis. Patients received oral vadadustat for 24 weeks, initiated at 300 mg/day and doses were adjusted to achieve the target hemoglobin (Hb) range of 11.0‐13.0 g/dL. Least squares mean of average Hb at weeks 20 and 24 was 11.35 g/dL, which was within the target range. The most frequent adverse events were catheter site infections (23.8%), which were not related to vadadustat treatment. Vadadustat was generally well tolerated and effective in controlling Hb levels within the target range, indicating the usefulness of vadadustat for treating anemia in Japanese CKD patients undergoing peritoneal dialysis.
The Japanese Society for Dialysis Therapy (JSDT) guideline committee, chaired by Dr Y. Tsubakihara, presents the Japanese guidelines entitled “Guidelines for Renal Anemia in Chronic Kidney Disease.” ...These guidelines replace the “2004 JSDT Guidelines for Renal Anemia in Chronic Hemodialysis Patients,” and contain new, additional guidelines for peritoneal dialysis (PD), non‐dialysis (ND), and pediatric chronic kidney disease (CKD) patients.
Chapter 1 presents reference values for diagnosing anemia that are based on the most recent epidemiological data from the general Japanese population. In both men and women, hemoglobin (Hb) levels decrease along with an increase in age and the level for diagnosing anemia has been set at <13.5 g/dL in males and <11.5 g/dL in females. However, the guidelines explicitly state that the target Hb level in erythropoiesis stimulating agent (ESA) therapy is different to the anemia reference level. In addition, in defining renal anemia, the guidelines emphasize that the reduced production of erythropoietin (EPO) that is associated with renal disorders is the primary cause of renal anemia, and that renal anemia refers to a condition in which there is no increased production of EPO and serum EPO levels remain within the reference range for healthy individuals without anemia, irrespective of the glomerular filtration rate (GFR). In other words, renal anemia is clearly identified as an “endocrine disease.” It is believed that defining renal anemia in this way will be extremely beneficial for ND patients exhibiting renal anemia despite having a high GFR. We have also emphasized that renal anemia may be treated not only with ESA therapy but also with appropriate iron supplementation and the improvement of anemia associated with chronic disease, which is associated with inflammation, and inadequate dialysis, another major cause of renal anemia.
In Chapter 2, which discusses the target Hb levels in ESA therapy, the guidelines establish different target levels for hemodialysis (HD) patients than for PD and ND patients, for two reasons: (i) In Japanese HD patients, Hb levels following hemodialysis rise considerably above their previous levels because of ultrafiltration‐induced hemoconcentration; and (ii) as noted in the 2004 guidelines, although 10 to 11 g/dL was optimal for long‐term prognosis if the Hb level prior to the hemodialysis session in an HD patient had been established at the target level, it has been reported that, based on data accumulated on Japanese PD and ND patients, in patients without serious cardiovascular disease, higher levels have a cardiac or renal function protective effect, without any safety issues. Accordingly, the guidelines establish a target Hb level in PD and ND patients of 11 g/dL or more, and recommend 13 g/dL as the criterion for dose reduction/withdrawal. However, with the results of, for example, the CHOIR (Correction of Hemoglobin and Outcomes in Renal Insufficiency) study in mind, the guidelines establish an upper limit of 12 g/dL for patients with serious cardiovascular disease or patients for whom the attending physician determines high Hb levels would not be appropriate.
Chapter 3 discusses the criteria for iron supplementation. The guidelines establish reference levels for iron supplementation in Japan that are lower than those established in the Western guidelines. This is because of concerns about long‐term toxicity if the results of short‐term studies conducted by Western manufacturers, in which an ESA cost‐savings effect has been positioned as a primary endpoint, are too readily accepted. In other words, if the serum ferritin is <100 ng/mL and the transferrin saturation rate (TSAT) is <20%, then the criteria for iron supplementation will be met; if only one of these criteria is met, then iron supplementation should be considered unnecessary.
Although there is a dearth of supporting evidence for these criteria, there are patients that have been surviving on hemodialysis in Japan for more than 40 years, and since there are approximately 20 000 patients who have been receiving hemodialysis for more than 20 years, which is a situation that is different from that in many other countries. As there are concerns about adverse reactions due to the overuse of iron preparations as well, we therefore adopted the expert opinion that evidence obtained from studies in which an ESA cost‐savings effect had been positioned as the primary endpoint should not be accepted unquestioningly.
In Chapter 4, which discusses ESA dosing regimens, and Chapter 5, which discusses poor response to ESAs, we gave priority to the usual doses that are listed in the package inserts of the ESAs that can be used in Japan. However, if the maximum dose of darbepoetin alfa that can currently be used in HD and PD patients were to be used, then the majority of poor responders would be rescued.
Blood transfusions are discussed in Chapter 6. Blood transfusions are attributed to the difficulty of managing renal anemia not only in HD patients, but also in end‐stage ND patients who respond poorly to ESAs. It is believed that the number of patients requiring transfusions could be reduced further if there were novel long‐acting ESAs that could be used for ND patients.
Chapter 7 discusses adverse reactions to ESA therapy. Of particular concern is the emergence and exacerbation of hypertension associated with rapid hematopoiesis due to ESA therapy.
The treatment of renal anemia in pediatric CKD patients is discussed in Chapter 8; it is fundamentally the same as that in adults.
