Why do not patients receive influenza vaccine in December and January?

BACKGROUND: Influenza vaccination levels in older patients have changed little since the mid-1990s. Despite frequent health care visits by a majority of older persons, many missed opportunities continue to occur. METHODS: Patients were eligible for the study if they were age 50 and older, had not received influenza vaccine during the current season and were making a scheduled visit to one of the 13 study sites in California, New York, or New Mexico for purposes other than vaccination. Through direct observation, we determined if office staff inquired about vaccination status, discussed vaccination, or both. We defined missed opportunities as failure to administer influenza vaccine to patients for whom it was indicated. RESULTS: Missed opportunities increased steadily from October to January (P < 0.0001), and were more common when there was no inquiry or discussion (P < 0.00001), among patients aged 50-64 (P < 0.0001) and in California and New Mexico (P = 0.001). A classification tree analysis revealed that lack of inquiry and week of visit contributed most to missed opportunities. DISCUSSION: Early in the vaccination season, missed opportunities were uncommon and specific inquiries into or discussion of vaccination did not appear necessary. In December and January, patients tended to be vaccinated only when vaccination was addressed during the visit. Efforts to remind patients about vaccination later in the vaccination season may be essential to achieving higher coverage in the U.S.

Cognitive and adaptive outcome in low-grade pediatric cerebellar astrocytomas: evidence of diminished cognitive and adaptive functioning in National Collaborative Research Studies (CCG 9891/POG 9130).

PURPOSE: Clinicians often assume that children with posterior fossa tumors are at minimal risk for cognitive or adaptive deficits if they do not undergo cranial irradiation. However, small case series have called that assumption into question, and have also suggested that nonirradiated cerebellar tumors can cause location-specific cognitive and adaptive impairment. This study (1) assessed whether resected but not irradiated pediatric cerebellar tumors are associated with cognitive and adaptive functioning deficits, and (2) examined the effect of tumor location and medical complications on cognitive and adaptive functioning. PATIENTS AND METHODS: The sample was composed of 103 children aged 3 to 18 years with low-grade cerebellar astrocytomas, who underwent only surgical treatment as part of Children's Cancer Group protocol 9891 or Pediatric Oncology Group protocol 9130. The sample was divided into three groups based on primary tumor location: vermis, left hemisphere, or right hemisphere. Data were collected prospectively on intelligence, academic achievement, adaptive skills, behavioral functioning, and pre-, peri-, and postsurgical medical complications. RESULTS: The sample as a whole displayed an elevated risk for cognitive and adaptive impairment that was not associated consistently with medical complications. Within this group of children with cerebellar tumors, tumor location had little effect on cognitive, adaptive, or medical outcome. CONCLUSION: We did not replicate previous findings of location-specific effects on cognitive or adaptive outcome. However, the elevated risk of deficits in this population runs contrary to clinical lore, and suggests that clinicians should attend to the functional outcomes of children who undergo only surgical treatment for cerebellar tumors.

Estimating medical practice expenses from administering adult influenza vaccinations.

Potential business losses incurred vaccinating adults against influenza have not been defined because of a lack of estimates for medical practice costs incurred delivering vaccines. We collected data on vaccination labor time and other associated expenses. We modeled estimates of per-vaccination medical practice business costs associated with delivering adult influenza vaccine in different sized practices. Per-shot costs ranged from USD 13.87 to USD 46.27 (2001 dollars). When compared with average Medicare payments of USD 11.71, per-shot losses ranged from US$ 2.16 to USD 34.56. More research is needed to determine less expensive delivery settings and/or whether third-party payers need to make higher payments for adult vaccinations.

The price of prevention. cost of recommended activities to improve immunizations.

PURPOSE: To calculate the cost structure of a suite of immunization improvement interventions recommended by the Centers for Disease Control and Prevention (CDC). METHODS: A determination was made of the cost to clinics and agencies that implement a suite of CDC-recommended practice improvement interventions to fully immunize a child for diphtheria-tetanus-attenuated pertussis (DTaP), inactivated poliovirus (IPV), and measles-mumps-rubella (MMR) vaccines. Patient data were collected through chart analysis of 16-month-old children in clinics participating in this study's interventions between May 1997 and August 2000. The study began on October 1, 1996, and was funded for 5 years (until September 30, 2002). RESULTS: Study calculations suggest that an additional $0.013/per patient per month would be needed to cover these activities. CONCLUSIONS: Identifiable cost structures are associated with the practice improvement strategies recommended by the CDC. The method of implementation may be as important as the interventions themselves. Present compensation for immunization may not actually cover the cost of service provision, and it is unlikely to cover the costs of practice improvement, as described in this paper.

Operational conditions affecting the vaccination of older adults.

BACKGROUND: The content and context of the process of vaccinating older adults against influenza in outpatient settings has not been adequately described. Failure to appreciate the causal antecedents or precursors to the act of provider recommendation may explain why so many efficacious interventions identified by the U.S. Task Force on Community Preventive Services fail to be routinely implemented and why influenza immunization rates have remained static over the past decade. METHODS: This study used critical path analysis from data collected during standardized workflow observations of patients more than 50 years of age from a convenience sample of 16 ambulatory care settings in San Diego, California; Rochester, New York; and Albuquerque, New Mexico. Observations were made from October 23, 2001 to January 31, 2002. RESULTS: In this study, 62% (151/243) of patients observed during scheduled extended visits received influenza vaccinations. When operational, temporal, and clinical factors are examined altogether through critical path analysis, a model of seven critical organizational support, temporal, and clinical activities emerges that is able to predict 93% of the immunizations. Variation from the model predicts 73% of the missed opportunities. CONCLUSIONS: Vaccination of adults should not be seen as simply an incremental activity added to the general health encounter. Assuring a high rate of vaccination requires adequate time and operational support. Provider-patient discussion is more productively viewed as the culmination of the immunization process, not the beginning. Finally, this study indicates the potential need to identify and compare processes of care associated with other specific preventive services.

The forms that bind: multiple data forms result in internal disaggregation of immunization information.

To examine how forms encountered during routine clinical activities impact a provider's immunization activity, workflow analysis was performed in nine community clinics and small private practices. Data gathered included the number, source, and nature of forms. A total of 200 forms were used by the nine clinics just for children under 35 months of age. These represent a real labor cost as well as an opportunity cost. Use of a single summary sheet, yearly review of the forms, and coordination of agency documentation efforts are recommended.

Status of quality improvement activities to improve immunization practices and delivery: findings from the immunization quality improvement symposium, October 2003.

The Centers for Disease Control and Prevention convened a symposium on 22-23 October 2003 to bring together investigators and stakeholders working to apply the quality improvement (QI) approaches to immunization delivery in individual medical practices. The goal was to identify effective program components and further development of model programs. A call for projects was widely disseminated; of 61 submissions received, eight projects were selected. Three of the eight programs used the "train the trainer" approach, three used site-specific training, one used a "practice collaborative" approach, and one employed the use of tracking and outreach workers to effect change. At the symposium, invited experts reviewed each program. Common program features that appeared effective included involvement of a variety of staff within the office environment, collection and review of site-specific performance measurements to identify gaps in delivery, periodic monitoring of performance measurement to revise interventions and maintain the improvements, and provision of formal continuing education credits. While research is needed on ways to promote and integrate QI into practices, it is likely that a variety of QI strategies will be shown to be effective, depending on the clinical settings. The field will benefit from standardized outcome measures, cost analysis, and evaluation, so comparisons can be made among different programs.

Non-punctual patients: planning for variability in appointment arrival times.

Tighter competition and rationed resources place a premium on health clinic management of patient arrival times to maximize smooth workflow dynamics and consistency in patient processes. Early efforts to analyze patient arrival characteristics relied on assumptions that may have been too simplistic. For instance, it was assumed that a scheduled patient's arrival was likely to fit a bell-shaped curve in terms of being early, late, or on time and that any one patient's likelihood of being "on time" was purely a random event. However, our analysis of patient arrival times, obtained from detailed workflow observations in nine community clinics, indicates that the likelihood of a patient arriving early, late, or on time is neither entirely random nor does the pattern of arrivals fit a bell-shaped curve. Rather, patients tend to arrive in "clumps," possibly due to factors such as traffic patterns and parking availability. These findings are important with respect to 1) clinic practice management, 2) scheduling optimization strategies, and 3) computer simulation and analysis of clinic processes.

Can the doctor still see me? What happens when patients arrive late?

Demands to optimize productivity and quality require a patient scheduling system that can balance patient demand and clinic resources. The consequences of unscheduled and late patient arrivals on operational efficiencies have been documented. Less understood is the impact of unscheduled and late arrivals on the quality of service each receives. This article examines the impact of unscheduled and late patient arrivals on operational, clinical and administrative outcomes that affect quality of care of children potentially eligible for immunizations. An unexpected finding was the generally better and faster levels of service for late arrivals.

The (mis)application of management science in medicine: a flawed concept.

The business of medicine once again finds itself in the throes of rapidly escalating costs, concerns about quality of care, and demands for efficiency while simultaneously enhancing quality. Considerable effort has already been spent in trying to improve costs, quality, and patient satisfaction. The apparent failure to do so may be the result of a fundamental misunderstanding of the salient features of clinical practice and the misapplication of quality improvement techniques. This article explores some of the significant issues and offers potential new directions.

Mass vaccination clinics versus appointments.

Influenza vaccine is a safe, effective, and cost-effective intervention that can prevent serious disease in adults. Opinions differ as to the most effective method for delivering the vaccine to the greatest number of high-risk adults. The objective of this article is to compare immunization delivery of influenza vaccine to high-risk adults during two types of clinic visits: routine scheduled appointments versus mass clinics. Data was collected at 15 ambulatory care settings on 599 patients 50 years and over from October 23, 2001, to January 31, 2002. Immunizations given at either routine scheduled visits or at mass influenza immunization clinics were compared for costs and resource requirements (productivity), and completeness of delivery of quality visit components (efficiency). The two visit types presented significantly different strengths on key clinical functions. Routine scheduled appointments promoted more review of patient health history and more of the contact information necessary for reminder/recall and audit functions. In mass immunization clinics, patients were more likely to be vaccinated, with far less time spent in either direct services or in waiting, and it was more likely that the required vaccination information statements (VIS) would be provided. Mass vaccination clinics and routine scheduled appointments are both viable service strategies for delivering influenza vaccines. This study suggests the greatest advantage occurs when both strategies are used in a coordinated manner.
