Characteristics and outcomes of pediatric patients presenting at Cambodian referral hospitals without appointments: an observational study.

BACKGROUND: Emergency medicine is a young specialty in many low- and middle-income countries (LMICs). Although many patients seeking emergency or acute care are children, little information is available about the needs and current treatment of this group in LMICs. In this observational study, we sought to describe characteristics, chief complaints, management, and outcomes of children presenting for unscheduled visits to two Cambodian public hospitals. METHODS: Children enrolled in the study presented without appointment for treatment at one of two Cambodian public referral hospitals during a 4-week period in 2012. Researchers used standardized questionnaires and hospital records to collect demographic and clinical data. Patients were followed up at 48 h and 14 days after initial presentation. Multivariate logistic regression identified factors associated with hospital admission. RESULTS: This study included 867 unscheduled visits. Mean patient age was 5.7 years (standard deviation 4.8 years). Of the 35 different presenting complaints, fever (63%), respiratory problems (25%), and skin complaints (24%) were most common. The majority of patients were admitted (51%), while 1% were transferred to another facility. Seven patients (1%) died within 14 days. Follow-up rates were 83% at 48 h and 75% at 14 days. Predictors of admission included transfer or referral from another health provider, seeking prior care for the presenting problem, low socioeconomic status, onset of symptoms within 24 h of seeking care, abnormal vital signs or temperature, and chief complaint of abdominal pain or fever. CONCLUSIONS: While the admission rate in this study was high, mortality was low. More effective identification and management of children who can be treated and released may free up scarce inpatient resources for children who warrant admission.

An observational study of adults seeking emergency care in Cambodia.

OBJECTIVE: To describe the characteristics and chief complaints of adults seeking emergency care at two Cambodian provincial referral hospitals. METHODS: Adults aged 18 years or older who presented without an appointment at two public referral hospitals were enrolled in an observational study. Clinical and demographic data were collected and factors associated with hospital admission were identified. Patients were followed up 48 hours and 14 days after presentation. FINDINGS: In total, 1295 hospital presentations were documented. We were able to follow up 85% (1098) of patients at 48 hours and 77% (993) at 14 days. The patients' mean age was 42 years and 64% (823) were females. Most arrived by motorbike (722) or taxi or tuk-tuk (312). Most common chief complaints were abdominal pain (36%; 468), respiratory problems (15%; 196) and headache (13%; 174). Of the 1050 patients with recorded vital signs, 280 had abnormal values, excluding temperature, on arrival. Performed diagnostic tests were recorded for 539 patients: 1.2% (15) of patients had electrocardiography and 14% (175) had diagnostic imaging. Subsequently, 783 (60%) patients were admitted and 166 of these underwent surgery. Significant predictors of admission included symptom onset within 3 days before presentation, abnormal vital signs and fever. By 14-day follow-up, 3.9% (39/993) of patients had died and 19% (192/993) remained functionally impaired. CONCLUSION: In emergency admissions in two public hospitals in Cambodia, there is high admission-to-death ratio and limited application of diagnostic techniques. We identified ways to improve procedures, including better documentation of vital signs and increased use of diagnostic techniques.

An innovative approach to in-service training of maternal health staff in Cambodian hospitals.

OBJECTIVE: To demonstrate the feasibility of implementing evidence-based continuing medical education (CME) to improve key skills among maternity staff in Cambodia. METHODS: A skills-based CME program was implemented in 33 Cambodian hospitals. Each clinical skills practice (CSP) module consisted of a 1-day practice session, focusing on three maternal and newborn interventions, followed by support visits to participating hospitals. Skills were assessed at 27 intervention hospitals and five control hospitals 7-11 months after the practice sessions through observation of neonatal resuscitation, magnesium sulfate dilution, and aortic compression simulations. RESULTS: A total of 559 healthcare workers attended at least one CSP practice session. The skills assessment included 47 doctors and 210 midwives. Hospital staff who participated in CSP performed significantly better than did those from control hospitals on neonatal resuscitation (mean score 31.22 vs 17.00; P<0.001), magnesium sulfate dilution (mean score 11.01 vs 8.47; P<0.001), and aortic compression (mean score 13.87 vs 4.33; P<0.001). CSP participants were also significantly more likely to score higher than the 70% cutoff for neonatal resuscitation and magnesium sulfate dilution than were those from control hospitals, after adjustment for hospital level and profession (P≤0.05). CONCLUSION: Key clinical skills in low-resource settings can be improved by implementing CME using simulations and supportive follow-up.

Rapid scaling-up of antiretroviral therapy in 10,000 adults in Côte d'Ivoire: 2-year outcomes and determinants.

OBJECTIVE: To assess the rates and determinants of mortality, loss to follow-up and immunological failure in a nongovernmental organization-implemented program of access to antiretroviral treatment in Côte d'Ivoire. METHODS: In each new treatment center, professionals were trained in HIV care, and a computerized data system was implemented. Individual patient and program level determinants of survival, loss to follow-up and immunological failure were assessed by multivariate analysis. RESULTS: Between May 2004 and February 2007, 10,211 patients started antiretroviral treatment in 19 clinics (median preantiretroviral treatment CD4 cell count, 123 cells/microl; initial regimen zidovudine-lamivudine-efavirenz, 20%; stavudine-lamivudine-efavirenz, 22%; stavudine-lamivudine-nevirapine, 52%). At 18 months on antiretroviral treatment, the median gain in CD4 cell count was +202 cells/microl, the probability of death was 0.15 and the probability of being loss to follow-up was 0.21. In addition to the commonly reported determinants of impaired outcomes (low CD4 cell count, low BMI, low hemoglobin, advanced clinical stage, old age and poor adherence), two factors were also shown to independently jeopardize prognosis: male sex (men vs. women: hazard ratio = 1.52 for death, 1.27 for loss to follow-up, 1.31 for immunological failure); and attending a recently opened clinic (inexperienced vs. experienced centers: hazard ratio = 1.40 for death, 1.58 for loss to follow-up). None of the three outcomes was associated with the drug regimen. DISCUSSION: In this rapidly scaling-up program, survival and immune reconstitution were good; women and patients followed up in centers with longer experience had better outcomes; outcomes were similar in zidovudine/stavudine-based regimens and in efavirenz/nevirapine-based regimens. Decreasing the rate of loss to follow-up should now be the top priority in antiretroviral treatment rollout.
