Cost analysis of leukemia treatment: a problem-oriented approach.

A Problem Oriented List of Charges (POLC) can be used to obtain information about the cost of treatment of a single medical problem in patients with several coexisting medical problems. To prepare a POLC, each charge item is associated with one of the patient's problems. POLCs were compiled from the Problem Oriented Medical Records (POMRs) of patients with Acute Non-Lymphocytic Leukemic (ANLL). From the POLCs at was apparent that the treatment of granulocytopenia and thrombocytopenia and their sequelae were the most costly problems associated with ANLL. The projected cost of treatment for all problems for 11.5 months (the median survival of patients with ANLL treated with a single chemotherapeutic agent at this institution) was $40,022. By extending the POMR into the area of Medical reimbursement with a POLC, charge incurring activities can be coupled to the results of patient care. Only by directly coupling, in the original medical record, the reasons for, the charges for, and the results of medical care, can cost data be appropriately interpreted.

Ticarcillin in combination with cephalothin or gentamicin as empiric antibiotic therapy in granulocytopenic cancer patients.

Ticarcillin was used in combination with either cephalothin or gentamicin as initial empiric antibiotic therapy for 127 patient trials of suspected infection in granulocytopenic cancer patients. Bacteremia was present in 20%, nonbacteremic microbiologically documented infections in 21%, clinically documented infections in 23%, and possible infections in 5%; infection was doubtful in 31%. Although Staphylococcus aureus was the most common single organism isolated (23%), gram-negative bacilli accounted for 54% of all pathogens. Both antibiotic regimens were highly efficacious, with complete resolution in 46% of bacteremias, 88% of nonbacteremic microbiologically documented infections, and 95% of clinically documented infections. Among bacteremias, 8 of 9 caused by S. aureus but only 4 of 15 (27%) caused by gram-negative bacilli were completely resolved with these antibiotic combinations. Reasons for nonresponse in bacteremias were persistent granulocytopenia, mixed infection and, in two patients, antibiotic-resistant organisms. Toxicities other than hypokalemia were minimal. Although the rate of further infections was high overall (18/127), only one occurred among the 39 patients with <4 days of antibiotic therapy. Ticarcillin in combination with either cephalothin or gentamicin was effective as initial empiric therapy of suspected infection in granulocytopenic cancer patients.

Infection prevention in acute nonlymphocytic leukemia. Laminar air flow room reverse isolation with oral, nonabsorbable antibiotic prophylaxis.

Reverse isolation and prophylactic oral nonabsorbable antibiotics were evaluated among 64 consecutive noninfected adults with acute nonlymphocytic leukemia admitted for remission induction. Patients were randomly allocated to laminar air flow room reverse isolation with oral nonabsorbable antibiotics (LAF plus A), routine hospital ward care with antibiotics (W plus A), or ward care alone (W). The LAF plus A patients had a significantly decreased incidence of total infection, bacteremias, pneumonias, rectal abscesses, urinary tract infection, and pharyngitis. Infectious deaths were reduced in the LAF plus A group and the time to the first infection or to fatal infection was delayed. The W plus A patients who regularly ingested the antibiotics had a reduction in infections similar to that of the LAF plus A patients but those who could not tolerate the antibiotics had an incidence of infection comparable to the ward patients. The LAF plus A and the W plus A patients also had higher complete remission rates and longer median survival than the unprotected ward patients.

Fat emulsion vehicle for intravenous administration of an aqueous insoluble drug.

Formulation of a sterile preparation for the parenteral administration of a water insoluble drug is described. Methyl CCNU was first dissolved in absolute alcohol and slowly added to a fat emulsion, Intralipid. The preparation was found to be stable for eight hours at room temperature and seven days under refrigeration. After administration of the preparation to approximately 100 patients, no significant side effects were attributed to the fat emulsion.

Piperacillin sodium: antibacterial spectrum, pharmacokinetics, clinical efficacy, and adverse reactions.

Piperacillin sodium is a beta lactam antibiotic with a broad range of antibacterial activity that includes gram-negative bacilli, gram-positive cocci (except penicillinase-producing S. aureus) and anaerobic pathogens such as Clostridium difficile, and Bacteroides fragilis. Piperacillin inhibits many of the members of the Enterobacteriaceae, including Klebsiella sp and Pseudomonas, at lower concentrations than required for carbenicillin and ticarcillin. Piperacillin sodium is administered by intramuscular and intravenous injection and is widely distributed throughout body fluids and tissues. Like other newer penicillins, piperacillin is excreted by both renal and biliary mechanisms. The primary route of elimination is by glomerular filtration, which results in high urinary concentrations of the unchanged compound. Piperacillin has been approved for patients with serious infection caused by susceptible strains of specific organisms in intra-abdominal, urinary tract, gynecologic, lower respiratory tract, skin and skin structure, bone and joint, and gonococcal infections and septicemia. As with other penicillins, piperacillin has a low frequency of toxicity. The usual dose of piperacillin in adults with serious infections with normal renal function is 3-4 g every 4-6 hr as a 20-30 min infusion, with a maximum dose of 24 g per day. It is stable in most large volume parenteral solutions. Less serious infectins (requiring smaller dosages) may be treated by intramuscular injection; however, no more than 2 g should be given at any one injection site. Overall, piperacillin has a greater degree of activity than other penicillins. Evidence from prospective studies indicates that piperacillin is a highly effective agent for the treatment of patients with infections caused by susceptible organisms.

Review of amsacrine, an investigational antineoplastic agent.

The pharmacology, chemistry, pharmacokinetics, clinical studies, and adverse effects of amsacrine, an investigational antineoplastic agent, are reviewed. Amsacrine's mechanism of action is not clearly understood, although the drug is known to inhibit DNA synthesis. As an investigational NCI "Group C" agent, amsacrine is available to physicians for the treatment of adult patients with refractory acute nonlymphocytic leukemia (ANLL) under an established protocol. Following intravenous administration, amsacrine has a biphasic plasma clearance. It is extensively metabolized by the liver to inactive compounds that are excreted in the bile. Phase I studies indicated that amsacrine was potentially effective in patients with solid tumors and acute leukemias. Patients with solid tumors could tolerate much lower doses of amsacrine than leukemia patients because of dose-limiting bone-marrow suppression in the former. In Phase II studies, amsacrine appeared effective in treating the acute leukemias, with response rates of 31% and 23% for acute lymphocytic leukemia and ANLL, respectively. Patients with other types of cancers have not responded to amsacrine therapy. Frequently occurring adverse effects of amsacrine include leukopenia and thrombocytopenia in patients with solid tumors; nausea, vomiting, and diarrhea; mucositis in patients receiving higher doses (leukemia patients); alopecia; hepatotoxicity; and phlebitis. The clinical usefulness of amsacrine appears limited to treatment of the acute leukemias. Studies of combination therapies that include amsacrine are currently underway and should further define the therapeutic role of amsacrine.
