BACKGROUND: Hypertension is one of the most frequently diagnosed chronic medical conditions in the United States and imposes a substantial financial and social burden on Americans. OBJECTIVE: The aim of this study was to compare the cost of health care resources for hypertensive patients taking analgesics stratified by having controlled versus uncontrolled hypertension. METHODS: This was a retrospective, database analysis of data for managed-care patients in Maryland and Washington, DC, recorded from February 1, 1999, to July 31, 2001. Hypertensive patients who were taking analgesics were stratified by their hypertension control status using a claims-based algorithm. Annualized costs and differences in annualized costs calculated for the periods before and after the initiation of analgesics were compared by patient hypertension control status. RESULTS: Of the 9805 patients in the study (mean [SD] age, 49.8 [12.04] years), 2523 (25.73%) were categorized as having uncontrolled hypertension. The mean total annualized costs differed significantly between the controlled and uncontrolled hypertension groups by 2568 dollars (P < 0.001). The annualized costs for emergency-department visits and hospitalizations for uncontrolled hypertensive patients exceeded those for controlled hypertensive patients by 9.3% and 28.0%, respectively. The differences between the postindex- and preindex-period costs for health care resources were 1972 dollars with controlled hypertension and 2961 dollars with uncontrolled hypertension (P < 0.001). The results of linear regression, after adjustments were made for preindex costs and other covariates, indicated that patients with uncontrolled hypertension had significantly increased billed annualized costs (P < 0.001). CONCLUSIONS: These data suggest that the costs of health care resources were significantly higher for analgesic users with uncontrolled hypertension than for analgesic users with controlled hypertension. A considerable proportion of the cost differential was directly attributable to hypertension-related treatment care. 相似文献

To investigate the route of zoonotic transmission of HIV-1, we isolated three and seven HIV-1 strains from 449 Pygmy hunter gatherers and 169 neighboring Bantu, respectively, in southern Cameroon. Phylogenetic analysis based on pol-integrase and env-C2V3 sequences revealed that strains from Pygmies were 1CRF02_AG/CRF02_AG, 1 subtype G/CRF02 AG (pol/env), and 1 CRFll_cpx/CRF11_cpx, and that those from Bantu were 2 CRF02_AG/CRF02_AG, 1 CRF02_AG/CRF01_AE/A, 1 CRF02_AG/subtype A, 1 G/A, 1G/CRF02_AG, and 1 unclassified fH. CRF02_AG and CRF11_cpx have been identified in Cameroon. The results suggest that HIV-1 has been introduced into Pygmies through their neighboring Bantu rather than directly from nonhuman primates. 相似文献

OBJECTIVES: The aims of this study were to describe the characteristics surrounding female-to-female nonpartner violence and to identify independent factors associated with risk of female-to-female intentional injuries. METHODS: A case-control investigation was conducted among women who resided in an urban, low-income community and presented for emergency department care for injuries inflicted by female nonpartners. RESULTS: Women were typically victimized by women they knew (88%), in outdoor locations (60%), and in the presence of others (91%). Those found to be at risk for injury typically were young and socially active, used marijuana, and had experienced other kinds of violence. CONCLUSIONS: The present results showed that women injured by female nonpartners had limited resources, experienced disorder in their lives, and were the victims of violence within multiple relationships. 相似文献

PURPOSE: To determine the degree of pain and discomfort associated with transrectal sonography (TRS)-guided biopsy of the prostate and to analyze the complications associated with this procedure. METHODS: Three hundred men referred as part of an investigation to exclude prostate cancer were studied. The reasons for referral were suspected prostate cancer due to increased serum prostate-specific antigen level (>4 ng/ml), the finding of a palpable nodule or greater firmness of one prostatic lobe than the other on digital rectal examination, or the finding of a suspicious area of neoplasm of the prostate on TRS biopsy. All TRS-guided biopsies were performed as outpatient procedures without anesthesia. Ciprofloxacin prophylaxis was used in all patients before biopsy. Tolerance of the procedure was recorded immediately after the examination and graded on a scale of 0-4 as follows: 0, no pain; 1, very mild pain; 2, moderate pain; 3, severe pain; 4, intolerable pain. Complications recorded in the first week after the procedure were analyzed. They included mild pain, self-limiting hematuria, hematospermia, rectal bleeding, severe hematuria, septicemia, severe hemorrhage of the anus, and vasovagal attack. RESULTS: Out of 300 TRS-guided biopsies, 10 early complications were recorded. The most frequent was septicemia, which was seen in 5 cases (1.7%). Hematuria occurred in 29 patients, 3 of which were severe. Rectal bleeding and vasovagal attack occurred in 1 patient each. All patients made a full recovery with appropriate conservative management. Ten cases (3.33%) of severe pain (grade 3) and intolerable pain (grade 4) were observed. Three out of these 10 patients completed the procedure. The procedure was terminated in 1 patient, and 6 patients required local anesthetic due to perianal disease. CONCLUSIONS: TRS-guided prostate biopsy can be performed without local anesthesia in 90% of patients. Prophylactic antibiotics are mandatory to minimize approximately infectious complications. 相似文献
