Where I work all falls are investigated. Neuro checks should be done on any unwitnessed fall or if the resident hits their head. The 'root cause' of the fall should be determined. Was the resident incontnent? Do they have pain? Maybe they need a toileting plan or a pain med..maybe a wider bed..maybe bed bolsters? Maybe they are ill..could have an infection and need lab work..if staff isn't completing forms do they need to be educated or reprimanded? We can't prevent all falls but we need to try to prevent injuries from occurring.
