The Impact of Change in Hospital Admissions When Primary Care Is Provided by a Single Primary Care Physician: A Cohort Study Among HMO Patients in Israel.

OBJECTIVES: An Israeli health maintenance organization (HMO) changed its policy from freedom of choice in choosing any primary care physician (PCP) to provide health care to one provider allocated to the patients. We examined outcome measures before and after the intervention in the study population. DESIGN: During a 2.5-year period (from June 2013 to December 2015), continuity of care by PCPs was achieved by a single provider. The change was computed for each participant according to the most visited PCP in the last year. PARTICIPANTS: A total of 208,286 patients aged 20 and older fulfilled the inclusion criteria. MAIN OUTCOME MEASURES: Future likelihood of hospitalization, number of PCP visits, and medication use before and after the intervention. RESULTS: After controlling for demographics, high continuity of care before and after intervention was associated with a lower likelihood of hospitalization for any condition (adjusted odds ratio [OR] = 0.90; 95% confidence interval [CI], 0.85-0.95; p = 0.003). No significant change was recorded for number of ambulatory visits or medication use. CONCLUSIONS: Changing Leumit HMO policy to continuity of care with a single provider is associated with a decreased future likelihood of hospitalization. This suggests that policies that encourage patients to concentrate their care with a single provider may lead to lower hospitalization rates and possibly lower healthcare costs.

Does a policy that requires adherence to a regular primary care physician improve the actual adherence of patients?

BACKGROUND: Continuity of care by the same personal physician is a key factor in an effective and efficient health care system. Studies that support the association between high adherence and better outcomes were done in settings where allocation to the same physician was a long-term policy. OBJECTIVES: To evaluate the influence that changing organizational policy from the free choice of a primary care physician to a mandatory continuity of care by the same physician has on adherence to a personal physician. METHODS: A cross-sectional study based on electronic databases; comparison of adherence and demographic characteristics (sex, age, and socio-economic status) of 208,286 Leumit enrollees who met the inclusion criteria, according to change in the adherence to a personal physician. To evaluate adherence, we used the Usual Provider of Care (UPC) index, which measures the number of visits made to the personal doctor out of the total primary care physician visits over the same period. The patients were divided into groups according to their UPC level. RESULTS: The data shows that 54.5% of the patients were high adherers even before the organizational change; these rates are similar to those published by various organizations worldwide, years after mandating continuity of care by the same physician. In the year following the intervention, only 34.5% of the patients changed the level of their adherence group. Of these, 64% made a shift to a higher adherence group. Before the intervention, the high adherers were older (mean age 57.8 vs. 49.3 years in the low adherers group) and from a higher SES (mean SES status 9.32 vs. 8.71). After the intervention, a higher proportion of older patients and patients from a higher SES changed their adherence to a higher group. Sex distribution was similar over all the adherence level groups and did not change after the intervention. CONCLUSIONS AND POLICY IMPLICATIONS: A policy change that encouraged adherence to an allocated primary care physician managed to improve adherence only in specific groups. Health organizations need to examine the potential for change and the groups they want to influence and direct their investment wisely. TRIAL REGISTRATION: retrospectively registered.

Antibiotic use in patients with erysipelas: a retrospective study.

BACKGROUND: Erysipelas is a skin infection generally caused by group A streptococci. Although penicillin is the drug of choice, some physicians tend to treat erysipelas with antibiotics other than penicillin. OBJECTIVES: To define the pattern of antibiotic use, factors affecting antibiotic selection, and outcome of patients treated with penicillin versus those treated with other antimicrobial agents. METHODS: A retrospective review of charts of adult patients with discharge diagnosis of erysipelas was conducted for the years 1993-1996. RESULTS: The study group comprised 365 patients (median age 67 years). In 76% of the cases infection involved the leg/s. Predisposing condition/s were present in 82% of cases. Microorganisms were isolated from blood cultures in only 6 of 176 cases (3%), and Streptococcus spp. was recovered in four of these six patients. Cultures from skin specimens were positive in 3 of 23 cases. Penicillin alone was given to 164 patients (45%). Other antibiotics were more commonly used in the second half of the study period (P < 0.0001) in patients with underlying conditions (P = 0.06) and in those hospitalized in the dermatology ward (P < 0.0001). Hospitalization was significantly shorter in the penicillin group (P = 0.004). There were no in-hospital deaths. CONCLUSIONS: We found no advantage in using antibiotics other than penicillin for treating erysipelas. The low yield of skin and blood cultures and their marginal impact on management, as well as the excellent outcome suggest that this infection can probably be treated empirically on an outpatient basis.
