Putting patients at the center of kidney care transitions: PREPARE NOW, a cluster randomized controlled trial

Care for patients transitioning from chronic kidney disease to kidney failure often falls short of meeting patients' needs. The PREPARE NOW study is a cluster randomized controlled trial studying the effectiveness of a pragmatic health system intervention, 'Patient Centered Kidney Transition Care,' a multi-component health system intervention designed to improve patients' preparation for kidney failure treatment. Patient-Centered Kidney Transition Care provides a suite of new electronic health information tools (including a disease registry and risk prediction tools) to help providers recognize patients in need of Kidney Transitions Care and focus their attention on patients' values and treatment preferences. Patient-Centered Kidney Transition Care also adds a 'Kidney Transitions Specialist' to the nephrology health care team to facilitate patients' self-management empowerment, shared-decision making, psychosocial support, care navigation, and health care team communication. The PREPARE NOW study is conducted among eight [8] outpatient nephrology clinics at Geisinger, a large integrated health system in rural Pennsylvania. Four randomly selected nephrology clinics employ the Patient Centered Kidney Transitions Care intervention while four clinics employ usual nephrology care. To assess intervention effectiveness, patient reported, biomedical, and health system outcomes are collected annually over a period of 36 months via telephone questionnaires and electronic health records. The PREPARE NOW Study may provide needed evidence on the effectiveness of patient-centered health system interventions to improve nephrology patients' experiences, capabilities, and clinical outcomes, and it will guide the implementation of similar interventions elsewhere.

The effects of selective response preparation on corticospinal excitability

OBJECTIVE

Both motor imagery and selective motor cues enhance performance. Motor cortex is activated during motor imagery. We wanted to learn if selective motor cueing also activates motor cortex.

METHODS

We gave normal right-handed subjects information about which hand to use to respond to an imperative stimulus (selective intention) or where in space an imperative stimulus would occur (selective attention). To minimize anticipatory responses, warning stimulus validity was 80%. During this choice reaction time task, we recorded magnetic motor evoked potentials. Imperative stimuli and transcranial magnetic stimulation were presented randomly to assess the effect of warning cues on reaction times and corticospinal excitability.

RESULTS

Selective intentional and attentional warning cues reduced reaction times, but neither stimulus altered motor evoked potentials.

CONCLUSIONS

These results suggest that unlike motor imagery, selective intention to respond to an imperative stimulus and shifting spatial attention to an imperative stimulus do not alter corticospinal excitability.

Dietary caffeine, fluid intake and urinary incontinence in older rural women

Forty-one women completed the first phase (self-monitoring) of the Behavioral Management for Continence (BMC) intervention, while working with a nurse during home visits to reduce involuntary urine loss as part of the parent study involving older, rural women living at home. A decrease in dietary caffeine intake and an increase in fluid intake were most frequently recommended. The relationship between a decrease in the amount of dietary caffeine consumed and fewer daytime episodes of involuntary urine loss approached significance -P = 0.0744- whereas an increase in the average amount of fluid intake was significantly related to an increase in the average volume of urine voided -P = 0.0479- and not to involuntary urine loss.

A rodent model of spontaneous stereotypy: initial characterization of developmental, environmental, and neurobiological factors

Stereotypies are patterns of motor behavior that are repetitive, excessive, topographically invariant, and that lack any obvious function or purpose. In humans, stereotyped behaviors are associated with psychiatric, neurological, and developmental disorders. In animals, stereotypy has been frequently associated with adverse environmental circumstances and often related to alterations in striatal dopamine. To assess the development of stereotyped behaviors and to test the hypothesis that these behaviors are associated with environmental restriction, deer mice were housed in either standard laboratory cages or larger, enriched cages, and the development of stereotypy was followed from weaning over a 17-week period. Standard-caged deer mice engaged in stereotyped behaviors at a higher rate and developed these behaviors more quickly when compared to animals in enriched caging. Additionally, enriched caging was associated with higher rates of patterned running, whereas jumping and backward somersaulting were typically observed in standard cages. In addition, there was a significant effect of litter, but no effect of sex or cage, on the time to develop stereotypy. No differences were found in the density of either striatal D1 or D2 dopamine receptors or the concentration of striatal dopamine or its metabolites as a function of rearing condition or as a function of whether the animals developed stereotypy. These results characterize the development of stereotypies in this species, demonstrate the importance of environmental conditions in the genesis of stereotypy, and suggest that alterations in striatal dopamine content or dopamine receptor density do not account for the expression of stereotyped behaviors in this model.

Issues related to using a short-form of the Center for Epidemiological Studies-Depression Scale

The study examined the reliability and validity, including the factor structure, of a 10-item abbreviated version of the Center for Epidemiological Studies-Depression (CES-Depression) scale when administered as part of a mail questionnaire. It also examined patterns of nonresponse to items and the effects of imputation of data for missing items on the factor structure of the inventory. A problem of missing data has been reported even with interview administration of the CES-Depression. Researchers have varied considerably in the amount of imputation used to replace missing datapoints. In this study, factor structures varied when items were imputed. In addition, those subjects with complete data were compared with those with up to two imputed datapoints. Those subjects with imputed data were more likely to be female, have lower functional status scores, lower self-reported health status, more advanced age, and a greater number of depressive symptoms than those with no missing data. While the estimate of coefficient alpha of .78 indicated the inventory was reliable, the effects of missing data on construct validity were problematic.

Role orientation and community pharmacists' participation in a project to improve patient care

Community pharmacists are being assigned increased responsibility in assuring the appropriateness and effectiveness of drug therapy. This increased responsibility is reflected in recently passed legislation (OBRA '90) in the United States that requires pharmacists to counsel patients about prescriptions received and to engage in prospective drug use review for Medicaid recipients. The potential impact of this legislation is unclear due to a dearth of research evaluating the effects of community pharmacists' activities on medication use. In addition, there is little research on pharmacists' willingness to assume increased responsibility. Research that would demonstrate the effectiveness of community pharmacists in improving therapeutic outcomes is hampered by problems inherent in conducting experimentally designed research in field settings. This paper examines two issues of concern in such studies--namely, the extent to which those who agree to participate in a demonstration project differ from those who decline to participate and the extent to which differential dropout from treatment and control conditions compromise the comparability of the two groups. Specifically, this report examines pharmacist characteristics related to participation in a demonstration project to improve the care of elderly patients. Community pharmacists in Florida who had earlier been asked to participate in a demonstration project (N = 418) were sent mail questionnaires to assess their attitudinal, demographic and employment characteristics. In particular, researchers were interested in the role orientation of pharmacists in regard to patient counseling and physician consultation, satisfaction with current jobs and career choices, employment settings and treatment vs control group assignment as predictors of participation in the research project. Demographic characteristics were also examined as possible predictors of participation.(ABSTRACT TRUNCATED AT 250 WORDS)

Effects of an education program for community pharmacists on detecting drug-related problems in elderly patients

Community pharmacists are in a position to assume increased responsibility for preventing and resolving drug-related problems in ambulatory patients. Such an expanded role is mandated under provisions of the Omnibus Budget Reconciliation Act of 1990. The need for pharmacist oversight of drug therapy may be most acute in elderly patients. This study reports on a program to teach community pharmacists a process of assessing drug therapy of elderly patients and intervening to correct problems. Community pharmacists (N = 102) were assigned to treatment and control conditions. Both groups targeted patients meeting criteria and enrolled them into the study. Treatment group pharmacists, who participated in a training program, also assessed the medication use of enrolled patients to identify and resolve medication-related problems. Patients (N = 762) were telephoned by researchers 1 month after enrollment for an interview. Comparisons between treatment and control group patients were made on reports of pharmacist activities, knowledge of regimens, compliance, and potential drug therapy problems, such as interactions and side effects. Treatment patients were more likely to report that pharmacists provided information and assessed for problems than were control patients. These differences were maintained on 3-month follow-up questionnaires. No differences were found on the odds that patients indicated misunderstanding of regimens, non-compliance, or potential therapeutic problems.

Comparison of staple and suture techniques for end-to-end anastomosis of the small colon in horses

Two techniques for end-to-end anastomosis of the small colon were evaluated in each of 6 horses. A simple interrupted suture pattern that excluded the mucosa and was oversewn with an inverting suture was compared with a triangulated double-row pattern of stainless steel staples. Anastomotic sites were evaluated at 2 weeks, 2 months, and 6 months for extent of abdominal adhesions, lumen diameter at anastomotic sites, bursting pressures, and healing response. Clinical postoperative complications were not associated with either technique. At postmortem examination, there was extensive adhesion formation from the mesocolon to the stapled anastomotic site. The suture technique resulted in greater luminal diameters (P less than or equal to 0.05), with good apposition of the tissue layers. Staples were missing as early as 2 weeks after surgery, and their loss was associated with separation of the muscularis at later evaluation periods. Regardless of technique, all but one anastomotic segment burst away from the anastomotic site along the mesenteric taenial band. For the 12 anastomoses performed in normal horses, the suturing technique was better than the stapling technique because of significantly larger lumen diameters, better anastomotic healing, and minimal intra-abdominal adhesion formation.

A multistage model of hospital bed requirements

This article presents a model for projecting future hospital bed requirements, based on clinical judgment and basic probability theory. Clinical judgment is used to define various categories of care, including a category for patients who are inappropriately hospitalized, for a large teaching hospital with a heavy indigent and psychiatric workload. Survey results and discharge abstract data are then used to calculate expected discharges and patient days for each clinical category. These expected discharges and patient days are converted into estimated bed requirements using a simple deterministic equation. Results of this multistage model are compared with the results obtained from exercising the simple deterministic equation alone. Because the multistage model removes patients from the hospital if they are deemed inappropriately placed, this model results in the projection of 5.1 percent fewer hospital beds than the simple deterministic equation alone.

Nursing administration research in hospitals and schools of nursing

"Nursing service administration is in the most desperate need of research..." So said Herman Finer, well-known professor at the University of Chicago and in 1952, director of the Kellogg Nursing Service Administration Research Project. Today, 35 years later, the same need holds true. Administrators in hospitals and schools of nursing were canvassed to discover the nature of nursing administration research already in progress. Information about what is being studied, and amounts and sources of funding can be useful to nurse executives who are planning to implement research projects that build on existing knowledge. Findings from the study can also contribute to development of an overdue national research agenda for nursing administration.

Delineation of nursing administration research priorities

The purposes of this national study were to determine: (a) a definition of nursing administration research and (b) priority nursing administration research questions. Brainstorming was used initially with Council on Graduate Education for Administration in Nursing (CGEAN) members in 1984, to delineate concepts for definitions. Definitions and research questions were generated and rated in a three-round Delphi survey by 129 experts from nursing and health administration. According to the most widely supported definition, nursing administration research is concerned with establishing costs of nursing care, examining the relationships between nursing services and quality patient care, and viewing problems of nursing service delivery within the broader context of policy analysis and delivery of health services. The research question of most importance was: What are the cost-effective components of clinical nursing care that yield high patient satisfaction, decrease the number of complications, and shorten hospital stay for identified groups of patients? In a scenario exercise at the 1985 CGEAN meeting, additional priorities identified were vulnerable populations and equity.

Human thrombocytopenia is associated with structural abnormalities of the endothelium that are ameliorated by glucocorticosteroid administration

Capillary fragility is characteristic of severe thrombocytopenia. This mechanical weakness may not be solely accounted for by decreased ability of platelets to repair endothelial breaks. Platelets may have a role in maintaining endothelial hemostasis. This laboratory has demonstrated thinning of capillary endothelium in experimental thrombocytopenia. We now report similar findings in human thrombocytopenia. Capillary endothelium supplying either skin or skeletal muscle was found to have a mean thickness only half that of normal as well as frequent very thinned areas, including some fenestrations. All findings reverted toward normal after four days of prednisone administration at a time the degree of thrombocytopenia was equally severe. These findings are consistent with the hypothesis that platelets are necessary for normal structure and function of endothelial cells and that glucocorticosteroid administration may ameliorate the pathophysiology of thrombocytopenia.

Thiazide diuretics and bone mineral content in postmenopausal women

This retrospective study of 54 postmenopausal women taking thiazide diuretics found that bone mineral measurements and bone fracture prevalence did not differ significantly from those of matched control subjects. Matching on the variables of type of menopause (surgical/nonsurgical), years postmenopausal, duration of estrogen therapy (if any), daily intake of dietary and supplemental calcium and vitamin D, and Quetelet index was done without knowledge of the bone mineral measurements. Bone mass was recorded as the bone mineral content and bone density of the distal and midshaft radius. Only fractures associated with osteoporosis (hip, rib, vertebrae, and wrist) were recorded. This study suggests that thiazide diuretics do not provide protection against osteoporosis.

Uterine blood flow: periodic fluctuations of its rate during pregnancy

Daily measurements of the rate of uterine blood flow (ml/min) during the last half of pregnancy of four normal sheep reflected a 17-day cyclic fluctuation (range, 9.5-42 days) superimposed on a linear increase over time. The cyclic increase was not detected in two (of 7) intact ewes or in four pregnant ewes that had been ovariectomized. The cyclic pattern of increase may be related to ovarian activity.

Accuracy of two systems for blood glucose monitoring without a meter (Chemstrip/Visidex)

Blood specimens collected from 159 campers were tested using Visidex (VD) (Ames Company, Elkhart, Indiana) and Chemstrip (CS) (Bio-Dynamics, Boehringer Mannheim, Indianapolis, Indiana) compared with glucose analyzer (GA) results. Readers were physicians, two with no prior experience using either strip and two with some experience using CS. Subsequently, 30 clinic patients and 4 staff contributed random specimens that were read by a trained novice as 68 discrete samples and compared with GA results. In both studies readers did not place blood on the strips and were thus blinded as to source and the possible previous reading with the other strip. Correlations of VD and CS with GA for camp and clinic data were calculated. Data were compared for reliability and errors greater than 20% of reference values (GA) were compared for VD and CS. CS correlated better with GA than did VD estimates. Reliability was also significantly greater for CS than for VD readings. Both of these visually read methods provided clinically useful estimates of glycemia.
