Underutilization of Operative Capacity at the District Hospital Level in a Resource-Limited Setting

Acute care surgery in a Malawian district hospital: Epidemiology, outcomes, and assessment of operative capacity

District hospitals (DHs) care for the majority of surgical patients in Malawi, but data on district hospital surgical capacity are limited. We sought to evaluate the management and outcomes of surgical patients presenting to Salima District Hospital (SDH) in Malawi. Using the SDH surgery registry, we compared patients managed operatively and those non-operatively and performed logistic regression to identify factors associated with operative management. We then compared cases performed at SDH with procedures recommended to be performed at DHs. We included 1374 patients, of whom half were managed operatively. The most common procedures performed were abscess drainage and wound debridement. Logistic regression analysis revealed that patients with abdominal diagnoses were least likely to be treated operatively. Though SDH performs most procedures recommended for the district hospital level, patients requiring laparotomies were most likely to be transferred to a referral hospital. Future studies should assess barriers to performing laparotomies at SDH.

Malawi Trauma Score is Predictive of Mortality at a District Hospital: A Validation Study

BACKGROUND

Trauma scoring systems can identify patients who should be transferred to referral hospitals, but their utility in LMICs is often limited. The Malawi Trauma Score (MTS) reliably predicts mortality at referral hospitals but has not been studied at district hospitals. We sought to validate the MTS at a Malawi district hospital and evaluate whether MTS is predictive of transfer to a referral hospital.

METHODS

We performed a retrospective study using trauma registry data from Salima District Hospital (SDH) from 2017 to 2021. We excluded patients brought in dead, discharged from the Casualty Department, or missing data needed to calculate MTS. We used logistic regression modeling to study the relationship between MTS and mortality at SDH and between MTS and transfer to a referral hospital. We used receiver operating characteristic analysis to validate the MTS as a predictor of mortality.

RESULTS

We included 2196 patients (84.3% discharged, 12.7% transferred, 3.0% died). These groups had similar ages, sex, and admission vitals. Mean (SD) MTS was 7.9(3.0) among discharged patients, 8.4(3.9) among transferred patients, and 14.2(8.0) among patients who died (p < 0.001). Higher MTS was associated with increased odds of mortality at SDH (OR 1.21, 95% CI 1.14-1.29, p < 0.001) but was not related to transfer. ROC area for mortality was 0.73 (95% CI 0.65-0.80).

CONCLUSIONS

MTS is predictive of district hospital mortality but not inter-facility transfer. We suggest that MTS be used to identify patients with severe trauma who are most likely to benefit from transfer to a referral hospital.

The impact of resource limitations on care delivery and outcomes: routine variation, the coronavirus disease 2019 pandemic, and persistent shortage

PURPOSE OF REVIEW

Resource limitation, or capacity strain, has been associated with changes in care delivery, and in some cases, poorer outcomes among critically ill patients. This may result from normal variation in strain on available resources, chronic strain in persistently under-resourced settings, and less commonly because of acute surges in demand, as seen during the coronavirus disease 2019 (COVID-19) pandemic.

RECENT FINDINGS

Recent studies confirmed existing evidence that high ICU strain is associated with ICU triage decisions, and that ICU strain may be associated with ICU patient mortality. Studies also demonstrated earlier discharge of ICU patients during high strain, suggesting that strain may promote patient flow efficiency. Several studies of strain resulting from the COVID-19 pandemic provided support for the concept of adaptability - that the surge not only caused detrimental strain but also provided experience with a novel disease entity such that outcomes improved over time. Chronically resource-limited settings faced even more challenging circumstances because of acute-on-chronic strain during the pandemic.

SUMMARY

The interaction between resource limitation and care delivery and outcomes is complex and incompletely understood. The COVID-19 pandemic provides a learning opportunity for strain response during both pandemic and nonpandemic times.

Are Surgeons Enough? The Relationship between Increasing Surgical Demand and Access to Surgery in a Resource-Limited Environment

INTRODUCTION

The relationship between increasing surgical demand and access to operative intervention remains unclear in delivering general surgical care in resource-limited settings, where demand often exceeds capacity. We sought to characterize the association between general surgery patient volume and operative intervention at a tertiary hospital in Malawi, which has an adequate surgical workforce.

METHODS

We analyzed patients admitted to Kamuzu Central Hospital Lilongwe, Malawi, with a general surgery complaint from 2018-2020. We examined the relationship between the census at the time of admission, the use of operative intervention, and the time to operative intervention. The patient census was defined as low (≤30 patients), medium (31-49 patients), and high (≥50 patients), based on historical patterns.

RESULTS

2,701 patients were included. The mean daily census was 46 patients (SD 10). For the medium and high census, the adjusted risk ratio of undergoing surgery was 0.86 (95% CI 0.78, 0.95) and 0.81 (95% CI 0.73, 0.90), respectively, adjusted for admission diagnosis. For patients requiring urgent abdominal exploration, at a census of 25, the adjusted mean time to operation was 0.8 days (95% CI 0.1, 1.5) compared to 2.8 days (95% CI 2.1, 3.5) at a census of 65 patients.

CONCLUSIONS

Despite an adequate surgical workforce, an increasing mean daily census significantly reduced the use of operative intervention and increased time to operation for patients who needed urgent abdominal exploration. Additional improvements in the surgical ecosystem beyond surgeons are necessary to improve surgical access.
