Nursing care quality: process and outcome relationships.

The relationships between variables in a proposed model for the quality of nursing care provided in the home were examined using a cross-sectional correlational design. Sixty patients discharged from a home-care agency were interviewed in their homes using instruments to measure the model's 7 variables. It was proposed that nursing care provided is related to 3 aspects of the interpersonal process--affective support, health information adequacy, and decisional control--and that these 3 variables are related to 3 outcomes--adherence, symptoms, and well-being.The findings support relationships between technical and interpersonal process components. Significant relationships were found between health information adequacy and adherence and between decisional control and well-being.The authors conclude that further refinement of the model will help to build a stronger foundation for the study and provision of quality nursing care.     

Physician documentation of diabetes care: use of a diabetes flow sheet and patient education clinic

We assessed two interventions designed to improve the care of patients with diabetes mellitus by documenting the complications of their disease. These were a flow sheet, included with outpatient medical records, and a weekly patient education clinic, in which a nurse educator provided individualized instruction to patients with diabetes. Physician compliance with recommendations of the National Diabetes Advisory Board for diabetes care was measured before (n = 45) and after (n = 158) these interventions. The numbers of referrals to ophthalmologists increased from 22% to 46%, urinalyses increased from 58% to 77%, and lower extremity examinations increased from 36% to 61%. Nutrition education documentation increased from 51% to 69%, and diabetes education documentation increased from 31% to 61%. These results suggest that a significant improvement in physicians' documentation of care of patients with diabetes can be achieved by using a flow sheet and a diabetes patient education clinic.     

Care process and patient outcome in diabetes mellitus.

The relationship between the process of medical care and patient outcome is a central issue in health services research. We examined this relationship in 244 patients with adult-onset diabetes mellitus, who were under the care of private internists and family physicians. Process measures included physician awareness of patients' concerns, communication of information from physician to patient, medication-taking behavior, physician adherence to minimum care criteria, and extent of patient utilization of services. Outcomes measured during and after a 6-month follow-up period, included diabetic control status and patient satisfaction with medical care. Potentially confounding variables included practice and physician characteristics, patient demographic characteristics, and measures of disease severity. There was a small statistically significant correlation between physician awareness and control status, but the association was not maintained when controlling for other variables. Communication of information from physician to patient was significantly (p less than .005) associated with satisfaction in the multiple regression analysis but explained only 4 per cent of the variance in patient satisfaction. Thus, in patients under treatment for diabetes, there was little association between certain measures of care process and patient outcome. We suggest that process and outcome assessments are distinct but complementary aspects of quality of care.     

Physician performance assessment: nonequivalence of primary care measures

BACKGROUND: Assessment of the performance of primary care physicians requires multiple, reliable measures. This article explores the appropriateness of selected Health Plan Employer Data and Information Set (HEDIS) measures, developed to assess health plans, to assess individual physician performance. OBJECTIVES: To determine the consistency and reliability of 4 measures of primary care physician performance measures: cancer screening, diabetic management, patient satisfaction, and ambulatory costs. METHODS: The study population consisted of all 194 family practitioners and general internists providing ambulatory services in 1998 to a defined patient panel of 320,000 adult health maintenance organization members. Administrative data on physician practice and performance were assessed with multiple regression and analysis of variance. RESULTS: Each performance measure was significantly related to 1 or 2 of the other measures: high cancer screening rates with good diabetic management and high patient satisfaction, good diabetic management with high cancer screening rates, high patient satisfaction with high cancer screening rates and high ambulatory costs, or high ambulatory costs with higher patient satisfaction. Although 76% of the physicians ranked in the highest third for at least 1 measure, 81% of these high performers ranked in the lower third for at least 1 other measure. Three percent of physicians ranked exclusively in the top or bottom third on all measures. CONCLUSIONS: Care should be taken in assessing physicians based on narrow performance measures. Assessments of individual physicians with current performance measures might identify areas in which improvement is needed and to provide feedback to improve performance quality and efficiency. However, assumptions should not be made from one measure of performance to another.     

Patient-reported access to primary care in Ontario: Effect of organizational characteristics

Objective

To describe patient-reported access to primary health care across 4 organizational models of primary care in Ontario, and to explore how access is associated with patient, provider, and practice characteristics.

Design

Cross-sectional survey.

Setting

One hundred thirty-seven randomly selected primary care practices in Ontario using 1 of 4 delivery models (fee for service, established capitation, reformed capitation, and community health centres).

Participants

Patients included were at least 18 years of age, were not severely ill or cognitively impaired, were not known to the survey administrator, had consenting providers at 1 of the participating primary care practices, and were able to communicate in English or French either directly or through a translator.

Main outcome measures

Patient-reported access was measured by a 4-item scale derived from the previously validated adult version of the Primary Care Assessment Tool. Questions were asked about physician availability during and outside of regular office hours and access to health information via telephone. Responses to the scale were normalized, with higher scores reflecting greater patient-reported access. Linear regressions were used to identify characteristics independently associated with access to care.

Results

Established capitation model practices had the highest patient-reported access, although the difference in scores between models was small. Our multilevel regression model identified several patient factors that were significantly (P = .05) associated with higher patient-reported access, including older age, female sex, good-to-excellent self-reported health, less mental health disability, and not working. Provider experience (measured as years since graduation) was the only provider or practice characteristic independently associated with improved patient-reported access.

Conclusion

This study adds to what is known about access to primary care. The study found that established capitation models outperformed all the other organizational models, including reformed capitation models, independent of provider and practice variables save provider experience. This suggests that the capitation models might provide better access to care and that it might take time to realize the benefits of organizational reforms.     

Intensive care 1980–1995: change in patient characteristics, nursing workload and outcome

Objective: To assess temporal changes in patient characteristics, nursing workload and outcome of the patients and to compare the actual amount of available nursing staff with the estimated needs in a medical-surgical ICU. Design: Retrospective analysis of prospectively collected data. Setting: A medical-surgical adult intensive care unit (ICU) in a Swiss university hospital. Patients: Data of all patients staying in the ICU between January 1980 and December 1995 were included. Interventions: None. Measurements and results: The estimated number of nurses needed was defined according to the Swiss Society of Intensive Care Medicine (SGI) grading system: category I = one nurse/patient/shift ( = 8 h), category II = one nurse/two patients/shift, category III = one nurse/three patients/shift. An intervention score (IS) was obtained, based on a number of specific activities in the ICU. There was a total of 35,327 patients (32 % medical and 68 % postoperative/trauma patients). Over time, the number of patients per year increased (1980/1995: 1,825/2,305, p < 0.001) and the length of ICU stay (LOS) decreased (4.1/3.8 days, p < 0.013). There was an increase in the number of patients aged > 70 years (19 %/28 %, p < 0.001), and a decrease in the number of patients < 60 years (58 % /41 %, p < 0.001). During the same time period, the IS increased two-fold. Measurement of nursing workload showed an increase over time. The number of nursing days per year increased (1980/1995: 7454/8681, p < 0.019), as did the relative amount of patients in category I (49 %/71 %, p < 0.001), whereas the portion of patients in category II (41 %/28 %, p < 0.019) and category III (10 %/0 %) decreased. During the same time period, mortality at ICU discharge decreased (9.0 %/7.0 %, p < 0.002). Conclusions: During the last 16 years, there has been a marked increase in workload at this medical-surgical ICU. Despite an increase in the number of severely sick patients (as defined by the nursing grading system) and patient age, ICU mortality and LOS declined from 1980 to 1995. This may be ascribed to improved patient treatment or care. Whether an increasingly liberal discharge policy (transfer to newly opened intermediate care units, transfer of patients expected to die to the ward) or a more rigorous triage (denying admission to patients with a very poor prognosis) are confounding factors cannot be answered by this investigation. The present data provide support for the tenet that there is a trend toward more complex therapies in increasingly older patients in tertiary care ICUs. Calculations for the number or nurses needed in an ICU should take into account the increased turnover of patients and the changing patient characteristics. Received: 30.

The nursing process: a problem-solving approach to patient care

The forces that motivate and sustain exchanges within systems are recognized discrepancies between system goals and situations in which these are unfulfilled (Parsons, 1951).Nursing behaviour is in this sense caused by expectations of the future; discrete acts are linked in goal-directed processes characterized by a self-regulating and continuous evaluation of actual in relation to intended states. Discrepancies between what is thought to be both desirable and realistically possible on the one hand, and present levels of performance on the other, provide motivation for the formulation and implementation of policy and initiate remedial action.     

Physician, organizational, and patient factors associated with suboptimal blood pressure management in type 2 diabetic patients in primary care

OBJECTIVE: To assess the quality of hypertension care in patients with type 2 diabetes in general practice and identify physician, organizational, and patient factors associated with suboptimal care. RESEARCH DESIGN AND METHODS: Data from 895 randomly selected diabetic patients were extracted from the electronic medical records of 95 general practitioners. Physician and organizational characteristics were collected with a questionnaire. We conducted a multilevel analysis to identify associations with blood pressure registration, hypertension treatment, and achievement of target blood pressure levels. RESULTS: For 652 patients (73%), a blood pressure measurement was recorded in the last year. Of these patients, 132 (20%) reached a target level of 135/85 mmHg. In total, 595 patients were classified as having hypertension, of whom 192 received no treatment (32%), 193 received an ACE inhibitor (32%), and 210 received other antihypertensives. Patients visiting a diabetes facility, referred to a specialist, with a female general practitioner, or with a general practitioner with 相似文献   

Application of physiotherapy outcome measures to the managed care model

Managed Care (MC) is a multidisciplinary model for health care delivery that organizes and sequences the caregiving process. Its objectives include: 1) to reduce length of stay and resource consumption, and 2) to measure, maintain or improve patient outcomes related to care received. Our tertiary care facility is the first Canadian hospital to implement MC. Patient care is directed through the use of a Care Map. Each map is specific to a pathological state and its treatment, i.e. Total Knee Replacement (TKR), and consists of a Patient Problem List, with related patient-centred outcomes, and a Critical Path. The Critical Path outlines the temporal sequence of the provision of care. Most key events on a Care Map are determined anecdotally. The purpose of this project was to collect outcome information in patients assigned to the Total Knee Replacement Care Map in an attempt to validate the existing Care Map or make recommendations for revisions. Inter-rater and intra-rater reliability of knee range of motion-was calculated using the Intra Class Correlation Coefficient (ICC). ICC values ranged from .64-.97. Seventeen patients were assessed. All patients were measured on Day 6 and 8 of the Care Map. This process has resulted in validation of certain range estimates and recommendations for revision of others.     

Using process mapping to improve nursing practice and patient care

Process mapping is a technique that models the relationship between activities, people and resources. It is used to develop a better understanding of the patient's experience and to drive forward service modernization. This paper offers a brief guide to process mapping and examines the potential impact it may have on nursing services and patient care.     

Correlation of patient-reported outcome measures to performance-based function in critical care survivors: PREDICTABLE

BackgroundEstablishing sequela following critical illness is a public health priority; however, recruitment and retention of this cohort make assessing functional outcomes difficult. Completing patient-reported outcome measures (PROMs) via telephone may improve participant and researcher involvement; however, there is little evidence regarding the correlation of PROMs to performance-based outcome measures in critical care survivors.ObjectivesThe objective of this study was to assess the relationship between self-reported and performance-based measures of function in survivors of critical illness.MethodsThis was a nested cohort study of patients enrolled within a previously published study determining predictors of disability-free survival. Spearman's correlation (r_s) was calculated between four performance-based outcomes (the Functional Independence Measure [FIM], 6-min walk distance [6MWD], Functional Reach Test [FRT], and grip strength) that were collected during a home visit 6 months following their intensive care unit admission, with two commonly used PROMs (World Health Organization Disability Assessment Scale 2.0 12 Level [WHODAS 2.0] and EuroQol-5 Dimension-5 Level [EQ-5D-5L]) obtained via phone interview (via the PREDICT study) at the same time point.ResultsThere were 38 PROMs obtained from 40 recruited patients (mean age = 59.8 ± 16 yrs, M:F = 24:16). All 40 completed the FIM and grip strength, 37 the 6MWD, and 39 the FRT. A strong correlation was found between the primary outcome of the WHODAS 2.0 with all performance-based outcomes apart from grip strength where a moderate correlation was identified. Although strong correlations were also established between the EQ-5D-5L utility score and the FIM, 6MWD, and FRT, it only correlated weakly with grip strength. The EQ-5D overall global health rating only had very weak to moderate correlations with the performance-based outcomes.ConclusionThe WHODAS 2.0 correlated stronger across multiple performance-based outcome measures of functional recovery and is recommended for use in survivors of critical illness.
