摘要:

A tool was developed to assess attitudes of patients with cardiac disease toward performing prescribed behaviors of their medical regimen. Two groups of subjects with heart disease were used to examine validity and reliability of the Miller Attitude Scale. One group included 480 members of Mended Hearts, Inc., and the second group consisted of 35 patients diagnosed with a first myocardial infarction. The second group repeated the attitude scale six months post-hospitalization. Performance of the medical regimen by this group was verified at the six-month follow-up period. Using Spearman Rank Correlation, there was a significant relationship between attitudes and adherence behaviors for three of the five subscales. Alpha reliabilities revealed a high degree of internal consistency of scale items for all five subscales when testing both groups.A factor analysis resulted in eight factors accounting for the majority of the variance. Each of the five behaviors of the medical regimen clearly defined a factor supporting use of the Miller Attitude Scale for assessing attitudes of heart patients toward behaviors of their medical regimen.

摘要:

This descriptive-correlational study was undertaken in order to determine if there were differences in the health beliefs, health locus of control, and self concept of adult women who practice breast self-examination (BSE) as compared to those women who do not. A sample of 207 women, drawn from a variety of settings, completed the four questionnaires, which were the research instruments. Data were analyzed using means, standard deviations, point biserial correlations, multiple regression, and Pearson product moment correlations. Analysis of the data revealed there were differences between the practicer and non-practicer groups in terms of health beliefs, health locus of control, and self concept. Specifically, analysis revealed that being a practicer of BSE was correlated with higher levels of health beliefs and higher self-concept levels. Practicers tended to be less inclined to have a health locus of control that depended upon a powerful other.

摘要:

Recent studies by other investigators have shown that hypertensives are more hostile and anxious than normotensives. The first part of this study examined the relationship between blood pressure measured daily over a one-week period and responses to a series of questions specifically developed to distinguish hypertensives from normotensives. Responses from this sample of undergraduates did not distinguish those with high blood pressure from those with normal values. Mean resting blood pressure was related to hostility and anxiety factor scores among males but not among females. Our second study used a sample of municipal employees and examined blood pressure as a function of comparable anxiety and hostility scores as well as a trait measure of overall “engagement-involvement.” More highly engaged workers were no different in anxiety or hostility than less engaged workers. There was some evidence of more variable blood pressure for the former group. It is suggested that stable personality traits such as hostility and anxiety may both precede and follow the diagnosis of blood pressure. For nurses it is important to assess the patient's general psychological profile as well as his or her emotional state at the time of measurement. Repeated blood pressure readings are recommended especially for highly engaged individuals.

摘要:

A study was conducted to determine the effect of oxygen inhalation by nasal cannula on oral temperatures. One hundred healthy adult subjects were randomly assigned to a control and to three experimental groups that received 2, 4, and 6 liters per minute of oxygen for 30 minutes. Oral temperatures were measured before and 30 minutes after oxygen treatment. The data analysis did not show any significant effect of the treatment. This study encourages review of the common empirical practice of changing temperature sites from the preferred oral to the less acceptable rectal or axillary sites in patients receiving oxygen inhalation treatments.

摘要:

This study addressed the problem of monitoring serum glucose levels in persons suffering with diabetes mellitus.The purpose was to investigate the relationship between the renal threshold for glucose in diabetics and age, sex, type and duration of diabetes. The effects of insulin dose, race, and serum creatinine were investigated. Difference between double-void and triple-void urine glucose concentration was studied.The sample consisted of 40 adult diabetics who met selected criteria. The independent variables were determined from subjects' hospital records. The renal threshold for glucose was estimated by comparison of serum glucose concentrations and urine glucose grades. During a one-hour period blood was drawn and a double-void urine specimen and a triple-void urine specimen were collected. Blood and urine were analyzed for glucose with glucose oxidase as the reagent. Beginning with the morning after hospital admission, blood and urine were collected and analyzed three times each day for four days.During this study the term “estimated threshold interval” was used and defined. The terms “negative boundary point,” “positive boundary point,” and “inverted boundary points,” which are closely associated with the estimated threshold interval concept, were also used.Analysis of the data revealed that during 21 percent of the test periods the glucose concentration of double-void and triple-void urines differed. Decreases accounted for 73 percent and increases accounted for 27 percent of the changes. By employing the negative and positive boundaries of the estimated threshold interval associated with double-void and triple-void urine, four separate analyses of variance were made. The renal threshold for glucose had wide variability among individuals. The means of the negative boundary associated with double-void urine was 213; the positive boundary of double-void urine was 216; the negative boundary of triple-void urine was 215, and the mean of the positive boundary of triple-void urine was 243. The greatest probability found that any of the independent variables influenced the renal threshold for glucose was the effects of age (p = .08) and insulin dose (p = .07)on the negative boundary point associated with double-void urine. It was evident from theR2= 0.328 that the variability of the renal threshold for glucose is influenced by variables other than those studied.Concepts defined in this study may be useful to researchers who want to study the renal threshold for glucose of patients in the clinical area.

摘要:

A portable external pneumatic intermittent compression (EPIC) device has been successful in reducing peripheral edema. This study explored the effectiveness of EPIC for treating dependent pregnancy edema. In the study, 42 healthy pregnant women received EPIC for 30 minutes at 40 torr while in the left lateral recumbent position: Group One with mid-thigh boots, and Group Two with below-knee boots. Prior to compression, descriptive data were gathered, leg circumference measurements made, and surface skin temperatures recorded for three sites per leg. Vital signs were taken and pedal edema subjectively indexed. Following compression, circumferences, skin temperatures, vital signs, and edema indices were rerecorded. Three volumes were calculated for each leg using a mathematical model of leg segments as conical frustum units. Mean volume reductions for each leg were significant. The mid-thigh-length boots produced greater mean volume decreases. The volume decrease for calf, lower leg, and foot frustum units were significant. EPIC holds promise as a useful treatment for dependent pregnancy edema.

摘要:

The effects of specialty, setting, and provider group on the distributions of health problems managed by nurse practitioners and physicians in obstetric-gynecology, adult medicine, pediatrics, and family practice specialties are studied. Proportional samples by clinic were drawn from a total of 39,243 patient visits made to 16 ambulatory care clinics during an 18-week period. A Patient Encounter Form was used as the instrument and the ICD-9-CM was used as the coding system. Distributions of health problems differed between nurse practitioners and physicians in each clinic. Specialty affected the distributions of health problems managed by both provider groups. Setting affected the distributions of health problems for all specialties except the distributions of health problems not related to diseases or injuries (V codes) in family practice. Provider group effects were inconclusive. Community-based settings seem especially appropriate for nurse practitioner practice.

摘要:

The Patient Satisfaction Instrument (PSI) was developed over a series of five clinical and administrative studies during a period of eight years, with a total of 600 patients, primarily medical-surgical inpatients and outpatients. The process illustrates measurement precision by replication.The PSI is a Likert-type summated rating scale with three dimensions of patient satisfaction: technical-professional care, trust, patient education. It was adapted for use with inpatients from Risser's out-patient instrument. Internal consistency estimates appear satisfactory and stable across the various studies; for example, alpha coefficients for the Technical-Professional subscale average .79, Education coefficients average .78, and Trust coefficients average .88. Interitem, item-subscale, and inter-scale correlations corroborate the alphas. Construct validity estimates were made via convergent/discriminant technique, discriminance, and predictive modeling.Empirical correlations moderately substantiated the multiple, convergent/ discriminant predictions. Discriminance was strongly documented for all but the Education subscale, which had modest support. Predictive modeling produced moderate to strong validity estimates. Overall, the PSI has acceptable levels of validity and reliability with refinements indicated.
