The mechanics of implementation strategies and measures: advancing the study of implementation mechanisms.

BACKGROUND: There is a fundamental gap in understanding the causal mechanisms by which strategies for implementing evidence-based practices address local barriers to effective, appropriate service delivery. Until this gap is addressed, scientific knowledge and practical guidance about which implementation strategies to use in which contexts will remain elusive. This research project aims to identify plausible strategy-mechanism linkages, develop causal models for mechanism evaluation, produce measures needed to evaluate such linkages, and make these models, methods, and measures available in a user-friendly website. The specific aims are as follows: (1) build a database of strategy-mechanism linkages and associated causal pathway diagrams, (2) develop psychometrically strong, pragmatic measures of mechanisms, and (3) develop and disseminate a website of implementation mechanisms knowledge for use by diverse stakeholders. METHODS: For the first aim, a combination of qualitative inquiry, expert panel methods, and causal pathway diagramming will be used to identify and confirm plausible strategy-mechanism linkages and articulate moderators, preconditions, and proximal and distal outcomes associated with those linkages. For the second aim, rapid-cycle measure development and testing methods will be employed to create reliable, valid, pragmatic measures of six mechanisms of common strategies for which no high-quality measures exist. For the third aim, we will develop a user-friendly website and searchable database that incorporates user-centered design, disseminating the final product using social marketing principles. DISCUSSION: Once strategy-mechanism linkages are identified using this multi-method approach, implementation scientists can use the searchable database to develop tailored implementation strategies and generate more robust evidence about which strategies work best in which contexts. Moreover, practitioners will be better able to select implementation strategies to address their specific implementation problems. New horizons in implementation strategy development, optimization, evaluation, and deployment are expected to be more attainable as a result of this research, which will lead to enhanced implementation of evidence-based interventions for cancer control, and ultimately improvements in patient outcomes.

Rhesus isoimmunisation in unsensitised RhD-negative individuals seeking abortion at less than 12 weeks' gestation: a systematic review.

AIM: The aim of this review was to systematically review the outcome of routine anti-D administration among unsensitised rhesus (RhD)-negative individuals who have an abortion. This review is registered with Prospero. METHODS: A search for all published and ongoing studies, without restrictions on language or publication status, was performed using the following databases from their inception: EBM Reviews Ovid - Cochrane Central Register of Controlled Trials, MEDLINE Ovid (Epub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily), Embase.com, Popline and Google Scholar. Study types included: randomised controlled trials, controlled trials, cohort and case-control studies from 1971 onwards. The population included women who undergo an abortion (induced, incomplete, spontaneous or septic abortion), medical or surgical <12 weeks, and isoimmunisation in a subsequent pregnancy. The primary outcomes were: (1) development of a positive Kleihauer-Betke test and (2) development of Rh alloimmunisation in a subsequent pregnancy. RESULTS: A total of 2652 studies were screened with 105 accessed for full-text review. Two studies have been included with high bias appreciated. Both studies found few women to be sensitised in forming antibodies after an abortion. The limited studies available and heterogeneity prevent the conduction of a meta-analysis. CONCLUSIONS: Rh immunoglobulin has well-documented safety. However, it is not without risks and costs, is a possible barrier to delivering efficient services, and may have limited availability in some countries. The evidence base and quality of studies are currently limited. There is unclear benefit from the recommendation for Rh testing and immunoglobulin administration in early pregnancy. More research is needed as clinical practice guidelines are varied, based on expert opinions and moving away from testing and administration at time of abortion. IMPLICATIONS: There is limited evidence surrounding medical benefit of Rh testing and immunoglobulin administration in early pregnancy. Further research is needed to define alloimmunisation and immunoglobulin benefit to update standards of care. Additionally, other factors should be considered in forming clinical policies and guidelines such as costs, feasibility and impact on access to care for patients.

Dispensing and practice use patterns, facilitators and barriers for uptake of ulipristal acetate emergency contraception in British Columbia: a mixed-methods study.

BACKGROUND: Ulipristal acetate 30 mg became available as prescription-only emergency contraception in British Columbia, Canada, in September 2015, as an addition to over-the-counter levonorgestrel emergency contraception. In this study, we determined dispensing and practice use patterns for ulipristal acetate, as well as facilitators of and barriers to emergency contraception for physicians, pharmacists and patients in BC. METHODS: In the quantitative component of this mixed-methods study, we examined ulipristal acetate use from September 2015 to December 2018 using a database that captures all outpatient prescription dispensations in BC (PharmaNet) and another capturing market sales numbers for all oral emergency contraception in BC (IQVIA). We analyzed the quantitative data descriptively. We conducted semistructured interviews from August to November 2019, exploring barriers and facilitators affecting the use of ulipristal acetate. We performed iterative qualitative data collection and thematic analysis guided by Michie's Theoretical Domains Framework. RESULTS: Over the 3-year study period, 318 patients filled 368 prescriptions for ulipristal acetate. Use of this agent increased between 2015 and 2018. However, levonorgestrel use by sales (range 118 897-129 478 units/yr) was substantially higher than use of ulipristal acetate (range 128-389 units/yr). In the 39 interviews we conducted, from the perspectives of 12 patients, 12 community pharmacists, and 15 prescribers, we identified the following themes and respective theoretical domains as barriers to access: low awareness of ulipristal acetate (knowledge), beliefs and experiences related to shame and stigma (beliefs about consequences), and multiple health system barriers (reinforcement). INTERPRETATION: Use of ulipristal acetate in BC was low compared with use of levonorgestrel emergency contraception; lack of knowledge, beliefs about consequences and health system barriers may be important impediments to expanding use of ulipristal acetate. These findings illuminate potential factors to explain low use of this agent and point to the need for additional strategies to support implementation.

What Are the Clinical Factors That Are Predictive of Persistent Pessary Use at 12 Months?

OBJECTIVE: Urinary incontinence and pelvic organ prolapse are highly prevalent in women and have a significant impact on quality of life. Pessaries are devices that are used as a conservative management option. Many women use pessaries, which avoid surgical intervention with its associated morbidity and cost. However, not all women are good candidates for pessary use. The objective of this study was to determine clinical factors leading to persistent pessary use for incontinence or pelvic organ prolapse in a tertiary care centre at 12 months. Studying patient characteristics for long-term pessary use will contribute to better patient counselling, management, and health resource distribution. METHODS: This study was a retrospective outpatient chart review of new pessary fittings in patients in a tertiary care urogynaecology clinic between January and June 2014. Any woman over 18 years of age fitted with a pessary at that time was included in the study. All statistical analyses were performed using IBM SPSS Statistics version. 24 (IBM Corp., Armonk, NY) (Canadian Task Force Classification II-3). RESULTS: A total of 152 women were fitted with pessaries. A multivariable logistic regression analysis found that a patient's diagnosis of prolapse or incontinence (P = 0.01) and a lack of complications (P < 0.0001) were statistically significant for persistent pessary use at 12 months. Patients with prolapse had 7.7 times higher odds (95% CI 1.51-39.35) of using a pessary at 12 months than did patients with incontinence. Patients without complications had 250 times higher odds (95% CI 18.52-2500) of pessary use. Patients who tried two to three pessaries had 16 times higher odds (95% CI 1.80-137.00) of persistent use than patients who trialed just one. CONCLUSION: This study has found that a lack of complications, the number of pessaries tried, and a primary diagnosis of prolapse are significant factors for continued pessary use at 12 months.

Kuskaya: a training program for collaboration and innovation in global health.

To solve increasingly complex global health problems, health professionals must collaborate with professionals in non-health-related fields. The Universidad Peruana Cayetano Heredia and University of Washington created the NIH-funded Kuskaya training program in response to the need for transformative global health training for talented graduates from all disciplines. Kuskaya is a 1-year, interdisciplinary training program that teaches Peruvian and US graduates critical skills related to public health research through the design and implementation of a collaborative research project in Peru. Between 2014 and 2018, the program has trained 33 fellows, of which one third were from non-health disciplines. The program is unique because it targets junior trainees from disciplines outside of the health field, the program's curriculum is adapted to fit the fellows' backgrounds and professional aspirations, and the structure of the program allows for collaboration within the cohort and encourages fellows to apply for additional funding and pursue advanced degrees. Lessons learned in designing the Kuskaya program include: 1) involving mentors in the fellow selection process, 2) involving fellows in existing lines of research to increase mentor involvement, 3) institutionalizing mentoring through regular works-in-progress meetings and providing mentoring materials, and 4) defining a core curriculum for all fellows while providing additional supplementary materials to meet each cohort's needs, and evaluating their progress. Kuskaya provides an innovative model for bi-national, global health training to engage and provide a public health career pathway for all professionals.

A retrospective review of patients seen in a multidisciplinary pelvic floor clinic.

BACKGROUND: Multidisciplinary team care is becoming more popular for complex health issues, including pelvic floor dysfunction. METHODS: We conducted a retrospective review of the records of 207 patients attending a multidisciplinary pelvic floor dysfunction clinic. A telephone survey was also conducted. The outcomes investigated included conservative versus surgical management, comorbidities, number of specialists seen, and subjective patient feedback. RESULTS: The average patient was 59.9 years old and travelled an average distance of 128.6 km to attend the clinic. Common clinical presentations were urge urinary incontinence (58.9%) and stress urinary incontinence (54.6%). Ninety-three of 178 patients (52.2%) presented with at least two comorbidities. At the time of data collection, 52.2% of patients had opted for surgical management, 27.5% had chosen conservative management, and the remainder remained undecided. One hundred sixty-five women participated in the telephone survey and their responses were grouped into major themes: (1) wait times, (2) multidisciplinary clinic feedback, and (3) parking, patient education, and information distribution. CONCLUSION: Based on feedback, the majority of patients were accepting of a multidisciplinary approach to pelvic floor dysfunction and were satisfied with that approach.
