Measuring without a ruler: Limited data to characterize the relationship between physician assistant/nurse practitioner staffing and emergency department performance.

ABSTRACT:

Objective

Physician assistant (PA) and nurse practitioner (NP) staffing is increasingly common in emergency departments (EDs), with variable physician supervision. We examined the feasibility of using publicly reported metrics as a measure of ED performance by staffing model.

Methods

We classified a convenience sample of 915 EDs by staffing model using the National Emergency Department Inventory-USA 2016 and a follow-up survey. Staffing models included 24/7 attending coverage with PAs/NPs, 24/7 attending coverage without PAs/NPs, and PAs/NPs without 24/7 attending coverage. We linked EDs with Hospital Compare data to examine availability of metrics and compared metric performance by staffing model. We used regression modeling to examine the independent relationship between staffing model and ED performance after adjusting for ED characteristics.

Results

Of 915 EDs surveyed, 767 (83%) responded and 436 (48%) had complete staffing data and any Hospital Compare data. The 216 EDs without any Hospital Compare data more frequently had no 24/7 attending coverage, were smaller, and were more often rural. Of 5 clinical metrics, 3 had data from < 100 EDs (range: 2%-21%), and 2 had data from 0 EDs. Of the 5 clinical metrics, only median time-to-ECG had enough data for analysis and found no difference among staffing models. Among the 3 process metrics, only time to discharge was significantly faster in EDs with any PA/NP staffing.

Conclusion

Many EDs in our national sample lacked sufficient Hospital Compare data to evaluate performance, likely because of lower patient volumes for condition-specific metrics. Alternative strategies to measure quality of care delivery in these settings should be developed.

Project description:Background Many countries are looking for ways to increase nurse practitioner (NP) and physician assistant/associate (PA) deployment. Countries are seeking to tackle the pressing issues of increasing healthcare demand, healthcare costs, and medical doctor shortages. This article provides insights into the potential impact of various policy measures on NP/PA workforce development in the Netherlands. Methods We applied a multimethod approach study using three methods: 1) a review of government policies, 2) surveys on NP/PA workforce characteristics, and 3) surveys on intake in NP/PA training programs. Results Until 2012, the annual intake into NP and PA training programs was comparable to the number of subsidized training places. In 2012, a 131% increase in intake coincided with extending the legal scope of practice of NPs and PAs and substantially increasing subsidized NP/PA training places. However, in 2013, the intake of NP and PA trainees decreased by 23% and 24%, respectively. The intake decreased in hospitals, (nursing) home care, and mental healthcare, coinciding with fiscal austerity in these sectors. We found that other policies, such as legal acknowledgment, reimbursement, and funding platforms and research, do not consistently coincide with NP/PA training and employment trends. The ratios of NPs and PAs to medical doctors increased substantially in all healthcare sectors from 3.5 and 1.0 per 100 full-time equivalents in medical doctors in 2012 to 11.0 and 3.9 in 2022, respectively. For NPs, the ratios vary between 2.5 per 100 full-time equivalents in medical doctors in primary care and 41.9 in mental healthcare. PA-medical doctor ratios range from 1.6 per 100 full-time equivalents in medical doctors in primary care to 5.8 in hospital care. Conclusions This study reveals that specific policies coincided with NP and PA workforce growth. Sudden and severe fiscal austerity coincided with declining NP/PA training intake. Furthermore, governmental training subsidies coincided and were likely associated with NP/PA workforce growth. Other policy measures did not consistently coincide with trends in intake in NP/PA training or employment. The role of extending the scope of practice remains to be determined. The skill mix is shifting toward an increasing share of medical care provided by NPs and PAs in all healthcare sectors.

Project description:BACKGROUND:The delivery of emergency, trauma, critical, and intensive care services requires coordination among all members of the care team. Perceived teamwork and role clarity may vary among physicians (MDs) and nurse practitioners (NPs). PURPOSE:To examine differences in perceived roles and responsibilities of NPs and MDs practicing in emergency, trauma, critical, and intensive care. METHODS:Secondary Analysis of the National Survey of Emergency, Intensive, and Critical Care Nurse Practitioners and Physicians, a cross-sectional national survey of clinicians. Mail survey of randomly selected stratified cross-sectional samples of MDs and NPs drawn from national lists of clinicians in eligible specialties working in emergency, trauma, intensive, and critical care units in the United States. 814 clinicians (351 NPs and 463 MDs) were recruited from national by postal mail survey. Our initial sample included n = 2,063 clinicians, n = 1,031 NPs and n = 1,032 MDs in eligible specialties. Of these, 63.5% of NPs and 70.1% of MDs completed and returned the survey excluding those who were ineligible due to lack of current practice in a relevant specialty. FINDINGS:NPs in ICU/CCU are more likely to be female and report working fewer hours than do MDs and provide direct care to more patients. 55% of NPs and 82% of MDs agree that their individual role in their unit is clear (p < .001); 34% of MDs and 42% of NPs agree that their unit is an example of excellent team work among professionals (p = 0.021); 41% of MD and 37% of NP clinicians (p = 0.061) agree that their teams are "prepared to provide outstanding care in a crisis or disaster." Perceived role clarity was significantly associated with increased perceptions of excellent teamwork and disaster preparedness. DISCUSSION:At the time of this survey, and majority of NPs and MDs working in emergency, critical and intensive care did not agree that their teams were prepared for a crisis or disaster. Leaders of health organizations should encourage teamwork and professional role clarity to assist units to perform effectively in emergency and disaster preparedness.
