Feasibility study of surveying the adverse drug reaction surveillance systems in a large community of hospitals.

OBJECTIVE: To determine the feasibility of accurately assessing the types of hospital adverse drug reaction (ADR) surveillance systems. DESIGN: Cross-sectional survey by mailed, self-administered questionnaire followed by selected verification interviews. SETTING: Harris County, Texas. PARTICIPANTS: All hospitals in the county with different pharmacy directors. MAIN OUTCOME MEASURE: Self description of surveillance system and number of ADRs reported. RESULTS: Forty-nine of 61 hospitals (80 percent) responded to a questionnaire. Forty-seven (96 percent) of the responding hospitals collected information on ADRs with 11 (22 percent) describing their surveillance system as active. Those individuals most often cited as responsible for ADR surveillance included pharmacists, quality assurance personnel, and nurses. Data were verified by personal interviews for 10 hospitals. The number of ADRs reported during the interviews was significantly lower than that reported in the questionnaires. Overall, the reporting of fatal and severe ADRs were more reliable than the reporting of moderate ADRs. These differences were the result of inadequate documentation and the lack of a uniform definition of ADRs. CONCLUSIONS: These data suggest that a large-scale ongoing survey of surveillance systems and reported adverse event rates has limitations and the reliability of data derived from a questionnaire should be verified. To improve the accuracy of surveys used to monitor hospital ADR surveillance systems, it is essential to develop reliable definitions for classifying ADRs and surveillance methods, as well as accurate measures of ADR documentation procedures.

Current treatment recommendations for leishmaniasis.

OBJECTIVE: To review the epidemiology, clinical presentation, risk factors for transmission, and pathogenesis of leishmaniasis, as well as current treatment options for this disease. DATA SOURCES/DATA SELECTION: We reviewed unclassified medical-threat briefing material, subject-matter reviews, and case reports from the world's infectious disease literature. We concentrated on literature pertaining to the pathogenesis and management of leishmaniasis indigenous to Southwest Asia. DATA EXTRACTION: Data from subject reviews published in the English language were evaluated. Case reports and clinical trials provided supplemental data on evolving theories and management options. DATA SYNTHESIS: The clinical presentation of leishmaniasis is highly variable. Management relies heavily upon the use of parenteral antimonial drugs. Although these agents are effective in most cases, toxicity and the emergence of resistance limit the usefulness of standard therapies. Alternative treatment modalities include heat, surgical curettage, ketoconazole, metronidazole, pentamidine, rifampin, amphotericin B, aminoglycosides, allopurinol, and immunotherapy. CONCLUSIONS: Although the number of reported cases of leishmaniasis in the US has generally been low, there is a possibility that more cases may be reported in the future because of the large number of military personnel returning to this country from endemic areas. Medical personnel, particularly those working in governmental institutions, should be familiar with the pathogenesis of this unusual infection as well as potential treatment options.

BCG and the treatment of superficial bladder cancer.

In this report, we review the evolution of bacillus Calmette-Guérin (BCG) immunotherapy as a legitimate form of treatment in superficial, nonmuscle-invasive bladder cancer. In the US, an estimated 45,000 new cases of bladder cancer are diagnosed each year and the annual death rate approaches 11,000. Approximately 70 percent of these cancers are superficial at the time of initial presentation. The treatment of superficial bladder cancer has three objectives: (1) eradication of existing disease, (2) prophylaxis against tumor recurrence, and (3) prevention of tumor progression (either muscular invasion, metastatic spread, or both). Cystectomy generally is reserved for muscle-invasive disease. Transurethral resection of the bladder tumor is the preferred initial therapy. Intravesical instillations of various chemotherapeutic agents following transurethral resection have been extensively investigated. Some of the common agents used include thiotepa, mitomycin, and doxorubicin. Despite such treatment efforts, however, over 40 percent of patients with superficial bladder cancer experience a recurrence of their tumor within three years. Approximately half of these recurrences either present as less-well-differentiated tumors or have already penetrated into the bladder musculature, metastasized, or both. Since Morales et al. first introduced intravesical BCG vaccine for prophylaxis as well as for treatment of superficial bladder tumors in 1976, support has grown rapidly for its use as an alternative to chemotherapy. When used with prophylactic intent following transurethral resection, recurrence rates are lower than those achieved with other agents. In addition, BCG is emerging as the consensus drug of choice for treating carcinoma in situ of the bladder. The mechanisms by which BCG exerts its antitumor activity remain largely unknown. BCG is thought to stimulate a localized, nonspecific inflammatory response that leads to subsequent shedding of tumor cells. A large body of clinical and experimental data suggest an association between the development of an immunologic response to BCG and successful antitumor activity. No universally accepted therapeutic regimen has been agreed upon. One regimen commonly used consists of an ampul of BCG mixed with 50 mL of NaCl 0.9%, instilled once a week for six weeks and retained for two hours prior to voiding. Maintenance therapy generally consists of intravesical doses given at three-month cycles for at least two years of recurrence-free follow-up. Because BCG is a biologic agent, the commercially available products may differ in weight, colony-forming units per vial, and antigenicity. How these product characteristics affect clinical responsiveness to different strains of BCG remains unanswered.

Possible intraoperative anesthetic-sparing effect of parenteral ketorolac.

OBJECTIVE: Because the analgesic effects of ketorolac are equivalent to those of narcotic analgesics, we investigated the possibility that this non-steroidal antiinflammatory drug might also exhibit anesthetic-sparing properties similar to those described for narcotic agents. DESIGN: A nonrandomized, double-blind convenience sample. The treatment group received a preoperative dose of ketorolac 60 mg im 45 minutes prior to the induction of anesthesia. All other preoperative medications were identical. SETTING: Brooke Army Medical Center, a primary care setting. PARTICIPANTS: Six women requiring vaginal hysterectomies from American Society of Anesthesiologists class I/II, all of similar age, weight, and body surface area. OUTCOME MEASURES: End-tidal concentrations of the anesthetic gas were measured at five-minute intervals using a gas analyzer. A mean percent end-tidal concentration versus time curve was generated for each group. RESULTS: The area under the concentration curves for the anesthetic gas in the ketorolac and control group were 15.9 +/- 5.1 and 52.3 +/- 13.4, respectively (p = 0.006). CONCLUSIONS: Ketorolac exhibits an anesthetic-sparing quality similar to that observed with narcotic analgesics.
