Pharmacogenetics testing (DPYD and UGT1A1) for fluoropyrimidine and irinotecan in routine clinical care: Perspectives of medical oncologists and oncology pharmacists.

BACKGROUND: Despite robust evidence and international guidelines, to support routine pharmacogenetic (PGx) testing, integration in practice has been limited. This study explored clinicians' views and experiences of pre-treatment DPYD and UGT1A1 gene testing and barriers to and enablers of routine clinical implementation. METHODS: A study-specific 17-question survey was emailed (01 February-12 April 2022) to clinicians from the Medical Oncology Group of Australia (MOGA), the Clinical Oncology Society of Australia (COSA) and International Society of Oncology Pharmacy Practitioners (ISOPP). Data were analysed and reported using descriptive statistics. RESULTS: Responses were collected from 156 clinicians (78% medical oncologists, 22% pharmacists). Median response rate of 8% (ranged from 6% to 24%) across all organisations. Only 21% routinely test for DPYD and 1% for UGT1A1. For patients undergoing curative/palliative intent treatments, clinicians reported intent to implement genotype-guided dosing by reducing FP dose for DPYD intermediate metabolisers (79%/94%), avoiding FP for DPYD poor metabolisers (68%/90%), and reducing irinotecan dose for UGT1A1 poor metabolisers (84%, palliative setting only). Barriers to implementation included: lack of financial reimbursements (82%) and perceived lengthy test turnaround time (76%). Most Clinicians identified a dedicated program coordinator, i.e., PGx pharmacist (74%) and availability of resources for education/training (74%) as enablers to implementation. CONCLUSION: PGx testing is not routinely practised despite robust evidence for its impact on clinical decision making in curative and palliative settings. Research data, education and implementation studies may overcome clinicians' hesitancy to follow guidelines, especially for curative intent treatments, and may overcome other identified barriers to routine clinical implementation.

Infective complications in cancer patients treated with subcutaneous versus intravenous trastuzumab and rituximab: An individual patient data meta-analysis.

BACKGROUND: Investigation of infection risk with subcutaneous versus intravenous trastuzumab and rituximab administration in an individual patient data (IPD) and published data meta-analysis of randomised controlled trials (RCTs). METHODS: Databases were searched to September 2021. Primary outcomes were serious and high-grade infection. Relative-risk (RR) and 95% confidence intervals (95%CI) were calculated using random-effects models. RESULTS: IPD meta-analysis (6 RCTs, 2971 participants, 2320 infections) demonstrated higher infection incidence with subcutaneous versus intravenous administration, without reaching statistical significance (serious: 12.2% versus 9.3%, RR 1.28, 95%CI 0.93to1.77, P = 0.13; high-grade: 12.2% versus 9.9%, RR 1.32, 95%CI 0.98to1.77, P = 0.07). With exclusion of an outlying study in post-hoc analysis, increased risks were statistically significant (serious: 13.1% versus 8.4%, RR 1.53, 95%CI 1.14to2.06, P = 0.01; high-grade: 13.2% versus 9.3%, RR 1.56, 95%CI 1.16to2.11, P < 0.01). Published data meta-analysis (8 RCTs, 3745 participants, 648 infections) demonstrated higher incidence of serious (HR 1.31, 95%CI 1.02to1.68, P = 0.04) and high-grade (HR 1.52, 95%CI 1.17to1.98, P < 0.01) infection with subcutaneous versus intravenous administration. CONCLUSIONS: Results suggest increased infection risk with subcutaneous versus intravenous administration, although IPD findings are sensitive to exclusion of one trial with inconsistent results and identified risk-of-bias. Ongoing trials may confirm findings. Clinical surveillance should be considered when switching to subcutaneous administration. PROSPERO registration CRD42020221866/CRD42020125376.

A systematic review and meta-analysis of toxicity and treatment outcomes with pharmacogenetic-guided dosing compared to standard of care BSA-based fluoropyrimidine dosing.

BACKGROUND: Serious and potentially life-threatening toxicities can occur following 5-fluorouracil/capecitabine exposure. Patients carrying Dihydropyrimidine Dehydrogenase (DPYD) variant alleles associated with decreased enzymatic function are at a greater risk of early/severe 5-fluorouracil/capecitabine toxicity. The objective of this systematic review/meta-analysis was to evaluate treatment outcomes between Pharmacogenetics Guided Dosing (PGD) versus non-PGD and within PGD (DPYD variant allele carriers versus wild type). METHODS: A systematic review/meta-analysis of original publications indexed in Ovid Medline, Ovid Embase, and the Cochrane CENTRAL (Wiley) library from inception to 7-Dec-2020. Eligible studies evaluated at least one pre-defined treatment outcome measures (toxicity/hospitalisations/survival/overall response/quality of life). RESULTS: Of 1090 identified publications, 17 met predefined eligibility criteria. The meta-analysis observed reduced incidence of grade 3/4 overall toxicity (Risk Ratio [RR] 0.32 [95% Cl 0.27-0.39], p < 0.00001) and grade 3/4 diarrhoea (RR 0.38 [95% Cl 0.24-0.61], p < 0.0001) among PGD versus non-PGD cohorts. Within PGD cohorts, there was no statistical differences for overall response rates (complete/partial) (RR 1.31 [95% Cl 0.93-1.85], p = 0.12). Similar results were found with stable disease (RR 1.27 [95% Cl 0.66-2.44], p = 0.47). CONCLUSION: PGD improves patient outcomes in terms of grade 3/4 toxicity, in particular overall toxicity and diarrhoea, without impacting on treatment response. REGISTRATION NUMBER: The study is registered with PROSPERO, registration number CRD42020223768.

A randomised controlled trial of clinical pharmacy intervention versus standard care to improve medication adherence in outpatients with head and neck cancer receiving radiotherapy.

PURPOSE: Patient understanding of medicines information and adherence to medication instructions are important variables for ensuring optimal cancer care. This randomised controlled trial (RCT) aimed to evaluate the impact of an outpatient clinical pharmacy service on medication adherence and symptom burden in cancer patients. METHODS: In this single-centre RCT, 115 patients were randomised 1:1 to a pharmacist-led pharmaceutical care program (intervention, n = 59) versus standard of care (control, n = 56) within an outpatient multidisciplinary radiotherapy clinic. The primary endpoint was medication adherence as assessed by Medication Understanding and Use Self-Efficacy (MUSE) scale and Teach-Back assessment. Secondary endpoints were patient-reported symptom burden assessed by the Edmonton Symptom Assessment Scale (ESAS). Patients were assessed at baseline (weeks 1-2) and at discharge from radiotherapy (weeks 5-7). RESULTS: Polypharmacy (use of five or more medications) was observed in 26% of patients at baseline compared to 97% at discharge. Patient self-efficacy and medication adherence was higher in the intervention arm compared to the control arm, with a mean MUSE score difference of 2.70 (95% CI 1.24, 4.17) after adjustment for baseline, and a higher proportion of patients with average Teach-Back score of four or more (86% vs 14%; odds ratio (OR) 46.09, 95% CI 14.49, 146.56). The mean (SD) scores for aggregate ESAS (0-100) at discharge were 26.2 (14.0) in the intervention arm and 32.0 (15.8) in the control arm demonstrating lower overall symptom burden associated with the intervention (mean score difference adjusted for baseline - 0.52; 95% CI - 1.03, - 0.01). CONCLUSION: A structured outpatient clinic pharmacy service significantly improved medication adherence and reduced overall symptom burden in patients receiving radiotherapy.

Radiation oncology outpatient medication management needs and service gaps - A cross-sectional study of patients and clinicians.

BACKGROUND: Patients receiving radiotherapy for the treatment of cancer can have complex medication requirements related to the management of side-effects and impaired swallowing ability. This study surveyed patients and clinicians to identify service gaps and unmet medication management needs. METHODS: Patient and clinician surveys were developed by a multidisciplinary team based on previously validated questionnaires. The patient survey focused on medication use and adherence. The clinician survey was based around a clinical case study and focused on identifying service gaps and practice variations. This survey was disseminated to radiation oncologists, pharmacists and nurses involved with the care of head and neck or lung cancer patients in Victoria. RESULTS: A total of 93 surveys were completed including 53 patient surveys and 40 clinician surveys. Radiotherapy patients reported high medication usage with up to 53% taking five or more medications daily. When asked the same set of questions relating to medication education requirements, patients receiving polypharmacy reported greater needs (72%) than recognised by the surveyed multidisciplinary clinician group (58%). They also reported a non-adherence rate of 46%. In addition, further disparities were identified in clinician practices and their approach to clinical situations which may result in conflicting advice and confusion for patients. CONCLUSION: While recognising deficiencies relating to the provision of medication information, oncologists, nurses and pharmacists underestimated patient needs for medication information, education and follow-up. Findings support the rationale for integration of pharmacy services within the radiotherapy clinics to support patient care and bridge service gaps relating to medication management.

A systematic review of the impact of outpatient clinical pharmacy services on medication-related outcomes in patients receiving anticancer therapies.

BACKGROUND: Patients receiving anticancer therapies are frequently prescribed complex and high-risk medication regimens, which at times can result in medication misadventures. The objective of this review was to assess the effect of outpatient clinical pharmacy services on medication-related outcomes in patients receiving anticancer therapies, including patients undergoing radiotherapy. METHODS: A systematic review of original publications indexed in EMBASE, MEDLINE and Cochrane Library from June 2007 to June 2017. Eligible studies evaluated outpatient pharmacy clinic services for cancer patients and reported at least one medication-related quantitative outcome measure. Two authors independently reviewed full-text articles for inclusion, then extracted data and performed quality and risk of bias assessments. RESULTS: Of 908 identified publications, 13 met predefined eligibility criteria; 1 randomised control trial, 2 controlled cohort studies and 10 uncontrolled before-after studies. Many excluded studies described outpatient pharmacy services but lacked medication-related outcomes. All included studies had informative practice model designs, with interventions for drug-related problems including drug dose optimisation ( n = 8), reduced drug interaction ( n = 6) and adverse drug reaction reporting ( n = 3). Most studies ( n = 11) reported on symptom improvement, commonly nausea ( n = 7) and pain ( n = 5). Of four studies in radiotherapy cohorts, pharmacist involvement was associated with improved symptoms, satisfaction and wellbeing scores. CONCLUSION: Few studies have objectively assessed outpatient pharmacy cancer services, even fewer in the radiotherapy settings. Although the results support these services, significant heterogeneity and bias in the study designs prohibit robust conclusions and further controlled trials are required.

Molecular diagnosis of Pneumocystis jirovecii in patients with malignancy: clinical significance of quantitative polymerase chain reaction.

Pneumocystis jirovecii pneumonia (PJP) is increasingly seen in association with the use of new and potent immunosuppressive therapies in populations not infected with human immunodeficiency virus. Today, molecular methods are widely used to improve diagnostic yield; however, the relationship between clinical findings and quantitative polymerase chain reaction (qPCR) results is undefined. Our objective was to describe characteristics of PJP in patients with malignancies and determine if qPCR results were correlated with clinical findings. From 2007 to 2012, all patients at the Peter MacCallum Cancer Centre with positive Pneumocystis PCR were identified from a microbiology database. Clinical, radiological, and microbiological records were reviewed. PJP was defined as the presence of positive PCR for Pneumocystis on a respiratory specimen, radiological abnormalities consistent with a pneumonic process, and receipt of targeted PJP treatment. qPCR was performed on all diagnostic specimens, and values were reported according to clinical findings. Forty-five patients fulfilled inclusion criteria: 44.4% had underlying solid organ tumors and 55.6% had hematological malignancies. Nonsmall cell lung carcinoma and lymphoma were the most frequent predispositions. Shortness of breath, cough, and fever were reported in 64.4%, 48.9%, and 42.2% of the patients, respectively. Admission to the intensive care unit and mortality rates were lower than in previous reports. Overall, a relationship between other clinical features and qPCR results was not identified. In the era of routine molecular diagnostics, patients with malignancy and PJP have improved outcomes. However, there was no demonstrable relationship between qPCR results and clinical features or PCR data and outcomes.

Utility of 30-Day Mortality Following Systemic Anti-Cancer Treatment as a Quality Indicator in Advanced Lung Cancer.

BACKGROUND: 30-day mortality after systemic anti-cancer therapy (SACT) has been suggested as a quality indicator primarily for measuring use of chemotherapy towards the end of life. Utility across different cancer types is unclear, especially when using immunotherapy and targeted therapies. METHODS: This retrospective study included patients with a diagnosis of lung cancer who received palliative-intent SACT at an Australian metropolitan cancer center between 2015 and 2022. Using a prospectively maintained lung cancer database, patient, disease, and treatment characteristics were evaluated against annual 30-day mortality rates following SACT. RESULTS: 1072 patients were identified. Annual 30-day mortality rate after palliative-intent SACT for lung cancer ranged between 9% and 15%, with significant variance between treatment types. Calculated rates of 30-day mortality are higher if longer reporting time periods are used. Patients who died within 30 days of SACT were more likely to have received targeted therapies or immunotherapy as their final line of treatment, have a poorer performance status at diagnosis, and have received multiple lines of treatment. CONCLUSIONS: Our data support differential interpretation of 30-day mortality for quality assurance, especially with regard to lung cancer. Consistency in population and reporting time periods, and accounting for treatment type is crucial if 30-day mortality is to be utilized as cancer care performance quality indicator. Relevance to quality care is questionable in the lung cancer setting.

A systematic review and meta-analysis of the impacts of germline pharmacogenomics on severe toxicity and symptom burden in adult patients with cancer.

The clinical application of Pharmacogenomics (PGx) has improved patient safety. However, comprehensive PGx testing has not been widely adopted in clinical practice, and significant opportunities exist to further optimize PGx in cancer care. This systematic review and meta-analysis aim to evaluate the safety outcomes of reported PGx-guided strategies (Analysis 1) and identify well-studied emerging pharmacogenomic variants that predict severe toxicity and symptom burden (Analysis 2) in patients with cancer. We searched MEDLINE, EMBASE, CENTRAL, clinicaltrials.gov, and International Clinical Trials Registry Platform from inception to January 2023 for clinical trials or comparative studies evaluating PGx strategies or unconfirmed pharmacogenomic variants. The primary outcomes were severe adverse events (SAE; ≥ grade 3) or symptom burden with pain and vomiting as defined by trial protocols and assessed by trial investigators. We calculated pooled overall relative risk (RR) and 95% confidence interval (95%CI) using random effects models. PROSPERO, registration number CRD42023421277. Of 6811 records screened, six studies were included for Analysis 1, 55 studies for Analysis 2. Meta-analysis 1 (five trials, 1892 participants) showed a lower absolute incidence of SAEs with PGx-guided strategies compared to usual therapy, 16.1% versus 34.0% (RR = 0.72, 95%CI 0.57-0.91, p = 0.006, I2 = 34%). Meta-analyses 2 identified nine medicine(class)-variant pairs of interest across the TYMS, ABCB1, UGT1A1, HLA-DRB1, and OPRM1 genes. Application of PGx significantly reduced rates of SAEs in patients with cancer. Emergent medicine-variant pairs herald further research into the expansion and optimization of PGx to improve systemic anti-cancer and supportive care medicine safety and efficacy.

Australian access to FDA-approved breakthrough therapy designation medicines: a 10-year review.

Background: Regulatory pathways adopted by the United States Food Drug and Administration (FDA) and Australian Therapeutic Goods Administration (TGA) enable expedited approval of medicines that are thought to offer significant clinical advantage over existing options for severe diseases. Objectives: To review Australian accessibility to medicines approved through the FDA breakthrough therapy designation (BTD) process including timelines and approvals by the TGA and Pharmaceutical Benefits Advisory Committee (PBAC) for listing on the Pharmaceutical Benefits Scheme (PBS). Methods: Retrospective review of published reports from the FDA, TGA, PBAC and PBS for BTDs from 1 January 2013-31 August 2023. Uniform data about BTD and milestone dates were collected. Analysis included all BTDs approved by FDA until 31-August-2022. Main outcome measures: Rates of approval by TGA and PBAC, and PBS-listing; and median (interquartile range, IQR) time from FDA submission to FDA approval, and FDA approval to TGA approval, PBAC approval and PBS listing for cancer and non-cancer medicines. Results: Of 237 BTDs across 156 medicines, 68% were approved by the TGA, and 37% were listed on the PBS. Median (IQR) time from FDA submission to FDA approval was shorter for cancer compared to non-cancer; 179 days (140-210) vs 232 days (181-245), p < 0.02. Time from FDA approval to PBS listing was similar for cancer and non-cancer; median 744 days (IQR, 549-1136) and 733 days (IQR 440-960) respectively, with improvements for cancer BTDs noted for 2018-2022 compared to 2013-2017; 566 days (IQR 319-831) vs 880 days (IQR 620-1362), p < 0.02 but not for non-cancer BTDs. Conclusion: BTD medicines are accessible in Australia approximately 2 years after FDA approval. Since 2018, time to PBS listing for cancer therapies improved, mirroring shorter FDA approval times for this category. Further understanding of clinical studies and context by therapeutic area may improve timely and safe access to life-saving medicines.

Late-onset Pneumocystis jirovecii pneumonia post-fludarabine, cyclophosphamide and rituximab: implications for prophylaxis.

OBJECTIVE: Fludarabine, cyclophosphamide and rituximab (FCR) therapy for lymphoid malignancies has historically been associated with a low reported incidence of Pneumocystis jirovecii pneumonia (PJP). However, prophylaxis was routinely used in early studies, and molecular diagnostic tools were not employed. The objective of this study was to review the incidence of PJP during and post-FCR in the era of highly sensitive molecular diagnostics and (18) F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-computerised tomography (CT). METHODS: All patients treated with standard FCR at the Peter MacCallum Cancer Centre (March 2009 to June 2012) were identified from a medications management database. Laboratory-confirmed PJP cases during this time were identified from an electronic database. RESULTS: Overall, 66 patients were treated with a median of 5.5 FCR cycles. Eight PJP cases were identified, 6 of whom had received chemotherapy prior to FCR. In 5 cases, (18) F-FDG PET demonstrated bilateral ground-glass infiltrates. Median CD4(+) lymphocyte counts at time of PJP diagnosis and 9-12 months following FCR were 123 and 400 cells/µL, respectively. In patients receiving no prophylaxis, 9.1% developed PJP during FCR. The rate following FCR was 18.4%, with median onset at 6 months (2.4-24 months). CONCLUSION: Given the high rate of late-onset PJP, consideration should be given for extended PJP prophylaxis for up to 12 months post-FCR, particularly in pretreated patients. Further evaluation of the role of CD4(+) monitoring is warranted to quantify risk of disease development and to guide duration of prophylaxis.

Rituximab for the treatment of follicular lymphoma.

Rituximab is the first and most widely adopted anti-CD20 monoclonal antibody, and has dramatically improved outcomes for patients with B-cell malignancies. Rituximab is active as a single agent and when combined with chemotherapy improves both response rates and survival compared with chemotherapy alone. This approach has become standard of care in this setting. A number of Phase III studies using extended applications of rituximab have demonstrated that patients achieve a significantly longer progression-free survival, at the cost of an increase in infective complications. This has resulted in the widespread adoption of maintenance rituximab following the completion of primary therapy. Rituximab is useful in both previously untreated patients and at relapse, although a subset of patients develop disease that is rituximab resistant, which along with histologic transformation remains a significant management problem for patients with follicular lymphoma. The toxicities are modest and manageable, including infusion reactions, late-onset neutropenia, impaired humoral immunity, reactivation of hepatitis and possibly pulmonary toxicity.

A controlled before and after study to evaluate a patient and health professional partnership model towards effective medication reconciliation.

UNLABELLED: Preventable medication errors impact substantially on the Australian healthcare system. Where 'poor communication of medical information at transition points is responsible for as many as 50% of all medication errors', a leading contributor for this type of medication error is lack of consumer knowledge about medicines information. This study was aimed at designing and testing the effectiveness of a consumer-healthcare professional partnership model towards effective medication reconciliation. This model aims to empower consumers about their medicines information, so that they would contribute more effectively to medication reconciliation and thereby minimise medication errors occurring at transition points. Components of this model were informed by qualitative data gleaned from patient opinion surveys, focus group sessions involving nurses, doctors and pharmacists working at the hospital and results of a literature search of medication safety tools. Programme development was informed by health improvement approaches centred on a Plan-Do-Study-Act cycle. Evaluation for effectiveness was conducted within a framework of a controlled before and after study. RESULTS: revealed that there was a 1.4-fold increase in the reporting rate of pharmacists intervention. The study could not demonstrate that the designed intervention was effective in minimising near-misses. However, there is statistically insignificant reduction in errors for patients that were correctly exposed to the intervention. Anecdotal evidence suggests there is utility for a patient population keen to claim greater ownership of their medicines information. Further, we advocate that patient education about medicines and the establishment of a consumer-healthcare professional model occur prior to ward admission.

Patient and healthcare professional acceptability of pharmacogenetic screening for DPYD and UGT1A1: A cross sectional survey.

This study explored the acceptability of a novel pharmacist-led pharmacogenetics (PGx) screening program among patients with cancer and healthcare professionals (HCPs) taking part in a multicenter clinical trial of PGx testing (PACIFIC-PGx ANZCTR:12621000251820). Medical oncologists, oncology pharmacists, and patients with cancer from across four sites (metropolitan/regional), took part in an observational, cross-sectional survey. Participants were recruited from the multicenter trial. Two study-specific surveys were developed to inform implementation strategies for scaled and sustainable translation into routine clinical care: one consisting of 21 questions targeting HCPs and one consisting of 17 questions targeting patients. Responses were collected from 24 HCPs and 288 patients. The 5-to-7-day PGx results turnaround time was acceptable to HCP (100%) and patients (69%). Most HCPs (92%) indicated that it was appropriate for the PGx clinical pharmacist to provide results to patients. Patients reported equal preference for receiving PGx results from a doctor/pharmacist. Patients and HCPs highly rated the pharmacist-led PGx service. HCPs were overall accepting of the program, with the majority (96%) willing to offer PGx testing to their patients beyond the trial. HCPs identified that lack of financial reimbursements (62%) and lack of infrastructure (38%) were the main reasons likely to prevent/slow the implementation of PGx screening program into routine clinical care. Survey data have shown overall acceptability from patients and HCPs participating in the PGx Program. Barriers to implementation of PGx testing in routine care have been identified, providing opportunity to develop targeted implementation strategies for scaled translation into routine practice.

A survey of reimbursement practices of private health insurance companies for pharmaceuticals not covered under the Pharmaceutical Benefits Scheme 2008.

OBJECTIVE: To describe the current practices and policy of Australian private health insurance (PHI) companies with respect to cover for pharmaceuticals not subsidised under the Pharmaceutical Benefits Scheme (PBS). DESIGN, SETTING AND PARTICIPANTS: A 2008 review of web-published policy statements for top-level hospital and comprehensive general treatment insurance, and survey of reimbursement practices by way of questionnaire, of 31 Australian-registered, open-membership PHI companies. MAIN OUTCOME MEASURES(S): Description of the level of pharmaceutical cover and important considerations identified by PHI companies for funding non-PBS pharmaceuticals through benefit entitlements or ex-gratia payments. RESULTS: Nine of thirty-one PHI companies (29%) provided responses accounting for ~60% market share of PHI. The majority of smaller PHI firms either declined participation or did not respond. The maximum limits offered for non-PBS pharmaceuticals, under comprehensive general treatment insurance, varied significantly and typically did not adequately cover high-cost pharmaceuticals. Some companies occasionally offered ex-gratia payments (or discretionary payments in excess of the policyholder's entitlement benefits) for high cost-pharmaceuticals. Factors considered important in their decision to approve or reject ex-gratia requests were provided. All results were de-identified. CONCLUSIONS: There is little consistency across PHI companies in the manner in which they handle requests for high-cost pharmaceuticals in excess of the defined benefit limits. Such information and processes are not transparent to consumers.

A cost analysis of febrile neutropenia management in Australia: ambulatory v. in-hospital treatment.

BACKGROUND: Adult febrile neutropenic oncology patients, at low risk of developing medical complications, may be effectively and safely managed in an ambulatory setting, provided they are appropriately selected and adequate supportive facilities and clinical services are available to monitor these patients and respond to any clinical deterioration. METHODS: A cost analysis was modelled using decision tree analysis, published cost and effectiveness parameters for ambulatory care strategies and data from the State of Victoria's hospital morbidity dataset. Two-way sensitivity analyses and Monte Carlo simulation were performed to evaluate the uncertainty of costs and outcomes associated with ambulatory care. RESULTS: The modelled cost analysis showed that cost savings for two ambulatory care strategies were ~30% compared to standard hospital care. The weighted average cost saving per episode of 'low-risk' febrile neutropenia using Strategy 1 (outpatient follow-up only) was 35% (range: 7-55%) and that for Strategy 2 (early discharge and outpatient follow-up) was 30% (range: 7-39%). Strategy 2 was more cost-effective than Strategy 1 and was deemed the more clinically favoured approach. CONCLUSION: This study outlines a cost structure for a safe and comprehensive ambulatory care program comprised of an early discharge pathway with outpatient follow-up, and promotes this as a cost effective approach to managing 'low-risk' febrile neutropenic patients.

Implementation of a whole of hospital sepsis clinical pathway in a cancer hospital: impact on sepsis management, outcomes and costs.

Infection and sepsis are common problems in cancer management affecting up to 45% of patients and are associated with significant morbidity, mortality and healthcare utilisation. OBJECTIVE: To develop and implement a whole of hospital clinical pathway for the management of sepsis (SP) in a specialised cancer hospital and to measure the impact on patient outcomes and healthcare utilisation. METHODS: A multidisciplinary sepsis working party was established. Process mapping of practices for recognition and management of sepsis was undertaken across all clinical areas. A clinical pathway document that supported nurse-initiated sepsis care, prompt antibiotic and fluid resuscitation was implemented. Process and outcome measures for patients with sepsis were collected preimplementation (April-December 2012), postimplementation cohorts (April-December 2013), and from January to December 2014. RESULTS: 323 patients were evaluated (111 preimplementation, 212 postimplementation). More patients with sepsis had lactate measured (75.0% vs 17.2%) and appropriate first dose antibiotic (90.1% vs 76.1%) (all p<0.05). Time to antibiotics was halved (55 vs 110 min, p<0.05). Patients with sepsis had lower rates of intensive care unit admission (17.1% vs 35.5%), postsepsis length of stay (7.5 vs 9.9 days), and sepsis-related mortality (5.0% vs 16.2%) (all p<0.05). Mean total hospital admission costs were lower in the SP cohort, with a significant difference in admission costs between historical and SP non-surgical groups of $A8363 (95% CI 81.02 to 16645.32, p=0.048) per patient on the pathway. A second cohort of 449 patients with sepsis from January to December 2014 demonstrated sustained improvement. CONCLUSIONS: The SP was associated with significant improvement in patient outcomes and reduced costs. The SP has been sustained since 2013, and has been successfully implemented in another hospital with further implementations underway in Victoria.

Pneumocystis jirovecii pneumonia associated with gemcitabine chemotherapy: experience at an Australian center and recommendations for targeted prophylaxis.

Pneumocystis jirovecii pneumonia (PJP) is seen increasingly in non-human immunodeficiency virus (HIV) infected immunocompromised populations, but few cases have previously been reported in association with gemcitabine therapy. We identified all patients administered gemcitabine between March 2009 and December 2012 at the Peter MacCallum Cancer Centre. Cases of PJP were identified using accepted definitions. Overall, 288 gemcitabine-treated patients were identified. Nine cases of PJP were detected, corresponding to an overall rate of 3.1% (95% confidence interval [CI] 1.5-5.7%). PJP was diagnosed during gemcitabine therapy in seven patients, a median of 67 (range 31-109) days from commencement. Among patients with lymphoma, 4/22 developed PJP, corresponding to a rate of 18.2% (95% CI 6.1-38.2%). Fewer infections were associated with breast, lung and gastrointestinal malignancies (1/24 [4.2%], 3/118 [2.5%] and 1/61 [1.6%], respectively). A risk-based tool incorporating concomitant steroid therapy can be applied to target high-risk populations who would benefit from PJP prophylaxis during gemcitabine therapy.
