I work as a nursing director in a hospice/LTC hospital in KSA, we have 160 bed capacity with an occupancy rate of 90%, I cannot find any research or resource for the exact needed amount of nurse or PCA(patient care assistant). currently, we are doing 1 to 6, 1 to 7 in a 36 patient unit. on the shift there is 2-3 PCA helping out. all of the patients are bedridden, and some have a tracheostomy. any inputs? I feel that the nurses are really struggling..
