NABH HCO Full Accreditation requires hospitals to track mandatory quality indicators across clinical care, infection control, patient safety, nursing, and administrative domains. The minimum data collection period before assessment is 3 continuous months — though 6–12 months of trending data substantially strengthens your evidence. KPIs must be reviewed monthly at the Patient Safety Committee and Quality Council, with analysis and action plans documented in committee minutes. A hospital that collects data but never analyses trends or acts on outliers will fail the QMS chapter regardless of the indicator values themselves. Source: NABH HCO 6th Edition 2024, nabh.co.
Non-negotiable rule: Start tracking KPIs on day one of NABH preparation — the same week you form your committees. Month one data is always your weakest month. The earlier you start, the more improvement trend you can show by assessment time.
NABH KPI categories — mapped to standard chapters
NABH quality indicators are distributed across standard chapters. The QMS chapter (Chapter 10) consolidates mandatory monitoring, but specific KPIs are defined within each clinical chapter. Source: NABH HCO 6th Edition 2024, nabh.co.

|---|---|---|---|
| Clinical quality indicators | COP · AAC · QMS | Quality Council | Monthly + Quarterly |
| Infection control indicators | IPC · QMS | Infection Control Committee · PSC | Monthly |
| Patient safety indicators | PSQ · QMS | Patient Safety Committee | Monthly |
| Medication indicators | MOM · QMS | P&T Committee · PSC | Monthly |
| Nursing quality indicators | COP · HRM · QMS | Nursing Quality Committee | Monthly |

Clinical quality indicators — formulas and benchmarks
These indicators measure overall hospital efficiency and care outcomes. Benchmarks below are standard healthcare quality thresholds — verify current NABH-specific benchmarks against the HCO 6th Edition standards at nabh.co.
| Indicator | Formula | Denominator | Benchmark |
|---|---|---|---|
| Bed Occupancy Rate (BOR) | (Occupied bed days / Available bed days) × 100 | Available bed days in period | ≥ 75% |
| Average Length of Stay (ALOS) | Total inpatient days / Total discharges | Discharges (including deaths) | Specialty-specific |
| LAMA Rate | (LAMA cases / Total discharges) × 100 | Total discharges in period | ≤ 5% |
| Unplanned Readmission within 28 days | (Readmissions / Total discharges) × 100 | Discharges excluding day care | Decreasing trend |
| Patient Satisfaction Score | (Satisfied respondents / Total respondents) × 100 | Min 30 surveys per month | ≥ 80% |
| Complaint Resolution within 7 days | (Complaints resolved ≤7 days / Total complaints) × 100 | Total formal complaints in period | 100% |
Infection control indicators — CAUTI, CLABSI, VAP, hand hygiene
IPC indicators are among the most closely scrutinised during NABH assessment. Rates are reported per 1,000 device-days — not per admission — to enable meaningful comparison across months. Hand hygiene compliance requires direct observation, not self-reporting.
| Indicator | Formula (per 1,000 device-days) | Device days denominator | Benchmark |
|---|---|---|---|
|
Hand Hygiene Compliance
CORE
|
(Compliant observations / Total observations) × 100 | ≥200 obs/month | ≥ 80% |
| CAUTI Rate | (CAUTI cases / Urinary catheter days) × 1,000 | Daily sum of catheterised patients | ≤ 2 per 1,000 |
| CLABSI Rate | (CLABSI cases / Central line days) × 1,000 | Daily sum of central line patients | ≤ 1 per 1,000 |
| VAP Rate | (VAP cases / Ventilator days) × 1,000 | Daily sum of ventilated patients | ≤ 2 per 1,000 |
| Surgical Site Infection (SSI) Rate | (SSI cases / Surgical procedures) × 100 | Total clean surgical cases | ≤ 2% |
| Needle-Stick Injury Rate | (NSI incidents / Staff exposures) × 1,000 | Total staff working days | Decreasing trend |
Patient safety indicators — medication errors, falls, pressure ulcers
Patient safety indicators are reviewed monthly at the Patient Safety Committee. All safety events require incident reports in the hospital's incident reporting system. Assessors cross-check the indicator summary against the incident register to verify that all events were captured.
| Indicator | Formula | Benchmark | Key data source |
|---|---|---|---|
|
Medication Error Rate
CORE
|
(Medication errors / Total drug orders) × 1,000 | Decreasing trend; zero near-miss suppression | Incident register + pharmacy dispensing log |
| Patient Fall Rate | (Patient falls / Patient days) × 1,000 | ≤ 3 per 1,000 patient days | Incident reports + nursing notes |
| Hospital-Acquired Pressure Ulcer Rate | (New pressure ulcers / Patient days) × 1,000 | ≤ 2 per 1,000 patient days | Nursing daily assessment + incident reports |
| Surgical Safety Checklist Compliance | (Completed checklists / Total surgeries) × 100 | 100% | OT record register |
| Consent Documentation Rate | (Consented procedures / Procedures requiring consent) × 100 | 100% | Medical record audit (monthly sample) |
| Transfusion Reaction Rate | (Transfusion reactions / Total transfusions) × 1,000 | Decreasing trend | Blood bank register + incident reports |
HR, nursing, and administrative indicators
These indicators measure workforce compliance, documentation standards, and patient rights. Medical record indicators are typically assessed by monthly audit of a minimum 30-record sample.
| Indicator | Formula | Benchmark |
|---|---|---|
| Staff Training Compliance | (Staff who completed mandatory training / Total staff) × 100 | ≥ 90% quarterly |
| Nursing Hours per Patient Day (NHPPD) | Total nursing care hours / Total patient days | Department-specific |
| Medical Record Completion within 24h of Discharge | (Records complete ≤24h / Total discharges) × 100 | ≥ 90% |
| Doctor-to-Patient Ratio | Clinical doctors on duty / Occupied beds | As per NABH staffing norms |
| Staff Satisfaction Score | (Satisfied staff / Total respondents) × 100 | Annual survey, trend tracking |
| Diet Chart Compliance | (Patients with diet prescription / Total admissions) × 100 | ≥ 90% |
Sampling methods and data collection rules
Assessors review not just the indicator values but the methodology — how data was collected, who collected it, and whether the sample size was adequate. Inconsistent methodology across months is treated as a data quality issue.
Minimum sample sizes
| Indicator type | Minimum monthly sample | Who collects data |
|---|---|---|
| Patient satisfaction survey | 30 completed surveys per month (or 10% of IP discharges, whichever is higher) | Patient relations officer / Quality department |
| Hand hygiene compliance observation | 200 observations per month across all clinical departments | Trained infection control nurse / Quality auditor |
| Medical record audit | 30 records per month (or 10% of discharges) | Medical records officer / Quality Manager |
| Device-day denominators (CAUTI, CLABSI, VAP) | Daily census — all patient-days, no sampling | ICU nurse-in-charge — daily device census log |
| Surgical safety checklist | 100% of all surgeries — no sampling | OT scrub nurse — every case |
| Medication error | 100% capture — all incidents must be reported | Reporting nurse / pharmacist + Quality register |
Denominator rules that assessors check
Two hospitals can report the same numerator but show very different rates if they use different denominators. NABH expects consistent denominator methodology. Critical rules:
- —ALOS denominator: Total discharges must include deaths; excluding deaths inflates the ALOS figure and will be flagged.
- —Device-day denominators: Must be collected every single day — averaging from weekly snapshots underestimates denominator and artificially inflates device-associated infection rates.
- —BOR denominator: Use licensed bed capacity consistently, not actual staffed beds or occupied beds — switching between definitions mid-year creates unexplainable trend breaks.
- —Complaint rate: Count only formal written/registered complaints, not verbal complaints that were resolved at the point of service — but have a separate mechanism to capture and trend informal feedback.
What NABH assessors look for in KPI records
3 months continuous, not 3 months total
Assessors count consecutive months of data, not cumulative data points. April + July + November is 3 months of data but not continuous. A gap in May means your data series restarts from July. Track every month without breaks.
Evidence of committee review — not just data collection
The indicator report must appear in committee minutes — the actual meeting where data was reviewed. Assessors request both the KPI dashboard and the committee minutes for the same period. If the minutes say "data was reviewed" but the KPI sheet wasn't attached or referenced, it creates a documentation gap.
Root cause analysis for outlier months
Every month where an indicator is significantly outside benchmark must have a documented root cause analysis and corrective action plan. An outlier month with no action documented suggests data is collected for compliance only, not for quality improvement — which is exactly the wrong direction for NABH QMS chapter assessment.
Raw data register vs. summary sheet cross-check
Assessors request the source data — the daily hand hygiene observation tally, the incident register, the surgical checklist folder — and manually count to verify the summary figures. A summary showing 87% hand hygiene compliance that cannot be reproduced from the observation tally is a critical finding.
Trend charts — 12 months preferred
Presenting a 12-month trend chart for each major indicator shows that quality management is embedded in how the hospital operates — not activated for assessment. Hospitals that present trend charts to the assessor rather than waiting to be asked create a significantly different impression from those who hand over a folder of monthly data tables.
Frequently asked questions
How many quality indicators does NABH HCO Full Accreditation require?
NABH HCO Full Accreditation specifies mandatory quality indicators across all standard chapters — clinical quality, infection control, patient safety, nursing, and administrative domains. The QMS chapter defines the consolidation requirements. The total number of applicable indicators depends on your hospital's service mix — a hospital with ICU, OT, blood bank, and NICU tracks more indicators than one without these services. Consult the HCO 6th Edition 2024 standards at nabh.co for the complete mandatory indicator list relevant to your hospital type.
How many months of KPI data do you need before NABH assessment?
Assessors require a minimum of 3 continuous months of KPI data before assessment. However, 6–12 months of data substantially strengthens the evidence — it demonstrates trend analysis, response to outliers, and the effect of improvement actions on indicator values. Start KPI tracking on day one of preparation. A hospital presenting 12 months of data with visible improvement trends creates far more compelling evidence than one with the 3-month minimum.

What is the formula for the NABH Hand Hygiene Compliance indicator?
Hand Hygiene Compliance Rate = (Number of compliant hand hygiene observations / Total hand hygiene observations) × 100. Data is collected by trained infection control observers using the WHO 5 Moments for Hand Hygiene framework. Minimum sample: 200 observations per month across all clinical departments. Target benchmark: ≥80% compliance. This is a CORE indicator — consistently low values or absent monthly data will be scored as a major non-conformity under the IPC chapter. Source: NABH HCO 6th Edition 2024, nabh.co.
What is the difference between a hospital-wide KPI and a department-specific KPI in NABH?
Hospital-wide KPIs apply to the entire facility: bed occupancy rate, patient satisfaction score, medication error rate, hand hygiene compliance. Department-specific KPIs apply only to certain services: CAUTI rate (ICU), surgical safety checklist compliance (OT), blood transfusion reaction rate (blood bank), needle-stick injury rate (clinical staff). Hospitals offering ICU, OT, blood bank, or NICU services must track both hospital-wide and applicable department-specific indicators. Source: NABH HCO 6th Edition 2024, nabh.co.
What happens if a NABH KPI benchmark is not met during assessment?
Not meeting a benchmark is not an automatic non-conformity. NABH assesses whether you are measuring accurately, analysing trends, and taking documented corrective action. A hospital with CAUTI rate above benchmark, but with documented root cause analysis, action plans, and improving trend, can still achieve compliance. What guarantees a non-conformity: absent data, inconsistent calculation methods, or data that shows no analysis or response. The QMS chapter requires evidence of committee review and documented follow-up.
Can NABH KPIs be tracked in Excel or does it require software?
Excel is acceptable — NABH does not mandate specific software. However, Excel tracking creates three problems: formula inconsistencies across months, no automated trend charts for committee presentations, and no audit trail when data is edited. Assessors request raw data registers and cross-check them against summary sheets. Any discrepancy between raw tallies and reported percentages is flagged. Dedicated NABH compliance tools automate indicator calculations from raw counts, flag months with missing data, and export committee-ready trend charts.
