Insights
This systematic review highlights successful acute care interventions for ischemic heart disease (IHD), stroke, and lower respiratory infections (LRIs) in lower-middle-income countries (LMIC). Further research is needed, particularly from Central and South America.
Area of Science:
- Global Health
- Critical Care Medicine
- Epidemiology
Background:
- Ischemic heart disease (IHD), stroke, and lower respiratory infections (LRIs) are leading causes of mortality in lower-middle-income countries (LMIC).
- Patients in LMIC often face healthcare barriers, leading to critical disease presentation.
- Published critical care implementations in LMIC lack formal review.
Purpose of the Study:
- To systematically review published literature on acute care interventions for IHD, stroke, and LRIs in LMIC.
- To identify successful diagnostic and treatment measures implemented in LMIC.
- To highlight research gaps, particularly in Central and South America.
Main Methods:
- Systematic literature review of PubMed indexed studies up to October 2017.
- Inclusion criteria: human studies in English, French, or Spanish, conducted in LMIC, with quantitative data on acute care for IHD, stroke, and LRI.
- Initial search yielded 4994 abstracts; 161 manuscripts were selected after screening.
Main Results:
- The review identified 161 relevant manuscripts, predominantly from Asia.
- Successful diagnostic and treatment measures were demonstrated for IHD, stroke, and LRI in LMIC settings.
- Significant lack of original research from Central and South America was noted.
Conclusions:
- Acute care interventions for IHD, stroke, and LRIs have been successfully studied and published in LMIC.
- Specific interventions include monitoring, medications, thrombolytics, percutaneous intervention, coronary artery bypass graft for IHD; therapeutic hypothermia, medications, thrombolytics for stroke; and oxygen saturation measurement, diagnostic ultrasound, oxygen, antibiotics for LRI.
- There is a critical need for more research originating from Central and South America to address these major causes of mortality in LMIC.
Abstract:
According to the World Health Organization, the three leading causes of mortality in lower-middle-income countries (LMIC) are ischemic heart disease (IHD), stroke, and lower respiratory infections (LRIs), causing 111.8, 68.8, and 51.5 annual deaths per 100,000, respectively. Due to barriers to healthcare, patients frequently present in critical stages of these diseases. Measured implementations in critical care in LMIC have been published; however, the literature has not been formally reviewed. We performed a systematic review of the literature indexed in PubMed as of October 2017. Abstracts were limited to human studies in English, French, and Spanish, conducted in LMIC, and containing quantitative data on acute care of IHD, stroke, and LRI. The search resulted in 4994 unique abstracts. Through multiple rounds of screening using criteria determined a priori, 161 manuscripts were identified: 38 for IHD, 20 for stroke, 26 for adult LRI, and 78 for pediatric LRI. These studies, predominantly from Asia, demonstrate successful diagnostic and treatment measures used in providing acute care for patients in LMIC. Given that, only four manuscripts originated in Central or South America, original research from these areas is lacking. IHD, stroke, and LRIs are significant causes of mortality, especially in LMIC. Diagnostic and therapeutic interventions for IHD (monitoring, medications, thrombolytics, percutaneous intervention, coronary artery bypass graft), stroke (therapeutic hypothermia, medications, and thrombolytics), and LRI (oxygen saturation measurement, diagnostic ultrasound, administration of oxygen, appropriate antibiotics, and other medications) have been studied in LMIC and published.
