Evaluation and optimization of a clinical pharmacist driven transitions of care model for malignant hematology.

PURPOSE: To implement and optimize a pilot transitions of care model for scheduled chemotherapy admissions in patients with hematologic malignancies at our institution.Methodology: We utilized the plan-do-study-act (PDSA) quality improvement technique to prospectively measure success of interventions related to improving transitions of care processes that occurred in multiple stages including development of standardized operating procedures, electronic medical record documentation, and education to the malignant hematology multidisciplinary group. Chart review was performed retrospectively for at least nine patients per PDSA cycle. Areas of intervention addressed and measured regarding communication between the ambulatory care and acute care settings included: admission purpose, processes related to insurance benefits investigations for specialty medications required in the post-discharge setting, and plan for growth factors, prophylactic antimicrobials, and follow-up.Results and conclusions: We included 28 patients and performed a total of three PDSA cycles demonstrating specific improvements in: communication regarding status of benefits investigations performed for specialty medications prior to admission, resolution of these benefits investigations at various time points, improvement in efficient use of the electronic medical record for chemotherapy orders, and patient instructions for appropriate use of prophylactic antimicrobials. Although improvement was noted initially with prescribing of discharge antiemetics and antimicrobials, regression to baseline was noted with the third PDSA cycle.

Evaluation of thiamine for the prevention of ifosfamide-induced encephalopathy.

STUDY OBJECTIVE: To determine whether thiamine prophylaxis decreases the incidence of ifosfamide-induced encephalopathy in patients receiving ifosfamide for the treatment of lymphoma. DESIGN: Retrospective, multi-center, cohort study. PATIENTS: A total of 73 patients who received 187 total cycles of ifosfamide, carboplatin, and etoposide chemotherapy for the treatment of lymphoma were included in this study. Forty-four of these patients (114 cycles) were included in the no-thiamine group and 29 (65 cycles) in the thiamine group. MEASUREMENTS AND MAIN RESULTS: The incidence of ifosfamide-induced encephalopathy was measured using the Common Terminology Criteria for Adverse Events and documentation in the patient chart. Regarding the primary endpoint of ifosfamide-induced encephalopathy, eight patients (18.2%) in the no-thiamine group and three patients (10.3%) in the thiamine group experienced an event (p = 0.5087). No patient experienced more than one neurotoxic event. CONCLUSION: There was no significant difference found in the incidence of ifosfamide-induced encephalopathy with the addition of thiamine prophylaxis in patients receiving ifosfamide, carboplatin, and etoposide-based chemotherapy regimens for lymphoma. Larger, prospective studies assessing the use of thiamine prophylaxis in this patient population are warranted to better assess its impact on the incidence of ifosfamide-induced encephalopathy.

Rates of Renal Toxicity in Cancer Patients Receiving Cisplatin With and Without Mannitol.

BACKGROUND: Cisplatin is a widely used antineoplastic. One of the major complications of cisplatin use is dose-limiting nephrotoxicity. There are many strategies to prevent this toxicity, including the use of mannitol as a nephroprotectant in combination with hydration. OBJECTIVE: We aimed to evaluate the rates of cisplatin-induced nephrotoxicity in cancer patients receiving single-agent cisplatin with and without mannitol. METHODS: This single-center retrospective analysis was a quasi experiment created by the national mannitol shortage. Data were collected on adult cancer patients receiving single-agent cisplatin as an outpatient from January 2011 to September 2012. The primary outcome was acute kidney injury (AKI). RESULTS: We evaluated 143 patients who received single-agent cisplatin; 97.2% of patients had head and neck cancer as their primary malignancy. Patients who did not receive mannitol were more likely to develop nephrotoxicity: odds ratio [OR] = 2.646 (95% CI = 1.008, 6.944; P = 0.048). Patients who received the 100 mg/m2 dosing and patients who had a history of hypertension also had a higher likelihood of developing nephrotoxicity: OR = 11.494 (95% CI = 4.149, 32.258; P < 0.0001) and OR = 3.219 (95% CI = 1.228, 8.439; P = 0.017), respectively. CONCLUSIONS: When limited quantities of mannitol are available, it should preferentially be given to patients at particularly high risk of nephrotoxicity. Our analysis suggests that those patients receiving the dosing schedule of 100 mg/m2 cisplatin every 3 weeks and those with hypertension are at the greatest risk of nephrotoxicity and would benefit from the addition of mannitol.
