Abstract:

Background

Many clinics in Southern Africa have long waiting times. The implementation of point-of-care (POC) tests to accelerate diagnosis and improve clinical management in resource-limited settings may improve or worsen clinic flow and waiting times. The objective of this study was to describe clinic flow with special emphasis on the impact of POC testing at a large
urban public healthcare clinic in Durban, South Africa.

Methods

We used time and motion methods to directly observe patients and practitioners. We created patient flow maps and recorded individual patient waiting and consultation times for patients seeking STI, TB, or HIV care. We conducted semi-structured interviews with 20 clinic staff to ascertain staff opinions on clinic flow and POC test implementation.

Results

Among 121 observed patients, the total number of queues ranged from 4 to 7 and total visit times ranged from 0:14 (hours:minutes) to 7:38. Patients waited a mean of 2:05 for standard-of-care STI management, and approximately 4:56 for STI POC diagnostic testing. Stable HIV patients who collected antiretroviral therapy refills waited a mean of 2:42 in the standard queue and 2:26 in the fast-track queue. A rapid TB test on a small sample of patients with the Xpert MTB/RIF assay and treatment initiation took a mean of 6:56, and 40% of patients presenting with TB-related symptoms were asked to return for an additional clinic visit to obtain test results. For all groups, the mean clinical assessment time with a nurse
or physician was 7 to 9 min, which accounted for 2 to 6% of total visit time. Staff identified poor clinic flow and personnel shortages as areas of concern that may pose challenges to expanding POC tests in the current clinic environment.

Conclusions

This busy urban clinic had multiple patient queues, long clinical visits, and short clinical encounters. Although POC testing ensured patients received a diagnosis sooner, it more than doubled the time STI patients spent at the clinic and did not result in same-day diagnosis for all patients screened for TB. Further research on implementing POC testing efficiently into care pathways is required to make these promising assays a success.

Abstract:

Background

The science of implementation has offered little toward understanding how different implementation strategies work. To improve outcomes of implementation efforts, the field needs precise, testable theories that describe the causal pathways through which implementation strategies function. In this perspective piece, we describe a four-step approach to developing causal pathway models for implementation strategies.

Building causal models

First, it is important to ensure that implementation strategies are appropriately specified. Some strategies in published compilations are well defined but may not be specified in terms of its core component that can have a reliable and measureable impact. Second, linkages between strategies and mechanisms need to be generated. Existing compilations do not offer mechanisms by which strategies act, or the processes or events through which an implementation strategy operates to affect desired implementation outcomes. Third, it is critical to identify proximal and distal outcomes the strategy is theorized to impact, with the former being direct, measurable products of the strategy and the latter being one of eight implementation outcomes (1). Finally, articulating effect modifiers, like preconditions and moderators, allow for an understanding of where, when, and why strategies have an effect on outcomes of interest.

Future directions

We argue for greater precision in use of terms for factors implicated in implementation processes; development of guidelines for selecting research design and study plans that account for practical constructs and allow for the study of mechanisms; psychometrically strong and pragmatic measures of mechanisms; and more robust curation of evidence for knowledge transfer and use.

Excerpt:

Introduction

Children, defined as any boy or girl under 18 years, make up almost half of the world’s refugee population (United Nations High Commissioner for Refugees, 2016) and are exposed to challenges, traumas and stressors at the individual, family, and community levels that increase their risk for mental health problems (Barenbaum et al., 2004; Betancourt & Khan, 2008; Reed et al., 2012). These may include forced migration, forced labor, witnessing of murder and mass killings, lack of food and shelter, rape, torture, loss and separation from family, recruitment and use by armed forces, physical abuse, and family and sexual violence (Lustig et al., 2004; Office of the Special Representative of the Secretary-General for Children & Armed Conflict et al., 2009). Overlaid on potentially traumatic events are the daily, chronic stressors caused by displacement and associated with living in the camp environment – lack of basic needs, crowded and unsafe living conditions, and interpersonal conflict, among others (Layne et al., 2010; Miller & Rasmussen, 2010).

Children affected by these types of traumas and stressors present with a wide range of mental health symptoms, including those associated with posttraumatic stress (PTS), depression, anxiety, conduct problems, risk behaviors (e.g., alcohol or drug use), and distress associated with grief reactions (Barenbaum et al., 2004; Lustig et al., 2004; Sagi-Schwartz, 2008; Attanayake et al., 2009; Okello et al., 2013[for review], Morgos et al., 2008; Fernando et al., 2010; Miller & Rasmussen, 2010; Reed et al., 2012; Meyer et al., 2013; Newnham et al., 2015). Prevalence is difficult to study in these contexts; however, most studies find higher rates of mental health problems among displaced children compared with non-displaced populations (Goldstein et al., 1997; Paardekooper et al., 1999; Tousignant et al., 1999; Morgos et al., 2008; Bronstein & Montgomery, 2011; Reed et al., 2012).

There remains limited evidence on the effectiveness of interventions to treat mental health problems of children in refugee settings in low- and middle-income countries (LMICs). Some studies suggest that cognitive–behavioral-based treatments can be effective for reducing mental health symptoms in refugee children (Bolton et al., 2007; Layne et al., 2010). Relatedly, some eclectic psychosocial programs have been tested with conflict-affected populations, and show an impact on outcomes such as self-esteem or hope, but not mental health (Tol et al., 2014). Studies have generally utilized focal disorder treatments – or treatments focused on one disorder or cluster of symptoms. For example, Layne and colleagues used a treatment developed for posttraumatic stress disorder (PTSD) and grief (Layne et al., unpublished treatment manual) and Bolton and team (2007) used a treatment developed for depression (Interpersonal Therapy for depression; IPT). In contrast to this focal disorder treatment model where everyone receives the same elements in the same order, in common elements approaches providers learn elements that can be combined in different ways (elements used, order, dose) to treat a range of common mental health symptoms, and how to handle comorbidity (e.g., depression, trauma, anxiety co-occurrence) (Chorpita et al., 2005; Weisz et al., 2011; Weisz et al., 2012; Murray et al., 2014a). This approach is potentially more efficient and sustainable in both high-income countries (Mansell et al., 2008; Weisz et al., 2011; Weisz et al., 2012) and in LMICs (Bolton et al., 2014; Murray et al., 2014a; Ventevogel, 2015; Weisz et al., 2015) because it does not require providers to learn multiple interventions. Additionally, in settings with high rates of disorder comorbidity, such as in refugee populations, a model that can address multiple disorders may also be more appropriate (Murray & Jordans, 2016).

Current project

This paper reports on: (1) an evaluation of a common elements treatment approach (CETA) (Bolton et al., 2007; Bolton et al., 2014; Murray et al., 2014a; Weisz et al., 2015) developed for comorbid presentations of depression, anxiety, post traumatic stress, and/or externalizing symptoms among children in three Somali refugee camps on the Ethiopian/Somali border; and (2) an evaluation of implementation factors including acceptability, applicability/fit, feasibility and treatment facilitators, and barriers from the perspective of staff of the implementing partner organization, lay providers, and families who engaged in…
