Research has been done on nurse staffing and patient outcomes; the impact of organizational characteristics on nurse staffing patterns, patient outcomes, and costs; and the impact of nurses' experience on patient outcomes. The research indicates that nurse staffing has a definite and measurable impact on patient outcomes, medical errors, length of stay, nurse turnover, and patient mortality. Also, acuity and severity data is routinely the evidential basis most frequently cited by staff when recommending clinical staffing changes.</p>\n</div></div>\n    \n    \n    \n    <div id=\"requirements\"><b>Criteria <a href=\"https://hl7.org/fhir/versions.html#std-process\" title=\"Normative Content\" class=\"normative-flag\">N</a>:</b></div>\n    \n    <table id=\"statements\" class=\"grid dict\">\n        \n        <tr>\n            <td style=\"padding-left: 4px;\">\n            AS.6.6#01\n            </td>\n            <td style=\"padding-left: 4px;\">\n            SHOULD\n            \n                \n            \n            \n            \n            </td>\n            <td style=\"padding-left: 4px;\" class=\"requirement\">\n                <div><p>The system SHOULD provide the ability to capture (i.e., collect) data to support the patient acuity/severity processes for illness/risk-based adjustment of resources.</p>\n</div>\n                \n            </td>\n        </tr>\n        \n        <tr>\n            <td style=\"padding-left: 4px;\">\n            AS.6.6#02\n            </td>\n            <td style=\"padding-left: 4px;\">\n            MAY\n            \n                \n            \n            \n            \n            </td>\n            <td style=\"padding-left: 4px;\" class=\"requirement\">\n                <div><p>The system MAY provide the ability to extract and transmit (i.e., export) data to support the patient acuity/severity processes for illness/risk-based adjustment of resources.</p>\n</div>\n                \n            </td>\n        </tr>\n        \n        <tr>\n            <td style=\"padding-left: 4px;\">\n            AS.6.6#03\n            </td>\n            <td style=\"padding-left: 4px;\">\n            MAY\n            \n                \n            \n            \n            \n            </td>\n            <td style=\"padding-left: 4px;\" class=\"requirement\">\n                <div><p>The system MAY render a prompt for the user to provide key data needed to support acuity/severity processes.</p>\n</div>\n                \n            </td>\n        </tr>\n        \n        <tr>\n            <td style=\"padding-left: 4px;\">\n            AS.6.6#04\n            </td>\n            <td style=\"padding-left: 4px;\">\n            MAY\n            \n                \n            \n            \n            \n            </td>\n            <td style=\"padding-left: 4px;\" class=\"requirement\">\n                <div><p>The system MAY provide the ability to determine patient acuity, and/or severity levels.</p>\n</div>\n                \n            </td>\n        </tr>\n        \n    </table>\n</div>"
