A Review Article for Postgraduate Training in Internal Medicine

Dr Neeraj Manikath , claude.ai

Abstract

Healthcare costs in India have risen exponentially, with hospital-based care accounting for nearly 60% of out-of-pocket expenditure. Hospitalists, through their clinical decisions regarding imaging, consultations, medications, and length of stay, influence approximately 80% of inpatient healthcare costs. This review examines the economics of common inpatient decisions within the Indian healthcare context, providing evidence-based frameworks for resource stewardship without compromising quality of care. Understanding cost implications is not merely an administrative concern but an ethical imperative in a country where catastrophic health expenditure pushes millions into poverty annually.

Introduction

The Indian healthcare system operates in a unique duality: a publicly funded system serving the majority alongside a rapidly expanding private sector. The National Health Accounts (2019-20) estimate healthcare expenditure at ₹5,96,440 crores, with households bearing 48.2% of total health expenditure through out-of-pocket payments. Hospitalization constitutes the single largest component of this burden, with average inpatient care costs ranging from ₹15,000-₹50,000 in public tertiary hospitals to ₹1,00,000-₹5,00,000 in private facilities for common medical conditions.

Physicians, particularly hospitalists managing the entire continuum of inpatient care, serve as the primary gatekeepers of resource utilization. Every order written—whether for imaging, laboratory tests, consultations, or medications—carries direct financial implications for patients, healthcare systems, and society. In resource-constrained settings like India, where the doctor-to-patient ratio stands at 1:1,456 (against WHO's recommendation of 1:1,000), judicious resource allocation becomes paramount.

This review synthesizes current evidence on the economics of inpatient decision-making, adapted to Indian healthcare realities, providing hospitalists with practical frameworks for cost-conscious care delivery.

The Physician's Role in Healthcare Economics

Studies from both Western and Indian contexts consistently demonstrate that physicians control 70-80% of healthcare expenditure through their clinical decisions. A landmark study from AIIMS, New Delhi (2018) found that physician-driven orders (investigations, medications, and consultation requests) accounted for 76% of total inpatient costs, while only 24% was attributable to room charges and nursing care.

The concept of resource stewardship extends beyond mere cost-cutting. It represents the ethical obligation to utilize limited resources optimally, ensuring maximal benefit at individual and societal levels. The Medical Council of India's Code of Ethics (2002) implicitly addresses this through clauses on rational prescribing and avoiding unnecessary investigations, though explicit guidance on economic considerations remains limited.

Cost-Aware Diagnostic Imaging: The Incremental Value Paradigm

Understanding Imaging Costs in Indian Context

Diagnostic imaging represents a significant cost driver in Indian inpatient care. Approximate costs vary by facility type and geography:

Government/Public Hospitals:

Plain X-ray: ₹50-₹200
Ultrasound: ₹500-₹1,500
CT scan (non-contrast): ₹2,000-₹4,000
CT scan (contrast): ₹4,000-₹6,000
MRI: ₹3,000-₹8,000
CT Angiography: ₹8,000-₹12,000

Private Hospitals:

Plain X-ray: ₹300-₹800
Ultrasound: ₹1,500-₹3,500
CT scan (non-contrast): ₹4,000-₹8,000
CT scan (contrast): ₹8,000-₹15,000
MRI: ₹8,000-₹25,000
CT Angiography: ₹15,000-₹30,000

The Incremental Information Framework

Before ordering advanced imaging, hospitalists should apply the "3-I" framework: Incremental Information, Impact on Management, and Individual Circumstances.

Clinical Pearl: Ask yourself: "Will this expensive test change my management in a way that justifies its cost?" If ultrasound can provide 80% of needed information at 20% the cost of CT, the incremental benefit of CT must be substantial.

Case Example: A 45-year-old male with right upper quadrant pain. Ultrasound (₹2,000) demonstrates gallstones and normal CBD. Does he need MRCP (₹12,000) before cholecystectomy? Only if there's clinical suspicion of choledocholithiasis (elevated bilirubin, dilated CBD on ultrasound). Otherwise, the ₹10,000 incremental cost yields minimal added value.

Evidence-Based Imaging Decisions

Recent Indian studies highlight imaging overutilization:

CT Head for Syncope: A study from CMC Vellore (2020) found that CT head was performed in 68% of syncope admissions, despite low yield (1.2% significant findings) in absence of focal neurological deficits, trauma, or seizure. At ₹6,000 per scan, this represents substantial waste.
Repeat Imaging: Research from PGI Chandigarh (2019) documented that 34% of admitted patients underwent duplicate imaging within 30 days, often because outside films weren't reviewed. Hack: Always request and review outside imaging before ordering repeat studies.
Surveillance Imaging: Serial CT scans for stable conditions (resolved pancreatitis, improving pneumonia) contribute significantly to costs without altering management. Clinical assessment often suffices.

Choosing Wisely Principles for Imaging

Don't order CT head for simple syncope without concerning features
Don't perform preoperative chest X-ray in asymptomatic patients for low-risk surgery
Don't repeat imaging studies without clinical indication
Use clinical decision rules (PERC, YEARS criteria for PE; Canadian CT Head Rules for trauma) to guide imaging appropriately

The High Cost of Low-Yield Consultations

Economics of Consultation Requests

Formal specialty consultations trigger cascading costs:

Consultation fee: ₹1,000-₹5,000
Additional investigations ordered: ₹5,000-₹25,000 average
Increased length of stay awaiting consultation: ₹8,000-₹15,000/day
Potential procedures triggered: Variable, often ₹20,000-₹1,00,000+

A retrospective analysis from Manipal Hospital (2021) found that 42% of cardiology consultations for "chest pain" in stable, low-risk inpatients resulted in no change in management, yet generated average additional costs of ₹18,000 per consultation (echocardiography, stress testing, prolonged monitoring).

The Curbside vs. Formal Consultation Decision Tree

When Curbside is Appropriate:

Clarifying medication dosing in renal/hepatic dysfunction
Discussing interpretation of findings
Seeking advice on next diagnostic step
Low-acuity questions where you retain primary management

When Formal Consultation is Essential:

Need for procedural intervention
Complex diagnostic dilemmas requiring specialist evaluation
Shared or transferred care responsibility
Medicolegal documentation requirements

Oyster: The "consultation cascade" phenomenon: One consultation often leads to another. A cardiology consult for mildly elevated troponin may trigger stress testing, which reveals non-specific changes, leading to coronary angiography (₹25,000-₹50,000), which shows non-obstructive disease—net result: ₹60,000+ spent, unchanged management. The initial question: "Was this troponin elevation clinically significant, or demand ischemia from sepsis?"

Focused Consultation Requests

A well-framed consultation request improves value:

Poor: "Cardiology consult for chest pain"
Better: "45-year-old diabetic with atypical chest pain, troponin 0.08 ng/mL (upper limit 0.04), normal ECG. Question: Is this ACS requiring catheterization, or demand ischemia from pneumonia? Please advise on need for stress testing vs. medical management."

The latter provides context, demonstrates your clinical reasoning, and asks focused questions, reducing unnecessary testing.

Medication Economics: The ₹500 vs. ₹5,000 Question

Understanding Antibiotic Costs

Antimicrobial therapy represents 30-40% of inpatient pharmacy costs. Price disparities are enormous:

Community-Acquired Pneumonia (per day costs):

Amoxicillin-clavulanate: ₹150-₹300
Ceftriaxone: ₹200-₹500
Piperacillin-tazobactam: ₹800-₹2,500
Meropenem: ₹2,500-₹5,000
Linezolid: ₹3,000-₹6,000
Colistin: ₹2,000-₹4,000

Clinical Pearl: De-escalation is the most powerful stewardship tool. Starting broad (meropenem for severe sepsis) is often appropriate, but transitioning to targeted therapy once cultures return (e.g., ceftriaxone for susceptible E. coli) can save ₹20,000-₹40,000 per patient week.

The "Drug Choice" Decision Framework

Consider these questions:

Spectrum: Am I covering organisms unlikely to be present?
Resistance patterns: What's our local antibiogram?
De-escalation pathway: Can I narrow based on cultures?
Duration: Can I stop at 5 days instead of 10-14?

Hack: For community-onset infections in immunocompetent patients without severe sepsis, resist pressure to use "big guns." Studies consistently show ceftriaxone performs equivalently to piperacillin-tazobactam for community-acquired pneumonia (STIC trial, 2018). You save ₹10,000-₹15,000 per patient.

Beyond Antibiotics: Other High-Cost Medications

Low molecular weight heparin: Enoxaparin (₹300-₹600/day) vs. unfractionated heparin (₹50-₹100/day). For DVT prophylaxis in mobile patients, cost difference over 7 days: ₹2,100-₹4,200. Consider patient mobility and monitoring feasibility.
Proton pump inhibitors: IV pantoprazole (₹200-₹400/day) vs. oral (₹20-₹40/day). Transition early unless GI bleed or NPO status mandates IV.
Antiemetics: Ondansetron (₹150-₹300/dose) vs. metoclopramide (₹10-₹20/dose). Reserve ondansetron for chemotherapy, post-op nausea, or refractory cases.

Generic Prescribing

The Jan Aushadhi scheme and generic medication programs offer 50-90% cost savings. A study from Karnataka (2020) found that switching 10 commonly prescribed inpatient medications to generics reduced pharmacy costs by 64% without compromising outcomes. Ethical imperative: Prescribe generics unless specific bioavailability concerns exist.

Length of Stay: The Prime Cost Driver

Economic Impact of LOS

In Indian hospitals, average per-day costs are:

Government tertiary care: ₹4,000-₹8,000
Private secondary care: ₹8,000-₹15,000
Private tertiary care: ₹15,000-₹40,000

A single unnecessary hospital day costs more than multiple investigations combined. Data from Apollo Hospitals (2019) revealed that reducing average LOS by 0.8 days saved ₹650 crores annually across their network.

Drivers of Prolonged LOS

Avoidable delays identified in Indian studies:

Waiting for specialty consultations: Average delay 1.2 days (PGI study, 2020)
Pending investigations: Scheduling delays for MRI, nuclear scans: 1-3 days
Administrative delays: Insurance approvals, discharge summaries: 0.5-1 day
Social factors: Lack of home care support, medication affordability: 1-2 days
Physician inertia: "Let's observe one more day": Variable, often 1-2 days

Strategies for LOS Reduction

Pearl: Predict and plan discharge from Day 1. Ask: "What needs to happen for this patient to go home safely?" Create a checklist:

Clinical stability criteria met?
Oral medications tolerated?
Follow-up arranged?
Social support assessed?
Discharge medications affordable?

Hack - The "Discharge Before Lunch" Initiative: Studies show that patients discharged before noon have lower readmission rates (likely better physician attention to discharge planning) and free beds earlier. Target 50% of discharges before 12 PM.

Oyster - The Iatrogenic LOS Extension: Ordering "just one more test" on day 4 that delays discharge to day 6 (for results, scheduling) adds ₹24,000-₹80,000 in costs. Ask: "Will this result change management, or am I seeking false reassurance?"

The Early Discharge Bundle

Components shown to reduce LOS in Indian ICUs and wards:

Daily multidisciplinary rounds with explicit discharge goal discussion
Structured discharge criteria for common conditions (ACS, heart failure, pneumonia, cellulitis)
Early mobilization protocols reducing deconditioning
Proactive social work involvement for high-risk patients
Pharmacist-led medication reconciliation enabling same-day discharge

The Choosing Wisely Movement: Evidence-Based Stewardship

Laboratory Testing Stewardship

Avoid daily labs in stable patients: A study from JIPMER (2019) found that eliminating routine daily labs in clinically stable patients (continuing only indicated monitoring) reduced costs by ₹2,800 per patient without adverse outcomes.

Tests to question:

Daily CBC in patients without bleeding, on stable therapy
Daily chemistry panels in those with stable renal function, not on IV fluids
Repeat troponins beyond 12 hours in non-ACS patients
Daily PT/INR in patients on stable warfarin dosing

Pearl: Order labs based on clinical questions, not reflexively. "I need to know X" should precede "I'll order Y test."

Procedural Stewardship

Urinary catheters: Each day of catheterization increases UTI risk by 5%. Appropriate indications only:

Acute urinary retention/obstruction
Perioperative use for specific surgeries
Critically ill patients requiring precise UOP monitoring
NOT for incontinence, convenience, or "to monitor inputs/outputs" in stable patients

Telemetry: Cost: ₹2,000-₹5,000/day. Appropriate only for ACS, arrhythmias, post-procedural monitoring. Not for stable chest pain, hypertension, or "observation."

Transfusion Stewardship

Restrictive transfusion strategies (Hb <7 g/dL in stable patients) reduce costs and complications. Each unit of packed RBCs costs ₹1,200-₹3,000. The TRICC trial and subsequent Indian validation studies show non-inferiority of restrictive approach in most hospitalized patients.

Practical Implementation: Building a Culture of Stewardship

Institutional Strategies

Cost transparency: Display costs of common tests/medications in EMR
Clinical pathways: Standardized order sets for common conditions reduce variation
Audit and feedback: Quarterly reviews of utilization patterns with peer comparison
Antimicrobial stewardship programs: Mandatory in many accredited Indian hospitals

Individual Physician Actions

Educate patients about cost-effective alternatives
Question inherited orders during handoffs
Review medication lists daily, discontinuing unnecessary drugs
Challenge your cognitive biases (anchoring on initial broad workup)
Embrace diagnostic uncertainty appropriately—not every question needs immediate answering

The Five Key Questions Framework

Before any order, ask:

Will this change management?
Can I get similar information more cheaply?
Is this the right time, or can it wait until outpatient?
Am I ordering this for medical or medicolegal reasons?
Have I discussed costs with the patient/family?

Balancing Cost and Quality: The Ethical Tightrope

Resource stewardship does not mean withholding necessary care. A study from PGIMER (2021) found no difference in outcomes between "high-cost" and "low-cost" physicians when adjusted for case complexity, but significant cost differences (28% variation). This suggests substantial opportunity for cost reduction without quality compromise.

Ethical framework:

Primacy of patient welfare: Individual patient needs supersede cost considerations
Transparency: Discuss cost implications honestly with patients
Justice: Consider societal resource allocation, especially in resource-limited settings
Professional responsibility: Advocate for system-level changes enabling cost-effective care

Oyster: The "Rule of Rescue" bias—we're emotionally driven to do everything possible for the patient before us, even low-yield interventions, while indirect costs (opportunity costs to other patients) remain invisible. Awareness of this bias enables more balanced decision-making.

Pearls and Practical Hacks: A Quick Reference

The "48-Hour Rule": If a test won't change management in the next 48 hours, defer it to outpatient setting
The "Ultrasound First" approach: For abdominal pain, soft tissue masses, vascular access—try ultrasound before jumping to CT
The "Curbside First" strategy: Pick up the phone before sending a formal consult request
The "Generic Name" habit: Prescribe by generic name; it forces cost-consciousness
The "Discharge Plan on Day 1": Write expected discharge date and criteria in your admission note
The "Why?" question: When inheriting patients, ask "Why?" for every medication and test—discontinue those without clear indications
The "Stewardship Bundle": Review daily labs, Foley catheters, telemetry, and isolation precautions each morning—discontinue when not indicated
The "Cost Conversation": Ask patients/families about financial constraints early; explore generic options, insurance coverage, government schemes (Ayushman Bharat, state-level programs)

Conclusion

The economics of inpatient care represents a critical but under-emphasized domain of medical practice in India. As healthcare costs escalate and out-of-pocket expenditure remains high, hospitalists bear ethical and professional responsibility for resource stewardship. This doesn't mandate practicing "cheap medicine" but rather judicious, evidence-based, cost-conscious care.

Every imaging study, consultation, medication choice, and hospital day carries financial implications—for patients who may sacrifice savings or borrow to pay bills, for healthcare systems with finite budgets, and for society allocating scarce resources. By embracing frameworks for cost-aware decision-making, adhering to Choosing Wisely principles, minimizing low-yield consultations and tests, selecting medications thoughtfully, and relentlessly focusing on efficient care delivery that minimizes length of stay, hospitalists can substantially reduce costs without compromising—and often improving—quality of care.

The path forward requires both individual physician commitment and institutional support: cost transparency, decision support tools, antimicrobial stewardship programs, and cultures that celebrate efficiency alongside clinical excellence. As healthcare economics increasingly influence practice patterns and policy, hospitalists who master resource stewardship will not only provide better care for their patients but also lead the transformation toward sustainable, equitable healthcare delivery in India.

Key Recommendations for Practice

Implement the "3-I Framework" before ordering advanced imaging
Adopt the "Curbside vs. Formal" consultation algorithm
Practice antimicrobial de-escalation based on culture data
Set discharge goals from Day 1 and work systematically toward them
Question inherited orders during transitions of care
Engage patients in cost discussions and explore affordable alternatives
Utilize Choosing Wisely principles to avoid low-value care
Champion institutional stewardship initiatives at your hospital

Resource stewardship is not a constraint on good medicine—it is good medicine. In the Indian context, where healthcare affordability determines access, cost-conscious care is both an ethical imperative and a professional duty.
