Lack of benefit in this study indicates that the CHW model
may be more effective when services are implemented at home. Knowing which specific strategies are most beneficial in terms of outcomes will help to further determine the most effective CHW models. HIF-1 cancer Regarding geography, 14 of the 16 studies in this review were conducted in four large American cities (Boston, Providence, New Haven and Los Angeles). As a result, it is possible that many of the subjects had been enrolled in other studies either concurrently or consecutively. The eligibility of study participants is often determined by specific inclusion criteria. This can limit the number of available subjects for study and also makes specific individuals particularly good research candidates. As a result, it is possible that subjects in our review were exposed to multiple interventions. Potential repeated exposure to HAART adherence
interventions could certainly influence the outcomes of the studies included in this review. A key component of the CHW model relies on building trust between participants and CHWs [19]. In our review, a short duration of intervention was associated with poorer outcomes, which may suggest that a longer Selleck Atezolizumab time is needed to establish a therapeutic bond. In addition to the length of intervention, the intensity, as specified by visits per week by CHWs, may also have an impact on outcomes. The effects of gradual de-escalation from daily to weekly
to maintenance are unknown. As cost-effectiveness is a concern with any health system intervention, it is important that studies explore this issue in the future. Effective maintenance processes may reduce the CHW’s daily burden of work with individual patients, thereby allowing more participants to receive services for a longer duration. This may also provide an effective structure for supporting participants to develop the skills required to adhere to HAART and to make the transition to independence. Balancing maintenance phase strategies to improve outcomes and minimize failures should be a focus of future research trials. The CHW model has been successfully implemented in many parts of the world, yet information regarding its efficacy in the USA is sparse. This review Methane monooxygenase highlights examples of successful programmes and explores deficiencies in others. Multicentred studies in diverse geographical locations are needed to further identify how health practitioners may utilize CHWs effectively. Recent health care reform legislation includes detailed information on CHWs and allocates funding for further CHW studies. Perhaps, with the passage of this legislation, the health care community will be able to begin work on such studies that may determine the most cost-effective way to deliver high-quality care.
