The calculation is straightforward:

\\text{Total Nursing Hours} = \\text{Number of patients} \\times \\text{NHPPD}

= 30 \\times 6 = 180 \\text{ nursing hours per day}

This figure is then used to determine the number of nurses required:

\\text{Nurses needed per shift} = \\frac{\\text{Total nursing hours}}{\\text{Hours per shift}}

For example, with 8-hour shifts: \\frac{180}{8} = 22.5 \\approx 23 \\text{ nurses per day (across all shifts)}

NHPPD is a key tool for Head Nurses in workforce planning and budget justification.
