Unexplained symptoms in primary care: perspectives of doctors and patients.

This study evaluated unexplained symptoms in primary care from the perspective of both patients and physicians. The data were obtained from two 1998 statewide surveys, one targeting Medicaid patients and the other all primary care physicians in the state. There were 439 patients who responded (45% response rate) and 280 primary care physicians who responded (33% response rate). Half of the patients and half of the physicians were in non-metropolitan counties. Half of the patients reported unexplained symptom usually or always, and 75% of whom sought help for these symptoms. Fifty-two percent of these patients believed their physician was very concerned about their unexplained symptoms. Eighty percent of them rated their physician as providing the best possible care compared to only 49% of patients whose physician did not care about their unexplained symptoms (P=.001). Among the physicians, only 14% reported very good or excellent satisfaction with managing unexplained symptoms as compared to 44% who claimed similar satisfaction in managing psychological problems. Physicians who saw themselves as more effective in dealing with somatoform symptoms were more likely to be in solo practice (P<.005), or in the same location for at least five years (P=.04). Residence in a nonmetropolitan county did not affect patient reporting of symptoms, patient perception of physician concern about symptoms, or physician satisfaction in managing these symptoms. These results indicate the prevalence and importance of unexplained symptoms in the Medicaid population and the comfort of physicians in managing these symptoms. There is an unmet need among primary care physicians to learn how to manage patients with unexplained symptoms.

Prognostic factors for persons with idiopathic chronic fatigue.

BACKGROUND: The simultaneous examination of a large number of patient characteristics in a prospective study of patients with chronic fatigue. OBJECTIVE: To compare the relative importance of these characteristics as prognostic factors. METHODS: The data analyzed were from 199 subjects in a registry of persons who were aged 18 years or older and had idiopathic fatigue for at least 6 months. All subjects completed an extensive baseline questionnaire that provided information about fatigue, demographic characteristics, medical conditions, lifestyle, sleeping habits, psychological characteristics, and the presence of criteria for chronic fatigue syndrome. Changes in fatigue severity from baseline to 2-year follow-up were tested for an association with risk factors at baseline and with changes in symptoms other than fatigue during the follow-up period. RESULTS: The following characteristics at baseline significantly and independently predicted greater fatigue improvement: less unclear thinking, fewer somatoform symptoms not used to define chronic fatigue syndrome, infrequent awakening, fewer hours sleeping, and being married. Of 29 subjects who at baseline reported no somatoform symptoms unrelated to chronic fatigue syndrome and who thought clearly most of the time, 8 substantially improved, compared with 1 of 29 subjects who had more than 2 somatoform symptoms and never thought clearly (P = .01). Improvements in the following symptoms were significantly and independently associated with improvements in fatigue: unclear thinking, depression, muscle aches, and trouble falling asleep. CONCLUSIONS: This study identified characteristics of subjects that seem to be of prognostic importance for idiopathic chronic fatigue. Symptoms that change concomitantly with changes in fatigue may be intrinsically linked to fatigue.

Microcirculation architecture of metastases from primary ciliary body and choroidal melanomas.

PURPOSE: To describe the microcirculation architecture of metastatic choroidal and ciliary body melanoma. METHOD: Histologic sections of 35 metastases from 19 primary melanomas were stained to demonstrate microcirculation. RESULT: The appearance of microcirculatory networks in metastases is independent of the target organ but associated with the size of the metastatic deposit (estimated coefficient = 0.5959; SE = 0.3024; P = .0488). CONCLUSION: The microcirculatory patterns of primary uveal melanomas that are associated with metastatic behavior appear in foci of metastasis, regardless of the site of dissemination.

Outreach education to improve quality of rural ICU care. Results of a randomized trial.

This study tests whether an outreach educational program tailored to institutional specific patient care practices would improve the quality of care delivered to mechanically ventilated intensive care unit (ICU) patients in rural hospitals. The study was conducted as a randomized control trial using 20 rural Iowa hospitals as the unit of analysis. Twelve randomly selected hospitals received an outreach educational program. After review of the medical records of eligible patients, a multidisciplinary team of intensive care unit specialists from an academic medical center delivered an educational program with content specific to the findings and capacity of the hospital. The outcome measures included patient care processes, patient morbidity and mortality outcomes, and resource use. Results indicated that the outreach program significantly improved many patient care processes (lab work, nursing, dietary management, ventilator management, ventilator weaning). The program marginally reduced hospital ventilator days. Both total length of stay and ICU length of stay fell markedly in the intervention group (by an average of 3.2 and 2.1 d, respectively), while the control group fell only 0.6 and 0.3 d, respectively. However, these effects did not reach statistical significance. Unfortunately, the program had no detectable effects on the clinical outcomes of mortality or nosocomial events. We conclude that an outreach program of this type can effectively improve processes of care in rural ICUs. However, improving processes of care may not always translate into improvement of specific outcomes.

Relative importance of quantifying area and vascular patterns in uveal melanomas.

PURPOSE: To test whether the cross-sectional area of choroidal and ciliary body melanomas and quantification of microcirculatory networks and parallel vessels with cross-linking are features associated with death from metastatic melanoma, and to compare new with conventional histologic prognostic features. METHODS: The cross-sectional area of 234 ciliary body or choroidal melanomas was measured from digitized images of histologic sections. The percentage of cross-sectional area occupied by two microcirculatory patterns-networks and parallel vessels with cross-linking-was calculated for the 152 tumors containing at least one focus of either pattern. Kaplan-Meier survival curves were generated based on cross-sectional and percentage of cross-sectional areas of these patterns. Cox proportional hazard regression methods related time to death from melanoma with sets of predictor variables. For each model, percent variation explained was computed. RESULTS: Patient survival differs significantly when tumors are classified based on cross-sectional area: small (<16 mm2), medium (> or =16 mm2 but <61.4 mm2), and large (> or =61.4 mm2). Patients with tumors containing networks and parallel vessels with cross-linking microcirculation patterns that occupy 2% of cross-sectional area have a significantly worse prognosis than do those patients with tumors containing a smaller percentage of these patterns. CONCLUSIONS: Quantifying cross-sectional tumor area and the percentage area occupied by networks and parallel vessels with cross-linking microcirculatory patterns in ciliary body and cho. roidal melanomas provides significant prognostic information. Compared with more conventional prognostic characteristics, the most dramatic increase in prognostic information is provided by determination of the presence or absence of microvascular patterns.
