ABSTRACT
BACKGROUND: Recent changes in national reimbursement policies expand the ability of pharmacists to seek reimbursement for cognitive services. The quality of pharmacist-provided cognitive services has, until now, remained unassessed. Pharmacists should demonstrate the quality and value of their work to ensure the continued and expanded acceptance of reimbursement for their services. A preliminary step in assessing quality is to compare agreement between pharmacists for basic problem identification. OBJECTIVE: To quantify agreement between pharmacist reviewers for problem identification among Utah Medicaid recipients. METHODS: Five pharmacists retrospectively reviewed drug regimens, patient characteristics, diagnosis codes, and procedures for 80 Medicaid patients in September 2008 and identified drug-related problems (DRPs) in 15 predetermined categories. Data for each patient were reviewed twice, and each combination of 2 pharmacists reviewed the same 8 patients' information. We calculated a reliability coefficient to compare the number of DRPs identified and used prevalence and bias adjusted kappa (PABAK) to determine interrater reliability for the presence of a specific DRP. RESULTS: Of the 15 DRPs categorized by pharmacist reviewers, 1 (untreated indications) had a PABAK coefficient of 0.20, indicating a relatively low level of agreement between reviewers. All other DRP categories had good to excellent agreement, with PABAK coefficients ranging between 0.43 and 0.98. CONCLUSIONS: Pharmacist reviewers exhibited less variability in DRP identification or categorization than had been expected for most categories. This work supports the conclusion that pharmacists in our center provide a basic and necessary level of quality for problem assessment. Future work is needed to document the impact of this quality on patient outcomes.

Polymethylmethacrylate bone cement beads impregnated with antibiotic are a common treatment for patients with persistent articular joint infections or osteomyelitis. They also are used as a prophylaxis for infection in patients with large soft tissue wounds. The current study was designed to evaluate the relationship between bead geometry and elution of the antibiotic tobramycin by methodically varying the shape of the beads for a given set of volumes. Beads of five shapes (spherical to ovoid) and two volumes were prepared and studied. Only 0.9% to 3.3% of the total amount of tobramycin present actually eluted from the beads in a 96-hour period and of this amount, approximately 1/3 eluted within the first 4 hours. The elution mass data indicate the benefit of numerous, small and elliptically shaped beads for maximal antibiotic availability. Additionally, a mathematical model is presented that describes these findings and can be used to predict tobramycin delivery rates from bone cement beads. This model assumes that the antibiotic is delivered through two mechanisms: fast dissolution of tobramycin initially adhering to the bead surface and slow release by diffusion through the polymer. The results generate diffusion coefficients for tobramycin in polymethylmethacrylate bone cement on the order of 2 x 10 cm/s.

Data from short- and long-term follow-up studies indicate that thigh pain is a significant complication after apparently successful cementless total hip arthroplasty. In most cases, reported symptoms are mild to moderate, resolve spontaneously or do not progress, and require little or no therapeutic intervention. However, persistent thigh pain may be a source of dissatisfaction or may present as severe, disabling pain. Possible causes include bone-prosthesis micromotion, excessive stress transfer to the femur, periosteal irritation, or a mismatch in Young's modulus of elasticity that increases the structural rigidity of the prosthetic stem relative to the femur. Thorough diagnostic evaluation of thigh pain is essential to rule out prosthetic infection or loosening, stress fracture, or spinal pathology as the primary source. Treatment options in the aseptic, well-fixed femoral component include medical management, revision of the femoral component, or cortical strut grafting at the tip of the implant.

A case report and discussion of a 64-year-old white female who presented with uncontrolled pain in several body areas despite massive oral controlled release morphine use is presented. Her pain was not associated with much spasticity. This patient responded remarkably to intrathecal baclofen even after the opioid was tapered and discontinued. The potential usefulness of baclofen in seemingly opioid-resistant chronic pain is discussed.

Patients are now able to obtain mail order prescriptions through the Internet from reputable online pharmacies without leaving their home. While this can be a great convenience, the Internet also provides a new means for easily questionable or even illegal prescription medications, i.e., prescription legend medications may be obtained without a prescription and drug products not legally available in the United States can be obtained in this way. Many chronic pain patients are drug seeking, and increasingly many are using the Internet to learn about medications, and perhaps to obtain them. Clinicians should know where their patients obtain medications, how to verify the validity of the sources of prescriptions, and how to report fraud. Ways to verify the legitimacy of an online pharmacy are described.
