Scots nurses say care is being compromised by a staffing crisis in the NHS.
Half of the 3300 staff who responded to a survey by the Royal College of Nursing (RCN) said shortages on their most recent shift had impacted patients.
The research also uncovered concerns over the use of agency staff and the “skill mix” on shifts.
The survey’s preliminary findings were reported by RCN Scotland in a submission to Holyrood’s Health Committee on the 2018/19 draft budget.
More than one third reported the use of bank and agency staff during their most recent shift.
On average, one in eight nurses on that shift were supplied by an agency, the respondents said.
The submissions added: “Respondents also reported insufficient staffing and the impact of this on patient care, with half of those in Scotland reporting patient care was compromised on their last shift.
“When describing what had impacted on the ability to deliver high-quality care, one third reported not enough registered nurses and a quarter reported there were not enough healthcare support workers.
“Nearly half reported they had concerns about the skill mix (which may also include staffing beyond nursing) on their last shift/day of work.”
