Protocolo de Manejo de la Diabetes Mellitus a Nivel Hospitalario

Objectives

Provide evidence-informed, standardised diabetes mellitus care across primary, secondary, ambulatory and hospital settings, within Nicaragua’s Ministry of Health Health Sector Modernisation Programme, to improve quality of care, reduce diabetes-related morbidity and mortality, and support quality of life.[1][2][3]The protocol covers prevention, early detection, diagnosis, treatment, follow-up and management of acute and chronic complications, including diabetes types 1 and 2 and gestational diabetes.[4][5][6]

• Promote early, risk-based identification of diabetes, particularly among people at increased risk, to reduce delayed diagnosis and chronic complications.[7]
• Achieve near-normal glycaemia where feasible, relieve symptoms, prevent hypoglycaemia, and reduce long-term microvascular and macrovascular complications through individualised treatment.[8]
• Control blood pressure, dyslipidaemia, procoagulant risk and other modifiable factors alongside glycaemic management.[9]
• Strengthen patient education, self-management, nutritional care, physical activity and healthy-weight maintenance to prevent acute and chronic complications.[2][10][9]
• Prevent, identify and manage ophthalmological, cardiovascular, cerebrovascular, peripheral vascular, renal, neurological and diabetic-foot complications.[11][12][13][14][15]
• Improve hospital care for severe metabolic decompensation, acute complications, pregnancy-related needs and perioperative diabetes management.[16][17][18]

Implementation

Deliver integrated, staged and individualised care through ambulatory and hospital protocols, combining clinical assessment, laboratory testing, lifestyle support, medicines, education, specialist referral and follow-up.[19][9][20]The Ministry of Health developed the guidance through consensus and contributions from professional societies, health workers, programme staff and personnel from pilot hospitals and health centres; the Ministry is identified as the competent authority for application, supervision and evaluation of health standards and programmes.[2][21][16]

• Apply a risk-stratified diagnostic pathway for asymptomatic adults, pregnant people, children and adolescents with risk factors, and symptomatic people.[21]Screen adults from age 45 or earlier where risk factors are present, and use fasting plasma glucose with repeat testing for diagnostic confirmation unless acute metabolic decompensation is present.[7]
• Assess gestational-diabetes risk at the first antenatal visit, test high-risk pregnant women promptly, reassess eligible women at 24 to 28 weeks, and reclassify affected women at least six weeks after delivery.[6]Manage diabetes in pregnancy through nutrition, glucose monitoring and insulin where dietary measures are insufficient, while adapting treatment to changing insulin requirements.[22][23]
• Conduct an initial diabetes assessment covering clinical and treatment history, diet, physical activity, medicines, psychosocial factors, self-management knowledge, cardiovascular risk and symptoms of complications.[9][24]Perform physical examination, laboratory investigations and cardiovascular, neurological, eye, renal and foot assessments.[24][11]
• Schedule subsequent ambulatory consultations according to clinical condition, initially at one- to four-week intervals where needed and with comprehensive reassessment at intervals of no more than three months.[9][11]Review glycaemic results, treatment adherence, self-monitoring, nutrition, self-care skills, new symptoms and future complication risk.[11][12]
• Use nutrition education, aerobic physical activity where appropriate, smoking cessation and weight management as core components of care, alongside glucose-lowering treatment.[2][23][25]
• Individualise pharmacological treatment according to diabetes type, clinical status, endogenous insulin deficiency, comorbidities and treatment response.[8][26]Combine diet and exercise with oral glucose-lowering medicines for type 2 diabetes where appropriate, use metformin or sulfonylureas within the stated clinical indications, and introduce insulin for severe hyperglycaemia, failure or intolerance of oral medicines, pregnancy, perioperative care and acute states.[26][27]
• Use insulin regimens with basal and prandial components, adjusting doses against fasting and post-prandial blood glucose and recognising increased hypoglycaemia risk with more intensive schedules.[28][29]Hospital care generally favours two daily doses of intermediate-acting neutral protamine Hagedorn insulin for stable patients, with three- or four-dose approaches for severe decompensation.[30]
• Refer patients as appropriate to ophthalmology, cardiology, nutrition, family planning, psychology, podiatry, dentistry, diabetes clubs and other specialist services.[11]Use emergency assessment, hospital admission, specialist referral or transfer according to severity and available hospital capacity for serious metabolic events and complications.[31]
• Screen and manage complications through periodic eye examination, vascular-risk assessment, renal testing, neuropathy evaluation and diabetic-foot examination.[12][13][14][32][33]Provide foot education on daily inspection, safe footwear, avoiding trauma and seeking prompt care for wounds.[15][34]
• Manage hospital admissions through comprehensive assessment, nutritional planning, daily follow-up, patient and family education, and transition to outpatient or primary-care follow-up.[20][35][36][37]Address diabetic ketoacidosis, hyperosmolar states, severe hypoglycaemia and severe hypertriglyceridaemia with intensive fluid, insulin, electrolyte and glucose monitoring as clinically indicated.[38][39][40][41]
• Apply perioperative protocols to optimise metabolic control before surgery, monitor plasma glucose frequently, maintain fluids and electrolytes, minimise hypoglycaemia and ketoacidosis, and restore oral feeding promptly.[18][42][43]

The protocol provides extensive clinical thresholds, testing intervals and treatment targets, but the supplied material does not specify programme-level performance indicators, routine reporting systems, audit arrangements, implementation budgets or financing mechanisms.[10][34][17]

Monitoring & Evaluation

The protocol establishes a clinically oriented monitoring framework for diabetes prevention, diagnosis, outpatient follow-up, complication assessment and hospital care. It specifies repeated diagnostic testing, regular clinical review, laboratory monitoring and treatment thresholds, while assigning the Ministry of Health responsibility for supervision, control and evaluation of compliance with health law, regulations, technical standards and programmes.[21]Formal programme-level indicators, reporting systems, surveillance arrangements, audit processes and implementation-accountability mechanisms are otherwise not specified in the supplied extracts.[19][17]

• Confirm diabetes diagnoses through repeat fasting plasma glucose testing on a separate day, except in acute metabolic decompensation; use an oral glucose tolerance test where fasting results are below the diagnostic threshold but clinical suspicion remains high.[7][10]
• Monitor gestational diabetes risk at the first prenatal consultation, reassess high-risk women at 24 to 28 weeks when initial fasting glucose is below 95 milligrams per decilitre, and reclassify women at least six weeks after delivery.[6]
• Screen children with overweight and additional risk factors from age 10 years, or earlier at puberty where applicable, and repeat normal fasting-glucose testing every two years.[44]
• Undertake initial diabetes assessment through medical history, physical examination, laboratory investigations, appraisal of diabetes knowledge and readiness to learn, and self-management education.[9]
• Review patients in outpatient care at intervals of one to four weeks according to clinical condition, with more comprehensive follow-up assessments at intervals of no more than three months, individualised to need.[9][11]
• Assess adherence, acute illness, hypoglycaemia symptoms, new complications and future complication risk at subsequent visits; review casual glucose, glycated haemoglobin, lipid profile and self-monitoring results.[11][12]
• Monitor diabetic eye disease through visual-acuity and dilated-fundus examination, undertaken by trained personnel or through early ophthalmology referral, with repeat examination annually or according to findings.[12][13]
• Screen renal complications annually through urine analysis and quantitative albumin assessment, particularly using the albumin-to-creatinine ratio; test people with type 1 diabetes after more than five years of disease and people with type 2 diabetes from diagnosis.[14]
• Confirm positive renal-screening results in the microalbuminuria range with two positive samples, and interpret albuminuria alongside clinical factors that may invalidate testing, including urinary infection, metabolic decompensation, fever, heart failure and menstruation.[14]
• Assess neuropathy and diabetic-foot risk through sensory thresholds, reflexes, muscle strength, vascular status, skin and nail changes, deformity, calluses, ulcers and possible Charcot arthropathy.[32][33]
• Schedule routine foot inspection, peripheral-pulse assessment, foot-sensitivity testing, blood-glucose and urine testing at initial, three-monthly and annual review intervals specified in the follow-up annex.[34]
• Use clinical control measures including fasting, pre-meal, bedtime and post-prandial glucose, glycated haemoglobin, lipid profile, body mass index, waist measures and blood pressure.[45][8]Basal insulin response is assessed through fasting glucose and prandial response through post-prandial glucose measured two to four hours after eating.[28]
• Monitor insulin titration through glucose results, generally review type 1 diabetes control every third day during dose adjustment, and investigate overnight glucose when persistent fasting hyperglycaemia suggests a possible Somogyi effect.[29][46]
• Apply hospital monitoring for metabolic instability through documented histories, laboratory assessment, treatment targets and structured follow-up plans.[17][31]In severe inpatient decompensation, increase glucose testing from morning and afternoon checks to as many as six measurements daily.[36]
• Monitor diabetic ketoacidosis through blood glucose, bicarbonate, pH, ketones, serum osmolarity, anion gap, electrolyte and fluid deficits.[38]Use the anion gap, rather than persistent ketonuria, as the principal parameter for follow-up of ketoacidosis resolution.[47]
• Monitor hyperosmolar hyperglycaemic non-ketotic state through hourly glucose measurement during insulin treatment, together with serum sodium, potassium, osmolality, haemodynamic status and the rate of glucose decline.[40][48]
• Monitor perioperative glucose frequently, ordinarily every four to six hours until oral feeding resumes, and more intensively during emergency or complex surgery.[18][49]During the first six to eight postoperative hours, measure capillary glucose every one to two hours and check urine ketones, especially in insulin-dependent patients.[50]

Costing & Financing

The supplied extracts contain no quantified implementation costs, budgets, financing plans, funding gaps, resource-mobilisation mechanisms or economic assumptions for the outpatient or hospital diabetes protocols.[2][16]Most references to resources are operational rather than financial, including laboratory tests, specialist referral, medicines, insulin, monitoring equipment and inpatient clinical infrastructure.[11][38]

• Provide investigations through Ministry of Health hospital services where covered; where necessary, obtain tests privately when a family can afford them.[20][35]
• Maintain access to medicines identified in the Ministry of Health basic medicines list, including glibenclamide and metformin, although no procurement cost, allocation or funding source is specified.[26][27]
• Require hospital equipment and supplies for acute ketoacidosis management, including intravenous fluids, short-acting insulin, infusion pumps or microdrip systems, and, where appropriate, central venous pressure monitoring.[38][39]
• Require glucose-monitoring capacity, insulin-administration methods and relevant hospital facilities for perioperative management, but provide no monetary values or resource-cost estimates.[43]
