Instrument and Supply Variability: An Opportunity to Reduce the Carbon Footprint of the Operating Room.

INTRODUCTION: Reducing costs and carbon footprints are important, parallel priorities for the US health-care system. Within surgery, reducing the number of instruments that are sterilized and disposable supplies that are used for each operation may help achieve both goals. We wanted to measure the existing variability in surgical instrument and supply choices and assess whether standardization could have a meaningful cost and environmental impact. METHODS: We analyzed surgeon preference cards for common general surgery operations at our hospital to measure the number of sterilizable instrument trays and supplies used by each surgeon for each operation. From this data, we calculated supply costs, carbon footprint, and median operative time and studied the variability in each of these metrics. RESULTS: Among the ten operations studied, variability in sterilizable instrument trays requested on surgeon preference cards ranged from one to eight. Variability in disposable supplies requested ranged from 17 to 45. Variability in open supply costs ranged from $104 to $4184. Variability in carbon footprint ranged from 17 to 708 kg CO2e. If the highest-cost surgeon for each operation switched their preference card to that of the median-cost surgeon, $245,343 in open supply costs and 41,708 kg CO2e could be saved. CONCLUSIONS: There is significant variability in the instrument and supply choices of surgeons performing common general surgery operations. Standardizing this variability may lead to meaningful cost savings and carbon footprint reduction, especially if scaled across the entire health system.

A case-case analysis of women with breast cancer: predictors of interval vs screen-detected cancer.

PURPOSE: The Breast Cancer Surveillance Consortium (BCSC) model is a widely used risk model that predicts 5- and 10-year risk of developing invasive breast cancer for healthy women aged 35-74 years. Women with high BCSC risk may also be at elevated risk to develop interval cancers, which present symptomatically in the year following a normal screening mammogram. We examined the association between high BCSC risk (defined as the top 2.5% by age) and breast cancers presenting as interval cancers. METHODS: We conducted a case-case analysis among women with breast cancer in which we compared the mode of detection and tumor characteristics of patients in the top 2.5% BCSC risk by age with age-matched (1:2) patients in the lower 97.5% risk. We constructed logistic regression models to estimate the odds ratio (OR) of presenting with interval cancers, and poor prognosis tumor features, between women from the top 2.5% and bottom 97.5% of BCSC risk. RESULTS: Our analysis included 113 breast cancer patients in the top 2.5% of risk for their age and 226 breast cancer patients in the lower 97.5% of risk. High-risk patients were more likely to have presented with an interval cancer within one year of a normal screening, OR 6.62 (95% CI 3.28-13.4, p < 0.001). These interval cancers were also more likely to be larger, node positive, and higher stage than the screen-detected cancers. CONCLUSION: Breast cancer patients in the top 2.5% of BCSC risk for their age were more likely to present with interval cancers. The BCSC model could be used to identify healthy women who may benefit from intensified screening.

Incorporation of Patient-Reported Outcomes Measurement Information System to assess quality of life among patients with breast cancer initiating care at an academic center.

BACKGROUND: Symptom burden and reduced quality of life (QOL) are considerable hurdles in oncology. The authors used the Patient-Reported Outcomes Measurement Information System (PROMIS), which assesses physical and psychosocial health, to establish a mean symptom burden, examine potential drivers, and characterize severe symptom burden in breast cancer patient subgroups with the goal of characterizing stage IV patient QOL and triaging patients to individualized supportive care services. METHODS: New patients at the University of California San Francisco Breast Care Center received questionnaires with 8 PROMIS domains: depression, anxiety, fatigue, sleep-related impairment, sleep disturbance, cognitive function, cognitive abilities, and physical function. PROMIS values were scored with the HealthMeasures service and were compared by age, cancer stage, and educational status. RESULTS: Stage IV patients with breast cancer (n = 169) reported higher depression and fatigue and worse cognitive function, cognitive abilities, and physical function than patients with stage 0 to III disease (n = 2577). As age increased, cognitive function impairment, depression, anxiety, and sleep-related symptoms decreased. More educated patients showed better physical function and less severe sleep disturbance and fatigue. Across all subgroups, patients with high anxiety had the greatest probability of worse symptom burden and function in other domains. CONCLUSIONS: This study provides an additional set of PROMIS population estimates across breast cancer demographic groups. The analysis of a large stage IV population reinforces that metastatic patients have impaired QOL across multiple domains. Because anxiety emerged as a potential driver of impaired QOL in other domains, earlier interventions to reduce anxiety could improve QOL overall. These analyses will help to determine appropriate thresholds of intervention. LAY SUMMARY: Patients receiving treatment for breast cancer can experience decreased quality of life. This study characterized differences in self-reported quality of life among patients of different ages, with different stages of cancer, and with different educational backgrounds. This study also examined the effect of decreased quality of life in one area (eg, anxiety) on another area (eg, difficulty in sleeping). Patients who were younger, had not attended college or technical school, or had stage IV cancer tended to have worse quality of life. Patients who had high levels of anxiety also tended to have high levels of impairment in other areas.

Evaluation of the Pathways for Survivors Program to Address Breast Cancer Survivorship-Associated Distress: Survey Study.

BACKGROUND: Patients with breast cancer frequently experience escalation of anxiety after completing curative treatment. OBJECTIVE: This study evaluated the acceptability and psychological impact of a 1-day workshop to emphasize behavioral strategies involving intention and self-efficacy. METHODS: Breast cancer survivors who attended a 1-day Pathways for Survivors workshop provided feedback and completed electronic quality of life (QOL) questionnaires at baseline, 1 and 6 weeks, and 6 months after the workshop. Attendees' baseline QOL scores were compared to follow-up (FUP) scores. Scores from patients receiving routine FUP care were also compiled as a reference population. RESULTS: In total, 77 patients attended 1 of 9 workshops. The mean satisfaction score was 9.7 out of 10 for the workshop and 9.96 out of 10 for the moderator. Participants' baseline mean Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression scores were 57.8 (SD 6.9) and 55.3 (SD 7.5), respectively, which were significantly higher than those of patients receiving routine FUP care (49.1, SD 8.3 and 47.3 SD 8.0, respectively). PROMIS anxiety and depression scores decreased, and the Happiness Index Profile (HIP-10) score-measuring intention and resiliency-increased significantly at 1- and 6-week FUPs. CONCLUSIONS: The Pathways for Survivors program was favorably received. Anxiety and depression decreased significantly at 1- and 6-weeks after the workshop and remained below baseline at 6 months. Increased HIP-10 scores suggest that patients acquired and implemented skills from the workshop. A 1-day workshop led by a lay moderator significantly improved several psychological measures, suggesting that it may be a useful and time-efficient strategy to improve QOL in breast cancer survivors. We are investigating whether an abbreviated "booster" of the intervention at a later date could further improve and maintain QOL gains.
