Decision-making preference and opportunity in VA ambulatory care patients: association with patient satisfaction.

Using data from the Veterans Health Study, associations were examined for decision-making preference, decision-making opportunity, and satisfaction with medical care among a sample of 266 men who use Department of Veterans Affairs (VA) ambulatory health care services. Results indicated that veterans with a high preference for involvement in decision-making and low provider-offered decision-making opportunities had significantly lower satisfaction with medical care compared to veterans with either low preference for decision-making involvement with high or low opportunity, or those with a high decision-making preference and high decision-making opportunity. The findings suggest that health care providers may increase patient satisfaction with medical care by providing opportunities for decision-making to patients who prefer involvement in their health care decision-making. Provider strategies for increasing patient decision-making involvement are discussed.

The relationship of values to adjustment in illness: a model for nursing practice.

This paper proposes a model of the relationship between values, in particular health value, and adjustment to illness. The importance of values as well as the need for value change are described in the literature related to adjustment to physical disability and chronic illness. An empirical model, however, that explains the relationship of values to adjustment or adaptation has not been found by this researcher. Balance theory and its application to the abstract and perceived cognitions of health value and health perception are described here to explain the relationship of values like health value to outcomes associated with adjustment or adaptation to illness. The proposed model is based on the balance theories of Heider, Festinger and Feather. Hypotheses based on the model were tested and supported in a study of 100 adults with visible and invisible chronic illness. Nursing interventions based on the model are described and suggestions for further research discussed.

Pseudomonas maltophilia causing heroin-associated infective endocarditis.

The association of Pseudomonas maltophilia endocarditis in three patients with recent history of intravenous drug abuse is reported. All three patients had abnormal heart valves (two prosthetic and one rheumatic). A prominent characteristic of this uncommon pathogen is its in vitro resistance to the commonly used antimicrobials. Cure was achieved in all three cases. In two cases, synergistic antibiotic combinations were used. In one case, plasmid-mediated resistance to amikacin sulfate (Amikan, British; no comparable US product) emerged during therapy. The two patients with prosthetic valves received combined surgical and antibiotic therapy.

The influence of heart rate on pulmonary arterial-left ventricular pressure relationships at end-diastole.

Increased resistance to blood flow stemming from structural and functional abnormalities of the lungs may cause pressure in the pulmonary artery to exceed that in the left ventricle at the end of ventricular diastole. This study explores the possible contribution of heart rate to the diastolic pressure gradient observed in the presence of acutely induced hypoxia. Pulmonary hemodynamics were examined in mongrel dogs with chronic atrioventricular dissociation with and without hypoxia at two different heart rates and during sequential increments in heart rate while the animals breathed room air. Studies during sequential pacing indicate that heart rate was of greater importance than blood flow in determining the magnitude of the gradient. Heart rate has to be considered when the causes of pulmonary hypertension and the effects of drugs or other agents on the pulmonary circulation are being investigated.

Environmental factors in glue ear.

A survey of school children suffering from chronic secretory otitis media over an eight-year period compares the incidence in a city area and country area and various areas within the city. A factor in the causation of the condition appears to be poor living conditions and air pollution. An increase in the incidence occurred in both areas following a winter in which there was an exceptional incidence of influenza.
