Standardized trauma intake form with clinical decision support prompts improves care and reduces mortality for seriously injured patients in non-tertiary hospitals in Ghana: stepped-wedge cluster randomized trial

Synthesizing the Evidence Base to Enhance Coordination between Humanitarian Mine Action and Emergency Care for Casualties of Explosive Ordnance and Explosive Weapons: A Scoping Review

BACKGROUND

Humanitarian mine action (HMA) stakeholders have an organized presence with well-resourced medical capability in many conflict and post-conflict settings. Humanitarian mine action has the potential to positively augment local trauma care capacity for civilian casualties of explosive ordnance (EO) and explosive weapons (EWs). Yet at present, few strategies exist for coordinated engagement between HMA and the health sector to support emergency care system strengthening to improve outcomes among EO/EW casualties.

METHODS

A scoping literature review was conducted to identify records that described trauma care interventions pertinent to civilian casualties of EO/EW in resource-constrained settings using structured searches of indexed databases and grey literature. A 2017 World Health Organization (WHO) review on trauma systems components in low- and middle-income countries (LMICs) was updated with additional eligible reports describing trauma care interventions in LMICs or among civilian casualties of EO/EWs after 2001.

RESULTS

A total of 14,195 non-duplicative records were retrieved, of which 48 reports met eligibility criteria. Seventy-four reports from the 2017 WHO review and 16 reports identified from reference lists yielded 138 reports describing interventions in 47 countries. Intervention efficacy was assessed using heterogenous measures ranging from trainee satisfaction to patient outcomes; only 39 reported mortality differences. Interventions that could feasibly be supported by HMA stakeholders were synthesized into a bundle of opportunities for HMA engagement designated links in a Civilian Casualty Care Chain (C-CCC).

CONCLUSIONS

This review identified trauma care interventions with the potential to reduce mortality and disability among civilian EO/EW casualties that could be feasibly supported by HMA stakeholders. In partnership with local and multi-lateral health authorities, HMA can leverage their medical capabilities and expertise to strengthen emergency care capacity to improve trauma outcomes in settings affected by EO/EWs.

An evaluation of the Hawthorne effect in a clinical trial of trauma care in Ghana

INTRODUCTION

Hawthorne effect refers to changes in clinician behavior in response to being observed. It has been minimally evaluated in trauma and surgical research, especially in low- and middle-income countries (LMICs).

METHODS

We used data from the first (control) phase of a randomized clinical trial in Ghana (2020-21). Trained observers were stationed in emergency units in eight non-tertiary hospitals to observe the achievement of key performance indicators (KPI) (KPIs) of trauma care. We hypothesized that the observers' presence would create a Hawthorne effect, resulting in clinicians (doctors, nurses) performing above their usual level, with performance highest immediately after the observers were introduced, and with performance then declining over time toward the usual baseline.

RESULTS

We enrolled 2067 injured patients. Achievement of 13 out of 16 KPIs declined significantly over the 14 months after the introduction of observers. For example, airway assessment declined from 77% initially to 60% at the end of the phase (p < 0.001). Chest examination declined from 66% to 31% (p < 0.001). Distal pulses checked declined from 45% to 7% (p < 0.001). The slope of decline in KPI achievement ranged from 0.8%/month (mobility assessed) to 15.9%/month (distal pulses checked).

CONCLUSIONS

The decline in KPI achievement over time is consistent with the hypothesis that clinicians performed above their usual level just after the observers were introduced, with performance then declining toward the usual baseline. This study is among the first to provide quantitative data on the Hawthorne effect for trauma research in LMICs. These data are useful for the design of future observational studies and clinical trials.

Improvement in quality of trauma care at non-tertiary hospitals in Ghana during on-hours and off-hours with a trauma intake form: A stepped-wedge cluster randomized trial

BACKGROUND

We sought to determine the achievement of key performance indicators (KPIs) of initial trauma care at non-tertiary hospitals in Ghana during on-hours (8AM-5PM weekdays) compared to off-hours (nights, weekends, and holidays). We also sought to assess the effectiveness of a standardized trauma intake form (TIF) with built-in decision support prompts to improve care and to assess whether this effectiveness varied between on-hours and off-hours.

METHODS

A stepped-wedge cluster randomized trial was performed with research assistants directly observing trauma care before and after introducing the TIF at emergency units of eight hospitals for 17.5 months. Differences in KPIs and mortality were assessed using multivariable logistic regression and generalized linear mixed regression.

RESULTS

Management of 4,077 patients was observed; 1,126 (28 %) during on-hours and 2,951(72 %) during off-hours. At baseline, four of 20 KPIs were performed significantly more often during off-hours. TIF improved care during both on- and off-hours. Seventeen KPIs improved during on-hours and 18 KPIs improved during off-hours. After TIF, six KPIs were performed more often during on-hours, but differences, though significant, were small (1-5 %). Examples of KPIs which were performed more often during on-hours after TIF included: airway assessment (99 % for on-hours vs. 98 % for off-hours), evaluation for intra-abdominal bleeding (91 % vs. 87 %), and spine immobilization for blunt trauma (90 % vs. 85 %) (all p < 0.05). At baseline, mortality among seriously injured patients (Injury Severity Score >9) was higher during on-hours (27 %) compared to off-hours (17 %, p = 0.047). TIF lowered mortality for seriously injured patients during both on-hours (27 % before TIF, 8 % after, p = 0.027) and during off-hours (17 % before, 7 % after, p = 0.004). After TIF, mortality among seriously injured patients was equal between on- and off-hours (8 % vs. 7 %, NS).

CONCLUSIONS

At baseline, KPIs of trauma care were slightly better during off-hours compared with on-hours, and mortality was lower among seriously injured patient during off-hours. A quality improvement initiative (the TIF) using built-in decision support prompts improved care strongly in both on- and off-hours and eliminated the mortality difference between on- and off-hours. Use of similar decision support prompts during initial trauma care should be promoted widely in other low- and middle-income countries.

Experiences of injured patients referred to higher levels of care after initial assessment and management at non-tertiary hospitals in Ghana

Background

The experiences of trauma patients referred from Ghanaian non-tertiary hospitals for definitive care at higher levels is not well-known. Understanding the motivations of injured patients who do not attend their referral for definitive management may inform interventions to improve injury outcomes.

Methods

This study is a follow-up survey of participants of a larger study involving initial management of injured patients presenting to 8 non-tertiary hospitals in Ghana from October 2020 to March 2022. Injured patients referred to higher levels of care were surveyed by phone using a structured questionnaire and patients who could not be reached were excluded. The main outcome was referral non-attendance and differences between patients who attended the referral and those who did not were determined with chi squared tests. Variables with intergroup differences were included in a multivariable logistic regression. Open-ended survey responses were analyzed using thematic content analysis.

Results

Of 335 referred patients surveyed, 17 % did not attend the referral. Factors associated with referral non-attendance included being male (Adjusted odds ratio (AOR)=2.70, p = 0.013), sustaining a fracture (AOR=2.83, p = 0.003), and having less severe injury (AOR 2.84, p = 0.017). Primary drivers of referral non-attendance included financial problems (59 %), family influence (45 %), and lack of transportation (20 %). The majority of patients (77 %) not attending the referral sought treatment from traditional healers, citing lower cost, faster service, and a perception of equivalent outcomes. Reported facilitators of referral attendance included positive hospital staff experiences and treatment while barriers included higher hospital costs, lack of bed space, and poor interhospital communication.

Conclusions

An important proportion of injured patients in Ghana do not attend referrals for definitive management, with many seeking care from traditional healers. Our study identified possible targets for interventions aimed at maintaining the continuum of hospital-based care for injured patients in order to improve outcomes.

Assessment and reassessment of injured patients at non-tertiary hospitals in Ghana: A stepped-wedge cluster randomized trial

Introduction

Frequent reassessment of injured patients is an important component of trauma and emergency care. How frequently such reassessment is done in African hospitals has been minimally addressed. We sought to address this gap, as well as to assess the effectiveness of a standardized trauma intake form (TIF) to improve assessment and reassessment rates.

Methods

We undertook a stepped-wedge cluster randomized trial with research assistants observing trauma care before and after introducing the TIF at emergency units of eight non-tertiary Ghanaian hospitals for 17.5 months. Differences in seven key performance indicators (KPIs) of assessment and reassessment were evaluated using generalized linear mixed regression. KPIs included: respiratory rate, heart rate, blood pressure, level of consciousness, mobility, temperature, and oxygen saturation.

Results

Management of 4077 patients was observed: 2067 before TIF initiation and 2010 after. In the before period, completion of KPIs of initial assessment ranged from 55% (oxygen saturation) to 88% (level of consciousness). KPIs for reassessment for patients still in the EU after 30 min (n = 1945, in before period) were much lower than for initial assessment, ranging from 10% (respiratory rate and oxygen saturation) to 13% (level of consciousness). The TIF did not significantly improve performance of any KPI of assessment or reassessment. Similar patterns pertained for the subgroup of seriously injured patients (Injury Severity Score ≥9).

Conclusion

At non-tertiary hospitals in Ghana, performance of KPIs of initial assessment were mostly adequate, but with room for improvement. Performance of KPIs for reassessment were very low, even for seriously injured patients. The intervention (trauma intake form) did not impact reassessment rates, despite previously having been shown to impact many other KPIs of trauma care. Potential avenues to pursue to improve reassessment rates include other quality improvement efforts and increased emphasis on reassessment in training courses.

Care of Injured Children Compared to Adults at District and Regional Hospitals in Ghana and the Impact of a Trauma Intake Form: A Stepped-Wedge Cluster Randomized Trial

BACKGROUND

This study aimed to determine the effectiveness of a standardized trauma intake form (TIF) to improve achievement of key performance indicators (KPIs) of initial trauma care among injured children, compared to adults, at non-tertiary hospitals in Ghana.

METHODS

A stepped-wedge cluster randomized trial was performed with research assistants directly observing the management of injured patients before and after introducing the TIF at emergency units of 8 non-tertiary hospitals for 17.5 months. Differences in outcomes between children and adults in periods before and after TIF introduction were determined with multivariable logistic regression. Differences in outcomes among children after TIF introduction were determined using generalized linear mixed regression.

RESULTS

Management of 3889 injured patients was observed; 757 (19%) were children <18 years. Trauma care KPIs at baseline were lower for children compared to adults. Improvements in primary survey KPIs were observed among children after TIF introduction. Examples include airway assessment [279 (71%) to 359 (98%); adjusted odds ratio (AOR): 74.42, p = 0.005)] and chest examination [225 (58%) to 349 (95%); AOR 53.80, p = 0.002)]. However, despite these improvements, achievement of KPIs was still lower compared to adults. Examples are pelvic fracture evaluation [children: 295 (80%) vs adults: 1416 (88%), AOR: 0.56, p = 0.001] and respiratory rate assessment (children: 310 (84%) vs adults: 1458 (91%), AOR: 058, p = 0.030).

CONCLUSIONS

While the TIF was effective in improving most KPIs of pediatric trauma care, more targeted education is needed to bridge the gap in quality between pediatric and adult trauma care at non-tertiary hospitals in Ghana and other low- and middle-income countries.

Differences in trauma care between district and regional hospitals and impact of a trauma intake form with decision support prompts in Ghana: A stepped-wedge cluster randomized trial

BACKGROUND

We sought to determine the achievement of key performance indicators (KPIs) of initial trauma care at district (first-level) and regional (second-level) hospitals in Ghana and to assess the effectiveness of a standardized trauma intake form (TIF) to improve care.

METHODS

A stepped-wedge cluster randomized trial was performed with direct observations of trauma management before and after introducing the TIF at emergency units of eight hospitals for 17.5 months. Differences in KPIs were assessed using multivariable logistic regression and generalized linear mixed regression.

RESULTS

Management of 4077 patients was observed; 30% at regional and 70% at district hospitals. Eight of 20 KPIs were performed significantly more often at regional hospitals. TIF improved care at both levels. Fourteen KPIs improved significantly at district and eight KPIs improved significantly at regional hospitals. After TIF, regional hospitals still performed better with 18 KPIs being performed significantly more often than district hospitals. After TIF, all KPIs were performed in >90% of patients at regional hospitals. Examples of KPIs for which regional performed better than district hospitals after TIF included: assessment for oxygen saturation (83% vs. 98%) and evaluation for intra-abdominal bleeding (82% vs. 99%, all p < 0.001). Mortality decreased among seriously injured patients (injury severity score ≥9) at both district (15% before vs. 8% after, p = 0.04) and regional (23% vs. 7%, p = 0.004) hospitals.

CONCLUSIONS

TIF improved care and lowered mortality at both hospital levels, but KPIs remained lower at district hospitals. Further measures are needed to improve initial trauma care at this level.
