Longitudinal Changes in the Use of PD Assistance for Patients Maintained on Peritoneal Dialysis.

Background: Home dialysis therapies, such as peritoneal dialysis (PD), offer flexibility and improved well-being, particularly for older individuals. However, a substantial proportion require assistance with personal care and health care-related tasks. We hypothesized that patients and families would require less PD assistance as they became more familiar with PD-related tasks. The study objective was to assess whether the nature of, and need for, PD assistance decreased over time. Methods: Using a multicentered, prospective, observational study design, patients aged ≥50 years were recruited from those starting PD. Patients underwent formal evaluation using validated components of a Comprehensive Geriatric Assessment at baseline, and they were followed monthly and administered a questionnaire about the need for assistance with PD-related tasks. Results: A total of 111 patients (age 69±10 years, 68% men, and 56% diabetic) were followed for a total of 609 patient-months. Of those who needed help, 40% had help from a family member, and 33% were helped by nurses. Both the quantity and nature of help received by patients remained generally stable throughout follow-up and did not vary according to age, frailty, functional dependence, or cognitive impairment (P=0.93). The proportion of patients needing help varied widely across the 13 different tasks but appeared relatively stable across time. The paid-unpaid caregiver ratio for the different tasks did not change over time. Conclusions: Older patients initiating PD in the outpatient setting have a high need for assistance with PD-related tasks, which seems to persist over the initial 6-month period.

PD Assistance and Relationship to Co-Existing Geriatric Syndromes in Incident Peritoneal Dialysis Therapy Patients.

Background:Home dialysis therapies, including peritoneal dialysis (PD), are preferred treatment strategies, offering flexibility and improved wellbeing. However, patients with complex disease and comorbidity may require assistance with personal care and healthcare-related tasks. The study objective was to formally assess the type and frequency of PD assistance received by patients over 50, and the relationship to observed frailty, functional status, and cognitive ability at the time of PD therapy initiation.Methods:Using a multicentered, prospective observational study design, patients aged ≥ 50 years were recruited from those starting PD. Patients underwent formal evaluation using validated components of a Comprehensive Geriatric Assessment. The receipt and nature of assistance with PD tasks were assessed 1 month after dialysis start by questionnaire.Results:A total of 121 patients (age 69 ± 10 years, 67% male, 54% diabetic) were recruited. A total of 75 (62%) patients received assistance for a variety of tasks from friends or family (n = 41, 34%) or a paid caregiver (n = 34, 28%) 1 month after starting dialysis. At baseline, there was a high prevalence of functional dependency (79/120, 66%), frailty (71/110, 65%), and impaired cognition (68/115, 59%). Only 5% were fully independent, clinically robust, and scored within the normal range on cognitive testing. Factors associated with PD assistance included comorbidity (p < 0.03), cognitive impairment (p < 0.0001), and functional dependence (p < 0.02).Conclusion:Older patients initiating PD in the outpatient setting have high rates of frailty, functional dependence, and cognitive changes at the time they initiate dialysis. More research is required to better understand how those factors contribute to the use of PD assistance.

Conquering capacity.

Recognizing existing capacity constraints and the accompanying lost revenue and market share, Lucile Packard Children's Hospital at Stanford implemented an improvement initiative, beginning with an assessment of its patient flow processes. Key success factors included: Measuring to improve patient flow, increasing care and service coordination, redefining staffing and job functions, creating and sustaining culture change.

The effects of atypical antipsychotics on visceral fat distribution in first episode, drug-naive patients with schizophrenia.

The aim of this study was to determine the location of antipsychotic-induced weight gain in drug naïve, first episode patients with schizophrenia. Various fatness and fat distribution parameters (by Computerized Tomography scanning and anthropometry) and 1600 hr plasma cortisol were measured in 19 (15 men and 4 women) subjects with schizophrenia (mean age = 31.0 years; mean body mass index [BMI] = 24.6 kg/m2) and an equal number of age- and sex- matched controls (mean age = 32.6 yr; mean BMI = 23.0 kg/m2). Patients were then given either olanzapine or risperidone. Sixteen patients were re-tested following a treatment period lasting approximately 6 months. Patients with schizophrenia, had significantly more intra-abdominal fat [IAF] (116.8 +/- 20.2 cm2 vs. 38.0 +/- 4.8 cm2, respectively; t = 3.80, df = 18, p < 0.0001) and had higher levels of plasma cortisol (360.2 +/- 49.6 nmol/L vs. 192.7 +/- 19.7 nmol/L, respectively; t = 3.13, df = 18, p < 0.003) than appropriately matched control subjects. Treatment with atypical antipsychotics did not result in a significant increase in IAF (116.8 +/- 20.2 cm2 vs. 131.7 +/- 20.9 cm2; p = NS) though visceral fat stores still remained significantly higher than those seen in controls (38.0 +/- 4.8 cm2) (F = 9.34; df = 2, 51; p < 0.0003). However, plasma levels of cortisol did significantly decrease (360.2 +/- 49.6 nmol/L +/- vs. 316.2 +/- 48.4 nmol/L; p < 0.05). Pre-treatment levels of IAF did not differ between those who received risperidone and those who were given olanzapine (123.0 +/- 35.9 cm2 vs. 113.1 +/- 15.7 cm2, respectively; t = 0.20, df = 16, p < 0.84). The increase in IAF did not differ between those given risperidone and those who received olanzapine (26.9 +/- 12.1 cm2 vs. 18.24 +/- 11.44 cm2, respectively; t = 0.50, df = 16, p < 0.63). Patients with drug naïve, first episode, schizophrenia have higher levels of visceral fats stores as compared to matched control subjects. Treatment with atypical antipsychotics does not result in a significant increase in IAF distribution.
