Influences on consumer spending for herbal products.

BACKGROUND: Despite the rapid growth in consumer spending on herbal products, we know little about factors that influence such spending. OBJECTIVE: To use a model of adoption to investigate consumers' spending on herbal products. METHODS: The study used a mail survey of a stratified random sample of 1,300 consumers. The population consisted of consumers aged 18 years and older residing in the United States. The sampling frame was a mailing list purchased from KM Lists. The independent variables were consumer characteristics, social systems, communication channels, and herbal characteristics. The amount of spending on herbs was the dependent measure, with responses divided into monthly spending of 10 dollars or less and more than 10 dollars . Binary logistic regression was performed to investigate the association between adoption model variables and spending on herbs. RESULTS: Of the 1,300 mailed surveys, there were 77 undeliverable surveys and 456 usable returned surveys, yielding a usable response rate of 37.3%. A total of 181 (39.7%) respondents reported using herbal products. The logistic regression was performed using the 168 herbal users who reported that they spent money in the past month on herbal products. The overall regression model was significant (P<.05, Nagelkerke R(2)=0.499). The significant influences on spending on herbals were age, over-the-counter (OTC) drug use, and use of an herb professional as an information source about herbs. Older people reported spending more on herbal products than younger people. OTC drug use was positively related to spending on herbals and appears to complement herbal usage. Finally, consumers who obtain information about herbals from an herb professional tend to spend more on herbals. CONCLUSION: An adoption model may be useful in explaining consumers' spending on herbal products.

Examining gender salary disparities: an analysis of the 2003 multistate salary survey.

BACKGROUND: Pharmacist salary and wage surveys have been conducted at the state and national level for more than 20 years; however, it is not known to what extent, if any, wage disparities due to gender still exist. OBJECTIVES: The overall objective of this study was to determine if wage disparities exist among male and female pharmacists at the multistate and individual state level for each of 6 states studied. A secondary objective was to explore the effect of various demographic variables on the hourly wages of pharmacists. METHODS: Data were collected from 1,688 pharmacists in 6 states during 2003 using a cross-sectional descriptive survey design. A multiple regression analysis on hourly wage testing the effects of state of practice, practice setting, position, terminal degree, and years in practice was conducted. Subsequent multiple regression analyses were conducted individually for each of the 6 states to test the effects of the above variables on hourly wage for both male and female pharmacists, followed by state-level analyses for male and female pharmacists, respectively. RESULTS: For the pooled data, all variables were found to be significant predictors of hourly wage, except for earning a PharmD degree without a residency or graduate degree. Gender was not a significant predictor of wage disparities in the state-level analyses. Position was the only significant predictor of wage disparities in all states (except Tennessee) such that pharmacists in management positions make significantly higher salaries than those in staff positions. CONCLUSIONS: The results of these analyses suggest that wage disparities due to gender do not exist at the state level for the 6 states surveyed, when controlling for practice setting, position, terminal degree, and years in practice. The larger number of men in management positions may explain lower wages for female pharmacists.

Relationship between physician knowledge of hypertension and blood pressure control.

The purpose of this study was to evaluate the cross-sectional relationship between physician knowledge of hypertension guidelines and blood pressure (BP) control. The authors evaluated a sample of primary care faculty (n=32) and a sample of their patients (n=613). When treating patients as independent observations, the authors found an inverse relationship (r=-0.524; p=0.002) where higher knowledge scores were associated with lower BP control. The authors conducted a multivariate analysis to accommodate the nonindependence due to random physician effects and found that there was no longer a significant association between knowledge and BP control, but there was still a trend (odds ratio=0.84; p=0.130). This study demonstrates that there is no evidence that high knowledge of hypertension guidelines will improve BP control rates and that higher knowledge may actually be associated with lower BP control. Strategies that are designed only to improve knowledge of hypertension guidelines are insufficient to improve BP control rates.

Practitioner activities in patient education and drug therapy monitoring for community dwelling elderly patients.

We compared the frequency of performance of three patient education and three drug therapy monitoring activities across practitioner types and assessed the influence of practitioner characteristics, practice setting, and health care environment on performance of these activities. A mail survey was sent to a random sample of 1300 practitioners in a Midwestern state. Numbers of elderly patients for whom the practitioner performed each of the activities were the dependent variables. Independent variables for the multiple regressions were measures of practitioner characteristics, practice setting, and health care environment. Based on 320 usable responses, prescribers were more likely than pharmacists to perform three of the activities. Minutes per patient contact was positively associated with two of the monitoring activities. Other practitioners in a practice affected the number of patients for whom five activities were performed. Practitioners interested in improving the medication use process for ambulatory elderly patients need to consider multidisciplinary strategies.

Drug information-seeking intention and behavior after exposure to direct-to-consumer advertisement of prescription drugs.

BACKGROUND: Concerns about direct-to-consumer advertisement's (DTCA's) information quality have raised interest in patients' drug information-seeking after DTCA exposure. OBJECTIVE: To identify predictors of patients' intentions and behaviors to seek drug information from physicians, pharmacists, and the Internet after DTCA exposure, using theories of planned behavior and self-efficacy. METHODS: One thousand patients were randomly selected from 3,000 nationwide osteoarthritic patients. A self-administered survey examined predictors of intention including measurements of attitude toward behavior, subjective norm, perceived difficulty, self-efficacy, controllability, self-identity, intention, exposure to ads, and control variables. After 6 weeks, another survey measured respondents' information-seeking behavior. For patients exposed to DTCA, 6 multiple regressions were performed for information-seeking intention and behavior for 3 information sources: physicians, pharmacists, and the Internet. RESULTS: The response rates were 61.9% and 80.1% for the first survey and the second survey, respectively. Four hundred and fifty-four participants reported exposure to DTCA about arthritis prescription medicines in the previous month. Over 41% of the variance in intention and over 18% of the variance in behavior were explained by the regression procedures. The consistent positive predictors of intention were attitude toward behavior, self-identity, attitude toward DTCAs of arthritis medication, and osteoarthritis pain; while the consistent positive predictors of behavior were intention and osteoarthritis pain. The strongest predictors of intention were self-identity for physicians, subjective norm for pharmacists, and attitude toward behavior for the Internet. Perceived difficulty and self-efficacy did not predict intention, and self-efficacy and controllability did not predict behavior. CONCLUSIONS: DTCA-prompted drug information-seeking may be under patients' complete volitional control. To promote information searching, efforts could be made to affect factors predicting intention. Interventions could address patients' attitude toward behavior, the influence of their important others, and their role as information seeker, respectively, for information sources like the Internet, pharmacists, and physicians.

Factors affecting collaborative care between pharmacists and physicians.

BACKGROUND: To have a positive impact on patient outcomes achieved with drug therapy, it is likely that pharmacists will work more closely with physicians to manage medications collaboratively. Yet, little is known about the factors that will support such collaborative care between pharmacists and physicians. OBJECTIVE: The objective of this study was to identify significant influences on collaborative care between pharmacists and physicians, from the perspective of pharmacists. METHODS: Data were collected through a survey mailed to a national sample of 321 pharmacists identified by state pharmacy associations as being innovative practitioners. Three types of influences were assessed: individual characteristics, contextual factors, and exchange characteristics. Individual characteristics included demographics and a personality measure. Context variables included practice environment and professional interactions between pharmacists and physicians. Exchange characteristics were trustworthiness, role specification, and relationship initiation. Four items asked about the pharmacist's collaborative care with a physician. A hierarchical linear regression analysis was performed with collaborative care as the dependent variable and the individual, context, and exchange characteristics as the independent variables. RESULTS: One hundred sixty-six usable surveys (53.4%) were returned. About 64% of the respondents were male, with a mean age of 43.7 (SD+/-11.2) years. Linear regression analysis of the complete model produced an R(2)=0.805 (P<.001). Significant predictors in the model included the context variable, professional interaction, and the exchange characteristics, trustworthiness and role specification. CONCLUSION: Overall, the collaborative working relationship model largely explained collaborative care between pharmacists and physicians. Researchers are encouraged to use these findings when studying pharmacist-physician collaboration. In addition, pharmacists seeking to work with physicians should attend to developing trustworthiness and clarifying their clinical roles with physicians.

Comprehensive medication therapy management: identifying and resolving drug-related issues in a community pharmacy.

OBJECTIVE: The aim of this study was to characterize comprehensive medication therapy management (MTM) involving a community pharmacy and local physicians by describing the drug-related issues encountered, identifying which medication types were associated with these issues, and listing the actions taken by physicians and pharmacists to address them. METHODS: In the MTM program studied, community pharmacists and physicians worked together to manage the drug therapy of ambulatory Iowa Medicaid recipients dispensed > or =4 medications for chronic conditions by a community pharmacy. After initial assessment, pharmacists made written recommendations to the patient's physician, and the physicians subsequently responded. Data were extracted from pharmacy records for patients who made > or =1 visit during the first 2 years of the program. Collected data included patient demographics, number of chronic conditions and medications at enrollment, type and number of drug-related issues, medication category, pharmacist recommendations, and physician acceptance of recommendations. RESULTS: Data were gathered for 150 patients. The mean (SD) age was 54.4 (19.4) years and 74.0% were female. They were taking a mean (SD) of 9.3 (4.6) medications and had a mean (SD) of 6.1 (3.1) medical conditions at enrollment. A total of 886 drug-related issues were classified into 7 categories: inappropriate adherence (25.9%), needs additional therapy (22.0%), wrong drug (13.2%), unnecessary drug therapy (12.9%), adverse drug reaction (11.1%), dose too low (9.7%), and dose too high (5.3%). Overall, physicians accepted 313 (47.4%) of the 659 recommendations to alter drug therapy made by pharmacists, with the highest rates of agreement to stop or change a medication (50.3% and 50.0%, respectively) and the lowest rate of agreement to start a new medication (41.7%). CONCLUSION: The MTM program showed that drug therapy for ambulatory patients taking multiple medications to treat chronic conditions can be improved through collaboration between physicians and community pharmacists.

Population-based medication reviews: a descriptive analysis of the medication issues identified in a medicare not-for-profit prescription discount program.

BACKGROUND: Medication reviews may be an important strategy to improve medication use, especially for individuals receiving many drugs. OBJECTIVE: To describe the types of medication issues and recommendations identified in the Iowa Priority Brown Bag Medication Reviews, compare individuals with medication issues with those without medication issues, and describe Iowa Priority enrollees' experiences with and satisfaction of the review. METHODS: A retrospective review of enrollment forms and medication review records and a survey of Iowa Priority members were conducted in 2002. Subjects were Medicare-eligible individuals who joined the Iowa Priority Prescription Savings Program. Frequency distributions and descriptive statistics were calculated. Analysis using t-test and chi(2) test determined differences between individuals with and without issues regarding use of drug therapy. RESULTS: Almost 13% of Iowa Priority enrollees received a review. There were 1167 individuals with 2123 medication issues identified. Nonprescription medications accounted for one-third of drug interactions and >40% of duplications. People with issues had poorer health, more chronic conditions, and took more drugs than people without medication issues. One-third of survey respondents discussed the review with their physicians, and 17.7% reported medication changes. Satisfaction with the review was good; however, only 24% were likely to have received an annual review. CONCLUSIONS: Iowa Priority Brown Bag Medication Reviews showed that individuals with fair/poor health, higher numbers of medications, and more chronic conditions were likely to have medication issues. Reviews generated discussions between physicians and patients, produced some medication changes, and helped individuals save money.

Influential characteristics of physician/pharmacist collaborative relationships.

BACKGROUND: A theoretical model of physician/pharmacist collaborative relationships, driven by 3 groups of relationship characteristics termed participant, context, and exchange, has been developed. There are no studies that have examined the types of characteristics which most influence development of collaborative relationships between physicians and pharmacists. OBJECTIVE: To test the model and determine which drivers most influence physician/pharmacist collaboration. METHODS: Data on the relationship drivers and collaborative practice were collected via a mailed survey of a random sample of 1000 primary care physicians in Iowa. Participant variables include demographics; context drivers refer to the practice environment and professional interactions between physicians and pharmacists. Exchange characteristics describe the nature of social exchange and were elicited using scores from 3 domains (relationship initiation, trustworthiness, role specification) of the Physician/Pharmacist Collaboration Instrument (PPCI). Five additional questions asked about the physician's collaborative practice with a pharmacist. Hierarchical linear regression analysis was performed with collaborative practice as the dependent variable and measures of participant, context, and exchange drivers as independent variables. RESULTS: Three hundred forty usable surveys (34%) were returned. Almost 70% of the respondents were male and aged 45.8 +/- 9.9 years (mean +/- SD). The majority were family practice physicians (72.1%) in private practice (67.3%). Regression analyses produced an R2 = 0.804 (p < 0.001). Significant predictors in the model were internal medicine physicians, professional interaction with a pharmacist, and the 3 domains of exchange drivers from the PPCI (p < 0.05). CONCLUSIONS: Although participant and context factors influenced physician/pharmacist collaborative relationships, exchange characteristics were the most influential relationship drivers. Role specification, trustworthiness, and relationship initiation were positively associated with physician/pharmacist collaborative practice. Recognition of these drivers may help pharmacists who are developing collaborative working relationships with physicians. But, studies are needed to delineate other factors that may influence physician/pharmacist relationships.

Drug-related problems and quality of life in arthritis and low back pain sufferers.

OBJECTIVE: The objective of this study was to determine the relationship between drug-related problems (DRPs) and health-related quality-of-life (HRQoL) in ambulatory, community-dwelling patients with musculoskeletal disorders. METHODS: A 12-month, prospective, observational study was conducted in 12 independent community pharmacies in eastern Iowa. Ambulatory patients with self-reported diagnoses of osteoarthritis, rheumatoid arthritis, or low back pain were invited to participate. During quarterly visits to the pharmacy, patients used touch-screen computers to fill out the Short Form-36 (SF-36) general health survey. Using the results of these point-of-service health status assessments, community pharmacists interviewed patients to assess for DRPs. To examine the influences of different DRP characteristics on HRQoL and controlling for potential confounders, both univariate and multivariate analyses were performed using the change in physical component summary (PCS) score and mental component summary (MCS) score of the SF-36 from baseline to 12 months as the dependent variables. In each regression, the independent variables were those significant variables from the univariate analyses, as well as the types of DRPs and their outcomes. RESULTS: A total of 461 patients were enrolled in the study. Through 12 months, 926 cumulative DRPs were identified. Overall regression models were significant for the PCS and MCS scores, respectively. Two types of DRPs showed significant negative associations with change in PCS: wrong drug and needs additional drug therapy. One type of DRP showed significant negative association with change in MCS: needs additional drug therapy. Resolution or improvement in DRPs showed a significant positive correlation with change in MCS but not PCS. CONCLUSIONS: Two DRPs, needs additional drug therapy and wrong drug, are associated with reduced self-reported physical health in arthritis and low back pain, while the DRP needs additional drug therapy is also associated with reduced self-reported mental health. Resolution of DRPs is associated with improvement in mental health in this cohort.

Development and initial validation of an instrument to measure physician-pharmacist collaboration from the physician perspective.

OBJECTIVE: Using a conceptual model of collaborative working relationships between pharmacists and physicians, a measure for physician-pharmacist collaboration from the physician perspective was developed. The measure was analyzed for its factor structure, internal consistency, construct validity, and other psychometric properties. METHODS: An initial 27-item Physician-Pharmacist Collaboration Instrument (PPCI) was developed to assess seven themes about professional relationships using Likert scales. The PPCI was mailed to a random sample of 1000 primary care physicians. Principal component analysis was used to assess the structure and uncover underlying dimensions of the initial instrument. Items were evaluated for inclusion or exclusion into a refined instrument. Internal consistency was assessed by calculating Alpha coefficients for each identified factor. Convergent validity was assessed using Spearman correlations between the identified factors and a previous measure of collaborative care. After measure refinement, confirmatory factor analysis was used to evaluate the fit of both versions of the instrument. RESULTS: Three hundred forty usable surveys were returned for a response rate of 34%. Almost 70% of the respondents were male with a mean age of 45.8. A majority were family practice physicians (72.1%) in private practice (67.3%). Three unique factors were identified during principal component analysis and utilized in a confirmatory factor analysis. Both a full and a 14-item reduced model were constructed and tested. Cronbach's alpha for the three factors of the full model ranged from 0.91 to 0.97, while the reliability for the reduced model ranged from 0.86 to 0.96. Comparative fit indexes of 0.97 and 0.98 were obtained, indicating good fit for the models. CONCLUSIONS: The results indicate good reliability and validity of the refined (14-item) PPCI. This instrument can be useful as a research tool for assessment of the physicians' perspective about a physician-pharmacist relationship. Further research is warranted to examine if the extent of relationship development, as measured with the PPCI, can affect patient care outcomes.

An evaluation of managing and educating patients on the risk of glucocorticoid-induced osteoporosis.

OBJECTIVE: To assess the impact of risk management activities on patient risk of glucocorticoid-induced osteoporosis. METHODS: Ninety-six adult patients taking chronic glucocorticoid therapy in 15 community pharmacies. Patients in the control group received usual and customary care. Patients in the treatment pharmacies received education and an educational pamphlet about the risks of glucocorticoid-induced osteoporosis. In addition, the treatment group pharmacists monitored the patients' drug therapy, to identify and address drug-related problems. Data including the glucocorticoid taken by the patient, medications, and osteoporosis risk factors were collected at baseline and after 9 months of monitoring, via Web-based survey completed in the pharmacy. Using an intent to treat approach, the pre-post frequency changes were compared with contrasts for presence of bisphosphonate therapy, presence of estrogen therapy, presence of calcium supplement, discussion of glucocorticoid-induced osteoporosis risk, discussion of bone density test, presence of bone mineral density test, reported inactivity, and reported low calcium diet. RESULTS: The contrast was significant in favor of the treatment pharmacies for the frequency of patients taking a calcium supplement (Control [-6.9%] vs. Treatment [17.1%], P < 0.05). No other contrast was significant. CONCLUSIONS: Community pharmacists are capable of increasing calcium supplementation among patients at risk for glucocorticoid-induced osteoporosis. Pharmacists who educate at-risk patients can impact the self-care of these patients.

Community pharmacists' work activities in the United States during 2000.

OBJECTIVES: To describe community pharmacists' work activities in the United States during 2000 and to investigate the effects of position, pharmacy type, and prescription volume on work activities. DESIGN: Cross-sectional descriptive survey of a systematic sample of 4,895 U.S. pharmacists, of which 2,250 responded. SETTING: United States. PARTICIPANTS: A sample of 832 community pharmacists working full-time (at least 30 hours per week) out of the total of 2,250 who responded to the survey. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Workload (hours worked and proportion of prescriptions dispensed at the site with which the pharmacist was personally involved) and professional responsibilities (proportion of time spent in medication dispensing, consultation, business management, and drug use management). RESULTS: As of 2000, the typical community pharmacist in the United States devoted 56% of his or her time to medication dispensing responsibilities, 19% to consultation responsibilities, 16% to business management responsibilities, and 9% to drug use management responsibilities. These results were consistent for pharmacists regardless of pharmacy type or prescription volume; however, position did significantly affect the proportion of time spent in the various activities. CONCLUSION: Pharmacists are still devoting the majority of their time to medication dispensing responsibilities. However, our findings also show that pharmacists would prefer to devote more of their time to professional responsibilities, such as consultation and drug use management, and less time to medication dispensing and business management.

Third party bargaining and contract terms: a link over time?

OBJECTIVE: To evaluate whether prior pharmacy bargaining process strategies and pharmacy dependence on third parties affect the bargaining power of pharmacies in price negotiations with third parties. DESIGN: One-time survey. SETTING: Random sample of 900 independent and small chain pharmacies in nine states: Colorado, Connecticut, Georgia, Kentucky, Minnesota, Oklahoma, Oregon, Pennsylvania, and Wisconsin. PARTICIPANTS: Two hundred sixteen of the returned surveys contained sufficient responses for this analysis. INTERVENTIONS: Survey data on pharmacy bargaining power and prior pharmacy bargaining strategies, pharmacy dependence, and market characteristics were analyzed using multiple regression in a previously developed and modified provider/third party bargaining model. MAIN OUTCOME MEASURE: Pharmacy bargaining power. RESULTS: Pharmacy bargaining power varied across our sample. Pharmacy bargaining power was positively related to whether a pharmacy previously bargained with the third parties, negatively related to prior requests for contract changes, and negatively related to the pharmacy's dependence on third parties in total. CONCLUSION: Pharmacy bargaining power is related to the bargaining strategies employed by pharmacies during the previous year and the dependence of pharmacies on third party payers in total. With the prevalence of "take-it-or-leave-it" contracts from third parties, prior pharmacy bargaining behavior may affect the initial terms of the contracts that pharmacies are offered.

Iowa medicare beneficiaries' satisfaction and experiences with a prescription drug discount card and preferred drug list.

OBJECTIVE: To evaluate the expectations, experiences, and satisfaction with the Iowa Priority Prescription Savings (IPPS) program. DESIGN: Longitudinal descriptive study. SETTING: Iowa. PARTICIPANTS: Randomly selected Iowa Medicare beneficiaries who self-enrolled in the IPPS prescription discount card program. INTERVENTIONS: Three self-administered surveys mailed in November 2002, June 2003, and September 2004, during the first, second, and third years of IPPS operation. MAIN OUTCOME MEASURES: Expectations of drug discounts, amount of discounts received, awareness of the IPPS preferred drug list (PDL), and satisfaction with the program. RESULTS: Usable response rates for the three surveys were 43.5%, 31.0%, and 38.4%. About one fourth of members initially expected discounts of more than 20% on their prescription medications. After IPPS was implemented, many members were unaware of the discounts they were receiving, but the percentage of members reporting discounts of more than $20 per month increased from 7.4% in year 1 to 16.4% in year 3. More than one half of the members were unaware of which drugs were on the PDL in years 1 and 2, but this improved to 21% unawareness in year 3. Satisfaction with the program was low but improved over time. Members who received discounts, did not expect large discounts, or received a medication review were more satisfied with the program. CONCLUSION: Some IPPS members had unrealistic expectations about the amount of discounts they would receive, and expectations of large discounts decreased satisfaction. Satisfaction and amount of discounts improved over time, and beneficiaries whose medications were reviewed, usually by a pharmacist, were more satisfied with the program. PDL awareness was a problem despite substantial educational efforts by IPPS, a finding that has implications for the recently implemented Medicare Part D drug benefit.

Drug therapy management: an empirical report of drug therapy problems, pharmacists' interventions, and results of pharmacists' actions.

OBJECTIVES: To determine the number and types of drug therapy problems identified by pharmacists at six community pharmacies, identify the interventions made by these pharmacists in their attempts to resolve drug therapy problems, and determine the results of the pharmacists' actions taken to resolve drug therapy problems. DESIGN: Retrospective review of patient records from pharmacies. SETTING: Six community pharmacies that had participated in Project ImPACT: Hyperlipidemia. PATIENTS: One hundred sixteen patients from Project ImPACT: Hyperlipidemia. INTERVENTION: Drug therapy problems, pharmacists' interventions, and results of pharmacists' actions were identified and categorized. Drug therapy problems were classified into seven categories, pharmacists' interventions into six categories, and results were categorized into eight types. Frequencies and descriptive statistics were calculated for the measures. RESULTS: A total of 512 initial drug therapy problems were reported for 116 patients in the 6 pharmacies. In addition to the initial interventions, pharmacists documented another 545 times in which they intervened on the original problems. There were 354 (69.1%) drug therapy problems associated with hyperlipidemia and 158 (30.9%) with other conditions. Overall, most common types of drug therapy problems were needs additional therapy (39.8%) and nonadherence to therapy (31.1%). The most common discretionary pharmacist interventions were patient education and physician communication, which occurred on average 4.63 and 3.30 times during the project period. The most common consequence of a pharmacist intervention was an increase in patient adherence, which was reported for almost half of the patients. CONCLUSION: Drug therapy management (DTM) for patients with dyslipidemias identified frequent drug therapy problems associated with both hyperlipidemia and other conditions. Pharmacists used interventions that included laboratory testing, patient monitoring, patient education, and physician communication to influence patient adherence and optimize drug therapy. Although further research is needed, the findings of this analysis are promising for the more widespread adoption of a DTM role by community pharmacists.
