Inhospital Mortality in Patients with Type 2 Diabetes Mellitus: A Prospective Cohort Study in Lima, Peru

Table 1

Definition of causes of hospitalization assessed in the study.

Infections
RespiratoryRespiratory symptoms (cough or tachypnea) plus a chest X-ray with changes suggestive of viral or bacterial respiratory infection.
UrinaryUrine sample with ≥10 leukocytes/µL [30], temperature > 38.0°C, and not being able to orally tolerate fluids/food.
GastrointestinalDiarrhea < 7 days, vomiting, and dehydration.
Subcutaneous tissue (SCT)Cellulitis or necrotizing fasciitis in any part of the body except feet.
Diabetic footUlceration, infection, and/or gangrene of foot associated with diabetic neuropathy and different grades of peripheral artery disease [21].

Metabolic disorders
HypoglycemiaGlucose ≤70 mg/dL (3.9 mmol/L) [21].
Diabetic ketoacidosisGlucose >250 mg/dL, pH <7.3, and bicarbonate <18 mEq/d [21].
Hyperosmolar stateGlucose >600 mg/dL, pH arterial: >7.30, bicarbonate: >18 mEq/L, anion GAP: variable, mental status: drowsy/coma, few kenotic bodies in the urine and blood, and plasmatic osmolality > 320 mOsm/kg [21].

Vascular
StrokeFast development of clinic signs of changes in the cerebral function or global, with symptoms that persist within 24 hours or more, with no other evidence of vascular origin [21].

Renal
Acute renal failureSudden increase (within 48 hours) of creatinine (Cr)
≥0.3 mg/dL (26.4 micromol/L) of basal or a percentage of increment of Cr of ≥50%; or oliguria of <0.5 mL/kg/hour by more than six hours [31].
Chronic renal failure Presence of renal damage (urinary albumin excretion ≥30 mg/day) or decrease of the renal function (GFR <60 mL/min/1.73 m2) by three or more months, independent of the cause [32] documented as past medical history plus acute renal failure at the moment of admission (exacerbation).
