Primary care and public emergency department overcrowding.

OBJECTIVES: Our objective was to evaluate whether referral to primary care settings would be clinically appropriate for and acceptable to patients waiting for emergency department care for nonemergency conditions. METHODS: We studied 700 patients waiting for emergency department care at a public hospital. Access to alternative sources of medical care, clinical appropriateness of emergency department use, and patients' willingness to use nonemergency services were measured and compared between patients with and without a regular source of care. RESULTS: Nearly half (45%) of the patients cited access barriers to primary care as their reason for using the emergency department. Only 13% of the patients waiting for care had conditions that were clinically appropriate for emergency department services. Patients with a regular source of care used the emergency department more appropriately than did patients without a regular source of care. Thirty-eight percent of the patients expressed a willingness to trade their emergency department visit for an appointment with a physician within 3 days. CONCLUSIONS: Public emergency departments could refer large numbers of patients to appointments at primary care facilities. This alternative would be viable only if the availability and coordination of primary care services were enhanced for low-income populations.

Prophylactic antibiotics at caesarean section do not reduce costs.

A prospective audit of 200 patients was undertaken to determine the effectiveness of prophylactic antibiotics at caesarean section in reducing the cost of postnatal care. The main outcome measures were the cost-effectiveness of this treatment in reducing the cost of care and incidence of infection. The results show that the routine administration of prophylactic antibiotics had no significant effect on infection rates, the prescribing of puerperal antibiotics or the duration of stay in the postnatal period. The total cost of antibiotics in the prophylaxis group was over four times that in the non-prophylaxis group. The results of this study suggest that routine administration of antibiotics at caesarean section does not reduce the costs of care in the puerperium.

Collecting data to evaluate the effect of health policies on vulnerable populations.

Public health policies often have disproportionate effects on the poor and other vulnerable groups. Standard survey techniques are often difficult to apply to these vulnerable populations, and many data bases systematically omit such individuals. The purpose of this paper is to review our experience in collecting primary survey data from public hospital, mentally ill, HIV-infected, and non-English-speaking patients. Important issues in conducting research on these populations include proper selection of subjects and comparison groups and difficulties involved in recruitment and enrollment of subjects. Maintaining longitudinal data on these populations is difficult and often requires tracking, secondary contacts, home visits and community outreach, and the use of organizations, institutions, and networks. Investigators must also pay careful attention to ethical issues involved in conducting research on vulnerable populations.

Percutaneous balloon pericardiotomy in the management of recurrent malignant pericardial effusions.

Two patients with recurrent symptomatic pericardial effusions secondary to malignant disease were successfully treated by percutaneous balloon pericardiotomy. Open surgery was avoided and the procedure was completed under local anaesthesia in less than 40 minutes. The first patient was free of recurrence at nine months but pericardial effusion recurred at two months in the second patient. Percutaneous balloon pericardiotomy offers a potentially important new means of relieving recurrent tamponade and substantially reduces trauma to the patient.

CD4 lymphocyte count as an indicator of delay in seeking human immunodeficiency virus-related treatment.

BACKGROUND: As many as half of patients infected with the human immunodeficiency virus who are medically eligible for Pneumocystis prophylaxis and zidovudine treatment have not received these treatments. We used the CD4 lymphocyte count as an indicator of delay in seeking treatment among patients infected with human immunodeficiency virus and assessed whether insurance status was associated with the stage of illness when care is initiated. METHODS: Data from 96 patients who initiated medical care at a university acquired immunodeficiency syndrome clinic from August 1989 to January 1991 were retrospectively reviewed. RESULTS: Patients initiated care at a relatively late stage of illness (mean CD4 lymphocyte count, 0.37 x 10(9)/L [369/mm3]), and 29% were below the threshold for Pneumocystis prophylaxis. Patients with private insurance had significantly lower CD4 counts (mean, 0.27 x 10(9)/L) than did individuals with public insurance (mean, 0.46 x 10(9)/L). CD4 counts did not increase during the 18-month study period. CONCLUSIONS: The majority of patients infected with human immunodeficiency virus are eligible for medical therapy and could benefit by initiating care sooner. Private insurance was not associated with initiating early care, supporting anecdotal reports that some privately insured individuals may be reluctant to seek care for a human immunodeficiency virus-related condition.

Comparison of nebulized and sprayed topical anaesthesia for fibreoptic bronchoscopy.

We compared the efficacy of nebulized (N) and sprayed (S) topical anaesthesia prior to fibreoptic bronchoscopy in a blinded study involving 54 patients aged 57 +/- 26 yrs (mean +/- SD). Cough frequency, recorded on cassette tape, was the index of efficacy. All patients received 100 mg lignocaine sprayed into the pharynx, or nebulized in random order prior to bronchoscopy, and all received intravenous diazepam sedation. Each patient received a further 100 mg of lignocaine solution through the bronchoscope onto the vocal cords and major airways during the procedure. No significant difference was found in overall cough frequency between N and S groups (8.7 +/- 6.9 coughs.min-1 N vs 10.5 +/- 6.0 S), and cough frequency was also similar between N and S during the periods above and below the vocal cords. Furthermore, no differences were found in cough frequency between N and S among smokers, patients with asthma and COPD, and patients who had a biopsy procedure, although a trend was seen in all comparisons towards a lower cough frequency with the nebulized route. Most patients in the S group found the spray unpleasant, whereas only one in the N group complained. We conclude that nebulized and sprayed lignocaine have similar efficacy as topical anaesthetics in fibreoptic bronchoscopy, but patient preference favours the nebulized route.

Consequences of queuing for care at a public hospital emergency department.

OBJECTIVE: To determine whether the length of a queue at a public hospital emergency department was associated with increased likelihood of patients' leaving without being seen by a physician and whether leaving adversely affected patients' health or affected their subsequent use of health care services. DESIGN: Observational cohort. Patients were surveyed during 1 week in July 1990 and received a follow-up survey 7 to 14 days later. The responses of patients who left without being seen by a physician were compared with those who were seen by a physician. SETTING: Emergency department at San Francisco (Calif) General Hospital. PATIENTS: All English-, Spanish-, and Cantonese-speaking adults waiting for emergency care were eligible. Of 882 eligible individuals, 700 agreed to participate; 85% of enrolled subjects saw a physician and 15% left without being seen. Demographic characteristics of patients who were and who were not seen were not significantly different. MAIN OUTCOME MEASURES: Emergency department waiting time and changes in patients' self-reported health. RESULTS: Patients were more likely to leave as waiting times increased. At follow-up, patients who left without being seen were twice as likely as those who were seen to report that their pain or the seriousness of their problem was worse. Only 4% of patients who left required subsequent hospitalization, but 27% returned to an emergency department. CONCLUSION: Many patients can appropriately decide whether their problem is truly urgent and make alternative plans in the face of long waits, but the health of some patients may be jeopardized by long queues for emergency care.

A public hospital closes. Impact on patients' access to care and health status.

We studied the impact of the closing of a public hospital on patients' access to care and health status. We surveyed individuals who had been medical inpatients at Shasta General Hospital, Redding, Calif, in the year prior to its closing and compared them with those in a second county, San Luis Obispo, whose public hospital did not close. Surveys were administered after the closing of Shasta General Hospital and 1 year later. We assessed outcomes using the Medical Outcomes Study Short Form and a series of transition questions that asked about changes in health over time. Data were available for 88% of patients at 1 year: 219 from Shasta County and 195 from San Luis Obispo County. At follow-up, the percentage of patients from Shasta County who reported no regular provider increased from 14.0 to 27.7 and the percentage who reported they were denied care rose from 10.8 to 16.9. Meanwhile, patients in San Luis Obispo County reported improved access to a regular provider and the level of denied care was unchanged. Patients in Shasta County had significant declines on the Medical Outcomes Study Short Form in health perception, social and role function, and increases in pain as compared with those patients in San Luis Obispo County. The closing of a public hospital had a significant effect on access to health care and was associated with a decline in health status.

Measuring health changes among severely ill patients. The floor phenomenon.

The interest in measuring health status with survey instruments has not been matched with an analysis of their performance characteristics in the field. We used the Medical Outcome Study Short Form (MOS-20) to assess health outcomes among patients who were hospitalized in one of two public hospitals. We mailed the MOS-20 and a series of transition questions, which asked about changes in health, to patients admitted in the previous year. We received 414 completed surveys from 480 patients at baseline and follow-up data on 90% of these patients six months later. Baseline MOS-20 scores for study patients were significantly lower, corresponding to worse health, than previously reported outpatient and general population cohorts. While the direction of change on serial applications of the MOS-20 paralleled the patients' perception of change reported on transition questions, many patients who reported their health had become worse also recorded the lowest possible score on the MOS-20 at baseline. These low baseline MOS-20 scores prohibited the recognition of larger declines in function during the follow-up period. This floor in the response range creates an instrument bias against documenting a decline in health among severely ill patients, the group in which it may be most important to detect such a change.
