Complementary and Alternative Medicine Use by Primary Care Patients with Chronic Pain

OBJECTIVES To describe the characteristics and attitudes toward complementary and alternative medicine (CAM) use among primary care patients with chronic pain disorders and to determine if CAM use is associated with better pain control. DESIGN Cross-sectional survey. SUBJECTS Four hundred sixty-three patients suffering from chronic, nonmalignant pain receiving primary care at 12 U.S. academic medical centers. OUTCOME MEASURE Self-reported current CAM usage by patients with chronic pain disorders. RESULTS The survey had an 81% response rate. Fifty-two percent reported current use of CAM for relief of chronic pain. Of the patients that used CAM, 54% agreed that nontraditional remedies helped their pain and 14% indicated that their individual alternative remedy entirely relieved their pain. Vitamin and mineral supplements were the most frequently used CAM modalities. There was no association between reported use of CAM and pain severity, functional status, or perceived self-efficacy. Patients who reported having at least a high school education (odds ratio [OR] 1.1, 95% confidence interval [CI] 1.02-1.19, P = 0.016) and high levels of satisfaction with their health care (OR 1.47, 95% CI 1.13-1.91, P = 0.004) were significantly more likely to report using CAM. CONCLUSIONS Complementary and alternative therapies were popular among patients with chronic pain disorders surveyed in academic primary care settings. When asked to choose between traditional therapies or CAM, most patients still preferred traditional therapies for pain relief. We found no association between reported CAM usage and pain severity, functional status, or self-efficacy.

Feasibility of Extended-interval Follow-up for Patients Receiving Warfarin.

AIMS The 2012 American College of Chest Physician Evidence-Based Management of Anticoagulant Therapy guidelines suggest an international normalized ratio (INR) testing interval of up to 12 weeks, rather than every 4 weeks, for patients with consistently stable INRs while taking vitamin K antagonists. We aimed to examine the feasibility of extended-interval follow-up in a real-world setting. METHODS Patients receiving stable warfarin therapy for ≥ 12 weeks at baseline began extended-interval follow-up with visits occurring at 6 weeks, 14 weeks, and every 12 weeks thereafter to a maximum of 68 weeks or until they were no longer suitable for extended-interval follow-up. A single INR excursion >0.3 from goal was permitted if a reversible precipitating factor was identified and the INR was expected to return to goal without dose adjustment. The primary outcome was the proportion of patients completing all study follow-up visits. RESULTS Of 48 patients enrolled, 47 had evaluable data. The most common indication for anticoagulation was atrial fibrillation/flutter (53.2%). At baseline, mean prior warfarin treatment duration was 6.7 ± 6 years and median number of weeks on a stable regimen was 24 weeks (IQR, 19-37.5). Eleven patients (23%) completed all study follow-up visits, whereas 17 (36%) did not maintain a stable INR past the 14-week follow-up. CONCLUSION A large proportion of patients with previously stable (≥ 3 months) INRs were not able to maintain stable INRs during extended-interval follow-up. More research is needed to identify patient characteristics predictive of success with extended-interval follow-up prior to broad implementation.

Arriving at correct conclusions: the importance of association, causality, and clinical significance.

Declaring that a causal and not solely a correlative relation exists between a risk factor and a disease creates significant implications for patients and physicians. No matter the forum, when investigators or clinicians make such a claim, it is essential to explain how this determination was made so that appropriate recommendations are made in all areas of our professional practice. When we review the medical literature it is similarly crucial to understand this distinction between causality and association. The Bradford Hill criteria of strength of association, consistency, temporality, biological gradient, biological plausibility, coherence, experimental evidence, and analogy can be used to help establish causality. It is also important to understand the distinction between clinical and statistical significance to complete our appraisal of the implications of a clinical study. Statistically significant results, although not the result of chance, may be clinically insignificant. Statistically insignificant results, conversely, may not exclude the possibility of a clinically important relation. This article reviews the concepts of causality and association and clinical versus statistical significance and provides examples from the literature.

Perioperative medication errors in otolaryngology

Medication errors are a common cause of poor clinical outcomes. Information on perioperative medication errors is scarce. This study was aimed at identifying the nature, cause, and potential remedies for medication errors in otolaryngologic surgery.

A 3-minute test of cardiorespiratory fitness for use in primary care clinics

Background Cardiorespiratory fitness (CRF) is the only major risk factor that is not routinely assessed in the clinical setting, for preventive medicine. A valid and practical CRF test is needed for use in the clinics. The objective of this study is to demonstrate the validity of a 3-minute squat test to assess CRF in primary care. Methods A cross-sectional study in which the participants performed both the Ruffier squat test and the Balke maximal treadmill test. The study was conducted in a clinical setting from September 2016 to March 2017. We recruited a convenient sample of 40 adults between 18 and 64 years from the general U.S. population. Participants completed 30 squats in 45 seconds, paced by a metronome. Heart rate was measured at rest (P1), immediately after the test (P2), one minute after the test (P3). V˙O2max was measured using the Balke maximal treadmill fitness test. Results Of the 40 participants, there were 18 men and 22 women. Mean age was 31.2 years (SD = 9.9). We found that the best V˙O2max predictors were HR features P1/height and (P2–P3)/age3. Our best-performing model using these two features predicted individuals’ CRF levels with an adjusted R2 of 0.637, sensitivity of 0.79, and specificity of 0.56. Conclusions The study provided strong evidence for the validity of the squat test in the clinical setting. Further, the equation of our model along with V˙O2max normative tables provides an efficient and easy way to assess CRF in a primary care setting.

Evaluation of the Appropriateness of Direct Oral Anticoagulant Selection and Monitoring in the Outpatient Setting

Background: Direct oral anticoagulants (DOACs) share many indications with warfarin but require less frequent follow-up and monitoring. There is limited data available on the prescribing of DOACs and appropriate laboratory monitoring in a real-world clinical setting. Objective: To determine if patients receiving care at 2 University of Florida (UF) Health Internal Medicine clinics are prescribed DOACs according to Food and Drug Administration (FDA)–approved labeling. Secondary objectives were to determine the percentage of patients receiving appropriate baseline laboratory tests prior to DOAC initiation and the frequency of laboratory monitoring. Methods: This retrospective chart review evaluated patients enrolled at 2 UF Health Internal Medicine practices within the UF Health system who were prescribed a DOAC between April 2014 and April 2015. Adherence to FDA-approved dosing recommendations and baseline laboratory tests were compared to previously published data. This study was approved by the UF Institutional Review Board. Results: A total of 194 patients met inclusion criteria. Ninety-six patients (49.5%) were on a DOAC prior to data collection; 98 patients (50.5%) started a DOAC during data collection. Of the 194 patients, 155 (79.9%) were prescribed DOACs per FDA-approved labeling (P = .0005); 79 (40.8%) obtained a complete blood count, serum creatinine, and liver function tests prior to DOAC initiation. Conclusions: Prescribing practices were significantly better than published data; however, 1 in 5 patients were not prescribed a DOAC according to FDA-approved labeling. Less than half of the patients started on a DOAC obtained the recommended labs prior to medication initiation.

Sodium chloride pica causing recurrent nephrolithiasis in a patient with iron deficiency anemia: a case report

BackgroundIron deficiency anemia is a common finding in women of child-bearing age. Pica, or the ingestion of non-food or non-nutritive items, is a well-known manifestation of iron deficiency. A high sodium diet increases risk for nephrolithiasis. We describe the case of a 31-year-old woman with recurrent calcium nephrolithiasis and anemia who ate ice chips as well as spoons of salt daily. Treatment of pica may prove effective in preventing recurrent nephrolithiasis.Case presentationA 31-year-old white woman with a past medical history of menorrhagia, anemia, and recurrent calcium nephrolithiasis presented for preoperative evaluation prior to ureterolithotomy. She described a daily pattern of eating continually from a cup of ice chips accompanied by multiple spoons of salt directly out of a salt shaker. These cravings had been present for many years, were bothersome to her, and interfered with her daily life. Laboratory findings revealed hemoglobin of 10.9 g/dL with ferritin of 3 ng/mL. History, physical, and laboratory data were consistent with pica secondary to iron deficiency anemia. She was prescribed orally administered ferrous sulfate 325 mg three times a day with meals. She continues to struggle with the symptoms of pica and orally administered supplementation.ConclusionsIt is important that clinicians consider the possible diagnosis of sodium chloride pica in patients with iron deficiency anemia and recurrent nephrolithiasis. Treatment of anemia and resolution of pica may prove effective in preventing future nephrolithiasis. Specific questioning about pica symptoms in patients with iron deficiency anemia and recurrent nephrolithiasis may be helpful diagnostically and therapeutically.
