Use of the PARIHS Framework for Retrospective and Prospective Implementation Evaluations.

BACKGROUND: The Promoting Action on Research Implementation in Health Services (PARIHS) framework has been used by implementation researchers to assess factors impacting implementation and to use that information to identify optimal interventions and implementation strategies. In this paper, two studies are presented demonstrating the utility of PARIHS as a tool for retrospective and prospective evaluation of implementation in the health care setting. STUDY DESIGN: Descriptive case study. METHODS: A qualitative consensus process was used to evaluate provider perceptions of PARIHS constructs of evidence, context, and facilitation and their subelements which were scored on a continuum of low to high. RESULTS: The first example demonstrates retrospective use of PARIHS which provided insight into the factors contributing to variations in implementation across sites in an ongoing program. Evidence was strong (high), whereas context noted some challenges in culture and measurement (mixed), and the presence of dedicated program facilitators was positive but dual roles limited their ability to fully support implementation (mixed). The second example demonstrates prospective use of PARIHS for evaluation which gathered information about intervention sites for the purposes of selecting implementation strategies responsive to site needs. Evidence supporting the intervention was limited (low), context noted that limited awareness of the intervention was a challenge (low), and that a strong internal facilitator supported implementation (high). LINKING EVIDENCE TO ACTION: The descriptive case study presented here underscores the value of a theory-guided approach to implementation and highlights that PARIHS can help implementers understand factors impacting implementation, identify areas for future intervention, and inform selection of strategies to support or enhance implementation efforts.

Implementing an HIV Rapid Testing-Linkage-to-Care Project Among Homeless Individuals in Los Angeles County: A Collaborative Effort Between Federal, County, and City Government.

Objectives. We developed and implemented an HIV rapid testing-linkage-to-care initiative between federal and local government. Methods. We used mixed methodology; HIV testing data were collected on-site, and qualitative data were collected via telephone. We used postintervention stakeholder and staff interviews to evaluate barriers and facilitators to this initiative. Results. We tested 817 individuals. We identified and confirmed 7 preliminary HIV positive individuals (0.86% seropositivity), 5 of whom were linked to care. Mean testing cost was $48.95 per client; cost per positive result was $5714. Conclusions. This initiative can be used as a template for other health departments and research teams focusing on homelessness and mitigation of the HIV/AIDS epidemic.

HIV rapid testing in a Veterans Affairs hospital ED setting: a 5-year sustainability evaluation.

Routine HIV testing in primary care settings is now recommended in the United States. The US Department of Veterans Affairs (VA) has increased the number of patients tested for HIV, but overall HIV testing rates in VA remain low. A proven strategy for increasing such testing involves nurse-initiated HIV rapid testing (HIV RT). The purpose of this work was to use a mixed methodology approach to evaluate the 5-year sustainability of an intervention that implemented HIV RT in a VA emergency department setting in a large, urban VA medical center to reduce missed diagnostic and treatment opportunities in this vulnerable patient population. In-person semistructured interviews were conducted with providers and stakeholders. Interview notes were qualitatively coded for emerging themes. Quarterly testing rates were evaluated for a 5-year time span starting from the launch in July 2008. Findings indicate that HIV RT was sustained by the enthusiasm of 2 clinical champions who oversaw the registered nurses responsible for conducting the testing. The departure of the clinical champions was correlated with a substantial drop-off in testing. Findings also indicate potential strategies for improving sustainability including engaging senior leadership in the project, engaging line staff in the implementation planning from the start to increase ownership over the innovation, incorporating information into initial training explaining the importance of the innovation to quality patient care, providing ongoing training to maintain skills, and providing routine progress reports to staff to demonstrate the ongoing impact of their efforts.

The potential for health-related uses of mobile phones and internet with homeless veterans: results from a multisite survey.

BACKGROUND: Addressing the health needs of homeless veterans is a priority in the United States, and, although information technologies can potentially improve access to and engagement in care, little is known about this population's use of information technologies or their willingness to use technologies to communicate with healthcare providers and systems. MATERIALS AND METHODS: This study fills this gap through a survey of homeless veterans' use of information technologies and their attitudes about using these technologies to assist with accessing needed healthcare services. RESULTS: Among the 106 homeless veterans surveyed, 89% had a mobile phone (one-third were smartphones), and 76% used the Internet. Among those with a mobile phone, 71% used text messaging. Nearly all respondents (93%) were interested in receiving mobile phone reminders (text message or phone call) about upcoming medical appointments, and a similar proportion (88%) wanted mobile phone outreach asking if they would like to schedule an appointment if they had not been seen by a health provider in over a year. In addition, respondents already used these technologies for information and communication related to health, housing, and jobs. CONCLUSIONS: These findings suggest new avenues for communication and health interventions for hard-to-reach homeless veterans.

Implementation of nurse-initiated rapid HIV testing at high-prevalence primary care sites within the U.S. Veterans Affairs Health Care System.

Nurse-initiated HIV rapid testing (NRT) increases testing/receipt of results compared with traditional testing. We implemented NRT in primary care clinics at 2 Veterans Affairs hospitals.At site 1, 2364 tests were conducted; 5 HIV positives were identified. At site 2, 2522 tests were conducted; 9 HIV positives were identified. Success varied across demographic/clinical strata.

Budget impact analysis of HIV testing in the VA healthcare system.

OBJECTIVES: The long-term cost effectiveness of routine HIV testing is favorable relative to other medical interventions. Facility-specific costs of expanded HIV testing and care for newly identified patients, however, are less well defined. To aid in resource allocation decisions, we developed a spreadsheet-based budget-impact tool populated with estimates of facility-specific HIV testing and care costs incurred with an expanded testing program. METHODS: We modeled intervention effects on quarterly costs of antiretroviral therapy (ART), outpatient resource utilization, and staff expenditures in the Department of Veterans Affairs over a 2-year period of increasing HIV testing rates. We used HIV prevalence estimates, screening rates, counseling, positive tests, Veterans Affairs treatment, and published sources as inputs. We evaluated a single-facility cohort of 20,000 patients and at baseline assumed a serodiagnostic rate of 0.45%. RESULTS: Expanding testing from 2% to 15% annually identified 21 additional HIV-positive patients over 2 years at a cost of approximately $290,000, more than 60% of which was due to providing ART to newly diagnosed patients. While quarterly testing costs decreased longitudinally as fewer persons required testing, quarterly ART costs increased from $10,000 to more than $60,000 over 2 years as more infected patients were identified and started on ART. In sensitivity analyses, serodiagnostic and annual HIV testing rates had the greatest cost impact. CONCLUSIONS: Expanded HIV testing costs are greatest during initial implementation and predominantly due to ART for new patients. Cost determinations of expanded HIV testing provide an important tool for managers charged with allocating resources within integrated systems providing both HIV testing and care.

A provider participatory implementation model for HIV testing in an ED.

BACKGROUND: The Centers for Disease Control and Prevention recommends routine HIV screening for adults. OBJECTIVES: Community-based participatory research incorporates subjects in the design and conduct of research. We included nurses and physicians in the implementation of HIV rapid test use in the emergency department (ED). We explored the process, facilitators, and barriers. METHODS: We identified clinical champions and trained staff. Physicians obtained consent and ordered HIV testing; nurses performed rapid testing. Testing rates were tracked by electronic medical record. We conducted regular meetings between staff and researchers. Semistructured qualitative interviews with providers were conducted at 3 months. RESULTS: By week 15, we administered 121 tests. After the eligibility protocol evolved to incorporate ED nursing concerns regarding staffing limitations from a random sampling model to one focused on testing during nonpeak hours, the weekly number of tests increased. Eighteen percent of providers favored nontargeted HIV screening, 27% favored the current model of testing at nonpeak hours, 32% supported diagnostic testing, and 18% favored no testing or "other." Barriers include written consent, electronic documentation, time constraints, and belief that screening is not a core ED duty. Facilitators include ease of test administration, belief that ED patients are at higher risk, and flexibility to tailor screening efforts according to patient volume. CONCLUSIONS: The ED-based HIV testing is feasible within a Veterans Hospital Administration setting. Involvement of nursing in a community-based participatory research implementation model may facilitate staff acceptance of nontargeted HIV screening and be a mechanism to initiate administration of clinical preventive services to ED patients with limited primary care contact.

Exportability of an intervention to increase HIV testing in the Veterans Health Administration.

BACKGROUND: Exportability, or the dissemination of successful health services interventions from one site to another, must be demonstrated before systemwide implementation. METHODS: The effectiveness of a previously successful multicomponent intervention to increase rates of HIV testing in Veterans Health Administration (VHA) health care facilities among those without records of previous testing was evaluated in two other VHA facilities. Whereas the principle responsibility for the provider-activation component of the intervention was previously borne by research staff, nonresearch staff now took on these responsibilities. RESULTS: The annual rate of HIV testing among persons with documented risk factors for acquiring HIV infection increased by 5.8% and 16% after the end of the first year of implementation for the sites to which the project was newly exported and where nonresearch staff were responsible for implementation. In contrast, for the original implementation sites, where research staff played a major role in implementation, testing rates increased by 9.3% and 12.4%. There was no change in the rate of testing at a control site. At one site, HIV testing rates increased before implementation of the provider activation aspect of the intervention program. CONCLUSIONS: An intervention to increase HIV testing rates, which combines informatics, organizational support, and provider activation, can be successfully exported and implemented by nonresearch staff and may not require an extensive provider activation program. The resultant increases in HIV testing are similar to those seen in facilities where research staff play an active role. This work provides support for further efforts to refine this program to promote non-risk-based testing for HIV infection, as per current VHA policy and to more broadly implement this program.

Interactive internet-based clinical education: an efficient and cost-savings approach to point-of-care test training.

BACKGROUND: We successfully created and implemented an effective HIV rapid testing training and certification curriculum using traditional in-person training at multiple sites within the U.S. Department of Veterans Affairs (VA) Healthcare System. OBJECTIVE: Considering the multitude of geographically remote facilities in the nationwide VA system, coupled with the expansion of HIV diagnostics, we developed an alternate training method that is affordable, efficient, and effective. METHODS: Using materials initially developed for in-person HIV rapid test in-services, we used a distance learning model to offer this training via live audiovisual online technology to educate clinicians at a remote outpatient primary care VA facility. RESULTS: Participants' evaluation metrics showed that this form of remote education is equivalent to in-person training; additionally, HIV testing rates increased considerably in the months following this intervention. Although there is a one-time setup cost associated with this remote training protocol, there is potential cost savings associated with the point-of-care nurse manager's time productivity by using the Internet in-service learning module for teaching HIV rapid testing. If additional in-service training modules are developed into Internet-based format, there is the potential for additional cost savings. Our cost analysis demonstrates that the remote in-service method provides a more affordable and efficient alternative compared with in-person training. CONCLUSIONS: The online in-service provided training that was equivalent to in-person sessions based on first-hand supervisor observation, participant satisfaction surveys, and follow-up results. This method saves time and money, requires fewer personnel, and affords access to expert trainers regardless of geographic location. Further, it is generalizable to training beyond HIV rapid testing. Based on these consistent implementation successes, we plan to expand use of online training to include remote VA satellite facilities spanning several states for a variety of diagnostic devices. Ultimately, Internet-based training has the potential to provide "big city" quality of care to patients at remote (rural) clinics.

Cost-effectiveness of strategies to improve HIV testing and receipt of results: economic analysis of a randomized controlled trial.

BACKGROUND: The CDC recommends routine voluntary HIV testing of all patients 13-64 years of age. Despite this recommendation, HIV testing rates are low even among those at identifiable risk, and many patients do not return to receive their results. OBJECTIVE: To examine the costs and benefits of strategies to improve HIV testing and receipt of results. DESIGN: Cost-effectiveness analysis based on a Markov model. Acceptance of testing, return rates, and related costs were derived from a randomized trial of 251 patients; long-term costs and health outcomes were derived from the literature. SETTING/TARGET POPULATION: Primary-care patients with unknown HIV status. INTERVENTIONS: Comparison of three intervention models for HIV counseling and testing: Model A = traditional HIV counseling and testing; Model B = nurse-initiated routine screening with traditional HIV testing and counseling; Model C = nurse-initiated routine screening with rapid HIV testing and streamlined counseling. MAIN MEASURES: Life-years, quality-adjusted life-years (QALYs), costs and incremental cost-effectiveness. KEY RESULTS: Without consideration of the benefit from reduced HIV transmission, Model A resulted in per-patient lifetime discounted costs of $48,650 and benefits of 16.271 QALYs. Model B increased lifetime costs by $53 and benefits by 0.0013 QALYs (corresponding to 0.48 quality-adjusted life days). Model C cost $66 more than Model A with an increase of 0.0018 QALYs (0.66 quality-adjusted life days) and an incremental cost-effectiveness of $36,390/QALY. When we included the benefit from reduced HIV transmission, Model C cost $10,660/QALY relative to Model A. The cost-effectiveness of Model C was robust in sensitivity analyses. CONCLUSIONS: In a primary-care population, nurse-initiated routine screening with rapid HIV testing and streamlined counseling increased rates of testing and receipt of test results and was cost-effective compared with traditional HIV testing strategies.

The impact of integrated HIV care on patient health outcomes.

BACKGROUND: Control of viral replication through combination antiretroviral therapy (cART) improves patient health outcomes. Yet many HIV-infected patients have comorbidities that pose social and clinical barriers to achieving viral suppression. Integration of subspecialty services into HIV primary care may overcome such barriers. OBJECTIVE: To evaluate effect of integrated HIV care (IHC) on suppression of HIV replication. RESEARCH DESIGN: A retrospective cohort study of HIV patients from 5 Veterans Affairs healthcare facilities 2000 to 2006. SUBJECTS: Patients with >3 months of follow-up, sufficient baseline HIV severity, on cART. MEASURES: We measured and ranked Integrated Care at the facilities. These rankings were applied to patient visits to form an index of IHC utilization. We evaluated effect of IHC utilization on likelihood of achieving viral suppression while on cART, controlling for demographic and clinical factors using survival analysis. RESULTS: : The 1018 HIV-infected patients eligible for analysis had substantial barriers to responding to cART: 93% had comorbidities with mean 3.2 comorbidities per patient (SD = 2.0); 52% achieved viral suppression in median 231 days (SD = 411.6). Patients visiting clinics that offered hepatitis, psychiatric, psychologic, and social services in addition to HIV primary care were 3.1 times more likely to achieve viral suppression than patients visiting clinics which offered only HIV primary care (hazard ratio = 3.1, P < 0.001). CONCLUSIONS: Patients who visited IHC clinics were more likely to achieve viral suppression while on cART. Future research should investigate which elements of Integrated Care are most associated with viral control and what role provider experience plays in this association.

Evaluation of the sustainability of an intervention to increase HIV testing.

BACKGROUND: Sustainability-the routinization and institutionalization of processes that improve the quality of healthcare-is difficult to achieve and not often studied. OBJECTIVE: To evaluate the sustainability of increased rates of HIV testing after implementation of a multi-component intervention in two Veterans Health Administration healthcare systems. DESIGN: Quasi-experimental implementation study in which the effect of transferring responsibility to conduct the provider education component of the intervention from research to operational staff was assessed. PATIENTS: Persons receiving healthcare between 2005 and 2006 (intervention year) and 2006 and 2007 (sustainability year). MEASUREMENTS: Monthly HIV testing rate, stratified by frequency of clinic visits. RESULTS: The monthly adjusted testing rate increased from 2% at baseline to 6% at the end intervention year and then declined reaching 4% at the end of the sustainability year. However, the stratified, visit-specific testing rate for persons newly exposed to the intervention (i.e., having their first through third visits during the study period) increased throughout the intervention and sustainability years. Increases in the proportion of visits by patients who remained untested despite multiple, prior exposures to the intervention accounted for the aggregate attenuation of testing during the sustainability year. Overall, the percentage of patients who received an HIV test in the sustainability year was 11.6%, in the intervention year 11.1%, and in the pre-intervention year 5.0% CONCLUSIONS: Provider education combined with informatics and organizational support had a sustainable effect on HIV testing rates. The effect was most pronounced during patients' early contacts with the healthcare system.

Improving HIV screening and receipt of results by nurse-initiated streamlined counseling and rapid testing.

BACKGROUND: HIV testing is cost-effective in unselected general medical populations, yet testing rates among those at risk remain low, even among those with regular primary care. HIV rapid testing is effective in many healthcare settings, but scant research has been done within primary care settings or within the US Department of Veteran's Affairs Healthcare System. OBJECTIVES: We evaluated three methods proven effective in other diseases/settings: nurse standing orders for testing, streamlined counseling, and HIV rapid testing. DESIGN: Randomized, controlled trial with three intervention models: model A (traditional counseling/testing); model B (nurse-initiated screening, traditional counseling/testing); model C (nurse-initiated screening, streamlined counseling/rapid testing). PARTICIPANTS: Two hundred fifty-one patients with primary/urgent care appointments in two VA clinics in the same city (one large urban hospital, one freestanding outpatient clinic in a high HIV prevalence area). MEASUREMENTS: Rates of HIV testing and receipt of results; sexual risk reduction; HIV knowledge improvement. RESULTS: Testing rates were 40.2% (model A), 84.5% (model B), and 89.3% (model C; p = <.01). Test result receipt rates were 14.6% (model A), 31.0% (model B), 79.8% (model C; all p = <.01). Sexual risk reduction and knowledge improvement did not differ significantly between counseling methods. CONCLUSIONS: Streamlined counseling with rapid testing significantly increased testing and receipt rates over current practice without changes in risk behavior or posttest knowledge. Increased testing and receipt of results could lead to earlier disease identification, increased treatment, and reduced morbidity/mortality. Policymakers should consider streamlined counseling/rapid testing when implementing routine HIV testing into primary/urgent care.

A system-wide intervention to improve HIV testing in the Veterans Health Administration.

BACKGROUND: Although the benefits of identifying and treating asymptomatic HIV-infected individuals are firmly established, health care providers often miss opportunities to offer HIV-testing. OBJECTIVE: To evaluate whether a multi-component intervention increases the rate of HIV diagnostic testing. DESIGN: Pre- to post-quasi-experiment in 5 Veterans Health Administration facilities. Two facilities received the intervention; the other three facilities were controls. The intervention included a real-time electronic clinical reminder that encourages HIV testing, and feedback reports and a provider activation program. PATIENTS: Persons receiving health care between August 2004 and September 2006 who were at risk but had not been previously tested for HIV infection. MEASUREMENTS: Pre- to post-changes in the rates of HIV testing at the intervention and control facilities RESULTS: At the two intervention sites, the adjusted rate of testing increased from 4.8% to 10.8% and from 5.5% to 12.8% (both comparisons, p < .001). In addition, there were 15 new diagnoses of HIV in the pre-intervention year (0.46% of all tests) versus 30 new diagnoses in the post-intervention year (0.45% of all tests). No changes were observed at the control facilities. CONCLUSIONS: Use of clinical reminders and provider feedback, activation, and social marketing increased the frequency of HIV testing and the number of new HIV diagnoses. These findings support a multimodal approach toward achieving the Centers for Disease Control and Prevention's goal of having every American know their HIV status as a matter of routine clinical practice.

Expanding HIV rapid testing via point-of-care paraprofessionals.

HIV counselling and testing has traditionally been performed by highly trained professionals in clinical settings. With HIV rapid testing, a reliable and easy to use diagnostic tool, paraprofessionals can be trained to administer on-site HIV testing in a variety of non-traditional settings, broadening the HIV detection rates. Our objective was to create a robust and sustainable paraprofessional training module to facilitate off-site HIV rapid testing in non-clinical settings. Trainees attended a series of training sessions involving HIV education, rapid test instructions and communication techniques. After these sessions, trainees competently carried out HIV rapid testing in homeless shelters throughout the Los Angeles county. Agencies motivated to expand HIV screening programmes may use trained paraprofessionals to administer a full range of services (recruitment, pretest counselling, test administration, interpretation of results, post-test counselling and documentation) through this training model and enabling more highly trained healthcare providers to focus efforts on patients identified as HIV-positive.

An HIV collaborative in the VHA: do advanced HIT and one-day sessions change the collaborative experience?

BACKGROUND: Many organizations participate in quality collaboratives, yet the return on investment of the associated time and costs is unclear. METHOD: Semistructured interviews, surveys, and direct observation were used to assess experiences, improvement activities, and costs associated with participation in a year-long modified Institute for Healthcare Improvement-style collaborative designed to improve HIV care within the Veterans Health Administration. All nine sites had access to automated patient registries and semi-automated clinical measure reports; five sites also received computerized clinical reminders. Three one-day learning sessions were conducted. RESULTS: Participants reported that burden was small and value high, although many suggested that more time for peer-to peer learning would have been helpful. Teams averaged five quality improvement activities per site and most reported improvements in HIV care processes. The average annual cost per site was dollars 28,000 but costs varied considerably by site. DISCUSSION: Shortened learning sessions and the incorporation of health information technology can reduce some of the costs and burdens associated with collaboratives, yet peer-to-peer interaction and local organizational factors remain important to ensuring perceived effectiveness of collaboratives.

Efficacy of cannabinoids in fibromyalgia: a literature review / Eficacia de los cannabinoides en la fibromialgia: revisión de la literatura

Abstract Fibromyalgia is a chronic disease of unclear etiology, involving a neural oversensitization and impaired pain modulation, in addition to a clinical deficiency of the endocannabinoid system. Fibromyalgia is associated with a number of somatic and psychological disorders and hence multiple pharmacological approaches have been used, including opioids, antidepressants, antiepileptics, and more recently medical cannabis. This narrative review comprises a review of the current literature on the efficacy of cannabinoids in fibromyalgia. The studies describe a possible influence of cannabis on pain control in patients with fibromyalgia, with positive effects on quality of life and sleep. The use of cannabis seems to be beneficial in patients with fibromyalgia; however, more robust studies are still needed to establish is actual efficacy in pain management, quality of life and improvement of associated symptoms.

Resumen La fibromialgia es una enfermedad crónica, cuya etiología no es clara, en la que se involucra una sobresensibilización neural y disminución de la modulación del dolor, así como una deficiencia clínica del sistema endocannabinoide. Está asociada a una variedad de trastornos somáticos y psicológicos, por lo cual se han utilizado múltiples abordajes farmacológicos, entre ellos opioides, antidepresivos, antiepilépticos y, recientemente, cannabis medicinal. En esta revisión narrativa se hace una reseña de la literatura actual relacionada con la eficacia de los cannabinoides en la fibromialgia. Los estudios describen una posible influencia del cannabis sobre el control del dolor en pacientes con fibromialgia, con efectos positivos sobre la calidad de vida y el sueño. El uso del cannabis parece tener beneficios en los pacientes con fibromialgia; sin embargo, aún se requieren estudios más robustos para establecer su verdadera eficacia en el manejo del dolor, calidad de vida y mejoría de los síntomas asociados.

Organization and management of care for military veterans with human immunodeficiency virus/acquired immunodeficiency syndrome in Department of Veterans Affairs Medical Centers.

OBJECTIVE: As the largest provider of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome health care services, the Department of Veterans Affairs (VA) has launched a national quality improvement program. As a first step, an assessment of how care for veterans with HIV/acquired immunodeficiency syndrome was organized was conducted. METHODS: Structured surveys were administered to senior HIV clinicians in 118 VA facilities, about local approaches to structuring, staffing, and delivering HIV health services. RESULTS: HIV care was chiefly delivered in special VA-based HIV clinics. HIV-related services were widely available on site, with non-VA referrals being more commonly needed to meet long-term care needs. Urban VA facilities had greater HIV caseloads, were more likely to have separate HIV clinics, and had greater access to HIV expertise, whereas rural practices focused on primary care-based models and tended to rely on off-site VA HIV experts. CONCLUSIONS: Understanding the organization and management of VA-based HIV services will help design systematic quality improvement efforts and meet the treatment needs of HIV-infected veterans.

Differences among sexually abused and nonabused youth living with HIV.

Risk behaviors were compared between sexually abused and nonabused youth living with HIV (YLH). Abused YLH were significantly more likely to have attempted suicide, to have been admitted into an alcohol and/or drug treatment program, and to have engaged in crack cocaine use than were nonabused YLH and had a greater number of sexual partners. A significantly higher proportion of abused YLH had been incarcerated in contrast to nonabused youth. There were also significantly greater conduct problems among abused YLH. Finally, abused YLH had significantly higher scores on positive action and social-support coping styles than nonabused youth. Consistent with previous research, abused youth are at higher risk for a variety of negative outcomes and are also similar in many respects to sexually abused youth who are not HIV-positive. The high frequencies of two positive styles of coping among abused YLH were also observed.
