Research Partnerships with Healthcare Providers in Rural Community Health Centers: Needs and Challenges in Diabetes Research

Kentucky has among the highest rates of diabetes and obesity in the United States. The Kentucky Diabetes and Obesity Collaborative (KDOC) was designed to develop a novel research infrastructure that can be used by researchers focusing on obesity and diabetes among patients cared for by Federally Qualified Health Centers (FQHC) serving rural Kentucky. Focus groups were carried out to develop an understanding of the needs and interests of FQHC practitioners and staff regarding participation in KDOC. Focus groups were conducted with 6 FQHCs and included a total of 41 individuals including health care providers, administrative staff and clinical staff. The discussions ranged in time from 30 to 70 minutes and averaged 45 minutes. Analysis of the transcripts of the focus groups revealed 4 themes: 1) contextual factors, 2) infrastructure, 3) interpersonal relationships, and 4) clinical features. The participants also noted four requirements that should be met for a research project to be successful in rural primary care settings: 1) there must be a shared understanding of health priorities of rural communities between the researcher and the practices/providers; 2) the proposed research must be relevant to clinics and their communities; 3) research and recommendations for evidence-based interventions need to reflect the day-to-day challenges of rural primary care providers; and 4) there needs to be an understanding of community norms and resources. Although research-clinic partnerships were viewed favourably overall, challenges in data integration to support both research and clinical outcomes were identified.

Carbapenem-resistant Enterobacteriaceae rectal screening during an outbreak of New Delhi metallo-β-lactamase-producing Klebsiella pneumoniae at an acute care hospital

We describe the results of carbapenem-resistant Enterobacteriaceae (CRE) screening as part of an outbreak investigation of New Delhi metallo-β-lactamase-producing CRE at a tertiary care university teaching hospital. The manual method for CRE screening was useful for detecting patients with asymptomatic CRE carriage but was time-consuming and costly.

Increased resting energy expenditure is associated with failure to thrive in infants with severe combined immunodeficiency

OBJECTIVES

To measure resting energy expenditure (REE) and determine whether increased REE (hypermetabolism) is associated with failure to thrive (FTT) in patients with severe combined immunodeficiency (SCID) at diagnosis.

STUDY DESIGN

REE was measured in 26 patients with SCID in a single transplant center. Predicted REE was determined with World Health Organization standards. Measured REE >110% of predicted REE was classified as hypermetabolism. Other data collected included FTT status, infections, genotype, phenotype, and the feeding methods used.

RESULTS

Fifteen of 26 patients (57.7%) had FTT, and 18 of 26 patients (69.2%) were hypermetabolic. Hypermetabolism occured in 14 of 15 patients (93%) with FTT, and only 4 of 11 patients (36%) without FTT had hypermetabolism (P = .003). There was a significant difference between the measured REE (71.75 ± 16.6 kcal/kg) and the predicted REE (52.85 ± 2.8 kcal/kg; P < .0001). Eleven of 17 patients (65%) required nasogastric feeding, parenteral nutrition, or both to meet their energy needs.

CONCLUSIONS

Hypermetabolism is common in patients with SCID and may contribute to the development of FTT. The hypermetabolism in these patients may necessitate intensive nutrition support.

Cancer risk assessment by rural and Appalachian family medicine physicians

CONTEXT

Challenges to the identification of hereditary cancer in primary care may be more pronounced in rural Appalachia, a medically underserved region.

PURPOSE

To examine primary care physicians' identification of hereditary cancers.

METHODS

A cross-sectional survey was mailed to family physicians in the midwestern and southeastern United States, stratified by rural/non-rural and Appalachian/non-Appalachian practice location (n = 176). Identification of hereditary breast-ovarian cancer (BRCA1/2), hereditary non-polyposis colon cancer (HNPCC), and other hereditary cancers was assessed.

FINDINGS

Less than half of physicians (45%) reported having patients with cancer genetic testing. Most (70%) correctly identified the BRCA1/2-relevant scenario; 49% correctly identified the HNPCC-relevant scenario. Factor analysis of psychosocial variables revealed 2 factors: Confidence (knowledge, comfort, confidence) and importance (responsible, important, effective, need) of identifying hereditary cancer. Greater confidence was associated with use of 3 generation pedigree in taking family history. Greater knowledge and access to genetic services were associated with use of genetic testing. More recent graduation year, greater knowledge, and greater confidence were associated with identifying the BRCA1/2-relevant scenario. Greater knowledge and confidence were associated with identifying the HNPCC-relevant scenario.

CONCLUSIONS

Though rural Appalachian physicians do not differ in ability to identify high risk individuals, access barriers may exist for genetic testing. Interventions are needed to boost physician confidence in identifying hereditary cancer and to improve availability and awareness of availability of genetic services.

Pulmonary zygomycosis in solid organ transplant recipients in the current era

Fifty-eight solid organ transplant recipients with zygomycosis were studied to assess the presentation, radiographic characteristics, risks for extra-pulmonary dissemination and mortality of pulmonary zygomycosis. Pulmonary zygomycosis was documented in 31 patients (53%) and developed a median of 5.5 months (interquartile range, 2-11 months) posttransplantation. In all, 74.2% (23/31) of the patients had zygomycosis limited to the lungs and 25.8% (8/31) had lung disease as part of disseminated zygomycosis; cutaneous/soft tissue (50%, 4/8) was the most common site of dissemination. Pulmonary disease presented most frequently as consolidation/mass lesions (29.0%), nodules (25.8%) and cavities (22.6%). Patients with disseminated disease were more likely to have Mycocladus corymbifer as the causative pathogen. The mortality rate at 90 days after the treatment was 45.2%. In summary, pulmonary zygomycosis is the most common manifestation in solid organ transplant recipients with zygomycosis, and disseminated disease often involves the cutaneous/soft tissue sites but not the brain.

Nutritional issues in infants with cancer

Cancer and cancer therapy may have adverse effects on food intake, absorption and metabolism resulting in malnutrition. Malnutrition can adversely affect tolerance of therapy and hence overall survival. Malnutrition is of particular concern in infants and young children due to limited reserves and the effect undernutrition can play on a patient's weight gain, growth, immune function and overall well-being.

Vitamin K deficiency in children pre-bone marrow transplantation

This study examined the prevalence of vitamin K deficiency in children pre-bone marrow transplantation (BMT). Vitamin K status was measured by the PIVKA-II assay and prothrombin times. Blood samples were obtained before vitamin-containing TPN was infused. Results indicated that eight of 26 patients (31%) were vitamin K deficient; four cases were attributed to drug antagonism (phenytoin) and four were due to inadequate vitamin K intake, synthesis or malabsorption. Only one patient had a prolonged prothrombin time. Prothrombin time, in our study, is shown to be an ineffective screening tool to determine vitamin K status. All patients receiving phenytoin and chemotherapy are at increased risk of vitamin K deficiency.

Patients, practices, and relationships: challenges and lessons learned from the Kentucky Ambulatory Network (KAN) CaRESS clinical trial

The Cardiovascular Risk Education and Social Support (CaRESS) study is a randomized controlled trial that evaluates a social support intervention toward reducing cardiovascular risk in type 2 diabetic patients. It involves multiple community-based practice sites from the Kentucky Ambulatory Network (KAN), which is a regional primary care practice-based research network (PBRN). CaRESS also implements multiple modes of data collection. The purpose of this methods article is to share lessons learned that might be useful to others developing or implementing complex studies that consent patients in PBRNs. Key points include building long-term relationships with the clinicians, adaptability when integrating into practice sites, adequate funding to support consistent data management and statistical support during all phases of the study, and creativity and perseverance for recruiting patients and practices while maintaining the integrity of the protocol.

How and why to study the practice content of a practice-based research network

BACKGROUND

We describe the rationale, methods, and important lessons learned from doing a practice content study in a new practice-based research network (PBRN).

METHODS

We performed a modified replication of the National Ambulatory Medical Care Survey (NAMCS) in the Kentucky Ambulatory Network (KAN). Network clinicians had input into focused modifications of the NAMCS protocol, including addition of data fields of special interest to them. Cross-sectional sampling of patient visits was done for a 1-year period, with each practice collecting data during 2 separate weeks. We used selected results to illustrate lessons learned and the value of this endeavor.

RESULTS

Twenty-three KAN clinicians helped recruit 33 of their colleagues, and these 56 community-based primary care clinicians collected data on 2,228 office visits. Patient demographics (except race) and the top 10 diagnoses were similar to US NAMCS data. One third of visits addressed 3 or more diagnoses, and one fourth of the visits involved 4 or more medications. The top 10 primary diagnoses represented only one third of all primary diagnoses. Seventy percent of adult patients were either overweight (30%) or obese (40%). Rates of counseling on diet or exercise rose with increases in body mass index.

CONCLUSION

This study helped us establish and activate our new PBRN, increasing its membership in the process. The descriptive data gained will stimulate, guide, and support our future research activities.

Invasive mycotic infections caused by Chaetomium perlucidum, a new agent of cerebral phaeohyphomycosis

We report the first two cases of invasive human mycoses caused by the phaeoid ascomycete, Chaetomium perlucidum, and review the English literature regarding invasive Chaetomium infections. Fatal disseminated disease involving the brain, heart, lungs, and spleen is described in an acute myelogenous leukemia patient. A second patient with a history of asthma and chronic bronchiectasis experiencing right-middle-lobe syndrome grew C. perlucidum from lung tissue. This study adds C. perlucidum to the list of other known neurotropic Chaetomium species, C. atrobrunneum and C. strumarium, and also documents this organism's ability to disseminate beyond the central nervous system.

Efficacy and safety of radiologically placed gastrostomy tubes in paediatric haematology/oncology patients

BACKGROUND

The treatment of malnutrition, which is of great concern in paediatric haematology/oncology patients, is fraught with problems. The goals of our study were to document the complications and assess the weight gain with gastrostomy tubes (G-tubes) in this population.

PROCEDURE

Patient data were acquired by retrospective review of all haematology, oncology, and bone marrow transplant (BMT) patients (n = 44) who received radiologically placed G-tubes at our institution over a 4-year period.

RESULTS

Forty-four G-tubes were placed (59% peri-BMT). At tube placement, 55% of patients were malnourished and 45% were nourished. Seventy-five percent of patients had the procedure without general anaesthetic. Localized G-tube-site infection was the most common complication (41%). Major complications occurred in 3 patients; 2 patients experienced localized peritonitis, and 1 patient developed a localized collection of pus in the abdominal wall. There were no G-tube-related deaths. At 1 month after the tube insertion, 39% of patients had gained, 54% maintained, and 7% lost weight. At 3 months, 69% had gained, 28% maintained, and 3% lost weight. There was a statistically significant weight gain from the time of the G-tube placement to both 1 month (P < 0.018) and 3 months (P < 0.0001) after G-tube placement. Patients in all diagnosis categories showed improvement from 1 to 3 months.

CONCLUSIONS

We conclude that retrograde tube placement is safe and can frequently be done without general anaesthetic and that G-tube feeding effectively reverses malnutrition and prevents weight loss in this patient population.
