Examining the Utility of a Novel Neurologic Test in Patients With Obstructive Sleep Apnea: A Pilot Study.

Purpose: To test the association between participant King-Devick Test (KDT) times and obstructive sleep apnea (OSA) severity and evaluate for improvement after continuous positive airway pressure (CPAP) treatment. Methods: Study dates January 30 to July 31, 2018. Patients were referred for initial evaluation of sleep disordered breathing concerns. OSA severities were defined by Apnea Hypopnea Index (AHI) results, with ≥15 considered at least moderate OSA. The KDT is an objective physical measure of brain function. We estimated correlation between KDT time and AHI and compared mean KDT time between patients with and without moderate OSA. For the OSA subgroup, we evaluated for potential improvement in KDT after CPAP. Results: We enrolled 60 participants, of whom 35 (58.3%) had OSA with an AHI ≥15. Initial analyses noted no significant KDT time differences between patients based on OSA severity. However, after excluding 3 participants who had baseline neurologic illness, adjusted analyses demonstrated that mean KDT time was significantly prolonged for patients with moderate or greater OSA (AHI ≥15) as compared to those with mild or no sleep apnea (AHI <15); 63.4 seconds (95% CI 58.9-67.8) versus 55.7 seconds (95% CI 50.2-61.1), P = .03. CPAP-treated subjects demonstrated significantly improved KDT test times; 63.5 seconds mean pretreatment versus 55.6 posttreatment; -6.6 seconds mean difference, 95%CI (-12.0, -1.13), P = .02. Conclusion: Neurologic abnormalities in patients with OSA are potentially demonstrable utilizing this objective physical measure. Significant improvement is achieved in patients after CPAP treatment.

Impact of standardized templates and skin cancer learning modules for teledermatology consultations.

BACKGROUND: Little research has been done in teledermatology to examine the effects of standardized templates and subject-specific learning modules. METHODS: We performed a prospective study examining the effects of standardized templates and standardized cutaneous oncology learning modules on teledermatology referrals at Mayo Clinic. This data was then compared to previous teledermatology referrals before standardized templates were adopted. RESULTS: A total of 42 teledermatology consultations were performed during the 4-month study period. The use of standardized templates resulted in an absolute reduction in face-to-face referrals. Teledermatology consultation increased the absolute diagnostic and management concordance by 26.2% (P = 0.02) and 33.3% (P < 0.01), respectively, and decreased the absolute diagnostic and management discordance by 19.1% (P = 0.03) and 31.0% (P < 0.01), respectively. The largest knowledge gaps were identified in cutaneous oncology. Educational intervention improved theoretical referral rates and confidence in diagnosis and management overall. CONCLUSION: The implementation of standardized intake templates reduces the rate of face-to-face referrals. Teledermatology improves primary care-based dermatological care and reduces theoretical referral rates.

Family Medicine Panel Size with Care Teams: Impact on Quality.

PURPOSE: The demand for comprehensive primary health care continues to expand. The development of team-based practice allows for improved capacity within a collective, collaborative environment. Our hypothesis was to determine the relationship between panel size and access, quality, patient satisfaction, and cost in a large family medicine group practice using a team-based care model. METHODS: Data were retrospectively collected from 36 family physicians and included total panel size of patients, percentage of time spent on patient care, cost of care, access metrics, diabetic quality metrics, patient satisfaction surveys, and patient care complexity scores. We used linear regression analysis to assess the relationship between adjusted physician panel size, panel complexity, and outcomes. RESULTS: The third available appointments (P < .01) and diabetic quality (P = .03) were negatively affected by increased panel size. Patient satisfaction, cost, and percentage fill rate were not affected by panel size. A physician-adjusted panel size larger than the current mean (2959 patients) was associated with a greater likelihood of poor-quality rankings (≤25th percentile) compared with those with a less than average panel size (odds ratio [OR], 7.61; 95% confidence interval [CI], 1.13-51.46). Increased panel size was associated with a longer time to the third available appointment (OR, 10.9; 95% CI, 1.36-87.26) compared with physicians with panel sizes smaller than the mean. CONCLUSIONS: We demonstrated a negative impact of larger panel size on diabetic quality results and available appointment access. Evaluation of a family medicine practice parameters while controlling for panel size and patient complexity may help determine the optimal panel size for a practice.

Use of FRAX as a determinant for risk-based osteoporosis screening may decrease unnecessary testing while improving the odds of identifying treatment candidates.

PURPOSE: We have assessed the hypothetical impact of guideline-concordant osteoporosis screening on baseline behaviors utilizing two different guidelines and determined the relative ability of each to identify osteoporosis treatment candidates. METHODS: We conducted secondary analyses from the Fracture Risk Perception Study, which enrolled patients aged 50 to 75 years to complete questionnaires about their bone health. We determined our baseline screening rates and detection of treatment candidates and then assessed the hypothetical impact of adherence to U.S. Preventive Services Task Force (USPSTF) and National Osteoporosis Foundation (NOF) criteria, particularly for women aged 50 to 64. RESULTS: Of 144 women aged 50 to 64 years screened, 14 (9.7%) were treatment candidates. Screening based on identification of one or more risks (NOF) would lead to testing of 102 of the 144 patients (71%) to identify 12 of 14 treatment candidates (86%). Applying USPSTF criteria (9.3% FRAX threshold) would test 45 of the same 144 women (31%) to identify 11 of 14 treatment candidates (79%). NOF risk-based criteria would result in a moderate absolute screening rate reduction (16%, p = .0011; 95% CI, 7%-25%), but only marginal improvement in identifying treatment candidates (odds ratio, 2.67; 95% CI, 0.57-12.47). Applying the more selective USPSTF criteria greatly reduced unnecessary testing (56% absolute screening rate reduction; p < .0001; 95% CI, 47%-64%) while further improving the odds of identifying treatment candidates (odds ratio, 10.35; 95% CI, 2.72-39.35). CONCLUSIONS: When contemplating screening younger patients, systematic calculation of FRAX and ordering only when the 9.3% fracture risk threshold is reached may decrease unnecessary screening for many women while still identifying appropriate osteoporosis treatment candidates.

Fracture risk perception study: patient self-perceptions of bone health often disagree with calculated fracture risk.

BACKGROUND: We sought to evaluate the concordance between self-assessed perceptions of fracture risk and actual risk calculated by World Health Organization's 10-year Fracture Risk Assessment Tool (FRAX). METHODS: We collected demographic data, lifestyle information, osteoporosis knowledge, bone density test results, and treatment history from patients aged 50 to 75 years. Subjects rated their perceptions of 10-year risk of sustaining fracture as low (0%-9%), intermediate (10%-19%), or high (≥20%). This rating was compared with risk calculated by FRAX. FINDINGS: Among 426 patients, the greatest agreement regarding fracture risk was noted for those in the low-risk FRAX group: 81% perceived themselves as having low risk. The most risk disagreement was in the high-risk FRAX group: Only 18% perceived their risk as high. Perceived risk was intermediate for 59% and low for 24%. Of patients at intermediate calculated risk by FRAX, 48% agreed with this with self-perceived risk. Overall, risk agreement was associated with bone density results, with higher T scores predictive of agreement. Underestimation was associated with being female and older. Patients with prescription treatment exposure frequently had risk disagreement and perceived their risk as lower than their calculated FRAX scores might indicate. Patients taking calcium and vitamin D similarly perceived lower risk than calculated by FRAX. CONCLUSIONS: Patients at intermediate and high calculated fracture risk frequently had self-perceptions of lower risk. Patients taking prescription osteoporosis medication and calcium and vitamin D treatment perceived less risk than calculated. Whether correcting misperceptions about personal susceptibility to fracture might result in behavioral changes will be determined.

Utilising the epidemiologic triad in analysing quality improvement data: antibiotic use for respiratory infections as a case example.

BACKGROUND: Quality improvement investigators working in field settings, who typically are not trained in epidemiological methods, may not consider all three elements of the epidemiologic triad (person, place and time) when planning their projects. AIM: To demonstrate how the epidemiological triad can guide analysis for quality assessment. Predictors of antibiotic use in primary care were analysed to illustrate the approach. METHODS: This study was a secondary analysis of data previously collected from medical records and a provider survey. A convenience sample of 467 family medicine patients treated in two clinic sites for acute respiratory tract infections was analysed by locating quality variation in person, place and time. Independent variables included patient age, date of clinic visit, and clinic site. The outcome measure was antibiotic prescription (yes or no). RESULTS: Antibiotics were prescribed for 69.2% of patients in the sample. Age group was not related to antibiotic prescribing. Prescription was related to time (P = 0.0344) and clinic site (P = 0.0001) in univariate tests. However, only site was independently related to antibiotic prescription (odds ratio = 0.47, confidence interval = 0.30 to 0.73, P = 0.0008). CONCLUSION: The epidemiological triad assisted in guiding further post hoc analysis of predictors of antibiotic prescriptions. Further investigations of this quality indicator can be directed at exploring site differences and testing interventions. Studies of other quality indicators in primary care can employ the triad to guide the analysis.

Addressing antibiotic use for acute respiratory tract infections in an academic family medicine practice.

The objective of this study was to educate health care providers and patients to reduce overall antibiotic prescription rates for patients with acute respiratory tract infection (ARTI). An interdisciplinary quality improvement team used the Define, Measure, Analyze, Improve, and Control quality improvement process to change patient expectations and provider antibiotic prescribing patterns. Providers received personal and group academic detailing about baseline behaviors, copies of treatment guidelines, and educational materials to use with patients. Get Smart About Antibiotics Week materials educated patients about appropriate antibiotic use. Providers collected demographic and clinical information about a case series of patients with ARTIs and their subsequent provision of antibiotics. In total, 241 patients with ARTIs were accrued. The antibiotic prescribing rate for patients aged 18 years and older was significantly reduced from 69% at baseline to 56% after interventions (95% confidence interval = 49.1%-63.4%; P<.001). Providers' prescribing behaviors significantly improved after multiple quality improvement interventions.

Acute respiratory tract infection: a practice examines its antibiotic prescribing habits.

PURPOSE: We wanted to better understand our practice behaviors by measuring antibiotic prescribing patterns for acute respiratory tract infections (ARTIs), which would perhaps help us delineate goals for quality improvement interventions. We determined (1) the distribution of ARTI final diagnoses in our practice, (2) the frequency and types of antibiotics prescribed, and (3) the factors associated with antibiotic prescribing for patients with ARTI. METHODS: We looked at office visits for adults with ARTI symptoms that occurred between December 14, 2009, and March 4, 2010. We compiled a convenience sample of 438 patient visits, collecting historical information, physical examination findings, diagnostic impressions, and treatment decisions. RESULTS: Among the 438 patients, cough was the most common presenting complaint (58%). Acute sinusitis was the most frequently assigned final diagnosis (32%), followed by viral upper respiratory tract infection (29%), and acute bronchitis (24%). Sixty-nine percent of all ARTI patients (304/438) received antibiotic prescriptions, with macrolides being most commonly prescribed (167/304 [55%]). Prescribing antibiotics was associated with a complaint of sinus pain or shortness of breath, duration of illness ≥8 days, and specific abnormal physical exam findings. Prescribing rates did not vary based on patient age or presence of risk factors associated with complication. Variations in prescribing rates were noted between individual providers and groups of providers. CONCLUSIONS: We found that we prescribed antibiotics at high rates. Diagnoses of acute sinusitis and bronchitis may have been overused as false justification for antibiotic therapy. We used broad-spectrum antibiotics frequently. We have identified several gaps between current and desired performance to address in practice-based quality improvement interventions.

Mitochondrial myopathy presenting as rhabdomyolysis.

A 37-year-old white woman presented with acute bilateral hamstring pain after hiking. She had a creatine kinase level of 11,144 U/L. Rhabdomyolysis was diagnosed and the patient was admitted for intravenous fluid hydration. The patient continued to have exercise-induced myalgias and elevations in her creatine kinase level. Rheumatologic causes were ruled out and results from electromyogram testing were nondiagnostic. A muscle biopsy revealed a mitochondrial myopathy. The 22 mitochondrial DNA and transfer RNA genes were sequenced. An A-to-G transition was found at nucleotide position 4281 in the transfer RNA isoleucine gene. The patient was placed on a regimen of riboflavin, vitamin C, and coenzyme Q10, which provided mild relief. The patient returned to the emergency department 2 more times after vigorous exercise, with creatine kinase levels as high as 2800 U/L. At last follow-up, the patient was using a fentanyl citrate transdermal patch, which enabled her to perform moderate exercise without pain.

Urinary tract infection in women over the age of 65: is age alone a marker of complication?

BACKGROUND: We were interested to know if our older female patients with urinary tract infections (UTIs) might have differing pathogens or rates of Escherichia coli antibiotic sensitivity and if our physicians managed them in a manner similar or dissimilar to the care provided to younger patients with no complications. METHODS: This was a secondary analysis from patients excluded from a previous retrospective study regarding uncomplicated UTIs. RESULTS: Twenty-six percent of total patients with UTIs were older than 65 and otherwise medically uncomplicated whereas 21% were older patients who did have complicating factors. E. coli was a pathogen in 81% of uncomplicated elders' and 54% of complicated elders' cultures. E. coli sensitivity rate to sulfamethoxazole-trimethoprim (SMX/TMP) in both groups was 86%. Physicians were significantly less likely to prescribe SMX/TMP for complicated older patients with complications than for young patients with an uncomplicated UTI (P = .017); there was a significant trend of physicians to be less likely to prescribe SMX/TMP with advancing age in a patient and complications across all 3 groups (P = .011). Antibiotics rarely needed to be changed after cultures. CONCLUSIONS: The presence of E. coli on culture in patients with a UTI changes based on medical complications, not age. Being medically complex did not result in reduced sensitivity of E. coli to SMX/TMP but was associated with increased rates of the presence of other pathogens. In our setting, treatment employed with SMX/TMP and without the use of culture and sensitivity may be effective for appropriately selected older women. Prospective studies are needed to determine the optimal approach to management.

Assessing adherence to evidence-based guidelines for the diagnosis and management of uncomplicated urinary tract infection.

OBJECTIVE: To assess adherence to evidence-based guidelines for the diagnosis and management of uncomplicated urinary tract infection (UTI) in a family medicine residency clinic setting. PATIENTS AND METHODS: We retrospectively reviewed the medical records of female patients seen in 2005 at the Mayo Clinic Family Medicine Center in Scottsdale, Ariz, who were identified by International Classification of Diseases, Ninth Revision code 599.0 (UTI). We assessed documentation rates, use of diagnostic studies, and antibiotic treatments. Antibiotic sensitivity patterns from outpatient urine culture and sensitivity analyses were determined. RESULTS: Of 228 patients, 68 (30%) had uncomplicated UTI. Our physicians recorded essential history and examination findings for most patients. Documentation of the risk of sexually transmitted disease differed between residents and attending physicians and was affected by patient age. Urine dipstick and urine culture and sensitivity analyses were ordered in 57 (84%) and 52 (76%) patients, respectively. Eighty percent of patients with positive results on urine dipstick analyses also had urine culture and sensitivity analyses. Sulfamethoxazole-trimethoprim (SMX-TMP) was used as initial therapy in 26 patients (38%). Sixty-one percent of SMX-TMP and ciprofloxacin prescriptions were appropriately provided for 3 days. Escherichia coil was sensitive to SMX-TMP in 33 (94%) of 35 cultures. Treatment was not changed in any patient with an uncomplicated UTI because of results of urine culture and sensitivity analyses. Antibiotic sensitivity patterns for outpatients were significantly different from those for inpatients. CONCLUSION: Only 30% of our patients had uncomplicated UTI, making their management within clinical guidelines appropriate. However, of those patients with uncomplicated UTI, less than 25% received empirical treatment as suggested. Urine culture and sensitivity analyses were performed frequently, even in patients who already had positive results on a urine dip-stick analysis. Although SMX-TMP is effective, it is underused. On the basis of these findings, we hope to provide interventions to increase SMX-TMP prescription, decrease use of urine culture and sensitivity analyses, and increase the frequency of 3-day antibiotic treatments at our institution.
