Barriers to goals of care discussions with seriously ill hospitalized patients and their families: a multicenter survey of clinicians.

IMPORTANCE: Seriously ill hospitalized patients have identified communication and decision making about goals of care as high priorities for quality improvement in end-of-life care. Interventions to improve care are more likely to succeed if tailored to existing barriers. OBJECTIVE: To determine, from the perspective of hospital-based clinicians, (1) barriers impeding communication and decision making about goals of care with seriously ill hospitalized patients and their families and (2) their own willingness and the acceptability for other clinicians to engage in this process. DESIGN, SETTING, AND PARTICIPANTS: Multicenter survey of medical teaching units of nurses, internal medicine residents, and staff physicians from participating units at 13 university-based hospitals from 5 Canadian provinces. MAIN OUTCOMES AND MEASURES: Importance of 21 barriers to goals of care discussions rated on a 7-point scale (1 = extremely unimportant; 7 = extremely important). RESULTS: Between September 2012 and March 2013, questionnaires were returned by 1256 of 1617 eligible clinicians, for an overall response rate of 77.7% (512 of 646 nurses [79.3%], 484 of 634 residents [76.3%], 260 of 337 staff physicians [77.2%]). The following family member-related and patient-related factors were consistently identified by all 3 clinician groups as the most important barriers to goals of care discussions: family members' or patients' difficulty accepting a poor prognosis (mean [SD] score, 5.8 [1.2] and 5.6 [1.3], respectively), family members' or patients' difficulty understanding the limitations and complications of life-sustaining treatments (5.8 [1.2] for both groups), disagreement among family members about goals of care (5.8 [1.2]), and patients' incapacity to make goals of care decisions (5.6 [1.2]). Clinicians perceived their own skills and system factors as less important barriers. Participants viewed it as acceptable for all clinician groups to engage in goals of care discussions-including a role for advance practice nurses, nurses, and social workers to initiate goals of care discussions and be a decision coach. CONCLUSIONS AND RELEVANCE: Hospital-based clinicians perceive family member-related and patient-related factors as the most important barriers to goals of care discussions. All health care professionals were viewed as playing important roles in addressing goals of care. These findings can inform the design of future interventions to improve communication and decision making about goals of care.

Programmatic variation in home hemodialysis in Canada: results from a nationwide survey of practice patterns.

BACKGROUND: Over 40% of patients with end stage renal disease in the United States were treated with home hemodialysis (HHD) in the early 1970's. However, this number declined rapidly over the ensuing decades so that the overwhelming majority of patients were treated in-centre 3 times per week on a 3-4 hour schedule. Poor outcomes for patients treated in this fashion led to a renewed interest in home hemodialysis, with more intensive dialysis schedules including short daily (SDHD) and nocturnal (NHD). The relative infancy of these treatment schedules means that there is a paucity of data on 'how to do it'. OBJECTIVE: We undertook a systematic survey of home hemodialysis programs in Canada to describe current practice patterns. DESIGN: Development and deployment of a qualitative survey instrument. SETTING: Community and academic HHD programs in Canada. PARTICIPANTS: Physicians, nurses and technologists. MEASUREMENTS: Programmatic approaches to patient selection, delivery of dialysis, human resources available, and follow up. METHODS: We developed the survey instrument in three phases. A focus group of Canadian nephrologists with expertise in NHD or SDHD discussed the scope the study and wrote questions on 11 domains. Three nephrologists familiar with all aspects of HHD delivery reviewed this for content validity, followed by further feedback from the whole group. Multidisciplinary teams at three sites pretested the survey and further suggestions were incorporated. In July 2010 we distributed the survey electronically to all renal programs known to offer HHD according to the Canadian Organ Replacement Registry. We compiled the survey results using qualitative and quantitative methods, as appropriate. RESULTS: Of the academic and community programs that were invited to participate, 80% and 63%, respectively, completed the survey. We observed wide variation in programmatic approaches to patient recruitment, human resources, equipment, water, vascular access, patient training, dialysis prescription, home requirements, patient follow up, medications, and the approach to non-adherent patients. LIMITATIONS: Cross-sectional survey, unable to link variation to outcomes. Competition for patients between HHD and home peritoneal dialysis means that case mix for HHD may also vary between centres. CONCLUSIONS: There is wide variation between programs in all domains of HHD delivery in Canada. We plan further study of the extent to which differences in approach are related to outcomes.

PROBLÉMATIQUE: Au début des années 70, plus de 40% des patients en insuffisance rénale terminale aux États-Unis étaient traités par hémodialyse à domicile (HDD). Cette proportion a décliné rapidement au cours des décennies suivantes, de sorte que le mode de suppléance pour la majorité des patients est maintenant l'hémodialyse 3 fois par semaine à raison de 3 à 4 heures par séance. Les mauvais résultats obtenus avec cette méthode ont renouvelé l'intérêt pour l'HDD, notamment pour les dialyses intensives incluant la dialyse quotidienne courte (DQC) et l'hémodialyse nocturne (HDN). Étant donné leur nouveauté, il y a peu de données sur les façons de faire avec ces modes de suppléance. OBJECTIF: Afin de décrire les pratiques actuelles, nous avons réalisé un questionnaire systématique auprès des programmes d'HDD au Canada. DESIGN: Développement et déploiement d'un outil qualitatif. CADRE: Programmes d'HDD académiques et communautaires au Canada. PARTICIPANTS: Médecins, infirmières et technologues. VARIABLES MESURÉES: Approches pour la sélection des patients, le mode de suppléance, les ressources humaines disponibles et le mode de suivi pour chaque programme. MÉTHODOLOGIE: Nous avons développé un outil en trois phases. Un groupe de discussion composé de néphrologues canadiens ayant une expertise en DQC ou HDN ont échangé sur le contenu de l'étude et ont rédigé des questions sur 11 domaines. Trois néphrologues familiers avec tous les aspects de l'HDD ont révisé la validité des questions, puis ont demandé un nouvel avis à tout le groupe de discussion. Des équipes multidisciplinaires provenant de trois sites ont ensuite évalué le questionnaire et ont apporté des suggestions. En juillet 2010, le questionnaire a été distribué électroniquement à tous les programmes qui offrent l'HDD d'après le Registre canadien des insuffisances et des transplantations d'organes. Les résultats ont été compilés au moyen de méthodes qualitatives ou quantitatives, le cas échéant. RÉSULTATS: 80% des centres académiques et 63% des centres communautaires invités ont répondu au questionnaire. Nous avons observé des variations importantes entre les programmes quant au recrutement des patients, aux ressources humaines, à l'équipement, à l'eau, aux accès vasculaires, à l'entraînement des patients, à la prescription de dialyse, aux exigences du domicile, au suivi des patients, à la médication et à l'approche face aux patients non-adhérents. LIMITATIONS: Étude transversale, incapacité d'associer les variations aux issues cliniques. La compétition entre l'HDD et la dialyse péritonéale pour le recrutement des patients entraîne peut-être une variabilité entre les centres dans la composition des groupes de patients en HDD. CONCLUSIONS: Il y a de grandes variations entre les programmes dans tous les domaines concernant l'HDD au Canada. Nous planifions d'étudier dans le futur jusqu'à quel point ces différences sont reliées aux issues cliniques.

Exacerbation of underlying hypothyroidism caused by proteinuria and induction of urinary thyroxine loss: case report and subsequent investigation.

OBJECTIVE: To describe a patient with excess urinary thyroxine (T4) excretion and worsening of preexisting hypothyroidism in the setting of nephrotic syndrome and to determine whether excess urinary T4 excretion is present in other patients with proteinuria. METHODS: We present data regarding the patient's initial presentation, diagnostic studies, and course of her illness. We suspected urinary T4 loss to be the cause of her presentation and analyzed her urine sample for total T4. We also analyzed differences in urinary T4 excretion in 22 patients with proteinuria and 16 control patients without proteinuria. Relevant medical literature is reviewed. RESULTS: A 44-year-old woman presented with a 3-month history of increasing fluid retention, weight gain, and fatigue. She had long-standing hypothyroidism on a stable levothyroxine dosage, 125 mcg/d. She had gained 27 kg and had developed significant edema. She had a grossly elevated thyroid-stimulating hormone level of 91 mIU/L. Her condition worsened, and a urinary protein measurement was 14.06 g/24 h-diagnostic of nephrotic syndrome. The levothyroxine dosage was increased to 225 mcg/d. Urinary total T4 concentration in a 24-hour sample was 59.0 microg/L (83.1 microg/24 h), indicating that a substantial fraction of her orally ingested T4 was lost in urine. Urinary total T4 excretion was significantly higher in patients with proteinuria (mean +/- standard deviation, 18.0 +/- 18.2 microg/L) vs control patients without proteinuria (mean, 3.8 +/- 1.8 microg/L) (P = .0014). CONCLUSION: In the patient described, urinary T4 loss due to proteinuria and nephrotic syndrome resulted in a severe exacerbation of underlying hypothyroidism.

Ocular Genetics Program: multidisciplinary care of patients with ocular genetic eye disease.

BACKGROUND: Patients who suffer from ocular genetic diseases have special needs in terms of diagnosis and management of rare entities, low-vision needs, genetic counselling, and psychosocial adjustments that are usually not addressed by an ophthalmologist alone. The Ocular Genetics Program (OGP) at the Hospital for Sick Children, Toronto, was established in 1994 to provide comprehensive, multidisciplinary care of patients with inherited eye disorders. We now assess the benefits of such a program and of integrating research into the care of patients. METHODS: We report our experience in developing a multidisciplinary ocular genetics program and the results of a pilot patient satisfaction survey that involved 61 patients. RESULTS: The OGP multidisciplinary aspects are described. Of the 61 patients surveyed, 98% stated that they were satisfied with the OGP; 93%-96% of patients were content with "one day of appointments", "understanding of eye problem", and "coordination of ancillary tests such as visual fields test, electrophysiology, and others"; and for 70%-86% of respondents "waiting time to get an appointment", "information received on current research", and "primary health care provider adequately informed" were satisfactory. INTERPRETATION: The OGP is a unique service in Canada, which strives to provide the comprehensive care needed by ocular genetic patients. High patient satisfaction is an indicator of the success of this approach. Long waiting times for appointments and application of laboratory research in clinical care remain challenging.

The clinical epidemiology of cardiovascular disease in chronic kidney disease.

PURPOSE OF REVIEW: To review recent publications concerning the epidemiology and management of cardiovascular disease in the stages of chronic kidney disease. RECENT FINDINGS: Chronic kidney disease is a state of increased risk for atherosclerotic and cardiomyopathic disease. The mechanisms of cardiovascular disease probably change with the different stages of chronic kidney disease. Both proteinuria and decreased glomerular filtration rate are probably independent cardiovascular disease risk factors, although the impact of the latter is modest. Traditional risk factors are important predictors of cardiovascular disease in chronic kidney disease. Recent randomized controlled trials and cohort studies have supported interventions for smoking cessation, blood pressure control, renin-angiotensin system blockade, the correction of lipid abnormalities, and utilizing antiplatelet agents. Some uraemia-related risk factors predict the development of cardiovascular disease, particularly hypoalbuminaemia, inflammation, anaemia, and homocysteinaemia. However, randomized controlled trials of anaemia correction and of an increased quantity of dialysis were negative. SUMMARY: The role of oxidant stress, divalent ion abnormalities, various lipid abnormalities and other potential factors require further investigation. To determine whether these uraemia-related factors are markers of cardiovascular disease risk or are actually cardiotoxic requires additional randomized controlled trials.
