Chemotherapy-induced nausea and vomiting (CINV) and adherence to antiemetic guidelines: results of a survey of oncology nurses.

ABSTRACT:

Purpose

Chemotherapy-induced nausea and vomiting (CINV) can be prevented in most patients with use of guideline-recommended antiemetic regimens. However, studies have suggested that adherence to antiemetic guidelines is suboptimal. Oncology nurses, as part of a multidisciplinary team, can help promote appropriate antiemetic prophylaxis. Therefore, nurses were surveyed to assess antiemetic guideline awareness and practice patterns of antiemetic use, determine adherence to guideline recommendations, and query barriers to adherence.

Methods

In September 2015, 531 US-based oncology nurses participated in an online survey administered and analyzed by ONS:Edge.

Results

Nurses were most familiar with National Comprehensive Cancer Network (73%) and American Society of Clinical Oncology (48%) antiemetic guidelines. While most (77%) felt that antiemetics prescribed were consistent with guideline recommendations, practice patterns of antiemetic use revealed low adherence to those guidelines, particularly during the delayed (25-120 h) phase following highly emetogenic chemotherapy, where only 25% of nurses reported administration of guideline-recommended agents. Overutilization of phenothiazines and benzodiazepines was common. Only 17% of respondents reported that most (> 75%) of their patients have CINV optimally controlled; 39% reported between 6 and 20% of patients have an alteration in their chemotherapy due to CINV, and reports of emergency department/hospital visits due to poorly controlled CINV were high. The predominant barrier interfering guideline-recommended antiemetic prophylaxis was reported as physician preference (71%).

Conclusions

This survey revealed an opportunity to increase awareness of antiemetic guidelines and a critical need to address barriers interfering with utilization of guideline-recommended antiemetic agents in order to optimize CINV control for patients undergoing emetogenic chemotherapy.

Project description:Background Various predictive models have been developed which incorporates patient risk factors into the selection of optimal antiemetic therapy, one of which is chemotherapy-induced nausea and vomiting (CINV) risk scoring system developed by Multinational Association of Supportive Care in Cancer (MASCC). Patients and Methods Consecutive patients with gastrointestinal malignancy who had not received previous chemotherapy were eligible for enrollment in the study if they were scheduled to receive at least one cycle of chemotherapy. The CINV risk assessment tool was used to collect the study data and to assess CINV risk score. Results Ninety-eight patients fulfilling the eligibility criteria were included in this study, out of which 57% were males, median age was 48 years (range: 28-77). Colorectal cancer (32.7%) was the most common diagnosis followed by gastric cancer (27.6%). Gemcitabine/cisplatin and CAPOX regimen were the most common regimen being administered in 19.4% each. As per MASCC guidelines, 19.4% patients received highly emetogenic chemotherapy, 69.4% moderately emetogenic chemotherapy, while 11.2% received regimen with low emetogenicity. CINV risk module characterized 52% patients to have high risk for CINV, while 48% to have low risk of CINV, thus, 52% had the discrepancy in risk assigned by two methods, and this was statistically significant ( p = 0.025). In subgroup analysis, although patient cohort with acute nausea had no statistically significant discrepancy ( p = 0.123), but statistically significant discrepancy was found in patient cohort with delayed nausea ( p = 0.001), acute ( p = 0.038), and delayed ( p < 0.001) vomiting. Conclusion A significant percentage of patients who receive chemotherapy continue to experience nausea and vomiting despite receiving antiemetic treatment as per standard guidelines. The study generates a hypothesis for future large randomized studies looking at change in antiemetic prophylaxis based on CINV risk tool, leading to improvement in complete response rates of acute and delayed CINV.

Project description:Background:Co-administration of multiple antiemetics that inhibit several molecular pathways involved in emesis is required to optimize chemotherapy-induced nausea and vomiting (CINV) control in patients receiving highly emetogenic chemotherapy (HEC). NEPA, a fixed combination of a highly selective NK1 receptor antagonist, netupitant (300?mg), and the pharmacologically distinct 5-HT3RA, palonosetron (PALO 0.50?mg), has shown superior CINV prevention compared with PALO in cisplatin and anthracycline/cyclophosphamide-based settings. This study is the first head-to-head comparison of NEPA versus an aprepitant (APR)/granisetron (GRAN) regimen. Patients and methods:This randomized, double-blind phase III study conducted in Asia was designed with the primary objective to demonstrate non-inferiority of a single oral dose of NEPA compared with a 3-day oral APR/GRAN regimen in chemotherapy-naïve patients receiving cisplatin-based HEC. All patients also received oral dexamethasone (DEX) on days 1-4. The primary efficacy endpoint was complete response (CR: no emesis/no rescue medication) during the overall (0-120?h) phase. Non-inferiority was defined as a lower 95% CI greater than the non-inferiority margin set at?-?10%. Secondary efficacy endpoints included no emesis, no rescue medication, and no significant nausea (NSN). Results:Treatment groups were comparable for the 828 patients analyzed: predominantly male (71%); mean age 54.5?years; ECOG 0-1 (98%); lung cancer (58%). NEPA demonstrated non-inferiority to APR/GRAN for overall CR [NEPA 73.8% versus APR/GRAN 72.4%, 95% CI (-4.5%, 7.5%)]. No emesis [NEPA 75.0% versus APR/GRAN 74.0%, 95% CI (-4.8%, 6.9%)] and NSN rates [NEPA 75.7% versus APR/GRAN 70.4%, 95% CI (-0.6%, 11.4%)] were similar between groups, but significantly more NEPA patients did not take rescue medication [NEPA 96.6% versus APR/GRAN 93.5%, 95% CI (0.2%, 6.1%)]. NEPA was well tolerated with a similar safety profile to APR/GRAN. Conclusions:In this first study comparing NK1RA regimens and DEX, NEPA administered only on day 1 was non-inferior to a 3-day oral APR/GRAN regimen in preventing CINV associated with HEC.
