Understanding the factors that influence CT utilization for mild traumatic brain injury in a low resource setting - a qualitative study using the Theoretical Domains Framework.

Introduction: In low resource settings (LRS), utilization of Computed Tomography scan (CTS) for mild traumatic brain injuries (mTBIs) presents unique challenges and considerations given the limited infrastructure, financial resources, and trained personnel. The Theoretical Domains Framework (TDF) offers a comprehensive theoretical lens to explore factors influencing the decision-making to order CTS for mTBI by imaging referrers (IRs). Objectives: The primary objective was to explore IRs' beliefs about factors influencing CT utilization in mTBIs using TDF in Uganda.Differences in the factors influencing CTS ordering behavior across specialties, levels of experience, and hospital category were also explored. Materials and Methods: In-depth semi-structured interviews guided by TDF were conducted among purposively selected IRs from 6 tertiary public and private hospitals with functional CTS services. A thematic analysis was performed with codes and emerging themes developed based on the TDF. Results: Eleven IRs including medical officers, non-neurosurgeon specialists and neurosurgeons aged on average 42 years (SD+/-12.3 years) participated.Identified factors within skills domain involved IRs' clinical assessment and decision-making abilities, while beliefs about capabilities and consequences encompassed their confidence in diagnostic abilities and perceptions of CTS risks and benefits. The environmental context and resources domain addressed the availability of CT scanners and financial constraints. The knowledge domain elicited IRs' understanding of clinical guidelines and evidence-based practices while social influences considered peer influence and institutional culture. For memory, attention & decision processes domain, IRs adherence to guidelines and intentions to order CT scans were cited. Conclusion: Using TDF, IRs identified several factors believed to influence decision making to order CTS in mTBI in a LRS. The findings can inform stakeholders to develop targeted strategies and evidence-based interventions to optimize CT utilization in mTBI such as; educational programs, workflow modifications, decision support tools, and infrastructure improvements, among others.

Barriers and facilitators to implementing clinical imaging guidelines by healthcare professionals using theoretical domains framework: a mixed-methods systematic review protocol.

Objectives: To identify, categorize, and develop an aggregated synthesis of evidence using the theoretical domains framework (TDF) on barriers and facilitators that influence implementation of clinical imaging guidelines (CIGs) by healthcare professionals (HCPs) in diagnostic imaging. Methods: The protocol will be guided by the Joanna Briggs Institute Reviewers' Manual 2014. Methodology for JBI Mixed Methods Systematic Reviews and will adhere to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA-P). Information source will include databases (MEDLINE, EMBASE and The Cochrane Library), internet search (https://www.google.com/scholar), experts' opinion, professional societies/organizations websites and government bodies strategies/recommendations, and reference lists of included studies. Articles of any study design published in English from 1990 to date, having investigated factors operating as barriers and/or facilitators to the implementation CIGs by HCPs will be eligible. Selecting, appraising, and extracting data from the included studies will be independently performed by at least two reviewers using validated tools and Rayyan - Systematic Review web application. Disagreements will be resolved by consensus and a third reviewer as a tie breaker. The aggregated studies will be synthesized using thematic analysis guided by TDF. Results: Identified barriers will be defined a priori and mapped into 7 TDF domains including knowledge, awareness, effectiveness, time, litigationand financial incentives. Conclusion: The results will provide an insight into a theory-based approach to predict behavior-related determinants for implementing CIGs and develop strategies/interventions to target the elicited behaviors. Recommendations will be made if the level of evidence is sufficient. Advances in knowledge: Resource-constrained settings that are in the process of adopting CIGs may opt for this strategy to predict in advance likely impediments to achieving the goal of CIG implementation and develop tailored interventions during the planning phase.Systematic review Registration: PROSPERO ID = CRD42020136372 (https://www.crd.york.ac.uk/PROSPERO).

An audit of registered radiology equipment resources in Uganda.

INTRODUCTION: the third Sustainable Development Goal (SDG) relates to Universal Health Coverage (UHC) and provision of quality essential health services. The Government of Uganda has operationalized this through the National Health Policy which stresses the importance of availability of functioning medical equipment in health facilities. There have been efforts by the Ministry of Health and Atomic Energy Council in Uganda to compile an inventory of imaging equipment in the country, however, this information has not been widely published. The purpose of this study was to conduct an audit of registered radiology equipment in Uganda and establish their functional status. METHODS: a cross-sectional descriptive study that involved a desktop review of the equipment registry at the Uganda Atomic Energy Council was conducted. Data was collected on a number of variables including type of equipment, location, functional status, modality and density per million people. RESULTS: the audit revealed 625 pieces of equipment spread over 354 health facilities. The majority (397) were plain X-ray machines followed by dental X-ray machines at 120. There were only 3 Radiotherapy machines. Most were recorded as being functional with only 0.1% of the equipment non-functional. Most of the equipment was in the central region which has the third highest population density. The majority of the equipment belonged to private health facilities. CONCLUSION: Uganda lags behind the WHO recommended ratio of equipment versus the population (20 per million population). Most of the equipment is the plain X-ray machine with a few more advanced technologies in both public and private health facilities.

Ancillary benefits of antenatal ultrasound: an association between the introduction of a low-cost ultrasound program and an increase in the numbers of women receiving recommended antenatal treatments.

BACKGROUND: In June of 2010, an antenatal ultrasound program was introduced to perform basic screening examinations at a health care clinic in rural Uganda. The impact of the program on the existing antenatal care infrastructure including the proportion and number of women receiving recommended antenatal care at clinic visits was unknown. The aim of this study was to investigate the relationship between the advent of the ultrasound program and the proportion of women receiving recommended antenatal interventions at their clinic visits. Change in the absolute numbers of antenatal services provided was also assessed. METHODS: Records at the Nawanyago clinic were reviewed to determine the total numbers of women receiving specific interventions before and after the advent of the ultrasound program including HIV testing, intermittent preventive therapy for malaria, presumptive anti-parasitic treatment, and provision of iron and folate for anemia. The rate at which these interventions were provided (number of interventions per clinic visit) was also assessed. The differences in absolute numbers of antenatal interventions before and after the introduction of the ultrasound program were assessed using the Wilcoxon rank-sum test. Differences in intervention rate were assessed using negative binomial regression modeling. RESULTS: The mean monthly numbers of women receiving each of these interventions increased significantly with the greatest increase seen in numbers of women receiving anemia and deworming treatments at +113% and +102% respectively (p < 0.001). The intervention rate increased for anemia treatment, deworming treatment, and 2nd dose of intermittent preventive therapy for malaria. A slight decrease in intervention rate was observed for 1st dose of malaria treatment with a rate ratio of 0.88 (0.79 - 0.98, 95% CI). Intervention rate for HIV testing was not significantly changed. CONCLUSION: The introduction of a low-cost antenatal ultrasound program at a health care clinic in rural Uganda was associated with increases in the number of women receiving specific recommended antenatal care interventions. Effect on intervention rates was mixed but showed an overall increase. The use of ultrasound in this context may provide a benefit to the maternal and neonatal health of the community.

A low-cost ultrasound program leads to increased antenatal clinic visits and attended deliveries at a health care clinic in rural Uganda.

BACKGROUND: In June of 2010, an antenatal ultrasound program to perform basic screening for high-risk pregnancies was introduced at a community health care center in rural Uganda. Whether the addition of ultrasound scanning to antenatal visits at the health center would encourage or discourage potential patients was unknown. Our study sought to evaluate trends in the numbers of antenatal visits and deliveries at the clinic, pre- and post-introduction of antenatal ultrasound to determine what effect the presence of ultrasound at the clinic had on these metrics. METHODS AND FINDINGS: Records at Nawanyago clinic were reviewed to obtain the number of antenatal visits and deliveries for the 42 months preceding the introduction of ultrasound and the 23 months following. The monthly mean deliveries and antenatal visits by category (first visit through fourth return visit) were compared pre- and post- ultrasound using a Kruskal-Wallis one-way ANOVA. Following the introduction of ultrasound, significant increases were seen in the number of mean monthly deliveries and antenatal visits. The mean number of monthly deliveries at the clinic increased by 17.0 (13.3-20.6, 95% CI) from a pre-ultrasound average of 28.4 to a post-ultrasound monthly average of 45.4. The number of deliveries at a comparison clinic remained flat over this same time period. The monthly mean number of antenatal visits increased by 97.4 (83.3-111.5, 95% CI) from a baseline monthly average of 133.5 to a post-ultrasound monthly mean of 231.0, with increases seen in all categories of antenatal visits. CONCLUSIONS: The availability of a low-cost antenatal ultrasound program may assist progress towards Millennium Development Goal 5 by encouraging women in a rural environment to come to a health care facility for skilled antenatal care and delivery assistance instead of utilizing more traditional methods.

Evaluation of US training for the past 6 years at ECUREI, the World Federation for Ultrasound in Medicine and Biology (WFUMB) Centre of Excellence, Kampala, Uganda.

RATIONALE AND OBJECTIVES: The objectives of this article are: To explore the impact of the Radiological Society of North America-sponsored "Teach the Teachers" training course and other capacity building interventions (CBIs) on Uganda's ultrasound (US) training capacity; compare performance of students undertaking a modular diploma ultrasound course to the non-modular; and compare performance among various health cadres undertaking US training. MATERIALS AND METHODS: The impact of the "Teach the Teachers" training course and other capacity building interventions were evaluated through analysis of the planning, implementation, sustainability, and output of the training center. Comparison of students' performance in the modular and non-modular diploma courses was by a retrospective cohort methodology using odds ratios. Comparison of performance was by analyzing their mean test scores using a paired Student t-test. RESULTS: To date, 306 students from nine African countries have successfully completed the US diploma training. Fifty (16%) are non-Ugandans. The non-modular cohort has performed better than the modular (OR = 3.2) in the final written examination. The mean test scores for the final written examinations were: 73.4%, 71.9%, 61.2%, and 57% for the doctors, radiographers, assistant physicians, and nurses/midwives, respectively. CONCLUSION: The Radiological Society of North America-sponsored "Teach the Teacher's course in US" together with other capacity building interventions have led to an established center of excellence for US training in Uganda.
