Hospitals in India need different numbers of nurses depending on the department, patient condition and staffing standards they follow. An ICU requires closer nursing supervision than a general ward, while emergency units and operation theatres have their own staffing requirements.
However, there is no single nurse-to-patient ratio in India that applies uniformly to every hospital. SIU, INC and NABH provide different benchmarks, with some figures dating back more than three decades.
The global nursing shortage fell from 6.2 million in 2020 to 5.8 million in 2023. If current trends continue, the shortage is projected to fall to 4.1 million by 2030.
This reference sets SIU, INC and NABH figures side by side for every care area, marks the decades-old ones, and shows how to turn a ratio into a real headcount for hospital manpower planning.
Quick answer
- General ward: 1:6 (SIU, NABH). INC’s 1985 norm is 1:3 in teaching hospitals and 1:5 in non-teaching hospitals.
- HDU: 1:3 (NABH advisory).
- ICU: 1:1 for ventilated patients under all three bodies.
- OT: 2 nurses per table (SIU major theatre, NABH).
- Emergency: 1:1 for ventilated beds and 1:4 for other beds (NABH).
Who Sets Nurse Staffing Norms in India?
Each body works with a different purpose and audience. Knowing that explains why the numbers differ.
1. SIU (Staff Inspection Unit)
The Staff Inspection Unit sits under the Ministry of Finance and was set up in 1964 to check staffing in government bodies. Its nursing norms date to 1991-92 and are followed mainly in Central Government hospitals.
2. INC (Indian Nursing Council)
The Indian Nursing Council regulates nursing education and practice. Its 1985 hospital norms separate teaching hospitals from non-teaching ones and add a leave reserve on top of the bed-based count. These INC staffing norms remain the most quoted reference in nursing exams and college inspections.
3. NABH
NABH is the accreditation board under the Quality Council of India. It published an advisory nurse-to-patient ratio after hospitals and assessors asked for clearer staffing guidance. No single national law fixes one ratio for every private hospital, so all three sets work as benchmarks.
Nurse-to-Patient Ratio in India: NABH, INC and SIU Compared
The nurse-to-patient ratio norms India uses differ most in how they treat each care area.
The figures below come from SIU (1991-92), INC (1985) and the NABH advisory, as summarised in a 2020 review of Indian nurse staffing norms in the Journal of Family Medicine and Primary Care.
1. General Ward
For general wards, the nurse-to-patient ratio in India clusters around 1:6. SIU sets 1:6, and the NABH advisory suggests 1:6 per shift. INC’s 1985 norm is stricter: 1:3 in teaching hospitals and 1:5 in non-teaching hospitals. Some news reports quote INC as 1:6, but the 1985 figures are 1:3 and 1:5.
The ward nurse ratio applies per shift, not per day. A 30-bed ward needs five nurses on the floor in every shift, not five across the whole day.
2. HDU and Special Wards
Only the NABH advisory names HDU, with 1:3 per shift. SIU has no HDU category. Its closest match is the special ward norm of 1:4, which covers paediatrics, burns, neurosurgery, and cardiothoracic units. INC does not list HDU separately.
Pick one document for these units and apply it consistently, so audit files do not show two standards for the same ward.
3. ICU
All three bodies agree on 1:1 for ventilated patients. NABH relaxes this to 1:2 for non-ventilated ICU beds. One nurse cannot safely cover two ventilated patients, so a charge nurse should sit above the bedside count rather than inside it.
Critical care vacancies are also the slowest to fill, so nursing recruitment for ICU roles should start well before a unit opens.
4. Operation Theatre
OT staffing counts nurses per table, not per bed. SIU gives two nurses for each major table, including the recovery room, and one for each minor table. NABH uses two nurses per table per shift. INC does not list OT separately in the sources reviewed. Hospitals with day-care lists should count each functional table on its own.
5. Emergency
SIU ties casualty staffing to daily footfall. It starts with three nurses across 24 hours for up to 100 patients a day, then adds one for every extra 35. Emergency wards attached to casualty fall under its 1:4 norm.
NABH works by bed type instead: 1:1 for ventilated beds and 1:4 for the rest. INC does not list emergency separately. Busy emergency rooms need both views, because footfall peaks do not follow bed counts.
6. Leave Reserve
SIU and INC both add a 30% leave reserve on top of the bed-based count. The NABH advisory does not state one, so hospitals following it should set their own and write it into policy.
How Current Are These Norms?
1. Where the Figures Are Decades Old
The nurse-to-patient ratio in India still rests on documents written before digital charting, day-care surgery, and modern critical care existed.
The 2020 review notes that the SIU, INC and Medical Council of India norms came from professional judgement models and have not been updated. A paper in Indian Pediatrics goes further and calls the SIU deployment norms obsolete given today’s patient complexity.
Two gaps follow from this.
None of the older norms accounts for patient acuity, bed occupancy or length of stay. And a ratio written for a 1990s ward may understate the load on a nurse running infusion pumps, monitors and electronic records in the same shift.
2. What Newer Workload Studies Show
An AIIMS time-and-motion study in a tertiary medicine ICU used the WHO workload indicators method. It recommended a ratio slightly above one nurse per bed each shift. That suggests the 1:1 figure in all three norms is a floor for heavy ICU workloads, not a ceiling.
How to Convert a Ratio Into a Nurse Headcount
To convert the nurse-to-patient ratio in India into a headcount, use three steps:
- Nurses per shift = beds ÷ ratio denominator.
- Nurses per day = nurses per shift × shifts (usually 3).
- Total roster = nurses per day × (1 + leave reserve).
Example 1: a 30-bed general ward at 1:6 needs 5 nurses per shift. That is 15 across three shifts, or 19.5 with a 30% leave reserve, which rounds up to 20 nurses.
Example 2: a 10-bed ICU with all beds ventilated at 1:1 needs 10 nurses per shift, 30 per day, and 39 with a 30% reserve.
Add supervisory roles on top. The NABH advisory suggests one infection control nurse for every 100 beds.

Nurse Requirement Calculator
The calculator applies the nurse-to-patient ratio in India from your chosen norm to your bed count. Enter bed count, unit type, norm (SIU, INC or NABH), and shifts per day.
The first result, nurses needed per shift, appears instantly. The full roster unlocks after you share a name, hospital, and work email. It includes the leave reserve, charge nurse cover, and a shift-wise split.
What a Ratio Gap Does to a Hospital
A gap against the nurse-to-patient ratio in India shows up first in overtime, then in sick leave, then in resignations. Hospitals running at the bare minimum lose nurses faster, so nurse retention strategies belong in the same plan as the ratio.
Closing the gap through hiring also takes longer than most plans assume, because registration checks and notice periods stretch the timeline.
Which Norm Should a Hospital Follow?
- Central Government and public hospitals: SIU is the working reference.
- NABH-accredited or applying hospitals: use the NABH advisory as the minimum, and keep INC’s leave reserve for roster planning.
- Teaching hospitals: INC’s 1:3 ward norm is the stricter benchmark for college inspections.
- Private hospitals: adopt one norm, then raise it for high-acuity units using workload data.
Whatever the choice, the nurse-to-patient ratio in India a hospital adopts should be written into its staffing policy with a review date. That gives auditors a clear basis and gives HR a hiring target.
The NABH advisory is a guide, not a legal mandate. Check the latest NABH circular before using it in an audit file.
Conclusion
The nurse-to-patient ratio in India depends on whether a hospital follows SIU, INC, or NABH, and the older norms need a workload check before they are used for ICU or emergency planning.
Use the area-wise figures above as a starting point, apply the leave reserve, and review the numbers each year.

FAQs
1. What is the nurse-to-patient ratio in India for a general ward?
SIU and NABH guidance both point to 1:6 per shift. INC’s 1985 norm is stricter at 1:3 for teaching hospitals and 1:5 for non-teaching hospitals.
2. What is the NABH nurse ratio for ICU?
The NABH advisory suggests 1:1 for ventilated ICU beds and 1:2 for non-ventilated beds. HDU is 1:3.
3. Is the nurse ratio legally binding in India?
No single national law fixes one ratio for every hospital. SIU, INC and NABH figures work as benchmarks for government hospitals, nursing colleges and accreditation.
4. Are SIU and INC norms outdated?
Published reviews describe them as based on professional judgement and not updated. SIU dates to 1991-92 and INC to 1985, so hospitals should check them against actual workload, especially in ICU and emergency.
5. How many nurses does a hospital need in total?
Divide beds by the ratio to get nurses per shift, multiply by three shifts, then add a leave reserve of about 30%. Add supervisors and infection control nurses on top.
