The Changing Faces of Mentorship: Application of a Developmental Network Framework in a Health Services Research Career Development Program

Historically, mentorship has been conceived of as a dyadic relationship between a senior mentor and an early‐career investigator. Models involving multiple mentors have gained favor in recent years, but empirical research on multiple‐mentor models has been lacking. The current work aims to fill this gap by describing a long‐standing health services research mentoring program at the U.S. Department of Veterans Affairs which has adopted a network‐based approach to mentoring. As part of a broader project, we surveyed VA HSR&D Career Development Awardees who received an award between 2000 and 2012. In total, 133 awardees participated (84%). Awardees reported on the structure of mentoring relationships with their two most influential mentors. Awardees were mentored by teams consisting of one to five mentors (M = 2.7 mentors). Most often, one mentor served as primary mentor while one or more mentors played a supporting role. In most cases, an awardee‘s primary mentor was co‐located with the awardee, with fewer secondary mentors co‐located. More recently funded CDAs had more mentors and were less likely to be co‐located with secondary mentors. The VA HSR&D CDA program incorporates current thinking about Developmental Network models of mentorship into a comprehensive program providing a rich mentorship experience for its awardees.     

Rapid nighttime evacuation of a veterans hospital

Loss of essential utilities and danger of explosion forced a rapid nighttime winter evacuation of 229 patients from an acute-care Veterans Administration hospital. Although distribution of patients to recipient hospitals was not optimal, and the location of several patients could not be documented for more than 24 hours, the evacuation in subfreezing weather went smoothly. Continuity of care and careful planning permitted an orderly return to the hospital five days later. Although financial costs were high, no excess mortality or morbidity was associated with the evacuation. No changes in pharyngeal gram-negative bacterial flora of the patients were noted. Further, a critique is presented to aid in planning for similar emergencies elsewhere.     

Exploring the application of the Charlson Comorbidity Index to assess the patient population seen in a Veterans Affairs chiropractic residency program

ObjectiveChiropractic trainees require exposure to a diverse patient base, including patients with multiple medical conditions. The Veterans Affairs (VA) Chiropractic Residency Program aims for its doctor of chiropractic (DC) residents to gain experience managing a range of multimorbid cases, yet to our knowledge there are no published data on the comorbidity characteristics of patients seen by VA DC residents. We tested 2 approaches to obtaining Charlson Comorbidity Index (CCI) scores and compared CCI scores of resident patients with those of staff DCs at 1 VA medical center.MethodsTwo processes of data collection to calculate CCI scores were developed. Time differences and agreement between methods were assessed. Comparison of CCI distribution between resident DC and staff DCs was done using 100 Monte Carlo simulation iterations of Fisher''s exact test.ResultsBoth methods were able to calculate CCI scores (n = 22). The automated method was faster than the manual (13 vs 78 seconds per patient). CCI scores agreement between methods was good (κ = 0.67). We failed to find a significant difference in the distribution of resident DC and staff DC patients (mean p = .377; 95% CI, .375–.379).ConclusionCCI scores of a VA chiropractic resident''s patients are measurable with both manual and automated methods, although automated may be preferred for its time efficiency. At the facility studied, the resident and staff DCs did not see patients with significantly different distributions of CCI scores. Applying CCI may give better insight into the characteristics of DC trainee patient populations.     

Factors Influencing Receipt of Early Rehabilitation After Stroke

Objective

To identify patient-level characteristics associated with rehabilitation during the acute poststroke phase.

Design

Retrospective cohort. Generalized estimating equations modeled the likelihood of rehabilitation during the index hospitalization to account for patient clusters.

Setting

Rehabilitation facilities.

Participants

Sample included veterans (N=9681; average age, 68.7y; 97.4% men) diagnosed with new stroke discharged from Veterans Affairs hospitals between October 1, 2006, and September 30, 2008.

Interventions

Not applicable.

Main Outcome Measure

Receipt of rehabilitation services.

Results

Of the total cohort, 73% received some type of rehabilitation. After adjustment, stroke patients with cerebral arteries occlusion were most likely to receive rehabilitation compared with other stroke types (P<.001). Patients with prestroke conditions of metastatic cancer (odds ratio [OR]=.68, P<.001) and psychosis (OR=.90, P=.045) were less likely to have rehabilitation, whereas those with hypertension (OR=1.26, P<.001) and other neurologic disorders (OR=1.29, P<.001) were more likely. Compared with patients admitted from home, patients transferred from a non-Veterans Affairs hospital (OR=1.4, P<.004) were more likely to receive rehabilitation, whereas patients admitted from extended care (OR=.59, P<.001) were less likely. Married veterans were less likely to receive rehabilitation services (OR=.87, P<.001) than unmarried veterans.

Conclusions

Within the Veterans Health Administration, initiating rehabilitation in the acute phase poststroke appears to be influenced by patient clinical characteristics and living circumstances.     

Factors influencing receipt of outpatient rehabilitation services among veterans following lower extremity amputation

Zhou J, Bates BE, Kurichi JE, Kwong PL, Xie D, Stineman MG. Factors influencing receipt of outpatient rehabilitation services among veterans following lower extremity amputation.

Objective

To determine patient-, treatment-, and facility-level characteristics associated with receiving outpatient rehabilitation services after lower extremity amputation within the Veterans Affairs (VA) system.

Design

Observational study.

Setting

All Veterans Affairs Medical Centers (VAMCs).

Participants

Veterans (N=4165) with lower extremity amputation discharged from VAMCs between October 1, 2002, and September 20, 2004.

Interventions

Not applicable.

Main Outcome Measures

Receipt of outpatient rehabilitation services up to 1 year postdischarge. A Cox proportional hazards model was used to determine the adjusted hazard ratio and 95% confidence interval of veterans to receive outpatient services.

Results

Sixty-five percent of veterans with lower extremity amputation received outpatient services. Older veterans, patients admitted for surgical amputation from extended care rather than transferred from another hospital, and those with transfemoral and/or bilateral rather than unilateral transtibial amputations were less likely to receive outpatient services. Those with serious comorbidities and those who had procedures for acute central nervous system disorders, active cardiac pathology, serious nutritional compromise, and severe renal disease during the surgical hospitalization less often initiated outpatient care. Patients who received inpatient consultative rehabilitation compared with inpatient specialized rehabilitation, and who were treated in the Northeast compared with the Southeast less often initiated outpatient care. Finally, those discharged to home or other locations rather than extended care had an initial increased likelihood of receiving outpatient service, but by 180 days postdischarge those discharged to extended care were more likely to initiate outpatient services.

Conclusions

Both clinical characteristics and types of rehabilitation services received appear to influence the receipt of outpatient rehabilitation services. Geographic location also affected the receipt of outpatient rehabilitation, suggesting that care patterns are not standardized across the nation.     

Screening for Mild Traumatic Brain Injury in the Presence of Psychiatric Comorbidities

Chapman JC, Andersen AM, Roselli LA, Meyers NM, Pincus JH. Screening for mild traumatic brain injury in the presence of psychiatric comorbidities.

Objective

To determine whether or not a battery of neurobehavioral tests, the Brief Objective Neurobehavioral Detector (BOND), could detect mild traumatic brain injury (mTBI) among a group of psychiatric inpatients with numerous substance-related and medical comorbidities. The 16-item BOND is comprised of neurologic examination tasks and has been shown to correlate with radiologic and cognitive findings in previous studies.

Design

Masked comparison.

Setting

Inpatient psychiatric unit at the Veterans Affairs Medical Center in Washington, DC.

Participants

Patients (N=51) sequentially admitted for suicidal ideation in the context of various psychiatric disorders.

Interventions

No intervention.

Main Outcome Measure

BOND total and subtest scores.

Results

Forty-three patients were eligible and analyzed. Twenty-seven had sustained an mTBI in the distant past, and 16 had never sustained a traumatic brain injury (TBI) (non-TBI group). On average, the mTBI group demonstrated a significantly greater number of abnormal subtests on the BOND (mean, 7.22) than did the non-TBI group (mean, 4.50; P=.003). Although the BOND significantly correlated with the presence of mTBI, it did not correlate with any of the psychiatric, substance-related, or medical comorbidities. Multiple regressions indicated that the BOND total score was not explained by age, posttraumatic stress disorder diagnosis, or any combination of the psychiatric, substance-related, or medical comorbidities. High rates of sensitivity (70%) and specificity (69%) were found.

Conclusions

The results of this pilot study suggest that the inexpensive, brief, and objective BOND instrument may be a useful screening tool for the detection of subtle neurologic brain abnormalities after mTBI, even in the presence of substantial comorbidities.     

Correlation of Body Composition and Low Back Pain Severity in a Cross-Section of US Veterans

Objective

Back pain is more prevalent in the obese, but whether back pain severity is directly correlated to obesity in veterans is unknown. We sought to determine if there was a correlation between body composition and low back pain severity in a sample of veterans. The hypothesis was that veterans with higher body mass index values would report higher low back pain severity scores.

The Department of Veterans Affairs Nursing Academy (VANA): forging strategic alliances with schools of nursing to address nursing's workforce needs

In 2007, the Department of Veterans Affairs (VA) established the VA Nursing Academy (VANA), a 5-year, $60-million pilot program funding 15 partnerships between schools of nursing and local VA health care facilities nationwide, to expand nursing faculty, enhance clinical faculty development, increase nursing student enrollment, and promote educational innovations. VA is an ideal setting for educating nursing students owing to a well-educated registered nurse staff, an array of traditional and nontraditional settings, a state-of-the-art computerized electronic health record system, and a unique patient population. Challenges related to the complex nature of VANA partnerships, conceptualized as strategic alliances created between disparate subunits, each embedded in a larger organization, require careful governance to ensure smooth implementation. To ensure the program’s aims are met, a 6-year national evaluation has been funded to help identify which strategies best achieve VANA’s goals. The speed of economic recovery and the resulting changes in the nursing workforce are important determinants of VANA’s future.     

Risk of stroke, heart attack, and diabetes complications among veterans with spinal cord injury

Banerjea R, Sambamoorthi U, Weaver F, Maney M, Pogach LM, Findley T. Risk of stroke, heart attack, and diabetes complications among veterans with spinal cord injury.

Objectives

To compare the rates of diabetes and macrovascular conditions in veterans with spinal cord injury (SCI) and to examine variations by patient-level demographic, socioeconomic, access, and health status factors.

Design

A retrospective analysis. Diabetes status was classified by merging with diabetes epidemiology cohort using a validated algorithm. Chi-square tests and logistic regressions used to compare rates in macro- and microvascular conditions in veterans with and without diabetes.

Setting

Veteran Health Administration clinic users in fiscal year (FY) 1999 to FY 2001.

Participants

SCI patients (N=8769) with diabetes (n=1333), in FY 2000, identified through the SCI registry.

Interventions

Not applicable.

Main Outcome Measures

Macrovascular and microvascular conditions in the next year (February 2001). Derived from International Statistical Classification of Diseases, 9th Revision, Clinical Modification, codes in the patient treatment files.

Results

Overall, 15% of SCI veterans were identified with diabetes but this was an underestimate due to high mortality (8%). Among SCI veterans with diabetes, 49% had at least one macrovascular condition and 54% had microvascular conditions compared with 24% and 25% of those without diabetes (P<.001).

Conclusions

Our study highlights the highly significant relationship between diabetes and macro- and microvascular conditions in veterans with SCI. Neurologic deficit combined with increased insulin resistance has a greater macrovascular impact on SCI veterans than on those who do not have diabetes. Increasing age and physical comorbidities compound the problem.     

Patterns of opioid use for chronic noncancer pain in the Veterans Health Administration from 2009 to 2011

Although opioids are frequently prescribed for chronic noncancer pain (CNCP) among Veterans Health Administration (VHA) patients, little has been reported on national opioid prescribing patterns in the VHA. Our objective was to better characterize the dosing and duration of opioid therapy for CNCP in the VHA. We analyzed national VHA administrative and pharmacy data for fiscal years 2009 to 2011. For individuals with CNCP diagnoses and any opioid use in the fiscal year, we calculated the distribution of individual mean daily opioid dose, individual total days covered with opioids in a year, and individual total opioid dose in a year. We also investigated the factors associated with being in the top 5% of individuals for total opioid dose in a year, which we term receipt of high-volume opioids. About half of the patients with CNCP received opioids in a given fiscal year. The median daily dose was 21 mg morphine equivalents. Approximately 4.5% had a mean daily dose higher than 120 mg morphine equivalents. The median days covered in a year was 115 to 120 days in these years for those receiving opioids. Fifty-seven percent had at least 90 days covered with opioids per year. Major depression and posttraumatic stress disorder were positively associated with receiving high-volume opioids, but nonopioid substance use disorders were not. Among VHA patients with CNCP, chronic opioid therapy occurs frequently, but for most patients, the average daily dose is modest. Doses and duration of therapy were unchanged from 2009 to 2011.     

Does the presence of a specialized rehabilitation unit in a Veterans Affairs facility impact referral for rehabilitative care after a lower-extremity amputation?

OBJECTIVE: To determine if the presence of specialized rehabilitation units (SRUs) within Veterans Affairs medical centers (VAMC) influences access to rehabilitation services. DESIGN: Retrospective cohort analysis. SETTING: Two types of VAMCs: those with and without SRUs. PARTICIPANTS: Veterans with lower-extremity amputations discharged from VAMCs between October 1, 2002, and September 30, 2003. There were a total of 2375 veterans with amputations: 99% were men; and 60% had transtibial, 40% had transfemoral, and less than 1% had hip disarticulation amputations. Nine hundred sixty-six patients (41%) were seen at a VAMC with an SRU. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Level of service provided expressed as: no evidence of rehabilitation during the hospitalization, generalized rehabilitation through consultation only, or admission to an SRU. RESULTS: There were no differences between patients treated at facilities with SRUs and those treated in a facility without SRU beds with respect to age, sex, marital status, source of hospital admission, or level of amputation (all P<.05). Patients with lower initial FIM instrument scores were more likely to be treated in facilities with SRUs, and to have longer lengths of acute hospitalization (P<.01). Patients at facilities with an SRU compared with those without an SRU had comparable likelihoods of being seen for an initial rehabilitation consultation (75% vs 74%, P=.56), but were more likely to be admitted for high intensity specialty rehabilitation services (26% vs 11%, P<.01). CONCLUSIONS: Although the majority of patients were seen in consultation, structural differences in service availability among clinically similar populations appear to be causing access disparities to specialized rehabilitation among amputees in the VAMC setting. The implication of these differences with regard to patient outcomes will need to be determined.     

“We really need this”: Trauma-informed yoga for Veteran women with a history of military sexual trauma

ObjectivesUp to 70% of women service members in the United States report military sexual trauma (MST); many develop post-traumatic stress disorder (PTSD) and co-occurring disorders. Trauma-informed yoga (TIY) is suggested to improve psychiatric symptoms and shown feasible and acceptable in emerging research, yet no work has evaluated TIY in MST survivors. The current quality improvement project aimed to examine TIY’s feasibility, acceptability, and perceived effects in the context of MST.DesignCollective case series (N = 7).SettingNew England Vet Center.InterventionsExtant TIY program (Mindful Yoga Therapy) adapted for Veteran women with MST in concurrent psychotherapy.Main outcome measuresAttrition and attendance; qualitative exit interview; validated self-report measure of negative affect pre/post each yoga class, and symptom severity assessments and surveys before (T1; Time 1) and after the yoga program (T2; Time 2).ResultsFeasibility was demonstrated and women reported TIY was acceptable. In qualitative interviews, women reported improved symptom severity, diet, exercise, alcohol use, sleep, and pain; reduced medication use; and themes related to stress reduction, mindfulness, and self-compassion. Regarding quantitative change, results suggest acute reductions in negative affect following yoga sessions across participants, as well as improved affect dysregulation, shame, and mindfulness T1 to T2.ConclusionsTIY is both feasible and acceptable to Veteran women MST survivors in one specific Vet Center, with perceived behavioral health benefits. Results suggest TIY may target psychosocial mechanisms implicated in health behavior change (stress reduction, mindfulness, affect regulation, shame). Formal research should be conducted to confirm these QI project results.     

Evaluation of selected laboratory components of a comprehensive periodic health evaluation for veterans with spinal cord injury and disorders

OBJECTIVE: To evaluate selected laboratory components of a comprehensive periodic health evaluation program for patients with spinal cord injury and disorders (SCI/D). DESIGN: A retrospective study. SETTING: A Department of Veterans Affairs spinal cord injury center. PARTICIPANTS: Community-dwelling male veterans with SCI/D (N=350). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Proportion of laboratory tests that resulted in new diagnoses (diagnostic yield) and proportion of laboratory tests that resulted in changes in management (therapeutic yield). RESULTS: Although abnormality rates for many routine laboratory tests were high (up to 31.5%), diagnostic and therapeutic yields were low (<1.5%), with the exception of glucose (therapeutic yield, 3.4%) and lipid tests (up to a 4.1% diagnostic and 15.2% therapeutic yield). CONCLUSIONS: Our data revealed that diagnostic and therapeutic yields for many laboratory components of the annual PHE program for veterans with SCI/D were low, consistent with findings in the general ambulatory population. Further data collection, particularly prospective longitudinal data, may help optimize the selection and frequency of laboratory tests performed as part of this program.     

Chiropractic Integrated Care Pathway for Low Back Pain in Veterans: Results of a Delphi Consensus Process

Objective

The purpose of this study was to develop an integrated care pathway for doctors of chiropractic, primary care providers, and mental health professionals who manage veterans with low back pain, with or without mental health comorbidity, within Department of Veterans Affairs health care facilities.

Evaluation of the Efficacy and Safety of a Hydrochlorothiazide to Chlorthalidone Medication Change in Veterans With Hypertension

Background

There are few data available examining the clinical impact of switching patients from hydrochlorothiazide (HCTZ) to chlorthalidone for blood pressure management.

Objectives

The goal of this study was to compare within-patient clinic blood pressure readings, serum electrolyte levels, and renal function markers before and after a medication change from HCTZ to chlorthalidone in a veteran population.

Methods

This was a retrospective, pre- and postmeasure, self-controlled study. Veterans Affairs Ann Arbor Healthcare System patients switched from HCTZ to chlorthalidone between January 1, 2001, and January 31, 2012, who had at least 1 follow-up clinic blood pressure reading recorded between 2 and 8 weeks from the date of the medication change were included in the study. Mean pre- and postmeasure values for systolic and diastolic clinic blood pressures, serum potassium, serum sodium, serum calcium, serum creatinine, and blood urea nitrogen were compared by using a 2-tailed, paired t test with a significance level (α) of 0.05.

Results

Of the 40 patients included in the study 95% were male, 65% were white, and the mean age was 64.9 (10.8) years. Both mean systolic (–15.8 mm Hg [95% CI, 8.9 to 22.6], P < 0.0001) and mean diastolic (–4.2 mm Hg [95% CI, 1.5 to 6.9], P = 0.0035) blood pressures showed statistically and clinically significant reductions after the medication change. A statistically significant decrease in mean sodium (–1.1 mmol/L [95% CI, 0.4 to 1.9], P = 0.003) and an increase in mean serum creatinine (0.06 mg/dL [95% CI, –0.09 to –0.02], P = 0.002) was observed; however, these changes may not be viewed as clinically significant by many practitioners. No statistically significant changes were observed in any of the other outcomes examined. Most patients (38 of 40) were taking at least 1 additional antihypertensive agent; 73% of patients were using ≥3 antihypertensive agents at the time of the medication change.

Conclusions

In patients with hypertension already taking HCTZ, switching to chlorthalidone seems to further reduce systolic and diastolic blood pressures without any clinically significant changes in renal function or electrolyte levels.     

Factors Associated With Home Discharge Among Veterans With Stroke

Objective

To determine which patient-, treatment-, and facility-level characteristics were associated with home discharge among patients hospitalized for stroke within the Department of Veterans Affairs.

Design

Retrospective observational study.

Setting

Veterans Affairs facilities nationwide.

Participants

Veterans hospitalized for stroke during fiscal year 2007 to fiscal year 2008 (N=12,565).

Intervention

Not applicable.

Main Outcome Measure

Discharge location after hospitalization.

Results

There were 10,130 (80.6%) veterans discharged home after hospitalization for acute stroke. Married veterans were more likely than nonmarried veterans to be discharged home (odds ratio [OR]=1.23; 95% confidence interval [CI]=1.11–1.35). Compared with veterans admitted to the hospital from home, patients admitted from extended care were less likely to be discharged home (OR=.04; 95% CI=.03–.07). Compared with those with occlusion of cerebral arteries, patients with intracerebral hemorrhage (OR=.61; 95% CI=.50–.74) or other central nervous system hemorrhage (OR=.78; 95% CI=.63–.96) were less likely to be discharged home, whereas patients with occlusion of precerebral arteries (OR=1.36; 95% CI=1.07–1.73) were more likely to return home. Evidence of congestive heart failure (OR=.85; 95% CI=.76–.95), fluid and electrolyte disorders (OR=.86; 95% CI=.77–.96), internal organ procedures and diagnostics (OR=.87; 95% CI=.78–.97), and serious nutritional compromise (OR=.49; 95% CI=.40–.62) during hospitalization remained independently associated with lower odds of home discharge. Longer hospitalizations and receipt of rehabilitation services while hospitalized acutely were negatively associated, whereas treatment on more bed sections and rehabilitation accreditation of the facility were positively associated with home discharge. Region exerted a statistically significant effect on home discharge.

Conclusions

We found sociological, clinical, and facility-level factors associated with home discharge after hospitalization for acute stroke. Findings document the importance of considering a broad range of characteristics rather than focusing only on a few specific traits during discharge planning.
