Abstract

Aim of this study was to obtain a picture of the nature of the primary care pediatricians’ visits during a winter season. We investigated reasons for visits, diagnosis, and pattern of prescription in 284 children. The reason for visit was a planned visit in 54% of cases, a well-being examination in 26%, and an urgent visit for an acute problem in 20% of cases. Cough was the most common symptom reported (61%). The most common pediatricians’ diagnosis was flu-like syndrome (47%). No disease was found by pediatrician in 27% of children with a symptom reported by caregivers. Antibiotics were prescribed in 25% of children, the vast majority of which affected by viral respiratory infections. The unjustified access to physician’s visit may lead to a inappropriate prescription of drugs.

Primary care pediatrician Diagnosis Prescription Flu-like illness Children

Introduction

Primary ambulatory health care is important for maintaining good health in individuals by providing preventive interventions and early treatment of illness [1]. Children access the primary care health system for three main reasons: preventive care, illness care, and trauma or injury [1]. A progressive increase in ambulatory care visits has been reported in the last years in U.S. [2, 3]. The global physicians’ activity is loaded with important day-of-the-week and seasonal variations [4]. During the winter, the annual outbreak of influenza leads to a high rate of outpatient visits and antibiotic prescription in children [510]. Understanding the pattern of visits at primary care pediatricians (PCPs) offices is important to develop policies aimed to improve access to health services and quality of care provided by physicians.

Aim of this prospective study was to obtain a picture of the nature of the PCPs visits during a winter season. The major reasons for visits, pattern of diagnosis, impact of flu-like illness on PCPs activity, and pattern of prescriptions are analysed.

Methods

The survey was conducted during an 8-week winter period (December-January) in three PCPs practices in Naples (Campania Region, Italy) in 2011–2012 season. The PCPs enrolled in the study, who have similar age, year of specialization and number of assigned patients, served globally 2751 children aged 0–14 years. A sample of consecutive children was included. Data were prospectively collected by a pediatric nurse through direct observation during PCPs’ visits. The nurse visited the PCPs offices 3 times a week for each paediatrician, for a total of 72 working shifts. All children observed in the index days were enrolled and data were collected through a standardized form including patient demographic information, clinical data, time to visit, type of visit, patient’s principal reason for visit, physician diagnosis, and prescriptions. The research was conducted according to the Helsinki declaration, approval by ethical committee was not formally required being an observational study. However, the informed consent was obtained by legal guardians of enrolled children.

Time to visit was defined as the period between the onset of symptoms and the medical visit. It was classified as: urgent visit (a visit for an acute onset problem or for an exacerbation of a chronic problem), planned visit (a visit for a deferred symptom, check for a chronic conditions, or immunization), visit for child well-being examination included in the PCPs’ routine activity. The main reason for visit reflects caregivers’ perspective of the major reason for seeing care, and it may differs from final physician’s diagnosis.

Criteria for diagnosis of influenza like illness (ILI) were the sudden onset of fever, with respiratory and/or systemic symptoms during the influenza season [4, 11]. Definition of upper respiratory tract infection (URTI) was based on a single symptom or on the presence of a cohort of different respiratory symptoms, irrespective of season and presence of fever.

Results

A total of 284 children (131 males; mean age 4.8 ± 3.7 years; 12% with an underlying chronic conditions) were enrolled (Figure 1). The type of visit was: a planned visit in 153/284 (54%) cases, a well-being examination in 75 (26%) and an urgent visit for an acute problem in 56 (20%). A higher percentage of urgent visits were recorded on Monday (Figure 2).

Caregivers required a visit because of symptoms in 188/284 (66%) children. Specifically, all 56 caregivers requiring an urgent visit reported the presence of one or more symptoms. Other 132 children presenting symptoms were seen during planned visits. Cough was the most common symptom in all age-groups (115/188, 61%), followed by fever (80, 43%), upper respiratory symptoms (44, 23%), and other symptoms such as abdominal pain, headache, vomit (33, 17%). The symptom distribution showed an age-related pattern, with upper respiratory tract symptoms more frequent in children aged 0–2 years (38%), compared to the other groups (p < 0.001) (Figure 3).

Figure 3

Patient’s principal reason for visit according to age groups in 188 children presenting with clinical symptoms.

Among 209 children receiving a planned or an urgent visits, 137 (73%) had a final diagnosis by PCPs of an acute disease. Specifically, in 51 out of 188 (27%) children whose caregivers have required a visit because of presence of symptoms, no disease at medical examination was found by PCPs. The most common diagnoses made by PCPs were ILI (65 cases, 47%), URTI (40 cases, 29%), pneumonia (5 cases, 4%).

Time to visit was significantly related to the final diagnosis. Caregivers of children with a final diagnosis of ILI or URTI required more frequently a visit within one day from the onset of symptoms compared to the groups with lower respiratory tract infections or other diagnosis (p = 0.025) (Figure 4).

In the group of 65 children (mean age 5.7 ± 3.4 years) receiving a diagnosis of ILI, at the time of PCPs visit the most common symptom was fever (78%), followed by cough (68%) and other upper respiratory tract symptoms (32%), with no difference in age distribution (Figure 5).

As additional data, only 5% of enrolled children (and only one of 33 children with an underlying chronic condition) had already received or were going to receive seasonal influenza vaccination.

One or more medications were prescribed to 96/137 (70%) children with a final diagnosis made by PCPs. Anti-inflammatory drugs were prescribed alone in 62 (65%) cases, antibiotics in 22 (23%) cases, and both medications in 12 (12%) children. Potential determinants of antibiotic prescription were child age and duration of symptoms. A trend toward higher prescription in younger children was registered, although not statistically significant (p = 0.1). A duration of symptoms of 6–13 days was more frequently associated with antibiotic prescription (44% of children in group receiving antibiotics versus 26% not receiving antibiotics; p = 0.04). The diagnosis in 34 children receiving antibiotics were: ILI in 13 (38%) cases, URTI in 12 (35%) cases, pneumonia in 5 (15%) and “other diagnosis” in 4 (12%) cases. According to the presence of an underlying chronic disease, a trend in lower prescription of antibiotics in at-risk children compared to otherwise healthy children was registered (17% versus 24%, p > 0.05).

In the group of 65 children with ILI, anti-pyretics were prescribed in 47 (72%) cases, antibiotics (alone or together with anti-pyretic) in 13 cases (20%), and other medications in 11 (17%) cases. The most common reasons for antibiotic prescription were: persistence of respiratory symptoms without improvement for >5 days (3 children), clinical signs of pneumonia (2 cases), fever lasting >3 days (3 cases), and self-prescription by parents (5 children). PCPs required laboratory (3 cases) or radiological investigations (1 case) in few cases.

Discussion

Ambulatory health care in the U.S. has been examined by analyzing data from multiple settings [2, 12]. About 20% of all ambulatory visits in 2007 in the U.S. were due to non illness conditions, such as routine check-up [3]. Preventive care is incorporated into pediatric practice in order to promote health for individual children and adolescents and it is a frequent reason for ambulatory visits, accounting for 20-30% of them [13, 14]. As a consequence, PCPs spent a considerable time and efforts for non urgent visits, with a possible decreased time to visit more serious patients in their practice. Annually, during influenza season, an increase in the activity at PCPs office is observed [9, 10] and the high number of office-based preventive care interventions may exceed the capacity of the health care system to fulfil the requests for acute conditions. Such an increase of the need of medical visits was confirmed in our study. A major burden on childhood health care request may be more frequent during an influenza pandemic [1517]. During the last 2009 H1N1 pandemic, the highest consultation rate and hospitalization for ILI were recorded in children [15, 18]. It can be hypothesized that the inappropriate overflow of health care services registered was due, at least in part, to the anxiety and concern by the population for H1N1 influenza, also because of extensive media campaigns, rather than with a real increased incidence or severity of ILI. However, a major burden of requests may occur independently of specific concern. To confirm the inappropriate request for a medical visit by caregivers, our data showed that more than 20% of children who were visited at PCPs had no disease as final diagnosis and no real need for medical consultation.

Respiratory tract diseases were the most common diagnosis, accounting for about 37% of all visits, and for more than 70% of children with a final diagnosis of an acute disease. It is to note that in our study, the number of ILI cases was based on practitioner’s medical visit, providing a more reliable information compared to previous studies [15, 17].

In this survey, only 5% of enrolled children had received seasonal influenza vaccination. Although in Italy seasonal influenza vaccine is recommended and offered free of charge to children with chronic conditions, flu vaccination rates are very low in almost all pediatric at-risk categories [1923]. Indeed, in our population there was only one vaccinated child out of 33 children that should have been immunized because of a chronic condition.

The high rate of antibiotic prescription deserves a specific comment. Antibiotics are still commonly prescribed for children with conditions for which they provide no benefit, including respiratory infections whose etiology is likely a viral infection [2426]. As much as 26% of visits of children aged <5 years resulted in an antibiotic prescription in office-based settings, compared to 32% in those emergency departments [27]. It has been reported that in Italian southern regions antibiotics are more frequently prescribed that in the northern and central regions [28, 29]. In the present study, antibiotics were prescribed in 25% of children with a diagnosis of illness made by PCPs. However, antibiotics were inappropriately prescribed for viral infections (ILI or URTI) in more than 70% of cases. Although not statistically significant, at-risk children received less antibiotics than “otherwise healthy” children. This may be related to the presence of other long-lasting treatments, or in some cases to the consultation with referral institution for chronic diseases (not rare for chronic patients).

In conclusion, based on our data, there is a clear need to limit the unjustified access to physician’s visit that may lead to a consequent inappropriate prescription of drugs in addition to costs for health care system and families. An approach based on a telephone triage by PCPs might reduce the inappropriate access to their offices, and the excess of non medical access to the emergency department. Moreover, a telephone triage could provide information and advice to patients, and could help in optimizing the PCPs activities, with specific initiatives such as postponing the well-being visits. During a period of high burden of infectious disease it is necessary to develop strategies in order better allocate health care resources and ensure a high quality of care provided by primary care physicians.
