Abstract

Objective To explore the potential impact of demand management strategies on patient decision-making in medically non-urgent and urgent scenarios during out-of-hours for children between the ages of 0 and 4 years.

Design and methods We conducted a cross-sectional survey with paper-based case scenarios. A survey was sent to all 797 parents of children aged between 0 and 4 years from four Dutch general practitioner (GP) practices. Four demand management strategies (copayment, online advice, overview medical cost and GP appointment next morning) were incorporated in two medically non-urgent and two urgent case scenarios. Combining the case scenarios with the demand management strategies resulted in 16 cases (four scenarios each with four demand management strategies). Each parent randomly received a questionnaire with three different case scenarios with three different demand strategies and a baseline case scenario without a demand management strategy.

Results The response rate was 47.4%. The strategy online advice led to more medically appropriate decision-making for both non-urgent case scenarios (OR 0.26; 95% CI 0.11 to 0.58) and urgent case scenarios (OR 0.16; 95% CI 0.08 to 0.32). Overview of medical cost (OR 0.59; 95% CI 0.38 to 0.92) and a GP appointment planned the next morning (OR 0.57; 95% CI 0.34 to 0.97) had some influence on patient decisions for urgent cases, but not for non-urgent cases. Copayment had no influence on patient decisions.

Conclusion Online advice has the highest potential to reduce medically unnecessary use. Furthermore it enhanced safety of parents' decisions on seeking help for their young children during out-of-hours primary care. Valid online information on health symptoms for patients should be promoted.

Strengths and limitations of this study

  • The study sample was representative of the Dutch population.

  • Both non-urgent and urgent case scenarios were used to test the demand management strategies.

  • Hypothetical situations were used to test the demand management strategies.

  • Only one amount of the copayment and its effectiveness was tested.

Introduction

In the Netherlands out-of-hours primary care is provided by general practitioner cooperatives (GPCs) and is intended for urgent complaints that cannot wait until the next day.1 However, half of the requests are medically non-urgent,2 and many of these requests can wait until office hours or can be managed with self-care. Inappropriate, non-urgent contacts affect the motivation of triage nurses and general practitioners (GPs), and result in a higher workload which could negatively affect the quality of out-of-hours primary care.3 4 Also, the cost for a consultation at the GPC is higher (about €100) than for a consultation during office hours (€40). These costs are not directly paid by patients. Patients pay a monthly overall premium to their health insurance providers. Primary care is exempted from copayment by patients, contrary to most other types of healthcare. GPs are looking for measures to reduce the number of patients with non-urgent complaints, such as copayment for patients, stricter triage and a larger role for the telephone consultation doctor.4

To support patient decision-making on healthcare use during out-of-hours and regulate demand for primary healthcare, a number of strategies could be effective. Demand management strategies are widely used in the service industry to enable effective and efficient use of capacity. When applied in healthcare, these strategies have the potential to influence the patient’s perceived demand through education, financial incentives or organisational rescheduling.4–6 Accordingly they can reduce demand that is unlikely to improve health5 6 while having minimal effect on genuine, urgent cases so as not to jeopardise appropriate care. Demand management strategies are patient-targeted methods, which approach the aim to prevent overcrowding and enhance the efficiency of the healthcare system, while maintaining high standards of quality and accessibility. The main demand management strategy currently used at GPCs is telephone triage.6 However, patients continue to visit the GPC directly, or get ‘through’ the triage system, with non-urgent complaints. GPs see these patients with non-urgent complaints as one of the most negative aspects of the GPC system.3

Giesen et al 7 found that, of all patient populations, parents with children between the ages of 0 and 4 years most often contact the GPC with non-urgent conditions. In many of these cases, it would be more appropriate to visit the GP during daytime or apply self-care from a medical and societal perspective.7 Previous research also showed that childhood fever does account for a large workload at GPCs.8 Considering the potential effects of demand management strategies in healthcare, it would be valuable to explore which demand management strategies could be effective to reduce non-urgent demand at GPCs for this specific population. The objective of our study was to explore the potential impact of demand management strategies on patient decision-making in both medically non-urgent and urgent scenarios during out-of-hours for children between the ages of 0 and 4 years.

Methods

Design, setting and population

We conducted a cross-sectional survey with paper-based case scenarios. Four GP practices from both rural and urban areas in the east of the Netherlands participated. A survey was sent to all families in their patient population with children aged between 0 and 4 years (n=797). A reminder was sent 2 weeks after the first invitation. The study was conducted between 2013 and 2015.

Questionnaire

A questionnaire was developed over several rounds by researchers and medical professionals. The questionnaire included questions about the background of the patient (gender, age, education level, income, number of children, age of oldest and youngest child), followed by questions related to the paper-based case scenarios. Two pilot studies were conducted to ensure the validity of the survey and test its user-friendliness. In the first pilot study a convenience sample of individuals participated, and in the second pilot study 16 patients from one GP practice participated.

Strategies

In combining the insights on demand for out-of-hours primary care with the findings from previous studies on decision-making and demand management strategies in healthcare, there are several strategies that can potentially be effective to influence the demand for GPCs.3–5 7 We identified the following demand management strategies to be tested in our research: copayment, online advice, overview medical cost and direct GP appointment next morning (see online supplementary appendix A).

Supplementary Material

Supplementary file

Copayment can be implemented via a fee that has to be paid directly by the patient. We set the fee for a GPC at €75 and for the emergency department at €150. Online advice is based on the principle to support patients in their decision-making. We presented online advice that was given by an application certified by the Dutch Society of General Practitioners (NHG). This strategy does not limit the entry to the GPC like copayment does, and may therefore be considered an interesting alternative to the copayment strategy. Another possible effective demand management strategy is to give patients insight into the cost of medical treatments. This strategy would be a midway option between the somewhat controversial copayment and education on medical conditions via online advice. The fourth demand management strategy tested is to enable patients to make an immediate next-working day appointment with their GP via an online scheduling system. This strategy could give patients the certainty of an appointment during office hours, and might thus reduce the probability they will contact a GPC for a health condition that is non-urgent. This strategy would be particularly relevant to the patient group that sought the services of a GPC but were unable to reach their own GP or make an appointment during office hours.9

Case scenarios

The case scenarios were used in an early study about telephone triage and were presented to an expert panel consisting of three triage nurses and three GPs.10 The expert panel determined the ‘reference standard’ regarding the appropriate type of care. We included two non-urgent and two urgent common cases (see online supplementary appendix B). The non-urgent cases were cases for which contact with the GPC (the same day) was not medically necessary, and the urgent cases were cases for which contact with the GPC (the same day) was medically necessary. Combining the case scenarios selected with the demand management strategies, 16 cases were devised (four scenarios each with four demand management strategies). To test all scenario–demand strategy combinations, four questionnaires were developed. Combining the case scenarios with the demand management strategies resulted in 16 cases (four scenarios each with four demand management strategies). Each parent randomly received a questionnaire with three different case scenarios with three different demand strategies and a baseline case scenario without a demand management strategy. Due to a mistake in one of the cases in the questionnaire, we excluded the answers of 141 respondents regarding that case. The baseline case scenario was included to test how respondents would react in the different case scenarios when no demand management strategy was included.

The effects of demand management strategies on patient decision-making were verified by testing if the choices made by the respondents matched the reference standard of the expert panel. To test this, we rearranged the answers into categories. The answers to the non-urgent scenarios were categorised into ‘medically appropriate demand’ or ‘overdemand’, while the answers to the urgent scenarios were categorised into ‘underdemand’, ‘medically appropriate demand’ and ‘overdemand’ (table 1).

Statistical analyses

Descriptive statistics were used to describe the characteristics of the respondents and the percentages of overdemand and underdemand for each strategy. The choices of the parents (with either overdemand or underdemand coded as ‘1’ and the other choices as ‘0’) have been tested in two separate logistic regression analyses at the case level. The answers to the baseline case scenarios served as a reference category, meaning that both non-urgent and urgent scenarios presented with demand management strategies have been tested against answers given for the baseline scenarios. We corrected for patient characteristics (gender, age, amount of children, education level and income) and added the variable GP practice to account for clustering of patients within GP practices. Analyses were performed in SPSS V.22.0.

Results

Characteristics of respondents

The response rate was 47.3% (n=377), providing answers to 1367 cases. Of the respondents 42.5% lived in urban areas, 17% in suburban areas and 40.6% in rural areas (table 2). Most of the participants finished tertiary school (41.6%) and indicated their income as similar to the average Dutch household income (34.5%).11 The average number of children per parent was 2.1. The mean age of the oldest child was 4.8 years and of the youngest child 1.7 years.

Characteristics of respondents (n=377)

Case scenarios

Regarding the non-urgent scenarios, 41.7% of the parents made an overdemand choice (table 3). For the urgent scenarios, 50.3% of the respondents made an underdemand choice and 3.9% an overdemand choice.

Table 3

Case scenarios with demand management strategies

Overall, the percentage of parents who made an overdemand choice for the non-urgent case scenarios without a demand management strategy was 41.7% (table 4). By providing the strategy ‘online advice’, the percentage of overdemand decreased by 30.4%. The strategy ‘copayment’ was found to reduce the probability of overdemand to 31.7%, realising a decrease of 10.0% compared with the baseline strategy. We did not find large differences when the strategies ‘GP consult planned’ and ‘overview of medical cost’ were used.

Table 4

Overdemand and underdemand for each demand management strategy (%)

An underdemand solution for the urgent case scenarios without a demand strategy (‘baseline’) was chosen by 50.3%. When using the strategy ‘online advice’, 16.5% chose an underdemand solution, a decrease of 33.8%. The strategy ‘overview medical cost’ reduced the probability of underdemand by 10.9%. With the use of the strategy ‘GP consult planned’, the probability of an underdemand decision was decreased by 9.7%. The strategy ‘copayment’ seems to have no influence, as with this strategy 50.0% still chose an underdemand solution.

Influence of demand management strategies on non-urgent and urgent case scenarios

Table 5 shows that when the strategy ‘online advice’ was used for non-urgent cases, parents more frequently made a medically appropriate healthcare choice (OR 0.26; 95% CI 0.11 to 0.58). The other strategies had no influence on the parents’ decisions in non-urgent cases. We also found that parents with more than one child made an appropriate choice more often than parents with just one child (OR 0.64; 95% CI 0.43 to 0.96).

Logistic regression for overdemand and underdemand†

For the urgent cases, we found that the application of online advice influences parent decision-making positively, resulting in more medically appropriate choices (OR 0.16; 95% CI 0.08 to 0.32). The strategy of showing the medical cost of a visit to the GPC also results in more medically appropriate choice behaviour (OR 0.59; 95% CI 0.38 to 0.92), as did the strategy of offering the patient the option to plan a medical consultation with the GP (OR 0.57; 95% CI 0.34 to 0.97). Furthermore, parents with more than one child more frequently chose an underdemand solution for a high-urgent condition (OR 2.04; 95% CI 1.39 to 2.98), and similarly older parents more regularly chose an underdemand solution (OR 0.95; 95% CI 0.92 to 0.98).

Discussion and conclusion

Discussion

The findings of this study imply that decisions on healthcare seeking by parents of young children can be influenced. For both non-urgent and urgent case scenarios, about half of the parents did not chose the most medically appropriate decision. Demand management strategies have the potential to help patients make medically appropriate decisions. The strategy ‘online advice’ seems to have the highest potential to positively influence patient demand as it influenced decisions in both urgent and non-urgent cases. The use of this strategy has both the potential of reducing medically unnecessary use of the GPC and could also enhance safety in healthcare, as patients are more likely to contact a doctor in urgent cases. Comparable results have been found in studies on the management of chronic diseases such as depression and lower back pain.12–14 In the questionnaire a relatively customised advice (applicable to the specific condition) was presented, and it was mentioned that the advice was given by an online application certified by the Dutch Society of General Practitioners (NHG). This set-up of posting a ‘certified’ and customised advice might have had a positive influence on the patients’ willingness to follow it. This is also mentioned by parents in a British study about information needs of parents for acute childhood illness.15 In addition, the capabilities of the person receiving the advice also influence the way a person acts on it.

Even though 9 in 10 inhabitants in the Netherlands access the internet every day, it is still debatable whether all would actually use an online application if they would be worried or panicking about their (child’s) condition. Also, it is essential to remain vigilant to how access limitations might exclude certain groups of society from accessing such information. A recent study shows that people who are older, have a higher income or live in rural areas are less likely to use mobile health applications.16 On the other hand, access to internet on smartphones or notebooks is also high in socially deprived populations.

We also found that implementing copayment or giving an overview of the medical cost did not affect patient decision-making for non-urgent scenarios. In addition, for the urgent case scenarios there was no influence from implementing copayment, which would imply that it does not affect patient safety. Other studies also found that copayment was not an important driver for patient decision-making,17 18 but other studies found some effects of copayment. A study at the emergency department showed a reduction in demand from patients with non-urgent conditions.19 In line with this outcome, some argue that copayment stimulates patients to consider whether they really need healthcare at that moment. This would eventually contribute to lowering collective healthcare costs.20 On the other hand, critics argue that the fee could deter patients with serious illnesses from visiting the emergency department21 and could lead to greater inequity, especially for socially deprived patients.22 23

While we expected the ‘GP consult planned’ demand management strategy to affect the non-urgent cases, it only appeared to affect patient decision-making positively in relation to urgent conditions. Seemingly those seeking help for a non-urgent problem are not easily influenced by an organisational strategy.

Regarding patient characteristics, we found that patients with more children seem to make more underdemand healthcare choices, resulting in less overdemand. A possible explanation is that these parents, due to experience, are less prone to panic. Interestingly, they seem more likely to underestimate medical urgencies. Also, the probability that parents will choose an underdemand solution increases when a parent is older; we could philosophise that older parents are more able to assess a healthcare problem.

Strengths and weaknesses and recommendations for further research

The selected sample is diverse in terms of residential zones, income, education, age and number of children. These characteristics reflect the Dutch population.24 We chose to use written case scenarios. A drawback of this design is that respondents were confronted with hypothetical situations; consequently, emotional reactions or actual financial payments that occur in real-life situations are not completely reflected in this research. Besides, it is possible that the respondents were eager to answer ‘correctly’, especially for the cases in which the strategy online advice was incorporated as they were provided with information about the appropriate response. This may have inflated the effect of this strategy. On the other hand, the information scenario was closer to reality (responders actually received it), which has enhanced the impact of this strategy. Prospective evaluation studies of demand management strategies, ideally designed as randomised trials, are required to examine their impact.

We used two non-urgent and two urgent case scenarios to test the demand management strategies. Although the cases were validated by an expert panel and they had consensus about the appropriate choice, we saw great differences in answers between the two urgent cases. We noticed that many parents chose an underdemand solution for one of the urgent cases (child with fever). In hindsight, as we did not expect such a high percentage of parents to make an underdemand choice for the urgent case scenarios (especially for the child with fever case), this case may not have been the best scenario to test the demand management strategies. Further research using more, alternate case scenarios is needed to confirm the results of this study.

There might be a relation to the amount of the copayment and its effectiveness.4 In this research we only tested one amount for the GPC, but if policymakers would want a more conclusive assessment of this strategy, different amounts should be tested. Finally, although the described strategies were merely effective under either urgent or non-urgent conditions, it would be interesting to research the effects of implementing strategies simultaneously. For example, combining online advice and online overview of medical cost could possibly increase the effectiveness of the strategies.

Conclusion

We conclude that there are demand management strategies that can influence a patient’s ability to make medically appropriate healthcare choices for urgent and non-urgent conditions during out-of-hours. Guiding and advising patients online appears to have high potential, as it influences patient decision-making positively in both urgent and non-urgent conditions. Advising patients on what decision to take when a health condition occurs offers the patients a level of certainty that can positively influence their decision-making. Further research with more case scenarios is needed to confirm the results of this study. It is also necessary to study the impact of this strategy on patient safety in practice.

Practice implications

Our study can have broad implications in a world where more people use the internet and policymakers are struggling to limit healthcare costs while maintaining high quality and safety in healthcare. This research shows the great potential of online health applications and we believe that an independent, certified and customised tool, such as thuisarts.nl,25 should be promoted. It may lead to a reduction in the use of GPCs for non-urgent complaints that could wait until the next day and to safer use for patients with urgent complaints.
