Quality of diabetes care in family medicine practices: influence of nurse-practitioners and physician's assistants

Teamwork and its impact on chronic disease clinical outcomes in primary care: a systematic review and meta-analysis

OBJECTIVE

Teamwork positively affects staff performance and patient outcomes in chronic disease management. However, there is limited research on the impact of specific team components on clinical outcomes. This review aims to explore the impact of teamwork components on key clinical outcomes of chronic diseases in primary care.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

This systematic review and meta-analysis conducted searching EMBASE, PubMed, Cochrane Central Register of Controlled Trials. Studies included must have at least one teamwork component, conducted in primary care for selected chronic diseases, and report an impact of teamwork on clinical outcomes. Mean differences and 95% confidence intervals were used to determine pooled effects of intervention.

RESULTS

A total of 54 studies from 1988 to 2021 were reviewed. Shared decision-making, roles sharing, and leadership were missing in most studies. Team-based intervention showed a reduction in mean systolic blood pressure (MD = 5.88, 95% CI 3.29-8.46, P= <0.001, I2 = 95%), diastolic blood pressure (MD = 3.23, 95% CI 1.53 to 4.92, P = <0.001, I2 = 94%), and HbA1C (MD = 0.38, 95% CI 0.21 to 0.54, P = <0.001, I2 = 58%). More team components led to better SBP and DBP outcomes, while individual team components have no impact on HbA1C. Fewer studies limit analysis of cholesterol levels, hospitalizations, emergency visits and chronic obstructive pulmonary disease-related outcomes.

CONCLUSION

Team-based interventions improve outcomes for chronic diseases, but more research is needed on managing cholesterol, hospitalizations, and chronic obstructive pulmonary disease. Studies with 4-5 team components were more effective in reducing systolic blood pressure and diastolic blood pressure. Heterogeneity should be considered, and additional research is needed to optimize interventions for specific patient populations.

Primary Care Nurse Practitioner Burnout and ED Use and Hospitalizations Among Chronically Ill Medicare Beneficiaries

Nurse practitioners (NPs) represent the fastest-growing workforce of primary care clinicians in the United States. Their numbers are projected to grow in the near future. The NP workforce can help the country meet the rising demand for care services due to the aging population and increasing chronic disease burden. Yet, increased burnout among these clinicians may affect their ability to deliver high-quality, safe care. We investigated how NP burnout in primary care practices affects patient outcomes, including emergency department (ED) use and hospitalizations, among older adults with chronic conditions. In 2018-2019, we collected survey data from 1244 primary care NPs from 6 geographically diverse states on their burnout and merged the survey data with data from Medicare claims on ED use and hospitalizations among 467 466 older adults with chronic conditions. 26.3% of NPs reported burnout. Using logistic regression models, we found that with a 1-unit increase in the standardized burnout score, the odds of an ED visit increased by 2.8% (OR = 1.028; P-value = .035); Ambulatory Care Sensitive Conditions (ACSC) ED visit by 3.2% (OR = 1.032; P-value = .019); hospitalization by 3.9% (OR = 1.039; P-value = .001); and ACSC hospitalization by 6.2% (OR = 1.062; P-value = .001). Our findings indicate that if chronically ill older adults receive care in primary care practices with higher NP burnout rates they are more likely to use EDs and hospitals. Policy and practice efforts, such as improving NP working conditions, should be undertaken to reduce NP burnout in primary care practices to potentially prevent acute care use.

The effect of team-based care practice on productivity for family physicians

ABSTRACT

About 60% of family physician practices employ PAs and/or NPs but gaps exist in the knowledge of the clinical effects on physician-PA and physician-NP teams. This review summarizes and comments on the significance of a recent report from the American Board of Family Medicine that compares the scope of practice of family physicians for family physicians practicing with either a PA, NP, or both.

Patient Acceptance of Nurse Practitioners and Physician Assistants in Rheumatology Care

OBJECTIVE

This study sought to assess whether patients with autoimmune disease would accept advanced practice providers (APPs) as an option to fill the growing shortage of rheumatologists.

METHODS

We administered a cross-sectional survey to 500 patients or parents of children who reported having been diagnosed with qualifying autoimmune conditions and who had seen their primary rheumatology providers in the past 6 months. Respondents self-reported whether their primary providers were rheumatologists or APPs. Our analysis compared the attitude and experience of the patients whose primary rheumatology providers were APPs with those of patients whose primary providers were rheumatologists.

RESULTS

Of respondents, 36.8% reported having APPs as primary rheumatology providers. Patients of APPs were significantly more likely to arrive at their provider's office in 15 minutes or less (p < 0.01) and to be able to schedule routine and urgent appointments sooner (p = 0.02, 0.05). There were no significant differences for overall patient experience of care between provider types. Most patients rated their providers highly, but those who saw rheumatologists rated their providers significantly higher (p < 0.01). APP patients were significantly more likely than rheumatologist patients to prefer to see APPs over rheumatologists (p < 0.01) and to recommend APPs (p < 0.01).

CONCLUSIONS

APPs may improve access to care, and regardless of provider type, patients rated their overall experience of care similarly. Overall, patient attitudes toward APPs were positive regardless of provider type, although APP patients held more positive overall attitudes toward APPs than did rheumatologist patients.

Relationship of Clinician Care Team Composition and Diabetes Quality Outcomes

The objective was to determine if a greater proportion of physician full-time equivalent (FTE%) relative to nurse practitioners/physician assistants (NPs/PAs) on care teams was associated with improved individual clinician diabetes quality outcomes. The authors conducted a retrospective cross-sectional study of 420 family medicine clinicians in 110 care teams in a Midwest health system, using administrative data from January 1, 2017 to December 31, 2017. Poisson regression was used to examine the relationship between physician FTE% and the number of patients meeting 5 criteria included in a composite metric for diabetes management (D5). Covariates included panel size, clinician type, sex, years in practice, region, patient satisfaction, care team size, rural location, and panel complexity. Of the 420 clinicians, 167 (40%) were NP/PA staff and 253 (60%) were physicians. D5 criteria were achieved in 37.9% of NP/PA panels compared with 44.5% of physician panels (P < .001). In adjusted analysis, rate of patients achieving D5 was unrelated to physician FTE% on the care team (P = .78). Physicians had a 1.082 (95% confidence interval 1.007-1.164) times greater rate of patients with diabetes achieving D5 than NPs/PAs. Clinicians at rural locations had a .904 (.852-.959) times lower rate of achieving D5 than those at urban locations. Physicians had a greater rate of patients achieving D5 compared with NPs/PAs, but physician FTE% on the care team was unrelated to D5 outcomes. This suggests that clinician team composition matters less than team roles and the dynamics of collaborative care between members.

Processes and outcomes of diabetes mellitus care by different types of team primary care models

Background

Team care improves processes and outcomes of care, especially for patients with complex medical conditions that require coordination of care. This study aimed to compare the processes and outcomes of care provided to older patients with diabetes by primary care teams comprised of only primary care physicians (PCPs) versus team care that included nurse practitioners (NPs) or physician assistants (PAs).

Methods

We studied 3,524 primary care practices identified via social network analysis and 306,741 patients ≥66 years old diagnosed with diabetes in or before 2015 in Medicare data. Guideline-recommended diabetes care included eye examination, hemoglobin A1c test, and nephropathy monitoring. High-risk medications were based on recommendations from the American Geriatrics Society Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. Preventable hospitalizations were defined as hospitalizations for a potentially preventable condition.

Results

Compared with patients in the PCP only teams, patients in the team care practices with NPs or PAs received more guideline-recommended diabetes care (annual eye exam: adjusted odds ratio (aOR): 1.04 (95% CI: 1.00–1.08), 1.08 (95% CI: 1.03–1.13), and 1.10 (95% CI: 1.05–1.15), and HbA1C test: aOR: 1.11 (95% CI: 1.04–1.18), 1.11 (95% CI: 1.02–1.20), and 1.15 (95% CI: 1.06–1.25) for PCP/NP, PCP/NP/PA, and PCP/PA teams). Patients in the PCP/NP and the PCP/PA teams had a slightly higher likelihood of being prescribed high-risk medications (aOR: 1.03 (95% CI: 1.00–1.07), and 1.06 (95% CI: 1.02–1.11), respectively). The likelihood of preventable hospitalizations was similar among patients cared for by various types of practices.

Conclusion

The team care practices with NPs or PAs were associated with better adherence to clinical practice guideline recommendations for diabetes compared to PCP only practices. Both practices had similar outcomes. Further efforts are needed to explore new and cost-effective team-based care delivery models that improve process, outcomes, and continuity of care, as well as patient care experiences.

Differences in patient population and service provision between nurse practitioner and general practitioner consultations in Swiss primary care: a case study

Background

Primary care systems around the world have implemented nurse practitioners (NPs) to ensure access to high quality care in times of general practitioner (GP) shortages and changing health care needs of a multimorbid, ageing population. In Switzerland, NPs are currently being introduced, and their exact role is yet to be determined. The aim of this study was to get insight into patient characteristics and services provided in NP consultations compared to GP consultations in Swiss primary care.

Methods

This case study used retrospective observational data from electronic medical records of a family practice with one NP and two GPs. Data on patient-provider encounters were collected between August 2017 and December 2018. We used logistic regression to assess associations between the assignment of the patients to the NP or GP and patient characteristics and delivered services respectively.

Results

Data from 5210 patients participating in 27,811 consultations were analyzed. The average patient age was 44.3 years (SD 22.6), 47.1% of the patients were female and 19.4% multimorbid. 1613 (5.8%) consultations were with the NP, and 26,198 (94.2%) with the two GPs. Patients in NP consultations were more often aged 85+ (OR 3.43; 95%-CI 2.70–4.36), multimorbid (OR 1.37; 95%-CI 1.24–1.51; p < 0.001) and polypharmaceutical (OR 1.28; 95%-CI 1.15–1.42; p < 0.001) in comparison to GP consultations. In NP consultations, vital signs (OR 3.05; 95%-CI 2.72–3.42; p < 0.001) and anthropometric data (OR 1.33; 95%-CI 1.09–1.63; p 0.005) were measured more frequently, and lab tests (OR 1.16; 95%-CI 1.04–1.30; p 0.008) were ordered more often compared to GP consultations, independent of patient characteristics. By contrast, medications (OR 0.35; 95%-CI 0.30–0.41; p < 0.001) were prescribed or changed less frequently in NP consultations.

Conclusions

Quantitative data from pilot projects provide valuable insights into NP tasks and activities in Swiss primary care. Our results provide first indications that NPs might have a focus on and could offer care to the growing number of multimorbid, polypharmaceutical elderly in Swiss primary care.

Nurse Practitioner Involvement in Medicare Accountable Care Organizations: Association With Quality of Care

The objective was to examine trend and care quality outcomes associated with nurse practitioner (NP) involvement in Accountable Care Organizations (ACOs) via a cross-sectional study of 521 Medicare Shared Savings Program ACOs during 2014 to 2016. Data include ACO provider/beneficiary files, Medicare claims, and ACO performance data with a focus on Medicare beneficiaries with diabetes, chronic obstructive pulmonary disease, or heart failure. ACO care quality measures were stratified by NP involvement and adjusted for patient, provider, and ACO factors. NP involvement was highest in larger ACOs, states that allow NPs full scope of practice, and rural areas. Greater involvement was associated with fewer readmissions and higher scores on measures of preventive care but not chronic disease and medication management. Greater NP involvement in ACOs was associated with improvement in some care quality measures. With NPs' increasing involvement in ACOs, more research is needed to understand the NP role in processes and outcomes of care.

The Role of Physician and Practice Characteristics in the Quality of Diabetes Management in Primary Care: Systematic Review and Meta-analysis

BACKGROUND

Despite evidence-based guidelines, high-quality diabetes care is not always achieved. Identifying factors associated with the quality of management in primary care may inform service improvements, facilitating the tailoring of quality improvement interventions to practice needs and resources.

METHODS

We searched MEDLINE, EMBASE, CINAHL and Web of Science from January 1990 to March 2019. Eligible studies were cohort studies, cross-sectional studies and randomised controlled trials (baseline data) conducted among adults with diabetes, which examined the relationship between any physician and/or practice factors and any objective measure(s) of quality. Studies which examined patient factors only were ineligible. Where possible, data were pooled using random-effects meta-analysis.

RESULTS

In total, 82 studies were included. The range of individual quality measures and the construction of composite measures varied considerably. Female physicians compared with males ((odds ratio (OR) = 1.07, 95% CI: 1.04, 1.10), 8 studies), physicians with higher diabetes volume compared with lower volume (OR = 1.24, 95% CI: 1.05-1.47, 4 studies) and practices with Electronic Health Records (EHR) versus practices without (OR = 1.43, 95% CI: 1.11-1.84, 4 studies) were associated with a higher quality of care. There was no association between physician experience, practice location and type of practice and quality. Based on the narrative synthesis, increasing physician age and higher practice socio-economic deprivation may be associated with lower quality of care.

DISCUSSION

Identification of physician- and practice-level factors associated with the quality of care (female gender, younger age, physician-level diabetes volume, practice deprivation and EHR use) may explain differences across practices and physicians, provide potential targets for quality improvement interventions and indicate which practices need specific supports to deliver improvements in diabetes care.

Nurse practitioner-physician comanagement of primary care patients: The promise of a new delivery care model to improve quality of care

BACKGROUND

The U.S. primary care system is under tremendous strain to deliver care to an increased volume of patients with a concurrent primary care physician shortage. Nurse practitioner (NP)-physician comanagement of primary care patients has been proposed by some policy makers to help alleviate this strain. To date, no collective evidence demonstrates the effects of NP-physician comanagement in primary care.

PURPOSE

This is the first review to synthesize all available studies that compare the effects of NP-physician comanagement to an individual physician managing primary care.

METHODS

The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) framework guided the conduct of this systematic review. Five electronic databases were searched. Titles, abstracts, and full texts were reviewed, and inclusion/exclusion criteria were applied to narrow search results to eligible studies. Quality appraisal was performed using Downs and Black's quality checklist for randomized and nonrandomized studies.

RESULTS

Six studies were identified for synthesis. Three outcome categories emerged: (a) primary care provider adherence to recommended care guidelines, (b) empirical changes in clinical patient outcomes, and (c) patient/caregiver quality of life. Significantly more recommended care guidelines were completed with NP-physician comanagement. There was variability of clinical patient outcomes with some findings favoring the comanagement model. Limited differences in patient quality of life were found. Across all studies, the NP-physician comanagementcare delivery model was determined to produce no detrimental effect on measured outcomes and, in some cases, was more beneficial in reaching practice and clinical targets.

PRACTICE IMPLICATIONS

The use of NP-physician comanagement of primary care patients is a promising delivery care model to improve the quality of care delivery and alleviate organizational strain given the current demands of increased patient panel sizes and primary care physician shortages. Future research should focus on NP-physician interactions and processes to isolate the attributes of a successful NP-physician comanagement model.

A qualitative study exploring strategies to improve the inter-professional management of diabetes and periodontitis

AIMS

To explore inter-professional communication and collaboration in guideline-concordant diabetes and periodontitis care.

METHODS

Qualitative design using iterations of workshops to identify ways to improve multidisciplinary working attended by staff from medical and dental primary care practices, and people with diabetes (n=43). Workshops were semi-structured around a topic guide. Recruitment was via the UK Clinical Research Network, and a patient and public involvement group in the North of England.

RESULTS

Medical practice participants were unaware of the bidirectional evidence linking diabetes and periodontitis and stated that they had never received a referral from a dental professional in this context. The patient participants with diabetes reported never having been informed about the links between diabetes and periodontitis from either their family physician or dentist. Medical and dental practice participants gave negative accounts of inter-professional communication, with claims of inappropriate requests and defensive or non-responses that stymied future interaction. Indirect communication through the patient was suggested as an alternative to direct communication.

CONCLUSIONS

Indirect referral, whereby the patient is signposted to a healthcare professional, was suggested by medical and dental professionals as a useful alternative to the traditional (and time consuming) letter or telephone call, particularly in the case of suspected diabetes or periodontitis.

Impact of diabetes education teams in primary care on processes of care indicators

AIMS

To evaluate the impact of the integration of onsite diabetes education teams in primary care on processes of care indicators according to practice guidelines.

METHODS

Teams of nurse and dietitian educators delivered individualized self-management education counseling in 11 Ontario primary care sites. Of the 771 adult patients with HbA1c ≥7% who were recruited in a prospective cohort study, 487 patients attended appointments with the education teams, while the remaining 284 patients did not (usual care group). Baseline demographic, clinical information, and patient care processes (diabetes medical visit, HbA1c test, lipid profile, estimated glomerular filtration rate, and albumin-to-creatinine ratio, measuring blood pressure, performing foot exams, provision of flu vaccine, and referral for dilated retinal exam) were collected from patient charts one year before (pre period) and after (post period) the integration began. A multi-level random effects model was used to analyze the effect of group and period on whether the process indicators were met based on practice guidelines.

RESULTS

Compared to the usual care group, patients seen by the education teams had significant improvements on indicators for semi-annual medical visit and annual foot exam. No significant improvements were found for other process of care indicators.

CONCLUSIONS

Onsite education teams in primary care settings can potentially improve diabetes management as shown in two process of care indicators: medical visits and foot exams. The results support the benefits of having education teams in primary care settings to increase adherence to practice guidelines.

Complexity as a factor for task allocation among general practitioners and nurse practitioners: a narrative review

BACKGROUND

General practitioner (GP) shortages and increasing demand for care led to the introduction of nurse practitioners (NPs) to primary care. Many concepts for task sharing among health professionals feature complexity. The aim of this narrative review was to examine how complexity is used as a factor for task allocation between GPs and NPs.

METHODS

According to the PRISMA statement, PubMed and CINAHL were searched systematically, and eligibility criteria were applied to detect literature concerning GPs and NPs in primary care and complexity in the context of task allocation. Relevant information was extracted, and a narrative analysis was performed.

RESULTS

Thirty-seven studies from seven countries were included, comprising quantitative, qualitative, and mixed methods. Complexity was used to describe patients, their needs, and health professionals' tasks. The understanding of the use of complexity as a factor for task allocation between NPs and GPs was based on the patient population (specific vs. unspecific), the setting (specific vs. unspecific), the numbers of health professionals involved (two vs. more than two), and the NP role (distinct model of care vs. no model). Despite similarities in these areas, the tasks which NPs perform range from providing minor to complex care. However, there is a slight trend towards NPs treating socially complex patients and GPs focusing on medically complex cases.

CONCLUSION

Complexity as a concept is prominent in primary care but remains broad and inconsistent as a factor for task allocation between NPs and GPs. This review can be used as a point of reference when practitioners are seeking methods for task allocation in a collaborative primary care setting.

Outcomes of primary care delivery by nurse practitioners: Utilization, cost, and quality of care

OBJECTIVE

To examine whether nurse practitioner (NP)-assigned patients exhibited differences in utilization, costs, and clinical outcomes compared to medical doctor (MD)-assigned patients.

DATA SOURCES

Veterans Affairs (VA) administrative data capturing characteristics, outcomes, and provider assignments of 806 434 VA patients assigned to an MD primary care provider (PCP) who left VA practice between 2010 and 2012.

STUDY DESIGN

We applied a difference-in-difference approach comparing outcomes between patients reassigned to MD and NP PCPs, respectively. We examined measures of outpatient (primary care, specialty care, and mental health) and inpatient (total and ambulatory care sensitive hospitalizations) utilization, costs (outpatient, inpatient and total), and clinical outcomes (control of hemoglobin A1c, LDL, and blood pressure) in the year following reassignment.

PRINCIPAL FINDINGS

Compared to MD-assigned patients, NP-assigned patients were less likely to use primary care and specialty care services and incurred fewer total and ambulatory care sensitive hospitalizations. Differences in costs, clinical outcomes, and receipt of diagnostic tests between groups were not statistically significant.

CONCLUSIONS

Patients reassigned to NPs experienced similar outcomes and incurred less utilization at comparable cost relative to MD patients. NPs may offer a cost-effective approach to addressing anticipated shortages of primary care physicians.

From education to practice: What we can learn about the workforce from a survey of new nurse practitioners

BACKGROUND AND PURPOSE

To understand the posttraining plans and job market for new nurse practitioners (NPs), a survey was conducted of new family NPs (FNPs) in 2017. The survey was also designed to test the logistics and feasibility of conducting such a survey on a national scale and the usefulness of data gathered.

METHODS

A descriptive, cross-sectional study was conducted through an online survey administered to a national sample of 159 FNPs who graduated from an accredited NP program.

CONCLUSIONS

Many new NPs are not willing or interested in moving out of their local community even if there are limited opportunities locally. There are high numbers of NPs going into private practice compared with community health or federally qualified health centers. Many new NPs have extensive previous work experience as registered nurses in hospitals; the career progression to NP shifts their work setting from inpatient to outpatient settings.

IMPLICATIONS FOR PRACTICE

Although the job market for new NPs is generally good, with the rapid increase in NP graduates combined with the unwillingness or inability of many new NPs to move, some areas may have surpluses of NPs and limited job opportunities for new NPs, whereas other areas may have shortages upcoming. The survey of new NP graduates is a useful tool to monitor the experience of new NPs and provides valuable information to NP programs and prospective students. Future research should ensure a representative sample of new graduate NPs to accurately reflect the experience of new NPs.

Pathways to Independent Primary Care Clinical Practice: How Tall Is the Shortest Giant?

Patients can be treated by a physician, a nurse practitioner (NP), or a physician assistant (PA) despite marked differences in the education and training for these three professions. This natural experiment allows examination of a critical question: What is the minimum education and training required to practice primary care? In other words, how tall is the shortest giant? State licensing requirements, not educational bodies, legislate minimum training. The current minimum is 6 years, which includes 27.5 weeks of supervised clinical experience (SCE), for NPs. In comparison, PAs train for 6 years with 45 weeks of SCE, and physicians for at least 8 years with 110 weeks of SCE. Initial, flawed studies show equivalent patient outcomes among the professions. If rigorous follow-up studies confirm equivalence, the content and length of medical education for primary care physicians should be reconsidered. Unmatched medical school graduates, with 7 years of training and 65 weeks of SCE, more than the required minimum for NPs, deserve to practice independently. So do PAs. If equivalence is not confirmed, the minimum requirements for NPs and/or PAs should be raised, including considering a required residency (currently optional). Alternatively, the scope of practice for the three professions could be defined to reflect differences in training. There is an urgent need to set aside preconceived notions and turf battles, conduct rigorous independent studies, and generate meaningful data on practice patterns and patient outcomes. This should inform optimal training, scope of practice, and workforce development for each invaluable primary care clinical practitioner.

Exploring Clinical Care Among Adults With Diabetes Mellitus: Alignment With Recommended Statin and Sulfonylureas Treatment

OBJECTIVES

The care of patients with diabetes mellitus (DM), compiled in the 2008 Canadian Diabetes Association clinical practice guidelines and in recommendations from the Choosing Wisely Canada program, is informed by a large body of evidence. This study sought to assess to what extent primary care providers (PCPs) incorporate recommended statin and sulfonylureas treatment in their care of patients with DM, and to identify the association between use of recommended care and PCP characteristics.

METHODS

This retrospective cohort study (2007-2017) used electronic medical records of 21,149 patients with DM receiving care from 240 PCPs participating in the Manitoba Primary Care Research Network.

RESULTS

PCPs prescribed statins to patients newly diagnosed with DM who were ≥40 years of age 41% of the time, with 45% of the prescriptions occurring ≤180 days after a new diagnosis (early treatment). PCPs least likely to prescribe recommended statin treatment had higher odds of being older (adjusted odds ratio [aOR], 1.05; 95% confidence interval [CI], 1.01 to 1.09) and fee-for-service funded (aOR, 4.36; 95% CI, 1.47 to 12.91). In addition, older PCPs (aOR, 1.06; 95% CI, 1.02 to 1.10) and women (aOR, 2.42; 95% CI, 1.11 to 5.28) were less likely to prescribe statin treatment early. Seventy-four percent of PCPs prescribed sulfonylureas to adults ≥65 years of age. No PCP characteristics were associated with prescription of sulfonylureas in the lower implementation quartile in the fully adjusted model.

CONCLUSIONS

Results suggest that PCPs' practice does not always align with current evidence-based clinical guidelines or Choosing Wisely Canada recommendations for patients with DM. Some PCP's characteristics were associated with lower implementation of recommended evidence-based care. This information can help guide future targeted medical education.

Nurse Practitioner Practice Environments in Primary Care and Quality of Care for Chronic Diseases

BACKGROUND

The chronic disease burden in the United States represents a significant challenge for the primary care system. The nurse practitioner (NP) workforce can help meet the demand for care; however, organizational barriers such as poor practice environments prevent NPs from delivering high quality care.

OBJECTIVES

We investigated the relationship between NP practice environments and quality of care for chronic diseases.

RESEARCH DESIGN

We fit regression models to assess cross-sectional associations between claims-based quality measure performance and survey data on NP practice environments in Massachusetts.

SUBJECTS

We used survey data from 221 primary care NPs from 118 practices. We obtained quality of care data for patients with asthma, diabetes, and cardiovascular disease.

MEASURES

The Nurse Practitioner Primary Care Organizational Climate Questionnaire was used to measure practice environments with its following 4 subscales: NP-Physician Relations, Independent Practice and Support, Professional Visibility, and NP-Administration Relations. Three Healthcare Effectiveness Data and Information Set measures were used to evaluate the quality of care.

RESULTS

A 1-SD increase in the organizational-level NP-Administration Relations subscale score was associated with a near doubling of the odds of receiving medication management for asthma. A 1-SD increase in the organizational-level Independent Practice and Support subscale score was associated with a 60% increase in the odds of receiving recommended screening for cardiovascular disease. There was no impact on diabetes care measure.

CONCLUSIONS

NP practice environment affected the quality of care for 2 chronic conditions. Efforts should be implemented to improve NP practice environment to potentially improve care quality.

Interprofessional collaboration in diabetes care: perceptions of family physicians practicing in or not in a primary health care team

BACKGROUND

In Canada, most patients with type 2 diabetes mellitus (T2DM) are cared for in the primary care setting in the practices of family physicians. This care is delivered through a variety of practice models ranging from a single practitioner to interprofessional team models of care. This study examined the extent to which family physicians collaborate with other health professionals in the care of patients with T2DM, comparing those who are part of an interprofessional health care team called a Primary Care Network (PCN) to those who are not part of a PCN.

METHODS

Family physicians in Alberta, Canada were surveyed to ascertain: which health professionals they refer to or have collaborative arrangements with when caring for T2DM patients; satisfaction and confidence with other professionals' involvement in diabetes care; and perceived effects of having other professionals involved in diabetes care. Chi-squared and Fishers Exact tests were used to test for differences between PCN and non-PCN physicians.

RESULTS

170 (34%) family physicians responded to the survey, of whom 127 were PCN physicians and 41 were non-PCN physicians (2 not recorded). A significantly greater proportion of PCN physicians vs non-PCN physicians referred patients to pharmacists (23.6% vs 2.6%) or had collaborative working arrangements with diabetes educators (55.3% vs 18.4%), dietitians (54.5% vs 21.1%), or pharmacists (43.1% vs 21.1%), respectively. Regardless of PCN status, family physicians expressed greater satisfaction and confidence in specialists than in other family physicians or health professionals in medication management of patients with T2DM. Physicians who were affiliated with a PCN perceived that interprofessional collaboration enabled them to delegate diabetes education and monitoring and/or adjustment of medications to other health professionals and resulted in improved patient care.

CONCLUSIONS

This study sheds new insight on the influence that being part of a primary care team has on physicians' practice. Specifically, supporting physicians' access to other health professionals in the primary care setting is perceived to facilitate interprofessional collaboration in the care of patients with T2DM and improve patient care.

Uncovering the wisdom hidden between the lines: the Collaborative Reflexive Deliberative Approach

BACKGROUND

Meta-analysis and meta-synthesis have been developed to synthesize results across published studies; however, they are still largely grounded in what is already published, missing the tacit 'between the lines' knowledge generated during many research projects that are not intrinsic to the main objectives of studies.

OBJECTIVE

To develop a novel approach to expand and deepen meta-syntheses using researchers' experience, tacit knowledge and relevant unpublished materials.

METHODS

We established new collaborations among primary health care researchers from different contexts based on common interests in reforming primary care service delivery and a diversity of perspectives. Over 2 years, the team met face-to-face and via tele- and video-conferences to employ the Collaborative Reflexive Deliberative Approach (CRDA) to discuss and reflect on published and unpublished results from participants' studies to identify new patterns and insights.

RESULTS

CRDA focuses on uncovering critical insights, interpretations hidden within multiple research contexts. For the process to work, careful attention must be paid to ensure sufficient diversity among participants while also having people who are able to collaborate effectively. Ensuring there are enough studies for contextual variation also matters. It is necessary to balance rigorous facilitation techniques with the creation of safe space for diverse contributions.

CONCLUSIONS

The CRDA requires large commitments of investigator time, the expense of convening facilitated retreats, considerable coordination, and strong leadership. The process creates an environment where interactions among diverse participants can illuminate hidden information within the contexts of studies, effectively enhancing theory development and generating new research questions and strategies.

Nurse Practitioners, Physician Assistants, and Physicians Are Comparable in Managing the First Five Years of Diabetes

BACKGROUND

Increasing use of nurse practitioners and physician assistants is a possible solution to the shortage of primary care providers in the United States, but the quality of care they provide is not well understood.

METHODS

Because the scope of practice of the 3 provider types is similar in the Veterans Health Administration, we determined whether patients managed by primary care nurse practitioners, physician assistants, or physicians had similar hemoglobin A1c levels at comparable times in the natural history of diabetes. Our retrospective cohort study examined veterans with newly diagnosed diabetes in 2008, continuous primary care from 2008 to 2012, and more than 75% of primary care visits with nurse practitioner, physician assistant, or physician.

RESULTS

Of the 19,238 patients, 95.3% were male, 77.7% were white, and they had a mean age 68.5 years; 14.7%, 7.1%, and 78.2% of patients were managed by nurse practitioners, physician assistants, and physicians, respectively. Median hemoglobin A1c was comparable at diagnosis (6.6%, 6.7%, 6.7%, P > .05) and after 4 years (all 6.5%, P > .5). Hemoglobin A1c levels at initiation of the first (7.5%-7.6%) and second (8.0%-8.2%) oral medications for patients of nurse practitioners and physician assistants compared with that of physicians was also similar after adjusting for patient characteristics (all P > .05). Nurse practitioners started insulin at a lower hemoglobin A1c (9.4%) than physicians (9.7%), which remained significant after adjustment (P < .05).

CONCLUSIONS

At diagnosis and during 4 years of follow-up, diabetes management by nurse practitioners and physician assistants was comparable to management by physicians. The Veterans Health Administration model for roles of nurse practitioners and physician assistants may be broadly useful to help meet the demand for primary care providers in the United States.

Availability of primary care team members can improve teamwork and readiness for change

BACKGROUND

Early experiences of patient-centered medical home implementation indicate that redesigning primary care is an intensive organizational change that is most effectively undertaken by high-functioning interdisciplinary teams. Team effectiveness research indicates that consistent availability of team members and other aspects of team structure can impact teamwork and organizational outcomes.

METHODS

We conducted a survey of 766 adult primary care providers and staff in 34 California safety net practices to assess primary care team structure (team size, team member availability, and access to interdisciplinary expertise), teamwork, and readiness for change. We used path models with robust standard errors for clustering of respondents within practices to examine relationships between team member availability and readiness for change. Using path analysis, we examined the extent to which better teamwork mediated relationships between team member availability and readiness for change.

RESULTS

We received 628 completed surveys (response rate = 82%). Greater team member availability was associated with greater readiness for change, but the relationship was stronger for staff than for primary care providers. Contrary to our hypothesis, path analyses revealed that the relationship of team member availability and greater readiness for change was only partially mediated (21%) by better teamwork. The direct effect of teamwork on readiness for change is approximately 2.9 times larger than the direct effect of team member availability on greater readiness for change.

CONCLUSIONS

Ensuring that members perceive that their teammates are routinely available to them may improve readiness for implementing organizational changes like adopting patient-centered medical home models. Given that better teamwork only partially explained the availability-readiness relationship, additional research to identify the mechanisms through which consistent team member availability increases change readiness could lend insight into how to more effectively support clinicians and staff undergoing complex organizational changes.

When peers count: The effects on integrated type II diabetes care of communication within general practitioner-only subgroups in interprofessional primary care teams

BACKGROUND

Primary care teams (hereafter referred to as primary care units [PCUs]) composed of general practitioners (GPs), nurses, and specialist doctors have recently been established in the Italian context, with the main aim of improving integrated care for chronic diseases.

PURPOSES

The aim of the study was to assess whether the increased professional diversity of PCUs has resulted in an improvement in the integrated care of type II diabetes and to identify a potential mechanism mediating this effect.

METHODOLOGY/APPROACH

We analyzed 213 PCUs, comparing their performance in integrated type II diabetes care at two time points. Using social categorization theory and a fixed effects regression analysis, we tested a mediation model in which the frequency of communication among GPs in the PCUs, that is, within-subgroup communication, mediates the relationship between PCU professional diversity and team performance in diabetes care.

FINDINGS

We show that when the professional diversity of the PCUs increases, integrated care of type II diabetes improves and better meets the standards of optimal care. Within-GP subgroup communication works as a mediating mechanism that translates the PCU professional diversity into better team performance. The mediation effect, however, is curvilinear. Beyond certain levels, within-subgroup communication can hamper PCUs' capacity to work collaboratively in integrated type II diabetes care.

PRACTICE IMPLICATIONS

The article suggests that, when creating interprofessional primary care teams, managers might be able to steer teams toward a better performance by encouraging communication among peers of the same profession.

Redesigning Diabetes Care: Defining the Role of Endocrinologists Among Alternative Providers

The current diabetes epidemic threatens to overwhelm the healthcare system unless we redesign how diabetes care is delivered. The number of endocrinologists is grossly inadequate to provide care for all individuals with diabetes, but with the appropriate utilization of the primary care workforce and alternative healthcare providers working together in teams, effective diabetes care can be provided to all. We propose a patient-centered, goal-based approach with resources devoted to care coordination, measurement of outcomes, appropriate use of technology, and measurement of patient satisfaction. Financial incentives to healthcare systems and providers need to be based on defined outcome measures and reducing long-term total medical expenditures, rather than reimbursement based on number of visits and lengthy documentation. Endocrinologists have a responsibility in setting up effective diabetes care delivery systems within their organizations, in addition to delivering diabetes care and serving as a resource for the educational needs for other medical professionals in the community. There are major challenges to implementing such systems, both at the financial and organizational levels. We suggest a stepwise implementation of discrete components based on the local priorities and resources and provide some examples of steps we have taken at our institution.

Cholesterol testing among men and women with disability: the role of morbidity

PURPOSE

Despite more frequent use of health services by people living with disability, the quality of preventive care received may be suboptimal. In this retrospective cohort study, we used administrative data to examine the relationship between cholesterol testing and levels of disability and morbidity among women and men in Ontario, Canada.

METHODS

We linked multiple provincial-level databases in this study. In stratified analyses for women and men, we used multivariable logistic regression to examine differences in cholesterol testing, and we tested for an interaction effect between disability and morbidity. In a secondary analysis, we tested for a three-way interaction between sex, disability, and morbidity on the entire cohort.

RESULTS

There was an interaction between morbidity and disability for both women and men. Women and men with no chronic conditions appeared to be least likely to be up-to-date on cholesterol testing, and among this group, those with moderate disability were more likely to be up-to-date on cholesterol testing than those with no disability (adjusted odds ratio [AOR] =1.51; 95% confidence interval [CI] 1.20-1.90 for women; AOR =1.16; 95% CI 1.00-1.34 for men). Among women and men who had one chronic condition, having severe disability put them at significant disadvantage versus those with no disability. Only 58.5% of men with no disability and no chronic conditions were up-to-date on cholesterol testing.

CONCLUSION

An intermediate level of health care need (reflected in this study as level of disability and level of morbidity) may provide a benefit for cholesterol testing, and conversely, health care needs that are too few or too great may negatively affect testing. Public health and practice-based interventions need to be explored to address these findings.

Primary care physician assistant and advance practice nurses roles: Patient healthcare utilization, unmet need, and satisfaction

PURPOSE

Team-based care involving physician assistants (PAs) and advance practice nurses (APNs) is one strategy for improving access and quality of care. PA/APNs perform a variety of roles on primary care teams. However, limited research describes the relationship between PA/APN role and patient outcomes. We examined multiple outcomes associated with primary care PA/APN roles.

METHODS

In this cross-sectional survey analysis, we studied adult respondents to the 2010 Health Tracking Household Survey. Outcomes included primary care and emergency department visits, hospitalizations, unmet need, and satisfaction. PA/APN role was categorized as physician only (no PA/APN visits; reference), usual provider (PA/APN provide majority of primary care visits) or supplemental provider (physician as usual provider, PA/APN provide a subset of visits). Multivariable logistic and multinomial logistic regressions were performed.

RESULTS

Compared to people with physician only care, patients with PA/APNs as usual providers [5-9 visits RRR=2.4 (CI 1.8-3.4), 10+ visits RRR=3.0 (CI 2.0-4.5): reference 2-4 visits] and supplemental providers had increased risk of having 5 or more primary care visits [5-9 visits RRR=1.3 (CI 1.0-1.6)]. Patients reporting PA/APN as supplemental providers had increased risk of emergency department utilization [2+ visits: RRR 1.8 (CI 1.3, 2.5)], and lower satisfaction [very dissatisfied: RRR 1.8 (CI 1.03-3.0)]. No differences were seen for hospitalizations or unmet need.

CONCLUSIONS

Healthcare utilization patterns and satisfaction varied between adults with PA/APN in different roles, but reported unmet need did not. These findings suggest a wide range of outcomes should be considered when identifying the best PA/APN role on primary care teams.

The impact of Multimedia Software Support on the Knowledge and Self-Care Behaviors of Patients with Type 2 Diabetes: a Randomized Clinical Trial

Introduction: Education is the most effective and economical part of diabetes treatment. The purpose of this study was to investigate the effect of a training program with multimedia software on the knowledge and self-care behaviors of patients with type 2 diabetes.

Methods: This study was a randomized controlled clinical trial in which 60 patients referred to diabetes clinic at Arak city were divided randomly into experimental (n=30) and control (n=30) groups. The instruments for collecting data were "Summary of Diabetes self-care activities questionnaire" and "knowledge of self-care in patients with diabetes". Data were collected before and 2 months after the intervention in the both groups. Educational program with equal content was applied for both experimental group (self-care program with multimedia software support) & control group (lecture and presentation with PowerPoint). Data analysis was done using SPSS Ver.13.

Results: Implementation of the self-care program with multimedia software support resulted in improvements in patients’ self-care behaviors in the experimental group, whereas these behaviors had not significant changes in the control group after eight weeks. There was a significant difference in the mean score of knowledge in both the experiment and control groups before and after the intervention.

Conclusion: Considering beneficial effects of training program with multimedia software support on the knowledge and self-care behaviors and the importance of this issue, suggested that the patients preferably provide terms of use of educational software for themselves.

Comparison of Care Provided in Practices With Nurse Practitioners and Physician Assistants Versus Subspecialist Physicians Only: A Cohort Study of Rheumatoid Arthritis

OBJECTIVE

The Affordable Care Act proposes wider use of nurse practitioners (NPs) and physician assistants (PAs), but little is known about outcomes of care provided by them in medical specialties. We compared the outcomes of care for patients with rheumatoid arthritis (RA) seen in practices with NPs or PAs and rheumatologists versus practices with rheumatologists only.

METHODS

We enrolled 7 rheumatology practices in the US (4 with NPs or PAs and 3 without). RA disease activity (categorized as in remission, low, moderate, or high, using standardized measures) was abstracted from medical records from the most recent 2 years. We performed a repeated-measures analysis using generalized linear regression to compare disease activity for visits to practices with NPs or PAs versus rheumatologist-only practices, adjusting for disease duration, serologic status, RA treatments, and disease activity measures.

RESULTS

Records from 301 patients, representing 1,982 visits, were reviewed. The patients' mean age was 61 years and 77% were female. In the primary adjusted analysis, patients seen in practices with NPs or PAs were less likely to have higher disease activity (odds ratio 0.32, 95% confidence interval 0.17-0.60; P = 0.004) than those seen in rheumatologist-only practices. However, there were no differences in the change in disease activity.

CONCLUSION

Patients seen in practices with NPs or PAs had lower RA disease activity over 2 years compared to those seen in rheumatologist-only practices; no differences were observed in the change in disease activity between visits either within or between the different types of provider practice.

Level of control among patients with type 2 diabetes mellitus attending diabetic clinic under family medicine compared to diabetic clinic under endocrinology

OBJECTIVES

To assess and compare level of control among patients with type 2 diabetes mellitus attending diabetic clinic under family medicine service and patients attending diabetic clinics under endocrinology service, and to explore the effect of different variables on the level of control in both groups.

METHODS

Retrospective cross-sectional study by reviewing medical records of patients with type 2 diabetes mellitus and laboratory studies from Hospital Information System at King Abdul-Aziz Medical City, National Guard, Riyadh - Saudi Arabia using predesigned sheet for data collection.

RESULTS

Among 352 patients enrolled in the study, 176 (50%) patients were from the family medicine setting and 176 (50%) patients were from the hospital setting. The mean glycosylated hemoglobin for the whole study population was 8.97±1.87. There was no significant difference between the two groups in regard to level of control (9.01±1.75 in the family medicine setting compared to 8.93±1.98 in the hospital setting). No significant correlation was found between level of control and age, duration of disease and number of follow-up visits in both settings.

CONCLUSION

Patients with type 2 diabetes mellitus in this study were found to be poorly controlled in both the settings, diabetic clinic under family medicine and diabetic clinic under endocrinology. More research should be done to explore quality of care in a family medicine setting for patients with type 2 diabetes mellitus, as such a setting is expected to be more accessible, more convenient, and more cost effective to patients.

Nurse practitioner perceptions of the impact of physician oversight on quality and safety of nurse practitioner practice

PURPOSE

Nurse practitioner (NP) regulation and physician oversight (PO) of NP practice are inextricably intertwined. A flexible, well-prepared workforce is needed to meet consumer healthcare needs. All outcome studies have revealed that NPs provide safe, effective, quality care with outcomes equal to or better than that of physicians or physician assistants. Variability in state regulation of NP practice limits the full deployment of these proven healthcare providers, threatens the quality and safety of NP-delivered care, and limits consumer choice in healthcare access. The purpose of this study was to document NP perceptions of the impact of PO on the safety and quality of NP practice.

DATA SOURCES

A total of 1139 NP respondents completed an exploratory survey, Impact of Regulatory Requirements for Physician Oversight on Nurse Practitioner Practice. Participants were asked their perceptions of the impact of PO on patient care and NP practice. Descriptive statistics on the state of residence regulatory requirements and personal demographics were also collected.

CONCLUSIONS

NP perceptions of the impact of PO on the safety and quality of NP practice were predicted by NP experience and state regulatory environment ranking.

IMPLICATIONS FOR PRACTICE

The results of this study have implications for educators, policy makers, and nursing advocacy groups seeking to increase access to care in U.S.

POPULATIONS

Study participants perceived that requirements for PO impacted their practice and may jeopardize patient safety. An understanding of the impact of influences on regulatory processes is critical to ensuring full deployment of NPs as interprofessional leaders to meet current and future healthcare access.

Comparing the Cost of Care Provided to Medicare Beneficiaries Assigned to Primary Care Nurse Practitioners and Physicians

OBJECTIVE

This study is designed to assess the cost of services provided to Medicare beneficiaries by nurse practitioners (NPs) billing under their own National Provider Identification number as compared to primary care physicians (PCMDs).

DATA SOURCE

Medicare Part A (inpatient) and Part B (office visit) claims for 2009-2010.

STUDY DESIGN

Retrospective cohort design using propensity score weighted regression.

DATA EXTRACTION METHODS

Beneficiaries cared for by a random sample of NPs and primary care physicians.

PRINCIPAL FINDINGS

After adjusting for demographic characteristics, geography, comorbidities, and the propensity to see an NP, Medicare evaluation and management payments for beneficiaries assigned to an NP were $207, or 29 percent, less than PCMD assigned beneficiaries. The same pattern was observed for inpatient and total office visit paid amounts, with 11 and 18 percent less for NP assigned beneficiaries, respectively. Results are similar for the work component of relative value units as well.

CONCLUSIONS

This study provides new evidence of the lower cost of care for beneficiaries managed by NPs, as compared to those managed by PCMDs across inpatient and office-based settings. Results suggest that increasing access to NP primary care will not increase costs for the Medicare program and may be cost saving.

Optimizing full scope of practice for nurse practitioners in primary care: A proposed conceptual model

BACKGROUND

Nurse practitioners (NPs), if utilized to their optimal potential, could play a key role in meeting the growing demand for primary care.

PURPOSE

The purpose of this study was to propose a comprehensive model for maximizing NP contributions to primary care which includes the factors affecting NP care and patient outcomes and explains their interrelated impact.

METHOD

We synthesized the results of the published literature to develop a model, which emphasizes NP scope of practice regulations, institutional policies, NP practice environment, and NP workforce outcomes as determinants of NP care and patient outcomes.

DISCUSSION

Our model provides a framework to help explain how variations in scope of practice regulations at the state-level and institutional policies within organizations directly and indirectly influence the practice environment of NPs, NP workforce outcomes, and patient care and outcomes.

CONCLUSION

Aligning policy change, organizational innovations, and future research are critical to NP optimal utilization and patient care and outcomes.

Influence of provider mix and regulation on primary care services supplied to US patients

Access to medical care and how it differs for various patients remain key policy issues. While existing work has examined clinic structure's influence on productivity, less research has explored the link between provider mix and access for different patient types - which also correspond to different service prices. We exploit experimental data from a large field study spanning 10 US states where trained audit callers were randomly assigned an insurance status and then contacted primary care physician practices seeking new patient appointments. We find clinics with more non-physician clinicians are associated with better access for Medicaid patients and lower prices for office visits; however, these relationships are only found in states granting full practice autonomy to these providers. Substituting more non-physician labor in primary care settings may facilitate greater appointment availability for Medicaid patients, but this likely rests on a favorable policy environment. Relaxing regulations for non-physicians may be an important initiative as US health reforms continue and also relevant to other countries coping with greater demands for medical care and related financial strain.

Diabetes Mellitus Care Provided by Nurse Practitioners vs Primary Care Physicians

OBJECTIVES

To compare processes and cost of care of older adults with diabetes mellitus cared for by nurse practitioners (NPs) with processes and cost of those cared for by primary care physicians (PCPs).

DESIGN

Retrospective cohort study.

SETTING

Primary care in communities.

PARTICIPANTS

Individuals with a diagnosis of diabetes mellitus in 2009 who received all their primary care from NPs or PCPs were selected from a national sample of Medicare beneficiaries (N = 64,354).

MEASUREMENTS

Propensity score matching within each state was used to compare these two cohorts with regard to rate of eye examinations, low-density lipoprotein cholesterol (LDL-C) and glycosylated hemoglobin (HbA1C) testing, nephropathy monitoring, specialist consultation, and Medicare costs. The two groups were also compared regarding medication adherence and use of statins, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (for individuals with a diagnosis of hypertension), and potentially inappropriate medications (PIMs).

RESULTS

Nurse practitioners and PCPs had similar rates of LDL-C testing (odds ratio (OR) = 1.01, 95% confidence interval (CI) = 0.94-1.09) and nephropathy monitoring (OR = 1.05, 95% CI = 0.98-1.03), but NPs had lower rates of eye examinations (OR = 0.89, 95% CI = 0.84-0.93) and HbA1C testing (OR = 0.88, 95% CI = 0.79-0.98). NPs were more likely to have consulted cardiologists (OR = 1.29, 95% CI = 1.21-1.37), endocrinologists (OR = 1.64, 95% CI = 1.48-1.82), and nephrologists (OR = 1.90, 95% CI = 1.67-2.17) and more likely to have prescribed PIMs (OR = 1.07, 95% CI = 1.01-1.12). There was no statistically significant difference in adjusted Medicare spending between the two groups (P = .56).

CONCLUSION

Nurse practitioners were similar to PCPs or slightly lower in their rates of diabetes mellitus guideline-concordant care. NPs used specialist consultations more often but had similar overall costs of care to PCPs.

Standard compared with mnemonic counseling for fecal incontinence: a randomized controlled trial

OBJECTIVE

To estimate whether women who underwent mnemonic counseling had better recall of fecal incontinence therapies at 2 months and if mnemonic counseling resulted in greater satisfaction with physician counseling and improvement in quality of life when compared with a group who underwent standard counseling.

METHODS

Counseling-naive women with fecal incontinence were recruited from an academic urogynecology clinic. Women underwent physical examinations, completed the Quality of the Physician-Patient Interaction, recorded fecal incontinence treatment options they recalled, and completed the Fecal Incontinence Severity Index and Manchester Health Questionnaire immediately after counseling and again at 2 months.

RESULTS

Ninety women consented to participate, were randomized, and completed baseline questionnaires. At baseline, women did not differ in age, ethnicity, education, Fecal Incontinence Severity Index, or Manchester Health Questionnaire scores. After counseling, the mnemonic group reported higher satisfaction on Quality of the Physician-Patient Interaction (66.4±6.5 compared with 62.2±10.7, P=.03). Ninety percent (81/90) of women followed up at 2 months. Our primary endpoint, 2-month recall of fecal incontinence treatments, was not different between groups (2.3±1.6 mnemonic counseling compared with 1.8±1.0 standard counseling; P=.08). Secondary endpoints for the mnemonic group reported greater improvement on total Manchester Health Questionnaire (P=.02), emotional (P=.03), sleep (0.045), role limitations (P<.01), and physical limitations (P=.04) when compared with the standard group.

CONCLUSION

Fecal incontinence counseling with a mnemonic aid did not improve recall at 2 months but improved patient satisfaction and quality of life at 2 months.

Nurse practitioners, physician assistants, and physicians in community health centers, 2006-2010

PURPOSE

Community health centers (CHCs) fill a vital role in providing health care to underserved populations. This project compares characteristics of patient visits to nurse practitioners (NPs), physician assistants (PAs), and physicians in CHCs.

METHODS

This study analyzes 2006-2010 annual survey data from the National Ambulatory Medical Care Survey CHC sample, a representative national sample of CHC providers and patient visits. We examine trends in provider mix in CHCs and compare NPs, PAs, and physicians with regard to patient and visit attributes. Survey weights are used to produce national estimates.

RESULTS

There were, on average, 36,469,000 patient visits per year to 150,100 providers at CHCs; 69% of visits were to physicians, 21% were to NPs, and 10% were to PAs. Compared to visits to NPs, visits made to physicians and PAs tended to be for chronic disease treatment and for patients whom they serve as primary care providers. Visits to NPs tended to be for preventive care.

CONCLUSIONS

This study found more similarities than differences in characteristics of patients and patient visits to physicians, NPs, and PAs in CHCs. When statistical differences were observed, NP patient and visit characteristics tended to be different from those of physicians.

IMPLICATIONS

Results provide detailed information about visits to NPs and PAs in a setting where they constitute a significant portion of providers and care for vulnerable populations. Results can inform future workforce approaches.

Impact of provider type on hepatitis C outcomes with boceprevir-based and telaprevir-based regimens

GOALS

To examine the effect of provider type on outcomes and safety in a large hepatitis C virus (HCV)-infected cohort treated in routine medical practice.

BACKGROUND

Nonphysician providers (NPP) are uniquely positioned to expand health care infrastructure to meet HCV treatment demands.

STUDY

Retrospective, observational cohort analysis of 820 HCV genotype 1-infected veterans initiated on peginterferon/ribavirin and boceprevir or telaprevir in routine medical practice at 94 VA facilities before January 1, 2012 and followed through July 30, 2013. Provider type was determined from prescription records and included physicians (MD) or NPPs (ie, nurse practitioners, physician assistants, and pharmacists). Inverse probability-of-treatment weighting and unweighted logistic regression analysis was used for comparison of sustained virologic response (SVR), treatment discontinuation rates, and adverse hematologic events.

RESULTS

There was no significant difference in SVR by provider type overall (NPPs 52% vs. MDs 49%, P=0.33) and within patient subgroups, or in treatment discontinuation rates. In multivariate analyses, provider type was not associated with any significant difference in the odds of achieving SVR (NPP vs. MD; odds ratio 1.17; 95% confidence interval, 0.84-1.63; P=0.37 inverse probability of treatment weighting; odds ration 1.16, 95% confidence interval, 0.84-1.59, P=0.38 unweighted). Hematologic adverse event rates were similar: anemia: 57% NPP, 62% MD; thrombocytopenia: 43% NPP, 40% MD; neutropenia: 40% NPP, 39% MD.

CONCLUSIONS

Treatment prescribed by NPPs was as likely to result in SVR as treatment prescribed by MDs, even after accounting for patient differences. Engaging more NPPs as HCV treatment providers may allow wider access to HCV treatment.

Quality of diabetes care in family medicine practices in eastern Bosnia and Herzegovina

OBJECTIVES

In the present study, the audit of medical files of patients with diabetes, followed in family medicine practices in the eastern region of Bosnia and Herzegovina (BiH), was carried out in order to investigate the frequency of the use of screening tests for early diagnosis of diabetes complications.

METHODS

The audit was conducted in 32 family medicine practices from 12 primary health care centers in the eastern part of BiH over one-year period (March 2010 to March 2011). A specially established audit team randomly selected medical files of 20 patients with diabetes from the Diabetes Registry administered by each family medicine team database. Screening tests assessed are selected according to the ADA guidelines.

RESULTS

Frequency of the individual screening test varied between 99%, found for at least one blood pressure measurement, and 3.8% for ABI measurement. When the frequency of optimal use of screening was analyzed, only 1% of patients received all recommended screening tests.

CONCLUSION

The frequency of the use of screening tests for chronic diabetes complications was found to be low in the eastern part of Bosnia and Herzegovina. Multivariate linear regression analysis showed that longer duration of diabetes and a larger number of diabetics per practice were associated with a smaller number of screening tests, but specialists in family medicine provided a higher number of screening tests compared to other physicians.

Physician assistants and nurse practitioners perform effective roles on teams caring for Medicare patients with diabetes

One approach to the patient-centered medical home, particularly for patients with chronic illnesses, is to include physician assistants (PAs) and nurse practitioners (NPs) on primary care teams. Using Medicare claims and electronic health record data from a large physician group, we compared outcomes for two groups of adult Medicare patients with diabetes whose conditions were at various levels of complexity: those whose care teams included PAs or NPs in various roles, and those who received care from physicians only. Outcomes were generally equivalent in thirteen comparisons. In four comparisons, outcomes were superior for the patients receiving care from PAs or NPs, but in three other comparisons the outcomes were superior for patients receiving care from physicians only. Specific roles performed by PAs and NPs were associated with different patterns in the measure of the quality of diabetes care and use of health care services. No role was best for all outcomes. Our findings suggest that patient characteristics, as well as patients' and organizations' goals, should be considered when determining when and how to deploy PAs and NPs on primary care teams. Accordingly, training and policy should continue to support role flexibility for these health professionals.

Roles of nurse practitioners and physician assistants in rheumatology practices in the US

OBJECTIVE

A recent workforce study of rheumatology in the US suggests that during the next several decades, the demand for rheumatology services will outstrip the supply of rheumatologists. Midlevel providers such as nurse practitioners and physician assistants may be able to alleviate projected shortages.

METHODS

We administered a nationwide survey of midlevel providers during 2012. Invitations with the survey were sent with one followup reminder. The survey contained questions regarding demographics, training, level of practice independence, responsibilities, drug prescribing, use of objective outcome measures, and knowledge and use of treat-to-target (TTT) strategies.

RESULTS

The invitation was sent to 482 eligible midlevel providers via e-mail and 90 via US mail. We received a total of 174 responses (30%). The mean age was 46 years and 83% were women. Nearly 75% had ≤10 years of experience and 53% had received formal training in rheumatology. Almost two-thirds reported having their own panel of patients. The top 3 practice responsibilities described were performing patient education (99%), adjusting medication doses (98%), and conducting physical examinations (97%). More than 90% felt very or somewhat comfortable diagnosing rheumatoid arthritis (RA) and a similar percentage prescribed disease-modifying antirheumatic drugs. Three-quarters reported using disease activity measures for RA and 56% reported that their practices used TTT strategies.

CONCLUSION

Most respondents reported that they had substantial patient care responsibilities, used disease activity measures for RA, and incorporated TTT in their practice. These data suggest midlevel providers may help to reduce shortages in the rheumatology workforce and conform with recommendations to employ TTT strategies in RA treatment.

Investigating the contribution of physician assistants to primary care in England: a mixed-methods study

Background

Primary health care is changing as it responds to demographic shifts, technological changes and fiscal constraints. This, and predicted pressures on medical and nursing workforces, raises questions about staffing configurations. Physician assistants (PAs) are mid-level practitioners, trained in a medical model over 2 years at postgraduate level to work under a supervising doctor. A small number of general practices in England have employed PAs.

Objective

To investigate the contribution of PAs to the delivery of patient care in primary care services in England.

Design

A mixed-methods study conducted at macro, meso and micro organisational levels in two phases: (1) a rapid review, a scoping survey of key national and regional informants, a policy review, and a survey of PAs and (2) comparative case studies in 12 general practices (six employing PAs). The latter incorporated clinical record reviews, a patient satisfaction survey, video observations of consultations and interviews with patients and professionals.

Results

The rapid review found 49 published studies, mainly from the USA, which showed increased numbers of PAs in general practice settings but weak evidence for impact on processes and patient outcomes. The scoping survey found mainly positive or neutral views about PAs, but there was no mention of their role in workforce policy and planning documents. The survey of PAs in primary care (n = 16) found that they were mainly deployed to provide same-day appointments. The comparative case studies found that physician assistants were consulted by a wide range of patients, but these patients tended to be younger, with less medically acute or complex problems than those consulting general practitioners (GPs). Patients reported high levels of satisfaction with both PAs and GPs. The majority were willing or very willing to consult a PA again but wanted choice in which type of professional they consulted. There was no significant difference between PAs and GPs in the primary outcome of patient reconsultation for the same problem within 2 weeks, investigations/tests ordered, referrals to secondary care or prescriptions issued. GPs, blinded to the type of clinician, judged the documented activities in the initial consultation of patients who reconsulted for the same problem to be appropriate in 80% (n = 223) PA and 50% (n = 252) GP records. PAs were judged to be competent and safe from observed consultations. The average consultation with a physician assistant is significantly longer than that with a GP: 5.8 minutes for patients of average age for this sample (38 years). Costs per consultation were £34.36 for GPs and £28.14 for PAs. Costs could not be apportioned to GPs for interruptions, supervision or training of PAs.

Conclusions

PAs were found to be acceptable, effective and efficient in complementing the work of GPs. PAs can provide a flexible addition to the primary care workforce. They offer another labour pool to consider in health professional workforce and education planning at local, regional and national levels. However, in order to maximise the contribution of PAs in primary care settings, consideration needs to be given to the appropriate level of regulation and the potential for authority to prescribe medicines. Future research is required to investigate the contribution of PAs to other first contact services as well as secondary services; the contribution and impact of all types of mid-level practitioners (including nurse practitioners) in first contact services; the factors and influences on general practitioner and practice manager decision-making as to staffing and skill mix; and the reliability and validity of classification systems for both primary care patients and their presenting condition and their consequences for health resource utilisation.
