Tracking implementation strategies in the randomized rollout of a Veterans Affairs national opioid risk management initiative.

BACKGROUND: In 2018, the Department of Veterans Affairs (VA) issued Notice 2018-08 requiring facilities to complete "case reviews" for Veterans identified in the Stratification Tool for Opioid Risk Mitigation (STORM) dashboard as high risk for adverse outcomes among patients prescribed opioids. Half of the facilities were randomly assigned to a Notice version including additional oversight. We evaluated implementation strategies used, whether strategies differed by randomization arm, and which strategies were associated with case review completion rates. METHODS: Facility points of contact completed a survey assessing their facility's use of 68 implementation strategies based on the Expert Recommendations for Implementing Change taxonomy. We collected respondent demographic information, facility-level characteristics, and case review completion rates (percentage of high-risk patients who received a case review). We used Kruskal-Wallis tests and negative binomial regression to assess strategy use and factors associated with case reviews. RESULTS: Contacts at 89 of 140 facilities completed the survey (64%) and reported using a median of 23 (IQR 16-31) strategies. The median case review completion rate was 71% (IQR 48-95%). Neither the number or types of strategies nor completion rates differed by randomization arm. The most common strategies were using the STORM dashboard (97%), working with local opinion leaders (80%), and recruiting local partners (80%). Characteristics associated with case review completion rates included respondents being ≤ 35 years old (incidence rate ratio, IRR 1.35, 95% CI 1.09-1.67) and having < 5 years in their primary role (IRR 1.23; 95% CI 1.01-1.51), and facilities having more prior academic detailing around pain and opioid safety (IRR 1.40, 95% CI 1.12-1.75). Controlling for these characteristics, implementation strategies associated with higher completion rates included (1) monitoring and adjusting practices (adjusted IRR (AIRR) 1.40, 95% CI 1.11-1.77), (2) identifying adaptations while maintaining core components (AIRR 1.28, 95% CI 1.03-1.60), (3) conducting initial training (AIRR 1.16, 95% CI 1.02-1.50), and (4) regularly sharing lessons learned (AIRR 1.32, 95% CI 1.09-1.59). CONCLUSIONS: In this national evaluation of strategies used to implement case reviews of patients at high risk of opioid-related adverse events, point of contact age and tenure in the current role, prior pain-related academic detailing at the facility, and four specific implementation strategies were associated with case review completion rates, while randomization to additional centralized oversight was not. TRIAL REGISTRATION: This project is registered at the ISRCTN Registry with number ISRCTN16012111. The trial was first registered on May 3, 2017.

Effect of a Positive Psychological Intervention on Pain and Functional Difficulty Among Adults With Osteoarthritis: A Randomized Clinical Trial.

Importance: Positive psychological interventions for improving health have received increasing attention recently. Evidence on the impact of such interventions on pain, and racial disparities in pain, is limited. Objective: To assess the effects of a positive psychological intervention on pain and functional difficulty in veterans with knee osteoarthritis. Design, Setting, and Participants: The Staying Positive With Arthritis Study is a large, double-blinded randomized clinical trial powered to detect race differences in self-reported pain in response to a positive psychological intervention compared with a neutral control intervention. Data were collected from 2 urban Veterans Affairs medical centers. Participants included non-Hispanic white and non-Hispanic African American patients aged 50 years or older with a diagnosis of osteoarthritis. Mailings were sent to 5111 patients meeting these criteria, of whom 839 were fully screened, 488 were eligible, and 360 were randomized. Enrollment lasted from July 8, 2015, to February 1, 2017, with follow-up through September 6, 2017. Interventions: The intervention comprised a 6-week series of evidence-based activities to build positive psychological skills (eg, gratitude and kindness). The control program comprised similarly structured neutral activities. Programs were delivered via workbook and weekly telephone calls with interventionists. Main Outcomes and Measures: The primary outcomes were self-reported pain and functional difficulty measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; range 0-100). Secondary outcomes included affect balance and life satisfaction. Results: The sample included 180 non-Hispanic white patients and 180 non-Hispanic African American patients (mean [SD] age, 64.2 [8.8] years; 76.4% were male). Mean (SD) baseline scores for WOMAC pain and functional difficulty were 48.8 (17.6) and 46.8 (18.1), respectively. Although both decreased significantly over time (pain: χ23 = 49.50, P < .001; functional difficulty: χ23 = 22.11, P < .001), differences were small and did not vary by treatment group or race. Exploratory analyses suggested that the intervention had counterintuitive effects on secondary outcomes. Conclusions and Relevance: The results of this randomized clinical trial do not support the use of positive psychological interventions as a stand-alone treatment for pain among white or African American veterans with knee osteoarthritis. Adaptations are needed to identify intervention components that resonate with this population, and the additive effect of incorporating positive psychological interventions into more comprehensive pain treatment regimens should be considered.

Rationale and design of the Staying Positive with Arthritis (SPA) Study: A randomized controlled trial testing the impact of a positive psychology intervention on racial disparities in pain.

Knee osteoarthritis is a painful, disabling condition that disproportionately affects African Americans. Existing arthritis treatments yield small to moderate improvements in pain and have not been effective at reducing racial disparities in the management of pain. The biopsychosocial model of pain and evidence from the positive psychology literature suggest that increasing positive psychological skills (e.g., gratitude, kindness) could improve pain and functioning and reduce disparities in osteoarthritis pain management. Activities to cultivate positive psychological skills have been developed and validated; however, they have not been tested in patients with osteoarthritis, their effects on racial differences in health outcomes have not been examined, and evidence of their effects on health outcomes in patients with other chronic illnesses is of limited quality. In this article we describe the rationale and design of Staying Positive with Arthritis (SPA) study, a randomized controlled trial in which 180 African American and 180 White primary care patients with chronic pain from knee osteoarthritis will be randomized to a 6-week program of either positive skill-building activities or neutral control activities. The primary outcomes will be self-reported pain and functioning as measured by the WOMAC Osteoarthritis Index. We will assess these primary outcomes and potential, exploratory psychosocial mediating variables at an in-person baseline visit and by telephone at 1, 3, and 6months following completion of the assigned program. If effective, the SPA program would be a novel, theoretically-informed psychosocial intervention to improve quality and equity of care in the management of chronic pain from osteoarthritis.

Antisecretory and antigastrin effects of rioprostil in gastric fistula dogs.

This investigation examined the effect of rioprostil, a primary alcohol prostaglandin E1 analog, on betazole-stimulated gastric acid secretion and on basal and food-stimulated (postprandial) serum gastrin levels in gastric fistula dogs. Rioprostil inhibited betazole-stimulated gastric acid secretion with an ED50 of 16 (10-24) micrograms/kg, intragastrically. A near-maximal gastric antisecretory dose (100 micrograms/kg, intragastrically) had no effect on basal serum gastrin levels but significantly attenuated the rapid rise in serum gastrin which follows feeding, a result different from that reported for other prostaglandin E1 analogs. A nonantisecretory dose of rioprostil (1.0 micrograms/kg, intragastrically) also attenuated the rise in postprandial serum gastrin. An antigastrin effect using a nonantisecretory dose of an antiulcer agent has not been reported previously and may indicate that rioprostil has a direct inhibitory effect on secretion of gastrin. The ability of rioprostil to inhibit gastric acid secretion and decrease postprandial peak serum gastrin levels, coupled with previously established cytoprotective efficacy, makes it an attractive clinical candidate for the treatment and prevention of peptic ulcer disease.

Altered susceptibility of arthritic rats to the gastric lesion-inducing effects of aspirin or ethanol and the antilesion effect of rioprostil.

It is well known that nonsteroidal antiinflammatory agents produce gastric mucosal lesions in both laboratory animals and man. However, the effect of an arthritic condition on their susceptibility to ulcerogenic agents and on the efficacy of antiulcer agents is less definitive. As a model to explore these questions, the effect of oral administration of aspirin or ethanol on gastric lesion formation was examined in rats with or without established adjuvant-induced polyarthritis. In addition, the antilesion efficacy of rioprostil, a primary alcohol prostaglandin E1 analog, was evaluated in both groups of rats. The results demonstrated that arthritic rats were more sensitive to the lesion-inducing effect of aspirin, but were more resistant to the lesion-inducing effect of ethanol when compared to normal rats. An increase in endogenous gastric prostaglandin production in arthritic rats may account for their relative resistance to ethanol. Aspirin inhibited the prostaglandin synthetic capacity of the stomach in both normal and arthritic rats, which may be responsible for eliminating the relative resistance of arthritic rats to gastric irritation. Rioprostil effectively prevented aspirin or ethanol-induced lesion formation in both arthritic and nonarthritic rats, but its potency against either irritant was decreased in arthritic rats.

Antigastrolesive, gastric antisecretory, diarrheagenic and mucus-stimulating effects in rats following topically applied rioprostil, a synthetic prostaglandin E1 analog.

Prostaglandins may have many biological actions including hypotensive and antipeptic ulcer activity. The purpose of this investigation was to determine if the primary alcohol prostaglandin E1 analog rioprostil1 prevents ethanol-induced gastric lesions (antigastrolesive activity), inhibits gastric acid secretion (antisecretory activity), or causes diarrhea in rats when administered topically, and to compare these responses to the effect of rioprostil following enteral (oral or intraduodenal) administration. Rioprostil exhibited antigastrolesive activity in rats when administered either orally or when applied topically. The topical antigastrolesive potency of rioprostil against ethanol-induced lesions [ED50 = 3.7 (0.5-12) micrograms/kg] was similar to its oral potency [ED50 = 1.9 (1.7-2.2) micrograms/kg]. In 4 hr pylorus-ligated rats, topically administered rioprostil inhibited total gastric acid output with a potency [ED50 = 5.1 (2.6-24) mg/kg] similar to intraduodenal administration [ED50 = 3.7 (2.8-5.3) mg/kg]. In addition, in these rats rioprostil increased mucin levels and did not cause dermal irritation. Finally, the incidence of diarrhea was lower when rioprostil was applied topically than when given orally with a 16-fold difference in potency between these two routes of administration. These data show that when rioprostil is applied via the skin it has antigastrolesive, gastric antisecretory and mucus stimulatory effects in rats equal to enteral administration, and a diarrheagenic potency lower than following oral administration. This profile suggests that topical administration of rioprostil may be a useful means of delivery for clinical treatment of peptic ulcer disease.

Rioprostil prevents gastric bleeding induced by nonsteroidal antiinflammatory drugs in dogs and arthritic rats.

Gastrointestinal irritation is the most significant side effect in patients chronically taking nonsteroidal antiinflammatory drugs (NSAID) for treatment of arthritic conditions. Rioprostil, a primary alcohol prostaglandin E1 analog, prevents gastric bleeding induced by several NSAID in a rat model of arthritis that is similar in many aspects to human rheumatoid arthritis. Daily oral dosing of rioprostil (50 micrograms/kg BID for 15 days) did not influence the course of the adjuvant disease in rats or alter the antiinflammatory or analgesic effect of the NSAID. In a 13 week efficacy study in dogs, rioprostil (40-60 micrograms/kg, PO) completely prevented gastric hemorrhagic lesions induced by daily administration of aspirin.

Antiulcer effect of rioprostil, a prostaglandin E1 analog, in combination with antacid.

Rioprostil, a primary alcohol prostaglandin E1 analog, is currently undergoing clinical evaluation for use in the treatment of peptic ulcer disease. Since antacids are often used in conjunction with other antiulcer agents, studies were conducted to determine if concomitantly administered antacid modifies the antiulcer activity of rioprostil. This investigation showed that concomitant administration of antacid (0.25-1.0 ml Maalox) does not inhibit the ability of rioprostil (0.125-4.0 micrograms/kg, p.o.) to prevent ethanol-induced gastric lesions in rats. The antiulcer effect of the drug combination was additive, suggesting that each compound acts independently to prevent gastric bleeding. These results in animals suggest that clinically the use of antacid will not compromise the efficacy of rioprostil and that the combination may be a useful mode of therapy for the treatment of peptic ulcer disease.
