Decreasing opioid use in postoperative gynecologic oncology patients through a restrictive opioid prescribing algorithm.

OBJECTIVE: The objective of this study was to evaluate the impact of a post-surgical restrictive opioid prescribing algorithm (ROPA) in gynecologic oncology patients. METHODS: This cohort study included gynecologic oncology patients undergoing any surgical procedure from 08/2018-7/2019 after implementation of a ROPA. Patients were compared to historical controls managed without a ROPA from 10/2016-9/2017. Patients were educated preoperatively about pain management goals, the ROPA, and opioid disposal. A 4-tiered system was developed to standardize prescriptions at discharge based on surgical complexity and inpatient opioid requirements. Patients were surveyed at their postoperative visit to assess home opioid use and satisfaction. Statistical analysis was performed using SPSS Statistics v.24. RESULTS: 2549 patients met inclusion criteria; 1321 in the historical control group and 1228 in the ROPA group. Demographics, including age, BMI, and performance status were similar. Compared with the control group, the average number of opioid pills prescribed was significantly lower in the ROPA group (30.5 vs 11.3; p < 0.001) along with the morphine milligram equivalents (MME) (152.5 MME vs. 83.3 MME; p < 0.001). The percentage of patients requiring opioid refill within 30 days was similar (13.0% vs. 12.6%; p = 0.71). 95.7% of patients surveyed were satisfied with their pain regimen. The total number of pills prescribed annually decreased from 34,130 in the control group to 13,888 in the ROPA group. CONCLUSIONS: A restrictive prescribing practice allows for a significantly lower number of opioids to be prescribed to postoperative patients while maintaining patient satisfaction. There was no increase in opioid refill requests using a ROPA in patients undergoing surgery.

Experiences of mobility for people living with rheumatoid arthritis who are receiving biologic drug therapy: implications for podiatry services.

BACKGROUND: Despite significant advancements in new treatment modalities for rheumatoid arthritis with biological therapies, foot complications remain a disabling and common feature of the disease. In this study the aim was to explore and describe the personal experiences of people with rheumatoid arthritis in receipt of biologic treatments in a bid to understand the impact of this form of medication on their mobility. METHODS: An interpretative phenomenological analysis (IPA) was undertaken to explore in depth the individual experience of rheumatoid disease through personal accounts of the patient journey spanning both 'before' and 'after' the instigation of biologic therapy. A purposive sampling strategy was adopted and in-depth semi structured interviews used to facilitate rich, detailed interview data exploring the lived experiences of individuals undertaking biological therapy and the changes to mobility experienced as a result. Thematic analysis was employed with an IPA framework to identify key meanings, and report patterns within the data. RESULTS: Five people with rheumatoid arthritis participated in the study. The mean disease duration was 20.2 years (range: 6 -32) and all were being treated with biologic therapies. Four key themes emerged from the data: 1) Life before biologic treatment, depicted in accounts as a negative experience characterised by painful and disabling symptoms and feelings of hopelessness. 2) Life with biologic treatment, often experienced as a life changing transition, restoring function and mobility and offering renewed hope. 3) Sense of self, in which the impact of rheumatoid disease and the subsequent changes arising from biologic therapy reveal a profound impact on feelings of personal identity both pre and post biologic therapy; an effect of footwear on self-image emerges as a dominant sub theme; 4) Unmet footcare needs were evident in the patient narrative, where the unrelenting if diminished impact of foot pain on mobility was viewed in the context of problematic access to foot health services. CONCLUSION: Whilst the findings from this study mirror those within the existing literature, which report improvements in physical function related to biological therapy, foot problems clearly remained an unremitting feature of life for patients with rheumatoid disease, even when in receipt of biologics.

Reciprocal regulation of ß2-adrenoceptor-activated cAMP response-element binding protein signalling by arrestin2 and arrestin3.

Activation of Gs coupled receptors (e.g. ß2-adrenoreceptor (ß2AR)) expressed within the uterine muscle layer (myometrium), promotes intracellular cAMP generation, inducing muscle relaxation through short-term inhibition of contractile proteins, and longer-term modulation of cellular phenotype to promote quiescence. In the myometrium cAMP-driven modulation of cell phenotype is facilitated by CREB activity, however despite the importance of CREB signalling in the promotion of myometrial quiescence during pregnancy, little is currently known regarding the molecular mechanisms involved. Thus, we have characterised ß-adrenoceptor-stimulated CREB signalling in the immortalised ULTR human myometrial cell line. The non-selective ß-adrenoceptor agonist isoprenaline induced time- and concentration-dependent CREB phosphorylation, which was abolished by the ß2AR selective antagonist ICI118,551. ß2AR-stimulated CREB phosphorylation was mediated through a short-term PKA-dependent phase, and longer-term Src/p38 MAPK-dependent/PKA-independent phase. Since in model cells, arrestin2 can facilitate ß2AR-mediated Src/p38 recruitment, we examined whether CREB signalling was activated through a similar process in myometrial cells. Depletion of arrestin2 attenuated p38 phosphorylation, whilst arrestin3 depletion enhanced and prolonged isoprenaline-stimulated p38 signals, which was reversed following inhibition of Src. Knockdown of arrestin2 led to enhanced short-term (up to 10min), and attenuated longer-term (>10min) isoprenaline-stimulated CREB phosphorylation. Contrastingly, removal of arrestin3 enhanced and prolonged isoprenaline-stimulated CREB phosphorylation, whilst depletion of both arrestins abolished CREB signals at time points >5min. In summary, we have delineated the molecular mechanisms coupling ß2AR activity to CREB signalling in ULTR myometrial cells, revealing a biphasic activation process encompassing short-term PKA-dependent, and prolonged Src/arrestin2/p38-dependent components. Indeed, our data highlight a novel arrestin-mediated modulation of CREB signalling, suggesting a reciprocal relationship between arrestin2 and arrestin3, wherein recruitment of arrestin3 restricts the ability of ß2AR to activate prolonged CREB phosphorylation by precluding recruitment of an arrestin2/Src/p38 complex.
