Antibiotics and return visits for respiratory illness: a comparison of pooled versus hierarchical statistical methods.

BACKGROUND: Antibiotic prescribing for respiratory illness has been associated with small reductions in return visits in an analysis of a large practice-based network. In this study, we apply hierarchical analytical methods that account for the clustering of patients by practices to identify whether antibiotic prescribing by primary care physicians reduces subsequent visits for 6 acute respiratory illnesses-upper respiratory infection, pharyngitis, bronchitis, otitis media, sinusitis, and cough. METHODS: The study data came from 318 family physicians and internists in 45 practices in the Practice Partner Research Network from January 1995 through December 1996, with 255,564 active patients. Patients treated with antibiotics were compared with those who were not on the frequency of revisit within the next 14 days. A simple pooling model and 3 hierarchical statistical models (fixed-effects, random-effects, and Bayesian) were used to compare the odds-ratios for return visits. RESULTS: Statistically significant results were found only for bronchitis and sinusitis by the hierarchical models, but the simple pooling model produced statistically significant results for all study conditions. CONCLUSION: We conclude that antibiotics may reduce return visits for patients with bronchitis and sinusitis, but not for patients with other respiratory illness (upper respiratory infection, pharyngitis, otitis media, or cough). Studies of large clinical databases should use methods of analysis that account for the grouping of patients by practice to avoid false positive associations (type I errors.)

Medical students' abilities to take an occupational history: use of the WHACS mnemonic.

This study examined medical students' use of the WHACS mnemonic during an occupational history objective structured clinical examination station. Students' performance on the 10 content-specific station items was calculated. Factor analysis of the items was conducted, and student demographic and academic characteristics associated with performance on the station were examined. A total of 205 students completed the station. The mean number of correct responses was 5 (SD, 1.6). Students performed well on some items and less well on others. Factor analysis supported the WHACS framework. There were no significant associations with student demographic or academic characteristics. Students were aware of the particular features of an occupational history but were deficient in other areas; this awareness was not related to demographic or academic characteristics. The WHACS mnemonic could be an effective tool to teach occupational history-taking skills.

The pharmacist's role in promoting optimal antimicrobial use.

Optimal use of antimicrobials is essential in the face of escalating antibiotic resistance, and requires cooperation from all sectors of the health care system. Although antibiotic-restriction policies in the hospital setting are important in altering microbial susceptibility patterns, an overall reduction in antibiotic prescriptions in the outpatient setting is more likely to significantly impact antibiotic resistance. Education of providers, application of clinical practice guidelines, audit and feedback activities, and multifaceted interventions all have had an effect in altering antibiotic prescribing in a research setting. Clinicians must alter antibiotic prescribing for the treatment of infectious diseases, and patients must change their perception of the need for these drugs. Pharmacists can play a major role through clinician education and focused clinical services. With cooperation of health care teams, the effectiveness of available antibiotics may be sustained and the threat of resistance minimized.

An evaluation of statewide strategies to reduce antibiotic overuse.

BACKGROUND: The rapid increase of antibiotic resistance poses a significant threat to human health. Overuse of antibiotics has been linked to rates of antibiotic resistance. This study assessed the utility of two common interventions--1) practice profiling and feedback and 2) patient education materials--implemented to decrease antibiotic prescribing for pediatric upper respiratory infections (URIs). METHODS: Based on Medicaid regions in Kentucky, primary care physicians managing pediatric respiratory infections in Medicaid were randomized into four groups. Groups received either 1) performance feedback only, 2) patient education materials only, 3) both feedback and education materials, or 4) no intervention. Participating physicians had their antibiotic prescribing assessed for the period of July 1, 1996, to November 30, 1997, with an intervention in June 1997. The study included 216 physicians and 124,092 episodes of care. RESULTS: All groups increased in proportion of episodes with antibiotics between the pre-intervention and post-intervention periods. Prescribing in the patient education group and the patient education and feedback group increased at a significantly lower rate than in the control group. Physicians did not change their coding of illness to justify antibiotics after the intervention, and there was no significant generalization of effect of the pediatric intervention on prescribing for adult URIs. CONCLUSIONS: These interventions demonstrate little if any impact on promoting appropriate antibiotic prescribing. Antibiotic prescribing for viral respiratory infections continues to increase, suggesting concomitant increases in antibiotic resistance.

Challenges to academic family medicine in the current health care environment.

BACKGROUND: Changes in health care delivery and funding have placed strains on academic medical centers' ability to meet their multiple missions. To gain insight into how this new academic landscape is affecting academic primary care, this study examined the current status and perceived challenges at nine departments of family medicine at allopathic and osteopathic medical schools. METHODS: Site visits were made to nine academic departments of family medicine where key informant interviews were conducted with several individuals in key leadership positions. Sites were chosen to maximize diversity among departments along a variety of factors, such as location, size, mission, and type of school (private versus public). Interviews were transcribed and analyzed by a three-person multidisciplinary team for key themes. RESULTS: Analysis of interviews revealed five major challenges for academic departments of family medicine: 1) adjusting to new clinical demands in the academic health center, 2) organizing and administering new initiatives in community-based education, 3) recruiting and retaining faculty, 4) developing and maintaining research capacity, and 5) serving multiple missions (education, clinical care, and academic pursuits) in times of financial restraint. CONCLUSIONS: Significant challenges face academic departments of family medicine. The success or failure of departments of family medicine to meet these challenges could serve as a bellwether for how primary care fits into the future overall scheme of academic health centers.

Responding to patients' emotions: important for standardized patient satisfaction.

BACKGROUND AND OBJECTIVES: Several experts have emphasized the need to respond to a patient's emotions as an essential component of effective medical interviewing. This study examined the relationship of faculty observers' scores of students' performance in standardized patient (SP) interviewing stations in a family medicine clerkship objective structured clinical examination (OSCE) with SP satisfaction measures. METHODS: The faculty observers scored students in the following performance domains: 1) interviewing skills, 2) negotiating the diagnosis or plan, 3) gathering case-specific content information, 4) responding to the patient's emotions, and 5) student's overall performance. Pearson Product-Moment correlations were calculated for each of these domains and the Standardized Patient Satisfaction Questionnaire (SPSQ) scores. RESULTS: There were moderate correlations between the SPSQ score and the overall OSCE score (.45) and the response to patient's emotions skill score (.36). The faculty observer's response to patient's emotion score correlated highly with the student's overall OSCE score (.75). CONCLUSIONS: A student's ability to respond to the patient's emotions appears to be an important skill for successful medical interviewing from both the faculty observer's perspective and the SP's perspective. Results also demonstrate that the SP's perspective is similar, but not identical, to the faculty observer's perspective, suggesting that SPs have an important evaluative role in student assessment.

Does acute bronchitis really exist? A reconceptualization of acute viral respiratory infections.

BACKGROUND: Considerable overlap exists in patient presentations and physical findings in viral upper respiratory tract infections (URIs) and acute bronchitis. Our goal was to determine whether there are any clinical cues that could help physicians differentiate between these 2 conditions. METHODS: We performed a retrospective chart audit on 135 patients who had been given a diagnosis of acute bronchitis and a random sample of 409 patients with URIs over a 2.5-year period. Patient and provider characteristics, patient symptoms, and physical findings were compared with bivariate analyses and then entered into a logistic regression model. RESULTS: In bivariate analyses, a number of demographic variables, symptoms, and signs were associated with acute bronchitis. Multivariate analysis showed that the strongest independent predictors of acute bronchitis were cough (adjusted odds ratio [AOR]=21.12; 95% confidence interval [CI], 6.01-74.26), and wheezing on examination (AOR=12.16; 95% CI, 5.39-27.42). Nausea was the strongest independent predictor that the diagnosis would not be acute bronchitis (AOR=0.01; 95% CI, 0.01-0.85). However, there was considerable overlap between the 2 conditions, and the logistic model explained only 37% of the variation between the diagnoses. CONCLUSIONS: We hypothesize that sinusitis, URI, and acute bronchitis are all variations of the same clinical condition (acute respiratory infection) and should be conceptualized as a single clinical entity, with primary symptoms related to different anatomic areas rather than as different conditions.

Predictors of antibiotic prescribing for nonspecific upper respiratory infections, acute bronchitis, and acute sinusitis. An UPRNet study. Upper Peninsula Research Network.

BACKGROUND: Antibiotics are often prescribed for viral respiratory infections. The goal of our study was to determine the factors associated with antibiotic prescribing for acute respiratory infections in primary care. METHODS: We performed an observational study in 15 primary care practices in Michigan using patient and physician surveys distributed during visits for acute respiratory infections. We included patients 4 years or older presenting with symptoms of an acute respiratory infection (n=482). The main outcome measures were prescriptions of antibiotics, signs and symptoms associated with antibiotic prescribing, and clinician-reported reasons for prescribing an antibiotic. RESULTS: We found that patients who were older than 18 years, sick for more than 14 days, and seen in urgent care clinics were more likely to receive antibiotics. Patients expected antibiotics if they perceived that the drug had helped with similar symptoms in the past. In an adjusted model, the variables significantly associated with antibiotic prescribing were physical findings of sinus tenderness (odds ratio [OR]=20.0; 95% confidence interval [CI], 8.3-43.2), rales/rhonchi (OR=19.9; 95% CI, 9.2-43.2), discolored nasal discharge (OR=11.7; 95% CI, 4.3-31.7), and postnasal drainage (OR=3.1; 95% CI, 1.6-6.0). The presence of clear nasal discharge on examination was negatively associated (OR=0.3; 95% CI, 0.2-0.5). CONCLUSIONS: Several physical signs play an important role in clinicians' decisions to prescribe antibiotics for respiratory infections. This information will be useful in designing interventions to decrease inappropriate antibiotic prescribing for upper respiratory infections.

Continuity of care and the physician-patient relationship: the importance of continuity for adult patients with asthma.

BACKGROUND: We assessed the role and importance of continuity of care in predicting the perceptions of the physician-patient relationship held by patients with asthma. METHODS: We analyzed the 1997 statewide probability survey of adult Kentucky Medicaid recipients. The participants included 1726 respondents with 2 or more visits to a physician's office, clinic, or emergency department in the previous 12 months. Of these, 404 reported having asthma. The respondents used 5-point single-item scales to rate continuity of care, provider communication, and patient influence over treatment. RESULTS: Multivariate linear regression analyses were used to assess the contribution of continuity of care to provider communication and patient influence in the presence of control variables. Those variables included age, sex, education, race, number of visits, general health, health improvement, and life satisfaction. For persons with asthma, continuity of care was the only variable that significantly contributed to the provider communication model (P = .01) and the only variable other than life satisfaction that contributed to the patient influence model (P < .05 for each). For patients who did not have asthma, continuity of care was one of several variables contributing significantly (P < .05) to the provider communication and patient influence models. CONCLUSIONS: Particularly for patients with asthma, continuity of care was linked to patient evaluations of their interaction with the physician. Because of this, changes in health care systems that promote discontinuity with individual physicians may be particularly disruptive for patients with chronic diseases.

Patient satisfaction with care in programs for low income individuals.

Although a variety of public and private programs provide care for low-income individuals, little is known about patient satisfaction across these programs. The objective of this study was to examine patient satisfaction across a variety of health insurance programs. A survey was conducted of randomly selected adults in Kentucky who had an outpatient visit in the past 12 months (616 with private insurance, 683 Medicaid recipients, 287 in private sector charity program for uninsured indigents). Patient satisfaction with multiple dimensions of their most recent outpatient visit was assessed. All insurance groups were generally satisfied with the care received in their most recent visit. For all 8 dimensions of patient satisfaction, the private insurance group was significantly higher than the other groups. In a model controlling for standard demographic and health status variables, higher overall satisfaction with the visit was positively related to higher income and higher mental health functional status. The insurance category variable had no significant relationship to overall satisfaction with the visit. Although patients receiving care through health insurance programs for low-income individuals are generally satisfied with the services, there is an indication that low-income individuals, regardless of insurance type, are less satisfied with the care they receive.

Practice patterns for peptic ulcer disease: are family physicians testing for H. pylori?

BACKGROUND: Peptic ulcer disease (PUD) is a problem common in family medicine. Recent evidence of Helicobacter pylori as an etiological agent of PUD has led to National Institutes of Health recommendations for treatment to eradicate H. pylori through antibiotic therapy. The purpose of this study is to examine practice patterns of family physicians in treating PUD, their use of H. pylori testing, and knowledge of current recommendations for PUD. MATERIALS AND METHODS: A mail survey was sent to a random sample of 1,500 members of the American Academy of Family Physicians. Six hundred thirty useable surveys (49.1%) were available for analysis. Descriptive statistics were obtained, as were inferential statistics focusing on the relationship of physician background characteristics to practices. RESULTS: Thirty-eight percent of the respondents order diagnostic procedures for the majority (50% or more) of their suspected PUD cases. Of the physicians who reported ordering any diagnostic tests, 52% ordered the combination of upper gastrointestinal series and endoscopic gastroduodenoscopy. For patients with clinical diagnoses of PUD, 77% of doctors reported ordering a diagnostic test for H. pylori. Approximately 68% were aware that some kind of guidelines existed; only 11% reported that they were familiar with the National Institutes of Health recommendations for PUD. CONCLUSIONS: Although some of the practices of family physicians for treatment of PUD deviate from current recommendations, the majority of practices are consistent with current evidence.

Alcohol use in adolescent females: correlates with estradiol and testosterone.

This study investigated if self-reports of alcohol use correlated with estradiol and testosterone levels in adolescent females. Ninety-four female senior high school student volunteers from 2 schools completed a questionnaire regarding alcohol use. Twenty cc of blood was assayed for estradiol, testosterone, progesterone, and FSH. Total estradiol levels were higher in females who reported current alcohol use (p < or = 0.05), and females with higher levels of both testosterone and estradiol were more likely to be using alcohol currently (p < or = 0.05). Hormonal relationships associated with adolescent alcohol use may be related to future health risks of alcohol use and/or increased risk of alcohol use.

Survey of clinical pharmacists' knowledge of appropriateness of antimicrobial therapy for upper respiratory infections and acute bronchitis.

We conducted a survey to assess clinical pharmacists' recommendation of antibiotics for upper respiratory infections (URIs) and acute bronchitis. A random sample of 752 members of the American College of Clinical Pharmacy were mailed a multiple-choice survey that presented four examples consistent with clinical symptoms of the two disorders. Respondents were asked what treatment they would recommend for each example. The response rate was 59%. Pharmacists recommended antibiotics for the treatment of both URIs and acute bronchitis significantly more if patients' symptoms included discolored discharge or sputum as opposed to clear discharge. Those who were board certified were less likely than nonboard-certified pharmacists to recommend antibiotics for URIs with discolored discharge. Pharmacists who specialized in either ambulatory care or infectious disease were less likely than those in other specialties to recommend antibiotics for acute bronchitis with discolored sputum. Clinical pharmacists are similar to patients and physicians in their belief that antibiotics are appropriate for URIs and acute bronchitis with discolored discharge. Considering the role that pharmacists play as clinical consultants to physicians, greater efforts should be made to educate them regarding appropriate prescription of antibiotics.

Access to care for the uninsured: is access to a physician enough?

OBJECTIVES: This study examined a private-sector, statewide program (Kentucky Physicians Care) of care for uninsured indigent persons regarding provision of preventive services. METHODS: A survey was conducted of a stratified random sample of 2509 Kentucky adults (811 with private insurance, 849 Medicaid recipients, 849 Kentucky Physicians Care recipients). RESULTS: The Kentucky Physicians Care group had significantly lower rates of receipt of preventive services. Of the individuals in this group, 52% cited cost as the primary reason for not receiving mammography, and 38% had not filled prescribed medicines in the previous year. CONCLUSIONS: Providing free access to physicians fills important needs but is not sufficient for many uninsured patients to receive necessary preventive services.

Personality disorder traits: prevalence and effects on health status in primary care patients.

OBJECTIVE: Previous work in an academic setting has found that scoring in the higher ranges for selected personality disorders on an objective assessment tool was associated with increases in psychiatric co-morbidities, decreased satisfaction with health care, and diminished health related functional status. This study examines how often patients in primary care practices exhibit traits consistent with these selected disorders and what impact this has on their health related functional status and use of health care resources. METHODS: Thirteen family practices agreed to distribute questionnaires to 50 consecutive patients in the spring of 1997. Questionnaires contained instruments that assess risk for personality disorders, health related functional status, health resource use, demographics, and depression. The relationships between four specific personality disorders (borderline, dependent, schizoid and schizotypal) and other assessed variables were explored. RESULTS: Of the 250 patients returning completed survey instruments, 80 (32%) scored in the high range for traits consistent with one of the four target personality disorders. Patients in the high risk group also were noted to have more outpatient, emergency, and inpatient visits in the previous six months. Those in the high risk group also had significantly lower scores on seven of eight measures of health related functional status. CONCLUSIONS: Patients who have several traits for borderline, dependent, schizoid, and schizotypal personality disorders are common in primary care practices. These patients utilize services at higher rates than others and are more likely to screen in the positive range for depressive symptoms and have overall lower health related functional status.
