Exploring the Impact of In Basket Metrics on the Adoption of a New Electronic Health Record System Among Specialists in a Tertiary Hospital in Alberta: Descriptive Study.

BACKGROUND: Health care organizations implement electronic health record (EHR) systems with the expectation of improved patient care and enhanced provider performance. However, while these technologies hold the potential to create improved care and system efficiencies, they can also lead to unintended negative consequences, such as patient safety issues, communication problems, and provider burnout. OBJECTIVE: This study aims to document metrics related to the In Basket communication hub (time in In Basket per day, time in In Basket per appointment, In Basket messages received per day, and turnaround time) of the EHR system implemented by Alberta Health Services, the province-wide health delivery system called Connect Care (Epic Systems). The objective was to identify how a newly implemented EHR system was used, the timing of its use, and the duration of use specifically related to In Basket activities. METHODS: A descriptive study was conducted. Due to the diversity of specialties, the providers were grouped into medical and surgical based on previous similar studies. The participants were further subgrouped based on their self-reported clinical full-time equivalent (FTE ) measure. This resulted in 3 subgroups for analysis: medical FTE <0.5, medical FTE >0.5, and surgical (all of whom reported FTE >0.5). The analysis was limited to outpatient clinical interactions and explicitly excluded inpatient activities. RESULTS: A total of 72 participants from 19 different specialties enrolled in this study. The providers had, on average, 8.31 appointments per day during the reporting periods. The providers received, on average, 21.93 messages per day, and they spent 7.61 minutes on average in the time in In Basket per day metric and 1.84 minutes on average in the time in In Basket per appointment metric. The time for the providers to mark messages as done (turnaround time) was on average 11.45 days during the reporting period. Although the surgical group had, on average, approximately twice as many appointments per scheduled day, they spent considerably less connected time (based on almost all time metrics) than the medical group. However, the surgical group took much longer than the medical group to mark messages as done (turnaround time). CONCLUSIONS: We observed a range of patterns with no consistent direction. There does not seem to be evidence of a "learning curve," which would have shown a consistent reduction in time spent on the system over time due to familiarity and experience. While this study does not show how the included metrics could be used as predictors of providers' satisfaction or feelings of burnout, the use trends could be used to start discussions about future Canadian studies needed in this area.

Impact of Prior Abdominal Procedures on Peritoneal Dialysis Catheter Outcomes: Findings From the North American Peritoneal Dialysis Catheter Registry.

RATIONALE & OBJECTIVE: A history of prior abdominal procedures may influence the likelihood of referral for peritoneal dialysis (PD) catheter insertion. To guide clinical decision making in this population, this study examined the association between prior abdominal procedures and outcomes in patients undergoing PD catheter insertion. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Adults undergoing their first PD catheter insertion between November 1, 2011 and November 1, 2020, at 11 institutions in Canada and the US participating in the International Society for Peritoneal Dialysis (ISPD) North American Catheter Registry. EXPOSURE: Prior abdominal procedure(s), defined as any procedure that enters the peritoneal cavity. OUTCOMES: Primary outcome: time to the first of abandonment of the PD catheter, or interruption/termination of PD. SECONDARY OUTCOMES: rates of emergency room visits, hospitalizations, and procedures. ANALYTICAL APPROACH: Cumulative incidence curves were used to describe the risk over time and an adjusted Cox proportional hazards model was used to estimate the association between the exposure and primary outcome. Models for count data were used to estimate the associations between the exposure and secondary outcomes. RESULTS: A total of 855 patients met the inclusion criteria. Thirty-one percent had a history of a prior abdominal procedure and 20% experienced at least one PD catheter-related complication that led to the primary outcome. Prior abdominal procedures were not associated with an increased risk of the primary outcome [Adjusted HR 1.12 (95% CI 0.68-1.84)]. Upper abdominal procedures were associated with a higher adjusted hazard of the primary outcome, but there was no dose-response relationship concerning the number of procedures. There was no association between prior abdominal procedures and other secondary outcomes. LIMITATIONS: Observational study and cohort limited to sample of patients felt to be potential candidates for PD catheter insertion. CONCLUSION: A history of prior abdominal procedure(s) does not appear to influence catheter outcomes following PD catheter insertion. Such a history should not be a contraindication to peritoneal dialysis.

The Association of Intra-Abdominal Adhesions with Peritoneal Dialysis Catheter-Related Complications.

BACKGROUND: This study investigated the association of intra-abdominal adhesions with the risk of peritoneal dialysis (PD) catheter complications. METHODS: Individuals undergoing laparoscopic PD catheter insertion were prospectively enrolled from eight centers in Canada and the United States. Patients were grouped based on the presence of adhesions observed during catheter insertion. The primary outcome was the composite of PD never starting, termination of PD, or the need for an invasive procedure caused by flow restriction or abdominal pain. RESULTS: Seven hundred and fifty-eight individuals were enrolled, of whom 201 (27%) had adhesions during laparoscopic PD catheter insertion. The risk of the primary outcome occurred in 35 (17%) in the adhesion group compared with 58 (10%) in the no adhesion group (adjusted HR, 1.64; 95% confidence interval [CI], 1.05 to 2.55) within 6 months of insertion. Lower abdominal or pelvic adhesions had an adjusted HR of 1.80 (95% CI, 1.09 to 2.98) compared with the no adhesion group. Invasive procedures were required in 26 (13%) and 47 (8%) of the adhesion and no adhesion groups, respectively (unadjusted HR, 1.60: 95% CI, 1.04 to 2.47) within 6 months of insertion. The adjusted odds ratio for adhesions for women was 1.65 (95% CI, 1.12 to 2.41), for body mass index per 5 kg/m 2 was 1.16 (95% CI, 1.003 to 1.34), and for prior abdominal surgery was 8.34 (95% CI, 5.5 to 12.34). Common abnormalities found during invasive procedures included PD catheter tip migration, occlusion of the lumen with fibrin, omental wrapping, adherence to the bowel, and the development of new adhesions. CONCLUSIONS: People with intra-abdominal adhesions undergoing PD catheter insertion were at higher risk for abdominal pain or flow restriction preventing PD from starting, PD termination, or requiring an invasive procedure. However, most patients, with or without adhesions, did not experience complications, and most complications did not lead to the termination of PD therapy.

Patient Training and Patient Safety in Home Hemodialysis.

The success of a home hemodialysis program depends largely on a patient safety framework and the risk tolerance of a home dialysis program. Dialysis treatments require operators to perform dozens of steps repeatedly and reliably in a complex procedure. For home hemodialysis, those operators are patients themselves or their care partners, so attention to safety and risk mitigation is front of mind. While newer, smaller, and more user-friendly dialysis machines designed explicitly for home use are slowly entering the marketplace, teaching patients to perform their own treatments in an unsupervised setting hundreds of times remains a foundational programmatic obligation regardless of machine. Just how safe is home hemodialysis? How does patient training affect this safety? There is a surprising lack of literature surrounding these questions. No consensus exists among home hemodialysis programs regarding optimized training schedules or methods, with each program adopting its own approach on the basis of local experience. Furthermore, there are little available data on the safety of home hemodialysis as compared with conventional in-center hemodialysis. This review will outline considerations for training patients on home hemodialysis, discuss the safety of home hemodialysis with an emphasis on the risk of serious and life-threatening adverse effects, and address the methods by which adverse events are monitored and prevented.

Predictors of Care Gaps in Home Dialysis: The Home Dialysis Virtual Ward Study.

BACKGROUND: Home dialysis patients may be at an increased risk of adverse events after transitional states. The home dialysis virtual ward (HDVW) trial was conducted in Canadian dialysis centers and aimed to evaluate potential care gaps and patient satisfaction during the HDVW. METHODS: The HDVW was a multicenter single-arm trial including peritoneal dialysis and home hemodialysis patients after 4 different events (hospital discharge, medical procedure, antibiotics, completion of training). Telephone-led interviews using a standardized assessment tool were performed over a 2-week period to assess a patient's care and adjust treatment as required. Upon completion, patients were surveyed to evaluate their perceived impact on domains of care using a rating scale; 1 not satisfied to 10 completely satisfied. RESULTS: The HDVW trial included 193 patients with a median number of potential care gaps/interventions of 1 (0-2) per patient. Patients admitted to the HDVW after hospital discharge were at a higher risk of potential gaps in care (OR 2.16, 95% CI 1.29-3.62), while longer dialysis vintage was -associated with a lower number of gaps/interventions (OR 0.97 per year, 95% CI 0.95-0.98). A total of 105/193 (54%) patients completed satisfaction surveys. Patients were highly satisfied with the HDVW (median rating scale score 8, IQR 2) and felt it had a positive impact (rating scale score ≥7) on their overall health, understanding of treatment and access to a nephrologist. CONCLUSION: The HDVW was effective at identifying several potential care gaps, and patients were satisfied across several domains of care. This intervention may be valuable in supporting home dialysis patients during care transitions.

Acute Kidney Injury in Pregnant Patient With Pancreas-Kidney Transplant Caused by Abdominal Compartment Syndrome: A Case Presentation, Review of Literature, and Proposal of Diagnostic Approach.

RATIONALE: With increasing number of complex medical patients with renal transplant who get pregnant, clinicians need to be aware of abdominal compartment syndrome which may masquerade as acute renal allograft injury in pregnancy. PRESENTING CONCERNS OF THE PATIENT: A 34-year-old nulliparous Caucasian female with end-stage renal disease (ESRD) due to type 1 diabetes mellitus who received a simultaneous pancreas-kidney transplant (SPK) in 2006 and then after rejection of renal allograft another, kidney-only allograft from a donation after circulatory death became pregnant in May 2013 with dichorionic, diamniotic twins without reproductive technology, and during pregnancy, she developed two episodes of acute injury to the renal allograft. DIAGNOSES: End-stage renal disease secondary to type I diabetes, acute renal allograft injury, tacrolimus toxicity, abdominal pain. INTERVENTIONS INCLUDING PREVENTION AND LIFESTYLE: She received intravenous hydration, medications contributing to renal failure were held, and pain and nauseas were controlled appropriately. Abdominal compartment syndrome was managed by maintaining intravascular pressure and optimizing regional and systemic vascular perfusion by appropriate fluid balance, evacuating intraluminal contents by decompressing gastrointestinal system, and improving abdominal wall compliance by using appropriate analgesics, sedation, and patient positioning. OUTCOMES: With advancing pregnancy, the patient developed progressive abdominal pain, nausea, leg edema, and rising creatinine that were not responsive to ongoing therapies and required delivery via Cesarean section at 31 weeks of gestational age. LESSONS LEARNED: In the era of increasing number of pregnant renal transplant patients with multiple medical issues, we need organized approach to diagnosis of acute renal allograft injury in pregnancy and we need to consider abdominal compartment syndrome as one of the causes.

JUSTIFICATION: Le nombre croissant de grossesses chez les greffées d'un rein aux prises avec des problèmes de santé complexes oblige les cliniciens à connaître le syndrome du compartiment abdominal; un trouble qui, pendant la grossesse, peut contribuer à une insuffisance rénale aiguë du greffon. PRÉSENTATION DU CAS: Une femme nullipare de 34 ans d'origine caucasienne et atteinte d'insuffisance rénale terminale (IRT) consécutive à un diabète de type 1. La patiente avait subi une première greffe simultanée rein-pancréas en 2006 puis, pour cause de rejet, une deuxième transplantation d'un rein seulement, lequel provenait d'un donneur décédé d'un problème circulatoire. La patiente est tombée enceinte de jumeaux diachroniques et diamniotiques en mai 2013 sans procréation assistée. La grossesse a été ponctuée de deux épisodes d'insuffisance rénale aiguë du greffon. DIAGNOSTIC: IRT consécutive à un diabète de type 1, insuffisance rénale aiguë du greffon, toxicité du tacrolimus, douleurs abdominales. INTERVENTIONS PRÉVENTION ET HABITUDES DE VIE: La patiente a été réhydratée par intraveineuse, les douleurs abdominales et les nausées ont été soulagées, et les médicaments contribuant à l'insuffisance rénale ont été temporairement cessés. Le syndrome du compartiment abdominal a été traité en maintenant la pression intravasculaire et en optimisant la perfusion vasculaire locale et systémique par un équilibre hydrique approprié, en évacuant le contenu intraluminal par décompression du système gastro-intestinal, et en améliorant la compliance de la paroi abdominale par l'administration d'analgésiques, par la sédation et par le positionnement de la patiente. ISSUE: Avec la progression de la grossesse, les symptômes de douleurs abdominales, nausées, œdème aux membres inférieurs et augmentation de la créatinine ayant cessé de répondre aux traitements, la patiente a dû accoucher par césarienne à 31 semaines. ENSEIGNEMENTS TIRÉS: Le nombre croissant de femmes enceintes greffées d'un rein et atteintes de problèmes de santé complexes plaide pour une approche concertée dans le diagnostic de l'insuffisance aiguë du greffon pendant la grossesse. Le syndrome du compartiment abdominal doit être envisagé comme l'une des causes de l'insuffisance rénale aiguë en grossesse.

Impact of Ramadan fasting on kidney function and related outcomes in patients with chronic kidney disease: a systematic review protocol.

INTRODUCTION: Fasting during the month of Ramadan is a significant Islamic religious practice that involves abstinence from food, drink and medication from dawn to dusk. As just under a quarter of the world's population identifies as Muslim, the effect of fasting on chronic conditions, such as chronic kidney disease (CKD) is a topic of broad relevance. To date, the information in this area has been mixed, with many limitations of previous studies. This study aims to synthesise the evidence of the effect of Ramadan fasting on changes on kidney function, risk factors, episodes of acute kidney injury and impact on the quality of life in patients with CKD or kidney transplant. METHODS AND ANALYSIS: A systematic review of the literature will be conducted, using electronic databases such as MEDLINE, Embase, Global Health, CINAHL and Scopus. Original research and grey literature on the effect of Ramadan fasting in adult patients with CKD or renal transplantation will be included. Two reviewers will independently screen articles for inclusion in the review and independently assess the methodology of included studies using a customised checklist. Mean difference or risk ratio will be reported for continuous or dichotomous outcomes and results will be pooled using a random-effects model where heterogeneity is reasonable. If possible, subgroups (CKD status, setting, season and risk of bias) will be analysed for effect modification with fasting and the outcomes of interest. Risk of bias will be assessed using the Downs and Black checklist. ETHICS AND DISSEMINATION: The results will be disseminated using a multifaceted approach to engage all stakeholders (patients, practitioners and community leaders). Research ethics board approval is not required as this is a systematic review of previously published research. PROSPERO REGISTRATION NUMBER: CRD42018088973.

Prospective monitoring of after-hours nursing and technologist support calls to a regional Canadian home hemodialysis program.

INTRODUCTION: Increasing renal care providers offer home hemodialysis (HD) as a modality choice. There is considerable variation in the provision of after-hours on-call support for self-dialyzing patients and no literature describing the utility of this service. In this prospective, observational study we sought to monitor and classify the number and nature of interactions between home patients and our on-call nurses and technologists, and enumerate the number of adverse events averted by the availability of on-call staff. METHODS: Our home HD unit provided 24-hour on-call patient support and during a 4-month period in 2012, we prospectively monitored all patient calls to this service. The nature of the calls was logged as nursing-related vs. technical. Call outcomes were classified according to whether patients were able to initiate/resume their treatments or whether additional interventions were required. FINDINGS: During this period, our program cared for 58 home HD patients. Nurses fielded 172 calls and dealt with 239 issues. One hundred nine (46%) were clinical issues including 5 (2%) of a serious nature involving potential harm; 67 (28%) related to machine setup or alarms, 36 (15%) required a technologist to resolve, and 27 (11%) were deemed non-urgent. One hundred six issues were directed to technologists in 99 calls. Issues pertained to machine malfunction (45 calls-43%), machine set-up and alarms (25 calls-24%), or the water system (24 calls-23%). Only 12 calls (11.3%) were not of a technical nature. Nursing and technologist support allowed patients to initiate or continue their treatment 75% and 71% of the time, respectively. DISCUSSION: Home HD on-call services provide patients support to successfully continue their dialysis treatments by troubleshooting clinical and technical aspects of dialysis and by averting potential adverse events.

Technique Failure in a Multicenter Canadian Home Hemodialysis Cohort.

RATIONALE & OBJECTIVE: Increasing uptake of home hemodialysis (HD) has led to interest in characteristics that predict discontinuation of home HD therapy for reasons other than death or transplantation. Recent reports of practice pattern variability led to the hypothesis that there are patient- and center-specific factors that influence these discontinuations. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Incident home HD patients at 7 centers in Canada between 2000 and 2010. PREDICTOR: Treatment center, case-mix, and process-of-care variables. OUTCOMES: Technique failure (defined as discontinuation of home HD therapy for any reason other than training failure, death, or transplantation) and mortality. ANALYTICAL APPROACH: Regression modeling of technique failure using Cox proportional hazard models adjusting for treatment center and modifiable and nonmodifiable patient-level variables, censored for death and transplantation. RESULTS: The cohort consisted of 579 patients. Mean age was 49.9±14.1 years, 74% were of European ancestry, median dialysis vintage was 1.9 (IQR, 0.6-5.2) years, and 68% used an arteriovenous access. Mean duration of dialysis was 31.2±12.6 hours per week. Unadjusted 1- and 2-year technique survival and overall survival were 90% and 83% and 94% and 87%, respectively. Treating center was a strong predictor of technique failure and mortality, with HRs ranging from 0.37 to 5.11 for technique failure (1 of 6 centers with P<0.05 relative to the reference) and 0.17 to 8.73 for mortality (3 of 6 centers with P<0.05 relative to the reference). With baseline adjustment for center, only older age and more than 3 treatments per week remained significant predictors of technique failure, while no individual-level variables remained as significant predictors of survival. LIMITATIONS: Limited statistical power. CONCLUSIONS: Home HD treating centers may influence technique failure and patient mortality independent of case-mix. The relationship between processes of care and patient outcomes requires further investigation.

Quality Assurance Audit of Technique Failure and 90-Day Mortality after Program Discharge in a Canadian Home Hemodialysis Program.

BACKGROUND AND OBJECTIVES: Little is known about patients exiting home hemodialysis. We sought to characterize the reasons, clinical characteristics, and pre-exit health care team interactions of patients on home hemodialysis who died or underwent modality conversion (negative disposition) compared with prevalent patients and those who were transplanted (positive disposition). DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted an audit of all consecutive patients incident to home hemodialysis from January of 2010 to December of 2014 as part of ongoing quality assurance. Records were reviewed for the 6 months before exit, and vital statistics were assessed up to 90 days postexit. RESULTS: Ninety-four patients completed training; 25 (27%) received a transplant, 11 (12%) died, and 23 (25%) were transferred to in-center hemodialysis. Compared with the positive disposition group, patients in the negative disposition group had a longer mean dialysis vintage (3.15 [SD=4.98] versus 1.06 [SD=1.16] years; P=0.003) and were performing conventional versus a more intensive hemodialysis prescription (23 of 34 versus 23 of 60; P<0.01). In the 6 months before exit, the negative disposition group had significantly more in-center respite dialysis sessions, had more and longer hospitalizations, and required more on-call care team support in terms of phone calls and drop-in visits (each P<0.05). The most common reason for modality conversion was medical instability in 15 of 23 (65%) followed by caregiver or care partner burnout in three of 23 (13%) each. The 90-day mortality among patients undergoing modality conversion was 26%. CONCLUSIONS: Over a 6-year period, approximately one third of patients exited the program due to death or modality conversion. Patients who die or transfer to another modality have significantly higher health care resource utilization (e.g., hospitalization, respite treatments, nursing time, etc.).

Estimating patient-borne water and electricity costs in home hemodialysis: a simulation.

BACKGROUND: Home hemodialysis is associated with lower costs to the health care system compared with conventional facility-based hemodialysis because of lower staffing and overhead costs, and by transferring the treatment cost of utilities (water and power) to the patient. The purpose of this study was to determine the utility costs of home hemodialysis and create a formula such that patients and renal programs can estimate the annual patient-borne costs involved with this type of treatment. METHODS: Seven common combinations of treatment duration and dialysate flows were replicated 5 times using various combinations of home hemodialysis and reverse osmosis machines. Real-time utility (electricity and water) consumption was monitored during these simulations. A generic formula was developed to allow patients and programs to calculate a more precise estimate of utility costs based on individual combinations of dialysis intensity, frequency and utility costs unique to any patient. RESULTS: Using typical 2014 utility costs for Edmonton, the most expensive prescription was for nocturnal home hemodialysis (8 h at 300 mL/min, 6 d/wk), which resulted in a utility cost of $1269 per year; the least expensive prescription was for conventional home hemodialysis (4 h at 500 mL/min, 3 d/wk), which cost $420 per year. Water consumption makes up most of this expense, with electricity accounting for only 12% of the cost. INTERPRETATION: We show that a substantial cost burden is transferred to the patient on home hemodialysis, which would otherwise be borne by the renal program.

In-Center Nocturnal Hemodialysis Versus Conventional Hemodialysis: A Systematic Review of the Evidence.

BACKGROUND: Owing to its longer treatment duration-up to 8 hours per dialysis treatment-in-center thrice-weekly nocturnal hemodialysis (HD) is receiving greater attention. To better understand the evidence for in-center nocturnal HD, we sought to systematically review the literature to determine the effects of in-center nocturnal HD versus conventional HD on clinically relevant outcomes. STUDY DESIGN: We searched MEDLINE, Embase, Evidence-Based Medicine Reviews (EBMR), Web of Science, and Scopus from the earliest date in the database to November 2016. SETTING & POPULATION: Adults receiving in-center nocturnal HD compared with those receiving conventional HD. SELECTION CRITERIA FOR STUDIES: All quasi-experimental and observational studies were considered; randomized trials were sought but not found. PREDICTOR: Nocturnal vs conventional in-center HD. OUTCOMES: Indexes of blood pressure and left ventricular hypertrophy, markers of anemia, measures of bone mineral metabolism, nutrition, quality of life, sleep quality, episodes of intradialytic hypotension, hospitalization, and mortality. RESULTS: Of 2,086 identified citations, 21 met the inclusion criteria, comprising a total of 1,165 in-center nocturnal HD patients and 15,865 conventional HD patients. Although there was substantial heterogeneity in reporting of outcomes, we pooled data for measures of blood pressure, anemia, and mineral metabolism. Though heterogeneity was generally high, in-center nocturnal HD was associated with improved systolic blood pressure (-3.18 [95% CI, -5.58 to -0.78) mm Hg, increased hemoglobin levels (0.53 [95% CI, 0.11-0.94] g/dL), and lower serum phosphate levels (-0.97 [95% CI, -1.48 to -0.46] mg/dL). LIMITATIONS: No randomized trials have been conducted to address the clinical effects of in-center nocturnal HD. The quality of the observational literature contributing to the results of this review was generally poor to moderate. Confounded outcomes are a significant concern. Publication bias and outcome reporting bias remain possibilities. CONCLUSIONS: Relative to conventional HD, in-center nocturnal HD was associated with improvements in several clinically relevant outcomes. Other benefits may not have been detected due to small sample sizes of included studies; no prespecified outcome was worse with in-center nocturnal HD.

Clinical safety and performance of VIVIA: a novel home hemodialysis system.

Background: The VIVIA Hemodialysis System (Baxter Healthcare Corporation, Deerfield, IL, USA) was designed for patient use at home to reduce the burden of treatment and improve patient safety. It has unique features including extended use of the dialyzer and blood set through in situ hot-water disinfection between treatments; generation of on-line infusible-quality dialysate for automated priming, rinseback and hemodynamic support during hypotension and a fully integrated access disconnect sensor. Methods: The safety and performance of VIVIA were assessed in two clinical studies. A first-in-man study was a prospective, single-arm study that involved 22 prevalent hemodialysis (HD) patients who were treated for ∼4 h, four times a week, for 10 weeks. A second clinical study was a prospective, single-arm study (6-8 h of dialysis treatment at night three times a week) that involved 17 prevalent patients treated for 6 weeks. Results: There were 1114 treatments from the two studies (first-in-man study, 816; extended duration study, 298). Adverse events (AEs) were similar in the two studies to those expected for prevalent HD patients. No deaths and no device-related serious AEs occurred. Adequacy of dialysis ( Kt / V ) urea in both clinical trials was well above the clinical guidelines. VIVIA performed ultrafiltration accurately as prescribed in the two studies. The majority of patients achieved 10 or more uses of the dialyzer. Endotoxin levels and bacterial dialysate sampling met infusible-quality dialysate standards. Conclusion: These results confirm the safety and expected performance of VIVIA.

Why take the chance? A qualitative grounded theory study of nocturnal haemodialysis recipients who decline kidney transplantation.

OBJECTIVE: The objective of this study was to examine the factors that influence decision-making to forgo transplantation in favour of remaining on nocturnal haemodialysis (NHD). DESIGN: A grounded theory approach using in-depth telephone interviewing was used. SETTING: Participants were identified from 2 tertiary care renal programmes in Canada. PARTICIPANTS: The study participants were otherwise eligible patients with end-stage renal disease who have opted to remain off of the transplant list. A total of 7 eligible participants were interviewed. 5 were male. The mean age was 46 years. ANALYSIS: A constant comparative method of analysis was used to identify a core category and factors influencing the decision-making process. RESULTS: In this grounded theory study of people receiving NHD who refused kidney transplantation, the core category of 'why take a chance when things are going well?' was identified, along with 4 factors that influenced the decision including 'negative past experience', 'feeling well on NHD', 'gaining autonomy' and 'responsibility'. CONCLUSIONS: This study provides insight into patients' thought processes surrounding an important treatment decision. Such insights might help the renal team to better understand, and thereby respect, patient choice in a patient-centred care paradigm. Findings may also be useful in the development of education programmes addressing the specific concerns of this population of patients.

Peritoneal Dialysis-Related Peritonitis Due to Abiotrophia defectiva: A Case Report.

BACKGROUND: Abiotrophia defectiva is a fastidious aerobic gram-positive bacterium which is part of the normal flora of the human oral cavity. It is an unusual cause of peritoneal dialysis-related peritonitis. CASE PRESENTATION: We present a case of a man in his fifties with end-stage renal failure secondary to polycystic kidney disease who presented with a cloudy peritoneal fluid effluent and a cell count of 35 620 × 106 cells/L with 90% polymorphonuclear cells. The fluid was cultured per unit protocol, and the organism was identified as Abiotrophia defectiva. Post-peritonitis dialysis technique review revealed frequent lapses in the use of facemask and hand washing during cycler connection and disconnection. The patient responded well to vancomycin; however, he subsequently developed ultrafiltration failure and symptoms of fluid overload and uremia and was transferred to home hemodialysis. CONCLUSIONS: Abiotrophia defectiva is an unusual cause of peritoneal dialysis-related peritonitis. The organism is a normal commensal of the oral cavity and may cause peritonitis in patients with nonadherence to dialysis technique. In our case, the infection was followed by peritoneal membrane failure and transfer to hemodialysis. It remains to be seen if peritonitis with Abiotrophia defectiva heralds a worse outcome.

MISE EN CONTEXTE: Une des causes inhabituelles de péritonites en situation de dialyse péritonéale est attribuée à Abiotrophia defectiva, une bactérie à Gram positif aérobie et exigeante qui fait partie de la flore normale de la cavité buccale. PRÉSENTATION DU CAS: Nous présentons le cas d'un patient âgé de 51 ans atteint d'insuffisance rénale terminale à la suite d'une maladie polykystique des reins (MPR). Le patient présentait des effluents de liquide péritonéal troubles dont le compte cellulaire évalué à 35 620 × 106 cellules/L comportait 90 % de cellules polymorphonucléaires. Le fluide a été recueilli selon le protocole de l'unité de dialyse et le microorganisme responsable de l'infection identifié comme étant Abiotrophia defectiva. L'examen de la technique de dialyse après la péritonite a révélé de fréquentes lacunes dans le port du masque ou dans le lavage des mains au moment du branchement ou du débranchement du cycleur. Le patient a bien répondu au traitement antibiotique par la vancomycine, mais a tout de même connu une défaillance de microfiltration et développé des symptômes de surcharge liquidienne ainsi que d'urémie à la suite de sa péritonite, ce qui a nécessité son transfert sur hémodialyse à domicile. CONCLUSIONS: La bactérie Abiotrophia defectiva est une cause inhabituelle de péritonite reliée à la dialyse péritonéale. Ce microorganisme est un commensal normal de la cavité buccale et peut causer des péritonites chez les patients qui ne suivent pas les consignes strictes de cette technique de dialyse. Dans le cas présenté, l'infection a été suivie d'une défaillance de la membrane péritonéale qui a nécessité le transfert du patient sur hémodialyse. Il reste à démontrer si les cas de péritonites par Abiotrophia defectiva s'avèrent annonciateurs d'un pronostic aussi pessimiste.

Patient safety in home hemodialysis: quality assurance and serious adverse events in the home setting.

Interest in home hemodialysis (HD) is high because of the reported benefits and its excellent safety record. However, the potential for serious adverse events (AEs) exists when patients perform HD in their homes without supervision. We review the epidemiology of dialysis-related emergencies during home HD, and present a conceptual and practical framework for the prevention and management of serious AEs for those patients performing home HD. In addition, we describe a formal monitored and iterative quality assurance program, and make suggestions for the future development of safety strategies to mitigate the risk of AEs in home HD.

Delivering home hemodialysis: is there still a role for real-time treatment monitoring?

Remote real-time treatment monitoring for home hemodialysis (HHD) was driven by concerns over patient safety in the early era of HHD. However, decades of clinical experience supported by objective data suggest that HHD is very safe and that remote monitoring is unlikely to avert serious adverse events. As a result, such remote monitoring is not routinely offered in the current era and is generally considered an unnecessary expense. However, a one-size-fits-all approach to abandon remote monitoring may overlook potential opportunities: to improve the clinical care of patients dialyzing at home; and to give patients the confidence to perform HHD in an unsupervised setting.

Buttonhole versus rope-ladder cannulation of arteriovenous fistulas for hemodialysis: a systematic review.

BACKGROUND: The buttonhole technique is an alternative method of cannulating the arteriovenous fistula (AVF) in hemodialysis (HD), frequently used for home HD patients. However, the balance of risks and benefits of the buttonhole compared with the rope-ladder technique is uncertain. STUDY DESIGN: A systematic review of randomized trials and observational studies (case reports, case series, studies without a control group, non-English studies, and abstracts were excluded). SETTING & POPULATION: HD patients (both in-center conventional HD and home HD) using an AVF for vascular access. SELECTION CRITERIA FOR STUDIES: We searched MEDLINE, EMBASE, EBM Reviews, and CINAHL from the earliest date in the databases to March 2014 for studies comparing clinical outcomes of the buttonhole versus rope-ladder technique. INTERVENTION: Buttonhole versus rope-ladder cannulation technique. OUTCOMES: The primary outcomes of interest were patient-reported cannulation pain and rates of AVF-related local and systemic infections. Secondary outcomes included access survival, intervention, hospitalization, and mortality, as well as hematoma and aneurysm formation, time to hemostasis, and all-cause hospitalization and mortality. RESULTS: Of 1,044 identified citations, 23 studies were selected for inclusion. There was equivocal evidence with respect to cannulation pain: pooled observational studies yielded a statistical reduction in pain with buttonhole cannulation (standardized mean difference, -0.76 [95%CI, -1.38 to -0.15] standard deviations), but no difference in cannulation pain was found among randomized controlled trials (standardized mean difference, 0.34 [95%CI, -0.76 to 1.43] standard deviations). Buttonhole, as compared to rope-ladder, technique appeared to be associated with increased risk of local and systemic infections. LIMITATIONS: Overall poor quality and substantial heterogeneity among studies precluded pooling of most outcomes. CONCLUSIONS: Evidence does not support the preferential use of buttonhole over rope-ladder cannulation in either facility-based conventional HD or home HD. This does not preclude buttonhole cannulation as being appropriate for some patients with difficult-to-access AVFs.
