RESUMEN
BACKGROUND: Knowledge of ambulatory patients' satisfaction with clinic visits help improve communication and delivery of healthcare. The goal was to examine patient satisfaction in a primary care setting, identify how selected patient and physician setting and characteristics affected satisfaction, and determine if feedback provided to medical directors over time impacted patient satisfaction. METHODS: A three-phase, semi-quantitative analysis was performed using anonymous, validated patient satisfaction surveys collected from 889 ambulatory outpatients in 6 healthcare centers over 5-years. Patients' responses to 21 questions were analyzed by principal components varimax rotated factor analysis. Three classifiable components emerged: Satisfaction with Physician, Availability/Convenience, and Orderly/Time. To study the effects of several independent variables (location of clinics, patients' and physicians' age, education level and duration at the clinic), data were subjected to multivariate analysis of variance (MANOVA).. RESULTS: Changes in the healthcare centers over time were not significantly related to patient satisfaction. However, location of the center did affect satisfaction. Urban patients were more satisfied with their physicians than rural, and inner city patients were less satisfied than urban or rural on Availability/Convenience and less satisfied than urban patients on Orderly/Time. How long a patient attended a center most affected satisfaction, with patients attending >10 years more satisfied in all three components than those attending <1-5 years. Level of education affected patients' satisfaction only in the component Orderly/Time; patients without a high school education were significantly less satisfied than those with more. Patients in their 40's were significantly less satisfied in Availability/Convenience than those >60 years old. Patients were significantly more satisfied with their 30-40 year-old physicians compared with those over 60. On Orderly/Time, patients were more satisfied with physicians who were in their 50's than physicians >60. CONCLUSIONS: Improvement in patient satisfaction includes a need for immediate, specific feedback. Although Medical Directors received feedback yearly, we found no significant changes in patient satisfaction over time. Our results suggest that, to increase satisfaction, patients with lower education, those who are sicker, and those who are new to the center likely would benefit from additional high quality interactions with their physicians.

BACKGROUND: Although nitric oxide (NO) synthesis is increased in periodontal disease (PD), little is known about the possible sources of production by gingival tissues. In fact, gingival tissues from patients with periodontitis demonstrate greater levels of inducible nitric oxide (iNOS) expression than healthy tissue. Macrophages are the source of the iNOS expression, with endothelial cells also contributing. In the present study, our hypothesis has been that human gingival fibroblasts (HGF) also have the ability to produce NO. We have established for the first time that HGF express increased levels of iNOS and modulate NO synthesis in response to proinflammatory cytokines that act synergistically. METHODS: NO production under basal conditions or following incubation with tumor necrosis factor (TNF-alpha), interleukin (IL)-1beta, and interferon (IFN)-gamma was assessed by measurement of stable NO metabolites, nitrite, and nitrate, in a microplate adaptation of the Griess assay. Total RNA was isolated from HGF for determination of iNOS mRNA levels. RESULTS: We have shown that NO production is elevated in HGF that are stimulated simultaneously by TNF-alpha, IL-1beta, and IFN-gamma. Northern blot analysis confirmed that the production of iNOS mRNA by HGF is upregulated in the presence of these cytokines. Addition of mercaptoethyl guanidine (MEG), a specific inhibitor of iNOS, profoundly reduced the production of NO in HGF. Non specific inhibitors of iNOS, L-NG-monomethyl arginine (L-NMMA), and L-arginine-methyl ester (L-NAME) had little or no effect on NO produced in HGF. CONCLUSIONS: These results suggest that elevated NO production could be important in the pathogenesis of PD, and also suggest the ability of an iNOS inhibitor to modulate the disease. Treatments with drugs to block the production of nitric oxide or block its effects might be therapeutically valuable.
