Adverse events among nursing home residents with Alzheimer's disease and psychosis.

PURPOSE: The objective of this study was to quantify rates of adverse events in a high-risk multi-morbid population of institutionalized patients with Alzheimer's disease (AD). METHODS: We conducted a retrospective cohort study among nursing home residents diagnosed with AD and psychosis during January 1998 to October 1999. Using the Medicare Minimum Data Set (MDS) and Medicare inpatient claims (ICD-9 codes), 7728 nursing home residents aged 55-95 years with AD and psychosis were identified for study. Potential adverse events of interest were identified from the MDS and Medicare inpatient claims (ICD-9 codes). We estimated the incidence rate (IR) and 95% confidence interval (CI) for each adverse event during a 2-year follow-up period. RESULTS: Of the 7728 residents studied, nearly 30% were considered 'dependent' by the activities of daily living (ADL) score and approximately 15% exhibited severe cognitive impairment at baseline. At least 90% had comorbid psychiatric disorders. The most common adverse event was accidental injury, occurring at a rate of 97.7 per 100 person-years (95%CI = 94.7-100.7). Other common adverse events were death (IR = 44.6/100 person-years; 95%CI = 42.9-46.4), infection (IR = 41.8/100 person-years; 95%CI = 39.7-43.8), pain (IR = 43.5/100 person-years; 95%CI = 41.2-45.9), anorexia (41.3/100 person-years; 95%CI = 39.1-43.6), and weight change (IR = 40.2/100 person-years; 95%CI = 38.7-41.7). CONCLUSIONS: This information on the occurrence of adverse outcomes among nursing home patients with AD and psychosis provides useful context for any safety event observed among patients treated for psychosis.

Differential associations of beta-blockers with hemorrhagic events for chronic heart failure patients on warfarin.

PURPOSE: Beta-blockers have many different physiologic effects that could potentially influence the risk of hemorrhagic events in chronic heart failure patients (CHF) on warfarin. We examined how different beta-blockers vary in their associated risk of a hemorrhagic event. METHODS: We used databases from the Department of Veterans Affairs (VA) that contain information on medications prescribed, diagnoses, and hospitalizations. We identified patients with CHF on warfarin and either metoprolol, carvedilol, atenolol, or no beta-blocker during 1999-2001. We modeled time to first hemorrhagic event using a Cox proportional hazards model, adjusting for age, ethnicity, comorbidities, and other factors. INR levels were examined in a subsample of 3546 patients. RESULTS: We identified 66,988 CHF patients on warfarin. Hemorrhagic events occurred in 15.3% of the sample and, in 3.8% of the sample, the hemorrhage was considered severe. Compared to patients on carvedilol, the hazards ratio for a new hemorrhagic event was 1.25 (1.17, 1.34) for no beta-blocker, 1.27 (1.18, 1.38) for atenolol, and 1.38 (1.28, 1.48) for metoprolol. No differences in INR levels were evident among the four groups. CONCLUSIONS: The risk for a hemorrhagic event among CHF patients on warfarin may be affected by beta-blocker use and varies depending on which beta-blocker is prescribed.

Use of cyclo-oxygenase 2 inhibitors (COX-2) and prescription non-steroidal anti-inflammatory drugs (NSAIDS) in UK and USA populations. Implications for COX-2 cardiovascular profile.

BACKGROUND: COX-2 and NSAIDS differ in their gastrointestinal (GI) and cardiovascular (CV) toxicity from pharmacological, clinical and epidemiologic point of views. OBJECTIVE: Describe the patterns of use of NSAIDS and COX-2 in The Health Improvement Network (THIN) database in UK and the PharMetrics database in USA. METHODS: We examined the experience of 10 distinct cohorts of new users of diclofenac, naproxen, ibuprofen, piroxicam, other NSAIDS, meloxicam, celecoxib, etoricoxib, rofecoxib and valdecoxib. The study period was 1 January 1995 through 2004 (31 March in UK and 28 February in USA). We collected information on covariates including history of upper GI disease, CV disease, hepatic disease, dosage, concomitant medication, and visits to a rheumatologist. RESULTS: We identified 486 076 unique patient-drug pairs in UK and 1 533 239 in USA. In UK population 78 201 (16%) were COX-2 users and in PharMetrics 324 206 (21%) were COX-2 users. Diclofenac and ibuprofen (NSAIDS), and celecoxib and rofecoxib (COX-2) were the agents prescribed most frequently. The duration of therapy was longer among celecoxib and rofecoxib users than among other users. More COX-2 users than NSAIDS users received concomitant gastroprotective agents (GPA), corticosteroids and anti-platelet therapy, and had a history of thromboembolic events and hypertension. PharMetrics patients were prescribed higher doses of NSAIDS and COX-2. The use of any single agent for more than 90 days was uncommon, but more frequent in PharMetrics. Switching was uncommon and was generally to a NSAID. DISCUSSION: Our results confirm some previous findings from other authors such as the presence of both GI and CV channelling to COX-2 agents but refute others, such as the frequency of drug switching between these agents. The typical use of COX-2 agents in practice is for shorter duration, and at lower doses, than was employed in randomized clinical trials. This difference may help clarify the apparent discrepancy with respect to CV toxicity between the results from clinical trials, which showed a higher CV risk with these drugs, and non-experimental epidemiologic studies, which showed lower or no increase in risk.

Psychosocial mediators of a nurse intervention to increase skin self-examination in patients at high risk for melanoma.

This prospective study examines psychosocial mediators of an efficacious skin self-examination (SSE) intervention that includes provision of a whole-body digital photography book depicting the entire skin surface. Individuals (n = 100) with established risk factors for melanoma were recruited from the Memorial Sloan-Kettering Cancer Center Pigmented Lesion Clinic during their initial dermatologist visit and were randomized to receive a photobook immediately (n = 49) or 4 months after intervention delivery (n = 51). Potential mediators included self-efficacy and response efficacy drawn from Social Cognitive Theory, melanoma worry, and SSE anxiety drawn from Self-Regulation Theory, and skin cancer knowledge, and skin awareness. Only self-efficacy was a significant mediator, accounting for 8% of the total effect of photobook enhancement on SSE adherence at 4 months.

Variation in the diagnosis, treatment, and management of melanoma in situ: a survey of US dermatologists.

OBJECTIVE: To assess current practices of US dermatologists regarding the diagnosis, treatment, and management of melanoma in situ (MIS). DESIGN: Survey. PARTICIPANTS: A total of 1200 dermatologists randomly selected from the American Board of Medical Specialists Directory of Board Certified Medical Specialists. MAIN OUTCOME MEASURES: Results based on 597 questionnaires returned. RESULTS: The overall response rate was 63% (597 of 945 eligible participants). To aid in clinical assessment, respondents reported using a magnifying lens (57.4%) and dermoscopy (17.4%). Most dermatologists preferred excisional and saucerization biopsies as the method of choice for sampling. A large percentage of physicians (78.9%) preferentially used dermatopathologists for the evaluation of the majority of pigmented lesions. Although most respondents would not unquestioningly accept a benign pathology diagnosis when there was a clinical suspicion of MIS, 16.1% would accept a pathologist's diagnosis without further action. There was no consensus on the appropriate surgical margins or depth of excision for MIS. Of the respondents who characterized MIS as premalignant and malignant, 63.2% and 46.4%, respectively, did not know what percentage of MISs would progress to metastatic disease if left untreated. CONCLUSIONS: Considerable variability exists in the clinical concept and management of MIS. Dermoscopy is underutilized. The true nature of the evolution of MIS is unknown. Surgical margins and depth of excision need to be standardized to help dermatologists manage disease. Further research in the specific area of MIS is warranted to develop clear guidelines in the management and prevention of further disease.

Student-parent agreement in self-reported sun behaviors.

OBJECTIVE: We sought to describe agreement between parent proxy and student self-reported sun behaviors and sun protective practices in adolescents aged 10 to 14 years. METHODS: We conducted a cross-sectional pilot study of students (n = 52) from two classrooms, grades 6 and 7, at a school system in Framingham, Mass. Data were collected using self-administered questionnaires. Students were asked to report their sun behaviors and sun protective practices. Proxy measures were obtained by asking parents to report sun behaviors and practices of their children. Agreement was measured using weighted kappa analysis for ordinal data. Mean differences (95% confidence intervals) were calculated. RESULTS: The response rate for student/proxy pairs was 96% (n = 50). Agreement between student and proxy was good for skin color, sunscreen use, number of sunburns in the past summer, and application of sunscreen while in other outdoor places (range kappa = 0.52-0.73). Lowest agreement was found for questions relating to wearing a shirt, wearing a hat, sitting in the shade, and frequency of parental sunscreen application to the students' backs (range kappa = 0.08-0.28). Mean differences in responses between student and proxy respondents were relatively small ranging from -0.39 to +0.25. CONCLUSIONS: The lack of a gold standard in the assessment of sun exposure and related sun protective practices limits the ability to validate these exposure measures in skin cancer studies. The assessment of sun exposure behaviors is especially problematic when relying on a child's ability to accurately recall these exposures. Parent proxy measures are often used as surrogate measures and for validation purposes. We found low to moderate student/proxy agreement in this pilot study suggesting that adolescents can effectively recall their recent sun behaviors and protective practices when compared with parent proxy measures.

Hypertension knowledge, awareness, and attitudes in a hypertensive population.

OBJECTIVE: Improved recognition of the importance of systolic blood pressure (SBP) has been identified as one of the major public health and medical challenges in the prevention and treatment of hypertension (HTN). SBP is a strong independent risk factor for cardiovascular disease but no information is available on whether patients understand the importance of their SBP level. The purpose of this study was to assess HTN knowledge, awareness, and attitudes, especially related to SBP in a hypertensive population. DESIGN/SETTING/PATIENTS: We identified patients with HTN (N=2,264) in the primary care setting of a large midwestern health system using automated claims data (International Classification of Diseases, Ninth Revision [ICD-9] codes 401.0-401.9). We randomly selected 1,250 patients and, after excluding ineligible patients, report the results on 826 completed patient telephone interviews (72% response rate [826/1,151]). MAIN RESULTS: Ninety percent of hypertensive patients knew that lowering blood pressure (BP) would improve health and 91% reported that a health care provider had told them that they have HTN or high BP. However, 41% of patients did not know their BP level. Eighty-two percent of all patients correctly identified the meaning of HTN as "high blood pressure." Thirty-four percent of patients correctly identified SBP as the "top" number of their reading; 32% correctly identified diastolic blood pressure (DBP) as the "bottom" number; and, overall, only 30% of patients were able to correctly identify both systolic and diastolic BP measures. Twenty-seven percent of patients with elevated SBP and DBP (as indicated by their medical records) perceived that their BP was high. Twenty-four percent of patients did not know the optimal level for either SBP or DBP. When asked whether the DBP or SBP level was more important in the control and prevention of disease, 41% reported DBP, 13% reported SBP, 30% reported that both were important, and 17% did not know. CONCLUSIONS: These results suggest that, although general knowledge and awareness of HTN is adequate, patients do not have a comprehensive understanding of this condition. For instance, patients do not recognize the importance of elevated SBP levels or the current status of their BP control. An opportunity exists to focus patient education programs and interventions on the cardiovascular risk associated with uncontrolled HTN, particularly elevated SBP levels.

Patient experiences with photo books in monthly skin self-examinations.

Patients with multiple nevi are at greater risk for developing melanoma but may be unable to assess their skin accurately without an effective tool. At Memorial Sloan-Kettering Cancer Center, the standard of practice has been to use a patient educational brochure teaching high-risk patients mole mapping, a procedure of recording moles by drawing them. The photo print book offers patients an improved way of peforming skin self-examination (SSE) in comparison to drawing. The purpose of this study was to determine patient experiences through patient interview and to learn ways to increase patient compliance and understanding of monthly SSE performance using a photo book.

Diagnostic accuracy of patients in performing skin self-examination and the impact of photography.

OBJECTIVE: To determine the sensitivity and specificity of skin self-examination (SSE) to detect new and changing moles with and without the aid of baseline digital photographs in patients with dysplastic nevi. DESIGN AND INTERVENTION: Patients had baseline digital photography and mole counts of their back, chest, and abdomen and were instructed to perform a baseline SSE. Print copies of the images were provided to the patient. Following the baseline examination, the appearance of existing moles was altered and new moles were created using cosmetic eyeliner. The number of moles altered and/or created totaled approximately 10% of each patients' absolute mole count. SETTING AND PATIENTS: Fifty patients with 5 or more dysplastic nevi from the outpatient clinic at Memorial Sloan-Kettering Cancer Center, New York, NY. MAIN OUTCOME MEASURE: Skin self-examinations with and without access to the baseline photographs to identify the number of new and altered moles. RESULTS: The sensitivity and specificity of SSE for detection of both altered and new moles without photography were 60.2% and 96.2%, respectively. Skin self-examination with photography yielded a sensitivity and specificity of 72.4% and 98.4%, respectively. The findings were similar when stratified by site (back vs chest or abdomen). The sensitivity and specificity for new moles were higher compared with altered moles. CONCLUSIONS: Access to baseline photography improved the diagnostic accuracy of SSE on the back and chest or abdomen and improved detection of changing and new moles. Our results suggest that baseline digital photography in tandem with SSE may be effective in improving the diagnostic accuracy of patients performing SSE.

The Framingham school nevus study: a pilot study.

OBJECTIVES: To (1). describe nevus patterns using digital photography and dermoscopy; (2). evaluate the relationship between host and environmental factors and prevalence of nevi in schoolchildren; and (3). demonstrate the feasibility of conducting a longitudinal study. DESIGN: Cross-sectional survey and 1-year prospective follow-up study. PARTICIPANTS: Students from 2 classrooms, grades 6 and 7, in the Framingham, Mass, school system (N = 52). MAIN OUTCOME MEASURES: A survey was completed by students and 1 of their parents that included questions on demographic and phenotypic characteristics, family history of skin cancer, and sun exposure and protection practices. An examination of nevi on the back was performed that included digital photography and digital dermoscopy. Follow-up child and parent surveys and examinations were conducted at 1-year follow-up. RESULTS: At baseline, the median number of back nevi was 15 (mean [SD], 21.9 [15.3]). Older age, male sex, fair skin, belief that a tan is healthier, tendency to burn, and sporadic use of sunscreen were positively associated with mole count, although age was the only statistically significant factor. Predominant dermoscopic patterns for the index nevus were as follows: 38% globular, 14% reticulated, 38% structureless, and 10% combinations of the above patterns with no predominant characteristic. The overall participation rate from baseline to follow-up was 81% (42/52) for the skin examination process. At the 1-year follow-up examination, new nevi were identified in 36% of students (n = 15), while 9.6% of baseline index nevi had changes in the dermoscopic pattern. Dominant dermoscopic pattern was related to nevus size: smaller nevi tended to be structureless, while larger nevi were of mixed pattern. CONCLUSION: This study supports the feasibility and utility of digital photography and dermoscopy for the longitudinal study of nevus evolution in early adolescence.

Patient adherence to skin self-examination. effect of nurse intervention with photographs.

BACKGROUND: Results from a single case-control study suggest that skin self-examination (SSE) has the potential to reduce mortality from melanoma by 63%. Despite these encouraging results, SSE rates are low. Few prospective studies of interventions to increase SSE in high-risk cohorts have been performed. The purpose of this study was to assess the impact of a brief nurse-delivered intervention using digital photographs on patients' adherence to performing SSE. DESIGN SETTING/PARTICIPANTS: Patients at high risk for melanoma skin cancer (five or more dysplastic nevi) (N=100) were recruited from the outpatient Pigmented Lesion Clinic at Memorial Sloan-Kettering Cancer Center. All participants had baseline whole-body digital photography as part of their clinical evaluation. INTERVENTION: Patients were randomized: Group A (n =49) received a teaching intervention (physician and nurse education module) with a photo book (personal whole-body photographs compiled in the form of a booklet, with nurse instruction on how to use the photographs); and Group B (n =51) received the teaching intervention only without a photo book. MAIN OUTCOMES/MEASURES: Self-administered questionnaires were provided at three intervals: baseline, post-teaching intervention, and at the 4-month post-baseline visit. To assess adherence with SSE, patients were asked, "How many times in the past 4 months did you (or someone else) usually, thoroughly examine your skin?" RESULTS: In Group A (teaching intervention with photo book), 10.2% of the patients at baseline reported skin examination three or more times during the past 4 months, while 61.2% reported skin examination three or more times at the 4-month follow-up (p =0.039 for paired comparison). In Group B (teaching intervention only), nearly 20% of the patients at baseline reported skin examination three or more times during the past 4 months, while 37% reported skin examination three or more times at the 4-month follow-up (p =0.63). The increase in reported skin examination was compared between the two groups (>51% v >17.6%, p =0.001). CONCLUSIONS: The results suggest that a brief nurse-delivered intervention is effective at increasing patient adherence with SSE. Utilizing digital photographs as an adjunct to screening appeared to increase patient adherence to performing SSE.

Treatment and referral patterns for colorectal cancer.

BACKGROUND: National guidelines recommend adjuvant chemotherapy for colorectal cancer stages III, and IV; however, it has been shown that only 45-55% of these patients receive chemotherapy. OBJECTIVES: We sought to describe treatment patterns for patients diagnosed with colorectal cancer and to examine the reasons why patients do not receive chemotherapy. RESEARCH DESIGN: This was a retrospective cohort study. SETTING AND PATIENTS: Patients included newly diagnosed cases of colorectal cancer at a health maintenance organization in central Massachusetts between January 1, 1997, and June 30, 1999. MAIN OUTCOME MEASURE: The main outcome measure was a referral or visit to an oncologist. RESULTS: Sixty-six percent (n=143) of the 217 colorectal cancer cases had a referral/visit to an oncologist or evidence of chemotherapy within 4 months of the index date. The referral rates by stage were: stage I, 47.7%; stage II, 59.5%; stage III, 87.1%; and stage IV, 66.7%. Of patients not referred with stage III disease, 4/8 were not referred because the treating physician did not recommend an oncology referral; patient refusal accounted for 3/8 (37.5%). The most commonly cited reason for lack of referral for stage IV patients was existing comorbidities or death. Younger age (<70 years) and stage III at diagnosis were significant predictors of oncology referral/visit. CONCLUSIONS: A substantial proportion of colorectal cancer patients are receiving appropriate referral for chemotherapy. This study is the first to elucidate reasons why patients do not receive chemotherapy and highlights both patient and physician factors.

Skin cancer prevention and detection by nurses: attitudes, perceptions, and barriers.

BACKGROUND: To examine attitudes and perceptions of nurses with respect to skin cancer prevention and detection; to identify barriers to skin cancer prevention and detection by nurses. METHODS: Descriptive survey of 457 nurses from the Texas State Board of Nurse Examiners in 1997. RESULTS: Eighty-nine percent of the nurses reported that skin cancer was a serious problem, and 97% believed that many people were at risk. More than 89% stated that skin cancer prevention/detection would benefit patients, and 94% believed that such skills would benefit nurses. Eighty-four percent reported that it was in their scope of practice to teach skin cancer prevention to patients, and 61% stated that it was in their scope of practice to detect skin cancer in patients. Barriers to skin cancer prevention and detection included lack of national guidelines (69%), low priority among doctors (63%), and the belief that patients should take full responsibility for prevention (50%). Barriers to continuing education for skin cancer screening included lack of money (43%), not knowing how to obtain education (41%), time away from work (36%), and time away from home (26%). CONCLUSIONS: These findings may suggest that nurses can play a role in skin cancer prevention and detection.

Symptoms and signs of primary melanoma: important indicators of Breslow depth.

BACKGROUND: Operative management of patients with cutaneous melanoma is guided primarily by the pathologic determination of Breslow depth. Differentiating early from more advanced melanoma is not always straightforward and may be complicated by pathologic misdiagnosis, inappropriate biopsy techniques, or poor specimen handling. Inconsistencies between the patient's history and the pathologist's interpretation may alert the physician to the possibility of misdiagnosis. In this setting, awareness of the signs and symptoms (S/S) of thin versus intermediate or deep melanoma may be helpful in guiding management. The authors performed a prospective evaluation of the S/S reported by patients who presented at Memorial Sloan-Kettering Cancer Center with invasive primary melanoma. METHODS: The authors prospectively evaluated 369 patients with a detailed questionnaire regarding their S/S at the time of their initial visit. Multivariate logistic regression was employed to study the association between S/S reported by the patient and Breslow depth of the primary lesion, adjusting for gender, age, and anatomic site. Patients were grouped by the Breslow depth of their primary tumors into three categories for analysis: those with thin (< or = 1.0 mm), intermediate (1.0-4.0 mm), and thick (> or = 4.0 mm) lesions. RESULTS: Gender, age, and primary site were not significantly predictive of increasing category of Breslow depth. Most patients reported at least one S/S (n=278 [75%]). The most common S/S reported was an increase in size (n=187 [51%]), followed by a change in color (n=147 [40%]). Bleeding (n=95 [26%]), lump (n=86 [23%]), itching (n=83 [22%]), skin breakdown (n=66 [18%]), and pain (n=24 [7%]) were less common. In a multivariate analysis, the S/S most strongly associated with an increased category of Breslow depth was bleeding (odds ratio [OR] 7.5), followed by pain (OR 3.3), lump (OR 2.2), itching (OR 1.9), and change in size (OR 1.7). The only S/Ss not independently associated with an increasing category of Breslow depth were a change in color and skin breakdown. The presence of one or more S/S was associated significantly with an increased category of Breslow depth of the primary melanoma (1 or 2 S/S vs. no S/S: OR, 4; > or= 3 S/S vs. no S/S: OR, 24). CONCLUSION: Most S/Ss of cutaneous melanoma are associated with an increasing risk of a deep primary lesion. Understanding this relationship can be valuable in patient management, especially when pathologic data are incomplete or inconsistent with the patient's history.

Adoption of new technologies for early detection of melanoma in dermatologic practice.

The identification and diagnosis of early melanoma will reduce unnecessary operations and may be important in reducing mortality from melanoma and impacting cost savings to the health system. New technologies are being developed and used at some specialized centers to facilitate the detection and diagnosis of early melanoma for patients at high risk. These technologies include but are not limited to digital photography, dermoscopy, computerized image analysis systems, and confocal scanning laser microscopy. To most effectively implement these novel approaches, it is important to identify the key factors that influence the adoption or diffusion of new medical technologies. We propose patient-, physician-, and health care system-related factors that influence the diffusion of new technologies for the early detection of skin cancer. Studies involving physicians and patients in a variety of clinical settings need to be conducted to achieve a greater understanding of the barriers to the adoption of these new technologic tools that are intended to aid in skin cancer screening.

Physician-related barriers to the effective management of uncontrolled hypertension.

BACKGROUND: Primary care physicians may not be aggressive enough with the management of hypertension. The purpose of this study was to identify barriers to primary care physicians' willingness to increase the intensity of treatment among patients with uncontrolled hypertension. METHODS: Descriptive survey study. We sampled patient visits in a large midwestern health system to identify patients with uncontrolled hypertension. The treating primary care physicians were asked to complete a survey about the patient visit with a copy of the office notes attached to the survey (patient visits, n = 270; response rate, 86%). RESULTS: Pharmacologic therapy was initiated or changed at only 38% of visits, despite documented hypertension for at least 6 months before the patients' most recent visit. The most frequently cited reason for no initiation or change in therapy was related to the primary care physicians being satisfied with the blood pressure (BP) value (satisfactory BP response, 30%; satisfactory diastolic BP response, 16%; only borderline hypertension, 10%). At 93% of these visits, systolic BP values were 140 mm Hg or higher, which is above the cut point recommended by Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure guidelines, and 35% were 150 mm Hg or higher. On average, physicians reported that 150 mm Hg was the lowest systolic BP at which they would recommend pharmacologic treatment to patients, compared with 91 mm Hg for diastolic BP. CONCLUSIONS: Our findings suggest that an important reason why physicians do not treat hypertension more aggressively is that they are willing to accept an elevated systolic BP in their patients. This has an important impact on public health because of the positive association between systolic BP and cardiovascular disease.

Use of nonphysician health care providers for skin cancer screening in the primary care setting.

BACKGROUND: Nonphysician health care providers are in an optimal position to provide cancer prevention and screening services. METHODS: We conducted a survey of primary care physicians to determine physician use and amenability to use of nonphysician health care providers to perform skin cancer screening in comparison with other cancer screening examinations. RESULTS: A total of 1,363 eligible physicians completed the survey. Of these, 631 physicians (46%) reported a nurse practitioner or physician assistant performing at least one type of cancer screening examination on their patients. Twenty-nine and 22% of all physicians reported nurse practitioners or physician assistants performing skin cancer screening, respectively. Family physicians were more likely to use nurse practitioners and physician assistants to perform these cancer screening examinations than internists (chi(2) test, P = 0.001 for each examination). Skin examinations were performed less frequently by nurse practitioners and physician assistants than all other cancer screening examinations. A total of 73-79% of family physicians and 60-70% of internists were amenable to having a nonphysician health care provider perform one or more of these examinations. CONCLUSIONS: Primary care physicians are currently utilizing nonphysician health care providers to perform cancer screening examinations and the majority of those surveyed are amenable to the use of these providers for such examinations. This suggests that one possible strategy for increasing skin cancer screening is through an expanded role of nonphysician health care providers.
