Cost-conscious prescribing of nonsteroidal anti-inflammatory drugs for adults with arthritis. A review and suggestions.

Salicylates and nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for the treatment of painful disorders. This article reviews the efficacy, side effects, and costs of these agents and proposes a practical approach to using them in a cost-effective manner. Although there may be some differences in efficacy among available drugs, these do not appear sufficient to justify using the more expensive agents in most cases. Adverse effects, especially gastrointestinal (GI), add to the cost of using these drugs. Aspirin and all nonsalicylate NSAIDs share a risk of causing gastric ulcer, upper GI bleeding, and GI perforation. Prostaglandin inhibition by these agents may lead to reduced glomerular filtration rate and renal failure. There may be modest differences in GI and renal risks with the different agents, but these are minimal. Prophylaxis against gastric ulceration with anti-ulcer drugs has been recommended, and one agent, misoprostol, is approved for use in the United States for this purpose. Whether use of prophylaxis will increase or decrease the costs associated with NSAID therapy remains to be determined. Nonacetylated salicylates may cause less GI adverse effects and may be somewhat "renal sparing." Strategies that would reduce the cost of care for painful musculoskeletal disorders without compromising quality of care include using acetaminophen instead of an NSAID for noninflammatory disorders, trying nonacetylated salicylates as less expensive and safer alternatives to NSAIDs, using one agent at a time, allowing sufficient time to evaluate the therapeutic effect before changing agents, returning to the least expensive and/or safest drug if a trial of several in succession fails to find one that is clearly better, and reserving prophylactic use of antiulcer agents for patients who are at especially high risk and for whom anti-inflammatory effects are clearly needed.

Appropriateness of short-stay admissions for procedures in six Veterans Affairs hospitals.

Admissions records were reviewed for six acute care Veterans Affairs Medical Centers (VAMC's) in New England to determine appropriateness of short-stay admissions (two days or less) in fiscal years 1986 and 1987 for certain medical and surgical procedures. Results indicated that such admissions accounted for 18,588 (22%) of a total of 84,266 admissions for the six hospitals; of these admissions, 4,362 were for procedures commonly performed on an outpatient basis. Criteria developed by a peer review board of physicians was applied to a sample of 728 (16.7%) of the 4,362 short-stay admissions for these procedures; 190 (26.1%) admissions from this sample were found to be inappropriate. Inappropriateness rates (9.1% to 46.1%), as well as the number and type of procedures, varied among the six VAMCs. Some VAMCs may be able to improve efficiency by performing more procedures on an outpatient basis.

Quality of acute episodic care in investor-owned ambulatory health centers.

This article examines the quality of acute episodic care for five diagnostic categories amenable to one-visit diagnosis and treatment at the nation's largest chain of investor-owned ambulatory care centers. A total of 803 medical records were audited for five common conditions and measured against specific protocols. In four of the five diagnostic categories studied--pharyngitis, otitis media, vaginitis, and use of tetanus immunization--42-97% of patients received care that met or exceeded the standards set by a panel of practicing academic physicians. In follow-up of an incidental high blood pressure reading, however, study physicians met the standard only 24% of the time. Some overprescribing and overtreatment with immunizations were detected. As far as comparison is possible to other studies, results suggest that care in this setting falls within the range of experience that has been reported for other types of practices. In spite of direct economic incentives to increase volume, little evidence was found of overuse of ancillary tests or unnecessary scheduling of repeat visits.

The persistent problem of poor blood pressure control.

Despite improvements in the control of hypertension in the United States, there is evidence that considerable numbers of people still have uncontrolled high blood pressure (BP). Because mortality and morbidity are reduced in proportion to BP reduction, it is important to identify the major causes of failure to control hypertension. This article summarizes the results of various studies of BP control: population surveys, assessments of usual practice, worksite programs, large-scale special projects, and quality assurance programs. The evidence suggests that patient characteristics and behaviors explain much of the poor BP control in patients under care. The most important of these patient factors is compliance. However, other factors associated with poor BP control are excessive alcohol intake, life stress, lower income, younger age, black race, male sex, and unmarried state. In evaluating BP control, the clinician and researcher must also be aware of various measurement effects that may lead to erroneously high BP readings.

Limitations of provider interventions in hypertension quality assurance.

In an institutional quality assurance program in hypertension, performance of tests, control of blood pressure, and follow-up were monitored through a computer program that was developed to audit records in an automated record system. Two types of feedback previously shown to be effective were provided quarterly for a period of one year to experimental providers. For all hypertensives considered together, there were no differences between scores of Experimental and Control providers based on percentage of patients meeting pre-set criteria in testing--87% vs 87%--, blood pressure control--58% vs 59%--, or follow-up--79% vs 77%. Only small but significant differences occurred in the subgroup of moderate to severe hypertensives. There appear to be limitations to what can be accomplished through hypertension quality assurance interventions directed at providers of care in this institutional setting. Interventions designed to deal directly with patients whose blood pressures are uncontrolled may be more effective.

Improving physician performance through peer comparison feedback.

A project to improve physician performance in colorectal cancer screening was evaluated as part of an ambulatory quality assurance program. A minimum standard was adopted requiring a digital examination and stool test for occult blood at annual check-ups of patients aged 40 years and older. During a 31/2-year period, three different intervention strategies for improved compliance with the standard were sequentially implemented and assessed: educational meeting, retrospective feedback of group compliance rate, and retrospective feedback of individual compliance rate compared with that of peers. A pretest/posttest design was employed in evaluating the first two intervention strategies. Neither strategy resulted in significant improvement in compliance. Monthly feedback of individual performance ranked with that of peers was then implemented in a randomized clinical trial utilizing a crossover design. During the first 6-month period, the physicians receiving feedback (group 1) improved from 66.0% to 79.9% (P less than 0.001), while the control group (group 2) also improved, from 67.5% to 76.6% (P less than 0.001), suggesting a spillover effect. During the second 6-month period, group 2 received feedback and group 1 did not. Group 1 stabilized at approximately 80% while group 2 continued to improve from 76.6% to 84.0% (P less than 0.001). Behavior changes persisted at 6 and 12 months after intervention.

A computer-based monitoring system for follow-up of elevated blood pressure.

An automated surveillance system utilizing a computer-based medical record system (COSTAR) was designed to improve the follow-up of patients with newly identified elevated diastolic blood pressure. A population of patients was selected where, in the 6-month period following the initial measurement of an elevated diastolic blood pressure, there were fewer than two visits during which blood pressure was recorded. In a randomized controlled clinical trial, this poor follow-up population was divided into two groups, with computer-generated reminders being automatically generated for only patients in the experimental group. Follow-up was significantly improved in the group receiving the reminders, both in terms of rate of follow-up attempted or achieved by the responsible physician and in the repeated recording of blood pressure. We conclude that a computer-based reminder system improves follow-up of newly discovered elevation in diastolic blood pressure.

The role of patient interventions in ambulatory quality assurance programs.

This paper highlights several studies conducted by a quality assurance research program in a health maintenance organization which provide tangible support for the need to integrate patient interventions with quality assurance activities. A model for quality assurance is described which proposes to include identification of the role of patient behavior in affecting health outcomes, and to develop intervention mechanisms directed towards patients. The experiences from this investigation suggest the need to add patient interventions to the traditional quality assurance efforts of affecting system and provider behaviors. Four of the ten projects conducted are described to illustrate these issues. Topics reviewed are maternity care, hypertension, management of breast disease, and pap smears for high-risk women. These recommendations are particularly appropriate for health maintenance organizations since both quality assurance and health education programs are mandated in the 1973 HMO Act. However, these findings are of relevance to other ambulatory care settings as well.

Urine culture after treatment of uncomplicated cystitis in women.

The follow-up urine culture for urinary tract infection (UTI) is widely recommended, but it is done relatively infrequently in everyday practice. We thought an investigation of its effectiveness was warranted. The study population consisted of 141 women with a culture-proven symptomatic lower UTI. Of these, 56.7% (80) had a follow-up culture and 43.3% (61) did not. The two groups were found to be comparable in important parameters of risk for urinary tract infection and its complications. The relative risk of a subsequent symptomatic UTI was 0.5 for women who did not obtain a follow-up urine culture (95% confidence interval = 0.2 to 1.5). The follow-up urine culture in asymptomatic, healthy women may be unjustified.

Hemophilus parainfluenzae endocarditis.

We describe a case of Hemophilus parainfluenzae endocarditis in a previously healthy 26-year-old man, and review 21 cases from the literature. Although H parainfluenzae is considered to be part of the normal flora of the upper respiratory tract in man, it can cause serious disease. H parainfluenzae endocarditis is often difficult to diagnose. The patients generally had a history of recent infection of the upper respiratory tract, but a majority denied previous heart disease. Upon entry to the hospital, after an average of seven weeks of febrile illness, nearly one third of patients were found not to have a heart murmur. Furthermore, the organism was often difficult to grow from blood cultures, a problem possibly related to the need for accessory growth factors. The mortality with modern therapy was 12%, and the major complication was cerebral embolus. Antibiotic therapy of choice is ampicillin, generally used together with an aminoglycoside, though ampicillin alone may be sufficient.

Psychological aspects of medical care: a training seminar for primary care providers.

A seminar devoted to the psychological aspects of medical care has formed the major portion of the psychiatric training of primary care internal medicine residents at the Kenmore Center of the Harvard Community Health Plan since 1973. The group includes a psychiatrist, a psychiatric nurse, staff physicians, residents, and nurse practitioners. The atmosphere is open and supportive, and discussion focuses on particular situations causing discomfort to members. Content issues include professional identity, relationships with co-workers, and difficulties in handling patients. The group teaches the value of communication and sharing and improves skills in caring for patients.

Nurse-protocol management of low back pain. Outcomes, patient satisfaction and efficiency of primary care.

To test the validity of a nurse-administered protocol for low back pain, a prospective trial of 419 patients was undertaken in a walk-in clinic. In all, 222 patients were randomly allocated to a "nurse-protocol group" in which they were evaluated by one of five nurses using the protocol; the nurses independently managed 53 percent of the patients and referred to a physician patients with potentially complex conditions. In addition, 197 patients in a randomly allocated control group were managed by one of 32 physicians. Care in the experimental and control groups was compared by follow-up telephone contact and by a four-month chart review. There was no significant difference in symptomatic relief or the development of serious disease in the two groups. Nurse-protocol patients expressed greater satisfaction with the care they had received; patient satisfaction correlated positively with symptom relief. In over 95 percent of the patients, there were noncomplex, nonserious, nonchronic conditions as the cause of back pain. We conclude that nurse-protocol management of this generally benign condition in a primary care setting is both effective and efficient.

The prediction of streptococcal pharyngitis in adults.

The usefulness of clinical and laboratory findings for prediction of the presence of Group A streptococci on throat culture and of an increase in antistreptococcal antibodies was investigated in 693 adult patients. Several findings were shown to increase the likelihood of streptococcal isolation, alone and in combination: tonsillar exudate, tonsillar enlargement, tender anterior cervical adenopathy, myalgias, and a positive throat culture in the preceding year. Compared with a frequency of 9.7% in all patients, the probabilities of a positive culture were quite different (ranging from 2 to 53%) in subgroups of patients with different combinations of these clinical findings. The results of a leukocyte count and measurement of C-reactive protein added little additional predictive information. While clinical findings can never predict perfectly the results of a throat culture, they nevertheless can provide useful information--particularly in tending to "rule out" streptococcal infection--in adult patients with pharyngitis.
